Description

"Dosing device and household appliance, in particular dishwasher"

The invention relates to a metering device according to the preamble of claim 1 and a household appliance, in particular a dishwasher.

From the state of the art, water-conducting domestic appliances, in particular dishwashers, are known, for example from the publication DE 10 2006 043 974 A1, which comprises a container for a storable amount of cleaning agent. Furthermore, the document DE 10 2006 043 973 A1 discloses a water-conducting domestic appliance, in particular a dishwasher, with a container for holding cleaning agents and with a device for detecting the filling level. From the document DE 10 2006 043 913 Al it has become known to form such containers as multi-chamber systems.

The object of the invention is to propose an improved dosing device for the dosing of cleaning, washing or rinsing agents in household machines, in particular dishwashers, as well as a corresponding household appliance, in particular a dishwasher.

Starting from a metering device or a household appliance of the type mentioned, the object is achieved by the characterizing features of claim 1 In the dependent claims advantageous embodiments and further developments of the invention are named and explained.

Accordingly, a dosing device according to the invention is characterized in that there is at least one wireless connection to the control unit of a household appliance and / or to the power supply.

Domestic machines such as cleaning machines, washing machines and especially dishwashers usually require a metering device which takes over the dosage of cleaning, washing or rinsing agent. The use of a wireless connection to the control unit of the household machine, for example, allows the transmission of control commands, data or other signals without being dependent on a hardwiring. Furthermore, the power supply of the metering device can be ensured via a wireless connection. The ever increasing demands on insulation of live or live parts, even if it is, for example, only very low currents or voltages, can thus be met in a particularly elegant manner. Also, for example, additional contacts for connectors can be avoided, as well as the associated wear and tear. Accordingly, with such dosing devices, a high degree of safety and reliability can be achieved.

In a particularly advantageous embodiment of the invention, the metering device can be introduced as a separate unit from the household appliance in the working space of the household appliance. The advantage of this is that the household appliance does not necessarily have to include its own metering device. The metering device is a completely separate unit and can be easily replaced if necessary, without the need for example a structural intervention in the household appliance would be necessary. In principle, this also creates the opportunity to use the same metering device in several household appliances or to operate several metering devices in a household appliance. Often, different items to be cleaned also require different cleaning programs. Another advantageous application possibility could be that, for example, a separate metering device for stubborn dirt can be used in the same machine, while a metering device for gentle cleaning, for example, comes into play for sensitive objects in the same machine. Under certain circumstances, such a unit could already be sold with the detergent.

Since the domestic appliance is a water-conducting appliance, in one embodiment of the invention it is preferable to tune at least one wireless connection to a water-transmitting frequency. As a result, disruptive effects of the water in the vicinity of the metering device can be reduced or completely reduced.

In the case of electromagnetic transmitters or receivers, a frequency in the interval between 110 kHz and 140 kHz is particularly selected. In particular, a frequency at about 125 kHz has been proven for trouble-free transmission in water.

Depending on the type of application, a dosage of the cleaning agent can be simple or very expensive. In most cases, however, it is desired not to randomly dose during a rinse cycle. Therefore, it is advantageous to provide a metering control unit in one embodiment of the invention. These For example, it may be designed so that it controls the dosage according to appropriate specifications or else so that regulation is provided on the basis of certain parameters.

In one development of the invention, for example, the control unit for receiving and / or transmitting signals of the household machine can be formed via a wireless connection. This embodiment can pursue several objectives, for example, commands from the machine control of the domestic appliance for metering to the control unit of the metering device can be transmitted. Among other things, thus, for example, the information to the metering device could be passed, for example, when the operation of the household machine is interrupted by sudden opening of the loading door, for example, to bring another object to be cleaned in the work space. In this case, the machine controller may notify the metering device that it is desired to discontinue the metering or dispensing of the detergent but, for example, that a complete restart of the metering program is not required. In the reverse manner, however, the dosing device could also pass on corresponding commands or data to the household appliance, in particular the machine control or a storage unit of the household appliance. For example, it would be conceivable to provide a separate metering device for carrying out a special cleaning program, for example for heavily soiled articles. In principle, the course of this cleaning program could also be controlled by such a metering device, provided that it is designed accordingly. The dosing device could specify the machine control of the household machine, for example, how high the water temperature must be or how long a section of a corresponding rinse cycle has to last. But it is also conceivable that a transmission simple data eg also of identification or product numbers are transmitted. The direction in which the transmission takes place or whether even a mutual exchange of data or commands can or should take place depends on the individual embodiment of the invention.

