- a microswitch for controlling the drive can detect the position of the reversing device.
- the object of the invention is to provide a method for operating a dishwasher, which allows in a relatively simple manner to recognize the current position of the switching device.
- Another object of the invention is to provide a correspondingly designed dishwasher.
- the object of the invention is achieved by a method for operating a dishwasher, comprising the following method steps:
- Adjusting the position of a reversing device of a dishwasher in addition to the Um Strukturvorraum a rinsing container, at least two arranged within the Spippobefflefflel- ters spraying devices, a circulation pump for conveying liquid to the spraying devices and a first drive for driving the circulation pump, wherein the circulating pump depending on the position the reversing device promotes liquid to one of the two and / or both spray devices, and detecting the current position of the reversing device due to at least one operating parameter associated with the first drive.
- a dishwasher comprising a rinsing container, at least two sprayers arranged within the rinsing container, a circulation pump for conveying liquid to the spraying devices, a first drive for driving the circulating pump, a reversing device, due to the position of which the circulating pump liquid promotes to one of the two and / or both spray devices, and a control device for controlling and / or regulating the first drive.
- the control device is set up to detect the current position of the reversing device on the basis of at least one operating parameter assigned to the first drive.
- the dishwasher according to the invention has the washing container, within which the at least two spray devices are arranged.
- Spraying devices are, for example, well-known spray arms, to which, during operation of the dishwasher, the circulating pump is conveyed as part of a washing program of liquid, which is generally referred to as rinsing liquor.
- rinsing liquor As part of the washing program, it is normally provided during a program part, e.g. to provide only one of the two spray devices in particular alternately with the liquid. But it can also be provided to supply both spray devices with the liquid.
- the dishwasher comprises the reversing device, which is also referred to as a water diverter.
- Switching devices as such are e.g. known from DE 198 57 101 B4 mentioned in the introduction and are arranged between the circulation pump and the spray devices.
- a reversing device comprises e.g. a valve body, which can be adjusted, for example by means of a drive, in particular by means of an electric drive, so that liquid conveyed by the circulating pump reaches the desired spraying devices.
- the circulation pump is driven by the first drive, e.g. a first electric drive can be driven.
- the operating parameter may be an electric current, an electric voltage, an electric power, a torque and / or a rotational speed of the electric drive. Since, according to this variant, the circulation pump is driven by the first electric drive, operating parameters of the first electric drive, such as in particular the aforementioned electric current or the electric power of the first electric drive in response to the hydraulic load on the circulation pump change. Accordingly, it is possible to draw conclusions about the current position of the reversing device on the basis of these operating parameters.
- the first electric drive comprises e.g. a converter or inverter and an electric motor.
- the operating parameter assigned to the first electric drive is also used for controlling and / or regulating the first electric drive.
- no special device for determining the operating parameter is needed for the method according to the invention since this is already available for the regulation and / or control of the first drive driving the circulation pump.
- the reversing device may e.g. be adjusted by means of a second drive, in particular by means of a second electric drive.
- the control device of the dishwasher according to the invention can be set up in a relatively simple manner, to control the second electric drive.
- the control device comprises z. B. a suitably programmed microprocessor.
- the reversing device is adjusted until it is recognized on the basis of the at least one operating parameter that the reversing device has a desired position occupies.
- This embodiment can be achieved in particular relatively easily by a corresponding embodiment of the control device of the dishwasher according to the invention, which controls the second drive suitable due to the operating parameter.
- the at least one operating parameter is compared with the individual positions of the reversing device associated comparison values during the adjustment of the Um tenuvorraum to recognize the current position of the Um tenuvoroplasty due to the at least one operating parameter.
- the hydraulic load on the circulating pump and thus the operating parameters changes as a function of the position of the reversing device.
- the individual positions of the reversing device can accordingly be assigned corresponding hydraulic loads and therefore also corresponding values of the operating parameter.
- These values of the operating parameter are the comparison values, e.g. are stored in a memory of the dishwasher according to the invention.
- the control device of the dishwasher according to the invention is then configured, for example, to compare the current operating parameter with the comparison values and at the same time to adjust the reversing device until the current operating parameter assumes the value of the comparison value corresponding to the desired position of the reversing device.

- At least two spraying devices which in the case of the present embodiment are designed as upper and lower spray arms 5, 6, are arranged in the washing container 2 for impinging on the washware with a liquid, which is usually referred to as washing liquor.
