Abstract
A method of controlling a drinking water supply device includes inputting a water discharge signal through an input lever, opening a first valve such that drinking water flows through a first channel and measuring the amount of drinking water flowing through the first channel using a flow rate sensor, opening a second valve for a predetermined time to discharge minerals when the amount of drinking water measured by the flow rate sensor reaches a first predetermined amount, and, opening the second valve again for the predetermined time to further discharge minerals when a second predetermined amount of drinking water is measured by the flow rate sensor.
Claims13
A method of controlling a drinking water supply device, the method comprising:
- receiving a water discharge signal;
- opening a first valve such that water flows through a first channel;
- sensing a flow rate to determine an amount of water flowing through the first channel;
- opening a second valve to discharge minerals to be combined with the water when the amount of water reaches a first predetermined amount;
- closing the second valve after a first predetermined amount of time while the first valve is open;
- reopening the second valve to discharge minerals to be combined with the water when the amount of water reaches a second predetermined amount;
- and
- closing the second valve after a second predetermined amount of time.
A drinking water supply device comprising:
- a first channel through which water flows, the first channel including a first valve that opens and closes the first channel and a flow rate sensor that senses a flow rate of the drinking water trough the first channel;
- a water discharge channel connected downstream of the first channel and configured to discharge the water;
- a connection pipe that connects the first channel to the water discharge channel;
- a second channel through which minerals are supplied to the connection pipe, the second channel including a second valve that opens and closes the second channel;
- a mineral container connected to the second channel and provided upstream of the second valve to receive condensed minerals;
- an input configured to generate a water discharge signal when the input is activated and configured to generate a water discharge end signal when the input is deactivated;
- and
- a controller configured to open the second valve for a first predetermined time to discharge minerals upon receiving the water discharge signal and determining that an amount of water has reached a first predetermined amount.
