Description

Clothes treating device

The present application is based on Japanese patent application No. 2015-243339 (application date: 2015, 12, month and 14), and enjoys the benefit of priority of the application. This application is incorporated by reference into this application in its entirety.

Technical Field

The present invention relates to a laundry treating apparatus.

Background

In a laundry treatment apparatus such as a washing machine, a dryer, a washing and drying machine, which performs washing, dehydrating, and drying of laundry, various treatments are performed by various mechanical forces according to a treatment course preset according to the material of the laundry and a treatment content set by a user.

In such a laundry processing apparatus, a user determines the type of laundry, and sets a processing course and processing contents based on the determination. However, it is not clear to which of the symbols representing the care of the textile product the given treatment course and treatment content apply a mechanical force to the laundry. Therefore, there is a problem that it is difficult for the user to set a proper treatment course and treatment content of the mechanical force with respect to the clothes to be treated.

In JIS L0001: 2014 "expression symbol and expression method for fiber product maintenance" published on 10/20/2014, upper limit information indicating the most drastic treatment and operation that does not cause unrecoverable damage is required, instead of indicating preferred treatment contents for the fiber product as in JIS L0217: 1995 so far. In this way, the information indicated by the indication symbol may be changed greatly in the future, and there is a problem that it becomes difficult for the user to set the process progress and the process content of the appropriate mechanical force.

Further, japanese patent application laid-open No. 2008-287525 proposes the following: the laundry information is read from an identification code indicating a tag attached to the laundry or the like, and the washing apparatus is controlled based on the laundry information. The following is proposed in japanese patent laid-open No. 2002-: and obtaining proper washing machine control information corresponding to the commodity through a commodity label to control the washing machine, wherein the commodity label is provided with an information recording unit for recording commodity maintenance information. In these prior arts, there is a problem that a high-grade information processing apparatus is required and manufacturing cost is consumed.

Disclosure of Invention

Accordingly, an object of the present invention is to provide a laundry treating apparatus that allows a user to easily select a treating course and a treating content corresponding to a symbol indicating the maintenance of a textile product.

In the laundry processing apparatus according to the present embodiment, the laundry processing apparatus sets at least one of a washing process, a spin-drying process, and a course content to be executed in the processes, and executes the set processes, includes: a storage unit for storing the processing and the travel contents in association with a symbol indicating maintenance of the textile product; a display unit that displays the representation symbol; and a control unit that acquires the indication symbol corresponding to the set process and the travel content from the storage unit and causes the display unit to display the acquired indication symbol.

The drive circuit 54 is a generic term for drive circuits of respective corresponding devices.

In the washing machine 1 of the present embodiment, a washing course (washing operation), a drying course (drying operation), and a washing-drying course (washing-drying operation) are set as the fully automatic courses.

The washing process is a process of sequentially performing a washing process and a dehydration process, the washing process performs a washing process and a rinsing process, and the dehydration process performs a dehydration process.

In the washing machine 1, the contents of the washing process, the rinsing process, and the dehydrating process are different, and a plurality of washing courses having different mechanical forces (loads) applied to the laundry accommodated in the spin basket 6 are set, for example, six washing courses of "standard", "soak", "quick", "memory", "gentle", and "blanket" as shown in fig. 5 are set.

The "standard" procedure is the following procedure: as the course contents of the washing course, the water flow was set to "3" and the washing time was set to "8 minutes"; as the stroke contents of the rinsing stroke, the water flow is set to "3" and the number of times of rinsing is set to "2"; as the course content of the dehydration course, the dehydration time was set to "7 minutes". In addition, the strength of the water flow can be set to five levels, "1" weakest, "5" strongest.

The "soak" procedure is the following procedure: as the course contents of the washing course, the water flow is set to "3" and the washing time is set to "60 minutes"; as the stroke contents of the rinsing stroke, the water flow is set to "3" and the number of times of rinsing is set to "4"; as the course content of the dehydration course, the dehydration time was set to "9 minutes".

