The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0036] Embodiment 1:

[0037] A smoke collecting assembly, referring to Figures 1 to 6 , mainly used for gathering smoke and collecting oil smoke, including a smoke collecting housing 1, a first smoke collecting chamber 11, a second smoke collecting chamber 12, a smoke baffle 2, a first driving mechanism 3 and a second driving mechanism 4, wherein the first smoke collecting chamber 11 is located in the smoke collecting housing 1, and has a first smoke inlet 11a and a first smoke outlet 11b, the first smoke inlet 11a is formed on the side of the smoke collecting housing 1, and the first smoke outlet 11b is formed on the top of the smoke collecting housing 1, and the oil smoke generated during cooking can enter the first smoke collecting chamber 11 from the first smoke inlet 11a and flow out from the first smoke outlet 11b. There are two first smoke collecting chambers 11, and the first smoke inlets 11a of the two first smoke collecting chambers 11 are respectively formed on the two opposite sides of the smoke collecting housing 1, and the smoke collecting assembly can gather smoke on both sides. On the one hand, the smoking range of the smoke collecting assembly can cover a wider cooking area, thereby reducing the escape of oil smoke, and on the other hand, it can improve the coordination of the appearance of the smoke collecting assembly and improve the aesthetics.

[0038] The second smoke collecting chamber 12 is located between the two first smoke collecting chambers 11, and the second smoke collecting chamber 12 has a second smoke inlet 12a formed at the bottom of the smoke collecting shell 1, and a second smoke outlet 12b formed at the top of the smoke collecting shell 1. The oil smoke generated during cooking can flow into the second smoke collecting chamber 12 from the second smoke inlet 12a located at the bottom of the smoke collecting shell 1, and flow out from the second smoke outlet 12b.

[0039] In this embodiment, the fumes generated by cooking can not only be absorbed by the second smoke inlet 12a located at the bottom of the smoke collecting shell 1, but also can be absorbed by the first smoke inlet 11a located on both sides of the smoke collecting shell 1, so that the smoke collecting assembly has a larger smoking range and can more effectively capture the fumes generated from the cooking area, thereby reducing the spread of fumes affecting kitchen hygiene and human health.

[0040] In the present embodiment, the smoke baffle 2 is slidably arranged inside the smoke collecting shell 1 and is located above the first smoke collecting chamber 11. The first driving mechanism 3 is used to drive the smoke baffle 2 to slide bidirectionally in the horizontal direction. Driven by the first driving mechanism 3, when the smoke baffle 2 slides outward, the smoke baffle 2 can effectively block the oil smoke in the horizontal width direction of the first smoke inlet 11a, thereby forcing the oil smoke to gather toward the first smoke inlet 11a, thereby increasing the smoke gathering width range, and the larger the width of the smoke baffle 2 sliding out in the horizontal direction relative to the first smoke inlet 11a, the stronger the smoke gathering effect.

[0041] In this embodiment, the second driving mechanism 4 is used to drive the portion of the smoke baffle 2 outside the first smoke collecting chamber to bend downward. When the portion of the smoke baffle 2 outside the first smoke collecting chamber bends downward, the bent portion can effectively block the escape of oil smoke in the vertical direction, forcing the oil smoke to gather toward the first smoke inlet 11a, thereby increasing the vertical smoke collecting height range of the first smoke inlet 11a.

[0042] It should be noted that when the smoke collecting assembly in this embodiment is Figure 2 When placed in the middle position, the horizontal smoke-collecting width refers to the smoke-collecting range of the first smoke inlet 11a in the left-right direction, and the vertical smoke-collecting height refers to the smoke-collecting range of the first smoke inlet 11a in the up-down direction.

[0043] In addition, it should be noted that the smoke shield 2 in this embodiment has bendability and resilience, and can bend and deform when subjected to external force, and can return to its original state after the external force is removed.

[0044] In this embodiment, the first driving mechanism 3 controls the smoke baffle 2 to slide bidirectionally in the horizontal direction to adjust the horizontal smoke collecting width of the smoke baffle 2 for the first smoke inlet 11a, and the smoke baffle 2 has bendability and resilience. The second driving mechanism 4 controls the smoke baffle 2 to bend downward outside the first smoke collecting chamber 11 to adjust the vertical smoke collecting height of the smoke baffle 2 for the first smoke inlet 11a. On the one hand, the smoke collecting range of the smoke collecting assembly can be increased, thereby improving the smoking efficiency of the smoke collecting assembly and reducing the escape of oil smoke. On the other hand, the smoke baffle has a simple structure and occupies a small space, which makes the appearance of the smoke collecting assembly more simple and elegant, and helps to improve the overall aesthetics of the kitchen.

