Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional washing machine, there is a possibility of incorrect use of the treatment agent due to the complexity of the settings. When an incorrect use occurs, since the control unit internally controls the introduction unit, it is difficult for the user to immediately notice the mistake.

[0005] An object of the present invention is to provide a washing machine with improved visibility regarding the setting of the liquid agent to be introduced when a configuration capable of using multiple liquid agents is adopted. [Means for solving the problem]

[0006] [1] A washing machine according to one aspect of the present disclosure includes a dispensing device having a plurality of storage sections for storing a plurality of liquids, a setting display section for displaying at least one liquid to be dispensed from among the plurality of liquids, and a control unit for controlling the setting display section and controlling the dispensing device so that the liquid to be dispensed is dispensed at a predetermined timing, wherein the dispensing device has light-emitting sections provided in each of the plurality of storage sections, and the control unit displays in the setting display section that a liquid to be dispensed is to be dispensed, and in conjunction with the display, causes the light-emitting sections provided in the storage sections for storing the liquid to be dispensed to emit light.

[0007] According to the washing machine in [1], each of the multiple storage compartments is equipped with a light-emitting unit. When the setting display unit indicates that a liquid to be used is to be added, the control unit causes the light-emitting unit of the storage compartment corresponding to the liquid to be used to illuminate in conjunction with the display. Therefore, the user can see (confirm) the display on the setting display unit and the illumination of the storage compartment corresponding to the liquid to be used together or in succession. Normally, a specific type of liquid is poured into the storage compartment by the user. The user can easily see the storage compartment containing the liquid to be used (i.e., the liquid to be added in the current cycle). This washing machine is equipped with a dispensing device that allows the use of multiple liquids, but the visibility of the liquid setting can be improved. For example, even if a mistake in use occurs due to some factor, the user can immediately notice the mistake.

[0008] [2] In the washing machine described in [1] above, the plurality of storage units include at least one custom agent storage unit for storing custom agents, and the setting display unit has a custom agent setting unit for setting custom agents, and the custom agent setting unit may include at least one of a first selection unit for selecting the type of custom agent and a second selection unit for selecting the amount of custom agent to be added. With this configuration, the user can perform laundry according to their preferences and purposes (for example, a washing course using a predetermined liquid agent) by selecting the type of custom agent in the first selection unit. Alternatively, the user can perform laundry according to their preferences and purposes (for example, laundry with a predetermined concentration of custom agent) by selecting the amount of custom agent to be added in the second selection unit. The operation of each selection operation is excellent.

[0009] [3] In the washing machine described in [2] above, the custom agent setting unit includes both a first selection unit and a second selection unit, and the control unit may display on the setting display unit that the custom agent will be added as a liquid agent, provided that both the selection of the type of custom agent in the first selection unit and the selection of the amount of custom agent to be added in the second selection unit have been made. With this configuration, the setting display unit will only display that the custom agent will be added after the type of custom agent has been appropriately set and the amount of that custom agent to be added has been appropriately set. In other words, the custom agent will not actually be added unless both settings have been made. This prevents errors in setting the custom agent. The user can intuitively complete the setting of the custom agent by performing sequential operations (button operation, etc.).

[0010] [4] In the washing machine described in [3] above, the setting display unit is capable of displaying the type of custom agent selected in the custom agent setting unit and the amount of custom agent to be added. When the type of custom agent is changed in the first selection unit, the control unit may turn off the display of the amount to be added and the display indicating that the custom agent will be added as a liquid agent to be used in the setting display unit. With this configuration, when the type of custom agent is changed, the control unit cancels the setting of the amount to be added and the setting for adding that custom agent. This allows the user to be prompted to set the amount to be added and prevents the changed custom agent from being added in the amount based on the previous setting (incorrect amount).

[0011] [5] In any one of the washing machines described in [2] to [4] above, the multiple storage units further include detergent storage units for storing detergent, the setting display unit further includes a detergent setting unit for setting the detergent, the types of custom agents that can be selected in the custom agent setting unit include detergent, and the detergent setting may be made based on the setting operation made later in the detergent setting unit and the custom agent setting unit. For example, a first type of detergent is poured into the detergent storage unit and a second type of detergent is poured into the custom agent storage unit. At this time, the detergent to be added (the detergent to be used) is set based on the setting operation made later in the detergent setting unit and the custom agent setting unit. Thus, duplicate detergent addition is avoided. Illumination of any of the storage units can prevent the use of the wrong detergent (for example, adding a type of detergent different from the user's intention).

[0012] [6] In any one of the washing machines described in [2] to [5] above, the multiple storage units further include a fabric softener storage unit for storing fabric softener, the setting display unit further includes a fabric softener setting unit for setting the fabric softener, the types of custom agents that can be selected in the custom agent setting unit include fabric softener, and the setting of the fabric softener may be made based on the setting operation made later in the fabric softener setting unit and the custom agent setting unit. For example, a first type of fabric softener is poured into the fabric softener storage unit, and a second type of fabric softener is poured into the custom agent storage unit. At this time, the fabric softener to be added (the fabric softener to be used) is set based on the setting operation made later in the fabric softener setting unit and the custom agent setting unit. Thus, duplicate dispensing of fabric softener can be avoided. Illumination of any of the storage units can prevent the use of fabric softener incorrectly (for example, dispensing a type of fabric softener different from the user's intention).

[0013] [7] In any one of the washing machines described in [1] to [6] above, the control unit may store the settings for the liquid to be used even after the washing machine is turned off, and when the washing machine is turned on, it may display on the setting display unit that the liquid to be used will be added based on the stored settings for the liquid to be used, and in conjunction with this display, it may also illuminate the light-emitting unit provided in the storage unit that stores the liquid to be used. With this configuration, the liquid usage conditions from the previous operation are stored, and there is no need to set the same liquid usage conditions again. Therefore, convenience for the next use is improved.

