[0133] The dishwasher 1 may be configured to put one of the detergent stored in the detergent box 90 or the solid detergent loaded in the automatic detergent feeding device 1000 , selected by the user, into the tub 12 .

[0134] The automatic detergent feeding device 1000 may be disposed on the inner surface 21 of the door 20. The automatic detergent feeding device 1000 may be provided to be combined with the inner surface 21 of the door 20.

[0135] The detergent box 90 may be disposed on the inner surface 21 of the door 20. The automatic detergent injection device 1000 and the detergent box 90 may be disposed to be aligned along the third direction Z as the up-down direction when the door 20 closes the tub 12.

[0136] Since the automatic detergent feeding device 1000 is disposed at the door 20 , it can be configured to rotate together with the door 20 when the door 20 rotates.

[0137] When the position where the door 20 closes the tub 12 is defined as the first position 20A of the door 20 , and the position where the door 20 opens the tub 12 is defined as the second position 20B of the door 20 , the door 20 may be configured to move between the first position 20A and the second position 20B to open and close the tub 12 .

[0138] The second position 20B of the door 20 may be defined as any one of the positions where the door 20 opens the tub 12, preferably, a position where the tableware stored in the tub 12 can be led out of the tub 12. As an example, the second position 20B of the door 20 may be a position where the extension direction of the inner surface 21 of the door 20 corresponds to the first direction X.

[0139] Automatic detergent dispenser 1000 may be configured to move in conjunction with door 20 between a first position 1000A of automatic detergent dispenser 1000 corresponding to first position 20A of door 20 and a second position 1000B of automatic detergent dispenser 1000 corresponding to second position 20B of door 20 .

[0140] When door 20 closes tub 12 , automatic detergent injector 1000 may be disposed at first position 1000A, and when door 20 opens tub 12 , automatic detergent injector 1000 may be disposed at second position 1000B.

[0141] like Figure 3 As shown, the user can load a plurality of solid detergents into automatic detergent feeder 1000 when automatic detergent feeder 1000 is arranged at second position 1000B.

[0142] The user may open the storage chamber cover 1140 of the automatic detergent injection device 1000 and load a plurality of solid detergents into the storage chamber 1200 .

[0143] In the prior art, whenever the dishwasher washes dishes, the user has to load detergent into the automatic detergent feeder or the detergent box each time, which causes inconvenience to the user. On the contrary, the automatic detergent feeder 1000 of the dishwasher 1 according to an embodiment can be configured to allow the user to load multiple solid detergents into the automatic detergent feeder 1000 during one loading, and when the dishwasher 1 performs a washing stroke, only one of the multiple solid detergents can be fed into the interior of the barrel 12 during one washing stroke.

[0144] During the washing cycle of dishwasher 1, since a plurality of solid detergents are retained inside automatic detergent feeder 1000, water may flow into automatic detergent feeder 1000 during the washing cycle, thereby possibly damaging the plurality of solid detergents.

[0145] Since automatic detergent feeding device 1000 moves between first position 1000A and second position 1000B, a problem may arise in that a plurality of solid detergents loaded in automatic detergent feeding device 1000 are separated from the positions where they are stored.

[0146] Hereinafter, automatic detergent dispenser 1000 which can solve the above-mentioned problems will be described in detail.

[0147] Figure 4 is an exploded perspective view of an automatic detergent feeding device for a dishwasher according to an embodiment. Figure 5 is an exploded perspective view of an automatic detergent feeding device of a dishwasher according to an embodiment of the present invention in another direction. Figure 6 This is a perspective view of a state where a part of the automatic detergent feeding device of a dishwasher is removed according to an embodiment. Figure 7 is an enlarged perspective view of a part of an automatic detergent feeding device of a dishwasher according to an embodiment. Figure 8 FIG. 1 is a diagram showing a state where a part of the automatic detergent feeding device of a dishwasher according to an embodiment of the present invention is removed.

[0148] like Figure 4 and Figure 5 As shown, the automatic detergent feeding device 1000 may include a housing 1100 .

[0149] The housing 1100 may include a first housing 1110 forming a storage chamber 1200 described later and a second housing 1120 coupled to the first housing 1110 .

[0150] The first housing 1110 may be provided to be combined with the inner surface 21 of the door 20 .

[0151] The second housing 1120 may be configured to be combined with the first housing 1110 in the first direction X when the automatic detergent dispenser 1000 is arranged at the first position 1000A.

[0152] The second housing 1120 may form a storage chamber 1200 together with the first housing 1110. The second housing 1120 may include a storage chamber opening 1121 configured to open the storage chamber 1200 to the outside. The second housing 1120 may include an inlet 1122 configured to communicate with the placement portion 1400 described later and to discharge solid detergent from the automatic detergent inlet device 1000 and be inlet into the tub 12.

[0153] The housing 1100 may include a middle housing 1130 disposed between the first housing 1110 and the second housing 1120 and supporting the ejector 1300 and the like disposed inside the housing 1100 .

[0154] As an example, the ejector 1300 and other components may be disposed in the first housing 1110 and supported by the intermediate housing 1130. As an example, the ejector 1300 and other components may be disposed in the second housing 1120 and supported by the intermediate housing 1130.

[0155] As an example, the intermediate housing 1130 may be formed as one body with the first housing 1110. As an example, the intermediate housing 1130 may be formed as one body with the second housing 1120.

[0156] The housing 1100 may include a storage chamber cover 1140 disposed on the second housing 1120 and configured to open and close the storage chamber opening 1121 .

[0157] The housing 1100 may include an inlet cover 1150 disposed on the second housing 1120 and configured to open and close the inlet 1122 .

[0158] The first housing 1110 may include a control device placement portion 1111 disposed in a direction opposite to a direction in which the first housing 1110 is combined with the second housing 1120 and is provided with a control device 1900 for controlling the automatic detergent feeding device 1000 .

[0159] As an example, the control device placement portion 1111 may be arranged inside the housing 1100 formed by combining the second housing 1120 with the first housing 1110. As an example, the control device placement portion 1111 may be arranged inside the housing 1100 formed by combining the second housing 1120 with the first housing 1110.

[0160] The first housing 1110 may include a control device cover 1112 that covers the control device placement portion 1111 from the outside. Since the control device cover 1112 is arranged outside the internal space of the housing 1100 instead of being arranged in the internal space of the housing 1100 formed by combining the first housing 1110 and the second housing 1120, when the control device 1900 needs to be replaced, the control device 1900 can be easily replaced without disassembling the first housing 1110 and the second housing 1120.

[0161] The control device 1900 may control driving of the ejector 1300 and the placement section 1410 described later, and may control the automatic detergent feeding device 1000 based on sensing values ​​of various sensors.

[0162] The control device 1900 may be configured to be able to communicate with a main control device of the dishwasher 1. As an example, the control device 1900 and the main control device may constitute a control unit of the dishwasher 1.

[0163] The main control device may obtain user input through an input unit of the dishwasher 1 or a mobile device, and may control the driving of the dishwasher 1 based on the user input.

[0164] The main control device may transmit the received information on the user input to the control device 1900. The control device 1900 may control the automatic detergent dosing device 1000 based on the information on the input received from the main control device.

[0165] The automatic detergent feeding device 1000 may include a wire W that electrically connects the control device 1900 with electrical components configured to drive the automatic detergent feeding device 1000. The wire W may electrically connect electrical components (a drive motor 1320, a placement section drive unit 1470, and various sensors) configured to drive the automatic detergent feeding device 1000 to feed one of a plurality of solid detergents loaded inside the storage chamber 1200, 1200' into the tub 12 with the control device 1900.

[0166] As an example, the wire W can electrically connect the main control device, the power supply unit and the control device 1900 of the dishwasher 1. As an example, the wire W can be set to electrically connect only the various electrical components of the automatic detergent feeding device 1000 and a part of the control device 1900 or the main control device of the dishwasher 1.

[0167] As an example, at least a portion of the various electrical components and sensors of the automatic detergent dispenser 1000, the control device 1900 or the main control device of the dishwasher 1, etc. can be configured to send and receive signals to each other via wireless communication rather than being electrically connected to each other via wires W.

[0168] Control device 1900 may control automatic detergent feeder 1000 based on values ​​sensed by various sensors of automatic detergent feeder 1000. This will be described in detail later.

[0169] like Figures 6 to 8 As shown, the automatic detergent feeding device 1000 may include a storage chamber 1200 configured to load a plurality of solid detergents.

[0170] The storage chamber 1200 may be configured such that when the automatic detergent feeding device 1000 is arranged at the first position 1000A, a plurality of solid detergents are stacked in a third direction Z, which is an up-down direction. As an example, the storage chamber 1200 may be configured as a plurality of storage chambers 1200, 1200'. However, for ease of description, the description will be based on one storage chamber 1200.

[0171] The storage chamber 1200 may be formed by a space formed by the first housing 1110 and the second housing 1120. The storage chamber 1200 may be formed by a space having a long side 1201 extending in the third direction Z when the automatic detergent feeding device 1000 is arranged in the first position 1000A, so that a plurality of solid detergents are stacked and loaded in the third direction Z.

[0172] As an example, the storage chamber 1200 may be formed by a space formed by the first housing 1110. As an example, the storage chamber 1200 may be formed by a space formed by the second housing 1120.

[0173] When the storage chamber cover 1140 opens the storage chamber opening 1121, the storage chamber 1200 can be opened to the outside through the storage chamber opening 1121. Figure 3 As shown, when the automatic detergent injection device 1000 is arranged at the second position 1000B, the user can open the storage chamber cover 1140 and inject a plurality of solid detergents into the storage chamber 1200 to load the plurality of solid detergents into the storage chamber 1200 .

[0174] Since the automatic detergent injection device 1000 is disposed on the inner surface 21 of the door 20, when the door 20 is opened, the automatic detergent injection device 1000 is disposed outside the washing chamber C, so that the user can easily inject detergent.

[0175] In order to store a plurality of solid detergents, the storage chamber 1200 may be configured to have a volume greater than a predetermined size. As described above, since the automatic detergent injection device 1000 is arranged on the inner surface 21 of the door 20, when the volume of the storage chamber 1200 increases in the first direction X, the volume of the washing chamber C may decrease. The storage chamber 1200 may be configured to stack a plurality of solid detergents in a third direction Z as an up-and-down direction when the automatic detergent injection device 1000 is located in the first position 1000A, so as to prevent the volume of the storage chamber 1200 from increasing in the first direction X.

[0176] When the automatic detergent feeding device 1000 is arranged at the first position 1000A, a plurality of solid detergents may be loaded in the storage chamber 1200 in a stacked arrangement only in the third direction Z, and not arranged in the first direction X.

[0177] Since the storage chamber 1200 is formed so that a plurality of solid detergents are stacked only in the third direction Z, the space of the washing chamber C can be maximized in the first direction X as described above, and in the automatic detergent feeding device 1000, the space of the storage chamber 1200 in the second direction Y can also be ensured.

[0178] Since the storage chamber 1200 is formed so that a plurality of solid detergents are stacked only in the third direction Z, the driving structure of the ejector 1300 such as the transmission part 1330 of the automatic detergent dispensing device 1000 or the electrical structure of the control device 1900 can be arranged in the second direction Y relative to the storage chamber 1200, so that the volume of the automatic detergent dispensing device 1000 in the second direction Y can be minimized.

[0179] Accordingly, on the inner surface 21 of the door 20, an additional structure other than the automatic detergent dispensing device 1000 can be arranged on the outside of the automatic detergent dispensing device 1000 in the second direction Y, so as to increase the size ratio of the volume of the internal space of the barrel 12 relative to the volume of the main body 10 of the dishwasher 1.

[0180] Not limited thereto, a plurality of solid detergents may be loaded in the storage chamber 1200 in a stacked arrangement only in the second direction Y as the left-right direction when the automatic detergent feeding device 1000 is arranged at the first position 1000A.

[0181] The automatic detergent feeding device 1000 may include an ejector 1300 that moves one of the plurality of solid detergents to the outside of the storage chamber 1200 to discharge one of the plurality of solid detergents loaded in the storage chamber 1200 from the storage chamber 1200. As an example, the ejector 1300 may be provided as a plurality of ejectors 1300, 1300' in a number corresponding to the plurality of storage chambers 1200, 1200'. However, for ease of description, description will be made based on one ejector 1300.

[0182] The ejector 1300 may be configured to discharge a lowermost solid detergent arranged in the third direction Z among a plurality of solid detergents stacked along the third direction Z from the storage chamber 1200 when the automatic detergent injection device 1000 is arranged in the first position 1000A.

[0183] The ejector 1300 may be arranged at one side 1201a of the long side 1201 in the extending direction of the long side 1201. When the automatic detergent dispenser 1000 is arranged at the first position 1000A, the one side 1201a of the long side 1201 may be arranged at the lower side in the third direction Z, and the other side 1201b of the long side 1201a may be arranged at the upper side.

[0184] The ejector 1300 may be disposed at a lower portion of the storage chamber 1200 in the third direction Z to discharge a lowermost solid detergent disposed in the third direction Z among a plurality of solid detergents stacked in the third direction Z from the storage chamber 1200 .

[0185] When automatic detergent feeding device 1000 is arranged at first position 1000A, ejector 1300 may discharge solid detergents located closest to lower surface 1220 of storage chamber 1200 among the plurality of solid detergents to the outside of storage chamber 1200 .

[0186] As an example, the ejector 1300 may be configured to pressurize a solid detergent disposed on the lower surface 1220 of the storage chamber 1200 among the plurality of solid detergents. The solid detergent being disposed on the lower surface 1220 means that the solid detergent is supported by the lower surface 1220, or the solid detergent is arranged to be in contact with the lower surface 1220, thereby meaning that the solid detergent is arranged at a position where it can be pressurized by the ejector 1300 and discharged from the storage chamber 1200.

[0187] The storage chamber 1200 may include a storage chamber discharge port 1210 provided to allow one solid detergent to be discharged to the outside of the storage chamber 1200 by the ejector 1300 .

[0188] The storage chamber discharge port 1210 may be disposed at a lower portion of the storage chamber 1200 to discharge a lowermost solid detergent disposed in the third direction Z among a plurality of solid detergents stacked in the third direction Z to the outside of the storage chamber 1200 .

[0189] The storage chamber discharge port 1210 and the ejector 1300 are both disposed at a lower portion of the storage chamber 1200 so that a lowermost solid detergent among a plurality of solid detergents stacked in the third direction Z may be discharged to the outside of the storage chamber 1200 .

