Embodiment Construction

[0034] 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.

[0035] The refrigerator-freezer also has a refrigeration system configured to provide cooling to the storage compartment. In some embodiments, the refrigeratio...

Abstract

The invention provides a refrigerating and freezing device. The device comprises a storage chamber which is divided into a plurality of storage spaces; each storage space is provided with an air return port; a plurality of air supply outlets are formed in one space wall of each storage space, and the air supply outlets are formed at intervals in the circumferential direction. The device also comprises a cooling chamber, and an air duct device which is provided with an air supply duct for connecting the cooling chamber with the air supply outlets and an air return duct for connecting the air return port with the cooling chamber. The device also comprises a plurality of shielding turntables, each shielding turntable is rotatably mounted at a plurality of air supply outlets of one storage space; each shielding turntable is rotatably arranged around the axis of the corresponding circumferential direction; each shielding rotary disc is provided with a plurality of communicating holes formedin the corresponding circumferential direction at intervals so that at least one of the multiple corresponding air supply outlets can communicate with the corresponding storage space through the corresponding communicating holes or the multiple corresponding air supply outlets can be disconnected from the corresponding storage space when the shielding rotary disc rotates to the preset position. By means of accurate air supply and independent air return, independent adjustable temperature control of different temperature zones of refrigeration is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration 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 only realize the con...
