Abstract

A solar water heater system for fast heating and preferential discharge of hot water aims at solving the disadvantages of the existing solar water heaters. Hot water produced by the solar water heateris concentrated at an upper part of cold water by a simple facility with simple structure, convenience and applicability, thus the hot water can be discharged when the water is not added to a lower p art and the hot water is always preferentially discharged. A tee 1 is arranged at a water pipe joint in an inner tank of the solar water heater, one joint of the tee is connected with a full water self-closing valve 2, a water intake check valve 3 and a water inlet pipe 4, and the other joint of the tee is connected with a drainage check valve 5, a drainage pipe 8 and a water float 10. As the water float always drives the drainage pipe 8 and a hot water collecting pipe 9 to float on water surface, the heated water in a vacuum tube always can be collected on water surface by the hot water collecting pipe 9; and the drainage pipe 8 always keeps preferentially discharging the hot water at the upper part, and the full water self-closing valve 2 can automatically stop adding water when a water tank is full of water. The system can improve properties of the solar water heater and effectively increase user satisfaction.

Description

Solar water heater is rapidly heated and preferentially discharges hot-water heating system

One, technical field

The present invention relates to solar water heater, is the device that a kind of solar water heater was rapidly heated and can preferentially discharges hot water.

Two, background technology

There is following defective in solar water heater in the market: the water in the water heater is whole slowly to heat up basically, and it is longer like this bucketful water to be heated to the time that required temperature uses, and cannot take hot water as early as possible; Another, after replenishing cold water in the water heater of Xiang Yuyou part hot water, as without shining upon intensification, when needing to use hot water, just can emit hot water after will discharging the cold water that afterwards injects earlier, sometimes can't give off hot water because the cold water that injects is too many, not only inconvenience but also waste water resource, this situation often runs into.

Three, summary of the invention

The present invention is intended to solve the above-mentioned defective that existing solar water heater exists, the minimum facility that adopts a kind of convenience simple in structure to be suitable for, can make water heater can discharge hot water as early as possible---when water in water tank all is not heated, can wash, again can be after injecting cold water, still can normally use remaining hot water, effectively improve the performance of water heater.

Four, the technical solution used in the present invention

(advance row) hose nozzle connects a threeway earlier in water heater liner, and the full self-closing valve of threeway a bite water receiving taps into water one-way valve (from then on valve supplementing water in water tank, outwards draining) behind the valve; After connect the water pipe that one section below has some apertures again.

Adorn a check valve of water drainage (this valve guarantee can only by the outside draining of water tank) in another interface of threeway, connect a rotary elbow bend again, connect a drainpipe behind the elbow, the drainpipe end connects an elbow that Open Side Down, adorn a water in the elbow floating, water floats the lifting with the lifting of the water surface, drives elbow bend and rotates, and guarantees to be in all the time under the water surface about 1.5cm with the floating draining mouth of pipe that links to each other of water.

Each heat collecting vacuum pipe mouth covers most, and forms a seal heat-collecting chamber with water tank wall with a groove shape stainless steel iron sheet in the water tank; All insert a suitably long separate sheet in each vacuum tube, the separate sheet upper end links to each other with groove shape iron sheet edge.

On water is floating, fix an opening in addition over against the water surface, the thermal-collecting tube parallel, isometric with drainpipe, rotating elbow bend is also loaded onto in the thermal-collecting tube below, this elbow is with draining elbow bend (make thermal-collecting tube and drainpipe can with floating the moving up and down and rotate of water) dorsad, links to each other with the water pipe of one section band temperature-sensing valve in the heat collecting chamber.This device can focus on the cold water top to the water that is heated to uniform temperature at any time, and can preferentially discharge upper strata hot water all the time.

Beneficial effect is: the moisture step heating in the water tank, the water that heated is because density is less, this device makes hot water and cold water natural separation, can take warmed-up water at any time, shorten the stand-by period, and can preferentially discharge hot water all the time, and when surplus when part hot water is arranged in the water tank, after inwardly additional cold, still can use down remaining hot water, effectively improve the performance of water heater.

Five, specific embodiments

(1) introduces embodiment of the present invention below in conjunction with accompanying drawing.