[0190] The storage chamber 1200 may be configured to stack a plurality of solid detergents in a third direction Z, so that when the bottommost solid detergent among the plurality of solid detergents is discharged to the outside of the storage chamber 1200, the plurality of solid detergents may move downward based on the stacking direction by gravity.

[0191] Since all the solid detergents move downward, the solid detergents arranged immediately above the solid detergents discharged to the outside of the storage chamber 1200 can be moved to a position adjacent to the lower surface 1220 of the storage chamber 1200, so as to be arranged in the space where the discharged solid detergents were originally located. The solid detergents can be arranged to be discharged to the outside of the storage chamber 1200 by the ejector 1300 in the next washing stroke of the dishwasher 1.

[0192] That is, when the automatic detergent injection device 1000 is arranged in the first position 1000A, the storage chamber 1200 is configured to stack a plurality of solid detergents in a third direction Z, and the ejector 1300 is arranged at the lower portion of the storage chamber 1200, so that the plurality of solid detergents can be discharged to the outside of the storage chamber 1200 in the order of stacking starting from the bottom in the third direction Z.

[0193] Without being limited thereto, the ejector 1300 may be configured to discharge an uppermost solid detergent arranged in the third direction Z among a plurality of solid detergents stacked in the third direction Z from the storage chamber 1200 .

[0194] like Figure 7 As shown, when the solid detergent D is shaped such that the lateral length d1 and the longitudinal length d2 are greater than the height h, the solid detergent D may be loaded in the storage chamber 1200 in a manner of being stacked in the storage chamber 1200 in the direction of the height h.

[0195] In the solid detergent D described below, it is assumed that the lateral length d1 is formed to be larger than the longitudinal length d2 and the height h.

[0196] As an example, the solid detergent D may be loaded in the storage chamber 1200 in such a manner that a direction formed by a minimum length among a lateral length d1 , a longitudinal length d2 , and a height h of the solid detergent D corresponds to a stacking direction of a plurality of solid detergents.

[0197] This is to maximize the amount of solid detergent D that can be loaded into the storage chamber 1200 .

[0198] As an example, when the automatic detergent dispensing device 1000 is arranged in the first position 1000A, the solid detergent D can be loaded into the storage chamber 1200 along a direction so that the surface of the solid detergent D formed by the horizontal length d1 and the longitudinal length d2 directions is opposite to the area S of the storage chamber 1200 formed by the first direction X and the second direction Y.

[0199] As an example, a plurality of solid detergents D may be stacked along a height h direction of the solid detergents D inside the storage chamber 1200 .

[0200] The solid detergent may be set to have various sizes according to the composition, function or manufacturer of the solid detergent, but the volume of the solid detergent may be determined mainly in proportion to the volume size of the washing chamber of the dishwasher. Since the volume of the washing chamber is set to a size within a predetermined range, the volume of the solid detergent may also be set to a size within a predetermined range, whereby the lateral length, longitudinal length and height of the solid detergent may be designed to be similar regardless of its type.

[0201] The solid detergent D described below may be defined as a suitable solid detergent D that can be loaded into the automatic detergent feeding device 1000 of the dishwasher 1 according to an example, and the lateral length d1, longitudinal length d2, and height h of the solid detergent D are defined as approximate values ​​of the lateral lengths, longitudinal lengths, and heights of various solid detergents that can be roughly loaded into the automatic detergent feeding device 1000 of the dishwasher 1, and are defined as values ​​that can vary within a predetermined range. As an example, the lateral length d1 and the longitudinal length d2 are lengths defined by the dimensions formed along the first direction X and the second direction Y, and the lateral length may also be defined as d2, and the longitudinal length may also be defined as d1.

[0202] When the automatic detergent feeding device 1000 is arranged in the first position A, the area s of the storage chamber 1200 in the first direction X and the second direction Y (hereinafter referred to as the cross-sectional area of ​​the storage chamber 1200) can be set to a size that can easily load the solid detergent D and enable it to be stacked in the third direction Z.

[0203] The cross-sectional area S of the storage chamber 1200 may be formed by a pair of sides having a transverse length L1 extending along the second direction Y and a pair of sides having a longitudinal length L2 extending along the first direction X when the automatic detergent feeding device 1000 is arranged in the first position 1000A. As an example, the transverse length L1 and the longitudinal length L2 are lengths defined based on the size formed along the first direction X and the second direction Y, and the transverse length may also be defined as L2, and the longitudinal length may also be defined as L1.

[0204] The lateral length L1 of the cross-sectional area S of the storage chamber 1200 is the length in the second direction Y between the right side surface 1230 and the left side surface 1240 of the storage chamber 1200, and the longitudinal length L2 of the cross-sectional area S of the storage chamber 1200 is the length in the first direction X between the inner surface 1260 of the storage chamber 1200 and the storage chamber opening 1121.

[0205] When the solid detergent D is loaded into the storage chamber 1200, one side of the solid detergent D having a lateral length d1 can be arranged to correspond to an edge of the storage chamber 1200 having a lateral length L1 having a cross-sectional area S, and the other side of the solid detergent D having a longitudinal length d2 can be arranged to correspond to an edge of the storage chamber 1200 having a longitudinal length L2 having a cross-sectional area S.

[0206] As described above, since the longitudinal length d2 of the solid detergent D is formed to be smaller than the transverse length d1, the transverse length L1 of the cross-sectional area S can be formed to be larger than the longitudinal length L2. In addition, since the transverse length d1 of the solid detergent is formed to be larger than the height h of the solid detergent D, the longitudinal length L2 of the cross-sectional area S can also be formed to be larger than the height h of the solid detergent D.

[0207] The lateral length L1 of the cross-sectional area S may be set to be longer than the lateral length d1 of the solid detergent D by approximately 10% to 30% of the lateral length d1 of the solid detergent D.

[0208] The longitudinal length L2 of the cross-sectional area S may be set to be longer than the longitudinal length d2 of the solid detergent D by approximately 10% to 30% of the longitudinal length d2 of the solid detergent D.

[0209] The cross-sectional area S of the storage chamber 1200 may be formed with the above-mentioned value so that when the bottommost solid detergent arranged in the third direction moves to the outside of the storage chamber 1200 by the ejector 1300, the plurality of solid detergents can be stably moved downward in the storage chamber 1200 while maintaining a stacked arrangement.

[0210] When the lateral length L1 and the longitudinal length L2 of the cross-sectional area S are formed to be longer than the lateral length d1 and the longitudinal length d2 of the solid detergent D, which is approximately equivalent to a length less than 10% of the lateral length d1 and the longitudinal length d2 of the solid detergent D, a plurality of solid detergents move downward inside the storage chamber 1200 and become stuck inside the storage chamber 1200, thereby preventing the solid detergents from moving downward stably.

[0211] As an example, when the bottom solid detergent arranged in the third direction Z among the stacked multiple solid detergents moves downward, it may be stuck on the inside of the storage chamber 1200 and cannot be placed on the lower surface 1220 of the storage chamber 1200. Therefore, even if the ejector 1300 is driven, the pressurizing portion 1312a described later cannot easily pressurize the bottom solid detergent arranged in the third direction Z, so that the solid detergent may not be discharged to the outside of the storage chamber 1200.

[0212] When the lateral length L1 and the longitudinal length L2 of the cross-sectional area S are formed to be longer than the lateral length d1 and the longitudinal length d2 of the solid detergent D by a length approximately equivalent to 30% longer than the lateral length d1 and the longitudinal length d2 of the solid detergent D, the stacked arrangement of the solid detergents may collapse due to rotational movement, etc. while moving downward inside the storage chamber 1200.

[0213] As an example, since the cross-sectional area S is formed wider than the solid detergent, the solid detergent may rotate or move in an inclined direction relative to the third direction Z when moving downward, causing multiple solid detergents to move simultaneously in the first direction X or the second direction Y without moving in the third direction, and thus may not be able to maintain a stacked arrangement.

[0214] Therefore, the lateral length L1 and the longitudinal length L2 of the cross-sectional area S can be set to be longer than the lateral length d1 and the longitudinal length d2 of the solid detergent D, which is approximately 10% to 30% of the lateral length d1 and the longitudinal length d2 of the solid detergent D.

[0215] Since the longitudinal length L2 of the cross-sectional area S of the storage chamber 1200 is formed to be longer than the longitudinal length d2 of the solid detergent D, the automatic detergent feeding device 1000 may have a predetermined thickness in the direction in which the longitudinal length L2 extends.

[0216] Accordingly, when the door 20 is disposed at the first position 20A, the automatic detergent dispenser 1000 protrudes from the door 20 toward the inside of the tub 12 along the first direction X, so that the space inside the tub 12 may be partially narrowed.

[0217] In particular, for the lower basket 51 arranged at a height substantially corresponding to the automatic detergent feeder 1000 in the third direction Z, when the door 20 is arranged in the first position 20A, it may collide with the automatic detergent feeder 1000 in the first direction X. In order to prevent this, the automatic detergent feeder 1000 may be arranged to be spaced apart from the lower basket 51 in the first direction X when arranged in the first position 1000A. As an example, the automatic detergent feeder 1000 may be arranged to be spaced apart from the middle basket 52 in the first direction X when arranged in the first position 1000A.

[0218] In addition, the door 20 is arranged in the second position 20B, so that the lower basket 51 can be led out to the front of the barrel 12 along the first direction X. When the lower basket 51 is led out to the front, since the automatic detergent feeding device 1000 is configured to have a predetermined thickness in the extension direction of the longitudinal length L2, the leading out of the lower basket 51 may be limited by the thickness of the automatic detergent feeding device 100.

[0219] The automatic detergent dispenser 1000 may be provided to be coupled to the inner surface 21 of the door 20. When the automatic detergent dispenser 1000 is coupled to the inner surface 21, at least a portion of the automatic detergent dispenser 1000 may be coupled to the door 20 in a manner that the automatic detergent dispenser 1000 is inserted into the inner side of the door 20 in the first direction X.

[0220] Thus, when the automatic detergent injector 1000 is arranged at the first position 1000A, a predetermined spacing distance between the automatic detergent injector 1000 and the lower basket 51 in the first direction X may be easily generated.

[0221] Thus, when the automatic detergent feeder 1000 is arranged in the second position 1000B, the protrusion of the automatic detergent feeder 1000 in the third direction Z can be minimized, so that when the lower basket 51 is led out along the first direction X, it can be easily led out without being restricted by the automatic detergent feeder 1000.

[0222] As an example, the automatic detergent feeding device 1000 may be combined with the inner surface 21 of the door 20 so that when the automatic detergent feeding device 1000 is arranged in the second position 1000B, the upper end of the automatic detergent feeding device 1000 in the third direction Z is located at a position lower than the lower end of the lower basket 51 in the third direction Z. Thus, when the automatic detergent feeding device 1000 is arranged in the second position 1000B, when the lower basket 51 slides to the outside of the tub 12 and is led out, the lower basket 51 can be led out of the tub 12 without being caught by the automatic detergent feeding device 1000.

[0223] The ejector 1300 may include a pressurizing member 1310 that pressurizes a lowermost solid detergent arranged in the third direction Z among a plurality of solid detergents stacked in the third direction Z to move it to the outside of the storage chamber 1200 .

[0224] The pressurizing member 1310 may include a cam member that pressurizes the solid detergent by rotating. Hereinafter, the pressurizing member 1310 is referred to as the cam member 1310 .

[0225] The cam member 1310 may include a pressurizing portion 1312 a protruding from an edge of the cam member 1310 and configured to pressurize the solid detergent while being rotated by the rotation of the cam member 1310 .

[0226] The pressurizing portion 1312a may be configured to rotate and move toward the inside of the storage chamber 1200 as the cam member 1310 rotates, and to move the solid detergent to the discharge port 1210 by pressurizing one of the plurality of solid detergents stacked along the third direction Z and arranged at the lowermost end in the third direction Z. The cam member 1310 may pressurize the solid detergent along the rotation direction of the cam member 1310, thereby moving the solid detergent.

[0227] For the sake of convenience, the rotation direction of the cam member 1310 and the left and right sides described below will be referred to as Figure 8 The illustrated state is used as a reference for explanation. Figure 8 The right side of can be Figure 1 The direction corresponding to the left side of Figure 8 The left side is Figure 1 The direction corresponding to the right side of , in the second direction Y, Figure 1 The left, right and Figure 8 The left and right sides in the example can be opposite to each other, but for the sake of convenience, Figure 8 The left and right sides shown are used as references for explanation.

[0228] In addition, the cam member 1310 described below will be Figure 8 The cam member 1310 of the ejector 1300 disposed on the left side is used as an example for explanation with reference to the second direction Y shown.

[0229] When the cam member 1310 rotates clockwise, the ejector 1300 is arranged at the lower portion of the storage chamber 1200, whereby the cam member 1310 can move the solid detergent disposed on the lower surface 1220 of the storage chamber 1200 to the right side of the storage chamber 1200 while rotating in the clockwise direction.

[0230] In order to discharge the solid detergent moved to the right side to the outside of the storage chamber 1200 , the storage chamber discharge port 1210 may be provided to be arranged at a lower portion of the right side surface 1230 of the storage chamber 1200 .

[0231] The storage chamber 1200 may include a through portion 1221 formed at a lower surface 1220 of the storage chamber 1200 and configured to move the pressurizing portion 1312 a from the outside of the storage chamber 1200 to the inside of the storage chamber 1200 .

[0232] The through portion 1221 may be provided to extend not only to the lower surface 1220 of the storage chamber 1200 but also to lower portions of the right side surface 1230 and the left side surface 1240 of the storage chamber 1200 .

[0233] The pressurizing portion 1312a can rotate by the rotation of the cam component 1310 and move to the interior of the storage chamber 1200 through the lower portion of the left side surface 1240 and the through portion 1221 of the lower surface 1220, and can move to the outside of the storage chamber 1200 through the lower portion of the right side surface 1230 and the through portion 1221 of the lower surface 1220 as the cam component 1310 rotates.

[0234] At this time, the pressurizing portion 1312a may be configured to rotate while pressurizing the solid detergent placed on the lower surface 1220, thereby moving the solid detergent to the right.

[0235] like Figure 7 As shown, the through portion 1221 may be provided to open at least a portion of the lower surface 1220. Since at least a portion of the lower surface 1220 is open, the cam member 1310 disposed at the lower side of the storage chamber 1200 may rotate while moving the pressurizing portion 1312a to the inside of the storage chamber 1200 through the through portion 1221.

