Abstract

A gas compressor includes a main body portion including a compression unit configured to compress gas, an air blowing unit, and a drive unit configured to drive the compression unit and the air blowing unit, a cover portion covering at least a part of the main body portion and having an air vent through which air flows from the air blowing unit, and a handle portion having a gripping portion. The air vent faces a rotation axis direction of a rotation member of the air blowing unit which is rotated by being driven by the drive unit, and the handle portion includes a protective portion facing the air vent and being apart from the air vent.

Claims (27)

1. A gas compressor comprising:

a main body portion including:

a compression unit configured to compress gas, the compression unit comprising cylinders including pistons;

an axial fan; and

a motor configured to drive the compression unit and the axial fan;

a cover portion covering at least a part of the main body portion and having an air vent through which air flows; and

a handle portion having a gripping portion,

wherein the air vent faces a rotation axis direction of a rotation member of the axial fan which is rotated by being driven by the motor,

wherein the handle portion includes a protective portion facing the air vent and being apart from the air vent, and

wherein the protective portion includes an upper protective portion extending upward to an upper surface portion of the cover portion to face and cover an upper portion of the air vent.

2. The gas compressor according to claim 1 ,

wherein the protective portion includes a side protective portion facing a front portion of the air vent, and

wherein the upper protective portion and the side protective portion are apart from the air vent.

3. The gas compressor according to claim 1 , wherein an upper end side of the protective portion includes an upper end portion configured to be fixed to the upper surface portion of the cover portion, and a lower end side of the protective portion includes a lower end portion configured to be fixed to the main body portion.

4. The gas compressor according to claim 1 , wherein the protective portion includes two protective portions, the two protective portions being located a distance from each other, a length of the distance being substantially the same as a width of the air vent.

5. The gas compressor according to claim 1 ,

wherein the cover portion includes a first side portion on a first side of the rotation member, and a second side portion on a second side of the rotation member, the first and second side portions facing the rotation axis direction, and

wherein the protective portion includes two protective portions, a first protective portion of the two protective portions is disposed on the first side portion, and a second protective portion of the two protective portions is provided on the second side portion of the cover portion.

6. The gas compressor according to claim 5 , wherein the handle portion includes a coupling portion that covers and is coupled with at least a part of the upper surface portion of the cover portion.

7. The gas compressor according to claim 5 , wherein the handle portion is coupled with the cover portion with a coupling member that covers at least a part of the upper surface portion of the cover portion.

8. The gas compressor according to claim 1 further comprising one or more tanks configured to store the gas compressed by the compression unit,

wherein the rotation axis direction of the rotation member is parallel to a longitudinal direction of the one or more tanks.

9. The gas compressor according to claim 1 , wherein the cover portion covers a side face of the main body portion.

10. The gas compressor according to claim 4 , the gripping portion is disposed between the two protective portions.

11. The gas compressor according to claim 1 , the protective portion includes a first portion extending along the rotation axis direction of the rotation member and a second portion extending downward from an end portion of the first portion.

12. The gas compressor according to claim 11 , the gripping portion laterally extends from the end portion of the first portion.

13. The gas compressor according to claim 1 , wherein the upper protective portion extends obliquely upward, relative to a horizontal direction, to the upper surface portion of the cover portion.
