This embodiment provides an air deflector assembly, which is suitable for household appliances such as an integrated cooker with an air deflector and an air inlet structure, and is especially suitable for a range hood. As shown in Figures 1 to 5, the range hood includes a hood main body 100, the main wind plate 1 of the air deflector assembly is hinged on the main body 100 of the range hood through the connecting piece 13 of the air deflector, the main body 100 of the range hood and the main air flow The board 1 is movably connected, and the air deflector assembly can open or close the air inlet of the main body 100 of the hood. The specific structure is that the driving part 11 is connected between the main body 100 of the range hood and the main wind plate 1 , and the driving part 11 is used to drive the main wind plate 1 to open and close relative to the main body 100 of the range hood, thereby opening or closing the main body 100 of the range hood. Inlet.

When there is no oil fume, the main wind plate 1 closes the air inlet (not shown) of the hood main body 100. In this embodiment, the panel of the hood main body 100 is located on the same plane as the main wind plate 1; in other embodiments, The panel of the main body 100 of the hood and the main wind plate 1 can be at an obtuse angle; when sucking oil fume, the driver 11 will push the main air plate 1 away from the air inlet of the main body 100 of the hood by a certain distance, and will be blocked by the main wind. The air inlet behind the plate 1 is exposed, and a smoke collecting area is formed between the hood main body 100 and the main wind plate 1, and the oil fume is collected in the smoke cage area and enters the air inlet smoothly until it is discharged outside.

Wherein, the wind deflector assembly includes the main wind deflector 1, the first wind deflector 2, the second wind deflector 3 and the wind deflector drive assembly, the first wind deflector 2 is relatively movable connected to the main wind deflector 1, The second wind deflector 3 is connected to the first wind deflector 2 and can be deflected at a set angle relative to the first wind deflector 2; The limiting member 21 on the first wind deflector 2 and the force application seat 31 provided on the second wind deflector 3 .

The output end of the driving part 11 is connected to the main wind plate 1. After starting, the driving part 11 can push the main wind plate 1 to rotate around the wind guide plate connecting part 13 to set an angle, so as to realize the opening and closing of the main wind plate 1. The driving rod 121 on the driving device 12 pushes and pulls the first wind deflector 2 to a set position through the push-pull limiter 21 , so as to realize the switch of the first wind deflector 2 . When the end of the drive rod 121 passes over the stopper 21, the drive rod 121 can make the second wind deflector 3 tilt to a set angle relative to the first wind deflector 2 by pushing and pulling the force base 31 to realize the second wind deflector. Deflection and reset of plate 3. Preferably, the second air deflector 3 can deflect toward the main body 100 of the hood, thereby forming a buckle structure at the bottom of the first air deflector 2 , and the oil fume entering the smoke collection area is rebounded after hitting the second air deflector 3 In the direction of the air inlet, oil fume is prevented from escaping from the bottom edge of the first air deflector 2 . The driving device 12 may be, but not limited to, a push rod motor, an air cylinder or a hydraulic cylinder.

The main wind deflector 1, the first wind deflector 2 and the second wind deflector 3 of the wind deflector assembly can be opened separately, which increases the smoke collection area of the wind deflector, absorbs oil fume more thoroughly, and collects oil fume faster; After the second wind deflector 3 is inclined relative to the first wind deflector 2, a larger observation range is reserved for the user, avoiding the situation that the user cannot see the stove due to the shielding of the second wind deflector 3 , which is more convenient to use; the driving rod 121, the limiter 21 and the force applying seat 31 are located on the same straight line, the telescopic driving rod 121 can drive the translation of the first wind deflector 2 and the rotation of the second wind deflector 3 successively, and the structure is simple , takes up little space, is convenient to control, and the first wind deflector 2 and the second wind deflector 3 respond quickly.

