Definitions

  • the invention relates to an electric steam iron with an electric switch and a valve.
  • a generic steam iron is known from EP-PS 0 117 852.
  • This known iron has a pump that conveys water from a water tank via a supply line into the evaporation chamber. The inflow into the evaporation chamber is controlled by a valve.
  • An electric switch is arranged in the iron handle, which switches the pump on and off.
  • a valve under spring pressure is arranged inside the valve, which can be moved vertically by means of a manually operable button and a slide rod. To control the valve, the slide is moved vertically via the button, the electrical switch coming into contact with the actuation button and switching the pump on and off.
  • a disadvantage of this device is the multi-part design, which means that assembly is quite complex since the switch must also be adjusted after it has been installed. The adjustment is very difficult, because to control the valve the slide only has to perform a very small stroke and the pump delivery should start before the slide is in the appropriate position Position. In addition, the switch is not protected against moisture and therefore does not meet the prescribed standard for electrically heated steam irons.
  • the object of the invention is to provide a push button valve unit for an electric steam iron, which does not have the disadvantages described above, which can be mounted easily and without special adjustment in the iron handle, and the electric push switch is reliably protected against moisture.
  • the key switch is arranged in a moisture-proof housing.
  • the push button switch is actuated via an elastically deformable membrane, which at the same time seals the switch housing tightly from the outside.
  • the valve housing is sealed by an elastically deformable membrane, the membrane being operatively connected to the switch housing.
  • the valve cone is lifted from its seat via the diaphragm and the movable plunger and the inflow to the consumer is controlled via the valve.
  • the return movement of the Pushbutton valve device in the starting position takes place by means of a compression spring. Due to the inventive design of the membranes, both of which are elastically deformable, and the movably arranged tappet within the valve, only a small pressure force is required to actuate the push-button valve unit, since frictional forces from sliding seals do not occur. Since the actuating force for actuating the key switch is less than the force for actuating the valve, the electrical pulse for the pump is advantageously triggered first and then the valve is actuated. Pushbutton switches and valve are advantageously designed as a related component that can be easily installed in an iron or replaced if necessary.
  • the electrical switch valve unit 1 shown consists of an electrical key switch 3 and a valve 2, which are arranged axially one behind the other.
  • the pushbutton switch 3 is arranged in a housing 6 consisting of a lower part 4 and an upper part 5, which is sealed to the outside by an elastically deformable membrane 7.
  • the switch housing 6 is arranged axially displaceably on the valve housing 8.
  • the valve housing 8 has a valve inlet 9 and a valve outlet 10.
  • Inside the valve housing 8, an insert 11 is provided in which a valve tappet 12 is movably guided.
  • the insert 11 has a valve seat 14 for a valve cone 13 which is under spring pressure.
  • the insert 11 has an annular groove 20, as a result of which the valve outlet 10 can be provided at any desired point on the circumference of the valve housing 8.
  • valve housing floor 21 On the valve housing floor 21 one or more nozzle-shaped valve inputs 10 are provided.
  • a plurality of pushbutton valve units 1 are also built on a valve housing base 21, which have a common valve input 9 but separate valve outputs 10 or, in addition to the valve input 10, further step-shaped outputs are provided on the housing base 21 in order to supply several Allow push button switch units 1 in series.
  • the valve housing 8 is sealed by an elastically deformable membrane 15.
  • a pressure socket 17 is formed on the switch housing lower part 4 and is operatively connected to the membrane 15 of the valve housing 8.
  • the key switch valve unit 1 is held in an iron housing 18.
  • the pushbutton switch 3 If a slight axial pressure is exerted on the actuating button 19 by hand, the pushbutton switch 3 generates an electrical pulse which controls an electric pump, not shown, via electronics, not shown. At the same time, the push button switch housing 6 moves downwards. This vertical stroke movement is transmitted to the diaphragm 15 and the movable plunger 12 to the valve cone 13 via the pressure port 17. The valve cone 13 lifts. thereby from the valve seat 14 and releases the valve outlet 10 to the supply lines, not shown, of the consumers. If the actuating button 19 is relieved of the axial pressure, the pushbutton switch valve unit is brought into its starting position by means of compression spring 16, restoring forces of the membranes 7 and 15 and the restoring force of the pushbutton switch 3.
