Abstract

This invention discloses a vehicle-mounted fuel-powered intelligent cooking machine, comprising a support body, a circulating water box for adding liquid water, and an outer barrel that can be flipped upside down. The outer barrel has a heating chamber on its inner side and an inner barrel that can be rotatably mounted thereon. A smoke exhaust mechanism is mounted on the support body and connected to the heating chamber, and is used to exhaust hot exhaust gas from inside the heating chamber. The heating plate absorbs heat and transfers it sequentially through heat exchange medium holes and heat conduction plates to a heat exchange particle layer. The heat exchange particle layer absorbs the heat from the absorbed hot exhaust gas a second time. The heat exchange arc plate can partially block the overflow of rising hot exhaust gas in the heating chamber, and at the same time, it can absorb the heat from the rising hot exhaust gas and transfer it to the liquid water in the heat exchange tube. The circulating liquid water is then heated a second time by the liquid guide coil and the heat exchange tube, which facilitates the use of the heat from the hot exhaust gas for heating the liquid water used for cleaning, and also prevents the hot exhaust gas from accumulating on the top surface of the inner barrel for a long time.

Description

Technical Field

[0001] This invention belongs to the field of cooking machine technology, specifically relating to a vehicle-mounted fuel-powered intelligent cooking machine. Background Technology

[0002] The vehicle-mounted intelligent fuel-powered cooking machine is mainly installed on cooking vehicles, using onboard fuel as an energy source for food processing. Relying on a built-in intelligent control system, it automatically completes processes such as heating, stirring, serving, and cleaning according to instructions, improving the efficiency of food processing and reducing the workload of operators. The equipment mainly consists of a support frame, inner and outer barrels, a fully automatic fuel burner, a drive motor, a flue, a water collection tray, insulation material, water and oil supply systems, an electrical control system, a fuel system, and a smoke exhaust system. The drive motor includes a forward and reverse stepper motor for the inner barrel, a barrel tilting speed control motor, a water pump, and an oil pump. These components receive program instructions and tilt and rotate the barrels during operation. The blackening of the pot bottom is due to natural gas. Natural gas is an organic gas whose main element is carbon. In cases of incomplete combustion, excess carbon accumulates at the bottom of the pot, forming a black layer.

[0003] For example, Chinese patent CN213850030U discloses a multi-functional drum cooking machine, including a base and a drum: an operation panel is located on the left side of the front of the base, with number keys 1-9, up and down buttons, and a power button; a control chip is located inside the base; and a display screen is located in the center of the front of the base; frames are installed on the left and right sides of the upper end of the base, and a mounting box is rotatably connected to the inner side of the upper end of the frame. The drum is rotatably mounted inside the mounting box and is driven by a motor installed at the bottom of the mounting box. A handle is located on the upper end of the right frame, and an infrared thermometer is installed on the upper end of the left frame. The patent describes the rotation and flipping mechanism of the drum cooking machine. Another example is Chinese patent CN211119580U, which discloses a drum... The stir-fry machine and automatic cooking equipment have a heat preservation structure. Inside, there is a heating chamber; around its perimeter, there are through-holes facing forward and backward; and on its top, there is a smoke outlet. The drum stir-fry machine includes a smoke collection hood and a smoke separator. The smoke collection hood is located on the top side of the drum and is used to collect smoke. The smoke collection hood has an open-mouth structure for collecting smoke and an exhaust port connecting the smoke collection chamber to the outside. The opening of the smoke collection chamber is connected to the exhaust port. The smoke separator is located in the smoke collection chamber and is used to divide the smoke collection chamber into a left exhaust channel and a right exhaust channel, which are set on the left and right sides and are independent of each other. Both the left and right exhaust channels connect the smoke collection chamber to the exhaust port. This effectively prevents smoke from accumulating on the top of the drum cooker, which can easily damage the cooker coating. Furthermore, it provides a high-heat environment to keep the food in the drum cooker warm.

