WATER-CONDUCTING HOUSEHOLD APPLIANCE AND METHOD FOR OPERATING A WATER-CONDUCTING HOUSEHOLD APPLIANCE
A water-conducting household appliance having at least one water-conducting component; a hot water connection having a first feed valve to connect the household appliance to a hot water network and a first inlet line connecting the first feed valve to the at least one water-conducting component; and a cold water connection having a second feed valve to connect the household appliance to a cold water network and a second inlet line connecting the second feed valve to the at least one water-conducting component. A temperature measurement facility is disposed in the hot water connection and measures a temperature of hot water from the hot water network.
1 . A water-conducting household appliance, comprising:
at least one water-conducting component;
a hot water connection having a first feed valve to connect the household appliance to a hot water network and a first inlet line connecting the first feed valve to the at least one water-conducting component; and
a cold water connection having a second feed valve to connect the household appliance to a cold water network and a second inlet line connecting the second feed valve to the at least one water-conducting component;
wherein a first temperature measurement facility is disposed in the hot water connection, the first temperature measurement facility to measure a temperature of hot water from the hot water network.
2 . The household appliance of claim 1 , wherein the household appliance is one of a dishwasher and a washing machine.
3 . The household appliance of claim 1 , wherein the first temperature measurement facility is disposed in the first feed valve.
4 . The household appliance of claim 3 , wherein the first temperature measurement facility is integrated into the first feed valve.
5 . The household appliance of claim 1 , wherein the first temperature measurement facility is an NTC thermistor.
6 . The household appliance of claim 1 , further comprising a control facility connected to at least the second feed valve and the first temperature measurement facility to control operation of the household appliance, the control facility to control the second feed valve in order to control an intake of cold water from the cold water network, depending on the temperature measured by the first temperature measurement facility.
7 . The household appliance of claim 6 , wherein, depending on a current setting of the household appliance, the control facility is configured to control the second feed valve in order to control the intake of the cold water from the cold water network.
8 . The household appliance of claim 6 , wherein the control facility only opens the second feed valve for an inflow of the cold water if the temperature measured by the first temperature measurement facility exceeds a threshold value assigned to a current setting of the household appliance.
9 . The household appliance of claim 1 , further comprising a second temperature measurement facility disposed in the cold water connection, the second temperature measurement facility to measure a temperature of cold water from the cold water network.
10 . The household appliance of claim 9 , wherein the second temperature measurement facility at least one of is disposed in the second feed valve and comprises an NTC thermistor.
11 . The household appliance of claim 10 , wherein the second temperature measurement facility is integrated into the second feed valve.
12 . The household appliance of claim 9 , wherein, depending on the temperature measured by the second temperature measurement facility, a control facility is structured to activate the second feed valve in order to control an intake of the cold water from the cold water network.
13 . The household appliance of claim 1 , wherein at least one of the hot water connection and the cold water connection form a water stop system.
14 . A method for operating a household appliance, the method comprising:
measuring a water temperature of hot water supplied to the household appliance; and
setting an intake of cold water as a function of the measured water temperature of the hot water.
15 . The method of claim 14 , wherein the intake of the cold water is set as a function of a current setting of the household appliance.
16 . The method of claim 14 , wherein the cold water is supplied only if the measured water temperature of the hot water exceeds a threshold value assigned to a current setting of the household appliance.
17 . The method of claim 14 , further comprising:
measuring a water temperature of cold water supplied to the household appliance; and
setting the intake of the cold water as a function of the measured water temperature of the cold water.
