[0006] When the washing water is supplied to the laundry contained in the drum and the drum rotates due to the motor, the contaminants attached to the laundry can be removed by the friction between the laundry and the drum and the washing water.

[0007] A laundry detergent dispenser has a detergent dispensing function to improve washing results. Here, laundry detergent refers to substances that enhance washing performance, such as fabric softener, textile bleach, etc. Laundry detergent can be in powder form or liquid form.

[0008] On the other hand, published document KR10-2018-0090003A1 discloses a laundry detergent supply device included in a garment handling apparatus. In this garment handling apparatus, garments can be washed by supplying laundry detergent stored in the detergent supply device to the interior of the outer tub.

[0009] The laundry detergent supply device may include a plurality of detergent dispensers for storing laundry detergent, and the user may arbitrarily store various types of laundry detergent into the plurality of detergent dispensers and wash the clothes.

[0010] Therefore, in this technical field, it is a very important issue to improve the maintainability and manageability of laundry detergent containers that store various laundry detergents by effectively using the various laundry detergents stored in a plurality of such detergent containers to perform the washing program for clothes. Summary of the Invention

[0011] The problem to be solved

[0012] The problem to be solved by this application is to provide a garment handling device that can prevent the detergent from solidifying when the use of a detergent dispenser that can store various types of detergent changes.

[0013] In addition, the problem to be solved by this application may also be to provide a garment handling device that can clean the detergent dispenser when the type of detergent stored in the detergent dispenser changes.

[0014] In addition, the problem to be solved by this application may also be to provide a clothing handling device that can prevent the previously stored laundry detergent from mixing with the changed laundry detergent when the type of laundry detergent stored in the detergent dispenser changes.

[0015] In addition, the problem to be solved by this application may also be to provide a garment handling device that can clean the flow path connected to the detergent box when the type of detergent stored in the detergent box changes.

[0016] In addition, the problem to be solved by this application may also be to provide a clothing treatment device that allows a user to confirm whether the detergent dispenser needs to be cleaned and to choose whether to clean it or not.

[0017] Technical solutions to the problem

[0018] To solve the above problems, in a garment handling apparatus according to an embodiment of the present invention, when the laundry detergent stored in the first detergent container or the second detergent container is scheduled to change to a different type of laundry detergent, the control unit performs a residual detergent discharge process by controlling the laundry detergent pump to discharge the remaining laundry detergent in the first detergent container or the second detergent container corresponding to the predetermined laundry detergent change state.

[0019] Additionally, one embodiment of the garment handling apparatus of the present invention includes: a housing; an outer tub disposed inside the housing, the outer tub containing water; a drum rotatably disposed inside the outer tub, the drum containing garments; a detergent supply device connected to the outer tub, supplying detergent to the outer tub by driving a detergent pump connected to a first detergent container and a second detergent container for storing detergent; and a control unit that, in the event of a predetermined detergent change state corresponding to a predetermined change of detergent stored in the first detergent container or the second detergent container to a different type of detergent, performs a residual detergent discharge process by driving the detergent pump to discharge the remaining detergent in the first detergent container or the second detergent container corresponding to the predetermined detergent change state.

[0020] The control unit can determine whether the operation signal input by the user through the operation unit set in the cabinet or the user-carrying communication terminal is equivalent to a change in the predetermined state of the laundry detergent.

[0021] The detergent pump may include a first detergent pump connected to the first detergent dispenser and a second detergent pump connected to the second detergent dispenser. The control unit can independently control the first detergent pump and the second detergent pump to perform the remaining detergent discharge process of the first detergent dispenser and the second detergent dispenser, respectively.

[0022] The laundry detergent may include at least one of a detergent that removes contaminants from clothing and a fabric softener that ensures the softness of clothing. When the laundry detergent stored in the first laundry detergent box or the second laundry detergent box is scheduled to change between the detergent and the fabric softener, the control unit may determine that it is equivalent to a predetermined state of laundry detergent change.

[0023] The control unit can control the detergent supply device to selectively perform any one of the following modes: a single detergent mode in which detergent is supplied to the outer tub from either the first detergent dispenser or the second detergent dispenser; a combined detergent mode in which detergent is supplied to the outer tub from both the first detergent dispenser and the second detergent dispenser; and a fabric softener mode in which detergent is supplied to the outer tub from either the first detergent dispenser or the second detergent dispenser while fabric softener is supplied to the outer tub from the other detergent dispenser.

[0024] The control unit can execute any one of the single detergent mode, the compound detergent mode, and the fabric softener mode based on the operation signal input by the user through the operation unit set in the cabinet or the user-portable communication terminal.

[0025] When the fabric softener mode is executed after the single detergent mode or the compound detergent mode is executed, or when the single detergent mode or the compound detergent mode is executed after the fabric softener mode is executed, the control unit may determine that it is equivalent to a predetermined state of the detergent change.

[0026] When an operation signal is input via the operation unit located in the housing or a user-portable communication terminal to change the laundry detergent stored in the first or second laundry detergent box from the detergent to the fabric softener, or to change the laundry detergent to the detergent, the control unit can determine that this is equivalent to a predetermined state of laundry detergent change.

[0027] In cases where the laundry detergent has changed to a predetermined state, the control unit can execute a cleaning request process by requesting the user to select whether to proceed with the discharge of the remaining laundry detergent through a notification unit located in the cabinet or a user-portable communication terminal.

