Embodiment Construction
[0056] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0057] Apparently, the illustrated embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
[0058] In order to facilitate understanding, in the present invention, it is necessary to elaborate on the technical problems therein.
[0059] The outdoor unit of the top air conditioner is often installed on the roof or outdoors in the open air. After the outdoor unit stops running for a long time in winter, it is easy to accumulate a large amount of snow on the top of the outdoor unit and even on the fan due to snowfall. Once snow a...

The invention provides an air conditioner snow accumulation prevention method and device and an air conditioner. The method comprises the steps that after the air conditioner is powered on, and the outdoor environment temperature is obtained; whether the air conditioner meets snow accumulation risk conditions or not is judged according to the outdoor environment temperature; if the air conditionermeets snow accumulation risk condition, the current of an air conditioner outdoor fan motor is obtained; whether the air conditioner meets the snow accumulation condition or not is judged according to the outdoor fan motor current and preset limit current; and if the air conditioner meets snow accumulation condition, a first snow removal operation is executed. In this way, the snow accumulation condition of the air conditioner outdoor unit can be judged directly through the current of the outdoor fan motor, so that snow is directly removed after snow accumulation; by means of the method, theproblem that accumulated snow increases resistance when the air conditioner is started can be avoided, and the problem that accumulated snow causes poor heat exchange of the outdoor unit when the airconditioner operates normally can be avoided, and therefore it is guaranteed that the energy efficiency ratio of the air conditioner is not reduced due to the accumulated snow, and energy consumptionof the air conditioner is not increased due to the accumulated snow.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner snow prevention method, device and air conditioner. Background technique [0002] The outdoor unit of the top air conditioner is often installed on the roof or outdoors in the open air. After the outdoor unit stops running for a long time in winter, it is easy to accumulate a large amount of snow on the top of the outdoor unit and even on the fan due to snowfall. Once snow accumulation occurs, it will not only increase the resistance when starting, but also cause poor heat exchange of the external unit during normal operation of the air conditioner, reduce the energy efficiency ratio of the air conditioner, and increase the energy consumption of the air conditioner in disguise. [0003] Therefore, anti-snow accumulation of air conditioners has become a common configuration of air conditioners in snowfall areas. However, the existing snow prevention me...
