Description

Refrigeration device with door hinge assembly
[ technical field ]
The present invention relates to a refrigeration appliance, and more particularly to a refrigeration appliance such as a refrigerator, a wine chest, a freezer, and the like, having a door hinge assembly.
[ background art ]
It is known to adjust the height of a door hinged to the body of a refrigeration appliance relative to the body by means of a door hinge assembly of a height adjustment mechanism, which may vary in height relative to the body. For example, CN102365515A discloses an adjustable hinge assembly for a pivoting door, comprising a pivot shaft fixed to a hinge plate, the pivot shaft having a threaded portion and defining a rotation axis of the door, an adjusting member fitted over the pivot shaft, the adjusting member having internal threads rotatable along the threaded portion of the pivot shaft to adjust the height of the door, and a locking member to maintain the position of the adjusting member along the pivot shaft. During the rotation, the adjusting member moves up and down to move the door up or down. The locking member extends through one of a plurality of recesses provided in the periphery of the adjustment member, and removal of the locking member is required when rotating the adjustment member.
Since the adjustment member is always located next to the bottom of the door, if the operator uses a tool to grip the adjustment member and rotate the adjustment member, the tool will always interfere with the components located above the adjustment member, which can increase the difficulty of height adjustment of the door, which is particularly problematic when the adjustment member is located on the bottom of the refrigerator.
[ summary of the invention ]
The invention aims to provide a refrigeration appliance which is beneficial to reducing the height adjustment difficulty of a door.
Accordingly, one aspect of the present invention pertains to a refrigeration appliance. The refrigerator comprises a main body, a door and a hinge assembly connecting the door and the main body, wherein the hinge assembly comprises a hinge frame with one end fixed to the main body, a hinge shaft connected to the hinge frame and limiting a rotation axis of the door and an adjusting piece used for adjusting the height of the door relative to the main body; the door is characterized by further comprising a top piece sleeved on the hinge shaft and in threaded connection with the adjusting piece, wherein the adjusting piece can rotate in a first direction and drives the top piece to move upwards along the hinge shaft and support the door to move upwards.
Since the adjusting member is rotated to drive the top member screwed with the adjusting member to move upwards when the height of the door relative to the main body needs to be increased, the adjusting member can be kept (at least basically kept) in the original position, which is beneficial to reducing the interference probability between the adjusting member and the bottom of the door, thereby being beneficial to reducing the difficulty of height adjustment of the door. This has the advantages that
The above object is achieved by the features of the independent claims. Preferred embodiments of the invention are the subject of the figures, the description and the dependent claims.
Although it is also possible for the adjusting element to sit on a support surface parallel to the hinge bracket when adjusting the height of the door, according to a particularly preferred embodiment of the invention the adjusting element sits on the hinge bracket when adjusting the height of the door. This is advantageous not only to simplify the structure of the hinge assembly but also to increase the height adjustment range between the door bottom and the hinge bracket.
According to a preferred embodiment of the present invention, when the adjusting member is rotated in a second direction opposite to the first direction, the top member may be moved downward until the top member is seated directly on the hinge bracket.
According to a preferred embodiment of the present invention, the adjusting member may be rotated and moved up to be suspended when the top member is seated on the hinge bracket. Since the top member supporting the door can be directly supported by the hinge bracket, the screw thread between the top member and the adjusting member can no longer bear the weight of the door. This may provide a possibility: that is, when the height of the door does not need to be adjusted, such as during transportation of the refrigeration appliance, the adjuster can be in a suspended/resting state to avoid damage to the threads connecting the adjuster and the top member due to possible up and down fluttering of the door.
According to a preferred embodiment of the present invention, the adjusting member has an internal thread, and the top member is inserted into the adjusting member and has an external thread threadedly coupled with the internal thread.
According to a preferred embodiment of the present invention, the top member includes a cylinder portion inserted into the regulating member and a terrace portion having a larger cross-sectional area than the cylinder portion, the terrace portion forming an upper end surface of the top member. This is advantageous in that the supporting area of the top member to bear the weight of the door is increased.
According to a preferred embodiment of the present invention, a rotation prevention structure is included to prevent the top member from rotating with respect to the hinge shaft. Preferably, the rotation preventing structure may include a slot extending in a rotational axis direction formed by one of the top member and the hinge shaft, and a protrusion formed by the other of the top member and the hinge shaft, protruding from an inner circumferential surface or an outer circumferential surface thereof, and protruding into the slot. Thereby, the top part can be connected with the hinge shaft in a non-rotatable way without adding other parts, and the movement of the top part along the hinge shaft in the vertical direction is guided.