As a rule, a metering device for controlled metering requires a power supply unit for the power supply. For example, this can be understood as a voltage source.

In a particular embodiment of the invention, the power supply is provided via a wireless connection from the household appliance. In doing so, one can take advantage of similar advantages both in terms of safety standards and reliability of the metering device, as already mentioned in connection with wireless connections.

In an advantageous embodiment of the invention, a capacitive or inductive energy transfer is provided. A capacitive energy transfer takes place via the charging of a capacitor plate, while in the case of an inductive energy transfer in a coil or an inductance, voltages are induced by a magnetic alternating field. Both are elegant solutions of a contactless energy transfer.

Likewise, in one embodiment of the invention, the power supply unit may include a battery. The battery could be charged for example by a charger. However, it is also conceivable to continue to use a wireless connection as a power supply and to charge the battery, thus to use it as an energy store. Amongst other things, it is advantageous that the metering device is at least in the charged state of the Energy storage does not stop immediately when an external power supply, even if it is short term, is interrupted. In addition, this energy can also be saved if, for example, the metering device just does not require energy, but still takes place an energy transfer to the metering device.

A particularly preferred development of the invention provides that the energy supply unit comprises a connection device for connection in the work space or at the feed door of the household appliance. There are a variety of possibilities for attachment, such as to devices in the work space at the loading door or, for example, in a corresponding slot in or on the loading door.

In a variety of household appliances and operating errors are possible, for example, a user could use a metering device, which is not suitable for the corresponding household machine, in which the metering device is to be introduced. This could lead to incorrect dosages, but also to damage to the household appliance or the metering device. It is also conceivable that a wrong cleaning agent is used by the user. Again, it could in principle come to the above damage, but could also be drawn by such incorrect operation, the objects to be cleaned in the affected. Therefore, in a particularly preferred embodiment of the metering device, a coding unit is present. In principle, the dosing device could also recognize via such a coding unit whether it is suitable, for example, for operation in such a household appliance or whether the detergent supplied to it can be used. For example, an activation of the dosing device could take place Prerequisite for the commissioning of the metering device is.

In a preferred embodiment of the invention, the coding unit may be designed to receive and / or transmit signals via a wireless connection. By sending, receiving or even exchanging signals, the dosing device or the household appliance or even both could determine whether there is a compatibility problem or a corresponding incorrect operation or whether the operation can be started. For example, if the dosing device does not receive a corresponding activation signal, no operation is possible. Likewise, a similar operation could also be possible within the appliance.

In order to realize a corresponding wireless connection, it is advantageous to use established technical systems, in particular if these are commercially available and correspondingly favorable. Therefore, in an advantageous development of the invention, the coding unit is designed as a Bluetooth system. This is usually characterized by a relatively high reliability. In addition, Bluetooth systems are relatively small and can be integrated virtually anywhere.

A particularly simple and inexpensive possibility for realizing a coding system is, in an advantageous embodiment of the invention, to form the coding unit as a mechanical coding unit. Such a mechanical coding can for example be realized in that the metering device has a special shape, which can be introduced only in special recording devices. However, it is also conceivable both exclusively and in addition to provide for this fits and corresponding dowel pins, specify these in a special arrangement, but possibly also to apply pressure contacts, which can be operated only when introducing a suitable metering device. Furthermore, the mechanical coding has the advantage that in most cases it can also be used as an additional coding means when using other coding units.

