[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0035] As mentioned in the background technology, the range hood 1000 is an appliance used in the kitchen, and its main function is to absorb the fumes generated during cooking and keep the kitchen air fresh. The range hood 1000 is usually installed above the stove, and the fumes are sucked in and filtered by a fan and then discharged outdoors.

[0036] In the prior art, some range hoods 1000 absorb smoke from cookware at different heights by adjusting the height of an air inlet located on one side. However, due to the thermodynamic effect of smoke, smoke usually tends to move upward. When the air volume is insufficient, it is difficult for the air inlet located on one side to completely inhale the smoke, thereby affecting the smoking effect. In addition, the length of the air flow channel changes after adjusting the different heights, thereby affecting the suction flow rate, which in turn affects the smoking effect.

[0037] In view of this, please refer to Figure 1-Figure 3 The range hood 1000 provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0038] A range hood 1000 is provided in an embodiment of the utility model. The range hood 1000 can draw smoke from cookware. The range hood 1000 not only optimizes the smoke extraction performance of the range hood 1000, but also improves the operational convenience and cleaning efficiency, thereby providing a user with a more efficient, smarter, and easier-to-maintain kitchen environment.

[0039] The range hood 1000 includes a body 100, a fan 200 and a foldable smoke guide 300. The fan 200 is disposed on the body 100 and is used to discharge smoke in the body 100 out of the body 100. The foldable smoke guide 300 is foldably disposed on the body 100. The foldable smoke guide 300 is used to be close to the smoke source when unfolded so that the smoke can flow into the body 100 through the foldable smoke guide 300.

[0040] In this way, by getting close to the smoke source, the smoke generated during the cooking process can be effectively captured, reducing the leakage of smoke. Even when the air volume is insufficient, the smoking efficiency can be improved, thereby improving the smoking effect.

[0041] Of course, when there is no need to extract smoke, the foldable smoke guide 300 can be in a folded state (which can also be understood as a retracted state), and the foldable smoke guide 300 can be away from the cookware.

[0042] Specifically, in this embodiment, the foldable smoke guide 300 includes a folding plate 320 and a transparent plate 310. The transparent plate 310 can be slidably arranged on the body 100. The transparent plate 310 and the folding plate 320 are connected. The transparent plate 310 and the folding plate 320 jointly surround the smoke outlet channel. The smoke channel is connected to the body 100. The folding plate 320 can be foldably arranged on the body 100. The folding plate 320 is used to be close to the smoke source when unfolded so that the smoke can flow into the body 100 through the folding plate 320.

[0043] The transparent plate 310 allows the user to clearly observe the cooking process while cooking.

[0044] The folding plate 320 is in a U-shaped structure, and the transparent plate 310 is connected to the opening of the folding plate 320 of the U-shaped structure, which is equivalent to the transparent plate 310 and the folding plate 320 together forming a square enclosure structure, and a smoke channel is defined in the square enclosure structure.

[0045] Of course, in other embodiments, the transparent plate 310 and the folding plate 320 can also together form an enclosure structure of other shapes, such as a circular enclosure structure.

[0046] In this embodiment, the principle of folding or unfolding the folding plate 320 can refer to the principle of folding or unfolding of the existing bellows, which will not be described in detail here.

[0047] The foldable smoke guide 300 also includes a first rod 330 and a second rod 340. The first rod 330 is connected to the lower side of the transparent plate 310. The second rod 340 can be understood as a U-shaped rod. The second rod 340 is connected to the lower side of the folding plate 320. The lower side of the folding plate 320 is connected to the lower part of the body 100. The two ends of the first rod 330 are vertically connected to the two ends of the second rod 340.

[0048] It is easy to understand that the first rod 330 , the second rod 340 , the transparent plate 310 and the folding plate 320 can together form a square enclosure structure.

[0049] Specifically, in order to facilitate the folding or unfolding of the foldable smoke guide 300, the smoke machine 1000 also includes a pull rope 410, a retractable roller 420 and a driving member 430. The retractable roller 420 is rotatably connected to the body 100, and the driving member 430 is connected to the retractable roller 420. The pull rope 410 is simultaneously connected to the retractable roller 420 and the transparent plate 310. The driving member 430 here can be a driving motor.

[0050] The driving member 430 is used to drive the reel 420 to rotate and reel in the pull rope 410, so that the transparent plate 310 rises and the folding plate 320 is folded, and the foldable smoke guide 300 can be away from the cookware. Alternatively, the driving member 430 is used to drive the reel 420 to rotate and unwind the pull rope 410, so that the transparent plate 310 descends and the folding plate 320 unfolds. The foldable smoke guide 300 is close to the smoke source and can effectively capture the oil smoke generated during the cooking process, reduce the leakage of smoke, and improve the smoking efficiency even when the air volume is insufficient, thereby improving the smoking effect.

[0051] In order to facilitate the cleaning of the transparent plate 310, in this embodiment, the range hood 1000 also includes a wiping block 510, which is arranged on the body 100. The wiping block 510 is used to contact the inner wall of the transparent plate 310. Part of the inner wall of the transparent plate 310 and the inner wall of the folding plate 320 together define a smoke channel.

[0052] In order to ensure that the wiping block 510 can always be in contact with the inner wall of the transparent plate 310 and improve the cleaning effect, the range hood 1000 also includes an elastic member 520 and a top rod 530. The top rod 530 is slidably disposed in the body 100. One end of the top rod 530 is connected to the wiping block 510, and the elastic member 520 elastically connects the other end of the top rod 530 to the body 100.

