Description

[Detailed Description of the Invention] The present invention relates to a ceiling-embedded air conditioner.

In a conventional ceiling-embedded air conditioner of this type, as shown in FIG.
has an open lower end, and the width D of the lower end opening is larger than the width D of the blower assembly b (see Japanese Patent Laid-Open No. 14460/1983). Therefore, when attempting to remove the blower assembly b for repairs, inspections, etc., use the mounting screws d and d.
At the same time as removing the blower assembly b, the operator must climb down a ladder or the like while holding the blower assembly b, which is not only difficult but also dangerous. Another problem was that two workers were inevitably required.

In view of the above-mentioned problems, the present invention aims to improve workability and safety by allowing the blower assembly to be temporarily locked in the blower storage case during installation and removal work. In order to achieve this purpose, a part of the blower assembly is attached to the upper end of the inner surface of the blower storage case that is provided to install the blower assembly inside the main body, so that it will not be temporarily engaged when removed. It is characterized by a configuration in which a locking member is provided for locking.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A ceiling-embedded air conditioner according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

This ceiling-embedded air conditioner includes a main body 1 that is installed embedded in a state where it is suspended so as to face an opening 6 in a ceiling C using hanging bolts 5, 5 whose upper ends are fixed to a beam or the like above the ceiling C; The air chamber 2 is attached to the lower part of the main body 1 and exposed below the ceiling C.

Inside the air chamber 2, there is a main body 1 from the suction port 7.
A suction air passage 8 reaching the inner lower end and blowing air passages 10, 10 extending from the inner lower end of the main body 1 to the blow-off ports 9, 9 are defined by partition plates 11, 11.
Note that the reference numeral 21 is an air filter.

Further, the air chamber 2 has partition plates 11, 11
It is mounted by fixing the mounting ribs 22, 22 formed at the upper end to the lower end opening edge of the blower storage case 3 installed in the main body 1 with mounting screws 23, 23. rib 2
As shown in FIG. 3, 2 and 22 are upwardly inclined and protrude at an inclination angle θ (approximately 1 to 2 degrees) with respect to the horizontal. By doing this,
Both sides of the air chamber 2 are prevented from sagging downward in the installed state.

The blower storage case 3 has a wind outlet 1 on the top surface.
2 and is open at the bottom.

Inside this blower storage case 3, a blower assembly 4 consisting of a blower 13 and an angle-shaped fitting 14 for fixing the blower 13 is installed.
4 is removably arranged and fixed to the edge of the air outlet 12 on the upper surface of the blower storage case 3 by tightening it from below with mounting screws 15, 15.

The inside and outside of the blower storage case 3 include a suction air suction chamber 16 communicating with the suction air passage 8 and a blowing air discharge chamber 1 communicating with the blowing air passages 10, 10.
It is said to be 7.

A pair of heat exchangers 18, 18 are installed in the blown air discharge chamber 17 on both sides of the discharge side of the blower 13, facing each other. Further, a drain pan 20 is provided below each heat exchanger 18.

Furthermore, at the upper end of the inner surface of the blower storage case 3, a part of the blower assembly 4 (in this embodiment, the fitting 14) is located directly below the screw fixing point on one side of the fitting 14 of the blower assembly 4. 14) is provided with a horizontal locking member 19 for temporarily locking it during installation and removal.

Note that the locking member 19 only needs to be able to temporarily lock a part of the blower assembly 4, and does not necessarily have to be formed to have the same width over its entire length.

Here, the blower assembly 4 is installed and removed by removing the air chamber 2 to simplify the work. At this time, the operator must insert the blower assembly 4 from the air outlet 12 on the top surface of the blower storage case 3. The transportation and installation work must be carried out within a long and restricted space extending to the lower opening edge of the blower storage case 3, and it is not desirable from a physical and safety standpoint to perform such work all at once. In the case of the embodiment of the present invention, when removing the blower assembly 4,
As shown in FIG.
After locking the air blower assembly 4 in the upper position, it is only necessary to remove the other mounting screw 15, and the work can be done in stages, and the blower assembly 4 can be easily removed by one worker. When installing the blower assembly 4, conversely to the above, one end of the fixture 14 is locked onto the locking member 19, and the other end of the fixture 14 is secured with the mounting screw 1.
5, and then fix the one end side with the mounting screw 1.
5, the blower assembly 4 can be easily and safely installed by a single worker in the same manner as described above.

In the above embodiment, the locking member 19 is installed horizontally, but the present invention is not limited to this, and the locking member 19 is installed so as to be inclined upwardly toward the inside of the blower storage case 3. Of course, it may be installed. In this case, the fixture 14 is supported in line contact with the locking member 19.

Next, the effects of the ceiling-embedded air conditioner of the present invention will be described.

According to the present invention, a part of the blower assembly 4 is attached to the upper end of the inner surface of the blower storage case 3 provided to install the blower assembly 4 in the main body 1,
Locking member 19 for temporary locking during removal
Since the blower assembly (4) can be installed and removed in stages during service, it is possible to reduce the number of workers (from 2 to 1) and improve safety. This has the practical effect of significantly improving the results.
