Smoke baffle installation structure and range hood

Abstract

This utility model relates to a smoke baffle mounting structure and a range hood. The smoke baffle mounting structure includes: a side plate; a rotating shaft assembly including a connecting plate and a support column protruding from the connecting plate, the connecting plate being rotatably connected to the side plate; a smoke baffle bracket with a pre-limiting groove for engaging with the support column, the smoke baffle bracket being fixedly connected to the connecting plate; and a smoke baffle fixed to the smoke baffle bracket. By engaging the support column with the pre-limiting groove on the smoke baffle bracket, pre-limiting can be achieved between the smoke baffle bracket and the connecting plate before they are fixed. In other words, the support column assists in supporting the smoke baffle bracket and the smoke baffle, reducing the load on the operator when supporting the smoke baffle. This reduces fatigue during installation and also prevents relative slippage between the smoke baffle bracket and the connecting plate, reducing alignment difficulty and improving alignment accuracy.

Description

Technical Field

[0001] This utility model relates to the technical field of range hoods, and in particular to a smoke baffle installation structure and a range hood. Background Technology

[0002] In close-range range hoods, the baffle plate is a key component that can both cover the air intake to keep the appearance clean and unfold during cooking to guide the flow of cooking fumes.

[0003] Traditional smoke baffles are mostly fixed directly to the hinge structure with screws. During installation, they rely entirely on screw tightening. The operator needs to hold the smoke baffle with one hand and tighten the screws at the same time. This is inefficient and prone to misalignment of components due to positioning errors, resulting in insufficient ease of operation. Utility Model Content

[0004] Therefore, it is necessary to provide a smoke baffle installation structure and range hood that can optimize the assembly process and reduce the difficulty of installation, in order to address the current problem of difficult smoke baffle installation.

[0005] This application provides a smoke baffle mounting structure, including: a side plate; a rotating shaft assembly, including a connecting plate and a support column protruding from the connecting plate, wherein the connecting plate is rotatably connected to the side plate; a smoke baffle bracket, having a pre-limiting groove for engaging with the support column, wherein the smoke baffle bracket is fixedly connected to the connecting plate; and a smoke baffle, fixed on the smoke baffle bracket.

[0006] In one embodiment, the opening of the pre-limiting groove is chamfered.

[0007] In one embodiment, the bottom wall of the pre-limiting groove is arc-shaped, and the outer peripheral surface of the part of the support column that engages with the pre-limiting groove is circular, corresponding to the pre-limiting groove.

[0008] In one embodiment, the opening direction of the pre-limiting groove is perpendicular to the plane where the smoke baffle is located.

[0009] In one embodiment, the support column passes through the connecting plate and is fixedly connected to the side plate, and the connecting plate is rotatably connected to the support column.

[0010] In one embodiment, the pivot assembly further includes a base plate fixed to the side plate and a pad disposed between the base plate and the connecting plate, wherein the support column passes through the pad and is fixedly connected to the base plate.

[0011] In one embodiment, a limiting hole is provided on the base plate, and a limiting protrusion is provided at the end of the support column to cooperate with the limiting hole. The limiting protrusion is inserted into the limiting hole to restrict the support column from rotating circumferentially.

[0012] In one embodiment, a connecting rod is further included for driving the smoke baffle to rotate relative to the side plate. A connecting shaft is fixed on the smoke baffle bracket. The connecting rod is sleeved on the connecting shaft and restricted between a stepped protrusion and a limiting bolt. The stepped protrusion protrudes from the outer peripheral surface of the connecting shaft. The limiting bolt is fixed to the end of the connecting shaft. A washer located between the limiting bolt and the connecting rod is also sleeved on the connecting shaft.

[0013] In one embodiment, the outer periphery of the connecting shaft is provided with a limiting surface to restrict the circumferential rotation of the gasket.

[0014] This application also provides a range hood, including the above-described smoke baffle mounting structure.

[0015] The aforementioned smoke baffle installation structure, through the pre-limiting groove opened on the smoke baffle bracket and the locking engagement with the support column, can achieve pre-limiting of the smoke baffle bracket and the connecting plate before they are fixed. In other words, the support column assists in supporting the smoke baffle bracket and the smoke baffle, thereby reducing the load on the operator to support the smoke baffle. This reduces fatigue during the installation process and also prevents relative slippage between the smoke baffle bracket and the connecting plate, reducing alignment difficulty and improving alignment accuracy.

