[0010] In some embodiments, the range hood further includes a frame assembly disposed on the side of the smoke collection assembly away from the smoke inlet, for discharging fluid in the smoke collection chamber to a public flue or outdoor environment; the connecting assembly includes: a first connecting portion disposed on the side of the front panel away from the smoke collection chamber; a first extension portion connected to one end of the first connecting portion near the frame assembly and extending in a direction away from the front panel; and a second extension portion connected to one end of the first extension portion away from the first connecting portion and extending in a direction away from the frame assembly, to form a first cavity.

[0011] In some embodiments, the first cavity includes a first sub-cavity, the second extension includes a first segment, the first segment is connected to the end of the first extension away from the first connection, the first connection, the first extension and the first segment form the first sub-cavity, and at least a portion of the filter assembly extends into the first sub-cavity.

[0012] In some embodiments, the first cavity includes a second sub-cavity, and the second extension further includes a second sub-segment connected to the end of the first sub-segment away from the first extension. The second sub-segment and the lower part of the filter assembly have a second sub-cavity, which is used to accommodate at least a portion of the oil storage assembly.

[0013] In some embodiments, the dimension of the connecting component along a second direction perpendicular to the first direction is L, wherein 20mm≤L≤100mm, and the second direction is parallel to the height direction of the range hood.

[0014] In some embodiments, 20mm ≤ L ≤ 40mm.

[0015] In some embodiments, the distance between the front panel and the rear panel along the first direction is D1, wherein D1 ≤ 330 mm.

[0016] In some embodiments, the sum of the dimension L of the connecting component along the second direction and the distance D1 between the front plate and the rear plate along the first direction satisfies: L + D1 = 350 mm.

[0017] In some embodiments, the range hood is embedded in the first cabinet, and the front end face of the connecting component is flush with the front end face of the first cabinet.

[0018] The advantages of the embodiments of this application, which differ from the prior art, are as follows: This application provides a range hood, which includes a smoke collection assembly, a connecting assembly, and a filtering assembly. The smoke collection assembly includes a front plate and a rear plate disposed opposite to each other along a first direction, and a smoke collection chamber is formed between the front plate and the rear plate.

[0030] This application provides a range hood 100. Please refer to... Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of the range hood provided in this application; Figure 2 This is a cross-sectional view of an embodiment of the range hood provided in this application; Figure 3 yes Figure 2 The enlarged view of part A in the figure shows the range hood 100, which includes a smoke collection assembly 10, a connecting assembly 20, and a filter assembly 30. The smoke collection assembly 10 includes a front plate 11 and a rear plate 12 disposed opposite each other along a first direction XX, and a smoke collection chamber 13 is formed between the front plate 11 and the rear plate 12. The smoke collection chamber 13 has a smoke inlet 13a. The connecting assembly 20 is connected to the front plate 11 and is at least partially located on the side of the front plate 11 facing away from the smoke collection chamber 13. The connecting assembly 20 forms a first cavity 21 communicating with the smoke collection chamber 13, and the first cavity 21 is located on the side of the front plate 11 facing away from the smoke collection chamber 13. The filter assembly 30 is disposed within the smoke collection chamber 13, and at least a portion of the filter assembly 30 extends into the first cavity 21. The filter assembly 30 is used to filter the fluid flowing into the smoke collection chamber 13 via the smoke inlet 13a.

[0031] The range hood 100 can capture fumes, steam, hot air, and combustion products generated by cooking appliances during cooking, but is not limited to these. In this application embodiment, fumes, steam, hot air, and combustion products are collectively referred to as airflow. The range hood 100 can be a wall-mounted range hood 100, a side-draft range hood 100, or a built-in range hood 100, but is not limited to these. This application embodiment describes a built-in range hood 100 as an example.

