Description

Technical Field

[0001] This invention relates to the field of smoking oven technology, and more particularly to a self-cleaning smoking oven device. Background Technology

[0002] With the rapid development of the urban food processing industry, smoking technology has been widely used in the processing of meat, bean products, and other products due to its unique flavor and preservative effect. However, traditional smokehouses produce a large amount of residual smoke containing oil fumes, particulate matter, and volatile organic compounds (VOCs) during operation. While the smoke inside the smokehouse can circulate during use, the residual smoke needs to be discharged from the smokehouse after smoking is completed.

[0003] To avoid the environmental impact of exhaust fumes, traditional smoking ovens are equipped with filtration structures. However, these filtration structures are simple, and after frequent use, the filtration pressure is high. The subsequent cleaning or replacement of the filtration structure affects the ease of use of the smoking oven to some extent. Therefore, there is an urgent need for a self-cleaning smoking oven to solve the above problems.

[0004] For example, traditional filtration structures mostly rely on activated carbon for adsorption. The adsorption capacity of activated carbon depends on the huge specific surface area provided by its porous structure. Pollutants such as tar particles, VOCs, and acidic gases contained in smoke residue will occupy the active sites of activated carbon through physical adsorption or chemical adsorption. High-frequency use will cause these pollutants to quickly fill the micropores, leading to adsorption saturation. Summary of the Invention

[0005] This invention discloses a self-cleaning smoking oven device, which aims to solve the technical problem that traditional smoking oven devices have simple filter structures. After frequent use of the smoking oven, the filter pressure is relatively high, and the subsequent cleaning or replacement of the filter structure will affect the convenience of using the smoking oven to a certain extent.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A self-cleaning smoke and grill oven includes an oven body and a smoke generating box. A smoke guide pipe and a return pipe are provided between the smoke generating box and the oven body. A fixing groove is provided on the top inner wall of the oven body. A pre-filtering mechanism is provided inside the fixing groove. A diversion and air guiding mechanism is connected to both sides of the fixing groove. A motor is provided on the top of the oven body. A rotating rod is connected to the output end of the motor. A self-cleaning mechanism is connected to the rotating rod. A purification mechanism is provided on one side of the oven body. The purification mechanism includes a fixed box disposed on one side of the furnace body. A flue pipe is provided on one side of the fixed box. One end of the flue pipe is connected to an inclined pipe. The end of the inclined pipe that passes through the furnace body is connected to a connector pipe. A second filter cover is screwed onto the connector pipe. A first adsorption box is installed on the top of the fixed box by screws. Two slide rails are provided on one side of the furnace body. A second adsorption box is provided on the top of the two first adsorption boxes. Slider blocks are provided on both sides of the second adsorption box. The second adsorption box is connected to the slide rails through the sliders. The bottom of the second adsorption box is fitted onto the top of the first adsorption box. An air pump is mounted on the outer wall of the second adsorption box near the top. The air inlet of the air pump communicates with the interior of the second adsorption box. An electrostatic dust removal component is provided inside the first adsorption box. Activated carbon is provided inside the second adsorption box. A flue gas outlet is provided at the outlet of the air pump.

[0007] In this design, a combined purification structure is formed by setting up a fixed box, a first adsorption box, and a second adsorption box. After the smokehouse is used, the remaining smoke can enter the exhaust pipe through the connector pipe. At this time, large tar particles will be filtered by the second filter cover. The filtered smoke then passes through the exhaust pipe and enters the first and second adsorption boxes in sequence through the fixed box. In the first adsorption box, electrostatic adsorption is used to remove small particles from the smoke. When passing through the second adsorption box, the activated carbon inside can further purify the smoke through physical and chemical adsorption. Finally, the purified smoke is discharged. In this process, the pre-filtration of the second filter cover combined with the first adsorption box greatly reduces the filtration pressure of a single filter structure and reduces the frequency of activated carbon replacement, making the smokehouse more environmentally friendly and convenient to use.

[0008] In a preferred embodiment, the electrostatic dust removal assembly includes a baffle disposed on the inner wall of the fixed box, with equally spaced metal rods mounted on the top of the baffle, and equally spaced dispersion holes on the baffle, the dispersion holes being staggered with the metal rods, the top of the metal rods extending into the interior of the first adsorption box, the inner wall of the first adsorption box being provided with a dust collection metal plate, and the connection between the fixed box and the furnace body being a detachable structure.

