Title:
WARM AIR HEATER
Document Type and Number:
Japanese Patent JP2017048947
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem in which, even when a light receiving range of infrared rays is narrowed by providing human body detection means 25 in the depth of a body opening 32, the infrared rays pass through a frame body 2 depending on a component material of the frame body 2, and the human body detection means 25 determines that there is a person even when there is none.SOLUTION: The periphery of a display part plate opening 34 is covered, and an infrared ray cutoff plate 33 is provided in which a cutoff plate opening 36 is formed at a position in front of the display part plate opening 34. Thus, irrespective of the component material of a frame body, the infrared rays do not pass the frame body, and occurrence of erroneous detection can be surely prevented in which human body detection means determines that there is a person even when there is none.SELECTED DRAWING: Figure 4
