[0034] Next, the embodiments of this specification will be described in detail.

[0035] As Figure 1 and Figure 3 shown, the cold storage device of this application includes a first variable temperature chamber 1, a storage chamber 2, and a second variable temperature chamber 3. The storage chamber 2 includes a first storage space 21 and a storage chamber door body 22. The second variable temperature chamber 3 is provided on the storage chamber door body 22, and the second variable temperature chamber 3 communicates with the first variable temperature chamber 1.

[0036] By providing the second variable temperature chamber 3, the variable temperature storage space can be increased. And the first variable temperature chamber 1 and the second variable temperature chamber 3 can independently adjust the storage temperature respectively to store more items with different requirements for the storage temperature. At the same time, the second variable temperature chamber 3 is separately provided from the first variable temperature chamber 1, and items can be stored separately in the second variable temperature chamber 3 to improve the privacy of item storage. The first variable temperature chamber 1 communicates with the second variable temperature chamber 3, which can reduce the usage amount of pipelines and lower the manufacturing cost.

[0037] In one embodiment, in the height direction of the cold storage device, the first variable temperature chamber 1 is located below the storage chamber 2. The first variable temperature chamber 1 includes an air outlet 11, a first air inlet 12, and a second air inlet 13. The gas in the first variable temperature chamber 1 circulates through the air outlet 11 and the first air inlet 12 to ensure the cleanliness of the gas in the first variable temperature chamber 1. The gas in the second variable temperature chamber 3 enters the first variable temperature chamber 1 through the second air inlet 13 to participate in the gas circulation.

[0038] In one embodiment, the storage chamber 2 is preferably a refrigerating chamber. The second variable temperature chamber 3 is provided in the storage chamber 2. Since the storage temperature in the second variable temperature chamber 3 is close to the temperature in the storage chamber 2, the stability of the temperature in the second variable temperature chamber 3 and the storage chamber 2 can be effectively maintained. At the same time, it also avoids the problems of temperature imbalance and increased energy consumption caused by too large a difference in the internal storage temperatures of the two.

[0039] In another embodiment, the cold storage device includes a freezer 7, and the freezer 7 includes a freezing space 71 and a freezer door body 72. Under the condition of good heat preservation work, the second variable temperature chamber 3 can also be provided on the freezer door body 72. And when the freezer door body 72 closes the freezing space 71, at least part of the second variable temperature chamber 3 extends into the freezing space 71. It should be noted that the second variable temperature chamber 3 can also be provided on the door body of the first variable temperature chamber 1.

[0040] Further combined Figure 4 and Figure 5 As shown, in one embodiment, the storage chamber door body 22 is used to open and close the first storage space 21. The second variable temperature chamber 3 is provided on the inner side of the storage chamber door body 22, and when the storage chamber door body 22 closes the first storage space 21, at least part of the second variable temperature chamber 3 extends into the first storage space 21. Such a setting avoids the excessive thickness of the storage chamber door body 22, and at the same time ensures that the volume of the second variable temperature chamber 3 can store more items.

[0041] The housing of the second variable temperature chamber 3 is provided with heat insulation materials to prevent the storage temperature in the second variable temperature chamber 3 from affecting the storage temperature in the storage chamber 2, thereby affecting the storage quality of the items.

[0042] In one embodiment, the temperature in the second variable temperature chamber 3 is not less than -5°C and not greater than 5°C. Since the second variable temperature chamber 3 is a newly established variable temperature storage space, it can store items targeted and ensure the privacy of the items. The storage temperature in the second variable temperature chamber 3 is preferably between -5°C and 5°C to meet the storage requirements of most items.

[0043] The temperature adjustment range of -5°C to 5°C can prevent the items from freezing and over-freezing due to low temperature, and can also prevent the items from being damaged due to high temperature, and can also save energy and reduce the cost of use. Of course, for items with special requirements for storage temperature, the storage temperature in the second variable temperature chamber 3 can also be adjusted between -7°C and 7°C.

