Description

Technical Field

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

[0002] A range hood is a kitchen appliance used to purify the kitchen environment. A range hood generally includes a casing and a baffle plate rotatably mounted on the casing, capable of opening and closing the air inlet. The back of the baffle plate has a baffle plate bracket for connecting to a moving mechanism. The flange of the baffle plate bracket is connected to the rocker arm of the moving mechanism by screws, typically driven from the inside out. Such a baffle plate installation structure is disclosed in patent application CN201810960800.6 (application publication number: CN110857788A), entitled "Opening and Closing Mechanism of Baffle Plate for Range Hood."

[0003] However, the smoke baffle installation structure of the range hood in the aforementioned application still has certain shortcomings. The screw holes on the flange of the smoke baffle bracket are close to the smoke baffle itself. When installing screws, the electric screwdriver interferes with the smoke baffle, making it difficult to align the screw holes perpendicularly. This is time-consuming and labor-intensive during production line assembly, becoming a bottleneck process. If the screws are forced in at an inverted angle, the connection strength cannot be guaranteed, and loosening is likely to occur later. On the other hand, when workers are screwing in screws, they must lift the smoke baffle with one hand, which, considering the length and weight of the smoke baffle, further increases the difficulty of aligning the holes. Otherwise, specialized tooling needs to be designed during production to ensure that the smoke baffle is positioned correctly in the mounting holes during installation.

[0004] Therefore, the existing smoke baffle installation structure and the range hood itself still need further improvement. Utility Model Content

[0030] Figures 1-6This invention illustrates the smoke baffle mounting structure of a range hood and a preferred embodiment of the range hood. The range hood includes a housing 1 and a centrifugal fan housed within the housing 1. The housing 1 generally includes a fan frame 11 and a smoke collection hood 12 located at the bottom of the fan frame 11. The inner cavity of the fan frame 11 communicates with the inner cavity of the smoke collection hood 12. An air inlet is provided on the front side wall of the smoke collection hood 12, allowing external fumes to enter the hood 12. The centrifugal fan, located within the fan frame 11, generates negative pressure during operation, drawing external fumes into the smoke collection hood 12 through the air inlet. An oil filter is also provided at the air inlet of the smoke collection hood 12 for filtering fumes. An oil cup 14, extending horizontally, is located at the bottom of the smoke collection hood 12 to collect oil flowing down from it.

[0031] The front of the smoke hood 12 is also provided with a smoke baffle 13 that can deflect back and forth relative to the smoke hood 12. The smoke baffle 13 is connected to the main body of the smoke hood 12 through a motion mechanism. Specifically, it can deflect forward to open the air inlet and deflect backward to block and close the air inlet. The motion mechanism includes a drive component 21, a transmission assembly, and a rocker arm 25. The transmission assembly is connected between the power output end of the drive component 21 and the rocker arm 25. The bottom of the top plate of the smoke hood 12 is provided with a connecting frame 121. The first end of the rocker arm 25 is rotatably connected to the connecting frame 121 through a third pin 263 extending left and right, and the second end is connected to the back of the smoke baffle 13. The drive component 21 is preferably a drive motor. A fixing frame 20 fixed relative to the housing 1 is provided inside the housing 1, and the drive motor is mounted on the fixing frame 20. The transmission assembly includes a crank 23 and a connecting rod 24. One end of the crank 23 is connected to the output shaft of the drive member 21 and is driven to rotate by the drive member 21. The other end of the crank 23 is rotatably connected to one end of the connecting rod 24 through a first pin 261 extending to the left and right. The other end of the connecting rod 24 is rotatably connected to the rocker arm 25 through a second pin 262 extending to the left and right.

[0032] See Figure 4 In this embodiment, there are two rocker arms 25 arranged at a left-right interval. There are two connecting brackets 121 on the left and right sides of the top plate of the housing 1. The first ends of the two rocker arms 25 are rotatably connected to the two connecting brackets 121 respectively, and the second ends of the two rocker arms 25 are connected to the left and right ends of the back of the smoke baffle 13 respectively. Among them, the left rocker arm 25 is connected to the aforementioned drive motor and transmission assembly as the driving end, while the right rocker arm 25 does not need to be driven by a drive source and serves as the driven end.

