Technical Field

[0001] The present invention relates to the field of range hoods, and in particular to a drainage component and a range hood having the same. Background Art

[0002] At present, some range hoods are equipped with drainage plates to guide the oil smoke into the air inlet of the range hood. At the same time, the drainage plate can also isolate the internal structure of the range hood from the external space to prevent users from accidentally touching the internal structure, thereby improving the safety factor.

[0003] However, the drainage plate on the existing range hood is generally a whole plate extending from the left side to the right side of the smoke hood. When this drainage plate is draining, the oil smoke in the middle area below the drainage plate often has poor circulation, causing oil pressure accumulation in the area, resulting in a large amount of oil smoke escaping and poor oil smoke absorption effect.

[0004] In summary, how to overcome the above-mentioned defects of the guide plates on the existing range hoods is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide a drainage assembly and a range hood having the same, so as to alleviate the technical problem that the guide plate on the range hood in the prior art easily causes poor oil smoke circulation in the middle area below the range hood.

[0006] The guide assembly provided by the present invention is arranged at the air inlet of the range hood, and includes at least two first guide members, a first gap exists between the at least two first guide members, and a second gap exists between the first guide member and the smoke collecting hood. The first guide member can block the oil smoke and can guide the blocked oil smoke to the first gap and the second gap respectively.

[0007] Preferably, as an implementable embodiment, the drainage assembly further includes a second drainage member, at least two of the first drainage members are respectively connected to the side surfaces of the second drainage member, and the first gap exists between the second drainage member and each of the first drainage members.

[0008] Preferably, as an implementable embodiment, condensate formed on the first guide piece by the oil and water vapor in the oil smoke can flow along the first guide piece to the second guide piece, and the condensate formed on the second guide piece and the condensate flowing from the first guide piece to the second guide piece can both flow along the second guide piece to the oil collecting cup corresponding to the second guide piece.

[0009] Preferably, as an implementable embodiment, the first flow guide member is inclined downward from a side away from the second flow guide member to a side close to the second flow guide member, and the lower end of the first flow guide member partially overlaps with the projection area of ​​the second flow guide member on the horizontal plane;

[0010] And / or, the second flow guide member is inclined downward from an end away from the oil receiving cup to an end close to the oil receiving cup, and the lower end of the second flow guide member partially overlaps with the projection area of ​​the oil receiving cup on the horizontal plane.

[0011] Preferably, as an implementable embodiment, the bottom surface of the first flow guiding member has a plurality of first flow guiding grooves, and the first flow guiding grooves extend from a side of the first flow guiding member close to the second flow guiding member to a side of the first flow guiding member away from the second flow guiding member;

[0012] And / or, the upper surface of the first flow guiding member has a plurality of second flow guiding grooves, and the second flow guiding grooves extend from a side of the first flow guiding member close to the second flow guiding member to a side of the first flow guiding member away from the second flow guiding member.

[0013] Preferably, as an implementable embodiment, the cross-sectional area of ​​the first drainage groove gradually decreases from an end away from the second drainage member to an end close to the second drainage member;

[0014] And / or, the cross-sectional area of ​​the second drainage groove gradually decreases from an end away from the second drainage member to an end close to the second drainage member.

[0015] Preferably, as an implementable embodiment, a side of the bottom surface of the first flow guiding member facing away from the second flow guiding member is a curved surface that gradually bends upward.

[0016] Preferably, as an implementable embodiment, the second flow guiding member is a groove body having two left and right groove walls, and a guide port is provided at one end of the second flow guiding member close to the oil receiving cup.

[0017] Preferably, as an implementable embodiment, each of the first flow guiding members is connected to the second flow guiding member.

[0018] Each of the first flow guide members is detachably connected to the smoke collecting hood via a snap-on assembly, or each of the first flow guide members is connected to the smoke collecting hood via a telescopic motor or a telescopic cylinder.

A first gap is set between at least two first flow guides, and a second gap is set between the first flow guide and the smoke collecting hood, so that when the range hood is working, a negative pressure environment is formed in the first gap and the second gap. Under the action of the negative pressure environment and the Coanda effect, part of the oil smoke generated during cooking can directly pass through the first gap or the second gap to enter the air inlet of the range hood, and part of the oil smoke will be blocked by the first flow guide. This part of the oil smoke blocked by the first flow guide can be divided into two parts and flow along the first flow guide to the first gap and the second gap respectively, and finally, pass through the first gap or the second gap to enter the air inlet of the range hood. That is to say, the oil smoke can not only enter the air inlet of the range hood from the second gap at the edge position, but also enter the air inlet of the range hood from the first gap at the middle position. In this way, the problem of poor oil smoke circulation and easy accumulation of oil smoke in the middle area below the range hood can be well alleviated, thereby reducing the amount of oil smoke escape and improving the oil smoke absorption effect.

