  • a fuel filler neck 40 and an exhaust gas outlet opening 41 is further arranged.
  • the water 42 preferably demineralized and decalcified water, is filled into the water tank 2 via a water inlet port 50. From the water tank 2, the water 42 is sucked by an electric pump 3 via a suction line 7 and conveyed via a pressure line 8 to the heater 4 and further to the dispensing devices 24 and 25. Immediately after the pump 3, a switching valve 19 is arranged in the course of the pressure line 8, which directs the water 42 either in the first pressure line section 8b for providing high-pressure hot water 46 or in the second pressure line section 8a for providing dry steam 47.
  • a pressure control device 9 is arranged in the form of a pressure control valve, by means of which the pressure in the pressure line section 8b is set to approximately 120 bar.
  • a pressure control device 9 is also arranged in the form of a pressure control valve, wherein in this second pressure line section 8b for providing dry steam 47, the pressure is controlled to about 30 bar.
  • the pressure line section 8b has two sub-branches, in each of which a flow control device 10, 10 'is arranged in the form of a throttle nozzle. The diameter of the throttle nozzle 10, 10 'defines how much water is fed into the heater 4 per minute. From this amount of water supplied to the heater 4, it depends on whether the produced steam is supplied to the discharge device 25 as wet or dry steam.
  • the two pressure line sections 8a and 8b are then brought together again to form a common pressure line 8 and open into the heating device 4, wherein a flow monitor 12 is arranged in the pressure line 8.
  • the heater 4 is formed in the illustrated embodiment as a fossil fuel 44 operable steam generator.
  • the steam generator in this case has a steam boiler 5 and an oil burner 6.
  • the oil burner 6 is a pump 32nd assigned, which is connected via a suction line 33 and a return line 33 'to the container 31 for the fuel 44 in connection.

  • a safety valve 45 is also arranged.
  • a connecting device 16 for compressed air is furthermore provided, the feeding of the compressed air via the compressed air line 17 into the discharge line 13.
  • a heat exchanger 18, which is fed by the heater 4 is arranged to ensure that the introduced compressed air has at least approximately the same temperature as the dry steam 47, which can ensure that at the dispensing device 25 actually dry steam 47 emerges. If, for example, one were to feed the compressed air into the discharge line 13 without heating, the dry steam 47 located in the discharge line 13 would cool to a temperature below 170 ° and would no longer emerge as wet steam at the discharge device 25.
  • FIG. 3a and 3b Another embodiment is in Fig. 3a and 3b shown. It goes without saying that the cleaning device according to the invention in addition to the illustrated embodiment as a mobile device can also be designed as a standalone device.
  • the boiler pump 3 sucks on the suction line 7 water 42 from the water tank 2 and pumps it via the pressure line 8, in the course of which a check valve is arranged in the empty steam boiler 51. Reaches the water 2 the probe 57 automatically turns on the heater. When the water 42 reaches the probe 58, the boiler pump switches off automatically.

  • Each heating cartridge 52 consists of several heating elements, which are grouped together.
  • the heating device 4 By heating the water 2 51 pressure is built up in the boiler, which can be limited by the pressure regulators 59. When the pressure setpoint or the preset working pressure is reached, the heating device 4 automatically switches off again. Via the pressure indicator 61 it can be seen which working pressure has been reached. When the electric valve 62 is opened, the steam flows via the line 67 into the mixer 63, where, as required, cleaning agent 43 or disinfectant can be supplied by means of the electric pump 56, which can be designed, for example, as an oscillating piston pump. About the plug-in coupling 29, the vapor-cleaning agent mixture thus produced can be performed by means of a steam hose to the execution device 25.
  • compressed air can be supplied via the line 71 to a heat coupling device 72 via the mixing group 68, in which the compressed air is heated by means of steam and then via the plug-in coupling 70 via a pressure-tight hose and the plug-in coupling 53 of the dispensing device 25, which can be designed, for example, as a lance , is supplied.
  • 25 control elements 54 are arranged in the handle of the dispensing device.
  • the allowable working pressure so opens the safety valve 45, so that the pressure can escape. If the boiler pump 3 fails, so that no more water 2 is pumped into the steam boiler 51, the water level falls below the probe 57, whereupon the heating device 4 automatically switches off. If the water 42 in the water tank 2 reaches a minimum level, then a level switch 73 arranged in the water tank 2 switches off the heating device 4. If a minimum level is reached in the detergent container 14, the level switch 74 arranged there switches off the pump 56 automatically in a simple manner.
