Description

Technical Field

[0001] This invention belongs to the field of range hood technology, and specifically relates to a range hood. Background Technology

[0002] Range hoods are an essential kitchen appliance. They use a fan to create negative pressure, drawing in cooking fumes, exhaust gases, heat, and particulate matter. After the oil mist is separated by a filter, the purified gas is either exhausted outdoors or recirculated indoors. Range hoods quickly remove cooking odors and fumes, preventing the spread of fumes that can cause grease buildup on walls, cabinets, and tableware. This reduces the risk of respiratory illnesses and skin damage, and is especially beneficial for the health of those who cook for extended periods.

[0003] To cater to modern consumers' demand for minimalist and aesthetically pleasing kitchen designs, many people now opt for top-mounted range hoods, embedding the main body of the hood within the upper cabinets for a concealed layout. However, the control panel of top-mounted range hoods is often located on the user-facing side, and since this panel cannot be hidden within the cabinet, a considerable portion of the hood still protrudes from the cabinet, preventing a completely concealed design. Furthermore, the top-mounted design means the air inlet is entirely at the bottom of the hood and doesn't extend downwards, resulting in a greater distance between the inlet and the cookware below, leading to less than ideal overall smoke extraction.

[0004] To solve the above problems, it is necessary to design a range hood that can achieve a concealed layout and has a good fume extraction effect. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a range hood that can achieve a concealed layout and has a good fume extraction effect.

[0006] The present invention provides a range hood, which includes a range hood body, an operation panel, a smoke collection plate structure and a multi-link structure. The bottom of the range hood body is provided with an air inlet. The operation panel is rotatably connected to the bottom of the range hood body. When the operation panel is closed, the operation panel covers the air inlet.

[0007] The range hood body has storage cavities on both sides, and the smoke-gathering plate structure and the multi-link structure are housed in the storage cavities. The multi-link structure is kinetically connected to the smoke-gathering plate structure, and the smoke-gathering plate structure is also rotatably connected to the range hood body. The smoke-gathering plate structure can unfold downwards relative to the storage cavities. When the control panel is opened, the control panel rotates to the front of the range hood body, and the smoke-gathering plate structure unfolds downwards and is located on both sides of the range hood body. The smoke-gathering plate structure and the control panel form a smoke-gathering cavity.

[0008] Preferably, the smoke collection plate structure includes a front smoke collection plate, a front smoke collection plate base, a rear smoke collection plate, and a rear smoke collection plate base. The front smoke collection plate base is disposed on the front side of the storage cavity and fixedly connected to the main body of the range hood. The rear smoke collection plate base is disposed on the rear side of the storage cavity and fixedly connected to the main body of the range hood.

[0009] The front smoke gathering plate and the front smoke gathering plate base are rotatably connected, and the front smoke gathering plate can rotate downward and unfold relative to the front smoke gathering plate base. The rear smoke gathering plate and the rear smoke gathering plate base are rotatably connected, and the rear smoke gathering plate can rotate downward and unfold relative to the rear smoke gathering plate base.

[0010] Preferably, the smoke collection plate structure includes a stowed state and an unfolded state;

[0011] When the smoke gathering plate structure is in the storage state: the front smoke gathering plate and the rear smoke gathering plate are stored in the storage cavity and are staggered, and the front smoke gathering plate and the rear smoke gathering plate are at least partially overlapped;

[0012] When the smoke collection plate structure is in the unfolded state: the front smoke collection plate and the rear smoke collection plate rotate downward to the bottom of the range hood body, and the front smoke collection plate and the rear smoke collection plate are arranged adjacent to each other or partially overlapped.

[0013] Preferably, the smoke collection plate structure further includes a guide assembly, which includes a first guide member, a second guide member, and a guide shaft. The guide shaft is fixedly connected to the rear smoke collection plate and protrudes relative to the rear smoke collection plate. The first guide member and the second guide member are arranged adjacent to each other and fixedly connected within the range hood body. The gap between the first guide member and the second guide member forms a guide groove. The guide shaft is movably connected within the guide groove. When the rear smoke collection plate moves, the rear smoke collection plate moves along the direction of movement of the guide shaft within the guide groove.

[0014] Preferably, the multi-link structure includes a connecting rod, a rotating rod, and a transmission rod, wherein the connecting rod is movably connected to the rotating rod, and the transmission rod is movably connected to the rotating rod;

[0015] The front end of the front smoke gathering plate is fixedly connected to the rotating rod. One end of the transmission rod is movably connected to the rotating rod, and the other end is movably connected to the rear smoke gathering plate. The rotating rod can drive the front smoke gathering plate to rotate and drive the rear smoke gathering plate to rotate synchronously through the transmission rod.

[0016] Preferably, the range hood body further includes a drive assembly, which is fixedly connected inside the range hood body. The multi-link structure further includes a drive rod, which is disposed above the connecting rod. One end of the drive rod is movably connected to the connecting rod, and the other end is fixedly connected to the drive assembly. The connecting rod is connected to the drive assembly through the drive rod.

