Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a hinge and a refrigeration device having the hinge. Background Technology

[0002] Refrigeration equipment such as refrigerators, freezers, and wine cabinets typically use hinges to connect the door and the cabinet to open or close the door.

[0003] However, refrigeration equipment is often used in places with high traffic such as shopping malls, supermarkets, and stores. Due to frequent opening and closing, users may close the door casually after opening it. In this case, the door may not close tightly, leaving gaps between the door and the cabinet. This not only easily leads to the leakage of cold air and increased energy consumption, which is not conducive to energy conservation and environmental protection, but also makes it easy for the items stored in the refrigeration equipment to have odors mixed with the outside environment. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a hinge and a cooling device to solve the problem that existing hinges cannot seal the door and cabinet when the door is closed.

[0005] To achieve one of the above-mentioned objectives of this utility model, one embodiment of this utility model provides a hinge, comprising:

[0006] A cabinet hinge seat has a cabinet mounting surface, which is assembled to the cabinet.

[0007] A door hinge seat is assembled to the door body and pivotally connected to the cabinet hinge seat via a pivot shaft. The door hinge seat has a closed position to close the cabinet.

[0008] The swing shaft is fixedly connected to the door hinge seat and parallel to the pivot shaft;

[0009] A sliding shaft is slidably connected to the cabinet hinge seat and parallel to the pivot shaft;

[0010] A connector that simultaneously pivotally connects the swing shaft and the sliding shaft;

[0011] The support member supports the sliding shaft to move linearly from bottom to top;

[0012] When the door hinge is in the closed position, the axis of the swing shaft is located on the side opposite to the mounting surface of the cabinet, and the swing shaft is located below the pivot shaft.

[0013] As a further improvement of one embodiment of the present invention, the axis of the swing shaft and the axis of the pivot shaft form a first plane, and when the door hinge seat is in the closed position, the angle θ between the first plane and the up and down direction satisfies: 0° < θ ≤ 40°.

[0014] As a further improvement of one embodiment of the present invention, the axis of the sliding shaft and the axis of the pivot shaft form a second plane, and when the door hinge seat is in the closed position, the swing shaft is located on the side of the second plane away from the cabinet mounting surface.

[0015] As a further improvement of one embodiment of the present utility model, the door hinge seat has an opening position for opening the cabinet. When the door hinge seat is in the opening position, the swing axis is located on the side of the second plane facing the cabinet mounting surface.

[0016] As a further improvement of one embodiment of the present invention, the hinge includes a limiting part, which restricts the sliding shaft from making linear movements in the up-down direction.

[0017] As a further improvement of one embodiment of the present utility model, the limiting part includes a sliding groove extending vertically, the sliding groove is disposed in the cabinet hinge seat, and the sliding shaft is connected in the sliding shaft and can move vertically along the sliding groove.

[0018] As a further improvement of one embodiment of the present invention, the support member is an elastic member, and the sliding groove has a limit proximal end near the door hinge seat and a limit distal end away from the door hinge seat; when the door hinge seat is in the closed position and the sliding shaft is located at the limit distal end, the elastic member has a first compression deformation.

[0019] As a further improvement of one embodiment of the present utility model, the door hinge seat has an opening position for opening the cabinet. When the door hinge seat is in the opening position, there is a first gap between the sliding shaft and the limit proximal end. The elastic element has a second compression deformation, and the first compression deformation is greater than the second compression deformation.

[0020] As a further improvement of one embodiment of the present invention, the elastic element includes a support rod and a spring sleeved on the outer periphery of the support rod. One end of the support rod is connected to the sliding shaft, and the other end of the support rod is inserted into the cabinet hinge seat and can move up and down relative to the cabinet hinge seat. A limiting protrusion is provided at the end of the support rod near the sliding shaft. The end of the spring near the sliding shaft abuts against the limiting protrusion, and the other end of the spring away from the sliding shaft abuts against the cabinet hinge seat.

[0021] To achieve one of the above-mentioned objectives of the utility model, one embodiment of the utility model also provides a refrigeration device, including a cabinet and a door assembled on the cabinet, and further including the hinges as described above, wherein the cabinet hinge seat is connected to the cabinet and the door hinge seat is connected to the door.

