Description

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

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 that can securely fasten an element cover to a housing of an air cleaner and prevent vibration generated between the housing and the element cover.

Generally, automobiles generate power by mixing fuel and air and burning. 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 of the engine, and at the same time, the engine is operated while repeatedly sucking, compressing, As a result, the car gets power.

As described above, a certain amount of air is required to operate the engine, and the supply of such air flows from the outside of the vehicle. That is, air outside the vehicle flows into the air cleaner housing, and is transferred to the intake manifold through the air intake hose connected to the air cleaner housing and supplied to the engine.

That is, the intake manifold is formed so that the air sucked from the outside through the air cleaner can flow out through the filter, and filters out dust and impurities contained in the air through the filter and supplies the purified air to the engine Thereby supplying air necessary for the combustion operation.

Fig. 1 is a view schematically showing such a conventional air cleaner 1. As shown in Fig.

1, the conventional air cleaner 1 includes a body 10 having an air inlet 12 formed at one side thereof, a discharge port 22 coupled to an upper portion of the body 10, And an element 30 interposed between the body part 10 and the cover part 20. [

The air cleaner 1 having the above-described configuration is configured such that air is introduced into the air cleaner 1 through the air inlet 12 formed in the body portion 10 and the inflow air is purified through the element 30 And is then supplied to the engine through an outlet 22 formed in the cover 20. [

When the air cleaner 1 is used for a long period of time, a large amount of impurities are adsorbed on the element 30, and the filtration function can not be properly performed. Therefore, after a predetermined time has elapsed, the element 30 installed in the body part 10 and the cover part 20 should be replaced with a new element to filter the air.

However, since the conventional air cleaner 1 is combined with the bolts of the body 10 and the cover 20, the bolts fixing the four corners of the body 10 and the cover 20 And then the element 30 needs to be replaced, so that the replacement operation is inconvenient and the replacement takes a long time.

In order to solve the above-mentioned conventional problems, the present applicant has filed Korean Patent Application No. 10-2013-0061599, entitled Air cleaner for vehicles. However, in the case of the above-described technique, the air cleaner 1 can be attached and detached in the air cleaner housing by a drawer, so that the air cleaner 1 can be easily and easily replaced.

However, in Korean Patent Publication No. 10-2013-0061599, in order for the element cover to be coupled to the housing, Formed on both sides of the element cover There is a problem that the element cover is coupled to the housing by engaging the restricting projection with the restricting grooves formed on both sides of the cover portion and the body portion but the restricting projection is separated from the restricting groove by the movement of the vehicle.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide an air cleaner for a vehicle which can firmly fasten an element cover to a housing of an air cleaner and prevent vibration generated between the housing and the element cover do.

According to an aspect of the present invention, there is provided an air conditioner, comprising: a housing having an air inlet for introducing air or an air outlet for discharging air; An element inserted or drawn into the housing through a receiving opening formed at one side of the housing; An element cover provided on one side of the housing to prevent the element from being detached from the receiving port; A plurality of first locking members protruding from an upper portion of the element cover so as to have an elastic force, A plurality of first restraint members each having an insertion port protruding from an upper portion of the receiving port so as to insert the engaging jaw and a restricting jaw formed so as to face upward from one end of the insertion port and engaging with the engaging jaw; A plurality of second locking members protruding from one side lower portion of the element cover to have an elastic force and having an elastic latching portion directed downward at an end thereof; A plurality of second restricting members provided at a lower portion of the receiving opening, the elastic restricting portions of the second locking member being engaged with the bottom surface of the second locking member; And a plurality of supporting members formed between the first locking members and protruding from the first locking members and supporting grooves formed between the first locking members to support the supporting pieces to prevent vibration of the element cover relative to one side of the housing. The present invention provides an air cleaner for a vehicle, comprising:
