Accompanying drawing 1 is a kind of structural representation of the present utility model;

Accompanying drawing 2 is a kind of schematic diagrams of the present utility model.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: a kind of water-temperature water-level is the solar water heater of control automatically, comprise water tank 1, water inlet pipe 10 and control circuit, be provided with water level water pipe 2 in water tank 1 one sides, a magnetic ball float 3 is set in the water level water pipe 2, its bottom is conducted by communicating pipe 5 and water tank 1, water level water pipe 2 sidewalls are provided with the tongue tube 4 of test water level, and by the lead-in wire link to each other with controller, the initial water level of tongue tube 4 tests is set to 10%, increase progressively by 1.4 multiplying powers later on, up to 100%, be provided with temp probe 6 in the water tank 1, link to each other with controller by lead-in wire, the lower corner of water tank 1 one sides is provided with terminal plate 18, be provided with photodiode 7 above the water tank 1, photodiode 7 is placed in the place, Chaoyang, its top is provided with a translucent glass 8, its west side vertically is provided with shading baffle plate 9, the height of shading baffle plate 9 roughly is advisable with the sight shaded side that at 4 o'clock in afternoon, photodiode 7 was in shading baffle plate 9, this highly can be determined by experiment, water inlet pipe 10 is provided with ball valve 11, be provided with check valve 17 before it, on the described ball valve 11 switch fluted disc 12 be set, setting only touches protruding 16 on it, and close contact 14 and open contact 15 in water inlet pipe 10 arranged outside, its termination touch protruding 16 with close contact 14 and open contact 15 and match, switch fluted disc 12 other settings by motor-driven small tooth plate 13, wherein small tooth plate 13 matches with switch fluted disc 12.

Its course of work is as follows: daytime, water temperature rose in the water tank when sunny, and photodiode will have optical signal to send controller to, and controller detects water temperature and the water level in the water tank.If water tank less than, and water temperature is higher than 60 ℃, and controller sends and adds water signal, electric motor starting, the driving small tooth plate rotates, the switch fluted disc that small tooth plate drives ball valve rotates, and only touches the protruding pass contact that leaves, and opens contact up to contact, controller sends signal, motor stops operating, and adds in the water process, and water temperature descends, when water temperature is lower than 60 ℃, when adding water to next water level by water-level detecting, controller sends and stops to add the water signal, the motor counter-rotating, close contact up to only touching protruding contact, motor stops operating, and repeats this process, and water is full in water tank, water-level detecting sends the full signal of water and gives controller, if after this sunny, water temperature also can continue to rise in the water tank, but controller can not send again and adds the water signal.After about 4 o'clock of afternoon, because the shading baffle plate is set, solar radiation is less than photodiode, and photodiode has no longer transmitted optical signal and given controller, and the controller outage is no longer worked, and has transmitted optical signal once more up to photodiode.
