Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, refrigerators and freezers have refrigeration compartments that create a refrigerated environment for storing goods.

[0003] The refrigerator door is hinged to the refrigerator shell, allowing the corresponding cooling compartment to be opened. However, in actual production and use, insufficient hinge precision or door deformation during use can cause uneven heights in the left and right directions, significantly affecting the refrigerator's aesthetics.

[0004] Currently, the main method to achieve consistent door height in the left and right directions is to adjust the hinge dimensions or the pre-installation precision of the foam box. However, the existing adjustment methods are quite complex, require high-precision adjustment processes, and are costly. Utility Model Content

[0005] Based on existing technology, a cooling device is provided to simply and quickly solve the problem of inconsistent height of the door in the left and right directions.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; the housing having a refrigeration compartment; a door hinged to the housing on one side to open or close the refrigeration compartment; and an adjustment seat disposed on the door, the adjustment seat including: a connecting portion disposed on the side wall of the door facing the refrigeration compartment; the connecting portion and the hinge of the door being spaced apart in the width direction of the door; and a support portion, one end of which is connected to the connecting portion, and the other end of which extends toward the side close to the housing; when the door closes the refrigeration compartment, the bottom wall of the support portion supports the top wall of the housing.

[0008] The above technical solution has the following advantages or beneficial effects: By setting an adjustment seat on the side wall of the door facing the refrigeration compartment, the adjustment seat includes a connecting part and a supporting part. The connecting part is connected to the inside of the door and plays a positioning role for the supporting part, so that the supporting part can always accurately correspond to the top wall of the cabinet. One end of the supporting part is connected to the connecting part, and the other end extends towards the cabinet. Since the end of the door away from the hinge with the cabinet is prone to sinking, by setting the supporting part, the door is supported by the top wall of the cabinet when the refrigeration compartment is closed. In this way, the side of the door away from the hinge can be lifted up by the reaction force of the top wall of the cabinet, thereby offsetting the sinking of the right side and making the height of the left and right sides of the door more consistent. Compared with the prior art, which requires adjusting or replacing the hinge structure, this application only needs to install an adjustment seat on the inside of the door. The adjustment seat can compensate for the accuracy deviation of the door hinge structure and correct the height of the left and right sides of the door through the supporting part, solving the problem of structural complexity and increased cost caused by adjusting the hinge again and setting high-precision hinges before leaving the factory. Meanwhile, due to the simple structure and fewer parts of the adjustment seat, the manufacturing cost is greatly reduced compared to high-precision hinges. Furthermore, the length of the support and the size of the connection can be flexibly adjusted according to different door sizes, making it highly versatile and eliminating the need for separate design for different models of refrigeration units, thus further controlling production costs.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein a guide wall is provided at one end of the support portion away from the connecting portion, the lower end of the guide wall is connected to the bottom wall of the support portion, and the upper end of the guide wall is connected to the top wall of the support portion; in the direction from bottom to top, the guide wall extends upward at an angle toward the side closer to the housing.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: By providing a guide wall at the end of the support part away from the connecting part, the guide wall is inclined from bottom to top towards one side of the box. When the door closes to the point where the support part approaches the top wall of the box, the front end of the guide wall will first contact the top wall of the box. The inclined guide wall will form a guiding slope. Even if there is a slight deviation between the initial movement direction of the support part and the top wall of the box, the inclined guide wall can gradually guide the door to move upward. Furthermore, the reaction force generated by the contact between the guide wall and the top wall of the box can effectively adjust the position of the support part, thereby enabling the bottom wall of the support part to fit completely against the top wall of the box. This not only makes the closing process smoother and without abrupt jamming, but also effectively reduces the risk of the support part getting stuck at the edge of the box due to misalignment.

[0011] In some embodiments of this application, a refrigeration device is provided, wherein the adjusting seat is located on the side of the door away from the hinged connection with the box body.

[0012] Another technical solution described above has the following advantages or beneficial effects: By placing the adjusting seat near the side of the door away from the hinge, when the door closes the refrigeration compartment, the support rests on the top wall of the cabinet, directly supporting the free side of the door as it sinks. Furthermore, the adjusting seat on the side of the door away from the hinge provides additional support, increasing the door's stability in that direction and distributing the force on the door more evenly across the cabinet, thus preventing excessive local stress on the door or cabinet due to concentrated force.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein the side wall of the door facing the refrigeration chamber is provided with a positioning groove, and the connecting part is embedded in the positioning groove to be fixed on the door.

[0014] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting a positioning groove on the side wall of the door facing the refrigeration room, the positioning groove can provide precise positioning for the installation of the adjustment seat on the door. During the installation process, the connecting part can be accurately embedded in the positioning groove, avoiding the adjustment seat from shifting in the left or right or up or down direction on the door, ensuring that the relative position of the adjustment seat and the door is fixed, thereby improving the stability of the adjustment seat supporting the door.

