4 and 5, the heat exchanger 50 is located between the suction portion 15 and the orifice 13. The orifice 13 is located between the heat exchanger 50 and the blower 14. The suction part 15 is located ahead of the heat exchanger 50 and the orifice 13.

A heat exchanger 50 is located behind the suction part 15, an orifice 13 is located behind the heat exchanger 50, and a blower 14 is located behind the orifice 13, and the blower ( A fan motor 14a is located at the rear of 14).

The discharge portion 16 may be located rearward of the heat exchanger 50 and the orifice 13. At least a portion of the blower 14 may be positioned to vertically overlap the discharge portion 16.

The drain pan 100 is located below the heat exchanger 50 and collects condensed water that falls from the heat exchanger 50. The drain pan 100 vertically overlaps the heat exchanger 50 and may have a width wider than the width of the heat exchanger 50.

For example, the drain pan 100 includes a first drain member 101 located ahead of the heat exchanger 50, a second drain member 102 located behind the heat exchanger 50, and a first drain. It may include a third drain member 103 connecting the lower ends of the member 101 and the second drain member 102.

Condensed water dropped from the heat exchanger 50 flows along the space between the first drain member 101 and the second drain member 102.

Of course, the drain pan 100 may further include a fourth drain member 104 that is located between the first drain member 101 and the second drain member 102 and supports the heat exchanger 50.

FIG. 6 is a perspective view of the orifice 13 in FIG. 4, FIG. 7 is a perspective view showing the orifice 13 in FIG. 4 from a direction different from that of FIG. 6, and FIG. 8 is a longitudinal cross-sectional view of the orifice 13 in FIG. 6.

The structure of the orifice 13 will be described in detail with reference to FIGS. 5 to 8.

The orifice 13 guides the air introduced from the suction unit 15 to the blower 14, reduces the pressure of the air introduced from the suction unit 15, and provides it to the blower 14.

The orifice 13 may include a main body 133 and a guide hole 131. The main body 133 may have a size that covers at least the suction part 15 and the heat exchanger 50. The cross-sectional area of the main body 133 may be larger than the cross-sectional area of the heat exchanger 50.

The orifice 13 may further include a heat exchanger receiving portion 137 that accommodates the heat exchanger 50. The heat exchanger receiving portion 137 may have a shape that protrudes forward from the main body 133 and surrounds the heat exchanger 50. The heat exchanger receiving portion 137 may have a shape surrounding the guide hole 131.

Accordingly, the heat exchanger 50 is accommodated between the front of the main body 133 and the inner surface of the heat exchanger accommodating portion 137. The heat exchanger 50 is fixed to the orifice 13.

In addition, the orifice 13 may further include a pipe holder 136 that secures a connection pipe that supplies refrigerant to the heat exchanger 50. The pipe holder 136 protrudes from the main body 133 and may have a hook structure or an elastic structure into which a connecting pipe is inserted. The pipe holder 136 is located away from the guide hole 131 in the main body 133.

In addition, the orifice 13 may further include an electric field partition 134 that limits interference between the electric field part 2 and the blower 14 located at the top of the orifice 13. The full-length partition 134 may have a structure that protrudes rearward from the top of the main body 133 and covers the upper part of the blower 14.

The guide hole 131 has a smaller cross-sectional area than the suction part 15 and the heat exchanger 50 and is formed through the main body 133. The guide hole 131 depressurizes the air flowing in through the suction unit 15 and guides it to the blower 14.

The guide hole 131 may have a circular shape. Specifically, the guide hole 131 may have a circular shape centered on the rotation axis (Ax) of the blower 14.

The cross-sectional area of the guide hole 131 may decrease in the direction from the suction part 15 to the blower 14. The orifice 13 surrounds the guide hole 131 and may further include a guide edge 132 protruding rearward from the main body 133.

The guide edge 132 may define the boundary of the guide hole 131. The guide edge 132 has a ring shape and may be inclined toward the rotation axis (Ax) of the blower 14 toward the rear.

In the process of cooling the air by the heat exchanger 50, condensate water accumulates in the heat exchanger 50, and this condensate flows from the heat exchanger 50 toward the blower 14 due to the pressure of the blower 14. , condensed water flowing into the blower 14 may be discharged through the discharge port. In order to solve this problem, the orifice 13 of the present invention further includes a condensate water inflow prevention portion 135.

