Description

Technical Field

[0001] This utility model relates to the field of solar water heaters, and in particular to an intelligent constant temperature water supply control system for independent ground solar water heaters. Background Technology

[0002] Solar water heaters, with their core advantages of being clean, energy-efficient, and having low operating costs, have become an important component of rural energy structure upgrading, effectively improving hot water supply conditions for farmers and reducing environmental pollution caused by fossil fuel consumption. However, existing technologies still suffer from two major pain points in practical applications, severely limiting their applicability and user experience.

[0003] Firstly, the intelligent adjustment capability is insufficient, resulting in poor temperature control. Currently, most mainstream vacuum tube solar water heaters rely on manual adjustment of the hot and cold water ratio to control the outlet water temperature. Affected by fluctuations in sunlight intensity, the water temperature in the hot water tank is prone to extreme changes (such as the water temperature often exceeding 90℃ at noon), making it difficult to accurately control the mixing ratio of hot and cold water. The outlet water temperature fluctuation can reach ±5℃ or more, which not only affects the comfort of use but also poses a risk of scalding due to excessively high water temperature or a sudden drop in water temperature due to uneven mixing, failing to meet the needs of normal bathing, agricultural cleaning, etc.

[0004] Secondly, installation is limited by specific conditions and applicable scenarios. Traditional solar water heaters require fixed installation on rooftops and rely on stable water pressure from municipal tap water or elevated water tanks for replenishment and supply. In remote rural areas, some farmhouses lack suitable rooftop installation space; in agricultural settings such as vegetable greenhouses and vineyards, rooftop installation is lacking and water usage points are scattered; in mobile or temporary scenarios such as temporary construction sites and inland waterway transport vessels, there is neither a fixed installation foundation nor a stable water pressure supply, making it difficult to promote the application of traditional solar water heaters. The hot water demand in these scenarios still relies on high-energy-consuming methods such as electric heating and oil heating, which contradicts the development trend of energy conservation and emission reduction.

[0005] Therefore, developing a solar water heater system that can be independently installed on the ground, requires no external power supply or stable water pressure, and can accurately control the outlet water temperature, is of great practical significance for promoting the popularization and application of solar thermal utilization technology. It is also a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an independent ground solar water heater intelligent constant temperature water supply control system, which enables independent ground installation, eliminates the need for external power supply and stable water pressure, and can accurately control the outlet water temperature, thereby overcoming the shortcomings of the existing system.

[0007] To solve the above-mentioned technical problems, this utility model provides an intelligent constant temperature water supply control system for an independent ground solar water heater, including a cold water storage tank, a mixing tank, a hot water collection tank, a water supply booster pump, a mixing solenoid valve, a hot water booster circulation pump, a hot water flow sensor, a constant temperature outlet water temperature sensor, and an intelligent controller. The cold water storage tank stores cold water, which is connected to the mixing tank via pipelines through a water booster pump and a mixing solenoid valve. The hot water tank is integrated with the heat collection pipe, stores hot water inside, and is connected to the mixing tank through a pipeline and a hot water booster circulation pump. The mixing tank is connected to the hot water tap and shower head through pipelines, and a hot water flow sensor and a constant temperature outlet water sensor are installed on the pipelines. The water booster pump, mixing solenoid valve, hot water booster circulation pump, hot water flow sensor, and constant temperature outlet water temperature sensor are all electrically connected to the intelligent controller via control lines. The intelligent controller controls the opening and closing of the water booster pump, mixing solenoid valve, and hot water booster circulation pump based on the signals from the hot water flow sensor and the constant temperature outlet water temperature sensor, thereby achieving real-time mixing of hot and cold water.

[0008] As an improvement of this utility model, the water booster pump is connected to the hot water collection tank in sequence via a water solenoid valve and a water pipe. The water supply pipe is provided with a branch line connected to the mixing tank, and a circulation solenoid valve is installed on the branch line; The hot water collection tank is equipped with a water level sensor and a hot water collection tank temperature sensor, and the mixing water tank is equipped with a mixing water tank temperature sensor. The water level sensor, the hot water collection tank temperature sensor, the mixing water tank temperature sensor, the water inlet solenoid valve, and the circulation solenoid valve are all electrically connected to the intelligent controller. The intelligent controller controls the opening and closing of the water supply booster pump and the water supply solenoid valve based on the water level signal from the water level sensor, in order to replenish water to the hot water collection tank. The intelligent controller controls the opening and closing of the hot water booster pump and the circulation solenoid valve based on the temperature signal difference between the temperature sensor of the hot water collection tank and the temperature sensor of the mixing tank, so as to circulate the hot water in the hot water collection tank and the warm water in the mixing tank to maintain the water temperature in the mixing tank.

[0009] Furthermore, a cold water flow sensor is also installed after the water booster pump.

