- commercial dishwashers should clean the dishes as quickly and hygienically as possible while consuming as little water and energy as possible. Therefore, a rinse cycle (rinse) of a commercial dishwasher usually lasts only very short (typically only a few minutes) and requires only small amounts of fresh water (typically only a few liters).

For particularly long rinse times or when using special rinsing chemistry, the temperatures of rinse water and fresh water may differ from the typical temperatures listed above beispielhalft, in particular lower.
- the electric radiators (or, where applicable, their individually controllable heating coils) of the boiler and the rinsing water tank, as well as the circulating pump represent the relevant power consumers in the dishwasher.
- These electrical load elements usually have a power consumption in the kW range, while other electrical loads, such as electrically operated metering pumps and solenoid valves, the power divider, the control electronics, electrical controls or a display, etc. only require currents in the single-digit or double-digit mA range and thus contribute only slightly to energy consumption.

- the measurement unit compares the phase angles of star voltages U L I N, U L2 - N and U L3 - N together. If the neutral conductor is not connected, it runs via a circuit in the measuring unit 303 in synchronism with one of the phases LI, L2 or L3. Via the phase position, the measuring unit 303 calculates whether it is a triangular network or star network.
- the configuration switching unit 302 can also be implemented "manually.”
- terminals are used manually during the installation of the dishwasher in order to configure the interconnection of the conductors LI according to the network type , L2, L3 and N.
- the conductors LI, L2, L3 and N must be connected by means of shorting terminals or bridges so that the (groups of) load elements are connected to the phases as shown in Fig. 6, i. the on-site (not existing) neutral is not used.
- the plug of the connection cable already correctly transmits the individual phases to the mains connection terminal of the dishwasher.
- the measuring device 303 can only be connected to the individual conductors LI, L2, L3 and N after this. Accordingly, in this case, the set bridges must be taken into account in detecting the type of mesh from the measuring device 303.

- the power controller 300 comprises instead of the configuration switching unit 302 and switching unit 304, a switching matrix with switches that allow each electrical load element depending on the detected low-voltage network (and its power provided) and depending on the process step of the rinse cycle with one of the conductors LI , L2 and L3 and the neutral (star network and single-phase AC mains) or to connect two of the conductors LI, L2 and L3 (delta network).
- the configuration of the power controller, and in particular the manner in which the configuration switching unit 302 and the switching unit 304 are switched by the processor unit 307 depends, as explained, both on the number and the individual powers of the considered load elements, as well as on the low-voltage network the dishwasher is connected (type of mains, voltage and protection).
- the invention is not limited to the number of consumer elements shown in FIG. 3, in particular to a 4-way boiler heater and a 1-coil tank heater.
- the boiler heater and tank heater may also have more or less heating coils (and thus consumer elements).

