Technical Field

The invention relates to a domestic dishwasher, a method for operating a domestic dishwasher and a computer program product.

Background

A domestic dishwasher is known, which has a dispensing device that can be equipped with a supply of detergent, wherein a suitable quantity of detergent is given in a program-controlled manner when a rinsing program is executed. This has the advantage that: the user does not fill the delivery unit with detergent before each execution of the rinsing procedure.

It can be proposed that: a domestic dishwasher has a dispensing device and a delivery unit. Thus, there are the following problems: it is not clear to the user which of the two systems is currently in use.

Disclosure of Invention

Against this background, the invention is based on the object of providing an improved domestic dishwasher.

According to a first aspect, a domestic dishwasher is proposed, having: a rinsing chamber; a control device for executing one of a plurality of flush procedures; a dispensing system comprising a delivery unit for containing a single dose of the first cleaning agent and delivering the single dose into the rinsing chamber at a dispensing point in time during the execution of the rinsing program; and an automatic dosing device for automatically dispensing a plurality of doses of a second cleaning agent present as a solid into the rinsing chamber at a dispensing point in time during the execution of the rinsing program. A sensor device is provided for detecting a state of the dispensing system and for outputting a sensor signal in dependence on the detected state of the dispensing system. The control device is arranged to execute a flushing program in dependence of the sensor signal.

The proposed domestic dishwasher has the following advantages: the use of a dispensing system with a delivery unit and an automatic dosing device enables in an intuitive way for a user: no complex programming steps are required. Thereby, on the one hand the user experience is improved and on the other hand the efficiency of the dishwasher is increased, since incorrect operation of the dishwasher is avoided.

The control device can be implemented in hardware and/or software technology. In the case of implementation in hardware technology, the control device can be configured, for example, as a computer or microprocessor. In the case of implementation in software technology, the control device can be designed as a computer program product, a function, a routine, a part of the program code or as an implementable object. The control device is arranged for executing one of a plurality of flushing programs. The number of flushing programs can be stored, for example, on a memory unit associated with the control device. The execution of the rinsing program can also be referred to as a rinsing process. In order to execute the respective washing program, the control device controls or actuates correspondingly provided functional units of the domestic dishwasher, i.e. for example valves, pumps, heating devices and/or a dispensing system, as a function of the washing program.

The dispensing system comprises in particular a delivery unit, which is arranged, for example, at the inner side of a door of a domestic dishwasher, which delivery unit is easily accessible to a user in the open state of the door. For example, the delivery unit has a container which can be closed with a flap and which is provided for receiving a quantity of the first cleaning agent. The first cleaning agent can be present here in the form of a powder, in the form of granules, in the form of tablets or also in the form of a liquid. Here, the user controls the amount of the first cleaning agent when filling the container, which is delivered as a single dose during the execution of the rinsing program. The maximum is in particular predetermined by the volume of the container. After filling, the user closes the container of the delivery unit with the flap. At the dispensing time, for example, the control device actuates the delivery unit such that the flap is opened and a single dose is dispensed into the rinsing chamber of the domestic dishwasher. In particular, a dispensing time is understood to be a time at which the cleaning agent is delivered during the running of the rinsing program. This point in time is for example at the beginning of the cleaning of the sub-program step.

Such a delivery unit has the advantages that: the user has complete control over: i.e. what amount and what type of first cleaning agent is used when performing the next rinsing program.

The dispensing system also has an automatic dispensing apparatus. The automatic dispensing device is advantageously provided with a reserve for containing the second cleaning agent. The second cleaning agent is especially present as a solid. For example, the second cleaning agent can be present as a powder, as a pellet, as a tablet, and/or in the form of a cleaning agent shaped body. The second cleaning agent is in particular loose or free-flowing. The first and second cleaning agents can be the same, but they can also be different. The store includes an amount of the second cleaning agent, the amount including a plurality of ingredient amounts. The dosage amount is especially sufficient for the rinsing process in the case of rinsing products as low as normal dirt. The stock comprises, for example, 20 dosage amounts, advantageously up to 50 dosage amounts. The supply can advantageously be stored in a removable storage container. The storage container can then, for example, be removed for filling and/or can be simply replaced by a pre-filled storage container.