[0014] [8] In any one of the washing machines described in [1] to [7] above, the control unit may display on the setting display unit that the liquid to be used is being added, and simultaneously with this display, the light-emitting unit provided in the storage unit for storing the liquid to be used may be illuminated. With this configuration, the user can visually confirm (confirm) both the display on the setting display unit and the illumination of the storage unit corresponding to the liquid to be used, thereby further improving the visibility described above. [Effects of the Invention]

[0015] According to the present invention, in a washing machine provided with a dosing device capable of using a plurality of liquid agents, the visibility regarding the setting of the liquid agent to be used can be improved.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted. The dimensional ratios in the drawings do not necessarily match those in the description.

[0018] Referring to FIGS. 1 and 2, the basic configuration of the washing machine 1 according to an embodiment will be described. In the following description, the X direction, Y direction, and Z direction orthogonal to each other shown in FIGS. 1 and 2 may be used to describe the washing machine 1. The X direction, Y direction, and Z direction correspond to the front-rear direction, left-right direction, and height direction (or up-down direction or vertical direction) in the installation state of the washing machine 1 shown in FIGS. 1 and 2. Terms indicating directions such as “front”, “rear”, “up”, “down”, “left”, and “right” are terms based on the installation state of the washing machine 1 shown in FIG. 1.

[0019] As shown in FIGS. 1 and 2, the washing machine 1 is, for example, a vertical washing machine. The washing machine 1 includes a housing 2. The housing 2 constitutes the outer shell of the washing machine 1. The housing 2 has a hollow body portion 2a with an open upper surface and a lower surface. An outer tub 5a and an inner tub (or washing tub) 5b are arranged inside the body portion 2a. The upper surface of the body portion 2a is covered with an upper panel portion 2b, and a pedestal 2c is attached to the lower surface of the body portion 2a. When viewed from the Z direction, the shape of the body portion 2a is square (rectangular or square).

[0020] A laundry loading opening 2e is formed in the top panel 2b. The loading opening 2e is located above the inner tub 5b housed in the casing 2 and is covered by the top lid 3. The top lid 3 is attached to the top panel 2b so as to be able to be opened and closed. The top lid 3 rotates around a pivot axis L1 that extends in the left-right direction at the rear end of the top panel 2b. As shown in Figure 1, the top lid 3 has a rectangular plate-shaped rear lid 3a that is rotatably attached to the rear end of the top panel 2b, and a rectangular plate-shaped front lid 3b that is foldably connected to the front end of the rear lid 3a. The rear lid 3a is connected to the top panel 2b via a rotation axis mechanism including a damper and is rotatable relative to the top panel 2b around the pivot axis L1. The front lid 3b is connected to the rear lid 3a via a hinge structure and is foldable relative to the rear lid 3a around a folding axis L2. The folding axis L2 is parallel to the rotation axis L1 and moves above the input opening 2e in accordance with the rotation of the rear cover 3a. In the direction of the folding axis L2, the length (width) of the front cover 3b is equal to the length (width) of the rear cover 3a. In the extending direction of each plate-like member perpendicular to the folding axis L2, the length of the front cover 3b is shorter than the length of the rear cover 3a (see Figure 2).

[0021] When the top lid 3 is closed (see Figure 1), the rear lid 3a and the front lid 3b are aligned front to back at the same inclination, forming a single flat top lid 3 that covers the input opening 2e. The top lid 3 is inclined, for example, to become lower towards the front. The rear lid 3a is provided with a transparent section 3c, allowing visibility of the interior even when the top lid 3 is closed. The front lid 3b has a handle section 3d for opening and closing the top lid 3. When the front lid 3b is lifted by the user, the rear lid 3a rotates around the pivot axis L1 and the front lid 3b folds around the folding axis L2 simultaneously, opening the top lid 3. As shown in Figure 2, the top lid 3 maintains its fully open position when the rear lid 3a is stopped by a stopper mechanism at a predetermined rotational position (a slightly rearward-tilted position). In this position, the front cover 3b hangs down so as to overlap the rear cover 3a. The closing operation of the top cover 3 is performed in the reverse order of the opening operation described above, by the user pulling the front cover 3b forward.

[0022] A panel-shaped control unit 4, elongated in the left-right direction (Y direction), is provided at the rear end of the top panel 2b. The control unit 4 has an inclined surface equal to that of the closed top lid 3 (see Figure 1) and is positioned within a range where the user can operate it by hand while visually observing it. The control unit 4 is equipped with several buttons for operating the washing machine 1. The control unit 4 can fit into the opening 3e (see Figure 2) between a pair of arm sections 3f located at the left and right rear of the rear lid 3a, and does not interfere with the opening and closing operation of the top lid 3. Even when the top lid 3 is fully open, the control unit 4 is exposed between the hanging front lid 3b and the loading opening 2e and can be operated by the user. In other words, the control unit 4 can be operated whether the top lid 3 is closed or open.

[0023] A control unit 30 (see Figure 4) that controls the operation of each part of the washing machine 1 is installed at an appropriate location in the upper part of the housing 2. The operation unit 4 is electrically connected to the control unit 30. As shown in Figure 4, the control unit 30 is, for example, a microcomputer and has a CPU 31, memory 32, and timer 33. The control unit 30 controls the washing machine 1 according to the user's instructions (i.e., settings) input by the operation unit 4. The control unit 30 also receives signals from the water level detection unit 18 and the rotation speed reading device 19. The control unit 30 supplies power to each part of the washing machine 1 (motor 7 and loading device 10, etc., which will be described later) via a drive circuit 35. The control unit 30 controls the display on the setting display unit 50 of the operation unit 4 and controls the activation of the buzzer 17. The control unit 30 also controls the tank light-emitting unit 80 and turns on or off each light-emitting unit, which will be described later, individually.

