Description

DOSING OF A SOLID DETERGENT IN A DOMESTIC DISHWASHING MACHINE

The present disclosure relates generally to the dosing of a solid detergent into a domestic dishwasher.

In personal household dishwashers, technological development is progressing toward providing the dishwasher with a magazine capable of storing a larger amount of solid detergent. In the case of liquid rinse aids, there are already solutions for storing a sufficient amount of liquid for multiple operating cycles of a dishwasher. For actual detergents, often in the form of compressed detergent tablets or pourable detergent powder, storage solutions with automatic dosing are also increasingly being explored.

For the prior art relating to solutions for the storage and dosing of detergents in powder or tablet form in domestic dishwashers, see, for example, DE 10 2014 115 512 A1; WO 2009/022223 A1; CN 111743495 A; Reference may be made to DE 10 2019 009 054 A1.

Detergent tablets are particularly user-friendly. When the user needs to put the detergent powder into the magazine of the powder dosing unit, it may easily happen that the user spills some of the detergent powder. In general, there is no need to fear this inconvenience when using detergent tablets. However, especially for detergent tablets that are not spherical, oval or disc-shaped, in order to ensure that the dishwasher can generally remove a defined number of detergent tablets (typically one tablet per operating cycle) during operation, the magazine It is necessary to store detergent tablets in the manner laid out in A magazine for the organized storage of detergent tablets may form, for example, one or more stacked chutes, in which one detergent tablet can be stored stacked on top of another detergent tablet (see, e.g. DE 10 2019 009 054 A1). ).

Another magazine structure that should be considered more closely within the scope of the present disclosure is an annular magazine structure that allows specifically metered portions of detergent tablets or detergent powder to be stored in an annular arrangement. Documents WO 2009/022223 A1 and CN 111743495 A, mentioned at the outset, disclose an annular magazine solution having a plurality of storage compartments distributed along a ring, inside each of these compartments a detergent tablet or powder portion can be stored. According to WO 2009/022223 A1, the detergent accommodated in the storage compartment is gradually washed out of the storage compartment by a stream of water. If the various bins of the magazine are not completely sealed from each other (which can generally be difficult to achieve), sprays can reach portions of detergent stored in different bins, causing undesirable lumps and agglomeration. CN 111743495 A provides a slider for pushing the prepared detergent tablets from the storage compartment laterally out of the storage compartment. These sliders incur significant additional costs in terms of construction and control.

It is an object of the present invention to provide a dosing system which is intended for use in a dishwasher and is suitable for a dishwasher, which is distinguished by a simple structure and a simple principle of operation.

In order to achieve the above object, the present invention provides a household dishwasher, wherein the dishwasher is rotatable about a pivoting axis of a horizontal door adjacent to the floor in order to close a dishwashing container and a dishwashing chamber formed in the dishwashing container a door mounted on the dishwashing container, and a dosing system for the solid detergent disposed on the door. The dosing system comprises: a rotor disposed in a magazine chamber rotatably about a rotor axis, the rotor circumferentially distributed about the rotor axis, the rotor defining a plurality of storage compartments open radially outward; an loading opening in the perimeter wall of the magazine chamber, wherein each storage compartment can be individually and continuously moved to a position radially opposite the loading opening by rotation of the rotor to empty the said storage compartment through the loading opening; and a chute connected to the magazine chamber through the input opening. The rotor is configured such that the plane of rotation of the rotor is arranged substantially parallel to the major plane of the door, the portion of the solid detergent stored in the storage compartment when the door is closed and one of the storage compartments is moved to a position radially opposite the dosing opening. The dosing opening is arranged under the rotor so that the s can fall from the storage compartment in question into the chute through the dosing opening only by gravity.

According to this solution, it is sufficient to rotate the rotor into a position in which one of the storage compartments is radially opposite the input opening. In this dosing position of the storage compartment in question, the portion of the solid detergent located therein can fall radially out of the storage compartment and fall into the chute through the dosing opening only by the force of gravity. The storage compartment does not need to be flushed with a water jet, nor is it necessary to use an additional pusher to laterally (horizontally) push some of the solid detergent out of the storage compartment. The input opening can be formed, for example, in a chamber boundary wall of the magazine chamber which is formed by the chamber housing and surrounds the rotor in an annular manner.

In some embodiments, the rotor is installed in the door with a plane of rotation of the rotor substantially parallel to a major plane of the door, and the chute is adjacent the magazine chamber below the magazine chamber. Accordingly, the term “beneath” refers to the closed state of the door. Typically, a door is mounted to a dishwashing container of a dishwasher so as to be pivotable about a horizontal pivoting axis proximate to the floor. Therefore, a closed door faces vertically, and the door must be rotated horizontally to open it. Thus, in order to deliver the detergent by gravity from the storage compartment to the chute, the chute must be arranged under the rotor in the direction towards the pivot axis close to the bottom. By stepwise further rotation of the rotor, detergent portions can be continuously transferred from each storage container into the chute.

The solid detergent may be in pourable powder or tablet form. Such detergent tablets are usually made into a predetermined space by compacting one or more powdered starting materials (in some cases containing various active substance compositions). Detergent tablets of approximately rectangular shape are commonly found, which, when viewed from a large side, have an approximately rectangular outline, and have a length and width when viewed from a large side that are greater than a thickness when viewed from a small side. However, the present invention is, of course, not limited to such rectangular detergent tablets; The use of other types of detergent tablets is likewise contemplated within the scope of the present disclosure. When a portion of a solid detergent is referred to herein, the portion consists of a predetermined number of such detergent tablets, for example a single detergent tablet. In the case of powder detergent, the portion consists of the amount of powder introduced into the storage compartment in question. This amount can be measured specifically, particularly when the magazine has been filled with detergent by the manufacturer, or it can be measured eye-to-eye, for example when the consumer is hand-introduced for the first fill or refill.

In some embodiments, the chute defines a dropping section extending particularly substantially linearly downward from the inlet opening to the outlet opening for free falling a portion of the solid detergent in the chute, the chute at the outlet opening from the door into the dishwasher It is open. In this embodiment, a portion of the solid detergent removed from the magazine may fall through the input opening and through the entire chute to the discharge opening and out of the discharge opening only under the influence of gravity without additional auxiliary devices. After exiting the discharge opening, some of the solid detergent may be sprayed into the dishwashing room or absorbed and dissolved by the collected dishwashing water.

In some embodiments, the chute is arranged to be immovable relative to the input opening. For example, the dosing system includes a common housing component that simultaneously defines at least a portion of the magazine chamber and at least a portion of the chute.

In some embodiments, the dosing system includes a drive mechanism for rotationally driving the rotor such that the direction of rotation of the rotor can be changed. Also provided is a control unit configured to control the drive mechanism by changing the rotational direction of the rotor. With these measures, the dosing system provides structural and control-related specifications for driving the rotor by changing the direction of rotation.

Changing the direction of rotation of the rotor can be used for various purposes. For example, detergent tablets can easily jam or remain in the storage compartment so that they do not immediately fall out of the storage compartment once the storage space is moved to a location opposite the dosing opening on the first access stroke. Moving the storage compartment over the dosing opening one or more times may help to free the wash tablets from the storage compartment even in such cases. Accordingly, some embodiments are configured such that the control unit controls the drive mechanism such that the storage compartment moves back and forth at least once to empty one of the storage compartments. In particular, the storage compartment in question is at least partially movable past the input opening at least once and then moved again to a position radially opposite the input opening.

Alternatively or additionally, it may be useful to be able to change the direction of rotation of the rotor to ensure that the storage compartment has actually been emptied. Accordingly, in some embodiments, it is provided that the dosing system includes a sensor system that allows the presence of a portion of the solid detergent in the storage compartment to be detected before the storage compartment is moved to an empty position (doing position) relative to the dosing opening. wherein the control unit is configured to control the drive mechanism such that after one of the storage compartments is moved to the empty position, the storage compartment is moved back into the sensing range of the sensor system. When the storage compartment is moved back, the sensor system can determine whether some of the solid detergent remains in the storage compartment. Otherwise, if the storage compartment is identified as full before it is moved to the empty position, it is certain that the storage compartment has been emptied properly. If so, the control unit may, for example, display a visual or/and audible warning message to the user and/or make a further attempt to free the same storage space and/or attempt to free the next storage space.