[0015] In some embodiments of this application, a refrigeration device is provided, wherein a positioning hole is provided in the positioning groove and the positioning hole communicates with the positioning groove; a positioning post is provided on the side of the connecting part facing the door body, the positioning post is correspondingly provided with the positioning hole, and the positioning post is inserted into the positioning hole.

[0016] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: In order to further improve the quick installation and installation accuracy of the adjustment seat and the door body, a positioning hole is opened in the positioning groove, and a positioning hole corresponding to the positioning hole is provided in the connecting part. When the adjustment seat and the door body are assembled, the relative position of the positioning post and the positioning hole can be used to provide a guiding reference for the installation, so as to avoid the connecting part from being tilted to the left or right or misaligned to the front or back during the installation process. Moreover, during the opening and closing of the door body, the adjustment seat may be subjected to a certain torque. The positioning post is inserted into the positioning hole, which can effectively limit the rotation of the connecting part in the horizontal plane, making the connection between the adjustment seat and the door body more stable.

[0017] In some embodiments of this application, a refrigeration device is provided, wherein the adjusting seat further includes a first reinforcing rib, the first reinforcing rib is disposed at the bottom of the support portion, the first reinforcing rib is connected between the connecting portion and the bottom wall of the support portion, the side of the first reinforcing rib near the door body is connected to the connecting portion, and the top end of the first reinforcing rib is connected to the bottom wall of the support portion.

[0018] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by connecting the first reinforcing rib to the bottom wall of the connecting part and the support part, part of the force on the support part can be transmitted to the connecting part along the support part itself, and another part of the force can be transmitted directly to the connecting part through the first reinforcing rib, thereby avoiding the support part from breaking or being damaged due to stress concentration, and further improving the structural strength of the support part.

[0019] In some embodiments of this application, a refrigeration device is provided, wherein a door seal is provided on the side wall of the door facing the refrigeration compartment, and the door seal is disposed around the periphery of the door; when the door closes the refrigeration compartment, the door seal is clamped between the door and the front side wall of the housing, and the first reinforcing rib is located between the outer periphery of the door seal and the front side wall of the housing.

[0020] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting the first reinforcing rib between the outer periphery of the door seal and the front side wall of the box, the interference problem between the first reinforcing rib and the door seal during the opening and closing process can be avoided. When the door is closed, the support part can smoothly contact the top wall of the box and achieve stable support, which is conducive to the adjustment seat being able to play its role in adjusting the height of the door normally, and its functional stability will not be affected by the interference of the door seal.

[0021] In some embodiments of this application, a refrigeration device is provided, wherein the adjusting seat further includes a second reinforcing rib, the second reinforcing rib is disposed at the top of the support portion, the second reinforcing rib is connected between the connecting portion and the top wall of the support portion, the side of the second reinforcing rib near the door body is connected to the connecting portion, and the bottom end of the second reinforcing rib is connected to the top wall of the support portion.

[0022] Another technical solution described above has the following advantages or beneficial effects: By connecting the second reinforcing rib to the bottom wall of the connecting part and the supporting part, when the door closes the refrigeration compartment, the supporting part rests on the top wall of the cabinet, and its bottom wall bears the upward reaction force. At this time, the second reinforcing rib located at the top of the supporting part can bear the tensile stress. Specifically, when the supporting part is subjected to force and bends outwards towards the cabinet, the tensile force generated at the top of the supporting part can be transmitted to the connecting part through the second reinforcing rib. Simultaneously, in conjunction with the first reinforcing rib at the bottom to share the stress, the stress on the first reinforcing rib when it rests on the top of the cabinet can be effectively reduced, while also reducing the risk of damage to the supporting part due to tension at the top. Moreover, the combined arrangement of the first and second reinforcing ribs can effectively strengthen the structural strength of the supporting part, enhance the overall bending rigidity of the supporting part, and prevent insufficient support force due to deformation of the bottom wall of the supporting part, thus affecting the door height correction effect.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein when the door closes the refrigeration compartment, the first reinforcing rib is spaced apart from the front wall of the housing, and the end of the second reinforcing rib away from the connecting portion extends and is arranged above the support area of ​​the support portion and the top wall of the housing.

[0024] Another technical solution described above has the following advantages or beneficial effects: by arranging the first reinforcing ribs at intervals on the front side of the front wall of the housing, the problem of interference and collision between the ends of the first reinforcing ribs and the housing is effectively avoided, reducing the risk of wear on the first reinforcing ribs and the adjustment seat as a whole. On the other hand, the interval arrangement of the first reinforcing ribs and the front wall of the housing can accommodate manufacturing errors of the adjustment seat and the housing. Even if there are local unevennesses on the front wall of the housing, the first reinforcing ribs will not be directly squeezed, allowing the first reinforcing ribs to stably transmit the stress from the support.

