[0058] In some embodiments, the refrigeration system may include a compressor (not shown). The compressor may serve as a power source for the refrigeration cycle, sucking in low-temperature, low-pressure refrigerant gas and compressing it into high-temperature, high-pressure gas. The compressor may deliver high-temperature, high-pressure refrigerant to the condenser.

[0059] In some embodiments, the refrigeration system may include a condenser (not shown). The compressor may deliver the compressed refrigerant to the condenser. The condenser may condense high-temperature and high-pressure refrigerant vapor.

[0060] In some embodiments, the refrigeration system may include a throttling device (not shown). The condenser may deliver the condensed refrigerant to the throttling device.

[0061] In some embodiments, the refrigeration system may include an evaporator (not shown). The throttling device may deliver the throttled and depressurized refrigerant to the evaporator. The evaporator may be used to evaporate and boil the refrigerant vapor so as to absorb the heat of the surrounding medium.

[0062] In some embodiments, the compressor, the condenser, the throttling device, and the evaporator may be sequentially connected to form a refrigeration circuit, in which the refrigerant may circulate to achieve refrigeration of the interior of the box 11 .

[0063] In some embodiments, a press chamber (not shown) may be provided in the box body 1. The press chamber may be provided in the bottom area of ​​the box body 1. The press chamber may be located at the rear lower side of the storage compartment. A compressor, a condenser, a throttling device, etc. may be provided in the press chamber.

[0064] In some embodiments, an evaporator bin (not shown) may be provided in the housing 1. An evaporator may be provided in the evaporator bin. The evaporator may be used to absorb heat in the evaporator bin, so that a large amount of cold air is formed in the evaporator bin.

The freezing room 3 and the temperature-changing room 4 may be used to store objects with different temperature requirements. The preset refrigeration temperature of the freezing room 3 may be lower than the preset refrigeration temperature of the temperature-changing room 4.

[0068] like Figure 2 As shown, in some embodiments, the freezing chamber 3 may be provided with a freezing air outlet 301. The freezing air outlet 301 may transport the cold air in the freezing chamber 3 away from the inside of the freezing chamber 3.

[0069] Figure 3 This is a second schematic diagram of a freezing chamber and a temperature-changing chamber according to an embodiment of the present application; Figure 4 yes Figure 3 Exploded diagram of Figure 5 This is a third schematic diagram of a freezing chamber and a temperature-changing chamber according to an embodiment of the present application; Figure 6 yes Figure 3 Cross-sectional view of .

[0070] It should be noted that in order to facilitate the display of the structure inside the temperature-changing drawer, Figure 3 This is a schematic diagram after the front side panel of the temperature-changing drawer is hidden.

[0071] like Figure 3 and Figure 4 As shown, in some embodiments, the temperature-changing chamber 4 may be provided with a vent 401. The vent 401 may connect the interior of the temperature-changing chamber 4 with the outside.

[0072] like Figure 5 and Figure 6 As shown, in some embodiments, the vent 401 can be connected to the freezing air outlet 301. In this way, the variable temperature chamber 4 and the freezing chamber 3 can be connected through the vent 401 and the freezing air outlet 301, which is conducive to the cold air in the freezing chamber 3 to smoothly enter the variable temperature chamber 4, so as to achieve cooling in the variable temperature chamber 4.

[0073] like Figure 4 As shown, in some embodiments, the freezing chamber 3 and the variable temperature chamber 4 can be arranged adjacent to each other. The adjacent arrangement of the freezing chamber 3 and the variable temperature chamber 4 can optimize the position layout of the freezing chamber 3 and the variable temperature chamber 4, so that the cold air in the freezing chamber 3 can enter the variable temperature chamber 4 more quickly. Moreover, the adjacent arrangement facilitates the circulation of cold air and improves the refrigeration efficiency.

[0074] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigerator further includes a temperature-changing drawer 5. The temperature-changing drawer 5 can be arranged in the temperature-changing chamber 4, and the temperature-changing drawer 5 can be used to store food, thereby providing a flexible and convenient storage space for the refrigerator, so that the user can adjust the type and quantity of food in the drawer as needed.

