Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to an oil guiding structure and a range hood. Background Technology

[0002] A range hood typically consists of a housing and a smoke guide plate. The housing has a smoke collection chamber, and the front panel of the housing has a smoke inlet connected to the smoke collection chamber. The smoke guide plate is rotatably mounted at the smoke inlet and can open or close the smoke inlet. When the range hood is working, the smoke guide plate can flip outward relative to the housing, opening the smoke inlet. Cooking fumes can enter the smoke inlet from the smoke collection area between the smoke guide plate and the housing. During this process, grease easily adheres to the inner surface of the smoke guide plate. When the smoke guide plate is closed, its inner surface adheres to the outer perimeter of the smoke inlet, causing the grease adhering to the inner surface of the smoke guide plate to accumulate between the outer perimeter of the smoke inlet and cannot be discharged. This severely affects the cleanliness of the range hood's surface and greatly increases the difficulty of cleaning. Furthermore, when temperatures drop, the grease can condense, and the condensed grease can stick the smoke guide plate and the outer perimeter of the smoke inlet together, preventing the smoke guide plate from opening again when the range hood is used, seriously affecting user experience. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an oil guiding structure for a range hood, which can effectively guide the grease on the inner surface of the smoke guide plate into the smoke collection chamber.

[0004] This utility model also proposes a range hood with the oil guiding structure of the above-mentioned range hood.

[0005] The oil guiding structure of the range hood according to an embodiment of the present invention includes: a housing having a smoke collection chamber and a smoke inlet communicating with the smoke collection chamber; a smoke guide plate rotatably mounted on the housing and capable of opening or closing the smoke inlet; a first oil guide member disposed on the inner wall of the smoke collection chamber and located below the smoke inlet, the first oil guide member having an extension portion extending upward to protrude from the smoke inlet, the extension portion having at least one forward-protruding abutment portion, the extension portion also having at least one first oil guide hole communicating with the smoke collection chamber, the horizontal height of the first oil guide hole being lower than the horizontal height of the abutment portion; when the smoke guide plate closes the smoke inlet, the smoke guide plate abuts against the abutment portion.

[0006] The oil guiding structure of the range hood according to the embodiment of this utility model has at least the following beneficial effects:

[0007] In the oil guiding structure of the range hood in this embodiment of the utility model, by providing a first oil guiding member, the extension extends upward to protrude from the smoke inlet, so that the extension forms the lower edge of the smoke inlet. When the smoke inlet is closed, the smoke guide plate can abut against the abutting part of the first oil guiding member, so that the smoke guide plate and the extension are spaced apart, and thus the smoke guide plate and the outer periphery of the smoke inlet are spaced apart. As a result, the grease adsorbed on the inner surface of the smoke guide plate can flow between the smoke guide plate and the extension, and can flow downward along the gap between the smoke guide plate and the extension to the first oil guiding hole, and finally flow into the smoke collection chamber from the first oil guiding hole. This can prevent grease from accumulating between the smoke guide plate and the outer periphery of the smoke inlet, which not only helps to reduce the difficulty of cleaning the range hood, but also reduces the risk that the smoke guide plate and the outer periphery of the smoke inlet will stick together due to grease condensation and cannot be opened normally, making it convenient for users.

[0011] According to some embodiments of the present invention, a second oil guide is further provided in the smoke collection chamber. The second oil guide is disposed on the inner surface of the front plate and located below the first oil guide. The second oil guide is provided with a second oil guide groove arranged in a V-shape and a third oil guide groove located below the second oil guide groove. The third oil guide groove is connected to the lower end of the second oil guide groove, and the third oil guide groove extends from top to bottom toward the bottom of the smoke collection chamber.

[0012] According to some embodiments of the present invention, the lower edge of the second oil guide member is bent from top to bottom and then backward to form a first oil guide plate, the lower edge of the first oil guide plate is bent from top to bottom and then backward to form a second oil guide plate, the second oil guide groove is formed by the first oil guide plate and the second oil guide plate surrounding each other, and the third oil guide groove is formed on the second oil guide plate.

[0013] According to some embodiments of the present invention, an oil mesh is installed inside the smoke inlet. The upper end of the oil mesh is magnetically connected to the upper edge of the smoke inlet via a magnetic suction component. The lower end of the oil mesh is provided with a plug-in portion, which is plugged into and connected to the first oil guide component.

