Document Type and Number:
WIPO Patent Application WO/2019/155763
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent damage to an optical filter due to heat in a dryer having a light-emitting body, such as a halogen lamp, as a heat source. A body case 1 has a wind guide section 7 in which a blower fan 3 for delivering drying wind toward an outlet 9, a light-emitting body 4 as a heating source, and a reflector 10 for reflecting and guiding light emitted from the light-emitting body 4 toward the outlet 9 are disposed. A filter structure 11 for blocking the transmission of visible light is disposed in a light radiation path between the reflector 10 and the outlet 9. A substrate glass 62 of an optical filter 60 constituting the filter structure 11 is formed of a low-expansibility glass of either a crystallized glass or a quartz glass having a heat expansion coefficient of less than or equal to 7 × 10-6.
