[0028] In one embodiment of the present application, a refrigerator is provided, including a main body provided with a cooling space, and also including a thawing device 100 as described in any of the following embodiments, and the thawing device 100 is located inside the main body, and the thawing device 100 is used to restore frozen food 200 to room temperature.

[0029] For ease of description, the present specification uses the X, Y, and Z directions that are perpendicular to each other as references for description, but not as a limitation, wherein the Z direction is the height direction, i.e., the up and down direction, the X direction is the distribution direction described below, and the Y direction is the extension direction described below.

[0030] See also Figure 1 , Figure 1 The cross-sectional structure diagram of the thawing device 100 in one embodiment of the present application is shown. The thawing device 100 provided in one embodiment of the present application is used to restore the frozen food 200 to room temperature, and it can be placed inside or outside the refrigerator. Figure 1 As shown, the thawing device 100 includes a drawer 110 and a placement plate 120. Optionally, the placement plate 120 is made of a high thermal conductivity material, such as an aluminum alloy.

[0031] In such Figure 1 In the illustrated embodiment, the thawing device 100 also includes a shell 130, in which a variable temperature space 131 is provided, and the drawer 110 and the placement plate 120 are located inside the variable temperature space 131, so as to isolate the food 200 through the shell 130, thereby reducing the contamination of the food 200 by external microorganisms, and the final state of the thawing of the food 200 can be adjusted by setting the temperature of the variable temperature space 131, thereby meeting the needs of different life scenarios.

[0032] The drawer 110 can move relative to the housing 130 in the distribution direction (i.e., the X direction in the figure) to enter or pull out of the temperature-changing space 131. Optionally, the housing 130 is provided with a slide rail 132 for sliding connection with the drawer 110, and the slide rail 132 is arranged along the distribution direction (i.e., the X direction in the figure) so that the drawer 110 can move relative to the housing 130 in the X direction.

[0033] Combination Figure 2 As shown, Figure 2 The schematic diagram of the exploded structure of the drawer 110 and the placement plate 120 of the thawing device 100 in one embodiment of the present application is shown. The drawer 110 includes a bottom plate 111 and a peripheral wall 112 connected to the bottom plate 111. The bottom plate 111 and the peripheral wall 112 together enclose a placement space 113 with an opening. The placement plate 120 can be placed in the placement space 113 through the opening. Figure 2 and Figure 3 As shown, the bottom plate 111 is provided with a convex strip 1111 arranged along the extension direction (i.e., the Y direction in the figure), and the convex strip 1111 is used to limit the placement plate 120 in the X direction when the drawer 110 moves relative to the shell 130, thereby preventing the placement plate 120 from shaking in the placement space 113 when the drawer 110 is pulled.

[0034] like Figure 2 and Figure 3As shown, the placement plate 120 is located in the placement space 113 and is placed on the bottom plate 111. The placement plate 120 includes a holding section 121 for placing food 200. The holding section 121 is provided with a plurality of upwardly bent portions 1211, so that when the food 200 is placed on the bending portion 1211, it only contacts with the top of the bending portion 1211, so as to reduce the contact area of ​​the bending portion 1211 with the food 200, and reduce the adhesion between the food 200 and the holding section 121, so as to easily pick up the food 200. At the same time, the bending portion 1211 can also be used for the finger to partially extend into the gap between the food 200 and the bending portion 1211 when placing the food 200, so as to further facilitate the picking up of the food 200.

[0035] like Figure 2 and Figure 3 As shown, each bending portion 1211 extends in the same direction as the convex strip 1111 (i.e., in the Y direction in the figure), and all the bending portions 1211 are distributed sequentially in the distribution direction (i.e., the X direction in the figure), the distribution direction (i.e., the X direction in the figure) is perpendicular to the extension direction (i.e., the Y direction in the figure), at least part of the bending portions 1211 are aligned with the convex strip 1111, and each convex strip 1111 is aligned with one bending portion 1211, that is, the number of the bending portions 1211 is not less than the number of the convex strips 1111.

[0036] like Figure 3 and Figure 4 As shown, when the placement plate 120 is placed on the bottom plate 111, the bent portion 1211 covers the convex strip 1111, and the bent portion 1211 and the convex strip 1111 abut against each other in the distribution direction (i.e., the X direction in the figure), so that the convex strip 1111 and the bent portion 1211 abut against each other in the X direction, so that the bottom plate 111 limits the placement plate 120 in the X direction when the drawer 110 is pulled relative to the shell 130, thereby preventing the placement plate 120 from shaking in the placement space 113 when the drawer 110 is pulled.

