Description

Technical Field

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

[0002] Range hoods are common kitchen appliances that effectively remove cooking fumes. Most range hoods use a fan as their main power source. When the range hood is working, the fumes entering the hood are discharged into the external flue through a check valve by the centrifugal force of the fan's rotating impeller.

[0003] However, the existing range hood casing is not strong enough, and it is prone to deformation during transportation. Utility Model Content

[0004] This application addresses the shortcomings of existing methods by providing a casing and a range hood to solve the technical problems of insufficient casing strength in existing range hoods, which easily lead to casing defects during transportation.

[0005] In the first aspect, embodiments of this application provide a housing for use in a smoke hood. The housing mainly includes a left side plate, a back plate, and a right side plate connected at an angle to form a front-concave and rear-convex structure. The left side plate and the right side plate both extend outward from back to front and from top to bottom relative to the back plate. The back plate has multiple layers of molding, and two of the multiple layers of molding have opposite molding directions.

[0006] As an optional implementation, the back panel includes a panel body, a first lamination, and a third lamination. The first lamination is formed on the panel body and has a shape similar to that of the panel body and protrudes outward from the panel body. The third lamination is located in the middle of the first lamination and is formed on the first lamination and is recessed inward from the first lamination.

[0007] As an optional implementation, the third lamination is elongated and extends along the height direction of the first lamination.

[0008] As an optional implementation, the plate is trapezoidal, with the upper base shorter than the lower base.

[0009] As an optional implementation, both the left and right side plates are trapezoidal, with the upper base of both the left and right side plates being longer than the lower base.

[0010] As an optional implementation, the back panel further includes at least one second laminate, the shape of which is similar to that of the panel and is formed on the first laminate, the second laminate protruding outward from the first laminate.

[0011] As an optional implementation, the housing further includes a top plate, a bottom plate, and a front fold. Both the top and bottom plates are connected to the left side plate, the back plate, and the right side plate; the front fold is formed at the front edge of the bottom plate and extends upwards.

[0012] As an optional implementation, the top edge of the front fold is bent inward to form an arc-shaped top.

[0013] As an optional implementation, the height of the front fold is greater than or equal to 15 mm and less than or equal to 25 mm.

[0014] Secondly, this application provides a range hood, including an air inlet plate and a housing and air inlet plate as described in any of the foregoing embodiments. The air inlet plate is fixed to the front side of the housing, and the bottom end of the air inlet plate is disposed on the back side of the front folded edge of the housing, forming an oil leakage cavity between the front folded edge and the air inlet plate.

[0015] This application provides a housing and a range hood. The technical solution provided by the embodiments of this application brings at least the following beneficial effects:

[0016] The back panel has at least two molding layers, one of which protrudes outward and the other protrudes inward. One molding layer is formed on top of the other molding layer.

Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term “and / or” as used herein includes all or any units and all combinations thereof of one or more associated listed items.

[0036] like Figure 1-3 As shown, this application provides a housing for use in a smoke hood. The housing mainly includes a left side plate 1, a back plate 2, and a right side plate 3 connected at an angle to form a front-concave and rear-convex structure. The left side plate 1 and the right side plate 3 both extend outward from back to front and from top to bottom relative to the back plate 2. The back plate 2 has multiple layers of molding, and two of the layers have opposite molding directions.

[0037] In this embodiment, the outer shell is disposed on a horizontal plane. The front side of the outer shell is open. The back plate 2 is vertically disposed and has at least two layers of molding, one of which protrudes outward and the other protrudes inward. One layer of molding is formed on top of the other layer of molding. The strength of the back plate 2 is increased by molding in both directions, which further enhances the strength of the outer shell and prevents the outer shell from deforming during transportation.

[0038] like Figure 1-3 As shown, in one optional embodiment, the back panel 2 includes a panel 21, a first lamination 22, and a third lamination 24. The first lamination 22 is formed on the panel 21, and the shape of the first lamination 22 is similar to the shape of the panel 21 and protrudes outward from the panel 21. The third lamination 24 is located in the middle of the first lamination 22, and the third lamination 24 is formed on the first lamination 22 and is recessed inward from the first lamination 22.

[0039] Based on the aforementioned embodiments, in this embodiment, the first lamination 22 protrudes outward along the thickness direction of the plate 21, i.e., protrudes backward. The first lamination 22 can effectively disperse internal stress, and at the same time, the first lamination 22 strengthens the back plate 2. The outward protrusion of the lamination can increase the volume of the smoke collection chamber, thereby increasing the air intake area, effectively improving performance, reducing the speed of the motor and impeller, and achieving the purpose of increasing air volume and reducing noise.

[0040] The third lamination 24 is centrally located and is a reverse lamination relative to the first lamination 22, meaning it bulges inwards and forwards. This reverse lamination design of the first lamination 22 and the third lamination 24 enhances the strength of the back panel 2.

[0041] In some embodiments, the back panel 2 includes a plurality of third laminations 24, which are evenly distributed.

[0042] As an alternative implementation, the third lamination 24 is elongated and extends along the height direction of the first lamination 22.

