Description

Technical Field

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

[0002] Range hoods can quickly remove harmful fumes from cooking and frying, venting them outdoors and purifying the kitchen environment. Currently, top-and-side dual-suction range hoods are widely used due to their aesthetic appeal (not encroaching on cooking space) and sufficiently low-mounted air intakes, effectively drawing in and removing fumes from the rising area.

[0003] However, top-mounted dual-suction range hoods generally suffer from long oil passages and numerous oil leakage points. In existing technology, top-mounted dual-suction range hoods typically have an oil-collecting structure in the middle of the main air intake channel at the bottom of the casing or behind the condenser panel. However, if the oil-collecting structure extends to the back panel, the oil stains in the middle will be concentrated and noticeable, eventually covering the entire back panel and reducing the user experience. If the oil-collecting structure does not extend to the back panel, the oil stains will eventually drip onto the condenser panel at the lower air intake, also reducing the user experience.

[0004] Therefore, there is an urgent need for a range hood to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a range hood that can effectively improve the oil collection effect and enhance the user experience.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] A range hood, comprising:

[0008] A smoke collection hood has a smoke collection chamber inside. The smoke collection hood includes a panel, a back plate disposed behind the panel and opposite to the panel, a mounting plate disposed at the upper end of the panel, and two side plates disposed on the left and right sides of the panel. The panel, the back plate, the mounting plate and the two side plates are used to form the smoke collection chamber.

[0009] The panel is provided with a central smoke inlet that communicates with the smoke collection chamber;

[0010] The mounting plate is provided with a smoke inlet and an oil guide section located behind the smoke inlet and extending downward. The smoke inlet has a top smoke inlet that communicates with the smoke collection chamber. The lower end of the oil guide section extends to the rear side of the panel and is located above the middle smoke inlet. The lower end of the oil guide section has an oil guide groove. The left and right sides of the oil guide groove have oil guide sections that slope downward toward the side plate. In the left-right direction, the middle smoke inlet is located between the left and right ends of the oil guide groove.

[0011] The range hood described in this utility model has the following advantages compared with the prior art:

[0012] This invention utilizes a back plate, front panel, side plates, and a mounting plate to form a smoke collection chamber. The mounting plate features a top smoke inlet and an oil guide section, allowing oil fumes to enter the collection chamber through the top smoke inlet, condense, and then be collected by the oil guide section. Specifically, the lower end of the mounting plate extends to the rear side of the front panel, and the lower end of the oil guide section has an oil guide groove. Both ends of the oil guide groove have downward-sloping oil guide sections facing the side plates. These downward-sloping sections guide the oil to both sides of the smoke collection chamber. Compared to existing technologies where oil fumes directly accumulate in the center of the back plate, this invention effectively guides the oil to both sides, preventing oil stains from forming in the center of the back plate and affecting its appearance. The oil guide groove effectively collects oil at the lower end of the mounting plate and allows the oil to flow along the bottom of the groove, improving the oil collection efficiency. Furthermore, by directly integrating the oil guide section onto the mounting plate, the need for additional oil guide structures within the smoke collection chamber is reduced, simplifying the structure and minimizing processing and installation steps. Moreover, in the left-right direction, the central smoke inlet is located between the left and right ends of the oil guide groove, ensuring that the oil flowing to the lower end of the oil guide section does not pass through the user's line of sight, thus enhancing the user experience.

[0013] In one embodiment, the end of the oil guide section extends to the side plate.

[0014] In one embodiment, the side plate is provided with an oil guiding protrusion protruding toward the smoke collection chamber, and the left and right ends of the mounting plate extend to the side plate respectively, and the end of the oil guiding section overlaps with the oil guiding protrusion.

[0015] In one embodiment, the range hood further includes an oil cup located below the smoke collection hood, and the lower end of the oil guiding protrusion is projected vertically into the oil cup.

[0016] In one embodiment, the oil guiding groove is further provided with an intermediate section between the two oil guiding sections, and the intermediate section extends in a horizontal direction.

[0017] In one embodiment, the range hood is further provided with a volute located above the smoke collection hood, and an oil leakage hole is provided at the lower end of the volute. The projection of the oil guide part in the vertical direction is located behind the projection of the oil leakage hole in the vertical direction.

[0018] In one embodiment, the front side of the panel and the two side panels enclose a smoke-collecting space; or, the distance between the upper edge of the panel and the front edge of the side panels is not less than 70 mm.

[0019] In one embodiment, a smoke inlet channel is formed between the upper edge of the panel and the mounting plate, and the smoke inlet channel communicates with the smoke collection chamber.

