Description

Technical Field

[0001] The present invention relates to the field of range hoods, and particularly to a combined range hood with cleaning and pollution removal functions. Background Art

[0002] As one of the relatively common kitchen appliances at present, compared with traditional range hoods, the oil fumes of the combined range hood are all extracted towards the bottom, which results in a longer flue length for this type of combined range hood. This also causes a large amount of oil fumes to accumulate inside it. If the oil fumes in a traditional ordinary combined range hood accumulate to a certain amount, they will flow and accumulate. However, if there is a combined range hood with oil fume purification installed in the flue, such as electrostatic filtration, etc., it is very easy to have a certain degree of blockage, resulting in poor gas circulation. After being used for a certain period of time, the internal cleaning steps are complex, which is not conducive to household use. Summary of the Invention

[0003] The purpose of the present invention is to provide a combined range hood with cleaning and pollution removal functions in order to solve the problem of troublesome cleaning of the combined range hood.

[0004] In order to achieve the above purpose, the present invention adopts the following technical scheme: A combined range hood with cleaning and pollution removal functions includes a cooking range and a flue fixedly embedded thereon, and also includes smoke hoods symmetrically arranged on both sides of the flue. An electrostatic smoke remover is jointly arranged in the flue and the cooking range. A smoke exhaust unit communicated with the flue is installed in the cooking range. The smoke exhaust unit includes a negative pressure chamber and a centrifugal fan blade for air extraction therein. A smoke port assembly for controlling the on-off of the flue is installed at the top of the flue. The smoke port assembly includes a main door assembly and a driving assembly for driving the main door assembly to deflect, and also includes two side door assemblies installed in the smoke hood and in transmission cooperation with the driving assembly. A cleaning assembly for cleaning the flue, the electrostatic smoke remover and the smoke exhaust unit is also installed at the top of the flue. The cleaning assembly includes a liquid storage tank and a plurality of bubble blowing assemblies communicated therewith. The bubble blowing assembly includes an air extraction pipe and a bubble blowing head installed at the bottom end thereof. The bubble blowing head is installed with a siphon pipe communicated with the liquid storage tank. When the smoke exhaust unit is started, the smoke port assembly starts with a delay. A negative pressure is formed in the flue under the action of the smoke exhaust unit. External air passes through a plurality of cleaning assemblies to form dense bubbles. The bubbles move with the air flow and gradually break in the flue, forming a liquid film on the inner wall of the flue, the smoke exhaust unit and the electrostatic smoke remover locally. After the smoke port assembly is started, the oil fumes enter the flue. The liquid film reduces the adhesion between the oil stains and the metal surface. After the smoke port assembly is closed, the smoke exhaust unit is closed with a delay, and a negative pressure is formed in the flue. The dense bubbles clean the flue.

[0005] This technical solution drives the bubbles to actively adsorb the oil stains through the smoke exhaust negative pressure. The liquid film reduces the adhesion and reduces the residue; it avoids the blockage of the purification device; the centrifugal wind field and the foam cleaning act synergistically to maintain the suction and exhaust efficiency of the system for a long time, and significantly reduce the frequency of manual maintenance.

[0007] As a further description of the above technical solution: the flue includes a smoke pipe embedded and fixed with one side of the stove, and smoke return holes connected with two smoke hoods are symmetrically opened on both sides of the inner wall of the smoke pipe. The inner wall of the smoke pipe is fixed with a straight sealing plate that cooperates with the open state of the main door assembly to close, and the upper surface of the straight sealing plate and the inner wall of the smoke pipe are jointly fixed with an arc sealing plate.

[0008] As a further description of the above technical solution: the cleaning component also includes a one-way air nozzle arranged at the top of the liquid storage tank, the surface of the liquid storage tank is provided with a plurality of serial ports for the bubble blowing component to pass through, the liquid storage tank is fixedly connected to the upper surface of the straight sealing plate, and the upper surface of the liquid storage tank is provided with a threaded cover.

[0009] As a further description of the above technical solution: an anti-blocking head is fixed to the top of the exhaust pipe, and a plurality of openings communicating with the top of the exhaust pipe are opened on the side of the anti-blocking head.

