Abstract

A robot purifier including: a purifying part which draws, purifies, and discharges air; and a driving part which is located at a lower end of the purifying part and is capable of autonomous driving, wherein the purifying part is capable of rotating 360 degrees horizontally, and the purifying part also is capable of rotating vertically such that an air intake direction and an air discharge direction in the vertical and horizontal directions is controllable.

First claim

The invention claimed is:

1. A robot purifier comprising:
a purifying part which draws, purifies, and discharges air; and
a driving part which is located at a lower end of the purifying part and is capable of autonomous driving,
wherein the purifying part is capable of rotating horizontally.

2. The robot purifier of claim 1 , wherein the driving part 200 comprises:
a body;
a ball bearing which is fixed to the body; and
a gear which is fixed on the ball bearing to be rotatable and includes gear teeth,
wherein a lower cover is located at an outer lower end of the purifying part, a window lower cover is located at a portion of the center of the lower cover, which is connected to the driving part, and a gear head is located on one side of the window lower cover, and
wherein an outside of the gear head is engaged with an inside of the gear.

3. The robot purifier of claim 2 , wherein the gear teeth of the gear are engaged with a gear of a power member of the driving part.

4. The robot purifier of claim 3 , wherein the center of the gear and the center of the gear head are opened,
wherein a connector is provided to pass through the center of the gear and the center of the gear head, which are opened, and
wherein the purifying part and the driving part are connected to each other by the connector to rotate leftwards and rightwards.

5. The robot purifier of claim 4 , wherein a cable is provided to pass through the center of the gear and the center of the gear head, which are opened, and electric power and an electrical signal are transmitted from the driving part and are received by the purifying part through the cable.

6. The robot purifier of claim 1 , wherein the purifying part is capable of rotating 360 degrees horizontally.

7. A robot purifier comprising:
a purifying part which draws, purifies, and discharges air; and
a driving part which is located at a lower end of the purifying part and is capable of autonomous driving,
wherein the purifying part is capable of rotating 360 degrees horizontally, is capable of rotating vertically, and an air suction direction and an air discharge direction in the vertical and horizontal directions is controllable.

8. The robot purifier of claim 6 , wherein the purifying part is capable of rotating 360 degrees horizontally and is capable of rotating vertically.

9. The robot purifier of claim 6 , wherein an air discharge hole is located in the purifying part, and
wherein a direction, in which the air is discharged through the air discharge hole, is changed to an upward direction or a downward direction when the purifying part rotates vertically.

10. The robot purifier of claim 7 , wherein a lower cover is located at an outer lower end of the purifying part, and a window lower cover is located at a portion of the center of the lower cover, which is connected to the driving part,
wherein the purifying part further comprises: a guide fan assembly which suctions the air inwards and is coupled to the lower cover,
wherein the guide fan assembly comprises a guide fan,
wherein an arc-shaped upward/downward motion gear is located in any one of the window lower cover and the guide fan, and
wherein the upward/downward motion gear is engaged with the pinion gear such that the purifying part is capable of rotating vertically.

11. The robot purifier of claim 8 , wherein the lower cover has a semispherical shape.

12. The robot purifier of claim 7 , wherein the air discharge hole is located on a front surface of the purifying part, and air suction holes are located on a left surface or a right surface, or both of the left surface and the right surface of the purifying part, and
wherein the air suction holes are cover filters which are provided in the guide fan assembly, the air discharge hole is a discharge grill which is provided in the guide fan assembly, and the discharge grill is located on the front surface of the purifying part.
