[0047] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0048] Reference below Figures 1-9 A storage device according to an embodiment of the present application is described.

[0049] It should be noted that the storage equipment in this embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has diverse structural forms and a wide range of applications.

[0050] The storage device includes a box body and a door body. The box body includes an outer shell, an inner liner and an insulation layer located between the outer shell and the inner liner. The outer shell cover is arranged outside the inner liner to play a protective role; the insulation layer can be a foam layer, which plays a heat preservation and buffering role; a cabin is formed between the outer shell and the inner liner, and the cabin is used to place machines such as compressors and circuit breakers.

[0051] The storage device of this application can be a TM two-door refrigerator.

[0052] like Figures 1-9 As shown, the storage device provided in the embodiment of the present application includes: a box body 1, an air inlet duct 2, a return air duct 3 and a damper 4.

[0053] like Figure 1 As shown, the box body 1 forms a freezing compartment 11 and a non-freezing compartment 12 , and a temperature-changing compartment 13 is provided in the non-freezing compartment 12 .

[0054] The freezing compartment 11 is used to store items that need to be kept at low temperatures, while the non-freezing compartment 12 is used to store items that are at room temperature or need to be temperature-controlled. The non-freezing compartment 12 can be a refrigeration compartment or a variable temperature compartment 13.

[0055] The temperature-changing chamber 13 may include one or more chambers.

[0056] Exemplarily, when there is only one temperature-changing chamber 13 , the air inlet duct 2 forms a portion of the side wall of the temperature-changing chamber 13 .

[0057] For example, when there are two variable temperature chambers 13 and there can be only one air inlet duct 2, the air inlet duct 2 can be located between the two variable temperature chambers 13 to simultaneously supply cooling to the two variable temperature chambers 13, while forming part of the side walls of the two variable temperature chambers 13, thereby improving the integration of the equipment and reducing the encroachment on the effective volume of the storage device.

[0058] For example, when there are multiple variable temperature rooms 13, the air inlet ducts 2 include multiple ones. The air inlet ducts 2 can be located between adjacent variable temperature rooms 13 to simultaneously supply cooling to the multiple adjacent variable temperature rooms 13 and simultaneously form part of the side walls of the multiple adjacent variable temperature rooms 13, thereby improving the integration of the equipment and reducing the encroachment on the effective volume of the storage equipment.

[0059] like Figure 2 and Figure 4As shown, the air inlet duct 2 is at least partially disposed in the non-freezing compartment 12 , and defines a temperature-changing compartment 13 together with the cabinet body 1 . In other words, the temperature-changing compartment 13 is located in the non-freezing compartment 12 .

[0060] A variable temperature compartment 13 is provided in the non-freezing compartment 12. The variable temperature compartment 13 is provided in the non-freezing compartment 12. The temperature of the variable temperature compartment 13 can be adjusted as needed to adapt to the storage conditions of different items.

[0061] Compared with the case where the temperature-changing compartment 13 is arranged in the freezing compartment 11, the temperature-changing compartment 13 is arranged in the non-freezing compartment 12, and the insulation layer of the temperature-changing compartment 13 can be thinned to reduce the encroachment on the effective volume of the storage device; compared with the storage device in which the temperature-changing compartment 13 is arranged separately, the temperature-changing compartment 13 is arranged in the non-freezing compartment 12, and the temperature-changing compartment 13 can partially utilize the cooling capacity of the non-freezing compartment 12 to reduce energy consumption.

[0062] like Figure 3 and Figure 4 As shown, the air inlet duct 2 has a first air inlet 2111 communicating with the freezing compartment 11 and a first air outlet 2112 communicating with the temperature-changing compartment 13 , and a regulating port 2121 is opened on the front wall of the air inlet duct 2 .

[0063] The two ends of the air inlet duct 2 are respectively connected to the variable temperature compartment 13 and the freezing compartment 11, so as to transfer the coldness of the freezing compartment 11 to the variable temperature compartment 13, so that the variable temperature compartment 13 does not need to be designed with a separate refrigeration system and temperature control system, which can effectively reduce the encroachment on the effective volume of the storage device.

[0064] Part or all of the air inlet duct 2 is located in the non-freezing compartment 12. The part of the air inlet duct 2 located in the non-freezing compartment 12 and the box body 1 together define a temperature-changing compartment 13. The air inlet duct 2 not only guides the air but also serves as a partition and enclosure, thereby reducing the encroachment on the effective volume of the storage device.