[0025] In some embodiments of this application, a refrigeration device is provided, wherein there are two doors arranged adjacent to each other, one door is hinged to one side of the housing, and the other door is hinged to the other side of the housing; there are two adjustment seats, one for each of the two doors, the adjustment seats are arranged on the side of the door away from the hinged side of the housing, and the bottom walls of the support portions of the two adjustment seats are located at the same height of the housing.

[0026] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: By setting two adjustment seats on the left and right doors away from the hinge side, and the bottom walls of the support parts on the two doors are at the same height, the two adjacent doors can be adjusted with the same height of the top wall of the cabinet as a reference surface. When the door closes the refrigeration compartment, the bottom walls of the support parts of the two adjustment seats support the top wall of the cabinet. In this way, no matter if the height difference between the two doors is caused by errors in the production process or deformation in the use process, the two adjustment seats can accurately adjust the two doors to a suitable height, so that their heights are consistent in the left and right directions. When the door closes the refrigeration compartment, the two doors can maintain the same height, avoiding new height difference problems caused by asynchronous adjustment, and further improving the accuracy and effectiveness of adjustment.

[0033] The refrigeration device in the embodiments of this utility model can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of this utility model.

[0034] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0035] like Figure 1 As shown, the refrigeration device provided in this embodiment of the present invention may include a housing 1, which forms the outer shell of the refrigeration device. The housing 1 may adopt a hollow structure such as a cuboid. It should be noted that the housing 1 may also adopt a hollow shell structure of other shapes.

[0036] Figure 2 for Figure 1 A partial schematic diagram of the middle door when it is open.

[0037] like Figure 2 As shown, in some embodiments, the interior of the housing 1 is provided with a refrigeration chamber 101, which may have a front opening.

[0038] In some embodiments, the cabinet 1 may be provided with multiple refrigeration compartments 101, which can serve as independent storage spaces, such as freezers, refrigerators, and variable temperature compartments, to meet different refrigeration needs such as freezing, refrigeration, and variable temperature according to different types of food, and to store items that need to be refrigerated or frozen. The multiple refrigeration compartments 101 can be arranged vertically or horizontally.

[0039] In some embodiments, the refrigeration device may include a liner (not shown in the figure). The liner may be disposed inside the housing 1. The liner may contain a refrigeration compartment 101.

[0040] In some embodiments, the refrigerator may include a refrigeration system (not shown). The refrigeration system may be located inside the refrigerator body 1. The refrigeration system can be used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each of the refrigeration compartments 101.

[0041] As shown in the figure, in some embodiments, the refrigeration system may include a compressor (not shown). The compressor can act as the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor can then deliver the high-temperature, high-pressure refrigerant to the condenser.

[0042] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser can be used to receive refrigerant flowing from the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thus lowering the temperature of the refrigerant.

[0043] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0044] In some embodiments, the refrigeration system may include an evaporator (not shown). A throttling device may deliver a throttled and depressurized refrigerant into the evaporator. The evaporator may be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0045] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0046] Figure 3 for Figure 1 Another schematic diagram of the middle door opening.

[0047] like Figure 3 As shown, in some embodiments, the refrigeration device includes a door 2, one side of which can be hinged to the housing 1, and can be rotated to open or close the refrigeration compartment 101. The door 2 can be located on the front side of the housing 1, and can cover the front opening of the refrigeration compartment 101 for opening and closing the refrigeration compartment 101.

[0048] like Figure 3 As shown, in some embodiments, the refrigeration device may include a hinge assembly 21, through which the door 2 is hinged to the housing 1.

[0049] The hinge assembly 21 can be provided in two sets, and the two sets of hinge assemblies 21 can be respectively provided at the upper and lower ends of the door body 2. The adjustment seat 3 can be provided at the end of the door body 2 away from the hinge assembly, that is, the end of the adjustment seat 3 near the free end of the door body 2.

[0050] like Figure 3As shown, in some embodiments, the refrigeration device includes an adjustment seat 3, which can be disposed on the door body 2 and is used to adjust the inconsistent height of the door body 2 in the left and right directions.

[0051] like Figure 3 As shown, in some embodiments, the adjusting seat 3 includes a connecting part 31, which can be provided on the side wall of the door 2 facing the refrigeration chamber 101, that is, the connecting part 31 is provided on the inner side of the door 2, which can effectively reduce the impact of the adjusting seat 3 on the appearance of the door 2.

