Description

Technical Field

[0001] This utility model relates to the field of solar water supply technology, and in particular to an automatic water supply device for a solar water heater. Background Technology

[0002] Solar energy is a clean energy source that has been widely used. Among the widely used methods, solar water heaters utilize solar collector tubes to convert solar radiation into heat energy to heat the water inside the collector tubes. The heated water is then supplied to users, thus realizing the utilization of solar energy.

[0003] During this process, water needs to be supplied to the solar water heater. Room temperature water is introduced into the solar water heater's collector tubes and manifold. The collector tubes heat the water inside, and the density of the heated water decreases, causing it to rise to the top manifold. At the same time, the cold water in the manifold descends into the collector tubes, achieving all-round heating of the water. After the water is heated, a drain hole is opened at the bottom of the collector tubes, and the water is transported indoors for use with the help of valves and pipes.

[0004] However, since solar water heaters are usually installed in open areas such as rooftops, the presence or absence of water in the water heater and the start / stop of the water pump need to be manually checked during water supply, resulting in low water supply efficiency, water supply effect, and water supply convenience.

[0005] The aforementioned patent has the following shortcomings:

[0006] Therefore, an automatic water supply device for solar water heaters is proposed. Utility Model Content

[0007] In view of this, the present invention aims to provide an automatic water supply device for solar water heaters to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0008] The technical solution of this utility model embodiment is implemented as follows: an automatic water supply device for a solar water heater includes an inlet pipe connected to the inlet of a manifold, a water pump connected to the other end of the inlet pipe, and a water storage device connected to the inlet side of the water pump. The automatic water supply device includes a processing chip installed on the bracket of the solar water heater or indoors / outdoors of the user, and a liquid level sensor installed at the bottom of one of the collector tubes of the solar water heater. The liquid level sensor is electrically connected to the processing chip, and the processing chip is connected to the water pump control.

[0009] In some embodiments, a support ring is fixed inside the stop of the water inlet pipe, and a first hollow frame and a second hollow frame are respectively provided on both sides of the support ring. A first filter membrane is fixed inside the hollow part of the first hollow frame, and a second filter membrane is fixed outside the hollow part of the second hollow frame.

[0011] In some embodiments, the second hollow frame is rotatably connected to the bottom of the support ring, and the first hollow frame is rotatably connected to the top of the support ring.

[0012] In some embodiments, a turbine blade is fixed to the inner wall of the hollow frame 2, and a main shaft is fixed to the top of the turbine blade.

[0013] In some embodiments, the outer wall of the main shaft is fixed with bristles one that contact and cooperate with filter membrane one, and the inner wall of the water inlet pipe is fixed with bristles two that contact and cooperate with filter membrane two.

[0014] In some embodiments, a pressure sensor is installed on the side wall of the water inlet and the side wall of the water inlet pipe, respectively, and the pressure sensor is electrically connected to the processing chip.

Detailed Implementation

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.

"Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1:

[0033] like Figure 1-5 As shown, an automatic water supply device for a solar water heater includes an inlet pipe 3 connected to the inlet 2 of a manifold 1. The manifold 1 is installed on the bracket of the solar water heater and is connected to the collector pipe of the solar water heater to form a relatively closed water storage chamber. The other end of the inlet pipe 3 is connected to a water pump 15, and the inlet side of the water pump 15 is connected to a water storage device.

[0034] In this embodiment, the water storage device is not specifically limited. When tap water is supplied uniformly, the water storage device is a tap water pipe. When a well can be used for water supply, the water storage device is a well. Or, when there are water storage tanks or reservoirs, the water storage device is a water storage tank or reservoir. In short, the purpose of the water storage device is to provide a water source. This is existing technology and is common knowledge for those skilled in the art. This embodiment will not elaborate on it.

[0035] The automatic water supply device includes a processing chip 14 installed on the bracket of the solar water heater or indoors / outdoors of the user, and a liquid level sensor 16 installed at the bottom of one of the heat collection tubes of the solar water heater. The liquid level sensor 16 is electrically connected to the processing chip 14, and the processing chip 14 is controlled by the water pump 15.

[0036] When this device is in use, the liquid level sensor 16 can sense the liquid level height of the relatively closed inner cavity formed by the manifold 1 and the heat collection tube. The upper and lower limits of the liquid level height can be set by the processing chip 14. When the liquid level drops to the lower limit, the processing chip 14 receives the liquid level signal and controls the water pump 15 to start. The water pump 15 draws water through the water storage device and inputs it into the manifold 1 through the water inlet pipe 3 and the water inlet 2 until the liquid level inside reaches the upper limit. Then, the processing chip 14 receives the liquid level signal and controls the water pump 15 to shut down.

