Range hoods and their components

Abstract

The present invention discloses a range hood and its assembly. The range hood assembly includes a smoke collecting hood, a panel, and a driving mechanism. The smoke collecting hood is used to define a smoke collecting chamber having an opening area. The panel is covered on the opening area. The panel has a front edge and a rear edge arranged opposite to each other, wherein the front edge is closer to the user side than the rear edge. The panel is provided with a first smoke inlet at a position close to the rear edge, and a second smoke inlet is formed between the front edge and the smoke collecting hood. The driving mechanism is used to drive the panel to adjust its position relative to the smoke collecting hood, thereby adjusting the width of the second smoke inlet while adjusting the height of the first smoke inlet. In this way, not only can the distance between the first smoke inlet and the stove be shortened, facilitating the timely discharge of oil smoke through the first smoke inlet, but the width of the second smoke inlet can also be increased. Oil smoke that diffuses to the user side can be discharged through the second smoke inlet with a larger width, thereby improving the smoke exhaust effect of the range hood.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The terms "first", "second" and "third" in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first", "second" and "third" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1 , Figure 1This is a schematic diagram of the planar structure of a European-style range hood in related art. This European-style range hood 100 is typically located above the cooktop, at a distance from the cooktop. It primarily comprises a smoke-collecting section 110, a frame section 120, and a fan 130. The fan 130 is mounted within the frame section 120, which is secured to its underside. The fan 130 operates by suctioning and exhausting air, creating a negative pressure zone through the smoke-collecting section 110, which draws away cooking fumes.

[0030] Because the European-style range hood 100 is far from the stove, cooking fumes cannot be drawn away promptly, easily causing them to diffuse, resulting in poor extraction efficiency. Furthermore, the deflector 112 of the European-style range hood 100 typically has a large front-to-back dimension D, making it easy for the user's head to bump against the deflector 112 during cooking, thus negatively impacting the user experience. If the front-to-back dimension D of the deflector 112 is reduced, cooking fumes will easily diffuse from the front, further reducing extraction efficiency.

[0031] In order to improve the smoking effect and enhance the user experience, the near-smoking machine 200 has been gradually developed. Figure 2 , Figure 2 This is a schematic diagram of the planar structure of a smoke extractor in related art. The smoke extractor 200 is located above the cooktop and comprises a smoke collection section 210, a frame section 220, and a fan 230. The smoke collection section 210 extends near the cooktop. The fan 230 of the smoke extractor 200 is housed within the smoke collection section 210 and provides both air intake and exhaust. Some smoke extractors 200 also feature an opening and closing plate 240, which helps collect smoke and improves the smoke extraction effect.

[0032] Due to the small front-to-back dimensions of the smoke extractor 200, oil smoke easily spreads forward, resulting in poor smoke extraction. Furthermore, the wok can easily collide with the smoke extractor 200 when cooking, further reducing the user experience. Furthermore, the fan 230 of the smoke extractor 200 is tilted, creating an elbow at its outlet, increasing smoke exhaust resistance and reducing smoke extraction efficiency.

[0033] In order to improve the smoking effect of the range hood, the present invention provides a range hood 300, please refer to Figure 3 and Figure 4 , Figure 3 1 is a schematic diagram of the three-dimensional structure of a range hood in one embodiment of the present invention. Figure 4 yes Figure 3The cross-sectional structural diagram of the range hood in FIG. The range hood 300 includes a frame 310 and a range hood assembly 320. The range hood assembly 320 includes a smoke collecting hood 321, a panel 322, and a driving mechanism 323. The smoke collecting hood 321 is used to define a smoke collecting chamber 3212 having an opening area; the panel 322 is covered on the opening area, and the panel 322 has a front edge 3221 and a rear edge 3223 arranged opposite to each other, wherein the front edge 3221 is closer to the user side than the rear edge 3223, and the panel 322 is provided with a first smoke inlet 3225 at a position close to the rear edge 3223, and a second smoke inlet 3227 is formed between the front edge 3221 and the smoke collecting hood 321; the driving mechanism 323 is used to drive the panel 322 to adjust its position relative to the smoke collecting hood 321, thereby adjusting the width of the second smoke inlet 3227 while adjusting the height of the first smoke inlet 3225.

