Description

Technical Field

[0001] This utility model relates to the field of home appliances, and in particular to a food preservation drawer and a refrigeration device. Background Technology

[0002] With the fast pace of life and the improvement of living standards, people are placing increasingly higher demands on the durability and freshness of food preservation.

[0003] Generally, refrigerators extend the shelf life of food by regulating temperature and humidity. However, simply adjusting temperature and humidity cannot "shut down" food, especially fresh fruit; it only slows down its metabolism, falling far short of people's requirements for food freshness and durability. We know that replacing the air in the food storage environment with inert gases like nitrogen can achieve the same effect as "shutting down" fresh fruit, while increasing the oxygen content can keep live animals like shrimp and fish alive, significantly extending their shelf life.

[0004] Currently, the fresh food storage compartment uses sealed buckets in conjunction with drawers. However, the area that actually needs to be deoxygenated or enriched with oxygen is only inside the drawer. The space between the drawer and the bucket is inherently detrimental to the deoxygenation efficiency. At the same time, the cost of the bucket is relatively high, which is not conducive to mass production. Moreover, because of the obstruction of the bucket, it is not conducive to the cooling of the drawer, which also affects energy saving. Summary of the Invention

[0028] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0029] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Please see Figure 1-4 , Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of the present invention; Figure 2This is a schematic diagram of a food preservation drawer according to an embodiment of the present invention; Figure 3 This is an exploded view of a food storage drawer according to an embodiment of the present invention; Figure 4 This is an exploded view of a food storage drawer according to another embodiment of the present invention. The present invention provides a refrigeration device, which includes a cabinet 100 and a food storage drawer 200 as described in any of the following embodiments. The cabinet has an inner liner 300 that encloses multiple storage spaces, and the food storage drawer 200 is disposed within the storage spaces enclosed by the inner liner 300. The refrigeration device cools the storage spaces using refrigeration equipment (such as a compressor, evaporator, and condenser). The refrigeration device can be a refrigerator, freezer, etc. The cabinet 100 can have multiple storage spaces, such as a refrigerator compartment, a variable temperature compartment, and a freezer compartment. Preferably, the food storage drawer 200 is disposed in the refrigerator compartment or the variable temperature compartment.

[0031] The preservation drawer 200 includes not only the drawer assembly 10 but also an air supply mechanism 20. The air supply mechanism 20 provides preservation gas to the storage compartment. This preservation gas can be nitrogen, used to sedate fresh fruits, or oxygen, used to keep live animals such as shrimp and fish alive; users can choose according to their needs. Furthermore, the air supply mechanism 20 includes a fan assembly and a controlled atmosphere module. The fan assembly delivers the preservation gas provided by the controlled atmosphere module to the storage compartment and causes the air in the storage compartment to be expelled through the controlled atmosphere module.

[0032] Generally, the modified atmosphere module includes an electrolytic modified atmosphere unit and a modified atmosphere channel. The electrolytic modified atmosphere unit can be configured to generate a preservative gas through electrochemical reactions, filtration, or adsorption, and then deliver this gas to the refrigeration drawer via the modified atmosphere channel. Furthermore, the preservative gas flowing through the modified atmosphere channel can be selected according to actual needs.

[0033] Furthermore, the refrigeration device of this embodiment has all the beneficial effects of the preservation drawer as described in any of the following embodiments, which will not be repeated here.

[0034] Please continue reading Figure 1 - Figure 4 Please also see Figure 5 - Figure 9 , Figure 5 This is a schematic diagram of the drawer body according to an embodiment of the present utility model; Figure 6 This is a schematic diagram of a drawer lid according to an embodiment of the present invention;

[0035] Figure 7 This is a schematic diagram of the drawer lid from another angle, representing one embodiment of the present invention. Figure 8This is a schematic diagram of the drawer lid and drawer body in a first state according to an embodiment of the present invention; Figure 9 This is a schematic diagram of the drawer lid and drawer body in a second state according to an embodiment of the present invention. The present invention also provides a food preservation drawer 200, which includes a drawer assembly 10 and an air supply mechanism 20. The drawer assembly 10 includes a drawer body 30, a drawer lid 40, and a box body 50. The drawer body 30 and the box body 50 are connected by sliding along the longitudinal direction of the drawer body 30 (i.e., the front-to-back direction of the drawer body 30). The top 31 of the drawer body 30 has a top opening 32. The outer surfaces of the two transverse side walls 33 and 34 of the drawer body 30 (i.e., the two side walls 33 and 34 extending along the longitudinal direction of the drawer body 30) each have a first slide rail 35, which extends along the longitudinal direction of the drawer body 30. The drawer lid 40 covers the top opening 32, and a storage compartment is formed between the drawer body 30 and the drawer lid 40. The storage compartment is an openable and sealed structure. The periphery of the drawer lid 40 corresponding to the first slide rail 35 forms a groove leading to the bottom 36 of the drawer body 30 (e.g., ...). Figure 5 As shown in the diagram, a protruding support structure 41 extends outward, and each support structure 41 is provided with a first roller 42, each first roller 42 being slidably supported on a first slide rail 35 on the corresponding side. That is, during the process of pushing and pulling the drawer body 30 relative to the box body 50, the first roller 42 will roll along the first slide rail 35. The first roller 42 can be, for example, located at the end of the support structure 41 facing the bottom 36, but the invention is not limited to this. For example, it can also be located on the support structure 41 and between the periphery of the drawer cover 40 and the end of the support structure 41 facing the bottom 36, as long as it does not interfere with other components during the pushing and pulling of the drawer body 30.

