[0033] In order to make the utility model purposes, technical scheme and advantages more clearly, following combining embodiment, this utility model is further detailedly explained.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0034] As Figure 1 The utility model embodiment provides a kind of direct current frequency conversion pressurization backwater solar water heater, comprising:

[0035] Solar energy heat collector 1, water storage tank 2, backwater pipeline system 3, direct current frequency conversion pressurization pump 4, water pipe 5, lithium battery cabin 6, electric heating reserved mouth 7.

[0036] As Figure 2 Solar energy heat collector 1 is fixed on the surface of water storage tank 2 by screw;Backwater pipeline system 3 is fixed on the bottom of water storage tank 2 by screw;Direct current frequency conversion pressurization pump 4 is fixed on the upper right end of water storage tank 2 by screw;Water pipe 5 is connected to the right end of direct current frequency conversion pressurization pump 4.

[0037] The bottom of direct current frequency conversion pressurization pump 4 provided in the utility model embodiment is fixed with lithium battery cabin 6 by screw.

[0038] The right lower end of water storage tank 2 provided in the utility model embodiment is provided with electric heating reserved mouth 7.

[0039] Solar energy heat collector 1 is fixed on the surface of water storage tank 2 by screw;Backwater pipeline system 3 is fixed on the bottom of water storage tank 2 by screw;Direct current frequency conversion pressurization pump 4 is fixed on the upper right end of water storage tank 2 by screw;Water pipe 5 is connected to the right end of direct current frequency conversion pressurization pump 4.

[0040] The bottom of the water storage tank 2 is fixed with a backwater pipeline system 3 connected with hot water in the water storage tank to form a closed water circulation path. The direct-current variable frequency booster pump 4 is installed on the right end of the water storage tank above, connected with the water storage tank and the backwater system through a pipeline, and uses variable frequency technology to control the pressure and flow of water circulation. The booster pump ensures smooth water circulation and improves hot water flow efficiency, so that hot water quickly reaches the user end in the water pipe, especially suitable for high floor or long distance water supply scene.

[0041] The bottom of the direct-current variable frequency booster pump 4 is fixed with a lithium battery cabin 6, which provides independent direct-current power supply for the booster pump. The lithium battery is charged by the waste heat electric energy generated by the solar heat collector, realizing the self-provided power supply mode. In the case of power failure or unavailability of mains, the lithium battery can still guarantee the operation of the booster pump, thereby maintaining the stability and continuity of hot water circulation, adapting to the design requirements of energy saving and environmental protection.

[0042] The right lower end of the water storage tank 2 is reserved with an electric heating port 7. When the solar heating is insufficient or the water consumption is high, the electric heating device can quickly heat the water in the water storage tank through the reserved port, ensuring the continuity and stability of hot water supply. The electric heating function is manually or automatically started according to the actual demand of the user, and cooperates with the intelligent control module to optimize energy consumption and improve equipment operation efficiency by dynamically adjusting the proportion of solar energy and electric heating.

[0043] Through the above working principle, the direct-current variable frequency booster backwater solar water heater realizes efficient solar heat utilization, backwater circulation booster water supply, lithium battery self-power supply guarantee and electric heating auxiliary function, provides energy-saving, environmentally-friendly and efficient hot water solution for users, and is suitable for various water supply scenes.

[0044] The direct-current variable frequency booster backwater solar water heater mainly includes the following modules:

[0045] Solar heat collector 1: absorbs solar radiation and converts it into heat energy for heating water.

[0046] Water storage tank 2: stores hot water, and the built-in temperature control sensor monitors the water temperature in real time.

[0047] Direct-current variable frequency booster pump 4: used for backwater and pressure boosting, using direct-current variable frequency technology to realize high energy consumption ratio and stable water pressure output.

[0048] Backwater pipeline system 3: connecting the water heater, booster pump and water end, keeping the water temperature in the hot water pipeline constant through the automatic circulation control system.

[0049] Control system:

[0050] Water temperature detection module: real-time detection of water temperature in backwater pipe and water storage tank.

