Description

Dosing solid detergent into a household dishwasher {DOSING OF A SOLID DETERGENT IN A DOMESTIC DISHWASHING MACHINE}

The present disclosure generally relates to the dosing of solid detergents into domestic dishwashers.

In personal home dishwashers, technological development is progressing toward providing dishwashers with magazines that can store larger amounts of solid detergent. In the case of liquid rinse aids, there are already solutions for storing enough liquid to use in multiple dishwasher cycles. For actual detergents, which are often in the form of compressed detergent tablets or pourable detergent powders, storage solutions with automatic dosing are also increasingly being explored.

Regarding the prior art regarding solutions for 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 easy for users to handle. When a user must insert detergent powder into the magazine of the powder input unit, the user may easily spill some of the detergent powder. In general, if you use detergent tablets, you do not need to be afraid of this inconvenience. However, especially in the case of detergent tablets that are not spherical, oval or disc shaped, in order to ensure that the dishwasher can reliably remove a generally defined quantity of detergent tablets (usually one tablet per operating cycle) during operation, the magazine It is necessary to store detergent tablets in an organized manner. Magazines for organized storage of detergent tablets can form, for example, one or more stacking chutes in which one detergent tablet can be stored stacked on top of another (see for example DE 10 2019 009 054 A1 ).

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

The object of the present invention is to provide a dosing system intended for use in dishwashers, suitable for dishwashers, and distinguished by a simple structure and simple operating principle.

In order to achieve the above object, the present invention provides a household dishwasher, wherein the dishwasher has a dishwashing container, rotatable about a horizontal door pivot axis close to the floor to close the dishwashing chamber formed in the dishwashing container. It includes a door mounted on a dishwashing container, and a dispensing system for solid detergent disposed on the door. The insertion system includes a rotor disposed in a magazine chamber so as to be rotatable about the rotor axis, the rotor being distributed in a circumferential direction about the rotor axis and defining a plurality of storage compartments that are open radially outward; An input opening in the border wall of the magazine chamber, through which each storage compartment can be individually and continuously moved by rotation of the rotor to a position radially opposite to the input opening in order to empty the storage compartment in question, and a chute connected to the magazine chamber through an input opening. The rotor is arranged so that the rotor's plane of rotation is substantially parallel to the main plane of the door, and when the door is closed and one of the storage compartments is moved to a position radially opposite to the loading opening, a portion of the solid detergent stored in the storage compartment is moved. An inlet opening is arranged below the rotor so that the material can fall from the storage compartment into the chute through the inlet opening solely by gravity.

According to this solution, it is sufficient to rotate the rotor to a position where one of the storage compartments is in a position radially opposite to the filling opening. At this dosing position of the storage compartment, the portion of solid detergent located therein can fall radially out of the storage compartment and fall through the dosing opening into the chute solely by the force of gravity. The storage compartment does not need to be rinsed with a spray of water, nor does it need to use an additional pusher to push part of the solid detergent out of the storage compartment to the side (horizontally). The input opening can be formed, for example, in the 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 the rotor's plane of rotation 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 state of a closed door. Typically, the door is mounted on the dishwashing bin of a dishwasher so that it can pivot about a horizontal pivot axis close to the floor. Therefore, a closed door is oriented vertically, and to open the door, the door must be pivoted horizontally. Therefore, in order to transfer the detergent from the storage compartment to the chute by gravity, the chute must be arranged below the rotor with the orientation towards the pivot axis close to the floor. By stepwise further rotation of the rotor, detergent portions can be continuously transferred from the respective storage containers into the chute.

Solid detergents may be in pourable powder or tablet form. These detergent tablets are typically made by compressing one or more powdered starting materials (in some cases containing various active substance compositions) into a predetermined spatial shape. It is common to find detergent tablets that are roughly square in shape and have a roughly rectangular outline when viewed from the larger side, with a length and width greater when viewed from the larger side than the thickness when viewed from the smaller side. However, the present invention is of course not limited to these square detergent tablets; The use of other types of detergent tablets is likewise contemplated within the scope of the present disclosure. If a part of a solid detergent is mentioned here, that part consists of a predetermined number of such detergent tablets, for example a single detergent tablet. In the case of powdered detergents, the portion consists of the amount of powder introduced into the storage compartment in question. This amount can be measured specifically, especially when the magazine has been filled with detergent by the manufacturer, or it can be measured visually, for example when introduced manually by the consumer for the first fill or refill.

In some embodiments, the chute defines a falling section that extends particularly substantially linearly downwardly from the input opening to the discharge opening to allow a portion of the solid detergent to freely fall within the chute, the chute extending from the door at the discharge opening into the dishwashing compartment. It is open. In this embodiment, a portion of the solid detergent removed from the magazine can fall through the input opening and through the entire chute to the discharge opening and out of the discharge opening solely under the influence of gravity without additional auxiliary devices. After exiting the discharge opening, a portion of the solid detergent may be absorbed and dissolved by the dishwashing water sprayed or collected in the dishwashing compartment.

In some embodiments, the chute is arranged immovably with respect to the entry opening. For example, an injection system includes a common housing component that defines at least a portion of a chute simultaneously with at least a portion of a magazine chamber.

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

Changing the rotation direction of the rotor can be used for various purposes. For example, detergent tablets can easily become stuck or remain in the storage compartment, so that they do not immediately fall out of the storage compartment once the storage compartment is moved to a position opposite the loading opening with the first access stroke. Moving the storage compartment one or more times over the loading opening may also help in such cases to keep the cleaning tablets away from the storage compartment. Accordingly, in some embodiments, the control unit is configured to control the drive mechanism such that one of the storage compartments moves back and forth at least once in order to empty it. In particular, the storage compartment in question can be moved at least partially past the input opening at least once and then moved again to a position radially opposite to 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 is actually emptied. Accordingly, in some embodiments, the dosing system is provided comprising a sensor system that causes 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 (dosing position) relative to the dosing opening. Here, the control unit is configured to control the drive mechanism so that one of the storage compartments is moved to the empty position and then the storage compartment is moved back within the detection range of the sensor system. When the storage compartment is moved back, a sensor system can determine whether any part of the solid detergent remains in the storage compartment. Otherwise, it is certain that the storage compartment has been properly emptied if the storage compartment is identified as full before it is moved to the emptying position. 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 driving the rotor to rotate, a control unit for controlling the drive mechanism, and a sensor system coupled to the control unit, capable of detecting whether a portion of solid detergent is present in the storage compartment. If the control unit detects that a part of the solid detergent remains in one of the storage compartments after the storage compartment has been moved to the emptying position at least once relative to the filling opening, the control unit controls the drive mechanism to empty the other one of the storage compartments. Move to location. Therefore, even if one of the storage compartments cannot be successfully emptied (for example, if the cleaning tablets stick in that storage compartment due to the action of moisture and do not fall off), the functionality of the dosing system is maintained. If a storage compartment cannot be emptied after a predefined number of emptying attempts, the dosing system attempts to empty the next storage compartment. Therefore, there is no need to stop running the dishwashing program.