[0033] See Figure 5In order to conveniently dismount the second end of the rocker 25 from the back of the smoke baffle 13, the second end of the rocker 25 is provided with a first connecting piece 31, and the back of the smoke baffle 13 is provided with a second connecting piece 32. One of the first connecting piece 31 and the second connecting piece 32 is provided with a slot 310, and the other is provided with an insertion block 321 which is adapted to the slot 310 and can be inserted into the slot 310. In the specific installation, the first connecting piece 31 can be installed to the second end of the rocker 25, the second connecting piece can be installed to the back of the smoke baffle 13, then the insertion block 321 is inserted into the corresponding slot 310, and the insertion block 321 is limited from being taken out of the slot 310 by the limiting structure. When the first connecting piece 31 is installed to the second end of the rocker 25, the installation operation can be conveniently performed due to the absence of the interference of the smoke baffle 13, the assembly efficiency of the smoke baffle 13 is improved, and the labor cost is reduced. In the preferred embodiment, the slot 310 is provided on the first connecting piece 31, and the insertion block 321 is provided on the second connecting piece 32. The extension direction of the insertion block 321 is parallel to the smoke baffle 13. Specifically, the extension direction of the slot 310 and the extension direction of the insertion block 321 are consistent with the width direction of the smoke baffle 13.

[0034] The first connecting piece 31 is in the U-shaped cross section, which includes the first baffle 311 and the second baffle 312 which are opposite and spaced apart, and the connecting plate 313 which is connected between the side of the first baffle 311 and the side of the second baffle 312. The connecting plate 313 is connected to the second end of the rocker 25 by the second screw 42. The gap between the first baffle 311 and the second baffle 312 constitutes the slot 310 of the first connecting piece 31, and the opening of the slot 310 is away from the rocker 25, i.e. the opening of the slot 310 is outward. Considering that the smoke baffle 13 is mainly made of glass plate, the second connecting piece 32 can be connected to the back of the smoke baffle 13 by the bonding. The second connecting piece 32 includes the fixed block 320 which is fixedly connected to the back of the smoke baffle 13, and the lug which protrudes outward from the side of the fixed block 320. The fixed block 320 is bonded to the back of the smoke baffle 13, and the lug has a gap with the back of the smoke baffle 13, and the lug constitutes the insertion block 321 of the second connecting piece 32. In the assembled state of the first connecting piece 31 and the second connecting piece 32, the lug is inserted into the slot 310, and at least the side edge of the first baffle 311 is inserted into the gap between the lug and the back of the smoke baffle 13.

[0035] The first connecting member 31 and / or the second connecting member 32 is further provided with a limiting structure for limiting the plug 321 from being pulled out of the slot 310. In some embodiments, the limiting structure can be a buckle structure arranged between the plug 321 and the slot 310 or a locking structure for locking the plug 321 and the slot 310 together (e.g. by a elastic protrusion and a clamping groove), or a limiting pin directly. In the preferred embodiment, in order to simplify the limiting structure and reduce the cost, the limiting structure includes a first screw 41 penetrating through the first baffle 311 and connected to the protrusion, the extending direction of the first screw 41 is substantially perpendicular to the smoke baffle 13, and the first baffle 311 and the protrusion of the first connecting member 31 are provided with screw holes corresponding to each other. When the first connecting member 31 and the second connecting member 32 are connected to the smoke baffle 13, the first baffle 311 of the first connecting member 31 is away from the second baffle 312, that is, the screw hole on the first baffle 311 is outwardly directed and can face the operator, so that the operator can conveniently screw without interference with the smoke baffle 13.

[0036] The inner wall of the slot 310 is further provided with a limiting groove 314 extending along the extending direction of the slot 310, and the protrusion is provided with a limiting protrusion 322 matched with the limiting groove 314, which can be a strip-shaped protrusion structure extending along the extending direction of the protrusion. When the first connecting member 31 and the second connecting member 32 are installed, the limiting protrusion 322 and the limiting groove 314 can be centered, and during the process of inserting the protrusion into the slot 310, the limiting protrusion 322 is correspondingly slid into the limiting groove 314, thereby avoiding displacement of the protrusion and the slot 310 in the width direction during installation.

[0037] Referring to Figure 6 In further preferred embodiments, the second connecting member 32 is provided with a limiting stop 323 adjacent to the end of the protrusion for limiting the protrusion from moving to a set position and continuing to move along the extending direction of the slot 310. The limiting stop 323 can be a protruding edge extending leftward or rightward from the end of the protrusion. During the process of slidingly installing the plug 321 into the slot 310, the limiting stop 323 of the plug 321 stops when it abuts against the port edge of the slot 310, that is, the limiting stop 323 of the plug 321 can define the limit position of the sliding installation of the plug 321, at which the screw hole on the first connecting member 31 and the screw hole on the second connecting member 32 can be centered, so that the operator can directly screw without holding the smoke baffle 13, thereby improving the assembly efficiency. The "set position" mentioned above can be understood as the relative position of the screw hole on the first connecting member 31 and the screw hole on the second connecting member 32.

[0038] The second ends of the two rocker levers 25 of this embodiment are each provided with the above-described first connecting member 31. The left and right ends of the back surface of the smoke baffle 13 are each provided with the above-described second connecting member 32.
