[0030] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.

[0031] The embodiments of the utility model are described below with reference to the drawings. Figures 1 to 8 The drawer assembly and the refrigerator of the embodiment of the utility model are described.

[0032] As Figures 1 to 3 Indicated, the drawer assembly of the embodiment of the utility model includes: drawer 1, humidity adjusting cover plate 2 and cold storage element 3, the storage cavity 11 is equipped in drawer 1, humidity adjusting cover plate 2 is installed in the upside of drawer 1, in dehumidification condition, humidity adjusting cover plate 2 can absorb the moisture in air, in humidification condition, humidity adjusting cover plate 2 can release the moisture to air, cold storage element 3 is located in storage cavity 11, and cold storage element 3 absorbs and releases cold. It can be understood that cold storage element 3 can absorb and store cold in the low temperature environment of drawer 1, and cold storage element 3 can release cold when the temperature of drawer 1 is caused to rise in humidification condition.

[0033] According to the drawer assembly of the embodiment of the utility model, since the cold storage part 3 can absorb and release cold, when the humidifying cover plate 2 releases moisture into the air in the humidifying working condition, the temperature of the humidifying cover plate 2 will rise, and the cold storage part 3 releases cold, so that the temperature fluctuation in the humidifying process of the drawer assembly can be reduced, thereby the refrigeration effect of the drawer assembly can be improved.

[0034] It can be understood that when the drawer assembly is in the humidifying working condition, the humidifying cover plate 2 can heat by using the heating structure itself or heat the surrounding air by using the external heating structure, so that the moisture adsorbed by the humidifying cover plate 2 in the dehumidifying working condition is released in the form of temperature rise, and the cold storage part 3 can release cold in the humidifying working condition to compensate for the temperature rise of the humidifying cover plate 2, thereby the temperature fluctuation in the storage cavity 11 can be reduced.

[0035] In other words, when the refrigerator is in the normal refrigeration mode, the cold storage part 3 can store cold. When the drawer assembly needs to be humidified, the temperature of the humidifying cover plate 2 rises, at this time the cold storage part 3 can release the cold stored in the early stage to keep the temperature in the storage cavity 11 constant. When the drawer assembly humidification is completed, the cold storage part 3 can store cold under the refrigeration of the refrigerator for the next time the drawer assembly is humidified.

[0036] The selection of the dehumidifying working condition and the humidifying working condition of the drawer assembly can be manually controlled through the operation panel on the refrigerator, or automatically controlled according to the detection of the detection sensor in the drawer assembly, and the utility model does not limit this.

[0037] Optionally, as shown in Figure 3 The cold storage part 3 is at least two, that is, the cold storage part 3 can be two or more. The at least two cold storage parts 3 are arranged opposite to each other on the two sides of the storage cavity 11. Therefore, when the cold storage part 3 releases cold, the cold storage part 3 can uniformly diffuse the cold to the storage cavity 11, which is beneficial to keep the uniform consistency of the temperature in the storage cavity 11.

[0038] For example, the cold storage part 3 is two, and the two cold storage parts 3 are symmetrically arranged on the left and right sides of the storage cavity 11. It can be understood that the left and right directions of the storage cavity 11 are consistent with the left and right directions of the refrigerator. One cold storage part 3 is arranged on the left side of the storage cavity 11, and the other cold storage part 3 is arranged on the right side of the storage cavity 11, and the two cold storage parts 3 are symmetrically arranged. Compared with the scheme of arranging the two cold storage parts 3 on the front and rear sides or the upper and lower sides of the storage cavity 11, the uniform consistency of the temperature in each area of the storage cavity 11 can be improved, and the structure layout is reasonable, and the processing and assembly are convenient.

[0039] To realize the cold storage and release of the cold storage member 3, the cold storage member 3 can be made of a phase change cold storage material. The drawer assembly utilizes the cold stored by the phase change cold storage material to slow down the temperature fluctuation caused by the heating during the regeneration of the adsorption member 23, and is conducive to maintaining the stability of the temperature inside the storage cavity 11.

[0040] In an example, as shown in Figure 3 , the cold storage member 3 includes an inorganic hydrated salt solution 32 and a cold storage box 31, and the inorganic hydrated salt solution 32 is arranged in the cold storage box 31. It can be understood that the inorganic hydrated salt solution 32 can store cold in the refrigeration mode of the refrigerator, and when the drawer 1 is in the humidification working condition, the inorganic hydrated salt solution 32 undergoes phase change and releases cold, and the cold is transmitted to the outside of the storage cavity 11 through the cold storage box 31, thereby reducing the temperature fluctuation in the storage cavity 11.

[0041] For example, the cold storage box 31 can be fixed on the side wall of the drawer 1 in a clamping or threaded connection manner, so as to facilitate the assembly and disassembly of the cold storage member 3.

[0042] In some embodiments, as shown in Figure 5 , Figure 7 and Figure 8 , the humidifying cover plate 2 includes a frame layer 21, a heating member 22 and an adsorption member 23, the frame layer 21 is provided with an air outlet channel 211, the air outlet channel 211 is in communication with the storage cavity 11, the adsorption member 23 is arranged in the air outlet channel 211, and the heating member 22 is arranged adjacent to the adsorption member 23. The heating member 22 can heat the adsorption member 23 in the humidification working condition.