[0010] Furthermore, an electric heating element is installed inside the mixing tank, and a pipe antifreeze temperature sensor is installed on the water supply pipe.

[0011] Furthermore, the aforementioned intelligent constant temperature water supply control system for an independent ground solar water heater also includes a solar panel, a solar panel controller, and a battery. The solar panel is installed on the outside front of the hot water tank to convert solar energy into electrical energy. The solar panel is electrically connected to the solar panel controller through an output line, and the solar panel controller is then electrically connected to the smart controller and the battery.

[0012] Furthermore, the hot water tank and the heat collection pipe are integrated and installed on the support frame, and the bottom of the support frame is equipped with wheels and placed inside a cement turntable.

[0013] Furthermore, the top of the hot water tank is provided with an exhaust vent.

[0014] Furthermore, the mixing tank is externally wrapped with a polyurethane insulation layer.

[0015] With this design, the present invention has at least the following advantages.

[0016] 1. This utility model uses an intelligent controller to turn on the hot water booster circulation pump to introduce hot water into the mixing tank when the outlet water temperature is lower than the set value, and to turn off the hot water booster circulation pump and turn on the water supply booster pump and mixing solenoid valve to inject cold water into the mixing tank when the outlet water temperature is higher than the preset value, so as to achieve real-time mixing of hot and cold water and maintain constant temperature outlet water.

[0017] 2. A branch line is installed on the water supply pipe of the hot water collection tank, which is connected to the mixing tank via a circulation solenoid valve. When the temperature difference between the hot water collection tank and the mixing tank is greater than the preset value, the circulation solenoid valve and the hot water booster circulation pump are turned on. At this time, the water supply solenoid valve is in the closed state. The water supply pipe and the hot water pipe form a circulation loop between the hot water collection tank and the mixing tank. The circulation of hot and warm water can maintain the water temperature in the mixing tank on the one hand, and prevent the pipes from freezing on the other hand.

[0018] 3. A solar panel is installed on the front of the hot water tank and is electrically connected to the solar panel controller. The solar panel controller is then electrically connected to the smart controller and the battery. It generates electricity using solar energy and stores it in the battery for use at night, thus achieving self-powered operation without the need for an external power source.

[0019] 4. The hot water tank and heat collection pipes are integrated and installed on the support frame, which is placed on a cement turntable slightly above the ground. It is suitable for rural areas, agricultural production sites (vegetable greenhouses, vineyards, farms, fish ponds), temporary buildings (construction sites), and mobile carriers (inland waterway transport vessels) and other non-roofed installation environments without stable water pressure. The support frame is equipped with four wheels at the bottom, which can be adjusted to improve the solar energy utilization rate. Attached Figure Description

Detailed Implementation

[0023] Please see Figure 1 This utility model provides an intelligent constant temperature water supply control system for an independent ground solar water heater, including a heat storage and water storage unit, an intelligent control unit, a power supply unit, and an adjustable installation unit.

[0024] The thermal and water storage unit includes a cold water storage tank 28, a hot water collection tank 5, and a mixing tank 20.

[0025] The cold water storage tank 28 is used to store cold water and has a cold water outlet 27 at the bottom.

[0026] The hot water tank 5 is integrated with the heat collection tube 29 and is used to store the hot water heated by the heat collection tube 29. It has an exhaust hole 34 on the top, a water inlet 7 on the side, and a hot water outlet 6 at the bottom.

[0027] The mixing tank 20 is used to store warm water. It is wrapped with a polyurethane insulation layer 21 on the outside, with a cold water inlet 22 at the bottom, a cold water nozzle 19 at the top inside, and a hot water inlet 15, a constant temperature outlet 10, and a circulating heating outlet 41 on the side.

[0028] The intelligent control unit includes an intelligent controller 1, an actuator, and a data acquisition element.

[0029] The specific actuators include a water booster pump 26, a hot water booster circulation pump 13, a mixing solenoid valve 23, a water supply solenoid valve 25, a circulation solenoid valve 18, and an electric heating element 42.

[0030] The data acquisition components are specifically hot water flow sensor 14, constant temperature outlet water temperature sensor 17, hot water tank temperature sensor 4, mixing tank temperature sensor 12, water level sensor 3, pipe antifreeze temperature sensor 43, and cold water flow sensor 44.

[0031] All the aforementioned actuators and data acquisition elements are electrically connected to the intelligent controller 1. The intelligent controller 1 controls the actuators based on the signals from each data acquisition element to achieve constant temperature water output, circulating heating, auxiliary heating, pipe antifreeze, and automatic water supply functions.

[0032] The cold water outlet 27 of the cold water storage tank 28 is connected to the front of the water booster pump 26, and two parallel pipelines are connected after the pump. One pipeline passes through the mixing solenoid valve 23 and the cold water inlet 22, and then connects to the cold water nozzle 19, which is used to inject cold water into the mixing tank 20. The other pipeline passes through the water inlet solenoid valve 25 and then connects to the water inlet 7 of the hot water collection tank 5. This pipeline is the water supply pipeline 8.

