    • The immersion heater for an appliance includes a mounting plate, a metal sheathed electrical resistance heating element having two end portions which extend through and which are secured to the mounting plate, and a single fastening device for fixing the mounting plate to the body shell of the appliance. The fastening device comprises a threaded heat conductive stud secured to the mounting plate and a nut having a complementary thread. A raised part of the active portion of the heating element is directly secured to and only to the stud, such as by brazing. A bimetallic element is fixed directly to the stud on the outside of the body shell. The stud provides a heat conductive path between the heating element and the bimetallic element. The bimetallic element bends when the appliance is energized `dry` or when the liquid has boiled down to the element and pushes a dolly overcenter to open a pair of contacts and de-energize the heating element. The appliance is, preferably, an electric kettle provided with a further bimetallic element which switches off the kettle when water therein boils.
    • 用于器具的浸入式加热器包括安装板,金属护套电阻加热元件,其具有延伸穿过并固定到安装板的两个端部,以及用于将安装板固定到壳体的单个紧固装置 器具。 紧固装置包括固定到安装板上的螺纹导热螺柱和具有互补螺纹的螺母。 加热元件的活动部分的凸起部分直接固定到螺柱上,例如通过钎焊固定。 双金属元件直接固定在主体外壳的螺柱上。 螺柱在加热元件和双金属元件之间提供导热路径。 当设备通电“干燥”或当液体已经沸腾到元件并推动小车过载中以打开一对触点并使加热元件断电时,双金属元件弯曲。 该设备优选地是具有另外的双金属元件的电热水壶,当其中的水沸腾时,该电池将其关闭。

    • The appliance, e.g. an electric kettle, has a body shell, a heating element within the body shell and a switch housing mounted on the outside of the body shell. A switch operating member or dolly is supported relative to the switch housing and is operable to open and close a pair of switching contacts for interrupting and making respectively an electrically conductive path, which includes the heating element, between a pair of terminal pins. The dolly can rock about a pivot between two positions and is urged against the pivot by a leaf spring acting between the dolly and a support. The housing includes the pivot and the support and is formed as an integral plastics moulding.
    • 器具,例如 一个电热水壶,具有一个主体外壳,一个主体外壳内的加热元件和一个安装在主体外壳外面的开关外壳。 开关操作构件或台车相对于开关壳体被支撑,并且可操作地打开和关闭一对开关触点,以分别在一对端子引脚之间分别形成包括加热元件的导电路径。 小车可以围绕两个位置之间的枢轴摇摆,并通过作用在台车和支架之间的板簧推动抵靠枢轴。 壳体包括枢轴和支撑件,并且形成为整体塑料模制件。