[0028] When the remaining detergent discharge process is determined to be performed during the washing request process, the control unit may execute a water injection request process that requests water to be injected into the first detergent dispenser or the second detergent dispenser via the notification unit or the communication terminal.

[0029] It may also include a remaining amount sensing unit that senses the water level in the first detergent dispenser or the second detergent dispenser. The control unit can perform a water filling confirmation process based on the measurement value of the remaining amount sensing unit to determine whether water has been added to the first detergent dispenser or the second detergent dispenser according to the water filling request process.

[0030] When the water filling confirmation process determines that water has been injected into the first detergent dispenser or the second detergent dispenser, the control unit can execute the remaining detergent discharge process.

[0031] When the remaining detergent discharge process ends, the control unit can request the user to supply detergent to the first or second detergent box after the remaining detergent discharge process has ended through a notification unit located in the box or a user-portable communication terminal.

[0032] The control unit can control the operation of the detergent pump for a preset time during the discharge of the remaining detergent, and the control unit can also control the water supply unit to supply water to the outer tub during the discharge of the remaining detergent.

[0115] The water supply valve 140 can be configured to connect to the water supply pipe 35 of the outer tub to restrict the flow of water supplied to the outer tub 30. The water supply valve 140 can also be connected to the water supply pipe 35 of the outer tub via the detergent supply device 100.

[0116] For example, water supplied from an external water source and passing through the water supply valve 140 can be delivered to the water supply unit 110 via the water supply hose 142. Water supplied to the detergent supply device 100 via the water supply unit 110 can be delivered to the interior of the outer tub 30 via the outer tub water supply pipe 35. However, the outer tub water supply pipe 35 can also be separated from the water supply hose 142 and directly connected to the water supply valve 140, so that water from the water supply valve 140 can also be directly delivered to the outer tub water supply pipe 35.

[0117] On the other hand, the detergent storage unit 120 may include the aforementioned detergent storage space. In one embodiment of the present invention, the detergent storage unit 120 may include a detergent box 122 for storing detergent, and the internal space of the detergent box 122 may correspond to at least a portion of the detergent storage space.

[0118] The detergent storage unit 120 may be configured to be detachable from the detergent supply device 100. For example, the detergent storage unit 120 may be configured to be detachable from the aforementioned water supply unit 110 and the housing 130 described later and led out to the outside of the housing 10.

[0119] Users can store laundry detergent in the laundry detergent storage unit 120 in the following manner: extend the laundry detergent storage unit 120 to the outside of the housing 10 and supply laundry detergent to the laundry detergent box 122, and then bring the laundry detergent storage unit 120 back into the housing 10.

[0120] However, as mentioned above, in one embodiment of the present invention, the form of the detergent storage unit 120 is not necessarily limited to that described above. For example, it may be configured such that at least a portion of the detergent supply device 100 is disposed outside the housing 10, and the detergent box 122 is combined with the top panel or front panel, etc., outside the housing 10.

[0121] On the other hand, in one embodiment of the present invention, the housing 130 may be disposed inside the box 10 and configured to accommodate the detergent storage unit 120 introduced into the box 10. The water supply unit 110 may be configured to supply water to the detergent storage unit 120 accommodated in the housing 130 and to the interior of the housing 130.

[0122] The housing 130 may include a receiving space for accommodating the detergent storage unit 120, one side of which is open, and the water supply unit 110 may be configured on said open side.

[0123] Therefore, in one embodiment of the present invention, the detergent storage unit 120 is defined by the water supply unit 110 and the housing 130, and the detergent storage unit 120 can be inserted into the housing space from the front to the rear of the housing space that is open to the front.

[0124] In one embodiment of the present invention, water supplied to the water supply unit 110 via the water supply valve 140 and the water supply hose 142 can be discharged from the water supply unit 110 into the detergent storage unit 120 and the housing 130.

[0125] Water supplied from water supply unit 110 to detergent storage unit 120 can be discharged to the outside of detergent storage unit 120 along with detergent in detergent storage unit 120. The water and detergent discharged from detergent storage unit 120 can be transferred to the receiving space of receiving housing 130.

[0126] Water discharged from the water supply unit 110 and detergent discharged from the detergent storage unit 120 can be discharged together to the outside through the drain hole 131 of the housing 130. The water and detergent discharged through the drain hole 131 can be transferred to the outer tub water supply pipe 35 and supplied to the interior of the outer tub 30.

[0127] The drain hole 131 of the housing 130 can also be connected to the interior of the outer tub 30 via an additional water supply pipe separately provided relative to the outer tub water supply pipe 35. For example, water and detergent discharged from the drain hole 131 can also flow along a detergent water supply pipe additionally provided relative to the outer tub water supply pipe 35 and extending from the drain hole 131, and be supplied to the interior of the outer tub 30 through the outer tub opening or a hole formed on the outer side of the outer tub 30.

[0128] On the other hand, Figure 5 According to an embodiment of the present invention, a detergent opening 12 formed in the housing 10 is shown. Figure 6 A detergent storage unit 120 is shown, which is introduced into the housing 10 through the detergent opening 12.

[0129] As mentioned above, in one embodiment of the present invention, the detergent storage unit 120 may include a detergent box 122, and the detergent storage unit 120 may be configured to be detachable from the detergent supply device 100 and led out to the outside of the housing 10.

