Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0018] With the continuous development of science and technology, range hoods have become one of the most common kitchen appliances in people's daily lives. In existing technology, the baffle plate of a range hood typically has a baffle section and an air inlet section. After prolonged use, grease easily accumulates inside the baffle cavity, particularly at the baffle section, making it difficult to clean. How to improve the structure of the baffle plate to reduce grease accumulation at the baffle section is one of the key issues of concern to those skilled in the art.

[0019] Normally, when a range hood is in operation, the front end of the hood housing is the end closest to the user, and the rear end is positioned opposite the front end. It should be noted that, in this application, the front end or front side of a component or assembly refers to the end or side of the component or assembly closest to the user; the rear end or rear side of a component or assembly refers to the end or side of the component or assembly away from the user and opposite to the aforementioned front end or front side. This application uses the range hood's baffle plate and the range hood in operation as an example for explanation.

[0020] This application first proposes a baffle plate for a range hood, such as... Figures 1 to 6 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the range hood of this application; Figure 2 This is a cross-sectional structural schematic diagram of an embodiment of the range hood of this application; Figure 3 This is another cross-sectional structural schematic diagram of an embodiment of the range hood of this application; Figure 4 yes Figure 3 An enlarged structural diagram of region A in the embodiment; Figure 5 This is a schematic diagram of the structure of one embodiment of the air deflector; Figure 6 yes Figure 5 A bottom view of the embodiment. The guide plate 11 is provided with at least a first air inlet 111, a second air inlet 112, and a windproof part 110. The first air inlet 111 is provided with a first air inlet hole 101, and the second air inlet 112 is provided with a second air inlet hole 102. At least a portion of the windproof part 110 and at least a portion of the second air inlet 112 are located below the first air inlet 111. In the horizontal direction, the lowest end of the first air inlet hole 101 is located outside the side of the windproof part 110, and the lowest end extends toward the second air inlet hole 102.

[0021] It should be noted that when the range hood's baffle 11 is in operation, the lowest point of the component or assembly refers to the lowest point of the component or assembly in the direction of gravity. The first air inlet 101 has an extending direction, and the extending direction of the lowest point of the first air inlet 101 extends toward the location of the second air inlet 102.

[0022] It should be noted that the wind blocking part 110 is used to connect the first air inlet part 111 and the second air inlet part 112, which can improve the strength of the guide plate 11; in the direction of gravity, at least part of the wind blocking part 110 and at least part of the second air inlet part 112 are located below the first air inlet part 111, and the first air inlet part 111 is arranged adjacent to the second air inlet part 112 and the wind blocking part 110, so that the oil stains at the first air inlet part 111 can flow to the wind blocking part 110 and the second air inlet part 112 under the action of gravity. The presence of the wind blocking part 110 can realize the effect of gathering smoke in the guide cavity 105, and can improve the structural strength of the guide plate 11. Since in the horizontal direction, the lowest end of the first air inlet hole 101 and the side edge of the wind blocking part 110 are arranged in the horizontal direction, and the lowest end of the first air inlet hole 101 is located outside the side edge of the wind blocking part 110, the oil stains at the first air inlet part 111 can flow along the hole wall of the first air inlet hole 101 to the lowest end of the first air inlet hole 101 under the action of gravity, and then flow to the area outside the wind blocking part 110. Further, since the lowest end of the first air inlet hole 101 extends towards the second air inlet hole 102, the oil stains can be guided to the second air inlet hole 102, which is convenient for cleaning.

[0023] The beneficial effects of the above arrangement are that the arrangement of the first air inlet hole 101 and the second air inlet hole 102 can increase the area of the air inlet area of the guide plate 11, improve the amount of smoke suction of the range hood, the arrangement of the wind blocking part 110 can improve the appearance and the strength of the guide plate 11, and can improve the effect of gathering smoke in the guide cavity 105; at least part of the wind blocking part 110 and at least part of the second air inlet part 112 are located below the first air inlet part 111, and in the horizontal direction, the lowest end of the first air inlet hole 101 is located outside the side edge of the wind blocking part 110, and the lowest end extends towards the second air inlet hole 102, which can make the oil stains at the first air inlet part 111 flow along the hole wall of the first air inlet hole 101 to the lowest end of the first air inlet hole 101 under the action of gravity, and then be guided to the outside of the wind blocking part 110, reduce the accumulation of oil stains at the wind blocking part 110, and can guide the oil stains to the second air inlet hole 102 of the second air inlet part 112 located below the first air inlet part 111, which can improve the cleaning convenience.