At present, a cleaning agent is to be understood as meaning, in particular, a chemically active cleaning agent. The cleaning agent can also be or include a softening agent. The first or second cleaning agent can also comprise chemically inactive substances, i.e. for example abrasion agents.

For dispensing the doses, the automatic dosing device comprises, for example, a dispensing unit which is provided for removing the doses of the second cleaning agent from a storage or supply container and for supplying them to a rinsing chamber of the domestic dishwasher. The dosage amount includes, for example, 1-20ml or 1-20g of the second cleaning agent. Especially in the case of automatic dosing devices, a plurality of dispensing points in time can be provided in one rinsing program, so that at each point in time there is an optimum amount of detergent in the rinsing bath.

The delivery unit and the automatic dosing device are on the one hand interchangeable, wherein the user has the decision freedom to use the delivery unit or the automatic dosing device. On the other hand, the delivery unit and the automatic dosing device are complementary in that, for example, the second cleaning agent of the automatic dosing device comprises a standard cleaning agent which is suitable for cleaning the daily accumulation of rinsing goods. The transport unit can then be used for: when special requirements are placed on the cleaning of the rinsing goods, i.e. for example special properties of the rinsing goods and/or special properties of the contamination of the rinsing goods, a special cleaning agent is used as first cleaning agent.

Sensor devices for detecting the state of the dispensing system include, for example, optical, acoustic, electrical, mechanical and/or chemical sensors. For example, electrical contacts for detecting the supply container used, an acoustic and/or mechanical sensor for detecting the fill level of the second cleaning agent in the supply container, an optical sensor for detecting the presence of the first cleaning agent in the container of the delivery unit and/or a chemical sensor for detecting the type of the first cleaning agent in the container of the delivery unit can be provided.

The state of the dispensing system relates in particular to the presence of the first detergent as well as the second detergent. For example, the state can be defined by: there is no first detergent present in the delivery unit and a 250ml reserve of the second detergent is provided for the automatic dosing device.

The sensor device is arranged to output the detected state as a sensor signal. The control device is arranged to receive the sensor signal and to execute a flushing program in dependence on the sensor signal. In particular, the control device is provided for determining the state of the distribution system from the sensor signals, for example by evaluating the sensor signals. For example, the control device determines from the sensor signals: the dispensing system is in a state in which there is no first detergent in the delivery unit and a supply of 250ml of the second detergent is provided to the automatic dosing device. Subsequently, the control device executes, for example, a rinsing program, so that at the dispensing time point the automatic dosing device is actuated to dispense a dosing quantity into the rinsing chamber of the domestic dishwasher. Alternatively, it is also possible to provide: the control device selects and executes a dedicated flushing program from a plurality of flushing programs in dependence on the sensor signals. A dedicated flushing program can have a plurality of dispensing time points, for example, in particular when using an automatic dosing device. It can also be proposed: the dispensing time point is dynamically generated and/or the amount of the second cleaning agent dispensed is matched as needed. The amount dispensed can be adjusted, for example, by adapting the dosage amount or, in particular, by dispensing a plurality of times when the dosage amount has a fixed value. In this way the flushing result can be optimized.

For example, it is possible to propose: the control device preferably uses the delivery unit when it is filled with a single dose of the first cleaning agent. This can be referred to as a "manual override," for example.

According to a first embodiment of the domestic dishwasher, the state of the dispensing system comprises a manual state in which a single dose of the first cleaning agent is present in the delivery unit and an automatic state in which at least one dose of the second cleaning agent is present in the store and the first cleaning agent is not present in the delivery unit. The control device is arranged to: the delivery unit is controlled to deliver the first cleaning agent and/or the automatic dosing device is controlled to dispense a dosed amount of the second cleaning agent at a point in time of dispensing during execution of the rinsing program when the dispensing system is in the manual state, and the automatic dosing device is controlled to dispense a dosed amount of the second cleaning agent when the dispensing system is in the automatic state.

