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. An outside air introduction port 105 formed in the air cleaner case 101 is exposed to the space 104, and an outside air swirling guide plate 106 is projected from the air guide tube 103 into the air guide space 104.

According to such a configuration, the outside air introduced from the outside air introduction port 105 is guided by the outside air swirling guide plate 106 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 air guide tube 103 is adhered to the upper end portion of the element 102, and 40% of the effective ventilation area of the element 102 is covered with the air guide tube 103.

[0005]

[Problems to be solved by the device]

 In the above prior art, since the baffle tube 103 is adhered to the upper end portion of the element 102 and 40% of the effective ventilation area of the element 102 is covered with the baffle tube 103, when the remaining 60% is clogged. The element 102 must be replaced with. Therefore, the life of the element 102 is relatively short.

[0006] The present invention has as its problem the possibility of prolonging the life of the element.

[0007]

[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 an upper end portion of the element 2, An outside air introduction port 5 formed in the air cleaner case 1 is exposed to an air guide space 4 formed around the tube 3, and an outside air swirling plan inner plate 6 is introduced from the air guide tube 3 into the air guide space 4. The vertical air cleaner device for the engine that is projected is characterized by the following.

That is, the upper and lower end portions of the element 2 have the same structure, and the baffle tube 3 can be detachably fitted to either the upper or lower side of the element 2.

[0009]

[Operation and effect of the device]

 Since the upper and lower end portions of the element 2 have the same structure and the air guide tube 3 can be detachably fitted to either the upper or lower side of the element 2, after the lower end portion of the element 2 is clogged. With the element 2, the element 2 can be turned upside down to remove dust in the non-clogging portion. Therefore, the entire area of the element 2 can be effectively used for dust removal, and the life of the element 2 can be extended.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a view for explaining a vertical air cleaner device for an engine according to an embodiment of the present invention. FIG. 1 (A) is a vertical sectional front view of the air cleaner device, and FIG. 1 (B) is an exploded perspective view of the air cleaner device. is there.

The air cleaner device of this embodiment is as follows. Reference numeral 1 in FIG. 1 denotes an air cleaner case, which comprises a case body 7 and a lower case 8. The case body 7 is a cylindrical body having an upper wall 9, and the lower case 8 is in the shape of a pan that is fitted onto the clean air introduction pipe 10. A horizontal portion 15 is formed at the upper end of the purified air introduction pipe 10, and a bolt 11 is erected from inside the purified air introduction pipe 10. The case body 7 and the lower case 8 can be fitted from above and below, and the case body 7 can be fixed to the lower case 8 by the fastening force between the bolt 11 and the wing nut 12 which penetrate the upper wall 9 of the case body 7. It is like this.

A cylindrical element 2 is housed vertically in an air cleaner case 1. The element 2 comprises a cylindrical corrugated plate-shaped 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 body 7 and the horizontal portion 15 of the air-purifying pipe 10, and the bolt 11 and the wing nut 12 are connected to each other. The element 2 is fixed in the air cleaner case 1 by the fastening force, and the air purification chamber 17 in the element 2 is communicated with the air introduction pipe 10.

The air guide tube 3 is fitted on the upper end portion of the element 2. The air guide tube 3 covers about 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 opened in the upper part of the peripheral wall of the case body 7. A dust-proof net 18 is attached to the outside air inlet 5, and the outside thereof is covered with a cover 19 whose lower side is opened. A plurality of outside air swirl guide plates 6 are projected from the lower part of the air guide tube 3 into the air guide space 4. As a result, the outside air introduced from the outside air introduction port 5 is guided by the outside air swirl guide plate 6 and swirled in the air cleaner case 1, and among the dust contained in the outside air, high-weight sand dust or the like is separated in advance by centrifugal force. It can be removed.

In this air cleaner device, the following measures are taken in order to extend the life of the element 2. The upper and lower shape-retaining plates 14 have the same shape, and the upper and lower gaskets 16 have the same shape, so that the upper and lower end portions of the element 2 have the same structure. The baffle tube 3 is press-fitted and attached to the upper end portion of the element 2 so that the baffle tube 3 can be attached to and detached from either the upper side or the lower side of the element 2. For this reason, after the lower end portion of the element 2 is clogged, the element 2 can be turned upside down to remove dust in the non-clogging portion.
