A side plate sliding storage device and a range hood having the same

Abstract

This invention discloses a side baffle sliding storage device and a range hood equipped with the device. The side baffle sliding storage device includes a first slide rail arranged along the suction surface and a second slide rail arranged at an angle to the first slide rail. One end of the side baffle body is slidably engaged with the first slide rail and can rotate relative to the first slide rail, while the other end is slidably engaged with the second slide rail and can rotate relative to the second slide rail. A drive mechanism drives the side baffle to slide along the slide rails to switch between an unfolded and stored state. The two slide rails respectively constrain the movement of both ends of the baffle, resulting in even sliding force and preventing shaking or jamming. The lateral storage structure saves vertical internal space of the range hood. After the baffle is stored, the oil fume surface is completely exposed for easy cleaning, and it does not occupy kitchen operating space when retracted. The storage device is provided on both the left and right sides of the range hood body, simultaneously blocking oil fumes from both sides to reduce overflow. The device assembly does not require significant modifications to the original structure of the range hood and is compatible with various models.

Description

Technical Field

[0002] This invention belongs to the field of home appliance technology, specifically relating to a side baffle sliding storage device and a range hood having the device. Background Technology

[0005] Existing range hoods generally have an air intake surface, an air inlet, and a fume-absorbing surface. The air intake surface is the front panel of the range hood facing the cooking area and has the air inlet; the air inlet is located on the air intake surface and is the passage for fumes to enter the range hood; the fume-absorbing surface is the side panel of the side panel facing the fumes and in direct contact with them.

[0006] Existing range hood side panels are mainly divided into three types: fixed, left-right folding, and up-down sliding storage. However, all three have significant drawbacks. The first type, the fixed side panel, is rigidly connected to the range hood body and lacks storage functionality, leaving the air intake constantly exposed. After cooking, the side panel protrudes outwards, encroaching on kitchen workspace. The second type, the left-right folding side panel, relies on hinges to fold inwards for storage. Once folded, the panel's oily surface directly contacts the range hood's air intake surface, completely obscuring it and making daily cleaning difficult. The third type, the up-down sliding storage panel, uses vertical rails for lifting and retraction. This sliding mechanism occupies a significant amount of internal space along the vertical direction, compressing the space for components such as the air duct and grease trap, thus limiting the overall structural layout. In summary, the three existing types of side baffle structures have problems such as occupying operating space, non-adjustable baffle angle, inability to clean the oil fume surface after storage, and large vertical space occupation. Summary of the Invention

[0008] The purpose of this invention is to disclose a side baffle sliding storage device and a range hood with the device. By optimizing the side baffle storage movement, the invention avoids the problems of limited cleaning and large space occupation, and features a compact structure and convenient cleaning. It achieves the purpose of balancing smoke collection effect and daily maintenance.

[0009] To achieve the above objectives, the present invention discloses a side baffle sliding storage device for a range hood, comprising a first slide rail, a second slide rail, a side baffle, and a driving mechanism. The first slide rail is arranged along the air intake surface of the range hood; the second slide rail is set at an angle to the first slide rail; one end of the side baffle body is slidably engaged with the first slide rail and can rotate relative to the first slide rail, and the other end is slidably engaged with the second slide rail and can rotate relative to the second slide rail; the driving mechanism is used to drive the side baffle body to slide along the first slide rail or the second slide rail, so that the side baffle body switches to an unfolded state or a stored state.

[0010] As an optional implementation, the second slide rail has a groove arranged along its length, and a guide member is provided in the groove to slide in cooperation with the groove. The guide member is rotatably connected to the side baffle body through a connector.

[0011] As an optional implementation, one end of the connector is fixed to the side baffle body, and the other end of the connector extends a rotating shaft toward the slide groove. The guide is sleeved on the outer periphery of the rotating shaft so that the guide can rotate relative to the rotating shaft.

[0012] As an alternative implementation, the groove wall extends inward to form a support portion for supporting the guide member.

[0013] As an optional implementation, the chute is provided with a storage position and an unfolding position. When the guide slides to the unfolding position, the side baffle body is in the unfolded state; when the guide slides to the storage position, the side baffle body is in the storage state; during the process of the guide sliding from the unfolding position to the storage position or from the storage position to the unfolding position, the side baffle body is tilted relative to the suction surface.

[0014] As an optional implementation, it also includes a traction plate, which is slidably engaged with the first slide rail so that the traction plate can slide along the first slide rail. The traction plate is hinged to the side of the side baffle body via a hinge.

[0015] As an optional implementation, the traction plate is fixedly mounted with at least one traction component connected to the drive mechanism.