[0024] As shown in Figure 2, the outer tub 5a has a bottomed cylindrical shape. The outer tub 5a is, for example, a tub made of resin. The outer tub 5a is elastically suspended from the housing 2 by a plurality (for example, four) of suspension rods having vibration damping devices. The outer tub 5a is configured to be supplied with a washing liquid through a water supply channel provided in the housing 2, and to be able to discharge the washing liquid from the outer tub 5a through a drainage channel provided in the housing 2. In this specification, "washing liquid" means a liquid corresponding to each process of the laundry, such as the washing process and the rinsing process. Therefore, in the washing process, the washing liquid may be a liquid containing a liquid agent such as detergent, and in the rinsing process, the washing liquid may be water or a liquid containing a liquid agent such as fabric softener.

[0025] The inner tub 5b has a bottomed cylindrical shape. The inner tub 5b is smaller than the outer tub 5a and is positioned inside the outer tub 5a, coaxially with the outer tub 5a. The inner tub 5b is rotatable around a rotation axis extending in the Z direction. The inner tub 5b is, for example, a metal tub. The inner tub 5b is a tub for washing or dewatering laundry placed inside it. Multiple through holes are formed on the inner circumferential surface of the inner tub 5b. This allows laundry liquid to flow between the outer tub 5a and the inner tub 5b. A rotating blade 6, also called a pulsator, is rotatably mounted at the bottom of the inner tub 5b.

[0026] A motor 7 (see Figure 4) is housed inside the casing 2 to rotate the inner tank 5b and the rotor blade 6. The motor 7 constitutes part of the drive unit located at the bottom of the outer tank 5a. The motor 7 generates power (torque) to drive the inner tank 5b and the rotor blade 6, causing them to rotate. For example, in the washing and rinsing processes, the motor 7 transmits the power only to the rotor blade 6 to rotate only the rotor blade 6, and in the dewatering process, it transmits the power to the rotor blade 6 and the inner tank 5b to rotate the rotor blade 6 and the inner tank 5b together.

[0027] The washing machine 1 is equipped with a dispensing device 10 for dispensing processing liquid into the inner tub 5b. As shown in Figure 2, the dispensing device 10 is incorporated (mounted) in the upper rear part of the housing 2 such that the front part of the dispensing device 10 is exposed when the top lid 3 is open. Figure 5 is a piping diagram of the dispensing device 10. The dispensing device 10 includes, for example, three water supply pipes, namely the main water supply pipe 11 and auxiliary water supply pipes 12 and 13, which are connected to a water supply source 9 (such as a tap for tap water) outside the washing machine 1. The main water supply pipe 11 is provided with, for example, a first water supply valve V1 and an injection nozzle 14. The auxiliary water supply pipes 12 and 13 are provided with a second water supply valve V2 and a third water supply valve V3, respectively. The first water supply valve V1, the second water supply valve V2, and the third water supply valve V3 are each known automatic valves. The opening and closing operations of the first water supply valve V1, the second water supply valve V2, and the third water supply valve V3 are controlled by the control unit 30. The supply device 10 is also called an automatic supply device.

[0028] The dispensing device 10 is equipped with a water inlet 25 for dispensing the processing liquid into the inner tank 5b. The water inlet 25 is positioned above the inner tank 5b. Inside the water inlet 25 is a manual container 24 for manually dispensing liquid or powdered agents. The manual container 24 includes, for example, a detergent container 26 and a fabric softener container 27 connected to the auxiliary water supply pipe 12 and auxiliary water supply pipe 13, respectively. The dispensing device 10 also has a bath water pump 28 for drawing water from the bathtub. Priming water is supplied to the bath water pump 28 through piping branched from the auxiliary water supply pipe 12. A drain pipe 29 is connected to the bottom of the outer tank 5a, and a drain valve Vb is provided in the drain pipe 29. The opening and closing operation of the drain valve Vb is controlled by the control unit 30.

[0029] In this embodiment, the dispensing device 10 includes, for example, three processing liquid supply units connected to the main water supply pipe 11: a detergent supply unit 20A, a custom agent supply unit 20B, and a fabric softener supply unit 20C. The detergent supply unit 20A has a detergent tank (detergent storage unit) 21A for storing detergent and a first pump unit 22A. The custom agent supply unit 20B has a custom agent tank (custom agent storage unit) 21B for storing custom agent and a second pump unit 22B. The fabric softener supply unit 20C has a fabric softener tank (fabric softener storage unit) 21C for storing fabric softener and a third pump unit 22C. In other words, the dispensing device 10 has multiple storage units for storing multiple liquid agents. In "multiple liquid agents," "multiple" means that there are multiple "types" of liquid agents. The detergent tank 21A, the custom agent tank 21B, and the fabric softener tank 21C are each detachable by the user when the washing machine 1 is stopped and the top lid 3 is open. The first pump unit 22A, the second pump unit 22B, and the third pump unit 22C each inject the various liquid agents into the main water supply pipe 11 and mix them with water. Through this operation, the dispensing device 10 dispenses the processing liquid containing the various liquid agents into the inner tank 5b.

[0030] The dispensing device 10 is controlled by the control unit 30 and dispenses at least one of the detergent, custom agent, and fabric softener at a predetermined timing, according to the operating course selected by the user and the user's settings for the liquids to be used. In other words, the control unit 30 controls the dispensing device 10 so that the liquids to be used are dispensed at a predetermined timing. The liquids to be used are the liquids to be dispensed in the selected operating course and are stored in either the detergent tank 21A, the custom agent tank 21B, or the fabric softener tank 21C. According to the selected operating course and the user's settings in the operation unit 4, the dispensing device 10 controls at least one of the first pump unit 22A, the second pump unit 22B, and the third pump unit 22C at a predetermined timing to dispense the processing liquid containing the liquids to be used into the inner tank 5b.

