Embodiment one:
Firstly, a tap water faucet is opened, tap water enters a water storage tank of the solar water heater along a water delivery pipe 11 and a first water inlet pipe 8, and after the water storage tank is full of water, the first water inlet pipe 8 is closed by an automatic closing mechanism. The solar water heater then uses solar energy to heat. When hot water is to be used, the water pump 4 pumps the water from the water storage tank, and the hot water flows into the water delivery pipe 11 along the first water outlet pipe 9. At this time, the first temperature sensor 7 transmits the water temperature information in the first water outlet pipe 9 to the PLC, and the PLC judges whether the water temperature reaches the standard. When the water temperature reaches the height and is higher than the set temperature, the PLC controls the on-off state of the electric three-way valve II 6, so that hot water directly flows into the hot water pipe 12 and is used by a user through the shower head 1. If the first temperature sensor 7 senses that the water temperature in the first water outlet pipe 9 is lower than the set temperature, the second electric three-way valve 6 leads water into the electric water heater 2 through the second water inlet pipe 14 to heat, and then the hot water flows into the sprinkler 1 through the second water outlet pipe 13 and the hot water pipe 12. Therefore, the switching between the electric water heater 2 and the solar water heater 3 can be fully utilized, so that the purposes of saving energy and using hot water without being influenced by weather are achieved. If the solar water heater 3 fails, the PLC automatically switches the pipeline to allow tap water to directly enter the electric water heater 2.
When the second temperature sensor 18 senses that the outdoor temperature is lower than the set temperature, the PLC controls the water pump 4, the first electric three-way valve 5 and the second electric three-way valve 6 to start, so that water forms a circulating flowing loop among the solar water heater 3, the first water inlet pipe 8, the first water outlet pipe 9 and the water delivery pipe 11, and the water is kept flowing in the loop under the condition that the water storage tank of the solar water heater 3 is not full, so that the pipeline freezing pipe is prevented from being broken. And the water of the circulation loop can reach the water inlet of the electric water heater 2 quickly. The automatic antifreezing water circulation is set to be at a starting temperature of 0 ℃ and a stopping temperature of 5 ℃.
Embodiment two:
The electric three-way valve I5 enables the water outlet pipe I9 and the water delivery pipe 11 to maintain a communicating state, and the electric three-way valve III 16 and the water flow switch I15 are opened, so that water enters the water inlet pipe I8 from the tap water inlet pipe I10, and water is delivered to the water storage tank of the solar water heater 3. The automatic closing valve 17 automatically closes the water flow after the water storage tank is full, the water flow switch I15 transmits a water stopping signal to the PLC, the PLC controls the electric three-way valve I5 to conduct the water outlet pipe I9 and the water conveying pipe 11, controls the electric three-way valve III 16 to conduct the water inlet pipe I8 and the pressure relief pipe 22, the water pump 4 is in a stop working state, the pressure relief pipe 22 is automatically closed after a few seconds, and the water conveying system is restored at the moment. The water is circulated for a few minutes before water is used, the water pump 4 is started, the electric three-way valve III 16 is linked, and the water outlet pipe I9 circularly flows to the water inlet pipe I8. When the water heater is used, the water flows from the first water outlet pipe 9 to the hot water pipe 12, when the temperature sensed by the first temperature sensor 7 is higher than the set temperature, the second electric three-way valve 6 can enable the water flow to directly enter the hot water pipe 12 from the water pipe 11, the electric water heater 2 is automatically turned off for use, the water flow switch 19 senses that the water in the water pipe 11 flows, and the PLC can start the water pump 4 to start working.
