The heater 2 is arranged in the water storage 1 for heating the water in the water storage 1 . The water inlet pipe 3 includes a cold water inlet pipe 301 and a hot water inlet pipe 302 , and the cold water inlet pipe 301 and the hot water inlet pipe 302 are respectively connected to the water storage 1 . The mixing valve 4 has a cold water inlet 401 connected to the cold water inlet pipe 301 , a hot water inlet 402 connected to the hot water inlet pipe 302 , a water outlet 403 and a valve core 404 . The water outlet pipe 5 is connected to the water outlet 403 of the water mixing valve 4 . The motor 6 is connected to the spool 404 . The temperature collector 7 is arranged at the water outlet 403 of the water mixing valve 4 and the water storage 1 , and collects the water temperature signal at the water outlet 403 and the water temperature signal in the water storage 1 . The controller 8 is electrically connected to the temperature collector 7 , the motor 6 and the heater 2 respectively. The controller 8 receives the water temperature signal collected by the temperature collector 7 and sends a control signal to control the motor 6 and the heater 2 according to the water temperature signal. In this embodiment, the type of the motor 6 is a servo motor, and the servo motor has a large enough self-locking force to keep the position of the valve core 404 fixed when the water flow rate and water pressure are high, thereby ensuring a constant outlet water temperature. The model of the temperature collector 7 is DS18B20, which has a high resolution of 0.5 degrees, and can directly read the temperature value, and has the characteristics of low cost and easy use. The model of the controller 8 is AT89C52. However, the present utility model does not make any limitation thereto.

Specifically, the user presets the hot water temperature of the water storage 1 and the water outlet 403 through the voltage dividing circuit in the controller 8 . Start the heater 2 to heat the cold water in the water storage tank 1 . The temperature collector 7 collects the water temperature in the water storage 1 in real time and transmits the collected water temperature signal to the controller 8 . When the water temperature reaches the set value, the controller 8 sends a control signal to turn off the heater 2 . At this time, the user can use the hot water in the water storage device 1 . During the user's use, the cold water inlet pipe 301 supplies cold water to the water storage 1, and the supplemented cold water generates pressure, so that the hot water in the water storage 1 flows to the water mixing valve through the hot water inlet pipe 302 and the hot water inlet 402 4 within. At the same time, the cold water inlet pipe 301 delivers cold water to the water mixing valve 4 through the cold water inlet 401 , and the cold water and hot water are mixed and flow out through the water outlet 403 . The temperature collector 7 at the water outlet 403 collects the water temperature signal of the outlet water in real time and transmits the water temperature signal to the controller 8 . The controller 8 compares the water temperature signal with a set value. When the collected outlet water temperature is greater than the user's set value, the controller 8 sends a control signal to the motor 6 . The motor 6 drives the spool 404 in the water mixing valve 4 to rotate, so that the opening of the hot water inlet 402 decreases, the opening of the cold water inlet 401 increases, and the temperature of the outlet water gradually drops to a user-set value. Similarly, when the collected outlet water temperature is lower than the user's set value, the controller 8 sends a control signal to the motor 6 . The motor 6 drives the spool 404 in the water mixing valve 4 to rotate, so that the opening of the hot water inlet 402 increases, the opening of the cold water inlet 401 decreases, and the outlet water temperature gradually rises to the user's set value. When the collected outlet water temperature is equal to the user's set value, the motor 6 stops, and the position of the spool 404 is fixed. The temperature collector 7, the controller 8 and the motor 6 continuously repeat the above process to ensure that the water temperature of the water outlet 403 is constant on the user's set value.

The controller 8 continuously collects the time signal of the timer 10, and compares it with the time generated by its own crystal oscillator. When the two are equal, the controller 8 sends a control signal to change the switch state of the heater 2 to realize the function of timing automatic switch. The on-off time of timer 10 can be set when the user goes out. When the time arrives, the water heater outlet device can turn on the heater 2 automatically. Not only is it convenient for users to use hot water at any time, but it can also avoid peak hours of electricity consumption, which can save a lot of electricity costs. In this embodiment, the model of the timer 10 is DS1302. However, the present utility model does not make any limitation thereto.

Specifically, when initially heating, the temperature collector 7 collects the water temperature in the water storage 1 is low, the controller 8 outputs a positive high-frequency signal, the bidirectional thyristor is fully turned on, and the heating power of the heater 2 increases . As the difference between the collected temperature and the set temperature gradually decreases, the frequency of the positive signal output by the controller 8 decreases, the bidirectional thyristor is partially turned on, and the heating power of the heater 2 decreases. When the collected temperature is equal to the set temperature, the controller 8 outputs a negative signal, the bidirectional thyristor is cut off, and the heater 2 does not heat. The photoelectric isolator can isolate the digital signal and the analog signal, and improve the accuracy and anti-interference ability of the water heater outlet device.