[0075] In some embodiments, the temperature-changing drawer 5 is movably arranged in the temperature-changing chamber 4. In this way, the user can put food into the temperature-changing drawer 5 or take out food by taking out the temperature-changing drawer 5.

[0076] In some embodiments, the temperature-changing drawer 5 is drawably arranged in the temperature-changing chamber 4. The user can take the temperature-changing drawer 5 out of the temperature-changing chamber 4 by drawing it.

[0077] Figure 7 It is one of the temperature-changing drawers of an embodiment of the present application.

[0078] like Figure 4 and Figure 7 As shown, in some embodiments, a limiting rib 6 may be provided on the outer peripheral wall of the temperature-changing drawer 5. A sliding groove 402 may be provided on the inner wall of the temperature-changing chamber 4. The limiting rib 6 is adapted to the sliding groove 402. When the limiting rib 6 of the temperature-changing drawer 5 is inserted into the sliding groove 402 and moves to a position along the sliding groove 402, the temperature-changing drawer 5 can be set in the temperature-changing chamber 4. When the limiting rib 6 of the temperature-changing drawer 5 leaves the sliding groove 402, the temperature-changing drawer 5 can be taken out of the temperature-changing chamber 4.

[0079] like Figure 7As shown, in some embodiments, the temperature-changing drawer 5 may be provided with a first air inlet 501. The first air inlet 501 may be provided as an inlet for cold air to enter the interior of the drawer, so that the external cold air may fill the interior of the drawer through the first air inlet 501, thereby achieving refrigeration of the interior of the temperature-changing drawer 5.

[0080] like Figure 6 As shown, in some embodiments, the vent 401 is connected to the first air inlet 501, so that the cold air in the variable temperature chamber 4 can enter the variable temperature drawer 5, thereby directly cooling the interior of the variable temperature drawer 5, which is beneficial to improving the refrigeration efficiency.

[0081] In some embodiments, the cold air in the freezing chamber 3 can enter the temperature-changing drawer 5 through the freezing air outlet 301, the vent 401 and the first air inlet 501 in sequence. The air duct assembly provided inside the refrigerator can transport the cold air to the freezing chamber 3, and then flow to the vent 401 of the temperature-changing chamber 4 through the freezing outlet provided on the freezing chamber 3, and then enter the temperature-changing drawer 5 through the first air inlet 501. In this way, the cold air in the freezing chamber 3 can flow to the temperature-changing drawer 5, thereby reducing the loss and unnecessary circulation of the cold air in the temperature-changing chamber 4, and can quickly reduce the temperature in the drawer, reducing the loss and waste of the cold air during the transmission process. On the other hand, the cold air first flows through the freezing chamber 3 and then enters the temperature-changing chamber 4. In the process of passing through the freezing chamber 3, the cold air exchanges heat with the stored objects in the freezing chamber 3, so that the temperature of the cold air reaching the temperature-changing chamber 4 is higher than that of the cold air in the freezing chamber 3, thereby avoiding the temperature in the temperature-changing chamber 4 being too low, and at the same time, the temperature inside the temperature-changing drawer 5 can be cooled down, and the first temperature change of the temperature-changing drawer 5 can be realized. This can make fuller use of the cooling capacity of the cold air, thereby improving cooling efficiency and reducing energy consumption.

[0082] like Figure 4 and Figure 6 As shown, the refrigeration device of the present application can more effectively utilize the cold air from the freezer chamber 3 to change the temperature of the temperature-changing drawer 5 by directly providing a first air inlet 501 on the temperature-changing drawer 5, thereby improving the refrigeration efficiency; moreover, the air supply channel design in this solution is more compact, does not directly occupy the storage space and internal installation space of the refrigerator, and improves the space utilization rate of the refrigeration device.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, a freezing air outlet 301 may be provided on a side wall of the freezing chamber 3 adjacent to the variable temperature chamber 4. By arranging the freezing air outlet 301 close to one side of the variable temperature chamber 4, the cold air of the freezing chamber 3 can enter the variable temperature chamber 4 more quickly and directly.