[0014] According to some embodiments of the present invention, the first oil guide member is provided with a first oil guide groove, and the rear side wall of the first oil guide groove is provided with a slot corresponding to the plug-in part. The lower end of the oil mesh is located in the first oil guide groove and is arranged at intervals from the front side wall of the first oil guide groove. The plug-in part is inserted into the corresponding slot. The bottom wall of the first oil guide groove is also provided with a second oil guide hole, and the second oil guide hole is at least partially located on the front side of the oil mesh.

[0015] According to some embodiments of the present invention, the number of oil meshes is at least two, all of which are arranged side by side along the length of the smoke inlet, and adjacent oil meshes are connected or abutted against each other; the front surface of the oil mesh is provided with at least one forward-protruding limiting part, and when the smoke guide plate closes the smoke inlet, the limiting part abuts against the smoke guide plate.

[0016] The range hood according to the embodiments of the present invention is provided with the oil guiding structure of any of the above embodiments.

[0017] The range hood according to the embodiments of this utility model has at least the following beneficial effects:

[0018] In the range hood of this utility model embodiment, by setting the oil guiding structure of the range hood of any of the above embodiments, when the smoke guide plate closes the smoke inlet, the grease on the inner surface of the smoke guide plate can flow smoothly into the smoke collection chamber, without accumulating or condensing between the smoke guide plate and the outer periphery of the smoke inlet. This not only helps to reduce the difficulty of cleaning the range hood, but also reduces the risk that the smoke guide plate and the extension part will stick together due to grease condensation and cannot be opened normally, thereby greatly improving the user experience.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figures 1 to 5 This utility model provides an oil guiding structure for a range hood, including a housing 100, a smoke guide plate 200, and a first oil guiding component 300. The housing 100 has a smoke collection chamber 110 and a smoke inlet 120 communicating with the smoke collection chamber 110. The smoke guide plate 200 is rotatably mounted on the housing 100 and can open or close the smoke inlet 120. The first oil guiding component 300 is disposed on the inner wall of the smoke collection chamber 110 and located below the smoke inlet 120. The first oil guiding component 300 has an extension 310 extending upward to protrude from the smoke inlet 120. The extension 310 has at least one forward-protruding abutment portion 311 and at least one first oil guiding hole 312 communicating with the smoke collection chamber 110. The horizontal height of the first oil guiding hole 312 is lower than the horizontal height of the abutment portion 311. When the smoke guide plate 200 closes the smoke inlet 120, the smoke guide plate 200 abuts against the abutment portion 311.

[0040] In the oil guiding structure of the range hood in this embodiment of the utility model, by providing a first oil guiding member 300, the extension 310 extends upward to protrude from the smoke inlet 120, so that the extension 310 forms the lower edge of the smoke inlet 120. When the smoke guide plate 200 closes the smoke inlet 120, it can abut against the abutting part 311 of the first oil guiding member 300, so that the smoke guide plate 200 and the extension 310 are spaced apart, and thus the smoke guide plate 200 and the outer periphery of the smoke inlet 120 are spaced apart. As a result, the grease adsorbed on the inner surface of the smoke guide plate 200 can flow between the smoke guide plate 200 and the extension 310. Since the grease has a strong adsorption force, the grease can flow downward along the gap between the smoke guide plate 200 and the extension 310 to the first oil guiding hole 312 and flow into the smoke collection chamber 110 from the first oil guiding hole 312. Some grease can also flow from the inner surface of the oil guide plate. The oil flows to the contact portion 311, then along the contact portion 311 to the extension portion 310, and then flows downward along the gap between the smoke guide plate 200 and the extension portion 310 to the first oil guide hole 312. Finally, it flows into the smoke collection chamber 110 from the first oil guide hole 312. This can guide the grease on the inner surface of the smoke guide plate 200 to the inner wall of the smoke collection chamber 110, avoiding the accumulation of grease between the outer periphery of the smoke guide plate 200 and the smoke inlet 120. This not only helps to reduce the difficulty of cleaning the range hood, but also reduces the risk that the outer periphery of the smoke guide plate 200 and the smoke inlet 120 will stick together due to grease condensation and cannot be opened normally, making it convenient for users.