According to a preferred embodiment of the present invention, the refrigeration appliance may include a closing unit between the bottom of the door and the top member.
According to a preferred embodiment of the present invention, the door closing unit includes an upper closing door member fixed to a bottom of the door and a lower closing door member non-rotatably coupled to the top member with respect to the top member, the upper closing door member and the lower closing door member respectively having cam curved surfaces and the pair of cam curved surfaces being in face-to-face contact.
According to a preferred embodiment of the invention, the refrigeration appliance comprises a stop structure for preventing the top piece from moving upwards to the highest position and then moving upwards continuously. This is particularly advantageous for the user/worker to transition to rotating the adjustment member such that the top member and adjustment member are disengaged, or even fall out.
According to a preferred embodiment of the invention, all the threads of the adjustment member and the threads of the top member remain in threaded connection when the top member is moved up to the uppermost position. This is advantageous in order to avoid the situation that only part of the screw thread between the adjusting member and the top member is subjected to the weight of the door and is damaged.
According to a preferred embodiment of the present invention, the stopping structure comprises a first stopping portion connected to the top member and a second stopping portion formed in the adjusting member, and in the highest position, the first stopping portion and the second stopping portion abut against each other to prevent the top member from moving upwards. Thereby avoiding the separation of the adjustment member and the top member in a simple and reliable manner.
According to a preferred embodiment of the present invention, the first stopper is connected to a lower end of the top member.
According to a preferred embodiment of the invention, the first stop is formed by a collar fitted over the top part or integrally formed on the top part.
According to a preferred embodiment of the present invention, the adjusting member is hollow, and includes an adjusting portion having an internal thread and a base portion connected to the adjusting portion, the base portion having an inner diameter larger than the adjusting portion and being formed at a connecting surface connecting an inner peripheral surface of the base portion and the adjusting portion, the second stopper portion being formed by the connecting surface. The second stopping part is integrally and directly formed on the inner wall surface of the adjusting part, so that the number of parts of the hinge assembly is reduced, and the assembly of the hinge assembly is simplified.
According to a preferred embodiment of the invention, the adjustment member step adjusts the height of the door. This is advantageous in order to add a positive feeling to the user/worker who operates the adjustment member regarding the adjusted height.
According to a preferred embodiment of the invention, one of the adjustment member and the hinge bracket is provided with a plurality of recesses spaced around the hinge axis, and the other of the adjustment member and the hinge bracket is provided with at least one protrusion adapted to be at least partially received in either of the recesses. This solution not only prevents the adjustment member from rotating unintentionally relative to the hinge frame, but can also be easily used to form a means of determining the adjustment step of the adjustment member by suitably arranging the concave and convex portions.
The construction of the present invention and other objects and advantages thereof will be more apparent from the following description of the preferred embodiments taken in conjunction with the accompanying drawings.

[ detailed description of the invention ]
Fig. 1 shows a partial perspective view of a refrigeration appliance 100 according to a preferred embodiment of the present invention. As shown in fig. 1, the refrigerator appliance 100 includes a main body 101 having a storage chamber and a pair of doors 102, 102' connected to the main body 101 to close or open the storage chamber. Doors 102, 102' are respectively hinged at left and right sides of the body 101 to open or close the corresponding storage compartments.
The refrigerator appliance 100 includes a hinge assembly 1 connected between a lower end of each door 102, 102' and the main body 101, respectively. The hinge assembly 1 is provided to adjust the height of the corresponding door 102, 102' with respect to the main body 101, respectively. The hinge assembly 1 will be described in detail below by taking the hinge assembly 1 coupled to the door 102 as an example.
FIG. 2 is a schematic partial perspective view of a refrigeration appliance door and hinge assembly assembled together in accordance with a preferred embodiment of the present invention; fig. 3 is a schematic exploded view of a hinge assembly according to a preferred embodiment of the present invention. Referring to fig. 2 and 3 in conjunction with fig. 1, the hinge assembly 1 includes a hinge frame 2 having one end fixed to the main body 101, a hinge shaft 8 fixed to the hinge frame 2 and defining a rotation axis X of the door 102, and an adjusting member 3 for adjusting a height of the door 102 with respect to the main body 101.