[0033] A branch line is provided on the water supply pipeline 8 and connected to the circulating heating outlet 41 of the mixing water tank 20 via the circulating solenoid valve 18.

[0034] The hot water outlet 6 of the hot water collection tank 5 is connected to the hot water inlet 15 of the mixing tank 20 via the hot water pipeline 9, the hot water booster pump 13, and the one-way valve 16. A manual switch valve is provided at the hot water outlet 6 for use during maintenance; it is normally open during normal operation of the equipment.

[0035] The thermostatic water outlet 10 of the mixing tank 20 is connected to the hot water tap 31 and the shower head 32 via a thermostatic water outlet pipe 11 and a thermostatic water supply pipe 24. A manual shower valve 30 is installed in front of the shower head 32. It should be noted that the thermostatic water outlet pipe 11 and the thermostatic water supply pipe 24 are actually the same pipe, only different in name due to their different installation locations. The thermostatic water outlet pipe 11 is closer to the mixing tank 20, while the thermostatic water supply pipe 24 is closer to the water outlet.

[0036] The mixing tank 20 is also equipped with an electric heating tube 42 for auxiliary heating when there is insufficient light. When there is electricity, the intelligent controller 1 will automatically turn on (optional function).

[0037] All the above-mentioned pipelines use 1216 integrated insulation pipes, and the joints are sealed with threads and wrapped with PTFE tape to prevent water leakage.

[0038] The hot water flow sensor 14 and the constant temperature outlet water temperature sensor 17 are installed on the constant temperature water pipe 24. The hot water flow sensor 14 is used to monitor whether the user is using water, while the constant temperature outlet water temperature sensor monitors the outlet water temperature.

[0039] The temperature sensor 4 and water level sensor 3 of the hot water collection tank are installed on the hot water collection tank 5 to monitor the temperature and water level of the hot water in the hot water collection tank 5. In this embodiment, the temperature sensor 4 and water level sensor 2 of the hot water collection tank are integrated into an integrated sensor 2. The integrated installation of the two sensors can reduce the number of openings in the hot water collection tank 5 and reduce heat loss.

[0040] The mixing tank temperature sensor 12 is installed on the upper part of the mixing tank 20 to monitor the internal water temperature.

[0041] The pipe antifreeze temperature sensor 43 is installed on the water supply pipe 8 to monitor whether the pipe is frozen.

[0042] The cold water flow sensor 44 is installed after the water booster pump 26. The presence or absence of a signal from the cold water flow sensor 44 is used to determine whether the cold water storage tank 28 is short of water.

[0043] All control lines for the aforementioned actuators and acquisition components use RVV2×0.5mm sheathed cable. When laying the cable, keep it away from high-temperature pipes to avoid signal interference.

[0044] The intelligent controller 1 is used to realize the functions of constant temperature water output, circulating heating, auxiliary heating, pipeline antifreeze and automatic water supply. The control logic of each function is described in detail below.

[0045] Constant temperature water output function: When the user turns on the hot water faucet 31 or shower valve 30, the hot water flow sensor 14 detects the flow signal, and the constant temperature water output temperature sensor 17 monitors the water temperature and transmits it to the intelligent controller 1. If the water temperature is higher than the preset value (adjustable from 39℃ to 43℃), the intelligent controller 1 cuts off the power to the hot water booster pump 13, starts the water supply booster pump 26, and opens the mixing solenoid valve 23, allowing cold water to spray from the cold water nozzle 19 into the mixing tank 20 to lower the water temperature. If the detected water temperature is lower than the preset value, the intelligent controller 1 restarts the hot water booster pump 13 and closes the water supply booster pump 26 and the mixing solenoid valve 23 to replenish high-temperature hot water. Through repeated adjustments, the water temperature is kept stable within the ±1℃ error range. After the user turns off the water supply, the signal from the hot water flow sensor 14 disappears, and the intelligent controller 1 stops all actuators from operating.

[0046] Circulating heating function: In automatic system operation, the hot water flow sensor 14 shows no flow signal. When the temperature of the hot water collection tank temperature sensor 4 is ≥42℃ and the temperature of the mixing tank temperature sensor 12 is <37℃, the intelligent controller 1 starts the hot water booster circulation pump 13 and opens the circulation solenoid valve 18. At this time, the water supply pipe 8 and the hot water pipe 9 form a circulation loop between the hot water collection tank 5 and the mixing tank 20, raising the water temperature in the mixing tank 20. When the temperature of the mixing tank temperature sensor 12 is 39℃, the intelligent controller 1 stops the circulation. When the temperature of the hot water collection tank temperature sensor 4 is <42℃, the system automatically circulates for 2 minutes every 40 minutes to ensure that the water in the mixing tank 20 is maintained at a suitable temperature, reducing the energy consumption of subsequent constant temperature regulation.

