摘要： A water heater is disclosed having a main burner for heating a heat exchanger and a standing burner, and is also provided with an electromagnetic safety valve which is opened by a manual operation member and which is kept in its valve open condition by the electric current from a thermocouple element exposed to the standing burner and a water pressure sensitive member such that it opens in response to a supply of water to the heat exchanger (that is, the water flow is turned on). Both the electromagnetic safety valve and the water pressure sensitive valve are interposed in a fuel passage connected to the main burner. A standing burner fuel passage is connected on one end to the standing burner and is connected at its other end to a point located in between the two valves. Additionally there is provided a control circuit which has a capacitor, a discharging circuit for the capacitor having a solenoid operating the electromagnetic safety valve, and a changeover switch adapted to be switched by the manual operation member for charging or to the discharging circuit for discharging. A subsidiary discharge circuit for the capacitor is further provided having a switch which is interposed therein, and adapted to be closed when the supply of water to the heat exchanger is on. The subsidiary discharging circuit is in parallel with the foregoing discharging circuit, and a resistance is interposed between the two discharging circuits. Thus, when the control switch is closed and the subsidiary discharging circuit conducts, the solenoid does not become actuated and the electromagnetic safety valve is closed.

摘要： A hot blast type oven comprising an outer casing defining a heating chamber adapted to receive foodstuff to be cooked and having a front door for opening and closing the heating chamber. A main burner serves for producing hot gases sent to the heating chamber by a blower. A gas control section including an operation handle controls the supply of gas to the main burner and to a pilot burner adjacent thereto. An electrical control section serves for controlling the main blower and an ignition device for the pilot burner. The gas control section and the electrical control section are constituted as respective units coupled together and detachably mounted for mutual operation. The control sections are operated in accordance with movement of the door such that the operation handle is locked when the door is closed and lighting of the pilot burner can be achieved only by opening the door and displacing the operation handle. After lighting of the pilot burner and closure of the door, gas supply to the main burner and energization of the blower are effected. Thereafter, if the door is opened the blower is deactuated and the gas supply to the main burner is interrupted.

摘要： A cooking device with a microwave heater and a gas heater as well as a cooling fan for the microwave heater. A first circuit operates the microwave heater and is connected to a source of electric power through a first switching circuit. A second circuit operates the gas heater and is connected to the electric source of power through a second switching circuit, as well as a switch arranged to be operated with a gas cock. A driving circuit for the cooling fan is connected to that switch so as to be parallel with a circuit connecting in series the second circuit and the second switching circuit. The switch, furthermore, has a first contact connected to the electric source of power through the first switching circuit and has a second contact connected to the source of power without passing through the first switching circuit, while being arranged to be connected to the first contact when the gas cock is closed and to the second contact when the gas cock is opened.
