Summary of the Invention

Problems to be Solved by the Invention

[0005] In particular, the drying cycle, including the drying process, takes significantly longer depending on the weight of the laundry. To avoid situations where the cycle is not completed by the scheduled end time, the configurable scheduled end time is often set to a time that is longer than the actual required cycle duration. As a result, even when scheduled operation should be possible, it may not be available, or users may not know how much laundry can be handled within the desired timeframe when using the scheduled operation.

[0006] Therefore, we provide a garment processing device that allows users to set an end time according to the amount of laundry, thereby improving user convenience. [Means for solving the problem]

[0007] The garment processing apparatus of the embodiment is capable of time-setting operation in which the end time of operation is set in advance and is executed, and comprises an operation unit that accepts the setting of the end time by the user, a display unit that displays information to the user, a control device that performs a capacity determination process to determine the upper limit of the amount of laundry that can be processed within the usable period which is the difference from the current time to the end time, and a process that displays the upper limit of the amount of laundry determined by the capacity determination process on the display unit.

[Modes for carrying out the invention]

[0009] Hereinafter, a clothing treatment apparatus according to a plurality of embodiments will be described referring to the drawings. The clothing treatment apparatus of these embodiments is a horizontal-axis or diagonal-axis drum-type washing machine having a drying function. Note that the clothing treatment apparatus of these embodiments can also be applied to a so-called fully automatic vertical-axis washing machine with or without a drying function. Furthermore, the clothing treatment apparatus of these embodiments can also be applied to a configuration without a washing function.

[0010] (First Embodiment) Referring to FIGS. 1 to 15, the first embodiment will be described. The washing and drying machine 10 shown in FIGS. 1 and 2 is an application example of the clothing treatment apparatus of this embodiment. The washing and drying machine 10 includes an outer box 11, a door 12, an outer tub 13, a rotary tub 14, a bellows 15, a rotary tub motor 16, a water supply mechanism 17, a drainage mechanism 18, an operation panel 19, an air duct 20, a drying unit 30, and a control device 40. In this embodiment, the side of the door 12 with respect to the outer box 11, that is, the left side of the paper surface of FIG. 1, is defined as the front side of the washing and drying machine 10. The outer box 11 is formed in a rectangular hollow box shape, for example, by a stainless steel plate or the like, and constitutes the outer shell of the washing and drying machine 10. The outer box 11 has an entrance / exit 111 at the front portion that communicates the inside of the outer tub 13 and the outside of the outer box 11. Further, the outer box 11 has an outer box exhaust port 112 at the back of the upper surface that communicates the inside of the outer tub 13 and the outside of the outer box 11.

[0011] The door 12 is provided at the front of the outer box 11 and is configured to be able to open and close the entrance / exit 111. The user can put laundry into or take out laundry from the rotary tub 14 through the entrance / exit 111 with the door 12 open.

[0012] The outer tub 13 is formed in a bottomed cylindrical shape having an opening 131 on the front side. In the case of this embodiment, the outer tub 13 can store water inside and functions as a water tank. The outer tub 13 has an air outlet 132, an air inlet 133, and a drain port 134. The air outlet 132 is formed, for example, at the upper part of the outer tub 13. In this embodiment, the air outlet 132 is at the upper front part of the peripheral wall constituting the cylindrical portion of the outer tub 13, and is provided at a position away from the top of the peripheral wall of the cylindrical portion of the outer tub 13 in the left-right direction, that is, at the center in the left-right direction of the outer tub 13. The air inlet 133 is formed, for example, at the bottom of the outer tub 13. In this embodiment, the air inlet 133 is provided at a position slightly above the center in the up-down direction of the bottom at the bottom of the outer tub 13. The drain port 134 is formed at the lower part of the outer tub 13. In this embodiment, the drain port 134 is formed at the lowermost part of the peripheral wall of the outer tub 13. The air outlet 132, the air inlet 133, and the drain port 134 communicate the inside and the outside of the outer tub 13 respectively.

[0013] The rotary tub 14 is formed in a bottomed cylindrical shape capable of accommodating laundry and is rotatably accommodated inside the outer tub 13. The rotation axis of the rotary tub 14 overlaps with the central axis of the outer tub 13. The rotary tub 14 has a plurality of communication holes 141. The communication holes 141 communicate the inside and the outside of the rotary tub 14. The communication holes 141 are formed over the entire peripheral wall constituting the cylindrical portion of the rotary tub 14 and the bottom of the rotary tub 14. The communication holes 141 mainly function as water passage holes through which water enters and exits during the washing operation and the dehydration operation, and function as ventilation holes through which air enters and exits during the drying operation and the removal operation. Also, although not shown in detail, a plurality of baffles are provided inside the peripheral wall of the rotary tub 14. The baffles stir the laundry accommodated inside the rotary tub 14.

[0014] The bellows 15 is provided around the entrance / exit 111 of the outer case 11 and the opening 131 of the outer tub 13. The bellows 15 is formed, for example, in a cylindrical bellows shape, and elastically connects the outer case 11 and the outer tub 13 in a state where the entrance / exit 111 and the opening 131 are in communication.

[0015] The rotary drum motor 16 is, for example, located on the outside of the bottom of the outer drum 13. The rotary drum motor 16 can be, for example, an outer rotor type direct drive motor. The shaft 161 of the rotary drum motor 16 penetrates the bottom of the outer drum 13 and protrudes inward from the outer drum 13, and is fixed to the bottom of the rotary drum 14. The rotary drum motor 16 rotates the rotary drum 14 relative to the outer drum 13. In this case, the shaft 161 of the rotary drum motor 16, the central axis of the outer drum 13, and the rotation axis of the rotary drum 14 are all aligned. In this specification, the rotational speed of the rotary drum 14 is equal to the rotational speed of the rotary drum motor 16.

