Description

[Detailed Description of the Invention] The present invention relates to a ceiling-embedded air conditioner, and more particularly to an electrical component box mounting structure for a ceiling-embedded air conditioner.

In conventional ceiling-embedded air conditioners of this type, the main unit is embedded above the ceiling, so when servicing electrical components, the electrical component box a must be extended to the bottom of the ceiling as shown in Figure 6. If you don't withdraw money, it will be difficult to provide services. However, in this case, in order to pull out the electrical component box a downward from the main body 6,
It is necessary to provide the electrical connection wiring c to be connected to the electrical connection line c with a considerable length c'. Therefore, a storage space for the wiring is required for the slack, and when the electrical component box a′ that has been pulled out has to be put back into its original position, the wiring must be stored while doing so, which creates work difficulties. There was a problem.

This invention solves the above problems and has a simple structure.
Moreover, the purpose is to provide an electrical component box mounting structure with excellent workability during service. is removably arranged and fixed, and an electrical communication wiring introduced horizontally is connected to the lower end of one side of the electrical component box through an insertion hole provided in the outer case, and the electrical communication wiring is connected to the lower end of one side of the electrical component box. The present invention is characterized by a configuration in which the electrical component box can be freely rotated around the center.

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 5.

This ceiling-embedded air conditioner includes a main body 1 that is installed embedded in a beam or the like above a ceiling 4 with hanging bolts 5, 5 so as to face a ceiling opening 6, and a main body 1 that is installed at the bottom of the main body 1. and an air chamber 2 exposed below the ceiling 4.

Inside the main body 1, a blower storage case 3 is installed which has an air outlet 7 on the upper surface and is open at the bottom.

Inside the blower storage case 3, a centrifugal blower 8 is detachably attached via a fitting 9.

The inside and outside of the blower storage case 3 are defined as a suction air passage 10 and a blowing air passage 11.

Blowing air passages 11 on both sides of the discharge side of the blower 8
A pair of heat exchangers 12, 12 are installed facing each other.

A drain pan 13 made of integrally molded synthetic resin is provided below each heat exchanger 12.

As shown in FIGS. 2 and 5, a lead wire 15 is placed at a proper place in the drain pan 13 to hold the lead wire 15 to the blower driving motor 14.
A hole 16 having a notch 17 slightly smaller than the wire diameter is formed. Therefore, the lead wire 15 is in the notch 1.
7 and is force-fitted into the hole 16,
Lead wires can be held securely without the need for clasps or the like.

Further, an electrical component box 19 is removably arranged and fixed on the inner surface of the outer case 18 of the main body 1, supported by a cover 22 which is detachable from the main body 1 side.

As shown in FIGS. 3 and 4, at the corner of the electrical component box 19, that is, at the lower end of one side, an electrical connection wiring 21 is introduced horizontally through an insertion hole 20 provided in the outer case 18. is connected.

The electrical communication wiring 21 is fixedly held at the corner by a clamp member 27 that is fixed to one side wall 29 of the electrical component box 19 with a screw 28, and after its tip side is bent into an L shape, the tip wiring portion is bent. Terminal board 26
are connected to each.

The electrical communication wiring 21 is inserted into the insertion hole 20,
It has enough rigidity to serve as the center of rotation of the electrical component box 19. In order to ensure this rigidity, a sleeve-shaped reinforcing member may be provided on the electrical communication wiring 21.

In such an electrical component box mounting structure, when the air chamber 2 and cover 22 are removed, the electrical component box 19 rotates about 90 degrees in the direction of arrow A about the electrical connection wiring 21 as shown in FIG. Therefore, the inside of the electrical component box 19 is exposed below the main body 1, making servicing easier. on the other hand,
After the service is completed, the electrical component box 19 can be easily stored in the main body 1 by simply rotating the electrical component box 19 in the direction of arrow B in the opposite direction.

In the drawings, reference numeral 23 is an air inlet, 24 is an air outlet, and 25 is an air filter.

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

According to the present invention, an electrical connection is introduced horizontally to the lower end of one side of the electrical component box 19 provided on the inner surface of the outer case 18 of the main body 1 through the insertion hole 20 provided in the outer case 18. Since the wiring 21 is connected and the electrical component box 19 can be rotated around the electrical connection wiring 21, the workability when taking out and storing the electrical component box 19 is significantly improved, and it is possible to There is a practical effect that there is no need to prepare a sag for connection wiring as in the example, there is no need to provide a storage space for the sag, and space can be used effectively.

Furthermore, since there is no need to shorten the metal distribution line or provide a hinge, there is also the advantage that costs can be reduced.
