Abstract

A hob comprises a main panel (16) having hotplate openings (14) in which are supported respective hotplates having glass-ceramic plates (12) in such a way that the top surface of each plate (12) is flush with the top surface of the main panel (16), the plate (12) meeting the panel (16) without deviation thereof. Thereby, the top surfaces close their respective openings (14) to prevent spillage from penetrating around the hotplate edges. <IMAGE>

Description

SPECIFICATION Improvements in hobs for electric cookers This invention relates to an electric hob that may be fitted into a free-standing cooker, e.g.
the Belling "FORMAT" (Registered Trade Mark) cooker, or may be built into a kitchen work surface.
In Patent Specification No. GB-A-2138935 is described a hob having a main panel forming a supporting surface and having a plurality of openings formed in it. Each opening is associated with a glass-ceramic plate that is supported within so as to extend across and close the respective opening. Thereby spillage is prevented from penetrating between the edges of the plate and the opening. The hob also has a plurality of heating elements each located beneath and spaced from a respective one of the plates. However, in this arrangement, the opening in the main panel has an upturned lip that supports the plate at a level above that of the main panel and which detracts from the appearance of the hob.
This invention provides a hob comprising a main panel having a hotplate opening formed therein and, supported in each opening, a hotplate whose top surface closes said opening and prevents spillage from penetrating around edges of the hotplate, wherein each hotplate is supported so that its top surface is flush with the surface of the main panel.
Preferably, at the point where an edge of the main panel meets the edge of the hotplate, the main panel is undeviated. By this is meant that the main panel does not have an up- or down-turned lip, flange or stepped portion, or the like on its edge immediately adjacent the hot plate.
Typically, the main panel is of pressed metal and/or the top surface of each hotplate is defined by a glass ceramic plate.
The invention therefore typically provides a hob having a pressed metal main panel and a plurality of discrete glass-ceramic panels located in liquid-sealed, substantially flush fit relationship to the main panel, the glass ceramic panels meeting the main panel without deviation of the main panel.
Conveniently, an adhesive or a non-setting mastic or the like may be provided between the hotplate and the main panel to aid liquid sealing.
An embodiment of the invention will now be described by way of example only with reference to the accompanying drawings, in which: Figure 1 is a top view of an electric hob; Figures 2 and 3 are respectively sections of the hob with the plates removed and taken on lines A-A and B-B of Fig. 1; and Figure 4 is a section of the hob adjacent one hotplate.
In the drawings, an electric hob 10 comprises four hotplates 12 in corresponding openings 14 in a pressed metal main panel 16. The edges of the panel 16 bounding the openings 14 are in the major plane of the panel. Portions of the panel 16 are downwardly formed to define a pair of combined reinforcement and drainage channels 18 that are generally X-shaped in plan with a common central portion 20 between a respective pair of hotplates 12 and arms 22 that extend from the central portion 20 to partly surround each hotplate 12. The edge of the panel 16 is formed at its boundary edge with a depending flange 24.
Referring now to Figs. 2 to 4, each opening 14 is closed by means of a hotplate assembly 30 having a hotplate 12 of glass-ceramic or similar material that is rebated at 34 so as to fit into and be retained behind the opening 14 with its top face flush with that of the panel 16. A non-setting mastic is provided between plate 12 and main panel 16 to assist in maintaining a liquid-tight seal between them. The assembly 30 includes an electrical heating element 36 beneath the plate 12, a cup-shaped shield 38 of heat-resistant insulating material and an outer cover 40. The assembly 30 is supported by means of a strap 42 of inverted top-hat section whose extremities 44 are attached to bolts 46 welded to and depending from the underside of the panel 16.The central portion of the strap 42 has an upstanding support 48 that threadedly engages in the cover 40 to urge the assembly upwardly into tight engagement with the main plate 16.
1. A hob comprising a main panel having a hotplate opening formed therein and, supported in each opening, a hotplate whose top surface closes said opening and prevents spillage from penetrating around edges of the hotplate, wherein each hotplate is supported so that its top surface is flush with the surface of the main panel.
2. A hob according to Claim 1, wherein the main panel is undeviated at the point where an edge of the main panel meets the edge of the hotplate.
3. A hob according to Claim 1 or Claim 2, wherein the main panel is of pressed metal and has a plurality of hotplate openings, the top surface of each hotplate being defined by a glass-ceramic plate.
4. A hob having a pressed metal main panel and a plurality of discrete glass-ceramic panels located in liquid-sealed, substantially flush fit relationship to the main panel, the glass ceramic panels meeting the main panel without deviation of the main panel.
5. A hob according to any preceding claim, wherein the top edge of the hotplate is rebated so that it fits into the opening in the main panel.
6. A hob according to any preceding claim,
