Abstract

PURPOSE:To permit to fit closely a decorative panel to a ceiling surface easily by a method wherein an equipment is constituted of a main body fixed to the ceiling surface formed with a flange at an opening edge and the decorative panel provided with a hook protion engaging with the flange. CONSTITUTION:When a hook 14 is engaged with the flange 2b, it is engaged overriding a projected portion 14a by easy power due to the elasticity of the hook 14 and a tapered portion 14b. As a result, a blow-off decorative panel 3b is moved upward compulsority, the rim 3a of the decorative panel 3 also is moved upward and an air conditioner is fitted closely to ceiling surface 4. Accordingly, the decorative panel 3 is attached to the ceiling surface, the main body is fixed to a position in which the flange 2a is contracting with the ceiling 4 upon the installation of the main body 1, and the decorative panel 3 is fixed to the main body 1 in a condition that the peripheral rim 3a of the panel 3 is neighbored to the ceiling surface 4, whereby the rim 3a of the decorative panel 3 may be fitted closely to the ceiling surface 4 by only engaging the flange 2b with the hook 14 of the decorative panel 3 without effecting troublesome positioning.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ceiling-embedded air conditioner that is installed embedded in the ceiling.

Conventional Structures and Problems Generally, a ceiling-embedded air conditioner has a decorative panel serving as a grille exposed to the ceiling surface and attached to the main body. Therefore, if the ceiling surface is deformed, a gap may occur between the ceiling surface and the decorative panel, which may deteriorate the appearance of the X- after installation, or cause chattering noise between the decorative panel and the ceiling surface due to the vibration of the main unit. This often happened.

For this reason, the decorative panel is installed closely against the ceiling surface, but in this case, the decorative panel is generally fixed directly to the ceiling surface with screws, or when the decorative panel is fixed to the ceiling-mounted air conditioner body. The ceiling-mounted air conditioner body is pre-fixed to the ceiling at a dimensional position where the decorative panel is in close contact with the ceiling surface. In the former case, it was necessary to make mounting holes on the ceiling to tighten the screws, and the mounting holes on the decorative panel had to match with the mounting holes on the ceiling, which resulted in very poor workability. . In addition, in the latter case, when fixing the ceiling-mounted air conditioner to the ceiling in advance, it is necessary to make fine adjustments in consideration of warpage and distortion of the decorative panel, which makes the work cumbersome and also causes damage to the ceiling surface. It had the disadvantage of causing fatigue due to the work involved.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and
``--- To provide a ceiling-embedded air conditioner that can easily bring a decorative panel into close contact with a ceiling surface.

Structure of the Invention To achieve this object, the ceiling-embedded air conditioner of the present invention includes a main body fixed to a ceiling surface with a flange formed on the edge of the opening, and a decorative body provided with a hook part that engages with the flange. It consists of a panel, and the decorative panel is brought into close contact with the ceiling surface by engaging the flange and the hook part.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a cross section of a ceiling-embedded air conditioner according to an embodiment of the present invention. In Figure 1, 1 is the main body of the ceiling-mounted air conditioner, and the main body casing 2 is approximately U-shaped.
and a decorative panel 3 covering the opening of the casing 2. The main body casing 2 is inserted through an opening 5 made in the ceiling surface 4 of the air-conditioned room and positioned in the ceiling, and the decorative panel 3 is exposed from the ceiling surface 4 and attached to a part of the main body 1 using screws 6 or the like. Fixed. In addition, there is a grill 7 in the center of the decorative panel 3.
A suction port 8 with a Blower 1
゛1. A pair of heat exchangers 12 are respectively arranged. On the other hand, a flange 2a that contacts the ceiling surface 4 is formed at the lower end of the main body casing 2, and the decorative panel 3 forms a peripheral edge 3a to cover this flange 2a. Joint part 1 between the main body casing 2 and the air outlet 9 of the decorative panel 3 in the ventilation passage 1o
3 has a flange 2a on the lower opening edge of the main casing 2.
A suitable number of flanges 2b are formed in the opposite direction, and a hook part 14 is formed at the joint part 13 on the decorative panel 3 side.

This hook portion 14 has elasticity and consists of a protrusion portion 14a that engages with the flange 2b, and a tapered portion 14b that slopes from the protrusion portion 14a to the tip of the hook portion 14. When the hook portion 14 engages with the flange 2b, the elasticity of the hook portion 14 and the tapered portion 14b allow the hook portion 14 to easily overcome the projection portion 14a and engage with the flange 2b. As a result, when the 6″′-puff flange 2b and the hook portion 14 are engaged, the blowout decorative panel portion 3b forming the air outlet 9 of the decorative panel 3 is forcibly moved upward, and the blowout decorative panel portion 3b As the decorative panel 30 moves, the peripheral edge 3a of the decorative panel 30 also moves upward and comes into close contact with the ceiling surface 4.

Therefore, when attaching the decorative panel 3 to the ceiling surface 4, the main body 1 is sometimes fixed at a position where the flange 2a is in contact with the ceiling surface 4, and the peripheral edge 3a of the decorative panel 3 is attached to the ceiling surface 4. The decorative panel 3 is placed close to the main body 1.
If it is fixed to the ceiling surface 4, the peripheral edge 3a of the decorative panel 3 can be brought into close contact with the ceiling surface 4 simply by engaging the flange 2b and the hook part 14 of the decorative panel 3 without any troublesome positioning. Installation work becomes extremely easy.

Effects of the Invention As described above, in the ceiling-embedded air conditioner of the present invention, the hook provided on the decorative panel is engaged with the flange formed at the edge of the main body opening, so that the decorative panel and the ceiling surface are brought into close contact. Therefore, when attaching the decorative panel to the ceiling surface, there is no need to drill a mounting hole in the ceiling surface, and there is no need to set the position, so close-contact construction can be easily performed.

Furthermore, the elasticity of the seven lunges allows the decorative panel to adhere closely to the ceiling surface without requiring correction of irregularities or dimensional errors in the ceiling surface, and has many other advantages.
