Description

Electric heating and cooking device Addendum to patent 680335 The patent 68o335 describes an electric heating and cooking device in which the vessel used to hold the heating medium is surrounded by the steam space of a water chamber provided with electrodes and in which the electrodes are in the water chamber are arranged in such a way that the performance of the device remains completely or almost constant when the water level inclines caused by fluctuations in the means of transport. For this purpose, the electrodes are designed as cylinders arranged concentrically one inside the other and to the axis of the electrode space, the jacket of which is provided with evenly distributed openings, and in the normal position of the device the electrodes are only part of their height, approximately at 3, covered by the water to be evaporated. The purpose of this arrangement is to make such devices suitable for use on ships or similar means of transport subject to fluctuations, to achieve unclean at least approximately constant power consumption in every position that the boiler can assume during operation.

The arrangement described in patent 680335 has been shown to work satisfactorily as long as the cooking appliance is tilted about its vertical axis. When operating the device on ships or similar means of transport, however, the case very often occurs that the cooking device is not only tilted around its vertical axis, but also executes movements around a vertical axis lying outside the device under the influence of the fluctuations in the means of transport. Such fluctuations is the arrangement described in patent 680 335 tion has not grown because it is in a such trap the electrolyte in a F the water chamber collects and dad @ R the one in the middle of the water chamber. o @ @@ advised electrodes can be completely exposed, -To avoid these disadvantages of the arrangement described in patent 68o335, according to the present invention in the water chamber arranged concentrically to one another, cylindrical electrodes are distributed approximately evenly over the entire transverse step of the water chamber, and furthermore the Height of the individual electrodes from the inside to the outside in a step-like manner.

In the drawing, an embodiment of the inventive concept is shown schematically, namely Fig. I illustrates a partial elevation of the device in section, while Fig. A shows a plan view in section along the line AB. The parts of the device which are superfluous for explaining the invention are omitted and the designations are chosen so that they correspond to parts of the patent 680335 of the same type.

With i to 3 the three electrodes are referred to as they are in use of Dmehstrom are required. Those in the water chamber are concentric to each other , arranged cylindrical electrodes are approximately, evenly over the whole Cross-section of the water chamber distributed io, and furthermore the height of each increases: Electrodes 1, z, 3 from the center outwards in a step-like manner. The electrodes larger area, for example the outer i and. the middle z are again with recesses q. provided to at least .approximately equal areas of the electrodes 1, a and 3 to get Lund as a result: an equally large current load of the individual To achieve electrodes.

The outer boiler of the device is designated by 16, while at 1; 5 the steam tube and at 9 the inner boiler for receiving the food is indicated. At 13, the connecting pipe between the water chamber and the receiving vessel , not shown, of the patent 680335 is shown.

The water chamber is only filled with the electrolyte to such an extent that the electrodes are only partially covered by it at their height. The electrolyte is filled in, for example, up to the line e indicated by dashed lines. If the cooking appliance is now exposed to fluctuations about a vertical axis lying outside the appliance, it increases , 1) for example the electrolyte that is used by the line b, also shown in dashed lines, @ Clear location within the water @: iä2er a. From Fig. I can be seen clearly; "that even then the electrode surface covered by the electrolyte is at least approximately as large as before in the normal position of the cooking appliance.

Inside and / or outside the water chamber, baffles are i i arranged, which have a substantially circular shape and parallel run to the horizontal axis of the cooking appliance. The baffles have the purpose a sloshing around: the electrolyte caused by the fluctuations of the cooking appliance should be avoided as far as possible.
