Description

Vacuum cleaner{A VACUUM CLEANER}

The present invention relates to a vacuum cleaner.

In general, a vacuum cleaner is intended to clean a surface by sucking dust, and consists of a dust collection room, a main body with a built-in suction motor, and a pipe with a suction head connected by a hose.

When the control switch provided on the handle of this vacuum cleaner is pressed, the suction motor is activated, and dust is sucked in through the suction head and pipe and collected in the dust collection room. In this case, dust and dirty particles existing on the surface are collected in the dust collector through the intake port, and the air with the dust and dirty particles filtered through the filter is discharged through the exhaust port.

However, in a conventional vacuum cleaner, the air discharged to the outside may contain harmful substances such as fine dust particles, bacteria, and viruses that are difficult to remove with a filter. In addition, the air discharged through the exhaust port of a conventional vacuum cleaner pollutes the indoor air by dispersing surrounding dust into the room, and the hot air discharged from the vacuum cleaner is especially likely to be discharged toward the human body of the cleaning worker. There are many problems that cause discomfort to workers.

Developed based on the above technical background, one embodiment of the present invention sprays the filtered air back into the suction pipe inlet and filters it repeatedly, thereby more thoroughly removing harmful substances such as fine dust, bacteria, and viruses, The object of the present invention is to provide a vacuum cleaner that can prevent discharged air from dispersing indoor dust and prevent unpleasant hot air from being discharged toward the cleaning worker's body.

A vacuum cleaner according to an embodiment of the present invention has a movable body unit with a plurality of wheels at the bottom, a suction pipe connected to the body unit to suck in external air and dust, and a suction pipe disposed inside the body unit for suction. A suction unit including a suction motor that provides power and a connection pipe connected to the suction pipe, a dust collection unit disposed inside the body and filtering air introduced from the suction pipe and collecting dust, connected to the body It may include an exhaust pipe that discharges air filtered from the dust collection unit to the outside, an exhaust unit including an exhaust motor disposed inside the body to provide power for discharging air, and a head connected to the suction unit.

The discharge pipe may include a first discharge pipe connected to the body portion and a second discharge pipe connected to the first discharge pipe.

The connection pipe is provided at one end of the connection pipe and may include an air control valve that controls the amount of air discharged.

The discharge pipe may include a first discharge pipe connected to the body portion, and a second discharge pipe whose end is connected to the first discharge pipe and the other end is connected to the head portion.

The head portion may be provided on the lower surface of the head portion and may include a guide hole that is connected to the second discharge pipe and guides the direction of air discharged from the second discharge pipe toward the suction pipe.

The head portion protrudes from a first head portion to which the suction pipe and the discharge pipe are connected, and one end and the other end of the first head portion, and is connected to the discharge pipe on the inner side and guides the direction of air discharged from the discharge pipe toward the suction pipe. It may include a second head portion provided with a hole.

The dust collection unit filters the air flowing in from the dust collection unit and the suction pipe, and is equipped with a HEPA filter to remove fine dust, ultrafine dust, and bacteria, and a deodorant to remove harmful odors. It may include a filter unit.

According to one of the above-described means for solving the problems of the present invention, the vacuum cleaner according to an embodiment of the present invention sucks in external dust and air, sprays the filtered air back into the suction pipe inlet, and repeatedly filters it to remove fine dust, bacteria, Harmful substances such as viruses can be removed more thoroughly, and the discharged air is sprayed back to the entrance of the suction pipe to prevent indoor dust from dispersing, and to prevent the discharged hot air from being discharged toward the cleaning worker's body. This can prevent discomfort to workers.
