が知られる（特公昭51−26507号公報参照）。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a preheating completion notification circuit for a heating appliance equipped with a temperature regulator, such as a cooker. Conventional thermos circuits of this type turn on when the temperature is adjusted to a set temperature to drive a heating device (heater), and turn off when the actual preheating temperature reaches or exceeds the set temperature by driving the heating device. A device is known that includes a thermostat and an alarm (buzzer) that is driven by the OFF operation of the temperature regulator (see Japanese Patent Publication No. 51-26507).

が無駄に消費されてしまう不都合を生じる。 According to this, when the thermostat turns OFF, the heater is immediately stopped and a buzzer sounds, which notifies the completion of preheating, but after the heater stops, the actual preheating temperature is lower than the set temperature. The buzzer disappears in a relatively short period of time due to the drop in temperature, so if you miss this sound, the buzzer will sound again until the actual heating temperature returns to the set temperature or higher by subsequent heater drive. , it is not possible to know when preheating is complete, and electrical energy is wasted by the heater for a relatively long period of time.

直ちに調理加熱にうつることができる。 Next, to explain its operation, first set the temperature control knob of the thermostat to the desired set temperature, then the lever switch that constitutes the normally open switch 7 is closed and the thermostat is turned on.
When activated, the contact 4 switches to the side where it comes into contact with the second fixed contact 21. Next, when the operation knob of the timer 16 is set to the preheating position, the first contact 17 and the third contact 19 are closed, and the preheating preparation is completed. After completion of preparation, when the start switch 13 is closed, the combustion control device 12 is activated, the burner constituting the heating appliance 1 is ignited, and preheating of the inside of the oven is started. After preheating starts, when the actual preheating temperature inside the oven reaches the desired set temperature, the thermostat will turn on.
OFF operation causes the contact 4 to contact the first fixed contact 8 again, the relay 5 is energized, the contact 14 is closed, and the buzzer constituting the alarm 3 is sounded. This sounding is continued by the relay 5 being self-held by closing its contact 15, so the notification of the completion of preheating is not missed, and the cooking heating can be started immediately thereafter.

されてしまうからである。 If the normal operating procedure of setting the timer 16 after setting the thermostat 2 as described above is followed, the alarm will be sent only when the temperature inside the oven reaches the desired set temperature even if the switch 7 is not always open. The thermostat 2 is set after the timer 16 is set, and if the switch 7 is not present, the thermostat 2 cannot be set. If such an erroneous operation procedure is followed, the relay 5 will be energized from the moment the start switch 13 is closed, its contact 14 will be closed, and the alarm 3 will be driven.

を確実になくし得られる効果を有する。 In this way, according to the present invention, a self-holding type relay 5 is provided which is energized through the contact 4 which contacts the first fixed contact 8 when the thermostat 2 is turned OFF, and drives the alarm 3. The alarm 3, which is activated when the preheating is completed, can be driven continuously after that, so that the next heating process can be started immediately without failing to detect the completion of the preheating, and the heating process can be started after the completion of the preheating. This has the effect of reliably eliminating the inconvenience of wasting electrical energy as in the conventional circuit described above, which sometimes fails to detect the completion of preheating before operation.

る。 Further, according to the present invention, the energizing circuit 6 of the relay 5 includes a normally open switch 7 that is closed when the thermostat 2 is operated to the temperature set position, and a timer 1.
Since the third timer contacts 19, which are closed when the temperature is set to the preheating position, are connected in series, the relay 5 is energized before the temperature is set, and the alarm 3 is not driven, thereby preventing false alarms. It has the effect of preventing