[0037] This device, by incorporating components such as a processing chip 14, a water pump 15, and a liquid level sensor 16, can automatically supply water and automatically stop water supply based on the set upper and lower limits of the liquid level, thereby improving water supply efficiency, water supply effect, and water supply convenience.

[0038] Example 2:

[0039] An automatic water supply device for a solar water heater is provided in this embodiment, which is improved upon embodiment 1 as follows: Figure 1-5 As shown, a support ring 6 is fixed inside the stop of the water inlet pipe 3. A hollow frame 4 and a hollow frame 7 are respectively provided on both sides of the support ring 6. A filter membrane 5 is fixed inside the hollow part of the hollow frame 4, and a filter membrane 8 is fixed outside the hollow part of the hollow frame 7.

[0040] In this embodiment, filter membrane 5 is an RO reverse osmosis membrane, and filter membrane 8 is a cotton textile filter membrane.

[0041] When the device is in use, the water source flows upward from the bottom of the inlet pipe 3 and passes through filter membrane 2 8 and filter membrane 1 5 in sequence. After being filtered by filter membrane 1 5 and filter membrane 2 8, the water enters the hollow frame 1 4.

[0042] This device, by setting filter membrane 5 and filter membrane 8, can filter the water entering the collector tube and manifold 1, thereby preventing impurities in the water from entering and causing damage. In addition, by setting filter membrane 5 as an RO reverse osmosis membrane, it can filter calcium and magnesium ions in the water, thereby preventing scale from forming after the water cup is heated, and increasing the reliability of use.

[0043] In this embodiment, the second hollow frame 7 is rotatably connected to the bottom of the support ring 6, and the first hollow frame 4 is rotatably connected to the top of the support ring 6.

[0044] In this embodiment, a turbine blade 11 is fixed to the inner wall of the hollow frame 7, and a main shaft 10 is fixed to the top of the turbine blade 11.

[0045] In this embodiment, the outer wall of the main shaft 10 is fixed with bristles 9 that contact and cooperate with the filter membrane 5, and the inner wall of the water inlet pipe 3 is fixed with bristles 12 that contact and cooperate with the filter membrane 8.

[0046] A pressure sensor 13 is installed on the side wall of the water inlet 2 and the side wall of the water inlet pipe 3 respectively, and the pressure sensor 13 is electrically connected to the processing chip 14.

[0047] The pressure sensor 13 can monitor the pressure difference of the water source before and after filtration, thereby using the pressure difference to monitor the clogging of filter membrane 5 and filter membrane 8. At the same time, it can also adjust the water delivery speed of the water pump 15 according to the pressure difference to prevent the filter membrane 5 and filter membrane 8 from being torn by excessive water pressure due to excessive flow rate, and to prevent the water supply speed from being slow due to slow filtration speed.

[0048] Brush bristles 19 are soft bristles. They will not damage filter membrane 5.

[0049] When the water flows upward from the hollow frame 2 7, it impacts the turbine blade 11, causing the turbine blade 11 to drive the hollow frame 2 7 to rotate, which in turn causes the main shaft 10 to drive the brush bristles 1 9 to rotate. Since the hollow frame 1 4 is fixed, the brush bristles 1 9 sweep against the filter membrane 1 5, while the brush bristles 2 1 2 remain stationary. The rotation of the hollow frame 2 7 allows the brush bristles 2 1 2 to sweep against the filter membrane 2 8.

[0050] This device, by setting up brush bristles 9 and brush bristles 12, can sweep and clean filter membrane 5 and filter membrane 8 respectively, thereby preventing clogging. At the same time, its sweeping power comes from water flow, thus saving power and facilitating volume optimization.

[0051] In this embodiment: when the water source flows upward from the bottom of the inlet pipe 3, it will pass through the filter membrane 2 8 and the filter membrane 1 5 in sequence. The filter membrane 1 5 and the filter membrane 2 8 filter the water before it enters the hollow frame 1 4. In addition, when the water flows upward from inside the hollow frame 2 7, it will impact the turbine blade 11, which will cause the turbine blade 11 to drive the hollow frame 2 7 to rotate, which will cause the main shaft 10 to drive the brush bristles 1 9 to rotate. Since the hollow frame 1 4 is fixed, the brush bristles 1 9 will sweep the filter membrane 1 5. At the same time, the brush bristles 2 12 are stationary. The rotation of the hollow frame 2 7 will cause the brush bristles 2 1 2 to sweep the filter membrane 2 8.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