[0236] The through portion 1221 may be configured to open only at least a portion of the lower surface 1220 instead of opening the entire lower surface 1220 .

[0237] As an example, the lower surface 1220 may be configured such that the area where the through portion 1221 is formed is formed smaller than the area of ​​the lower surface 1222 that is closed in the third direction Z. Hereinafter, the lower surface 1222 that is closed in the third direction Z is referred to as a support surface 1222. This is because the support surface 1222 supports the solid detergent that is located at the bottom in the third direction Z.

[0238] As an example, the through portion 1221 may be provided to extend from the center of the lower surface 1220 in the first direction X along the second direction Y. Thus, the front and rear of the through portion 1221 in the first direction X may be provided as the support surface 1222 .

[0239] This is to ensure that when a plurality of solid detergents are stacked, the solid detergent located at the bottom in the third direction Z is stably located on the lower surface 1220. The support surface 1222 can support the solid detergent located at the bottom in the third direction Z so that the solid detergent is arranged adjacent to the lower surface 1220, thereby making it easy to pressurize the solid detergent when the pressurizing portion 1312a moves through the through portion 1221.

[0240] In particular, the support surface 1222 can be set in front of and behind the through portion 1221 in the first direction X, so that the support surface 1222 can be set to support the lowest solid detergent arranged in the third direction Z in the storage chamber 1200 approximately horizontally in the third direction Z.

[0241] Thus, when the solid detergent is moved to the outside of the storage chamber 1200 by the pressurizing portion 1312a, it can move in the second direction Y in a substantially horizontal state with respect to the third direction Z.

[0242] As an example, the support surface 1222 may guide the solid detergent so that the solid detergent moving in the second direction Y moves in a horizontal state relative to the third direction Z. Figure 7 As a reference, the lower surface us of the solid detergent D in the third direction Z is loaded into the storage chamber 1200 in contact with the support surface 1222. When pressurized in the second direction Y by the pressurizing portion 1312a, the lower surface us can be guided by the support surface 1222, so that the solid detergent D moves to the storage chamber discharge outlet 1210 while remaining approximately horizontal relative to the third direction Z.

[0243] When the solid detergent moves in the second direction Y in a state where it is tilted relative to the third direction Z, it may rotate or move in other directions due to the center of gravity instead of moving in the second direction Y, so that the solid detergent may not be able to move toward the storage chamber discharge outlet 1210 and cannot be discharged to the outside of the storage chamber 1200.

[0244] With respect to the cam member 1310, the edge of the cam member 1310 may include a plurality of cam regions divided in the rotation direction of the cam member 1310, based on the rotation direction of the cam member 1310. When a cam region in which an edge having the shortest radius length from the rotation axis 1313 of the cam member 1310 is arranged among the plurality of cam regions is defined as the first cam region 1310A1, the first cam region 1310A1 may be arranged at the upper end of the cam member 1310 when the dishwasher 1 is not driven to the washing stroke.

[0245] The pressing portion 1312 a may be provided to protrude at a predetermined height in a radial direction of the cam member 1310 relative to the first cam region 1310A1 .

[0246] The pressurizing portion 1312 a may be provided to protrude at a predetermined height in the radial direction of the cam member 1310 relative to the first cam region 1310A1 so that the pressure capable of transferring the solid detergent D to the storage chamber discharge port 1210 is transmitted to the solid detergent D.

[0247] The pressurizing portion 1312a can be configured to protrude at a predetermined height in the radial direction of the cam member 1310 relative to the first cam area 1310A1, so that when the cam member 1310 rotates, only the lowest solid detergent D arranged in the third direction Z is pressurized, and the solid detergent D arranged above the lowest solid detergent D is not pressurized.

[0248] As an example, the pressing portion 1312 a may be provided to protrude by 15 mm in the radial direction of the cam member 1310 relative to the first cam region 1310A1 .

[0249] The first cam region 1310A1 of the cam member 1310 may be arranged so as to be arranged at a position lower than the support surface 1222 in the third direction Z when arranged at the upper end of the cam member 1310. This is to ensure that the solid detergent located at the bottom of the plurality of solid detergents is located in the storage chamber 1200 in a substantially horizontal state relative to the third direction Z when arranged on the lower surface 1220 of the storage chamber 1200, and one side thereof is not pressed upward by the cam member 1310 based on the third direction Z.

[0250] On the contrary, Figure 8 The cam member 1310' of the ejector 1300' arranged on the right side with the second direction Y as the reference is set to Figure 8 The solid detergent loaded in the storage chamber 1200' arranged on the right side can be arranged to be discharged to the left side of the storage chamber 1200' by rotating counterclockwise based on the direction shown. This will be described in detail later.

[0251] The rotating shaft 1313 of the cam member 1310 may be arranged to extend toward the first direction X when the automatic detergent feeding device 1000 is arranged at the first position 1000A. The cam member 1310 is arranged so that the radial direction of the cam member 1310 is arranged in a direction perpendicular to the first direction X, whereby when the cam member 1310 is arranged inside the housing 1100, its volume in the first direction X can be minimized. As described above, this is to maximize the volume of the washing chamber C in the first direction X.

[0252] The ejector 1300 may include a drive motor 1320 that generates a rotational force to drive the cam member 1310. The drive motor 1320 may be arranged so that a rotation axis 1321 of the drive motor 1320 extends in a direction substantially orthogonal to the first direction X when the automatic detergent injection device 1000 is arranged in the first position 1000A. Thus, when the drive motor 1320 is arranged inside the housing 1100, the volume in the first direction X may be minimized. As described above, this is to maximize the volume of the washing chamber C in the first direction X.

[0253] The ejector 1300 may include a transmission part 1330 that transmits the rotation force generated at the driving motor 1320 to the pressurizing part 1310 .

[0254] The transmission component 1330 may include a plurality of gears. Since the rotating shaft 1313 of the cam component 1310 is arranged to extend along the first direction X, and the rotating shaft 1321 of the drive motor 1320 is arranged to extend along a direction orthogonal to the first direction X, the transmission component 1330 may include a worm gear to vertically convert the transmission direction of the driving force. As an example, the transmission component 1330 may include a bevel gear.

[0255] In the case where the transmission member 1330 includes a worm gear, it is possible to prevent the cam member 1310 from being arbitrarily rotated due to an external force.

[0256] Since the worm gear of the transmission member 1330 is arranged to extend in a direction orthogonal to the first direction X in which the rotation shaft 1313 of the cam member 1310 extends, the volume of the transmission member 1330 in the first direction X can be minimized when it is arranged inside the housing 1100. As described above, this is to maximize the volume of the washing chamber C in the first direction X.

[0257] The transmission component 1330 can transmit the rotational force generated by the drive motor 1320 to the cam component 1310 by connecting the cam component 1310 and the drive motor 1320. At this time, the transmission component 1330 can be configured to enable the cam component 1310 to rotate at an appropriate rotational speed. As an example, the transmission component 1330 can be configured to reduce the rotational speed of the rotating shaft 1321 of the drive motor 1320. The transmission component 1330 can be configured in various ways according to design factors such as the target rotational speed of the cam component 1310 and the rotational speed of the drive motor 1320.

[0258] The automatic detergent feeding device 1000 may include: a holder 1500, which is configured to keep a plurality of solid detergents in a stacked state inside the storage chamber 1200 when the automatic detergent feeding device 1000 is arranged in the first position 1000A and the second position 1000B, or moves between the first position 1000A and the second position 1000B.

[0259] The bracket 1500 may be moved in the direction in which the long side 1201 of the storage chamber 1200 extends by means of guides formed on both side surfaces 1230 and 1240 of the storage chamber 1200 .

[0260] The support 1500 may be disposed to be movable toward the plurality of solid detergents along the direction in which the plurality of solid detergents are stacked inside the storage chamber 1200. This is because the direction in which the plurality of solid detergents are stacked corresponds to the direction in which the long side 1201 of the storage chamber 1200 extends.

[0261] The support 1500 may be configured such that when the automatic detergent injection device 1000 is disposed at the first position 1000A, the support 1500 may be disposed on an upper side of a plurality of solid detergents in the storage chamber 1200 .

[0262] When automatic detergent dispenser 1000 is disposed at first position 1000A, bracket 1500 may be configured to be movable from the upper portion to the lower side of storage chamber 1200. When automatic detergent dispenser 1000 is disposed at first position 1000A, bracket 1500 may be configured to move downward inside storage chamber 1200 by gravity.

[0263] When the automatic detergent dispensing device 1000 is arranged in the first position 1000A, the stacking direction of the multiple solid detergents can correspond to the third direction Z, and the bracket 1500 can be configured to move downward based on the third direction Z by gravity, thereby pressurizing the topmost solid detergent arranged in the third direction Z among the multiple solid detergents downward.

[0264] The bracket 1500 may include a weight component configured to have a weight greater than a predetermined weight to move in the third direction Z by gravity. As an example, the weight component may be integrally configured with the bracket 1500. As an example, the weight component may be configured to be combined with the bracket 1500.

[0265] As an example, the bracket 1500 may be made of a heavy material to have a weight greater than a predetermined weight.

[0266] The support 1500 may be configured to have a weight greater than a predetermined weight, and thus may be configured to pressurize the plurality of solid detergents downward with reference to the third direction Z.

[0267] When the bottommost solid detergent among multiple solid detergents located in the third direction Z is discharged to the outside of the storage chamber 1200 by the ejector 1300, the multiple solid detergents can move downward based on the third direction Z as the stacking direction by gravity, and the bracket 1500 can pressurize the multiple solid detergents downward by gravity, so that the bracket 1500 can guide the multiple solid detergents to move downward.

[0268] As an example, when one of the multiple solid detergents stacked along the third direction Z is partially detached from the arrangement, so that a portion of the solid detergent is supported by the two side surfaces 1230 and 1240 of the storage chamber 1200 and the multiple solid detergents are restricted from moving downward, the bracket 1500 can pressurize the multiple solid detergents downward to guide the multiple solid detergents to move downward.

[0269] As described above, the automatic detergent feeding device 1000 can be configured to stack multiple solid detergents in the third direction Z when the automatic detergent feeding device 1000 is arranged in the first position 1000A, thereby improving the space efficiency of the automatic detergent feeding device 1000 and the dishwasher 1 in the first direction X and the second direction Y.

[0270] Furthermore, since the plurality of solid detergents are arranged in the direction of gravity, the automatic detergent feeding device 1000 may be configured so that the plurality of solid detergents can be easily discharged sequentially from below in the direction of gravity.

[0271] However, when the door 20 is rotated or arranged in the second position 20B from the first position 20A to the second position 20B in order to open the tub 12, the directions of the plurality of solid detergent stacks may be arranged to face a direction different from the third direction Z.

[0272] At this time, since the stacking direction of the multiple solid detergents is towards a direction different from the gravity direction, one of the multiple solid detergents may detach from the stacking structure, causing the stacking arrangement of the multiple solid detergents in the third direction Z to collapse.

[0273] As an example, as described above, the solid detergent D may be loaded into the storage chamber 1200 in a direction in which the surface of the solid detergent D formed by the lateral length d1 and the longitudinal length d2 directions is opposite to the cross-sectional area S of the storage chamber 1200 formed by the first direction X and the second direction Y.

[0274] As an example, the surface of the solid detergent D formed by the lateral length d1 and the longitudinal length d2 can be set to a curved shape instead of a conventional plane shape, whereby, when a plurality of solid detergents D are stacked, the solid detergents D opposite to each other in the stacking direction can be set to be opposite to each other with their respective curved surfaces, so that when the stacking direction of the plurality of solid detergents is toward a direction different from the direction of gravity, the plurality of solid detergents may be detached from the stacking arrangement.

[0275] That is, since it is more difficult to maintain the stacked state when the curved surfaces of the solid detergents D are stacked relative to each other, the bracket 1500 pressurizes the multiple solid detergents D along the stacking direction when the stacking direction corresponds to the gravity direction, and supports the solid detergents D to maintain the arrangement of the multiple solid detergents D when the stacking direction is different from the gravity direction.

[0276] When the stacked arrangement of multiple solid detergents collapses, even if the door 20 is arranged to the first position 20A again, the movement of the multiple solid detergents in the direction of gravity may be restricted, and the lowest solid detergent among the multiple solid detergents arranged in the third direction Z may be abnormally placed on the lower surface 1220 of the storage chamber 1200, resulting in the problem that the solid detergents cannot be discharged to the outside of the storage chamber 1200 by the ejector 1300.

[0277] The solid detergent being abnormally disposed on the lower surface 1220 means that the solid detergent is disposed at a position where it cannot be pressurized by the ejector 1300 when disposed on the lower surface 1220, or cannot move to the outside of the storage chamber 1200 even if pressurized by the ejector 1300.

[0278] To prevent this, the support 1500 may be configured to prevent the stacked arrangement of the plurality of solid detergents from collapsing when the direction in which the plurality of solid detergents are stacked is oriented in a direction different from the third direction Z due to the movement of the door 20 .

[0279] The support 1500 may be configured to maintain the stacked arrangement of the plurality of solid detergents even during a period in which the door 20 is opened at the first position 20A and moves toward the second position 20B, or when the door 20 is arranged at the second position 20B.

[0280] The support 1500 may be configured to support an uppermost solid detergent arranged in the third direction Z among the plurality of solid detergents when the direction in which the plurality of solid detergents are stacked faces a direction different from the third direction Z.

[0281] The bracket 1500 may be disposed to be fixed at a position adjacent to an uppermost solid detergent arranged in the third direction Z among the plurality of solid detergents when the direction in which the plurality of solid detergents are stacked faces a direction different from the third direction Z.

[0282] When the direction of stacking of multiple solid detergents is toward a direction different from the third direction Z, the movement of the topmost solid detergent among the multiple solid detergents arranged in the third direction Z is blocked by the temporarily fixed bracket 1500, thereby preventing the topmost solid detergent among the multiple solid detergents arranged in the third direction Z from detaching from the stacking arrangement.

[0283] The storage chamber 1200 may include a guide rail 1290 guiding the movement of the bracket 1500 inside the storage chamber 1200 .

[0284] The bracket 1500 may be guided by the guide rail 1290 to move in parallel in the extending length direction of the long side 1201 of the storage chamber 1200 .

[0285] The guide rail 1290 may be provided to enable the bracket 1500 to move downward with reference to the third direction Z when the automatic detergent dispenser 1000 is arranged at the first position 1000A.