[0065] like Figure 3 As shown, an adjustment port 2121 is opened on the front wall of the air inlet duct 2. The adjustment port 2121 runs through the front wall of the air inlet duct 2. The adjustment port 2121 is used to supply part of the damper 4. The user can adjust the position of the damper 4 through the adjustment port 2121 to adjust the amount of cold entering the variable temperature chamber 13, thereby controlling the temperature inside the variable temperature chamber 13.

[0066] In this embodiment, the front wall of the air inlet duct 2 faces the door body of the storage device. By setting the adjustment port 2121 on the front wall of the air inlet duct 2, the user can adjust the position of the damper 4 by opening the door body of the storage device, which is convenient for operation.

[0067] like Figure 2As shown, the return air duct 3 has a second air outlet 31 communicating with the freezing compartment 11 and a second air inlet 32 communicating with the temperature changing compartment 13 .

[0068] The two ends of the return air duct 3 are connected to the freezing compartment 11 and the temperature-changing compartment 13 respectively. The return air duct 3 can be located outside the freezing compartment 11 and the temperature-changing compartment 13. A return air duct is formed inside the return air duct 3 to help circulate air in the temperature-changing compartment 13 and improve the temperature uniformity inside the temperature-changing compartment 13.

[0069] like Figure 3 、 Figure 4 and Figure 5 As shown, the damper 4 is movably installed in the air inlet duct 2 and is at least partially located at the regulating port 2121 . The portion of the damper 4 located at the regulating port 2121 can move relative to the regulating port 2121 to adjust the air outlet area of the first air outlet 2112 .

[0070] The damper 4 is movably installed in the air inlet duct 2 . The portion of the damper 4 located at the regulating port 2121 can move relative to the regulating port 2121 under the action of an external force to adjust the air outlet area of the first air outlet 2112 .

[0071] The portion of the damper 4 located in the adjustment opening 2121 can slide along the extension direction of the adjustment opening 2121, and the adjustment opening 2121 acts as a limit and a guide groove. The end of the damper 4 can be located in the adjustment opening 2121, or it can pass through the adjustment opening 2121 and extend outside the adjustment buckle for easy adjustment.

[0072] In the storage equipment in the related art, a separate temperature control device is required to control the temperature in the variable temperature zone. The temperature adjustment is relatively complicated and the cost is high, and it needs to be improved.

[0073] According to the storage device provided in the embodiment of the present application, an air inlet duct 2 is provided, and the air inlet duct 2 and the box body 1 jointly define a variable temperature chamber 13, and an adjustment port 2121 is opened on the front wall of the air inlet duct 2, and the damper 4 is movably installed on the air inlet duct 2 and is at least partially located at the adjustment port 2121. The user can directly move the damper 4 at the adjustment port 2121 to adjust the air outlet area of the first air outlet 2112, thereby adjusting the cooling capacity of the variable temperature chamber 13 to control the temperature inside the variable temperature chamber 13.

[0074] In some embodiments, as Figure 4As shown, the air inlet duct 2 includes an inner duct bracket 21 and a connecting duct 22. An air inlet duct is formed in the inner duct bracket 21. The connecting duct 22 has a first air inlet 2111 connected to the freezing compartment 11 and a third air outlet connected to the non-freezing compartment 12. The inner duct bracket 21 has a first air outlet 2112 connected to the temperature-variable compartment 13 and a third air inlet connected to the air port of the connecting duct 22. The inner duct bracket 21 is located in the non-freezing compartment 12 and is detachably connected to the inner wall of the non-freezing compartment 12.

[0075] Among them, such as Figure 4 As shown, the two ends of the connecting air duct 22 are respectively connected to the freezing compartment 11 and the non-freezing compartment 12 , and the two ends of the inner air duct bracket 21 are respectively connected to the connecting air duct 22 and the temperature-changing compartment 13 .

[0076] The inner air duct bracket 21 is detachably connected to the box body 1. For example, the inner air duct bracket 21 can be connected to the inner wall of the box body 1 by at least one of the connection methods such as snap connection, plug connection and thread connection.