[0130] The housing 10 may include a detergent opening 12 that is penetrated by the detergent storage unit 120. For example... Figure 5 As shown, the detergent opening 12 can be located on the front panel at a position separated from the garment opening 15, but it is not necessarily limited to this.

[0131] The laundry detergent storage unit 120 may include a storage frame 121 and a handle 1211. The laundry detergent dispenser 122 may be attached to the storage frame 121 and introduced into the housing 10 together with the storage frame 121 or extended to the outside of the housing 10.

[0132] The handle 1211 can be located at the front end of the storage frame 121. The handle 1211 is configured to protrude to the outside of the housing 10 when the detergent storage unit 120 is fully introduced into the housing 10, so that it can be held by the user.

[0133] like Figure 5 and Figure 6 As shown, when the detergent opening 12 is provided on the front panel of the housing 10, the detergent storage unit 120 can be inserted into the housing 10 through the detergent opening 12 on the front panel, and the handle 1211 can be located outside the housing 10, thus forming the front appearance of the garment handling device 1 together with the front panel.

[0134] on the other hand, Figure 7 This is a top view of a laundry detergent storage unit 120 according to an embodiment of the present invention. Figure 8 This is a diagram showing the state in which the detergent box 122 is separated from the detergent storage unit 120 according to an embodiment of the present invention.

[0135] As mentioned above, the laundry detergent storage unit 120 may include a storage frame 121 and a laundry detergent box 122. The storage frame 121 may include the aforementioned handle portion 1211, and a connection space may be formed inside the storage frame 121 for the laundry detergent box 122 to be connected.

[0136] Additionally, the storage frame 121 may include a detergent-containing area 1213, the interior of which is capable of storing detergent independently of the detergent dispenser 122. The detergent-containing area 1213 may correspond to a portion of the aforementioned detergent storage space. That is, in one embodiment of the invention, the detergent storage unit 120 can store detergent in a detergent storage space comprising the interior space of the detergent dispenser 122 and the detergent-containing area 1213.

[0137] In one embodiment of the present invention, the detergent storage unit 120 may include a plurality of detergent dispensers 122. For example, as Figure 7 and Figure 8 As shown, in one embodiment of the present invention, the detergent dispenser 122 may include a first detergent dispenser 1221 and a second detergent dispenser 1222. However, the number of detergent dispensers 122 can vary as needed.

[0138] The first detergent dispenser 1221 and the second detergent dispenser 1222 can be configured independently to store different detergents. Additionally, the aforementioned detergent-containing area 1213 can be separated from the first detergent dispenser 1221 and the second detergent dispenser 1222 to store a different detergent.

[0139] For example, liquid detergent can be stored inside the detergent dispenser 122, which ensures water tightness, while powdered detergent can be stored in the detergent holding area 1213, which allows for easy refilling. However, this is not a limitation, and the type and form of detergent stored in the detergent dispenser 122 and the detergent holding area 1213 can be varied.

[0140] on the other hand, Figure 9 The diagram shows the disassembled state of a laundry detergent dispenser 122 according to an embodiment of the present invention. (Refer to...) Figure 9 In one embodiment of the present invention, the detergent dispenser 122 may include a storage body 123 and a storage cover 124.

[0141] A storage space for storing laundry detergent can be formed inside the storage body 123, and the top surface of the storage body 123 is open so that the storage body 123 can be exposed upwards. The storage cover 124 can be combined with the storage body 123 to cover the open top surface of the storage body 123.

[0142] However, it is not necessary to limit it to this; the storage body 123 and the storage cover 124 can also be formed as a single unit to create a sealed storage space.

[0143] On the other hand, a detergent cap 125 may be provided on the storage cover 124. The storage cover 124 may include an opening, and the detergent cap 125 may be detachably attached to the storage cover 124 to cover the opening.

[0144] In one embodiment of the present invention, an opening communicating with the storage space inside the detergent box 122 is formed in the storage cover 124, and the opening is covered by a detergent cap 125 that is detachably attached to the storage cover 124. Thus, the user can easily supply detergent to the inside of the detergent box 122 through the opening of the storage cover 124 without having to separate the detergent box 122 from the storage frame 121 or the storage cover 124 from the storage body 123.

[0145] on the other hand, Figure 10 A residual amount sensor 126 is shown installed in the detergent dispenser 122. (See reference) Figure 9 and Figure 10 An embodiment of the present invention may include a remaining amount sensing unit 126 capable of sensing the remaining amount of detergent in the first detergent dispenser 1221 and the second detergent dispenser 1222.

[0146] The remaining amount sensor 126 can be disposed in the storage frame 121, the housing 130, or the detergent dispenser 122. Figure 10 According to an embodiment of the present invention, a remaining amount sensing unit 126 is provided on the back of the storage body 123 of the detergent dispenser 122.

[0147] In one embodiment of the present invention, the remaining amount sensing unit 126 may be configured to form at least a portion of the back side of the storage body 123 and include a contact portion capable of sensing the remaining amount of laundry detergent by contact with the detergent.

[0148] For example, a plurality of contact parts can be provided and configured to be energized to each other when in contact with laundry detergent, thereby enabling the measurement of the remaining amount of laundry detergent by whether or not the contact parts are energized.

[0149] The remaining amount sensing unit 126 can be provided in each of the first detergent box 1221 and the second detergent box 1222 to sense the remaining amount of detergent in each of the first detergent box 1221 and the second detergent box 1222. The remaining amount sensing unit 126 can be connected to the control unit 200 and send the sensing signal for the remaining amount to the control unit 200.

