Description

Technical Field

[0001] This utility model relates to the field of gas water heater technology, and more specifically to an energy-saving gas water heater. Background Technology

[0002] Existing gas water heaters have significant deficiencies in their anti-freezing function and energy utilization in low-temperature environments. Traditionally, gas water heaters rely on external power to maintain their anti-freezing function, such as using electric heating to prevent pipes from freezing and cracking. However, users often forget to turn on the power or experience unexpected power outages, causing the appliance to shut down and rendering the electric heating anti-freezing function completely ineffective. In low-temperature environments, the internal pipes of the water heater lack effective heating protection, leading to a sharp increase in the risk of freezing and cracking. This can result in minor damage to the equipment and increased repair costs, or even serious safety hazards such as leaks, threatening the safety of users' property. While some models incorporate electric heating anti-freezing structures, the problems of user dependence on power and failure during power outages remain widespread.

[0003] When a gas water heater is running, the exhaust gases produced by combustion are discharged through the ventilation system. The kinetic energy carried by these gases is not effectively utilized, resulting in energy waste. Furthermore, when the external power supply is interrupted, the water heater stops operating entirely, failing to provide heating. Its built-in anti-freeze monitoring device also malfunctions due to the power outage, further exacerbating the equipment risk in low-temperature environments. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide an energy-saving gas water heater, which aims to solve the technical problem of the failure of the antifreeze function of traditional gas water heaters due to power outages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An energy-saving gas water heater includes a water heater body, characterized in that it further includes an exhaust mechanism, a wind power generation component, and an anti-freeze alarm component. The exhaust mechanism is located at the exhaust port on the top of the water heater body, the anti-freeze alarm component is located on the water heater body, and the wind power generation component is located inside the exhaust mechanism and electrically connected to the anti-freeze alarm component.

[0007] In one embodiment, the exhaust mechanism includes a smoke hood, an exhaust fan, and an exhaust pipe. The exhaust port of the water heater body, the smoke hood, the exhaust fan, and the exhaust pipe are connected in sequence, and the wind power generation component is disposed inside the exhaust pipe.

[0008] In one embodiment, the wind power generation component is disposed at one end of the exhaust pipe near the exhaust fan.

[0009] In one embodiment, the wind power generation component includes power generation blades and a wind turbine, the power generation blades are connected to the wind turbine, and the wind turbine is electrically connected to the anti-freeze alarm component via a connecting wire.

[0010] In one embodiment, the power generation blade is disposed on the exhaust path of the exhaust pipe, and the drive shaft of the power generation blade is aligned with the axial direction of the exhaust pipe.

[0011] In one embodiment, the drive shaft axis of the exhaust fan is perpendicular to the drive shaft axis of the power generation blades.

[0012] In one embodiment, the anti-freeze alarm component includes a battery and an operation panel. The battery is located inside the water heater body, and the operation panel is located on the water heater body. The operation panel is electrically connected to the battery, and the wind power generation component is electrically connected to the battery via a connecting wire.

[0013] In one embodiment, the operation panel is provided with a display screen, and the operation panel is provided with a temperature sensor, a controller and a buzzer. The temperature sensor is used to detect the ambient temperature of the water heater body. The output terminal of the temperature sensor is connected to the input terminal of the controller, and the output terminal of the controller is connected to the display screen and the buzzer respectively.

[0014] In one embodiment, the operation panel is also electrically connected to an external power source, and the battery is electrically connected to the external power source via a bidirectional switching switch; the controller is also provided with a power detection module, the input terminal of which is electrically connected to the power detection terminal of the battery, and the output terminal of which is electrically connected to the control terminal of the bidirectional switching switch.

[0015] In one embodiment, the water heater body includes an outer shell, a combustion chamber and a burner arranged sequentially from top to bottom within the outer shell, the exhaust port of the combustion chamber being connected to the exhaust mechanism, and the anti-freeze alarm component being connected to the outer shell.

[0016] The beneficial effects of this utility model compared with the prior art are as follows: By installing a wind power generation component within the exhaust mechanism and electrically connecting it to the anti-freeze alarm component located in the main body of the water heater, the kinetic energy of the exhaust gas during the flue gas exhaust process drives the wind power generation component to generate electricity, providing power to the anti-freeze alarm component. This achieves the recovery and utilization of exhaust gas energy, reduces dependence on external power sources, and achieves energy-saving and environmentally friendly effects. The electrical connection design between the wind power generation component and the anti-freeze alarm component ensures that the anti-freeze alarm component receives power support whether the external power supply is normal or interrupted, ensuring its continuous monitoring and response capabilities at all times. The interconnected structure of the exhaust mechanism ensures smooth exhaust gas discharge while providing a stable kinetic energy source for the wind power generation component, enabling the power generation process and the water heater's exhaust function to operate in synergy. Through the structural synergy between the wind power generation component, the exhaust mechanism, and the anti-freeze alarm component, the waste of exhaust gas kinetic energy is avoided, and the continuous power supply capability of the anti-freeze alarm component provides a structural foundation for the functional reliability of the water heater under different power supply conditions.