[0032] The front panel 11 and the rear panel 12 are located on opposite sides of the smoke collection chamber 13 along the first direction XX. The front panel 11 is located on the side of the smoke collection assembly 10 closest to the user, and the rear panel 12 is located on the side of the smoke collection assembly 10 furthest from the user. The range hood 100 can be installed in a pre-installation area, which can be located on the back wall of a cabinet, at least via the rear panel 12. The pre-installation area can be selected according to the installation environment of the range hood 100. The rear panel 12 can be installed in the pre-installation area by means of bolt connection, anchor bolt connection, bracket connection, magnetic adsorption connection, or suction cup connection, but is not limited to these methods.

[0033] The smoke collection chamber 13 is provided with a smoke inlet 13a. The range hood 100 draws the fluid generated by the cooking utensils during the cooking process into the smoke collection chamber 13 through the smoke inlet 13a.

[0034] The connecting assembly 20 can be connected to the side of the front plate 11 facing away from the smoke collection chamber 13, so that the first cavity 21 formed by the connecting assembly 20 is located on the side of the front plate 11 facing away from the smoke collection chamber 13, and the first cavity 21 communicates with the smoke collection chamber 13. A filter assembly 30 for filtering the fluid flowing into the smoke collection chamber 13 through the smoke inlet 13a is disposed in the smoke collection chamber 13, and a portion of the filter assembly 30 extends from the smoke collection chamber 13 into the first cavity 21.

[0035] By connecting the connecting component 20 to the front panel 11 of the smoke collection component 10, and forming a first cavity 21 communicating with the smoke collection cavity 13 on the side of the front panel 11 facing away from the smoke collection cavity 13, at least a portion of the filter component 30, which is disposed in the smoke collection cavity 13 and is used to filter the fluid flowing into the smoke collection cavity 13 through the smoke inlet 13a, extends into the first cavity 21. This achieves forward movement of the filter component 30 for allowing the fluid to pass through, thereby moving the negative pressure area where the range hood 100 can capture the fluid forward. This improves the capture effect of the range hood 100 on the fluid escaping towards the front, thereby improving or preventing problems such as fluid splashing towards the user, and helping to improve the user experience.

[0036] In some embodiments, please continue to refer to Figures 2 to 3 The range hood 100 also includes an oil collection assembly 40. The oil collection assembly 40 is located below the filter assembly 30 and is at least partially located within the first cavity 21.

[0037] The oil storage component 40 can be fixed to the side of the connecting component 20 facing the first cavity 21. The oil storage component 40 can be fixed to the connecting component 20 by means of snap-fit ​​connection, magnetic adsorption connection or slide rail connection, etc., but is not limited to these.

[0038] The oil collection component 40 is used to collect and store impurities such as grease particles and liquid oil droplets intercepted by the filter component 30, but is not limited to these. At least a portion of the oil collection component 40 is located within the first cavity 21, that is, the oil collection component 40 is located on the side of the smoke collection component 10 near the front panel 11. Compared to placing the oil collection component 40 on the side of the smoke collection component 10 near the rear panel 12, placing the oil collection component 40 on the side of the smoke collection component 10 near the front panel 11 allows users to install or remove the oil collection component 40 without having to extend their body into the rear of the range hood 100. They can install or remove the oil collection component 40 from the front of the range hood 100, thus improving the efficiency of oil cup assembly installation and removal.

[0039] The oil storage assembly 40 may be located entirely within the first cavity 21; or, a portion of the oil storage assembly 40 may be located within the first cavity 21, and another portion of the oil storage assembly 40 may extend from the first cavity 21 into the smoke collection cavity 13.

