Refrigerator and control method thereof

Abstract

The invention provides a refrigerator and a control method thereof. The refrigerator comprises a refrigeration chamber, a refrigeration system, an air channel, a fan, an air door and a controller, wherein the refrigeration system provides cold energy for the refrigeration chamber, the air channel and the fan conveys the cold energy generated by the refrigeration system into the refrigeration chamber, and the air door is arranged at the part, close to the refrigeration chamber, of the air channel. The refrigeration system comprises a compressor, a condenser, a throttling device and an evaporator, wherein the compressor, the condenser, the throttling device and the evaporator are sequentially connected. The refrigeration chamber has a cold storage mode and a freezing mode. The refrigerator further comprises a regenerator, a first temperature sensor and a second temperature sensor, wherein the regenerator is arranged close to the evaporator or located in the air channel, the first temperature sensor is used for sensing the temperature of the regenerator and the second temperature sensor is arranged in the refrigeration chamber and used for sensing the temperature of the refrigeration chamber. When the refrigeration chamber is in the cold storage mode, the process that the compressor is started to provide the cold energy for the regenerator and the process that the regenerator provides the cold energy for the refrigeration chamber are carried out alternately, and therefore the beneficial effect of preserving freshness and protecting food against frost damage can be realized.

Description

technical field [0001] The invention relates to the field of refrigerating equipment, in particular to a refrigerator with a cool accumulator capable of switching between a refrigerating mode and a freezing mode and a control method thereof. Background technique [0002] Refrigerator is one of the essential household appliances in many families, which provides convenience for people's life. With the development of refrigerator technology and the diversification of consumer demand, there have been refrigerators that can switch between refrigeration mode and freezing mode. to meet the needs of consumers. [0003] Existing refrigerators that can switch between the refrigeration mode and the freezing mode, after the self-freezing mode is converted to the refrigeration mode, when the refrigeration system is started to provide cooling capacity to the refrigeration compartment, the cold air is originally used in the freezing mode. The air outlet blows directly onto the food, and t...

Problems solved by technology

[0003] Existing refrigerators that can switch between the refrigeration mode and the freezing mode, after switching from the freezing mode to the refrigeration mode, when the refrigeration system is started to provide cooling capacity to the refrigeration compartment, the cold air will be used in the freezing mode. The air outlet blows directly onto the food, and the cold air at this time is generally below -20°C, which is easy to frostbite the food
