Through setting up first connecting portion 8 and second connecting portion 9, make between first breakwater 601 and the second breakwater 602, there is the clearance between second breakwater 602 and the trigger end, when making washing machine upper cover 1 close, the drop of water that first breakwater 601 top was gathered is from between first breakwater 601 and the second breakwater 602, the terminal surface of keeping away from pivot 4 along first breakwater 601 falls, the drop of water that second breakwater 602 top was gathered is from between second breakwater 602 and the trigger end, the terminal surface of keeping away from pivot 4 along first breakwater 601 falls, further prevent that the drop of water from flowing to trigger portion 7. By arranging the second drain hole 11 and the third drain hole 12, when the washing machine upper cover 1 is closed, water drops accumulated on the tops of the first water baffle 601 and the second water baffle 602 flow down along the end surfaces of the first water baffle 601 and the second water baffle 602 and are drained in time, and the water drops are prevented from being accumulated again.

Preferably, in this embodiment, the bottom of the first water baffle 601 extends beyond the bottom of the protrusion 5, the first drainage holes 10 are arranged along the length direction of the protrusion 5, a plurality of rib plates 13 extending from the bottom of the protrusion 5 to the bottom of the first water baffle 601 and arranged in parallel are arranged between the middle of the bottom of the protrusion 5 and the first water baffle 601, and the gaps between the rib plates 13 are in one-to-one correspondence with the first drainage holes 10, so that the rib plates 13 guide the flow direction of the accumulated water discharged from the first drainage holes 10.

Second breakwater 602 is connected on first breakwater 601, second breakwater 602 bottom continues to extend, trigger part 7 is connected in second breakwater 602 and is kept away from the bottom of 4 side end faces of pivot, thereby further increase the difference in height at trigger part 7 and first breakwater 601 top, prevent that the drop of water that first breakwater 601 and second breakwater 602 top were gathered from dripping on trigger part 7, the protective effect of reinforcing breakwater 6, make trigger part 7 remain dry throughout, the reliability of the work of reinforcing trigger part 7.

In this embodiment, through setting up first breakwater 601 and second breakwater 602, the ponding to bellying 5 is blockked and is discharged, prevents ponding to trigger part 7, guarantees the drying of trigger part 7 to guarantee the accuracy of acting between trigger part 7 and micro-gap switch 14, increase micro-gap switch 14's life simultaneously.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
