Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a fume collecting hood assembly for a range hood. The present invention also relates to a corresponding range hood. Background Art

[0002] In recent years, with the improvement of living standards, range hoods for extracting fumes generated during cooking have become indispensable household appliances. Range hoods are usually installed above kitchen stoves. When in operation, they can collect exhaust gas generated by stove combustion and fumes harmful to the human body generated during cooking through the smoke hood and extract them through the flue, thereby purifying the kitchen environment and reducing pollution.

[0003] The oil fume gas sucked by the range hood contains grease, moisture and solid particles, among which the grease may solidify and accumulate on the housing, fan blades or flue of the range hood, causing the risk of oil leakage of the range hood and affecting the normal operation of the fan, shortening the service life of the range hood. For this reason, the existing range hood is provided with a filter screen, through which the grease is filtered. However, the filter screen is generally difficult to clean. After long-term use, the filtering effect of the filter screen decreases, resulting in grease accumulation and odor at high temperatures, which seriously affects the user's use and cooking experience. Summary of the invention

[0004] Therefore, one purpose of the embodiments of the present invention is to provide an improved fume hood assembly for a range hood, which can fully and efficiently filter the grease in the smoke, thereby keeping the interior of the range hood clean and preventing or delaying the generation of odor, thereby significantly improving the user experience. In addition, the fume hood assembly according to the present invention also has a novel appearance effect.

[0005] According to a first aspect of the present invention, there is provided a fume hood assembly for a range hood, wherein the fume hood assembly is configured to be suitable for being fixedly arranged on the main body of the range hood, wherein the fume hood assembly has at least three side portions, wherein the side portions at least partially define a confluence area located internally, wherein the confluence area is configured to be suitable for leading to an air path in the main body, and the fume hood assembly comprises a plurality of cyclone filters, wherein the cyclone filters have an air inlet open downwardly and an air outlet open toward the confluence area, wherein the cyclone filter is provided in each of the side portions.

[0006] Compared with the prior art, the smoke hood assembly for a range hood according to the present invention is provided with a cyclone filter in each of at least three side portions, so that the smoke airflow gathered by the smoke hood assembly flows through the cyclone filter in the circumferential direction in an all-round manner, wherein the smoke airflow repeatedly hits the inner wall in each cyclone filter in a spiral manner, which realizes efficient grease separation, and the filtered airflow enters the confluence area through the air outlet of the cyclone filter and further flows to the interior of the range hood, thereby keeping the interior of the range hood clean and avoiding or delaying the odor caused by grease accumulation. In addition, by arranging the cyclone filter in each side of the smoke hood assembly, the smoke hood assembly presents a curved and convex shape of the cyclone filter in the circumferential direction, so that the smoke hood assembly as a whole has a rounded appearance and a unique and novel sense of design.

[0007] According to an exemplary embodiment of the present invention, the fume hood assembly has two first side portions located at the left and right sides along the width direction and a second side portion located at the front side along the depth direction, and a transition portion is provided between the first side portion and the second side portion. The smoke collecting area of ​​the fume hood assembly can be increased by the first side portions on the left and right sides and the second side portion on the front side, so as to prevent the oil smoke from escaping into the environment as much as possible, thereby advantageously improving the smoke collecting effect of the range hood.

[0008] According to an exemplary embodiment of the present invention, the cyclone filter is arranged in the transition portion; and / or the transition portion is rounded. This enables the cyclone filter to be more evenly distributed in the smoke hood assembly to improve the smoke filtering effect of the smoke hood assembly. In addition, the smoke hood assembly constructed in this way has a further improved appearance.

[0009] According to an exemplary embodiment of the present invention, the longitudinal extension axis of at least part of the cyclone filter elements is oriented along the radial direction of the confluence area; and / or, the air inlets of at least part of the cyclone filter elements are radially arranged around the confluence area. In this way, the cyclone filter elements, especially the air inlets of the cyclone filter elements, can be evenly distributed in the circumferential direction of the smoke hood assembly, thereby improving the smoke filtering effect of the smoke hood assembly. According to assembly requirements, it is also possible that the longitudinal extension axes of at least part of the cyclone filter elements are oriented parallel to each other.