[0029] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0030] See Figures 1 to 5 As shown in the figure, this utility model embodiment discloses an energy-saving gas water heater, including a water heater body 1, an exhaust mechanism 2, a wind power generation component 3, and an anti-freeze alarm component 4. The exhaust mechanism 2 is located at the exhaust port on the top of the water heater body 1, the anti-freeze alarm component 4 is located on the water heater body 1, and the wind power generation component 3 is located inside the exhaust mechanism 2 and electrically connected to the anti-freeze alarm component 4.

[0031] Specifically, in this embodiment, the energy-saving gas water heater uses the main body 1 of the water heater as the basic frame, and integrates the exhaust mechanism 2 at its exhaust port; the wind power generation component 3 is embedded inside the flue pipe 23, and uses the kinetic energy of the exhaust gas generated by the combustion of gas during the exhaust process to convert the kinetic energy into electrical energy through the wind power generation component 3; it is electrically connected to the antifreeze alarm component 4 located on the surface of the main body 1 of the water heater through the connecting wire 5, providing the antifreeze alarm component 4 with an energy source independent of the external power source, so that it always keeps the machine on and monitors the temperature in real time, thus forming a complete alarm system of "kinetic energy acquisition-electrical energy transmission-early warning response", thereby solving the problems of power failure of the antifreeze function and waste of exhaust gas kinetic energy caused by the reliance on mains power in traditional water heaters.

[0032] The energy-saving gas water heater in this embodiment achieves efficient recovery and utilization of waste gas kinetic energy, reducing the overall energy consumption of the equipment; by constructing a power supply link independent of the mains power, it ensures that the anti-freeze alarm component 4 continues to operate under any power supply condition, improving the reliability of pipeline protection in low-temperature environments.

[0033] In one embodiment, the exhaust mechanism 2 includes a smoke hood 21, an exhaust fan 22, and an exhaust pipe 23. The exhaust port of the water heater body 1, the smoke hood 21, the exhaust fan 22, and the exhaust pipe 23 are connected in sequence, and the wind power generation component 3 is disposed in the exhaust pipe 23.

[0034] Specifically, the exhaust mechanism 2 consists of a smoke hood 21, an exhaust fan 22, and an exhaust pipe 23 connected in sequence to form a complete exhaust gas discharge path. When the water heater body 1 is running, the water heater body 1 ignites the gas to generate high-temperature exhaust gas, which enters the smoke hood 21 through the exhaust port for collection, and is then pressurized by the exhaust fan 22 and pushed to the exhaust pipe 23 for discharge. The wind power generation component 3 in the exhaust pipe 23 is driven by the high-speed airflow passing through the exhaust pipe 23 to generate electricity, and the electrical energy is transmitted to the anti-freeze alarm component 4 through the line, so that it can perform temperature monitoring and early warning functions when the external power supply is normal or disconnected.

[0035] In one embodiment, the wind power generation component 3 is disposed at one end of the exhaust pipe 23 near the exhaust fan 22.

[0036] Specifically, the wind power generation component 3 is fixedly installed at the end of the exhaust pipe 23 near the exhaust fan 22, at the junction of the exhaust fan 22 outlet and the main body of the exhaust pipe 23, ensuring that it directly receives the high-speed airflow accelerated by the exhaust fan 22. It is understandable that the pressurization effect of the exhaust fan 22 on the exhaust gas can significantly increase the airflow velocity within the exhaust pipe 23. Placing the wind power generation component 3 at the end of the exhaust pipe 23 near the exhaust fan 22 maximizes the utilization of airflow energy. Simultaneously, the distance between the exhaust fan 22 and the smoke hood 21 buffers the high temperature, reducing the impact of exhaust gas temperature on the wind power generation component 3.

