Subsequently, in step S22, the microcomputer 18 determines whether the washing mode selection signal from the washing mode selection unit 10 is a lukewarm washing mode signal. If the washing mode selection mode is not the warm washing mode, the hot water washing mode is selected in step S23. If it is determined whether the hot water washing mode is selected, the microcomputer 18 applies the water supply signal to the water supply valve driver 20 in step S24 to supply the hot water supply control valve 22a of the water supply valve 22 and the cold water supply control valve ( 22b) of the hot water supply control valve 22a is driven by the hot water valve drive signal output from the water supply valve driver 20 to supply the washing water to the washing tank 1 to enable hot water washing, while the hot water washing mode is If it is not selected, the microcomputer 18 determines that the cold water washing mode is selected, and based on the water supply signal output to the microcomputer 18 in step S25, cold water from the water supply valve driver 20 is performed. Cold water washing is possible by supplying the washing water to the washing tank 1 by the cold water valve driving signal for operating only the quick control valve 22b, whereas if the warm washing mode is selected in step S22, the microcomputer 18 in step S26. ) N equals the amount of washing water in the washing tank 1, and in step S27, the microcomputer 18 applies the water supply signal and the water supply control signal to the water supply valve driver 20 to supply the water supply valve 22 to the water supply valve. The hot water supply control valve 22a and the cold water supply control valve 22b are driven on the basis of the valve driving signal output from the driving unit 20 to supply only 1 / n of the washing water to the washing tank 1. do. After that, in step S28, the microcomputer 18 determines whether the water level detection amount detected by the water level detection unit 16 has reached the set washing water level. When the washing water level is not reached at the set washing water level, the washing tank 1 is recovered several times. As it rotates, the supplied hot water and cold water are appropriately mixed to become lukewarm, and in step S30, the temperature detector 14 detects the temperature of the mixed wash water. Subsequently, in step S31, the microcomputer 18 determines whether the detected washing water temperature is within a range of the warm washing temperature stored in the reference temperature memory 12, and when the microcomputer 18 is outside the washing temperature range, the microcomputer 18 in step S32. ) Outputs a water supply control signal and a water supply signal for supplying the water supply to regulate and supply hot and cold water, so that the washing water properly adjusted by the hot and cold water supply control valves 22a and 22b is provided at the water level detection unit 16. After being resupplied to the washing tank 1 by 1 / n by the detected water level detection signal, the process returns to step S28, while the detected washing water temperature does not need to adjust the amount of hot water and cold water if it is within the warm washing temperature range. Therefore, in step S33, the microcomputer 18 outputs a water supply signal and a water level control signal, and the washing water is resupplied by 1 / n through the hot and cold water supply control valves 22a and 22b to step S28. Is returned.
