Description

  Embodiments described herein relate generally to a clothing processing apparatus.

  In a clothing processing apparatus such as a washing machine or a washing / drying machine, for example, when it is specified that an error has occurred during the washing operation, error information indicating the content of the error that has occurred is displayed on the main body, or the error information is displayed on the product. Or to a server managed by the manufacturer. There are two types of errors that occur: an error that can be resolved by the user, and an error that can only be resolved by a service person who is in charge of repair. Therefore, if an error that can only be resolved by a serviceman occurs, the device may not be usable until the serviceman responds, which inconveniences the user.

  Under such circumstances, for example, Patent Document 1 discloses a system that predicts the occurrence of an error and enables appropriate measures before the error occurs. In the configuration of Patent Document 1, when the clothing processing apparatus enters a predetermined state such as when the power is turned on, the operation is completed, or a predetermined date and time is reached, the device specific management information is transmitted to the server. When the server receives the device-specific management information transmitted from the clothing processing apparatus, the server collates the received device-specific management information with management information and treatment information stored in a database in advance, and predicts the occurrence of an error. And determine the actions to prevent the occurrence of errors.

JP 2007-282778 A

  However, in the configuration of Patent Document 1, since the server predicts the occurrence of an error, the clothing processing apparatus needs to transmit a large amount of data enough for the server to predict the occurrence of the error to the server. In addition, since the clothing processing apparatus transmits the device-specific management information to the server every time the power is turned on, the operation is completed, or every predetermined date and time, the device-specific management is performed even in a situation where the possibility of an error is extremely low. Information is sent to the server. As described above, in the clothing processing apparatus, a large amount of data is frequently transmitted, and there is a problem that the processing load for transmitting the device-specific management information increases.

  In view of this, the present embodiment provides a clothing processing apparatus that enables appropriate treatment before an error occurs while reducing the processing load for transmitting information to a server.

  The clothing processing apparatus of the present embodiment includes a water tank, a rotating tank provided in the water tank, a motor that rotates the rotating tank, and a detection unit that detects a physical quantity indicating an operation state of components related to operation of the device.

The numerous holes 5b function as water passage holes through which water passes during the washing process, the rinsing process, and the dehydration process, and function as ventilation holes through which the drying air passes during the drying process.

  A drum motor 7 (shown also in FIG. 2) made of, for example, an outer rotor type brushless motor is disposed at the rear of the water tank 3. The tip of the rotating shaft 7 a of the drum motor 7 penetrates the back surface of the water tank 3 and protrudes into the water tank 3, and is connected and fixed to the center of the rear part of the drum 5. With such a configuration, the drum 5 is directly rotated by the drum motor 7.

  The water tank 3 is provided with an upward air outlet 8 at the upper part of the front portion of the peripheral wall portion, and with a rearward air outlet 9 at the upper portion of the rear wall. A filter 11 is connected to the upper part of the air outlet 8 through a connection duct 10 that is formed in a bellows shape so as to absorb vibration. The filter 11 is configured such that a lint filter (not shown) is detachably attached in a box-shaped case constituting the main body. The filter 11 captures foreign matters such as lint contained in the air flowing in the circulation air passage 12.

The air supply duct 17 extends upward from the connection duct 16, and its upper end is connected to the air outlet 9 of the water tank 4.

  FIG. 2 schematically shows an electrical configuration of the washing / drying machine of the washing / drying machine 1 described above. The control device 18 as a control unit is configured mainly with a microcomputer, for example, and controls the operation of the washing / drying machine 1. The control device 18 inputs an operation signal from an operation panel 19 having, for example, a power-on switch, a power-off switch, and the like, and also detects a water temperature sensor 20 that detects the water temperature in the water tank 3 and a water level sensor 21 that detects the water level in the water tank 3. , A current sensor 22 as a detection unit for detecting a current flowing through the drum motor 7, a rotation sensor 23 as a detection unit for detecting the rotation of the drum motor 7 (drum 5), and a vibration as a detection unit for detecting the vibration of the water tank 3. A detection signal is input from the sensor 24. The vibration sensor 24 is provided on the outer peripheral surface of the upper part of the water tank 3, and is composed of, for example, a three-dimensional acceleration sensor. When the detection signal is input from the various sensors 20 to 24, the control device 18 analyzes the sensor value included in the input detection signal, the water temperature in the water tank 3, the water level in the water tank 3, and the current value flowing through the drum motor 7. The number of rotations of the drum motor 7 and the vibration of the water tank 3 are determined.