[0010] As a further description of the above technical solution: the bubble blowing head includes a cavitation ring fixedly connected to the bottom end of the exhaust pipe, a fitting groove is opened on one side of the cavitation ring, the inner wall of the fitting groove is connected to one end of the siphon tube, a liquid uniformizing rod is fitted and slidable in the fitting groove, the liquid uniformizing rod is fixed with a fan blade, and the fan blade is rotatably installed on the inner wall of the exhaust pipe.

[0011] As a further description of the above technical solution: the driving assembly includes a driver fixed to one side of the smoke pipe, the output shaft of the driver is fixed with a swing arm, one end of the swing arm is movably connected with a transmission plate, the bottom end of the transmission plate is movably connected with a first deflection arm, and the inner wall of the first deflection arm is fixed with a deflection shaft for the movement of the main door assembly; A second deflection arm is fixed to the end of the deflection shaft, a sliding pin is fixed to the end of the second deflection arm, and the driving assembly also includes a partition fixed to the inner wall of the smoke hood, and the transmission plate penetrates and slides on the surface of the partition.

[0012] As a further description of the above technical solution: The side door assembly includes a carriage, the surface of the carriage is provided with sliding holes for the cooperative limit sliding of sliding pins, the two ends of the carriage are limited and slid with guide rails, the guide rails are fixed on the inner wall of the smoke hood, one side of the carriage is fixed with an elastic telescopic rod, and one end of the elastic telescopic rod is movably connected with a second door panel through a pin shaft, and the second door panel is hinged on the inner wall of the smoke hood.

[0013] As a further description of the above technical solution: The main door assembly includes a first door panel for blocking one side of the smoke pipe, two holding plates fixed to one side of the first door panel and fixed to a deflection shaft, and a plurality of guide plates are commonly fixed to the opposite surfaces of the two holding plates.

[0014] As a further description of the above technical solution: The electrostatic smoke eliminator includes a positive charge grid and an adsorption grid arranged in the smoke pipe, and also includes an electrostatic generator installed in the stove top.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This technical solution drives the bubbles to actively adsorb oil stains through the exhaust negative pressure, and the liquid film reduces adhesion and reduces residues; it avoids the blockage of the purification device; the centrifugal wind field and foam cleaning act synergistically to maintain the suction and exhaust efficiency of the system for a long time, which is beneficial to reducing the frequency of manual maintenance.

[0016] When this solution is in use, the cleaning agent is filled into the liquid storage bin. During use, first start the motor of the exhaust unit, and after its centrifugal fan blade starts, the gas in the smoke pipe is pumped out. At this time, the first door panel is not opened and keeps one side of the top of the smoke pipe closed, making the inside of the smoke pipe present negative pressure. The outside gas enters through the air extraction pipe. The high-speed air flow passes through the bubble blowing head at the bottom end of the air extraction pipe. The high-speed air flow forms a low pressure at the bottom end of the siphon pipe. Cooperating with the suction force in the smoke pipe, the siphon pipe pumps out the cleaning agent in the liquid storage bin and transports it to the air bubble ring of the bubble blowing head. The liquid homogenizing rod evenly distributes the cleaning agent to form bubbles and fly out. The bubbles flow with the air flow and pass through the positive charge grid and the adsorption grid and then enter the exhaust unit, making the bubbles gradually burst and splash the cleaning agent to adhere to the metal surface to form a liquid film. Then, when the main door assembly is opened and the oil fume enters, it can be used. This method can form a thin film in the flue. After contacting the oil fume, the oil fume solidifies on the surface of the thin film, which can greatly reduce the adhesion strength of the oil liquid and improve its free dropping speed, and there will be no adhesion and gelatinization of the oil fume; After use, first close the main door assembly and the two second door panels to create a negative pressure in the flue. The cleaner forms dense bubbles in cooperation with the bubble blowing assembly, floats with the airflow, and provides a cleaning agent to the inner wall of the flue, the surface of the positive charge grid, and the adsorption grid during the bursting process. The oil liquid with reduced adhesion strength is washed downward as the cleaning agent flows downward. Then, the exhaust fan unit can be shut down and wait for the oil liquid to flow downward and converge into the sewage collection tray during the static process. This method can quickly clean the oil liquid, achieve internal self-cleaning, and avoid blockage of the smoke pipe caused by oil liquid adhesion.

[0017] This solution also improves the smoke inlet method. The first door panel at the top is opened to collect cooking fumes, and at the same time, a small amount of laterally scattered cooking fumes can be captured by the two smoke hoods through the second door panels and enter the smoke pipe through the smoke return holes. This method can ensure the full suction of cooking fumes and avoid lateral escape. Compared with the current method of continuously increasing the suction force to avoid escape, it provides a new way to remove cooking fumes and has a better effect of removing cooking fumes.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 creative efforts shall fall within the protection scope of the present invention.

[0031] As Figure 1 - Figure 11 shown, the present invention provides: a net pollution integrated cooktop, including a cooktop 10 and a flue 20 fixedly embedded thereon, and further including smoke hoods 30 symmetrically arranged on both sides of the flue 20. An electrostatic smoke remover 60 is jointly arranged in the flue 20 and the cooktop 10. A smoke exhaust unit 70 communicated with the flue 20 is installed in the cooktop 10. The smoke exhaust unit 70 includes a negative pressure chamber 71 and a centrifugal fan blade 72 for air extraction therein. A smoke outlet assembly 40 for controlling the on / off of the flue 20 is installed at the top of the flue 20. The smoke outlet assembly 40 includes a main door assembly 43 and a driving assembly 41 for driving the main door assembly 43 to deflect, and further includes two side door assemblies 42 installed in the smoke hood 30 and in transmission cooperation with the driving assembly 41.

[0032] A cleaning assembly 50 for cleaning the flue 20, the electrostatic smoke eliminator 60 and the smoke exhaust unit 70 is also installed on the top of the flue 20. The cleaning assembly 50 includes a liquid storage tank 52 and a plurality of bubble blowing assemblies 51 connected thereto. The bubble blowing assembly 51 includes an exhaust pipe 511 and a bubble blowing head 512 installed at its bottom end. The bubble blowing head 512 is equipped with a siphon tube 513 connected to the liquid storage tank 52.

[0033] When the smoke exhaust unit 70 is started, the smoke outlet component 40 is started with a delay, and the flue 20 forms a negative pressure under the action of the smoke exhaust unit 70. The outside air passes through a number of cleaning components 50 to form dense bubbles. The bubbles move with the airflow, and gradually burst in the flue 20 to form a liquid film on the inner wall of the flue 20, the smoke exhaust unit 70 and the electrostatic smoke precipitator 60. After the smoke outlet component 40 is started, the oil smoke enters the flue 20, and the liquid film reduces the adhesion between the oil stains and the metal surface. After the smoke outlet component 40 is closed, the smoke exhaust unit 70 is closed with a delay, and a negative pressure is formed in the flue 20, and the dense bubbles clean the flue 20.

[0034] Specifically, Figure 6 As shown: the smoke exhaust unit 70 also includes a motor 74, the output shaft of the motor 74 and the input shaft of the centrifugal fan blade 72 are jointly provided with a pulley group 73, one side of the negative pressure chamber 71 is connected to the flue 20, the lower surface of the negative pressure chamber 71 is connected to the air outlet chamber 75, the lower surface of the air outlet chamber 75 is sealed with a dirt receiving tray 77, the lower surface of the air outlet chamber 75 is provided with an oil discharge port 76 connected to the dirt receiving tray 77, the dirt receiving tray 77 is arranged at the bottom of the flue 20, and the air inlet position of the negative pressure chamber 71 is inclined and provided with a baffle 78.

[0035] By setting up the pulley group 73, the motor 74 can rotate with multiple centrifugal blades 72 through the pulley group 73, wherein the centrifugal blades 72 guide the air flow in the negative pressure chamber 71 when rotating, wherein the air flow enters the air outlet chamber 75 and is discharged through one side of the air outlet chamber 75, and the oil flows through the oil drain port 76 and enters the dirt collecting tray 77.

