One air supply opening is arranged at the transverse middle part of the upper part of the first storage space 211, and the air supply opening is communicated with the middle first storage space 211 and the lowest first storage space 211. One air supply opening communicated with the second storage space 212 is arranged at one lateral side of the upper part of the second storage space 212, and the communicated first air return opening 81 is arranged at the other lateral side of the lower part of the second storage space.
Return air ducts are arranged in the first return air assembly 85 and the second return air assembly 86, and each first return air opening 81 is communicated with the corresponding return air duct. The return air duct has a main return air inlet 83 communicating with the cooling chamber. The air supply assembly 70 also has an air inlet which can be communicated with the cooling chamber via an air inlet pipeline, and the outlet of the cooling chamber can be provided with a fan 28 for promoting the air flow.
In the first return air assembly 85: the area ratio between the uppermost first air return port 81 and the first air return port 81 therebelow is 2 to 3; of the middle two first air returns 81, the area ratio between the lower first air return 81 and the upper first air return 81 is 1/2 to 7/10; the area ratio between the lowermost first air return opening 81 and the first air return opening 81 on the upper side thereof is 5 to 10. For the convenience of control, a plurality of temperature sensors 51 are further disposed in the air supply assembly 70 to detect the temperature in each storage space 21, so that the refrigerating and freezing device can be controlled according to the temperature detected by the temperature sensors 51. Each temperature sensor 51 can sense a temperature change of the corresponding storage space 21.
In the embodiment of the present invention, as shown in fig. 4 to fig. 6, the air conditioning delivered from the cooling chamber reaches the air supply assembly 70, and the air volume distributor is installed in the air supply assembly 70, i.e. the on-off control device 60, and the distributor realizes independent air supply or combined arbitrary air supply to each partition air path, reaches each partition, returns air through the independent air return opening of each partition, and then converges to the corresponding return air duct assembly inside and returns to the cooling chamber together. The rack 40 and the inner container of the box 20 form a seal therebetween, so as to prevent the temperature fluctuation and control of the next layer from being affected by the sinking of cold air. The display control board is provided with 2 ℃, 5 ℃ and 10 ℃ selection buttons (or low, medium and high) for gear selection, and information display of storage types is displayed to remind a user of what articles are placed in what area. When air needs to be supplied to any one of the storage spaces 21, the air flows out through the corresponding air supply opening, passes through the rack 40 and reaches the bottle seat 31 and the first door 30, and due to the arrangement of the first air return opening 81, the air is returned to return through the air return opening communicated with the corresponding storage space 21, so that a refrigeration cycle is completed. When the temperature of the temperature sensor 51 corresponding to each partition reaches the set temperature, the corresponding air outlet 63 on the on-off control device 60 is closed to stop air supply. The rack 40 and the bottle seat 31 have the same temperature. One part of the air in the storage space 21 at the lowest side can reach the bottle seat 31 and the first door body 30 through the rack 40, the other part can move downwards to the drawer area to convey cold, the cold proportioning of each subarea is controlled through the difference of the sizes of the air return openings, and the balance of the set temperature is achieved. The temperature sensor 51 detects that the temperature of the storage space 21 is higher than the temperature of the air to be supplied, and the distributor supplies air to the section. An independent air return opening is arranged in each storage space 21, the size of each air return opening is strictly calculated and simulated and analyzed, factors such as heat conduction and refrigerating capacity are considered, and the area ratio of the four first air return openings 81 from top to bottom in the first air return assembly 85 is preferably 6:2.5:1.5: 10.
The refrigeration and freezing device of the embodiment of the utility model can realize multi-partition temperature control of the refrigeration chamber; each partition can realize three-gear temperature change; the user selects the temperature interval according to the needs; the size ratio of the air return opening is strictly calculated to achieve the temperature balance. The arrangement structure mode of the air return inlet; the air return opening, the rack 40 and the bottle seat 31 are mutually matched to realize the air path circulation mode of temperature change adjustment and humidity adjustment of the refrigerating and freezing device. Each display control panel can be arranged on the side wall of each storage space 21 and close to the position of the first door body 30, so that the operation is convenient. The user can adjust the device freely according to own habits, and the device is convenient for the user to use. And can guide the user to correctly place the food for storage, reduce extravagantly. Foods that were previously dare to be put in the refrigerator can also be put in the refrigerator to prolong the shelf life. The food can be stored in the optimal temperature and humidity environment, and the freshness can be greatly improved. Air is supplied when each subarea needs air supply, so that food is prevented from being overcooled, and energy is saved.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
