[147] In some implementations, the detergent supply device 200 may include a remaining amount detection unit 260, and through it it is possible to detect whether or not the detergent stored in each detergent storage container 221, 222 is insufficient. For example, the remaining amount detection unit 260 may include a sensor, an electrode, or an electrical circuit. The details of this will be described later.

[148] FIG. 8A is a perspective view illustrating an example of a body 210 of the detergent supply device 200, FIG. 8B is a perspective view illustrating an exemplary state in which the first detergent storage container 221 and the second detergent storage container 222 are attached to the storage container frame 210d, and FIG. wherein the first detergent storage container and the second detergent storage container are installed in the storage container frame.

[149] Laundry detergent pumps 231, 232 to enable the transfer of various laundry detergents, respectively, may be provided in the rear portion of the housing 210.

[150] Detergent stored in each of the detergent storage containers 221, 222 can be discharged through an outlet provided in the rear surface portion of each detergent storage container 221, 222 through the action of the detergent pumps 231, 232 for washing. The discharged detergent is then introduced into the body 210, mixed with the wash water introduced into the body, and finally supplied to the tub.

[151] The laundry detergent pumps 231, 232 serve to generate a transfer force for generating detergent movement, and may include a first laundry detergent pump 231 and a second laundry detergent pump 232.

[152] The first laundry detergent suction tube 231a and the second laundry detergent suction tube 232b may protrude from the inner portion of the rear surface of the case 210, respectively.

[153] The first laundry detergent suction tube 231a and the second laundry detergent suction tube 232b may be connected to the pump receiving portions 221a, 222b protruding from the rear portions of the detergent storage containers 221, 222, respectively.

[154] The laundry detergent stored in the first detergent storage container 221 is discharged to the first laundry detergent inlet 211a through the first laundry detergent suction tube 231a.

[155] Similarly, the laundry detergent stored in the second detergent storage container 222 is discharged to the second laundry detergent inlet 211b through the second laundry detergent suction tube 232b.

[156] In some implementations, the pump receiving portions 221a, 222a may protrude from the rear portions of the detergent storage containers 221, 222 toward the laundry detergent pumps 231, 232. The laundry detergent stored in the detergent storage container 221, 222 can move towards the laundry detergent pumps 231, 232 after passing through the pump receiving portions 221a, 222a. Then, the laundry detergent may pass through the first laundry detergent passage 211 and the second laundry detergent passage 212 to be discharged into the housing 210.

[157] The first laundry detergent pump 231 sucks the laundry detergent stored in the first detergent storage container 221 through the first laundry detergent suction tube 231a, and then discharges the detergent into the first detergent inlet 211a for washing through the first inlet pipe 241 for detergent for washing. The laundry detergent discharged through the first laundry detergent inlet 211a can move through the first laundry detergent passage 211 .

[158] Similarly, the second laundry detergent pump 232 sucks the detergent stored in the second detergent storage container 222 through the second detergent suction tube 231b, and then discharges the detergent into the second detergent inlet 211b through the second inlet tube 242 for detergent. The laundry detergent discharged through the second laundry detergent inlet 211b can be moved through the second laundry detergent passage 212 .

[159] Here, since the first laundry detergent passage 211 and the second laundry detergent passage 212 are separated from each other by a separating wall 213 formed on the lower surface of the housing 210 inserted therebetween, each detergent moving through the first passage 211 for laundry detergent and the second laundry detergent passage 212 can be prevented from mixing with each other.

[160] In some implementations, when the wash water is supplied to the wash water supply portion 251d provided on both sides of the wash water dispenser 251 through the third wash water inlet portion 251c'' (see FIG. 6) , the wash water may be introduced towards the lower surface of the case 210 while moving along both side walls of the case 210 into which the laundry detergent is introduced. Accordingly, the wash water will be able to flow towards the detergent inlet 214 after being mixed with the laundry detergent.

[161] In some implementations, as illustrated in FIG. 8A, laundry detergent passages 211, 212 may extend from a rear portion to a front portion on the bottom surface of housing 210 such that each laundry detergent introduced by pumps 231 232 for laundry detergent may leak through them.

[162] The detergent inlet 214 may be formed in the center portion of the bottom surface of the case 210, and the bottom surface of the case 210 inclines at a predetermined angle from the rear portion to the front portion. Thus, each detergent can flow unobstructed towards the detergent inlet 214 .

[163] In some implementations, since the detergent inlet 214 communicates with the tub of the laundry treating device 100, detergent and wash water can be supplied to the tub along the inclined bottom surface of the housing 210.

[164] Since the laundry detergent passages 211, 212 extend towards the detergent inlet 214, and the detergent inlet 214 communicates with the tub of the laundry treating apparatus 100, the laundry detergent moving along the inclined surface of the cabinet 210 may be supplied to the tub after passing through the detergent inlet 214 along with the wash water.

[165] The laundry detergent passage 211, 212 may include a first laundry detergent passage 211 that guides movement of the first laundry detergent, and a second laundry detergent passage 212 placed at a different position by inserting a partition wall 213 therebetween to guide the movement of the second laundry detergent.

