Embodiment Construction

[0043] figure 1 is a schematic front view of a refrigerator-freezer according to an embodiment of the present invention. Such as figure 1 shown, and refer to Figure 2 to Figure 6 , the embodiment of the present invention provides a refrigeration and freezing device. The refrigerating and freezing device includes a box body 20 , and a storage compartment is defined in the box body 20 . The refrigerator-freezer also has a door body for opening and closing the storage compartment. Wherein, the storage compartment may be a refrigerated compartment. A freezer compartment 22 and a variable temperature compartment can also be set in the casing 20 . Further, the temperature within the freezer compartment 22 generally ranges from -22°C to -14°C. The variable temperature chamber can be adjusted to -18°C to 8°C at will.

[0044]The refrigerator-freezer also has a refrigeration system configured to provide cooling to the storage compartment. In some embodiments, the refrigeration...

Abstract

The invention provides a control method for a refrigerating and freezing device. Including: obtaining the information of the storage space where the item is placed, and obtaining the storage space to be controlled; judging whether the first temperature control information for controlling the storage space to be controlled is received, and if it is controlled according to the first temperature Information control corresponding to the opening and closing device to control the storage space to be controlled; otherwise, obtain information on items placed in the storage space to be controlled to obtain item information; control the corresponding storage space according to the item information The opening and closing device is used to control the storage space to be controlled. Through precise air supply and independent air return, the independent and adjustable temperature of different temperature zones of the refrigerator can be realized. And according to the type of items put in, the temperature of the corresponding storage partition can be adjusted artificially or automatically, so that the food can be stored at the best storage temperature, so that each partition of the refrigerator can achieve the best fresh-keeping effect.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a control method for a refrigerating and freezing device. Background technique [0002] With the development of social economy and the improvement of people's living standards, refrigerators have also become an indispensable household appliance in people's daily life. Existing refrigerator refrigerated compartments are uniformly controlled in temperature, each of which is set at a uniform temperature of 0-5°C, and the optimum storage temperature for all foods is different. If the user sets the temperature to the low range of 0°C, the temperature of the entire compartment of the refrigerator will be around 0°C. Food stored at an optimal temperature greater than 5°C will greatly shorten the food preservation period and accelerate food deterioration. That is, the air duct of the existing air-cooled refrigerator supplies air to the entire refrigerating room, and can...
