As in No. 24777, a box-shaped sterilizer was installed downstream of an electric blower to collect and kill bacteria contained in the exhaust flow.

[Problem to be solved by the invention]

In the above conventional example, only an aromatic agent or a sterilizer is applied to the exhaust gas that has passed through the dust collection filter, so it is possible to eliminate abnormal odors in the exhaust gas or sterilize the exhaust gas. The problem is that it is not possible to sufficiently eliminate strange odors caused by rotting dust collected in the dust collection filter, or to sterilize mold and bacteria generated in the dust collected in the dust collection filter, resulting in unsanitary conditions. It was hot.

Furthermore, the conventional example described above has a complicated structure in which the aromatic agent or disinfectant is stored in a box separate from the main case, and the box is installed between the dust collection filter and the electric blower. Therefore, it was troublesome to replenish air fresheners or disinfectants.

An object of the present invention is to eliminate the above-mentioned problems and to sterilize both the bag-like filter and the dust trapped in the bag-like filter, or both, even if the bag-like filter is left in the dust collection chamber. To provide a vacuum cleaner with a simple structure, which can eliminate foreign particles generated from the vacuum cleaner, and can easily attach a chemical for sterilization and/or deodorization to a dust collection chamber. .

[Means to solve the problem]