By means of the separating wall 213, the first laundry detergent passage 211 and the second laundry detergent passage 212 can be separated from each other, and the first detergent and the second detergent can be prevented from mixing with each other.

[167] The partition wall 213 may have a predetermined height and may extend along the channel between the first laundry detergent channel 211 and the second laundry detergent channel 212 to face the sloping portion 215b from the rear surface of the housing 210.

[168] When detergent and fabric conditioner are mixed with each other, deposits may form. However, in the present disclosure, the laundry detergent flowing through the first laundry detergent passage 211 and the laundry detergent flowing through the second laundry detergent passage 212 do not mix with each other due to the separation wall 213, thereby , preventing the formation of deposits that will build up on the bottom surface of the case.

[169] Each laundry detergent passage 211, 212 can be extended to communicate with the laundry detergent inlet 211a, 211b and the detergent inlet 214 located on the rear surface of the case 210, respectively.

[170] Through the operation of the laundry detergent pump, the first laundry detergent and the second laundry detergent flowing from the rear portion of the body 210 through the laundry detergent passages 211, 212 can move towards the detergent inlet 214. facilities.

[171] In some implementations, sloped portions 215a, 215b having a predetermined slope toward the detergent inlet 214 may be formed on one side of the housing 210.

[172] In some implementations, sloping portions 215a, 215b having a predetermined slope toward the detergent inlet 214 may be placed on both sides of the bottom surface of the housing 210, respectively. The inclined portions 215a, 215b can be formed on both sides with the detergent inlet 214 between them, and each detergent moving through the first laundry detergent passage 211 and the second laundry detergent passage 212 can move freely along towards the inlet 214 for the detergent under its own weight due to the inclined sections 215a, 215b.

[173] In other words, the wash water is not only supplied towards the lower portion of the body 210 into which the laundry detergent is added, but also spills towards the sloping portion 215b to be supplied to the peripheral portion of the detergent inlet 214, thereby moving towards the detergent inlet 214 in a well-mixed state with the laundry detergent.

[174] The detergent storage containers 221, 222 may include detergent storage elements 221c, 222c to store laundry detergent, and storage container lids 221b, 222b to cover each of the storage elements 221c, 222c. detergent.

[175] The detergent storage members 221c, 222c may have a storage space in which an upper portion thereof is open and laundry detergent is stored therein.

[176] The storage container covers 221b, 222b are installed to cover the openings of the detergent storage members 221c, 222c so that the storage spaces in the detergent storage members 221c, 222c are sealed off.

[177] Each of the storage container covers 221b, 222b is provided with a stopper 224 that rotates in one direction to be removable from the storage container covers 221b, 222b, and laundry detergent can be replenished in each of the detergent storage elements 221c, 222c. facilities.

[178] In some implementations, as illustrated in FIG. 8C, a remaining amount detection unit 260 is installed in the rear portion of each of the detergent storage containers 221, 222 to detect whether the remaining amount of laundry detergent stored in the each of the elements 221c, 222c for storing detergent.

[179] When the first detergent storage container 221 and the second detergent storage container 222 are installed in the cabinet 210, the detergent supply device 200 can detect whether or not the remaining amount of detergent stored in each of the detergent storage members is insufficient. , through block 260 detection of the remaining amount. Accordingly, when it is detected that the amount of detergent stored in the detergent storage member is insufficient, the remaining amount detecting unit 260 notifies the information to the user, so that user convenience can be further improved.

[180] For example, when the remaining amount of detergent detected by the detergent detecting unit 260 is less than the predetermined capacity, the user can pull out the detergent supply device 200 from the main body, open the plug 224, and then simply replenish the detergent.

[181] As illustrated in FIG. 8A, the laundry detergent pumps 231, 232 to generate movements of the various laundry detergents are installed in the rear portion of the case 210, and the connection terminal receiving member 270 protrudes toward each of the containers. 221, 222 storage.

[182] In some implementations, as illustrated in FIG. 8B, the connection terminal portion 262 is attached to the rear surface of each of the detergent storage containers 221, 222 along with the support bracket 261 to protrude outward.

[183] A connection terminal portion 262 may be provided above the portion 221a, 222a to receive a pump protruding from the rear portion of the detergent storage container 221, 222. For example, the connection terminal portion 262 and the pump receiving portion 221a, 222a may be placed up and down in the rear portion of the detergent storage container 221, 222.

[184] Accordingly, when the detergent storage containers 221, 222 installed in the storage container frame 210d are attached to the cabinet 210, the remaining amount detecting unit 260 can detect a current inside the detergent storage container 221, 222 to detect the remaining amount. detergent stored in the detergent storage container 221, 222.

[185] I.e. the remaining amount detecting unit 260 is installed on one side of each of the first detergent storage member 221c to accommodate the detergent of the first detergent storage container 221 and the second detergent storage member 222c to accommodate the detergent of the second detergent storage container 222 to detect the remaining amount of detergent stored in each of the detergent storage members 221c, 222c.

[186] For example, as illustrated in FIG. 8C, the remaining amount detection unit 260 may be installed in the rear portion of the first detergent storage container 221 pulled out from the storage container frame 210d.