[0037] Understandably, the exhaust fan 22 includes an air guide shroud, an impeller, and a rotating motor. The impeller is located inside the air guide shroud, and the rotating motor drives the impeller to rotate, thereby moving the airflow. The air inlet of the air guide shroud is connected to the air outlet of the smoke collection hood 21, and the air outlet of the air guide shroud is connected to the air inlet of the exhaust pipe 23. During operation, the exhaust fan 22 generates negative pressure through the rotation of the impeller, which accelerates the exhaust gas in the smoke collection hood 21 and pushes it into the exhaust pipe 23. The wind power generation component 3 located at the outlet of the exhaust fan 22 is impacted by the high-speed airflow, increasing the blade rotation speed and significantly improving the power generation efficiency.

[0038] In this embodiment, without changing the overall size of the exhaust mechanism 2, the energy conversion efficiency is improved by optimizing the position, thereby increasing the power generation while avoiding the high-temperature area of ​​the water heater body 1 and extending the service life of the wind power generation components.

[0039] Understandably, during the operation of a gas water heater, the exhaust fan 22, as a core component of the exhaust mechanism 2, plays a crucial role in rapidly discharging the exhaust gases produced during combustion. To ensure the safe and stable operation of the exhaust fan 22 and prevent equipment damage or safety hazards due to abnormal conditions, a wind speed protection device is installed inside the exhaust fan 22. The main function of the wind speed protection device is to monitor the operating status of the exhaust fan 22 in real time. When excessive exhaust resistance is detected, a shutdown alarm mechanism is quickly triggered to prevent damage to the exhaust fan 22 and other related components due to overload.

[0040] Furthermore, the wind speed protection device monitors the operating parameters of the exhaust fan 22 in real time using built-in sensors (such as pressure sensors or speed sensors). The pressure sensor monitors the air pressure difference between the inlet and outlet of the exhaust fan 22. When the exhaust duct is blocked, the smoke exhaust pipe is excessively bent, or there is backflow from external wind, causing a significant increase in exhaust resistance, the air pressure difference will exceed the normal operating range. The speed sensor monitors the change in the speed of the impeller of the exhaust fan 22 to determine the resistance. When the resistance is too high, the impeller speed will decrease significantly. The sensors transmit the real-time monitored data to the controller. The controller has preset normal operating parameter ranges. When the received monitoring data exceeds this range, it is determined to be an abnormal situation, and a command is issued to trigger a shutdown alarm.

[0041] In one embodiment, the wind power generation component 3 includes a power generation blade 31 and a wind turbine 32. The power generation blade 31 is connected to the wind turbine 32, and the wind turbine 32 is electrically connected to the anti-freeze alarm component 4 via a connecting wire 5.

[0042] Specifically, the wind power generation assembly 3 consists of a power generation blade 31 and a wind turbine 32. The power generation blade 31 is fixedly connected to the input shaft of the wind turbine 32 via a drive shaft. The wind turbine 32 converts the kinetic energy generated by wind power into electrical energy. Further, the wind power generation assembly 3 also includes a fan shroud 33 and a fixing bracket 34. The power generation blade 31 is connected to the fan shroud 33 via the fixing bracket 34. The fan shroud 33 is connected to the exhaust fan 22. The outer diameter of the fan shroud 33 is slightly smaller than the inner diameter of the exhaust pipe 23. The end of the exhaust pipe 23 near the exhaust fan 22 is fitted over the fan shroud 33, allowing the exhaust gas pushed out by the exhaust fan 22 to flow through the fan shroud 33 to the exhaust pipe 23 and then be discharged.

[0043] Understandably, the core structure of the wind turbine 32 includes a stator and a rotor. The rotor, as a rotating component, has permanent magnets embedded in its outer circumference (or electromagnetic coils installed internally), and is linked to the generating blades 31 via a drive shaft. When the generating blades 31 drive the rotor to rotate, the permanent magnets (or electromagnetic coils) rotate synchronously with the rotor, forming a rotating magnetic field. The stator is fixed inside the casing of the wind turbine 32, and stator windings (conductive coils) are wound around its inner side. The stator windings remain stationary, creating relative motion with the rotating magnetic field of the rotor. According to the law of electromagnetic induction, when the permanent magnets (or electromagnetic coils) of the rotor rotate, the magnetic field they generate undergoes relative motion with the stator windings, cutting magnetic field lines. This causes a change in the magnetic flux within the stator windings, thereby inducing an electromotive force in the stator windings and generating electrical energy.

