Vacuum cleaner

Abstract

Disclosed is a vacuum cleaner capable of collecting at one place external air absorbed in the interior of the main machine through the absorption motor, exhausting the collected external air using strong blasting force. Usually, in case that dusts exist on the corner section or the gap section upon cleaning of the bottom part with use of the vacuum cleaner, a user could not bring the absorption nozzle close to the dusts accumulated section and sucking force does not reach that dust accumulated section, whereby the dust gets difficult to wipe out. Therefore, the vacuum cleaner has the closed space part in the internal rear part of the main machine in which the absorption motor is installed, and has, in the closed space part, the exhausting hole to which the blasting nozzle is joined in a free attaching and detaching manner. Thanks to such construction, the vacuum cleaner easily eliminates dusts by blowing down dusts accumulated on the corner section or the gap section, and sprays cleaning water using strong pressure in case that the spraying container is joined to the entry side of the exhausting hole, so that the bottom portion is more effectively cleaned.

What is claimed is:  
     
         1 . A vacuum cleaner such that an absorption motor is mounted in an internal rear part of a main machine and a dust filtering net is mounted in an internal front part of the main machine, the vacuum cleaner comprising: 
 a closed space part provided in an internal rear part of a main machine; and    an exhausting hole to and from which a blasting nozzle is freely attached and detached, provided in a rear part of the closed space part.    
     
     
         2 . The vacuum cleaner according to  claim 1 , wherein a joining pipe is prepared in an entry side of the exhausting hole, and a spraying container for exhausting solution contained in the spraying container, to the outside through the exhausting hole  16  using exhausting pressure discharged from the exhausting hole  16 , is mounted in the joining pipe in a free attaching and detaching manner.  
     
     
         3 . The vacuum cleaner according to  claim 1  or  claim 2 , wherein a plurality of second exhausting holes is formed on an outer surface of the closed space part, and a shutter plate having, in a front part, a connecting hole in response to the second exhausting hole, is installed in a freely movable manner in right and left directions.