If the control unit detects that the storage compartment cannot be emptied despite 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 any accumulated amounts of detergent.

Hot steam and/or spray from the dishwashing room can enter the chute and/or magazine chamber. Hot steam or spray can be harmful to detergent stored in the annular magazine. For example, detergents may partially dissolve and form clumps or stick to the walls of the storage compartment. The influx of hot moisture can be counteracted by a 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 generating a stream of blowing air into the magazine chamber and/or into the chute.

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

The suit can be selectively blocked and disarmed. For this purpose, the dosing system is arranged to be movable in particular in a translational manner between a blocking position, which blocks the chute so that part of the solid detergent does not fall into the discharge opening, and a release position, which releases the chute so that part of the solid detergent falls into the discharge opening. It may include a blocking member. 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 (i.e. when the blocking member is in the blocking position), undesirable ingress of vapor or/and spray into parts 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 loading reaches the end of the chute, and from there into the dishwashing compartment of the dishwasher. With the chute open, it is recommended to run the blower to direct hot steam and/or spray as far away from the magazine as possible. Accordingly, an embodiment of the invention provides a control unit for a blower, the control unit being configured to control the blower to produce blowing air at least during the phase when the blocking member is in the released position.

Of course, since the blocking member is in the blocking position, it is also possible to control the blower to generate additional blower while the chute is closed. This is because it cannot be ruled out that vapors and/or sprays may enter the magazine chamber due to a defective seal. Therefore, it may be convenient to operate the blower even when the chute is blocked. For example, in some embodiments, it may be contemplated to run the blower substantially continuously during the entire wetting phase of the dishwasher's operating program, and further, if desired, during a subsequent drying phase in which the dishes are actively dried by the dishwasher. You 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 direction of fall. The pusher may be in the form of a spring-actuated pusher or an electromagnetically actuated pusher, for example.

In some embodiments, the injection system includes an electrically controllable drive mechanism for rotationally driving the rotor and, in particular, the pivotably 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, and once the magazine cover is removed, the respective storage compartments can be accessed to fill a portion of solid detergent.

The rotor may be secured against axial removal from the magazine chamber by one or more fastening members (e.g. screws), and an auxiliary tool is required to release it.

According to a further aspect, the present invention is a dosing system for a domestic dishwasher, the dosing system comprising a rotor disposed or capable of being placed in a magazine chamber so as to be rotatable about the rotor axis, the rotor being connected by a cup side and a cup base. defining a central cup portion, and circumferentially distributed radially outside the central cup portion, arranged to axially overlap the sides of the cup, forming a plurality of storage compartments each containing a portion of solid detergent; Rotor, an electrically controllable drive mechanism for driving the rotor in rotation, in which the electromechanical or/and mechanical components of the drive mechanism, in particular the electric motor or/and the reduction gear, are accommodated inside the cup, in the ready state of operation of the dosing system, so that they A dosing system for a domestic dishwasher is provided that includes a drive mechanism at least partially hidden beneath a base. Accommodating the components of the drive mechanism in the central cup portion is advantageous in reducing the overall height of the injection system. In particular, the inner circumference of the cup side can be used to provide teeth in engagement with the drive pinion of the drive mechanism arranged in the central cup portion.

Another aspect of the present invention is a dosing system for a household dishwasher, the dosing system comprising a rotor disposed or capable of being placed in a magazine chamber so as to rotate about the rotor axis, the rotor being rotated in a circumferential direction around the rotor axis. a rotor distributed over a rotor forming a plurality of storage compartments, each containing a portion of solid detergent; a photoelectric sensor system capable of detecting the presence of a portion of solid detergent within the storage compartment, the sensor system being configured to A dosing system for a domestic dishwasher is provided that includes an opto-electric sensor system configured to direct a sensor light beam directed radially outwards or from radially outwards in a direction. Illuminating a light beam directed radially inward or through a storage compartment at a relatively small angle (acute angle) to the radial direction allows the light-emitting and/or light-receiving components to radially enter the storage compartment within the axial height range of the storage compartment. Allows them to be arranged directionally inward or/and radially outward. Therefore, the sensor system does not require additional installation space in the vertical direction. This is advantageous considering the constraints on the installation space that the door of a household dishwasher generally imposes in the direction of the door thickness.

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

Another aspect of the invention is a dishwashing container, a door mounted on the dishwashing container pivotable about a horizontal door pivot axis close to the floor to close a dishwashing compartment formed in the dishwashing container, and a door mounted on the door for solid detergent. A domestic dishwasher having a disposed dosing system is provided. The input system includes a magazine for storing solid detergent, a chute for transporting a portion of the solid detergent removed from the magazine to the discharge opening by gravity, and opening the chute to allow a portion of the solid detergent to fall through the discharge opening. a blocking member arranged to move back and forth, especially in a translational manner, between a free position and a blocking position that blocks the chute from a blocking position positioned below the starting point of the chute so that no part of the solid detergent can fall through the discharge opening; an electrically controllable actuator for driving, and while the dishwashing program of the dishwasher is running, the blocking member is in the blocking position for most of the period of the program, but when removing a portion of the solid detergent from the magazine the removed portion is in the chute. and a control unit configured to control the actuator to allow the chute to fall freely within the chute from its starting point 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 delivered from the magazine into the chute is not temporarily stopped by the blocking member because the blocking member is still in the blocking position. Instead, the control unit ensures that the blocking member is in the released position when the detergent portion removed from the magazine falls into the chute. Therefore, the detergent portion can fall through the entire chute at once. For this purpose, the control unit is suitably programmed or configured to transfer the blocking member from the blocking position to the releasing position at an appropriate time before the portion of detergent delivered from the magazine to the chute reaches the point where the blocking member is located. As soon as the detergent portion passes the blocking member, the blocking member can immediately move back to the blocking position.

