Description

Technical Field

[0001] This utility model belongs to the field of solar water heating technology, specifically relating to a solar water heating device. Background Technology

[0002] With the rapid development of technology and the increasing number of electrical appliances in our lives, most apartments have begun to use solar energy to provide hot water. Solar water heaters heat water by absorbing solar energy, have low energy consumption, and have a very high adoption rate. However, when used in winter, the temperature of solar water is too low, so it cannot be used directly for bathing or other purposes, resulting in the solar water heater not being used effectively.

[0003] For example, in the Chinese utility model patent CN203771724U entitled "A Heat Pump Compensated Solar Water Heater Supply Device", the above-mentioned technology uses a heat pump to heat the water in the first and second hot water storage tanks, thereby increasing the hot water temperature and improving the utilization rate of hot water. However, due to the pressure difference between the hot and cold water, the fixed-position heating may cause local overheating or undercooling, resulting in a large temperature difference between the hot and cold water, which will cause a poor user experience. Therefore, a solar water heater supply device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a solar water heating supply device with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A solar water heating supply device includes a support frame, a water tank fixedly mounted on the top surface of the support frame, a municipal water inlet pipe fixedly connected to one side of the water tank, a plurality of vacuum collectors fixedly mounted on both sides of the support frame, one end of each vacuum collector passing through the support frame and fixedly connected to the water tank, a water inlet pipe fixedly connected to the other side of the water tank, a water storage tank disposed on one side of the water tank, an inner tank disposed inside the water storage tank, a pressure pump disposed on the water inlet pipe, one end of the water inlet pipe passing through the water storage tank and fixedly connected to the inner tank, a stirring assembly disposed inside the inner tank, and a water outlet pipe connected to the inner tank disposed on one side of the water storage tank.

[0007] As a further optimization of this utility model, the stirring assembly includes a servo motor fixedly connected to the top of the water storage tank, the output end of the servo motor is fixedly connected to a hollow shaft located inside the inner liner, scrapers are fixedly connected to both sides of the surface of the hollow shaft, and electric heating tubes are provided on both sides of the surface of the hollow shaft.

[0008] As a further optimization of this utility model, an adapter is fixedly installed at the bottom of the water storage tank, and one end of the adapter is rotatably connected to the hollow shaft.

[0009] As a further optimization of this utility model, the top of the water storage tank is provided with an air outlet that is fixedly connected to the inner liner. A push rod is provided inside the air outlet, and a suspended ball is fixedly connected to the top of the push rod. A spring is fixedly provided on the inner wall of the air outlet, and the other end of the spring is fixedly installed with the suspended ball. The bottom of the push rod is a conical surface.

[0010] As a further optimization of this utility model, reflectors are fixedly installed on both sides of the inner wall of the bracket, the reflectors are located on the back of several vacuum collectors, and a temperature sensor that cooperates with the inner tank is provided on the top of the water storage tank.

[0011] As a further optimization of this utility model, a drain pipe communicating with the inner liner is provided on one side of the water storage tank, a valve is provided on the drain pipe, and a solenoid valve is provided on the water outlet pipe.

