Description

Refrigerator with a door
Technical Field
The present invention relates to a refrigerator, and more particularly, to a structure for improving the rigidity of a refrigerator main body.
Background
In recent years, from the viewpoint of energy saving and space saving and capacity increase, the thickness of the refrigerator is being reduced while improving the heat insulating performance of the refrigerator main body. Specifically, the refrigerator includes an outer box and an inner box, and a foamed heat insulating material is filled between the outer box and the inner box, and a vacuum heat insulating material is disposed between the outer box and the inner box. With this structure, the heat insulation of the refrigerator main body is improved, the thickness of the refrigerator main body is reduced, and space saving and capacity increase are achieved.
Recently, a further increase in capacity has been progressing due to changes in living environment and the like. Therefore, it is a great problem to improve the rigidity of the refrigerator main body.
In order to solve such a problem, various studies have been made on a conventional refrigerator main body to improve the rigidity thereof (for example, see patent document 1).
Fig. 34 shows a structure of the refrigerator main body described in patent document 1. As shown in fig. 34, refrigerator main body 3400 includes an outer box 3403. The outer case 3403 has a top plate 3401 and side plates 3402. The outer case 3403 has a substantially L-shaped frame reinforcing member 3404 along the lower side of each of the side plates 3402. The front sides of the side plates 3402 are connected by a front plate member 3405. Further, the front plate 3405 and the frame reinforcing member 3404 are coupled by a screw 3406 at a lower corner portion on the front surface side of the outer case 3403.
According to this conventional structure, since the side plate 3402, the front plate member 3405, and the frame reinforcing member 3404 are coupled, the rigidity of the outer box 3403, that is, the refrigerator main body 3400 can be increased.
However, in recent refrigerators, in addition to the size increase of the refrigerator main body 3400, the door is formed of a glass door from the viewpoint of improving the quality, and the weight of the refrigerator main body and the glass door together becomes considerably large. Therefore, it is difficult to withstand long-term use only with the above-described conventional structure in which the rigidity of the refrigerator main body is increased.
In particular, as described above, since recent refrigerators have a large capacity for space saving and a thin thickness, there is a concern that refrigerator main body 3400 may be deformed when used for a long period of time.
Further, since the door is supported in a cantilever manner, the portion of the door pivotally supporting the refrigerator main body side plate does not resist the cantilever moment load of the door, and is slightly deformed with the passage of time. In addition, in the case of the left and right split doors, a step difference is generated between the left and right doors, which may become noticeable as time passes.
In particular, when the left and right door sizes of the left and right split doors are large on one side and small on the other side, the cantilever moment loads applied to the doors of the left and right side plates of the refrigerator main body are likely to be deformed in different magnitudes, and the possibility of deformation increases.
In general, a refrigerator is configured such that a refrigerator main body is partitioned into a plurality of storage compartments, such as a refrigerating compartment, a freezing compartment, and a vegetable compartment, by partition plates, and each storage compartment is configured to be openable and closable by a door. In such a refrigerator, it is known that a storage chamber between a refrigerating chamber and a freezing chamber is further divided into two right and left chambers, and one of the chambers is configured as an ice making chamber and the other is configured as a quick freezing chamber or a switching chamber capable of switching a temperature range (for example, see patent document 2).
Fig. 35 shows a refrigerator described in patent document 2. In the refrigerator shown in fig. 35, a refrigerator main body 3501 is provided with a refrigerator compartment 3502, a freezer compartment 3503, and a vegetable compartment 3504. The storage compartment between refrigerating compartment 3502 and freezing compartment 3503 is divided into two compartments, i.e., a left compartment and a right compartment, and ice-making compartment 3505 and quick-freezing compartment or switching compartment 3506 are provided. The ice making compartment 3505 and the freezing compartment or switching compartment 3506 are divided as follows. That is, the end surface of the vertical separator upper part 3509a projecting downward from the upper partition plate 3508 and the end surface of the vertical separator lower part 3509b projecting upward from the lower partition plate 3510 are brought into abutting contact with each other, whereby the decorative cover (not shown) is disposed in front of the partition plate and the partition plate (not shown) is disposed behind the partition plate.
In the refrigerator having the above configuration, since the quick freezing chamber or the switching chamber 3506 is provided in addition to the refrigerating chamber 3502, the freezing chamber 3503, and the vegetable chamber 3504, meat, fish, and the like can be kept in a semi-frozen state, and the refrigerator has an advantage of being excellent in usability.
Further, since the quick freezing compartment or the switching compartment 3506 is located at a substantially central portion in the vertical direction of the refrigerator main body 3501, a partition plate partitioning the quick freezing compartment or the switching compartment 3506 and the like is a strong member reinforcing a substantially central portion of the opening of the long and thin refrigerator main body 3501, and there is also an advantage that the rigidity of the refrigerator main body 3501 is improved.
However, in recent refrigerators, the size of the refrigerator main body 3501 is increasing due to changes in living environments and the like, and as described above, from the viewpoint of high-quality products, door glasses are being used to increase the weight of the refrigerator. Therefore, the refrigerator main body 3501 is required to have a higher level of rigidity, and improvement of the rigidity is becoming a great problem.
In particular, when the refrigerator main body 3501 is increased in size, not only the vertical direction but also the lateral direction of the refrigerator main body is increased depending on the height of the user. Therefore, the top partition plate and the bottom partition plate, which also serve as the strength members of the refrigerator main body 3501, have a large lateral length, and if the plate thickness is kept at a conventional level, the strength members do not function sufficiently. In this respect, it is also a great problem that the rigidity of the refrigerator main body 3501 is improved.
In addition, in the related art, in doors for opening and closing a refrigerating chamber, a freezing chamber, a vegetable chamber, and the like, the door for opening and closing the refrigerating chamber is pivotally supported by a refrigerator main body by a hinge so as to be rotatable. A reinforcing plate is additionally provided to a door hinge attachment portion to improve the strength of the hinge attachment portion and prevent deformation of the hinge attachment portion and door drop (see, for example, patent document 3).
Fig. 36 and 37 show a door support structure of a refrigerator disclosed in patent document 3. As shown in fig. 36 and 37, in the conventional door support structure, a reinforcing plate 3604 is provided on the rear surface of a partition front plate 3603 to which the front surface of a partition wall 3602 of a hinge member 3601 is attached and fixed. A hinge member 3601 is fixed to the reinforcing plate 3604 with a screw 3605. With this structure, the load of the door 3606 is supported by the reinforcing plate 3604, and deformation of the partition front plate 3603 serving as the hinge attachment portion and door drop are reduced.
The reinforcing plate 3604 has both end portions 3604a fixed to the left and right end surfaces of the partition wall 3602 and is integrated with the partition wall 3602, thereby increasing the strength of the partition wall 3602 and the partition front plate 3603. In fig. 36, a heat insulating material 3607 is provided at the tip of a partition wall 3602.
However, as described above, in recent refrigerators, the front panel of the door is made of a glass plate, and the weight of the door is increased in view of increasing the quality.
Therefore, the load applied to the hinge attachment portion is also increased, and if the conventional structure in which the door load is supported only by fixing and integrating the reinforcement plate 3604 disposed on the rear surface of the partition front plate 3603 to the partition wall 3602, sufficient support strength is not obtained, and further strength improvement of the hinge attachment portion is strongly required.
As described above, in a refrigerator, a partition plate is generally provided in a refrigerator main body to form storage compartments such as a refrigerating compartment, a freezing compartment, and a vegetable compartment. For example, a partition plate that partitions a space between a refrigerating compartment and a freezing compartment is filled with foamed polyurethane in the same manner as a space between an inner box and an outer box constituting a refrigerator main body, and the partition plate has heat insulation properties (see, for example, patent document 4).
Fig. 38 shows a refrigerator described in patent document 4. The refrigerator shown in fig. 38 is divided into a refrigerating chamber 3802 and a freezing chamber 3803 in a refrigerator main body 3800 by an insulation partition plate 3801. The partition plate 3801 is filled with foamed polyurethane 3804 in a hollow portion between the upper surface plate 3801a and the lower surface plate 3801b thereof.
In the refrigerator described in patent document 4, the partition plate 3801 for heat insulation is filled with the foamed polyurethane 3804, and therefore, the heat insulation performance is high. Therefore, there are such advantages as follows: thinning the plate thickness of the partition plate 3801 without reducing the volumes of the refrigerating chamber 3802 and the freezing chamber 3803 can ensure the heat insulation property. In particular, since refrigerating chamber 3802 and freezing chamber 3803 have different cooling temperature ranges, if the present invention is applied to a partition plate that partitions between the two, the heat insulating effect is large.
However, since upper surface plate 3801a and lower surface plate 3801b of partition plate 3801 are made of polypropylene resin, the adhesion to foamed polyurethane 3804 is poor. Therefore, in this case, peeling occurs between partition plate 3801 and foamed polyurethane 3804, and a portion of partition plate 3801 having heat insulation properties, which becomes the bottom surface of the refrigerating compartment, of upper surface plate 3801a tends to be warped or the like.

Disclosure of Invention
An object of the present invention is to provide a refrigerator which can suppress deformation of a refrigerator main body having a large weight even in long-term use and does not lower reliability.
Specifically, a refrigerator according to an embodiment of the present invention includes: a refrigerator main body having a plurality of storage compartments; and a plurality of doors for opening and closing the storage chamber. The refrigerator main body includes an outer box, an inner box, and a foamed heat insulating material filled between the outer box and the inner box. The refrigerator main body further includes a plurality of side plate portions and a bottom plate portion. The storage chamber disposed at the lowermost portion of the refrigerator main body among the plurality of storage chambers has a corner portion as a connecting portion between each of the plurality of side plate portions and the bottom plate portion, and the corner portion has a 1 st thick-walled portion thicker than the wall of the refrigerator main body at the other portion than the corner portion on both the side plate portion side and the bottom plate portion side.
According to such a configuration, the rigidity of the refrigerator main body can be greatly improved at the lower end of the side plate portion of the refrigerator main body, which has a high proportion of bearing the entire weight of the refrigerator main body having a large weight, and the refrigerator main body can be prevented from being deformed even if the full load of the refrigerator main body and the door is continuously supported for a long period of time. Further, since the 1 st thick portion having a greater thickness than the other portions is provided at each corner portion of the side plate portion side and the bottom plate portion side of the lower portion of the refrigerator main body, deformation can be prevented without significantly reducing the capacity as compared with the case where the thickness of the entire wall around the storage compartment at the lowermost portion of the refrigerator main body is increased.
Thus, deformation of the refrigerator main body can be prevented for a long period of time without greatly reducing the capacity of the refrigerator main body. Therefore, the refrigerator can be provided with a large capacity and high reliability while maintaining reliability to the refrigerator.
In the refrigerator according to the embodiment of the present invention, one of the doors for opening and closing the plurality of storage compartments may be a left-right split door having a large door and a small door, and one of the left-right split doors may be formed to be larger than the other. In this case, the side plate portion of the refrigerator main body on the side where the large door is pivotally supported, among the plurality of side plate portions, has the 2 nd thick portion thicker than the side plate portion of the refrigerator main body on the side where the small door is pivotally supported. Further, a rectangular frame portion having a partition plate and a 2 nd thick portion located respectively at the upper and lower portions of the 2 nd thick portion on the side is arranged in the refrigerator main body.
With this structure, the strength of the side plate portion of the refrigerator main body to which the large cantilever moment load of the door is directly applied is increased by the 2 nd thick portion. Further, by disposing the rectangular frame portion having the 2 nd thick portion on one side in the refrigerator main body, the rigidity of the portion directly below the door pivot support of the refrigerator main body is improved, and even if the cantilever moment load of the door continues to be received, the cantilever moment load of the door can be resisted, and the deformation of the refrigerator main body can be suppressed. Therefore, even if the refrigerator is used for a long time, a step difference is not generated between the left and right doors of the left and right split doors, and the refrigerator with high reliability can be obtained.
In the refrigerator according to the embodiment of the present invention, the lowermost storage chamber of the refrigerator main body among the plurality of storage chambers has a corner portion as a connecting portion between the side plate portion and the bottom plate portion. The corner portion has a 1 st thick portion thicker than the wall of the refrigerator main body at the other portion except the corner portion on both the side plate portion side and the bottom plate portion side. One of the plurality of doors is formed of a left-right split door having a large door and a small door, and one of the left-right split doors is formed to be larger than the other. The side plate portion of the refrigerator main body on the side where the large door is pivotally supported, among the plurality of side plate portions, has a 2 nd thick portion thicker than the side plate portion of the refrigerator main body on the side where the small door is pivotally supported. In the refrigerator according to the embodiment of the present invention, a rectangular frame portion having a partition plate and a 2 nd thick portion on the side thereof is disposed in the refrigerator main body, the partition plate being positioned above and below the 2 nd thick portion, respectively.
According to this configuration, it is possible to provide a refrigerator having the above-described effect of the 1 st thick portion, the effect of the 2 nd thick portion, and the effect of the quadrangular frame portion. That is, the rigidity of the portion (the 2 nd thick portion) directly below the door support portion of the side plate portion of the refrigerator main body that supports the load of the door in a concentrated manner and the rigidity of the lower portion (the 1 st thick portion) of the refrigerator main body that has a high ratio of receiving the entire weight of the refrigerator main body are increased, and the entire refrigerator main body can be formed in a tough manner. Therefore, a refrigerator with less deformation of the refrigerator main body even if used for a long time and high reliability can be provided.