The "fast" process is the following process: as the course contents of the washing course, the water flow is set to "2" and the washing time is set to "5 minutes"; as the stroke contents of the rinsing stroke, the water flow is set to "2" and the number of times of rinsing is set to "1"; as the course content of the dehydration course, the dehydration time was set to "5 minutes".

The "memory" process is a process for executing the contents of the stroke (washing time, intensity of washing water flow, rinsing frequency, intensity of rinsing water flow, dehydration time, etc.) preset by the user. In addition, since the contents of the trip of the "memorization" process vary according to the setting of the user, the description of the "memorization" process is omitted in fig. 5.

In addition, the "standard", "soak", "quick" and "memory" processes are set to be the same among the processes by changing the intensity of the water flow and the washing time in the washing process, changing the intensity of the water flow and the number of times of rinsing in the rinsing process, and changing the dehydration time in the dehydration process, thereby changing the operation intensity (load) of each process, and other conditions (for example, the time for operating and stopping the agitator 10 in the washing process and the rinsing process, the rotation speed of the spin basket 6 in the dehydration process, and the like).

In the "soft" course, as the course content of the washing course, the "soft washing" is set, and the washing time is "7 minutes"; as the stroke content of the rinsing stroke, "soft rinsing" is set, and the number of times of rinsing is "2 times"; the contents of the dewatering course were set to "gentle dewatering" and the dewatering time was set to "5 minutes". Here, the "delicate washing" and the "delicate rinsing" are strokes in which the rotation time of the agitating body 10 is short and the mechanical force applied to the laundry is small, compared to the washing stroke and the rinsing stroke performed in other courses. In addition, the "soft dehydration" is a stroke in which the number of rotations of the spin basket 6 is low and the mechanical force applied to the laundry is small, compared to the dehydration stroke performed in other courses.

The "blanket" process is the following process: as the course content of the washing course, the washing time was set to "12 minutes"; as the stroke content of the rinsing stroke, the number of times of rinsing is set to "2 times"; as the course content of the dehydration course, the dehydration time was set to "7 minutes". In addition, although the dewatering course of the "felt" course is set to be the same as the dewatering courses of the "standard", "soak", "quick", and "memory" for conditions other than the dewatering time, the conditions such as the rotation-stop time of the pulsator 10 in the washing course and the rinsing course of the "felt" course are different from those in other courses.

The drying course is a course for executing the drying process (drying course), and a plurality of courses having different course contents of the drying course executed in the drying process are set, for example, six drying courses of "standard (strong)", "standard (weak)", "fine", "ironing", "timing (30 minutes)", and "maintaining" are set. In the drying process, high-temperature drying with the exhaust temperature higher than 60 ℃ is performed by 'standard (strong)', 'fine' and 'ironing', and low-temperature drying with the exhaust temperature below 60 ℃ is performed by 'standard (weak)', 'timing (30 minutes)', and 'maintaining'.

The washing-drying course is a course in which washing treatment (washing course and rinsing course), dehydration treatment (dehydration course), and drying treatment (drying course) are sequentially performed, and is a course in which the washing course and the drying course are set in combination.

In the washing machine 1, in addition to the above-described full-automatic course, a manual operation in which the operation intensity (mechanical force applied to the laundry) is arbitrarily set by the user in each course by changing the intensity of the water flow in the washing course and the rinsing course, the execution time of the washing course and the spin-drying course, the number of times of repetition of the rinsing course, and the like can be set.

In such a washing machine 1, the process performed by the washing machine 1 and the contents of the course performed in the process are similar to JISL 0001:2014, the reference numerals for the maintenance of the fiber product (hereinafter, also simply referred to as "reference numerals") are stored in association with each other in the memory 46a provided in the control device 46. Further, the "symbol number" described below means JIS L0001: 2014 each reference numeral is defined.

Specifically, as illustrated in fig. 6 (a), a washing process symbol group MA including a plurality of washing process symbols M140, M130, M141, M131, M142, M132, M110, and M100 corresponding to the symbol numbers 140, 130, 141, 131, 142, 132, 110, and 100 is stored in the memory 46a in association with the washing process.