[0034] Specifically, the smoke hood 321 and the panel 322 enclose a smoke collecting chamber 3212. The frame 310 is connected to the side of the smoke hood 321 facing away from the smoke collecting chamber 3212, and the interior of the frame 310 is in communication with the smoke collecting chamber 3212. A fan 330 can be disposed within the frame 310. Oil smoke that enters the smoke collecting chamber 3212 through the first smoke inlet 3225 and the second smoke inlet 3227 is exhausted by the fan 330 disposed within the frame 310.

[0035] Typically, the range hood 300 is mounted on a wall. The front edge 3221 of the panel 322 is the side of the panel 322 closest to the user, while the rear edge 3223 of the panel 322 is the side of the panel 322 closest to the wall. A first smoke inlet 3225 is provided on the side of the panel 322 closest to the wall to absorb cooking fumes from the wall. The gap between the front edge 3221 of the panel 322 and the smoke collecting hood 321 forms a second smoke inlet 3227 to absorb cooking fumes that diffuse toward the front of the range hood 300. In this way, cooking fumes from above the stove can be drawn in through the first and second smoke inlets 3225 and 3227, respectively, enhancing the smoke extraction efficiency of the range hood 300.

[0036] like Figure 5 and Figure 6 As shown, Figure 5 1 is a schematic diagram of the three-dimensional structure of a range hood in one embodiment of the present invention. Figure 6 yes Figure 5A cross-sectional view of the range hood is shown in Figure 3. When cooking generates a large amount of fumes, the drive mechanism 323 drives the panel 322 relative to the fume collecting hood 321, causing the rear edge 3223 of the panel 322 to move toward the stove, i.e., downward in the direction of the arrow in the figure. This shortens the distance between the first fume inlet 3225 and the stove, facilitating the timely exhaust of fumes through the first fume inlet 3225. Furthermore, as the rear edge 3223 of the panel 322 moves toward the stove, the front edge 3221 of the panel 322 moves toward the wall, increasing the gap between the front edge 3221 of the panel 322 and the fume collecting hood 321. This increases the width of the second fume inlet 3227. Fumes that have spread to the user's side can then be exhausted through the wider second fume inlet 3227, further enhancing the exhaust efficiency of the range hood 300. When the cooking fume is small, the driving mechanism 323 drives the panel 322 to move relative to the fume collecting hood 321, so that the rear edge 3223 of the panel 322 moves away from the stove, that is, moves upward in the direction of the arrow in the figure. Figure 3 and Figure 7 As shown, Figure 7 yes Figure 3 The panel 322 is accommodated in the smoke collecting chamber 3212, and the distance between the first smoke inlet 3225 and the stove is increased to avoid collision between the panel 322 and the cooking utensils, thereby improving the user experience.

[0037] like Figure 3 and Figure 4 As shown, the smoke collecting hood 321 includes a top panel 3211, a back panel 3213, and two first side panels 3215. The top panel 3211 and the back panel 3213 are arranged at an angle. For example, the top panel 3211 and the back panel 3213 can be arranged at a right angle, or the top panel 3211 and the back panel 3213 can be arranged at an obtuse angle to shorten the distance between the range hood 300 and the wall to prevent collisions with users. The two first side panels 3215 are connected between the top panel 3211 and the back panel 3213 and are spaced apart from each other to form a smoke collecting chamber 3212 between the two first side panels 3215.

[0038] Specifically, in this embodiment, the top panel 3211 is rectangular, and the back panel 3213 is connected to one side of the top panel 3211 adjacent to the wall to prevent cooking fumes from adhering to the wall. Two first side panels 3215 are provided on opposite sides of the top panel 3211 and connected between the top panel 3211 and the back panel 3213 to collect cooking fumes and prevent them from spreading.

[0039] It is understandable that when the top plate 3211 is set to other shapes, the number of the first side plates 3215 can also be flexibly set according to needs, and the embodiment of the present application does not make specific limitations.