In a further development of the invention, at least one sensor for the dosage control is present. As sensors, a wide variety of types of sensors may be used, such as temperature sensors, humidity sensors, pH sensors, level sensors, conductivity sensors, microphones, etc. The use of such sensors may be of particular importance, e.g. via the control unit, the dosage should be made adjustable.

In a development of the invention, the control unit is self-sufficient, in particular independent of the household appliance. One possibility for this is that the control unit controls the dosage in accordance with fixed specifications. It is also particularly advantageous, for example by the use of sensors, to make the dosage controllable. In both cases, in principle, a self-sufficient operation of the control unit can be given. In particular, however, allows the use of sensors that the dosage is adapted to the current and individual conditions in the working space of the appliance. A regulation could be carried out, for example, if cleaning parameters such as temperature or pH, deviations from the ideal value, which should in principle be achieved during a rinsing cycle, have. The advantage of this is that a particularly good rinsing result can be achieved. In addition, regardless of the household machine again and again different and under Could also be used again and again improved and adapted washing programs without the household machine would have to be replaced.

Furthermore, in an advantageous embodiment of the invention, the power supply unit can operate autonomously, in particular independently of the household appliance.

In addition, in one embodiment of the invention, at least one chamber for receiving a cleaning agent is present. Depending on the manufacturer's specification, for example, the cleaning agent could be refilled in such a chamber. However, it could also be replaced individual parts, chambers up to the entire metering device with used up detergent. For some wash programs it is advantageous to use different detergents within a wash cycle. Accordingly, in an embodiment of the invention, a plurality of chambers may be available. In particular, these could also be controlled separately from the control unit for metering.

In a particularly preferred embodiment of the dosing device according to the invention, the at least one chamber for receiving the at least twice the dose, which is necessary for a rinsing cycle, formed. This means, inter alia, that the dosing device can be used for at least two rinsing cycles. As a result, the possibility can be created of using such a dosing device for a plurality of rinsing cycles, without having to replace the cleaning agent up to the entire dosing device after each individual rinsing cycle.

Nevertheless, if the cleaning agent is used up after a certain time, it may, for example, be advantageous having to refill individual detergents, which sometimes can be complex, since even a skin contact with various detergents is not always completely safe, but at least provide a replaceable unit comprising a container for receiving at least one detergent for at least two rinsing cycles. Such exchangeable units can be made easy to handle, if necessary even direct skin contact with the cleaning agent can be avoided. How many chambers and which size the individual chambers have remains the particular desired embodiment of the invention. In principle, the embodiments of the invention also include the use of liquid or solid detergents.

In an advantageous embodiment of the invention, the container comprises at least one chamber for receiving a cleaning agent, in particular, the container may therefore also be designed as a multi-chamber system.

A particularly preferred development of the invention provides for the control unit or the energy supply unit or the coding unit to be designed such that they have a double insulation of water-bearing spaces. Advantageously, a particularly high safety standard is achieved.

A further development of this is to integrate the control unit, the power supply unit or the coding unit into a watertight capsule. Advantageously, such a capsule can be sealed particularly well by common industrial processes such as, for example, welding, ultrasonic welding or else bonding. In principle, a casting of the corresponding components in a capsule is conceivable. Advantageously, capsules can also be inserted into walls of structural units. Furthermore, a domestic appliance according to the invention, in particular a dishwasher, is characterized in that at least one wireless connection to a metering device according to one of claims 1 - 24 is present. Such a household machine allows a particularly advantageous use of a corresponding metering device. There are various ways to exploit advantages of the invention or the corresponding embodiments of the invention. On the one hand, it is possible to use embodiments of the metering device according to the invention, which, for example, certain functions that are usually fulfilled by household appliances, to make unnecessary and thus to allow cost savings in the production of household appliances. An example of this is a corresponding metering device, which independently or at least largely independently takes over the control of the dosage. On the other hand, it is possible, for example, to reduce the risk of incorrect operation by means of appropriate coding units. Furthermore, there is also the possibility to control the dosage about the machine control of the household machine. Overall, depending on the wishes and needs of different tasks or functions of the metering device or the household machine can be assigned or certain synergies are created, for example, a data exchange are possible or a collaboration of coding units.