As for the stroke contents of the washing stroke and the rinsing stroke executed in the washing process, one or more washing process symbols corresponding to the mechanical force applied to the laundry accommodated in the spin basket 6 by the stroke contents are selected from the washing process symbol group MA, and the stroke contents are stored in the memory 46a corresponding to the selected washing process symbols.

The washing process symbol M140 corresponds to the stroke content in which the mechanical force (load) applied to the laundry is stronger than the washing process symbols M141, M142, and M110, and corresponds to the stroke content which is gradually decreased in the order of the washing process symbols M140, M141, M142, and M110. The washing process symbol M130 corresponds to the stroke content in which the mechanical force applied to the laundry is stronger than the washing process symbols M130, M131, and M132, and corresponds to the stroke content in the order of the washing process symbols M130, M131, and M132, which is gradually decreased. In addition, the washing process symbols M140, M141, M142, and M110 correspond to a washing stroke and a rinsing stroke by the washing water having a higher temperature than the washing process symbols M130, M131, and M132.

For example, as shown in fig. 7 (a), when the water flows in the washing stroke and the rinsing stroke are set to "1", the stroke contents of the washing stroke and the rinsing stroke executed in the washing process are associated with the reference symbols.

That is, in the contents of the washing process in which the time of the washing process (washing time) is set to 0 to 6 minutes and the number of times of rinsing is set to 2 or less, two washing process symbols M142 and M132 correspond to each other.

The washing process symbols M141, M131 correspond to the contents of a washing course in which the time of the washing course is set to 7 to 10 minutes and the number of times of rinsing is set to 3 or less, the contents of a washing course in which the time of the washing course is set to 1 to 9 minutes and the number of times of rinsing is set to 3, and the contents of a washing course in which the time of the washing course is set to 1 to 8 minutes and the number of times of rinsing is set to 4.

The washing process symbols M140 and M130 correspond to the contents of a washing course in which the time of the washing course is set to 11 to 12 minutes and the number of times of rinsing is set to 2 or less, the contents of a washing course in which the time of the washing course is set to 10 to 12 minutes and the number of times of rinsing is set to 3, and the contents of a washing course in which the time of the washing course is set to 9 to 12 minutes and the number of times of rinsing is set to 4.

When the water flows in the washing stroke and the rinsing stroke are set to "2" to "5", as shown in (b) to (e) of fig. 7, the washing process symbol corresponds to a combination of the washing time in the washing stroke and the number of times of rinsing in the rinsing stroke, as in the case where the water flow is "1".

In the "soft washing" and the "soft rinsing" set in the "soft" of the washing course, the washing treatment symbol M110 corresponds to regardless of the washing time and the number of times of rinsing.

In the washing and rinsing courses set by the "carpet" of the washing course, the washing courses correspond to the washing process symbols M142 and M132 regardless of the washing time and the number of times of rinsing.

In this example, although the case where the corresponding washing process symbol is set from the washing process symbol group MA according to the washing time, the rinsing frequency, and the water flow intensity has been described, the washing process symbol may be set according to at least one of the washing time, the rinsing frequency, and the water flow intensity, or the washing process symbol may be set according to whether or not the bath water is used, or the type of the rinsing stroke (the water storage rinsing or the shower rinsing).

As illustrated in fig. 6 (b), a dehydration symbol group MB made up of a plurality of dehydration symbols M440, M445, M430, M435, M420, 425, 410, 415 corresponding to the symbol numbers 440, 445, 430, 435, 420, 425, 410, 415 is stored in the memory 46a in correspondence with the dehydration processing.

As for the stroke content of the dehydrating stroke executed in the dehydrating process, one or more dehydrating process symbols corresponding to the mechanical force applied to the laundry accommodated in the rotary tub 6 by the stroke content thereof are selected from the dehydrating process symbol group MB, and the stroke content thereof is stored in the memory 46a corresponding to the selected dehydrating process symbols.