[0044] In one embodiment, the second variable temperature chamber 3 includes a second storage space 31, a variable temperature chamber door 32, and a variable temperature chamber housing 36. The variable temperature chamber door 32 is disposed on the variable temperature chamber housing 36 to open and close the second storage space 31. Specifically, when the variable temperature chamber door 32 closes the second storage space 31, the variable temperature chamber door 32 is closely attached to the variable temperature chamber housing 36 to avoid the storage temperature in the second variable temperature chamber 3 and the storage temperature in the storage chamber 2 from affecting each other due to a gap between the two.

[0045] In the height direction of the cold storage equipment, the opening and closing direction of the variable temperature room door 32 is opposite to the opening and closing direction of the storage room door 22. Specifically, the storage room door 22 is arranged on the right side of the storage room 2. When the storage room door 22 is open, the variable temperature room door 32 is located on the left side of the second variable temperature room 3. In the height direction of the cold storage equipment, the variable temperature room door 32 opens counterclockwise and closes clockwise, while the storage room door 22 opens clockwise and closes counterclockwise. For details, please refer to Figure 1 With such arrangement, the temperature-changing room door 32 can rotate toward the first storage space 21 when opened, thereby avoiding interference with the placement space of the cold storage device and improving the convenience of using the cold storage device.

[0046] In another embodiment, the opening and closing direction of the variable temperature chamber door 32 is set to be the same as the opening and closing direction of the storage chamber door 22. Specifically, the storage chamber door 22 is set on the right side of the storage chamber 2. When the storage chamber door 22 is open, the variable temperature chamber door 32 is on the right side of the second variable temperature chamber 3. In the height direction of the cold storage equipment, the variable temperature chamber door 32 opens counterclockwise and closes clockwise, while the storage chamber door 22 also opens counterclockwise and closes clockwise. For details, please refer to Figure 2 Such arrangement enables the storage chamber door 22 to rotate away from the first storage space 21 when opened, and even when the storage chamber door 22 is opened at a small angle, the temperature-changing chamber door 32 can be opened, making it convenient to take and put items.

[0047] Further integration Figures 6 to 8As shown, in one embodiment, the second temperature-changing chamber 3 includes a temperature control device 33. The temperature control device 33 is arranged on the inner wall of the temperature-changing chamber housing 36 and is located in the second storage space 31. The temperature control device 33 is used to control the temperature in the second temperature-changing chamber 3 so that the temperature in the second temperature-changing chamber 3 is between -7°C and 7°C, thereby increasing the storage time of the items.

[0048] In one embodiment, the air entering the second temperature-changing chamber 3 first flows through the temperature control device 33, and then flows from the temperature control device 33 into the second storage space 31. A heating element (not shown) is provided in the temperature control device 33, and the heating amount of the heating element is controlled by adjusting the power and the opening time of the heating element, thereby controlling the temperature of the gas entering the second temperature-changing chamber 3.

[0049] Specifically, the cold storage device includes a temperature sensor (not shown) and a processor (not shown). The temperature sensor is located in the second storage space 31 and is used to sense the temperature in the second storage space 31. The temperature sensor is electrically connected to the processor, and the temperature sensor can feed back the temperature information in the second storage space 31 to the processor. The temperature control device 33 is electrically connected to the processor, and the processor is used to receive the temperature information fed back by the temperature sensor to control the start and stop of the temperature control device 33.

[0050] The temperature control device 33 is provided with a plurality of temperature control air outlets 331 , so that the gas flowing out of the temperature control device 33 can be quickly distributed into the second storage space 31 .

[0051] In one embodiment, the second temperature-changing chamber 3 includes a mounting member 34 and a storage member 35. The mounting member 34 and the storage member 35 are both located in the second storage space 31. Specifically, the mounting member 34 is disposed on the inner wall of the temperature-changing chamber housing 36, and the storage member 35 is disposed on the mounting member 34. The storage member 35 is used to hold items. The storage member 35 can divide the second storage space 31 into a plurality of smaller storage spaces, thereby improving the utilization rate of the second storage space 31 and storing more items.

[0052] In one embodiment, to facilitate the storage of articles, the storage member 35 is detachably arranged on the mounting member 34. Indeed, to ensure the firmness of the storage member 35, the storage member 35 can be fixedly installed on the mounting member 34.

