Description

Clothes treating device

Technical Field

Embodiments of the present invention relate to a laundry treating apparatus.

Background

For example, in a laundry treatment apparatus such as a washing machine, an LED operation panel in which a plurality of LEDs are arranged in parallel is used as an operation panel in some cases. In such a conventional LED operation panel, LEDs for notifying a user of an abnormality (error) related to a position with a high frequency of use, an abnormality with a high degree of importance, and the like are separately prepared. For example, as shown in fig. 30, LEDs such as a water LED101, an excess capacity LED102, a drain spot inspection LED103, a filter cleaning LED104, and a seven-segment LED105 are prepared in the tub.

The in-tub water LED101 is an LED for lighting when water at a predetermined water level or higher is filled in the tub of the washing machine, and for notifying a user of the lighting. The capacity overrun LED102 is an LED for lighting up when laundry having a weight equal to or larger than a recommended capacity is put into the washing tub during the washing or drying operation, and reporting this to the user. When the capacity overrun LED102 is turned on, a buzzer sound is sounded as the capacity overrun LED is turned on.

The drain spot detection LED103 is an LED for lighting up when the water level in the washing tub does not decrease to a predetermined water level even after a predetermined time elapses during the draining, and reporting to the user that some abnormality related to the draining has occurred. The cause of such an abnormality is, for example, clogging of a drain pipe with waste, non-insertion of the drain pipe into the drain port, or the opening of the drain pipe facing upward. When the drainage point detection LED103 is turned on, a buzzer sound is sounded in accordance with the turning on.

The filter cleaning LED104 is an LED for urging the user to clean the filter by being turned on after the drying operation is completed, after a predetermined drying operation is executed, or the like. If the drying operation is repeatedly performed, a thread end adheres to the filter, and if such thread end adhesion is accumulated, a negative effect of lowering the drying efficiency occurs. Therefore, such a filter is provided to clean the LED 104. The water LED101, the capacity overrun LED102, the drain spot check LED103, and the filter cleaning LED104 are provided in the tub, and the LEDs are provided independently of each other, because the frequency of occurrence of abnormality corresponding to these is high, and information necessary for performing the normal washing operation and the drying operation can be provided to the user.

In recent years, however, in the laundry processing apparatus, a configuration provided with a touch panel type liquid crystal operation panel has been proposed. According to the liquid crystal operation panel, when a predetermined error occurs, the abnormal information is displayed on the screen in a large size, and thus the user can easily grasp the information related to the error. Further, since more information can be displayed on the screen by the liquid crystal operation panel, for example, a description of a method of dealing with an error can be given.

Thus, the liquid crystal operation panel has advantages that cannot be obtained by the LED operation panel. However, the conventional liquid crystal operation panel has room for improvement in the following respects. That is, in the LED operation panel, when a plurality of abnormalities occur at the same time, the plurality of abnormalities can be simultaneously reported to the user. For example, if a pump abnormality occurs in the LED operation panel, "E9" as an error code corresponding to the abnormality is displayed on the seven-segment LED 105. The error of the pump abnormality is an error generated in the washing operation or the drying operation, and when the error is generated, it is considered that a water error in the tub is also generated at the same time.

In the LED operation panel, in the case where the pump abnormality and the water-in-tub error are simultaneously generated like this, "EP 3" is displayed on the seven-segment LED105, and the water-in-tub LED101 is lit, so that it is possible to report to the user that both errors are generated. That is, since the LEDs are independently arranged on the LED operation panel, even when a plurality of abnormalities occur at the same time, it is possible to easily and reliably notify the user that a plurality of errors have occurred by lighting the plurality of LEDs corresponding to the plurality of abnormalities or displaying an error code corresponding to the abnormality.

On the other hand, in the liquid crystal operation panel, since a part of display information is concentrated on the display screen, if a plurality of abnormalities occur at the same time, it is impossible to notify the user that a plurality of errors have occurred without taking any measures for the display. In addition, such measures have not been implemented in conventional liquid crystal operation panels. Therefore, in the conventional liquid crystal operation panel, there is room for improvement in visibility of information related to an error, that is, in visibility.

Hereinafter, an embodiment of a laundry treatment apparatus will be described with reference to the drawings.

As shown in fig. 1, a washing machine 1 according to the present embodiment is an example of a laundry processing apparatus that can perform operations for performing processes such as washing, rinsing, spin drying, and drying on laundry. Specifically, the washing machine 1 is capable of performing a washing operation, a drying operation, and a washing-drying operation.

The washing machine 1 is a drum-type washer-dryer having a drying function, and includes a casing 2, a door 3, a control device indicated by reference numeral 4 in fig. 2, an operation panel 5, and the like. In this case, the door 3 side of the casing 2 is defined as the front side of the washing machine 1, and the side opposite to the door 3 is defined as the rear side of the washing machine 1. In addition, a horizontal direction perpendicular to the front-rear direction is set as a left-right direction. In addition, a direction orthogonal to the front-rear direction and the left-right direction is referred to as a vertical direction.

The casing 2 constituting the main body of the washing machine 1 is formed in a rectangular box shape whose front surface is smoothly inclined. An opening 6 is provided in a central portion of the front of the housing 2. The opening 6 communicates with a not-shown rotary tub provided inside the casing 2. Through which opening 6 the laundry is taken out of or put into the rotary tub. That is, the opening 6 corresponds to a laundry inlet.

The door 3 is provided to be able to open and close the opening 6. The door 3 is opened by operating a door button not shown. A water supply port 7 is provided on the upper surface of the housing 2. The water supply port 7 is connected to a faucet of tap water serving as a water source by a water supply pipe not shown. Water from a tap of tap water is supplied into a not-shown water tub provided in the housing 2 through a water supply pipe and a water supply port 7.

