Abstract

An apparatus for deodorizing dust particles includes a housing chamber, a powdering/granulating unit installed in the housing chamber, a deodorant disposed to be movable relative to the powdering/granulating unit, and a driving unit for driving the powdering/granulating unit or the deodorant. The deodorant is formed into granules or powders by a relative movement of the deodorant and the powdering/granulating unit, and thus obtained deodorant in granule or powder form is mixed with the dust particles.

Claims

1. A method for deodorizing dust particles by mixing the dust particles with a deodorant in the form of granules or powders.

2. A method for deodorizing dust particles, comprising the steps of:

forming a solid deodorant into granules or powders; and

mixing the dust particles with the deodorant in the form of granules or powders.

3. An apparatus for deodorizing dust particles, comprising:

a housing chamber;

a powdering/granulating unit installed in the housing chamber;

a deodorant disposed to be movable relative to the powdering/granulating unit; and

a driving unit for driving the powdering/granulating unit or the deodorant,

wherein the deodorant is formed into granules or powders by a relative movement of the deodorant and the powdering/granulating unit, and thus such deodorant in granule or powder form is mixed with the dust particles.

4. An apparatus for deodorizing dust particles, comprising:

a dust chamber for colleting dust particles therein;

a deodorant to be formed into granules or powders; and

a mixing unit for mixing the dust particles with the deodorant in the form of granules or powders.

5. A vacuum cleaner comprising:

an electric blower for suctioning dust particles;

a dust chamber for collecting the dust particles therein; and

a deodorizing apparatus for supplying a deodorant in the form of granules or powders into the dust chamber or at an upstream location of the dust chamber,

wherein the deodorant in the form of granules or powders is mixed with the dust particles by a suctioning force of the electric blower.

6. The vacuum cleaner of claim 5, further comprising a housing chamber is installed in and made to communicate with the dust chamber or a dust particle passageway upstream of the dust chamber, wherein the deodorant is loaded in the housing chamber to supply the deodorant in the form of granules or powders into the dust chamber.

7. The vacuum cleaner of claim 5, further comprising a powdering/granulating unit for forming a solid deodorant into granules or powders, wherein the solid deodorant is formed into granules or powders by the powdering/granulating unit.

8. The vacuum cleaner of claim 6, further comprising a powdering/granulating unit for forming a solid deodorant into granules or powders, wherein the solid deodorant is formed into granules or powders by the powdering/granulating unit.

9. The vacuum cleaner of claim 7, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other so that at least one of the deodorant and the powdering/granulating unit is moved by an drawing and moving action of a main body of the vacuum cleaner, and the deodorant is formed into granules or powders by the movement of said at least one of the deodorant and the powdering/granulating unit.

10. The vacuum cleaner of claim 8, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other so that at least one of the deodorant and the powdering/granulating unit is moved by an drawing and moving action of a main body of the vacuum cleaner, and the deodorant is formed into granules or powders by the movement of said at least one of the deodorant and the powdering/granulating unit.

11. The vacuum cleaner of claim 7, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other, and at least one of the deodorant and the powdering/granulating unit is driven manually so that the deodorant can be formed into granules or powders at any time a user wishes.

12. The vacuum cleaner of claim 8, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other, and at least one of the deodorant and the powdering/granulating unit is driven manually so that the deodorant can be formed into granules or powders at any time a user wishes.

13. The vacuum cleaner of claim 7, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other, and further comprising an electric driving unit for driving at least one of the deodorant and the powdering/granulating unit and a controller for controlling the electric driving unit to be operated constantly, periodically or intermittently to form the deodorant into granules or powders.

14. The vacuum cleaner of claim 8, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other, and further comprising an electric driving unit for driving at least one of the deodorant and the powdering/granulating unit and a controller for controlling the electric driving unit to be operated constantly, periodically or intermittently to form the deodorant into granules or powders.

15. The vacuum cleaner of claim 7, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other, and further comprising a cord reel for driving at least one of the deodorant and the powdering/deodorizing unit so that the deodorant is formed into granules or powders when a cord is extracted or retracted.

16. The vacuum cleaner of claim 8, wherein the deodorant and the powdering/granulating unit are disposed to be movable relative to each other, and further comprising a cord reel for driving at least one of the deodorant and the powdering/deodorizing unit so that the deodorant is formed into granules or powders when a cord is extracted or retracted.

17. The vacuum cleaner of claim 6, wherein the housing chamber is installed in the dust chamber or at a location above the dust particle passageway upstream of the dust chamber.

18. The vacuum cleaner of claim 6, wherein the housing chamber is provided with an opening for replacing the deodorant with a new one.

19. The vacuum cleaner of claim 5, further comprising a deodorant amount indicator for indicating a residual amount of the deodorant.

20. The vacuum cleaner of claim 5, further comprising at least one of an antibacterial agent and an aromatic compound as well as the deodorant, wherein the deodorant and said at least one of the antibacterial agent and the aromatic compound are formed into granules or powders to be mixed with the dust particles.
