Canister-type vacuum cleaner

Abstract

A canister-type vacuum cleaner has a cleaner body having a driving portion for generating a suction force and a dust chamber for collecting contaminants that are drawn in by the suction force of the driving unit; a suction extension pipe connected to the cleaner body; a suction brush disposed at an end of the suction extension pipe to draw in the contaminants of a cleaning surface with the suction force that is transmitted via the suction extension pipe; and an electrolytic liquid supply device disposed at the suction extension pipe, for spraying an electrolytic liquid to the cleaning surface through a lower side of the suction brush.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a canister-type vacuum cleaner, and more particularly, to a canister-type vacuum cleaner having an apparatus for generating an electrolytic liquid.[0003] 2. Description of the Prior Art[0004] Generally, a canister-type vacuum cleaner includes a cleaner body having a driving motor for generating a suction force, a suction extension pipe connected to the cleaner body, and a suction brush disposed at an end of the suction extension pipe.[0005] A dust chamber is provided in the cleaner body, having a filtering unit and a dust receptacle therein. Accordingly, contaminants from the cleaning surface are drawn in by the suction force of the driving motor into the dust chamber through the suction brush, filtered out at a filtering device, and collected in the dust receptacle.[0006] The suction extension pipe has a handle on which an on / off switch is provided. Accordingly, as a user grabs the handle and moves the suction ...

AI Technical Summary

Benefits of technology

[0011] The present invention has been made to overcome the above-mentioned problems of the prior art. Accordingly, it is an object of the present invention to provide a canister-type vacuum cleaner improved to clean stains on the floor or carpet not using a detergent but by using a simple method.

[0012] The above object is accomplished by a canister-type vacuum cleaner according to the present invention, including a cleaner body having a driving portion for generating a suction force and a dust chamber for collecting contaminants that are drawn in by the suction force of the driving unit; a suction extension pipe connected to the cleaner body; a suction brush disposed at an end of the suction extension pipe to draw in the contaminants of a cleaning surface with the suction force that is transmitted via the suction extension pipe; and an electrolytic liquid supply device disposed at the suction extension pipe, for spraying an electrolytic liquid to the cleaning surface through a lower side of the suction brush.

Problems solved by technology

However, stubborn stains on the floor or carpet can not be cleaned by the suction force of the driving motor alone, and thus, a floor-cloth brush or rotatable brush is rotatably disposed at the suction brush to clean the stained spots.

In the above suggestion's case, however, since there needs to be a cleaning liquid preparatory step of diffusing a certain amount of detergent in water, it is inconvenience for a user to use, and the cost increases.

Another problem is that the cleaning areas are often re-stained by the waste cleaning liquid.