Another aspect of the invention is a dishwashing container, a door mounted on the dishwashing container pivotable about a horizontal door pivot axis close to the floor to close a dishwashing compartment formed in the dishwashing container, and a door mounted on the door for solid detergent. A domestic dishwasher having a disposed dosing system is provided. The input system includes a magazine for storing solid detergent, a chute for transporting a portion of the solid detergent removed from the magazine to the discharge opening by gravity, and opening the chute to allow a portion of the solid detergent to fall through the discharge opening. a blocking member arranged to move in particular in a translational manner back and forth between a free position and a blocking position that blocks the chute so that a portion of the solid detergent cannot fall through the discharge 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, in response to the received operator's predetermined operating command, without starting the dishwashing program of the dishwasher. This function of the control unit allows the blocking member to be moved to the released position for cleaning purposes, allowing the user to reach all areas of the chute with a cleaning tool, for example a brush or toothbrush.

According to another aspect of the invention, there is provided a dosing system for a domestic dishwasher, the dosing system comprising: a magazine for storing solid detergent, a chute for conveying by gravity a portion of the solid detergent removed from the magazine to the discharge opening; Between a free position, which opens the chute to allow part of the solid detergent to fall through the discharge opening, and a blocking position, which blocks the chute at a blocking position located below the starting point of the chute, so that no part of the solid detergent can fall through the discharge opening. a blocking member arranged to move in particular in a translational manner back and forth, a sensor system associated with the chute, in particular a photoelectric sensor system, said sensor system 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 chute to be scanned using sensors to detect the dropping of detergent portions removed from the magazine or the presence of detergent portions resting in a (blocking) blocking member. Accordingly, the functional reliability of the input system can be increased. The sensor system makes it possible to determine whether portions of the detergent actually entered and/or passed through the chute during the dosing operation. For example, a sensor system can 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 shining into the chute.

Another aspect of the present invention is a dosing system for a household dishwasher, the dosing system comprising a rotor disposed or capable of being placed in a magazine chamber so as to rotate about the rotor axis, the rotor being rotated in a circumferential direction around the rotor axis. a rotor distributed and forming a plurality of storage compartments, each containing a portion of the solid detergent, a chute for transporting 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 device. 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 this, a sensor system capable of detecting the presence of a portion of solid detergent in a chute. In this aspect of the invention, the sensor system is configured to both scan at least one of the storage compartments for the presence of a detergent portion and monitor the chute for entry or passage of a detergent portion.

In the last-mentioned aspect of the invention, the dosing system has a free position that opens the chute to allow a portion of the solid detergent to fall through the discharge opening and a position below the starting point of the chute such that no portion of the solid detergent can 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 at It is configured to check the chute area below the blocking point and/or the chute area above the blocking point.

Additionally, the present invention provides a dishwashing container, a door mounted on the dishwashing container capable of pivoting about a horizontal door pivot axis close to the floor to close a dishwashing compartment formed in the dishwashing container, and an input disposed in the door for solid detergent. A domestic dishwasher with a system, the dosing system comprising a storage chamber containing a supply of solid detergent and defining a drop section leading to a discharge opening for a portion of the detergent extracted from the solid detergent supply. The discharge opening allows some of the extracted detergent to enter the dishwashing compartment. According to the invention, a protective cover associated with the discharge opening in space and movably arranged for selectively opening and blocking the discharge opening and an electrically controllable, especially motorized, drive fastened to the protective cover for moving the protective cover. A domestic dishwasher is provided that includes the above dosing system including an actuator.

DE 10 2014 115 512 A1 mentioned at the beginning already discloses a protective cover for covering the discharge opening at the end of the falling 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 directed horizontally. However, when the door is closed, the protective cover rotates under the influence of gravity to the open position, leaving the exit door open. The discharge opening is therefore open during the entire period of the operating cycle of the dishwasher, so that the spray can pass through the discharge opening into the dropping 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 during the operating phase when water is sprayed into the dishwashing compartment. This provides a high level of protection for detergents stored in the storage compartment (magazine) from damage due to moisture ingress.

In some embodiments, the dosing system has a free position that opens the chute to allow a portion of the solid detergent to fall through the discharge opening and a blocking position located below the starting point of the chute to prevent the portion of the solid detergent from falling through the discharge opening. It further comprises a blocking member arranged to be movable in a particularly translational manner back and forth between blocking positions blocking the chute in position, said blocking member being drivenly engaged with an 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 driven manner. This allows the blocking element and the protective cover to operate in a synchronized manner and also simplifies the outline in terms of construction, as only one actuator (and optionally one reduction gear) is provided to actuate both components. Because it becomes.

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

According to another aspect, the present invention provides a dishwashing container, a door mounted on the dishwashing container pivotable about a horizontal door pivot axis close to the floor to close a dishwashing compartment formed in the dishwashing container, and a door for solid detergent. Provided is a household dishwasher having a dosing system arranged in. The dosing system includes a storage chamber that receives the supplied solid detergent and defines a drop section leading to a discharge opening for a portion of the detergent extracted from the solid detergent supply. According to this aspect, the discharge opening allows part of the extracted detergent to enter the dishwashing compartment, and when viewed along the door pivot axis, the discharge opening is arranged eccentrically with respect to the door transverse centre. This is based on the assumption that, in at least some dishwashers, the water jet strikes approximately the center of the door (center when viewed across the door) during dishwashing. By locating the discharge opening offset from the center, the possibility of unwanted entry of spray into the dosing system through the discharge opening is reduced.

For example, when viewed along the door pivot axis, the opening center of the discharge opening is arranged offset by at least 4 cm or at least 8 cm or at least 12 cm with respect to the door transverse centre.

