Description

Vacuum cleaner {Vacuum cleaner}

This embodiment relates to a vacuum cleaner.

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

Such a vacuum cleaner includes 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 connection pipe 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 suction motor for generating a 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 forming an outer shape, a suction port through which air is sucked into the dust collecting body, a cyclone unit separating dust from the air sucked into the dust collecting body, and separated from the cyclone unit. A dust storage unit for storing dust and an outlet for discharging air from which dust is separated from the cyclone unit are included.

Meanwhile, the dust stored in the lower space of the dust collecting body, that is, the dust storage unit, continuously rotates along the inner circumferential surface of the dust collecting body by the rotational flow inside the dust collecting body while the vacuum cleaner is operating.

When the operation of the vacuum cleaner is stopped, the vacuum cleaner sinks to the bottom of the dust collecting body and is stored in a low density state.

Therefore, in the conventional dust collecting apparatus, when a predetermined amount or more of dust is stored in the dust collecting apparatus while the vacuum cleaner is operating, the dust rises while rotating along the inner wall of the dust collecting body, and is formed in the upper space of the dust collecting body. There is a problem in that the cyclone portion is violated, and thus the unseparated dust is discharged to the discharge port by piggybacking on the discharge airflow, so that dust collection performance is reduced.

In addition, when the operation of the vacuum cleaner is stopped, the dust sinks to the bottom of the dust collecting body as it is stored in a low density state. That is, since dust inside the dust collecting body occupies a volume too large for its weight, there is an inconvenience of frequently emptying the dust collecting body in order to maintain dust collecting performance.

An object of this embodiment is to propose a vacuum cleaner to increase the capacity of the dust stored in the dust storage unit.

Another object of this embodiment is to propose a vacuum cleaner in which the compression of dust stored in the dust storage unit is automatically performed.

Still another object of the present embodiment is to propose a vacuum cleaner for easily discharging dust stored in the dust storage unit.

In one embodiment, a vacuum cleaner includes: a dust separator configured to separate dust from air; A dust collecting body in which a dust storage unit for storing dust separated from the dust separation unit is formed; A cleaning member provided in the dust storage unit for cleaning dust attached to an inner circumferential surface of the dust storage unit; And a driving device for driving the cleaning member.

According to another aspect of the present invention, a vacuum cleaner includes: a first dust separator; A second dust separator for separating dust from the air discharged from the first dust separator again; A first dust storage unit storing dust separated from the first dust separation unit; A second dust storage unit storing dust separated from the second dust separation unit; A pressing member provided in the first dust storage unit to compress the dust stored in the first dust storage unit; And a cleaning member provided in the second dust storage unit and configured to clean the dust attached to the inner surface of the second dust storage unit.

According to the proposed embodiment, since the relatively large dust stored in the first dust storage unit can be compressed by the pressing member, there is an effect of maximizing the capacity of dust stored in the first dust storage unit.

In addition, as the dust collecting capacity of the first dust storage unit is maximized by the compressing action of the dust, the user has to remove the trouble of frequently emptying the dust stored in the dust collecting apparatus.

In addition, since the dust stored in the first dust storage unit is kept in a compressed state, when the dust of the dust collector is emptied, the dust is prevented from scattering, the dust can be easily discharged.

In addition, since the dust attached to the inner surface of the second dust storage unit is removed by the cleaning member, the dust of the second dust storage unit can be easily discharged to the outside, and the user should frequently clean the second dust storage unit. There is an advantage that the hassle is eliminated.

In addition, since the pressing member and the cleaning member are rotated using one driving motor, the structure of the driving apparatus is simplified.

In addition to the above configuration, the dust separation device 100 further includes a driving device 400 for driving the pressing member and the rotating member.

In detail, the driving device 400 includes a driving motor 440 and a power transmission unit for transmitting the power of the driving motor 440 to the pressing member 170 and the cleaning member 180.