[0016] As an optional implementation, the drive mechanism includes a synchronous belt and a drive motor for driving the synchronous belt to rotate. The synchronous belt is at least partially arranged along the length direction of the first slide rail, and the traction member is clamped and fixed to the synchronous belt.

[0017] In another aspect, this application also provides a range hood, including a range hood body, wherein the left and right sides of the range hood body are provided with any of the aforementioned side baffle sliding storage devices.

[0018] As an optional implementation, the sliding storage devices of the side baffles located on the left and right sides of the main body of the range hood share a common drive mechanism.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) The side baffle body, which can slide and rotate at both ends, is set by the first and second slide rails at the included angle. The side baffle body is completely stored by relying on the linkage of the two slide rails. After storage, the side baffle body moves to the outside of the air intake surface and covers the air intake, which solves the problem of the air intake being exposed and affecting the overall appearance. The oil fume surface of the side baffle can be completely exposed, which is convenient for users to wipe and clean directly. It effectively solves the problem that the oil fume surface is covered and difficult to clean after storage of existing folding baffles. At the same time, this device adopts a side sliding storage layout, which can save a lot of internal installation space in the vertical direction of the range hood compared with the up and down sliding baffle. It leaves enough space for internal components such as air ducts and oil boxes. The overall structure layout is more compact. The side baffle will not protrude outward after being fully retracted, avoiding occupying kitchen operation space and improving the cleanliness of use. The two slide rails form motion constraints on both ends of the side baffle. The force is even during the sliding process, which can reduce the phenomenon of sliding jamming and shaking. The sliding operation is smoother and it is not easy to produce abnormal noise after long-term use.

[0021] (2) Both sides of the main body of the range hood are equipped with the sliding storage device of the side baffle of this application. The two side baffles can form a complete oil fume enclosure at the same time, blocking the oil fume from spreading outward from both sides of the body in all directions. It is suitable for the use scenarios of double stove and wide stove, and improves the smoke collection effect of the whole machine. The storage devices on both sides are independent of each other. One side baffle does not affect the normal operation of the other side, and the use is more flexible. The storage device can be directly installed on the side of the main body of the range hood without significantly modifying the original sheet metal and air duct structure of the range hood. It is compatible with a variety of mainstream range hood models, and the overall modification cost is lower. Attached Figure Description

[0045] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0046] Example 1

[0047] See Figures 1 to 3 As shown, one embodiment of this application provides one specific implementation of a side baffle sliding storage device. The overall device is mainly used in a range hood. The side baffle sliding storage device includes a first slide rail 1, a second slide rail 2, a side baffle body 3, and a drive mechanism.

[0048] See Figure 1As shown, the first slide rail 1 is arranged along the suction surface 61 of the range hood, mainly used to position the side baffle body 3 in the retracted state. The second slide rail 2 is arranged at a fixed angle to the first slide rail 1, mainly used to position the side baffle body 3 in the unfolded state. In this embodiment, the first slide rail 1 and the second slide rail 2 are set at a 90° angle. In other embodiments, the angle between the first slide rail 1 and the second slide rail 2 can be adjusted to any angle within the range of 30° to 60° according to the reserved space on the side of the range hood. Specifically, it can be selectively set according to the smoke collection angle.

[0049] As an improvement, the side baffle body 3 has different assembly structures at both ends. One end of the side baffle body 3 simultaneously achieves two motion relationships: sliding engagement with the first slide rail 1 and rotation relative to the first slide rail 1. The other end of the side baffle body 3 simultaneously achieves two motion relationships: sliding engagement with the second slide rail 2 and rotation relative to the second slide rail 2. The drive mechanism can output continuous power, which drives the side baffle body 3 to slide along the first slide rail 1 or the second slide rail 2. During the sliding process on the slide rail, the side baffle body 3 can switch between two working modes: an unfolded state and a retracted state.

[0050] This embodiment adopts a combination structure in which the first slide rail 1 and the second slide rail 2 are arranged at an angle, and the two ends of the side baffle body 3 are respectively sliding and rotatable. Because it abandons the traditional single linear slide rail, fixed baffle, and folding baffle single motion constraint structure, it relies on two sets of slide rails distributed at an angle to synchronously limit the movement of the two ends of the side baffle body 3. The side baffle body 3 will not experience unidirectional force deviation during the sliding switching, unfolding and storage process. It effectively overcomes the technical problems of traditional single slide rail side baffles being subjected to force on one side and frequent shaking and jamming during the sliding process, thus achieving a smooth and impact-free sliding operation of the side baffle body 3. At the same time, the side baffle body 3 completes the complete storage action by relying on the linkage of the two slide rails. After storage, the side baffle body 3 covers the range hood's air intake surface 61 to prevent foreign objects from entering the air intake 62, and at the same time covers the air intake 62, so the oil fume situation of the air intake 62 cannot be observed from the outside. The side baffle body 3, with its oil fume surface 31 facing the fumes, is completely exposed, overcoming the shortcomings of existing folding side baffles where the oil fume surface 31 is obscured after storage, making it impossible for users to wipe and clean directly. This achieves the advantages of convenient daily cleaning and no need to disassemble the side baffle body 3. Furthermore, the entire storage device adopts a lateral sliding motion logic, unlike the traditional design where vertically lifting side baffles occupy a large amount of internal space. This significantly saves vertical installation space within the range hood, overcoming the technical drawbacks of vertical sliding rails encroaching on the space for air ducts, oil boxes, and electronic control components. This results in a more compact layout of internal components and greater freedom in the overall sheet metal design. When fully retracted, the side baffle body 3 is neatly concealed within the range hood's suction surface 61, without protruding into the kitchen work area. This overcomes the problem of fixed side baffles constantly protruding and occupying countertop space, thus improving the overall tidiness of the kitchen and reducing obstacles to cooking operations.

[0051] See Figures 4 to 8 As shown, the second slide rail 2 has a through-type slide groove 21 along its own length direction. The slide groove 21 is equipped with a guide member 22 that can slide with the inner wall of the slide groove 21. The guide member 22 is rotatably connected to the side baffle body 3 through the connector 31.

[0052] See Figure 8 As shown, the slide 21 adopts a single-groove, one-piece molded double-layer channel structure. Inside the slide 21, two sliding channels 211 are arranged in a stacked manner. The two sliding channels 211 are arranged vertically in layers and staggered horizontally. This can be understood as the left or right inner wall surfaces of the two sliding channels 211 not being on the same vertical plane. Each sliding channel 211 has a separate guide member 22.

[0053] See Figure 8As shown, the outer diameter of the guide member 22 is smaller than the width of the sliding channel 211. This size setting provides ample assembly allowance for the guide member 22, preventing it from getting stuck inside the sliding channel 211 due to machining errors. This reduces assembly difficulty and improves the assembly tolerance during mass production. Regarding the fit between the guide member 22 and the inner wall of the sliding channel 211, one guide member 22 abuts against the left inner wall of the sliding channel 211, with a clearance fit maintained between this guide member 22 and the right inner wall of the sliding channel 211. Simultaneously, another guide member 22 abuts against the right inner wall of another sliding channel 211, with a clearance fit maintained between this guide member 22 and the left inner wall of the sliding channel 211. Because of the structural design of using two sets of guide members 22 to press against the inner walls of the left and right sides of the sliding channel 211 in opposite directions, the two guide members 22 can fill and cancel the lateral gap inside the sliding channel 211 from the left and right opposite directions, completely eliminating the lateral play between the guide member 22 and the slide groove 21. This overcomes the technical defects of the traditional single-sided slider guide structure, which has lateral gaps and causes the movable plate to swing left and right and deviate during the sliding process. As a result, the guide member 22 can slide smoothly along the sliding channel 211, greatly reducing the impact noise generated by the collision between the guide member 22 and the inner wall of the slide groove 21 during the sliding process, and improving the quietness of the equipment during operation.

[0054] In some other embodiments, the single-groove double-sliding-channel 211 structure can be replaced with a double-groove 21 structure. Two parallel-distributed grooves 21 are arranged in a stacked configuration, with each groove containing only one sliding channel 211. The sliding channels 211 within the two grooves are vertically layered and horizontally staggered. Each sliding channel 211 contains a separate guide 22. Alternatively, the two grooves 21 can have identical structures, but by horizontally staggering them, the left or right inner wall surfaces of the two sliding channels 211 are not on the same vertical plane. As another optional implementation, the two slides 21 have different structures. The two slides 21 are aligned and stacked in the vertical direction, that is, the left or right side of the two slides 21 is on the same vertical plane. The positions of the sliding channels 211 of the two slides 21 are different, and the sliding channels 211 of the two slides 21 are staggered in the horizontal direction, which also ensures that the left or right inner wall of the two sliding channels 211 is not on the same vertical plane. The upper and lower double-layer slides 21 are two independent components. During assembly, the horizontal installation position of the two slides 21 can be flexibly adjusted to change the lateral offset distance between the two sliding channels 211. This can compensate for the dimensional tolerances caused by the processing of the guide component 22, avoid the problem that the guide component 22 cannot be tightly pressed against the left and right inner walls of the channel due to the manufacturing deviation of the components, and ensure that the guide component 22 assembly always has bidirectional limiting and anti-sway capability.