[0038] The technical solution of the present invention will be described clearly and completely below 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 creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0042] See also Figures 1 to 7The present embodiment provides a drainage assembly 100, which is arranged at the air inlet of the range hood. The drainage assembly 100 includes at least two first drainage members 120. There is a first gap between the at least two first drainage members 120. There is a second gap between the first drainage member 120 and the smoke collecting hood 200. The first drainage member 120 can block the oil smoke and can respectively drain the blocked oil smoke to the first gap and the second gap.

[0043] It should be noted that, by setting the drainage component 100 at the air inlet of the range hood, the drainage component 100 can isolate the internal structure of the range hood from the external space, prevent the user from accidentally touching the internal structure, and improve the safety factor. A first gap is set between at least two first flow guides 120, and a second gap is set between the first flow guide 120 and the smoke hood 200, so that when the range hood is working, a negative pressure environment is formed in the first gap and the second gap. Under the action of the negative pressure environment and the Coanda effect, part of the oil smoke generated during cooking can directly pass through the first gap or the second gap to enter the air inlet of the range hood, and part of the oil smoke will be blocked by the first flow guide 120. This part of the oil smoke blocked by the first flow guide 120 can be divided into two parts and flow along the first flow guide 120 to the first gap and the second gap respectively, and finally, pass through the first gap or the second gap to enter the air inlet of the range hood. That is to say, the oil smoke can not only enter the air inlet of the range hood from the second gap at the edge position, but also enter the air inlet of the range hood from the first gap at the middle position. In this way, the problem of poor oil smoke circulation and easy accumulation of oil smoke in the middle area below the range hood can be well alleviated, thereby reducing the amount of oil smoke escape and improving the oil smoke absorption effect.

[0044] It can be understood that the existence of the first gap between at least two of the first flow guides 120 means that the first gap can be formed between two first flow guides 120, or between three first flow guides 120, or between four first flow guides 120. As the number of first flow guides 120 increases, they can all be combined to form a first gap, so that oil smoke can enter the air inlet through the first gap, thereby improving the oil smoke absorption effect. For example, when there are two first flow guides 120, the connection between the two first flow guides 120 forms the first gap; when there are three first flow guides 120, the connection between the three first flow guides 120 forms the first gap, and the three first flow guides 120 can be combined to form the first gap.

[0045] In the specific structure of the drainage component 100 , a second drainage member 110 may be further provided, so that at least two first drainage members 120 are respectively connected to the sides of the second drainage member 110 , and the first gap is reserved between the second drainage member 110 and each first drainage member 120 .

[0046] Preferably, at least two first guide members 120 can be respectively connected to the opposite sides of the second guide member 110, which means that when there are two first guide members 120, the two first guide members 120 are connected to the opposite sides of the second guide member 110; when there are three or more first guide members 120, two of the first guide members 120 are connected to the opposite sides of the second guide member 110, and the other first guide members 120 can be symmetrically arranged on the opposite sides of the second guide member 110, or on the same side or on asymmetrical sides, which can be selected according to actual needs.

[0047] In particular, two first guide members 120 can be provided, and the two first guide members 120 can be symmetrically arranged relative to the second guide member 110, thereby shortening the flow distance required for the oil smoke to reach the first gap, and allowing the oil smoke generated in the two pots under the range hood to be better drained.

[0048] The left and right sides of the second guide member 110 can be connected to the two first guide members 120 respectively, so that the second guide member 110 and the first guide member 120 can form an integral structure. On this basis, the two first guide members 120 are connected to the smoke hood 200, so that the positioning of the guide assembly 100 can be achieved.

[0049] Specifically, the first flow guiding member 120 and the second flow guiding member 110 can be processed from a whole plate, and the first gap between the first flow guiding member 120 and the second flow guiding member 110 can be formed by a drop.

[0050] The two first flow guiding members 120 may be arranged to form an angle of 10 degrees with the horizontal plane.

[0051] The number of first guide members 120 may be multiple, and three are used as an example for specific description below: on the basis of setting two first guide members 120, an additional first guide member 120 may be provided on the front side or the rear side of the second guide member 110. In this structure, the first gap between the newly added first guide member 120 and the second guide member 110 may also be formed by a drop. An additional first guide member 120 may also be provided on the side of the first guide member 120 away from the second guide member 110. In this structure, the first gap between the newly added first guide member 120 and the adjacent first guide member 120 may also be formed by a drop.

