Definitions

  • 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.
  • a conventional hand-held garment steamer 1 is illustrated in Figure 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 heating chamber 4. Water delivered to the heating chamber 4 is converted into steam for delivery to the surface being steamed through an outlet 9.
  • the housing 2 is orientated in its intended position of use so that steam is ejected through the outlet 9 in a substantially horizontal direction, as indicated by arrow A.
  • the portion 7 of the tube 6 extends into the reservoir 3 such that the inlet 8 is positioned at the lowest point in the reservoir 3 when the hand-held steamer is held in its intended orientation during use so that substantially all the water in the reservoir 3 will be drawn into the heating chamber 4, i.e. in the vertical orientation shown in Figure 1 , in which steam exits the outlet 9 substantially horizontally.
  • it is also desirable to be able to use the hand-held steamer 1 in other orientations such as when steaming garments or fabric articles placed on an ironing board or when steaming fabric covered items of furniture. In these circumstances, the hand-held steamer 1 will be held in a non-vertical orientation and may even be held horizontally so that steam is exits the housing through the outlet 9 in a substantially vertical direction.
  • the present invention seeks to provide a hand-held appliance that overcomes or substantially alleviates the problems with a conventional hand-held appliance, such as those identified above, and which maintains adequate delivery of fluid or steam to a surface irrespective of the orientation of the appliance.
  • the appliance of the invention may be used for a variety of different purposes and may, for example, be used for cleaning solid surfaces such as floors or windows as well as steam ironing of fabric articles or garments.
  • 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.
  • the appliance is provided with a heating chamber so that water contained in the reservoir is delivered to the heating chamber to be turned into steam prior to delivery to a surface.
  • the appliance may be provided with a switch that provides a user with the option to deliver liquid or steam to a surface. For example, it may be possible to use the appliance with the heating chamber switched off.
  • a hand-held appliance is characterised in that the tube comprises multiple inlets spaced from each other within the reservoir so that, when the reservoir contains water, an inlet is submerged irrespective of the orientation of the housing, the tube portion also comprising 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 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.
  • the tube portion contains multiple inlets, at least one tube inlet will always be in a submerged position irrespective of the orientation of the appliance.
  • the hand-held appliance will therefore continue to emit fluid or steam consistently in whatever position or orientation it is held in.
  • the tube inlets which are located above the water line are closed by the valve which is associated with the non-submerged tube inlet, no air will be drawn into the heating chamber through that, or those, tube inlet(s).
  • each valve assembly comprises a housing and a single valve member movable within the housing between a first position in which the inlet is open to allow water to flow past the valve into the inlet and a second position in which the inlet is closed to prevent the passage of air into the inlet.
  • the valve member may drop under its own weight into its first position and in a direction away from its associated inlet.
  • each valve assembly is removably mounted to an end of the tube over the inlet.
  • the aforementioned features provide a hand-held appliance in which an independent, but identical valve design is used for each tube inlet.
  • a separate valve assembly is removably attached to each end of the tube over an inlet, the assembly becomes more flexible and easier to manufacture and assemble. It also means that more than two inlets can be used without having to re-design the valve assembly, as a separate but identical valve assembly is simply provided for each inlet.
  • the length of the tube portion within the reservoir is also irrelevant, as the valve assembly can be attached to the end of a tube of any length. It is therefore applicable to hand-held appliances having reservoirs of various different sizes and shapes. As each valve assembly may be removable, they can be replaced easily due to wear or malfunction without replacing the other valve assembly or assemblies.
  • the tube portion comprises a primary tube portion extending into the reservoir and a secondary tube portion attached to a free end of the primary tube portion at a junction, a separate valve assembly being mounted to each end of the secondary tube portion remote from said junction.
  • the primary tube portion may extend into the reservoir so that its free end is positioned roughly at a central point within the reservoir.
  • the secondary tube portion can then extend to opposite ends of the reservoir so that at least one inlet will always be submerged in any water in the reservoir irrespective of the orientation of the appliance.
  • the secondary tube portion may comprise two inlets and may be integrally formed with a connector for attachment to said free end of the primary tube portion to effect fluid communication between the secondary tube portion and the primary tube portion.
  • the connector may comprise a connection piece integrally formed with the secondary tube portion for fluidly connecting the secondary tube portion to the free end of the primary tube portion.