[0010] According to an exemplary embodiment of the present invention, at least some of the cyclone filter elements are arranged closely to each other; and / or at least some of the cyclone filter elements are arranged spaced apart from each other. This allows the arrangement of the cyclone filter elements to be flexibly adjusted according to assembly requirements or requirements for smoke filtering efficiency.

[0011] According to an exemplary embodiment of the present invention, the smoke hood assembly includes a hood frame, and the cyclone filter is carried in the hood frame. The hood frame can improve the assembly strength of the smoke hood assembly and make the distribution design of the cyclone filter simpler.

[0012] According to an exemplary embodiment of the present invention, the fume hood assembly is integrally constructed; or at least part of the cyclone filters are integrally constructed. This can reduce the number of parts and simplify the assembly process of the fume hood assembly. However, it is also conceivable that the cyclone filters are individually constructed and assembled in the fume hood assembly in a detachable manner, thereby allowing the user to easily remove each cyclone filter from the fume hood assembly to clean the cyclone filter with grease adhered to it, which can significantly simplify the cleaning process of the fume hood assembly.

[0013] According to an exemplary embodiment of the present invention, the cyclone filter is configured with a track portion, and the track portion can be matched with the corresponding slide portion of another cyclone filter or a cover frame in a form-locking manner; and / or, the cyclone filter is configured with a slide portion, and the slide portion can be matched with the corresponding track portion of another cyclone filter or a cover frame in a form-locking manner; and / or, a magnetic attraction portion is configured in the cyclone filter, and a corresponding magnetic attraction portion is configured in another cyclone filter or a cover frame, and the magnetic attraction portion and the corresponding magnetic attraction portion cooperate with each other in a magnetic attraction manner. In this way, easy assembly and disassembly of the cyclone filter and another cyclone filter or a cover frame can be achieved.

[0014] According to an exemplary embodiment of the present invention, the cyclone filter is provided with an elastically deformable locking protrusion at the inner end facing the confluence area, which enables the cyclone filter to be stably assembled in the fume hood assembly and avoids the cyclone filter from falling unexpectedly.

[0015] According to an exemplary embodiment of the present invention, the cyclone filter is made of plastic or metal; and / or the cyclone filter has a curved upper end surface and a flat lower end surface, wherein in the smoke hood assembly, the lower end surfaces of the cyclone filter are flush with each other. This can achieve a flush lower end surface and a curved convex upper end surface of the smoke hood assembly, so that the smoke hood assembly has an improved appearance as a whole.

[0016] According to an exemplary embodiment of the present invention, at least part of the cyclone filter elements has a conical configuration, so that the cross section of the outer end of the cyclone filter element is larger than the cross section of the inner end.

[0017] According to an exemplary embodiment of the present invention, at least part of the cyclone filter has an obliquely cut air outlet at its inner end, thereby achieving an enlarged, upwardly inclined air outlet of the cyclone filter, so that the airflow flowing out of the air outlet flows upward and avoids the airflow colliding in the confluence area to generate noise.

[0018] According to an exemplary embodiment of the present invention, the fume hood assembly is arranged to be gradually lowered from front to back as viewed in the depth direction; and / or, the longitudinal extension axis of the cyclone filter of the fume hood assembly is arranged to be gradually lowered from outside to inside as viewed in the radial direction of the confluence area. This makes it easier for the grease filtered in the cyclone filter to gather under its own gravity and prevents the grease from unexpectedly falling on the stove below.

[0019] According to an exemplary embodiment of the present invention, the fume hood assembly is symmetrically configured in the width direction, thereby achieving simple and cost-effective production and assembly of the fume hood assembly.

[0020] According to an exemplary embodiment of the present invention, the confluence area is fan-shaped, especially semicircular; and / or the fume hood assembly further comprises an oil box, which is arranged below the confluence area. This enables simple collection and cleaning of filtered grease.

[0021] According to an exemplary embodiment of the present invention, the fume hood assembly further comprises a lighting unit, and the lighting unit is arranged at a middle position on the front side of the fume hood assembly.

