Embodiment of the axial coupling is not limited to this, for example, there is a configuration that the groove is formed on the side of the floating disk plate 33b, the coupling coupled to the rotating coupling portion 35b rotating blade 35b. .

Since the rotation of the flow blade rotating shaft 35bb is made, it may cause a change in the air flow of the discharged air. When the plurality of floating blades 35b are divided into four equal parts with respect to the horizontal line and the vertical line with respect to the front of the indoor unit 10, they are positioned in the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant clockwise from the upper right. This allows each control by the controller (not shown) to rotate the rotating blade rotating shaft (35bb). Through this, it is possible to control the amount and flow rate of the discharged air blown up, down, left and right.

The flow grill 34b is disposed in an annular shape on the extension line of the fixed grill 34a at the front of the fixed grill 34a, whereby the discharge air blown from the vortex fan 38 is discharged through the discharge port 31. The discharge air flow is prevented from spreading up, down, left, and right at the time of discharging the front of the front side and serves to guide the discharged air.

The grill 34 may include a blade 35, and may adjust the wind direction and the air volume of the air discharged through the discharge port 31 by adjusting the number of blades, the shape, or the arrangement angle of the blade 35.

As shown in Figs. 1 to 6, the blade 35 is formed in the shape of a spiral blade from the disc plate 33 to the grill 34, thereby guiding the discharge air blown out of the drift fan 38. To be discharged to the outside. The blade 35 includes a floating blade 35b of the floating diffuser 32b and a fixed blade 35a of the fixed diffuser 32a.

The grille 34 is formed in an annular shape. As a result, the discharge air blown from the swirl fan 38 is prevented from being diffused up, down, left, and right when the front of the front panel 100 is discharged through the discharge port 31, and guides the discharge air. The grill 34 includes a floating grill 34b of the floating diffuser 32b and a fixed grill 34a of the fixed diffuser 32a.

In addition, by adjusting the distance between the disc plate 33 and the grill 34 to reduce or increase the radial width of the discharge port 31, the wind direction and the air volume of the air discharged through the discharge port 31 may be adjusted, The direction of the air and the amount of air discharged through the discharge port 31 may be adjusted by adjusting the diameter of the plate 33.

The drive motor 37 is coupled to the rear surface of the disc plate 33 so that the rotation shaft 37a is disposed in the direction toward the rear panel 110 to drive the swirling fan 38 to rotate.

The four-flow fan 38 is disposed between the diffuser 32 and the heat exchanger 50 to suck the air exchanged heat in the heat exchanger 50 to be discharged through the discharge port 31, the drive motor 37 The hub 38a is coupled to the rotating shaft 37a of the plurality of blades, and includes a plurality of wings 38b coupled to the outer circumferential surface of the hub 38a.

The diameter of the hub 38a is provided to gradually decrease in the direction toward which the rotational shaft 37a of the drive motor 37 faces, that is, toward the rear panel 110. The outer circumferential surface of the hub 38a is provided to be inclined so that the air sucked into the swirling fan 38 can be discharged inclined toward the discharge port 31.

At least three wings 38b are spaced at equal intervals along the outer circumferential surface of the hub 38a. The wing 38b forms a pressure gradient in the front and rear directions of the vortex fan 38 in the process of rotating together with the hub 38a to form a constant air flow.

The duct 40 is coupled to the rear surface of the diffuser 32 and forms a flow path 39 that moves in the process of discharging the air sucked by the crossflow fan 38 to the discharge port 31.

The duct 40 is formed in a circular shape surrounding the drift fan 38 and is disposed in the side portion of the drift fan 38, and an inner diameter of the flow path is formed so that the side is inclined so as to increase from the rear side of the duct 40 to the front side. Flow passage diffusion tube 40b which is disposed in front of the forming tube 40a and the flow channel forming tube 40a and has an inclination inclined more outward than the inclination of the flow channel forming tube 40a so that suction air can be discharged inclined. ), A fixing plate 40c connected to the rear of the flow path forming tube 40a to fix the duct 40 in the housing 20.

The diffuser 32 is coupled and fixed to the inlet front of the flow path diffusion tube 40b, and the duct 40 is coupled to and fixed to the fixed frame 60 through a fixed plate 40c formed in a square shape.

The heat exchanger 50 is disposed between the four-flow fan unit 30 and the suction port 111 formed in the rear panel 110 to absorb heat from the air introduced through the suction port 111 or flow in through the suction port 111. Transfer heat to air. The heat exchanger 50 includes a tube 51 and a header 52 coupled to the upper and lower sides of the tube 51.

The inlet 111 is provided on the rear panel 110 disposed at the rear of the heat exchanger 50 to guide air outside the indoor unit 10 to flow into the indoor unit 10.

The grille 34 and the discharge port 31 may have a rectangular shape or may be changed in some cases. However, in the present embodiment, the grill 34 and the discharge port 31 may be circular.

In addition, although the arrangement of the discharge port 31, the swirl fan 38, the heat exchanger 50, and the suction port 111 may be changed according to the design change, the air conditioner can be made slimmer and the discharge air is discharged. It may be characterized in that arranged in a line in the front and rear direction of the housing 20 to improve the capacity.

The following describes the operation of the present invention by the above configuration.

The air sucked in the inlet 111 located at the rear of the heat exchanger 50 unit absorbs or loses heat while passing through the heat exchanger 50 unit. Air that exchanges heat while passing through the heat exchanger (50) unit is sucked by the swirling fan (38) and proceeds through the duct (40) to the outlet (31), which is a space between the grill (34) and the disc plate (33). do.

In detail, the air discharged from the vortex fan 38 is guided by the fixed diffuser 32a disposed in front of the vortex fan 38, and externally flowed through the flow diffuser 32b disposed in front of the fixed diffuser 32a. Discharged.

As the flow disk plate 33b of the floating diffuser 32b rotates, the flow velocity changes as the first position A and the second position B change, and the flow blade rotating shaft coupled to the flow disk plate 33b.