[0004] However, the above solution has the following shortcomings: Although the smoke-proof component on the heating chamber between the insulation structure (outer barrel) and the drum cooker (inner barrel) prevents hot air from accumulating on the top of the outer surface of the inner barrel, it only directs the accumulated hot air to the smoke collection hood area and does not reuse the heat in the accumulated hot air. After use, existing cooking machines usually use a spray gun to spray liquid water into the inner barrel wall for cleaning. In order to improve the cleaning effect, the liquid water is heated by an external electric heating element before being sprayed out, which requires additional electricity. How to reuse the hot air in the heating chamber, so that the heat in the hot exhaust gas can be used to heat the liquid water for cleaning, while also preventing the hot exhaust gas from accumulating on the top of the inner barrel for a long time, is the direction that needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle-mounted fuel-powered intelligent cooking machine to solve the problems existing in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The top of the smoke exhaust pipe is connected to the air intake end of the range hood body, and the lower part of the side wall of the smoke exhaust pipe is connected to the hollow rotating shaft for rotational air guiding through a sealed bearing ring. When the inner barrel rotates clockwise or counterclockwise, the hollow rotating shaft and the smoke exhaust pipe are disposed on the left or right side of the inner barrel body.

[0013] Preferably, the air inlet end of the hollow flip shaft is provided with a main David flame arrestor to prevent the outer flame of the heating flame inside the heating chamber from entering the exhaust pipe.

[0014] Preferably, the external heat exchange assembly includes secondary David flame arresters symmetrically arranged inside the flue pipe. The space between adjacent secondary David flame arresters is filled with a heat exchange granular sphere layer that can accommodate the passage of hot exhaust gas. A heat-conducting plate is disposed within the heat exchange granular sphere layer and extends to the lower part below the secondary David flame arrester. A heat exchange medium hole filled with a heat exchange medium is provided on the side wall of the lower extension end of the heat-conducting plate. A heating plate penetrates through the side wall of the main David flame arrester. The heating plate contacts the outer flame of the burner flame and provides auxiliary heating. The heat absorbed by the heating plate passes through the heat exchange medium hole, the heat-conducting plate, and the heat exchange granular sphere layer in sequence.

[0015] Preferably, there is an anti-collision gap between the end of the heating plate extending into the heating chamber and the outer wall of the inner barrel, and the upper surface of the heating plate is provided with heat exchange mesh holes. The external heat exchange assembly also includes a liquid guiding coil arranged in a coiled manner within the heat exchange particle sphere layer. The liquid guiding coil is sleeved on the outside of the heat guiding plate, and the liquid inlet end of the liquid guiding coil is connected to the liquid outlet end of the water pump body.

[0016] Preferably, the outer barrel is provided with an inlet arc cavity, an expansion arc cavity, and a drain arc cavity in sequence. The drain end of the liquid guide coil is connected to the inlet arc cavity. The internal heat exchange assembly includes a liquid guide expansion arc tube disposed inside the expansion arc cavity. The drain end of the inlet arc cavity is connected to the inlet end of the liquid guide expansion arc tube. The upper part of the inner wall of the outer barrel is provided with a heat exchange arc groove located between the expansion arc cavity and the drain arc cavity. Heat exchange tubes are arranged along the arc direction inside the heat exchange arc groove, and the inlet and drain ends of the heat exchange tubes are respectively connected to the outlet end of the expansion arc tube and the inlet end of the drain arc cavity.

[0017] Preferably, the heat exchange arc groove is provided with heat exchange arc plates, the heat exchange tube passes through the heat exchange arc plates and is used to transfer the heat absorbed by the heat exchange tube, and there is a gap between adjacent heat exchange arc plates for heat exchange after the rising hot exhaust gas in the heating chamber flows in. The distance between the inner ring wall of the heat exchange arc plates and the outer surface of the inner barrel decreases sequentially from the direction towards the drain arc cavity. The drain side of the drain arc cavity is connected to the circulating water box through a return pipe, and the return pipe is connected to the cleaning water gun through a valve body.

[0018] Preferably, the outer wall of the main fire-retardant mesh is provided with a scraping arc plate spaced apart from the outer surface of the inner barrel. The scraping arc plate has a drain chamber with a drain hole on its side wall, and fireproof cotton is detachably sleeved on the scraping arc plate. The drain end of the liquid guide coil is connected to the drain chamber through an electric control valve. The opening and closing of the electric control valve is controlled by an external intelligent control terminal. After the electric control valve is opened for T seconds, some circulating water is discharged through the drain chamber into the fireproof cotton for wetting. As the inner barrel rotates, the fireproof cotton cleans the black scale formed by carbon deposits on the outer surface of the inner barrel.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the heat absorbed by the heating plate is transferred to the heat exchange particle ball layer through the heat exchange medium holes and the heat conduction plate in sequence.