[0009] The electrostatic precipitator can further remove particulate pollutants in the flue gas that were not filtered by the second filter. During the power-on process, the metal rod and the dust collection metal plate carry opposite charges, which simultaneously causes the particulate pollutants to become charged, thus creating an adsorption effect. After the power is turned off, the adsorbed particles will fall into the fixed box for collection. The detachable installation of the fixed box allows for periodic emptying and disposal.

[0010] In a preferred embodiment, the pre-filtration mechanism includes a collection drawer disposed on the inner wall of the fixed groove, the collection drawer having a notch on one side, the fixed groove having a central protrusion and two concave sides, the collection drawer being adapted to the shape of the fixed groove, the collection drawer having a sandwich panel on both sides of the top outer wall of the collection drawer, and the fixed groove having a first filter cover on both sides of the inner wall.

[0011] The pre-filtration mechanism filters the flue gas poured into the fixed trough through the flue pipe, removing tar particles and preventing excessive accumulation of flue gas during the circulation process between the smoke generating box and the furnace body. This prevents the flue gas from adhering to the inner walls of the flue pipe and the return pipe. The jacketed plate inside the collection drawer has a perforated surface and a hollow interior structure. The flue gas entering the fixed trough is diverted to both sides by the central protrusion and then directly impacts the jacketed plate. Large tar particles in the flue gas are collected in the jacketed plate, while the flue gas passes through the first filter covers on both sides before entering the furnace body. The large tar particles collected in the jacketed plate can be cleaned periodically with the removal of the collection drawer. The easy disassembly and assembly of the collection drawer allows for simple pre-cleaning, reducing the pressure on subsequent residual smoke purification.

[0012] In a preferred embodiment, the gas diversion mechanism includes diversion holes disposed on both sides of the fixed groove, and diversion boxes are provided on both sides of the top of the furnace body. The two diversion boxes are respectively connected to the interior of the fixed groove through the two diversion holes. The bottom inner walls of the two diversion boxes are provided with equally spaced smoke holes. The interior of the furnace body is provided with a cavity, and the top inner walls of the cavity are provided with equally spaced smoke inlet pipes on both sides. The smoke holes are connected to the smoke inlet pipes.

[0013] The diversion and air guiding mechanism can divert the flue gas introduced by the flue pipe from the fixed groove, so that it enters the interior of the cavity through two diversion boxes, ensuring the uniformity of the smoke.

[0014] In a preferred embodiment, the self-cleaning mechanism includes a water inlet pipe disposed on one side of the furnace body, a drain pipe disposed on the side of the furnace body near the bottom, the drain pipe communicating with the cavity, an annular groove disposed inside the furnace body, one end of the water inlet pipe communicating with the inner wall of the annular groove, a connecting groove disposed on the inner wall of the rotating rod near the bottom, a mixing rod disposed on the outer circumference of the rotating rod near the bottom with equidistantly distributed circumferentially arranged, a fan plate disposed at the bottom of the mixing rod, spray holes disposed on both sides of the outer wall of the mixing rod with equidistantly distributed, the mixing rod being hollow inside and communicating with the connecting groove, and through holes disposed on the outer wall of the rotating rod with equidistantly distributed, the annular groove communicating with the connecting groove through the through holes.