The condensate inflow prevention unit 135 prevents condensed water generated in the heat exchanger 50 from flowing into the discharge unit 16.

The condensate inflow prevention portion 135 may protrude from the bottom of the guide hole 131 to the center of the guide hole 131. If the condensate water inflow prevention part 135 protrudes too much, the amount of air flowing in through the guide hole 131 is reduced, thereby reducing the efficiency of the heat exchanger 50, and if the condensate water inflow prevention part 135 is too small, the efficiency of the heat exchanger 50 is reduced. If it protrudes, it will not be able to prevent the inflow of condensate.

Therefore, it is preferable that the upper end of the condensate inflow prevention unit 135 is located higher than the lower end of the heat exchanger 50. When the top of the condensate inflow prevention unit 135 is located higher than the bottom of the heat exchanger 50, condensate generated in the heat exchanger 50 due to gravity is collected at the bottom of the heat exchanger 50, so this condensate flows into the orifice. The inflow to the bottom of (13) can be restricted.

The height of the upper end of the condensate inflow prevention unit 135 may be lower than the center of the guide hole 131 and higher than the lower end of the heat exchanger 50. Preferably, the upper end of the condensate water inflow prevention unit 135 may have a height of 5% to 15% compared to the height of the center of the guide hole 131 based on the lower end of the guide hole 131.

The top of the condensate inflow prevention unit 135 may extend horizontally in the left and right directions. The upper end of the condensate inflow prevention unit 135 may define a predetermined fan-shaped chord centered on the lower end of the guide hole 131.

In the case of the bottom of the guide hole 131, it is located slightly higher than the bottom of the heat exchanger 50, so condensate can flow in through the bottom of the guide hole 131, but the portion other than the bottom of the guide hole 131 is Since the height is sufficiently higher than the bottom of the heat exchanger 50 so that condensate cannot flow in, a condensate water inflow prevention portion 135 is formed at the bottom of the guide hole 131.

The condensate inflow prevention unit 135 may be located at a position that vertically overlaps the guide hole 131 or the rotation axis (Ax) of the blower 14. The condensate inflow prevention unit 135 may be located rearward of the heat exchanger 50 and forward of the blower 14. The condensate inflow prevention unit 135 may be placed rearward of the drain pan 100.

Therefore, the lower end of the main body 133 is located lower than the lower end of the heat exchanger 50, the lower end of the guide hole 131 is located higher than the lower end of the heat exchanger 50, and the condensate inflow prevention unit 135 The upper end is located higher than the lower end of the guide hole 131.

Of course, the second drain member 102 of the drain pan 100 may be located rearward than the lower end of the main body 133 of the orifice 13, and the first drain member 101 and the fourth drain member 104 ) may be located ahead of the bottom of the main body 133. Through this structure, part of the condensate falling into the drain pan 100 is prevented from flowing into the space between the drain pan 100 and the lower end of the main body 133.

The condensate inflow prevention portion 135 may extend from the bottom of the guide hole 131 upward, but may have various structures to effectively prevent condensate inflow.

For example, the condensate inflow prevention part 135 includes a first prevention part 135a extending from the guide hole 131 toward the center of the guide hole 131, and a first prevention part 135a at one end of the first prevention part 135a. It may include a second prevention part 135b extending in a direction intersecting the prevention part 135a.

The second prevention portion 135b may protrude from one end of the first prevention portion 135a in the direction in which the heat exchanger 50 is located.

Specifically, the first prevention part 135a extends upward from the bottom of the guide hole 131, and the second prevention part 135b may protrude forward from the top of the first prevention part 135a. The first prevention part 135a may extend from the bottom of the guide hole 131 upward, and the second prevention part 135b may extend from the top of the first prevention part 135a in a direction between the front and top. there is.

Therefore, the condensate inflow prevention part 135 includes a first prevention part 135a extending upward, and a second prevention part 135b protruding from the top of the first prevention part 135a toward the indoor unit, Even if the condensate condensed at the bottom of the indoor unit flows into the lower part of the orifice 13 due to air flow, it is primarily blocked by the first prevention part 135a, and the condensate is prevented from flowing into the upper part of the first prevention part 135a by air pressure. Even if it flows, there is an advantage that the inflow of condensate can be suppressed by the second prevention part (135b).