[0016] The water supply mechanism 17 is a device for supplying water from an external water source, such as a water supply system, into the outer tank 13. The water supply mechanism 17 is installed, for example, inside the outer casing 11, above the outer tank 13, and more specifically, slightly to one side (left or right). The water supply mechanism 17 comprises a water supply valve 171, a water inlet case 172, and a water inlet pipe 173.

[0017] The water supply valve 171 is an electromagnetically driven on / off valve for liquids and is connected to an external water source, such as a water tap (not shown). The water filling case 172 is configured to accommodate laundry treatment agents such as detergent and finishing agents. The water filling pipe 173 connects the water supply valve 171 to the inside of the outer tub 13. The water supply valve 171 opens and closes the water filling path from the external water source to the outside tub 13 via the water supply mechanism 17. When the water supply valve 171 is opened, water from the external water source is poured into the outer tub 13 through the water filling pipe 173 and the water filling case 172. If laundry treatment agents are stored in the water filling case 172 at the time of pouring, the laundry treatment agents in the water filling case 172 are washed into the outer tub 13 along with the water flowing through the water filling case 172. Note that the washer-dryer 10 does not necessarily have to be equipped with a water filling case 172. That is, the washer-dryer 10 may be configured so that the user directly puts laundry treatment agents into the outer tub 13.

[0018] The drainage mechanism 18 has the function of discharging water stored inside the outer tub 13 to the outside of the washing and drying machine 10. The drainage mechanism 18 consists of a drain valve 181 and a drain pipe 182. The drain valve 181 is, for example, an electromagnetically driven on / off valve for liquids, and opens and closes the drainage path from inside the outer tub 13 to the outside of the machine via the drainage mechanism 18.

[0019] The control panel 19 has the function of an operating unit that receives operational input from the user regarding the settings and operation of the washer-dryer 10, and a display unit that presents information regarding the settings and operation of the washer-dryer 10 to the user through display, voice, etc. The control panel 19 can be configured as, for example, a touch panel display, or as touch switches or mechanical switches. Alternatively, the control panel 19 can be configured in combination with a touch panel display, touch switches, and mechanical switches. The control panel 19 is provided, for example, at the front of the top surface of the outer casing 11.

[0020] The air passage 20 connects the air outlet 132 and the air inlet 133 inside the outer casing 11 and outside the outer tank 13. As shown by arrow A in Figure 1, the air passage 20 takes in air from inside the outer tank 13 through the air outlet 132, turns it into warm air by passing it through the drying unit 30, and then supplies that warm air to the inside of the outer tank 13 through the air inlet 133.

[0021] As shown in Figure 2, the air passage 20 is configured to include, for example, an exhaust duct 21, a filter device 22, a connecting duct 23, a heat exchange unit 24, and a supply air duct 25. The exhaust duct 21, the filter device 22, the connecting duct 23, the heat exchange unit 24, and the supply air duct 25 are arranged in order along the airflow within the air passage 20.

[0022] The exhaust duct 21 is a duct that connects the air outlet 132 of the outer tank 13 to the filter device 22. The filter device 22 has a filter (not shown) inside that collects lint and foreign matter contained in the air flowing through the air passage 20. The connecting duct 23 is a duct that connects the filter device 22 to the heat exchange unit 24. The heat exchange unit 24 is located in the lower inside of the outer box 11 and below the outer tank 13 and the rotating tank 14. The air taken in from the outer tank 13 to the air passage 20 is dehumidified and heated as it passes through the heat exchange unit 24, becoming dry warm air. The supply air duct 25 is a duct that connects the heat exchange unit 24 to the air inlet 133 of the outer tank 13.

[0023] The air passage 20 has an air passage exhaust port 26. The air passage exhaust port 26 is an opening formed in the middle of the air passage 20, and connects the inside and outside of the air passage 20 with the outside of the machine. In this embodiment, the air passage exhaust port 26 is formed on the downstream side of the filter device 22 and the upstream side of the heat exchange unit 24, in this case the connecting duct 23. As shown in Figure 1, the air passage exhaust port 26 is in communication with the outer box exhaust port 112 formed in the outer box 11. As a result, the air passage exhaust port 26 connects the inside of the air passage 20 with the outside of the machine.

[0024] Furthermore, the air passage 20 is provided with a damper 27 that opens and closes the air passage exhaust port 26. The damper 27 is rotated by a damper motor 271 shown in Figure 4 to open and close the air passage exhaust port 26. By opening and closing the damper 27, as shown by arrow C in Figure 1, a portion of the air inside the air passage 20 can be discharged outside the air passage 20, in this case outside the outer casing 11.

[0025] The drying unit 30 is installed in the middle of the air passage 20 and generates hot air to dry the laundry contained in the rotating tub 14. The hot air generated by the drying unit 30 is supplied into the outer tub 13 by the blowing function of the blower 37. The drying unit 30 generates hot air. The blower 37 blows air into the drying unit 30 and supplies the hot air generated by the drying unit 30 into the outer tub 13 from the air inlet 133. The drying unit 30 can be configured to include, for example, a heat pump type or a heater type heating device. In this embodiment, the drying unit 30 is configured to include a heat pump type heating device and has an evaporator 31, a condenser 32, a compressor 33, a throttler 34, and a refrigerant pipe 35.