[0040] Furthermore, if Figure 5 and Figure 8 As shown, Figure 8 This is an exploded cross-sectional view of a range hood according to an embodiment of the present invention. The panel 322 comprises a panel body 3222 and two second side panels 3224. The two second side panels 3224 are bent and connected to the panel body 3222 and spaced apart from each other on one side of the corresponding first side panel 3215. The first smoke inlet 3225 is disposed on the panel body 3222 and is located in the space between the two second side panels 3224.

[0041] Specifically, the panel body 3222 is used to cover the opening of the smoke collecting chamber 3212. The first smoke inlet 3225 is provided on the panel body 3222 and is located on the side of the panel body 3222 close to the wall. The two second side panels 3224 are respectively spaced apart from the corresponding first side panels 3215.

[0042] When the driving mechanism 323 drives the panel 322 to move toward the stove, the distance between the panel body 3222 and the smoke collecting hood 321 gradually increases. When the panel body 3222 protrudes from the first side panel 3215, a gap will exist between the panel body 3222 and the first side panel 3215. The existence of the gap will cause the oil smoke entering the smoke collecting chamber 3212 from the first smoke inlet 3225 and the second smoke inlet 3227 to leak, causing smoke to leak from the side of the range hood 300, reducing the smoking effect; moreover, the existence of the gap will also destroy the sealing of the smoke collecting chamber 3212, reduce the negative pressure generated by the fan 330 in the smoke collecting chamber 3212, and make it inconvenient for the oil smoke to be discharged from the range hood 300.

[0043] Therefore, in this embodiment, the two second side panels 3224 can be configured to at least partially overlap the corresponding first side panels 3215 during the process of the driving mechanism 323 adjusting the position of the panel 322. Specifically, it is necessary to ensure that when the panel body 3222 moves to its furthest position relative to the smoke collecting hood 321, the two second side panels 3224 at least partially overlap the corresponding first side panels 3215. This ensures that the panel 322 always seals the smoke collecting chamber 3212 during its movement. This prevents oil smoke from leaking from the sides of the range hood 300, improving the smoke extraction efficiency, and also increases the negative pressure generated by the fan 330, improving the smoke exhaust efficiency.

[0044] If the driving mechanism 323 is directly connected to the panel 322 , the panel 322 may be easily skewed when the driving mechanism 323 drives the panel 322 to move, thereby reducing the sealing performance of the smoke collecting chamber 3212 .

[0045] Therefore, in this embodiment, if Figure 6As shown, a first sliding stopper mechanism 326 and a second sliding stopper mechanism 327 can be provided on the smoke collecting hood 321. The first sliding stopper mechanism 326 has a projection component in the vertical direction and is used to slide and stop the rear edge 3223 of the panel 322, so that the rear edge 3223 of the panel 322 can move at least in the vertical direction when sliding along the first sliding stopper mechanism 326, thereby moving closer to or farther away from the cooktop, thereby adjusting the distance between the first smoke inlet 3225 located at the rear edge 3223 and the cooktop. The second sliding stopper mechanism 327 has a projection component in the horizontal direction and is used to slide and stop the front edge 3221 of the panel 322, so that the front edge 3221 of the panel 322 can move at least in the horizontal direction when sliding along the second sliding stopper mechanism 327, thereby increasing or decreasing the distance between the front edge 3221 of the panel 322 and the smoke collecting hood 321, thereby expanding or decreasing the width of the second smoke inlet 3227. By setting up a driving mechanism 323 to drive the panel 322 to slide along the first sliding limit mechanism 326 and the second sliding limit mechanism 327, the smoothness of the movement of the panel 322 can be improved, and the movement consistency of the front edge 3221 and the rear edge 3223 of the panel 322 can be made higher, thereby improving the stability of the adjustment of the panel 322.

[0046] Optionally, a first sliding stopper mechanism 326 may be provided on the back plate 3213, and the panel body 3222 may be slidably provided on the first sliding stopper mechanism 326, so as to slidably connect the panel body 3222 to the back plate 3213. When the driving mechanism 323 drives the panel 322 to move and extend out of the smoke collecting chamber 3212, the gap between the panel body 3222 and the back plate 3213 may destroy the sealing of the smoke collecting chamber 3212, causing the oil smoke in the smoke collecting chamber 3212 to leak from the side where the back plate 3213 is located, thereby contaminating the wall surface, and also reducing the negative pressure generated by the fan 330, making it difficult to discharge the oil smoke.

