Each tables of data D11~16 are for each washing weight and respectively to the value and vibration exported from vibrating sensor 22
Dynamic sensor 22 provides the relationship that the unbalanced load amount caused by water drum 13 is inferred as in the case where value output.It loses
Weighing apparatus load can for example be indicated by the eccentric load of the rotary shaft relative to roller 15.In this case,
Such as each tables of data D11~16 are made in the following manner.
That is, counterweight etc. is for example set to the inner peripheral surface of roller 15 and forms eccentric load in roller 15 by operator, and
And washings is configured in roller 15.In this case, so that total weight of counterweight and washings reach predetermined weight,
Such as 2kg, 4kg, 6kg, 8kg, 10kg.Next, operator acts driving mechanism portion 16 and roller 15 is rotated,
Thus dehydration process is executed.Moreover, operator is practical in dehydration process being that specific rotation speed in high speed rotation carries out
Measurement carries out actual measurement to the output valve of the vibrating sensor 22 in first interval and second interval in this case.
Moreover, operator for investment to the washings in roller 15 weight, roller 15 formed unbalanced load amount,
The output valve of the vibrating sensor 22 actually read and at the time of read the output of vibrating sensor 22 under rotation speed with
Record their modes of being mutually related.Operator makes each tables of data D11~16 in the above described manner.
In this case, first interval be since dehydration process until reaching steady rotation speed during
Set any section.In addition, second interval is during from first interval until reaching steady rotation speed
Set any section.That is, the rotation speed in second interval is faster than the rotation speed in first interval.In this case,
First interval and second interval are set as not overlapping.In addition, steady rotation speed refer in dehydration process in addition to accelerate and
The rotation speed in section other than deceleration interval, and be to be finally reached and maintain constant rotation speed within a certain period of time
Degree.
Such as shown in Fig. 5, steady rotation speed, that is, steady rotation speed in the process of dehydration is set as the feelings of 800rpm
Under condition, first interval R1 is set as the section of such as 300rpm~400rpm, second interval R2 be set as such as 500rpm~
The section of 600rpm.In addition, the specific value of steady rotation speed, first interval and second interval permitting according to washing machine 10
Xu Liang, steady rotation speed etc. and change, therefore, if suitably set according to the particular provisions of washing machine 10, and
It is not limited to above-mentioned numerical value.
First inference process shown in Figure 2 portion 33 is able to carry out the first inference process.As shown in Fig. 5~Fig. 8, first is pushed away
Disconnected processing is to handle as follows: first set by during from dehydration process until reaching steady rotation speed
In the R1 of section, the unbalanced load amount of water drum 13 is inferred based on the vibratory output detected by vibrating sensor 22.Such as by correcting
Processing unit 32 selects the tables of data D11 in Fig. 3, when the value of the vibratory output detected in first interval R1 by vibrating sensor 22
When for " 6000 ", the first inference process portion 33 infers are as follows: water drum 13 produces the unbalanced load of " 400g " in first interval R1
Amount.
In addition, the second inference process shown in Figure 2 portion 34 is able to carry out the second inference process.As shown in Fig. 5~Fig. 8,
Second inference process is to handle as follows: set during from first interval R1 until reaching steady rotation speed
In second interval R2, the unbalanced load amount of water drum 13 is inferred based on the vibratory output detected by vibrating sensor 22.Such as by
Correction process portion 32 selects the tables of data D11 in Fig. 3, when the vibratory output detected in second interval R2 by vibrating sensor 22
Value be " 2000 " when, the second inference process portion 33 infer are as follows: water drum 13 produces the unbalance of " 600g " in second interval R2
Load.
Load difference calculation processing unit 35 is able to carry out load difference calculation processing.Load difference calculation processing is
Following processing: it subtracts from the unbalanced load amount for the second interval R2 being inferred to by the second inference process portion 34 by the first inference process
The unbalanced load amount for the first interval R1 that portion 33 is inferred to and calculate unbalanced load amount difference S.Unbalanced load amount difference S is indicated
The trend that unbalanced load amount increases and decreases with the increase of the rotation speed of roller 15.
