Reference numeral (7) is a ventilation fan for starting and stopping the rotation of the fan (10) by a well-known cordless remote controller (9) mounted on the wall surface (8) around the appliance body (1) and the like. A light receiving portion (12) of the cordless remote controller (9) is provided at the lower left corner of (11), for example. Meanwhile, the top plate
The cordless remote control is on the left and right of the upper surface of (3).
Transmitting elements (13) and (13) which emit substantially the same signal as in (9) and are composed of light emitting elements such as infrared LEDs are provided.

The transmitting elements (13) and (13) are, for example, a top plate.
Although it may be attached to each corner of the upper surface of (3), the back side of the gas cooker is often located below the ventilation fan (7) in the kitchen of a general household, and the top plate as in the above embodiment is used. By arranging the transmitting elements (13) and (13) on the front side of (3), this transmitting element can be reliably arranged within the light receiving sensitivity range of the light receiving portion (12) of the ventilation fan (7).

The operation knobs (6), (6) and (6) are attached to the tip of an operation shaft (15) which is attached to the valve body (14) so as to be slidable back and forth as shown in FIG. The operation knob is formed by a combination of a well-known guide groove (16) of a heart shape provided at a proper position of this operation shaft and a pin (17) engaged with the guide groove (16).
By pushing the operation axis (15) with (6),
The valve shaft (19) provided with the main valve (18) and the solenoid valve (20) are opened and closed to operate the gas supply to the burner (4) (4) for the stove and the operation shaft (15). Actuator integrally formed on the
At (21), when the operating shaft (15) is pushed into a predetermined ignition position, a detection switch (22) composed of, for example, a micro switch is activated, and this detection switch simultaneously activates an igniter (not shown). , The ventilation fan interlocking circuit (2
The rotation start or stop signal of the ventilation fan (7) is transmitted from the transmitting elements (13) and (13) via 3).

The ventilation fan interlocking circuit (23) includes detection switches (22) (22) (2) arranged on the valve bodies (14) (14) (14).
Switch detection circuit (24) that detects the on / off state of 2)
And the transmitter element according to the output of this switch detection circuit.
(13) All the burners are turned off when the transmission signal generator circuit (25) that drives (13) and the detection switches (22), (22) and (22) are all turned off.
(4) After the combustion of (4) is stopped, the on / off state of the mode changeover switch (26) for setting whether to stop the operation of the immediate ventilation fan (7) or stop it after a predetermined time is detected, It mainly comprises a delay setting circuit (27) for outputting a mode setting signal to the transmission signal generating circuit (25).

Then, one of the operation knobs (6) (6) (6)
When the burner (4) (4) is ignited by the operation of and the detection switches (22), (22) and (22) are turned on, this is detected by the switch detection circuit (24), and this switch detection circuit A ventilation fan operation signal is output to the transmission signal generation circuit (25), and the transmission element (13) (13) is driven by this transmission signal generation circuit,
A rotation start signal is transmitted from the transmitting element to the ventilation fan (7).

When the operation knobs (6), (6) and (6) are operated to turn off all of the detection switches (22), (22) and (22), the switch detection circuit (24) detects this and The switch detection circuit outputs a ventilation fan operation stop signal to the transmission signal generation circuit (25), and the transmission signal generation circuit (25) causes the transmission element (13) (1
3) is driven, and the rotation stop signal is transmitted to the ventilation fan (7) from this transmitting element.

On the other hand, at this time, the transmission signal generating circuit (25) detects the output of the delay setting circuit (27), and the mode selector switch (2)
When delay stop is set by turning on or off 6), drive the transmitting elements (13) (13) after a predetermined time has elapsed after all of the detection switches (22) (22) (22) are turned off. And ventilation fan (7)
If the mode stop switch (26) is not set to delay stop, the detection switch
(22) (22) (22) interlocking with the off operation, transmitting element (13) (13)
It sends the rotation stop signal of the ventilation fan (7).

[0015]

With the structure according to the present invention, the ventilation fan can be operated in conjunction with the start and stop of use of the gas cooker without using a dedicated ventilation fan and without performing wiring work. It is possible to prevent waste of electric power due to forgetting to stop the ventilation fan, and it is possible to significantly reduce the time and effort to operate the ventilation fan, and to prevent kitchen pollution and odor adhesion due to forgetting to operate the ventilation fan.

Further, by arranging the transmitting element for the cordless remote controller in front of the top plate of the main body of the appliance, the transmitting element can be positioned within the light receiving sensitivity range of the light receiving part of the ventilation fan, and the malfunction of the remote controller operation is prevented as much as possible. You can do it. Furthermore, by providing a delay setting circuit in the ventilation fan interlocking circuit to selectively set whether to stop the rotation of the ventilation fan immediately after the gas cooker is stopped or to stop it after a lapse of a predetermined time, without forgetting to stop the gas fan The hot air remaining in the kitchen after stopping the use of the cooker can be reliably discharged.
