The instant heating supercharging device of solar water heater
Technical field
The utility model relates to the instant heating supercharging device of a kind of solar energy utilization technique, particularly a kind of solar water heater.
Technical background
Solar water heater is owing to the characteristics of its energy-saving and environmental protection are widely used, but solar water heater has also limited the impetus of its development owing to some shortcomings that himself exist, solar water heater on the Chinese market is non-bearing hot water device above 90% at present, this product economy material benefit, install simple, but its existence is maximum not enough: discharge pressure is low, and hot and cold water mixes inconvenient, and bathing is uncomfortable; Will bleed off ducted cold water earlier before using, the stand-by period is long, and causes a large amount of wastes of running water, and the bottom user is more obvious.Have the people to adopt tube emptying to solve the problem of arranging cold water earlier before the bathing on the market, but it is low not solve discharge pressure, the root problem of water resource waste.The someone uses two water pumps to be respectively applied for pipeline circulation and water outlet supercharging in addition, but expense height like this, and is commonly single tube up and down under the situation of water in the market solar water heater, two water pumps is installed and is realized that there is great difficulty in automatic control.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the instant heating supercharging device that a kind of instant-heating has the solar water heater of function of increasing pressure simultaneously.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of instant heating supercharging device of solar water heater, be characterized in: it is provided with a housing, be provided with water inlet pipe on housing top, lower housing portion is provided with outlet pipe, water inlet pipe communicates with the hot-water line of water heater water storage tank, the mixed water valve of outlet pipe and bathing joins, to the pipeline between the outlet pipe, be provided with circularly-supercharged pump and water flow switch at water inlet pipe, on circularly-supercharged pump and pipeline that water flow switch is connected, be provided with the return pipe that joins with the water heater upper hose, on the control line between water flow switch and the circularly-supercharged pump time delay module be housed.
The utility model uses the startup of water flow switch and the circularly-supercharged pump of the automatic control of time-delay control module and closes, and reaches with a pump and realizes that pipeline circulates and the purpose of two functions of water outlet supercharging.Concrete control method is: the control module of will delaying time is connected with water flow switch, circularly-supercharged pump, and wherein water flow switch is controlled the startup of circularly-supercharged pump automatically by the time-delay control module, and controls the startup of time delay module in the delay controller automatically; Behind the circularly-supercharged pump startup cold water in inlet channel and the water return pipeline is recycled to the water storage tank of water heater, makes outlet conduit be full of hot water, open mixed water valve again, promptly carve hot water, the circulating pump of supercharging simultaneously works on, and increases hot water effluent's pressure; Time delay module in the delay controller is closing of the circularly-supercharged pump of control automatically.Compared with prior art, the invention has the beneficial effects as follows: pipeline circulation and water outlet pressurization control are integrated into a set of equipment device, solve bathing simultaneously and put cold water earlier, cause the running water waste, stand-by period is long, and discharge pressure is low, the problem of bathing inconvenience, it is economical and practical, and is easy for installation.

The specific embodiment
A kind of solar water heater instant heating booster, it is provided with a housing 4, be provided with water inlet pipe 5 on housing 4 tops, housing 4 bottoms are provided with outlet pipe 8, water inlet pipe 5 communicates with the hot-water line of water heater water storage tank 6, outlet pipe 8 joins with the mixed water valve 9 of bathing, to the pipeline between the outlet pipe 8, be provided with circularly-supercharged pump 3 and water flow switch 1 at water inlet pipe 5, on circularly-supercharged pump 3 and pipeline that water flow switch 1 is connected, be provided with the return pipe 7 that joins with the water heater upper hose, on the control line between water flow switch 1 and the circularly-supercharged pump 3 time delay module 2 be housed.
Before the bathing, open and mix water valve 9, start circularly-supercharged pump 3 by water flow switch 1, close then and mix water valve 9, circularly-supercharged pump 3 beginning pipeline circulations, cold water in hot-water line and the return pipe is recycled to storage tank 6, open again and mix water valve hot water and flow out at once and need not to wait for that circulating pump uses as booster pump simultaneously, increase hot water effluent's pressure, bathing is closed mixed water valve after finishing, and circularly-supercharged pump 3 is cutting out after a bit of time of time-delay under 2 effects of time-delay control module automatically.
