JPH0960965A - Hanging device of air conditioner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a work saving air conditioner which is capable of adjusting elevations in a short time without removing a decorated panel, if a clearance is produced between the decorated panel and a ceiling surface during the installation of an air conditioner. SOLUTION: A cylinder into which a hanger bolt is inserted, is provided on a hanger metal fitting fixed with the hanger bolt which hangs indoor equipment from a building. A stopper mechanism is mounted inside the cylinder where the stopper mechanism comprises a claw 5 which encroaches upon the hanger bolt, a spring 6 which pushes the claw in and a frame 7 which houses the claw 5 and the spring 6. The hanger bolt is designed to run through unidirectionally alone but not allowed to run through reversely.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension device for an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art As a conventional air conditioner suspension fitting, four mounting plates with round holes or U-shaped holes are attached to the outer periphery of the air conditioner,
The structure was such that a hanging bolt was passed through the hole and the top and bottom of the attachment plate were fixed with nuts. In this structure, once fixed, it was necessary to loosen the nut once in order to adjust the position of the suspension fitting. There is also an improvement as shown in JP-A-4-148127, but in a ceiling-embedded cassette type air conditioner in which a decorative panel is attached to the lower surface of the indoor unit main body, it was necessary to remove the decorative panel once to adjust the position. .

SUMMARY OF THE INVENTION An object of the present invention is to adjust the hanging height of an indoor unit in a ceiling-embedded cassette type air conditioner in which a decorative panel is attached to the lower surface of the indoor unit body without removing the decorative panel. It is to provide a hanging structure capable of

[0004]

[Means for Solving the Problems] By providing a cylinder through which a hanging bolt penetrates in a hanging metal fitting of an indoor unit, and by providing a stopper mechanism inside of which a hanging bolt passes only in one direction and does not pass in the opposite direction. , After suspending the indoor unit once,
It can be pushed up only, and when a gap is created between the ceiling surface and the decorative panel, the gap can be eliminated by pushing up the decorative panel and the indoor unit together.

[0005]

The stopper mechanism provided inside the cylinder through which the suspension bolt penetrates allows the suspension bolt to pass only in one direction and not in the opposite direction. The indoor unit can be hung by using this non-passing direction as the hanging direction.
In addition, the indoor unit can be lifted upward by utilizing the passing direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. Figure 1 shows how to install a ceiling-embedded cassette type air conditioner. The main body 1 has an octagonal shape, and the suspension device 4 is attached to four corners of the corner. Hanging device 4
A suspension bolt 3 suspended from the structure of the building
By fixing each of them, the main body 1 is held in a suspended form above the ceiling of the building. Next, the ceiling surface 9
The decorative panel 2 is attached in order to hide the opening that is opened in the. The decorative panel 2 is fixed to the decorative panel suspension device 13 attached to the lower surface of the main body with screws from the lower surface of the decorative panel 2. By the screwing operation, the lower surface of the main body 1 and the upper surface of the decorative panel 2 can be brought into close contact with each other to form a suction passage and a blow-out passage for conditioned air. In the unlikely event that this adhesion is insufficient, air leakage will occur in the conditioned air intake passage and blowout passage, causing problems such as dew condensation, so that the lower surface of the main body 1 and the upper surface of the decorative panel 2 will be damaged. Adhesion must be sufficient. FIG. 2 shows the suspension device 4 attached to the corner of the main body 1. The suspension device 4 includes a cylinder 8 through which the suspension bolt 3 is inserted, claws 5 which bite into the suspension bolt 3,
It is composed of a spring 6 that pushes the claw 5 and a frame 7 that houses the claw 5 and the spring 6. From the top of the figure, the hanging bolt 3
When it is inserted into, it hits the claw provided at the outlet of the cylinder. Further, when the suspension bolt 3 is pushed in, the spring 6 which presses the claw 5 contracts, the claw 5 opens to the left and right, and the suspension bolt 3 penetrates the tube 8 and becomes the shape shown in FIG. At this time, hanging bolt 3
Even if an attempt is made to pull it up in the figure, the claw 5 pushed into the spring 6 is caught in the hanging bolt 3 and cannot be pushed upward, but can be pushed downward. The hoisting work when this device is used will be described with reference to FIGS. FIG. 4 shows a state in which the main body 1 is suspended by the suspension bolts 3 and the decorative panel 2 is attached to the lower surface of the main body. When the decorative panel 2 is in close contact with the lower surface of the main body 1 and a gap S is generated between the decorative panel 2 and the ceiling surface 9, in order to eliminate this gap S, the hanging position 4 of the main body is moved upward to the gap S in the figure. It is necessary to raise it by the amount. At this time, in the case of the conventional main body suspending device in which the suspension bolt 3 as shown in FIG. 6 is fixed to the suspension fitting 12 with the two nuts 10, the decorative panel 2 is once removed from the main body 1 and the ceiling opening portion is removed. Since the nut is further rotated and shifted upward to adjust the hanging height of the main body 1, the decorative panel 2 is attached to the main body 1 again, which is very troublesome. In the suspending device of the present invention, in the state of FIG. 4, the decorative panel 2 and the main body 1 are pushed upward together from the lower surface of the decorative panel 2, so that the position of the suspending device 4 is displaced above the hanging bolt 3 and the main body is moved. It is possible to shift the hanging height of 1 upward. As shown in FIG. 5, after the decorative panel 2 is pushed upward until it hits the ceiling surface 9, the pawl 5 of the hanging device 4 bites into the hanging bolt 3 even if the pushing force is lost.
The main body does not descend downward, and the gap S can be eliminated. According to the present embodiment, when the air conditioner is installed, if a gap S is generated between the decorative panel and the ceiling surface, a work-saving air conditioner that can adjust the height in a short time without removing the decorative panel is provided. You can

[0007]

According to the present invention, when the air conditioner is installed, if a gap S is generated between the decorative panel and the ceiling surface, the height can be adjusted in a short time without removing the decorative panel, and the construction-saving air conditioning is possible. Machine can be provided. As a result, the number of units that can be installed at the same time can be increased, which is economically superior.