[0017] Preferably, the multi-link structure is provided in two sets and is respectively disposed in the storage cavities on both sides of the range hood body. The two sets of multi-link structures are connected by a synchronous shaft. The two ends of the synchronous shaft are respectively fixedly connected to the rotating rods on both sides. The drive assembly is connected to one set of multi-link structures. When the drive assembly drives the rotating rod to rotate, the synchronous shaft drives the rotating rod of the other set of multi-link structures to rotate.

[0018] Preferably, the range hood further includes an elastic base plate structure, which is disposed at the bottom of the range hood body and corresponds to the storage cavity. The elastic base plate structure covers the bottom of the storage cavity and is rotatably connected to the range hood body. The elastic base plate structure can be flipped downward to expose the storage cavity.

[0019] Preferably, the elastic base plate structure includes a base plate body, a reset member, and a base plate base; at least two base plate bases are provided and fixedly connected to the range hood body, the base plate bases are movably connected to the base plate body, and the base plate body can rotate downward relative to the base plate bases;

[0020] The reset component is disposed between the base plate and the base plate body. One end of the reset component is connected to the base plate and the other end is connected to the base plate body. The reset component is used to drive the base plate body to reset after the base plate body is rotated downward.

[0021] Preferably, the range hood body includes a first sensing component, which is disposed at the bottom of the range hood body and close to the front side. The first sensing component is used to sense hand gestures to control the operating status of the range hood body.

[0022] The control panel includes a second sensing component, which is located in the middle of the control panel. The second sensing component is used to sense hand gestures to control the operating status of the range hood body.

[0023] Compared to existing technologies, the range hood proposed in this solution has at least the following beneficial effects:

[0024] 1. The range hood provided in this solution is a top-mounted range hood. A control panel that can be rotated to open or close is located at the bottom of the main body of the range hood. Downward-facing smoke-gathering plates and multi-link structures connected to these plates are located in the storage cavities on both sides. The control panel can rotate downwards from the main body of the range hood and move to the front. The smoke-gathering plates on both sides unfold downwards and form a smoke-gathering cavity with the control panel. When the range hood is closed, the control panel covers the bottom of the main body, and the smoke-gathering plates and multi-link structures are stored inside the main body, allowing the entire range hood to be embedded in the kitchen cabinet for a fully concealed layout. When the range hood is working, the control panel and smoke-gathering plates form a smoke-gathering cavity, improving the efficiency of smoke extraction. Attached Figure Description

Detailed Implementation

[0046] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0047] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0048] For aesthetic reasons, more and more consumers are choosing top-mounted range hoods and embedding the main body of the hood into kitchen cabinets, concealing both the exhaust pipe and the hood itself. However, traditional top-mounted range hoods have a fixed control panel on the user-facing side for operation. Therefore, even when the main body is hidden in the cabinet, the control panel still needs to be partially exposed below the cabinet, preventing a completely concealed layout. Furthermore, top-mounted range hoods are relatively far from cookware and stoves, allowing fumes to escape without being drawn in. To address this, the applicant has developed a new type of top-mounted range hood that integrates a movable control panel that can be opened and closed. When closed, the control panel retracts to the bottom of the range hood, flush with the bottom, allowing the entire hood to be embedded in the cabinet without being visible. When the range hood is operating, the control panel moves to the front of the main body, and the smoke-collecting plate unfolds downwards, forming a smoke-collecting chamber with the control panel, improving smoke collection efficiency and making the control panel easy for the user to operate.

[0049] Please refer to Figures 1-19 This invention provides a range hood, which includes a range hood body 20, an operation panel 30, a smoke collection plate structure 10, and a multi-link structure 50. The bottom of the range hood body 20 is provided with an air inlet. The operation panel 30 is rotatably connected to the bottom of the range hood body 20. When the operation panel 30 is closed, the operation panel 30 covers the air inlet.

[0050] The range hood body 20 has storage cavities 201 on both sides. The smoke gathering plate structure 10 and the multi-link structure 50 are stored in the storage cavities 201. The multi-link structure 50 is connected to the smoke gathering plate structure 10 through a transmission. The smoke gathering plate structure 10 is also rotatably connected to the range hood body 20. The smoke gathering plate structure 10 can be unfolded downward relative to the storage cavity 201. When the operation panel 30 is opened, the operation panel 30 rotates to the front of the range hood body 20. The smoke gathering plate structure 10 unfolds downward and is located on both sides of the range hood body 20. The smoke gathering plate structure 10 and the operation panel 30 form a smoke gathering cavity.