The first wind deflector 2 and the second wind deflector 3 are connected together. When the first wind deflector 2 moves relative to the main wind deflector 1, the second wind deflector 3 will move synchronously with the first wind deflector 2 . The first wind deflector 2 and the second wind deflector 3 respectively have a closed position and an open position. When in the closed position, the first wind deflector 2 and the second wind deflector 3 are hidden on the back of the main wind deflector 1, and the shape is more Beautiful, with a more compact overall structure, meeting the design requirements of miniaturized air deflectors, simple and youthful design; when in the open position, the first air deflector 2 and the second air deflector 3 protrude from the main air deflector 1, which can increase the The smoke-collecting area of the large wind deflector is better for oil-absorbing smoke.

The wind deflector drive assembly also includes a sliding connection device, as shown in Figures 5 to 8, the sliding connection device includes a matching sliding post 41 and a sliding rail 42, one of the sliding post 41 and the sliding rail 42 is fixed on the On the main wind plate 1 , the other of the two is fixed on the first wind guide plate 2 , ensuring that the first wind guide plate 2 can move relative to the main wind plate 1 without being separated from the main wind plate 1 . Preferably, the sliding column 41 and the slide rail 42 are respectively arranged at positions close to the edges of the main wind deflector 1 and the first wind deflector 2, and the first wind deflector 2 can protrude from the main wind deflector 1 as much as possible, increasing the Large smoke collection area, more thorough range fume extraction.

The sliding column 41 is at least partly arranged in the sliding rail 42. When the driving rod 121 of the driving device 12 pushes and pulls the limiter 21, the sliding column 41 can move along the extending direction of the sliding rail 42, so that the first wind deflector 2 is relatively The translation of the main wind panel 1. Both ends of the slide rail 42 are closed, so as to prevent the sliding post 41 from slipping out at both ends of the slide rail 42 .

The sliding column 41 includes a connecting limiting sliding piece 411 and a connecting column 412 , the sliding rail 42 is a groove-shaped structure, and an elongated hole 421 is opened on one side of the groove-shaped structure. The width of the limit slide 411 is greater than the width of the connecting column 412, the limit slide 411 is located in the groove structure and is blocked by the edge of the groove structure, and the limit slide 411 cannot escape from the elongated hole 421; The column 412 partially protrudes from the elongated hole 421 , so as to be connected to the main wind deflector 1 or the first wind deflector 2 , so as to realize the connection between the main wind deflector 1 and the first wind deflector 2 . When pushed by an external force, the connecting column 412 can move along the extending direction of the elongated hole 421 to realize the translation of the first wind deflector 2 relative to the main wind deflector 1 .

In order to keep the first wind deflector 2 in the closed position under the push of the driving device 12, a locking structure is formed between the sliding column 41 and the slide rail 42, and the locking structure can at least carry the first wind deflector 2 and the second wind deflector. The sum of the gravitational forces of plate 3. Only when the driving device 12 starts to apply thrust to the first wind deflector 2, and the sum of the thrust value applied by the driving device 12 plus the gravity value of the first wind deflector 2 and the second wind deflector 3 is greater than what the locking structure can carry The locking structure will be unlocked only when the force value is higher, and the sliding column 41 will start to move along the extending direction of the sliding rail 42 .

The specific structure of the locking structure is not limited. Preferably, the limiting slide 411 is in an I-shape, and a limiting recess 413 is formed on both sides of the limiting sliding piece 411; A slider positioning assembly is provided, and the slider positioning assembly includes a positioning protrusion 422 arranged on the inner wall of the groove of the slide rail 42, a positioning adjustment member 423 arranged on the outside of the slide rail 42, and a positioning adjustment member 423 connected to the positioning protrusion 422 and the positioning adjustment The positioning elastic member 424 between the members 423. The positioning protrusion 422 is preferably hemispherical. When the driving force is large enough, the positioning protrusion 422 can slide out of the limiting recess 413 smoothly, so as to avoid complete jamming between the positioning protrusion 422 and the limiting recess 413 .

