The invention relates to an electric stove with heat radiating tubular heating elements that consist of a metal tube, inside which an insulating material is interposed the heating conductor runs. Such heat radiating tubular heating elements for hot plates to use for electric stoves or also for electric grill plates is already known. The! known exposed and, for example, only tubular heating elements carried by a few narrow webs

t arrangements for stoves have the Disadvantage that food that boils over can flow onto live parts, and

> 5 that when cleaning or other handling There is a risk of contact underneath the radiator, since such hot hotplates are more familiar Kind of the tubular heater ends out of the plate level downwards and are connected to the connecting lines below the actual plate. Another The disadvantage of such known designs is that the downward Any other use of the space below the heating pipe level is not possible at the ends of the tubular heating element let come. ·

According to the invention, the ends of the heating pipes, which are located in a space separate from their connection points, lead out of the heating surface and open into a _{completely closed space which is arranged laterally of 11 of} the heating surface and is used to accommodate all lines, switches and terminals in! one side wall of which the ends of the heating pipes are attached, and the space below the heat radiating heating pipes is designed as a grill or preheating space * and can be closed off by a dirt slide designed in the manner of a drawer, the end of which forms part of the front wall of the stove.

The aforementioned space is completely free of live parts in this way. The new design also prevents the same on the terminals and connecting lines when the food overflows got. All connection and accessory parts of the. electrical laying are stored moisture-proof and protected against dirt; further they are also not easily accessible. Furthermore, the easy replacement of the Radiators possible at any time. ^ '

If the lower room is designed as a heating oven, the hotplate can be used at the same time normally be put into operation without the overflowing food causing damage. In this case appears

*) The patent seeker stated as the inventor:

Dr. Friedrich Jor dan in Frankfurt, Main.

it is advisable to attach a special catch plate below the heating pipes which foods that boil over are diverted after the side walls. When training as a grill area, however, no catch plate is used, but the The surface of the heating pipes is best covered by a plate. The stove has two or more hotplates, so can .beim subject of the invention the closed space, which is used to accommodate all cables, switches and connection points through Use of only a single five-step switch, which has a single, parallel and The one-piece heating pipes can be connected in series, and their dimensions are very small being held. So it is possible to supply the full heating power to each heating point individually, furthermore, despite the heating pipes not being subdivided, both heating points together with full Heating capacity and to be heated together with reduced heating capacity.

One of the possible embodiments is shown in the drawing in two figures.

Fig. Ι shows an electric table stove with two heating points seen from the front, partially on average,

Fig. 2 is a view from above. α and b are the heating pipes of the two heating points. The ends c and d of the heating tubes are led out laterally from the heating zone and open into the space e, which is used to accommodate all lines, the terminals / and the switching element g . The heating pipes α and b are supported on supports h which are attached to the stove top i , and are held in the operating position by fastening their ends c and d to the side wall k and / which is attached in the stove. The space m below the heating pipe α or b is completely free of line connections, η is the drawer-like dirt slide, when it is pulled out by means of the handle 0 , part ρ of the front wall of the stove is removed so that the space m is easily accessible for cleaning purposes . A single rotary switch g, which has five switch positions, is used to regulate the heating of both heating pipes, so that, in addition to the switch-off position, the heating pipes α and fr can be switched individually and both simultaneously, in parallel or in series.

Claims (3)