[0040] By placing at least a portion of the oil storage component 40 within the first cavity 21, compared to placing the oil storage component 40 directly within the smoke collection cavity 13, the space occupied by the oil storage component 40 in the smoke collection cavity 13 and the area covered by the smoke inlet 13a can be reduced. Alternatively, the oil storage component 40 can be prevented from occupying space in the smoke collection cavity 13 and covering the smoke inlet 13a. This reduces the possibility of obstructing the area of ​​the filter component 30 where fluid can pass through, thereby expanding the negative pressure area where the range hood 100 effectively captures the fluid and improving the efficiency of smoke extraction. Moving the negative pressure area of ​​the range hood 100, which has the effect of capturing fluid, forward can further improve the capture effect of the range hood 100 on fluid escaping towards the front. On the other hand, extending a part of the oil storage component 40 from the first cavity 21 into the smoke collection cavity 13 can increase the area of ​​the downward projection of the filter component 30 onto the oil storage component 40, thereby improving the collection effect of the oil storage component 40 on the impurities intercepted by the filter component 30, reducing or avoiding impurities falling onto the stove, and further improving the user experience.

[0041] In some embodiments, please continue to refer to Figure 3 The front plate 11 is bent at one end near the smoke inlet 13a to form a recess 111 and a protrusion 112 on the side of the front plate 11 facing away from the smoke collection chamber 13. The connecting component 20 is provided in the recess 111 and protrudes from the protrusion 112 on the side facing away from the smoke collection chamber 13.

[0042] The front plate 11 can be formed with recesses 111 and protrusions 112 by bending, rolling, stamping or hydraulic methods, but is not limited to these methods. By forming recesses 111 and protrusions 112 on the front plate 11, the structural strength of the front plate 11 can be enhanced, thereby improving the load-bearing capacity of the front plate 11 on the oil storage assembly 40 and reducing the risk of deformation or cracking of the front plate 11.

[0043] In some embodiments, the front panel 11 may also extend along a second direction ZZ perpendicular to the first direction XX, so that the side of the front panel 11 facing and away from the smoke collection chamber is a plane. The second direction ZZ is parallel to the height direction of the range hood 100.

[0044] In some embodiments, please continue to refer to Figures 2 to 3The filter assembly 30 is inclined relative to the first direction XX, and the angle between the side of the filter assembly 30 facing the smoke inlet 13a and the rear plate 12 is acute. This results in the side of the filter assembly 30 near the front plate 11 being lower in height along the second direction ZZ than the side near the rear plate 12. This allows impurities intercepted by the side of the filter assembly 30 near the rear plate 12 to move along the side of the filter assembly 30 towards the oil storage assembly 40 under the influence of gravity and drip into the oil storage assembly 40. This allows the oil storage assembly 40 to collect more impurities, improving or preventing impurities from dripping onto the stovetop and thus enhancing the user experience.

[0045] By extending at least a portion of the filter assembly 30 into the first cavity 21, it also helps to increase the degree of inclination of the filter assembly 30 relative to the first direction XX, that is, it can reduce the angle between the side of the filter assembly 30 facing the smoke inlet 13a and the rear plate 12, making the filter assembly 30 more inclined, thereby improving the movement efficiency of the impurities intercepted by the filter assembly 30 and further reducing the risk of impurities dripping onto the stove.

[0046] In some embodiments, please continue to refer to Figure 3 The filter assembly 30 includes a frame 31 and a filter body 32. The frame 31 is disposed around the filter body 32. The oil storage assembly 40 forms an oil storage tank 40a and a slot 40b communicating with the oil storage tank 40a. A support member 60 is provided on the side of the slot 40b near the connecting assembly 20, at least a portion of the frame 31 is supported on the support member 60, and at least a portion of the filter body 32 extends above the slot 40b.

[0047] The frame 31 serves as a fixing and mounting structure for the filter body 32. The frame 31 is used to fix the filter body 32 to the smoke collection assembly 10 and / or the connecting assembly 20. The filter body 32 is the structure that enables the filter assembly 30 to achieve its filtering effect; the filter body 32 can be an oil filter.

[0048] The frame 31 and the filter body 32 can be a single integrated structure. The frame 31 and the filter body 32 can be integrally formed by injection molding, 3D printing, stamping, etc., but are not limited to these methods. The integral forming of the frame 31 and the filter body 32 can enhance the structural strength and stability of the filter assembly 30.

