However, when the ambient temperature rises or the humidity is high, if the fan is set to operate at a low speed for dehumidification, not only the condensing pressure will be higher, but also the dehumidification speed will be slower, which will cause the whole machine to stop easily or reduce energy efficiency; when the ambient humidity drops to When it is very low, the dew point temperature is also very low. If the fan runs at high speed, it will cause the evaporation temperature to be higher than the dew point temperature and dehumidification will not be possible, resulting in a decrease in the overall performance of the dehumidifier

The invention discloses a control method for a fan in a dehumidifier. The control method comprises the following steps: obtaining the temperature of a condenser of the dehumidifier; determining a pressure value corresponding to the temperature of the condenser according to the temperature of the condenser; obtaining a pressure difference value between the pressure value and the maximum pressure value of the condenser; and controlling the rotational speed of the fan in the dehumidifier according to the pressure difference value. Through the use of the control method disclosed by the embodiment of the invention, the rotational speed of the fan is controlled through the pressure difference value between a current pressure value of the condenser in the dehumidifier and the maximum pressure value of the condenser; and through the increase, the decrease and the like of the rotational speed of the fan, not only the usage scope of the dehumidifier in a high-temperature and high-humidity environment can be expanded, but also the dehumidifier can effectively remove the humidness under a low-humidity condition, so that a humidness removing effect is improved, the power of the dehumidifier can be lowered, the energy consumption can be reduced, and the whole property of the dehumidifier is improved. The invention further discloses a control device for the fan in the dehumidifier and the dehumidifier with the control device.
Description
technical field [0001] The invention relates to the technical field of living appliances, in particular to a control method and device for a fan in a dehumidifier and a dehumidifier with the control device. Background technique [0002] In the related art, the control method of the dehumidifier is generally: in the continuous dehumidification mode, it operates at the set fan speed under the general operating environment. However, when the ambient temperature rises or the humidity is high, if the fan is set to operate at a low speed for dehumidification, not only the condensing pressure will be higher, but also the dehumidification speed will be slower, which will cause the whole machine to stop easily or reduce energy efficiency; when the ambient humidity drops to When it is very low, the dew point temperature is also very low. If the fan runs at a high speed, it will cause the evaporation temperature to be higher than the dew point temperature and dehumidification will not ...
