A layered structure for a refrigerator

Abstract

This utility model discloses a layered structure for a refrigerator, including a refrigerator body, a refrigeration cavity, a central beam, an upper door, a lower door, and partitions. This design replaces the traditional foamed partition with a detachable partition. During installation, the partition is simply inserted from the top of the refrigeration cavity, with the connector on the rear side of the partition inserted into the limiting slot at the rear end of the refrigeration cavity. Then, the entire partition is installed downwards, with its left and right sides supported by the receiving platforms on the left and right sides of the refrigeration cavity, and its front end supported by the supporting surface at the rear end of the central beam. Simultaneously, the hooks at the bottom of the partition engage with the locking positions below the receiving platforms and / or the supporting surfaces, thus securing the partition. For larger items, the partition can be removed to increase the volume. The manufacturing process is simpler, and since foaming technology is not used to consume excessive space, the refrigerator has a larger usable volume for the same size.

Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a layered structure for a refrigerator. Background Technology

[0002] In Japanese refrigerators, in addition to the refrigerator and freezer compartments, a separate vegetable compartment is typically placed between them. All three compartments are controlled by independent doors. During production, the refrigerator and vegetable compartments are usually stamped together as a single cavity, and then a central beam and foam partition are placed between them. This structure is also currently used in three-door refrigerators with a fruit and vegetable compartment in China. However, this method has a drawback: the foam partition separating the refrigerator and vegetable compartments is relatively thick and requires a foaming process, which reduces the overall usable volume of the refrigerator and makes manufacturing more complex. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a layered structure for a refrigerator that is easy to install and does not significantly reduce the usable volume.

[0004] The technical solution adopted by this utility model to solve the problem is: a layered structure for a refrigerator, comprising:

[0005] The refrigerator body has a refrigeration chamber with a front opening. A central beam is horizontally arranged at the front opening of the refrigeration chamber. At least one limiting slot flush with the central beam is arranged on the inner end face of the refrigeration chamber in the horizontal direction. A receiving platform is arranged on both side walls of the refrigeration chamber. A support surface is arranged at the rear end of the central beam. A locking position is arranged below the receiving platform and / or support surface.

[0006] The upper door body is pivotally connected to the upper part of the front opening of the refrigerator body for covering the refrigeration cavity. When the upper door body covers the refrigeration cavity, the bottom of the inner side of the upper door body is attached to the upper part of the outer end face of the middle beam.

[0007] The lower door is pivotally connected to the lower part of the front opening of the refrigerator body for covering the refrigeration cavity. When the lower door covers the refrigeration cavity, the top of the inner side of the lower door is attached to the lower part of the outer end face of the middle beam.

[0008] A partition, wherein the rear side of the partition is provided with a plug extending toward the rear end, and the bottom sides and / or the bottom front end of the partition are provided with elastic hooks extending downward and toward the outside.

[0009] The partition can be detachably installed into the refrigeration chamber to divide the refrigeration chamber into an upper cooling chamber and a lower cooling chamber. When the partition is installed into the refrigeration chamber, the rear end face of the partition is attached to the rear end face of the refrigeration chamber and the plug is inserted into the limiting slot. The two sides of the partition are supported by the receiving platform, the front side of the partition is supported by the supporting surface, and the hook is engaged with the locking position.

[0010] As a further improvement to the above technical solution, two limiting slots are provided, which are symmetrically arranged on the inner end face of the refrigeration chamber.

[0011] As a further improvement to the above technical solution, an air duct plate arranged along the height direction is provided in the middle of the inner end face of the refrigeration chamber, and two limiting slots are respectively arranged on both sides of the air duct plate. When the partition is installed into the refrigeration chamber, the rear end face of the partition also abuts against the surface of the air duct plate.

[0012] As a further improvement to the above technical solution, the middle part of the rear end face of the central beam protrudes towards the rear to form a horizontally arranged mounting strip, and the lower end face of the mounting strip forms the locking position.

[0013] As a further improvement to the above technical solution, the surface of the mounting strip is provided with a guide slope for guiding the elastic hook to undergo elastic deformation and slide into the locking position.

[0014] As a further improvement to the above technical solution, the upper end face of the mounting strip is provided with several upwardly extending pins, the front end of the partition is provided with a front flange, the bottom of the front flange is provided with a positioning hole for the pins to be inserted, and the front flange is supported by the supporting surface.

[0015] As a further improvement to the above technical solution, the top of the partition forms a drawer.

[0016] As a further improvement to the above technical solution, the rear end face of the accommodating drawer is provided with a ventilation hole that communicates with the lower cooling cavity.

