Claims (10)
- A method for controlling a washer (1) comprising a cold water intake (2) and a hot water intake (3), a first valve (4) for opening/closing the cold water intake (2), a second valve (5) for opening/closing the hot water intake (3), a control unit (6) for individually controlling the first valve (4) and the second valve (5), a third valve (7) for homogenously mixing the cold water which is output by the first valve (4) and the hot water which is output by the second valve (5), a washing chamber (8) for collecting the mixed water which is output by the third valve (7) and a temperature sensor (9, 9´, 9´´) for measuring a temperature T_mix of the mixed water, wherein the temperature sensor (9, 9´, 9´´) is arranged on a downstream side of third valve (7), the method being characterized by comprisinga step of controlling the first valve (4) and the second valve (5) based on the temperature T_mix and a target temperature T_target of the mixed water.
- The method according to claim 1, characterized in that the controlling step includesa step (S1) of opening both the first valve (4) and the second valve (5),a step (S2) of measuring T_mix by using the temperature sensor (9, 9´, 9´´),a step (S5, S7) of comparing T_mix with T_target,a step (S6) of closing the second valve (5) while keeping the first valve open (4) if T_mix is larger than T_target anda step (S8) of closing the first valve (4) while keeping the second valve (5) open if T_mix is smaller than T_target.
- The method according to claim 1 or 2, characterized in that the controlling step includes a step (S4) of determining T_target.
- The method according to claim 3, characterized in that in the determining step (S4) T_target is determined based on a currently selected washing program, wherein T_target is a value predetermined for each washing program.
- The method according to claim 3, characterized in that in the determining step (4) the T_target is determined based on a temperature of the cold water received through the cold water intake (2) and a temperature of the hot water received from the hot water intake (3).
- The method according to any one of claims 1 to 5, characterized in that the controlling step includes a step (S3) of closing both the first valve (4) and the second valve (5) if a fill level of the washing chamber (8) is reached.
- A washer (1), in particular a dishwasher, comprising- a cold water intake (2) and a hot water intake (3),- a first valve (4) for opening/closing the cold water intake (2),- a second valve (5) for opening/closing the hot water intake (3) and- a control unit (6) for individually controlling the first valve (4) and the second valve (5),the washer (1) being characterized by further comprising-a third valve (7) for homogenously mixing the cold water which is output by the first valve (4) and the hot water which is output by the second valve (5),- a washing chamber (8) for collecting the mixed water which is output by the third valve (7) and- a temperature sensor (9, 9´, 9´´) for measuring a temperature T_mix of the mixed water, the temperature sensor (9, 9´, 9´´) being arranged on a downstream side of the third valve (7), wherein the control unit (6) is configured to execute the method steps defined in any one of claims 1 to 6.
- The washer (1) according to claim 7, characterized in that the temperature sensor (9) is arranged to measure the temperature T_mix of the mixed water immediately at an output side of the third valve (7).
- The washer (1) according to claim 7, characterized by further comprising an auxiliary chamber (10) which is arranged on a downstream side of the the third valve (7) and on an upstream side of the washing chamber (8), wherein the temperature sensor (9´) is arranged to measure the temperature T_mix of the mixed water inside the auxiliary chamber (10).
- The washer (1) according to claim 7, characterized in that the temperature sensor (9´´) is arranged to measure the temperature T_mix of the mixed water inside the washing chamber (8).
