Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air deflector assembly and a range hood comprising the air deflector assembly. Background Art

[0002] A range hood is a household appliance that collects and removes cooking fumes and residual gas from gas combustion. It primarily comes in two styles: side-suction and ceiling-suction. Side-suction range hoods have an air intake located on the side of the stove, creating an aesthetically pleasing design. Compared to ceiling-suction range hoods, side-suction range hoods block less light from the room.

[0003] To better collect oil smoke and exhaust gases, some side-suction range hoods are equipped with large air deflectors. However, these are bulky, obstruct vision, and are difficult to clean. To meet market needs, the air deflectors on side-suction range hoods should not be too large.

[0004] Existing small-panel side-suction range hoods typically feature an openable air deflector. Opening the deflector expands the smoke collection area, more thoroughly removing oil smoke and exhaust gases. Key drawbacks include: the drive mechanism for opening and closing the air deflector is complex and space-consuming, hindering overall range hood miniaturization; the smoke collection area remains relatively small, making it difficult to completely contain sudden, large volumes of oil smoke, resulting in poor exhaust efficiency. Summary of the Invention

[0048] This embodiment provides an air guide plate assembly suitable for household appliances with air guide plates and air inlet structures, such as integrated stoves, and is particularly suitable for range hoods. Figures 1 to 5 As shown, the range hood includes a range hood body 100. The main air guide plate 1 of the air guide plate assembly is hingedly connected to the range hood body 100 via an air guide plate connector 13. The range hood body 100 and the main air guide plate 1 are movably connected, and the air guide plate assembly can open or close the air inlet of the range hood body 100. Specifically, a driving member 11 is connected between the range hood body 100 and the main air guide plate 1. The driving member 11 is used to drive the main air guide plate 1 to open and close relative to the range hood body 100, thereby opening or closing the air inlet of the range hood body 100.

[0049] When not absorbing oil smoke, the main air guide plate 1 closes the air inlet (not shown) of the range hood main body 100. In this embodiment, the panel of the range hood main body 100 and the main air guide plate 1 are located in the same plane; in other embodiments, the panel of the range hood main body 100 and the main air guide plate 1 can be at an obtuse angle; when absorbing oil smoke, the driving member 11 pushes the main air guide plate 1 a certain distance away from the air inlet of the range hood main body 100, exposing the air inlet blocked behind the main air guide plate 1, and a smoke collection area is formed between the range hood main body 100 and the main air guide plate 1. The oil smoke gathers in this smoke collection area and smoothly enters the air inlet until it is discharged outdoors.

[0050] Among them, the wind guide plate assembly includes a main wind guide plate 1, a first wind guide plate 2, a second wind guide plate 3 and an wind guide plate driving assembly. The first wind guide plate 2 can be relatively movably connected to the main wind guide plate 1, and the second wind guide plate 3 is connected to the first wind guide plate 2 and can be deflected at a set angle relative to the first wind guide plate 2; the wind guide plate driving assembly includes a driving device 12 arranged on the main wind guide plate 1, a limiting member 21 arranged on the first wind guide plate 2, and a force seat 31 arranged on the second wind guide plate 3.

[0051] The output end of the driver 11 is connected to the main air guide plate 1. Once activated, the driver 11 can push the main air guide plate 1 to rotate around the air guide plate connector 13 to a set angle, thereby opening and closing the main air guide plate 1. The drive rod 121 on the driver 12 pushes and pulls the first air guide plate 2 to a set position by pushing and pulling the limiter 21, thereby opening and closing the first air guide plate 2. When the end of the drive rod 121 passes the limiter 21, the drive rod 121 can push and pull the force seat 31 to tilt the second air guide plate 3 relative to the first air guide plate 2 to a set angle, thereby deflecting and resetting the second air guide plate 3. Preferably, the second air guide plate 3 can deflect toward the range hood body 100, thereby forming a rebate structure at the bottom of the first air guide plate 2. After oil smoke entering the smoke collection area hits the second air guide plate 3, it is rebounded toward the air inlet, preventing the oil smoke from escaping from the bottom edge of the first air guide plate 2. The driver 12 can be, but is not limited to, a push rod motor, a cylinder, or a hydraulic cylinder.

