- The central part 111 is positioned, in a circular form, at the center of the fan 102, that is, the front of a portion to which a driving shaft of the motor is fixed. At this time, the size of the central part 111 may be formed at the center of the fan 102 to be the same as the size of the portion to which the driving shaft of the motor is fixed.
- The discharge grill 11 may be formed at a size overlapped with the fan 102 in the discharge direction of the outdoor air. In other words, when being viewed from the front of the outdoor unit 1, the edge of the fan 102 is shown through the discharge grill 11. On the other hand, when being viewed from the front of the outdoor unit 1, the edge of the fan 102 is shown through the discharge grill 11.
- Meanwhile, the second grill part 113 is extended in the same shape as a trailing edge 109 (see FIG. 1) of the fan 102. In other words, the trailing edge 109 of the fan 102 is extended from the center of the fan 102 to the outside thereof and then extended from the central part 111 of the discharge grill 11 to the outside thereof and is bent and extended in the rotating direction of the fan 102, likewise being bent and extended from the rotating direction of the fan 102
- On the other hand, the second grill part 113 is formed to be tilted based on the rotating orbit of the fan 102. In detail, the second grill part 113 is connected to the central part 111 in a tilted state based on the rotating orbit of the fan 102. In other words, the end of second grill part 113, which is connected to the central part 111, is formed to be tilted based on the rotating orbit of the fan 102.

To the contrary, the tilted angle of the third portion is relatively largest than the tilted angle, the tilted angle of the first portion is relatively smallest, the tilted angel of the second portion is smaller than the tilted angle of the third portion and is larger than the first tilted angle (a < b < c).
- Therefore, the tilted angle of the second grill part 113 has been gradually increased based on the rotating orbit of the fan 102 as a distance is increased from the central part 111 based on the rotating orbit of the fan 102. When viewing the discharge grill from the front, the portion nearer to the central part 111 on the second grill part 113 is positioned in a vertical direction with respect to an eye line and is positioned nearer to a horizontal direction with respect to an eye line as going to the outside. Therefore, when viewing the discharge grill 11 from the front, the portion near to the central part 111 on the second grill part 113 is relatively widely shown and the portion nearer to the edge of the discharge grill 111 is relatively narrowly shown.
- One portion of the second grill part 113 adjacent to the edge of the discharge grill 11 is vertically formed to the rotating orbit of the fan 102. In other words, the end of second grill part 113, which is connected to the edge part 112, is positioned in a vertical state to the rotating orbit of the fan 102.
- With the outer unit 1, the flow resistance of air discharged through the discharge grill 11 can be minimized. In detail, since the second grill part 113 of the discharge grill 11 is formed to be the same as the shape of the trailing edge 109 of the fan 102, the flow resistance occurring while the air, which forcibly flows by the fan 102, passes through the discharge grill 11 can be minimized.
- Since the second grill part 113 is positioned to be tilted based on the rotating orbit of the fan 102, the air, which forcibly flows by the fan 102, can minimize the flow resistance occurring while passing through the discharge grill 11. The reason is that the second grill part 113 of the discharge grill 11 is positioned in a parallel direction with the flow direction of the air passing through the discharge grill 11.
- In more detail, the air passing through the discharge grill flows in a direction that forms a relatively small angle based on the rotating orbit of the fan 102 at a point approaching the central part 111 and flows in a direction that forms a relatively large angle based on the rotating orbit of the fan 102 at a point approaching the edge part 112. The discharge grill 11 of the outdoor unit 1 according to the present invention forms a relatively small tilted angle based on the rotating orbit of the fan 102 at a point approaching the central part 111 and forms a relatively large tilted angle based on the rotating orbit of the fan 102 at a point approaching the edge part 112. Therefore, the discharge grill 11 may be positioned in a parallel direction with the flow direction of air passing through the discharge grill 11. Therefore, the air, which forcibly flows by the fan 102, can minimize the flow resistance occurring while passing through the discharge grill 11.
- In particular, the air, which passes through a point adjacent to the central part 111, flows in a direction that forms a relatively smallest angle to the rotating orbit of the fan 102. In the discharge grill 11 of the outdoor unit 1 according to the present invention, since the ends of the second grill part 113 adjacent to the central part 111 are connected in a state that forms a relatively smallest angle based on the rotating orbit of the fan 102, the flow resistance of air passing through the discharge grill 11 can be more minimized.
- When the flow resistance of air discharged through the discharge grill 11 is minimized, the flow of air passing through the outdoor heat exchanger 101 can be more smoothed. In other words, since the air volume passing through the outdoor heat exchanger 101 can be increased, the heat exchange performance of the outdoor heat exchanger 101 can be more improved.
- All modifications and changes should be construed as being included in the technical scope of the present invention by a person skilled in the art and the right scope of the present invention can be construed based on the appended claims.