Advantageously, in this embodiment it can be provided that: the delivery unit is always used when the user fills the delivery unit with a single dose of the first cleaning agent before initiating the rinsing process. This simplifies the use of the dishwasher and avoids erroneous operation. In particular, programming the dishwasher, for example by operating an option switch, need not be performed. In addition to this example, many other applications of the control device are possible depending on the state of the dispensing system.

In order to detect the manual state, the control device is provided, for example, for recognizing whether a first cleaning agent is present in the delivery unit. If the first cleaning agent is present, the dispensing system is in a manual state. If the first cleaning agent is not present, the dispensing system is not in the manual state. For example, in a particularly simple embodiment, the automatic state can already be inferred from the detection of the manual state: if the dispensing system is not in the manual state, the dispensing system is in the automatic state. In this embodiment, the sensor device can be constructed particularly simply.

Preferably, the sensor device is additionally provided, for example, for detecting the automatic state, for identifying whether at least one dosed quantity of the second cleaning agent is present. If the supply of the second cleaning agent comprises at least the dosage amount and the dispensing system is not in the manual state, the dispensing system is in the automatic state. If at least one dose of the second cleaning agent is not present, the dispensing system is not in an automatic state.

If the automatic dosing device is provided for removably receiving a storage container, it is alternatively possible to take into account the presence of a storage container in the automatic dosing device. The dispensing system is then, for example, in an automatic state when the storage container is used and the first cleaning agent is not present in the delivery unit. In particular, it is possible to propose: the level of the second cleaning agent in the storage container is not taken into account here.

In addition or alternatively, a sensor device can be provided for detecting the fill level of the second cleaning agent in the storage container. The fill level can be detected, for example, as a percentage with respect to the maximum fill level, or else absolutely the weight or volume of the second cleaning agent. If a fill level that is not zero is detected, the presence of a reservoir is implicitly detected by this means. On the other hand, a level of zero or the absence of a reserve container in an automatic dosing device can mean: despite the use of the reservoir, the second cleaning agent is no longer present therein, i.e. the reservoir is empty.

According to a further embodiment of the domestic dishwasher, a user interface is provided for outputting user information depending on the sensor signal.

In this embodiment, for example, the user can be notified of: in which state the dispensing system is. By this, the user (if desired) can adjust the programming of the domestic dishwasher. In particular in the case of a dispensing system which is neither in the manual nor in the automatic state, it is possible to indicate to the user: neither the first nor the second cleaning agent is present.

The user information includes, in particular, not only the detected state of the distribution system in the described sense, but additionally also various other information. In particular, this is the fill level of the supply or the storage container, instructions for filling the supply or for replacing and/or filling the storage container, order information for filling the filled storage container or also an indication that a special cleaning agent needs to be filled as a first cleaning agent into the transport unit as a result of a special flushing program being selected, for example, for flushing goods made of high-grade steel. In this connection, the fact that the sensor signal is exceeded, i.e. for example, the user preselection of a flushing program to output user information by the user, can be taken into account

The user interface comprises, for example, a display screen and/or a data interface on the front side of the domestic dishwasher, in particular for wireless data transmission, i.e. for example WLAN,And/or a mobile radio interface. By means of the data interface, the user information can be transmitted, for example, to a connected device of the user, i.e., for example, a mobile device such as a smartphone or tablet computer, and output by the device accordingly.

According to a further embodiment of the domestic dishwasher, the automatic dosing device has a receiving unit for removably receiving a storage container for storing the second cleaning agent, and the control device is provided for detecting the presence of the storage container in the automatic dosing device and/or for detecting the fill level of the second cleaning agent in the storage container.

For example, the control device can have a mechanical or electrical switch for detecting the presence of the reservoir. For detecting the fill level, for example, the weight of the storage container can be detected, and/or the acoustic resonance frequency of the cavity in the storage container can be detected and/or the intensity decay of infrared light, for example, can be detected.

According to another embodiment of the domestic dishwasher, the sensor device is arranged for detecting a type of the first detergent and/or a type of the second detergent, and the control device is arranged for executing the rinsing program in dependence on the detected type of the first detergent and/or the detected type of the second detergent.

The type of cleaning agent is understood to mean, for example, the chemical composition, the formulation, e.g. liquid or solid, and/or the preferred rinsing procedure for using the cleaning machine. For example, the sensor device comprises a chemical sensor and/or an optical sensor to detect the type of detergent. In particular, the second cleaning agent stored in the storage container can be provided, for example, with a bar code on the storage container, in which information about the type of the second cleaning agent is encoded.

For example, the sensor device detects: a dedicated machine cleaner is filled into the delivery unit as a first cleaner. The control device thereby for example deduces that the user wishes to perform machine cleaning. As long as the domestic dishwasher is not loaded with rinsing goods, the control device advises the user and/or performs a selection for executing a dedicated machine cleaning program, for example. If, however, the domestic dishwasher is loaded with rinsing goods, the control device selects and executes a standard rinsing program, for example in the case of the use of an automatic dosing device. In particular, in this context, it is helpful to output user information by means of a user interface.

According to a further embodiment of the domestic dishwasher, the sensor device is provided for detecting an amount of the first cleaning agent forming a single dose, wherein the control device is provided for comparing the detected amount with a nominal amount and for executing a rinsing program depending on the comparison.

This embodiment advantageously ensures an optimal flushing result. By knowing the amount of first cleaning agent or the deviation from a predefined setpoint amount, the control device can optimally adjust the rinsing program, for example, the water amount used for the rinsing process, the water temperature, the pump speed and/or the duration of the rinsing process.

For example, below the nominal amount, it can be provided that: the automatic dosing device is controlled in addition to the dosing amount for delivering the second cleaning agent to compensate for the missing amount. Alternatively or additionally, the duration of the rinsing operation can be extended in order to achieve good rinsing results despite the small amount of first cleaning agent.

For example, in the case of an excess of the nominal quantity, the quantity of water used for rinsing is increased in order to ensure that the first cleaning agent is completely flushed from the items to be rinsed.

According to a second aspect, a method for operating a domestic dishwasher is proposed. A household dishwasher is provided with: a rinsing chamber; a control device for executing one of a plurality of flush procedures; a dispensing system comprising a delivery unit for containing a single dose of the first cleaning agent and delivering the single dose into the rinsing chamber at a dispensing point in time during the performance of the rinsing program; and an automatic dosing device for dispensing a plurality of doses of a second cleaning agent present as a solid into the rinsing chamber at a dispensing point in time during the execution of the rinsing program. In a first method step, the state of the dispensing system is detected by means of a sensor device. In a second method step, a sensor signal is output depending on the detected state of the dispensing system. In a third method step, a rinsing program is executed as a function of the sensor signal.

The method can advantageously be performed with a domestic dishwasher according to the first aspect.

In particular, the control device dynamically adjusts the flushing program in the proposed method in order to ensure an optimal flushing result. This is understood, for example, as: the parameters of the rinsing program to be executed, in particular the dispensing point in time or points defined therein, can be changed, overwritten, deleted and/or added by the control device.

Furthermore, a computer program product is proposed, which causes the above-described method to be performed on a program-controlled device.

The computer program product, i.e. for example the computer program medium, can be provided or delivered, for example, as a storage medium, i.e. for example a memory card, a USB stick, a CD-ROM, a DVD or also in the form of a file that can be downloaded from a server in a network. This can be achieved, for example, in a wireless communication network by transmitting a corresponding file with a computer program product or a computer program medium. Files can also only be streamed, i.e. the files are not stored on the target device but are processed directly.

The embodiments and features described for the proposed domestic dishwasher are correspondingly applicable to the proposed method.