[0031] In this specification, the terms "use" and "input" are used with respect to any type of liquid agent, and these terms are synonymous. "Use" is a term based on the user's perspective, while "input" is a term based on the washing machine 1 (input device 10 and control unit 30).

[0032] Referring to Figures 3, 4, and 6, the setting of the liquid agent by the operation unit 4 and the display control in the operation unit 4 according to the liquid agent setting will be explained. As shown in Figure 3, the operation unit 4 has a setting display unit 50 for setting the liquid agent by the user. The setting display unit 50 accepts a single press operation of a button (or key) by the user and displays the setting content. The setting operation using the setting display unit 50 is input to the control unit 30 shown in Figure 4 and stored in the memory 32 at the timing when the start button 42 is pressed. A known non-volatile memory is used as the memory 32. The control unit 30 controls the setting display unit 50 and causes the setting content to be displayed on the setting display unit 50.

[0033] As shown in Figure 6, the setting display unit 50 has a detergent setting unit 51 for setting the detergent, a custom agent setting unit 52 for setting the custom agent, and a fabric softener setting unit 53 for setting the fabric softener. In the washing machine 1, bleach, fabric softener, detergent, and delicate laundry detergent can be used as custom agents, i.e., custom agents stored in the custom agent tank 21B. Therefore, the types of custom agents that can be selected in the custom agent setting unit 52 include bleach, fabric softener, detergent, and delicate laundry detergent. Note that the above is just an example, and other liquid agents may be used as custom agents. In that case, the types of custom agents that can be selected in the custom agent setting unit 52 will also include those other liquid agents.

[0034] The custom agent tank 21B is an optional setting tank that allows the user to select the desired liquid agent. The presence of the custom agent tank 21B enables the automatic dispensing of liquid agents other than general detergents and fabric softeners, such as bleach or delicate laundry detergent. Furthermore, the presence of the custom agent tank 21B allows for the automatic dispensing of a different type of detergent than that stored in the detergent tank 21A, and a different type of fabric softener than that stored in the fabric softener tank 21C.

[0035] The detergent setting unit 51 is an operating unit for setting the amount of detergent to be dispensed from the detergent tank 21A. The fabric softener setting unit 53 is an operating unit for setting the amount of fabric softener to be dispensed from the fabric softener tank 21C. The custom agent setting unit 52 is an operating unit for setting the type of custom agent to be dispensed from the custom agent tank 21B and the amount of the selected custom agent to be dispensed. The custom agent setting unit 52 includes a first selection unit 54, which is an operating unit for selecting the type of custom agent, and a second selection unit 55, which is an operating unit for selecting the amount of the custom agent to be dispensed from the custom agent selected in the first selection unit 54. Each of these operating units is a button (or key) that can sequentially change the set value (setting level) with a single press.

[0036] The control unit 30 controls the detergent supply unit 20A to dispense detergent from the detergent tank 21A during an operation course that includes a detergent dispensing step, except when a detergent has been selected in the custom agent setting unit 52 and the amount of detergent to be dispensed has been set (when the detergent is set as the liquid agent to be used as a custom agent). In this case, the detergent in the detergent tank 21A corresponds to the liquid agent to be used. The detergent tank 21A is pre-filled with the type of detergent desired by the user and stored therein.

[0037] The control unit 30 controls the fabric softener supply unit 20C to dispense fabric softener from the fabric softener tank 21C during the operation course that includes the fabric softener dispensing process, except when fabric softener has been selected in the custom agent setting unit 52 and the amount of fabric softener to be dispensed has been set (when fabric softener is set as the liquid agent to be used as a custom agent). In this case, the fabric softener in the fabric softener tank 21C corresponds to the liquid agent to be used. The fabric softener tank 21C is pre-filled and stored with the type of fabric softener desired by the user.

[0038] The control unit 30 controls the custom agent supply unit 20B to dispense the liquid agent, i.e., the custom agent, from the custom agent tank 21B in the following cases during the operation course which includes the liquid agent dispensing process (custom agent dispensing conditions). • When a detergent is selected in the custom agent setting unit 52 and the amount of detergent to be added is set (when the detergent is set as the liquid agent to be used as a custom agent) • When fabric softener is selected in the custom agent setting unit 52 and the amount of fabric softener to be added is set (when fabric softener is set as the liquid agent to be used as a custom agent) • When bleach is selected in the custom agent setting unit 52 and the amount of bleach to be added is set (when bleach is set as the liquid agent to be used) • When delicate laundry detergent is selected in the custom agent setting unit 52 and the amount of delicate laundry detergent to be added is set (when delicate laundry detergent is set as the liquid agent to be used) However, unless the type of custom agent has been selected (set) by the first selection unit 54, the operation by the second selection unit 55 will not be accepted.

[0039] Depending on the settings described above, the custom agent tank 21B is pre-filled and stored with the type of detergent, fabric softener, bleach, or delicate laundry detergent desired by the user.

[0040] The control unit 30 controls the display in the setting display unit 50 to correspond to each of the above settings. The control unit 30 displays in the setting display unit 50 that at least one liquid agent is to be added. The setting display unit 50 includes a detergent amount display unit 61, a custom agent setting display unit 62, and a fabric softener amount display unit 63. The custom agent setting display unit 62 can display the type of custom agent selected in the custom agent setting unit 52 and the amount of the selected custom agent to be added. The custom agent setting display unit 62 includes a custom agent type display unit 64 and a custom agent amount display unit 65.

