[0001]
BACKGROUND OF THE INVENTION
The present invention provides a cleaning function for cleaning a floor surface by rotating a brush at a high speed with a motor while supplying cleaning water, and a sewage suction function for sucking sewage generated by the cleaning from the floor surface by a squeegee suction action. The present invention relates to a surface cleaning cleaner.
[0002]
[Prior art]
A conventional general floor cleaning machine that cleans the floor while moving the brush head by pushing the operation handle is directed toward the brush as described in, for example, Japanese Patent Application Laid-Open No. 62-253020. By rotating this brush with a motor while dripping cleaning water, the floor surface is brushed (cleaned) and at the same time the cleaning wastewater is sucked and collected into the tank with a squeegee. If you want to use the cleaner differently from the original, for example, if the floor is very dirty, the detergent sprayed on the floor during brushing is dropped on the floor without collecting it at the same time as brushing. If you want to use it in such a way that you can continue brushing with a brush until the floor surface is clean and collect the cleaning sewage when the floor surface is clean In can not be dealt with in this machine.
[0003]
Therefore, for example, as shown in Japanese Patent Publication No. 10-513389, when brushing is performed by moving the brush and the liquid collecting blade (squeegee) in the cleaner head with their heights different from each other. A device has been conceived in which the collecting blade is retracted so as not to collect the sewage, and when the sewage is sucked in, the brush is retracted so as not to perform the brushing.
[0004]
[Problems to be solved by the invention]
However, the above-mentioned cleaner head can be switched separately between cleaning with a brush and suction of sewage with a liquid collecting blade, but these are not performed at the same time, so depending on how dirty the floor surface is. In some cases, a sufficient cleaning effect may not be exhibited, and since the cleaner head is manually operated back and forth, the cleaning workability is not good.
[0005]
Accordingly, the technical problem of the present invention is that a floor surface cleaning and cleaning machine that rotates a brush at a high speed with a motor to clean the floor surface simultaneously supplies cleaning water and brush cleaning and suction of sewage by a squeegee, A function that can be used in three or any two ways, such as allowing only water supply and cleaning to be performed at the same time without further suction, and further allowing only suction of sewage to be performed without water supply and cleaning. It is to have.
