Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] A range hood is a kitchen appliance installed above the stove to purify the kitchen environment and remove cooking fumes from the kitchen. To enhance its aesthetics, range hoods are designed to open and close automatically. When the user turns off the range hood, the control panel is closed, concealing grease on the air intake surface. When the user turns on the range hood, the control panel opens, allowing the air intake to draw in cooking fumes.

[0003] For most range hoods, the movable panel is typically a single, large piece. The back of the panel also houses the display components and switch box, resulting in a significant load. To prevent cooking fumes from affecting the drive mechanism, the drive mechanism is located on one side of the movable panel, with the other side passively opening and closing. However, this structure can lead to unstable movement of the movable panel, and for larger panels, the movement of the left and right sides can be asynchronous. This results in uneven gaps between the left and right sides when closed, affecting the aesthetics. Utility Model Content

[0004] To address the aforementioned technical issues, this application provides a range hood that improves the consistency of movement on both sides of the movable panel, ensuring stable movement and enhancing aesthetics and user experience.

[0005] This application provides a range hood, including: The housing and panel, the housing having a smoke chamber; A smoke guiding assembly is connected to the housing and located within the smoke chamber, and the smoke guiding assembly has a receiving cavity; A first smoke collection hood is connected to the box body, and the first smoke collection hood has a through hole and a first smoke inlet communicating with the smoke chamber; An active component includes a drive structure and a drive rod connected to each other. The drive structure is disposed in the accommodating cavity, and the drive rod passes through the through hole and is connected to the middle position of the panel in the left-right direction, for driving the panel to rotate relative to the housing to open or close the first smoke inlet. The driven components are provided on both the left and right sides of the panel. The driven components are rotatably connected to the housing or the first smoke hood and are configured to rotate synchronously with the panel.

[0006] The range hood provided in this embodiment, by setting up an active component, a driven component, and a smoke guiding component, provides a cavity for the drive structure of the active component and guides the oil fumes, reducing the impact of oil fumes on the drive structure. The drive rod of the active component passes through the through hole on the first smoke collection hood and connects to the panel. At the same time, the driven components on the left and right sides of the panel rotate synchronously with the panel when it moves. This provides support in the middle and on the left and right sides of the panel, enabling the panel to move stably and improving the consistency of the movement of the left and right sides of the panel, thus improving the problem of inconsistent gaps on the left and right sides of the panel after it is closed.

[0007] In some embodiments, the smoke guiding assembly includes two guide plates spaced apart in the left-right direction of the panel, and the driving structure is disposed between the two guide plates; The first smoke collection hood has a baffle plate with the through hole, and the baffle plate is connected to the two guide plates.

[0008] The drive structure is located between two guide plates, and a baffle is provided on the first smoke collection hood. The baffle blocks the gap between the two guide plates, thereby forming a relatively closed cavity. The baffle also blocks the oil fumes on the front side, thus reducing the amount of oil fumes entering the cavity.

[0009] In some embodiments, the guide plate includes a first plate and a second plate connected to each other, and in the left-right direction of the panel, the second plate is inclined relative to the first plate towards the other first plate. The second plates of the two guide vanes are connected, and the second plates are located above the drive structure.

[0010] The second plate serves two purposes: firstly, it guides the fumes, causing them to converge towards the center of the fume guide assembly and directly face the fan, allowing for rapid exhaust under its influence. Secondly, the two plates are connected and positioned above the drive structure, shielding it from oil dripping from the fan and further protecting the drive structure from fumes.

[0011] In some embodiments, the driven component is disposed above the first smoking port; And / or, the range hood further includes a smoke baffle, and two smoke baffles are provided. The two smoke baffles are respectively located on both sides of the first smoke inlet in the left-right direction of the panel. The smoke baffles are connected to the housing and the first smoke collection hood. The driven component is located on the outside of the smoke baffle.

[0012] By placing the driven component above the first smoke inlet, when the range hood is working, the fumes enter the smoke chamber through the first smoke inlet, which reduces the impact of the fumes on the driven component. In other words, it avoids the accumulation of too much oil on the driven component, which would affect its operation.

[0013] Two smoke baffles are located on the left and right sides of the first smoke inlet, forming a fume channel between them. The driven component is placed on the outside of the smoke baffles, thus preventing the fumes entering from the first smoke inlet from affecting the driven component, which reduces the accumulation of grease on the driven component.