[0051] Water pressure detection module: detects the water pressure at the water outlet, adjusts the output power of the booster pump.

[0052] Intelligent controller: dynamically adjusts the working frequency of the booster pump according to water demand and temperature changes, achieving efficient boosting and energy-saving operation.

[0053] Power system:

[0054] DC power module: provides power to the system through photovoltaic components or batteries, reducing dependence on alternating current.

[0055] Backup AC power interface: switches to mains power supply when there is insufficient light or the battery is low.

[0056] When the user opens the hot water faucet, the system detects the water temperature in the pipeline through the temperature control sensor:

[0057] If the water temperature is lower than the set value, the DC variable frequency booster pump 4 starts, and the cold water is returned to the solar collector 1 for heating, and the water flow is circulated until the user's set suitable temperature is reached.

[0058] The booster pump dynamically adjusts the water pressure to ensure that the hot water quickly reaches the water outlet and the water pressure is constant.

[0059] When no one uses water, the system enters energy-saving mode, maintains water temperature monitoring, but stops water circulation, and only starts backwater circulation when the temperature difference is too large.

[0060] The solar collector 1 provides DC power to the system through photovoltaic components and batteries, and the photovoltaic components convert solar energy into electrical energy to power the DC variable frequency booster pump 4 and the control module. For insufficient light conditions, the system switches to mains power supply through the backup AC power interface to ensure continuous operation of the system. The entire power supply system links the power module, DC variable frequency booster pump 4 and control module through functional connection to provide efficient energy support.

[0061] The backwater pipeline system 3 of the water heater is composed of a water storage tank, a backwater pipeline and a DC variable frequency booster pump 4, forming a closed-loop water circulation system. When the user opens the hot water faucet, the system senses the water temperature and pressure in the pipeline through the positional relationship. If it is detected that the water temperature in the pipeline is lower than the set value, the control module immediately starts the booster pump to return the cold water in the pipe to the solar collector for heating, ensuring that the user end quickly obtains hot water.

[0062] The DC variable frequency booster pump 4 is installed between the water storage tank and the backwater pipe and connected to the pipeline system through the assembly relationship. The booster pump senses the pressure condition of the water outlet through the water pressure sensor and adjusts the working frequency in real time according to the change of water consumption, dynamically adjusts the water pressure output, and ensures stable hot water supply and uniform pressure. The DC variable frequency technology makes the pump run more energy-efficiently and adapt to different water use scenarios.

[0063] The temperature control module and the water flow sensor are respectively assembled at the key positions of the water storage tank and the return water pipeline, forming close functional linkage. The temperature control module monitors the water temperature of the water storage tank and the return water pipeline in real time, and determines whether to start the return water circulation through temperature difference comparison. The water flow sensor senses the water flow in the pipeline. When there is no water demand in the pipeline, the control system automatically enters the energy-saving mode, stops the return water circulation, and only starts the water flow circulation when the temperature difference is too large.

[0064] The pipeline connection relationship of the water heater ensures efficient and smooth transmission of water flow from the water storage tank to the water end. When the user opens the hot water faucet, the water heater detects that the user end water temperature is lower than the set value according to the positional relationship, and immediately starts the return water circulation to quickly deliver the hot water in the water storage tank to the user end, realizing "instant heating". The assembly relationship of the booster pump and the return water pipeline further improves the water flow speed and water supply stability.

[0065] The entire system is intelligently managed by the central controller, which is assembled at the control center position of the water storage tank and connected with the booster pump, the temperature control module, the water flow sensor and the power module. According to the comprehensive data of temperature, pressure and water demand, it dynamically adjusts the working state of each module to ensure stable hot water supply and minimum energy consumption. At the same time, the system can learn the user's water usage habits through sensor data, optimize operating parameters, and further improve user experience and energy saving effect.

[0066] Through the close linkage of function, position, connection and assembly relationship, the system forms an efficient and intelligent hot water supply mechanism, which significantly improves energy saving and environmental protection and user experience.

[0067] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make any modification, equivalent replacement and improvement within the technical range disclosed by the present application, as long as it is within the spirit and principles of the present application.
