Description

Technical Field

[0002] In some application scenarios, refrigerators can keep meat ingredients warm and fresh by designing drawers to form relatively independent storage spaces. However, in related designs, when cooling the ingredients inside the drawer, cold air is usually blown into the drawer, and the cold air is blown directly onto the surface of the ingredients. The air inlet and outlet of the drawer are located at the back of the drawer near the inner tank. After the cold air enters the drawer, it mostly flows through the back area of the drawer, which results in a large amount of local cooling in the drawer, leading to phenomena such as over-freezing of meat ingredients and growth of ice crystals causing fat oxidation. In addition, the use of a large amount of cold air blowing directly onto the ingredients will also take away a large amount of moisture contained in the ingredients during the refrigeration process, causing the quality of the ingredients to deteriorate.

[0044] On the one hand, the present utility model provides a refrigerator, which includes a box body, an inner liner, a refrigeration system and a drawer device.

[0045] The box body adopts a cuboid hollow structure and is configured as the outer shell of the refrigerator. It can be understood that the box body can also adopt a hollow shell structure of other shapes. Multiple mutually separated refrigerating compartments can be arranged inside the box body, and each separated refrigerating compartment can be used as an independent storage space, such as a freezer, a refrigerator compartment and a variable temperature compartment, etc., to meet different refrigeration requirements such as freezing, refrigerating and variable temperature according to different types of food ingredients and to store them. The multiple refrigerating compartments can be arranged in an up-and-down separation or a left-and-right separation.

[0046] The inner liner is arranged inside the box body. The refrigerating compartment is formed inside the inner liner. It should be noted that multiple inner liners can be provided. Only one refrigerating compartment or multiple refrigerating compartments can be arranged inside the same inner liner.

[0047] The box body includes a box shell and a box door arranged on the front side of the box shell. The box door is used to open and close the refrigerating compartment. The box door and the box shell can be connected by a hinge so that the box door of the refrigerator can rotate around the axis of the hinge to realize the opening and closing of the box door, and then open and close the corresponding refrigerating compartment. It can be understood that multiple box doors can be provided and are arranged in one-to-one correspondence with the refrigerating compartments. Multiple box doors can also open and close one refrigerating compartment at the same time.

[0048] The refrigeration system is used to provide cold air inside the inner liner, and then realize the freezing and refrigerating functions. The refrigeration system mainly includes a compressor, a condenser, an evaporator and a air supply duct. The air supply duct is communicated with the refrigerating compartment to deliver cold air to the refrigerating compartment. Among them, the air supply duct is provided with an air outlet and an air return opening on the inner liner.

[0049] The drawer device is arranged inside the refrigerating compartment and has an air inlet and an air outlet. Among them, the air inlet is communicated with the air outlet, and the air outlet is communicated with the air return opening. In this way, the refrigeration system transports the cold air through the air outlet and the air inlet into the drawer device, and exchanges heat with the food ingredients and the like inside the drawer device to cool the food ingredients. The air after heat exchange returns to the air supply duct or is discharged to the outside through the air outlet and the air return opening.

[0050] The refrigerator can keep food such as meat warm and fresh by designing a drawer device to form a relatively independent storage space. However, in related designs, when cooling the food inside the drawer, cold air is usually blown into the drawer device, and the cold air is blown directly onto the surface of the food. The air inlet and outlet of the drawer are both located at the back of the drawer device and close to the inner tank. After the cold air enters the drawer device, it mostly flows through the back area of the device, which results in a large local cooling capacity of the drawer device, leading to phenomena such as over-freezing of meat food and ice crystal growth causing fat oxidation. In addition, the method of blowing a large amount of cold air directly onto the food will also take away a large amount of moisture contained in the food during the refrigeration process, causing the quality of the food to deteriorate.

[0051] In order to solve the above problems, the present application has optimized the structure of the drawer device, which can not only achieve rapid cooling of the food in the drawer device, but also reduce the loss of water in the food, so as to maintain the quality of the food for a longer period of time.

