Description

The present invention relates to a laundry care appliance, e.g. a washing machine or washer-dryer, with a treatment room and a induction bowl.

Laundry care devices typically have a induction bowl for laundry treatment agents, such as detergents or fabric softeners, which is arranged in the front of the appliance housing and accommodates a detergent dispenser drawer that is accessible from the front. In some devices with automatic dosing function, the induction bowl drawer has at least one storage container for (usually liquid or gel-like) laundry treatment agents, as well as a device for automatically supplying stored laundry treatment agents to the treatment process. Generally, the laundry treatment agent is distributed together with water over the induction bowl or over an induction chamber, and is led flatly to a filling hose and flushed into the treatment room. However, there is a risk that the laundry treatment agent supplied will not be completely removed by the inflowing water and / or that detergent residues will remain on the bottom of the induction bowl / induction chamber and this will result in contamination.

From the US 7,249,473 A A washing-in unit is known which comprises two siphons of different sizes so that laundry treatment agents with different densities, such as in particular liquid or gel-like laundry treatment agents, can also be washed out satisfactorily from the washing-in unit.

From the US 9,487,903 B2 a washing-in unit with an upper part is known, the upper part having rinsing channels which direct fresh water in a targeted manner onto the side walls of chambers arranged in the washing-in unit in order to rinse out laundry treatment agents in the best possible way and to clean the chambers. In the above two documents, however, manual feeding of the laundry treatment agent into the induction unit by the user is necessary.

The WO 2010/040674 discloses a water-bearing household appliance ( 1 ) with a housing and a treatment room and one arranged inside the housing and controlled by a control unit (controllable automatic dosing system, the dosing system comprising at least one storage container and at least one feed pump arranged inside the storage container.

The EP 2 342 377 B1 also shows a washing machine for the automatic dosing of laundry treatment agents, in which a induction bowl drawer has at least one storage container, from which the laundry treatment agent is fed to a shaft and from there the water is fed to the treatment process. An opening for refilling the storage container is arranged in a room part of the storage container in such a way that the induction bowl drawer only has to be pulled out of the washing machine a short distance so that the opening is accessible.

In summary, there is a risk in the prior art that laundry treatment agent residues remain in the feed area to the treatment room. The residues can then lead to nucleation and unpleasant smells. The problem of not completely rinsing out the residues occurs in particular if there is insufficient water pressure at the inlet to the washing machine. However, from the point of view of the efficient use of water, a small water supply can also be desired.

The present invention is based on the object of designing a induction bowl of a laundry treatment device in such a way that optimal rinsing out of the laundry treatment agent or agents is ensured and residues thereof, in particular in the induction bowl, are avoided.

The invention solves this problem by the features of claim 1. Accordingly, a laundry care device comprises a treatment room and a washing-in bowl, the washing-in bowl having a washing-in bowl housing and a washing-in bowl drawer which can be inserted in the direction of insertion into the washing-in bowl housing, the Detergent dispenser has: at least one storage container for receiving a treatment agent, a powder chamber for manual dosing of treatment agent, a dosing chamber that has a water inlet and communicates with the treatment room, and a dosing device that is designed to remove treatment agents from the at least one storage container into the dosing chamber to promote, and wherein the metering chamber has a funnel shape so that its cross-section tapers in the flow direction of the water.

The laundry care device can be, for example, a washing machine or a washer dryer, it being in particular an automatically metering laundry care device, in particular a washing machine, preferably a front loading washing machine. The treatment room is typically a tub, in which a drum for holding laundry is rotatably arranged. The induction bowl forms one in particular Detergent unit in which laundry treatment agent is dosed, mixed with the water supplied and flushed into the treatment room. This is usually located in the upper left corner of the laundry care device. The induction bowl drawer and the induction bowl housing typically have a basic structure made of synthetic resin or plastic, which is produced in particular by means of an injection molding process. The induction bowl drawer can have a handle part for pulling out the induction bowl drawer and is preferably inserted into the induction bowl housing in such a way that the handle part is flush with a front side of the laundry treatment appliance when the induction bowl drawer is inserted.

The induction bowl has at least one storage container for a (usually liquid or gel) treatment agent, e.g. Liquid detergent and / or fabric softener, which is intended for automatic dosing. However, manual dosing should also be possible with automatically dosing devices (e.g. for laundry treatment agents with a special function such as mild detergents, detergents for the dark, impregnating agents, bleach, etc.). For this purpose, the powder chamber is provided, which can be filled with powdered laundry treatment agent as well as with liquid or gel-like laundry treatment agent or with agents for cleaning or maintaining the washing machine. The powder chamber is in particular a induction chamber, which is preferably supplied with water from a fresh water inlet from above. The at least one storage container is preferably a closed space with a closable opening for the manual refilling of laundry treatment agents. Refilling can be done by the user when the induction bowl drawer is pulled out of the laundry treatment device. The opening can be arranged so that it is accessible when the induction bowl drawer is pulled out. The induction bowl has in particular two storage containers.

