Description

Technical Field

[0001] This invention relates to the field of range hood technology, and in particular to a cleaning component linkage device and a range hood. Background Technology

[0002] Range hoods are common household appliances in kitchens. They operate on the principles of fluid dynamics, using a centrifugal fan installed inside to draw in and exhaust cooking fumes. The centrifugal fan consists of a volute, an impeller housed within the volute, and a motor that drives the impeller. When the impeller rotates, a negative pressure is generated at the fan's center, drawing in the cooking fumes from below the range hood. These fumes are then drawn through the duct inlet to the fan, where they are accelerated and collected by the volute before being expelled outdoors. During use, it's essential to clean the impeller regularly to prevent large grease particles from disrupting the impeller's dynamic balance, causing increased vibration and noise. In some technologies, the impeller's cleaning components are typically immovable and exposed within the range hood's interior, regardless of usage. This leads to frequent grease buildup on the surface of these components, which can eventually clog the nozzles over time. Summary of the Invention

[0042] To make the movement of the cleaning components more flexible, prevent oil fumes from contaminating the cleaning components, and improve the oil-proof effect of the cleaning components, this disclosure provides a cleaning component linkage device and a range hood.

[0043] Figure 1 This is a schematic diagram illustrating the structure of a cleaning component linkage device and a range hood according to an exemplary embodiment, as shown below. Figure 1 As shown, the cleaning component linkage device includes: a first linkage mechanism 1 and a second linkage mechanism 2; one side of the first linkage mechanism 1 is connected to the lifting mechanism 3, and the other side is connected to the cleaning component 4. The first linkage mechanism 1 is used to link the lifting mechanism 3 and the cleaning component 4, and the cleaning component 4 is used to clean the fan impeller 5.

[0044] In this embodiment, the first linkage mechanism 1 is a movable structure, with its movable ends connected to the bottom of the cleaning component 4 and the top of the lifting mechanism 3, respectively. The cleaning component 4 has several spray holes on its surface for cleaning the fan impeller 5. The lifting mechanism 3 is located inside the range hood, movably connected to the range hood housing, and is positioned opposite to the flue inlet 7. Through the connection between the first linkage mechanism 1, the cleaning component 4, and the lifting mechanism 3, the cleaning component 4 can move simultaneously during the upward and downward movement of the lifting mechanism 3.

[0045] The second linkage mechanism 2 is connected to the smoke baffle 6 on one side and to the lifting mechanism 3 on the other side. The second linkage mechanism 2 is used to link the smoke baffle 6 and the lifting mechanism 3. The lifting mechanism 3 is correspondingly set with the flue air inlet 7.

[0046] In this embodiment, the second linkage mechanism 2 is a movable structure, with its movable ends connected to the inner side of the smoke baffle 6 and the bottom of the lifting mechanism 3, respectively. The smoke baffle 6 is the smoke baffle on the outer side of the range hood, movably connected to the range hood housing. The lifting mechanism 3 is located in the inner cavity of the range hood, movably connected to the range hood housing, and is positioned opposite to the flue inlet 7. Through the connection between the second linkage mechanism 2, the smoke baffle 6, and the lifting mechanism 3, the lifting mechanism 3 can move simultaneously when the smoke baffle 6 moves outward to open, and simultaneously when the smoke baffle 6 moves inward to close.

[0047] In an optional embodiment, such as Figure 2 As shown, the first linkage mechanism 1 includes: a first push rod 11 and a second push rod 12; one end of the first push rod 11 and one end of the second push rod 12 are movably connected; the other end of the first push rod 11 is movably connected to the bottom of the cleaning component 4, and the other end of the second push rod 12 is connected to the lifting mechanism 3.

[0048] In this embodiment, one end of the first push rod 11 and one end of the second push rod 12 can be connected by a rotating shaft, the other end of the first push rod 11 can be connected to the bottom of the cleaning component 4 by a rotating shaft, and the other end of the second push rod 12 can be fixedly connected to the lifting mechanism 3 by welding.

[0049] As can be seen from the above, in this embodiment of the present disclosure, one end of the first push rod 11 and one end of the second push rod 12 are movably connected; the other end of the first push rod 11 is movably connected to the bottom of the cleaning component 4, and the other end of the second push rod 12 is connected to the lifting mechanism 3, so that the cleaning component 4 and the lifting mechanism 3 can be linked through one end of the first push rod 11 and the second push rod 12.

[0050] In an optional embodiment, such as Figure 2 As shown, the cleaning component 4 is fitted into the cleaning component base 8, and the cleaning component base 8 is fixed to the inner cavity of the range hood; the first push rod 11 is used to drive the cleaning component 4 to move in the opening direction of the cleaning component base 8.

[0051] In this embodiment, the cleaning component base 8 is fixedly disposed within the inner cavity of the fan impeller. The cleaning component base 8 is a sleeve-shaped structure, perpendicular to the rear panel of the range hood, with its central axis aligned with the central axis of the fan impeller. The open end of the cleaning component base 8 faces the fan impeller. The cleaning component 4 is sleeved within the cleaning component base 8. The bottom of the cleaning component base 8 has a long strip-shaped connecting port, through which one end of the first push rod 11 is movably connected to the cleaning component 4.