[0053] The elastic member 520 may be a spring. Specifically, the spring may be sleeved on the end of the top rod 530 . The elastic force of the elastic member 520 may keep the wiping block 510 in contact with the inner wall of the transparent plate 310 .

[0054] In order to facilitate the collection of oil stains, in this embodiment, the range hood 1000 also includes an intercepting guide plate 600, an oil drain pipe 700, a smoke exhaust pipe 800 and an oil box 900. The intercepting guide plate 600 is arranged in the body 100, and the intercepting guide plate 600 is inclinedly arranged in the body 100. The intercepting guide plate 600 is provided with a smoke hole, and the smoke hole is connected to the smoke channel. The oil box 900 is arranged at the bottom of the body 100, the oil drain pipe 700 is connected to the lower end of the fan 200, and the smoke exhaust pipe 800 is connected to the upper end of the fan 200. The height of the oil drain pipe 700 is greater than the height of the intercepting guide plate 600, wherein the fan 200 is used to suck the smoke through the smoke hole.

[0055] In addition, one side of the interception guide plate 600 is connected to the inner wall of the body 100. Since the interception guide plate 600 is arranged obliquely in the body 100 and the interception guide plate 600 is provided with a smoke hole, it can not only guide the smoke to enter the body 100 and be sucked by the fan 200, but also the interception guide plate 600 can intercept part of the oil. By obliquely setting the interception guide plate 600 in the body 100, the oil can flow along the inner wall of the body 100 under the action of gravity into the oil box 900 at the bottom of the body 100.

[0056] It should be noted that the number of smoke holes can be multiple, and all the smoke holes can be evenly distributed on the interception guide plate 600.

[0057] The smoke exhaust pipe 800 can be connected to the fan 200 to facilitate the discharge of the oil sucked by the fan 200 out of the body 100. The oil drain pipe 700 is located above the oil box 900. The height of the oil drain pipe 700 is also greater than the height of the interception guide plate 600. The oil drain pipe 700 is convenient for collecting oil stains on the fan 200, so that the oil stains can pass through the oil drain pipe 700, and then pass through the inner wall of the body 100 and flow into the oil box 900 through the smoke hole, or the oil stains can flow into the oil box 900 after passing through the oil drain pipe 700 and the smoke hole.

[0058] According to a range hood 1000 provided in this embodiment, the working principle of the range hood 1000 is as follows:

[0059] When in use, when the fan 200 is turned on, the fan 200 draws out air, thereby allowing the smoke to pass through the interception guide plate 600 and then continue to enter the body 100 and be discharged to the smoke pipe through the fan 200. After the interception guide plate 600 intercepts the oil stains in the smoke to a certain extent, the oil stains flow down to the oil box 900 under the action of gravity for collection, and the oil stains on the fan 200 also flow down to the oil box 900 through the oil discharge pipe 700 for collection. When the fan 200 is turned on, the power motor drives the reel 420 to rotate, and the reel 420 unwinds the pull rope 410, and then the transparent plate 310 descends, and the descent of the transparent plate 310 drives the first rod 330 to descend. When the first rod 330 descends, at the same time, the second rod 340 descends and drives the folding plate 320 to unfold, thereby forming a square enclosure structure around the bottom of the body 100. In conjunction with the transparent plate 310, the user can observe the cooking situation through the transparent plate 310. When the folding plate 320 is unfolded, the square enclosure structure can be close to the smoke source, and the smoke can enter the body 100 through the smoke channel, thereby preventing the smoke from leaking. When use is completed, the power motor reels the pull rope 410 to make the transparent plate 310 rise, the folding plate 320 folds, the foldable smoke guide 300 can be away from the pot, and when the transparent plate 310 rises, the wiping block 510 can wipe the inner wall of the transparent plate 310, thereby keeping the transparent plate 310 clean.

[0060] In summary, the range hood 1000 provided in this embodiment has at least the following advantages:

[0061] 1. Enhanced smoking effect: By providing an enclosure structure with a smoke passage under the machine body 100, the oil smoke generated during cooking can be effectively captured, and the smoke leakage can be reduced, thereby improving the smoking efficiency even when the air volume is insufficient.

[0062] 2. Good oil and dirt separation and collection effects: The design of the interception guide plate 600 not only guides the smoke into the machine body 100, but also intercepts part of the oil and dirt, allowing it to flow into the oil box 900 along the direction of gravity, which is convenient for centralized cleaning. At the same time, the oil and dirt on the fan 200 can also be collected through the oil drain pipe 700, reducing the difficulty and frequency of cleaning.

[0063] 3. Operational convenience: The lifting mechanism of the transparent plate 310 allows the user to clearly observe the cooking process while cooking. At the same time, when not in use, the transparent plate 310 can be automatically raised by a driving motor and cleaned by the wiping block 510, thereby maintaining the cleanliness of the transparent plate 310 and improving the user experience.

[0064] 4. Automatic operation: The power motor controls the lifting and lowering of the transparent plate 310 and the unfolding and folding of the folding plate 320, thereby realizing automatic operation, simplifying the user's operation steps, and improving the intelligence level of the equipment.

[0065] 5. Easy cleaning: The design of the wiping block 510 automatically cleans the inner wall of the transparent plate 310 when the transparent plate 310 rises, reducing the need for manual cleaning by the user and making maintenance more convenient and quick.

[0066] 6. Spatial adaptability: The enclosure structure composed of the transparent plate 310 and the folding plate 320 can be adjusted according to actual needs to adapt to different cooking scenes and space sizes, thereby improving the flexibility and applicability of the range hood 1000.

[0067] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
