Description

[0001] The present invention relates to a vacuum cleaner having a detachable dust-separating dpp apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner to which a dust collecting device for separating dust or dirt (hereinafter referred to as dirt) contained in air by sucking outside air is detachably mounted.

BACKGROUND ART A dust collecting apparatus used in a vacuum cleaner, for example, a cyclone dust collecting apparatus is a device for separating dust contained in air by rotating air containing dust. There is no inconvenience that the dust bag must be replaced every time, And it is widely used in recent years.

Generally, in the cyclone dust collecting apparatus, a cyclone is installed long in a vertical direction, an air suction part is provided on a side surface of a cyclone body, an air discharge part is provided on an upper surface, and a dirt collecting unit is connected to a lower part of the cyclone. Therefore, the outside air flows into the side surface of the cyclone body, is lowered while turning, and the dirt separated from the air drops and is stored in the dirt collecting unit. However, such a cyclone dust collecting apparatus generally has only one single cyclone to separate the dirt only once, thereby reducing the efficiency of dirt separation.

In order to solve such a problem, in recent years, studies have been actively made on a multi-cyclone dust collecting apparatus having a plurality of cyclones. Such a multi-cyclone dust collecting apparatus is advantageous in that the dirt separation efficiency is improved by separating the dirt many times using a plurality of cyclones. However, since the multi-cyclone dust collecting apparatus has a plurality of cyclones, the volume of the apparatus must be increased. Therefore, only a part of the dust collecting unit or the like, such as a dust collecting unit, . As a result, when the user maintains and maintains the multi-cyclone dust collecting apparatus, the user removes only some components, such as a dirt collecting unit that is detachably installed, from the cleaner main body, There was.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a dust collecting apparatus of a large size, such as a multi-cyclone dust collecting apparatus, A vacuum cleaner is provided.

It is another object of the present invention to provide a vacuum cleaner capable of detachably mounting a bulky dust collecting apparatus such as a multi-cyclone dust collecting apparatus without significantly increasing the overall size of the vacuum cleaner.

According to one embodiment of the present invention, the vacuum cleaner includes a first opening for opening a part of the first surface and a second opening for opening a part of the second surface adjacent to the first opening A cleaner main body; A dust collecting device for separating dirt from the air; And a mounting part formed on the cleaner main body and detachably attaching the dust collecting device to the cleaner main body. The dust collecting device is configured to seal the first opening and the second opening of the cleaner main body when mounted on the mount part, Thereby forming an outer appearance of the base.

Here, the seat portion may be a recessed portion having a receiving space communicating with the first opening and the second opening of the cleaner main body and formed in a shape corresponding to the dust collecting device. At this time, the accommodation space may be formed to be inclined upward toward the second opening with respect to the horizontal plane.

The dust collecting device may be formed such that a part of the dust collecting device is protruded out through the first opening and the second opening when the dust collecting device is mounted on the seating part.

The dust collecting apparatus includes a first cyclone unit for introducing air and primarily separating dirt from the air by centrifugal force, and a second cyclone unit for separating the dirt from the air discharged from the first cyclone unit by centrifugal force, A part of the first cyclone unit protrudes out through the second opening, and a part of the second cyclone unit can protrude outward through the first opening. At this time, the first and second cyclone units may be detachably coupled to each other.

The first cyclone unit is capable of introducing air in the lower portion and discharging air in the upper portion.

The first cyclone unit includes a first cyclone chamber having an air inflow portion at a lower portion thereof, a central pipe provided at the center of the first cyclone chamber and guiding rotation of the air introduced through the air inlet, A first dirt collecting chamber in which dirt to be centrifugally separated from the first cyclone chamber is stored and a second dirt collecting chamber in which dirt disposed at one side of the first dirt collecting chamber and stored by centrifugal separation by the second cyclone unit is stored, . At this time, the first dirt collecting chamber may be formed in a shape having a semicircular cross section, and the second dirt collecting chamber may be formed in a shape having a rectangular cross section. Further, the first dirt collecting chamber may be formed such that at least a part of the side faces seal the second opening when the dust collecting apparatus is mounted on the seat portion.

Further, the first cyclone unit may further include a handle formed in the first dirt collecting chamber. At this time, at least a part of the handle may protrude outward through the second opening of the cleaner main body.

The second cyclone unit may comprise at least two cyclones arranged horizontally above the first cyclone unit. At this time, each of the two cyclones can at least partially protrude outward through the first opening of the cleaner main body.

The second cyclone unit includes a first cover for opening and closing the upper portion of the first cyclone unit, a grill member for filtering the dirt from the air discharged from the first cyclone unit, and a second cover for opening and closing the first opening of the cleaner body .

At this time, the first cover may be formed so as to simultaneously open or close the first and second dirt collecting chambers of the first cyclone unit. Further, at least a part of the grill member may protrude into the first cyclone chamber of the first cyclone unit and be maintained at a predetermined distance from the center pipe of the first cyclone unit. Further, the second cover may be formed to seal the first opening when the dust collecting apparatus is mounted on the seat portion.

As described above, the vacuum cleaner according to the present invention detachably mounts a large-sized dust collecting apparatus such as a multi-cyclone dust collecting apparatus having a plurality of first, second, and second cyclone units to the cleaner main body . Therefore, at the time of maintenance and maintenance of the dust collecting apparatus, the user can remove the entire dust collecting apparatus from the cleaner main body and then maintain and repair the dust collecting apparatus at a wide external place. As a result, it is possible to prevent inconveniences such that, after the removal of some parts such as a dirt collecting unit that is detachably installed, as in the conventional vacuum cleaner, from the cleaner main body, the remaining fixed parts are maintained and maintained in a narrow space in the cleaner main body .

In addition, since the first and second cyclone units of the dust collecting apparatus are detachably coupled to each other, maintenance and repair of the first cyclone unit and / or the second cyclone unit can be facilitated.

In addition, since the vacuum cleaner of the present invention is installed such that some parts of a bulky dust collecting apparatus such as a multi-cyclone dust collecting apparatus, that is, at least a part of the cyclones of the first cyclone unit and the second cyclone unit protrude outward, It is not necessary that the cleaner main body has a seating portion for mounting the dust collecting device equal to or larger than the entire width and the overall height of the dust collecting device. Accordingly, the vacuum cleaner of the present invention can be designed to have almost the same size as that of a conventional vacuum cleaner having a single cyclone, even when a bulky dust collecting apparatus is detachably mounted. As a result, the vacuum cleaner of the present invention can be installed so that a large-sized dust collecting device such as a multi-cyclone dust collecting device having excellent dust collecting performance can be detached without increasing the size of the cleaner main body.
