Description
Technical Field
The invention relates to a refrigeration and freezing technology, in particular to a refrigeration and freezing device.
Background
Most of the existing refrigerators rely on the suction between the door sealing magnetic stripe and the metal case shell to realize the sealing between the door body and the case body. On the one hand, sealing reliability is relatively poor, and on the other hand, the heat conductivity of magnetic stripe, plastics and metal box shell is different, and has great difference in temperature inside and outside the refrigerator, so box shell department produces longer heat bridge easily, and cold volume loss is serious, and then leads to the energy consumption to increase, still can cause the chamber door to combine the department to frost.
In order to solve the problem of cold leakage, most of the existing solutions adopt a mechanical interlocking structure to replace a door seal. For example, bosch siemens corporation discloses a hinge type door closing structure, maca koma corporation discloses a handle structure for assisting in opening a door, and corson corporation discloses a structure which comprises a door hinge and utilizes the self weight of a door body to realize automatic door closing, and the like.

In order to achieve the above object, the present invention provides a refrigerating and freezing apparatus comprising:
the refrigerator comprises a refrigerator body, a cabinet body and a door, wherein a storage space is limited in the refrigerator body, the refrigerator body is provided with a cabinet shell for forming the outside of the refrigerator body and an inner container for forming the inside of the refrigerator body, and the front parts of two side plates of the cabinet shell are respectively provided with a cabinet shell connecting part for connecting with the inner container;
the door body is connected with the box body and used for opening and/or closing the storage space; and
the door seal is arranged on the rear surface of the door body so as to form airtight seal between the refrigerator body and the door body when the door body is in a closed state; wherein
The farthest end of the outer section of the case shell connecting part exposed outside the case body, which extends from outside to inside in the transverse direction, does not exceed the position of the starting end of the section, adjacent to the case shell connecting part, of the door seal, which extends from outside to inside in the transverse direction, so that the door seal is in close contact with the inner container of the case body when the door body is in a closed state.
Optionally, the outer section of the case connecting part exposed to the outside of the case body is a vertical plane with a cross section of a horizontal line segment, and the horizontal line segment extends along the transverse direction; and is
The length of the horizontal line section is smaller than the shortest distance between the section of the door seal adjacent to the case connecting part and the side plate adjacent to the case connecting part.
Optionally, an outer section of the case connecting part exposed outside the case body is a curved surface with an arc-shaped cross section, and the arc is protruded forwards; and is
The length of the projection of the arc in a vertical plane perpendicular to the front-back direction along the transverse direction is smaller than the shortest distance between the section of the door seal adjacent to the case shell connecting part and the side plate adjacent to the case shell connecting part.
Optionally, the case connection further has an inner section hidden inside the case, and a farthest end of the inner section extending from outside to inside in the transverse direction does not exceed a position of a starting end of the section of the door seal adjacent to the case connection extending from outside to inside in the transverse direction.
Optionally, the inner container has an inner container connecting portion on each of two lateral sides of the inner container to be respectively engaged with the two case connecting portions disposed on the front portions of the two side plates of the case, so that the inner container is fixedly connected to the case.
Optionally, the door seal is a demagnetized seal.

Optionally, the air bag portion has a main air bag for press-contacting with the box body, two inner auxiliary air bags symmetrically disposed in lateral front of the main air bag, and two outer auxiliary air bags symmetrically embracing laterally outward of the main air bag and the two inner auxiliary air bags.
Optionally, the two side plates of the cabinet and the two cabinet connecting parts are made of metal plates, and the inner container is made of plastic plates.
