Abstract

A cleaner includes: a suction unit; a main body that is connected with the suction unit and separates dust from air sucked through the suction unit; and a handle unit that is connected to the main body, wherein the main body includes: a first body and a second body; a sealing member for sealing a boundary between the first body and the second body; and a support body that supports the sealing member and has an opening that communicates with the suction unit.

First claim

What is claimed is:

1. A cleaner comprising:
a suction unit configured to receive air and dust from an outside of the cleaner;
a main body that is connected to the suction unit and configured to separate the dust from the air received through the suction unit; and
a handle unit connected to the main body,
wherein the main body is disposed between the suction unit and the handle unit and comprises:
a suction motor configured to generate suction force for causing the air and dust to be received through the suction unit,
a cyclone unit configured to separate the dust from the air received through the suction unit,
a first body that receives the cyclone unit, and
a second body that is connected to an upper portion of the first body and receives the suction motor,

wherein the suction unit comprises a pipe that is connected to the first body or to the second body and configured to guide the air and dust to the first body, and
wherein the pipe covers a portion of a boundary between the first body and the second body.

2. The cleaner of claim 1 , wherein a lower portion of the pipe is configured to be inserted into the first body, and an upper portion of the pipe is configured to be inserted into the second body.

3. The cleaner of claim 2 , wherein the first body and the second body are slide-coupled to the pipe.

4. The cleaner of claim 3 , wherein the pipe further comprises:
a main body connecting portion coupled to one or both of the first body and the second body; and
a guide pipe that extends from the main body connecting portion and is configured to guide the air to the first body.

5. The cleaner of claim 4 , wherein the suction unit is coupled to one or both of the first body and the second body in a direction crossing a direction in which the first body and the second body are slide-coupled to the pipe.

6. The cleaner of claim 5 , wherein the suction unit is coupled to both of the first body and the second body in a state in which the first body and the second body are coupled to the pipe.

7. The cleaner of claim 5 , wherein the second body includes a suction opening through which the air guided through the suction unit flows inside, and
wherein, when the second body is coupled to the first body, the suction opening of the second body and the opening of the pipe are aligned.

8. The cleaner of claim 1 , further comprising a sealing member that is disposed at the boundary between the first body and the second body, and
wherein a portion of the sealing member is covered by the pipe, and another portion of the sealing member is exposed to an outside of the pipe.

9. The cleaner of claim 8 , wherein the first body includes a seat at an inner surface of the first body, the seat being configured to support a lower end of the pipe.

10. The cleaner of claim 1 , wherein the first body and the second body are arranged along a gravity direction, and the second body is disposed above the first body.

11. The cleaner of claim 1 , wherein the pipe extends in a direction crossing a gravity direction and is connected to the first body and the second body.
