Definitions

  • a garment steaming device with increased water head is provided.
  • the present invention relates to a garment steaming device and more specifically to a garment steaming device that comprises a steam iron.
  • Garment steaming devices such as steam irons, generate steam for removing creases and wrinkles from fabric.
  • the most common method of producing steam is to dose water from a reservoir through a controlled orifice into a steam generator where it is heated to generate steam.
  • the reservoir is normally above the steam generator in an operational position of the garment steamer so that gravity influences the flow of water from the reservoir into the steam generator.
  • Water dosed into the steam generator is evaporated.
  • the volumetric expansion that takes place can cause instances of relatively high pressure to occur.
  • This high pressure in the steam generator can exceed the pressure at the orifice caused by the hydraulic head of water in the reservoir above the steam generator, especially when the steam vents through which steam is ejected onto a fabric being treated are blocked or covered by the fabric.
  • the dosing of water into the steam generator through the orifice is restricted until the pressure in the steam generator falls below the pressure at the orifice generated by the hydraulic head of water in the reservoir. As water is restricted from entering the steam generator, the rate at which steam is produced is reduced compromising performance of the device.
  • Patent US 4484399 A discloses a steam iron having a heated soleplate and a water reservoir with at least one manually operable passageway for the measured delivery of water into a vaporisation cavity adjoining the soleplate.
  • Patent US 2016/122937 Al discloses the use of two water chambers in a cordless steam iron to prevent excessive unwanted condensation.
  • Patent US 2 700 236 discloses a water reservoir having a horizontal extension that extends over the cover plate. Ejection of steam is controlled by the operator by means of pump lever that is engaged with a pump cylinder, when actuated water is passed from the water reservoir via the pump cylinder into the steam generating chamber.
  • Patent JP H03 77586 A discloses a water tank formed of a first storage water chamber in a front section of the iron and a second storage water chamber in a rear section of the tank to ensure that water is fed smoothly into the evaporation chamber.
  • a garment steaming device comprising:
  • vent pipe connected to a top part of the second water chamber by its first end and open to the atmosphere at its second end , the second end of the vent pipe extending at least as far as the maximum water level height of the first water chamber when the garment steaming device is in a non- operational orientation;
  • the second water chamber is arranged higher than the first water chamber in the operational orientation so that a water level height of the second water chamber is higher than a water level height of the first water chamber in said operational orientation, so that the water head in the first fluid path generated by the fluid coupling the second water chamber and the first water chamber is increased to obtain an increased steam rate when the garment steaming device is in the operation orientation.
  • the second water chamber is arranged wholly above the first water chamber in the operational orientation.
  • the second water chamber and the first water chamber are arranged such that when the garment steaming device is moved into its non-operational orientation from the operational orientation, water is displaced from the first water chamber into the second water chamber through the second fluid path until the water level heights in the first water chamber and the vent pipe are the same. Therefore, the ability to replenish the second water chamber, by moving the garment steaming device into its non- operational orientation, allows an increased water head to be re-established once the garment steaming device is returned to its operational orientation for further use.
  • the first fluid path may be arranged higher than the maximum water level height of the first water chamber when the garment steaming device is in the non-operational orientation to allow the air in the steam generator to pass into the first water chamber through the first fluid path as the water is displaced from the first water chamber into the second water chamber. Therefore, the first water chamber, the second water chamber, and the vent pipe can act as communicating vessels so that the water level in the first water chamber and the second water chamber or the vent pipe is the same. This allows more water to flow through the second fluid path and be retained in the second water chamber to provide an increased water head when the garment steaming device is returned to its operational orientation allowing an increased steam generation rate to be maintained.
  • the first water chamber, the second fluid path, the second water chamber, and the vent pipe are conjointly formed into a substantially "U"-shaped
  • the capacity of the second water chamber is in the range of 5 ml to 50 ml.
  • a smaller second water chamber capacity provides a shorter duration during which an increased water head is provided before the device needs to be moved into its non- operational position to refill the second water chamber.
  • a larger second water chamber provides a longer duration during which an increased water head is provided.
  • the capacity of the second water chamber can be tailored to the steam generator to ensure that the increased water flow rate through the first fluid path caused by the increased water head provided by the second water chamber does not overfill the steam generator and cause it to cool to a temperature which is too low to generate steam.
  • the cross-sectional diameter of the second fluid path is in the range of 2 mm to 15 mm. Therefore, the effective flow path resistance during replenishment of the second water chamber can be controlled. The smaller the cross-sectional diameter of the second fluid path, the larger the flow resistance and so the longer it takes to replenish the second water chamber.
  • the second fluid path may be formed into a right angle- shaped construction between the first water chamber and the second water chamber.
  • the second fluid path is formed integrally with or separately from the first water chamber and/or the second water chamber.
  • the first water chamber comprises a water inlet and a sealing member located on the sidewall thereof, the water inlet being configured to allow the first water chamber and the second water chamber to be filled with water in the non- operational orientation, the sealing member being configured to seal the water inlet once the first water chamber and the second water chamber have been filled and prior to the movement of the garment steaming device into the operational orientation. Therefore, the garment steaming device can be easily filled with water when in the non-operational orientation so that it is filled to the maximum water level height. Sealing of the water inlet traps air in the first water chamber when the garment steaming device is moved into the operational orientation so that water held in the second water chamber cannot fill the first water chamber and the increased water head is maintained.
  • the garment steaming device may be a steam iron.
  • the non- operational orientation indicates an orientation in which the steam iron may be rested on its heel portion on a countertop. Therefore, a user can leave the steam iron to stand unsupported whilst the second water chamber is replenished by the first water chamber.
  • the iron may be held in the hand of a user in its non- operational orientation whilst the second water chamber is replenished by the first water chamber.
  • the second water chamber is arranged in the heel portion behind a back cover. Therefore, when the steam iron is placed on its heel portion, the water flows from the first water chamber to the second water chamber under the influence of gravity.
  • the vent pipe may be arranged inside a handle of the steam iron.
  • a soleplate situated against the steam generator in which water is converted into steam, the soleplate having multiple steam venting holes therein and facing the garment to be ironed once the garment steaming device is moved into the operational orientation from the non- operational orientation.
  • the steam generated at an increased or consistent rate, can be directed onto the garment to be treated.
  • a consistent steam rate will increase the steam iron's performance and help to remove creases.

