Description

[0001] The present invention relates to an air cleaner for vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner for a vehicle, and more particularly, to an air cleaner for a vehicle, which can be assembled with a drawer in an element provided inside an air cleaner and can always insert the element only in a correct direction.

An internal combustion engine used as an automobile power source sucks outside air and mixes it with fuel and burns it to form power. That is, the fuel stored in the fuel tank of the automobile passes through various fuel supply devices, is mixed with the air introduced from the outside and is injected into the cylinder inside the engine, and at the same time, the piston reciprocates according to the suction, compression, explosion, And the vehicle is powered.

As described above, a certain amount of air is required to operate the engine. However, when the outside air is directly sucked and used, the pollution material contained in the air may lower the combustion efficiency of the engine. Therefore, the air used for combustion of the vehicle engine needs to be foreign air as much as possible.

Therefore, the air supplied to the vehicle engine can be separated from the pollutants while passing through the air cleaner. That is, the sucked air flows into the interior of the air cleaner housing, the pollutants are removed by the filter member, and then is transferred to the intake manifold through the air intake hose connected to the air cleaner housing and supplied to the engine. The intake manifold is formed to allow air sucked from the outside through the air cleaner to pass through the filter to the opposite side. The dust and impurities contained in the air are filtered through the filter, and the purified air is supplied to the engine, To supply the necessary air. The general structure of such an air cleaner has been disclosed in Korean Patent Laid-Open No. 10-2013-0061599 (published on Mar. 11, 2013).

In recent years, a drawer-type detachable structure has been proposed so that the maintenance of the element can be more easily performed. The related art is disclosed in Korean Patent No. 10-1400841 (registered on April 22, 2014).

However, since the air cleaner having the drawer-type detachable structure has the directionality of the filter, the performance of the filter may not be exhibited properly when the filter is inserted in the wrong direction. Also, if the sealing portion is not completely sealed at the mounting position after the element is slidably mounted, the unfiltered contaminated air may enter the engine of the vehicle through the filter. If the element is inserted in the wrong direction by an untrained person, there is also a concern that the performance of the filter will be deteriorated as well as a vehicle failure due to engine inflow of contaminated air due to lack of sealing.

Also, a box-like shape may be formed on the upper side of the first body so that a receiving space 119, into which an element 130 to be described later, can be slidably inserted, can be formed by coupling with the second body 120. In addition, the upper portion of the first body 110 may be opened, and the air inlet 112 may be eccentrically spaced from the upper opening by a predetermined distance.

In addition, the first body 110 may have a seating jaw extending laterally along an outer rim of the opened upper end, and a support rim may be formed along the rim on both sides in the width direction so as to face each other. However, the present invention is not limited thereto, and any structure can be used as long as the second body 120 is capable of complementary coupling.

2, a guide rail 114 for guiding a sliding movement path of the element 130 may be integrally formed on both side walls of the receiving space portion 119. As shown in FIG. At this time, a hook 115 is formed at the end of the guide rail 114 so that the first end 133d of the shaft 133a of the element 130 to be described later can be seated.

The second body 120 is coupled to the opened upper side of the first body 110 and may be formed in a box shape having a receiving space therein as in the first body 110. The second body 120 may form an opening through which a surface facing the first body 110 is opened and may include an air outlet 122 for discharging the air introduced through the air inlet 112 to the outside, May be formed.

The lower end of the second body 120 may be provided with a complementary jaw extending in the lateral direction along the outer edge so as to be seated in the seating jaw formed in the first body 110 .

At this time, when the first body 110 and the second body 120 are in contact with each other, the air is filtered at one side of the portion where the seating jaws of the first body 110 and the second body 120 are in contact with each other, A storage space 119 in which the element 130 is slidably inserted or drawn out by a drawer can be formed. The storage space portion 119 is formed in a shape corresponding to the element 130 and the element 130 is inserted or withdrawn in a directional manner inside the first body 110 and the second body 120 through the receiving opening, May be formed to be drawn out.