The control device 4 is mainly composed of a microcomputer, for example, and controls the entire operation of the washing machine 1 by executing a computer program stored in a storage device such as a ROM. As shown in fig. 2, the control device 4 is connected to the motor 11, the drain valve 12, the water supply valve 13, the compressor 14, the blower 15, and the like. A detailed description of the motor 11 for rotating a not-shown rotary tub provided in the casing 2 will be omitted.

The drain valve 12 is used to drain water in the not-shown tub to the outside of the machine. The water supply valve 13 opens and closes the water supply port 7 to communicate with the inside of the not-shown tub, and supplies water into the tub. The compressor 14 constitutes a heat pump unit for the drying function. The blower 15 supplies the hot air generated by the heat pump unit to a not-shown rotary tub.

The control device 4 is connected to input devices such as a temperature sensor 16, a water level sensor 17, a rotation sensor 18, and a door switch 19, and the operation panel 5. Detailed descriptions are respectively omitted, in which the temperature sensor 16 detects a temperature inside the tub, not shown. The water level sensor 17 detects a water level inside the tub. The rotation sensor 18 detects a rotational position and a rotational speed of the drum, not shown. The door switch 19 detects opening and closing of the door 3.

As shown in fig. 1, the operation panel 5 is provided on the front side of the upper surface of the housing 2. The operation panel 5 includes a rectangular display unit 20 formed of, for example, a liquid crystal display. In this case, a direction along the front-rear direction of the washing machine 1 is defined as the up-down direction of the display unit 20, and a direction along the left-right direction of the washing machine 1 is defined as the left-right direction of the display unit 20.

Various screens containing various information related to the operation of the washing machine 1 are displayed on the display unit 20. The display surface of the display unit 20 also functions as a touch panel on which a user can perform a touch operation. Various screens including operation keys for accepting various operations related to the operation of washing machine 1 are displayed on display unit 20. The user can perform various operations related to the operation of the washing machine 1 by performing a touch operation on the operation keys.

As described above, the operation panel 5 is used for displaying various screens including various information related to operations and operation keys for accepting various operations related to operations, and corresponds to an operation display. In the present embodiment, a capacitance type touch panel in which a change in capacitance generated when a finger is touched is sensed by a sensor is used as the touch panel of the display unit 20. As the touch panel of the display unit 20, various types such as a resistive film type can be used. The display unit 20 is not limited to a liquid crystal display, and various display devices such as an organic EL display can be used.

The control device 4 executes a program for display control to control display on the display unit 20 of the operation panel 5. The control device 4 executes various controls such as selection of an operation type, selection of a program, setting of contents of the program, and start or temporary stop of the operation in accordance with an operation performed on the operation keys displayed on the display unit 20. In this way, the control device 4 controls the display on the display unit 20, and performs predetermined control in accordance with the operation of the operation keys, and corresponds to a control unit.

Next, the contents of the control related to the display on the display unit 20 in the above configuration will be described.

[1] Front page picture

When a power switch, not shown, is operated by a user, power is supplied to the washing machine 1. After the power is turned on, a home screen as shown in fig. 3 is displayed on the display unit 20. Hereinafter, the display unit 20 is also referred to as a screen.

The home screen is a display screen before the first input operation is performed after the power is turned on, and is a screen for selecting the operation type. In the top page screen or the like, the upper end portion of the screen becomes a common header (header) portion 21. Various status information such as the name and time of the currently selected operation, the state of locking the door 3, that is, the state of radio waves related to wireless communication with an external device, and the like are constantly displayed on the header 21.

As the state information indicating the state of locking the door, there are a door lock icon 32 indicating whether or not the locking of the door is performed, and a child safety lock icon 33 indicating whether or not the child safety lock is set. In this case, the lock icon 32 is displayed when locking is performed, and is not displayed when locking is not performed. In this case, the child safety lock icon 33 is displayed when the child safety lock is set, and is not displayed when the child safety lock is not set. In this way, the control device 4 causes the header 21, which is a predetermined area of the screen, to display various kinds of status information including the state of locking the door.

In the home screen, a washing operation icon 22 as an operation key for selecting the washing operation, a washing/drying operation icon 23 as an operation key for selecting the washing/drying operation, and a drying operation icon 24 as an operation key for selecting the drying operation are arranged in the center of the screen.

In this case, the wash operation icon 22, the wash dry operation icon 23, and the dry operation icon 24 are arranged in parallel in order from the left side of the screen. In addition, the order of arrangement of these three icons can be appropriately changed. Further, the order of arrangement of the three icons may be changed according to the selection state of the operation. For example, the arrangement of the icons may be changed as needed so that the icon selected at that time is always arranged at the center.

The wash operation icon 22, the wash dry operation icon 23, and the dry operation icon 24 correspond to a plurality of operation type icons provided corresponding to each operation type. By operating these operation type icons, the operation corresponding to the operation type icon is selected, that is, the type of operation is determined.

Specifically, the cleaning operation is selected when the cleaning operation icon 22 is operated, the cleaning/drying operation is selected when the cleaning/drying operation icon 23 is operated, and the drying operation is selected when the drying operation icon 24 is operated. In addition, such selection and determination of the operation type can be performed any number of times before the operation is started.

When a predetermined operation type icon is operated, the control device 4 causes the operated operation type icon to be displayed relatively larger than the non-operated operation type icon. When a predetermined operation type icon is operated, the control device 4 increases the operable area in which the operation for the operated operation type icon is possible relative to the operable area in which the operation for the non-operated operation type icon is possible.

For example, when the wash and dry operation icon 23 is operated, the wash and dry operation icon 23 is displayed larger than the wash operation icon 22 and the dry operation icon 24 which are not operated, as shown in fig. 3. At this time, the operable region 23a corresponding to the washing/drying operation icon 23 is larger than the operable region 22a corresponding to the washing/drying operation icon 22 and the operable region 24a corresponding to the drying operation icon 24 which are not operated.

