Detailed Implementation

[0018] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0020] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0022] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone.

For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0023] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0024] like Figure 1-4 As shown in the figure, this disclosure provides a range hood, preferably a top-mounted range hood. The range hood includes a smoke collection hood 1, which is provided with an air inlet 10, a smoke baffle assembly, and a drive assembly. The air inlet 10 is used to draw in cooking fumes, which enter the range hood through the air inlet 10.

[0025] like Figure 2-4 As shown, the smoke baffle assembly includes multiple smoke baffles, each smoke baffle having a connecting side that is rotatably connected to the smoke collection hood 1. Specifically, the bottom surface of the smoke collection hood 1 includes a central region and an edge region. The central region is provided with an air inlet 10, and the edge region is provided with a smoke baffle assembly. The connecting side of the smoke baffle is rotatably connected to the edge region.

[0026] The drive assembly is driven to the connection side of at least one smoke baffle, such that the torque output by the drive assembly is applied to the connection side of at least one smoke baffle. The connection sides of at least two adjacent smoke baffles in the smoke baffle assembly are driven to each other, thereby enabling one smoke baffle to drive the rotation of the other.

[0027] Any one of the multiple smoke baffles in the smoke baffle assembly is connected to the drive assembly or another smoke baffle, thereby enabling the multiple smoke baffles to be opened or closed synchronously by the drive assembly. The drive assembly is used to drive the multiple smoke baffles to one of the synchronous opening and synchronous closing, thereby driving the multiple smoke baffles to switch from an open state to a closed state or from a closed state to an open state, so that the multiple smoke baffles are in one of the open state and the closed state.

[0028] The air inlet 10 of the top-mounted range hood is located above the stove. During cooking, the fumes generated splash, rise, and diffuse. The rising and diffusion of fumes prevents some of them from being drawn into the top-mounted range hood, causing them to escape. In this embodiment, the open baffle provides an additional smoke-gathering area for the range hood, increasing the negative pressure smoke-gathering area and improving the smoke extraction effect. The open baffle can cover the air inlet 10 of the range hood, thereby inhibiting the diffusion of odors from inside the range hood. At the same time, this embodiment uses a single drive component to drive the multiple baffles to open or close synchronously, ensuring the stability and synchronicity of the opening and closing states of the multiple baffles.

[0029] In an optional embodiment, the smoke baffle assembly includes a first smoke baffle group and a second smoke baffle group. The first smoke baffle group includes two smoke baffles disposed opposite to each other. When the two smoke baffles in the first smoke baffle group are in the open state, they each have a first opening angle. When the two smoke baffles in the second smoke baffle group are in the open state, they each have a second opening angle. The first opening angle and the second opening angle may be the same as or different from each other.

[0030] For example, the two smoke baffles in the first smoke baffle group are two smoke baffles respectively set on the left and right sides of the smoke collection hood 1 of the range hood. The two smoke baffles are set along the side edges of the left and right sides of the smoke collection hood 1 of the range hood. The side edges of the left and right sides of the smoke collection hood 1 can be short side edges, and the two smoke baffles have a shorter length accordingly. When the two smoke baffles are in the open state, they each have a first opening angle.

[0031] The two smoke baffles in the second smoke baffle group are two smoke baffles respectively set on the front and rear sides of the smoke collection hood 1 of the range hood. The two smoke baffles are set along the sides of the front and rear sides of the smoke collection hood 1 of the range hood. The sides of the front and rear sides of the smoke collection hood 1 can be long sides, and the two smoke baffles have a relatively long length. When the two smoke baffles are in the open state, they each have a second opening angle.

[0032] Optionally, the first opening angle may be the same as or different from the second opening angle. Optionally, the first opening angle may be greater than the second opening angle, thereby ensuring that the two smoke baffles in the first smoke baffle group can provide a larger additional smoke collection area for the range hood, while providing an additional smoke collection area for the range hood through the two smoke baffles in the second smoke baffle group, and avoiding interference with the user by the smoke baffles.

[0033] In an alternative example, the two smoke baffles in the first smoke baffle group each have a first opening angle when in the open state, and the two smoke baffles in the second smoke baffle group have different opening angles when in the open state. Specifically, the two smoke baffles in the second smoke baffle group are a front smoke baffle disposed on the front side of the range hood smoke collection hood 1 and a rear smoke baffle disposed on the rear side of the range hood smoke collection hood 1, and the opening angle of the front smoke baffle when in the open state is equal to or greater than the opening angle of the rear smoke baffle when in the open state.

[0034] In one optional embodiment, any two adjacent smoke baffles in the transmission connection are connected by helical gear meshing on their connecting sides. Specifically, for the two adjacent smoke baffles in the transmission connection, the connecting side of one of the two smoke baffles has an end closer to the other, and this end is provided with a helical gear. The two smoke baffles are connected by helical gear meshing. Thus, stable transmission and synchronous opening and closing between any two adjacent smoke baffles in the transmission connection are achieved through helical gear meshing connection.

[0035] In an optional embodiment, for any two adjacent smoke baffles in the transmission connection, two helical gears meshing on the two smoke baffles have the same or different number of teeth. The two helical gears are respectively connected to one of the two smoke baffles. Thus, the two smoke baffles are made to rotate synchronously at the same or different speeds through the two helical gears, so that the two smoke baffles have the same or different opening angles when they are in the open state.