As shown in FIG. 3, the element 130 has various types such as a dry type using a filter or synthetic fiber, a wet type using an engine or water, and a doubled type in which a wet type and a dry type are integrated, The air introduced into the air cleaner 100 by using the dry type filter is filtered through the element 130 by the negative pressure of the engine and can be formed into a rectangular shape.

The filter member 131 is formed on the outer circumferential surface of the filter member 131 so as to surround the outer circumferential surface of the filter member 131. The filter member 131 includes a filter member 131 for filtering impurities contained in air, A sealing frame 132 for preventing the filter member 131 from being deformed by the flow pressure of the air and a sealing frame 132 coupled to the sealing frame 132 to prevent the element 130 from contacting the second body 120. [ And a lifting unit 133 that can be brought into close contact with the upper surface of the receiving portion of the receiving unit. 2 and 3, the element 130 is inserted at a predetermined angle with respect to the bottom surface so that the first body 110 is disposed on the lower side with respect to the element 130, The second body 120 may be disposed on the upper side so that an air flow can be formed from below to above.

The filter member 131 is made of a synthetic fiber material and can be formed to have a sufficient filtration area by stacking the filter member 131 in multiple stages. As shown in the figure, the filter member 131 may be formed by folding the filter member 131 a plurality of times so as to form a corrugation. The filter member 131 may contact the air through a wide area as much as possible to filter contaminants contained in the inhaled air .

The sealing frame 132 is formed of a rectangular frame shaped to surround the outer circumferential surface of the filter member 131, and the flange can be formed to extend and project laterally.

4, a plurality of fixing brackets 134 are formed on one side of the flange so as to protrude downward, so that a lift unit 133, which will be described later, (Not shown). At this time, a cam member 133b to be described later may be formed at the position of the fixing bracket 134. [

The plurality of fixing brackets 134 are integrally fixedly coupled to the flange at one end and are rotatably fitted to the elevating unit 133 at the other end. The plurality of fixing brackets 134 Are formed as a pair, and a plurality of the fixing brackets 134 are formed along the longitudinal direction of the flange.

The elevating unit 133 may include a shaft 133a, a cam member 133b, and a handle 133c.

The shaft 133a is formed in a shaft shape and a knob 133c can be integrally formed at one end so that the user can grasp and rotate the shaft 133a. However, it is not limited thereto, and if necessary, the handle 133c may be formed as a separate member. For example, the handle 133c may be provided with a knob member in the form of a disk.

In addition, a plurality of eccentric cams 133b may be spaced apart from each other on a shaft of the shaft 133a at regular intervals. The cam member 133b is formed to have a diameter wider than the diameter of the shaft 133a and one side of the cam member 133b is extended in an egg shape. When the user holds the handle 133c of the lifting unit 133 The protruded portion of the cam member 133b is supported by the support protrusions formed on the first body 110 while being directed downwardly so that the height of the element 130 can be adjusted.

That is, when the lifting unit 133 is inserted into the housing space 119 formed in the initial body 110 and the initial body 120 in a state of being coupled to the lower portion of the flange of the element 130, And the extended protruding portion of the member 133b is inserted in a rotated state so as to face the horizontal direction. After the element 130 is completely inserted, the knob 133c is rotated so that the extended and protruded portion of the cam member 133b is rotated downward. Through the pivoting operation, the element 130 can be lifted upward by the support jaws formed on the first body 110 and can be brought into close contact with the upper side of the storage space 119 of the second body 120. However, the present invention is not limited thereto, but may be configured to be in close contact with the lower side of the storage space 119 of the first body 110. It can vary as much as you like, depending on the design.

Therefore, since the element 130 is in close contact with the first body 110 and / or the second body 120 of the air cleaner 100, the flow pressure flowing into the air cleaner 100 is not shaken, .

In addition, since the element 130 is in close contact with the first body 110 and the second body 120, it is possible to prevent air from leaking, thereby preventing leakage of sound.