[0036] The air supply mechanism 20 is located outside the drawer body 30 and connected to the storage compartment via a pipe, and the ventilation ports of the storage compartment are all located on the drawer cover 30. As described above, in this embodiment, the fan assembly and the controlled atmosphere module are, for example, located outside the drawer body 30. However, this invention is not limited to this; in another embodiment, for example, the controlled atmosphere module can also be located inside the inner liner 300 (e.g., in the refrigerator compartment), or between the inner liner 300 and the refrigerator body 100, or in the mechanical compartment; of course, these variations in location are all feasible within the technical spirit of this invention.

[0037] In one embodiment, the piping further includes a drawer air inlet channel 21 and a drawer air return channel 22. Both the drawer air inlet channel 21 and the drawer air return channel 22 are located on a first surface 43 of the drawer cover 40 away from the top opening 32. The ventilation port includes an air inlet 23 and an air return port 24. The drawer air inlet channel 21 connects the air inlet 23 to the air supply mechanism 20, and the drawer air return channel 22 connects the air return port 24 to the air supply mechanism 20. The ventilation ports of the storage compartment are all located on the drawer cover 30, meaning that both the air inlet 23 and the air return port 24 are located inside the storage compartment.

[0038] Furthermore, each first slide rail 35 has a track portion 351 and a recessed portion 352 recessed along a first direction D1, where the first direction D1 is the direction from the top 31 of the drawer body 30 to the bottom 36 of the drawer body 30. The first state in which the drawer lid 40 is sealed to the drawer body 30 corresponds to the state in which each first roller 42 is located in the corresponding recessed portion 352. The second state in which the drawer body 30 moves out of the box 50 corresponds to the state in which each first roller 42 disengages from the corresponding recessed portion 352 and is supported on the track portion 351. The drawer lid 40 has a first displacement relative to the top 31 of the drawer body 30 along a second direction D2, where the first direction D1 is opposite to the second direction D2. That is, as... Figure 8 As shown, when the drawer lid 40 is sealed to the drawer body 30, each first roller 42 is located within the corresponding recess 352; as Figure 9As shown, when the drawer body 30 moves out of the box 50, that is, when the drawer body 30 is pulled out relative to the box 50, each first roller 42 will disengage from the corresponding recess 352 and be supported on the track 351. Moreover, since the position of the recess 352 in the first direction D1 is lower than the position of the track 351, when the drawer body 30 is pulled out of the box 50, the first roller 42 will rise upward (along the second direction). As a result, the drawer cover 40 connected to the first roller 42 will be raised or lifted. That is, at this time, the drawer cover 40 has a first displacement relative to the top 31 of the drawer body 30 along the second direction D2. The drawer cover 40 can automatically rise or fall during the pushing and pulling of the drawer body 30, saving time and effort, and avoiding the friction between the drawer body 30 and the drawer cover 40 during the pushing and pulling process, which would cause operational difficulties and noise. Furthermore, as the drawer body 30 continues to be pulled out, the first roller 42 will slide on the corresponding track portion 351 of the first slide rail 35 until the drawer body 30 is pulled out to its limit. When the drawer body 30 is pushed into the box 50, the drawer body 30 will drive the first slide rail 35 to move backwards towards the box 50, and the first roller 42 will slide on the corresponding track portion 351 of the first slide rail 35 until the first roller 42 enters the recess 352 from the first opening 354 and is confined within the recess 352.

[0039] Furthermore, in this embodiment, each recess 352 has a locking mechanism 353 on the side adjacent to the top 31 of the drawer body 30. A first opening 354 is formed between each locking mechanism 353 and its corresponding recess 352. The orientation of the first opening 354 is opposite to the direction in which the drawer body 30 is pulled out of the box 50, and the minimum distance between each locking mechanism 353 and its corresponding recess 352 in the first direction D1 is equal to the diameter of the first roller 42. That is, when the drawer body 30 is pulled out of the box 50, the first roller 42 will disengage from the corresponding recess 352 through the first opening 354 and be supported on the track portion 351. Moreover, when the first roller 42 is located in the corresponding recess 352, the locking mechanism 353 will press the first roller 42 downwards, causing the drawer cover 40 to press tightly against the drawer body 30, achieving a better seal.