[0022] Compared with the prior art, the present invention has the following beneficial effects: When the hinge seat of the present invention is in the closed position, that is, when the door is closed, through the connection relationship between the various components and the fact that the axis of the swing shaft is located on the side opposite to the axis of the pivot shaft away from the mounting surface of the cabinet, under the action of the support member, the sliding shaft provides an upward support force to the swing shaft through the connecting member. Thus, when the door is closed, it has a tendency to drive the hinge seat of the door to move downward, thereby driving the door to press down, which is beneficial to the sealing of the door and the cabinet and improves the sealing performance of the refrigeration equipment.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings.

[0030] In the various illustrations of this utility model, for ease of illustration, some dimensions of the structure or part may be enlarged relative to other structures or parts. Therefore, they are only used to illustrate the basic structure of the subject matter of this utility model.

[0031] It should be understood that although the terms first, second, etc., may be used in this document to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another.

[0032] See Figure 1 The refrigeration device 100 provided in one embodiment of this utility model includes a hinge 1, a cabinet 2, and a door 3. The cabinet 2 encloses a refrigeration compartment for storing and refrigerating items. The door 3 is assembled to the cabinet 2 and can rotate relative to the cabinet 2 to open or close the refrigeration compartment. The refrigeration device 100 can be specifically configured as a refrigerator, freezer, wine cabinet, etc., especially a large-capacity or ultra-thin refrigeration device 100.

[0033] The door 3 is connected to the cabinet 2 by a hinge 1, which supports the opening and closing of the door 3.

[0034] Hinge 1 includes a cabinet hinge seat 10 and a door hinge seat 20, with the door hinge seat 20 rotatably connected to the cabinet hinge seat 10 via a pivot shaft 30. The cabinet hinge seat 10 is assembled to the cabinet 2, and the door hinge seat 20 is assembled to the door 3. When the door 3 opens or closes the refrigeration compartment, under the action of an external force, the door 3 rotates relative to the cabinet 2. The door hinge seat 20 assembled to the door 3 rotates relative to the cabinet hinge seat 10, thereby causing the door 3 to rotate relative to the cabinet 2 to open or close the refrigeration compartment.

[0035] Specifically, the cabinet hinge seat 10 can be fixedly connected to the cabinet 2 by screws or other assembly structures. The cabinet hinge seat 10 has a cabinet mounting surface, which is assembled to the cabinet 2. The door hinge seat 20 can be fixedly connected to the door 3 by screws or other assembly structures.

[0036] Specifically, the pivot shaft 30 can be fixedly connected to one of the cabinet hinge seat 10 and the door hinge seat 20, and pivotally connected to the other. In this embodiment, the pivot shaft 30 is fixedly connected to the cabinet hinge seat 10 and pivotally connected to the door hinge seat 20. In other embodiments, the pivot shaft 30 can also be fixedly connected to the door hinge seat 20 and pivotally connected to the cabinet hinge seat 10.

[0037] To clearly illustrate the positional relationships, this embodiment uses the example of the refrigeration device 100 being placed horizontally on the ground. With the door 3 closed, the direction from the door 3 to the cabinet 2 is defined as the top-to-bottom direction, meaning the door 3 is located above the cabinet 2. Correspondingly, the door hinge seat 20 is located above the cabinet hinge seat 10. The direction from the hinge 1 to the cabinet 2 is defined as the back-to-front direction, meaning the hinge 1 is located behind the cabinet 2, while the door 3 flips open from the front of the cabinet 2. When the user faces the cabinet 2 from the front, the two sides of the hinge 1 are defined as left and right, respectively.

[0038] The door hinge seat 20 has an open position for opening the cabinet 2 and a closed position for closing the cabinet 2, which correspond to the closed state and open state of the door 3, respectively. The closed state means that the door 3 is fastened to the cabinet 2, thereby sealing the refrigeration compartment. At this time, the position of the door hinge seat 20 relative to the cabinet hinge seat 10 is the closed position. The open state means that the door 3 is separated from the cabinet 2 except for the side connected to the hinge 1. After the external force is removed, the door 3 can stop on its own. At this time, the refrigeration compartment is exposed to the air. At this time, the position of the door hinge seat 20 relative to the cabinet hinge seat 10 is the open position.