[0014] In addition, the aforementioned smoke baffle not only blocks the fumes from the driven components, but also forms a fume channel with the smoke guide components, reducing the flow area and increasing the flow rate of the fumes, so that the fumes can be discharged quickly.

[0015] In some embodiments, the driven component includes a rotating arm, one end of which is connected to the panel and the other end is rotatably connected to the first smoke hood or the housing, wherein the first smoke hood has a swing arm hole through which the rotating arm passes.

[0016] The rotating arm rotates synchronously with the panel through the swing arm hole. When the panel is closed, the swing arm rotates towards the back of the first smoke hood through the swing arm hole. This allows the panel to be as close as possible to the first smoke hood to seal the first smoke inlet, reducing the gap between the panel and the first smoke hood when closed, thereby improving aesthetics and reducing the accumulation of dust in the gap.

[0017] In some embodiments, the driven component includes a rotating arm, one end of which is rotatably connected to the housing or the first smoke hood, and the other end is fixedly connected to the panel; The front end of the top plate of the box is set as an arc-shaped structure, and the panel rotates around the arc-shaped structure.

[0018] By setting the front end of the top plate to an arc shape, the gap between the arc shape and the panel can be minimized, thus avoiding friction between the panel and the arc shape. Furthermore, when the panel opens the first smoke inlet, the gap between the panel and the top plate is smaller, reducing or even preventing fumes from escaping from the top of the panel.

[0019] In some embodiments, the range hood further includes a second smoke collection hood, which has a second smoke inlet that communicates with the smoke chamber and is normally open; The second smoke hood is located below the first smoke hood.

[0020] By setting two smoke collection hoods, the first smoke inlet of the first smoke collection hood can be opened or closed by the panel, while the second smoke inlet of the second smoke collection hood remains open. In this way, the range hood can draw in oil fumes through the second smoke inlet when the panel is not opened, thus eliminating the need to start the panel.

[0021] In some embodiments, the first smoke hood is recessed inward to form a smoke-containing cavity, the first smoke hood has an oil guide plate that is inclined relative to the vertical direction, the oil guide plate constitutes the lower side plate of the smoke-containing cavity, the first smoke inlet is provided on the bottom plate of the smoke-containing cavity, and the lower edge of the oil guide plate is located inside the second smoke hood.

[0022] The smoke-collecting chamber is designed to hold oil fumes, while the oil guide plate allows condensed oil to flow down. Since the lower edge of the oil guide plate is located inside the second smoke hood, the oil can flow through the gap between the first and second smoke hoods to the back of the second smoke hood, preventing oil from flowing onto the gas stove below.

[0023] In some embodiments, the range hood further includes a decorative element disposed at the upper end of the second smoke collection hood.

[0024] By adding decorative elements, not only can the upper part of the second smoke hood and the lower edge of the oil guide plate be covered, improving the aesthetics, but the second smoke hood can also be raised, which helps to block the oil stains on the oil guide plate.

[0025] In some embodiments, an oil collection groove is formed at the lower end of the second smoke hood, and an oil leakage groove is provided on the back side of the first smoke hood, with the oil collection groove located below the oil leakage groove. The range hood also includes an oil cup, which is connected to the housing and located below the oil collection trough. The second smoke collection hood has an oil leakage hole at the oil collection trough.

[0026] The oil stains on the back of the first smoke hood collect into the oil drain trough and flow into the oil collection trough. The oil stains on the back of the second smoke hood collect into the oil collection trough. The oil stains in the oil collection trough then flow into the oil cup through the oil drain hole, thus achieving oil collection. Attached Figure Description

[0031] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0033] In related technologies, the movable panel of a range hood is generally a single piece of panel with a large area. The back of the movable panel also houses display components, a switch box, etc., resulting in a significant load. To prevent cooking fumes from affecting the drive structure, the drive structure is usually located on one side of the movable panel, with the other side passively opening and closing. This makes the movement of the movable panel unstable, prone to wobbling, and the left and right sides are easily out of sync. This results in inconsistent gaps between the left and right sides when closed, affecting the aesthetics.

[0034] Based on this, this application provides a range hood that improves the stability of the panel's movement by placing an active component in the center of the panel and driven components on both the left and right sides. This ensures synchronization between the left and right sides, preventing inconsistent gaps. Furthermore, the smoke-guiding component protects the active component by placing it within the accommodating cavity, reducing the impact of cooking fumes on it.

[0035] The following reference Figures 1 to 17 The range hood provided in the embodiments of this application will be described in detail.