In an advantageous embodiment of the invention, the device for producing a wireless connection for generating an alternating magnetic field for power supply is formed. This can be realized, for example, by the fact that corresponding devices for generating an alternating magnetic field, so coils or permanent magnets in a rotor, in particular the rotor for wetting objects to be cleaned, is integrated.

Some wireless connections require positions of transmitter and receiver, transponder and reader, coils or capacitor plates, etc. to each other for particularly good operation. This may be due to a corresponding short-range of the respective transmission, but also because the direction of the field lines is important, e.g. with inductive or capacitive energy transfer. Therefore, it is advantageous to provide a receiving device for receiving the metering device in the working space, in particular to allow the most constant possible operation during the individual rinsing cycles, and thus to obtain a consistently good cleaning result.

In a particularly preferred domestic machine, the receiving device comprises a key unit associated with the mechanical coding unit. By coding it can be achieved that the correct metering device used and thus an incorrect operation is avoided as possible. If this is required in a corresponding embodiment of the invention, the mechanical coding can also be designed such that only certain orientations of the metering device are allowed when they are introduced into the working space.

In a particularly preferred embodiment of the household appliance, a charging device is provided for charging the batteries of the metering device. This can be realized in particular by the said possibilities of wireless connection.

To power the metering device is advantageously a wireless power supply possible, in particular for the capacitive or inductive transmission of energy.

FIG. 1 shows a dishwasher 1 with an opened loading door 3. Through the opened loading door 3, the view into the working space 4 is released. In this working space 4 baskets 5 can be seen, in which dishes to be cleaned 8 can be made. In addition, a rotor 9 can be seen in the working space 4, which e.g. ensures the wetting of the dishes to be cleaned 8. At the top of the dishwasher 1, a control unit or machine control 6 of the dishwasher 1 is indicated. To this control unit 6, an antenna 7 is connected, which extends laterally from the working space 4. One of the baskets 5 comprises a placement device 10. A dosing device 2 is introduced into this. The dosing device 2 comprises a hexagonal housing 2A.

A similar dishwasher I ¹ is shown in FIG. FIG. 2 shows an overall side view of the dishwasher 1 'when the loading door 3' is open. The working space 4 and the therein baskets 5 and the dishes to be cleaned 8 are indicated by dashed lines.

Figure 3 shows a dishwasher I ^{1 1} with an open loading door 3 '' and a working space 4 ^{1 1} . By the look In the working space 4 ¹ 'you can see corresponding baskets 5 and dishes to be cleaned 8. On a side wall in the interior of the working space 4 ^{1 1} is the placement device 10'', in which a hexagonal dosing device 2''is introduced. The dishwashers 1, 1 'and I ¹ ' shown in FIGS. 1, 2 and 3 are essentially very similar domestic appliances, but in which only the metering devices 2, 2 'and 2 ¹ ' are at different locations in the working space 4 , 4 'and 4 ¹ ' is mounted. A more detailed diagram of a metering device 2 is shown in FIG. The metering device 2 is in one

Placement device 10 introduced. The dosing device 2 also comprises a power supply unit 11 for inductive energy transmission, a control unit 14 which is connected to a Bluetooth antenna 12 and controls the dosage of cleaning agents 18. The electrical device of control unit 14 with Bluetooth antenna 12 is encapsulated, wherein the encapsulation 29 is indicated by a dashed line. Furthermore, the dosing device 2 comprises a multi-chamber system 15 with individual chambers 16 for storing cleaning agents 18. Preferably, the chambers 16 are designed such that they can store at least twice the dose needed for a rinsing cycle. This multi-chamber system 15 is controllable via the control unit 14 with respect to the dosage. The chambers 16 further comprise chamber doors 17, which can be opened for metering and ensure that corresponding cleaning agents 18, whether liquid cleaning agents or solids cleaners, can get into the working space 4. For data transmission to or from the Bluetooth antenna 12, an antenna 7 is provided in the dishwasher 1.

