Description

Technical Field

[0001] The present invention relates to the technical field of liquid water heaters, and in particular to a liquid fuel water heater based on a zoned combustion technology. Background Art

[0002] At present, liquid fuel water heaters are devices that use liquid fuel (such as oil, liquefied natural gas or biodiesel, etc.) as energy to generate heat through combustion to heat water. This type of water heater is usually designed with a combustion system, heat exchanger and control system to ensure that the fuel burns efficiently and safely, and transfers the generated heat energy to water to meet household or industrial hot water needs.

[0003] Traditional fuel water heaters, under certain operating scenarios, pose a potential safety hazard that cannot be ignored. When the user disconnects the water flow and expects the water heater to stop heating, a problem quietly emerges: due to limitations in the design or operating mechanism, a small amount of liquid fuel often remains in the combustion chamber. This fuel does not immediately extinguish with the interruption of the water flow, but continues to burn. This subtle but critical process, although seemingly insignificant, actually hides risks. The residual fuel will continue to release heat during the continuous combustion process, causing the water temperature in the pipe to rise sharply, sometimes even reaching 80 degrees or even higher. In such a high temperature state, if the user is not fully prepared, once the faucet is turned on again, boiling hot water will gush out instantly, which can easily cause scalding accidents, especially for children and the elderly in the family, posing a considerable threat. Summary of the Invention

[0004] The present invention proposes a liquid fuel water heater based on zoned combustion technology, which solves the problems of insufficient thermal energy utilization and abnormal water temperature in related technologies.

[0006] As a preferred embodiment of the present invention, an air outlet is fixedly connected to the top of the preheating recovery device. A multi-stage pipeline is fixedly connected inside the preheating recovery device. A plurality of connecting shafts are fixedly connected inside the preheating recovery device and are arranged at equal intervals in an array. A partition plate is jointly connected to the outer circumferential surfaces of every two connecting shafts.

[0007] As a preferred embodiment of the present invention, the multi-stage pipeline is a secondary multi-stage connection of pipelines arranged in three layers from top to bottom in an array. The partition plate is arranged between every two pipelines. The shape of the partition plate is "C"-shaped. The middle partition plate and the partition plates on both sides are placed in opposite directions, forming an "S"-shaped arrangement. The partition plate can increase the heat dissipation area of the radiator and increase the contact area with the high-temperature airflow.

[0008] As a preferred embodiment of the present invention, a connecting pipeline is jointly connected to the water outlet and the water inlet. The connecting pipeline is connected to the water inlets and outlets of the solenoid valve, the circulating water pump, the preheating recovery device, the secondary water tank, the heat exchanger, and the one-way valve. The water flow passes through the solenoid valve, the circulating water pump, the preheating recovery device, the secondary water tank, the heat exchanger, and the one-way valve. The water flow circularly absorbs heat and heats the water flow, and quickly absorbs and uses the excess thermal radiant energy.

[0009] As a preferred embodiment of the present invention, a part of the connecting pipeline passes through the interior of the secondary water tank. A rotating shaft is rotatably installed in the connecting pipeline inside the secondary water tank. A runner is fixedly connected to one end of the rotating shaft. A driving bevel gear is fixedly connected to the other end of the rotating shaft. A follower shaft is rotatably installed inside the secondary water tank. A follower bevel gear is fixedly connected to one end of the follower shaft. The driving bevel gear meshes with the follower bevel gear. A rotating gear is fixedly connected to the other end of the follower shaft. A rotating disk is rotatably installed inside the secondary water tank. A meshing gear is fixedly connected to the bottom of the rotating disk. The rotating gear meshes with the meshing gear. A plurality of turbulator vanes are fixedly connected to the top of the rotating disk in a circumferentially evenly distributed manner. Through the flow of the water flow, the rotation of the turbulator vanes is driven, so that the water flow inside the secondary water tank is disturbed and mixed, accelerating its heating speed.

[0010] As a preferred embodiment of the present invention, a plurality of auxiliary balls are rotatably installed inside the rotating disk in a circumferentially evenly distributed manner. A plurality of pores are arranged in an array at equal intervals on the turbulator vanes.