[0049] The frame 31 and the filter body 32 can also be separate structures. In some embodiments, the frame 31 and the filter body 32 are fixedly connected together by at least one of the following connection methods: welding, snap-fit ​​connection, magnetic adsorption connection, bolt connection, etc., but are not limited thereto.

[0050] The slot 40b of the oil storage assembly 40, which connects to the oil storage tank 40a, is oriented towards the filter assembly 30. The support member 60 is located on the side of the slot 40b closest to the connecting assembly 20. The support member 60 can be a structure disposed on the connecting assembly 20 facing the first cavity 21. Alternatively, the support member 60 can be a structure disposed on the oil storage assembly 40. The support member 60 can be fixed to or integrally formed with the oil storage assembly 40 or the connecting assembly 20.

[0051] The frame 31 of the filter assembly 30 extends into the first cavity 21. The frame 31 can be fixedly connected to or interference-fitted with the connecting assembly 20. At least part of the frame 31 is supported on the support member 60, which can improve the connection stability of the filter assembly 30 and reduce the risk of the filter assembly 30 shaking or falling off.

[0052] By extending at least a portion of the filter body 32 above the slot 40b, impurities dripping from the filter body 32 can fall precisely through the slot 40b into the oil storage tank 40a, thereby improving the collection effect of the oil storage assembly 40 on the impurities intercepted by the filter assembly 30.

[0053] In some embodiments, please continue to refer to Figure 3 The oil storage assembly 40 includes a second connecting portion 41, a bottom portion 42, and a flow guide portion 43. The second connecting portion 41 is connected to the side of the connecting assembly 20 near the first cavity 21. The bottom portion 42 is connected to the end of the second connecting portion 41 away from the filter assembly 30 and extends towards the smoke collection cavity 13. The flow guide portion 43 is connected to the end of the bottom portion 42 opposite to the second connecting portion 41 to form an oil storage tank 40a. The flow guide portion 43 extends towards the filter assembly 30 and is inclined away from the second connecting portion 41. The flow guide portion 43 is used to guide external airflow to the filter assembly 30.

[0054] The guide portion 43 and the second connecting portion 41 are correspondingly provided to form an oil storage groove 40a between the guide portion 43 and the second connecting portion 41. The second connecting portion 41 can be detachably fixed to the connecting assembly 20. The detachable connection between the second connecting portion 41 and the connecting assembly 20 can be a sliding groove connection, bolt connection, snap-fit ​​connection, magnetic adsorption connection, suction cup connection, Velcro connection, or adhesive connection, but is not limited to these.

[0055] By extending the airflow guide 43 toward the filter assembly 30 and tilting it away from the second connecting part 41, the angle between the side of the airflow guide 43 facing away from the second connecting part 41 and the filter assembly 30 is obtuse. This allows the airflow guide 43 to change the direction of the airflow, forcing the airflow that might otherwise escape toward the side closer to the connecting part 20 to turn toward the filter assembly 30, thereby improving the smoke control effect of the range hood 100.

[0056] In some embodiments, the oil storage assembly 40 further includes a support (not shown). The support is located on the side of the flow guide 43 facing away from the second connection 41.

[0057] The support can be an independent structure. It can be fixedly connected to the flow guide 43 on the side facing away from the second connecting part 41. The support can be fixedly connected to the flow guide 43 by bolts, snaps, magnetic adsorption, suction cups, Velcro, or adhesive, but is not limited to these methods. Of course, the support can also be integrally formed on the flow guide 43.

[0058] By placing the support on the side of the flow guide 43 facing away from the second connection 41, the oil storage assembly 40 will not tilt toward the side of the flow guide 43 when it is disassembled and placed on a certain bearing surface. This can prevent impurities loaded in the oil storage tank 40a from being dumped and improve the loading effect of the oil storage assembly 40.

