ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to the field of appliances provided for the care of textile articles such as clothing, by subjecting them to the combined action of a thermal treatment, a mechanical treatment and a steam treatment.
The invention concerns more particularly an electric steam iron having a sole plate containing outlet holes communicating with an evaporation chamber which is heated by means of a heating circuit that is in thermal communication with a temperature regulating or control device, the chamber communicating with a water reservoir through an orifice capable of being blocked by a valve, the valve permitting control of the flow of water from the reservoir into the evaporation chamber.
It is already known in the art to provide such a pressing iron with a removable valve, which offers the advantage of being able to easily clean the valve, and thus counter the buildup of scale.
It is also known to provide a pressing iron in which the valve can be maneuvered by means of a control device to occupy at least one steaming position, in which the valve at least partially opens the orifice connecting the reservoir to the evaporation chamber. An iron having several steaming positions differing as to the rate at which water is admitted into the evaporation chamber offers the advantage of permitting the user to regulate the quantity of steam emitted, in order to adapt it to the more or less creased state of the article or to the nature of the fabric to be ironed. Such an arrangement presents however the drawback of allowing the water to flow through the sole plate holes when the temperature of the evaporation chamber is insufficient to evaporate all of the water admitted into the chamber, for example during ironing of a delicate fabric requiring low sole plate temperatures, and for which the thermostat of the appliance has been set to an assigned low temperature. Such an arrangement also has the drawback of requiring the user to regulate, as a function of the nature of the fabric to be ironed, at the same time the thermostat of the appliance and the quantity of water admitted into the evaporation chamber, in order to prevent drops of water which have not evaporated from exiting through the holes in the sole plate.
BRIEF SUMMARY OF THE INVENTION
An object of the invention is to overcome the above-mentioned drawbacks and to provide a pressing iron having a removable valve in which the water contained in the reservoir is only admitted into the evaporation chamber when the temperature within the chamber is sufficient to permit evaporation of the totality of the water arriving into the chamber.
Objects of the inventions are achieved in a steam pressing iron having, as shown in
FIG. 1
, a sole plate
11
provided with steam outlet holes
12
communicating with an evaporation chamber
14
, the sole plate
11
and the evaporation chamber
14
being in thermal communication with heating means, the evaporation chamber
14
communicating with a reservoir
15
via an orifice
16
capable of being blocked by a valve
17
disposed in a housing
52
. According to the invention, the valve
17
includes a rod
5
capable of blocking the orifice

that is fixed to a bellows
4
forming at least one part of a water tight conduit
31
between the reservoir
15
and the evaporation chamber
14
, the support
3
being capable of being actuated by a bimetallic strip
