Definitions

  • the present invention relates to a washing apparatus, and in particular, but not exclusively, to a washing apparatus for washing dishes (ie cutlery, crockery, pot and pans etc); clothes; or machine parts.
  • the present invention was inspired by the inherent inefficiency of commercially available domestic automati ⁇ dishwashers.
  • a dishwasher In general, a dishwasher is able to wash dishes only because it maintains the dishes in contact with very hot water and corrosive chemicals for an extended period of time. Further, notwithstanding claims by their manufacturers, many dishwashers are unable to effectively clean dishes which have baked on or dried foodstuffs. Many manufacturers also recommend against placing wooden handled items, glued items, fine china/crystal; or heat sensitive items in their dishwashers.
  • the washing apparatus can be used to wash many different types of articles.
  • a washing apparatus including: a washing vessel divided into a washing chamber in which articles to be washed are deposited and a catchment chamber for catching dirt or other foreign matter washed from the articles; - 2 - the washing chamber and catchment chamber in fluid communication to allow a recirculating flow of cleaning liquid from the washing chamber through the catchment chamber and back to the washing chamber; and, a first air inlet for directing air into the washing chamber from a location below any article deposited in the washing chamber for cleaning; whereby, in use, the washing vessel is filled with a cleaning liquid to a predetermined level and air is directed through the first air inlet into the washing chamber, the air forming air bubbles which flow across the articles and turbulate the cleaning fluid within the washing chamber thereby washing dirt or other foreign matter from the articles, the air also acting to create a recirculating flow of cleaning liquid from the washing chamber to the catchment chamber and back to the washing chamber, the recirculating flow carrying dirt or other foreign particles washed from the articles into the catchment
  • the apparatus includes a wall over which cleaning liquid must flow to enter the catchment chamber from the washing chamber, forming an upper flow path for the cleaning liquid.
  • the wall divides the washing vessel into said washing chamber and catchment chamber, the wall configured to provide a lower flow path through which cleaning fluid can flow from the catchment chamber to the washing chamber.
  • the wall is shaped to form a gutter about an inside wall of the washing vessel and the catchment chamber includes one or more pipes leading from the gutter back to the washing chamber thereby providing a lower flow path through which cleaning fluid can flow from the catchment chamber to the washing chamber.
  • the apparatus includes a valve for selectively opening and closing the lower flow path, whereby when the one way valve is closed, the catchment chamber can be drained of cleaning liquid separately from the washing chamber.
  • the valve is a one way valve to prevent a back flow of cleaning liquid from the washing chamber to the catchment chamber.
  • the one way valve comprises a gate or flap which is hung or hinged to the wall so as to close when liquid pressure in the washing chamber exceeds liquid pressure in the catchment chamber.
  • the first air inlet includes a plate provided with a plurality of through holes, the plate overlying and spaced above a bottom wall of the washing chamber to form, with the bottom wall, a manifold chamber into which air is delivered for bubbling through the washing chamber.
  • the plate is inclined to allow drainage of cleaning liquid when the washing vessel or washing chamber is drained.
  • the catchment chamber returns cleaning liquid to the washing chamber at a location above the plate.
  • the bottom of the catchment chamber is sunk to a position below the lower flow path to provide a relatively static pool of cleaning liquid in which the dirt and foreign matter can settle.
  • the lower flow path returns cleaning fluid to a location below the plate.
  • the manifold chamber is adapted to receive a cleaning liquid supply line to allow the filing of the vessel with cleaning liquid via the manifold chamber and the holes in the plate.
  • each of the washing chamber and catchment chamber is provided with a separate drain to allow independent draining of the washing chamber and catchment chamber.
  • air and cleaning liquid can be simultaneously delivered to the manifold chamber to provide a mist or spray of cleaning liquid for rinsing articles deposited in the washing chamber.
  • the washing apparatus further includes a second air inlet for directing air onto articles held within the washing chamber when the washing chamber is drained of cleaning liquid to facilitate drying of the articles.
  • the catchment chamber is provided with a removable filter to assist in separating dirt and foreign material from the recirculating liquid.
  • the wall is slidably retainable at different locations within the washing vessel to allow variation in the position of the wall or removal of the wall.

  • the washing apparatus 10 includes a washing vessel 12 which is divided by a wall 14 into a washing chamber 16 in which articles 18 to be washed (in this embodiment the articles being dishes) are deposited, and a catchment chamber 20 for catching dirt and other foreign matter washed from the dishes 18.