[0047] Therefore, in this embodiment, the range hood assembly 320 can be set to also include a sliding plate 324, which is slidably supported on the first sliding limit mechanism 326, and the driving mechanism 323 is connected to the sliding plate 324, and drives the sliding plate 324 to slide along the first sliding limit mechanism 326, and the rear edge 3223 of the panel 322 or a position close to the rear edge 3223 is rotatably connected to the sliding plate 324.

[0048] In this way, by setting a sliding plate 324 connecting the panel 322 and the back plate 3213, on the one hand, the sliding plate 324 is slidably connected to the back plate 3213, which can drive the panel 322 to move closer to or away from the stove; on the other hand, the sliding plate 324 can also seal the gap between the panel body 3222 and the back plate 3213, thereby improving the sealing of the smoke collection chamber 3212, avoiding the leakage of oil smoke and improving the smoke exhaust effect.

[0049] Among them, the rear edge 3223 of the panel 322 can be hinged to the back panel 3213 through a rotating shaft or hinge, or the position of the panel 322 close to the rear edge 3223 can be hinged to the back panel 3213 through a rotating shaft or hinge. The embodiment of the present invention does not limit the rotational connection method of the panel 322 and the sliding plate 324.

[0050] Furthermore, when the sliding plate 324 slides downward along the first sliding stop mechanism 326, the sliding plate 324 extends beyond the lower edge of the back plate 3213. This not only increases the downward movement distance of the panel 322, but also shortens the vertical length of the back plate 3213. Consequently, when the panel 322 is housed within the smoke collecting hood 321, the vertical dimension of the range hood 300 can be shortened, thereby reducing the volume of the range hood 300.

[0051] As the driving mechanism 323 drives the sliding plate 324 to move toward the stove, the distance between the sliding plate 324 and the back plate 3213 gradually increases. When the sliding plate 324 protrudes from the back plate 3213, a gap will exist between the sliding plate 324 and the back plate 3213. The existence of the gap will cause the oil smoke entering the smoke gathering chamber 3212 from the first smoke inlet 3225 and the second smoke inlet 3227 to leak, causing smoke to leak from the back of the range hood 300, reducing the smoking effect; moreover, the existence of the gap will also destroy the sealing of the smoke gathering chamber 3212, reduce the negative pressure generated by the fan 330 in the smoke gathering chamber 3212, and make it inconvenient for the oil smoke to be discharged from the range hood 300.

[0052] Therefore, the sliding plate 324 can be arranged to maintain at least partial overlap with the back plate 3213 during the sliding process along the first sliding limit mechanism 326. In this way, when the sliding plate 324 moves to the position with the maximum distance relative to the smoke collecting hood 321, there is no gap between the back plate 3213 and the sliding plate 324, so that the smoke collecting chamber 3212 can be sealed, thereby preventing oil smoke from leaking from the back of the range hood 300 and improving the smoke exhaust effect.

[0053] Furthermore, when oil smoke encounters the panel body 3222, it condenses into oil smoke droplets, which adhere to the panel body 3222. Since the panel body 3222 in this embodiment of the present invention is tilted, the oil smoke droplets adhering to the panel body 3222 will move toward the position near the rear edge 3223 under the action of gravity. When a large number of oil smoke droplets accumulate on the rear edge 3223, they will break away from the panel body 3222 and drip onto the cooktop. Not only are these oil smoke droplets difficult to clean, but they may also drip into the cookware and contaminate the food.

[0054] Therefore, if Figure 6 and Figure 9 As shown, Figure 9 yes Figure 6 The hood assembly 320 also includes an oil cup 325, which is connected to the sliding plate 324. The vertical projection of the rear edge 3223 of the panel 322 falls into the opening of the oil cup 325. This way, when oil fume droplets begin to drip, the oil cup 325, with its opening positioned below the droplets, collects them. This prevents the droplets from dripping onto the cooktop or onto food, thereby improving the user experience and enhancing food safety.

