[Industrial applications]

 The present invention relates to an air cleaner mounted on, for example, a vehicle, and more specifically, an air cleaner that has improved versatility by changing a position of an intake port according to an air intake direction without changing a shape of a case body. Regarding

[0002]

[Prior Art]

 The space available in the engine room of modern automobiles is extremely small due to the installation of various accessories, and there are restrictions on the space for installing the air cleaner. In addition, as a measure to reduce the weight of vehicles, the air cleaner case and cover made of synthetic resin molded bodies have been put into practical use instead of conventional metal press molded bodies. This type of air cleaner made of synthetic resin has flexibility in molding, such as being able to be molded into a shape that corresponds to the engine room.In addition, reinforcing ribs can be integrally molded at locations that require partial strength, so mass productivity is improved. It is also used in passenger car air cleaners because it is also preferable.

[0003]

[Problems to be solved by the device]

 However, with the diversification of automobiles, the engine room is also diversified, and in order to install the air cleaner in the engine room of the automobile, it is necessary to select and install the air cleaner according to the intake direction of air into the air cleaner. In this way, since the entire air cleaner has to be changed only by changing the direction of air intake, the air cleaner tends to be diversified in small quantities. However, the air cleaner made of synthetic resin has a problem that the mold for molding the air cleaner is very expensive and cannot be applied to the air cleaner that is manufactured in a small number.

This invention solves the above problem, and the intake port for air intake is provided in the upper part of the case body and in the front and rear three directions according to the mounting layout of the air cleaner without changing the case body of the air cleaner. The purpose of the present invention is to provide a low cost air cleaner with high mass productivity by making most of the molding dies common by using a versatile air cleaner case body that can select the suction direction from either.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an element inside by assembling an upper case body having an air intake port and a lower case body having an air discharge port in an airtight manner. An air cleaner in which a space for storage is formed, the upper case body and the lower case body are detachable, and an element stored in the space is a filter member formed in a corrugated shape. Is shaped into a hollow rhombus so that the continuous direction of the waves is rhombic, and the upper end plate that covers the upper opening of the hollow end and the air discharge that covers the lower opening and communicates with the air discharge port in an airtight manner. And a bottom end plate having a hole formed therein, wherein the air intake port is formed on one of an upper portion and a side portion of the case body.

[0006]

[Action]

 According to the above configuration, most of the case main body is shared, and the intake port for air intake can be selected from three ways according to the mounting state of the air cleaner on the vehicle. Can be

[0007]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the air cleaner according to the present invention. In the figure, 1 is a case body made of synthetic resin (upper case body), 2 is a filter element, 3 is a base body (lower case body) made of synthetic resin, and the base body 3 and the case body 1 are assembled in an airtight manner. By attaching it, a space for accommodating the filter element 2 is formed inside, and the base body 3 and the case body 1 are detachable.

The case body 1 has an opening 4 on the bottom surface, is composed of four side walls 5 and a ceiling portion 6, and an intake port 7 is integrally formed on the upper surface of the ceiling portion 6 so as to project therefrom. In this embodiment, the suction port 7 is formed on the upper surface of the ceiling portion 6, but it may be provided at the rear portion or front portion shown by the chain double-dashed line 7a. Then, by preparing in advance a plurality of case main bodies 1 each having a suction port formed in the ceiling portion 6, the rear portion or the front portion, it is possible to remove layout restrictions in the engine room as described later. it can.

The filter element 2 includes a diamond-shaped upper end plate 8, a lower end plate 10 having a discharge port 9, a side plate 11 provided between the upper and lower end plates 8 and 10, and a continuous wave direction in the vertical direction. The filter member 12 is formed in a hollow diamond shape so as to be a diamond shape along the outer sides of the end plates 8 and 10, and the perforation reinforcing plate 13 adhered and held along the inside of the filter member 12. The upper and lower end plates 8 and 10 cover the upper surface opening and the lower surface opening of the filter member 12. A packing 9a is provided at the discharge port 9 of the lower end plate 10. The base body 3 includes a discharge pipe 15 provided at a lower portion of the bottom plate 14, a standing wall 16 standing upright from the periphery of the bottom plate 14, and a packing 17 arranged on an inner circumference of the standing wall 16. I have it.

With the above-described structure, the filter element 2 is sorbed on the outer circumference of the discharge pipe 15 protruding to the inner surface of the base body 3 so as to be sealed by the packing 9a attached to the discharge port 9 of the filter element 2. The case body 1 is attached to the base body 3 by means such as a clip not shown so that the lower end of the side wall 5 contacts the packing 17 of the base body 3 and the elasticity of the packing 17 seals the base body 3. When dirty air containing dust collides with the upper surface of the upper end plate 8 of the filter element 2 when sucked from the suction port 7, the air is separated into both sides of the filter element 2 and the side wall 5 of the case body 1 and the filter member 12 are separated from each other. The air is filtered by passing through the filter member 12 through the space between them, becomes clean air, passes through the discharge port 9 of the filter element 2, is discharged from the discharge pipe 15 of the bottom plate 14 of the base body 3, and is supplied to the engine. In this case, the side plate 11 of the filter element 2 is located close to the side wall 5 of the case body 1, but both sides of the rhombus are spaced from the side wall 5, so that the suction port 7 is located at the rear or front. Even if it is replaced with the formed case body, the filter element 2 still fulfills its function sufficiently, and the direction of the intake port for air intake can be arbitrarily selected from among the three directions depending on the mounting condition of the air cleaner on the vehicle. As a result, a highly versatile air cleaner can be obtained.

[0011]

[Effect of the device]

 As described in detail with reference to the embodiments above, in the air cleaner according to the present invention, when the air cleaner is mounted on a vehicle without changing most of the molding die for manufacturing the air cleaner made of synthetic resin, Accordingly, by selecting one of the three directions for the inlet for air intake, a highly versatile air cleaner can be obtained.Since the element is a rhomboidal cube, the element works effectively and the utilization rate is high. Spread and rationalize.