  • the secondary tube portion may be a linear or straight section of tubing, and the connection piece can extend at right angles from the secondary tube portion at a point midway between each end of the secondary tube portion so that each tube inlet is positioned at approximately the same distance away from the free end of the primary tube portion.
  • the connection piece may simply be a short, hollow length of tube that is a push fit into the free end of the primary tube portion so as to effect fluid communication between the primary tube portion and the secondary tube portion.
  • the secondary tube portion maybe formed of a plurality of independent sections.
  • each independent section may be attached to the free end of the primary tube portion via a connecting element to effect fluid communication between each independent section and the primary tube portion.
  • the secondary tube portion may comprise two independent sections and so the connecting element may, for example, be T-shaped so that each end of the 'T' forms a connector that is a push fit within the end of each tube to be connected. If the connecting element is substantially T-shaped, each independent section may extend away from each other in opposite directions and the primary tube portion may extend substantially at right-angles to each independent section.
  • a hand-held appliance is characterised in that the tube comprises two inlets spaced from each other within the reservoir so that, when the reservoir contains water, at least one of said inlets is submerged irrespective of the orientation of the housing, the tube portion comprising a valve assembly having an outlet, first and second openings and a single valve member within said valve assembly that allows water to flow through the valve assembly via the first opening, whilst also preventing the flow of air through the valve assembly through the second opening, the valve member being configured such that it drops under its own weight into an alternate position in response to a change in the orientation of the appliance to allow water to flow through said second opening via one of said inlets whilst preventing the flow of air through said first opening via the other of said inlets.
  • the appliance according to this aspect of the invention has a simple valve construction, as only one valve member is required to control flow through each of the first and second openings.
  • the tube comprises a primary tube portion that extends into the reservoir so that a free end of said primary tube portion is in fluid communication with the outlet of the valve assembly, and a secondary tube portion extends from each of the first and second openings of the valve assembly, said tube portions being configured such that the valve member drops in a direction toward the opening from which a tube portion having the uppermost inlet extends, depending upon the orientation of the hand-held appliance, to prevent the flow of air through said opening from said secondary tube portion.
  • a hand-held appliance is characterised in that the secondary tube portion comprising an inlet at each end spaced from each other within the reservoir, and a valve element received within the secondary tube portion, said valve element being slideable under its own weight in response to a change in orientation of the valve element so that, depending upon the orientation of the steamer, an uppermost inlet is closed to prevent the flow of air into the secondary tube portion and the lowermost inlet is open to allow the flow of water into the secondary tube portion.
  • the hand-held appliance includes a heating chamber and the tube is configured to convey water from the reservoir to the heating chamber to generate steam prior to delivery to a surface.
  • FIG. 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 Figure 1 above.
  • the portion 7 of the tube 6 (see Figure 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.
  • valve assembly 13 associated with the inlet 11 will then be in an open position to allow water to flow from the reservoir 3 into the portion 7 of the tube 6, whereas the valve assembly 14 associated with the other inlet 12, which is positioned above inlet 11, will be closed to prevent air from entering the portion 7 of the tube 6.
  • Each valve assembly 13, 14 is attached to the portion 7 of the tube 6 over each inlet 11,12.
  • Each valve assembly 13,14 is preferably releasably attached to the portion 7 to enable independent removal and replacement of each valve assembly 13,14, although it is envisaged that one or both valve assemblies 13,14 can be permanently attached to the portion 7 or otherwise formed integrally with it.
  • Each valve assembly 13,14 contains a valve member in the form of a weighted body or ball 15 that drops due to gravity and does not float. As shown in Figure 2a , both bodies 15 have dropped under gravity so that the body 15 of the valve assembly 14 associated with the upper inlet 12 is in contact with a valve seat 16 at the end of the portion 7, thereby closing the upper inlet 12 and preventing the passage of air into the portion 7.
  • the body 15 of the valve assembly 13 associated with the lower inlet 11 is in a position in which it is distanced from its corresponding valve seat 16, thereby allowing water to flow into the portion 7 past the body 15.
  • the body 15 is held in a cage 17 to constrain its movement and prevent it from falling out.
  • the cage 17 has openings or passages therein to allow water to flow around the body 15 and into the inlet 11 when the body 15 is spaced from its valve seat 16.
  • FIG 2b illustrates the same hand-held steamer 10 as shown in Figure 2a , but in an orientation in which steam is directed out of the outlet 9 (see Figure 1 ) in the housing 2 onto the garment being steamed in a vertically downward direction.
