Then, the duplicate description of those configurations may be omitted. As used herein, "based on XX" means "based on at least XX" and may include cases based on other factors in addition to XX. Further, "based on XX" is not limited to the case where XX is directly used, and may include the case where it is based on a case where calculation or processing is performed on XX. As used herein, the term "XX or YY" is not limited to the case of only "XX" or only "YY", and may include both cases of "XX" and "YY". This is also the case when there are three or more selective elements. "XX" and "YY" are arbitrary elements (for example, arbitrary information).

FIG. 1 is a diagram showing a configuration example of the washing system 1 of the embodiment. The washing system 1 includes, for example, a washing machine main body 10, an operation panel 20, and a learning device 30. The washing machine main body 10 includes a washing tub 110, a drive unit 120, an acceleration sensor 131, a weight sensor 132, a cloth quality determination unit 133, and a washing control unit 140. The operation panel 20 includes a display unit (notification unit) 210 and an input unit 220. The learning device 30 includes a state information acquisition unit 311, a state determination unit 312, an evaluation information acquisition unit 313, a learning unit 314, a clothing type estimation unit 315, and a storage unit 320.

The washing machine main body 10, the operation panel 20, and the learning device 30 may be integrally configured as a washing machine. Alternatively, the washing machine main body 10, the operation panel 20, and the learning device 30 may be configured as two or more devices. For example, the operation panel 20 may be configured as a remote controller separate from the washing machine main body 10. Alternatively, the operation panel 20 may be configured by using a mobile terminal device such as a smartphone. Alternatively, the operation panel 20 may be configured by using a computer such as a personal computer (PC) or a tablet terminal device (Tablet). Alternatively, the display unit (notification unit) 210 and the input unit 220 may be configured by a voice dialogue device such as a smart speaker instead of the operation panel 20. Further, the learning device 30 may be configured as a server device (for example, a cloud server on an external network) that provides a learning function regarding the operation of the washing machine main body 10.

The washing system 1 performs a washing operation, a rinsing operation, a dehydration operation, and a drying operation by the washing machine main body 10 according to an operation course selected by the user, or an operation of the washing machine main body 10 that executes a part of these operations to perform washing. The user's evaluation of the laundry will be reflected in the next and subsequent washings. Specifically, the washing system 1 acquires the user's evaluation for the operation of the washing machine main body 10, and the setting contents of the driving course (for example, various operation parameters and threshold values) so as to reflect the evaluation result in the next and subsequent washings. , Or operating time). An example of the threshold value is a threshold value for performing error determination (for example, determination of offset error described later) in the dehydration operation, but the threshold value is not limited to this.

The washing machine main body 10 performs a washing operation, a rinsing operation, a dehydrating operation and a drying operation, or a part thereof, according to an operation course selected by the user. The operation of the washing machine main body 10 to perform a washing operation, a rinsing operation, a dehydrating operation and a drying operation, or a part thereof is also referred to as an operation of the washing machine main body 10.
The user's evaluation of the operation of the washing machine body 10 includes an evaluation of the degree of stain removal of the laundry, an evaluation of the remaining amount of the laundry detergent, an evaluation of the degree of dehydration of the laundry, and an evaluation of the degree of wrinkle of the laundry. It may include a user's evaluation of the finish of the laundry, such as an evaluation of the dryness of the laundry. Further, in the user's evaluation of the operation of the washing machine main body 10, the evaluation of the magnitude of the vibration (noise) of the washing machine main body 10, the evaluation of the input amount of the washing treatment agent (detergent or softener) by the automatic charging machine, and the water supply. An evaluation of the operation itself of the washing machine main body 10, such as an evaluation of the amount (water charge), may be included. Further, the user's evaluation of the operation of the washing machine main body 10 may be an evaluation for one washing (one operation) or an evaluation for a certain period (for example, one month).

The washing tub 110 accommodates laundry. When the washing machine main body 10 is configured as a drum type washing machine, the washing tub 110 may be a drum. When the washing machine main body 10 is configured as a vertical washing machine, the washing tub 110 may be a rotary tub.
The drive unit 120 includes, for example, a motor connected to the washing tub 110 to rotate the washing tub 110. The motor may be able to rotate the stirrer (pulsator) at the bottom of the washing tub 110.

In the washing operation, for example, water and detergent are added to the washing tub 110 containing laundry such as clothes, and the driving unit 120 rotates the washing tub 110 to remove the dirt on the laundry. In the rinsing operation, after draining the water containing the detergent, water is added to the washing tub 110, and the drive unit 120 rotates the washing tub 110 to remove the detergent. In the dehydration operation, the drive unit 120 rotates the washing tub 110 to dehydrate the laundry in the washing tub 110 by centrifugal force. In the drying operation, while the drive unit 120 rotates the washing tub 110, for example, air heated by a heat pump or a heater provided in the washing machine main body 10 is blown into the washing tub 110 to blow the laundry in the washing tub 110. dry.

The acceleration sensor 131 measures the acceleration of the washing tub 110. The acceleration sensor 131 is used to detect the vibration of the washing tub 110 due to the deviation of the laundry in the washing tub 110.
The weight sensor 132 measures the weight of the washing tub 110 in a state where the laundry is housed. The weight measured by the weight sensor 132 is used as an index value of the amount of laundry in the washing tub 110. As the measured value by the weight sensor 132, the measured value after the laundry is put into the washing tub 110 and before the water is injected into the washing tub 110 may be used. For example, at the timing when a user operation instructing the start of washing by the washing machine main body 10 is performed, such as when the washing start button is pressed, the state information acquisition unit 311 acquires the measured value of the weight sensor 132 and stores the storage unit 320. You may memorize it in.

The cloth quality determination unit 133 determines the cloth quality of the laundry in the washing tub 110, for example, based on the detection result of the current detection unit that detects the current flowing through the drive unit 120 (so-called motor load current). The current detection unit may measure the motor load current when the stirrer at the bottom of the washing tub 110 is rotated before the start of water supply for the washing operation as the motor load current for determining the cloth quality, or the washing unit may measure the motor load current. The motor load current when the washing tub 110 is rotated during operation may be measured. Based on this measurement, the ratio of cotton to chemical fibers in the laundry can be estimated. The operation of the washing machine main body 10 in this case corresponds to an example of the cloth quality determination operation. However, the cloth chamber determination operation is not limited to the above example, and may be a different operation.
The acceleration sensor 131, the weight sensor 132, the cloth quality determination unit 133 (or the current detection unit), or a combination thereof corresponds to an example of a sensor mounted on the washing machine main body 10.