The heat exchange arc plate can partially block the overflow of the rising waste gas in the heating chamber, and at the same time, it can absorb the heat in the rising waste gas and transfer it to the liquid water in the heat exchange tube. The circulating liquid water is heated a second time through the liquid guide coil and the heat exchange tube in sequence. This makes it convenient to use the heat in the waste gas to heat the liquid water for cleaning, while also preventing the waste gas from accumulating on the top surface of the inner barrel for a long time.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figure 1-9 The present invention provides a technical solution:

[0032] Example 1:

[0033] A vehicle-mounted fuel-powered intelligent cooking machine includes:

[0034] The support body 1 is provided with a circulating water box 101 that can be filled with liquid water and an outer barrel 2 that can be flipped. The inner side of the outer barrel 2 has a heating chamber 3 and an inner barrel 4 that can be rotated.

[0035] A smoke exhaust mechanism is mounted on the support body 1 and connected to the heating chamber 3. The smoke exhaust mechanism is used to discharge hot exhaust gases from inside the heating chamber 3 along the side of the outer barrel 2.

[0036] The heat exchange mechanism includes an external heat exchange component and an internal heat exchange component that circulate with and are sequentially connected to the circulating water box 101. The heat absorption end of the external heat exchange component is set on the exhaust mechanism and is used to absorb the heat in the exhaust hot gas. The internal heat exchange component is set on the inner wall of the outer barrel 2 and is used to absorb the heat from the unheated area of ​​the inner barrel 4 relative to the hot exhaust gas in the heating chamber 3.

[0037] Example 2:

[0038] Based on Embodiment 1, a water pump body 5 is provided at the drain end of the circulating water box 101. An external inlet pipe is connected to the circulating water box 101 via a shut-off valve. The inlet pipe, connected to an external water source, is used to replenish liquid water into the circulating water box 101. The bottom of the outer barrel 2 is designed to be open and is used to install the burner 301 below to generate a flame to heat the outer wall of the inner barrel 4. The burner 301 is designed with an adjustable load of 5-15kW. The combustion medium can be any one of natural gas, coal gas, and fuel oil. The burner 301 is adaptively adjusted according to different combustion media. In this embodiment, the burner 301 is a CX10-2 automatic fuel oil burner produced by Foshan Shunde Zhibo Combustion Engine Manufacturing Co., Ltd. A tilting motor 6 is provided on the side of the support body 1 for tilting the outer barrel 2. A rotary motor is pre-installed on the outer side of the bottom end face of the outer barrel 2. The rotating part of the output shaft of the rotary motor and the bottom of the inner barrel 4 insertion part are connected. The end face connection allows the rotary motor to drive the inner barrel 4 to rotate. The inner barrel 4, in cooperation with the outer barrel 2, achieves flipping and rotation, which is the content disclosed in the prior art announcement number CN213850030U and will not be elaborated further. A hollow flipping shaft 7 is provided on the side wall of the outer barrel 2 away from the flipping motor 6. The hollow flipping shaft 7 has a hollow structure and is connected to the inner side of the heating chamber 3. The water pump body 5, burner 301, flipping motor 6 and water pump body 5 are all connected to the external intelligent control terminal 401. The water pump body 5 is a circulating water pump. The flipping motor 6 and rotary motor can be selected from servo motors, disc motors and three-phase asynchronous motors as needed. The external intelligent control terminal 401 provides a variety of management interfaces through the touch screen. Users can observe the operation process in real time, including fault information, modify relevant parameters in the recipe to customize the dishes, upgrade and cancel the operation program, and access various statistical data at any time.

[0039] Combustion heating process:

[0040] The system initiates a cooking process via a touchscreen: the automatic fuel burner 301 starts, ignites, and burns normally (the flame size can be set automatically or manually depending on the program). Simultaneously, the inner drum 4 rotates, the food is fed in, the program is completed, the food is served, and the pot is washed. For details regarding the intelligent control terminal 401, please refer to the existing equipment of the intelligent drum cooking machine produced by Dongguan Maxison Electronics Co., Ltd.

