Airflow diverter for upright-type vacuum cleaner and upright-type vacuum cleaner having the same

Abstract

An airflow diverter for an upright-type vacuum cleaner and an upright-type vacuum cleaner equipped with the same, are disclosed. The airflow diverter includes an inlet port formed on a cleaner body within which the vacuum generation device is received, air being drawn into the inlet port by the suction force generated by the vacuum generation, and a housing installed in the inlet port. The housing includes a first opening in communication with the vacuum generation device, a second opening in communication with the floor suction brush, and a third opening in communication with the auxiliary suction brush. A rotary knob is installed within the housing wherein if the rotary knob is turned to one direction by a predetermined angle, the rotary knob closes the third opening so that the vacuum generation device communicates with the floor suction brush, and if the rotary knob is turned to the other direction by a predetermined angle, the rotary knob closes the second opening so that the vacuum generation device communicates with the auxiliary suction brush.

Description

REFERENCE TO RELATED APPLICATION [0001] This application claims priority to co-pending Korean Patent Application No. 2003-69638 filed Oct. 7, 2003, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. FIELD OF THE INVENTION [0002] The present invention relates to an upright-type vacuum cleaner, and in particular to, an airflow diverter for an upright-type vacuum cleaner that can perform a cleaning by selecting one of a floor suction brush for cleaning a floor and an auxiliary suction brush for cleaning an area other than the floor, and an upright-type vacuum cleaner provided with the same. BACKGROUND OF THE INVENTION [0003] A conventional upright-type vacuum cleaner includes a cleaner body 10 and a floor suction brush 20 installed on the bottom of the cleaner body 10 to be movable 20 along a floor, as shown in FIG. 1. The interior of the cleaner body 10 is generally divided into a dust collection chamber at the uppe...

AI Technical Summary

Benefits of technology

[0010] Accordingly, the present invention addresses the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide an airflow diverter for an upright-type vacuum cleaner that allows the distance between a vacuum generation device and a floor suction brush to be reduced, thereby, improving the suction efficiency of the floor suction brush.

Problems solved by technology

Moreover, when cleaning is performed using the auxiliary suction brush 30, the cleaning is cumbersome because the extension tube 43 has to first be removed from the floor suction brush 20 to perform the cleaning, and removed again, to connect the extension tube 43 to the floor suction brush 20.

Thus, a heretofore un-addressed need exists in the industry to address the aforementioned deficiencies and inadequacies.