[0024] In some embodiments, the second air inlet part 112 is arranged behind the first air inlet part 111.

[0025] Specifically, in the working state of the range hood, the first air inlet part 111 is arranged close to the user, and the second air inlet part 112 is arranged away from the user. This arrangement can make the oil stains at the first air inlet part 111 flow in the direction away from the user along the hole wall of the first air inlet hole 101 under the action of gravity, reducing the risk of oil dripping on the side of the range hood close to the user.

[0026] In some embodiments, the deflector 11 further comprises a third air inlet portion 113 provided with a third air inlet hole 103, and the third air inlet portion 113 is at least partially located below the first air inlet portion 111.

[0027] The above arrangement can further increase the area of the air inlet region of the deflector 11 and improve the oil fume suction capacity of the range hood.

[0028] In some embodiments, the air blocking portion 110 comprises a first sub-air blocking portion 1101 located below the first air inlet portion 111, and the second air inlet portion 112, the first sub-air blocking portion 1101 and the third air inlet portion 113 are sequentially arranged along a first direction x1, and the first direction x1 is parallel to the horizontal direction.

[0029] In this way, the first sub-air blocking portion 1101 is arranged between the second air inlet portion 112 and the third air inlet portion 113, which can improve the strength of the deflector 11; and the second air inlet portion 112 and the third air inlet portion 113 are located on the left and right sides of the first sub-air blocking portion 1101, which can improve the air inlet uniformity of the deflector 11 in the horizontal direction.

[0030] In some embodiments, referring to Figure 6 , the first air inlet portion 111 is further provided with a fourth air inlet hole 104, the fourth air inlet hole 104 and the first air inlet hole 101 are arranged along the first direction x1, and the fourth air inlet hole 104 is symmetrically arranged about a first central axis a of the first sub-air blocking portion 1101; along the first direction x1, the lowest end of the first air inlet hole 101 is located outside one side edge of the first sub-air blocking portion 1101, and the lowest end of the first air inlet hole 101 extends towards the second air inlet hole 102; along the first direction x1, the lowest end of the fourth air inlet hole 104 is located outside the other side edge of the first sub-air blocking portion 1101, and the lowest end of the fourth air inlet hole 104 extends towards the third air inlet hole 103; and the first central axis a is perpendicular to the first direction x1.

[0031] The above arrangement can further improve the oil dirt flow guiding effect at the first air inlet part 111. Specifically, in the present embodiment, it can be determined that the third air inlet part 113 is at least partially located below the first air inlet part 111, the second air inlet part 112 is at least partially located below the first air inlet part 111, the first sub air baffle part 1101 is located below the first air inlet part 111, and the second air inlet part 112, the first sub air baffle part 1101, and the third air inlet part 113 are arranged in the first direction x1 in sequence. Therefore, by the above arrangement, the oil dirt accumulation at the first air inlet part 111 can be further reduced, so that the oil dirt at the first air inlet part 111 can flow to the second air inlet hole 102 along the hole wall of the first air inlet hole 101, or flow to the third air inlet hole 103 along the hole wall of the fourth air inlet hole 104, so as to facilitate cleaning. Further, the symmetrical arrangement of the first air inlet hole 101 and the fourth air inlet hole 104 can improve the appearance and improve the uniformity of the oil fume suction of the range hood; and the symmetrical arrangement can make the oil dirt near the second air inlet hole 102 be guided to the vicinity of the second air inlet hole 102, and the oil dirt near the third air inlet hole 103 be guided to the vicinity of the third air inlet hole 103, so as to realize flow distribution and improve the uniformity of oil guiding. In other embodiments, the first air inlet hole 101 and the fourth air inlet hole 104 can also be asymmetrically arranged.