The dehydration process symbol M440 corresponds to a stroke content in which a mechanical force applied to the laundry is stronger than the dehydration process symbols M420, M430, and M410, and corresponds to a stroke content which is faded out in the order of the dehydration process symbols M440, M420, M430, and M410. The dehydration symbol M445 corresponds to the stroke content in which the mechanical force applied to the laundry is stronger than the dehydration symbols M425, M435, and M415, and corresponds to the stroke content which is faded out in the order of the dehydration symbols M445, M425, M435, and M415.

For example, as shown in fig. 8, the spin-drying process symbols M420 and M425 correspond to the execution time (spin-drying time) of the spin-drying process of 1 to 4 minutes, the spin-drying process symbols M440 and M445 correspond to the execution time (spin-drying time) of the spin-drying process of 5 to 9 minutes, and the spin-drying process symbols M410 and M415 correspond to the execution time (spin-drying time) of the wash course of "soft" setting.

In this example, although the case where the corresponding spin-drying process symbol is set from the spin-drying process symbol group MB in accordance with the spin-drying time and the number of revolutions of the spin basket 6 during spin-drying has been described, the washing process symbol may be set in accordance with either the spin-drying time or the number of revolutions of the spin basket 6 during spin-drying.

As illustrated in fig. 6 (c), a drum drying process symbol group MC made up of a plurality of drum drying process symbols M320, M310, M300 corresponding to the symbol numbers 320, 310, 300 is stored in the memory 46a in correspondence with the drying process.

As for the contents of the drying stroke executed in the drying process, one or more drying process symbols corresponding to the mechanical force applied to the laundry accommodated in the rotary tub 6 by the stroke contents thereof are selected from the drum drying process symbol group MC, and the stroke contents thereof are stored in the memory 46a corresponding to the selected drum drying process symbols.

Drum drying process symbol M320 corresponds to the contents of the stroke in which the mechanical force applied to the laundry is stronger than drum drying process symbols M310 and M300, and corresponds to the contents of the stroke in which the mechanical force is faded out in the order of drum drying process symbols M320, M310 and M300. Further, a drum drying process symbol M300 is a symbol indicating that drum drying process is not possible.

For example, as shown in fig. 9, the "normal (weak)", "timed (30 minutes)" and "maintained" drying courses for performing the low temperature drying correspond to a drum drying process symbol M310, and the "normal (strong)", "fine" and "ironing" drying courses for performing the high temperature drying correspond to a drum drying process symbol M320.

The washing treatment symbol, the dehydrating treatment symbol, and the drying treatment symbol constituting the washing treatment symbol group, the dehydrating treatment symbol group, and the drying treatment symbol group may be all the symbols specified in JIS L0001: 2014, or may be some of them.

Next, a representative operation of the washing machine 1 having the above-described configuration will be described.

First, in an initial state at the time of power-on in which the power-on switch 26 is pressed, the control device 46 sets a predetermined stroke, and sets the content of the stroke executed in the set process as predetermined stroke content.

In this example, in an initial state immediately after the power is turned on, the control device 46 sets a "standard" course of the washing course, and displays the set course and the contents of the strokes of the respective processes executed in the course on the first display unit 41 (see fig. 3). In addition, the control device 46 acquires from the memory 46a an indication symbol corresponding to the travel content of the processing executed in the set travel (here, the "standard" travel) and an indication symbol corresponding to the travel content having a stronger operation strength than the travel content, and displays the acquired indication symbols on the second display unit 42.

Specifically, the control device 46 acquires two washing process symbols M141 and M131 corresponding to the stroke contents from the washing process symbol group corresponding to the washing process (washing stroke and rinsing stroke) as the indication symbols corresponding to the stroke contents of the washing stroke and rinsing stroke (stroke contents of the washing stroke: water flow "3", washing time "8 minutes", stroke contents of the rinsing stroke: water flow "3", and rinsing frequency "2") executed in the washing process of the "standard" of the washing course (see (c) of fig. 7).

