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.
摘要翻译：一种热风式烤箱，其特征在于，包括：外壳，限定加热室，所述加热室适于容纳要烹饪的食品，并具有用于打开和关闭所述加热室的前门。主燃烧器用于产生通过鼓风机送到加热室的热气。包括操作手柄的气体控制部分控制向主燃烧器和与其相邻的引燃燃烧器的气体供应。电气控制部分用于控制主鼓风机和用于引燃燃烧器的点火装置。气体控制部分和电气控制部分被构成为联接在一起并可拆卸地安装用于相互操作的各个单元。控制部分根据门的移动来操作，使得当门关闭时操作手柄被锁定，并且可以仅通过打开门并移动操作手柄来实现导向燃烧器的点亮。在引燃燃烧器照明和关闭门之后，实现对主燃烧器的供气和鼓风机的通电。此后，如果打开门，鼓风机被停止，并且主燃烧器的气体供应中断。

摘要： A safety arrangement for microwave ovens or similar cooking devices, in which a circuit breaking element and a main switch, which is arranged to be open in conjunction with an unlocking operation of a lock for a door, are interposed in a load circuit connecting between an electric source of power and a load. A first door switch is arranged to be closed when the door is opened and is connected to the load circuit in parallel with the load. An auxiliary switch becomes opened upon unlocking of the lock, and is connected in the load circuit on the load side of the first door switch. A second door switch becomes opened with a delayed time interval after closing of the first door switch, by opening of the door, and is connected to the load circuit on the electrical power source side of the first door switch. The door switches become operated by a door arm extending from the door.
摘要翻译：用于微波炉或类似烹饪装置的安全装置被插入到连接在门的锁定电路之间的负载电路中，其中断路元件和主开关被布置成与门的锁的解锁操作一起打开电源和负载。当门打开时，第一门开关被设置为关闭，并且与负载并联连接到负载电路。在锁定解锁时辅助开关打开，并且连接在第一门开关的负载侧的负载电路中。第二门开关在通过打开门关闭第一门开关之后以延迟的时间间隔打开，并且连接到第一门开关的电源侧的负载电路。门开关由从门延伸的门臂操作。