The refrigeration and freezing device breaks through the traditional design concept and the improvement direction, and the box shell connecting part of the box body is specially designed, so that the farthest end of the outer section exposed outside the box body, which extends from outside to inside in the transverse direction, does not exceed the position of the starting end of the section, adjacent to the box shell connecting part, of the door seal, which extends from outside to inside in the transverse direction. Therefore, when the door body is in a closed state, the door seal can be directly in close contact with the inner container of the box body. Compared with the prior art, the refrigerator shell connecting part has the advantages that the length of the inward extension of the outer section of the refrigerator shell connecting part is shortened, and the door body is not contacted with the door seal when in a closed state, so that the possibility of heat leakage at the refrigerator shell due to a heat bridge effect is reduced, the cold loss is effectively reduced, and the energy consumption of a refrigerating and freezing device is reduced.

That is, the inward extension length of the inner section of the cabinet connecting portion is also relatively short, thereby further reducing or even avoiding heat leakage at the cabinet due to the heat bridge effect, and further reducing the loss of cooling capacity.
Furthermore, because the door seal of the refrigerating and freezing device is a demagnetized seal strip, the phenomenon of obvious cold leakage at the door seal can be avoided, thereby further reducing the energy consumption of the refrigerating and freezing device and improving the heat preservation performance of the refrigerating and freezing device.
Furthermore, because the air bag part of the door seal is provided with a plurality of air bags which are symmetrically arranged, the air bag part can be uniformly deformed when the door seal is subjected to extrusion action (such as the action of suction force or locking force between the refrigerator body and the door body of the refrigerating and freezing device), so that the air bag part is allowed to be in uniform extrusion contact with the refrigerator body of the refrigerating and freezing device with a large area, the airtight sealing between the refrigerator body and the door body of the refrigerating and freezing device is facilitated, certain adhesive force can be formed between the air bag part and the refrigerator body, the requirement on the suction force between the refrigerator body and the door body is reduced, and the possibility of the door body bouncing is reduced.
The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

Detailed Description
A refrigerating and freezing apparatus according to an embodiment of the present invention is provided, fig. 1 is a schematic configuration diagram of a refrigerating and freezing apparatus according to an embodiment of the present invention, fig. 2 is a schematic sectional view of a refrigerating and freezing apparatus according to an embodiment of the present invention, fig. 3 is a schematic configuration enlarged view of a portion a in fig. 2, fig. 4 is a schematic sectional view of a refrigerating and freezing apparatus according to another embodiment of the present invention, and fig. 5 is a schematic configuration enlarged view of a portion B in fig. 4. Referring to fig. 1 to 5, the refrigerating and freezing apparatus of the present invention includes a cabinet 20, a door 30, and a door seal 10.
The cabinet 20 defines a storage space therein, and has a case 21 for forming an exterior thereof and an inner container 22 for forming an interior thereof. The front parts of the two side plates 211 of the case 21 are respectively provided with a case connecting part 23 for connecting with the inner container 22. Specifically, the case 20 has a forward opening at a front side thereof for a user to access items therethrough. The cabinet 21 may include a U-shaped shell having two opposing and parallel side panels 211 and a top panel connected between the tops of the two side panels 211 and a back panel. A foaming layer for heat preservation and insulation is formed between the box shell 21 and the inner container 22.
The door 30 is connected to the cabinet 20 to open and/or close a storage space of the cabinet 30. Specifically, in some embodiments, the door body 30 may be pivotably connected to the cabinet 20 by a pivot shaft extending in a vertical direction, and a side of the door body 30 adjacent to the pivot shaft thereof is a pivot side and a side away from the pivot shaft thereof is an opening side. The door 30 opens the storage space of the cabinet 20 at its opening side. In other embodiments, the door 30 may be connected to the cabinet 20 by a push-pull or other suitable means.
The door seal 10 is provided to a rear surface of the door body 30 to form an airtight seal between the cabinet 20 and the door body 20 when the door body 30 is in a closed state. Specifically, the door seal 10 may be disposed on a rearward surface of the door body 30 adjacent to a peripheral edge thereof. In some embodiments, the door seal 10 may be annular in shape, including two vertical sections extending in a vertical direction and top and bottom transverse sections extending in a transverse direction. In other embodiments, the door seal 10 may be enclosed by four strip-shaped sections.
