Claims

[Claim for Utility Model Registration] A blower with a variable air blowing volume is provided, and includes a concentrated mode in which air is blown toward the passenger, and a concentrated mode in which the air is diffused at a speed lower than the air blowing speed in the concentrated mode. an air blowing means operable by switching between a diffusion mode and a diffusion mode for blowing out air; a temperature setting means for setting the temperature in the vehicle interior to a desired value; a temperature detection means for detecting the temperature in the vehicle interior; and a temperature setting means. steady state detection means for detecting a steady state in which the absolute value of the temperature difference between the temperature set in and the temperature detected by the temperature detection means is equal to or less than a first preset tolerance value; a first command giving means for giving a command to the air blowing means to set the air blowing means to the concentration mode on the condition that the air blowing means is not detected; a second command giving means for giving a command to the air blowing means to set the air blowing mode to the diffusion mode on the condition that the air blowing mode is equal to or less than a second tolerance value which is smaller than the first tolerance value; and when the steady state is detected, the absolute and third command giving means for giving a command to the air blowing means to cause the air blowing means to perform an operation of alternately switching between the concentration mode and the diffusion mode, provided that the value exceeds the second tolerance value.