The washing control unit 140 controls each part of the washing machine main body 10 according to the operation course selected by the user, and causes a washing operation, a rinsing operation, a dehydration operation and a drying operation, or a part thereof. For example, the washing control unit 140 controls each unit of the washing machine main body 10 based on the control information stored in the storage unit 320 of the learning device 30. The control information referred to here is information indicating the operation method (setting content of the operation course) of the washing machine main body 10. For example, the control information indicates a method in which the washing control unit 140 controls each part of the washing machine main body 10, such as the rotation speed (rotation speed), rotation time, and various thresholds of the washing tub 110 in dehydration for each operation course. The control information includes, for example, the amount of water supplied in the washing operation, the amount of the washing treatment agent added by the automatic loading machine, the number of times the rinsing operation and the dehydration operation are performed multiple times in one washing, and the drying operation. It may include the heating amount of the heat pump in the above, the rotation speed of the fan that sends the drying air, the length of the drying time, and the like.

The control information stored in the storage unit 320 includes the user's evaluation of the operation of the washing machine main body 10 (for example, the user's evaluation of the finish of the laundry and / or the user's evaluation of the operation of the washing machine main body 10 itself). Is reflected. The washing control unit 140 controls each part of the washing machine main body 10 based on the control information, so that the user's evaluation of the operation of the washing machine main body 10 is reflected in the next and subsequent operations.
The washing control unit 140 changes the operation content of the washing machine main body 10 based on the result of the cloth quality determination operation (determination result by the cloth quality determination unit 133). For example, as a result of the cloth quality determination operation, the washing control unit 140 prolongs the drying time when the laundry has a large amount of cotton, as compared with the case where the laundry has a large amount of chemical fibers, and / or the temperature of the air blown during the drying operation. To raise.

The operation panel 20 functions as a user interface in the washing system 1. As described above, the operation panel 20 may be configured integrally with the washing machine main body 10, or may be configured as a device different from the washing machine main body 10.
The display unit 210 has a display screen such as a liquid crystal panel and displays various images. The input unit 220 includes, for example, an input device such as a touch sensor provided on the display screen of the display unit 210 and constitutes a touch panel, and accepts user operations.
For example, when the washing machine main body 10 operates, the display unit 210 displays the operation course selection screen, and the input unit 220 accepts the operation of selecting the operation course by the user. Further, the display unit 210 displays a question screen inquiring about the user's evaluation of the operation of the washing machine main body 10, and the input unit 220 accepts the user's evaluation input operation (user's answer to the question).

The learning device 30 updates the control information so that the user's evaluation received by the input unit 220 is reflected in the next and subsequent operations of the washing machine main body 10.
The state information acquisition unit 311 acquires state information from the washing machine main body 10. The state information referred to here is information indicating the operating state of the washing machine main body 10. For example, the state information indicates an operation course when the washing machine main body 10 operates, and measurement values or determination results of the acceleration sensor 131, the weight sensor 132, and the cloth quality determination unit 133, respectively.

The state determination unit 312 determines whether or not the state of the washing machine main body 10 satisfies a predetermined condition. An example in which a predetermined condition is satisfied is, for example, a state in which a state different from normal is detected. For example, the state determination unit 312 determines whether or not the laundry in the washing tub 110 is offset (whether or not the rotation of the washing tub 110 is unbalanced) based on the measured value of the acceleration by the acceleration sensor 131. The determination result by the state determination unit 312 is used, for example, as an opportunity for the display unit 210 to display the above question screen.

The evaluation information acquisition unit 313 acquires the evaluation information. The evaluation information is information indicating the user's evaluation of the operation of the washing machine main body 10. For example, the evaluation information is input by the user using the input unit 220, and the user's evaluation of the operation of the washing machine main body 10 (for example, the user's evaluation of the finish of the laundry and / or the operation of the washing machine main body 10). User's evaluation of itself) is shown.

The evaluation information acquisition unit 313 outputs a question inquiring about the user's evaluation of the operation of the washing machine main body 10, and receives the user's answer to acquire the evaluation information. The evaluation information acquisition unit 313 may output the question by displaying the question screen on the display unit 210. Then, the evaluation information acquisition unit 313 may acquire the evaluation information by receiving the user's answer to the question displayed by the display unit 210 via the input unit 220.

The learning unit 314 learns about the operation of the washing machine main body 10 based on the evaluation information acquired by the evaluation information acquisition unit 313. Specifically, the learning unit 314 updates the control information so that the user's evaluation of the operation of the washing machine main body 10 is reflected in the next and subsequent operations of the washing machine main body 10. For example, the learning unit 314 changes various operation parameters, threshold values, or operation times included in the control information in a direction of enhancing the user's evaluation by a preset predetermined change amount based on the user's evaluation. Then, in the next and subsequent operations of the washing machine main body 10 using the changed control information, the user's evaluation is acquired again, and the control information is changed in the direction of increasing the user's evaluation. By repeating such processing, the learning unit 314 optimizes the control information according to the user's preference.

The clothes type estimation unit 315 estimates the types of clothes and their proportions in the laundry in the washing tub 110. For example, the clothing type estimation unit 315 is based on the weight of the laundry measured by the weight sensor 132 and the cloth quality of the laundry (for example, the ratio of cotton and chemical fibers) determined by the cloth quality determination unit 133 (that is,). Estimate the type of garment and its proportion (based on the combination of weight and fabric). The estimation of the type of clothing is not essential to estimate the detailed type, but may be a simple estimation such as whether or not a specific clothing (for example, heavy clothing (sweater, bathrobe, etc.) is included). Further, the clothes type estimation unit 315 may determine whether or not a heavy laundry object (bath towel, bath mat, etc.) is included in the laundry in addition to the clothes. Therefore, "clothing" as used herein may be read as "laundry" or "laundry object".

The storage unit 320 stores various information. For example, the storage unit 320 stores driving course information, state information, evaluation information, and control information.
The driving course information is information indicating a driving course designated by the user among the driving courses preset for the operation of the washing machine main body 10. As described above, the state information is information indicating the state of the washing machine main body 10. As described above, the evaluation information is information indicating the user's evaluation of the operation of the washing machine main body 10. As described above, the control information is information indicating the operation method of the washing machine main body 10.

