[0034] Example 1,
[0035] A smoke collection device, used in a kitchen environment, is mainly used to collect and guide the cooking fumes generated by the stovetop into the range hood. (Refer to...) Figures 1 to 13The base g has a reserved groove g1, and the reserved groove g1 forms an opening g2 on the base surface. In this embodiment, the base g is set as a wall, and the base surface is the wall surface. Of course, the base g can also be set as other structures, such as housings, equipment, and other carriers. The smoke collection device includes a shell 1 with a smoke collection chamber inside and a drive component 2. The shell 1 is slidably set in the reserved groove g1. Smoke inlets 11 are provided on two sides of the shell 1 to draw the oil fumes on both sides of the shell 1 into the smoke collection chamber. The drive component 2 is used to drive the shell 1 to translate, so that the shell 1 has a stopped state hidden inside the base g and a working state exposed outside the base g.
[0036] When the housing 1 is in the off state, it is hidden inside the base g. At this time, the housing 1 does not occupy the space outside the base g, which makes the kitchen space appear more spacious and tidy. On the other hand, it avoids the housing 1 being exposed for a long time and being contaminated by oil fumes, dust and other substances in the kitchen, thus maintaining the cleanliness of the surface of the housing 1. At the same time, it reduces the risk of bumping or knocking to the user due to the housing 1 protruding from the base g, thus reducing safety hazards. When the housing 1 is in the working state, it is exposed outside the base g. At this time, the smoke inlets 11 on both sides of the housing 1 can draw the oil fumes on both sides of the housing 1 into the smoke collection chamber, keeping the kitchen environment clean.
[0037] In this embodiment, the drive unit 2 is used to drive the housing 1 to translate on the reserved slot g1, so that the user can switch the housing 1 between the stopped state hidden in the base g and the working state exposed outside the base g according to the usage needs. This satisfies the needs of saving space and cleaning, and also ensures the smoke extraction effect of the housing 1 during cooking.
[0038] In this embodiment, the front part of the housing 1 has a front plate 12. When the housing 1 is in the stopped state, the front plate 12 is flush with the base surface, that is, the front plate 12 and the base surface are on the same plane. At this time, the housing 1 and the base g form an integral whole, which has a better overall visual effect and helps to improve the product value. In addition, the edge of the front plate 12 is close to the edge corresponding to the opening g2, which can prevent dust, fumes or other pollutants in the kitchen from entering the reserved slot g1 from the opening g2 and contaminating the housing 1. When the housing 1 is started, the housing 1 gradually moves outward from the stopped state, that is, the state in which the front plate 12 is flush with the base surface, until it moves out of the base g for the maximum stroke. At this time, the smoke inlet 11 is completely exposed outside the base g.
[0039] In this embodiment, the lower wall of the reserved groove g1 is provided with two slide rails, which extend along the translational direction of the housing 1. The housing 1 is provided with two sliding members corresponding to each slide rail, which are located at the bottom of the housing 1 and are slidably connected to the slide rail. Here, the sliding member is designed to extend horizontally and protrude downwards, while the slide rail is designed to be a long strip-shaped locking structure that is recessed from top to bottom. That is, the slide rail has a groove extending along the translational direction of the housing 1, and the sliding member is slidably fitted into the groove. The cooperation structure between the slide rail and the sliding member can provide stable support for the housing 1 when it is in the working state, and also ensure the accuracy of the sliding direction of the housing 1.
[0040] In this embodiment, in order to improve the smoke extraction effect of the smoke inlet 11, a smoke guide plate 3 is provided at the smoke inlet 11. The smoke guide plate 3 is used to gather the oil fumes. The smoke guide plate 3 can slide vertically relative to the housing 1. When the smoke guide plate 3 slides upward, it gradually flips outward. After the smoke guide plate 3 flips outward, a smoke inlet channel can be formed between it and the smoke inlet 11 to reduce the escape and diffusion of oil fumes. Here, the vertical sliding of the smoke guide plate 3 is driven by the driving component 2.
