Vacuum cleaner having wet cleaning function

Abstract

A vacuum cleaner with a wet cleaning function comprises a main body, a brush assembly having a contaminant suction port facing a cleaning surface, a brush of the contaminant suction port to rotate in contact with the cleaning surface, and a water exhaust nozzle, the contaminants suction port is fluidly communicated with the main body, and a front and a rear block parts formed at a front and a rear of the brush on a bottom surface of the brush assembly to selectively open or block a contaminant suction path by a friction force against the cleaning surface.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2005-54071 filed on Jun. 22, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a vacuum cleaner. More particularly, the present invention relates to a vacuum cleaner with a wet cleaning function. [0004] 2. Description of the Related Art [0005] Generally, a vacuum cleaner with a wet cleaning function can selectively perform a general cleaning and a wet cleaning. In the general cleaning, the cleaner draws in contaminants such as dusts from cleaning surfaces without moisture, and in the wet cleaning, the cleaner sprays water onto hard cleaning surfaces such as paper-covered floors, floors, and marbles to wipe off stains from the cleaning surfaces and draws in the contaminants with water.

AI Technical Summary

Benefits of technology

[0020] As described above, the vacuum cleaner with the wet cleaning function according to embodiments of the present invention opens or blocks the contaminant suction path by the front and the rear block parts so that the brush does not need to be ascended and descended. Additionally, the front and the rear block parts operate by friction force against the cleaning surface so that they do not need dedicated driving members. According to embodiments of the present invention, a vacuum cleaner with a cleaning function can be provided with very simple structure compared with a conventional vacuum cleaner with a cleaning function.

[0021] The vacuum cleaner can draw in contaminants while performing the wet cleaning with bristles of brush since the contaminant suction path is opened during the wet cleaning. In other words, the vacuum cleaner with the wet cleaning according to embodiments of the present invention does not need to perform a general cleaning to remove contaminants from the cleaning surface. Therefore, the cleaning time for wet cleaning can be shortened, compared to a conventional vacuum cleaner with a wet cleaning.

[0022] Further, as the vacuum cleaner with the wet cleaning according to embodiments of the present invention completes the wet cleaning and stops the air pump, water remaining in the water exhaust hose between the air pump and the water exhaust nozzle is blocked by air so as not to flow out from the water exhaust nozzle. Accordingly, if the vacuum cleaner with the wet cleaning according to embodiments of the present invention is applied, the circumstance around the vacuum cleaner does not get dirty by the remaining water.

Problems solved by technology

Accordingly, the conventional vacuum cleaner with the wet cleaning function needs a structure for raising or ascending and lowering or descending the brush, and therefore, the structure of the brush assembly is complicated.

Therefore, it takes almost twice the time taken to perform the mere general cleaning.

Therefore, the area around the vacuum cleaner be soiled by this remaining water.