- the liquid can be conveyed by a circulation pump 7 via a first liquid supply line 8 to the upper spray arm 5 and via a second liquid supply line 9 to the lower spray arm 6. This is illustrated in FIG. 2 by means of arrows 21-23.
- the liquid is heated, at least in a partial program step of a washing program of the dishwasher 1 by a water heater 10, which is connected to an inlet nozzle 1 1 to the circulation pump 7 and with outlet ports 12, 13 to the liquid supply lines 8, 9.
- the number of outlet ports 12, 13 corresponds to the number of spray arms 5, 6 or simultaneously operated groups of spray arms 5, 6.
- the funded by the circulation pump 7 liquid is therefore in the case of the present embodiment to the inlet nozzle 1 1 of the water heater 10 and the output nozzle 12, 13 via the liquid supply lines 8, 9 to the spray arms 5, 6 passed.
- the dishwasher 1 also has an electric drive 15, whose electric motor via a shaft 16, the circulation pump 7 drives.
- the electric drive 15 also has a converter or inverter, which supplies the electric motor of the electric drive 15 with electrical energy.
- the inverter generates the required three-phase electrical voltage for the motor, ie the required frequency and the required rms value of the electrical voltage.
- Suitable converters have, for example, power semiconductors and are generally known to the person skilled in the art, for which reason the converter is not explicitly shown and will not be explained further.
- the electric drive 15 is connected by means of an electrical line 17 to a control device 18 of the dishwasher 1, so that the control device 18 can control the converter or the electric drive 15 in a generally known manner and optionally also regulate.
- the control device 18 includes e.g. a suitably programmed microprocessor and is generally provided to control the dishwasher 1 so that it performs the washing program.
- the control device 18 Via the electrical line 17, the control device 18 also receives information about at least one operating parameter of the electric drive 15.
- the operating parameter of the electric drive 15 can be e.g. be used to control or regulate the electric drive 15.
- the operating parameter is the electrical power or the electrical power of the electric drive 15.
- the electric current of the electrical drive 15 is used to see the current position of a reversing device, in particular a water diverter 14, which is e.g. in the flow heater 10 is arranged or formed on this, to recognize.
- the water diverter 14 may e.g. but also be arranged in the dishwasher 1 by itself or be connected directly to the circulation pump 7.
- the spray arms 5, 6 are alternately and / or constantly charged with the liquid, which by opening a remplisstechniksauslasses and by closing another liquid outlet of the water switch 14th is achieved.
- the liquid outlets of the water distributor 14 pass directly into the outlet ports 12, 13 or are identical to these.
- the water distributor 14 has a liquid inlet, which in the case of the present exemplary embodiment adjoins or is formed by the inlet connection 11.
- a valve body is adjusted by a drive, in particular an electric drive 19.

- the current values are eg effective or maximum values.
- the hydraulic load on the circulation pump 7 is greatest when both spray arms 5, 6 are charged with the liquid, and smallest, when only the upper spray arm 5 is acted upon with liquid. Promotes the circulation pump 6 only liquid to the lower spray arm 6, then the hydraulic load on the circulation pump 7 between the hydraulic loads of the aforementioned positions of the water switch 14. Therefore, the electric current of the circulating pump 7 driving electric drive 15 at a position of the water switch 14 at the largest, in which the circulation pump 7 promotes liquid to two spray arms 5, 6, and at a position of the water distributor 14 at the smallest, in which the circulating pump 7 promotes liquid only to the upper spray arm 5.
- the electrical current of the electric drive 15 driving the circulation pump 7 has a current value between the above-mentioned current values at a position of the water distributor 14, in which the circulation pump 7 delivers liquid only to the lower spray arm 6.
- the electric drive 19 moves the valve body of the water switch 14, which is also referred to as passing through the water switch position.
- the control device 18 or a computer program running on the control device 18 compares the current values of the current electric current of the electric drive 15 driving the circulating pump 7 with the stored current values. Due to this comparison, the controller 18 recognizes when the water diverter 14 has assumed a desired position, i. whether the circulation pump 7 due to the current position of the water distributor 14 fluid to the spray arms 5, 6 promotes as intended.
- the electric current of the electric drive 15 is used for the circulation pump 7 for detecting the position of the water distributor 14.
- Other operating parameters of the electric drive 15 are also suitable.
- Other suitable operating parameters are, for example, the torque, an electrical Voltage of the electric drive 15, for example, the rms value of the electrical voltage generated by the inverter, or a rotational speed of the electric motor.
- the dishwasher 1 comprises two spray arms 5, 6, which are acted upon by means of the circulating pump 7 with liquid.