[0011] As a preferred embodiment of the present invention, a burner is installed inside the ion combustor. An installation disc is fixedly connected to the top of the burner. A silencer is fixedly connected to the top of the installation disc. A fire-dividing fin is fixedly connected to the top of the silencer. A wind chamber is installed at the top of the burner. A filter felt is arranged at the bottom of the wind chamber. Utilizing the temperature generated by the primary combustion in the primary combustion chamber of the ion combustor, with the cooperation of the combustion chamber fan, air enters through the cyclone intake cylinder of the ion combustor, high-temperature vaporizes the liquid fuel, and stably burns and fully vaporizes in the secondary combustion chamber of the combustion cylinder of the ion combustor. It burns and generates heat sufficiently in the combustion chamber cavity, enabling the liquid fuel to burn fully. The combustion device no longer directly heats through flames, but after sufficient combustion, the fuel heats the heat exchanger through thermal radiation and high-temperature gas. The high-temperature flue gas heats the water flowing from the secondary water tank through the heat exchanger.

[0012] As a preferred embodiment of the present invention, a fuel pipe is provided on the fuel pump, and the output end of the fuel pipe is arranged at the bottom of the ion combustor.

[0013] The working principle and beneficial effects of the present invention are as follows:

[0014] 1. Through the arrangement of structures such as the preheating recovery device and the heat exchanger in the present invention, water flows through the solenoid valve, circulation water pump, preheating recovery device, secondary water tank, heat exchanger, and check valve. At this time, the water circulates and absorbs heat, heats the water flow, and quickly absorbs and uses the excess thermal radiation energy, avoiding heat loss and ensuring the normal temperature inside the water heater.

[0015] 2. Through the arrangement of structures such as the runner and flow disturbing blades in the present invention, when the water flow passes through the inside of the secondary water tank and passes through the runner, the runner rotates. The rotation of the runner causes the flow disturbing blades to rotate, and the rotation of the flow disturbing blades disturbs and mixes the water flow inside the secondary water tank, accelerating its heating speed.

[0016] 3. Through the arrangement of structures such as the multi-stage pipeline and the partition plate in the present invention, when the preheating recovery device is in use, the water flow passes through the multi-stage pipeline, and the flue gas is output along the partition plate. The multi-stage pipeline is arranged from top to bottom, and the partition plate is in an "S" shape, enabling the flue gas to heat the water flow from a relatively low temperature when entering to a relatively high temperature when flowing out. At the same time, the height difference of the water flow can also cool the flue gas in multiple stages, improving the water flow heating speed and the flue gas cooling speed.

Detailed implementation mode

[0031] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0032] Embodiment:

[0033] As Figures 1 to 12 shown, this embodiment proposes a liquid fuel water heater based on the partition combustion technology, including a housing 101. Inside the housing 101, a combustion chamber main body 4 is installed. On the top of the combustion chamber main body 4, a heat exchanger 3 is installed. On the top of the heat exchanger 3, an exhaust fan 1 and a preheating recovery device 2 are respectively installed. On the outer peripheral surface of the combustion chamber main body 4, a secondary water tank 5 is fixedly connected. At the bottom of the combustion chamber main body 4, an ion combustion body 6 is installed. At the bottom of the ion combustion body 6, a thermocouple 7 and a combustion chamber blower 8 are respectively installed. Inside the housing 101, a check valve 9, a circulation water pump 10, a solenoid valve 11, and an oil pump 12 are respectively installed. One end of the check valve 9 is fixedly connected to a water outlet 13. The bottom of the solenoid valve 11 is fixedly connected to a water inlet 15. The bottom of the oil pump 12 is fixedly connected to an oil inlet 14. Through the setting of structures such as the preheating recovery device 2 and the heat exchanger 3, water flows through the solenoid valve 11, the circulation water pump 10, the preheating recovery device 2, the secondary water tank 5, the heat exchanger 3, and the check valve 9. At this time, the water circulates and absorbs heat, heats the water, and quickly absorbs and uses the excess thermal radiant energy, avoiding heat loss and ensuring the normal temperature inside the water heater.

