Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric steam iron having an electric switch and a valve.

[0002]

BACKGROUND OF THE INVENTION A steam iron of this type, known from EP 117852, has a pump which pumps water from a water tank via a supply conduit into an evaporation chamber. To do. The inflow to this evaporation chamber is
It is controlled via a valve. An electric switch is arranged in the iron grip to turn the pump on and off. A spring-loaded slider is arranged inside the valve, and the slider is vertically slidable via a push switch manually operable and a slider rod.

To control the valve, the slider moves vertically through a push switch. At this time, the electric switch is connected to the operation push switch to switch the pump on and off.

A drawback of such known devices is that they consist of several parts. As a result, the assembly is extremely troublesome. This is because the switch has to be repositioned additionally after it has been assembled. This position adjustment is extremely difficult. This is because the stroke that the slider has to take to control the valve is very small and the pump feed must already be started before the slider can reach its corresponding position. Furthermore, the switches provided in the known device are not moisture-proof, which makes them incompatible with the defined standards for electrically heated steam irons.

[0005]

SUMMARY OF THE INVENTION The object of the invention is to improve an electric steam iron of the type mentioned at the outset, in order to avoid the abovementioned disadvantages and to facilitate it without any special adjustment of the iron grip. It is an object of the present invention to provide a push switch / valve unit used for an electric steam iron which can be assembled and whose electric switch is provided with a moisture-proof means.

[0006]

In order to solve this problem, in the structure of the present invention, the electric switch and the valve are arranged above and below each other in the axial direction, and the switch and the valve are operatively connected to each other. The switch and the valve are operated by different operating forces.

[0007]

According to the present invention, the valve can be controlled at the same time when the electric push switch is operated, based on the axial arrangement of the push switch and the valve according to the present invention. The push switch is arranged in a casing in a moisture-tight manner. This push switch is operated via an elastically deformable diaphragm. At the same time, this diaphragm tightly closes the switch casing to the outside. The valve casing is tightly closed by an elastically deformable diaphragm, which is operatively connected to the switch casing. Between the diaphragm and the valve cone there is arranged a valve tap which is freely movable in the vertical direction or which is rigidly mounted on the diaphragm. When the electric push switch is operated, an electric pulse is formed, which pulse controls the electric pump via the electronic device. At the same time, the switch casing moves vertically downward. This causes the valve cone to be lifted from the valve seat via the diaphragm and the movable valve butter rod, thereby controlling the flow through the valve into the consumer. The return movement of the push switch / valve unit to the starting position is performed by the compression spring. Due to the fact that both diaphragms, which are both elastically deformable, are constructed as in the present invention and that the valve tap is movably arranged inside the valve, it is necessary for operating the push switch / valve unit. The pressing force applied is small. This is because no frictional force is generated by the sliding seal. Advantageously, the operating force for operating the push switch is smaller than the force for operating the valve, so that first an electrical pulse for the pump is emitted and then the valve is operated. Advantageously, the push switch and the valve are constructed as one integral component, which can be installed without problems in the iron or replaced if necessary.

[0008]

Embodiments of the present invention will be described in detail below with reference to the drawings.

The illustrated electric push switch / valve unit 1 comprises an electric push switch 3 and a valve 2, which are arranged one behind the other when viewed in the axial direction. There is. The push switch 3 is arranged in a switch casing 6 consisting of a lower part 4 and an upper part 5. The switch casing is tightly closed to the outside by an elastically deformable diaphragm 7. The switch casing 6 is arranged along the valve casing 8 so as to be slidable in the axial direction. The valve casing 8 has a valve inlet 9 and a valve outlet 10. An insert 11 is provided inside the valve casing 8. A valve stick 12 is movably guided in this insert. The insert 11 has a valve seat 14 used for a spring-loaded valve cone 13.
The insert 11 has an annular groove 20. As a result, the valve outlet 10 can be provided at any desired location on the circumferential surface of the valve casing 8. Valve casing bottom 21
A valve inlet 9 in the form of one or a plurality of pipe pieces is provided in the. However, it is also conceivable that a plurality of push switch / valve units 1 are provided on one valve casing bottom 21. In this case, these push switches
The valve unit has a common valve inlet 9 and a separate valve outlet 10 or the valve casing bottom 21 is provided with another staged outlet besides the valve inlet 9. Thereby, water can be continuously supplied to the plurality of push switch / valve units 1. The valve casing 8 is tightly closed by an elastically deformable diaphragm 15. On the lower part 4 of the switch casing, the pressing tube piece 1
7 is integrally molded. This pressing piece is operatively connected to the diaphragm 15 of the valve casing 8. The push switch / valve unit 1 is held by the iron casing 18.

When a slight axial pressure is applied to the operation button 19 by hand, the push switch 3 forms an electric pulse. This pulse controls an electric pump (not shown) via an electronic device (not shown). At this time, the switch casing 6 simultaneously moves downward. This vertical stroke movement is transmitted to the diaphragm 15 via the pressing tube piece 17 and further to the valve cone 13 via the movable valve stick 12. This causes the valve cone 13 to lift from the valve seat 14 and open the valve outlet 10 leading to the supply conduit (not shown) of the consuming device. When the pressure in the axial direction of the operation button 19 is reduced, the push switch / valve unit moves to the compression spring 16
And the returning force of both diaphragms 7 and 15 and the returning force of push switch 3 bring them to the starting position.
