<p>PURPOSE:To make an efficient use of heat by a simple apparatus which is designed to circulate air at a lower part in a room to be air-conditioned to an upper part of the room through a flexible pipe connected to a fan. CONSTITUTION:There is at first prepared a strip-like member 4, which is formed at one side thereof with an outwardly opened recess 6 and at the other end with a projection 7 that can be inserted into the recess 6 to a desired fitting depth. From the strip-like member 4, a flexible pipe 1 is fabricated by winding the member 4 into a spiral form and fitting the projection 7 of one spiral turn of the member 4 into the recess 6 of the adjacent turn to a desired fitting depth. Short end pipes 8, 9 are fitted respectively to the base and top ends of the pipe 1, and the base end 8 is connected to a fan 2 disposed at a lower part of the room while the top end 9 is opened at an upper part of the room. With such a simple arrangement, it is enable to make an efficient use of heat by circulating air in the room to be air-conditioned.</p> |