[0022] According to a second aspect of the present invention, a range hood is provided, wherein the range hood at least comprises a main body and a fume collecting hood assembly according to the present invention.

[0023] According to an exemplary embodiment of the present invention, the fume hood assembly is detachably assembled on the circumferential side or below the main body by bolts; and / or, the range hood includes a movable panel, which is arranged below the fume hood assembly and is configured to movably open or close the air inlet of the cyclone filter element of the fume hood assembly.

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention. Here, for the sake of brevity, elements with the same reference numerals are marked only once in the drawings when necessary.

[0032] It should be understood that, in this document, the expressions "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor should they be understood as implicitly indicating the number of technical features indicated. Features defined as "first" or "second" may explicitly or implicitly indicate that at least one of the features is included.

[0033] In the description of the present embodiment, the words and phrases indicating the orientation or positional relationship, such as "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., are used to illustrate the positional relationship of the constituent elements with reference to the accompanying drawings. This is only for the convenience of describing the present specification and simplifying the description, and does not indicate or imply that the device or element referred to has a specific orientation, is constructed and operates in a specific orientation. Therefore, it cannot be understood as a limitation on the present disclosure. The positional relationship of the constituent elements is appropriately changed according to the direction in which each constituent element is described. Therefore, it is not limited to the words and phrases described in the specification, and can be appropriately replaced according to the circumstances. Here, according to the definition of the XYZ rectangular coordinate system in the accompanying drawings: the X direction corresponds to the width direction of the range hood 100, the Y direction corresponds to the depth direction of the range hood 100, and the Z direction corresponds to the height direction of the range hood 100.

[0034] Figure 1a and Figure 1b Different perspective views of a range hood 100 according to an exemplary embodiment of the present invention are respectively shown. Figure 2 A schematic view of a fume hood assembly 20 for a range hood 100 according to an exemplary embodiment of the present invention is shown.

[0035] like Figure 1a and Figure 1b As shown, the range hood 100 can be installed above a kitchen stove and includes a main body 10 and a smoke hood assembly 20. The smoke hood assembly can be detachably assembled on the side or bottom of the main body 10 by bolts and is connected to the air path in the main body 10 for gas flow. A fan is arranged in the air path, and a negative pressure area is formed by the rotation of the blades of the fan, thereby sucking the oil fume gas below into the smoke hood assembly 20. The smoke hood assembly is configured to gather the oil fume gas to improve the smoke capture rate or operating performance of the range hood 100.

[0036] like Figure 1a and Figure 1b As shown, the smoke hood assembly 20 has at least three side portions 21, 22, and the side portions include, for example, two first side portions 21 located on the left and right sides along the width direction X and a second side portion 22 located on the front side along the depth direction Y. Of course, it is also conceivable that the smoke hood assembly 20 includes other side portions, such as a side portion located on the rear side along the depth direction Y. Here, the two first side portions 21 and the second side portion 22 at least partially define a confluence area 26 located inside the smoke hood assembly 20, and the confluence area is configured to collect the gas gathered and filtered by the smoke hood assembly 20 and can lead to the wind path in the main body 10, so that the suction airflow further flows to the common flue downstream of the wind path.

[0037] like Figure 1a and Figure 1bAs shown, the fume hood assembly 20 includes a plurality of cyclone filters 24, each of which has an air inlet 1 opened downward along the height direction Z and an air outlet 2 opened toward the confluence area 26. The fume gas collected by the fume hood assembly 20 can enter the cyclone filter 24 through the air inlet 1, and then the fume gas repeatedly hits the inner wall of the cyclone filter 24 in a spiral manner, thereby achieving grease separation of the fume gas, and the filtered clean airflow enters the confluence area 26 through the air outlet 2 of the cyclone filter 24, thereby keeping the interior of the main body 10 of the range hood 100 clean. Here, a cyclone filter 24 is provided in each side portion of the side portions 21 and 22. In this case, a portion of the oil fume gas gathered by the fume hood assembly 20 can flow into the cyclone filter 24 in the first side edge portions 21 on the left and right sides, while the other portion flows into the cyclone filter 24 in the second side edge portion 22 on the front side. This can effectively expand the suction and filtration area of ​​the oil fume gas, so that the oil fume airflow gathered by the fume hood assembly 20 can flow through the cyclone filter 24 in the circumferential direction, thereby significantly improving the grease separation efficiency or smoke capture rate of the range hood 100, thereby reducing grease accumulation inside the main body 10 and avoiding or delaying the generation of odor, thereby improving the operating performance of the range hood 100 and extending its service life.