[0059] In some embodiments, the angle between the side of the flow guide 43 facing away from the second connection 41 and the filter assembly 30 is greater than or equal to 145° and less than 180°.

[0060] The angle between the side of the flow guide 43 facing away from the second connecting part 41 and the filter assembly 30 can be 145°, 146.5°, 147°, 148.2°, 149.5°, 150°, 152°, 154.5°, 155°, 157.8°, 158.5°, 159.2°, 160°, 162.5°, 164°, 165°, 166.8°, 168°, 170°, 175°, etc., but is not limited to these, and can be selected according to the actual situation.

[0061] In some embodiments, please continue to refer to Figure 2 The range hood 100 also includes a frame assembly 50. The frame assembly 50 is located on the side of the smoke collection assembly 10 away from the smoke inlet 13a, and is used to discharge fluid from the smoke collection chamber 13 to a common flue or the outdoor environment. By positioning the frame assembly 50 on the side of the smoke collection assembly 10 away from the smoke inlet 13a, fluid can be more effectively guided to a common flue or the outdoor environment, reducing fluid accumulation inside the range hood 100.

[0062] The frame assembly 50 includes a frame body 51, a fan assembly 52, and an air duct 53. The frame body 51 is connected to the side of the smoke collection assembly 10 away from the smoke inlet 13a, and the frame body 51 forms a second cavity 51a communicating with the smoke collection chamber 13. The air duct 53 is disposed within the second cavity 51a and fixed to the inner wall of the frame body 51. The air duct 53 can be a volute, or other structures.

[0063] The duct 53 can be directly connected to the external environment or a public flue; or, the duct 53 can also be connected to the external environment or a public flue through a pipe assembly (not shown in the figure). That is, a pipe assembly can be installed at the exhaust port 53a of the duct 53, the pipe assembly is connected to the duct 53, and the end of the pipe assembly away from the exhaust port 53a is connected to the external environment or a public flue.

[0064] The smoke collection assembly 10 and the frame body 51 can be fixedly connected together. The fixed connection methods include welding, bolting, snap-fitting, or magnetic adsorption, but are not limited to these. A sealing structure (not shown) can be provided between the smoke collection assembly 10 and the frame body 51 to improve the connection strength and sealing performance, reducing or preventing fluid escape from the smoke collection chamber 13 between the smoke collection assembly 10 and the frame body 51. Alternatively, the smoke collection assembly 10 and the frame body 51 can be integrally formed, which can also improve the connection strength and sealing performance between them.

[0065] In some embodiments, please continue to refer to Figure 3 The connecting assembly 20 includes a first connecting portion 22, a first extension portion 23, and a second extension portion 24. The first connecting portion 22 is located on the side of the front plate 11 facing away from the smoke collection chamber 13. The first extension portion 23 is connected to the end of the first connecting portion 22 near the frame assembly 50 and extends in a direction away from the front plate 11. The second extension portion 24 is connected to the end of the first extension portion 23 away from the first connecting portion 22 and extends in a direction away from the frame assembly 50 to form a first cavity 21.

[0066] The first connecting part 22, the first extension part 23 and the second extension part 24 are connected in sequence to form a first sub-cavity 211 that connects to the smoke collection chamber 13. The first sub-cavity 211 can accommodate at least a portion of the frame 31 of the filter assembly 30 and the oil storage assembly 40, so as to reduce the space occupied by the oil storage assembly 40 and the frame 31 which does not have the filtering effect on the smoke collection chamber 13 and the coverage area of ​​the smoke inlet 13a, or to avoid the oil storage assembly 40 and the frame 31 occupying the space of the smoke collection chamber 13 and covering the smoke inlet 13a. This reduces the possibility that the area of ​​the filter assembly 30 that allows fluid to pass through will be blocked, expands the negative pressure area of ​​the range hood 100 that has the effect of capturing fluid, and moves the negative pressure area of ​​the range hood 100 that has the effect of capturing fluid forward, thereby further improving the capture effect of the range hood 100 on the fluid escaping towards the front.