In the refrigerator according to the embodiment of the present invention, the rail of the container may be provided so as to be movable into and out of the storage compartment disposed at the lowermost part of the refrigerator main body at the step part of the side plate part formed by the 1 st thick-walled part having a thick wall at the corner part.
According to this configuration, the container can be set in a state of being lifted from the bottom surface of the storage compartment by the 1 st thick-walled portion, and the track setting can be rationalized. Further, even if dew condensation water is generated and accumulated on the bottom surface of the storage chamber, it is possible to prevent the rail from being immersed in the dew condensation water, or the dew condensation water attached to the rail from freezing, or the rail from rusting to cause malfunction, and it is possible to provide a refrigerator with higher reliability.
In the refrigerator according to the embodiment of the present invention, the step portion of the bottom plate portion formed by the 1 st thick portion having a thick corner wall may be inclined so that the upper surface thereof is lowered toward the front opening end portion of the storage chamber disposed at the lowermost portion of the refrigerator main body.
According to such a configuration, even if the container tends to sink due to the weight of the container when the container is pulled out, the bottom surface of the container can be prevented from being scraped against the upper surface of the stepped portion. That is, scratches, deterioration in appearance, and the like can be prevented from occurring in the portion facing the opening of the storage compartment.
In the refrigerator according to the embodiment of the present invention, the rectangular frame portion having the partition plate and the 2 nd thick portion arranged respectively at the upper and lower portions of the 2 nd thick portion may be divided into the left and right storage chambers by the vertical partition, and one of the left and right storage chambers may be formed to have a larger volume than the other storage chamber. The side plate part of the refrigerator main body, which is arranged at one side of the storage chamber with a large volume in the storage chamber divided into the left and the right, is provided with a 2 nd thick-walled part.
According to this configuration, the rectangular frame portion is divided into the left and right storage chambers by the vertical partition, and thus the rigidity of the rectangular frame portion itself can be further improved. At the same time, the strength of the storage chamber having a large volume and a large opening, which is likely to be weakened, can be increased by the 2 nd thick portion. Therefore, deformation of the refrigerator main body is further effectively suppressed, and the reliability of the refrigerator can be greatly improved.
In the refrigerator according to the embodiment of the present invention, the vacuum heat insulating material may be disposed in a part of the side plate portion of the refrigerator main body. In this case, the vacuum heat insulating material is disposed so that the lower end thereof does not overlap the 1 st thick-walled portion of the lower portion of the side plate portion, and the corner portions of the side plate portion and the bottom plate portion of the refrigerator main body are formed as heat insulating materials using only foamed heat insulating materials.
According to this configuration, only the foam heat insulating material having higher rigidity than the vacuum heat insulating material is filled in the corner portion between the side plate portion and the bottom plate portion of the refrigerator main body, and therefore the strength of the corner portion is higher than that in the case where the vacuum heat insulating material is inserted. Therefore, the refrigerator main body is strongly prevented from being deformed, and the reliability can be further improved.
The refrigerator according to the embodiment of the present invention may have a partition plate that partitions the interior of the refrigerator main body into a plurality of storage compartments, one of the plurality of storage compartments may be partitioned into right and left sides by a vertical partition plate, and the upper and lower partition plates of the storage compartment partitioned into right and left sides may be connected by the vertical partition plate.
According to this configuration, since the partition plate constituting the upper portion and the partition plate constituting the lower portion of the storage chamber partitioned into the left and right sides are connected by the vertical partition body, the torsion force applied to the storage chamber partitioned into the left and right sides is strengthened. Further, even if the storage chamber has a large lateral width, the lateral width in the lateral direction is divided and connected by the vertical partition, and the function of the storage chamber divided into the left and right as a strength member is improved. This can significantly improve the rigidity of the refrigerator even if the lateral width is large. Therefore, even if a torsional force or the like is applied to the refrigerator main body when the door is opened or closed, the door can resist the torsional force. At the same time, even if the door is made of a glass material or the like and has a large weight, the door can bear the weight of the door, and the deformation of the refrigerator main body can be strongly suppressed. In addition, even if the refrigerator main body is enlarged in the lateral width direction and the lateral width dimension of the upper partition plate and the lower partition plate of the storage compartment partitioned into left and right is enlarged, the upper partition plate and the lower partition plate are connected by the vertical partition plate at a part in the lateral width direction, so that the upper partition plate and the lower partition plate can be prevented from being deformed into a bulging shape. Thus, the flatness of the refrigerator main body can be improved, a high-quality refrigerator with high dimensional accuracy can be provided, the rigidity of the refrigerator main body can be improved, and a large-sized high-quality refrigerator can be provided.
In the refrigerator according to the embodiment of the present invention, the vertical partition may be integrally formed with at least one of the upper partition plate and the lower partition plate. The upper partition plate and the lower partition plate may be coupled by fitting (fitting method) of an engaging portion provided on the vertical partition body and an engaged portion.
According to this configuration, the partition plate can be connected to the upper partition plate and the lower partition plate only by fitting the engaging portion provided on the longitudinal partition body and the engaged portion, and the connection operation can be performed easily and quickly as compared with the case of performing screw fastening or the like. Further, since the longitudinal partition body is formed integrally with at least one of the upper partition plate and the lower partition plate, the number of parts can be reduced, and the working time can be shortened, and the longitudinal partition body can be provided at low cost.
In the refrigerator according to the embodiment of the present invention, the vertical partition may have an upper portion and a lower portion. In this case, the upper portion of the vertical partition may be formed integrally with the upper partition plate so as to protrude downward from the upper partition plate, and the lower portion of the vertical partition may be formed integrally with the lower partition plate so as to protrude upward from the lower partition plate. Further, a locking portion is provided on one of butt joint end surfaces of the upper portion of the vertical partition body and the lower portion of the vertical partition body, and a recess into which the locking portion is fitted is formed on the other.
According to this configuration, the upper partition plate and the lower partition plate can be connected only by fitting the engaging portion provided on one of the upper portion of the longitudinal partition body and the lower portion of the longitudinal partition body into the recess provided on the other, and the connecting operation can be performed easily and quickly as compared with the case of performing the screwing or the like. Further, since the upper portion of the vertical partition and the lower portion of the vertical partition are integrally formed with the partition plate of the upper portion and the partition plate of the lower portion, respectively, the number of parts can be reduced, and the operation time can be shortened, and the vertical partition can be provided at low cost.
In the refrigerator according to the embodiment of the present invention, the left and right storage chambers of the plurality of storage chambers may be formed to have a larger volume than the other storage chamber, the side plate portion of the refrigerator main body on the side where the storage chamber having a larger volume is disposed may be formed to have a larger wall thickness than the side plate portion of the refrigerator main body on the side where the storage chamber having a smaller volume is disposed.
With this configuration, the rigidity of the large storage compartment, which has a large opening and is likely to be weakened in strength, in the storage compartment divided into the left and right compartments can be increased by the thick side plate portions, and the rigidity of the refrigerator main body can be further increased.
In the refrigerator according to the embodiment of the present invention, the storage room located above the storage room partitioned into left and right sides may have left and right side-by-side doors, and one of the left and right side-by-side doors may be formed to be larger than the other and may have a large door and a small door. In the refrigerator according to the embodiment of the present invention, the storage compartment located on the side of the door having the large pivot support, among the storage compartments partitioned into the left and right sides, may have a larger volume than the storage compartment located on the side of the door having the small pivot support. In the refrigerator according to the embodiment of the present invention, the thickness of the side plate portion of the refrigerator main body on the side where the storage chamber having a large volume is disposed may be larger than the thickness of the side plate portion of the refrigerator main body on the side where the storage chamber having a small volume is disposed.
With this configuration, the storage chamber having a large volume among the left and right partitioned storage chambers is easily weakened due to a large opening, and the rigidity thereof is improved. At the same time, the strength of the side plate portion of the refrigerator main body of the portion to which the large cantilever moment load of the door is directly applied can be improved. Therefore, even if the door is formed of a glass door or the like, the refrigerator can be made heavier, and deformation of the refrigerator main body and the like can be effectively suppressed.
In addition, the refrigerator according to the embodiment of the present invention may be configured to firmly support the door while bearing a large weight even when the door is enlarged or made of glass (the door is made of a heavy material such as a glass plate) or the like.
Specifically, a refrigerator according to an embodiment of the present invention may include: a refrigerator main body; a partition plate for partitioning the inside of the refrigerator main body; a partition front plate covering a front surface of the partition plate; a hinge member disposed on a front surface of the partition front plate; and a reinforcing fitting disposed on the back surface of the partition front plate opposite to the hinge member. In this case, the hinge member is fixed to the partition front surface together with the partition and the reinforcement fitting. At the same time, the end of the reinforcement metal fitting extends to the front end face of the side plate of the refrigerator body, and the extension piece of the reinforcement metal fitting is fixed to the front end face of the side plate of the refrigerator body together with the end of the partition front plate.
According to this configuration, the reinforcing metal fitting for supporting the door load is integrated with the side plate portion of the refrigerator main body together with the partition plate, and supports the door load applied to the reinforcing metal fitting. In other words, the door load formed to be applied to the reinforcement fitting is supported by the side plate portion of the refrigerator main body together with the partition plate. Therefore, the strength of the hinge attachment portion can be greatly improved. That is, the strength of the hinge attachment portion can be greatly improved by the reinforcing effect of the hinge attachment portion and the extension piece portion of the reinforcing metal fitting fixed to the refrigerator main body side plate portion. Therefore, even if the door is heavy, deformation of the hinge attachment portion, door sagging, and the like can be effectively suppressed, and a refrigerator with high reliability can be provided.
In the refrigerator according to the embodiment of the present invention, a part of the hinge member may be fastened to the end portion of the partition front plate together with the extension piece of the reinforcement metal fitting at the front end surface of the side plate portion of the refrigerator main body.
According to such a configuration, the hinge member is also directly supported by the side plate portion of the refrigerator main body, and the door can be effectively prevented from drooping or the like by the support of both the refrigerator main body side plate portion and the partition plate.
In the refrigerator according to the embodiment of the present invention, the partition plate may have an upper partition plate cover and a lower partition plate cover, and these covers may be combined. In this case, the front panels of the upper partition plate cover and the lower partition plate cover, which constitute the front surface of the partition plate, are overlapped and fixed to each other.
With this configuration, the strength of the front surface of the partition plate itself to which the hinge member, the partition front plate, and the reinforcement fitting are fixed can be increased. Therefore, the strength of the hinge attachment portion can be further improved, and door sagging and the like can be more effectively prevented.
The refrigerator according to the embodiment of the present invention may be configured such that the interior of the partition plate is filled with a foamed heat insulating material.
With this structure, the strength of the partition plate itself is improved by the foamed heat insulating material, and the strength of the hinge attachment portion can be further improved.
In the refrigerator according to the embodiment of the present invention, the reinforcing member may be attached to the inner surface of the front panel of the partition plate, and the reinforcing member may be disposed so as to protrude into the foamed heat insulating material.
According to such a configuration, the strength of the front panel portion of the partition panel can be greatly increased by the reinforcing member protruding into the foamed heat insulating material. Therefore, the strength of the hinge attachment portion is greatly improved, and door sagging and the like can be more effectively prevented.
In addition, the refrigerator according to an embodiment of the present invention may include: the refrigerator includes a refrigerator main body, a partition plate forming a plurality of storage compartments in the refrigerator main body, and a door opening and closing the plurality of storage compartments. The partition plate may be configured such that a hollow portion inside the partition plate is filled with a foamed heat insulating material, and the partition plate has a surface plate on the inner surface of which a rib having a hook portion is provided, the rib being embedded in the foamed heat insulating material.
According to such a structure, the hook-shaped portions of the ribs provided on the inner surface of the surface plate of the partition plate are mechanically bonded to the foamed heat insulating material. Therefore, the separation of the surface plate of the partition plate from the foamed heat insulating material can be suppressed. This makes it possible to provide a high-quality refrigerator without floating deformation of the surface plate.
The refrigerator according to the embodiment of the present invention may be configured such that the refrigerator main body includes an inner box and an outer box, a foamed heat insulating material is filled between the inner box and the outer box, and polyurethane filling ports communicating with the space between the inner box and the outer box of the refrigerator main body are provided on the left and right sides of the front of the partition plate. Further, the refrigerator according to the embodiment of the present invention may have a plurality of ribs arranged in a direction intersecting the opening surface of the urethane filling port. Further, the rib may have a bridge shape.
According to such a configuration, the partition plate can be simultaneously filled with the foamed heat insulating material by filling the foamed heat insulating material into the refrigerator main body. Further, the foamed heat insulating material flowing into the partition plate from the urethane filling port can be more reliably caused to flow into and be cured between the inner surface of the surface plate of the partition plate and the bridge-shaped ribs. In the case where the ribs have a bridge shape, the hook-shaped portions of the mechanical structure of the foamed heat insulating material with the ribs are in the bridge shape, and therefore the foamed heat insulating material flowing into the partition plate from the urethane filling port has a structure in which the foamed heat insulating material is bonded to two portions at both ends of the bridge-shaped ribs. Therefore, the mechanical bonding of the foamed thermal insulation material to the bridge-shaped ribs becomes more reliable and powerful. Therefore, productivity can be improved by filling the refrigerator main body and the foamed heat insulating material of the partition plate at the same time, and peeling of the surface plate of the partition plate and the foamed heat insulating material can be prevented more reliably and strongly.
