[0011] (Embodiment 1) A washing machine according to a first embodiment of the present disclosure will be described.

[0012] [Overall configuration] Fig. 1 is a schematic cross-sectional view showing a washing machine 1 according to a first embodiment of the present disclosure. As shown in Fig. 1, the washing machine 1 includes a housing 2, an outer tub 3, a washing tub 4, a drive unit 5, an automatic dosing unit 6, a manual dosing case 7, a connection flow path 8, a water supply device 10, a drain valve 11, a control unit 12, a storage unit 13, and an operation display unit 14.

[0013] <Case> The housing 2 is a member that forms the external appearance of the washing machine 1. An opening 20 and a door 21 that covers the opening 20 and can be opened and closed freely are provided on the front surface of the housing 2.

[0014] <Outer tank> The outer tub 3 is provided inside the housing 2 and is a roughly cylindrical member having the function of storing wash water. The outer tub 3 may be referred to as a water tub. The outer tub 3 has a tubular portion 34 and a bottom portion 36 that closes one end of the tubular portion 34. The central axis V0 of the outer tub 3 passes through the center of the bottom portion 36. The central axis V0 is inclined with respect to the horizontal. The outer tub 3 has an opening 31 at a position facing the opening 20 of the housing 2. The edge of the opening 31 is connected to the opening 20 of the housing 2 by a bellows 32 in a sealed manner. The outer tub 3 is provided with openings 33 and 35 for passing water. The opening 33 is an opening connected to the connection flow path 8, and the opening 35 is a drain port for draining the water in the outer tub 3 to the outside.

[0015] <Washing tub> The washing tub 4 is a generally cylindrical member that is rotatably provided around a central axis V0 inside the outer tub 3 and that contains laundry 15 such as clothes. The washing tub 4 may also be called an inner tub, a storage tub, or a drum. The washing tub 4 is formed with a large number of through holes 40. The through holes 40 communicate the washing tub 4 and the outer tub 3, allowing the movement of washing water between the washing tub 4 and the outer tub 3. The washing tub 4 has an opening 41 at a position facing the opening 20 of the housing 2 and the opening 31 of the outer tub 3. When the user of the washing machine 1 opens the door 21, the user can put laundry 15 into the washing tub 4 through the openings 20, 31, and 41.

[0016] <Drive unit> The driving unit 5 is a member that rotates the washing tub 4 around the central axis V0. The driving unit 5 has, for example, a motor that rotates the washing tub 4.

[0017] <Automatic insertion unit> The automatic dosing unit 6 is a device that automatically supplies a predetermined amount of agent from a tank that stores enough agent for multiple uses to the outer tub 3. The predetermined amount of agent is an appropriate amount and type of agent determined by the control unit 12 according to, for example, the contents of the operation course and the amount of laundry 15. The automatic dosing unit 6 is connected to the outer tub 3 via a connecting flow path 8.

[0018] In this specification, the agent includes liquid agents, powder agents, tablets, etc. used for treating laundry 15 such as clothes and towels, and may be contained in the tank in a water-soluble bag or pack. The agent includes detergent, fabric softener, neutral detergent, bleach, disinfectant, deodorizer, fragrance, laundry starch, and other laundry auxiliary agents. In the first embodiment, an example in which the agent is a liquid agent will be described.

[0019] The automatic dispensing unit 6 includes a case 61, tanks 62A, 62B, and 62C (tanks 62B and 62C are not shown), pump mechanisms 63A, 63B, and 63C (pump mechanisms 63B and 63C are not shown), and a developer discharge flow path 64.

[0020] In the first embodiment, tanks 62A and 62B contain predetermined types of agents. Specifically, tank 62A contains detergent, and tank 62B contains fabric softener. Tank 62C contains an agent of a type arbitrarily selected by the user. The user selects bleach or delicate detergent and pours it into tank 62C.

[0021] <Manual input case> The manual dispenser case 7 is a container for the user to manually dispense one dose of agent each time the washing machine 1 is operated. The manually dispensed agent is supplied to the outer tub 3 in the dispensed amount.

[0022] <Connection flow path> The connection flow path 8 is a flow path that connects the automatic feeding unit 6 and the manual feeding case 7 to the outer tub 3. Therefore, the water and agent flow from the automatic feeding unit 6 or the manual feeding case 7 into the outer tub 3 through the connection flow path 8. The connection flow path 8 extends downward from the automatic feeding unit 6 and the manual feeding case 7 to the opening 33 of the outer tub 3.

[0023] <Water supply device> The water supply device 10 is an openable and closable valve connected to a water faucet via an external hose, and when opened, supplies water to the outer tub 3. The water supply device 10 is provided on the upper part of the housing 2.

[0024] <Drain valve> The drain valve 11 is configured to be openable and closable, and when opened, allows the water stored in the outer tub 3 to be drained through an opening 35 of the outer tub 3. The drain valve 11 is provided in the lower part of the housing 2.

[0025] <Operation display section> Operation display unit 14 is a device for allowing the user to operate washing machine 1 and displaying various information to the user. Operation display unit 14 has an operation unit operated by the user and a display unit that displays various information such as images and text to the user. In the first embodiment, operation display unit 14 has a liquid crystal touch panel that integrally has an operation unit and a display unit. Operation display unit 14 is provided on the front surface of housing 2 at a position that can be operated and viewed by the user.

[0026] The operation display unit 14 is capable of displaying various screens. The operation display unit 14 can change the screen to be displayed in response to a user's operation. The user can input information by operating (for example, pressing) the display on each screen.

