Description

Technical Field

[0001] This technical solution relates to a liquid fuel stove, and more particularly to a commercial environmentally friendly liquid fuel stove. Background Technology

[0002] In the commercial cooking sector, such as restaurants, canteens, and food processing workshops, the stable operation, energy efficiency, and safety performance of cooking equipment directly impact production efficiency and operating costs. Among these, the commercial stove, as a core piece of equipment, is particularly crucial. Currently, most mainstream commercial stoves on the market use natural gas as their primary energy source. While these gas-fired commercial stoves can meet basic cooking needs under normal gas supply conditions, they suffer from numerous unavoidable limitations in practical applications, causing significant challenges to commercial cooking activities. These limitations are as follows: Firstly, gas supply is unstable in some application scenarios. Gas supply is easily affected by various factors such as pipeline construction and regional planning. In some remote areas, temporary commercial sites where gas pipelines are not covered, and areas with unstable gas supply, there is an urgent need for a cooking method that can replace gas stoves at a lower cost. Secondly, the flame performance is insufficient to meet commercial demands. Commercial cooking requires high levels of flame temperature, intensity, and stability. For example, stir-frying and quick-cooking require a strong flame to rapidly raise the temperature of the pan to ensure the taste and nutritional value of the ingredients. Existing commercial stoves, especially non-gas alternatives (such as traditional electric stoves and ordinary gas stoves), generally suffer from insufficient flame power, failing to meet the efficient and rapid heating requirements of commercial cooking and thus unable to meet the high-intensity usage demands during peak dining hours. Third, the energy efficiency is low and there are safety hazards. During operation, only a portion of the heat generated by the flame in existing stoves is used to heat the bottom of the pot; a large amount of heat is lost to the air around the stove, resulting in significant energy waste and excessively high surface temperatures, which can easily cause burns to operators. Although some improved stoves have attempted to incorporate insulation measures, they have failed to effectively recover and utilize the lost heat, and the energy waste problem persists.

[0003] Fourth, the level of intelligence is low. Existing stoves mostly require manual operation for functions such as water replenishment and water temperature control, resulting in a low level of intelligence. This not only increases the intensity of manual labor but also makes it difficult to guarantee the accuracy and stability of water temperature control, further affecting ease of use and energy efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a commercial stove that can replace a gas stove, featuring stable operation, flame power sufficient for commercial needs, high energy efficiency, good safety performance, and a high degree of intelligence. This addresses the problems of limited energy supply, insufficient flame performance, energy waste, poor safety, and low intelligence in existing technologies. The specific solution is as follows.

[0005] A commercial environmentally friendly liquid fuel stove, including a hollow stove body, is characterized in that a blower, a temperature control display, an igniter, an atomizer controller, and an oil pump are fixed inside the stove body, and a stove platform is fixed with an opening on the top surface of the stove body, with a stove core fixed in the center of the stove platform. The stove platform is platform-shaped and surrounds the stove core. The inside of the stove platform is a hollow water storage tank. The water storage tank is equipped with a water inlet pipe and a water outlet pipe. The water outlet pipe is equipped with a solenoid valve. The inner wall of the stove platform has a smoke inlet and is connected to a flue. The flue passes through the water storage tank and extends to the outside of the stove body. The ignition needle of the igniter (vegetable oil ignition controller) is connected to and placed into the ignition hole of the furnace core through a wire. The ignition control wire of the igniter is connected to the atomizing controller. Some igniters are also equipped with a power cord, which is directly connected to the power switch. The ignition control line of the atomizer is connected to the igniter, the electromagnetic pump line of the atomizer is connected to the oil pump, the input end of the oil pump is connected to the oil tank, the output end of the oil pump is equipped with an oil spray head and is placed in the oil spray hole of the furnace core, the fan line of the atomizer is connected to the blower, the air outlet of the blower is connected to the air inlet of the furnace core, and the power line of the atomizer is connected to the power switch. The output line of the temperature control display is connected to the solenoid valve, and the end of the probe line is a temperature sensor located at the outlet of the water storage tank. Its power line is connected to the power switch.

[0006] The inner wall of the furnace platform is inverted conical, and a ring-shaped mounting bracket is provided at the bottom. The furnace core is fixed to the center of the furnace platform through the mounting bracket.

