Abstract
This invention refers to a solar energy water heater with automatic dirt cleaning and emptying function, which contains water tank, solar energy vacuum pipe inserted in water tank, water supply and discharge pipe, emptying pipe, said water tank having horizontal pipe with water spraying holes towards the solar energy vacuum pipe, horizontal pipe connected with water supply and discharge pipe which connected with emptying valve through three-way valve.
Description
Technical field
The present invention relates to a kind of solar water heater, is automatic discharge-clean-drain-solar water heater specifically.
Background technology
Solar water heater can be divided into closing-sunning type and electron tubes type two big classes, and the passive solarenergy water heater is substituted by vacuum pipe solar water heater gradually owing to the thermal efficiency is low.Water in the conventional vacuum tubular type solar water heater water tank is communicated with the water in the vacuum tube, absorbs heat by vacuum tube, through the circulation of water the water in the water tank is burnt heat.Also has a kind of solar water heater that adopts full glass duplex tube, vacuum tube is sealed at both ends, wherein there is not water, but heating agent is housed, the lower end of vacuum tube is that heat absorbing end is exposed in the sunshine, and the upper end is a release end of heat, is inserted in the water tank, heat absorbing end is delivered to release end of heat by heating agent after absorbing heat, with the heating of the water around the release end of heat.But there are several defectives in these vacuum pipe solar water heaters: 1) winter, upper and lower conduit froze easily, and especially in northern city, upper and lower conduit caused whole solar water heater not use when temperature was lower than subzero ten degree, and is serious even freeze the one's water breaks pipe.2) after long-time the use, have incrustation scale or other dirts on water tank or the vacuum tube, reduce normally use of thermal conversion efficiency, influence.
Summary of the invention
The purpose of this invention is to provide a kind of automatic discharge-clean-drain-solar water heater simple in structure.
For achieving the above object, the present invention adopts following technical scheme:
Automatic discharge-clean-drain-solar water heater of the present invention comprises water tank, is inserted into the solar energy vacuum tube in the water tank, water tank is connected with upper and lower conduit and evacuated tube, be horizontally disposed with transverse tube in the water tank, have hole for water spraying on the sidewall of transverse tube, the opening of the hole for water spraying on the transverse tube is towards solar energy vacuum tube, transverse tube is communicated with upper and lower conduit, passes from the upper end of water tank, is positioned on the outer upper and lower conduit of water tank to be connected with exhaust-valve by three-way pipe.
Described transverse tube is the U-shaped pipe, and its termination is sealed, is fixed on the sidewall of water tank, and the two ends of U-shaped pipe lay respectively at the above and below of solar energy vacuum tube.
The bottom of water tank has sewage draining exit, connects blow-off pipe on the sewage draining exit, has the blow-off pipe magnetic valve on the blow-off pipe.
Described solar energy vacuum tube is full glass duplex tube.
Described exhaust-valve can be that magnetic valve also can be a hand-operated valve.
Described transverse tube can be a straight tube also, is positioned at the top of solar energy vacuum tube, and the one end seals, is fixed on the sidewall of water tank, and the other end is communicated with upper and lower conduit.
After adopting technique scheme, automatic discharge-clean-drain-solar water heater of the present invention not only can be realized water pipe emptying in winter, also has the function of automatic cleaning water tank, blowdown simultaneously.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the A-A cutaway view of Fig. 1 embodiment;
Fig. 3 is the structural representation of another embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, automatic discharge-clean-drain-solar water heater of the present invention comprises water tank 1, is inserted into the solar energy vacuum tube 2 in the water tank 1, solar energy vacuum tube 2 is preferably selected full glass duplex tube for use, since anhydrous in this vacuum tube, also just avoided dirt to enter the trouble that vacuum tube brings.Be connected with upper and lower conduit 3 and evacuated tube 4 above the water tank 1, be horizontally disposed with the transverse tube 5 of U-shaped in the water tank 1, its termination is sealed, is fixed on the sidewall of water tank 1, the two ends of U-shaped pipe lay respectively at the above and below of solar energy vacuum tube 2, have hole for water spraying on the sidewall of transverse tube 5, the opening of hole for water spraying is towards solar energy vacuum tube 2, and transverse tube 5 is communicated with upper and lower conduit 3, upper and lower conduit 3 passes from the upper end of water tank 1, is connected with exhaust-valve 6 in the outside of water tank 1 by three-way pipe.Exhaust-valve 6 can be that magnetic valve also can be a hand-operated valve, it can be installed in when adopting magnetic valve outdoor, by being installed in indoor controller control emptying; If it is indoor to adopt hand-operated valve it to be installed in by the pipeline that prolongs, can be directly in indoor control emptying during use.
Accumulate in dirt in the water tank for the ease of eliminating, sewage draining exit has been installed, connect blow-off pipe on the sewage draining exit, have blow-off pipe magnetic valve 7 on the blow-off pipe in the bottom of water tank 1.
As shown in Figure 3, as an alternative embodiment of the invention, transverse tube 5 can be a straight tube also, is positioned at the top of solar energy vacuum tube 2, and the one end seals, is fixed on the sidewall of water tank 1, and the other end is communicated with upper and lower conduit 3.
During use, exhaust-valve 6 is closed, supply water to water tank 1 by upper and lower conduit 3, water sprays from hole for water spraying by upper and lower conduit 3, transverse tube 5, solar energy vacuum tube 2 and water tank 1 is had the effect of cleaning, because what adopt is full glass duplex tube, solar energy vacuum tube 2 seals, and does not also just have dirt certainly, and the dirt in the use all accumulates in the water tank 1.When the dirt in the water tank 1 is many, can open magnetic valve 7, dirt is discharged.
Behind filling up water in the water tank 1, also be full of water in the upper and lower conduit 3, as long as close the water supply valve door this moment, the Draw off valve of opening installation on upper and lower conduit 3, water will enter Draw off valve by transverse tube 5, upper and lower conduit 3 under siphonage, uses for the user.
When environment temperature is very low, can open exhaust-valve 6 earlier, open Draw off valve again, this moment, upper and lower conduit 3 was communicated with atmosphere, had lost siphonage, had only the water in the upper and lower conduit 3 to be emitted.Emptying upper and lower conduit 3 under low temperature environment, can not freeze yet.And the water in the water tank 1 still can be by solar energy heating.When the user prepares to reuse,, close water supply valve again and can normally use as long as under the situation of closing exhaust-valve 6, open water supply valve with filling up water in the upper and lower conduit 3.
