Description

    Field of the invention
  • The present invention relates to a washing machine, especially to a nozzle for supply of water in the washing machine.
  • Background of the invention
  • WO 2016/078714 discloses a washing machine comprising a detergent dispenser with compartments, structured for being filled with an amount of a detergent product. The detergent product is held in place until flushed by a flow of water into a washing compartment in the washing machine. Water is supplied to the compartments through holes in the top of the detergent dispenser.
  • A problem associated with such a supply of water is that such holes often are clogged by limestone and detergent products and the holes are inaccessible and difficult to clean. The entire detergent dispenser is often replaced when the holes are clogged, leading to an increased cost for the consumer.
  • Summary of the invention
  • An object of the present invention is therefore to obtain a washing machine that can be operated at a lower cost.
  • This object is achieved by means of a washing machine as defined in claim 1. More specifically, a washing machine comprises a nozzle, directed towards a detergent container adapted to be loaded with a detergent product, for supplying a water flow into the detergent container. The nozzle is connected to a water supply system in the machine, and comprises a connector for connecting to the water supply system, wherein the connector is configured to allow the nozzle to be removed from and re-connected to the water supply system.
  • This arrangement allows the user to remove and clean the nozzle if wholly or partly clogged by limestone and detergent products. Subsequently, the user may reconnect the nozzle to the washing machine.
  • Hereby is provided a washing machine that can be operated at a lower cost, since the nozzle easily may be removed from the washing machine, cleaned or exchanged and re-connected to the washing machine without necessity to replace the entire detergent dispenser. This action, users may easily do on their own without any help of a service technician.
  • The detergent container may be pivotable about a pivot axis between an upright position, in which the detergent container is upright to be loaded with a detergent product, and a tilted position, in which the detergent container is tilted for discharging of the detergent product into a washing compartment of the washing machine.
  • Hereby a smaller quantity of detergent products can be loaded into the detergent container, as the detergent product becomes very effectively discharged into the washing compartment of the washing machine.
  • This solution also makes it possible to flush the detergent container with water when the detergent container has been tilted and thereby more or less eliminating a film of residues on the container walls that needs to be cleaned manually.
  • The nozzle can protrude into the detergent container, both when the detergent container is in the upright and the tilted position.
  • Hereby splashing of water into the detergent dispenser and, more importantly, other neighboring detergent containers is prevented. Water supplied to the detergent container is discharged into the washing compartment being less likely to contamine neighboring containers..
  • The nozzle may be directed towards the detergent container from above when the detergent container is in the upright position.
  • The nozzle may be directed to produce a water flow along an inner wall of the detergent container when the latter is in the tilted position.
  • Hereby, most of the detergent product will follow the water flow from the nozzle into the washing compartment of the washing machine.
  • The nozzle may be openable, for instance by comprising two portions, that can be joined together by a locking device, for instance comprising a snap lock.
  • Hereby the two nozzle portions can be separated from each other by opening the locking device, and cleaning of a clogged nozzle becomes even more easy to perform.
  • The two nozzle portions may comprise an outer portion enveloping an inner portion, whereby a gap being formed therebetween, such that a water flow can be directed towards the detergent container.
  • The shape of the nozzle opening may be a curved gap, and this shape may be in conformity with a portion of the inner walls in the detergent container.
  • Hereby, the geometry of the nozzle provides a strong water flow directed towards the inner wall of the detergent container, which can rinse the detergent product from the detergent container, both when the detergent container is in the upright and tilted position. This allows a smaller amount of detergent product to be used, since the detergent product may be very efficiently dicharged into the washing compartment of the washing machine, leaving less residues in the container that the user needs to clean.
  • The nozzle connector may comprise an O-shaped rubber ring to obtain a leakproof seal between the nozzle and the washing machine.
  • Hereby is provided a simple and cheap solution to obtain a leakproof seal. The O-shaped rubber ring may easily be exchanged when worn out or broken by disconnecting the nozzle connector from the water supply system.

    Detailed description of the exemplary embodiments
  • Fig. 1 illustrates schematically a frontloaded washing machine 1 comprising a parallelepiped-shaped casing 3, a cylindrical washing compartment 5, indicated arranged inside the casing 3 and an electrically-powered motor (not shown), which is adapted to drive a drum in the washing compartment 5. A door 9 is attached to a front wall 7 of the casing 3 for watertight sealing of the washing compartment 5. Inside the casing 3, typically above the washing compartment 5, a detergent dispenser 11 is located, which is adapted for feeding a given quantity of detergent products into the washing compartment 5. The washing machine 1 may further comprise an appliance control panel 13 located on the front wall 7 of the casing 3, which allows the user to manually select a desired washing cycle among several available washing cycles. A fresh-water supply circuit (not shown) is connected to the water main for providing a flow of fresh water from the water main to the detergent dispenser 11 and/or to the washing compartment 5 according to the washing cycle selected by the user. Needless to say, other washing machine configurations are possible in the present disclosure.