[0052] During the operation of the range hood, the oil smoke containing grease and water vapor will flow from bottom to top toward the drainage component 100 blocking the air inlet of the range hood under the suction of the range hood. When the oil smoke contacts the first drainage piece 120, part of the grease and water vapor in the oil smoke will condense into condensate, which will flow along the first drainage piece 120 to the second drainage piece 110, and then will flow into the oil receiving cup 300 of the range hood along the second drainage piece 110; when the oil smoke contacts the second drainage piece 110, part of the grease and water vapor in the oil smoke will also condense into condensate, which will also flow along the second drainage piece 110 into the oil receiving cup 300 of the range hood, thereby realizing the function of oil smoke separation.

[0053] The first guide member 120 is rotatably connected to the second guide member 110. The size of the first gap can be adjusted by the rotatable connection between the first guide member 120 and the second guide member 110, and the size of the first gap can be adjusted according to actual needs to improve the smoking efficiency and applicability of the guide assembly.

[0054] Specifically, the first guide member 120 is arranged to be inclined downward (relative to the user's position during actual use, not referring to the absolute position) from the side away from the second guide member 110 to the side close to the second guide member 110, and the lower end of the first guide member 120 close to the second guide member 110 partially overlaps with the projection area of ​​the second guide member 110 on the horizontal plane, so that the condensate on the first guide member 120 can flow along the first guide member 120 to the second guide member 110 under the action of its own gravity, and drip onto the second guide member 110.

[0055] Specifically, the lower end of the first flow guide member 120 can be extended to directly above the second flow guide member 110, so that the portion of the lower end of the first flow guide member 120 directly above the second flow guide member 110 can overlap with the projection area of ​​the second flow guide member 110 on the horizontal plane.

[0056] See also Figure 7, a plurality of first drainage grooves 121 can be provided on the bottom surface of the first drainage member 120, and the first drainage grooves 121 are provided to extend from the side of the first drainage member 120 close to the second drainage member 110 to the side of the first drainage member 120 away from the second drainage member 110. On the one hand, when the area occupied by the first drainage member 120 remains unchanged, the contact area between the lower surface of the first drainage member 120 and the oil smoke can be increased, so as to facilitate the Coanda effect to play a better role, improve the drainage effect, and reduce the escape of oil smoke; on the other hand, the first drainage grooves 121 can also hold the oil smoke, which can not only reduce the oil smoke escaping from the front and rear sides of the first drainage member 120, but also relieve the discomfort caused by the user looking directly at the oil smoke; in addition, the first drainage grooves 121 can also better drain the condensate on the lower surface of the first drainage member 120, so that the condensate can flow more smoothly to the second drainage member 110.

[0057] The cross-sectional area of ​​the first drainage groove 121 can be set to gradually decrease from the end away from the second drainage member 110 to the end close to the second drainage member 110, that is, when there are multiple first drainage grooves 121, the multiple first drainage grooves 121 can be combined to form a fan-shaped structure, thereby not only increasing the flow rate of oil smoke in the first drainage groove 121, improving the oil smoke absorption effect of the range hood, and reducing oil smoke escape; but also enabling the condensate to gradually converge during the flow process, so that the condensate can drip onto the second drainage member 110 more smoothly.

[0058] It should be noted that the number of the first drainage groove 121 on the first drainage member 120 can be one or more.

[0059] See also Figure 3 and Figure 4 A plurality of second drainage grooves 122 may be provided on the upper surface of the first drainage member 120, and the second drainage grooves 122 may be provided to extend from a side of the first drainage member 120 close to the second drainage member 110 to a side of the first drainage member 120 away from the second drainage member 110. The second drainage grooves 122 may better drain the condensate, so that the condensate on the upper surface of the first drainage member 120 may flow more smoothly to the second drainage member 110.

[0060] The cross-sectional area of ​​the second drainage groove 122 can be set to gradually decrease from one end away from the second drainage member 110 to the end close to the second drainage member 110, that is, when there are multiple second drainage grooves 122, the multiple second drainage grooves 122 can be combined to form a fan-shaped structure, thereby not only increasing the flow rate of oil smoke in the second drainage groove 122, improving the oil smoke absorption effect of the range hood, and reducing oil smoke escape; but also enabling the condensate to gradually converge during the flow process, so that the condensate can drip onto the second drainage member 110 more smoothly.

[0061] It should be noted that the number of the second drainage groove 122 on the first drainage member 120 can be one or more.

