Description

Technical Field

[0001] The utility model relates to the field of frying stove devices and equipment, in particular to a silent and energy-saving frying stove used for liquid fuel. Background Art

[0002] Existing cooking stoves are mainly divided into gas stoves that use liquefied natural gas as fuel and oil stoves that use liquid fuel as fuel. In the vast commercial cooking stove market, most of them use liquefied gas fuel, such as gas cylinders, which are widely used in schools, troops, restaurants, hotels and other multi-person cooking occasions. However, this traditional liquefied gas has problems such as low calorific value, high cost, low flash point, flammability and explosion, and great safety hazards. Due to the great safety hazards of liquefied gas fuel, commercial stove fuels have begun to turn to safe fuels with relatively high flash points-liquid fuels. Among them, civilian clean liquid fuel is a non-toxic and harmless high-flash point liquid alkane kitchen stove clean fuel made of synthetic hydrocarbons, high-flash point hydrocarbon compounds and other straight-chain alkanes and branched alkanes as raw materials and composite additives. The main advantages of this fuel oil are wide application, low price, high calorific value, good safety and clean and environmentally friendly.

[0003] The existing liquid fuel oil stove mainly adopts electric fuel injection stove, which is mainly used in commercial fierce fire stoves, a series of Chinese food frying stoves, large pot stoves, and other kitchen stoves such as steamers, stew barrels, cooking stoves, clay pot stoves, etc. and heaters. Its disadvantages are: the existing electric fuel injection stove belongs to an open combustion system, and the liquid fuel needs to be added to 12 kg of pressure and atomized into gas before it can be burned. If the pressure is lower than 2 kg, atomization cannot be achieved. Therefore, it can only be burned and heated in medium and high fire mode, and it is impossible to open a small fire for slow heating. In addition, the wind pressure is very large, the noise is also very loud, and the heat utilization rate is also low. Therefore, it is often seen that many commercial stoves have fierce flames when in use, and a large amount of flames are ejected from the side of the pot, accompanied by a lot of noise.

[0004] Therefore, our company developed the first generation of liquid fuel stoves, see CN202410224133.0, a multi-stage silent energy-saving combustion device for liquid fuel. This device essentially changes the atomization combustion mode of the original electric fuel injection stove through the structural design of the ion combustion body, and changes the original open combustion mode of the electric fuel injection stove into a closed multi-stage combustion mode. It does not need to be atomized by a high-pressure atomizing nozzle, but only uses the temperature generated by the primary combustion of the first-level combustion chamber in the ion combustion body, combined with the air intake of the cyclone air intake cylinder, to achieve true high-temperature vaporization of the liquid fuel and precise mixing of air and fuel. Its combustion method is no longer to directly heat the pot through flames, but to heat the fuel through thermal radiation after full combustion. Compared with direct flame heating, the heating effect is better, the heat utilization rate is greatly improved, and the heat energy loss is greatly reduced. Compared with the electric fuel injection stove, the heat utilization rate is nearly doubled, and the energy consumption such as oil and electricity is only half of the original, and it is safer, more independent and more applicable. In addition, when performing slow combustion in low-fire mode, the liquid fuel can stably fission and burn on the ion spark divider teeth in the secondary combustion chamber, continuously generating stable heat.

[0005] However, the following problems still need to be solved when the device is used in a frying stove:

[0006] 1. Regardless of the first generation of liquid fuel stoves developed by our company or the existing electric spray stoves, liquid fuel is injected by pressure and blown into the air by a fan to assist combustion. The stove bodies are open and cannot be equipped with silencers. Therefore, when used on stoves such as household stoves and commercial stoves, the noise generated by liquid fuel energy supply is an unavoidable disadvantage. The first generation of liquid fuel stoves developed by our company has greatly reduced oil supply pressure and air volume, and its noise decibels are greatly reduced, but there is still a certain amount of noise. If the noise problem can be solved, it will greatly promote the application and promotion of liquid fuel stoves.

[0007] 2. The application of the device on a frying stove requires the overall structure of the existing frying stove to be redesigned. Utility Model Content

[0030] The utility model will be further described below, specifically as follows:

[0031] A silent and energy-saving cooking stove for liquid fuel, see Figures 1 to 3, including a stove body 11, the top of the stove body 11 is provided with a table with a turret 12, a stove basin 10 is placed on the mouth of the turret 12 of the table, a liquid fuel combustion device is provided at the bottom of the stove basin 10, and the liquid fuel combustion device is composed of an ion combustion body 2 and a silencer combustion tube 1, the ion combustion body 2 is fixed to the bottom of the stove basin 10, the silencer combustion tube 1 passes through the stove basin 10 and is arranged in the stove basin 10, and the silencer combustion tube 1 is fixed on the fire outlet of the ion combustion body 2. The utility model arranges the liquid fuel combustion device at the bottom of the stove basin 10, the liquid fuel is first vaporized and burned through the ion combustion body 2, and then oxygen-enriched and fully fueled in the silencer combustion tube 1, and finally, the heat energy generated by the combustion is sprayed into the stove basin 10 through the silencer combustion tube 1 to heat the pots on the stove basin 10.

