FAN
First Claim
1. A fan, comprising:
- a motor portion having a shaft which rotates by taking a central axis as a center,an impeller portion configured at a side of the motor portion along an axial direction and connected with the shaft, andan upper cover portion configured at a radial outside of the impeller portion and in which the impeller portion is accommodated,the upper cover portion comprising an outside air guide wall portion located at a radial outside of the impeller portion, an inside air guide wall portion located at a radial inside of the outside air guide wall portion and having an air suction port which penetrates in the axial direction, and a plurality of connecting portions connected with the outside air guide wall portion and the inside air guide wall portion,characterized in thatthe impeller portion has a side wall portion which rotates by taking a central axis as a center, an upper wall portion located at a side of the side wall portion along the axial direction and extending along a radial direction, a plurality of wing portions extending along radially outside from the side wall portion, and a plurality of pressurizing wings configured at a side of the upper wall portion along the axial direction.

Abstract
A fan includes a motor portion having a shaft which rotates by taking a central axis as a center, an impeller portion configured at a side of the motor portion along the axial direction and connected with the shaft, and an upper cover portion configured at a radial outside of the impeller portion and in which the impeller portion is accommodated, the upper cover portion including an outside air guide wall portion located at a radial outside of the impeller portion, an inside air guide wall portion located at a radial inside of the outside air guide wall portion and having an air suction port which penetrates in an axial direction, and a plurality of connecting portions connected with the outside air guide wall portion and the inside air guide wall portion, characterized in that the impeller portion has a side wall portion which rotates by taking a central axis as a center, an upper wall portion located at a side of the side wall portion along the axial direction and extending along a radial direction, a plurality of wing portions extending along radially outside from the side wall portion, and a plurality of pressurizing wings configured at a side of the upper wall portion along the axial direction. With the structure of the fan, the air suction wind volume of the air suction port of the fan can be improved, and the exhaust efficiency can be increased.
