Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a cooking utensil. Background Art

[0002] At present, all pressure baking pans share one exhaust channel, but baking cooking and conventional cooking have different requirements for exhaust. When baking cooking, the cooking appliance needs to be vented while taking in air to ensure the circulation of gas in the cooking appliance. Conventional cooking requires that hot air be discharged directly without taking in air. It is difficult to achieve two exhaust methods through one exhaust channel.

[0003] That is to say, there is a problem that the two exhaust modes of the cooking utensils in the prior art are incompatible. Summary of the invention

[0004] The main purpose of the present invention is to provide a cooking appliance to solve the problem that two exhaust modes of the cooking appliance in the prior art are incompatible.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a cooking utensil, including a pot cover, a pot body and an inner cover, wherein the pot cover can be opened and closed on the pot body, the pot body has a heating structure, and the pot cover comprises: a cover body; a baking assembly, the baking assembly is arranged below the cover body, an exhaust passage is arranged on the cover body, the interior of the cooking utensil is connected with the outside through the exhaust passage, the inner cover can be detachably mounted on the cover body and is located below the baking assembly; an exhaust hood, the exhaust hood can be detachably mounted at any one of the two ends of the exhaust passage, wherein the exhaust hood is assembled at the bottom end of the exhaust passage when the inner cover is disassembled, and is assembled at the top end of the exhaust passage after the inner cover is installed.

[0006] By setting an exhaust channel on the pot cover, the hot air in the cooking utensil can be discharged to the outside of the cooking utensil. The setting of the baking component enables the cooking utensil to perform baking and cooking, and the setting of the inner cover enables the cooking utensil to perform conventional cooking, which increases the diversity of the use of the cooking utensil. The baking cooking mode requires air intake and exhaust at the same time. During baking cooking, the exhaust hood is installed below the exhaust channel, which can reduce the speed of gas flowing out of the cooking utensil, so that the high-temperature gas circulates in the cooking utensil for a longer time, thereby increasing the baking efficiency. And the exhaust hood does not block the top of the exhaust channel, and does not affect the air intake of the exhaust channel, so as to ensure the circulation of gas during baking of the cooking utensil. In the conventional cooking mode, it is necessary to continuously exhaust the gas inside the cooking utensil. The exhaust hood is installed on the top of the exhaust channel, which can make way for the inner cover, facilitate the installation of the inner cover, and at the same time reduce the gas from the top of the exhaust channel into the interior of the cooking utensil, so as to ensure that the gas inside the cooking utensil is quickly discharged and ensure the stability of conventional cooking work.

[0007] Further, the exhaust hood has an exhaust hole, and the exhaust hood is sealed and connected to the exhaust passage. The exhaust hood and the exhaust passage are sealed and connected to each other, which can reduce the gas from entering the area between the exhaust hood and the exhaust passage.

[0008] Furthermore, the side wall of the exhaust channel has a first through hole, and when the exhaust hood is mounted on the bottom end of the exhaust channel, the first through hole is connected to the exhaust channel; when the exhaust hood is mounted on the top end of the exhaust channel, the exhaust hood blocks the first through hole. This arrangement can prevent the humid gas in the pot from entering the first through hole when the cooking utensil is used for conventional cooking, thereby ensuring that the structure in the first through hole is not damp and can work stably.

[0009] Furthermore, the cooking appliance further comprises an air intake conduction structure, the air intake conduction structure has an air intake channel, and the first through hole is connected to the internal space of the baking component through the air intake conduction structure. The air intake conduction structure can plan the flow direction of the gas to ensure that the gas only enters the internal space of the baking component, reduce the accumulation of gas in the cover body, avoid the moisture in the gas from affecting the internal electrical components of the cover body, increase the stability and safety of the cover body, and reduce safety hazards.

[0010] Furthermore, the side wall of the exhaust passage has a second through hole, and when the exhaust hood is mounted at the bottom end of the exhaust passage, the exhaust hood blocks the second through hole; when the exhaust hood is mounted at the top end of the exhaust passage, the second through hole is connected to the exhaust passage. Switching the position of the exhaust hood can cause the second through hole to be opened or closed, so that the second through hole works or does not work, while preventing gas from entering the second through hole.

