Description

The freedom from repairs efficient solar water heater

Technical field the utility model relates to a kind of solar water heater that utilizes solar energy with the cold water heating, particularly a kind of freedom from repairs efficient solar water heater.

The background technology prior solar water heater all is that the heat that utilizes vacuum tube or heat pipe to absorb the sun is transmitted to the attemperater energy storage again, and the output of hot water depends on the quantity of thermal-collecting tube, and the hot water amount of actual output is by the capacity decision of attemperater.But be subjected to the restriction of multiple reasons such as mounting condition, in fact the attemperater of solar water heater can not do too big, so the hot water amount of actual output is not a lot.The subject matter that exists is: the hot water in the vacuum tube can not utilize; Aqueduct is very easily freezing under the situation of not doing the ribbon heater protection, the bad in the winter time use of solar water heater even resident family does not use the short time, also needs the water in attemperater and the water-supply-pipe is drained, otherwise just need prevent pipe freezeup with consumed power to ribbon heater energising heating; Drained because of the water in the attemperater on the other hand, store a spot of water in the vacuum tube and cause to have only, logical just tanning by the sun the water in the vacuum tube has been dried in a few days then caused the anhydrous empty solarization of vacuum tube, makes the vacuum tube state that reaches a high temperature, at this moment, if resident family's water filling in the attemperater, will cause the consequence of vacuum tube explosion, take place for fear of booster, prior solar water heater all need the user when no sunlight to the water heater water filling, this has just limited the service time of water heater.Present stage, solar water heater all was provided with the water level that automatically controlled facility or automatic spacing device are controlled attemperater; also need pipeline is done the ribbon heater protection at northern area; this has just increased the facility of solar water heater; parts have been increased; make structure become complicated, also increased the chance that fault takes place simultaneously.

Utility model content the purpose of this utility model be to provide the hot water in a kind of simple in structure, thermal-collecting tube can utilize, safe in utilization, booster, not congelative freedom from repairs efficient solar water heater can not take place.

Realize that the technical scheme that the purpose of this utility model is taked is: a kind of freedom from repairs efficient solar water heater, comprise attemperater, several thermal-collecting tubes, water inlet pipe, outlet pipe, water intaking valve, thermal-collecting tube and condenser hot well liner connect, it is characterized in that: be provided with the inner bag dividing plate in the attemperater, the inner bag dividing plate is divided into top inhalant region and bottom heat accumulation district with attemperater, on the inner bag dividing plate mozzle is housed, the upper port of mozzle is positioned at the top inhalant region, and the lower port of mozzle is positioned at and thermal-collecting tube, the outlet of water inlet pipe is positioned at the top inhalant region, the inlet of outlet pipe is positioned at the position of heat accumulation district, bottom near the inner bag dividing plate, and attemperater top is provided with the air inlet that communicates with the top inhalant region, and air inlet is equipped with intake valve.

The purpose that intake valve is set is to guarantee that water inlet pipe and outlet pipe have equal hydraulic pressure, and water tank overflow phenomena can not occur.During last water, cold water enters the top inhalant region of inner bag dividing plate top after the mozzle shunting enters thermal-collecting tube, hot water in the thermal-collecting tube is replaced the heat accumulation district, bottom of attemperater, and the hot water in bottom heat accumulation district is discharged for resident family by outlet pipe and is used, and realization utilizes the purpose of hot water in the thermal-collecting tube; When stopping water, close water intaking valve after, under the effect of atmospheric pressure, inlet open, atmosphere enter condenser hot well liner top inhalant region, and the ponding in water inlet pipe and the outlet pipe is discharged, and realize the pipeline emptying, thereby play antifreeze effect; After the water in the outlet conduit drains, because the inlet of outlet pipe is positioned at the position of heat accumulation district, bottom near the inner bag dividing plate, the liquid level in heat accumulation district, condenser hot well liner bottom keeps the horizontal plane of the inlet of outlet pipe, make in long period of time, even resident family does not use water heater, can not cause to be in the insolation state owing to thermal-collecting tube is anhydrous yet, thereby solve the booster problem of common water heater.

The utility model is simple in structure, rely on the pressure of running water to displace hot water, open outlet valve with regard to water outlet, no electrical control, safe in utilization, frozen pipe, booster, overflow and other regular maintenance need not be worried about by resident family, and because several thermal-collecting tube heat in the interior water obtain utilizing, have improved the effect of solar water heater greatly; It is the heavy duty detergent solar water heater of typically saving worry.
