At present, air-cooled refrigerators in the market are controlled by a computer mainboard, and automatic defrosting is carried out through a heater (such as a steel tube heater and a quartz tube heater) fixed on an evaporator. When the frost layer on the evaporator is condensed to a certain thickness, the air-cooled refrigerator enters a defrosting mode, the compressor is stopped, the defrosting heater is electrified to work, and the defrosting mode is exited after the frost on the evaporator is completely removed. Due to the fact that the power of the defrosting heater is large, if the defrosting frequency is too high, the power consumption of the air-cooled refrigerator is too high, and the food fresh keeping is affected. If defrosting is not timely, the evaporator frosts too much, the refrigeration efficiency of the air-cooled refrigerator is affected, and even the air-cooled refrigerator does not refrigerate in severe cases, so that the user experience is affected.

Because the air contains vapor, the vapor can be gradually condensed into frost on the evaporator in the refrigeration process of the air-cooled refrigerator, when the rotating speed of the evaporation fan is fixed, the larger the frost formation amount of the evaporator is, the larger the resistance of the evaporator to air flow is, the smaller the air pressure in the corresponding refrigeration air channel is, and therefore the actual frost formation condition of the evaporator is reflected by the air pressure in the refrigeration air channel. Based on the principle, the invention detects the measured value Ps of the wind pressure in the air duct of the air-cooled refrigerator in real time by arranging the wind pressure sensor in the air duct of the air-cooled refrigeratorPractice ofThe main control module controls the working state of the refrigerating system according to the detection data of the wind pressure sensorAnd in the state, when the measured wind pressure value is less than or equal to the corresponding preset value, the frosting amount of the evaporator is considered to be the maximum, and the air-cooled refrigerator is judged to be in the defrosting mode. The judgment mode is not influenced by factors such as user habits, defrosting can be timely and accurately carried out, energy is saved, environment is protected, the influence of defrosting on the temperature of the compartment is effectively reduced, and the use experience of the air-cooled refrigerator is optimized.
As shown in fig. 1, in a preferred embodiment, the main control module includes a main control board 1, a power supply 2, a defrosting heater 3, a compressor 6, a defrosting temperature sensor 7, a wind pressure sensor 8, etc. are all connected to the main control board 1, the defrosting temperature sensor 7 is used for detecting an actual temperature T on the surface of the evaporator, the defrosting heater 3 provides heat when the evaporator is defrosted, in order to prevent the refrigerator from being affected by an excessively high temperature of the defrosting heater 3, a first temperature fuse 4 is connected in series to one end of the defrosting heater 3, and a second temperature fuse 5 is connected in series to the other end of the defrosting heater 3.
Specifically, the defrosting control method executed by the main control module comprises the following steps:
