摘要： A control method for a refrigerating and freezing device, and the refrigerating and freezing device are disclosed. The refrigerating and freezing device includes a storage compartment, a refrigeration compartment, and a refrigeration system at least partially arranged in the refrigeration compartment. The control method includes: controlling the refrigeration system to stop supplying cold to the storage compartment; and connecting the refrigeration compartment with the storage compartment, and controlling a fan of the refrigeration system to operate so as to promote air in the refrigeration compartment and the storage compartment to flow circularly. In the present invention, air in the storage compartment is utilized to carry out air defrosting on the refrigeration compartment, and then the defrosted high-humidity gas is led back to the storage compartment; the conceptual limitation of the prior art of utilizing a heating device to generate liquid defrosted water and then carrying out humidification is broken through, and heat of the storage compartment is fully utilized to defrost the refrigeration compartment; and the air temperature after defrosting is more suitable, and more abundant humidity can be brought to the storage compartment, thereby reducing the production cost and energy consumption during use.

摘要： A method for controlling the temperature of a refrigerator, and a refrigerator. A refrigerator (100), comprising a cabinet (110), a thawing chamber (120), a refrigeration system and a micro-air-duct rotary disc (180), wherein a storage compartment is defined by the cabinet (110), and comprises a storage area (112) and a thawing area (Ill), the thawing chamber (120) is arranged in the thawing area (Ill), a refrigeration system is configured to generate cold airflow, and the micro-air-duct rotary disc (180) is configured to make the cold airflow selectively enter the storage area (112) and the thawing chamber (120). In the technical solution, the refrigeration system is started to generate cold airflow when the temperature of the storage area (112) is greater than or equal to a preset storage start-up temperature threshold value, the guiding direction of the cold airflow is determined by means of comparing the temperature of the thawing chamber (120) with a preset thawing shutdown temperature threshold value, and the directional guidance of the cold airflow is completed by means of the micro-air-duct rotary disc (180), thereby meeting different refrigeration requirements of the storage area (112) and the thawing chamber (120); and in the process of controlling the temperature of a compartment, a solenoid valve does not need to be frequently switched, thereby effectively prolonging the service life of the solenoid valve.

摘要： Provided are a control method for a refrigerating and freezing device, and the refrigerating and freezing device. The refrigerating and freezing device includes a cabinet provided with a groove communicating with a surrounding environment and sunken inwards, and at least one fan for promoting air of the surrounding environment to flow into the groove. The control method includes: judging whether a temperature in the groove is less than or equal to a dew point temperature; and if yes, controlling the fan to operate at a first preset rotation speed. In the present invention, the temperature in the groove is increased by controlling the fan to operate to introduce hot air of the surrounding environment into the groove when the temperature in the groove is less than or equal to the dew point temperature, which avoids condensation in the groove and improves safety and reliability of electrical parts in the groove. Compared with an anti-condensation mode of arranging a heating wire or a heat pipe in the groove, the method is low in cost and simple in process, and the production cost is reduced.

摘要： A refrigerator preservation control method and a refrigerator. The refrigerator comprises a box body and a freezer preservation compartment. The box body defines at least one storage compartment. The freezer preservation compartment is arranged in the storage compartment. The refrigerator preservation control method comprises: detecting whether an object to be processed is placed in the freezer preservation compartment; if so, then acquiring the temperature of the object; acquiring a correspondence between preset temperatures of the object and operating modes of the refrigerator; and controlling the refrigerator to operate in accordance with an operating mode corresponding to the temperature of the object. The use of the solution of the present invention may detect the temperature of the object placed in the freezer preservation compartment, and control the refrigerator to operate in accordance with different operating modes according to differences in the temperature of the object, thereby achieving instant preservation.
