What is claimed is: 1. An outdoor unit of an air conditioner, comprising: a housing including a bottom surface, a side surface, and an upper surface; an outdoor heat exchanger arranged along the side surface of the housing; a blowing fan arranged on the upper surface of the housing; a bell mouth arranged around the blowing fan; a fan guard provided to cover an upper portion of the blowing fan; and a height changing member configured to change a height of the fan guard with respect to the blowing fan, wherein the fan guard includes a support frame to be fitted onto the bell mouth, the height changing member includes multiple first raised portions formed at a predetermined interval along a circumferential direction of the bell mouth on a side surface of the bell mouth, and second raised portions formed to protrude downward from a lower side of the support frame and formed at an interval equal to that of the first raised portions along a circumferential direction of the support frame, and the first raised portions and the second raised portions are configured such that each second raised portion is arranged between adjacent ones of the first raised portions or arranged on a corresponding one of the first raised portions. 2. An outdoor unit of an air conditioner, comprising: a housing including a bottom surface, a side surface, and an upper surface; an outdoor heat exchanger arranged along the side surface of the housing; a blowing fan arranged on the upper surface of the housing; a bell mouth arranged around the blowing fan; a fan guard provided to cover an upper portion of the blowing fan; and a height changing member configured to change a height of the fan guard with respect to the blowing fan, wherein the fan guard includes a support frame to be fitted onto the bell mouth, the height changing member includes multiple first raised portions formed at a predetermined interval along a circumferential direction of the bell mouth on a side surface of the bell mouth, and second raised portions formed to protrude downward from a lower side of the support frame and formed at an interval equal to that of the first raised portions along a circumferential direction of the support frame, the first raised portions and the second raised portions are configured such that each second raised portion is arranged between adjacent ones of the first raised portions or arranged on a corresponding one of the first raised portions, each first raised portion includes a first slope as a rising slope along the circumferential direction of the bell mouth from a second side of another one of the first raised portions adjacent to a first side of the each first raised portion, each second raised portion includes a second slope as a slope parallel with the first slope, and the first raised portions and the second raised portions are configured such that each second raised portion is, in association with rotation of the fan guard, guided by the first slope and the second slope to move onto a corresponding one of the first raised portions.
