Description

{AUTPMATIC CLEANER WITHOUT ELECTRICAL POWER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-power source automatic cleaner, and more particularly, to a non-power source automatic cleaner in which a user rotates the front and rear roller brushes in opposite directions to each other, The present invention relates to a non-power source automatic vacuum cleaner capable of automatically collecting foreign matter in a center tray and selectively wiping water simultaneously.

In general, the traditional floor cleaning method uses a broom to sweep away dust or debris, and then wipes dust or dirt off the floor using a rag.

However, such a conventional floor cleaning method requires the floor to be rubbed again with a mop after bending the waist and repeatedly rubbing the body repeatedly over a long period of time in a bowed state, and thus the worker is physically strong and takes a long time .

In order to solve these problems, various vacuum cleaners have been developed and used. Typical examples of vacuum cleaners are vacuum cleaners for absorbing dust or foreign substances on the floor by using negative pressure formed by driving an electric motor.

In the case of a vacuum cleaner, there is an advantage that a worker can perform cleaning work in a comparatively comfortable posture without applying a lot of power. However, the vacuum cleaner basically consumes electricity and merely collects dust or foreign substances on the floor by sound pressure Accordingly, there is a problem that the dust and foreign matter adhered to the floor surface can not be removed, and there is a problem that additional wiping is required, and after the suctioned air is filtered, the dust is strongly discharged rearwardly so that fine dust is discharged by the exhaust air, There is a problem in that a sound pressure is formed inside the main body and dust and foreign substances are sucked together with the air. Therefore, there is a problem that a high noise is generated due to the high rotation of the suction motor for forming the negative pressure.

As an example for solving the problem of the above-described vacuum cleaner, Korean Patent Registration No. 10-1144949 (Registered May 23, 2012) discloses a manual cleaner that sucks dirt and dust by rotating a rotary brush to perform cleaning, And a main body in which the interior of the main body is empty so as to receive the dust; A rod made of a plurality of rods which is rotatably attached to the upper portion of the main body so as to be cleaned by pushing by hand and which has a small thickness and is inserted into the rod having a large thickness so as to be adjustable in length, ; A plunger inserted between the plunger and the main body to connect the plunger to the main body so that the plunger can be pivotally coupled to the main body; A first rotary brush mounted horizontally on a front lower portion of the main body to rotate and fixed to the main body by lifting dust and dirt on the floor by a vertical rotation of a vertical rotation motor attached to the rotation axis in a vertical direction; And is rotatable by friction with the bottom when the main body is pushed by the pushing rod, and the circumferential surface of the circumferential surface of the circumferential surface of the circumferential surface A rolling wheel made of rubber so that teeth are formed at regular intervals on the floor and slid on the floor at the time of rotation; The horizontal sprocket is gear-engaged with the teeth of the rolling wheel so as to rotate together with the rolling wheel by the rolling of the rolling wheel, A second rotating brush for sweeping into the center of the second rotating brush; And a hinge attached to both sides of the main body so as to be opened and closed so as to be attached to a rear surface of the main body by a hinge connection, thereby allowing the dust and the dust stored in the main body to be discharged from the main body. A vacuum cleaner pulling handle attached to the front of the main body so as to open the vacuum cleaner door so as to protrude in a half moon shape; A vacuum cleaner pull-in string connected to one side of the upper portion of the vacuum cleaner door so that the vacuum cleaner door can be opened by pulling the vacuum cleaner pull-off handle; A vacuum cleaner door pulling spring connected between a lower end of the cleaner cleaner door and an inner upper end of the cleaner cleaner door so as to keep the cleaner cleaner door in a closed state so as to always pull the lower end of the cleaner cleaner door; A main wheel which protrudes from a lower center rear of the main body to allow the main body to move forward and backward by rolling friction while maintaining a predetermined distance from the floor; The dust collecting apparatus according to any one of claims 1 to 4, further comprising: a dust collecting unit for collecting dust and dirt accumulated in the dust collecting unit, And a dust receiving guide for connecting the dust suction holes of the main body in an oblique manner to the main body of the vacuum cleaner.

In the case of a passive smart cleaner having a rotary brush according to Korean Patent No. 10-1144949, the first rotary brush extending horizontally at the center is rotated by the frictional force with the floor to collect the dust into the body, The second rotating brush extending vertically is rotated in conjunction with the rotation of the first rotating brush to collect the dust while collecting dust or foreign matter without providing any external energy such as electricity.

However, in the case of a passive smart cleaner having a rotary brush according to Korean Patent No. 10-1144949, when the vacuum cleaner is pushed, the first and second rotary brushes rotate in the direction of collecting the dust, but when the vacuum cleaner is pulled, And the second rotary brush is reversely rotated, so that the cleaning is not performed. The dust collecting depends on only the first rotary brush, and the rotational speed of the first and second rotary brushes is equal to the moving speed of the cleaner There is a problem in that the effect of moving dust or foreign matter into the main body is insignificant and there is a problem that water wiping can not be performed at the same time and water wiping must be performed separately.

The present invention provides a non-powered automatic cleaner capable of automatically collecting dust or foreign matter on a floor surface by manual operation of a user holding a bag portion and pushing or pulling the body on a floor surface without power supply ≪ / RTI >