In the refrigerator according to the embodiment of the present invention, a plurality of ribs may be provided in a row at the front and rear portions of the partition plate, and the ribs may be configured such that the front-rear length of the ribs provided at the front portion is longer than the front-rear length of the ribs provided at the rear portion. Further, a plurality of ribs may be arranged in the left-right direction of the partition plate. In addition, the ribs may be configured to have a bridge shape.
According to this structure, the mechanical coupling of the surface plates of the partition plate at the front of the partition plate to the ribs is securely achieved over a wide range. Therefore, the separation of the front portion of the partition plate, which easily falls into the eyes of the user when the user opens the door, can be effectively prevented.
In the refrigerator according to the embodiment of the present invention, the door may be pivotally supported at both left and right ends of the partition plate, and a plurality of ribs may be provided on the inner surface of the front panel of the partition plate in the left-right direction, and the rib near the pivotally supporting portion of the door among the plurality of ribs may be provided on the front end surface portion of the partition plate rather than the other ribs.
According to this configuration, the mechanical coupling between the rib and the surface plates of the right and left partitions of the partition pivotally supporting the door is performed on the front end surface side close to the pivotally supporting portion of the door. Therefore, the peeling of the surface plate and the foamed heat insulating material near the pivot support portion of the door, which is likely to cause the peeling, can be more effectively suppressed.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to this embodiment.
(embodiment mode 1)
Fig. 1 is an external perspective view of a refrigerator according to embodiment 1 of the present invention, and fig. 2 is a schematic longitudinal sectional view of the refrigerator according to embodiment 1 of the present invention. The left side in fig. 2 is the front, and the right side is the rear. Fig. 3 is a front view showing the interior of the refrigerator according to embodiment 1 of the present invention, and fig. 4 is a perspective view showing the interior of the refrigerator according to embodiment 1 of the present invention.
In fig. 1 and 2, a refrigerator main body 101 of the refrigerator according to the present embodiment is configured by a metal outer box 102 having an opening at the front, an inner box 103 made of hard resin (e.g., ABS resin), and a foamed heat insulating material 104 such as hard foamed urethane filled between the outer box 102 and the inner box 103.
The refrigerator main body 101 is larger in size in the lateral width direction than the conventional refrigerator main body. The refrigerator main body 101 includes a plurality of storage compartments such as a refrigerating compartment 105, a switching compartment 106 (right side viewed from the front) located below the refrigerating compartment 105, an ice-making compartment 107 (left side viewed from the front) provided in parallel with the switching compartment 106, a freezing compartment 108 located below the switching compartment 106 and the ice-making compartment 107, and a vegetable compartment 109 located below the freezing compartment 108.
Of the plurality of storage compartments, refrigerating compartment 105 is provided with left and right side-by-side doors 110(110a, 110b) on its front surface, which are openable and closable as shown in fig. 1. The switching chamber 106, the ice making chamber 107, the freezing chamber 108, and the vegetable chamber 109 are provided with pull-out doors 111, 112, 113, and 114 on their front surface portions so as to be openable and closable.
The doors 110 to 114 are each formed by foaming and filling hard polyurethane inside, and have heat insulation properties, as in the refrigerator main body 101. In addition, a front plate such as a glass plate is attached to the front surface of each of the doors 110 to 114 in order to improve design. As shown in fig. 3 and 4, one side end upper and lower portions of door 110(110a, 110b) that is split left and right on the front surface of refrigerating room 105 are pivotally supported by hinge members 115 attached to left and right side plate portions 101a of refrigerator main body 101. One door 110a of the left and right split doors 110(110a, 110b) is larger in size than the other door 110 b. In the present embodiment, one door 110a is a larger door than the other door 110b, and the other door 110b is a smaller door.
On the other hand, as shown in fig. 2, a cooling chamber 116 is provided on the rear surface of the refrigerator main body 101, and a cooler 117 for generating cold air and a blower fan 118 for supplying the cold air to each chamber are provided inside the cooling chamber 116. A compressor 119 is provided in a deep portion of the top surface of the refrigerator main body 101. Compressor 119, a condenser (not shown), heat radiation pipe 120 for heat radiation provided on the back surface of refrigerator main body 101, capillary tube 120a, and cooler 117 in cooling chamber 116 are sequentially connected in a ring shape to constitute a refrigeration cycle. The refrigerant is sealed in the refrigeration cycle, and the compressor 119 performs a cooling operation.
Refrigerating compartment 105, switching compartment 106, and ice-making compartment 107, freezing compartment 108, and vegetable compartment 109 provided side by side are formed by partitioning the inside of refrigerator main body 101 in the vertical direction by partitions 121, 122, and 123.
The refrigerator main body 101 is provided with a vacuum heat insulating material 124 between the outer case 102 and the inner case 103. That is, as shown in fig. 2, a foam heat insulating material 104 and a vacuum heat insulating material 124 are provided between the outer casing 102 and the inner casing 103. As a result, the refrigerator main body 101 can be made thinner and have a larger capacity than a case where only the foamed heat insulating material 104 is used as a heat insulating material.
Fig. 5 is a schematic diagram for explaining the thickness of each part of the refrigerator main body of the refrigerator according to embodiment 1 of the present invention, and fig. 6 is a partial front view showing the main part of the refrigerator according to embodiment 1 of the present invention. Fig. 7 is a perspective view showing a lower portion of a refrigerator main body of a refrigerator according to embodiment 1 of the present invention, and fig. 8 is a side view showing a front end portion of a thick portion provided in the lower portion of the refrigerator main body of the refrigerator according to embodiment 1 of the present invention.
As shown in fig. 5, in refrigerator main body 101 according to the present embodiment, switching room 106 located below refrigerating room 105 and ice making room 107, freezing room 108, and vegetable room 109 provided side by side have thicknesses T2, T3, T4, and T5, respectively, set to be thicker than thickness T1 of refrigerating room 105. Among the lower wall thicknesses set to be thicker than wall thickness T1 of refrigerating room 105, wall thicknesses T2, T3, and T4 of switching room 106 and ice making room 107 and freezing room 108, respectively, which are located next to each other and have a lower cooling temperature range requiring strong heat insulation, are set to be thicker than wall thickness T5 of vegetable room 109, which is higher than the cooling temperature range.
As shown in fig. 7, the refrigerator main body 101 of the present embodiment has a (1 st) thick portion 126(126a, 126b) that is thicker than a flat portion Y other than the corner X on both the side plate portion 101a side and the bottom plate portion 101b side at the corner X of the connection portion between the side plate portion 101a and the bottom plate portion 101b of the vegetable compartment 109 serving as the lowermost storage compartment of the refrigerator main body 101. That is, the 1 st thick portion 126 is composed of the thick portion 126a on the side plate portion 101a side of the corner portion X and the thick portion 126b of the bottom plate portion 101b of the corner portion X.
Further, in the refrigerator main body 101 of the present embodiment, the thickness T2 of the side plate portion 101a of the refrigerator main body 101 on the side of the larger door 110a out of the left and right side-by- side doors 110a and 110b pivotally supported by the refrigerating room 105 having a large proportion of the total load of the refrigerator main body 101 is set to be thicker than the thickness T3 of the side plate portion 101a of the refrigerator main body 101 on the side of the pivotally supported smaller door 110b (T2 > T3). That is, in the present embodiment, the side plate portion 101a on the side of the door 110a having the larger pivot support has the (2 nd) thick portion 127a (see fig. 5) whose wall thickness is thicker than the thick portion 127b of the side plate portion 101a on the side of the door 110b having the smaller pivot support. Therefore, in the present embodiment, the thicknesses T1, T2, T3, T4, and T5 of the refrigerator main body 101 have a relationship of T2 > T3 ═ T4 > T5 > T1.
As shown by the broken lines in fig. 5, in the present embodiment, the inside of refrigerator main body 101 is partitioned by partition plates 121 and 122 above and below thick portion 127, thereby forming rectangular frame portion R having (2 nd) thick portion 127a on one side in refrigerator main body 101. That is, the rectangular frame portion R has (2 nd) thick portion 127a on the side, and partition plates 121 and 122 respectively disposed above and below (2 nd) thick portion 127a, and is disposed in the refrigerator main body 101. More specifically, the rectangular frame portion R is configured with a (2 nd) thick portion 127a, partition plates 121 and 122 disposed above and below the (2 nd) thick portion 127a, and a thick portion 127b provided at a position facing the (2 nd) thick portion 127a as one side, and is disposed in the refrigerator main body 101. As shown in fig. 5 and 6, the rectangular frame portion R is provided with a vertical partition 125 between the partition plates 121 and 122, and is divided into two storage compartments, i.e., an ice storage compartment 107 and a switching compartment 106. A (2 nd) thick portion 127a is formed in the side plate 101a on the switching chamber 106 side having a large opening.
As shown in fig. 7, in the present embodiment, a fixed rail 130 is provided at a step 128 ( step 128a, 128b) formed by (1 st) thick portions 126a, 126b provided from a side plate portion 101a of a vegetable compartment 109 serving as a lowermost storage compartment of the refrigerator main body 101 to a bottom plate portion 101 b. The container (not shown) is provided on the side of the moving rail 129 that moves on the fixed rail 130. Therefore, the container is accommodated in the vegetable room 109 so as to be freely movable in and out through the moving rail 129 that moves on the fixed rail 130. As shown in fig. 8, the upper surface of the stepped portion 128b is formed to be inclined with respect to the horizontal surface so as to be lowered toward the front opening end of the vegetable compartment 109.
Fig. 9 is a perspective view showing the inside of a door pivot support portion of a refrigerator according to embodiment 1 of the present invention, and fig. 10 is a front view showing the door pivot support portion of the refrigerator according to embodiment 1 of the present invention.
As shown in fig. 9, in the refrigerator 100 of the present embodiment, a reinforcing metal fitting 131 is provided at an end portion of a front surface of a partition plate 121 to which a hinge member 115 that pivotally supports a large door 110a of a refrigerator main body 101 is attached. In addition, the end 131a of the reinforcing fitting 131 is extended to the front surface of the side plate portion 101 a.
The reinforcement fitting 131 is screwed to the inner surface side of the front end surface of the outer box 102 together with a partition front surface decorative fitting 132 (see fig. 10) provided on the front surface thereof for reinforcement. Further, the hinge member 115 is fixed to the front surface of the partition plate 121 with screws together with the partition plate front surface decorative fitting 132.
Fig. 11 is an exploded perspective view of the lower part of the refrigerator main body of the refrigerator according to embodiment 1 of the present invention. As shown in fig. 11, the refrigerator main body 101 of the refrigerator 100 according to the present embodiment is attached with a lower end reinforcing metal fitting 133 to the lower end of the side plate portion 101 a. A reinforcing beam 134 is disposed at the front end portion of the left and right side plate portions 101a, and the reinforcing beam 134 is fixed to the lower end reinforcing metal fitting 133 by screws or the like.
With such a configuration, the refrigerator 100 according to the present embodiment has increased rigidity by the connection of the side plate 101a, the lower end reinforcing fitting 133, and the reinforcing beam 134.
The lower end reinforcing metal fitting 133 has a shape covering, for example, the lower end surface of the side plate portion 101a, the lower portions of the front end surface and the rear end surface, the front portion, the bottom portion, and the rear portion of the outer surface of the side plate portion 101a, the left and right lower end surfaces of the back plate portion 101c, and the lower portions of the left and right outer surfaces of the back plate portion 101c in the present embodiment, but is not limited thereto. The shape does not necessarily cover the entire area, and may be a shape that enhances the rigidity of the refrigerator by connecting the side plate 101a and the reinforcing beam 134.
The operation and action of the refrigerator 100 of the present embodiment configured as described above will be described below.
First, in the refrigerator 100 of the present embodiment, the (1 st) thick portion 126 is provided at the corner X of the connection portion between the side plate portion 101a and the bottom plate portion 101b of the vegetable compartment 109 at the lowermost portion of the refrigerator main body 101. The (1 st) thick portion 126 of the corner portion X is constituted by the (1 st) thick portion 126a on the side plate portion 101a side of the corner portion X and the (1 st) thick portion 126b on the bottom plate portion 101b side of the corner portion X. The (1 st) thick portion 126 is formed such that both the (1 st) thick portion 126a on the side plate portion 101a side and the (1 st) thick portion 126b on the bottom plate portion 101b side are thicker than the wall thickness of the other portion than the corner portion X of the refrigerator main body 101. With this configuration, the lower end of the side plate 101a of the refrigerator main body 101, which receives a high proportion of the total weight of the refrigerator main body 101, has a significantly increased rigidity due to the (1 st) thick portion 126(126a, 126 b). This prevents the refrigerator main body 101 from being deformed even if the full load of the refrigerator main body 101 and the door 110(110a, 110b) having a large weight is continuously supported for a long period of time. Furthermore, since the (1 st) thick portion 126 for improving the rigidity of the refrigerator main body 101 is formed only at the corner X which is the connection portion between the side plate portion 101a and the bottom plate portion 101b in the lower portion of the refrigerator main body 101, it is possible to prevent deformation of the refrigerator main body 101 without significantly reducing the capacity, as compared with the case where the entire wall thickness around the vegetable compartment 109 in the lowermost portion of the refrigerator main body 101 is set to be thick.
In particular, in the refrigerator main body 101 of the refrigerator 100 according to the present embodiment, the (1 st) thick portion 126b is provided not only on the side plate portion 101a side but also on the bottom plate portion 101b side, and thus the (1 st) thick portion 126b functions as a strength member for a moment load in a twisting direction applied to the corner portion X, which is a connection portion between the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 when the door 110a is opened and closed. Therefore, as compared with the case where only the (1 st) thick portion 126a is provided in the side plate portion 101a, the resistance against the load of the refrigerator main body 101 and the door 110(110a, 110b) is improved, and the deformation of the refrigerator main body 101 can be more effectively prevented.