That is, unbalanced load amount difference S is positive value, it is meant that with the increase of the rotation speed of roller 15, roller 15 is produced
Raw unbalanced load amount reduces.I.e., it is meant that vibrate the trend being eliminated caused by the water drum 13.On the other hand, it loses
Weighing apparatus load difference S is negative value, it is meant that with the increase of the rotation speed of roller 15, unbalanced load amount caused by roller 15
Also increase.I.e., it is meant that the trend of increase is vibrated caused by the water drum 13.
Rotation speed adjustment processing unit 36 is able to carry out rotation speed adjustment processing.As shown in Fig. 5~Fig. 8, rotation speed
Adjustment processing is to handle as follows: based on by the calculated unbalanced load amount difference S of load difference calculation processing unit 35 come to the
The rotation speed of two section R2 later roller 15 is adjusted.In this case, rotation speed adjustment is handled
Portion 36 carries out control as follows: slowing down the later roller 15 of second interval R2 with unbalanced load amount difference S negative trend side
Steady rotation speed.
For example, in this case, as shown in figure 5, initial steady rotation speed is for example set as
800rpm.Herein, in the case where unbalanced load amount difference S is, for example, 300g or more, it is believed that the institute in first interval R1
The unbalance of generation is substantially eliminated in second interval R2.Therefore, as shown in Figures 4 and 5, rotation speed adjusts processing unit 36
It is constant that the steady rotation speed of the rotation speed later as second interval R2 is remained into 800rpm.
It on the other hand, is, for example, 0g or more and in the case where less than 300g in unbalanced load amount difference S, it is believed that
It is generated in one section R1 unbalance to be slightly eliminated in second interval R2.In this case, make the rotation of roller 15 after
It is continuous to carry out, thus, although it is possible to generating vibration because unbalance, but the dehydration of the washings in roller 15 carries out so that unbalance
A possibility that further eliminating is also higher.Therefore, in this case, as shown in Fig. 4 and Fig. 6, rotation speed adjusts processing unit 36
The steady rotation speed of the rotation speed later as second interval R2 is adjusted to unbalanced load amount difference S to be 300g or more
Example compare and slightly lower 700rpm.Thereby, it is possible to inhibit the vibration because caused by unbalance, and can be by carrying out roller 15
The dehydration of interior washings and realize unbalance further elimination.
In addition, unbalanced load amount difference S for example less than 0g and be -300g or more in the case where, it is believed that first
It is generated in the R1 of section unbalance slightly to increase in second interval R2.In this case, when continuing the rotation of roller 15, though
It so is also possible to generate vibration because unbalance, but makes unbalance elimination there is also the progress of the dehydration of the washings in roller 15
A possibility that.Therefore, in this case, as shown in Fig. 4 and Fig. 7, rotation speed adjustment processing unit 36 will be used as second interval R2
The steady rotation speed of later rotation speed is adjusted to 600rpm compared with above-mentioned 2 examples and slower.Thereby, it is possible to press down
System vibration because caused by unbalance, and can be attempted by carrying out the dehydration of the washings in roller 15 by unbalance elimination.
For above-mentioned example, in the case where unbalanced load amount difference S such as deficiency -300g, it is believed that in the firstth area
Between generated in R1 unbalance substantially increase in second interval R2.In this case, unbalance even if continuing the rotation of roller 15
A possibility that a possibility that being eliminated is relatively low, another aspect, and bigger vibration is generated because unbalance is higher.Therefore, at this
In the case of, as shown in Figures 4 and 8, the later rotation speed of second interval R2 is set as by rotation speed adjustment processing unit 36
0rpm and the rotation of roller 15 is stopped.
In addition, the relationship of unbalanced load amount difference S shown in Fig. 4 and steady rotation speed is an example of present embodiment,
It is not limited to above-mentioned example.I.e., it is possible to according to the allowance of washing machine 10, particular provisions etc. and suitably to unbalanced load amount
The relationship of difference S and steady rotation speed changes.
In addition, for the relationship of unbalanced load amount difference S and steady rotation speed, steady rotation speed is set in Fig. 4