The dosing chamber is a, in particular shaft-like, induction chamber, which is preferably supplied with water from a fresh water inlet from above and the treatment agent from the dosing device, preferably also from above. The water is preferably led from a cover of the induction bowl housing to the metering chamber. The water and the treatment agent are mixed or mixed together in the metering chamber. The metering chamber is preferably flowed through essentially vertically (i.e. from top to bottom). An opening for discharging the water and the laundry treatment agent to the treatment room is formed in the bottom region of the metering chamber. Furthermore, in advantageous embodiments, the metering chamber is small, in particular in relation to the at least one storage container and the powder chamber. The metering chamber preferably has a length in the direction of insertion of less than 10 cm and a width orthogonal to the direction of insertion of less than 5 cm. Funnel shape means that the flow cross-section of the metering chamber decreases in the direction of flow of water through the metering chamber. In addition, the funnel shape of the metering chamber can be designed such that it tapers in the direction of gravity (i.e. in the vertical direction). The funnel shape can be symmetrical or asymmetrical.

As a result, the water in the induction bowl is directed and a targeted rinsing of the dosing chamber with direct guidance of the water and the laundry treatment agent (channel guide) is achieved. As a result, a reduced risk of contamination of the induction bowl is achieved, since laundry detergent residues, in particular liquid detergent, are reliably rinsed out of the induction bowl. In addition, the deflection of the main flow in the edge region of the metering chamber, due to the shape of the funnel, ensures improved mixing or thorough mixing of the laundry treatment agent with the water. Furthermore, the laundry treatment agent in the metering chamber can be supplied to the main flow of the feed water, as a result of which a small amount of water and / or a lower water pressure is sufficient to supply the laundry treatment agent to the treatment room. This can reliably prevent laundry treatment agent residues from remaining in the induction bowl and contamination can be avoided.

In the above laundry care device, an area of the induction bowl in which the metering chamber and the powder chamber are arranged can be a wet area of the induction bowl and a remaining area of the induction bowl in which the at least one storage container is arranged can be a dry area of the induction bowl. The dry area is an area that is separated from the wet area in such a way that water does not leak during normal operation. Only in the wet area does a direct water wetting of the induction bowl take place, for example only on the left side of the induction bowl, and therefore contamination can only occur in the wet area (induction side). As a result, contamination in the drying area, in particular due to residues of laundry treatment agents, can be avoided. Since the wet area is spatially limited, for example to a maximum of 1/3, preferably a maximum of 1/4 of the base area of the induction bowl, the occurrence of contamination due to residues can only be limited to this area. Wet area and dry area are preferred in one Direction of insertion of the induction bowl drawer arranged side by side.

In an advantageous embodiment, the powder chamber and the metering chamber are arranged one behind the other in the direction of insertion. Arranged one behind the other means that the metering chamber is arranged in front of or preferably behind the powder chamber in the direction of insertion, or is arranged in a row with the metering chamber. Furthermore, the metering chamber can be arranged adjacent to the powder chamber. The fact that the metering chamber and the powder chamber (induction chambers) are arranged in series in the direction of insertion ensures that the induction bowl is separated into the wet and the dry regions. As a result, water wetting only takes place in the area of the metering chamber and powder chamber (wet area) arranged in series. In contrast, in the area of the induction bowl in which the at least one storage container is arranged (dry area), no water is conducted or guided, as a result of which contamination of the induction bowl can be further reduced.

In an advantageous embodiment, the metering chamber is arranged orthogonally to the direction of insertion next to the at least one storage container. In particular, the metering chamber can be arranged such that it adjoins the at least one storage container. If several storage containers are provided, the metering chamber can be arranged in such a way that it adjoins all storage containers. This ensures that the laundry treatment agent has to be conveyed from the individual storage containers only a minimal distance from the metering device in order to get into the metering chamber. In particular, the metering chamber is not arranged under the storage containers, but essentially at the same height as the at least one storage container. The metering chamber is preferably at the same height as the at least one storage container. As a result, the use of hoses or the like can be dispensed with, which lowers the material costs and the maintenance outlay and increases the operational safety. In addition, the energy required to convey the laundry treatment agents can be reduced and the efficiency of the laundry care device can be increased.

