Description

Automatic water filling solar water heater

The utility model relates to the automatic water filling solar water heater of a kind of energy that daily life field uses.

The solar water heater of Xiao Shouing in the market all is the mode that adopts artificial recharge, and the overflow by overflow pipe shows whether the water of water tank is filled with.This water flooding regime has many shortcomings, and first water filling is cumbersome; Second uses up the untimely water filling in back as the water in the water tank, very easily damages thermal-collecting tube; The 3rd must pay close attention to when water filling, overflows the formation waste otherwise just have a large amount of water from overflow pipe.

The purpose of this utility model provides a kind of water filling automatically and solar water heater continuous or segmentation demonstration fill level that can overcome above-mentioned shortcoming.

The purpose of this utility model is achieved through the following technical solutions: a kind of heat collector that comprises, the automatic water filling solar water heater of water tank and water-supply-pipe, it is characterized in that also being provided with by shell, the transformation rectification circuit, the controller that comparator constitutes, with manual water valve two ends on the water-supply-pipe and the magnetic valve that connects, capacitor C 1 in the transformation rectification circuit is in parallel with the relay J 1 in the comparator, water tank wall is fixed some probes from top to bottom successively, also be fixed with potentiometer on the water tank wall at nearly tank top place, the moving plate of potentiometer links to each other with buoy one end in being arranged on water tank, potentiometer, probe is through being fixed on the binding post access controller on the water tank, transformation rectified current routing transformer T1 in the controller, commutation diode D6～D9 and capacitor C 1 constitute; Comparator in the controller is by NAND gate circuit U1 (CD4011), electric R1～R7, and potentiometer W1, diode D1～D3, light emitting diode D4, D5, triode Q1, relay J 1, water flowmeter Q2, probe A, B, C and touch-switch K1, K2 constitute; Show in segmentation under the situation of water inlet, comparator in the controller is by NAND gate circuit U1 (CD4011), U2 (CD4011), resistance R 1～R6, R8～R15, diode D1～D3, light emitting diode D4, D5, D10～D13, triode Q1, relay J 1, probe A, B, C, D, E, F, G and touch-switch K1, K2 constitute; When being fixed on the water tank wall, probe answers sealed insulation.

The utility model is a kind of to be to show cistern water level continuously by water flowmeter, another kind is the bright segmentation demonstration cistern water level that puts out by light emitting diode, two kinds of modes all utilize water as the resistance between the probe, change the current potential height of comparator signal end, thereby change the duty of comparator circuit, the work of final control magnetic valve is finished into water or is stopped into water action.The utility model is simple in structure, and the user is brought great convenience, both can prolong the service life of thermal-collecting tube, and the water that can avoid waste again has favorable economic benefit.

Accompanying drawing 1 is the utility model controller, probe, magnetic valve mounting structure schematic diagram;

Accompanying drawing 2 is the continuous display circuit figure of the utility model controller;

Accompanying drawing 3 shows the circuit diagram of setting up for the segmentation of the utility model controller.

In the accompanying drawing: the 1st, controller, the 2nd, magnetic valve, the 3rd, water tank, the 4th, probe, the 5th, potentiometer (W1), the 6th, binding post, the 7th, buoy, diode D1～D3, light emitting diode D4, D5, D10～D13, commutation diode D6～D9, resistance R 1～R15, triode Q1, relay J 1, touch-switch K1, K2, NAND gate circuit U1, U2 (CD4011), transformer T1.

Further specify the utility model in conjunction with the accompanying drawings and embodiments, embodiment shows cistern water level continuously, by heat collector, water tank 3, water-supply-pipe, controller 1, probe 4 (is A, B, C), binding post 6; buoy 7 and; commutation diode D1～9; the transformation rectification circuit that capacitor C 1 constitutes and; resistance R 1～R7; potentiometer W1; diode D1～D3, light emitting diode D4～D5, triode Q1; relay J 1; water flowmeter Q2; touch-switch K1; K2 and magnetic valve 2 constitute, and during by dress, magnetic valve 2 is attempted by on the water pipe at former manual water valve two ends through water pipe; its objective is when occurring having a power failure, still can intake by manual water valve by NAND gate circuit U1 (CD401) by transformer T1.Practical work process is: three probe A, B, C of controller 1 lay respectively at the bottommost of water tank, the lower limit of water tank and the upper limit of water tank, and to make the A point be high potential, when water level when the B point is following, because B, C point breaks away from water and A, B, C is separated, NAND gate circuit U1 1., 2. the pin resistance grounded is a low level, so 3. pin is a high level, (12), (13) pin clamper is at high level, (11) pin then is a low level, therefore triode Q1 conducting, relay J 1 adhesive, magnetic valve 2 work water fillings.Simultaneously because 2. pin is a low level, 5., 6. pin also clamper is in low level, 4. pin is a high level, light emitting diode D5 is not luminous, in like manner D4 is not luminous yet.When water level is raised to more than the B point, when the C point was following, because A, B are connected to high potential, 2. pin was a high level, but 1. pin still is a low level, so 3. pin is a high level, 1. pin then is a low level, and magnetic valve 2 works on.When water level arrives the C point, A, B, 3 of C are connected to high potential, and 1., 2. pin is high level, 3. pin is a low level, (11) pin is a high level, Q1 ends, relay J 1 open circuit, and magnetic valve 2 quits work, because 1., 2. pin is a high level, so 5., 6., 8., 9. the equal clamper of pin is at high level, 4., 10. pin is a low level, D4, D5 are all luminous.When water level is reduced to the C point when following, breaking away from owing to C and A is electronegative potential.But (11) 1. the high level of pin makes pin still be high level through diode D2 clamper, and 3. pin then is a low level, and (11) pin is a high level, and triode Q1 continues to end.Because oppositely the ending of diode D1, so 8., 9. pin still is a low level, 10. pin is a high level, and therefore, light emitting diode D4 ends and extinguishes.When water level continues to drop to the B point when following, B point and A point break away from and are electronegative potential, and 2. pin is a low level, and 5., 6. pin is a low level, and 4. pin is a high level, and and solid light emitting diode D5 ends and extinguishes.Simultaneously since 2. pin be low level, 3., (12), (13) pin then be high level, (11) pin is a low level, triode Q1 conducting, magnetic valve 2 is started working.Water level is in more than the B point, during following any one position of C point, as the needs water filling, touches normally closed switch K1, and B is separated with A, and 1., 2. pin then is a low level, 3. pin is a high level, and (11) pin is a low level, triode Q1 conducting water filling.When not needing water filling, touch normal open switch K2, make C and A approaching, 1., 2. pin then is a high level, 3. pin is a low level, and (11) pin is a high level, and Q1 is by stopping water filling.Simultaneously, the voltage after the transformation rectification makes water flowmeter Q2 work through resistance R 7 potentiometer W1, when the water level of water tank raises or reduces, stirs potentiometer W1 by buoy, water flowmeter is deflected, thereby intuitively show the water level of water tank continuously.

Example two is that segmentation shows cistern water level, removes buoy 7, potentiometer W1 and water flowmeter Q2.Between water tank C, B two probes, insert four probes again five equilibrium, D, E, F, G, when water tank water was full, A, B, C, D, E, F, G were high potential, and D4, D5, D10, D11, D12, D13 are all bright.During water, cistern water level descends, and D, E, F, G, B, C are broken away from water one by one and separates with A point and to be electronegative potential, D5, D10, D11, D12, D13, D14 is extinguished successively, thereby reach the purpose of demonstration water volume in water tank.
