Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vertical air cleaner device for an engine.

[0002]

[Prior art]

 As a conventional art of a vertical air cleaner device for an engine, there is one shown in FIG. This is because the cylindrical element 102 is vertically accommodated in the air cleaner case 101, and the air guide tube 103 is fitted around the upper end portion of the element 102, and the air guide tube formed around the air guide tube 103. The space 104 is exposed to the outside air introduction port 105 formed in the air cleaner case 101, a lower opening-shaped cover 106 is provided outside the outside air introduction port 105, and the outside air swirling guide is provided from the air guide tube 103 into the air guide space 104. The plate 107 is projected.

With such a configuration, the outside air introduced from the outside air introduction port 105 is guided by the outside air swirling guide plate 107 and swung in the air cleaner case 101, and among the dust contained in the outside air, high-weight sand dust is included. Etc. can be separated and removed in advance by centrifugal force, and the dust removal performance by the element 102 can be improved.

By the way, in the above-mentioned conventional technique, the inside of the cover 106 is formed only as a ventilation space.

[0005]

[Problems to be solved by the device]

 The above conventional technique has the following problems. Since the inside of the cover 106 is formed only as a ventilation space, the outside air 108 introduced from the outside air inlet 105 is introduced along a direction substantially orthogonal to the outside air inlet 105 and guided by the outside air swirl guide plate 107. Only by itself, the swirl distance of the outside air in the air cleaner case 101 cannot be made sufficiently long. For this reason, heavy dust cannot be sufficiently separated and removed by centrifugal force.

Since the swirl distance of the outside air 108 in the air cleaner case 101 cannot be made sufficiently long, most of the outside air is sucked in from the outside air introduction port 105 side portion of the element 102, and the outside air 108 is sucked in from the opposite side. hard. Therefore, the element 102 is locally clogged and the life of the element 102 is short.

An object of the present invention is to allow a long swirl distance of outside air in an air cleaner case.

[0008]

[Means for Solving the Problems]

 In the present invention, as illustrated in FIG. 1, a cylindrical element 2 is vertically housed in an air cleaner case 1, and a baffle tube 3 is externally fitted to a portion of the element 2 near the upper end thereof. The air introducing space 5 formed in the air cleaner case 1 is exposed to the air guiding space 4 formed around the cylinder 3, and a lower opening-shaped cover 6 is provided on the outside of the outside air introducing port 5 to provide the air guiding space. The engine vertical air cleaner device in which the outside air swirl guide plate 7 is projected from the air duct 3 into the air guide space 4 is characterized by the following.

That is, as illustrated in FIG. 1B, an outside air deflecting plate 8 is provided inside the cover 6, and outside air 9 introduced from the outside air introducing port 5 is swirled by the outside air swirling guide plate 7. It is characterized in that the outside air deflecting plate 8 is deflected in the inward direction 10.

[0010]

[Operation and effect of the device]

 The outside air deflecting plate 8 is provided inside the cover 6, and the outside air introduced from the outside air introducing port 5 is deflected by the outside air deflecting plate 8 in the swirling guide direction of the outside air swirling guiding plate 7. The outside air 9 introduced from 5 is introduced along the swirl guide direction 10 of the outside air swirl guide plate 7, and the swirl distance of the outside air 9 guided by the outside air swirl guide plate 7 becomes long. Therefore, the heavy dust and the like can be sufficiently separated and removed by the centrifugal force.

Since the outside air 9 is sufficiently swirled in the air cleaner case 1, the outside air 9 is sucked from the entire circumference of the element 2. Therefore, the element 2 is evenly clogged, and the life of the element 2 is long.

FIG. 1C is an exploded perspective view of the air cleaner device, which is a sectional view taken along line -B.

The air cleaner device of this embodiment is as follows. Reference numeral 1 in FIG. 1 indicates an air cleaner case, which is composed of a case body 19 made of resin and a lower case 20. The case body 19 is a cylindrical body having an upper wall 23, and the lower case 20 is in the shape of a saucer that is fitted onto the clean air introduction pipe 24. A horizontal step portion 15 is formed on the upper portion of the purified air introduction pipe 24, and the bolt 11 is erected from the purified air introduction pipe 24. The case body 19 and the lower case 20 can be fitted from above and below, and the case body 19 can be fixed to the lower case 20 by the fastening force of the bolt 11 and the wing nut 12 that penetrate the upper wall 23 of the case body 19. Has become.

A cylindrical element 2 is housed vertically in an air cleaner case 1. The element 2 comprises a cylindrical corrugated plate-like filter 13 and annular shape-retaining plates 14 fixed above and below the filter 13. An annular gasket 16 is interposed between each of the upper and lower shape-retaining plates 14 and the upper wall 9 of the case main body 7 and the horizontal step portion 15 of the clean air introduction pipe 10, and the bolt 11 and the wing nut 12 are provided. The element 2 is fixed in the air cleaner case 1 by the fastening force with the air cleaner chamber 1 in the element 2, and the air purification chamber 17 in the element 2 is communicated with the air introduction pipe 24.

The air guide tube 3 is fitted onto the upper end portion of the element 2. The air guide tube 3 covers approximately 40% of the effective ventilation area of the filter 13. The air guide space 3 formed around the air guide tube 3 faces the outside air introduction port 5 formed in the upper part of the peripheral wall of the case body 7. A dustproof net 18 is attached to the outside air inlet 5. The dust net 18 is integrally formed with the case main body 7 by embedding the peripheral portion thereof in the peripheral portion of the outside air inlet 5. A cover 6 whose lower side is opened is provided outside the outside air inlet 5. A fitting groove 21 is provided in a U shape along the upper and left and right edges of the outside air introduction port 5, and a fitting projection 22 for fitting with this is provided on the cover 6, and a fitting projection 21 fitting into the fitting groove 21 is provided. The cover 6 is detachably attached to the case body 19 by press fitting into the case 22.

A plurality of outside air swirl guide plates 7 are projected from the lower part of the air guide tube 3 into the air guide space 4. Therefore, the outside air 9 introduced from the outside air introduction port 5 is guided by the outside air swirling guide plate 7 and swung in the air cleaner case 1, and among the dust contained in the outside air 9, high-weight sand dust or the like is separated in advance by centrifugal force. It can be removed.