  • With reference to Fig. 2, a detergent dispenser 11 may comprise a drawer 15, located inside the front wall 7 of the washing machine 1, typically above the washing compartment 5 and beside the appliance control panel 13. An outer handle 17, may be flush with the front wall 7 when the drawer 15 is closed. Two horizontal side walls 19 can be attached to the handle 17. Partitions 21 may be disposed inside the drawer 15, to which partitions 21 at least one detergent container 23 can be attached. In the illustrated case, four detergent containers 23 are used, having different sizes and intended uses. The detergent containers 23 may be adapted to be loaded with detergent products, such as detergents, bleaching agents, fabric softeners and like in the form of a powder, a liquid, or a tablet etc.
  • The detergent dispenser 11 may further comprise a frame 25, and a casing 27 attached to the frame 25. These parts 25, 27 can be made of a plastic material, such as polypropylene by injection molding. The drawer 15 can be movable inside the casing 27 in a substantially horizontally-orientated displacement direction d, and may as illustrated be tilted downwards once extending out of the machine.
  • As shown in Figs. 3 and 4, the casing 27 may comprise a box-shaped base portion 29, and a removable lid 31. The box-shaped base portion 29 may comprise two side walls 33, a rear wall 35, and an opening 37 opposite the real wall 35. The frame 25 is attached to the washing machine in the vicinity of the opening 37, and the drawer 15 can be inserted into the casing 27 through the opening 37. At least one nozzle 39 may be connected to a fresh water supply circuit 55 at the rear wall 35 of the casing 25. In the illustrated case four nozzles 39 are shown, having three different sizes, and conforming to the detergent containers 23 shown in fig 2, but other variations are possible. By changing the number and sizes of the detergent containers 23 and nozzles 39, a modular system can be created adapted to the size and type of the washing machine 1. It is also possible to adapt the size of the nozzle 39 to manage different water flow rates and container sizes. The lid 31 of the casing 27 may comprise notches 41 for the nozzles 39.
  • With reference to fig 2 and 5a-5d, the detergent container 23 may be shaped like a cup. The detergent container 23 can be made of a plastic material, such as polypropylene, by injection moulding. Polypropylene T20 is one example of a suitably used material. A pin 43 may be formed in opposing sides of the detergent container 23. By inserting the pins 43 into slots 45 of the partitions 21 in the detergent dispenser 11, the detergent container 23 becomes pivotable about a pivot axis (not shown) relative to the drawer 15 between an upright position (A), as seen in fig 5a and 5c, in which the detergent container 23 is upright to be loaded with a detergent product and a tilted position (B), as seen in fig 5b and 5d, in which the detergent container 23 is tilted for discharging of the detergent product in the detergent container 23 into the washing compartment 5 of the washing machine 1.
  • The detergent container 23 may have an asymmetrical shape in form of differently angled walls 47, 49, a front wall 47, facing the front of the drawer 15 and a rear wall 49, facing the interior of the casing 27. Thanks to the asymmetrical shape, the container may tilt automatically when filled with water to a predetermined level. The rear wall 49 can have a lip 51 curving away from the interior of the detergent container 23, which creates a jug-like configuration of the detergent container 23.
  • Figs 6a-6d illustrate the nozzle 39 as seen from its lower side. The nozzle 39 can be made of a plastic material, such as polypropylene, PP. It may comprise a connector 53 for connection of the nozzle 39 to a water supply circuit 55 at the rear wall 35 of the casing 27 (cf. fig 4). The connector 53 may be configured to allow the nozzle 39 to be removed from and re-connected to the water supply circuit 55, as seen in Fig 4.
  • The nozzle 39 may also comprise of two portions 57, 59, an inner portion 57 and an outer portion 59. The inner portion 57 may be smaller than the outer portion 59 and can be inserted into the outer portion 59, the outer portion enveloping the inner. A locking device may together attach the portions 57, 59 to each other. Thus obtained is a nozzle 39 that can be opened, disassembled, and each portion 57, 59 can be cleaned separately. Other options for obtaining an openable nozzle are possible, for instance using two similar halves that are snapped together.
