An air conditioner is a device that circulates a compressor, a condenser, an expansion valve, and an evaporator to condition air, and the air conditioner 1 described above refers only to an indoor unit. In order for the air conditioner to form a refrigeration cycle and circulate the refrigerant, a refrigerant pipe connecting the indoor unit and the outdoor unit is required.

The refrigerant pipe 200 may connect the heat exchanger 50 installed inside the air conditioner 1 to a compressor installed outside the air conditioner 1. In order to form a cycle in which the refrigerant circulates, the refrigerant pipe 200 may include an inlet pipe 202 into which the refrigerant enters and an outlet pipe 204 from which the refrigerant after heat exchange is released. The inlet pipe 202 and the outlet pipe 204 may be coupled to the heat exchanger 50 located above the main body 110 and extend downward. Therefore, in FIG. 3 showing a side cross-section of the air conditioner 1, the refrigerant pipe 200 is shown as one.

The refrigerant pipe 200 extending downward is a connector 210 provided at the rear of the air conditioner 1, and the inlet pipe 202 and the outlet pipe 204 are combined to escape to the outside of the air conditioner 1. have. The refrigerant pipe 200 exiting the air conditioner 1 may pass through a wall of the indoor space and be connected to an outdoor unit located in the external space to form a refrigeration cycle.

As such, since one side of the refrigerant pipe 200 is fixed to the heat exchanger 50 and the other side extends to the outside of the air conditioner 1 and is connected to the outdoor unit, the degree of freedom of installation of the air conditioner 1 is limited. Can occur.

As described above, the air conditioner 1 changes the installation structure of the blade plates 12c, 22c, 32c, disk plates 12a, 22a, 32a, and grills 12b, 22b, 32b to prevent the discharged air. Wind direction and air volume can be adjusted. However, this method is controlled from the design stage of the air conditioner 1, and there is a problem that it cannot be applied flexibly depending on the indoor space to be conditioned. Further, simply changing the shape of the diffusers 12, 22, 32 cannot fundamentally change the direction of the discharged air.

Accordingly, the air conditioner 1 may include a rotating unit 100 that supports and rotates the main body 110 in order to fundamentally change the direction of the discharged air. The rotating unit 100 and the main body 110 are provided to be detachably provided as separate assemblies and can be mounted as needed. The main body 110 is seated on the rotating unit 100 and rotates to discharge air in different directions into the indoor space.

The refrigerant pipe 200 may be provided as a flexible refrigerant pipe so as to move elastically as the main body 110 rotates. The flexible refrigerant pipe expands and contracts a certain length and moves flexibly, thereby securing a degree of freedom in which the main body 110 can rotate.

The refrigerant pipe 200 may include a'U'-shaped trap 212 to secure a margin for expansion and contraction. At least one trap 212 may be provided in the refrigerant pipe 200 so that the refrigerant pipe 200 can move freely according to the rotation of the main body 110.

The connector 210 may include guide surfaces 214 and 216 attached by blocking the connector 210 so as to be removable. The guide surfaces 214 and 216 are attached to be easily detachable by contacting at least one or more of the connector 210.

First, the second guide portion 216 of the guide surfaces 214 and 216 may be removed to form the central sphere 218 at the center of the connector 210. By installing the refrigerant pipe 200 through the central hole 218, when the main body 110 does not operate, the refrigerant pipe 200 may be located at the center of the connector 210. Thereafter, the second guide part 216 is removed to expose the connector 210 extending horizontally, and the refrigerant pipe 200 may move left and right from the connector 210 as the body 110 rotates.
