Description

Air conditioner

Technical Field

The present invention relates to an air conditioner, and more particularly, to an air conditioner that generates condensed water.

Background

An air conditioner is a device that cools, heats, or purifies indoor air sucked in, and supplies the cooled indoor air to a room.

The air conditioner may be installed in a window, and may suck indoor air to exchange heat, then supply the air to the indoor space, and may suck outdoor air to exchange heat, and then discharge the air to the outdoor space. In the case of such a window air conditioner, an indoor fan and an indoor heat exchanger for flowing indoor air are disposed inside the casing, and an outdoor fan and an outdoor heat exchanger for flowing outdoor air are disposed outside the casing.

However, the conventional air conditioner has a problem that it is difficult to remove condensed water generated in the heat exchanger. In particular, in the case of an air conditioner installed in a window, since the casing is located between the indoor space and the outdoor space, there is a problem in that it is difficult to drain condensed water to the outside of the casing. Therefore, the condensed water remaining inside the casing not only reduces the performance of the air conditioner but also generates malodor.

In addition, the conventional air conditioner has a problem in that heat exchange performance is deteriorated due to overheating of the condenser during the continuous driving. The conventional air conditioner has a problem that the heat exchange performance cannot be prevented from being lowered because it has no means for reducing the temperature of the overheated condenser.

A portion of the outer peripheral wall of the upper port 522 may be located between the inflow port 511a and the port inflow port 524. Accordingly, the condensed water flowing into the split space 512 through the inflow port 511a is prevented from directly flowing into the split hole 521, and thus the condensed water can be uniformly dispersed in the plurality of split ports 520.

The description of the downstream port 520b above may be similarly used to describe other downstream ports 520c, 520d, 520e.

The upstream port 520a may have a tap hole 521. The condensed water in the split space 512 may be discharged to the condenser 42 through the split hole 521.

Upstream port 520a may include an upper port 522. The upper port 522 may protrude toward the diverting space 512. The tap hole 521 may be located inside the upper port 522. The upper port 522 may be cylindrical in shape. An end of the upper port 522 may be spaced from the diverter sidewall 518.

The upstream port 520a may include a port inflow port 524. A port inflow port 524 may be formed between the diverter sidewall 518 and the upper port 522. The above description of the port inflow port 524 of the downstream port 520b may be equally applicable to the description of the port inflow port 524 of the upstream port 520 a.

The upper port 522 of the upstream port 520a may include a first perimeter wall 522a. The first peripheral wall 522a may have an arc shape.

The upper port 522 of the upstream port 520a may include a second peripheral wall 522c. The second peripheral wall 522c may have an arc shape. The second perimeter wall 522c may be integrally formed with the first perimeter wall 522a. The height of the second peripheral wall 522c may be less than the height of the first peripheral wall 522a.

The upper port 522 of the upstream port 520a may include a step 522b. The step 522b may connect the first and second peripheral walls 522a and 522c. The step 522b may have a height corresponding to the height difference D of the first and second peripheral walls 522a and 522c.

The upstream port 520a may have a first height H1. The downstream port 520b may have a second height H2. The height H1 of the upstream port 520a may be greater than the height H2 of the downstream port 520 b. The first height H1 of the upstream port 520a may refer to the height of the first peripheral wall 522 a.

The first peripheral wall 522a may be opposite to the inflow port 511 a. The condensed water flowing in through the inflow port 511a can flow along the first peripheral wall 522a toward the second body 515.

A port inflow port 524 of the upstream port 520a may be formed between the second peripheral wall 522c and the splitter side wall 518.

By making the height of the upstream port 520a disposed closest to the inflow port 511a larger than the height of the downstream port 520b, it is possible to prevent the condensed water flowing in through the inflow port 511a from concentrating on the upstream port 520 a.

The air conditioner 1 will be described with reference to fig. 15.

Fig. 15 is a cutaway perspective view of the shunt 500 cut in a vertical direction.

The condensed water flowing into the split space 512 through the inflow port 511a can spread into the split space 512 along the periphery of the upstream port 520 a.

The height H1 of the first peripheral wall 522a may be greater than the height H2 of the second peripheral wall 522 c. The first and second peripheral walls 522a and 522c may have a height difference D.

The height H2 of the second peripheral wall 522c may be the same as the height of the downstream ports 520b, 520c, 520d, 520 e.

The lower port 523 may protrude from the diverter body 510 to the lower side and be connected to the condenser 42.

The condensed water in the split space 512 may flow into the split port 520 through the port inflow port 524. The condensed water flowing into the split port 520 may flow downward through the split hole 521 (refer to fig. 14). The condensed water flowing downward through the flow dividing hole 521 may be discharged to the condenser 42 through the lower port 523.

The air conditioner 1 will be described with reference to fig. 16.

Fig. 16 is a cutaway perspective view of the shunt 500 cut in a vertical direction.

The upper port 522 may protrude upward from the diverter lower wall 519. The lower port 523 may protrude downward from the diverter lower wall 519.

The condensed water in the diverting space 512 can flow into the diverting holes 521 through a port inflow port 524 formed between the diverter sidewall 519 and the upper port 522. The condensed water flowing into the diverting holes 521 may flow downward toward the lower port 523. The condensed water flowing into the lower port 523 can be discharged to the condenser 42 through the port discharge port 525.
