Benefits of technology

The invention is a hand-held appliance with a unique valve design for each tube inlet. Each valve assembly is removable, making it easier to manufacture and assemble. The length of the tube and the size of the reservoir do not affect the valve assembly. The valve assembly allows for separate control of air and water flow through the valve, and the valve member drops under its own weight to prevent air flow. The valve is designed to be used with different size and shapes of reservoirs. Overall, the invention provides a simple valve construction with flexible and easy-to-assemble components.

Problems solved by technology

This results in air being drawn into the heating chamber 4 rather than water, preventing efficient steam generation.
Furthermore, the appliance need not be capable of generating steam, in which case the fluid, such as water contained in the reservoir can be delivered directly onto a surface to be cleaned.

Embodiment Construction

[0028]Embodiments of the invention will now be described, by way of example only, with reference to FIGS. 2 to 5 of the accompanying drawings.

[0029]There is shown in FIGS. 2a and 2b a partial view of a first embodiment of a hand-held appliance 10 that is capable of generating steam and which comprises a housing 2 and a reservoir 3, similar to the conventional hand-held steamer 1 described with reference to FIG. 1 above. However, the portion 7 of the tube 6 (see FIG. 1) that extends into the reservoir 3 now has two tube inlets 11, 12 which are positioned at opposite ends of the reservoir 3. A valve assembly 13, 14 is positioned at each inlet 11, 12. When the hand-held steamer 10 is positioned in the orientation shown in FIG. 2a, i.e. in the same orientation as the hand-held steamer 1 shown in FIG. 1, inlet 11 is lowest and will be submerged in any water contained in the reservoir 3. The valve assembly 13 associated with the inlet 11 will then be in an open position to allow water to ...

Abstract

The present application relates to a hand-held appliance comprising a housing including a reservoir to contain water and a tube to convey water from the reservoir for delivery to a surface. The tube extends into the reservoir and comprises multiple tube inlets spaced from each other within the reservoir so that, when the reservoir contains water, a tube inlet is submerged irrespective of the orientation of the housing. In one embodiment, the tube inlet comprises a separate valve assembly associated with each tube inlet so that a valve assembly associated with a submerged tube inlet opens to allow flow of water through that tube inlet and a valve assembly associated with a non-submerged tube inlet closes to prevent the flow of air through said non-submerged tube inlet. In an alternate embodiment, the appliance may be provided with a single valve member that allows water to flow through the valve assembly via a first opening, whilst also preventing the flow of air through the valve assembly through a second opening.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a hand-held appliance in which a water reservoir is mounted within a housing that is held in the hand and which has an outlet or nozzle to discharge fluid or steam onto a surface, such as a garment, a fabric article such as a curtain or fabric covered items of furniture. The hand-held appliance of the invention may also be used to clean solid surfaces such as floors or counter tops by the application of steam and / or fluid to the surface.BACKGROUND OF THE INVENTION[0002]A conventional hand-held garment steamer 1 is illustrated in FIG. 1, and comprises a housing 2 containing a water tank or reservoir 3 and a heating chamber 4. Water is delivered from the reservoir 3 to the heating chamber 4 via a delivery system comprising a pump 5 and a tube 6 that has a portion 7 which extends into the reservoir 3 and which has an inlet 8 at its free end for the flow of water into the portion 7 of the tube 6 and along the tube 6 into the h...
