Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a cyclone filter element for a fume hood assembly of a range hood. The present invention also relates to a corresponding fume hood assembly for a range hood and 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 an embodiment of the present invention is to propose an improved cyclone filter for a fume hood assembly of a range hood, which cyclone filter can significantly improve the grease filtering effect of the range hood, has an improved appearance and can be easily assembled in the fume hood assembly of the range hood.

[0005] According to a first aspect of the present invention, a cyclone filter element for a fume hood assembly of a range hood is provided, wherein the cyclone filter element has an air inlet opening downwardly 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.

[0006] Compared with the prior art, in the cyclone filter of the smoke hood assembly for a range hood according to the present invention, the oil fume airflow gathered by the smoke hood assembly can enter the cyclone filter from the air inlet and repeatedly hit the inner wall of the cyclone filter in a spiral manner, so that the grease adheres to the inner wall, and the filtered airflow flows out through the air outlet of the cyclone filter, thereby realizing efficient grease separation. wherein, the first diameter of the first end of the cyclone filter according to the present invention is smaller than the second diameter of the second end, which allows each cyclone filter to be arranged closely to each other with the longitudinal extension axis along the radial direction of the confluence area and simplifies the assembly of the cyclone filter in the smoke hood assembly, and the second end of the cyclone filter can protrude beyond the upper surface of the smoke hood assembly, so that the smoke hood assembly can present the curved and convex shape of the cyclone filter, so that the smoke hood assembly as a whole has a rounded appearance and a unique and novel sense of design.

[0007] Exemplarily, the diameter of the cross section of the cyclone filter element decreases linearly from the second end to the first end. This enables simple and cost-effective production of the cyclone filter element and avoids the generation of gaps between individual cyclone filter elements or between the cyclone filter element and the hood frame of the fume hood assembly. In particular, the first diameter of the first end is half the second diameter of the second end.

[0008] Exemplarily, the cyclone filter is constructed in the form of a hollow cylinder; and / or, the lower end face of the cyclone filter provided with the air inlet is oriented perpendicularly to at least one of the first end and the second end; and / or, the cyclone filter has a curved upper end face and a flat lower end face. This also enables simple and cost-effective manufacturing and assembly of the cyclone filter, and after the cyclone filter is assembled in the smoke hood assembly, allows a flush lower surface of the smoke hood assembly to be achieved and can improve the appearance of the smoke hood assembly.

[0009] For example, the wall thickness of the cyclone filter element is kept 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, thereby enabling cost-effective manufacturing of the cyclone filter element.

[0010] Exemplarily, the cyclone filter is configured with a track portion on the outer peripheral side, and the track portion is configured to be suitable for matching and connecting with the corresponding slide groove portion of another cyclone filter or the hood frame of the smoke hood assembly in a form-locking manner; and / or, the cyclone filter is configured with a slide groove portion on the outer peripheral side, and the slide groove portion is configured to be suitable for matching and connecting with the corresponding track portion of another cyclone filter or the hood frame of the smoke hood assembly in a form-locking manner; and / or, a magnetic suction portion is configured in the cyclone filter, and the magnetic suction portion is configured to be suitable for matching and connecting with the corresponding magnetic suction portion in another cyclone filter or the hood frame of the smoke hood assembly in a magnetic suction manner. This can achieve easy assembly and disassembly of the cyclone filter with another cyclone filter or the hood frame, thereby allowing easy cleaning of the smoke hood assembly, especially the cyclone filter.

[0011] For example, the cyclone filter element omits part of the material at the first end, so that the air outlet is constructed in an inclined split manner, thereby realizing an enlarged, upwardly inclined air outlet of the cyclone filter element, so that the airflow flowing out of the air outlet flows upward and avoids interference of the airflow in the confluence area to generate noise.

[0012] According to a second aspect of the present invention, a fume hood assembly for a range hood is provided, 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 comprises a plurality of cyclone filters according to the present invention, and air outlets of the cyclone filters lead to a confluence area located internally of the fume hood assembly.

