DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to an electric wire holding structure of an air conditioner.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view and a partially enlarged view of an example of a conventional air conditioner. In the drawing, reference numeral 1 denotes a body of an air conditioner, 2 denotes an outlet provided at an upper portion of a front surface thereof, and 3 denotes a design panel having a remote controller 4 attached to a front surface thereof and a cord clamp 5 provided at a rear surface thereof. Is provided with a heat exchanger 6. Reference numeral 7 denotes a suction port provided in a lower part of the front surface of the design panel 3. A blower 13 equipped with a blower 12, a main body reinforcing member 15 provided below the blower 13 with a code clamp 14 provided below, and an electric component storage box 16 provided above the blower 13 are provided. I have.

In the conventional air conditioner configured as described above, when connecting the remote control cable 17 to the remote control 4, the remote control cable 17 is connected by a connector between the remote control 4 and the electric component storage box 16. One end is connected to a connector (not shown) of the remote controller 4, the remote controller cable 17 guided from the cable outlet 19 a to the back of the design panel 3 is clamped by the code clamp 5, and the other end is connected to the electrical component storage box 16. Connecting.

When connecting the fan motor cable 18, the fan motor cable 18 led out from the fan motor 10 is taken out on the back side of the main body reinforcing member 15, and the cord clamp 14 is connected to the fan motor cable 18.
After being wound and held at an arbitrary position, the other end is connected to the electrical component storage box 16 with a connector.

[0005]

When connecting the remote controller cable 17 of the conventional air conditioner as described above, the remote controller cable 17 may be pulled by a routing operation, and therefore, the connection of the connector 21a of the remote controller 4 is performed. There was a possibility that excessive tension would be applied to the part and the terminal would be disconnected or disconnected, which could lead to equipment failure. Further, since the remote control cable 17 is wound and held at an arbitrary position by the plurality of cord clamps 5, an increase in the number of parts and a reduction in workability cause a cost increase, and the holding of each remote control cable. Position is unclear. Further, after the connector of the remote control cable 17 is connected to the connector, there is a possibility that the terminal may be disconnected or disconnected due to an external tensile force, which may cause a failure of the device.

In connection with the operation of connecting the fan motor cable 18, it is difficult to reliably hold the clamp 14 due to a difference in the winding position and the winding method of the clamp 14.
In addition, there is a problem that the workability is poor. Therefore, the fan motor cable 18 between the clamp 14 and the electric component storage box 16 is easily slackened, and the fan motor cable 18 is drawn in by the static pressure of the blower 13 during operation. As a result, there is a risk of disconnection due to contact with the rotating fan 9.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and simplifies the holding mechanism of the remote control cable and the fan motor cable, thereby reducing the number of holding parts and improving the assembly work of the product, thereby reducing the cost. It is another object of the present invention to provide a highly reliable air conditioner capable of improving product quality and safety.

At this time, the arm-shaped projecting rib 12a is elastically deformed in the direction of arrow 12c as shown by a broken line, and the opening 12b is temporarily enlarged, so that the fan motor cable 18 can be easily inserted into the space 23. Can be inserted. The inserted fan motor cable 18 is pressed by the elastic force of the restored arm-shaped projecting rib 12a, is sandwiched between the fan casing 11 and the arm-shaped projecting rib 12a, and is securely held in the space 23.

Further, when the holding position of the fan motor cable 18 held in the space 23 is changed, the opening 12b is enlarged by elastically deforming the arm-shaped projecting rib 12a in the direction of the arrow 12c as described above. The holding position of the fan motor cable 18 can be easily changed by releasing the holding of the fan motor cable 18 to make it free and moving the fan motor cable 18.
When the fixing work of the fan motor cable 18 is completed,
The other end is connected to the electrical component storage box 16.