[0026] The evaporator 31 and condenser 32 are located within the heat exchange section 24. The evaporator 31 is positioned upstream of the condenser 32 in relation to the airflow within the heat exchange section 24 during drying operation. The evaporator 31 and condenser 32, together with the compressor 33 and throttle 34 located outside the heat exchange section 24, form a heat pump mechanism, or refrigeration cycle, cyclically connected by refrigerant pipes 35. Air passing through the heat exchange section 24 is cooled and dehumidified by the evaporator 31. The dehumidified air is then heated by the condenser 32 to become warm air.

[0027] The downstream side of the heat exchange unit 24 is connected to the air inlet 133 of the outer tub 13 by an air supply duct 25. The washing and drying machine 10 is equipped with a blower 37. The blower 37 is provided, for example, at the connection point between the heat exchange unit 24 and the air supply duct 25. The blower 37 draws in air from inside the heat exchange unit 24 and discharges it towards the air supply duct 25. As a result, the hot air that has been dehumidified and heated in the heat exchange unit 24 is supplied from the air inlet 133 into the outer tub 13 and further into the rotating tub 14 by the blowing action of the blower 37.

[0028] The blower 37 is installed in the middle of the air passage 20 and has the function of sending air from the air passage 20 to the outer tank 13 and the rotating tank 14, and drawing air from the outer tank 13 and the rotating tank 14 into the air passage 20. The blower 37 can be made up of, for example, a sirocco fan. The blower 37 is made up of a fan 371 and a fan motor 372.

[0029] The washer-dryer 10 has a washing function and a drying function. The washer-dryer 10 includes a control device 40, a weight detection unit 41, and a timing unit 42. The control device 40 is mainly composed of a microcomputer having a CPU 401 and a storage area 402 such as ROM, RAM, and non-volatile memory. The control device 40 has the function of managing the operation of the entire washer-dryer 10. The rotary drum motor 16, the water supply valve 171, the drain valve 181, the fan motor 372, and the drying unit 30 are electrically connected to the control device 40 and operate under the control of the control device 40. In this specification, when the control device 40 operates the drying unit 30, it means that the drying unit 30 is also driven as a heating device, and in this embodiment, this includes driving the compressor 33. Also, when the drying unit 30 is electrically connected to the control device 40, it means that the compressor 33 is electrically connected to the control device 40.

[0030] The control device 40 can selectively perform washing, drying, and washing-drying operations by operating the rotary drum motor 16, water supply valve 171, drain valve 181, fan motor 372, damper motor 271, and drying unit 30 as needed. In this embodiment, "operation" in washing, drying, washing-drying, and the removal operation described below refers to a course that performs one or more steps, and is an operational unit that the user can wash. The user can select and execute a desired operation from a course that includes washing, drying, washing-drying, and removal operations by operating the control panel or the like.

[0031] The weight detection unit 41 has the function of detecting the weight of laundry, such as clothes, contained in the rotating tub 14. The weight detection unit 41 can measure the load applied to the rotating tub motor 16 by, for example, measuring the current flowing to the rotating tub motor 16 when the rotating tub 14 is rotated, and can detect the weight of the laundry contained in the rotating tub 14 based on that load. Alternatively, the weight detection unit 41 can be implemented using, for example, an encoder that detects the rotation speed of the rotating tub motor 16. In this case, the weight detection unit 41 measures the load on the rotating tub motor 16 from the difference between the target rotation speed and the actual rotation speed, and detects the weight of the laundry based on that load.

[0032] The timing unit 42 has the function of measuring the current time and managing the duration of each process during operation and the waiting period during time-set operation. In this embodiment, the timing unit 42 is provided in the washing machine 10, but it is not limited to this. For example, in another embodiment, the washing machine 10 may be equipped with a communication unit that can communicate with an external server, and the time may be obtained from the external server by the communication unit, with the control device 40 managing the period.

[0033] The washing cycle is primarily for washing laundry and includes at least one of the following processes: washing, rinsing, and spinning. The drying cycle is primarily for drying wet laundry and includes a drying process. The wash-and-dry cycle is primarily for washing laundry and drying wet laundry and includes both the washing and drying cycles. The specific details of each cycle can be automatically adjusted or modified as appropriate based on the amount of laundry, the degree of soiling, and the condition of the laundry, or based on user input on the control panel.

[0034] The washing process involves rotating the rotating tub 14 with water stored in the outer tub 13, thereby agitating the laundry in the rotating tub 14 along with the water, and washing the laundry in this process. When the washing process is executed, the control device 40 closes the drain valve 181 and opens the water supply valve 171 to pour water into the outer tub 13. At this time, laundry treatment agents such as detergent that have been put into the water supply case 172 are poured into the outer tub 13 along with the water. The control device 40 further closes the water supply valve 171 and the drain valve 181 and rotates the rotating tub 14 by mainly operating the rotating tub motor 16 at a low speed, thereby beating and washing the laundry in the rotating tub 14. In the washing process, the control device 40 may also pour water by intermittently opening and closing the water supply valve 171, for example.

[0035] The dewatering process involves rotating the rotary tub 14 at high speed to centrifugal dewater wet laundry. When the dewatering process is executed, the control device 40 opens the drain valve 181 with the water supply valve 171 closed, thereby draining the water stored in the outer tub 13. The control device 40 also rotates the rotary tub 14 at high speed by operating the rotary tub motor 16 at high speed, thereby draining the water contained in the wet laundry stored in the rotary tub 14.

