Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to an air cleaner, and more particularly to an air cleaner having improved handleability when replacing a filter element.

<Prior art> As is well known, low resistance and light weight are recently demanded for air cleaners mounted on vehicles. To reduce the weight, measures such as making the air cleaner case made of synthetic resin are proposed. Has been done.

On the other hand, for lowering resistance, for example,
As disclosed in Japanese Patent Publication No. 5, a so-called tubular air cleaner has been proposed.

In this type of tubular air cleaner, it is said that air passes through the filter element from one side to the other without turning inside the air cleaner, thereby lowering the resistance.

By the way, in this type of tubular air cleaner, if the total length of the filter element is increased when the filtration area of the filter element is increased, there is a technical problem described below.

<Problems to be solved by the invention> That is, if the length of the filter element is increased, the air cleaner case becomes elongated as well,
With such a long case, the filter element becomes clogged with the passage of time, and when clogged, the filter element needs to be replaced.

However, if the air cleaner case is long,
There is a problem that it is difficult to take out the filter element inside.

In this case, it is conceivable to discard the case together with the filter element stored, but in such means, the air cleaner is fixed to the intake system side of the engine such as the vehicle body or carburetor, so the fixed part is not attached or removed. Not only that, it is troublesome and the economic loss is large.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide an air cleaner that allows easy and economical replacement of a filter element.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides an air cleaner including a case having air inlets and outlets formed at both axial ends thereof, and a filter element housed in the case. The case includes a case body formed in an elongated tubular shape and a cover attached to one end of the case body, and the case body is divided into first and second cases with a surface oblique to the axis thereof. It is characterized by having.

You may comprise so that the mounting surface of the said case main body and a cover may incline at the angle different from the division part of the said case main body.

<Operation> According to the air cleaner having the above configuration, since the case body is composed of the first and second cases divided by the obliquely intersecting surface, one of the cases located between the cover and the one case is formed. By removing the part, the filter element can be replaced or discarded together with a part of the removed case.

<< Embodiment >> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an air cleaner according to the present invention.

The air cleaner shown in the figure has a case 10 and a cover 12.
And a filter element 14.

The case 10 is formed in an elongated rectangular tube shape, and is composed of a first case 10a and a second case 10b which are divided by a plane oblique to the axis at an angle α, and the first and The second cases 10a and 10b are airtightly coupled by a plurality of buckles 16 with a gasket interposed on the joint surface.

An air intake port 10c is formed at one end of the first case 10a, and the first case 10a is fixed to the vehicle body side (not shown).

The cover 12 is attached to the rear end of the second case 10b, and has an outlet 12a for clean air provided at one end.The outlet 12a is fixed to the intake system side of the engine such as a carburetor (not shown). It

The filter element 14 is composed of an elongated filter material 14a bent in a bellows shape and a frame body 14b supporting the filter material 14a. The filter element 14 is provided with a gasket on the side surface of the frame body 14b. It is mounted between the case 10b and the cover 12, and is sandwiched by mounting the buckle 18 between the case 10b and the cover 12.

With the air cleaner configured as described above, when the filter element 14 becomes clogged, the buckles 16, 18
If removed, the second case 10d can be separated without removing the first case 10a fixed to the vehicle body side and the cover 12 fixed to the carburetor, etc., whereby the filter element 14 can be easily If you take it out, attach a new filter element and attach the buckles 16 and 18, the replacement is completed.

In this case, the frame 14a of the filter element 14 and the second case 10b may be fixed in advance, and the filter element 14 may be discarded together with the second case 10b at the time of replacement. Also has less economic loss than if the entire air cleaner were to be scrapped.

FIG. 2 shows a second embodiment of the air cleaner according to the present invention, and only the characteristic points will be described below.

In this embodiment, the joint surface between the second case 10b and the cover 12 is joined to each other at a surface oblique to the axis at an angle β.

The oblique angle β is in the opposite direction to the oblique angle α between the first case 10a and the second case 10b, and with such a configuration, the tip portion of the filter medium 14a of the filter element 14 is also the same. It will cross the axis at an angle β,
When removing the filter element 14, the second case 10
If b is moved upward along the joint surface of the bar 12, the filter medium 1
Since the tip of 4a is not caught by the first case 10a, the filter element 14 can be replaced more easily.

FIG. 3 shows a modified example of the embodiment shown in FIG. 2, and since the first case 10a is used as it is in the air cleaner of the present invention, for example, the resonator 20 is provided on the side surface thereof.
By providing the, the economical loss can be significantly reduced as compared with the case where the entire air cleaner is discarded.

<Effect of Device> As described in the above embodiments, according to the air cleaner of the present invention, when the filter element is housed in the elongated cylindrical case to reduce the intake resistance, the case is used as a shaft. By dividing the filter element at an obliquely intersecting surface, it becomes easy to replace the filter element when it is clogged, and at the same time, economical loss is reduced even if the filter element is discarded together with the case.
