摘要： A temperature controlled hot plate (10) has a hot plate body (11) having an upper plane heat emitting surface (12) and a lower surface on which the heating coil (13) is provided. The heating coil is embedded in an electrically insulating substance (14) against which an elongated temperature sensor is pressed such that it is directly influenced by the heat emitted by the heating coil (13). The temperature sensor is of a kind containing an expandable medium, such as a liquid or the like. According to a preferred embodiment the temperature sensor is arranged so as to follow the heating coil along essentially the whole of its length, straight below said heating coil. According to a further preferred embodiment a cup-shaped bottom washer (24) is arranged to press the temperature sensor (16) against the insulating substance as well as against an annular flange (15) surrounding the heat generating area and being an integral part of the hot plate body (11).

摘要： In an electric hotplate (1) a hotplate body (2) is constructed in such a way that a holding element (25) provided to fix the hotplate in a hob and arranged below the hotplate can be located in a relatively small distance from the top-side respective the cooking surface (3) of the hotplate body (2). Thereby a very flat mounting arrangement is possible. For example an outer flange rim (6) of the hotplate body (2) can have a groove-like reception depression (30) for an engagement of the holding element (25), this engagement also serving a rotation prevention. It is also possible to construct the outer flange rim extremely low, e.g. in such a way that its lower edge face is located higher than the lower edge face of a central stud of the hotplate body.

摘要： A temperature sensor assembly for an automatic solid disk surface unit includes a temperature sensor enclosed in a metallic hermetically sealed generally cylindrical housing. Upper and lower centrally apertured annular disks formed of a porcelain ceramic material thermally isolate the sensor housing from the surrounding surface unit. A protective metallic skirt conforming to the outer contour of the insulating disks holds the assembly together. A layer of glaze material covers the exposed upper surface of the upper disk in the gap between the skirt and the housing to prevent the absorption of food soils.

摘要： An electric hotplate, particularly intended for continuous operation in commercial use, is provided on the bottom surface with at least two superimposed reflectors (24, 28), which in each case form the lower boundary of an insulating zone (29, 30) and while incorporating an outer flange edge (4) of hotplate (2) seal the bottom surface thereof. This leads to a very low no-load power of the electric hotplate with a very rapid response to a higher power setting.

摘要： An electric heat exchange cooking unit for use, selectively, with any one of a plurality of different cooking receptacles, has a heat exchange member including locking mechanism for mechanically constraining the flat undersurface of the cooking receptacle in intimate face to face contact with the top, flat surface of the heat exchange member upon the selected cooking receptacle being fully locked in place. The heat exchange member is of cast metal having embedded therein a continuous electrical heating element of such configuration as distributes heat substantially uniformly throughout the upper surface of the heat exchange member while at the same time providing a central opening within which is received a remote-indicating temperature sensor for measuring the degree of heat being uniformly applied to the food being cooked in the selected cooking receptacle.