[0036] Reference Figures 1 to 17 As shown, some embodiments of this application provide a range hood, which includes a smoke collection box 100 and a fan box 200. An oil fume channel is formed within the smoke collection box 100, connecting to the inner cavity of the fan box 200. A fan is installed inside the fan box 200. The smoke collection box 100, under the action of the fan within the fan box 200, functions to collect smoke. Oil fumes enter the oil fume channel and are discharged through a pipe from the fan box 200.

[0037] Reference Figure 1 The range hood's smoke collection box 100 includes a box body 1 and a panel 2.

[0038] The housing 1 has a smoke chamber 1a. The panel 2 can open or close the housing. When the range hood is working, the panel 2 is open, and the cooking fumes can enter the smoke chamber 1a and be discharged under the action of the fan. When the range hood is not working, the panel 2 is closed, which improves the aesthetics.

[0039] Reference Figures 4 to 7 The range hood also includes a first smoke collection hood 3, which is connected to the housing 1. The first smoke collection hood 3 has a through hole 311a and a first smoke inlet 31a that communicates with the smoke chamber 1a. In this way, the fumes enter the smoke chamber 1a through the first smoke inlet 31a, and the panel 2 can open or close the first smoke inlet 31a.

[0040] Reference Figures 3 to 7 The range hood also includes a smoke guiding assembly 4 and an active assembly 5. The smoke guiding assembly 4 is connected to the housing 1 and located within the smoke chamber 1a, and has a receiving cavity. The active assembly 5 includes a connected drive structure 51 and a drive rod 52. The drive structure 51 is disposed within the receiving cavity, and the drive rod 52 passes through a through hole 311a and is connected to the middle position of the panel 2 in the left-right direction, for driving the panel 2 to rotate relative to the housing 1 to open or close the first smoke inlet 31a.

[0041] Understandably, the drive structure 51 of the active component 5 drives the panel 2 to rotate relative to the housing 1 via the drive rod 52. Since the drive structure 51 is located inside the accommodating cavity, the impact of oil fumes on it can be reduced. Furthermore, the guiding effect of the smoke guide component 4 further reduces the impact of oil fumes on the drive structure 51.

[0042] Reference Figures 4 to 6 The range hood also includes a driven component 6. Both sides of the panel 2 are provided with driven components 6. The driven components 6 are rotatably connected to the housing 1 or the first smoke collection hood 3 and are configured to rotate synchronously with the panel 2.

[0043] Understandably, by setting the driven component 6, the driven component 6 can provide support for the panel 2 as the active component 5 drives the panel 2 to rotate relative to the housing 1. This improves the stability of the panel 2 during movement and enhances the consistency of movement on the left and right sides of the panel 2.

[0044] For example, the driven component 6 may be configured to include a rotating arm 61, one end of which is rotatably connected to the housing 1 or the first smoke hood 3, and the other end is fixedly connected to the panel 2. This not only provides support when the panel 2 moves, but also limits the rotation of the panel 2, so that the panel 2 can make a circular motion around the end of the rotating arm 61 connected to the housing 1 or the first smoke hood 3.

[0045] The range hood provided in this embodiment, by setting up an active component 5, a driven component 6, and a smoke guiding component 4, provides a cavity for the drive structure 51 of the active component 5 and guides the oil fumes, reducing the impact of oil fumes on the drive structure 51. The drive rod 52 of the active component 5 passes through the through hole 311a on the first smoke collection hood 3 and connects to the panel 2. At the same time, the driven components 6 on the left and right sides of the panel 2 rotate synchronously with the panel 2 when the panel 2 moves. In this way, support is provided in the middle and on the left and right sides of the panel 2, so that the panel 2 can move stably and improve the consistency of the movement of the left and right sides of the panel 2, thereby improving the problem of inconsistent gaps on the left and right sides of the panel 2 after it is closed.

[0046] In addition, the smoke guiding component 4 occupies part of the space in the smoke chamber 1a. As a result, the flow rate of the oil fumes increases under the action of the fan, so that the oil fumes can be discharged quickly.

[0047] In some embodiments, refer to Figures 4 to 7 The aforementioned driven component 6 is disposed above the first smoke inlet 31a.

[0048] Understandably, by placing the driven component 6 above the first smoke inlet 31a, when the range hood is working, the fumes enter the smoke chamber 1a through the first smoke inlet 31a, which reduces the impact of the fumes on the driven component 6, thus preventing the accumulation of too much oil on the driven component 6 and affecting its operation.