  • a first fluid path 6 fluidly communicates the first water chamber 2 and the steam generator 5.
  • a second fluid path 7 fluidly communicates, via a second fluid path inlet 8, a bottom end of the first water chamber 2 with a lower part of the second water chamber 3, via a second fluid path outlet 9.

  • the pipe can be straight, but inclined between a lower point defined by the first end 11 and a higher point defined by the second end 12.
  • the second water chamber 3 is arranged higher than the first water chamber 2 in the operational orientation A so that a water level height of the second water chamber 3 can be higher than a water level height of the first water chamber 2 in said operational orientation A. This results in that the water head in the first fluid path 6 generated by the fluid coupling of the second water chamber 3 and the first water chamber 2 to the steam generator 5 under gravity is increased.

It will be understood that the second water chamber 3 may extend towards the first end 15 of the heated plate 14 above the first water chamber 2. In some embodiments, the whole of the second water chamber 3 may be arranged at a greater vertical distance from the steam generator 5 than the first water chamber 2 when the garment steaming device 1 is in its operational orientation A.

  • the first fluid path 6 is formed in a bottom wall 24 of the first water chamber 2 so that it is below the water level in the first water chamber 2 when the garment steaming device 1 is in its operational orientation A until substantially all the water has been dosed into the steam generator 5.
  • the second fluid path inlet 8 and the orifice 21 are positioned so that when the garment steaming device 1 is in its operational orientation A, the second fluid path inlet 8 and the orifice 21 will be below the water level in the first water chamber 2 until the water in the first water chamber 2 is substantially depleted. Therefore, the orifice 21 that is connected to the second fluid path 7 is located in a wall of the first water chamber 2 proximate to the heated plate 14. That is, the orifice 21 is located in the bottom wall 24 or a side wall 25 proximate the bottom wall 24, as shown in Fig. 1, of the first water chamber 2.

That is, the vent pipe 10 extends from the top wall 18, as shown in Fig. 1, or from the side wall 27 proximate the top wall 18. In this way, the vent pipe 10 is normally above the water level in the second water chamber 3 when the garment steaming device 1 is in its operational orientation A. Referring to Fig.
  • the first and second water chambers 2, 3 are arranged such that, when the garment steaming device 1 is moved from its operational orientation A to its non- operational orientation B, water flows from the first water chamber 2 into the second water chamber 3 and vent pipe 10 through the second fluid path 7 until the water levels in the first water chambers 2 is are at the same level as the water in the second water chamber 3 or vent pipe 10. That is, in the non-operational orientation B, the second fluid path inlet 8 is configured to allow the flow of water from the first water chamber 2 into the second fluid path 7 and the second fluid path outlet 9 is configured to allow the flow of water from the second fluid path 7 into the second water chamber 3 and into the vent pipe 10.

  • the vent pipe 10 extends towards the first end 15 of the heating plate 14 by a distance at least as far as the maximum water level height of the garment steaming device 1 when in its non- operational orientation B.

That is, the vent pipe 10 extends to the same height or higher than the maximum water level of the first water chamber 2 when the garment steaming device 1 is in its non- operational orientation B.
  • the garment steaming device 1 may comprise a 'snap-disc' mechanism (not shown) which is configured to control the flow of water through the first fluid path 6.
  • the 'snap-disc' mechanism may be located at either end of or in the first fluid path 6.
  • the state of the 'snap-disc' mechanism is dependent on the temperature of the steam generator 5. That is, if the steam generator 5 is sufficiently heated to evaporate water and produce steam, the 'snap-disc' mechanism will be in a state which opens the first fluid flow path 6 and allows water to flow through the first fluid path 6 from the first water chamber 2 into the steam generator 5.
  • the 'snap-disc' mechanism will be in a state which closes the first fluid path 6 so that there is no flow of water to the steam generator 5. Therefore, before the garment steaming device 1 is heated up, the 'snap-disc' mechanism will close the first fluid path 6. Consequently, in the preferred embodiment, the position of the first fluid path 6 does not define the maximum water level in the first water chamber 2 in the non- operational orientation B and the vent pipe 10 may extend as far as the top end of the first water chamber 2 proximate the first end 15 of the heated plate 14. As a result, the first water chamber 2 may be completely filled with water in the non- operational orientation B before the garment steaming device 1 is turned on.
  • the garment steaming device 1 may further comprises another specific mechanism (not shown), such as a button, which is configured to override the 'snap- disc' mechanism so that it keeps the first fluid path 6 totally closed. Therefore, the garment steaming device 1 can be used for, for example, "dry ironing” (ironing without steam).
  • the first water chamber 2 further comprises a water inlet 29 configured to allow the first and second water chambers 2, 3 to be filled with water when the garment steaming device 1 is in its non-operational orientation B and a sealing member 30 configured to seal the water inlet 29 once the water chambers 2, 3 have been filled.
  • the sealing member 30 may be, for example, but not limited to, a hinged door comprising an ' ⁇ '- ring to seal the door against the walls of the first water chamber 2.
  • the water inlet 29 should be located closer to the end of the first water chamber 2 proximate the first end 15 of the heated plate 14 than the first fluid path 6.

