Problems solved by technology

[0003] The fan in the refrigerator is generally installed close to the evaporator, and the temperature near the evaporator is relatively low. If the damper is not closed, there will be convection of hot and cold air, so it is easy to generate frost on the fan
Since the fan cannot automatically frost, when the fan starts to run again, the presence of frost on the fan will seriously affect the fan speed, resulting in a small air volume and reducing the cooling effect

Abstract

The invention provides a refrigerator and a control method of the refrigerator. The refrigerator comprises a storage compartment, a refrigeration system for providing cold quantity for the storage compartment, a draught fan conveying the cold quantity to the storage compartment and a control system for controlling the refrigerator to run; the refrigeration system and the draught fan are both electrically connected with the control system, and the refrigerator further comprises a rotating speed sensor which is arranged on the draught fan and used for measuring the rotating speed of the draught fan; the rotating speed sensor and the control system are electrically connected, and a preset threshold value used for being compared with the rotating speed of the draught fan is set in the control system; and the rotating speed measured through the rotating speed sensor is compared with the threshold value so as to judge the frosting condition on the draught fan, and comparison is accurate and intuitive.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator capable of automatically removing frost on a fan and a control method thereof. Background technique [0002] In existing refrigerators, especially refrigerators with manual air doors, when the temperature in the storage room of the refrigerator is lower than the set minimum temperature, the refrigeration system and the fan will automatically stop running, but the air door will not be automatically closed. [0003] The fan in the refrigerator is generally installed close to the evaporator, and the temperature near the evaporator is relatively low. If the damper is not closed, there will be convection of cold and hot air, so it is easy to generate frost on the fan. Since the fan cannot automatically defrost, when the fan starts to operate again, the presence of frost on the fan will seriously affect the rotation speed of the fan, resulting in a small air volume a...