  Further, the control device 18 outputs a display command signal for instructing a display operation to the display unit 25, controls the display of the display unit 25, and transmits an operation command signal for instructing various operations to the drum motor 7 and a water supply device (not shown). Are supplied to a water supply valve 26, a drain valve 27 provided in a not-shown drainage channel, a circulation pump 28 provided in a not-shown circulation channel, and a heat pump unit 14, and various operations of these components are performed. Control.

  The control device 18 is connected to the communication unit 29. The communication unit 29 has, for example, a Bluetooth (registered trademark) communication function as a short-range wireless communication function, and is configured to be able to perform Bluetooth communication with a home gateway 30 installed in the home (inside the home). . That is, the communication unit 29 is capable of Bluetooth communication with the home gateway 30 because the identification information (identification code, Bluetooth address) of the home gateway 30 is registered in advance as a communication partner device of Bluetooth.

  The home gateway 30 intermittently transmits a search signal including identification information for identifying itself when the power is on. When the power of the apparatus is turned on and the communication function of the communication unit 29 is turned on, the washing / drying machine 1 can receive a search signal from the home gateway 30, and when the search signal is received, the identification included in the received search signal The information is checked against previously registered identification information, and if the identification information matches, a response signal to the search signal received from the home gateway 30 is transmitted to the home gateway 30. Thereafter, the washing / drying machine 1 performs mutual authentication with the home gateway 30 and, if the result of the mutual authentication is positive, connects the Bluetooth line, and thereafter, a predetermined data communication profile (for example, on the Bluetooth line) A PAN (Personal Area Networking Profile) is connected to enable data communication with the home gateway 30.

  The home gateway 30 is provided with an IP (Internet Protocol) address and can be connected to a server (cloud server) 32 via a wide area communication network 31 including the Internet. That is, a Bluetooth line is connected between the washing / drying machine 1 and the home gateway 30, and a wide area data communication line is connected between the home gateway 30 and the server 32 via the wide area communication network 31. The machine 1 and the server 32 are connected so that data communication is possible, and various signals can be transmitted from the washing / drying machine 1 to the server 32. The server 32 is a server managed by a manufacturer of the washing / drying machine 1, for example, receives various signals transmitted from an unspecified number of washing / drying machines 1, and collects various information included in the received various signals. By doing so, it has a function of managing the collected information in a database.

  The user terminal 33 is, for example, a tablet terminal that can be carried by the user, and has a Bluetooth communication function. If the user terminal 33 is within the Bluetooth communication range with the home gateway 30, data communication is also possible between the user terminal 33 and the home gateway 30. That is, in the above-described configuration, the home gateway 30, the washing / drying machine 1, and the user terminal 33 constitute a home network. In addition, if other household appliances used in the home such as a refrigerator, a microwave oven, a vacuum cleaner, and an air conditioner have a function equivalent to the Bluetooth communication function of the washing and drying machine 1 described above, those household appliances Equipment is also included in the home network. If the user terminal 33 has a wide area communication function, the wide area communication network between the home gateway 30 and the user terminal 33 when the user carries the user terminal 33 and goes out. Data communication is possible via the communication port 31.

Next, the operation of the above configuration will be described with reference to FIGS.
When the user operates the operation panel 19 to turn on the device, sets a predetermined operation course such as a washing / drying operation course, and specifies that the user has performed an operation to instruct the start of the operation, the control device 18 Driving is started according to a predetermined driving course set by the user (S1). When starting the operation, the control device 18 monitors the sensor values included in the detection signals input from the current sensor 22, the rotation sensor 23, and the vibration sensor 24 (S2), and determines whether or not all the courses of the driving course have been completed. It is determined (S3), the occurrence of an error is determined (S4), and the presence / absence of an error occurrence is determined (S5).