[187] Specifically, on one side of the rear surface of the first detergent storage member 221c, the connecting portion 221d may be formed to penetrate the rear surface, and the mounting groove 221e may be recessed around the circumference of the connecting portion 221d. The outline of the remaining amount detection unit 260 is positioned to touch the mounting slot 221e.

[188] The mounting groove 221e may be formed around the circumference of the connecting portion 221d. The mounting groove 221e serves to guide the mounting protrusion 261a formed on the contour of the support bracket 261 to be accommodated in the mounting groove 221e.

[189] As illustrated in FIG. 8D, the first detergent storage container 221 and the second detergent storage container 222 can be installed in the storage container frame 210d.

[190] The storage container frame 210d is formed to extend from the front to the back, and is configured to receive the first detergent storage container 221 and the second detergent storage container 222.

[191] The frame 210d for the storage container has a structure in which a predetermined space is formed by surrounding the outer walls on the front, rear, right and left sides, and the space is divided to form the manual detergent dispensing unit 223' and the body receiving portion 223 for air conditioner.

[192] The manual detergent dispenser 223' and the conditioner case receiving portion 223 may be separated by a partition plate 342 installed inside the storage container frame 210d.

[193] The outer wall may include a plurality of planes, and the plurality of planes may extend from the front side to the rear side while having a predetermined angle with each other. Here, the width of the space enclosed by the outer walls, i.e. width in the left-right direction, may be different in the longitudinal direction, i.e. in the forward-backward direction.

[194] The rear end of the storage container frame 210d may be roundly bent and partially support the rear end of the detergent storage container 221, 222 inserted into the storage container frame 210d.

[195] The back wall 210e is placed in the space between the folded portions. The space between the folded portion and the back wall 210e may have a message portion 210f. Here, the folded portion may be connected to the rear wall 210e by the spacer 210g. Those. both outer walls facing the rear wall 210e can be connected by a spacer 210g.

[196] In some implementations, a ledge of limited distance may be formed in the folded portion. The protrusion for limiting the distance protrudes a predetermined distance from the upper side of the bent portion of the outer wall.

[197] The distance limiting protrusion serves to limit the insertion distance by contacting the laundry detergent pump 231, 232 or others when the storage container frame 210d is inserted into the body 210. The back wall 210e forms one side in the longitudinal direction of the frame 210d for storage container, i.e. the outer circumference of the back side, for example. The rear wall 210e supports the rear side of the detergent storage container 221, 222.

[198] The back wall 210e can be extended upward while having a predetermined angle with the bottom surface of the storage container frame 210d.

[199] Through the openings 210f and 210f'' formed by the rear wall 210e, the remaining amount detecting unit 260 provided in the detergent storage container 221, 222 and the pump receiving portion 221a, 222a can protrude to the rear by a predetermined distance.

[200] The pump receiving portion 221a, 222a may protrude towards the laundry detergent pump 231, 232 in the rear portion of the detergent storage container 221, 222. The laundry detergent stored in the detergent storage container 221, 222 can move towards the laundry detergent pump 231, 232 after passing through the pump receiving portion 221a, 222a. Then, the laundry detergent may pass through the first laundry detergent passage 211 and the second laundry detergent passage 212 to be discharged towards the body 210.

[201] The rear wall 210e can be connected by a spacer 210g. The dividing member 210g can divide the hole 210f', 210f'' into a pump receiving hole 210f and a hole 210f'' for the remaining quantity detection unit.

[202] The message portion 210f is a portion in which one side of the container 221, 222 is inserted into the frame 210d for the storage container. For example, the backside in the illustrated implementations may communicate with the outside of the frame 210d for the storage container. The remaining amount detecting unit 260 and the pump receiving portion 221a, 222a provided on the rear side of the detergent storage container 221, 222 can be opened outwards through the communication portion 210f.

[203] I.e. since the message portion 210f is formed in the rear portion of the storage container frame 210d, the remaining amount detection unit 260 provided in the detergent storage container 221, 222 can be electrically connected to an external controller.

[204] The message portion 210f is located on one side in the longitudinal direction of the frame 210d for the storage container. For example, message portion 210f may be located on the back side as illustrated.

[205] The separating member 210g serves to divide the hole 210f', 210f'' into a pump receiving hole 210f on the bottom side and a hole 210f'' for the remaining amount detection unit on the top side.

[206] The separating member 210g can serve to stiffen the structure on the rear side of the storage container frame 210d by connecting the outer wall and the rear wall 210e of the storage container frame 210d.

[207] In some implementations, the separating member 210g may limit the insertion direction and the separation direction of the detergent storage container 221, 222 by dividing the opening into a pump receiving opening 210f' and a remaining amount detecting opening 210f''.

[208] The pump receiving hole 210f is a space through which the pump receiving portion 221a extends. Through the pump receiving hole 210f', a pump valve for the laundry detergent pump 231, 232 can be connected to communicate with the pump receiving portion 221a.

[209] The pump receiving hole 210f' may be positioned below the remaining amount sensor opening 210f'', and the remaining amount sensor opening 210f'' may be positioned above the pump receiving hole 210f'.