[0011] Furthermore, the inner cover has a pressure-limiting valve assembly, the pressure-limiting valve assembly extends into the exhaust passage, the pressure-limiting valve assembly is located at the second through hole, and the cover body includes a push rod extending from the second through hole, so that the push rod can operate the pressure-limiting valve assembly. When the exhaust hood is installed at the top end of the exhaust passage, the second through hole is communicated with the exhaust passage, so that the push rod can extend from the second through hole to push the pressure-limiting valve assembly, so that the internal gas of the cooking appliance is discharged through the pressure-limiting valve assembly.

[0012] Furthermore, the outer wall of the exhaust hood has a first limiting structure, and the side wall of the exhaust passage has a second limiting structure that cooperates with the first limiting structure. When the exhaust hood is installed on the exhaust passage, the first limiting structure and the second limiting structure are engaged. The mutual cooperation between the first limiting structure and the second limiting structure enables the exhaust hood to be stably installed in the exhaust passage, reduces the possibility of the exhaust hood being separated from the exhaust passage, and increases the working stability of the exhaust hood.

[0013] Furthermore, the first limiting structure is a limiting protrusion, and the second limiting structure is a limiting groove; or the first limiting structure is a limiting groove, and the second limiting structure is a limiting protrusion. This arrangement facilitates the assembly between the first limiting structure and the second limiting structure, and the first limiting structure and the second limiting structure are not easy to separate, so as to ensure the working stability of the exhaust hood.

[0014] Furthermore, the pot cover also includes a sealing structure, which is sleeved on the outer wall of the exhaust hood and is located above the first limiting structure. The sealing structure is clamped between the exhaust hood and the exhaust channel and seals the gap between the first limiting structure and the second limiting structure. After the first limiting structure and the second limiting structure are assembled together, there is a certain gap between the first limiting structure and the second limiting structure to facilitate the assembly between the first limiting structure and the second limiting structure.

[0015] Furthermore, the exhaust hood has a stop flange, which is located at one end of the exhaust hood. When the exhaust hood is mounted on the top of the exhaust passage, the stop flange overlaps the surface cover of the cover body and forms a seal with the surface cover; when the exhaust hood is mounted on the bottom of the exhaust passage, the stop flange abuts against the reflective cover of the cover body and forms a seal with the reflective cover. The setting of the stop flange can form a seal on part of the structure of the exhaust passage to reduce the impact of gas on the exhaust passage.

[0016] Furthermore, the pot cover also includes a sealing structure, which is sleeved on the outer wall of the exhaust hood, the outer wall of the exhaust hood has a first clamping convex edge, the inner wall of the exhaust channel has a second clamping convex edge that matches the sealing structure, and the sealing structure is clamped between the first clamping convex edge and the second clamping convex edge. The sealing structure is clamped between the first clamping convex edge and the second clamping convex edge to prevent the sealing structure from falling off, and ensure that the sealing structure can stably seal the gap between the exhaust hood and the exhaust channel.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0038] In order to solve the problem that two exhaust modes of cooking utensils in the prior art are incompatible, the present invention provides a cooking utensil.

[0039] like Figures 1 to 15 As shown, the cooking utensil comprises a pot cover 1, a pot body 2 and an inner cover 3. The pot cover 1 can be opened and closed on the pot body 2. The pot body 2 has a heating structure. The pot cover 1 comprises a cover body 4, a baking component 5 and an exhaust hood 7. The baking component 5 is arranged below the cover body 4. The cover body 4 is provided with an exhaust passage 6. The interior of the cooking utensil is connected with the outside through the exhaust passage 6. The inner cover 3 is detachably mounted on the cover body 4 and is located below the baking component 5; the exhaust hood 7 is detachably mounted on any one of the two ends of the exhaust passage 6, wherein the exhaust hood 7 is assembled at the bottom end of the exhaust passage 6 when the inner cover 3 is disassembled, and the exhaust hood 7 is assembled at the top end of the exhaust passage 6 after the inner cover 3 is installed.