[0077] For example, when the space in the freezer compartment 11 is insufficient and the variable temperature compartment 13 needs to be used to increase the freezer space, or when the temperature in the freezer compartment 11 is too low and the temperature in the refrigeration compartment is too high to meet the storage requirements of the items, the inner air duct bracket 21 and the box body 1 can be assembled to form the variable temperature compartment 13 in the refrigeration compartment, thereby increasing the usage scenarios.

[0078] For example, when the temperature-variable compartment 13 is not needed, the assembly of the inner air duct bracket 21 and the box body 1 can be decoupled to increase the volume of the refrigeration compartment.

[0079] In some embodiments, as Figure 6 As shown, the inner air duct support 21 includes an air duct body 211 and an air duct shell 212 sleeved on the air duct body 211 . The air duct body 211 is connected to the freezing compartment 11 through the connecting air duct 22 .

[0080] The air duct shell 212 is detachably connected to the box body 1. For example, the air duct shell 212 can be connected to the inner wall of the box body 1 by at least one of the connection methods such as snap connection, plug connection and thread connection.

[0081] Exemplarily, the air duct housing 212 can be connected to the inner wall of the box body 1 by means of snap connection and threaded connection, thereby improving the stability of the connection.

[0082] In some embodiments, as Figure 6 、 Figure 7 and Figure 9 As shown, a clamping member 2126 is provided on one side of the air duct housing 212 , and a clamping groove 121 adapted to the clamping member 2126 is provided on the inner wall of the non-freezing compartment 12 .

[0083] In some embodiments, as Figure 9 As shown, the rear wall of the slot 121 is formed with a protruding piece protruding toward the front side of the box body 1, and the end of the protruding piece is spaced from the front wall of the slot 121; the clamping piece 2126 has a groove portion clamped with the protruding piece.

[0084] In this embodiment, the snap-fitting piece of the air duct shell 212 is first inserted into the snap-fitting slot 121 from the gap between the end of the protruding piece and the front wall of the slot opening of the snap-fitting slot 121, and then the air duct shell 212 is pushed toward the rear side of the refrigerator so that the groove portion and the protruding piece are snap-fitted, thereby completing the assembly of the air duct shell 212 and the box body 1; the assembly and decoupling process can be performed in reverse.

[0085] In some embodiments, as Figure 7 As shown, multiple groups of the clamping members 2126 and the clamping grooves 121 can be provided to achieve multi-point connection between the air duct housing 212 and the inner wall of the non-freezing compartment 12, thereby improving the stability of the connection between the two.

[0086] For example, the air duct housing 212 can be fastened to the inner wall of the non-freezing compartment 12 by four sets of fasteners 2126 and the fastening grooves 121 , and fixed to the inner wall of the non-freezing compartment 12 by two screws.

[0087] In some embodiments, as Figure 3 and Figure 6 As shown, the air inlet duct 2 includes: a duct body 211 and a duct shell 212; the duct body 211 has a first air inlet 2111 and a first air outlet 2112; the duct shell 212 is mounted outside the duct body 211 and is spaced from at least part of the duct body 211 to form a slide, the duct shell 212 is provided with a vent 2122 aligned with the first air outlet 2112, and the front wall of the duct shell 212 has an adjustment port 2121; wherein, part of the damper 4 is movably installed on the slide to adjust the air outlet area of the air outlet and the vent 2122.

[0088] An air inlet is formed in the air duct body 211 , and the cold energy in the freezing compartment 11 can flow into the air inlet from the first air inlet 2111 and be discharged into the temperature-changing compartment 13 through the first air outlet 2112 .

[0089] The damper 4 is sandwiched between the duct body 211 and the duct shell 212. A slide is formed between the duct body 211 and the duct shell 212. The slide provides a sliding space and a sliding track for the movement of the damper 4. The structure is simple and the stability and reliability of the movement of the damper 4 are improved.

[0090] The damper 4 is partially movable and installed in the slideway. The damper 4 can adjust its position as needed to change the air outlet area of the first air outlet 2112 and the vent 2122. The adjustment of the damper 4 can be achieved by manual or automatic control.

[0091] In some embodiments, as Figure 3 As shown, the storage device further includes: a drawer 5, which is installed in the temperature-changing chamber 13, and the drawer 5 is slidably connected to the box body 1 and the air inlet duct 2 respectively.