Some embodiments include a drive mechanism for rotationally driving the rotor, a control unit for controlling the drive mechanism, and a sensor system coupled to the control unit and capable of detecting whether a portion of the solid detergent is present in the storage compartment. The control unit controls the drive mechanism to empty the other of the storage compartments when it is detected that some of the solid detergent remains in one of the storage compartments after the storage compartment has been moved at least once to the empty position relative to the dosing opening. to move to location. Thus, even if one of the storage compartments cannot be emptied successfully (eg if the cleaning tablets do not stick and fall off under the action of moisture in that storage compartment, etc.), the functioning of the dosing system is maintained. If the storage compartment cannot be emptied even after a predefined number of evacuation attempts, the dosing system attempts to empty the next storage compartment. Therefore, there is no need to interrupt the running of the dishwashing program.

If the control unit detects that the storage compartment cannot be emptied after one or more attempts, the control unit may emit an audible and/or visual indication for the operator. This indication constitutes a request to the operator to clean the magazine and remove the aggregated amount of detergent.

Hot steam and/or mist from the dishwasher may enter the chute or/and magazine chamber. Hot vapors or sprays can be detrimental to detergents stored in annular magazines. For example, the detergent may partially dissolve to form clumps or stick to the walls of the storage compartment. The ingress of hot moisture may be counteracted by the flow of blowing air into the magazine chamber and/or into the chute. Accordingly, some embodiments provide that the dosing system includes a blower for creating a stream of blowing air into the magazine chamber and/or into the chute.

The blower may be in a direct blow air supply connection with the chute. Direct here means a blow air supply connection from the impeller chamber in which the blower's impeller is arranged, directly to the chute without first passing through other parts of the dosing system, in particular the magazine chamber. In another embodiment, the blower is provided in direct blowing air supply connection with the magazine chamber. Air blown from there can enter the chute. In such an embodiment, there is a blow air supply connection between the blower and the chute via the magazine chamber.

The suit can be selectively blocked and released. To this end, the dosing system is arranged so as to be movable in a particularly translational manner between a blocking position for blocking the chute so that a portion of the solid detergent does not fall into the discharge opening and a release position for releasing the chute so that a portion of the solid detergent does not fall into the discharge opening A blocking member may be included. The blocking member may be configured to close substantially the entire chute cross-section of the chute, particularly in the blocking position. Thus, when the chute is closed (ie when the blocking member is in the blocking position), undesirable ingress of vapors or/and sprays into the part of the dosing system located above the blocking member can be prevented. However, the chute must be opened so that some of the detergent removed from the magazine for dosing can reach the end of the chute and from there to the dishwasher's dishwasher. With the chute open, it is recommended to operate the blower to keep the hot steam and/or spray as far away from the magazine as possible. Accordingly, an embodiment of the present invention provides a control unit for a blower, wherein the control unit is configured to control the blower to produce blowing air at least during a phase in which the blocking member is in the released position.

Of course, it is also possible to control the blower so that the blocking member is in the blocking position to additionally generate the blower with the chute closed. This is because it cannot be excluded that a defective seal could cause vapor and/or spray to enter the magazine chamber. Therefore, it can be convenient to operate the blower even when the chute is blocked. For example, in some embodiments it would be contemplated to run the blower substantially continuously during the entire wetting phase of the operating program of the dishwasher, and additionally, if desired, to operate the blower during the subsequent drying phase of actively drying the dishes by the dishwasher. can

According to some embodiments, the dosing system comprises a pusher for urging a portion of the solid detergent stored in one of the storage compartments radially outward in the dropping direction. The pusher may be, for example, in the form of a spring actuated pusher or an electromagnetically actuated pusher.

In some embodiments, the dosing system comprises an electrically controllable drive mechanism for rotationally driving the rotor and in particular the pivotally mounted magazine cover to close access to the magazine chamber. The magazine cover can be removed from the magazine chamber without disconnecting the mechanical drive connection between the drive mechanism and the rotor, which access allows access to each storage compartment to fill a portion of the solid detergent once the magazine cover is removed.

The rotor may be secured against axial removal from the magazine chamber by one or more fixing members (eg screws), which require an auxiliary tool to release.

According to a further aspect, the present invention provides a dosing system for a household dishwasher, the dosing system comprising a rotor disposed or arrangable in a magazine chamber so as to be rotatable about a rotor axis, wherein the rotor is formed by a cup side and a cup base. defining a central cup portion, and a plurality of storage compartments circumferentially distributed radially outwardly of the central cup portion, arranged to axially overlap the cup sides, each storage compartment containing a portion of the solid detergent; Rotor, an electrically controllable drive mechanism for rotationally driving the rotor, wherein, in preparation for operation of the dosing system, an electromechanical or/and mechanical component of the drive mechanism, in particular an electric motor or/and a reduction gear, are accommodated inside the cup so that they are placed in the cup A dosing system for a domestic dishwasher comprising a drive mechanism at least partially hidden under a base is provided. Receiving the components of the drive mechanism in the central cup portion is advantageous in reducing the overall height of the dosing system. In particular, the inner perimeter of the cup side can be used to provide teeth in engagement with a drive pinion of a drive mechanism arranged in the central cup portion.

Another aspect of the present invention is a dosing system for a domestic dishwasher, wherein the dosing system is a rotor disposed or operable in a magazine chamber so as to be rotatable about a rotor axis, wherein the rotor is circumferentially about the rotor axis. A rotor that is distributed and defines a plurality of storage compartments each containing a portion of the solid detergent, the photoelectric sensor system capable of detecting the presence of a portion of the solid detergent within the storage compartment, the sensor system having a radius into each storage compartment A dosing system for a domestic dishwasher comprising a photoelectric sensor system configured to illuminate a sensor light beam directed from radially inward to radially outward or radially outward to radially inward is provided. Illuminating a light beam directed radially inwardly or through the storage compartment at a relatively small angle (acute angle) to the radial direction causes the light emitting or/and light receiving components to be radially inside the storage compartment within the axial height range of the storage compartments. It allows to be arranged directionally inwardly and/or radially outwardly. The sensor system therefore does not require additional installation space in the vertical direction. This is advantageous in consideration of the limitation of the installation space imposed by the door of the household dishwasher in the direction of the thickness of the door in general.

Each of the storage compartments is radially defined therein by a wall portion of the rotor having a window opening formed therein, and the sensor system is configured to direct the sensor light beam through the window opening in each storage compartment.

Another aspect of the present invention is a dishwashing container, a door mounted on the dishwashing container so as to be pivotable about a horizontal door pivot axis close to the floor to close a dishwashing chamber formed in the dishwashing container, and a door for solid detergent. A domestic dishwasher is provided having an arranged dosing system. The dosing system comprises a magazine for storing the solid detergent, a chute for conveying a portion of the solid detergent removed from the magazine by gravity to the discharge opening, and a chute for opening the chute so that a portion of the solid detergent can fall through the discharge opening. blocking element arranged so as to be movable back and forth in particular translationally between the free position and the blocking position blocking the chute in a blocking position located below the starting point of the chute so that no part of the solid detergent cannot fall through the outlet opening; An electrically controllable actuator to actuate, and while the dishwasher's dishwashing program is running, the blocking member is in the blocking position for most of the program, but when removing a portion of the solid detergent from the magazine, the removed portion is the chute. and a control unit configured to control the actuator so that it can freely fall within the chute from the starting point of the to the discharge opening.