  • the housing 2 may be held in this orientation when, for example, a fabric article that has been placed on an ironing board or on a table or such like is being steamed or, when steaming an item of furniture.
  • inlet 12 is now positioned below inlet 11 and will be submerged in any water contained in the reservoir 3 whereas, depending on the amount of water in the reservoir 3, inlet 11 will be above the water line. Therefore, valve assembly 13 associated with inlet 11 is closed to prevent the ingress of air whilst valve assembly 14 associated with inlet 12 is open to maintain a flow of water to the heating chamber 4 (see Figure 1 ).
  • the portion 7 of the tube 6 within the reservoir 3 may comprise a primary tube portion 18 that extends from a flow control valve 19 in the wall of the reservoir 3, which is connected to a secondary tube portion 20.
  • the inlet 11 is at one end of the secondary tube portion 20 and the other inlet 12 is at the opposite end of the secondary tube portion 20.
  • the secondary tube portion 20 has an integral connector 21 positioned midway between the inlets 11, 12 to fluidly connect it to a free end of the primary tube portion 18.
  • the secondary tube portion 20 may extend diagonally across the inside of the reservoir 3 so that, when the housing 2 is in the position shown in Figure 2b , inlet 12 will be below inlet 11.
  • the primary tube portion 18 and/or the secondary tube portion 20 may be formed from rigid or flexible parts or a combination of both.
  • FIG. 3 A modified version of the steamer 10 shown in Figure 2a and 2b is shown in Figure 3 .
  • the secondary tube portion 20 is formed in two parts 20a, 20b fluidly connected together by a separate T-shaped connector 22, which also fluidly connects the two parts 20a, 20b to the free end of the primary tube portion 18.
  • Each secondary tube portion 20a, 20b may be formed from flexible or rigid tubing.
  • Figures 2a, 2b and Figure 3 each have a secondary tube portion 20, 20a, 20b that has two inlets
  • the secondary tube portion 20a, 20b could also be provided with more than two inlets, each inlet being positioned in a different location within the reservoir 3. Further inlets may be required depending upon the shape of the reservoir 3 and so as to ensure that at least one inlet will be submerged in any water remaining in the reservoir 3 irrespective of the orientation of the steamer.
  • the primary tube portion 18 is connected directly a single fluid flow control valve 23 which is located roughly centrally within the reservoir 3.
  • Secondary tube portions 24a, 24b are fluidly attached to, and extend in opposite directions from, the fluid flow control valve 23.
  • An inlet 25, 26 is provided at the end of each secondary tube section 24a, 24b.
  • the fluid flow control valve 23 comprises a valve housing 27 containing a weighted body 30 which toggles between a first position at one end of the valve housing 27, as shown in Figure 4a , in which it sits against a first valve seat 28 to close the secondary tube portion 24a and stop ingress of air into inlet 25; and a second position, as shown in Figure 4b , in which it sits against a second valve seat 29 at the opposite end of the valve housing 27 to close the secondary tube portion 24b and stop ingress of air into inlet 26.
  • the weighted body 30 moves between its first and second positions under gravity and in response to a change in the orientation of the housing 2.
  • the body 30 sits against valve seat 28 to close the secondary tube portion 24a and, when the housing 2 is in an orientation in which steam is emitted from the outlet 9 in a substantially vertical direction as shown in Figure 4b , the body 30 sits against valve seat 29 to close the secondary tube portion 24b.
  • the secondary tube portion 24a is positioned so that the inlet 25 is lower than the inlet 26 at the end of the other secondary tube portion 24b when the housing 2 is in the orientation shown in Figure 4b so that the inlet 25 will always be submerged in any water contained in the reservoir 3 when the housing 2 is in this position.
  • FIG. 5a and 5b A further embodiment is shown in Figures 5a and 5b .
  • the portion 7 of the tube 6 has a secondary tube portion 31 connected to the free end of the primary tube portion 18, as in the embodiment of Figure 2a and 2b .
  • the valve assembly is formed by a rod 32 slideably received in the secondary tube portion 31 so that it protrudes from the inlets 33, 34 at each end of the secondary tube portion 31.
  • An enlarged head 35a, 35b is provided at each end of the rod 32 and carries a sealing disc 36a, 36b that faces its corresponding inlet end 33, 34 of the secondary tube portion 31.
