Definitions

  • the present invention relates to a dosing unit for use in an automatic dosing system of a water-bearing household appliance, and a respective water-bearing household appliance with an automatic dosing system.
  • Known water-bearing household appliances typically have a dosing system, which consists of a chamber for storing a single dose of detergent.
  • the user of the dishwasher has to fill the chamber with the detergent each time before starting a washing cycle. This is inconvenient for the user.
  • such systems bear the risk that the user does not fill in the correct amount of detergent or forgets to fill in detergent at all. This can lead to bad or undesirable cleaning results.
  • an automatic dosing system is available, which automatically doses the correct amount of detergent at the correct timings during a washing cycle.
  • US 2019/133411 describes a metering device for dispensing shaped cleaning-agent bodies into a washing chamber of a domestic dishwasher, comprising a reservoir, which is designed to hold a filling of the shaped cleaning-agent bodies and has a transfer opening in a region of the bottom of the reservoir, and a transport device for actively transporting the shaped cleaning-agent bodies from the transfer opening of the reservoir into the washing chamber.
  • DE 10 2017 208013 describes a dosing device for dispensing cleaning agent shaped bodies into a washing chamber of a dishwasher, with a storage container which is designed to hold a bed of cleaning agent shaped bodies and has a transfer opening in one area of its base, and a transport device for actively transporting the cleaning agent shaped bodies from the transfer opening of the storage container into the washing compartment.
  • US 2007/163968 describes a dispenser that includes a flexible pouch filled with treatment chemicals and an osmotic membrane.
  • the dispenser is placed in the process water system. Water passing through the membrane increases internal pressure, which forces chemical into the process water system.
  • a dosing unit for automatically dosing a dosing amount of a solid detergent provided by a storage cartridge for storing a bulk of the solid detergent, for use in an automatic dosing system of a water-bearing household appliance.
  • the storage cartridge comprises a reversibly deformable container with an outlet, wherein the dosing unit is configured so that detergent of the bulk is transported towards the outlet by deforming the container according to a predefined pattern in time for a peristaltic transport of detergent.
  • a dosing device is attached to the storage cartridge on the outlet for separating the dosing amount from the bulk and releasing the separated dosing amount.
  • the dosing unit includes the storage cartridge and the dosing device.
  • the container is arranged such that a bottom side of the container, when the dosing unit is oriented as intended for use, has a slope towards the outlet with respect to a horizontal direction that is in the range of -45° to 15°.
  • the container includes at least three actuation sections distributed along the bottom side, wherein each actuation section is configured for being lifted by an external actuation member.
  • the solid detergent may be any kind of detergent, that is, a chemical formulation that dissolves, at least partially, in a washing liquor for treating articles and is suitable for enhancing the treatment of the articles by the washing liquor.
  • the detergent includes enzymes, a bleaching agent, a softening agent, a rinse aid, and/or further detergents.
  • the solid detergent may be provided in any form, that is, as powder, as tablets, as pellets, or the like.
  • the dosing unit comprises several elements, such as the dosing device and the storage cartridge, even if not mentioned explicitly.
  • the elements of the dosing unit are preferably made from polymeric materials which are suitable for injection molding. Additionally, the elements may be made from metal and/or a composite material and/or the elements may be coated.
  • the container will assume a certain shape when it is at rest, due to the gravity acting on it and on the bulk of detergent it stores.
  • This shape is referred to undeformed shape or relaxed state in the following.
  • deforming the container in particular by lifting certain sections or portions of a bottom of the container starting from the undeformed shape, local minima and maxima, or bumps, can be generated at an inner side of the container.
  • a local maximum is connected by the side wall of the container with the next local minimum along a gradient.
  • the shape the container assumes when being deformed is a function of at least the mechanical properties of the container and of the weight of the bulk of detergent stored therein.
  • the bulk of detergent forms a loose filling, such that it will rearrange when the shape of the container is changed due to such deformation.
  • portions of the bulk resting at a local maximum in the container try to move towards a local minimum, driven by gravity, in order to minimize the potential energy.
  • an effective transport of detergent inside the container is achieved.
  • the bottom side of the container can be considered as forming a transversal wave which travels towards the outlet, wherein a wave front of the wave "pushes" detergent in its moving direction, when being deformed according to the predefined pattern in time.
  • the predefined pattern in time corresponds to a propagating transversal wave.
  • this kind of transport is referred to as peristaltic transport of detergent.
  • the dosing device is attached to an opening or outlet of the storage cartridge, which is in communication with the outlet of the container.
  • the dosing device may be snapped onto, clipped to, glued to, welded to, and/or screwed onto the storage cartridge.
  • the dosing device is implemented for separating a dosing amount of the detergent from the bulk.
  • the dosing device includes an element, such as a scoop, that allows for taking, from the bulk, the dosing amount.
  • the separated dosing amount needs not be physically separated from the bulk. It is sufficient when it is arranged such that the separated dosing amount forms the part of the detergent that will be dosed the next time when the dosing unit is actuated for dosing.
  • the dosing amount includes between 0.5 g to 15 g of detergent.
  • the dosing amount may be exactly one detergent tablet.
  • the peristaltic transport transports detergent as close to the dosing device as is necessary for the dosing device to separate the dosing amount.
  • the dosing device has a certain range and the detergent is transported into that range.