[0067] The connection between the first connecting part 22 and the first extension part 23, as well as the connection between the first extension part 23 and the second extension part 24, are all smoothly transitioned. This not only improves the structural stability and durability of the connecting component 20 and reduces damage caused by stress concentration, but also makes the corners of the connecting component 20 smooth, making the range hood 100 more beautiful and elegant, and increasing the aesthetic appeal of the design.

[0068] In some embodiments, the dimension of the front plate 11 along the second direction ZZ is smaller than the dimension of the rear plate 12 along the second direction ZZ, and the end of the front plate 11 away from the frame assembly 50 is higher than the end of the rear plate 12 away from the frame assembly 50 in the second direction ZZ, so that the front plate 11 will not block the space between the first cavity 21 and the smoke collection cavity 13, thereby allowing the first cavity 21 and the smoke collection cavity 13 to communicate. Furthermore, the side of the connecting assembly 20 away from the frame assembly 50, the side of the oil storage assembly 40 away from the filter assembly 30, and the end of the rear plate 12 away from the frame assembly 50 are at the same height, that is, the second extension 24 of the connecting assembly 20 is away from the end of the first extension 23, the side of the bottom plate of the oil storage assembly 40 away from the oil storage tank 40a, and the end of the rear plate 12 away from the frame assembly 50 are at the same height, so that the arrangement of the connecting assembly 20 and the oil storage assembly 40 will not affect the overall height of the range hood 100, thereby reducing or avoiding the risk of users bumping their heads.

[0069] In some embodiments, the first cavity 21 includes a first sub-cavity 211. The second extension 24 includes a first segment 241 connected to one end of the first extension 23 away from the first connecting portion 22. The first connecting portion 22, the first extension 23, and the first segment 241 form the first sub-cavity 211, and at least a portion of the filter assembly 30 extends into the first sub-cavity 211.

[0070] The first sub-segment 241 is part of the second extension 24. Both the first sub-segment 241 and the first connecting portion 22 extend along the second direction ZZ, and are spaced apart along the first direction XX. The first extension 23 connects the first sub-segment 241 and the first connecting portion 22, and is located on the side of the first sub-segment 241 and the first connecting portion 22 closest to the rack assembly 50. The first sub-cavity 211 is located on the side of the first sub-segment 241 and the first connecting portion 22 furthest from the rack assembly 50.

[0071] The first sub-cavity 211 is adapted to the side of the filter assembly 30 near the front panel 11. The side of the filter assembly 30 near the front panel 11 can be embedded in the first sub-cavity 211 by an interference fit, thereby saving the need for fixing parts for fixing the filter assembly 30 on that side. On the one hand, this reduces the overall weight of the range hood 100 and lowers its overall cost. On the other hand, during the installation of the filter assembly 30, the side of the filter assembly 30 near the front panel 11 can be embedded in the first sub-cavity 211 first, and then the other sides can be fixed. During the disassembly of the filter assembly 30, the other sides of the filter assembly 30 can be removed after disassembly, thereby improving the efficiency of installation and disassembly of the filter assembly 30 and facilitating regular cleaning of the filter assembly 30. Of course, the side of the filter assembly 30 near the front panel 11 can also be installed in the first sub-cavity 211 by means of snap-fit ​​connection, magnetic adsorption connection, or bolt connection.

[0072] In some embodiments, the first cavity 21 includes a second sub-cavity 212. The second extension 24 further includes a second segment 242. The second segment 242 is connected to the end of the first segment 241 away from the first extension 23. The second segment 242 and the lower portion of the filter assembly 30 have a second sub-cavity 212. The second sub-cavity 212 is used to receive at least a portion of the oil storage assembly 40.