In this aspect of the invention, it is ensured by the control unit that the free fall of the detergent portion transferred from the magazine into the chute is not temporarily stopped by the blocking member since it is still in the blocking position. Instead, the control unit ensures that the blocking member is in the unlocked position when the detergent portion removed from the magazine falls into the chute. Thus, the detergent fraction can fall through the entire chute at once. To this end, the control unit is suitably programmed or configured such that the blocking member is transferred from the blocking position to the unlocked position at an appropriate time before the detergent portion delivered from the magazine to the chute reaches the point where the blocking member is. As soon as the detergent portion has passed the blocking member, the blocking member can immediately move back to the blocking position.

Another aspect of the present invention is a dishwashing container, a door mounted on the dishwashing container so as to be pivotable about a horizontal door pivot axis close to the floor to close a dishwashing chamber formed in the dishwashing container, and a door for solid detergent. A domestic dishwasher is provided having an arranged dosing system. The dosing system comprises a magazine for storing the solid detergent, a chute for conveying a portion of the solid detergent removed from the magazine by gravity to the discharge opening, and a chute for opening the chute so that a portion of the solid detergent can fall through the discharge opening. a blocking member arranged to be movable back and forth particularly in a translational manner between a free position and a blocking position blocking the chute so that a portion of the solid detergent cannot fall through the outlet opening, an electrically controllable actuator for driving the blocking member, and and a control unit configured to control the actuator to move the blocking member from the blocking position to the free position without starting a dish washing program of the dishwasher in response to the received operator's predetermined operation command. This function of the control unit causes the blocking member to be moved to the unlocked position for cleaning purposes, allowing the user to reach all areas of the suit with a cleaning tool, for example a brush or toothbrush.

According to another aspect of the present invention, there is provided a dosing system for a domestic dishwasher comprising: a magazine for storing solid detergent; a chute for conveying by gravity a portion of the solid detergent removed from the magazine to an outlet opening; Between a free position that opens the chute so that a portion of the solid detergent can fall through the outlet opening and a shutoff position that blocks the chute in a blocked position that is located below the starting point of the chute so that a portion of the solid detergent cannot fall through the outlet opening a sensor system associated with the chute, in particular a photoelectric sensor system, the sensor system being configured to check the chute in the chute area above the blocking point for the presence of solid detergent includes

The sensor system allows the suit to be scanned using the sensor to detect a drop of a portion of detergent removed from the magazine or the presence of a portion of detergent that is stationary in a (blocking) blocking member. Accordingly, the functional reliability of the dosing system can be increased. The sensor system makes it possible to determine during the dosing operation whether the detergent fraction has actually entered and/or passed through the chute. For example, a sensor system may operate on the functional principle of a light barrier. A mechanical sensor with a sensor arm protruding into the drop path of the detergent in the chute can be considered as an alternative to the test light beam irradiated onto the chute.

Another aspect of the present invention is a dosing system for a domestic dishwasher, wherein the dosing system is a rotor disposed or operable in a magazine chamber so as to be rotatable about a rotor axis, wherein the rotor is circumferentially about the rotor axis. a rotor which is distributed and defines a plurality of storage compartments, each containing a portion of the solid detergent, a chute conveying by gravity a portion of the solid detergent removed from one of the storage compartments to the discharge opening, a sensor system, in particular a photoelectric A sensor system comprising: a sensor system capable of detecting the presence of a portion of solid detergent in one of the storage compartments and independently of it capable of detecting the presence of a portion of solid detergent in the chute. In this aspect of the invention, the sensor system is configured to perform both scanning at least one of the storage compartments for the presence of a detergent portion and monitoring the chute for entry or passage of the detergent portion.

In the last-mentioned aspect of the invention, the dosing system is in a free position that opens the chute so that a portion of the solid detergent can fall through the discharge opening and below the starting point of the chute so that a portion of the solid detergent cannot fall through the discharge opening. further comprising a blocking member arranged to be movable back and forth particularly in a translational manner between a blocking position blocking the chute in a blocking position located on the configured to check the chute area below the blocking point or/and the chute area above the blocking point.

The present invention additionally relates to a dishwashing container, a door mounted to the dishwashing container so as to be pivotable about a horizontal door pivot axis close to the floor to close a dishwashing chamber formed in the dishwashing container, and an input disposed on the door for solid detergent A household dishwasher comprising a system, the dosing system comprising a storage chamber for receiving a solid detergent supply and defining a falling section leading to an outlet opening for a portion of the detergent extracted from the solid detergent supply. The discharge opening allows a portion of the extracted detergent to enter the dish washing room. According to the invention, there is provided a protective cover associated with the outlet opening in space and movably arranged for selectively opening and blocking the outlet opening and an electrically controllable in particular electrically operated, actuatingly fastened to the protective cover for moving the protective cover. A household dishwasher comprising the dosing system comprising an actuator is provided.

DE 10 2014 115 512 A1 mentioned at the outset already discloses a protective cover for covering the discharge opening at the end of the drop section. The protective cover according to this patent document is constructed in a gravity pendulum manner and closes the discharge opening when the door is opened and turned horizontally. However, when the door is closed, the protective cover rotates under the influence of gravity to the open position with the exit open. The vent opening is thus open for the entire duration of the operating cycle of the dishwasher, so that the spray can pass through the vent opening into the falling section at any time during the operating cycle. In contrast, by changing from a purely passive protective cover that responds to gravity to an actively controllable protective cover, the protective cover can be closed even in the operating phase where water is sprayed into the dishwasher. This can protect the detergent stored in the storage compartment (magazine) to a high degree from damage by moisture ingress.

In some embodiments, the dosing system comprises a free position that opens the chute to allow a portion of the solid detergent to fall through the discharge opening and a block positioned below the starting point of the chute to prevent a portion of the solid detergent from falling through the discharge opening. It further comprises a blocking member arranged to be movable back and forth, particularly in a translational manner, between blocking positions for blocking the chute in position, said blocking member being actuatedly fastened to the actuator for movement of the blocking member. Accordingly, in these embodiments, the blocking member and the protective cover are fastened to the same actuator in a driving manner. This allows the blocking member and the protective cover to be actuated in a synchronized manner, and furthermore, the layout is simplified in terms of construction, which provides for only one actuator (and optionally one reduction gear) to actuate both components. because it becomes

In some embodiments, the actuator is in a closed position where, during a dishwasher's dishwashing program operation, the protective cover blocks the drain opening for most of the program run, but opens when a predetermined event occurs. In this regard, the predetermined event can be, for example, a dosing operation in which a detergent fraction is removed from the storage compartment and sent to the dropping section. As soon as the dispensed detergent portion is delivered to the dishwasher, the protective cover can be closed again. Overall, the time during which the protective cover frees the drain opening during the operating program of the dishwasher can be reduced to a very short period, for example a few seconds. Thereby, the ingress of moisture into the falling section and the storage chamber can be effectively prevented.

According to another aspect, the present invention provides a dishwashing container, a door mounted to the dishwashing container so as to be pivotable about a horizontal door pivot axis close to the floor to close a dishwashing chamber formed in the dishwashing container, and a door for solid detergent Provided is a household dishwasher having a dosing system disposed in the The dosing system includes a storage chamber that receives the solid detergent supplied and defines a falling section leading to an outlet opening for a portion of the detergent extracted from the solid detergent supply. According to this aspect, the discharge opening allows a portion of the extracted detergent to enter the dishwashing chamber, and when viewed along the door pivot axis, the discharge opening is arranged eccentrically with respect to the door transverse center. This is based on the assumption that, in at least some dishwashers, the water jet impacts approximately the center of the door (when viewed transversely to the door) during dish washing. By arranging the outlet openings offset with respect to the center, it is possible to reduce the possibility of undesired entry of spray into the dosing system through the outlet openings.

For example, when viewed along the door pivot axis, the opening center of the outlet opening is disposed offset with respect to the door lateral center by at least 4 cm or at least 8 cm or at least 12 cm.

