Electrical equipment is powered, the corresponding normally opened contact closure of solid-state relay.
Flow direction 2 workflows of meter：When solar energy is intake, magnet steel 7 rushes at the left side by water, now attonity；When too
During positive energy water outlet, magnet steel 7 is rushed at the right, and close magnetic control inductive switch, magnetic control inductive switch closure, whole control loop connects
It is logical, after the solid-state relay in control loop is powered, normally opened contact K1 inhaled and, turned on by control loop, begin to warm up.When
When current stop or be reverse, magnet steel recovers position due to self gravitation.
The present invention gathers leaving water temperature using temperature sensor 3, and people are begun to flow out when using solar water heater
Cold water can allow it voluntarily to flow away and can not adopt an effective measure, and with the enhancing of people's awareness of saving energy, also coming up with many prevents
The method wasted water.Solution proposed by the present invention is the detection for installing a temperature sensor 3 to carry out leaving water temperature, is controlled
Device processed controls a normally-closed contact K2 according to the measurement temperature of temperature sensor 3, when the temperature of water is too low, controller control
Normally-closed contact K2 is failure to actuate.When the corresponding controlling switch of flow direction meter 2 is closed, begin to warm up, but we not can know that too
Whether the hot water in positive energy can use, and thus timely can not prepare for manual water adjusting valve, it is impossible in the sun
Hot water in energy water heater dispenses cold water after reaching, very dangerous.It is therefore necessary to a display unit is installed, in intelligence
System can have a display process when carrying out heating water distribution to the water temperature in pipeline, it is ensured that the safety of user.

It is not too big, save the space of pipeline and installation place.
(3) security：Because PTC heating needs powerful heater, the security that it is guaranteed when using is extremely heavy
Want, so the system needs to install temperature limiter additional.First temperature limiter is arranged in heating pipe, and its maximum temperature may be set in
Between 50-60 DEG C, so can ensure that it has the amount of stored heat seen, while it is also ensured that the temperature required for people.Once
When heating-up temperature reaches setting value, temperature limiter will cut off the electricity supply immediately, it is to avoid plus thermal runaway, cause the accident.
The course of work：When user's water, flow direction meter 2 detects that current direction is correct, and the relay switch of its control is normally opened
Contact k1 is closed, and ptc heater 1 is started working, water is heated rapidly, when the hot water in solar energy is reached at temperature sensor 3,
Signal transmission to single-chip microcomputer, is had monolithic processor controlled time-delay relay switch normally-closed contact k2 to disconnect, PTC by temperature sensor 3