[0052] Please refer to Figures 1 to 3 In the embodiment of the present application, the drawer device 1 includes a cabinet 10 and a drawer body 20; the cabinet 10 encloses a receiving cavity 101 having an opening 102 on the front side. Specifically, the cabinet 10 includes two side panels 11 arranged opposite to each other in the left-right direction, a top panel 12 and a bottom panel 13 arranged opposite to each other in the up-down direction, and a back panel 14 covering the rear sides of the side panels 11, the top panel 12, and the bottom panel 13. Thus, the two side panels 11, the top panel 12, the bottom panel 13, and the back panel 14 together enclose the receiving cavity 101, and the front sides of the two side panels 11, the top panel 12, and the bottom panel 13 together define an opening 102. It should be noted that each of the side panels 11, top panel 12, bottom panel 13 and back panel 14 can be a single panel or multiple panels, such as a double-layer panel or a multi-layer panel structure, and the panels in the side panels 11, top panel 12, bottom panel 13 and back panel 14 can be split structures and then spliced, or a module formed by a whole large panel through bending, cutting and other processes, but the module has different panel parts corresponding to the side panels 11, top panel 12, bottom panel 13 and back panel 14, or the different panel parts corresponding to the side panels 11, top panel 12, bottom panel 13 and back panel 14 are formed into an integral module by casting, and this application does not limit this. And the material of the panel of the above structure can be plastic or metal. When the material is metal, it can be aluminum alloy, iron alloy and other materials.

[0053] For further information, please refer to Figures 3 to 5The cabinet 10 is also provided with an air supply cavity 103, an air inlet 104, an air outlet 105, a first air supply cavity 106 and a second air supply cavity 107. The air inlet 104 is connected to the air supply cavity 103, the air outlet 105 is connected to the accommodating cavity 101, and the first air supply cavity 106 is connected to the air supply cavity 103 and the accommodating cavity 101. Specifically, the air inlet 104 is provided on the rear wall of the cabinet 10, that is, the air inlet 104 is provided on the back plate 14, so that it is easy to dock with the air outlet of the inner tank wall of the refrigerator on the rear side of the cabinet 10. In some refrigerator structures, the drawer device 1 of the present application can be adapted to the refrigerator to be made into a full-width or half-width half-side drawer form. Therefore, in order to make the product form universal, the air inlet 104 of the present application can be provided at a position biased to one side of the back plate 14 along the left-right direction, such as the position biased to the left side as shown in the figure. It should be noted here that the left and right directions can be understood as the directions corresponding to the left and right sides of the user when the user stands facing the refrigerator directly in front of the refrigerator, the front and back directions can be understood as the direction in which the drawer body 20 enters and exits the cabinet 10, and the up and down directions are perpendicular to the left and right directions and the front and back directions.

[0054] The drawer body 20 includes a main body 21 and an end cover 22 connected to the front side of the main body 21. The main body 21 is slidably connected to the cabinet 10 and can be accommodated in the accommodating cavity 101, and the end cover 22 can cover the opening 102. Among them, a storage groove 211 with an upward opening 102 is formed on the main body 21 to hold food, and a sliding track can be provided between the outer wall of the main body 21 opposite to the cavity wall of the accommodating cavity 101 in the left and right directions, and the main body 21 and the cabinet 10 are slidably connected through the sliding track.

[0055] In one embodiment, an air induction groove 221 is further provided in the end cover 22, and the air induction groove 221 is connected at the upper and lower ends of the end cover 22, and the upper end of the air induction groove 221 is connected to the second air supply port 107. After the drawer body 20 enters the cabinet 10, the present application defines a return air chamber 108 (see FIG. 1 ) between the outer wall surface of the drawer body 20 and the cavity wall surface of the accommodating cavity 101 and connected to the exhaust port 105. Figure 5 ), the main body 21 of the present application is a slot structure that is open upward, and the return air chamber 108 is defined between the outer wall surface of the multiple walls constituting the main body 21 and the cavity wall surface of the accommodating cavity 101. Among them, the lower end of the air induction groove 221 is connected to the return air chamber 108, that is, the air induction groove 221 is used to guide the cold air delivered by the second air supply port 107 into the return air chamber 108, and then discharged from the exhaust port 105.