[0038] For example, Figure 1a As shown, there is a transition portion 23 between the first side portion 21 and the second side portion 22, and a cyclone filter 24 is also provided in the transition portion, so that the cyclone filter 24 is more evenly distributed in the circumferential direction in the smoke hood assembly 20 to improve the suction and smoke filtering efficiency of the smoke hood assembly 20. Here, the transition portion 23 can be constructed in a right angle. It is also possible that the transition portion 23 is rounded to improve the appearance of the smoke hood assembly 20 and prevent the user's head from hitting the sharp-angled transition portion and getting injured. For details, please refer to Figure 4 .

[0039] For example, Figure 1b and Figure 2As shown, the confluence area 26 is constructed in a fan shape, especially a semicircular shape, and the longitudinal extension axes of at least some, especially all, of the cyclone filters 24 arranged in each side portion are oriented along the radial direction of the confluence area 26, so that the airflow coming out of the air outlets 2 of these cyclone filters 24 flows toward the center of the confluence area 26 in the radial direction, which avoids the filtering airflows of each cyclone filter 24 from interfering with each other. In particular, the air inlets 1 of at least some of the cyclone filters 24 are arranged radially around the confluence area 26, which allows the cyclone filters 24, especially the air inlets 1 of the cyclone filters 24, to be evenly distributed in the circumferential direction of the smoke hood assembly 20, thereby improving the smoke filtering efficiency of the smoke hood assembly 20. It is also possible that, according to assembly requirements, the longitudinal extension axes of some of the cyclone filters 24 are parallel to each other and are not oriented along the radial direction of the confluence area 26.

[0040] For example, Figure 2 As shown, the fume hood assembly 20 further includes an oil box 27, which is arranged below the confluence area 26. Here, the oil box 27 is constructed in a semicircular shape corresponding to the confluence area 26 and is detachably connected to the confluence area 26. The grease filtered out by the cyclone filter 24 flows and accumulates on the oil box 27, and the accumulated grease can be easily removed after the oil box 27 is removed to avoid the generation of odor at high temperatures.

[0041] For example, Figure 1b As shown, viewed along the depth direction Y, the smoke hood assembly 20 is arranged to be gradually lowered from front to back, so that the cyclone filter 24 arranged in the smoke hood assembly 20 also has a gradually lowering from front to back, thereby allowing the grease filtered out of the cyclone filter 24 to flow out from the air outlet 2 to the oil box 27 located below the confluence area 26 on the rear side under the action of its own gravity, which also simplifies the arrangement and configuration of the oil box 27.

[0042] For example, Figure 2 As shown, viewed along the radial direction of the confluence area 26, the longitudinal extension axis of the cyclone filter 24 of the smoke hood assembly 20 is arranged to gradually decrease from the outside to the inside, which can also cause the grease in the cyclone filter 24 to flow out from the relatively low air outlet 2 to the oil box 27 below under the action of its own gravity, thereby achieving self-cleaning of the cyclone filter 24 as much as possible and avoiding frequent cleaning of the cyclone filter 24. Here, at least part of the cyclone filter 24 has a conical configuration, so that the cross-section of the outer end of the cyclone filter 24 along the longitudinal extension axis is larger than the cross-section of the inner end, thereby easily achieving the arrangement of the longitudinal extension axis of the cyclone filter 24 gradually decreasing from the outside to the inside.

[0043] For example, Figure 2As shown, the inner end of at least part of the cyclone filter 24 has an inclined air outlet 2, so that the air outlet area of ​​the air outlet 2 is increased, thereby improving the air outlet efficiency of the cyclone filter 24, wherein the air flow discharged from the inclined air outlet 2 can flow upward, thereby avoiding the air flows coming out of each cyclone filter 24 from interfering with each other in the confluence area 26 and generating noise.