[0012] The beneficial effects of this utility model are as follows: By installing an inner tank inside the water storage tank, and a stirring component inside the inner tank, a vacuum state is created using the gap between the water storage tank and the inner tank. This prevents heat loss through heat conduction, improving the insulation effect inside the inner tank. Then, through a servo motor, hollow shaft, scraper, and electric heating element, when there is residual warm water in the inner tank, a pressure pump sends hot water into the inner tank through the inlet pipe. The servo motor drives the hollow shaft to rotate, and the scraper and electric heating element rotate simultaneously in the water, ensuring thorough mixing of warm and hot water and preventing localized overheating. The cooling process makes the water temperature inside the tank more uniform. Then, the electric heating element is activated. When the scraper and the electric heating element rotate, it promotes water convection, accelerates the water flow, and makes the water contact the surface of the electric heating element more frequently, significantly improving the heat transfer efficiency. This allows the water to be heated faster, continuously contacting and exchanging heat with water in different locations, thus raising the water temperature. When the inside of the tank needs cleaning, the electric heating element can be turned off, and the servo motor drives the scraper to rotate, scraping off the scale on the inner wall of the tank. The scale-containing water is then discharged from the tank through the drain pipe. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 and Figure 3As shown, a solar water heating supply device includes a support frame 1. A water tank 2 is fixedly installed on the top surface of the support frame 1. A municipal water inlet pipe 4 is fixedly connected to one side of the water tank 2. In use, the municipal water inlet pipe 4 introduces water from the city's water supply system into the specific building area. Several vacuum collectors 3 are fixedly installed on both sides of the support frame 1. One end of each vacuum collector 3 passes through the support frame 1 and is fixedly connected to the water tank 2. In use, it can effectively absorb solar energy, convert the collected solar energy into heat energy, and then use it to heat water or other heat transfer media, thereby achieving heat transfer. The method involves heating the cold water inside the water tank 2. Reflectors 20 are fixedly installed on both sides of the inner wall of the support 1, located behind several vacuum collectors 3. During use, the reflectors 20 reflect sunlight onto the vacuum collectors 3, allowing them to receive more solar energy, thus improving heat collection efficiency and accelerating the water's heating rate. A water inlet pipe 5 is fixedly connected to the other side of the water tank 2. A water storage tank 7 is installed on one side of the water tank 2, with an inner liner 10 inside. During use, the water storage tank 7 and the inner liner 10 are in a vacuum... In an empty state, to prevent heat loss through heat transfer, the inner tank 10 has a certain heat preservation performance, which can reduce heat loss and keep the stored hot water at a certain temperature for a longer period of time. A pressure pump 6 is installed on the inlet pipe 5. During use, the pressure pump 6 applies pressure to the hot water inside the water tank 2, increasing the pressure of the hot water and making the hot water flow faster in the inlet pipe 5, thereby increasing the flow rate of hot water and allowing hot water to enter the inner tank 10. One end of the inlet pipe 5 passes through the water storage tank 7 and is fixedly connected to the inner tank 10. A connection between the water storage tank 7 and the inner tank is provided on one side. The water outlet pipe 9, connected to the inner tank 10, has a filter screen (not shown in the diagram) between it and the inner tank 10 during use. This prevents scale from being carried out by the hot water as it flows out of the outlet pipe 9, ensuring the cleanliness of the hot water and improving the user's comfort. The outlet pipe 9 is equipped with a solenoid valve 19, which can be opened or closed according to an electrical signal to control the flow of hot water from the inner tank 10. When hot water is needed, it flows out from the outlet pipe 9; when water is not needed, the solenoid valve is closed to prevent the hot water from flowing out and avoid wasting hot water.