[0017] As a further improvement to the above technical solution, the receiving platform includes a large platform at the rear end, a small platform connected to the front end of the large platform, a positioning platform connected to the front end of the small platform, and a spacer platform located at the front end of the positioning platform. The bottoms of the large platform and the small platform are flush, the top of the large platform is higher than the top of the small platform, the tops of the small platform, the positioning platform, and the spacer platform are flush, and the bottom of the positioning platform is higher than the bottom of the small platform. The bottom of the positioning platform forms the positioning position, and a spacer space is formed between the spacer platform and the positioning platform. The rear ends of both sides of the partition are provided with an inwardly recessed stepped cavity. The tops of the small platform, the positioning platform, and the spacer platform are mutually supported by the bottom of the side of the partition. The large platform is located in the stepped cavity to support the top surface of the stepped cavity.

[0018] As a further improvement to the above technical solution, the partition is provided with side flanges on both sides for fitting against the side walls of the refrigeration chamber.

[0019] The beneficial effects of this utility model are as follows: By replacing the traditional foamed partition with a detachable partition, installation is simple. The partition is inserted from the top of the refrigeration chamber, and the connector on the back of the partition is inserted into the limiting slot at the rear end of the refrigeration chamber. Then, the entire partition is installed downwards, so that its left and right sides are supported by the receiving platforms on the left and right sides of the refrigeration chamber, and its front end is supported by the support surface at the rear end of the central beam. Simultaneously, the hooks at the bottom of the partition engage with the locking positions below the receiving platforms and / or support surfaces, thus securing the partition. Because the rear end of the partition is in contact with the rear end surface of the refrigeration chamber, its left and right sides are supported by the receiving platforms, and its front end is supported by the support surface, the sealing between the upper and lower cold chambers of the refrigeration chamber is ensured. Furthermore, if larger items need to be placed, the partition can be removed, connecting the lower and upper cold chambers into one unit, thereby enhancing the refrigerator's practicality. Compared to existing technologies, the production process is simpler, and it does not use foaming technology to take up too much space, resulting in a larger usable volume for the same size refrigerator.

[0031] Reference Figures 1 to 6 A layered structure for a refrigerator, comprising:

[0032] The refrigerator body 10 has a refrigeration cavity 11 with a front opening. A central beam 12 is horizontally arranged at the front opening of the refrigeration cavity 11. At least one limiting slot 113 flush with the central beam 12 is arranged on the inner end face of the refrigeration cavity 11 in the horizontal direction. A receiving platform 20 is arranged on both side walls of the refrigeration cavity 11. A support surface 121 is arranged at the rear end of the central beam 12. A locking position 30 is arranged below the receiving platform 20 and / or the support surface 121.

[0033] The upper door 40 is pivotally connected to the upper part of the front opening of the refrigerator body 10 for covering the refrigeration cavity 11. When the upper door 40 covers the refrigeration cavity 11, the bottom of the inner side of the upper door 40 is attached to the upper part of the outer end face of the middle beam 12.

[0034] The lower door 41 is pivotally connected to the lower part of the front opening of the refrigerator body 10 for covering the refrigeration cavity 11. When the lower door 41 covers the refrigeration cavity 11, the top of the inner side of the lower door 41 is attached to the lower part of the outer end face of the middle beam 12.

[0035] The partition 50 has a connector 51 extending toward the rear end on its rear side, and elastic hooks 52 extending downward and toward the outside are provided on the bottom of both sides and / or the bottom of the front end of the partition 50.

[0036] The partition 50 can be detachably installed into the refrigeration chamber 11 to divide the refrigeration chamber 11 into an upper cooling chamber 111 and a lower cooling chamber 112. The upper cooling chamber 111 is generally a refrigerator compartment, while the lower cooling chamber 112 is generally a fruit and vegetable compartment or a wild vegetable compartment. When the partition 50 is installed into the refrigeration chamber 11, the rear end face of the partition 50 is attached to the rear end face of the refrigeration chamber 11, and the connector 51 is inserted into the limiting slot 113. The two sides of the partition 50 are supported by the receiving platform 20, and the front side of the partition 50 is supported by the supporting surface 121. The hook is engaged with the locking position 30.

