RADIATION RECEIVING SENSOR AND AIR CONDITIONER, ELECTRONIC COOKER, AND TRANSPORT DEVICE INCLUDING THE SAME

摘要

A radiation receiving sensor includes an infrared receiver including a plurality of infrared receiving devices that receive infrared radiation, a lens that allows infrared radiation to enter the infrared receiver, a rotator that rotates the infrared receiver and the lens about a part of the lens, and a cover member that faces the infrared receiver through the lens and that has translucency.

主权项

1. A radiation receiving sensor comprising:
an infrared receiver including a plurality of infrared receiving devices that receive infrared radiation; a lens that allows infrared radiation to enter the infrared receiver; a rotator that rotates the infrared receiver and the lens about a part of the lens; and a cover member that faces the infrared receiver through the lens and that has translucency, wherein the lens allows infrared radiation that has passed through the cover member to enter the infrared receiver, wherein the cover member includes a first area having a first infrared transmittance and a second area having a second infrared transmittance, which is lower than the first infrared transmittance, and wherein a minimum value of a distance between a position at which infrared radiation that has entered the second area goes out and a rotation center of the lens is larger than a distance between a position at which infrared radiation that has entered the first area goes out and the rotation center of the lens, and a minimum value of an optical length, in the second area, of infrared radiation that passes through the second area and the rotation center of the lens is larger than an optical length, in the first area, of infrared radiation that passes through the first area and the rotation center of the lens.