[0029] Please combine Figure 1 , 2 as well as Figure 3 As shown, this application provides a smoke baffle mounting structure, including: a side plate 100; a rotating shaft assembly 200, including a connecting plate 210 and a support column 220 protruding from the connecting plate 210, the connecting plate 210 being rotatably connected to the side plate 100; a smoke baffle bracket 300, having a pre-limiting groove 310 that engages with the support column 220, the smoke baffle bracket 300 being fixedly connected to the connecting plate 210; and a smoke baffle 400, fixedly mounted on the smoke baffle bracket 300.

[0030] In this application, the pre-limiting groove 310 on the smoke baffle bracket 300 is engaged with the support column 220, which enables the pre-limiting of the smoke baffle bracket 300 and the connecting plate 210 before they are fixed. In other words, the support column 220 provides auxiliary support for the smoke baffle bracket 300 and the smoke baffle 400, thereby reducing the load on the operator supporting the smoke baffle 400. This reduces fatigue during installation and also prevents relative slippage between the smoke baffle bracket 300 and the connecting plate 210, reducing alignment difficulty and improving alignment accuracy.

[0031] Specifically, during installation, the operator first engages the pre-limiting groove 310 of the smoke baffle bracket 300 with the support column 220, with the support column 220 bearing the initial load of the smoke baffle 400, thus forming a pre-limiting position. After the pre-limiting position is completed, the operator can easily adjust the alignment of the smoke baffle bracket 300 and the connecting plate 210 and perform subsequent fixing operations.

[0032] More specifically, the smoke baffle bracket 300 is L-shaped, with one side of the L-shape fixed to the smoke baffle 400 and the other side of the L-shape fixed to the connecting plate 210.

[0033] In some embodiments, the connecting plate 210 and the smoke baffle bracket 300 are fixed by bolts, welding, bonding, or other commonly used fixing methods, which will not be listed in detail here. Preferably, the connecting plate 210 and the smoke baffle bracket 300 are connected by bolts. After pre-limiting, the operator can easily adjust the alignment of the bolt holes of the smoke baffle bracket 300 and the connecting plate 210, and then tighten them with bolts.

[0034] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the opening of the pre-limiting groove 310 is chamfered; a flat or rounded corner structure is added to the edge of the opening of the pre-limiting groove 310 to form a guide slope, and the support column 220 is guided to slide quickly into the pre-limiting groove 310 by the slope to achieve the effect of automatic centering, reduce the precision requirements of hand-eye coordination during installation, and further reduce the installation difficulty.

[0035] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the bottom wall of the pre-limiting groove 310 is arc-shaped, and the outer peripheral surface of the part of the support column 220 that engages with the pre-limiting groove 310 is circular, corresponding to the pre-limiting groove 310. That is, when the smoke baffle bracket 300 and the connecting plate 210 are pre-limited but not completely fixed, the smoke baffle bracket 300 can rotate around the support column 220 so that the operator can rotate the smoke baffle bracket 300 to align with the connecting plate 210.

[0036] In addition, by rotating and adjusting the smoke baffle bracket 300 and the smoke baffle 400 to a certain angle, the smoke baffle 400 can be prevented from obstructing the operator's view, so that the operator can directly access the bolt holes of the smoke baffle bracket 300, further simplifying the installation difficulty and improving the assembly convenience.

[0037] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the opening direction of the pre-limiting groove 310 is perpendicular to the plane where the smoke baffle 400 is located.

[0038] It is understandable that when the operator rotates and adjusts the smoke baffle 400 to a near-horizontal state, the smoke baffle 400 opens to a large extent, and the operator can directly observe the bolt hole positions of the smoke baffle bracket 300. In this application, the opening direction of the pre-limiting groove 310 is set perpendicular to the plane where the smoke baffle 400 is located. That is to say, when the operator rotates and opens the smoke baffle 400 to a horizontal state, the opening direction of the pre-limiting groove 310 is exactly downward. At this time, the pre-limiting groove 310 of the smoke baffle bracket 300 automatically engages with the support column 220 and achieves pre-limiting, thereby freeing the operator's hands and facilitating subsequent bolt tightening operations.

[0039] Specifically, when the smoke baffle 400 is driven to rotate to the horizontally unfolded state, the support column 220 is fully embedded in the pre-limiting groove 310. The circumferential limit is formed by the arc-shaped structure at the bottom of the groove and the circular outer circumference of the support column 220, which reduces the risk of shaking and prevents the support column 220 from accidentally coming out.

[0040] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the support column 220 passes through the connecting plate 210 and is fixedly connected to the side plate 100, and the connecting plate 210 is rotatably connected to the support column 220.

[0041] It is understandable that the rotating shaft assembly 200 needs to simultaneously achieve a stable connection between the support column 220 and the side plate 100 and a flexible rotation of the connecting plate 210, so as to prevent the smoke baffle 400 from shaking after installation due to the loosening of the support column 220 or the connecting plate 210.

