Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The invention provides a snow accumulation judging device, which is installed on an air conditioner outdoor unit, and is used for judging whether there is snow accumulation on the air conditioner outdoor unit, and judging the size of the snow accumulation, that is, the degree of snow accumulation. The outdoor unit of the air conditioner controls the operation of the outdoor fan by using the snow accumulation degree obtained by the snow accumulation judging device, so as to clear the snow accumulation on the external unit of the air conditioner.

[0040] Such as figure 1 As shown, the snow accumulation judging device includes:

[0041] The snow collector 110 collects the snow falling on the outdoor unit of the air conditioner, and the snow collector is provided with an outlet;

[0042] The heating module 120 i...

Abstract

The invention discloses an accumulated snow judging device which is installed on an air conditioner outdoor unit. The accumulated snow judging device comprises an accumulated snow collector which collects accumulated snow fallen on the air conditioner outdoor unit and is provided with an outlet, a heating module which is used for heating the accumulated snow collector when accumulated snow exists on the air conditioner outdoor unit, and a flow detecting module which is installed at the outlet of the accumulated snow collector and used for detecting the flow value of liquid flowing out of the outlet and judging the snow accumulation degree according to the flow value. The invention further discloses the air conditioner outdoor unit and a snow removal control method. Not only can whether accumulated snow exists or not be judged, but also the snow accumulation degree on the air conditioner outdoor unit can be judged. In addition, through the snow accumulation degree judged by the accumulated snow judging device, an outdoor fan is controlled to run at different rotating speeds so that the outdoor fan can remove accumulated snow on the air conditioner outdoor unit, and therefore the energy wasted for snow removal conducted when no snow exists is avoided, and the snow removal efficiency is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a snow accumulation judging device, an air conditioner external unit and a snow removal control method. Background technique [0002] The outdoor unit of the air conditioner is generally installed on the outside, especially for the outdoor unit of the air conditioner with air vents on the top. When it is snowing, the snow on the outer unit of the air conditioner will affect the performance of the air conditioner and the reliability of the parts, and even cause the outdoor unit to be damaged. stop running. And the existing snow removal method is to control the outdoor fan to run for a period of time when the outdoor temperature is less than 0°C. However, this method cannot accurately judge the snow accumulation situation, and there is a possibility of snow removal without snow. Contents of the invention [0003] The main purpose of the present invention is to provide a snow acc...