[0051] Please refer to Figure 4 , Figures 7-12In this embodiment, the smoke-collecting plate structure 10 includes a front smoke-collecting plate 101, a front smoke-collecting plate base 114, a rear smoke-collecting plate 102, and a rear smoke-collecting plate base 105. The front smoke-collecting plate base 114 is disposed on the front side of the storage cavity 201 and fixedly connected to the range hood body 20. The rear smoke-collecting plate base 105 is disposed on the rear side of the storage cavity 201 and fixedly connected to the range hood body 20. The front smoke-collecting plate 101 and the front smoke-collecting plate base 114 are rotatably connected, and the front smoke-collecting plate 101 can rotate downward relative to the front smoke-collecting plate base 114. The rear smoke-collecting plate 102 and the rear smoke-collecting plate base 105 are rotatably connected, and the rear smoke-collecting plate 102 can rotate downward relative to the rear smoke-collecting plate base 105. It can be understood that the terms "front" and "rear" here refer to the position of the user when using the range hood. Specifically, after the range hood is installed, when the user is using it, the side closer to the user is the front side, and the side farther from the user is the rear side.

[0052] Please refer to Figure 7 In this embodiment, the rear smoke-gathering plate 102 further includes a first rotating shaft 106, and the rear smoke-gathering plate base 105 is disposed at the first end of the rear smoke-gathering plate 102. The first rotating shaft 106 passes through the rear smoke-gathering plate base 105 and the rear smoke-gathering plate 102 to movably connect the rear smoke-gathering plate base 105 and the rear smoke-gathering plate 102. The rear smoke-gathering plate 102 can rotate relative to the rear smoke-gathering plate base 105 around the first rotating shaft 106. For example, the first end of the rear smoke baffle 102 is located on the side away from the front smoke baffle 101. The rear smoke baffle base 105 is used to fix the rear smoke baffle 102 to the range hood body 20, such as the inner wall of the range hood. The first rotating shaft 106 is the rotating shaft of the rear smoke baffle 102. The first rotating shaft 106 is fixedly connected to the rear smoke baffle 102 and movably connected to the rear smoke baffle base 105. The first rotating shaft 106 can rotate around itself on the rear smoke baffle base 105, so that the rear smoke baffle 102 can rotate relative to the rear smoke baffle base 105. The rear smoke baffle base 105 is a supporting component of the rear smoke baffle 102.

[0053] Please refer to Figures 1-12 In this embodiment, the smoke collection plate structure 10 includes a stowed state and an unfolded state;

[0054] When the smoke-collecting plate structure 10 is in the retracted state: the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 are stored in the storage cavity 201 and are staggered, with the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 at least partially overlapping; it can be understood that the retracted state of the smoke-collecting plate structure 10 is the closed state of the front smoke-collecting plate 101 and the rear smoke-collecting plate 102. At this time, the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 are stacked and staggered, and the two are at least partially overlapping. This arrangement can reduce the space occupied by the smoke-collecting plate structure 10 in the retracted state; in addition, the staggered arrangement of the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 can also meet the need for avoidance between the two plates during movement. Although the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 are linked and controlled, the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 have their own movement paths. The stacked staggered arrangement can meet both the storage space requirement and the movement avoidance requirement. When applied to range hoods, the smoke collection plate structure 10 is placed vertically, so the front smoke collection plate 101 and the rear smoke collection plate 102 are also placed vertically. In this case, the stacked arrangement refers to the adjacent arrangement along the horizontal direction.

[0055] When the smoke-collecting plate structure 10 is in the unfolded state: the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 rotate downwards to below the main body 20 of the range hood, and the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 are arranged adjacently or partially overlapping. It can be understood that the downward rotation mentioned here refers to the side facing the stove or kitchen utensils after the range hood is installed being downwards. When the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 move from the retracted state to the unfolded state, the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 move downwards synchronously. When they move to the preset position, the front smoke-collecting plate 101 and the rear smoke-collecting plate 102 are located in a front-to-back side position. In this way, relative to the range hood, the unfolded smoke-collecting plate structure 10 forms a side baffle with a large area, which can prevent the smoke from escaping and collect the smoke.

[0056] Please refer to Figure 11In a preferred embodiment, the front smoke baffle 101 further includes a buffer 107, which is disposed on the front smoke baffle 101 on the side near the rear smoke baffle 102, and is located between the front smoke baffle 101 and the rear smoke baffle 102. For example, the buffer 107 may be made of elastic rubber or plastic material. The buffer 107 is disposed on the front smoke baffle 101 on the side near the rear smoke baffle 102 and located between the two. When the front smoke baffle 101 and the rear smoke baffle 102 partially overlap or move relative to each other, the buffer 107 can prevent the front smoke baffle 101 and the rear smoke baffle 102 from colliding or rubbing against each other. In particular, when the front smoke baffle 101 and the rear smoke baffle 102 are unfolded and rotated, if there is any interaction between the front smoke baffle 101 and the rear smoke baffle 102, it will cause the two to collide under the action of the driving component, which may cause damage. The buffer 107 ensures that there is a gap between the front smoke baffle 101 and the rear smoke baffle 102 to improve safety.