[0056] Specifically, an air inlet 222 of the air duct 221 is provided on the upper end surface of the end cap 22, and an air outlet 223 of the air duct 221 is provided on the lower end surface of the end cap 22. Among them, the air inlet 222 and the air outlet 223 can be in the form of long strip-shaped openings and extend in the left-right direction of the end cap 22. For example, the air inlet 222 and the air outlet 223 can be a continuous opening extending from the left edge to the right edge of the end cap 22, or can be composed of several spaced long strip-shaped openings, and also be an opening extending from the left edge to the right edge of the end cap 22. The advantage of such a setting is that the air duct 221 can cover the entire return air chamber 108 with cold air as large as possible, and the cold air in the return air chamber 108 exchanges heat with the main body 21, so as to effectively cool the food materials in the drawer body 20.

[0057] The opening shape of the second air supply port 107 on the wall of the cabinet body 10 can be the same as the opening shape of the air inlet 222, or the opening shape of the second air supply port 107 can also be different from the opening shape of the air inlet 222. For example, the second air supply port 107 can also be in the form of a whole long strip-shaped through hole, or in the form of multiple spaced long strip-shaped through holes, or the second air supply port 107 can be composed of multiple spaced small through holes. Of course, in order to achieve better air supply into the air duct 221, in one setting form, the second air supply port 107 extends from the left edge of the top plate 12 to the right edge of the top plate 12, so as to make the opening size of the second air supply port 107 match the air inlet 222 in the left-right direction, so as to achieve efficient passage of cold air through the air duct 221.

[0058] Based on the above embodiments, by providing a ventilation cavity 103 within the wall of the cabinet body 10, and arranging a first air outlet 106, an air exhaust port 105 and a second air outlet 107 on the wall of the cabinet body 10, and further providing an air guiding groove 221 in the drawer body 20. Thus, during actual use, a part of the refrigerating air blown into the ventilation cavity 103 from the air inlet 104 by the refrigerator enters the accommodation cavity 101 through the first air outlet 106, and this part of the air flow blows out towards the storage groove 211 inside the cabinet body 10, so as to flow through the upper surface of the food materials in the storage groove 211 and move towards the air exhaust port 105. Another part of the refrigerating air flow can enter the air guiding groove 221 through the second air outlet 107, and is guided between the outer wall surface of the drawer body 20 and the cavity wall surface of the accommodation cavity 101, and finally flows towards the air exhaust port 105. It can be seen that the refrigerating air flow in the accommodation cavity 101 realizes two paths of flow, and can directly contact the food materials for cooling and indirectly contact the food materials through the drawer body 20 for indirect cooling, so as to achieve cooling of both the upper surface and the lower part of the food materials at the same time, thus achieving the purpose of rapid cooling. And because of the solution of the present application, not all of the refrigerating air sent into the accommodation cavity 101 by the refrigerator is used to directly blow the food materials, so that it can effectively avoid the situation of excessive water loss of the food materials during the cooling process, which is beneficial to ensuring the quality of the food materials for a long time.

[0059] In addition, in the present application, since the air guiding groove 221 is provided in the end cover 22 of the drawer body 20, thus, during actual use, the refrigerating air can be sent to the position where the end cover 22 is located, and moves in the front-back direction in the accommodation cavity 101 and finally flows towards the air exhaust port 105. This can effectively overcome the problem in the traditional structural design that there is a lack of cold quantity at the position of the end cover 22, resulting in too high temperature at this place, so that when storing food materials for a long time, especially for meat food materials, it is easy to cause the food materials to spoil and deteriorate.