[0084] In some embodiments, a vent 401 is provided on a side wall of the temperature-changing chamber 4 adjacent to the freezing chamber 3. By arranging the vent 401 close to one side of the freezing chamber 3, the temperature-changing chamber 4 is facilitated to receive cold air from the freezing chamber 3.

[0085] like Figure 4 As shown, in some embodiments, a freezing air outlet 301 may be provided on a side wall adjacent to the freezing chamber 3 and the temperature-changing chamber 4, and a vent 401 may be provided on a side wall adjacent to the temperature-changing chamber 4 and the freezing chamber 3. This can shorten the communication channel between the freezing chamber 3 and the temperature-changing chamber 4, reduce the resistance and leakage of cold air during transmission, and help reduce the heat loss of cold air, so that the cold air can quickly enter the temperature-changing chamber 4, thereby achieving cooling of the temperature-changing chamber 4 and the temperature-changing drawer 5 located in the temperature-changing chamber 4.

[0086] like Figure 5 and Figure 6 As shown, in some embodiments, the freezing air outlet 301 can be arranged opposite to the vent 401. In this way, the cold air flow path between the freezing chamber 3 and the variable temperature chamber 4 can be more compact, and after the cold air is ejected from the freezing air outlet 301, it can quickly enter the variable temperature chamber 4 through the vent 401, and form a relatively uniform cold air distribution inside the variable temperature chamber 4.

[0087] In some embodiments, an air passage (not shown in the figure) may be formed between the freezing chamber 3 and the variable temperature chamber 4. The freezing air outlet 301 and the vent 401 may be connected through the air passage. The air passage is provided between the freezing air outlet 301 of the freezing chamber 3 and the vent 401 of the variable temperature chamber 4, so that the cold air can flow to the variable temperature chamber 4 along the air passage, reducing the disordered diffusion of the cold air between the freezing chamber 3 and the variable temperature chamber 4, thereby guiding the flow of the cold air.

[0088] In some embodiments, the size of the wind passage and the corresponding sizes of the freezing air outlet 301 and the vent 401 can be designed according to the preset temperature of the variable temperature room 4. For example, for a variable temperature room 4 with a lower preset temperature, the size of the wind passage can be increased accordingly, and the sizes of the freezing air outlet 301 and the vent 401 can be increased accordingly, so that more cold air can flow from the freezing room 3 to the variable temperature room 4. For a variable temperature room 4 with a higher preset temperature, the size of the wind passage can be reduced accordingly, and the sizes of the freezing air outlet 301 and the vent 401 can be reduced accordingly, so that a large amount of cold air can be avoided from flowing from the freezing room 3 to the variable temperature room 4.

[0089] In some embodiments, the refrigerator is further provided with an air door (not shown in the figure). The air door is movably provided on the air passage. The movable design of the air door allows the user to adjust whether the cold air from the freezing chamber 3 flows to the variable temperature chamber 4 as needed. For example, the freezing air outlet 301 and the vent 401 are connected, or the connection between the freezing air outlet and the vent 401 is blocked.

[0090] In some embodiments, the damper can have a first state when it moves relative to the air passage. When the damper is in the first state, the damper can cover the vent 401 or the freezing air outlet 301 to block the cold air from the freezing chamber 3 from flowing along the vent 401 to the variable temperature chamber 4. When necessary, the temperature in the variable temperature chamber 4 is kept stable to prevent the food stored in the variable temperature chamber 4 from being frozen due to too low a temperature.

[0091] In some embodiments, the damper may have a second state relative to the movement of the wind passage. The damper connects the vent 401 and the freezing air outlet 301, so that the cold air of the freezing chamber 3 flows along the vent 401 toward the variable temperature chamber 4. At this time, the cold air of the freezing chamber 3 is allowed to flow toward the variable temperature chamber 4, so as to quickly reduce the temperature in the variable temperature chamber 4 when needed.

[0092] In some embodiments, when the real-time temperature in the variable temperature chamber 4 reaches a preset temperature, the damper can be controlled to move from the second state to the first state so that the cold air in the freezer chamber 3 cannot flow to the variable temperature chamber 4, thereby maintaining the variable temperature chamber 4 at a preset temperature.

