選択しかできなかった。Conventional technology There is a conventional method for determining the amount of laundry, but it requires correction due to differences in the machine's washing tub size, motor torque, mechanical tenacity, etc., and it is necessary to use multiple input terminals. Alternatively, a selection method using a matrix using a combination of a plurality of output terminals and input terminals has been used. An example of this is shown in FIG. In Fig. 3, 34 is a digital input section, which is provided with four input terminals, each with a jumper wire J3.
0 to 33 and a series body of resistors R30 to R33 were connected. And either jumper wire 130-3
By connecting jumper wires 3 to 3, the comparison calculation processing section 36 determines which jumper wires 30 to 33 are connected and performs correction. However, in a control device using such a 4-bit microcomputer, only 4 to 16 types can be selected using 4 terminals, and only 2 types can be selected using 1 input terminal. .

めてなされることである。Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is a block diagram showing a cloth amount determining device in an embodiment of the present invention. In the figure, 1 is an analog value generation means for selecting a correction value, 2 is an analog value input section, 3 is an A-D converter that converts the analog value into a digital signal, 4 is a storage section, and 5 is a cloth amount discrimination in the storage section. The numerical value group 6 is a numerical value group for cloth amount discrimination correction and has a correlation with the digital numerical value inputted by the A-D converter 3. 7 is a detection means for determining the amount of cloth, and a numerical value corresponding to the amount of cloth is inputted to the comparison calculation processing section 8. When determining the amount of cloth, it is compared with a predetermined numerical value group 6 for determining the amount of cloth to determine which of a plurality of levels the amount of cloth is in. However, there is no problem in the case of only models, but due to differences in models, differences in motor torque, etc., it becomes necessary to modify the discriminant value numerical group for discrimination by similar comparison calculations. Here, in the present invention, a standard value is determined in the comparison calculation to select only the correction value according to the analog input value, and the correction value selected as the standard value is compared with the cloth amount generation input value, and correction is performed. A 4-bit A-D converter with only one input terminal can obtain 16 types of correction values. With 8 bits, 256 correction values can be obtained, but this can only be achieved by having an AD converter.
