Group, the coefficient (a, b) of above-mentioned mathematical expression (1) is found out using multidimensional least square method, and updates the presumption letter of presumption motor temperature T
Number.Then, control unit 54 is calculated based on newer function again reaches in the wash time that motor 14 is set in step s 2
Temperature Te is reached, and updates and reaches temperature Te (step S11).
Then, control unit 54 is after update reaches temperature Te, return to step S7, is washed based on newer arrival temperature Te changes
Wash the setting of running flow.
Later, until the wash time by setting in step s 2, the following operation repeatedly of control unit 54：That is, every
Motor temperature (step S10) is measured by minute (step S9), and is opened obtained data are measured every time with washing operation
It is beginning to obtain later, is added with the data group of motor temperature T by time X, it is electric based on the data group update presumption for being added gained
The presumption function of machine temperature T and arrival temperature Te (step S11), and according to the setting of newer arrival temperature Te change flows
(step S7).
Then, (judging result of step S8 is "Yes"), control unit when have passed through the wash time set in step 2
54 terminate washing operation, into dehydrating operation.