[0036] The baffle plate 78 is arranged in an inclined shape so as to be located at the air inlet of the negative pressure chamber 71 for protection. The oil flowing downward in the smoke pipe 21 can drip under the guidance of the baffle plate 78 and avoid entering the negative pressure chamber 71 .

[0037] Specifically, Figure 4 and Figure 7 As shown: the flue 20 includes a smoke pipe 21 which is embedded and fixed on one side of the stove top 10, and smoke return holes 24 connected to two smoke hoods 30 are symmetrically opened on both sides of the inner wall of the smoke pipe 21. A straight sealing plate 22 that cooperates with the open state of the main door assembly 43 is fixed to the inner wall of the smoke pipe 21, and an arc sealing plate 23 is fixed to the upper surface of the straight sealing plate 22 and the inner wall of the smoke pipe 21.

[0038] By setting up the smoke pipe 21, the smoke pipe 21 can guide the airflow over a relatively long distance. Through the return smoke holes 24 on both sides, a negative pressure can be formed inside the smoke hood 30 to cooperate with the suction of the smoke.

[0039] By setting up the straight sealing plate 22, as Figure 7 and Figure 11 shown, when the holding plate 432 of the main door assembly 43 rotates along the deflection shaft 415, its first door panel 431 deflects accordingly. After the first door panel 431 deflects, it can fit against one side of the straight sealing plate 22 to maintain the seal. At this time, the negative pressure inside the flue 20 will not affect the cleaning assembly 50.

[0040] By setting up the arc sealing plate 23, which mainly plays a partitioning role and can partition along the movement track of the first door panel 431. The bubble blowing head 512 of the cleaning assembly 50 is fixedly penetrated on the surface of the arc sealing plate 23 to maintain the partition and support it at the same time, and form dense bubbles that can first contact the main door assembly 43 to clean the oil adhered to it.

[0041] Specifically, as Figure 7 shown: The cleaning assembly 50 further includes a one-way air nozzle 53 arranged at the top of the liquid storage bin 52. A number of serial ports 54 for the bubble blowing assembly 51 to penetrate are opened on the surface of the liquid storage bin 52. The liquid storage bin 52 is fixedly connected to the upper surface of the straight sealing plate 22, and a threaded cover is arranged on the upper surface of the liquid storage bin 52.

[0042] By setting up the one-way air nozzle 53, when a negative pressure is formed in the smoke pipe 21, based on the cooperation of the siphon effect or the negative pressure attraction effect, the cleaning agent in the liquid storage bin 52 can be sucked out through the siphon pipe 513, and the outside air can enter the liquid storage bin 52 through the one-way air nozzle 53 to ensure the stable supply of the cleaning agent, and the supply speed is proportional to the air extraction efficiency of the smoke exhaust unit 70.

[0043] Specifically, as Figure 8 shown: A anti-blocking head 514 is fixed at the top end of the air extraction pipe 511, and a number of openings communicating with the top end of the air extraction pipe 511 are laterally opened on the anti-blocking head 514.

[0044] By setting up the anti-blocking head 514, which is located at the top end of the air extraction pipe 511 and fits against the top of the flue 20. The multiple lateral openings can allow the airflow to enter the air extraction pipe 511. Even if some of the openings are blocked, the air intake can still be maintained. This method can largely avoid being blocked and avoid being blocked by placed objects.

[0045] Specifically, as Figure 8As shown: The bubble blowing head 512 includes an air bubble ring 5123 fixedly connected to the bottom end of the air extraction pipe 511. A fitting groove 5124 is formed on one side of the air bubble ring 5123. The inner wall of the fitting groove 5124 is communicated with one end of the siphon pipe 513. A liquid homogenizing rod 5122 is slidably fitted in the fitting groove 5124. The liquid homogenizing rod 5122 is fixedly provided with a wind blade 5121, and the wind blade 5121 is rotatably installed on the inner wall of the air extraction pipe 511.