As described above, in the refrigerator 100 of the present embodiment, both capacity securing of the refrigerator main body 101 and prevention of deformation can be achieved at a high level.
In the refrigerator 100 of the present embodiment, the side plate 101a on the side of the door 110a on which the large door 110a is pivotally supported, among the side plates 101a pivotally supporting the left and right side-by-side doors 110(110a, 110b) of the refrigerator main body 101, may have a (2 nd) thick portion 127 thicker than the side plate 101a on the side of the door 110b on which the other small door is pivotally supported.
In the refrigerator 100 of the present embodiment, the refrigerator main body 101 is formed with a rectangular frame portion R having a thick (2 nd) thick portion 127a formed to have a large thickness on one side. Specifically, the rectangular frame portion R is constituted by a (2 nd) thick portion 127a, partition plates 121 and 122 provided above and below the (2 nd) thick portion 127a, and a thick portion 127b provided at a position facing the (2 nd) thick portion 127 a.
With such a configuration, even when the door 110(110a, 110b) is made of a glass plate or the like and has a heavy weight, the door 110(110a, 110b) can resist the moment load of the cantilever (particularly, on the larger door 110a side) of the door 110 and can resist deformation.
That is, by forming the side plate portion 101a on the side of the door 110a having the larger pivot support to be thick, the strength of the portion of the side plate portion 101a to which the cantilever moment load of the door 110a is directly applied can be increased. This makes it possible to obtain a strength balance with the side plate portion 101a on the side of the door 110b having a smaller pivot support, and to resist deformation that is likely to occur due to a difference in the left and right door moment loads in a well-balanced manner. Further, the rectangular frame portion R having the (2 nd) thick portion 127a on one side is disposed in the portion directly below the door pivot support, and the rigidity of the portion directly below the door pivot support of the refrigerator main body 101 can be improved. Accordingly, even if the cantilever moment load of the door 110(110a, 110b) continues to be received, the cantilever moment load of the door 110(110a, 110b) can be resisted, and deformation of the refrigerator main body 101 can be suppressed.
Therefore, even after long-term use, deformation of the portion directly below the door pivot support of the refrigerator main body 101 can be prevented, and for example, a step difference between the left and right doors 110a and 110b of the left and right half doors 110 can be eliminated, and a refrigerator with high reliability can be provided.
In the refrigerator 100 of the present embodiment, as described above, the (1 st) thick portion 126(126a, 126b) is formed at the corner X which is the connection portion between the side plate portion 101a and the bottom plate portion 101 b. In the refrigerator 100 of the present embodiment, the (2 nd) thick portion 127a having a thicker wall thickness than other portions may be provided in the side plate portion 101a of the door pivot supporting portion, and the rectangular frame portion R having the (2 nd) thick portion 127a on one side may be provided.
With such a configuration, the rigidity of each of the lower portion of the refrigerator main body 101, which has a high ratio of receiving the entire weight of the refrigerator main body 101, and the portion immediately below the door support portion, which intensively supports the load of the door 110, can be increased, and the entire refrigerator main body 101 can be made more rigid. Thus, a refrigerator with less deformation and high reliability can be obtained even after long-term use.
In the refrigerator 100 of the present embodiment, a container fixing rail 130 that can be freely inserted into and removed from the vegetable compartment 109 may be provided at the stepped portion 128(128a, 128b) of the side plate portion 101a formed at the corner X of the lowermost portion of the refrigerator main body 101. With this configuration, the fixed rail 130 is a strength member of the side plate 101a, and the rigidity can be further improved. Further, the (1 st) thick portion 126(126a, 126b) provided to increase the rigidity of the refrigerator main body 101 allows the container to be set in a state of being raised from the bottom surface of the vegetable compartment 109, and thus the track setting can be rationalized.
In the refrigerator 100 of the present embodiment, the fixed rail 130 and the moving rail 129 may be provided in the step portion 128(128a, 128 b). According to such a configuration, even when dew condensation water is generated on the bottom surface of vegetable compartment 109 and dew condensation water is accumulated, dew condensation water adhering to fixed rail 130 and moving rail 129 due to the immersion of fixed rail 130 and moving rail 129 in dew condensation water can be prevented from freezing, and rust due to the adhesion of dew condensation water can be prevented from being generated. Therefore, a refrigerator with high reliability in which malfunction of the rails is avoided is obtained.
In the refrigerator 100 of the present embodiment, the upper surface of the step portion 128b formed in the (1 st) thick portion 126b is formed to be inclined so as to be lowered toward the front opening end of the vegetable compartment 109 with respect to the horizontal plane. With this configuration, even if the container tends to fall due to its weight when the container is pulled out, the bottom surface of the moving rail 129 can be prevented from being scraped by the step 128 b. Therefore, scratches can be prevented from occurring in the portion facing the opening of vegetable compartment 109, which can prevent the appearance from deteriorating.
On the other hand, the rectangular frame portion R disposed at the portion directly below the door pivot support of the refrigerator main body 101 is divided into the switching chamber 106 and the ice making chamber 107 by the vertical partition 125. With this configuration, the rigidity of the rectangular frame portion R itself can be improved, and deformation of the portion immediately below the door pivot support can be effectively prevented. The (2 nd) thick portion 127a formed in the portion directly below the door pivot support is formed in the side plate portion 101a on the switching chamber 106 side having a wide opening. With this configuration, the opening strength of the switching room 106, which is likely to be weakened in the opening width strength, can be increased, and deformation of the refrigerator main body 101 can be more effectively suppressed.
In the refrigerator 100 of the present embodiment, the vacuum heat insulator 124 provided in the side plate portion 101a of the refrigerator main body 101 is provided to a position not overlapping with the (1 st) thick portion 126a in the lower portion of the side plate portion 101 a. The corner X between the side plate 101a and the bottom plate 101b of the refrigerator main body 101 is formed of only the foamed heat insulating material 104 as a heat insulating material. That is, the corner X between the side plate 101a and the bottom plate 101b of the refrigerator main body 101 is configured by filling only the foamed heat insulating material 104 having a higher strength than the vacuum heat insulating material 124 (i.e., without the vacuum heat insulating material) as a heat insulating material. With this configuration, the strength of the corner portion X is higher than that in the case where the vacuum heat insulating material 124 is inserted, and thus deformation of the refrigerator main body 101 can be prevented strongly, and a refrigerator with higher reliability can be obtained.
The refrigerator 100 of the present embodiment has at least one of the following features. One is a structure in which a (1 st) thick portion 126(126a, 126b) is formed at a corner X which is a connection portion between the side plate portion 101a and the bottom plate portion 101 b. The other is a structure in which a (2 nd) thick portion 127a having a large thickness is formed in the side plate portion 101a of the door pivot supporting portion. Further, the refrigerator main body 101 has a structure in which a rectangular frame portion R having a (2 nd) thick portion 127a as one side is disposed. The refrigerator 100 of the present embodiment is an example having both of these structures, but may have only one of these structures or may be configured by combining some of these structures. With either of these structures alone or a combination of some of these structures, the rigidity of the refrigerator main body 101 can be improved.
As described above, the refrigerator 100 of the present embodiment includes the refrigerator main body 101, the plurality of storage compartments 105, 106, 107, 108, and 109, and the plurality of doors 110, 111, 112, 113, and 114 that open and close the plurality of storage compartments 105, 106, 107, 108, and 109. The refrigerator main body 101 includes an outer box 102, an inner box 103, and a foamed heat insulating material 104 filled between the outer box 102 and the inner box 103.
In the refrigerator 100 of the present embodiment, the corner X of the connection portion between the side plate 101a and the bottom plate 101b of the storage compartment 109, which is the lowermost part of the refrigerator main body 101, has the 1 st thick portion 126, which is thicker than the wall thickness of the other portion than the corner X, at both the corner X of the side plate 101a and the corner X of the bottom plate 101 b.
With this configuration, the rigidity of the lower end of the side plate portion 101a of the refrigerator main body 101, which has a high percentage of bearing the entire weight of the refrigerator main body 101 having a large weight, can be greatly improved. Thus, the lower end of the side plate 101a of the refrigerator main body 101 can be prevented from being deformed even if the weight of the refrigerator main body 101 and the doors 110, 111, 112, 113, and 114 is continuously supported for a long period of time. Further, since the wall thickness of the corner X, which is the connection portion between the side plate portion 101a and the bottom plate portion 101b of the storage chamber 109 at the lowermost portion of the refrigerator main body 101, is set to be thicker than the respective corner X of the side plate portion 101a and the bottom plate portion 101b at the lower portion of the refrigerator main body 101, deformation prevention can be achieved without significantly reducing the capacity of the refrigerator 100 as compared with the case where the wall thickness of the entire periphery of the storage chamber 109 at the lowermost portion of the refrigerator main body 101 is set to be thick.
One of the doors 110, 111, 112, 113, and 114 of the refrigerator 100 according to the present embodiment is configured by the left and right half doors 110, and one of the left and right half doors 110 has a door 110a larger than the other. In this case, the side plate 101a of the refrigerator main body 101 on the side pivotally supporting the large door 110a preferably has the 2 nd thick portion 127a having a larger wall thickness than the wall thickness of the side plate 101a of the refrigerator main body 101 on the side pivotally supporting the other small door 101 b.
In refrigerator 100 of the present embodiment, partition plates 121 and 122 arranged above and below 2 nd thick portion 127 and rectangular frame portion R having 2 nd thick portion 127a are arranged on the sides in refrigerator main body 101, and preferably arranged below refrigerating room 105 having large door 110 a.
With this configuration, the strength of the side plate 101a of the refrigerator main body 101 to which the large cantilever moment load of the door 110a is directly applied is increased by the 2 nd thick portion 127 a. Further, by disposing the rectangular frame portion R having the 2 nd thick portion 127a as one side on the refrigerator main body 101, the rigidity of the portion directly below the pivot support of the door 110 of the refrigerator main body 101 is improved. Thus, even if the side plate portion 101a of the refrigerator main body 101 continues to receive a large cantilever moment load of the door 110a of the door 110, the cantilever moment load of the door 110 can be resisted, and deformation of the refrigerator main body 101 can be suppressed. Therefore, even if the refrigerator is used for a long period of time, a step difference is not generated between the left and right side doors of the left and right split doors 110, and a refrigerator with high reliability is obtained.
In the refrigerator 100 of the present embodiment, the corner X of the connection portion between the side plate 101a and the bottom plate 101b of the storage compartment 109, which is the lowermost part of the refrigerator main body 101, has the 1 st thick-walled portion 126, which is thicker than the walls of the other portions other than the corner X, at both the corner X of the side plate 101a and the corner X of the bottom plate 101b, and one of the doors 110, 111, 112, 113, and 114 is formed by the left and right half doors 110. In this case, one of the left and right split doors 110 has a door 110a larger than the other, and the other has a smaller door 110 b. In this case, the side plate 101a on the side of the large door 110a has the 2 nd thick portion 127a having a large wall thickness for pivotally supporting the side plate 101a on the side of the other small door 101 b. Partition plates 121 and 122 arranged above and below 2 nd thick portion 127a and a rectangular frame portion R of 2 nd thick portion 127a are provided on the sides, and are arranged in refrigerator main body 101.
According to such a configuration, the effect of having the above-described 1 st thick portion 126 and the effect of having the 2 nd thick portion 127a are combined, and the rigidity of each of the portion immediately below the support portion of the door 110 that intensively supports the load of the door 110 and the lower portion of the refrigerator main body 101 that has a high ratio of receiving the entire weight of the refrigerator main body 101 can be improved. This makes the entire refrigerator main body 101 tougher, and enables a highly reliable refrigerator with little deformation even after long-term use.
In the refrigerator 100 of the present embodiment, the container movement rail 129 provided in the storage compartment 109 so as to be movable in and out is provided in the step portion 128 of the side plate portion 101a formed by the 1 st thick portion 126 having a thick corner X.
According to such a configuration, since the container can be set in a state of being lifted from the bottom surface of the storage chamber 109 by the 1 st thick portion 126, the setting of the moving rail 129 can be rationalized. Even if dew condensation water is generated on the bottom surface of the storage chamber 109, it is possible to prevent dew condensation water adhering to the travel rail 129 due to the travel rail 129 being immersed in the dew condensation water from freezing, or prevent the travel rail 129 from rusting and causing malfunction. Therefore, a refrigerator with higher reliability can be obtained.
In the refrigerator 100 of the present embodiment, the upper surface (step 128a) of the step 128 of the bottom plate 101b formed by the 1 st thick portion 126 having a thick wall at the corner X is formed to be inclined so as to be lowered toward the opening end of the storage compartment 109 with respect to the horizontal plane.
According to such a configuration, even if the container tends to fall due to the weight of the container when the container is pulled out, the bottom surface of the container can be prevented from being scraped against the upper surface of the stepped portion 128. Therefore, scratches, deterioration in appearance, and the like can be prevented from occurring in the portion facing the opening of the storage compartment 109.
In the refrigerator 100 of the present embodiment, the rectangular frame portion R is divided into the left and right storage chambers 106 and 107 by the vertical partition 125, and the side plate portion 101a of the refrigerator main body 101 on the storage chamber 106 side having a wide opening out of the divided storage chambers has the 2 nd thick portion 127 a.