[0027] The operation display unit 14 can accept settings for an operation course in response to a user's operation. The operation display unit 14 can further accept settings related to automatic dispensing of the agents contained in the tanks 62A-62C in response to a user's operation. In other words, the user inputs settings for an operation course and settings related to automatic dispensing of the agents to the operation display unit 14. The operation display unit 14 accepts the user's input.

[0028] For example, the operation display unit 14 can receive settings for the type of drug, the reference amount of drug, and drug supply settings as information related to the automatic supply of drug.

[0029] In setting the type of agent, operation and display unit 14 accepts the setting of the type of agent in tank 62C. Since the types of agents contained in tanks 62A and 62B are fixed, setting of the types of agents in tanks 62A and 62B is omitted. In the first embodiment, operation and display unit 14 accepts "bleach" or "delicates detergent" as the type of agent in tank 62C.

[0030] In setting the reference amount of agent, the operation display unit 14 accepts the amount of agent dispensed per unit amount of water in the tanks 62A to 62C as the reference amount. In the first embodiment, the reference amount is a numerical value of the amount of agent dispensed per predetermined amount of water (for example, 30 L).

[0031] As the agent supply setting, the operation display unit 14 accepts a setting for whether or not the agent contained in the tanks 62A to 62C is automatically supplied (setting for whether or not the agent is supplied), and an adjustment amount for adjusting the agent supply amount relative to a reference amount. In the first embodiment, the operation display unit 14 accepts any of "more", "standard", "less", and "none" as the agent supply setting.

[0032] In setting whether or not to automatically add the agent, the operation display unit 14 accepts a setting of "Yes" or "No" as whether or not to automatically add the agent to the tanks 62A to 62C. When the "Yes" setting is accepted as whether or not to automatically add the agent, automatic addition of the liquid agent by the pump mechanisms 63A to 63C is executed in a certain operation course, and when the "No" setting is accepted, automatic addition of the liquid agent by the pump mechanisms 63A to 63C is not executed. The operation display unit 14 directly accepts the "No" setting in response to a user's operation, and indirectly accepts the "Yes" setting in response to a user's operation. Specifically, when the "Low", "Standard", or "More" setting is accepted as the adjustment amount of the agent in the tanks 62A to 62C, the operation display unit 14 accepts the "Yes" setting as whether or not to automatically add the agent to the tanks 62A to 62C.

[0033] In setting the adjustment amount of the agent, the operation display unit 14 accepts the setting of the adjustment amount of the agent in the tanks 62A to 62C. In the first embodiment, the operation display unit 14 accepts the setting of "less", "normal", or "more" as the adjustment amount of the agent in the tanks 62A to 62C. In the first embodiment, each of the settings of "less", "normal", and "more" corresponds to a multiple by which the reference amount is multiplied. Note that any number of options may be provided as options for the adjustment amount.

[0034] <Control Unit> The control unit 12 is a controller that controls the washing machine 1. Specifically, the control unit 12 controls the automatic dosing unit 6, the water supply device 10, the drain valve 11, and the operation display unit 14. The control unit 12 includes a general-purpose processor such as a CPU or MPU that executes a program to realize a predetermined function. The control unit 12 calls up and executes a program stored in the storage unit 13 to realize various controls in the washing machine 1. The control unit 12 is not limited to a controller that realizes a predetermined function by cooperation between hardware and software, and may be a hardware circuit designed specifically to realize the predetermined function.

[0035] The control unit 12 sets the settings received by the operation display unit 14 by storing them in the memory unit 13. The control unit 12 changes the display mode of the operation display unit 14 based on the settings stored in the memory unit 13 and the user's operation.

[0036] <Storage section> The storage unit 13 is a recording medium for recording various information and control programs. The storage unit 13 is realized by, for example, a flash memory, a solid state device (SSD), a hard disk, another storage device, or an appropriate combination of these.

[0037] The storage unit 13 stores the received settings of the type of agent and the reference amount of agent. Therefore, the user does not need to input each setting every time an operating course is executed. On the other hand, when each setting is changed, the storage unit 13 stores the changed setting in place of the setting before the change. In other words, the storage unit 13 temporarily stores the setting until it is updated.

[0038] The storage unit 13 stores the received settings for whether or not to automatically supply and the adjustment amount. After the operation course is completed, the control unit 12 may erase the stored settings for whether or not to automatically supply and the adjustment amount. In this case, the user may input the respective settings each time an operation course is executed.

[0039] The memory unit 13 stores, for each operation course, agents belonging to the classification of essential agents and agents belonging to the classification of auxiliary agents. Whether a particular agent is an essential agent or an auxiliary agent varies depending on the operation course. An essential agent in an operation course is an agent used to exert the effect of the operation course. An auxiliary agent in an operation course is an agent used to improve the effect of an essential agent or to supplement an essential agent. An auxiliary agent may exert an effect different from that of an essential agent.

[0040] For example, the memory unit 13 stores detergent and fabric softener as essential agents for the "automatic course" and stores bleach as an auxiliary agent. The memory unit 13 stores detergent and fabric softener as essential agents for the "home cleaning course" and stores bleach as an auxiliary agent. The memory unit 13 stores detergent as essential agents for the "towel only course" and stores fabric softener and bleach as auxiliary agents.

