[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 10 As shown, the refrigeration device provided by the present invention includes a box body 1, in which an air duct assembly 2 is provided for realizing air cooling, and the box body 1 is provided with a plurality of refrigeration compartments divided by partitions as needed, for example: the box body 1 is divided into a freezer compartment 101, a refrigerator compartment 102 and a third greenhouse 103. Among them, for special items, during the refrigerated storage process, not only the temperature is required, but also the storage humidity is required. In order to improve the storage environment with controllable temperature and humidity, a drawer assembly 5 with independent temperature and humidity control functions is provided in the third greenhouse 103. The drawer assembly 5 includes a heat-conducting barrel 51, a drawer 52, a humidifying water box 53 and a fan 54. The heat-conducting barrel 51 is arranged in the third greenhouse 103, and a partition 510 is provided in the heat-conducting barrel 51 to divide the interior of the heat-conducting barrel 51 into independent storage areas and an installation area, wherein the partition 510 is further provided with a ventilation hole (not marked) connecting the storage area and the installation area, the heat-conducting barrel 51 is provided with a cold air inlet 5111 and a cold air outlet 5112 in the storage area, the drawer 52 is arranged in the storage area, the humidifying water box and the fan are located in the installation area, the fan 54 is installed on the ventilation hole, the fan 54 includes a fan for blowing air into the storage area, and a humidity sensor 501 linked to the fan 54 is arranged in the storage area.

[0030] Specifically, items with storage requirements for humidity are placed in the drawer 52, and the drawer 52 slides into the storage area. The cold air output from the air outlet of the air duct assembly 2 in the third greenhouse 103 enters the storage area of ​​the heat transfer barrel 51 through the cold air inlet 5111 to cool the items in the drawer 52. The cold air after heat exchange in the storage area is discharged from the heat transfer barrel 51 through the cold air outlet 5112 and enters the return air outlet of the air duct assembly 2. During the refrigeration process, the humidity sensor detects the humidity in the storage area in real time. When the humidity in the storage area is lower than the set value, the fan 54 starts, and the fan 54 blows the humid air in the installation area into the storage area, thereby increasing the humidity in the storage area to meet the humidity requirements of the storage items.

[0031] Furthermore, the drawer 52 includes a drawer body 521 and a front panel 522, wherein the front panel 522 is disposed on the drawer body 521 and has an extension portion 5221 for covering the installation area; when the drawer 52 is in a closed state, the front panel 522 simultaneously covers the opening of the storage area and the opening of the installation area. On the one hand, the front panel 522 can realize the requirement of sealed storage of the drawer body 521, and on the other hand, the front panel 522 can also seal and block the installation area without the need to use an additional door panel to close the opening of the installation area. In order to improve the sealing performance of the heat-conducting barrel 51, the barrel opening of the heat-conducting barrel 51 is provided with a sealing ring 513 that cooperates with the front panel 522, and when the drawer 52 is in a closed state, the front panel 522 is abutted against the sealing ring 513. Among them, the heat-conducting barrel 51 can adopt a split structure, and the heat-conducting barrel 51 includes an upper cover plate 512 and a lower shell 511. The upper cover plate 512 is fixed on the lower shell 511. The upper cover plate 512 can be installed on the lower shell 511 by screw fixing, and the humidity sensor 501 is arranged on the upper cover plate 512, and the cold air inlet 5111 and the cold air outlet 5112 are arranged on the lower shell 511.

[0032] Furthermore, the humidification water box 53 includes a box body 531 and a box cover 532, wherein the box cover 532 is detachably mounted on the upper part of the box body 531, and the box cover 532 is provided with a plurality of air holes 5321. Specifically, the box body 531 is used to hold water, and the evaporation of water in the box body 531 keeps the humidity of the installation area at a high humidity level. When the humidity of the storage area needs to be increased, the fan 54 is started, so that the air in the installation area enters the storage area to increase the humidity of the storage area. Preferably, a water level sensor 533 for detecting the water level is also provided in the box body 531. Specifically, the water level in the box body 531 can be detected by the water level sensor 533. When there is not enough water in the box body 531, the user is promptly reminded to replenish the water. The water level sensor 533 can cooperate with the float 5331 for detection.

[0033] By setting a humidifying water box in the heat conduction barrel, the humidifying water box can keep the air humidity in the installation area at a high level. The humidity sensor detects the humidity in the storage area in real time. When the humidity in the storage area is lower than the set value, the fan starts to blow the humid air in the installation area into the storage area, so that the humidity in the storage area rises until the humidity requirement is met, so as to achieve adjustable humidity in the storage area, meet the storage requirements of items with strict humidity requirements, and improve user experience.

Specifically, if the temperature of the freezer compartment 101 is relatively low, the first air outlet 221 on the front cover 21 and the first air return 221 on the rear cover 22 are located in the freezer compartment 101, so that the freezer compartment 101 can always maintain a connected state with the air outlet cavity 220, thereby ensuring sufficient cold supply to meet the freezing requirements, while the second air outlet 212 and the air return 213 are located in the refrigerator compartment 102, and the amount of cold air delivered to the refrigerator compartment 102 is adjusted by switching the first air door 24 in the air supply channel 2201, thereby adjusting the refrigeration temperature in the refrigerator compartment 102. Since the air outlet cavity 220 is used in the air duct assembly 2 to uniformly distribute the cold air, and the air supply channel 2201 and the air return channel 2202 formed in the foam assembly 23 are used to complete the delivery and return of air, the overall structure of the air duct assembly 2 is more compact to meet the miniaturized design, so as to achieve a multi-temperature zone design using air cooling in a small-volume refrigeration device. In order to achieve uniform temperature distribution in the freezer chamber 101, the first air outlet 211 is located above the first return air outlet 221, the air outlet direction of the first air outlet 211 is horizontally set or tilted upward, and the opening direction of the first return air outlet 221 is downward.

At the same time, the first air door 24 is sandwiched between the first foam block 231 and the second foam block 232, so that the first air door 24 is embedded in the foam component 23 to minimize the volume; the first through hole 2311 is connected to the second air outlet 212 and the air supply channel 2201, and the second through hole 2312 is connected to the second return air outlet 213 and the return air channel 2202. Specifically, after the foam component 23 is assembled together by the first foam block 231 and the second foam block 232, an air supply channel 2201 and the return air channel 2202 are formed. According to the needs of air supply and return, corresponding curved grooves can be opened on the surface of the first foam block 231 and / or the second foam block 232. In this way, after the first foam block 231 and the second foam block 232 are assembled, the corresponding grooves form the air supply channel 2201 and the return air channel 2202 to meet the requirements of air supply and return, and at the same time, can better meet the design requirements of miniaturization.
