A smoke collecting hood is installed on the top of the heat exchanger. A condenser is installed on the top of the smoke collecting hood. The condenser is used for the first heat exchange between cold water and the flue gas generated inside the burner. The heat exchanger is used for the second heat exchange between cold water and the flue gas generated inside the burner;

[0006] A blower is installed on the inner side wall of the housing. The air outlet end of the blower is communicated with the air inlet end of the burner. A controller, a water pump, a valve, a proportional valve, an auxiliary electric heater, and a gas distributing rod are respectively arranged on one side of the blower.

[0016] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects:

[0017] The condensed water generated during the heat exchange process by the condenser is effectively collected and discharged by the condensate drain pipe, which not only prevents the waste of water resources, but also avoids the equipment damage or performance degradation that may be caused by the accumulation of condensed water. The double heat exchange design of the condenser and the heat exchanger reduces the heat energy emission in the waste gas. At the same time, the waste gas has been fully cooled before being discharged, reducing the impact on the environment.

[0018] By adopting a proportional valve and a controller to precisely control the gas supply amount, combined with recovering the heat in the flue gas in the condenser, the energy utilization rate is improved, and efficient combustion is achieved. Through the two heat exchange processes of the condenser and the heat exchanger, the heat generated by the gas combustion can be more fully utilized, improving the energy usage efficiency. The use of the water pump enables cold water to quickly enter the condenser and the heat exchanger for heat exchange. At the same time, through the cooperation of the temperature probe and the auxiliary electric heater, the temperature of the output hot water is ensured to be constant, meeting the bathing needs of users.

[0019] Through the precise control of the proportional valve, blower, air distribution rod, and burner, the system can adjust the ratio of gas to air according to demand, thus achieving efficient combustion and providing stable high-temperature gas. This not only helps maintain the high energy efficiency level of the equipment but also reduces energy waste and lowers the energy consumption cost.

[0020] Through the coordination of the water pump, valves, and multiple water pipes, the water flow into the heat exchanger and condenser can be precisely controlled to ensure a stable hot water supply under different usage scenarios, such as peak hours or low water consumption periods. This not only improves the intelligence and user experience of the gas water heater but also helps save water resources.

[0021] The condenser can condense the water vapor in the flue gas into water, reducing waste gas emissions. At the same time, it also recovers some heat energy, further improving energy efficiency, reducing energy consumption and environmental pollution. The air distribution rod is used to evenly control the flame, making the combustion more stable and avoiding equipment damage caused by local overheating, thus increasing the service life of the whole machine.

Embodiment

[0035] Please refer to Figures 1-9 , the present invention provides a technical solution: a structure of a new type of condensing gas instantaneous water heater, including a housing 1, a panel 4 is installed on one side of the housing 1, a burner 15 is installed on one side of the inner wall of the housing 1, the controller 8 controls the solenoid valve 25 to open, so that gas enters the inside of the gas distribution rod 13. At this time, the igniter inside the burner 15 ignites the gas ejected from the combustion nozzle. A heat exchanger 19 is installed on the top of the burner 15, and a smoke hood 16 is installed on the top of the heat exchanger 19 to collect the flue gas after gas combustion, so that the flue gas enters the inside of the smoke hood 16 and is conveyed to the inside of the condenser 17. A condenser 17 is installed on the top of the smoke hood 16. The condenser 17 is used for the first heat exchange between cold water and the flue gas generated inside the burner 15, and the heat exchanger 19 is used for the second heat exchange between cold water and the flue gas generated inside the burner 15;

[0036] A blower 14 is installed on the inner side wall of the housing 1. The air outlet end of the blower 14 is communicated with the air inlet end of the burner 15. A controller 8, a water pump 9, a valve 10, a proportional valve 11, an auxiliary electric heater 12 and a gas distributing rod 13 are respectively arranged on one side of the blower 14. A water flow detector is installed inside the valve 10. When the water flow is detected, the gas water heater starts to work. At the same time, a temperature probe is installed at the water inlet end of the auxiliary electric heater 12 for detecting the temperature of the heated water.