  When the control device 18 specifies that an error has occurred before completing the course of the driving course, that is, during driving (S4: YES), the control device 18 stores error information indicating the content of the error that has occurred as an error history ( S6), the operation is forcibly terminated (abnormally terminated) (S7). Then, the control device 18 transmits an error notification signal including the stored error history from the communication unit 29 to the home gateway 30 (S8), and turns off the power of the device. At this time, the control device 18 may display error information on the display unit 25 and notify the user that an error has occurred in the main body. If it is determined that an error has occurred during operation, it is possible to avoid the occurrence of a secondary error by immediately forcibly terminating the operation without continuing the operation. When it is determined that there is no possibility that a secondary error will occur, the operation is forcibly terminated only when it is determined that there is a possibility that a secondary error will occur. You may continue driving.

  When the home gateway 30 receives the error notification signal transmitted from the washing / drying machine 1, the home gateway 30 identifies the occurrence of an error during operation, and transmits the error notification signal with the server 32 and the user terminal 33 as transmission destinations. When the server 32 receives the error notification signal transmitted from the home gateway 30, the server 32 manages the error information indicated by the received error notification signal in a database. If the user terminal 33 is within the Bluetooth communication range with the home gateway 30, the user terminal 33 receives the error notification signal transmitted from the home gateway 30 and displays the error information indicated by the received error notification signal. The user can grasp the occurrence of the error by checking the error information displayed on the user terminal 33 in this way. In this case, if the error can be solved by the user himself / herself, the user can continue to use the washing / drying machine 1 by solving the error by himself / herself. However, if the error can only be resolved by a serviceman, the washing / drying machine 1 may not be used until the serviceman responds, which inconveniences the user.

  In contrast to such a malfunction, the control device 18 determines whether or not there is a sign of an error during operation and specifies that there is a sign of an error (S5: YES). Is stored as a precursor history (S9). At this time, the control device 18 may display the warning information on the display unit 25 and notify the user that there is a warning of the occurrence of an error in the main body. In addition, when it is specified that there is a sign of error occurrence during driving, the driving process can be completed by continuing the driving without forcibly terminating it immediately, but there is an error depending on the type and degree of the sign. Even if it is determined that there is a possibility that an error will occur immediately, the operation is continued only when it is determined that there is no possibility that an error will occur immediately. good.

  When the control device 18 determines that all the courses of the driving course have been completed (S3: YES), the driving is ended (S10), whether or not the precursor history is stored, that is, while the current driving course is being executed. It is determined whether or not the precursor history is stored (S11). When the control device 18 determines that the precursor history is stored (S11: YES), the controller 18 transmits a precursor notification signal including the stored precursor history to the home gateway 30 from the communication unit 29 (S12), Turn off the power.

  When the home gateway 30 receives the warning notification signal transmitted from the washing / drying machine 1, the home gateway 30 specifies that there is a warning that an error has occurred during operation, and transmits the warning notification signal with the user terminal 33 as a transmission destination. If the user terminal 33 is within the Bluetooth communication range with the home gateway 30, the user terminal 33 receives the warning notification signal transmitted from the home gateway 30 and displays the warning information indicated by the received warning notification signal. By checking the precursor information displayed on the user terminal 33 in this manner, the user can grasp the precursor of the error occurrence. That is, the user can take appropriate measures before an error occurs by grasping a sign of the occurrence of the error that is expected to occur.