[0044] For example, Figure 1a and Figure 1b As shown, the cyclone filter 24 has a curved upper end surface and a flat lower end surface, wherein, in the smoke hood assembly 20, the lower end surfaces of the cyclone filter 24 are flush with each other, thereby forming an overall flush lower section of the smoke hood assembly 20, wherein the upper end surface of the cyclone filter 24 at least partially protrudes from the upper surface of the hood frame 25 of the smoke hood assembly 20, so that the smoke hood assembly 20 presents a curved and convex shape of the cyclone filter 24, which can achieve a rounded appearance and a unique and novel design sense of the smoke hood assembly 20.

[0045] For example, Figure 1a and Figure 2 As shown, the cyclone filters 24 are arranged closely to each other. This can increase the distribution density of the cyclone filters 24, thereby improving the suction and filtering performance of the smoke hood assembly 20. However, it is also conceivable that at least some of the cyclone filters 24 are arranged spaced apart from each other to meet the assembly requirements of the cyclone filters 24.

[0046] For example, Figure 1a As shown, the smoke hood assembly 20 may include a hood frame 25 in which each cyclone filter 24 is carried. The hood frame 25 can improve the assembly strength of the smoke hood assembly 20, thereby preventing the smoke hood assembly 20 from being deformed unexpectedly.

[0047] Exemplarily, the fume hood assembly 20 is constructed in one piece from plastic using injection molding technology, which can significantly simplify the assembly process of the fume hood assembly 20. However, it is also conceivable that at least some of the cyclone filters 24 are constructed in one piece, and these cyclone filters can be made of metal and assembled in the hood frame 25 of the fume hood assembly 20. In addition, it is also possible that each cyclone filter 24 is constructed separately and assembled in the fume hood assembly 20 in a detachable manner, thereby making it easy to disassemble the cyclone filter 24, thereby achieving simple cleaning of the fume hood assembly 20 and each cyclone filter 24.

[0048] For example, Figure 1b As shown, the fume hood assembly 20 further includes a lighting unit 28, which is arranged in the middle of the front side of the fume hood assembly 20. The lighting unit can clearly display the stove area below.

[0049] For example, Figure 1a and Figure 1b As shown, the fume hood assembly 20 is symmetrically configured in the width direction X, thereby enabling simple and cost-effective production and assembly of the fume hood assembly 20 .

[0050] Figure 3a and Figure 3b An assembly view and a disassembly view of a cyclone filter element 24 of a fume hood assembly 20 according to an exemplary embodiment of the present invention are respectively shown.

[0051] like Figure 3a and Figure 3b As shown, the cyclone filter 24 is configured with a track portion 3, which is configured to protrude relative to the side of the cyclone filter 24 and can be matched in a form-locked manner with the corresponding slide groove portion 4 of another adjacent cyclone filter or cover frame 25. At the same time, the cyclone filter 24 can also be configured with a slide groove portion 4, which is configured to be recessed relative to the side of the cyclone filter 24 and can be matched in a form-locked manner with the corresponding track portion 3 of another adjacent cyclone filter or cover frame 25. When the track portion 3 is inserted into the slide groove portion 4, the cyclone filter 24 is assembled in a form-locked manner with the adjacent cyclone filter or cover frame 25, and the cyclone filter 24 is prevented from falling from the smoke hood assembly 20 under the action of gravity. Here, the track portion 3 and the slide groove portion 4 can also be correspondingly arranged on the side of the cover frame 25.

[0052] For example, a magnetic attraction portion may be configured in the cyclone filter 24, and a corresponding magnetic attraction portion may be configured in another adjacent cyclone filter or cover frame 25, and the magnetic attraction portion and the corresponding magnetic attraction portion may cooperate with each other in a magnetic attraction manner, thereby achieving a fixed position of the cyclone filter 24 in the smoke collecting cover assembly 20.