[0046] By providing the fitting groove 5124, when the siphon pipe 513 transfers the cleaner into the fitting groove 5124, the wind blade 5121 rotates under the action of the high-speed air flow, and drives the liquid homogenizing rod 5122 to rotate in the fitting groove 5124 and quickly and evenly disperse the cleaner on the air bubble ring 5123, so as to form a liquid film, and form dense foam composed of the cleaner under the action of the air flow. Moreover, the dispersed bubbles are dispersed and moved along with the air flow, and can splash when broken, so as to keep uniform dispersion in the complex flue 20.

[0047] Specifically, as Figure 9 shown: The driving assembly 41 includes a driver 411 fixed on one side of the smoke pipe 21. An output shaft of the driver 411 is fixedly provided with a swing arm 412. One end of the swing arm 412 is movably connected with a transmission plate 413. The bottom end of the transmission plate 413 is movably connected with a first deflection arm 414. A deflection shaft 415 for the movement of the main door assembly 43 is fixedly installed on the inner wall of the first deflection arm 414.

[0048] The driver 411 drives the swing arm 412 to rotate. The arm length of the swing arm 412 is the movement radius, and the diameter of its circular track is the moving distance at the top end of the transmission plate 413. And this moving distance can drive the first deflection arm 414 to rotate by ninety degrees through the transmission plate 413.

[0049] A second deflection arm 416 is fixedly installed at the end of the deflection shaft 415. A sliding pin 417 is fixedly installed at the end of the second deflection arm 416. The driving assembly 41 further includes a partition plate 418 fixed on the inner wall of the smoke hood 30. The transmission plate 413 penetrates and slides on the surface of the partition plate 418.

[0050] Specifically, as Figure 9 shown: The side door assembly 42 includes a sliding frame 421. A sliding hole 422 for limiting the sliding of the sliding pin 417 is formed on the surface of the sliding frame 421. Guide rails 423 are slidably limited at both ends of the sliding frame 421. The guide rails 423 are fixed on the inner wall of the smoke hood 30. An elastic telescopic rod 424 is fixedly installed on one side of the sliding frame 421. One end of the elastic telescopic rod 424 is movably connected with a second door plate 425 through a pin shaft. The second door plate 425 is hinged on the inner wall of the smoke hood 30.

[0051] The sliding pin 417 of the second deflection arm 416 can cooperate with and slide within the sliding hole 422. The sliding hole 422 can eliminate the vertical movement of the second deflection arm 416, only retaining the horizontal displacement force of the second deflection arm 416, maintaining the control of the elastic telescopic rod 424, and when the elastic telescopic rod 424 is stretched, maintaining an elastic pulling force for closing the second door panel 425. When opening, through the compression of the elastic telescopic rod 424, the second door panel 425 is pushed open by the elastic force. When needed, the second door panel 425 can be directly pulled to open for internal cleaning during closing. The cleaning agent is more convenient at this position, and there is less lateral oil fume and slower accumulation of oil stains. And it does not adopt the method of using a cleaning agent for cleaning.

[0052] Specifically, as Figure 7 shown: The main door assembly 43 includes a first door panel 431 that seals one side of the smoke pipe 21. On one side of the first door panel 431, two retaining plates 432 fixed to the deflection shaft 415 are fixed, and a plurality of guide plates 433 are commonly fixed to the opposite surfaces of the two retaining plates 432.

[0053] By providing the guide plates 433, the guide plates 433 are located on one side of the first door panel 431 and can contact the initially entering oil fume, enabling a large amount of oil liquid to adhere to them, reducing the oil liquid in the flue 20. At the same time, this position is the first to contact the cleaning agent and has a better cleaning effect.

[0054] Specifically, as Figure 3 and Figure 4 shown: The electrostatic smoke remover 60 includes a positive charge grid 62 and an adsorption grid 63 arranged in the smoke pipe 21, and also includes an electrostatic generator 61 installed in the cooking range 10.

[0055] The electrostatic generator 61 can generate a high-voltage DC power supply, enabling the positive charge grid 62 and the adsorption grid 63 to form positive and negative electrodes respectively, and using a strong electric field to ionize the oil fume particles and adsorb the charged pollutants to play a cleaning role.