[0040] By setting the exhaust channel 6 on the pot cover 1, the hot air in the cooking utensil can be discharged to the outside of the cooking utensil. The setting of the baking component 5 enables the cooking utensil to perform baking and cooking, and the setting of the inner cover 3 enables the cooking utensil to perform conventional cooking, which increases the diversity of the use of the cooking utensil. The baking cooking mode requires air intake and exhaust at the same time. During baking cooking, the exhaust hood 7 is installed below the exhaust channel 6, which can reduce the speed of gas flowing out of the cooking utensil, so that the high-temperature gas circulates in the cooking utensil for a longer time, thereby increasing the baking efficiency. And the exhaust hood 7 does not block the top of the exhaust channel 6, and does not affect the air intake of the exhaust channel 6, so as to ensure the circulation of gas during baking of the cooking utensil. In the conventional cooking mode, it is necessary to continuously discharge the gas inside the cooking utensil. The exhaust hood 7 is installed on the top of the exhaust channel 6, which can make way for the inner cover 3, facilitate the installation of the inner cover 3, and at the same time reduce the gas from the top of the exhaust channel 6 into the interior of the cooking utensil, so as to ensure that the gas inside the cooking utensil is quickly discharged and ensure the stability of conventional cooking work.

[0041] like Figures 1 to 4 As shown, the exhaust hood 7 has an exhaust hole 16, and the exhaust hood 7 is sealed and connected to the exhaust channel 6. The exhaust hood 7 is sealed and connected to the exhaust channel 6 to reduce the gas from entering the area between the exhaust hood 7 and the exhaust channel 6. Since the cooking utensils will generate a lot of oil stains when baking and cooking, the setting of the exhaust hood 7 can reduce the accumulation of oil stains in the exhaust channel 6, and the oil stains accumulated in the exhaust channel 6 are not easy to clean and are prone to produce odor. The exhaust hood 7 is sealed and connected to the exhaust channel 6, which can reduce the oil stain steam entering the exhaust channel 6, and the oil stain steam is discharged through the exhaust hole 16 on the exhaust hood 7, which increases the user experience. Since the exhaust hood 7 is detachable, the oil stains accumulated on the exhaust hood 7 can be cleaned, and during the cleaning process, water will not flow into the inside of the pot cover 1, avoiding the inside of the pot cover 1 from being wet, greatly increasing the stability and safety of the cooking utensils.

[0042] It should be noted that there are a plurality of exhaust holes 16 , and the plurality of exhaust holes 16 are arranged at intervals to ensure the exhaust efficiency of the exhaust hood 7 .

[0043] like Figures 1 to 4As shown, the side wall of the exhaust channel 6 has a first through hole 8. When the exhaust hood 7 is mounted on the bottom end of the exhaust channel 6, the first through hole 8 is connected to the exhaust channel 6; when the exhaust hood 7 is mounted on the top end of the exhaust channel 6, the exhaust hood 7 blocks the first through hole 8. The first through hole 8 in the exhaust channel 6 is connected to the inside of the baking component 5, and is used to maintain the balance of the air pressure inside the baking component 5. After the inner cover 3 is mounted on the pot cover 1, the exhaust hood 7 is mounted on the top end of the exhaust channel 6 and blocks the first through hole 8 to prevent the humid gas in the pot body 2 from entering the inside of the baking component 5 through the first through hole 8 when the cooking utensil is performing conventional cooking, reducing the influence of the humid gas on the internal electrical components of the baking component 5, and increasing the stability and safety of the pot cover 1. When the inner cover 3 is not mounted on the pot cover 1, the exhaust hood 7 is mounted on the bottom end of the exhaust channel 6, and the cooking utensil can only perform baking cooking. At this time, the exhaust channel 6 is connected to the first through hole 8, so that the gas can flow into the inside of the baking component 5 through the exhaust channel 6 and the first through hole 8, ensuring the balance of the air pressure inside the baking component 5.

[0044] It should be noted that blocking means isolating the first through hole 8 to prevent the gas in the pot body 2 from flowing into the first through hole 8, and does not mean that the exhaust hood 7 must be attached to the first through hole 8. The exhaust hood 7 can be spaced apart from the first through hole 8, and it is sufficient to isolate the first through hole 8 from the gas flow channel.

[0045] like Figures 1 to 4 As shown, the cooking appliance further includes an air intake conduction structure 9, which has an air intake channel 10, and the first through hole 8 is connected to the internal space of the baking component 5 through the air intake conduction structure 9. The air intake conduction structure 9 can plan the flow direction of the gas to ensure that the gas only enters the internal space of the baking component 5, reduce the accumulation of gas in the cover body 4, avoid the moisture in the gas from affecting the internal electrical components of the cover body 4, increase the stability and safety of the cover body 4, and reduce safety hazards.