[0060] It should also be noted here that when the air groove outlet 223 is opened on the lower end surface of the end cover 22 and covers the length direction of the lower end surface of the end cover 22, it can be ensured as much as possible that there is cold air between the bottom surface of the drawer body 20 and the outer wall surface of the accommodation cavity 101 for heat exchange. Of course, in other embodiments, the air groove outlet 223 may not be on the lower end surface of the end cover 22, but may be on at least one of the left and right side surfaces of the end cover 22, or exist on at least one of the left and right side surfaces and the lower end surface of the end cover 22 at the same time. In this way, it can also realize the cold quantity transfer between the cold air and the wall of the main body 21, and indirectly cool the food materials in the storage groove 211.

[0061] In order to achieve more balanced cooling of the food ingredients in the storage groove 211, that is, to make the temperature more balanced at various places in the accommodation cavity 101, the first air supply port 106 and the air discharge port 105 of the present application are spaced apart in the left-right direction of the cabinet body 10. Thus, a part of the cooling air blown into the air supply cavity 103 from the air inlet 104 of the refrigerator can move horizontally in the left-right direction of the cabinet body 10 and move toward the air discharge port 105, and another part of the cooling air entering the air guiding groove 221 through the second air supply port 107 moves in the front-back direction in the accommodation cavity 101 and finally flows toward the air discharge port 105. It can be seen that the cooling air flow in the accommodation cavity 101 covers two directions, the left-right direction and the front-back direction. In this way, the cooling air flow can effectively cover the entire space in the accommodation cavity 101. In this way, each part of the drawer body 20 accommodated in the accommodation cavity 101 can better exchange heat with the cooling air and is relatively balanced during the cooling process. Thus, the effects such as the fresh-keeping function achieved are better.

[0062] In one embodiment, please refer to Figures 5 to 7 , the first air supply port 106 is opened on the top wall of the accommodation cavity 101 and is disposed adjacent to one side wall of the accommodation cavity 101 in the left-right direction. Combining the above content, the air supply cavity 103 in this embodiment can be arranged in the top plate 12, that is, the top plate 12 can include at least two layers of plate bodies spaced apart in the up-down direction. Among them, the air supply cavity 103 is formed between the two layers of plate bodies, and the first air supply port 106 is opened on the lowermost layer of the plate body of the top plate 12, that is, on the top wall of the accommodation cavity 101. With such a setting, on the one hand, the cold air in the air supply cavity 103 can be blown downward through the first air supply port 106, that is, the cold air is conveyed downward from top to bottom into the storage groove 211 of the drawer body 20. Moreover, in this embodiment, the first air supply port 106 and the air discharge port 105 can be respectively located at the left and right opposite sides of the accommodation cavity 101. In this way, after the first air supply port 106 enters the accommodation cavity 101, it flows from one edge of the accommodation cavity 101 to the other edge in the left-right direction, realizing comprehensive heat exchange for the food ingredients in the storage groove 211.

[0063] In order to make the cold air entering from the first air supply port 106 fully contact with the food in the drawer body 20, the first air supply port 106 of the present application is located on one side of the accommodating cavity 101 in the left-right direction, and is further extended in the front-to-back direction. Preferably, there is a first air supply port 106 that exceeds half of the accommodating cavity 101 in the front-to-back direction and is close to the opening 102, and the first air supply port 106 extends to the cavity rear wall close to the accommodating cavity 101, that is, extends to the position adjacent to the back plate 14. With this arrangement, during operation, the cold air can fully contact the food adjacent to the end cover 22 of the drawer body 20, which can effectively overcome the problem of the drawer body 20 being too hot due to lack of cold air flow at the position adjacent to the end cover 22 in the existing structure, and better achieve contact with the upper surface of the food in the entire accommodating groove 211 for cooling.

