Description

Floor cleaner {APPARATUS FOR CLEANING FLOOR}

The present invention relates to a floor cleaner, more specifically, to automatically operate to maximize the user's ease of use, as well as Velcro for attaching and detaching the cleaning member such as a mop or brush is fixed to the cleaner by physical force The present invention relates to a floor cleaner that does not detach the Velcro from the cleaner even if the cleaning or the like is continuously performed.

When cleaning the floor of a house or office, the mop is cleaned, and the conventional mop cleaning is still largely dependent on human labor. In other words, when using the conventional mop mechanism, the user has to perform the cleaning operation by reciprocating the mop mechanism while applying force, so when cleaning for a long time, not only the human body is uncomfortable, but the work is not efficient.

Meanwhile, although a steam cleaner has been recently developed for floor cleaning, this also has a problem that a human labor force is required to rub the floor repeatedly with a cleaner. In order to solve this problem, there was an attempt to minimize friction between the floor and the cleaner by installing a wheel on the bottom of the cleaner. However, such an attempt has a problem that results in sacrificing the original purpose of floor cleaning, considering that the dirt on the floor is removed by the friction force between the floor and the cleaner.

In particular, such a steam cleaner has a limitation in that it is not possible to clean the tile floor of the toilet or the veranda. In the case of water cleaning on the tile floor, when the user artificially presses the brush on the floor several times, the rub is removed.

In addition, in the case of the conventional steam cleaner, the mop was attached to or detached from the cleaner through the velcro fixed to the lower surface of the cleaner body. Due to frequent contact with water, the velcro itself was easily detached from the cleaner.

The present invention was derived to solve the above-described problems, the object of the present invention is automatically operated to maximize the user's ease of use, as well as Velcro for the removal of the cleaning member, such as a mop or brush cleaner with physical force It is fixed to it is to provide a floor cleaner that does not deviate from the Velcro from the cleaner even if you continue to clean the water.

As an aspect of the present invention for achieving the above object, the floor cleaner of the present invention, the drive unit; A power converter converting the rotational motion provided from the driver into power for a linear reciprocating motion; A moving member receiving linear power from the power converter and performing linear reciprocating motion; And a velcro fixed to the movable member for attaching and detaching a cleaning member, wherein the movable member includes first and second holes and between the first and second holes to fix the velcro to the movable member. Located fastening ribs are formed.

According to the floor cleaner according to the present invention, the mop or brush can reciprocate the floor automatically, thereby exhibiting a great cleaning effect without requiring labor of another person, and the mop or brush can automatically reciprocate the floor automatically. When the user does not feel significant vibration or shaking, the floor can be easily cleaned while changing the direction. Velcro for attaching and detaching the cleaning member such as a mop or brush is fixed to the cleaner by physical force. Even if the cleaning or the automatic cleaning of the cleaning member, etc. is continuously performed, the Velcro does not escape from the cleaner.
