Definitions

  • the present invention relates to an electric steam iron according to the preamble of claim 1 and a valve for such a steam iron, wherein the steam iron has a water tank for receiving water with a tank vent for venting the water tank having a valve with a valve body mounted in a valve body , which rests sealingly on a valve seat when filling the water tank and thus controls the tank ventilation, wherein at maximum filling a cavity is formed in the water tank and at least in a vertical rest position of the steam iron, the tank ventilation is turned on.
  • Known electric steam irons have a heatable sole, a water tank for holding water, and a steam chamber operatively connected to the sole and the water tank for generating and storing water vapor.
  • a steam chamber operatively connected to the sole and the water tank for generating and storing water vapor.
  • a travel steam iron which has a valve for opening and controlling the tank filling a water tank, wherein the valve comprises a valve housing in which a valve seat is formed and a valve body is mounted.
  • the valve 10 is arranged in a front region of the water tank 4 remote from the filling opening and has a valve housing 14 with a fluid opening 16 and a connecting piece 18 for connecting the venting line 12. Between the fluid opening 16 and the connecting piece 18, a valve seat 20 is formed.
  • the valve housing 14 has a cross-section widened housing portion 22 which defines the fluid opening 16 frontally, a cross-section tapered housing portion 26 for forming the connecting piece 18 and between these two housing sections 22, 26 arranged cone-shaped transition section 28, on the inner circumference of the valve seat 20 is formed.
  • a ball-like valve body 30 is arranged, which preferably consists of a metallic base material and alone due to its weight in abutment with the valve seat 20 can be brought.
  • the object of the present invention is to provide an electric steam iron which overcomes the aforementioned drawbacks and which, when heated in a vertical rest position, reliably prevents water leakage from the water tank, as well as to provide a valve for such a steam iron.
  • An electric steam iron has a water tank for holding water and a tank vent for venting the water tank.
  • the tank vent has a valve with a valve body mounted in a valve body, which rests sealingly when filling the water tank to a valve seat and thus the tank venting is heading.
  • a cavity is formed at maximum filling in a front region of the water tank and turned on the tank ventilation.
  • the valve has a Fluido réelle, which projects into the vertical rest position in the cavity. The positioning of the Fluido réelle in the cavity prevents that when heating the steam iron on the opened valve water can flow into the tank vent.
  • Pressure equalization takes place directly between the air in the cavity and the air of the outside environment. As the steam iron heats up, the waterline can rise without the risk of water leaking out of the tank vent as the fluid vent protrudes far into the cavity.
  • the Fluido réelle is formed by a tubular air passage, which is in fluid communication with a remote from the Fluido réelle breakthrough of the valve housing.
  • This allows at least the sections circumferentially integration of the air duct in the valve housing, whereby the valve is compact executable.
  • the air duct extends in or nearly in the vertical direction of the parked in his vertical rest position steam iron.
  • the compactness of the valve can be increased if the air duct and the valve housing have approximately the same lengthwise extension.
  • the opening is formed in a section of the valve housing that widens in cross-section with respect to an opening cross-section of the valve seat.
  • the cross-sectional widening of the valve housing is used in particular for receiving the valve body in the vertical rest position of the steam iron and allows a trouble-free pressure equalization of the steam iron during heating, since the valve body is arranged virtually outside a forming during pressure equalization flow path in the valve.
  • the opening is preferably formed circumferentially in the valve housing. In this way, the air channel can be closed at its end remote from the fluid opening end portion together with the cross-sectional widened valve housing portion of a single end-side closure element.
  • the tank vent is designed such that in about or in a horizontal position of the steam iron air over the tank vent between the water tank and the outside environment can be replaced. Accordingly, the breakthrough is so circumferentially arranged in the valve housing or has such a cross-sectional area that it can not be controlled by the valve body.
  • An inventive valve for opening and closing a tank ventilation of a water tank of an electric steam iron with a valve housing in which a valve seat is formed and a valve body is mounted, according to the invention has a snorkel-like air channel for forming a fluid opening.
  • the air channel allows the positioning of the fluid opening in a region away from the valve housing, so that, for example, even air can flow through the valve in a vent line when the valve housing including the valve seat and the valve body are under water and only the fluid opening is located above the waterline.
  • the present invention is particularly suitable for reliable pressure equalization of a water tank of an electric steam iron both in a vertical rest position and in a horizontal working position and for safe filling of the water tank.
  • FIG. 1 shows a longitudinal section through a front region of a known steam iron in a filling position
  • FIG. 2 shows a longitudinal section of the known steam iron of FIG. 1 in a vertical rest position
  • FIG. 3 shows a longitudinal section through a front region of a steam iron according to the invention in a filling position

  • the steam iron 33 has at least one casing 2, a water tank 4 accommodated in the casing 2, a tank vent 8 disposed in the water tank 4, and a steam chamber 6.
  • the steam iron 33 has a heated sole, not shown, and corresponding control devices such as a temperature selector switch for, for example, setting a desired water temperature and steam amount.
  • the tank vent 8 has a valve 34 arranged in a front region of the steam iron 33 or water tank 4 and a vent line 12 connected to the valve 34, which opens into the outside environment in a rear housing section of the steam iron 33.
  • the valve 34 is oriented in the longitudinal direction of the steam iron 33 and has a cup-shaped valve housing 14 with a cross-section widened tubular housing portion 22, a cross-section tapered tubular housing portion 26 and a cone-like transition section 28 interconnecting the two housing sections 22, 26
  • the cross-section tapered housing section 26 has a transversely extending connecting piece 18 for connecting the vent line 12.
  • the quer4.000ser shimmererte housing portion 22 serves to receive a spherical valve body 30 and is on its front side facing away from the valve seat 20 free end portion closed by a plate-like closure member 36. For simplified positioning of the closure element 36, this has an axial flange 38, which projects into the end section and is located peripherally in contact therewith.
  • the valve body 30 has a spherical shape and consists at least partially of a metallic material or a corresponding alloy. It is freely movable in the cross-sectional widened housing portion 28 and is brought into contact with the valve seat 20 only by virtue of its weight force or removed therefrom. In the filling position shown in FIG. 3, the valve body 30 sealingly rests on the valve seat 20, so that the valve 34 is closed and the water flowing into the water tank 4 can not escape via the tank vent 8.

  • the air duct 42 and the valve housing 14 have approximately the same axial extension, wherein in the embodiment shown here in the rest position shown in Figure 4, the fluid opening above the valve seat 20 and the connecting piece 18 is arranged.
