Patent attributes
An air conditioning structure for an electrical appliance, which is capable of air-cooling at least one heat-generating electrical component part in a housing of the electrical appliance while suppressing leakage of operation noise from an air intake fan to the outside, and also capable of achieving a muffling effect and even enhancing the rigidity of the front part of the housing by the front part being constructed of a double structure. The housing accommodates at least one electrical component part group. In the housing, a double plate assembly has a double structure and is comprised of a front plate and a rear plate. The housing has a rear plate provided with two windows and two exhaust fans, which form an exhaust section. The front plate is formed therein with two outer air intake openings, while the rear plate is formed therein with an inner air intake opening. An air intake fan is provided at the front part of the housing at a location rearward of the outer air intake openings in facing relation to the inner air intake opening, and disposed at such a location that it does not overlap the outer air intake openings at all as viewed from a front side of the housing. The electrical component part group is air-cooled by the air intake fan and the exhaust section.