[0044] In this embodiment, when the gas water heater is running, the exhaust gas generated by combustion is accelerated by the smoke hood 21 and the exhaust fan 22 to form a high-speed airflow, which is then discharged through the exhaust pipe 23. The power generation blades 31 installed in the exhaust pipe 23 are driven to rotate by the airflow, converting the kinetic energy of the flue gas into the mechanical energy of the power generation blades 31. The power generation blades 31 are rigidly connected to the rotor of the wind turbine generator 32 through a drive shaft, driving the rotor to rotate synchronously, thereby generating electrical energy.

[0045] In one embodiment, the power generation blade 31 is disposed on the exhaust path of the exhaust pipe 23, and the drive shaft of the power generation blade 31 is aligned with the axial direction of the exhaust pipe 23.

[0046] Specifically, the power generation blade 31 is propeller-shaped and arranged axially along the exhaust path of the exhaust pipe 23. Its drive shaft coincides with the axis of the exhaust pipe 23. At the same time, a gap is reserved between the outer edge of the power generation blade 31 and the inner wall of the exhaust pipe 23 to avoid friction between the power generation blade 31 and the inner wall of the exhaust pipe 23.

[0047] Understandably, the axial layout allows the exhaust gas to flow smoothly along the axis of the exhaust pipe 23 over the power generation blades 31. Through the tilt design of the power generation blades 31, aerodynamic principles are used to generate continuous driving force, while reducing energy loss caused by airflow turbulence.

[0048] During operation, when the exhaust gas passes through the exhaust pipe 23 axially, the generator blade 31 is impacted by the airflow and rotates around the drive shaft. Its torque is transmitted to the wind turbine 32, which optimizes the hydrodynamic performance, reduces the exhaust resistance, and improves the efficiency of the generator blade 31 in capturing air kinetic energy, ensuring that the normal exhaust of the water heater body 1 is not affected.

[0049] In one embodiment, the drive shaft axis of the exhaust fan 22 is perpendicular to the drive shaft axis of the power generation blade 31.

[0050] Specifically, the drive shaft of the exhaust fan 22 is horizontally arranged, and its axis intersects perpendicularly with the axis of the exhaust pipe 23; the drive shaft of the power generation blade 31 is vertically arranged, coinciding with the axis of the exhaust pipe 23, forming an orthogonal axis system structure. The two are spatially isolated by a partition inside the exhaust pipe 23. The exhaust fan 22 generates suction perpendicular to the axis of the exhaust pipe 23 by rotating on its horizontal axis, quickly drawing exhaust gas into the exhaust pipe 23; the power generation blade 31 captures axial airflow energy by rotating on its vertical axis. The motion trajectories of the two are orthogonal, avoiding mechanical interference and airflow disturbance.

[0051] During operation, the impeller of the exhaust fan 22 rotates horizontally, generating negative pressure and drawing exhaust gas from the smoke collection hood 21 into the exhaust pipe 23; the power generation blades 31 rotate vertically to generate electricity under the action of axial airflow. The speeds of the two do not interfere with each other, ensuring that the exhaust and power generation functions operate independently.

[0052] In one embodiment, the antifreeze alarm component 4 includes a storage battery 41 and an operation panel 42. The storage battery 41 is located inside the water heater body 1, and the operation panel 42 is located on the water heater body 1. The operation panel 42 is electrically connected to the storage battery 41, and the wind power generation component 3 is electrically connected to the storage battery 41 via a connecting wire 5.

[0053] Specifically, the anti-freeze alarm component 4 includes a built-in battery 41 and an exposed control panel 42 on the main body of the water heater 1. The battery 41 is fixed inside the main body of the water heater 1, and the control panel 42 is embedded in the front end of the main body of the water heater 1. The two are electrically connected by a connecting wire 5. The output end of the wind power generation component 3 is connected to the charging interface of the battery 41 through an independent line, thereby creating an independent power supply circuit of "wind power generation - energy storage of battery 41 - power consumption of control panel 42" while retaining the external power supply interface, ensuring that the alarm function is not interrupted under any power supply state.

[0054] Understandably, in this embodiment, the wind turbine 32 generates alternating current based on the principle of electromagnetic induction and converts it into direct current through a bridge rectifier circuit before storing it in the battery 41. The bridge rectifier can convert both the positive and negative half-cycles of the alternating current into current in the same direction, outputting pulsating direct current and improving energy utilization efficiency. Specifically, the generator blades 31 in the exhaust pipe 23 drive the rotor of the wind turbine 32 to rotate, and the stator windings cut magnetic field lines to generate alternating electromotive force, outputting alternating current. The alternating current output by the wind turbine 32 is converted into direct current through the bridge rectifier circuit. The rectified direct current is transmitted to the battery 41 through the connecting line 5, and the battery 41 converts electrical energy into chemical energy through a chemical reaction for storage.

