DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below as examples based on the attached drawings. 1 to 4
As shown by, 1 is a case body embedded in the ceiling surface,
Reference numeral 5 denotes a decorative panel which is mounted on the lower surface of the case body 1 and has a suction port 2 at the center, and an outlet 4 around which a wind direction changing plate 3 is rotatably supported by a support shaft 3a. Numerals 7 and 7 denote a fan motor and a blower fan having a vertical drive shaft facing the suction port 2 in an air passage connecting the suction port 2 and the blowout port 4 formed in the case body 1. The fan motor 6 and the blower fan 7 constitute a blower. 8 is a heat exchanger provided in the air passage.

A diffuser 9 held at the outlet 4 so as to be able to protrude and retract along the inner peripheral outer surface of the outlet 4, a driving unit 10 linked to the diffuser 9 and driving the diffuser 9, and one end of the diffuser 9;
11b is rotatably supported on the decorative panel 5 and the other end 11a
Is linked to the lower end of the diffuser 9 and the outlet 4
When the wind direction changing plate 3 is turned to the side blowing position,
As shown in FIG. 2, the driving unit 10 accommodates the diffuser 9 inside the air outlet 4, and rotates the auxiliary wind direction changing plate 11 upward in conjunction with the diffuser 9 to move the diffuser 9 upward. 11 is not substantially parallel to the wind direction changing plate 3,
When the wind direction changing plate 3 is turned to the lower blowing position, as shown in FIG. 3, the diffuser 9 is protruded to a lower portion of the air outlet 4 by the driving unit 10, and the auxiliary wind direction is interlocked therewith. The configuration is such that the change plate 11 is rotated downward so that the auxiliary wind direction change plate 11 is substantially parallel to the wind direction change plate 3, thereby solving the above-described problems in the related art. For example, during a cooling operation, a part of the cool air blown out from the outlet 4 is prevented from falling down. On the other hand, for example, during a heating operation, the warm air is accurately directed from the outlet 4 in a vertical direction. It becomes the structure which was able to blow out to.

Further, a linking portion a for linking the other end 11a of the auxiliary wind direction changing plate 11 to a lower end portion of the diffuser 9 is provided at a plurality of locations in the longitudinal direction of the diffuser 9 and the auxiliary wind direction changing plate 11. Thereby, the up and down movement of the diffuser 9 is accurately linked to the other end 11a of the auxiliary wind direction changing plate 11, and the auxiliary wind direction changing plate 11 is smoothly linked to the one end 11b as a center. The structure is such that it can be rotated.

Further, a driving unit 10 linked to and driving the diffuser 9 comprises a driven gear 9a provided in the diffuser 9 and a driving gear 10a meshed with the driven gear 9a.
And a drive motor 10b for driving the drive gear 10a, whereby the diffuser 9 and the auxiliary wind direction changing plate 11 linked thereto are rotated by the wind direction changing plate 3. In this structure, the air can be accurately driven in synchronism with the above, and the air blown out from the air outlet 4 can be accurately sent out in the horizontal or vertical direction.

Further, since the driven gear 9a is formed integrally with the diffuser 9, the dimensional shape can be accurately finished and the configuration is advantageous in terms of cost.

Further, guides 5a are provided on both sides of the air outlet 4 and extend substantially vertically, and holding portions for holding the diffuser 9 so as to be able to protrude and retract are provided on both sides of the diffuser 9 corresponding to the guides 5a. The structure includes a slide portion 9b formed continuously, thereby providing a structure in which the diffuser 9 can be accurately and smoothly protruded and retracted.

Further, the guide 5a is constituted by grooves formed continuously on both sides of the outlet 4.
By the guide 5a having a simple configuration, the sliding portion
9b can be slid accurately and smoothly.

With the above construction, as shown in FIGS. 1 to 4, the diffuser 9 held at the outlet 4 so as to be able to protrude and retract along the inner peripheral outer surface of the outlet 4, and the diffuser 9 is linked to the diffuser 9. And a driving part 10 for driving the same, one end 11b is rotatably supported on the decorative panel 5, and the other end 11a is connected to the lower end of the diffuser 9 to form one end of the outer periphery of the outlet 4. Auxiliary wind direction change plate 11 constituting a part is attached,
When the wind direction changing plate 3 is rotated to the horizontal blowing position, the diffuser 9 is housed inside the air outlet 4 by the driving unit 10 and the auxiliary wind direction changing plate 11 is rotated upward in conjunction with the diffuser 9. When the auxiliary wind direction changing plate 11 is turned substantially parallel to the wind direction changing plate 3 and the wind direction changing plate 3 is turned to the lower blowing position, the driving unit 10 moves the diffuser 9 to the air outlet 4. While projecting to the lower part, in conjunction with this, the auxiliary wind direction changing plate 11 is rotated downward,
Since the auxiliary wind direction changing plate 11 is made substantially parallel to the wind direction changing plate 3, the above-described problem in the prior art can be solved. While part of the cool air blown out from the cool down, for example, during heating operation,
A ceiling-embedded air conditioner capable of accurately blowing hot air from the outlet 4 in the vertical direction is provided.
