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

The operation knobs (6), (6) and (6) are mounted on the tip of an operation shaft (15) slidably mounted on the valve body (14), for example, as shown in FIG. The operation knob is formed by combining a well-known, for example, heart-shaped guide groove (16) provided at an appropriate position of the operation shaft with a pin (17) engaged with the guide groove.
By performing push-push operation on the operation axis (15) in (6),
The valve shaft (19) provided with the main valve (18) and the solenoid valve (20) are opened and closed to operate gas supply to the stove burners (4), (4), etc., and the operating shaft (15) Actuator integrally formed with
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 operated, and at the same time, an igniter (not shown) is operated by this detection switch. , The ventilation fan interlocking circuit shown in FIG.
A signal to start or stop the rotation of the ventilation fan (7) is transmitted from the transmission elements (13) and (13) via 3).

The ventilation fan interlocking circuit (23) is provided with detection switches (22), (22), (2) disposed on the valve bodies (14), (14), (14).
Switch detection circuit (24) that detects the ON / OFF state of 2)
And the transmitting element according to the output of the switch detection circuit.
(13) The transmission signal generation circuit (25) that drives (13), and all of the detection switches (22), (22), and (22) are turned off and all burners
(4) After the combustion of (4) is stopped, an on / off state of a mode changeover switch (26) for setting whether to stop the operation of the immediate ventilation fan (7) or to stop 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).

Thus, one of the operation knobs (6), (6), (6)
When the burners (4) and (4) are ignited and the detection switches (22), (22) and (22) are turned on by the operation of (1), this is detected by the switch detection circuit (24). A ventilation fan operation signal is output to the transmission signal generation circuit (25), and the transmission signal generation circuit drives the transmission elements (13) (13),
A rotation start signal is transmitted from this transmission element to the ventilation fan (7).

When the operation knobs (6), (6) and (6) are operated and all of the detection switches (22), (22) and (22) are turned off, this is detected by a switch detection circuit (24). 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) outputs the transmission elements (13) (1).
3) is driven, and a rotation stop signal is transmitted from this transmission element to the ventilation fan (7).

On the other hand, at this time, the transmission signal generation circuit (25) detects the output of the delay setting circuit (27) and
If delay stop is set by turning on or off 6), after all of the detection switches (22), (22), and (22) have been turned off for a predetermined time, the transmission elements (13) and (13) are driven. And ventilation fan (7)
When the mode stop switch (26) is not set to delay stop, the detection switch is
(22) (22) In conjunction with the off operation of (22), the transmitting element (13) (13)
A rotation stop signal of the ventilation fan (7) is transmitted.

[0015]

According to the structure of the present invention, the ventilation fan can be operated in conjunction with the start and stop of the 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, to greatly reduce the trouble of operating the ventilation fan, and to prevent contamination of the kitchen and adhesion of odor due to forgetting to operate the ventilation fan.

In addition, by disposing the transmitting element for the cordless remote control in front of the top plate of the main body of the apparatus, the transmitting element can be located within the light receiving sensitivity range of the light receiving portion of the ventilation fan, thereby preventing malfunction of the remote control operation as much as possible. You can do it. In addition, the ventilation fan interlock circuit is provided with a delay setting circuit that selectively sets whether to stop the rotation of the ventilation fan immediately after the use of the gas cooker or to stop after the lapse of a predetermined time, without forgetting to stop the ventilation fan, The hot air remaining in the kitchen after the use of the cooker is stopped can be reliably discharged.