[0041] Reference Figures 1 to 5 In some embodiments, the number of abutting portions 311 is at least two, and all abutting portions 311 are arranged sequentially at intervals along the length direction of the smoke inlet 120, thereby enabling better abutment of the smoke guide plate 200 and preventing the smoke guide plate 200 from sticking together with the extension portion 310.

[0042] Reference Figures 1 to 5 In some embodiments, there are at least two first oil guide holes 312, and all the first oil guide holes 312 are arranged sequentially at intervals along the length of the smoke inlet 120. This allows the grease between the smoke guide plate 200 and the extension 310 to be quickly guided into the smoke collection chamber 110, further reducing the difficulty of cleaning the range hood and reducing the risk that the smoke guide plate 200 and the extension 310 will stick together due to grease condensation and cannot be opened normally, making it convenient for users to use.

[0043] Reference Figures 3 to 5 In some embodiments, the cross-sectional area of ​​the abutment portion 311 gradually decreases along the direction from back to front.

[0044] By adopting the above structure, the contact area between the contact part 311 and the oil guide plate can be effectively reduced, preventing grease from accumulating and condensing between the oil guide plate and the contact part 311. This allows the grease on the inner surface of the smoke guide plate 200 to be better guided to the inner wall of the smoke collection chamber 110, preventing grease from accumulating between the smoke guide plate 200 and the extension part 310. This not only helps reduce the difficulty of cleaning the range hood, but also reduces the risk that the smoke guide plate 200 and the contact part 311 of the extension part 310 will stick together due to grease condensation and cannot be opened normally, making it more convenient for users.

[0045] It is understandable that the outer surface of the abutment part 311 can be specifically set as a spherical surface, so that when the abutment part 311 abuts with the oil guide plate, the two are in point contact. This can reduce the contact area when the abutment part 311 abuts with the oil guide plate to a greater extent, and prevent grease from accumulating and condensing between the oil guide plate and the abutment part 311. This can better guide the grease on the inner surface of the smoke guide plate 200 to the inner wall of the smoke collection chamber 110, and prevent grease from accumulating between the smoke guide plate 200 and the extension part 310. This not only helps to reduce the difficulty of cleaning the range hood, but also reduces the risk that the smoke guide plate 200 and the abutment part 311 of the extension part 310 will stick together due to grease condensation and cannot be opened normally, making it convenient for users.

[0046] Reference Figures 3 to 5 In some embodiments, the periphery of the first oil guide hole 312 is provided with a flange 313 extending toward the interior of the smoke collection chamber 110.

[0047] In the above structure, the flange 313 extends from the periphery of the first oil guide hole 312 into the smoke collection chamber 110, that is, the flange 313 protrudes inward relative to the first oil guide member 300, thereby effectively preventing the grease adhering to the inner wall of the smoke collection chamber 110 from overflowing from the first oil guide hole 312, thereby effectively keeping the exterior of the box 100 clean and reducing the difficulty of cleaning the box 100.

[0048] Understandably, referring to Figures 3 to 5 The flange 313 can be formed by bending the periphery of the first oil guide hole 312 into the smoke collection cavity 110. This not only effectively prevents the grease adhering to the inner wall of the smoke collection cavity 110 from overflowing from the first oil guide hole 312, but also enhances the structural strength of the first oil guide 300.

[0049] Reference Figures 1 to 5In some embodiments, the housing 100 has a front plate 130 located below the smoke inlet 120, a first oil guide 300 disposed on the inner surface of the front plate 130 and extending upward to the upper side of the front plate 130, an abutment portion 311 located above the front plate 130, and the upper end of the front plate 130 partially obstructing the first oil guide hole 312; when the smoke guide plate 200 closes the smoke inlet 120, there is a gap between the lower edge of the smoke guide plate 200 and the upper edge of the front plate 130.

