Abstract: PROBLEM TO BE SOLVED: To improve handleability by stopping the operation of a motor for driving a pump in the case that the suction of bath water by an automatic motor driven water suction pump is impossible even after the lapse of a fixed time at the time of operating the automatic motor driven water suction pump. SOLUTION: The bath water sucked to the water suction chamber of the pump 26 is sent through a runner to an air-water separation chamber and supplied through a bath water ejection pipe to the inside of a washing tank. In this case, when the current of the motor for driving the pump is equal to or less than 1 ampere for instance, whether or not the current of the motor for driving the pump is equal to or more than 0.3 ampere for instance is detected and whether or not two minutes elapse after starting the operation of the motor for driving the pump is detected since it is equal to or less than 0.3 ampere for instance immediately after starting the motor for driving the pump because air is still enveloped in.  In the case that the current of the motor for driving the pump is equal to or less than 0.3 amphere even after the lapse of two minutes, it is considered that the bath water runs out in the middle of the suction and energizing to the motor for driving the pump is turned OFF.

Abstract: PURPOSE:To execute a calculation without depending on the control of an external hardware even at the time of using a general register, in which an arithmetic result is undertermined, as an input value by utilizing a number to indicate an input source and a number to indicate an output destination in input data. CONSTITUTION:First input data are held in input registers 2a and 2b, and the input source register number and output destination register number in the input data are held in input source tag registers 11a and 11b and an output destination tag register 12. When second input data use the arithmetic result of the first input data, the output of comparator 13a or 13b goes to 1, and a standby signal is outputted from a terminal 15. The calculation by the second input data is made to temporarily stand by, the arithmetic result by the data inputted beforehand is returned to the input register 2a or 2b, and the calculation is executed by an arithmetic part 3. Thus, even in the case of using the general register, in which the arithmetic result is undetermined, as the input value, the calculation can be executed without depending on the control of the external hardware.
