The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0030] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0031] This utility model embodiment provides an oil filter assembly 200, which is used in a range hood. The range hood includes a housing 100 with an air inlet, and the oil filter assembly 200 is disposed at the air inlet.

[0032] See Figures 1 to 3 The oil filter assembly 200 of this embodiment includes a plate 1, elongated oil holes 2, and a flange 3. The plate 1 has a first surface and a second surface facing each other, with the first surface facing the air inlet direction. When the range hood is working, the airflow enters the housing 100 from one side of the first surface through the elongated oil holes 2. Multiple elongated oil holes 2 are longitudinally arranged on the plate 1. The oil intercepted by the oil filter flows downward along both sides of the elongated oil holes 2 and eventually flows into the oil cup 140 below. The width of the lower end of the elongated oil holes 2 gradually decreases from top to bottom, forming a first contraction section 21. The gradual decrease in width of the first contraction section 21 from top to bottom allows the oil on both sides of the elongated oil holes 2 to collect and accelerates the flow of oil, making the oil filter guide the oil more smoothly and reducing oil accumulation in the filter.

[0033] A flange 3 is located at the edge of the elongated oil hole 2, outside the first portion. The flange 3 protrudes from the plate 1 towards the second surface. The first portion includes at least part or all of the first contraction section 21 from bottom to top. Providing a flange 3 at the edge of the elongated oil hole 2 enhances the overall strength of the oil mesh and guides airflow. The absence of a flange 3 in the first portion of the elongated oil hole 2 reduces the accumulation area of ​​oil at the bottom of the hole, thus reducing the amount of oil accumulated.

[0034] In the oil filter assembly 200 of this utility model embodiment, a plurality of elongated oil holes 2 are longitudinally arranged on the plate 1. The first surface of the plate 1 faces the air inlet direction. A flange 3 is provided at the edge of the elongated oil holes 2 outside the first part. The flange 3 protrudes from the plate 1 towards the second surface. The first part includes at least a portion of the first contraction section 21 from bottom to top. The width of the lower end of the elongated oil hole 2 gradually decreases from top to bottom, forming the first contraction section 21. During operation, the airflow carries oil fumes from the first surface... The oil enters the range hood through the elongated oil hole 2. The oil adhering to the oil screen flows downward. The first contraction section 21 can collect the oil on both sides of the elongated oil hole 2 and speed up the oil guiding speed, which is conducive to the oil flowing into the oil cup 140 below, reducing the amount of oil accumulation on the oil screen. The lower end of the elongated oil hole 2 does not have a flange, which reduces the oil accumulation area. This embodiment of the utility model reduces the amount of oil hanging on the oil screen and improves the situation where oil drips easily onto the stove when the oil cup 140 is removed under negative pressure or during cleaning.

[0035] In some embodiments, the flange 3 is a folded edge formed by stamping the plate 1. By stamping the plate 1, a folded edge is formed at the edge of the elongated through hole, which makes the flange 3 and the plate 1 an integral structure, and the process is simple and easy to manufacture.

[0036] In some embodiments, see Figure 1 The width of the upper end of the elongated oil hole 2 gradually decreases from bottom to top, forming a second contraction section 22. The second contraction section 22 facilitates the flow of oil above the elongated oil hole 2 to both sides of the elongated oil hole 2, reducing the deposition of oil on the oil mesh.

[0037] In some embodiments, see Figure 1 and Figure 2 The edges of the holes on both sides of the first contraction section 21 can gradually converge in a straight line or in a curved line. The shape of the first contraction section 21 can be V-shaped or U-shaped.

[0038] In some embodiments, see Figure 1 and Figure 2 The edges of the holes on both sides of the second contraction section 22 can gradually converge in a straight line or in a curved line. The shape of the second contraction section 22 can be an inverted V-shape or an inverted U-shape.

[0039] In some embodiments, see Figure 1 and Figure 2 The oil filter assembly 200 of this embodiment further includes a first snap-fit ​​structure 5, which is disposed on the first side of the plate 1 and is used to cooperate with a second snap-fit ​​structure on the housing 100 of the range hood, so that the first side is snapped into the housing 100 of the range hood. The oil filter assembly 200 is connected to the housing 100 of the range hood through the first snap-fit ​​structure 5, which facilitates installation and disassembly.

[0040] In some embodiments, see Figure 2 The oil filter assembly 200 of this embodiment further includes a connecting plug 4, located on the second side of the plate 1, for engaging with an elastic locking structure on the housing 100 of the range hood, so that the second side is connected to the housing 100 of the range hood, with the second side opposite to the first side. The oil filter assembly 200 is connected to the housing 100 of the range hood via the connecting plug 4 and the elastic locking structure, facilitating installation and disassembly.

[0041] The first side of the plate 1 is engaged with the housing 100 of the range hood through the first snap-fit ​​structure 5 and the second snap-fit ​​structure, and the second side is engaged with the housing 100 of the range hood through the connecting plug 4 and the elastic locking structure. The oil filter assembly 200 can be installed to the air inlet or removed from the air inlet without the need for screwdrivers or other tools.

