The present invention relates to an air conditioner, and more particularly, to a control box coupling device of an air conditioner for smoothly coupling a control box in a hybrid air conditioner.

In general, an air conditioner rotates a cross flow fan to suck hot air in a room, and then heats the sucked hot air by a heat exchanger to change it to cold air, and then replaces the cold air with the rotational force of the cross flow fan. By discharging to the room to cool the room to an appropriate temperature, the air conditioner can be used as a wall-mounted type attached to the wall, a ceiling-mounted type attached to the ceiling, and a stationary type mounted on the floor. Qi.

As shown in FIG. 1, the air conditioner includes a front panel 1 constituting the front of the air conditioner; A rear panel (2) installed at the rear of the front panel (1); A control box 11 coupled to the rear panel 2 by a control box coupling device and installed to control a signal generated from an air conditioner; A cross flow fan (6) installed in the air conditioner and rotated to suck hot air in the room into the air conditioner, and to discharge air to the outside of the air conditioner; A suction grill (4) installed at a lower end of the front panel (1) to suck in hot air of the room; A heat exchanger (5) through which cold refrigerant flows to heat exchange the air sucked through the suction grill (4); A rear guide (7) installed at the upper end of the air conditioner to guide the flow direction of the air so that the air flowing by the rotational force of the cross flow fan (6) is discharged to the outside of the air conditioner; A drain plate 9 installed at the rear of the front panel 1 to receive condensed water generated when the sucked air passes through the heat exchanger 5 and is heat-exchanged; A drain hose (10) installed to be coupled to the drain plate (9) to discharge the condensed water accumulated in the drain plate (9) to the outside of the air conditioner; A stabilizer 8 installed to control a discharge angle of air discharged at an upper end of the drain plate 9; It consists of a louver (3) provided at the upper end of the front panel (1) to adjust the discharge direction of the air discharged to the outside of the air conditioner (1).

In the air conditioner having such a structure, when the user selects the cooling operation mode while power is supplied to the air conditioner, the suction force is generated because the cross flow fan 6 installed in the air conditioner is rotated by receiving the driving force of the motor. Hot air in the room is sucked into the air conditioner through the suction grill 4 installed at the lower end of the front panel 1 of the air conditioner.

At this time, the signal generated when the cooling operation mode is selected is controlled by the control box 11 coupled by the control box coupling device in the rear panel 2 of the air conditioner.

The air sucked into the air conditioner is installed in the air conditioner, and heat exchange occurs in the course of passing through the heat exchanger 5 through which the coolant flows, and the cold air is subjected to the continuous rotation of the cross flow fan 6. It flows along and is guided by the rear guide 7 and the stabilizer 8 provided in the upper rear part in the air conditioner, and is discharged to the outside of the air conditioner.

One end of the elastic member 110 is integrated with the rear panel 2 and the other end is formed with a free end, and the other end of the elastic member 110, that is, the free end, the vertical surface 111a and the inclined surface 111b are integrated. The engaging jaw 111 is formed.

The appearance of the control box 11, that is, the upper and lower cases 101 and 102 is made of a synthetic resin material.

Since the weight of the control box 11 formed of the synthetic resin is reduced, the control box 11 is easily coupled and separated in the rear panel 2.

The process of coupling the control box to the rear panel of the air conditioner by the control box coupling device of the present invention configured as described above is as follows.

First, the control box 11 divided into the upper case 101 and the lower case 102 has a plurality of fastening portions 103 formed on the side of the upper case 101 on the side of the lower case 102. The upper case 101 and the lower case 102 are coupled to each other by being inserted into the plurality of locking units 104. In this case, the control box 11 can be separated without using a separate tool on the rear panel 2. Are combined.

The upper and lower cases 101 and 102 are formed at the lower end of the control box 11, that is, the lower side of the guide 105 integrally coupled to the lower end of the lower case 102 to form a groove 106. In the groove 106, a plurality of guide pieces 107 formed in the rear panel 2 of the air conditioner are fitted with a locking jaw 108 that is bent in a direction opposite to each other, and the locking jaw ( The control box 11 is coupled to the rear panel 2 because the guide 105 slides under the guide piece 107 while the 108 is inserted.

The control box 11 is formed at the front of the guide piece 107, one end is integrated with the rear panel 2, the other end is formed by a free end that is pressed by a small force and is returned to its original position by its own elastic force 110 In this case, the locking jaw 111 is formed at the free end of the elastic member 110, and the inclined surface 111b inclined at a predetermined angle with the vertical surface 111a is integrated in the locking jaw 111. Since the elastic member 110 is placed in a normal position as shown in FIG. 7A before the control box 11 is coupled to the rear panel 2, the control box 11 is a guide piece 107. When guided and slid by the guide 105 of the control box 11 rides the inclined surface 111a of the engaging jaw 111 of the elastic member 110, the elastic member 110 having its own elastic force is shown in Figure 7b Push in the direction of the arrow When the guide of the guide 105 is completed by the guide piece 107, the locking jaw 111 of the elastic member 110 pressed by the guide 105 has its own elastic force as shown in FIG. 7C.