One way to make the power supply of the metering device 2 wireless, is illustrated in Figure 5. To see is a rotor 9, which can rotate in the direction of rotation 22. On the rotor blades of the rotor 9 permanent magnets 21 are integrated. The rotor 9 itself serves in a dishwasher 1 to wetting the dishes 8 to be cleaned during a rinsing cycle. In the immediate vicinity of the rotor 9, the metering device 2 is mounted in a placement device 10. The energy supply unit 11 for inductive energy transmission is placed in such a way that the field lines of the permanent magnets 21 can penetrate the coil and thus can induce a voltage.

FIG. 6 shows how a metering device 2 with corresponding coding units 19, 24 can be introduced into a placement device 10 with coding units 20, 23. The dosing device 2 is hexagonal and fits with its shape exactly in the placement device 10. In addition, the placement device 10 includes dowel pins 23, which additionally ensure that the dosing device 2 is inserted with corresponding fits 24 with the correct orientation in the placement device 10. Furthermore, the dosing device 2 comprises an RFID transponder 19 and the placement device 10 comprises a corresponding RFID reader 20.

FIG. 7 shows an embodiment of a metering device 2 with an exchangeable unit 26. The replaceable unit 26 is used here for the storage of cleaning agents 18. The metering device 2 is designed such that it comprises a console 25, in which the replaceable unit 26 can be introduced. In this embodiment, the console simultaneously comprises the power supply unit 11, the control unit 14 with a Bluetooth antenna 12 and a corresponding encapsulation 29 of the control unit 14 and the Bluetooth antenna 12. The control unit 14 is used in the Essentially the control of the dosage. The console 25 has next to a recess for introducing the replaceable unit 26 dowel pins 30. In the replaceable unit 26 corresponding fits 31 are provided. In addition, the replaceable unit 26 comprises an RFID transponder 27 while the console 25 has an RFID reader 28 with a warning device 33 connected thereto and a warning LED 34.

Figure 8, however, shows a metering device 2 with a plurality of metering chambers 16, a control unit 14 for controlling the dosage, to which a Bluetooth antenna 12 is connected. To make the dosage self-sufficient, that is independent of a dishwasher 1, a sensor 32 is connected to the control unit 14 further. These may be different types of sensors 32, such as a pH sensor, a temperature sensor, or the like. In principle, a plurality of sensors 32 can also be connected to such a control unit.

Depending on the embodiment of a dishwasher 1, 1 'and I ^{1 1} metering devices 2, 2 ¹ or 2 ^{1 1} at different points in the working space 4, 4' and 4 ¹ 'are introduced. The selection is essentially related to the design and design of corresponding dishwasher 1, 1 ', I ^{1 1} and can be adjusted depending on the type of machine so as to ensure either short distances for wireless connections or around the corresponding machine type, the detergent 18 at the optimal Make the job recoverable. Another reason for placing a dosing device 2 at a specific location could also be due to the fact that corresponding sensors 32 can operate at points representative of measurements in a working space 4, for example in the vicinity of the dishes 8 to be cleaned.

FIG. 4 shows a metering device 2, for example the control unit 14 for metering cleaning agents 18 is connected to the machine control 6 via a Bluetooth connection. This could mean, for example, that the machine controller 6 transmits commands for metering to the Bluetooth antenna 12 via the antenna 7, wherein the control unit 14 can make a corresponding metering during the corresponding flushing cycle. Likewise, it is also possible that the control unit 14 automatically assumes a metering control, for example according to a predetermined program, and that the Bluetooth connection is merely used to transmit a coding to the machine control 6, by means of which it can be determined, for example, whether the metering device 2 is connected to the household appliance 1 is compatible.

In Figure 5, an inductive power supply is shown, instead of a rotor 9 to be cleaned harness 8 is used. Instead of a rotor 9, whose basic function is the wetting of dishes to be cleaned 8, at the same time use for energy supply, a specially designed for the power supply rotor can be used.