[0036] The rinsing process involves rinsing the laundry in the rotating tub 14 by operating the rotary tub motor 16 to open and close the rotating tub 14 while water is stored in the outer tub 13, thereby agitating the laundry with the water. When the rinsing process is executed, the control device 40, similar to the washing process, opens the water supply valve 171 with the drain valve 181 closed and pours water into the outer tub 13. At this time, laundry treatment agents such as finishing agents that have been put into the water supply case 172 are poured into the outer tub 13 along with the water. Subsequently, similar to the washing process, the control device 40 rinses the laundry in the rotating tub 14 by mainly operating the rotary tub motor 16 at a low speed, for example, with the water supply valve 171 and drain valve 181 closed. In the rinsing process, the control device 40 may also pour water by intermittently opening and closing the water supply valve 171, for example.

[0037] The drying process involves rotating the rotary tub 14 at a medium speed to agitate the laundry while operating the drying unit 30 and the blower 37 to blow warm air onto the laundry, thereby drying the laundry contained in the rotary tub 14. In the case of a wash-and-dry operation, the drying process is performed after the dewatering process. When the drying process is executed, the control device 40 rotates the rotary tub motor 16 at a medium speed with the water supply valve 171 and the drain valve 181 closed, and simultaneously operates the drying unit 30 and the blower 37.

[0038] The washer-dryer 10 can immediately execute an operation selected from the group including at least a washing operation, a drying operation, and a washer-drying operation, or it can be set to end after a predetermined period of time has elapsed. Executing an operation set to end after a predetermined period of time is called a time-scheduled operation. Depending on the current time and the end time of the time-scheduled operation, even in a time-scheduled operation, there may be no waiting time and the process may be executed immediately.

[0039] When the control device 40 is powered on, it displays a screen 100 on the operation panel 19, for example, as shown in Figure 4. The screen 100 is operated by the user to select an operation from wash operation, drying operation or wash operation, or to select an operation method for washing from immediate operation or time-set operation. The screen 100 has operation content keys 51 to 53 for selecting an operation content, an immediate operation start key 54, and setting method keys 55 to 56 for selecting a setting method for time-set operation. In this specification, operating a key means selecting an item corresponding to the target key, and includes concepts such as pressing a key and clicking a key.

[0040] The operation content key 51 is the key that the user operates when selecting a wash cycle. The operation content key 52 is the key that the user operates when selecting a dry cycle. The operation content key 53 is the key that the user operates when selecting a wash and dry cycle. Figure 4 shows the state in which the wash and dry cycle has been selected as the operation content by the user operating the operation content key 53.

[0041] The immediate start key 54 is a key to be operated when you want to start operation immediately. If the user wants to start operation immediately without using the scheduled operation, they can operate the immediate start key 54. When the immediate start key 54 is operated, the control device 40 immediately starts the operation selected by the operation content keys 51 to 53.

[0042] If the user does not want to start the operation immediately, but rather wants to end the operation after a predetermined period of time or at a predetermined time, they operate the setting method keys 55 and 56. Setting method key 55 is the key that the user operates when selecting the first setting method. Setting method key 56 is the key that the user operates when selecting the second setting method. The user can select the first or second setting method by operating the setting method key 55 or setting method key 56 while the user has selected an operation from washing, drying, or washing and drying.

[0043] The first setting method is a setting method that allows the end time of the time-setting operation to be set to a time after the current time has elapsed, based on the period required to perform each operation on the maximum capacity of laundry in the washer-dryer 10. In this case, the end time of the time-setting operation cannot be set to a time after the elapsed period has elapsed, regardless of the weight of the laundry contained in the rotating tub 14. Conversely, since the first setting method can be used to perform the setting operation without considering the actual weight of the laundry contained in the rotating tub 14, the number of times the user has to operate the control panel 19 can be reduced. In this embodiment, the first setting method is referred to as "easy reservation".

[0044] The second setting method is a setting method that allows the end time of the time-setting operation to be set to a period of time elapsed from the current time, based on the required period, which is the period of time required to perform each operation on the laundry contained in the rotating tub 14. In this case, the required period changes depending on the weight of the laundry contained in the rotating tub 14, and therefore the time that can be set as the end time of the time-setting operation also changes depending on the weight of the laundry contained in the rotating tub 14. In this embodiment, the second setting method is referred to as "precise reservation".

[0045] The screen 101 shown in Figure 5 is displayed on the operation panel 19 when the first setting method, i.e., "Easy Reservation," is selected on screen 100. Screen 101 consists of setting method keys 55 and 56, an information area 57, one or more time setting keys 581 and 582 (in this case, two), and a start key 59. In this case, since the first setting method is selected, the setting method key 55 is highlighted, while the setting method key 56 is not highlighted. The highlighting of the setting method key 55 may be done, for example, by displaying the setting method key 55 with higher brightness or larger size than the setting method key 56.

[0046] Information area 57 displays information about the first setting method. Users can view information area 57 to obtain information about the first setting method. For example, Figure 5 shows that information area 57 displays the description of the first setting method as "You can easily start scheduled operation with a small number of operations."

[0047] The time setting keys 581 and 582 are keys that the user operates when setting and inputting the end time of the operation. In this case, the user can set the "hour" of the end time by operating the time setting key 581, and the user can set the "minute" of the end time by operating the time setting key 582. In this case, the control device 40 limits the end time that can be set by operating the time setting keys 581 and 582 to a time after the elapsed period from the current time. The standard period is predetermined according to the operation content and is stored in the memory area 402. For example, in a normal wash and dry operation, the standard period is set to 7 hours. In this embodiment, the end time of the operation is set directly, but in other embodiments, the configuration may be such that the available period, which is the elapsed time from the present, is set.