After filling with water in the solar water heater, under the irradiation of the sun, the water heat absorption in the vacuum tube heats up, because more than 4 degree C, along with the density of temperature rising water is more and more littler, warmed-up water density diminishes and enters heat collecting chamber 13 along vacuum tube upper side wall (because vacuum tube is to tilt to install).Initial heat collecting chamber temperature control valve closing, (this temperature is a design temperature when heat collecting chamber's water temperature is raised to 50 degree C, also can be set at 60 degree C or other temperature), the temperature controller valve begins to open gradually, hot water upwards enters the top layer of the water tank water surface along hot-water collection pipe, and water is warm more in the heat collecting chamber, and the temperature-sensing valve door opening is big more, promptly along with the power of sunlight, the temperature control valve can be regulated automatically.(under the drive of water float 10, elbow bend 6,7 rotates, and the mouth of pipe top of hot-water collection pipe 9 is all the time above water, and mouth of pipe bottom is all the time in horizontal plane bottom, and the water after guaranteeing to heat can circulate and rise to water surface top; The mouth of pipe of drainpipe 8 can preferentially discharge the hot water on top following about 1.5 centimetres of the water surface when guaranteeing draining, and hot water layer's thickness will surpass 1.5cm.) cold water enters in the vacuum tube along separate sheet below vacuum tube downside and heat, and enters heat collecting chamber along vacuum tube upper side wall separate sheet top again after the heating, rises to water tank water surface topmost through hot-water collection pipe.This process continues up to the water in the water tank is all heated.After heating process in temperature-sensing valve open all the time, the water of water tank bottom constantly enter vacuum tube obtain the heating, the highest water of temperature that heated is delivered to water surface top, this process goes on when solar radiation is arranged always.

After a part of water is heated,, can give off hot water by drainpipe 8 as need hot water.

After hot water spends a part, when water tank replenishes cold water, because the effect of check valve of water drainage and water inlet check valve, cold water can only slowly inject the water tank bottom from water inlet pipe 4, and hot water floats over top. after the water filling, reusable heat water, under the effect of two check valves, that emits from drainpipe 8 is still hot water, injects not influence behind the cold water and continues to use remaining hot water, hot water in the water heater can fully obtain utilizing, thereby has improved the performance of solar water heater.

Referring to accompanying drawing (four), after filling with water in the water tank, the full water self-closing valve just rotates to closed condition under the drive of water float 14, stops to go up water automatically.From indoor water filling to water-heater water tank, with from water heater to the indoor usefulness mostly of putting hot water now be same branching pipe, first at indoor water supply valve of closing water one valve in the draining during with hot water by the user, put hot water again; Opening water supply valve during last water gets final product.

Rotatable right-angle elbow pipe structure is referring to accompanying drawing (five).

The temperature controller structure is referring to accompanying drawing (six), and its course of work is as follows:

When water temperature be lower than set temperature (as 50 the degree C) time, valve closing; When temperature reaches when setting temperature, because the linear expansion coefficient of certain plastic tube is much larger than the linear expansion coefficient of metal frame, plastic tube expands and increases, be equivalent to supporting-point and be moved to the left, thus the lever arm end 6 of metal frame, and amount of movement left is bigger, pulling valve vane hole 2 opens blade.Hot water rises to the water tank water surface by valve along thermal-collecting tube.When temperature is lower than design temperature, plastic tube shrinks, under the effect of spring, the relative Shen of temperature controller metal lever arm is long, the closed mouth of pipe of blade, stop the liter waterborne that is not heated to design temperature, thereby guaranteed the temperature of upper water. because lever arm end 6 is ring-type, when heat collecting chamber's water temperature was lower, lever arm Shen again was long, inoperative to blade, the mouth of pipe is closed all the time.For making the temperature control valve set under the temperature tight-closedly, can be contained in (linear expansion coefficient of invar pipe is identical with metal frame and valve sheet) on a bit of steel pipe to valve and valve frame earlier, again this section steel pipe is linked to each other with the temperature controller plastic tube.

Native system has following function:

One, makes that warmed-up water all concentrates on cold water top in the water tank, can use hot water after a part of water is heated in water tank, shortened the time that can give off hot water;

Two, can preferentially discharge hot water, when part hot water is arranged in water tank, in water tank, replenished cold water after, outwards preferential discharging hot water, remaining hot water still can continue to utilize;

Three, in the water tank behind the filling up water, can stop automatically going up water, avoid water from water tank, to overflow, and water tank not bear the hydraulic pressure of water pipe.