[0041] As shown in Figure 6, the detergent amount display unit 61 includes three display sections: "More," "Standard," and "Less," corresponding to the selectable detergent amounts. These display sections light up (switch) sequentially with a single press of the detergent setting unit 51. The custom agent type display unit 64 includes four display sections: "Bleach," "Fabric softener," "Detergent," and "Delicate," corresponding to the liquid agents that can be selected as custom agents. These display sections light up (switch) sequentially with a single press of the first selection unit 54. The custom agent amount display unit 65 includes three display sections: "More," "Standard," and "Less," corresponding to the selectable custom agent amounts. These display sections light up (switch) sequentially with a single press of the second selection unit 55. The fabric softener amount display unit 63 includes three display sections: "More," "Standard," and "Less," corresponding to the selectable fabric softener amounts. These display sections light up (switch) sequentially with a single press of the fabric softener setting unit 53. Each of these display sections has a built-in light-emitting element such as an LED, and the lighting and extinguishing of each light-emitting element is controlled by the control unit 30.

[0042] The illuminated display portion in each of the above display units corresponds to the setting operation (setting content) stored in the memory 32 of the control unit 30. The control unit 30 adjusts the operating time of each pump during dispensing, corresponding to the "more," "standard," and "less" amounts of liquid dispensed.

[0043] The control unit 30 displays on the setting display unit 50 that at least one liquid agent will be dispensed, according to the operating course selected by the user and the type and amount of liquid agent set by the user. For example, when the user presses the power button 41 (see Figure 3) to turn on the washing machine 1, the control unit 30 displays that the liquid agent will be dispensed based on the setting of the previous liquid agent used, which is stored in the memory 32. For this purpose, the memory 32 stores the setting of the liquid agent used even after the washing machine 1 is turned off.

[0044] Furthermore, a course selection button 43 is provided on the control panel 4 so that the user can select and change any desired washing course. Memory 32 retains the setting of the washing course even after the washing machine 1 is turned off. Memory 32 stores the setting of the detergent used and the washing course separately. When a special washing course, such as the "delicate wash course" (see Figure 11), is selected and the operation is completed and the power is turned off, that course is not stored in memory. When the power is turned on again, a stored course (such as the standard course that is always used) is selected, and the previously stored setting of the detergent used is recalled when the "standard course" is selected. Then, when the course selection button 43 is pressed and the "delicate wash course" is selected, the previously stored setting of the detergent used is recalled when the "delicate wash course" is selected. In this way, memory 32 stores the setting of the detergent used and the washing course in a linked (corresponding) manner.

[0045] As shown in Figure 6, the setting display unit 50 includes a detergent dispensing display unit 71, a custom dispensing display unit 72, and a fabric softener dispensing display unit 73. The detergent dispensing display unit 71 is located below the detergent amount display unit 61 and between the detergent amount display unit 61 and the detergent setting unit 51. The custom dispensing display unit 72 is located below the custom agent amount display unit 65 and between the custom agent amount display unit 65 and the second selection unit 55. The fabric softener dispensing display unit 73 is located below the fabric softener amount display unit 63 and between the fabric softener amount display unit 63 and the fabric softener setting unit 53. Each of the detergent dispensing display unit 71, the custom dispensing display unit 72, and the fabric softener dispensing display unit 73 is decorated with a specific design (also called a pictogram, etc.). Each of the detergent dispensing display unit 71, the custom dispensing display unit 72, and the fabric softener dispensing display unit 73 has a built-in light-emitting unit such as an LED, and the lighting and extinguishing of each light-emitting unit is controlled by the control unit 30.

[0046] The control unit 30 illuminates either the detergent dispensing indicator 71 or the custom dispensing indicator 72 based on predetermined conditions when the selected operating course includes a detergent dispensing step. The control unit 30 illuminates either the fabric softener dispensing indicator 73 or the custom dispensing indicator 72 based on predetermined conditions when the selected operating course includes a fabric softener dispensing step. The control unit 30 illuminates the custom dispensing indicator 72 based on predetermined conditions when the selected operating course includes a bleach or delicate laundry detergent dispensing step. The illumination of any of the detergent dispensing indicator 71, fabric softener dispensing indicator 73, and custom dispensing indicator 72 means that the corresponding liquid from either the detergent tank 21A, fabric softener tank 21C, or custom agent tank 21B is scheduled to be dispensed as the liquid to be used in the operating course that starts from that point. The predetermined conditions are the detergent dispensing conditions, fabric softener dispensing conditions, and custom agent dispensing conditions described above, and specific examples will be explained later in this specification with reference to Figure 7 and subsequent figures.

[0047] Furthermore, certain types of liquid agents (such as delicate laundry detergent, detergent, or bleach) cannot be accepted in specific operating courses selected by the course selection button 43 (see Figure 11). If a specific type of liquid agent cannot be accepted in a particular operating course, the single-press operation of the custom agent setting unit 52 (i.e., the first selection unit 54 and the second selection unit 55) is invalid, and the user cannot input the usage setting (input setting) for that liquid agent.

[0048] The washing machine 1 of this embodiment is equipped with a mechanism to improve the visibility of the liquid used in the dispensing device 10, which is set via the setting display unit 50. Specific examples of display control in the setting display unit 50 and light emission control in the light-emitting units of each tank will be described with reference to Figures 2, 4, 6, and 7 onward.

[0049] As shown in Figures 2 and 4, the dispensing device 10 has a tank light-emitting unit 80 that selectively illuminates the detergent tank 21A, the custom additive tank 21B, and the fabric softener tank 21C, respectively. Specifically, the dispensing device 10 has a first light-emitting unit 81A provided in the detergent tank 21A, a second light-emitting unit 81B provided in the custom additive tank 21B, and a third light-emitting unit 81C provided in the fabric softener tank 21C. Each of the first light-emitting unit 81A, the second light-emitting unit 81B, and the third light-emitting unit 81C is, for example, an LED mounted inside each tank. Each tank is provided with a transparent window so that the amount of liquid inside can be seen, and the light emitted from the LED is reflected inside the tank and illuminates the transparent window. The lighting and extinguishing of the first light-emitting unit 81A, the second light-emitting unit 81B, and the third light-emitting unit 81C are controlled by the control unit 30.

