Abstract

Provided is a vacuum cleaner including a cleaner body; a cover member installed at an upper portion of the cleaner body to be opened and closed and configured to form a part of a front surface and an upper surface of the cleaner body; a suction hose provided at a front surface of the cover member; a hole formed at the front surface of the cover member to be in communication with the suction hose; and an outlet port formed at a rear surface of the cleaner body to be located at a position lower than the hole, wherein air introduced through the hole is discharged to the outlet port via an inside of the cleaner body.

Claims

1. A vacuum cleaner comprising:

a cleaner body;

a cover member that is detachably coupled to an upper part of the cleaner body and configured to open and close a portion of the cleaner body, the cover member defining a part of a front surface and an upper surface of the cleaner body, a front portion of the cover member defining a suction hole; and

a suction hose that is detachably connected to the cover member and in communication with the suction hole,

wherein a rear surface of the cleaner body defines an outlet port at a position vertically lower than the suction hole, and

wherein air received through the suction hole is discharged to the outlet port via an inside of the cleaner body.

2. The vacuum cleaner according to claim 1, further comprising a dust container that is configured to be detachably coupled at the front surface of the cleaner body,

wherein the cover member is shaped to accommodate an upper portion of the dust container.

3. The vacuum cleaner according to claim 2, wherein the cover member includes a connector to which the suction hose is configured to detachably connect, the connector being in fluid communication with a suction port defined at an entrance of the dust container.

4. The vacuum cleaner according to claim 2, wherein the dust container includes:

a case configured to receive dust;

a cyclone configured to separate the dust in the case from the air; and

an upper cover coupled to an opened upper surface of the case to shield the cyclone, the upper cover defining a suction port through which the dust passes and a discharge port through which the air separated from the dust is discharged.

5. The vacuum cleaner according to claim 4, wherein the dust container is inclined relative to the cleaner body, and the discharge port is directed to the inside of the cleaner body.

6. The vacuum cleaner according to claim 5, further comprising a main motor that is located at a rear portion of the cleaner body and configured to generate a suction force.

7. The vacuum cleaner according to claim 5, wherein the suction port, the discharge port, and the outlet port are positioned in order from a front side toward a rear side along a center line of the cleaner body.

8. A vacuum cleaner comprising:

a cleaner body;

a cover member that is detachably coupled to the cleaner body and configured to open and close a portion of the cleaner body;

a dust container that is detachably coupled to the cleaner body;

a suction hose that is configured to guide dust to the cleaner body, the suction hose being detachably connected to the cover member and in communication with the dust container;

a base frame that defines divided internal spaces within the cleaner body;

a main motor that is configured to suction dust and to move air, the main motor being located in one of the internal spaces defined by the base frame;

a frame hole that is defined in the base frame and configured to discharge air discharged by the main motor;

a filter unit that faces the frame hole and is configured to filter the dust in the air discharged by the main motor; and

a PCB located inside the cleaner body and configured to be cooled by the air that has passed through the filter unit.

9. The vacuum cleaner according to claim 8, further comprising a suction guide that is configured to guide air that has passed through the dust container toward the main motor.

10. The vacuum cleaner according to claim 8, wherein the base frame includes:

a cover plate that divides an inside of the cleaner body into an upper side and a lower side, the main motor being located at an upper surface of the cover plate; and

a pair of side walls that are spaced apart from each other on the upper surface of the cover plate and define a space for accommodating the main motor.

11. The vacuum cleaner according to claim 10, wherein one of the pair of side walls is spaced apart from an outer end of the cover plate, and a sub-PCB that is separated from the PCB, the sub-PCB being positioned at one of the pair of side walls and configured to control a sub-motor that drives an agitator located at one side of the suction hose.

12. The vacuum cleaner according to claim 10, wherein

the pair of side walls include a first side wall and a second side wall,

the main motor is disposed adjacent to the first side wall, and

the frame hole is defined at a bottom surface of the cover plate corresponding to a space between the main motor and the second side wall.

13. The vacuum cleaner according to claim 8, wherein the PCB is located between a discharge port of the dust container that is located at the cleaner body and an outlet port of the cleaner body.

14. The vacuum cleaner according to claim 8, wherein the base frame includes a cover plate that divides an inside of the cleaner body into an upper side and a lower side, the main motor being installed at an upper surface of the cover plate, the vacuum cleaner further comprising a barrier that extends downward from a lower surface of the cover plate and divides the inside of the cleaner body to define a space for accommodating the filter unit and a space for accommodating the PCB, the base frame defining a barrier hole at the barrier that is configured to allow the flow of air that has passed through the filter unit toward the PCB.

15. The vacuum cleaner according to claim 14, further comprising a battery unit that is located under the filter unit, wherein the battery unit is cooled by air that has passed through the filter unit and not directed to cooling the PCB.

16. A vacuum cleaner comprising

a cleaner body;

a cover member that is attached to the cleaner body and configured to open and close a portion of the cleaner body;

a suction hose that is detachably coupled to the cover member and in communication with a dust container to guide dust to the dust container;

a main motor located inside the cleaner body and configured to generate a suction force;

a battery unit located inside the cleaner body;

a base frame that defines a divided space in which the main motor and the battery unit are located;

a frame hole defined at the base frame to direct the air discharged from the main motor to the battery unit; and

a filter unit located inside the cleaner body and configured to filter out the dust in the air discharged from the main motor.

17. A vacuum cleaner comprising

a cleaner body;

a cover member coupled to an upper portion of the cleaner body and configured to open and close a portion of the cleaner body, the cover member defining a part of a front surface and an upper surface of the cleaner body;