When the positioning protrusion 422 is stuck in the limiting recess 413, the limiting sliding piece 411 is fixed in the slide rail 42, and the first wind deflector 2 and the second wind deflector 3 are stationary relative to the main wind deflector 1 ; When a force greater than or equal to the set value is applied to the sliding column 41, the positioning protrusion 422 can be pushed away to both sides, and the positioning elastic member 424 is compressed until the positioning protrusion 422 withdraws from the limiting recess 413, limiting The position slide piece 411 can move in the sliding rail 42 along the extending direction of the sliding rail 42 to realize the movement of the first wind deflector 2 relative to the main wind deflector 1 . The sum of the gravity values of the first wind deflector 2 and the second wind deflector 3 is less than the thrust value pushing the positioning protrusion 422 to move sideways, preventing the first wind deflector 2 from sliding initially.

As shown in FIG. 9 , the driving rod 121 is preferably provided with a baffle 122 . As shown in FIG. 10 and FIG. 11 , the limiting member 21 includes two limiting columns 211 arranged in parallel. When the baffle plate 122 passes between the two limiting posts 211 , the driving rod 121 can push the first air deflector 2 to a position. After the baffle plate 122 passes between the two limiting posts 211 , the driving rod 121 no longer exerts force on the first wind deflector 2 . When the driving rod 121 pushes the second wind deflector 3 to rotate, the first wind deflector 2 will not move with the driving rod 121 .

A limit projection 212, a limit adjustment piece 213, and a limit elastic piece 214 arranged between the limit projection 212 and the limit adjuster 213 are respectively arranged on each limit post 211, and the limit elastic piece 214 can It is a variety of devices with elastic deformation capabilities such as springs, shrapnel, and torsion springs. The limit adjusting member 213 is fixed on the limit post 211, so one end of the limit elastic member 214 is fixed, and the other end is a free end. When the limiting protrusion 212 is squeezed by an external force, the free end of the limiting elastic member 214 will move along the extension direction of the external force, thereby compressing the length of the limiting elastic member 214 . The limiting elastic member 214 accumulates elastic potential energy, and when the external force is removed, the limiting elastic member 214 can reversely push the limiting protrusion 212 to realize the reset of the limiting protrusion 212 .

The two position-limiting protrusions 212 on the two position-limiting posts 211 are oppositely arranged, and the driving rod 121 can pass between the two position-limiting posts 211 when stretching. When the driving rod 121 passes between the two limiting posts 211 , the baffle plate 122 will collide with the limiting protrusion 212 . When the striking force of the baffle 122 is strong enough, the limiting protrusion 212 will move toward the direction of compressing the limiting elastic member 214 until the baffle 122 passes between the two limiting posts 211 .

The force of the lateral movement of the limiting protrusion 212 is set to be greater than the force of the lateral movement of the positioning protrusion 422, so when the driving rod 121 hits the limiting member 21 during the elongation process, the positioning protrusion 422 will be displaced laterally , until the positioning protrusion 422 withdraws from the limiting recess 413, the limiting slide 411 moves in the sliding rail 42 along the extending direction of the sliding rail 42, so that the first air deflector 2 moves to the bottom relative to the main air deflector 1 end; after the first wind deflector 2 can no longer move relative to the main wind deflector 1, all the force on the driving rod 121 is applied to the limit piece 21 until the limit protrusion 212 moves sideways, and the baffle 122 moves from the two limit The position posts 211 pass through, and the driving rod 121 hits the force applying seat 31 accurately.

When the driving rod 121 collides with the limiter 21 during shrinkage, it will first push the limit slide 411 to slide in the slide rail 42 until the positioning projection 422 snaps into the limit recess 413 again, and then the baffle plate 122 is applied The force on the limiting member 21 increases enough to push the limiting protrusion 212 to move sideways, and the baffle plate 122 passes between the two limiting posts 211 and retracts to its original position.