[0041] The auxiliary agent includes an agent such as bleaching agent that may damage laundry or cause abnormal foaming. The auxiliary agent also includes an agent that may have an effect that is not in line with the properties of the clothes that are the target of the operation course or the purpose of the operation course. For example, the auxiliary agent includes an agent such as fabric softener that reduces the absorbency of towels in the "towel only course". Therefore, when the user does not actively want to add the auxiliary agent, it is required to suppress the addition of the auxiliary agent. Therefore, in the first embodiment, the operation display unit 14 displays information regarding the addition of the essential agent and information regarding the addition of the auxiliary agent in a different manner. By such a display, when the agent corresponds to the auxiliary agent, it is possible to switch from a display that prompts the user to add the agent to a display that does not prompt the user to add the agent.

[0042] The memory unit 13 stores, for each operating course, an additive-prohibited agent that is prohibited from being automatically added in the operating course. The additive-prohibited agent is an agent whose automatic addition or non-addition cannot be set to "Yes" in the prohibited operating course. The additive-prohibited agent is an agent that inhibits the effect of the operating course when it is added in the prohibited operating course. The additive-prohibited agent may be an agent that causes solid precipitation or abnormal foaming when mixed with an essential agent of the prohibited operating course. The additive-prohibited agent may be determined based on other agents whose automatic addition or non-addition is set to "Yes". In this case, the memory unit 13 may store a combination of agents whose automatic addition in the same operating course is prohibited.

[0043] The storage unit 13 may be configured to store, for each operation course, an additive-permitted agent that is permitted to be automatically dispensed during the operation course. In this case, agents other than the additive-permitted agents are additive-prohibited agents.

[0044] Next, a more detailed structure of the automatic insertion unit 6 and the manual insertion case 7 will be described. Fig. 2 is a perspective view of the automatic insertion unit 6 and the manual insertion case 7. Fig. 3 is a schematic view of the automatic insertion unit 6 and the manual insertion case 7.

[0045] 2, the automatic dispensing unit 6 has a case 61, tanks 62A to 62C, pump mechanisms 63A to 63C, and a agent discharge flow path 64. The manual dispensing case 7 is housed in the case 61 together with the tanks 62A to 62C, and is disposed in front of the tanks 62A to 62C (the side closer to the front surface of the housing 2 in FIG. 2).

[0046] Case 61 is a container with an open top to accommodate three tanks 62A to 62C and manual throw-in case 7. A back surface 57 of case 61 is connected to agent discharge flow path 64, water supply device 10, and a connection flow path 8 (not shown). Pump mechanisms 63A, 63B, 63C are connected to tanks 62A, 62B, 62C, respectively, via back surface 57. Case 61 has a flow path member 67 along the opening at the top that introduces water supplied from water supply device 10 into manual throw-in case 7.

[0047] As shown in Fig. 3, case 61 has flow paths through which water and agents flow below tanks 62A-62C and manual input case 7. Although one tank 62A and one pump mechanism 63A are shown in Fig. 3, the other tanks 62B-62C and pump mechanisms 63B-63C have the same configuration.

[0048] Returning to Fig. 2, the tanks 62A to 62C are containers for storing the agent, and are housed in the case 61 lined up on the outer side K1 (horizontal direction away from the central axis V0 in Fig. 1). The depths and volumes of the three tanks 62C, 62B, 62A increase in order toward the outer side K1. The tanks 62A to 62C are removable from the case 61 so that the agent can be replenished when the remaining amount becomes low.

[0049] The pump mechanisms 63A, 63B, and 63C are devices that suck out a predetermined amount of agent from the tanks 62A, 62B, and 62C, respectively, and discharge the agent into the agent discharge flow path 64 to supply the agent to the outer tub 3.

[0050] An agent discharge flow path 64 is connected below the pump mechanisms 63A to 63C. The agent discharge flow path 64 is a flow path member whose inlet and outlet are connected to the case 61. The agent discharge flow path 64 returns the water flowing in from the case 61 to the case 61 by merging it with the agent discharged from the pump mechanisms 63A to 63C.

[0051] 3, an outlet 70a is formed at the bottom of the manual input case 7. The agent input into the manual input case 7 immediately passes through the outlet 70a and falls toward the case 61.

[0052] Next, the flow of water and agent in the automatic feeding unit 6 and the manual feeding case 7 will be described.

[0053] First, the supply of water will be described. As shown in Fig. 2, water supplied from the water supply device 10 flows through paths F1 and F2 of the flow path member 67 and flows into the manual insertion case 7. The water that flows into the manual insertion case 7 falls toward the bottom surface of the case 61 through the outlet 70a (Fig. 3).

[0054] 3, the water that has flowed into the case 61 passes below the tanks 62A to 62C along the bottom surface of the case 61 and is then fed into the outer tub 3 via the connecting flow path 8 (FIG. 1). Some of the water that has flowed into the case 61 flows from the case 61 into the agent discharge flow path 64, flows through the agent discharge flow path 64, and then flows back into the case 61, before being fed into the outer tub 3 via the connecting flow path 8.

[0055] Next, the flow of the agent will be described. In the case of automatic dispensing, the agent is sucked laterally from the tank 62A by the pump mechanism 63A and discharged downward toward the agent discharge flow path 64. In the agent discharge flow path 64, the agent merges with the water that has flowed into the agent discharge flow path 64 from the case 61. The agent flows through the agent discharge flow path 64 together with the water, and flows into the case 61. The agent is then supplied to the outer tub 3 together with the water via the connection flow path 8. That is, the agent is supplied to the outer tub 3 by the flow of water that occurs when water is supplied.

[0056] In the case of manual addition, the agent flows into the case 61 together with water and is supplied to the outer tank 3.

[0057] Next, the screens displayed by the operation display unit 14 will be described in more detail.