In general, the goal is to be able to store as much detergent in the dosing system as possible so that the user can replenish the magazine of the dosing system relatively infrequently. This is also the case for configuring the magazine as an annular magazine. If square detergent tablets are placed in a magazine in an annular shape that lies on the large side (smaller side facing each other), the total number of detergents that can be accommodated is relatively small. On the other hand, the rotor of the annular magazine defines a plurality of tablet compartments distributed in the circumferential direction about the rotor axis, and is in the form of a flat body having opposing large faces and small faces connecting the large faces, and has a large face. When placing each of the detergent tablets that are longer than thick and wider and at the same time longer than the width (for example, in the case of a square) such that they stand within one of the tablet compartments on one of the smaller longitudinal sides, the annular magazine More detergent tablets can be stored in the In particular, the detergent tablets may be disposed into the tablet compartment in such a way that each is oriented substantially radially when viewed axially in the annular magazine. In this radial orientation, the detergent tablets have their large faces facing each other in the circumferential direction. However, it does not exclude arranging the detergent tablets in an orientation that is oblique to the radial direction with the annular magazine facing axially. In both cases, a relatively large number of detergent tablets can be stored by storing the detergent tablets erected on the small edges (as viewed in the axial direction) within the annular magazine.

The present invention also provides a tablet input system for installing a household dishwasher, comprising a magazine for receiving detergent tablets in two stacks arranged side by side, and an extractor for extracting detergent tablets from the stack and transferring the extracted detergent tablets to a chute to provide. The extractor has an extractor member arranged to be movable relative to the magazine to individually provide each stack for the purpose of extracting detergent tablets from the stack. According to the present invention, the extractor member is formed by a body of rotation to be rotatable about an axis of rotation, the two stacks being arranged side by side along a plane substantially orthogonal to the axis of rotation, the body having two extraction pockets, , the brew pockets are distributed particularly non-uniformly in the circumferential direction, each sized such that detergent tablets from the magazine can fall into the brew pocket in question.

For example, the two extraction pockets may lie within a circumferential segment of the body of rotation that extends no more than 220 degrees or no more than 200 degrees or no more than 180 degrees. The rotating body is arranged so that the side-by-side arrangement direction of the tablet stack is substantially parallel to the rotation plane of the rotating body, and the installation depth of the extractor in the direction of the rotation axis of the rotating body can be made relatively small. Thus, it is possible to take into account the usable installation space which is normally limited on the dishwasher door in the direction of the door thickness.

Alternatively or in addition to the configuration of the extractor element as a rotating body, such a tablet dosing system may comprise a blower for introducing blowing air into the magazine, the impeller of the blower being arranged between the two stacks.

The present invention further provides a magazine for order storage of detergent tablets, a chute for transferring the detergent tablets extracted from the magazine by gravity to an outlet opening, and a chute for opening the chute so that the extracted detergent tablets can fall through the outlet opening Provided is a tablet dosing system for installation in a domestic dishwasher comprising a blocking member disposed to be movable between a free position and a blocking position blocking the chute from falling through an outlet opening. The tablet dosing system features a blower for creating a flow of blowing air, the blower comprising an impeller seated in an impeller chamber, the impeller chamber extracting detergent tablets from the chute or/and magazine and dispensing the extracted detergent tablets A blow air supply is connected to an extractor chamber in which an extractor member movably disposed for delivery to the chute is received. Blowing air generated by the blower may be introduced into the chute or/and extractor chamber by a blowing air supply connection to prevent steam or/and spray from entering the magazine.

Finally, the present invention relates to a dishwashing container, a door mounted to the dishwashing container so as to be pivotable about a horizontal door pivot axis close to the floor to close a dishwashing chamber formed in the dishwashing container, and disposed on the door for solid detergent A household dish washing machine having an integrated dosing system, wherein the door has an inner lining on an inner side of the door facing the dish washing room when the door is closed. The dosing system includes a storage chamber for receiving a supply of solid detergent and a chute for conveying the portion of solid detergent removed from the supply of solid detergent to the outlet opening in a gravity driven manner. The dosing system further comprises a blower for introducing blowing air into the storage chamber or/and the chute, the blower comprising an impeller rotatably disposed within the impeller chamber. The impeller chamber is connected to a storage chamber or/and a chute with a supply of blowing air, the impeller chamber being formed by a housing component assembled to an inner lining on the rear side, the housing component being particularly internal for sucking air into the impeller chamber One or more suction slots open towards the lining.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

First refer to FIG. 1 . The dishwasher intended for home use shown in FIG. 1 is generally indicated by reference numeral 10 . The dishwasher includes a machine body (dishwashing container) 12 in which a dish washing chamber 14 is formed. The machine body 12 is equipped with a door 16 pivotable about a horizontal pivot shaft 17 close to the floor. The door 16 is in the fully open position shown in FIG. 1 (the door plane is positioned substantially horizontally) and the closed position in which the door closes the dishwashing chamber 14 to the outside and stands substantially vertically. can be rotated between One or more dish baskets and optionally cutlery trays for holding items of cutlery and cutlery to be washed may be inserted into dishwashing chamber 14 in a manner known per se. The control unit 18 indicated by a broken line serves to control the operation of the dishwasher 10 . In the example shown, the control unit 18 is housed in the door 16 . It will be appreciated that in other embodiments, at least a portion of the control unit 18 may be arranged on the machine body 12 .

The control unit 18 not only controls the dishwashing operation and optionally the drying operation of the dishwasher 10, but also a dosing system ( 20) to control it. In the further description, it is assumed that the solid detergent is formed in the form of tablets, ie detergent tablets produced in a given shape, for example approximately square. Accordingly, the dosing system 20 is also referred to as a tablet dosing system hereinafter.

In the example shown in FIG. 1 , the tablet dosing system 20 is arranged at the door 16 . The door 16 has an inner lining panel 22 arranged on the inner side of the door 16 facing the dishwasher 14 when the door 16 is closed, and is generally made of sheet metal material. At least a portion of the tablet dosing system 20 may fit externally to the inner lining panel 22 . Alternatively or additionally, at least a portion of the tablet dosing system 20 may be hidden behind the inner lining panel 22 . Alternatively or additionally, the inner lining panel 22 may include one or more apertures into which at least a portion of the tablet dosing system 20 may be inserted.

In different drawings, elements having the same or the same effect are provided with the same reference numbers, but different lowercase letters are appended to the reference numbers to distinguish different exemplary embodiments. Below, unless otherwise indicated, reference may be made to an element having the same number to an observation made with respect to the drawing in which the element in question is first described.

In the exemplary embodiment shown in FIG. 2 , the tablet dosing system 20a is in the form of a screw cover in the example shown but a cover 24a which may alternatively be in the form of, for example, a hinged or pivotable cover or a sliding cover. ) has Although not separately shown in FIG. 2 , at least a portion of the magazine of the tablet dosing system 20a in which detergent tablets may be stored may be located under the cover 24a. By opening the cover 24a, the user can access the tablet magazine. Access may in particular allow a user to refill the tablet magazine and/or remove the refillable magazine component via access.

The cover 24a may be designed to be transparent in at least one cover area so that a user can visually check the fill level of the tablet magazine without removing the cover 24a.

In the exemplary embodiment of FIG. 2 , the tablet dosing system 20a further has a hood 26a covering the discharge opening located at the bottom end of the chute (falling channel or falling section) not shown in more detail in FIG. 2 , This allows detergent tablets removed from the tablet magazine to fall into the dishwasher's dishwashing chamber. It can be seen in FIG. 2 that the hood 26a is arranged eccentrically offset relative to an imaginary centerline M running from the door upper edge to the door lower edge at the center of the door 16a. Here, the door center refers to a center viewed along the pivot axis 17a, that is, viewed in the transverse direction of the door 16a. In the example shown, the tablet dosing system 20a is arranged entirely on the other side of the transverse center of the door 16a. The eccentric offset of the hood 26a of the chute with respect to the door transverse center and the exhaust opening concealed below it can ensure that the spray hitting the door 16a in the door transverse center area cannot enter the chute through the exhaust opening. have. As long as the spray is highly expected to hit the door 16a in the door transverse central region, the probability of moisture entering the chute and tablet magazine may be reduced by the transverse offset arrangement of the tablet dosing system 20a. The magnitude of the transverse offset, denoted d in FIG. 2 , may be, for example, at least 10 cm or more, for example at most 15 cm or at most 20 cm, depending on the installation space in the door in the transverse direction of the door 16a. In FIG. 2 the distance d extends from the centerline M to the imaginary midpoint of the outlet opening of the chute located at or below the hood 26a.

