Vacuum cleaner and dust bag for vacuum cleaner
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.
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.