[0150] On the other hand, the remaining amount sensing unit 126 may include a sensing body 1261 and a sensing terminal 1262, and the sensing body 1261 may form at least a part of the storage body 123. The sensing body 1261 may be provided with the aforementioned contact portion, which may be configured to be exposed to the storage space and in contact with the laundry detergent.

[0151] The sensing terminal 1262 can be electrically or signal-connected to the control unit 200 by connecting to wires or the like. The electrical signal generated by the contact between the contact part and the detergent can be transmitted from the sensing terminal 1262 to the control unit 200 via wires or the like. The control unit 200 can determine the remaining amount of detergent in the detergent dispenser 122 by receiving the electrical signal transmitted via the sensing terminal 1262.

[0152] However, in one embodiment of the present invention, the type, location and shape of the remaining amount sensing unit 126 are not limited to those described above, and can be provided in various types and locations as needed.

[0153] on the other hand, Figure 11 A housing 130 according to an embodiment of the present invention is shown. (Refer to...) Figure 11 In one embodiment of the present invention, a detergent box sensing unit 127 may be provided to sense whether the first detergent box 1221 and the second detergent box 1222 are inserted into the housing 130.

[0154] In one embodiment of the present invention, the first detergent dispenser 1221 and the second detergent dispenser 1222 can be detachably disposed on the detergent supply device 100. That is, the first detergent dispenser 1221 and the second detergent dispenser 1222 can be detachably attached to the detergent supply device 100.

[0155] The way the first detergent dispenser 1221 and the second detergent dispenser 1222 are combined with the detergent supply device 100 can be varied. For example, as mentioned above, the first detergent dispenser 1221 and the second detergent dispenser 1222 can be combined with the storage frame 121 and introduced into the interior of the housing 10 or led out to the exterior of the housing 10.

[0156] Additionally, the detergent supply device 100 may be configured such that at least a portion of it protrudes outside the housing 10, and the first detergent box 1221 and the second detergent box 1222 may be detachably attached to the externally protruding portion of the detergent supply device 100.

[0157] For ease of explanation, unless otherwise specified, the following description will be based on the scenario where the first detergent dispenser 1221 and the second detergent dispenser 1222 are introduced into the housing 10 or led out to the outside of the housing 10 so as to be detachable from the detergent supply device 100, in a state of being integrated with the storage frame 121 of the detergent storage unit 120.

[0158] The detergent dispenser sensing unit 127 can be configured to sense whether the first detergent dispenser 1221 and the second detergent dispenser 1222 are attached to the detergent supply device 100, such as the housing 130. The detergent dispenser sensing unit 127 can be disposed in the storage frame 121 of the detergent storage unit 120 or in the housing 130.

[0159] exist Figure 11 The present invention schematically illustrates a detergent dispenser sensing unit 127 disposed on the back side of a housing 130, according to an embodiment of the present invention. (See also...) Figure 11 The detergent dispenser sensing unit 127 is disposed in the housing 130 and senses whether the detergent storage unit 120 is inserted, thereby sensing whether the first detergent dispenser 1221 and the second detergent dispenser 1222 are installed.

[0160] For example, the detergent dispenser sensing unit 127 can be configured to generate an electrical signal when it is pressurized or in contact with the storage frame 121 housed inside the housing 130. Since the first detergent dispenser 1221 and the second detergent dispenser 1222 are inserted into the housing 10 together with the storage frame 121, the sensing signal of the detergent dispenser sensing unit 127 can indicate that the first detergent dispenser 1221 and the second detergent dispenser 1222 are installed in the detergent supply device 100.

[0161] The detergent dispenser sensing unit 127 can be electrically or signal-connected to the control unit 200. The control unit 200 can determine whether the first detergent dispenser 1221 and the second detergent dispenser 1222 are contained by the electrical signal of the detergent dispenser sensing unit 127.

[0162] on the other hand, Figure 12 A detergent pump 132 and a detergent hose 133 are shown disposed within a housing 130. (See reference...) Figure 11 and Figure 12 An embodiment of the present invention may include a detergent pump 132 for discharging detergent stored in a detergent dispenser 122.

[0163] As mentioned above, the detergent dispenser 122 may include a first detergent dispenser 1221 and a second detergent dispenser 1222, and the detergent pump 132 may include a first detergent pump 1321 connected to the first detergent dispenser 1221 and a second detergent pump 1322 connected to the second detergent dispenser 1222.

[0164] The detergent pump 132 may be disposed in the housing 130. As mentioned above, in one embodiment of the present invention, the detergent storage unit 120 may be introduced into the housing 10 through the detergent opening 12 disposed on the front panel, and the detergent pump 132 may be disposed on the back of the housing 130 and connected to the detergent box 122 of the detergent storage unit 120 which is completely disposed in the housing 130.

[0165] The detergent pump 132 can be configured to discharge detergent from inside the detergent dispenser 122. For example, liquid detergent can be stored inside the detergent dispenser 122, and the detergent pump 132 can discharge the liquid detergent from inside the detergent dispenser 122 to the outside of the detergent dispenser 122.

[0166] Laundry detergent pumped from detergent dispenser 122 via detergent pump 132 can flow through detergent hose 133 connected to detergent pump 132. The laundry detergent pumped from detergent dispenser 122 via detergent pump 132 can ultimately be supplied to the interior of outer tub 30.

