The water heater 1 is a gas water heater, the control system 2 is a main controller arranged on the water heater, and the temperature sensing element 3 is a temperature sensor. In other embodiments, the water heater is an electric water heater, a solar water heater or a heat pump water heater, and the control system is a controller independent from the main controller, and is not limited to this embodiment.

The working principle of the water outlet control system provided by the embodiment is as follows, when the water outlet device 4 is opened, hot water flows out through the water heater 1, enters the water inlet pipe 8 of the water outlet device 4 and enters the rear cavity 6 of the shower head all the time. When the water temperature detected by the temperature sensing element 3 is less than the set water temperature, the control system 2 controls the second valve 10 to open, the first valve 7 to close, and water flows into the water return pipe 9 through the second valve 10 and then enters the water heater 1 through the cold water inlet pipe to continue heating, as shown in fig. 2. When the temperature detected by the temperature sensing element 3 is greater than or equal to the set temperature, the control system 2 controls the first valve 7 to open, the second valve 10 to close, and water flows into the front cavity 5 of the shower head through the first valve 7 for the user to use, as shown in fig. 3. Therefore, the user can be helped to realize the experience of hot water when the water bottle is opened, and the waste of water resources is reduced.

Example two
