Description

The solar water heater of rapid and uniform heating and dynamic heat method thereof

Technical field

The invention belongs to technical field of water heaters, relate to a kind of solar water heater and dynamic heat method thereof of rapid and uniform heating.

Background technology

Raising along with people's living standard, solar water heater has entered huge numbers of families, hot water is widely used in having a bath, washes one's hands, does washing, washes the dishes, washes dish etc., particularly in the winter time, the consumption of hot water is big, this just makes the water tank design capacity of solar water heater increasing, water tank is more and more longer, just equilibrium of the water temperature in the heating process and firing rate has been proposed higher requirement.The solar water heater of at present big volume, the overcast and rainy heat pump heat exchanger that no matter adopts still adopts electric heating tube to assist the solar water heater of heating as heater, need set water temperature before using, when hot water reaches set water temperature, stop to heat to obtain hot water by the temperature controller outage.The subject matter of its existence is: heater is positioned at a side of water tank, heat transmission between heating Kao Shui and the water realizes, there is the tangible temperature difference in the hot water water temperature of inner bag both sides, one side water temperature of having heaters is higher for a long time, the easy scaling of heater, cause the reduction of the heater thermal efficiency, service life to shorten, firing rate is slow and energy consumption is big, and sometimes hot and sometimes cold phenomenon appears in the hot water water temperature of supply; Must emit the interior cold water of outlet pipe earlier before having use hot water, just go out the problem of hot water then.

Summary of the invention

Purpose of the present invention just provides a kind of solar water heater and dynamic heat method thereof of energy rapid and uniform heating.

The present invention can be realized by following mode: solar water heater comprises shell, heat-insulation layer, inner bag, heat collector and support, inner bag one side is provided with water inlet pipe, the inner bag opposite side is provided with outlet pipe and heater, be connected to valve on the outlet pipe, described inner bag one side is provided with the circulation water inlet, the circulation water inlet is connected to water circulating pump by circulation pipe, and water circulating pump is connected on the circulating outlet through circulation pipe.

The improved technical scheme of the present invention is: be provided with normally open solenoid valve between circulation water inlet and the water circulating pump, the circulation pipe between water circulating pump and the normally open solenoid valve is provided with three ports, and three ports are connected on the outlet pipe by return pipe.

Dynamic heat method of the present invention, when the heater of solar water heater was switched on, heater gave out heat energy to the water transmission, starts water circulating pump synchronously, and hot water enters circulation pipe by circulating outlet and flows into inner bag through the circulation water inlet; When hot water reached design temperature, heater stopped heating, and water circulating pump cuts off the power supply automatically, stops the hot water at inner bag two ends is circulated, thereby has realized the hot water dynamic heat; When using hot water, open delay switch earlier, water circulating pump work, normally open solenoid valve are closed, hot water flows to outlet pipe through three ports by return pipe by circulation pipe, make cold-water reflux in the outlet pipe to inner bag, allow be full of hot water, the valve open instant-heating and outlet hot in the outlet pipe.

The present invention to the water promotion that circulates, is evenly distributed the hot water of inner bag the inside by the small water circulating pump of power consumption, and the water outlet water temperature does not have the temperature difference, has improved the comfort level of shower greatly; Can faster evenly heat acquisition hot water, thereby service life, heat time heating time with minimizing heater incrustation scale generation prolongation heater are short, efficient is high, the characteristics of features simple structure.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the structural representation of the vertical water tank of the present invention.

In the drawings: inner bag 1, heat-insulation layer 2, shell 3, heater 4, circulating outlet 5, circulation water inlet 6, circulation pipe 7, water circulating pump 8, return pipe 9, normally open solenoid valve 10, water inlet pipe 11, outlet pipe 12, valve 13.

The specific embodiment

Below in conjunction with embodiment, the invention will be further described, but it is not represented as unique embodiment of the present invention.

Embodiment one

Please read Fig. 1, solar water heater comprises shell 3, heat-insulation layer 2, inner bag 1, heat collector and support, inner bag 1 one sides are provided with water inlet pipe 11, inner bag 1 opposite side is provided with outlet pipe 12 and heater 4, be connected on the outlet pipe 12 with penstock 13, inner bag 1 one sides are provided with circulation water inlet 6, and circulation water inlet 6 is connected to water circulating pump 8 by circulation pipe 7, and water circulating pump 8 is connected on the circulating outlet 5 through circulation pipe 7.In addition, can between circulation water inlet 6 and water circulating pump 8, be provided with normally open solenoid valve 10, circulation pipe 7 between water circulating pump 8 and the normally open solenoid valve 10 is provided with three ports, three ports are connected on the outlet pipe 12 by return pipe 9, make the cold water of storage in the solar water heater outlet pipe 12 realize backflow functionality, cold-water reflux to inner bag 1, has been solved and used the cold water that must give off earlier before the hot water in the water pipe 12, just go out the problem of hot water then, thus the conserve water resource.Circulation pipe 7, water circulating pump 8 and normally open solenoid valve 10 can be installed in the heat-insulation layer 2, also can be installed in outside the shell 3.

Embodiment two

Please read Fig. 2, Fig. 2 is one embodiment of the present of invention, and water tank is vertical structural representation, and its structure is identical with embodiment one with connected mode.

When the present invention used, water circulating pump 8 was connected with the circuit of heater 4, realized synchronous working or water circulating pump 8 discontinuity work; When outlet pipe 12 backflow functionality were enabled, water circulating pump 8 was connected with the circuit of normally open solenoid valve 10, by delayer control, realized synchronous working.

When overcast and rainy solar water heater water-temperature is low, heater 4 energisings with solar water heater, heater 4 gives out heat energy to the water transmission, start synchronously water circulating pump 8, hot water enters circulation pipe 7 by circulating outlet 5 and flows into inner bags 1 through circulation water inlet 6, and the hot water at inner bag 1 two ends is circulated, hot water in the inner bag 1 is evenly distributed, the hot water water temperature does not have the temperature difference, has shortened heat time heating time greatly, reduces the generation of heater 4 incrustation scales; When hot water reached design temperature, heater 4 stopped heating, and water circulating pump 8 cuts off the power supply automatically, and water circulating pump 8 stops the hot water at inner bag 1 two ends is circulated, and finishes heating process one time; Before using hot water, open delay switch earlier, energising is closed water circulating pump 8 work, normally open solenoid valve 10, hot water flows to outlet pipe 12 through three ports by return pipe 9 by circulation pipe 7, make cold-water reflux in the outlet pipe 12 to inner bag 1, allow be full of hot water in the outlet pipe 12, reach the purpose of opening instant-heating and outlet hot with penstock 13, save water resource, improved the comfort level of using hot water.
