The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of maximizing the dust compressive force provided by the compression unit while minimizing the space allocated to provide a compression unit for compressing the dust contained in the dust collecting unit.
In general, a vacuum cleaner is a device that sucks dirt and the like existing on the surface to be cleaned by using a suction force.
In such a vacuum cleaner, dirt, such as dust, is separated from the sucked air and collected in a predetermined space. Various techniques for separating dirt and the like from intake air have been applied to a vacuum cleaner, one of which is a cyclone method. In the cyclone method, the intake air has a rotational flow in a predetermined space, whereby dirt and the like are separated from the intake air by centrifugal force. The vacuum cleaner to which the cyclone method is applied typically includes a cyclone part for separating dust from the suction air for rotating flow of the suction air, and a dust collecting part for receiving the dust separated from the cyclone part.
Korean Patent No. 606794 discloses a technology for compressing dust contained in a dust collecting part by driving a pressure plate up and down. By compressing the dust contained in the dust collector as described above, there is an advantage that does not have to discharge the dust contained in the dust collector to the outside for a long time. And in the Republic of Korea Patent No. 606794, the rod-shaped flanger is vertically coupled to the center of the pressure plate, the flanger is driven up and down by the user's operation or the solenoid. At this time, as the pressure plate is driven up and down in the dust collector, a portion of the rod-shaped flanger is allowed to enter and exit the dust collector by the displacement of the pressure plate.
The vacuum cleaner having such a configuration requires not only a space for providing a dust collecting part therein but also a moving space of the flanger corresponding to the maximum displacement of the pressure plate. As a result, the vacuum cleaner has to allocate a relatively large space internally in order to have a structure for compressing the dust contained in the dust collecting unit, which causes a problem that the vacuum cleaner becomes large in volume. In addition, in the case where a large amount of dust is accommodated in the dust collector, it is necessary to provide a large compressive force to the pressure plate. However, there is a limit in providing a large compression force to the pressure plate by driving the rod-type flanger.
The present invention has been made to solve the above problems, it is an object of the vacuum cleaner to maximize the dust compression force provided by the compression unit while minimizing the space allocated to provide a structure for compressing the dust contained in the dust collector. .
According to the present invention, there is provided a cyclone unit for separating dust by centrifugal force from air sucked on a surface to be cleaned; A dust collecting unit having a dust collecting chamber for receiving dust separated from the cyclone unit; And a compression unit for compressing the dust contained in the dust collecting chamber. The vacuum cleaner having a cyclone dust collecting unit provided therein, the compression unit comprising: a driving unit for rotating the driving shaft; And a compression plate which is driven in a direction perpendicular to the drive shaft as the drive shaft rotates to compress the dust contained in the dust collecting chamber.
Here, the compression unit is coupled to the drive shaft in a straight line and driven to rotate with the drive shaft; And a connecting part connected to each of the screw and the compression plate to transfer the rotational force of the screw to the compression plate.
And, the screw,
The horizontally arranged on the upper side of the dust collector and a thread is formed in different directions on both sides of the center in the longitudinal direction, the compression plate may be driven up and down in the dust chamber as the screw rotates.
In addition, the connecting unit may include: first and second driving sliders each provided at a place where threads are formed in different directions on the screw and sliding in opposite directions as the screw rotates; First and second driven sliders respectively positioned on the lower side of the first and second driving sliders and sliding on an upper surface of the compression plate; First connecting rods whose ends are hinged to the first driving slider and the second driven slider, respectively; And a second connecting rod both ends hinged to the second driving slider and the first driven slider, respectively.
The first connecting rod and the second connecting rod may be hinged to each other at a point where they cross each other.
In addition, first and second guides for guiding sliding of the first and second driven sliders may be provided on an upper surface of the compression plate.
And, the drive unit, a drive motor for generating a rotational force; A drive shaft driven to rotate by the drive motor; And a rotational force transmission unit configured to transmit a rotational force of the drive motor to the drive shaft.

The cyclone unit and the dust collector may share one partition and be disposed in parallel with each other.
In addition, the partition wall, one side of the upper end may be opened so that the dust separated from the cyclone portion can be introduced into the dust collector.
The cyclone dust collecting unit may further include a filter member installed on an outer case of the cyclone dust collecting unit and filtering residual dust from air flowing out of the cyclone dust collecting unit after dust is separated from the cyclone dust collecting unit. Can be.
The vacuum cleaner may further include: a wire winding unit in which a wire for applying power to the vacuum cleaner from the outside is wound; And a filter cleaning unit which rotates by receiving rotational force from the wire winding unit when the electric wire is drawn out from the electric wire winding unit and shakes off dust accumulated on the filter member.
The wire winding unit may include a cylindrical winding member in which the wire is wound; And
And a winding gear coupled to one end of the winding member and rotatably coupled with the winding member, wherein the filter cleaning unit contacts the filter member on an outer circumferential surface thereof to shake off dust accumulated on the filter member.