The hinge bracket 2 includes a mounting portion 21 fixed to the main body 101. The mounting portion 21 may be provided with a plurality of fixing holes 22 to allow suitable fasteners (not shown) to pass through the mounting portion to secure the hinge bracket to the main body 101. The fixing member may be a screw. In this embodiment, the mounting portion 21 is attached to the bottom surface of the main body 101. In an alternative embodiment, the hinge bracket may also be fixed to the front surface of the main body by appropriately changing the shape of the hinge bracket, which is particularly suitable for the case where the hinge assembly is a center hinge.
The hinge bracket 2 includes a support portion 23 extending forward from the mounting portion 21. The support 23 is perpendicular to the front surface of the main body 101. In this embodiment, the supporting portion 23 and the mounting portion 21 are integral, substantially plate-shaped.
The hinge assembly 1 includes a hinge shaft 8 fixed to the hinge bracket 2, the hinge shaft 8 defining a rotation axis of the door 102. In the present embodiment, the hinge shaft 8 is immovable with respect to the main body 101.
The hinge shaft 8 is fixed to the support 23 and extends vertically upward from the support 23. During the rotation of the door 102, the hinge shaft 8 is not movable relative to the support 23. In this embodiment, the hinge shaft 8 and the support 23 are separately manufactured and then assembled together. Specifically, the hinge shaft 8 passes through a shaft fixing hole 24 on the support 23 and is welded on the support 23.
The hinge frame 8 may include a pair of axis-fixing holes 24 symmetrical with respect to a central axis of a length direction thereof to allow the hinge frame 8 to be simultaneously adapted to be coupled with the doors 102 and 102'.
In an alternative embodiment, the hinge shaft 8 and the support 23 may also form one integral part.
In this embodiment, the hinge shaft 8 is a hollow cylinder with a central hole 80. In an alternative embodiment, the hinge axis may also be a solid cylinder.
The upper end of the hinge shaft 8 protrudes into the door 102 so that the door 102 can rotate about a rotation axis defined by the hinge shaft 8.
The adjusting member 3 is sleeved on the hinge shaft 8 and can rotate around the hinge shaft 8 to adjust the height of the door 102 relative to the main body 101. The adjusting member 3 has a first threaded portion 31 that is an internal thread. The outer peripheral surface of the adjusting member 3 may be configured like a nut to be suitable for the operation of a standard tool such as a wrench.
The adjuster 3 is hollow and includes an adjusting portion 32 whose inner peripheral surface forms a first threaded portion 31. In a preferred embodiment, the adjusting member 3 may further include a base portion 33 connected to a lower end of the adjusting portion 32 and having an inner diameter larger than that of the adjusting portion 32, so that a connecting surface connecting inner circumferential surfaces of the base portion 33 and the adjusting portion 32 is formed therebetween, and the connecting surface forms a second stopper portion 34 for cooperating with a first stopper portion 5 described below.
In this embodiment, the second stop 34 is a substantially annular wall, which may be substantially perpendicular to the axis of rotation X. The inner surface of the base 33 may be smooth.
The hinge assembly 1 includes a top member 4 threadedly coupled with the adjusting member 3. The top member 4 has a through hole 40 penetrating the top member 4 in the rotation axis X direction to fit on the hinge shaft 8, and has a second threaded portion 41 that is an external thread to be engaged with the first threaded portion 31. The second screw portion 41 is formed by a hollow cylindrical portion 42 of the top member 4. In the radial direction, the cylindrical portion 42 is inserted in the adjuster 3 between the hinge shaft 8 and the adjuster 3.
The door 102 is supported by the upper end face of the top member 4. The top member 4 may further have a platform portion 43 for enlarging the upper end surface area of the top member 4.
The top piece 4 is non-rotatably connected to the hinge axis 8 in relation to the hinge axis 8. In this embodiment, the rotation prevention structure to prevent the top member 4 from rotating relative to the hinge shaft 8 includes a groove 81 formed by the hinge shaft 8 and extending in the rotation axis X direction, and a protrusion 44 formed by the top member and protruding from the inner peripheral surface of the through hole 40 and protruding into the groove 81. The projection 44 may extend over the entire axial length of the top piece 4.