According to such a configuration, the rigidity of the rectangular frame portion R itself can be further improved by dividing the rectangular frame portion R into two storage chambers 106 and 107. At the same time, the opening strength of the storage chamber 106, which has a wide opening and is easily weakened, can be increased. This can further effectively suppress deformation of the refrigerator main body 101, and can significantly improve reliability.
In the refrigerator 100 of the present embodiment, the vacuum heat insulating material 124 is disposed on at least the side plate portion 101a of the refrigerator main body 101, the lower end of the vacuum heat insulating material 124 does not overlap the 1 st thick-walled portion 126 of the lower portion of the side plate portion 101a, and the corner portion X of the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 is configured using only the foamed heat insulating material 104 as the heat insulating material.
With this configuration, the corner X between the side plate 101a and the bottom plate 101b of the refrigerator main body 101 is filled with only the foamed heat insulating material 104 having a higher strength than the vacuum heat insulating material 124 as a heat insulating material, and therefore has a higher strength than the case where the vacuum heat insulating material 124 is inserted. Therefore, deformation of the refrigerator main body 101 is strongly prevented, and reliability can be further improved.
(embodiment mode 2)
The refrigerator 100 according to embodiment 2 of the present disclosure has a basic configuration similar to that of the refrigerator 100 according to embodiment 1 described above. Therefore, the same reference numerals are used and referred to for the same structure as that of embodiment 1, and the description thereof will be omitted.

Fig. 13 is an exploded perspective view of a vertical partition section integrated with a top partition plate and a bottom partition plate of a refrigerator according to embodiment 2 of the present invention.
The switching chamber 106 and the ice making chamber 107 provided in parallel with the switching chamber 106 in the refrigerator 100 according to the present embodiment are divided into left and right sections by a vertical partition body 125 provided in the vicinity of the front opening and a partition plate (not shown) provided behind the vertical partition body. In the present embodiment, as shown in fig. 12 and 13, the longitudinal partition body 125 is composed of a longitudinal partition body upper portion 125a and a longitudinal partition body lower portion 125 b. The vertical partition body upper part 125a is integrally formed with the upper partition plate 121 so as to protrude downward from the partition plate 121, and the upper partition plate 121 partitions the switching chamber 106 and the ice making chamber 107 (see fig. 1 to 6) provided in parallel with the switching chamber from the other storage chamber (in the present embodiment, the refrigerating chamber 105). Vertical partition lower portion 125b is integrally formed with lower partition plate 122 projecting upward from partition plate 122, and lower partition plate 122 partitions switching room 106 and ice making room 107 provided side by side from the other storage room (freezing room 108 in the present embodiment).
Fig. 14 is an enlarged perspective view of the vertical partition portion of the refrigerator main body of the refrigerator according to embodiment 2 of the present invention. Fig. 15A is a sectional view of the vertical partition of the refrigerator main body of the refrigerator according to embodiment 2 of the present invention as viewed from the front, and fig. 15B is a sectional view of the vertical partition of the refrigerator main body of the refrigerator according to embodiment 2 of the present invention as viewed from the side.
As shown in fig. 14, 15A, and 15B, a click portion 225 serving as an engagement portion and a recess 226 serving as an engaged portion into which the click portion 225 is fitted are formed on abutting end surfaces of the vertical partition body upper portion 125A and the vertical partition body lower portion 125B. The locking portion 225 is fitted into the recess 226, and the vertical partition body upper portion 125a and the vertical partition body lower portion 125b are integrally connected. In the present embodiment, the engaging portion 225 is formed on the end surface of the vertical partition body lower portion 125b, the recess 226 is formed on the end surface of the vertical partition body upper portion 125a, the engaging portion 225 is fitted into the recess 226, and the vertical partition body upper portion 125a and the vertical partition body lower portion 125b are integrally connected.
The vertical partition body upper part 125a and the vertical partition body lower part 125b are connected as follows. First, as shown in fig. 12, the upper partition plate 121 is configured by combining an upper plate 121a positioned above the upper partition plate 121 and a lower plate 121b positioned below the lower partition plate 121. Next, partition plate 121 is inserted into inner box 103 of refrigerator main body 101 from the front of refrigerator main body 101, and assembled. Then, lower partition plate 122 is inserted into inner box 103 from the front and assembled below partition plate 121 of refrigerator main body 101.
As a result, as shown by the arrows in fig. 14, the latching portion 225 of the vertical partition body lower portion 125B formed integrally with the lower partition plate 122 is fitted into the recessed portion 226 of the vertical partition body upper portion 125A formed integrally with the upper partition plate 121, and the vertical partition body upper portion 125A and the vertical partition body lower portion 125B are coupled to each other as shown in fig. 15A and 15B.
In this way, in a state where upper partition plate 121 and lower partition plate 122 are incorporated in refrigerator main body 101, foamed heat insulating material 104 is filled between inner box 103 and outer box 102 of refrigerator main body 101. Accordingly, foamed heat insulating material 104 is filled between inner box 103 and outer box 102 of refrigerator main body 101, and filled between upper plate 121a and lower plate 121b of upper partition plate 121 and inside lower partition plate 122, and upper partition plate 121 and lower partition plate 122 are formed integrally with refrigerator main body 101. Further, as shown in fig. 14, the front surfaces of the longitudinal partition body upper part 125a and the longitudinal partition body lower part 125b coupled as described above are covered with a decorative cover 227. The decorative cover 227 is fixed to the front surfaces of the upper partition plate 121 and the lower partition plate 122 with screws or the like.
As shown in fig. 12, a sweat-proof heat source mounting plate 228 is mounted on the front surface of the upper partition plate 121. The front surface of the sweat-proof heat source mounting plate 228 may be covered with a top separator plate reinforcing/decorating cover 229. In this case, the hinge members 115 are fixed to both left and right ends of the top partition plate reinforcing/decorating cover 229 with screws or the like together with the reinforcing metal fittings 230 disposed between the sweat-proof heat source mounting plate 228 and the top partition plate reinforcing/decorating cover 229. Door 110(110a, 110b) of the refrigerating compartment formed above partition plate 121 on the upper side is pivotally supported by hinge member 115 configured as described above.
In the refrigerator 100 of the present embodiment, the upper partition plate 121 and the lower partition plate 122 are connected to the refrigerator main body 101 by the vertical partition body 125, and the switching chamber 106 formed by the upper partition plate 121 and the lower partition plate 122 is formed to have a larger volume than the ice making chamber 107 provided in parallel with the switching chamber 106, as shown in fig. 5. The side plate portion on the switching chamber 106 side, which has a large capacity and a large opening, has a (2 nd) thick portion 127a whose thickness is set to be thicker than the side plate portion on the ice making chamber 107 side.
In addition, of the doors 110 for opening and closing the refrigerating chamber 105 disposed above the ice making chamber 107 and the switching chamber 106, the door 110a disposed at the upper portion of the switching chamber 106 having a large opening is larger than the door 110b disposed at the upper portion of the ice making chamber 107. The (2 nd) thick portion 127a is provided on one side plate portion of the large door 110 a.
Further, as shown in fig. 1 and 5, the refrigerator main body 101 of the present embodiment is provided with a vacuum heat insulator 124 between the outer box 102 and the inner box 103 constituting the refrigerator main body. By using the vacuum heat insulating material 124 and the foamed heat insulating material 104 in combination, the entire wall thickness of the refrigerator main body 101 can be made thinner and the capacity can be increased as compared with the case of using only the foamed heat insulating material 104.
As shown in fig. 5, the refrigerator main body 101 of the present embodiment has thicknesses T2, T3, T4, and T5 of the switching chamber 106 disposed below the refrigerating chamber 105 and the ice making chamber 107, the freezing chamber 108, and the vegetable chamber 109 disposed side by side, respectively, which are set to be thicker than the thickness T1 of the refrigerating chamber 105. In the storage compartment disposed below refrigerating compartment 105 and having a thickness set larger than thickness T1 of refrigerating compartment 105, thicknesses T2, T3, and T4 of switching compartment 106 having a low cooling temperature range, ice making compartment 107 disposed side by side, and freezing compartment 108, which require strong heat insulation, are preferably set larger than thickness T5 of vegetable compartment 109 having a high cooling temperature range. In the present embodiment, the wall thicknesses T1, T2, T3, T4, and T5 of the refrigerator main body 101 have the relationship of T2 > T3 ═ T4 > T5 > T1.
In the refrigerator main body 101 of the present embodiment, as shown in fig. 5, a corner X of a connecting portion between the side plate portion 101a and the bottom plate portion 101b of the vegetable compartment 109, which is a storage compartment disposed at the lowermost part of the refrigerator main body 101, has a (1 st) thick portion 126 having a wall thickness larger than that of the wall other than the corner X at both the corner X of the side plate portion 101a and the corner X of the bottom plate portion 101 b.
The operation and action of the refrigerator 100 configured as described above will be described below.
In refrigerator 100 of the present embodiment, ice making compartment 107 and switching compartment 106 partitioned into two compartments, i.e., left and right, are disposed in a substantially central portion in the vertical direction between refrigerating compartment 105 and freezing compartment 108 of refrigerator main body 101. Further, partition plate 121 on the upper side and partition plate 122 on the lower side constituting ice making chamber 107 and switching chamber 106 are connected by vertical partition body 125. With this configuration, the upper partition plate 121 and the lower partition plate 122 are coupled to each other by the longitudinal partition bodies 125, thereby reinforcing the torsional force. Further, even if refrigerator main body 101 is enlarged in the lateral width direction and the lateral width dimensions of partition plate 121 on the upper side and partition plate 122 on the lower side constituting ice making compartment 107 and switching compartment 106 are increased, the lateral width in the lateral direction is finely divided and connected by vertical partition body 125, so that the function as a strength member of the storage compartment (ice making compartment 107 and switching compartment 106) having upper partition plate 121 and lower partition plate 122 is improved. This can greatly improve the rigidity of the refrigerator main body 101.
Therefore, even if a twisting force or the like is applied to the refrigerator main body 101 when the door 110, particularly the large door 110a, is opened or closed, the door 110 can resist the twisting force or the like, and the deformation of the refrigerator main body 101 can be strongly suppressed by the large weight of the door 110(110a, 110b) formed of a heavy material such as a glass plate.
Even if the refrigerator main body 101 is increased in size in the lateral width direction and the lateral width dimensions of the upper partition plate 121 and the lower partition plate 122 are increased, the upper partition plate 121 and the lower partition plate 122 are connected by the vertical partition body 125 in the lateral width direction, and therefore, the upper partition plate 121 and the lower partition plate 122 can be prevented from being deformed into a bulging shape. Further, the flatness of upper partition plate 121 and lower partition plate 122 is improved, and a high-quality refrigerator with high dimensional accuracy can be obtained.
The upper partition plate 121 and the lower partition plate 122 are easily deformed particularly at the time of resin molding. For example, the upper partition plate 121 may be deformed upward and the lower partition plate 122 may be deformed downward, and the upper partition plate 121 and the lower partition plate 122 may be formed in a bulging shape (for example, a state in which a central portion in the left-right direction bulges out more than left and right end portions).
However, in the present embodiment, since the deformation of the upper partition plate 121 and the lower partition plate 122, which are formed in the bulging shape, is corrected by the connection between the vertical partition upper part 125a and the vertical partition lower part 125b, the flatness of the upper partition plate 121 and the lower partition plate 122 is improved, and the dimensional accuracy can be improved.
In the present embodiment, the upper partition plate 121 and the lower partition plate 122 are coupled by fitting the engaging portion 225 of the vertical partition body lower portion 125b into the recess 226 provided in the vertical partition body upper portion 125 a. Therefore, compared to the case where the vertical partition body upper part 125a and the vertical partition body lower part 125b are screwed and connected, the connection work can be performed easily and quickly, and the productivity can be improved.
The vertical partition body upper part 125a constituting the vertical partition body 125 is formed integrally with the upper partition plate 121, and the vertical partition body lower part 125b is formed integrally with the lower partition plate 122. Therefore, the number of components can be reduced, and the productivity can be improved by shortening the working time, and the refrigerator can be provided at low cost.
Further, since the vertical partition body 125 is formed by dividing the vertical partition body upper portion 125a and the vertical partition body lower portion 125b, the vertical dimension of at least one of the vertical partition body upper portion 125a and the vertical partition body lower portion 125b can be shortened. Therefore, deformation of the vertical division bodies 125, which is likely to occur when the vertical division bodies 125 are provided on the upper division plate 121 and the lower division plate 122, can be prevented, and deformation such as deflection of the upper division plate 121 and the lower division plate 122 themselves can be prevented or suppressed to the minimum. Therefore, the flatness of the upper partition plate 121 and the lower partition plate 122 can be further improved, and the dimensional accuracy can be improved.
As shown in fig. 14, the fitting connection portion between the vertical partition body upper portion 125a and the vertical partition body lower portion 125b has a shape that opens on the front surface side of the recess 226 provided in the vertical partition body upper portion 125 a. Therefore, the engagement and connection between the vertical partition body upper part 125a and the vertical partition body lower part 125b can be easily performed by simply pressing the engaging part 225 provided on the vertical partition body lower part 125b from the front to the rear. Further, the press-fitting of the engaging portion 225 into the concave portion 226 can be performed simultaneously with the mounting of the lower partition plate 122, so that the assembling property can be improved and the cost can be reduced.
