ABSTRACT:
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.