[0052] In the width direction of the door body 2, the adjusting seat 3 is arranged at intervals with the hinge of the door body 2. Among them, the connecting part 31 is arranged at intervals with the hinge of the door body 2, that is, the connecting part 31 is located at the free end of the door body 2.

[0053] The adjustment seat 3 includes a support portion 32, one end of which is connected to the connecting portion 31 and protrudes from the connecting portion 31. The other end of the support portion 32 extends toward the side closer to the cabinet 1. When the door 2 closes the refrigeration compartment 101, the bottom wall of the support portion 32 is supported on the top wall of the cabinet 1.

[0054] Specifically, since the hinge side of the door 2 is the pivot point, the free side of the door 2 is prone to sinking. By setting the connecting part 31 at intervals between the hinge point of the door 2 and the cabinet 1 in the width direction of the door 2, and setting the adjusting seat 3 close to the free side of the door 2, the adjusting torque of the support part 32 can be improved. When the door 2 is closed on the front side of the refrigeration compartment 101, the bottom wall of the support part 32 is supported on the top wall of the cabinet 1. At this time, the support part 32 can achieve a larger height correction with a smaller supporting force and has better structural strength.

[0055] If the door 2 sinks on the side furthest from its hinge with the cabinet 1, for example, if the left side of the door 2 is hinged to the cabinet 1 and the right side of the door 2 sinks, an adjusting seat 3 can be provided on the door 2. When the door 2 is closed in front of the refrigeration compartment 101, the bottom wall of the supporting part 32 can be supported on the top wall of the cabinet 1. The reaction force of the top wall of the cabinet 1 can also lift the right side of the door 2 upwards, so that the sinking door 2 can be supported on the cabinet 1 by the adjusting seat 3, thereby offsetting the sinking on the right side and making the height of the left and right sides of the door 2 more consistent. This can simply and effectively solve the problem of inconsistent height between the left and right sides of the door 2, and avoid the inconsistency between the left and right sides of the door 2 affecting the normal closing of the door 2 and the appearance of the door 2.

[0056] Currently, due to insufficient precision and assembly errors in the hinge assembly 21 during actual production, or the door body 2 easily deforming during use, inconsistent heights in the left and right directions occur, significantly affecting the aesthetics of the refrigerator. Related technologies mainly address this by adjusting the hinge dimensions or improving the pre-assembly precision of the foamed casing 1 to achieve consistent heights in the left and right directions. However, existing adjustment methods are complex, require sophisticated modification processes, and are costly.

[0057] This application provides an adjustment seat 3 on the side wall of the door 2 facing the refrigeration compartment 101. The adjustment seat 3 includes a connecting part 31 and a supporting part 32. The connecting part 31 is connected to the inside of the door 2 and positions the supporting part 32, ensuring that the supporting part 32 is always precisely aligned with the top wall of the cabinet 1. One end of the supporting part 32 is connected to the connecting part 31, and the other end extends towards the cabinet 1. Since the end of the door 2 away from the hinge point with the cabinet 1 is prone to sinking, the supporting part 32 ensures that the door 2 is supported by the top wall of the cabinet 1 when the refrigeration compartment 101 is closed. In this way, the side of the door 2 away from the hinge point can be lifted upward by the reaction force of the top wall of the cabinet 1, thereby offsetting the sinking on the right side and making the height of the left and right sides of the door 2 more consistent. Compared to existing technologies that require adjusting or replacing the hinge structure, this application only requires installing an adjusting seat 3 on the inside of the door body 2. The adjusting seat 3 can compensate for the precision deviation of the hinge structure of the door body 2, and correct the height of the left and right sides of the door body 2 through the support part 32. This solves the problem of increased cost and structural complexity caused by repeated hinge adjustments and the installation of high-precision hinges before leaving the factory. At the same time, because the adjusting seat 3 has a simple structure and fewer parts, it greatly reduces manufacturing costs compared to high-precision hinges. Furthermore, the length of the support part 32 and the size of the connecting part 31 can be flexibly adjusted according to different door body 2 sizes, making it highly versatile and eliminating the need for separate design for different models of refrigeration units, further controlling production costs.

[0058] In some embodiments, the connecting part 31 can be tightly connected to the door body 2 by means of screws, adhesives, etc., so as to avoid displacement caused by collision during use, so that the support part 32 can always correspond to the top wall of the box body 1, and the support will not fail due to the loosening of the adjusting seat 3, thus ensuring the stability of the height correction effect.

[0059] In some embodiments, the adjustment seat 3 can be an integral injection molded or metal stamped structure.

[0060] Figure 4 for Figure 3 A three-dimensional schematic diagram of the center adjustment seat.