[0055] See Figure 6 and Figure 8 As shown, the connector 31 includes a rotating shaft 32, a mounting portion 311, and a connecting portion 312 angled to the mounting portion 311. The connecting portion 312 is a sheet metal part, which is mainly fixed to the side baffle body 3 by adhesive bonding. The rotating shaft 32 is fixedly connected to the top surface of the mounting portion 311. The connecting portion 312 extends along the length of the side baffle body 3, which can increase the contact area between it and the side baffle body 3, thereby improving the connection strength between the two. In addition to adhesive bonding, three different sheet metal connection technologies can also be used: locking, riveting, and quick-release snap-fit.

[0056] See Figure 6 and Figure 8As shown, both guide members 22 are movably sleeved on the outer periphery of the same rotating shaft 32. The two guide members 22 are separated by a bushing, allowing the guide members 22 to rotate freely relative to the connecting member 31 with the rotating shaft 32 as the center. As a preferred embodiment, each guide member 22 includes a roller body 221 and a bearing 222. The roller body 221 has an internal mounting groove, and the bearing 222 is fixedly installed inside the mounting groove of the roller body 221. The roller body 221 is entirely sleeved on the outside of the rotating shaft 32 by the bearing 222. Because the bearing 222 is located inside the roller body 221, it can isolate the direct contact between the roller body 221 and the rotating shaft 32, further reducing the coefficient of friction during the rotation of the roller body 221. This overcomes the defects of rotational jamming and increased noise caused by direct friction between the roller body 221 and the rotating shaft 32, further improving the smoothness of the roller body 221's rotation and reducing wear after long-term use. The combination structure of the rotating shaft 32 with the built-in bearing 222 and the roller body 221 converts sliding friction into rolling friction, which reduces friction loss in two ways, effectively extends the service life of the entire guide structure, and reduces abnormal noise generated during sliding.

[0057] In some other embodiments, the two guide members 22 may also be provided with independent rotation center lines. These two rotation center lines are independent and do not coincide. Viewed in the transverse direction perpendicular to the length of the sliding channel 211, the rotation center line of one guide member 22 is located to the left of the overall center line of the slide groove 21, and the rotation center line of the other guide member 22 is located to the right of the overall center line of the slide groove 21. This can be understood as the connecting member 31 having two independent rotating shafts 32, which are offset in the transverse direction perpendicular to the length of the sliding channel 211, so that the rotation center lines of the two guide members 22 are not on the same straight line along the length of the slide groove 21. Since the two guide members 22 are configured on two different rotating shafts 32, they can be placed on the same horizontal plane. Simultaneously, only one slide groove 21 needs to be provided, and only one sliding channel 211 needs to be provided within the slide groove 21. After placing the two guide members 22 on the same horizontal plane into the same sliding channel 211, the two guide members 22 are spaced apart along the length of the slide groove 21, significantly reducing the number of slide grooves 21 and sliding channels 211 and simplifying the overall profile structure. Compared to a structure using double-layer slide grooves 21 or double-layer sliding channels 211, there is no need to rely on upper and lower layered channels to achieve the arrangement of the two guide members 22, resulting in fewer profile processing steps, a smaller overall volume of the slide groove 21, and suitability for confined installation spaces within the machine body.

[0058] In other embodiments, in addition to the roller structure, the guide member 22 can also be replaced with a wear-resistant slider structure. Each slider is stationary relative to the connector 31. Each slider has a protrusion extending outward from its outer side. The direction of the protrusion extension corresponds to the sliding channel 211 where the slider is located, so that at least one slider abuts against the left inner wall of the sliding channel 211, and the other slider abuts against the right inner wall of the sliding channel 211. The slider protrusions achieve bidirectional clearance fit and limiting, and the anti-shaking effect can be achieved without a rolling structure. It is suitable for guiding small sheet metal in low-speed, low-load scenarios.

[0059] See Figure 8 As shown, as another improvement, the bottom inner wall of the sliding channel 211 extends into the channel and is formed with a support portion 23. The support portion 23 is continuously arranged along the length of the sliding channel 211. The support portion 23 is used to support the bottom of the guide member 22 and bear the downward vertical load of the guide member 22 and the outer side baffle body 3. Because the support portion 23 is integrally formed at the bottom of the sliding channel 211, the bottom of the guide member 22 is directly supported by the support portion 23, and the weight of the suspended side baffle body 3 is entirely borne by the support portion 23. This overcomes the defects of the traditional slide 21 having no bottom support structure, the side baffle body 3 having its own weight entirely borne by the side slider, and severe side wear. This disperses the force on the guide member 22, reduces the wear on the side wall of the guide member 22, improves the overall load-bearing capacity of the guide structure, and is suitable for the use of large-size and heavy-weight suspended side baffle bodies 3. In other embodiments, the support portion 23 can be separately assembled with the slide 21, and a wear-resistant component can be embedded in the bottom of the slide 21 to form a support structure. The wear-resistant component has stronger wear resistance.

