[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0051] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0052] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0053] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The smoke inlet structure provided by the utility model can be arranged on a top suction range hood or a side suction range hood. In this embodiment, it is specifically arranged on a "7"-shaped range hood. The "7"-shaped range hood has an upper smoke collecting hood and a lower smoke collecting hood. The upper smoke collecting hood has a top smoke inlet. The lower smoke collecting hood is formed as a shell 100 and is detachably connected to the oil cup 400.

[0055] like Figure 1 - Figure 4 As shown, the bottom end surface of the housing 100 has at least two layers of oil filter structures 200 arranged in sequence from outside to inside, and each layer of the oil filter structure 200 is provided with a smoke inlet. The planes where the smoke inlet holes in the oil filter structure 200 are located can all be inclined planes, and the inclined planes are inclined backward and downward from front to back. On the one hand, the smoke inlet holes can be better oriented to the stove in the lower front, and on the other hand, the oil on the inclined plane will flow backward and downward along the inclined plane and finally fall into the oil cup 400.

[0056] An inlet 410 connecting the inside and the outside is provided on the side wall of the oil cup 400. The inside of the housing 100 has an oil fume channel, which is connected to the fan assembly. When the fan assembly is working, a negative pressure is formed in the oil fume channel. From the outside to the inside, the inlet 410, at least two smoke inlet holes and the oil fume channel are connected in sequence to form a bottom smoke inlet channel. The oil fume passes through the inlet 410, and then passes through each smoke inlet hole in sequence to enter the oil fume channel, and then is discharged by the fan assembly. In this embodiment, the inlet 410 is provided on the front side of the oil cup 400. In other feasible solutions, the inlet 410 can also be provided on other surfaces, for example, the inlet 410 is provided on both the left side and the right side.

[0057] The oil smoke can be sucked from the bottom of the housing 100 through the bottom smoke inlet channel, thereby increasing the coverage area of ​​the range hood for smoking and reducing dead corners for smoking. In addition, when the oil smoke passes through the smoke inlet hole, part of the oil smoke will condense. The purpose of providing at least two layers of oil filter structures 200 is to increase the condensation effect of the oil smoke, allowing more oil to condense at the filter structure and reduce the oil pressure at the fan assembly.

[0058] like Figure 1 As shown, the outermost oil filter structure 200 includes a first oil guide slope 512 extending from front to rear and sloping downward; the smoke inlet hole of the outermost oil filter structure 200 is the first smoke inlet hole 511, which is arranged on the first oil guide slope 512, and the first smoke inlet hole 511 passes through the inner and outer surfaces of the first oil guide slope 512.

[0059] The oil filter structure 200 may be two layers, three layers or even more. In this embodiment, three layers are used as an example. The first oil guide slope 512 can make the first smoke inlet 511 better face the stove in the lower front. On the other hand, the oil on the first oil guide slope 512 will flow backward and downward along the first oil guide slope 512 and finally fall into the oil cup 400.

[0060] The smoke inlet hole on the second outermost oil filter structure 200 is the second smoke inlet hole 622, and the first smoke inlet hole 511 and the second smoke inlet hole 622 are completely staggered vertically, so that the outermost oil filter structure 200 receives the oil stains falling from the second outermost oil filter structure 200; the outermost oil filter structure 200 is provided with an oil leakage hole 513, and the downward projection of the oil leakage hole 513 falls inside the oil cup 400.

[0061] like Fig.13As shown, after the oil smoke passes through the first smoke inlet 511, it will flow through the second smoke inlet 622 again, and condensation will occur again. A part of the oil will condense at the second smoke inlet 622, and the first smoke inlet 511 and the second smoke inlet 622 are completely staggered vertically. The oil dripping from the second smoke inlet 622 will not pass through the first smoke inlet 511, but fall on the upper surface of the outermost oil filter structure 200, and finally fall into the oil cup 400 through the oil leakage hole 513, which has the effect of preventing the oil from dripping onto the stove. In this embodiment, the number of the second smoke inlet 622 and the first smoke inlet 511 are both multiple, and the number can be the same or different. One second smoke inlet 622 is located on the left side of the corresponding first smoke inlet 511. Of course, in other feasible schemes, one second smoke inlet 622 can be located in front of the corresponding first smoke inlet 511.

[0062] Except for the outermost oil filter structure 200, the smoke inlet holes on the oil filter structures 200 of other layers may be coaxially arranged to reduce wind resistance.

[0063] like Figure 5 - Figure 8 As shown, in this embodiment, the housing 100 includes a bottom plate 710 , the bottom plate 710 forms a layer of oil filter structure 200 , and the smoke inlet hole on the bottom plate 710 is a third smoke inlet hole 712 .

[0064] The housing 100 has a frame 110, and the bottom plate 710 can be connected to the bottom opening of the frame 110, and the connection method can be welding or connection through screws. The bottom plate 710 forms the innermost oil filter structure 200. A third oil guide slope 711 can be set on the bottom plate 710, and the third smoke inlet 712 is set on the third oil guide slope 711. From front to back, the third oil guide slope 711 is inclined downward, so that the third smoke inlet 712 faces the lower front.

[0065] An oil guide hole 713 may be provided on the bottom plate 710 . The oil guide hole 713 is located behind the third oil guide slope 711 . The oil in the housing 100 may enter the oil cup 400 through the oil guide hole 713 .

[0066] Further, such as Figure 6 , 9 and Fig.10 As shown, the smoke inlet structure includes an installation back plate 610 and a decorative plate 800, the installation back plate 610 is connected to the front of the shell 100, and the decorative plate 800 is connected to the front of the installation back plate 610; the lower edge of the installation back plate 610 has a first flange 620 folded backward, the first flange 620 is located on the outer side of the bottom plate 710 and is connected to the bottom plate 710; the first flange 620 forms a layer of oil filter structure 200, and the smoke inlet hole on the first flange 620 is a second smoke inlet hole 622.