[0093] In some embodiments, when too much food is stored in the variable temperature chamber 4, making the real-time temperature in the variable temperature chamber 4 higher than the preset temperature, the damper can be controlled to move from the first state to the second state, so that the cold air from the freezer 3 can flow to the variable temperature chamber 4, thereby cooling the variable temperature chamber 4, which is beneficial to maintaining the variable temperature chamber 4 within a relatively stable temperature range, thereby improving the preservation effect of the variable temperature chamber 4.

[0094] In some embodiments, the damper may also be disposed on a side wall of the freezing chamber 3 where the freezing air outlet 301 is disposed, and the damper may move relative to the freezing air outlet 301 to open or close the freezing air outlet 301 .

[0095] In some embodiments, the damper may also be disposed on the side wall of the variable temperature chamber 4 provided with the vent 401 , and the damper may move relative to the vent 401 to open or close the freezing air outlet 301 .

[0096] In some other embodiments, the freezing air outlet 301 and the ventilation opening 401 may be staggered, and an air passage may be added between the freezing air outlet 301 and the ventilation opening 401 so that the freezing air outlet 301 can flow toward the temperature-changing chamber 4 in a directional manner.

[0097] like Figure 4 and Figure 6 As shown, in some embodiments, the peripheral side wall of the temperature-changing drawer 5 may include a first side wall 51. The first side wall 51 may be arranged close to one side of the vent 401, and the first side wall 51 is provided with a first air inlet 501. By arranging the vent 401 close to the first air inlet 501, the distance of the cold air from the temperature-changing chamber 4 to the temperature-changing drawer 5 can be shortened, so that the cold air flow path between the two is more compact, and the cold air can enter the temperature-changing drawer 5 more effectively.

[0098] In some embodiments, the vent 401 can be arranged opposite to the first air inlet 501, so that the cold air from the vent 401 flows directly to the first air inlet 501 and enters the temperature-changing drawer 5. Since the first air inlet 501 directly faces the vent 401, it is beneficial for the cold air flowing out of the freezing chamber 3 to directly and efficiently enter the temperature-changing drawer 5, which can reduce the diffusion and loss of cold air in the temperature-changing chamber 4, improve the utilization rate of cold air, and enable the temperature in the temperature-changing drawer 5 to quickly and evenly reach the set value.

[0099] In some embodiments, the side wall where the vent 401 of the temperature-changing chamber 4 is located can enclose an air cavity with the first side wall 51 of the temperature-changing drawer 5. The air cavity can connect the vent 401 with the first air inlet 501, so that the cold air from the freezing chamber 3 can enter the temperature-changing drawer 5 through the air cavity after entering the vent 401.

[0100] It should be noted that, by forming an air cavity between the vent 401 of the variable temperature chamber 4 and the first side wall 51 of the variable temperature drawer 5, the setting of the air cavity can form a more uniform and stable cold air flow at the first air inlet 501 of the variable temperature drawer 5, and can also provide a clear path for the flow of cold air from the vent 401 to the first air inlet 501. In this way, the cold air can flow in the air cavity along the set direction, reducing the disordered diffusion and eddy phenomenon of the cold air in the variable temperature chamber 4, thereby enhancing the guidance of the cold air flow. Moreover, the setting of the air cavity plays a guiding role in the flow of cold air, which can further ensure that the cold air enters the interior of the variable temperature drawer 5 more effectively, thereby improving the refrigeration efficiency.

[0101] In some embodiments, the cold air in the freezing chamber 3 can enter the temperature-changing drawer 5 through the freezing air outlet 301 , the vent 401 , the air cavity and the first air inlet 501 in sequence.

[0102] In some embodiments, the side wall where the vent 401 of the temperature-changing chamber 4 is located and the first side wall 51 of the temperature-changing drawer 5 can be relatively spaced and enclosed to form an air cavity. Since the air cavity is enclosed by a side wall of the temperature-changing chamber 4 and a side wall of the temperature-changing drawer 5, the air cavity constitutes a relatively closed space. When the cold air enters the temperature-changing chamber 4 and is transported to the temperature-changing drawer 5, the enclosed structure of the air cavity reduces the leakage of the cold air during the transmission process, thereby effectively preventing the cold air from diffusing to the surrounding of the temperature-changing drawer 5 during the transmission process. This design is conducive to improving the utilization rate of the cold air and reducing energy consumption.

