Definitions

  • the invention relates to a cover for hot plates or hot plates with a mechanical thermal fuse, in particular for electric hot plates or hot plates, which are arranged in an upper plate, the hot plate slightly projecting above the upper plate and the cover being provided with a bent edge which is on supported on the top plate or on the side surfaces of the hotplate.
  • the hotplate lids used today generally only serve the decorative purpose of hiding the more or less beautiful hotplates. It often happens that a hotplate and thus the hotplate lid are heated due to technical errors or forgetfulness.
  • a temperature-responsive mechanical and acoustic alarm device is provided with a resonating body which interacts with a prestressed bimetallic disc and is designed as a cover for the hotplate. At least parts of this cover must tend to vibrate naturally, so that there are special selection and manufacturing requirements with regard to the material that can be used. In particular, the use of aluminum or aluminum alloys is prohibited.
  • the formation of the bimetallic body and its attachment with a certain pretension also complicate the overall manufacture of the device and impair its reliable function. There is also the possibility that the acoustic warning occurs only temporarily or weakly depending on a certain temperature.
  • the object of the invention is therefore to provide a cover for hot plates or hot plates of the type mentioned, in which an incorrect operation or malfunction and the resulting accidents are prevented with a technically simple and simple, reliable and particularly effective device.
  • thermal fuse is designed such that it lifts the cover due to the action of heat from the hotplate and visually indicates the heating condition of the covered hotplate.
  • the thermal fuse With the thermal fuse according to the invention, a clear and visual indication is achieved when the hotplate and the hotplate lid are warm.
  • the device is easy to manufacture and works particularly reliably because of fewer and uncomplicated-looking parts. As a result, burns. by unintended contact of the hot cooking p latte lid, destruction of the cooking or heating plate and the lid, and energy losses are avoided simple and effective.
  • the thermal fuse of the hotplate cover is activated by heating. She lifts the lid off the hotplate and visibly indicates that the lid is warm.
  • the thermal fuse can comprise one or more pre-tensioned springs, e.g. held in place by soldering with a low pour point or a bimetal snap lock so that the springs are released and effective at a certain temperature.
  • the thermal fuse can consist of a flat bimetallic spring, one end of which is attached to the underside of the hotplate cover by means of screws, rivets or spot welding. This means that lifting the cover from the hotplate is temperature-dependent and cleaning the underside of the lid is made easier.
  • a hotplate cover or a hotplate lid with thermal fuse consists of a metal lid 1, on the underside of which a flat bimetal spring 2 is attached, one end of which is fastened to the hotplate lid and the active side of which is turned (bent) against the hotplate lid.
  • a flat bimetal spring 2 By heating, the free end of the bimetal spring bends away from the hotplate cover and down against the hotplate, causing the hotplate cover to rise, as shown in FIG. 3.
