PURPOSE:To simplify the configuration of a heat exchanger and facilitate a maintenance such as cleaning and the like by mounting partition plates for preventing the mixing of a primary air current with a secondary air current between a blower and a heat exchanger, on the main body of the ventilation fan and a louver. CONSTITUTION:The wall 7 of a ventilation fan main body 3 and the wall 9 of a louver are formed integrally with casings 6 and 8, and have a function to prevent a primary air current and a secondary air current between an air blower 16 and a heat exchanger 1 from mixing with each other. By loading the louver 4 in the ventilation fan main body 3, the heat exchanger 1 is pinched between the wall 7 of the heat exchanger main body 3, provided with a cutaway and the wall 9 of the louver 4, provided with a cutaway, and thus fixed with each other. Further, upon the maintenance of the heat exchanger 1 such as cleaning and the like, the louver 4 is removed from the ventilation fan main body 3 and can be taken out. As described in the foregoing, the housing 2 of the heat exchanger 1 may be of a shape provided only with a function for preventing the primary air current and a secondary air current from mixing with each other. Therefore, the ventilation fan has a simple configuration and is easy for performing such cares as cleaning and the like. |