[210] Since the hole 332 is divided into a pump receiving hole 210f and a remaining amount sensor hole 210f'' by the separating member 210g, insertion and separating directions of the detergent storage container 221, 222 can be restricted.

[211] I.e. the remaining amount detection sensor 260 is first inserted into the remaining amount detection sensor hole 210f'', and then the check valves 416, 426 are inserted into the pump receiving hole 210f'. In some cases, the check valves 416, 426 are first separated from the pump receiving port 210f', and then the remaining amount detection unit 260 is separated from the remaining amount sensor receiving port 210f''.

[212] FIG. 9A is a sectional view illustrating the state before the first detergent storage container 221 is installed in the cabinet 210, and FIG. 9B is a sectional view illustrating the state after the first detergent storage container 221 means is installed in the housing 210.

[213] FIGS. 9A and 9B illustrate exemplary states in which the remaining amount detection unit 260 is set to detect the remaining amount of detergent in the first detergent storage container 221 . However, as for the second detergent storage container 222, as well as for the first detergent container 221, the remaining amount of detergent can be applied in the same way.

[221] The electrode 263 is made of a metallic material and has a structure adapted to apply an electric current. The electrode 263 may be attached to the support bracket 261 in a manner such as insert molding.

[222] Here, the electrode 263 is in a state where at least a portion thereof is exposed to the outside. Another part of the electrode 263 may be opened inside the first detergent storage member 221c so as to come into contact with the laundry detergent stored in the first detergent storage container 221 .

[223] When one side of the electrode 263 exposed to the first detergent storage member 221c is brought into contact with the stored detergent, a current can be passed through the laundry detergent so that the remaining amount of detergent is detected.

[224] Here, the connection terminal portion 262 can be mounted to the outer portion of the support bracket 261. The connection terminal portion 262 is connected to the connection terminal receiving member 270, so that the remaining amount detecting unit 260 is in a ready state.

[225] The connection terminal receiving member 270 may be attached to the laundry detergent pump 231, 232 and installed facing each of the detergent storage containers 221, 222. When the connection terminal portion 262 is inserted into the connection terminal receiving member 270, they can be electrically connected to each other.

[226] In some implementations, as illustrated in (a) and (b) in FIG. 9B, the connector pin receiving member 262a is installed within the connector terminal portion 262. When the connecting terminal portion 262 is inserted into the connecting terminal receiving member 270, the connecting pin 272a of the connecting terminal receiving member 270 is inserted towards the connecting pin receiving member 262a installed inside the connecting terminal portion 262. Here, the remaining amount detecting unit 260 can detect the remaining amount of detergent and whether the remaining amount of detergent is insufficient by measuring the current value with the laundry detergent stored in each of the detergent storage containers 221, 222 as the medium .

[227] The connection terminal receiving member 270 may include a connection terminal body 271 and a connection terminal 272.

[228] The connection terminal body 271 defines the appearance and can be attached to the body 210.

[229] Here, the connection terminal 272 is fixedly mounted inside the connection terminal body, and when the connection terminal section 262 is inserted, the connection terminal section 262 and the electrode 263 are electrically connected to each other. The connecting pin 272a is fixedly mounted inside the connecting terminal 272, and the connecting pin 272a can protrude towards the connecting pin receiving member 262a so as to be inserted into or pulled out of the connecting pin receiving member 262a.

[230] (a) in FIG. 10A illustrates an example of the support bracket 261 to be attached to the detergent storage container 221, 222, and (b) in FIG. 10A is a perspective view of the support bracket 261. In addition, ( a) Fig. 10B is a perspective view illustrating the remaining amount detecting unit 260, (b) Fig. 10B is a perspective view illustrating examples of the electrode sensor terminal 264 and the electrode sensor 263a, and (c) in Fig. 10B is conceptual view illustrating an exemplary state in which the electrode sensor terminal 264 and the electrode sensor 263a are connected.

[231] The remaining amount detection unit 260 operates in a state in which each of the detergent storage containers 221, 222 is attached to the body 210.

[232] The remaining amount detecting unit 260 can detect the remaining amount of detergent stored in each of the detergent storage containers 221, 222 by applying a predetermined current to the detergent storage element 221c, 222c, then measuring the current detected by the electrode sensor.

[233] The remaining amount detecting unit 260 may be installed in each of the first detergent storage container 221 and the second detergent storage container 222, and can detect the remaining amount of detergent stored in the first detergent storage container 221 and the second detergent container 222 to store detergent.

[234] Here, whether the remaining amount of detergent in the first detergent storage container 221 is insufficient and whether the remaining amount of detergent in the second detergent storage container 222 is insufficient can be determined in the same way by block 260 detection of the remaining quantity.

[235] The remaining amount detecting unit 260 may include a support bracket 261, a connection terminal portion 262, an electrode 263, and a connection terminal receiving member 270.

[236] The support bracket 261 may be attached to the rear surfaces of each of the first and second detergent storage members 221c, 222c by soldering. Here, one surface of the support bracket 261 is placed in the interior of each of the detergent storage members 221c, 222c, and the other surface protrudes outward from each of the detergent storage members 221c, 222c.