[0060] As a preferred embodiment, the end face of the guide member 22 facing the support portion 23 is provided with a first rounded corner 223, and the position where the support portion 23 connects with the inner wall of the sliding channel 211 is provided with a second rounded corner 231. The arc dimension of the second rounded corner 231 matches and adapts to the first rounded corner 223. Because the bottom of the guide member 22 and the contact position of the support portion 23 both adopt a rounded transition structure, the contact between the guide member 22 and the support portion 23 is a curved surface, without sharp edges and hard contact. This overcomes the defects of large frictional resistance between flat surfaces and sharp edges, and the defects of sharp edges being prone to wear and producing abnormal noise. In this way, the frictional resistance of the guide member 22 during the sliding process is reduced, and the problems of debris and jamming caused by long-term friction of sharp edges are avoided, further reducing sliding noise and improving sliding smoothness. The rounded corners form a curved surface contact, replacing the original hard frictional contact form of sharp edges, which can reduce the debris generated by friction and maintain a low-noise and jam-free sliding effect during long-term use.

[0061] See Figure 5As shown, the slide 21 is divided into two fixed positions along its length: a storage position 24 and an unfolding position 25. When the guide member 22 slides to the unfolding position 25 inside the slide 21, the side baffle body 3 is in a fully unfolded working state; when the guide member 22 slides to the storage position 24 inside the slide 21, the side baffle body 3 is in a fully retracted state. Throughout the entire stroke of the guide member 22 sliding from the unfolding position 25 to the storage position 24, or from the storage position 24 to the unfolding position 25, the side baffle body 3 will be tilted relative to the range hood's suction surface 61. This can be understood as the slide 21 being divided into an unfolding section and a storage section, which are set at an angle to each other, forming an L-shape. The unfolding section is arranged along the unfolding direction of the side baffle body 3, and the storage section is arranged along the retracting direction of the side baffle body 3, with a rounded transition between the two sections. In practical applications, when the guide member 22 slides from the unfolding section to the storage section via a rounded transition, the side baffle body 3 simultaneously retracts inward and maintains an inclined posture, with a gap always remaining between the side baffle body 3 and the suction surface 61. When the guide member 22 has completely slid into the storage section and reached the storage position 24, the side baffle body 3 completely retracts to cover the suction surface 61, and the oil fume surface 31 is fully exposed for easy cleaning. It should be noted that, due to the presence of the first slide rail 1 and the second slide rail 2, the side baffle body 3 and the suction surface 61 of the range hood body 6 can be in a clearance fit. This avoids the side baffle body 3 from contacting the suction surface 61 of the range hood body 6 during storage, thus preventing problems such as abnormal noise.

[0062] See Figures 1 to 3 As shown, the side baffle sliding storage device is also equipped with a traction plate 4. The traction plate 4 and the first slide rail 1 form a sliding engagement relationship. The traction plate 4 can slide freely along the length direction of the first slide rail 1. The side of the traction plate 4 near the side baffle body 3 is hinged to the side baffle body 3 through a hinge 41, thereby realizing that the side baffle body 3 can slide and rotate relative to the first slide rail 1. The auxiliary transmission structure of adding a traction plate 4 and hinged to the side baffle body 3 allows the traction plate 4 to slide independently along the first slide rail 1 and share the sliding load at the end of the side baffle body 3. This achieves that both ends of the side baffle body 3 are synchronously pulled and stressed by the traction plate 4 and the guide member 22, respectively, and the forces on both sides are balanced. This overcomes the defects of relying only on the second slide rail 2 for unilateral traction, asynchronous sliding at both ends of the side baffle body 3, and movement deviation. The hinge 41 allows for angle changes between the traction plate 4 and the side baffle body 3, adapting to the tilted movement trajectory of the side baffle body 3 throughout its sliding process, and will not constrain or interfere with the tilting movement of the side baffle body 3.

[0063] See appendix Figures 9 to 11As shown, at least one traction component 42 is fixedly mounted on the traction plate 4. The first slide rail 1 is provided with a sliding block 11 that slides with the first slide rail 1. The cross-sectional shape of the first slide rail 1 is U-shaped. The sliding block 11 is fixedly connected to the traction component 42, so that the traction component 42 can slide along the first slide rail 1. It should be noted that the first slide rail 1 and the sliding block 11 are conventional sliding mechanisms on the market. The first slide rail 1 is provided with a groove, and the sliding block 11 is placed in the groove, so as to realize the sliding cooperation between the two. The smoothness of sliding can also be improved by adding ball bearings or changing the materials of the two.