[0049] For example, the driven component 6 includes a rotating arm 61, one end of which is connected to the panel 2 and the other end is rotatably connected to the first smoke hood 3. The first smoke hood 3 has a swing arm hole 34a through which the rotating arm 61 passes.

[0050] Understandably, the rotating arm 61 rotates synchronously with the panel 2 through the swing arm hole 34a. Thus, when the panel 2 is closed, the rotating arm 61 rotates towards the back of the first smoke hood 3 through the swing arm hole 34a. This allows the panel 2 to be as close as possible to the first smoke hood 3 and close the first smoke inlet 31a, reducing the gap between the panel 2 and the first smoke hood 3 when closed, thereby improving aesthetics and reducing the accumulation of dust in the gap.

[0051] Furthermore, a fixing member 35 is provided on the back side of the first smoke hood 3, and the aforementioned rotating arm 61 is rotatably connected to the fixing member 35. In this way, the fixing member 35 enhances the strength of the connection between the rotating arm 61 and the first smoke hood 3, and improves the stability of the rotating arm 61 when rotating.

[0052] In some embodiments, refer to Figures 4 to 6 In some embodiments, the range hood further includes two smoke baffles 12, which are located on opposite sides of the first smoke inlet 31a in the left-right direction of the panel 2. The smoke baffles 12 are connected to the housing 1 and the first smoke collection hood 3. The driven component 6 is located outside the smoke baffles 12. The left-right direction of the panel 2 is as follows... Figure 5 The X direction is shown in the diagram.

[0053] Understandably, the two smoke baffles 12 are located on the left and right sides of the first smoke inlet 31a, thus forming a fume channel between the two smoke baffles 12. The driven component 6 is set on the outside of the smoke baffles 12, so the driven component 6 is located outside the fume channel. This can prevent the fumes entering from the first smoke inlet 31a from affecting the driven component 6, that is, reduce the accumulation of oil stains on the driven component 6.

[0054] In addition, the above-mentioned smoke baffle 12 not only blocks the oil fumes for the driven component 6, but also forms an oil fume channel with the smoke guide component 4, reducing the flow area and increasing the flow rate of oil fumes, so that the oil fumes can be discharged quickly.

[0055] In some embodiments, refer to Figure 3 and Figure 8The driven component 6 includes a rotating arm 61, one end of which is rotatably connected to the first smoke hood 3 or the housing 1, and the other end is connected to the panel 2. The front end of the top plate 11 of the housing 1 is configured as an arc-shaped structure 111, and the panel 2 rotates around the arc-shaped structure 111.

[0056] Understandably, due to the configuration of the rotating arm 61, the rotation of the rotating arm 61 is a circular motion around the connection point with the housing 1 or the first smoke collection hood 3, so that the panel 2 also rotates around an axis. At this time, by setting the front end of the top plate 11 as an arc-shaped structure 111, the gap L between the arc-shaped structure 111 and the panel 2 can be minimized, thus avoiding friction between the panel 2 and the arc-shaped structure 111. Furthermore, when the panel 2 opens the first smoke inlet 31a, the gap L between the panel 2 and the top plate 11 is smaller, reducing or even preventing the oil fumes from escaping from the top of the panel 2.

[0057] For example, the aforementioned rotating arm 61 is rotatably connected to the first smoke collection hood 3. A fixing member 35 is provided on the back side of the first smoke collection hood 3, and the aforementioned rotating arm 61 is rotatably connected to the fixing member 35. In this way, the fixing member 35 enhances the strength of the connection between the rotating arm 61 and the first smoke collection hood 3, and improves the stability of the rotating arm 61 when rotating.

[0058] In some embodiments, refer to Figure 5 , Figure 9 and Figure 10 The smoke guiding assembly 4 includes two guide plates 41 spaced apart in the left and right direction of the panel 2, and the driving structure 51 is disposed between the two guide plates 41.

[0059] The first smoke hood 3 has a baffle 311, and the baffle 311 has a through hole 311a. The baffle 311 is connected to two guide plates 41.

[0060] Understandably, the drive structure 51 is located between the two guide plates 41, and the first smoke collection hood 3 is provided with a baffle 311. In this way, the baffle 311 is used to block the gap between the two guide plates 41, thereby forming a relatively closed cavity. The baffle 311 blocks the oil fumes on the front side, thus reducing the amount of oil fumes entering the accommodating cavity.

