[0002] In modern kitchen environments, the oil fume problem has always been an important factor affecting air quality and kitchen comfort. Traditional oil fume exhaust systems usually rely on exhaust fans and oil fume purifiers to exhaust oil fume outdoors through strong exhaust. However, these systems often have problems such as high noise, low exhaust efficiency, and incomplete oil fume treatment.

[0003] The silencing condensing oil fume wind off-grid technology is a new oil fume treatment method that combines silencing, condensation and oil fume purification technologies. It aims to improve the oil fume treatment effect while reducing noise pollution and improving the working efficiency of the exhaust system. By introducing a condensation link in the oil fume emission process, this technology can effectively separate the oil mist and water vapor in the oil fume and reduce pollution to the environment. At the same time, through the design of the silencer, the noise generated by the fan operation can be reduced, improving the comfort of the kitchen working environment.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a sound-absorbing condensing oil fume wind separator, comprising a rectangular outer frame 1, a handle 2 is provided on the front of the rectangular outer frame 1, specifically, an area for mounting the handle 2 which is integrally formed with the rectangular outer frame 1 is provided in the middle of the upper front part of the rectangular outer frame 1, the handle 2 can be fixed to the rectangular outer frame 1 by welding, and can also be fixed to the rectangular outer frame 1 by bolts, so as to facilitate the taking and placing of the entire oil fume wind separator, the inner cavity of the rectangular outer frame 1 is provided with a plurality of aluminum bars 1 3 and a plurality of aluminum bars 2 4 and two mounting plates 5 for fixing the plurality of aluminum bars 1 3 and the aluminum bars 2 4, the plurality of aluminum bars 1 3 and the plurality of aluminum bars 2 4 are fixed alternately and parallelly between the two mounting plates 5 at equal distances, specifically, the mounting plate 5 can be made of the same material as the aluminum bars 1 3 and the aluminum bars 2 4, and a plurality of oil discharge ports 12 are equidistantly provided at the bottom of the rectangular outer frame 1, so as to discharge the oil droplets collected by the plurality of aluminum bars 1 3 and the aluminum bars 2 4.

[0028] For further information, see Figure 5 and Figure 7The top and bottom ends of the aluminum bar 1 3 are provided with positioning posts 14, and the top and bottom ends of the aluminum bar 2 4 are provided with positioning posts 13. Specifically, the positioning posts 14 and the aluminum bar 1 3 as well as the positioning posts 13 and the aluminum bar 2 4 are integrally formed. In the actual production process, the aluminum bar 1 3 and the aluminum bar 2 4 are both formed by casting. Therefore, the shapes of the positioning posts 1 13 and the positioning posts 2 14 can be taken into consideration when designing the casting mold, and the positioning posts 1 13 and the positioning posts 2 14 can also be welded after the aluminum bar 1 3 and the aluminum bar 2 4 are cast.

[0029] In the present application, mounting holes 11 adapted to the positioning column 1 13 and the positioning column 2 14 are provided on the mounting plate 5. The so-called adaptation means that the positioning column 1 13 and the positioning column 2 14 can be just inserted into the mounting hole 11. Therefore, the size of the mounting hole 11 needs to be adapted to the positioning column 1 13 and the positioning column 2 14, and the number and spacing of the mounting holes 11 also need to be adapted to the positioning column 1 13 and the positioning column 2 14. The positioning column 1 13 and the positioning column 2 14 are inserted into the mounting hole 11 and welded to form a positioning sheet 6.

[0030] Based on this, the present application provides bosses 7 at the top and bottom of the rectangular outer frame 1. Therefore, a slideway is formed on the inner side of the top and the bottom of the rectangular outer frame 1 through the provided bosses 7. A rectangular mounting groove is provided on the left or right side of the rectangular outer frame 1 and an aluminum plate is provided at the mounting groove to cover the mounting groove. The slideway cooperates with the positioning piece 6 to slide the whole consisting of aluminum bar 1 3, aluminum bar 2 4 and mounting plate 5 into the rectangular outer frame 1 through the mounting groove or slide it out from the rectangular outer frame 1, making the entire wind-off-grid installation operation simpler and faster. At the same time, the positioning piece 6 is clamped in the slideway to ensure the reliability of the installation.

[0031] Therefore, the surface of the positioning piece 6 is set to be a smooth spherical surface, the boss 7 is adapted to the shape of the positioning piece 6, and the contact surface between the boss 7 and the positioning piece 6 is set to be a smooth surface.

