The embodiment provides an air deflector device, which is suitable for household appliances such as integrated cookers with air deflectors and air inlet structures, and is particularly suitable for range hoods. As shown in fig. 1 to 7, the range hood includes a hood body 100, a panel 300 and a main air deflector 1 are disposed on the hood body 100, the hood body 100 is movably connected to the main air deflector 1, and the main air deflector 1 can open or close an air inlet of the hood body 100. The specific structure is that a driving part 200 is connected between the main air deflector 1 and the cigarette machine main body 100, and the driving part 200 can drive the main air deflector 1 to open and close relative to the cigarette machine main body 100, so as to open or close an air inlet of the cigarette machine main body 100. In a non-working state, as shown in fig. 2, the main air deflector 1 closes an air inlet (not shown) of the main body 100 of the range hood, and the panel 300 and the main air deflector 1 may be in the same inclined plane or form an obtuse angle therebetween; in an operating state, as shown in fig. 3, the driving member 200 pushes the main air deflector 1 in a direction away from the air inlet of the main body 100 of the range hood, so that the air inlet behind the main air deflector 1 is exposed until the main air deflector 1 inclines at a set angle relative to the main body 100 of the range hood. A smoke gathering area is formed between the main air deflector 1 and the cigarette machine main body 100, and the oil smoke gathered in the smoke gathering area enters the cigarette machine main body 100 from an air inlet and then is discharged outdoors.

The air deflector device comprises a main air deflector 1, a first air deflector 2, a second air deflector 4 and a second driving assembly. The first air deflector 2 is connected to the main air deflector 1 in a sliding mode, and the second air deflector 4 is hinged to the first air deflector 2; the second driving assembly is used for driving the second air deflector 4 to rotate relative to the first air deflector 2.

When the range hood is in a non-working state, the first air deflector 2 and the second air deflector 4 can be hidden behind the main air deflector 1, so that the range hood is beneficial to reducing the volume, occupies small space and is more attractive in appearance; when the range hood works, the first air deflector 2 and the second air deflector 4 at least partially extend out of the main air deflector 1, the area of a smoke gathering area can be increased, and the smoke absorption effect is better.

The independent second driving assembly is arranged on the second air deflector 4, the structure and the control method of the driving device are simpler, the switch of the second air deflector 4 can be independently controlled no matter what state the first air deflector 2 is (extending out of the main air deflector 1 or being hidden behind the main air deflector 1), the use is more convenient, and the response speed of the second air deflector 4 is higher. The second air deflector 4 inclined towards the direction of the cigarette machine main body 100 can form a blocking structure at the bottom edge of the first air deflector 2, so that the oil smoke in the smoke gathering area is prevented from escaping from the bottom edge of the first air deflector 2, and the oil smoke is absorbed more thoroughly; after the second air deflector 4 rotates for a certain angle, a larger sight range can be reserved for a user, and the safety of the cooking process is ensured.

On the basis of the structure, the air deflector device further comprises a sliding connection assembly. The sliding connection assembly comprises a sliding column 31 and a sliding way 32 which are matched with each other, one of the sliding column 31 and the sliding way 32 is arranged on the main air deflector 1, and the other is arranged on the first air deflector 2; the second driving assembly is used for driving the second air deflector 4 to rotate around the hinge part relative to the first air deflector 2.

The specific opening manner of the first air guiding plate 2 is not limited, and the first air guiding plate 2 can be opened manually, as shown in fig. 6, a user holds the first air guiding plate 2 with both hands and pushes and pulls the first air guiding plate with force, so that the sliding column 31 can move in the sliding way 32, and the first air guiding plate 2 slides relative to the main air guiding plate 1, thereby opening and closing the first air guiding plate 2.

As shown in fig. 7, 12 and 13, the first driving assembly may further include a telescopic rod 51 and a driver 52 for driving the telescopic rod 51 to extend and retract, and when the telescopic rod 51 extends and retracts, the first air deflector 2 may be driven to move along the extending direction of the main air deflector 1. The driver 52 may be, but is not limited to, a push rod motor, an air cylinder or a hydraulic cylinder, and it is sufficient that the telescopic rod 51 is driven to move along the axis. The driver 52 is used for driving the first air deflector 2 to move, so that the use is more convenient and labor-saving, and the air deflector is particularly suitable for the old, the young and the weak.

The driver 52 is preferably arranged on the main air deflector 1, so that the mounting structure is more stable; the end of the telescopic rod 51 can be hinged to the first air guide plate 2, the connecting structure between the telescopic rod 51 and the first air guide plate 2 is more stable, and the situation that the first air guide plate 2 is not moved in place due to the fact that the telescopic rod 51 is separated from the first air guide plate 2 is avoided. Of course, other connection methods, such as magnetic connection, may be adopted between the telescopic rod 51 and the first air guiding plate 2, and the telescopic rod 51 may drive the first air guiding plate 2 to move.

As shown in fig. 8 and 10, the slide column 31 includes a stopper slide piece 311 and a connection column 312 connected together, the stopper slide piece 311 is wider than the connection column 312, and a stopper recess 313 is formed at a side surface of the stopper slide piece 311.

