And the temperature-controllable plate 700 is arranged at the cold air port 231 and is configured to be controlled to translate so as to open and close a communication surface between the cold air port 231 and the air supply duct 112.
Offer cold wind mouth 231 at the back of storing container 200, and set up controllable temperature regulation board 700 in cold wind mouth 231 department, utilize the controlled translation of controllable temperature regulation board 700 to adjust the area of intercommunication between cold wind mouth 231 and the air supply wind channel 112, when controllable temperature regulation board 700 opens cold wind mouth 231, cold wind mouth 231 is in open state, the area of intercommunication between cold wind mouth 231 and the air supply wind channel 112 is the biggest, low temperature air current in the air supply wind channel 112 can get into storing container 200 through cold wind mouth 231 in, thereby make the temperature in the storing container 200 reduce fast, be favorable to making to form the low temperature fresh-keeping environment in the storing container 200 rapidly, the fresh-keeping ability of storing container 200 has been improved.
The temperature sensor 240 is disposed in the storage container 200 and configured to detect a temperature in the storage container 200 after the storage container 200 is closed.
The temperature-controllable temperature-adjusting plate 700 is configured to open the cold air port 231 when the temperature in the storage container 200 is higher than a first preset temperature threshold value, so as to rapidly reduce the temperature in the storage container 200; the temperature-controllable plate 700 is further configured to shield the cold air port 231 when the temperature in the storage container 200 falls below a second preset temperature threshold; the first preset temperature threshold is greater than the second preset temperature threshold.
After the storage container 200 is opened, gas exchange will occur with air in the external environment, resulting in temperature rise and oxygen concentration rise inside the storage container 200, and therefore, after the storage container 200 is closed, it is generally necessary to determine whether rapid cooling of the storage container 200 and oxygen removal for the storage container 200 are required according to the actual storage environment temperature and the actual oxygen concentration, so as to create a low-temperature fresh-keeping atmosphere again. In this embodiment, after the storage container 200 is closed, it is determined whether the storage container 200 is rapidly cooled, and when the temperature in the storage container 200 is within the preset fresh-keeping temperature range, it is determined whether the storage container 200 is deaerated.
That is, when storing container 200 has cooling demand and deoxidization demand simultaneously, utilize controllable temperature adjusting plate 700 to open cold wind mouth 231 earlier and come rapid cooling, after storing container 200 reached predetermined fresh-keeping temperature range, controllable temperature adjusting plate 700 of control shields cold wind mouth 231 and makes storing container 200 form confined storing environment, then open deoxidization subassembly 320 to storing container 200 internal environment deoxidization again, can make the fresh-keeping environment of quick formation low temperature hypoxemia in the storing container 200, the refrigerator 10 of this embodiment can be applicable to and deposit alone of the material or the medicine that require very harsh to storing environment.
When the temperature in the storage container 200 is higher than the first preset temperature threshold, which means that the actual storage environment temperature in the storage container 200 is higher at this time, the controllable temperature-adjusting plate 700 needs to be controlled to open the cold air port 231, so that the communication area between the air supply duct 112 and the cold air port 231 is increased (the cold air port 231 is completely opened), and air supply flow can directly enter the storage container 200, so that the temperature in the storage container 200 is rapidly reduced, and a low-temperature fresh-keeping environment is formed again; when the temperature in the storage container 200 drops below the second preset temperature threshold value, it means that the actual storage environment temperature in the storage container 200 at this moment has dropped to the preset fresh-keeping temperature range, the controllable temperature-adjusting plate 700 is controlled to shield the cold air inlet 231 at this moment, so that the cold air inlet 231 is in a closed state, the communication area between the cold air inlet 231 and the air supply duct 112 is minimum (the communication area at this moment is zero), so that a closed low-temperature storage environment is formed in the storage container 200, and the independent storage of food materials is facilitated.