[0041] Example 3:

[0042] Further elaborating on Embodiment 2, the smoke exhaust mechanism includes a smoke exhaust pipe 8 disposed on the side of the support body 1. A rotatable adjusting plate 201 is provided at the smoke exhaust port end of the smoke exhaust pipe 8 for adjusting the size of the smoke outlet. The top of the smoke exhaust pipe 8 is connected to the suction end of the range hood body 9. Adjusting the adjusting plate 201 allows the range hood body 9 to adjust the suction force on the smoke exhaust pipe 8, preventing excessive suction on the smoke exhaust pipe 8 from causing significant dispersion of the heating flame path inside the heating chamber 3. The lower part of the side wall of the smoke exhaust pipe 8 has an open annular groove, and the open annular groove on the lower part of the side wall of the smoke exhaust pipe 8 is connected to the hollow rotating shaft 7 by a sealed bearing ring 10. A rotating air guide connection is made, and the gap between the sealing bearing ring 10 and the open annular groove is filled with a sealing ring. When the inner barrel 4 rotates clockwise or counterclockwise, the hollow flip shaft 7 and the exhaust pipe 8 are located on the left or right side of the inner barrel 4. Specifically, when the inner barrel 4 rotates clockwise, the food inside the inner barrel 4 will accumulate to the left as it rotates. Therefore, when the hollow flip shaft 7 and the exhaust pipe 8 are located on the left side, the local negative pressure suction generated by the exhaust pipe 8 can draw in the hot exhaust gas inside the heating chamber 3, and can also cause the heating flame inside the heating chamber 3 to concentrate on the left side, thereby concentrating the heating of the food accumulated to the left side.

[0043] The hollow rotating shaft 7 has a main David flame arrestor mesh 11 at its air inlet end, which is used to prevent the outer flame of the heating flame inside the heating chamber 3 from entering the exhaust pipe 8. Specifically, it can be explained according to the principle of the David lamp. The flame of the candle cannot ignite the gas outside the metal mesh because the good thermal conductivity of the metal mesh makes the temperature outside the mesh not reach the ignition point of the gas. It should be noted that when the flame inside the heating chamber 3 continuously heats the main David flame arrestor mesh 11, its flame arresting effect will decrease due to the reduced thermal conductivity. Therefore, multiple main David flame arrestor meshes 11 can be arranged in parallel, or the heat absorbed by the main David flame arrestor mesh 11 can be dissipated. The main David flame arrestor mesh 11 can be connected to an external heat sink, such as connecting the cooling end of the semiconductor cooling chip to the heat dissipation extension end of the main David flame arrestor mesh 11, thereby improving the thermal conductivity of the main David flame arrestor mesh 11 and ensuring the flame arresting effect.

[0044] Example 4:

[0045] Based on Embodiment 3, the external heat exchange assembly includes secondary David flame arresters 12 symmetrically arranged inside the exhaust pipe 8. The spaces between adjacent secondary David flame arresters 12 are filled with heat exchange granular spheres 13 capable of accommodating hot exhaust gas. The heat exchange granular spheres 13 are selected from ceramic spheres with high temperature resistance and thermal conductivity, with a sphere diameter of 2 cm. A gap of at least 3 mm is required between the spheres. Therefore, the shape of the ceramic spheres can be adaptively adjusted. Furthermore, the heat exchange granular spheres 13 are not limited to ceramic spheres; only those with high temperature resistance are acceptable. The secondary David flame arrestor 12 provides secondary protection against flames that may penetrate the exhaust pipe 8, while the heat exchange particle sphere layer 13 provides tertiary protection against such flames. A heat-conducting plate 14 is installed within the heat exchange particle sphere layer 13 and extends below the secondary David flame arrestor 12. The heat-conducting plate 14 is made of copper or aluminum alloy, and its lower extended sidewall has heat exchange medium holes 15 filled with heat exchange medium. A heat-receiving plate penetrates the sidewall of the main David flame arrestor 11. 16. A gap exists between the main David flame arrestor 11 and the heating plate 16, filled with a layer of insulating material. The insulating material can be selected from glass wool or asbestos. The insulating material layer reduces heat transfer and dissipation between the heating plate 16 and the main David flame arrestor 11. The heating plate 16 contacts the outer flame of the burner 301 and provides auxiliary heating. The heat transfer end of the heating plate 16 has a cylindrical structure, which is inserted into the heat exchange medium hole 15 using a stuffing box. The stuffing box is a device installed where the rotating shaft or reciprocating rod of the machine passes through the fixed part of the machine. The sealing device can prevent leakage of gas or liquid materials; in this embodiment, the cylindrical end of the heating plate 16 can rotate after being inserted into the heat exchange medium hole 15. The stuffing box is designed to prevent leakage of the heat exchange medium packing. The packing can be selected from any one of alumina, magnesium oxide, zinc oxide, aluminum nitride, boron nitride, and silicon carbide. The specific arrangement of the stuffing box relative to the heat exchange medium hole 15 is the prior art and will not be described in detail. The heating end of the heating plate 16 is an extended design, forming a T-shaped structure, which can cover the flame heating area inside the heating chamber 3.