[0013] 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. This can significantly improve the appearance of the smoke hood assembly.

[0014] Exemplarily, the smoke 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 the cyclone filter is evenly distributed in the first side portion and the second side portion along the circumferential direction of the smoke hood assembly. In this way, the smoke collection area of ​​the smoke hood assembly can be increased and uniform suction and filtering effects can be achieved along the circumferential direction of the smoke hood assembly.

[0015] Exemplarily, the confluence area is constructed in a sector shape, in particular a semicircular shape; and / or the longitudinal extension axis of at least some of the cyclone filter elements in the cyclone filter element is oriented in the radial direction of the confluence area; and / or the air inlets of at least some of the cyclone filter elements in the cyclone filter element are arranged radially around the confluence area. Depending on assembly requirements, it is also possible that the longitudinal extension axes of at least some of the cyclone filter elements in the cyclone filter element are oriented parallel to each other.

[0016] For example, the longitudinal extension of the cyclone filter element is changed according to the distribution position, so that the first end of the cyclone filter element is distributed in a circular manner around the confluence area, and the second end of the cyclone filter element forms a flush outer peripheral surface of the first side edge portion or the second side edge portion respectively, thereby improving the appearance of the smoke hood assembly.

[0017] For example, the fume hood assembly is arranged to be gradually lowered from front to back when viewed in the depth direction; and / or, when viewed in the radial direction of the confluence area, the longitudinal extension axis of the cyclone filter of the fume hood assembly is arranged to be gradually lowered from outside to inside. As a result, the grease filtered in the cyclone filter is more easily gathered under the action of its own gravity, so as to flow out from the air outlet to the oil box below, thereby preventing the grease from accidentally falling on the stove below.

[0018] Exemplarily, the fume hood assembly is integrally constructed; or at least some 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 that is adhered to grease, which can significantly simplify the cleaning process of the fume hood assembly.

[0019] Exemplarily, at least some of the cyclone filters are arranged closely to each other; and / or, at least some of the cyclone filters are arranged spaced apart from each other, which enables the arrangement of the cyclone filters to be flexibly adjusted according to assembly requirements or requirements for smoke filtering efficiency.

[0020] Exemplarily, the fume hood assembly includes a hood frame, and the cyclone filter element is carried in the hood frame, thereby improving the assembly strength of the fume hood assembly.

[0021] By way of example, the fume hood assembly is symmetrically configured in the width direction, thereby enabling simple and cost-effective production and assembly of the fume hood assembly.

[0022] Exemplarily, the fume hood assembly further comprises an oil box, which is arranged below the confluence area, so as to realize simple collection and cleaning of filtered grease.

[0023] According to a third aspect of the present invention, a range hood is provided, wherein the range hood comprises at least a main body and a fume hood assembly according to the present invention, wherein the fume hood assembly is fixedly arranged on the main body.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Figure 1 A perspective view of a range hood 100 according to an exemplary embodiment of the present invention is shown.

[0038] like Figure 1 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 fixed 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.

[0039] like Figure 1As shown, the smoke hood assembly 20 has 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 25 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.

[0040] like Figure 1 As shown, the smoke hood assembly 20 includes a plurality of cyclone filters 23, wherein the cyclone filters have an air inlet 1 opened downward along the height direction Z and an air outlet 2 opened toward a confluence area 25. The oil fume gas gathered by the smoke hood assembly 20 can enter the cyclone filter 23 through the air inlet 1, and then the oil fume gas repeatedly hits the inner wall of the cyclone filter 23 in a spiral manner, thereby achieving grease separation of the oil fume gas, and the filtered clean airflow enters the confluence area 25 through the air outlet 2 of the cyclone filter 23, thereby keeping the interior of the main body 10 of the range hood 100 clean.

