Abstract

A vacuum cleaner includes a dust chamber, a dust bag provided in the dust chamber, and an electric blower for generating suction air flow for drawing and collecting dust and dirt in the dust bag. A deodorant is supplied into the dust bag by the suction air flow and directly attached to the dust and dirt. The deodorant has a granule or powder shape.

Claims (50)

1. A vacuum cleaner comprising:

a dust chamber;

a dust bag provided in the dust chamber; and

an electric blower for generating suction air flow for drawing and collecting dust and dirt in the dust bag,

wherein the dust bag includes:

a core mounted inside the vacuum cleaner and provided with an opening for drawing in the dust and dirt;

an envelop-shaped body for collecting the dust and dirt drawn via the opening of the core; and

a storage case containing therein a deodorant of a granule or powder shape and fixed to a surface of the core, the surface being positioned downstream of the suction air flow,

wherein the storage case is provided with an opening and a discharge port for communicating with the opening of the core,

wherein a suction force by the suction air flow traveling through the opening of the core and the opening of the storage case to the envelope-shaped body acts on the inside of the storage case so that the deodorant is discharged from the discharge port and mixed with the dust and dirt before entering into the envelope-shaped body, such that a mixture of the deodorant and the dust and dirt spreads into the envelope-shaped body, and

wherein one or more discharge ports for discharging the deodorant are provided on a surface of the storage case, the surface being substantially parallel to the air flow drawn via the opening of the core.

2. The vacuum cleaner of claim 1 , wherein the deodorant is supplied into the dust bag at a weight ratio ranging from about 0.5 wt % to about 5 wt % with respect to the dust and dirt in the dust bag.

3. The vacuum cleaner of claim 1 , wherein the deodorant has a granule diameter equal to or greater than 0.1 μm and equal to or less than 1 mm.

4. The vacuum cleaner of claim 1 , wherein the deodorant includes at least one of hydrophobic zeolite, active carbon and transition metal oxide.

5. The vacuum cleaner of claim 1 , wherein the deodorant has a functional material added thereto.

6. The vacuum cleaner of claim 5 , wherein the functional material is a hygroscopic material.

7. The vacuum cleaner of claim 5 , wherein the functional material serves to improve fluidity of the deodorant.

8. The vacuum cleaner of claim 5 , wherein the functional material is an antibacterial material.

9. The vacuum cleaner of claim 5 , wherein the functional material is an aromatic material.

10. A dust bag for a vacuum cleaner comprising:

a core mounted in the vacuum cleaner and provided with an opening for drawing in dust and dirt;

an envelope-shaped body for collecting the dust and dirt drawn via the opening of the core; and

a storage case containing therein a deodorant of a granule or powder shape and fixed to a surface of the core, the surface being positioned downstream of a suction air flow,

wherein the storage case is provided with an opening and a discharge port for communicating with the opening of the core,

wherein a suction force by the suction air flow traveling through the opening of the core and the opening of the storage case to the envelope-shaped body acts on the inside of the storage case so that the deodorant is discharged from the discharge port and mixed with the dust and dirt before entering into the envelope-shaped body, such that a mixture of the deodorant and the dust and dirt spreads into the envelope-shaped body, and

wherein one or more discharge ports for discharging the deodorant are provided on a surface of the storage case, the surface being substantially parallel to an air flow drawn via the opening of the core.

11. The dust bag for the vacuum cleaner of claim 10 , wherein the dust bag is made of one or more flammable materials.

12. The dust bag for the vacuum cleaner of claim 10 , wherein the deodorant is supplied into the dust bag at a weight ratio ranging from about 0.5 wt % to about 5 wt % with respect to the dust and dirt in the dust bag.

13. The dust bag for the vacuum cleaner of claim 10 , wherein the deodorant has a granule diameter equal to or greater than 0.1 μm and equal to or less than 1 mm.

14. The dust bag for the vacuum cleaner of claim 10 , wherein the deodorant includes at least one of hydrophobic zeolite, active carbon and transition metal oxide.

15. The dust bag for the vacuum cleaner of claim 10 , wherein the deodorant has a functional material added thereto.

16. The dust bag for the vacuum cleaner of claim 15 , wherein the functional material is a hygroscopic material.

17. The dust bag for the vacuum cleaner of claim 15 , wherein the functional material serves to improve fluidity of the deodorant.

18. The dust bag for the vacuum cleaner of claim 15 , wherein the functional material is an antibacterial material.

19. The dust bag for the vacuum cleaner of claim 15 , wherein the functional material is an aromatic material.

20. A dust bag for a vacuum cleaner comprising:

a core mounted in the vacuum cleaner and provided with an opening for drawing in dust and dirt;

an envelope-shaped body for collecting the dust and dirt drawn via the opening of the core; and

a storage case containing therein a deodorant of a granule or powder shape and fixed to a surface of the core, the surface being positioned downstream of a suction air flow,

wherein the storage case is provided with an opening and a discharge port for communicating with the opening of the core,

wherein a suction force by the suction air flow traveling through the opening of the core and the opening of the storage case to the envelope-shaped body acts on the inside of the storage case so that the deodorant is discharged from the discharge port and mixed with the dust and dirt before entering into the envelope-shaped body, such that a mixture of the deodorant and the dust and dirt spreads into the envelope-shaped body, and

wherein the storage case is provided with a detachable cover member which serves to cover the discharge ports.

21. The dust bag for the vacuum cleaner of claim 20 , wherein the deodorant is supplied into the dust bag at a weight ratio ranging from about 0.5 wt % to about 5 wt % with respect to the dust and dirt in the dust bag.

22. The dust bag for the vacuum cleaner of claim 20 , wherein the deodorant has a granule diameter equal to or greater than 0.1 μm and equal to or less than 1 mm.

23. The dust bag for the vacuum cleaner of claim 20 , wherein the deodorant includes at least one of hydrophobic zeolite, active carbon and transition metal oxide.

24. The dust bag for the vacuum cleaner of claim 20 , wherein the deodorant has a functional material added thereto.

25. The dust bag for the vacuum cleaner of claim 24 , wherein the functional material is a hygroscopic material.

26. The dust bag for the vacuum cleaner of claim 25 , wherein the functional material serves to improve fluidity of the deodorant.

27. The dust bag for the vacuum cleaner of claim 25 , wherein the functional material is an antibacterial material.