In an advantageous embodiment, the induction bowl has a first induction channel which connects the metering chamber and the treatment room. Furthermore, the powder chamber can be connected to the treatment room by a second induction channel. The first and possibly the second induction channel is a tubular structure which has a flow cross section and surrounds or surrounds the main flow of a medium flowing through it. In cross section, the first and possibly the second induction channel are preferably rounded, e.g. oval or round. The medium can drain through the first induction channel as a free-level drain or as a pressure drain. The dosing chamber and the connection of the first induction channel in the induction bowl is designed in such a way that the water and the laundry treatment agent are conducted directly from the first induction channel via a siphon into the treatment room, in particular into the drum. This enables a small funnel-shaped metering chamber in which the laundry treatment agent is collected and guided to the first induction channel. The “induction channel” here refers in particular to the section from the metering chamber or from the powder chamber to the respective siphon, to which a further hose or pipe section connects, through which the medium, i.e. a mixture of laundry treatment agent and water flows into the treatment room. The provision of a first induction channel and a second induction channel offers the advantage that the respective induction channel can be designed in accordance with the mixture to be conveyed (ie either the powder / water mixture or the gel-form or liquid laundry treatment agent / water mixture), in particular with regard to cross section, inclination, surface roughness an optimal rinsing result is achieved and contamination is avoided. Furthermore, this advantage is also achieved by directing the water from the metering chamber into the first induction channel, so that more targeted water distribution and flushing out is achieved even at low water pressure and the resulting lower flow rate.

In one of the above laundry care devices, the first induction channel can have a smaller flow cross section than the second induction channel. This ensures an increased flow rate of the water and also of the mixture of water and laundry treatment agent and thus an increased towing force in the first induction channel. This ensures that, in particular, the gel-type laundry treatment agent is sufficiently entrained or rinsed out with the water flow and that no residues can form. In addition, the first induction channel achieves a good induction with a high cleaning effect with the inflowing water, as a result of which deposits of media, in particular of laundry treatment agents, are avoided.

In an advantageous embodiment, the induction bowl can have a first induction channel which connects the metering chamber and the treatment room, the first induction channel up to a siphon being an integral part of the induction bowl housing or the induction bowl drawer. Here, “integral Part “in particular that the first induction channel is formed in one piece on the induction bowl housing or the induction bowl drawer. In particular, the first induction channel can be designed as part of the induction bowl housing or the induction bowl drawer as an injection molded part made of synthetic resin or plastic. This ensures a good connection of the induction channel to upstream and downstream components and contamination can be further reduced.

In an advantageous embodiment, the induction bowl has a first induction channel which connects the metering chamber and the treatment room, the first induction channel in a plan view of the induction bowl being able to run parallel to the direction of insertion and below the powder chamber and in particular up to a siphon opposite to the direction of insertion can be inclined in the direction of gravity. The siphon can be arranged in the induction bowl in the immediate vicinity of the front of the washing machine, behind the handle part of the induction bowl drawer. The inclination is preferably between 0 ° and 10 °. The incline ensures that an increased towing force of the water is ensured and deposits in the first induction channel are avoided. In addition, the separation of the induction bowl into the dry area and into the wet area is further ensured, so that water is only conducted in the wet area of the induction bowl. This means that water paths can be shortened and contamination avoided. In addition, the manufacturing costs are reduced due to material savings.

In one of the above laundry care devices, the induction bowl can have a first induction channel that connects the dosing chamber and the treatment room, and the dosing chamber can be connected fluidically to the side of the first induction channel. Connected by fluid technology here means that, for example, water which is fed into the metering chamber can enter the first induction channel from there. Because the metering chamber can be connected laterally to the first induction channel, one end of the first induction channel is exposed in its axial direction and can have a connection which can be used as access to the first induction channel, in particular for cleaning purposes. For example, the connection can be used as a further water supply in order to ensure a further flushing function of the first. In this way, a targeted flushing of the first induction channel can be carried out, which can further reduce or completely avoid contamination. Because the water flows laterally into the first induction channel in accordance with the lateral connection of the metering chamber to the first induction channel, the water must be deflected accordingly. The deflection of the water and the laundry treatment agent results in an improved mixing of the laundry treatment agent with the water and reduces the risk of contamination.

In an advantageous embodiment, the width of the metering chamber orthogonal to the direction of insertion is less than the length of the metering chamber parallel to the direction of insertion and / or less than the height of the metering chamber. The dosing chamber is therefore preferably relatively high and, in particular, elongated in the direction of insertion.

Furthermore, the metering chamber preferably has a smaller base area than the powder chamber, in particular it occupies at most 1/3, preferably at most 1/4, particularly preferably at most 1/5 of the base area of the powder chamber. It also preferably has a correspondingly smaller volume than the powder chamber, that is to say also a maximum of ¼. In particular, the metering chamber is significantly narrower in the direction transverse to the direction of insertion than the powder chamber, e.g. maximum half too wide. This creates a spatially limited wet area, which reduces the overall risk of contamination of the induction bowl. In addition, a targeted guidance of the water and the laundry treatment agent in the wet area is ensured, so that there are no deposits or residues of laundry treatment agent and / or water. In addition, an optimal use of space in the induction bowl is achieved.