[0064] The traction component 42 is mainly used to establish a power connection directly with the drive mechanism of the entire device. As a preferred embodiment, the traction plate 4 has two traction components 42 arranged vertically at intervals. A snap-fit ​​plate 43 is fixedly installed on the end face of the traction plate 4 facing the inner cavity of the main body 6 of the smoke machine via adhesive bonding. One traction component 42 is fixedly connected to each of the upper and lower ends of the snap-fit ​​plate 43. The traction component 42 and the snap-fit ​​plate 43 are preferably connected by snap-fit ​​fastening, but other methods such as threaded fastener connection or adhesive bonding can also be used for the connection. There are also two first slide rails 1, arranged vertically at intervals on the main body 6 of the smoke machine. The vertically and vertically separated structure of the two traction components 42 can disperse the driving force borne by the traction plate 4, avoiding localized stress concentration and deformation of the traction plate 4 caused by single-point traction. Simultaneously, the synchronous pulling at both points ensures that the traction plate 4 slides smoothly and horizontally along the first slide rail 1, preventing problems such as one-sided lifting or jamming of the slide rail. It should be noted that the specific structural form of the traction component 42 can be selectively adjusted according to the drive mechanism.

[0065] exist Figures 9 to 11 In the embodiment shown, the drive mechanism includes a synchronous belt 51 and a drive motor 52. The drive motor 52 outputs torque to drive the synchronous belt 51 to rotate continuously. At least one section of the synchronous belt 51 is arranged parallel to the length of the first slide rail 1. The traction member 42 is provided with a clamping part 421, which clamps and fixes itself on the synchronous belt 51. The traction member 42 and the traction plate 4 slide synchronously by the movement of the synchronous belt 51.

[0066] See appendix Figures 9 to 11 As shown, the drive motor 52 is fixed at the lower left corner of the main body 6 of the range hood. The installation position of the drive motor 52 can be selectively set according to actual needs, as long as it can drive the synchronous belt 51 to rotate. The synchronous belt 51 is arranged in a U-shape, which is mainly suitable for situations where two sets of side baffle bodies 3 share a single drive mechanism. In some other embodiments, the synchronous belt 51 can be arranged along the length of only one of the first slide rails 1.

[0067] In other embodiments, the drive mechanism transmission assembly can be replaced with a lead screw drive assembly or a rack and pinion drive assembly. The lead screw drive outputs greater thrust and is suitable for the thickened and heavy-duty side baffle body 3; the rack and pinion drive has a faster response speed and is suitable for the ultra-thin body and short stroke side baffle body 3. Both replacement schemes can achieve the basic function of the traction component 42 driving the traction plate 4 to slide back and forth along the first slide rail 1. The transmission scheme of the synchronous belt 51 and the drive motor 52 has the characteristics of low operating noise and precise transmission displacement. It can accurately control the sliding stroke of the side baffle body 3 and overcome the defects of high noise and positioning deviation of the gear and lead screw drive. The layout of the synchronous belt 51 along the first slide rail 1 can make full use of the idle space on the side of the slide rail, without the need for an additional independent transmission compartment, further reducing the lateral space occupied by the entire device. The traction component 42, which is clamped and fixed by the clamping part 421, is easy to disassemble and assemble, which facilitates the maintenance and replacement of the transmission components in the later stage.