[0042] In this application, the support column 220 adopts a stepped shaft structure, including a rotating shaft part 222 and a support part 223. The rotating shaft part 222 is rotatably connected to the connecting plate 210, and one end is fixed to the side plate 100, while the other end is fixed to the support part 223. The diameter of the support part 223 is larger than that of the rotating shaft part 222 and is used to engage with the pre-limiting groove 310. This allows the connecting plate 210 to rotate freely around the rotating shaft part 222, while the support part 223 restricts the axial displacement of the connecting plate 210 and prevents it from shifting axially.

[0043] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the pivot assembly 200 further includes a base plate 230 fixed to the side plate 100 and a pad 240 disposed between the base plate 230 and the connecting plate 210, and the support column 220 passes through the pad 240 and is fixedly connected to the base plate 230.

[0044] The pad 240 can cooperate with the support 223 to achieve bidirectional limiting of the connecting plate 210 in the axial direction, further reducing the possibility of axial displacement. In addition, it should be understood that the distance between the connecting plate 210 and the side plate 100 can be adjusted by adjusting the height of the pad 240, thereby adjusting the distance between the smoke baffle bracket 300 and the side plate 100 to adapt to different smoke baffles 400, thereby improving the versatility of the smoke baffle installation structure of this application.

[0045] Please refer to Figure 4 As shown, in some embodiments, a limiting hole 231 is provided on the base plate 230, and a limiting protrusion 221 that cooperates with the limiting hole 231 is provided at the end of the support column 220. The limiting protrusion 221 is inserted into the limiting hole 231 to restrict the support column 220 from rotating in the circumferential direction. The limiting surface that cooperates between the limiting protrusion 221 and the limiting hole 231 can be a plane or a curved surface, as long as it can restrict the relative rotation between the two.

[0046] Of course, in some embodiments, the support column 220 can also be fixed to the side plate base plate 230 by other fixing methods such as welding and bolt connection, which will not be listed in this application.

[0047] Please combine Figure 2 , Figure 5 as well as Figure 6 As shown, in some embodiments, a connecting rod 600 is also included for driving the smoke baffle 400 to rotate relative to the side plate 100. A connecting shaft 320 is fixed on the smoke baffle bracket 300. The connecting rod 600 is sleeved on the connecting shaft 320 and is restricted between the stepped protrusion 321 and the limiting bolt 322. The stepped protrusion 321 protrudes from the outer peripheral surface of the connecting shaft 320. The limiting bolt 322 is fixed to the end of the connecting shaft 320. A washer 323 located between the limiting bolt 322 and the connecting rod 600 is also sleeved on the connecting shaft 320.

[0048] In other words, by fixing the connecting shaft 320 on the smoke baffle bracket 300, the connecting rod 600 is sleeved on the connecting shaft 320, and axial positioning is achieved by the stepped protrusion 321 and the limiting bolt 322. The gasket 323 is made of a low friction coefficient material (such as plastic) and is placed between the connecting rod 600 and the limiting bolt 322 to form a sliding pair. The stepped protrusion 321 is formed into an integral structure by machining or casting the outer peripheral surface of the connecting shaft 320. The limiting bolt 322 is fixed to the threaded hole at the end of the connecting shaft 320 by threads, ensuring that the connecting rod 600 can rotate freely in the axial direction and does not come out.

[0049] It is understandable that the gasket 323, made of a low-friction coefficient material, can effectively reduce frictional noise between the connecting rod 600 and the limit bolt 322, while the clamping structure of the stepped protrusion 321 and the limit bolt 322 simplifies the installation process (only the limit bolt 322 needs to be tightened to fix it) and avoids misalignment during assembly.

[0050] Please refer to Figure 6 As shown, in some embodiments, the outer periphery of the connecting shaft 320 is provided with a limiting surface that restricts the circumferential rotation of the gasket 323.

[0051] It should be noted that the circumferential rotation of the gasket 323 with the connecting shaft 320 will lead to increased wear, decreased lubrication performance after long-term use, and recurring abnormal noise problems. To address this, this application machines a limiting surface (such as a plane, polygonal facet, or keyway) on the outer circumference of the connecting shaft 320, and designs the inner hole of the gasket 323 to match the limiting surface (such as a D-shaped hole or a square hole), preventing the gasket 323 from rotating around the connecting shaft 320. This ensures that the contact surface between the gasket 323 and the connecting rod 600 only experiences axial sliding friction, avoiding abnormal wear and uneven lubrication distribution caused by rotational friction, and extending service life.

[0052] This application also provides a range hood, including the above-described smoke baffle mounting structure.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