[0058] Before an operating course is executed, the operation display unit 14 displays a setting screen D1 for displaying to the user the type of agent contained in the tanks 62A to 62C and whether or not automatic injection is enabled. Figures 4A to 4E are schematic diagrams of the operation display unit 14 displaying the setting screen D1. In Figures 4A to 4E, hatching of different patterns illustrates different colors.

[0059] As shown in Figures 4A to 4E, the setting screen D1 has a setting display 16 that displays settings for the type of agent in the tanks 62A to 62C and whether or not automatic dispensing is enabled. The setting display 16 has icons 16A to 16C and labels 18A to 18C that correspond to the tanks 62A to 62C, respectively. The icons 16A to 16C are made up of a combination of figures and numbers, and the labels 18A to 18C are made up of letters.

[0060] The icons 16A to 16C display identification information of the tanks. Specifically, the icons 16A to 16C display numbers for identifying the tanks 62A to 62C. In the first embodiment, the tank 62A is identified by "1", the tank 62B by "2", and the tank 62C by "3". The labels 18A to 18C display in text the type of agent contained in the corresponding tank.

[0061] The control unit 12 changes the color of the icons 16A to 16C depending on the type of agent contained in the corresponding tank. Comparing Figures 4A and 4B, the color of the icon 16C differs depending on whether the agent contained in the tank 62C is a bleach agent or a delicates detergent.

[0062] The control unit 12 changes the display form of the icons 16A to 16C depending on the setting of whether or not the agent is automatically dispensed into the tanks 62A to 62C. As shown in Figs. 4A and 4B, when the setting of whether or not the agent is automatically dispensed into the tank 62C is set to "Yes", the control unit 12 causes the operation display unit 14 to display the icons 16A to 16C in color. On the other hand, as shown in Fig. 4C, when the setting of whether or not the agent is automatically dispensed into the tank 62C is set to "No", the control unit 12 causes the operation display unit 14 to display the icon 16C in a grayed-out state. The control unit 12 may also cause the operation display unit 14 to display the label 18C in a grayed-out state.

[0063] This display mode allows the user to recognize that the automatic insertion setting is set to "off." Also, compared to when icon 16C and label 18C are not displayed, it is easier for the user to recognize that the automatic insertion setting can be changed to "on."

[0064] Furthermore, the control unit 12 changes the display form of the icons 16A to 16C depending on the set operating course and the setting of the type of agent in the tanks 62A to 62C. Specifically, the control unit 12 refers to the memory unit 13 and determines whether or not the agent corresponds to an agent whose addition is prohibited in the set operating course. As shown in FIG. 4D, when the agent in the tank 62C corresponds to an agent whose addition is prohibited, the control unit 12 causes the label 18C to display that the addition of the agent is prohibited. Specifically, the control unit 12 changes the text on the label 18C from the type of agent to "Addition not permitted". The control unit 12 may also change the color of the label 18C.

[0065] With this display format, the operation display unit 14 can display that the automatic feeding of the feeding-prohibited agent cannot be set to "yes" in the set operating course.

[0066] As a modification of the display mode shown in FIG. 4D, when the agent in tank 62C corresponds to an agent that is prohibited from being added, control unit 12 may cause operation display unit 14 to display a cross mark on icon 16C, as shown in FIG. 4E.

[0067] Although an example in which the display form of the icon 16C and the label 18C are changed has been described above, the control unit 12 similarly changes the display form of the icons 16A, 16B and the labels 18A, 18B according to settings related to the agents in the tanks 62A, 62B.

[0068] In the setting screen D1, the setting display 16 can be pressed. When the user presses the setting display 16, the control unit 12 causes the operation display unit 14 to display the input setting change screen D2. The input setting change screen D2 is a screen that can accept changes to the setting of whether or not to automatically input and the setting of the adjustment amount according to the user's operation.

[0069] 5A and 5B are schematic diagrams of the operation display unit 14 displaying the input setting change screen D2. In Fig. 5A and Fig. 5B, hatching of different patterns illustrates different colors.

[0070] 5A, the supply setting change screen D2 has detailed setting displays 71A-71C corresponding to the tanks 62A-62C, respectively, and a decision button 72. The detailed setting displays 71A-71C display the tank identification information, the type of agent, the reference amount, whether or not automatic supply is enabled, and the adjustment amount.

[0071] In the first embodiment, the detailed setting displays 71A to 71C include icons similar to the icons 16A to 16C, and indicate the types of agents in the tanks 62A to 62C through the colors of the icons.

[0072] In the supply setting change screen D2, the detailed setting displays 71A to 71C can be pressed. When the user presses the detailed setting displays 71A to 71C, the setting of whether or not to automatically supply water to the tanks 62A to 62C and the adjustment amount can be changed.

[0073] Specifically, as shown in FIG. 5B, when the user presses the detailed setting display 71A, the control unit 12 displays input setting options 73 on the operation display unit 14. When the user presses "None" in the option 73, the operation display unit 14 accepts the "None" setting as the presence or absence of automatic input. On the other hand, when the user presses any of "Less," "Standard," and "More" in the option 73, the operation display unit 14 accepts the setting of the adjustment amount and accepts the "Yes" setting as the presence or absence of automatic input. Also, when the user presses an adjustment amount ("Less," "More") different from the set adjustment amount ("Standard" in FIG. 5B), the operation display unit 14 accepts the change of the adjustment amount. The operation display unit 14 displays the changed setting.

[0074] In response to pressing of the decision button 72, the control unit 12 may store the accepted information on whether or not to perform automatic input and the amount of adjustment in the storage unit 13.

