Abstract

The utility model discloses a solar water heater utilizing a siphon principle. The water heater is provided with a water inlet and outlet pipe, a one-way valve is arranged between a tee connected with the water inlet and outlet pipe and a reverse air inlet pipe, and a siphon bend is arranged in a heat-insulating layer at the outside of a water storage tank. After the water heater of the utility model is filled with water, the water in the water inlet and outlet pipe can be discharged, and the problem that the water inlet and outlet pipe of the solar water heater is easily frozen and cracked in winter is solved. The utility model is suitable for people in the northern areas of China to shower.

Description

A kind of four seasons type solar water heater

The utility model relates to the technology of utilizing of solar energy, a kind of specifically siphonic solar water heater.

The utility model is the improvement for 97215956.8 utility model patents.This utility model patent has solved the north of china in winter filler pipe, the drainpipe resident water freezes, the problem of the easy bursting by freezing of pipeline.But also there is a problem in this utility model, promptly when water in the water storage tank is expired, can cause siphon pipe and water inlet pipe flowing water simultaneously.In addition, this utility model patent has a U type trap in circuit design, makes the installment work complexity, and is time-consuming, effort.

The purpose of this utility model is to want to provide a kind of can utilize siphon principle, solves when water in the water storage tank is expired, and can cause siphon pipe and the water inlet pipe problem of flowing water simultaneously, solves problem time-consuming when installing, effort simultaneously.

The technical solution of the utility model is as follows: the utility model is designed to one with water inlet pipe and water outlet pipe, between threeway that connects water inlet pipe and water outlet pipe and reverse air inlet pipe a check valve is housed.The effect of this check valve is to allow air be entered in the water inlet pipe and water outlet pipe by the external world, and current are flowed out from reverse air inlet pipe.In heat-insulation layer, water inlet is in the water storage tank bottom with the siphon bend design for the utility model.The utility model also removes the water storage of U type, makes installation easier.

The utility model has the advantages that: because in the threeway of water inlet pipe and water outlet pipe with oppositely adorned a check valve between the air inlet pipe, thereby air can enter water inlet pipe and water outlet pipe by the external world, guarantees that water pipe does not freeze winter, and guarantee that current do not flow out from reverse air inlet pipe.The siphon bend design can reduce the heat loss when using hot water in heat-insulation layer.The utility model removes U type water storage elbow, makes when installing easier.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

As can be known from Fig. 1, the utility model mainly is made up of water storage tank 15, heat-insulation layer 7, glass evacuated endothermic tube 8, reverse air inlet pipe 1, check valve 2, water inlet pipe and water outlet pipe 3, overflow blast pipe 4, threeway 5, siphon bend 6 and

valve

10,11,12,13,14.In solar energy water storage tank 15 outsides one deck heat-insulation layer 7 is arranged, siphon bend 6 is contained in the heat-insulation layer 7 of water storage tank 15 outsides, and the intake-outlet of siphon bend 6 connects the threeway 5 of siphon bend 6 and oppositely between the air inlet pipe 1 check valve 2 arranged in water storage tank 15 bottoms.Overflow blast pipe 4 is contained in water storage tank 15 tops, oppositely on the air inlet pipeline valve 10 being housed,

valve

11,12,13,14 is housed on inlet and outlet pipe.Indicating 9 among the figure is building.

When the utility model uses, operate as follows:

1, open water supply valve door 11, make water inject water storage tank, fill it up with or adding enough water after, valve-off 11 is opened valve 12,10, at this moment, air with the water emptying in the water inlet pipe and water outlet pipe, guarantees that water pipe did not freeze during winter by valve 10 and check valve 2.

2, treat that water shines heat when using, open water supply valve door 11, add water in a few second, make water pipe fill with water, valve-off 10 is opened valve 12, and water flows out along water pipe under siphonage, when hand touched hot water, valve-off 12 cooperated shower valve 13,14 to regulate water temperature and uses.

When 3, used winter, valve 10,12 should often be opened, and kept anhydrous in the water pipe, and summer, 10,12 on valve can be normally closed when using.

Claims

1, a kind of four seasons type solar water heater comprises water storage tank, and heat-insulation layer, glass evacuated endothermic tube and water inlet pipe and water outlet pipe is characterized by, and water inlet pipe and water outlet pipe is one, connects the threeway of water inlet pipe and water outlet pipe and oppositely between the air inlet pipe check valve is housed; Siphon bend is contained in the heat-insulation layer of water storage tank outside, and the intake-outlet of siphon bend is in the water storage tank bottom.