[0032] In other embodiments (not shown in the figure), the first air inlet part is further provided with a fifth air inlet hole, and the fifth air inlet hole includes a plurality of lowest ends, for example, when the fifth air inlet hole is an X-shaped air inlet hole, it can include a first lowest end and a second lowest end. Among them, along the horizontal direction, the first lowest end is arranged outside one side of the first sub air baffle part to extend towards the second air inlet hole; along the horizontal direction, the second lowest end is arranged outside the other side of the first sub air baffle part to extend towards the third air inlet hole.

[0033] In some embodiments, the two side edges of the first sub air baffle part 1101 are oppositely arranged and arranged in the first direction x1, which can improve the convenience of arranging the lowest end of the first air inlet hole 101 and the lowest end of the fourth air inlet hole 104.

[0034] In some embodiments, the third air inlet part 113 is arranged behind the first air inlet part 111.

[0035] Specifically, in the working state of the range hood, the first air inlet part 111 is arranged close to the side of the user, and the third air inlet part 113 is arranged away from the side of the user. This arrangement can make the oil dirt at the first air inlet part 111 flow in the direction away from the user along the hole wall of the fourth air inlet hole 104 under the action of gravity, reducing the risk of oil dripping on the side of the range hood close to the user.

[0036] In some embodiments, as Figure 6As shown, the third air inlet hole 103 is symmetrically arranged with the second air inlet hole 102 about the first central axis a of the first sub wind blocking part.

[0037] The above arrangement can improve the uniformity of smoke suction of the range hood. Specifically, the symmetric arrangement can improve the uniformity of the arrangement of the third air inlet hole 103 on the third air inlet part 113 and the arrangement of the second air inlet hole 102 on the second air inlet part 112, thereby improving the uniformity of smoke suction of the range hood and improving the aesthetics of the overall structure. Further, since the first sub wind blocking part 1101 can improve the strength of the deflector 11, the above arrangement can improve the uniformity of the overall strength of the deflector 11.

[0038] In some embodiments, referring to Figure 6 As shown, the wind blocking part 110 includes a first sub wind blocking part 1101 located below the first air inlet part 111, and the projection of the extension direction of the lowest end of the first air inlet hole 101 in the horizontal plane is arranged at a first included angle A1 with the second direction x2, which is the arrangement direction of the projection of the first sub wind blocking part 1101 and the first air inlet part 111 in the horizontal plane.

[0039] The above arrangement can guide the oil dirt at the first air inlet part 111 to the outside of the first sub wind blocking part 1101 with a simpler structure, thereby reducing the accumulation of oil dirt at the first sub wind blocking part 1101. Specifically, since the lowest end of the first air inlet hole 101 is located outside the side of the first sub wind blocking part 1101, in this embodiment, by arranging the projection of the extension direction of the lowest end of the first air inlet hole 101 in the horizontal plane at an included angle with the arrangement direction of the projection of the first sub wind blocking part 1101 and the first air inlet part 111 in the horizontal plane, the hole wall of the extension part can be inclined to extend away from the first sub wind blocking part 1101, thereby achieving the guiding of oil dirt to the area outside the first sub wind blocking part 1101 through the inclined extension.

[0040] In some embodiments, the first included angle A1 is greater than 0 degrees and less than or equal to 83 degrees.

[0041] For example, the first included angle A1 can be 5 degrees, 10 degrees, 15 degrees, 18 degrees, 20 degrees, 25 degrees, 28 degrees, 36 degrees, 55 degrees, 63 degrees, 79 degrees, or 83 degrees, etc.