[0050] By adopting the above structure, the abutment portion 311 is disposed above the front plate 130, thereby effectively abutting the oil guide plate, so that there is a gap between the oil guide plate and the extension portion 310 for the downward flow of grease. By blocking part of the first oil guide hole 312 at the upper end of the front plate 130, the first oil guide hole 312 is at least partially located below the smoke guide plate 200, thereby allowing as much grease adsorbed on the inner surface of the smoke guide plate 200 as possible to flow downward into the first oil guide hole 312. At the same time, the grease adhering to the upper end of the front plate 130 can also flow into the first oil guide hole 312. Furthermore, when the smoke guide plate 200 closes the smoke inlet 120, there is a gap between the lower edge of the smoke guide plate 200 and the upper edge of the front plate 130. This prevents grease from accumulating or condensing between the smoke guide plate 200 and the front plate 130. The gap allows grease to flow to the first oil guide hole 312 and then from the first oil guide hole 312 into the smoke collection chamber 110. This not only helps reduce the difficulty of cleaning the range hood but also reduces the risk that the smoke guide plate 200 and the front plate 130 may stick together due to grease condensation and be unable to open properly, making it more convenient for users.

[0051] Understandably, both the smoke guide plate 200 and the front panel 130 can be made of tempered glass, allowing users to easily wipe away grease from the outer surface of the smoke guide plate 200 and the front panel 130 with a cleaning cloth, thus facilitating the cleaning of the range hood and making the range hood look cleaner and more aesthetically pleasing.

[0052] Reference Figures 1 to 8 In some embodiments, a second oil guide 400 is also provided in the smoke collection chamber 110. The second oil guide 400 is located on the inner surface of the front plate 130 and below the first oil guide 300. The second oil guide 400 is provided with a second oil guide groove 410 arranged in a V-shape and a third oil guide groove 420 located below the second oil guide groove 410. The third oil guide groove 420 is connected to the lower end of the second oil guide groove 410 and extends from top to bottom toward the bottom of the smoke collection chamber 110.

[0053] In the above structure, the second oil guide 400 can concentrate and guide the grease on the inner surface of the front plate 130 to the bottom of the smoke collection chamber 110. Specifically, the grease adsorbed on the inner surface of the front plate 130 can flow downward irregularly along the inner surface of the front plate 130. Through the second oil guide groove 410, the grease on the inner surface of the front plate 130 can flow downward into the second oil guide groove 410. The second oil guide groove 410 is arranged in a V-shape. The grease located in the second oil guide groove 410 can flow downward to the lower end of the second oil guide groove 410, and then flow into the third oil guide groove 420 and flow downward to the bottom of the smoke collection chamber 110.

[0054] Reference Figure 1 As shown in the figure, in some embodiments, the lower edge of the second oil guide 400 is bent from top to bottom and back to form a first oil guide plate 430, the lower edge of the first oil guide plate 430 is bent from top to bottom and back to form a second oil guide plate 440, the second oil guide groove 410 is formed by the first oil guide plate 430 and the second oil guide plate 440 surrounding each other, and the third oil guide groove 420 is formed on the second oil guide plate 440.

[0055] In the above structure, the lower edge of the second oil guide 400 is bent from top to bottom and then back to form the first oil guide plate 430, and the lower edge of the first oil guide plate 430 is bent from top to bottom and then back to form the second oil guide plate 440. This makes the second oil guide 400 form an integral bent structure, which greatly enhances the structural strength of the second oil guide 400. In addition, by adopting the above structure, it is convenient to open and process the second oil guide groove 410 and the third oil guide groove 420. That is, the second oil guide groove 410 is formed by the first oil guide plate 430 and the second oil guide plate 440 surrounding each other, and the third oil guide groove 420 is opened on the second oil guide plate 440. This not only makes the structure of the second oil guide 400 simpler, but also facilitates the production and processing of the second oil guide 400.

[0056] Reference Figure 1 As shown in the figure, in some embodiments, an oil mesh 500 is installed inside the smoke inlet 120. The upper end of the oil mesh 500 is magnetically connected to the upper edge of the smoke inlet 120 through a magnetic suction member 510. The lower end of the oil mesh 500 is provided with a plug-in part 520, which is plugged into and connected to the first oil guide member 300.