[0032] The utility model has a silencer combustion tube 1 of a larger diameter structure at the top and smaller diameter structure at the bottom. The large diameter tube opening at the top can increase the heating port area so that the heat energy generated by the combustion of the liquid fuel can fully heat the bottom of the cookware. The smaller diameter tube opening at the bottom of the silencer combustion tube 1 is convenient for docking with the fire outlet of the ion combustion body 2, and the small diameter tube structure can easily pass through the stove basin 10 with a smaller bottom area for some stove basins 10 with a smaller bottom surface.

[0033] Since the ion combustion body 2 adopts a spiral air intake method, the liquid fuel is gasified by the cyclone-assisted cyclone, and the flame ejected from the ion combustion body 2 is also cyclone-shaped. The cyclone-shaped flame will enter the ceramic silencer tube 7 with the cyclone spiral, and form a secondary combustion chamber at the lower part of the silencer combustion tube 1, and a tertiary combustion chamber at the upper part. The utility model designs a ceramic silencer tube 7 in the silencer combustion tube 1. The ceramic silencer tube 7 is a tubular structure, and the outer diameter is the same as the inner diameter of the silencer combustion tube 1. The ceramic silencer tube 7 can be made of porous mullite ceramics. Porous mullite ceramics have the characteristics of high porosity, low density, burning and high temperature resistance, and high mechanical strength. Its porous air-permeable structure has a good sound-absorbing and noise-reducing effect.

[0034] A plurality of silencer teeth are provided on the inner wall of the tube hole of the ceramic silencer tube 7. The structural design of the silencer teeth forms a wavy undulating structure in the tube hole. When the liquid fuel is vaporized and burned in the primary combustion chamber, the burning flame is blown up in a spiral from above the ion combustion body 2. A portion of the rotating flame enters the pores in the ceramic silencer tube 7 for silencing and noise reduction, and a portion of the rotating flame enters the undulating silencer teeth in the tube hole of the ceramic silencer tube 7 for further silencing and noise reduction, and burns and generates heat. The generated heat is ejected upward along the ceramic silencer tube 7. The design of the silencer teeth can also play a role in guiding wind in the vertical direction. The spiral flame will be silenced and decelerated in the ceramic silencer tube 7, and finally completely burned and converted into heat energy, and ejected from the top of the silencer combustion tube 1 in the vertical direction, which can play a role in guiding wind in the vertical direction. Through the design of the ceramic silencer tube 7, the noise problem of the liquid fuel stove is completely solved. When a low fire is turned on, basically no sound can be heard. When a high fire is turned on, the noise is similar to that of a natural gas stove.

[0035] Compared with the first generation of products, after the ceramic silencer 7 is installed, the spiral flame enters the lower part of the ceramic silencer 7, and a vortex hot air field is formed at the lower part. The high-temperature infrared field in the hot air field plays a heat-gathering role, so that the fuel can be burned quickly, and the heat utilization rate is improved. The CO, combustible gas and oil vapor coming out of the ion combustion body 2 will be completely burned in the hot air field, realizing secondary combustion. The temperature of the secondary combustion chamber reaches about 800°C. The heat generated by the combustion forms a second heat field in the tertiary combustion chamber, and the temperature can reach about 1300°C, which can reheat the fuel for combustion, and release the heat energy outward. Due to the complete combustion, almost no open flame can be seen at the fire outlet on the top of the silencer combustion tube 1. At this time, the flame of the liquid fuel combustion is basically completely converted into heat energy, and the pot is heated by heat radiation. Compared with the first generation of products, the addition of the ceramic silencer 7 can further improve the heat utilization rate, resulting in a further reduction in the required fuel consumption.