[0055] In one embodiment, the operation panel 42 is provided with a display screen 421, and the operation panel 42 is provided with a temperature sensor 422, a controller and a buzzer. The temperature sensor 422 is used to detect the ambient temperature of the water heater body 1. The output terminal of the temperature sensor 422 is connected to the input terminal of the controller, and the output terminal of the controller is connected to the display screen 421 and the buzzer respectively.

[0056] Specifically, the control panel 42 has an LED display screen 421 on its surface, and integrates a temperature sensor 422, a controller, and a buzzer. The temperature sensor 422 is fixed to the back of the control panel 42, close to the outer shell of the water heater body 1; the buzzer is fixedly connected to the control panel 42. The temperature sensor 422 collects the ambient temperature data of the water heater body 1 in real time. The controller displays the real-time temperature data on the display screen 421 and triggers the buzzer alarm based on a preset threshold, realizing proactive early warning in low-temperature environments. The human-machine interface is simple and intuitive.

[0057] Furthermore, during operation, the temperature sensor 422 collects data once within a preset time period and transmits it to the controller for comparison with a preset threshold. When the collected temperature data is detected to be lower than the preset threshold, the controller controls the buzzer to emit a continuous alarm sound, and the display screen 421 simultaneously displays an "anti-freeze icon" until the user takes measures or the temperature rises.

[0058] It is understood that the anti-freeze alarm component 4 in this embodiment only implements a buzzer reminder function, and the alarm temperature should be slightly higher than 0 degrees Celsius, the temperature at which water freezes. Therefore, this embodiment preferably sets the preset threshold to 8 degrees Celsius. Water heaters are generally installed in the kitchen. When the temperature of the water heater body 1 located indoors is 8 degrees Celsius, the temperature of the outdoor water pipes and the water pipes inside the building walls is generally lower. Setting the preset threshold to 8 degrees Celsius can effectively prevent the situation where the temperature of the water heater body 1 is higher than 0 degrees Celsius while the outdoor water pipes are at 0 degrees Celsius and freeze.

[0059] In one embodiment, the operation panel 42 is also electrically connected to an external power source, and the battery 41 is electrically connected to the external power source via a bidirectional switching switch; the controller is also provided with a power detection module, the input terminal of which is electrically connected to the power detection terminal of the battery 41, and the output terminal of which is electrically connected to the control terminal of the bidirectional switching switch.

[0060] Specifically, the control panel 42 is also electrically connected to an external power source. In addition to being connected to the battery 41 via the connecting cable 5, the control panel 42 also has an independent external power interface, allowing it to directly access an external power source (such as AC mains power) to obtain electrical energy. This ensures that the control panel 42 can still operate normally when the battery 41 has insufficient power or when wind power generation is interrupted. This design forms a dual power supply system, improving the stability and reliability of the power supply to the control panel 42.

[0061] Furthermore, a bidirectional switch is incorporated into the circuit to enable automatic switching between the external power supply and the battery 41. The bidirectional switch employs an electromagnetic relay, connected in series between the external power supply and the battery 41. The control terminal of the bidirectional switch is connected to the controller within the operation panel 42. The input terminal of the bidirectional switch is connected to the external power supply, and its output terminal is connected to the power supply interface of the operation panel 42. Simultaneously, the battery 41 is connected in parallel to the output terminal of the bidirectional switch. The controller controls the on / off state of the bidirectional switch by detecting the voltage of the battery 41, thereby achieving automatic switching between the external power supply and the battery 41.

[0062] During operation, if the controller detects an external power supply, when the voltage of the battery 41 is greater than a preset threshold, the bidirectional switching switch is opened, and the operation panel 42 is powered by the battery 41; when the voltage of the battery 41 is less than the preset threshold, the bidirectional switching switch is closed, and the external power supply powers the operation panel 42 and the battery 41. The switching process is uninterrupted.

[0063] Furthermore, the power detection module is integrated into the controller. It monitors the charging and discharging current of the battery 41 through a sampling resistor and calculates the remaining power percentage by combining the voltage data. The power detection module communicates with the controller to update the power data in real time. The controller sends commands to the bidirectional switching switch according to preset thresholds to achieve automated management of charging, discharging, and sleep states, avoiding overcharging or over-discharging.