[0057] In the above structure, the upper end of the oil mesh 500 is magnetically connected to the upper edge of the smoke inlet 120, and the lower end of the oil mesh 500 is plugged into the first oil guide 300, i.e., the lower edge of the smoke inlet 120. This facilitates the disassembly and installation of the oil mesh 500, and consequently, the cleaning, maintenance, and replacement of the oil mesh 500. Furthermore, in this structure, the first oil guide 300 not only guides the grease on the inner surface of the smoke guide plate 200 to flow into the smoke collection chamber 110, but also serves to install and fix the oil mesh 500, greatly improving the utilization rate of the first oil guide 300.

[0058] Reference Figure 8 In some embodiments, two magnetic suction members 510 are provided between the upper end of the oil mesh 500 and the upper edge of the smoke inlet 120. The two magnetic suction members 510 are located at opposite ends of the oil mesh 500, thereby improving the installation stability of the oil mesh 500. Of course, the number of magnetic suction members 510 can be two, three, four, or more, and this utility model does not specifically limit this. When the number of magnetic suction members 510 is three or more, all magnetic suction members 510 can be arranged sequentially and at intervals along the upper edge of the oil mesh 500, thereby making the installation of the oil mesh 500 more secure and stable.

[0059] It is understood that the upper end of the oil mesh 500 is magnetically connected to the upper edge of the smoke inlet 120. Specifically, the magnetic component 510 is installed on the upper edge of the smoke inlet 120, and the upper end of the oil mesh 500 is provided with a magnetic surface that can cooperate with the magnetic component 510 for magnetic attraction. The magnetic component 510 can be installed on the upper edge of the smoke inlet 120 using a bolt structure or a snap-fit ​​structure, and the magnetic surface can be formed by bending the upper edge of the oil mesh 500 backwards. This facilitates the production and processing of the oil mesh 500. This utility model does not specifically limit the specific connection structure of the magnetic component 510 or the specific formation method of the magnetic surface. Of course, in order to achieve the magnetic connection between the oil mesh 500 and the upper edge of the smoke inlet 120, in addition to the above-described structure, the magnetic element 510 can also be installed on the oil mesh 500 with the magnetic surface located at the upper edge of the smoke inlet 120. Alternatively, two mutually magnetic elements 510 can be provided, with one magnetic element 510 installed on the oil mesh 500 and the other installed on the upper edge of the smoke inlet 120. This utility model does not specifically limit the magnetic connection between the oil mesh 500 and the upper edge of the smoke inlet 120.

[0060] Reference Figures 1 to 8In some embodiments, the first oil guide 300 is provided with a first oil guide groove 320, and the rear side wall of the first oil guide groove 320 is provided with a slot 321 corresponding to the insertion part 520. The lower end of the oil mesh 500 is located in the first oil guide groove 320 and is spaced apart from the front side wall of the first oil guide groove 320. The insertion part 520 is inserted into the corresponding slot 321. The bottom wall of the first oil guide groove 320 is also provided with a second oil guide hole 322, and the second oil guide hole 322 is at least partially located on the front side of the oil mesh 500.

[0061] By adopting the above structure, a first oil guide groove 320 is provided on the first oil guide member 300, and a slot 321 is opened on the rear side wall of the first oil guide groove 320. This allows the lower end of the oil mesh 500 to be directly inserted into the first oil guide groove 320 and the insertion part 520 to be inserted into the corresponding slot 321. When the oil mesh 500 is disassembled, it is only necessary to pull the oil mesh 500 outward so that the upper end of the oil mesh 500 is released from the magnetic attraction, and then lift the oil mesh 500 upward so that the insertion part 520 is released from the slot 32. The oil mesh 500 can be easily disassembled. The structure is simple and easy to disassemble and assemble. By setting a first oil guide groove 320 and opening a second oil guide hole 322 on the bottom wall of the first oil guide groove 320, the grease adhering to the outer surface of the oil mesh 500 can flow into the smoke collection chamber 110 through the filter holes (marked in the figure) on the oil mesh 500, and can also flow downward into the first oil guide groove 320, and then flow into the smoke collection chamber 110 from the second oil guide hole 322 at the bottom of the first oil guide groove 320. In the above structure, the first oil guide 300 not only guides the grease on the inner surface of the smoke guide plate 200 to flow into the smoke collection chamber 110, but also serves to install and fix the oil mesh 500 and guide the grease on the outer surface of the oil mesh 500 to flow into the smoke collection chamber 110, greatly improving the utilization rate of the first oil guide 300. Moreover, during production and processing, there is no need to process the insertion structure of the oil mesh 500 on the housing 100. Structures such as the slot 321 and the first oil guide groove 320 can be formed during the processing of the first oil guide 300, greatly improving the processing efficiency of the housing 100 and making the processing and production of the range hood more convenient.

