Base Assembly for Floor Cleaner

Abstract

The present invention relates to a base assembly for a floor cleaner configured to clean a floor through linear reciprocation movement of two rag attachment pads through which the two rag attachment pads come close to and go away from each other. More particularly, the present invention relates to a base assembly for a floor cleaner capable of simultaneously conducting cleaning and sterilization of a floor by injecting steam onto the rag attachment pads while the rag attachment pads are being reciprocally moved.

Description

TECHNICAL FIELD[0001]The present invention relates to a base assembly for a floor cleaner configured to clean a floor through linear reciprocation movement of two rag attachment pads through which the rag attachment pads come close to and go away from each other, and more particularly a base assembly for a floor cleaner capable of simultaneously conducting cleaning and sterilization of a floor by injecting steam onto the rag attachment pads while the rag attachment pads are being reciprocally moved.Background Art[0002]In the prior art, publications, for example, Patent Documents are presented that disclose floor cleaners configured to clean a floor by linearly reciprocating opposite rag attachment pads.[0003]A floor cleaner body disclosed in the Patent Documents includes: a support member; a driving unit positioned on the support member; power conversion units configured to convert rotating movement provided from the driving unit into linear reciprocation movement; first and second ...

AI Technical Summary

Benefits of technology

The present invention described in this patent has various benefits. Firstly, it allows for floor wiping and sterilization using a single device. Secondly, it ensures that steam can be injected to rags and pads at a close position to allow for sufficient permeation. Thirdly, it reduces the likelihood of steam flowing backward into the body case by designing slope rails to avoid the use of slope wheels. Fourthly, it allows for a driving force to move the rag attachment pads using a single driving member. Lastly, it reduces the horizontal profile of the body case by positioning the driving motor at the rotation center rather than eccentrically.

Problems solved by technology

However, the conventional floor cleaner has problems as follows.

As a result, the floor cleaner has restrictions in introducing the floor cleaner into a gap below a sofa, furniture, a bed, etc.

In addition, because the construction of the belt and pulleys is complicated, and the power conversion units are arranged to be spaced away from each other to the opposite sides of the rotation axle of the driving motor, the width of the floor cleaner is also increased.

However, because a sliding structure should be added and assembled to the bearing, the construction of the floor cleaner becomes complicated, and the price of the bearing is very expensive.