[0075] During execution of an operating course, the operation display unit 14 displays an agent input screen D3 showing information related to the input of an agent in the operating course. Figures 6A to 6C are schematic diagrams of the operation display unit 14 displaying the agent input screen D3. In Figures 6A to 6C, hatching of different patterns illustrates different colors.

[0076] 6A to 6C, the agent input screen D3 has agent indicators 27 to 29 that can display the agents that can be input during the operation course. The control unit 12 changes the display of the agent indicators 27 to 29 depending on whether the corresponding agent is automatically input and the classification (essential agent or supplementary agent).

[0077] In the following description, an example will be described in which the washing machine 1 is executing the "automatic course." In the "automatic course," detergent and fabric softener are essential agents, and bleach is an auxiliary agent. Thus, agent display 27 corresponds to detergent, agent display 28 corresponds to fabric softener, and agent display 29 corresponds to bleach. The detergent is stored in tank 62A, the fabric softener in tank 62B, and the bleach in tank 62C.

[0078] 6A shows the agent supply screen D3 when the automatic supply status is set to "Yes" for all of the agents in the tanks 62A to 62C. In this case, the agent displays 27 to 29 are displayed in the automatic supply mode (third display mode).

[0079] As shown in Fig. 6A, agent displays 27-29 in the automatic dispensing mode display the type of agent, identification information of the tank in which the agent is stored, and the dispensing method (automatic dispensing). Agent displays 27-28 for essential agents in the automatic dispensing mode further display information regarding the amount to be dispensed. Agent display 29 for auxiliary agents in the automatic dispensing mode does not display information regarding the amount to be dispensed. By limiting the display of information regarding the amount of auxiliary agent to be dispensed, it is possible to prevent the user from manually dispensing more agent than the displayed amount to be dispensed, thereby preventing over-dosing.

[0080] In the first embodiment, the operation display unit 14 displays the input amount in the unit of "cups" as information on the input amount, but is not limited to this. For example, the input amount may be displayed in the unit of "mL."

[0081] In the automatic drug supply mode, the drug displays 27-29 are displayed in order from the top. The drug displays 27-28 of the essential drugs are displayed at the top of the drug supply screen D3, and the drug display 29 of the supplementary drug is displayed at the bottom of the drug supply screen D3.

[0082] The agent displays 27-29 in the automatic dispensing mode include an icon that displays identification information of the tank. In the automatic dispensing mode, the icon indicates the identification number of the tank in which the agent is stored. The icon has a color corresponding to the type of agent. Although not shown for convenience, other displays of the agent displays 27-29 may also have a color corresponding to the type of agent.

[0083] 6B shows the agent supply screen D3 when the automatic supply setting is set to "No" for all of the agents in the tanks 62A to 62C. In this case, the agent displays 27 to 29 are displayed in the first display mode or the second display mode.

[0084] The control unit 12 determines whether to apply the first display mode or the second display mode to the agent displays 27-29 depending on the classification (essential agent or supplementary agent) of the agent to which the agent displays 27-29 correspond (i.e., the agent in the tank 62A-62C). In the case of an essential agent, the control unit 12 applies the first display mode. In the case of a supplementary agent, the control unit 12 applies the second display mode.

[0085] In FIG. 6B, essential agent indications 27-28 are displayed in a first display manner, and auxiliary agent indication 29 is displayed in a second display manner.

[0086] As shown in FIG. 6B, the agent displays 27-28 in the first display mode maintain an area for displaying information related to the supply, in contrast to the automatic supply mode. The agent displays 27-28 in the first display mode display information related to manual supply. Specifically, the agent displays 27-28 in the first display mode display information related to the manual supply, such as the type of agent, the supply method (manual supply), and the supply amount. In the first display mode, the icons of the agent displays 27-28 do not display tank identification information and are displayed grayed out. Other displays of the agent displays 27-28 may maintain a color according to the type of agent.

[0087] The second display mode is a display mode in which information regarding manual drug input is reduced or the displayed information is made more difficult to recognize than in the first display mode. In the first embodiment, in the second display mode, the drug display 29 is not displayed on the drug input screen D3. In other words, the display of the drug display 29 is restricted on the drug input screen D3.

[0088] Since the drug display 29 is not displayed, the information regarding manual input and the input amount of the auxiliary drug are not displayed. Specifically, the drug display 29 in the second display mode does not display, as information regarding manual input, a message suggesting that manual input is possible or a message encouraging manual input.

[0089] In the first display mode, the agent displays 27-28 are displayed in the upper part of the agent input screen D3. In the lower part of the agent input screen D3, a blank space in which the display of information regarding the manual input of auxiliary agents is restricted is displayed instead of the agent display 29. The blank space corresponds to the area of ​​the agent display 29 in the automatic input mode.

[0090] FIG. 6C shows a modified example of the agent supply screen D3 when the automatic supply status is set to "no" for all of the agents in the tanks 62A to 62C.

[0091] The drug displays 27-28 in the first display mode shown in Fig. 6C display other information related to the manual input of the essential drug in addition to the input method and input amount. In the first embodiment, the drug displays 27-28 display a message directly urging the user to input the essential drug manually, such as "Please input manually."

[0092] The drug display 29 in the second display mode shown in Fig. 6C displays the type of drug and the injection method (manual injection). The drug display 29 in the second display mode displays a message encouraging manual injection in a more passive manner than the drug displays 27-28 in the first display mode, such as "Inject an appropriate amount as needed." In the second display mode, the icon of the drug display 29 is displayed grayed out. The icon of the drug display 29 may be displayed lighter than the icons of the drug displays 27-28 for essential drugs.