[0055] In order to avoid interference between the panel 322 and the oil cup 325 during the movement relative to the smoke hood 321, the gap between the side wall of the opening of the oil cup 325 and the panel body 3222 can be set to be at least larger than the maximum rotation angle of the panel body 3222 relative to the sliding plate 324, so as to ensure that when the panel body 3222 is rotated to the maximum angle position relative to the sliding plate 324, there is still a gap between the panel body 3222 and the side wall of the opening of the oil cup 325 for accommodating oil smoke droplets.

[0056] In order to facilitate the connection of the oil cup 325 to the sliding plate 324, as shown in FIG. Figure 6 and Figure 8 As shown, the sliding plate 324 can include a first plate 3241 and a second plate 3243 connected in an L-shape. The first plate 3241 can be slidably supported on a first sliding stopper 326 for sliding connection with the back plate 3213. The second plate 3243 extends away from the smoke collecting chamber 3212, and the oil cup 325 is connected to the second plate 3243. By providing the first and second plates 3241, 3243 in a curved connection, the connection area between the oil cup 325 and the sliding plate 324 can be increased, thereby improving the connection stability of the oil cup 325.

[0057] Furthermore, the first plate 3241 can be positioned on the side of the back plate 3213 facing the smoke collecting chamber 3212, the second plate 3243 can be connected to the end of the first plate 3241 and extended toward the side facing away from the smoke collecting chamber 3212, and the drive mechanism 323 can be connected to the second plate 3243. In this manner, the drive mechanism 323 can drive the second plate 3243, thereby driving the entire sliding plate 324 to move. Due to the larger area of ​​the second plate 3243, the connection between the sliding plate 324 and the drive mechanism 323 can be facilitated. Furthermore, positioning the drive mechanism 323 on the side of the first plate 3241 facing away from the smoke collecting chamber 3212 can also prevent the drive mechanism 323 from coming into contact with oil smoke and causing damage.

[0058] Alternatively, as Figure 6 and Figure 8 As shown, the first sliding limiting mechanism 326 includes a sliding rail 3261 and a slider 3262 that are slidably matched. The sliding rail 3261 is set on the back plate 3213, and the slider 3262 is set on the sliding plate 324.

[0059] Furthermore, the slide rail 3261 may be arranged in a vertical direction, and the slider 3262 is connected to a side of the sliding plate 324 facing the back plate 3213 to be slidably connected to the slide rail 3261 .

[0060] It is understandable that the slide rail 3261 may be disposed on the sliding plate 324 and the slider 3262 may be disposed on the back plate 3213 so as to slidably connect the sliding plate 324 and the back plate 3213 .

[0061] Furthermore, if Figure 6 、 Figure 8 and Figure 10 As shown, Figure 10 The figure is a schematic cross-sectional view of the second sliding limit mechanism. The second sliding limit mechanism 327 includes a guide groove 3271 and a guide post 3272 that slide together. The guide groove 3271 is provided on the first side panel 3215, and the guide post 3272 is provided on the panel 322. The guide post 3272 is inserted into the guide groove 3271. Specifically, the guide groove 3271 can be provided on the side of the first side panel 3215 facing the smoke collecting chamber 3212. The guide groove 3271 has a projected component in the horizontal direction. The guide post 3272 can be fixed to the second side panel 3224 of the panel 322 via fasteners and inserted into the guide groove 3271. In this way, the guide post 3272 can slide within the guide groove 3271 to guide the front edge 3221 of the panel 322 via the guide groove 3271.

[0062] It is understandable that the guide groove 3271 can also be set on the second side plate 3224, and the guide column 3272 can be set on the first side plate 3215 to slidingly connect the panel 322 and the first side plate 3215.

[0063] Alternatively, in some other embodiments, other types of first sliding limiting mechanisms 326 and second sliding limiting mechanisms 327 may be provided to slidingly connect the panel 322 and the smoke collecting hood 321 , which is not specifically limited in the embodiment of the present application.

[0064] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
