Air conditioner and control method thereof

Abstract

The invention relates to the technical field of air conditioners, particularly provides an air conditioner and a control method thereof, and aims at solving the problem that condensation is prone to occurring on an air deflector when an existing air conditioner operates in a refrigeration mode. The air conditioner comprises a shell; an air outlet is formed in the shell; an air deflector is arranged at the air outlet; and the air conditioner is further provided with a stepping motor for driving the air deflector to move. The control method of the air conditioner comprises the following steps ofobtaining the current of the stepping motor under the condition that the air deflector swings; comparing the current with a current threshold; and selectively increasing the air outlet speed and / or reducing the frequency of a compressor according to the comparison result. Specifically, the current threshold comprises a first current threshold, and when the current is larger than the first currentthreshold, the air outlet speed is increased, and / or the frequency of the compressor is reduced. Through the control, the evaporation speed of the condensation can be increased or the generation speed of the condensation can be reduced, so that the problem that a large amount of condensation is generated on the air deflector and drips is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and specifically provides an air conditioner and a control method thereof. Background technique [0002] Along with the raising of people's living standard, air conditioner has become the commonly used electric appliance in the vast family. In summer, the cooling operation of the air conditioner lowers the temperature of the user's space and provides a comfortable environment for the user. [0003] However, in summer, the ambient humidity is relatively high. During the cooling operation of the air conditioner, the air outlet of the indoor unit continuously blows out cold air. The temperature continues to drop, and the water vapor in the air is likely to produce a large amount of condensation on the surface of the air deflector after contact with the low-temperature air deflector. When the condensation accumulates to a certain amount, it will drip on the ground and need to be cleaned by ...
