Electrically operated steam generator

The innovation relates to an electrically operated steam generator with automatic shutdown after Optionally selectable duty cycle for heating objects, consisting of an insulating material manufactured housing lower parts with heating device, a carrier insertable in this for the to be heated Objects and an attachable upper housing part made of insulating material.

Known devices of this type have under the bottom of the pot receiving the objects to be heated electric heating coil adapted to the shape of the floor, depending on the voltage with which the device is operated should be made of more or less strong resistance wires. The heating resistance wires which are insulated from the housing, the heat goes to those to be heated by radiation and partial convection

The switch-off after the preselected evaporation takes place in the simplest way, since the liquid level sinks ao far, that "umindeat" in · the electrode no longer comes into contact with the liquid. Any safeguards against "Xroeken" are not necessary, as the device stops after the liquid has evaporated and damage cannot occur even if the device is dry. For operational safety, the contact protection according to the invention is Torgesenen, which can also be supplemented by wall separation from the Hetz, in that the supply line to the electrodes can be separated by a plug connection with the upper and lower parts

or by the fact that the upper part echoes when it is placed on the lower part. Another possibility is that the contact protection plate is earthed and thus even if the device is accidentally switched on, the liquid exceeding the contact cover plate cannot assume a potential that could endanger the operator. The upper and lower parts of the steam generator according to the invention are locked _{9 in} this way, steam shut-offs τοη over 100 qin of well-known feioe can be achieved, which means that "gentle and quick preparation of food is improper"