In the exemplary embodiment of FIG. 2 , a cover cap 28a is further shown on the inside of the door 16a, below which various other additives necessary for the washing operation of the dishwasher, in particular liquid additives, for example rinse aids. More than one filling opening for the same additive may be located.

Reference is now made to the exemplary embodiment of FIGS. 3A and 3B . The tablet dosing system 20b shown in FIGS. 3A and 3B includes an annular magazine 30b having a magazine housing 32b and a rotor 36b rotatable about a rotor axis 34b. The rotor 36b is inserted into a magazine chamber 37b having a circular contour defined by the magazine housing 32b. A rotor drive unit (generally: a drive mechanism) for driving the rotor 36b which rotates about the rotor shaft 34b is associated with the annular magazine 30b. The rotor drive unit is not shown in detail in FIGS. 3A and 3B . The rotor drive unit may for example comprise an electric motor as a source of drive power. The rotor 36b may be removed for cleaning purposes, and with reference to FIG. 2 , it may be arranged hidden behind the cover 24a so that a user can directly access the rotor 36b by opening the cover 24a.

The rotor 36b defines a plurality of tablet compartments (typically: storage compartments) 38b distributed in an annular arrangement about the rotor axis 34b. The tablet compartment 38b may also be referred to as a storage cell, and for this reason the rotor 36b may also be referred to as a cell wheel or dispenser wheel. Adjacent purification compartments 38b are, in each case, separated from one another by a separating wall structure 40b. In a situation as shown in FIGS. 3A and 3B , detergent tablet 42b is disposed in a portion of tablet compartment 38b . In the example shown, the detergent tablet 42b has a generally rectangular shape in the form of a flat body with an opposing large side 44b and a small side 46b between the large side 44b. The rectangular shape of the detergent tablet 42b means that it has two long and small sides 46b extending in the longitudinal direction of the rectangle and two short and small sides 46b extending in the width direction of the rectangle. do. The length and width of the rectangular detergent tablet 42b is greater than the thickness of the detergent tablet 42b measured between the large sides 44b.

In the example of FIGS. 3A and 3B , the tablet compartment 38b is so narrow that the detergent tablets 42b must be placed in the annular magazine 30b one by one so that they stand on one of their smaller faces 46b. Standing on the small side means that the detergent tablet 42b has an axial bearing surface with the large side 44b facing each other in the circumferential direction, one of the small sides 46b being part of the rotor 36b in the example shown. 47b). Since the width of the tablet compartment 38b is small, the detergent tablet 42b cannot be placed on its large side. In the example shown, detergent tablets 42b are placed in tablet compartment 38b that rests on one of their smaller, longer sides 46b (ie, the smaller side in the longitudinal direction). In this way, the overall height of the annular magazine 30b can be kept small. The depth of the tablet compartment 38b, measured in the axial direction of the rotor 36b, is greater than the width of the detergent tablet 42b. The separating wall structure 40b thus projects axially over the detergent tablet 42b when the detergent tablet 42b is inserted into the tablet compartment 38b standing on the small longitudinal side. Detergent tablets 42b disposed in tablet compartment 38b are oriented substantially radially.

The illustrated manner of introducing detergent tablets 42b into the tablet compartment 38b allows a relatively large number of detergent tablets 42b to be accommodated in the annular magazine 30b. However, it is in principle seen to dimension the tablet compartment 38b wide enough in the circumferential direction of the faceted rotor 36b as shown for illustrative purposes in FIG. 4 so that detergent tablets 42b can be placed therein. It is not excluded within the scope of the disclosure. In this figure, only the rotor 36c with the tablet section 38c is shown. A detergent tablet 42c approximately rectangular in shape, as in the example shown in FIGS. 3A and 3B , is inserted into one of the tablet compartments 38c lying on the large side.

In the example shown in Fig. 4, the rotor 36c is designed in a disk rotor manner, and has a disk portion 48c from which a separating wall structure 40c projects axially on one side of the disk. it can be seen that The disc portion 48c forms an axial bearing surface for the detergent tablet 42c; Alternatively, the rotor 36c is not designed as a disk rotor, but is completely open axially in the region of the tablet compartment 38c so that the detergent tablet 42c lies axially on the chamber base of the magazine chamber 37c. You can think of designing.

The dividing wall structure 40c is arranged radially on the outside of the central cup portion 50c of the rotor 36c. The central cup portion 50c is bounded by a cup side 52c extending in the circumferential direction and a cup base 54c, the cup base 54c constituting a drive mechanism for rotationally driving the rotor 36c. Cupwise defines the space in which the element can be accommodated in a space-saving manner. This cup interior is accessible from the other axial side of the rotor 36c (ie, from the rear axial side away from the viewer of FIG. 4 ).

In the example shown in FIG. 4 , it can be seen that the cup side 52c axially overlaps with the dividing wall structure 40c as well as even protrudes axially above it. Thus, the mentioned component of the drive mechanism can be received in the dosing system in the approximately axial region of the detergent tablet 42c inserted into the tablet compartment 38c. This makes the overall height of the dosing system small.

Reference is now again made to FIGS. 3A and 3B . An annular magazine 30b with rotor 36b is arranged under a magazine cover (eg, cover 24a in FIG. 2 ) so that after removing the cover a user accesses rotor 36b and tablet compartment 38b. can do. The intended installation position of the annular magazine 30b is substantially parallel to the major plane of the dishwasher door (eg door 16a), ie the annular plane of the annular magazine 30b is substantially parallel to the door plane. should be placed When the door is closed, the rotor shaft 34b is accordingly oriented substantially horizontally. Thus, when the door is closed, gravity acts substantially along the annular plane of the annular magazine 30b.

Tablet compartment 38b is designed to open radially outward. When the rotor 36b is removed from the magazine chamber 37b, the detergent tablet 42b inserted into the tablet compartment 38b can easily slide radially outward from the rotor 36b. The rotor 36b itself does not include any structure to prevent the detergent tablet 42b inserted into the tablet compartment 38b from sliding radially outward. When the rotor 36b is inserted into the magazine chamber 37b, the rotor is surrounded by a chamber boundary wall 56b extending in a radially annular wall manner from the outside around the rotor 36b. The chamber partition wall 56b is part of the magazine housing 32b and radially delimits the magazine chamber 37b from the outside. In the example shown in FIGS. 3A and 3B , two openings are formed in the chamber partition wall 56b. The first of these openings, also referred to as the extraction opening, defines an input opening 58b located at the six o'clock position of the annular magazine 30b (when viewed from the front of the vertically standing door). the other opening forms a blowing air supply opening 60b; It is located in the example shown at the 12 o'clock position, but could alternatively be located in other angular positions of the magazine housing 32b, eg somewhere between the 9 o'clock position and the 3 o'clock position.

Via the dispensing opening 58b, the magazine chamber 37b extends substantially vertically downwards from the magazine chamber 37b (as viewed from the front, as viewed from the upright upright door) and the detergent tablet 42b is moved only by gravity. It is connected to a chute 62b that allows it to freely fall from the magazine chamber 37b to an outlet opening 64b located at the end of the chute 62b. The chute 62b is formed by a chute housing 66b fixedly connected to the magazine housing 32b; For example, the magazine housing 32b and the chute housing 66b may be formed by one-piece integrated housing components. At the outlet opening 64b, the chute 62b opens to the area surrounding the door on the inside of the door. When the door is closed, the detergent tablets 42b separated from the discharge opening 64b may flow into the dishwasher's dishwasher and be absorbed and dissolved by the dishwasher water sprayed or collected there. Referring to the exemplary embodiment of FIG. 2 , the exhaust opening 64b is located in the region of the hood 26a.

