    • PURPOSE:To save the maximum power consumption of a total electric range by a method wherein heaters are constituted so that a heating element of a specified heater may be disconnected only when a loaster is actuated in case all heaters are fully operated. CONSTITUTION:While heaters 1, 2, 3 are operated, switches 13, 14, 15 are closed and relays 18, 19 are actuated to open switches 21, 22 but another switch 23 is closed while heating elements 9, 10, 11 of the heaters 1, 2, 3 are made conductive. When another switch 17 is closed to actuate a loaster 4 in this status, the heating element 12 of the loaster 4 is made conductive simultaneously actuating a relay 20 to open another switch 23 automatically disconnecting the heating element 11 of the heater 3. Besides, for example while the heater 3 only is operated, the switches 21, 22, 23, 15 are closed all together. When the switch 17 is closed to actuate the loaster 4 in this status, the heating element 12 of the loaster 4 is made conductive simultaneously actuating the relay 20 to open the switch 23. Therefore only when the loaster 4 is actuated in case the heaters 1, 2, 3 are simultaneously operated, the heater 3 is disconnected affording a preference to make the loaster 4 conductive.
    • 目的:通过一种方法来节省总电气范围的最大功耗,其中构成加热器,使得只有当所有加热器完全操作的情况下致动破坏器时,才能使指定加热器的加热元件断开。 构成:当加热器1,2,3工作时,开关13,14,15关闭并且继电器18,19被致动以打开开关21,22,但是另一个开关23关闭,而加热器的加热元件9,10,11 1,2,3导通。 当另一个开关17闭合以致动这个状态下的破坏器4时,制动器4的加热元件12同时致动继电器20,以使另一个开关23自动断开加热器3的加热元件11,此外,为了 在加热器3仅被操作的情况下,开关21,22,23,15全部关闭。 当这种状态下开关17闭合以致动器5时,制动器4的加热元件12同时致动继电器20以打开开关23.因此,只有当加热器1 ,2,3同时操作,加热器3断开,提供了使破坏器4导通的优点。
