Dust exhaust device for air cleaner

Abstract

Abstract PURPOSE:To perform high-efficient exhaust of dust in intake air, by a method wherein an air cleaner is disposed adjacently to a high velocity air flow passage, and dust in an air cleaner can be sucked and exhausted by means of a high velocity air flow. CONSTITUTION:An air cleaner 15 well suitable for the engine of a small working vehicle contains a filter element 23 contained in a case in orientation to be inclined based on a case peripheral wall 20, and a C-shaped air passage 35 is formed between the element 23 and the peripheral wall 20. An inlet 36 of the air passage 35 is formed with on inlet wall part 37 formed in the vicinity of a corner part 30 of the peripheral wall 20. A dust receiver 40 is situated to the inner surface of a case front wall part 26, and dust air incoming to the air passage 35 is moved to the corner part 31 side thanks to a centrifugal force, exerted when the direction of an air flow is changed, to collect the dust by means of a dust receiver 40. The dust is exhausted through an exhaust port 42 by dint of a high velocity air flow passing through a cold air passage 45.
