[0002] Gas water heaters, also known as gas water heaters, are gas appliances that use gas as fuel and transfer heat to cold water flowing through a heat exchanger through combustion heating to prepare hot water. Gas water heaters are mainly composed of valve body assemblies, main burners, low-fire burners, heat exchangers, safety devices, etc. They also include flues for flue-type water heaters and forced exhaust devices for forced exhaust water heaters. The valve body assembly controls the working procedures of the entire water heater.

This heat is not utilized, resulting in a certain amount of heat energy waste. In addition, if the temperature of the exhaust pipe is not treated under certain conditions, it will cause emergency fire hazards and needs to be improved. In view of this, we propose a new type of gas water heater exhaust pipe heat energy recycling device. Utility Model Content

[0023] A novel heat energy recycling device for a gas water heater exhaust pipe comprises a water heater 100. A smoke exhaust pipe 200 and a water inlet pipe 300 are arranged on the top of the water heater 100. A heat exchange water inlet pipe 500 and a water outlet pipe 400 are arranged at the bottom of the water heater 100. A water storage box 800 is arranged at the bottom of the smoke exhaust pipe 200. A spiral transducer 700 is arranged inside the smoke exhaust pipe 200.

[0024] First, in order to ensure that the spiral transducer 700 can be installed in the smoke exhaust pipe 200 and the smoke exhaust pipe 200 can prevent the condensed water from flowing back, specifically, the smoke exhaust pipe 200 is Z-shaped, a heat exchange chamber 600 is arranged inside the smoke exhaust pipe 200, and a spiral transducer 700 is arranged in the center of the heat exchange chamber 600.

[0025] Next, in order to ensure that the spiral transducer 700 can absorb heat to the maximum extent, and the water inlet pipe 300 can discharge water into the spiral transducer 700 and then discharge it through the water inlet pipe 500 after heat exchange, specifically, the spiral transducer 700 is shaped like a multi-turn thread that is close to the wall of the heat exchange chamber 600, the upper end of the spiral transducer 700 is connected to the water inlet pipe 300, and the lower end of the spiral transducer 700 is connected to the water inlet pipe 500 after heat exchange.

[0026] Secondly, in order to ensure that the water storage box 800 can store water and be connected to the heat exchange chamber 600, and the water storage box 800 can discharge water, specifically, the center of the water storage box 800 is a cavity structure, the cavity of the water storage box 800 is connected to the heat exchange chamber 600, and a water outlet valve 900 is provided at the bottom of the water storage box 800.

[0027] Finally, in order to ensure that the water inlet pipe 500, the water outlet pipe 400 and the smoke exhaust pipe 200 can maintain the internal temperature after heat exchange, and the spiral transducer 700 can absorb heat quickly, specifically, the outside of the water inlet pipe 500, the water outlet pipe 400 and the smoke exhaust pipe 200 are all provided with polymer insulation materials after heat exchange, and the spiral transducer 700 adopts materials with high thermal conductivity.

[0028] Working principle: When the device is needed to recover heat energy, first the water heater is operated, and a large amount of high-heat waste flows inside the exhaust pipe 200. Then the water inlet pipe 300 discharges the water flow into the spiral transducer 700. The spiral transducer 700 forms multiple turns of threads that are close to the wall of the heat exchange chamber 600 and uses its own high thermal conductivity material to introduce the heat and thermal radiation in the exhaust pipe 200 into the water flow to heat the water. Secondly, after the heat exchange, the water inlet pipe 500 discharges the heated water into the water heater to complete the heat energy recovery. In some cases, condensed water is easily generated on the outer wall of the spiral transducer 700 during the heat exchange process inside the heat exchange chamber 600. By designing the exhaust pipe 200 into a Z shape, the condensed water is collected into the water storage box 800 at an oblique angle, and the condensed water can be discharged through the outlet valve 900.
