Embodiment Construction

[0034] A portable steam cleaner, generally designated by the reference number 10 , is shown schematically in the drawing with a housing 12 which has a handle 16 on its upper side 14 . A hose connection 20 , to which a steam outlet hose 22 can be connected, is arranged on the front side 18 of the housing 12 . A steam outlet nozzle can generally be connected to the free end of the steam outlet hose 22 (not shown in the figures). Alternatively, a rigid extension can be connected to the free end of the steam outlet hose 22 , to which in turn a steam outlet nozzle, in particular a floor nozzle, can be connected. Such extension pipes and steam outlet nozzles are known to those skilled in the art.

[0035] Above the hose connection 20 , a liquid container 24 is arranged on the housing 12 , which can be removed from the housing 12 and can be filled with cleaning liquid, preferably water. as by Figure 4 It is clearly shown that the housing 12 surrounds an electrically heatable stea...

Abstract

The invention relates to a steam cleaning device (10), comprising a liquid tank (24), which is connected to an electrically heatable steam boiler (26), wherein the steam boiler has a safety valve (38), which opens at an impermissibly high steam pressure in the steam boiler (26). In order to further develop the steam cleaning device (10) in such a way that the danger of the user being adversely affected by steam exiting through the safety valve (38) is reduced and the handling of the steam cleaning device is simplified, the safety valve (38) is integrated into a detachable maintenance closure (36) and can be covered by a covering element (54), which can be moved back and forth between a closed position that covers the maintenance closure (36) and an uncovering position that uncovers the maintenance closure (36).

Description

technical field [0001] The invention relates to a steam cleaner with a liquid container connected to an electrically heatable steam generator for generating steam that can be applied to the surface to be cleaned, wherein the steam generator has a safety valve , the safety valve opens if an impermissibly high steam pressure develops in the steam generator. Background technique [0002] Such steam cleaners are used for cleaning a variety of different surfaces, especially for cleaning hard surfaces. They include electrically heatable steam generators for vaporizing liquid cleaning agents, in particular water. The generated steam can be applied to the surface to be cleaned, eg to the floor. [0003] For safety reasons, the steam generator has a safety valve which opens when an impermissibly high steam pressure builds up inside the steam generator. [0004] If the steam cleaner does not work with distilled water, then the water base will be deposited in the steam generator dur...