Associated with the chute 62b is a blocking slider 68b that is linearly adjustable between the blocking position shown in FIG. 3A and the unlocking position shown in FIG. 3B . To actuate the shut-off slider 68b, the tablet dosing system 20b is controlled by an actuator (not shown in more detail in FIGS. 3A and 3B ), for example a control unit, which is the control unit 18 of FIG. 1 . It may have an electric actuator. In the blocking position according to FIG. 3a , the blocking slider 68b blocks the fall of the detergent tablet 42b through the chute 32b; In the release position according to FIG. 3b , the shut-off slider 68b is moving far enough out of the chute 62b to allow the detergent tablet 42b to fall through the chute 62b. The purpose of the shutoff slider 68b is to prevent spray or/and hot steam from rising through the chute 62b towards the magazine chamber 37b. The shut-off slider 68b thus closes the chute 62b over substantially the entire chute cross-section in the shut-off position.

For the dosing (ie extraction) of detergent tablets 42b, the rotor 36b is positioned at the position where the tablet compartment 38b filled with detergent tablets 42b is at the 6 o'clock position, i.e. radially the dosing opening 58b moved to the opposite position. Dosing opening 58b is large enough to allow detergent tablets 42b stored in tablet compartment 38b in question to fall through dosing opening 58b into chute 62b. However, detergent tablets 42b may not immediately fall into the chute 62b despite the tablet compartment 38b in question being correctly oriented relative to the dosing opening 58b. For example, detergent tablet 42b may not rest completely loosely in tablet compartment 38b. In order to eliminate any obstacles that could prevent the detergent tablet 42b from immediately falling out of the tablet compartment 38b, a conceivable movement pattern for the rotor 36b is to pass the tablet compartment 38b in question through the dosing opening ( 58b) in a first direction (eg, clockwise) and partially moving past the input opening 58b in the same rotational direction. According to this movement pattern, the rotor 36b rotates in the opposite direction of rotation (eg counterclockwise) until the tablet compartment 38b in question is again in a position exactly opposite the dosing opening 58b in the radial direction. is moved back to If desired, this rearward movement of the rotor 36b may be continued slightly further such that the tablet compartment 38b in question also moves slightly in the opposite direction past the dosing opening 58b. Overall, the pattern of movement of the rotor 36b for emptying the tablet compartment 38b may include moving the rotor 36b back and forth within the area of the dosing opening 58b at least once. This reciprocating movement may remove any blockage that prevents the detergent tablet 42b positioned in the tablet compartment 38b from immediately falling off.

Upon emptying the tablet compartment 38b, the blocking slider 68b may assume a blocking position as shown in FIG. 3A . Detergent tablets 42b that have fallen out of the tablet compartment 38b are stopped from falling by the shut-off slider 68b and remain in front of the shut-off slider 68b until the shut-off slider 68b is moved to the release position according to FIG. 3B . . It is conceivable to discharge detergent tablets 42b from the annular magazine 30b into the chute 62b only after the operating program of the dishwasher has started. Alternatively, the detergent tablets 42b are ejected from the annular magazine 30b into the chute 62b even before the dishwasher's operating program has started, and the shut-off slider 68b is operated until the program is started and such ejection is actually required. It is conceivable to use the to keep the detergent tablet 42b ready. In order to deliver the detergent tablets 42b extracted from the annular magazine 30b into the dishwasher's dishwashing compartment, the shut-off slider 68b then simply has to be moved to the release position. For example, at the end of the operating cycle of the dishwasher's operating program, the detergent tablets 42b are ejected from the annular magazine 30b into the chute 62b, and the shut-off slider 68b until the next operating program of the dishwasher is started. ) to keep it ready by

An alternative dosing procedure provides that at the exact moment the detergent tablet 42b is ejected from the annular magazine 30b into the chute 62b the shut-off slider 68b is previously in the release position according to FIG. 3b . Then, detergent tablets 42b that have fallen into the chute 62b are not stopped by the shut-off slider 68b, but can freely and uninterruptedly fall through the entire chute 62b to the discharge opening 64b. The shut-off slider 68b does not open, for example, until just before the detergent tablet 42b is extracted from the annular magazine 30b, and the shut-off slider 68b closes again as soon as the detergent tablet 42b passes the chute 62b.

3a, 3b schematically show sensors 70b, 72b capable of monitoring the chute 62b. These sensors operate in conjunction with the fall of the detergent tablet 42b. For example, each of these sensors 70b and 72b operates in a light barrier fashion where the detergent tablet 42b is blocked for a short time as it falls through the test beam of that light barrier. 3a , 3b, the sensor 70b is arranged above the blocking point at which the blocking slider 68b can block the chute 62b; A sensor 72b is arranged below this blocking point. It will be appreciated that it may be sufficient to provide only one of the sensors 70b and 72b (either either the sensor 70b or the sensor 72b). This is particularly the case if the detergent tablet 42b extracted from the annular magazine should not be stopped in free fall by the shut-off slider 68b. Thus, when the dosing system 20b is operated such that the detergent tablets 42b extracted from the annular magazine 30b fall through the entire chute 62b in a sliding manner without interruption, one light in the area of the chute 62b It may be sufficient to provide a barrier (or generally a single sensor). However, if the operation of the dosing system 20b is configured such that detergent tablets 42b falling on the chute 62b are first stopped by the shutoff slider 68b (corresponding to the example of FIG. 3a ), both above and below the shutoff slider 68b . It may be convenient to provide a sensor to A sensor located above the blocking point, in this example shown, the sensor 70b is positioned advantageously to detect the presence of the detergent tablet 42b when the detergent tablet 42b rests against the closed blocking slider 68b. .

The blowing air supply opening 60b connects the magazine chamber 37b to the impeller chamber 74b in which the impeller 76b of the blower, generally designated 78b, is seated. the impeller chamber 74b is formed by a blower housing 80b fixedly connected to the magazine housing 32b; For example, the blower housing 80b and the magazine housing 32b are integrally formed. The blower 78b serves to create a flow of blowing air into the magazine chamber 37b. From the magazine chamber 37b, the introduced blowing air passes into the chute 62b through the inlet 58b. Blowing air acts against entry of hot steam into chute 62b through outlet opening 64b and can cause a drying action when moisture enters dosing system 20b.

The blower 78b includes a drive unit for driving the rotating impeller wheel 76b. These are not shown in detail in Figures 3a and 3b. Likewise, a control unit not shown, for example the control unit 18 of FIG. 1 , serves to control the operation of the blower 78b. This control unit controls the blower 78b in such a way that blowing air is generated when the shut-off slider 68b is in the unlocked position according to FIG. 3b at least during the dishwashing phase of the dishwasher. During at least a part of the operating phase of the dishwasher in which the shut-off slider 68b is in the shut-off position according to FIG. 3A , it may be advantageous to drive the blower 78b to further generate blowing air. This allows hot steam to enter the magazine chamber 37b through the chute 62b even when the shutoff slider 68b is closed and/or a cover disposed over the annular magazine 30b (eg, cover 24a in FIG. 2 ). ))) because it cannot always be completely excluded. The blocking slider 68b may not completely seal the chute 62b in the blocking position. Likewise, the seal between the magazine housing 32b and a magazine cover, such as the cover 24a of FIG. 2 seated thereon, may not be complete. Therefore, it should generally be expected that the presence of airtight defects could be that hot steam or/and spray could penetrate the interior regions of the dosing system 20b and compromise the quality of the stored detergent tablets 42b. Therefore, it may be advantageous to drive the blower 78b even when the shut-off slider 68b is closed. For example, it is conceivable that the blower 78b is operated substantially uninterrupted during the entire stage of the operation program of the dishwasher in which dish washing water is sprayed into the dish washing room of the dishwasher.