[0042] The above arrangement can further optimize the oil guiding effect. Specifically, the larger the first included angle A1, the more oil dirt can be guided to the outside of the first sub wind blocking part 1101; but when the first included angle A1 is too large, for example, 90 degrees, it will be not conducive to the flow of oil dirt along the hole wall of the first air inlet hole 101 under the action of gravity, therefore, limiting the first included angle A1 to be greater than 0 degrees and less than or equal to 83 degrees can improve the oil guiding effect.

[0043] Preferably, the first included angle A1 is greater than or equal to 30 degrees and less than or equal to 80 degrees. This further optimizes the oil guiding effect. For example, the first included angle A1 can be 30 degrees, 35 degrees, 40 degrees, 46 degrees, 50 degrees, 52 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, or 80 degrees, etc.

[0044] In other embodiments, similar improvements can be made for the fourth air inlet hole 104, for example, the projection of the extension direction of the lowest end of the fourth air inlet hole 104 in the horizontal plane is set to have a first included angle A1 with the second direction x2, which will not be described here.

[0045] In some embodiments, the first air inlet hole 101 is arranged in a curved or zigzag line.

[0046] This arrangement can increase the extension length of the first air inlet hole 101 in a limited space and improve the air intake.

[0047] For example, in some embodiments, the first air inlet hole 101 includes two connected extensions, and the extension directions of the two connected extensions are arranged at an included angle.

[0048] In an application scenario, the two connected extensions are respectively a first extension 1011 and a second extension 1012, and the lowest end of the first air inlet hole 101 is located at the lowest end of the second extension 1012. The projection of the second extension 1012 in the horizontal plane is arranged at a first included angle A1 with the second direction x2.

[0049] In some embodiments, as shown in Figure 6 the extension direction of the first extension 1011 and the extension direction of the second extension 1012 are arranged at an obtuse angle.

[0050] The above arrangement can arrange more first air inlet holes 101 in a limited space and improve the air intake efficiency.

[0051] For example, as shown in Figure 6 the first extension 1011 and the second extension 1012 can also be arranged symmetrically about the first direction x1.

[0052] The above arrangement can increase the extension length of the first air inlet hole 101 in a limited space and improve the air intake through a simple structure.

[0053] In other embodiments, the first air inlet hole 101 can also include a plurality of connected extensions, and the number and respective extension directions of the extensions are not limited, as long as the lowest end of the first air inlet hole 101 is located outside the side edge of the wind blocking part 110 and the lowest end extends towards the second air inlet hole 102. This arrangement can increase the extension length of the first air inlet hole 101 in a limited space and improve the air intake.

[0054] In other embodiments, similar improvements can also be made for the fourth air inlet hole 104.

[0055] For example, the fourth air inlet hole 104 extends in a curved or zigzag manner. For another example, the first air inlet hole 101 includes a first extension part 1011 and a second extension part 1012, the extension directions of the first extension part 1011 and the second extension part 1012 are arranged at an included angle; the fourth air inlet hole 104 includes a third extension part and a fourth extension part, the third extension part and the fourth extension part are symmetrically arranged about the second direction x2. The bending direction of the first air inlet hole 101 and the fourth air inlet hole 104 is not limited, for example, the first air inlet hole 101 and the fourth air inlet hole 104 can be arranged to bend in opposite directions or to bend in opposite directions, so that the lowest ends of the first air inlet hole 101 and the fourth air inlet hole 104 are away from the first sub air blocking part 1101, that is, located outside the side of the first sub air blocking part 1101 in the horizontal direction.

[0056] In some embodiments, the second direction x2 is perpendicular to the first direction x1, that is, the arrangement direction of the projection of the first sub air blocking part 1101 and the first air inlet part 111 in the horizontal plane is perpendicular to the arrangement direction of the second air inlet part 112, the first sub air blocking part 1101 and the third air inlet part 113.

[0057] The above arrangement can optimize the overall structural layout, so that the oil stains near the first air inlet part 111 on the side close to the user can be more uniformly guided to the side away from the user. For example, in some application scenarios, this way facilitates the arrangement that the lowest end of the first air inlet hole 101 extends towards the second air inlet hole 102, or the arrangement that the lowest end of the fourth air inlet hole 104 extends towards the third air inlet hole 103.