[0048] The operation start key 59 is a key that the user operates when they have finished setting up the scheduled operation. When the operation start key 59 is operated, the waiting period for the scheduled operation begins. When the operation start key 59 is operated, the control device 40 calculates the waiting period from the current time measured by the timing unit 42, the end time, and the required period. In other words, the waiting period is the difference between the available period and the required period. When the operation start key 59 is operated, the timing unit 42 starts counting the waiting period set by the control device 40. When the waiting period has elapsed, the control device 40 executes the operation.

[0049] The screen 102 shown in Figure 6 is displayed on the operation panel 19 when the second setting method, i.e., "precise reservation," is selected on screen 100. Screen 102 consists of setting method keys 55 and 56, time setting keys 581 and 582, information areas 60 and 61, and a metering key 62. In screen 102, since the second setting method is selected, the setting method key 56 is highlighted compared to the setting method key 55.

[0050] Information areas 60 and 61 are areas that display information related to the second setting method. Information area 60 is displayed near the setting method keys 55 and 56. In this embodiment, information area 60 is displayed on screen 102, below the setting method keys 55 and 56. Information area 60 may display, for example, a description of the second setting method, in this case "Perfect Reservation". In the example shown in Figure 6, information area 60 displays the message, "We offer various suggestions to complete the operation within the set time and to do laundry better."

[0051] The information area 61 is displayed near the time setting keys 581 and 582. In this embodiment, the information area 61 is displayed on screen 102, below the time setting keys 581 and 582. The information area 61 displays information about the weight of laundry that can be processed by the end time, calculated based on the end time set by the user using the time setting keys 581 and 582 and the operation content selected on screen 100. The information about the weight of laundry that can be processed by the end time may include not only the weight of the laundry itself, but also examples of the type and number of laundry items that make up that weight. For example, in the example shown in Figure 6, the information area 61 displays, "To complete the operation by this time, the amount of laundry must be 3.4 kg or less (about 17 shirts)."

[0052] The control device 40 performs a process to determine the difference between the end time set by the user using the time setting keys 581 and 582 and the current time, that is, the available period that can be used for scheduled operation. Then, based on a chart pre-stored in the memory area 402, for example, shown in Figure 7, it performs a process to determine the weight of laundry that can be processed by the end time. The chart shown in Figure 7 shows an example of the weight of clothes placed in the rotating tub 14 and the required period, which is the period required until the end of the operation, when performing a wash and dry operation. In this embodiment, the weight of the laundry is classified into 0.4 kg or less, 0.5 kg to 0.9 kg, 1.0 kg to 1.4 kg, 1.5 kg to 1.9 kg, 2.0 kg to 2.4 kg, 2.5 kg to 2.9 kg, 3.0 kg to 3.4 kg, 3.5 kg to 3.9 kg, 4.0 kg to 4.4 kg, 4.5 kg to 4.9 kg, 5.0 kg to 5.4 kg, 5.5 kg to 5.9 kg, and 6.0 kg or more, and the required period is determined for each. The required time is set within a range, for example, from 1 hour and 40 minutes to 4 hours and 35 minutes, and the less weight the laundry, the shorter the required time.

[0053] Before starting the scheduled operation, the user can check the display in the information area 61 to determine whether the amount of laundry to be placed in the rotating tub 14 is appropriate in light of the set completion time. They may then increase or decrease the amount of laundry in the rotating tub 14 as needed.

[0054] The weighing key 62 is operated when the weight detection unit 41 detects the weight of the laundry contained in the rotating tub 14. The user operates the weighing key 62 with or without increasing or decreasing the amount of laundry in the rotating tub 14. When the weighing key 62 is operated, the control device 40 causes the weight detection unit 41 to detect the weight of the laundry contained in the rotating tub 14.

[0055] When the weight detection unit 41 detects the weight of the laundry, the control device 40 executes a determination process. The determination process determines whether the operation can be completed by the operation end time, based on the weight of the laundry detected by the weight detection unit 41, the operation content set by operating the operation content keys 51, 52, and 53, and the end time set by operating the time setting keys 581 and 582. More specifically, the determination process compares the available period with the required period. In this case, if the control device 40 determines that the available period is shorter than the required period, it prevents the execution of the time-set operation. The control device 40 disables the operation start key 59. For example, the control device 40 does not display the operation start key 59 on the screen. This prevents the user from completing the operation by the desired end time, thus avoiding situations where the user fails to meet the end time.

[0056] The screen 103 shown in Figure 8 is displayed on the operation panel 19 when the control device 40 determines that the available period is shorter than the required period. The screen 103 consists of a time display area 63, an information area 64, a detailed information acquisition key 65, a back key 66, and a metering key 62. As described above, since the available period is shorter than the required period, the operation start key 59 is not displayed on the screen 103.

[0057] The time display area 63 displays the end time set by the user using the time setting keys 581 and 582 on the screen 102. In this embodiment, the end time cannot be changed by operating the time display area 63, but in other embodiments, the time display area 63 may also function as the end time setting keys, allowing the end time to be changed.

[0058] The information area 64 can display the results of the judgment process. Furthermore, the information area 64 can display methods for improving the results of the judgment. In the example shown in Figure 8, it states, "The scheduled operation cannot be started because there is too much laundry. You can start the operation by reducing the amount by about 1.0 kg (about 5 shirts)."

