DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With the above-described structure, an air conditioner with an embedded ceiling is easy to assemble and has a small number of parts.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the present invention shown in FIGS. 1 to 8 will be described. A suction port 11 is provided at the center of the decorative panel 1 installed downward on the ceiling surface, four outlets 2 facing different directions are provided at four sides of the outer peripheral portion, and a wind direction plate 3 is provided at the outlet 2, Filter 12 on top of mouth 11
Is blown up by a blower fan 14 driven by a motor 13.
A heat exchanger 15 is provided on the outer periphery of the blower fan 14. The blower fan 14 filters the room air from the suction port 11 through the filter 12 and sucks the air. The exchanged air is blown out of the outlet 2 with the wind direction adjusted by the wind direction plate 3. Rotating shafts 3a formed at both ends of a wind direction plate 3 formed of a resin such as ABS are rotatably supported by bearings formed on the back surface of the decorative panel 1 on both sides of the air outlet 2. At each of the three corner portions 1a of the decorative panel 1, a D-cut 3 is provided at each of the tips of the rotating shafts 3a of the two wind direction plates 3 adjacent at an angle of 90 °.
b is formed. A cylindrical sheet material such as a vinyl chloride resin was formed into a hollow bellows-shaped tube 4 by blow molding, and circular shaft holes 4b equivalent to or slightly larger than the rotation shaft 3a were formed at both ends of the bellows-shaped tube 4. A cylindrical portion 4a is provided,
The shaft hole 4b is inserted into the rotating shaft 3a, and the cylindrical portion 4a
Is bound by a binder 5, the cylindrical portion 4a is crushed, and the D cut 3b is prevented from rotating and is fixed. At the three corners 1a of the decorative panel 1,
A rib 6 having a U-shaped groove 6a slightly larger than the outer shape of the bellows-shaped tube 4 is integrally formed.
The bellows-shaped tube 4 is fitted into the V-shaped groove 6a. The bellows-like tube 4 is supported by the ribs 6 to connect the tip of the rotating shaft 3a of the two wind direction plates 3 adjacent to each other at the 90 ° angle without twisting, so that the rotating power can be reliably provided. introduce. At one of the three corners 1a of the decorative panel 1, D-cuts 8c are formed at both ends of a cylindrical body 8 protruding a cam connecting rod 8b having a spherical body 8a formed at a tip thereof. The rotating shaft 3a of the wind direction plate 3 adjacent to the corner portion is connected with the bellows-shaped tube 4, respectively, and the middle of the bellows-shaped tube 4 is connected to the decorative panel 1.
The cam connecting rod 8 is rotatably supported by the rib 6.
By engaging the spherical body 8a at the end of b with the groove 9a of the groove cam 9 and driving the groove cam 9 by the motor 10, the cam connecting rod 8b swings and the bellows tube 4 The connected wind direction plate 3 rotates. In addition, since the shaft hole 4b of the bellows-shaped tube 4 is circular, D
Even if the phase of the cut 3b and the phase of the D-cut 8c of the cylindrical body 8 do not match, it can be adjusted during assembly.

Next, another embodiment shown in FIG. 9 will be described. The shape of the shaft hole 4b formed in the cylindrical portion 4a is different from that of the embodiment. A description will be given by taking the rotating shaft 3a as an example. By making the shape of the shaft hole 4b formed in the cylindrical portion 4a a D-cut shape corresponding to the D-cut 3b of the rotating shaft 3a, it is ensured only by inserting the rotating shaft 3a into the shaft hole 4b. Power can be transmitted to the motor. In addition,
Also in this example, if the outer periphery of the cylindrical portion 4a is bound with a binder or the like, it is possible to more reliably prevent the cylindrical portion 4a from coming off.

Next, another embodiment shown in FIG. 10 will be described. The embodiment refers to the rotation axis 3 of the wind direction plate 3.
a and the method of locking the cylindrical body 8 and the bellows-shaped tube 4 are different. A description will be given by taking the rotating shaft 3a as an example. At the tip of the rotating shaft 3a of the wind direction plate 3, two columnar portions 7b projecting in the axial direction of the rotating shaft 3a, and a projecting portion 7a projecting from the columnar portion 7b in the outer circumferential direction of the rotating shaft. Are integrally formed. On the other hand, a concave portion 4c in which the locking claw 7 is engaged
Are formed at two locations facing each other. By inserting the locking claw 7 into the cylindrical portion 4a and pressing the protruding portion 7a of the locking claw 7 from the outer periphery of the cylindrical portion 4a, the locking claw 7 bends inward due to the elasticity of the columnar portion 7b. , The cylindrical portion 4a is
a. The projection 7a of the locking claw 7 is
When the protrusion 7a is inserted to the position c, the protrusion 7a is hooked and locked by the recess 4c due to the elasticity of the columnar portion 7b. The locking claw 7 is hooked on the concave portion 4c, thereby preventing the bellows-shaped tube 4 from coming off from the rotating shaft 3a and transmitting the rotating power.