  • the wall 14 is configured to allow a recirculating flow of cleaning liquid, such as water, between the washing chamber 16 and the catchment chamber 20 as indicated by arrows 22.
  • a first air inlet 24 is provided for directing air into the washing chamber 16 from a location below the dishes 18 deposited in the washing chamber 16.
  • the vessel 12 is filled with water to a predetermined level 26 and air is directed through the air inlet 24 into the washing chamber 16.
  • the air as it enters the chamber 16 forms bubbles which will flow across the dishes 18 and turbulate the water within the - 6 - chamber 16. This removes dirt or other foreign matter from the dishes 18.
  • the air which is bubbled through the chamber 16 also acts to create the recirculating flow 22 of water from the washing chamber 16 through the catchment chamber 20 and back to the washing chamber 16.
  • the recirculating flow 22 carries with it dirt or other foreign matter washed from the dishes 18. This is largely held in the catchment chamber 20 and thus separated from the recirculating flow 22.
  • the wall 14 is in the form of a rectangular plate 28 having an upper edge 30 and lower edge 32.
  • a row of holes 34 is formed along and slightly above the lower edge 32.
  • the plate 28 is of a height smaller than the depth of the vessel 12. Accordingly, as most clearly seen in Figure 1, a gap is formed between the upper edge 30 of plate 28 and a lid 36 of the vessel 12.
  • the predetermined level 26 of water within the vessel 12 is lower than the height of the plate 28.
  • the gap between the edge 30 and lid 36 provides an upper flow path through which water can flow from the washing chamber 16 to the catchment chamber 20.
  • the holes 34 in plate 28 form a lower flow path through which water in the catchment chamber 20 can flow back into the washing chamber 16.
  • the water is also drawn from the catchment chamber 20 by the lifting action of the air in the washing chamber 16. After the air has bubbled from the water held within the vessel 12, it escapes via a vent 40 to the atmosphere.
  • the vent 40 is provided on a side wall of the chamber 12 - 7 - at a level above the air lifted level 38 of water.
  • the recirculating flow 22 has the effect of carrying dirt or other foreign material washed from the plates 18 into the catchment area 20. Further, it has been discovered that the dirt or other foreign material largely remains entrapped within the catchment area 20 notwithstanding the recirculatory nature of the flow of water. This in effect separates the dirt or foreign material from the recirculating water. This effect is achieved even without the provision of any filter within the chamber 20. Nevertheless, this feature can be somewhat enhanced by the provision of a removal filter 42 disposed within the catchment chamber 20. It is thought that the lack of turbulence in the water within chamber 20 in comparison with the turbulence in chamber 16 largely provides the separation effect described above.
  • the air inlet 24 includes a plate 44 which is provided with a plurality of through holes 46.
  • the plate 44 is located within the washing chamber .16 and overlies and is spaced above a bottom wall 48 of the washing chamber 16.
  • the plate 44 together with the bottom wall 48 form a manifold chamber 50 into which can be provided both air and water.
  • an air supply conduit 52 is plumbed into the manifold chamber 50 via spaced apart risers 54 and 56 feeding from the conduit 52.
  • the conduit 54 is provided with a further riser 58 through which air can be diverted from the conduit 52 directly into the washing chamber 16.
  • a valve 60 is provided in conduit 52 upstream of the riser 58.
  • a further valve 62 is provided in riser 58 downstream of the valve 60.
  • a drain 64 is formed in the conduit 52 opposite the riser 56.
  • the drain 64 allows drainage for water which may otherwise enter the conduit 52.
  • a hose 66 provided with a click on connector 68 is used to couple the conduit 52 to a air supply such as a fan or blower (not shown).
  • a water conduit 70 is also plumbed into the manifold chamber 50 for supplying water to the vessel 12.
  • the water conduit 70 is adapted to receive a hose which in turn can be coupled to a - 8 - mains water supply. Two such conduits 70 may be provided to allow connection to separate hot and cold water supplies or a water supply and a detergent or additives supply.
  • a drain 72 is provided at the bottom of the catchment chamber 20.
  • a separate drain 74 is also provided at the bottom of the manifold chamber 50. Conveniently, the drains 64, 72 and 74 can be operated by respective solenoids to allow automation of the opening and closing of the drains.
  • the valve 62 is closed and air then delivered via hose 66, conduit 52 and risers 54 and 56 into the manifold chamber 50.
  • the air then bubbles through the holes 46 in plate 44 so as to rise through the water in the chamber 16.