[0058] In some embodiments, referring to Figure 4 , the hole wall of the second air inlet hole 102 is provided with a flange 114, which extends away from the hole wall into the flow guide cavity 105 of the range hood.

[0059] The above arrangement can improve the effect of the range hood. Specifically, the flange 114 extends from the outside into the flow guide cavity 105, which can reduce the wind resistance and guide the airflow into the flow guide cavity 105, thereby improving the flow guiding effect on the oil fume airflow; further, the design of the flange 114 can shield the noise inside the flow guide cavity 105, achieving a certain noise reduction effect.

[0060] In some embodiments, the extension direction of the flange 114 and the extension direction of the hole wall are arranged at a second included angle A2, the second included angle A2 is greater than or equal to 15 degrees and less than or equal to 60 degrees.

[0061] The above arrangement can better reduce wind resistance and improve the flow guiding effect of the oil fume flow to the flow guiding cavity 105. Specifically, in an application scenario, the second air inlet hole 102 is a long strip-shaped air inlet hole, and the extension direction of the folding piece 114 is arranged at a second included angle A2 with the extension direction of the hole wall. If the second included angle A2 is too large, the wind resistance will be increased, which is not conducive to the flow of the air flow into the flow guiding cavity 105; if the second included angle A2 is too small, the flow guiding effect is poor. The second included angle A2 can be 15 degrees, 18 degrees, 20 degrees, 25 degrees, 30 degrees, 33 degrees, 42 degrees, 45 degrees, 49 degrees, 50 degrees, or 60 degrees, etc.

[0062] Preferably, the second included angle A2 is 35 degrees.

[0063] In an application scenario, the fan 15 of the range hood is usually arranged directly above the flow guiding plate 11, and therefore, the second included angle A2 between the folding piece 114 and the hole wall is arranged to be 35 degrees, which can better guide the air flow to the air inlet of the fan 15 and improve the smoke suction efficiency of the range hood.

[0064] In some embodiments, similar improvements can also be made to the third air inlet hole 103. For example, the folding piece 114 described above is arranged on the hole wall of the third air inlet hole 103, and similar improvements can be made to the folding piece 114 according to the above embodiments, which will not be described here.

[0065] In other embodiments, the second air inlet hole 102 or the third air inlet hole 103 is in the shape of a hexagonal mesh, etc., and the specific shape is not limited.

[0066] In other embodiments, similar improvements can also be made to the first air inlet hole and the fourth air inlet hole. For example, the folding piece described above is arranged on the hole wall of the first air inlet hole or the fourth air inlet hole, and similar improvements can be made to the folding piece according to the above embodiments, which will not be described here.

[0067] The present application further proposes a range hood, as shown in Figures 1 to 6 The range hood includes the flow guiding plate 11 of any of the above embodiments.

[0068] The specific implementation and working principle of the flow guiding plate 11 can be referred to the above embodiments, which will not be described here.

[0069] The above arrangement can improve the air inlet efficiency of the range hood through the first air inlet part 111 and the second air inlet part 112, reduce the accumulation of oil stains at the wind blocking part 110, and guide the oil stains to the second air inlet hole 102 of the second air inlet part 112 located below the first air inlet part 111. The second air inlet hole 102 is convenient to clean, and therefore, the cleaning convenience can be improved.

[0070] In some embodiments, referring to Figure 1 , Figure 2The range hood further comprises a box body 12 and a flow guide plate 11, the flow guide plate 11 is arranged on the box body 12 and forms a flow guide cavity 105 together with the box body 12; the flow guide plate 11 comprises a flow guide box plate 21, a smoke gathering part 22 and a smoke suction part 23, the smoke gathering part 22 is arranged on the flow guide box plate 21 and recessed towards the flow guide cavity 105 to form a smoke gathering cavity, the smoke suction part 23 is arranged on the cavity bottom wall of the smoke gathering cavity and protrudes away from the flow guide cavity 105, wherein the smoke suction part 23 is provided with a wind blocking part 110 and a first air inlet part 111 and a second air inlet part 112 which are communicated with the flow guide cavity 105; the wind blocking part 110 is located below the first air inlet part 111.

