- a sensor 32 is connected to the control unit 14 further.
- sensors 32 such as a pH sensor, a temperature sensor, or the like.
- a plurality of sensors 32 can also be connected to such a control unit.
- metering devices 2, 2' or 2 can be introduced at different locations in the working space 4, 4 'or 4 ".
- the selection depends essentially on the type and design of corresponding dishwashers 1, I ', 1 "together and can be adapted depending on the type of machine so as to either provide short paths for wireless connections or to make the detergent 18 at the optimal location can be introduced at the appropriate machine type.
- Another reason for placing a dosing device 2 at a specific location may also be due to the fact that corresponding sensors 32 are provided at points representative of measurements in a working space 4, e.g. in the vicinity of the dishes to be cleaned 8, can work.
- FIG. 4 shows, for example, a metering device 2 in which the control unit 14 for metering cleaning agents 18 is connected to the machine control 6 via a Bluetooth connection.
- the control unit 14 for metering cleaning agents 18 is connected to the machine control 6 via a Bluetooth connection.
- 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.
- the control unit 14 to independently assume a metering control according to a predetermined program, for example, and to use the Bluetooth connection merely to transmit an encoding to the machine controller 6, by means of which e.g. It can be determined whether the metering device 2 is compatible with the household machine 1.
- an inductive power supply is shown, instead of a rotor 9 to be cleaned harness 8 is used.
- a rotor 9 whose basic function is the Wetting of dishes to be cleaned 8 is to use at the same time for energy supply, a specially designed for the energy supply rotor can be used.
- 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.
- the metering device 2 is formed hexagonal and has with the placement device 10 has a correspondingly suitable recording form.
- a coding can be assisted by the presence of dowel pins 23 and corresponding fits 24.
- Both by a corresponding shape of a metering device 2 and by corresponding dowel pins 23 and associated fits 24 also an orientation of the metering device 2 when inserting into a placement device 10 can be specified so that a user has no choice but to use the metering device in the correct way.
- Another possibility is to realize a coding unit via a wireless connection. Particularly advantageous is the use of RFID T ranspondern, which can be purchased inexpensively and are miniaturized so that they can be integrated virtually anywhere.
- 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 is further described below as 2.B. in such a case transmits an electrical signal, e.g. a warning in case of incorrect operation or an "OK" signal when using the dosing device 2 as prescribed.
- memory units may also be present, for example in order to record the number of rinsing cycles for which a corresponding dosing device 2 was used.
- the microchip could also pass on signals to a control unit 14, for example so that it is activated and a dosage during a Rinsing cycle can cause.
- 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.
- the cleaning agent 18 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.
- 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.
- 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.
- the replaceable unit 26 comprises an RFID transponder 27, which can be addressed by a reader 28 in the console 25.
- 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 a dosage, in this case e.g. Opening the chamber doors 17, by a, in this case mounted in the console 25 control unit 14, can be caused.
- Figure 8 shows that a metering device 2 with sensors 32, e.g. are connected to the control unit 14. 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.
- a corresponding flushing cycle can be detected by a sensor measuring the temperature.
- Other detection values are, for example, the pH or the humidity.
- a program in the rinsing cycle can be detected with appropriate measured values, a dosing can be started, or a dosing already made can be corrected if, for example, the pH does not correspond to a desired value.
- a photo sensor can be used, for example, program start or end or even a program interruption or -weiter arrangement when opening the To recognize 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 inform 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 appropriate countermeasures.
- a connection from the dishwasher 35 to the metering device which consists of a metering unit 37 and a tank 36, which is designed as a replacement unit consists.
- the connection between the household machine 35 and the tank 38 or the connection 39 between the domestic machine 35 and the dosing unit 37 may also be provided.
