The operation principle of a kind of solar water heater control device that can mutually switch with other water heater of the present invention is as follows: shown in Figure 3, during use, at first can be by the water level in the preset setting solar water heater water tank 17 of controller 10 and water temperature (usually being set as 55 degree), by the preset setting return water temperature of controller 10 (usually being set as 35 degree), by the preset setting of controller 10 hot water effluent temperature (usually being set as 46 degree), controller 10 shows water level and water temperature after receiving the signal that water-temperature water-level sensor 14 brings.
Water level in water tank 17 during lower than the water level set, can be selected two kinds of water feeding modes, and a kind of water feeding mode is: controller 10 output control signals are opened water solenoid valve 9, upper water just by cold water watering pipeline 3 through water return pipeline 4 to the interior water inlet of water tank 17; When water-temperature water-level sensor 14 detects water level in water tank 17 in a high position, after controller 10 receives the signal that water-temperature water-level sensor 14 brings, the output control signal is closed and is closed water solenoid valve 9, just stops to the interior water inlet of water tank 17.Another kind of water feeding mode is: the water level in water tank 17 is during lower than the water level set, and controller 10 output control signals are opened branch's magnetic valve 18, upper water just by cold water watering pipeline 3 through hot water line 2 to the interior water inlet of water tank 17; When water-temperature water-level sensor 14 detects water level in water tank 17 in a high position, after controller 10 receives the signal that water-temperature water-level sensor 14 brings, output control signal close fork magnetic valve 18, just stop to the interior water inlet of water tank 17.
When sunny, water temperature in water tank 17 generally is not less than the temperature of setting, during use, fetch boiling water leading 12, after there are flowing out, tap 12 at once tap 12 is closed, now, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, the output control signal starts water pump 6 work, export control signal simultaneously and open backwater motor-driven valve 8, make hot water line 2 and water return pipeline 4 form circulation waterway, allow hot water line's 2 interior cold water be circulated back to as early as possible in water tank 17, in this process, the temperature of measuring when return water temperature sensor 5 is higher than the return water temperature of setting, controller 10 switches off the pump 6 and backwater motor-driven valve 8, water stops circulation.Now, then the tap 12 of fetching boiling water, just can normally use hot water.
When sunlight is inadequate, water temperature in water tank 17 can be lower than the temperature of setting, now can select two kinds of occupation modes, a kind of: during use, fetch boiling water leading 12, after there are flowing out, tap 12 at once tap 12 is closed, now, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, the output control signal starts water pump 6 work, export control signal simultaneously and open backwater motor-driven valve 8, close and often open hot water electromagnetic valve 13, open normally closed hot water electromagnetic valve 16, then start other water heater 32, allow hot water line's 2 interior cold water first be circulated back in water tank 17, when the temperature of measuring when return water temperature sensor 5 is consistent with the water temperature in water tank 17, controller 10 switches off the pump 6 and backwater motor-driven valve 8, water stops circulation.Now, fetch boiling water again leading 12, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, the output control signal starts water pump 6 work (or also can not start water pump 6 when pressure does not enough need to pressurize), close and often open hot water electromagnetic valve 13, open normally closed hot water electromagnetic valve 16, cold water becomes hot water after other water heater 32 heating, just can normally use hot water.Another kind of occupation mode is: when sunlight is inadequate, water temperature in water tank 17 can be lower than the temperature of setting, during use, first start electrical heating 19, temperature in heating water tank 17 is to 55 ℃ of the temperature of setting, then fetch boiling water leading 12, after there are flowing out, tap 12 at once tap 12 is closed, now, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, the output control signal starts water pump 6 work, export control signal simultaneously and open backwater motor-driven valve 8, allow hot water line's 2 interior cold water first be circulated back in water tank 17, the temperature of measuring when return water temperature sensor 5 is during higher than the return water temperature set, controller 10 switches off the pump 6 and backwater motor-driven valve 8, water stops circulation.Now, fetch boiling water again leading 12, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, the output control signal starts water pump 6 work (or also can not start water pump 6 when pressure does not enough need to pressurize), just can normally use hot water.In addition, in cold winter, in order to prevent water tank 17, be damaged by frost, also can start electrical heating 19 when needed, suitably the water in heating water tank 17.
A kind of solar water heater control device that can mutually switch with other water heater of the present invention can be controlled the switching of solar water heater and other water heater automatically, simple, convenient, reliable.