[0286] As an example, the bracket 1500 may include a guide protrusion inserted into the guide rail 1290. The guide protrusion of the bracket 1500 may be inserted into the guide rail 1290 and move along the extending direction of the guide rail 1290.

[0287] The guide rail 1290 may be provided to extend along the extending direction of the long side 1201 of the storage chamber 1200. The bracket 1500 may be provided to be movable along the extending direction of the guide rail 1290.

[0288] The guide rail 1290 may include a clamping table 1293 configured to restrict movement of the bracket 1500 when the automatic detergent injection device 1000 is not located at the first position 1000A.

[0289] During the movement of the door 20 from the first position 20A to the second position 20B, the guide protrusion of the bracket 1500 is restricted from moving by the engaging platform 1293 , thereby restricting the movement of the bracket 1500 inside the storage chamber 1200 .

[0290] Alternatively, the rack 1500 may be configured to maintain the stacked arrangement of the plurality of solid detergents even when the door 20 is disposed in the second position 20B.

[0291] The support 1500 may be configured such that when the direction in which the plurality of solid detergents are stacked faces a direction different from the third direction Z, the support 1500 may support the uppermost solid detergent arranged in the third direction Z among the plurality of solid detergents.

[0292] The bracket 1500 may be disposed to be fixed at a position adjacent to an uppermost solid detergent arranged in the third direction Z among the plurality of solid detergents when the plurality of solid detergents are stacked in a direction different from the third direction Z.

[0293] Thus, when the direction of the stacking of multiple solid detergents is towards a direction different from the third direction Z, the bracket 1500 can be temporarily fixed inside the storage chamber 1200 by means of the clamping platform 1293, and the topmost solid detergent among the multiple solid detergents arranged in the third direction Z can be restricted from movement by the fixed bracket 1500.

[0294] Even when the direction in which multiple solid detergents are stacked is facing a direction different from the third direction Z, the stacking arrangement of the multiple solid detergents can be maintained by means of the bracket 1500. Therefore, the automatic detergent feeding device 1000 can be arranged so that when the automatic detergent feeding device 1000 is arranged in the first position 1000A, even if the multiple solid detergents are set to be stacked in the third direction Z, one of the multiple solid detergents can be discharged to the outside of the storage chamber 1200 and fed into the inside of the barrel 12.

[0295] The automatic detergent injection device 1000 may include a placement portion 1400 configured to place a solid detergent discharged from the storage chamber 1200 .

[0296] The seating portion 1400 may be disposed to communicate with the storage chamber discharge port 1210. The seating portion 1400 may include a seating portion inner space 1401 communicating with the storage chamber discharge port 1210.

[0297] One of the plurality of solid detergents may be discharged from the storage chamber 1200 through the storage chamber discharge port 1210 and move to the seating portion inner space 1401 .

[0298] The seating portion may include a discharge guide 1430 connected to the tub 12. The discharge guide 1430 may be provided as a space connected to the seating portion inner space 1401.

[0299] As an example, the seating portion internal space 1401 and the discharge guide 1430 may be formed as one space, and the seating portion internal space 1401 and the discharge guide 1430 may be divided by a seating portion opening 1420 opened and closed by a seating portion 1410 described later.

[0300] As an example, in the third direction Z, the lower end of the seating portion internal space 1401 may be formed by the seating portion opening 1420 , and the discharge guide 1430 may be a region formed downward in the third direction Z from the seating portion opening 1420 .

[0301] The seating portion 1400 may be configured such that a solid detergent moved to the seating portion inner space 1401 is temporarily seated in the seating portion 1400 and then is put into the tub 12 .

[0302] The seating portion 1400 may include a seating portion opening 1420 connecting the seating portion inner space 1401 with the discharge guide 1430 connected to the tub 12. The seating portion opening 1420 may be provided to be open toward the third direction Z when the automatic detergent injection device 1000 is arranged in the first position 1000A.

[0303] The seating portion 1400 may include a seating section 1410 that opens and closes a seating portion opening 1420. When the seating section 1410 closes the seating portion opening 1420, the seating section 1410 may be disposed to form a lower surface of the seating portion inner space 1401.

[0304] The placement section 1410 may include a placement surface 1411 for placing the solid detergent when the placement section 1410 closes the placement section opening 1420. The placement surface 1411 may be arranged to face upward in the third direction Z when the placement section 1410 closes the placement section opening 1420.

[0305] As an example, the seating portion opening 1420 may be defined by a surface closed by the seating portion 1410 in the seating portion internal space 1401. Thus, an upper region formed above the seating portion opening 1420 may be defined as the seating portion internal space 1401, and a lower region formed below the seating portion opening 1420 may be defined as the discharge guide 1430. When the seating portion 1410 closes the seating portion opening 1420, a seating surface 1411 may be arranged on the seating portion opening 1420, and accordingly, the seating surface 1411 may be defined as the lower surface of the seating portion internal space 1401.

[0306] As an example, the bottom of the seating portion inner space 1401 may be defined by the seating portion opening 1420 , but when the seating portion 1410 closes the seating portion opening 1420 , the bottom of the seating portion inner space 1401 may be defined by the seating portion 1410 .

[0307] The placement section 1410 may be configured to seal the placement section inner space 1401 from the outside when the placement section 1410 closes the placement section opening 1420 , and may be configured to connect the placement section inner space 1401 to the tub 12 when the placement section 1410 opens the placement section opening 1420 .

[0308] The seating section 1400 may include a seating section driving section 1470 configured to open and close the seating section 1410 .

[0309] As an example, the placement department driving part 1470 may include a driving motor and a transmission component.

[0310] As an example, the transmission component of the placement section driving part 1470 may include a plurality of gears. As an example, when the driving motor rotates in one direction, the plurality of gears may transmit the rotational force in one direction to the placement section 1410. The placement section 1410 may rotate in one direction by receiving the rotational force, so as to open the placement section opening 1420 from a state where the placement section 1410 closes the placement section opening 1420.

[0311] As an example, when the driving motor rotates in the opposite direction, the plurality of gears may transmit the rotational force in the opposite direction to the seating part 1410. The seating part 1410 may rotate in the opposite direction by receiving the rotational force, so as to close the seating part opening 1420 from the state where the seating part 1410 opens the seating part opening 1420.

[0312] The placement portion opening 1420 may be connected to the input port 1122 via the discharge guide 1430. A solid detergent located in the placement portion internal space 1401 may be discharged from the placement portion internal space 1401 through the placement portion opening 1420, and may be discharged from the placement portion opening 1420 through the input port 1122 to the outside of the automatic detergent input device 1000 and be input into the inside of the tub 12.

[0313] The seating portion 1400 may include a discharge guide 1430 formed between the seating portion opening 1420 and the input port 1122 and guiding the solid detergent to move from the seating portion opening 1420 to the input port 1122 .

[0314] A solid detergent discharged from the storage chamber 1200 may be temporarily placed in the placement portion 1400 . Specifically, the solid detergent may be located on a placement surface 1411 of a placement portion 1410 forming a lower surface of an internal space 1401 of the placement portion.

[0315] The inlet 1122 may be opened and closed by the inlet cover 1150 , and may be configured so that the solid detergent discharged along the discharge guide 1430 pressurizes the inlet cover 1150 and causes the inlet cover 1150 to open the inlet 1122 .

[0316] The solid detergent may pressurize the inlet cover 1150 and move into the tub 12 through the inlet 1120 .

[0317] When the placement section 1410 opens the placement section opening 1420 , the solid detergent placed on the placement section 1410 may move downward by gravity and be discharged to the outside of the placement section internal space 1401 through the placement section opening 1420 .

[0318] Automatic detergent feeder 1000 may be configured to discharge a solid detergent discharged from storage chamber 1200 to the outside of storage chamber 1200 via seating portion 1400 when the solid detergent is discharged to the outside of automatic detergent feeder 1000 instead of being immediately discharged to the outside of automatic detergent feeder 1000 .

[0319] The storage chamber 1200 may include a middle door 1250 configured to open and close the storage chamber discharge port 1210. The middle door 1250 may be configured to restrict the solid detergent loaded into the storage chamber 1200 from being discharged from the storage chamber 1200 by the ejector 1300 but moving to the seating portion 1400 by external force.

[0320] The middle door 1250 may be configured to be biased in a direction to close the storage chamber discharge port 1210. The middle door 1250 may include an elastic member 1251 and may be configured to be biased toward the storage chamber discharge port 1210 by the elastic member 1251 so that the middle door 1250 closes the storage chamber discharge port 1210.

[0321] The solid detergents among the plurality of solid detergents loaded in the storage chamber 1200 that are pressurized by the pusher 1300 and moved toward the storage chamber discharge outlet 1210 can be configured to pressurize the middle door 1250 to open the middle door 1250, and as the middle door 1250 is opened, the solid detergents can move to the seating portion 1400 through the storage chamber discharge outlet 1210.

[0322] Even if the solid detergent moves to the storage chamber discharge outlet 1210 side by external force rather than by the pressurization of the ejector 1300 , the solid detergent may be blocked by the middle door 1250 so as not to pass through the storage chamber discharge outlet 1210 and not escape from the storage chamber 1200 .

[0323] When the solid detergent moves by the pressurizing portion 1312 a and collides with the middle door 1250 , the ejector 1300 may pressurize the solid detergent so that the biased middle door 1250 is opened by the pressurization of the solid detergent.

[0324] The force with which the middle door 1250 closes the storage chamber discharge port 1210 by the elastic member 1251 may be set to be substantially smaller than the force with which the solid detergent pressurizes the door 1250 by the pressurization of the ejector 1300 .

[0325] The storage chamber discharge port 1210 may be configured not to be directly connected to the tub 12 , but to form a seating portion 1400 between the storage chamber discharge port 1210 and the tub 12 , and the storage chamber discharge port 1210 may be connected to the tub 12 through the seating portion 1400 .

[0326] When the storage chamber discharge port 1210 is directly connected to the tub 12, water remaining in the tub 12 may flow into the interior of the storage chamber 1200 through the storage chamber discharge port 1210, and thus a plurality of solid detergents loaded inside the storage chamber 1200 may be damaged or deformed by the water.

[0327] In order to prevent this, the storage chamber discharge port 1210 may be provided to be indirectly connected to the tub 12 through the seating portion 1400 instead of being directly connected to the tub 12 .

[0328] The placement part 1400 may be configured to open the placement part opening 1420 only when solid detergent is added to the tub 12, so that the internal space 1401 of the placement part is connected to the tub 12. In the step of not adding solid detergent to the inside of the tub 12, the placement part 1410 may close the placement part opening 1420 to minimize the flow of residual water in the tub 12 to the internal space 1401 of the placement part.

[0329] The seating portion 1400 may include a seating portion sensor 1440 that senses whether the solid detergent is seated in the seating portion 1400 .

[0330] Since the storage chamber 1200 is disposed to communicate with the seating portion 1400 , the solid detergent discharged from the storage chamber 1200 can certainly sense whether the solid detergent is seated in the seating portion 1400 through the seating portion sensor 1440 .

[0331] The seating portion sensor 1440 may be provided using a position sensor. As an example, the seating portion sensor 1440 may include an optical sensor.

[0332] The seating portion sensor 1440 may sense whether the solid detergent is located in the seating portion 1400, and the control device 1900 (see Figure 5 ) can control the automatic detergent feeding device 1000 based on the value sensed by the placement part sensor 1440.

[0333] The control device 1900 can receive information about whether solid detergent is loaded into the storage chamber 1200, whether the detergent is placed in the placement portion 1400 after the ejector 1300 is driven when the solid detergent is loaded into the storage chamber 1200, and whether the solid detergent is discharged from the placement portion 1400 after being placed in the placement portion 1400, and control the automatic detergent feeding device 1000 based on this.

[0334] The control device 1900 may be configured to cause the control unit to control the dishwasher 1 based on information received through communication with a main control device of the dishwasher 1 .

[0335] As an example, the control device 1900 and the main control device are lower components of the control unit, and the dishwasher 1 and the automatic detergent feeding device 1000 can be set to be controlled by the control unit. However, in the following control of the automatic detergent feeding device 1000, it is assumed that the automatic detergent feeding device 1000 is controlled by the control device 1900.

[0336] As an example, after the ejector 1300 is driven, when the placement sensor 1440 does not sense the solid detergent, the control device 1900 can determine that the solid detergent is not loaded into the storage chamber 1200 and the solid detergent is not discharged from the storage chamber 1200, or can determine that the solid detergent is loaded into the storage chamber 1200, but the solid detergent is not discharged from the storage chamber 1200 due to abnormal operation of the ejector 1300, and the automatic detergent feeding device 1000 can be controlled based on this.

[0337] As an example, control device 1900 may control ejector 1300 to drive again to move solid detergent to seating portion 1400. In addition, control device 1900 may communicate with the main control device, and the control portion may control dishwasher 1 not to perform a stroke of dishwasher 1 based on the communication value.

[0338] As an example, if the placement unit sensor 1440 continues to be unable to sense the solid detergent after the control device 1900 controls the ejector 1300 so that the ejector 1300 is driven again, the control device 1900 may communicate with the main control device, and the control unit may control the dishwasher 1 based on the communication value so as not to perform the trip of the dishwasher 1. In addition, the control unit may control the display unit to inform the user that there is no solid detergent in the storage chamber 1200.

[0339] As an example, the display part may be implemented using a display located on the main body 10 of the dishwasher 1. As an example, the display part may be implemented in a separate device configured to communicate with the dishwasher 1.

[0340] As an example, when the placement part sensor 1440 senses the solid detergent placement part and keeps the sensing state but then fails to sense the solid detergent, the control device 1900 may determine that the solid detergent has been discharged from the placement part 1400 and the solid detergent has been put into the tub 12, and based on this, the automatic detergent injection device 1000 may be controlled. As an example, the control device 1900 may communicate with the main control device, and the control part may control the dishwasher 1 based on the communication value to perform the washing stroke of the dishwasher 1.

[0341] Since the placement part sensor 1440 senses the position of the solid detergent in the placement part 1400, the control device 1900 can be set to grasp all the above-mentioned situations, so that the number of sensors that additionally sense the position of the solid detergent can be minimized. That is, the control device 1900 can judge all situations whether the solid detergent is located in the storage chamber 1200 or the placement part internal space 1401 or the outside of the placement part 1400 by only arranging the placement part sensor 1440 in the placement part 1400, without arranging a position sensor that additionally senses the position of the solid detergent in the storage chamber 1200 or the discharge guide 1430. This will be described in detail later.