[0042] In some embodiments, see Figure 1 and Figure 2 The first snap-fit ​​structure 5 includes a first snap-fit ​​plate that abuts against the inner side of the range hood housing 100. The second snap-fit ​​structure includes a second snap-fit ​​plate that abuts against the second surface of the plate 1. During installation, align the first side of the plate 1 with the lower side of the air inlet, insert the first snap-fit ​​plate into the air inlet. Because the second snap-fit ​​plate on the range hood housing 100 restricts the plate 1 from moving inwards, and the action of the first snap-fit ​​plate against the range hood housing 100 restricts the plate 1 from moving outwards, the first side is snapped into the range hood housing 100. Pushing the second side of the plate 1 engages the connecting plug 4 with the elastic locking structure, connecting the second side to the range hood housing 100, allowing the oil filter assembly 200 to be installed at the air inlet. During disassembly, first pull the second side of the plate 1 outward from the housing 100 of the range hood to disengage the connecting plug 4 from the elastic locking structure, and then move the plate 1 diagonally upward to remove the oil filter assembly 200 from the air inlet.

[0043] In some embodiments, the first snap-fit ​​plate may be formed by bending the first side of the plate body 1. The first snap-fit ​​plate may be located in the middle of the first side.

[0044] The second snap-fit ​​plate can be formed by bending the inner edge of the air inlet. There can be two or more second snap-fit ​​plates. When the oil filter assembly 200 is installed at the air inlet, the second snap-fit ​​plates can be located on both sides of the first snap-fit ​​plate.

[0045] In some embodiments, see 2 and Figure 3 The second side of the plate 1 has a folded edge structure 11, and a fixing groove 12 is formed between the folded edge structure 11 and the plate 1. The opening of the fixing groove 12 faces the first side. See also Figure 3 The connector 4 includes a connector base 41 and a plug 42 connected to the connector base 41. The connector base 41 is embedded in the fixing groove 12 and fixed by screws. The side wall of the plug 42 has a positioning groove 43. The elastic locking structure includes a positioning element, which cooperates with the positioning groove 43 under the action of elastic force. The second side has a folded edge structure 11, which forms a fixing groove 12 with the plate 1, which facilitates the connection of the connector 4 to the plate 1 and ensures a high connection strength.

[0046] The folded edge structure 11 on the second side can increase the strength of the plate 1. Each of the four sides of the plate 1 can have a folded edge structure 11 to increase the strength of the plate 1.

[0047] The connector 4 has a positioning groove 43. When engaged with the elastic locking structure, the positioning member is embedded in the positioning groove 43 under elastic force, thereby connecting the second side of the plate 1 to the housing 100 of the range hood. During disassembly, pulling the second side of the plate 1 disengages the positioning member from the positioning groove 43, and the connector 4 is released from the elastic locking structure.

[0048] The positioning element may include two spring arms made of elastic material, each spring arm having a protrusion, the protrusions on the two spring arms being arranged opposite each other. When the connector 4 is inserted between the two spring arms, the spring arms undergo elastic deformation. When the protrusions align with the positioning grooves 43, the spring arms return to their original shape, causing the protrusions to embed into the positioning grooves 43. Pulling the second side outward causes the spring arm to undergo elastic deformation, and the protrusions disengage from the positioning grooves 43.

[0049] The positioning component may also include a positioning seat, which comprises two opposing positioning brackets with a gap between them. Each positioning bracket has a locking hole containing a spring and a locking ball. When the connector 4 is inserted between the two positioning brackets, the spring undergoes elastic deformation. When the locking ball aligns with the positioning groove 43, it is embedded in the groove 43 under the action of the spring. Pulling the second side outward causes the spring to elastically deform, dislodging the locking ball from the positioning groove 43.

[0050] In some embodiments, see Figure 2 The folded edge structure 11 has a notch, through which the plug 42 passes. By providing the notch, the connector 41 can be fully embedded in the fixing groove 12, improving the connection strength.

[0051] See Figures 4 to 6 This utility model provides a range hood, including a housing 100 with an air inlet, and an oil filter assembly 200 disposed at the air inlet.

[0052] In some embodiments, see Figure 5 and Figure 6 The housing 100 includes a top and rear plate 110 and two side plates 120, which are disposed opposite each other on both sides of the top and rear plate 110. The top and rear plate 110 includes a top plate 111, a rear plate 112, and a bottom plate 113, all formed by bending a single integral structure. The bottom plate 113 has a first flange 114 bent upwards on the side away from the rear plate 112. The lower sides of the two side plates 120 each have a second flange 121 bent inwards into the housing 100. The rear side of the second flange 121 has a third flange 122 bent upwards, which fits into the first flange 114. By fitting the third flange 122 into the first flange 114, the side plates 120 are connected to the top and rear plate 110, allowing them to fit tightly together and improving the situation where oil leaks from the bottom. The third flange 122 and the first flange 114 can be connected by at least one method, such as welding or riveting.

[0053] In some embodiments, see Figure 6 The upper part of the first fold 114 has a fourth fold 115 formed by bending forward. The fourth fold 115 gradually slopes upward from back to front and is located above the third fold 122. By setting the fourth fold 115, oil can be guided into the groove formed by the rear plate 112, the bottom plate 113 and the first fold 114, and flow into the oil cup 140 at the bottom.

[0054] In some embodiments, after the top rear panel 110 and the side panels 120 are connected by welding and / or riveting, they can be sprayed to seal the joint and prevent oil from leaking from the joint.

[0055] Range hoods may also include a flap 130.