On the other hand, the switching compartment 106 and the ice-making compartment 107, which are the left and right storage compartments formed by the upper partition plate 121 and the lower partition plate 122, are formed such that one switching compartment 106 has a larger volume than the other ice-making compartment 107, the other ice-making compartment 107 has a smaller volume than the switching compartment 106, and a (2 nd) thick portion 127a is formed in a side plate portion on the switching compartment 106 side where the volume is formed to be large and which has a wide opening. With this configuration, the rigidity of the switching chamber 106, which has a large opening and is easily weakened, can be increased, and the rigidity of the refrigerator main body 101 can be further increased.
The large door 110a of the left and right half-split doors of the refrigerating compartment 105 disposed above the switching compartment 106 and the ice making compartment 107, which are divided into the left and right compartments, is pivotally supported by the (2 nd) thick portion 127a of the switching compartment 106. Therefore, the strength of the portion to which the large cantilever moment load of the door 110a is directly applied can be increased, and even if the door 110a is formed of a heavy material such as a glass plate and is heavy, deformation of the refrigerator main body 101 and the like can be effectively suppressed.
In the present embodiment, the thickness of side plate 101a of the storage compartment in which refrigerator main body 101 is disposed at the lower part is set to be thicker than that of refrigerating compartment 105 (T2, T3, T4, T5 > T1). With such a configuration, the rigidity of the lower portion of the refrigerator main body 101, which receives a high proportion of the load of the refrigerator main body 101 and the door 110, is improved. Thus, even if the refrigerator main body 101 is increased in size, the door is formed of a glass plate or the like, or the refrigerator is increased in weight, the deformation of the refrigerator main body 101 can be minimized.
In particular, corner X, which is a connection portion between side plate 101a and bottom plate 101b of vegetable compartment 109 at the lowermost part of refrigerator main body 101, has (1 st) thick portion 126 having a greater thickness than the other portions except corner X at both corner X of side plate 101a and corner X of bottom plate 101 b. With this configuration, the rigidity of the corner portion X is greatly improved, and even if the load of the refrigerator main body 101 and the door 110 is continuously supported for a long period of time, the refrigerator main body 101 can be effectively prevented from being deformed.
The (1 st) thick portion 126 for improving the rigidity of the refrigerator main body 101 is formed only at the corner X which is the connection portion between the side plate portion 101a and the bottom plate portion 101b at the lower portion of the refrigerator main body 101. Therefore, deformation of the refrigerator main body 101 can be prevented without significantly reducing the capacity of the storage chamber (vegetable chamber 109 in the present embodiment) at the lowermost portion of the refrigerator main body 101.
In the present embodiment, not only the side plate portion 101a having the above-described thickness is provided in the refrigerator main body 101, but also the (1 st) thick portion 126b is provided on the bottom plate portion 101b side. With this configuration, the (1 st) thick portion 126b functions as a strength member against a moment load in the torsional direction applied to the corner X that is the connection portion between the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 when the door 110 is opened and closed. Therefore, as compared with the case where the (1 st) thick portion 126a is provided only on the side plate portion 101a, the resistance against the full load of the refrigerator main body 101 and the door 110 is improved, and the main body of the refrigerator main body 101 can be prevented from being deformed for a longer period of time.
As described above, the refrigerator according to the embodiment of the present invention is explained by using the example, but the present invention is not limited to this.
For example, in the present embodiment, the vertical partition body 125 is divided into the vertical partition body upper portion 125a and the vertical partition body lower portion 125 b. However, either the upper or lower vertical partition body upper part 125a or the vertical partition body lower part 125b may be formed integrally with either the upper partition plate 121 or the lower partition plate 122 as the vertical partition body 125, or may be engaged or joined with the upper partition plate 121 or the lower partition plate 122 as another member.
The storage compartment provided by dividing the space between upper partition plate 121 and lower partition plate 122 into two compartments by vertical partition 125 is not limited to ice making compartment 107 and switching compartment 106. For example, a storage chamber having other functions such as a quick freezing chamber and a freezing chamber may be used, or the storage chamber may be divided into two or more chambers.
As described above, the refrigerator 100 according to embodiment 2 of the present disclosure includes the refrigerator main body 101, the partitions 121, 122, and 123 that partition the interior of the refrigerator main body 101 into the storage compartments 105, 106, 107, 108, and 109, and the door 110 that opens and closes the storage compartments. At least one of the storage chambers 105, 106, 107, 108, 109 is divided into right and left by a vertical partition 125, and upper and lower partition plates 121, 122 of the storage chambers 106, 107 divided into right and left are connected by the vertical partition 125.
With this configuration, the upper and lower partition plates 121 and 122 constituting the left and right partitioned storage chambers 106 and 107 are reinforced against the torsional force by the connection of the vertical partition bodies 125. At the same time, even if the lateral width of storage compartments 106 and 107 is large, the lateral width in the lateral direction is divided into two by vertical partition 125, and vertical partition 125 is connected to partitions 121 and 122, so that the functions of partitions 121 and 122 as strength members are improved. Thus, even if the storage chambers 106 and 107 have a large width, the rigidity of the storage chambers 106 and 107 can be greatly increased, and the rigidity of the refrigerator main body 101 can be greatly increased. Therefore, even when a twisting force or the like is applied to the refrigerator main body 101 when the door 110 is opened or closed, it can be resisted. At the same time, the door 110 made of a heavy material such as a glass plate can resist a large weight, and deformation of the refrigerator main body 101 can be suppressed strongly. Even if the refrigerator main body 101 is increased in size in the lateral width direction and the lateral width dimensions of the upper and lower partitions 121 and 122 are increased, the upper and lower partitions 121 and 122 are connected by the vertical partition body 125 in the lateral width direction, and therefore, the upper and lower partitions 121 and 122 can be prevented from being deformed into a bulging shape. Therefore, a high-quality refrigerator with high dimensional accuracy and improved flatness of partition plates 121 and 122 can be obtained.
In the refrigerator 100 of the present embodiment, the vertical partition body 125 may be integrally formed with at least one of the upper partition plate 121 and the lower partition plate 122, and the upper partition plate 121 and the lower partition plate 122 of the vertical partition body 125 may be coupled by fitting the engaging portion 225 and the engaged portion 226 provided in the vertical partition body 125.
According to such a configuration, since the upper partition plate 121 and the lower partition plate 122 can be coupled by merely fitting the engaging portion 225 and the engaged portion 226, the coupling operation can be performed easily and quickly as compared with the case of coupling by screwing or the like. Further, since the longitudinal partition body 125 is formed integrally with at least one of the upper and lower partition plates 121 and 122, the number of parts can be reduced, and the working time can be shortened, and the present invention can be provided at low cost.
In the refrigerator 100 of the present embodiment, the vertical partition 125 may be constituted by a vertical partition upper portion 125a integrally formed with the upper partition plate 121 so as to protrude downward from the upper partition plate 121, and a vertical partition lower portion 125b integrally formed with the lower partition plate 122 so as to protrude upward from the lower partition plate 122. Further, a click portion 225 is provided on one of abutting joint end surfaces of the vertical partition body upper portion 125a and the vertical partition body lower portion 125b, and a recess 226 into which the click portion 225 is fitted is formed on the other.
With this configuration, the upper and lower partition plates 121 and 122 can be coupled to each other by merely fitting the engaging portion 225 provided on one of the vertical partition body upper portion 125a and the vertical partition body lower portion 125b into the recess 226 provided on the other. Therefore, the fastening operation can be performed easily and quickly as compared with the fastening operation by screwing or the like. Further, the vertical partition body upper portion 125a and the vertical partition body lower portion 125b are formed integrally with the upper and lower partition plates 121 and 122, respectively, so that the number of parts can be reduced, and the working time can be shortened, thereby providing them at low cost.
In the refrigerator 100 of the present embodiment, the storage compartments 106 and 107 partitioned by the upper partition plate 121 and the lower partition plate 122 in the left-right direction are formed such that one of the volumes is larger and the other volume is smaller, and the side plate portion 101a on the side of the storage compartment 106 having a larger volume and a larger opening has a thicker portion 127a having a larger wall thickness (No. 2) than the side plate portion 101a of the storage compartment 107 having a smaller volume.
With this configuration, the rigidity of the large storage chamber 106, which has a large opening and is likely to be weakened in strength, of the storage chambers 106 and 107 divided into the left and right chambers, can be increased by the (2 nd) thick portion 127a having a large thickness, and the rigidity of the refrigerator main body 101 can be further increased.
In the refrigerator 100 of the present embodiment, the storage compartment 105 disposed above the storage compartments 106 and 107 partitioned into the left and right sides has the left and right split doors 110. In this case, the left-right split doors 110 may be formed such that one door 110a has a larger left-right lateral width than the other door 110b, and the other door 110b has a smaller left-right lateral width than the one door 110 a. In this case, it is preferable that the storage chamber 106 having a larger opening out of the storage chambers defined in the left and right sides is disposed on the side of the pivotally-supported large door 110a, and the side plate portion 101a of the storage chamber 106 having the larger opening has a (2 nd) thick portion 127a having a thickness larger than that of the side plate portion 101a of the storage chamber 107 having the smaller opening.
With such a configuration, even if the storage chamber 106 having a large volume has a large opening and is easily weakened in strength, the rigidity can be improved, and the strength of the side plate portion 101a of the portion of the large door 110a to which the cantilever moment load is directly applied can be improved. Therefore, even if the door 110 is formed of a heavy material such as a glass plate and is heavy, deformation of the refrigerator main body 101 and the like can be effectively suppressed.

In this way, refrigerating room 105, switching room 106, and ice making room 107, freezing room 108, and vegetable room 109 are formed in refrigerator main body 101.
In the present embodiment, of partition plates 121, 122, 123, partition plate 121 that partitions refrigerating room 105 from switching room 106 and ice making room 107 provided side by side is configured by combining upper plate 121a and lower plate 121b as shown in fig. 12. Duct members 231 and 232 for forming a cold air passage communicating with cooling compartment 116 are disposed between upper plate 121a and lower plate 121b of partition plate 121. Further, a damper member 233 is disposed between the upper plate 121a and the lower plate 121b of the partition plate 121, and is filled with a foam heat insulating material (not shown) such as foam urethane.
Further, the upper partition plate 121 may have a front panel 330 on its front surface as shown in fig. 12. The front panel 330 is formed by integrally overlapping an upper front panel 330a of the upper panel 121a and a lower front panel 330b of the lower panel 121 b.
As shown in fig. 12, duct members 231 and 232 for forming the cold air passage are provided in the upper and lower portions of the upper partition plate 121 behind the lower plate 121 b. The damper part 233 is combined with the duct part 231 to control the direction of the cold air.
A sweating-preventing heat source mounting plate 228 is provided on the front surface of the partition plate 121, and reinforcing fittings 230 are provided at both right and left end portions of the sweating-preventing heat source mounting plate 228. Further, an upper partition plate reinforcing and decorating cover 229 is attached to the front surface of the partition plate 121 via a sweat-proof heat source mounting plate 228 and a reinforcing metal fitting 230. Hinge members 115 are fixed to both left and right end portions of the front surface of upper partition plate reinforcing/decorative cover 229 with screws or the like, and door 110(110a, 110b) of the refrigerating compartment disposed above partition plate 121 is pivotally supported by hinge members 115.
Hereinafter, the structure of the hinge member attachment portion to which the hinge member 115 is attached will be described with reference to fig. 16 to 25.

Fig. 20A to 20D are partially enlarged views of a door hinge member attachment portion of a refrigerator according to embodiment 3 of the present invention. Fig. 21 is a front view of a refrigerator door hinge member attachment portion according to embodiment 3 of the present invention. In addition, fig. 22 is a sectional view taken along line 22-22 of fig. 21, fig. 23 is a sectional view taken along line 23-23 of fig. 21, fig. 24 is a sectional view taken along line 24-24 of fig. 21, and fig. 25 is a perspective view of portion D of fig. 24.
In fig. 12, 16 to 24, and 25, the partition plate 121 is configured by combining the upper plate 121a and the lower plate 121b as described above. As shown in fig. 16, 23, and 24, the front panel 330 of the partition plate 121 is configured by overlapping an upper panel front panel 330a and a lower panel front panel 330b formed on each of the upper panel 121a and the lower panel 121b and integrating them with a front panel integration screw 331.
As shown in fig. 24 and 25, on the inner surface of the upper plate front panel 330a of the upper plate 121a of the partition plate 121 or the lower plate front panel 330b of the lower plate 121b of the partition plate 121, a reinforcing member 332 having a substantially L-shape is fastened to at least one of the upper plate front panel 330a and the lower plate front panel 330 b. Thus, the reinforcing member 332 can be provided so as to protrude from the foamed heat insulating material between the upper plate 121a and the lower plate 121 b. The reinforcing member 332 does not necessarily have to be substantially L-shaped, and may have any shape as long as it is not plate-shaped and is provided so as to protrude into the foamed heat insulating material.
As shown in fig. 17, a boss 333 for attaching a reinforcing component and a boss 334 for attaching a hinge member are formed integrally with the front panel 330 of the partition plate 121 (the upper panel front panel 330a of the upper plate 121 a).
As shown in fig. 16 and 24, heat insulating materials 335 such as foamed styrene are attached to the front surface portions of the upper plate 121a and the lower plate 121 b.
On the other hand, as shown in fig. 18A, the reinforcement fitting 230 has bent pieces 329a at upper and lower portions thereof. The front surface of the reinforcement metal fitting 230 is provided with a metal fitting mounting hole 336 and a hinge member mounting hole 337 corresponding to the reinforcement metal fitting mounting boss 333 and the hinge member mounting boss 334 formed in the front panel 330 of the partition plate 121.