Further, the control device 46 acquires two dewatering process symbols M440 and M445 (see fig. 8) corresponding to the stroke content from the dewatering process symbol group MB corresponding to the dewatering process as a symbol corresponding to the stroke content (the dewatering time is "7 minutes") of the dewatering stroke executed in the dewatering process of the "standard" course.

That is, when the "standard" course of the washing course is set, the control device 46 acquires the washing process symbols M141 and M131 and the dehydrating process symbols M440 and M445 from the memory 46a as the indication symbols corresponding to the course (see fig. 5).

Further, the control device 46 also obtains, from the set of washing process symbols and the set of dehydrating process symbols, an indication symbol corresponding to the contents of a stroke in which the mechanical force (load) applied to the laundry is greater and the operation strength is stronger than the contents of the stroke in the washing process and the dehydrating process performed in the "standard" course. In other words, the control device 46 also acquires, from the washing process symbol group and the dehydration process symbol group, the indication symbols indicating the process in which the mechanical force (load) applied to the laundry is greater than the indication symbols corresponding to the "standard" course, and here, the washing process symbols M140 and M130 (see fig. 5).

Then, the control device 46 displays the washing process symbols M140, M130, M141, and M131 and the dehydrating process symbols M440 and M445 acquired from the memory 46a on the second display portion 42 provided on the operation panel 25. In this example, as shown in fig. 3, the second display portion 42 is divided into a washing display area (first area) 42a in which a washing process symbol is displayed, a dehydrating process display area (second display area) 42b in which a dehydrating process symbol is displayed, and a tumble drying display area (third display area) 42c in which a tumble drying process symbol is displayed. The control device 46 displays the washing process symbols M140, M130, M141, and M131 among the acquired process symbols in the washing display area 42a, and displays the dehydration process symbols M440 and M445 in the dehydration process display area 42 b.

When the wash course select switch 29 is pressed and operated in the state of the "standard" course, the wash course is set in the order of "standard", "soak", "quick", "memory", "gentle", and "carpet" every time the operation is performed, and when the wash course select switch 29 is further operated from "carpet", the washing course returns to "standard".

In this way, each time the set course is changed by operating the wash course selection switch 29, the control device 46 acquires the indication symbol corresponding to the course set at that time and the indication symbol corresponding to the course content having stronger operation strength than the course content of the washing process and the spin-drying process executed in the course, and displays the acquired indication symbols on the second display unit 42 (see fig. 5). That is, every time the washing course is changed, the display is displayed on the second display portion 42, and the indication symbol is also changed.

When the washing operation setting switch 32, the rinsing operation setting switch 33, the dehydrating operation setting switch 34, the water flow setting switch 35, and the bath water switch 37 are operated in a state where any one of the washing courses is set, the intensity, the execution time, and the number of repetitions of the water flow in the washing course, the rinsing course, and the dehydrating course are changed, or the water supply source in the washing process is changed according to the operated switches, thereby changing the course contents of each course. The control device 46 acquires an indication symbol corresponding to the travel content set at that time and an indication symbol corresponding to the travel content having a stronger operation strength than the indication symbol every time the travel content is changed, and displays the acquired indication symbols on the second display unit 42.

When the water flow setting switch 35 is pressed in a state where the "standard" course of the washing course shown in fig. 3 is set, the water flow is sequentially changed and set between "1" and "5" while keeping the stroke contents other than the water flow unchanged. For example, when the setting of the water flow is changed from "3" to "5", the stroke content of the washing stroke is set to "5" and the washing time is "8 minutes", and the stroke content of the rinsing stroke is set to "5" and the number of times of rinsing is "2", the controller 46 changes the display of the water flow on the first display unit 41. The control device 46 also acquires the washing process symbols M140 and M130 corresponding to the travel contents. In this case, since there is no washing process symbol corresponding to the travel content having a stronger operation strength than the travel content, the washing process symbols M140 and M130 are displayed in the washing display area (first area) 42a (see fig. 10) of the second display unit 42. Further, even if the setting of the water flow is changed as described above, the contents of the dehydration process stroke are not changed, and therefore the dehydration process symbols M440 and M445 displayed when the "standard" course is set are continuously displayed in the dehydration process display area 42b of the second display unit 42.

