Abstract

An automatic water-supply instant heating solar water heater comprises a water-storage tank, a water inlet pipe and a sewer pipe, characterized in that an instant heating electrothermal water tube is arranged on the sewer pipe, and a magnetic valve is arranged on the water inlet pipe, wherein the magnetic valve and the instant heating electrothermal water tube are connected with a controller which comprises a water stage, an automatic water-supply controlling circuit and a water temperature and heating controlling circuit. The utility model employs the instant heating electrothermal water tube of small volume perfect as the auxiliary heating element of the solar water heater, which is integrated with the solar water inlet, the solar water outlet and the temperature and water level displaying and controlling box, and is designed in the room. When having sunlight or the indoor water temperature being over 45 degrees centigrade, the electrothermal water tube does not work, and when the water temperature is lower than 10 degree centigrade, the electrothermal water tube is power on and heated quickly to produce hot-water. If the water temperature is higher than 60 degrees centigrade, the electrothermal water tube is automatically powered off and stopped heating. The utility model also has the functions of automatic water-supply and the like, which are convenient to use.

Description

The automatic loading water instant heating solar water heater

Technical field

The utility model relates to solar water heater, especially a kind of automatic loading water instant heating solar water heater.

Background technology

Two shortcomings of common reflecting type evacuated solar device ubiquity, the one, can not produce hot water during no sunshine, auxiliary heat time heating time is oversize, and the storage water tank heat insulation water yield is limited; The 2nd, all to manually add water, use inconvenience.

Summary of the invention

The purpose of this utility model overcomes above-mentioned weak point exactly, and a kind of automatic loading water instant heating solar water heater easy to use is provided.

Automatic loading water instant heating solar water heater of the present utility model comprises storage tank, water inlet pipe, downcomer, establish the instant electric water pipe on the downcomer, be equipped with magnetic valve on the water inlet pipe, magnetic valve, instant electric water pipe link to each other with controller by lead, and controller comprises water level and automatic loading water control circuit, water temperature and heating control circuit.

Automatic loading water instant heating solar water heater of the present utility model adopts the small and exquisite instant electric water pipe of volume as the auxiliary heating of solar water heater element, shows that with solar energy water inlet, water outlet and temperature water level control cabinet combines together, and design is indoor.When having the sun or indoor water temperature to surpass 45 ℃, Electric water heating pipe is not worked, and when water temperature was lower than 10 ℃, Electric water heating pipe got electric Fast Heating and produces hot water, if water temperature is cut off the power supply when being higher than 60 ℃ automatically, stops heating.The utility model also has functions such as automatic loading water.

Fig. 3 is water temperature and heating control circuit figure.

The specific embodiment

A kind of automatic loading water instant heating solar water heater comprises storage tank 3, water inlet pipe 4, downcomer 2, establish instant electric water pipe 7 on the downcomer 2, instant electric water pipe 7 one ends and outlet pipe 6 join, be equipped with magnetic valve 5 on the water inlet pipe 4, magnetic valve 5, instant electric water pipe 7 link to each other with controller 1 by lead, and controller 1 comprises water level and automatic loading water control circuit, water temperature and heating control circuit.As Fig. 3,1., 2., 3., 4. Acc220 power supply one tunnel arrives electrothermal tube through the contact of relay J 1--J4, it is elementary that power transformer T is received through switch in another road, through transformer T step-down is the Ac16V power supply, bridge rectifier rectification through the D1-D4 composition, and be divided into two-way through the filtered DC voltage of C1, one tunnel power supply of making relay J 1--J4 wherein, another road is added to the input of three terminal regulator IC (7812), DC voltage is stablized in output after 7812 voltage stabilizings, makes the power supply of control circuit after C2 filtering.Control circuit is made up of Q1-Q5 and accessory circuit, during the anhydrous injection of instant electric water pipe 7, Q1 by → Q2 by → Q3, Q4 be saturated → Q5 ends, relay No1 dead electricity, its contact No1 open circuit, the power supply circuits of block system relay J1--J4, the contact of J1--J4 is 1., 2., 3., 4. disconnect, the power supply circuits dead electricity of instant electric water pipe 7 stops heating; When instant electric water pipe 7 has water to inject, then Q1 conducting → Q2 saturated → Q3, Q4 be by → Q5 conducting, relay No1 gets, the No1 closing of contact is if this moment, water temperature was lower than 45 ℃ then temperature controller contact K1 closure, if water level is higher than then water level controller contact K2 closure of lowest water level, relay J 1--J4 gets so, its contact 1., 2., 3., 4. closed, 7 pairs of current of instant electric water pipe heat, simultaneously LED ₄, LED ₅, LED ₆Show.If water temperature is higher than 60 ℃ of then temperature controller contact K1 automatic disconnections in the instant electric water pipe 7, cut off the power supply circuits of J1, J2,1., 2. the contact of J1, J2 disconnects, instant electric water pipe 7 dead electricity stop heating, and are same if storage tank 3 middle water levels are lower than then water level controller contact K2 automatic disconnection of lowest water level, cut off the power supply circuits of J3, J4,3., 4. the contact of J3, J4 disconnects, and instant electric water pipe 7 dead electricity stop heating.As Fig. 2, water level drops to LED in storage tank 3 ₁When extinguishing, this circuit is judged through program, the V1 conducting, and the relay J adhesive, magnetic valve 5 gets electric work, begins to storage tank 3 water fillings, along with storage tank 3 water levels constantly rise, indicator lamp LED ₁, LED ₂, LED ₃Light in succession, work as LED ₃After lighting, circuit upset output low level, V1 ends, and magnetic valve 5 cuts out, and stops water filling.
