Abstract

PROBLEM TO BE SOLVED: To provide an air conditioner of a type which is embedded in a ceiling, wherein a space in the ceiling necessary for an installation of the air conditioner can be minimized so as not to be an obstacle to various ceiling equipments while facilitating an installation of the air conditioner. SOLUTION: In a space defined along a slanted side plate 9 of a box body and above one of four corners of an ornamental panel 8, an electrical equipment box 11 which accommodates a control device including a connecting terminal base 10 is disposed. Due to such a construction, an opening formed in a ceiling can be minimized and the ornamental panel 8 can also be made compact so that a space in the ceiling necessary for installing an air conditioner can be minimized so as not to be an obstacle for various ceiling equipments. Furthermore, since the center of the opening in the ceiling and the center of the box body are agreed with each other, it is unnecessary to determine two central positions so that an installation of the air conditioner is facilitated.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical equipment box mounting structure for a ceiling-embedded air conditioner.

[0002]

2. Description of the Related Art Conventionally, an air conditioner is disclosed in Japanese Patent Laid-Open No. 4-1316.
The one described in Japanese Patent No. 28 is known.

9 and 10 show the structure of a conventional air conditioner, and FIG. 9 is a plan view of the conventional air conditioner.
FIG. 10 is a vertical sectional view of a conventional air conditioner.

As shown in the figure, the conventional air conditioner has a heat exchanger 21, a blower 22, and a blower electric motor 23.
And the drain pan 24 that receives the condensed water from the heat exchanger 21
And a decorative panel 28 having an air outlet 26 and an air inlet 27. Has been done. Then, by rotating the blower 22 by the blower electric motor 23, the air in the air-conditioned room is sucked through the suction port 27 of the decorative panel 28, passed through the heat exchanger 21, and the air after the heat exchange is blown out from the air outlet 26. The air is conditioned by blowing the air into the air-conditioned room. Then, when the decorative panel 28 is removed, the electrical equipment box 25 is slidably moved and can be taken out.

In this air conditioner, the space occupied by the air conditioner in the ceiling at present is made small so as not to interfere with various equipment installed on the ceiling, and the installation work cost is reduced. Therefore, easy installation work and easy maintenance are required.

An object of the present invention is to reduce the installation space of the ceiling in such an air conditioner, to facilitate the installation work and the maintenance.

[0007]

In order to achieve this object, the present invention provides an electrical equipment box in which a control device including a connection terminal block is housed in a space formed at the upper part of four corners of a decorative panel by a side plate of a box body. Is configured.

As a result, the opening of the ceiling must be made larger than the box by the size of the electrical equipment box, and the opening must be covered with a decorative panel, thus increasing the space occupied by the air conditioner on the ceiling. By attaching the electrical equipment box to the slant side plate portion in which the corner portion is cut off diagonally, the ceiling opening portion can be made small and the decorative panel can be made small, and thus the space occupied by the air conditioner in the ceiling can be reduced. Also, since the center of the ceiling opening and the center of the box coincide, it is not necessary to provide two types of center points for the ceiling opening and the box installation during installation work, and there are few mistakes in installation work Becomes

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention has a cross section of a substantially quadrangular shape, a heat exchanger, a blower, and a drain pan are housed therein, and a corner portion extending in the vertical direction is obliquely cut.
