By increasing the number and placing the fulcrum 14 away from a frequently occurring location, the click feeling at the time of operation is improved and the operability can be improved.

  As another configuration of the operation switch unit 6, a gear mechanism is connected to the printed circuit board 7 on which the receiving unit 9 is mounted, a part of the gear is protruded on the back side of the operation switch unit 6, and the gear is rotated. Therefore, the angle of the printed circuit board 7 can be changed. With this configuration, the angle of the reception surface 10 of the reception unit 9 with respect to the operation surface 17 of the operation switch unit 6 can be changed. Other configurations are the same as those in the first embodiment.

  As described above, in the present invention, the reflection of the infrared signal by the reflector such as the wall behind the cooking appliance, the storage, the refrigerator, and the cupboard cannot be expected due to the influence of external factors such as the installation status, the floor plan, and the color of the reflector. In addition, the receiving surface 10 of the receiving unit 9 can be easily varied so that the user can easily adjust the incident angle of the infrared signal so that it can be received only when the human body is reflected. Reception performance can be ensured without being affected.

  As shown in FIG. 11, as another configuration of the operation switch unit, white printing or silk printing 16 of a color that easily reflects light is performed on the printed circuit board 7 around the terminal unit of the receiving unit 9. Although it is desirable to print in the same shape as the push button, since it is necessary to efficiently reflect the infrared signal incident from below, on the printed circuit board 7 around the terminal portion of the receiving unit 9 and on the receiving surface 10 side Only printing may be used. In addition, it is desirable from the viewpoint of cost to share with silk printing which is usually performed to display the number of electronic components mounted on the printed circuit board 7, but the present invention is not limited to this and is intended to promote light reflection. I just need it. Other configurations are the same as those in the first embodiment.

  As described above, in the present invention, the infrared signal that is slightly attenuated through the push button and the infrared filter 13 and is incident on the periphery of the receiving unit 9 is further easily reflected between the printed circuit board 7 and the push button, and is received on the receiving surface 10. The reception performance can be improved by making it easy to guide to the possible angle.

  The ventilation device according to the present invention eliminates the need for a receiving window dedicated to the receiving unit for receiving the infrared signal, and efficiently receives the receiving unit on the back surface of the push button and receives it through an infrared filter that blocks external noise. This configuration is effective in cases where downsizing of equipment or electrical components is required, and must also minimize degradation of reception performance due to external factors such as the effects of external noise from surrounding lighting equipment. This is useful in a case or a device in which the transmission source of an infrared signal is fixed and the reception performance must be ensured. Moreover, even if it employ | adopts not only about the ventilator installed above a cooking stand but the general ventilator which can be remotely operated using a remote controller etc., there exists the same effect.
