Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a ceiling panel for an in-ceiling type air conditioner, and particularly to an in-ceiling type air conditioner in which the ceiling panel is separated into an outer panel and an inner panel. This concerns the ceiling panel of the aircraft.

[Technical background of the invention and its problems]

Generally, the structure of the ceiling panel of a ceiling-embedded air conditioner is known as shown in FIG.

As shown in the figure, a ceiling panel a having an overall rectangular shape is provided with a suction port c having a suction grille b having the same shape as the panel a. This suction grill b and a support plate d that surrounds and supports it.
The inner panel e is formed by. Furthermore,
An outer panel f that surrounds and supports the inner panel e is provided on the outer periphery of the inner panel e, and an air outlet g is provided around the entire circumference except for the four corners in order to support the inner panel e. ing.

As a result of the above, the ceiling panel a becomes the inner panel e.
It is molded into an integral structure of the air conditioner and the outer panel f, and is attached to the ceiling plate side, which is the lower part of the air conditioner embedded in the ceiling.

By the way, when the ceiling panel a is molded into an integral structure, the following problem occurs.

(1) When installing an air conditioner, the ceiling panel a is heavy, so if one person is doing the installation work, it is not easy to do the installation work, and furthermore, it is dangerous because the work must be done at a high place.

(2) During maintenance, it is necessary to remove ceiling panel a, which has an integral structure, and perform the work.
Furthermore, after the work is completed, it is necessary to adjust the alignment of the ceiling panel a and the ceiling board, which results in poor workability during maintenance.

(3) When creating an integral structure, connecting parts are required to connect them, and when integrally molded using foamed material, etc., the mold and equipment costs for making it increase, and in either case, costs increase.

(4) In the case of the four-way type ceiling panel a, there are connection parts between the inner panel e and the outer panel f at the four corners, so no air blows out from these parts.

[Purpose of invention]

The present invention was created in consideration of the above circumstances, and has excellent workability during installation and maintenance of ceiling-embedded air conditioners, is low cost, and blows air effectively from the air outlet to all four directions. The purpose of the present invention is to provide a ceiling panel for a ceiling-embedded air conditioner.

[Summary of the idea]

In order to achieve the above object, the present invention embeds the main body of an air conditioner in the ceiling, and the ceiling has a suction port inside and an air outlet along the outer periphery of the suction port at the bottom of the main body of the air conditioner. In a ceiling-embedded air conditioner equipped with a panel, an air outlet is formed by continuously cutting the ceiling panel into an annular shape along the outer periphery of the air inlet, and an inner panel having the air inlet and the air outlet are formed. It is constructed separately from an outer panel that partitions the outer side of the inner panel, and the inner panel and outer panel can be attached and detached independently to improve workability during installation and maintenance.

[Example of idea]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the air conditioner main body 1 is attached via a hanging fitting 3 to a hanging bolt 2 hanging from the ceiling. The ceiling panel 4 of the present invention is attached to the lower side of the air conditioner main body 1, and is adjusted so that the panel 4 is flush with the ceiling plate surface. In addition, 5 is a blower, 6
is a heat exchanger, and 7 is a drain plate.

The ceiling panel 4 is provided with an inlet 8 in a portion located directly below the blower 5, and an annular outlet 9 on the outer periphery of the inlet 8. This results in
The ceiling panel 4 is connected to the inner panel 1 with the air outlet 9 as a boundary.
0 and an outer panel 11. The outer panel 11 is the outer frame 1 of the air conditioner main body 1.
2 via an outer panel attachment part 13. The inner panel 10 is attached to a support plate (not shown) that supports the heat exchanger 6 and the drain tray 7 via an inner panel attachment part 14. Furthermore, a suction port grill 15 is detachably attached to the suction port 8 of the inner panel 10 so that it can be easily removed by hand. Note that 16 is an air filter.

In the air conditioner configured as described above, indoor air is sucked in from the suction port 8, passed through the heat exchanger 6, and then distributed throughout the room from the air outlet 9 provided around the entire outer circumference of the suction port 8. Effectively blow out.

When installing the air conditioner on the indoor ceiling, the air conditioner main body 1 is attached to the hanging bolts 2 via the hanging fittings 3, and the outer panel 11 is fixed to the outer frame 12 of the main body 1 and aligned with the ceiling plate surface. Then, the inner panel 10 is attached. Next, the suction grill 15 is attached.

When carrying out maintenance work, the suction grill 15 is removed, bolts (not shown) etc. of the inner panel mounting portion 14 are removed, and the inner panel 10 is removed. In this way, most maintenance work can be performed simply by removing the inner panel 10.

[Effect of idea]

In summary, the present invention exhibits the following excellent effects.

(1) Since the ceiling panel of the air conditioner is separated into an inner panel and an outer panel, the weight of each panel is reduced during installation work, improving work efficiency.

(2) During maintenance, most work can be done simply by removing the inner panel, and there is no need to remove the outer panel, so there is no need to adjust the ceiling plate surface and the ceiling panel.

(3) Since there is no need to connect the inner panel and the outer panel, there is no need for a connecting member, and the manufacturing cost of the ceiling panel can be reduced.

(4) Since the air outlet is provided around the entire circumference of the inlet, the air after heat exchange is effectively blown out throughout the room.
