Abstract

The utility model relates to a solar water heater which is composed of a solar heat collection and water heating system, an inner pipeline and an outer pipeline, wherein the inner pipeline adopts the structure that one end of a water circulating pipe is communicated with the bottom of a water storage box, the other end of the water circulating pipe is connected with a water return box through a unidirectional check valve, the water return box is communicated with the water storage box through a water return pipe, a switch of the water return pipe is controlled by a ball float installed in the water storage box 1, and a safety valve is installed on the water return pipe. The solar water heater of the utility model can realize circulation between water in the water pipe and water in the water storage box so as to guarantee the cleanness of the water in the pipelines; besides, as the water in the heater realizes thermal cycling, when the utility model needs using, hot water flows out just through opening the valve, a user does not need to wait, and thus, water resources and time are saved.

Description

Solar water heater

Technical field

The utility model relates to a kind of, particularly a kind of solar water heater.

Background technology

Same water pipe all adopted in water inlet, the water outlet of the solar water heater on the domestic market at present, this Inlet and outlet water mode can cause the generation of following shortcoming: 1. because not circulation between water in the water pipe and the water in the water storage tank, so the water in the water pipe is cold water, just can use the hot water in the water storage tank after before having a bath, it must being drained, cause waste water resource; 2. because the water in the water pipe is inactive state, thereby easily produce bacterium when water heater is not worked, influence the cleaning of water pipe, the health of harmful to human; 3. the steam vent that is used in common drowning type and the automatic water supplement type water heater on the market also can cause the loss of a part of heat.

Summary of the invention

The purpose of this utility model is to provide a kind of solar water heater, and it has characteristics energy-conservation, water saving.

The purpose of this utility model is achieved through the following channels: solar water heater, it is adopted heat up water system, internal duct and exterior line of heat by solar energy and forms, and exterior line wherein comprises: the inlet pipeline of forming by the water inlet pipe 14 of communication loop water pipe 10, by the electromagnetic water inlet valve 6 that is installed in level sensor 9 controls on the circulating water pipe 10, mix cold water pipeline, outlet valve 11, outlet pipe 13 and pouring 12 outlet pipeline of forming by the communication loop water pipe by what cold valves 7 and water inlet divided that branching pipe 15 forms; The structure of internal duct is as follows: an end of circulating water pipe 10 is communicated with the bottom of water storage tank 8, the other end is connected with recovery tank 1 through one way stop peturn valve 5, this recovery tank 1 is communicated with water storage tank 8 by return pipe 16, and the switch of return pipe 16 is by ball-cock assembly 6 controls of installing in the recovery tank 1.One safety valve 3 is installed on the return pipe 16.

The utility model solar water appliance has following characteristics:

1. can realize the circulation between the water in water and the water storage tank in the water pipe, the cleaning of water quality in the assurance pipeline;

2. because the water in the water heater has been realized thermal cycle, only need open valve during use just has hot water to flow out, and need not to wait for, has not only saved water resource but also saved the time.

Description of drawings

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

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

The specific embodiment

As shown in Figure 1, the utility model solar water heater, it is adopted heat up water system, internal duct and exterior line of heat by solar energy and forms, and exterior line wherein comprises: the inlet pipeline of forming by the water inlet pipe 14 of communication loop water pipe 10, by the electromagnetic water inlet valve 6 that is installed in level sensor 9 controls on the circulating water pipe 10, mix cold water pipeline, outlet valve 11, outlet pipe 13 and pouring 12 outlet pipeline of forming by the communication loop water pipe by what cold valves 7 and water inlet divided that branching pipe 15 forms;

The structure of internal duct is as follows: an end of circulating water pipe 10 is communicated with the bottom of water storage tank 8, the other end is connected with recovery tank 1 through one way stop peturn valve 5, this recovery tank 1 is communicated with water storage tank 8 by return pipe 16, the switch of return pipe 16 is by ball-cock assembly 6 controls of installing in the recovery tank 1, in order to guarantee the safety of water storage tank, a safety valve 3 is installed on return pipe 16.In winter, can assist heating by the incoming call formula electric heater 4 that is installed in the water storage tank 8.

The operation principle of this water heater water circulation is such: solar energy is adopted the heat system works of heating up water, utilize the heat that absorbs solar energy that the cold water in the case is heated, the cold water that the heat that hot water after heating up in the water storage tank 8 distributes produces in case in the pressure promotion circulating water pipe 10 enters recovery tank 1, ball-cock assembly 2 is opened the passage between return pipe 16 and the water storage tank 8 automatically after the water level of recovery tank 1 raises, cold water in the circulating water pipe 10 enters water storage tank 8, thereby finishes whole water circulation.

The water that is consumed when having a bath replenishes by opening electromagnetic water inlet valve 6 automatically after level sensor 9 perception.

Claims