[0059] In Figure 8, the detailed information acquisition key 65, labeled "Hint," is a key that the user operates when they want to obtain detailed information about how to improve the judgment result. The user can operate the detailed information acquisition key 65 if they want to know in detail how much the amount of laundry needs to be reduced before the machine can start.

[0060] When the detailed information acquisition key 65 is operated, the control device 40 displays, for example, the screen 104 shown in Figure 9 on the operation panel 19. Screen 104 consists of a detailed information area 67 and a close key 68. The detailed information area 67 displays more detailed information than the information area 64 regarding how much the amount of laundry needs to be reduced before the operation can start. For example, in the example shown in Figure 9, it states, "To reduce the amount of laundry by 1.0 kg, reduce the following amounts: 5 shirts, 2 sheets, 2-3 skirts, 2-3 pairs of cotton trousers, 3-4 bath towels, 14 face towels, and 8 long-sleeved undershirts." The close key 68 is operated to close the detailed information area 67 and return to screen 103.

[0061] Returning to screen 103, the back key 66 is used to return to screen 101. For example, if the user wants to change the end time of the operation, they will use the back key 66 to return to screen 101.

[0062] Furthermore, after reducing the amount of laundry according to the improvement advice in the information area 64, the user closes the door 12 and operates the weighing key 62. This causes the weight of the reduced laundry to be detected again by the weight detection unit 41. The control device 40 then performs the determination process again based on the detection result of the weight detection unit 41.

[0063] The screen 105 shown in Figure 10 is displayed on the operation panel 19 when the available period and the required period match as a result of the judgment process. The screen 105 consists of an operation start key 59, a metering key 62, a time display area 63, a back key 66, and an information area 69. The information area 69 can display the result of the judgment process. In this case, the information area 69 displays "The scheduled operation can be executed by the set time." Since the available period matches the required period and the time-setting operation can be completed by the end time, the control device 40 displays the operation start key 59 on the screen 105.

[0064] The screen 106 shown in Figure 11 is displayed on the operation panel 19 when the control device 40 determines that the available period is longer than the required period. The screen 106 consists of an operation start key 59, a metering key 62, a time display area 63, a back key 66, an information area 70, a detailed information acquisition key 71, and a setting key 72. Since the available period is shorter than the required period and the time setting operation can be completed by the end time, the control device 40 displays the operation start key 59 on the screen 106.

[0065] The information area 70 can display the results of the judgment process. Furthermore, the information area 70 can display advice regarding the judgment results. In the example shown in Figure 11, it states, "Since the amount of laundry is small, you can add more laundry or select a more thorough wash course. You can add about 1.2 kg more (about 6 shirts)."

[0066] In Figure 11, the detailed information acquisition key 71, labeled "Hint," is a key that the user operates when they want to obtain advice based on the judgment result. The user can operate the detailed information acquisition key 71 if they want to know in detail how much they can increase the amount of laundry.

[0067] When the detailed information acquisition key 71 is operated, the control device 40 displays, for example, the screen 107 shown in Figure 12 on the operation panel 19. Screen 107 consists of a detailed information area 73 and a close key 74. The detailed information area 73 displays more detailed information than the information area 70 on screen 106 regarding how much the amount of laundry can be increased. For example, in the example shown in Figure 12, it states, "1.2 kg of laundry corresponds to the following amounts: 6 shirts, 2 sheets, 3 skirts, 3 pairs of cotton trousers, 4 bath towels, 17 face towels, and 9 long-sleeved undershirts." The close key 74 is operated to close the detailed information area 73 and return to screen 106.

[0068] Returning to screen 106, the setting key 72, which displays "Thorough Wash Setting," is the key used to set the operating settings. For example, the user operates the setting key 72 if they want to wash their laundry more thoroughly, following the advice displayed in the information area 70.

[0069] When the setting key 72 is operated on screen 106, the control device 40 displays screen 108 on the operation panel 19. Screen 108 is a screen on which the details of the washing process, rinsing process, and spin-drying process can be set. Screen 108 is composed of, for example, process setting keys 75 to 80 and a back key 81.

[0070] The process setting keys 75-80 are used when you want to wash your laundry more thoroughly, even if it takes a little longer, or when you want to add a process to keep the inside of the washer-dryer 10 clean. For example, process setting key 75, labeled "Wash," allows you to set the duration of the washing process. Process setting key 76, labeled "Rinse," allows you to set the number of rinse cycles. Process setting key 77, labeled "Spin Dry," allows you to set the duration of the spin dry process. By operating process setting key 78, labeled "Automatic Cleaning," you can add an automatic cleaning process to clean the outer tub 13 between the rinse and spin dry processes. By operating process setting key 79, labeled "Mold Protect," you can add a drying process for the outer tub 13 and the rotating tub 14 after the set operation is complete and the user has removed the laundry. By operating process setting key 80, labeled "Change Rinse Control," you can select whether the rinse process is a shower rinse, a tub rinse, or a continuous water rinse.

[0071] The back key 81 is used by the user to return to screen 106 shown in Figure 11, either after or without using the process setting keys 75-80.

[0072] Next, the processing of the control device 40 in the case of time-set operation will be explained with reference to the flowcharts shown in Figures 14 and 15. At the start of Figure 14, it is assumed that the user has selected one of the following: washing operation, drying operation, or washing and drying operation, and that either the first setting method or the second setting method has been selected.