The farthest end of the outer section 231 of the case connecting portion 23 exposed to the outside of the cabinet 20 extending laterally from the outside to the inside does not exceed the position of the start end of the section of the door seal 10 adjacent to the case connecting portion 23 extending laterally from the outside to the inside, so that the door seal 10 is in close contact with the inner container 22 of the cabinet 20 when the door 30 is in the closed state. The direction "from outside to inside in the lateral direction" herein means a direction from the side of the side plate 211 where the case connecting portion 23 is located toward the vertical bisector of the forward opening of the cabinet 20. For example, in fig. 3 and 5, the farthest end of the outer section 231 of the case connecting portion 23 located on the left side extending to the right in the lateral direction does not exceed the position of the start end of the left section of the door seal 10 extending to the right in the lateral direction. That is, the farthest end of the outer section 231 of the case connecting portion 23 on the left side extending rightward in the lateral direction is located on the left side of the starting end of the left section of the door seal 10 extending rightward in the lateral direction. Likewise, the farthest end of the outer section 231 of the case connecting portion 23 located on the right side extending leftward in the lateral direction does not exceed the position of the start end of the right section of the door seal 10 extending leftward in the lateral direction. That is, the farthest end of the outer section 231 of the case connecting portion 23 on the right side extending leftward in the lateral direction is located on the right side of the starting end of the right section of the door seal 10 extending leftward in the lateral direction.
The invention can make the door seal 10 directly contact with the inner container 22 of the box 20 when the door is in a closed state by specially designing the box shell connecting part 23. That is, compared with the prior art, the invention shortens the length of the inward extension of the outer section 231 of the case connecting part 23, so that the outer section does not contact with the door seal 10 when the door body 30 is in the closed state, thereby reducing the possibility of heat leakage at the case 21 due to the heat bridge effect, further effectively reducing the loss of cooling capacity and reducing the energy consumption of the refrigerating and freezing device 1.
Further, the two side plates 211 and the two case connecting portions 23 of the case 21 are made of a metal material, and the inner container 22 is made of a plastic material.
In some embodiments of the invention, referring to FIG. 3, the outer section 231 of the case connection 23 exposed to the outside of the cabinet 20 is a vertical plane with a cross-section that is a horizontal line segment that extends in the transverse direction, provided that the thickness of the case connection 23 is ignored. And, the length of the horizontal line segment is smaller than the shortest distance of the section of the door seal 10 adjacent to the case connection part 23 from the side panel 211 adjacent to the case connection part 23. For example, the length of the cross section of the outer section 231 of the left cabinet connecting portion 23 in the lateral direction is smaller than the shortest distance of the left section of the door seal 10 from the left side panel 211. Likewise, the length of the cross section of the outer section 231 of the right-side case connection 23 in the lateral direction is smaller than the shortest distance of the right-side section of the door seal 10 from the right-side plate 211.
In other embodiments of the present invention, referring to fig. 5, the outer section 231 of the case connection portion 23 exposed to the outside of the cabinet 20 is a curved surface having an arc shape in cross section, which is convex forward, in the case connection portion 23 with the thickness of the case connection portion 23 omitted. The projection of this arc in a vertical plane perpendicular to the front-to-rear direction (i.e., a plane parallel to the cabinet front opening) has a length in the transverse direction that is less than the shortest distance of the section of the door seal 10 adjacent to the cabinet connecting portion 23 from the side panel 211 adjacent to the cabinet connecting portion 23. For example, the length of the cross section of the outer section 231 of the left cabinet connecting portion 23 projected in the lateral direction in the above-mentioned vertical plane is smaller than the shortest distance of the left section of the door seal 10 from the left side panel 211. Likewise, the length of the cross section of the outer section 231 of the right cabinet connecting portion 23 projected in the lateral direction in the above-mentioned vertical plane is smaller than the shortest distance of the right section of the door seal 10 from the right side plate 211.