[0036] The turret 12 of the table is tilted. The tilted muzzle structure design makes the pot mouth slightly tilted towards the chef after the pot is placed, which is convenient for the chef to stir-fry. A lining basin 13 is mounted on the turret 12 of the table. The bottom of the lining basin 13 is provided with a through hole matching the bottom of the stove plate. The upper end of the stove basin 10 is mounted on the upper edge of the lining basin 13. The bottom of the stove basin 10 passes through the through hole and is located outside the lining basin 13. The lining basin 13 plays a role in limiting the installation of the stove basin 10. The upper edge of the lining basin 13 is used to overlap the edge of the stove basin 10. The through hole at the bottom can limit the bottom of the stove basin 10 to prevent the stove basin 10 from turning over with the stir-frying of the pot. The periphery of the table is buckled and fixed with the periphery of the stove body 11, and can be disassembled and stored when not in use.

[0037] A plurality of silencer teeth are provided on the inner wall of the tube hole of the ceramic silencer tube 7. The silencer teeth are arranged along the length direction of the ceramic silencer tube 7 and are evenly spaced along the circumferential direction of the tube hole, so that the silencer teeth form an undulating wave shape in the circumferential direction, which is more conducive to the silencer and noise reduction of the spiral flame. The heat after the silencer and noise reduction is discharged upward along the vertical direction of the silencer teeth. The tube hole at the upper part of the ceramic silencer tube 7 is a gradually expanding shape with a narrow bottom and a wide top, which can facilitate the heat energy to be dispersed upward, which is conducive to heating the bottom of the pot. A fire dividing plate 6 is provided on the top of the silencer combustion tube 1, and the fire dividing plate 6 can evenly disperse the heat ejected from the top of the silencer combustion tube 1.

[0038] An electrical installation board is provided at the bottom of the ion combustion body 2 for installing electrical equipment so that it is integrated at the bottom of the stove basin 10. A control box 14, a switching power supply 15, a fan 5 and an oil pump 4 are provided on the electrical installation board. A control panel 16 is provided on the front of the stove body 11. The control box 14 is electrically connected to the fan 5, the oil pump 4 and the control panel 16 respectively. The fan 5 is connected to the inside of the ion combustion body 2 to provide it with combustion-supporting air. The oil pump 4 is connected to the inside of the ion combustion body 2 through an oil supply pipe to pump liquid fuel into the ion combustion body 2 for vaporization and combustion. The switching power supply 15 supplies power to the control box 14, the fan 5 and the oil pump 4. The user outputs a switching instruction through the control panel 16 and controls the switch of the fan 5 and the oil pump 4 through the control box 14.

[0039] It also includes a thermocouple probe, which is arranged at the lower part of the ceramic silencer 7 and is electrically connected to the control box 14. The flame combustion state can be detected by the thermocouple probe to determine whether the liquid fuel is burning so as to perform flameout protection.

[0040] As a preferred solution, the ion combustion body 2 adopts the ion combustion body 2 of the second generation product developed by the company, see CN202410633760X a multi-stage silent energy-saving combustion device for liquid fuel, such as Figure 4The device essentially changes the atomization combustion mode of the original electric fuel injection stove through the structural design of the ion combustion body, and changes the original open combustion mode of the electric fuel injection stove into a closed multi-stage combustion mode. It does not need to be atomized by a high-pressure atomizing nozzle, but only uses the temperature generated by the primary combustion of the first-stage combustion chamber in the ion combustion body 2, combined with the air intake of the cyclone intake cylinder, to achieve true high-temperature vaporization of liquid fuel and precise mixing of air and fuel ratio. Through the designed ceramic silencer tube 7, a vortex hot air field is formed at the lower part of the ceramic silencer tube 7 as a secondary combustion chamber, and a hot air field is formed at the upper part of the ceramic silencer tube 7 as a tertiary combustion chamber. When the liquid fuel is vaporized and burned in the primary combustion chamber, the burning flame spirally rises from above the ion combustion body, enters the secondary combustion chamber for full combustion, and releases heat in the tertiary combustion chamber, which is converted into thermal energy and ejected from the top of the silencer combustion tube to heat the cookware. The thermal utilization rate of the entire combustion device is improved, and the fuel consumption is further reduced. The problem of silencing and noise reduction of liquid fuel stoves for many years has been solved. The combustion method is no longer to directly heat the cookware through flames, but to heat the fuel through thermal radiation after full combustion. Compared with direct flame heating, the heating effect is better, the thermal utilization rate is greatly improved, and the thermal energy loss is greatly reduced. Compared with the electric fuel injection stove, the thermal utilization rate is increased by nearly one-fold, and the energy consumption such as oil and electricity is only half of the original, and it is safer, more independent, and more applicable. Moreover, the overall height of the combustion device is reduced, and the restrictions on the size of the stove basin and the height of the stove body are reduced, which is more conducive to the installation design of small stoves such as household stoves.