[0073] When time setting operation is selected (start), the control device 40 determines whether the setting method selected in step S11 is the second setting method. If the selected setting method is the first setting method (No in step S11), the control device 40 proceeds to step S12. In step S12, the control device 40 sets the time that can be set with the time setting keys 581 and 582 to a time after the reference period has elapsed from the current time measured by the timing unit 42.

[0074] Next, in step S13, the control device 40 determines whether the user has operated the time setting keys 581 and 582. If the user has not operated the time setting keys 581 and 582 (No in step S13), the control device 40 repeats the process in step S13. If the user has operated the time setting keys 581 and 582 (Yes in step S13), the control device 40 proceeds to step S14. In step S14, the control device 40 determines whether the operation start key 59 has been operated. If the operation start key 59 has not been operated (No in step S14), the control device 40 returns to step S13. If the operation start key 59 has been operated (Yes in step S14), the control device 40 proceeds to step S22.

[0075] If the selected setting method is the second setting method (Yes in step S11), the control device 40 proceeds to step S15. In step S15, the control device sets the time that can be set using the time setting keys 581 and 582 to the desired time.

[0076] Next, in step S16, the control device 40 determines whether or not the user has operated the time setting keys 581 and 582. If the time setting keys 581 and 582 have not been operated (No in step S16), the control device 40 repeats the process in step S16. If the time setting keys 581 and 582 have been operated (Yes in step S16), the control device 40 proceeds to step S17.

[0077] In step S17, the control device 40 obtains the available period from the end time set by operating the time setting keys 581 and 582 and the current time measured by the timing unit 42. In step S18, the control device 40 performs a capacity determination process to obtain the upper limit of the weight of laundry that can be processed by the end time, based on the available period obtained in step S17. Furthermore, in step S19, the control device 40 displays the upper limit of weight obtained in the capacity determination process on the screen 102 as shown in Figure 6.

[0078] In step S20, the control device 40 determines whether the user has instructed weight detection. In this case, the control device 40 determines whether the weighing key 62 has been operated. If weight detection is not instructed (No in step S20), the control device 40 repeats the process in step S20. If weight detection is instructed (Yes in step S20), the control device 40 proceeds to step S21. In step S21, the control device 40 causes the weight detection unit 41 to detect the weight of the laundry contained inside the rotating tub 14.

[0079] Next, in step S22, the control device 40 executes a determination process, the details of which are shown in Figure 15. Once the determination process begins, in step S31, the control device 40 obtains the required period based on the detection result of the weight detection unit 41. Subsequently, in step S32, the length of the available period and the required period are compared.

[0080] If the control device 40 determines that the available period is longer than the required period (in step S32, available period > required period), it proceeds to step S33. In step S33, the control device 40 displays the determination result and advice in the information area 70 of the screen 106. After that, the control device 40 proceeds to step S38.

[0081] If the control device 40 determines that the available period is shorter than the required period (in step S32, available period < required period), the control device 40 proceeds to step S34. In step S34, the control device 40 disables the operation start key 59. In step S35, the control device 40 displays the determination result and methods for improving the determination result on screen 108.

[0082] In step S36, the control device 40 determines whether or not there has been an instruction to detect weight. If there has been no instruction to detect weight (No in step S36), the control device 40 repeats the process in step S36. If there has been an instruction to detect weight (Yes in step S36), the control device 40 proceeds to step S37. In step S37, the control device 40 causes the weight detection unit 41 to detect the weight of the laundry contained inside the rotating tub 14. After that, the control device 40 proceeds to step S31.

[0083] If the control device 40 determines that the available period matches the required period (in step S32, available period = required period), the control device 40 proceeds to step S38. In step S38, the control device 40 determines whether the settings have been changed. Specifically, the control device 40 determines whether process setting keys 75 to 80 have been operated. If the settings have been changed (Yes in step S38), the control device 40 proceeds to step S31. If the settings have not been changed (No in step S38), the control device 40 proceeds to step S39.

[0084] In step S39, the control device 40 determines whether or not there has been an instruction to detect weight. If weight detection is instructed (Yes in step S39), the control device 40 proceeds to step S37. If weight detection is not instructed (No in step S39), the control device 40 proceeds to step S40.

[0085] In step S40, the control device 40 determines whether or not the operation start key 59 has been operated. If the operation start key 59 has not been operated (No in step S40), the control device 40 returns to step S38. If the operation start key 59 has been operated (Yes in step S40), the control device 40 terminates the determination process (returns).

[0086] Returning to the flowchart in Figure 14, the control device 40 obtains the standby period in step S23. The standby period is calculated from the difference between the available period and the required period. In step S24, the control device 40 determines whether the standby period managed by the timing unit 42 has elapsed since the operation of the start key 59. If the standby period has not elapsed (No in step S24), the control device 40 repeats the process in step S24. If the standby period has elapsed (Yes in step S24), the control device 40 proceeds to step S25.

[0087] In step S25, the control device 40 executes the set operation. This executes an operation selected from the group including washing, drying, or washing and drying, and completes by the end time (end). In this way, the control device 40 executes the processing in the time-setting operation.

[0088] According to the embodiment described above, the washing machine 10 as a clothing processing device is capable of time-setting operation, where the end time of the operation is set in advance and executed. The washing machine 10 comprises an operation panel 19 as an operation unit and a display unit, and a control device 40. The operation panel 19 as an operation unit has the function of accepting the user's setting of the end time. The operation panel 19 as a display unit has the function of displaying information to the user. The control device 40 performs a capacity determination process to determine the upper limit of the amount of laundry that can be processed within the available period, which is the difference from the current time to the end time, and a process to display the upper limit of the amount of laundry determined by the capacity determination process on the display unit.