[0342] As described above, the storage chamber 1200 may be provided in plurality. As an example, the storage chamber 1200 may be provided in two.

[0343] In the following, for the sake of convenience, Figure 8 As a reference, the storage chamber 1200 arranged on the left side in the second direction Y is defined as the first storage chamber 1200, and the storage chamber 1200' arranged on the right side is defined as the second storage chamber 1200'. In addition, the configuration of the first storage chamber 1200 is defined as the first configuration, and the configuration of the second storage chamber 1200' is defined as the second configuration. As an example, the middle door 1250 of the first storage chamber 1200 is defined as the first middle door 1250, and the middle door 1250' of the second storage chamber 1200' is defined as the second middle door 1250'.

[0344] In addition, the ejector for discharging the solid detergent stored in the first storage chamber 1200 is defined as a first ejector 1300, and the ejector for discharging the solid detergent stored in the second storage chamber 1200' is defined as a second ejector 1300'. In addition, the bracket 1500 disposed inside the first storage chamber 1200 is defined as a first bracket 1500, and the bracket 1500 disposed inside the second storage chamber 1200' is defined as a second bracket 1500'.

[0345] The first storage chamber 1200 and the second storage chamber 1200' may be arranged to be spaced apart in the second direction Y. When the automatic detergent feeding device 1000 is arranged in the first position 1000A, the first storage chamber 1200 and the second storage chamber 1200' respectively include long sides extending toward the third direction Z, so the first storage chamber 1200 and the second storage chamber 1200' can be effectively arranged inside the automatic detergent feeding device 1000 only if they are spaced apart in the second direction Y.

[0346] When the user loads solid detergent into the automatic detergent feeding device 1000 , a larger amount of solid detergent can be loaded at one time by using the first storage chamber 1200 and the second storage chamber 1200 ′.

[0347] The seating portion 1400 may be disposed between the first storage chamber 1200 and the second storage chamber 1200 ′ in the second direction Y. As described above, the first storage chamber 1200 may be disposed in communication with the seating portion 1400 , and the second storage chamber 1200 ′ may also be disposed in communication with the seating portion 1400 .

[0348] Thus, the first storage chamber 1200 and the second storage chamber 1200 ′ may be disposed to communicate with the tub 12 through one seating portion 1400 disposed between the first storage chamber 1200 and the second storage chamber 1200 ′ in the second direction Y. As shown in FIG.

[0349] This is to minimize the expansion of the automatic detergent feeding device 1000 in the second direction Y by making the first storage chamber 1200 and the second storage chamber 1200' share the placement portion 1400. That is, when a plurality of placement portions 1400 are provided to correspond to the first storage chamber 1200 and the second storage chamber 1200', the volume of the automatic detergent feeding device 1000 in the second direction Y may increase due to the plurality of placement portions. At this time, as described above, for the automatic detergent feeding device 1000, it is provided that the first storage chamber 1200 and the second storage chamber 1200' are both connected to one placement portion 1400, so that the length of the automatic detergent feeding device 1000 in the second direction Y can be minimized.

[0350] by Figure 8 As a reference, in the second direction Y, the first storage chamber 1200 may be arranged on the left side of the seating portion 1400 , and the second storage chamber 1200 ′ may be arranged on the right side of the seating portion 1400 .

[0351] As described above, the first cam member 1310 can rotate in a clockwise direction to move the solid detergent placed on the first lower surface 1220 of the first storage chamber 1200 toward the right side of the first storage chamber 1200, and since the first storage chamber discharge outlet 1210 is arranged at the lower portion of the first right side surface 1230 of the first storage chamber 1200, the solid detergent can move to the placement portion 1400 arranged on the right side of the first storage chamber 1200.

[0352] The first cam member 1310 may be configured to rotate in a clockwise direction in conjunction with the first driving motor 1320 and the first transmission member 1330 .

[0353] On the contrary, the second cam member 1310' may rotate in the counterclockwise direction. Unlike the first ejector 1300, the second ejector 1300' may be configured to move the solid detergent loaded into the second storage chamber 1200' to the left.

[0354] The second cam member 1310 ′ may be configured to rotate in a counterclockwise direction in conjunction with the second driving motor 1320 ′ and the second transmission member 1330 ′.

[0355] The second cam member 1310' can rotate in a counterclockwise direction to move the solid detergent placed on the second lower surface 1220' of the second storage chamber 1200' toward the left side of the second storage chamber 1200', and since the second storage chamber discharge outlet 1210' is arranged at the lower part of the second left side surface 1240' of the second storage chamber 1200', the solid detergent can move to the placement portion 1400 arranged on the left side of the second storage chamber 1200'.

[0356] The second storage chamber 1200 ′ may include a second through portion 1221 ′ formed on a second lower surface 1220 ′ of the second storage chamber 1200 ′ and configured to move the second pressurizing portion 1312 a ′ from the outside of the second storage chamber 1200 ′ to the inside of the second storage chamber 1200 ′.

[0357] The second through portion 1221 ′ may be provided to extend not only to the second lower surface 1220 ′ of the second storage chamber 1200 ′ but also to lower portions of the second right side surface 1230 ′ and the second left side surface 1240 ′ of the second storage chamber 1200 ′.

[0358] The second pressurizing portion 1312a' can rotate by the rotation of the second cam component 1310', and move to the interior of the second storage chamber 1200' through the lower part of the second right side surface 1230' and the second through portion 1221' of the second lower surface 1220', and can move to the outside of the second storage chamber 1200' through the lower part of the second left side surface 1240' and the second through portion 1221' of the second lower surface 1220' as the second cam component 1310' rotates.

[0359] The second pressurizing portion 1312a' may be configured to pressurize the solid detergent disposed on the second lower surface 1220' while rotating, thereby moving the solid detergent to the left side.

[0360] The first rotation axis 1313 of the first cam member 1310 may be disposed between the first left side surface 1240 and the first right side surface 1230 of the first storage chamber 1200 in the second direction Y. As an example, the first rotation axis 1313 of the first cam member 1310 may be disposed at the center of the left side surface 1240 and the right side surface 1230 of the first storage chamber 1200 in the second direction Y.

[0361] The second rotation axis 1313' of the second cam member 1310' may be disposed between the second left side surface 1240' and the second right side surface 1230' of the second storage chamber 1200' in the second direction Y. As an example, the second rotation axis 1313' of the second cam member 1310' may be disposed in the second direction Y at the center of the second left side surface 1240' and the second right side surface 1230' of the second storage chamber 1200'.

[0362] As described above, the reason why the first rotating shaft 1313 and the second rotating shaft 1313' of the first cam member 1310 and the second cam member 1310' are respectively arranged at the center of the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y is that the first pressurizing part 1312a and the second pressurizing part 1312a' of the first cam member 1310 and the second cam member 1310' can stably support and pressurize the solid detergent when the solid detergent is rotated.

[0363] When the first rotating shaft 1313 and the second rotating shaft 1313' of the first cam component 1310 and the second cam component 1310' are respectively arranged outside the center of the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y, in the interval where the first pressurizing portion 1312a and the second pressurizing portion 1312a' penetrate the first through portion 1221 and the second through portion 1221' by the rotation of the first cam component 1310 and the second cam component 1310', the first pressurizing portion 1312a and the second pressurizing portion 1312a' may penetrate the first through portion 1221 and the second through portion 1221' by less than a predetermined length and it is difficult to stably support the solid detergent.

[0364] In the interval where the first pressurizing portion 1312a and the second pressurizing portion 1312a' enter or leave the first storage chamber 1200 and the second storage chamber 1200' through the first through portion 1221 and the second through portion 1221', the first pressurizing portion 1312a and the second pressurizing portion 1312a' may penetrate the first through portion 1221 and the second through portion 1221' by less than a predetermined length and may be unable to stably pressurize the solid detergent loaded in the first storage chamber 1200 and the second storage chamber 1200'.

[0365] In order to prevent this situation, the first rotating axis 1313 and the second rotating axis 1313' of the first cam component 1310 and the second cam component 1310' can be set to be arranged in the center of the first storage chamber 1200 and the second storage chamber 1200' respectively in the second direction Y, so that the first pressurizing portion 1312a and the second pressurizing portion 1312a' enter or leave the first storage chamber 1200 and the second storage chamber 1200' through the first through portion 1221 and the second through portion 1221', and the first pressurizing portion 1312a' and the second pressurizing portion 1312a' are penetrated and rotated with a predetermined length or more.

[0366] In addition, when the first rotating shaft 1313 and the second rotating shaft 1313' of the first cam component 1310 and the second cam component 1310' are not arranged at the center of the first storage chamber 1200 and the second storage chamber 1200' respectively in the second direction Y, since the volume of the automatic detergent feeding device 1000 in the second direction Y will increase, preferably, the first rotating shaft 1313 and the second rotating shaft 1313' of the first cam component 1310 and the second cam component 1310' can be arranged at the center of the first storage chamber 1200 and the second storage chamber 1200' respectively in the second direction Y.

[0367] The first ejector 1300 and the second ejector 1300 ′ may be configured to be driven in mirror-symmetrical directions with the seating portion 1400 as the center in the second direction Y. The first cam member 1310 and the second cam member 1310 ′ may be configured to rotate in opposite directions to each other, thereby being mirror-symmetrical with the seating portion 1400 as the center.

[0368] Since the first storage chamber 1200 and the second storage chamber 1200' are arranged on both sides with the placement portion 1400 as the center in the second direction Y, and the solid detergent discharged from the first storage chamber 1200 and the second storage chamber 1200' need to be moved to the placement portion 1400, the first ejector 1300 and the second ejector 1300' can be driven to be mirror-symmetrical with the placement portion 1400 as the center in the second direction Y.

[0369] A width L1 (or may be referred to as a lateral length) of the first storage chamber 1200 and a width L1 of the second storage chamber 1200 ′ in the second direction Y may be set to be substantially the same.

[0370] The width L1 of the first storage chamber 1200 and the second storage chamber 1200' and the width L3 of the placement portion 1400 in the second direction Y may be set to substantially corresponding lengths. This is because when the width L3 of the placement portion 1400 in the second direction Y is formed to be much smaller than the width L1 of the first storage chamber 1200 and the second storage chamber 1200', when the solid detergent is discharged from the first storage chamber 1200 and the second storage chamber 1200' to the placement portion 1400, it may not be placed on the placement portion 1410 and be stuck in the internal space 1401 of the placement portion.

[0371] On the contrary, when the width L3 of the accommodation portion 1400 in the second direction Y is formed to be much larger than the width L1 of the first storage chamber 1200 and the second storage chamber 1200', the volume of the accommodation portion 1400 in the second direction Y increases more than necessary, which may cause the problem that the volume of the automatic detergent dispensing device 1000 in the second direction Y increases more than necessary.

[0372] Therefore, as described above, the width L3 of the seating portion 1400 is preferably formed to have a length corresponding to the width L1 in the second direction Y of the first storage chamber 1200 and the second storage chamber 1200 ′ having a cross-sectional area S in consideration of the size of the solid detergent.

[0373] Hereinafter, the driving of automatic detergent dispenser 1000 will be described in detail.

[0374] Figure 8 1 is a diagram showing a state where a part of the automatic detergent feeding device of a dishwasher according to an embodiment is removed. Fig. 9 It is shown Figure 8 A diagram of a state in which the solid detergent loaded into the first storage chamber is discharged from the first storage chamber, Fig.10 It is shown Fig. 9 A diagram showing a state in which the solid detergent is placed in the placement portion, Fig.11 It is shown Fig.10 A diagram showing a state in which solid detergent is discharged from an automatic detergent feeding device. Fig.12 It is shown Figure 8 A diagram of a state in which the solid detergent loaded into the second storage chamber is discharged from the second storage chamber.

[0375] like Figure 8 and Fig. 9 As shown, the control device 1900 may control the first ejector 1300 or the second ejector 1300 ′ to move one of the plurality of solid detergents stacked in one of the first storage chamber 1200 and the second storage chamber 1200 ′ toward the seating portion 1400 .

[0376] As an example, the control device 1900 may control the first ejector 1300 to drive the first ejector 1300. The control device 1900 may control the first ejector 1300 to drive the first ejector 1300 again based on the sensing value of the seating sensor 1440, or may control the second ejector 1300' to drive the second ejector 1300', which will be described in detail later.

[0377] The control device 1900 may control the first ejector 1300 to drive the first driving motor 1320 to rotate the first cam member 1310 in the clockwise direction.

[0378] The control device 1900 may control the second ejector 1300 ′ to drive the second driving motor 1320 ′ to rotate the second cam member 1310 ′ in a clockwise direction.

[0379] The control device 1900 may control the position of the first cam member 1310 so that the first cam region 1310A1 of the first cam member 1310 is disposed at the upper end in the third direction Z before the first pressurizing portion 1312a moves into the storage chamber 1200 due to the rotation of the first cam member 1310 .

[0380] When the first cam region 1310A1 of the first cam member 1310 is arranged at the upper end of the first cam member 1310 in the third direction Z, as described above, the first cam region 1310A1 may be arranged at the lower side of the first supporting surface 1222 of the first storage chamber 1200 in the third direction Z. Thus, the lowermost solid detergent in the third direction Z among the plurality of solid detergents loaded into the first storage chamber 1200 may be stably placed on the first supporting surface 1222, so that the first pressurizing portion 1312a may stably move the solid detergent in the second direction Y by the rotation of the first cam member 1310.

[0381] As an example, this is because, when a portion of the first cam component 1310 protrudes higher than the first support surface 1222 in the third direction Z through the first through portion 1221, the solid detergent located at the bottom in the third direction Z among the multiple solid detergents loaded into the first storage chamber 1200 cannot be arranged horizontally in the third direction Z. As a result, when the solid detergent moves in the second direction Y, it may rotate or move in other directions instead of moving in the second direction Y due to the center of gravity, thereby causing the solid detergent to be unable to move toward the first storage chamber discharge port 1210 and unable to be discharged to the outside of the first storage chamber 1200.

[0382] Thus, the control device 1900 can control the position of the first cam member 1310 so that the first cam area 1310A1 of the first cam member 1310 is arranged at the upper end in the third direction Z when the dishwasher 1 is not driven in the washing stroke. Then, when the dishwasher 1 is driven in the washing stroke, it can communicate with the main control device, and the control device 1900 can control the first ejector 1300 based on the communication value so that the first cam member 1310 rotates in the clockwise direction.