[0057] Please refer to Figures 10-12 In this embodiment, the smoke collection plate structure 10 further includes a guide assembly 109. The guide assembly 109 includes a first guide member 110, a second guide member 111, and a guide shaft 112. The guide shaft 112 is fixedly connected to the rear smoke collection plate 102 and protrudes relative to the rear smoke collection plate 102. The first guide member 110 and the second guide member 111 are arranged adjacently and fixedly connected within the range hood body 20. The gap between the first guide member 110 and the second guide member 111 forms a guide groove 113. The guide shaft 112 is movably connected within the guide groove 113. When the rear smoke collection plate 102 moves, the rear smoke collection plate 102 moves along the direction of movement of the guide shaft 112 within the guide groove 113. For example, the first guide member 110 and the second guide member 111 have grooves on one side facing each other. The two sides of the guide shaft 112 are respectively engaged in the grooves to ensure that the guide shaft 112 will not loosen. The first guide member 110 and the second guide member 111 are arc-shaped, and the gap between them forms a guide groove 113. This groove follows the same trajectory as the rear smoke baffle 102 when it moves from the retracted state to the unfolded state, thus guiding the movement of the rear smoke baffle 102 and ensuring that it will not loosen, shake, or become misaligned during the movement.

[0058] Please refer to Figures 6-15In this embodiment, the multi-link structure 50 includes a connecting rod 203, a rotating rod 103, and a transmission rod 104. The connecting rod 203 is movably connected to the rotating rod 103, and the transmission rod 104 is movably connected to the rotating rod 103. The front end of the front smoke baffle 101 is fixedly connected to the rotating rod 103. One end of the transmission rod 104 is movably connected to the rotating rod 103, and the other end is movably connected to the rear smoke baffle 102. The rotating rod 103 can drive the front smoke baffle 101 to rotate and drive the rear smoke baffle 102 to rotate synchronously through the transmission rod 104. The rotating rod 103 is also fixedly connected to the inner side of the operation panel 30. It can be understood that the movable connection between the connecting rod 203, the rotating rod 103, and the transmission rod 104 can adopt a relatively rotatable connector 204 such as a pivot or hinge, so that the connecting rod 203 and the rotating rod 103, and the transmission rod 104 and the rotating rod 103 can rotate relative to each other. The rotating rod 103 is the driving component for the control panel 30, the front smoke-gathering plate 101, and the rear smoke-gathering plate 102. When the rotating rod 103 rotates, it directly drives the control panel 30 and the front smoke-gathering plate 101 to rotate, and indirectly drives the rear smoke-gathering plate 102 to rotate through the transmission rod 104. During the unfolding of the smoke-gathering plate structure 10, standing on the left side of the range hood body 20, one can see that the rear smoke-gathering plate 102 rotates clockwise and the front smoke-gathering plate 101 rotates counterclockwise. When the smoke-gathering plate structure 10 and the control panel 30 are fully unfolded, the front smoke-gathering plates 101 and the rear smoke-gathering plates 102 on both sides, together with the control panel 30, form a downward-opening smoke-gathering cavity. When the range hood body 20 is installed on the wall, the front smoke-gathering plates 101 and the rear smoke-gathering plates 102 on both sides, the control panel 30, and the wall also form a smoke-gathering cavity on all four sides, resulting in excellent smoke-gathering effect.

[0059] For example, the front smoke-gathering plate 101 is fixedly connected to the second end of the rotating rod 103, the first end of the transmission rod 104 is movably connected to the middle of the rotating rod 103, and the second end of the transmission rod 104 is movably connected to the edge of the rear smoke-gathering plate 102. The movable connection between the two ends of the transmission rod 104 can be achieved by using different types of pin structures, hinge structures, etc., which can realize relative movement between the end of the transmission rod 104 and the connecting party within a certain range. The front smoke-gathering plate 101 and the rear smoke-gathering plate 102 are arranged adjacently, which can ensure that when they are opened, they form a large panel smoke baffle, thereby providing a good smoke-gathering effect.

[0060] Furthermore, the second end of the transmission rod 104 is connected to the rear smoke-gathering plate 102 on the side opposite to the rear smoke-gathering plate base 105. When the transmission rod 104 moves, it drives the rear smoke-gathering plate 102 to rotate around the first rotating shaft 106. It can be understood that when the rotation fulcrum of the rear smoke-gathering plate 102 is on the rear smoke-gathering plate base 105, setting the connection position of the transmission rod 104 and the rear smoke-gathering plate 102 on opposite sides increases the lever arm of the force exerted by the transmission rod 104 on the rear smoke-gathering plate 102, thereby reducing the force required. This means that a smaller force is needed to drive the rear smoke-gathering plate 102, and under the same force, the movement of the rear smoke-gathering plate 102 is also more stable. When the transmission rod 104 moves, for the rear smoke gathering plate 102, the connection between the transmission rod 104 and the rear smoke gathering plate 102 is the power fulcrum, and the connection between the rear smoke gathering plate 102 and the rear smoke gathering plate base 105 and the first rotating shaft 106 is the rotation fulcrum. This makes the movement trajectory of the rear smoke gathering plate 102 stable and less prone to shaking during rotation.