[0167] The way laundry detergent is supplied to the interior of the outer tub 30 via the detergent pump 132 can be varied. For example, the detergent hose 133 can be connected from the detergent pump 132 to the outer tub 30 or the outer tub water supply pipe 35, and the laundry detergent flowing from the detergent dispenser 122 via the detergent pump 132 can be supplied to the interior of the outer tub 30 or the outer tub water supply pipe 35 along the detergent hose 133.

[0168] Additionally, the detergent hose 133 extending from the detergent pump 132 can be configured to communicate with the interior of the housing 130. Thus, detergent flowing from the detergent dispenser 122 can flow along the detergent hose 133 and be discharged into the housing 130, whereby the detergent, along with water supplied from the water supply unit 110, can flow into the outer tub 30 through the drain hole 131 of the housing 130.

[0169] Additionally, the detergent hose 133 extending from the detergent pump 132 can be connected to the water supply unit 110. Therefore, the detergent flowing from the detergent dispenser 122 can be supplied to the water supply unit 110, and the water supply unit 110 can be configured to discharge water and detergent together into the housing 130. The water and detergent inside the housing 130 can be transferred to the outer tub 30 through the drain hole 131 as described above.

[0170] exist Figure 12According to an embodiment of the present invention, a detergent pump 132 is shown attached from the rear of the housing 130, and a detergent hose 133 extending from the detergent pump 132 and connected to the water supply unit 110 is shown. When the detergent pump 132 is operating, the detergent stored in the detergent dispenser 122 can be moved to the water supply unit 110 through the detergent pump 132 and the detergent hose 133.

[0171] on the other hand, Figure 13 The present invention illustrates a laundry detergent modification process according to an embodiment of the present invention.

[0172] In cases where the type of laundry detergent stored in the first detergent dispenser 1221 or the second detergent dispenser 1222 is changed, i.e. when the purpose of the detergent dispenser changes, it is sometimes necessary to clean the detergent dispenser 122 before supplying new laundry detergent to it.

[0173] For example, as described above, various types of laundry detergent can be stored in the first detergent dispenser 1221 and the second detergent dispenser 1222. These may include detergents that remove contaminants, fabric softeners that improve the softness of fibers, and so on.

[0174] However, when detergent and fabric softener are mixed, they may clump together. When detergent clumps, it may not dissolve well in water and may form clumps that block the flow path for detergent movement. This can prevent the detergent dispenser from supplying detergent smoothly.

[0175] To prevent the problems described above, in the case of a planned change of the detergent stored in the first detergent box 1221 or the second detergent box 1222, that is, in the case where a particular detergent box 122 corresponds to a predetermined state of detergent change (S100), the detergent box 122 can be cleaned to prevent the previously stored detergent from mixing with the new detergent to be stored.

[0176] That is, the process of completely draining the detergent contained in the corresponding detergent dispenser 122 or cleaning the interior with water can be performed before supplying new detergent. Cleaning the detergent dispenser may refer to draining all the liquid contained inside by operating the detergent pump 132. Alternatively, it may include rinsing the detergent dispenser 122 and the detergent hose 133 by operating the detergent pump 132 to drain the water additionally supplied to the detergent dispenser 122.

[0177] On the other hand, refer to Figure 13In a garment handling apparatus according to an embodiment of the present invention, when a predetermined state of detergent change (S100) is reached, which corresponds to a predetermined change in the detergent stored in the first detergent container 1221 or the second detergent container 1222, the control unit 200 can drive the detergent pump 132 to perform a residual detergent discharge process (S600) that discharges the remaining detergent in the first detergent container 1221 or the second detergent container 1222, which corresponds to the predetermined state of detergent change (S100).

[0178] Specifically, when the first detergent dispenser 1221 is in the detergent change predetermined state (S100), the control unit 200 can operate the first detergent pump 1321 to discharge the remaining detergent stored in the first detergent dispenser 1221. Similarly, when the second detergent dispenser 1222 is in the detergent change predetermined state (S100), the control unit 200 can operate the second detergent pump 1322 to discharge the remaining detergent stored in the second detergent dispenser 1222.

[0179] In addition, when the first detergent dispenser 1221 and the second detergent dispenser 1222 are in the detergent change predetermined state (S100), the control unit 200 discharges the remaining detergent stored in the first detergent dispenser 1221 and the second detergent dispenser 1222 by operating the first detergent pump 1321 and the second detergent pump 1322.

[0180] In other words, the control unit 200 can independently control the first detergent pump 1321 and the second detergent pump 1322, and the control unit 200 can independently execute the residual detergent discharge process of each of the first detergent box 1221 and the second detergent box 1222 (S600).

[0181] On the other hand, the control unit 200 can determine whether the operation signal input through the operation unit 50 or the user-portable communication terminal 300 corresponds to a predetermined state of laundry detergent change (S100). That is, when a specific signal is input by the user, the control unit 200 can identify that the first laundry detergent box 1221 or the second laundry detergent box 1222 corresponds to a predetermined state of laundry detergent change (S100).

[0182] Figure 14 An example of a specific signal identified by the control unit 200 as a predetermined state of laundry detergent change (S100) is shown. The specific signal identified by the control unit 200 as a predetermined state of laundry detergent change (S100) is not limited to the figures and can include various situations.