In reinforcement fitting 230, fitting attachment hole 336 and hinge member attachment hole 337 are provided on the front surface of partition plate 121 so as to engage with reinforcement fitting attachment boss 333 and hinge member attachment boss 334 of partition plate 121. The reinforcing metal fitting 230 provided on the front surface of the partition plate 121 is fixed to the front surface of the partition plate 121 by screwing a fitting attachment screw 339 inserted into a fitting attachment hole 336 into the reinforcing metal fitting attachment boss 333, as shown in fig. 19, 22, and 23.
At this time, the reinforcing metal fitting 230 is positioned by fitting the bent piece 329a into the protrusion 338 (see fig. 18B) provided in the upper plate 121a, and the fitting attachment hole 336 and the hinge member attachment hole 337 are aligned with the reinforcing metal fitting attachment boss 333 and the hinge member attachment boss 334 of the partition plate 121.
As shown in fig. 19, 21, and 22, the reinforcing metal fitting 230, particularly the reinforcing metal fitting 230 on the side of the pivotally supporting large door 110a in the present embodiment, has an extension piece 329b whose end extends to the side plate portion front end surface 101aa of the side plate portion 101a of the refrigerator main body 101. The reinforcing metal fitting 230 is fastened to the side plate portion end surface 101aa together with the end portion of the top partition plate reinforcing/decorating cover 229 in a state where the extension piece portion 329b is inserted into the inside of the side plate portion end surface 101aa of the refrigerator main body 101 together with the end portion of the top partition plate reinforcing/decorating cover 229.
In this state, hinge member 115 is disposed on the front surface of top partition plate reinforcing/decorative cover 229 disposed on the front surface of partition plate 121 so as to cover reinforcing metal fitting 230, and hinge member mounting screw 340 is screwed to hinge member mounting boss 334 of partition plate 121 through hinge member mounting hole 337 of reinforcing metal fitting 230. Thus, hinge member 115, top partition plate reinforcing/decorative cover 229, and reinforcing fitting 230 are fastened to the front surface of partition plate 121.
In the present embodiment, the hinge member 115 is also fastened to the side plate portion front end surface 101aa of the refrigerator main body 101 by the hinge attachment auxiliary screw 341 together with the extension piece portion 329b of the reinforcement metal fitting 230 and the end portion of the top partitioning plate reinforcing/decorating cover 229.
As shown in fig. 20A to 20D, the hinge member 115 is attached and fixed to the refrigerator main body 101. That is, first, the reinforcing metal fitting 230 is fixed to the front surface of the partition plate 121 via the sweat-proof heat source mounting plate 228 (fig. 20A). Next, defrosting refrigerant pipe 342 is disposed behind the front surface of partition plate 121 (fig. 20B), partition plate reinforcing and decorative cover 229 is disposed (fig. 20C), and hinge member 115 is screwed from the front surface (fig. 20D).
The refrigerator 100 configured as above will be described with respect to its operational effects.
Hinge member 115 fixed to refrigerator main body 101 is attached to support door 110a and allow refrigerating room 105 to be opened and closed. The load of the door 110a is applied to the reinforcement fitting 230 to which the hinge member 115 is attached and fixed via the hinge member 115.
The reinforcing metal fitting 230 has an extension piece 329b extending to the side plate portion front end face 101aa of the refrigerator main body 101 at an end portion thereof, and the extension piece 329b of the reinforcing metal fitting 230 is fixed to the side plate portion front end face 101aa of the refrigerator main body 101 together with an end portion of the top separation plate reinforcing/decorative cover 229. With this configuration, the door load applied to the reinforcement fitting 230 can be supported by the side plate 101a of the refrigerator main body 101 together with the partition plate 121, and the strength of the hinge attachment portion can be greatly increased.
In detail, in the related art, the reinforcement fitting is fixed only to the partition plate 121, and the door load applied to the reinforcement fitting 230 is supported only by the partition plate 121. However, in the present embodiment, since the extension piece portion 329b of the reinforcement metal fitting 230 is fixed to the side plate portion front end surface 101aa of the refrigerator main body 101, the door load can be supported by the side plate portion front end surface 101aa of the refrigerator main body 101. Further, although the end of the top partition plate reinforcing/finishing cover 229 that covers the front surface of the partition plate 121 is also fixed to the side plate portion front end surface 101aa of the refrigerator main body 101 in the related art, the door load is not sufficiently supported only by this, but the present invention can compensate for the insufficient support of the door load by fixing the reinforcing metal fitting 230 to the side plate portion front end surface 101aa, and can improve the strength of the hinge attachment portion as compared with the related art.
That is, the strength of the hinge member attachment portion is greatly increased by adding a reinforcing effect by fixing the extension piece portion 329b of the reinforcing metal fitting 230 to the refrigerator main body side plate portion 101 a.
Therefore, even if the door 110a is enlarged in size and has a large weight due to the formation of a glass door (the door is formed of a heavy material such as a glass plate), deformation of the hinge attachment portion, door sagging, and the like can be effectively suppressed.
In particular, the reinforcing metal fitting 230 is set to be thicker than the top separator plate reinforcing/decorative cover 229, and as illustrated in the present embodiment, the bending pieces 329a are provided at the upper and lower portions thereof, whereby the rigidity can be improved as compared with the top separator plate reinforcing/decorative cover 229. Since a large reinforcing effect can be obtained by fixing the reinforcing metal fitting 230 to the side plate portion front end surface 101aa, door sagging and the like can be effectively prevented.
Further, a part of the hinge member 115 is fastened to the side plate portion front end surface 101aa of the refrigerator main body 101 together with the extension piece portion 329b of the reinforcement metal fitting 230 and the end portion of the top partition plate reinforcing/decorating cover 229. According to such a configuration, hinge member 115 is also directly supported by side plate 101a of the refrigerator main body, and door sagging and the like can be effectively prevented by the support of both side plate 101a of the refrigerator main body and partition plate 121.
The partition plate 121 is configured by combining an upper plate 121a and a lower plate 121b, and an upper plate front panel 330a of the upper plate 121a constituting the front surface of the partition plate 121 and a lower plate front panel 330b of the lower plate 121b constituting the front surface of the partition plate 121 are overlapped and fastened and fixed by screws. With this structure, the strength of the front panel 330 itself to which the hinge member 115, the top partition plate reinforcing and decorating cover 229, and the partition plate 121 of the reinforcing metal fitting 230 are fixed can be increased. Therefore, even in the structure in which the upper panel front panel 330a of the upper panel 121a and the lower panel front panel 330b of the lower panel 121b are overlapped, the strength of the hinge attachment portion can be improved, and door sagging and the like can be effectively prevented.
Further, since the partition plate 121 is configured by filling a foamed heat insulating material therein, the strength of the partition plate 121 itself is improved by the foamed heat insulating material, and the strength of the hinge attachment portion can be further improved.
The partition plate 121 has a structure in which a reinforcing member 332 is disposed on the inner surface of the front plate 330, and the reinforcing member 332 protrudes into the foamed heat insulating material. According to such a configuration, the strength of the front panel 330 of the partition plate 121 is greatly improved by the reinforcing member 332 provided to protrude into the foamed heat insulating material. Therefore, the strength of the hinge attachment portion is greatly improved, and door sagging and the like can be more effectively prevented.
As described above, the refrigerator 100 of the present embodiment is explained using the embodiment, but the present invention is not limited to this.
For example, in the present embodiment, the side portion of the pivot support pin 115a of the hinge member 115 is also fastened to the side plate portion front end surface 101aa of the refrigerator main body 101 together with the extension piece portion 329b of the reinforcement metal fitting 230 and the end portion of the top partition plate reinforcing/decorating cover 229. However, the side portion of the pivot support pin 115a may be in a free state without being fixed to the side plate portion front end surface 101aa of the refrigerator main body 101.
In the present embodiment, as a measure for improving the strength of the hinge attachment portion, an example in which the upper panel front 330a of the upper panel 121a and the lower panel front 330b of the lower panel 121b are fixed to each other in a superposed manner, or a reinforcing member 332 is disposed on the inner surface of the front 330 of the partition panel 121 so as to protrude into the foamed heat insulating material is shown, but these may be performed as needed.
As described above, refrigerator 100 according to embodiment 3 of the present invention includes: a refrigerator main body 101; a partition plate 121 partitioning the inside of the refrigerator main body 101; a top separation plate reinforcing and decorating cover 229 covering the front surface of the separation plate 121; a hinge member 115 disposed on the front surface of the top separation plate reinforcing/finishing cover 229; and a reinforcement metal fitting 230 disposed on the rear surface of the top partition plate reinforcement/decorative cover 229 facing the hinge member 115. Hinge element 115 is fixed to the front surface of partition 121 together with partition 121 and reinforcing fitting 230. The reinforcing metal fitting 230 has an extension piece 329b extending from an end thereof to the side plate portion front end surface 101aa of the refrigerator main body 101, and the extension piece 329b of the reinforcing metal fitting 230 is fixed to the side plate portion front end surface 101aa of the refrigerator main body 101 together with the end of the top separation plate reinforcing/decorative cover 229.
According to such a configuration, the reinforcing metal fitting 230 that supports the door load is also integrated with the side plate portion 101a of the refrigerator main body 101 together with the partition plate 121, and supports the door load applied to the reinforcing metal fitting 230. In other words, the door load applied to the reinforcing metal fitting 230 can be supported by the side plate portion 101a of the refrigerator main body 101 together with the partition plate 121, and the strength of the hinge attachment portion can be greatly increased. That is, the strength of the hinge attachment portion is greatly increased by the reinforcing effect of the extension piece 329b of the reinforcing metal fitting 230 fixed to the side plate portion 101a of the refrigerator main body 101. Therefore, even if the door 110 is increased in size and increased in weight due to the formation of a glass door, deformation of the hinge attachment portion, door sagging, and the like can be effectively suppressed.
In the refrigerator 100 according to embodiment 3 of the present invention, a part of the hinge member 115 may be fastened to the side plate portion front end surface 101aa of the refrigerator main body 101 together with the extension piece portion 329b of the reinforcement metal fitting 230 and the end portion of the top-partitioning-plate reinforcing/decorating cover 229.
With this configuration, hinge member 115 is also directly supported by side plate 101a of refrigerator main body 101, and door sagging and the like can be effectively prevented by supporting both side plate 101a of refrigerator main body 101 and partition plate 121.
In refrigerator 100 according to embodiment 3 of the present invention, partition plate 121 is configured by combining upper plate 121a and lower plate 121b, and upper plate front plate 330a and lower plate front plate 330b constituting the front surface of partition plate 121 are fixed to each other in a superposed manner.
With this structure, the strength of the front surface itself of the partition plate 121 to which the hinge member 115, the top partition plate reinforcing/decorative cover 229, and the reinforcing metal fitting 230 are fixed can be increased. Therefore, the strength of the hinge attachment portion can be further improved, and door sagging and the like can be more effectively prevented.
In refrigerator 100 according to embodiment 3 of the present invention, partition plate 121 has a structure in which a foamed heat insulating material is filled therein.
With this configuration, the strength of the partition plate 121 itself is increased by the foamed heat insulating material, and the strength of the hinge attachment portion can be further increased.
In refrigerator 100 according to embodiment 3 of the present invention, partition plate 121 has a structure in which reinforcing member 332 is disposed on the inner surface of upper plate front panel 330a and projects into the foamed heat insulating material.
With this configuration, the strength of the portion of the upper front panel 330a of the partition plate 121 is greatly improved by the reinforcing member 332 protruding into the foamed heat insulating material. Therefore, the strength of the hinge attachment portion is greatly improved, and door sagging and the like can be more effectively prevented.

In the present embodiment, one door 110a of the left and right split doors 110 has a larger width in the left-right direction than the other door 110 b.
On the other hand, as shown in fig. 26, a cooling chamber 116 is formed on the rear surface of the refrigerator main body 101. Cooling compartment 116 is provided with a cooler 117 for generating cold air, and an air blowing fan 118 for supplying cold air to each of refrigerating compartment 105, freezing compartment 108, vegetable compartment 109, and the like. A compressor 119 is provided in a deep portion of the top surface of the refrigerator main body 101. A hydrocarbon refrigerant, for example, isobutane refrigerant, is sealed in a refrigeration cycle in which a condenser (not shown), a heat radiation pipe (not shown) for radiating heat, a capillary tube (not shown), and a cooler 117 are connected in this order in an annular shape. The refrigeration cycle is cooled by the compressor 119.
A radiation heater 421 for defrosting frost and ice adhering to the cooler 117 during cooling is provided in the lower space, and a drain pipe 422 penetrating the outside of the storage is provided below the radiation heater 421.
Here, as described above, the refrigerator main body 101 includes: refrigerating room 105, switching room 106, and a plurality of storage rooms such as ice making room 107, freezing room 108, and vegetable room 109 provided in parallel therewith. Each storage compartment is formed by partitioning the inside of the refrigerator main body 101 by partitions 121, 122, and 123.
As shown in fig. 27, 28, and 30, of partition plates 121, 122, and 123, partition plate 121 that partitions refrigerating compartment 105 from switching compartment 106 and ice making compartment 107 provided side by side is configured by combining upper plate 121a and lower plate 121b via duct members 231 and 232 for forming a cold air passage and door member 233. The hollow portion between the front panel 330 composed of the upper panel front panel 330a of the upper panel 121a and the lower panel front panel 330b of the lower panel 121b, the side panel 430, and the duct member 231 is filled with a foam heat insulating material 104 such as foamed polyurethane.