When a predetermined operation type icon is operated, the control device 4 displays the name of the program selected for the operation corresponding to the operated operation type icon and the icon corresponding to the program. For example, when the washing and drying operation icon 23 is operated, the washing and drying operation icon 23 is changed to a display including the name of the program currently selected for the washing and drying operation (in this case, the standard program) and an icon corresponding to the program (in this case, an icon schematically showing a T-shirt), as shown in fig. 3.

The control device 4 selects an operation corresponding to a predetermined operation type icon by performing one operation on the predetermined operation type icon, and the control device 4 displays a program selection screen for selecting a program corresponding to the operation by performing another operation on the predetermined operation type icon on which the one operation has been performed. For example, as shown in fig. 3, when the washing and drying operation icon 23 is further operated in a state where the washing and drying operation icon 23 is operated once, the program is shifted to a program selection screen for selecting a program corresponding to the washing and drying operation. Although not shown in the drawings and described in detail, the program selection screen is a display capable of selecting a program while referring to the outline and the process content of the program.

In the top page screen or the like, the lower end of the screen is a common tail (footer) portion 25. The tail portion 25 is provided with a setting key 26, an illumination switch key 27, a warm water setting key 28, a reservation setting key 29, a program selection key 30, and a start key 31, which are arranged in a row in the horizontal direction of the screen from left to right. The setting key 26, the light switch key 27, the warm water setting key 28, and the reservation setting key 29 are constantly displayed in a fixed manner on various display screens before the start of operation. In addition, these four operation keys are operation keys for making settings related to the operation of the washing machine 1, and are operation keys whose frequency of use is relatively high.

The setting key 26 is an operation key for performing various settings related to the washing machine 1. When the setting key 26 is operated, the screen is changed to a setting/other screen. Various settings and the like that can be executed by setting and operation on another screen will be described later. The illumination switch key 27 is an operation key for turning on (lighting up) or turning off (extinguishing) an illumination (e.g., LED) for illuminating the inside of the tub of the washing machine 1. The illumination is turned on by the operation of the illumination switch key 27, so that the inside of the tub of the washing machine 1 is illuminated by the light of the LED, and the dark inside of the tub is made bright, which can help the user to take out and put in the laundry (clothes).

The warm water setting key 28 is an operation key for setting the temperature of water used during operation. When the hot water setting key 28 is operated, a hot water setting screen (not shown) for setting how much the water temperature is heated during the washing operation or the washing and drying operation is displayed. On the hot water setting screen, a desired setting can be selected from a plurality of hot water settings (e.g., none, 15 ℃, 30 ℃, 40 ℃, 50 ℃, 60 ℃ sterilization, etc.).

The reservation setting key 29 is an operation key for setting a reservation for operation. When the reservation setting key 29 is operated, a reservation setting screen (not shown) is displayed. In the reservation setting screen, a desired setting can be selected from a plurality of reservation settings (for example, none, morning reservation, home reservation, outside reservation, and the like). In addition, the end time of the operation can be set to a desired time on the reservation setting screen.

The program selection key 30 is an operation key for shifting to the aforementioned program selection screen. In this case, when the program selection key 30 is operated, the screen is shifted to a program selection screen for selecting a program corresponding to the operation selected at that time. For example, as shown in fig. 3, when the program selection key 30 is operated in a state where the washing and drying operation is selected, the program is shifted to a program selection screen for selecting a program corresponding to the washing and drying operation.

The start key 31 is an operation key for starting operation, and is displayed at an end portion of the screen, more specifically, at a lower right end of the screen. The control device 4 is always displayed at the same position when the start key 31 is displayed on various screens such as the home screen and the program selection screen. When the start key 31 is operated on the home screen and the program selection screen, which are screens before execution, the execution type and the execution in the program selected at that time are started. When the operation is started, an in-operation screen including all the in-operation processes including the currently-in-operation process and the operation remaining time, which is the time required until the operation is completed, is displayed.

[2] Error picture ensemble

If an error occurs as an abnormality related to the washing machine 1, the control device 4 displays an error screen including an information display area displaying information related to the error. Errors that can be generated in the washing machine 1 can be classified into three types, i.e., class E errors, class C errors, and notification-type errors.

As shown in fig. 4, the class E errors include errors related to abnormality of the rotation sensor, abnormality of disconnection of the drum, abnormality of circuit voltage of the drum motor, abnormality of water leakage (leakage of the water supply valve), abnormality of the bubble sensor, abnormality of the water level sensor, abnormality of the drain valve, abnormality of the nonvolatile memory, abnormality of the drain pump, abnormality of the door lock, and the like. Each of the E-type errors is associated with an independent display (error codes E1 to E10) for displaying on the error screen. For example, when an error (E1) relating to an abnormality of the rotation sensor occurs, if the rotation sensor value is abnormal, the rotation detection of the motor is no longer possible, and therefore the operation is immediately stopped. Thus, a class E error is an error in which operation is stopped and, if an error is generated, operation cannot be continued (restarted).

As shown in fig. 4, the class C errors include errors related to door opening abnormality, thread end filter falling off, water supply abnormality, dry filter clogging, temperature in the tub, and the like. Each of the C-type errors is associated with an independent display (error codes C1 to C5) for displaying on the error screen. For example, when an error (C26) relating to the falling of the end-of-thread filter occurs, the operation is stopped because the attachment position of the end-of-thread filter is opened and thus if the operation is continued, there is a fear that water leakage occurs. However, in this case, if the user attaches the end-of-line filter to the washing machine 1 as it is, the error can be resolved and the operation can be restarted. As described above, the class C error is an error that can restart the operation when the condition for generating the error is released although the operation is stopped.