[0046] like Figure 1 and Figure 3 As shown, the cover 4 includes a reflector 17, and the reflector 17 has a receiving groove 18 with an opening facing downward. The baking assembly 5 includes a fan 19, a heating element 20 and a cover plate 21. The fan 19 is fixed on the reflector 17, and the fan blades of the fan 19 are located in the receiving groove 18. The heating element 20 is installed in the receiving groove 18 and is located below the fan 19. The cover plate 21 is arranged at the opening of the receiving groove 18, and the cover plate 21 has a plurality of mesh holes 22. When the heating element 20 is working, the air temperature around the heating element 20 will increase. The fan 19 works to blow the high-temperature gas toward the pot body 2, and the high-temperature gas is blown into the pot body 2 by the fan through the mesh holes 22 to bake the food in the pot body 2.

[0047] It should be noted that when baking and cooking, the gas enters the internal space of the baking component 5 through the exhaust channel 6, the first through hole 8 and the air intake conductive structure 9, and the gas becomes hot under the heat baking of the heating element 20. The fan 19 blows the hot air inside the baking component 5 to the cover plate 21, and the hot air enters the pot body 2 through the mesh 22. After the hot air circulates in the pot body 2, it is discharged from the exhaust channel 6 to the outside of the cooking utensil or enters the inside of the baking component 5 through the first through hole 8. This arrangement allows the hot gas in the pot body 2 to enter the inside of the baking component 5, reducing the heating time of the baking component 5 for the gas and increasing the baking efficiency of the cooking utensil.

[0048] like Figure 6 As shown, the side wall of the exhaust passage 6 has a second through hole 12. When the exhaust hood 7 is assembled at the bottom end of the exhaust passage 6, the exhaust hood 7 blocks the second through hole 12; when the exhaust hood 7 is assembled at the top end of the exhaust passage 6, the second through hole 12 is connected to the exhaust passage 6. Switching the position of the exhaust hood 7 can cause the second through hole 12 to be opened or closed, so that the second through hole 12 works or does not work.

[0049] It should be noted that blocking means isolating the second through hole 12 to prevent the gas in the pot body 2 from flowing into the second through hole 12. The exhaust hood 7 may be attached to the second through hole 12, but it may not be attached. The exhaust hood 7 may be spaced apart from the second through hole 12, and the second through hole 12 only needs to be isolated from the gas flow channel.

[0050] When the inner cover 3 is mounted on the pot cover 1, the exhaust hood 7 is mounted on the top of the exhaust passage 6 to make way for the inner cover 3. In other words, the first through hole 8 and the second through hole 12 are blocked in different cooking modes. So that the first through hole 8 and the second through hole 12 can achieve different functions. When the inner cover 3 is not mounted on the pot cover 1, the exhaust hood 7 is mounted on the bottom of the exhaust passage 6 to block the second through hole 12, so as to prevent the oily gas generated by the cooking utensils from flowing into the second through hole 12 during baking, thereby reducing the accumulation of oily gas in the second through hole 12.

[0051] like Figure 3 , Figure 4 and Figure 6As shown, the inner cover 3 has a pressure limiting valve assembly 13, which extends into the exhaust passage 6 and is located at the second through hole 12. The cover body 4 includes a push rod 11 extending from the second through hole 12, so that the push rod 11 can operate the pressure limiting valve assembly 13. When the exhaust hood 7 is installed at the top of the exhaust passage 6, the second through hole 12 is communicated with the exhaust passage 6, so that the push rod 11 can extend from the second through hole 12 to push the pressure limiting valve assembly 13, so that the internal gas of the cooking utensil is discharged through the pressure limiting valve assembly 13. When the exhaust hood 7 is assembled at the bottom end of the exhaust passage 6, the exhaust hood 7 blocks the second through hole 12 to hide the push rod 11 and prevent oil from accumulating on the push rod 11.