[0039] See Figures 2 to 3 The hinge 1 includes a swing shaft 40, a sliding shaft 50, a connector 60, and a support 70. The swing shaft 40 is fixedly connected to the door hinge seat 20 and parallel to the pivot shaft 30. The sliding shaft 50 is slidably connected to the cabinet hinge seat 10 and parallel to the pivot shaft 30. The connector 60 pivotally connects the swing shaft 40 and the sliding shaft 50. The support 70 is connected to the sliding shaft 50 and supports the sliding shaft 50 to move linearly from bottom to top.

[0040] In this way, as the door hinge seat 20 rotates relative to the cabinet hinge seat 10 around the pivot axis 30, the swing shaft 40 connected to the door hinge seat 20 swings accordingly. When the swing shaft 40 swings, the traction connector 60 drives the sliding shaft 50 to move together. Since the three axes of the swing shaft 40, pivot axis 30 and sliding shaft 50 are parallel to each other, when the door hinge seat 20 rotates around the pivot axis 30, the sliding shaft 50 is always parallel to the pivot axis under the constraint of each component, and moves in a straight line from bottom to top under the action of the support 70.

[0041] Combination Figure 4 When the door hinge seat 20 is in the closed position, the axis of the swing shaft 40 is located on the side of the pivot shaft 30 away from the cabinet mounting surface, and the swing shaft 40 is located below the pivot shaft 30, that is, the axis of the swing shaft 40 is located behind and below the axis of the pivot shaft 30. The axis of the swing shaft 40 and the axis of the pivot shaft 30 form a first plane. When the door hinge seat 20 is in the closed position, that is, when the door 3 is in the closed state, the first plane is at an angle to the vertical direction. Since the swing shaft 40 is located behind the pivot shaft 30, under the action of the support member 70, the sliding shaft 50 provides an upward support force to the swing shaft 40 through the connecting member 60. Therefore, when the door 3 is in the closed state, it has a tendency to drive the door hinge seat 20 to move downward, thereby driving the door 3 to press downward, which is beneficial to the sealing of the door 3 and the cabinet 2 and improves the sealing performance of the refrigeration equipment 100.

[0042] Preferably, when the door hinge seat 20 is in the closed position, the angle θ between the first plane and the vertical direction satisfies 0° < θ ≤ 40°. Within this angle range, not only can the refrigeration equipment 100 have excellent sealing performance, but it can also prevent the swing shaft 40 from deviating too far from the pivot shaft 30, which would result in a larger thickness of the hinge 1 and thus increase the rear space required by the hinge 1, thereby avoiding a reduction in the packing weight and volume ratio of the refrigeration equipment 100.

[0043] Furthermore, the axis of the sliding shaft 50 and the axis of the pivot shaft 30 form a second plane. When the door hinge seat 20 is in the closed position, the swing shaft 40 is located on the side of the second plane away from the cabinet mounting surface. Therefore, under the action of the support member 70, the sliding shaft 50 provides an upward and backward supporting force to the swing shaft 40 through the connecting member 60. Thus, when the door 3 is in the closed state, it has a tendency to drive the door hinge seat 20 to move forward and downward, thereby driving the door 3 to press downward, which is beneficial to the sealing of the door 3 and the cabinet 2 and improves the sealing performance of the refrigeration equipment 100.

[0044] Combination Figure 5 When the door hinge seat 20 is in the open position, the swing shaft 40 is located on the side of the second plane facing the cabinet mounting surface. Thus, after the door 3 is opened to a certain angle, under the action of the support member 70, the sliding shaft 50 provides an upward and forward supporting force to the swing shaft 40 through the connecting member 60, thereby driving the door hinge seat 20 to rotate backward, achieving the effect of making opening the door easier.

[0045] See Figure 5 When the door hinge seat 20 is in the open position, the swing shaft 40 is located on the side of the pivot shaft 30 facing the cabinet mounting surface.

[0046] In other words, during the process of the door 3 changing from the closed state to the open state, that is, during the rotation of the door hinge seat 20 from the closed position to the open position, the swing shaft 40 rotates from the side of the second plane away from the cabinet mounting surface to the side facing the cabinet mounting surface, while the swing shaft 40 swings from the rear side of the pivot shaft 30 to the front side. Thus, the sliding shaft 50 and the support member 70 can be located at the midpoint of the thickness of the cabinet hinge seat 10 along the front-back direction, and the pivot shaft 30 can be located at the midpoint of the thickness of the door hinge seat 20 along the front-back direction. This avoids the situation where the sliding shaft 50 and the support member 70 are located at the rear end of the cabinet hinge seat 10, resulting in a large thickness or insufficient strength of the hinge 1 along the front-back direction, and also avoids the situation where the pivot shaft 30 is located at the rear end of the door hinge seat 20, resulting in a large thickness or insufficient strength of the hinge 1 along the front-back direction.

[0047] Furthermore, the hinge 1 also includes a limiting part, which restricts the sliding shaft 50 from making linear movements in the up-down direction. The limiting part can be set on the cabinet hinge seat 10, or on the encapsulation cover plate of the hinge 1, or it can be set in multiple places at the same time. Its function is to restrict the movement of the sliding shaft 50, so that it can only make linear movements under the traction of the connecting member 60. The pivot shaft 30, the door hinge seat 20, the swing shaft 40, the connecting member 60, the sliding shaft 50 and the limiting part together constitute a crank-slider mechanism, which converts the rotation of the door hinge seat 20 into the linear movement of the sliding shaft 50.

[0048] Combination Figures 2 to 3 Specifically, in this embodiment, the limiting part includes a sliding groove 80 extending vertically. The sliding groove 80 is provided in the cabinet hinge seat 10, and the sliding shaft 50 is connected in the sliding shaft 50 and can move vertically along the sliding groove 80.

[0049] The cabinet hinge base 10 includes a base plate 11 abutting against the outer wall of the cabinet 2 and a pair of side plates 12 arranged opposite each other. The pair of side plates 12 are located on the side of the base plate 11 away from the cabinet 2. The pair of side plates 12 are respectively connected to the left and right ends of the base plate 11 and extend in the same direction. Specifically, in this embodiment, the pair of side plates 12 extend backward from the base plate 11. The base plate 11 has a cabinet mounting surface, and is assembled to the cabinet 2 through the cabinet mounting surface, thereby assembling the cabinet hinge base 10 to the cabinet 2.

[0050] In this embodiment, a pair of sliding grooves 80 are arranged opposite each other, and the pair of sliding grooves 80 are respectively arranged on a pair of side plates 12. The two ends of the sliding shaft 50 are respectively matched in the pair of sliding grooves 80.

[0051] In other embodiments, the sliding groove 80 can also be provided on the base plate 11, and the sliding shaft 50 is provided with a mating part that engages with the sliding groove 80, which can also enable the sliding shaft 50 to move up and down along the sliding groove 80.

[0052] The support member 70 is an elastic member, and the sliding groove 80 has a proximal end near the door hinge seat 20 and a distal end far from the door hinge seat 20. When the door hinge seat 20 is in the closed position and the sliding shaft 50 is at the distal end, the elastic member has a first compression deformation. Thus, due to the first compression deformation of the elastic member, when the door 3 is closed, the elastic member provides an upward supporting force to the sliding shaft 50 due to its elastic restoring force. This force is transmitted to the swing shaft 40 through the connector 60, tending to drive the door hinge seat 20 downwards, thereby driving the door 3 to press downwards, which is beneficial for the sealing of the door 3 and the cabinet 2, and improves the sealing performance of the refrigeration equipment 100.

[0053] When the door hinge seat 20 is in the open position, there is a first gap between the sliding shaft 50 and the near end of the limit, and the elastic element has a second compression deformation. Thus, when the door hinge seat 20 is in the open position, that is, when the door 3 is in the open state, the elastic element provides an upward supporting force to the sliding shaft 50 due to the elastic restoring force. Since the swing shaft 40 is located in front of the pivot shaft 30 at this time, the supporting force of the elastic element is transmitted to the swing shaft 40 through the connecting member 60, which has the tendency to drive the door hinge seat 20 to move backward and downward, thus achieving the technical effect of the door 3 being suspended in the open state.

