Therefore, the two connection ends 19A, 19B of the second heating resistor 19 protrude outside the casting of the rear side of the heating body 13, and the second heating resistor 19 starts from the two connection ends 19A, 19B along the Ω The shape extends forward.

The difference between the second embodiment and the first embodiment is that, in the second embodiment, there is neither a pyramid-shaped column nor a blocking wall on the bottom wall 21 . This configuration has the advantage of being simple to implement. However, such elements can also be present on the bottom wall.

Of course, the invention is by no means limited to the embodiments shown and described, which are given by way of example only. Modifications can be made without departing from the scope of protection of the present invention, in particular with regard to the construction of the different elements or by substitution of technical equivalents.

Thus, in an embodiment variant not shown, the water can be injected dropwise into the evaporation chamber through a cock which is fed with water from the container by gravity rather than by a pump.