When the bath water switch 37 is pressed, the water supply source in the washing process is switched between the tap water and the bath water while maintaining the water flow, the washing time, the rinsing frequency, and the dehydrating time in the dehydrating process. For example, in a state where the water flow of the "standard" course shown in fig. 11 is changed to "5", when the bath water is set as the water supply source in the washing process by operating the bath water switch 37, the controller 46 changes the display of the bath water on the first display unit 41. Assuming that there is a possibility that high-temperature water may be supplied to water tub 5 and a washing stroke and a rinsing stroke of the high-temperature water are executed, control device 46 also acquires a washing process symbol M140 as an indication symbol corresponding to the contents of the stroke. In this case, since there is no washing process symbol corresponding to the travel content having a stronger operation intensity than the travel content, the washing process symbol M140 is displayed in the washing display area (first display area) 42a (see fig. 11) of the second display unit 42. Further, since the contents of the dehydration process routine are not changed even if the water supply source in the washing process is changed as described above, the dehydration process symbols M440 and M445 displayed when the "standard" course is set are continuously displayed in the dehydration process display area 42b of the second display unit 42.

When the washing operation setting switch 32 is pressed in a state where the "standard" course of the washing course shown in fig. 3 is set, the water flow is set to "3" and only the course content of the washing course is performed, and further, the pressing operation of the washing operation setting switch 32 is repeated, thereby setting the execution time (washing time) of the washing course within a predetermined range (1 to 12 minutes).

For example, as shown in fig. 12, when the water flow is set to "3" and the washing time is set to "1 minute" as the stroke content of the washing stroke, and the rinsing stroke, the spin-drying stroke, and the drying stroke are not set, the control device 46 obtains, from the memory 46a, the washing process symbols M142 and M132 (see fig. 7 (c)) corresponding to the stroke content of the washing stroke, and the washing process symbols M140, M130, M141, and M131 corresponding to the stroke content having stronger operation strength than the stroke content. Then, the acquired washing process symbols M140, M130, M141, M131, M142, and M132 are displayed in the washing display area 42 a.

Further, when the rinsing operation setting switch 33 is pressed in a state where only the washing stroke is set as shown in fig. 12, the number of times of rinsing in the rinsing stroke is set within a predetermined range (1 to 4 times). For example, as shown in fig. 13, when the number of times of rinsing is set to 4, the control device 46 acquires, from the memory 46a, the washing process symbols M141 and M131 (see fig. 7 (c)) corresponding to the contents of the washing stroke and the rinsing stroke, and the washing process symbols M140 and M130 corresponding to the contents of the stroke having stronger operation strength than the contents of the stroke. Then, the acquired washing process symbols M140, 130, M141, and M131 are displayed in the washing display area 42 a.

In the present embodiment, the case where the washing process corresponds to the washing process symbol group MA, the dehydrating process corresponds to the dehydrating process symbol group MB, the drying process corresponds to the drying process symbol group MC, and one process corresponds to one process symbol group has been described, but one process may correspond to a plurality of process symbol groups.

For example, when the intermediate spin stroke for centrifugally spin-drying the laundry by rotating the rotary tub 6 at a high speed in one direction and the rinse stroke for supplying tap water or bath water into the water tub 5 and rotating the rotary tub 6 forward and backward at a low speed are executed in the rinse stroke of the washing process, and the washing stroke, the rinse stroke, and the spin stroke are executed in combination in the washing process, the indication symbol displayed on the second display unit 42 may be determined by associating the washing process with the washing process symbol group MA and the spin process symbol group MB, associating the washing process symbol with the stroke contents of the washing stroke and the rinse stroke performed in the washing process, and associating the spin process symbol with the stroke contents of the intermediate spin stroke and the spin stroke performed in the washing process.