[0064] In one implementation form, the first air supply port 106 may include a plurality of air supply holes, and the plurality of air supply holes are arranged at intervals from the opening 102 to the rear side of the cabinet 10. The setting of the plurality of air supply holes has the advantage that the flow rate of the cold air can be reduced in the process of entering the accommodating chamber 101 through the air supply holes, so that in the process of cooling the food, too much moisture carried by the food will not be taken away, so that the quality of the food itself can be maintained for a long time. In this embodiment, the air supply holes can be set to a diameter range of 5 mm to 10 mm, and the number of air supply holes can be set to 4, 5, 6, 7, 8, etc. at intervals, so that the flow rate of the cold air can be limited within a reasonable range, and the flow rate required for cooling can also be ensured, but this part of the cold air cooling is used as an auxiliary cooling, so that the loss of moisture in the food can be minimized. In other embodiments, the first air supply port 106 can also be set to a narrow and long opening form to meet the requirements of flow rate and flow, and this application does not limit this.

[0065] In other embodiments, the air supply cavity 103 may not be disposed only in the top plate 12, but may be partially disposed in the top plate 12, while another portion of the air supply cavity 103 may be disposed in the side plate 11, or even in the bottom plate 13. The advantage of this is that since the air supply cavity 103 exists on the top plate 12, the side plate 11, and even the bottom plate 13, cold air flows, so that the cabinet 10 can directly transfer the cold to the drawer body 20 through heat exchange between the walls, and further use it to cool down the food. In this way, the drawer body 20 has more ways to exchange heat, thereby improving the cooling effect.

[0066] In addition, the first air supply opening 106 of the present application may also be provided on the side wall of the accommodation cavity 101 and is located near the top wall of the side wall of the cavity, so as to ensure that the air flow blown out from the first air supply opening 106 can fully enter the storage groove 211 of the drawer body 20 and perform sufficient heat exchange with the food materials.

[0067] Of course, when the air supply cavity 103 only exists on the top plate 12 and the first air supply opening 106 is also provided on the top wall of the accommodation cavity 101, the volume of the cabinet body 10 can be prevented from being too large, or in other words, the volume of the accommodation cavity 101 can be made larger, so as to achieve the purpose of containing more food materials. The following content will continue to be developed in the manner that the air supply cavity 103 is located on the top plate 12, and both the first air supply opening 106 and the second air supply opening 107 are located on the top wall of the accommodation cavity 101.

[0068] Furthermore, the air exhaust opening 105 may be provided on the other side wall of the accommodation cavity 101 in the left-right direction and adjacent to the bottom wall of the accommodation cavity 101, or the air exhaust opening 105 is provided on the bottom wall of the accommodation cavity 101. That is to say, the air exhaust opening 105 of the present application may be provided on the bottom plate 13 or on another side plate 11 far from the first air supply opening 106, and the air exhaust opening 105 is adjacent to the back plate 14. Thus, it can meet the requirement that the cold air blown into the accommodation cavity 101 from the first air supply opening 106 moves horizontally left and right, so that on the basis of sufficient heat exchange on the upper surface of the food materials, the air flow blown to the bottom of the main body 21 through the second air supply opening 107 and the air guiding groove 221 will flow in the front-back direction along the outer wall surface of the main body, so that the cold quantity directly penetrates into the food materials in the storage groove 211 through the wall body of the drawer body 20, thereby achieving the purpose of rapid cooling.

[0069] It can be seen that through the arrangement of the air supply cavity 103 and the first air supply opening 106 in the solution of the embodiment of the present application, part of the cold air directly contacts the upper surface of the food materials to achieve the purpose of sufficient heat exchange, while the other part of the cold air flows through the bottom outer wall surface of the drawer body 20 to penetrate into the interior of the drawer body 20. In this way, different from the form of directly blowing all the cold air against the food materials in the related design, it can achieve the purpose of rapid cooling and can also take away as little moisture of the food materials as possible, so as to maintain the freshness of the food materials for a long time.