[0052] It should be noted that the cover body 4 also includes a push rod sealing ring, which is sleeved on the push rod 11 and abuts against the second through hole 12 to seal the gap between the push rod 11 and the second through hole 12, so as to prevent the high-temperature and humid gas from entering the interior of the cover body 4 when the cooking utensil is performing conventional cooking, thereby reducing the influence of the high-temperature and humid gas on the internal electrical components of the cover body 4 and increasing the stability and safety of the use of the cover body 4. In addition, during baking and cooking, the baking temperature is very high, and the push rod sealing ring is very easy to age in an environment at the baking temperature for a long time, resulting in air leakage between the push rod 11 and the second through hole 12, which poses a great safety hazard. The exhaust hood 7 blocks the second through hole 12 to isolate the push rod sealing ring, reduce the influence of the baking temperature on the push rod sealing ring, increase the stability and reliability of the push rod sealing ring, and increase the service life of the push rod sealing ring.

[0053] like Figure 5 , Figures 13 to 15 As shown, the outer wall of the exhaust hood 7 has a first limiting structure 14, and the side wall of the exhaust passage 6 has a second limiting structure 15 that cooperates with the first limiting structure 14. When the exhaust hood 7 is installed on the exhaust passage 6, the first limiting structure 14 and the second limiting structure 15 are engaged. The mutual cooperation between the first limiting structure 14 and the second limiting structure 15 enables the exhaust hood 7 to be stably installed in the exhaust passage 6, reduces the possibility of the exhaust hood 7 being separated from the exhaust passage 6, and increases the working stability of the exhaust hood 7. When the exhaust hood 7 is assembled at the bottom end of the exhaust passage 6, it is the limiting cooperation between the first limiting structure 14 and the second limiting structure 15 that prevents the exhaust hood 7 from falling.

[0054] like Figure 5 As shown, there are multiple first limiting structures 14, and the multiple first limiting structures 14 are arranged at equal intervals. The first limiting structures 14 are arranged one-to-one with the second limiting structures 15. This arrangement can ensure that the exhaust hood 7 is stably installed in the exhaust channel 6.

[0055] like Fig.14 and Fig.15As shown, the first limiting structure 14 is a limiting protrusion, and the second limiting structure 15 is a limiting groove; or the first limiting structure 14 is a limiting groove, and the second limiting structure 15 is a limiting protrusion. This arrangement facilitates the assembly between the first limiting structure 14 and the second limiting structure 15, and the first limiting structure 14 and the second limiting structure 15 are not easy to separate, so as to ensure the working stability of the exhaust hood 7.

[0056] Optionally, the limiting groove is an L-shaped groove, and the limiting protrusion is a limiting convex point, which can extend into the L-shaped groove. This screw-on clamping method makes it difficult for the limiting convex point to slide out of the L-shaped groove, thereby increasing the stability of the cooperation between the first limiting structure 14 and the second limiting structure 15, and preventing the exhaust hood 7 from slipping out of the exhaust channel 6.

[0057] like Fig.13 As shown, the pot cover 1 also includes a sealing structure 24, which is sleeved on the outer wall of the exhaust hood 7, and the sealing structure 24 is located above the first limiting structure 14, and the sealing structure 24 is clamped between the exhaust hood 7 and the exhaust channel 6 and seals the gap between the first limiting structure 14 and the second limiting structure 15. After the first limiting structure 14 and the second limiting structure 15 are assembled together, there is a certain gap between the first limiting structure 14 and the second limiting structure 15, so as to facilitate the assembly between the first limiting structure 14 and the second limiting structure 15. The sealing structure 24 is clamped between the outer wall of the exhaust hood 7 and the exhaust channel 6 to seal the gap between the first limiting structure 14 and the second limiting structure 15, so as to reduce the gas from flowing into the first through hole 8 or the second through hole 12.

[0058] It should be noted that the sealing structure 24 is located above the first limiting structure 14 when the exhaust hood 7 is placed forward (the state when the exhaust hood 7 is assembled on the top of the exhaust passage 6). Fig.13 In the embodiment, the sealing structure 24 is located below the first limiting structure 14)

[0059] like Figure 2 and Figure 4 As shown, the exhaust hood 7 has a stop flange 26, which is located at one end of the exhaust hood 7. When the exhaust hood 7 is assembled at the top of the exhaust passage 6, the stop flange 26 overlaps the surface cover 41 of the cover body 4 and forms a seal with the surface cover 41; when the exhaust hood 7 is assembled at the bottom of the exhaust passage 6, the stop flange 26 abuts against the reflector 17 of the cover body 4 and forms a seal with the reflector 17. The setting of the stop flange 26 can form a seal on part of the structure of the exhaust passage 6 to reduce the impact of gas on the exhaust passage 6.