A sweating-preventing heat source mounting plate 228 is provided on the front surface of the partition plate 121, and reinforcing fittings 230 are provided at both right and left end portions of the sweating-preventing heat source mounting plate 228. A partition front plate 229 serving as a top partition plate reinforcing and decorating cover is attached to the front surface of the partition plate 121 via a sweat-proof heat source attachment plate 228 and a reinforcing metal fitting 230. The hinge members 115 are fixed to both right and left end portions of the partition front plate 229 with screws or the like. Hinge member 115 pivotally supports doors 110(110a, 110b) of the refrigerating compartment formed above partition plate 121.
As shown in fig. 31, 32A, and 32B, partition plate 121 has ribs 434 integrally formed on the inner surface of upper plate 121a, which serves as the bottom surface of refrigerating compartment 105. As shown in fig. 29, the rib 434 is embedded in the foamed heat insulating material 104 filled in the hollow portion of the partition plate 121 and has a hook-like shape mechanically coupled thereto. In the present embodiment, the rib 434 is formed in a bridge shape having hook portions W at both ends.
As shown in fig. 31, 32A, and 32B, the rib 434 includes a rib 434a provided on the front portion of the partition plate 121 and a rib 434B provided on the rear portion. A plurality of ribs 434a and 434b are also arranged in the left-right direction. In the present embodiment, the front-rear length L of the rib 434a provided at the front portion is longer than the front-rear length L of the rib 434b provided at the rear portion.
A plurality of ribs 434a and 434b are disposed in a direction intersecting with an opening surface of the urethane filling port 435 provided at a front portion of the side plate 430 of the upper plate 121a (see fig. 31).
The refrigerator 100 of the present embodiment configured as described above will be described with respect to its operational effects.
First, filling of polyurethane in the partition plate 121 will be described. In the refrigerator 100 of the present embodiment, as shown in fig. 30, the upper plate 121a and the lower plate 121b of the partition plate 121 are combined to form a hollow partition plate 121 in advance, and the partition plate 121 is incorporated into the refrigerator main body 101. In this state, the foamed heat insulating material 104 is filled between the inner box 103 and the outer box 102 of the refrigerator main body 101.
Accordingly, foam heat insulating material 104 flows into the hollow portion of partition plate 121 from a urethane discharge port (not shown) between inner box 103 and outer box 102 of refrigerator main body 101 through urethane filling port 435 and solidifies, and partition plate 121 and refrigerator main body 101 are formed integrally.
In the refrigerator 100 configured as described above, when the bridge-shaped rib 434 is formed on the inner surface of the upper plate 121a of the partition plate 121, the bridge-shaped rib 434 is embedded in the foamed heat insulating material 104 of the partition plate 121. According to such a structure, the ribs 434 are mechanically bonded to the foamed heat insulating material 104. That is, the foaming and insulating material 104 flows between the bridge-shaped portion of the rib 434 and the upper plate 121a and is cured, and the foaming and insulating material 104 is mechanically coupled to the hook-shaped portions W at both ends of the bridge shape of the rib 434. With such a configuration, the peeling of the upper plate 121a of the partition plate 121 from the foamed heat insulating material 104 can be more reliably suppressed.
In particular, in the case where the rib 434 has a bridge shape, the rib 434 is coupled to the upper plate 121a of the partition plate 121 at the hook portions W of two locations at both ends of the bridge shape. Therefore, the mechanical bonding between the foamed heat insulating material 104 and the ribs 434 becomes stronger, so the peeling prevention effect can be improved. As the shape having the hook-shaped portion W that can be mechanically coupled to the foamed heat insulating material 104, a substantially L-shaped shape is conceivable, but in the case of the substantially L-shaped shape, the hook-shaped portion W mechanically coupled to the foamed heat insulating material 104 is in the shape of a cantilever beam at one location, and therefore is slightly inferior in strength. However, since the rib 434 is configured to have a bridge shape as in the present embodiment, the hook-shaped portions W mechanically coupled to the foamed heat insulating material 104 are formed at two locations at both ends of the bridge shape, and therefore, are formed in a double support beam shape, and the mechanical coupling force is increased.
In the present embodiment, the ribs 434 have a bridge shape, and a plurality of the ribs are arranged so as to intersect with the opening surfaces of the urethane filling ports 435 provided on the left and right sides of the front of the partition plate 121. According to such a configuration, the foamed heat insulating material 104 flowing from the urethane filling port 435 into the hollow portion of the partition plate 121 reliably flows into the gap between the inner surface of the upper plate 121a of the partition plate 121 and the bridge portion of the rib 434, and is filled and cured. Therefore, the mechanical bonding between the foamed heat insulating material 104 and the bridge-shaped ribs 434 becomes more reliable, and the separation of the upper plate 121a of the partition plate 121 and the foamed heat insulating material 104 can be more reliably suppressed.
Further, since the foaming heat insulator 104 can be filled into the partition plate 121 at the same time by filling the foaming heat insulator 104 into the refrigerator main body 101, the separation of the upper plate 121a of the partition plate 121 and the foaming heat insulator 104 can be prevented while improving productivity.
Further, a plurality of bridge-shaped ribs 434 are arranged in the left-right direction at the front and rear portions of the partition plate 121. Meanwhile, the front rib 434a is formed to have a longer front-rear length L than the front-rear length L of the rear rib 434 b. With this configuration, the upper plate 121a at the front portion of the partition plate 121 can be mechanically coupled to the bridge-shaped rib 434 more strongly over the entire partition plate area.
Therefore, peeling of the front portion of the partition plate 121, which easily falls into the eyes of the user when the door 110 is opened, can be effectively prevented. In particular, in the present embodiment, the partition plate 121 has a rear portion covered with the micro freezing chamber 105a, and only a front portion is likely to fall into the eyes of the user when the door is opened, so that the design can be more effectively improved.
Further, rib 434aa located near the door pivot supporting portion of partition plate 121 is provided at a portion closer to the front end surface of partition plate 121 than other rib 434ab at the central portion. With this configuration, the upper plate 121a and the rib 434 that pivotally support the left and right portions of the partition plate 121 of the door 110 are mechanically coupled to each other on the front end surface side.
Therefore, the separation of the upper plate 121a and the foaming and heat insulating material 104 near the shaft support portions at both ends of the partition plate 121, which is easily deformed into the hanging-down state by the door load, can be effectively suppressed.
Further, a rib 434ab located at a central portion other than the rib 434aa located near the door pivot supporting portion of the partition plate 121 is located at a substantially central portion in the front-rear direction of the partition plate 121. With this configuration, since the mechanical bonding between the upper plate 121a at the substantially central portion of the partition plate 121 and the foamed heat insulating material 104 can be ensured, a good mechanical bonding can be ensured over the entire partition plate 121.
In the present embodiment, as shown in fig. 33, reinforcing metal fittings 230 are provided on the front end surfaces of the left and right shaft support portions that serve as the partition plate 121. The end 230b of the reinforcing metal fitting 230 extends to the side plate portion front end surface 101aa of the refrigerator main body 101, and is fixed to the side plate portion front end surface 101aa with screws or the like. According to such a configuration, the reinforcement metal fitting 230 can reliably prevent the front sagging deformation of the shaft support portion of the partition plate 121, and can more effectively suppress the separation of the upper plate 121a and the foamed heat insulating material 104 in the vicinity of the shaft support portion of the partition plate 121.
That is, since end 230b of reinforcing metal fitting 230 extends to and is fixed to side plate portion front end surface 101aa of refrigerator main body 101, the load applied to door 110 of the door pivot supporting portion of partition plate 121 is also supported by side plate portion front end surface 101aa of refrigerator main body 101 to which reinforcing metal fitting 230 is fixed. Therefore, the front sagging deformation of the front end surface of the partition plate 121 can be prevented strongly.
This makes it possible to more effectively prevent the separation between the upper plate 121a and the foamed heat insulating material 104 in the vicinity of the pivotally supporting portion of the partition plate 121, in conjunction with the effect of providing the rib 434aa located in the vicinity of the pivotally supporting portion of the door closer to the distal end surface portion of the partition plate 121 than the other rib 434ab located in the central portion.
As described above, the refrigerator 100 of the present embodiment is explained using the embodiment, but the present invention is not limited to this.
For example, in the present embodiment, the rib 434 provided on the inner surface of the upper plate of the partition plate 121 is formed in a bridge shape. However, the shape may be a shape having a hook-shaped portion W embedded in the foamed heat insulating material 104 and mechanically connectable thereto, for example, a substantially L-shape as described above.
In the present embodiment, rib 434 is provided on upper plate 121a of partition plate 121, which serves as the bottom surface of refrigerating compartment 105. However, the rib 434 may be provided on the lower plate 121b side of the top surfaces of the switching compartment 106 and the ice making compartment 107.
The partition provided with the ribs 434 is not limited to the partition 121, and may be another partition 122 or 123, that is, any partition that partitions the storage compartments.
As shown in fig. 30, 31, and the like, the ribs 434 are provided on the partition plate 121 so as to be separated in the front-rear direction, but the present invention is not limited to the illustrated portions, and may be provided only in other portions where separation prevention is required.
In the case where the ribs 434 are provided separately in the front-rear direction of the partition plate 121, the rib 434b provided on the rear portion of the partition plate 121 is shorter than the rib 434a provided on the front portion of the partition plate 121 in the present embodiment. The front and rear ribs 434(434a, 434b) may be set to the same length.
In the present embodiment, the rib 434aa near the pivot support portion among the ribs 434a provided on the front portion of the partition plate 121 is provided on the front end surface portion of the partition plate 121, but the separation of the partition plate 121 at the substantially central portion can also be prevented by providing another rib 434 on the front end surface portion of the partition plate 121 so that the front-rear length thereof extends rearward.
As described above, the refrigerator 100 of the present embodiment includes: the refrigerator main body 101, partitions 121, 122, 123 forming a plurality of storage compartments 105, 106, 107, 108, 109 in the refrigerator main body 101, and doors 110, 111, 112, 113, 114 opening and closing the storage compartments 105, 106, 107, 108, 109. The partition plate 121 is filled with the foaming and heat insulating material 104 at the hollow portion inside, and a rib 434 having a hook portion W is provided on the inner surface of the upper plate 121a of the partition plate 121. The rib 434 has a structure embedded in the foamed heat insulating material 104.
According to such a configuration, since the hook-shaped portion W of the rib 434 provided on the inner surface of the upper plate 121a of the partition plate 121 is mechanically bonded to the heat insulating foam material 104, the upper plate 121a of the partition plate 121 can be prevented from peeling off from the heat insulating foam material 104.
In refrigerator 100 of the present embodiment, foam heat insulating material 104 may be filled between inner box 103 and outer box 102 in refrigerator main body 101, and partition plate 121 may be provided with urethane filling ports 435 communicating between inner box 103 and outer box 102 of refrigerator main body 101 on the front left and right sides. In addition, the rib 434 may have a bridge shape and be configured to cross the opening face of the urethane filling port 435.
With this configuration, the foam heat insulating material 104 can be simultaneously filled into the partition plate 121 by filling the foam heat insulating material 104 into the refrigerator main body 101. The foamed heat insulating material 104 flowing into the partition plate 121 from the urethane filling port 435 reliably flows between the inner surface of the upper plate 121a of the partition plate 121 and the bridge-shaped ribs 434 and is cured. Further, since the hook-shaped portions W of the rib 434, which are mechanically coupled to the foamed heat insulating material 104, are located at both ends of the bridge shape, the mechanical coupling between the foamed heat insulating material 104 and the bridge-shaped rib 434 is secured and strong. Therefore, productivity can be improved by filling the refrigerator main body 101 and the foamed heat insulating material 104 of the partition plate 121 at the same time, and peeling of the upper plate 121a of the partition plate 121 and the foamed heat insulating material can be prevented more reliably and strongly.
In the refrigerator of the present embodiment, a plurality of ribs 434 having a bridge shape are provided in a row in the left-right direction of partition plate 121. In addition, the ribs 434 are separately provided at the front and rear of the partition plate 121. Further, the front-rear length L of the rib 434a provided in the front portion may be longer than the front-rear length L of the rib 434b provided in the rear portion.
According to such a configuration, the mechanical coupling of the upper plate 121a of the divider plate 121 and the rib 434a of the front portion of the divider plate 121 can be achieved strongly and widely, and thus the peeling of the front portion of the divider plate 121, which is likely to fall into the eyes of a user when the door 110 is opened, can be effectively prevented.
In refrigerator 100 of the present embodiment, door 110 may be pivotally supported at both left and right ends of partition plate 121, a plurality of ribs 434 may be provided on the inner surface of upper plate 121a of partition plate 121 in the left-right direction, and rib 434aa near the pivotal support portion of door 110 among ribs 434 may be provided on a portion closer to the front end surface of partition plate 121 than other rib 434 ab.
According to such a configuration, the mechanical coupling of the upper plate 121a of the right and left partitions 121 of the partition 121 pivotally supporting the door 110 and the rib 434 is performed on the front end surface side of the partition 121 close to the pivotally supporting portion of the door 110. This can more effectively suppress the peeling of the upper plate 121a and the foamed heat insulating material 104 from occurring in the vicinity of the pivot support portion of the door 110, which is likely to cause the peeling of the door 110 due to the load applied thereto.
Industrial applicability
As described above, the present invention can provide a refrigerator which can prevent deformation of a refrigerator main body without significantly reducing the capacity of the refrigerator, and which can save space and has high reliability of large capacity. Therefore, the present invention can be widely applied to not only general refrigerators but also commercial refrigerators, wine chests, other cooling apparatuses, and the like.