It will be appreciated by those skilled in the art that the shape of the outer section 231 of the case connection 23 of the present invention is not limited to the two cases mentioned above, and may be other suitable shapes. From this, improved case shell connecting portion structural design's flexibility.
In some embodiments of the invention, referring to fig. 3 and 5, the case connection 23 further has an inner section 232 hidden inside the cabinet 20, the farthest end of the inner section 232 extending laterally outward and inward does not exceed the location of the beginning of the door seal 10 extending laterally outward and inward adjacent to the case connection 23. For example, the farthest end of the inner section 232 of the case connecting portion 23 located on the left side extending to the right in the lateral direction does not exceed the position of the start end of the left section of the door seal 10 extending to the right in the lateral direction. That is, the farthest end of the inner section 232 of the case connecting portion 23 on the left side extending rightward in the lateral direction is located on the left side of the starting end of the left section of the door seal 10 extending rightward in the lateral direction. Likewise, the farthest end of the inner section 232 of the case connecting portion 23 located on the right side extending in the lateral left direction does not exceed the position of the starting end of the right section of the door seal 10 extending in the lateral left direction. That is, the farthest end of the inner section 232 of the case connecting portion 23 located on the right side, which extends leftward in the lateral direction, is located on the right side of the starting end of the right section of the door seal 10, which extends leftward in the lateral direction.
That is, the inward extension length of the inner section 232 of the cabinet connecting portion 23 is also short, whereby heat leakage at the cabinet 20 due to the heat bridge effect can be further reduced or even avoided, thereby further reducing the loss of cooling energy.
Further, the cross-section of the inner section 232 of the housing connection 23 is curved with multiple bends and/or curves to facilitate a better connection with the inner container 22.
In some embodiments of the present invention, referring to fig. 3 and 5, the inner container 22 has an inner container connecting portion 221 at both lateral sides thereof to respectively cooperate with the two case connecting portions 23 provided at the front portions of the two side plates 211 of the case 21, so that the inner container 22 is fixedly connected to the case 21. The cross section of the inner container connecting part 211 is a curve which is bent and/or curved for multiple times so as to be better matched with the case shell connecting part 23, and therefore, the connection between the case shell 21 and the inner container 22 is firmer and more stable.
In some embodiments of the present invention, the door seal 10 is a demagnetized seal (i.e., no magnetic strip is disposed inside the door seal 10). Therefore, the phenomenon of obvious cold quantity leakage at the position of the door seal 10 can be avoided, the energy consumption of the refrigerating and freezing device 1 is further reduced, and the heat preservation performance of the refrigerating and freezing device 1 is improved.
Further, a rear surface of the opening side of the door 30 and a side of the front surface of the cabinet 20 corresponding to the opening side of the door 30 are provided with a locking mechanism to provide a locking force to the cabinet 20 and the door 30 when the door 30 is closed, so that the two are maintained in a locked state, that is, the door 30 is maintained in a closed state. At this time, a good and reliable airtight seal can be maintained between the door 20 and the door 30 by the pressing contact between the door seal 10 and the door 20.
Specifically, in some embodiments, the locking mechanism may be a magnetic mechanism including magnetically attracting magnets respectively disposed on the door 30 and the compartment 20, and the locking force between the door 30 and the compartment 20 is a magnetic attraction force. Since the magnet of the magnetic mechanism has a small volume, the amount of heat transfer is limited, and the sealing performance of the refrigerating and freezing device 1 is hardly affected. In other embodiments, the locking mechanism may also be a clamping mechanism, which may include clamping members respectively disposed on the box body 20 and the door body 30, and the locking force between the box body 20 and the door body 30 is the clamping force.