  Hereinafter, a case will be exemplified in which the control device 18 determines that there is a sign of occurrence of an error during operation. The control device 18 monitors the current value of the drum motor 7 during operation, the number of rotations, the number of locks, and the number of overcurrent detections (all of which are physical quantities), and determines the presence or absence of an error occurrence during operation. Regarding the current value and the rotational speed of the drum motor 7, when the drum motor 7 is in a normal state, as shown in FIG. 4, the fluctuation width of the measured value with respect to the command value is relatively small, and the current value and the rotational speed pulsate. Is relatively small. On the other hand, when a sign of occurrence of an error begins to appear, as shown in FIG. 5, the fluctuation width of the actually measured value with respect to the command value becomes relatively large, and the degree of pulsation of the current value and the rotational speed becomes relatively large. The control device 18 utilizes the characteristics of the current value and the rotational speed, analyzes the sensor value included in the detection signal input from the current sensor 22 and the rotation sensor 23, and determines the degree of pulsation. It is possible to detect a sign of an error occurring during operation. That is, the control device 18 sets a precursor determination threshold value that is a determination criterion for the precursor of an error occurrence, compares the pulsation width with the precursor determination threshold value, and determines that the pulsation width has exceeded the precursor determination threshold value. Identifies that there are signs of occurrence.

  In this case, the control device 18 may set an assumed value that is variable according to the load applied to the drum motor 7 or aging deterioration during operation, and set the assumed value as a precursor determination threshold value. That is, the control device 18 compares the degree of pulsation of the current value and the number of rotations when the load of the laundry is relatively light or when the aging deterioration is relatively small. Therefore, the expected value may be set as a precursor determination threshold value by setting a relatively small value. On the other hand, the control device 18 compares the degree to which the load on the drum motor 7 is relatively large and the current value and the number of rotations pulsate when the laundry is relatively heavy or when the aging deterioration is relatively large. Therefore, the assumed value may be set as a precursor determination threshold value by setting a relatively large value.

  In addition, as shown in FIG. 6, the number of times the drum motor 7 is locked and the number of overcurrent detections increase as the total use time increases, as shown in FIG. The control device 18 analyzes the sensor value included in the detection signal input from the current sensor 22 or the rotation sensor 23 using the characteristics of the number of times of locking and the number of times of overcurrent detection, and the number of times of locking is calculated from the analyzed sensor value. By identifying the number of times of overcurrent detection and the degree of increase, it is possible to detect a sign of an error occurring during operation. That is, the control device 18 sets a precursor determination threshold value that is a determination criterion for an error occurrence precursor to a value smaller than an error determination threshold value that is an error occurrence determination criterion, and sets the number of locks and the number of overcurrent detections as a precursor. If it is determined that the number of locks or the number of overcurrent detections has exceeded the precursor determination threshold as compared with the determination threshold, it is specified that there is a precursor of an error occurrence. As shown in FIG. 7, the control device 18 may identify the overcurrent detection count by integrating the number of times that the current value exceeds the overcurrent determination threshold, as shown in FIG. 7.

  In this case as well, the control device 18 may set an assumed value that is variable in accordance with the load on the drum motor 7 and aging deterioration during operation, and set the assumed value as a precursor determination threshold value. That is, the control device 18 is such that the load on the drum motor 7 is relatively small and the number of locks and the number of overcurrent detections increase when the laundry is relatively light or when the aging is relatively small. Is relatively small, the assumed value may be set as a relatively small value to be used as a precursor determination threshold. On the other hand, the controller 18 has a relatively large load on the drum motor 7 when the laundry is relatively heavy or when the aging is relatively large, and the number of locks and overcurrent detection increases. Is relatively large, the assumed value may be set as a relatively large value to be used as a precursor determination threshold.

  Moreover, the control apparatus 18 determines the presence or absence of the occurrence of an error for a plurality of parts based on the sensor values of the plurality of sensors. As shown in FIG. 8, if the control device 18 uses, for example, the sensor value of the current sensor 22, the sensor value of the rotation sensor 23, and the sensor value of the vibration sensor 24, an error occurs in the drum motor 7 as described above. In addition to determining the presence / absence of a warning sign, the suspension 4 that elastically supports the water tank 3 is also checked for the presence / absence of an error occurrence.