Reference will now be made to the exemplary embodiment of FIGS. 5A-5C . This is not substantially different from the exemplary embodiment of FIGS. 3A and 3B . In FIGS. 5A-5C it can be seen a slider housing 82d forming a slide channel for a linearly movably arranged blocking slider (eg blocking slider 68b in FIGS. 3A, 3B ), whereby The chute 62d may be selectively blocked and released at a location spaced a predetermined distance below the input opening 58d. The slider housing 82d may be integrally connected to the chute housing 66d.

In Figure 5a it is further visible a cover 24d pivotally attached to the chute housing 66d, through which the annular magazine 30d can be closed. By opening the cover 24d, the user can access the magazine chamber 37d and the rotor 36d inserted therein. In particular, when the cover 24d is open, the rotor 36d can be detached from the magazine chamber 37d and the annular magazine 30d, for example after removing a set screw (not shown) accessible by opening. This is possible. The rotor 36d can thus be fixedly but releasably installed in the annular magazine 30d in such a way that it cannot be removed alone by hand, particularly without an auxiliary tool (eg, a screwdriver).

The components of drive mechanism 84d that serve to rotationally drive rotor 36d are further shown in FIG. 5B . The drive mechanism 84d uses, for example, an electric motor (not shown in detail) as a drive power source, and includes a gear train 86d having a reduction function for transmitting the drive force of the power source to the rotor 36d. do. In the example shown, the gear train 86d is arranged in a central cup portion 50d concealed below the cup base 54d and has teeth formed on the inner peripheral side of the cup side 52d (not shown in more detail in FIG. 5B ). and a drive pinion 88d that engages with the . With the appropriate dimensions of the cup portion 50d, the entire gear train 86d together with the mentioned electric motor can be accommodated inside the cup delimited by the central cup portion 50d. The force-transmitting engagement of the cup side 52d and the drive pinion 88d around the inner circumference reduces the overall height of the annular magazine 30d.

When the cover 24d is opened, the user can access all tablet compartments 38d of the annular magazine 30d. Accordingly, the user can fill each of the tablet compartments 38d with detergent tablets 42d without rotating the rotor 36d when the cover 24d is open. To this end, the rotor 36d may remain in the magazine chamber 37d; The rotor 36d does not need to be removed from the magazine chamber 37d. Therefore, it is possible to fill the detergent tablet 42d into the rotor 36d in a state in which the rotor 36d is force-transmitted to the driving mechanism 84d.

The exemplary embodiment of FIGS. 6A and 6B, in the form of a rotatable cover in the example shown, is placed on a chute housing 66e to be rotatable between the open position shown in FIG. 6A and the closed position shown in FIG. 6B. It is substantially different from the exemplary embodiment of FIGS. 5A to 5C in that a protective cover 90e held on the . In the open position according to FIG. 6A , the protective cover 90e releases the discharge opening 64e, so that the discharge opening 64e is released for discharge of the detergent tablet 42e. In the closed position according to FIG. 6b , the protective cover 90e is pivoted over the discharge opening 64e so that the discharge opening 64e is blocked against falling of the detergent tablet 42e. The protective cover 90e is such that when in the closed position according to FIG. 6B hot steam or spray enters the chute (not shown in more detail in FIGS. 6A, 6B ) formed inside the chute housing 66e at the outlet opening 64e. to prevent

In this regard, the dosing system 20e of FIGS. 6a and 6b is equipped with a double barrier to prevent the rise of vapors and/or sprays through the chute and into the area of the annular magazine 30e. the first barrier is formed by the protective cover 90e; The second barrier, indicated only by dashed lines in Figures 6a, 6b, is on a blocking slider 68e that is movably guided within the slider housing 82e and capable of blocking the chute in a blocking position between the top and bottom of the chute end. is formed by

Also shown is a schematically indicated actuator 92e in FIG. 6a . It is connected through the shut-off slider 68e and the mechanical drive connection 94e, and is connected through the protective cover 90e and the mechanical drive connection 96e. The drive connections 94e, 96e comprise, for example, one or more gears, and the actuator 92e is, for example, in the form of an electric actuator. The protective cover 90e and the blocking slider 68e can be supplied with driving power from a single, ie, common source, through the driving connections 94e and 96e. In particular, the actuator 92e is controlled and the drive connections 94e, 96e are configured such that the shut-off slider 68e and the protective cover 90e open and close in a synchronized manner when the actuator 92e is actuated. Thus, when the blocking slider 68e is moved from the unlocking position according to FIG. 6a to the blocking position according to FIG. 6b , the protective cover 90e is simultaneously pivoted from the open position according to FIG. 6a to the closed position according to FIG. 6b . The opposite is also true. The actuator 92e is controlled by a suitable control unit, for example the control unit 18 of FIG. 1 .

Reference is now made to the exemplary embodiment of FIGS. 7A-7D . 7A is a perspective view of the annular magazine 30f as seen when the user opens the magazine cover (eg, cover 24a in FIG. 2 or cover 24d in FIG. 5A ). FIG. 7B is a view similar to FIG. 7A , but with the cup base 54f of the central cup portion 50f of the rotor 36f removed so that the interior of the central cup portion 50f is visible. 7C shows a cross-section through the annular magazine 30f, and FIG. 7D is a partial cutaway overall view of the tablet dosing system 20f equipped with the annular magazine 30f of FIGS. 7A-7C , wherein the tablet being emptied. Next to compartment 38f is the test position.

It will be appreciated that in the exemplary embodiment of FIGS. 7A-7D , a window opening 98f is formed in the cup side 52f of the rotor 36f in the region of each of the tablet compartments 38f. An annular magazine 30f fixedly disposed relative to the magazine housing 32f is accommodated within the cup of the central cup portion 50f and implements, for example, a light barrier or a portion thereof, in one of the tablet compartments 38f of detergent tablets. It further comprises a photoelectric sensor component 100f ( FIG. 7D ) that serves to detect the presence or absence. The sensor component 100f is arranged to be able to ascertain the tablet compartment 38f to be emptied next for the presence or absence of detergent tablets at the test position offset at an angle to the dosing position. As a result, the test position is angularly offset with respect to the 6 o'clock position. In the example shown in Figure 7d, the test positions correspond to approximately five and one quarter positions. Since the test position corresponds to an angular position in which the tablet compartment 38f in question is not yet located completely opposite the input opening 58f, the detergent tablets present in the tablet compartment 38f in question at the test position are not yet located in the tablet compartment 38f. ) to the chute 62f. In the illustrated example, the test position corresponds to an angular position at which the tablet compartment 38f is located substantially outside the extent of the input opening 58f. At the same time, the test position is located close enough to allow the tablet compartment 38f in question to move to a neighboring dosing position when the rotor 36f is rotated (ie, no tablet compartment 38f has been previously placed in the dosing position). should not be reached).

In this way, it is possible to check by means of the sensor component 100f whether there are detergent tablets in the tablet compartment 38f in question before the tablet compartment 38f is moved to a position radially opposite the dosing opening 58f. do. If the magazine controller (eg, formed by the control unit 18 of FIG. 1 ) determines that the tablet compartment 38f in question is empty, it emits, for example, a visual and/or audible indication, through which the user may be requested to fill the annular magazine 30f with new detergent tablets. Of course, other predefined control actions are conceivable as well. Moreover, the magazine controller can check whether or not the tablet compartment 38f is actually empty when one of the tablet compartments 38f is moved to a position radially opposite the dosing opening 58f. To this end, the magazine controller causes the rearward movement of the rotor 36f to the rotational position where the corresponding tablet compartment 38f is back in the test position, so that the sensor component 100f can check the tablet compartment 38f again in question. can If the magazine controller determines that the tablet compartment 38f in question is empty, it knows that the detergent tablets previously placed therein have actually emptied properly into the chute 62f.