In general, the goal is to be able to store as much detergent as possible in the dosing system so that the user has to refill the dosing system's magazine relatively infrequently. This is also the case when the magazine is configured as an annular magazine. If square detergent tablets are placed in a ring shape with the large side facing each other (small sides facing each other), the total number of detergents that can be stored is relatively small. On the other hand, the rotor of an annular magazine defines a plurality of tablet compartments distributed circumferentially about the rotor axis, and has a flat body shape with opposing large faces and small faces connecting the large faces, and the large face is visible. When each detergent tablet, which is longer and wider than it is thick and at the same time longer than it is wide (e.g. square), is placed inside one of the tablet compartments so that it stands on one of the longitudinal small sides, the annular magazine Allows you to store more detergent tablets. In particular, the detergent tablets may be disposed within the tablet compartment in such a way that each is substantially radially oriented when viewed axially in the annular magazine. With this radial orientation, the detergent tablets have their large faces facing each other in the circumferential direction. However, it is not excluded to arrange the detergent tablets in an orientation oblique to the radial direction while looking axially at the annular magazine. In both cases, storing the detergent tablets propped up on a small edge (when viewed axially) within an annular magazine makes it possible to store a relatively large number of detergent tablets.

The present invention also provides a tablet loading system for installation in a household dishwasher, including a magazine for storing 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 extractor members arranged to be movable relative to the magazine to individually serve each stack for the purpose of extracting detergent tablets from the stack. According to the present invention, the extractor member is formed by a rotating body rotatable about a rotating axis, the two stacks are arranged side by side along a plane substantially orthogonal to the rotating axis, and the rotating body has two extraction pockets. , the extraction pockets are distributed particularly unevenly in the circumferential direction, each of a size such that detergent tablets can fall from the magazine into the corresponding extraction pocket.

For example, the two extraction pockets may lie within a circumferential segment of the rotary body extending less than 220 degrees or less than 200 degrees or less 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 rotating axis of the rotating body can be made relatively small. Therefore, it is possible to take into account the generally limited available installation space 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, this tablet dosing system may comprise a blower for introducing blowing air into the magazine, the impeller of which is arranged between the two stacks.

The invention further provides a magazine for ordered storage of detergent tablets, a chute for gravity transporting detergent tablets extracted from the magazine to a discharge opening, and opening the chute to allow the extracted detergent tablets to fall through the discharge opening. A tablet dosing system for installation in a domestic dishwasher is provided, including a blocking member disposed movable between a free position and a blocking position that blocks the chute to prevent detergent tablets from falling through the discharge opening. The tablet dosing system features a blower for generating a flow of blowing air, the blower comprising an impeller seated in an impeller chamber, the impeller chamber extracting detergent tablets from a chute or/and magazine and dispensing the extracted detergent tablets. A supply of blowing air is connected to the extractor chamber, which houses an extractor member movably disposed for delivery to the chute. The blowing air generated by the blower can be introduced into the chute or/and the extractor chamber by the blowing air supply connection to prevent vapor or/and spray from entering the magazine.

Finally, the present invention provides 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 solid detergent disposed in the door. A domestic dishwasher with a built-in loading system, wherein the door has an inner lining on the inner side of the door which faces a dishwashing compartment when the door is closed. The dosing system includes a storage chamber for receiving a solid detergent supply, and a chute for transporting the solid detergent portion removed from the solid detergent supply to the discharge opening in a gravity driven manner. The introduction system further comprises a blower for introducing blown air into the storage chamber and/or chute, the blower comprising an impeller rotatably disposed within the impeller chamber. The impeller chamber is connected with a storage chamber or/and a chute and a blowing air supply, the impeller chamber being formed by a housing component assembled to an inner lining on the rear side, the housing component having an inner lining in particular for sucking air into the impeller chamber. It has one or more suction slots open towards the lining.

The present invention will be described below with reference to the attached drawings.

First, refer to Figure 1. The dishwasher intended for domestic use shown in Figure 1 is generally designated at 10. The dishwasher includes a machine body (dishwashing container) 12 with a dishwashing chamber 14 formed therein. The machine body 12 is equipped with a door 16 that can pivot about a horizontal pivot axis 17 close to the floor. The door 16 has a fully open position shown in FIG. 1 (the door plane is positioned substantially horizontally) and a closed position in which the door closes the dishwashing compartment 14 to the outside and stands substantially vertically. can be rotated between. One or more dish baskets and optionally a cutlery tray for holding items of cutlery and cutlery to be washed may be inserted into the dishwashing compartment 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 built into 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 removes a portion of the solid detergent supplied in an automatic manner and delivers it to the dishwashing compartment 14. 20) plays a role in controlling. In the further description, it is assumed that the solid detergent is formed in the form of a tablet, i.e. a detergent tablet produced in a predetermined shape, for example approximately square. Therefore, the dosing system 20 is hereinafter also referred to as a tablet dosing system.

In the example shown in FIG. 1 , the tablet dispensing system 20 is arranged in the door 16 . The door 16 has an inner lining panel 22 arranged on the inner side of the door 16 facing the dishwashing compartment 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 be externally fitted 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 loading system 20 may be inserted.

In the different drawings, elements that are the same or have the same effect are given the same reference numerals, with different lowercase letters appended to the reference numerals to distinguish different exemplary embodiments. Unless otherwise indicated below, reference may be made in relation to the same numbered element to observations made in relation 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 provided with a cover 24a which in the example shown is in the form of a screw cover, but could alternatively be in the form of a hinged or pivotable cover or a sliding cover, for example. ) has. Although not separately shown in FIG. 2 , at least a portion of the magazine of the tablet loading system 20a in which detergent tablets can be stored may be located under the cover 24a. By opening the cover 24a, the user can access the tablet magazine. The access may in particular allow a user to refill a tablet magazine and/or remove a refillable magazine component via the access.

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

In the exemplary embodiment of Fig. 2, the tablet dosing system 20a additionally has a hood 26a covering the discharge opening located at the bottom end of the chute (drop channel or drop section), which is not shown in more detail in Fig. 2, This allows detergent tablets removed from the tablet magazine to fall into the dishwashing compartment of the dishwasher. In Figure 2, it can be seen that the hood 26a is arranged eccentrically offset from the center of the door 16a with respect to an imaginary center line M running from the upper edge of the door to the lower edge of the door. Here, the door center means the center when viewed along the pivot axis 17a, that is, the center when 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 and the discharge opening concealed beneath it with respect to the door transverse center can ensure that spray hitting the door (16a) in the door transverse center area cannot enter the chute through the discharge opening. there is. As the spray is largely expected to hit the door 16a in the door transverse central region, the probability of moisture entering the chute and tablet magazine can be reduced by a transversely offset arrangement of the tablet loading system 20a. The size of the transverse offset indicated by 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 Figure 2 the distance d extends from the center line M to the imaginary midpoint of the discharge opening of the chute located at or below the hood 26a.