[0052] The main air guide plate 1, the first air guide plate 2 and the second air guide plate 3 of the air guide plate assembly can be opened separately, which increases the smoke collection area of ​​the air guide plate, absorbs the oil smoke more thoroughly, and collects the oil smoke faster; after the second air guide plate 3 is tilted relative to the first air guide plate 2, a larger observation range is left for the user, avoiding the user from not being able to see the situation on the stove due to the obstruction of the second air guide plate 3, and is more convenient to use; the driving rod 121, the limit member 21 and the force seat 31 are located on the same straight line, and the driving rod 121 can be extended and retracted to drive the first air guide plate 2 to move horizontally and the second air guide plate 3 to rotate in turn. It has a simple structure, occupies a small space, is easy to control, and the first air guide plate 2 and the second air guide plate 3 have a fast response speed.

[0053] The first air deflector 2 and the second air deflector 3 are connected together. When the first air deflector 2 moves relative to the main air deflector 1, the second air deflector 3 moves synchronously with the first air deflector 2. The first air deflector 2 and the second air deflector 3 respectively have a closed position and an open position. When in the closed position, the first air deflector 2 and the second air deflector 3 are hidden behind the main air deflector 1, which has a more beautiful appearance and a more compact overall structure, meeting the design requirements of miniaturized air deflector size and simple and youthful design. When in the open position, the first air deflector 2 and the second air deflector 3 extend out of the main air deflector 1, which can increase the smoke collection area of ​​the air deflector and achieve a better oil fume absorption effect.

[0054] The deflector drive assembly also includes a sliding connection device, such as Figures 5 to 8As shown, 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 to the main air guide plate 1, and the other is fixed to the first air guide plate 2, ensuring that the first air guide plate 2 can move relative to the main air guide plate 1 without separating from the main air guide plate 1. Preferably, the sliding post 41 and the sliding rail 42 are respectively arranged near the edges of the main air guide plate 1 and the first air guide plate 2, so that the first air guide plate 2 can extend as far as possible from the main air guide plate 1, thereby increasing the smoke collection area and more thoroughly absorbing the oil smoke.

[0055] The slide post 41 is at least partially disposed within the slide rail 42. When the drive rod 121 of the drive device 12 pushes or pulls the stopper 21, the slide post 41 can move along the extension direction of the slide rail 42, thereby achieving translational movement of the first air deflector 2 relative to the main air guide 1. Both ends of the slide rail 42 are sealed to prevent the slide post 41 from dislodging at either end.

[0056] The slide rail 41 includes a connected limiting slide 411 and a connecting post 412. The slide rail 42 is a slot-like structure with an elongated hole 421 defined on one side. The limiting slide 411 is wider than the connecting post 412 and is located within the slot and restrained by the edge of the slot, preventing it from slipping out of the elongated hole 421. The connecting post 412 partially protrudes from the elongated hole 421, connecting to the main air guide plate 1 or the first air guide plate 2, thereby connecting the main air guide plate 1 and the first air guide plate 2. When pushed by an external force, the connecting post 412 can move along the extension direction of the elongated hole 421, causing the first air guide plate 2 to translate relative to the main air guide plate 1.

[0057] To maintain the first air deflector 2 in the closed position when pushed by the drive device 12, a locking structure is formed between the slide post 41 and the slide rail 42. This locking structure is capable of bearing at least the combined weight of the first air deflector 2 and the second air deflector 3. Only when the drive device 12 begins to apply a thrust to the first air deflector 2, and the sum of the thrust applied by the drive device 12 and the combined weight of the first and second air deflectors 2 and 3 exceeds the force the locking structure can bear, will the locking structure unlock and the slide post 41 begin to move along the extension direction of the slide rail 42.

[0058] The specific structure of the locking structure is not limited. Preferably, the limiting slide 411 is in an I-shape, with limiting recesses 413 formed on both sides of the limiting slide 411. A slide positioning assembly is provided on the end of the slide rail 42 away from the second air deflector 3. The slide positioning assembly includes a positioning protrusion 422 provided on the inner wall of the groove of the slide rail 42, a positioning adjustment member 423 provided on the outer side of the slide rail 42, and a positioning elastic member 424 connected between the positioning protrusion 422 and the positioning adjustment member 423. The positioning protrusion 422 is preferably hemispherical. When the driving force is sufficient, the positioning protrusion 422 can slide smoothly out of the limiting recess 413, avoiding complete jamming between the positioning protrusion 422 and the limiting recess 413.

