Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a countertop range hood. Background Technology

[0002] With the diversification of cooking methods today, the fumes produced by cooking pots in home hot pot and barbecue settings are a major source of health hazards. These fumes contain various harmful substances, including acrolein, benzene, formaldehyde, and crotonaldehyde, all of which are toxic and suspected carcinogens. Furthermore, the skin is the largest respiratory organ, and the fine particles of volatile oils produced by heating in these fumes can easily clog skin pores.

[0003] To solve the above problems, existing technology has invented a countertop range hood, which is placed next to the cooking pot, thereby effectively absorbing the oil fumes generated in the cooking pot.

[0004] However, while countertop range hoods are effective at removing smoke, some cooking fumes still escape, continuing to harm our health. Currently, the air inlet of most countertop range hoods is positioned at a 90° angle to the cooking countertop, resulting in a spatial separation between the negative pressure center generated by the hood and the source of the cooking fumes. Based on fluid dynamics analysis, this structure creates a 20-35cm gap between the negative pressure area and the natural upward path of the hot fumes, significantly exceeding the effective capture radius of the Brownian motion of the fume particles, thus failing to completely remove the fumes.

[0005] Therefore, a tabletop range hood is urgently needed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a tabletop range hood to solve the problem in related technologies where the negative pressure center generated by the tabletop range hood is spatially separated from the source of oil fumes, resulting in oil fume escape and inability to completely clean the oil fumes.

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] like Figures 1 to 8 As shown, this embodiment provides a tabletop range hood, which includes a main housing 1 and a smoke-collecting body 2. The main housing 1 is provided with a working chamber 111, and the side wall of the main housing 1 is provided with an installation port communicating with the working chamber 111. The smoke-collecting body 2 includes a smoke-collecting plate 21 and a smoke-collecting surround plate 22 arranged circumferentially around the smoke-collecting plate 21. The smoke-collecting plate 21 is provided with a smoke inlet, and the smoke-collecting surround plate 22 is inserted into the installation port. The bottom side of the smoke-collecting body 2 is pivotally connected to the main housing 1, so that the smoke-collecting body 2 swings relative to the main housing 1 within a preset included angle α. The smoke-collecting surround plate 22 can close the gap between the smoke-collecting plate 21 and the main housing 1. When using this tabletop range hood to suck up the fumes in a cooking pot, the tabletop range hood is placed next to the cooking pot, with the bottom side of the smoke-collecting body 2 close to the tabletop, creating a negative pressure zone at the smoke inlet of the smoke-collecting plate 21 to suck up the fumes in the cooking pot. When fumes escape from the cooking pot, the smoke-collecting body 2 swings outward relative to the main housing 1, thereby causing the smoke-collecting plate 21 to move closer to the source of fumes, shortening the distance between the negative pressure zone on the smoke-collecting plate 21 and the source of fumes, thus improving the escape of fumes from the cooking pot.

[0043] Optionally, the smoke collecting body 2 also includes a mesh plate 23, which is disposed on the smoke collecting plate 21 and covers the smoke inlet. The mesh plate 23 can evenly disperse the airflow, reduce the noise of the suction turbulence, and also intercept large oil droplets in the smoke.

[0044] Optionally, the maximum swing angle of the smoke-collecting body 2 relative to the main housing 1 is a preset angle α. Determining the preset angle α requires ensuring that the smoke-collecting baffle 22 always closes the gap between the smoke-collecting plate 21 and the main housing 1. The smoke-collecting baffle 22 always closes the gap between the smoke-collecting plate 21 and the main housing 1 to ensure sufficient negative pressure is generated at the smoke-collecting port of the smoke-collecting plate 21.

[0045] Optionally, the preset included angle α is 10° to 40°, preferably 35°.

[0046] Optionally, the tabletop range hood also includes a filter element 4 and a fan 5. The main housing 1 includes a body 11 and a middle frame 12. The working chamber 111 is located in the body 11, and the mounting port is located on the side wall of the body 11. The middle frame 12 is disposed in the working chamber 111 and divides the working chamber 111 into a front chamber 1111 and a rear chamber 1112. The mounting port communicates with the front chamber 1111. The middle frame 12 is provided with a through hole that communicates with the front chamber 1111 and the rear chamber 1112. The filter element 4 is disposed in the middle frame 12 and closes the through hole. The fan 5 is disposed in the rear chamber 1112. The air inlet of the fan 5 communicates with the through hole. The body 11 is also provided with an air outlet 114 that communicates with the rear chamber 1112. When the tabletop range hood is working, the fan 5 starts to work, which in turn creates a negative pressure zone outside the smoke collection plate 21, thereby drawing the oil fumes from the cooking pot into the working chamber 111. During this process, the oil fumes are filtered through the filter element 4, leaving the oil on the filter element 4. The gas enters the rear chamber 1112 and is finally discharged from the air outlet 114.

