Definitions
- WO2018226706A1 describes a heating device that can be connected to water-carrying electrical devices in order to provide hot water.
- the heating device is designed as a flow heater and has a reservoir, a cold water connection, an inlet and outlet, a pump and a hot water return.
- this system is complex and requires a lot of space.
- the invention therefore addresses the problem of providing a method for operating a water-carrying electrical device and a water-carrying electrical device that are simple and require little installation space.
- the advantages that can be achieved with the invention consist in the fact that standardized conditions for operating the electrochemical cell are provided.
- the standardized conditions are achieved by adjusting the conductance of the liquid in the electrochemical cell to the predetermined conductance.
- the invention relates to a method for operating a water-bearing electrical device with a water intake element, an electrochemical cell, a Dosing device for dosing a detergent and/or cleaning agent containing a conductivity indicator into the electrochemical cell, comprising a) conducting water into the electrochemical cell; b) Dosing the washing and/or cleaning agent containing the conductivity sensor into the electrochemical cell or into the water flowing through it; c) determining a conductance of the liquid located in the electrochemical cell following steps a) and b); and d) setting the determined conductance to a predetermined conductance.
- the determined conductance can be set in a simple manner to the predetermined conductance value of the liquid in the electrochemical cell.
- the liquid is preferably conducted from the electric cell into the water absorption element and from there again into the electric cell, so that it is circulated through the electric cell and the water absorption element.
- the liquid is circulated from a first region of the water receiving member through the electrochemical cell to a second region of the water receiving member. This further improves the washing and/or cleaning performance of the liquid.
- Steps c) and d) are preferably carried out during the heating of the liquid in the electrochemical cell. This ensures that the electrochemical cell is operated under constant conditions during heating.
- the invention also relates to a water-carrying electrical device, having a water intake element, an electrochemical cell, a metering device that is designed to meter a detergent and/or cleaning agent containing a conductor into the electrochemical cell or into the water flowing through it, and a control unit that is configured to use a method according to one or more of the preceding to carry out described embodiments.
- the electrochemical cell has electrodes in the form of an anode and a cathode to which a voltage can be applied.
- the electrochemical cell is preferably designed to heat the liquid located in it when an AC voltage is applied to the anode and the cathode.
- the water-carrying electrical device is preferably designed as a washing machine or dishwasher.
- the device preferably also has a flooding system which is designed to convey water from a first area of the water holding element through the electrochemical cell into a second area of the water holding element.
- FIG. 1 shows a partial flow chart of a method according to the invention.
- the method is carried out in a water-carrying electrical device which has an electrochemical cell into which water is conducted and a washing and/or cleaning agent containing a conductivity sensor is metered in, so that there is a liquid in the electrochemical cell.
- a conductivity of the liquid located in the electrochemical cell is determined from water and detergent and/or cleaning agent containing a conductivity sensor.
- Step 2 is then carried out, in which the determined conductance is compared with a predetermined conductance.