[0062] Reference Figure 1 As shown in the figure, in some embodiments, the first oil guide groove 320 is a U-shaped groove formed by bending the free end of the extension 310 backwards, which makes the processing and forming of the first oil guide 300 more convenient and can improve the structural strength of the first oil guide 300.

[0063] In some embodiments, a backward-bent support plate (marked in the figure) is provided at the lower edge of the oil mesh 500. The support plate abuts against the bottom wall of the first oil guide groove 320. Multiple oil leakage holes are provided at the bend of the support plate. When the grease on the oil mesh 500 flows downward to the support plate, it can flow smoothly from the oil leakage holes into the first oil guide groove 320, and then flow along the first oil guide groove 320 to the second oil guide hole 322, and from the second oil guide hole 322 into the smoke collection chamber 110.

[0064] Reference Figures 1 to 8 In some embodiments, there are at least two oil meshes 500, all of which are arranged side by side along the length of the smoke inlet 120, and adjacent oil meshes 500 are connected or abutted against each other; the front surface of the oil mesh 500 is provided with at least one forward-protruding limiting part, which abuts against the smoke guide plate 200 when the smoke guide plate 200 closes the smoke inlet 120.

[0065] Compared to the traditional method of using a single piece of oil filter 500, this embodiment of the invention employs a structure of at least two oil filters 500 spliced ​​together, which facilitates the disassembly and installation of each oil filter 500 and makes cleaning the oil filter 500 easier. The reduced size also allows the oil filter 500 to be easily placed in a sink or dishwasher during cleaning. Furthermore, by providing at least one forward-protruding limiting part on the front surface of the oil filter 500, when the smoke guide plate 200 closes the smoke inlet 120, the limiting part abuts against the smoke guide plate 200, thereby limiting and supporting the smoke guide plate 200 and preventing collapse in the middle of the smoke guide plate 200. In addition, this structure also prevents collisions between the smoke guide plate 200 and the oil filter 500, and also prevents grease from accumulating and condensing between them due to sticking. This prevents the smoke guide plate 200 from becoming stuck together with the oil filter 500 due to grease condensation and being unable to open.

[0066] Understandably, in the above structure, adjacent oil filters 500 can be connected by abutting structures, allowing each oil filter 500 to be installed and removed independently. Alternatively, adjacent oil filters 500 can also be connected by screws, snap-fit ​​connections, or other similar methods, thereby improving the installation stability of the oil filters 500 and consequently enhancing the structural stability of the range hood.

[0067] Reference Figure 3 and Figure 7 In some embodiments, the filter holes on the oil mesh 500 are provided with a folded edge (not shown in the figure) that bends into the smoke collection chamber. The folded edge can strengthen the structural strength of the oil mesh 500 and prevent the grease inside the oil mesh 500 from overflowing outward through the filter holes.

[0068] In some embodiments, the oil mesh 500 is also provided with handle holes (not shown in the figure) on both sides. This structure can provide a point of leverage for the user when the oil mesh 500 is disassembled or installed, thereby making the disassembly and installation of the oil mesh 500 more convenient.

[0069] Reference Figure 1 This utility model also proposes a range hood, which is provided with the oil guiding structure of the range hood of any of the above embodiments.

[0070] In the range hood of this utility model embodiment, by setting the oil guiding structure of the range hood of any of the above embodiments, when the smoke guide plate 200 closes the smoke inlet 120, the grease on the inner surface of the smoke guide plate 200 can flow smoothly into the smoke collection chamber 110, without accumulating or condensing between the smoke guide plate 200 and the periphery of the smoke inlet 120. This not only helps to reduce the difficulty of cleaning the range hood, but also reduces the risk that the smoke guide plate 200 and the extension 310 will stick together due to grease condensation and cannot be opened normally, thereby greatly improving the user experience.

[0071] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
