Abstract

A remaining water suction device having an air blowing function according to the present disclosure includes a suction and blowing integrated nozzle, a suction motor unit for providing a suction force to suction remaining water into the suction and blowing integrated nozzle, a drain tank for storing a liquid from the suction and blowing integrated nozzle, an air blowing module for supplying pressurized air to the suction and blowing integrated nozzle, and a main body with the suction and blowing integrated nozzle, the suction motor unit, the drain tank and the air blowing module mounted therein.

First claim

What is claimed is:

1. A remaining water suction device having an air blowing function, comprising:
a nozzle;
a suction motor that drives a suction fan to provide a suction force to suction liquid and air into the nozzle;
a drain tank that stores the suctioned liquid received through the nozzle;
a blowing motor that blows air to the nozzle;
a main body having the nozzle, the suction motor, the drain tank, and the blowing motor mounted thereto; and
a blocking plate that is moved to selectively switch a flow direction of the air blown from the blowing motor toward the nozzle or toward a flow path of the suctioned liquid within the main body,
wherein the main body further includes:
a suction chamber that receives the suctioned liquid and air from the nozzle;
a liquid discharge path formed to face the drain tank;
a partition plate having a first surface facing the suction chamber and provided to be inclined downward toward the liquid discharge path;
an air discharge path formed to face the suction motor;
a blowing duct formed to face the blowing motor; and
a through hole provided between the suction chamber and the blowing duct,

wherein the blocking plate is movable to selectively open one of the through hole or the blowing duct connected to the nozzle, and to selectively close another one of the through hole or the blowing duct, and
wherein the through hole is positioned to face the first surface of the partition plate such that when the blocking plate is positioned to at least partially open the through hole and to at least partially block the blowing duct, the air blown from the blowing motor passes via the through hole and into the suction chamber to blow the suctioned liquid toward the partition plate to be guided toward the drain tank and away from the air discharge path.

2. The remaining water suction device according to claim 1 , wherein the main body includes:
a first main body having the suction motor and the blowing motor mounted therein and the drain tank detachably coupled thereto; and
a second main body having an end coupled to the first main body and an opposite end coupled to the nozzle, the second main body being configured to guide the suctioned liquid water and air from the nozzle and the blown air toward the nozzle,
wherein the blocking plate is mounted to the second main body.

3. The remaining water suction device according to claim 2 , wherein the second main body includes:
the suction chamber;
the liquid discharge path;
the partition plate;
the air discharge path; and
the blowing duct.

4. The remaining water suction device according to claim 3 , further comprising:
a lever exposed to an outside of the second main body, wherein the blocking plate is connected to the lever and is moved by operation of the lever between a first position directing the blown air through the blowing duct and a second position directing the blown air through the through hole.

5. The remaining water suction device according to claim 1 , wherein the blocking plate is formed of an elastic material.

6. The remaining water suction device according to claim 1 , wherein the blowing motor outputs the blown air at a first air velocity when the blocking plate directs the blown air toward the nozzle, and at a second air velocity that is lower than the first velocity when the blocking plate directs the blown air toward the flow path of the suctioned liquid within the main body.