[0020] In one embodiment, the distance between the upper edge of the panel and the mounting plate in the front-to-back direction is less than or equal to 30 mm. Attached Figure Description

[0039] like Figures 1-7As shown, this embodiment provides a range hood, which includes a smoke collection hood 100. The smoke collection hood 100 has a smoke collection chamber 101 formed inside. The smoke collection hood 100 includes a panel 200, a back plate 120 disposed behind and opposite to the panel 200, a mounting plate 300 disposed at the upper end of the panel 200, and two side plates 110 disposed on the left and right sides of the panel 200. The panel 200, back plate 120, mounting plate 300, and two side plates 110 are used to form the smoke collection chamber 101. A central smoke inlet is provided on the panel 200, communicating with the smoke collection chamber 101. The mounting plate 300 is provided with a smoke inlet 350 and an oil guide 360 ​​extending downward from the rear side of the smoke inlet 350. The smoke inlet 350 is provided with a top smoke inlet 310 communicating with the smoke collection chamber 101. The lower end of the oil guide 360 ​​extends to the rear side of the panel 200 and is located above the middle smoke inlet 210. The lower end of the oil guide 360 ​​is provided with an oil guide groove 330. The left and right sides of the oil guide groove 330 are provided with oil guide sections 320 that slope downward toward the side plate 110. In the left and right direction, the middle smoke inlet 210 is located between the left and right ends of the oil guide groove 330.

[0040] A back panel 120, a front panel 200, a side panel 110, and a mounting plate 300 are used to form a smoke collection chamber 101. The mounting plate 300 is provided with a smoke inlet 350 and an oil guiding section 360. The smoke inlet 350 has a top smoke inlet 310, allowing oil fumes to enter the smoke collection chamber 101 from the top smoke inlet 310 and be condensed, thus achieving the collection of oil fumes by the range hood. Simultaneously, the oil guiding section 360 guides the flow of the condensed oil. Specifically, the lower end of the mounting plate 300 extends to the rear side of the panel 200, and the lower end of the oil guiding part 360 is provided with an oil guiding groove 330. Both ends of the oil guiding groove 330 are provided with oil guiding sections 320 that slope downwards towards the side plate 110. By providing oil guiding sections 320 that slope downwards towards the side plate 110, the oil is guided to both sides of the smoke collection chamber 101. Compared to the prior art where oil fumes directly accumulate in the middle of the back plate 120, this invention effectively guides the oil in the middle to both sides using the oil guiding sections 320 that slope downwards towards the side plate 110, thus preventing oil stains from appearing in the middle of the back plate 120 and affecting its appearance. The oil guiding groove 330 effectively collects the oil at the lower end of the mounting plate 300, and allows the oil to flow along the bottom of the groove, improving the oil collection efficiency. Furthermore, by directly integrating the oil guide section 360 into the mounting plate 300, the need for additional oil guide structures within the smoke collection chamber 101 is reduced, simplifying the structure and minimizing processing and installation steps. Moreover, in the left-right direction, the central smoke inlet 210 is located between the left and right ends of the oil guide groove 330, ensuring that the oil flowing to the lower end of the oil guide section 320 does not pass through the user's line of sight, thus enhancing the user experience.

[0041] In this embodiment, as Figure 5 As shown, the oil guiding groove 330 is located at the lower end of the mounting plate 300, away from the panel 200. The groove depth H1 of the oil guiding groove 330 is greater than 7mm; the width L3 of the oil guiding groove 330 in the front-to-back direction is greater than 3mm. The above parameters ensure that the oil guiding groove 330 has sufficient capacity to hold oil, and even with a large amount of oil, there will be no overflow, thus improving the reliability of oil guiding.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the range hood also includes a fan box 500 located above the smoke collection hood 100. The fan box 500 contains a volute 510, and the lower end of the volute 510 has an oil drain hole. The projection of the oil guiding part 360 in the vertical direction is located behind the projection of the oil drain hole in the vertical direction. That is, the oil guiding part 360 can effectively collect oil dripping from the oil drain hole of the volute 510, further improving the collection and guidance of oil in the smoke collection chamber 101.

[0043] In this embodiment, a smoke inlet channel 201 is formed between the upper edge of the panel 200 and the mounting plate 300, and the smoke inlet channel 201 communicates with the smoke collection chamber 101. By setting the smoke inlet channel 201, it is beneficial to improve the efficiency of the range hood in collecting oil fumes.

[0044] In other embodiments, the distance between the upper edge of the panel 200 and the mounting plate 300 in the front-to-back direction is less than or equal to 30 mm. If this distance is set too large, the depth of the smoke collection chamber 101 in the front-to-back direction will be insufficient, thus affecting the flow of smoke within the smoke collection chamber 101 and resulting in a poorer smoke extraction effect. It is worth noting that the distance can also be set to 0. In this case, the upper edge of the panel 200 overlaps with the front side of the mounting plate 300, and there is no longer a smoke inlet channel 201; smoke can only enter the smoke collection chamber 101 through the top smoke inlet 310 and the middle smoke inlet 210.

[0045] In this embodiment, the end of the oil guiding section 320 extends to the side plate 110. This allows the oil to be guided to the side plate 110, preventing the oil from dripping and ensuring the user doesn't see it dripping from the central smoke inlet 210, thus improving the user experience. Simultaneously, extending the end of the oil guiding section 320 to the side plate 110 allows the oil to slide down the side plate 110, which is more efficient than collecting oil by dripping; furthermore, it doesn't affect other structures and effectively reduces oil contamination of the structure behind the panel 200.