[0056] In this solution, the cleaning agent includes two types of cleaning agents, lipophilic and lipophobic, which are mixed with water and then added to the liquid storage tank 52. If a lipophobic cleaning agent is used, it adheres to the inner wall of the flue 20 to prevent the adhesion of oil fume, and the oil fume can quickly slide off. If a lipophilic cleaning agent is used, it contains hydrophilic groups and lipophilic groups, can adsorb on the surface of the oil stain, reduce the surface tension between the oil stain and water, and at the same time, through the emulsification effect, the oil liquid can emulsify the oil stain into tiny oil droplets. These tiny oil droplets are dispersed and suspended in water to form an emulsion, thereby preventing the oil droplets from re-accumulating. Further, during normal use, a lipophobic cleaning agent is adopted, and after a period of time, a lipophilic cleaning agent is switched to clean the interior, and they are used alternately.

[0057] Example 1: When in use, the cleaning agent is filled into the liquid storage tank 52, and the motor 74 of the smoke exhaust unit 70 is started first, so that the motor 74 drives the centrifugal fan blades 72 to rotate through the pulley group 73, and the gas in the smoke pipe 21 is extracted. At this time, the first door panel 431 is not opened, and one side of the top of the smoke pipe 21 is closed, so that the smoke pipe 21 is under negative pressure, and the external gas enters through the exhaust pipe 511, and the high-speed airflow passes through the bubble blowing head 512 at the bottom of the exhaust pipe 511. The high-speed airflow forms a low pressure at the bottom of the siphon tube 513, and cooperates with the suction force in the smoke pipe 21, so that the siphon tube 513 extracts the liquid The detergent in the bin 52 is extracted and transferred to the cavitation ring 5123 of the bubble blowing head 512, and the fan blade 5121 rotates in the exhaust pipe 511 with the action of the airflow, and slides with the liquid leveling rod 5122 in the fitting groove 5124 to evenly distribute the detergent. After the detergent is evenly distributed, bubbles are formed under the action of the airflow and fly out. The bubbles flow with the airflow and pass through the positive charge grid 62 and the adsorption grid 63 and then enter the smoke exhaust unit 70. When the bubbles move with the airflow, some of the detergent bubbles gradually burst and splash around, gradually forming a layer of liquid film on the metal surface.

[0058] Then the driver 411 is started, and the driver 411 drives the swing arm 412 to rotate. After the swing arm 412 rotates, it moves the top end of the transmission plate 413. When the top end of the transmission plate 413 moves, its bottom end rotates with the first deflection arm 414. The first deflection arm 414 rotates synchronously with the main door assembly 43 and the second deflection arm 416 through the deflection shaft 415. The main door assembly 43 is in a gradually opening state at this time. At the same time, the sliding pin 417 at the end of the second deflection arm 416 slides in the sliding hole 422 and moves the slide 421 horizontally on the two guide rails 423. When the slide 421 moves horizontally, the elastic telescopic rod 424 in a stretched state gradually resets and pushes open the second door panel 425. After the second door panel 425 is opened, the elastic telescopic rod 424 is gradually compressed to maintain pressure.

[0059] After the main door assembly 43 and the second door panel 425 are opened synchronously, the oil smoke enters the smoke pipe 21 under the negative pressure suction. This method can form a thin film in the flue 20. After contacting the oil smoke, the oil smoke solidifies on the surface of the film, reducing the adhesion strength of the oil in the flue 20.

[0060] After use, the driver 411 is reversed, the main door assembly 43 and the two second door panels 425 are gradually closed, a negative pressure is formed in the flue 20, and the cleaner forms dense bubbles in cooperation with the bubble blowing assembly 51, which float with the airflow and provide cleaning agent to the inner wall of the flue 20, the positive charge grid 62 and the adsorption grid 63 surface during the explosion, and the oil with reduced adhesion strength is flushed downward during the downward flow of the cleaning agent, and the smoke exhaust unit 70 can be shut down and wait for it to flow downward and converge into the dirt receiving tray 77 during the static process. This method can quickly clean the oil and realize internal self-cleaning, avoiding the blockage of the smoke pipe 21 caused by the adhesion of oil.

