After that, it may scatter into the internal space of the container 112 through the hole 114b. Water scattered during this process may flow into the interior of the recovery duct 140 through the connection part 141 connected to the top of the container 112. Since the trap 150 can collect water flowing into the recovery duct 140 as described above, the air flow within the recovery duct 140 is smoothed, drying performance is improved, and more water is added inside the recovery duct 140. A hygienic environment can be created and the problem of water infiltrating the heat pump 122 and causing the heat pump 122 to malfunction can be prevented.

Referring to FIGS. 6 and 7 , in one embodiment, the lower surface of the second duct portion 143 may be formed to be inclined toward the trap 150.

For example, the lower surface of the second duct portion 143 may be formed to protrude at least partially in a direction toward the trap 150 at a location in contact with the trap 150. For example, the lower surface of the second duct portion 143 is curved in a direction that protrudes toward the trap 150, or has an inclined surface (e.g., inclined to protrude relative to a specific axial direction within the trap). A first inclined surface and a second inclined surface) may be formed.

Specifically, based on the upper surface of the second duct part 143, the upstream part of the lower surface of the second duct part 143 (e.g., first slope) on the air flow may be formed to slope down along the air flow. And, the downstream portion of the lower surface of the second duct portion 143 above the air flow (e.g., the second inclined surface) may be formed to slope downward along the air flow.

In this way, by forming the lower surface of the second duct portion 143 to be inclined toward the trap 150, water passing through the second duct portion 143 can be more easily collected toward the trap 150. For example, even if the water that has passed through the second duct portion 143 is not immediately captured by the trap 150 while passing through the first slope, it may flow into the trap 150 while passing through the second slope.

Trap 150 may include a discharge port 151. Water collected inside the trap 150 may be discharged from the trap 150 through the discharge port 151.

The discharge port 151 may be formed at the lower end of the trap 150. For example, the discharge port 151 may protrude laterally from the lower end of one of the sides of the trap 150. Through this, all of the water collected inside the trap 150 can be discharged to the outside of the trap 150 without remaining. As shown in FIGS. 5 to 7 , the discharge port 151 may be formed to protrude downward from the trap 150.

The discharge port 151 may be formed on the side closest to the drainage pump 124. Specifically, the water collected in the trap 150 can be discharged to the outside of the clothing treatment device 100 using the drain pump 124, which discharges the water collected in the condenser, so the discharge port 151 is connected to the drain pump. It may be advantageous to form on the side closest to (124).

Referring to FIG. 6, the lower surface of the trap 150 may be formed to be inclined toward the discharge port 151. Through this, the water collected in the trap 150 can flow to the discharge port 151 due to the gradient of the lower surface of the trap 150, so the water collected in the trap 150 effectively flows through the discharge port 151. It can be released through

The clothing processing device 100 may include a cover 160 . The cover 160 may be formed to cover the top of the trap 150. The cover 160 may be formed to be approximately continuous with the lower surface of the second duct portion 143 adjacent to the trap 150. Through this structure of the cover 160, it is possible to prevent vortices from being formed by the internal space of the trap 150, which is formed discontinuously with the internal flow path of the second duct part 143, and thereby improve drying efficiency. You can.

Referring to FIG. 7, the first edge 161, which is an upstream edge in the air flow direction of the cover 160, may be formed continuously with the lower surface of the second duct portion 143 adjacent thereto. Through this, the air flowing inside the second duct portion 143 can smoothly flow along the upper surface of the cover 160 to the next area of the trap 150.

Meanwhile, in one embodiment, at least a portion of the second edge 162 corresponding to the downstream edge in the air flow direction of the cover 160 may be placed higher than the lower surface of the second duct portion 143 adjacent thereto. Accordingly, a step may be formed between the second edge 162 and the lower surface of the second duct portion 143.

For example, the upper edge of the trap 150 may have at least a portion of the upstream edge higher than the downstream edge in the air flow direction, and the first edge 161 of the cover 160 may be formed by a second duct adjacent thereto. Since the cover 160 can be arranged horizontally while being formed continuously with the lower surface of the cover 160, there is a step between the lower surface of the second duct part 143 in contact with the second edge 162 of the cover 160. can be formed.

The cover 160 may include an opening 166 composed of a plurality of holes 167. The opening 166 is connected to the second duct portion 143. The trap 150 can be connected. Water flowing into the second duct portion 143 may flow into the trap 150 from the second duct portion 143 through the opening 166. Various shapes of the opening 166 will be described later with reference to FIG. 11 .

Referring to FIGS. 7 to 10 , the cover 160 may include a side portion 163. The side portion 163 may be formed by a step formed between the second edge 162 of the cover 160 and the lower surface of the second duct portion 143. That is, the side portion 163 may be understood as a side wall portion of the cover 160 exposed to the internal flow path of the second duct portion 143 due to a step.

A gap 164 may be formed between the side portion 163 and the lower surface of the second duct portion 143. Referring to FIGS. 7 and 9, among the water that has passed through the second duct portion 143, the water that has passed the trap 150 portion flows back toward the trap 150 (i.e., due to the slope of the lower surface of the second duct portion 143). , upstream direction) can flow down. In this way, the water flowing down the lower surface of the second duct part 143 enters the inside of the trap 150 through the gap 164 formed between the side part 163 and the lower surface of the second duct part 143. may flow into.

Cover 160 may include a support portion 165. The support portion 165 may extend downward from the side portion 163. The support portion 165 may be formed in plural numbers and may be arranged in a direction crossing the air flow direction. The support portion 165 may divide the gap 164 into a plurality of parts. The support portion 165 can compensate for structural weaknesses that occur due to the gap 164 being formed between the second edge of the cover 160 and the lower surface of the second duct portion 143.

Referring to FIG. 5 , the clothing treatment device 100 may include a discharge pipe 170 . The discharge pipe 170 may connect the drainage pump 124 and the discharge port 151. As described above, the water collected in the trap 150 can be shared with the drain pump 124, which discharges the water collected in the condenser, and for this purpose, the discharge pipe 170 is a discharge port formed in the trap 150 ( 151) and the drainage pump 124 can be connected.

Figure 11 shows various aspects of the opening 166 formed in the cover 160.

Referring to FIG. 11, the opening 166 may include a plurality of holes 167 extending in a direction intersecting the air flow direction. The plurality of holes 167 may be arranged in the direction of air flow. Through this structure, water flowing into the second duct portion 143 can be better captured by the trap 150 when it moves in the direction of air flow.

For example, referring to (A) of FIG. 11, the opening 166 may be formed in a shape in which holes 167 extending in a direction intersecting the air flow direction are arranged in the air flow direction.

In addition, referring to (B) of FIG. 11, the opening 166 has at least one plurality of holes 167 extending in a direction crossing the air flow direction arranged in a direction crossing the air flow direction, and these plurality of holes 167 are arranged in a direction crossing the air flow direction.