[0061] like Figure 4As shown, in some embodiments, the connecting part 31 can be configured as a plate-like structure, and the supporting part 32 can be configured as a plate-like structure. One side of the connecting part 31 can be attached to the side wall of the door 2 facing the refrigeration compartment 101. One end of the plate-like structure of the supporting part 32 is connected to the other side of the connecting part 31. When the door 2 is closed in front of the refrigeration compartment 101, the other end of the supporting part 32 is supported on the top wall of the housing 1, and at least one side of the supporting part 32 is at least partially attached to the top wall of the housing 1.

[0062] Figure 5 for Figure 3 Another three-dimensional diagram of the center adjustment seat; Figure 6 for Figure 5 A side view diagram.

[0063] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the end of the support portion 32 away from the connecting portion 31 is provided with a guide wall 33. The lower end of the guide wall 33 is connected to the bottom wall of the support portion 32, and the upper end of the guide wall 33 is connected to the top wall of the support portion 32. In the direction from bottom to top, the guide wall 33 extends upward at an angle toward the side closer to the housing 1.

[0064] During the closing process, the door 2 is prone to misalignment and collision with the top wall of the cabinet 1 due to issues such as deviation in the rotation angle of the door 2 or uneven closing force by the user, resulting in a jamming problem. In this embodiment, a guide wall 33 is provided at the end of the support part 32 away from the connecting part 31. The guide wall 33 is inclined from bottom to top towards the cabinet 1. When the door 2 closes to the top wall of the cabinet 1, the front end of the guide wall 33 will first contact the top wall of the cabinet 1. The inclined guide wall 33 will form a guiding slope. Even if there is a slight deviation between the initial movement direction of the support part 32 and the top wall of the cabinet 1, the inclined guide wall 33 can gradually guide the door 2 to move upward. Furthermore, the reaction force generated by the contact between the guide wall 33 and the top wall of the cabinet 1 can effectively adjust the position of the support part 32, thereby allowing the bottom wall of the support part 32 to completely fit with the top wall of the cabinet 1. This not only makes the closing process smoother and eliminates abrupt jamming, but also effectively reduces the risk of the support part 32 getting stuck at the edge of the cabinet 1 due to misalignment.

[0065] like Figure 6 As shown, in some embodiments, the guide wall 33 can be configured as an arc surface. During the closing process of the door 2, because the guide wall 33 is configured as an arc surface, the trajectory of the guide wall 33 contacting the top wall of the housing 1 to drive the adjusting seat 3 to guide the door 2 upward is a smooth curve. This process involves less resistance, making the closing action smoother and improving the user's door-closing experience.

[0066] like Figure 3As shown, in some embodiments, the adjustment seat 3 is located on the side of the door 2 away from the hinged connection with the box 1.

[0067] Specifically, with the hinge side as the pivot point, the free side of door 2, away from the hinge side, is more prone to sagging under gravity. By placing the adjusting seat 3 near the side of door 2 away from the hinge with the cabinet 1, when door 2 closes the refrigeration compartment 101, the support part 32 supports the top wall of cabinet 1, directly supporting the sagging free side of door 2. Furthermore, when door 2 is closed, its weight and the external force it experiences are transmitted to cabinet 1 through hinge assembly 21 and adjusting seat 3. By placing the adjusting seat 3 on the side of door 2 away from the hinge, the adjusting seat 3 provides additional support to door 2 on this side, increasing its stability in that direction and distributing the force on door 2 more evenly to cabinet 1. This avoids excessive local stress on door 2 or cabinet 1 due to concentrated force, thereby reducing the risk of deformation and damage to door 2 and cabinet 1, and extending the service life of the refrigeration unit.

[0068] Figure 7 for Figure 3 Exploded view of the local structure; Figure 8 for Figure 7 A magnified view of part A.

[0069] like Figure 7 and Figure 8 As shown, in some embodiments, the side wall of the door 2 facing the refrigeration compartment 101 is provided with a positioning groove 201. The positioning groove 201 can be formed by a recess in the side wall of the door 2, and the positioning groove 201 can be provided on the side of the door 2 away from the hinge with the cabinet 1. The connecting part 31 is embedded in the positioning groove 201 to fix it on the door 2.

[0070] In this design, by setting a positioning groove 201 on the side wall of the door 2 facing the refrigeration chamber 101, the positioning groove 201 can provide precise positioning for the installation of the adjusting seat 3 on the door 2. During the installation process, the connecting part 31 can be accurately embedded into the positioning groove 201, avoiding the adjustment seat 3 from shifting in the left or right or up or down direction on the door 2, ensuring that the relative position of the adjusting seat 3 and the door 2 is fixed, thereby improving the stability of the adjusting seat 3 supporting the door 2.

