Now, in the above-described configuration, if water splashes onto the top surface of the operation box 6, water will leak out from the gap between the water flow switching knob 18 and the peripheral edge of the opening 16 in the panel 8, as indicated by the arrow in FIG. However, it may get into the operation box 6.
Since the flange 18a on the outer periphery of the knob 18 is brought close to the periphery of the opening 16 from below, the amount of water intruding into the operation box 6 through the gap can be suppressed as much as possible. When water enters the operation box 6 through the gap, the water flows along the top surface of the mounting portion 9a of the mounting plate 9, and flows into the washing tub 3 from the water drain port 23 through the water inlet 25. It will leak out. At this time, since the cylindrical rib 22 is formed at the peripheral edge of the opening 15 in the mounting plate 9, water will not come into contact with the washing timer 11. Also,
If the front part of the operation box 6 is exposed to water, water may enter the operation box 6 through the guide hole 35 of the panel 6, but the support part 9b of the mounting plate 9 and the rising wall 37 of the base 7 Since the guide hole 35 is located opposite to the guide hole 35, water does not enter the washing timer 11 side, but flows out from the drain hole 38 of the base 7 into the washing tub 3.

On the other hand, even if the water in the washing tank 3 overflows due to, for example, a drain hose becoming clogged when water is being supplied to the washing tank 3, so-called abnormal overflow occurs, the base 7 is designed to surround the washing timer 11 and the spin-drying timer 19. Since the rising wall 37 and the upper end of the water inlet 25 are set higher than the upper end of the washing tub 3, water overflowing from the washing tub 3 does not hit the washing timer 11 and the spin-drying timer 19. There isn't.

Further, according to the above-described configuration, the washing timer 11 and the dehydration timer 19 can be arranged close to the upper surface of the base 7, so that the height of the operation box 6 can be suppressed and the panel can be made low.

Furthermore, drain, water supply, and overflow levers 32, which are slide levers, are provided on the support portion 9b formed in the front part of the mounting plate 9, respectively.
, 33 and 34 are attached, and their attachment portions are covered by the panel 8, so that waterproofness for the washing timer 11 and spin-drying timer 19 can be ensured, and the appearance does not deteriorate.