Window opening 98f in cup side 52f of rotor 36f allows sensor component 100f to “see” metaphorically into tablet compartment 38f. To this end, the sensor component 100f may comprise, for example, a light-emitting diode which transmits a sensor light beam 101f ( FIG. 7d ) oriented radially or at a relatively small angle to the radial direction. The sensor light beam 101f passes through the window opening 98f of the tablet compartment 38f in question (when in the test position) and, if present in the tablet compartment 38f, either collides with the detergent tablet or the entire tablet. It is formed radially outward toward the chamber boundary wall 56f passing through. According to some embodiments, a photodetector (eg, a photodiode or phototransistor), not shown in greater detail, may be seated on the chamber confinement wall 56f at a location substantially radially opposite the sensor component 100f. can According to another embodiment, such a light detector may be included in the sensor component 100f, where the light barrier operates by a reflective principle and detects whether the sensor light beam 101f impinges upon the detergent tablet or chamber boundary wall 56f. Depending on whether or not different degrees of reflection are used.

The two exemplary embodiments of FIGS. 8 and 9 are capable of imparting a pulse-like propulsive force in a falling direction (ie in the direction of gravity) to a detergent tablet at the dosing position (ie radially opposite the dosing opening) within the tablet compartment. It differs from the previous exemplary embodiments in that it has a pusher. This push can help the detergent tablets fall into the chute from the tablet compartment in question, for example when agglomeration prevents the detergent tablets from falling out of the tablet compartment independently.

In the exemplary embodiment of FIG. 8 , the pusher referred to is in the form of a spring-loaded pusher 102g that produces the desired push from its intrinsic spring tension. In the example shown, the spring-loaded pusher 102g is formed by a spring bow 104g that defines an elastically deflectable pusher nose 106g. The spring bow 104g may be formed by a metal strip bent into a desired shape by bending. When one of the tablet compartments 38g is in the dosing position (i.e., at the entrance toward the chute at a position radially opposite from the dosing opening), the pusher nose 106g is positioned on the cup side 52g of the rotor 26g. It projects to some extent into the tablet compartment 38g in question through a window opening 107g formed in the . Each tablet section 38g of the rotor 36g is designed to have such a window opening 107g. 7A-7D , the window opening 98f therein may serve as the window opening 107g of FIG. 8 . As the rotor 36g rotates, the opening edge of the corresponding window opening 107g pushes the pusher nose 106g radially inward and cups until the neighboring window opening 107g moves into the area of the pusher nose 106g. The side 52g may slide past the pusher nose 106g. The pusher nose 106g then snaps into the window opening 107g due to its inherent spring tension and pushes against the detergent tablet positioned in the associated tablet compartment 38g. Thus, detergent tablets are actively pushed into the chute.

In the exemplary embodiment of FIG. 9 , an electromagnetic pusher 108h is provided instead of a spring-loaded pusher. The electromagnetic pusher has an electromagnetic actuator 110h and a pusher head 112h that can be advanced in a pulsed manner by excitation of the electromagnetic actuator 110h. The pusher head 112h has the same function as the pusher nose 106g of the spring-loaded pusher 102g of FIG. 8; Upon excitation of the electromagnetic actuator 110h, the pusher head 112h moves to some extent into the tablet compartment 38h through the window opening 98h of the tablet compartment 38h at the current dosing position, ie at a position radially opposite to the chute. Move. If there are detergent tablets inside the tablet compartment 38h and the detergent tablets have not yet fallen into the chute by themselves, the pusher head 112h pushes the detergent tablets so that the detergent tablets fall into the chute.

10 is a partial cut-away view of an exemplary embodiment of blower 78i, with impeller 76i housed in blower housing 80i. It can be seen that the blower housing 80i is mounted on the rear side of the door lining panel 22i of the door 16i (the rear side is the side of the door lining panel 22i facing the inside of the door, that is, the side away from the dishwasher) means). The intake of air by the impeller 76i takes place through an intake slot 114i formed in the blower housing 80i and opened toward the inner lining panel 22i. By fitting the blower housing 80i to the inner lining panel 22i, the intake slot 114i is thus closed at the end. These suction slots 114i may be provided along all four sides of the blower housing 80i having a rectangular outline in the illustrated example. Since the intake slot 114i is close to the panel, intake of air occurs close to the inner lining panel 22i. Air flows substantially along inner lining panel 22i through intake slot 114i into impeller chamber 74i and is pushed by impeller 76i into the magazine chamber of the annular magazine and adjacent portions of the input system.

In the exemplary embodiment of FIG. 11 , tablet dosing system 20k includes a stacked magazine 116k with two magazine chutes 118k rather than an annular magazine. Each magazine chute allows a plurality of detergent tablets 42k, which in the illustrated example to be rectangular in shape, to be stored in the tablet stack. The two magazine chutes 118k extend over a portion of the length of the chute at least at a distance from each other, and the gap between the two magazine chutes 118k is to accommodate the blower 78k, more precisely the impeller 76k. used to house the blower housing 80k of the receiving blower 78k. Accordingly, blowing air can be uniformly supplied to both of the two magazine chutes 118k by the blower 78k. Blowing air is blown directly by blower 78k into the chute chamber of magazine chute 118k.

In order to provide the two tablet stacks separately, ie to individually remove detergent tablets 42k from a selected tablet stack, the tablet dosing system 20k is configured to remove the detergent tablets 42k from one of the entire stacks (corresponding to the illustration of FIG. 11 ). Extractor slider 120k linearly adjustable by a slider drive unit not shown in detail, for example a motorized slider drive, between different positions that receive detergent tablets 42k and are ready to deliver the received detergent tablets 42k to the chute. ) is included. In FIG. 11 only the chute housing 66k can be seen. Further details on the construction and function of the extractor slider 120k are described in DE 10 2019 009 054 A1, in particular in the description relating to the embodiment of FIGS. 7 to 10 . The content of the referenced DE specification is hereby incorporated by reference in its entirety.

Figure 11 shows additional blowers 78'k, 78"k arranged at different positions of the input system 20k and the blower 78k and showing alternative or additional placement positions of these blowers. Blower 78' k) is directly connected to the chute inside the chute housing 66k to supply blowing air, and the blower 78"k is directly connected to the slider chamber in which the extractor slider 120k is slidably accommodated. It should be understood that not all three blowers 78k, 78'k, 78"k have to be provided. One of the three blowers mentioned is to blow air through the magazine chute 118k, the chute and the slider chamber. If sufficient, the remaining blowers may be omitted.

In the exemplary embodiment of FIG. 12 , the tablet dosing system 201 includes a stack magazine 116l with two magazine chutes 118l provided by a common extractor member as in the exemplary embodiment of FIG. 11 . . 12, this extractor member is in the form of a rotary extractor 122l housed in an extractor housing 126l so as to be rotatable about an axis of rotation 124l. In a situation where tablet dosing system 201 is installed, axis of rotation 124l is substantially perpendicular to the major plane of the dishwasher door; The two magazine chutes 118l are thus fitted into the door such that the tablet stack formed in the magazine chute 118l by detergent tablets 42l is arranged side by side along a plane orthogonal to the axis of rotation 124l.

The rotary extractor 122l has two extraction pockets 128l each dimensioned to receive a detergent tablet 42l. As can be readily seen in FIG. 12 , the two extraction pockets 128l are non-uniformly distributed in the circumferential direction of the rotary extractor 122l. In other words, they are not opposite to each other. Instead, two extraction pockets 128l are formed in the example shown within the 180° segment of the rotary extractor 122l. During operation, the rotary extractor 122l provides, for example, one of the tablet stacks having one of the extraction pockets 128l (i.e. extracts detergent tablets 42l from the tablet stack), and then the rotary extractor 1221 122l) is rotated slightly further forward or backward to rotate the received detergent tablet 42l into a position where it can fall from the corresponding brew pocket 128l into the chute 62l, the other of the two brew pockets 128l being the other tablet. Going down the stack, it can be controlled so that detergent tablets can fall from that other tablet stack into the rotary extractor 122l. By repeatedly changing the direction of rotation of the rotary extractor 122l, each tablet stack can be provided alternately, wherein the extraction pockets 128l are each always used for the same tablet stack.