[0037] In one embodiment, the distance between adjacent bent portions 1211 is smaller than the distance between adjacent convex strips 1111, so that when the placement plate 120 is placed on the bottom plate 111, there is a gap between the bent portion 1211 that is not aligned with the convex strip 1111 and the bottom plate 111, so that there is a channel for air flow between the placement plate 120 and the bottom plate 111. It can be understood that when the food 200 is placed on the placement plate 120, the temperature of the placement plate 120 is also reduced due to the heat exchange between the low-temperature food 200 and the placement plate 120. When the airflow flows between the placement plate 120 and the bottom plate 111, the heat exchange between the bottom of the placement plate 120 and the airflow can be accelerated, thereby improving the efficiency of thawing the food 200.

[0038] like Figure 4As shown, in one embodiment, the convex strip 1111 and the bent portion 1211 are both arc-shaped structures, and the radius r of the convex strip 1111 is not greater than the radius R of the bent portion 1211, so as to avoid the instability of the abutment between the two when the bent portion 1211 is located against the convex strip 1111. Preferably, the radius r of the convex strip 1111 is slightly smaller than the radius R of the bent portion 1211, so as to avoid the occurrence of poor matching between the placement plate 120 and the bottom plate 111 due to manufacturing size deviation. In other embodiments, the convex strip 1111 can also be other shapes, such as triangular or polygonal structures.

[0039] like Figure 4 As shown, in one embodiment, the deformation height H of the ridge 1111 is not less than the deformation height h of the bending portion 1211, so that when the placement plate 120 is placed on the bottom plate 111, the top of the ridge 1111 abuts against the bending portion 1211, so that the contact between the ridge 1111 and the bending portion 1211 is closer, so that the placement plate 120 is stable when placed on the bottom plate 111.

[0040] like Figure 3 and Figure 5 As shown, in one embodiment, the bending portion 1211 is an arc-shaped structure, and the containing section 121 is a wave-like structure formed by a plurality of continuously distributed bending portions 1211, so that when the food 200 is placed at any position of the containing section 121, it can be easily taken out and the thawing efficiency is high.

[0041] like Figure 4 As shown, in one embodiment, the convex strips 1111 are in an arc-shaped structure, and the distance between adjacent convex strips 1111 is an integer multiple of the distance between adjacent bent portions 1211, so that each convex strip 1111 is provided with a corresponding bent portion 1211 to cooperate with it. In order to take into account the placement stability of the placement plate 120 and the thawing efficiency of the food 200, in this embodiment, the distance between adjacent convex strips 1111 is twice the distance between adjacent bent portions 1211. In other embodiments, the distance between adjacent convex strips 1111 is three times or more the distance between adjacent bent portions 1211.

[0042] like Figure 2 and Figure 5 As shown, in one embodiment, the placement plate 120 further includes a handle 123 and an extension section 122 located at the edge of the holding section 121, the extension section 122 extends from the holding section 121 in a direction away from the bottom plate 111, so as to prevent the food 200 from sliding out of the holding section 121 through the extension section 122, thereby preventing the food 200 from sliding off. The handle 123 is connected to one end of the extension section 122 away from the holding section 121, so that there is a gap between the handle 123 and the bottom surface, so as to facilitate taking the placement plate 120.

[0043] like Figure 1As shown, in one embodiment, the thawing device 100 further includes a fan 140 connected to the housing 130 and acting on the temperature-changing space 131. The fan 140 is located on the side of the drawer 110 with an opening and is arranged toward the placement plate 120. Figure 1 As shown, the fan 140 is located at the top of the variable temperature space 131 , and is used to accelerate the heat exchange between the food 200 and the environment in the variable temperature space 131 , thereby accelerating the rapid thawing of the food 200 .

[0044] Optionally, the thawing device 100 also includes a fan cover 150 connected to the shell 130, a space for placing the fan 140 is formed between the fan cover 150 and the shell 130, and the fan cover 150 has an air outlet connecting the inside and outside of the fan cover 150, and the fan cover 150 is used to protect the fan 140.

[0045] In the above scheme, by providing a plurality of bending portions 1211 in the holding section 121 of the placing plate 120 for holding the food 200, the food 200 is placed on the bending portion 1211 and only contacts the top of the bending portion 1211, thereby reducing the contact area of ​​the bending portion 1211 with the food 200, and reducing the adhesion between the food 200 and the holding section 121. At the same time, the bending portion 1211 can also be used for the fingers to partially extend into the food 200 and the bending portion 1211 when taking and placing the food 200. The food 200 can be easily taken out of the gap, and the area in which the food 200 and the placement plate 120 are in contact with the airflow is enlarged by the bending portion 1211, thereby improving the thawing efficiency. At the same time, a convex strip 1111 aligned with the bending portion 1211 is provided on the bottom plate 111 of the drawer 110, so that the convex strip 1111 and the bending portion 1211 can abut against each other in a distribution direction perpendicular to their extension direction, thereby preventing the placement plate 120 from shaking in the drawer 110 when the drawer 110 moves.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