As shown in fig. 4, the notification-type errors include errors related to clogging of the dry filter, a large amount of cloth, a water level higher than a predetermined level in the tub, abnormal drainage, cleaning of the end-of-line filter, and the like. In addition, each notification type error is associated with an independent display (filter cleaning, capacity overrun, water in the tub, drain spot check) for displaying on the error screen.

For example, when it is detected that the cloth amount existing in the tub is larger than a predetermined amount by the weight detection processing performed during the operation, an error (capacity overrun) related to the capacity overrun occurs. In this case, since there is a possibility that a trouble (insufficient washing and drying) occurs in the subsequent operation, the user is notified that the cloth amount is larger than the predetermined amount. However, in this notification, the operation state is not changed. That is, when the notification is given during the operation, the operation is continued, and when the notification is given during the operation stop, the operation stop state is maintained. In this way, the notification type error is an error that may cause some trouble, although it does not affect the operation itself.

In this case, the plurality of errors that can be generated are given priority (sorted), that is, given priority, as follows. That is, the class E error is an error that becomes a problem when the operation of the washing machine 1 is normally performed, and the importance thereof is the highest. Class C errors are less important than class E errors. In addition, notification-like errors are less important than C-like errors. In the present embodiment, the priority of each error is determined based on the importance thereof.

Thus, the highest priority class E errors are followed by higher priority class C errors, and the lowest priority class notification errors. That is, as shown in fig. 4, the priority of the E-type error is "high", the priority of the C-type error is "medium", and the priority of the notification-type error is "low". As will be described in detail later, the control device 4 controls the display of the error screen so that, when a plurality of errors occur, the display amount of information relating to an error having a relatively high priority among the plurality of errors is larger than the display amount of information relating to an error having a relatively low priority.

[3] Error picture in the case of class E error

Specifically, a screen as shown in fig. 5 can be used as the error screen displayed when the class E error occurs. Here, although the error screen displayed when an error relating to a drain pump abnormality occurs is exemplified, the same screen can be used for the error screen displayed when another class E error occurs.

In the error screen shown in fig. 5, in the upper area 34, a "failure" is displayed to indicate that the generated error corresponds to a failure. In addition, in the area 35 provided below the area 34, an error code "E9" corresponding to the drain pump abnormality is displayed as a failure code. In addition, a description indicating a coping method in this case is displayed in the area 35. These areas 34 and 35 correspond to information display areas in which information related to errors is displayed.

[4] Error picture in case of C-type error

Specifically, a screen as shown in fig. 6 or 7 can be used as the error screen displayed when the class C error occurs. Here, an error screen displayed when an error related to the missing of the end-of-line filter occurs is exemplified, and the same screen can be used for an error screen displayed when another type C error occurs. The error screen shown in fig. 6 is a screen displayed when an error occurs during execution of the operation, and the error screen shown in fig. 7 is a screen displayed when an error occurs during stop of the operation.

In the error screen shown in fig. 6 and 7, in the upper area 36, a display "end of line filter drop" indicating an abnormal position and an abnormal state regarding the generated error is displayed, and an error code "C2" corresponding to the end of line filter drop is displayed. In addition, in the area 37 provided below the area 36, a description and a figure showing a coping method in this case are displayed. These areas 36 and 37 correspond to information display areas in which information related to errors is displayed.

As shown in fig. 6, when an error occurs during execution of the operation, the restart key 38 is disposed at the lower end of the error screen displayed. The resume operation key 38 is an operation key for resuming the operation temporarily stopped due to the occurrence of an error. That is, when an error occurs during execution of the operation, the control device 4 displays an error screen including the operation restart key 38 as an operation key for restarting the operation. According to such an error screen, the user can continue the operation performed before the error is generated by operating the resume operation key 38 after the generated error is released, specifically, after the end-of-line filter is attached.

As shown in fig. 7, a close key 39 is disposed at the lower end of the error screen displayed when an error occurs during the stop of the operation. The close key 39 is an operation key for causing the displayed error screen, that is, the displayed information on the error to be non-displayed. That is, when an error occurs during the stop of the operation, the control device 4 displays an error screen including a close key 39, which is an operation key for making the displayed information on the error non-displayed, on the screen. When the off key 39 is operated to receive a command for causing information on the displayed error to be non-displayed, the control device 4 closes the displayed error screen. According to such an error screen, after the user cancels the error, specifically, after the end-of-line filter is attached, the user can close the error screen and return to the normal display screen (home screen or the like) by operating the close key 39.

[5] Error screen for notifying generation of error

Specifically, a screen as shown in fig. 8 or 9 can be used as the error screen to be displayed when the notification type error occurs. Here, the error screen displayed when an error relating to the capacity overrun and an error relating to the water in the tub occur is exemplified, but the same screen may be used for the error screen displayed when an error of another notification type occurs.

In the error screen shown in fig. 8, in the upper area 40, a display "laundry is put in too much" indicating an abnormal position and an abnormal state regarding the generated error, and an independent display "capacity overrun" corresponding to the capacity overrun is displayed. In addition, in the area 41 provided below the area 40, a description indicating a coping process in this case is displayed. These areas 40 and 41 correspond to information display areas in which information related to errors is displayed. Further, a close key 42 is disposed at the lower end of the error screen shown in fig. 8. The close key 42 is an operation key for making the displayed error screen non-displayed (closed), similarly to the close key 39.

In the error screen shown in fig. 9, in the upper area 43, a display "water remains in the drum" indicating an abnormal position and an abnormal state regarding the generated error is displayed, and an independent display "water is in the tub" corresponding to the water in the tub is displayed. In addition, in the area 44 provided below the area 43, a description indicating a coping process in this case is displayed. These areas 43 and 44 correspond to information display areas in which information related to errors is displayed.

