Claims

[Scope of utility model registration request]

(1) A main body having an inlet and an outlet, a dust ventilation pipe installed inside the main body connected to the outlet, and an interior space installed concentrically with the dust ventilation pipe and spaced inward from its inner wall surface. A centrifugal type that includes a ventilation pipe, an annular partition plate that connects the lower edges of these two tracheas to each other to form a closed-bottom annular dust chamber, and a dust cup that is connected to the lower part of the main body. In air purifiers,
a divider plate is provided between the dust cup and the annular diaphragm, the divider plate forming a flow path from the internal vent tube leading to an outlet of the body and forming a dust sump cavity within the dust cup; A centrifugal air cleaner characterized in that a dust guide pipe is provided that communicates the dust chamber and the dust storage space.

(2) Utility model registration scope In the centrifugal air cleaner according to claim 1, one end of the dust guide tube protrudes into the dust chamber, and the end opening opposes the swirling flow in the dust chamber. The centrifugal air cleaner is further characterized in that the other end of the dust guide tube has an opening facing in a direction opposite to the opening at the one end.

(3) The centrifugal type described in claim 1 of the utility model registration claim'
In the air purifier, there is a gap between the outer peripheral surface of the other end of the dust guide pipe and the edge of the hole of the partition plate through which the dust guide pipe passes, allowing flow from the dust reservoir space to the flow path. A centrifugal air purifier characterized by:
