On the inner surface of the front end of the front hood 7, there is provided a receiving section 10 for operating / stopping the blower 5 and adjusting the speed thereof based on an operation signal transmitted from a remote control transmitter 9 provided separately from the ventilation fan main body 8.

The receiver 10 has an opening 10A on one side.
A protruding piece 12 provided by folding back the lower end of the front end of the front hood 7 so as to cover the opening 10A of the box-shaped control case 11 with the inner wall of the front hood 7 opened.
And a protrusion 13 protruding inwardly from the inner surface side of the front hood 7 above the protruding piece 12, a detection sensor 14 is provided inside the control case 11, and a detection sensor is provided below the control case 11. An opening 15 for guiding an operation signal from the remote control transmitter 9 is opened in the sensor 14, and a panel 16 made of a far infrared ray transmitting material that allows infrared rays to pass therethrough is attached to the front of the ventilation fan 8. Set to receive infrared signals from.

Further, the receiving unit 10 has "off" and "weak".
By using the switch 17 in which each of the "medium" and "strong" push buttons is independent, an operation signal is generated separately from the operation signal from the remote control transmitter 9 to manually operate the blower 5 to start / stop and adjust the speed. At the same time, a main body switch operating section 20 provided with a sounding means 18 for producing a sound in response to this operation signal and a display lamp 19 for displaying the operating state at that time is provided. The kitchen 21 is exposed through an opening 21 provided on the front surface of the kitchen 7.
