摘要： PROBLEM TO BE SOLVED: To provide a defrosting brush having structure securely removing frost, since operation (heating operation etc.) using an outdoor heat exchanger on a heat source side in a refrigeration circuit functioning as an evaporator in winter causes adhesion of frost to a heat transfer fin part of the outdoor heat exchanger on the heat source side when outside air temperature is low and thus, leading to large decline in heat exchange efficiency in a refrigerating device such as an air conditioner.
SOLUTION: The defrosting brush having two types of bristles with different length and rotated or lifted/lowered by an electric driving means is adopted. An ice portion of a fin front edge is scraped off by using the short bristles on the defrosting brush, and snowy frost on a back side of the ice portion is scraped off by the long bristles. Thus, the frost adhered to the outer surface of the heat exchanger can be securely removed.
