(More specifically, the center point of the globe 40 of the halogen lamp 4) and the direction defined by the delivery flow path 71 can be brought closer to the front and rear horizontal directions, so that the infrared rays emitted from the halogen lamp 4 are sent to the delivery flow path. It can be made difficult to leak out of the reflector 10 via 71. Therefore, it is possible to reliably prevent the reflection efficiency and the light collection rate of the reflector 10 from being reduced due to the formation of the delivery channel 71.

This is because if the delivery flow path 71 is arranged on the rear side of the front / rear direction of the reflector 10, air stays on the front end side of the reflector 10, and exhaust heat due to the airflow is not performed.
  • the delivery channel 71 is arranged on the rear side, it is defined by the halogen lamp 4 (more specifically, the center point of the globe 40 of the halogen lamp 4) and the delivery channel 71. Since the direction to be reflected approaches the direction orthogonal to the front-rear direction (see FIG. 7B), the infrared rays emitted from the halogen lamp 4 leak directly from the reflector 10 via the delivery channel 71 and are reflected by the reflector 10. This is due to a decrease in efficiency and light collection rate.
  • the opening length dimension (w1) of the delivery channel 71 in the front-rear direction is set to 5 mm or less. This is because when the length width dimension (w1) of the delivery flow path 71 exceeds 5 mm, the opening becomes too large, and the venturi effect is not exhibited well, and the delivery flow path 71 is sent to the dry air flow path 52. This is because the amount of air to be reduced is reduced and the reflection efficiency and the light collection rate of the reflector 10 are reduced.

Abstract

L'invention concerne un séchoir, notamment pour sécher les cheveux, qui utilise des rayons thermiques de rayonnement et évacue la chaleur depuis l'intérieur d'un réflecteur sans réduire l'efficacité de réflexion du réflecteur. Un trajet d'écoulement d'entrée (70) est formé uniquement sur la partie d'extrémité arrière d'un réflecteur (10), et un trajet d'écoulement de sortie (71) est formé uniquement sur la partie d'extrémité avant du réflecteur. Ceci permet d'agrandir la zone de réflexion du réflecteur par rapport à une configuration dans laquelle un grand nombre de trajets d'écoulement d'entrée et de trajets d'écoulement de sortie sont formés sur l'ensemble du réflecteur, et permet ainsi une amélioration de l'efficacité de réflexion. En outre, la pression interne de trajet d'écoulement d'un trajet d'écoulement d'air sec (52) dans une région de formation du trajet d'écoulement de sortie du réflecteur se trouvant sur le côté aval est réglée pour être inférieure à la pression interne de trajet d'écoulement du trajet d'écoulement d'air sec (52) dans la région de formation du trajet d'écoulement d'entrée du réflecteur se trouvant sur le côté amont. La configuration précédente permet d'utiliser l'effet Venturi de façon à créer un écoulement d'air qui passe à travers l'intérieur du réflecteur à partir du trajet d'écoulement d'admission et atteint le trajet d'écoulement d'air sec par l'intermédiaire du trajet d'écoulement de sortie, ce qui permet d'évacuer efficacement la chaleur à l'intérieur du réflecteur.