[0041] Specifically, the drive assembly 2 includes a drive mechanism 21 and a transmission mechanism 22. The transmission mechanism 22 includes a first moving gear 221, a second moving gear 222, and a first output wheel 223 that can move in the left and right directions. It also includes a second output wheel 224 that is fixed in position and a driver 225. The first output wheel 223 and the second output wheel 224 are used to drive the vertical sliding of the smoke guide plates 3 on both sides. The drive mechanism 21 is used to synchronously drive the first moving gear 221 and the second moving gear 222 to rotate and move in the same direction, so that the first moving gear 221 and the first output wheel 223 are engaged, or the second moving gear 222 and the second output wheel 224 are engaged. The driver 225 is used to drive the first output wheel 223 to move and engage with the first moving gear 221.
[0042] When the first moving gear 221 and the first output wheel 223 are engaged, the first output wheel 223 can drive the smoke guide plate 3 on one side to slide vertically. When the second moving gear 222 and the second output wheel 224 are engaged, the second output wheel 224 can drive the smoke guide plate 3 on the other side to slide vertically. Furthermore, since the driver 225 can drive the first output wheel 223 to move and engage with the first moving gear 221, the second moving gear 222 can also engage with the second output wheel 224 when the first moving gear 221 and the first output wheel 223 are engaged. Based on this, the drive assembly 2 can control the vertical sliding of one side of the smoke guide plate 3 separately, or control the vertical sliding of both sides of the smoke guide plate 3 simultaneously. That is, the user can selectively use the drive mechanism 21 to control the smoke guide plate 3 on one side or open the smoke guide plates on both sides of the housing 1 according to actual needs. For example, when only one side of the stove is cooking, only the smoke guide plate 3 on that side can be moved, while the smoke guide plate 3 on the other side is closed, thereby avoiding unnecessary noise and energy consumption.
[0043] In this embodiment, the drive mechanism 21 includes a drive motor 211 configured as a dual-head motor, two rotating shafts 212 mounted on the drive motor 211, and a first fixed gear 213 and a second fixed gear 214 respectively connected to the two rotating shafts 212. The two rotating shafts 212 are respectively installed at both ends of the dual-head motor. When the dual-head motor is working, it drives the two rotating shafts 212 to rotate synchronously, thereby driving the first fixed gear 213 and the second fixed gear 214 respectively installed on the two rotating shafts 212 to rotate. Here, the first fixed gear 213 meshes with the first moving gear 221 and both are helical gears, and the second fixed gear 214 meshes with the second moving gear 222 and both are helical gears. The helical gears, specifically the first fixed gear 213 and the second fixed gear 214, have the same structure, as do the first moving gear 221 and the second moving gear 222. Since the first fixed gear 213 and the first moving gear 221 mesh and are both helical gears, the first fixed gear 213 generates a lateral thrust on the first moving gear 221 when it rotates, causing the first moving gear 221 to translate. Therefore, when the dual-head motor is working, the rotating first fixed gear 213 and the second fixed gear 214 can push the first moving gear 221 and the second moving gear 222 to move in the same direction. The direction of movement of the first moving gear 221 and the second moving gear 222 can be controlled by the rotation direction of the dual-head motor.
[0044] In this embodiment, the surfaces of the first output wheel 223 and the first moving gear 221 facing each other are respectively provided with a slot 230 and a tooth 229. The engagement of the slot 230 and the tooth 229 allows the first output wheel 223 and the first moving gear 221 to be engaged. This engagement structure ensures that the first moving gear 221 can be tightly connected to the first output wheel 223, guaranteeing transmission accuracy. Furthermore, the first moving gear 221 can be installed on the first output wheel 223 by translating it, without the need for complex adjustments and calibrations. Correspondingly, the surfaces of the second output wheel 224 and the second moving gear 222 facing each other are respectively provided with a slot 230 and a tooth 229. The engagement of the slot 230 and the tooth 229 allows the second output wheel 224 and the second moving gear 222 to be engaged. In addition, the slots 230 and the teeth 229 are arranged circumferentially at intervals, resulting in a more balanced force distribution during engagement and thus better connection reliability.