[0071] Furthermore, the groove structure of the positioning groove 201 can increase the contact area or connection area with the connecting part 31. For example, the peripheral sidewall and bottom wall of the positioning groove 201 can form a wrapping limit on the connecting part 31, preventing the connecting part 31 from moving along the width direction or thickness direction of the door body 2 and detaching from the door body 2, thereby improving the installation stability and reliability of the adjusting seat 3. Further, when the connecting part 31 is embedded in the positioning groove 201, the outer sidewall of the connecting part 31 can fully fit with the inner sidewall of the positioning groove 201. A larger contact area can also distribute the weight load of the door body 2 borne by the adjusting seat 3, avoiding connection failure between the adjusting seat 3 and the door body 2 due to excessive local stress.

[0072] Furthermore, the refrigeration device may include a connector 4, which passes through and connects the adjusting seat 3 and the mounting groove, thereby further improving the connection reliability between the adjusting seat 3 and the door body 2. Multiple connectors 4 may be provided, arranged at intervals between them. For example, Figure 4 As shown, the connecting part 31 may be provided with a connecting hole 301, through which the connecting member 4 can pass, so that the other end of the connecting member 4 can fix the connecting part 31 to the door body 2.

[0073] like Figure 4 , Figure 6 and Figure 8 As shown, in some embodiments, a positioning hole 202 may be provided in the positioning groove 201, and the positioning hole 202 is connected to the positioning groove 201.

[0074] The connecting part 31 is provided with a positioning post 34 protruding on the side facing the door body 2. The positioning post 34 is provided in correspondence with the positioning hole 202 and is inserted into the positioning hole 202.

[0075] To further improve the speed and accuracy of installation of the adjusting seat 3 and the door body 2, a positioning hole 202 is provided in the positioning groove 201, and the connecting part 31 is provided with a positioning hole 202 corresponding to the positioning hole 202. When assembling the adjusting seat 3 and the door body 2, the relative position of the positioning post 34 and the positioning hole 202 can provide a guiding reference for the installation, avoiding left-right deviation or front-back misalignment of the connecting part 31 during the installation process. Moreover, during the opening and closing of the door body 2, the adjusting seat 3 may be subjected to a certain torque. If positioning is only based on the positioning groove 201, the connecting part 31 may rotate slightly within the positioning groove 201, affecting the stability and function of the adjusting seat 3. The positioning post 34, inserted into the positioning hole 202, can effectively limit the rotation of the connecting part 31 in the horizontal plane, making the connection between the adjusting seat 3 and the door body 2 more stable.

[0076] On the other hand, the door body 2 and the adjusting seat 3 are connected by the corresponding arrangement of the positioning post 34 and the positioning hole 202. After the connecting part 31 is embedded in the positioning groove 201, the insertion connection of the positioning post 34 and the positioning hole 202 can increase the connection point and connection area between the connecting part 31 and the door body 2. The matching arrangement of the positioning post 34 and the positioning hole 202 can further disperse the stress when the adjusting seat 3 is supported on the top surface of the box body 1, and improve the support structure strength of the adjusting seat 3.

[0077] It should be noted that in some other embodiments, a positioning post 34 may be protruding in the positioning groove 201, and a positioning hole 202 may be recessed on the side of the connecting part 31 facing the door body 2. The positioning post 34 is correspondingly arranged with the positioning hole 202, and the positioning post 34 is inserted into the positioning hole 202.

[0078] Figure 9 for Figure 1 A cross-sectional view.

[0079] like Figure 6 and Figure 9 As shown, in some embodiments, the adjusting seat 3 may include a first reinforcing rib 35. The first reinforcing rib 35 may be integrally formed with the connecting portion 31 and the supporting portion 32.

[0080] The first reinforcing rib 35 is located at the bottom of the support portion 32. The first reinforcing rib 35 connects the connecting portion 31 and the bottom wall of the support portion 32. The side of the first reinforcing rib 35 closest to the door body 2 is connected to the connecting portion 31, and the top edge of the first reinforcing rib 35 is connected to the bottom wall of the support portion 32. The first reinforcing rib 35 can be connected to the connecting portion 31 via its side edge closest to the door body 2, and to the support portion 32 via its top side edge, thereby increasing the connection area and improving the connection strength.

[0081] Specifically, when the door 2 closes the refrigeration compartment 101, the upward reaction force borne by the bottom wall of the support part 32 is transmitted to the connection part 31 along the support part 32 itself by connecting the first reinforcing rib 35 to the bottom wall of the connection part 31. The other part of the force can be directly transmitted to the connection part 31 through the first reinforcing rib 35, thereby preventing the support part 32 from breaking or being damaged due to stress concentration.

