STRUCTURE FOR RADIATING HEAT IN VACUUM CLEANER WITH EXCHANGED HEAT BETWEEN HEAT RADIATING DUCT AND SUCKED AIR

摘要

PURPOSE: A structure for radiating heat in a vacuum cleaner is provided to improve the efficiency of heat radiation by directly exchanging heat between a heat radiating duct and sucked air. CONSTITUTION: A structure for radiating heat in a vacuum cleaner is composed of a fan motor assembly(110) installed at one side of a cleaner body(100) and generating suction force, a dust collecting tank(130) installed at the other side of the cleaner body and filtering sucked air, an air suction passage(140) installed between the fan motor assembly and the dust collecting tank, a circuit board(150) installed at the front of the fan motor assembly and having a through hole(150a) communicated with the fan motor assembly, and a heat radiating duct(170) coupled to the air suction passage and the through hole. A damper(190) is attached to one side of the heat radiating duct.
