Abstract

The utility model relates to a full-automatic solar water heater which belongs to a solar water heater capable of automatically feeding water. The utility model is composed of a common water tank for a roof, a heat collector, water inlet and outlet pipes of the heat collector, a hot water pipe, water inlet and outlet pipes of a water heating tank, etc., wherein, the water inlet pipe of the water heating tank is bent into a reverse U shape and then is connected to the bottom of the water heating tank, and the highest point of the reversely U-shaped pipe is higher than or horizontal to the that of the water heating tank, and is provided with a one-way valve or an air inlet valve; the water outlet pipe of the water heating tank is connected with the upper part of the water heating tank, and the top of the water heating tank is also provided with an air discharging valve and an air inlet valve. The utility model has the advantages of firmness, lightning protection and safety, and can fully utilize the solar energy.

Description

The solar energy full-automatic water heater

The utility model belongs to solar water heater, especially belongs to the solar water heater of energy automatic water supplement.

Existing solar water heater, its water inlet pipe boiler bottom of directly packing into, check valve is housed on the water inlet pipe, because the boiler water inlet pipe is to fetch water from the outlet pipe of roofing common tank, and also connecting other, the outlet pipe of roofing common tank uses water swivel, the water level of the water table ratio boiler of these joints is low, in case check valve damages, because siphonage, the water of boiler just flows back to other and uses water swivel, the water of boiler is caused to do and is shone or dry combustion method by the boiler water inlet pipe time, damages solar water heater.Because boiler is a closed container, the turnover of water will influence the air pressure in the container after having a power failure, generally on the outlet pipe of boiler, scavenge trunk is housed, many thundery skies in south, be contained in scavenge trunk high on the roofing boiler, played the effect of lightning rod, and made whole water pipe charged, bring danger to the user, also influence attractive in appearance simultaneously.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of safe, firm solid solar energy full-automatic water heater is provided.

The technical solution adopted in the utility model is, the solar energy full-automatic water heater of forming by roofing common tank, solar thermal collector, heat collector inlet tube and outlet tube, boiler, boiler water inlet pipe and water outlet pipe, the water inlet pipe of boiler is for falling " U " shape pipe, connect with the bottom of boiler, the highest point of boiler water inlet pipe is higher than or is flat with the highest point of boiler, at the highest point of boiler water inlet pipe check valve or intake valve is housed.

Advantage of the present utility model is, the water inlet pipe of boiler has adopted " U " shape pipe, and the highest point of " U " shape pipe of falling is equipped with check valve, in case cut off the water or siphonage air that other reasons causes enters pipeline by check valve, siphonage is ended, avoided the current of boiler to lose.Water tank is made right circular cylinder shape, and the water in the minimizing boiler can effectively utilize energy because of the different heat exchanges that produce of water temperature, cancelled bleeder pipe, eliminated the hidden danger of being hit by thunder and lightning, the stainless steel hot water tank is radially rolled up muscle, axially be associated with reinforcement, make boiler more firmly solid.

Wherein 1 roofing common tank 2 boiler water inlet pipes, 21 check valves or intake valve 3 heat collectors 31 heat collector water inlet pipes 32 heat collector outlet pipes 4 boilers 41 boiler outlet pipes 42 vent valves 43 intake valves 44 electrically heated rods 45 reinforcements 46 outlet pipes 47 gate valves

Below in conjunction with accompanying drawing the utility model is described in detail

As Fig. 1, shown in Figure 2, the utility model is by roofing common tank 1, heat collector 3, heat collector water inlet pipe 31, heat collector outlet pipe 32, boiler 4, boiler outlet pipe 41 compositions such as grade, because the water outlet at cold day or overcast and rainy heat collector sometimes can't reach predetermined water temperature, in boiler, also increased electrically heated rod 44, the outlet pipe of boiler is contained in the top of hot water rod, push up along about 4～8 centimetres from boiler, boiler water inlet pipe 2 curves down " U " shape, be connected on the bottom of boiler, the highest point of boiler water inlet pipe 2, be higher than or flat with the top of boiler, highest point at the boiler water inlet pipe is equipped with check valve 21, has avoided owing to cut off the water or the caused siphon refluence of other reasons phenomenon.Stainless steel hot water tank 4 is hermetically sealed cylindrical, pass between its diameter D and the height H is D＜H＜1.8D, as boiler D is 76 centimetres, H is 100 centimetres, a vent valve 42 is equipped with at the top, an intake valve 43, the boiler external and internal pressure difference of Inlet and outlet water generation can be eliminated soon like this, during water inlet, the boiler internal pressure increases, vent valve 42 is opened, and bleeds off the gas in the boiler, and pressure is descended, when cutting off the water during the boiler water outlet, produce in the boiler and inhale vacuum, INO, gas flows into boiler.Boiler from the bottom about 1/3 place, increased an outlet pipe 46 and linked with outlet pipe 41, gate valve 47 is arranged on outlet pipe 46, when cutting off the water, do not have again in the weather of typhoon, open the gate valve 47 on the outlet pipe 46, hot water is flowed out by outlet pipe 46.In order to reduce cost, the stainless steel hot water tank adopts relatively thinner corrosion resistant plate to make, and for intensity and the rigidity of strengthening boiler, boiler is rolled up muscle and handled, and is furnished with reinforcement 45 vertically, and present embodiment is three reinforcements that equilateral triangle is arranged.

As shown in Figure 3, the user who does not have the roofing common tank, the boiler water inlet directly enters boiler by Running-water Company or water pump, requires the boiler bearing capacity to want big, the hot water tank top is made sphere, the vent valve 42 of boiler and intake valve 43 are contained in the top of sphere.