[0061] Please refer to Figures 13-15In a preferred embodiment, the rotating rod 103 includes a first rod portion 1031 and a second rod portion 1032, with the second rod portion 1032 fixedly connected to the first rod portion 1031. The first rod portion 1031 is hook-shaped and includes a movable end 1033 and a clearance end 1034. The movable end 1033 is used for movably connecting to an external component. The first end of the connecting rod 203 is movably connected to the second rod portion 1032, and the second end of the connecting rod 203 is used for connecting to the drive component 202. The first end of the transmission rod 104 is movably connected to the second rod portion 1032, and the second end of the transmission rod 104 is used for connecting to the smoke-collecting plate structure 10. It can be understood that the first rod portion 1031 and the second rod portion 1032 of the rotating rod 103 can be two independent components fixedly connected, or they can be two integrally formed parts. The hook-shaped first rod portion 1031 refers to its arc-shaped clearance end 1034. This clearance end 1034 can be a smooth, regular arc or an irregular arc composed of multiple arc segments. This clearance end 1034 is used to avoid collisions with other components of the range hood when the rotating rod 103 rotates, ensuring that the movement trajectory of the rotating rod 103 does not collide or interfere. The movable end 1033 of the first rod portion 1031 serves as the rotation fulcrum of the rotating rod 103, and the other external components are also relatively rotatable connections. The connecting rod 203, as the power transmission component of the rotating rod 103, has its second end connected to the drive assembly 202. This connection can be directly connected to the output shaft of the drive assembly, or it can be indirectly connected using other connecting components, such as couplings, connecting rods, etc. The transmission rod 104 serves as a driven component, with its first end connected to the rotating rod 103 and its other end connected to the smoke-collecting plate structure 10. When the rotating rod 103 rotates, the transmission rod 104 rotates passively, thereby causing the smoke-collecting plate structure 10 to open or close. In this way, through the connection of the connecting rod 203, the rotating rod 103, and the transmission rod 104, both active and driven transmission can be achieved. Compared to the connecting rod 203 assembly of traditional range hoods, the structure is simpler and does not require the design of complex transmission relationships.

[0062] Please refer to Figures 13-15 Furthermore, the rotating rod 103 structure also includes a third rod portion 1035, which is fixedly connected to the second rod portion 1032 and disposed away from the first rod portion 1031. The third rod portion 1035 is used to fixably connect the rotating rod 103 to external components. For example, the third rod portion 1035 can be an independent component fixedly connected to the second rod portion 1032, or it can be integrally formed with the second rod portion 1032. The third rod portion 1035 extends outward from the second rod portion 1032 and has multiple connection holes for fixing the third rod portion 1035 to external components. The third rod portion 1035 increases the connection space of the rotating rod 103, enabling the rotating rod 103 to be connected to multiple components.

[0063] Please refer to Figures 13-15 Furthermore, the connecting rod 203 includes an arc-shaped segment 2031 and a first connecting end 2032 and a second connecting end 2033 connected to both ends of the arc-shaped segment 2031. The opening direction of the arc-shaped segment 2031 faces the first rod portion 1031 of the rotating rod 103. The first connecting end 2032 is movably connected to the second rod portion 1032, and the second connecting end 2033 is connected to the drive assembly 202. The connecting rod 203 can rotate relative to the rotating rod 103. It can be understood that both the first connecting end 2032 and the second connecting end 2033 of the connecting rod 203 can be provided with connecting holes. After the connecting rod 203 is connected to the rotating rod 103, the connecting rod 203 and the rotating rod 103 can rotate relative to the connecting holes. The opening direction of the arc segment 2031 mentioned here refers to the concave direction of the arc shape, that is, the concave direction of the arc segment 2031 is towards the first rod portion 1031 of the rotating rod 103. The clearance end 1034 of the first rod portion 1031 is in the same direction as the arc segment 2031. When the connecting rod 203 drives the rotating rod 103 to rotate, the movement directions of the two are roughly the same. Both the arc segment 2031 and the clearance end 1034 can avoid other components inside the range hood, avoiding movement collisions and interference.

[0064] Please refer to Figures 13-15 Furthermore, the second rod portion 1032 includes a first connecting hole 1036 and a second connecting hole 1037, which are arranged opposite to each other. The rotating rod 103 also includes a movable connecting member 1038, which passes through the first connecting hole 1036 and the second connecting hole 1037 respectively and is movably connected to the first connecting end 2032 of the connecting rod 203 and the first end of the transmission rod 104 respectively. It can be understood that the opposite arrangement of the first connecting hole 1036 and the second connecting hole 1037 means that there is a certain distance between them to prevent motion interference of the movable connecting member 1038 during rotation, and the distance also facilitates the installation of the movable connecting member 1038. The movable connecting member 1038 can be a rotating, pin, or other connecting member 204.

