BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner having a deodorizing function for removing a bad smell of exhaust air from a cleaner body.

[0002]

2. Description of the Related Art Conventionally, a vacuum cleaner generally accumulates sucked dust in a dust collection chamber, and a foul odor due to the decay of the dust is generated in the cleaner body. Since the stench is exhausted from the exhaust port at the rear of the cleaner body, there is a problem that the user feels uncomfortable.

In order to solve this problem, a deodorant or a fragrance is disposed on the suction side of the electric blower in the cleaner body,
Japanese Unexamined Utility Model Publication No. 63-123255 discloses a configuration in which air sucked into a vacuum cleaner is exhausted by passing through a deodorant or a fragrance, thereby preventing the odor of exhaust from the vacuum cleaner body.
(A47L 9/00) and Japanese Utility Model Application Laid-Open No. 63-111858 (A47L 9/00).

However, in this configuration, the deodorant is located in the flow path of the exhaust gas flowing in the cleaner body, so that the deodorant component is always volatilized while the electric blower is being driven, so that the deodorant component is short-lived. There is a drawback that the odor preventing effect is not sustained due to volatilization during.

[0005]