In some embodiments of the present invention, the door seal 10 has a mounting portion 110 for mounting it to the door body 30 and an airbag portion 120 for forming an airtight seal between the cabinet 20 and the door body 30. The bag portion 120 has a plurality of air bags arranged symmetrically. When the door seal 10 is pressed (for example, the suction force or the locking force between the refrigerator body 20 and the door body 30 of the refrigeration and freezing device), the air bag portion 120 is deformed relatively uniformly, so that the air bag portion 120 is allowed to be pressed and contacted with the refrigerator body 20 of the refrigeration and freezing device 1 in a balanced and large-area manner, which is beneficial to the airtight sealing between the refrigerator body 20 and the door body 30 of the refrigeration and freezing device 1, and a certain adhesive force can be formed between the air bag portion 120 and the refrigerator body 20, so that the requirement on the suction force between the refrigerator body 20 and the door body 30 is reduced, and the possibility of the door body 30 bouncing is reduced. A large number of experiments prove that the heat leakage quantity of the joint between the doors of the refrigerating and freezing device 1 can be as low as 1.00-1.18W/m, and is reduced by 30% -50% compared with the heat leakage quantity of a door seal adopted by the refrigerating and freezing device in the prior art.
Specifically, the rear surface of the door body 30 may be provided with a groove, and the mounting portion 110 is configured to be inserted into the groove of the door body, so that the door seal 10 is mounted on the door body. The installation part 110 is provided with a barb 111, and the barb 111 is used for being in interference fit with the groove of the door body 30, so that the reliability of connection between the door body of the refrigeration and freezing device 1 and the door seal 10 is improved. The air bag portion 120 is connected to the rear side of the mounting portion 110, and is used to form an airtight seal between the door 30 and the cabinet 20 of the refrigerator-freezer 1.
Fig. 6 is a schematic cross-sectional view of a door seal of a refrigeration freezer in accordance with one embodiment of the present invention. Referring to fig. 6, the airbag section 120 has two symmetrical sub-airbags 121 adjacently disposed at the rear side of the mounting section 110, two symmetrical inner main airbags 122 disposed behind the two sub-airbags 121, and two outer main airbags 123 embracing the two sub-airbags 121 and the two inner main airbags 122 laterally outside.
In addition, since the air bag portion 120 has a plurality of symmetrical main air bags and auxiliary air bags, the interior of the air bag portion 120 forms a multi-layered stacked structural hierarchy and mutual supporting effect. When the door seal 10 is pressed, the auxiliary airbag and the external main airbag not only can play a certain supporting role, but also can greatly improve the elasticity of the airbag portion 120, thereby improving the sealing performance of the door seal 10 and being beneficial to the recovery of the deformation of the airbag portion 120.
Further, each inner main airbag 122 is connected to the outer main airbag 123 on the same side thereof, and is partitioned by a first partition wall 124. I.e. the inner primary airbag 122 and the outer primary airbag 123 on the same side, are connected and separated by a first dividing wall 124. Specifically, the inner main airbag 122 on the left side is connected to the outer main airbag 123 on the left side, and is partitioned by a first partition wall 124; the inner primary airbag 122 on the right is connected to the outer primary airbag 123 on the right and is separated by another first dividing wall 124.
Further, at least partial sections of the two first partition walls 124 extend from front to back in directions away from each other, that is, at least partial sections of the two first partition walls 124 extend from front to back toward both lateral sides of the bag portion 120, respectively. Therefore, in the process that the door seal 10 is squeezed to deform the airbag portion 120, the first partition wall 124 has a smaller effect of blocking the deformation of the airbag portion 120, so that the deformability of the door seal 10 is improved, and the rebound effect of the door seal 10 is reduced to a certain extent. That is, the present invention allows the airbag section 120 to be largely deformed when the door seal 10 receives a small pressing force by specially designing the extending direction and the extending manner of the first dividing wall 124. On one hand, the contact surface between the deformed airbag portion 120 and the box body 20 can be allowed to be flat, and the door seal 10 is prevented from being bounced off the box body, so that the sealing effect is improved; on the other hand, the requirement for the attracting force between the box 20 and the door 30 can be further reduced.
