Title:
VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/170880
Kind Code:
A1
Abstract:
A ventilation device (2) comprising: fans (22, 22A, 23A) that draw in and blow out air by rotating; an electric motor (25) that rotates and drives the fans (22, 22A, 23A); and induction heating coils (51, 52, 55, 56) that heat the fans (22, 22A, 23A) by induction heating. The fans (22, 22A, 23A) have: a plurality of blades (221, 221A, 231A) arranged having intervals therebetween such that air can flow therethrough; and coupling sections (223, 26) that couple the plurality of blades and transmit the rotational drive force from the electric motor (25) to the plurality of blades (221, 221A, 231A). In addition, the plurality of blades (221, 221A, 231A) comprise a material having a higher thermal conductivity than the coupling sections (223, 26). The coupling sections (223, 26) comprise a material having a higher cumulative value for magnetic permeability and electric resistance than the plurality of blades (221, 221A, 231A).
