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
Chinese patent application has disclosed a kind of dust catcher No. 200920184866.7, this dust catcher comprises primary cyclone, a plurality of secondary cyclones of arranging side by side each other, described primary cyclone is positioned at the upstream of described secondary cyclone, described primary cyclone comprises one-level whirlwind bucket, be positioned at the single stage of dust collection chamber of one-level whirlwind bucket below, be arranged on the one-level diversion column of described one-level whirlwind bucket inside, have a direction one-level air inlet and an one-level ash hole tangent with the 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 tangentially enters one-level whirlwind bucket from the one-level air inlet, 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 rotation during to the one-level ash hole place of below, cinder can throw away to single stage of dust collection indoor along with the part air-flow, the air-flow that has a small amount of thin ash can be by being arranged on the inside of the one-level ash hole inflow one-level diversion column on the truncated cones shape grid, 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 enter uniformly in each secondary cyclone 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 the close dull and stereotyped bucket wall of one-level whirlwind bucket and flat board is arranged along horizontal direction, so, cause dust accretions easily on flat board, and the dust that is deposited on the flat board is entered secondary dust storage chamber along with the rotation of air-flow from diversion column by airborne dust, so separative efficiency is low.
