Description

Technical Field

[0001] This utility model relates to a range hood, and more particularly to an oil filter for a range hood. Background Technology

[0002] Currently, the existing technology, Chinese Patent 202311826224.3, discloses a rapid condensation oil fume separation mesh and a range hood. This oil fume separation mesh includes a mesh body with multiple air inlet zones and multiple guide walls on its front side. The guide walls are recessed rearward, and their edges extend to the air inlet zones to guide oil fumes from the front of the mesh body to these zones. Compared to the prior art, this application abandons the convex arc-shaped guide surface design of the prior art and innovatively sets the guide walls to a recessed rearward configuration. This allows oil fumes from the front of the mesh body to contact the guide walls, reducing their flow velocity and guiding them to the air inlet zones. This prolongs the time the oil fumes pass through the guide walls, allowing more fumes to adhere to them, thus enhancing the oil fume separation effect. However, the problem is that there is a risk of poor oil separation and smoke overflow. Utility Model Content

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 , Figure 2 As shown, a rapid condensation oil fume separation mesh includes a front mesh body 1 and a rear mesh body 2. The front mesh body 1 includes a front square frame 11, a front arc-shaped cavity 12 with a rear opening, a front longitudinal separation plate 13 and a front longitudinal seat plate 14 disposed on the front arc-shaped cavity 12. The front longitudinal seat plate is disposed between two adjacent arc-shaped cavities 12. Two front longitudinal smoke holes 141 are disposed on the front longitudinal seat plate 14 along the longitudinal direction. The front longitudinal separation plate 13 is connected to the arc top of the front arc-shaped cavity 12. The rear mesh body 2 includes a front-opening main body 21, a rear semi-circular arc cavity 22, a front-opening rear arc cavity 23, and a rear longitudinal seat plate 24. The rear semi-circular arc cavity 22, the front-opening rear arc cavity 23, and the rear longitudinal seat plate 24 are located inside the rear part of the main body 21. The rear longitudinal seat plate 24 is provided with two rear longitudinal smoke holes 241 arranged longitudinally. The rear semi-circular arc cavity 22, the rear longitudinal seat plate 24, and the rear arc cavity 23 are located inside the rear part of the main body 21. The rear semi-circular arc cavity 22 and the rear arc cavity 23 are connected by the rear longitudinal seat plate 24, and two adjacent rear arc cavities 23 are connected by the rear longitudinal seat plate 24. The front mesh body 1 is embedded in the main body 21 and is detachably connected. The front longitudinal seat plate 14 extends into the rear arc-shaped cavity 23. The rear longitudinal seat plate 24 between the rear semi-arc-shaped cavity 22 and the rear arc-shaped cavity 23, and the rear longitudinal seat plate 24 between the rear arc-shaped cavities 23, extend into the front arc-shaped cavity 12. The gap between two adjacent front longitudinal seat plates 14 forms a longitudinal negative pressure zone. The front longitudinal separation plate 13 has the function of separating oil fumes. The setting of the longitudinal negative pressure zone prevents oil fumes from shaking and allows them to quickly enter the front longitudinal smoke hole 141. The front longitudinal separation plate 13 also acts as a wind-cooled radiator, condensing oil fumes.

[0023] As a further improvement of this utility model: a rear longitudinal separation plate 25 is provided inside the rear arc-shaped cavity 23, which is opposite to the front longitudinal smoke hole 141. The rear longitudinal separation plate 25 has the function of separating oil fumes. With this structure, the oil fumes from the front longitudinal smoke hole 141 collide with the rear longitudinal separation plate 25, achieving oil fume separation. At the same time, the oil fumes are diverted to the rear arc-shaped cavities 23 on both sides of the longitudinal separation plate 25; then, they enter the front arc-shaped cavity 12, and finally enter the casing of the range hood through the rear longitudinal smoke hole 241.

[0024] As a further improvement of this utility model: the width of the front longitudinal separation plate 13 gradually increases from bottom to top. With this structure, the volume of the longitudinal negative pressure zone gradually increases from bottom to top, effectively preventing smoke overflow. When used with the oil filter, it typically forms an angle of less than 90 degrees with the horizontal plane below it, and is closer to the part of the stove with the most oil fumes.

[0025] As a further improvement to this utility model: such as Figure 5 , Figure 7 As shown, the front ends of the two side walls of the rear longitudinal smoke hole 241 are wavy or toothed. With this structure, the oil fumes are separated again before entering the casing of the range hood.

[0026] As a further improvement of this utility model: the main body 21 of the rear mesh 2 includes an oil guiding cavity 26 with an upper opening, a rear opening and a lower opening at the bottom, a support plate 27 in the oil guiding cavity and locking holes 28 on both sides of the upper part. The lower end of the front mesh body 1 is provided with a slot 15, and the upper two ends of the rear part are provided with locking seats 16, and also includes positioning beads 3; Positioning bead 4 is located on locking seat 16, and slot 15 and support plate 27 are fitted together. Locking seat 16 passes through locking hole 28, and positioning bead 3 cooperates with main body 21. With this structure, front mesh 1 is easy to disassemble and assemble.

[0027] As a further improvement of this utility model: the bottom frame edge of the front square frame 11 is provided with an oil guiding slope 111, and the guiding slope 111 extends into the oil guiding cavity. Figure 3 As shown, the oil guiding slope 111 forms an acute angle α with the horizontal plane in front. With this structure, the oil on the front mesh body 1 flows down from top to bottom and all enters the oil guiding cavity.

[0028] like Figure 8 As shown, the front mesh body 1 is provided with a handle 3; the handle 3 is provided with anti-slip recesses 31 on both sides.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