[0054] Furthermore, the first compression deformation is greater than the second compression deformation. That is to say, during the process of the door 3 changing from the closed state to the open state, that is, during the process of the door hinge seat 20 rotating from the closed position to the open position, the elastic element is always in a compressed state.

[0055] See Figures 2 to 3 Furthermore, in this embodiment, the elastic element includes a support rod 71 and a spring 72 sleeved on the outer periphery of the support rod 71. One end of the support rod 71 is connected to the sliding shaft 50, and the other end of the support rod 71 away from the sliding shaft 50 is inserted into the cabinet hinge seat 10 and loosely connected to the cabinet hinge seat 10. That is, the support rod 71 can move up and down relative to the cabinet hinge seat 10. A limiting protrusion is provided at the end of the support rod 71 near the sliding shaft 50. The end of the spring 72 near the sliding shaft 50 abuts against the limiting protrusion, and the other end of the spring 72 away from the sliding shaft 50 abuts against the cabinet hinge seat 10.

[0056] See Figures 2 to 3 Furthermore, the cabinet hinge seat 10 includes an end stop 13, which has a slot. The end of the elastic element away from the movable shaft is inserted into the slot, thereby limiting the elastic element to move only parallel to the base plate 11, that is, up and down, thus avoiding increasing the thickness of the hinge 1. In this embodiment, the lower end of the spring 72 abuts against the end stop 13, and the lower end of the support rod 71 is inserted into the slot. The inner diameter of the slot is larger than the outer diameter of the support rod 71, that is, the support rod 71 is loosely connected to the end stop 13. When the elastic element moves up and down synchronously with the movable shaft, the lower end of the support rod 71 always protrudes from the end stop 13, which can prevent the elastic element from falling out of the end stop 13 and causing the elastic element to fail.

[0057] See Figures 2 to 3 In this embodiment, the end stop 13 is a U-shaped plate, and the cabinet hinge seat 10 also includes a pair of protrusions 14. The pair of protrusions 14 are respectively provided on a pair of side plates 12 and protrude toward each other. The opening of the U-shaped plate faces the pair of protrusions 14, and the pair of protrusions 14 are both engaged in the opening of the U-shaped plate. The combined action of the spring 72 and the protrusions 14 restricts the movement of the U-shaped plate relative to the side plates 12, especially restricts the up and down movement of the U-shaped plate.

[0058] In other embodiments, the end stop 13 may also be configured as a baffle embedded in a pair of side plates 12, and the baffle is perpendicular to the side plates 12, thereby restricting the movement of the baffle relative to the side plates 12, especially restricting the up-and-down movement of the baffle.

[0059] Furthermore, during the rotation of the door hinge seat 20 from the closed position to the open position, the connecting member 60 and the base plate 11 do not interfere with each other. Preferably, the connecting member 60 and the cabinet hinge seat 10 do not interfere with each other. Specifically, this can be achieved by setting the distance between the base plate 11 and the base plate.

[0060] Furthermore, when the door hinge seat 20 is in the open position, the axis of the swing shaft 40 is located on the plane of the base plate 11, or the axis of the swing shaft 40 is located on the side of the plane of the base plate 11 away from the side plate 12. This avoids mechanical interference between the swing shaft 40, the connector 60 and the base plate 11 and the cabinet 2.

[0061] Compared with the prior art, the hinge 1 and refrigeration device 100 provided by this utility model have the following advantages: when the door hinge seat 20 is in the closed position, that is, when the door 3 is closed, through the connection relationship between the components and the fact that the axis of the swing shaft 40 is located on the side opposite to the axis of the pivot shaft 30 to the cabinet mounting surface, under the action of the support member 70, the sliding shaft 50 provides an upward support force to the swing shaft 40 through the connecting member 60. Thus, when the door 3 is closed, it has a tendency to drive the door hinge seat 20 to move downward, thereby driving the door 3 to press downward, which is beneficial to the sealing of the door 3 and the cabinet 2 and improves the sealing performance of the refrigeration device 100.