[0045] In this embodiment, the drive mechanism 21 further includes two drive gears 215 respectively connected to two rotating shafts 212 and two racks g4 meshing with the two drive gears 215. The two racks g4 are spaced apart from each other and mesh with the corresponding drive gears 215 respectively. The racks g4 are disposed on the groove wall of the reserved groove g1 and extend along the translation direction of the housing 1. The racks g4 are fixedly connected to the upper groove wall of the reserved groove g1. The drive motor 211 is disposed on the top of the housing 1. When working, the dual-head motor rotates to drive the drive gears 215 connected to the rotating shafts 212 to rotate, so that the rotating drive gears 215 can move linearly along the extension direction of the racks g4, thereby driving the drive motor 211 to translate, and thus causing the housing 1 fixedly connected to the drive motor 211 to translate. The direction of movement of the housing 1 can be adjusted by changing the rotation direction of the dual-head motor.
[0046] Since the forward and backward translation of the housing 1 and the vertical movement of the smoke guide plate are both controlled by a dual-head motor, when the housing 1 is in the working state, in order to maintain the stability of the housing 1, it is necessary to avoid the dual-head motor driving the vertical lifting and lowering of the smoke guide plate and the translation of the housing 1 simultaneously. Therefore, the drive mechanism 21 also includes a bidirectional damper 216 sleeved on the rotating shaft 212. The drive gear 215 is connected to the bidirectional damper 216. Furthermore, the bidirectional damper 216 is set with a threshold torque. When the output torque of the drive motor 211 is greater than the threshold torque, the bidirectional damper 216 rotates. When the output torque of the drive motor 211 is less than the threshold torque, the bidirectional damper 216 does not rotate. Therefore, when the housing is in the working state, it is only necessary to adjust the output torque of the drive motor 211 to ensure that the drive gear 215 is in a fixed state when the rotating shaft 212 rotates.
[0047] In this embodiment, the cooperative structure of the drive mechanism 21 and the transmission mechanism 22 enables a single dual-head motor to control the outward rotation of the smoke guide plates 3 on both sides of the housing 1 and to control the outward rotation of the smoke guide plates 3 on both sides simultaneously. Furthermore, by setting a bidirectional damper 216 on the rotating shaft 212, the dual-head motor can also control the housing 1 to switch between a stopped state hidden inside the base g and a working state exposed outside the base g, which significantly simplifies the internal structure of this smoke collection device and facilitates manufacturing.
[0048] In this embodiment, the transmission mechanism 22 further includes a first shaft 227 extending in the left-right direction and a second shaft 228 extending in the left-right direction. A first moving gear 221 is slidably sleeved on the first shaft 227, a first output wheel 223 is fixedly sleeved on the first shaft 227, a second moving gear 222 is slidably sleeved on the second shaft 228, a second output wheel 224 is fixedly sleeved on the second shaft 228, and a driver 225 is slidably sleeved on the second shaft 228. The driver 225 is used to drive the first shaft 227 to slide in the left-right direction, thereby engaging the second output wheel 224 and the second moving gear 222. The driver 225 is configured to... A spring-loaded reset element 226 is provided to drive the second shaft 228 to reset. It should be noted that the driver 225 is a solenoid valve, and the spring-loaded reset element 226 is a spring. The spring is sleeved on the outer end of the first shaft 227. During operation, the solenoid valve can apply a continuous pushing force to the first shaft 227 in the left or right direction, causing the first shaft 227 to slide towards the first moving gear 221 until the first moving gear 221 engages with the first output wheel 223. During this period, the spring is compressed. When the solenoid valve cancels the pushing force applied to the first shaft 227, the spring force drives the first shaft 227 to reset.
[0049] In this embodiment, the smoke guide plate at the smoke inlet 11 is multi-layered, and the smoke inlet 11 is provided with a vertically extending movable slide rail 5 and a flip slide rail 6 inclined to the movable slide rail 5. The distance between the movable slide rail 5 and the flip slide rail 6 gradually decreases from bottom to top. The smoke guide plate 3 is slidably connected to the movable slide rail 5 and the flip slide rail 6 at the same time. The smoke guide plate driving mechanism 4 is used to drive multiple smoke guide plates 3 to slide along the movable slide rail 5, so that the smoke guide plate 3 gradually flips outward when sliding upward along the movable slide rail 5.
