Description

Duct cleaner {Duct cleaner}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a robot cleaner for cleaning a duct which can be remotely controlled, and more particularly, to a duct cleaner suitable for cleaning dust and foreign matter remaining in a duct installed in a building or the like.

Generally, dust and foreign matter (for example, mold, bacteria, etc.) contained in the air are left in the duct due to the air entering and exiting the duct for ventilation and the ventilation duct. Such harmful elements such as dust and foreign substances are introduced into the room through the duct when ventilating or purifying air, which can cause diseases of the bronchial system, thereby causing harmful effects on the human body and causing indoor air pollution.

In particular, a duct installed on a ceiling such as a building or a subway is provided with cool air during the summer to cool the platform. However, if cold air is supplied to cool the platform during the winter season, The dust accumulated by the wind generated by the operation of the air is blown out to the platform together with the cold air to spoil the clothes of the people in the room or the platform or to be inhaled into the circulatory system at the time of breathing, Of the disease.

In order to prevent foreign substances such as dust accumulated in the duct from being ejected to cause discomfort to people or to cause diseases of the circulatory system, it is necessary to periodically remove dust or foreign matter remaining in the duct, but the duct can not be separated Accordingly, a separate cleaning robot has been used.

Such a duct cleaning robot has already been proposed variously. As an example of a conventional cleaning robot, a 'duct cleaning robot cleaner' is disclosed in Patent Publication No. 10-0188517,

The 'duct cleaning robot cleaner' described above includes a hopper, a controller, operating means for inputting an operation command to the controller, a drive wheel drivably mounted on the lower portion of the hopper, and a pair of lights A rotating camera provided between the pair of illuminating means, a rotating circular plate rotatably supporting the pair of illuminating means and the recording camera, and a rotating disk provided on the base, A drive shaft mounted on the rotation shaft of the drive motor for rotating the rotation shaft by 90 °, a drive shaft rotated in accordance with the drive force converted by the drive power conversion means, A brush for blowing off the dust in the duct while being rotated in accordance with the rotation of the brush, A lifter installed at an upper portion of the base to move the driving motor up and down by an angle? (-45 to +150) around the horizontal line of the base so as to move the brush up and down; Guiding means for guiding the lifter to move up and down by a driving force of the lifter driving motor and a slider for guiding the operating rod of the lifter by connecting the operating rod of the lifter and the slider of the guiding means, A brush upward position detecting means for detecting an upward position of the brush when the driving motor is raised upward by 150 DEG with respect to the horizontal plane of the base; A brush downward position detecting means for detecting a downward position of the brush when it is downwardly rotated by 45 ° with respect to the horizontal plane of the base, And a.

In addition, various conventional cleaning robots have been proposed. However, such a conventional cleaning robot is provided with a spraying device for spraying rotary brushes or high-pressure compressed air toward the front end side of the body which is advanced and retracted by the rolling means, Dust or the like accumulated in the duct is scattered by using a rotary brush or an injector provided therein, and the scattered dust is sucked and collected by a dust collector installed outside the duct.

Therefore, there is an advantage that the dust accumulated in the duct can be cleaned without disassembling the duct.

However, in the conventional cleaning robot as described above, in order to suck dust that is scattered during cleaning and take it out, it is necessary to seal the duct of the part to be cleaned completely, and also the air outlet of the cooling / heating air installed in the duct, There is a problem that the dismantled portion is sealed with vinyl or the like and the duct portion connected to the air conditioner is also sealed.

In addition, when ductwork is removed and ductwork is cleaned by sealing the demolished parts, scattered dust in the ducts will leak out through openings such as ducts or cleaning workpieces, And the like. In order to prevent this, there is a problem in that it is necessary to additionally cover the wall, the floor, the fixtures, etc. of the office with the use of wide vinyl. Especially, if you want to clean a duct in a high-end office, a living room, a hotel with a high level of interior decoration, or a department store or a shopping mall where commodity displays are displayed, There is a problem to be written.

Accordingly, in the case of the conventional cleaning robot, there is a problem that workability is deteriorated due to time and labor required for cleaning the duct, time and labor required for the preliminary preparation work and the post-repair work. In addition, there is a problem that the worker suffers scattered dust generated during the duct cleaning operation and suffers harm to the health of the worker, which causes many workers to avoid the duct cleaning work.

Furthermore, since ducts must be completely sealed in order to clean the duct, there is a problem in that the working time is limited due to work on a holiday or night when the building is empty.

The present invention has been made to solve the above problems of the conventional art, and it is an object of the present invention to provide a dust collecting apparatus and a dust collecting apparatus capable of removing dust and foreign matter remaining in a duct while moving along a duct by remote control, And it is an object of the present invention to provide a duct cleaner capable of collecting dust and foreign matter scattered during cleaning.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a duct cleaner comprising: a main body having front and rear wheels mounted to be able to travel along an inside of a duct, A wheel driving unit for rotating the front wheel or the rear wheel; A dust hairs portion provided on the running main body and having a brush which comes into contact with an inner peripheral surface of the duct at a front side of the running main body to remove dust and foreign matter; A brush driving unit for rotating the brush; A suction unit for sucking dust and foreign matter separated from the inner circumferential surface of the duct by suction through the suction port; A camera installed on a rotary plate rotatably installed in the traveling body and photographing the inside of the duct; An illumination unit installed on the rotary plate for irradiating light to an area to be photographed by the camera; A rotation driving unit for rotating the rotation plate; A remote control unit including a control unit for independently controlling operations of the wheel driving unit, the brush driving unit, and the rotation driving unit, and an input unit for inputting an input signal to the control unit; Respectively.

The duct cleaner according to the present invention is installed in a duct to move dust and foreign substances remaining in the duct while moving the duct along the duct by remote control. At the same time, dust and foreign matter in the duct can be cleaned by sucking dust, It also has the advantage of collecting dust and foreign matter.