[0103] In some embodiments, an air supply structure may be provided in the air cavity, which can actively guide the flow direction and speed of the cold air in the air cavity, so that the cold air can enter the temperature-changing drawer 5 more accurately along a preset path.

[0104] In some embodiments, the air supply structure may be a fan, which may form a negative pressure in the air cavity when in operation, thereby accelerating the flow of cold air in the air cavity.

[0105] Figure 7 It is one of the temperature-changing drawers of an embodiment of the present application; Figure 8 This is the second temperature-changing drawer of an embodiment of the present application.

[0106] like Figure 6 and Figure 7 As shown, in some embodiments, the first air inlet 501 may include multiple ones. The provision of multiple first air inlets 501 can increase the number of inlets for cold air to enter the temperature-changing drawer 5, and the cold air can enter the interior of the drawer through the multiple air inlets more quickly, and perform heat exchange with the air in the temperature-changing drawer 5, so that the temperature in the temperature-changing drawer 5 drops rapidly. On the other hand, the distribution of multiple air inlets enables the cold air to cover a wider area in the temperature-changing drawer 5, reducing the local temperature unevenness caused by a single air inlet.

[0107] In some embodiments, the first air inlets 501 may be distributed at intervals on the first side wall 51 of the temperature change drawer 5 .

[0108] like Figure 6 As shown, in some embodiments, the plurality of first air inlets 501 may be distributed at intervals along a projection area of ​​the vent 401 projected onto the first side wall 51 .

[0109] It should be noted that the shape of the vent 401 is the same as the shape of its orthographic projection area on the first side wall 51. By distributing the plurality of first air inlets 501 at intervals along the projection area of ​​the orthographic projection of the vent 401 on the first side wall 51, the plurality of first air inlets 501 can be arranged opposite to the vent 401, shortening the flow path of the cold air from the vent 401 to the first air inlet 501, and further improving the delivery efficiency of the cold air to the inside of the variable temperature drawer 5.

[0110] In some embodiments, a plurality of first air inlets 501 may be distributed in the upper area of ​​the projection area of ​​the vent 401 directly projected on the first side wall 51. Properly setting the number of first air inlets 501 can prevent cold wind from causing the drawer temperature to drop too quickly, which may easily cause frost in the variable temperature drawer 5.

[0111] It should be noted that, in some other embodiments, the distribution positions of the plurality of first air inlets 501 can be arranged according to the temperature setting of the temperature-changing drawer 5. In some temperature-changing drawers 5 with lower temperature settings, the plurality of first air inlets 501 can be distributed throughout the projection area of ​​the vents 401 directly projected onto the first side wall 51.

[0112] In some embodiments, the first air inlet 501 may be designed in a rhombus shape. The rhombus-shaped design of the first air inlet 501 is conducive to achieving a more uniform air flow distribution. The rhombus shape has diffusivity in four directions, so that the cold air can cover the inside of the drawer more widely. Moreover, the rhombus-shaped first air inlet 501 has a stable and reliable structural strength, which improves the structural safety and reliability of the variable temperature drawer 5.

[0113] In some embodiments, the first air inlets 501 may be arranged along the length direction of the vent 401 to form a plurality of arrays. Any two arrays arranged adjacent to each other may be staggered so that the first air inlets 501 in one array are at least partially located between the two first air inlets 501 in the other array. The staggered arrays are advantageous for providing more first air inlets 501, which is advantageous for the temperature-changing drawer 5 to receive the cold air from the freezer 3 to a greater extent, and further enhancing the diffusion effect of the cold air inside the drawer.

[0114] like Figure 7 As shown, in some embodiments, the first air inlets 501 are arranged along the length direction of the vent 401 to form two upper and lower arrays, and the upper array is staggered with the lower array. Among them, between any two adjacent first air inlets 501 in the upper array, there is at least one first air inlet 501 in the lower array. This can not only improve the efficiency of cold air entering the temperature-changing drawer 5, but also improve the aesthetics of the temperature-changing drawer 5.