[237] The mounting protrusion 261a is formed on the contour of the support bracket 261, and the mounting protrusion 261a can be placed in the mounting groove 221e, which is recessed around the circumference of the connecting portion 221d of each detergent storage member 221c, 222c. Accordingly, the support bracket 261 can be more easily attached to each of the detergent storage members 221c, 222c.

[238] A plurality of electrodes 263 may be mounted inside the support bracket 261.

[239] The support bracket 261 may be attached to the detergent storage container 221, 222 on one side of the rear surface of the detergent storage container 221, 222, and at least a portion of the electrode 263 attached to the support bracket 261 by injection with an insert, may be located inside the first and second elements 221c, 222c for storing detergent.

[240] The electrode 263 may be plural, and at least one electrode sensor may have a different length. Each of the electrode sensors 263a, 263b, 263c may have different heights from the bottom surface of the detergent storage members 221c, 222c. With this structure, the electrode 263 and the laundry detergent in the detergent storage member 221c, 222c can be selectively contacted so that the remaining amount of the laundry detergent is easily detected.

[241] I.e. the electrode 263 is positioned so that at least a portion thereof is opened into the first detergent storage container 221, thereby coming into contact with the laundry detergent stored in the first detergent storage member 221c. When the electrode 263 is brought into contact with the laundry detergent in the first detergent storage element 221c, a current can be passed through the detergent so that the remaining amount of the detergent stored in the first detergent storage container 221 can be detected.

[242] In the same manner as above, the electrode 263 positioned so that at least part of it is open inside the second detergent storage container 222 is brought into contact with the detergent stored in the second detergent storage element 222c, the remaining amount of detergent stored in the second detergent storage container 222 can be detected.

[243] Inside the connection terminal section 262, a sensor-electrode terminal 264 may be installed to support the electrode 263 and transmit electrical signals. Within the terminal 264 of the electrode sensor, an element 262a may protrude to receive the connecting pin.

[244] When the connecting terminal portion 262 is inserted into the connecting terminal receiving member 270, the connecting pin 272a of the connecting terminal receiving member 270 is inserted towards the connecting pin receiving member 262a installed inside the connecting terminal portion 262. Here, the remaining amount detection unit 260 can detect the remaining amount of detergent from the current value with the laundry detergent stored in each of the detergent storage containers 221, 222 as the medium.

[245] As illustrated in FIG. 10B, the electrode 263 may include a horizontal portion 263a'' to be attached to the electrode sensor terminal 264, and a vertical portion 263a' bent from the horizontal portion 263a'' and extending in the direction intersecting with the horizontal section 263a''.

[246] The horizontal portion 263a'' and the vertical portion 263a' may be formed in a direction intersecting with each other.

[247] One end of the horizontal portion 263a'' may be formed with the lugs 263''' protruding outward so that it can be fixed by fitting into the lugs formed on both sides of the electrode sensor terminal 264.

[248] In some implementations, the vertical section 263a' may extend into the interior of the detergent storage containers 221, 222, and one end thereof may open into the interior of the detergent storage containers 221, 222.

[249] Hereinafter, a description will be provided of a method for detecting the remaining amount of laundry detergent stored in the detergent storage containers 221, 222 by the remaining amount detecting unit 260.

[250] As described above, electrode 263 may be plural. The plural electrode 263 may be configured such that at least one electrode has a different length. For example, electrode 263 may have a total of three electrode sensors, i. a first electrode sensor 263a, a second electrode sensor 263b, and a third electrode sensor 263c, as illustrated in FIG. 10B.

[251] Here, the length of the first electrode sensor 263a and the length of the third electrode sensor 263c may be identical. The second electrode sensor 263b may be located between the first electrode sensor 263a and the third electrode sensor 263c and is shorter than the length of the first and third electrode sensors 263a, 263c.

[252] The length of the vertical portion of the first and third electrode sensors 263a, 263c may be longer than the length of the vertical portion of the second electrode sensor 263b.

[253] For example, when a sufficient amount of laundry detergent is stored in the first detergent storage container 221, the first electrode sensor 263a and the third electrode sensor 263c are brought into contact with the laundry detergent. Here, the first electrode sensor 263a and the third electrode sensor 263c are electrically connected through the laundry detergent, and the controller can determine that a predetermined amount of the laundry detergent is stored in the first detergent storage container 221 from the detected current value.

[254] In some cases, when insufficient amount of laundry detergent is stored in the first detergent storage container 221 so that the laundry detergent level is lower than the positions of the first electrode sensor 263a and the third electrode sensor 263c, the first electrode sensor 263a and the third electrode the sensor 263c is not brought into contact with the laundry detergent, and therefore no current can flow through the laundry detergent. Here, since the current value is not detected by the controller, the controller can generate and output a signal indicating that the amount of laundry detergent stored in the first detergent storage container 221 is less than a predetermined level and the laundry detergent needs to be replenished.

[255] Similarly, when a sufficient amount of laundry detergent is stored in the first detergent storage container 221, and the first electrode sensor 263a and the third electrode sensor 263c, as well as the second electrode sensor 263b, are brought into contact with the laundry detergent, the controller can generate a signal indicating that a sufficient amount of laundry detergent is stored in the first detergent storage container 221 according to the detected current value, and outputs the signal to the outside.