[0092] In this embodiment, the drawer 5 is slidably connected to the box body 1 and the air inlet duct 2 respectively, so as to facilitate taking out and putting out items.

[0093] The drawer 5, the air inlet duct 2 and the box body 1 together form a temperature-changing chamber 13, and the air inlet duct 2 and the box body 1 form side walls of the temperature-changing chamber 13 to reduce the encroachment on the effective volume of the storage device.

[0094] In some embodiments, a cover is provided on the front side of the drawer 5 , and the cover is detachably connected to the drawer 5 to seal the temperature-changing chamber 13 .

[0095] The drawer 5 is pivotally connected to the cover to facilitate taking out and putting out items from the temperature-changing chamber 13 .

[0096] In some embodiments, a slide rail is provided on the outer wall of the drawer 5, and a slide groove is provided on the side wall of the box body 1 and the air duct shell 212 facing the drawer 5. The slide rail is slidably connected to the slide groove to improve the convenience of taking and putting objects from the variable temperature chamber 13.

[0097] In some embodiments, as Figure 3 As shown, the air duct shell 212 includes a first shell portion 2124 and a second shell portion 2125 distributed along the height direction, the width of the second shell portion 2125 along the left and right directions is smaller than the width of the first shell portion 2124 along the left and right directions, the drawer 5 is located on one side of the second shell portion 2125, and the air duct body 211 is located on the first shell portion 2124.

[0098] Among them, the width of the second shell 2125 along the left and right direction is smaller than the width of the first shell 2124 along the left and right direction. The second shell 2125 is used to avoid the drawer 5, and the first shell 2124 is used to install the air duct body 211, which can not only meet the installation requirements of the air duct body 211, but also increase the volume of the drawer 5, and facilitate the assembly of the drawer 5.

[0099] In some embodiments, as Figure 1 As shown, the freezing compartment 11 is located above the non-freezing compartment 12, and the temperature-changing compartment 13 is located on the top of the non-freezing compartment 12, thereby shortening the length of the connecting duct 22 and the return air duct 3, reducing the loss of cooling capacity, reducing the encroachment on the effective volume of the storage device, and facilitating assembly.

[0100] In some embodiments, as Figure 8As shown, the damper 4 includes: a baffle 41 and an adjusting member 42; the baffle 41 is movably installed on the air inlet duct 2; the adjusting member 42 includes a connecting portion 421 and a protrusion 422 protruding from the connecting portion 421, the connecting portion 421 is connected to the baffle 41, and a part of the protrusion 422 is movably set at the adjusting port 2121 to drive the baffle 41 to adjust the air outlet area of the first air outlet 2112 and the ventilation port 2122.

[0101] The blocking member 41 can move on one side of the first air outlet 2112 driven by the protrusion 422 . The blocking member 41 can be a baffle structure, and the area of the blocking member 41 is not less than the ventilation area of the first air outlet 2112 .

[0102] like Figure 5 and Figure 8 As shown, the protrusion 422 protrudes from the connecting portion 421. The protrusion 422 can be designed in different shapes and sizes as needed to adapt to the size and shape of the adjustment port 2121. The protrusion 422 is partially movable in the adjustment port 2121 and can drive the position of the stopper 41 to change by moving.

[0103] The connecting portion 421 and the blocking member 41 may be connected by means of snap connection, plug-in connection, or integral molding.

[0104] In this embodiment, a user can move the protrusion 422 through external operation, thereby driving the stopper 41 to adjust the air outlet area of the air outlet and the vent 2122. The user can manually adjust the area, such as by turning a knob, a slide bar, or directly turning the knob, or automatically adjust the area, such as by a motor controlled by an electronic signal.

[0105] In some embodiments, as Figure 5 As shown, the top end of the protrusion 422 protrudes from the front wall of the air inlet duct 2 to facilitate users to move the protrusion 422.

[0106] In some embodiments, the blocking member 41 and the adjusting member 42 are detachably connected.

[0107] Exemplarily, the blocking member 41 and the adjusting member 42 may be connected by at least one of a snap-fit connection and a plug-in connection to facilitate assembly.

