Abstract

A filter assembly for a vacuum cleaner of the type having a motor, a housing enclosing the motor, a fan driven by the motor for producing a vacuum, and a canister removably attached to the front end of the housing and having an intake nozzle for reception of foreign matter, liquid and air drawn into the canister in response to the vacuum developed by the fan. The filter assembly includes an air permeable filter member disposed within a framework. The filter member includes a front wall. A hollow member extends axially from the front wall towards the open end of the canister. The hollow member is readily graspable by a user when the canister is removed. The filter assembly further includes a filter housing disposed within the canister and having a front wall. A member axially extends from the front wall towards the open end of the canister and is accessible by the user when the filter is removed from the filter housing.

Claims

1. A filter housing and filter assembly for a vacuum cleaner, the vacuum cleaner including a motor, a housing enclosing the motor, a fan driven by the motor for producing a vacuum and a canister removably attached to the front end of the housing and having an intake nozzle for reception of foreign matter, liquid and air drawn into the canister in response to the vacuum developed by the fan, said assembly comprising:

means for filtering foreign matter from the air entering the canister;

means for housing said filtering means within the canister;

first grasping means extending from said filtering means towards a first open end of said canister and readily graspable by a user when the canister is removed from the front end of the vacuum cleaner housing to move the filtering means relative to the housing means towards the first open end of the canister; and

second grasping means extending from said housing means towards the first open end of

said canister and accessible by a user when the filtering means is removed from said housing means.

2. An assembly as set forth in claim 1, wherein:

said first grasping means comprises a generally hollow axially extending member; and

said filtering means comprises an integral framework formed by a plurality of ribs and and air permeable filter member disposed within said framework, said filter member having a front wall, said hollow member extending from said front wall towards said open end of the canister.

3. An assembly as set forth in claim 2 wherein:

said front wall of said filter member includes means defining a slot in axial alignment with said hollow member;

said housing means comprises a filter housing disposed within the canister and having a front wall; and

said second grasping means comprises a member extending axially from said front wall of said filter housing towards said open end of said canister, said member extending through the slot formed in the front wall of the said filter member and being telescopically received within the hollow member.
