Refrigerator and control method thereof

Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigerating chamber, a freezing chamber, a first varying temperature chamber arranged independent of the refrigerating chamber and the freezing chamber, at least one second varying temperature chamber contained in the refrigerating chamber, a refrigerating chamber air supply air channel formed behind the refrigerating chamber, a refrigerating fan, a refrigerating chamber air door, second varying temperature chamber air doors, a control unit used for receiving temperature information fed back by a refrigerating chamber temperature sensor and / or a second varying temperature chamber temperature sensor and selectively controlling the refrigerating chamber air door and / or the second varying temperature chamber air doors to be opened or closed, and a refrigerating unit used for receiving the temperature information fed back by the refrigerating chamber temperature sensor and selectively controlling a refrigerating evaporator to connect or disconnect a refrigerant loop. Compared with the prior art, the refrigerator enables temperature in the temperature area of the varying temperature chambers located in the refrigerating chamber to reach minus 7 DEG C and even lower while ensuring that temperature of the refrigerating chamber will not be too low. Meanwhile, the refrigerator has the effects of saving energy, reducing noise and prolonging the service life.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigerator with three systems and five temperature zones and a control method thereof. Background technique [0002] With the continuous improvement of people's living standards, the quality requirements for household appliances are also getting higher and higher. In order to realize multiple functions such as refrigeration, freshness preservation, freezing temperature and freezing that span the refrigeration and freezing temperature zones, it is necessary to set up a variable temperature room. At present, most of the existing schemes to realize the refrigerator with three systems and five temperature zones are to add two more variable temperature zones in the refrigerator room, but considering the temperature range of the refrigerator room, the minimum temperature range of the newly added two variable temperature zones can only be To above 0°C, compared with the variable room that i...

At present, most of the existing schemes to realize the refrigerator with three systems and five temperature zones are to add two more variable temperature zones in the refrigerator room, but considering the temperature range of the refrigerator room, the minimum temperature range of the newly added two variable temperature zones can only be To above 0°C, compared with the variable temperature room set independently of the refrigerator and freezer, its temperature range is narrow, which cannot meet the user's needs for low temperature such as soft freezing and freezing
