Definitions

  • the invention relates to a steam cleaning device with a water storage container heated for evaporation, a steam line emerging from the steam room of the water storage container, which leads to a steam dispensing element and in which a closing or metering valve is arranged and which enters the steam line ⁇ tendency supply for liquid water.
  • Steam cleaning devices of this type are also increasingly being used in the private sector in order to enable effective cleaning of objects and surfaces without the use of chemicals.
  • the cleaning is extremely effective, since a high dissolving effect occurs due to the high temperature of the impinging steam.
  • liquid water to the steam jet to a small extent in order to improve the cleaning effect.
  • Another advantage of the construction described is that the user is independent of a connection to the water supply during operation.
  • the liquid water is taken from the water reservoir as well as the water vapor, so that at the portable steam cleaning device, which is not connected to a water source, both operating modes can easily be carried out.
  • the use of the riser results in a particularly simple construction; if necessary, the riser and the steam line can be led out of the latter through a common opening at the top of the water reservoir, so that such a device can also be used on existing water reservoirs without design changes be used.
  • the steam flow enters the liquid flow vertically in the area of the inlet of the steam pipe.
  • a particularly effective mixing of the medium is achieved in the two states of aggregation.
  • the liquid particles are torn open and distributed evenly in the steam flow, so that a wet steam flow is generated, not a dry steam flow with embedded water droplets.
  • the steam line has a T-shaped line piece, at the opening part of which the steam line emerging from the steam chamber and on the continuous part on the one hand the supply of the liquid water and on the other hand the supply to the steam delivery element Steam line are connected.
  • the metering or closing valve in the Supply of the liquid water is formed by a push button valve which can be moved into the open position against the action of a spring.
  • This valve is therefore normally closed, so that only a dry steam flow is emitted in normal operation. Only in the event that a specially enhanced cleaning effect is necessary can the user achieve the addition of liquid water by operating the pressure-type valve against the action of the spring, and this addition is stopped immediately as soon as the user releases the valve. This contributes in particular to saving water in operation and thereby extending the operating time. In practice, cleaning with dry steam is completely sufficient in most cases; it is only sensible for very extreme soiling to briefly increase the cleaning effect by adding the liquid water.
  • the metering or closing valve is designed as a continuously variable control valve.
  • FIG. 2 shows a cross-sectional view of a water storage container with a riser pipe for use in a steam cleaning device according to FIG. 1.
  • the steam cleaning device comprises a water storage container 1, which is partially filled with water, so that a water space 2 filled with liquid water and a steam space 4 lying above the water level 3 result.
  • a heater 5 which heats the water to such an extent that water vapor is produced under increased pressure in the steam chamber 4, for example the temperature in the interior of the water storage container can be increased to 130.degree.
  • a steam line 6 leads from the steam chamber 4 to a dispensing element (not shown in the drawing), for example to a spray tube or a mixing head.
  • a closing valve 7 is switched into the steam line 6 and can preferably be arranged on the steam dispensing element itself.
  • a riser pipe 8 which plunges deep into the water space 2 and which is connected to a liquid supply line 9 which in turn opens into the steam line 6 upstream of the closing valve 7.
  • a liquid supply line 9 which in turn opens into the steam line 6 upstream of the closing valve 7.
  • This confluence is only shown schematically in the drawing, in fact it preferably takes place in such a way that the steam flow in the steam line strikes a liquid flow in the liquid feed line perpendicularly.
  • a T-shaped line piece can be provided in the region of the mouth of the liquid supply line 9, in the opening part of which the steam line 4 connected to the steam chamber 4 opens, while the liquid supply line 9 is connected to the continuous part on one side on the other side is the steam line 6 leading to the steam delivery element.
  • a metering or closing valve 10 is inserted into the liquid supply line 9 and, in the exemplary embodiment shown, is formed by a button valve which can be actuated by a push button 11. This is located on the outside of a housing 12 of the steam cleaning device surrounding the water storage container 1 and can be pressed in against the action of a spring, which is not shown in the drawing. When pressed in, the metering or closing valve 10 is opened, ie when the push button 11 is released, this valve inevitably goes into the closed position.
  • the metering or closing valve 10 can preferably be a stepless control valve, so that the liquid discharge can be metered into the steam jet.
  • steam is therefore routed from the steam room 4 via the steam line 6 and via the open closing valve 7 to the steam delivery element and discharged from there in the form of a dry steam jet when there is a normal need for cleaning and when the push button 11 is not actuated.
  • the user can briefly open the liquid supply line 9 by pressing the pushbutton 11, and this leads to the high pressure of the steam in the steam chamber 4 causing hot water from the water chamber 2 through the riser pipe 8 in the liquid supply line 9 is pressed.
  • the steam enters the short-term liquid flow from the steam line 6 and thereby forms a homogeneous wet steam mixture, which is then fed to the steam delivery element via the closing valve 7. It is thus possible to press 11 to spray wet steam during the duration of the pressure and thereby increase the cleaning effect in the desired manner.

Abstract

Pour renforcer en cas de besoin l'action de nettoyage d'un dispostif de nettoyage à la vapeur comportant un réservoir d'alimentation en eau chauffé pour produire de la vapeur, une canalisation de vapeur partant de la chambre de vapeur dudit réservoir, menant à un organe de distribution de vapeur et contenant une soupape de fermeture ou de dosage, et une canalisation d'amenée d'eau liquide dans la canalisation de vapeur, ladite canalisation d'amenée est une conduite ascendante (8) plongeant dans la chambre d'eau du réservoir d'alimentation en eau. Une soupape de fermeture ou de dosage (10) est montée dans la canalisation d'amenée qui débouche dans la canalisation de vapeur en amont de la soupape de fermeture ou de dosage située dans cette dernière.