[0062] In particular, the first flow guiding member 120 may be configured as a corrugated plate, thereby reducing the material usage and further reducing the cost of the first flow guiding member 120 .

[0063] See also Figure 5 and Figure 6 The side of the bottom surface of the first guide member 120 facing away from the second guide member 110 can be set to a curved surface that gradually bends upward, that is, the side of the second gap formed between the first guide member 120 and the smoke collecting hood 200 gradually bends upward to form a curved surface, thereby alleviating the problem of interference between the airflow guided to the second gap by the first guide member 120 and the airflow flowing vertically upward from the bottom to the second gap, thereby improving the fume absorption effect.

[0064] See also Figure 1 and Figure 5 The second guide member 110 can be tilted downward from the end away from the oil receiving cup 300 to the end close to the oil receiving cup 300 (relative to the user's position during actual use, not referring to the absolute position), and the lower end of the second guide member 110 is made to partially overlap with the projection area of ​​the oil receiving cup 300 on the horizontal plane, so that the condensate on the second guide member 110 can flow into the oil receiving cup 300 along the second guide member 110 under the action of its own gravity.

[0065] Specifically, the lower end of the second guide member 110 can be extended to directly above the oil receiving cup 300, so that the portion of the lower end of the second guide member 110 directly above the oil receiving cup 300 can overlap with the projection area of ​​the oil receiving cup 300 on the horizontal plane.

[0066] Preferably, see Figure 4 The second drainage member 110 can be configured as a groove body with two groove walls on the left and right (relative to the orientation of the cook during actual use, not referring to the absolute orientation), and a guide port is provided at the end of the second drainage member 110 close to the oil receiving cup 300. The guide port can be formed by an open arrangement at the end of the second drainage member 110 close to the oil receiving cup 300, or a groove wall can be provided at the end of the second drainage member 110 close to the oil receiving cup 300, and a plurality of through holes are opened on the groove wall, and the through holes are arranged close to the bottom wall of the groove body, so that the condensate on the second drainage member 110 can flow into the oil receiving cup 300 through the through holes, so that the condensate can smoothly flow into the oil receiving cup 300 from the guide port at the end of the second drainage member 110 close to the oil receiving cup 300, and the left and right groove walls of the second drainage member 110 can form a barrier to the condensate, and can prevent the condensate from dripping onto the stove from the upper surface of the second drainage member 110 through both sides.

[0067] As an implementation method, see Figure 3 and Figure 4 The snap assembly 130 can be used to realize the detachable connection between each first drainage member 120 and the smoke collecting hood 200. Therefore, when the drainage assembly 100 needs to be cleaned, the drainage assembly 100 can be removed from the smoke collecting hood 200, which is more convenient to clean and has a better cleaning effect.

[0068] Specifically, the snap-on assembly 130 includes a male component 131 and a female component 132, and the male component 131 and the female component 132 are respectively fixed on the smoke hood 200 and the first drainage component 120. The male component 131 and the female component 132 are matched and connected to realize the connection between the first drainage component 120 and the smoke hood 200. When it is necessary to remove the drainage assembly 100 from the smoke hood 200, the male component 131 and the female component 132 can be directly detached, which is very convenient.

[0069] As another feasible implementation method, each first drainage member 120 can be connected to the smoke hood 200 by means of a telescopic motor or a telescopic cylinder. Thus, when the drainage assembly 100 needs to be cleaned, the telescopic motor or the telescopic cylinder can be controlled to extend so that the drainage assembly 100 can be dropped to a suitable position, making cleaning more convenient and achieving a better cleaning effect. In addition, when the range hood is idle, the telescopic motor or the telescopic cylinder can be controlled to contract so that the drainage assembly 100 can be raised to a higher position, thereby reducing space occupancy, making it look more spacious, and providing a better user experience. When the range hood needs to be used, only the telescopic motor or the telescopic cylinder needs to be controlled to extend so that the drainage assembly 100 can be dropped to a suitable position, so that a sufficient second gap can flow out between the drainage assembly 100 and the smoke hood 200.

[0070] See also Figure 1 - Figure 4 This embodiment also provides a range hood, which includes the above-mentioned drainage assembly 100.

[0071] In summary, the present invention discloses a drainage assembly 100 and a range hood having the same, which overcomes many technical defects of the guide plate on the traditional range hood. The drainage assembly 100 and the range hood having the same provided in this embodiment can well alleviate the problem of poor oil smoke circulation and easy accumulation of oil smoke in the middle area below the range hood, thereby reducing the amount of oil smoke escaping and improving the oil smoke absorption effect.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