[0007] The furnace core structure includes a cylindrical base with an oil spray hole and an ignition hole at the bottom. An air inlet is opened on the side wall of the base. A cylindrical cover box is placed inside the base. An oil spray channel is opened at the center of the top of the cover box. A cylindrical air box is snapped on top of the cover box. A circular hole matching the oil spray channel is provided at the bottom of the air box. Air holes are provided on the side wall of the air box. The top of the air box is open and covered with a cover plate. The cover plate is star-shaped and has multiple vertical ventilation gaps distributed around it at intervals. A tubular placement seat is provided above the cover plate, and a horn-shaped reflector is above the placement seat.

[0008] The reflector disc blades are arranged in a ring with multiple ridges, each ridge has a hole, and there are protrusions between the ridges.

[0009] The inlet and outlet pipe joints are located diagonally opposite each other in the water storage tank. This increases the water flow path, ensuring that the cold water is fully heated as it circulates clockwise or counterclockwise.

[0010] The flue includes a heat exchange pipe installed inside the water storage tank and a flue outlet pipe outside the water storage tank.

[0011] The heat exchange tube is annular and is interrupted by a baffle in an arc-shaped section. The flue gas inlet is connected to one side of the baffle, and the flue gas outlet is connected to the other side of the baffle. This design increases the travel distance of the high-temperature gas generated during combustion, requiring it to circulate completely before leaving the heat exchange tube, thus improving heat exchange efficiency. The heat exchange tube can also be configured as a spiral shape.

[0012] The outer end of the water outlet pipe is connected to an insulated water tank, which uses a water pump to deliver hot water to the water-using equipment.

[0013] The control panels for the temperature display, atomization controller, and power switch are located on the front panel of the stove for easy operation.

[0014] The stove body is provided with a back panel at the rear, and the smoke outlet pipe extends from the stove body to the back panel interlayer and is discharged from the top of the back panel. The end of the smoke outlet pipe is covered with a smoke hood.

[0015] Compared with the prior art, this technical solution achieves the following technical effects. 1. Replaces gas stoves, providing stable heat. When a stable gas supply is unavailable in commercial settings, this device can solve the heat supply problem. The fuel used in this device is vegetable oil, which offers three advantages over other alternatives (such as alcohol-based portable gas stoves, liquefied natural gas cylinders, etc.): affordability, enhanced safety, and stronger heat output. 2. It saves energy and improves heat utilization efficiency. Existing stove flames typically only act on the bottom of the pot for cooking. This technical solution fully utilizes the waste heat generated around the flame and from the high-temperature gases to heat water, saving energy and aligning with the direction of green development.

[0016] 3. This device is safer. Firstly, environmentally friendly liquid fuel cannot be ignited in its liquid state and must be atomized by an oil mist nozzle before it can burn. This allows the gas stove to efficiently cut off the flame source in emergencies, making it safer than alcohol and liquid natural gas, and it is less volatile and less prone to spreading. Secondly, the hot water in the stove automatically drains out when it reaches 55°C, ensuring that the stove and surrounding area never reach temperatures that could burn a person. This prevents operators from accidentally touching the hot stove and causing burns during tasks such as adding ingredients, cleaning, or adjusting cookware, and also prevents premature aging of wiring, seals, and other components around the stove due to high temperatures.

[0017] 4. This device is multifunctional and highly intelligent. In commercial settings, large amounts of hot water are consumed for tasks such as washing ingredients, disinfecting tableware, and providing domestic water for employees. This device integrates cooking, waste heat heating and storage, automatic control, and safety protection. It not only meets the demand for large amounts of hot water but also fully utilizes the automatic control functions of the combustion controller and atomizing controller to monitor the water and oil circuits, making operation more intelligent and convenient. It also reduces the cost of purchasing separate water heating equipment and the space occupied in the kitchen, making it highly practical. Attached Figure Description