The learning device 30 may be configured by using a computer such as a microcomputer. The functions of the state information acquisition unit 311, the state determination unit 312, the evaluation information acquisition unit 313, the learning unit 314, and the clothing type estimation unit 315 are such that one or more hardware processors such as a CPU execute a program (software). It may be executed by doing. Alternatively, all or part of these functional parts may be realized by a circuit part (hardware) such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). , May be realized by the collaboration of software and hardware. The storage unit 320 is realized by a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk Drive), a flash memory, or a combination of a plurality of these.

FIG. 2 is a diagram showing a first example of the question screen. FIG. 2 shows an example of a question screen when inquiring a user's evaluation of the result of dehydration by the washing machine main body 10.
The display unit 210 shows the options of "1. I want to make the dehydration stronger", "2. Appropriate", and "3. I want to make the dehydration weaker" on the question screen illustrated in FIG. The answer to the question is performed, for example, by the user selecting one of the options on the question screen by touch operation and confirming the answer by touch operation to "answer completed". When the user selects one of the options, the learning unit 314 updates the setting of the dehydration strength in the control information according to the user's answer. Questions regarding the results of dehydration may be more intuitive to the user, such as "1. Still damp", "2. Appropriate", and "3. Clothes are wrinkled".

When the dehydration is strengthened, the learning unit 314 may update the control information so that the dehydration time becomes longer, or the control information may be updated so that the rotation speed of the washing tub 110 at the time of dehydration becomes faster. You may try to update. Alternatively, the learning unit 314 may update the control information so that the dehydration time becomes long and the rotation speed of the washing tub 110 during dehydration becomes high.

When the dehydration is weakened, the learning unit 314 may update the control information so that the dehydration time is shortened, or the control information may be updated so that the rotation speed of the washing tub 110 at the time of dehydration becomes slow. You may try to update. Alternatively, the learning unit 314 may update the control information so that the dehydration time is shortened and the rotation speed of the washing tub 110 during dehydration is slowed down.
In this way, the learning unit 314 updates the control information according to the user's answer, so that the user's evaluation of the operation of the washing machine main body 10 can be reflected in the operation of the washing machine main body 10 from the next time onward.

As described above, the determination result by the state determination unit 312 may be used as an opportunity for the display unit 210 to display the question screen (that is, an opportunity for the evaluation information acquisition unit 313 to ask a question to the user). For example, the vibration of the washing tub 110 is larger than a predetermined condition based on the measured value of the acceleration sensor 131, such as whether or not the magnitude of the acceleration measured by the acceleration sensor 131 exceeds a predetermined threshold value by the state determination unit 312. Whether or not (for example, whether or not the rotation of the washing tub 110 has an imbalance exceeding the threshold value) may be determined. Then, when the state determination unit 312 determines that the vibration of the washing tub 110 is larger than a predetermined condition (for example, when the rotation of the washing tub 110 has an imbalance exceeding the threshold value), the operation of the washing machine main body 10 is terminated. Occasionally, the evaluation information acquisition unit 313 may display the question screen on the display unit 210 to acquire the user's answer. Further, every time the evaluation information acquisition unit 313 acquires the user's answer, the learning unit 314 may update the control information based on the user's answer.

In this way, by determining whether or not the evaluation information acquisition unit 313 outputs a question to the user according to the determination result of the state determination unit 312, the frequency of the question to the user and the frequency of updating the control information can be determined. It can be limited, and in this respect, the load on the learning device 30 can be reduced.
Further, when the state determination unit 312 determines that the vibration of the washing tub 110 is larger than a predetermined condition, the evaluation information acquisition unit 313 outputs a question to the user, for example, to prioritize the reduction of the vibration. Alternatively, the user's instruction as to whether to prioritize the degree of dehydration can be reflected in the control information.

Alternatively, the evaluation information acquisition unit 313 may ask a question to the user at the opportunity based on the operating time of the washing machine main body 10. For example, the state information may include information indicating the operating time of the washing machine main body 10. Then, when the operation time of the washing machine main body 10 becomes longer than the scheduled time calculated in advance, the state determination unit 312 may determine that the operating state of the washing machine main body 10 satisfies a predetermined condition. Also in this case, when the state determination unit 312 determines that the operating state of the washing machine main body 10 satisfies the predetermined condition, the evaluation information acquisition unit 313 displays a question screen on the display unit 210 at the end of the operation of the washing machine main body 10. It may be displayed and the user's answer may be obtained. Further, every time the evaluation information acquisition unit 313 acquires the user's answer, the learning unit 314 may update the control information based on the user's answer.

In this way, by determining whether or not the evaluation information acquisition unit 313 outputs a question to the user according to the determination result of the state determination unit 312, the frequency of the question to the user and the frequency of updating the control information can be determined. It can be limited, and in this respect, the load on the learning device 30 can be reduced.
Here, for example, in the case of dehydration, as an example of the case where the operating time of the washing machine main body 10 is longer than the scheduled time, the washing machine main body 10 dehydrates when the laundry is biased in the washing tub 110. There is a case to start over. If the offset of the laundry is not resolved in the washing tub 110 during dehydration (when an offset error occurs), for example, the washing control unit 140 stops dehydration and supplies water to the washing tub 110 again to supply water to the washing tub 110. You may try to eliminate the unevenness of the laundry by stirring the water and the laundry by rotating the laundry and loosening the laundry. After that, the washing control unit 140 may control the driving unit 120 to rotate the washing tub 110 to cause dehydration again.

When the state determination unit 312 determines that the dehydration time is longer than the scheduled time, the evaluation information acquisition unit 313 outputs a question to the user, so that, for example, the operation time of the washing machine main body 10 (for example, washing ends earlier). It is possible to reflect the user's preference such as whether to prioritize the degree of dehydration or the degree of dehydration in the control information. For example, when the operation time of the washing machine main body 10 is prioritized, the learning unit 314 updates the control information so as to raise the threshold value for determining the offset error for stopping the dehydration and restarting the water supply.