[0060] like Figure 4As shown, when the exhaust hood 7 is assembled on the top of the exhaust passage 6, the stop flange 26 and the surface cover 41 are stopped and sealed to prevent gas from entering the first through hole 8 from the gap between the surface cover 41 and the exhaust passage 6, and at this time, the sealing structure 24 is located below the first through hole 8 to seal the gap between the first limiting structure 14 and the second limiting structure 15 to prevent gas in the pot body 2 from entering the first through hole 8. The first through hole 8 is located between the sealing structure 24 and the stop flange 26, so that the exhaust hood 7 blocks the first through hole 8.

[0061] like Figure 2 As shown, when the exhaust hood 7 is assembled at the bottom of the exhaust passage 6, the stop flange 26 and the reflector hood 17 are stopped and sealed to prevent the gas in the pot body from entering the second through hole 12 through the gap between the reflector hood 17 and the exhaust passage 6, and at this time, the sealing structure 24 is located above the second through hole 12 to seal the gap between the first limiting structure 14 and the second limiting structure 15 to prevent the gas discharged from the outside of the cooking utensil or the pot body 2 from entering the second through hole 12. The second through hole 12 is located between the sealing structure 24 and the stop flange 26, so that the exhaust hood 7 blocks the second through hole 12.

[0062] like Figure 2 and Figure 4 As shown, the pot cover 1 further includes a sealing structure 24, which is sleeved on the outer wall of the exhaust hood 7, the outer wall of the exhaust hood 7 has a first snap-fitting protrusion 23, the inner wall of the exhaust passage 6 has a second snap-fitting protrusion 25 matched with the sealing structure 24, and the sealing structure 24 is snap-fitted between the first snap-fitting protrusion 23 and the second snap-fitting protrusion 25. The sealing structure 24 is snap-fitted between the first snap-fitting protrusion 23 and the second snap-fitting protrusion 25 to prevent the sealing structure 24 from falling off, and to ensure that the sealing structure 24 can stably seal the gap between the exhaust hood 7 and the exhaust passage 6.

[0063] like Figure 1 and Figure 3 As shown, the baking component 5 is eccentrically installed below the cover body 4, and the baking component 5 is arranged to avoid the exhaust channel 6, so that the hot air generated by the baking component 5 circulates in the pot body 2 before being discharged through the exhaust channel 6, so as to increase the utilization rate of the hot air generated at the baking component 5 and the baking efficiency of the baking component 5.

[0064] Optionally, the bottom surface of the baking assembly 5 is flush with the bottom end of the exhaust channel 6. This arrangement facilitates the inner cover 3 to be installed on the pot cover 1 to ensure the stability of the pot cover 1 during operation.

[0065] It should be noted that there may be many ways for the exhaust hood 7 to block the first through hole 8 or the second through hole 12 , and the exhaust hood 7 blocking the first through hole 8 is taken as an example for description.

[0066] In the first case, the exhaust hood 7 is blocked at the first through hole 8 by the sealing structure 24 to seal the first through hole 8 .

[0067] In the second case, the outer wall of the exhaust hood 7 directly contacts the first through hole 8 to seal the first through hole 8 .

[0068] In the third case, at the top of the exhaust hood 7, the stop flange 26 and the cover 41 are abutted and sealed, and at the bottom of the exhaust hood 7, the sealing structure 24 is clamped between the first clamping flange 23 and the second clamping flange 25 to limit the first through hole 8 in the gap between the stop flange 26 and the sealing structure 24, and the first through hole 8 is spaced apart from the outer wall of the exhaust hood 7. In this case, the gas cannot enter the first through hole 8 either.

The stop cylinder 40 extends upward from the liner 43.

[0072] like Figure 4 As shown, when the exhaust cover 7 is assembled on the top of the exhaust passage 6, the top surface of the second clamping protrusion 25 abuts against the sealing structure 24. Figure 2 In the specific embodiment shown, when the exhaust cover 7 is assembled at the bottom end of the exhaust passage 6 , the bottom surface of the second engaging protrusion 25 abuts against the sealing structure 24 .