[0050] As shown in Figures 2 and 6, the arrangement of each light-emitting unit in the dispensing device 10 corresponds to the arrangement of each setting unit in the setting display unit 50. That is, as shown in Figure 2, in the dispensing device 10, the detergent tank 21A is located on the left, the fabric softener tank 21C is located on the right, and the custom agent tank 21B is located between them (in the center). As shown in Figure 6, in the setting display unit 50, the detergent amount display unit 61 and the detergent dispensing display unit 71 are located on the left, the fabric softener amount display unit 63 and the fabric softener dispensing display unit 73 are located on the right, and the custom agent setting display unit 62 and the custom agent dispensing display unit 72 are located between them (in the center). In addition, three tanks are located directly below (below) the setting display unit 50 (see Figure 2). This uniformity of arrangement and positional relationship enhances visibility (see also Figure 7, etc.).

[0051] As shown in Figures 7(a) to 7(d), the control unit 30 displays in the setting display unit 50 that the liquid agent to be used is being added, and in conjunction with this display, illuminates a light-emitting unit provided in the tank that stores the liquid agent among the multiple tanks. More specifically, the control unit 30 displays in the setting display unit 50 that the liquid agent to be used is being added, and simultaneously with this display, illuminates a light-emitting unit provided in the tank that stores the liquid agent among the multiple tanks. The control unit 30 continues the display of the liquid agent to be added in the setting display unit 50 and the illumination of the light-emitting unit provided in the tank for a certain period of time, for example, after the start button 42 is pressed. The duration of this display and illumination is, for example, 1 minute. The duration of the display and illumination is not limited to this and can be changed as appropriate.

[0052] Let's explain some specific examples. For example, in the examples shown in Figures 7(a) and 7(b), the detergent amount display unit 61 is lit up with "extra," and the detergent dispensing display unit 71 is lit up. Simultaneously with this illumination, the first light-emitting unit 81A (see Figure 2) in the detergent tank 21A is lit up. This allows the user to quickly understand that the detergent in the detergent tank 21A is scheduled for use (to be dispensed) before changing the settings. In addition, the custom agent type display unit 64 is lit up with "detergent," indicating that "detergent" is selected, but since no selection has been made by the second selection unit 55, the custom dispensing display unit 72 is not lit, and the second light-emitting unit 81B in the custom agent tank 21B is also not lit up.

[0053] Subsequently, as shown in Figure 7(c), the user operates the second selection unit 55, and "Standard" lights up on the custom agent quantity display unit 65, and the custom dispensing display unit 72 lights up. Then, as shown in Figure 7(d), the second light-emitting unit 81B in the custom agent tank 21B lights up in conjunction with the lighting up of the custom dispensing display unit 72. This allows the user to quickly understand that the detergent in the custom agent tank 21B is scheduled for use (to be dispensed) after the setting change.

[0054] Thus, the detergent settings are determined based on the settings made later in the detergent setting unit 51 and the custom agent setting unit 52. The control unit 30 then stores these settings. Furthermore, the control unit 30 does not recognize the custom agent as a liquid to be used and does not light up the custom agent input indicator unit 72 if only the type of custom agent is selected in the first selection unit 54. The control unit 30 lights up the custom agent input indicator unit 72 in the setting display unit 50 only when both the type of custom agent is selected in the first selection unit 54 and the amount of custom agent to be used is selected in the second selection unit 55. In other words, the control unit 30 displays that the custom agent will be added as a liquid to be used only when these two selection operations have been performed.

[0055] As shown in Figures 8(a) to 8(d), the same applies if, conversely, the use setting (dispensing setting) for the custom agent is made before the setting change, and then the detergent setting unit 51 is operated by the user. Regarding the detergent setting, the setting is made based on the setting operation made later between the detergent setting unit 51 and the custom agent setting unit 52. As shown in Figure 8(c), the detergent setting unit 51 is operated by the user, the detergent amount display unit 61 lights up as "extra", and the detergent dispensing display unit 71 lights up. Then, as shown in Figure 8(d), the first light-emitting unit 81A in the detergent tank 21A lights up in conjunction with the illumination of the detergent dispensing display unit 71. This allows the user to quickly understand that the detergent in the detergent tank 21A is scheduled for use (dispensing) after the setting change.

[0056] When the detergent amount is set in the detergent setting unit 51, the control unit 30 turns off the display of the amount to be added in the custom agent amount display unit 65 and the display indicating that a custom agent is being added as a liquid agent in the custom agent addition display unit 72 (turning off the custom agent amount display unit 65 and the custom agent addition display unit 72). At this time, the selection (setting) of the type of custom agent in the custom agent type display unit 64 is maintained, and "Detergent" remains lit. In conjunction with the setting of the detergent amount in the detergent setting unit 51, the control unit 30 cancels the setting of the amount to be added for the custom agent and the setting for adding that custom agent.

[0057] The example of fabric softener will also be explained. For example, in the examples shown in Figures 9(a) and 9(b), the fabric softener amount display unit 63 is lit up with "extra," and the fabric softener dispensing display unit 73 is lit up. Simultaneously with this illumination, the third light-emitting unit 81C (see Figure 2) in the fabric softener tank 21C is illuminated. This allows the user to quickly understand that the detergent in the fabric softener tank 21C is scheduled for use (to be dispensed) before changing the settings. Although the custom agent type display unit 64 is lit up with "fabric softener," indicating that "fabric softener" is selected, the custom dispensing display unit 72 is not lit, and the second light-emitting unit 81B in the custom agent tank 21B is also not illuminated, as no selection has been made by the second selection unit 55.