In order to set a washing-drying course in an initial state where a "standard" course of the washing course is selected, the washing-drying course selection switch 30 is pressed. Then, the control device 46 sets a "standard" course of the washing course and a "standard (strong)" course of the drying course executed subsequent to the washing course. Then, as shown in fig. 14, the control device 46 displays the set course and the contents of the schedule of each process executed in the course on the first display unit 41. In addition, the display symbol corresponding to the course content of the processing executed in the set course (here, the "standard" course of the washing course and the "standard (strong)" course of the drying course) and the display symbol corresponding to the course content having stronger operation strength than the course content are acquired from the memory 46a, and the acquired display symbols are displayed on the second display unit 42.

Specifically, as described above, the control device 46 acquires the washing process symbols M141 and M131 and the spin-drying process symbols M440 and M445 from the memory 46a as the symbols corresponding to the "standard" course of the washing course, and also acquires the washing process symbols M140 and M130 (see fig. 5) indicating a process stronger than these symbols.

Further, control device 46 obtains drum drying process symbol M320 from the drying process symbol group corresponding to the drying process as an indication symbol corresponding to the "standard (strong)" course of the drying course. If there is an indication symbol indicating a stronger process than the acquired drum drying process symbol M320, the control device 46 also acquires the indication symbol, but since there is no drum drying process symbol corresponding to the stroke content having a stronger operation strength, only the drum drying process symbol M320 is acquired.

Then, as shown in fig. 14, the controller 46 causes the washing process symbols M140, M130, M141, and M131 among the acquired process symbols to be displayed in the washing display area 42a, causes the spin-drying process symbols M440 and M445 to be displayed in the spin-drying display area 42b, and causes the tumble drying process symbol M320 to be displayed in the tumble drying display area 42 c.

Then, when the washing/drying course selection switch 30 is pressed in a state in which the washing/drying course of the "standard" course and the "standard (strong)" course of the drying course are set, the setting of the drying course is changed from the "standard (strong)" to the "standard (weak)" while maintaining the "standard" course of the washing course. Accordingly, as shown in fig. 15, the display of the first display unit 41 indicating the contents of the routine of each process is changed, and the drum drying process symbol M310 corresponding to the "standard (weak)" of the drying course and the drum drying process symbol M320 corresponding to the process stronger than the symbol are displayed in the drum drying display area 42c of the second display unit 42. In addition, since the washing course is not changed in the above operation, the display of the washing display area 42a and the dehydrating process display area 42b of the second display unit 42 is not changed.

Further, when the washing and drying course select switch 30 is pressed, the drying course is set in the order of "normal (weak)", "fine", "ironing", "timing (30 minutes)", and "maintenance" every time the washing and drying course select switch 30 is operated, and when the washing and drying course select switch 30 is further operated from "maintenance", the drying course returns to "normal (strong)".

In this way, each time the set drying course is changed by operating the washing/drying course selection switch 30, the control device 46 acquires a drum drying process symbol corresponding to the course set at that time and an indication symbol corresponding to a course content having a stronger operation strength than the course content of the drying process executed in the course, displays the acquired indication symbols on the second display unit 42, and displays the drum drying process symbol on the drum drying display area 42 c.

In order to set the drying course in the initial state of the "standard" course in which the washing course is selected, the drying course select switch 31 needs to be pressed. Then, the control device 46 sets the "standard (strong)" course of the drying course. Then, as shown in fig. 16, the control device 46 displays the set course and the contents of the schedule of each process executed in the course on the first display unit 41. In addition, the control device 46 acquires the drum drying process symbol M320 corresponding to the course content of the drying process executed in the "standard (strong)" course of the drying course from the memory 46a, and if there is an indication symbol corresponding to the course content having stronger operation strength than the course content, the control device 46 acquires the indication symbol, but since there is no drum drying process symbol corresponding to the course content having stronger operation strength, the drum drying process symbol M320 is displayed in the drum drying display area 42c of the second display portion 42.

Further, when the drying course select switch 31 is pressed, the drying course is set in the order of "normal (strong)", "normal (weak)", "fine", "ironing", "timing (30 minutes)", and "maintenance" every time the drying course select switch is operated, and when the washing drying course select switch 30 is further operated from "maintenance", the drying course is returned to "normal (strong)".