[0061] It should be noted that the baffle 311 divides the first smoke inlet 31a of the first smoke hood 3 into two smoke inlets. The smoke guiding assembly 4 divides the smoke chamber 1a of the housing 1 into two smoke distribution chambers. Thus, the two smoke inlets correspond to the two smoke distribution chambers, and the two smoke inlets correspond to the two burners of the gas stove. This increases the suction power of the range hood to the fumes generated by the cookware on each burner when the range hood is working, thereby achieving rapid smoke exhaust.

[0062] Furthermore, referring to Figure 9 and Figure 10 The aforementioned guide plate 41 includes a first plate 411 and a second plate 412 connected together. In the left-right direction of the panel 2, the second plate 412 is inclined relative to the first plate 411 towards the other first plate 411. The second plates 412 of the two guide plates 41 are connected, and the second plate 412 is located above the drive structure 51. The left-right direction of the panel 2 is as follows... Figure 10 The X direction is shown in the diagram.

[0063] Understandably, the second plate 412 serves two purposes. First, it guides the fumes, causing them to converge towards the center of the smoke guide assembly 4 and face the fan as directly as possible, allowing them to be quickly expelled under the fan's influence. Second, the two second plates 412 are connected and positioned above the drive structure 51, shielding it from oil dripping from the fan onto the drive structure 51, thus further protecting the drive structure 51 from fumes.

[0064] In some embodiments, refer to Figure 10 The range hood also includes a first filter 9, which is installed on the first smoke collection hood 3 and located at the first smoke inlet 31a. The first filter 9 is provided with a plurality of through first strip-shaped holes 91 so that the oil fumes can enter the smoke chamber through the first strip-shaped holes 91.

[0065] The first strip-shaped hole 91 is provided with a flange circumferentially around one side of the smoke chamber 1a. This flange is circumferentially surrounding the first strip-shaped hole 91 and can prevent oil from flowing out of the first strip-shaped hole 91 to the outside of the first smoke collection hood 3. In addition, the flange creates an oil guiding channel between two adjacent first strip-shaped holes 91, which facilitates the flow of oil into the oil cup 10 of the range hood.

[0066] In addition, refer to Figures 11 to 14 To collect the oil flowing down the first filter screen 9 and prevent it from spreading, a baffle 82 is connected to the back side of the first smoke hood 3. An oil drain groove 82a is formed between the baffle 82 and the first smoke hood 3. The lower end of the first filter screen 9 extends into the oil drain groove 82a and is supported by the baffle 82. An oil hole 821 is provided on the baffle 82. In this way, the oil on the back side of the first filter screen 9 flows into the oil drain groove 82a and flows downward through the oil hole 821 and finally into the oil cup 10 of the range hood.

[0067] Specifically, the aforementioned range hood has two first filters 9. This is because the first smoke inlet 31a is divided into two smoke inlets by a baffle 311 of the first smoke collection hood 3, and each of the two smoke inlets is equipped with a first filter 9. The baffle 311 is used to connect the smoke guiding assembly 4.

[0068] In some embodiments, refer to Figures 15 to 17The range hood also includes a second smoke collection hood 7, which has a second smoke inlet that is open and communicates with the smoke chamber. The second smoke collection hood 7 is located below the first smoke collection hood 3.

[0069] Understandably, by setting two smoke collection hoods, the first smoke inlet 31a of the first smoke collection hood 3 can be opened or closed by the panel 2, while the second smoke inlet on the second smoke collection hood 7 remains open. In this way, when the panel 2 is not opened, the range hood can draw in oil fumes through the second smoke inlet, thus eliminating the need to start the panel 2.

[0070] Of course, if there is less oil smoke, the oil smoke can be drawn out through the second smoke inlet. When there is more oil smoke, the control panel opens the first smoke inlet 31a, and the first smoke inlet 31a and the second smoke inlet draw out the oil smoke at the same time.

[0071] It should be noted that the lower end of the first smoke hood 3 is located inside the second smoke hood 7, thus preventing the oil stains flowing down from the back of the first smoke hood 3 from flowing out of the range hood.

[0072] In addition, the second smoke hood 7 has multiple through-holes 71a to allow fumes to enter the smoke chamber 1a. At this time, the multiple through-holes 71a constitute the second smoke inlet of the second smoke hood 7.