[0068] The overall usage process of the complete device in this embodiment is as follows: When the device is in standby idle condition, the drive motor 52 controls the synchronous belt 51 to stay in the initial position, and the traction component 42 follows the synchronous belt 51 to stay at one end of the first slide rail 1 near the inner side of the body. The traction plate 4 drives one end of the side baffle body 3 to slide to the receiving position 24 of the slide groove 21. The guide component 22 stays in the receiving position 24 of the slide groove 21. The side baffle body 3 completely covers the air intake surface 61 and air intake 62 of the smoke machine. A gap can be reserved between the side baffle body 3 and the air intake surface 61. The side baffle body 3's outer surface 31 is fully exposed, allowing users to directly wipe away grease. When the user starts the cooking mode, the drive motor 52 rotates forward, driving the synchronous belt 51 to circulate. The synchronous belt 51 pulls the traction component 42 outward along the first slide rail 1. The traction plate 4 pulls one end of the side baffle body 3 outward synchronously via the hinge 41. The other end of the side baffle body 3 slides synchronously inside the slide groove 21 of the second slide rail 2, relying on the guide component 22. The guide component 22 moves at a constant speed along the unfolded section of the slide groove 21. During the sliding process, the upper... The two sets of guide members 22 press against the inner walls of the sliding channel 211 in opposite directions to eliminate lateral swaying gaps. The first rounded corner 223 at the bottom of the guide member 22 fits against the second rounded corner 231 of the support part 23, allowing for smooth rolling without jamming or impact noise. Constrained by the angle between the first slide rail 1 and the second slide rail 2, the side baffle body 3 maintains an inclined posture relative to the suction surface 61 throughout the entire process until the guide member 22 reaches the unfolded position 25 of the slide groove 21. At this point, the drive motor 52 locks and stops, and the side baffle body 3 fully unfolds, forming a complete structure on the left and right sides of the suction surface 61 of the range hood. The entire fume enclosure confines the cooking fumes to the negative pressure zone of the fan, preventing them from escaping laterally and polluting the cabinet walls. After cooking, the user issues a storage command, driving motor 52 rotates in reverse, and synchronous belt 51 moves traction component 42 back towards the inside of the machine. Traction plate 4 pulls the side baffle body 3 inward, and guide component 22 slides along the rounded transition section of slide groove 21 to the storage section and reaches the storage position 24. The side baffle body 3 retracts and fits against the suction surface 61, and the fume surface 31 is completely exposed again, returning the equipment to the standby storage state. The entire process of unfolding and retracting the side baffle body 3 relies on the linkage of double-angle slide rails, ensuring balanced sliding force without unilateral deviation. The guide component 22 component has bidirectional limiting to eliminate lateral play, and the bottom support part 23 shares the vertical weight. The rounded contact reduces friction noise, and the storage state does not obstruct the cleaning surface. Lateral sliding saves vertical space of the machine body, and it is not prone to wear, deformation, or abnormal noise with long-term use.

[0069] Another aspect of this application provides a specific implementation method for a range hood, see below. Figures 12 to 13 As shown, the range hood body 6 includes a set of side baffle sliding storage devices described above, which are independently installed on the left and right sides of the range hood body 6.

[0070] See Figure 12 and Figure 13In the embodiment shown, the two sets of side baffle sliding storage devices on the left and right sides of the main body 6 of the range hood share the same drive mechanism to achieve power supply.

[0071] See Figures 9 to 11 As shown, the synchronous belt 51 is arranged in a U-shape. There are two first slide rails 1, which are arranged vertically at intervals and located inside the upper and lower ends of the traction plate 4. The U-shaped synchronous belt 51 has two transverse sections, which are arranged in the same direction as the corresponding first slide rails 1. The traction component 42 of the left side baffle body 3 and the traction component 42 of the right side baffle body 3 respectively clamp the forward drive section 512 and the reverse drive section 512 of the synchronous belt 51. Thus, under the drive of the same synchronous belt 51, the left side baffle body 3 and the right side baffle body 3 can move synchronously to the outside of the body to unfold, or move synchronously to the inside of the body to retract. The synchronous movement of the two side baffle bodies 3 can be completed by a single drive motor 52, overcoming the defects of more parts, complicated wiring and high cost caused by two separate independent transmission mechanisms on the left and right. The upper and lower double-layer first slide rail 1 synchronously limits the upper and lower ends of the traction plate 4 to prevent the traction plate 4 from tilting up due to force on one side and jamming the slide rail, ensuring that the traction plate 4 slides horizontally and smoothly throughout the entire process.

[0072] See Figures 9 to 11 As shown, in addition, the sliding storage devices of the left and right side baffles of the range hood can share a single extended first slide rail 1. The extended first slide rail 1 spans the width of the entire range hood body 6. The left and right traction plates 4 are slidably assembled on the same extended first slide rail 1, reducing the amount of slide rail profile used, simplifying the sheet metal opening process of the range hood, and further reducing the overall assembly cost.

[0073] The design of the whole machine, which uses a single drive mechanism for both left and right storage devices, requires only one drive motor 52 and one set of synchronous belt 51 transmission components to synchronously drive the traction components 42 and traction plates 4 on both sides of the machine body to slide synchronously. This overcomes the defects of having two separate drive motors 52 for the left and right devices, which would result in a large number of parts, complex internal wiring, and increased production costs. It significantly reduces the number of drive motors 52, control lines, synchronous belts 51 and other transmission components, simplifies the internal electrical control wiring layout of the smoke machine, and reduces the material cost and assembly time of the whole machine. The single drive mechanism uniformly controls the synchronous unfolding and retraction of the side baffle bodies 3 on both sides. The sliding displacement and unfolding range of the side baffle bodies 3 on both sides are completely consistent, and the appearance of the two sides of the whole machine is symmetrical and beautiful. This overcomes the appearance defects of asynchronous sliding and inconsistent unfolding widths when the two side baffle bodies 3 are driven by two motors respectively. At the same time, the single drive unified control logic is simpler. The smoke machine main control board does not need to output two drive control signals separately, which simplifies the development difficulty of the electrical control program and reduces the probability of electrical control failure of the whole machine.