[0015] The self-cleaning mechanism automatically cleans the interior of the smoking oven after use. Specifically, the cleaning solution is prepared and pumped into the inlet pipe. Simultaneously, the motor is started, driving the rotating rod to rotate the mixing rod and fan plate. When the cleaning solution is not flowing, the rotation of the fan plate mixes and agitates the smoke introduced into the oven, making the smoking more even and thorough. During the cleaning phase, the cleaning solution enters the annular groove through the inlet pipe, then through the through hole into the connecting groove inside the mixing rod, and finally sprays out through the spray holes on the mixing rod connected to the connecting groove. During this process, as the mixing rod rotates along with the rotating rod, the cleaning solution is fully sprayed onto the inner wall of the oven, effectively covering the oil stains from smoking inside the oven. Finally, the cleaning solution is replaced with clean water for a final cleaning, and the wastewater generated during cleaning is discharged through the drain pipe. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 1 to 12 A self-cleaning smoke and grill oven device includes an oven body 1 and a smoke generating box 2. A smoke guide pipe 7 and a return pipe 9 are provided between the smoke generating box 2 and the oven body 1. A fixing groove 20 is provided on the top inner wall of the oven body 1. A pre-filtering mechanism is provided inside the fixing groove 20. A diversion and air guiding mechanism is connected to both sides of the fixing groove 20. A motor 6 is provided on the top of the oven body 1. A rotating rod 25 is connected to the output end of the motor 6. A self-cleaning mechanism is connected to the rotating rod 25. A purification mechanism is provided on one side of the oven body 1. The purification mechanism includes a fixed box 16 located on one side of the furnace body 1. A flue pipe 8 is provided on one side of the fixed box 16. One end of the flue pipe 8 is connected to an inclined pipe 31. One end of the inclined pipe 31, which passes through the furnace body 1, is connected to a connector pipe 35. A second filter cover 10 is screwed onto the connector pipe 35. A first adsorption box 34 is installed on the top of the fixed box 16 by screws. Two slide rails are provided on one side of the furnace body 1. A second adsorption box 32 is provided on the top of the two first adsorption boxes 34. Slider 33 is provided on both sides of the second adsorption box 32. The second adsorption box 32 is connected to the slide rails through the slider 33. The bottom of the second adsorption box 32 is fitted onto the top of the first adsorption box 34. An air pump is installed on the outer wall of the second adsorption box 32 near the top. The air inlet of the air pump is connected to the interior of the second adsorption box 32. An electrostatic dust removal component is provided inside the first adsorption box 34. Activated carbon is provided inside the second adsorption box 32. A flue gas outlet 30 is provided at the outlet of the air pump.

[0031] Specifically, a combined purification structure is formed by setting a fixed box 16, a first adsorption box 34, and a second adsorption box 32. After the smoking oven is used, the remaining smoke can enter the exhaust pipe 8 through the connector pipe 35. At this time, large tar particles will be filtered by the second filter cover 10. The filtered smoke will then pass through the fixed box 16 through the exhaust pipe 8 and enter the first adsorption box 34 and the second adsorption box 32. In the first adsorption box 34, the small particles in the smoke will be adsorbed and cleaned through electrostatic adsorption. When passing through the second adsorption box 32, the activated carbon inside can further purify the smoke through physical and chemical adsorption. Finally, the purified smoke is discharged. In this process, the pre-filtration of the second filter cover 10 combined with the first adsorption box 34 greatly alleviates the filtration pressure of a single filter structure and reduces the frequency of activated carbon replacement, making the smoking oven more environmentally friendly and convenient to use.

[0032] The furnace body 1 has an installation hole 11 on its top. One end of the smoke guide pipe 7 is connected to the smoke generating box 2, and the other end of the smoke guide pipe 7 is connected to the interior of the fixing groove 20 through the installation hole 11.

[0033] It should be noted that the electrostatic dust removal assembly includes a baffle 42 disposed on the inner wall of the fixed box 16. The top of the baffle 42 is equipped with metal rods 39 that are evenly distributed. The baffle 42 is provided with dispersion holes 43 that are evenly distributed. The dispersion holes 43 and the metal rods 39 are staggered. The top of the metal rods 39 extends into the interior of the first adsorption box 34. The inner wall of the first adsorption box 34 is provided with a dust collection metal plate. The connection between the fixed box 16 and the furnace body 1 is a detachable structure.

[0034] Specifically, the dust removal by the electrostatic precipitator can further clean up particulate pollutants in the flue gas that have not been filtered by the second filter hood 10. During the power-on process, the metal rod 39 and the dust collection metal plate carry opposite charges, which simultaneously causes the particulate pollutants to become charged, thereby forming an adsorption effect. After the power is turned off, the adsorbed particles will fall into the fixed box 16 for collection. The detachable installation of the fixed box 16 allows for periodic emptying and disposal.