In some embodiments of the invention, each outer primary airbag 123 is connected to the secondary airbag 121 on the same side as it and is separated by a third dividing wall 126. I.e. the outer primary 123 and secondary 121 airbags on the same side are connected and separated by a third partition wall 126. Specifically, the outer primary airbag 123 on the left side and the secondary airbag 121 on the left side are connected and separated by a third partition wall 126; the outer primary airbag 123 on the right side is connected to the secondary airbag 121 on the right side and is separated by another third dividing wall 126.
Further, the two third partition walls 126 extend from front to back in directions away from each other. That is, the two third partition walls 126 extend from front to rear toward both lateral sides of the bag portion 120 to further facilitate deformation of the bag portion 120.
In some embodiments of the present invention, a lower end of each first partition wall 124 is connected to an upper end of a third partition wall 126 located at the same side such that the first partition wall 124 is located at an outer side of the third partition wall 126. This not only improves the strength of the bag portion 120 and facilitates the recovery of deformation, but also allows the upper half portion of the bag portion 120 to be relatively easily deformed.
Fig. 7 is a schematic cross-sectional view of a door seal of a refrigerated freezer according to another embodiment of the invention. Referring to fig. 7, the bag portion 120 has a main bag 127 for press-contacting with the case 20, two inner sub-bags 128 symmetrically disposed in lateral front of the main bag 127, and two outer sub-bags 129 symmetrically embracing laterally outside the main bag 127 and the two inner sub-bags 128. The interior of the airbag portion 120 of this structure also provides a multi-layered structure and mutual supporting effect. When the door seal 10 is pressed, the auxiliary air bag not only can play a certain supporting role, but also can greatly improve the elasticity of the air bag part 120, thereby improving the sealing performance of the door seal 10 and being beneficial to the recovery of the deformation of the air bag part 120.
Further, each inner sub-airbag 128 is connected to the main airbag 127 and is partitioned by a first partition wall 131. The two first partition walls 131 extend from front to back in directions away from each other, that is, the two first partition walls 131 extend from front to back toward both lateral sides of the bag portion 120, respectively. Therefore, in the process that the door seal 10 is squeezed to deform the airbag portion 120, the first partition wall 131 has a smaller effect of blocking the deformation of the airbag portion 120, so that the deformability of the door seal 10 is improved, and the rebound effect of the door seal 10 is reduced to a certain extent. That is, the present invention allows the airbag section 120 to be largely deformed when the door seal 10 receives a small pressing force by specially designing the extending direction and the extending manner of the first partitioning wall 131. On one hand, the contact surface between the deformed airbag portion 120 and the box body 20 can be allowed to be flat, and the door seal 10 is prevented from being bounced off the box body 20, so that the sealing effect is improved; on the other hand, the requirement for the attracting force between the box 20 and the door 30 can be further reduced.
Further, the two first partition walls 131 are connected to form one body having a continuous curved surface, which is convex downward. Specifically, each of the first partition walls 131 has a front end and a rear end at different front-rear positions, and the front ends of the two first partition walls 131 are connected. Thereby, the supporting effect of the two inner auxiliary airbags 128 on the main airbag 127 can be improved to avoid excessive deformation of the bag portion 120.
In some embodiments of the present invention, two internal secondary bladders 128 are connected and separated by a second dividing wall 132 that extends in a fore-aft direction. Therefore, after the air bag portion 120 deforms to a certain extent, the second partition wall 132 can generate a strong supporting effect to prevent the air bag portion 120 from continuing to deform, so that the door seal 10 can be prevented from excessively deforming, and the problem that the door body of a refrigeration and freezing device using the door seal 10 is difficult to open and even cannot be opened normally is solved.
Further, each of the first partition walls 131 is connected to the second partition wall 132. Thereby, the supporting action of the second partition wall 132 can be further strengthened to further prevent the excessive deformation of the bag portion 120.
