Air conditioning devices such as air purifiers and air conditioners are widely used to ensure that. As one such air conditioner, a so-called ceiling-embedded type is known, in which the main body of the air conditioner is buried in the ceiling in order to secure indoor space.

[0003] As shown in FIG. 7, this ceiling-embedded air conditioner is installed in the ceiling with the air conditioner main body 21 exposed from an opening (not shown) in the ceiling surface. The decorative panel 23 having an opening 22 is fixed to the main body 21 to close the gap between the ceiling plate (not shown) and the lower surface of the main body 21. , a grill 2 is installed in the opening 22 of the decorative panel 23.
5 are arranged so as to be openable and closable. The decorative panel 23 has decorative panel mounting plates 24 attached to the four corners of the opening 22 and is attached to the main body 21 with mounting screws 27.

[0004] The decorative panel mounting plate 24 has a rectangular shape, and as shown in FIGS. A slit 24b having an insertion hole 24a and extending in one direction from the insertion hole 24a is narrower than the outer diameter of the head 27a of the mounting screw 27 and wider than the outer diameter of the shaft 27b of the mounting screw 27.
and a mounting hole 24c for attaching to the decorative panel 23 is provided in the longitudinal direction of the long side (hereinafter referred to as
(referred to as a slit type), or as shown in FIG.
There is a decorative panel mounting plate 34 (hereinafter referred to as a non-slit type) which has a mounting hole 34b and a mounting hole 34b provided in the longitudinal direction of the long side.

[0005] The above-mentioned slit type decorative panel mounting plate 2

[0007]

[Problems to be Solved by the Invention] By the way, the use of the slit type decorative panel mounting plate 24 has the advantage that one person can install the decorative panel 23 because it can be temporarily fixed. 24b
In order to attach it to the decorative panel 23 so that it is in the same direction with respect to the insertion hole 24a, (A) and (
B) As shown in the insertion hole 24a and the slit 2
There are two types of decorative panel installations, one with a mounting hole 24c on the lower side (see Figure 8 (A)) and one with a mounting hole 24c on the upper side (see Figure 8 (B)) with the 4b in between. A plate 24 is required. Therefore, when attaching the decorative panel 23 to the decorative panel 23, the two types of decorative panel mounting plates 24 must be attached with the directions of the slits 24b relative to the insertion holes 24a aligned in one direction, which is very complicated and troublesome. Also,
Due to this complexity, the decorative panel mounting plate 24 may be installed upside down or left and right. In this case, the direction of each slit 24b with respect to the insertion hole 24a is different,
There is a problem that not only can the decorative panel 23 not be temporarily fixed to the main body 21, but also that the decorative panel 23 cannot be attached to the main body 21. Furthermore, since two types of decorative panel mounting plates 24 are required, there is a problem in that the manufacturing cost increases. Furthermore, the insertion hole 2 of the slit 24b
Since the direction relative to 4a is only one direction, there is also the problem that if the mounting position is shifted, a gap will be created between the ceiling and the decorative panel 23.

On the other hand, if a non-slit type decorative panel mounting plate 34 is used, since it does not have slits,
There is no problem even if the decorative panel mounting plate 34 is mounted upside down or left and right, but on the other hand, temporary fixing cannot be performed. therefore,
One person is required to support the decorative panel 23 and another person is required to attach the mounting screws 27, and the decorative panel 23 cannot be attached to the main body 21 by one person, resulting in a problem that it requires a lot of labor.

The present invention provides a ceiling-embedded air conditioner that is easy to attach to a decorative panel, has low manufacturing costs, and allows the decorative panel to be attached to the main body of the device without creating a gap between the ceiling and the ceiling. The purpose is to provide a decorative panel mounting plate for.