[0035] In addition, the top of the first adsorption box 34 is provided with a fixing plate 41, the top of the metal rod 39 is connected to the fixing plate 41, and the fixing plate 41 has equidistantly distributed air holes, which are staggered with the metal rod 39. The outer wall of the first adsorption box 34 near the bottom is provided with equidistantly distributed rubber strip rings 40. The bottom of the second adsorption box 32 is provided with a sleeve edge, which is used in conjunction with the rubber strip rings 40. The second adsorption box 32 is installed with the furnace body 1 through a sliding connection of slider 33 and slide rail, providing space for disassembly and assembly when the fixing box 16 and the first adsorption box 34 are disassembled and cleaned. At the same time, when the sleeve edge at the bottom of the second adsorption box 32 is sleeved onto the top of the first adsorption box 34, the inner wall of the sleeve edge will squeeze the rubber strip ring 40 on the outside of the second adsorption box 32. The deformation of the rubber strip ring 40 supports the connection and achieves a good sealing effect, preventing smoke leakage.

[0036] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In a preferred embodiment, the pre-filtration mechanism includes a collection drawer 12 disposed on the inner wall of the fixing groove 20. The collection drawer 12 has a notch 29 on one side. The fixing groove 20 has a structure with a central protrusion and two concave sides. The shape of the collection drawer 12 is adapted to the fixing groove 20. Both sides of the top outer wall of the collection drawer 12 are provided with a sandwich plate 26. Both sides of the inner wall of the fixing groove 20 are provided with a first filter cover 23.

[0037] Specifically, the pre-filtration mechanism filters the flue gas poured into the fixed trough 20 through the flue gas guide pipe 7, removing tar particles and preventing excessive accumulation of flue gas during the circulation process between the smoke generating box 2 and the furnace body 1, which would then adhere to the inner walls of the flue gas guide pipe 7 and the return pipe 9. The sandwich plate 26 inside the collection drawer 12 has a hollow structure with perforated surfaces. The flue gas entering the fixed trough 20 is diverted to both sides by the central protrusion inside the fixed trough 20 and then directly impacts the sandwich plate 26. Large tar particles in the flue gas are collected in the sandwich plate 26, while the flue gas passes through the first filter covers 23 on both sides and then enters the furnace body 1. The large tar particles collected in the sandwich plate 26 can be cleaned periodically with the removal of the collection drawer 12. The easy disassembly and assembly of the storage drawer allows for simple pre-cleaning, reducing the pressure on the subsequent purification of residual smoke.

[0038] It should be noted that the notch 29 and the rotating rod 25 are compatible. When the collection drawer 12 is pulled out, the notch 29 ensures that the rotating rod 25 will not interfere with it.

[0039] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8In a preferred embodiment, the gas diversion mechanism includes diversion holes 22 disposed on both sides of the fixed groove 20, and diversion boxes 17 are provided on both sides of the top of the furnace body 1. The two diversion boxes 17 are respectively connected to the interior of the fixed groove 20 through the two diversion holes 22. The bottom inner walls of the two diversion boxes 17 are provided with equally spaced smoke holes. The interior of the furnace body 1 is provided with a cavity 4. The top inner walls of the cavity 4 are provided with equally spaced smoke inlet pipes 14 on both sides. The smoke holes are connected to the smoke inlet pipes 14.

[0040] Specifically, the diversion and air guiding mechanism can divert the flue gas introduced by the smoke guide pipe 7 from the fixed groove 20, so that it enters the cavity 4 from the two diversion boxes 17, ensuring the uniformity of the smoke.

[0041] The furnace body 1 is equipped with a cover plate on top, and the motor 6 is located on top of the cover plate. After a long period of use, the motor 6 on the cover plate can be removed, and the cover plate on the top of the furnace body 1 can be removed at the same time to expose the diversion box 17 and the fixing groove 20, so as to facilitate the cleaning and wiping of the first filter cover 23 inside the diversion box 17 and the fixing groove 20.

