1. A hot water supplying apparatus comprising:
a water heater that heats direct water to form hot water, comprising a heat exchanger and a flow rate detection unit;
a faucet;
a first direct water pipe supplying direct water;
a second direct water pipe connected between the heat exchanger and the first direct water pipe to supply the direct water from the first direct water pipe to the heat exchanger;
a hot water pipe connected between the heat exchanger and the faucet to supply the hot water from the heat exchanger to the faucet;
a third direct water pipe connected between the faucet and the first direct water pipe to supply the direct water from the first direct water pipe to the faucet; and
a controller comprising a function executing part,
wherein,
the flow rate detection unit is located in the second direct water pipe, and thea flow rate detection unit is configured to detect a flow rate change and a flow rate change pattern of the flow rate change, and to output a flow rate signal in the flow rate change pattern, and the flow rate change pattern is detected from the direct water flowing through the second direct water pipe and
the flow rate change pattern is a pattern of the flow rate change measured over time in seconds while a user closes and opens the faucet multiple times,
the flow rate change pattern shows that the flow rate signal changes ON or OFF with a duration when the faucet is open or closed, respectively,
the controller is configured to determine whether the flow rate change pattern generated by the user matches a preset specific pattern corresponding to a preset hot water control function, and the function executing part is configured to execute the preset hot water control function when the flow rate change pattern matches the preset specific pattern, such that the user executes the preset hot water control function by opening and closing the faucet to create the flow rate change pattern.
