Problems solved by technology
When the snow accumulation on the fan blades of the outdoor unit reaches a certain level, the fan starting torque of the outdoor unit of the air conditioner will easily cause the motor of the outdoor unit to burn out, and if the snow accumulation is more severe, the fan blades will be broken
[0003] The main method to solve the snow accumulation on the fan blades in the related technology is to artificially add a snow shelter for the outdoor unit after the outdoor unit is installed, so that the snow flakes cannot be scattered on the fan blades on the top of the outdoor unit.
However, this method increases the cost, and there is uncertainty about whether there is an outdoor installation space for snow shelters, and the appearance of the building after installation is greatly affected

The invention discloses an air conditioning outdoor unit and a control method thereof, and an air conditioner. The control method for the air conditioning outdoor unit comprises the following steps: S1, when an outdoor fan stops operation, detecting outdoor environment temperature T and down time t of the outdoor fan, and comparing the detected outdoor environment temperature T with set temperature a; S2, when T<a, detecting whether the down time of the outdoor fan reaches first preset time T1; when T>=a, continuing to comparing the T with a; S3, when t>=T1, controlling the outdoor fan to operate for second preset time Ta; when t<T1, controlling an indoor fan to keep a stop operation state. According to the control method of the air conditioning outdoor unit, damages of the motor of the outdoor fan caused by too thick snow are prevented, and blades are prevented from being broken by too thick snow. The appearance of the outdoor unit is not changed, so that aesthetics of a building after installation of the air conditioning outdoor unit would not be influenced.
Description
technical field [0001] The invention relates to the refrigeration field, in particular to an air conditioner outdoor unit, a control method thereof, and an air conditioner. Background technique [0002] When the outdoor unit of the air conditioner (top outlet or oblique outlet fan unit) is shutting down, the fan of the outdoor unit stops working. It is especially serious in cold regions such as the north. When the snow accumulation on the fan blades of the outdoor unit reaches a certain level, the fan starting torque of the outdoor unit of the air conditioner will easily cause the motor of the outdoor unit to burn out, and if the snow accumulation is more severe, the fan blades will be broken. [0003] The main method to solve the snow accumulation on the fan blades in the related art is to artificially add a snow shelter for the outdoor unit after the outdoor unit is installed, so that the snow flakes cannot be scattered on the fan blades on the top of the outdoor unit.