[0053] Further integration Figure 9 As shown, the mounting member 34 includes a first stopper 341, a second stopper 342 and a third stopper 343. The storage member 35 includes a partition 351 and a receiving drawer 352. The first stopper 341 and the second stopper 342 are both present in pairs and are respectively located on the opposite side walls of the variable temperature room housing 36. In the front-to-back direction of the cold storage device, the first stopper 341 is located in front of the second stopper 342. The second stopper 342 is arranged in a C shape, and the opening of the second stopper 342 faces the first stopper 341.

[0054] When the partition 351 is installed, the partition 351 abuts against the first stopper 341 and is located above the first stopper 341. At the same time, the partition 351 is engaged with the second stopper 342. The partition 351 can move in the front-back direction of the cold storage device to achieve installation and disassembly. When the accommodation drawer 352 is installed, the accommodation drawer 352 contacts the bottom of the second storage space 31 and abuts against the third stopper 343.

[0055] In one embodiment, if there are many small-sized items to be stored, in order to meet the storage requirements, a plurality of partitions 351 can be provided in the second storage space 31. If there are large-sized items to be stored, they can be placed in the accommodation drawer 352 and the partition 351 can be disassembled.

[0056] In one embodiment, the second variable temperature chamber 3 includes a lock body 37. The lock body 37 is respectively provided on the variable temperature chamber door body 32 and the variable temperature chamber housing 36. The variable temperature chamber door body 32 is locked to the variable temperature chamber housing 36 through the lock body 37 to ensure that the variable temperature chamber door body 32 closely fits the variable temperature chamber housing 36, prevent the temperatures in the second variable temperature chamber 3 and the storage chamber 2 from affecting each other, and at the same time ensure the privacy when storing items.

[0057] In one embodiment, the cold storage device includes a supply air duct 4 and a return air duct 5. The supply air duct 4 is respectively communicated with the first variable temperature chamber 1 and the second variable temperature chamber 3, and the return air duct 5 is also respectively communicated with the first variable temperature chamber 1 and the second variable temperature chamber 3. Specifically, one end of the return air duct 5 is communicated with the second air inlet 13, and the other end of the return air duct 5 is communicated with the second variable temperature chamber 3. The gas in the second variable temperature chamber 3 can flow into the first variable temperature chamber 1 through the return air duct 5.

[0058] The supply air duct 4 includes an air outlet end 41, and the air outlet end 41 is connected to the temperature control device 33. The return air duct 5 includes an air inlet end 51, and the air inlet end 51 is connected to the second variable temperature chamber 3. Both the air outlet end 41 and the air inlet end 51 are flexible structures, for example, they can be corrugated pipes, rubber pipes, etc. Such a setting prevents the air outlet end 41 and the air inlet end 51 from being easily damaged due to repeated folding when the storage chamber door body 22 is opened and closed and drives the third variable temperature chamber 3 to rotate, thereby improving the service life of the supply air duct 4 and the return air duct 5 and reducing the failure rate of the cold storage device.

[0059] In one embodiment, the cold storage device includes a refrigeration component 6. The refrigeration component 6 is provided on the first variable temperature chamber 1 and is communicated with the supply air duct 4. The cold air generated by the refrigeration component 6 can be blown into the second variable temperature chamber 3 through the supply air duct 4. The refrigeration component 6 is respectively communicated with the air outlet 11 and the first air inlet 12. The cold air generated by the refrigeration component 6 can also be blown into the first variable temperature chamber 1 through the air outlet 11, and the gas in the first variable temperature chamber 1 enters the refrigeration component 6 through the first air inlet 12. In this way, the gas in the first variable temperature chamber 1 is circulated.

[0060] The cold storage device of the present application can be a refrigerator, a freezer or a cold storage.

[0061] By providing the first variable temperature chamber 1 and the second variable temperature chamber 3, the cold storage device of the present application increases the size of the overall variable temperature storage space to store more items. At the same time, the second variable temperature chamber 3 is provided on the storage chamber door body 22, so that the second variable temperature chamber 3 is independently provided from the first variable temperature chamber 1 and can store items separately, improving the privacy of item storage. Moreover, the first variable temperature chamber 1 and the second variable temperature chamber 3 can independently adjust the storage temperature to meet different storage temperature requirements and increase the types of items stored. Through the above settings, the user experience of the cold storage device can be improved and the market competitiveness can be enhanced.