[0046] Furthermore, the heat absorbed by the heat plate 16 passes through the heat exchange medium hole 15, the heat conduction plate 14 and the heat exchange particle sphere layer 13 in sequence, while the heat exchange particle sphere layer 13 can absorb the heat in the heat exhaust gas.

[0047] The heating plate 16 extends into the heating chamber 3 and has an anti-collision gap A between its end and the outer wall of the inner barrel 4. The gap A is controlled at 7mm. The upper surface of the heating plate 16 is provided with heat exchange mesh 17. The heat exchange mesh 17 can increase the heat exchange area of ​​the heating plate 16. Since the heat exchange mesh 17 can attract part of the flame flow in the heating chamber 3, it can also reduce the amount of flame passing through the gap A. The external heat exchange assembly also includes a liquid guide coil 18 arranged in a coiled manner in the heat exchange particle ball layer 13. The liquid guide coil 18 is sleeved on the outside of the heat conduction plate 14, and the liquid inlet end of the liquid guide coil 18 is connected to the liquid outlet end of the water pump body 5. The liquid guide coil 18 absorbs the heat obtained inside the heat exchange particle ball layer 13 and also plays a role in cooling the heat exchange particle ball layer 13.

[0048] Example 5:

[0049] Based on Embodiment 4, the outer barrel 2 is provided with an inlet arc cavity 19, an expansion arc cavity 20, and a drain arc cavity 21 connected in sequence. The drain end of the liquid guide coil 18 is connected to the inlet arc cavity 19. The internal heat exchange assembly includes a liquid guide expansion arc tube 22 disposed inside the expansion arc cavity 20. The liquid guide expansion arc tube 22 is a corrugated steam pipe expansion joint, which can solve the stress and deformation problems caused by the length change of the steam pipe due to temperature changes. The drain end of the inlet arc cavity 19 is connected to the inlet end of the liquid guide expansion arc tube 22. The upper part of the inner wall of the outer barrel 2 is provided with a heat exchange arc groove 23 located between the expansion arc cavity 20 and the drain arc cavity 21. Heat exchange tubes 24 are arranged along the arc direction inside the heat exchange arc groove 23, and the inlet and drain ends of the heat exchange tubes 24 are respectively connected to the outlet end of the liquid guide expansion arc tube 22 and the inlet end of the drain arc cavity 21.

[0050] Heat exchange arc plates 25 are arranged inside the heat exchange arc groove 23. Heat exchange tubes 24 pass through the heat exchange arc plates 25 and are used to transfer the heat absorbed by the heat exchange tubes 24. Both the heat exchange tubes 24 and the heat exchange arc plates 25 are made of thermally conductive metal materials, specifically aluminum alloy or copper. There are gaps between adjacent heat exchange arc plates 25 to facilitate heat exchange after the rising hot exhaust gas flows into the heating chamber 3, and to decelerate the rising hot exhaust gas. The distance between the inner ring wall of the heat exchange arc plates 25 and the outer surface of the inner barrel 4 decreases sequentially from the direction towards the drain arc cavity 21. The minimum distance between the inner ring wall of the heat exchange arc plates 25 and the outer surface of the inner barrel 4 is 3mm. The above arrangement can reduce the amount of hot exhaust gas discharged from the heat exchange arc plates 25 side inside the heating chamber 3. For details, please refer to:

[0051] Regarding the description of the labyrinth seal in https: / / www.toutiao.com / article / 7084146717985096224 / ?channel=&source=search_tab, it should be noted that in this embodiment, the minimum distance between the inner ring wall of the heat exchange arc plate 25 and the outer surface of the inner barrel 4 is set to 3mm. This allows a portion of the hot exhaust gas inside the heating chamber 3 to be discharged. The purpose of this gap setting is to reduce the amount of hot exhaust gas discharged from the opening side of the heating chamber 3, so as to facilitate continuous heat exchange between the hot exhaust gas and the inner barrel 4.