[0043] It can be understood that, as shown in Figures 6 to 8 , the air outlet channel 211 can discharge the cold air in the air duct of the refrigerator into the storage cavity 11 through the air outlet channel 211. Since the adsorption member 23 is arranged in the air outlet channel 211, when the drawer assembly is in the dehumidification working condition, the air flowing through the air outlet channel 211 can be dehumidified by the adsorption member 23, so as to reduce the humidity of the air entering the storage cavity 11, thereby achieving the effect of dehumidifying the storage cavity 11.

[0044] When the drawer assembly is in the humidification working condition, the moisture adsorbed by the adsorption member 23 is released under the heating action of the heating member 22, and then the released water molecules can enter the storage cavity 11 with the air under the flow guiding action of the air outlet channel 211, so as to increase the humidity of the air discharged by the air outlet channel 211 into the storage cavity 11, thereby improving the humidification effect of the storage cavity 11.

[0045] Optionally, as shown in Figure 5 and Figure 7 , the humidifying cover plate 2 further includes a cover layer 24, and the cover layer 24 is arranged on the frame layer 21.As shown, the heating element 22 comprises a heating layer 221 arranged on one side of the frame layer 21 in the thickness direction. The thickness direction of the frame layer 21 is consistent with the up-down direction of the refrigerator. Since the heating element 22 is in a layer structure, and the heating layer 221 is arranged on one side of the frame layer 21 in the thickness direction, the uniformity of heating by the heating element 22 can be improved, which is conducive to the moisture desorption effect of the adsorption element 23 in the frame layer 21, so that the humidification efficiency of the storage cavity 11 is higher.

[0046] As shown in Figure 5 and Figure 7 , the humidifying cover plate 2 comprises two heat preservation layers 24 arranged on both sides of the frame layer 21 in the thickness direction, and the heating element 22 is arranged between the two heat preservation layers 24. Therefore, the heat loss during heating of the heating element 22 can be reduced, the heat insulation effect of the humidifying cover plate 2 is improved, and the temperature fluctuation in the storage cavity 11 is reduced.

[0047] For example, the heat preservation layer 24 can be a foaming layer or a foam layer, and the heating layer 221 covers the lower side of the frame layer 21, and the heating area of the heating layer 221 is substantially equal to the lower end surface of the frame layer 21.

[0048] In an example, as shown in Figure 8 , the adsorption element 23 is a metal organic framework layer arranged on the inner wall of the air outlet channel 211. It can be understood that the adsorption element 23 is made of metal organic framework (MOFs) material, which is a kind of ultra-low density porous material, and can adsorb a large amount of water molecules in the dehumidification mode, and the adsorption element 23 can release water molecules after heating to dehumidify or humidify the air flowing through the air outlet channel 211, thereby prolonging the storage time of the goods in the drawer 1.

[0049] For the adsorption dehumidification material in the related art, since the saturation adsorption amount of the adsorption dehumidification material is limited and the regeneration desorption temperature is high, the adsorption dehumidification material is disposed after being saturated after a period of use, and cannot be recycled. The metal organic framework (MOFs) material has high saturation adsorption amount and low desorption regeneration energy, can be adsorbed by the change of relative humidity, and desorbed at a relatively low regeneration temperature, forming an adsorption-desorption cycle, which is conducive to prolonging the service life of the adsorption element 23.

[0050] For example, as shown in Figure 8 , the metal organic framework layer is fixed to the inner wall of the air outlet channel 211 by means of silica sol adhesion.

[0051] Optionally, as shown in Figures 6 to 8As shown, the air outlet channels 211 are multiple, and the multiple air outlet channels 211 are arranged in sequence along the left-right direction of the drawer 1, and the air outlet channels 211 extend along the front-rear direction of the drawer 1, the rear end of the air outlet channel 211 is used for communicating with the air duct of the refrigerator, and the front end of the air outlet channel 211 communicates with the storage cavity 11. It can be understood that the front-rear direction of the air outlet channel 211 is consistent with the front-rear direction of the refrigerator. The air in the air outlet channel 211 extends in the direction from the rear to the front, so that the cold air can enter the front side of the storage cavity 11 and then uniformly diffuse to the rear side of the storage cavity 11, thereby ensuring the uniformity of the temperature in the storage cavity 11.

[0052] As shown in Figure 7 and Figure 8 As shown, the frame layer 21 includes a frame body 212 and a support rib 213, the frame body 212 is provided with a sandwich layer, and the support rib 213 is arranged in the sandwich layer in a staggered manner, and the support rib 213 and the frame body 212 jointly enclose a plurality of air outlet channels 211. For example, the support rib 213 can be a plurality of X-shaped structures connected in sequence. The support rib 213 is arranged in the frame body 212 in a staggered manner, which can improve the structural strength of the frame layer 21 and reduce the weight of the frame layer 21, thereby facilitating the lightweight design of the humidity adjusting cover plate 2.

[0053] For example, the frame layer 21 is made of aluminum metal, thereby reducing the weight of the frame layer 21 and having good heat conduction effect.

[0055] According to the refrigerator of the embodiment of the present application, when the humidity adjusting cover plate 2 releases moisture into the air in the humidifying working condition, the temperature of the humidity adjusting cover plate 2 rises, and the cold storage part 3 releases cold energy, so as to reduce the temperature fluctuation in the humidifying process of the drawer assembly, thereby improving the refrigeration effect of the refrigerator.