  That is, if the sensor value of the current sensor 22, the sensor value of the rotation sensor 23, and the sensor value of the vibration sensor 24 are all normal, the control device 18 has no sign of error occurrence in both the drum motor 7 and the suspension 4. Is identified. If the sensor value of the current sensor 22 and the sensor value of the rotation sensor 23 are normal but the sensor value of the vibration sensor 24 is abnormal, the control device 18 specifies that the drum motor 7 has no sign of error occurrence. However, it is specified that the suspension 4 has a sign of error occurrence. Similarly, the control device 18 determines the presence or absence of an error occurrence sign for the drum motor 7 and the suspension 4.

As described above, according to the present embodiment, the following effects can be obtained.
In the washing / drying machine 1, when it is determined that there is a sign of an error occurrence, a sign notification signal indicating the sign of the sign is transmitted from the communication unit 29 to the home gateway 30. At the stage where an error occurrence sign appears before an error occurs, the user can be notified of this. In other words, if an error that can only be resolved by a serviceman occurs, the washing / drying machine 1 may become unusable until the serviceman responds, which may inconvenience the user, but is resolved only by the serviceman. Even if it is an error that cannot be obtained, it is possible to respond at the stage where the precursor of the occurrence of the error appears, and there is a possibility that the washing and drying machine 1 may become unusable by taking appropriate measures before the error occurs. It can be avoided. In addition, the washing / drying machine 1 determines the presence / absence of an error occurrence, and sends a warning notification signal from the communication unit 29 to the home gateway 30 only when the occurrence of an error occurrence is identified. The amount of data transmitted from the machine 1 side to the server 32 can be suppressed. Thereby, it is possible to take appropriate measures before an error occurs while reducing the processing load for transmitting information to the server 32.

  Further, by taking an appropriate measure before an error occurs, the product life can be extended and the frequency of occurrence of the error can be reduced. As a result, it is possible to expect a reduction in repair requests and complaints from the user to the product manufacturer, and a reduction in opportunities for service personnel to respond. In this way, it is possible to reduce the trouble of requesting repairs to the product manufacturer on the user side, and it is possible to simplify the response to the request from the user on the product manufacturer side.

In addition, for the drum motor 7, the current value, the number of rotations, the number of locks, and the number of overcurrent detections are monitored, and the presence or absence of an error occurrence is determined based on the monitoring results. By using physical quantities obtained from the sensor values of the existing current sensor 22 and rotation sensor 23, it is possible to determine the presence or absence of a sign without providing a new sensor.
Further, the pulsation is determined for the current value and the rotation speed, and the presence / absence of an error occurrence is determined based on the determination result of the pulsation. By using the pulsation characteristics of the current value and the rotational speed, the presence / absence of a precursor can be determined by a simple method.
In addition, an assumed value that is variable according to the load related to the drum motor 7 and aging deterioration is used as a precursor determination threshold, and the current value, the number of rotations, the number of locks, and the number of overcurrent detections are compared with the precursor determination threshold. The presence or absence was judged. The presence or absence of a precursor can be determined in consideration of the load on the drum motor 7 and aging deterioration, and the accuracy can be improved.

In addition, although the case where it applied to the washing-drying machine 1 provided with the washing function and the drying function was demonstrated above, you may apply to the washing machine which does not have a drying function, and the drying machine which does not have a washing function.
In addition, the target for determining the presence / absence of an error occurrence is not limited to the drum motor 7, but may be a water supply valve 26, a drain valve 27, a circulation pump 28, a heat pump unit 14, a compressor (not shown), A heater or the like may be used.
The home gateway 30 may be omitted, or the washing / drying machine 1 and the user terminal 33 may directly communicate with each other so that the washing / drying machine 1 directly transmits a warning notification signal or an error notification signal to the user terminal 33. . The washing dryer 1 may directly transmit an error notification signal to the server 32.
In the server 32, the error notification signal is received from the washing / drying machine 1 to exemplify the configuration in which the error information indicated by the error notification signal is managed as a database. A configuration may be adopted in which the precursor information indicated by the precursor notification signal is converted into a database and managed by reception.
