Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling panel of a novel ceiling-embedded air conditioner, and more particularly to covering a peripheral edge of an opening formed in an indoor ceiling wall and the back surface of the opening and the indoor ceiling wall. The present invention relates to a ceiling panel in which a duct for connecting the air conditioner main body installed in a room and sucking indoor air and blowing out indoor air after heat exchange is improved, and the duct portion is formed to be expandable and contractible. ..

[0002]

2. Description of the Related Art Generally, an opening is formed in an indoor ceiling wall,
The air conditioner main body is installed from this opening to the back surface of the ceiling wall, and the above-mentioned opening is used as an indoor air intake to the air conditioner main body and a ceiling embedded type formed as an outlet for blowing out indoor air after heat exchange. Air conditioners are known.

Conventionally, a generally known ceiling-embedded air conditioner has the structure shown in FIG. As shown in the figure, an opening b is formed in the indoor ceiling wall a, and the air conditioner body c is installed from this opening b to the back surface of the ceiling wall a. Further, the air conditioner main body c inserted from the opening b to the back surface portion or the inner side surface portion of the ceiling wall a has a beam frame d located above the ceiling wall a via a suspension rod e and an opening portion of the ceiling wall a. It will be installed at a predetermined height from b. Air conditioner body c installed in this way
A ceiling panel j is attached to the. This ceiling panel j
Is a duct h that connects the opening b and the air conditioner main body c to form a suction passage f for sucking indoor air and a blowing passage g for blowing out the indoor air after heat exchange.
And a cover panel i that covers the peripheral edge of the opening b are integrally formed. The ceiling panel j is inserted into the opening b of the ceiling wall from the duct h and is connected and attached to the air conditioner main body c which is installed in advance.

[0004]

In the conventional ceiling panel of this type, as shown in FIG. 5, the opening b of the ceiling wall a is conventionally used.
Since the cover panel i that covers the peripheral edge of the duct and the duct h are integrally formed and the length of the duct h is constant, the following problems occur.

In many cases, a distance or a gap between the ceiling wall a on which the air conditioner main body is installed and the beam frame d and the like above the ceiling wall a is different depending on a building structure such as a building, a store, or a hotel. Even in the same building structure, the height of the back surface of the ceiling wall may differ depending on each floor. Therefore, if the length of the duct h of the ceiling panel j is constant, it may not be possible to connect it to the air conditioner main body c even if it is inserted from the opening b. As described above, when the length of the duct h is short, the air conditioner main body c which is first suspended and installed on the beam frame d by the suspension rod e or the like.
Can be solved by attaching the ceiling panel j after pulling it down so as to approach the opening b and supporting it. However, since the air conditioner main body c installed in advance has a considerable load, there is a problem that the work for adjusting the position is complicated.

Ii In addition, when the gap or distance on the back surface of the ceiling wall a is relatively small or extremely large,
A method of forming the ceiling panel j by making the length of the duct h correspond to these distances or gaps is adopted. By the way, if such a method is adopted, it is necessary to manufacture ceiling panels having different duct lengths for a large number of models, which increases the development burden and tends to be unable to meet the market demand. Further, when the number of models increases as described above, not only mass production cannot be performed, but also the cost becomes high and the delivery time is delayed.

Furthermore, when installing the ceiling panel,
Since it is necessary to select a model suitable for the height of the ceiling, there is a problem that the workability is complicated because it takes time and labor such as the order of carrying out from the warehouse and the method of carrying in the building to be installed.

Therefore, an object of the present invention is to solve the above-mentioned problems, and in a ceiling-embedded air conditioner in which the air conditioner main body is installed on the back surface of the indoor ceiling, the height of the ceiling back surface on which the air conditioner main body is installed is high. To provide a ceiling panel of a ceiling-embedded air conditioner in which a ceiling panel that also serves as a duct can be easily attached to the previously installed air conditioner main body even if the gaps are different. is there.

[0009]

In order to achieve the above object, the present invention is inserted into the air conditioner main body installed on the back surface of the ceiling wall through the opening formed in the ceiling wall of the room. , The insertion front end is connected and the insertion rear end reaches the opening to form a duct for sucking indoor air and blowing out indoor air after heat exchange, and the insertion rear end is a peripheral portion of the opening. In a ceiling panel of a ceiling-embedded air conditioner that forms a cover panel for covering, the duct is divided into a main body side duct connected to the air conditioner main body side and an opening side duct having the cover panel, The divided end portions are overlapped with each other by a predetermined length in the longitudinal direction of the duct to form the opening side duct so that it can expand and contract from the main body side duct, and the main body side duct and the opening side duct are fixed to each other. Configured coupling means that are provided.

[0010]

According to the above construction, the duct portion of the ceiling panel is formed so as to be expandable and contractible by pulling the opening duct out of the main body side duct or pulling it back in the longitudinal direction, and is formed on the indoor ceiling wall first. The ceiling panel can be attached to the opening and the air conditioner main body while adjusting the length of the duct portion of the air conditioner main body installed on the rear surface of the opening ceiling wall. Therefore, even if the height of the ceiling back surface is different and the distance between the opening of the ceiling wall and the air conditioner body is not constant, the length of the duct portion can be arbitrarily adjusted to attach the ceiling panel.
