The height of the air supply fan 2 is made higher than that of the circulation fan 3, and the diameters of the air supply fan 2 and the circulation fan 3 are substantially the same. Here, each fan uses a sirocco fan capable of centrifugal air blowing, and can be detached from the electric motor 1 without a tool.

  Further, a blower having a supply casing 4 that forms a flow path of the supply fan 2 and a circulation casing 5 that forms a flow path of the circulation fan 3 is built in the main body 19. 4 is formed of expanded polystyrene having a high heat insulating effect. The main body 19 is fixed to the blower, and includes a frame 19a constituting the wall surface side of the main body 19 and a panel 19b constituting the indoor side of the main body 19, and the panel 19b has a detachable structure.

  The frame 19a penetrates the wall 20, and the air supply duct 6 is connected to the outside and the room. The panel 19b is connected to the circulation casing 5, and is connected to the indoor circulation exhaust port 8 and the indoor circulation air supply port 7. The indoor air supply port 9 communicating with the casing 4 is provided, the electrostatic atomizer 16 is provided in the circulation path, and the indoor circulation air supply port 7 and the indoor air supply port 9 are provided in the vicinity. . An outdoor hood 21 is attached to the outside end of the air supply duct. Further, a filter 10 capable of collecting dust or dust supplied from outside air is disposed in the air supply air path between the air supply duct 6 and the air supply fan 2, and the filter 10 is a top view of the main body. In some cases, the filter 10 is disposed obliquely with respect to the wall surface, and the filter 10 has an outer case formed of a resin case and can be pulled out from the lower portion of the main body 19 without removing the panel 19b. Can be removed. A shutter 11 is provided between the air supply duct 6 and the air supply casing 4, and the shutter 11 can be opened and closed by operating a knob 17 discharged from the lower part of the main body 19.
