DE102007060191A1 - Electric steam iron, has water tank provided with tank wall, which is made of air-permeable, water-impermeable membrane, and steam chamber connected to water tank, where membrane is arranged in geodetically overlying region of tank - Google Patents

Abstract

The iron has a heatable ironing base (10), and a water tank (11) provided with a tank wall (12). An air-permeable, water-impermeable membrane (14) is arranged in a geodetically overlying region of the water tank in an operation condition, and is made from a microfiber. A steam chamber (13) is connected to the water tank, and the tank wall is made of the membrane. The tank wall includes a recess that is sealed by the membrane, which is arranged at a geodetic high position over an air chamber (16) of the water tank.

Description

The The invention relates to an electric steam iron according to the preamble of claim 1.

Known electric steam irons include a heatable soleplate and a steam chamber connected to a water tank. For setting the water tank to be introduced into the steam chamber Amount of water is usually provided a steam quantity adjusting device. Especially with steam irons, their water tank is filled from the back However, there may be an adverse overpressure in the water tank when a filling opening closed is. The problem with this is that uncontrolled by this pressure water is pushed into a supply line of the steam chamber.

at known solutions is a pressure relief line provided to avoid this problem. The disadvantage is that this solution easy to install and expensive is.

task The present invention is an improved electrical steam iron in such a way that an overpressure in the water tank is prevented to a defined vapor formation too enable.

These Task is according to the invention with the Characteristics of the main claim solved. Preferred developments emerge from the subclaims.

In an electric steam iron according to the invention, a tank wall is at least partially formed from an air-permeable, watertight membrane. In a particularly preferred further development of this membrane is made of microfiber, particularly from Goretex ^® formed. Through the membrane creates an advantageous pressure equalization, whereby an undesirable pressure in the water tank can be prevented. At the same time, the tank wall is conveniently completely sealed by the membrane. The proposed solution is inexpensive and easy to produce.

In According to a preferred development, the tank wall has at least one Recess which is sealed with the membrane. It can do that be provided that the diaphragm in the operating state in a geodetic top lying region of the water tank is arranged. This will be convenient an additional Sealing against an undesirable Outlet of water provided. Particularly preferably, the Membrane at a highest point above one Air space of the water tank can be arranged, so that a desirable Pressure equalization can take place.

In a further preferred embodiment is the iron an iron with refilling, why this in the rear area an opening to fill having.

The Membrane can be flat be formed and at least on one side, the at least one recess cover. In this embodiment the membrane is lid-like. Conveniently, the membrane glued to the tank wall in an edge region around the recess be. It can also be provided that the recess on both sides is sealed with a membrane, with a first membrane on an outside and a second membrane disposed on an inner side of the tank wall is. The membrane can also be formed double or multi-layered be.

In a variant, the membrane in the manner of a plug in the Be arranged recess. The membrane can be over a Clamp connection and / or a bond to the tank wall connected be.

Based an embodiment shown in the drawing, the invention below described. It shows:

1 a sectional view of a preferred embodiment of an electric steam iron with a preferred membrane; and

2 a detailed sectional view of the sectional view 1 ,

In the figures become the same or substantially the same Elements provided with the same reference numerals.

1 shows to illustrate the invention, a sectional view of a preferred electric steam iron with a heatable soleplate 10 a water tank 11 and one with the water tank 11 connected steam chamber 13 , On a handle 17 The steam iron can be passed over an ironing material. To release steam, water may leak from the water tank 11 in the steam chamber 13 be dosed. There, water is heated quickly to steam and through a steam outlet 18 not shown openings in the soleplate 10 delivered to the outside. The temperature of the soleplate 10 is via a thumbwheel 25 adjustable. A power supply is via an electrical connection 26 ,

For steam regulation is a drip valve 19 provided the water tank 11 with the steam chamber 13 combines. The drip valve 19 includes egg NEN housing-fixed valve seat 20 and a cooperating with this, axially displaceable between two extreme positions valve rod 21 using a compression spring 22 is surrounded. The compression spring 22 rests against a spring seat fixed to the housing. Is the valve rod 21 not pressurized, presses the compression spring 22 the valve rod 21 up. To the valve rod 21 To move down, the spring force of the compression spring must be 22 be counteracted. Depending on the position of the valve stem 21 closes one at the bottom of the valve stem 21 arranged needle 23 an opening of the valve seat 20 , or release them. The position of the valve stem 21 is over one on an upper outer surface of the handle 17 arranged actuator 24 adjustable.

The water tank 11 is via a arranged at the rear end of the steam iron filling opening 27 filled with water in a known manner. The tank wall 12 is at least partially from an air-permeable, waterproof membrane 14 educated.

From the detail section in 2 it can be seen that the tank wall 12 a recess 15 characterized by the preferably formed of a microfiber membrane 14 is sealed. The membrane 14 is flat and covers the recess 15 lid-like on an outer surface of the tank wall 12 from. The membrane 14 is in particular in a geodetically in the operating state overhead area of the water tank 11 arranged, more preferably over an airspace 16 of the water tank 11 , In a preferred embodiment, the membrane 14 with the tank wall 12 bonded.
