Ventilation fan with illumination instrument and human motion perception sensor

Abstract

The invention relates to a structure of a ventilator with an illuminating implement and a human-sensing sensor. The structure comprises a ventilator body and a mask; an exhaust inlet, a lamp as the illuminating implement and the human-sensing sensor are arranged on the mask; a lamp cover and the exhaust inlet are arranged on the middle part of the mask; the human-sensing sensor is arranged in the peripheral position of the mask, and the installation direction of the mask is changeable. The human-sensing sensor is arranged in the peripheral position of the mask so as to keep away from a lampshade and a wind inlet, thus ensuring that the human-sensing sensor is not affected by the heat emitted from the lampshade; furthermore, as the installation direction of the mask is changeable, the human-sensing sensor can be arranged in the position with best sensing effect.

Description

technical field [0001] The invention relates to a ventilation fan. Background technique [0002] Ventilation fan is a common indoor ventilation equipment. The ceiling fan is installed on the ceiling. The mask of this type of ceiling fan is installed on the ceiling with an air suction port. [0003] There is a kind of ceiling fan, the center of the mask is equipped with a human sensor with human body induction that can automatically operate, and can know whether there is human activity in the room through wireless sensing technology, so as to automatically turn on or off the ceiling fan, and control its only Energy can be saved by running when people are present. The reason why the human sensor is set in the center is because it can sense the situation in the room to the greatest extent. [0004] There is also a kind of ceiling fan, which is a ceiling fan with lighting, and a lighting device is installed on the center of the mask of the ceiling fan. [0005] If it is desir...

Problems solved by technology

[0006] However, since the body of the ventilation fan is not necessarily installed in the central part of the room, and the structure of the room is different, it is quite difficult to make the human sensor not be affected by the lighting equipment, and to be able to fully sense the design.

[0007] As shown in Figure 1, due to the limitation of the house structure, when the ventilation fan 100 is installed at the corner 800 on the side of the ceiling close to the wall, and after the mask 200 of the ventilation fan is installed, the human sensor 300 is arranged far away from the lighting fixture (not shown in the figure). shown) but it is in the corner of the room, it is difficult to sense
