Abstract

A gas hob comprises a casing 2 in the form of a shallow tray with a spill plate 4 extending across the top, the latter carrying one or more pan supports 15 and having openings through which two or more burners 6 project, and pipes 12, for conveying gas to the burners, located between the spill plate 4 and the base of the casing 2 and extending into the sides of the burners 6. A hob of this construction can be made with an overall height of less than 65mm so as to be suitable for mounting on a work surface of standard height without raising the pan supports to a level which makes them inconvenient to use. <IMAGE>

Description

SPECIFICATION Gas hotplates This invention relates to gas hotplates incorporating a plurality of burners and associated controls. Such hotplates as have been constructed hitherto com- monly have a height ofthe order of 1 00mm or more, and are designed to be fitted into openings in worktops. Howeverthis is notalwaysconvenient.

According, therefore, to the present invention a gas hotplate comprises a sheet metal casing, a spill plate extending across the top of the casing and provided with openings through which two or more burners project, pan supports carried by the spill plate and, between the spill plate and the base of the casing, pipesforcarrying gas and airtothe burners, the pipes extending into the sides ofthe burners. With this construction the hotplate can be made with an overall height, from the base to the level of the pan su pports, of less than 65mm, and such a hotplate is suitablefor mounting on top of a working surfaceof standard height, without raising the pan supports to a level which makes them inconvenient to use.

The casing is conveniently in the form of a shallow tray with upturned sides, with the spill plate secured to the upper edge ofthe tray.

The hotplate may in some cases incorporate a hinged cover having a closed position in which itex- tends across the top of the casing, and being capable of being pivoted upwards into an open position to provide access to the burners.

Two hotplates in accordance with the invention will now be described by way of example with reference to Figures 1 to 4 ofthe accompanying schem aticdrawings, in which Figures land 2 represent a plan view and a front view in part section ofthefirst hotplate, and Figures 3 and 4 represent a plan view and side viewofthesecond hotplate.

The hotplate illustrated in Figures 1 and 2 comprises a mounting box 1 in the form of a rectangular metal tray with a flat base 2 and side walls 3 having a depth ofapproximately30mm.

Across the top ofthe mounting box extends a sheet metal spill plate 4 having a shallow rectangular depression 5 and pierced by four circular openings through which extend respective burners 6, the lower ends of which lie within the mounting box. A raised platform 7 adjacent a side edge of the assemblyprovidesa coverforthegastaps8con- trolling the supply of gas to the burners 6, the taps having upwardly extending spindles 9 projecting through the cover and carrying control knobs 10 at their upper ends. Outlet pipes 11 from the taps 8 extend into respective burners tubes 12 leading into the sides of the bodies 13 of individual burners. The burner bodies 13 are fitted with caps 14 in known manner.Each pair of burners is associated with a pan support 15, the supports being disposed side by side within the depression 5 in the spill plate 4, with their upper surfaces slightly above the burner caps 14, in the usual way.

By arranging forthe burnertubes 12 to extend into the sides ofthe burner bodies 13thetotal depth of the hotplate can be kept below 65mm, the hotplate being suitableformounting on aworkingsurface withoutthe pan supports 15 being at an inconvenient high level.

The hotplate illustrated in part in Figures 3 and 4 is similar to that of Figures 1 and 2 exceptthatthe cover 7 for the taps 8 is disposed at the front ofthe hotplate, and is at a lower height than that of the first embodiment. In addition it has an inclined front surface 16, and thetaps 8 are disposed so thattheir spindles 9 project forwardly through this surface, the control knobs 10then being located atthefrontofthe plate, as shown.

Ignition ofthe burners is conveniently by means of a push-button operated spark ignitor (not shown).