[0050] Specifically, the smoke guide plate 3 has a sliding pivot 34 extending forward and backward. The smoke guide plate 3 is connected to a mating part 35 with the sliding pivot 34 as the rotation center. The sliding pivot 34 is located near the top edge of the smoke guide plate. The sliding pivot 34 is slidably connected to the moving slide rail 5. The mating part 35 is slidably connected to the flipping slide rail 6. When the smoke guide plate 3 slides upward along the trajectory of the moving slide rail 5 and the flipping slide rail 6 under the drive of the smoke guide plate drive mechanism 4, the distance between the moving slide rail 5 and the flipping slide rail 6 gradually decreases from bottom to top. The mating part 35 will be subjected to an outward pushing force applied to it by the flipping slide rail 6, causing the mating part 35 to rotate during the upward sliding process, thereby pushing the smoke guide plate 3 to gradually flip outward when sliding upward.
[0051] In this embodiment, both the front and rear sides of the smoke inlet 11 are provided with a movable slide rail 5 and a flip slide rail 6. The two ends of the sliding shaft 34 are slidably connected to the corresponding movable slide rail 5. Both the front and rear sides of the smoke guide plate 3 are connected with mating parts 35, and the two mating parts 35 are slidably connected to the corresponding flip slide rail 6. The provision of movable slide rail 5 and flip slide rail 6 on both the front and rear sides of the smoke inlet 11 can improve the stability of the smoke guide plate during movement.
[0052] In this embodiment, the smoke guide plate 3 is upright when it is at its lowest position, and flips to its maximum angle when it is at its highest position. This allows the smoke guide plate 3 to move from its upright position at the lowest position to its flipped position at the maximum angle at the highest position. Therefore, the user can adjust the position and angle of the smoke guide plate 3 according to actual needs to achieve the best oil fume control effect.
[0053] In this embodiment, the smoke guide plate driving mechanism 4 is used to drive the smoke guide plate 31 located on the top layer. The other smoke guide plates are linked with the smoke guide plate 31 on the top layer, so that they slide vertically along the moving slide rail 5 synchronously with the smoke guide plate 31 on the top layer. The vertical sliding distance of the multiple smoke guide plates 3 gradually increases from top to bottom.
[0054] In this embodiment, the smoke guide plate driving mechanism 4 includes an output wheel driven to rotate by a drive source. The output wheel includes a first output wheel 223 and a second output wheel 224. A pull rope 41 is connected to the output wheel and is connected to the top-level smoke guide plate 31. The first output wheel 223 or the second output wheel 224 is connected to the pull rope 41. When the first output wheel 223 or the second output wheel 224 rotates under the drive of the drive motor 211, it drives the pull rope 41 to move. The pull rope 41 connects to the top-level smoke guide plate 31, thus enabling the top-level smoke guide plate 31 to move vertically. It should be noted that the drive source here is the drive motor 211 described in this embodiment.
[0055] In this embodiment, the top-level smoke guide plate 31 is equipped with a linkage pulley 43. The second-level smoke guide plate 32 is connected to a first linkage rope 45. The first linkage rope 45 is connected to the linkage pulley 43, and one end of the first linkage rope 45 is connected to the second-level smoke guide plate 32, while the other end is fixedly connected to the bottom of the housing 1. This allows the top-level smoke guide plate to rise vertically, driving the second-level smoke guide plate 32 to rise vertically as well. In this structure, refer to... Figure 8 The first linkage rope 45 moves a distance relative to the linkage pulley 43 that is twice the vertical rising height of the top layer of smoke guide plate 32, so that the vertical rising height of the second layer of smoke guide plate 32 from top to bottom is twice the vertical rising height of the top layer of smoke guide plate 31.
[0056] In this embodiment, refer to Figure 9 A fixed pulley 46 is provided at the smoke inlet 11. The third layer of smoke guide plate 33 from the top is connected to a second linkage rope 47. The second linkage rope 47 sequentially drives the linkage pulley 43 and the fixed pulley 46, and is connected to the top layer of smoke guide plate 31. When the top layer of smoke guide plate 31 rises vertically, it can drive the second linkage rope 47 to move, thereby driving the third layer of smoke guide plate 33 from the top to move. In this structure, the distance that the second linkage rope 47 moves relative to the linkage pulley 43 is three times the vertical rise height of the top layer of smoke guide plate 32, so that the vertical rise height of the second layer of smoke guide plate 32 from the top is three times the vertical rise height of the top layer of smoke guide plate 32.
