The course of work of present embodiment is as follows:
(1) first temperature sensor 4 in being contained in solar thermal collector 1 be contained in second sensor, 18 measured temperatures in the storage tank 39 when differing 10 ℃, auto-controller starts thermal-arrest circulating pump 3 automatically; When the temperature balance of the temperature of the water in the solar thermal collector and the water in the storage tank 39, auto-controller stops the work of thermal-arrest circulating pump 3.
When the temperature that records when first temperature sensor 4 was 5 ℃, auto-controller started thermal-arrest circulating pump 3 and carries out antifreeze circulation.
When first temperature sensor 4 recorded temperature and is higher than 85 ℃, auto-controller sent the buzzing alarm signal.
(2) level sensor 42 is high water level control sensor, and when the water level in the storage tank 39 reached the position of level sensor 42, auto-controller was closed normally open solenoid valve 40, thereby stops to go up water.
(3) when the user opens check valve 33 and uses hot water, water flow switch starts hot water circulating pump 35 work, and when the temperature that the 5th temperature sensor 36 on being installed in hot water circulating pipeline 22 records reached 38 ℃, auto-controller stopped the work of hot water circulating pump 35; When the temperature that records when the 6th temperature sensor 23 was lower than 5 ℃, auto-controller started hot water circulating pump 35 work, carries out antifreeze circulation.
(4) when three-temperature sensor 19 records water temperature in the storage tank and is lower than 37 ℃, auto-controller is according to the concrete size of water temperature, control pipeline electromagnetic heater 37 enters 1 grade, 2 grades, 3 grades readiness, when the user opened check valve 33 waters, water flow switch started 37 work of pipeline electromagnetic heater.

(7) process of fetching water of the constant temperature water layer in the motion tracking storage tank:
At first setting the upper and lower limit temperature of constant temperature water layer, is the bottom that enters storage tank 39 from upper hose 38 because cold water replenishes, so in storage tank 39, the water temperature on upper strata is higher than lower floor.If the capping water temperature is 40.8 ℃, the lower limit water temperature is 39.2 ℃, so, the water inlet of water intaking flexible pipe 16 should be immersed in automatically under the control of auto-controller and lifting follower in the water temperature layer of 39.2≤T≤40.8 ℃ and fetch water, and its detailed process is as follows:
When the 4th temperature sensor 20 records water temperature and is higher than 40.8 ℃, auto-controller control motor 13 is just changeing, at this moment, weight 21 moves downward, thereby driving water intaking flexible pipe 16 moves downward, when the temperature of being surveyed when the 4th temperature sensor 20 was lower than 40.8 ℃, auto-controller sends instruction shut down motor 13.The constant temperature water that water intaking flexible pipe 16 is drawn in the constant temperature water layer uses for bathing, continuous minimizing along with the water in the constant temperature layer, cold water constantly replenishes, water temperature constantly reduces, when the water temperature of being surveyed when the 4th temperature sensor 20 is lower than 39.2 ℃, and 13 counter-rotatings of auto-controller control motor, reel 11 drives water intaking flexible pipe 16 and moves up, when moving to 39.2 ℃, auto-controller disconnects the power supply of motor 13, makes water intaking flexible pipe 16 can supply the interior hot water of constant temperature water layer all the time.
When the water temperature in the storage tank 39 is higher or lower than design temperature,, turn-off motor powers by upper and lower limit travel switch 12,8, to guarantee the safe operation of system if motor 13 drives water intaking flexible pipes 16 when moving at the bottom of peak level place in the storage tank 39 or the case.