[0036] In one optional embodiment, the drive assembly includes a drive motor 21 and a first bevel gear 22, wherein the first bevel gear 22 is directly connected to or driven by the output shaft of the drive motor 21. Specifically, the first bevel gear 22 is fixedly mounted on the output shaft of the drive motor 21, or the output shaft of the drive motor 21 is driven by the first bevel gear 22 through a transmission mechanism.

[0037] The smoke baffle assembly includes a first smoke baffle 11, and a second bevel gear 111 is provided at one end of the connecting side of the first smoke baffle 11. The second bevel gear 111 meshes with the first bevel gear 22. Thus, the drive assembly can drive the first smoke baffle 11 to rotate via the first bevel gear 22.

[0038] In one optional embodiment, the smoke baffle assembly comprises a first smoke baffle 11, a second smoke baffle 12, a third smoke baffle 13, and a fourth smoke baffle 14. The first smoke baffle 11 and the third smoke baffle 13 are disposed opposite to each other, and the second smoke baffle 12 and the fourth smoke baffle 14 are disposed opposite to each other, with the second smoke baffle 12 and the fourth smoke baffle 14 located at opposite ends of the first smoke baffle 11.

[0039] Optionally, the first smoke baffle 11 and the third smoke baffle 13 constitute one of the first smoke baffle group and the second smoke baffle group, and the second smoke baffle 12 and the fourth smoke baffle 14 constitute the other of the first smoke baffle group and the second smoke baffle group.

[0040] The first smoke baffle 11 is driven to the second smoke baffle 12, and the first smoke baffle 11 is driven to the fourth smoke baffle 14. The second smoke baffle 12 or the fourth smoke baffle 14 is driven to the third smoke baffle 13. Thus, the first smoke baffle 11, the second smoke baffle 12, the third smoke baffle 13, and the fourth smoke baffle 14 are driven to rotate synchronously directly or indirectly by the drive assembly.

[0041] In an optional embodiment, a third bevel gear 112 is provided at the other end of the connecting side of the first smoke baffle 11, and the third bevel gear 112 is coaxially arranged with the second bevel gear 111.

[0042] A fourth bevel gear 121 is provided on the connecting side of the second smoke baffle 12 near the end of the first smoke baffle 11. The fourth bevel gear 121 meshes with the second bevel gear 111, thereby connecting the second smoke baffle 12 and the first smoke baffle 11 through the meshing of the fourth bevel gear 121 and the second bevel gear 111.

[0043] The fourth smoke baffle 14 is provided with a fifth bevel gear 141 at one end of the connecting side near the first smoke baffle 11. The fifth bevel gear 141 meshes with the third bevel gear 112, thereby connecting the fourth smoke baffle 14 and the first smoke baffle 11 through the meshing of the fifth bevel gear 141 and the third bevel gear 112.

[0044] In an optional embodiment, a sixth bevel gear 122 is provided at the end of the second smoke baffle 12 away from the first smoke baffle 11. The sixth bevel gear 122 meshes with a seventh bevel gear 131 at one end of the third smoke baffle 13. Thus, the second smoke baffle 12 and the third smoke baffle 13 are connected by the meshing of the sixth bevel gear 122 and the seventh bevel gear 131.

[0045] In an alternative embodiment, a sixth bevel gear is provided at the end of the fourth smoke baffle 14 away from the first smoke baffle 11 on the connecting side. The sixth bevel gear meshes with a bevel gear at one end of the third smoke baffle 13 on the connecting side. Thus, the fourth smoke baffle 14 and the third smoke baffle 13 are connected by bevel gear meshing.

[0046] In an optional embodiment, the drive assembly includes an eighth bevel gear (not shown) that is driveably connected to the output shaft of the drive motor 21. Optionally, the drive assembly includes a drive shaft (not shown) that is driveably connected to the output shaft of the drive motor 21. For example, the output shaft of the drive motor 21 is provided with a first drive gear (not shown), the drive shaft is provided with a second drive gear, the first drive gear meshes with the second drive gear, and the drive shaft is provided with the first bevel gear 22 and the eighth bevel gear.

[0047] For example, the drive shaft has a first bevel gear 22 and an eighth bevel gear at both ends, and the smoke baffle assembly includes a third smoke baffle 13 opposite to the first smoke baffle 11. The third smoke baffle 13 has a bevel gear that meshes with the eighth bevel gear, and the first bevel gear 22 meshes with a second bevel gear 111 located at one end of the first smoke baffle 11 on the connecting side. Thus, the first smoke baffle 11 and the third smoke baffle 13 are directly driven to rotate by the drive assembly.

[0048] One of the first smoke baffle 11 and the third smoke baffle 13 is connected to one of the second smoke baffle 12 and the fourth smoke baffle 14 by a helical gear meshing. The other of the first smoke baffle 11 and the third smoke baffle 13 is connected to the other of the second smoke baffle 12 and the fourth smoke baffle 14 by a helical gear meshing. The transmission connection structure between adjacent smoke baffles can adopt the aforementioned bevel gear meshing connection structure, which will not be described in detail here.

[0049] Optionally, the smoke hood 1 is equipped with a touch display panel 3 or an operation panel, which is used to receive user input. Optionally, the touch display panel 3 or the operation panel is equipped with a voice receiving component, which is used to receive user voice commands. The range hood also includes a control unit, which is used to generate control parameters based on the user's voice commands, and the control parameters are used to control the operation of the range hood.
