Abstract

PURPOSE:To perform individual and easy exchange of a flap by a method wherein a spherical protrusion is formed on either the rotary shaft of the flat or a joint to convert rotational movement of a gear into reciprocating movement, and a part engaged with the protrusion is formed in the other. CONSTITUTION:In exchange of only one of flaps 23, when two screws of a seal material 25 positioned facing the flap 23 are first removed and the seal material 25 is removed, a mounting tool 32 is exposed. Therefore, the knobs of support tools 31 on both sides are grasped to dislock a projection 35 from the mounting tool 32, and a support tool 31 is removed from the mounting tool 32. When a projection 56 is disengaged from an engaging part 59 of a rotary shaft 29 and rotary shafts 29 and 30 are removed from the flap 23, the flap 23 is easily removed from the mounting tool 32. By preceding a reverse work to the above, mounting of the flap 23 can be facilitated. Further, since the projection 56 of a joint 46 is formed in a spherical shape, wear between the engaging part 59 and the projection 56 and the generation of abnormal noise are suppressed, and resistance due to wear between the engaging part 58 and the projection 56 can be reduced.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a ceiling-embedded air conditioner.

(b) Conventional technology The conventional technology for air conditioners is Utility Model Application No. 63-12393.
There is an air conditioner described in Publication No. 7, in which the main body of the air conditioner is installed inside the ceiling, and a decorative panel is installed on the lower surface of the main body to close the opening in the ceiling. In some cases, the flaps provided at the air outlet of this decorative panel are connected by a joint, and a plurality of flaps are moved by one motor.

(8) Problems to be Solved by the Invention Some of the air conditioners mentioned above have hair flocked on the surface of the flap to prevent condensation during cooling operation.
If the flap becomes contaminated with dust in the air, it will be necessary to replace it. Furthermore, in the air conditioner mentioned above, the connection between the flap and the joint is such that it cannot be easily removed, so when removing and replacing only one of the multiple flaps, it takes a lot of time and effort. there were.

The present invention provides an air conditioner in which flaps can be replaced individually and easily.

14) uses a turbo fan (
11); (15) is a drain pan formed of polystyrene foam into an angular ring shape having an inner rising portion (15a) and an outer rising portion (15b);
16) is a plate-fin type heat exchanger arranged in an annular manner on the discharge side of the turbo fan (11) so as to surround this fan.

(17) is a heat insulating material wrapped around the circumferential surface of the main body (2), and (21) is an air guiding portion that guides the air heat exchanged in the heat exchanger (16) to the outlet (4). , (22) is a hanging bolt for fixing the main body (2) to a ceiling beam with a hanging tool,
<24) is a filter attached to the downstream side of the suction grille (9), and (23) is a flap.

FIG. 2 is a perspective view of a decorative panel according to the present invention, and FIG. 3 is a plan view of a sealing member. A sealing member (25) is formed to face each outlet (4), and is mainly made of polystyrene foam, and the surface that contacts the main body (2) is provided with foamed urethane. (26) is a housing part for a motor that drives the flap (23), (27) is a housing part for a fixture to which the flap is attached, and (28) is a hole for screwing.

FIG. 4 is a perspective view showing the relationship between the flap, the support, and the attachment. (29) (30) is a rotating shaft attached to the flap (23), (31) is a support that supports this rotating shaft (29), and (32) is a fixture that is attached to the opening (33). It is. Although not shown, the same support as this support (31) is also attached to the other opening (34). FIG. 5 is a perspective view of another support.

(35) is a locking protrusion formed on the support (31);
(36) is a knob formed integrally with this protrusion, (37
) is a rib formed to generate sufficient elastic force in this knob. (38) are supports provided at two locations farthest from the motor, that is, on the diagonal side, and these supports include stoppers (39) to prevent the rotation axis of the flap (23) from shifting or coming off. is formed.