In this case, the first half of the description indicating the coping process is displayed in the area 44 (1/2). By operating a scroll key 45 provided at the right end of the lower part of the error screen, the second half (2/2) of the description indicating the coping process can be displayed in the area 44. In a state where the second half (2/2) of the description indicating the coping process is displayed in the area 44, the first half (1/2) of the description indicating the coping process can be displayed in the area 44 by operating the scroll key 46 provided on the left side of the scroll key 45. Further, a close key 47 is disposed at the lower left end of the error screen shown in fig. 9. The close key 47 is an operation key for turning the displayed error screen off, similar to the close key 42.

[6] Error picture (1) when generating a plurality of errors having different priorities

When another error having a higher priority than the predetermined error occurs while the error screen corresponding to the predetermined error is being displayed, the control device 4 changes the display mode of the error screen so that at least a part of the information relating to the predetermined error is not displayed and the information relating to the other error having the higher priority is displayed.

For example, in a case where an abnormality related to a class E error (e.g., a drain pump abnormality) occurs in a state where an error screen related to a notification type error (e.g., an excess capacity, water in a tank, etc.) is displayed due to an abnormality related to the notification type error (e.g., a capacity overrun, water in a tank, etc.), the error screen related to the notification type error is not displayed regardless of the operation of the close keys 42 and 47, and instead, an error screen related to the class E error as shown in fig. 5 is displayed.

[7] An error picture (2) for generating a plurality of errors having different priorities

As described above, when a predetermined error occurs during execution of the operation, the control device 4 displays an error screen including a restart key for restarting the operation. When another error having a higher priority than the predetermined error occurs in a state where the error screen including the restart key is displayed, the control device 4 changes the display mode of the error screen so that the restart key is covered with the information display area in which the information on the other error having the higher priority is displayed.

For example, in a case where an abnormality related to a class C error (e.g., a line head filter falling) occurs during execution of the operation and an error screen such as that shown in fig. 6 is displayed, and an abnormality related to a class E error (e.g., a drain pump abnormality) having a higher priority is generated, information related to the class E error is displayed so as to cover at least the restart key 38. Specifically, instead of the error screen shown in fig. 6, an error screen corresponding to a class E error of the type shown in fig. 5 is displayed. In this case, as shown in fig. 10, the restart operation key 38 is covered with the area 35 in the error screen corresponding to the class E error.

[8] An error picture (3) for generating a plurality of errors having different priorities

When an error having a relatively high priority (hereinafter, referred to as a first error) and an error indicating an abnormality having a relatively low priority and possibly causing the first error (hereinafter, referred to as a second error) occur, the control device 4 controls the display of the error screen so that information related to the first error is displayed and a part of information related to the second error is displayed. Further, as the first error, for example, an error indicating a water leakage abnormality can be cited. The second error may be, for example, an error in which the end-of-line filter is removed.

For example, when a water leakage abnormality of higher priority is generated in a state where an abnormality related to the removal of the end-of-line filter occurs during the execution of the operation and an error screen as shown in fig. 6 is displayed, an error screen as shown in fig. 11 is displayed. The error screen shown in fig. 11 is provided with the same regions 34 and 35 as those of the error screen corresponding to the class E error shown in fig. 10. However, in this case, an area 48 is provided above the area 34, in which the same contents as the area 36 in the error screen with the filter missing as shown in fig. 6 are displayed. With such an error screen, the user can recognize that an error occurs in which the end-of-line filter is removed in addition to an error in which a water leakage abnormality occurs.

[9] Error picture when generating multiple errors having equal priority

When another error having the same priority as the predetermined error occurs while the error screen corresponding to the predetermined error is displayed, the control device 4 maintains the display of the information relating to the predetermined error. Then, if a condition for eliminating the predetermined error is satisfied or a close key corresponding to the predetermined error is operated thereafter, the control device 4 changes the display mode of the error screen so that information on another error having the same priority is displayed.

For example, in a case where an abnormality related to the presence of water in the bucket is generated as a notification type error and an error screen as shown in fig. 9 is displayed, and an abnormality related to the capacity overrun having the same priority as the abnormality related to the presence of water in the bucket is generated, the display mode of the error screen is changed as shown in fig. 12. As shown in fig. 12, in this case, the display of the information related to the error of the presence of water in the tub is, although its size is reduced slightly in the longitudinal direction, maintained as it is with respect to the display contents.

In this case, a part of the error screen with the capacity overrun shown in fig. 8, specifically, the area 40 is displayed at the upper end of the error screen. In this way, when a plurality of errors having the same priority level occur, the display of information relating to the error that occurred first (water in the bucket) is maintained, and a part of the information relating to the error that occurred later (capacity overrun) is displayed.

In this case, the information on the error (water in the tub) generated first is displayed with higher visibility than the information on the error (capacity overrun) generated later. Specifically, in this case, the areas 43 and 44 displaying the information corresponding to the error (water in the tub) generated first are displayed on the lower side of the screen, i.e., on the user side, than the area 40 displaying the information corresponding to the error (capacity overrun) generated later. Further, if there is no problem in visual recognition, the regions 43 and 44 displaying the information corresponding to the error generated first may be displayed closer to the upper side of the screen than the region 40 displaying the information corresponding to the error generated later.

In a case where a condition for eliminating an error of water in the tub is satisfied in a state where the error screen as shown in fig. 12 is displayed, or in a case where the control device 4 receives a command for making information (error screen) about the error of water in the tub non-displayed due to the off key 47 being operated, information about the error of water in the tub is non-displayed, and only information about the error of the capacity overrun is displayed. Specifically, in this case, an error screen corresponding to an error of the capacity overrun as shown in fig. 8 is displayed.

In addition, it is extremely rare that a plurality of errors are generated at the same time, but if a plurality of errors having the same priority are generated at the same time, the order of generation of the errors is defined as follows in the present embodiment. That is, the control device 4 determines whether or not each error has occurred in the table shown in fig. 4 in the order from top to bottom. Therefore, when a plurality of errors having the same priority are generated at the same time, the order of generation of the errors is defined, and the error higher in the table shown in fig. 4 is generated first.