[256] In some implementations, according to the state in which the laundry detergent is in contact or not in contact with each of the electrode sensors 263a, 263b, 263c, whether the remaining amount of the laundry detergent stored in each of the containers is 221, 222 for detergent storage, more or less than the reference amount will be automatically detected. In addition, the convenience of the user can be further enhanced by notifying the user of the remaining amount of the stored laundry detergent.

[257] FIG. 11A is a perspective view illustrating an example of one side of the support bracket 261, and FIG. 11B is a conceptual view illustrating an exemplary state in which the laundry detergent travels on one side of the support bracket 261.

[258] As described above, the support bracket 261 can be attached to the rear surfaces of the first and second detergent storage members 221c, 222c, and the electrode 263 mounted on the support bracket 261 can detect the remaining amount of laundry detergent stored in the first and second laundry detergent storage members 221c, 222c.

[259] However, when the laundry detergent is brought into contact with the electrode 263 exposed from the support bracket 261, the remaining amount detection unit may falsely detect that there is sufficient laundry detergent in the detergent storage containers 221, 222. In some implementations, on one surface of the support bracket 261, i. e. on one surface located inside the first and second laundry detergent storage members 221c, 222c, the detergent blocking rib 265 may protrude in a shape surrounding one side of the exposed electrode 263.

[260] As illustrated in FIG. 11A, the detergent blocking rib 265 serves to separate the first electrode sensor 263a, the second electrode sensor 263b, and the third electrode sensor 263c. Accordingly, when the laundry detergent remains on one surface of the support bracket or the residual laundry detergent is stored, the detergent blocking rib 265 prevents the laundry detergent from moving towards each of the electrode sensors 263a, 263b, 263c, thereby preventing the remaining quantity detection unit 260 from malfunctioning.

[261] Here, the detergent blocking rib 265 may include a boundary portion 265c configured to separate the first electrode sensor 263a, the second electrode sensor 263b, and the third electrode sensor 263c.

[262] In some implementations, since the detergent blocking rib 265 is to prevent the electrode sensor from malfunctioning, the detergent blocking rib 265 may include blocking portions 265a, 265b inclined in the vertical direction.

[263] Blocking sections 265a, 265b may have a predetermined slope in the vertical direction. The blocking sections 265a, 265b may be provided in a variety of locations to have different heights. The blocking portions 265a, 265b may include protrusions that protrude from the surface of the support bracket 261.

[264] The blocking portions 265a, 265b serve to guide the movement of the laundry detergent that falls from one surface of the support bracket 261, as illustrated in FIG. 11B, to restrict the movement of the laundry detergent towards the electrode sensors 263a, 263b, 263c .

[265] (a) in Fig. 12 is a perspective view illustrating the rear side of the detergent storage container 221, 222, and (b) in Fig. 12 is a perspective view illustrating the connection terminal portion 262. In addition, (a) in Fig. 13 is a perspective view illustrating an exemplary state in which the laundry detergent pumps 231, 232 are attached to the case 210, and (b) in Fig. 13 is a perspective view illustrating the element 270 to receive the connection terminal.

[266] The connection terminal portion 262 is set to be inserted into the outer portion of the support bracket 261, and is attached to the connection terminal receiving member 270 connected to the laundry detergent pump to serve to enable the operation of the remaining amount detection unit 260.

[267] In some examples, the connection terminal portion 262 may include a support bracket mounting portion 262c that protrudes from the connection terminal portion 262, and the support bracket mounting portion 262c may be inserted into the support bracket 261.

[268] At this time, the connecting pin receiving member 262a can be mounted inside the connecting terminal portion 262, and when the connecting terminal portion 262 is inserted into the connecting terminal receiving member 270, the connecting pin 272a of the connecting terminal receiving member 270 is inserted towards the member. 262a to receive the connecting pin installed inside the section 262 of the connecting terminal. Here, the remaining amount detecting unit 260 can detect the remaining amount of detergent from the current value with the detergent stored in each of the detergent storage containers 221, 222 as the medium.

[269] A plurality of partition wall portions 262b configured to separate the connection pin receiving holes 262d from each other may be formed in the connection terminal portion 262. The sealing element insertion portion 262e may be separated by a plurality of partition wall portions 262b, and a sealing member 280, which will be described later, may be placed therein.

[270] The connection terminal receiving member 270 may include a connection terminal body 271 and a connection terminal 272.

[271] The connection terminal body 271 defines the appearance. On one side of the connection terminal body 271, the connection portion 221d may be formed to supply power to enable the connected state of the connection terminal 272.

[272] The connection terminal 272 is fixedly installed inside the connection terminal body, and when the connection terminal section 262 is inserted, the connection terminal section 262 and the electrode 263 are electrically connected to each other. The connecting pin 272a is fixedly mounted inside the connecting terminal 272, and the connecting pin 272a can protrude towards the connecting pin receiving member 262a so as to be inserted into or pulled out of the connecting pin receiving member 262a.

[273] The connection terminal receiving member 270 is connected to the laundry detergent pumps 231, 232 and can be installed facing each of the detergent storage containers 221, 222. The connection terminal portion 262 may be inserted into the connection terminal receiving member 270 to be electrically connected thereto.

