The present invention relates to a refrigerator condenser cleaning device. More specifically, the present invention relates to a refrigerator condenser cleaning device for removing foreign matters accumulated in the condenser of the refrigerator to improve refrigerator performance.

Refrigerators that store food at low temperatures to prevent corruption and deterioration or to keep drinks cold are widely used. These refrigerators can be divided into household and business.

1 is a perspective view of a conventional refrigerator configured in a showcase shape, and FIG. 2 is a front view illustrating a state in which a condenser panel is removed from the refrigerator illustrated in FIG. 1.

1 and 2, the refrigerator 1 shown in FIG. 1 and 2 is provided with a substantially rectangular case 2 having an open front side, and an open front side of the case 2, one side of which is provided in the case 2. It includes a door (3) hinged to the hinge portion 4 is rotatably coupled. In addition, the lower part of the door (3) is provided with a removable condenser panel (5) for repair or the like. The condenser 6 is provided inside the condenser panel 5. Referring to FIG. 2, the condenser 6 includes a condenser frame 7 forming the outline of the condenser and a heat exchanger 8 that facilitates heat exchange between the refrigerant and the air.

Briefly, the operation principle of the refrigerator is to compress the refrigerant to a high temperature and a high pressure in the compressor, the refrigerant discharges heat in the condenser and liquefies, and the refrigerant passing through the expansion valve vaporizes in the evaporator to take heat inside the refrigerator. Cool the inside. Refrigeration efficiency requires effective heat exchange in each component of the refrigerator. However, since the condenser is exposed to air outside the refrigerator, foreign matters such as dust attached to the surface of the heat exchanger of the condenser may cause a problem of deteriorating the heat exchange efficiency.

As a way to solve this problem, Korean Patent Laid-Open Publication No. 2003-0086602 (published Nov. 10, 2003) describes a technique for cleaning the condenser by rotating the cooling fan adjacent to the condenser forward and reverse.