[0064] During operation, the sampling resistor detects the current signal in real time, converts it to digital and inputs it to the controller. The controller calculates the cumulative charge and discharge amount through integration. When the battery level reaches a threshold, it immediately controls the bidirectional switching switch to operate. For example, if the upper limit of the preset threshold for battery 41 is set to 60% and the lower limit is set to 40%, when the controller detects the connection of an external power source, if the battery level of battery 41 drops to 40%, battery 41 stops supplying power to the operation panel 42 and automatically starts charging the external power source until the battery level of battery 41 rises back to 60%. If the battery level of battery 41 rises to 60%, it switches to supplying power to the operation panel 42 until the battery level of battery 41 drops back to 40%. This reduces power consumption during user operation while ensuring that battery 41 always retains a portion of its power to power the operation panel 42 in case of unexpected power outages.

[0065] In one embodiment, the water heater body 1 includes an outer shell 11, a combustion chamber 12 and a burner 13 arranged sequentially from top to bottom inside the outer shell 11, the exhaust port of the combustion chamber 12 is connected to the exhaust mechanism 2, and the antifreeze alarm component 4 is connected to the outer shell 11.

[0066] Specifically, the water heater body 1 includes an outer shell 11, a combustion chamber 12, and a burner 13. The combustion chamber 12 is located on the upper part of the outer shell 11, and the burner 13 is installed below the combustion chamber 12. The two are connected by a gas pipeline. The exhaust port of the combustion chamber 12 is connected to the inlet flange of the smoke hood 21 of the exhaust mechanism 2. The smoke hood 21 and the exhaust fan 22 are integrated in the top space of the outer shell 11, and the exhaust pipe 23 extends out from the top of the outer shell 11. The operation panel 42 of the anti-freeze alarm component 4 is embedded in the front end of the outer shell 11 for easy user operation.

[0067] Understandably, the combustion chamber 12 is located above the interior of the water heater body 1, and has a cylindrical or rectangular cavity structure with an insulation layer on the inner wall to reduce heat loss. The top of the combustion chamber 12 has an exhaust vent that connects to the smoke hood 21, and the bottom connects to the burner 13, forming a closed combustion space. As the core area for the mixing and combustion of gas and air, the combustion chamber 12, through its rational spatial design, ensures complete combustion of the gas, producing high-temperature flue gas, and transferring heat to the heat exchanger to heat the cold water. The burner 13 is installed below the combustion chamber 12 and typically consists of a nozzle, a mixing chamber, and a burner. Gas enters the nozzle through the intake pipe, and when ejected at high speed, it creates negative pressure in the mixing chamber, drawing in air and mixing to form combustible gas. After being ignited by the ignition device, it burns stably within the combustion chamber 12. The resulting high-temperature flue gas releases heat through the heat exchanger and then enters the exhaust mechanism 2 through the exhaust vent.

[0068] In this embodiment, the gas is mixed with air and ignited by the burner 13, and then burned violently in the combustion chamber 12 to produce high-temperature flue gas. The heat released by combustion is transferred to the heat exchanger through the wall of the combustion chamber 12, heating the flowing cold water. The high-temperature flue gas enters the smoke hood 21 through the exhaust port of the combustion chamber 12, is accelerated by the exhaust fan 22, and is discharged through the exhaust pipe 23. Inside the exhaust pipe 23, the generator blades 31 are driven to rotate by the kinetic energy of the exhaust gas, driving the wind turbine 32 to generate electricity. The electrical energy is stored in the battery 41 and powers the control panel 42 and other components, realizing the conversion of exhaust gas kinetic energy into electrical energy. The control panel 42 monitors the ambient temperature in real time through a temperature detector. When the detected temperature is lower than the set threshold, a buzzer alarm is sounded and the user is notified through the display screen 421.

[0069] In summary, this embodiment of an energy-saving gas water heater, by adding a wind turbine blade 31 and a storage battery 41 inside the exhaust pipe 23 of the gas water heater, utilizes the kinetic energy of flue gas to convert and store electrical energy, recovering the kinetic energy of waste gas, reducing external power consumption, and thus saving energy and protecting the environment; at the same time, it ensures continuous standby of the machine, monitors the temperature in real time through the display panel, and sounds an alarm and flashes an anti-freeze indicator when the temperature is low, effectively reminding the user and ensuring the reliability of the anti-freeze function; finally, by coordinating the storage battery 41 with the external power supply and improving the dual power switching logic, it automatically switches when the storage battery 41 is low on power, improving the stability of the system power supply, and solving the problem of anti-freeze failure and energy waste caused by the reliance on external power supply in traditional water heaters.