[0061] The above method can combine with the flue gas to enter into the flue pipe 21. In the high-voltage electrostatic field formed by passing through the positive charge grid 62, the oil fume particles are ionized, that is, they obtain charges and become charged particles. The oil fume of the charged particles is adsorbed under the action of the electric field force of the adsorption grid 63. Among them, under the action of the oil-repellent cleaner on the surface of the adsorption grid 63, the oil liquid keeps dripping rapidly, ensuring its good adsorption effect.

[0062] Embodiment 2: It is basically the same as Embodiment 1, except that the driver 411 controls the deflection angle of the main door assembly 43 to be less than ninety degrees. More specifically, the bubble blowing head 512 is located inside the first door panel 431 of the main door assembly 43, so that it generates dense bubbles while sucking in the flue gas, forming a mixture of flue gas and bubbles.

[0063] When the bubbles burst, they are better mixed with the flue gas, and have a better treatment effect on the relatively thick flue gas. Based on the relatively small opening of the first door panel 431, its suction range is reduced, but the air flow rate is faster.

[0064] Embodiment 3: It is basically the same as Embodiment 1 or Embodiment 2, except that one liquid storage tank 52 is changed to two liquid storage tanks 52, which store two kinds of cleaners, namely oil-loving and oil-repellent, respectively. The odd-numbered and even-numbered bubble blowing assemblies 51 are respectively connected to the two liquid storage tanks 52, and the odd-numbered bubble blowing assemblies 51 and the even-numbered bubble blowing assemblies 51 are respectively connected in series, and their ends are commonly connected with a switching valve for air intake.

[0065] When in use, at the beginning of startup, the odd-numbered bubble blowing assemblies 51 are connected to the liquid storage tank 52 of the oil-repellent cleaner, and the odd-numbered bubble blowing assemblies 51 are connected through the switching valve, so that an oil-repellent liquid film is formed in the flue 20. When it is closed, the even-numbered bubble blowing assemblies 51 are connected to the liquid storage tank 52 of the oil-loving cleaner, and at the same time the switching valve remains connected, and the odd-numbered bubble blowing assemblies 51 are closed, so as to clean the interior. This method can achieve a more thorough cleaning effect on the interior.

[0066] Based on the above three embodiments, the present solution also improves the smoke inlet method. The first door panel 431 at the top is opened to collect the oil fume. At the same time, the two smoke hoods 30 are opened on both sides of the first door panel 431 through the second door panel 425. A small amount of laterally scattered oil fume can be captured by the smoke hoods 30 and enter the flue pipe 21 through the smoke return holes 24, so that the oil fume can be fully sucked, avoiding lateral escape. Compared with the current method of continuously increasing the suction force to avoid escape, a new oil fume removal method is provided, which has a better oil fume removal effect.

[0067] After generating bubbles with the cleaner and mixing them with the flue gas, a cleaning film is formed during the bursting of the bubbles, which not only improves the adhesion reduction effect of the oil fume inside the flue 20, but also combines the electric field effects of the positive charge grid 62 and the adsorption grid 63 to achieve efficient adsorption and rapid dripping of the oil fume particles. This design significantly reduces the accumulation of oil fume in the flue 20, improves the cleaning efficiency, and at the same time avoids the problem of blockage of the flue 20 caused by the adhesion of oil liquid in the traditional method. In addition, the synchronous opening and closing design of the double door panels, through the coordinated action of the first door panel 431 at the top and the second door panels 425 on both sides, can effectively collect the oil fume in multiple directions, avoid lateral escape, and improve the oil fume collection efficiency.

[0068] Meanwhile, if the layout scheme of Embodiment 3 is adopted, the distribution of the liquid storage tank 52 can be controlled by the switching valve, enabling cleaners with different properties to act successively, forming the combined effect of lipophilic and lipophobic cleaning, effectively removing the oil fume residue while enhancing the cleaning effect. This dual-chamber mode of the liquid storage tank 52 significantly improves the cleaning flexibility and the cleaning effect of the inner wall of the flue 20.

[0069] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