[0037] The gas inlet end of the gas distributing rod 13 is communicated with an electromagnetic valve 25. The gas inlet end of the electromagnetic valve 25 is communicated with the proportional valve 11. The gas inlet end of the proportional valve 11 is communicated with a gas inlet pipe 6. Three combustion chambers are arranged inside the gas distributing rod 13. A plurality of combustion nozzles are respectively located inside the three combustion chambers. During the combustion operation, the flames burn in an alternating interval manner, which can increase the total width of the flames and effectively reduce the area of the low-temperature region inside the combustion chamber during segmented combustion, thereby solving the problem of excessive condensate caused by too low temperature inside the burner 15. The gas outlet end of the gas distributing rod 13 is located inside the burner 15. A combustion nozzle is installed at the gas outlet end of the gas distributing rod 13. The controller 8 controls the proportional valve 11 and the blower 14 to input an appropriate gas-to-air ratio, so as to realize the orderly combustion of the flame inside the burner 15 and provide stable high-temperature gas.

[0038] The water inlet end of the valve 10 is communicated with a cold water inlet pipe 7. The water outlet end of the valve 10 is communicated with a third water pipe 22. The water outlet end of the third water pipe 22 is communicated with the water pump 9. Tap water enters the water pump 9. At this time, under the action of the water pump 9, the water is pumped through the second water pipe 21 into the condenser 17. The water outlet end of the water pump 9 is communicated with the second water pipe 21. The water outlet end of the second water pipe 21 is connected to one side of the water inlet end of the condenser 17. The cold water exchanges heat with the flue gas for the first time and is heated inside the condenser 17. The condensate generated after heat exchange in the condenser 17 is discharged through a condensate drain pipe 18. The water outlet end of the condenser 17 is communicated with a first water pipe 20. The water outlet end of the first water pipe 20 is connected to the water inlet end of the heat exchanger 19. The water outlet end of the heat exchanger 19 is communicated with a fourth water pipe 23.

[0039] The water outlet end of the auxiliary electric heater 12 is communicated with a fifth water pipe 24. The water inlet end of the auxiliary electric heater 12 is connected to the water outlet end of the fourth water pipe 23. The water outlet end of the fifth water pipe 24 is communicated with a hot water outlet pipe 5. The hot water outlet pipe 5, the gas inlet pipe 6 and the cold water inlet pipe 7 are all installed on one side of the bottom of the housing 1. The hot water outlet pipe 5 is connected to the water inlet end of the faucet in the room. The gas inlet pipe 6 is connected to the municipal gas. The cold water inlet pipe 7 is connected to the municipal tap water.

[0040] The outlet end of the condenser 17 is connected to a smoke exhaust pipe 3 fixed to one side of the top of the housing 1. An installation frame 2 is installed on one side of the housing 1. One side of the bottom of the water outlet end of the condenser 17 is connected to a condensate drain pipe 18. The output end of the controller 8 is electrically connected to the input ends of a water pump 9, a valve 10, a proportional valve 11, an auxiliary electric heater 12, a fan 14, and a solenoid valve 25 respectively. The heat exchanger 19 exchanges heat with the condenser 17. The high-temperature gas after the first heat exchange enters the condenser 17 through the smoke collecting hood 16, and undergoes a second heat exchange through the condenser 17. The finally lower-temperature exhaust gas is then output to the outside through the smoke exhaust pipe 3 of the condenser 17, and finally the constant-temperature hot water is output through the hot water outlet pipe 5.

[0041] Working principle or structural principle: When the gas instantaneous water heater is in use, gas enters the proportional valve 11 through the gas inlet pipe 6. Then the controller 8 controls the solenoid valve 25 to open, allowing the gas to enter the inner side of the gas distribution rod 13. At this time, the igniter inside the burner 15 ignites the gas ejected from the combustion nozzle. The flue gas generated by the ignited gas passes through the heat exchanger 19, the smoke collecting hood 16, the condenser 17, and the smoke exhaust pipe 3 in sequence, and finally is discharged to the outside through the pipe connected to one side of the smoke exhaust pipe 3.

[0042] At this time, the municipal tap water enters the inner side of the valve 10 through the cold water inlet pipe 7. Then, under the action of the third water pipe 22, the tap water enters the water pump 9. At this time, the water, under the action of the water pump 9, is pumped through the second water pipe 21 into the condenser 17. At this time, the cold water exchanges heat with the flue gas for the first time and is heated inside the condenser 17. The condensate generated after heat exchange in the condenser 17 is discharged through the condensate drain pipe 18. One end of the condensate drain pipe 18 is connected to a water pipe to discharge the generated condensate, and the condensate can be recycled.