[0057] In this embodiment, the smoke guide plate 3 at the smoke inlet 11 on one side of the housing 1 is generally configured as three layers, and the three layers of smoke guide plates 3 are arranged vertically in sequence.
[0058] In this embodiment, the housing 1 is provided with two oil filters 7, which are used to intercept grease from the fumes drawn in by the two smoke inlets 11. The housing 1 is provided with an oil box 8 below the two oil filters 7, which is used to collect the grease dripping from the two oil filters 7. It can intercept the grease from the fumes drawn in by the two smoke inlets 11 and collect it by the oil box 8, thereby preventing grease from falling on the stove and contaminating the stove.
[0059] In this embodiment, the oil mesh 7 gradually slopes towards the middle of the smoke collection chamber from the top edge to the bottom edge of the shell 1. The two oil meshes 7 are combined to form an inverted V-shaped structure. The surface of the oil mesh 7 is provided with a plurality of guide grooves 72 spaced apart from each other in the front-back direction. The grease intercepted on the oil mesh 7 can be guided into the oil box 8 under the guidance of the guide grooves 72.
[0060] In this embodiment, the top edge of the oil mesh 7 is connected to the top of the housing 1, and the bottom edge of the oil mesh 7 is connected to the oil box 8, so that the two oil meshes 7 and the oil box 8 form a separation structure. The separation structure divides the smoke collection chamber into an inner smoke gathering area and an outer smoke inlet area. The rear of the housing 1 is provided with a smoke exhaust port, and the smoke exhaust port corresponds to the smoke gathering area.
[0061] In this embodiment, the bottom edges of the oil box 8 and the two oil filters 7 are provided with multiple sets of connecting components 9. The movement of the oil box 8 relative to the oil filters 7 causes the connecting components 9 to switch between a locked state and an unlocked state. In the locked state, the oil box 8 and the oil filters 7 are tightly connected, which can prevent the oil box 8 from accidentally falling off or moving, thereby ensuring the normal operation and safety of the smoke collection device. In the unlocked state, the user can remove the oil box 8 from the oil filters 7 for cleaning or replacement.
[0062] In this embodiment, the bottom edge of the oil mesh 7 is provided with a first folded edge 71 extending outward from the oil mesh 7, and the top edges on both sides of the oil box 8 are provided with a second folded edge 81 extending outward from the oil box 8. The first folded edge 71 and the second folded edge 81 fit together. At this time, the contact surface between the first folded edge 71 and the second folded edge 81 forms a sealing structure, thereby preventing grease from leaking from between the oil box 8 and the bottom edge of the oil mesh 7.
[0063] The connecting assembly 9 includes a connecting groove 91 and a connector 92. One of the connecting groove 91 and the connector 92 is located on the first folded edge 71, and the other is located on the second folded edge 81. The connecting groove 91 includes an unlocking section and a locking section that are connected together. The connector 92 includes a connecting handle 921 and a locking part 922 connected to the connecting handle 921. The connecting handle 921 can pass through the unlocking section and the locking section, while the locking part 922 can pass through the unlocking section but cannot pass through the locking section. The connector 92 slides along the connection direction of the unlocking section and the locking section, so that the locking part 922 corresponds to the unlocking section or the locking section. When the locking part 922 corresponds to the unlocking section, the connecting assembly 9 is in the unlocked state. At this time, the user can remove the oil box 8 from the oil filter 7 to clean or replace the oil box 8. When the locking part 922 corresponds to the locking section, the connecting assembly 9 is in the locked state, ensuring a tight connection between the oil box 8 and the oil filter 7.
[0064] In this embodiment, the front end plate 12 of the housing 1 is provided with a window that allows the oil box 8 to pass through. The front end of the oil box 8 is provided with a handle structure 82. The handle is used to pull the oil box 8 in the front and back direction. The unlocking section and the locking section are connected in the front and back direction. When the user needs to remove the oil box 8 from the housing 1, he can pull the oil box 8 forward through the handle structure 82 so that the locking part 922 corresponds to the unlocking section. At this time, the oil box 8 is moved downward until the connecting part 92 disengages from the connecting groove 91. Then the oil box 8 can be pulled out from the window. This allows the oil box 8 to be removed from the housing 1 without removing the front end plate 12 of the housing 1, which is convenient.
[0065] Example 2,
