An air circulation fan 12 is disposed in the main body 7 (see FIGS. 1 and 3). Although two fans are provided in the illustrated embodiment, one fan may be provided, or three or more fans may be provided.

The fan 12 is a motor 13 in the illustrated embodiment.
And a blade body 14 rotated by the motor. The blades are set, for example, to flow air from the first duct 5 to the second duct 6.

The motor 13 is supported on the inner wall of the main body 7 by a plurality of support rods 15.

The lower end of the first duct 5 is fitted into the first cylindrical body 8 of the main body, and the upper end of the second duct 6 is fitted to the second cylindrical body 9.
Is fitted inside.

A first air port 1 is provided at an upper end of the first duct 5.
6 is provided, and a second air port 17 is provided at a lower end of the second duct 6. The first air port 16 is arranged near the ceiling 2a, and the second air port 17 is arranged near the floor 2b.

The first duct 5 and the second duct 6 are movable with respect to the first cylinder 8 and the second cylinder 9 by adjusting means 18, respectively. These adjusting means are the first cylinder 8
And a vertically extending slit 19 provided in the second cylindrical body 9 and a bolt 20 screwed into the first duct 5 and the second duct 6 through these slits. These adjusting means are provided on both sides of the first duct 5 and on both sides of the second duct 6, respectively. Accordingly, when the bolt 20 is loosened, the first duct and the second duct can move in the vertical direction, and when the bolt 20 is tightened, the first and second ducts can be fixed to the base. In addition, the first and second ducts can be fixed to the wall surface by an arbitrary fixing means 21 if necessary.

The mounting means 11 for mounting the base on the wall surface is screwed into the wall surface 3 and fitted into a hole 7a formed in the main body 7, and a tightening screw 2 screwed into the screw rod.
It consists of three. Therefore, when the fastening screw 23 is loosened, the base can be rotated with respect to the wall surface, and when the fastening screw is tightened, the base can be fixed to the wall surface.

The use state is briefly described as follows. First, the screw rod 22 is screwed into a predetermined wall surface. The base is then attached to the screw rod 22 by inserting the screw rod into the hole 7a of the main body 7 and then screwing the tightening screw 23 into the screw rod 22. Next, a first duct 5 and a second duct 6 are respectively attached to the first cylinder 8 and the second cylinder 9 of the base.
And the bolts 20 are screwed into the first duct and the second duct through the slits 19, respectively, so that the first duct and the second duct are fixed to the base.
At this time, the first air port 16 of the first duct is located as close as possible to the ceiling 2a, and the second air port 1 of the second duct is
7 is located as close to the floor 2b as possible. Next, the first duct and the second duct are fixed to the wall surface using fixing means 21 as necessary. When the fan is driven in this state, air near the ceiling is introduced into the first air port 16, and this air is supplied to the first duct 5, the air circulation hole of the main body,
The air is blown out from the second air port 17 through the second duct 6.
In this case, warm air near the ceiling can be supplied to the floor, which is particularly suitable for heating.

In the case of cooling, in order to supply cold air near the floor near the ceiling, the fixing means of the first duct and the second duct are released, and the bolt 20 is loosened to release the first duct and the second duct. The second duct is reduced and then the clamping screw 22 is loosened and the base 4 is rotated so that the first duct 5 is located below and the second duct 6 is located above. Next, the base, the first and second ducts are fixed as described above. In this way, cool air near the floor is introduced into the first air port 16, and this air flows from the second air port 17 through the first duct, the air circulation hole, and the second duct to the ceiling. Blow out close.

One end of the second duct 6 is slidably inserted into b. In this embodiment, the first duct and the first cylinder and the second duct and the second cylinder are simply inserted and are not fixed by any arbitrary attaching means. Instead, the first and second ducts are fixed to the wall by the fixing means 21. In this case, it is preferable that the fixing means be a double-sided tape, for example, since the mounting becomes easy. In this embodiment, the fan is mounted on, for example, a shelf provided on the inner surface of the second cylindrical body 4b. The fan can be inverted after separating the first and second cylinders. Therefore, it can function for cooling and for heating.

In the embodiment shown in FIG. 5, the fan 12 is rotatably mounted on the base 4 and is freely reversible by reversing means or a knob 30. In this case, the fan is locked at a predetermined position by lock means (not shown).

In the above embodiment, the first and second ducts, the base and the like can be made of plastic.
