Abstract

The present invention provides an automatic water control device of solar energy water heater with digital indicator of water storing quantity and capable of optionally setting water supplying quantity, which connects in series rotor wing or rotation water meter (1) in the water pipe of the solar energy water heater, and arranges a magnetic driver or a photoelectric marker (3) rotating with rotation shaft or counting gear (2) on the same, and arrange a magnetic coupling counting gear or a photoelectric coupler (4). The water storing quantity is displayed real time by the series combination gear (5) driving the display with the electronic measuring mechanism, a water quantity preset controlling device is arranged on the device, or the operation of the pulse electromagnetic valve is controlled by battery supplying power.

Description

Automatic water control device of solar energy water heater with numeral indication

Technical field:

The present invention relates to a kind of automatic water control device of solar energy water heater with numeral indication.

Technical background:

Solar water heater extensively enters average family.Many water heaters lack the water level indication, during last water, can only obtain the full information of water storage tank, a part of sensor that relies on several different heights of water level that are contained in roof hot-water device inside by overflowing backwater, segments is represented general water storage water level, and with water on the solenoid control.The former can not know the real-time water storage situation of water heater, also will set up a water return pipeline, has occupied limited building pipeline space.The latter also can only know the general water level of water storage tank, and error is bigger, the long-term faulty sensor that very easily causes metal device because of incrustation scale that uses, and the connection lead that also must haul out one group very long is indoor from the roof introducing, buries and draws the potential safety hazard that thunder is entered the room.

Summary of the invention:

The objective of the invention is to provide a kind of and need not increase outdoor pipeline in addition, (imbedded within the walls user as long as be connected in the aqueduct for pipeline, only need utilize threeway, just can directly be connected on bathing three water swivels), can be accurately with the unit of being upgraded to, utilize the just commentaries on classics (going up water) or the counter-rotating (water) of water meter to indicate actual water tank pondage, can arbitrarily set the water yield again, to adapt to the automatic water control device of solar energy water heater that illumination in winter deficiency improves water temperature with numeral.

Description of drawings:

With electrical schematic diagram mechanical measure control and electronic measurement control embodiment are advanced by reference to the accompanying drawings The row explanation.

Described the primary structure of automatic water control device in the accompanying drawing 1, accompanying drawing 2 is impulse electromagnetic valve Control circuit. In leading to the aqueduct of water heater, serial connection multi jet dry type vane wheel water meter (1), its Delivery port and water heater link, and water inlet is connected running water pipe with the bathing valve with through magnetic valve simultaneously The magnetic that road, the water wheels rotating shaft in water meter or counting gear (2) are equipped with thereupon rotation passes Driver (3) is to drive the with it corresponding magnetic coupling counting gear (4) that is located at the water meter top Rotate thereupon, or make magnetic coupler obtain the rotational pulse count signal, in mechanical metrological service, By the reduction of speed of serial change-speed gearing (5), the rotation revolution of the axis of rotation or counting gear in the future, Convert the angular metric corresponding with water tank volume to, drive pointer and produce deflection, with the fixed position The dial that indicates numeral consists of Water indicator (6), and also being provided with on dial can be with scale Mobile default upper water limiting switch (7), other is provided with manually upper water touch-switch (8), and is any When the time need to be gone up water, only need manual triggers (8) switch, battery supply (9) continues to commutation Electrical equipment (10) and impulse electromagnetic valve (11) power supply, because the work of relay, movable contact closes Close, magnetic valve (a) end is being for just, and opens and begin upper water, along with upper water process, indicator Throw of pointer touches preset switches (7) during to the scale position set, again sends out to magnetic valve Go out reverse impulse power supply [because relay coil can not get power supply, electric current can only pass through stationary contact, Make magnetic valve commutation (b) end for just closing], stop upper water. Accompanying drawing 3 is fixing dial, The throw of pointer illustrated embodiment, accompanying drawing 4 is fixed pointers, dial rotates illustrated embodiment. Accompanying drawing 5 is The electronic measurement electrical schematic diagram. In electronic measurement mechanism, from the pulse signal of magnetic coupler, Deliver to the forward-backward counter (JS) of series connection by shaping circuit and count (diagram 3 joints), and by Decoder (YM) is translated into numeral, makes in real time display water heater pondage of display (XS). Counter (JS) data output end is parallel with code switch (YS) in order to the default upper water yield, when When " addition " count output signal during upper water is consistent with default coding, the AND operation signal, Water in the shutoff of control magnetic valve (DCF) makes counter enter " subtraction " count status simultaneously. When bath water, the counter-rotating of water meter rotor makes cursor backward by the coupling of magnetic biography and travelling gear Or the circuit counting that subtracts, obtain the actual pondage indication of water heater. (KSS) in the electrical schematic diagram Being upper water control switch, (XL) is the automatic zero adjustment sensor, and effect is when water heater emptying Automatic clear is to eliminate the accumulated error of hot water or cold water's coefficient of expansion and evaporation.

Embodiment:

In the solar water heater aqueduct, be connected in series multi jet dry type vane wheel water meter (1), the magnetic that thereupon rotates is installed on its impeller shaft or counting gear (2) passes driver (3), supporting magnetic-coupled counting gear or the Hall device (4) of being equipped with above corresponding with it, drive water yield indicator (6) by combination speed gear (5) reduction of speed, the electrometer measuring mechanism is to drive device for digit-displaying (XS) by the digital circuit that includes up-down counter or microprocessor to show the water tank pondage in real time with numeral, device also is provided with water yield default control switch (7) and (YS) connects also control electromagnetic valve (11) and (DCF) work, or the temperature measurement unit of additional prior art, it is perfect that function more becomes.

Further improvement of the present invention is: water yield default control switch (7) adopts magnetic dry-reed pipe or stroke touch-switch to connect phase reversal relay gating pulse solenoid valve.