[0183] For example, when the laundry detergent stored in the first detergent dispenser 1221 is intended to be changed between detergent and fabric softener, the control unit 200 can determine that the first detergent dispenser 1221 is equivalent to a laundry detergent change intended state (S100). The control unit 200 can determine whether the second detergent dispenser 1222 is equivalent to a laundry detergent change intended state in the same way as the first detergent dispenser 1221 (S100).

[0184] More specifically, when fabric softener is to be stored instead of detergent in the first detergent dispenser 1221, which previously contained detergent, the control unit 200 can determine that the first detergent dispenser is in a detergent change pre-set state (S100). When fabric softener was previously stored and the stored detergent is to be changed to detergent, the control unit 200 can make the same determination.

[0185] When a signal indicating a change in the detergent supply mode is input, or a signal indicating a change in the detergent stored in the first detergent container 1221 or the second detergent container 1222 is input, the control unit 200 can recognize it as equivalent to a detergent change predetermined state (S100).

[0186] Figure 15 An example of a laundry detergent supply pattern is shown.

[0187] Reference Figure 15 The laundry detergent supply mode M1 may include a single-detergent mode M11, a compound detergent mode M12, and a fabric softener mode M13. The laundry detergent supply mode M1 is not limited to the type shown in the diagram and may include a variety of modes. However, for ease of explanation, the following description focuses on the case where the laundry detergent supply mode M1 includes all three modes.

[0188] Single detergent mode M11 can refer to a mode in which detergent is supplied to the outer tub 30 from either the first detergent dispenser 1221 or the second detergent dispenser 1222 during the operation of the garment handling device. That is, detergent can be stored in both the first detergent dispenser 1221 and the second detergent dispenser 1222. Although the types of detergent stored can be different, they can be equivalent to detergents used to remove stains from laundry. In other words, the same type of first detergent can be stored in both the first detergent dispenser 1221 and the second detergent dispenser 1222, or the first detergent can be stored in the first detergent dispenser 1221 and the second detergent can be stored in the second detergent dispenser. However, the situation where detergent is supplied from only one of the first and second detergent dispensers during the detergent supply process can be defined as single detergent mode M11.

[0189] Additionally, the detergent supply mode M1 may include a compound detergent mode M12. Compound detergent mode M12 can refer to a mode in which detergent is supplied to the outer tub 30 from both the first detergent dispenser 1221 and the second detergent dispenser 1222. The first detergent dispenser 1221 and the second detergent dispenser 1222 may store detergents of different types or the same type. However, the case where both the first detergent dispenser 1221 and the second detergent dispenser 1222 store detergent and detergent is supplied from both during the detergent supply process can be defined as compound detergent mode M12.

[0190] Additionally, the detergent supply mode M1 may include a fabric softener mode M13. Fabric softener mode M13 can refer to a mode in which detergent is supplied to the outer tub 30 from either the first detergent dispenser 1221 or the second detergent dispenser 1222, while fabric softener is supplied to the outer tub 30 from the other. That is, in fabric softener mode M13, either the first detergent dispenser 1221 or the second detergent dispenser may contain detergent, while the other may contain fabric softener.

[0191] The control unit 200 can selectively execute any one of the following modes: single detergent mode M11, compound detergent mode M12, and fabric softener mode M13. The control unit 200 can execute any one of these modes based on an operation signal input by the user. The user's operation signal can be input via the operation unit 50 or the communication terminal 300.

[0192] When selecting the single-detergent mode M11 and the multi-detergent mode M12, detergent should be stored in both the first detergent dispenser 1221 and the second detergent dispenser 1222. Although the types of detergent stored may be different, all detergents should be stored.

[0193] However, when the fabric softener mode M13 is selected, fabric softener should be stored in either the first detergent dispenser 1221 or the second detergent dispenser 1222.

[0194] Therefore, when a single detergent mode M11 or a compound detergent mode M12 has been previously executed and the detergent supply mode M1 is subsequently changed to a fabric softener mode M13, either the first detergent dispenser 1221 or the second detergent dispenser 1222 may have originally contained detergent but is subsequently to store fabric softener. Consequently, the detergent and fabric softener may mix inside the detergent dispenser 122. Therefore, to prevent the mixing of detergent and fabric softener, a residual detergent discharge process (S600) can be performed.

[0195] That is, when the fabric softener mode M13 is executed after the single detergent mode M11 or the compound detergent mode M12 is executed, the control unit 200 can determine that either the first detergent box 1221 or the second detergent box 1222 is equivalent to the detergent change predetermined state (S100).

[0196] Furthermore, if the single detergent mode M11 or the compound detergent mode M12 is executed after the fabric softener mode M13 is executed, the control unit 200 may determine that either the first detergent dispenser 1221 or the second detergent dispenser 1222 corresponds to the predetermined state of the detergent change (S100).

[0197] In the manner described above, the control unit 200 can determine that the first detergent dispenser 1221 or the second detergent dispenser 1222 is equivalent to the detergent change predetermined state when the detergent supply mode changes (S110) (S100).

[0198] In addition, when the storage detergent in the first detergent box 1221 or the second detergent box 1222 is changed directly (S120), the control unit 200 can also determine that the first detergent box 1221 or the second detergent box 1222 is equivalent to the detergent change predetermined state (S100).

[0199] Users can input a signal to change the detergent stored in the first detergent dispenser 1221 or the second detergent dispenser 1222 by operating the operation unit 50 or the communication terminal 300. For example, when a user inputs a signal to change the detergent stored in the first detergent dispenser 1221, the control unit 200 can determine that the first detergent dispenser 1221 is in a predetermined detergent change state (S100).