In addition, the element 130 can easily and easily be brought into close contact with the first body 110 and the second body 120 by a simple operation of rotating the lifting unit 133.

4 and 6, the lifting unit 133 includes a first end 133d of the shaft 133a on the insertion end side of the element 130, The second end portion 133e formed on the other side of the sealing portion 133d may be spaced apart from the sealing frame 132 at different distances.

3 and 4, the first end portion 133d on the insertion end side may be spaced apart from the insertion end portion of the sealing frame 132 by a first distance d1, and the second end portion 133e May be disposed at a second distance from the exposed end 132b of the sealing frame 132 at all times. At this time, the first distance d1 may be formed larger than the second distance. Also, according to the present embodiment, the second distance may be less than 5 mm, and preferably, the second end 133e and the exposed end 132b may be disposed on the same plane.

On the other hand, a latching protrusion 115 on which the first end portion 133d of the shaft 133a is seated may be provided on the inner side of the accommodation space 119. The stopper 115 is in surface contact with the end of the shaft 133a of the inserted element 130 to guide the insertion position of the element 130. When the element 130 is correctly inserted, The element 130 can be seated in the interior of the accommodation space 119 without projecting through the complementary seating engagement of the engagement protrusion 133d and the engagement protrusion 115. [ On the other hand, when the element 130 is inserted in the abnormal direction, for example, in the opposite direction, the second end 133e faces the stopping jaw 115. In this case, The element 130 is inserted less than the normal direction and is not rotated to the closed position even if the end is exposed to the outside of the opening and the cover member 140 is rotated and closed to the closed position So that the user can visually confirm that the element 130 is erroneously inserted.

In this case, too, the engaging jaw can not interfere with the shaft 133a, and interferes with the sealing frame 132 protruding from the circumferential surface, Since the element 130 protrudes without being inserted, it can be confirmed that the user has visually inserted the element 130 improperly.

Meanwhile, a cover member 140 may be provided on an outer surface of the housing space 119 into which the element 130 is inserted.

2 to 5, the cover member 140 is rotatably formed on the second body 120 so that the element 130 inserted into the storage space portion 119 is exposed to the outside The opening of the storage space portion 119 can be sealed and closed.

According to the present embodiment, the cover member 140 may include a pressing member 141 and a locking unit 142, as shown in Fig.

The pressing member 141 can press the element 130 at the closed position so as to press the element 130 so as not to swing inside the storage space portion 119. [ The pressing member 141 can be brought into close contact with the end portion of the element 130. According to this embodiment, the pressing member 141 and the sealing frame 132 of the element 130 can be in surface contact with each other.

The locking unit 142 may be provided such that the cover member 140 can be selectively hooked to the first body 110 as shown. For example, the locking unit 142 is fixed to the cover member 140 at one side by using an elastic piece or the like, while the other side is hooked to the hook formed at the corresponding position of the first body 110 side , And can be hooked and fixed to the engaging portion while elastically deforming in conjunction with the closing operation of the cover member (140). However, the present invention is not limited thereto, and any structure can be selected as long as the cover member 140 can be selectively opened and closed.

In addition, the cover member 140 may have a flat surface corresponding to the element 130. This is for surface contact with the element 130 when the element 130 is normally inserted. As a result, the abnormally inserted element 130 protrudes outside the opening of the accommodating space portion 119, so that the cover member 140 can not be blocked by the projected element 130.

Meanwhile, in the air cleaner 100 for a vehicle according to an embodiment of the present invention, the first body 110 and the second body 120 may be fixed by a method such as thermal fusion without separate fastening means. However, the present invention is not limited to this, but it is also possible to constitute a complementary shape and fix it by using a plurality of fastening elements, for example, a "C" shaped clamp or the like.

Accordingly, the air cleaner for a vehicle according to an embodiment of the present invention can easily and easily be combined with the first body 110 and the second body 120, minimizes the generation of vibration sound, Replacement is easy.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