[0041] For example, Figure 1 As shown, the smoke hood assembly 20 may further include a hood frame 24 in which each cyclone filter 23 is carried. The hood frame 24 may improve the assembly strength of the smoke hood assembly 20, thereby preventing the smoke hood assembly 20 from being deformed undesirably.

[0042] Figure 2a and Figure 2b A perspective view and a longitudinal sectional view are respectively shown of a cyclone filter element of a fume hood assembly for a range hood according to an exemplary embodiment of the present invention.

[0043] like Figure 2aAs shown, the cyclone filter 23 is constructed in the form of a hollow cylinder and has an air inlet 1 opened downward along the height direction Z and an air outlet 2 opened in the horizontal direction, wherein the cyclone filter 23 includes a first end 231 and a second end 232 opposite to each other along the longitudinal extension axis L, and the air outlet 2 is arranged at the first end 231. When the cyclone filter 23 is assembled in the smoke hood assembly 20, the first end 231 of the cyclone filter 23 faces the confluence area 25 of the smoke hood assembly 20, and the second end 232 is arranged away from the confluence area 25, so that the air outlet 2 of the cyclone filter 23 is open to the confluence area 25. Here, the cyclone filter 23 has an upper end face 233 and a lower end face 234, and the air inlet 1 is arranged in the lower end face. In particular, the upper end face 233 is constructed in a curved manner and the lower end face 234 is constructed in a flat manner. Of course, other configurations of the cyclone filter 23 can also be considered, such as the lower end face 234 is also constructed in a curved manner.

[0044] like Figure 2b As shown, the first diameter D1 of the first end 231 of the cyclone filter 23 is smaller than the second diameter D2 of the second end 232. When the cyclone filter 23 is assembled in the smoke hood assembly 20, especially when the cyclone filter 23 is arranged closely to each other in a manner that the corresponding longitudinal extension axis L extends along the radial direction of the confluence area 25, the cyclone filter 23 of this configuration is easy to assemble. This is easy to understand, because the inner peripheral side of the first end 231 of the smoke hood assembly 20 where the cyclone filter 23 is arranged has a relatively small diameter, and the inner peripheral side surrounds the confluence area 25, while the outer peripheral side of the second end 232 where the cyclone filter 23 is arranged has a relatively large diameter. When the first diameter D1 of the first end 231 is smaller than the second diameter D2 of the second end 232, it is possible to achieve that the cyclone filter 23 adjacent in the circumferential direction are always arranged close to each other in the longitudinal extension scale. In addition, when the cyclone filter 23 is assembled in the smoke hood assembly 20, the second end 232 of the cyclone filter 23 can protrude beyond the upper surface of the smoke hood assembly 20, so that the user can directly see the curved and raised shape of the cyclone filter 23 in the smoke hood assembly 20, which achieves a rounded appearance and a unique and novel design sense of the smoke hood assembly 20.

[0045] For example, Figure 2a and Figure 2bAs shown, the diameter of the cross section of the cyclone filter 23 decreases linearly from the second diameter D2 to the first diameter D1 from the second end 232 to the first end 231. This enables simple and cost-effective manufacturing and assembly of the cyclone filter 23 and avoids the generation of gaps between the individual cyclone filters 23 or between the cyclone filter 23 and the hood frame 24 of the smoke hood assembly 20 for supporting the cyclone filter 23. Here, the first diameter D1 is, for example, half of the second diameter D2. Of course, other ratios that are considered meaningful by those skilled in the art can also be considered, and the ratios depend on the specific size parameters of the smoke hood assembly 20.

[0046] For example, Figure 2a As shown, the wall thickness of the cyclone filter 23 remains constant in the circumferential direction and / or in the longitudinal extension direction of the cyclone filter 23. This enables a uniform structural strength of the cyclone filter 23. Here, the cyclone filter 23 is an injection molded part manufactured by injection molding. This enables a simple and cost-effective manufacturing process for the cyclone filter 23. Of course, it is also conceivable that the cyclone filter 23 is manufactured from other materials, such as metal.