[0108] In some embodiments, as Figure 8As shown, one of the end of the stopper 41 and the inner side of the adjusting member 42 is provided with a card slot 411, and the other of the end of the stopper 41 and the inner side of the adjusting member 42 is provided with a protrusion 423, and the protrusion 423 cooperates with the card slot 411; the adjusting member 42 includes a first part and a second part connected, the first part is provided with a protrusion 422, the second part is located on one side of the stopper 41 and is provided with a limiting groove, and the side wall of the stopper 41 facing the second part is provided with a limiting protrusion, and the limiting groove cooperates with the limiting protrusion; the side wall of the stopper 41 facing the second part is provided with a limiting rib 413, and the limiting rib 413 stops at at least one end of the second part.

[0114] In this embodiment, the multi-point connection and cooperation structure of the stopper 41 and the adjusting member 42 in which the protrusion 423 cooperates with the slot 411 and the limiting rib 413 cooperates with the second part can increase the stability of the connection between the stopper 41 and the adjusting member 42.

[0115] In some embodiments, the adjusting member 42 includes a first part and a second part that are connected, the first part is provided with a protrusion 422, the second part is located on one side of the block 41 and is provided with a limiting groove, the block 41 is provided with a limiting protrusion on the side wall facing the second part, and the limiting groove cooperates with the limiting protrusion; the block 41 is provided with a limiting rib 413 on the side wall facing the second part, and the limiting rib 413 stops at at least one end of the second part.

[0116] In this embodiment, the multi-point connection structure of the stopper 41 and the adjusting member 42 through the cooperation between the limiting groove and the limiting protrusion and the stopper rib 413 and the second part can increase the stability of the connection between the stopper 41 and the adjusting member 42.

[0117] In some embodiments, one of the end of the stopper 41 and the inner side of the adjusting member 42 is provided with a card slot 411, and the other of the end of the stopper 41 and the inner side of the adjusting member 42 is provided with a protrusion 423, and the protrusion 423 cooperates with the card slot 411.

[0118] The end of the stopper 41 may be provided with a slot 411 , and the inner side of the adjusting member 42 may be provided with a protrusion 423 ; or the end of the stopper 41 may be provided with a protrusion 423 , and the inner side of the adjusting member 42 may be provided with a slot 411 .

[0119] In this embodiment, the end of the stopper 41 and the inner side of the adjusting member 42 are connected to the card slot 411 through the protrusion 423, which can limit the end of the stopper 41 and the adjusting member 42 and improve the stability of the connection between the stopper 41 and the adjusting member 42.

[0120] In some embodiments, the adjusting member 42 includes a first part and a second part that are connected, the first part is provided with a protrusion 422, the second part is located on one side of the block 41 and is provided with a limiting groove, and the side wall of the block 41 facing the second part is provided with a limiting protrusion, and the limiting groove cooperates with the limiting protrusion.

[0121] In this embodiment, the overlapping portion of the stopper 41 and the adjusting member 42 cooperates with the limiting protrusion through the limiting groove, which can increase the stability of the connection between the stopper 41 and the adjusting member 42.

[0122] In some embodiments, the adjusting member 42 includes a first part and a second part that are connected, the first part is provided with a protrusion 422, the second part is located on one side of the block 41, and the side wall of the block 41 facing the second part is provided with a limiting rib 413, and the limiting rib 413 is stopped at at least one end of the second part.

[0123] The limiting rib 413 limits the stopper 41 , reducing the risk of the protrusion 422 of the adjustment member 42 falling off from the adjustment opening 2121 and the separation of the stopper 41 and the adjustment member 42 , thereby improving the stability of the connection between the two.

[0124] As described above, the blocker 41 and the adjusting member 42 can be provided with multiple ones through which the protrusion 423 cooperates with the slot 411, the limiting slot cooperates with the limiting protrusion, and the limiting rib 413 cooperates with the second part to further increase the stability of the connection between the blocker 41 and the adjusting member 42.

[0125] In some embodiments, as Figure 5 As shown, the inner wall of the air duct shell 212 is provided with a guide rib 2123, which extends along the sliding direction of the adjusting member 42, and the front side of the guide rib 2123 is evenly spaced with at least two gear grooves; the adjusting member 42 is provided with a protrusion 423, and the part of the end portion of the protrusion 423 along the left and right directions is slidably matched with the front side of the guide rib 2123, and the part of the end portion of the protrusion 423 along the left and right directions is located in the slot 411.

[0126] The guide ribs 2123 are used to limit the movement trajectory of the protrusion 423 and provide a reminder for adjusting the gear position.