[0052] The discharge arc cavity 21 is connected to the circulating water box 101 via the return pipe 26, and the return pipe 26 is connected to the cleaning water gun 28 via the valve body 27. The valve body 27 is a two-position three-way valve and controls the opening and closing of the water inlet of the cleaning water gun 28. The cleaning water gun 28 can generate high pressure water by using a power device to drive a high pressure plunger pump to rinse the surface of the object. It can peel off and wash away dirt to achieve the purpose of cleaning the surface of the object.

[0053] In another embodiment, the cleaning water gun 28 can also be a separate spray head without a high-pressure plunger pump, which can spray out the heat-exchanged liquid water through the cleaning water gun 28 by turning on the water pump body 5.

[0054] Example 6:

[0055] The outer wall of the main fire-resistant mesh 11 is provided with a scraping arc plate 29 spaced apart from the outer surface of the inner barrel 4. The scraping arc plate 29 has a drain chamber 30 with a drain hole on its side wall, and fireproof cotton 31 is detachably sleeved on the scraping arc plate 29. The drain end of the liquid guide coil 18 is connected to the drain chamber 30 through an electric control valve 32. The electric control valve 32 is an electromagnetic water valve. The opening and closing of the electric control valve 32 is controlled by an external intelligent control terminal 401. After the electric control valve 32 is opened for T seconds, some circulating water is discharged through the drain chamber 30 into the fireproof cotton 31 for wetting. As the inner barrel 4 rotates, the fireproof cotton 31 cleans the black dirt formed by carbon deposits on the outer surface of the inner barrel 4, achieving a cleaning effect and keeping the hard-to-clean parts of the outer wall of the inner barrel 4 clean.

[0056] The working principle is as follows: The bracket body 1 of the present invention is installed in the vehicle's pre-set space. The user can preset the processing parameters, taste parameters, compensation parameters, burner parameters, food output and pot washing parameters, etc., through the touch screen on the external intelligent control terminal 401 as needed. Then the corresponding recipe program will run according to the user's settings. The water pump body 5, the flip motor 6, the rotary motor, the range hood body 9, the electric control valve 32, and the external intelligent control terminal 401 are connected to an external power supply.

[0057] The inner barrel 4 is tilted and rotated under the action of the tilting motor 6 and the rotating motor. The burner 301 is ignited and heats the inner barrel 4 through the bottom opening of the outer barrel 2. The rotation of the inner barrel 4 is uniformly heated by the flame injected into the lower part of the heating chamber 3. The outer flame of the injected flame heats the heating plate 16, and the heat absorbed by the heating plate 16 is transferred to the heat exchange granular sphere layer 13 through the heat exchange medium hole 15 and the heat conduction plate 14. At the same time, the adjustment of the regulating plate 201 adjusts the suction of the exhaust pipe 8. The hot exhaust gas inside the heating chamber 3 is discharged through the main David flame arrester 11, the secondary David flame arrester 12 and the heat exchange granular sphere layer 13. 13. The heat in the inhaled hot exhaust gas is absorbed a second time. When the water pump body 5 is working, the liquid water inside the circulating water box 101 can be circulated sequentially through the liquid guide coil 18, the liquid inlet arc cavity 19, the liquid guide expansion arc tube 22, the heat exchange tube 24, the liquid outlet arc cavity 21 and the return pipe 26. The heat exchange arc plate 25 can partially block the overflow of the rising hot exhaust gas in the heating chamber 3, and can also absorb the heat in the rising hot exhaust gas and transfer it to the liquid water in the heat exchange tube 24. This allows the circulating liquid water to be heated a second time through the liquid guide coil 18 and the heat exchange tube 24. This makes it convenient to use the heat in the hot exhaust gas to heat the cleaning liquid water, and also prevents the hot exhaust gas from accumulating on the top surface of the inner barrel 4 for a long time.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
