The length that described cold water injects core 10 is identical with hot water water storage cylinder 8 inner length, cold water injection core 10 is provided with tiny cold water injection core and portals 13, cold water inject core portal 13 the distribution of unit are of portalling front sparse rear intensive, make outlet water at tail end rate close with front end water rate, convection current cage 9 is provided with tiny portalling, the distribution of unit are of portalling is front sparse rear intensive, for ensureing that outlet water at tail end rate is close with front end water rate, cold water is slowly oozed out from whole stream cage 9 surface.
Described Air ball valve 4 is provided with pneumatics adjusting rod 14, for regulating ball float position.
Described heating in vacuum pipe 7 adopts and adds heavy sheet glass, and professional etiquette of going forward side by side constant-pressure is tested.
After hot water flows out, a high position is flowed to by hot water delivery pipe 7, need pressurization, by means of the pressure of extraneous cold water, high-pressure cold water enters and is sealed into water tank 5, cistern water level raises, along with the rising of water level, Air ball valve 4 spheroid rises, close Air ball valve 4, be sealed into water tank 5 internal pressure to increase, compress the air of inner tank simultaneously, pressure energy hot water now can be thus lifted to the position higher than hot water water storage cylinder 8 one to two meters, pressure now in hot water water storage cylinder 8 and heating in vacuum pipe 11 increases, because heating in vacuum pipe 11 can not bear excessive pressure, therefore necessary pressure limiting, after water constantly flows into and is sealed into water tank 5, now Air ball valve 4 is closed, after water level rises, water intake ball valve 3 is closed, water inlet is closed, now hydraulic pressure is not just in increase, arranged by two ball valve, pressure is made to maintain a suitable scope.
Operation principle of the present invention is: the present invention measures system and compression system is formed by increasing hot water effluent.
Increase hot water effluent and measure system: original inlet water tank is transform as and is sealed into water tank 5, sealing inlet water tank 5 arrange be added with cushion rubber be sealed into tank lid 1, snap close 2 will be sealed into tank lid 1 and tightly be buckled in and be sealed on water tank 5, sealing inlet water tank is hedged off from the outer world, the water inlet end be sealed in water tank arranges water intake ball valve 3, water side arranges Air ball valve 4, the water side be sealed into outside water tank is water inlet pipe 6, the cold water that cold water enters in hot water water storage cylinder 8 injects core 10, cold water injection core 10 is provided with cold water injection core and portals 13, inject on core 13 at cold water and be provided with convection current cage 9, an enclosure space is formed bottom convection current cage and hot water water storage cylinder 8, cold water injects core 10 and is positioned at this enclosure space, cold water by inject core portal 13 ooze out after enter this enclosure space after evenly slowly oozed out by convection current cage 9, hot water water storage cylinder 8 is connected in series heating in vacuum pipe 11, hot water exports to user's supplying hot water by hot water delivery pipe 7.
The length that cold water injects core 10 is identical with hot water water storage cylinder 8 inner length, and cold water injection core 10 is provided with tiny cold water injection core and portals 13, and the distribution of unit are of portalling is front sparse rear intensive, ensures that outlet water at tail end rate is close with front end water rate.Convection current cage 9 is provided with tiny portalling, and the distribution of unit are of portalling is front sparse rear intensive, requires that outlet water at tail end rate is close with front end water rate, and cold water slowly can be oozed out from whole stream cage 9 surface.
The proportion of hot water is lighter than cold water, and cold water slowly oozes out from stream cage 9 surface, and hot and cold water proportion is not identical, cold water and hot water layering, and cold water is by hot water upwards lifting, and hot water flows out from hot-water line.Slow due to what arrange that cold water injects that core 10 and convection current cage 9 make the mixing of hot water and cold water become, after high-temperature-hot-water flows to end, outflow cold water, whole like this hot water water storage cylinder 8 is almost all utilized, and improves the utilization rate of hot water.Water heater in the past goes out hot water while supplement cold water, and hot and cold water mixes rapidly, and in hot water water storage cylinder 8, hot water temperature declines rapidly, greatly reduces the utilization rate of hot water.
Air ball valve 4 is provided with pneumatics adjusting rod 14, can regulate ball float position.
Compression system: after hot water flows out, a high position is flowed to by hot water delivery pipe 7, need pressurization, by means of the pressure of extraneous cold water, high-pressure cold water enters and is sealed into water tank 5, cistern water level raises, along with the rising of water level, Air ball valve 4 spheroid rises, close Air ball valve 4, be sealed into water tank 5 internal pressure to increase, compress the air of inner tank simultaneously, pressure energy hot water now can be thus lifted to the position higher than hot water water storage cylinder 8 one to two meters, pressure now in hot water water storage cylinder 8 and heating in vacuum pipe 11 increases, because heating in vacuum pipe 11 can not bear excessive pressure, therefore necessary pressure limiting, after water constantly flows into and is sealed into water tank 5, now Air ball valve 4 is closed, after water level rises, water intake ball valve 3 is closed, water inlet is closed, now hydraulic pressure is not just in increase, arranged by two ball valve, pressure is made to maintain a suitable scope.
The invention has the beneficial effects as follows:
The present invention has fully utilized solar energy; solve out the difficult problem at the bottom of hot water efficiency; utilize cold water water pressure to promote hot water output pressure; two ball valve is adopted to arrange; make pressure maintain a suitable scope, protect heating in vacuum pipe, achieve the requirement that solar water heater is placed on balcony; cost increases seldom on the basis of original solar energy, has and well promotes and practical value.