[0058] Subsequently, as shown in Figure 9(c), the user operates the second selection unit 55, and "Standard" lights up on the custom dosage display unit 65, and the custom dispensing display unit 72 lights up. Then, as shown in Figure 9(d), the second light-emitting unit 81B in the custom agent tank 21B lights up in conjunction with the illumination of the custom dispensing display unit 72. This allows the user to quickly understand that the fabric softener in the custom agent tank 21B is scheduled for use (to be dispensed) after the setting change.

[0059] In this way, the setting for the fabric softener is also determined based on the setting operation performed later in the fabric softener setting unit 53 and the custom softener setting unit 52. The control unit 30 then stores this setting.

[0060] As shown in Figures 10(a) to 10(d), the same applies if, conversely, the use setting (dispensing setting) for custom softeners is made before the setting change, and then the softener setting unit 53 is operated by the user. Regarding the softener setting, the setting is made based on the setting operation made later between the softener setting unit 53 and the custom softener setting unit 52. As shown in Figure 10(c), the softener setting unit 53 is operated by the user, the softener amount display unit 63 lights up as "extra", and the softener dispensing display unit 73 lights up. Then, as shown in Figure 10(d), the third light-emitting unit 81C in the softener tank 21C lights up in conjunction with the lighting of the softener dispensing display unit 73. This allows the user to quickly understand that the softener in the softener tank 21C is scheduled for use (dispensing) after the setting change.

[0061] When the amount of fabric softener is set in the fabric softener setting unit 53, the control unit 30 turns off the display of the amount to be added in the custom agent amount display unit 65 and the display indicating that a custom agent is being added as a liquid agent in the custom agent addition display unit 72 (turning off the custom agent amount display unit 65 and the custom agent addition display unit 72). At this time, the selection (setting) of the type of custom agent in the custom agent type display unit 64 is maintained, and "Fabric Softener" remains lit. In conjunction with the setting of the amount of fabric softener in the fabric softener setting unit 53, the control unit 30 cancels the setting of the amount of custom agent to be added and the setting for adding that custom agent.

[0062] Although not shown in the diagram, there are other display control examples besides those described above. The setting display unit 50 can display the type and amount of custom agent selected in the custom agent setting unit 52 in the custom agent type display unit 64 and the custom agent quantity display unit 65. When the type of custom agent is changed in the first selection unit 54, the control unit 30 turns off the display of the amount to be added in the custom agent quantity display unit 65 and the display indicating that the custom agent as a liquid agent to be added in the custom agent addition display unit 72 (turns off the custom agent quantity display unit 65 and the custom agent addition display unit 72). The control unit 30 also turns off the illumination of the second light-emitting unit 81B in the custom agent tank 21B in conjunction with the turning off of the display (end of display). With the change in the type of custom agent, the control unit 30 cancels the setting of the amount to be added and the setting for adding that custom agent.

[0063] As described above, the washing machine 1 of this embodiment is provided with a light-emitting section in each of the multiple tanks. When the setting display unit 50 indicates that a liquid to be used is to be added, the control unit 30 causes the light-emitting section of the tank corresponding to the liquid to be used to illuminate in conjunction with the display. Therefore, the user can visually confirm (confirm) both the display on the setting display unit 50 and the illumination of the tank corresponding to the liquid to be used. Normally, a specific type of liquid is poured into the tank by the user. The user can easily see the tank containing the liquid to be used (i.e., the liquid to be added in the current operating course). For example, if the user intends to use delicate laundry detergent and has stored delicate laundry detergent in the custom detergent tank 21B, but the custom detergent tank 21B does not light up and remains dark, the user will realize that the setting is incorrect. Alternatively, even if an operating course that uses bleach is selected and the settings on the setting display unit 50 are made appropriately, there is still a possibility that bleach has been forgotten to be added to the custom detergent tank 21B. Even in that case, the custom agent tank 21B is illuminated, prompting the user to pour bleach into the custom agent tank 21B. Correction of inappropriate settings can be performed whether the top lid 3 is open or closed. Replenishing necessary liquids can be done with the top lid 3 open, or by opening the top lid 3 if it is closed. The illumination of the tank is visible through the transparent section 3c even when the top lid 3 is closed. The washing machine 1 is equipped with a dispensing device 10 that allows the use of multiple liquids, and the visibility of the liquid settings can be improved. For example, even if a usage error occurs due to some factor, the user can immediately notice the error and proceed with the correction as described above.

[0064] As shown in Figure 11, depending on the selected washing course, there are specifications that prevent the setting of adding certain liquids (making them unselectable). In the table shown in Figure 11, a "○" indicates that it is selectable, and a "×" indicates that it is unselectable. For example, the control unit 30 does not accept the setting to add "delicate laundry detergent" in the standard course, quick course, etc. However, in washing machine 1, the control unit 30 does accept the setting to add "delicate laundry detergent" in the custom course and wrinkle reduction course, etc.

[0065] The custom agent setting unit 52 includes a first selection unit 54 for selecting the type of custom agent and a second selection unit 55 for selecting the amount of custom agent to be added. This allows the user to perform laundry according to their preferences and purposes (for example, a cycle using a predetermined liquid agent) by selecting the type of custom agent in the first selection unit 54. Furthermore, the user can perform laundry according to their preferences and purposes (for example, laundry with a predetermined concentration of custom agent) by selecting the amount of custom agent to be added in the second selection unit 55. The unit offers excellent operability in each selection operation.

[0066] Furthermore, the control unit 30 displays a message on the setting display unit 50 indicating that the custom agent will be dispensed as a liquid agent, provided that both the selection of the type of custom agent in the first selection unit 54 and the selection of the amount of custom agent to be dispensed in the second selection unit 55 have been made. As a result, the setting display unit 50 will only display a message indicating that the custom agent will be dispensed once the type of custom agent and the amount to be dispensed have been appropriately set. In other words, the custom agent will not actually be dispensed unless both settings are made. This prevents errors in setting the custom agent. The user can intuitively operate the second selection unit 55 (button operation, etc.) to complete the setting of the custom agent.