[274] In some implementations, as illustrated in (b) in FIG. 13, the detergent outlet 271a may be formed in the lower surface of the connection terminal body 271 so that the laundry detergent flowing into the connection terminal body 271 is discharged. through him.

[275] The detergent outlet 271a is formed in a predetermined shape to pass through up and down, and has a structure that can smoothly discharge the laundry detergent flowing into the connection terminal body 271. The detergent outlet 271a may be formed in plural, and they may be parallel to each other at a predetermined distance.

[276] (a), (b), and (c) in FIG. 14 are conceptual views, each illustrating a sealing member 280.

[277] The detergent supply device 200 may be configured to further include a sealing member 280 inserted into the connection terminal body 271.

[278] The connection terminal body 271 defines the appearance and may be attached to the body 210. The connection terminal receiving member 270 may include a connection terminal body 271 and a connection terminal 272.

[279] The sealing member 280 may be formed of a rubber material to seal between each terminal supporting the electrode 263.

[280] In some implementations, the sealing element 280 may divide the connection terminals 272 into different areas to block them from each other. For example, as illustrated in (a) and (b) in Fig.14, the sealing element 280 can be divided into three areas.

[281] The connecting protrusions 281 may protrude in one direction on one surface of the sealing member 280 so as to be attached to the connection terminal body 271. The connecting protrusions 281 can be inserted into the connection terminal body 271, and the sealing member 280 can be attached to the connection terminal body 271.

[282] In some implementations, on the other surface of the sealing member 280, a protective portion 282 protruding in one direction so as to be attached to the connection terminal portion 262 may be provided.

[283] The sealing member 280 is located between the connection terminal portion 262 and the connection terminal body 271.

[284] The connection terminal 272 is fixedly mounted inside the connection terminal body 271, and when the connection terminal section 262 is inserted, the connection terminal section 262 and the electrode 263 are electrically connected to each other. Here, the sealing member 280 may be placed to be inserted into a plurality of dividing walls 262b configured to separate the connecting pin receiving holes 262d from each other.

[285] FIG. 15 is a horizontal sectional view of the detergent supply device 200 illustrating the movement of the laundry detergent stored in the detergent storage container.

[286] As described above, when the body 210 is inserted into the interior of the main body 110, the laundry detergent stored in each of the detergent storage containers 221, 222 can be introduced into the body 210 by operating the detergent pump 230 to laundry installed at the back of each container 221, 222 for storing detergent.

[287] Here, at the back surface portion of each detergent storage container 221, 222, the pump receiving portion 221a, 222a may protrude from the laundry detergent pump 231, 232 to communicate with the interior of the detergent storage container 221, 222. facilities.

[288] In some implementations, the first laundry detergent suction tube 231a protruding from the first laundry detergent pump 231 may be positioned in a state of placement in the first portion 221a to receive the pump of the first storage container 221, and thus , the laundry detergent stored in the first detergent storage container 221 can be sucked in by operation of the first laundry detergent pump 231 and discharged through the first laundry detergent inlet 211a through the first detergent inlet tube 241 for washing washing.

[289] In addition, the second pump valve 232a protruding from the second laundry detergent pump 232 may be disposed in the second pump receiving portion 222a of the second detergent storage container 222, and thus the detergent laundry stored in the second detergent storage container 222 can be sucked in by operation of the second laundry detergent pump 232 and discharged through the second laundry detergent inlet 211b through the second laundry detergent inlet tube 242.

[290] At this time, the wash water may be brought in through the wash water inlet portions 251c, 251c', 251c'' provided in the wash water dispenser 251, and the brought in wash water may move through the first and second channels 251a, 251b for washing water and then discharged towards the slope portion 215b through the opening 254 for moving water for washing.

[291] The wash water may be mixed with the laundry detergent moving towards the detergent inlet 214 through the first laundry detergent passage 211 and the second laundry detergent passage 212, and may move downward under its own weight and then move towards the tank.

[292] In other words, the laundry detergent moving into the body 210 from each detergent storage container 221, 222 through the detergent inlet 214 can move through the first and second channels 211, 212 and then be mixed with the wash water. flowing into the housing 210, and then fed into the tub through the detergent inlet 214.

[293] In some implementations, the remaining amount detection unit 260 installed in the detergent supply device 200 detects the remaining amount of laundry detergent stored in each detergent storage container 221, 222, and when the remaining amount of laundry detergent is lower than control value, the remaining amount detecting unit 260 notifies users of this information, thereby improving user convenience.

[294] Hereinafter, a method of manufacturing detergent storage containers 221, 222 will be described.

[295] FIG. 16 is a flowchart illustrating a method for manufacturing a detergent storage container 221, 222.

[296] The first detergent storage container 221 and the second detergent storage container 222 are installed in the cabinet 210, respectively, to supply various laundry detergents stored in each of the detergent storage members 221c, 222c through each of the pumps. 231, 232 for laundry detergent.