Further, for example, in the case of drying, as an example of the case where the operating time of the washing machine main body 10 is longer than the scheduled time, there are many materials (for example, cotton) that easily contain water in the laundry, and the laundry does not dry and the drying time does not proceed. May be longer than the scheduled time.
When the state determination unit 312 determines that the drying time is longer than the scheduled time, the evaluation information acquisition unit 313 outputs a question to the user, so that, for example, the operating time of the washing machine main body 10 (for example, drying ends earlier). It is possible to reflect the user's preference, such as whether to prioritize the dryness or the dryness, in the control information. For example, when the learning unit 314 gives priority to the operation time of the washing machine main body 10, the learning unit 314 states that "a large amount of cotton is contained" as a result of the cloth quality determination operation (for example, the result of processing by the clothing type estimation unit 315). The threshold value for judgment included in the control information is changed so that the judgment can be made easily.

Alternatively, the evaluation information acquisition unit 313 may ask a question to the user each time the washing machine main body 10 finishes washing.
Further, the trigger and frequency of asking a question may be different for each question asked by the evaluation information acquisition unit 313 to the user.

The learning unit 314 may perform learning based on the correspondence between the state information and the evaluation information. For example, the learning unit 314 controls the measured value of the weight by the weight sensor 132 in the operation in which the evaluation information is obtained in association with the rotation speed and the dehydration time of the washing tub 110 at the time of dehydration determined based on the evaluation information. You may register it in the information. As described above, the measured value of the weight by the weight sensor 132 is used as an index value of the weight of the laundry in the washing tub 110.

Then, during the next and subsequent operations, the washing control unit 140 determines the rotation speed of the washing tub 110 during dehydration based on the difference between the weight measured by the weight sensor 132 and the weight registered in the control information. Alternatively, either or both of the dehydration times may be corrected and used.
Alternatively, the learning unit 314 may learn the rotation speed and the dehydration time of the washing tub 110 at the time of dehydration for each measured value of the weight by the weight sensor 132.

Further, when the user's evaluation of the degree of dehydration of the laundry is low and the magnitude of the vibration of the washing tub 110 according to the measured value of the acceleration sensor 131 is equal to or less than a predetermined threshold value, the learning unit 314 performs the washing tub at the time of dehydration. Learning may be performed so as to increase the rotation speed of 110. On the other hand, when the user's evaluation of the degree of dehydration of the laundry is low and the magnitude of vibration of the washing tub 110 is larger than a predetermined threshold value, the learning unit 314 performs learning so that the dehydration time becomes longer. You may.

The learning unit 314 may learn the rotation speed of the washing tub 110 at the time of dehydration for each weight of the laundry. For example, when the laundry is light, the rotation speed of the washing tub 110 tends to increase. Therefore, the learning unit 314 may shorten the dehydration time by updating the control information so that the rotation speed of the washing tub 110 becomes faster when the laundry is light.

By storing the question from the evaluation information acquisition unit 313 in the operation panel 20, the user may be able to answer the question at any time, not only at the end of the operation of the washing machine main body 10. For example, as described above, the operation panel 20 may be configured by using a smartphone, a personal computer, or a tablet terminal device. Then, the learning unit 314 may send a question to the operation panel 20 by e-mail, and the operation panel 20 may save this mail. Then, the operation panel 20 may generate an answer mail to the question according to the user operation and send it to the learning unit 314.

FIG. 3 is a diagram showing a second example of the question screen. FIG. 3 shows an example of a question screen when inquiring a user's rating that does not distinguish between ratings for washing, rinsing, dehydration, or drying. An evaluation that does not distinguish between evaluations related to washing, rinsing, dehydration, or drying is also referred to as a comprehensive evaluation.
The display unit 210 is a question screen exemplified in FIG. 3, in which "A. Degree of dirt removal", "B. Degree of softener", "C. Dehydration / drying degree", and "D. Required". The question item of "time" is shown. For the user's answer to each question item, for example, the user selects one of 1 to 5 points for each item on the question screen by touch operation, and confirms the answer by touch operation to "answer completed". It is done in.

All of "A. Deterioration of dirt", "B. Dehydration / drying degree", and "D. Time required" in FIG. 3 are washed, rinsed, dehydrated, or dried. It is not specified whether the evaluation is related to any of the above. In addition, "A. degree of stain removal", "B. degree of softener attachment" and "C. degree of dehydration / drying" can be said to be evaluation items regarding the finish condition of the laundry, respectively. On the other hand, "D. Required time" can be said to be an evaluation item relating to the operation itself of the washing machine main body 10. As described above, the question about the user's comprehensive evaluation performed by the evaluation information acquisition unit 313 includes the question about the comprehensive evaluation for the finish of the laundry and the question about the comprehensive evaluation for the operation itself of the washing machine main body 10. Any or both of these may be included. Instead of these, the question about the comprehensive evaluation may be a question such as "1. I am satisfied with this driving" and "2. I am dissatisfied with this driving".

The learning unit 314 learns an individual operation such as a washing operation, a rinsing operation, a dehydration operation, or a drying operation of the washing machine main body 10 based on the correspondence between the state information and the evaluation information indicating the user's comprehensive evaluation. You may do so.
For example, the storage unit 320 stores in advance the correspondence between the items of the comprehensive evaluation and each operation of the washing machine main body 10, and the learning unit 314 learns the individual operation based on this correspondence. May be good.

Further, for example, the storage unit 320 may store information that "A. How much dirt is removed" is an item related to the washing operation. Then, the learning unit 314 may learn the washing operation based on the user's evaluation (the score of the answer) for "A. How the dirt is removed". In the learning of the washing operation, the learning unit 314 updates the washing operation information among the control information.

For example, when the user's evaluation of "A. How much dirt is removed" is low, the learning unit 314 has a strong water flow in the washing operation, a large amount of water, or both. The control information may be updated. As a method of increasing the strength of the water flow, in the case of a drum-type washing machine, the rotation speed or acceleration of the washing tub 110 (drum), or both of them may be increased. Alternatively, in the case of a vertical washing machine, in addition to or instead of increasing the rotation speed or acceleration of the washing tub 110 (rotary tub), or both, the operation of the stirrer (pulsator) is increased. You may try to do it.

Further, the storage unit 320 may store information that "B. Condition of softener" is an item related to the rinsing operation. Then, the learning unit 314 may learn the rinsing operation based on the user's evaluation of "B. Condition of softener". In the learning of the rinsing operation, the learning unit 314 updates the rinsing operation information among the control information.

