However, when the discharge pipe 196 is directly exposed to the atmosphere, the smell, moisture, etc. contained in the wet air may be discharged into the atmosphere, which may be unpleasant to the user.

Although not shown in the drawing, the discharge pipe 196 may be connected to a drain hose (not shown) for draining the wash water during washing or rinsing so that the wet air discharged through the discharge pipe 196 may be discharged through the drain hose.

Meanwhile, in the case of a drain hose, a trap having a “U” shape may be formed in order to prevent odor or the like from flowing backward. At this time, the discharge pipe 196 is preferably connected to the rear end of the trap because the wet air may not be discharged by the trap.

It describes the operation of the air discharge structure according to an embodiment of the present invention as described above. The effect of the air discharge structure of the present invention is to be exerted during the drying process of the washing apparatus (100). Thus, the description of the washing stroke, rinsing stroke, etc. of the washing apparatus 100 will be omitted and will be briefly described only for the drying process associated with the present invention. Meanwhile, each of the elements mentioned below should be understood with reference to the above description and drawings.

First, as the drying process proceeds, the blowing fan 163 of the air supply device 160 is operated, and the air inside the tub 120 is sucked through the air recovery port 161 according to the operation of the blowing fan 163. , By the blowing fan 163 is moved to the heating duct 164 side. Accordingly, the air moved to the heating duct 164 is heated by a heating heater (not shown) provided in the heating duct 164, and is supplied into the tub 120 through the air discharge port 165.

The air supplied into the tub 120 dries the laundry inside the tub 120 (specifically, the drum 130). The air drying the laundry is changed into wet air by the moisture evaporated from the laundry and is circulated through the air recovery port 161.

Meanwhile, the wet air introduced into the tub 120 through the blowing fan 163 in the above-described process is temporarily stayed in order to dry the laundry in the tub 120. The humid air temporarily staying in the tub 120 is forcibly discharged to the outside of the tub 120 by the exhaust unit 190 provided in the exhaust unit 129.

That is, the wet air staying in the tub 120 is forcibly sucked by the exhaust fan 191 of the exhaust unit 190 connected to the exhaust unit 129 and extruded into the exhaust pipe 192. Accordingly, the wet air extruded into the exhaust pipe 192 is discharged to the outside of the washing apparatus 100 through the exhaust pipe 192. As part of the humid air is discharged in this process, the relative humidity of the humid air is lowered, and the laundry can be dried without changing a condensation structure into dry air.

Therefore, according to the air discharge structure according to an embodiment of the present invention by discharging a part of the wet air contained in the air during the drying administration of the laundry to the outside of the washing apparatus 100 can lower the humidity of the air without a separate condensation structure There is an effect, which has the effect of effectively drying the laundry.

In addition, if a separate condensation structure is provided, the moisture contained in the humid air can be more easily removed, so it is natural that the laundry can be dried more effectively.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, The present invention may be modified in various ways. Therefore, modifications of the embodiments of the present invention will not depart from the scope of the present invention.