[0093] The agent display 29 in the second display mode does not display the amount of the agent inserted. On the other hand, the agent display 29 in the second display mode may display the amount of the agent inserted.

[0094] The control unit 12 may determine whether to apply the display mode of FIG. 6B or the display mode of FIG. 6C on the agent dispensing screen D3 based on the set operating course.

[0095] The agent displays 27 to 29 may further display other information. For example, the agent displays 27 to 29 may further display the setting of the adjustment amount of the agent. When the operation display unit 14 receives the setting of the brand in response to the user's operation, the agent displays 27 to 29 may further display the set brand.

[0096] [Operation] Next, a description will be given of the operation of the washing machine 1. Fig. 7 is a flow chart showing the operation of the washing machine 1.

[0097] As shown in FIG. 7, first, the operation display unit 14 accepts a setting of the type of agent and a setting of the reference amount of the agent in response to a user's operation (S1). Specifically, the operation display unit 14 displays "bleach" and "delicate detergent" as options for the type of agent in the tank 62C. The operation display unit 14 accepts the option pressed by the user. Furthermore, the operation display unit 14 accepts a setting of the reference amount of the agent in the tanks 62A to 62C. The control unit 12 stores the settings accepted by the operation display unit 14 in the memory unit 13 in response to a predetermined operation by the user (for example, pressing the "OK" button).

[0098] Next, the operation display unit 14 accepts the setting of the operation course in response to the user's operation (S2). Specifically, the operation display unit 14 displays options for the operation course and accepts the option pressed by the user. The control unit 12 stores the setting accepted by the operation display unit 14 in the storage unit 13 in response to a predetermined operation by the user (e.g., pressing the "OK" button).

[0099] Next, the operation display unit 14 accepts a setting for whether or not to automatically add the agent to the tanks 62A-62C and a setting for the adjustment amount in response to a user operation (S3). The control unit 12 stores the settings accepted by the operation display unit 14 in the memory unit 13 in response to a predetermined operation by the user (for example, pressing the decision button 72).

[0100] Next, the control unit 12 determines whether the automatic supply of agent to the tank 62A is set to "No" (S4). Specifically, the control unit 12 refers to the memory unit 13 and determines whether the automatic supply is set to "No".

[0101] When the automatic supply is set to "No" (Yes in S4), the control unit 12 determines whether the agent in the tank 62A is an essential agent (S5). Specifically, the control unit 12 refers to the memory unit 13 and determines the classification of the agent (whether it is an essential agent or a supplementary agent) based on the setting of the operation course and the setting of the type of agent.

[0102] When the automatic supply is set to "Yes" (No in S4), the control unit 12 determines to display the agent display 27 in the automatic supply mode (third display mode) on the agent supply screen D3 (S6).

[0103] If the agent in the tank 62A is an essential agent (Yes in S5), the control unit 12 determines to display the agent display 27 in the first display mode (S7).

[0104] If the agent in the tank 62A is a supplementary agent (No in S5), the control unit 12 determines to display the agent display 27 in the second display mode (S8).

[0105] The control unit 12 repeats steps S4 to S8 for the agent in the tank 62B and the agent in the tank 62C.

[0106] Next, the control unit 12 executes the operation course accepted in step S2 (S10). The control unit 12 causes the operation display unit 14 to display the agent insertion screen D3 based on the display mode determined in steps S4 to S8.

[0107] Next, an example in which the washing machine 1 executes an operation program different from the above-mentioned "automatic program" will be described. The following mainly describes the differences in the display on the operation display unit 14 from the "automatic program".

[0108] 8A and 8B show the agent dispensing screen D3 in the "delicate course" executed to wash delicate clothes. In the "delicate course", detergent and fabric softener are essential agents. Detergents include normal detergent and detergent for delicate clothes. Furthermore, if automatic dispensing of detergent for delicate clothes is set to "yes", normal detergent is prohibited from being dispensed. If it is prohibited from being dispensed, automatic dispensing of normal detergent cannot be set to "yes". Thus, agent display 37 corresponds to normal detergent, agent display 38 to fabric softener, and agent display 39 to detergent for delicate clothes. Furthermore, it is assumed that normal detergent is stored in tank 62A, fabric softener in tank 62B, and detergent for delicate clothes in tank 62C.

[0109] 8A shows an agent supply screen D3 when the automatic supply status for agents in the tanks 62B to 62C is set to "Yes." In this case, the agent displays 38 to 39 are displayed in the automatic supply mode (third display mode).

[0110] When the automatic dispensing of delicate detergent in tank 62C is set to "Yes", the regular detergent in tank 62A corresponds to a prohibited agent. Therefore, the agent display 37 corresponding to the regular detergent is not displayed on the agent dispensing screen D3. Note that the agent display corresponding to the prohibited agent may be displayed on the agent dispensing screen D3. In this case, the agent display 37 may be displayed in a display mode different from the automatic dispensing mode, such as "Do not dispense", to indicate that the automatic dispensing of the agent cannot be set to "Yes".

[0111] 8B shows the agent supply screen D3 when the automatic supply of agents in the tanks 62A to 62C is set to "no." In this case, the agent displays 37 to 39 are displayed in the first display mode.

[0112] When the automatic dispense setting for both tanks 62A and 62C is set to "no," the user is required to manually dispense a normal detergent or a delicate detergent as a required agent. Therefore, as shown in FIG. 8B, the agent displays 37 and 39 in the first display mode are displayed together. By displaying them together, it is easy for the user to recognize that it is necessary to dispense either one of them.