[0047] Optionally, the main housing 1 also includes a front plate 13, which is fixedly connected to the body 11 and closes the bottom area of ​​the mounting opening. The bottom side of the smoke collector 2 is pivotally connected to the top side of the front plate 13. In this embodiment, the front plate 13 is provided on the main housing 1, which can increase the pivot height between the smoke collector 2 and the main housing 1, thereby making the pivot height between the smoke collector 2 and the main housing 1 as close as possible to the height of the cooking pot. When the smoke collector 2 swings outward relative to the main housing 1, it can avoid the cooking pot from interfering with the smoke collector 2. At the same time, it can also make the smoke collector 2 closer to the smoke source of the cooking pot.

[0048] Optionally, the tabletop range hood also includes an oil cup 6, which is located inside the working chamber 111 and at the bottom of the filter element 4. The oil filtered by the filter element 4 can flow through the filter element 4 into the oil cup 6 and be collected.

[0049] Optionally, the tabletop range hood also includes a limiting member 3, which can fix the angle between the smoke gathering body 2 and the main housing 1. In this embodiment, this setting can adjust the angle between the smoke gathering body 2 and the main housing 1 according to different usage scenarios of the tabletop range hood.

[0050] Optionally, the limiting member 3 is elastic and fixed to the main housing 1; the smoke-collecting plate 22 is recessed with a slot 2211. When the smoke-collecting body 2 swings relative to the main housing 1, the limiting member 3 is inserted into the slot 2211 when it is aligned with the slot 2211. In this embodiment, during the swinging process of the smoke-collecting body 2 relative to the main housing 1, there is a position where the limiting member 3 is aligned with the slot 2211. At this time, the limiting member 3 is inserted into the slot 2211, thereby fixing the smoke-collecting body 2 relative to the main housing 1. When the user needs to adjust the angle of the smoke-collecting body 2 relative to the main housing 1 (e.g., when not using a tabletop smoke hood, the angle of the smoke-collecting body 2 relative to the main housing 1 needs to be adjusted to 0°), the user pushes the smoke-collecting body 2 to swing relative to the main housing 1, thereby causing the limiting member 3 to undergo elastic deformation, which allows the limiting member 3 to disengage from the slot 2211, and the smoke-collecting body 2 can then swing relative to the main housing 1.

[0051] Optionally, the limiting member 3 can be an elastic rubber or an elastic plate.

[0052] Optionally, multiple slots 2211 are provided, arranged sequentially and at intervals along the swing direction of the smoke collector 2. In this embodiment, during the swing of the smoke collector 2 relative to the main housing 1, the limiting member 3 will sequentially face the multiple slots 2211. When the force acting on the smoke collector 2 is removed, the limiting member 3 is inserted into the corresponding slot 2211, so that the smoke collector 2 is fixed relative to the main housing 1. This allows the smoke collector 2 to maintain multiple angles of relative fixation with respect to the main housing 1 within the included angle of 0° to a°, thereby realizing multi-level adjustment of the smoke collector 2 relative to the main housing 1.

[0053] Optionally, when the smoke collector 2 swings relative to the main housing 1 to a preset angle a°, the limiting member 3 engages with one of the multiple slots 2211. In this embodiment, when the smoke collector 2 swings relative to the main housing 1 at a preset angle a°, the limiting member 3 engages with one of the multiple slots 2211, thereby fixing the smoke collector 2 and the main housing 1 at the preset angle a°.

[0054] Optionally, when the angle between the smoke collector 2 and the main housing 1 is 0°, the limiting member 3 is inserted into another slot 2211 among the multiple slots 2211. In this embodiment, when the angle between the smoke collector 2 and the main housing 1 is 0°, the limiting member 3 is inserted into another slot 2211 among the multiple slots 2211, so as to fix the smoke collector 2 and the main housing 1 at a 0° angle.

[0055] Optionally, the main housing 1 and the smoke collector 2 are each provided with a clip 212 and a buckle 122, respectively. The angle between the smoke collector 2 and the main housing 1 is 0°, and the buckle 122 and the clip 212 are engaged. In this embodiment, when the angle between the smoke collector 2 and the main housing 1 is 0°, in addition to the limiting member 3 being inserted into the corresponding slot 2211, the buckle 122 is also engaged with the clip 212, thereby achieving redundant fixation.