[0200] In particular, when a signal is input to change the detergent and fabric softener of the laundry detergent stored in the first detergent box 1221 or the second detergent box 1222, the control unit 200 can determine that the first detergent box 1221 or the second detergent box 1222 storing the laundry detergent that has changed between detergent and fabric softener is equivalent to a laundry detergent change predetermined state (S100).

[0201] Specifically, when a user inputs a signal to change the detergent stored in the first detergent dispenser 1221 from detergent to fabric softener, the control unit 200 can determine that the first detergent dispenser 1221 is in a detergent change predetermined state (S100). This also applies when fabric softener was previously stored but the stored detergent is subsequently changed to detergent.

[0202] Refer again Figure 13In the case of a predetermined state equivalent to a change in laundry detergent (S100), the control unit 200 can execute a cleaning request process (S200) by requesting the selection of whether to perform the remaining laundry detergent discharge process (S600) through the notification unit 60 or the communication terminal 300.

[0203] Even when the detergent dispenser 122 has a pre-defined detergent change, the user can skip the remaining detergent discharge process (S600) and directly start the washing process of the garment handling device as needed. Automatically performing the remaining detergent discharge process (S600) without considering the user's needs may reduce usability. Therefore, the control unit 200 can execute a wash request process (S200) to allow the user to select whether to perform the remaining detergent discharge process (S600).

[0204] When the user decides not to perform washing according to the washing request process (S200), the detergent addition process described later (S700) can be performed.

[0205] Furthermore, when the system determines whether to proceed with cleaning in the cleaning request process (S200) and decides to proceed with the residual detergent discharge process (S600), the control unit 200 may execute the water injection process (S500). The water injection process (S500) may include a water injection request process (S510) requesting water injection and a water injection confirmation process (S520) where the user confirms whether water has been injected.

[0206] The control unit 200 can execute a water injection request process (S510) by requesting water to be injected into the first detergent dispenser 1221 or the second detergent dispenser 1222 through the notification unit 60 or the communication terminal 300.

[0207] Specifically, the user can select to proceed with the remaining detergent discharge process (S600) by inputting an operation signal through the operation unit 50 or the communication terminal 300 according to the washing request process (S200). When it is determined to proceed with the remaining detergent discharge process (S600), the control unit 200 can request water to be added to the detergent dispenser 122, which is in the detergent change predetermined state (S100).

[0208] The notification unit 60 or the communication terminal 300 may display a phrase such as "Please add water to the first detergent dispenser". Alternatively, the notification unit 60 corresponding to "first detergent dispenser" may repeatedly flash at preset time intervals to request water to be added.

[0209] During the water injection request process (S510), the user may be asked in various ways to inject water into the detergent dispenser 122, which is about to undergo the residual detergent discharge process (S600).

[0210] The water injection request process (S510) may not be a mandatory process. The control unit 200 may also skip the water injection request process (S510) and directly execute the remaining detergent discharge process (S600) by running the detergent pump 132.

[0211] On the other hand, as described above, the laundry handling apparatus of one embodiment of the present invention may further include a remaining amount sensing unit 126. The remaining amount sensing unit 126 may be respectively disposed in the first detergent dispenser 1221 or the second detergent dispenser 1222 and sense the water level of the first detergent dispenser 1221 and the second detergent dispenser 1222.

[0212] The control unit 200 can determine whether water has been injected into the first detergent dispenser 1221 or the second detergent dispenser 1222 according to the water injection request process (S510) based on the measurement value of the remaining amount sensing unit 126. The process of determining whether water has been injected according to the water injection request process (S510) can be defined as the water injection confirmation process (S520).

[0213] During the water filling confirmation process (S520), when the remaining water level sensor 126 detects that water has been injected above a preset level, the control unit 200 determines that water has been injected into the detergent dispenser 122. When water is confirmed to have been injected into the detergent dispenser 122 during the water filling confirmation process (S520), the control unit 200 can activate the detergent pump 132 connected to the detergent dispenser 122.

[0214] When the detergent pump 132 operates, the detergent residue inside the detergent dispenser 122 and the injected water can be discharged together. As the injected water is discharged, washing can proceed into the connected detergent hose 133. The control unit 200 can operate the detergent pump 132 until all the injected water is discharged. However, regarding the basis for the control unit 200 to control the operation of the detergent pump 132, in addition to the water level inside the detergent dispenser 122, the operation of the detergent pump 132 can also be interrupted based on the operating time.

[0215] On the other hand, when the remaining detergent discharge process (S600) ends, the control unit 200 may request the user to add new detergent to the detergent dispenser 122 where the remaining detergent discharge process has ended. The control unit 200 may include a detergent addition process (S700) that requests supply to the first detergent dispenser 1221 or the second detergent dispenser 1222 where the remaining detergent discharge process (S600) has ended via the notification unit 60 or the communication terminal 300, and determines whether detergent has been supplied.

[0216] That is, the laundry detergent dispensing process (S700) may include: a laundry detergent dispensing request process, which requests the user to dispensing new laundry detergent into the laundry detergent dispenser 122 after the remaining laundry detergent dispensing process (S600) has ended, via the notification unit 60 or the communication terminal 300; and a laundry detergent dispensing confirmation process, which confirms whether the user has dispensed new laundry detergent into the laundry detergent dispenser 122 that was requested to be dispensed.

