[0059] The air guide structure 4 with different air outlet rates is arranged on the bottom wall of the drawer 1 along the flow direction of the hot air in the air duct 3, and the part with a larger air outlet rate can form a hot air flow swirl, thereby promoting the heat circulation in the drawer 1.

[0060] like Figure 2 As shown, along the flow direction of hot air in the air duct 3, in the figure, an air guide structure 4 with increased air outlet speed is set along the direction from the rear to the front of drawer 1.

[0061] Specifically, the air guide structure 4 includes through holes on the bottom wall of the drawer 1. The openings of the through holes increase in sequence along the flow direction of the hot air in the air duct 3. The air outlet rate can be easily adjusted by setting the size of the openings. Of course, more complex methods can also be used for control, such as setting a flow meter on the air guide structure.

[0062] like Figure 2 As shown, a first air guide structure 401 and a second air guide structure 402 are sequentially arranged on the bottom wall of drawer 1 along the direction of hot air flow. The first air guide structure 401 includes multiple sets of evenly arranged circular through holes. The multiple sets of circular through holes do not completely cover the left and right width or front and back length of the bottom wall of drawer 1. The second air guide structure 402 includes an elongated through hole. The opening width of the elongated through hole is larger than the diameter of the circular through hole. There is a gap between the second air guide structure 402 and the first air guide structure 401.

[0063] The hot air supply structure 2 is located inside the cabinet or on one side of the drawer 1, such as... Figure 1 and Figure 2 As shown, the hot air supply structure 2 is located on the rear side of the drawer 1. The bottom wall of the drawer 1 is provided with multiple sets of circular through holes evenly distributed near the rear side of the drawer 1. The diameter of the multiple sets of circular through holes is the same. A long strip-shaped through hole is provided near the front side of the drawer 1, extending along the left and right sides of the drawer 1. The length of the long strip-shaped through hole is not shorter than the width of the multiple sets of circular through holes of the first air guide structure 401.

[0064] The hot air supply structure 2 includes a first part connected to the rear wall of the drawer 1, and a second part extending from the lower end of the first part parallel to the bottom wall of the drawer 1.

[0078] Specifically, the air guide structure 4 includes through holes arranged on the bottom wall of the drawer 1, and the openings of the through holes arranged along the flow direction of the hot air in the air duct 3 are increased, i.e. from the front side to the rear side of the drawer 1, and the adjustment of the air outlet rates is simply realized by the arrangement of the opening sizes.

[0079] Of course, more complex means can also be used for regulation and control, such as arranging flow meters on the air guide structure.

[0080] The first air guide structure 401 and the second air guide structure 402 are arranged on the bottom wall of the drawer 1 in the direction of hot air flow, i.e. in the direction from the front side to the rear side of the drawer 1 in the drawing. The first air guide structure 401 has a smaller air outlet rate than the second air guide structure 402. The first air guide structure 401 comprises a plurality of groups of circular through holes arranged uniformly. The plurality of groups of circular through holes do not completely cover the range of the left and right side widths or the front and rear side lengths of the bottom wall of the drawer 1. The second air guide structure 402 comprises long strip-shaped through holes. The opening width of the long strip-shaped through holes is greater than the diameter of the circular through holes. A space is arranged between the second air guide structure 402 and the first air guide structure 401.

[0081] The hot air supply structure 2 is arranged on the front side of the drawer 1. The bottom wall of the drawer 1 is uniformly provided with a plurality of groups of circular through holes near the front side of the drawer 1. The plurality of groups of circular through holes have the same diameter. Long strip-shaped through holes are arranged along the left and right sides of the drawer 1 near the rear side of the drawer 1. The length of the long strip-shaped through holes is not shorter than the width of the plurality of groups of circular through holes of the first air guide structure 401.

[0082] The hot air supply structure 2 comprises a first part connected to the front wall of the drawer 1 and a second part extending parallel to the bottom wall of the drawer 1 from the lower end of the first part. The first part is internally provided with a heating structure and a fan. The second part is provided with an outlet. The air duct 3 is arranged parallel to the bottom wall of the drawer 1. The inlet of the air duct 3 is connected to the outlet of the second part.

[0083] The air duct 3 is integrally arranged with the bottom wall of the drawer 1. The bottom wall of the drawer 1 is the upper housing of the air duct 3. The outlet of the air duct 3 is arranged at the same position as the air guide structure 4.

[0084] Alternatively, the air duct 3 is arranged separately from the bottom wall of the drawer 1. The upper housing of the air duct 3 is provided with an outlet. The outlet of the air duct 3 is directly connected to the air guide structure 4 or connected to the air guide structure 4 through a connecting element.

[0085] The drawer 1 is provided with a sliding part. The cabinet body is internally provided with a sliding rail. The sliding part is connected to the sliding rail.

[0086] Embodiment 3

[0087] This embodiment is a further limitation or explanation of Embodiment 1 or Embodiment 2, and can be combined with them.

[0088] The first air guide structure 401 and the second air guide structure 402 described above can also be arranged in the following manner:

[0089] The second air guide structure 402 comprises a plurality of groups of circular through holes arranged uniformly, and the first air guide structure 401 comprises long strip-shaped through holes. The diameter of the circular through holes is greater than the opening width of the long strip-shaped through holes, so that the rate of the hot air introduced to the part of the bottom wall of the drawer 1 near the outlet of the air duct 3 is lower than that of the part far away, thereby ensuring the uniform heating of the inside of the drawer 1 and realizing the circulation of the hot air in the inside of the drawer 1.

[0090] Embodiment 4

[0091] This embodiment is a further limitation or illustration of Embodiment 1 or 2 or 3.

[0092] The hot air supply structure 2 described above can not be arranged at one side of the drawer 1, but at other positions inside the cabinet, for example, at the lower part inside the cabinet, the inner wall of the cabinet or other reasonable positions.

[0093] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above-mentioned embodiments are still within the scope of the present application.
