Abstract

A vacuum cleaner with a self-cleaning filter and a sweeper stand that also functions as an electric dustpan when the vacuum is seated within the sweeper stand is provided. The vacuum includes a housing having an air inlet at one end of the housing and a handle at the other end of the housing. An air passageway includes a deflector to direct dirt into a dirt collection tray which is pivotably mounted to the housing. A filter mounted on the motor divider wall and a filter cleaning arch mounted on the dirt collection tray so that the filter cleaning arch strikes the filter to dislodge dirt collected on the filter as the dirt collection tray pivots open. The sweeper stand includes a housing for receiving the hand vacuum, an opening for directing dirt laden air into an air inlet of the hand vacuum. Power switches to actuate the hand vacuum when the hand vacuum is seated in the sweeper stand are provided.

Claims

1. A vacuum cleaner comprising:

an elongated housing defined by an upper wall, a lower wall and two opposed side walls with a portion of the lower wall defining a dirt collection tray, and an air inlet at one end and a hand grip at the other end;

a motor compartment defined within the housing including a vacuum motor positioned therein;

the dirt collection tray is hingedly connected to a portion of the lower wall of the housing;

an inlet air passageway defined by the upper wall and intermediate inner wall;

a pleated filter mounted in the housing above the pivotable collection tray; and

a filter cleaning arch mounted on the dirt collection tray;

wherein upon opening the dirt collection tray, the filter cleaning arch strikes the pleats of the pleated filter to dislodge dirt collected on the filter as the dirt collected in the dirt collection tray is emptied.

2. The vacuum cleaner of claim 1, wherein the inlet air passageway includes a deflector that extends downward from the upper housing at the end of the passageway to direct dirt downwardly towards the dirt collection tray.

3. The vacuum cleaner of claim 1, wherein a second filter surrounds the pleated filter.

4. The vacuum cleaner of claim 1, further including a power cord.

5. The vacuum cleaner of claim 1, further including a rechargeable battery housing below the vacuum handle for holding rechargeable batteries.

6. The vacuum cleaner of claim 1, wherein the air passageway is divided in three sections across the length of the air passageway.

7. The vacuum cleaner of claim 1, further including a cooperating sweeper stand for storing the vacuum cleaner when not in use, the sweeper stand having a base with a horizontal opening, configured to hold the vacuum cleaner substantially vertical with its air inlet at the opening of the sweeper stand.

8. The vacuum cleaner of claim 1, further including a vacuum floor nozzle mountable at the nozzle opening for converting the vacuum cleaner to a stick vacuum.

9. The vacuum cleaner of claim 8, further including a pipe handle for mounting to the vacuum handle to extend the height of the vacuum cleaner.
