Basically, as shown in FIG. 4, washing-first rinsing-second
Rinse-dehydration process is performed in the order of
At the time of water supply in each of the washing step, the first rinsing step, and the second rinsing step, as shown in FIG. 5, first, the water supply valve 30 is intermittently energized, and the water supply valve 33 is continuously energized. As a result, water is intermittently injected from the water supply valve 30 to the transmittance sensor 23, especially the translucent windows 26 and 27, from the water inlet 28 through the connection hose 29, and the impact of the water causes the translucent windows 26 and 27 to intermittently inject water.
The dirt is removed from each surface of 27.

当てることができ、透過度センサ２３の汚れを効果的に
取除くことができる。In this case, since the water injection device 31 mainly including the water supply valve 30 is configured to inject water with the water inlet 28 facing the transmittance sensor 23, water can be directly applied to the transmittance sensor 23. Thus, the dirt on the transmittance sensor 23 can be effectively removed.

透過度センサ２３を最初から汚れにくくもできる。The portion where the transmittance sensor 23 is located is
Above the cap 13 that closes the opening 12 on the lower surface of the air trap 10, this is where dirt or soap scum contained in the washing water in the outer tub 2 is less likely to come.
The transmissivity sensor 23 can be hardly stained from the beginning.

Many impacts of water can be given to the surface, and dirt can be more effectively removed.
【００２４】そして一方、第１すすぎ行程，第２すすぎ

り、その金属石けんの付着を防止することができる。On the other hand, at the time of each dehydration of the first rinsing step, the second rinsing step and the dehydrating step, as shown in FIG.
From the beginning, the water supply valve 30 is continuously energized, and the water supply valve 33 is not energized. As a result, water is continuously injected into the transmittance sensor 23 to prevent dirt from adhering to the surfaces of the light transmitting windows 26 and 27. In particular, when powdered soap is used for washing, sodium of the powdered soap component dissolves in water and combines with magnesium in tap water, resulting in fine-grained metallic soap that does not dissolve in water. The rotation of the inner tank 4 causes the outer tank 2 to fly, and the transmittance sensor 23
Is usually attached to the light-transmitting windows 26, 27, but by continuously injecting water into the transmittance sensor 23 as described above, the adhesion of the metallic soap can be prevented.

る。Also, at this time, since the water injection device 31 has the water injection port 28 facing the transmittance sensor 23 and directly irrigates the water, the dirt can be prevented from adhering to the transmittance sensor 23. The effect can be obtained more reliably.
【００２６】更に、透過度センサ２３が位置したキャッ

にできる。In addition, the transmittance sensor 23 disposed on the cap 13 can be incorporated at the same time by the operation of closing the opening 12 on the lower surface of the air trap 10 with the cap 13. Since a special assembling work is not separately required for assembling, the work can be easily performed.

The water injection device 37 replaces the water injection device 31 described above by forming the forked end of the liquid crystal device 5 into a water injection port 36 and individually facing the light transmitting windows 26 and 27 of the transmittance sensor 23. By doing so, it is possible to more effectively remove dirt from the light-transmitting windows 26 and 27 and to prevent adhesion of dirt.