In an advantageous embodiment, the metering device has at least one feed pump, so that a feed pump is assigned to each storage container, a suction side of the respective feed pump is positioned in the respectively assigned storage container, and a delivery side of each feed pump opens into the metering chamber. Each feed pump can be designed to convey or pump treatment agents from above into the metering chamber which is essentially at the same level as the storage container. If there is more than one storage container, at least one feed pump can be arranged in each of them, which can be controlled individually in order to feed certain doses or portions of the laundry treatment agent accommodated in the respective storage container to the metering chamber. Furthermore, the at least one feed pump can be designed such that it is immersed in the laundry treatment agent present in the storage container in order to convey it. In other words, the feed pump can be a submersible pump.

In particular, the suction side of each feed pump is arranged on the bottom of the respective storage container as far as is structurally possible, and the delivery side of the feed pump is located outside the storage container so that the feed pump delivers from above into the metering chamber. In addition, each feed pump is preferably arranged as close as possible to the metering chamber in order to keep the delivery distance as small as possible. For example, the feed pump is a gear pump. The control and power supply of each feed pump is preferably carried out via an electrical contact on the top of the metering device and is in the inserted state of the induction bowl drawer in contact with a corresponding contact of the washing machine, which can be arranged in particular on the cover of the induction bowl housing. This embodiment offers the advantage that the laundry treatment agent can be dosed automatically and individually. The use of submersible pumps offers the advantage that there is no need for a hose connection, which in turn ensures easier maintenance and assembly. The arrangement of the electrical components and contacts on the top of the dosing device ensures that they are protected from moisture.

In one of the above laundry care devices, the induction bowl drawer can include the at least one storage container, the metering device and the powder chamber for manual metering. The induction bowl drawer preferably comprises one or more components which are made of plastic by means of injection molding, the powder chamber and the at least one storage container being formed therein. The dosing chamber can also be part of the induction bowl drawer, in an advantageous embodiment it is part of the induction bowl housing. The induction bowl drawer is in fluidic contact with the induction bowl housing in such a way that fresh water and laundry treatment agent, which is supplied via the metering device, are introduced into the metering chamber from above. More precisely, a delivery side of the dosing device is positioned together with the dosing device in the induction bowl drawer in such a way that, when the induction bowl drawer is inserted into the induction bowl housing, the delivery side of the dosing device comes to rest over the dosing chamber without contact Dosing device with the dosing chamber is necessary. Consequently, the fluidic connection of the induction bowl drawer to the induction bowl housing is simplified in that the dosing chamber and the first induction channel are formed in the induction bowl housing and the laundry treatment agent and the fresh water are supplied to the dosing chamber from above.

In one of the above laundry care devices, the metering device can be detachably inserted from above onto the dispenser drawer. The metering device can comprise at least one feed pump, which extends downward from a main body of the metering device in such a way that it is immersed in the respective storage container in a laundry treatment agent contained therein. Furthermore, the metering device can be designed such that if a plurality of storage containers are provided, it extends at least partially over them, so that a feed pump associated with the respective storage container is held by the metering device. The fact that the metering device can be removed from the induction bowl drawer enables easy repair, good accessibility to the at least one storage container and thus an improved cleaning possibility. The induction bowl drawer can be cleaned in the dishwasher, for example, since all electronic components can be removed from the induction bowl drawer by removing the metering device.

In one of the above laundry care devices, the at least one storage container can have a cover that includes an opening for receiving the metering device, and the opening of the cover can have an outline shape that corresponds to the outline shape of the metering device, so that the metering device when inserted into the treatment agent drawer is held so that twisting or displacement of the metering device is prevented. The at least one storage container can have a lid which, in addition to the openings for the manual refilling of laundry treatment agents, has a cutout or opening into which the metering device can be inserted. By starting the at least one feed pump, a torque thereof can cause the metering device to shift. If the metering device is inserted into the recess b of the storage container, the torque of the feed pump can be absorbed by the special shape of the opening and thus a displacement of the metering device can be prevented. Furthermore, an increased accuracy of fit of the dosing device in the induction bowl drawer is ensured, which ensures the reliable and precise feeding of laundry treatment agents into the dosing chamber. In addition, the special shape prevents a user from inserting the dosing device into the induction bowl drawer in the wrong position.

In an advantageous embodiment, the induction bowl housing can comprise at least the dosing chamber and a first induction channel which connects the dosing chamber and the treatment room. The induction bowl housing comprises, in particular, an integral component which is produced from plastic by means of injection molding. This ensures a safe connection to the washing machine system. Further must water-carrying parts of the induction bowl housing cannot be moved, which increases operational safety.