[0127] The user controls the protrusion 423 to slide along the front side of the guide rib 2123. When the protrusion 423 moves into the gear slot, there will be a change in the motion state, which can remind the user to reach the corresponding gear.

[0128] The notch of the gear slot faces the front side, and there may be two or more gear slots. The protrusion 423 is located in different gear slots. The damper 4 has different blocking areas for the first air outlet 2112, so that the amount of cold air discharged from the first air outlet 2112 to the variable temperature chamber 13 is different, thereby providing more temperature gears for the variable temperature chamber 13 and improving the application scenarios of the variable temperature chamber 13.

[0129] The width of the protrusion 423 along the left-right direction is greater than the width of the slot 411 along the left-right direction. The protrusion 423 is partially located inside the slot 411 and partially located outside the slot 411 and slidingly cooperates with the front side of the guide rib 2123 .

[0130] In some embodiments, as Figure 5As shown, the guide ribs 2123 include multiple guide ribs 2123, and the multiple guide ribs 2123 are evenly distributed along the sliding direction of the adjusting member 42; the two end surfaces of the guide rib 2123 are inclined surfaces 21231 and are smoothly connected to the side surfaces of the guide rib 2123 facing the protrusion 423, and the distance between the two inclined surfaces 21231 decreases from the direction away from the protrusion 423 to the direction close to the protrusion 423; two adjacent guide ribs 2123 form a gear groove.

[0131] The two inclined surfaces 21231 of the guide rib 2123 form an angle less than or equal to 90° from the extension line thereof, so that the notches of the gear slots formed by two adjacent guide ribs 2123 face the front side.

[0132] In this embodiment, by providing multiple guide ribs 2123, two adjacent guide ribs 2123 form gear slots, which can increase the number of gear slots, facilitate multi-gear adjustment of the temperature in the variable temperature chamber 13, and reduce processing difficulty.

[0133] In some embodiments, as Figure 5 As shown, the end of the protrusion 423 is smoothly connected to the side wall of the protrusion 423.

[0134] Exemplarily, the end of the protrusion 423 may be an arc-shaped, semicircular, or arc-shaped boss, so as to improve the smoothness of the movement of the protrusion 423 on the front side of the guide rib 2123 .

[0135] In some embodiments, as Figure 3 and Figure 4 As shown, the first air outlet 2112 is located at the front side of the air inlet duct 2 close to the temperature changing chamber 13 , and the second air inlet 32 is located at the rear side of the temperature changing chamber 13 .

[0136] In this embodiment, by locating the first air outlet 2112 near the front of the cabinet 1, the length of the damper 4 can be shortened, and the structural strength of the damper 4 can be improved. This increases the stability of the damper 4 during adjustment, improving the accuracy of the adjustment. Furthermore, by locating the first air outlet 2112 and the second air inlet 32 at the front and rear of the variable temperature compartment 13, the air flow path can be optimized, allowing cold air to circulate effectively between the freezing compartment 11 and the variable temperature compartment 13, thereby improving the temperature uniformity within the variable temperature compartment 13.

[0137] In some embodiments, as Figure 3 As shown, the front wall of the air inlet duct 2 has two adjustment ports 2121; the temperature-changing chambers 13 include two, at least part of the air inlet duct 2 is arranged between the two temperature-changing chambers 13, and the dampers 4 include two, at least part of the two dampers 4 are located in the two adjustment ports 2121 in a one-to-one correspondence.

[0138] In this embodiment, the air inlet duct 2 can provide cooling to the two temperature-changing chambers 13 at the same time. By setting two air doors 4, the two temperature-changing chambers 13 can be individually temperature-controlled, meeting the user's new demand for classified and zoned storage of items.

[0139] Compared with the structure of setting a single temperature-changing chamber 13 in the related art, the present application can reduce the situation where different categories of items are easily mixed with each other due to centralized storage; compared with the structure of setting multiple temperature-changing chambers 13 in the related art but with the same temperature control for the multiple temperature-changing chambers 13, the present application can meet the temperature requirements of different categories of items.

[0140] The portion of the air inlet duct 2 between the two temperature-changing chambers 13 forms at least a portion of the side walls of the two temperature-changing chambers 13 , thereby improving the integration of the storage device and reducing the occupation of the effective volume of the storage device.