[0065] Please refer to Figure 13Furthermore, the connecting rod 203 and the transmission rod 104 are respectively disposed on both sides of the rotating rod 103, with the connecting rod 203 disposed on the inner side of the rotating rod 103 and the transmission rod 104 disposed on the outer side of the rotating rod 103. It can be understood that the inner and outer sides mentioned here are relative to the installation of the multi-link structure 50 inside the range hood. Specifically, the side of the multi-link structure 50 facing the inside of the range hood is the inner side of the rotating rod 103, and the side facing away from the inside of the range hood is the outer side of the rotating rod 103. Distributing the connecting rod 203 and the transmission rod 104 on opposite sides of the rotating rod 103 avoids collisions between the transmission rod 104 and the connecting rod 203 during rotation; and the transmission rod 104 connects to the smoke collection plate structure 10, with its outer side facilitating connection with the smoke collection plate structure 10.

[0066] Please refer to Figures 1-8 In a preferred embodiment, the range hood further includes a lighting component 60, which is disposed on the front side of the bottom of the range hood body 20. The control panel 30 is disposed on the bottom of the range hood body 20 and located on the rear side of the lighting component 60. The movable end 1033 of the first rod portion 1031 is disposed above the lighting component 60, and the clearance end 1034 is disposed opposite to the lighting component 60. Understandably, the range hood body 20 is a top-mounted range hood, with its air inlet located at the bottom. When the range hood is closed, the control panel 30 is placed horizontally at the bottom of the range hood body 20, and the lighting component 60 is adjacent to the control panel 30 with the lighting component 60 located on the front side. The control panel 30 covers the air inlet of the range hood body 20. When the range hood is opened, the control panel 30 rotates downward from the bottom and moves to the front side of the range hood body 20. During the opening process, the control panel 30 passes under the lighting component 60. After the control panel 30 is opened, the lighting component 60 can provide lighting for the kitchen utensils or stove below the range hood body 20. During the opening of the control panel 30, the clearance end 1034 of the first rod portion 1031 of the rotating rod 103 of the multi-link structure 50 and the arc segment 2031 of the connecting rod 203 both move downward around the lighting component 60 and avoid the lighting component 60, thus ensuring the smooth movement trajectory of the multi-link structure 50.

[0067] Please refer to Figures 6-12In this embodiment, the range hood body 20 further includes a drive assembly 202, which is fixedly connected inside the range hood body 20. The multi-link structure 50 also includes a drive rod, which is disposed above the connecting rod 203. One end of the drive rod is movably connected to the connecting rod 203, and the other end is fixedly connected to the drive assembly 202. The connecting rod 203 is connected to the drive assembly 202 through the drive rod. Further, the drive assembly 202 includes a drive motor and a connector 204. The drive motor is fixedly connected to the connector 204 and is also fixedly connected to the inner wall of the range hood body 20 through the connector 204. The drive assembly 202 is disposed adjacent to one of the smoke collection plate structures 10. For example, the front smoke-collecting plate base 114 is fixedly connected to the inner wall of the range hood body 20, and the first end of the rotating rod 103 is movably connected to the front smoke-collecting plate base 114. This movable connection can be achieved through a pin, hinge, or other means. The drive motor serves as the power output source. By connecting the rotating rod 103 to the connecting rod 203, the rotating rod 103 can be driven to rotate around its first end as the fulcrum. The rotating rod 103 simultaneously drives the operation panel 30, the front smoke-collecting plate 101, and the rear smoke-collecting plate 102. This achieves a transmission structure where a single power source drives multiple components, resulting in a more rational structure. Furthermore, the connection between the drive rod and the connecting rod 203 can be achieved using a rotating shaft or a swivel pin connection. This makes the drive rod and connecting rod 203 detachable. When the multi-link structure 50 malfunctions, the multi-link structure 50 can be disassembled by pulling out the swivel pin, facilitating repair or replacement.

[0068] Please refer to Figures 11-12 In this embodiment, two sets of multi-link structures 50 are provided and respectively disposed in the receiving cavities 201 on both sides of the range hood body 20. The two sets of multi-link structures 50 are connected by a synchronous shaft 108. The two ends of the synchronous shaft 108 are fixedly connected to the rotating rods 103 on both sides. The drive assembly 202 is connected to one set of multi-link structures 50. When the drive assembly 202 drives the rotating rod 103 to rotate, the synchronous shaft 108 drives the rotating rod 103 of the other set of multi-link structures 50 to rotate. It can be understood that by driving the synchronous shaft 108, on the one hand, a single drive motor can be used to drive the smoke collection plate structures 10 on both sides, reducing the number of drive motors and the space occupied, while avoiding the synchronization control problems caused by arranging multiple motors; on the other hand, the synchronous shaft 108 has a simple and reliable structure, which reduces costs while meeting the synchronization requirements.