[0070] It should also be noted here that on the basis of the present application achieving the cooling of the drawer body 20 by implementing two cold air flow paths, in addition to the exemplary illustration in the figure where the first air supply opening 106 is arranged on the left side of the entire air supply chamber 103, and the second air supply opening 107 is arranged on the front side of the air supply chamber 103 and adjacent to the opening 102, it is also possible that both the first air supply opening 106 and the second air supply opening 107 are arranged on the front side of the air supply chamber 103 and adjacent to the opening 102. In this case, the first air supply opening 106 can be arranged behind the second air supply opening 107, or both the first air supply opening 106 and the second air supply opening 107 are in the form of air supply holes and are staggeredly arranged in the same row. The present application does not limit this. Thus, under such a design, two airflows can also be formed, and both airflows flow in the front-rear direction and finally converge at the air discharge opening 105. In this way, it is also possible to achieve the transfer of cold quantity to the upper and lower sides of the food in the drawer body 20, achieving the effects of rapid cooling and minimizing water loss as much as possible.

[0071] Next, continue to take the example where the first air supply opening 106 is arranged on the left side of the entire air supply chamber 103 and the second air supply opening 107 is arranged on the front side of the air supply chamber 103 to further expand the solution of the present application. In order to more accurately distribute the cold air in the air supply chamber 103 to the first air supply opening 106 and the second air supply opening 107, please refer to Figures 5 to 7 again. The drawer device 1 of the present application further includes a wind guiding component 40. The wind guiding component 40 is arranged in the air supply chamber 103 to divert the cold air blown into the air supply chamber 103 through the air inlet 104 so as to blow towards the first air supply opening 106 and the second air supply opening 107. That is, through the arrangement of the wind guiding component 40 in this embodiment, the flow of the cold air in the air supply chamber 103 is reasonably intervened, so that the above effects can be more easily achieved.

[0072] It should be noted here that the wind guiding component 40 is not necessarily required in the solution of the present application. That is, the present application can, to a certain extent, solve the deficiencies existing in the prior art through the design of the above two air flow paths. For example, when both the first air supply opening 106 and the second air supply opening 107 are arranged on the front side of the air supply chamber 103 and adjacent to the opening 102, the wind guiding component 40 can also not be provided. In this case, the air inlet 104 located at the rear side of the entire air supply chamber 103 can blow cold air towards the front side, and the cold air can respectively enter the first air supply opening 106 and the second air supply opening 107.

[0073] The following content will be further expanded with the case where the wind guiding component 40 is provided.

[0074] In one embodiment, the air guiding assembly 40 includes an air duct member 41; the air duct member 41 defines a diversion channel 413, the diversion channel 413 includes an air inlet 414 and an air outlet 415, the air inlet 414 is connected to the air inlet 104, the opening area of the air outlet 415 is set to be larger than that of the air inlet 414, and in the left-right direction of the cabinet 10, the opening of the air outlet 415 extends from a position adjacent to the first air supply port 106 towards a direction away from the first air supply port 106. Taking the first air supply port 106 as the right side of the top wall of the accommodation cavity 101 in the perspective layout in the figure, and the second air supply port 107 extending on the front side of the top wall as an example, the right edge of the air outlet 415 of the present application is arranged adjacent to the first air supply port 106, and the opening of the air outlet 415 faces the second air supply port 107, and there is a certain interval between the air outlet 415 and the second air supply port 107 in the front-back direction. Thus, based on the wall attachment effect of fluid mechanics, part of the air flow blown out from the second air supply port 107 will escape outward from its right side and thus flow towards the first air supply port 106. Of course, when the air outlet 415 faces the second air supply port 107, most of the air flow will flow towards the second air supply port 107. Since the solution of the present application is to let a small part of the air flow enter the accommodation cavity 101 from the first air supply port 106 and contact the upper surface of the food material, while most of the air flow flows through the outer wall surface of the drawer body 20 and indirectly transfers the cold quantity to the food material, this can achieve effective cooling while minimizing the loss of moisture in the food material as much as possible.

[0075] In one setting form, the air duct member 41 includes a first rib 411 and a second rib 412 that are spaced apart in the air supply cavity 103, and the diversion channel 413 is defined between the first rib 411 and the second rib 412;

[0076] Among them, the second rib 412 is located between the first rib 411 and the first air supply port 106, and the end of the second rib 412 far from the air inlet 104 is arranged adjacent to the first air supply port 106. The end of the first rib 411 far from the air inlet 414 is closer to the air inlet 104 in the left-right direction of the cabinet 10. In this embodiment, in the form of ribs, the diversion channel 413 can be defined together with the cavity wall of the air supply cavity 103, which has the advantages of simple structure, easy production and low cost. Of course, in other embodiments, the air duct member 41 can also be in the form of an air duct.