[0045] The smoke collecting assembly of this embodiment is used during cooking. The horizontal movement distance and the downward bending degree of the smoke baffle 2 are controlled according to the smoke concentration at the first smoke inlet 11a, so that the smoke baffle 2 matches the corresponding posture to effectively collect the smoke, thereby improving the efficiency of the smoke being sucked into the first smoke inlet 11a and preventing the smoke from escaping.

[0046] More specifically, the smoke baffle 2 is set with multiple gears, and each gear is set with a different horizontal movement distance and downward bending degree. The smoke baffle 2 is controlled to be adjusted to the corresponding gear according to the oil fume concentration at the first smoke inlet 11a. The oil fume concentration can be detected by a smoke sensor, and the smoke baffle 2 is adjusted to the corresponding gear according to the oil fume concentration, making the adjustment more targeted.

[0047] In the present embodiment, a slot 13 extending in a horizontal direction is provided in the smoke collecting shell 1 above the first smoke collecting chamber 11, and a smoke baffle 2 is slidably embedded in the slot 13. The smoke baffle 2 can be completely hidden in the smoke collecting shell 1, so that the appearance of the smoke collecting shell 1 is more concise, and the occupation of the kitchen space by the smoke collecting component is reduced, which helps to improve the commercial value of the smoke collecting component.

[0048] In this embodiment, the slot 13 is set from the outside to the inside from one side of the smoke collecting housing 1, and has a first opening 13a corresponding to the first smoke inlet 11a and a second opening 13b corresponding to the first smoke outlet 11b, that is, the smoke baffle 2 can pass through the second opening 13b under the drive of the first driving mechanism 3 to block the first smoke outlet 11b, thereby preventing the oil generated in the range hood from dripping into the first smoke collecting cavity 11, and further preventing the oil from dripping from the first smoke inlet 11a to contaminate the cooking area. In addition, since the oil generated in the range hood will drip onto the top surface of the smoke baffle 2 after the smoke baffle 2 blocks the first smoke outlet 11b, in order to prevent the oil on the top surface of the smoke baffle 2 from contaminating the slot 13, an oil suction component 6 is provided at the second opening 13b of the slot 13, and the oil suction component 6 is used to absorb the oil on the top surface of the smoke baffle 2 when it slides.

[0049] In this embodiment, the smoke baffle 2 is controlled by the first driving mechanism 3 to slide in both directions in the horizontal direction. When the smoke collecting assembly is in a non-working state, the smoke baffle 2 is controlled to slide inward to cover the first smoke outlet 11b, thereby preventing oil stains from dripping from the first smoke collecting chamber 11 to the cooking area and maintaining the cleanliness of the cooking area; when the smoke collecting assembly is in a working state, the smoke baffle 2 is controlled to slide outward to adjust the horizontal smoke collecting width for the first smoke inlet 11a, thereby increasing the smoke collecting range of the first smoke inlet 11a and improving the smoking efficiency.

[0050] In this embodiment, the oil suction assembly 6 is detachably connected to the second opening 13b of the slot 13. When the oil suction assembly 6 absorbs enough oil, the oil suction assembly 6 can be removed from the smoke collecting housing 1, so that the oil suction assembly 6 can always have a good oil suction effect by cleaning or replacing the oil suction assembly 6. At the same time, the oil suction assembly 6 is arranged at the upper edge of the second opening 13b of the slot 13, and the oil suction assembly 6 can cover the width of the smoke baffle 2, ensuring that the oil suction assembly 6 can fully absorb the oil on the top surface of the smoke baffle 2.

[0051] The oil suction assembly 6 includes a rotating rod 61 and an oil suction cylinder 62 sleeved on the rotating rod 61, the rotating rod 61 is rotatably connected to the upper edge of the second opening 13b of the slot 13, the oil suction cylinder 62 and the top surface of the smoke baffle 2 are in contact, that is, when the smoke baffle 2 slides, the oil suction cylinder 62 can be driven to roll under the action of friction, and the oil suction cylinder 62 can contact the top surface of the smoke baffle 2 in a large area and quickly when rolling, and the oil suction assembly 6 has high oil suction efficiency. The oil suction cylinder 62 here can be made of materials that can absorb oil stains, such as sponge and silica gel.

[0052] In this embodiment, the first driving mechanism 3 includes a driver 31 disposed on the smoke collecting housing 1, a rotating shaft 32 driven by the driver 31, and a transmission member 33 connected to the rotating shaft 32. The bottom of the smoke shield 2 has a matching structure 21 extending along its sliding direction, and the transmission member 33 is engaged with the matching structure 21. Specifically, the driver 31 has a plurality of plug rods arranged at intervals along the circumferential direction, and the matching structure 21 includes a plurality of plug holes arranged at intervals along the sliding direction of the smoke shield 2. The plug rods are plugged and matched with the corresponding plug holes. When working, the rotating plug rods drive the smoke shield 2 to move.

