  • the invention relates to a steam cleaning device for cleaning surfaces, especially hard surfaces, with a water reservoir, an electric pump, an electrically heatable steam generator and a steam outlet nozzle.
  • Such steam cleaning devices are used in particular in the household.
  • water can be supplied to the steam generator by means of the electric pump which evaporates within the steam generator and the generated Steam can reach the surface to be cleaned via the steam outlet nozzle be applied.
  • EP 1 059 487 A2 describes the use of a mechanical decalcification device proposed for the steam generator, so that this in regular Time intervals can be mechanically decalcified.
  • the appropriate design The steam generator is associated with considerable costs.
  • Object of the present invention is to provide a steam cleaning device of the above so-called type in such a way that it is both in normal operation as well as when descaling easy handling.
  • the auxiliary pump designed as a piston pump.
  • a check valve is arranged and the electric pump, the check valve and the Auxiliary pump bypasses, wherein the check valve, the flow connection between the auxiliary pump and the electric pump releases, if the fluid pressure in the area between the auxiliary pump and the check valve one exceeds specified value.
  • Such a configuration has the advantage that the liquid flowing through the auxiliary pump is basically only in Passage direction of the check valve can flow. This is when descaling the case, because then the liquid from the water reservoir over the Check valve and the auxiliary pump to the water heater and then flows to the steam outlet nozzle. In normal operation of the steam cleaner the water is supplied by means of the electric pump to the steam generator.
  • the Electric pump bypasses the auxiliary pump and the upstream of the Auxiliary pump arranged check valve.
  • the Electric pump bypasses the auxiliary pump and the upstream of the Auxiliary pump arranged check valve.
  • blockage of the Steam generator or the steam outlet nozzle acts by means of the active Electric pump generated water pressure on the auxiliary pump on the check valve, and when a predetermined maximum value is exceeded the check valve, the flow connection between the auxiliary pump and the electric pump free.
  • the electric pump is operated in circulation mode, by the water from the electric pump via the auxiliary pump and the Check valve is passed back to the electric pump.
  • the check valve thus assumes the function of a safety valve.
  • the check valve may for example comprise a valve body, the is made of a rubber material or an elastomer and when exceeded a predetermined pressure at the outlet of the check valve the Flow connection between the outlet and the inlet of the check valve releases.
  • a particularly simple handling of the steam cleaning device can thereby be achieved that it comprises a switching element for controlling both the electric pump and the steam generator.
  • This has the advantage that the User in normal operation of the steam cleaning device only a single Actuate switching element to clean a surface by steam can. An incorrect operation of the steam cleaning device is thereby avoided.
  • the electrical switching element is an actuating element is assigned to the outside of a housing of the steam cleaning device is arranged.
  • the actuator may, for example, a to the Housing hinged pivot lever have.
  • the used auxiliary pump is by means of an actuator operated by the user. It is advantageous if the actuator is arranged at a distance from the actuating element, which is connected to the electrical Switching element cooperates. By the distance between the actuator and the actuator reduces the risk that a User when descaling the steam cleaner by mistake using the Actuator actuates the electrical switching element and thus the Electric pump and the steam generator turns, instead of the auxiliary pump to put into operation by means of the actuator.
  • the Steam cleaning device has a handle and that with the electric Switching element cooperating actuator disposed on the handle is, and that the actuator arranged at a distance from the handle is.
  • the handle By means of the handle, the steam cleaning device can easily be worn on the handle, the actuator to control the electric pump and the steam generator is arranged.
  • the actuator of the auxiliary pump In the distance to Handle, for example laterally on a housing body of the steam cleaning device, the actuator of the auxiliary pump is positioned so that the User must change his grip position if he is in departure from normal operation the steam cleaning device for descaling the auxiliary pump by means of the actuator would like to put into operation.
  • FIGs 1 and 2 is a generally occupied by the reference numeral 10 Steam cleaning device according to the invention shown, the one of two half-shells finished housing 12 and a water reservoir 14, which is detachably connectable to the housing 12.
  • a snap connection arranged for use with the side of the water reservoir 14, pivotable locking tongues 16 and arranged on the housing 12 locking projections, which can be engaged behind by the locking tongues 16.
  • To fill up can the water reservoir 14 separated from the housing 12 and over a filling opening 18 are filled with water.
  • the filling opening 18 is can be closed watertight by means of a stopper 20.
  • the housing 12 houses an electric pump 22 and a manually operated Auxiliary pump 24 and in addition a steam generator 26 and carries in his the water reservoir 14 facing away from the upper end of a Steam outlet 28. Via a suction line 30 can the water reservoir 14 water are removed, via the branch lines shown in Figure 3 32, 34 both the electric pump 22 and the auxiliary pump 24 is supplied can be.
  • FIG. 2 shows the flow connections used in the form of various hose lines to achieve a better overview only partially shown.
  • a connecting line 36 leads over a first check valve 38 shown in Figure 3 to a water inlet 40 of the steam generator 26.
  • the water evaporated, so that a steam outlet 42 and an adjoining Output line 44 steam supplied to the steam outlet nozzle 28 can be, from the steam generated on the surface to be cleaned can be applied.
  • the branch line 34 branches off from the suction line 30, which establishes a flow connection between the suction line 30 and the Auxiliary pump 24.
  • a second check valve 46 is connected in the branch line 34.
  • the auxiliary pump 24 is connected via a connecting line 48 with the connection line 36 in connection.
  • the auxiliary pump 24 is designed as a manually operated piston pump, wherein the actuation of the auxiliary pump 24 by means of an outside of the housing 12 of the Catching tongue 16 of the water storage tank 14 adjacent arranged Push button 50 can be operated.
  • the electric pump 22 is not shown in the drawing, in itself known electrical cables with an electrical switching element 52 in conjunction, to that also the electrically heatable steam generator 26 via corresponding Electric cables is connected.
  • the electrical switching element 52 in turn is connected to a connecting cable 54 in electrical connection, with the aid of which the steam cleaning device 10 is connected to a supply voltage can be.
  • the housing 12 has an accessible through the user opening 58 and forms a handle 60, disposed in the region of the pivot lever 56 is and can be taken by the user to hold the device.
  • the push button 50 with the aid of the auxiliary pump 24 can be actuated, at a considerable distance from the pivot lever 56th arranged.
  • the user may by pivoting the pivot lever 56 at the same time the electric pump 22nd and activate the steam generator 26.
  • This has the consequence that by means of Electric pump 22 water from the water reservoir 14 via the suction line 30, the branch line 32 and the connecting line 36 to the steam generator 26 can be supplied, where the water is evaporated, so that the generated steam via the output line 44 and the steam outlet nozzle 28th can be issued.
  • the steam cleaning device 10 If the steam cleaning device 10 to be decalcified, so it is only this required to fill the water reservoir 14 with a descaling solution and then the auxiliary pump 24 by means of the push button 50 to while the electric pump 22 and the steam generator 26 are turned off are.
  • the decalcifying solution can then via the suction line 30, the Branch line 34 and the connecting line 48 in the cold steam generator 26th filled and promoted on this up to the steam outlet nozzle 28.
  • the water reservoir 14 can then be refilled with water, and after a certain exposure time, the decalcifying solution by again Actuating the auxiliary pump 24 from the steam generator 26 and the Steam outlet nozzle 28 are driven out. After the descaling can then the electric pump 22 and the steam generator 26 again in operation be set.