[0034] As Figures 5 to 6 shown, the top of the preheating recovery device 2 is fixedly connected to an air outlet 21. Inside the preheating recovery device 2, a multi-stage pipeline 22 is fixedly connected. Inside the preheating recovery device 2, a number of connecting shafts 24 are fixedly connected and distributed at equal intervals in an array. On the outer peripheral surfaces of every two connecting shafts 24, a partition plate 23 is jointly connected.

[0035] As Figures 5 to 6As shown, the multi-stage pipeline 22 is a pipeline multi-stage connection secondary with three-layer array distribution from top to bottom. The partition plate 23 is arranged between every two pipelines. The shape of the partition plate 23 is "C" shaped. The middle partition plate 23 and the partition plates 23 on both sides are placed in opposite directions, forming an "S" shaped arrangement. The partition plate 23 can increase the heat dissipation area of the radiator and increase the contact area with the high-temperature airflow. Through the settings of structures such as the multi-stage pipeline 22 and the partition plate 23, when the preheating recovery device 2 is in use, water flows through the multi-stage pipeline 22, and the flue gas is output along the partition plate 23. The multi-stage pipeline 22 is arranged from top to bottom, and the partition plate 23 is "S" shaped, enabling the flue gas to heat the water flow from a relatively low temperature when entering to a relatively high temperature when flowing out, and the height difference of the water flow can also cool the flue gas in multiple stages, improving the water flow heating speed and the flue gas cooling speed.

[0036] As Figures 1 to 7 shown, a connecting pipeline is commonly connected to the water outlet 13 and the water inlet 15. The connecting pipeline is connected to the water inlets 15 and water outlets 13 of the solenoid valve 11, the circulation water pump 10, the preheating recovery device 2, the auxiliary water tank 5, the heat exchanger 3, and the check valve 9. The water flow passes through the solenoid valve 11, the circulation water pump 10, the preheating recovery device 2, the auxiliary water tank 5, the heat exchanger 3, and the check valve 9. The water flow circularly absorbs heat and heats the water flow, and quickly absorbs and uses the excess thermal radiant energy.

[0037] As Figures 7 to 10 shown, a part of the connecting pipeline passes through the interior of the auxiliary water tank 5. A rotating shaft 51 is rotatably installed in the connecting pipeline inside the auxiliary water tank 5. One end of the rotating shaft 51 is fixedly connected to a runner 52, and the other end of the rotating shaft 51 is fixedly connected to a driving bevel gear 53. A follower shaft 54 is rotatably installed inside the auxiliary water tank 5. One end of the follower shaft 54 is fixedly connected to a follower bevel gear 55. The driving bevel gear 53 meshes with the follower bevel gear 55. The other end of the follower shaft 54 is fixedly connected to a rotating gear 56. A rotating disc 57 is rotatably installed inside the auxiliary water tank 5. The bottom of the rotating disc 57 is fixedly connected to an engaging gear 571. The rotating gear 56 meshes with the engaging gear 571. The top of the rotating disc 57 is fixedly connected with a plurality of turbulator blades 573 evenly distributed in a circumferential manner. Through the flowing of the water flow, the rotation of the turbulator blades 573 is driven, enabling the water flow inside the auxiliary water tank 5 to be disturbed and mixed, accelerating its heating speed. Through the settings of structures such as the runner 52 and the turbulator blades 573, when the water flow passes through the interior of the auxiliary water tank 5, when the water flow passes through the runner 52, the runner 52 rotates, the rotation of the runner 52 causes the turbulator blades 573 to rotate, and the rotation of the turbulator blades 573 causes the water flow inside the auxiliary water tank 5 to be disturbed and mixed, accelerating its heating speed.

[0038] As Figures 7 to 10As shown, several auxiliary balls 572 evenly distributed in a circle are rotatably installed inside the rotating disk 57, and several fine holes are arranged on the spoiler blade 573 at equal intervals in an array.