[10] Error picture corresponding to error of temperature (water temperature) in barrel

When an abnormality related to the in-tub temperature (water temperature) occurs, a screen as shown in fig. 13 or 14 can be specifically used as the error screen. For example, if the operation is temporarily stopped during the operation of heating the water temperature, an error screen as shown in fig. 13 is displayed. In the error screen shown in fig. 13, in the upper area 49, a display "the water temperature in the drum is high" indicating an abnormal position and an abnormal state concerning the generated error is displayed, and an independent display "C6" corresponding to the temperature (water temperature) in the tub is displayed.

In addition, in the area 50 provided below the area 49, information on a coping method in this case, specifically, a method of eliminating an error in the temperature (water temperature) in the tub is displayed. These areas 49 and 50 correspond to information display areas in which information relating to errors is displayed. Further, a restart key 51 is disposed on the right side of the lower end portion of the error screen shown in fig. 13. The resume operation key 51 is an operation key for resuming the operation that has been temporarily stopped, similarly to the resume operation key 38 described above. The user can restart the running in execution by operating the restart running key 51.

A cooling and dehydrating execution key 52 is disposed on the left side of the lower end portion of the error screen shown in fig. 13. The cooling dehydration execution key 52 is an operation key for executing a cooling dehydration operation different from the operation being executed, and corresponds to an elimination operation execution key, and the cooling dehydration operation is an operation for eliminating an error in the temperature (water temperature) in the tub. The user can perform the cooling and dehydrating operation by operating the cooling and dehydrating execution key 52, and the water temperature in the tub is lowered to open the door 3. In this way, when a predetermined error occurs during execution of the operation, the control device 4 displays an error screen including information on a method for canceling the predetermined error and an cancel operation execution key for executing the operation for canceling the predetermined error, which is different from the operation being executed.

For example, if the power supply of washing machine 1 is temporarily turned off and then turned on again for some reason during the operation of heating the water temperature, an error screen as shown in fig. 14 is displayed. The error screen shown in fig. 14 is different from the error screen shown in fig. 13 in that the restart key 51 is not provided. In this case, the restart key 51 is not displayed because the restart cannot be started in any case. Thus, in this case, the user can perform the cooling and dehydrating operation by operating the cooling and dehydrating execution key 52, and the water temperature in the tub is lowered to open the door 3. In the error screen shown in fig. 13 and 14, the display of the area 50, that is, the display of information on a method of eliminating an error in the temperature (water temperature) in the tub is not essential, and can be omitted.

[11] Error screen corresponding to error of temperature (temperature) in barrel

When an abnormality related to the temperature (temperature) in the tub occurs, a screen as shown in fig. 15 or 16 can be specifically used as the error screen. For example, if the operation is temporarily stopped when the temperature in the tub is high during the execution of the drying operation, an error screen as shown in fig. 15 is displayed. In the error screen shown in fig. 15, a display "temperature inside drum becomes high" indicating an abnormal position and an abnormal state with respect to the generated error is displayed in the upper area 53, and an independent display "C5" corresponding to the temperature (temperature) inside the tub is displayed.

In addition, in the area 54 provided below the area 53, information on a coping method in this case, specifically, a method of eliminating an error in the temperature (temperature) in the tub is displayed. These areas 53 and 54 correspond to information display areas in which information related to errors is displayed. Further, a restart key 55 is disposed at the lower end of the error screen shown in fig. 15. The resume operation key 55 is an operation key for resuming the operation that has been temporarily stopped, similarly to the resume operation key 51 and the like described above. The user can restart the running in execution by operating the restart running key 55.

For example, when the temperature in the tub is high when the washing machine 1 is powered on, an error screen as shown in fig. 16 is displayed. The error screen shown in fig. 16 is different from the error screen shown in fig. 15 in that the restart key 55 is not provided. In this case, the restart key 55 is not displayed since the restart cannot be started at all. Thus, in this case, the user waits for the temperature inside the tub to be lowered by the automatically performed blowing operation.

When the error screen shown in fig. 15 or 16 is displayed, a part of the head 21 is exposed. That is, when the error screen shown in fig. 15 or 16 is displayed, the control device 4 is set to a state in which at least a part of the state information is exposed. In this case, a temperature icon 56 indicating the temperature inside the tub is displayed on the head 21 in addition to the door lock icon 32, the child safety lock icon 33, and the like. The door lock icon 32, the child safety lock icon 33, and the temperature icon 56 are visually recognizable to what degree they respectively represent. With such display, the user can grasp whether or not the door is locked, the temperature in the tub at the present time, and the like, and as a result, can estimate how long the door 3 will last (execution of the air blowing operation).

[12] Error picture when generating multiple errors

When a plurality of errors occur, the control device 4 controls the display of the error screen so that at least a part of information related to the errors is displayed for each of the plurality of errors. For example, when an abnormality related to the falling of the end-of-line filter occurs and an error screen such as that shown in fig. 7 is displayed, an abnormality related to the capacity overrun and an abnormality related to the presence of water in the tub occur, an error screen such as that shown in fig. 17 is displayed.

In the error screen shown in fig. 17, the display of the information relating to the filter-out of the end of line is, although its size is reduced slightly in the longitudinal direction, maintained as it is with respect to the display content. In this case, a part of the error screen with the capacity overrun shown in fig. 8, specifically, the area 40 is displayed at the upper end of the error screen. In this case, a part of the error screen showing that water is present in the tub, specifically, the area 43 shown in fig. 9 is displayed below the area 40. In this way, when a plurality of errors are generated, error-related information having a relatively high priority is displayed with higher visual recognizability than error-related information having a relatively low priority. In this case, if the priorities of all errors are equal, the display of the information on the error generated first is maintained, and a part of the information on the error generated later is displayed.

