    • A heating system heats casseroles placed on trays on a passenger plane. The heating system includes heating plates vertically arranged at regular intervals to receive the casseroles between adjacent heating plates to heat each casserole from above and from beneath. The heating plate includes a ceramic plate, a heating element buried in the ceramic plate, electrodes projecting from the ceramic plate, and a reinforcing frame. The heating plate is attached to the inner surface of a side wall of a cabinet. The junction of the heating plate and the side wall is sealed in a water-tight manner. The heating system is connected to a power supply by connecting a receptacle connector fixedly provided on the cabinet, and a plug connector elastically supported on a fixed part of the galley of the passenger airplane so as to be vertically, horizontally and axially movable. When the receptacle connector is pressed against the plug connector, the plug connector is brought automatically into alignment with the receptacle connector. A tray is provided with a partition rib partitioning off a part of the surface of the tray to make a heating portion for receiving a casserole thereon. The casserole is surrounded closely by the partition rib and portions of a peripheral rib so that the heat of the casserole is not released outside. A casserole has a pan and a top formed of a heat-transmissive, transparent plastic.
    • 加热系统加热放置在乘客平台上的托盘上的砂锅。 加热系统包括以规则间隔垂直布置的加热板,以接收相邻加热板之间的砂锅,以从上方和下方加热每个砂锅。 加热板包括陶瓷板,埋在陶瓷板中的加热元件,从陶瓷板突出的电极和加强框架。 加热板安装在机柜侧壁的内表面。 加热板和侧壁的接合处以不透水的方式密封。 加热系统通过连接固定地设置在机柜上的插座连接器和弹性地支撑在客机的厨房的固定部分上的插头连接器连接到电源,以便垂直,水平和轴向移动。 当插座连接器被按压在插头连接器上时,插头连接器被自动地与插座连接器对准。 托盘设置有分隔开托盘表面的一部分的分隔肋,以形成用于在其上接收砂锅的加热部分。 砂锅被分隔肋和外围肋的部分紧密地包围,使得砂锅的热量不会释放到外面。 砂锅具有由热透射的透明塑料形成的盘和顶部。
