Description

A dust collecting unit of vacuum cleaner

The present invention relates to a dust collector of a vacuum cleaner.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a dust collecting apparatus of a vacuum cleaner in which dust collecting capacity is increased.

In general, a vacuum cleaner is a device that sucks air containing dust by using a vacuum pressure generated by a suction motor mounted inside the body, and then filters the dust inside the body.

The vacuum cleaner may include a suction nozzle for sucking air containing dust, a cleaner body in communication with the suction nozzle, an extension pipe for guiding air sucked from the suction nozzle toward the cleaner body, and air passing through the extension pipe. A connector is connected to the cleaner body. Here, a nozzle suction port having a predetermined size is formed at the bottom of the suction nozzle to allow the air containing the dust accumulated on the floor to be sucked.

On the other hand, the inside of the cleaner body, there is provided a drive device for generating an air suction force to suck the outside air containing dust to the suction nozzle.

In addition, the dust collector is detachably mounted to the cleaner body to separate and store dust. The dust collector performs a function of separating and storing dust contained in the air sucked from the suction nozzle.

In detail, the dust collecting apparatus includes a dust collecting body, an inlet for allowing air to be sucked into the dust collecting body, a cyclone portion for separating dust from the air sucked into the dust collecting body, and dust separated from the cyclone portion. The dust storage unit and a discharge port through which the dust is separated from the cyclone portion is discharged.

When the vacuum cleaner is stopped while the dust separation process is performed in the dust collector, the separated dust is stored in a low density state in the dust storage unit.

According to the conventional dust collector, since the dust stored in the dust storage unit occupies a volume too large for its weight, there is an inconvenience of frequently emptying the dust of the dust collector in order to maintain dust collection performance.

Therefore, in recent years, in order to improve the convenience of using a cleaner, efforts have been made to maximize the capacity of dust stored in the dust collector and at the same time improve dust collection performance.

An object of the present invention is to provide a dust collecting device of a vacuum cleaner to increase the dust collecting capacity.

Another object of the present invention is to provide a dust collector of a vacuum cleaner in which the compressibility of dust can be improved.

According to the present invention there is an advantage that the dust stored in the dust storage unit is compressed by a plurality of pressure members that are rotated separately from the spaced apart position to increase the dust compression efficiency.

In addition, according to the present invention, since the plurality of pressing members compress the dust while rotating at both ends of the fixing member, the shape of the dust storage unit can be variously configured.

That is, since only the rotating radius portion of the pair of pressing members may be formed in a circular shape, and the remaining portions may be formed in various shapes, not circular, a larger amount of dust may be compressed and stored by various shapes of the dust storage unit. There is an effect that the storage capacity of the dust stored inside the dust collector can be further increased.
