A sieve-like textile fabric (12) is disposed in between the filtration beaker (2) and the lid (5). In order to guarantee secure operation and ensure a good retaining effect with respect to particles having a size of approximately 200 mu m at different filtration-material fill heights in the filtration beaker, the sieve-like textile fabric (12) has at least one formed part (13) protruding into the inner volume (Vi) of the lid (5), whereby air can be found on both sides of the part (14) of the textile fabric (12) which is located the furthermost away from the filtration beaker (2).
Abstract:
A method for determining a depletion of a filter cartridge (11) within a liquid filter system (8) comprises a configuration step performed by the liquid filter system (8) and an external electronic data processing device (9). An individual depletion threshold liquid quantity is determined with the external electronic data processing device (9), and the individual depletion threshold liquid quantity is transmitted to and stored within the comparison unit (13) of the liquid filter system (8) as updated data for the depletion threshold liquid quantity that is used for estimating the depletion of the filter cartridge (11).
Abstract:
A method of operating a water tap (1), in particular a hot water tap (1), comprises a dispensing step in which water is dispensed from the water tap (1). Initiation of the dispensing step requires several preceding steps, including an actuation of a first actuating element (5) and an actuation of a second actuating element (6). Within an actuation step, the actuation of a first actuating element (5) is detected by a control unit (14). The actuation step also comprises an unlocking step, in which, upon detection of the actuation of the first actuating element (5), an unlocking time window is started by the control unit (14). The actuation step also comprises an activating step in which the actuation of the second actuating element (6) activates a dispensing switch (13). The dispensing step is only initiated in case that the activating step is triggered within the unlocking time window.
Abstract:
The invention relates to a method for controlling a temperature of a liquid (3) in a liquid container (1) filled with at least a first predetermined amount (11) of the liquid (3) using a heating device (2). The temperature of the liquid (3) in the liquid container (1) is measured and controlled by adjusting the heat output of the heating device (2). If the liquid container (1) is filled with less than the first predetermined amount (11) of liquid (3) until the liquid container (1) is filled with a second predetermined amount (15) of the liquid (3), wherein the second predetermined amount (15) of the liquid (3) is equal to or greater than the first predetermined amount (11) of the liquid (3), cool liquid (13) is fed into the liquid container (1) from a liquid reservoir, the heating device (2) is permanently activated, and the temperature of the liquid (3) in the partially filled liquid container (1) is controlled by adjusting the cool liquid volume flow rate of the cool liquid (13) fed into the liquid container (1).