[0043] When the cold water heated by the first heat exchange enters the inner side of the heat exchanger 19 under the action of the first water pipe 20, the water exchanges heat with the flame generated by the gas distribution rod 13 inside the burner 15 through the heat exchanger 19. The flue gas generated by the flame exchanges heat with the water inside the heat exchanger 19 and heats the water. At this time, hot water flows out from the water outlet end of the heat exchanger 19. The hot water is transported to the inner side of the auxiliary electric heater 12 under the action of the fourth water pipe 23. The temperature probe located in front of the auxiliary electric heater 12 detects the temperature of the heated water. When the water temperature meets the required temperature, the warm water enters the hot water outlet pipe 5 through the fifth water pipe 24, and the hot water outlet pipe 5 transports the water to the faucet through the water pipe.

[0044] When the temperature probe detects that the water temperature is low and does not meet the required temperature, at this time, the auxiliary electric heater 12 temporarily heats the water delivered by the fourth water pipe 23, and then outputs warm water with the required temperature through the fifth water pipe 24. At this time, the controller 8 controls the proportional valve 11 and the blower 14 to input an appropriate gas-air ratio, so as to realize the orderly combustion of the flame inside the burner 15, provide stable high-temperature gas, enable the heat exchanger 19 to exchange heat with the condenser 17, and the high-temperature gas after the first heat exchange enters the condenser 17 through the smoke collecting hood 16, and undergoes secondary heat exchange through the condenser 17. The finally lower-temperature exhaust gas is then output to the outside through the exhaust pipe 3 of the condenser 17, and finally the constant-temperature hot water is output through the hot water outlet pipe 5;

[0045] Through the cooperation of the water pump 9, the valve 10, the proportional valve 11, the auxiliary electric heater 12, the gas distribution rod 13, the blower 14, the burner 15, the smoke collecting hood 16 and the condenser 17, the heating time is effectively shortened and the water control function is increased. While meeting a better bathing experience, the gas distribution rod 13 is used to evenly control the combustion to generate condensate, increasing the service life of the whole machine.

[0046] In summary, the condensate generated by the condenser 17 during the heat exchange process is effectively collected and discharged by the condensate drain pipe 18, which not only prevents the waste of water resources, but also avoids equipment damage or performance degradation that may be caused by the accumulation of condensate. The double heat exchange design of the condenser 17 and the heat exchanger 19 reduces the heat energy emission in the exhaust gas. At the same time, the exhaust gas has been fully cooled before being discharged, reducing the impact on the environment.

[0047] The proportional valve 11 and the controller 8 are used to precisely control the gas supply volume, combined with the recovery of heat in the flue gas in the condenser 17, improving the energy utilization rate and realizing efficient combustion. Through the two heat exchange processes of the condenser 17 and the heat exchanger 19, the heat generated by gas combustion can be utilized more fully, improving the energy use efficiency. The use of the water pump 9 enables cold water to quickly enter the condenser 17 and the heat exchanger 19 for heat exchange. At the same time, through the cooperation of the temperature probe and the auxiliary electric heater 12, it is ensured that the temperature of the output hot water is constant, meeting the bathing needs of users;

[0048] Through the precise control of the proportional valve 11, the blower 14, the gas distribution rod 13 and the burner 15, the system can adjust the gas-air ratio according to the demand, so as to realize efficient combustion and provide stable high-temperature gas, which not only helps to maintain the high energy efficiency level of the equipment, but also reduces energy waste and the cost of energy consumption;

[0049] Through the cooperation of the water pump 9, the valve 10 and multiple water pipes, the water flow into the heat exchanger 19 and the condenser 17 can be precisely controlled, ensuring a stable hot water supply under different usage scenarios, such as peak hours or low water consumption periods. This not only improves the intelligence and user experience of the gas water heater but also helps to save water resources;

[0050] The condenser 17 can condense the water vapor in the flue gas into water, reducing the emission of waste gas. At the same time, it also recovers part of the heat energy, further improving the energy efficiency, reducing energy consumption and environmental pollution; The gas distributor rod 13 is used to evenly control the flame, making the combustion more stable, avoiding equipment damage caused by local overheating, and thus increasing the service life of the whole machine.