[0067] Furthermore, when the type of custom agent is changed in the first selection unit 54, the control unit 30 turns off the display of the input amount in the setting display unit 50, as well as the display indicating that the custom agent will be added as the liquid agent to be used. Following the change in the type of custom agent, the control unit 30 cancels the input amount setting and the setting for adding that custom agent. This allows the user to be prompted to set the input amount, preventing the changed custom agent from being added at the input amount based on the previous setting (incorrect amount).

[0068] Regarding detergent settings, the settings are determined based on the setting operation performed later between the detergent setting unit 51 and the custom agent setting unit 52. For example, if a first type of detergent is poured into detergent tank 21A and a second type of detergent is poured into custom agent tank 21B, the detergent to be dispensed (the detergent to be used) is set based on the setting operation performed later between the detergent setting unit 51 and the custom agent setting unit 52. Therefore, duplicate detergent dispensing is avoided. The illumination of either tank prevents the use of the wrong detergent (for example, dispensing a type of detergent different from the user's intention).

[0069] Regarding the setting of fabric softener, the setting may be made based on the setting operation performed later between the fabric softener setting unit 53 and the custom softener setting unit 52. For example, the first type of fabric softener is poured into the fabric softener tank 21C and the second type of fabric softener is poured into the custom softener tank 21B. In this case, the fabric softener to be added (the fabric softener to be used) is set based on the setting operation performed later between the fabric softener setting unit 53 and the custom softener setting unit 52. Therefore, duplicate dispensing of fabric softener can be avoided. The illumination of either tank can prevent the use of the wrong type of fabric softener (for example, dispensing a type of fabric softener different from the user's intention).

[0070] The control unit 30 stores the settings for the liquid used even after the washing machine 1 is turned off. When the washing machine 1 is turned on, the setting display unit 50 displays that the liquid will be dispensed based on the stored liquid settings, and in conjunction with this display, the light-emitting unit in the tank that stores the liquid illuminates. The liquid usage conditions from the previous operation are stored, so there is no need to set the same liquid usage conditions again. Therefore, convenience for the next use is improved.

[0071] The control unit 30 displays in the setting display unit 50 that the liquid agent to be used has been added, and simultaneously with this display, the light-emitting unit provided in the tank that stores the liquid agent to be used illuminates. As a result, the user can visually confirm (confirm) both the display in the setting display unit and the illumination of the storage unit corresponding to the liquid agent to be used, thus further improving the visibility described above.

[0072] Although embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, the light emission mode of each light-emitting part provided in the tank is not limited to continuous illumination, but may be other modes such as flashing.

[0073] The second selection unit 55 may be omitted. By selecting the type of custom agent in the first selection unit 54, the user can perform laundry according to their preferences and purpose (for example, a washing course using a predetermined liquid agent). The amount of custom agent to be added may be automatically set by the control unit 30.

[0074] The first selection unit 54 may be omitted. The user can select the amount of custom agent to be added in the second selection unit 55 to perform laundry according to their preferences and purpose (for example, laundry with a predetermined concentration of custom agent). In this case, the type of custom agent stored in the custom agent tank 21B is fixed, but the user can change the amount added as they see fit.

[0075] Two custom agent storage compartments may be provided. The fabric softener tank may be omitted. There may be only two tanks in total, or there may be four tanks in total.

[0076] The "display of liquid used" in the setting display unit 50 is not limited to the illumination of the detergent dispensing display unit 71, the custom dispensing display unit 72, and the fabric softener dispensing display unit 73. For example, the detergent setting unit 51, the custom dispensing setting unit 52, and the fabric softener dispensing display unit 73 may be provided with light-emitting units that illuminate. Alternatively, the setting display unit 50 may have a separate display, and the control unit 30 may display messages on the display such as "The detergent tank on the far left will be used," "The fabric softener tank on the far right will be used," or "The fabric softener tank in the center will be used."

[0077] In the above embodiment, the control unit 30 displayed a message on the setting display unit 50 indicating that the liquid agent to be used is being added, and simultaneously with this display, the light-emitting unit provided in the tank that stores the liquid agent was illuminated. However, the control unit 30 may also display a message on the setting display unit 50 indicating that the liquid agent to be used is being added, and then, with a slight delay from this display, illuminate the light-emitting unit provided in the tank that stores the liquid agent. The control unit 30 may maintain the display on the setting display unit 50 and, with a time delay, illuminate the light-emitting unit provided in the tank that stores the liquid agent, or it may turn off the display on the setting display unit 50 and then illuminate the light-emitting unit provided in the tank that stores the liquid agent. In this case as well, the user can continuously see (confirm) the display on the setting display unit 50 and the illumination of the tank corresponding to the liquid agent to be used.

[0078] In the above embodiment, the case where the first light-emitting unit 81A, the second light-emitting unit 81B, and the third light-emitting unit 81C are each LED mounted inside each tank was described. However, the first light-emitting unit 81A, the second light-emitting unit 81B, and the third light-emitting unit 81C may each be LEDs mounted on the outside (surface) of each tank. Alternatively, the first light-emitting unit 81A, the second light-emitting unit 81B, and the third light-emitting unit 81C may each be LEDs mounted above or below each tank. The installation method is not limited as long as it is clear which tank each light-emitting unit corresponds to. If each light-emitting unit is provided outside each tank, the transparent window in each tank may be omitted.

[0079] The present invention is not limited to top-loading washing machines, but may also be applied to front-loading washing machines. [Explanation of Symbols]