[0082] On the other hand, the bottom wall of the support part 32 is the contact surface with the top wall of the box 1. By connecting the first reinforcing rib 35 to the bottom wall of the support part 32, the structural strength of the support part 32 can be further optimized and the bending rigidity of the bottom wall of the support part 32 can be enhanced. This is beneficial for the bottom wall of the support part 32 to fit tightly with the top wall of the box 1 when the door 2 is closed, so as to avoid insufficient support due to the deformation of the bottom wall and affect the height correction effect of the door 2.

[0083] like Figure 5 As shown, in some embodiments, at least two first reinforcing ribs 35 may be provided, and the two first reinforcing ribs 35 may be arranged at intervals on the bottom wall of the support 32 to further improve the overall structural strength of the adjustment seat 3.

[0084] like Figure 9 As shown, in some embodiments, a door seal 22 may be provided on the side wall of the door 2 facing the refrigeration compartment 101. The door seal 22 is disposed around the periphery of the door 2. When the door 2 closes the refrigeration compartment 101, the door seal 22 is clamped between the door 2 and the front side wall of the cabinet 1, and the first reinforcing rib 35 is located between the outer periphery of the door seal 22 and the front side wall of the cabinet 1.

[0085] Specifically, the door seal 22 can be a ring-shaped structure. The side of the door 2 facing the refrigeration chamber 101 is the door liner. The ring-shaped door seal 22 is set around the periphery of the door liner. When the door 2 closes the refrigeration chamber 101, the door seal 22 can be set around the front opening of the refrigeration chamber 101, thereby sealing the gaps formed between the door 2 and the cabinet 1 at various positions and improving the heat preservation effect of the refrigeration chamber 101.

[0086] The main function of the adjusting seat 3 is to support the door 2 through the support part 32 to adjust its height, ensuring that the left and right heights of the door 2 are consistent. In this embodiment, by setting the first reinforcing rib 35 between the outer periphery of the door seal 22 and the front side wall of the housing 1, interference between the first reinforcing rib 35 and the door seal 22 during the opening and closing process can be avoided. When the door 2 is closed, the support part 32 can smoothly contact the top wall of the housing 1 and achieve stable support, which is conducive to the adjusting seat 3 being able to play its role in adjusting the height of the door 2 normally, and its functional stability will not be affected by the interference of the door seal 22.

[0087] On the other hand, the first reinforcing rib 35 is located between the outer periphery of the door seal 22 and the front side wall of the cabinet 1. From the appearance, it will not be directly exposed to the user's view, making the overall appearance of the refrigeration unit neater and more beautiful.

[0088] like Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the adjusting seat 3 may include a second reinforcing rib 36, which is disposed on the top of the support portion 32. The second reinforcing rib 36 may be symmetrically arranged with the first reinforcing rib 35 on the upper and lower sides of the support portion 32.

[0089] The second reinforcing rib 36 is connected between the connecting part 31 and the top wall of the supporting part 32. The side of the second reinforcing rib 36 closest to the door body 2 is connected to the connecting part 31, and the bottom end of the second reinforcing rib 36 is connected to the top wall of the supporting part 32. The second reinforcing rib 36 can be connected to the connecting part 31 through the side edge closest to the door body 2, and to the supporting part 32 through the side edge of its bottom end, thereby increasing the connection area and improving the connection strength.

[0090] Specifically, by connecting the second reinforcing rib 36 to the bottom wall of the connecting part 31 and the supporting part 32, when the door 2 closes the refrigeration compartment 101, the supporting part 32 rests on the top wall of the cabinet 1, and its bottom wall bears an upward reaction force. At this time, the second reinforcing rib 36 located at the top of the supporting part 32 can bear the tensile stress. Specifically, when the supporting part 32 is subjected to force and bends outward towards the cabinet 1, the tensile force generated at the top of the supporting part 32 can be transmitted to the connecting part 31 through the second reinforcing rib 36. At the same time, in conjunction with the first reinforcing rib 35 at the bottom to share the stress, the stress on the first reinforcing rib 35 when it is supported at the top of the cabinet 1 can be effectively reduced, and the risk of damage to the supporting part 32 due to tension at the top can be reduced.

[0091] On the other hand, as a structure that directly contacts the top wall of the housing 1, the support part 32 can effectively strengthen the structural strength of the support part 32 by connecting the first reinforcing rib 35 to the bottom wall of the support part 32 and the second reinforcing rib 36 to the top wall of the support part 32. This enhances the overall bending rigidity of the support part 32 and ensures that the bottom wall of the support part 32 can fit tightly against the top wall of the housing 1 when the door 2 is closed. This avoids insufficient support due to deformation of the bottom wall of the support part 32, which would affect the height correction effect of the door 2.

[0092] like Figure 5 and Figure 6 As shown, in some embodiments, at least two second reinforcing ribs 36 may be provided, and the two second reinforcing ribs 36 may be arranged at intervals on the top wall of the support 32 to further improve the overall structural strength of the adjustment seat 3.

