As shown, the present invention in the air conditioner provided with an inlet opening and closing device 140 for opening and closing the front panel 130 of the inlet 120 for sucking air into the indoor unit 100, the inlet opening and closing device ( 140, the drive means 142 is installed on the case 110 side; First and second fixing rollers 144a and 144b fixedly disposed at the suction port 120 side; A rotating plate 146 guided and moved by the first fixing roller 144a; A rack gear 148 which is guided by the second fixed roller 144b and moves forward and backward; A first pinion gear 141a which rotates by receiving power from the driving means 142; A second pinion gear 141b which meshes with a first pinion gear 141a and the rack gear 148 and rotates; And first and second guide grooves 143a and 143b for guiding the movement when the pivoting plate 146 moves and for controlling the movement distance. Characterized in that it comprises a.

First, the indoor unit 100 of the air conditioner is fixed and supported various components for heat exchange therein.

Then, the driving means 142 of the inlet opening and closing device 140 for opening and closing the inlet 120 of the indoor unit 100 is disposed close to the rotation center of the front panel 130 is installed on the case 110 side.

The first and second fixing rollers 144a and 144b guide the rotating plate 146 and the rack gear 148 and are fixedly disposed at the case 110 on the suction port 120 side.

In addition, the rotating plate 146 is moved by a predetermined width while being guided by the first fixing roller 144a.

On one side of the rotating plate 146 guided by the first fixed roller 144a, the rack gear 148 having the teeth 148a guided by the second fixed roller 144b and moving forward and backward is formed. It is provided. The rack gear 148 may be integrally formed with the rotating plate 146 to be injection molded.

In addition, the first pinion gear 141a constituting the inlet opening and closing device 140 of the indoor unit 100 for the air conditioner rotates by receiving the power of the driving means 142 when the air conditioner operates.

In this process, the front panel 130 that opens and closes the inlet 120 of the indoor unit 100 is opened. When the front panel 130 is opened, the first pinion gear 141a achieves a reverse rotation state. do.

In addition, when the operation of the air conditioner is terminated and the front panel 130 is closed, the first pinion gear 141a achieves a forward rotation state.

In addition, the second pinion gear 141b rotates in the reverse process in the process of opening the front panel 130 of the indoor unit 100, and when the front panel 130 is closed, the first pinion gear 141a and the forward rotation state. It rotates in engagement with the teeth 148a of the rack gear 148 which moves forward and backward.

In addition, when the front panel 130 of the indoor unit 100 is closed, the second pinion gear 141b meshes with the teeth 148a of the first pinion gear 141a and the rack gear 148 which form a forward rotation state. Rotate in reverse rotation.

The locking pins 145a and 145b inserted into the first and second guide grooves 143a and 143b to be described later are provided at the centers of the first and second pinion gears 141a and 141b. The first and second pinion gears 141a and 141b are preferably provided in the case 110 on the suction port 120 side.

In addition, the first and second guide grooves 143a and 143b guide the movement of the first and second pinion gears 141a and 141b when the rotating plate 146 moves and control the moving distance.

That is, the locking pins 145a and 145b formed to protrude from the center of the first and second pinion gears 141a and 141b are inserted into the first and second guide grooves 143a and 143b, thereby driving power by the driving means 142. When the front panel 130 of the indoor unit 100 is received and opened, the pivoting plate 146 serves as a guide in the process of moving forward and backward.

In addition, the locking pins 145a and 145b are caught in the first and second guide grooves 143a and 143b to control the movement thereof.

Hereinafter, the operation of the inlet opening and closing device of the air conditioner according to the present invention.

First, when the air conditioner is operated by a user's operation, the first pinion gear 141a is reversely rotated by the operation of the driving means 142 which transmits power to the inlet opening and closing device 140, and at the same time, the second pinion gear ( 141b is engaged with the teeth 148a of the first pinion gear 141a and the rack gear 148 and rotates forward to open the front panel 130. As a result, the suction port 120 is opened and the indoor air is introduced into the indoor unit 100 while the blower 150 for sucking hot air in the room is operated toward the heat exchanger 160.

In this way, the air introduced into the indoor unit 100 is in a low temperature state in contact with the heat exchanger 130 due to the characteristics of the low pressure and the temperature of the refrigerant flowing through the interior of the indoor unit 100, the air in this low temperature state It is supplied back to the indoor space through the discharge port 122.

When the operation of the air conditioner is terminated, the blower 150 is stopped and the front panel 130 is closed by the reverse operation of the inlet opening / closing device 140 which opens the inlet opening 120 so that the inlet opening 120 is closed. will be.