[0047] For example, Figure 2a As shown, the lower end face 234 of the cyclone filter 23 provided with the air inlet 1 is oriented perpendicularly to at least one of the first end 231 and the second end 232, especially the first end 231, so that when the cyclone filter 23 is assembled in the smoke hood assembly 20, the outer peripheral surface of the smoke hood assembly 20 can be flush and kept vertical, which can enhance the appearance of the smoke hood assembly 20.

[0048] Figure 3a and Figure 3b A front view and a top view of a range hood 100 according to an exemplary embodiment of the present invention are respectively shown. Figure 4 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.

[0049] like Figure 3a and Figure 4As shown, the confluence area 25 of the smoke hood assembly 20 is constructed in a sector shape, especially in a semicircular shape, and the various cyclone filters 23 are arranged around the confluence area 25, and the longitudinal extension axis L in the cyclone filter is oriented in the radial direction of the confluence area 25, so that the air inlet 1 in the cyclone filter 23 is arranged radially around the confluence area 25, which allows the cyclone filter 23, especially the air inlet 1 of the cyclone filter 23, 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. For this reason, the second diameter D2 of the second end 232 of the cyclone filter 23 located on the radial outside is larger than the first diameter D1 of the first end 231 located on the radial inside. However, it is also possible that, according to assembly requirements, the longitudinal extension axes of some cyclone filters in the cyclone filter 23 are parallel to each other and are not oriented in the radial direction of the confluence area 25.

[0050] For example, Figure 3b and Figure 4 As shown, the cyclone filters 23 in the fume hood assembly 20 are arranged closely to each other. This can increase the distribution density of the cyclone filters 23, thereby maximizing the filtering performance of the fume hood assembly 20. However, it is also possible that at least some of the cyclone filters 23 are arranged spaced apart from each other to meet the assembly requirements of the cyclone filters 23.

[0051] For example, the fume hood assembly 20 is integrally constructed of 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 23 are integrally constructed, and these cyclone filters can be assembled in the hood frame 24 of the fume hood assembly 20. In addition, it is also possible that each cyclone filter 23 is individually constructed and assembled in the fume hood assembly 20 in a detachable manner, thereby making it easy to disassemble the cyclone filter 23, thereby achieving simple cleaning of the fume hood assembly 20 and each cyclone filter 23.

[0052] Exemplarily, the cyclone filter 23 is configured with a track portion, which is configured to protrude relative to the side of the cyclone filter 23 and can be matched in a form-locked manner with the corresponding slide groove portion of another adjacent cyclone filter or cover frame 24. At the same time, the cyclone filter 23 can also be configured with a slide groove portion, which is configured to be recessed relative to the side of the cyclone filter 23 and can be matched in a form-locked manner with the corresponding track portion of another adjacent cyclone filter or cover frame 24. When the track portion is inserted into the slide groove portion, the cyclone filter 23 is assembled in a form-locked manner with the adjacent cyclone filter or cover frame 24, and the cyclone filter 23 is prevented from falling from the smoke hood assembly 20 under the action of gravity. Here, the track portion and the slide groove portion can also be correspondingly provided on the side of the cover frame 25.

[0053] For example, a magnetic attraction portion may be configured in the cyclone filter 23, and a corresponding magnetic attraction portion may be configured in another adjacent cyclone filter or cover frame 24, 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 23 in the smoke collecting cover assembly 20.