Other possible embodiments of the invention also include combinations of features or embodiments not explicitly mentioned before and below in connection with the examples. The person skilled in the art will also add separate aspects here as an improvement or supplement to the corresponding basic form of the invention.

Drawings

Further advantageous embodiments and aspects of the invention are the subject matter of the dependent claims of the invention and of the embodiments described below. Furthermore, the present invention is explained in detail with reference to the drawings according to preferred embodiments.

FIG. 1 shows a schematic perspective view of an embodiment of a domestic dishwasher; and

fig. 2 shows a schematic block circuit diagram of an exemplary embodiment of a method for operating a domestic dishwasher.

In the figures, identical or functionally identical elements are provided with the same reference symbols, unless otherwise indicated.

Detailed Description

Fig. 1 shows a schematic perspective view of an embodiment of a domestic dishwasher 1. The domestic dishwasher 1 comprises a rinsing container 2, which can be closed, in particular watertight, by a door 3. For this purpose, a sealing device can be provided between the door 3 and the rinsing container 2. The rinsing container 2 is preferably square. The rinsing container 2 can be arranged in a housing of the domestic dishwasher 1. The rinsing container 2 and the door 3 can form a rinsing chamber 4 for rinsing the rinsing goods 15.

The door 3 is shown in its open position in fig. 1. The door 3 can be opened or closed by pivoting about a pivot axis 5 provided at the lower end portion of the door 3. The filling opening 6 of the rinsing container 2 can be closed or opened by means of the door 3. The rinsing container 2 has a bottom 7, a top 8 arranged opposite the bottom 7, a rear wall 9 arranged opposite the closed door 3, and two side walls 10, 11 arranged opposite each other. The bottom 7, the top 8, the rear wall 9 and the side walls 10, 11 can be made of, for example, high-grade steel. Alternatively, the bottom 7 can be made of a synthetic material, for example.

The domestic dishwasher 1 also has at least one wash-ware receptacle 12 to 14. Preferably, a plurality of, for example three, rinsing product receptacles 12 to 14 can be provided, wherein rinsing product receptacle 12 can be a lower rinsing product receptacle or lower basket, rinsing product receptacle 13 can be an upper rinsing product receptacle or upper basket, and rinsing product receptacle 14 can be a cutlery drawer. As also shown in fig. 1: the flushing article receptacles 12 to 14 are arranged in the flushing container 2 one above the other. Each flushing article receiving section 12 to 14 can be selectively moved into and out of the flushing container 2. In particular, each flushing-article receptacle 12 to 14 can be pushed into the flushing container 2 in a push-in direction E and can be pulled out of the flushing container 2 in a pull-out direction a counter to the push-in direction E.

Furthermore, the domestic dishwasher 1 has a control device 100. The control device is in particular designed as a central control unit which is responsible for controlling all controllable components or units of the domestic dishwasher 1.

In this embodiment, a dispensing system 110 is also arranged at the inner side of the door 3, the dispensing system comprising a delivery unit 112 and an automatic dosing device 114. The delivery unit 112 is provided for containing a single dose of the first cleaning agent. For example, the transport unit 112 has a chamber which can be closed by means of a closure element (e.g., a flap). The delivery unit 112 is provided by the control device 100 for opening the flap to release a single dose of the first cleaning agent contained in the cavity.

The automatic dosing device 114 comprises in this example a receiving unit (not shown) for receiving a removable storage container, which is provided for storing the second cleaning agent. The storage container for example contains a quantity of the second cleaning agent which corresponds to 50 dosage quantities, wherein a dosage quantity for example comprises 5ml or 5g of the second cleaning agent. The automatic dosing device 114 also has, for example, a dispensing unit which is provided for dispensing a dosed amount of the second cleaning agent from the storage container. For example, the reserve container is pivotably or rotatably arranged in the receiving unit. Alternatively, the receiving unit may be pivotably or rotatably arranged. The dispensing unit is then provided for dispensing the dosage amount, for example for pivoting or rotating the supply container. For example, the dispensing of the dose of the second cleaning agent is performed by rotating the reservoir through an angle of rotation of between 180 ° and 360 ° in a particular direction of rotation. If a greater amount of second cleaning agent than ingredient amount is desired, this can be accomplished by operating the automatic ingredient device 114 multiple times.