[0037] In this solution, the traditional foamed partition is replaced with a detachable partition 50. During installation, the partition 50 is simply inserted from the top of the refrigeration chamber 11, and the connector 51 on the rear side of the partition 50 is inserted into the limiting slot 113 at the rear end of the refrigeration chamber 11. Then, the entire partition 50 is installed downwards, so that the left and right sides of the partition 50 are supported by the receiving platforms 20 on the left and right sides of the refrigeration chamber 11, and the front end of the partition 50 is supported by the support surface 121 at the rear end of the central beam 12. At the same time, the hook at the bottom of the partition 50 engages with the locking position 30 below the receiving platform 20 and / or the support surface 121, thereby fixing the partition 50. Because the rear end of the partition 50 is fitted to the rear end face of the refrigeration cavity 11, and its left and right sides are supported by the receiving platform 20, while its front end is supported by the supporting surface 121, the sealing between the upper cold cavity 111 and the lower cold cavity 112 of the refrigeration cavity 11 can be guaranteed. Furthermore, if larger items need to be placed, the partition 50 can be removed, thereby connecting the lower cold cavity 112 and the upper cold cavity 111 into one unit, enhancing the refrigerator's practicality. Compared to existing technologies, the production process is simpler, and it does not use a foaming process that would otherwise occupy excessive space, resulting in a larger usable volume for the same size refrigerator.

[0038] To further optimize the design and ensure uniform force distribution on the partition 50, it is preferable to have two limiting slots 113, which are symmetrically arranged on the inner end face of the refrigeration chamber 11. Considering the structural arrangement of the air duct plate, it is preferable to have an air duct plate arranged along the height direction in the middle of the inner end face of the refrigeration chamber 11, with the two limiting slots 113 respectively arranged on both sides of the air duct plate. When the partition 50 is detachably installed into the refrigeration chamber 11, the rear end face of the partition 50 also abuts against the surface of the air duct plate.

[0039] In this design, preferably, the rear end face of the middle beam 12 protrudes towards the rear to form a horizontally arranged mounting strip 122, and the lower end face of the mounting strip 122 forms the locking position 30. Furthermore, to facilitate the engagement of the locking hook with the locking position 30, preferably, the surface of the mounting strip 122 is provided with a guide slope 124 for guiding the elastic locking hook 52 to undergo elastic deformation and slide towards the locking position 30.

[0040] To further ensure the accuracy of the partition 50's position and prevent deformation during use, preferably, the upper surface of the mounting strip 122 is provided with several upwardly extending pins 123, and the front end of the partition 50 is provided with a front flange 54. The bottom of the front flange 54 is provided with a positioning hole 53 for the pins 123 to be inserted into, and the front flange 54 is supported by the support surface 121. By cooperating with the pins 123 through the positioning hole 53 at the bottom of the front flange 54, the partition 50 is tightened from the front end, preventing deformation of the front end of the partition 50.

[0041] To further optimize the functionality of the partition 50, it is preferable that the top of the partition 50 forms a drawer. Also, considering that in some refrigerators, the vegetable compartment and the refrigerator compartment may be connected to facilitate cold air circulation, it is preferable that the rear end face of the drawer has a ventilation hole that communicates with the lower cold compartment 112.

[0042] Further optimization: In this solution, the receiving platform 20 preferably includes a large platform 21 at the rear end, a small platform 22 connected to the front end of the large platform 21, a positioning platform 23 connected to the front end of the small platform 22, and a spacer platform 24 located at the front end of the positioning platform 23. The bottoms of the large platform 21 and the small platform 22 are flush, the top of the large platform 21 is higher than the top of the small platform 22, the tops of the small platform 22, the positioning platform 23, and the spacer platform 24 are flush, and the bottom of the positioning platform 23 is higher than the bottom of the small platform 22. The bottom of the positioning platform 23 forms the positioning 30, and a spacer space 25 is formed between the spacer platform 24 and the positioning platform 23.

[0043] The rear ends of both sides of the partition 50 are provided with an inwardly recessed stepped cavity 55. The tops of the small platform 22, the positioning platform 23 and the spacer platform 24 are connected to the bottom of the side of the partition 50. The large platform 21 is located in the stepped cavity 55 and is used to support the top surface of the stepped cavity 20.

[0044] However, in other embodiments, the receiving platform 20 may also be a complete strip structure extending from the rear end to the front end of the refrigeration chamber 11.

[0045] To further ensure the sealing between the side of the partition 50 and the two side walls of the refrigeration chamber 11, it is preferable that the two sides of the partition 50 are provided with side flanges 56 for fitting against the two side walls of the refrigeration chamber 11.

[0046] In order to ensure airtightness, additional sealing strips can be added to the gap between the partition 50 and the inner wall of the refrigeration chamber 11 to supplement the sealing effect.

[0047] Although this solution is explained in the specific implementation as a layered structure of a cold storage room and a wild vegetable room or a fruit and vegetable room, in actual use it can also be used as a layered structure of a cold storage room and a freezer room.

[0048] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