The setting of the limiting member 21 enables the driving rod 121 to drive the first wind deflector 2 to move when necessary. But the driving rod 121 is not connected with the first wind deflector 2. When the driving rod 121 needs to drive the second wind deflector 3 to rotate, the driving rod 121 is separated from the first wind deflector 2. At this time, the first wind deflector Plate 2 will not move with drive rod 121 . That is, only one driving rod 121 can drive the first wind deflector 2 and the second wind deflector 3 respectively, which is more convenient to use and has a simpler driving structure; the driving rod 121 only needs to move linearly to drive the first wind deflector. When the plate 2 moves and the second wind deflector 3 rotates, the corresponding speed of the first wind deflector 2 and the second wind deflector 3 is faster.

As shown in Fig. 5 and Fig. 12, a hinge 5 is preferably connected between the first wind deflector 2 and the second wind deflector 3, and the hinge 5 includes a child hinge 52 and a mother hinge connected by a hinge post 51 53 , one of the child hinge 52 and the female hinge 53 is fixed on the first wind deflector 2 , and the other of the two is fixed on the second wind deflector 3 . The sub-hinge 52 and the female hinge 53 can rotate around the hinge column 51, and realize the first wind deflector 2 and the second wind deflector 2 without affecting the rotation of the second wind deflector 3 relative to the first wind deflector 2 . 3 connections, the overall structure is more stable.

In order to keep the first wind deflector 2 and the second wind deflector 3 in the same plane when the driving rod 121 is not pushed, the sub-hinge 52 and the mother hinge 53 are respectively provided with magnetic elements 54, and the sub-hinge 52 After the magnetic part 54 and the magnetic part 54 of the female hinge 53 are attracted, the first wind deflector 2 and the second wind deflector 3 are on the same plane, and the child hinge 52 or the female hinge connected to the second wind deflector 3 The hinge 53 will not sag due to the gravity of the second wind deflector 3 .

As shown in FIG. 4 , FIG. 5 , FIG. 13 and FIG. 14 , the force applying seat 31 includes a seat main body 311 on which a connecting piece 312 , a through hole 314 and a relay piece 315 are arranged. The seat main body 311 is connected to the second wind deflector 3 through the connecting piece 312 to ensure that when the driving rod 121 hits the relay 315 , the second wind deflector 3 can move synchronously with the seat main body 311 . A hinge 313 is fixedly arranged on the first wind deflector 2, and the seat main body 311 is sleeved on the hinge 313 through a through hole 314. When the driving rod 121 hits the seat main body 311, the seat main body 311 can rotate around the hinge 313, Until the second wind deflector 3 is tilted to a set angle relative to the first wind deflector 2 . The relay 315 is arranged on the side of the seat body 311 close to the drive rod 121. When the drive rod 121 hits the seat body 311, the drive rod 121 will abut against the relay 315 to ensure that the impact force on the seat body 311 is more stable.

After the baffle plate 122 passes between the two limiting columns 211, the end 123 of the driving rod 121 will hit the relay 315, so that the seat main body 311 and the second wind deflector 3 rotate around the hinge 313 as a whole, and the The magnetic part 54 of the hinge 52 is separated from the magnetic part 54 of the female hinge 53; when the driving rod 121 is retracted, under the pulling force of the driving rod 121 or under the self-weight of the second wind deflector 3, the second guide The air plate 3 is reset, and the magnetic component 54 of the child hinge 52 and the magnetic component 54 of the female hinge 53 are attracted again.

The relay 315 is preferably spherical, and the end 123 of the driving rod 121 is preferably a hemispherical concave surface. The spherical relay 315 can be embedded in the end 123 and roll in the end 123, so as to prevent the relay 315 from moving with the seat main body 311. The relay member 315 is separated from the end 123 of the driving rod 121 to ensure the stability of the movement of the second wind deflector 3 .

The relay 315 is magnetically connected to the end 123 of the driving rod 121 , and when the driving rod 121 is retracted, the relay 315 can be pulled to move synchronously, and the seat body 311 is reset. There is no need to provide an independent reset driving device for the seat main body 311, the overall structure is simpler, the cost is low, and the seat main body 311 resets faster.
