Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention relates to a ceiling-mounted air conditioner suspended and fixed to a ceiling.

(B) Conventional technology In a ceiling-mounted air conditioner that is installed in a high place indoors, when the electrical equipment box is taken out from the bottom opening of this main body and the electrical equipment box is service-checked, the length of the lead wire connected to the electrical equipment box Since there is a limit to the size, the operator has to carry the electrical equipment box with one hand, which is a drawback that it is difficult to work.

For this reason, an air conditioner in which the electrical equipment box is hooked on the lower surface of the main body during service inspection is presented in Japanese Utility Model Publication No. 62-2792.

(C) Problems to be solved by the device In the air conditioner presented in the above publication, the position where the electrical equipment box is hooked is determined, so if there is furniture such as a shelf below this electrical equipment box, this furniture will be an obstacle. , There was a problem that it was difficult to carry out service inspection of the electrical equipment box.

The present invention provides an air conditioner that solves these problems.

(D) Means for solving the problem In this proposal, flange pieces are provided on both side edges of the lower surface opening of the air conditioner main body, and the flange pieces are slidable from the lower surface opening to the upper part of the electrical equipment box housed in the main body. It is provided with an overhanging piece that is hooked to.

(E) Action The electrical equipment box is housed in the main body through the bottom opening and fixed in place. When servicing the electrical equipment box, if the electrical equipment box is removed and lowered, the electrical equipment box is exposed below the opening and the overhanging piece catches on the flange piece of the opening to stop. If you move it to the position, you can easily perform service inspection work on the electrical equipment box.

(F) Embodiments Referring to the drawings, FIG. 1 is a perspective view of a ceiling-mounted air conditioner, in which a lower panel (2) of a main body (1) has an air suction nozzle
(3) and the service panel (4) are provided, and air outlets are provided on the front panel (5) and both side panels (6) of the main body (1), respectively.
(7) and (8) are provided.

Figure 2 shows bottom panel (2), front panel (5) and both side panels
In the perspective view of the ceiling-mounted air conditioner with (6) removed,
The air blower (9), the heat exchanger (10) and the drain van (not shown) are built in the inside, and the opening for the air suction port where the air suction grille (3) and the service panel (4) can be attached. (1
A pair of flange pieces (13) are provided along the longitudinal direction on both side edges of 1) and the service opening (12).

(14) is an electrical equipment box which is housed in the main body (1) through the openings (11) and (12). As shown in FIGS. 3 and 4, the air intake opening (1
The concave portion (15) is formed as a suction passage for indoor air to be sucked into the blower (9). And, a pair of flange pieces (16) slidably hooked to the pair of flange pieces (13) on the upper part of the electrical equipment box (14), and a pair of flange pieces on the lower part of the electrical equipment box (14).
A pair of mounting pieces (17) screwed from below to (13) and a lid that is removed when servicing the electrical parts inside the electrical box (14).
(18) and are provided, and the narrow lower part (1
9) is designed to be used as a handle that an operator holds with one hand.

Moreover, the flange portion (20) of the service panel (4) is cut out along the opening (11) in connection with the provision of the recessed portion (15) in the electrical equipment box (14), so that the cutout portion (21) is formed. A large amount of intake air is secured, and the indoor air drawn from the opening (B) near the blower (9) is blown by the blower (9) as shown by the solid line arrow in Fig. 4.
The room air sucked from the upper part of the suction port (22) of the electric fan and from the opening (C) farther from the blower (9) is shown by the broken line arrow in FIG. ), The flow path resistance is small because it is sucked from the lower part of the suction port (22) of the blower (9), and a large intake air amount is secured as described above under low noise. .

The air conditioner of the present invention is configured as described above. From the state shown in FIG. 3, hold the lower part (19) of the electrical equipment box (14) with the left hand and push the electrical equipment box (14) upward to attach the mounting piece (17). The hole (23) of the flange piece (13) and the hole (24) of the flange piece (13) are screwed from below with the right hand.
As shown in the figure, the electrical equipment box (14) is installed in the main body (1), and when the air intake grill (3) and service panel (4) are installed in the openings (11) and (12), the The air conditioner is completed as shown in the figure.

Then, by operating the air conditioner, the indoor air is sucked from the air suction grille (3), and is blown out from the air blower (9) and the heat exchanger (10) in order, and is blown out from the air outlet (7) to cool the room. During this cooling operation, the electrical equipment box (14) is brought into contact with the sucked indoor air to be cooled, so that the temperature does not rise to an abnormal temperature.

When inspecting such electrical box (14) for service, air intake grill
After removing (3) and the service panel (4), use the left hand to control the electrical box.
While holding the lower part (19) of (14), attach the mounting piece (17) to the flange piece.
When it is removed from (13) and the electrical box (14) is lowered, the protruding piece (16) is caught by the flange piece (13) and the electrical box (14) opens (11) (12).
It stops in the state of being exposed downward. Then, after sliding the projecting piece (16) on the flange piece (13) in the direction of the solid arrow A shown in FIGS. 2 and 3, the electrical equipment box (14) is shifted to a desired position, and then the electrical equipment box (14) If the lid (18) of 14) is removed, the service inspection of the electric parts in the electrical box (14) can be performed.

Also, when checking the service of the blower (9) and other parts, an electrical box
If (14) is an obstacle, the electrical equipment box (14) may be moved to a desired position as described above.

(G) Effect of the Invention According to the present invention, when the electrical equipment box is removed and lowered during service inspection of the electrical equipment box, the electrical equipment box is exposed below the opening on the bottom surface of the air conditioner body, and the overhanging piece becomes the opening flange piece. Since the projecting piece can be caught and stopped and the protruding piece can be slid on the flange piece, it is possible to shift the electric equipment box to a desired position and easily perform service inspection.
