Description

Solar water heater with automatic emptying system

technical field

The utility model relates to a solar water heater equipped with an automatic emptying system, which belongs to the technical field of solar water heaters.

Background technique

Solar water heaters are water heaters heated by solar energy. They are popular because of their cleanliness and economy. Solar water heaters are generally installed on high places in buildings, and are connected to users' water facilities through the upper and lower water pipes. Since there is always water in the upper and lower water pipes, and the stored water will cool down quickly, users must put cold water before use. Therefore, existing solar water heaters have the following disadvantages: 1. waste of water resources; Pipeline repairs are very expensive.

In the existing technology, the commonly used solution is to install an electric heating belt and an insulating layer on the exposed upper and lower water pipes, and melt the ice in the upper and lower water pipes by means of electric heating. This method consumes a lot of energy, costs high, and the effect is not ideal. It is also prone to disadvantages such as electric heating leakage and fire, and there are potential safety hazards.

Utility model content

The purpose of this utility model is to provide a solar water heater equipped with an automatic emptying system to solve the above technical problems.

In order to solve the above problems, the technical solution adopted in the utility model is:

A solar water heater equipped with an automatic emptying system, including a heat collecting device, a water storage tank and an upper and lower water pipeline, the water storage tank includes an outer shell, an inner tank and an insulation layer arranged between the outer shell and the inner tank, and the top of the water storage tank There is an exhaust pipe connected to the inner tank; it is characterized in that: the top of the upper and lower water pipes runs through the insulation layer upwards, and extends into the inner tank from the top of the inner tank, and is fixedly connected to the anti-air pipe at its port, and the anti-air pipe The port is close to the bottom of the liner, and its inner diameter is greater than the inner diameter of the upper and lower water pipes; the bottom ends of the upper and lower water pipes are respectively connected to the water-air conversion box and the upper water pipe through the three-way pipe joint, and the upper water pipe is equipped with an upper water pipe. The water valve is connected with the tap water pipeline; the water-air conversion box is provided with a slow-flow sound-reducing plate arranged obliquely. position; the water-air conversion box is provided with an air intake pipe, and the outer end of the air intake pipe passes through the water-air conversion box, and an air intake control valve is installed; the water-air conversion box is connected with the water mixing valve through a pipeline.

Beneficial effects: due to the adoption of the above-mentioned technical scheme, the utility model can not only completely solve the problems of wasting water resources of the existing solar water heaters and freezing and blocking the upper and lower water pipes when used in winter, but also does not need to install electric heating belts and insulation layers, Low energy consumption, low cost, and safe use.

Description of drawings

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

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Referring to Fig. 1, the solar water heater equipped with an automatic emptying system according to the utility model includes a heat collecting device, a water storage tank and an upper and lower water pipeline 2, and the water storage tank includes a shell 10, an inner tank 12 and is located between the outer shell 10 and the inner tank 12. There is an insulating layer 11 between them, and the top of the water storage tank is provided with an exhaust pipe 13 communicating with the inner tank 12 .

The top of the upper and lower water pipes 2 runs through the insulation layer 11 upwards, and extends into the inner tank 12 from the top of the inner tank 12, and is fixedly connected to the anti-air pipe 1 at its port, and the port of the anti-air pipe 1 is close to the bottom of the inner tank 12 , its inner diameter is greater than the inner diameter of the upper and lower water pipes 2; the bottom of the upper and lower water pipes 2 are respectively connected to the water-air conversion box 4 and the upper water pipe 14 through a three-way pipe joint, and the upper water pipe 14 is equipped with a water inlet valve 6, and connected with the tap water pipeline 7; the water-air conversion box 4 is provided with a slow-flow sound-reducing plate 3 inclined to be arranged, and the slow-flow sound-reducing plate 3 is located at the bottom port of the upper and lower water pipes 2 and is connected with the water-gas conversion The position where the box 4 is connected; the water-air conversion box 4 is provided with an air intake pipe 9, and the outer end of the air intake pipe 9 passes through the water-air conversion box 4, and an air intake control valve 5 is installed; the water-air conversion box 4 is connected with mixing valve 8 by pipeline.

The principle of the solar water heater described in the utility model:

After installation as shown in Figure 1, open the water supply valve 6, the tap water in the tap water pipe 7 passes through the upper and lower water pipes 2, enters the inner tank 12 from the anti-air pipe 1, and when the water is full, the overflowing water returns to the water through the exhaust pipe 13 When indoors, close the upper water valve 6, at this time, the water in the upper and lower water pipes 2 flows slowly into the water-gas conversion box 4 due to gravity, and the air in the water-gas conversion box 4 flows slowly along the upper and lower water pipes 2 simultaneously. Upward, all the water in the upper and lower water pipes 2 are replaced in the water-gas conversion box 4, so as to achieve the purpose of emptying the upper and lower water pipes 2. When using hot water, open the water mixing valve 8, and the water in the water-air conversion box 4 flows out. According to the siphon principle, the hot water in the inner tank 12 is drained by the anti-air pipe 1, through the upper and lower water pipes 2, and through the slow-flow sound-reducing board 3 is buffered and enters the water-air conversion box 4, and then sent to the hot water bathing facility through the water mixing valve 8.