  • the dosing unit has the advantage that it can be manufactured at low cost, such that when the storage cartridge runs empty of detergent, the whole dosing unit can simply be replaced. A refilling of the storage cartridge may be possible, but is not necessary. It can be very convenient for a user of the water-bearing household appliance with the automatic dosing system to simply replace the whole dosing unit, which may be provided with different kinds of detergent for different applications or different treatment programs.
  • the container has an elongated shape and the outlet is arranged at a face side of the container.
  • the container is arranged such that a bottom side of the container, when the dosing unit is oriented as intended for use, has a slope towards the outlet with respect to a horizontal direction that is in the range of -45° to 15°.
  • a negative value of the slope means that the bottom side is tilted towards the outlet, such that a gravitational force acting on the detergent includes a force component directed towards the outlet, which assists in the peristaltic transport.
  • the container includes at least three actuation sections distributed along the bottom side, wherein each actuation section is configured for being lifted by an external actuation member.
  • An actuation section comprises, for example a flexible joint joining two stiff elements, or a reinforced section of a thin foil.
  • the dosing unit is intended to be used in an automatic dosing system of a water-bearing household appliance, such that the external actuation member may push the container upward at the actuation sections.
  • a sealing element when the plug is in the closed position, a sealing element is engaged such that the dosing device is sealed impermeably to fluids of all kinds.
  • Fig. 2 shows a schematic view of a second example of a dosing unit 100.
  • the storage cartridge 110 includes a support structure 111, which is implemented as an essentially not deformable case for containing the container 114, which is made from a flexible foil.
  • the support structure 111 includes holes or slits which allow an external actuation member 24 to reach into the support structure 111 for deforming the container 114.
  • the dosing unit 100 is configured for dosing a detergent tablet 102 as the dosing amount 122.
  • the bulk 112 includes a plurality of detergent tablets 102.
  • the external actuation member 24 By reaching into the support structure 111, the external actuation member 24 temporarily lifts the container 114 at the actuation sections 118. Therefore, bumps are formed in the container 114, and detergent tablets 102 arranged in the actuation section 118 are lifted upward.
  • the detergent tablets 102 arranged on the slope that is induced in the container 114 by the bump will slide in the direction of the gradient along the slope, if there is free space, driven by gravity G, as indicated by arrow P for one detergent tablet 102.
  • the storage cartridge 110 On the side of the outlet 116, the storage cartridge 110 includes a taper section 115, which is implemented as a geometric feature having a negative slope towards the outlet 116. Thus, detergent tablets 102 resting on the taper section 115 will slide towards the outlet 116 and the dosing device 120 arranged there, if there is some space.
  • the three actuation sections 118 shown in Fig. 2 are merely an example, and there may be more than three actuation sections 118 and/or they may be distributed different than shown here along the bottom side.
  • the separated detergent tablet 102 is transported by the scoop 130 to a receiving chamber 142 formed in the plug 140.
  • the detergent tablet 102 is stored in the receiving chamber 142 and forms the dosing amount 122 of detergent in this case.
  • the detergent tablet 102 cannot escape the receiving chamber 142 back into the storage cartridge 110.
  • the plug 140 has, on its front face facing away from the storage cartridge 110, an engaging section 144 for engagement with a driving element of an external driving unit 22 (see Fig. 3 ). Further, the plug 140 has an external thread 146 that is engaged with an internal thread 126 formed in the dosing device 120, such that the plug 140 can displaced laterally by screwing. Particularly, the plug 140 is shown in Fig. 3 in a closed position, in which the dosing device 120 is sealed impermeably.
  • the outlet 124 formed in the dosing device 120 is cleared and the dosing amount 122 stored in the receiving chamber 142 is released from the dosing device 120.
  • the dosing of the dosing amount 122 from the dosing unit 100 is performed. In the example of Fig. 2 , only rotational actions are needed for this.

  • the driving unit 22 is configured for engaging with the dosing device 120 attached to the storage cartridge 110 an operate it, such that the dosing amount 122 (see Fig. 1 or 2 ) is released from the dosing unit 100.
  • the actuation member 24 is configured for actuating the container 114 (see Fig. 1 or 2 ) such that peristaltic transport of the detergent stored in the container 114 towards the dosing device 120 occurs.
  • the automatic dosing system 20 is triggered or operated by a control unit of the dishwasher 1.
  • Fig. 4 shows a schematic block diagram of an example of a method for dosing a dosing amount 122 (see Fig. 1 or 2 ) of a solid detergent from a dosing unit 100, for example the dosing unit 100 described with reference to Fig. 1 or 2 .
  • the dosing unit 100 includes a storage cartridge 110 for storing a bulk 112 of the solid detergent.
  • a reversibly deformable container 114 of the storage cartridge 110 is deformed according to a predefined pattern in time for transporting detergent from the bulk 112 towards an outlet 116 of the container 114.
  • the dosing amount 122 is separated from the bulk 112 by a dosing device 120.
  • the separated dosing amount 122 is released.
  • FIG. 5 door 3 is shown in the open position. By swiveling about an axis 5 at a lower edge of door 3, the door 3 can be opened or closed. With the door 3, an opening 6 of the tub 2 for inserting dishes into the washing chamber 4 can be opened or closed.
  • Tub 2 comprises a lower cover 7, an upper cover 8 facing the lower cover 7, a rear cover 9 facing the closed door 3 and two side covers 10, 11 which face each other.