- a further aspect of the invention relates, as already mentioned, to an energy-saving operation of a (commercial) dishwasher, as has been described, for example, with reference to FIGS. 1 to 3.
- the dishwasher monitors in standby mode the temperature of water required in a rinse cycle provided by a tank or boiler of the dishwasher and ensures that the water temperature does not fall below a certain predetermined temperature.
- This temperature is chosen so that at the start of a rinse cycle (ie, the rinsing operation is taken and a rinse cycle to go through), the water during the rinse cycle with the desired (target) temperature, at the desired time and optionally in the desired amount (depending on the embodiment) can be provided to allow a hygienic rinsing operation.
- the dishwasher activates and deactivates the heating of the boiler and / or rinse water tank.
- the dishwasher allows that during the standby time of the dishwasher, the temperatures of at least the fresh water in the boiler and optionally also the rinsing water in the tank can be lowered and not fall below certain minimum temperatures.
- the predetermined temperature for the fresh water which should not be fallen below, so this is chosen so that in the case of starting a rinse the rinse cycle can be started immediately and completed in the desired time, but still a hygienic cleaning by rinsing with sufficient heated water (eg 85 ° C) is ensured.
- the predetermined temperature is selected so that the boiler can provide fresh water in the desired amount and at the desired temperature at the beginning of the post-rinse phase in the rinse cycle (or at least for a sufficient time within the rinse phase).
- the predetermined temperature which should not be undershot, chosen so that the The boiler heats the water in the boiler within 104 seconds to the desired temperature of 85 ° C.
- the boiler volume may be selected so that, irrespective of the rinse volume selected, the amount of residual water in the boiler after rinsing is constant (e.g., 4.5 liters).
- the value of the predetermined fresh water temperature depends, inter alia, on the power that can be made available to the radiator during the available time span (ie 104 sec in the preceding example). Among other things, this power may depend on the maximum power of the low voltage network (ie voltage, number of phases and their protection). Of course, also affects (as explained) the version svolumen the boiler and remaining in the boiler residual water, the performance of the boiler heater, or their coils, the amount of water required, as well as the time that is available for heating the fresh water is the predetermined temperature, which should not fall below. For a dishwasher, as described with reference to FIGS.
- the table below shows, for a selection of different powers of the low-voltage network, by way of example, which temperature of the fresh water should not fall below in standby mode, ie 2 or 3 liters
- Fresh water can be provided for the rinsing phase beginning at 104 seconds after the start of the cycle at 85 ° C.
- Table 3 below assumes that after rinsing, a residual water quantity of 4.5 l will always remain in the boiler. Accordingly, after refilling the boiler 6.5 1 and 7.5 1 fresh water in the boiler, which must be heated and then should not fall below the minimum temperatures shown in Table 3.
- the rinse water has a certain temperature, for example 62 ° C., for a certain time.
- a certain rinse water temperature can be set, which should not be undershot in standby mode, so that the rinse cycle can be started immediately and yet the rinse water is available at a desired time of the rinse cycle with the desired temperature.
- the recirculation time lasts 104 seconds.
- the certain rinse water temperature which should not be exceeded in the standby mode, can be selected so that at least for a certain time, for example 15, 30 seconds or 45 seconds of the circulation time, the rinse water (at least) a certain temperature, eg 62 ° C, owns.
- a certain temperature eg 62 ° C
- Table 3 it is possible to use different types of low - voltage networks (and optionally for different amounts of flushing water) determine the respective minimum flushing water temperatures, which should not be undershot in standby mode.
- the fresh water is often supplied at a temperature below the designated minimum temperature of the fresh water in the boiler. If the grid connection power is low, it may happen that the temperatures required by the user for rinsing can not always be reached at the desired time when the next rinse cycle is started immediately after a rinse cycle has ended. In such a case, the dishwasher may correspondingly extend the rinse cycle or one or more process steps in which a desired temperature is to be achieved until the desired temperatures are reached.
- the energy management and the temperature control of the dishwasher can be taken over either by the processor unit 307 of the power controller 300 or by the control unit of the dishwasher. If the control unit is used, it transmits the necessary control information via data bus to the power controller, or its processor unit 307, which assumes the control of the switching unit 304 accordingly. 3, a bus connection 306 is indicated, which enables communication between the processor unit 307 and the control unit (compare FIGS. 1 and 2). As discussed in connection with Table 2, for a given low voltage network in the individual process times of the purge cycle (eg recirculation phase and post rinse phase) there may be different combinations in which the consumer elements of the dishwasher can be operated without the maximum power provided by the low voltage network ( if necessary minus a safety margin).
- a hygienic rinse is to be achieved by rinsing with clear water, it makes sense to prioritize the boiler heater in the power supply to the tank heater. So it can be ensured that a rinsing cycle the fresh water for rinsing in the desired amount, with the desired temperature and at the desired time in the rinse cycle is provided by the boiler.
- the hygienic rinsing is to be made possible by a sufficiently high temperature of the rinsing water, then again it makes sense to prioritize the tank heating in the supply of power to the boiler heater. This ensures that in a rinse cycle the rinse water of the rinse water tank with the desired temperature and at the desired time in the rinse cycle from the rinse water tank is provided for rinsing the items to be cleaned.
