PURPOSE: To obtain a structure having one suction port, two blowing parts and two fans, low in noise, high in efficiency and capable of carrying out various controls by a method wherein a partition position control means is proided to vary a partition position of a partition mechanism in response to its operating state. CONSTITUTION: There are provided one suction port 2 for sucking indoor air, an upper blowing port 3 and a lower blowing port 4 for blowing out the sucked air from the upper position and the lower position than that of the suction port 2, respectively. An upper fan 9 is arranged between the suction port 2 and the upper suction port 3. A lower fan 10 is arranged between the suction port 2 and the lower blowing port 4 and the indoor air sucked from the suction port 2 is guided by a flow passage passing through an upper fan 9 and reaching the upper blowing port 3 and a passage passing through a lower fan 10 and reaching the lower blowing port 4. Then, there are provided a partition plate 11 arranged to enable the partition position to be variable and a partition position control means variably changing the partition position of the partition plate 11 in response to an operating state. |