[0042] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10 In a preferred embodiment, the self-cleaning mechanism includes a water inlet pipe disposed on one side of the furnace body 1, a drain pipe 5 disposed on the side of the furnace body 1 near the bottom, the drain pipe 5 communicating with the cavity 4, an annular groove 21 disposed inside the furnace body 1, one end of the water inlet pipe communicating with the inner wall of the annular groove 21, a connecting groove 19 disposed on the inner wall of the rotating rod 25 near the bottom, a mixing rod 15 disposed on the outer circumferential wall of the rotating rod 25 near the bottom with equidistantly distributed circumferentially distributed, a fan plate 18 disposed at the bottom of the mixing rod 15, spray holes disposed on both sides of the outer wall of the mixing rod 15 with equidistantly distributed, the mixing rod 15 being hollow inside and communicating with the connecting groove 19, and through holes disposed on the outer wall of the rotating rod 25 with equidistantly distributed, the annular groove 21 communicating with the connecting groove 19 through the through holes.

[0043] Specifically, the self-cleaning mechanism automatically cleans the interior of the chamber 4 after the smoking oven is used. Specifically, the cleaning solution is prepared and pumped into the inlet pipe 13. Simultaneously, the motor 6 is started, driving the rotating rod 25 to rotate the mixing rod 15 and the fan plate 18. When the cleaning solution is not flowing, the rotation of the fan plate 18 mixes and agitates the smoke introduced into the chamber 4, making the smoking more even and thorough. During the cleaning phase, the cleaning solution enters the annular groove 21 through the inlet pipe 13, then through the through-hole into the connecting groove 19 inside the stirring rod, and finally sprays out through the spray holes on the mixing rod 15, which communicates with the connecting groove 19. During this process, as the mixing rod 15 rotates along with the rotating rod 25, the cleaning solution is fully sprayed onto the inner wall of the chamber 4, effectively covering the oil stains from smoking inside the chamber 4. Finally, the cleaning solution is replaced with clean water for a final cleaning, and the wastewater generated during cleaning is discharged through the drain pipe 5.

[0044] The connector pipe 35 is located diagonally below the mixing pipe. The bottom of the connector pipe 35 is provided with a drain hole 36. When the rotating rod 25 drives the spray hole on the mixing rod 15 to rotate and spray the cleaning liquid, the cleaning liquid can also cover the second filter cover 10 on the connector pipe 35. In conjunction with the inclined pipe 31 connected to the connector pipe 35, it can be ensured that the wastewater after cleaning can flow back to the bottom of the cavity 4 through the drain hole 36 and be discharged from the drain pipe 5 along with most of the wastewater, thus avoiding the problem of water accumulation inside the connector pipe 35 after cleaning.

[0045] Reference Figure 1 and Figure 2 In a preferred embodiment, the top of the smoke-generating box 2 is provided with a hopper 3. When the smoke-generating box 2 is working, the internal heating device will be activated, and wood chips and other smoke-generating materials will be put into the hopper 3. Under the action of high temperature heating, the materials will be incompletely burned to form smoke. The smoke enters the cavity 4 through the smoke guide pipe 7, and then returns to the smoke-generating box 2 through the cavity 4 via the return pipe 9, ensuring the circulating smoke during the operation of the smoking oven.

[0046] Working principle: During use, the material in the smoke generating box 2 generates smoke through heating, which enters the fixed groove 20 at the top of the furnace body 1 through the smoke guide pipe 7. The pre-filtration mechanism first intercepts large tar particles in the smoke. The diversion and guiding mechanism distributes the smoke evenly into the cavity 4 to achieve circulating smoking of food. After smoking, the residual smoke is treated by the purification mechanism. The residual smoke enters from the connector pipe 35, is initially filtered by the second filter cover 10, and then passes through the electrostatic dust removal component of the fixed box 16 to adsorb small particles. Then, the pollutants are deeply purified by the activated carbon in the second adsorption box 32. Finally, the smoke is discharged from the exhaust port 30 by the air pump to meet the standards. At the same time, the self-cleaning mechanism is activated. The motor 6 drives the rotating rod 25 to rotate the mixing rod 15. The cleaning liquid is injected into the ring groove 21 through the liquid inlet pipe 13 and sprayed onto the inner wall of the cavity 4 through the spray hole to automatically clean the oil stains. The wastewater is discharged through the drain pipe 5, realizing environmental protection and low maintenance operation throughout the process.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