Therefore, in this case, the regions 36 and 37 displaying information corresponding to an error with a relatively high priority (head of thread filter falling off) are displayed closer to the lower side of the screen, that is, closer to the user side than the regions 40 and 43 displaying information corresponding to an error with a relatively low priority (capacity overrun, water in the tub). Further, if there is no problem in visual recognizability, the regions 36 and 37 displaying information corresponding to errors having a relatively high priority may be displayed closer to the upper side of the screen than the regions 40 and 43 displaying information corresponding to errors having a relatively low priority.

In this case, the regions 40 and 43 also function as touch recognition regions for recognizing a touch operation by the user. For example, when the area 43 is operated in the error screen shown in fig. 17, the display mode of the error screen is changed as shown in fig. 18. In the error screen shown in fig. 18, the areas 43 and 44 indicating the information that water is present in the bucket corresponding to the operated area 43 are displayed so as to be relatively large from the center of the screen toward the lower side. In this case, a part of the error screen in which the filter is dropped, specifically, the area 36 shown in fig. 7 is displayed below the area 40. In this way, when the touch recognition area is operated, the error-related information corresponding to the touch recognition area is displayed in a close-up and relatively large size, and a part of the other error-related information is displayed in a relatively small size.

[13] Settings and other screens

As described above, in the home screen or the like, when the setting key 26 is operated, the screen is changed to the setting/other screen. As shown in fig. 19, a return key 60 is provided at the upper left end of the setting/other screen. The return key 60 is an operation key for returning to the previous screen. Four icons 61-64 are arranged in an area below the return key 60.

The setting key 77 functions as an operation key for displaying a screen for setting a finish comfort mode in which the hard feeling after drying in the sun can be suppressed. When the setting key 77 is operated, the operation proceeds to a "washing method setting screen" as shown in fig. 23. The "washing method setting screen" is a screen that can be changed even when the icon 63 is operated on the main body or other screen.

A return key 78 is provided at the upper left end of the "washing method setting screen". The return key 78 is an operation key for returning to the previous screen. Five label icons 79 to 83 corresponding to the "silent mode setting", "water storage rinsing mode setting", "energy saving mode setting", "finish comfort mode setting", and "quality dry mode setting" are arranged in this order from top to bottom on the left side of the area below the return key 78. The right area 84 of these tab icons 79-83 displays the content corresponding to the operation performed on the tab icons 79-83.

When the screen shown in fig. 22 is changed to the "washing method setting screen" by operating the setting key 77, the tab icon 82 is operated as shown in fig. 23. If the tag icon 82 is operated, the description about the completion of the comfort mode is displayed in the area 84. In this case, a setting switch key 85 is disposed in the region 84.

The setting switch key 85 is an operation key for completing the setting of the comfort mode. The user can switch between a state in which the comfort mode is completed and a state in which the comfort mode is not completed by operating the setting switch key 85. When the comfort mode is set, the set on-off key 85 is on as shown in fig. 23. In the case where the completion comfort mode is set by such an operation, the set state is not reset after the operation, but is maintained regardless of the number of execution of the operation, the switching of the power supply of the main body of the washing machine 1, and the like. That is, such setting may affect all operations performed after the setting is made.

According to the above-described screen transition flow, when the user feels the hard feeling of mind of drying out, in the process of searching for a point of his/her own intention from the column of the "common inquiry" of the "convenient-to-understand screen", a screen (washing method setting screen) for performing the setting of the comfort mode for reducing the hard feeling of drying out can be displayed, and the setting can be performed. Therefore, according to the present embodiment, an effect of improving the convenience of the user can be obtained.

The icon 71 functions as an operation key for displaying and setting information corresponding to the case of "forming wrinkles after drying". Specifically, when the icon 71 is operated, a screen as shown in fig. 24 is displayed. The first half of the information corresponding to the case of "forming many wrinkles after drying" is displayed in the central area 86 of the screen shown in fig. 24 (1/2). By operating a scroll key 87 provided at the right end of the lower part of the screen shown in fig. 24, the latter half of the information can be displayed in an area 86 as shown in fig. 25 (2/2).

The setting key 90 functions as an operation key for displaying a screen for setting a quality drying mode in which wrinkles are prevented from being formed after drying. When the setting key 90 is operated, the operation is changed to the "washing method setting screen" described above. When the setting key 90 is operated on the screen shown in fig. 25 to shift to the "washing method setting screen", the tab icon 83 is operated as shown in fig. 26. When the label icon 83 is operated, the description about the quality drying mode is displayed in the area 84. In this case, a setting switch key 91 is disposed in the region 84.

The setting switch key 91 is an operation key for setting the quality drying mode. The user can switch between a state in which the quality drying mode is set and a state in which the quality drying mode is not set by operating the setting switch key 91. When the high-quality drying mode is set, the setting switch key 91 is set to display "on" indicating that the mode is set, as shown in fig. 26. In the case where the quality drying mode is set by such an operation, the set state is not reset after the operation, but is maintained regardless of the number of execution of the operation, the switching of the power supply of the main body of the washing machine 1, and the like. That is, such setting may have an influence on the entire operation performed after the setting is made.

According to the flow of screen transition described above, when the user feels that wrinkles have formed after drying, the user can display the screen (washing method setting screen) for performing the setting of the good-quality drying mode for reducing wrinkles after drying in the process of searching for a point of his/her own intention from the column of the "general inquiry" of the "convenient-to-understand screen", and can perform the setting. Therefore, according to the present embodiment, an effect of improving the convenience of the user can be obtained.

