部8cを有するものである。In FIG. 1, reference numeral 1 denotes a cloth amount detecting means, which is a kind of A / A that converts the electromotive force of the motor 4 that changes according to the cloth amount applied to the stirring blade 5 when the motor 4 shifts from the ON state to the OFF state into a pulse number. This is a D conversion means, which is usually constituted by a photocoupler or the like. The characteristic of the cloth amount detecting means 1 is that, when the electromotive force is small, that is, when the cloth amount applied to the stirring blade 5 is large, the number of pulses is reduced. Reference numeral 2 denotes a nonvolatile memory, which holds data even when the control circuit is not energized, and allows the data to be changed by the setting key 3. Reference numeral 8 denotes a microcomputer which controls a water supply valve 6, a drain valve 7, a motor 4, and a non-volatile memory 2;
This causes the washing machine to perform a series of operations of washing, rinsing, and dehydrating, and has an input unit 8a, an output unit 8b, and an arithmetic control unit 8c inside.

This will be described with reference to FIG. 3 and FIG. In FIG. 2, when the laundry amount detecting step is started, the microcomputer 8 turns on / off the motor 4 at step 10 and turns on at step 11
Then, the number of electromotive force pulses when the motor is off is integrated. Next, at step 12, it is determined whether or not the above steps 10 to 11 have been repeated N times. During that time, the number of pulses is sequentially accumulated. After repeating N times, the microcomputer 8 returns to step 13
Predetermined data previously input from the nonvolatile memory 2 is input, and in step 14, the integrated pulse number P is corrected based on the data, for example, P '= P + 10. The relationship between the accumulated pulse and the cloth amount is as shown in FIG. 3, and based on the correction data P ',

P 'large amounts of if step 17, K 1 ≦ P'<if K 2, medium amount of step 18, if K 2 ≦ P ', determines that a small amount of the step 19. According to the above embodiment, by correcting the integrated pulse P based on the data in the non-volatile memory 2, the cloth amount detection reference can be changed. The setting key 3 for inputting data in the non-volatile memory 2 is provided with the function of the setting key 3 by simultaneously pressing a washing time key, a water flow key, and the like 27, and can also be used as a key.