[0077] As mentioned above, the first air supply port 106 includes a plurality of air supply holes arranged from the position of the opening 102 to the position of the back plate 14, and in order to allow the airflow to fully enter each air supply hole, especially the air supply hole located behind the air outlet 415, the end of the second rib 412 of the present application away from the air inlet 104 is bent toward the side away from the opening 102 and the first rib 411. By such a configuration, the wall attachment effect of the airflow is fully utilized, and part of the airflow can be effectively directed to the side of the back plate 14, so as to enter the air supply holes arranged near the back plate 14.

[0078] Furthermore, the second air supply port 107 of the present application extends in the left-right direction and is in the form of a long and narrow opening. Therefore, since the opening width of the air outlet 415 is smaller than the width of the second air supply port 107 in the left-right direction, there may be a situation where the airflow flowing toward the second air supply port 107 cannot enter from the entire opening area well. For this reason, the air guide assembly 40 further includes a flow divider 42, which is arranged at a position adjacent to the opening 102 of the air supply cavity 103 and is arranged opposite to the air outlet 415 in the front-to-back direction.

[0079] The flow divider 42 is used to divide the airflow from the air outlet 415 to the opening 102 to form an airflow portion directed toward the first air supply port 106 and an airflow portion directed away from the first air supply port 106 .

[0080] Specifically, the diverter 42 includes two guide surfaces 421 at an angle, wherein one guide surface 421 faces the first air supply port 106, and the other guide surface 421 faces away from the first air supply port 106, wherein the guide surface 421 facing away from the first air supply port 106 will be able to guide the airflow away from the first air supply port 106, that is, move along the length direction of the second air supply port 107, so that the airflow flowing to the second air supply port 107 can be effectively spread out, so that the entire opening area of the second air supply port 107 can be filled with cold air as much as possible, thereby achieving the purpose of wrapping the outer surface of the main body 21 of the entire drawer body 20 with cold air.

[0081] In addition, in order to enable the cold air to fill the air supply chamber 103, so that the cold quantity can radiate from the top wall of the entire accommodation chamber 101 to the position below the top wall of the accommodation chamber 101, there is an air passing gap between one ends of the first rib 411 and the second rib 412 facing the air inlet 104 and the back plate 14, and the air passing gap communicates the air supply chamber 103 and the drainage channel 413. Through the setting of this air passing gap in this embodiment, on the basis of arranging the air duct member 41, the cold air can quickly contact the rear position of the entire cabinet 10, so as to effectively cover the top wall of the entire accommodation chamber 101, and further achieve the purpose of effectively radiating the cold quantity to the upper surface of the food materials located in the accommodation chamber 101.

[0082] In one embodiment, the drawer device 1 further includes a sealing ring 50; the sealing ring 50 is arranged on the end cover 22 or the cabinet 10. When the end cover 22 closes the opening 102, the sealing ring 50 is arranged around the opening 102 and is clamped between the end cover 22 and the cabinet 10. The sealing ring 50 in this embodiment can be arranged on the end cover 22. Through the setting of the sealing ring 50, the leakage of the cold air in the accommodation chamber 101 can be effectively avoided.

[0083] In order to improve the convenience of use, the drawer device 1 of the present application can further be provided with a storage box 60 and a placing tray 70 that are used in cooperation with the drawer body 20. The storage box 60 and the placing tray 70 can be placed in parallel in the storage groove 211 of the main body 21 and can be taken and placed. Among them, the height of the placing tray 70 is lower than the height of the storage box 60. In this way, when both the placing tray 70 and the storage box 60 are located in the storage groove 211, the two will not interfere with each other and there is an operation space for taking and placing.