  • the air bubbles flow across the surface of the plates 18 and turbulate the water.
  • the air displaces water within the chamber 16 causing the mean water level to rise to the level 38 which is above the upper edge 30 of wall 14. Accordingly, water flows over the edge 30 from the washing chamber 16 to the catchment chamber 20 to commence the recirculating flow 22 of the water. It will be appreciated that no air is bubbled through the catchment chamber 20. Accordingly, the water within the chamber 20 has a steady, rather than turbulent, flow.
  • the recirculating flow 22 carries with it dirt or other foreign material thereby directing them into the catchment chamber 20. Because of the non turbulent and steady flow of water in the chamber 20, the last proportion of the dirt and foreign matter seems to settle within the chamber 20 rather than flow - 9 - back into the washing chamber 20. In this way, the chamber 20 in effect acts to separate the dirt and foreign material from the recirculating flow. The separation can be assisted by the inclusion of the filter basket 42.
  • the drains 72 and 74 can be opened (which may then funnel into a common drain pipe, (not shown) to empty the vessel 12. If it is desired to provide a rinse to the dishes 18, a low volume supply of water can be delivered through conduit 70 simultaneously with the delivery of air through conduit 52. The air and water mix in the manifold chamber 50 and pass as a fine mist through the holes 46 in plate 44. If desired, a rinsing aid may be added to the water during this stage as it flows through the conduit 70. During the rinsing phase, the drains 72 and 74 would normally be left open. Once rinsing has been completed the supply of water to conduit 70 is turned off.
  • the dishes 18 can then be dried by delivering air through conduit 52 into the manifold chamber 50 which then passes across the dishes 18.
  • the valve 62 can be opened to allow air to be blown in, at least initially, a horizontal direction into the chamber 12.
  • the holes 34 of the first embodiment are replaced with an elongate slot 34'.
  • a one way valve 76 is provided on the wall 14 to prevent a back flow of liquid from the washing chamber 16 to the chamber 20 through the slot 34'.
  • the one way valve 76 is in the form of a gate or flap 78 which is hung or hinged onto the wall 14. The purpose of the valve 76 is to isolate the chambers 16 and 20 so that they can be drained separately. In particular, it may be desired to drain the catchment chamber 20 after completing a washing cycle but to maintain the water in chamber 16 for reuse.
  • the valve 76 is configured to close and more particularly seal the slot 34' - 10 - when no air is bubbled into the chamber 16.
  • the gate 78 may be biased by a spring or by the provision of a weight 80 disposed near its lowest edge. This will allow for example, the washing of say relatively clean dishes first (eg cups and glasses) followed then by washing of more heavily soiled articles such as pots and pans and dishes while minimising water use. Due to the ability of the apparatus 10 to separate the dirt and other matter from the articles being washed, the water in chamber 16 after one wash load remains relatively clean.
  • the water supply conduit 20 can be provided with a secondary branch which feeds directly into the chamber 20.
  • valve 76 (or another valve having the same purpose) can be operated electrically, say by a solenoid so as to close on demand to allow the separate draining of the chamber 20 from the chamber 16. This avoids the need of further plumbing to ensure initial filling of the chamber 20.
  • two washing apparatuses 10A and 10B in accordance with embodiments of this invention may be stacked on top of each other.
  • Each apparatus 10A and 10B is in a form substantially the same as that shown in Figures 1 and 2.
  • the water in the apparatus 10A can be drained by dumping into the lower apparatus 10B and then utilising the drains of apparatus 10B.
  • apparatus 10B is first loaded with articles by lifting apparatus 10A therefrom. Thereafter, the apparatus 10A is fitted on the top of apparatus 10B thereby acting as a lid for apparatus 10B. Articles are then loaded into the washing chamber 16 of apparatus 10A.
  • Apparatus 10A is operated in the normal manner described in relation to the first embodiment to clean the dishes held - 11 - therein. Once the cleaning has finished, the water in the chamber 20 of apparatus 10A is dumped into the chamber 20 of apparatus 10B and then drained completely from the system. This requires the use of the valve 76 or similar mechanism to allow the separate dumping of the water in chambers 16 and 20 of apparatus 10 A.
  • the water held in chamber 16 of apparatus 10A is dumped into underlying apparatus 10B typically by use of the drain 72 of the chamber 20 of the upper apparatus 10A.
  • the water being dumped from the washing chamber 16 of apparatus 10A into apparatus 10B will be relatively clean.