[0054] For example, Figure 3b and Figure 4 As shown, the second end 232 of the cyclone filter 23 is arranged flush with the outer peripheral surface of the smoke hood assembly 20, so that the smoke hood assembly 20 has flush end surfaces in the first side portions 21 on the left and right sides and the second side portion 22 on the front side, thereby improving the appearance of the smoke hood assembly 20. To this end, the longitudinal extension scale of the cyclone filter 23 changes according to the distribution position, so that the first end 231 of the cyclone filter 23 is distributed in a circular manner around the confluence area 25, and the second end 232 of the cyclone filter 23 respectively forms a flush outer peripheral surface of the first side portion 21 or the second side portion 22. In this case, for example, the longitudinal extension scale of the cyclone filter 23 in the transition area between the first side portion 21 and the second side portion 22 is greater than the longitudinal extension scale of the cyclone filter 23 in the first side portion 21 or the second side portion 22.

[0055] For example, Figure 3a As shown, the upper end surface 233 of the cyclone filter 23 is convexly curved and protrudes beyond the upper surface of the rest of the fume hood assembly 20 , so that the fume hood assembly 20 presents an improved rounded appearance as a whole.

[0056] For example, Figure 3a As shown, the lower end surface 234 of the cyclone filter 23 is flat and flush with the lower surface of the rest of the fume hood assembly 20, thereby achieving an overall flush lower surface of the fume hood assembly 20, which can achieve an optimized appearance and simplify the cleaning process of the fume hood assembly 20.

[0057] For example, Figure 3a and Figure 3bAs shown, viewed along the depth direction Y, the smoke hood assembly 20 is arranged to be gradually lowered from front to back in the height direction Z, so that the cyclone filter 23 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 23 to flow out from the air outlet 2 under the action of its own gravity. In particular, viewed along the radial direction of the confluence area 25, the longitudinal extension axis L of the cyclone filter 23 in the smoke hood assembly 20 is arranged to be gradually lowered from the outside to the inside. This can also promote the grease in the cyclone filter 23 to flow out from the relatively low air outlet 2 under the action of its own gravity, thereby achieving self-cleaning of the cyclone filter 23 as much as possible and avoiding frequent cleaning of the cyclone filter 23.

[0058] For example, Figure 3a and Figure 3b 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 .

[0059] For example, Figure 4 As shown, the first end 231 of the cyclone filter 23 provided with the air outlet 2 surrounds the confluence area 25, and the longitudinal extension axis L of the cyclone filter 23 is oriented along the radial direction of the confluence area, wherein an oil box 26 is arranged below the confluence area 25, and the grease filtered by the cyclone filter flows out from the air outlet 2 into the oil box 26, and the accumulated grease can be easily removed after the oil box 26 is removed to avoid the generation of odor at high temperature.

[0060] For example, Figure 4 As shown, at least part of the cyclone filter 23 omits part of the material at the first end 231, so that the air outlet 2 of the corresponding cyclone filter is constructed in an inclined split manner. In this case, 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 split 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.

[0061] Exemplarily, a fume hood assembly for a range hood is proposed, 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, the side portions at least partially limit a confluence area located inside, the confluence area is configured to be suitable for leading to an air path in the main body, and the fume hood assembly includes a plurality of cyclone filters, the cyclone filters having an air inlet open downwardly and an air outlet open toward the confluence area, wherein the cyclone filter is arranged in each of the side portions.

[0062] Exemplarily, the smoke hood assembly has two first side portions located on the left and right sides along the width direction and a second side portion located on the front side along the depth direction, and there is a transition portion between the first side portion and the second side portion, wherein the cyclone filter element is arranged in the transition portion; and / or the transition portion is rounded in structure.

[0063] Exemplarily, the cyclone filter element is provided with an elastically deformable locking protrusion at an inner end facing the confluence region.

[0064] Exemplarily, 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.

[0065] Exemplarily, the fume hood assembly further includes a lighting unit, and the lighting unit is arranged at a middle position on the front side of the fume hood assembly.

[0066] Exemplarily, the range hood comprises a moving panel, which is arranged below the fume hood assembly and is configured to movably open or close an air inlet of a cyclone filter element of the fume hood assembly.

The feature examples provided in the present disclosure are intended to be illustrative, not limiting, unless otherwise stated.