[0115] In some embodiments, the cold air entering the temperature variable drawer 5 through the first air inlet 501 can circulate in the space inside the temperature variable drawer 5, thereby cooling the temperature variable drawer 5.

[0116] like Figure 7 As shown, in some embodiments, the peripheral side wall of the temperature-changing drawer 5 may include a second side wall 52. The second side wall 52 may be arranged away from the side of the freezing chamber 3 having the vent 401, and the second side wall 52 may be provided with a second air inlet 502. The second air inlet 502 may allow part of the cold air inside the temperature-changing drawer 5 to flow out through the second air inlet 502.

[0117] Fig. 9 This is a third schematic diagram of a freezing chamber and a temperature-changing chamber according to an embodiment of the present application; Fig.10 Schematic diagram of a wind gap according to an embodiment of the present application.

[0118] like Fig. 9 and Fig.10 As shown, in some embodiments, an air gap 505 may be formed between the outer wall of the temperature-changing drawer 5 and the inner wall of the temperature-changing chamber 4, and the second air inlet 502 may be connected to the air gap 505, so that part of the cold air flowing into the temperature-changing drawer 5 along the first air inlet 501 may flow to the air gap 505 through the second air inlet 502. After the cold air enters the drawer through the first air inlet 501, part of the cold air may flow out through the second air inlet 502, enter the air gap 505, and then flow along the outer periphery of the temperature-changing drawer 5 to cool the temperature-changing drawer 5.

[0119] It should be noted that, when the temperature-changing drawer 5 is provided with both the first air inlet 501 and the second air inlet 502, part of the cold air flowing from the freezer chamber 3 into the temperature-changing drawer 5 can circulate inside the temperature-changing drawer 5, and then part of the cold air can flow through the second air inlet 502 to the wind gap 505 between the outer wall of the temperature-changing drawer 5 and the inner wall of the temperature-changing chamber 4, thereby more comprehensively and effectively cooling the temperature-changing drawer 5 and improving the utilization efficiency of the cold air.

[0120] like Fig. 9 As shown, in some embodiments, the number of the second air inlets 502 can be set to multiple. Each first air inlet 501 can be used as a channel for the cold air to flow out, and the provision of multiple second air inlets 502 can make the cold air more evenly distributed around the temperature-changing drawer 5. Moreover, when the type, quantity or position of the food loaded in the temperature-changing drawer 5 changes, the provision of multiple second air inlets 502 can better adapt to these changes. No matter how the food is placed, it can ensure that there are enough second air inlets 502 for the cold air to flow out, thereby maintaining a stable temperature inside the drawer.

[0121] like Figure 7As shown, in some embodiments, the first air inlet 501 can be arranged opposite to the second air inlet 502. In this way, a direct convection channel can be formed inside the temperature-changing drawer 5, which is conducive to enhancing the convection effect of cold air between the temperature-changing drawer 5 and the air gap 505, so that the cold air can flow and exchange more quickly. This helps to further improve the refrigeration efficiency, so that the temperature-changing drawer 5 can reach and maintain the set temperature more quickly.

[0122] like Figure 2 As shown, in some embodiments, the peripheral side walls of the temperature variable drawer 5 may include at least four side walls, wherein two of the four side walls are a first side wall 51 and a second side wall 52 that are oppositely arranged, the first side wall 51 may be provided with a first air inlet 501, and the second side wall 52 may be provided with a second air inlet 502, wherein the first side wall 51 and the second side wall 52 are oppositely arranged, and the first air inlet 501 and the second air inlet 502 may also be oppositely arranged.

[0123] It should be noted that, in some other embodiments, the first side wall 51 and the second side wall 52 can be arranged adjacent to each other, the first side wall 51 is provided with a first air inlet 501, and the second side wall 52 is provided with a second air inlet 502, which can also allow part of the cold air inside the temperature change drawer 5 to flow to the wind gap 505.

