Problems solved by technology

[0003] However, the above method for controlling the speed of the fan motor does not make good use of the speed of the fan motor to balance the temperature changes in the box, and does not take into account the difference in the speed of the fan motor at different compressor speeds, for example, at high compressor speeds , has been using a large fan motor speed to send to the refrigeration and variable temperature room, which leads to a waste of part of the cooling capacity of the compressor

Abstract

The invention discloses a fan motor control method and a fan motor control device for a refrigerator and the refrigerator, wherein the refrigerator comprises a compressor, an air door of a refrigerating chamber and an air door of a temperature varying chamber. The fan motor control method comprises the following steps: obtaining an environment temperature of the refrigerator and current rotation speed of a compressor; determining an environment temperature state of the refrigerator according to the environment temperature; determining the voltage of a fan motor according to the environment temperature and the current rotation speed of the compressor. According to the fan motor control method of the refrigerator disclosed by the embodiment of the invention, the voltage of the fan motor is determined according to the environment temperature state and the current rotation speed of the compressor, so that the rotation speed of the fan motor is determined, the cooling speed is improved, the on-off time is optimized, an energy-saving effect is achieved, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a method and device for controlling a fan motor of a refrigerator and the refrigerator. Background technique [0002] Refrigerators in the related art generally adopt a control method for the speed of the fan motor: low speed under normal conditions, and high speed under the following conditions: 1. High speed 10s before the compressor is turned on; 2. When the ambient temperature is higher than 35°C 3. It is high speed in special mode, such as quick cooling, quick freezing, etc. [0003] However, the above method for controlling the speed of the fan motor does not make good use of the speed of the fan motor to balance the temperature changes in the box, and does not take into account the difference in the speed of the fan motor at different compressor speeds, for example, at high compressor speeds , has been using a large fan motor speed to send to the cold storag...
