[0031] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0032] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0033] Example 1:

[0034] A smoke collecting assembly, referring to Figures 1 to 6 , mainly used for gathering smoke and collecting oil smoke, which includes a smoke collecting shell 1, a first smoke collecting chamber 11, a second smoke collecting chamber 12, a smoke baffle 2, a first drive mechanism 3 and a second drive mechanism 4, wherein the first smoke collecting chamber 11 is located in the smoke collecting shell 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 shell 1, and the first smoke outlet 11b is formed on the top of the smoke collecting shell 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 two opposite sides of the smoke collecting shell 1. 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. On the other hand, it can improve the coordination of the appearance of the smoke collecting assembly and improve its aesthetics.

[0035] 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.

[0036] 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.

[0037] In this 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 in both directions 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 greater the width of the smoke baffle 2 sliding out in the horizontal direction relative to the first smoke inlet 11a, the stronger its smoke gathering effect.

[0038] 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 collection height range of the first smoke inlet 11a.

[0039] 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.

[0040] 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.

[0041] In this embodiment, the smoke baffle 2 is controlled by the first driving mechanism 3 to slide in two directions in the horizontal direction to adjust the horizontal smoke collecting width of the smoke baffle 2 for the first smoke inlet 11a, and because the smoke baffle 2 has flexibility and resilience, the second driving mechanism 4 controls the smoke baffle 2 to bend downward at the part 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, it can increase the smoke collecting range of the smoke collecting assembly, 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 generous, and helps to improve the overall aesthetics of the kitchen.

[0042] In this 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 the smoke baffle 2 is slidably embedded in the slot 13. The smoke baffle 2 can be completely hidden in the smoke collecting shell 1, making the appearance of the smoke collecting shell 1 more concise, reducing the space occupied by the smoke collecting component in the kitchen, and helping to improve the commercial value of the smoke collecting component.

[0043] In this embodiment, the slot 13 is provided from the outside to the inside on 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 oil stains generated in the range hood from dripping into the first smoke collecting cavity 11, and further preventing oil stains from dripping from the first smoke inlet 11a to contaminate the cooking area. In addition, since oil stains 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 stains on the top surface of the smoke baffle 2 from contaminating the slot 13, an oil suction assembly 6 is provided at the second opening 13b of the slot 13. The oil suction assembly 6 is used to absorb the oil stains on the top surface of the smoke baffle 2 as it slides.

[0044] 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 from dripping from the first smoke collecting cavity 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 of the first smoke inlet 11a, thereby increasing the smoke collecting range of the first smoke inlet 11a and improving the smoking efficiency.

[0045] In this embodiment, the oil suction assembly 6 is detachably connected to the second opening 13b of the slot 13. Once the oil suction assembly 6 has absorbed sufficient oil, it can be removed from the smoke collector housing 1. This allows the assembly 6 to be cleaned or replaced to maintain its effective oil absorption. Furthermore, the oil suction assembly 6 is positioned at the upper edge of the second opening 13b of the slot 13 and covers the width of the smoke baffle 2, ensuring that it can fully absorb oil from the top surface of the smoke baffle 2.

[0046] 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 is in contact with the top surface of the smoke shield 2. That is, when the smoke shield 2 slides, the oil suction cylinder 62 is driven by friction to roll. During rolling, the oil suction cylinder 62 can quickly and extensively contact the top surface of the smoke shield 2, resulting in high oil suction efficiency of the oil suction assembly 6. The oil suction cylinder 62 can be made of a material capable of absorbing oil, such as sponge or silicone.

[0047] In this embodiment, the first drive mechanism 3 includes a driver 31 mounted on the smoke collector 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 deflector 2 has a mating structure 21 extending along its sliding direction, and the transmission member 33 engages with the mating structure 21. Specifically, the driver 31 includes a plurality of circumferentially spaced rods, and the mating structure 21 includes a plurality of slots spaced along the sliding direction of the smoke deflector 2. The rods engage with the corresponding slots. During operation, the rotating rods drive the smoke deflector 2 to move.

[0048] In this embodiment, the second drive mechanism 4 comprises a telescopic drive rod, one end of which is pivotally connected to the smoke collector housing 1 and the other end of which is pivotally connected to the front end of the smoke deflector 2. The telescopic drive rod is electrically driven. Furthermore, the ends of the telescopic drive rod are connected to the smoke collector housing 1 and the smoke deflector 2, respectively, via a pin and a mounting bracket.

[0049] 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. 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.

[0050] 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.

[0051] 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.

[0052] 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 component.

[0053] In this embodiment, two partitions 14 are provided 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 airflow 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.

[0054] In this embodiment, the smoke collection assembly further includes an oil cup 5, which is disposed below the second smoke inlet 12a. This means that the oil cup 5 can collect oil dripping from the second smoke outlet 12b, preventing it 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 oil smoke to enter the second smoke collection cavity 12, ensuring that oil smoke can smoothly enter the second smoke collection cavity 12 from the second smoke outlet. Furthermore, the vertical projection of the second smoke outlet 12b is within the horizontal coverage of the oil cup 5, ensuring that there is sufficient space on the oil cup 5 to accommodate any oil dripping, preventing it from dripping into the cooking area.

[0055] The oil cup 5 comprises a horizontally arranged oil collection pan 51, a fence 52 extending upward from the edge of the oil collection pan 51, and at least one connector 53. One end of the connector 53 is connected to the oil collection pan 51 or the fence 52, and the other end is connected to the inner wall of the second smoke collection chamber 12. The structure of the oil collection pan 51 and the fence 52 ensures that the oil cup 5 can collect oil. Furthermore, the connector 53 is detachably connected to the inner wall of the second smoke collection chamber 12, allowing the user to remove the oil cup 5 to clean the collected oil.

[0056] Example 2:

[0057] A range hood includes the smoke collecting assembly and a fan assembly 7 in Example 1. The fan assembly 7 includes a fan housing 71 connected to the top of the smoke collecting housing 1 and an induced draft fan 72 arranged in the fan housing 71.

[0058] 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 above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