Detailed Implementation

[0020] Example 1, see appendix Figure 1-7 A commercial environmentally friendly liquid fuel stove, comprising a hollow stove body 1, characterized in that a blower 10, a temperature control display 2, an igniter 11, a vegetable oil ignition controller, an atomizing controller 3, and an oil pump 7 are fixed inside the stove body 1, and a stove platform 5 is fixed with an opening on the top surface of the stove body 1, with a stove core 6 fixed in the center of the stove platform 5. The stove platform 5 is in the shape of a platform and surrounds the stove core 6. The interior of the stove platform 5 is a hollow water storage tank 5-1. The water storage tank 5-1 is equipped with a water inlet pipe 16 and a water outlet pipe 18. The water outlet pipe 18 is equipped with a solenoid valve 8. The inner wall of the stove platform 5 has a smoke inlet 9-1 and is connected to a flue 9. The flue 9 passes through the water storage tank 5-1 and extends to the outside of the stove body 1. The ignition needle 11-1 of the igniter 11 is connected to and placed into the ignition hole of the furnace core 6 via a wire. The ignition control wire of the igniter 11 is connected to the atomizing controller 3. Some igniters 11 are also equipped with a power cord, which is directly connected to the power switch 4. The ignition control line of the atomizing controller 3 is connected to the igniter 11, the electromagnetic pump line of the atomizing controller 3 is connected to the oil pump 7, the input end of the oil pump 7 is connected to the oil tank 12, the output end of the oil pump 7 is equipped with an oil spray head 7-1 and is placed in the oil spray hole of the furnace core 6, the fan line of the atomizing controller 3 is connected to the blower 10, the air outlet of the blower 10 is connected to the air inlet of the furnace core 6, and the power line of the atomizing controller 3 is connected to the power switch 4. The output line of the temperature control display 2 is connected to the solenoid valve 8, and the end of the probe line is a temperature sensor 14, which is set at the outlet of the water tank 5-1, and its power line is connected to the power switch 4.

[0021] The inner wall of the furnace platform 5 is inverted cone-shaped, and a ring mounting bracket 5-2 is provided at the bottom. The furnace core 6 is fixed to the center of the furnace platform 5 through the mounting bracket 5-2.

[0022] The furnace core 6 structure includes a cylindrical base 6-3, with an oil spray hole and an ignition hole at the bottom of the base 6-3. An air inlet 6-3-1 is opened on the side wall of the base 6-3. A cylindrical cover box 6-4 is placed inside the base 6-3. An oil spray channel is opened at the center of the top of the cover box 6-4. A cylindrical air box 6-5 is snapped on the top of the cover box 6-4. A round hole matching the oil spray channel is provided at the bottom of the air box 6-5. An air hole 6-5-1 is provided on the side wall of the air box 6-5. The top of the air box 6-5 is open and covered with a cover plate 6-6. The cover plate 6-6 is star-shaped, with multiple vertically penetrating ventilation gaps 6-6-1 distributed around its perimeter. A tubular placement seat 6-2 is provided above the cover plate 6-6. A trumpet-shaped reflector 6-1 is above the placement seat 6-2.

[0023] The reflector disk 6-1 has multiple ridges 6-1-2 distributed in a ring on its blades. The ridges 6-1-2 have holes and protrusions 6-1-1 are provided between the ridges 6-1-2.

[0024] The connectors of the inlet pipe 16 and the outlet pipe 18 are respectively located diagonally opposite each other in the water storage tank 5-1. This increases the water flow path, ensuring that the cold water is fully heated as it circulates clockwise or counterclockwise.

[0025] The flue 9 includes a heat exchange pipe 9-2 installed inside the water storage tank 5-1 and a flue outlet pipe 9-3 outside the water storage tank 5-1.

[0026] The heat exchange tube 9-2 is annular and is interrupted by a partition in an arc-shaped section. The flue gas inlet 9-1 connects to one side of the partition, and the flue gas outlet 9-3 connects to the other side of the partition. This design increases the travel distance of the high-temperature gas generated by combustion, requiring it to circulate once before leaving the heat exchange tube 9-2, thus improving heat exchange efficiency. The heat exchange tube 9-2 can also be spiral-shaped. The outer end of the water outlet pipe 18 is connected to an insulated water tank 15, which uses a water pump 13 to deliver hot water to the water-using equipment.

[0027] The operation panels for the temperature control display 2, atomization controller 3, and power switch 4 are located on the front panel of the stove body 1 for easy operation.

[0028] The stove body 1 is provided with a back plate at the rear, and the smoke pipe 9-3 extends from the stove body 1 to the back plate interlayer and is discharged from the top of the back plate. The end of the smoke pipe 9-3 is covered with a smoke hood.

