## Abstract

The invention relates to a steam iron comprising a water tank 1 and an evaporation chamber 13, the water supply from the water tank to the evaporation chamber being effected via an electric pump 2, whose operation is dependent upon the water level in a reservoir 3 provided in the water supply between the pump and the evaporation chamber.

## Claims

### Claim 1

A steam iron which comprises:
an evaporation chamber;
a pump for supplying water from a water tank to said evaporation chamber; and
a pressure reservoir which is provided between said pump and said evaporation chamber, wherein the operation of said pump is controllable between on and off modes as a function of an amount of water in said pressure reservoir.

### Claim 2

A steam iron which comprises:
a water tank;
a controllable electric pump which is connected to said water tank, and an evaporation chamber which is supplied with water via valve-controllable supply lines, wherein the water supply from said water tank to said evaporation chamber is effected by said pump, and wherein at least one pressure reservoir is disposed between said pump and said evaporation chamber, and further wherein an electric switch is in operative connection with said pressure reservoir, wherein said electric switch switches said pump on or off as a function of the level of filling of said pressure reservoir with water.

### Claim 3 (depends on 2)

The steam iron of claim 2, wherein the quantitative measuring of an amount of steam is effected by driving said pump via an electronic pulse circuit.

### Claim 4 (depends on 2)

The steam iron of claim 2, further comprising;
a spray device which is activated by a manual actuation member and which is controlled via a first cutoff valve.

### Claim 5 (depends on 4)

The steam iron of claim 4, wherein the quantitative measuring of an amount of steam is effected by driving said pump via an electronic pulse circuit.

### Claim 6 (depends on 4)

The steam iron of claim 4, wherein said water tank, said pump and said pressure reservoir are connected to at least one of said evaporation chamber, an auxiliary steam chamber and said spray device via a system of supply lines.

### Claim 7 (depends on 6)

The steam iron of claim 6, wherein the quantitative measuring of an amount of steam is effected by driving said pump via an electronic pulse circuit.
