However, in the present invention, unlike the first embodiment described above, the dust separation unit for separating the dust prior to entering the auxiliary cyclone unit 320 is replaced by the filter unit 610 instead of the main cyclone unit.

The filter unit 610 may be provided in various forms and may include, for example, a dust collecting filter 611 and a filter mounting part 613.

The filter mounting part 613 is provided below the upper cover 315 to accommodate the dust collecting filter 611.

The dust collecting filter 611 is detachably accommodated in the filter mounting part 613 and may be formed of a sponge or a nonwoven fabric.

On the other hand, since the foreign matter such as dust is fixed to the dust collecting filter 611, cleaning or replacement is required periodically to prevent the suction force of the vacuum cleaner from lowering. Therefore, the dust collecting filter 611 should be easily separated from the cleaner body.

In this embodiment, the dust collecting filter 611 is easily separated after the upper cover 340 is separated. On the contrary, since the filter mounting part 613 for accommodating the dust collecting filter 611 is provided to be pulled out in a sliding manner, the dust collecting filter 611 may be separated from the vacuum cleaner.

The canister-type vacuum cleaner according to the present invention has been described so far, but the present invention is not limited to the above-described embodiment, and can be applied to an upright type vacuum cleaner or a robot cleaner.

Accordingly, those skilled in the art can make modifications without departing from the spirit of the present invention and such modifications are within the scope of the present invention.

The vacuum cleaner according to the present invention having the above configuration has the following effects.

First, the auxiliary cyclone unit is included in the main body unit and configured to be connected to the auxiliary cyclone unit when the dust bin is mounted to the main unit, so that the dust bin separated from the main unit does not include the auxiliary cyclone unit. Therefore, there is an advantage in that it is easy to clean the dust bin and the dust bin by simplifying the structure of the dust bin is required to separate the dust periodically. In addition, since the dust container includes only the main cyclone unit, there is an advantage that the dust container can be lightened.

Second, by separating the dust container from the main body unit, and by removing the upper cover of the dust container, there is an advantage that can easily empty the dust by flipping the dust container in the vertical direction.

Third, by configuring the outer wall of the main chamber made of a transparent material, it is possible to easily check the internal state of the dust chamber of the main chamber, where the relatively large dust is accumulated, it is possible to easily and accurately predict the time to empty the dust.

Fourth, considering that the general user of the vacuum cleaner is a housewife, it is preferable that the structure of the dust container that is periodically separated for emptying the dust is simple. The present invention is composed of a simple structure that can know the internal structure of the dust container, and other components constituting the dust collector such as auxiliary cyclone unit or communication duct is located in the body, thereby simplifying the structure of the dust container exposed to the user There is an advantage in terms of user convenience.