[0029] The specific models are as follows: (1) The temperature control display model is W1411, which has five built-in buttons: stop temperature +, stop temperature -, switch / set, start temperature +, and start temperature -, as well as three display screens for stop temperature, time, and start temperature. The temperature control display can set the start temperature by setting the start temperature + and - buttons, thereby sending a start signal to the solenoid valve, and can also set the stop temperature by setting the stop temperature + and - buttons. The temperature source is obtained through a temperature sensor; (2) The atomizing controller model is N series (N8) atomizing controller, which has built-in ignition wire, electromagnetic pump wire, fan wire, and power cord; (3) The igniter model is vegetable oil ignition controller, which is equipped with two ignition needles and one control wire. Some high-power igniters, blowers, and oil pumps will be equipped with independent power cords, which only need to be connected to the power switch.

[0030] The principle behind this embodiment is as follows: Turn on the power switch: (1) The temperature control display is powered on and the temperature of the water outlet of the water storage tank is obtained through the temperature sensor; (2) The atomization controller is powered on and provides power and signal to the igniter, oil pump and blower; (3) The igniter is powered on and the ignition needle starts to generate electric sparks; (4) The oil pump is powered on and delivers atomized fuel to the furnace core. The furnace core obtains atomized fuel and sparks and has the conditions for combustion, and the flame is turned on; (5) The blower is powered on and delivers air to the furnace core, so that the flame is turned upward.

[0031] 2. Cooking: By increasing the power of the oil pump and blower through the atomization controller, a large amount of fuel and air (containing oxygen) are continuously delivered to the furnace core, resulting in a very strong flame that meets the needs of commercial cooking.

[0032] 3. Waste heat utilization: While the flames are burning and heating the bottom of the pot, the heat generated also heats the inner wall of the furnace, which in turn heats the water in the water storage tank. At the same time, the high-temperature gas generated will enter the heat exchange tube through the flue gas inlet and further heat the water around the heat exchange tube, and finally be discharged through the flue gas outlet.

[0033] 4. Hot water management: After the water in the storage tank is continuously heated: (1) When the preset start temperature (e.g., 55°C) of the temperature control display is reached, the temperature sensor sends a signal to the temperature control display and opens the solenoid valve, and the hot water in the storage tank is squeezed out by the tap water in the inlet pipe; (2) When the hot water in the storage tank is discharged and cold water is filled, and the temperature drops to the stop temperature (e.g., 45°C), the temperature sensor sends a signal to the temperature control display and closes the solenoid valve, and the cold water in the storage tank continues to be heated.

[0034] The obtained hot water can be used for washing vegetables, dishes, pots, and replenishing pots, as well as for domestic use such as bathing and underfloor heating. This device features an insulated water tank at the outlet pipe for hot water storage, and a water pump further enhances its practicality by delivering the hot water to other water-using devices.

[0035] However, it should be noted that: (1) the inlet and outlet pipe joints of the water storage tank are set at opposite corners of the water storage tank, which can increase the water flow path and make the cold water heat up better and more fully during the process from the inlet pipe to the outlet pipe, avoiding dead corners; (2) the end of the outlet pipe extends upward to the top inside the water storage tank. Because the density of hot water is less than that of cold water, cold water is usually at the bottom and hot water is at the top, which can make the hot water discharged in an orderly manner according to the temperature.

[0036] 5. For further convenience, a heat preservation pot and a water tap can be added to the stove. The water tap can be connected to tap water, or hot water can be drawn from the outlet pipe through a three-way valve. The stove flame is strong and is usually used as a wok. The heat preservation pot stores clean water (or hot water) and is often used to replenish the water in the wok. Users can set it to one wok and one heat preservation pot (one wok and one heat preservation pot), one wok and two heat preservation pots, or two woks and two heat preservation pots as needed.