In the power transmission unit, a first gear driven to the drive gear 430 coupled to the shaft of the drive motor 440, the drive gear 430 and coupled to the rotary shaft 172 of the pressing member 170, A gear 410 and a second driven gear 420 engaged with the first driven gear 410 and coupled to the rotation shaft 184 of the rotation member 180 are included.

That is, the main body 10 is formed with an opening 17 for exposing a part of the drive gear 430.

The driving motor 440 may be a motor capable of rotating in both directions (clockwise and counterclockwise). For example, a synchronous motor may be used as the driving motor 440. The synchronized motor is configured to be capable of forward and reverse rotation by the motor itself. When the force applied to the motor is greater than or equal to a predetermined value when the motor rotates in one direction, the rotation of the motor is converted to the other direction.

Therefore, when the drive motor 440 is rotated in one direction, the drive gear 430 is rotated in the same direction as the drive motor 440. When the driving gear 430 is rotated in one direction, the first driven gear 410 meshed with the driving gear 430 is rotated in a direction opposite to the driving gear 420. When the first driven gear 410 is rotated, the pressing member 170 coupled with the first driven gear 410 is rotated to compress the dust stored in the first dust storage unit 162.

Falls to the lower side of the second dust storage unit 164.

According to the present embodiment as described above, since the relatively large dust stored in the first dust storage unit 162 can be compressed by the pressing member 170, the capacity of the dust stored in the first dust storage unit is maximized. It works.

In addition, as the dust collecting capacity of the first dust storage unit is maximized by the compressing action of the dust, the user has to remove the trouble of frequently emptying the dust stored in the dust collecting apparatus.

In addition, since the dust stored in the first dust storage unit is kept in a compressed state, when the dust of the dust collector is emptied, the dust is prevented from scattering, the dust can be easily discharged.

In addition, since the dust attached to the inner surface of the second dust storage unit is removed by the cleaning member, the dust of the second dust storage unit can be easily discharged to the outside, and the user should frequently clean the second dust storage unit. There is an advantage that the hassle is eliminated.

In addition, since the pressing member and the cleaning member are rotated using one drive motor, the structure of the driving device is simplified.

Hereinafter, the operation of the vacuum cleaner will be described.

When the suction motor provided in the main body 10 is operated, air containing dust is introduced into the main body 10 through the main body suction part 14 by the suction force generated by the suction motor. Air introduced into the main body 10 is moved into the cyclone part 121 through the inlet 123 of the first dust separation part 120.

The air containing the dust introduced into the cyclone portion 121 is dropped while turning along the inner circumferential surface of the cyclone portion 121, and in this process, the air and dust are subjected to different centrifugal force by the weight difference. There is a separation between them. In addition, the dust separated air is filtered through the through-hole 137 of the filter member 135 and is discharged from the first dust separation unit 120 through the discharge hole 146.

On the other hand, the separated dust is introduced into the guide flow path 132 through the outlet 133 in the process of turning along the inner circumferential surface of the cyclone portion 121. In addition, the dust introduced into the guide flow path 132 falls downward through the opening 142 and flows into the first dust storage unit 162 through the first inlet 192.

Meanwhile, the air discharged through the discharge hole 146 is introduced into the connection duct 300 through the suction hole 302 formed in the connection duct 300. Some of the air introduced into the connection duct 300 is introduced into the second dust separation unit 200 through the inlet 202 of the second dust separation unit 200. In addition, the air introduced into the second dust separator 200 is turned along the inner circumferential surface of the second dust separator 200, and air and fine dust are separated in this process. The separated fine dust falls downward and is moved to the second dust storage unit 164 through the second inlet 194.

In addition, another portion of the air introduced into the connection duct 300 passes directly through the bypass hole 310 formed in the connection duct 300 to the discharge duct 350.

In addition, the air separated from the second dust separation unit 200 passes through the exhaust guide pipe 320 formed in the connection duct 300, and then moves to the discharge duct 350 to pass through the bypass hole 310. It merges with the air passing through it. The air moved to the discharge duct 350 passes through the suction motor and is discharged to the outside through a discharge part (not shown) of the main body 10.