In this way, each time the set drying course is changed by operating the drying course selection switch 31, the control device 46 acquires the drum drying process symbol corresponding to the course set at that time and the indication symbol corresponding to the course content having a stronger operation strength than the course content of the drying process executed in the course, displays the acquired indication symbols on the second display unit 42, and displays the drum drying process symbol on the drum drying display area 42 c.

After the process executed by washing machine 1 and the contents of the strokes executed in the respective processes are set, start of operation of washing machine 1 is started in accordance with the set contents of the strokes by pressing start switch 28.

The washing machine 1 according to the present embodiment described above can obtain the following effects. That is, in the washing machine 1 of the present embodiment, when the course contents to be performed in the washing process, the spin-drying process, and the drying process are set, the indication symbol corresponding to the set course contents is displayed on the second display unit 42, and therefore, by comparing the indication symbol attached to the laundry with the indication symbol displayed on the second display unit 42, the user can easily select the process and the course contents suitable for the laundry.

Since the control device 46 displays the indication symbol corresponding to the changed course content every time the course content is changed, the user can find the process suitable for the clothes and the course content while changing the course content of each process.

Further, since the second display unit 42 is divided into the washing display area 42a for displaying the washing process symbol, the dewatering process display area 42b for displaying the dewatering process symbol, and the drum drying display area 42c for displaying the drum drying process symbol, the display symbols can be arranged in units of each process and displayed on the second display unit 42, and the visibility is excellent.

In the present embodiment, since the control device 46 displays not only the indication symbol corresponding to the set travel contents to be processed on the second display unit 42 but also the indication symbol corresponding to the travel contents having a stronger operation strength than the travel contents on the second display unit 42, the user can be made aware that the laundry with the indication symbol corresponding to the travel contents having a stronger travel contents than the travel contents actually set on the washing machine 1 can be processed, and the types of the travel contents selectable by the user can be increased, thereby improving convenience.

(modification 1)

In the above-described embodiment, the description has been given of the case where the indication symbol corresponding to the set process is displayed on the second display unit 42 and the indication symbol corresponding to the unset process is not displayed on the second display unit 42, but for the unset process, all the indication symbols belonging to the indication symbol group corresponding to the process may be displayed on the second display unit 42 as the stroke content of the weakest operation strength with which the load is not applied to the laundry.

For example, when the washing process and the spin-drying process are set as in the washing course and the drying process is not set, the washing process symbol and the spin-drying process symbol corresponding to the course contents of the washing process and the spin-drying process symbol and the washing process symbol and the spin-drying process symbol corresponding to the course contents having stronger operation strength than the course contents may be displayed on the second display unit 42, and all the drying process symbols of the drum drying process symbol group MC corresponding to the drying process may be displayed on the second display unit 42.

In this case, the laundry which can be processed by the process set in the washing machine 1 and the contents of the course can be displayed in combination with the indication symbol attached to the laundry, and convenience can be improved.

(modification 2)

In the above-described embodiment, the description has been given of the case where the control device 46 displays the indication symbol corresponding to the travel content of the set process and the indication symbol corresponding to the travel content having the operation strength stronger than the travel content on the second display unit 42, but only the indication symbol corresponding to the travel content of the set process may be displayed on the second display unit 42 without displaying the indication symbol corresponding to the travel content having the operation strength stronger than the travel content.

(modification 3)

In the above-described embodiment, the case where the second display unit 42 displaying the indication symbol is provided on the operation panel 25 has been described, but may be displayed on a display terminal provided outside the washing machine 1, such as a mobile terminal.

(modification 4)

In the above-described embodiment, the case where the expression symbol specified in JIS L0001 is used as the expression symbol has been described, but the expression symbol may be based on other specifications such as JIS L0217. Alternatively, a switch or the like may be provided, and the symbols based on a plurality of specifications may be stored in the memory 46a in association with each other, and the symbols based on a plurality of different specifications may be displayed on the second display unit 42 in a switching manner by operating the switch or the like.