In an alternative embodiment, the rotation prevention structure may also include a groove extending in the direction of the rotation axis X formed by the top member, and a protrusion in which the outer peripheral surface of the hinge shaft protrudes and protrudes into the groove.
The hinge assembly 1 may further include a first stopper 5 connected to a lower end of the top member 4. The first stopper portion 5 protrudes outward from the outer peripheral surface of the top member 4, and overlaps the second stopper portion 34 in the direction of the rotation axis X. Thus, the top piece 4 with the first stop 5 cannot enter the hole of the adjustment part 32 of the adjustment piece 3 but can move in the vertical direction within the hole of the base part 33 of the adjustment piece 3.
In a preferred embodiment, the first stop 5 is formed by a collar that is fitted over the top piece 4. The lower end of the cylindrical portion 41 may be formed with a ring of radially recessed retaining grooves 45, and the retainer ring is clamped in the retaining grooves 45 to prevent the retainer ring from moving in the direction of the rotation axis X.
During assembly, the adjusting element 3 may be screwed onto the top element 4, preferably with the end of the top element 4 extending beyond the adjusting element 3, in order to connect the first stop 5 to the lower end of the top element 4. Then, the assembled adjusting member 3, top member 4 and first stopper 5 are fitted over the hinge shaft 8. In this case, the top part 4 can be supported directly on the hinge bracket 2, and the adjusting part 3 can even form a distance with the hinge bracket 2.
The hinge assembly 1 may further include a door closing unit 6 located between the top piece 4 and the bottom of the door 102. The door closing unit 6 may include an upper door closing member 61 immovably fixed to the bottom of the door 102 and a lower door closing member 62 connected to the upper end of the top member 4, the upper door closing member 61 and the lower door closing member 62 having cam curved surfaces, respectively, and the cam curved surfaces being in face-to-face contact.
The lower door closing member 62 is fixed to the top member 4 so as not to be rotatable relative to the top member 4. In a preferred embodiment, holes may be formed in the platform 43 of the bottom closure door 62 and the top member 4, respectively, and a fastener (not shown, such as a screw) may be inserted through the holes and secure the bottom closure door 62 and the top member 4 together. In an alternative embodiment, one or more spaced, projecting tabs may be formed on one of the top member 4 and the lower door closure member 62 and the other of the top member 4 and the lower door closure member 62 may be formed with corresponding recesses/holes to form a bayonet connection, thereby preventing rotation of the top member 4 relative to the lower door closure member 62.
In an alternative embodiment, it may be possible for the lower door closing member 62 to be integrally formed on the top member 4.
The upper door closing member 61 may further include a boss portion 611 to surround the hinge shaft 8.
When the hinge assembly 1 is coupled to the door 102 and the main body 101, the top member 4 may be seated on the hinge bracket 2 to be directly supported by the hinge bracket 2, and the adjusting member 3 and the hinge bracket 2 may form a space therebetween to be in a rest state. Since the weight of the door 102 is directly supported by the hinge bracket 2 at this time, not by the first and second screw parts 31 and 41 which are screw-coupled, this is particularly advantageous in reducing the probability that the first and second screw parts 31 and 41 are damaged due to the door 102 being likely to shake up and down during transportation of the refrigeration appliance 100.
When it is desired to adjust the height of the door 102 relative to the main body 101, the adjustment member 3 can be rotated in a first direction (e.g., clockwise) and the adjustment member 3 moved down the top member 4 until it contacts the hinge bracket 2, as shown in FIG. 4. In this process, the top member 4 is kept stationary, and the height of the door 102 supported by the top member 4 with respect to the main body 101 is also constant, while the top member 4 and the door 102 are both at the lowest position of the door adjustment range determined by the adjusting member 3.
After the adjusting member 3 is seated to the hinge bracket 2, the adjusting member 3 is in an adjusting state in which the height of the door 102 is adjustable. If the adjusting member 3 is continued to be rotated in the first direction, the adjusting member 3 remains seated on (i.e., remains in contact with) the hinge bracket 2 and drives the top member 4 upward along the hinge shaft 8 via the engagement of the first threaded portion 31 and the second threaded portion 41 to move upward against the door 102. In this process, the distance between the top member 4 and the hinge bracket 2 is gradually increased, and the door 102 is gradually raised.