For example, when the user's evaluation of "B. Softener adhesion" is low, the learning unit 314 increases the rotation speed of the washing tub 110 in the rinsing operation, increases the number of rinsings, or injects water during rinsing. The control information may be updated so that the control information is used or a combination of these is performed.
Alternatively, the evaluation information acquisition unit 313 may acquire the user's evaluation for the degree of removal of the detergent in addition to or instead of the degree of attachment of the softener. Then, the learning unit 314 may learn the rinsing operation based on the user's evaluation of the degree of detergent removal in addition to or instead of the degree of attachment of the softener.

Further, the storage unit 320 may store information that "C. Dehydration / drying degree" is an item related to the dehydration operation and the drying operation. Then, the learning unit 314 may perform the dehydration operation, the drying operation, or both of them based on the user's evaluation of "C. Dehydration / drying degree". In the learning of the dehydration operation, the learning unit 314 updates the information of the dehydration operation among the control information. In the learning of the drying operation, the learning unit 314 updates the information of the drying operation among the control information.

For example, when the user's evaluation of "C. Degree of dehydration / drying" is low, the learning unit 314 determines that the rotation speed of the washing tub 110 in the dehydration operation becomes faster, the rotation time becomes longer, or both of them. The control information may be updated as it is done.
Further, when the user's evaluation of "C. Dehydration / drying degree" is low, the learning unit 314 has a high air temperature, a large air volume, or an air time (drying time) in the washing tub 110. The control information may be updated so that the time becomes longer or a combination of these is performed. As a method of increasing the blowing temperature, the heating amount of a heat pump or a heater for heating the blown air may be increased. As a method of increasing the amount of air blown, the rotation speed of the fan that blows air may be increased.

Further, the storage unit 320 may store information that the "D. required time" is an item related to a washing operation, a rinsing operation, a dehydrating operation, and a drying operation. Then, the learning unit 314 may perform learning of washing operation, rinsing operation, dehydration operation or drying operation, or a combination thereof, based on the user's evaluation of "D. Required time".
For example, when the user's evaluation of "D. Required time" is low, the learning unit 314 has a shorter washing time, a shorter rinsing time, a shorter number of rinses, a shorter dehydration time, or a shorter drying time. The control information may be updated so that it is shortened or a combination of these is performed.

Further, the learning unit 314 may update the control information as described above with respect to the operation of shortening the time in order to maintain the quality of the finished condition of the laundry. For example, when the learning unit 314 shortens the washing time, the control information may be updated so that the strength of the water flow in the washing operation becomes stronger, the amount of water becomes larger, or both are performed. good.

Even when the evaluation information acquisition unit 313 acquires the comprehensive evaluation, the learning unit 314 may perform learning based on the correspondence between the state information and the evaluation information. In this case as well, the learning unit 314 may perform learning of each movement based on the correspondence between the state information and the evaluation information, as described above for the example in the case of the dehydration movement.

Alternatively, the learning unit 314 may, in addition to or instead of learning the individual movements, learn the comprehensive learning related to a plurality of movements based on the correspondence between the state information and the evaluation information. good.
For example, when the user's evaluation of "C. Degree of dehydration / drying" is low and the magnitude of vibration of the washing tub 110 according to the measured value of the acceleration sensor 131 is equal to or less than a predetermined threshold value, the learning unit 314 dehydrates. Learning may be performed so as to increase the rotation speed of the washing tub 110 at the time. On the other hand, when the user's evaluation of "C. Degree of dehydration / drying" is low and the magnitude of vibration of the washing tub 110 is larger than a predetermined threshold value, the learning unit 314 blows air temperature into the washing tub 110. May be increased, the amount of air blown may be increased, the air blown time (drying time) may be lengthened, or learning may be performed so that a combination thereof is executed.

FIG. 4 is a diagram showing a third example of the question screen. FIG. 4 shows an example of a question screen when inquiring a user's evaluation of the vibration of the washing tub during dehydration.
The display unit 210 shows the options of "1. It is okay as it is" and "2. I want to reduce the vibration more" with respect to the vibration of the washing tub at the time of dehydration on the question screen illustrated in FIG. The answer by the user is performed, for example, by the user selecting one of the options by touch operation on the question screen and confirming the answer by touch operation to "answer completed".

The evaluation information acquisition unit 313 obtains evaluation information indicating the user's evaluation of the magnitude of vibration during the dehydration operation of the washing machine main body 10 (particularly the washing tub 110) by the user's answer to the question screen exemplified in FIG. get. The learning unit 314 learns about the dehydration operation of the washing machine main body 10 based on the correspondence between the state information and the evaluation information.

For example, consider a case where vibration due to the deviation of the laundry in the washing tub 110 is temporarily detected based on the measured value of the acceleration sensor 131. The vibration caused by the deviation of the laundry in the washing tub 110 here means that the deviation of the center of gravity occurs due to the deviation of the laundry in the washing tub 110, and the washing tub 110 is the other in the washing machine main body 10. It hits the part and causes vibration.

The vibration caused by the deviation of the laundry in the washing tub 110 is determined, for example, that the magnitude of the acceleration measured by the acceleration sensor 131 becomes larger than a predetermined threshold at a frequency of a predetermined number of times or more within a predetermined time. Detected by criteria.
The vibration caused by the deviation of the laundry in the washing tub 110 may be eliminated by moving the laundry according to the rotation of the washing tub 110, for example. In this case, vibration due to the deviation of the laundry in the washing tub 110 is temporarily detected.

When the user's answer on the question screen of FIG. 4 is "1. It is okay as it is", the learning unit 314 does not change the content of the control information. In particular, the learning unit 314 uses the rotation speed of the washing tub 110 at the time of dehydration as it is in the control information. It can be said that this means that maintaining the degree of dehydration is prioritized over suppressing vibration due to the bias of the laundry in the washing tub 110.

On the other hand, when the user's answer on the question screen of FIG. 4 is "2. I want to reduce the vibration more", the learning unit 314 provides control information so that the rotation speed of the washing tub 110 at the time of dehydration becomes slow. Update. In the next and subsequent operations, the rotation speed of the washing tub 110 during dehydration slows down, which reduces the possibility of vibration due to the deviation of the laundry in the washing tub 110, or washing in the washing tub 110. It is expected that the magnitude of vibration due to the deviation of objects will be smaller. Further, the learning unit 314 may update the control information so that the dehydration time becomes long. This is expected to maintain the degree of dehydration.

The evaluation information acquisition unit 313 asks the user's evaluation of the loudness of the sound during dehydration in addition to or instead of the question of the user's evaluation of the magnitude of the vibration during dehydration exemplified in FIG. You may.

FIG. 5 is a diagram showing a fourth example of the question screen. FIG. 5 shows an example of a question screen when inquiring a user's evaluation of floor vibration during dehydration.
The display unit 210 shows the options of "1. It is okay as it is" and "2. I want to reduce the vibration more" for the vibration of the floor during dehydration on the question screen illustrated in FIG. The answer by the user is performed, for example, by the user selecting one of the options by touch operation on the question screen and confirming the answer by touch operation to "answer completed".

The evaluation information acquisition unit 313 responds to the user's answer to the question screen exemplified in FIG. 5 by the user's response to the magnitude of vibration of the floor on which the washing machine main body 10 is installed during the dehydration operation of the washing machine main body 10. Acquire evaluation information indicating evaluation. The learning unit 314 learns about the dehydration operation of the washing machine body based on the correspondence between the state information and the evaluation information.

The magnitude of the vibration of the washing tub 110 mainly affects the sound in the space where the washing machine main body 10 is installed, whereas the vibration of the floor is the washing machine main body 10 such as in another room or another floor. There is a high possibility that it will be felt in spaces other than the space where the is installed. In this respect, the vibration of the floor may be more influential than the vibration of the washing tub 110.

Further, it is considered that the vibration of the floor has a larger individual difference in the way of feeling than the sound caused by the vibration of the washing tub 110. Further, it is considered that an acceleration sensor or the like is not installed on the floor, and in this respect, it can be said that the user's evaluation of the vibration of the floor cannot be replaced by the sensor measured value.
The evaluation information acquisition unit 313 acquires the user's evaluation for the floor vibration as in the example of FIG. 5, and the learning unit 314 determines the necessity of countermeasures against the floor vibration and takes countermeasures as necessary. You can learn.

When the user replies that he / she wants to reduce the vibration of the floor, the learning unit 314 updates the control information so that the rotation speed of the washing tub 110 at the time of dehydration becomes slow. When the rotation speed of the washing tub 110 is set to change during dehydration, the learning unit 314 may update the control information so that the maximum rotation speed becomes slower.

Here, if the user is out, it is considered that he / she does not know the vibration of the floor. Therefore, when the operation panel 20 is configured to be portable and the evaluation information acquisition unit 313 can acquire the position information of the operation panel 20, the evaluation information acquisition unit 313 and the operation panel 20 are installed with the washing machine main body 10. It may be determined whether or not it is located indoors. Then, when it is determined that the operation panel 20 is located outdoors (not located indoors), the evaluation information acquisition unit 313 may not ask a question regarding the vibration of the floor.
The same applies to the magnitude of vibration of the washing tub 110.

FIG. 6 is a diagram showing a fifth example of the question screen. FIG. 6 shows an example of a question screen when inquiring about the type of clothes contained in the laundry.
The display unit 210 is a question screen exemplified in FIG. 6, regarding the types of clothes contained in the laundry, "1. outerwear", "2. T-shirts", "3. underwear", "4. The choices of ". Socks" and "5. Towels, bath towels" are shown. The answer by the user is performed, for example, by the user selecting all the clothes included in the laundry by touch operation on the question screen and confirming the answer by touch operation to "answer completed".

Here, it is conceivable to change the washing method according to the weight of the laundry and the type of clothes. For example, it is conceivable that the tendency of the laundry to be biased differs depending on the type and amount of the laundry, and the necessity or degree of measures against vibration during dehydration may differ. Alternatively, it is conceivable to change the settings of various operations of the washing machine main body 10, such as the amount of detergent at the time of washing, not limited to the measures against the vibration at the time of dehydration, according to the weight of the laundry and the type of clothes. Therefore, the learning unit 314 may update the control information so that the weight of the laundry and the type of the clothes are reflected in the operation of the washing machine main body 10.

For example, the evaluation information acquisition unit 313 displays a question screen for inquiring about the clothing type exemplified in FIG. 6 on the display unit 210, acquires the answer of the clothing type, and causes the learning unit 314 as clothing type information. Output. The clothing type information referred to here is information indicating the type of clothing contained in the laundry. The evaluation information acquisition unit 313 may also acquire the user's evaluation of the operation of the washing machine main body 10 and output the evaluation information and the clothes type information to the learning unit 314 in association with each other.

The learning unit 314 learns about the operation of the washing machine main body 10 according to the type of clothes based on the clothes type information from the evaluation information acquisition unit 313. For example, the learning unit 314 controls an equation for calculating the control amount of the water flow strength at the time of washing or rinsing according to the value of the clothes type information and the measured value (weight of the laundry) of the weight sensor 132. It may be included in the information.
The strength of the water flow here corresponds to an example of measures against vibration during dehydration due to the bias of the laundry. By increasing the water flow and stirring the laundry well, it is expected that the unbalance of the laundry will be eliminated even if there are many types of clothes such as cotton that tend to be unbalanced. As the control amount of the water flow strength, for example, the magnitude of the current of the motor constituting the drive unit 120 when the drive unit 120 repeatedly rotates and stops the washing tub 110 can be used.

When the evaluation information and the clothes type information are linked, the learning unit 314 learns about the operation of the washing machine main body 10 according to the clothes type based on the clothes type information and the evaluation information. For example, the learning unit 314 reflects the weight of the laundry and the type of clothes on the strength of the water flow, and also reflects the user's evaluation of the operation of the washing machine main body 10 indicated by the evaluation information in the control information. The operation of the washing machine main body 10 can be reflected in the control information of the user's evaluation by, for example, the method described with reference to FIGS. 2 to 5.

It is a burden for the user to answer the type of clothes for each wash. Therefore, the clothes type estimation unit 315 is included in the laundry based on the weight of the laundry measured by the weight sensor 132 and the cloth quality of the laundry (cloth quality of the clothes) determined by the cloth quality determination unit 133. Estimates the type of clothing to be used and generates clothing type information.
For example, when the user's answer about the type of clothing is obtained, the cloth quality determination unit 133 associates the user's answer with the measured value of the weight sensor 132 and the determination result of the cloth quality determination unit 133. , May be stored in the storage unit 320. Then, among the user's answers stored in the storage unit 320, the clothes type estimation unit 315 answers that the measured value of the weight sensor 132 and the determination result of the cloth quality determination unit 133 are the closest to the measured values in this washing. May be acquired and used as clothing type information.