[0073] The second segment 242 is another part of the second extension 24. By placing at least a portion of the oil storage assembly 40 within the second sub-cavity 212, the second segment 242 can cover the front end face of the oil storage assembly 40, thereby concealing the oil storage assembly 40 and improving the uniformity of the front end face of the range hood 100, thus enhancing the aesthetic design of the range hood 100.

[0074] Please continue to refer to Figures 2 to 3 At the same time, refer to Figure 4 ,in, Figure 4 This is a cross-sectional view of another embodiment of the range hood provided in this application. The dimension of the connecting component 20 along the second direction ZZ perpendicular to the first direction XX is L, where 20mm≤L≤100mm.

[0075] The dimension L of the connecting component 20 along the second direction ZZ, that is, the vertical distance between the side of the first extension 23 facing away from the second extension 24 and the end of the second extension 24 away from the first extension 23, is L.

[0076] The dimension L of the connecting component 20 along the second direction ZZ perpendicular to the first direction XX can be 20mm, 22.5mm, 25mm, 27.85mm, 29.5mm, 30mm, 33.35mm, 35mm, 36.66mm, 38mm, 40mm, 41mm, 44.8mm, 45mm, 46.5mm, 48.55mm, 50mm, 53mm, 55mm, 57mm, 60mm, 64mm, 65mm, 66.6mm, 69mm, 70mm, 75mm, 77mm, 78.5mm, 80mm, 83mm, 85mm, 88mm, 90mm, 95mm, 100mm, etc., but is not limited to these. Specific values ​​can be selected according to actual conditions, as long as the dimension L of the connecting component 20 along the second direction ZZ is within the range of 20mm to 100mm.

[0077] By making the dimension L of the connecting component 20 along the second direction ZZ within the range of 20mm to 100mm, it is possible to ensure that the first accommodating part can simultaneously accommodate at least a portion of the filter component 30 and the oil storage component 40, while making the connecting component 20 thinner. This not only saves space occupied by the range hood 100, but also reduces the risk of bumps and knocks for users, thus improving the user experience.

[0078] In some embodiments, the dimension L of the connecting component 20 along the second direction ZZ satisfies: 20mm≤L≤40mm.

[0079] The dimension L of the connecting component 20 along the second direction ZZ can be 20mm, 21.2mm, 22.5mm, 23.55mm, 25mm, 26mm, 27.85mm, 28mm, 29.5mm, 30mm, 32.5mm, 33.35mm, 35mm, 36.66mm, 37.5mm, 38mm, 40mm, etc., but is not limited to these.

[0080] In some embodiments, please continue to refer to Figures 2 to 4 The distance between the front plate 11 and the rear plate 12 along the first direction XX is D1, where D1≤330mm.

[0081] When the front plate 11 has a recess 111 and a protrusion 112 on the side facing away from the smoke collection chamber 13, the distance between the front plate 11 and the rear plate 12 along the first direction XX can be the distance between the side of the recess 111 facing the smoke collection chamber 13 and the side of the rear plate 12 facing the smoke collection chamber 13 along the first direction XX.

[0082] The distance D1 between the front plate 11 and the rear plate 12 along the first direction XX can be 200mm, 250mm, 275mm, 280mm, 290mm, 295mm, 300mm, 306mm, 308mm, 310mm, 313mm, 315mm, 318mm, 319.5mm, 320mm, 322mm, 324.5mm, 325mm, 326.5mm, 327mm, 328.5mm, 330mm, etc., but is not limited to these. The specific value can be selected according to the actual situation.

[0083] In some embodiments, the sum of the dimension L of the connecting component 20 along the second direction ZZ and the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX satisfies: L + D1 = 350 mm.

[0084] By ensuring that the sum of the dimension L of the connecting assembly 20 along the second direction ZZ and the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX is equal to 350mm, under the premise that the dimension L of the connecting assembly 20 along the second direction ZZ is greater than or equal to 20mm and less than or equal to 100mm, and the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX is within 330mm, the smaller the dimension L of the connecting assembly 20 along the second direction ZZ, the larger the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX, or the larger the dimension L of the connecting assembly 20 along the second direction ZZ, the smaller the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX.