[0383] The first pressurizing portion 1312a can be linked and moved into the first storage chamber 1200 by the rotation of the first cam member 1310, thereby allowing the bottom solid detergent in the third direction Z to move to the right with reference to the second direction Y by the first pressurizing portion 1312a.

[0384] The solid detergent may be pressurized and moved to the first storage chamber discharge port 1210 by the first pressurizing part 1312a, and may be discharged to the outside of the first storage chamber 1200 through the first storage chamber discharge port 1210 as the first middle door 1250 closing the first storage chamber discharge port 1210 is opened.

[0385] Then, if Fig.10 As shown, the solid detergent may be arranged on the seating portion 1400 , and more specifically, may be located on the seating portion 1410 .

[0386] The seating section sensor 1440 may sense the position of the solid detergent to sense whether the solid detergent is located in the seating section inner space 1401. In detail, the seating section sensor 1440 may be disposed on the seating section 1410 in the third direction Z and sense whether the solid detergent is located on the seating section 1410.

[0387] The control device 1900 may receive the information that the solid detergent is placed on the seating part 1410 through the seating part sensor 1440 and communicate with the main control device, and the control part may control the dishwasher 1 based on the communicated value so that the dishwasher 1 performs a washing process.

[0388] As an example, the washing process of the dishwasher 1 may be divided into a preliminary washing step, a main washing step, a rinsing step, and a drying step. The control unit may control the dishwasher 1 based on the communication value so that the dishwasher 1 performs the preliminary washing step.

[0389] As an example, when the placement unit sensor 1440 does not sense solid detergent after the control device 1900 drives the first ejector 1300 once, the control device 1900 may send information that the solid detergent is not sensed to the main control device, and the control unit may control the dishwasher 1 based on the communicated value so that the dishwasher 1 does not perform the preparatory washing step of the washing stroke. This is because the user may open the door 20 to load the solid detergent into the automatic detergent feeding device 1000 according to the situation. Therefore, when the solid detergent is not arranged in the placement unit 1400, the control unit may control the dishwasher 1 not to start the washing stroke itself.

[0390] As an example, Fig.10 Differently, the control device 1900 may be configured to drive the first ejector 1300 once more when the placement unit sensor 1440 does not sense the solid detergent after the first ejector 1300 is driven once. As described above, at this time, the control unit may control the dishwasher 1 so that the dishwasher 1 does not perform the washing process.

[0391] This is for the purpose of driving the first ejector 1300 again to move the solid detergent in the second direction Y by means of the first pressurizing portion 1312a, so that it is discharged to the outside of the first storage chamber 1200, when the bottom solid detergent among the multiple solid detergents loaded into the first storage chamber 1200 in the third direction Z is not stably placed on the first support surface 1222 and cannot be moved in the second direction Y by means of the first pressurizing portion 1312a but moves in other directions, thereby making it unable to move to the first storage chamber discharge outlet 1210.

[0392] Then, the control device 1900 may receive the information that the solid detergents located on the seating part 1410 are set through the seating part sensor 1440 and communicate with the main control device, and the control part may control the dishwasher 1 based on the communicated value so that the dishwasher 1 performs a washing process.

[0393] like Fig.11 As shown, the control device 1900 can open the placement part 1410 when the dishwasher 1 is driven by the control part to the main wash step in the washing cycle, so that the solid detergent is discharged from the internal space 1401 of the placement part and is put into the inside of the barrel 12 through the discharge guide 1430.

[0394] The seating section 1410 may open the seating portion opening 1420 , and the solid detergent may move to the discharge guide 1430 through the seating portion opening 1420 and be discharged from the automatic detergent feeding device 1000 through the feeding port 1122 along the discharge guide 1430 .

[0395] As an example, the seating section 1410 may rotate downward to open the seating section opening 1420 , and the solid detergent placed on the seating section 1410 may move downward together with the rotation of the seating section 1410 and move to the discharge guide 1430 through the seating section opening 1420 .

[0396] The control device 1900 may rotate the seating section 1410 to open the seating section opening 1420 , and after a predetermined time has passed, may rotate the seating section 1410 in the opposite direction to reclose the seating section opening 1420 .

[0397] This is because, when the seating portion opening 1420 is opened for a predetermined time, water may flow from the tub 12 to cause water to flow into the storage chamber 1200 through the seating portion 1400. To prevent this, the control device 1900 may control the opening and closing of the seating portion 1410.

[0398] The control device 1900 can control the placement section driving unit 1470 to open and close the placement section 1410. The placement section driving unit 1470 can drive the placement section 1410 according to the control of the control device 1900 to transmit a rotational force in one direction or in the opposite direction to the placement section 1410 so that the placement section 1410 opens and closes the placement section opening 1420.

[0399] The control device 1900 can communicate with the main control device after controlling the placement section 1410 to open and close the placement section 1410, when receiving information from the placement section sensor 1440 that the solid detergent is not located in the placement section 1400, and the control section can control the dishwasher 1 based on the communicated value so that the dishwasher 1 performs the main washing step in the washing cycle.

[0400] This is to prevent the dishwasher 1 from performing the main washing step in a state where the solid detergent may not be separated from the seating portion internal space 1401 due to the solid detergent adhering to the seating portion 1410 even if the seating portion 1410 opens and closes the seating portion opening 1420 .

[0401] The control device 1900 can control the placement section 1410 by opening and closing the placement section 1410, receive information from the placement section sensor 1440 that the solid detergent is not located in the placement section 1400, and control the position of the first cam member 1310 so that the first cam area 1310A1 of the first cam member 1310 is arranged at the upper end in the third direction Z.

[0402] Thus, as the bottommost solid detergent among the multiple solid detergents located in the third direction Z can be discharged to the outside of the first storage chamber 1200, the multiple solid detergents loaded in the first storage chamber 1200 can move downward and the solid detergents located immediately above the discharged solid detergents can be stably arranged on the support surface 1222.

[0403] The control device 1900 may control the automatic detergent feeding device 100 to automatically feed solid detergent into the tub 12 when the dishwasher 1 is driven in a washing stroke by repeating the above process.

[0404] After driving the first ejector 1300, the control device 1900 may, as described above, additionally drive the first ejector 1300 and then receive information from the seating portion sensor 1440 regarding whether solid detergent is sensed after receiving information from the seating portion sensor 1440 that solid detergent is not sensed.

[0405] At this time, when the control device 1900 receives information that the solid detergent is not sensed from the seating portion sensor 1440 after the control device 1900 additionally drives the first ejector 1300, the control device 1900 may be configured to drive the second ejector 1300' based on this information.

[0406] This is because, after the control device 1900 controls the first ejector 1300 to drive the first ejector 1300 twice, if the seating portion sensor 1440 still does not sense the solid detergent, the plurality of solid detergents loaded into the first storage chamber 1200 may have all been discharged from the first storage chamber 1200 .

[0407] Thus, the control device 1900 can control the second ejector 1300' to drive the second ejector 1300'. Since the features of the control device 1900 driving the second ejector 1300' are the same as the features of the control device 1900 driving the first ejector 1300, repeated descriptions are omitted.

[0408] In addition, if Fig.10 and Fig.11 As shown, after the pressurizing portion 1312a pressurizes the bottommost solid detergent among multiple solid detergents by rotating the cam part 1310, as the pressurizing portion 1312a detaches from the outside of the storage chamber 1200, the multiple solid detergents can move downward in parallel with the third direction Z as a reference in a stacked state.

[0409] The cam member 1310 may be configured to guide the plurality of solid detergents stacked and loaded inside the storage chamber 1200 to move parallel to the third direction Z. More specifically, it may be configured to guide the plurality of solid detergents placed at the edge of the cam member 1310 to gradually descend inside the storage chamber as the cam member 1310 rotates as the cam member 1310 rotates.

[0410] Above, refer to Figures 1 to 12 , the structure and operation of the automatic detergent feeding device 1000 of the dishwasher 1 according to an embodiment of the present disclosure are described. However, the concept of the present disclosure is not limited thereto, and the above description is only an example of a dishwasher and an automatic detergent feeding device thereof according to the concept of the present disclosure.

[0411] For example, multiple solid detergents can be arranged so that when the automatic detergent feeding device 1000 is located in the first position 1000A, inside the storage chamber 1200, multiple solid detergents can be stacked and loaded in a direction different from the third direction Z (i.e., a direction different from the up and down direction of the dishwasher 1).

[0412] As an example, when the automatic detergent injection device 1000 is located at the first position 1000A, the automatic detergent injection device 1000 may include a storage chamber having a long side extending along the second direction Y as the left-right direction of the dishwasher 1, and a plurality of solid detergents may be arranged to be stacked and loaded in the second direction Y inside the storage chamber. The automatic detergent injection device 1000 may include a holder for moving a plurality of solid detergents stacked in the second direction Y inside the storage chamber in the second direction Y, for example, the holder may include an elastic member to move the plurality of solid detergents toward a cam member of an ejector in the second direction Y. The cam member may pressurize one of the plurality of solid detergents to move it to the outside of the storage chamber, for example, it may be discharged in a direction orthogonal to the second direction Y and moved to the bottom of the storage chamber. A solid detergent discharged to the outside of the storage chamber may be injected into the barrel 12 by a placement portion or the like.

[0413] Or, as an example, Figures 1 to 12 As shown, when the automatic detergent feeding device 1000 is located at the first position 1000A, the automatic detergent feeding device 1000 may include storage chambers 1200, 1200' configured to allow a plurality of solid detergents to be stacked and loaded in the third direction Z. Figures 1 to 12Differently as shown, the automatic detergent injection device 1000 can be configured to move a plurality of solid detergents upward and discharge them inside the storage chambers 1200 and 1200'. The automatic detergent injection device 1000 may include a bracket arranged inside the storage chambers 1200 and 1200' and moving a plurality of solid detergents upward, for example, the bracket may include an elastic component to move a plurality of solid detergents upward. A cam of an ejector may be arranged on the upper side of the storage chambers 1200 and 1200', and the solid detergent arranged at the top of the plurality of solid detergents may be moved to the outside of the storage chamber 1200 by means of the cam of the ejector. A solid detergent moved to the outside of the storage chamber 1200 may be injected into the barrel 12 by a placement portion or the like.

[0414] In addition, it is described that when the automatic detergent feeding device 1000 is located at the first position 1000A, a plurality of solid detergents are stacked and loaded in the third direction Z as the up-down direction inside the storage chamber 1200, 1200', wherein the term "third direction" referring to the direction in which the plurality of solid detergents are stacked and loaded inside the storage chamber 1200, 1200' is only a term used to define the stacking direction of the plurality of solid detergents, and the interpretation of the stacking direction of the plurality of solid detergents is not limited by the expression "third" and the like. For example, as required, the stacking direction of the plurality of solid detergents can be referred to as the "first direction", in which case the term "first direction" can also be interpreted as referring to the Z direction shown in the figure according to the embodiment of the present disclosure (provided that the automatic detergent feeding device 1000 is located at the first position 1000A), etc. Below, the bracket 1500 is described in detail.

[0415] Fig.13 is a diagram showing a portion of a storage chamber and a bracket when the automatic detergent feeding device in a dishwasher according to an embodiment is arranged in a first position, Fig.14 It is briefly shown Fig.13 Figure 1 shows a portion of the guide rail and bracket. Fig.15 is a diagram showing a portion of a storage chamber and a bracket when the automatic detergent feeding device in a dishwasher according to an embodiment is arranged in a second position, Fig.16 It is briefly shown Fig.15 Figure 2 shows a portion of the guide rail and bracket.

[0416] As an example, the bracket 1500 may be provided as a plurality of brackets 1500, 1500' in a number corresponding to the plurality of storage chambers 1200, 1200'. Fig.13 As shown, the description is made based on a bracket 1500.

[0417] As described above, the storage chamber 1200 may include the guide rail 1290 guiding the movement of the bracket 1500 inside the storage chamber 1200 .

[0418] like Fig.13 and Fig.14 As shown, the guide rail 1290 may be arranged to extend in the direction in which the plurality of solid detergents are stacked. The guide rail 1290 may be arranged to extend in the direction in which the long side 1201 of the storage chamber 1200 extends. The guide rail 1290 may be arranged to extend in the third direction Z as the up-down direction when the automatic detergent feeding device 1000 is arranged in the first position 1000A.

[0419] As described above, the bracket 1500 may include the guide protrusion 1510 disposed to be inserted into the guide rail 1290 and movable in the extending direction of the guide rail 1290 .

[0420] As an example, the guide rail 1290 may be formed on the right side surface 1230 and the left side surface 1240 of the storage chamber 1200 to be provided as a pair. As an example, the guide rail 1290 may be provided to be formed on the inner surface 1260 of the storage chamber 1200.

[0421] As an example, the guide protrusions 1510 may be provided as a pair corresponding to the pair of guide rails 1290. The pair of guide protrusions 1510 may protrude to the left and right sides from the bracket 1500 to be inserted into the guide rails 1290 formed on the right side surface 1230 and the guide rails 1290 formed on the left side surface 1240, respectively.

[0422] The bracket 1500 may be disposed to move in parallel within the storage chamber 1200 along a direction in which the long side 1201 of the storage chamber 1200 extends.

[0423] Taking the long side 1201 of the storage chamber 1200 as a reference, the ejector 1300 may be arranged on one side 1201a of the long side 1201 (refer to Figure 7 ), the bracket 1500 can move from the other side 1201b of the long side 1201 along the extension direction of the long side 1201 toward the one side 1201a of the long side 1201.

[0424] The support 1500 may be configured such that when the direction in which the multiple solid detergents are stacked corresponds to the third direction Z, the support 1500 may move toward the multiple solid detergents from the other side 1201b of the long side 1201 by gravity, thereby pressurizing the multiple solid detergents in the direction in which the multiple solid detergents are stacked.

[0425] The support 1500 may be configured to pressurize the uppermost solid detergent Dh in the third direction Z among the plurality of solid detergents by gravity. The plurality of solid detergents may be configured to receive external force pressed by the support 1500 in the stacking direction and thereby maintain the plurality of solid detergents in a stacked arrangement.

[0426] The guide rail 1290 may include a first side 1291 extending in parallel with an extension direction of the guide rail 1290 and a second side 1292 disposed spaced apart from the first side 1291 in a direction orthogonal to the extension direction of the guide rail 1290 .

[0427] A guide groove 1294 may be formed between the first side 1291 and the second side 1292 , and it may be configured such that the guide protrusion 1510 is inserted into the guide groove 1294 .

