The drain portion 300 may include a drain cap 310 and a first inclined rib 320. The drain cap 310 extends in the first direction and is provided with a condensate water inlet 311 connected to the receiving part 400 and the connecting hose 430 at the upper end, and the condenser 210 on one side. An open surface 312 is formed in communication with and a wall surface 313 may be provided on the other side opposite to the open surface 312. For example, the drain cap 310 may have the shape of a hollow square pillar surrounded by three walls excluding the open surface 312.

Meanwhile, the condenser 210 includes a plurality of fins 211 stacked in a first direction, and the plurality of fins 211 may be aluminum fins. At this time, the gap in the first direction between the plurality of pins 211 may be about 1.2 mm to 1.5 mm, and the space between the plurality of pins 211 may be open and communicate with the open surface 312. .

Accordingly, the window-type air conditioner with a condensate removal function according to an embodiment of the present invention directs condensate falling in the first direction through the condensate water inlet 311 in the second direction through the open surface 312. It can be injected into the condenser 321. More specifically, the condensed water flowing into the drain cap 310 may be injected between the plurality of fins 211 through the open surface 312, and the condenser ( 210) can continue to move toward the inner side. At this time, the condensed water is vaporized as it exchanges heat with the heated condenser 210 and can be discharged outdoors, so the condensed water generated in the evaporator 110 can be easily removed.

The first inclined rib 320 is provided with one end 320a in contact with the open surface 312 inside the drain cap 310, and has a first inclined surface 321 formed to be inclined upward toward the wall surface 313. may include. Accordingly, the condensate flowing in through the condensate water inlet 313 can be guided toward the open surface 312 along the first inclined surface 321.

Furthermore, the drain portion 300 is provided inside the drain cap 310 to be spaced apart from the first inclined rib 320 in the first direction, and one end portion 330a is spaced apart from the open surface 312. and may further include a second inclined rib 330 formed to be inclined upward toward the wall surface 313.

However, since the second inclined rib 330 is provided with the open surface 312 and one end 330a spaced apart from each other, the condensate falling on the second inclined rib 330 is connected to the one end 330a. ) can fall downward.

In other words, the first inclined rib 320 may serve to inject condensate between the plurality of fins 211, and the second inclined rib 330 may flow from the first inclined rib 320. It serves to buffer overflowing water and allow it to fall downward.

Meanwhile, the first inclined rib 320 and the second inclined rib 330 may have different inclination angles, which are the degree of inclination from the second direction parallel to the ground, for example, the first inclined rib 320 The inclination angle may be greater than the inclination angle of the second inclined rib 330. Accordingly, the condensate falling on the second inclined rib 330 may be transferred to the open surface 312 at a slower rate than that of the first inclined rib 320.

In addition, the second inclined rib 330 has one end 330a spaced apart from the open surface, and the other end 330b is closer to the wall surface than the end 320b of the adjacent first inclined rib 320. 313). More specifically, the end 320b on the wall surface 313 side of the first inclined rib 320 and the end 330b on the wall surface 313 side of the second inclined rib 330 are spaced at a predetermined distance ( d) may be spaced apart. Accordingly, condensate overflowing between the first inclined rib 320 and the open surface 312 can stably fall on the second inclined rib 330.

At this time, a plurality of the first inclined ribs 320 and the second inclined ribs 330 may be provided alternately along the first direction inside the drain cap 310. For example, the side adjacent to the condensate inlet 311 is connected to the first inclined rib 320 and the second inclined rib 330, and to the first inclined rib 320 and the second inclined rib 330. Assuming that the adjacent sides are the second first inclined rib 320 and the second inclined rib 330, the condensate falling on the first inclined rib 320 is the first inclined surface 321 and the open surface 312. ) and can be injected between the plurality of pins 211 through the open surface 312. In addition, the condensate overflowing in excess of the space between the first inclined rib 320 and the open surface 312 is connected to the first second inclined rib 330 provided to be spaced apart from the first inclined rib 320. It can fall and move toward the open surface 312, and can fall and be accommodated in the space between the first and second inclined ribs 320 and the open surface 312 along the second inclined rib 330. Condensate water can be continuously injected between the plurality of fins 211 through the second first inclined rib 320, similar to the first inclined rib 320. Therefore, the window-type air conditioner 10 according to an embodiment of the present invention can simultaneously inject condensate into the plurality of fins 211 through the plurality of first inclined ribs 320, thereby increasing condensate removal efficiency. You can.

In addition, the first inclined rib 320 further includes a first buffer surface 322 that is bent at one end of the first inclined surface 321 and extends toward the wall surface 313 along a direction parallel to the second direction. This can be done, and in this case, the other end of the first inclined surface 321 may be provided to contact the open surface 312. The first buffering surface 322 may serve as a buffer when condensate accumulates between the first inclined surface 321 and the open surface 312 and overflows. That is, even if condensate accumulates to one end of the first slope 321 and overflows, the first buffer surface 322 can serve to buffer the condensate from falling downward for a certain period of time, and in addition, the condensate can It may serve as a guide so that it can fall stably on the second inclined rib 330.

Figure 6 shows a cross-sectional view of the drain portion according to the second embodiment of the present invention.

Referring to FIG. 6, the first inclined rib 300 may further include a second buffer surface 323 extending from the open surface 312 toward the wall surface 313 along a direction parallel to the second direction. The first inclined surface 321 may be formed by bending one end of the second buffering surface 323, and the other end of the second buffering surface 323 may be provided in contact with the open surface 312. there is. That is, the drain unit 300 according to the second embodiment of the present invention can expand the space in which condensate is accommodated between the first inclined rib 320 and the open surface 312, and can stably accommodate the condensate. It can be easily injected between the plurality of pins 211. That is, the drain unit 300 according to the second embodiment has a second buffer surface 323 parallel to the fins 211, thereby lowering the pressure and facilitating condensation water between the plurality of fins 211. It can be injected.

Furthermore, the first inclined rib 320 may further include a second inclined surface 324 formed by bending an end of the first inclined surface 321 to be inclined downward toward the wall surface 313 . Accordingly, the second inclined surface 324 directs condensate flowing in excess of the space between the first inclined surface 321 and the second buffer surface 323 and the open surface 312 to the second inclined rib 330. It can guide you to fall safely.

According to the structure of the window-type air conditioner 10 according to an embodiment of the present invention described above, condensed water generated in the evaporator 110 can be removed by flowing into the condenser 210, and is disposed on one side of the condenser 210.