[0124] like Figure 8 As shown, in some embodiments, the bottom of the temperature-changing drawer 5 may be provided with wind shielding ribs 7. The provision of the wind shielding ribs 7 can further optimize the circulation path of the cold air between the temperature-changing drawer 5 and the temperature-changing chamber 4.

[0125] In some embodiments, the wind shield 7 may protrude relative to the bottom of the temperature-changing drawer 5 toward the inner wall of the temperature-changing chamber 4, and the wind shield 7 may prevent the cold air in the wind gap 505 from flowing out through the gap between the temperature-changing chamber 4 and the temperature-changing drawer 5. One end of the wind shield 7 is connected to the bottom of the temperature-changing drawer 5, and the other end of the wind shield 7 is stopped in the inner wall of the temperature-changing chamber 4. The wind shield 7 may block the gap between the temperature-changing chamber 4 and the temperature-changing drawer 5, and prevent the cold air in the wind gap 505 from being directly emitted to the outside of the temperature-changing chamber 4 through the gap between the temperature-changing chamber 4 and the temperature-changing drawer 5, thereby reducing the occurrence of problems such as uneven distribution of cold air and low circulation efficiency.

[0126] like Figure 8 As shown, in some embodiments, the wind shielding ribs 7 can be arranged along the length direction of the bottom of the temperature changing drawer 5.

[0127] In some embodiments, the temperature-changing drawer 5 may include a drawer body. The drawer body may be provided with a receiving cavity 503 inside, and the receiving cavity 503 is used to accommodate the objects to be refrigerated. The cold air flowing from the freezing chamber 3 to the temperature-changing drawer 5 can exchange heat with the objects to be refrigerated, thereby cooling the objects to be refrigerated.

[0128] like Figure 7 and Figure 8 As shown, in some embodiments, the top of the drawer body may be provided with an opening 504. The opening 504 may be communicated with the receiving cavity 503, so that the user may directly place the object to be refrigerated into the receiving cavity 503 of the drawer body through the opening 504.

[0129] In some embodiments, the temperature-changing drawer 5 may include a cover (not shown in the figure). The cover is detachably mounted on the opening 504. When the cover is mounted on the opening 504, the cover can effectively block external heat from entering the accommodating cavity 503, while reducing the cold air in the accommodating cavity 503 from being emitted outward through the opening 504, thereby preventing cold air from leaking. This can improve the heat preservation performance of the refrigeration device, maintain the freshness and taste of the food, and enable the refrigerated items to be stored at a suitable temperature for a longer period of time.

[0130] In some embodiments, a heat insulating material is further provided on the temperature changing drawer 5. The provision of the heat insulating material can keep the temperature changing drawer 5 warm, so that the temperature changing drawer 5 can be stably maintained at a preset temperature.

[0131] In some embodiments, the heat insulating material may be heat insulating foam. It should be noted that the heat insulating foam is a highly efficient heat insulating material with good heat preservation and insulation effects, and can reduce the cold energy in the temperature-changing drawer 5 from being dissipated outward.

[0132] In some embodiments, the heat insulating foam may be disposed in the cover body, and the heat insulating foam may reduce the cold wind in the drawer body from flowing out through the gap between the cover body and the drawer body.

[0133] In some embodiments, the thermal insulation foam may cover the opening 504 to prevent the drawer body from transferring cold to the outside through the opening 504. When the thermal insulation foam covers the opening 504, the thermal insulation foam forms an additional insulation layer, so that when the cold air enters the accommodating cavity 503 inside the drawer body, the cold air can effectively change the temperature of the temperature-changing drawer 5, and the temperature inside the temperature-changing drawer 5 can be kept at a lower temperature, thereby improving the utilization rate of the cold air and extending the shelf life of the food.

[0134] In some embodiments, the heat insulating foam can be arranged on the peripheral side wall of the drawer body. In this way, the heat insulating foam can wrap the four sides of the drawer body, so that the temperature-changing drawer 5 can achieve a better heat preservation effect.

[0135] In some other embodiments, the thermal insulation material may also be glass fiber, vacuum board, thermal insulation coating, etc.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