[297] Here, the remaining amount detection unit 260 installed in each of the detergent storage containers 221, 222 can detect the remaining amount of laundry detergent stored in each detergent storage element 221c, 222c by detecting the current applied in each container 221, 222 for storing detergent. Accordingly, the remaining amount of detergent stored in each detergent storage container 221, 222 is automatically detected by the remaining amount detecting unit 260, thereby further improving user convenience.

[298] The method for manufacturing the detergent storage containers 221, 222 may include fabricating the detergent storage element 221c, 222c (S10), fabricating the remaining amount detecting unit 260 (S20), attaching the remaining amount detecting unit 260 to the element 221c , 222c to store detergent (S30), attaching the storage container cover 221b, 222b to the detergent storage member 221c, 222c (S40), and attaching the connection terminal portion 262 to the remaining amount detecting unit 260 (S50).

[299] The detergent storage member 221c, 222c may be made of a plastic material and may be produced by an injection molding process after the mold is made.

[300] The detergent storage member 221c, 222c can be produced by the first step by introducing plastic after the "U" mold is made.

[301] For example, the first step may include the step of manufacturing the detergent storage element 221c, 222c.

[302] Here, the first step S10 may further include the step of forming a connecting portion 221d penetrating the rear surface of the detergent storage member 221c, 222c. However, the connecting portion 221d may be formed during the injection process of the detergent storage member 221c, 222c, in which case a separate manufacturing process is not needed.

[303] In some implementations, the first step S10 may further include forming a mounting groove 221e, configured to guide the remaining amount detection unit 260 to be installed on the circumference of the connecting portion 221d.

[304] The mounting groove 221e may be formed around the circumference of the connecting portion 221d penetrating the rear surface of each detergent storage member 221c, 222c. As such, the process of forming the mounting groove 221e may further include a separate manufacturing step, or may not further include a separate step through the injection process of the detergent storage member 221c, 222c.

[305] In some implementations, as illustrated in FIG. 10, the method of manufacturing the detergent storage container 221, 222 may include a second step S20 of manufacturing the remaining amount detection unit 260.

[306] The second step may include the step of manufacturing the remaining quantity detection unit 260.

[307] The remaining amount detecting unit 260 can be produced by the insert molding method, so that the plurality of electrodes 263 are attached to the support bracket 261 having one plate-shaped surface.

[308] Here, the electrode 263 includes a horizontal portion 263a'' to be attached to the electrode sensor terminal 264, and a vertical portion 263a' bent from the horizontal portion 263a'' and extending in a direction intersecting with the horizontal portion 263a' ', and its shape is the same as the shape described above in Fig.10.

[309] When the plurality of electrodes 263 are installed by the insert molding method, at least a part of the electrode 263 is opened on one side of the support bracket 261, and the other side protrudes outward, so that the connection terminal portion 262 is connected thereto.

[310] In some implementations, the second step may include forming the mounting lug 261a to fit the mounting slot 221e around the outer circumference of the support bracket 261.

[311] Here, the step of forming the mounting protrusion 261a may refer to the step of marking the marking portion in the mounting groove 221e, so that the remaining amount detecting unit 260 can be easily seated on the connecting portion 221d formed on the back surface of the detergent storage member 221c, 222c .

[312] The mounting protrusion 261a may be formed by a separate manufacturing process of the support bracket 261, or may be formed integrally by an insert molding process in which a plurality of electrodes 263 are attached to the support bracket 261.

[313] In some implementations, the second step S20 may include the step of forming a detergent blocking rib 265 on one surface located within the detergent storage member 221c, 222c of the support arm 261 to protrude in a shape surrounding one side of the exposed electrode 263 .

[314] Here, the detergent blocking rib 265 may be integrally formed with the support bracket 261, or may be manufactured as a separate piece and then attached to the support bracket 261 by soldering.

[315] The manufacturing method of the detergent storage container 221, 222 may include a third step S30 in which the remaining amount detecting unit 260 is tightly glued to the connecting portion 221d.

[316] The third step S30 may include the step of bringing the remaining amount detecting unit 260 into close contact with the connecting portion.

[317] The third step S30 may be performed as a step of placing the mounting protrusion 261a in the mounting groove 221e, and then attaching the mounting protrusion 261a to the mounting groove 221e by soldering or heat welding.

[318] Since the mounting groove 221e and the mounting protrusion 261a are positioned in contact with each other, the support bracket 261 can be more easily fitted onto the detergent storage member 221c, 222c. Accordingly, assembly productivity can be further improved.

[319] The method of manufacturing the detergent storage container 221, 222 may include a fourth step S40 of attaching the storage container lid to the upper portion of the detergent storage member 221c, 222c.

[320] The fourth member S40 may refer to the step of attaching the storage container lid 221b, 222b to the detergent storage member 221c, 222c along the upper surface of the detergent storage member 221c, 222c by heat sealing.

[321] The circumferential surface of the storage container lid 221b, 222b and the upper opening surface of the detergent storage member 221c, 222c can be supported by each other, and they can be attached to each other by forming a weldable surface 221f by a heat sealing method.

[322] The manufacturing method of the detergent storage container 221, 222 may include a fifth step S50 of attaching the connection terminal portion 262 for electrical connection to the open outer surface of the remaining amount detecting unit 260.
