Definitions
- the invention relates to ceramic cooker hobs.
- hobs normally consist of a hob top comprising a plate of ceramic glass held in a metal mounting, usually comprising a frame fabricated from aluminium extrusions or rolled steel sections.
- the ceramic glass sheet may be secured in the frame by a gap-filling adhesive, thereby avoiding the formation of a dirt trap at the edge of the sheet.
- An object of the present invention is to provide an alternative construction for a ceramic cooker hob which is simple and inexpensive to manufacture, which is particularly adapted for use with halogen-type heater elements in that it reduces the escape of stray light, and which, in some cases, permits a thinner ceramic plate to be used.
- the cooker hob shown in the drawing comprises a ceramic glass sheet 1 forming the hob top mounted in a panel 2 pressed from sheet steel.
- the upper surface of the panel has a shallow recess large enough to accommodate the ceramic sheet, and having a flat bottom 3, so forming a shallow tray.
- cutouts 4 and 5 are formed below which, when the cooker hob is fully assembled will be placed the heating elements which may comprise spiral resistive heaters, or preferably, radiant heaters of the halogen type.
- the ceramic glass sheet 1 rests on spacers 6 which are provided at intervals under the edges of the ceramic glass sheet, and preferably also in the central region between the heater apertures 4, 5.
- the groove round the edge of the ceramic glass plate is filled with a gap-filling adhesive, as shown at 7.
- the sheet steel pressing 2 is relatively inexpensive to produce, does not require time to be spent on assembly, and does not have corner joints which could act as dirt traps.
- the tray-like bottom of the recess obstructs stray light from the heaters, particularly if halogen type heaters are used, so that light from them is not visible outside the area of the hob ring itself.
- the additional support provided by this construction means that in some cases a thinner plate of ceramic glass may be used, for example 3 millimetres thick instead of the 4 millimetre thickness commonly now employed.
