Description
Technical Field
The application relates to a method of operating a water-bearing electrical installation and to a water-bearing electrical installation.
Background
WO2018226706A1 describes a heating device which can be connected to a water-bearing electrical apparatus to provide hot water. The heating device is designed as a continuous heater and has a water reservoir, a cold water connection, an inlet and an outlet, a pump and a hot water return. However, this system is complicated and requires a large installation space.
Disclosure of Invention
The problem faced by the present application is therefore to provide a method of operating a water-bearing electrical installation and a water-bearing electrical installation which are simple and require a small installation space.
According to the application, this problem is solved by a method having the features of claim 1 and a water-bearing electrical installation having the features of claim 9. Preferred embodiments and further developments of the application can be found in the following dependent claims.
The advantages achievable by the present application, in addition to reducing the complexity of the system and the installation space, provide standardized conditions for operating the electrochemical cell. The standardized conditions are achieved by adjusting the conductivity of the liquid in the electrochemical cell to a preset conductivity.
Since water has different conductivities depending on the region, heating the water generally has to be performed with different parameters. This results in an increase in design effort, such as the electrode surface and control effort required to compensate for this. The present application solves this problem by adjusting the conductivity of the liquid in the electrochemical cell to a preset conductivity, thereby eliminating or at least minimizing the design and control effort, as the electrochemical cell can always be operated under the same conditions. The water-carrying electric equipment is compact in design.
The application relates to a method for operating a water-bearing electrical installation having a water receiving device, an electrochemical cell, a metering unit for metering a washing and/or cleaning agent containing an electrically conductive component into the electrochemical cell, the method having:
a) Introducing water into the electrochemical cell;
b) Metering a detergent and/or cleaning agent containing an electrically conductive component into an electrochemical cell or into water flowing through the electrochemical cell;
c) Determining the conductivity of the liquid in the electrochemical cell after steps a) and b);
d) The determined conductivity is adjusted to a preset conductivity.
The power required to heat the liquid depends on the conductivity of the liquid to be heated. By adjusting the conductivity to a preset conductivity by the liquid produced by the supply of water or a detergent and/or cleaning agent containing an electrically conductive component, the electrochemical cell can be operated under the same conditions, regardless of the conductivity of the water supplied to the electrochemical cell or the conductivity of the detergent and/or cleaning agent. The device is particularly advantageous in areas of low water hardness and thus having low water conductivity values.
Preferably, drinking water is supplied to the electrochemical cell T in step a). The conductivity of drinking water varies from region to region.
In a preferred embodiment, step d) comprises
-comparing the preset conductivity with the determined conductivity; and
-introducing water into the electrochemical cell when the determined conductivity is greater than the preset conductivity, and introducing a detergent and/or cleaning agent containing an electrically conductive component into the electrochemical cell when the determined conductivity is less than the preset conductivity.
This means that the determined conductivity of the liquid located in the electrochemical cell can be easily adjusted to a preset conductivity.
Preferably, step c) comprises applying a preset voltage to the electrochemical cell, measuring the current in the electrochemical cell, and determining said conductivity based on the measured current. In this way the conductivity of the liquid in the electrochemical cell can be easily determined.
Preferably, the electrochemical cell is designed for the following operating ranges: above the conductivity present when the water hardness is above 14 deg. dH, or preferably above 17 deg. dH, even more preferably above 21 deg. dH. The preset electrical conductivity is preferably stored in the water-bearing electrical installation.
In a preferred embodiment, when the determined conductivity is equal to the preset conductivity, the electrochemical cell is activated such that the liquid therein is heated. For example, the electrochemical cell is started by applying an AC voltage to the electrodes of the electrochemical cell. Preferably, the liquid is led from the electrochemical cell into the water receiving means during and/or after heating. So that the liquid can wash and/or clean the water-receiving device and/or the objects located therein.
Preferably, liquid is directed from the electrochemical cell into the water receiving means and from the water receiving means back into the electrochemical cell such that liquid circulates through the electrochemical cell and the water receiving means. In a preferred embodiment, liquid is circulated from a first region of the water receiving means through the electrochemical cell to a second region of the water receiving means during and/or after heating the liquid in the electrochemical cell. This further improves the washing and/or cleaning performance of the liquid.
Preferably, steps c) and d) are performed during heating of the liquid in the electrochemical cell. This ensures that the electrochemical cell operates under constant conditions during heating.
In a preferred embodiment, the conductive component is selected from the group consisting of a base carrier, an inorganic or organic acid, an organic acid salt, a phosphonate, a surfactant and/or mixtures thereof. The conductive component may form part of a detergent and/or cleaning agent which may further comprise a washing and/or cleaning active. The washing and/or cleaning agent may also consist of the conductive component. The conductivity resulting from the conductive component is higher than the conductivity of water that can be used to dilute the detergent and/or cleaner containing the conductive component.
The application also relates to a water-bearing electrical installation having
-a water receiving device
Electrochemical cell
A metering unit designed to meter a detergent and/or a cleaning agent containing an electrically conductive component into the electrochemical cell or into water flowing through the electrochemical cell,
-a control unit designed to perform the method of one or more of the foregoing embodiments.

Preferably, the water-bearing electrical device is designed as a washing machine or dishwasher.
Preferably, the apparatus further has a circulation system designed to transport water from a first region of the water receiving means to a second region of the water receiving means through the electrochemical cell.

fig. 1 shows a partial flow chart of the method according to the application.
Detailed Description
Fig. 1 shows a partial flow chart of the method according to the application. The method is carried out in a water-bearing electrical apparatus having an electrochemical cell into which water is introduced and into which a washing and/or cleaning agent containing an electrically conductive component is metered such that a liquid is present in the electrochemical cell. In step 1, the conductivity value of the liquid present in the electrochemical cell is determined from water and a detergent and/or cleaning agent containing an electrically conductive component. Subsequently, step 2 is performed, wherein the determined conductivity is compared with a preset conductivity.
In step 3, if the determined conductivity is greater than the preset conductivity, water is introduced into the electrochemical cell to adjust the conductivity of the liquid to the preset conductivity. In step 5, if the determined conductivity is equal to the preset conductivity, the electrochemical cell is put into operation in step 6, so that the liquid inside the electrochemical cell is heated. In step 7, if the determined conductivity is less than the preset conductivity, a detergent and/or cleaning agent containing an electrically conductive component is metered into the electrochemical cell in step 8 to adjust the conductivity of the liquid to the preset conductivity. After steps 4, 6 and 8, step 1 may still be performed again.
