As shown in fig. 1 and 2, a control method of an air-cooled refrigerator according to an embodiment is applied to an air-cooled refrigerator including a compressor, a fan, an evaporator, an air duct, a freezing chamber, and a refrigerating chamber, and includes the following steps: when the temperature t of the refrigerating chamber is higher than a first adjusting temperature t1 of the fan, judging whether the fan is in a starting state, if the fan is not in the starting state, controlling the fan to start and controlling the rotating speed of the fan to be a working rotating speed M; controlling the fan to be stopped when a refrigerating compartment temperature t is between a second regulation temperature t2 and a third regulation temperature t3 of the fan and the compressor is in a stop state; controlling the rotation speed of the fan to be a minimum operation rotation speed A when the refrigerating chamber temperature t is between the second regulation temperature t2 and the third regulation temperature t3 and the compressor is in an operation state; when the temperature t of the refrigerating chamber is lower than a third adjusting temperature t3, controlling the fan to stop; the first regulation temperature t1 is higher than the second regulation temperature t2, and the second regulation temperature t2 is higher than the third regulation temperature t 3.
In the control method of the air-cooled refrigerator, when the temperature t of the refrigerating chamber is higher than the first adjusting temperature t1, if the fan is in a stop state, the fan is controlled to start and the rotating speed of the fan is enabled to operate at the working rotating speed M; if the compressor runs, the refrigerating system of the refrigerator runs, the refrigerant in the evaporator of the refrigerator evaporates, cools and cools, and the fan forms cold air produced by the evaporator into cold air to be sent into the refrigerating chamber; if the compressor stops, the fan sends the cold energy of the freezing chamber into the refrigerating chamber in a cold air mode until the temperature t of the refrigerating chamber is lower than a second adjusting temperature t2 of the fan; therefore, the temperature of the refrigerating chamber is effectively and accurately controlled, the requirement of the refrigerating chamber on the temperature is met, and the working cost of refrigeration of the refrigerator is saved. When the temperature t of the refrigerating chamber is lower than the first adjusting temperature t1 and is higher than the second adjusting temperature t2, the temperature t of the refrigerating chamber meets the requirement of the refrigerating chamber for temperature, and the fan does not need to be controlled to be started. When the temperature t of the refrigerating chamber is between the second regulation temperature t2 and the third regulation temperature t3 and the compressor is in a stop state, controlling the fan to stop; when the compressor is in a stop state and the temperature t of the refrigerating chamber is lower than a second adjusting temperature t2, the requirement of the refrigerating chamber on the temperature is met, and the cold energy is not needed any more, so that the fan is controlled to stop, and the refrigerating chamber stops refrigerating; therefore, the temperature of the refrigerating chamber is effectively and accurately controlled, the requirement of the refrigerating chamber on the temperature is met, and the working cost of refrigeration of the refrigerator is saved; when the temperature t of the refrigerating chamber is between the second regulation temperature t2 and the third regulation temperature t3 and the compressor is in the running state, controlling the rotating speed of the fan to be the lowest running rotating speed A; the compressor is in an operating state, which indicates that the fan is in operation and conveys the cooling capacity made by the evaporator to the refrigerating chamber and the freezing chamber, namely the temperature of the freezing chamber does not meet the set requirement yet, and the refrigerating is still needed. When the temperature t of the refrigerating chamber is lower than a third adjusting temperature t3, controlling the fan to stop; the fact that the temperature t of the refrigerating chamber is lower than the third adjusting temperature t3 shows that the temperature t of the refrigerating chamber is already low, the temperature in the refrigerating chamber is not suitable to be reduced continuously, and therefore the fan needs to be controlled to stop to avoid influencing the temperature required by meeting the refrigerating condition. Through the control to the fan for the control of room temperature is more accurate, can avoid moreover because of the refrigerator opens the door, puts into the problem that variables such as high temperature food caused newly, has greatly improved user's result of use. Therefore, the control method of the air-cooled refrigerator not only effectively controls the temperature of the refrigerating chamber and the freezing chamber of the air-cooled refrigerator and ensures the use effect of users, but also saves the working cost of refrigeration of the refrigerator, saves the electric refrigerating air door and reduces the whole cost of the air-cooled refrigerator.

For example, the inner wall of the freezing air duct is provided with an air supply hole and an air duct opening, one end of the air supply hole is communicated with the freezing air duct, and the other end of the air supply hole is communicated with the refrigerating air duct; one end of the air duct opening is communicated with the freezing air duct, and the other end of the air duct opening is communicated with the freezing chamber, so that under the action of the fan, one part of cold air formed in the freezing air duct flows into the freezing chamber, the other part of cold air flows into the refrigerating air duct and enters the refrigerating chamber, and the air supply proportion can be controlled along with the change of the rotating speed of the fan. For example, the evaporator with the fan set up in freezing wind channel deviates from the one end of freezer, just the fan is located the evaporator deviates from the one end of freezer makes things convenient for the fan to act on the cold volume that the evaporator made like this to form cold wind in freezing wind channel, and make cold wind flow more fast towards the freezer direction, shortened cryogenic time, practiced thrift working cost.

Through when the fan moves, detect ambient temperature K and according to ambient temperature K confirms first fan rotational speed X, detects the gear and according second fan rotational speed Y is confirmed to the gear, and control fan rotational speed is operating rotational speed M, operating rotational speed M does first fan rotational speed X with the sum of second fan rotational speed Y has realized the adjustment to the fan rotational speed, has realized the adjustment to walk-in, freezer air supply proportion promptly for the air supply proportion accords with the demand proportion of the walk-in of refrigerator and freezer, has effectively controlled the temperature of the walk-in of air-cooled refrigerator and freezer.
