Description

Refrigerator with a refrigerator body Technical Field An aspect of the present invention relates to a refrigerator having a machine room. Background In order to insulate heat from the surroundings, a heat insulation box is provided in the refrigerator so as to cover the outer periphery of the storage space. A machine chamber is provided below the rear surface side of the heat-insulating box, and a compressor or the like constituting a refrigeration cycle is disposed in the machine chamber. The refrigerator further includes a control board for controlling electronic components such as the compressor. As shown in, for example, japanese patent application laid-open No. 10-148463, the control board can be disposed in the machine room. In the refrigerator disclosed in japanese unexamined patent publication No. 10-148463, an electric component housing box housing a control board is supported by a reinforcing plate and disposed in a machine room. Thus, the heat generation of the control substrate does not affect the inside of the refrigerator. Disclosure of Invention However, in the structure disclosed in japanese patent application laid-open No. 10-148463, the influence of heat generation of the control board on the inside of the refrigerator can be avoided, but it is difficult to release the heat generated in the control board, and there is a possibility that the heat accumulates in the electric component housing box or the machine room. Accordingly, an object of the present invention is to provide a refrigerator in which heat generated on a control board in a machine room can be easily dissipated. The refrigerator according to one aspect of the present invention includes a heat-insulating box, a machine room provided below the heat-insulating box, a compressor disposed in the machine room, a control board disposed beside the compressor, and a housing member housing the control board. The back surface of the housing member and the surface of the housing member opposite to the compressor are covered with a good heat conductive member. According to an aspect of the present invention, a refrigerator in which heat generated by a control substrate in a machine room can be easily dissipated can be provided.