[0021] like Figure 2 and Figure 3As shown, an agitator 8 is installed inside the inner tank 10, and a temperature sensor 16, which works in conjunction with the inner tank 10, is installed on the top of the water storage tank 7. During use, the temperature sensor 16 can detect the temperature of the hot water in the inner tank 10 in real time. Based on the water temperature information provided by the temperature sensor 16, users can better plan their water usage time and method. The agitator 8 includes a servo motor 801 fixedly connected to the top of the water storage tank 7. The output end of the servo motor 801 is fixedly connected to a hollow shaft 802 located inside the inner tank 10. During use, the servo motor 801 acts as a power source, and its output end drives the hollow shaft 802 to rotate within the inner tank 10. An adapter 11 is fixedly installed at the bottom of the water storage tank 7. One end of the adapter 11 is rotatably connected to the hollow shaft 802. During use, the wire is electrically connected to the adapter 11. The adapter 11 is rotatably connected inside the hollow shaft 802, preventing the wire from interfering with other parts. To address the issue of parts becoming entangled, scrapers 803 are fixedly connected to both sides of the hollow shaft 802. During use, one of the scrapers 803 is C-shaped. When the servo motor 801 drives the scraper 803 to rotate, the scraper 803 will rotate along the inner wall of the inner tank 10. Electric heating tubes 804 are installed on both sides of the hollow shaft 802. During use, when hot water is needed, the electric heating tubes 804 can quickly work, converting electrical energy into heat energy and transferring it to the surrounding water, causing the water temperature to rise rapidly. The adapter 11 is electrically connected to the electric heating tubes 804. A drain pipe 17 connected to the inner tank 10 is installed on one side of the water storage tank 7. A valve 18 is installed on the drain pipe 17. During use, when the servo motor 801 drives the scraper 803 to remove scale from the inner wall of the inner tank 10, opening the valve 18 allows the water containing scale to be discharged to the outside of the inner tank 10 through the drain pipe 17, ensuring the cleanliness of the water inside the inner tank 10.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the top of the water storage tank 7 is equipped with a vent 12 that is fixedly connected to the inner tank 10. During use, when water is heated, it vaporizes into steam, generating pressure. The vent 12 can promptly release the generated steam to prevent excessive internal pressure. A push rod 13 is installed inside the vent 12, with a suspended ball 14 fixedly connected to the top of the push rod 13. A spring 15 is fixedly installed on the inner wall of the vent 12, with the other end of the spring 15 fixedly installed to the suspended ball 14. The bottom of the push rod 13 is a conical surface. During use, when the internal steam pressure increases... When the steam is high, it pushes the suspended ball 14 upward, stretching the spring 15 and raising the suspended ball 14 to a certain height, thereby opening a larger steam outlet and allowing more steam to escape, thus reducing the internal pressure. When the pressure decreases, the spring 15 returns to its elasticity, pushing the suspended ball 14 downward, reducing the opening of the steam outlet and reducing the amount of steam discharged. When the electric heating tube 804 rotates to heat the water, the scraper 803 reciprocates to press the push rod 13, causing the push rod 13 to slide upward, thereby driving the suspended ball 14 to move upward, so that steam can also be discharged during the heating process.

[0023] It should be noted that in the operation of this solar water heating device, water is first supplied to the water tank 2 through the municipal water inlet pipe 4. At this time, the reflector 20 and vacuum collector 3 convert solar energy into heat energy, thereby heating the water inside the water tank 2. The heated water is pressurized by the pressure pump 6, causing the hot water to flow rapidly through the inlet pipe 5. The flowing hot water enters the inner tank 10 inside the storage tank. Because the inner tank 10 and the storage tank 7 are in a vacuum state, the hot water is prevented from being lost through heat transfer, ensuring that the stored hot water maintains a certain temperature for a relatively long period. When the user needs hot water, the outlet pipe 9 is opened through the solenoid valve 19, allowing the user to use hot water. If the water supply becomes insufficient after a period of use, the temperature sensor 16 detects that the internal water temperature is below standard. Water is then supplied to the water tank 2 through the municipal water inlet pipe 4, where it is heated. The pressure pump 6 then supplies the hot water into the inner tank 10, which now contains both warm and hot water. The servo motor is then activated. 801. The servo motor 801 rotates, driving the hollow shaft 802, scraper 803, and electric heating element 804 to rotate. The rotation of scraper 803 ensures thorough mixing of warm and hot water, preventing localized overheating and undercooling. Simultaneously, the electric heating element 804 is activated. The rotation of scraper 803 and electric heating element 804 increases the water flow rate, expanding the contact area between the water and the heating element, thus improving heat transfer efficiency and raising the temperature of the mixed water. This is then controlled by solenoid valve 19, which opens the outlet pipe 9. The system is open to continue providing hot water to the user. After the inner tank 10 has been heated for a period of time, scale will be generated to clean the inner tank 10. At this time, the municipal water inlet pipe 4 and the booster pump will supply water to the inner tank 10. Then, the electric heating element 804 will be turned off. Then, the servo motor 801 will drive the scraper 803 to rotate. The scraper 803 will contact the inner wall of the inner tank 10 and scrape off the scale on the inner wall when it rotates. Then, the valve on the drain pipe 17 will be opened to discharge the water containing scale to the outside of the inner tank.

[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