When the top member 4 moves upward until the first stopping portion 5 moving upward along with the top member 4 contacts the second stopping portion 34 of the adjusting member 3, the top member 4 cannot move upward any more, and the adjusting member 3 seated on the hinge bracket 2 cannot rotate in the first direction any more. As shown in fig. 5, the top member 4 is moved upward to a maximum height. The top member 4 and the door 102 are adjusted to the highest position of the door adjustment range determined by the adjusting member 3.
Preferably, all threads of first threaded portion 31 and threads of second threaded portion 41 remain threadedly connected when top member 4 is moved up to the maximum limit height.
When it is required to lower the height of the door 102, the adjusting member 3 seated on the hinge bracket 2 is rotated in a second direction (e.g., counterclockwise) opposite to the first direction, and the top member 4 is driven to move down along the hinge shaft 8, thereby moving the door 102 supported on the top member 4 downward together. When the lower end of the top member 4 and the hinge bracket 2 are in direct contact, the top member 4 and the door 102 supported by the top member 4 reach the lowermost position.
When the top member 4 is seated directly on the hinge bracket 2, if the adjusting member 3 is continuously rotated in the second direction, the adjusting member may move upward along the second screw portion 41 of the top member 4 to be spaced apart from the hinge bracket 2 to be suspended, and the top member 4 remains seated on the hinge bracket 2. At this point, the adjusting member 3 is in a rest condition, the top member 4 being held in a lowermost position. As described above, rotating the adjuster 3 in the first direction causes the suspended adjuster 3 to move down the top member 4 until it contacts the hinge bracket 2.
According to the embodiment of the present invention, when the height of the door 102 is adjusted, the adjusting member 3 is always in contact with the hinge bracket 2, and the driving top member 4 moves up or down in the direction of the rotation axis X; furthermore, when the top member 4 reaches the lowest position, the top member 4 can be seated on the hinge bracket 2, and if the adjusting member 3 is rotated in a predetermined direction, the adjusting member 3 can move up to a suspended state along the immovable top member 4 without bearing the weight of the door 102, which is advantageous for preventing the screw threads of the adjusting member 3 and the top member 4 from being damaged, for example, during transportation; when the top member 4 moves up to the first and second stoppers 5 and 34, the top member 4 cannot move up any more, which prevents the adjusting member 3 and the top member 4 from falling off due to excessive rotation of the adjusting member 3.
The hinge assembly 1 may also be configured such that the adjuster 3 adjusts the height of the door 102 step by a predetermined step. In a preferred embodiment, referring to fig. 3 to 6, the upper surface of the hinge bracket 2 has a plurality of recesses 25 spaced around the shaft fixing hole 24. The recesses 25 may be distributed in a common concentric ring. The lower end surface of the adjusting member 3 is provided with a plurality of protrusions 35, and each protrusion 35 can be at least partially received in any one of the recesses 25. In an alternative embodiment, the adjusting element 3 can also be provided with only one projection 35 or two projections 35 which are arranged symmetrically with respect to the central axis of the adjusting element 3.
When the adjusting member 3 is rotated, each of the convex portions 35 is moved out of the original concave portion 25 and rotated along the upper surface of the hinge bracket 2 until it falls into the concave portion 25 adjacent to the original concave portion 25, which gives a user/worker who operates the adjusting member a distinct indication feeling.
These recesses 25 are distributed at the same intervals. In the embodiment shown in fig. 3, there are six recesses 25 distributed at equal intervals for each shaft fixing hole 24.
As shown in fig. 6, each of the projections 35 preferably has an inverted conical shape with a rounded transition at the apex. The recess 25 may also be configured as an inverted cone adapted to mate with the protrusion 35.
Further, since the height of the door 102 can be adjusted step by a predetermined margin by the adjusting member 3 with the convex portion 35 and the concave portion 25 in the plug-in connection, the adjusting member 3 does not rotate without a large rotational force being applied to the adjusting member 3, that is, the adjusting member 3 can be prevented from rotating unexpectedly.
In an alternative embodiment, it is also possible to form the recess on the lower end surface of the adjusting member and the projection on the hinge bracket.
In the above embodiment, the first stopper portion 5 is assembled as a separate member on the top piece 4. However, in an alternative embodiment, it is also possible for the first stop to be formed integrally on the top part 4.
The various embodiments of the individual components described in connection with fig. 1 to 6 may be combined with each other in any given way to achieve the advantages of the invention. In addition, the present invention is not limited to the illustrated embodiments, and other means than those shown may be generally used as long as the same effects are obtained.