[0093] Furthermore, the second reinforcing ribs 36 and the first reinforcing ribs 35 respectively located on the upper and lower sides of the support part 32 can be arranged in a one-to-one correspondence, or the second reinforcing ribs 36 and the first reinforcing ribs 35 respectively located on the upper and lower sides of the support part 32 can be arranged in a staggered manner.

[0094] like Figure 9 As shown, in some embodiments, when the door 2 closes the refrigeration compartment 101, the first reinforcing rib 35 can be arranged at a distance from the front wall of the box 1, and the end of the second reinforcing rib 36 away from the connecting part 31 can be extended and arranged above the support area of ​​the support part 32 and the top wall of the box 1.

[0095] During the closing process of the door 2, the first reinforcing rib 35 moves closer to the housing 1 along with the support 32. By arranging the first reinforcing rib 35 at intervals on the front side of the front wall of the housing 1, interference and collision between the ends of the first reinforcing rib 35 and the housing 1 are effectively avoided, reducing the risk of wear and tear on the first reinforcing rib 35 and the adjustment seat 3 as a whole. On the other hand, the interval arrangement of the first reinforcing rib 35 and the front wall of the housing 1 can accommodate manufacturing errors of the adjustment seat 3 and the housing 1. Even if there are local unevennesses on the front wall of the housing 1, the first reinforcing rib 35 will not be directly squeezed, allowing the first reinforcing rib 35 to stably transmit the stress from the support 32.

[0096] Furthermore, since the bottom wall of the support part 32 contacts the top wall of the box 1 and is supported on the top of the box 1, the contact support area between the two needs to bear concentrated stress. By extending the end of the second reinforcing rib 36 away from the connecting part 31 above the support area of ​​the support part 32 and the top wall of the box 1, the second reinforcing rib 36 can directly bear part of the stress of the support part 32. Moreover, at the moment of closing the door, even if the adjusting seat 3 is subjected to instantaneous impact, the cooperative arrangement of the first reinforcing rib 35 and the second reinforcing rib 36 can effectively reduce the risk of local bending of the support part 32.

[0097] In some embodiments, a bent connecting wall 11 may be provided at the connection between the front wall and the top wall of the housing 1, and the first reinforcing rib 35 near the end of the housing 1 may be arranged at intervals above the bent connecting wall 11. The bent connecting wall 11 may be arc-shaped, which can provide sufficient clearance for the first reinforcing rib 35 and improve the stability of the fit between the housing 1 and the adjusting seat 3. Figure 10 for Figure 1 The top diagram.

[0098] like Figure 10 As shown, in some embodiments, there may be two doors 2, which are arranged side by side, with one door 2 hinged to one side of the box 1 and the other door 2 hinged to the other side of the box 1.

[0099] There are two adjustment seats 3. Each of the two door bodies 2 has an adjustment seat 3. The adjustment seats 3 are arranged on the side of the door body 2 away from the hinge with the box body 1, and the bottom wall of the support part 32 of the two adjustment seats 3 is located at the same height of the box body 1.

[0100] Currently, some multi-door refrigerators, such as double-door refrigerators and French door refrigerators, have inconsistent heights on both sides of the door 2 due to differences in hinge precision, assembly errors, or even the weight of the door 2. This can lead to uneven heights and affect the product's appearance over time.

[0101] By placing two adjustment seats 3 on the sides of the left and right doors 2 away from the hinges, and ensuring that the bottom walls of the support parts 32 on both doors 2 are at the same height, the two adjacent doors 2 can be adjusted using the same height of the top wall of the cabinet 1 as a reference surface. When the door 2 closes the refrigeration chamber 101, the bottom walls of the support parts 32 of the two adjustment seats 3 are supported by the top wall of the cabinet 1. In this way, regardless of whether the height difference between the two doors 2 is caused by errors in the production process or deformation during use, the two adjustment seats 3 can accurately adjust the two doors 2 to a suitable height, making them consistent in the left and right directions. When the door 2 closes the refrigeration chamber 101, the two doors 2 can maintain a level height, avoiding new height differences caused by asynchronous adjustments, and further improving the accuracy and effectiveness of the adjustment.

[0102] For double-door and multi-door refrigerators, this embodiment eliminates the need to modify hinge dimensions or adjust the pre-installation precision of the foam casing 1 to solve the problem of inconsistent door heights 2. Simply installing an adjustment seat 3 on each of the two doors 2 results in a simple structure and convenient installation. During refrigerator use, if inconsistent door heights occur, no complex operations by professional technicians are required. Users can easily adjust the door heights using the adjustment seats 3, saving on repair and time costs.

[0103] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
