Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner of a ceiling embedded type or a ceiling suspended type.

[0002]

2. Description of the Related Art FIG. 2 is a longitudinal sectional view showing the structure of a conventional ceiling type air conditioner of this type, and FIG.
FIG. FIG. 4 is a perspective view of a main part of the air conditioner.

A heat exchanger 7, a drain pan 10, a blower 6, a fan motor 5, a baffle plate 12 and the like are arranged inside a unit body 2 buried in a ceiling 1, and the unit body 2 has a lower part. A ceiling panel 8 covering the opening is detachably mounted. A suction port 3 is formed in the center of the ceiling panel 8, and blowout ports 4 are formed on both sides of the suction port 3.

[0004] A suction grill 11 is fitted into the suction port 3, and a filter 13 is detachably locked behind the suction grill 11. Four motors 20 capable of normal and reverse rotation (forward rotation and reverse rotation) are fixed to brackets 15 and 16 attached to the inner wall of the ceiling panel 8, and each sprawl 21 driven by each of these motors 20 has , The base end of each wire 22 is wound.

The ends of these wires 22 are connected to the four corners of the suction grill 11 via rings 24 attached to brackets 15 and 16, respectively. Each of the sprawls 21 is fixed to the corresponding output shaft 20 a of the motor 20.

When cleaning the filter 13 in such a configuration, the motor 20 is rotated in the reverse direction. As a result, the four wires 22 are rewound from the four sprolls 21, and when the suction grill 11 is lowered to a predetermined height while keeping the horizontal state, the motor 20 is stopped. In this state, the worker on the floor removes the filter 13 from the suction grill 11 and cleans it.

When the cleaning is completed, the operator enters the filter 13
Is attached to the suction grill 11 again, and the motor 20 is rotated forward, whereby the sproll 21 winds up the wire 22. When the suction grill 11 rises and comes into contact with the lower surface of the ceiling panel 8, the motor 20 is stopped.

[0008]

The air conditioner having the above-mentioned structure requires a motor, a sprawl, and four wires, respectively, and thus has a problem that it is expensive in manufacturing. An object of the present invention is to provide an air conditioner that can be manufactured at a low cost with a simple configuration.

[0009]

Means for Solving the Problems To solve the above problems and achieve the object, an air conditioner of the present invention is configured as follows. (1) The air conditioner of the present invention is an air conditioner that is installed on a ceiling and configured such that a suction grill or a filter alone having a built-in panel or filter facing the indoor side can move up and down with respect to the unit body. One end of a sheet is fixed to at least two opposite sides of the panel, the suction grille, or the filter alone, and the other end of each sheet is installed in another part of the unit body side, and the rotation of the motor capable of rotating forward and reverse is performed. The panel, the suction grille, or the filter alone can be moved up and down with respect to the unit body by being fixed to each roller connected to a shaft, and winding and rewinding each sheet with forward and reverse rotation of each roller. (2) The air conditioner according to the present invention is the air conditioner according to the above (1), wherein the respective sheets are installed in parallel with each other, and the respective rollers for winding and rewinding the respective sheets are parallel to each other. It is installed in.

[0010] As a result of taking the above measures, the following operations occur. (1) According to the air conditioner of the present invention, one end of each of the sheets is fixed to at least two opposite sides of the panel, the suction grille, or the filter alone, and the other end of each of the sheets is fixed to another part on the unit body side. The panel or the suction grille or the filter alone is fixed to each roller connected to a rotating shaft of a motor that is installed and capable of rotating forward and reverse, and the panel or the suction grille or the filter alone is united by rewinding and rewinding each sheet according to forward and reverse rotation of each roller. Since the air conditioner can be moved up and down with respect to the main body, the air conditioner can be manufactured at a low cost with a simple configuration, and the panel, the suction grille, or the filter alone can be moved up and down to clean these parts. .

Further, by using the sheet as a member for winding and rewinding, the panel or the suction grille or the filter unit can be used as compared with a structure in which wires are connected to four corners to move up and down. It is possible to raise and lower in a stable state with less inclination and shaking. (2) According to the air conditioner of the present invention, since the respective sheets are installed in parallel with each other and the respective rollers are installed in parallel with each other, the panel or the suction grille or the filter unit is kept in a horizontal state. It can be raised and lowered while keeping it.

[0012]