As shown in fig. 9 and 10, the slide 32 includes a slide main body 321, an elongated hole 322 is formed on a top surface of the slide main body 321, a slide accommodating chamber (not shown) is formed inside the slide main body 321, and a width of the elongated hole 322 is smaller than a width of the slide accommodating chamber. The limiting sliding piece 311 is arranged in the sliding piece accommodating cavity, and the connecting column 312 is located in the long hole 322 and can move along the extending direction of the long hole 322. The width of the limiting sliding piece 311 is larger than that of the long hole 322, so that the limiting sliding piece 311 is ensured not to be separated from the long hole 322. A positioning elastic block 323 is arranged in the slide sheet accommodating cavity, the positioning elastic block 323 is preferably hemispherical, and when the positioning elastic block 323 is positioned in the limiting concave part 313, the slide column 31 is fixed relative to the slide way 32; the slide column 31 can slide in the slide way 32 only when the positioning spring block 323 is disengaged from the stopper recess 313.

The specific manner of the positioning elastic block 323 for clamping the limiting concave part 313 is not limited, and preferably, the slideway 32 further comprises a positioning adjusting part 324 and a positioning elastic part 325, the positioning elastic part 325 is connected between the positioning elastic block 323 and the positioning adjusting part 324, and the positioning adjusting part 324 can adjust the thrust value of the positioning elastic part 325 acting on the positioning elastic block 323. The positioning elastic member 325 may be, but is not limited to, a spring or a leaf spring.

When no external force is used for driving, the positioning elastic piece 325 extrudes the positioning elastic block 323 towards the direction of the middle part of the slide sheet accommodating cavity, and the positioning elastic block 323 is clamped in the limiting concave part 313, so that the sliding column 31 is prevented from moving along the sliding way 32; when an external force pushes the slide column 31 to move and the component force of the pushing force acting on the positioning elastic block 323 is greater than the elastic force of the positioning elastic piece 325, the positioning elastic piece 323 extrudes the positioning elastic piece 325 in the direction away from the middle of the slide sheet accommodating cavity until the positioning elastic block 323 completely disengages from the limiting concave part 313. After the slide column 31 moves to a set position in the slide way 32, the positioning elastic block 323 and the limiting slide sheet 311 are completely staggered, the positioning elastic piece 325 extrudes the positioning elastic block 323 towards the middle of the slide sheet accommodating cavity again, and the positioning elastic block 323 protrudes out of the inner wall surface of the slide sheet accommodating cavity to prepare for fixing the limiting slide sheet 311 next time.

Besides the hinge connection, as shown in fig. 7 and 11, the first driving assembly preferably further includes a limiting member 21 disposed on the first air guiding plate 2, the limiting member 21 includes limiting posts 211 disposed in parallel, each limiting post 211 is respectively provided with a limiting protrusion 212, a limiting adjusting member 213, and a limiting elastic member 214 disposed between the limiting protrusion 212 and the limiting adjusting member 213. The two limiting protrusions 212 on the two limiting columns 211 are oppositely arranged, and the telescopic rod 51 can push the two limiting protrusions 212 to move outwards when passing through between the two limiting columns 211. The elastic limiting element 214 may be, but is not limited to, a spring or a leaf spring.

The force required by compressing the extrusion limiting elastic part 214 is greater than the force required by compressing the extrusion positioning elastic part 325, so that when the telescopic rod 51 is abutted to the limiting part 21, the first air deflector 2 is firstly pushed to move relative to the main air deflector 1; until the first air guiding plate 2 moves to the lowest position, the telescopic rod 51 abuts against the limiting member 21 and then completely acts on the limiting protrusion 212. When the pushing force on the telescopic rod 51 is large enough, the force of the telescopic rod 51 acting on the limiting protrusion 212 is larger than the pushing force of the limiting elastic member 214, the limiting protrusion 212 moves towards the direction of compressing the limiting elastic member 214, and the telescopic rod 51 passes through the two limiting columns 211.

In order to enable the telescopic rod 51 to push the limiting protrusion 212 when extending and contracting, as shown in fig. 12 and 13, a linear or i-shaped baffle 511 is disposed on the telescopic rod 51, and when the telescopic rod 51 passes through between the two limiting posts 211, the baffle 511 can push the limiting protrusion 212 to move towards the direction of compressing the limiting elastic member 214. Of course, the shape of the baffle 511 may be other shapes, and it is sufficient that the stopper protrusion 212 is driven to press the stopper elastic member 214.

The specific push-pull manner between push-pull rod 62 and rotating arm 63 is not limited, and preferably, spherical abutting piece 632 is further disposed on rotating arm 63, a hemispherical abutting concave surface 621 is disposed at an end of push-pull rod 62, and abutting concave surface 621 can at least partially wrap abutting piece 632. When the rotating arm 63 rotates around the rotating positioning column, a certain degree of dislocation exists between the abutting part 632 and the abutting concave surface 621, and the abutting part 632 can be prevented from being separated from the abutting concave surface 621 due to the wrapping relation between the abutting concave surface 621 and the abutting part 632, so that the moving stability of the rotating arm 63 is ensured.