In the exemplary embodiment of FIG. 2 , on the inside of the door 16a a cover cap 28a is further shown, underneath which various other additives required for the cleaning operation of the dishwasher, especially liquid additives, for example rinse aids, are shown. 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 dispensing 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 with a circular outline formed by the magazine housing 32b. A rotor drive unit (generally: a drive mechanism) for driving the rotor 36b rotating about the rotor axis 34b is linked to 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 include an electric motor as a source of drive power. The rotor 36b can be removed for cleaning purposes or, with reference to Figure 2, can be arranged hidden behind the cover 24a so that the user can directly access the rotor 36b by opening the cover 24a.

The rotor 36b defines a plurality of tablet compartments (generally: storage compartments) 38b distributed in an annular arrangement about the rotor axis 34b. The purification 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 distributor wheel. Adjacent tablet compartments 38b are, in each case, separated from each other by a separating wall structure 40b. In the situation shown in FIGS. 3A and 3B, the detergent tablet 42b is disposed in a portion of the tablet compartment 38b. In the example shown, the detergent tablet 42b has an approximately square shape in the form of a flat body with opposing large faces 44b and a small face 46b between the large faces 44b. The fact that the detergent tablet 42b has a square shape means that it has two long, small sides 46b extending in the longitudinal direction of the square and two short, small sides 46b extending in the width direction of the square. do. The length and width of the square detergent tablet 42b are greater than the thickness of the detergent tablet 42b measured between the large sides 44b.

In the example of Figures 3A and 3B, the tablet compartment 38b is so narrow that the detergent tablets 42b have to be placed one by one in the annular magazine 30b standing on one of their small sides 46b. Standing on the small side means that the detergent tablet 42b has its large sides 44b facing each other circumferentially, and one of the small sides 46b is an axial bearing surface, which in the example shown is part of the rotor 36b. It means that it lies in 47b). Since the width of the tablet compartment 38b is small, the detergent tablet 42b cannot be placed lying on its large side. In the example shown, detergent tablets 42b are placed in the tablet compartment 38b lying on one of their longer small sides 46b (i.e., the longitudinal small side). 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 protrudes axially above the detergent tablet 42b when the detergent tablet 42b is inserted into the tablet compartment 38b standing on its longitudinal side. Detergent tablets 42b disposed in tablet compartment 38b are substantially radially oriented.

The manner of introducing the detergent tablets 42b into the tablet compartment 38b shown allows a relatively large number of detergent tablets 42b to be accommodated in the annular magazine 30b. However, it is in principle desirable to dimension the tablet compartment 38b sufficiently wide in the circumferential direction of the faceted rotor 36b, as shown for illustrative purposes in Figure 4, to allow the detergent tablets 42b to be placed therein. are not excluded within the scope of disclosure. In this figure, only the rotor 36c with the purification compartment 38c is shown. As in the example shown in Figures 3a and 3b, a detergent tablet 42c, approximately square in shape, is inserted into one of the tablet compartments 38c lying on the large side.

In the example shown in Figure 4, the rotor 36c is designed in a disk rotor manner and has a disk portion 48c from which a separation wall structure 40c protrudes axially on one side of the disk. You can see 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 axially fully open in the area of the tablet compartment 38c so that the detergent tablets 42c lie axially on the chamber base of the magazine chamber 37c. You can think about designing.

The separating wall structure 40c is arranged radially outside 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, and the cup base 54c constitutes a drive mechanism for rotationally driving the rotor 36c. The cup method limits the space where elements can be accommodated in a space-saving manner. The interior of this cup is accessible from the other axial side of rotor 36c (ie, from the rear axial side away from the viewer in Figure 4).

In the example shown in Figure 4, it can be seen that the cup side 52c not only axially overlaps the separating wall structure 40c but even protrudes axially above it. The mentioned components of the drive mechanism can thus be received in the dosing system in the approximately axial region of the detergent tablet 42c inserted into the tablet compartment 38c. This reduces the overall height of the injection system.

Now refer again to Figures 3A and 3B. The annular magazine 30b with the rotor 36b is arranged under the magazine cover (e.g. cover 24a in Figure 2) so that the user has access to the rotor 36b and the tablet compartment 38b after removing the cover. can do. The intended installation position of the annular magazine 30b is substantially parallel to the main plane of the dishwasher door (e.g. door 16a), i.e. the annular plane of the annular magazine 30b is substantially parallel to the door plane. must be placed When the door is closed, the rotor axis 34b is thus oriented substantially horizontally. Therefore, when the door is closed, gravity acts substantially along the annular plane of the annular magazine 30b.

The tablet compartment 38b is designed to open radially outward. When the rotor 36b is removed from the magazine chamber 37b, the detergent tablets 42b inserted into the tablet compartment 38b can easily slide radially outward on 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 which extends in a radially annular wall fashion on the outside around the rotor 36b. The chamber partition wall 56b is part of the magazine housing 32b and radially partitions the magazine chamber 37b from the outside. In the example shown in FIGS. 3A and 3B, two openings are formed in the chamber compartment wall 56b. The first of these openings is also called the extraction opening and forms the input opening 58b located at the 6 o'clock position of the annular magazine 30b (when looking straight at the door standing vertically). The other opening forms a blowing air supply opening 60b; This is located in the example shown at the 12 o'clock position but could alternatively be located at other angular positions in the magazine housing 32b, for example somewhere between the 9 o'clock position and the 3 o'clock position.

