Description

Electronic-controlled installation on a kind of solar water heater

The utility model relates to is electronic-controlled installation on a kind of solar water heater.

Solar water heater as thermal storage equipment popularization and application in daily life, be convenient to various hotels, hotel and family, this equipment is installed on the top in house usually, the irradiation of long-time easily reception light, better luminous energy is converted into heat energy by medium, makes water heating in the water tank.The water system of water tank just is fixed against the pressure of running water pipe, if the hydraulic pressure of running water pipe is too small, can't make water tank fill water at short notice, carry sometimes less than in the water tank at all, need etc. for a long time, carelessness is arranged slightly, and water valve is forgotten the pass, causes the waste of water, sometimes the water in the water tank uses up, forget that feed-tank adds water, cause the empty van insolation, cause equipment impaired.

The purpose of this utility model is to provide the electronic-controlled installation on the solar water heater that a kind of energy is safe, reliable, the maintenance water tank has water often.

The purpose of this utility model is achieved through the following technical solutions, electronic-controlled installation on the solar water heater comprises water tank, electronic control circuit, magnetic valve, be provided with two contacts in the water tank, be installed in the top and bottom of water tank respectively, two contacts are connected with electronic control circuit, also there is the contact to be connected on the housing of water tank with electronic control circuit, electronic control circuit is provided with relay, control magnetic valve by relay, magnetic valve is installed on the water supply pipe, and the control water tank is poured water; Electronic control circuit is made of triode, press button, resistance, electric capacity, indicator lamp, relay, indicator lamp E1 is connected on and shows relay work in the loop, and triode T3, T1 form multiple tube output and link to each other relay J 1 closure with relay J, the T2 conducting, contact J3 connects magnetic valve.

It is to adopt electronic circuit control magnetic valve feed-tank to pour water that good effect of the present utility model is embodied in this device, can work automatically, need not personnel look after, and the operating voltage of electronic control circuit is low, the use element is few, safe, reliable, Gu Zang leads low, in addition, solar water heater electronic-controlled installation ratio is installed is easier to, control also quite flexibly, the hot water in the water heater uses up, it can help you to fill automatically, does not need you and waits until water irritated again and leave; Sometimes temporarily cut off the water, you need not look after, and have electronic control circuit to control.Generally speaking, this equipment is electronic-controlled installation safe, reliable, that be suitable for.

The utility model is described in further detail in conjunction with the embodiments by accompanying drawing.

Fig. 1 is control circuit figure of the present utility model.

As can be seen from Figure 1, this device is made of water tank 1, magnetic valve 2, electronic control circuit 3, and electronic control circuit 3 is made of triode, press button, resistance, electric capacity, indicator lamp E1, indicator lamp E2, relay 5.Be provided with two contact A, C in the water tank 1, be installed in the top and bottom in the water tank 1 respectively, two contact A, C are connected with electronic control circuit 3, also there is contact B to be connected on the housing of water tank 1 with electronic control circuit 3, electronic control circuit 3 is provided with relay 5, control magnetic valve 2 by relay 5, magnetic valve 2 is installed on the pipeline of running water pipe 6, and the control feed-tank is poured water.

After electronic control circuit inserts civil power, get the work of 12V direct current electronic circuit through transformer 4 output lower pressure rectifier filtering, three contact A, B, C are placed on the different position of water tank respectively, it is negative potential that contact B is connected on the housing of water tank, contact A is placed the predetermined peak of cistern water level, and contact C places the minimum point of water level.The inlet channel of magnetic valve 2 control water tanks, when in the water tank when anhydrous, be that contact A, C be not when reaching water, triode T3 conducting, because there is R2 to supply with its positive bias, triode T3 and triode T1 form multiple tube, the T3 conducting, T1 is conducting also, and relay J gets electric adhesive, and indicator lamp E1 is connected on to show relay J work in the loop, the closed formation of the contact J1 of its relay self-insurance, make also conducting of T2, the contact J2 of relay connects magnetic valve 2 beginnings to cistern water supply, because the J2 action is extinguished indicator lamp E2.When water was raised to contact C, the T3 base stage ended T3 by the water negative voltage, and relay electric-loss is not worked, magnetic valve 2 is not worked yet, and stops to supply water, and this moment, water tank was also filled water, the normally-closed contact J2 conducting of relay, indicator lamp E2 is luminous, and full machine is in holding state, when water, water level reduces, contact A elder generation leaving water, electronic control circuit is not worked, and has only the water of waiting until to use up, when contact C breaks away from water level, triode T3 conducting, magnetic valve 2 water supply of starting working repeats the action of water.
