Abstract

The present disclosure includes a first housing configured in a cylindrical shape, an inlet port provided to the first housing to suck air therein, an inlet pipe communicating with the inlet port and extending to a front side of the housing with a length-directional axis positioned side by side with a ground surface, a cyclone forming part provided to separate dust from air flowing into the first housing, a second housing communicating with the first housing and coupled to a rear side of the first housing, a fan provided with the second housing to provide a suction force to enable air to be sucked into the first housing through the inlet port, a battery provided to supply power to the fan, and a handle part including a handle base coupled to a top side of the first housing and a handle body connected to the handle base.

First claim

The invention claimed is:

1. A cleaner, comprising:
a first housing configured in a cylindrical shape;
an inlet port provided to the first housing for air suction;
an inlet pipe communicating with the inlet port and extending to a front side of the first housing with a length-directional axis parallel to a ground surface;
a cyclone forming part provided within the first housing to separate dust from air flowing into the first housing;
a second housing communicating with the first housing and coupled to a rear side of the first housing, first and second lateral sides of the second housing being provided to right and left tangential surfaces of the first housing side by side with the length-directional axis of the inlet pipe, respectively;
a fan provided within the second housing to provide a suction force to enable air to be sucked into the first housing through the inlet port;
a battery provided within the second housing to supply power to the fan;
a handle part including a handle base coupled to a top side of the first housing and a handle body connected to the handle base; and
a battery receiving portion provided within the second housing to receive the battery therein,
wherein the fan, the battery, and the battery receiving portion are located between the first and second lateral sides of the second housing.

2. The cleaner of claim 1 , wherein the handle further comprises a connecting portion extending upward from the handle base to connect the handle base and the handle body together and wherein the handle body extends from a top end of the connecting portion to a rear side of the connecting portion so that a length-directional axis of the handle body is parallel to a top surface of the second housing.

3. The cleaner of claim 2 , wherein the length-directional axis of the handle body is located in a plane vertical to the ground surface by passing through a length directional center of the inlet pipe.

4. The cleaner of claim 1 , wherein the battery receiving portion is disposed to a left or right side within the second housing, and
wherein the fan is disposed to another side among the left or right side within the second housing.

5. The cleaner of claim 1 , further comprising a second housing cover provided on one lateral side of the second housing, the second housing having a multitude of air discharge holes.

6. The cleaner of claim 1 , further comprising a housing communicating hole formed in a circumferential surface of the first housing to enable the first housing and the second housing to communicate with each other.

7. The cleaner of claim 6 , the fan comprising:
a motor including a stator, a rotor rotated by the stator, and an impeller rotation shaft provided vertical to the ground surface by having the rotor joined thereto;
an impeller connected to the impeller rotation shaft to make air flow; and
a fan housing fixed to the second housing and receiving the impeller and the motor therein,
wherein a fan housing air inflow port for enabling air to flow into the fan housing is formed in a top surface of the fan housing, and
wherein the housing communicating hole is located at a position higher than that of the fan housing air inflow port.

8. The cleaner of claim 1 , wherein one portion of a bottom surface of the handle base is coupled to a top surface of the first housing and wherein another portion of the handle base is coupled to a top surface of the second housing.

9. The cleaner of claim 1 , wherein a battery insertion port communicating with the battery receiving portion is formed in a rear side surface of the second housing.

10. The cleaner of claim 9 , wherein the battery receiving portion has a height-directional length greater than a right-left width-directional length.

11. The cleaner of claim 1 , wherein the battery receiving portion has a height-directional length greater than a front-rear-directional length.