[0053] In this embodiment, the second driving mechanism 4 includes a telescopic driving rod, one end of which is rotatably connected to the smoke collecting housing 1, and the other end of which is rotatably connected to the front end top of the smoke shield 2. The telescopic driving rod is electrically driven. In addition, both ends of the telescopic driving rod can be connected to the smoke collecting housing 1 and the smoke shield 2 through the structure of a pin shaft and a mounting seat.

[0054] In this embodiment, a groove portion 15 is formed on the side of the smoke collecting shell 1, which is recessed inward and passes through the bottom of the smoke collecting shell 1. The first smoke inlet 11a is located at the bottom of the groove portion 15. The groove portion 15 has an upper smoke barrier wall 15a corresponding to the top edge of the first smoke inlet 11a, and two side smoke barrier walls 15b corresponding to the two side edges of the first smoke inlet 11a respectively. The oil smoke flowing through the side of the smoke collecting shell 1 can be gathered to the first smoke inlet 11a by the upper smoke barrier wall 15a and the side smoke barrier wall 15b, that is, when the smoke barrier plate 2 does not extend out of the slot 13, the smoke collecting shell 1 itself has a certain smoke gathering effect, which can reduce the diffusion and escape of oil smoke in the air.

[0055] In this embodiment, the air intake direction of the first smoke collecting chamber 11 gradually tilts upward from the horizontal direction, which can guide the oil smoke flowing in from the first smoke inlet 11a to flow along a smoother path, reducing the resistance encountered by the oil smoke when flowing in the first smoke collecting chamber 11, thereby increasing the flow rate of the oil smoke in the first smoke collecting chamber 11.

[0056] In this embodiment, the cross-sectional area of ​​the first smoke collecting chamber 11 gradually decreases from the first smoke inlet 11a to the first smoke outlet 11b. When the oil smoke enters the first smoke collecting chamber 11 from the first smoke inlet 11a, the flow rate of the oil smoke gradually increases, so that the oil smoke can be quickly discharged from the first smoke outlet 11b, thereby improving the smoking efficiency of the smoke collecting assembly.

[0057] In this embodiment, the cross-sectional area of ​​the second smoke collecting chamber 12 gradually decreases from the second smoke inlet 12a to the second smoke outlet 12b. When the oil smoke enters the second smoke collecting chamber 12 from the second smoke inlet 12a, the flow rate of the oil smoke gradually increases, so that the oil smoke can be quickly discharged from the second smoke outlet 12b, which helps to improve the smoking efficiency of the smoke collecting assembly.

[0058] In this embodiment, two partitions 14 are arranged in the smoke collecting shell 1, and the two partitions 14 separate the second smoke collecting chamber 12 from the two first smoke collecting chambers 11, so that the oil smoke entering the first smoke collecting chamber 11 and the second smoke collecting chamber 12 can accurately flow out from their respective smoke outlets, avoiding air flow turbulence and mutual interference in different smoke collecting chambers; at the same time, the top of the smoke collecting shell 1 has an opening, and the two partitions 14 extend to the opening, dividing the opening into the second smoke outlet 12b and the two first smoke outlets 11b, that is, the partition 14 can keep the oil smoke always effectively moving in the first smoke collecting chamber 11 or the second smoke collecting chamber 12, thereby improving the smoking efficiency.

[0059] In this embodiment, the smoke collecting assembly further includes an oil cup 5, which is arranged below the second smoke inlet 12a, that is, the oil cup 5 can collect the oil stains dripping from the second smoke outlet 12b to prevent the oil stains from dripping into the cooking area. A gap is left between the edge of the oil cup 5 and the edge of the second smoke inlet 12a to allow the oil smoke to enter the second smoke collecting cavity 12, ensuring that the oil smoke can smoothly enter the second smoke collecting cavity 12 from the second smoke outlet. In addition, the projection of the second smoke outlet 12b in the vertical direction is located within the horizontal coverage of the oil cup 5, ensuring that there is enough space on the oil cup 5 to accommodate the oil stains that may drip, preventing the oil stains from dripping into the cooking area.

[0060] The oil cup 5 includes a horizontally arranged oil collecting pan 51, a fence 52 extending upward from the edge of the oil collecting pan 51, and at least one connecting member 53. One end of the connecting member 53 is connected to the oil collecting pan 51 or the fence 52, and the other end is connected to the inner wall of the second smoke collecting chamber 12. The structure of the oil collecting pan 51 and the fence 52 ensures that the oil cup 5 can collect oil. In addition, the connecting member 53 is detachably connected to the inner wall of the second smoke collecting chamber 12, and the user can clean the oil collected in the oil cup 5 by disassembling the oil cup 5.

[0063] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein.
