The operation panel is connected with the clamping part 23 of the key frame body 20 through a buckle to realize the installation on the base body 10, water scattered by the operation panel falls into the key frame body 20, the water flow is collected at the inner side edge of the key frame body 20 under the action of gravity, in addition, the water flow collected at the inner side edge of the key frame body 20 is collected to the water outlet 21 and is arranged in the diversion trench 30 through the first diversion surface 22; the water dropped on the outside of the key frame 20 is collected by the second guide groove 32, guided to the water passage opening 33, and discharged through the second guide surface 34 from the water passage opening 33 and the second guide groove 32.

When the water amount is large, the water flow can be guided into the first diversion trench 31 through the upper curved surface 341 of the second diversion surface 34, so that the water drainage is realized; when the water flow is small, the surface tension of the water can make less water difficult to flow in the second diversion trench 32 with a large cross section, and by arranging the second diversion arc surface 36 connected with the second diversion surface 34, the water firstly converges in the second diversion arc surface 36 under the action of gravity after dropping in the second diversion trench 32 and converges in the lower curved surface 342 of the second diversion surface 34, and when the water converges sufficiently, the water can be discharged into the first diversion trench 31, and the water remaining in the second diversion arc surface 36 can flow in the first diversion arc surface 35, so that the water discharge is realized.

In addition, by arranging the first guide surface 22, the second guide surface 34, the first guide arc surface 35 and the second guide arc surface 36, a water flow stagnation phenomenon caused by surface tension is avoided, so that water is better discharged.

Other configurations and operations of the laundry treating apparatus according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