[0069] Please refer to Figures 1-5 , Figures 8-12 , Figures 16-19In this embodiment, the range hood also includes an elastic base plate structure 40. The elastic base plate structure 40 is disposed at the bottom of the range hood body 20 and corresponds to the storage cavity 201. The elastic base plate structure 40 covers the bottom of the storage cavity 201 and is rotatably connected to the range hood body 20. The elastic base plate structure 40 can be flipped downward to expose the storage cavity 201. The elastic base plate structure 40 includes a base plate body 401, a reset member 402, and a base plate base 403. At least two base plate bases 403 are provided and fixedly connected to the range hood body 20. The base plate base 403 is movably connected to the base plate body 401, and the base plate body 401 can rotate downward relative to the base plate base 403. The reset member 402 is disposed between the base plate base 403 and the base plate body 401. One end of the reset member 402 is connected to the base plate base 403, and the other end is connected to the base plate body 401. The reset member 402 is used to drive the base plate body 401 to reset after it rotates downward.

[0070] Understandably, the base plate 403 is used to support and connect the base plate body 401 and the range hood. Two base plate 403s are provided, positioned opposite each other at both ends of the base plate body 401 to balance the force on the base plate body 401 and ensure that the base plate body 401 is not easily damaged. Further, multiple base plate 403s can be provided; in this embodiment, three base plate 403s are provided, spaced apart and movably connected to the base plate body 401. The base plate body 401 can rotate downwards relative to the base plate 403s. Here, "downwards" refers only to the range hood; after the range hood is installed, the stove, kitchen utensils, etc., are placed below the range hood, which is in a downward direction. One side of the base plate body 401 is movably connected to the base plate 403, while the other side is an open side. The open side can be rotated downwards using the connecting side as a pivot point, i.e., opened. The reset element 402 is connected between the base plate and the base body, and is connected to both. The reset element 402 has an original state and a compressed state. In the original state, the reset element 402 is not subjected to any other external force, and the reset element 402 only supports the base body and bears the weight of the base body. At this time, the connection between the reset element 402 and the base body can keep the base body in a horizontal or slightly upward tilted position. When the base body is subjected to an external force and rotates downward, the reset element 402 is subjected to force and compressed. At this time, the external force is greater than the rebound force of the reset element 402, so that the base body remains in a downward open state and the reset element 402 remains in a compressed state. When the external force is removed, the rebound force of the reset element 402 drives the base plate 401 to reset. For example, the reset element 402 can be a hinge with a reset function, a torsion spring, or a hinge with a torsion spring structure. The elastic base plate structure 40 of this embodiment can enable the base plate body 401 to reset after being subjected to force by connecting the reset member 402 between the base plate body 401 and the base plate base 403, without the need to set up other power structures. This simplifies the structural layout of the range hood and makes the structure more reasonable and simple while achieving the function.

[0071] Driven by the drive assembly 202, the smoke-collecting plate structure 10 can rotate downward from the storage cavity 201 and unfold below the range hood body 20. When the smoke-collecting plate structure 10 rotates downward, it abuts against the bottom plate body 401 and exerts a downward force on the bottom plate body 401. At the same time, it compresses the reset member 402, causing the bottom plate body 401 to open downward on one side, thus forming an opening and closing channel for the smoke-collecting plate structure 10 to continue moving downward. When the smoke-collecting plate structure 10 is fully open, the bottom plate body 401 is continuously subjected to the force of the reset member 402, keeping the bottom plate body 401 in abutting position with the side of the smoke-collecting plate structure 10. When the smoke-collecting plate structure 10 moves to retract into the storage cavity 201 under the drive assembly 202, the abutting position between the bottom plate body 401 and the smoke-collecting plate structure 10 disappears. That is, the bottom plate body 401 is only subjected to the force of the reset member 402, which can automatically reset and close the opening and closing channel. This design ensures the synchronization of movement between the smoke-collecting plate structure 10 and the elastic base plate structure 40. Furthermore, the elastic base plate structure 40 does not require a separate power unit or linkage device to achieve synchronous movement and automatic reset. In addition, it is understandable that when the smoke-collecting plate structure 10 unfolds, the base plate body 401, under the action of the reset member 402, abuts against the side of the smoke-collecting plate structure 10. This significantly reduces the amount of oil fumes entering the range hood through the gap between the base plate body 401 and the smoke-collecting plate structure 10, especially between the opening and closing channels. This reduces oil buildup in the opening and closing channels, preventing the risk of oil dripping or leaking.

[0072] Please refer to Figures 18-19 Furthermore, the base plate body 401 is also provided with a guide portion 410 on the side facing the smoke-collecting plate structure 10. The guide portion 410 is inclined downward from the outside to the inside. When the front smoke-collecting plate 101 and / or the rear smoke-collecting plate 102 moves downward, the front smoke-collecting plate 101 and / or the rear smoke-collecting plate 102 abut against the guide portion 410 and cause the base plate body 401 to rotate outward. It can be understood that the guide portion 410 is used to contact the bottom of the smoke-collecting plate structure 10. When the smoke-collecting plate structure 10 moves downward, the front smoke-collecting plate 101 and / or the rear smoke-collecting plate 102 will abut against the guide portion 410 and thereby exert a force on the base plate body 401. Under the relative action of the guide portion 410, the base plate body 401 can rotate about the rotation axis 405 and open on one side, forming an opening and closing channel for the front smoke-collecting plate 101 and / or the rear smoke-collecting plate 102 to move downward. The outer side of the guide section 410 refers to the side away from the operation panel 30, while the inner side is the side close to the operation panel 30. The process of the bottom plate body 401 rotating downward is also the process of moving away from the operation panel 30. This ensures that the bottom plate body 401 is located on the outer side of the smoke collection plate structure 10 after it is opened, greatly reducing the possibility of oil fumes adhering to the bottom plate body 401 and the possibility of entering through the gap between the bottom plate body 401 and the smoke collection plate structure 10.