In particular, coding units can be very useful in order to avoid incorrect operation. It has already been mentioned that, for example, a Bluetooth antenna 12 can also be used for the transmission of corresponding coding signals and thus, for example, a device identification is made possible with a wireless connection to the machine control 6. A technical, usually simple realization of a coding is to provide mechanical coding units. In Figure 6, the metering device 2 is formed hexagonal and has with the placement device 10 has a correspondingly suitable recording form. In addition, such a coding can be assisted by the presence of dowel pins 23 and corresponding fits 24. Both by a corresponding form of a metering device 2 as well as by appropriate dowel pins 23 and associated fits 24 can also be an orientation of the metering device 2 when inserted into a

Placement device 10 can be specified so that a user has no choice but to

Use dosing device in the correct way. Another possibility is to realize a coding unit via a wireless connection. Particularly advantageous is the use of RFID transponders, which can be purchased inexpensively and are miniaturized so that they can be integrated virtually anywhere. Accordingly, in FIG. 6, an RFID transponder 19 is installed in the dosing device 2. The placement device 10 comprises a corresponding RFID reader 20. The transponder 19 is addressed if the electromagnetic wave emitted by the reader 20 has such a frequency that a resonance is achieved in the transponder 19. The transponder 19 may also include a microchip, which further transmits, for example, in such a case, an electrical signal, such as a warning in case of incorrect operation or an "OK" signal when using the dosing device 2. It can also use such a microchip Storage units may be present, for example, to the number of rinsing cycles for which a corresponding metering device 2 has been used to hold. In principle, the microchip could also pass signals to a control unit 14, for example so that it is activated and can cause a metering during a rinsing cycle. Another embodiment is to equip either fits 24 or dowel pins 23 with contacts such as buttons, so that, for example, an activation of a control unit 14 is carried out at the same time when properly introduced the dosing device 2. If the cleaning agent 18 is used up after a certain time, it must either be filled in a metering device 2 or at least a part of the metering device 2, which receives the cleaning agent 18, be renewed. In general, it is preferable to provide a replaceable unit 26 for this purpose, so that at least skin contact with cleaning agents can be minimized or possibly avoided altogether. Such a replaceable unit 26 may also include corresponding coding units. For example, in this case, the replaceable unit 26 includes fits 31 for corresponding dowel pins 30 inserted in the console 25. Basically, the recess in the bracket 25 is provided so that the replaceable unit 26 can be inserted. Furthermore, the replaceable unit 26 comprises an RFID transponder 27, which can be addressed by a reader 28 in the console 25. Furthermore, a warning device 33 is connected, which lights up a warning LED 34 in the event of an incorrect operation. An interchangeable unit 26 suitable for insertion into the console 25 must also be designed so that metering, in this case eg opening of the chamber doors 17, can be caused by a control unit 14, in this case in the console 25.

FIG. 8, on the other hand, shows that a metering device 2 is connected to sensors 32, which are connected to the control unit 14, for example. It is conceivable to design such a metering device 2 in such a way that the metering can proceed completely autonomously, ie independently of the dishwasher 1. For example, a corresponding flushing cycle can be detected by a sensor measuring the temperature. Other detection values are, for example, the pH or the humidity. By means of the control unit 14, a program in the rinsing cycle can be detected with appropriate measured values, a dosage can be started or Also, an already made dosage to be corrected if, for example, the pH does not correspond to a desired value. As a sensor 32, a photosensor can be used to detect, for example program start or end or even a program interruption or -weiterführung when opening the loading door 3. It is also conceivable that corresponding data on the coding unit 14 and, for example, the Bluetooth device 12 and the antenna 7 is passed to the machine control unit 6 of the dishwasher 1. One possibility would be to notify the machine controller 6, for example, that the temperature in the working space 4 does not correspond to a desired temperature, so that the machine control 6 can initiate corresponding countermeasures.

All embodiments and further developments of the invention have in common that there is at least one wireless connection to the control unit of the household appliance and / or to the energy supply.