[0113] Next, an example in which the washing machine 1 executes an operation program different from the above-mentioned "automatic program" and "delicate program" will be further described. The following mainly describes the display on the operation display unit 14 that is different from the "automatic program".

[0114] 9A to 9B show the detergent dispense screen D3 in the "detergent course" which is executed to break down dirt attached to clothes before washing with a dedicated detergent and make it easier to remove in the washing process. The dedicated detergent may be called a pre-treatment agent. In the "detergent course", the first detergent and fabric softener are essential agents, and the bleach and second detergent are auxiliary agents. Thus, the detergent display 47 corresponds to the first detergent, the detergent display 48 corresponds to the fabric softener, the detergent display 49 corresponds to the bleach, and the detergent display 50 corresponds to the second detergent. In addition, the first detergent is stored in tank 62A, the bleach in tank 62B, and the second detergent in tank 62C. Since the fabric softener is not stored in any tank, the automatic softener dispense setting cannot be set to "Yes".

[0115] 9A shows an agent supply screen D3 when the automatic supply of agents in the tanks 62A to 62C is set to "Yes." In this case, the agent displays 47, 49 to 50 are displayed in the automatic supply mode (third display mode).

[0116] In addition, since fabric softener is an essential agent, the agent display 48 corresponding to the fabric softener displays information regarding the type of agent, the method of adding (manual addition), and the amount added. The icon of the agent display 48 does not display the tank identification information, and is displayed grayed out.

[0117] The drug displays 47-50 are displayed in order from top to bottom. The drug displays 47-48 of essential drugs are displayed at the top of the drug input screen D3, and the drug displays 49-50 of supplementary drugs are displayed at the bottom of the drug input screen D3. The drug displays 47-48 of essential drugs have a larger area than the drug displays 49-50 of supplementary drugs. The drug displays 47-48 may have an area twice or more larger than that of the drug displays 49-50. Therefore, the drug displays 47-48 of essential drugs are easier for the user to recognize than the drug displays 49-50 of supplementary drugs.

[0118] 9B shows the agent input screen D3 when the automatic input status is set to "No" for all of the agents in the tanks 62A-62C. In this case, the agent displays 47-48 of the essential agents are displayed in the first display mode, and the agent displays 49-50 of the auxiliary agents are displayed in the second display mode. That is, the agent displays 49-50 are not displayed on the agent input screen D3.

[0119] The agent displays 49-50 in the second display mode may be displayed on the agent input screen D3. In this case, the agent displays 47-48 in the first display mode have a larger area than the agent displays 49-50 in the second display mode.

[0120] The above description is summarized to describe the features of the present disclosure.

[0121] The auxiliary agent may damage laundry or cause abnormal foaming, so there is a need to suppress the addition of the auxiliary agent when the user does not actively want to add the auxiliary agent.

[0122] Even when the auxiliary agent is not automatically dispensed, the user can manually dispense the auxiliary agent. If the agent dispense screen D3 displays that the auxiliary agent can be manually dispensed and the amount to be dispensed, the user may easily dispense the auxiliary agent manually. Therefore, in the first embodiment, when the automatic dispense of the agent is not executed, the control unit 12 changes the display mode of the agent displays 27 to 29 corresponding to the agent depending on whether the agent is an essential agent or an auxiliary agent.

[0123] Specifically, when the agent that is not automatically dispensed is an auxiliary agent, the control unit 12 hides the agent displays 27-29 corresponding to the auxiliary agent. That is, the control unit 12 hides the method of dispensing the auxiliary agent and the amount to be dispensed. Such a display can prevent the user from manually dispensing the auxiliary agent carelessly. By making the user take the trouble of referring to the instruction manual to check the amount to be dispensed, the user will manually dispense the auxiliary agent only when the dosage of the auxiliary agent is appropriate. It is possible to prevent unnecessary dispensing of the auxiliary agent. Therefore, the convenience of the washing machine 1 is improved.

[0124] On the other hand, when an agent that is not automatically dispensed corresponds to a required agent, the control unit 12 prompts the user to manually dispense the agent on the agent display 27 to 29 corresponding to the required agent. By such a display, the effect of the operating course is more reliably achieved.

[0125] Furthermore, even when automatic supplementary agent is dispensed, the control unit 12 hides the dispensed amount in the agent displays 27 to 29 corresponding to the supplementary agent. By displaying in this manner, even when automatic supplementary agent is dispensed, the user is prevented from manually dispensing the supplementary agent, and double or excessive supplementation of the supplementary agent can be prevented.

[0126] [effect] The washing machine 1 according to the first embodiment can provide the following effects.

[0127] The washing machine 1 of the first embodiment includes a washing tub 4, a tank 62C (first tank) capable of storing a first agent, a pump mechanism 63C (first automatic dispenser) that dispenses the first agent into the washing tub 4, an operation display unit 14 (operation unit and display unit), and a control unit 12. The operation display unit 14 is capable of displaying an agent display 29 (first agent dispense display) showing information regarding the dispense of the first agent. The operation display unit 14 is capable of receiving a setting of an operation course, a setting of the type of the first agent, and a setting of whether or not the first agent is to be automatically dispensed by the pump mechanism 63C in the operation course (with or without dispense). When the automatic dispense of the first agent is set to no, the control unit 12 determines the classification of the first agent based on the setting of the operation course and the setting of the type of the first agent. When the classification of the first agent is the first classification, the control unit 12 causes the operation display unit 14 to display the agent display 29 in a first display mode. When the classification of the first agent is the second classification, the control unit 12 causes the operation display unit 14 to display the agent display 29 in the second display mode.

[0128] With this configuration, when the automatic dispense setting is set to "no," the display mode of the agent dispense screen can be switched between, for example, a mode that prompts manual dispense of the agent and a mode that does not prompt, by changing the display mode according to the type of agent. This improves the usability of the washing machine 1.

[0129] In addition, in the washing machine 1 of the first embodiment, the first category is a category of essential agents in the operation course, and the second category is a category of auxiliary agents in the operation course.

[0130] With this configuration, the operation display unit 14 can apply a display mode that suppresses manual input of auxiliary agents, and a display mode that prompts manual input of essential agents.

[0131] In addition, in the washing machine 1 of the first embodiment, the operation display unit 14 does not display information related to the manual addition of the first agent in the second display mode.

[0132] This configuration can reduce the need to manually dispense the auxiliary agent, thereby reducing damage to clothes caused by unnecessary dispense of the auxiliary agent.

[0133] In addition, in the washing machine 1 of the first embodiment, the operation display unit 14 does not display the amount of the first agent dispensed in the second display mode.

[0134] With this configuration, the amount of supplementary agent added is not notified to the user, which further reduces the need to manually add supplementary agent.

[0135] In addition, in the washing machine 1 of the first embodiment, in the second display mode, the operation display unit 14 displays a blank space that restricts information regarding the manual addition of the first agent.

[0136] With this configuration, manual injection of auxiliary agents can be further suppressed by not displaying the agent display 29.

[0137] In the washing machine 1 of the first embodiment, the operation display unit 14 displays information regarding the manual addition of the first agent in the first display mode.

[0138] With this configuration, the user can be prompted to manually input the charge, and the effect of the operating course can be more reliably achieved.

[0139] In the washing machine 1 of the first embodiment, the operation display unit 14 displays the amount of the first agent dispensed in the first display mode.

[0140] With this configuration, the user can be informed of the amount to be added, which can further encourage the user to manually add the essential agent.

[0141] In addition, in the washing machine 1 of the first embodiment, the operation display unit 14 is configured so that the display unit and the operation unit are integrated together.

[0142] With this configuration, the space required for the operation and display unit 14 can be reduced.

[0143] Furthermore, in the washing machine 1 of the first embodiment, the operation display unit 14 displays the agent display 29 in different colors depending on the type of the first agent.

[0144] This configuration makes it easier to identify the type of agent.

[0145] In addition, in the washing machine 1 of the first embodiment, the operation display unit 14 displays, in the agent display 29, identification information related to the tank 62C.

[0146] This configuration makes it easier to recognize which tank contains which agent.

[0147] The display method of the first embodiment includes receiving a setting of an operation course, a setting of the type of the first agent contained in tank 62C, and a setting of whether or not the first agent is to be automatically dispensed by pump mechanism 63C that dispenses the first agent into washing tub 4 in the operation course (S1 to S3). The display method includes determining the classification of the first agent based on the setting of the operation course and the setting of the type of the first agent when the automatic dispense of the first agent is set to no (Yes in S4) (S5). The display method includes displaying agent display 29 showing information regarding the dispense of the first agent in a first display mode when the classification of the first agent is the first classification (S7). The display method includes displaying agent display 29 in a second display mode different from the first display mode when the classification of the first agent is the second classification (S8).

[0148] The present disclosure is not limited to the embodiments, and can be embodied in various other forms.

[0149] In the first embodiment, the washing machine 1 has three tanks 62A to 62C, but the present invention is not limited to this. The washing machine 1 may have any number of tanks. In this case, the washing machine 1 has the same number of pump mechanisms as the tanks.

[0150] In the first embodiment, the type of agent contained in the tanks 62A and 62B is fixed, but the present invention is not limited to this. The tanks 62A and 62B may contain agents of a type arbitrarily selected by the user.

For example, the operation unit 14A may be composed of a plurality of physical buttons, and the display unit 14B may be composed of an LCD display.

[0152] In the first embodiment, an example in which the user inputs information regarding the automatic administration of the agent through the operation and display unit 14 has been described, but the present invention is not limited to this. For example, the user may input information regarding the automatic administration of the agent through an application stored in an external terminal such as the user's smartphone instead of or in addition to the operation and display unit 14. In this case, the control unit 12 further includes a communication unit for directly communicating with the external terminal or for communicating with the external terminal via a server.

[0153] In the first embodiment, the control unit 12 displays the agent input screen D3 on the operation display unit 14 and changes the display mode of the agent displays 27 to 29. However, the present invention is not limited to this. For example, the control unit 12 may communicate with an external terminal such as a user's smartphone via a server, display the agent input screen D3 on an application stored in the external terminal, and change the display mode of the agent displays 27 to 29. The control unit 12 may also display other information related to the operation status of the washing machine on the application stored in the external terminal via the server. In this case, the control unit 12 further has a communication unit for communicating with the external terminal via the server.

The agent display 29 in the second display mode may be displayed on the agent input screen D3. In this case, the agent display 29 in the second display mode may be referred to as a no-automatic-input display. For example, the agent display of the auxiliary agent in the second display mode may be displayed grayed out. In this case, the agent display of the auxiliary agent in the second display mode may be lighter than the agent display of the essential agent in the first display mode.

[0156] In the first embodiment, the control unit 12 identifies the tanks 62A to 62C by numbers, but this is not limiting. For example, the control unit 12 may identify the tanks 62A to 62C by the relative positions of the tanks 62A to 62C in the housing 2.