Through the loading opening 58b, the magazine chamber 37b extends substantially vertically downwards from the magazine chamber 37b (viewed from the front with the door standing vertically) and the detergent tablets 42b are deposited solely by gravity. It is connected to the chute 62b allowing it to fall freely from the magazine chamber 37b into the discharge 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, magazine housing 32b and chute housing 66b may be formed by piecewise integrated housing components. At discharge opening 64b, chute 62b opens on the inside of the door to the area surrounding the door. When the door is closed, the detergent tablets 42b that fall from the discharge opening 64b may flow into the dishwashing compartment of the dishwasher and be sprayed there or absorbed and dissolved by the collected dishwasher water. Referring to the exemplary embodiment of Figure 2, discharge opening 64b is located in the area of 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 unlocked position shown in FIG. 3B. To drive the cut-off slider 68b, the tablet dosing system 20b is controlled by an actuator (not shown in more detail in FIGS. 3a, 3b), for example a control unit, control unit 18 in FIG. It may have an electric actuator. In the blocking position according to Figure 3a, the blocking slider 68b blocks the falling of the detergent tablets 42b through the chute 32b; In the released position according to Figure 3b, the blocking slider 68b has moved far enough out of the chute 62b to allow the detergent tablets 42b to fall through the chute 62b. The purpose of the blocking slider 68b is to prevent spray or/and hot vapor from rising through the chute 62b towards the magazine chamber 37b. The blocking slider 68b thus closes the chute 62b substantially over the entire chute cross-section in the blocking position.

For loading (i.e. extraction) of the detergent tablets 42b, the rotor 36b is positioned at the 6 o'clock position with the tablet compartment 38b filled with the detergent tablets 42b, i.e. in the radial direction through the loading opening 58b. Moved to the opposite location. The dosing opening 58b is large enough to allow the detergent tablets 42b stored in the tablet compartment 38b in question to fall through the dosing opening 58b into the chute 62b. However, the detergent tablets 42b may not immediately fall into the chute 62b even though the tablet compartment 38b in question is correctly oriented with respect to the loading opening 58b. For example, the detergent tablet 42b may not be completely loose in the tablet compartment 38b. In order to remove any obstructions that may prevent the detergent tablets 42b from immediately falling out of the tablet compartment 38b, the conceivable movement pattern for the rotor 36b is such that the tablet compartment 38b in question is positioned at the loading opening ( moving in a first direction (e.g., clockwise) toward 58b) and partially moving past the introduction opening 58b in the same rotational direction. According to this pattern of movement, the rotor 36b is rotated in the opposite direction (e.g. counterclockwise) until the tablet section 38b in question is again in a position exactly opposite to the radial direction of the dosing opening 58b. is moved back to If necessary, this rearward movement of the rotor 36b can be continued slightly further so that the tablet section 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. By this reciprocating movement, any blockages that prevent the detergent tablets 42b located in the tablet compartment 38b from falling immediately can be removed.

When emptying the purification compartment 38b, the blocking slider 68b can assume the blocking position as shown in Figure 3A. Detergent tablets 42b that have fallen out of the tablet compartment 38b are stopped from falling by the blocking slider 68b and remain in front of the blocking slider 68b until the blocking slider 68b moves to the release position according to FIG. 3B. . It is conceivable to discharge the 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 can be discharged from the annular magazine 30b into the chute 62b even before the dishwasher's operating program has started, and the blocking slider 68b can be operated until the program has started and their discharge is actually required. It is conceivable to keep the detergent tablet 42b in a ready state using . In order to deliver the detergent tablets 42b extracted from the annular magazine 30b into the dishwashing chamber of the dishwasher, the blocking slider 68b must then simply be moved to the released position. For example, at the end of the operating cycle of the dishwasher's operating program, the detergent tablets 42b are discharged from the annular magazine 30b into the chute 62b and the blocking slider 68b is held until the next operating program of the dishwasher is started. ) can be considered to be maintained in a prepared state.

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

3A, 3B schematically show sensors 70b, 72b capable of monitoring the chute 62b. These sensors operate in conjunction with the dropping of the detergent tablet 42b. For example, these sensors 70b and 72b each operate as a light barrier that is blocked for a short period of time when a detergent tablet 42b falls through the test beam of that light barrier. In the example shown in FIGS. 3A, 3B, the sensor 70b is arranged above the blocking point where the blocking slider 68b can block the chute 62b; 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, 72b (either sensor 70b or sensor 72b). This is especially the case if the detergent tablets 42b extracted from the annular magazine must not be stopped in free fall by the blocking slider 68b. Therefore, when the dosing system 20b is operated so that the detergent tablets 42b extracted from the annular magazine 30b fall through the entire chute 62b in an uninterrupted sliding manner, a single light is present in the area of the chute 62b. Providing a barrier (or usually a single sensor) may be sufficient. However, if the operation of the dosing system 20b is arranged so that the detergent tablets 42b that fall into the chute 62b are first stopped by the blocking slider 68b (corresponding to the example in Figure 3a), both above and below the blocking slider 68b. It may be convenient to provide a sensor for . The sensor positioned above the blocking point, in this example shown sensor 70b, is positioned advantageously to detect the presence of detergent tablet 42b when it 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 indicated as 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 formed as one piece. The blower 78b serves to generate 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. The blowing air may act against the entry of hot vapor into the chute 62b through the discharge opening 64b and cause a drying effect if moisture enters the dosing system 20b.

The blower 78b includes a drive unit to drive 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 in FIG. 1, serves to control the driving of the blower 78b. This control unit controls the blower 78b in such a way that blowing air is generated at least during the dishwashing phase of the dishwasher when the shut-off slider 68b is in the released position according to FIG. 3B. During at least part of the operating phase of the dishwasher when the blocking slider 68b is in the blocking position according to FIG. 3A , it may be advantageous to drive the blower 78b to generate additional blowing air. This means that even when the blocking slider 68b is closed, hot vapor flows into the magazine chamber 37b through the chute 62b and/or a cover placed over the annular magazine 30b (e.g., cover 24a in FIG. 2 ). This is because flowing past )) cannot always be completely excluded. Blocking slider 68b may not completely seal chute 62b in the blocking position. Likewise, the seal between the magazine housing 32b and a magazine cover, for example cover 24a of Figure 2, seated thereon may not be complete. Therefore, it should generally be expected that hot steam or/and spray may penetrate the internal area of the dosing system 20b and the presence of an airtightness defect could damage the quality of the stored detergent tablets 42b. Therefore, it may be advantageous to drive the blower 78b even when the blocking slider 68b is closed. For example, it is conceivable that the blower 78b is operated substantially uninterrupted during the entire operation program of the dishwasher in which dishwashing water is sprayed into the dishwashing compartment of the dishwasher.