[0071] The above arrangement can improve the smoke suction effect and the oil stain flow guiding effect. Specifically, the suction force in the flow guide cavity 105 is transmitted to the smoke gathering cavity through the first air inlet hole 101 and the second air inlet hole 102, so that a more stable and uniform suction force is formed in the smoke gathering cavity, which can make the airflow in the smoke gathering cavity more stable, so that the oil fume airflow entering the flow guide cavity 105 from the smoke gathering cavity is more uniform and the noise is lower, and the smoke suction performance of the range hood can be effectively improved. Further, the smoke suction part 23 is arranged on the cavity bottom wall of the smoke gathering cavity and protrudes away from the flow guide cavity 105, which can move the negative pressure area generated by the first air inlet hole 101 and the second air inlet hole 102 outward, so as to be closer to the source of oil fume, and a stronger suction force can be generated on the oil fume, which is beneficial to the gathering of oil fume to the smoke gathering cavity, so that the oil fume can be better sucked away, and the smoke suction performance of the range hood can be further improved.

[0072] In some embodiments, the flow guide plate 11 is an integrally formed structure, which can improve the assembly convenience.

[0073] In some embodiments, the range hood further comprises a condensation plate 13 arranged at least directly below the second air inlet hole 102.

[0074] Specifically, the oil fume enters the flow guide cavity 105 through the condensation plate 13 and the first air inlet hole 101 and the second air inlet hole 102.

[0075] The above arrangement can improve the user experience. Specifically, the condensation plate 13 is arranged directly below the second air inlet hole 102, which can prevent the oil stains in the flow guide cavity 105 from dripping to the outside of the range hood through the second air inlet hole 102 of the second air inlet part 112, and the condensation plate 13 is easy to clean, which can improve the cleaning convenience; further, the arrangement of the wind blocking part 110 and the first air inlet hole 101 can make the oil stains at the first air inlet part 111 flow to the area where the second air inlet hole 102 is located. Therefore, the design of the present embodiment can improve the overall appearance of the range hood as a whole, reduce the oil stains in the flow guide cavity 105 from dripping to the area outside the range hood such as the cooking bench through the first air inlet hole 101 or the second air inlet hole 102, and improve the user experience.

[0076] In some embodiments, the projection of the second air inlet hole 102 in the direction of gravity is entirely located within the projection of the condensing plate 13 in the direction of gravity, which can prevent oil dirt in the flow guide cavity 105 from dripping out of the extractor hood through the second air inlet hole 102 of the second air inlet portion 112.

[0077] In some embodiments, the extractor hood includes at least two condensing plates 13, and the flow guide plate 11 further includes a third air inlet portion 113 provided with a third air inlet hole 103; one condensing plate 13 is arranged directly below the second air inlet hole 102, and the other condensing plate 13 is arranged directly below the third air inlet hole 103.

[0078] In some embodiments, the projection of the third air inlet hole 103 in the direction of gravity is entirely located within the projection of the corresponding condensing plate 13 in the direction of gravity.

[0079] In some embodiments, the third air inlet hole 103 is symmetrically arranged with the second air inlet hole 102, and the corresponding two condensing plates 13 are symmetrically arranged.

[0080] In some embodiments, referring to Figure 1 , Figure 2 , the extractor hood includes a box body 12, a frame 14, a fan 15, a flow guide plate 11, and a flange; the box body 12 includes a box top plate, which surrounds the flow guide plate 11 to form a flow guide cavity 105; the flange is used to connect the frame 14 and the flow guide plate 11; the frame 14 is fixedly installed above the box body 12, and the fan 15 is arranged in an air duct cavity formed by the frame 14; the flange and the flow guide plate 11 form a sub-flow guide cavity, and the connection part of the flange and the flow guide plate 11 is arranged around the first air inlet portion 111, the second air inlet portion 112, and the third air inlet portion 113.