[0052] In this embodiment, during the descent of the lifting mechanism 3, the lifting mechanism 3 drives the second push rod 12 to descend. The second push rod 12 drives the end of the first push rod 11 connected to the second push rod 12 to descend. The end of the first push rod 11 connected to the cleaning component 4 moves towards the rear panel of the range hood, thereby driving the cleaning component 4 to move into the cleaning component base 8. During the ascent of the lifting mechanism 3, the lifting mechanism 3 drives the second push rod 12 to rise. The second push rod 12 drives the end of the first push rod 11 connected to the second push rod 12 to rise. The end of the first push rod 11 connected to the cleaning component 4 moves away from the rear panel of the range hood, thereby driving the cleaning component 4 to move outward from the cleaning component base 8.

[0053] As can be seen from the above, in this embodiment of the present disclosure, the cleaning component 4 is sleeved in the cleaning component base 8, which enables the cleaning component 4 to move along the opening direction of the cleaning component base 8 under the drive of the first push rod 11, and to achieve linkage with the lifting mechanism 3 through the connection between the first push rod 11, the second push rod 12 and the lifting mechanism 3.

[0054] In an optional embodiment, such as Figure 3 As shown, a sealing cover 81 is provided at the opening of the cleaning component base 8.

[0055] In this embodiment, the sealing cover 81 may be made of rubber to prevent the cleaning component 4 from being contaminated by oil fumes when it is inside the cleaning component base 8.

[0056] In an optional embodiment, such as Figure 2 As shown, the second linkage mechanism 2 includes: a first connecting rod 21, a first slide rail 22, a second connecting rod 23, and a second slide rail 24; the first connecting rod 21 slides along the first slide rail 22, and the second connecting rod 23 slides along the second slide rail 24. Both the first slide rail 22 and the second slide rail 24 are located in the inner cavity of the range hood; one side of the first connecting rod 21 is connected to the smoke baffle 6, and the other side of the first connecting rod 21 is connected to the second connecting rod 23. One end of the second connecting rod 23 is connected to the lifting mechanism 3, and the other end of the second connecting rod 23 is movably connected to the second slide rail 24.

[0057] In this embodiment, the first slide rail 22 can be fixedly installed on the side wall of the inner cavity of the range hood, and the extension direction of the first slide rail 22 forms an acute angle with the top plate of the inner cavity of the range hood. The second slide rail 24 is fixedly installed on the side wall where the first slide rail 22 is located, and the second slide rail 24 is vertically installed.

[0058] In this embodiment, one side of the first connecting rod 21 is movably connected to the inner side of the smoke baffle 6, the other side of the first connecting rod 21 is movably connected to the middle of the second connecting rod 23, one end of the second connecting rod 23 is movably connected to the bottom of the lifting mechanism 3, and the other end of the second connecting rod 23 is movably connected to the second slide rail 24.

[0059] Based on the above, in this embodiment of the present disclosure, the first connecting rod 21 slides along the first slide rail 22, and the second connecting rod 23 slides along the second slide rail 24, so that the first connecting rod 21 and the second connecting rod 23 can move along predetermined trajectories respectively; one side of the first connecting rod 21 is connected to the smoke baffle 6, and the other side is connected to the second connecting rod 23, one end of the second connecting rod 23 is connected to the lifting mechanism 3, and the other end is movably connected to the second slide rail 24, so that the smoke baffle 6 and the lifting mechanism 3 can be linked by the first connecting rod 21 and the second connecting rod 23.

[0060] In an optional embodiment, such as Figure 3 As shown, the first connecting rod 21 includes a first rocker arm 211 and a second rocker arm 212; the second connecting rod 23 includes a third rocker arm 231 and a fourth rocker arm 232; one end of the first rocker arm 211 is fixedly connected to one end of the second rocker arm 212, and the movable end of the first rocker arm 211 is connected to the smoke baffle 6; one end of the third rocker arm 231 is movably connected to one end of the fourth rocker arm 232, and the connection between the third rocker arm 231 and the fourth rocker arm 232 is connected to the movable end of the second rocker arm 212; the other end of the third rocker arm 231 is fixed to the inner cavity of the range hood, and the other end of the fourth rocker arm 232 is connected to the lifting mechanism 3.

[0061] In this embodiment, the fixing method of one end of the first rocker 211 and one end of the second rocker 212 can be welding, or a first connecting rod 21 including the first rocker 211 and the second rocker 212 can be integrally formed. The movable end of the first rocker 211 is movably connected to the inner side of the smoke baffle 6. During the movement of the smoke baffle 6, the angle between the movable end of the first rocker 211 and the smoke baffle 6 changes continuously. The movable end of the second rocker 212 is movably connected to the middle of the second connecting rod 23. During the movement of the smoke baffle 6, the angle between the movable end of the second rocker 212 and the second connecting rod 23 changes continuously.