[0089] The system displays an estimated weight of laundry that can be loaded to complete the scheduled cycle by the user's desired completion time, allowing users to load an appropriate amount of laundry and set the scheduled cycle accordingly. This provides a laundry processing device that allows for scheduling based on the amount of laundry, improving user convenience.

[0090] The washing machine 10 includes a rotating tub 14 and a weight detection unit 41. The weight detection unit 41 has the function of detecting the weight of the laundry contained inside the rotating tub 14. The control device 40 performs a process to determine the required period, which is the period required for operation, based on the detection result of the weight detection unit 41. The control device 40 compares the available period with the required period, and if the available period is shorter than the required period, it performs a process to display a suggestion to reduce the amount of laundry on the display unit.

[0091] For users, there is a need to have at least some of their laundry washed by a desired time, provided that the operation can be completed by that time. Therefore, instead of simply disabling scheduled operation when the required period is shorter than the usage period, the system offers more options for the user by suggesting a reduction in the amount of laundry loaded. This provides a garment processing device that improves user convenience.

[0092] The control panel 19, which serves as the operating unit, has an operation start key 59 for initiating operation. The control device 40 compares the available period with the required period, and if the available period is shorter than the required period, it disables the operation start key 59.

[0093] This helps to prevent situations where operations are not completed by the scheduled end time.

[0094] The washing machine 10 includes a rotating tub 14 and a weight detection unit 41. The weight detection unit 41 has the function of detecting the weight of the laundry contained inside the rotating tub 14. The control device 40 performs a process to determine the required period, which is the period required for operation, based on the detection result of the weight detection unit 41. The control device 40 compares the available period with the required period, and if the available period is longer than the required period, it performs a process to display on the display unit that it is possible to increase the amount of laundry or change the operation content.

[0095] If a user has initially loaded a small amount of laundry, they may want to add more if it can be processed by the desired completion time. Furthermore, even if a user has set a shorter cycle, they may want a more thorough wash if it can be processed by the desired completion time. By addressing these needs, a garment processing device that improves user convenience can be provided.

[0096] Selecting the second setting method allows for more precise time settings that match the actual weight of the laundry, but it also increases the number of operations the user needs to perform.

[0097] The washing and drying machine 10, as a garment processing device, is configured to allow the user to select whether or not to use a second setting method that enables setting the completion time to reflect the weight of the laundry contained in the rotating tub 14.

[0098] According to this, when scheduling operation, if precise time settings are not required, the first setting method, which requires fewer operations, can be selected in addition to the second setting method. This will provide a garment processing device that improves user convenience.

[0099] (Second Embodiment) Next, a second embodiment will be described with reference to Figures 16 to 20. In the second embodiment, the control device 40 automatically causes the weight detection unit 41 to detect the weight after the user has increased or decreased the amount of laundry in the rotating tub 14, without requiring the user to instruct weight detection.

[0100] As shown in Figure 16, the washing machine 10 is equipped with a door detection unit 43 that detects the open / closed state of the door 12. After the weighing key 62 has been operated once and the required period has been calculated, the control device 40, when the door detection unit 43 detects that the door 12 has opened once and then closed again, automatically causes the weight detection unit 41 to detect the weight of the laundry contained inside the rotating tub 14.

[0101] In this case, the control device 40 displays screens 103a, 105a, and 106a shown in Figures 17-19 on the operation panel 19, instead of screens 103, 105, and 106 of the first embodiment. The weighing key 62 is not displayed on screens 103a, 105a, and 106a.

[0102] Furthermore, the control device 40 executes the determination process shown in Figure 20 instead of the determination process shown in Figure 15 of the first embodiment. In this case, the control device 40 executes step S51 instead of step S36 of the first embodiment, and step S52 instead of step S39.

[0103] In step S51, the control device 40 determines whether the door detection unit 43 has detected the opening or closing of the door. If the opening or closing of the door has not been detected (No in step S51), the control device 40 repeats the process in step S51. If the opening or closing of the door has been detected (Yes in step S51), the control device 40 proceeds to step S37.

[0104] In step S52, the control device 40 determines whether the door detection unit 43 has detected the opening or closing of the door. If the opening or closing of the door is detected (Yes in step S52), the control device 40 proceeds to step S37. If the opening or closing of the door is not detected (No in step S52), the control device 40 proceeds to step S40. The control device 40 performs the processing in the time setting operation by executing the other processes in the same manner as in the flowchart of the first embodiment.

[0105] In this embodiment as well, the same effects as in the first embodiment described above are achieved.

[0106] The washing and drying machine 10, as a garment processing device, includes an entrance / exit 111, a door 12, and a door detection unit 43. The entrance / exit 111 allows laundry to be loaded into the rotating tub 14. The door 12 opens and closes the entrance / exit 111. The door detection unit 43 has the function of detecting the open or closed state of the door 12. After the control device 40 has performed a process to determine the required period, if the door detection unit 43 detects that the door 12 has moved from an open state to a closed state, it performs a process to cause the weight detection unit 41 to detect the weight of the laundry contained in the rotating tub 14.

[0107] When door 12 is opened or closed, it is assumed that the user has put laundry in or taken out. Therefore, as the weight of the laundry changes, the required time may also change. According to this embodiment, the weight is automatically detected again without the user having to operate the control unit. This provides a clothing processing device that improves user convenience.

[0108] Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of symbols]