[0037] Compared with the prior art, this technical solution achieves the following technical effects. 1. Replaces gas stoves, providing stable heat. When a stable gas supply is unavailable in commercial settings, this device can solve the heat supply problem. The fuel used in this device is vegetable oil, which offers three advantages over other alternatives (such as alcohol-based portable gas stoves, liquefied natural gas cylinders, etc.): it is more economical, safer, and provides stronger heat. (1) Economical and affordable: Vegetable fuel, also known as environmentally friendly liquid fuel, is usually refined from renewable resources. Its procurement cost is lower than that of bottled natural gas, and its storage cost is also low. Unlike natural gas, it does not require high-pressure steel cylinders, nor does it require a separate fireproof storage area like alcohol, thus saving equipment and site costs. In addition, its calorific value per unit volume is higher than that of alcohol, making it less likely to be wasted. (2) Safer: Environmentally friendly liquid fuel cannot be ignited in its liquid state and must be atomized by an oil mist nozzle before it can burn. This allows the gas stove to efficiently cut off the fire source in an emergency, making it safer than alcohol and liquid natural gas, as it is less volatile and less likely to spread. (3) Strong firepower: The environmentally friendly vegetable fuel has a high calorific value, and its firepower is effectively enhanced with the help of this device: As attached Figure 2 As shown, when the fuel injector continuously delivers fuel for combustion, the strong airflow from the air inlet enters the gap between the base and the air box, and flows upward through the air hole into the air box. The negative pressure generated inside the air box draws the oil mist flame inside the cover box upward for combustion. The oil mist flame then passes through the ventilation gap on the side of the cover plate and is delivered upward, generating a powerful flame to heat the pot.

[0038] The cover allows the oil mist flame to point upwards and protects other parts of the burner core from oil mist contamination, extending the lifespan of the burner core. Technicians can configure the air vents to be tangential and the ventilation gaps to be beveled as needed, resulting in a spiral-rising flame that is more conducive to unobstructed fire path. The reflector is horn-shaped, which can effectively concentrate and reflect heat energy to save fuel and also prevent fuel from splashing into the burner, extending the lifespan of the stove.

[0039] 2. It saves energy and improves heat utilization efficiency. Existing stove flames typically only act on the bottom of the pot for cooking. This technical solution fully utilizes the waste heat generated around the flame and from the high-temperature gases to heat water, saving energy and aligning with the direction of green development.

[0040] 3. This device is safer. Firstly, environmentally friendly liquid fuel cannot be ignited in its liquid state and must be atomized by an oil mist nozzle before it can burn. This allows the gas stove to efficiently cut off the flame source in emergencies, making it safer than alcohol and liquid natural gas, and it is less volatile and less prone to spreading. Secondly, the hot water in the stove automatically drains out when it reaches 55°C, ensuring that the stove and surrounding area never reach temperatures that could burn a person. This prevents operators from accidentally touching the hot stove and causing burns during tasks such as adding ingredients, cleaning, or adjusting cookware, and also prevents premature aging of wiring, seals, and other components around the stove due to high temperatures.

[0041] 4. This device is multifunctional and highly intelligent. In commercial settings, large amounts of hot water are consumed for tasks such as washing ingredients, disinfecting tableware, and providing domestic water for employees. This device integrates cooking, waste heat heating and storage, automatic control, and safety protection. It not only meets the demand for large amounts of hot water but also fully utilizes the automatic control functions of the combustion controller and atomizing controller to monitor the water and oil circuits, making operation more intelligent and convenient. It also reduces the cost of purchasing separate water heating equipment and the space occupied in the kitchen, making it highly practical.

[0042] Example 2, see appendix Figure 8-9 A commercial environmentally friendly liquid fuel stove, including a hollow stove body, characterized in that a blower, a temperature control display, an igniter, an atomizer controller, and an oil pump are fixed inside the stove body, and a stove platform is fixed with an opening on the top surface of the stove body, with a stove core fixed in the center of the stove platform. The stove platform is platform-shaped and surrounds the stove core. The inside of the stove platform is a hollow water storage tank. The water storage tank is equipped with a water inlet pipe and a water outlet pipe. The water outlet pipe is equipped with a solenoid valve. The inner wall of the stove platform has a smoke inlet and is connected to a flue. The flue passes through the water storage tank and extends to the outside of the stove body.

