Problems solved by technology

[0011] But for evaporating tap water, especially in a cooking appliance, the aforementioned steam generator does not work satisfactorily and has the serious disadvantage that dissolved minerals contained in the tap water, especially calcium, are deposited on the surface of the steam generator. walls and interior
This can lead to failure or damage to the steam generator, which can usually only be prevented by regular chemical decalcification
The resulting necessary re-operation maintenance work is again expensive

Embodiment Construction

[0115] FIG. 1 shows a simplified diagram of a heatable housing 1 according to the invention. The housing 1 is substantially tubular and has a wall 3 . Wall 3 surrounds an interior 5 . A large number of recesses in the form of holes 7 are formed in the wall 3 . As can be seen in particular from FIG. 1 , the holes 7 pass completely through the wall 3 of the housing 1 along the entire longitudinal axis of the housing 1 . At the same time the holes 7 extend substantially parallel to the surface of the wall 3 facing the interior 5 .

[0116] As can be seen in particular from FIG. 2 , which shows a side view of the housing 1 in direction A in FIG. 1 , the holes 7 are regularly distributed along the circumference of the wall 3 . In particular, the housing 1 has 18 holes 7 , ie the angular spacing α between the individual holes 7 is approximately 20°. When the housing 1 is inserted as a kettle into a steam generator, the housing 1 can, for example, have the following dimensions. ...

Abstract

The invention relates to a heatable housing for a device for producing steam, with at least one wall that delimits an interior space, which is enclosed by the housing at least in areas and which serves to hold a liquid to be vaporized. The wall has at least one recess for accommodating at least one heating device. The invention also relates to a device comprising an inventive housing, and to a cooking appliance for producing steam with such a device.

Description

technical field [0001] The invention relates to a heatable housing for a device for generating steam, the housing having at least one wall defining an inner cavity at least partially surrounded by the housing for containing a liquid to be evaporated; the invention also relates to a A device for generating steam and a cooking appliance having such a device. Background technique [0002] Conventional steam generators, as they are used in particular in cooking appliances, usually have a water pot, which is partially filled with water, which boils through a heating body. The space requirement of such a steam generator is mainly determined by two factors, namely firstly by the volume fraction filled with liquid water and secondly by the volume fraction of the gas chamber located above the water. [0003] The first volume is defined by the dimensions of the heating bodies and the space required between the heating bodies for flushing around them and for carrying away steam bubble...
