Abstract

A hand carriable surface cleaning apparatus, such as a cyclonic hand vacuum cleaner, is provided wherein the cyclone chamber has two dirt outlets.

First claim

What is claimed is:

1. A hand vac comprising:
(a) a body housing a suction motor and having an upper end, a lower end, a front end and a rear end;
(b) a cyclone bin assembly comprising a cyclone chamber that extends along a cyclone axis and has a sidewall, a cyclone air inlet, a cyclone air outlet, and a dirt collection chamber exterior to the cyclone chamber, the cyclone chamber comprising two dirt outlets provided in a lower portion of the sidewall of the cyclone chamber wherein a front dirt outlet is positioned on a front side of the cyclone chamber and a rear dirt outlet is positioned on a rear side of the cyclone chamber wherein a plane bisecting the housing along a front to rear direction extends through each of the front dirt outlet and the rear dirt outlet and wherein the lower portion of the sidewall of the cyclone chamber at an elevation of the dirt outlets is continuous from the front dirt outlet to the rear dirt outlet;
(c) a handle positioned rearward of the cyclone bin assembly, the handle extending upwardly and forwardly from a lower end of the handle to an upper end of the handle when the hand vac is oriented with the upper end above the lower end and the cyclone axis is vertically oriented; and,
(d) an air flow path extending from a dirty air inlet provided on the front end of the body to a clean air outlet and including the suction motor and the cyclone chamber.

2. The hand vac of claim 1 wherein at least a portion of the dirt collection chamber is positioned below the dirt outlets.

3. The hand vac of claim 1 wherein the cyclone air inlet is positioned at an upper end of the cyclone chamber, the cyclone air outlet is configured so that air exits the cyclone chamber through the upper end and the dirt outlets are positioned at a lower end of the cyclone chamber.

4. The hand vac of claim 1 wherein the hand vac is removably mountable on a base and, when so mounted, the hand vac and the base together define a surface cleaning apparatus in which the hand vac is an operating component of the surface cleaning apparatus when so mounted, and the at least one cyclone is oriented in a generally upright position when mounted on the base.

5. The hand vac of claim 1 wherein the hand vac is removably mountable on an upper portion of an upright vacuum cleaner wherein the upper portion is moveably mounted to a surface cleaning head between a storage position and a floor cleaning position.

6. The hand vac of claim 5 wherein the cyclone axis is oriented in a generally upright position when mounted on the upright vacuum cleaner and the upper portion is in a floor cleaning position.

7. The hand vac of claim 1 wherein the dirt collection chamber has a lower openable door.

8. The hand vac of claim 1 wherein at least a portion of the dirt collection chamber is positioned forward of the cyclone chamber whereby dirt travels downwardly into the dirt collection chamber from the dirt outlet positioned on a front side of the cyclone chamber and at least a portion of the dirt collection chamber is positioned rearward of the cyclone chamber whereby dirt travels downwardly into the dirt collection chamber from the dirt outlet positioned on a rear side of the cyclone chamber.

9. The hand vac of claim 1 wherein each of the cyclone chamber and the dirt collection chamber has a lower openable door and the lower openable doors are concurrently openable.

10. The hand vac of claim 9 wherein the lower openable door of the cyclone chamber is positioned above the lower openable door of the dirt collection chamber when the hand vac is oriented with the upper end above the lower end.

11. The hand vac of claim 1 wherein the handle has a hand grip portion and a finger receiving gap is provided between the handle and the cyclone bin assembly.

12. The hand vac of claim 1 wherein the upper end of the handle terminates and is connected to a rearward extension of the body.

13. A hand vac comprising:
(a) a body housing a suction motor and having an upper end, a lower end, a front end and a rear end;
(b) a cyclone bin assembly comprising a cyclone chamber having a sidewall, a cyclone air inlet, a cyclone air outlet, and a dirt collection chamber exterior to the cyclone chamber, the cyclone chamber comprising two dirt outlets provided in a lower portion of the sidewall of the cyclone chamber wherein a front dirt outlet is positioned on a front side of the cyclone chamber and a rear dirt outlet is positioned on a rear side of the cyclone chamber, wherein a plane bisecting the housing along a front to rear direction extends through each of the front dirt outlet and the rear dirt outlet and wherein the lower portion of the sidewall of the cyclone chamber at an elevation of the dirt outlets is continuous from the front dirt outlet to the rear dirt outlet;
(c) a handle positioned rearward of the cyclone bin assembly, the handle extending upwardly and forwardly along a substantially linear handle axis from a lower end of the handle to an upper end of the handle when the hand vac is oriented with the upper end above the lower end; and,
(d) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the cyclone chamber.

14. The hand vac of claim 13 wherein each of the cyclone chamber and the dirt collection chamber has a width in a direction transverse to an axis extending from the front side to the rear side of the cyclone chamber and the width of the cyclone chamber is similar to the width of the dirt collection chamber.

15. The hand vac of claim 13 wherein the dirty air inlet is provided on the front end of the body.

16. The hand vac of claim 13 wherein the cyclone chamber has a lower end wall, having a front portion, a rear portion and laterally opposed side portions extending between the front and rear portions of the lower end wall, the sidewall of the cyclone chamber having a front portion, a rear portion and laterally opposed side portions extending between the front and rear portions of the sidewall and wherein at least one laterally opposed side portion of the lower end wall abuts a corresponding laterally opposed side of the sidewall of the cyclone chamber.

17. The hand vac of claim 16 wherein the lower end wall of the cyclone chamber is openable and at least one laterally opposed side portion of the lower end wall abuts a corresponding laterally opposed side of the sidewall of the cyclone chamber when the lower end wall is in a closed position.

18. A hand vac comprising:
(a) a body housing a suction motor and having an upper end, a lower end, a front end, and a rear end;
(b) a cyclone bin assembly comprising a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber, the cyclone chamber having an upper end wall, a sidewall extending downward from the upper end wall to a lower end wall, a cyclone air inlet, a cyclone air outlet, a front dirt outlet, a rear dirt outlet wherein each of the sidewall of the cyclone chamber and the lower end wall has a front portion, a rear portion and laterally opposed side portions extending between the front and rear portions of the lower end wall, wherein at least one laterally opposed side portion of the lower end wall abuts a corresponding laterally opposed side of the sidewall of the cyclone chamber and wherein a plane bisecting the housing along a front to rear direction extends through each of the front dirt outlet and the rear dirt outlet and wherein the lower portion of the sidewall of the cyclone chamber at an elevation of the dirt outlets is continuous from the front dirt outl