[0062] In this embodiment of the disclosure, the movable connection between one end of the third rocker 231 and one end of the fourth rocker 232 can be via a pivot. The pivot is the connection point between the third rocker 231 and the fourth rocker 232, and the movable end of the second rocker 212 is movably connected to the connection point between the third rocker 231 and the fourth rocker 232 via the pivot.

[0063] In this embodiment, the other end of the third rocker arm 231 is fixed to the side wall of the inner cavity of the range hood, and the other end of the fourth rocker arm 232 is movably connected to the bottom of the lifting mechanism 3. During the movement of the lifting mechanism 3, the angle between the other end of the fourth rocker arm 232 and the lifting mechanism 3 changes continuously.

[0064] In this embodiment, since the first rocker arm 211 and the second rocker arm 212 are fixedly connected, the angle between the first rocker arm 211 and the second rocker arm 212 remains unchanged during the linkage between the smoke baffle 6 and the lifting mechanism 3. Since the second rocker arm 212, the third rocker arm 231 and the fourth rocker arm 232 are movably connected, the angle between the third rocker arm 231 and the fourth rocker arm 232 changes during the linkage between the smoke baffle 6 and the lifting mechanism 3. Since the fourth rocker arm 232 is movably connected to the lifting mechanism 3, the angle between the fourth rocker arm 232 and the lifting mechanism 3 changes during the linkage between the smoke baffle 6 and the lifting mechanism 3.

[0065] Based on the above, in this embodiment, one end of the first rocker 211 is fixedly connected to one end of the second rocker 212, the movable end of the first rocker 211 is connected to the smoke baffle 6, one end of the third rocker 231 is movably connected to one end of the fourth rocker 232, and the connection between the third rocker 231 and the fourth rocker 232 is connected to the movable end of the second rocker 212; the other end of the third rocker 231 is fixed to the inner cavity of the range hood, and the other end of the fourth rocker 232 is connected to the lifting mechanism 3. The movement of the smoke baffle 6 and the lifting mechanism 3 can be flexibly linked through the connection relationship between the first rocker 211, the second rocker 212, the third rocker 231, the fourth rocker 232 and the lifting mechanism 3.

[0066] In an optional embodiment, such as Figure 3 As shown, the first connecting rod 21 also includes a first slider 213; the first slider 213 is disposed at the bent part of the first rocker arm 211, the bent part is the connection point between the first rocker arm 211 and the second rocker arm 212, and the first slider 213 is used to drive the first rocker arm 211 to slide along the first slide rail 22.

[0067] In this embodiment, the first slider 213 is disposed on the back side of the bent portion of the first rocker arm 211, that is, on the back side of the connection between the first rocker arm 211 and the second rocker arm 212, so as to drive the first rocker arm 211 to slide back and forth along the first slide rail 22. During the opening process of the smoke baffle 6, the first slider 213 drives the first rocker arm 211 to slide forward along the first slide rail 22. During the closing process of the smoke baffle 6, the first slider 213 drives the first rocker arm 211 to slide backward along the first slide rail 22.

[0068] As can be seen from the above, in this embodiment of the present disclosure, by setting a first slider 213 at the connection between the first rocker arm 211 and the second rocker arm 212, the movement of the first connecting rod 21 can be flexibly realized, making the linkage between the smoke baffle 6 and the lifting mechanism more flexible.

[0069] In an optional embodiment, such as Figure 3As shown, the second link 23 also includes a second slider 233; the second slider 233 is disposed at the end of the fourth rocker 232 connected to the lifting mechanism 3, and the second slider 233 is used to drive the first rocker 211 and the end of the fourth rocker 232 connected to the lifting mechanism 3 to slide along the second slide rail 24.

[0070] In this embodiment, the second slider 233 is disposed at the end where the fourth rocker 232 is connected to the lifting mechanism 3, so as to drive the connection end of the fourth rocker 232 and the lifting mechanism 3 and the lifting mechanism 3 to slide back and forth along the second slide rail 24. During the opening process of the smoke baffle 6, the second slider 233 drives the lifting mechanism 3 to slide downward along the second slide rail 24. During the closing process of the smoke baffle 6, the second slider 233 drives the lifting mechanism 3 to slide upward along the lifting mechanism 3.

[0071] As can be seen from the above, by setting a second slider 233 at the end of the fourth rocker 232 connected to the lifting mechanism 3, the movement of the end of the fourth rocker 232 connected to the lifting mechanism 3 and the lifting mechanism 3 can be flexibly realized, making the linkage between the smoke baffle 6 and the lifting mechanism 3 more flexible.

In this embodiment, one end of the drive rod is fixed to the side wall of the range hood cavity, and the other end of the drive rod is movably connected to the inner side of the smoke baffle 6. During the movement of the smoke baffle 6, the angle between the drive rod and the smoke baffle 6 changes continuously.