The condensate inflow prevention unit 135 is located between the heat exchanger 50 and the blower 14, and is positioned to overlap the bottom of the heat exchanger 50 in the front-back direction.

The orifice 13 may further include a drain seating portion 139 that prevents condensate from the drain pan 100 from flowing toward the blower 14.

The drain seating portion 139 may be in contact with the drain pan 100. Specifically, the drain seating portion 139 may be located in front of the second drain member 102 of the drain pan 100 and may be in contact with the front surface of the second drain member 102.

The drain seating portion 139 includes a first seating member 139a extending downward from the guide edge 132 and a second seating member 139b protruding rearward from the first seating member 139a. 2 The seating member 139b may be in contact with the second drain member 102.

The top of the second drain member 102 may be in contact with the guide edge 132. Accordingly, condensed water from the drain fan 100 is prevented from flowing through the second drain member 102 toward the blower due to air flow, etc.

The display panel 30 and the cabinet 10 can be moved relative to each other by a link. The link may include a connecting link 3a.

The connection link 3a is hingedly connected to the display panel 30 and the cabinet 10, respectively. The connecting link 3a includes a first link 331, one end of which is hinged with the cabinet 10, one end of which is hinged with the first link 331, and the other end of which is hinged with the display panel 30. May include link 332. The length of the second link 332 may be longer than the length of the first link 331. A link motor (3b) may be connected to the connection link (3a).

When the display panel 30 is in an open state, the first link 331 and the second link 332 are spread apart to form an obtuse angle with each other. When the display panel 30 is in an open state, the angle between the first link 331 and the second link 332 is preferably 150 to 180 degrees.

When the display panel 30 is closed, the first link 331 and the second link 332 are folded at an acute angle to each other. When the display panel 30 is closed, the angle between the first link 331 and the second link 332 is preferably 1 degree to 30 degrees.

Figure 9 is a diagram showing the movement of condensate according to an embodiment of the present invention.

Referring to FIG. 9, when the indoor unit is operated, the heat exchanger 50 exchanges heat with the air flowing in through the suction part 15, and the air heat exchanged in the heat exchanger 50 is discharged through the blower 14. It flows out to unit 16.

The condensate (S) generated in the heat exchanger (50) aggregates and moves downward due to the viscosity and surface tension between gravity and the condensate, and this condensate falls on the drain pan located below the indoor unit.

The condensate that accumulates at the bottom of the indoor unit and some of the condensate that falls from the indoor unit to the drain pan (100) move in the direction of the blower (14) by the air flow, and the condensate flows back to the drain pan (135) from the condensate inflow prevention unit (135). 100).

Figure 10 is a cross-sectional view of the orifice 13-1 according to another embodiment of the present invention.

Compared to the embodiment of FIG. 8, the orifice 13-1 according to another embodiment of the present invention has a difference in the structure of the condensate water inflow prevention portion 135-1. In the condensate water inflow prevention unit 135-1 according to another embodiment, the second prevention unit 135b is omitted compared to the embodiment of FIG. 8. Hereinafter, the description will focus on the differences from the embodiment of FIG. 8, and configurations without special explanation will be considered the same as the embodiment of FIG. 8.

Referring to FIG. 10, the condensate water inflow prevention unit 135-1 according to another embodiment may include only the first prevention unit 135a. If the height of the top of the first prevention part 135a is sufficiently high, the inflow of condensate can be prevented only with the first prevention part 135a.

Figure 11 is a cross-sectional view of the orifice 13-2 according to another embodiment of the present invention.

Compared to the embodiment of FIG. 8, the orifice 13-2 according to another embodiment of the present invention has a difference in the structure of the condensate inflow prevention portion 135-2.

Referring to FIG. 11, the condensate water inflow prevention unit 135-2 according to another embodiment may extend from the bottom of the guide hole 131 between the upper and front sides. That is, the condensate inflow prevention unit 135-2 may have an inclination with respect to the vertical direction.

Additionally, the condensate inflow prevention unit 135-2 may have a round shape. The condensate inflow prevention unit 135-2 may have a rearward convex shape.

Therefore, the height of the condensate inflow prevention portion 135-2 is low, so that the inflow of condensate can be effectively prevented without reducing the amount of air flowing into the guide hole 131.