  • the first water chamber 2 is fluidly connected to the atmosphere via the open water inlet 29 and the first fluid path 6, and the second water chamber 3 is fluidly connected to the atmosphere via the second end 12 of the vent pipe 10. Therefore, the first and second water chambers 2, 3 act as communicating vessels and so the water level in the first water chamber 2 and the vent pipe 10 are always at the same height.
  • the first and second water chambers 2, 3 are filled with water until the water level is just below the first fluid path 6 whilst the garment steaming device 1 is in its non-operational orientation B and the water inlet 29 is sealed closed by the sealing member 30. At this point the first water chamber 2 is open to the atmosphere via the first fluid path 6.
  • the garment steaming device 1 is moved back into its operational orientation A in which the steam generator 5 extends horizontally. Because the orifice 21 connected to the second fluid path inlet 8 is below the water level in the first water chamber 2, the air in the first water chamber 2 becomes trapped. The air in the first water chamber 2 is sealed under pressure by the hydraulic head achieved by the water in the second water chamber 3 being at a greater vertical height from the steam generator 5 than the water in the first water chamber 2. The larger the height of the water level in the second water chamber 3 from the first fluid path 6 the larger the hydraulic head. As shown in Fig. 2c, water may be in the vent pipe 10 when the garment steaming device 1 has just been filled and will contribute to the overall water head.
  • the greater hydraulic head achieved by the second water chamber 3 holding water above the water level in the first water chamber 2 causes a higher pressure at the first fluid path 6 than would occur without water in the second water chamber 3. Therefore, a higher dosing rate can be achieved which results in a larger steam rate.
  • water can be forced through the first fluid path 6 in instances of higher pressure created by the volumetric expansion of water in the steam generator 5. This helps to overcome the prevention of water dosage into the steam generator 5 that is encountered in previous steam generating devices.
  • the hydraulic head can prevent the back flow of steam from the steam generator 5 into the first water chamber 2. Referring now to Fig. 2d, as steaming continues water from the first water chamber 2 is directed through the first fluid path 6 and into the steam generator 5.
  • the air in the first water chamber 2 remains sealed and under pressure caused by the hydraulic head achieved in the second water chamber 3. Therefore, the water that exits the first water chamber 2 into the steam generator 5 is replaced by water from the second water chamber 3.
  • the water level in the second water chamber 3 becomes lower which results in a lower hydraulic head and therefore, a slowing steam rate as the difference in pressure between the first fluid path 6 and the steam generator 5 decreases.
  • the capacity of the second water chamber 3 must be chosen carefully to fit the garment steaming device 1.
  • the second water chamber 3 may have a capacity of between 5 and 50 ml. Preferably, the second water chamber 3 has a capacity of 20 ml. The larger the second water chamber 3, the longer the duration of a higher steam rate whilst the garment steaming device 1 remains in its operational orientation.
  • the capacity of water that the second water chamber 3 can hold and the volume of the second water chamber 3 may differ.
  • Another parameter that can be controlled is the effective flow path diameter of the water.
  • the minimum cross-sectional diameter of the second fluid path 7 is between 2 to 15 mm.
  • the minimum cross-sectional area is 5 mm.
  • the garment steaming device 1 can be rotated back into its non-operational orientation B from its operational orientation A.
  • water from the first water chamber 2 flows through the second fluid path inlet 8 into the second fluid path 7 and through the second fluid path outlet 9 into the second water chamber 3.

Pressure in the first water chamber 2 and the vent pipe 10 are both atmospheric once again.
  • Fig. 2g it can be seen that water from the second water chamber 3 and second fluid path 7 continue to replenish the water in the first water chamber 2 even once the water level in the second water chamber 3 or second fluid path 7 is below the water level in the first water chamber 2. This is because of the atmospheric pressure acting on the water in the second water chamber 3 or second fluid path 7. The atmospheric pressure acts on the water to try and keep the air trapped in the first water chamber 2 at atmospheric pressure.

Le dispositif de vaporisation (1) de vêtement comprend également un premier trajet de fluide (6) reliant la première chambre à eau (2) au générateur de vapeur (5), un second trajet de fluide (7) reliant une extrémité inférieure de la première chambre à eau (2) à une partie inférieure de la seconde chambre à eau (3), un tuyau d'évent (10) relié à une partie supérieure de la seconde chambre à eau (3) au moyen de sa première extrémité (11) et étant ouvert vers l'atmosphère à sa seconde extrémité (12). La seconde extrémité (12) du tuyau d'évent (10) s'étend au moins jusqu'à la hauteur maximale du niveau d'eau de la première chambre à eau (2) lorsque le dispositif de vaporisation (1) de vêtement est dans une orientation de non-fonctionnement (B). La seconde chambre à eau (3) est disposée plus haut que la première chambre à eau (2) dans l'orientation de fonctionnement (A) de sorte qu'une hauteur du niveau de l'eau de la seconde chambre à eau (3) est supérieure à une hauteur du niveau de l'eau de la première chambre à eau (2) dans ladite orientation de fonctionnement (A), de sorte que la charge d'eau, dans le premier trajet de fluide (6), générée par le fluide reliant la seconde chambre à eau (3) à la première chambre à eau (2) est augmentée afin d'obtenir un taux de vapeur plus élevé lorsque le dispositif de vaporisation de vêtement est dans l'orientation de fonctionnement (A).