[0073] Please refer to Figures 17-19 In this preferred embodiment, the base plate 403 includes a first connecting portion 404 and a rotating shaft 405. A first end of the rotating shaft 405 is connected to the first connecting portion 404, which is adjacent to the base plate body 401. The base plate body 401 has a rotating groove 406 on one side near the base plate 403. The second end of the rotating shaft 405 is inserted into the rotating groove 406, allowing the base plate body 401 to rotate relative to the rotating shaft 405. For example, the rotating shaft 405 can be fixedly connected to the first connecting portion 404, such as being integrally formed, where the rotating shaft 405 and the first connecting portion 404 are relatively fixed. Alternatively, the rotating shaft 405 can be movably connected to the first connecting portion 404, such as the rotating shaft 405 being an independent component inserted into the first connecting portion 404, allowing the rotating shaft 405 itself to rotate relative to the first connecting portion 404. The rotating shaft 405 is movably connected to the rotating groove 406 of the base body. After the rotating shaft 405 connects the base plate 403 and the base body 401, the base body can rotate relative to the base plate 403 with the rotating shaft 405 as the axis. It can be understood that the rotating groove 406 is provided on the side of the base body near the base plate 403, so that the other side of the base body can be opened or closed.

[0074] Please refer to Figures 18-19 Furthermore, at least one of the base plates 403 is provided with a second connecting part 407. The second connecting part 407 is located on the base plate 403 and on the side away from the base plate body 401. The first end of the reset member 402 is engaged with the second connecting part 407. It can be understood that the second connecting part 407 can be located on the side of the base plate 403 opposite to the base body. The second connecting part 407 can be a single-sided open structure to facilitate the installation of the reset member 402 onto the second connecting part 407. Alternatively, it can be a through-hole structure, with the first end of the reset member 402 inserted into the second connecting part 407 to complete the connection. Meanwhile, the base plate body 401 is provided with a third connecting part 408, the position of which corresponds to the reset member 402, ensuring that the reset member 402 remains upright during installation and will not experience lateral force due to installation misalignment, thus affecting the reset effect of the reset member 402. The second end of the reset member 402 is engaged or fixedly connected to the third connecting part 408, ensuring that the second end of the reset member 402 is relatively fixed to the third connecting part 408, guaranteeing that the reset member 402 can exert force on the base plate body 401 through the third connecting part 408 during reset, thereby driving the base plate body 401 to reset. When the reset member 402 is in its original state, the reset member 402 controls the base plate body 401 to be horizontally positioned.

[0075] Please refer to Figures 18-19Furthermore, the base plate 403 also includes a fourth connecting part 411, which is adjacent to the second connecting part 407. The fourth connecting part 411 is fixedly connected to the range hood body 20 to fix the elastic base plate structure 40 and the range hood body 20. It is understood that the fourth connecting part 411 is fixedly connected to the range hood body 20, such as by welding or screws, to ensure that the base plate body 401 remains stable after repeated reciprocating movements and is not easily loosened.

[0076] Please refer to Figures 17-19 In this preferred embodiment, the reset member 402 is a torsion spring, and the base plate 403 further includes a protrusion 409, in which the middle part of the torsion spring is sleeved to support the reset member 402. It is understood that the protrusion 409 is used to connect the torsion spring and provide support, making it less likely for the torsion spring to deviate or loosen during compression and reset, thereby ensuring the stability and smooth movement of the elastic base plate structure 40.

[0077] In this embodiment, the range hood body 20 includes a first sensing component, which is located at the bottom of the range hood body 20 and near the front. The first sensing component is used to sense hand gestures to control the operating status of the range hood body 20. The control panel 30 includes a second sensing component, which is located in the middle of the control panel 30. The second sensing component is used to sense hand gestures to control the operating status of the range hood body 20. It is understood that the first sensing component is located on the side closer to the user. When the range hood is off or in standby mode, the user only needs to make a hand gesture on the side of the range hood below the user to turn it on, without needing to reach inside the range hood, making the operation more convenient. Furthermore, compared to the inside, the first sensing component closer to the outside is easier for the user to grasp when making a hand gesture, thereby improving the hand gesture recognition rate. After the user turns on the range hood using the first sensing component, the control panel 30 opens and faces the user. At this time, the user can control the operating status of the range hood through the second sensing component, such as adjusting the airflow, performing self-cleaning, and turning off the range hood. By separating the first sensing component and the second sensing component and placing them in different positions, the user can still conveniently operate the range hood regardless of its state.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