[0032] In addition, it should be noted that in the present application, after the aluminum strip 1 3 and the aluminum strip 2 4 are installed in the rectangular outer frame 1, the aluminum strip 1 3 and the aluminum strip 2 4 are both located in the middle position of the rectangular outer frame 1. At the same time, the front-to-back dimension of the aluminum strip 2 4 in this embodiment is larger than the front-to-back dimension of the aluminum strip 1 3. Specifically, in this embodiment, the front-to-back dimension of the aluminum strip 2 4 is 22.5 mm, and the front-to-back dimension of the aluminum strip 1 3 is 20.5 mm. After the installation is completed, Figure 6 As shown, both the front and rear ends of the aluminum bar 1 3 are provided with tooth grooves 8. The vertical plane where the tooth grooves 8 at the front ends of the multiple aluminum bars 1 3 are located is rearward compared to the vertical plane where the front ends of the multiple aluminum bars 2 4 are located, and the same is true for the rear ends. This design is more conducive to air intake and noise reduction.

[0033] like Figure 6 and Figure 7As shown, the middle part of the aluminum strip 1 3 is set as a convex arc portion convex to the left and right sides, and a plurality of convex points 1 9 are provided on the front and rear side surfaces of the convex arc portion, and the middle part of the aluminum strip 2 4 is set as a concave arc portion concave inwardly on the left and right sides, and the shape of the concave arc portion is adapted to the shape of the convex arc portion, and a plurality of convex points 2 10 are provided on the deepest surface of the concave arc portion.

[0034] Since the convex point 1 9 and the convex point 2 10 are both convex point-shaped and are integrally formed with the aluminum strip 1 3 or the aluminum strip 2 4, it is particularly important to note that the processing and forming method of the aluminum strip 1 3 and the aluminum strip 2 4 is significantly different from the traditional aluminum profile processing and forming method. In the present application, the aluminum strip 1 3 and the aluminum strip 2 4 are both cast and formed by a forming mold to ensure that the convex point 1 9 and the convex point 2 10 can be integrally formed with the aluminum strip 1 3 or the aluminum strip 2 4.

[0035] Furthermore, the convex points 1 9 and the convex points 2 10 are arranged in a straight line in the vertical direction, and the distance between any two adjacent convex points 1 9 and the distance between any two adjacent convex points 2 10 are the same. In practice, the convex points 1 9 and the convex points 2 10 can be arranged in the vertical direction while keeping the convex points 1 9 and the convex points 2 10 staggered up and down to improve the diversion, noise reduction and silencing effect of the smoke.

[0036] It should be noted that, in the present embodiment, both the protrusion 1 9 and the protrusion 2 10 are set to be hemispherical with smooth surface, and the diameter of the protrusion 1 9 and the protrusion 2 10 are both 0.1 mm. At the same time, the distance between any two adjacent protrusions 1 9 and the distance between any two adjacent protrusions 2 10 can also be 0.1 mm, so as to further improve the diversion, noise reduction and silencing effect of the smoke.

[0037] In this embodiment, the gap between any two adjacent aluminum bars 1 3 and aluminum bars 2 4 forms an S-shaped air duct, and the width of the S-shaped air duct is 1.5 mm. The flue gas flows in the S-shaped air duct and can be diverted and noise reduced multiple times through the convex points 1 9 and the convex points 2 10. After the high-temperature flue gas is cooled, the oil mist condenses and adheres to the outer surfaces of the aluminum bars 1 3 and the aluminum bars 2 4, and flows downward under the action of gravity and gathers at the bottom of the rectangular outer frame 1, and is discharged from the oil discharge port 12.

[0038] It should be noted that, in the present embodiment, both aluminum bar 1 3 and aluminum bar 2 4 have a cavity, the shape of which matches the appearance of aluminum bar 1 3 and aluminum bar 2 4. Adding ribs and adjusting the shape in the cavity can effectively improve its strength and rigidity, enabling it to withstand a larger load while avoiding material waste and reducing the overall weight of aluminum bar 1 3 and aluminum bar 2 4.

[0039] In summary, refer to Figure 7 , Figure 7The direction indicated by the middle arrow is the flow direction of the flue gas. Therefore, it can be seen that during the actual use of the present application, when the flue gas enters for the first time, it first collides with the tooth groove 8, and the incoming flue gas is first separated by the tooth groove 8. The separated flue gas enters the S-shaped air duct formed between the two adjacent aluminum bars 1 3 and 2 4, and then collides and separates again through the convex point 1 9 and the convex point 2 10. With the cooperation of the tooth groove 8, the convex point 1 9 and the convex point 2 10 and the S-shaped air duct, the oil mist is condensed, so that the oil stains slide down from the side walls of the aluminum bars 1 3 and 2 4 and are discharged through the oil drain port 12, and finally discharged. In this process, the flue gas is separated for many times, which has a good noise reduction and silencing effect.

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