The washing control unit 140 of the washing machine main body 10 controls the washing machine main body 10 based on the type of clothes estimated by the clothes type estimation unit 315 and the contents learned by the learning unit 314. For example, the washing control unit 140 inputs the measured value of the weight sensor 132 and the clothing type information as the estimation result of the clothing type estimation unit 315 into the above formula set by the learning unit 314 to determine the strength of the water flow. The control amount is calculated, and the drive unit 120 is controlled based on the calculated control amount. As described above, the learning unit 314 may calculate the magnitude of the current of the motor constituting the drive unit 120 as the control amount of the strength of the water flow.

The evaluation information acquisition unit 313 may accept the user's reply including the clothes type information when an error (misalignment error) caused by the deviation of clothes occurs during the operation of the washing machine main body 10. As an example of the error caused by the deviation of clothes, there is a vibration error at the time of dehydration, such that the magnitude of the vibration of the washing machine main body 10 by the acceleration sensor 131 becomes larger than a predetermined threshold value at the time of dehydration. When the washing machine main body 10 is stopped due to such a vibration error during dehydration, the evaluation information acquisition unit 313 inquires the user about the type of clothes via the operation panel 20 and acquires the clothes type information as an answer. You may do it.

In this case, it can be said that the clothing type information based on the user's response is information indicating the type of clothing in the case where measures against the deviation of the clothing are required. Therefore, the learning unit 314 controls so that when the same weight of laundry and the type of clothes as when the clothes type information is obtained from the user's answer is detected, measures against the deviation of the clothes are taken. The information may be updated.

For example, when the clothing type information based on the user's answer is obtained, the learning unit 314 links the clothing type information, the weight measurement value by the weight sensor 132, and the countermeasure against the deviation of the clothing. , May be included in the control information. Then, the washing control unit 140 acquires the measured value of the weight by the weight sensor 132 and the clothes type information by the clothes type estimation unit 315 at the start of washing by the washing machine main body 10, and it is necessary to take measures against the deviation of clothes. You may decide whether or not.

For example, the washing control unit 140 determines whether or not the control information includes the obtained clothes type information and the clothes type and weight information having the same contents as the weight measurement value. When the particle size of the weight measured by the weight sensor 132 is fine, the washing control unit 140 may determine whether or not the weight information within a predetermined range is included around the weight measurement value. When it is determined that the information on the type and weight of the corresponding clothes is included, the washing control unit 140 reads out the measures against the deviation of the clothes associated with the information from the control information and executes the measures.

As a result, it is possible to reduce the possibility that the error will occur again when the combination of clothes is the same as when the error occurred in the operation after the error caused by the deviation of the clothes occurs.
Further, the burden on the user is relatively light in that the user only needs to answer the type of clothing when an error caused by the deviation of the clothing occurs.

When the evaluation information acquisition unit 313 asks a question to the user when an error has occurred and when an error has not occurred, the learning unit 314 gives priority to the user's answer when the error has occurred. It may be reflected in the control information.

The learning unit 314 may learn the operation of the washing machine main body 10 for each time zone, each day of the week, each season, and other time factors. Alternatively, the learning unit 314 may learn the operation of the washing machine main body 10 according to the factors of the installation environment of the washing machine main body 10 such as each maximum temperature or instead of the time factor.

Regarding the time zone, the user's evaluation regarding the operation of the washing machine main body 10 may differ depending on the time zone. For example, it is possible that the user is more likely to be concerned about vibration and sound at night than during the day.
The learning unit 314 learns the operation of the washing machine main body 10 for each time zone, so that the washing control unit 140 considers the time zone when determining the control method of the washing machine main body 10 based on the control information. The control method can be determined with high accuracy. According to the washing system 1, in this respect, the user's evaluation can be reflected with high accuracy in the operation of the washing machine main body 10.

Regarding the day of the week, for example, work clothes are often washed on weekdays, but everyday clothes are often washed on holidays, and the types of clothes included in the laundry may differ depending on the day of the week. In addition, the amount of laundry may differ depending on the day of the week, such as more laundry on holidays than on weekdays.
The learning unit 314 learns the operation of the washing machine main body 10 for each day of the week, and the washing control unit 140 controls in consideration of the day of the week when determining the control method of the washing machine main body 10 based on the control information. The method can be determined with high accuracy. According to the washing system 1, the operation of the washing machine main body 10 can be controlled with high accuracy in this respect.

Regarding the seasons, the types of clothes contained in the laundry may differ depending on the season, for example, T-shirts are washed relatively often in summer and sweaters are washed relatively often in winter. In addition, the amount of laundry may vary depending on the season, such as the amount of laundry being heavier in winter than in summer. Further, it is conceivable that the vibration method of the washing tub 110 differs depending on the temperature, for example, the suspension supporting the washing tub 110 thermally expands depending on the season and the characteristics change.
The learning unit 314 learns the operation of the washing machine main body 10 for each season, and the washing control unit 140 controls in consideration of the season when determining the control method of the washing machine main body 10 based on the control information. The method can be determined with high accuracy. According to the washing system 1, the operation of the washing machine main body 10 can be controlled with high accuracy in this respect.

Regarding the maximum temperature, the type of clothes included in the laundry depends on the maximum temperature, such as the fact that T-shirts are washed relatively often on days when the maximum temperature is high, while sweaters are washed relatively often on days when the maximum temperature is low. It may be different. In addition, the amount of laundry may differ depending on the maximum temperature, for example, the amount of laundry is larger on days when the maximum temperature is low than on days when the maximum temperature is high. Further, it is conceivable that the vibration method of the washing tub 110 differs depending on the maximum temperature, for example, the suspension supporting the washing tub 110 thermally expands depending on the air temperature and the characteristics change.
The learning unit 314 learns the operation of the washing machine main body 10 for each season, and the washing control unit 140 controls in consideration of the season when determining the control method of the washing machine main body 10 based on the control information. The method can be determined with high accuracy. According to the washing system 1, the operation of the washing machine main body 10 can be controlled with high accuracy in this respect.