The domestic dishwasher 1 has a sensor device 120 which is provided for detecting a state of the dispensing system 110. For example, the sensor device 120 includes three sensors: a first sensor arranged to detect the presence of a first cleaning agent in the delivery unit 112; a second sensor arranged to detect the type of the first cleaning agent; and a third sensor arranged to detect the level of the second cleaning agent in the storage container. In this example, the state of the dispensing system 110 is given by the totality of the sensor data detected by the three sensors. The sensor device 120 is further arranged for: the detected state is output as a sensor signal, in particular to the control device 100.

The control device 100 is provided for receiving sensor signals and for example also for deriving a state of the distribution system 110 from the received sensor signals. Furthermore, the control device 100 is provided for executing a flushing program as a function of the received sensor signals, in particular as a function of the state of the dispensing system 110.

For example, the user delivers the articles of washware to the domestic dishwasher 1 and fills the delivery unit 112 with a single dose of the first cleaning agent. Subsequently, the user initiates a normal flush procedure. The sensor device 120 detects: the first detergent is present in the delivery unit 112 and outputs a sensor signal. In an embodiment, the control device 120 can also be provided, for example, for detecting the amount of first cleaning agent in the delivery unit 112. The control device 100 initiates a normal flushing procedure. At the dispensing time of the normal rinsing program, the control device 100 actuates the dispensing system 110 or the delivery unit 112 such that it delivers a single dose of the first cleaning agent into the rinsing chamber 4, wherein the dispensing time is in particular at the beginning of the cleaning of the sub-program step. If the amount of first cleaning agent is too small, for example, it is possible to provide: the control device 100 additionally actuates the automatic dispensing device 114 at a second dispensing time point to give a dosed quantity of the second cleaning agent. The second allocation point in time can be the same as the first allocation point in time, but the second allocation point in time can also be subsequent to the first allocation point in time.

Fig. 2 shows a schematic block circuit diagram of an exemplary embodiment of a method for operating a household dishwasher 1, for example the household dishwasher 1 of fig. 1. In a first method step S1, the sensor device 120 (see fig. 1) detects a state of the dispensing system 110 of the domestic dishwasher 1. For this purpose, the sensor device 120 can have a plurality of individual sensors. The individual sensor can, for example, output an analog voltage signal, the voltage value of which is correlated in a known manner with the measured variable, or a voltage signal which has two different levels and thus distinguishes two well-defined states. Additionally or alternatively, the sensor can also show a digital data signal.

In a second method step S2, the sensor device 120 outputs the detected state of the dispensing system 110 as a sensor signal. The sensor signal can comprise an analog voltage signal and/or a digital data signal. The sensor signal is in particular designed such that a detected state of the dispensing system 110 can be inferred from the sensor signal.

In a third method step S3, the control device 100 (see fig. 1) executes a flushing program as a function of the sensor signal. Among these, in particular: the control device 100 receives the sensor signal and derives the state of the dispensing system 110 from the sensor signal. This can be achieved, for example, by evaluating the sensor signal or scanning the sensor signal. Depending on the state of the distribution system 110, the control device 100 selects: whether the detergent should be delivered using the delivery unit 112 or the automatic dosing device 114. For this purpose, the control device 100 can store, for example, a look-up table in which: which flush procedure should be executed in the respective state. Alternatively or additionally, it can be provided that: the control device 100 evaluates a calculation formula that outputs an optimal flushing program according to the state. The optimum program can in this case include, inter alia, individually adapted parameters, such as the operating time, the water quantity and/or the water temperature, the nominal quantity of cleaning agent, one or more dispensing points in time for delivering the first and/or second cleaning agent, etc.

Although the present invention has been described in terms of embodiments, various modifications can be made thereto.
