First, when the operation is started after setting the process contents by the setting means 9, the process control means 8 inputs water level information from the water level detection means 10, and operates the water supply valve 7 to supply water into the tank 2 until a predetermined water level is reached. Next, the process control means 8 drives the motor 5 to rotate the stirring blade 3. After a predetermined period of time has elapsed, the motor 5 is de-energized, the number of waveforms from the voltage detection means 11 is input to the cloth amount determining means 12, and compared with the cloth amount determination reference value to determine the amount of cloth in the washing tub 1. do. Here, the method of determining the amount of cloth by the amount of cloth determining means 12 will be explained. In this embodiment, the amount of cloth is determined and divided into four stages, and the number of waveforms from the voltage detection means 11 is divided into four membership functions A to D corresponding to the amount of cloth as shown in FIG. If the number of waveforms is Pa, the membership value of membership function A is 0.25, and the membership value of membership function B is 0.75. FIG. 4 shows the configuration of the cloth amount determining means 12, which is a hierarchical type in which input layer units Uia to Uid corresponding to the membership functions, output layer units Uoa to Uod corresponding to four levels of cloth amounts, etc. are combined. It is composed of a signal processing section 12a which is a neural network, and a cloth amount determining section 12b. In this configuration, the membership function is determined by the threshold value i of the distribution of the amount of cloth and the number of waveforms, which is determined by experiment in advance as shown in FIG.
The membership values of the corresponding membership functions are input to the input layer units Uia to Uid of the signal processing unit 12a.For example, when the number of waveforms is Pa as described above, , 0 to input layer unit Uia
．． 25, 0.75 is input to unit Uib, and 0 is input to other input layer units. Note that the unit "1" is a unit for learning the offset value of each unit, and is a unit that always outputs 1. In addition, the coupling coefficient between each unit of the neural network, the offset value of the unit, etc. are initialized by learning using the data of the amount of cloth and the number of waveforms obtained through this experiment as training data. The determining section 12b of the cloth amount determining means 12 is the signal processing section 12.
Determine the output values of the output layer units Uoa to Uod of a,
It is determined that the amount of cloth corresponds to the output layer unit with the largest output. Here, if the user of the washing machine is dissatisfied with the amount of cloth determined by the above process, for example, if the determination result of the amount of cloth of the washing machine is medium, the water level in the washing tub 1 will be adjusted according to the amount of cloth. If the user of the washing machine feels that the water level is low relative to the amount of clothes when the washing machine is set to "medium", the set water level is changed to "high" by the water level setting means 9a. The process control means 8 controls subsequent processes in accordance with this set water level. The cloth amount determining means 12 re-learns the number of output waveforms of the voltage detecting means 11 at this time and the cloth amount corresponding to the set water level changed by the user of the washing machine as training data.

くなる。As described above, according to the embodiment, the cloth amount determining means 12
The reference value for determining the amount of cloth is held as a neural network coupling coefficient and an offset value of the unit, and is updated by learning sequentially based on the data corrected by the water level setting means 9a by the user of the washing machine, so that the reference value for determining the amount of cloth is always maintained. The value follows the actual amount of cloth, and the user of the washing machine no longer has to correct the reference value for determining the amount of cloth each time.

Any device that detects a physical quantity correlated to the amount of cloth inside the cloth may be used. Further, although the neural network of this embodiment uses a three-layer structure, the cloth amount determining means may also be configured with a neural network having a multi-layer structure such as four layers.