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

In FIG. 5A, a cover 24d can be additionally seen, which is pivotably 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, it is accessible so that the rotor 36d can be separated from the magazine chamber 37d and the annular magazine 30d, for example after removing the fixing 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 particular in such a way that it cannot be removed alone by hand without an auxiliary tool (eg a screwdriver).

Components of the drive mechanism 84d that serve to rotate the 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 with a deceleration function for transmitting the driving force of the power source to the rotor 36d. do. In the example shown, the gear train 86d is arranged in the central cup portion 50d concealed beneath the cup base 54d and has teeth formed on the inner peripheral side of the cup side 52d (not shown in more detail in Figure 5b). It includes a drive pinion (88d) engaged with. With appropriate dimensions of the cup portion 50d, the entire gear train 86d together with the mentioned electric motor can be accommodated inside the cup bounded by the central cup portion 50d. The force transmission engagement of the cup side 52d and the drive pinion 88d at the inner circumference reduces the overall height of the annular magazine 30d.

When cover 24d is open, the user has access to all tablet compartments 38d of 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. For this purpose, 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 rotor 36d with the detergent tablets 42d while the rotor 36d is coupled to the drive mechanism 84d and force transmission.

6A and 6B, in the form of a rotatable cover in the example shown, on the chute housing 66e so that it can rotate between the open position shown in FIG. 6A and the closed position shown in FIG. 6B. It differs substantially from the exemplary embodiment of FIGS. 5A to 5C in that it is additionally provided with a protective cover 90e held on. In the open position according to Figure 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 detergent tablets 42e. The protective cover 90e, when in the closed position according to Figure 6b, prevents hot steam or spray from entering the discharge opening 64e into the chute formed inside the chute housing 66e (not shown in more detail in Figures 6a, 6b). prevent it from happening.

In this connection, the dosing system 20e of FIGS. 6a and 6b is equipped with a double barrier to prevent the rise of vapor and/or spray through the chute into the area of the annular magazine 30e. The first barrier is formed by the protective cover 90e; The second barrier is indicated only by a dashed line in FIGS. 6a, 6b and is attached to a blocking slider 68e that is movably guided within the slider housing 82e and is capable of blocking the chute at a blocking position between the upper and lower ends of the chute. is formed by

Also shown in Figure 6a is an actuator 92e, schematically indicated. It is connected to the blocking slider 68e via a mechanical drive connection 94e and to the protective cover 90e via a 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. Through the drive connections 94e and 96e, the protective cover 90e and the blocking slider 68e can be supplied with driving power from a single, ie common source. In particular, the actuator 92e is controlled and the drive connections 94e, 96e are configured so that the blocking slider 68e and the protective cover 90e open and close in a synchronized manner when the actuator 92e is actuated. Accordingly, when the blocking slider 68e is moved from the unlocked position according to Fig. 6a to the blocked 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. Actuator 92e is controlled by a suitable control unit, for example control unit 18 of FIG. 1 .

Reference is now made to the exemplary embodiment of FIGS. 7A-7D. FIG. 7A is a perspective view of the annular magazine 30f seen when the user opens the magazine cover (eg, cover 24a in FIG. 2 or cover 24d in FIG. 5A). Figure 7b is a view similar to Figure 7a, but with the cup base 54f of the central cup portion 50f of the rotor 36f removed, allowing the interior of the central cup portion 50f to be seen. FIG. 7C shows a cross-section through the annular magazine 30f, and FIG. 7D is a partial cutaway view of the tablet dispensing system 20f equipped with the annular magazine 30f of FIGS. 7A-7C, wherein tablets are emptied. Compartment 38f is next in the test location.

It will be seen that in the exemplary embodiment of FIGS. 7A-7D, window openings 98f are formed in the cup side 52f of the rotor 36f in each area of the tablet compartment 38f. An annular magazine 30f, fixedly arranged relative to the magazine housing 32f, is received inside the cup of the central cup portion 50f and, for example, embodying a light barrier or part thereof, is used to store detergent tablets in one of the tablet compartments 38f. It further includes a photoelectric sensor component 100f (FIG. 7D) that serves to detect presence or absence. The sensor component 100f is arranged to check the next to be emptied tablet compartment 38f for the presence or absence of detergent tablets at a test position offset at an angle with respect 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 position corresponds approximately to the 5 and 1/4 position. The test position corresponds to an angular position where the tablet compartment 38f in question is not yet positioned completely opposite the loading opening 58f, so that the detergent tablets present in that tablet compartment 38f at the test position are not yet positioned in the tablet compartment 38f. ) cannot fall into the chute (62f). In the example shown, the test position corresponds to an angular position where the tablet compartment 38f in question is located substantially outside the range of the dosing opening 58f. At the same time, the test positions are located close enough to allow the tablet compartment 38f in question to move to a neighboring dosing position when the rotor 36f rotates (i.e., any tablet compartment 38f must be placed in the dosing position in advance). should not be reached).

In this way, it is possible to check whether there are detergent tablets in the tablet compartment 38f in question by means of the sensor component 100f before the tablet compartment 38f is moved to a position radially opposite the loading opening 58f. do. If the magazine controller (e.g. formed by control unit 18 in Figure 1) determines that the tablet compartment 38f in question is empty, it emits, for example, a visual or/and audible indication, thereby alerting the user. You can ask the person to fill the annular magazine (30f) with new detergent tablets. Of course, other predefined control actions can be thought of as well. Moreover, the magazine controller can determine whether one of the tablet compartments 38f is actually empty if one of the tablet compartments 38f is moved to a position radially opposite the loading opening 58f. To this end, the magazine controller will cause the rotor 36f to move backwards to a rotational position where the tablet compartment 38f is again in the test position, allowing the sensor component 100f to re-identify the tablet compartment 38f. You can. Once the magazine controller determines that the tablet compartment 38f in question is empty, it knows that the detergent tablets previously placed therein have actually been properly emptied into chute 62f.