[0428] When the direction in which the plurality of solid detergents are stacked is oriented toward a direction different from the third direction Z due to the opening of the door 20 , the second side 1292 may be disposed at a lower side of the first side 1291 in the third direction Z.

[0429] The second side 1292 may be disposed in front of the first side 1291 in the first direction X. Thus, the second side 1292 may be disposed at a lower side of the first side 1291 in the third direction Z when the door 20 is opened.

[0430] The engaging table 1293 may be disposed on the second side 1292. The engaging table 1293 may be configured to restrict movement of the bracket 1500 in the direction of the plurality of solid detergent stacks when the direction of the plurality of solid detergent stacks is oriented in a direction different from the third direction Z due to the opening of the door 20.

[0431] As an example, the clamping stage 1293 may be provided to protrude in a direction from the second side 1292 toward the first side 1291 .

[0432] As an example, the engaging platform 1293 may include a guide portion 1293a extending obliquely relative to the second side 1292 and a support portion 1293b extending from the guide portion 1293a toward the second side 1292. The guide portion 1293a may be arranged so that when the automatic detergent feeding device 1000 is arranged in the first position 1000A, the guide portion 1293a may be arranged on the upper side of the support portion 1293b.

[0433] When automatic detergent dispenser 1000 is disposed at first position 1000A, guide portion 1293a may be provided to extend obliquely downward from second side 1292. Support portion 1293b may be provided to extend from a lower end of guide portion 1293a in third direction Z toward second side 1292.

[0434] The support portion 1293b may be configured to extend from a lower end of the guide portion 1293a in the third direction Z toward the second side 1292 such that an inclination angle of the support portion 1293b based on the second side 1292 is greater than an inclination angle of the guide portion 1293a.

[0435] When the automatic detergent dispenser 1000 is disposed at the first position 1000A, the bracket 1500 may move downward by gravity, and the guide protrusion 1510 may move downward along the guide groove 1294 .

[0436] As an example, the guide protrusion 1510 may move downward along the guide groove 1294 without contacting the first side 1291 and the second side 1292 .

[0437] As an example, when the guide protrusion 1510 moves toward the first side 1291 , the guide protrusion 1510 may be guided by the first side 1291 and move downward.

[0438] As an example, when the guide protrusion 1510 moves toward the second side 1292 , the guide protrusion 1510 may be guided by the guide portion 1293 a to move downward.

[0439] When the automatic detergent feeding device 1000 is arranged in the first position 1000A, the bracket 1500 can move downward from the other side 1201b of the long side 1201 along the guide rail 1290 based on the third direction Z, thereby pressurizing one solid detergent Dh located closest to the bracket 1500 among the multiple solid detergents, thereby maintaining the stacking arrangement of the multiple solid detergents. In addition, when the solid detergent arranged at the bottom among the multiple solid detergents is discharged to the outside of the storage chamber 1200 by the ejector 1300, the bracket 1500 can also continuously pressurize one solid detergent Dh located closest to the bracket 1500, so that the multiple solid detergents move downward in a state of maintaining the stacking arrangement of the multiple solid detergents.

[0440] The bracket 1500 may include a flange 1520 extending from one side of the bracket 1500 toward the plurality of solid detergents in a direction in which the plurality of solid detergents are stacked.

[0441] The flange 1520 may be disposed to overlap a portion of a solid detergent Dh located closest to the bracket 1500 among the plurality of solid detergents in the stacking direction of the plurality of solid detergents.

[0442] As an example, the flange 1520 may extend downward from a lower end of the side of the bracket 1500 facing the inner surface 1260 of the storage chamber 1200 .

[0443] The flange 1520 may be disposed to be in contact with the inner surface 1260 of the storage chamber 1200 .

[0444] When the rack 1500 moves in the stacking direction of the plurality of solid detergents, the flange 1520 may move between one solid detergent Dh located closest to the rack 1500 and the inner surface 1260 of the storage chamber 1200 .

[0445] The flange 1520 may be provided to stably arrange the bracket 1500 in the third direction Z on one solid detergent Dh located closest to the bracket 1500 .

[0446] The flange 1520 may be configured to contact and move with the inner surface 1260 of the storage chamber 1200 when the bracket 1500 moves, thereby preventing the bracket 1500 from rotating or moving in other directions than the stacking direction of the plurality of solid detergents during the movement.

[0447] The bracket 1500 may include a handle 1530 extending from the bracket 1500 toward the storage chamber discharge port 1210 .

[0448] As described above, the rack 1500 is disposed to move toward the lower portion of the storage chamber 1200 in the third direction Z, and when a plurality of solid detergents loaded into the storage chamber 1200 are all discharged, the rack 1500 may move to the lower surface 1220 of the storage chamber 1200 .

[0449] The bracket 1500 can move toward the lower part of the storage chamber 1200 in the third direction Z by gravity, but cannot move toward the upper part of the storage chamber 1200 without generating an external force due to the clamping platform 1293 .

[0450] Therefore, when a plurality of solid detergents loaded into the storage chamber 1200 are all discharged, the bracket 1500 may be arranged at the lower surface 1220 of the storage chamber 1200 and may maintain its position.

[0451] When all the solid detergents loaded into the storage chamber 1200 are discharged and the user loads new solid detergents into the storage chamber, the user can easily move the rack 1500 to the other side 1201 b of the long side 1201 by holding the handle 1530 .

[0452] The storage chamber 1200 may include an auxiliary rail 1295 that guides movement of the bracket 1500 inside the storage chamber 1200 and is spaced apart from the guide rail 1290. When the automatic detergent dispenser 1000 is disposed in the first position 1000A, the auxiliary rail 1295 may be spaced apart from the guide rail 1290 in the first direction X.

[0453] The auxiliary guide rail 1295 may extend in the same extending direction as the guide rail 1290. The auxiliary guide rail 1295 may be provided to extend along an extending direction of the long side 1201 of the storage chamber 1200.

[0454] The bracket 1500 may include an auxiliary guide protrusion 1540 inserted into the auxiliary guide rail 1295. The auxiliary guide protrusion 1540 may be inserted into the auxiliary guide rail 1295 and move along an extending direction of the auxiliary guide rail 1295.

[0455] The auxiliary guide rail 1295 may include two sides extending in parallel along an extension direction of the auxiliary guide rail 1295 and an auxiliary guide groove formed between the two sides, and the auxiliary guide protrusion 1540 may be guided by the auxiliary guide rail 1295 in a manner of being inserted into the auxiliary guide groove and linearly moved.

[0456] The bracket 1500 may include a weight component 1550 having a weight greater than a predetermined weight to move by gravity in the third direction Z. As an example, the weight component 1550 may be integrally provided with the bracket 1500. As an example, the weight component 1550 may be provided in combination with the bracket 1500.

[0457] As an example, the bracket 1500 may be configured using a heavier material to have a weight greater than a predetermined weight without including the weight component 1550 .

[0458] The support 1500 may be configured to have a weight greater than a predetermined weight, and thus configured to pressurize the plurality of solid detergents downward with reference to the third direction Z.

[0459] like Fig.15 and Fig.16 As shown, when the stacking direction of the plurality of solid detergents is toward a direction different from the third direction Z due to the opening of the door 20, the bracket 1500 can be configured to be restricted by the clamping table 1293 in the movement in the stacking direction of the plurality of solid detergents and stop at a specific position.

[0460] Thus, since it is configured to block the movement of a solid detergent Dh located closest to the bracket 1500 among the multiple solid detergents, and the movement of the solid detergent Dh located at the top is restricted, the solid detergent D1 located at the top restricts the movement of the other multiple solid detergents, thereby maintaining the stacking arrangement of the multiple solid detergents.

[0461] When the direction of the stacking of the plurality of solid detergents is oriented in a direction different from the third direction Z due to the opening of the door 20, the bracket 1500 may be configured to support the uppermost solid detergent Dh among the plurality of solid detergents, thereby maintaining the stacking arrangement of the plurality of solid detergents.

[0462] When the direction of multiple solid detergent stacks is towards a direction different from the third direction Z due to the opening of the door 20, the guide protrusion 1510 can be supported by the support portion 1293b, thereby limiting the guide protrusion 1510 from moving toward the other side 1201b of the long side 1201 by the movement of the door 20.

[0463] The guide protrusion 1510 can be configured to move toward one side 1201a of the long side 1201 by the weight of the bracket 1500, and according to circumstances, an external force can be applied to the other side 1201b of the long side 1201 by the rotation of the door 20. At this time, the bracket 1500 can be configured to be restricted by the support portion 1293b to move toward the other side 1201b of the long side 1201, so that the bracket 1500 cannot move toward the other side 1201b of the long side 1201.

[0464] Even if the extension direction of the long side 1201 is toward a direction different from the third direction Z due to the opening of the door 20, the bracket 1500 is continuously applied with an external force toward one side 1201a of the long side 1201 by gravity, and the movement toward the other side 1201b of the long side 1201 is restricted, thereby maintaining a stopped state on the upper side of the topmost solid detergent Dh among the multiple solid detergents located in the third direction Z.

[0465] Thus, when an external force is applied to a solid detergent Dh located at the top among a plurality of solid detergents in a direction other than the side 1201a of the long side 1201 due to the opening of the door 20, the bracket 1500 can remain in a stopped state on the upper side of the solid detergent Dh in the third direction Z, so that the solid detergent Dh is supported by the bracket 1500.

[0466] The support 1500 may block the movement of the uppermost solid detergent Dh among the plurality of solid detergents, thereby preventing the solid detergent Dh from being separated from the stacked arrangement.

[0467] The bottommost solid detergent among the multiple solid detergents in the third direction Z is supported by the lower surface 1220 of the storage chamber 1200, and the topmost solid detergent Dh among the multiple solid detergents is supported by the bracket 1500, so that even if the automatic detergent dispensing device 1000 is not arranged in the first position 1000A due to the opening of the door 20, the stacking arrangement of the multiple solid detergents can be maintained.

[0468] Hereinafter, the technical features of loading a plurality of solid detergents into the automatic detergent feeding device 1000 and the storage chamber cover 1140 of the automatic detergent feeding device 1000 opened for this purpose will be described in detail.

[0469] Fig.17is a diagram showing a step of loading solid detergent into an automatic detergent feeding device of a dishwasher according to an embodiment, Fig.18 It is shown Fig.17 The following steps are shown in the figure. Fig.19 It is a side sectional view of an automatic detergent dispensing device of a dishwasher.

[0470] like Fig.17 As shown, the user may open the door 20 and load solid detergent into the storage chambers 1200 and 1200' when the automatic detergent injection device 1000 is arranged at the second position 1000B.

[0471] The user may open the first storage chamber cover 1140 and the second storage chamber cover 1140 ′ to open the first storage chamber 1200 and the second storage chamber 1200 ′.

[0472] The storage chamber covers 1140 , 1140 ′ may be provided to open and close the storage chambers 1200 , 1200 ′.

[0473] The storage chamber covers 1140, 1140' may be provided to open the storage chambers 1200, 1200' in a direction orthogonal to a stacking direction of the plurality of solid detergents.

[0474] The storage chamber openings 1121, 1121' may be opened in a direction orthogonal to a stacking direction of the plurality of solid detergents.

[0475] As described above, the storage chamber openings 1121, 1121' can be formed by the shell 1100 as a component of the shell 1100, but are not limited to this. The storage chamber openings 1121, 1121' can also be a component of the storage chambers 1200, 1200' and defined as a component of the storage chambers 1200, 1200' that open the storage chambers 1200, 1200'.

[0476] The storage chamber openings 1121 and 1121 ′ may be opened toward the first direction X when the automatic detergent feeding device 1000 is arranged at the first position 1000A.

[0477] The storage chamber covers 1140 and 1140 ′ open and close the storage chamber openings 1121 and 1121 ′, so when the automatic detergent feeding device 1000 is arranged at the first position 1000A, the storage chamber covers 1140 and 1140 ′ can be opened toward the first direction X.

[0478] When automatic detergent dispenser 1000 is arranged at second position 1000B, it may be opened toward third direction Z.

[0479] Thus, when the automatic detergent dispenser 1000 is disposed at the second position 1000B, the user can easily open the first storage chamber cover 1140 and the second storage chamber cover 1140'.

[0480] The storage chamber covers 1140 , 1140 ′ may seal the storage chambers 1200 , 1200 ′ when closing the storage chambers 1200 , 1200 ′ to prevent moisture from penetrating into the storage chambers 1200 , 1200 ′.

[0481] The storage chamber covers 1140 , 1140 ′ may be provided in a number corresponding to the number of the respective storage chambers 1200 , 1200 ′.

[0482] This is because, when the two storage chambers 1200, 1200' are configured to be opened and closed by one storage chamber cover, the storage chamber cover is configured to cover the two storage chambers 1200, 1200', resulting in an increase in the area of ​​the storage chamber cover. As a result, the sealing effect of the two storage chambers 1200, 1200' may be reduced due to the increase in the sealing area of ​​the storage chamber cover.

[0483] The first storage chamber cover 1140 may be provided to open and close the first storage chamber opening 1121 of the first storage chamber 1200. The second storage chamber cover 1140' may be provided to open and close the second storage chamber opening 1121' of the second storage chamber 1200'.

[0484] The first storage chamber cover 1140 may be provided to seal the first storage chamber opening 1121. The second storage chamber cover 1140' may be provided to seal the second storage chamber opening 1121'.

[0485] As described above, when the plurality of solid detergents loaded into the first storage chamber 1200 and the second storage chamber 1200 ′ are all discharged, the first rack 1500 and the second rack 1500 ′ may be disposed on the lower surfaces 1220 , 1220 ′ of the storage chambers 1200 , 1200 ′, respectively.

[0486] The bracket 1500 can be moved toward the lower part of the storage chamber 1200 in the third direction Z by gravity, but cannot be moved to the upper part of the storage chamber 1200 without generating external force due to the clamping platform 1293. Therefore, the user can hold the handle 1530 of the bracket 1500 and move the bracket 1500 from one side 1201a of the long side 1201 to the other side 1201b of the long side 1201.

[0487] As an example, the first storage chamber cover 1140 and the second storage chamber cover 1140' may be fully opened to load a plurality of solid detergents into each of the first storage chamber 1200 and the second storage chamber 1200'. As an example, one of the first storage chamber cover 1140 and the second storage chamber cover 1140' may be opened to load a plurality of solid detergents into one of the first storage chamber 1200 and the second storage chamber 1200'.

