Description
Technical field
The present invention relates to cleaning appliance, relate in particular to dust catcher, particularly the dirt cup of dust catcher.
Background technology
One Chinese patent application has disclosed a kind of dust catcher No. 200920184866.7; This dust catcher comprises primary cyclone, a plurality of secondary cyclone of arranging side by side each other; Described primary cyclone is positioned at the upper reaches of described secondary cyclone; Described primary cyclone comprises one-level whirlwind bucket, is positioned at the single stage of dust collection chamber of one-level whirlwind bucket below, is arranged on the inner one-level diversion column of described one-level whirlwind bucket; Have a direction and tangent one-level air inlet and the one-level ash hole of bucket inwall on the bucket wall of described one-level whirlwind bucket; Described one-level ash hole is positioned at the below of described one-level diversion column and along the tangential direction setting of air-flow rotation, makes the dust that separates via one-level whirlwind bucket to throw away along the tangential direction of air-flow rotation then to drop into described single stage of dust collection indoor.
The course of work of above-mentioned dust catcher is: after dust-contained airflow gets into one-level whirlwind bucket from one-level air inlet tangential; Dust-contained airflow at the inner chamber of one-level whirlwind bucket along the spiral rotation from up to down of one-level diversion column; When rotating to the one-level ash hole place of below; Cinder can throw away to single stage of dust collection indoorly along with the part air-flow, and the air-flow that has a small amount of thin ash can be through being arranged on the inside that one-level ash hole on the truncated cones shape grid flows into the one-level diversion column, and this air-flow can continue to rise.Because the secondary air inlet of each secondary cyclone all communicates with the inside of one-level diversion column; Air-flow in the one-level diversion column can get in each secondary cyclone uniformly and separate; Thin ash can constantly fall into the secondary dust storage chamber; Thereby, make the dust separation effect of primary cyclone be improved, also guaranteed from the cleanliness factor of the air-flow of this dust catcher discharge.
But; In the above-mentioned dust catcher, because the one-level ash hole is arranged on one-level whirlwind bucket near on the bucket wall of flat board and dull and stereotyped arrange along horizontal direction, so; Cause dust accretions easily on flat board; And the dust that is deposited on the flat board gets into the secondary dust storage chamber by airborne dust and along with the rotation of air-flow from diversion column, so separative efficiency is low.
Summary of the invention