[0053] Exemplarily, the cyclone filter 24 is provided with an elastically deformable locking protrusion at the inner end facing the confluence area 26. When the cyclone filter 24 is assembled in the smoke hood assembly 20, the position of the cyclone filter 24 in the radial direction along the confluence area 26 is fixed by the locking protrusion, thereby reliably avoiding the cyclone filter 24 from unexpectedly falling off.

[0054] Figure 4 A perspective view of a range hood 100 according to another exemplary embodiment of the present invention is shown.

[0055] like Figure 4As shown, the transition portion 23 between the first side portion 21 and the second side portion 22 of the fume hood assembly 20 is rounded, and a cyclone filter 24 is arranged in the transition portion, thereby achieving uniform suction and filtering performance of the fume hood assembly 20 in the circumferential direction.

[0056] like Figure 4 As shown, the longitudinal extension axes of the cyclone filters 24 in the first side portion 21 and the second side portion 22 of the smoke hood assembly 20 are oriented parallel to each other, and the cyclone filters 24 located in each side portion are arranged closely to each other. Here, these cyclone filters 24 can be constructed as a whole and assembled together into the hood frame 25. However, it is also conceivable that the cyclone filters 24 are constructed separately from each other and assembled together in a detachable manner.

[0057] like Figure 4 As shown, the longitudinal extension axis of the cyclone filter 24 in the transition portion 23 is oriented in the radial direction of the confluence area 26, wherein the cyclone filters 24 are arranged spaced apart from each other in the cover frame 25. In this case, the cross-section of the outer end of the cyclone filter 24 along the longitudinal extension axis can be the same as the cross-section of the inner end, which can simplify the manufacture of the cyclone filter 24.

[0058] Exemplarily, the range hood 100 may further include a moving panel, which is arranged below the fume hood assembly 20 and is configured to movably open or close the air inlet 1 of the cyclone filter 24 of the fume hood assembly 20. The moving panel can prevent foreign matter in the environment from unexpectedly entering the cyclone filter 24.

[0059] Exemplarily, a cyclone filter element for a fume hood assembly of a range hood is proposed, wherein the cyclone filter element has an air inlet opening downward and an air outlet opening in a horizontal direction, wherein the cyclone filter element includes a first end and a second end opposite to each other along a longitudinal extension axis, and the air outlet is arranged at the first end, wherein a first diameter of the first end is smaller than a second diameter of the second end.

[0060] Exemplarily, a diameter of a cross section of the cyclone filter element decreases linearly from the second end to the first end; and / or the first diameter is half of the second diameter.

[0061] Exemplarily, the cyclone filter element is constructed in the form of a hollow cylinder; and / or, the lower end face of the cyclone filter element provided with the air inlet is oriented perpendicular to at least one of the first end face and the second end face; and / or, the cyclone filter element has a curved upper end face and a flat lower end face.

[0062] Exemplarily, the wall thickness of the cyclone filter element remains constant in the circumferential direction and / or in the longitudinal extension direction; and / or, the cyclone filter element is an injection-molded part manufactured by injection molding.

[0063] Exemplarily, the cyclone filter element omits some material at the first end, so that the air outlet is configured to be cut away obliquely.

[0064] Exemplarily, the second end of the cyclone filter is arranged flush with the outer peripheral surface of the smoke hood assembly; and / or the upper end surface of the cyclone filter protrudes beyond the upper surface of the rest of the smoke hood assembly; and / or the lower end surface of the cyclone filter is flush with the lower surface of the rest of the smoke hood assembly.

[0065] Exemplarily, the longitudinal extension dimension of the cyclone filter element changes according to the distribution position, so that the first end of the cyclone filter element is circularly distributed around the confluence area, and the second end of the cyclone filter element respectively forms a flush outer peripheral surface of the first side portion or the second side portion.

[0066] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even when only a single embodiment is described with respect to specific features. The feature examples provided in the present disclosure are intended to be illustrative, not limiting, unless otherwise stated. In specific implementations, multiple features may be combined with each other as required and as technically feasible. Various substitutions, changes, and modifications may also be conceived without departing from the spirit and scope of the present invention.
