PURPOSE:To reduce the number of components and permit to simplify the structure of the device by a method wherein filter retainers are formed integrally with holders, holding detachably a heat exchanger in an outer casing, in the ventilating device for air-conditioning machine or the like. CONSTITUTION:Four pieces of holders 2, holding the heat exchanger 1 detachably in the outer casing 4, are protruding integrally the filter retainers 2b from the corners 2a of both side walls respectively to support the filter 3 detachable by the heat exchanger 1. The holder 2 is formed by cutting the extruded or extracted product of metal into a necessary length. Upon the maintenance of the heat exchanger 1 and the filter 3, the cover of the outer casing 4 is opened and the heat exchanger 1 and the filter 3 can be taken out of the couter casing 4 by sliding them through the holders 2 while they can be accommodated into the outer casing 1 by reverse operations. Thus, the number of components may be reduced and the structure of the device may be simplified. |