[0046] Preferably, the side plate 110 is provided with an oil guiding protrusion 111 protruding towards the smoke collection chamber 101. The left and right sides of the mounting plate 300 extend to the side plate 110 respectively, and the end of the oil guiding section 320 overlaps with the oil guiding protrusion 111. The oil guiding protrusion 111 not only increases the strength of the side plate 110, but also guides the oil in the oil guiding section 320, allowing the oil to flow in the extending direction of the oil guiding protrusion 111. Compared with the absence of the oil guiding protrusion 111, where the oil flows freely on the side plate 110, the oil is guided by the oil guiding protrusion 111 to flow along a planned path, facilitating the final collection of the oil. At the same time, it avoids large-area contamination of the side plate 110 by the oil, improving the cleanliness of the other parts of the side plate 110 except for the parts with the oil guiding protrusion 111.

[0047] To improve the reliability of the oil guide protrusion 111 receiving the oil in the oil guide section 320, such as Figure 3 and Figure 4 As shown, the overlap length L1 between the end of the oil guide section 320 and the projection of the oil guide protrusion 111 along the front-to-back direction is not less than 7mm, so as to avoid the problem that the oil in the oil guide section 320 cannot flow smoothly to the oil guide protrusion 111, which would lead to the failure of oil guiding.

[0048] Optionally, in this embodiment, the oil-guiding protrusion 111 is inclined from top to bottom toward the rear of the range hood to match the installation angle of the panel 200. At this time, the end of the oil-guiding section 320 abuts against the rear end of the oil-guiding protrusion 111. Furthermore, the projection of the lower end of the oil-guiding section 320 in the front-rear direction is located below the upper edge of the panel 200 to avoid the smoke entering the smoke collection chamber 101 through the smoke inlet channel 201 from blowing the oil-guiding section 320.

[0049] In other embodiments, the oil guiding protrusion 111 may extend in different directions. Those skilled in the art can set the overlapping position and overlapping angle of the oil guiding section 320 and the oil guiding protrusion 111 according to the extension direction of the oil guiding protrusion 111. As long as the oil guiding protrusion 111 can guide the oil guiding section 320 well, no specific limitation is made here.

[0050] In this embodiment, the range hood also includes an oil cup 400 located below the smoke collection hood 100. The lower end of the oil-guiding protrusion 111 is projected vertically into the oil cup 400, allowing the oil guided by the protrusion 111 to drip into the oil cup 400 for easy collection. The oil cup 400 is detachably connected to the smoke collection hood 100 for easy cleaning. Optionally, the lower end of the oil-guiding protrusion 111 is inclined rearward to improve the reliability of oil guidance and to fit the position of the oil cup 400. For example, the protrusion height of the oil-guiding protrusion 111 is greater than 7mm, which increases structural strength and guides oil without occupying too much space in the smoke collection chamber 101. The cross-sectional shape of the oil-guiding protrusion 111 is not specifically limited here.

[0051] It is worth noting that the vertical projection of the lower end of the panel 200 is also located inside the oil cup 400, meaning that the oil falling along the panel 200 can also be collected by the oil cup 400.

[0052] Furthermore, a smoke-collecting space is provided between the front side of the panel 200 and the two side panels 110. It can be understood that the lower end of the panel 200 is inclined towards the inner side of the smoke collection chamber 101, creating a smoke-collecting space between the front side of the panel 200 and the two side panels 110. This arrangement helps to increase the depth of the smoke-control space, allowing the rising fumes to be blocked by the two side panels 110, preventing them from escaping to the left and right sides. Ultimately, the fumes are slowly drawn away by the sides of the top smoke inlet 310 or the middle smoke inlet 210, making the range hood's absorption of fumes more thorough. For example, the distance between the upper edge of the panel 200 and the front edge of the side panel 110 is not less than 70mm.

[0053] Furthermore, such as Figure 6 As shown, the angle between the oil guiding section 320 and the horizontal plane is greater than or equal to 5° to achieve a better oil guiding effect, while also reducing the obstruction of the smoke inlet 210 in the middle, resulting in less turbulence at the rear of the smoke collection chamber 101. In addition, the distance between the highest point of the oil guiding section 320 and the top smoke inlet 310 is 7mm-8mm. This facilitates the installation of the oil guiding section 320 and prevents it from obstructing the middle smoke inlet 210, thus ensuring smooth smoke intake at the middle smoke inlet 210.

[0054] In this embodiment, as Figure 7 As shown, the oil guiding groove 330 also has an intermediate section 340 between the two oil guiding sections 320, and the intermediate section 340 extends horizontally. By setting the intermediate section 340, the obstruction of the oil guiding section 320 on the oil fumes entering from the central smoke inlet 210 is reduced, thereby achieving better smoke extraction.

[0055] For example, the length of the middle section 340 is greater than 300mm to ensure that the oil guiding section 320 does not block the middle smoke inlet 210; and is less than or equal to 620mm to ensure that the oil guiding section 320 has sufficient oil guiding length.

[0056] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0057] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
