Abstract

An apparatus comprising one or more of a surface treatment apparatus having an air treatment member and a refuse container wherein at least one of the surface treatment apparatus and the refuse container is provided with one or more of (a) a dust control member providing a dust control agent comprising one or more of a liquid mist, positive ions and negative ions to an area below a dirt emptying outlet of a dirt collection region of the surface treatment apparatus; and, (b) a treatment applicator providing a treatment agent comprising one or more of a deodorizing agent, a disinfecting agent and a sanitizing agent to an interior volume of the air treatment member and an interior volume of the refuse container.

First claim

The invention claimed is:

1. An apparatus comprising one or more of a surface treatment apparatus having an air treatment member and a refuse container wherein at least one of the surface treatment apparatus and the refuse container comprises:
a dust control member providing a dust control agent comprising one or more of a liquid mist, positive ions and negative ions, wherein the dust control member directs the dust control agent to an area that is located below a dirt emptying outlet of a dirt collection region of the surface treatment apparatus when the dirt collection region of the surface treatment apparatus oriented such that dirt exits the dirt collection region in a downward direction.

2. The apparatus as claimed in claim 1 wherein the one of the surface treatment apparatus and the refuse container comprises both the dust control member and a treatment applicator that provides a treatment agent comprising one or more of a deodorizing agent, a disinfecting agent and a sanitizing agent to an interior volume of the refuse container.

3. The apparatus as claimed in claim 2 wherein the treatment agent comprises one or more of ozone, UV light and hydrogen peroxide.

4. The apparatus as claimed in claim 3 wherein the apparatus further comprises a hood which, when the dirt emptying outlet is open and the hood is in a deployed position, a closed volume is provided that includes the interior volume of the refuse container and an interior volume of the dirt collection region and the treatment agent is introduced into the closed volume.

5. The apparatus as claimed in claim 2 wherein the treatment agent comprises ozone and the refuse container further comprises an air flow path extending from the interior volume of the refuse container to a clean air outlet, the air flow path including a suction motor and an ozone destructor material.

6. The apparatus as claimed in claim 2 wherein the treatment agent is provided at pre-set intervals.

7. The apparatus as claimed in claim 2 wherein the treatment agent is provided by manual activation.

8. The apparatus as claimed in claim 2 wherein the treatment agent is provided subsequent to emptying of the dirt collection region.

9. The apparatus as claimed in claim 1 wherein the dust control member comprises one or more nozzles directed to the area below the dirt emptying outlet of the dirt collection region of the surface treatment apparatus when the dirt collection region of the surface treatment apparatus is oriented such that dirt exits the dirt collection region in a downward direction.

10. The apparatus as claimed in claim 9 wherein the one or more nozzles introduce the dust control agent to a location below the dirt emptying outlet and above the bottom of the refuse container.

11. The apparatus as claimed in claim 10 wherein the apparatus further comprises a hood which, when the dirt emptying outlet is open and the hood is in a deployed position, a closed volume is provided that includes the interior volume of the refuse container and an interior volume of the dirt collection region and the one or more nozzles introduce the dust control agent into the closed volume.

12. The apparatus as claimed in claim 9 wherein the surface cleaning apparatus comprises a dirt separation member having the dirt emptying outlet and the one or more nozzles are located around at least part of the perimeter of the dirt separation member.

13. The apparatus as claimed in claim 9 wherein the one or more nozzles are provided on the refuse container.

14. The apparatus as claimed in claim 1 wherein the dust control member is automatically actuated when the dirt emptying outlet is opened.

15. The apparatus as claimed in claim 1 wherein the dust control member is automatically actuated prior to the dirt emptying outlet being opened.

16. The apparatus as claimed in claim 1 wherein the one of the surface treatment apparatus and the refuse container which has the dust control member further comprises a dust control agent reservoir.

17. The apparatus as claimed in claim 1 wherein the refuse container further comprises a suction motor having a suction motor inlet end in air flow communication with the interior volume of the refuse container and a suction motor outlet end in air flow communication with the ambient atmosphere exterior to the refuse container.

18. The apparatus of claim 17 further comprising an air flow path extending from the interior volume to a clean air outlet, the air flow path including the suction motor and a refuse container air treatment member.

19. The apparatus of claim 18 wherein the refuse container air treatment member comprises a cyclone.

20. The apparatus of claim 19 further comprising a pre-motor filter positioned in the air flow path upstream of the suction motor.

21. The apparatus as claimed in claim 1 wherein the treatment agent is provided after a pre-set number of uses of the surface cleaning apparatus.
