In this specification, a position where the rotation cover is rotated by the first angle is referred to as a first rotation position, and a position that is rotated by a second angle is referred to as a second rotation position.

11, the first open holding portions 621, 622, and 70, the second open holding portions 634 and 636, and the shaft supporting portion 630 are integrally formed. However, .

The hinge guide 610 may be integrally formed with the cleaner body 10 or may be coupled to the cleaner body 10. As another example, the first open holding portions 621, 622 and 70, the second open holding portions 634 and 636 and the shaft supporting portion 630 may be integrally formed with the cleaner body 10, (Not shown).

The first open and hold portions 621, 622 and 70 include an elastic member 70, a first support portion 621 for supporting one end of the elastic member 70, And a second support portion 622 supporting the second support portion 622.

The first support portion 621 may have a hole 623 through which the contact portion 185 of the hinge body 181 can pass. The contact portion 185 of the hinge body 181 may be in contact with the elastic member 70 through the hole 623. The abutting portion 185 presses the elastic member 70 according to the rotation angle of the hinge body 181 so that the elastic member 70 can contract. As another example, the two first support portions 621 may be spaced apart from each other to form the hole 623.

The elastic member 70 elastically supports the contact portion 185 of the hinge body 181 when the contact portion 185 passes through the hole 623 and contacts the elastic member 70. The elastic member 70 elastically supports the contact portion 185 of the hinge body 181 in a direction in which the rotation cover 15 is rotated upward.

[ . ≪ / RTI > The support protrusion 636 can support the hinge body 181 (for example, the second extension portion 183) when the rotation cover 15 is rotated by a second angle.

At this time, the support protrusion 636 may be positioned on the movement path of the hinge body 181 when the rotation cover 15 is rotated between the first angle and the second angle.

The shaft supporting portion 630 may include a seating groove 632 on which the hinge shaft 186 is seated.

A guide groove 625 may be formed on the bottom surface of the hinge guide 610 to guide movement of the contact portion 185 when the rotation cover 15 is rotated.

Hereinafter, the operation of the opening and maintaining means according to the position of the pivot cover will be described.

Fig. 12 is a view showing the rotating cover and the opening maintaining means in a state in which the rotating cover is not opened (unrotated state), Fig. 13 is a view showing the rotating cover in the state in which the rotating cover is rotated by the first angle, FIG. 14 is a view showing a rotating cover and an open / hold means in a state in which the rotating cover is rotated by a second angle; FIG. Fig. 15 is a perspective view of the cleaner main body in a state where the rotation cover is rotated by the second angle, and Fig. 16 is a view showing a state in which the dust separation mechanism is separated in a state in which the rotation cover is rotated by the second angle.

11 and 12, when the rotation cover 15 is engaged with the dust container 30, the contact portion 185 of the hinge body 181 is inserted into the hole (not shown) of the first support portion 621 623 and presses the elastic member 70, so that the elastic member 70 is contracted. When the elastic member 70 is contracted, one end of the elastic member 70 is spaced apart from the first support portion 621.

In this state, when the engagement of the first engagement portion 350 and the rotation cover 15 is released and the engagement of the second engagement portion 355 and the attachment portion 13 is released, The elastic member 70 pushes the contact portion 185 of the hinge body 181 by the elastic force of the member 70 so that the rotation cover 15 is rotated upward about the hinge shaft 186.

When the rotary cover 15 is rotated about the hinge axis 186 by the first angle? 1 in the process of pushing the elastic member 70 to the contact portion 185 of the hinge body 181, And the member 70 is brought into contact with the first support portion 621. Then, the elastic member 70 is stopped.

The end of the contact portion 185 of the hinge body 181 is positioned in the hole 623 of the first support portion 621 and contacts the one end of the elastic member 70. At this time, the elastic force of the elastic member (70) is larger than the downward rotational force due to the self weight of the rotary cover (15). Accordingly, the rotation cover 15 can be rotated by the elastic member 70 while being rotated by the first angle.

When an external force is applied to the rotary cover 15 and the rotary cover 15 is rotated downward in the state where the rotary cover 15 is rotated by the first angle, The pivot cover 15 may be rotated upward by the elastic member 70 so as to maintain the open state unless the pivot cover 15 is engaged with the first engagement portion 350. [

14 and 15, when the user lifts the rotary cover 15 upward in the state as shown in FIG. 13, the rotary cover 15 rotates about the hinge axis 186 of the hinge body 181 As shown in FIG. At this time, when the rotary cover 15 is rotated upward at the first rotation position, the contact portion 185 is separated from the elastic member 70 and is pulled out of the hole 623.

The hinge body 181 is in contact with the support protrusion 636 and interferes with the rotation of the rotation cover 15 in the upward direction. The hinge body 181 and / or the support ribs 634 are elastically deformed and the interference between the support protrusions 636 and the hinge body 181 Is released. The hinge body 181 of the pivot cover 15 is rotated in the upward direction by removing the force for rotating the pivot cover 15 upward in a state where the pivot cover 15 is rotated by the second angle? May be supported by the support protrusions 636 and maintained in a rotated state. The hinge body 181 or the supporting rib 634 is not elastically deformed by the rotational force of its own weight unless the downward rotating force is applied to the hinge body 181, The state of being seated on the support protrusion 636 is maintained.

15, the dust separating mechanism 20 can be separated from the cleaner main body 10. At this time, the dust separating mechanism 20 can be separated together with the air flow guide 80. At this time, the air flow guide 80 may be detachably connected to the underside of the dust separating mechanism 20. The air flow guide 80 serves to guide the air discharged from the dust separating mechanism 20 to the suction motor side, and may include a filter.

According to the present embodiment, since the rotating cover is held (opened) by the opening / holding means, there is an advantage that the dust container can be easily attached to or detached from the mounting portion without interfering with the rotating cover .

Further, when the rotating cover is not mounted on the dust container or is not engaged with the dust container, the opened state is maintained at the first rotating position, so that it is possible to easily check whether the dust container is not mounted or whether the rotating cover and the dust container are not coupled. .

In addition, since the rotation cover with the power transmission unit is rotated by the open / close unit, interference with the power transmission unit is prevented during the process of mounting the dust container to the mounting unit, Can be prevented.

In the above embodiment, the opening maintaining means includes the first opening maintaining portion and the second opening maintaining portion, but it is also possible to include only one opening maintaining portion depending on the type of the vacuum cleaner.
