DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1 and 5, a gas water heater intelligent temperature control and water saving device comprises a gas water heater 1 connected to a water inlet via a pipe 1 2, an output end of the gas water heater 1 is connected to a water outlet via a pipe 2 3, the water inlet is used to provide a water source for the gas water heater 1, the water source is heated by the gas water heater 1, and hot water is released through the water outlet, which can be specifically configured as a faucet or a shower, a water circulation component is connected between the pipe 1 2 and the pipe 2 3, and is used for the water flowing out of the pipe 2 3 to re-enter the pipe 1 2, and the water released from the gas water heater 1 that does not meet the temperature standard is recycled, so that the gas water heater 1 is heated again to reduce water waste.

The water circulation component includes a tee 1 4 installed on a pipe 1 2, and a tee 2 5 is installed on a pipe 2 3. A pipe 3 6 is connected between the tee 1 4 and the tee 2 5, and a water pump 7 is installed on the pipe 3 6. The water pump 7 drives the water flow and increases the water pressure. Firstly, a circulating water circuit with a higher pressure is formed, and secondly, the gas water heater 1 is driven to work and heat the water circulation in the pipeline.

A one-way valve 8 is installed between the water pump 7 and the three-way 5 through the pipeline 3 6 to limit the movement direction of the water flow.

The water circulation component also includes a temperature sensor 9 installed on the output end of the gas water heater 1. The temperature sensor 9 can adopt a sensor with model WDF22J-100-024, and the water pump 7 is electrically connected to a control mainboard 10.

The control main board 10 is connected to the control terminal 11, and the control terminal 11 includes a control panel 1101, a display screen 1102 and a buzzer 1103. It is worth noting that the controller mainly composed of the control main board 10 and the control terminal 11 can adopt a Siemens S7-1200 control device, and the control main board can also use Arduino as the main control board. The control terminal 11 includes a control panel 1101, a display screen 1102 and a buzzer 1103. By setting the control panel 1101, the display screen 1102 and the buzzer 1103 related to the control device, it is convenient to manually control the control device. The control main board 10 issues command information according to the collected information, which is more convenient for manual control and use. The buzzer 1103 is used to indicate the working status of the gas water heater 1, which is convenient for manual management and real-time control of the working progress of the gas water heater 1.

It should be noted that the specific models and specifications of the gas water heater 1, water pump 7, temperature sensor 9 and controller need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

Referring to FIG. 2 , by adding a pipe 4 to the circulating water circuit assembly, a hydroelectric generator located between the water inlet end and the three-way 1 4 is arranged by using the pipe 4, and the hydroelectric generator is electrically connected to a battery electrically connected to the control mainboard 10. It is worth noting that the electric energy generated by the hydroelectric generator enters the battery for storage to provide electric energy for driving the control mainboard 10 and the control end 11.

It is worth noting that the battery can also be connected to an external power source. When the electricity generated by the hydroelectric generator is insufficient, the battery can be supplemented with electricity through the external power source, so that the battery can be used for energy supply during normal use. The hydroelectric generator can use an axial flow propeller turbine with a runner model of 560 to further ensure that the water flow can drive it to run smoothly, and the battery can use a long-life lithium battery with a model of 6-QAW-54a to reduce power loss.

Based on the above solution, it can be further defined, specifically referring to Figures 4 and 5 of the specification:

A water purification end 12 is fixedly installed between the water inlet end and the three-way 4, one end of the water purification end 12 is provided with a water inlet 13 for connecting to the water inlet end, and the other end of the water purification end 12 is provided with a drain port 14 for connecting to the three-way 4, and the water purification end 12 is used to filter and purify the water entering the gas water heater 1 to reduce the formation of scale in the gas water heater 1;

A first water purification chamber 15 connected to the water inlet 13 is provided in the upper end of the water purification end 12, a second water purification chamber 16 connected to the drain port 14 is provided in the lower end of the water purification end 12, a purification micropore 17 is provided between the first water purification chamber 15 and the second water purification chamber 16, a waterproof motor 18 located at the base of the first water purification chamber 15 is provided at the water purification end 12 through the drain port 14, a water purification cover 19 located in the first water purification chamber 15 and threadedly connected to the output end of the waterproof motor 18 is provided at the water purification end 12 through the water inlet 13, and a debris removal hole 22 is provided in the water purification cover 19;

It is worth mentioning that a guide ring groove 20 is opened in the upper end of the first water purification chamber 15, and a sealing gasket 21 is integrally connected to the water purification cover 19 and rotatably sleeved in the guide ring groove 20. The sealing gasket 21 is tough and can be stretched and deformed according to the needs of disassembly and assembly of the water purification cover 19.

The water entering the water purification end 12 through the water inlet 13 directly enters the water purification cover 19. By controlling the operation of the waterproof motor 18, the output end of the waterproof motor 18 drives the water purification cover 19 to rotate at a high speed in the first water purification chamber 15. The relatively clean water enters the first water purification chamber 15 through the impurity removal hole 22. Because the water purification cover 19 rotates at a high speed, the water level at the center of the first water purification chamber 15 is relatively low, while the water level at the edge is relatively high. The clean water then enters the second water purification chamber 16 through the purification micropores 17, and enters the three-way 4 through the drain port 14;

The water source at room temperature entering the water purification end 12 is preliminarily purified by using the water purification cover 19, so that large-volume impurities in the water source are retained in the water purification cover 19, and then the relatively clean water source enters the first water purification chamber 15, and is further filtered through the purification micropores 17, so that the clean water source enters the second water purification chamber 16, and finally enters the three-way 4 through the drain port 14. The water source is dynamically filtered through the water purification end 12 to ensure the cleanliness of the water source entering the gas water heater 1.

The functional principle of the utility model can be explained through the following operation modes:

The water flow is driven by the water pump 7 and the water pressure is increased. Firstly, a circulating water circuit with a relatively high pressure is formed. Secondly, the gas water heater 1 is driven to work and heat the water circulation in the pipeline until the water discharged from the gas water heater 1 reaches the set temperature. Then, the one-way water circulation system stops working, thereby achieving the purpose of saving water resources, gas resources and precise temperature control.

In addition, in order to save power, pipe four is installed on the water supply pipeline, and a hydroelectric generator is set up using pipe four. The movement of water flow drives the hydroelectric generator to operate, and the electric energy produced by the hydroelectric generator is stored in the battery. The battery powers the control main board 10, the control panel 1101, the display screen 1102 and the buzzer 1103.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