[0047] It should be noted that the circulating heating function is only activated when the user is not using hot water. That is, the smart controller 1 first checks whether the hot water flow sensor 14 has a signal. If there is no signal, it proceeds to the next logical judgment. If there is a signal, it means that the user is using hot water, and the circulating heating function will not be activated at this time.

[0048] Auxiliary heating function: Auxiliary heating is provided during continuous cloudy days and when there is insufficient sunlight. When the temperature of the mixing water tank temperature sensor 12 is <37℃ and the temperature of the hot water collecting tank temperature sensor 4 is <42℃, the intelligent controller 1 activates the electric heating element 42. Heating stops when the temperature of the mixing water tank temperature sensor 12 is ≥40℃.

[0049] Pipeline antifreeze function: When the temperature of the pipeline antifreeze temperature sensor 43 on the water supply pipeline 8 is <4℃, the intelligent controller 1 starts the above-mentioned circulating heating function and starts the auxiliary heating function as needed to prevent the pipeline from freezing in winter through circulating water. When the temperature of the pipeline antifreeze temperature sensor 43 is ≥12℃, the circulation stops.

[0050] Automatic water filling function: When the water level sensor 3 detects that the water level in the hot water tank 5 is lower than the "water shortage" threshold, the intelligent controller 1 outputs a command to start the water filling booster pump 26 and open the water filling solenoid valve 25, and cold water is injected into the hot water tank 5 through the water filling pipe 8. When the water level reaches the "full water" threshold (or the preset 50% water level threshold), the intelligent controller 1 cuts off the power to the water filling booster pump 26 and the water filling solenoid valve 25, and stops water filling.

[0051] During the automatic water filling process, the intelligent controller 1 monitors the cold water flow sensor 44 for a signal in real time. If a signal is present, the program runs normally; if no signal is present, it indicates that the cold water storage tank 28 is low on water. At this time, the intelligent controller 1 immediately shuts down the water supply booster pump 26 and the water supply solenoid valve 25, and activates a buzzer alarm every 20 minutes to remind the user to add water to the cold water storage tank 28.

[0052] In addition, the intelligent controller 1 can also realize the "temperature-controlled water supply" function: when the temperature sensor 4 of the hot water tank detects that the water temperature is ≥50℃, the intelligent controller 1 starts water supply to avoid the water temperature being too high and causing scale to form in the water; when the water temperature is ≤45℃, water supply stops to ensure the hot water storage in the hot water tank 5.

[0053] The power supply unit includes a solar panel 35, a solar panel controller 37, and a battery 38.

[0054] The solar panel 35 is installed on the front of the hot water tank 5 to convert solar energy into electrical energy. The solar panel 35 is electrically connected to the solar panel controller 37 through the output line 36. The solar panel controller 37 is then electrically connected to the intelligent controller 1 and the battery 38 to realize the distribution and storage of electrical energy.

[0055] During the day, the electricity generated by the solar panel 35 is processed by the solar panel controller 37. Part of the electricity is directly supplied to the intelligent controller 1, and the other part is stored in the battery 38. At night or when there is insufficient sunlight, the battery 38 supplies power to the intelligent controller 1 to ensure the system operates around the clock.

[0056] The adjustable installation unit includes a support frame, wheels 39 and a cement turntable 40. The hot water tank 5 and the heat collection pipe 29 are integrated and installed on the support frame. The bottom of the support frame is provided with four wheels 39 and placed in the cement turntable 40 which is slightly higher than the ground 33.

[0057] Before installation, a precast cement turntable 40 should be made 10cm above the ground, with a levelness error of ≤2cm. During installation, the distance between the cold water storage tank 28 and the hot water collection tank 5 should be ≤5m to reduce pipe losses.

[0058] When in use, the user can push the support frame and use the wheels 39 to rotate within the cement turntable 40 to adjust the orientation of the hot water tank 5 and the solar power panel 35, ensuring that the heat collection tube 29 and the solar power panel 35 are always in the best position for sunlight, thereby improving the efficiency of solar energy utilization.

[0059] Traditional solar water heaters typically require rooftop installation and rely on high water pressure for replenishment. However, in remote rural areas, and in specific scenarios such as vegetable greenhouses, vineyards, farms, fishponds, contracted farmland, temporary construction sites, and inland waterway transport vessels, suitable installation conditions or stable water pressure are often lacking, hindering the widespread application of solar water heaters. This invention effectively addresses the pain points of existing technologies, meets the diverse hot water needs of rural areas, and further promotes the in-depth application of solar water heaters in rural energy structures, thus possessing significant practical importance.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