[0074] Example 2

[0075] This invention provides a second specific embodiment of a side baffle sliding storage device. This embodiment shares the same main technical solution as Embodiment 1. Technical features not described in this embodiment are explained using Embodiment 1 and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the left and right sets of side baffle sliding storage devices are independent of each other and can be controlled and independently complete the unfolding and storage actions of the side baffle body 3. That is, the main body 6 of the range hood has two driving mechanisms that drive the corresponding side baffle body 3 to be unfolded or stored. The two driving mechanisms are independent of each other and do not operate in conjunction.

[0076] The overall layout features two independent drive and control units for the left and right storage devices. Because each storage device is equipped with an independent drive motor 52 and synchronous belt 51 transmission assembly, the unfolding and folding of one side baffle body 3 will not interfere with the movement of the other side baffle body 3. Users can fold the corresponding side baffle body 3 separately according to their cooking needs, without the need for simultaneous folding on both sides, making it more flexible to use.

[0077] Example 3

[0078] This invention provides a third specific embodiment of a side baffle sliding storage device. This embodiment shares the same main technical solution as Embodiment 1. Technical features not described in this embodiment are explained using Embodiment 1 and will not be repeated here. The difference between this embodiment and Embodiment 1 is: (See attached...) Figure 14 As shown, the U-shaped synchronous belt 51 used for synchronous driving of the double-sided side baffle body 3 in Embodiment 1 can be replaced with a through-type long synchronous belt 51.

[0079] This can be understood as follows: the through-type long synchronous belt 51 runs horizontally through the sliding path of the left and right traction plates 4 along the entire body of the tobacco machine 6. The traction component 42 of the left side baffle body 3 and the traction component 42 of the right side baffle body 3 are respectively clamped and fixed to the forward drive section 512 and the reverse drive section 512 with opposite directions of movement of the through-type long synchronous belt 51. Relying on the forward and reverse rotation of a single drive motor 52, the left and right traction components 42 can be driven to slide synchronously towards and away from each other, so as to realize the synchronous storage and synchronous unfolding of the double side baffle bodies 3.

[0080] The transmission structure adopts a through-type long synchronous belt 51 instead of a U-shaped synchronous belt 51 because the integral long synchronous belt 51 does not require the U-shaped reversing arc sections at both ends, reducing the bending fatigue loss of the synchronous belt 51 and extending its service life. At the same time, the through-type synchronous belt 51 only requires two sets of limit guide wheels to complete the trajectory constraint. Compared with the multiple sets of reversing wheels of the U-shaped synchronous belt 51, it simplifies the number of transmission parts and reduces the overall assembly cost. The synchronous belt 51 is laid out in an integral manner, which allows for a wider range of transmission stroke adjustment and can be adapted to the body of the smoke machine 6 with different widths.

[0081] Example 4

[0082] This invention provides a fourth specific embodiment of a side baffle sliding storage device. The main technical solutions of this embodiment are the same as those of embodiment 1. Technical features not described in this embodiment are explained using embodiment 1 and will not be repeated here. The difference between this embodiment and embodiment 1 is that the traction plate 4 is removed, and the two ends of the side baffle body 3 are directly slidably and rotatably connected to the first slide rail 1 and the second slide rail 2, respectively.

[0083] This embodiment omits the entire hinged transmission structure of the traction plate 4 and hinge 41. One end of the side baffle body 3 directly slides and rotates relative to the first slide rail 1. Specifically, refer to the connection structure between the second slide rail 2 and the side baffle body 3. The other end of the side baffle body 3 slides and engages with the slide groove 21 of the second slide rail 2 through the guide member 22 and the connecting member 31. The drive mechanism directly pulls the side baffle body 3 along the slide rail to complete the unfolding and retraction switching. This structure eliminates the intermediate hinged transmission pair, which on the one hand reduces the number of parts in the whole machine, simplifies the sheet metal opening and assembly process of the smoke machine, and reduces the overall production cost; on the other hand, it eliminates the shaking and abnormal noise problems caused by the rotation gap of the hinge 41, and further improves the sliding stability of the side baffle body 3. The technical means disclosed in this invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those skilled in the art, many improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the scope of protection of this invention.