[0043] Based on the aforementioned embodiments, in this embodiment, the first lamination 22 extends in the left and right directions, and the third lamination 24 extends in the vertical direction to enhance the strength of the back panel 2 in both the lateral and longitudinal directions.

[0044] As an optional implementation, the plate 21 is trapezoidal, with the upper base shorter than the lower base.

[0045] Based on the aforementioned embodiments, in this embodiment, the first lamination 22 is also trapezoidal, and the upper bottom edge of the first lamination 22 is shorter than the lower bottom edge, so as to adapt to other structures of the outer shell.

[0046] like Figure 1-3As shown, in one optional implementation, both the left side plate 1 and the right side plate 3 are trapezoidal, and the upper base of both the left side plate 1 and the right side plate 3 is longer than the lower base.

[0047] Based on the aforementioned embodiments, in this embodiment, both the left side panel 1 and the right side panel 3 are flat plates. The left side panel 1 extends forward and to the left relative to the back panel 2, and the right side panel 3 extends forward and to the right relative to the back panel 2. The left side panel 1 and the right side panel 3 are inclined relative to the back panel 2 to avoid sharp corner structures, thus preventing deformation of sharp corners due to collisions during transportation. In addition, the inclined design saves more material than the right-angle design, thereby reducing production costs.

[0048] like Figure 1-3 As shown, as an optional implementation, the back plate 2 further includes at least one second lamination 23, the shape of which is similar to that of the plate body 21 and is formed on the first lamination 22, the second lamination 23 protruding outward from the first lamination 22.

[0049] Based on the aforementioned embodiments, in this embodiment, the second lamination 23 is trapezoidal, with its upper base shorter than its lower base. The back panel 2 includes four second laminations 23, arranged in two layers. The two upper second laminations 23 are smaller and distributed horizontally, while the two lower second laminations 23 are larger and distributed horizontally. The second lamination 23 is applied based on the first lamination 22, further strengthening the structure and reducing manufacturing difficulty, as excessive stretching can lead to stress concentration. The second lamination 23 also protrudes outwards, increasing the cross-sectional area between the air inlet and the back panel 2 while increasing the air intake area of ​​the first lamination 22, thereby improving airflow and reducing noise.

[0050] Two second-layer moldings 23 are respectively positioned on opposite sides of the third-layer molding 24, i.e., on the left and right sides. The third-layer molding 24 is molded along the edges of the second-layer moldings 23, and this boundary molding further enhances the strength of the back panel 2. In addition, the centrally located third-layer molding 24 has no air inlet on its front side, which has a minimal impact on the air intake area and avoids any adverse effects on performance.

[0051] like Figure 2 As shown, in one optional embodiment, the housing also includes a top plate 4, a bottom plate 5, and a front folded edge 6. The top plate 4 and the bottom plate 5 are both connected to the left side plate 1, the back plate 2, and the right side plate 3; the front folded edge 6 is formed on the front edge of the bottom plate 5 and extends upward.

[0052] Based on the aforementioned embodiments, in this embodiment, a flange is provided along the edge of the shell opening, wherein the flange on the front side of the bottom plate 5 is the front folded edge 6 of this application, which serves as a retaining wall to prevent oil stains from overflowing from the inside of the shell.

[0053] like Figure 5 As shown, as an optional implementation, the top of the front folded edge 6 is bent inward to form an arc-shaped top.

[0054] Based on the aforementioned embodiments, in this embodiment, the arc-shaped top can effectively prevent internal oil from crawling out of the front fold 6, which would cause oil leakage, and at the same time prevent the appearance of sharp structures, avoiding scratches.

[0055] As an optional implementation, the height of the front fold 6 is greater than or equal to 15 mm and less than or equal to 25 mm.

[0056] Based on the same inventive concept, this application provides a range hood, which mainly includes an air inlet plate and a housing and an air inlet plate 7 as described in any of the foregoing embodiments. The air inlet plate 7 is fixed to the front side of the housing, and the bottom end of the air inlet plate 7 is disposed on the back side of the front folded edge 6 of the housing, forming an oil leakage cavity A between the front folded edge 6 and the air inlet plate 7.

[0057] like Figure 4-5 As shown, based on the aforementioned embodiments, in this embodiment, the range hood includes a smoke collection hood, which mainly comprises a housing, an air inlet plate 7, and a liner plate 8. Both the liner plate 8 and the air inlet plate 7 are fixed to the opening of the housing. The liner plate 8 is higher than the air inlet plate 7, and the liner plate 8, the air inlet plate 7, and the housing together form a smoke collection chamber. Both the liner plate 8 and the air inlet plate 7 are screwed to the housing. The air inlet plate 7 has multiple air inlets, which are opened horizontally, for example, two air inlets distributed left and right.

[0058] The front folded edge 6, the bottom plate 5 of the outer casing, and the air inlet plate 7 form an oil leakage cavity A. The air inlet plate 7 is tilted downwards and backwards as a whole, and the bottom end of the air inlet plate 7 is also provided with an oil guide surface facing the front folded edge 6 to guide the oil sludge to flow into the oil leakage cavity A. The oil sludge in the fume hood slides down into the oil leakage cavity A at the bottom of the fume hood under the action of gravity, so as to collect the oil sludge for regular cleaning.
