Abstract

The invention provides an accumulated snow detection device and method and an air conditioner system. The accumulated snow detection device comprises a weight sensing device, a heating device and a body part. The weight sensing device comprises a collection inclined plane, the horizontal plane and the collection inclined plane form a preset angle, and the weight sensing device senses the weight on the collection inclined plane. The heating device is used for heating the collection inclined plane. The body part is used for judging that accumulated objects exist on an outdoor unit and starting the heating device when the weight on the collection inclined plane is gradually increased, so that whether the accumulated objects on the outdoor unit of an air conditioner are accumulated snow or sundries is further determined according to the weight change, before and after heating, on the collection inclined plane. The accumulated snow detection device can conveniently and accurately detect whether the accumulated snow exists on the outdoor unit of the air conditioner or not, and has the beneficial effect that the accumulated snow detection precision is high.

Description

technical field [0001] The invention relates to the technical field of air-conditioning manufacturing, in particular to a snow detection device, method and air-conditioning system. Background technique [0002] Since the outdoor unit of the air conditioner is usually installed outdoors, when it encounters heavy snow, the outdoor unit may gradually be covered with snow. In severe cases, the heat exchanger of the outdoor unit is blocked, and the outdoor fan cannot operate normally, which may cause the Damage or deterioration of the heating effect will seriously affect the normal use of users; in addition, when it rains in cold weather, the freezing rain will easily freeze the outdoor fan, which may cause the outdoor unit to fail to operate normally and burn out. [0003] In related technologies, a snow accumulation judging device and a snow removal control method have been introduced. A snow accumulation judging device includes a heating module and a flow detection module. Th...