[0217] Similar to the water filling confirmation process (S520), the detergent addition confirmation process can be performed by the remaining amount sensing unit 126. The control unit 200 can use the measurement value of the remaining amount sensing unit 126 to confirm whether the detergent has been added to the detergent dispenser 122 after the remaining detergent discharge process (S600) has ended.

[0218] On the other hand, the operation mode of the residual detergent discharge process (S600) will be described. In the residual detergent discharge process (S600), the control unit 200 can control the detergent pump 132 to operate for a preset time.

[0219] That is, during the residual detergent discharge process (S600), the control unit 200 can end the residual detergent discharge process (S600) regardless of the water level of the liquid contained inside the detergent dispenser 122, taking only the running time of the detergent pump 132 into account. When the detergent pump 132 runs for a sufficient time, it has the effect of not only discharging the detergent remaining inside the detergent dispenser 122, but also fully discharging the detergent remaining in the detergent hose 133.

[0220] The operating time of the detergent pump 132 can be set to various settings. Preferably, the operating time is determined based on the capacity of the detergent dispenser 122. When the capacity of the detergent dispenser 122 is large, the preset operating time of the detergent pump 132 can be increased.

[0221] However, during the residual detergent discharge process (S600), the operation mode of the detergent pump 132 does not simply depend on the operating time. The control unit 200 can consider the measurement value of the residual amount sensing unit 126 and the operating time of the detergent pump 132 to perform the residual detergent discharge process (S600).

[0222] For example, even if the operating time of the detergent pump 132 exceeds a preset time, the detergent pump 132 can continue to operate when the water level value measured by the remaining amount sensing unit 126 is higher than the preset water level value. That is, the remaining detergent discharge process can be performed by taking into account the measurement value of the remaining amount sensing unit 126 and the operating time of the detergent pump 132 (S600).

[0223] On the other hand, during the remaining detergent discharge process (S600), the control unit can control the water supply unit 110 to supply water to the outer tub 30. As described above, the detergent discharged from the detergent dispenser 122 by the detergent pump 132 can move to the water supply unit 110 through the detergent hose 133. At this time, the control unit 200 can control the water supply unit 110 to supply water together with the discharged detergent, so that the discharged detergent can flow more smoothly.

[0224] That is, during the residual detergent discharge process (S600), the control unit 200 can control the water supply valve 140 to supply water to the water supply unit 110. The water and detergent discharged from the water supply unit 110 can be supplied to the outer tub through the housing 130.

[0225] Figure 16 This diagram illustrates the process of selecting the detergent dispenser to be cleaned via the control unit.

[0226] Reference Figure 13 and Figure 16 When it is determined that the remaining detergent discharge process is to be carried out (S600), the control unit 200 can execute a detergent box selection process (S400) based on the user's operation signal input through the operation unit 50 or the communication terminal 300 to select the detergent box 122 to be carried out the remaining detergent discharge process (S600).

[0227] The user can select whether to perform the residual detergent discharge process by operating the cleaning button A1 (S600). If the user pressurizes the cleaning button A1 for a preset time or more, the control unit 200 can determine that the residual detergent discharge process should be performed (S600).

[0228] When the user selects the detergent dispenser to proceed with the remaining detergent discharge process (S600) by pressing the cleaning button A1, the user can select the detergent dispenser to proceed with the remaining detergent discharge process (S600) by pressing the selection buttons B1 and B2 on the control panel.

[0229] When both the first button B1 and the second button B2 are operated, both the first detergent dispenser 1221 and the second detergent dispenser 1222 can be selected (S410). When the first button B1 is operated without operating the second button B2, the first detergent dispenser can be selected (S420). When the second button B2 is operated without operating the first button B1, the second detergent dispenser can be selected (S430).

[0230] The control unit 200 can control the lights corresponding to each detergent dispenser to illuminate, allowing the user to confirm which detergent dispenser has been selected. When both the first and second detergent dispensers are selected (S410), both the first button B1 and the second button B2 may be illuminated. When the first detergent dispenser is selected (S420), only the first button B1 may be illuminated. Similarly, when the second detergent dispenser is selected (S430), only the second button B2 may be illuminated.

[0231] A specific operational example can be given, which can be performed as follows. When the user initiates the process of discharging remaining detergent (S600), firstly, the user can enter the detergent dispenser selection process by operating the washing button A1. If the user wishes to change the detergent stored in the first detergent dispenser 1221 from detergent to fabric softener, the user can operate the first button B1. When the user completes the first detergent dispenser selection by operating the first button B1 (S410), the first button B1 is illuminated, and the user can recognize that the first detergent dispenser 1221 has been selected. Afterwards, the control unit 200 can execute the process of discharging remaining detergent from the first detergent dispenser 1221 by controlling the first detergent pump 1321 connected to the first detergent dispenser 1221 (S600).

[0232] The above operation can also be performed when the detergent supply mode changes (S110) or the stored detergent changes (S120). When the detergent supply mode changes from a single detergent mode to a fabric softener mode, the user can change one of the detergents stored in the first detergent container 1221 or the second detergent container 1222 from detergent to fabric softener. At this time, the detergent container whose stored detergent has been changed can be selected, and the remaining detergent discharge process is performed on that detergent container (S600).

[0233] Although specific embodiments of the present invention have been illustrated and described, it is self-evident to those skilled in the art that the present invention can be modified and varied in various ways without departing from the technical concept of the present invention as set forth in the claims.
