Air conditioner and its control method

Abstract

The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner and a control method thereof. The invention aims to solve the problem that the outlet direction of the existing snow cover is fixed and cannot be adjusted according to the change of the wind direction, and the snow cover is prone to backflow by wind and snow, which affects the ventilation effect. For this reason, the air conditioner of the present invention comprises an outdoor unit and a control system, the top of the casing of the outdoor unit is provided with an air outlet, and the air conditioner also includes a snow cover communicated with the air outlet, a rotating drive device connected to the snow cover and a set The wind direction detection device on the box body, the snow cover is rotated with the top of the box body, and the rotation drive device and the wind direction detection device are all in communication with the control system. The invention can adjust the outlet direction of the snow cover according to the change of the wind direction, so that the outlet direction and the wind direction can be kept consistent or within a relatively small angle, which can effectively prevent wind and snow backflow and improve ventilation efficiency.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner and a control method thereof. Background technique [0002] The outdoor units of air conditioners generally include top air outlet and side air outlet. For top air outlet air conditioner outdoor units, when it snows in winter, snowflakes will enter the outdoor unit from the air outlet of the top air outlet air conditioner outdoor unit, which is easy to The snow accumulation on the fan and other components, when the snow accumulation reaches a certain level, will hinder the normal operation of the fan, resulting in poor internal air circulation of the outdoor unit of the air conditioner, thereby reducing the working efficiency of the air conditioning system, and may cause damage after the snow melts. security incident. [0003] In the prior art, a fixed snow cover is usually used. Specifically, the snow cover is fixed on the top of the box bod...