[0067] like Figure 5 As shown, the front of the frame 110 is connected to the mounting back plate 610, and the back of the mounting back plate 610 has a hook, and the frame 110 is provided with a hanging hole, and the hook is connected to the hanging hole, so that the mounting back plate 610 and the frame 110 are connected together, or the mounting back plate 610 and the frame 110 can be welded by direct welding. The first flange 620 can be provided with a through hole, and the corresponding position of the bottom plate 710 is also provided with a through hole. The first flange 620 can be connected to the bottom plate 710 by passing a screw through the first flange 620 and the bottom plate 710 and then connecting with a nut, so as to achieve a stable connection between the mounting back plate 610 and the housing 100.

[0068] like Fig.10 As shown, the first flange 620 covers the third oil guiding slope 711 from below, and the first flange 620 forms the second layer of oil filtering structure 200. From inside to outside, the oil smoke first passes through the first flange 620 and then passes through the bottom plate 710, and finally enters the inside of the housing 100. Corresponding to the third oil guiding slope 711, the first flange 620 is provided with a second oil guiding slope 621, the second oil guiding slope 621 and the third oil guiding slope 711 are parallel and attached together, and the second smoke inlet 622 and the third smoke inlet 712 are coaxially arranged.

[0069] Further, such as Fig.11 and Fig.12 As shown, the smoke intake structure includes an air intake plate 510, which forms an oil filter structure 200, and is located on the outside of the first flange 620; the air intake plate 510 includes a first oil guide slope 512 that is inclined from front to back and downward, and the smoke intake hole of the air intake plate 510 is a first smoke intake hole 511, and the first smoke intake hole 511 is arranged on the first oil guide slope 512.

[0070] In this embodiment, the air inlet plate 510 is the outermost oil filter structure 200, which is arranged outside the first flange 620. The rear end of the air inlet plate 510 can be welded to the bottom plate 710, and the upper end can be connected to the front of the decorative plate. Figure 6 As shown, along the inward and outward directions, the distance between the first oil guiding slope 512 and the second oil guiding slope 621 is greater than the distance between the second oil guiding slope 621 and the third oil guiding slope 711, so that the first smoke inlet hole 511 can be closer to the inlet 410 on the oil cup 400, so that the oil smoke entering the oil cup 400 can quickly enter the first smoke inlet hole 511. After passing through the inlet 410 of the oil cup 400, the oil smoke passes through the first smoke inlet hole 511, the second smoke inlet hole 622 and the third smoke inlet hole 712 in turn and then enters the fan assembly.

[0071] An oil leakage hole 513 is provided on the air inlet plate 510 , and the downward projection of the oil leakage hole 513 falls inside the oil cup 400 ; the first smoke inlet hole 511 and the second smoke inlet hole 622 are completely offset vertically so that the oil stains falling from the first flange 620 fall on the upper surface of the air inlet plate 510 .

[0072] The oil leakage hole 513 is located behind the first oil guide slope 512, and the oil dripping from the second smoke inlet hole 622 onto the inner side of the first oil guide slope 512 flows downward and backward and is discharged from the oil guide hole 713. The first smoke inlet hole 511 and the second smoke inlet hole 622 are completely staggered to prevent the oil from dripping onto the stove through the first smoke inlet hole 511 and the inlet 410.

[0073] like Figure 6 As shown, an inwardly protruding annular flange is provided at the edge of the first smoke inlet hole 511 to prevent oil stains on the inner side of the first oil guide slope 512 from dripping from the first smoke inlet hole 511 onto the stove.

[0074] The air inlet plate 510 includes a guide plate 514 extending upward from the upper edge of the first oil guide slope 512 . The guide plate 514 is connected to the front side of the decorative plate 800 and is used to guide the oil on the decorative plate 800 to the first oil guide slope 512 .

[0075] The drainage sheet 514 can be connected to the front of the decorative plate 800 by adhesive, and a drainage slope can be provided at the upper edge of the drainage sheet 514, so that the upper edge is better attached to the decorative plate 800. The oil on the decorative plate 800 flows down from the drainage sheet 514, flows to the outer wall of the first oil guide slope 512, and flows into the oil cup 400 along the inclined outer wall.

[0076] like Figure 6 As shown, the inlet 410 is arranged on the front wall of the oil cup 400; from top to bottom, the front wall of the oil cup 400 is inclined toward the rear side; the lower edge of the inlet 410 of the oil cup 400 has a stop edge 420 extending upward, the left end of the stop edge 420 is connected to the left edge of the inlet 410, and the right end of the stop edge 420 is connected to the right edge of the inlet 410.

[0077] The setting of the stop edge 420 can increase the total volume of the oil cup 400. If only the inlet 410 is set in the scheme without the stop edge 420, the highest liquid level of the oil cup 400 is the lower edge of the inlet 410, and the highest liquid level is relatively low. If the stop edge 420 is set, the highest liquid level will be raised to the upper edge of the stop edge 420 while ensuring that air can pass through the inlet 410. In this embodiment, the stop edge 420 is in a vertical state, and the stop edge 420 is spaced apart from the first smoke inlet 511 to avoid affecting the air intake.

[0078] The range hood provided by the utility model includes the above-mentioned smoke inlet structure. Since the range hood provided by the utility model adopts the above-mentioned smoke inlet structure, the range hood provided by the utility model also has the advantages of the smoke inlet structure.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