[0056] Optionally, the buckle 122 is disposed on the middle frame 12, and the clip 212 is disposed on the smoke collection plate 21. Both the buckle 122 and the clip 212 are existing structures and will not be described in detail here.

[0057] Optionally, the limiting member 3 is located within the working cavity 111 and opposite to the smoke-collecting enclosure 22. The limiting member 3 includes a first elastic plate 31 and a second elastic plate 32. One end of the first elastic plate 31 and one end of the second elastic plate 32 are fixedly connected and form a V-shape. The V-shape can be inserted into the slot 2211. The other end of the first elastic plate 31 is fixedly connected to the main housing 1, and the other end of the second elastic plate 32 abuts against the main housing 1. In this embodiment, the portion of the limiting member 3 inserted into the slot 2211 is configured as a V-shape, which facilitates the limiting member 3's disengagement from the slot 2211 and prevents the limiting member 3 from getting stuck in the slot 2211. The other end of the first elastic plate 31 is fixedly connected to the main housing 1, which allows the limiting member 3 to be fixed to the body 11. The other end of the second elastic plate 32 abuts against the body 11, which allows the limiting member 3 to undergo a certain amount of elastic deformation.

[0058] Optionally, the cross-section of the slot 2211 is trapezoidal along the swing direction of the smoke collector 2. This design also prevents the limiting member 3 from getting stuck in the slot 2211.

[0059] Optionally, the limiting component 3 is a one-piece molded component.

[0060] Optionally, the middle frame 12 includes an upper side plate 121, which has a limiting hole 1211. A limiting member 3 is inserted into the limiting hole 1211. A first elastic plate 31 abuts against the inner wall of the limiting hole 1211, and a second elastic plate 32 abuts against the inner wall of the limiting hole 1211. In this embodiment, the first elastic plate 31 and the second elastic plate 32 correspond one-to-one with the two opposite inner walls of the limiting hole 1211. This arrangement allows the upper side plate 121 to constrain the limiting member 3, which can increase the force required for the limiting member 3 to disengage from the slot 2211 and improve the stability of the smoke collector 2 relative to the main housing 1.

[0061] Optionally, the smoke-collecting enclosure 22 includes a top enclosure 221 and two side enclosures 222. One side enclosure 222 is fixedly connected to one end of the top enclosure 221, and the other side enclosure 222 is fixedly connected to the other end of the top enclosure 221. The upper side plate 121 is opposite to the top enclosure 221, and both the upper side plate 121 and the top enclosure 221 are arc-shaped plates with the pivot axis between the smoke-collecting body 2 and the main housing 1 as the center. In this embodiment, when the smoke-collecting enclosure 21 swings relative to the main housing 1, gaps will be generated between the top and sides of the smoke-collecting enclosure 21 and the main housing 1. In order to prevent the leakage of oil fumes, the top enclosure 221 and the two side enclosures 222 are needed to seal the gaps generated between the smoke-collecting enclosure 21 and the main housing 1. Both the upper side plate 121 and the top enclosure plate 221 are arc-shaped plates with the pivot axis between the smoke collector 2 and the main housing 1 as the center. When the smoke collector 21 swings relative to the main housing 1, this arrangement can prevent motion interference between the upper side plate 121 and the top enclosure plate 221.

[0062] Optionally, a guide plate 24 is also provided on the smoke collection plate 21. The guide plate 24 is located below the mesh plate 23. The guide plate 24 extends into the oil cup 6 and can direct the oil intercepted by the mesh plate 23 into the oil cup 6.

[0063] Optionally, the smoke-collecting panel 22 has an outwardly flanged edge 223 on the side away from the smoke-collecting plate 21, and a protrusion 1212 fixed relative to the main housing 1 is provided in the working cavity 111. The protrusion 1212 is located between the outwardly flanged edge 223 and the smoke-collecting plate 21. The smoke-collecting body 2 swings relative to the main housing 1 at a preset angle α, and the protrusion 1212 abuts against the outwardly flanged edge 223. In this embodiment, when the smoke-collecting body 2 swings relative to the main housing 1 at a preset angle α, the insertion of the limiting member 3 into the slot 2211, and the above-mentioned arrangement, form a redundancy in fixing the smoke-collecting body 2 relative to the main housing 1.

[0064] Optionally, the main body 11 is recessed with an L-shaped relief groove 113, which is opposite to the smoke gathering plate 21 to avoid the hand-clip position of the smoke gathering plate 21.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
