Description

  The present invention relates to a handle tube and a vacuum cleaner having the same, and more particularly, to a handle tube having a cyclone dust collecting device and a vacuum cleaner having the same.

  In general, a vacuum cleaner makes the inside of the cleaner body a vacuum state by forcibly circulating air by rotation of a motor, and at this time, a large amount of air is cleaned by a pressure difference generated between the inside and the outside of the cleaner body. It is a device that sucks dust and dust on the surface together with the air that is sucked.

  Furthermore, cyclone dust collectors are devices that separate particles in a fluid using centrifugal force.Since their structure is simple and resistant to high temperatures and high pressures, they have been widely used in industrial sites since ancient times, and are also used in vacuum cleaners. Used.

  A typical example of a vacuum cleaner equipped with such a cyclone dust collector is Korean Patent Application No. 1999-20704 (name: cyclone dust collector of vacuum cleaner).

  FIG. 1 is a perspective view of a vacuum cleaner having a cyclone dust collecting apparatus, which has been filed by the present applicant and described in Korean Patent Application No. 1999-20704. A vacuum cleaner 1 having a conventional cyclone dust collecting apparatus is largely composed of a cleaner body 3, a flexible hose 9 connected to the cleaner body 3, an extension tube 8, and a handle connected between the flexible hose 9 and the extension tube 8. It includes a tube 7 and a cyclone dust collecting device 21 coupled between the handle tube 7 and the extension tube 8.

  The cleaner main body 3 includes a dust collection chamber (not illustrated) in which a dust bag (not illustrated) provided inside the cleaner main body 3 is accommodated, and air containing external dust in the dust collection chamber. Is separated from a load drive chamber (not shown) in which a suction motor (not shown) for sucking the air is stored.

  A brush 10 is connected to a tip of the extension tube 8, and the brush 10 contacts a floor or a carpet on a surface to be cleaned, and an intake port is formed on a bottom surface of the brush 10.

  The cyclone dust collecting device 21 is connected between the handle 7 and the extension pipe 8 to separate dust such as dust contained in the air using centrifugal force.

  The handle 7 has a handle portion of a flexible hose 9 formed on one side so that a user can easily grip the handle 7.

  According to such a configuration, when power is applied, air containing dust and the like is sucked in through the suction port of the brush 10 by a suction force generated by driving the suction motor. Then, it flows along the extension pipe 8 and is sucked into the cyclone dust collector 21.

  At this time, the air sucked into the cyclone dust collecting device 21 descends while forming a swirling airflow, and dust and dust having large particles contained in the air are separated from the air by centrifugal force. The separated trash and the like descends along the inner wall surface of the dust cup 25 and is collected at a lower portion.

  The purified air moves along the handle tube 7 and the flexible hose 9 connected between the handle tube 7 and the cleaner body 3 and is sucked into the cleaner body.

  Thereafter, the dust collecting process performed in the dust collecting chamber (not shown) of the cleaner body 3 is the same as the dust collecting process of the general vacuum cleaner 1.

  However, in such a conventional vacuum cleaner, a handle portion must be separately provided on the handle tube, and particularly when a cyclone dust collecting device is provided, the load on the handle tube is uneven toward the cyclone dust collecting device. Therefore, it is difficult to smoothly operate the vacuum cleaner including the handle tube.

  Further, in the conventional vacuum cleaner, the suction driving force of the vacuum cleaner main body is a brush, an extension pipe connected to the brush, a cyclone dust collector, a handle pipe connected to the cyclone dust collector, the handle, and the handle. Because of the long transmission path including the flexible hose connected to the vacuum cleaner main body, there is a problem that a certain portion of the transmission path is exhausted and the dust collecting performance of the cyclone dust collector is inferior.

  SUMMARY OF THE INVENTION The present invention has been devised to solve the above-described conventional problems, and provides a handle tube of a vacuum cleaner that can be easily gripped and easily cleaned by a user with a simple configuration, and a vacuum cleaner having the same. Is to do.

  Another object of the present invention is to provide a light-weight handle tube of a vacuum cleaner and a vacuum cleaner including the same, since a separate handle portion is not required because of having a handle-shaped air flow path.

  According to an aspect of the present invention, there is provided a vacuum cleaner including a brush for sucking air containing external dust and a cleaner body for providing a suction force to the brush. The present invention is achieved by providing a vacuum cleaner in which a predetermined section includes a handle tube formed from a grip portion for gripping by a user.

  The handle may be formed by double bending between a tip coupled to the brush and a back end coupled to the cleaner body. Preferably, a notched portion is formed.

  In addition, the vacuum cleaner may further include a cyclone dust collecting device provided on the handle tube.

  And, the cyclone dust collector is configured to bypass the air flowing into the inside of the handle pipe, centrifugally separate the dust, and then detachably attach the cyclone body to the cyclone body and discharge the air. And a dust cup for collecting dust.

  Further, the cyclone body is coupled to the suction port for bypassing and sucking the air containing the dust sucked into the handle tube, a discharge port for discharging the air from which the dust is centrifugally separated, and the discharge port. And a waste separation grill.

  SUMMARY OF THE INVENTION It is an object of the present invention to provide a handle tube of a vacuum cleaner provided between a brush capable of sucking air containing external dust and a cleaner body providing suction force to the brush. This is attained by providing a handle tube of a vacuum cleaner, wherein an air flow path that connects the main bodies to each other is formed by a handle portion that can be gripped by a user.
