Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner installed mainly on a ceiling of a bathroom or the like to ventilate a room.

[0002]

2. Description of the Related Art Conventionally, as this type of air conditioner, there is known an air conditioner which is mainly installed on a ceiling of a bathroom and which has an attachment frame for attaching an air conditioner main body and a duct connector. Figure 8
FIG. 6 is a cross-sectional view showing an example in which an air conditioner according to a conventional embodiment is installed on a ceiling. As shown in FIG. 8, the conventional air conditioner A has a structure in which the mounting frame 3 is mounted on the ceiling 7, and the duct connector 2 and the main body 1 of the air conditioning device A are mounted on the mounting frame 3. In the case of such a configuration, the reinforcing member 9 for supporting the load of the main body 1 itself of the air conditioner A is attached to the back surface of the ceiling 7.

[0003]

However, in the above-mentioned conventional structure, a member for reinforcing the ceiling 7 is required separately from the mounting frame 3, resulting in high cost. In addition, it is necessary to mount the mounting frame 3 after mounting the reinforcing member 9 on the ceiling, which is troublesome at the time of implementation. The present invention has been made to solve the above problems, and an object of the present invention is to mount the main body of the air conditioner on the ceiling only with the mounting frame without using the conventional reinforcing member 9. An object of the present invention is to provide an air conditioner configured to reinforce the ceiling surface.

[0004]

The present invention relates to an air conditioner having a main body of an air conditioner, a duct connector, and a mounting frame for connecting the duct connector, and the mounting frame is opened in a ceiling or the like. It is characterized in that it is also configured as a reinforcing member arranged on the back surface of the mounting portion for mounting the air conditioner. According to this structure, it is not necessary to separately provide a reinforcing member for the air conditioner mounting portion, so that the structure can be made inexpensive and labor for construction can be saved.

Further, since the mounting frame is mounted and fixed to the mounting surface, the duct connector and the air conditioner body can be easily installed.

Further, since the duct connector can be attached to the attachment frame by one-touch attachment without using tools or screws, it is easy to implement and the implementation time is shortened. Further, since the duct connector can be attached to the attachment frame by screws, the attachment frame and the duct connector can be reliably connected with an inexpensive structure. Further, since the duct connector has a long hole at the joint with the mounting frame, it is possible to connect the duct connector to a predetermined position even if the thickness of the ceiling changes. Further, in the duct connector, since the screw mounting portion has the concave shape, it is possible to prevent the screw heads from interfering with each other when the air conditioner main body is mounted on the mounting frame. Further, since the attachment frame has the elongated hole at the joint with the duct connector, the duct connector can be connected to a predetermined position even if the thickness of the ceiling changes.

Further, the mounting frame is composed of a frame body and a flange portion, and the protrusion is provided on the lower surface of the flange portion.
When the opening of the air conditioner mounting portion is smaller than the opening of the mounting frame, the mounting frame cannot be used and it is possible to prevent the opening of the air conditioner mounting portion and the duct connector from interfering with each other. In addition, since the projection is provided on the entire circumference of the mounting frame, it can be more reliably carried out. Also, by having a structure in which the protruding portion is partially provided to the mounting frame,
The mounting frame can be made at low cost.

Further, since the upper portion of the frame is inclined inward at the portion of the mounting frame which contacts the duct connector, it is possible to prevent the duct from being inclined by the pulling force applied to the duct pipe at the time of implementation, and the main body Will be sure to be enforced.

Further, since the mounting frame is provided with the temporary fixing metal fitting for temporarily fixing the air conditioner main body, it is possible to reduce the labor at the time of performing the operation and allow the operator to perform the operation. In addition, the temporary fixing metal fittings are plate-shaped, one of which is fixed to the mounting frame and the other of which is bendable, so that it can be hooked in the opening of the flange portion of the air conditioner body,
It becomes possible to easily carry out the process without preparing a temporary fixing member. In addition, the temporary fixing metal fittings are claw-shaped, and the claw-shaped ones can be rotated by being fixed to the screw part for fixing the mounting frame. It is possible to configure a temporary fixing mechanism. Also,
The temporary fixing metal fitting is a leaf spring-shaped metal fitting, and since one of the metal fittings is attached to the air conditioner main body, the temporary fixing mechanism can be configured with a simple structure by hooking and fixing it on the mounting frame. The temporary fixing metal fitting is a nail-shaped temporary fixing metal fitting, which is rotatably fixed to the hanging bolt portion fixed to the upper part of the air conditioner main body installation portion, thereby opening the flange portion of the air conditioner main body. Since it is hooked on the portion, the temporary fixing mechanism can be constructed at low cost.

Further, since the mounting frame is provided with a hanging hole for mounting a fixing bracket for fixing from a place other than the mounting surface on which the air conditioner is mounted, even if the mounting surface such as the ceiling has no strength. , It is possible to fix it from the slab surface on the upper floor with hanging bolts.

Further, the mounting frame is provided with a screw pilot hole for fixing to the mounting surface on the flange portion, and the pilot hole is located at a vertically symmetrical position, so that the screw pilot hole for fixing the mounting frame is provided. Serves as a guide for marking on the air conditioner main body mounting portion from the indoor side, and a pattern for marking the prepared hole is not required.

Further, since the mounting frame has a shape capable of being rotated by 180 ° with respect to the center of the mounting surface, the mounting frame can be mounted on the mounting surface such as the ceiling without worrying about the direction.