[0085] When the dimension L of the connecting assembly 20 along the second direction ZZ is small, the depth of the smoke collection chamber 13 along the second direction ZZ will decrease. To improve the fluid capacity of the smoke collection chamber 13, the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX can be increased. This increases the dimension of the smoke collection chamber 13 along the first direction XX to compensate for the insufficient depth of the smoke collection chamber 13 along the second direction ZZ. Similarly, when the distance D1 between the front plate 11 and the rear plate 12 along the first direction XX is small, the dimension L of the smoke collection chamber 13 along the first direction XX can be increased. This increases the fluid capacity of the smoke collection chamber 13 and helps improve the smoke extraction efficiency of the range hood 100.

[0086] Please refer to Figure 5 , Figure 5This is a schematic diagram of the structure of the range hood embedded in the first cabinet provided in this application. The range hood 100 is used to be embedded in the first cabinet 201, and the front end face of the connecting component 20 is flush with the front end face of the first cabinet 201.

[0087] By making the front end face of the connecting component 20 flush with the front end face of the first cabinet 201, the integration of the range hood 100 and the first cabinet 201 can be improved, which helps to enhance the overall aesthetics and simplicity.

[0088] In some embodiments, the range hood 100 is disposed above the second cabinet 202. A cooktop is provided on the side of the second cabinet 202 facing the range hood 100.

[0089] Please continue to refer to Figures 2 to 4 The vertical distance between the side of the connecting component 20 facing away from the stove and the stove is D2, that is, the vertical distance between the side of the first extension 23 facing away from the second extension 24 and the stove is D2, wherein 650mm≤D2≤850mm.

[0090] The vertical distance D2 between the side of the connecting component 20 facing away from the stove and the stove can be 650mm, 660mm, 680mm, 700mm, 720mm, 725mm, 740mm, 750mm, 777mm, 785mm, 799mm, 800mm, 806mm, 815mm, 820mm, 830mm, 835mm, 844mm, 850mm, etc., but is not limited to these.

[0091] This application provides a range hood 100, which includes a smoke collection assembly 10, a connecting assembly 20, and a filter assembly 30. The smoke collection assembly 10 includes a front plate 11 and a rear plate 12 disposed opposite to each other along a first direction XX, and a smoke collection chamber 13 is formed between the front plate 11 and the rear plate 12. The smoke collection chamber 13 is provided with a smoke inlet 13a. The connecting assembly 20 is connected to the front plate 11 and is at least partially located on the side of the front plate 11 away from the smoke collection chamber 13. The connecting assembly 20 forms a first cavity 21 communicating with the smoke collection chamber 13. The first cavity 21 is located on the side of the front plate 11 away from the smoke collection chamber 13. The filter assembly 30 is disposed in the smoke collection chamber 13, and at least a portion of the filter assembly 30 extends into the first cavity 21. The filter assembly 30 is used to filter the fluid flowing into the smoke collection chamber 13 through the smoke inlet 13a. By connecting the connecting component 20 to the front panel 11 of the smoke collection component 10, and forming a first cavity 21 communicating with the smoke collection cavity 13 on the side of the front panel 11 facing away from the smoke collection cavity 13, at least a portion of the filter component 30, which is disposed in the smoke collection cavity 13 and is used to filter the fluid flowing into the smoke collection cavity 13 through the smoke inlet 13a, extends into the first cavity 21. This achieves forward movement of the filter component 30 for allowing the fluid to pass through, thereby moving the negative pressure area where the range hood 100 can capture the fluid forward. This improves the capture effect of the range hood 100 on the fluid escaping towards the front, thereby improving or preventing problems such as fluid splashing towards the user, and helping to improve the user experience.