  • The inner 57 and outer 59 portions can each comprise a base plate 60, 61, whose lateral edges have been folded upwards to form horizontal side walls 62, 63. According to fig 6c and the enlarged portion thereof, the locking device may be a snap lock formed by hooks 65 on the horizontal side walls 62 of inner portion 57 that are inserted into recesses 67 in the horizontal side walls 63 of the outer portion 59. It should be noted that this is only one example of a locking device, and other suitable embodiments can be used.
  • According to the illustrated embodiment of the nozzle in figs 6a-6d, the connector 53 may be an elongated tube, with one end attached to the base plate 60 of the inner portion 57 and the other end attached to the water supply system (not shown) by being connected to a water supply circuit 55 at the rear wall 35 of the casing 27. The tube of the connector 53 is then inserted into a tube of the water supply system where it fits tightly. The supply of water from the water supply circuit 55 to the nozzle 39, may be controlled by a separate valve (not shown) according to the selected washing cycles.
  • The connector 53 may be provided with a groove 69 for an O-shaped rubber ring to obtain a leakproof seal between the nozzle 39 and the water supply system (not shown) in the washing machine 1, although other solutions are possible. The O-shaped rubber ring may be attached on the elongated tube of the connector 53, for formation of a leakproof seal when the elongated tube is inserted into the water supply circuit 55. The O-shaped rubber ring can easily be replaced if worn out, and is accessed by disconnecting the nozzle connector 53 from the water supply circuit 55.
  • The front edges 71 of the base plate 61 at the inner portion 57 and the outer portion 59 can be curved and the horizontal side walls 63 may be equipped with a triangle shaped top 73, which are inclined relative the base plates 61, forming a curved part of the nozzle opening 75 (cf. fig 6d) that is directed towards the detergent container 23. Other solutions to provide a curved nozzle opening are possible.
  • The outer portion 59 may envelope the inner portion 57, a gap 75 being formed therebetween, such that the water flow can be shaped when directed towards the detergent container 23, as best seen in Fig. 6d. The geometry of the nozzle 39 provides a strong, water flow directed towards the inner wall of the detergent container 23, which can rinse the detergent container 23 from any remaining detergent product, both when the detergent container 23 is in the upright (A) and especiall y in the tilted (B) position. This allows a smaller amount of detergent product to be used, as almost all of the detergent product is dicharged into the washing compartment 5 of the washing machine 1. The water flow may be shaped to follow one inner wall of the container 23 and to proceed past corners at the ends of that wall and partly onto the adjoining lateral walls. This may eliminate any residue that could otherwise become stuck in the corners due to a weak water flow at those locations. It should be noted that such a nozzle configuration, providing a curved water flow that follows the shape of more than one wall in a detergent container, could also be useful in a machine where the nozzle is not removable, but is permanently connected to the machine. It is also not necessary to use a tilting container to make use of this shaped flow, this could be useful also in a normal, fixed solid detergent compartment that is open towards and optionally slopes towards its rear side where water and detergent enters the washing compartment.
  • The nozzle 39 may protrude into the detergent container 23, as seen in Fig. 5c, when the detergent container 23 is in the upright position A and the water flow from the nozzle 39 may be directed towards the detergent container 23 from above. The nozzle 39 may reach into the inner volume of the detergent container 23. Hereby water supplied from the nozzle ends up in the detergent container 23 and is prevented from splashing into other detergent dispensers 11 nearby. The curved lip 51 of the container rear wall provides a slightly lower end to allow the nozzle tip to enter in between the lateral edges of the container 23 when the drawer is pushed in.
  • The position of the nozzle 39 relative the detergent container 23 is changed when the detergent container 23 is tilted, as seen in fig 5d. The nozzle 39 may still protrude into the detergent container 23, and the front wall 71 and the horizontal side walls 73 of the nozzle 39 may abut against the front wall 47 and the side walls 79 at the inner side of the detergent container 23. Hereby the produced water flow from the nozzle 39 may be directed to follow the interior walls of the detergent container 23. Most of the detergent product will follow the water flow into the washing compartment 5 of the washing machine 1 and does not to any greater extent form a film of residues on the interior walls of the detergent container 23 that need be manually cleaned.
  • The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
  • It may also be noted that in one embodiment, the connector of the nozzle is devised to allow the nozzle to be removed from and re-connected to the water supply system but the nozzle is not openable. In another embodiment, the nozzle is openable but the connector of the nozzle fixedly connected to the water supply system. In a preferred embodiment, the connector of the nozzle is devised to allow the nozzle to be removed from and re-connected to the water supply system and the nozzle is openable.
