Abstract
Dispensing of hot water having an adjustable temperature by way of a water outlet fitting that can be installed on a sink. This is achieved by a continuous flow heater and a measured value sensor arranged in a water inlet of the water outlet fitting as the hot water heater. The measured value sensor detects a measurement variable with regard to water flowing through the continuous flow heater (10). The water dispensing device has a control unit, which is designed to regulate a flow rate through the continuous flow heater as a function of measured values of the measured value sensor in order to adjust the temperature of the hot water.
Claims14
A water-dispensing device for dispensing hot water, the water-dispensing device comprising:
- a water outflow fixture (20) which is configured to be installed on a sink (25),
- a hot water preparation device arranged in a water inflow (30) of the water outflow fixture (20), the hot water preparation device comprises a continuous flow heater (10),
- at least one measurement transducer arranged in the water inflow (30) of the water outflow fixture (20), which determines a measurement variable with respect to water flowing through the continuous flow heater (10),
- a water pump (11) arranged in the water inflow (30) of the water outflow fixture (20) on the inflow side of the continuous flow heater (10),
- a controller (50) configured to regulate, in a manner dependent on measurement values of the measurement transducer (12), a throughflow rate of water through the continuous flow heater (10) in order to set the temperature of the hot water delivered to a hot water line (22) in a definable temperature range, and the controller (50) is further configured to regulate a pump power of the water pump (11) in order to vary the throughflow rate in a continuously adjustable manner such that if an increase in the temperature of the hot water from the hot water line is required, the throughflow rate is reduced, and if a reduction in the temperature of the hot water from the hot water line is required, the throughflow rate is increased.