[0040] Furthermore, preferably, in this embodiment, each recess 352 includes an inclined portion 355 and a flat portion 356. The inclined portion 355 connects the corresponding track portion 351 and the flat portion 356. Each locking mechanism 353 includes a guide portion 357 and a stop portion 358. The inclined portion 355 is parallel to the corresponding guide portion 357, the flat portion 356 is parallel to the corresponding track portion 351, and the stop portion 358 connects the corresponding guide portion 357 and the flat portion 356. The stop portion 358 is arranged along the first direction D1. That is to say, whether the drawer body 30 is pulled out of the box 50 or pushed into the box 50, the inclined portion 355 makes the first roller 42 move in and out of the corresponding recess 352 more smoothly. In addition, the recessed portion 352 is configured to cooperate with the corresponding locking mechanism 353. When the first roller 42 enters the corresponding recessed portion 352, the blocking portion 358 can block the corresponding first roller 42, that is, restrict the movement of the first roller 42 from the front-back direction and the vertical direction (i.e., the first direction) of the drawer body 30.

[0041] In one embodiment, the box body 50 has, for example, two opposing uprights 51 and 52. Each upright has a first sliding component 53 on its inner surface, and the drawer body 30 has second sliding components 37 on the outer surfaces of its two transverse side walls 33 and 34. Both the first sliding component 53 and the second sliding component 37 extend along the longitudinal direction of the drawer body 30, and they are slidably engaged. Furthermore, a blocking portion is provided at the rear of the uprights 51 and 52 to prevent the drawer body 30 from exceeding its insertion limit when inserted into the box body 50.

[0042] In one embodiment, the box body is, for example, a Type II structure. Specifically, the box body 50 includes only two opposing upright plates 51 and 52, which are fixed to the inner liner 300. However, this invention is not limited to this. In this embodiment, the box body 50 is, for example, a U-shaped structure. In addition to the two opposing upright plates 51 and 52, the box body 50 also includes a bottom plate 56 connecting the two upright plates 51 and 52. The two upright plates 51 and 52 and the bottom plate 56 form a U-shaped tray. The drawer body 30 is slidably engaged by the first sliding component 53 and the second sliding component 37 within the box body 50 for free pushing and pulling. This solution can reduce the back side or even the bottom side wall of the insulated drawer, thereby saving costs and freeing up space to expand the drawer body 30 and increase the user's storage capacity. At the same time, the drawer body 30 is directly exposed in the storage space, which allows for better cold air transfer, better preservation, and reduces the frequency and duration of refrigeration operation, thus achieving energy-saving effects.

[0043] In addition, in this utility model, the drawer cover 40 will not move along the longitudinal direction (i.e., the front-to-back direction) of the drawer body 30 as the drawer body 30 pushes and pulls relative to the box body 50. Therefore, preferably, the drawer cover 40 also includes a first positioning part 45 extending outward from its plate 44, and the top 54 of the corresponding transverse side walls of the box body 50 (these transverse side walls correspond to the upright plates 51 and 52) has a second positioning part 55, and the first positioning part 45 and the second positioning part 55 are combined for positioning.

[0044] Furthermore, second rollers 38 are provided on both lateral side walls 33 and 34 of the drawer body 30. These second rollers 38 are located at the rear ends of the lateral side walls 33 and 34 of the drawer body 30 and near the top 31 of the drawer body 30. The second surface 46 of the drawer lid 40 has a concave arc-shaped portion 47 corresponding to the second roller 38. The second surface 46 is the surface of the drawer lid 40 facing the top opening 32. When the drawer body 30 and the drawer lid 40 are sealed, the second rollers 38 are located at the concave arc-shaped portion 47. The cooperation between the second rollers 38 and the concave arc-shaped portion 47 not only provides positioning for the seal between the drawer body 30 and the drawer lid 40, but also makes the sliding of the drawer lid 40 smoother when the drawer body 30 moves relative to the box 50.

[0045] In addition, a sealing strip 60 is provided between the drawer body 30 and the drawer lid 40. The sealing strip 60 is, for example, a silicone sealing strip, which can improve the sealing between the drawer body 30 and the drawer lid 40.

[0046] In addition, the drawer body also includes a front end plate 38 disposed on the front side of the drawer body 30.

[0047] In summary, this invention directly exposes the drawer body of the food storage drawer within the compartment, using only the drawer lid to form an openable, sealed structure (storage compartment). This allows for better cold air transfer, resulting in better preservation and reducing the frequency and duration of refrigeration operation, thus achieving energy savings. Furthermore, by placing the ventilation vents of the food storage drawer on the drawer lid, this invention ensures that the controlled atmosphere zone is only inside the drawer body, improving ventilation efficiency.

[0048] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described above can be combined with each other as long as they do not conflict with each other. It must be pointed out that the disclosed embodiments do not limit the scope of this utility model. On the contrary, any modifications and refinements made without departing from the spirit and scope of this utility model are within the patent protection scope of this utility model.