When the washing machine main body 10 automatically inputs the detergent, the evaluation information acquisition unit 313 inquires about the user's evaluation of the detergent usage amount, and the learning unit 314 learns the detergent usage amount according to the evaluation. good.
For example, when the washing machine main body 10 has used up a certain amount of detergent, the evaluation information acquisition unit 313 presents to the user the number of washings until the washing machine is used up, and the user decides whether or not to reduce the amount of detergent input. You may contact us. When there is a reply that the amount of detergent added is desired to be reduced, the learning unit 314 may update the control information so that the amount of detergent added in one washing is reduced. When there is a concern that stains remain on the laundry due to a decrease in the amount of detergent added, the learning unit 314 may update the control information so as to improve stain removal, for example, by setting a long washing time. ..

The learning unit 314 may learn the timing of prompting the user to take care of a filter such as a drying filter or a dehydration filter according to the evaluation of the user.
It is considered that the operating time of the washing machine main body 10 tends to be long when dust or the like is accumulated in the filter, so that the drying time becomes long when dust is accumulated in the drying filter. Therefore, the evaluation information acquisition unit 313 may inquire about the user's evaluation of the operating time of the washing machine main body 10. If the user wants the washing machine body 10 to have a short operating time, the learning unit 314 may update the control information so that the user is notified to take care of the filter at a relatively early stage. good. On the other hand, if the user does not care about the operating time of the washing machine main body 10, the learning unit 314 may update the control information so that the notification prompting the user to take care of the filter is given at a relatively late stage. .. In this case, the burden on the user is reduced in that the frequency of maintenance of the filter by the user is reduced.

The learning unit 314 may learn the amount of water used (water level at the time of washing or rinsing) according to the user's evaluation of the degree of stain removal of the laundry. This makes it possible to save water.
The learning unit 314 may learn the degree of stirring of the laundry by the pulsator or the like according to the user's evaluation of the degree of stain removal of the laundry or the user's evaluation of the degree of entanglement of the laundry. It is conceivable that when the degree of agitation of the laundry is increased, the dirt is easily removed, but the laundry is easily entangled. The learning unit 314 learns the degree of stirring of the rinse according to the user's evaluation, and reflects the user's evaluation in adjusting the trade-off between the degree of dirt removal of the laundry and the degree of entanglement of the laundry. Can be done.

FIG. 7 is a flowchart showing an example of a procedure of a process in which the learning device 30 learns the operation of the washing machine main body 10. FIG. 7 shows an example in which the learning device 30 is integrally configured with the washing machine main body 10. The learning device 30 starts the process of FIG. 7, for example, when the power switch of the washing machine main body 10 is turned on and the washing machine main body 10 and the learning device 30 are energized.

In the process of FIG. 7, the state determination unit 312 determines whether or not the question condition is satisfied (step S101). The question condition referred to here is a condition that serves as a criterion for determining whether or not to ask a question to the user. Question conditions are not limited to specific conditions. For example, when the learning device 30 asks a question to the user every time the operation of the washing machine main body 10 (washing by the washing machine main body 10) is completed, the operation of the washing machine main body 10 is completed and the operation of the washing machine main body 10 is completed as a question condition. You can use the condition that you haven't asked a question yet. Alternatively, when the learning device 30 asks a question to the user when the operation of the washing machine main body 10 is stopped due to an error, as a question condition, the operation of the washing machine main body 10 is stopped due to an error and the question is still asked. It is possible to use the condition that the above is not performed. Different question conditions may be set for each question.

When the state determination unit 312 determines that the question condition is not satisfied (step S101: NO), the process returns to step S101.
On the other hand, when the state determination unit 312 determines that the question condition is satisfied (step S101: YES), the evaluation information acquisition unit 313 causes the display unit 210 of the operation panel 20 to display the question screen (step S102). Then, the evaluation information acquisition unit 313 acquires an answer input by the user by a user operation using the input unit 220 (step S103).
Then, the washing control unit 140 updates the control information according to the user's answer (step S104).
After step S104, the process returns to step S101.

When the washing machine main body 10 and the learning device 30 are configured as separate devices such as when the learning device 30 is configured as a server device, for example, the washing machine main body 10 side such as the washing control unit 140 determines in step S101.

Then, when it is determined that the question condition is satisfied, the washing machine main body 10 may send a request to the learning device 30 to perform the process of step S102 or less.

FIG. 8 is a diagram showing an example of a processing procedure in which the washing machine main body 10 operates. The washing machine main body 10 starts the process of FIG. 8 at the start of washing, for example, when the washing start button is pressed.
In the process of FIG. 8, the washing control unit 140 acquires the driving course information and the state information (step S201). For example, when the user operation for selecting the driving course is performed, the washing control unit 140 acquires information indicating the driving course selected by the user operation as the driving course information. Further, the washing machine main body 10 acquires, for example, sensing data of sensors mounted on the washing machine main body 10 such as the weight sensor 132 and the cloth quality determination unit 133 as state information.

Next, the washing control unit 140 reads out the control method corresponding to the operation course and the state information from the control information stored in the storage unit 320 (step S202).
Then, the washing control unit 140 controls each part of the washing machine main body 10 based on the read control method to execute the operation of the washing machine main body 10 (step S203).
After step S203, the washing machine main body 10 ends the process of FIG.

As described above, the evaluation information acquisition unit 313 outputs (displays) a question inquiring about the user's evaluation of the operation of the washing machine main body 10 to the display unit 210, and receives the user's answer via the input unit 220. Acquires evaluation information indicating the user's evaluation of the operation of the washing machine main body 10. The learning unit 314 learns about the operation of the washing machine main body 10 based on the evaluation information.
As a result, in the washing system 1, the user's evaluation of washing can be reflected in the next and subsequent washings.

Here, it is considered that there are individual differences in how the washing machine main body 10 feels about the operation, such as whether or not the vibration and sound during the operation of the washing machine main body 10 are annoying. According to the washing system 1, by learning about the operation of the washing machine main body 10 based on the user's evaluation, the operation of the washing machine main body 10 reflects individual differences in how the washing machine main body 10 feels about the operation of the washing machine main body 10. Can be customized to the operation according to the user's request. At that time, the user may answer the user's own evaluation of the operation of the washing machine main body 10. For example, the operation of the washing machine main body 10 such as how many rotation speeds of the washing tub 110 at the time of dehydration are set per minute. There is no need to set. Therefore, the user can answer the question without requiring knowledge such as the influence of the operation of the washing machine main body 10 on the finish of the laundry and the surrounding environment.