[0073] Furthermore, referring to Figure 15 The first smoke hood 3 is recessed inward to form a smoke-containing cavity 3a. The first smoke hood 3 has an oil guide plate that is inclined relative to the vertical direction. The oil guide plate forms the lower side plate 32 of the smoke-containing cavity 3a. A first smoke inlet 31a is opened on the bottom plate 31 of the smoke-containing cavity 3a. The lower edge of the oil guide plate is located inside the second smoke hood 7. Here, the lower edge of the oil guide plate refers to the edge of the lower end of the oil guide plate in the vertical direction.

[0074] Understandably, the smoke-containing chamber 3a can accommodate oil fumes, while the oil guide plate allows condensed oil to flow down. Since the lower edge of the oil guide plate is located inside the second smoke hood 7, the oil can flow through the gap between the first smoke hood 3 and the second smoke hood 7 to the back of the second smoke hood 7, preventing oil from flowing onto the gas stove below.

[0075] It should be noted that, in order for the grease flowing down from the gaps between the first smoke hood 3 and the second smoke hood 7 to enter the oil cup 10 of the range hood, the second smoke hood 7 is recessed to form a smoke-collecting chamber. At this time, the second smoke hood 7 forms a protrusion within the smoke chamber of the housing 1, and an oil guiding channel is formed between the side wall of the protrusion and the side wall of the housing 1. The grease flowing down from the gaps between the first smoke hood 3 and the second smoke hood 7 flows into the oil cup 10 through the oil guiding channel. The oil guiding channel is as follows: Figure 16 As shown by the arrow in the image.

[0076] Furthermore, the first smoke hood 3 also has a connecting plate 33, which is connected to the second smoke hood 7 and to the lower edge of the oil guide plate. The connecting plate 33 and the oil guide plate are integrally formed, meaning the first smoke hood 3 is a single structural component, reducing the number of parts and assembly steps. Thus, the upper end of the second smoke hood 7 is connected to the first smoke hood 3, while the lower end of the second smoke hood 7 is connected to the housing 1.

[0077] In addition, a swing arm hole 34a is provided on the upper side plate 34 of the smoke-containing cavity 3a.

[0078] Furthermore, the above-mentioned range hood also includes a decorative component 81, which is disposed at the upper end of the second smoke collection hood 7.

[0079] Understandably, by setting the decorative piece 81, not only can the upper end of the second smoke hood 7 and the lower edge of the oil guide plate be covered to improve the aesthetics, but it can also raise the second smoke hood 7, which is beneficial for blocking the oil stains on the oil guide plate.

[0080] Furthermore, referring to Figure 17 The lower end of the second smoke hood 7 has an oil collection groove 72a, and the back side of the first smoke hood 3 has an oil drain groove 82a, with the oil collection groove 72a located below the oil drain groove 82a. The range hood also includes an oil cup 10, which is connected to the housing 1 and located below the oil collection groove 72a. The second smoke hood 7 has an oil drain hole 721 at the oil collection groove 72a.

[0081] Understandably, the oil on the back of the first fume hood 3 is collected into the oil drain 82a and flows into the oil collection trough 72a, while the oil on the back of the second fume hood 7 is collected into the oil collection trough 72a. The oil in the oil collection trough 72a then flows into the oil cup 10 through the oil drain hole 721, thus achieving the collection of oil.

[0082] For example, refer to Figures 15 to 17 The first smoke collection hood 3 is recessed inward to form a smoke-containing cavity 3a. A first smoke inlet 31a is provided on the bottom plate 31 of the smoke-containing cavity 3a, and an oil leakage groove 82a is provided on the back side of the bottom plate 31. The lower side plate 32 of the smoke-containing cavity 3a is inclined relative to the vertical direction.

[0083] The second smoke hood 7 includes a first part 71 and a second part 72. The first part 71 has a second smoke inlet, and the second part 72 has the aforementioned oil collection groove 72a. The aforementioned oil leakage groove 82a is located directly above the second part 72, so that the oil in the oil leakage groove 82a can drip into the oil collection groove 72a. The first part 71 is connected to the first smoke hood 3, and the second part 72 is connected to the housing 1, thus fixing the second smoke hood 7.

[0084] The first part 71 is recessed to form a smoke collection chamber, thus forming an oil guiding channel between the first part 71 and the side wall of the box 1. The oil flowing down from the gap between the first smoke hood 3 and the second smoke hood 7 flows through the oil guiding channel to the oil collection tank 72a, and finally flows into the oil cup 10.
