BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to a bell mouth holding structure for a ceiling-embedded air conditioner.

[0002]

2. Description of the Related Art A ceiling-embedded air conditioner according to a conventional example is described with reference to FIG. 5 and FIG.
A fan 2 and a heat exchanger 3 that surrounds the fan 2 are disposed inside, the lower surface of the heat exchanger 3 is contacted, and the open surface is covered with a shielding member 4,
The shielding member 4 is provided with a suction port 5 facing the fan 2 and a discharge port 6 between the main body 1 and the suction port 5 covered with a bell mouth 7, and one end is fixed to the lower end of the main body 1. The shielding member 4 is pressed against the heat exchanger 3 by the four support plates 9 whose other ends are supported by the support rods 8 and the bell mouth 7 is fixed to the support plates 9 from below by screws. .

[0003]

[Problems to be solved by the device] However, maintenance,
When removing the bell mouth for inspection or repair, it is necessary to work with two people because the bell mouth will fall at the moment when the last screw is removed. Since it is easy to lose the rabbit head screw because it is held down and the screw is removed with the other hand, it takes extra time to search, and there is a drawback that the work time becomes long and the construction cost becomes high.

[0004]

In order to solve the above problems, according to the present invention, a fan and a heat exchanger surrounding the fan are provided in a box-shaped main body having an open lower part. An air conditioner that is in contact with the lower surface and covers the open surface with a shielding member, which has an inlet port facing the fan and an outlet port between the main body and the inlet port, and the inlet port is covered with a bell mouth. In the above, a support body for holding the shielding member from below is provided, the bell mouth is fixed to the support body, and a holding portion for holding the bell mouth peripheral portion is provided on the support body.

[0005]

Operation: Even if all the screws are removed, one end of the bell mouth is clamped by the support plate and does not fall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioner according to the present invention will be described below with reference to FIGS. 1 is a cross-sectional view of the present air conditioner, FIG. 2 is a bottom view thereof, and FIG. 1 shows a cross section taken along the line AA of FIG. As shown in the figure, a fan 2 is hung in the center of the inside of a box-shaped main body 1 whose lower side is open, and a heat exchanger 3 is hung so as to surround the fan 2. Same heat exchanger 3
A shielding member 4 which is in contact with the lower surface of the device and also serves as a dew tray has a suction port 5 formed facing the fan 2 and a discharge port 6 is provided between the main body 1 and the cover to cover the open surface. The suction port 5 is covered with a bell mouth 7. Referring to FIG. 3 which is an enlarged bottom view of an essential part and FIG. 4 which is a BB arrow view thereof,
The shield member 4 has four support plates 9 fixed to the main body 1 with two screws at one end and fixed to the main body 1 at the other end with nuts fixed to the screws provided at the lower end of the hanging support rod 8. Is pressed against the heat exchanger 3 from below. One of the support plates 9 is provided with a holding portion that holds the peripheral portion of the bell mouth 7. That is, as shown in FIG. 3, the tip is divided into two parts, a flat plate 9a and a bent plate 9b. A screw hole for fixing a screw for fixing the bell mouth 7 is formed in the flat plate 9a, and the bent plate 9b is temporarily cut. It is bent downward so as to be parallel to the flat plate 9a again with an interval larger than the plate thickness of the bell mouth 7.

Therefore, when removing the bell mouth 7, the three screws of the support plate 9 not shown in FIG. 3 are removed, and finally the screws of the support plate 9 having the form shown in FIG. 3 are removed. As shown by the chain double-dashed line in FIG. 4, the peripheral portion of the mouse is supported by the inner portion of the lower surface of the flat plate 9a and the tip of the bent plate 9b, and is held inclined without falling off. Now remove the screw and remove the bell mouth. On the contrary, when the bell mouth 7 is attached, the proper position of the peripheral portion of the bell mouth 7 is inserted into the holding portion formed by the flat plate 9a and the bent plate 9b, and it is held at an inclination, so that it is screwed and then the remaining three are fixed .

In the above embodiment, the sandwiching portion is composed of a flat plate and a bending plate, but if the bending plates are provided on both sides of the flat plate, the bell mouth can be held more reliably. Further, although a plurality of strip-shaped support plates are used as the support plate, a sandwiching portion may be provided inside the support plate as an annular shape. Although the portion for holding the bell mouth is a recess, it can be omitted depending on the design.

[0009]

[Effects of the Invention] Since the support plate is provided with a holding portion for holding the bell mouth, the bell mouth does not drop even if the last screw is removed when removing it, and therefore the work can be done easily by one person, so the construction cost It is possible to achieve the effect of reducing At the same time, since it is not necessary to hold it with one hand when mounting it, there is an effect that the mounting time can be shortened.