  • the water level in apparatus 10B is then topped up so as to reach the predetermined level 26 following which apparatus 10B operate in the normal manner. While apparatus 10B is being operated in this manner apparatus 10A can be separately operated to rinse and dry the articles held therein.
  • the minimisation can be further enhanced by dumping the water used in rinsing the articles held in apparatus 10A into the apparatus 10B prior to commencing the washing cycle of apparatus 10B.
  • the water from the catchment chamber 20 returns into the washing chamber 16 at a location above the air inlet 24/plate 44.
  • a water return chamber 84 is provided beneath the manifold chamber 50 and the water flowing in its lower path through the catchment chamber 20 is directed via valve 76 into the water return chamber 84.
  • the plate 44 is provided with a plurality of apertures 86 through which the water in the water return chamber 84 can flow back into the washing chamber 16.
  • the water is returned to the washing chamber 16 from a location below the plate 44.
  • FIG. 8 and 9 A further embodiment shown in Figures 8 and 9 where the catchment chambers 20 are formed by pipes 83 that extend from an upper portion of the washing chamber 16 and then turn the washing liquid to a water return chamber 84 underlying the manifold chamber 50.
  • the wall 14 now forms a gutter about the inside surface of the washing chamber 16, the gutter leading to the upper end of the pipes constituting the catchment chambers 20.
  • the lower end of the pipes 83 extend below the valves 76 to produce a relatively static pool in which dirt and other matter can settle prior to discharge through drain 72.
  • water can flow over the upper edge 30 of the wall 14 into the gutter from anywhere around the washing chamber 14. This further enhances the speed of cleaning as dirty water can be drawn into the catchment chambers 20 from all about the periphery of the washing chamber 14.
  • annular catchment chamber 20 is formed by a circular wall 14 of a diameter less than that of the washing vessel 12.
  • This embodiment is particularly well suited to allow easy changing of the volume of the washing chamber 16 by forming the wall 14 in demountable sections.
  • the wall 14 can be made in two circular parts that mate together about a circumferential line containing points A-A. In this form, with the top section of the wall 14 removed, a small wash requiring less water can be performed.
  • the washing chamber 16 can be provided with a movable partition so as to decreased its total volume. This allows the operation of the apparatus 10 for cleaning relatively small loads with commensurate lower volumes of water.
  • the partition in this instance ideally would extend to the lid 36.
  • the embodiments of the apparatus 10 can be used for cleaning essentially - 13 - any item which is normally cleaned by use of water and/or detergents/solvents.
  • the apparatus can be used for washing clothes, or machine parts.
  • the apparatus 10 can be incorporated into a typical domestic stainless steel sink so that, when used for cleaning dishes, dishes from say a dinner table can simply be loaded into the sink and then operated in the manner indicated above. In this form, a slide out lid or a separate lid will need to be applied across the top of the sink.

Abstract

Cette machine à laver (10) comprend une cuve de lavage (12) divisée par une paroi (14) en une chambre de lavage (16) dans laquelle sont placés les articles (18) à laver, et en une chambre de capture (20) dans laquelle sont retenues les saletés et les autres substances étrangères qui se sont détachées des articles (18) lors du lavage. La chambre de lavage (16) et la chambre de capture (20) sont en communication fluidique pour permettre la remise en circulation du flux de liquide nettoyant provenant de la chambre de lavage (16), traversant la chambre de capture (20) et retournant à la chambre de lavage (16). Une admission d'air (24) est prévue pour diriger l'air dans la chambre de lavage (16) depuis un point situé sous les articles (18). Lors de l'utilisation, la cuve de lavage (12) est remplie d'eau jusqu'à un niveau prédéterminé (26) et de l'air et dirigé par l'admission d'air (24) dans la chambre de lavage (16). En pénétrant dans la chambre (16), cet air forme des bulles qui passent à travers les articles (18) à laver et créent des tourbillons dans l'eau contenue dans la chambre (16), ce qui détache les saletés et les autres substances étrangères des articles (18) en cours de lavage. L'eau entrant dans la chambre (16) entraîne également un déplacement d'eau à l'intérieur de la chambre (16) et contribue à recréer un flux d'eau (22) de remise en circulation, provenant de la chambre de lavage (16), traversant la chambre de capture (20) et retournant dans la chambre de lavage (16). Ce flux (22) de remise en circulation de l'air entraîne avec lui les saletés et les autres substances étrangères qui étaient retenues dans la chambre de capture (20) et qui sont ainsi séparées du flux de remise en circulation (22).
