To discharge flow-in washing water to the outside of a machine and to prevent the immersion of a blow motor by forming a plurality of drain holes on the base surface of a casing part where the blow motor is fitted.
When abnormality occurs in water level detection and washing water overflows from a blow part 18 in a washing tank, overflowed water flows from the blow port 18 to heater including part 15 and to the casing part 22 where the blow motor is fitted. The casing part 22 is integratedly formed with a plastic base 20 and separated from the other part of the base 20 in a sidewall 23. Therefore, a probability where water flowing into the casing part 22 is not discharged to the outside of the machine but the blow motor is immersed by water exists. Then, the drain holes 24 are formed on the base surface 22 of the casing part to which the blow motor is fitted so that the machine is constituted to discharge water to the outside of the machine, which overflows from the blow port 18 in the washing tank. The plurality of drain holes 24 are formed to be the small ones so that the intrusion of cockroaches is prevented.