[0059] When the positioning protrusion 422 is engaged with the limiting recess 413, the limiting slide 411 is fixed in the slide rail 42, and the first and second air deflectors 2 and 3 remain stationary relative to the main air deflector 1. When a force greater than or equal to a set value is applied to the slide post 41, the positioning protrusion 422 is pushed to the sides, and the positioning elastic member 424 is compressed until the positioning protrusion 422 is removed from the limiting recess 413. The limiting slide 411 can then move in the slide rail 42 along the extension direction of the slide rail 42, thereby achieving movement of the first air deflector 2 relative to the main air deflector 1. The sum of the weights of the first and second air deflectors 2 and 3 is less than the thrust force pushing the positioning protrusion 422 to move sideways, preventing the first air deflector 2 from initially sliding.

[0060] like Figure 9 As shown, a baffle 122 is preferably provided on the driving rod 121. Figure 10 and Figure 11 As shown, the limiting member 21 includes two parallel limiting posts 211. When the baffle 122 passes between the two limiting posts 211, the drive rod 121 can push the first air deflector 2 into place. After the baffle 122 passes between the two limiting posts 211, the drive rod 121 no longer applies force to the first air deflector 2. While the drive rod 121 pushes the second air deflector 3 to rotate, the first air deflector 2 does not move with the drive rod 121.

[0061] Each limiting column 211 is respectively provided with a limiting protrusion 212, a limiting adjustment member 213, and a limiting elastic member 214 provided between the limiting protrusion 212 and the limiting adjustment member 213. The limiting elastic member 214 can be a spring, a spring, a torsion spring or other devices with elastic deformation capabilities. The limiting adjustment member 213 is fixed on the limiting column 211, so one end of the limiting 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. When the external force is removed, the limiting elastic member 214 can push the limiting protrusion 212 in the opposite direction to achieve the reset of the limiting protrusion 212.

[0062] The two limiting protrusions 212 on the two limiting posts 211 are arranged opposite each other, allowing the drive rod 121 to pass between the two limiting posts 211 during extension and retraction. When the drive rod 121 passes between the two limiting posts 211, the baffle 122 will collide with the limiting protrusions 212. When the impact force of the baffle 122 is strong enough, the limiting protrusions 212 will move in the direction of compressing the limiting elastic member 214 until the baffle 122 passes between the two limiting posts 211.

[0063] The force causing the limiting protrusion 212 to move sideways is set to be greater than the force causing the positioning protrusion 422 to move sideways, so when the driving rod 121 hits the limiting member 21 during the extension process, the positioning protrusion 422 will move sideways until the positioning protrusion 422 withdraws from the limiting recess 413, and the limiting slide 411 moves in the slide rail 42 along the extension direction of the slide rail 42, causing the first air guide plate 2 to move to the bottom end relative to the main air guide plate 1; after the first air guide plate 2 can no longer move relative to the main air guide plate 1, all the force on the driving rod 121 is applied to the limiting member 21 until the limiting protrusion 212 moves sideways, the baffle 122 passes between the two limiting columns 211, and the driving rod 121 accurately hits the force-applying seat 31.

[0064] When the driving rod 121 hits the limit piece 21 during the contraction process, it will first push the limit slide 411 to slide in the slide rail 42 until the positioning protrusion 422 is again engaged in the limit recess 413, and then the force applied by the baffle 122 on the limit piece 21 increases to be sufficient to push the limit protrusion 212 to move sideways, and the baffle 122 passes between the two limit columns 211 and retracts to its original position.

[0065] The position limiter 21 allows the drive rod 121 to move the first air deflector 2 when needed. However, the drive rod 121 and the first air deflector 2 are not connected. When the drive rod 121 needs to rotate the second air deflector 3, the drive rod 121 disengages from the first air deflector 2, and the first air deflector 2 does not move with the drive rod 121. In other words, a single drive rod 121 can drive both the first and second air deflectors 2 and 3, making it more convenient and simpler to use. The drive rod 121 only needs to move linearly to drive the first air deflector 2 to move and the second air deflector 3 to rotate, resulting in a faster response speed for the first and second air deflectors 2 and 3.