The ignition control wire of the igniter is connected to the atomizing controller. Some igniters are also equipped with a power cord, which is directly connected to the power switch. The ignition control line of the atomizer is connected to the igniter, the electromagnetic pump line of the atomizer is connected to the oil pump, the input end of the oil pump is connected to the oil tank, the output end of the oil pump is equipped with an oil spray head and is placed in the oil spray hole of the furnace core, the fan line of the atomizer is connected to the blower, the air outlet of the blower is connected to the air inlet of the furnace core, and the power line of the atomizer is connected to the power switch. The output line of the temperature control display is connected to the solenoid valve, and the end of the probe line is a temperature sensor located at the outlet of the water storage tank. Its power line is connected to the power switch.

[0043] The inner wall of the furnace platform is inverted conical, and a ring-shaped mounting bracket is provided at the bottom. The furnace core is fixed to the center of the furnace platform through the mounting bracket.

[0044] The furnace core structure includes a cylindrical base with an oil spray hole and an ignition hole at the bottom. An air inlet is opened on the side wall of the base. A cylindrical cover box is placed inside the base. An oil spray channel is opened at the center of the top of the cover box. A cylindrical air box is snapped on top of the cover box.

The top of the air box is open and covered with a cover plate. The cover plate is star-shaped and has multiple vertical ventilation gaps distributed around it at intervals. A tubular placement seat is provided above the cover plate, and a horn-shaped reflector is above the placement seat.

[0045] The reflector disc blades are arranged in a ring with multiple ridges, each ridge has a hole, and there are protrusions between the ridges.

[0046] The inlet and outlet pipe joints are located diagonally opposite each other in the water storage tank. This increases the water flow path, ensuring that the cold water is fully heated as it circulates clockwise or counterclockwise.

[0047] The flue includes a heat exchange pipe installed inside the water storage tank and a flue outlet pipe outside the water storage tank.

[0048] The heat exchange tube is annular and is interrupted by a baffle in an arc-shaped section. The flue gas inlet is connected to one side of the baffle, and the flue gas outlet is connected to the other side of the baffle. This design increases the travel distance of the high-temperature gas generated during combustion, requiring it to circulate completely before leaving the heat exchange tube, thus improving heat exchange efficiency. The heat exchange tube can also be configured as a spiral shape.

[0049] The outer end of the water outlet pipe is connected to an insulated water tank, which uses a water pump to deliver hot water to the water-using equipment.

[0050] The control panels for the temperature display, atomization controller, and power switch are located on the front panel of the stove for easy operation.

[0051] The stove body is provided with a smoke and heat recovery system 19. The structure of the smoke and heat recovery system includes: a sealed water storage tank II 19-1 outside the smoke outlet pipe, a smoke exhaust fan 19-2 at the top of the water storage tank II, the smoke exhaust fan being connected to the end of the smoke outlet pipe, a water inlet II 19-4 at the bottom of the water storage tank II, a water outlet II 19-3 at the top, and the water outlet II being connected to the water inlet of the stove platform through a water inlet pipe.

[0052] The flue pipe is S-shaped inside the water storage tank. The S-shape increases the flue pipe path and enhances the heat exchange rate.

[0053] The water inlet pipe is equipped with a check valve 19-5 and a solenoid valve near the furnace inlet. The solenoid valve is connected to the temperature control display via a wire. The check valve (one-way valve) can effectively prevent the backflow of high-temperature water in the furnace.

[0054] Compared with Example 1, this example adds a smoke and heat recovery system at the rear of the stove.

[0055] The high-temperature gas in the flue gas pipe undergoes a heat exchange in the furnace, and the remaining secondary high-temperature gas undergoes a second heat exchange in the flue gas heat recovery system, fully transferring the heat energy to the water.

[0056] The principle is as follows: the flue gas heat recovery system can preheat the water entering the furnace. The cold water (tap water) first enters the water storage tank II, and after exchanging heat with the secondary high temperature gas in the flue gas pipe, it flows out from the water outlet at the top and enters the furnace through the water inlet pipe.

[0057] The technical benefits are: firstly, it makes full use of the waste heat in the flue pipe, improving the thermal energy utilization rate and benefiting the environment; secondly, the tap water is preheated before entering the furnace, improving the heating efficiency and enabling the water in the furnace to be heated to the preset temperature in a shorter time.

[0058] After autumn testing, if only the furnace platform is used for heat exchange, the gas temperature at the end of the flue is close to 100 degrees Celsius, while after adding the flue heat recovery system, the gas temperature at the end of the flue is close to 30 degrees Celsius.
