Description of drawings

Fig. 1 is scheme of installation of the present invention.

The specific embodiment

Specify its implementation detail and operation principle below in conjunction with accompanying drawing:

As shown in Figure 1, this solar water heater workstation system, include first water pipe 1 and the water pump 7 that join with solar water heater's water tank 5, be provided with triple valve 6 between water pump 7 and the solar water heater's water tank 5, first interface of triple valve 6 is connected by first water pipe 1 and water tank 5, second interface of triple valve 6 is by the connection of second water pipe 2 with water pump 7, the other end of water pump 7 is connected by the 3rd water pipe 3 and feed water valve 8, connect between the 3rd interface of the 3rd water pipe 3 and triple valve 6 the 4th water pipe 4 is arranged, also connect on second water pipe 2 hot-water outlet pipe 9 is arranged, current in this hot-water outlet pipe 9 through a heating clamber 11 again from 12 li outflows of tap, be provided with three groups of electrical heating coils 10 in the heating clamber 11, also be provided with cooling-water temperature sensor 13 in this heating clamber 11, this cooling-water temperature sensor 13 and electrical heating coil 10, triple valve 6, feed water valve 8, water pump 7 and the level sensor that is positioned at water storage box are all by the unified control of control circuit.

Its operation principle is as follows: when the level sensor in the solar water heater water tank 5 is sensed the reservoir storage deficiency, send instruction and give control circuit, control circuit control feed water valve 8 is opened, triple valve 6 energisings, the 4th water pipe 4 is closed, first water pipe 1 and second water pipe 2 are connected, at this moment, water pump 7 work are extracted into water in the solar water heater water tank 5, when level sensor detects designated water level, automatically close feed water valve 8, triple valve 6 outages, water pump 7 quits work, and is after this heated by the water in 15 pairs of water tanks of solar thermal collector 5; When using hot water, fetch boiling water leading 12, current inductor 14 is sensed current, this moment is by triple valve 6, first water pipe 1 and second water pipe 2 are disconnected, and first water pipe 1 is communicated with the 4th water pipe 4, water pump 7 work superchargings, make hot water successively through first water pipe 1, the 4th water pipe 4, the 3rd water pipe 3, second water pipe 2, enter hot-water outlet pipe 9 at last.Because water inlet and the water outlet of solar water heater water tank 5 all are to utilize same water pump 7, under the prerequisite that satisfies water supply speed, have saved input cost.When being subjected to the rainy weather influence, when the water temperature in the solar water heater water tank does not reach design temperature, after coming out from hot-water outlet pipe 9 according to above-mentioned job step water, through a heating clamber 11, these heating clamber 11 volumes are little, three groups of electrical heating coils 10 are equipped with in the inside, when the current that temperature is on the low side pass through heating clamber 11, according to the gap size of actual water temperature and set water temperature, 10 groups of numbers of corresponding automatic unlatching electrical heating coil, 10 heating of electrical heating coil are exceedingly fast, the water that just flows through is heated to the water temperature of setting at once, thereby reach the temperature that the user sets, because the part that only is to use of electrical heating coil 10 heating, so saved electric energy to greatest extent.In addition, owing to use hot water to have the regular hour section, when water level is lower than a certain limit, will automatic water supplement, so occur water storage box water inlet and the simultaneous phenomenon of water outlet never.