[0066] like Figure 5 and Figure 12As shown, a hinge 5 is preferably connected between the first air deflector 2 and the second air deflector 3. The hinge 5 includes a sub-hinge 52 and a main hinge 53 connected by a hinge post 51. One of the sub-hinge 52 and the main hinge 53 is fixed to the first air deflector 2, and the other is fixed to the second air deflector 3. The sub-hinge 52 and the main hinge 53 can rotate about the hinge post 51, thereby achieving the connection between the first air deflector 2 and the second air deflector 3 without affecting the rotation of the second air deflector 3 relative to the first air deflector 2, and the overall structure is more stable.

[0067] In order to keep the first air guide plate 2 and the second air guide plate 3 in the same plane when the driving rod 121 is not pushed, magnetic parts 54 are respectively provided on the sub-hinge 52 and the main hinge 53. After the magnetic parts 54 of the sub-hinge 52 and the magnetic parts 54 of the main hinge 53 are attracted, the first air guide plate 2 and the second air guide plate 3 are in the same plane, and the sub-hinge 52 or the main hinge 53 connected to the second air guide plate 3 will not sag due to the gravity of the second air guide plate 3.

[0068] like Figure 4 、 Figure 5 、 Figure 13 and Figure 14 As shown, the force-applying seat 31 includes a seat body 311, which is provided with a connecting member 312, a through hole 314, and a relay member 315. The seat body 311 is connected to the second air deflector 3 via the connecting member 312, ensuring that when the drive rod 121 strikes the relay member 315, the second air deflector 3 can move synchronously with the seat body 311. A hinge 313 is fixedly provided on the first air deflector 2, and the seat body 311 is mounted on the hinge 313 through the through hole 314. When the drive rod 121 strikes the seat body 311, the seat body 311 can rotate about the hinge 313 until the second air deflector 3 tilts to a set angle relative to the first air deflector 2. The relay 315 is disposed on the side of the seat body 311 close to the driving rod 121 . When the driving rod 121 hits the seat body 311 , the driving rod 121 contacts the relay 315 , ensuring that the impact force on the seat body 311 is more stable.

[0069] After the baffle 122 passes through between the two limit columns 211, the end 123 of the driving rod 121 will hit the relay member 315, thereby causing the seat body 311 and the second air guide plate 3 to rotate as a whole around the hinge 313, and the magnetic member 54 of the sub-hinge 52 and the magnetic member 54 of the main hinge 53 are separated; when the driving rod 121 is retracted, under the pulling force of the driving rod 121 or under the action of the dead weight of the second air guide plate 3, the second air guide plate 3 is reset, and the magnetic member 54 of the sub-hinge 52 and the magnetic member 54 of the main hinge 53 are attracted again.

[0070] The relay member 315 is preferably spherical, and the end 123 of the driving rod 121 is preferably a hemispherical concave surface. The spherical relay member 315 can be embedded in the end 123 and roll in the end 123, avoiding the relay member 315 from being separated from the end 123 of the driving rod 121 due to the movement of the relay member 315 with the seat body 311, thereby ensuring the smooth movement of the second air guide plate 3.

[0071] The relay 315 is magnetically connected to the end 123 of the drive rod 121. When the drive rod 121 retracts, it pulls the relay 315 to move synchronously, resetting the seat body 311. This eliminates the need for a separate reset drive device for the seat body 311, resulting in a simpler overall structure, lower costs, and faster reset of the seat body 311.

[0072] By inserting the hinge 313 into the through hole 314, the first air deflector 2 and the second air deflector 3 are hingedly connected. The air deflector assembly can be provided with no hinge 5. Instead, the hinge 313 and the base body 311 are used to connect the first air deflector 2 and the second air deflector 3. This simplifies the overall structure and makes it easier to set parameters such as the distance between the hinge 313 and the first air deflector 2, the distance between the through hole 314 and the relay 315, and the distance between the connector 312 and the through hole 314. The air deflector assembly can also be provided with one or more hinges 5 to ensure a stable connection between the first air deflector 2 and the second air deflector 3. However, in this case, the distance between the hinge 313 and the first air deflector 2, the distance between the through hole 314 and the relay 315, and the distance between the connector 312 and the through hole 314 need to be matched with the size of the hinge 5 to avoid interference between the hinge 5 and the base body 311 when the base body 311 rotates around the hinge 313 due to size mismatch. In order to reduce the difficulty of setting the parameters of the seat body 311 , the hinge 313 and the hinge 5 , the connecting member 312 may be slidably connected to the second air guide plate 3 .