A window opening 98f in the cup side 52f of the rotor 36f allows the sensor component 100f to figuratively “see” into the tablet compartment 38f. For this purpose, the sensor component 100f may for example comprise a light-emitting diode transmitting a sensor light beam 101f (FIG. 7d) oriented radially or at a relatively small angle with respect 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 a detergent tablet is present in the tablet compartment 38f, collides with the detergent tablet or the entire tablet. It passes through and is formed radially outward toward the chamber boundary wall 56f. According to some embodiments, a photodetector (e.g., a photodiode or phototransistor), not shown in more detail, may be seated on the chamber defining wall 56f at a position substantially radially opposite to the sensor component 100f. You can. According to another embodiment, such a light detector may be included in the sensor component 100f, where the light barrier operates by the principle of reflection and determines whether the sensor light beam 101f impacts the detergent tablet or the chamber boundary wall 56f. Different degrees of reflection are used depending on the presence or absence of light.

The two exemplary embodiments of FIGS. 8 and 9 are capable of imparting a pulse-shaped propulsion force in the falling direction (i.e. in the direction of gravity) to detergent tablets at a dosing position (i.e. radially opposite the dosing opening) within the tablet compartment. It is distinguished from the previous exemplary embodiments in that there is a pusher. This push can help detergent tablets fall out of the tablet compartment in question into the chute, for example if agglomeration prevents the detergent tablet from falling out of the tablet compartment independently.

In the exemplary embodiment of Figure 8, the pusher referred to is in the form of a spring-loaded pusher 102g, which generates the desired push from the inherent spring tension. In the example shown, the spring-loaded pusher 102g is formed by a spring bow 104g that forms a resiliently 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., with the inlet facing the chute in a position radially opposite from the dosing opening), the pusher nose 106g is positioned against the cup side 52g of the rotor 26g. It protrudes to some extent into the tablet compartment 38g in question through the window opening 107g formed in . Each of the purification sections 38g of the rotor 36g is designed to have such window openings 107g. Looking at the example embodiment of FIGS. 7A-7D , window opening 98f therein may serve as 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, causing the cup to cup until the neighboring window opening 107g moves within the area of the pusher nose 106g. The side (52g) can 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 located in the associated tablet compartment 38g. The detergent tablets are thus actively pushed into the chute.

In the exemplary embodiment of Figure 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 Figure 8; Upon excitation of the electromagnetic actuator 110h, the pusher head 112h is pushed some way into the tablet compartment 38h through the window opening 98h of the tablet compartment 38h at the current loading position, i.e. at a position radially opposite to the chute. move If there is a detergent tablet inside the tablet compartment 38h and the detergent tablet has not yet fallen into the chute by itself, the pusher head 112h pushes the detergent tablet so that the detergent tablet falls into the chute.

10 is a partial cutaway view of an exemplary embodiment of a blower 78i, with an impeller 76i housed in a blower housing 80i. It will be seen that the blower housing 80i is mounted on the rear of the door lining panel 22i of the door 16i (the rear is the side of the door lining panel 22i facing the inside of the door, i.e. the side facing away from the dishwashing compartment. means). Suction of air by the impeller 76i occurs through a suction slot 114i formed in the blower housing 80i and open toward the inner lining panel 22i. By fitting the blower housing 80i to the inner lining panel 22i, the intake slot 114i is thereby closed at the end. These suction slots 114i may be provided along all four sides of the blower housing 80i, which in the example shown has a square outline. Because the intake slot 114i is close to the panel, intake of air occurs close to the inner lining panel 22i. Air flows substantially along the inner lining panel 22i through the intake slot 114i into the impeller chamber 74i and is pushed by the impeller 76i into the magazine chamber of the annular magazine and adjacent parts of the insertion system.

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

In order to separately feed two tablet stacks, i.e. to individually remove detergent tablets 42k from a selected tablet stack, the tablet loading system 20k is operated from one of the entire stacks (corresponding to the illustration in FIG. 11 ). an extractor slider (120k) linearly adjustable by a slider drive unit, for example an electric slider drive unit, not shown in detail, among other positions ready to receive detergent tablets (42k) and deliver the received detergent tablets (42k) to a chute; ) includes. In Figure 11 only the chute housing 66k is visible. Further details on the construction and function of the extractor slider 120k are described in DE 10 2019 009 054 A1, especially in the description relating to the embodiment of FIGS. 7 to 10 . The contents of the referenced DE specifications are incorporated herein by reference in their entirety.

Figure 11 shows additional blowers 78'k, 78"k arranged in different positions of the input system 20k and blower 78k and shows alternative or additional placement positions of these blowers. Blower 78' k) is directly connected to the blowing air supply to the chute inside the chute housing (66k), and the blower (78"k) is directly connected to the blowing air supply 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) must be provided, as one of the three mentioned blowers blows air through the magazine chute (118k), chute and slider chamber. If sufficient, the remaining blowers can be omitted.

In the exemplary embodiment of FIG. 12 , the tablet loading system 20l includes a stack magazine 116l having two magazine chutes 118l provided by a common extractor member as in the exemplary embodiment of FIG. 11 . For the exemplary embodiment of FIG. 12 , this extractor member is in the form of a rotary extractor 122l that is housed in an extractor housing 126l rotatable about a rotation axis 124l. In the situation where the tablet dosing system 20l is installed, the rotation axis 124l is substantially perpendicular to the main plane of the dishwasher door; Accordingly, the two magazine chutes 118l are fitted into the door so that the tablet stacks formed in the magazine chutes 118l by the detergent tablets 42l are arranged side by side along a plane perpendicular to the rotation axis 124l.

The rotary extractor 122l has two extraction pockets 128l each dimensioned to receive a detergent tablet 42l. As can be easily seen in Figure 12, the two extraction pockets 128l are distributed unevenly in the circumferential direction of the rotary extractor 122l. In other words, they are not diametrically opposed to each other. Instead, two extraction pockets 128l are formed in the example shown within a 180° segment of the rotary extractor 122l. During operation, rotary extractor 122l provides, for example, one of the tablet stacks with one of the extraction pockets 128l (i.e. extracts detergent tablets 42l from said tablet stack) and then rotary extractor ( 122l) is rotated slightly further forward or backward to a position where the received detergent tablets 42l can fall out of the extraction pocket 128l into the chute 62l, the other of the two extraction pockets 128l allowing the other tablets to fall. Going down the stack, detergent tablets can be controlled to fall from the other tablet stacks into the rotary extractor 122l. By repeatedly changing the direction of rotation of the rotary extractor 122l, each tablet stack can be provided alternately, where extraction pockets 128l are each always used for the same tablet stack.