The icon 72 functions as an operation key for displaying and setting information corresponding to the case where "vibration is large and abnormal noise is generated". Specifically, when the icon 72 is operated, a screen as shown in fig. 27 is displayed. A part of information (description and drawings) corresponding to the case of "large vibration and abnormal noise generation" is displayed in the central region 92 of the screen shown in fig. 27 (1/4). The remaining part of the information can be displayed in the area 92 by operating the scroll key 93 provided at the right end of the lower part of the screen shown in fig. 27.

Further, a close key 95 is disposed at the left end of the lower portion of the screen shown in fig. 27 and 28. The close key 95 is an operation key for making the displayed screen non-displayed.

A setting key 96 is disposed in the area 92 of the screen shown in fig. 28. The setting key 96 functions as an operation key for displaying a screen for setting a silent mode in which vibration during dehydration can be suppressed. When the setting key 96 is operated, the operation is changed to the "washing method setting screen" described above. When the setting key 96 is operated on the screen shown in fig. 28 to shift to the "washing method setting screen", the tab icon 79 is operated as shown in fig. 29. When the tag icon 79 is operated, the description about the silent mode is displayed in the area 84. In this case, a setting switch key 97 is disposed in the region 84.

The setting switch key 97 is an operation key for setting the silent mode. The user can switch between a state in which the mute mode is set and a state in which the mute mode is not set by operating the setting switch key 97. When the mute mode is set, as shown in fig. 29, the setting switch key 97 is set to display an on mode indicating that. In the case where the silent mode is set by such an operation, the set state is not reset after the operation, but is maintained regardless of the number of execution of the operation, the switching of the power supply of the main body of the washing machine 1, and the like. That is, such setting may affect all operations performed after the setting is made.

According to the flow of screen transition described above, when the user feels that the vibration is large and the abnormal noise is generated, the user can display the screen (washing method setting screen) for performing the silent mode setting for reducing the vibration during the spin-drying process and perform the setting while searching for the point of his/her own intention from the column of the "general inquiry" of the "easy-to-understand screen". Therefore, according to the present embodiment, an effect of improving the convenience of the user can be obtained.

According to the present embodiment described above, the following effects can be obtained.

The control device 4 gives priority to a plurality of errors that can be generated, and when a plurality of errors occur, controls the display of the error screen so that the display amount of information relating to an error having a relatively high priority among the plurality of errors is larger than the display amount of information relating to an error having a relatively low priority. In this way, the information relating to the error having the high priority (importance) is not buried in the information relating to the error having the low priority (importance), and the information relating to the error having the high importance can be reliably notified to the user. As described above, according to the present embodiment, it is possible to eliminate the drawbacks of the conventional liquid crystal operation panel, and to enjoy the benefits of the liquid crystal operation panel and further improve the visibility of errors.

When another error having a higher priority than the predetermined error occurs while the error screen corresponding to the predetermined error is displayed, the control device 4 changes the display mode of the error screen so that at least a part of the information related to the predetermined error is not displayed and displays the information related to the other error. In this way, the user can be more reliably notified of information relating to the error having a high degree of importance. Therefore, the user can cope with the error having a high degree of importance, particularly, the error which may cause a trouble in the main body or the operation of the washing machine 1, in the highest priority.

When a predetermined error occurs, the control device 4 displays an error screen including a close key (39, 42, 47) which is an operation key for making information relating to the predetermined error non-displayed. When another error having the same priority as the predetermined error occurs while the error screen is displayed, the control device 4 maintains the display of the information relating to the predetermined error.

Then, when the condition for eliminating the predetermined error is satisfied or the close key corresponding to the predetermined error is operated, the control device 4 changes the display mode of the error screen so that information related to another error is displayed. In this way, since the information on a plurality of errors of the same priority is sequentially displayed in the order of their generation, the user can sequentially handle (release) these errors.

When a predetermined error occurs during execution of the operation, the control device 4 displays an error screen including a restart operation key (38) which is an operation key for restarting the operation. In this way, after the user cancels the predetermined error, the user can promptly restart the operation without being confused about the response to the error. When another error having a higher priority than the predetermined error occurs while the error screen is displayed, the control device 4 changes the display mode of the error screen so that the information display area (area 35) in which the information related to the other error is displayed covers the operation restart key. In this way, when an error of high importance occurs such that the operation cannot be resumed or is not permitted to be resumed, the operation is not resumed by an error, and the safety can be further improved.

When a predetermined error occurs during execution of the operation, the control device 4 displays an error screen including information on a method for canceling the predetermined error and an cancel operation execution key (the cooling/dewatering execution key 52) for executing an operation for canceling the predetermined error, which is different from the operation during execution. In this way, the user can execute an operation for eliminating the error generated unlike the operation under execution by simply operating the operation-elimination execution key displayed on the error screen without requiring a complicated operation, thereby eliminating the error.

The control device 4 displays state information (a door lock icon 32 and a child safety lock icon 33) indicating the locked state of the door 3 on the head portion 21, which is a predetermined region of the display unit 20, and when an error screen is displayed, at least a part of the state information is exposed. In this way, when the user displays an error screen and fails to open the door 3, the user can easily grasp the cause (the cause of the failure to open the door 3) by checking the state information.

The control device 4 controls the display of the error screen such that, when a plurality of errors occur, at least a part of information relating to the error is displayed for each of the plurality of errors. In this way, when a plurality of errors occur, even if one piece of error-related information is displayed in a close-up manner, the user can grasp that another error has occurred in addition to the error.

The control device 4 controls the display of the error screen so that, when a first error (for example, a water leakage abnormality) which is an error having a relatively high priority and a second error (for example, an error in which a filter is dropped off) which has a relatively low priority and is a cause of the first error are generated, information relating to the first error is displayed, and a part of information relating to the second error is displayed. Thus, the user, the repair staff, or the like can immediately recognize that the cause of the first error (water leakage abnormality) is likely to be the second error (the filter at the end of the thread is removed), and can quickly eliminate the first error (water leakage abnormality).