[0039] As Figures 3 to 12 shown, a burner 64 is installed inside the ion combustor 6. The top of the burner 64 is fixedly connected to a mounting plate 63. The top of the mounting plate 63 is fixedly connected to a silencer 62. The top of the silencer 62 is fixedly connected to a flame dividing fin 61. A wind cavity 65 is installed at the top of the burner 64. A filter felt 66 is arranged at the bottom of the wind cavity 65. Using the temperature generated by the primary combustion in the primary combustion chamber of the ion combustor 6, with the cooperation of the combustion chamber fan 8, air is introduced through the cyclone intake cylinder of the ion combustor 6, the liquid fuel is vaporized at high temperature, and it burns stably and is fully vaporized in the secondary combustion chamber of the combustion cylinder of the ion combustor ⑥, and burns and generates heat sufficiently in the combustion chamber cavity, so that the liquid fuel is fully burned. The combustion device no longer directly heats through the flame, but after full combustion, the fuel heats the heat exchanger 3 through thermal radiation and high-temperature gas. The high-temperature flue gas heats the water flowing from the secondary water tank 5 through the heat exchanger 3.

[0040] As Figures 1 to 12 shown, a fuel pipe is provided on the oil pump 12, and the output end of the fuel pipe is arranged at the bottom of the ion combustor 6.

[0041] In this embodiment, when the device is in use, the solenoid valve 11 is opened, the circulating water pump 10 is started, and water flows in from the water inlet 15. At this time, the oil pump 12 and the ion combustor 6 are also started synchronously. The oil pump 12 inputs the liquid combustible, and the combustible is input to the thermocouple 7 for ignition. At this time, the combustion chamber fan 8 and the exhaust fan 1 are started. The rotation of the combustion chamber fan 8 and the exhaust fan 1 sends the flame and flue gas into the air chamber 65. When sending, the unburned completely flame and flue gas are intercepted by the filter felt 66. Through the transportation of the air chamber 65, the flame is sent to the flame dividing fin 61 for flame output to heat the combustion chamber main body 4. When heating, the silencer 62 silences it. When the combustion chamber main body 4 is heated, thermal radiation will be generated on the ion combustor 6, and the flue gas, because of the start of the combustion chamber fan 8 and the exhaust fan 1, first passes through the heat exchanger 3 and then is output by the preheating recovery device 2. At this time, water flows from the connecting pipe into the multi-stage pipe 22 in the preheating recovery device 2. The water flows through the multi-stage pipe 22, and the flue gas is output along the partition plate 23. The multi-stage pipe 22 is arranged from top to bottom, and the partition plate 23 is in an "S" shape, so that the flue gas can heat the water from the relatively low temperature when entering to the relatively high temperature when flowing out, and the height difference of the water flow can also cool the flue gas in multiple stages, improving the heating speed of the water flow and the cooling speed of the flue gas. After the water flow flows out of the multi-stage pipe 22, it enters the auxiliary water tank 5. The water flows into the auxiliary water tank 5 from the bottom. Because the auxiliary water tank 5 is closely attached to the ion combustor 6, the water in the auxiliary water tank 5 is heated by the thermal radiation of the ion combustor 6 and flows out from the top of the auxiliary water tank 5. When the water flow passes through the runner 52, it drives the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, it drives the driving bevel gear 53 to rotate. The driving bevel gear 53 drives the follower shaft 54 to rotate through the engagement with the follower bevel gear 55. When the follower shaft 54 rotates, through the rotation of the rotating gear 56 and the meshing gear 571, the rotating disc 57 rotates. The rotation of the rotating disc 57 is assisted by the auxiliary ball 572. The rotation of the rotating disc 57 makes the spoiler blade 573 rotate. The spoiler blade 573 is provided with fine holes. The setting of the fine holes can reduce the resistance of the spoiler blade 573. The rotation of the spoiler blade 573 makes the water flow inside the auxiliary water tank 5 be disturbed and mixed, accelerating its heating speed. After the water flow flows out of the auxiliary water tank 5, it enters the inside of the heat exchanger 3. The circulating pipe inside the heat exchanger 3 is arranged in an "S" shape. When the flue gas passes by, when the water flow flows through the "S"-shaped circulating pipe, it can stay in the heat exchanger 3 for a long time, so that the heating of the flue gas is more comprehensive. After the heated water flow flows out of the heat exchanger 3, it flows out from the water outlet 13 at the check valve 9. When the device stops heating, the check valve 9 is closed, and the circulating water pump 10 is started, so that the water flow circulates inside the device, and the residual flue gas is utilized for heat energy recovery, avoiding heat loss and ensuring the normal temperature inside the water heater at the same time.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
