Air cleaner with noise reduction {Air cleaner with resonator}
[11] The present invention relates to an air cleaner for noise reduction, and more particularly, by installing a soundproof member inside the air cleaner to remove intake air generated in the process of being sucked into the vehicle and to smoothly flow the introduced air. It is invented to improve the merchandise.
[12] In general, the element 40 is installed between the engine mounted on the vehicle and the air duct, as shown in FIG. 1, by the housing 30 formed by combining the air cleaner housing case 10 and the cover 20.
[13] The outside air introduced into the accommodating part 30 through the air duct is supplied to the engine in a state in which foreign substances such as dust and the like are removed by the element 40.
[14] In addition, the element 40 may also perform a role of removing dust in the air sucked into the engine and at the same time reducing the intake sound.
[15] The element 40 embedded in the air cleaner may be wet when the element is difficult to be replaced mainly due to dryness using paper or fiber, and an installation place or a service problem.
[16] The conventional air cleaner configured as described above has a problem in removing the intake sound generated during the flow of air, but only to filter the air introduced by the element installed as an accommodation part.
[17] It is an object of the present invention to provide an air cleaner for noise reduction that allows air that has passed through the element to pass through a soundproof member having a perforated groove passing through the body to remove intake sound.
[18] Another object of the present invention, by installing a soundproof member having a shape extending from the bottom of the body, the air cleaner for noise reduction to improve the performance of the vehicle to more smoothly supply the air passing through the soundproof member to the engine, etc. To provide.
[1] 1 is a cross-sectional view showing the inside of a conventional air cleaner.
[2] Figure 2 is a cross-sectional view showing the present inventors air cleaner for noise reduction.
[3] Figure 3 is an enlarged cross-sectional view of a part of the present inventors air cleaner for noise reduction.

[6] 21-fixing groove 30-storage
[7] 40-Element 50-Soundproof Member
[8] 51-Passing groove 52-Fixed surface

[10] 70-Gasket 100-Air Cleaner
[19] The object of the present invention, the dust in the outside air introduced through the air duct to the housing 30 formed by coupling the housing case 10 and the cover 20 between the engine and the air duct mounted on the vehicle In the installed configuration, the element 40 for removing foreign matters such as the supply to the engine;
[20] Passing groove 51 is perforated by the body portion, the upper surface is bent and the fixed surface 52 is provided by the fixing member 60 is composed of a soundproof member 50 formed to be in close contact with the inside of the cover 20 do.
[21] Therefore, the noise reduction air cleaner of the present invention can improve the merchandise and convenience by removing the noise generated in the intake air from the soundproof member 50.
[22] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[23] Figure 2 is a cross-sectional view showing the noise reduction air cleaner of the present invention, Figure 3 is an enlarged cross-sectional view of a portion of the noise reduction air cleaner of the present invention.
[24] That is, as shown in FIG. 2, the air cleaner 100 including the housing case 10 and the cover 20 and having the housing 30 therein is provided.
[25] An element 40 is installed in the housing 30 of the air cleaner 100 so that external air flowing into the housing 30 is removed from the engine by the element 40. To be supplied.
[26] In addition, since the element 40 has a cylindrical shape and has an empty space therein, the soundproof member 50 is inserted into the inside.
[27] The soundproof member 50 is tapered from the bottom to the upper to have a large inner diameter, the upper portion is formed bent fixing surface 52 and the fixing surface 52 has the same number of through holes as the fixing member 60 53 is provided.
[28] Therefore, as shown in FIG. 3, the fixing grooves 21 are provided in the cover 20, and the fixing surface 52 formed on the soundproofing member 50 is in close contact with the inside of the cover 20. The member 60 is to fix the soundproof member 50 and the cover 20.
[29] In addition, the gasket 70 is inserted between the cover 20 and the soundproof member 50 to seal the coupling portion and to prevent damage to the soundproof member 50.
[30] That is, the fixing member 60 is coupled to the fixing groove 21 formed inside the cover 20 via the through hole 53 and the gasket 70 of the soundproof member 50.
[31] In addition, a rectangular passage groove 51 is perforated in the body of the soundproof member 50, and injection molding is performed to improve productivity by producing the soundproof member 50.
[32] Therefore, the through groove 51 formed in the body of the sound insulation member 50 occupies half of the surface area of the sound insulation member 50, so that the filtered air can be smoothly sent to the engine.
[33] Therefore, the air introduced from the outside is filtered through the element 40 and then passes through the through groove 51 of the soundproof member 50 to minimize the air resistance generated during intake by using a resonance action to remove the intake sound It is.
[34] According to the configuration of the present invention as described above, when the air passing through the element passes through the soundproof member perforated through the passage groove to the body portion to cause a resonance action to remove the intake noise, the vehicle noise to remove the performance of the vehicle And marketability.
[35] In addition, the body of the soundproof member has a shape that extends from the bottom to the top, so that the air passing through the soundproof member more smoothly supplied to the engine, etc. to improve the vehicle performance and convenience.
[36] Therefore, it is a very useful invention that can improve the reliability and commerciality of the product.
