In the operation state of the indoor unit of the air conditioner, the plug 700 plugs the drain port 520 through the plugging section 710. When the condensed water of the drip tray 500 needs to be discharged through the drain port 520, a force can be applied to the insertion and extraction section 720 through the operation hole 721 to remove the blocking section 710 from the drain port 520, exposing the drain port 520, and thereby discharging the condensed water of the drip tray 500 through the drain port 520.

The above-mentioned setting of end cap 700 not only has realized the shutoff to outlet 520, avoids the comdenstion water of water collector 500 to spill over, moreover, the operating hole 721 that end cap 700 set up still does benefit to the operating personnel to exert effort to it to accomplish the plug operation.

In this embodiment, a pagoda-type fitting may be provided at the drain port 520.

In this embodiment, the plugging section 710 is plugged into the drain port 520 to plug the drain port 520, wherein the plug 700 may be made of rubber. In other embodiments, a connection structure adapted to the pagoda-type connector may be provided at the plugging section 710, so as to connect the plug 700 with the drain port 520 and plug the drain port 520.