[0488] Then, if Fig.18 As shown, the user may load a plurality of solid detergents into the space between the first lower surface 1220 and the second lower surface 1220 ′ of the first storage chamber 1200 and the second storage chamber 1200 ′ and the first bracket 1500 and the second bracket 1500 ′.

[0489] Then, the user can move the door 20 to the closed position 20A after closing the first storage chamber cover 1140 and the second storage chamber cover 1140' to close the storage chamber 1200. Thus, the automatic detergent feeding device 1000 can be rearranged in the first position 1000A, and the brackets 1500, 1500' can be configured to pressurize the plurality of solid detergents in the third direction Z to continuously maintain the stacked arrangement of the plurality of solid detergents.

[0490] Then, even if automatic detergent dispenser 1000 is disposed at a position other than first position 1000A due to the opening of door 20, the plurality of solid detergents can be kept in a stacked arrangement by brackets 1500 and 1500'.

[0491] The storage chamber region 1141 , the cover protrusion 1142 , and the cover gasket 1144 of the storage chamber cover 1140 are described below. However, for the sake of convenience, the description is based on one storage chamber 1200 , one storage chamber opening 1121 , and one storage chamber cover 1140 .

[0492] The housing 1100 may include a cover gasket 1144 configured to maintain a seal between the storage chamber cover 1140 and the storage chamber 1200 so that the storage chamber cover 1140 can easily seal the storage chamber 1200 .

[0493] As an example, the cover gasket 1144 may be combined with the storage chamber cover 1140. As an example, the cover gasket 1144 may be combined with the storage chamber opening edge 1123 forming the storage chamber opening 1121.

[0494] As an example, the storage chamber cover 1140 may include a cover gasket coupling portion 1143 to which the cover gasket 1144 is coupled.

[0495] The cover gasket coupling portion 1143 may be provided to protrude in a direction from an inner surface 1140 a of the storage chamber cover 1140 toward the storage chamber 1200 when the storage chamber cover 1140 closes the storage chamber 1200 .

[0496] The cover gasket 1144 can be inserted and combined with the cover gasket combining portion 1143 to be combined with the cover gasket combining portion 1143.

[0497] The cover gasket coupling portion 1143 may be configured to protrude in one direction in a manner such that the cover gasket 1144 is inserted and coupled thereto, and may be formed on the storage chamber cover 1140 in order to reduce the volume of the housing 1100 .

[0498] This is because, when the cover gasket coupling portion is formed at the storage chamber opening edge 1123 , the area of ​​the housing 1100 in the first direction X may increase, thereby reducing the area of ​​the tub 12 .

[0499] The cover gasket 1144 may be configured to fit snugly against the storage chamber opening edge 1123 to seal the storage chamber opening 1121 .

[0500] The storage chamber cover 1140 may include a storage chamber area 1141 located inside a cover gasket 1144 and forming a surface of the storage chamber 1200 when the storage chamber cover 1140 closes the storage chamber opening 1121 .

[0501] The storage chamber area 1141 may be provided using an area of ​​the inner surface 1140 a of the storage chamber cover 1140 .

[0502] As an example, the storage chamber area 1141 may be configured to protrude toward the storage chamber 1200 more than the inner surface 1140 a of the storage chamber cover 1140 when the storage chamber cover 1140 closes the storage chamber opening 1121 .

[0503] As an example, considering the cross-sectional area S of the storage chamber 1200 (refer to Figure 7 ) in size, the storage chamber area 1141 can protrude in a variety of lengths.

[0504] As an example, considering the cross-sectional area S of the storage chamber 1200 (refer to Figure 7 ) in size, the storage chamber area 1141 can protrude variably.

[0505] As an example, considering the longitudinal length d2 (refer to Figure 7 ), the storage chamber area 1141 can protrude in a manner to ensure a longitudinal length L2 of an appropriate cross-sectional area S of the storage chamber 1200.

[0506] The storage chamber cover 1140 may include a cover protrusion 1142 configured to protrude from the storage chamber region 1141 toward the storage chamber 1200 when the storage chamber cover 1140 closes the storage chamber opening 1121 .

[0507] The cover protrusion 1142 may protrude from one side of the storage chamber area 1141 .

[0508] like Fig.19 As shown, when the automatic detergent dispenser 1000 is located at the first position 1000A, the cover protrusion 1142 may protrude from a lower portion of the storage chamber region 1141 in the third direction Z toward the storage chamber 1200 .

[0509] When automatic detergent dispenser 1000 is located at first position 1000A, cover protrusion 1142 may protrude obliquely from a lower portion of storage chamber region 1141 in third direction Z toward storage chamber 1200 .

[0510] At this time, the cover protrusion 1142 may be configured to gradually protrude downward in the third direction Z.

[0511] In the third direction Z, compared with the longitudinal length L2 of the cross-sectional area S of the storage chamber 1200 set by the storage chamber area 1141 in the internal space of the storage chamber 1200 where the cover protrusion 1142 is not provided, the longitudinal length L4 of the cross-sectional area S of the storage chamber 1200 set by the cover protrusion 1142 in the internal space of the storage chamber 1200 where the cover protrusion 1142 is provided can be formed shorter.

[0512] The longitudinal length L4 of the cross-sectional area S of the storage chamber 1200 set by the cover protrusion 1142 may be formed to be longer than the longitudinal length d2 of the solid detergent, and may be formed to be shorter than the longitudinal length L2 of the cross-sectional area S of the storage chamber 1200 set by the storage chamber region 1141 .

[0513] The longitudinal length of the cross-sectional area S of the storage chamber 1200 in the third direction Z may be formed such that the lower side thereof is shorter than the upper side.

[0514] When automatic detergent injection device 1000 is arranged at first position 1000A and the bottommost solid detergent among the plurality of solid detergents is injected outside storage chamber 1200, the plurality of solid detergents loaded into storage chamber 1200 may move downward by gravity.

[0515] According to the difference between the longitudinal length L2 of the cross-sectional area S of the storage chamber 1200 set by the storage chamber area 1141 and the longitudinal length d2 of the solid detergent, the plurality of solid detergents may move downward and rotate to one side, so that the stacked arrangement of the plurality of solid detergents may collapse.

[0516] In particular, when the lowest solid detergent in the third direction Z among the plurality of solid detergents is separated from the stacked arrangement, a problem may occur because it cannot be discharged to the outside of the storage chamber 1200 by the ejector 1300 .

[0517] To prevent this, the cover protrusion 1142 may be disposed below the storage chamber region 1141 in the third direction Z to reduce a longitudinal length L4 of a cross-sectional area S of a lower portion of the storage chamber 1200 based on the third direction Z.

[0518] By minimizing the distance between the longitudinal length L4 of the cross-sectional area S of the lower portion of the storage chamber 1200 in the third direction Z and the longitudinal length ds of the solid detergent by means of the cover protrusion 1142, the lowest solid detergent arranged in the third direction Z among the solid detergents moves vertically when it moves downward and cannot rotate to one side, thereby being horizontally placed on the lower surface 1222 of the storage chamber 1200.

[0519] As an example, the cover protrusion 1142 can be gradually inclined from the upper part of the storage chamber area 1141 in the third direction Z, and the protruding length of the cover protrusion 1142 at the lower part of the storage chamber area 1141 in the third direction Z can be formed to be greater than the protruding length at the upper part.

[0520] The following is a detailed description of the ejector 2300 according to an example.

[0521] Fig. 20 1 is a diagram showing a state where a part of the automatic detergent feeding device of a dishwasher according to an embodiment is removed. Fig.21 It is shown Fig. 20 A diagram of a state in which the solid detergent loaded in the first storage chamber is discharged from the first storage chamber, Fig. 22 It is shown Fig.21 A diagram showing a state in which a solid detergent is placed in a placement portion.

[0522] The ejector 2300 may be arranged at one side 1201a of the long side 1201 in the extending direction of the long side 1201. When the automatic detergent dispenser 1000 is arranged at the first position 1000A, in the third direction Z, one side 1201a of the long side 1201 may be arranged at the lower side, and the other side 1201b of the long side 1201 may be arranged at the upper side.

[0523] The ejector 2300 may be disposed at a lower portion of the storage chamber 1200 in the third direction Z to discharge a lowermost solid detergent disposed in the third direction Z among a plurality of solid detergents stacked along the third direction Z from the storage chamber 1200 .

[0524] When automatic detergent injection device 1000 is arranged at first position 1000A, ejector 2300 may discharge solid detergents located closest to lower surface 1220 of storage chamber 1200 among the plurality of solid detergents to the outside of storage chamber 1200 .

[0525] The ejector 2300 may include a pressurizing member 2310 that pressurizes a lowermost solid detergent arranged in the third direction Z among a plurality of solid detergents stacked in the third direction Z to move it to the outside of the storage chamber 1200 .

[0526] The pressurizing member 2310 may include a pusher that pressurizes the solid detergent by rotating.

[0527] For ease of description, the left and right sides of the pusher 2310 described below are Figure 8 The illustrated state is used as a reference for explanation. Fig. 20 The right side of can be Figure 1 The direction corresponding to the left side of Fig. 20 The left side of the Figure 1 The direction corresponding to the right side of , in the second direction Y, Figure 1 The left, right and Fig. 20 The left and right sides in the figure can be opposite to each other, but for the sake of convenience, Fig. 20 The left and right sides shown are used as references for explanation.

[0528] In addition, the pusher 2310 described below is Fig. 20 The pusher 2310 of the ejector 2300 shown arranged on the left side with reference to the second direction Y is described as an example.

[0529] The ejector 2300 may be provided with a first ejector 2300 corresponding to the first storage chamber 1200 and a second ejector 2300' corresponding to the second storage chamber 1200'. The first ejector 2300 and the second ejector 2300' may be respectively provided with mirror-symmetrical shapes in the second direction Y and may be driven in the second direction Y in a mirror-symmetrical manner.

[0530] Considering that the first ejector 2300 and the second ejector 2300 ′ are driven by the same mechanism, the ejector 2300 will be described below with reference to the first ejector 2300 .

[0531] The pusher 2310 can move linearly from the outside of the storage chamber 1200 to the inside of the storage chamber 1200, thereby pressurizing a solid detergent arranged at the bottom of a plurality of solid detergents in the third direction Z in the direction of linear movement, so that the solid detergent moves to the outside of the storage chamber 1200.

[0532] The pusher 2310 may be disposed outside the storage chamber 1200 on the opposite side of the storage chamber discharge port 1210 in the second direction Y. The pusher 2310 may be disposed to linearly move from the opposite side of the storage chamber discharge port 1210 to the storage chamber discharge port 1210 in the second direction Y relative to the storage chamber 1200.

[0533] The pusher 2310 moves in a direction from the left side to the right side, and can move from the left side of the storage chamber 1200 to the inside of the storage chamber 1200 and move the solid detergent to the right side.

[0534] The pusher 2310 may include a pressurizing portion 2312 a disposed at a side end of the pusher 2310 and disposed toward the solid detergent when linearly moving. As an example, the pressurizing portion 2312 a may be disposed at a right side end of the pusher 2310 .

[0535] The pressurizing portion 2312a can be configured to move to the interior of the storage chamber 1200 according to the parallel movement of the pusher 2310, and can pressurize a solid detergent arranged at the bottom end of a plurality of solid detergents stacked along a third direction Z, so that the solid detergent moves toward the discharge port 1210.

[0536] The ejector 2300 may include a driving motor 2320 and a transmission member 2330 that transmits the rotational force generated by the driving motor 2320 to the pusher 2310 .

[0537] The pusher 2310 may be configured to move in parallel in the second direction Y, and the rotation shaft 2321 of the driving motor 2320 may be configured to be arranged on a dimension formed in the second direction Y.

[0538] As an example, the transmission component 2330 may be configured in a gear shape. As an example, the transmission component 2330 may include a plurality of gears.

[0539] As an example, the transmission member 2330 may include a worm gear to transmit the rotational force of the driving motor 2320 in the second direction Y. As an example, the transmission member 2330 may include a bevel gear.

[0540] The pusher 2310 may include a rack 2315 configured to be connectable with the transmission member 2330 and configured to convert the rotational force received from the transmission member 2330 into a linear movement. The rack 2315 may be configured to mesh with the transmission member 2300 .

[0541] like Fig. 20 As shown, before the ejector 2300 discharges the solid detergent from the storage chamber 1200, the pusher 2310 may be arranged on the left side of the storage chamber 1200. As an example, the pusher 2310 may be arranged outside the storage chamber 1200 in the second direction Y.

[0542] Then, if Fig.21 As shown, the control unit can control the drive motor 2320 in such a way that the drive motor 2320 rotates in one direction. When the drive motor 2320 is driven and transmits the rotational force to the pusher 2310 through the transmission component 2330, the pusher 2310 can move from the left side to the right side, and can pressurize the solid detergent located at the bottom of the multiple solid detergents as it moves toward the right side according to the moving direction.

[0543] As an example, the pusher 2310 may be configured to move the pressurizing portion 2312a from left to right in contact with the solid detergent, and may be configured to discharge the solid detergent to the outside of the storage chamber 1200 through the storage chamber discharge port 1210 .

[0544] Then, if Fig. 22 As shown, when the solid detergent is placed in the placement portion 1400, the control portion can control the drive motor 2320 in such a manner that the drive motor 2320 rotates in the opposite direction. By rotating the drive motor 2320 in the opposite direction, the pusher 2310 can move from the right side to the left side, thereby allowing the pusher 2310 to move back to the outside of the storage chamber 1200.

[0545] When the pusher 2310 is located inside the storage chamber 1200, the solid detergent located at the bottom among the multiple solid detergents remaining inside the storage chamber 1200 is temporarily supported by the support surface 2316 of the pusher 2310. When the pusher 2310 is detached from the outside of the storage chamber 1200, it can move downward along the direction of gravity so that the solid detergent located at the bottom among the multiple solid detergents is supported by the lower surface 1222 of the storage chamber 1200.

[0546] As an example, the driving motor 2320 may be configured to be driven only when the pusher 2310 moves from the left side to the right side to pressurize the solid detergent. At this time, when the driving of the driving motor 2320 ends, the pusher 2310 may be moved from the right side to the left side again by the elastic force of the elastic member connected to the end 2317 arranged on the opposite side of the pressurizing part 2312a and one side of the housing 1100 to move to the outside of the storage chamber 1200.

[0547] Hereinafter, the ejector 3300 and the storage chamber 3200 according to an example will be described in detail.

[0548] Fig.23 1 is a diagram showing a state where a part of the automatic detergent feeding device of a dishwasher according to an embodiment is removed. Fig.24 It is shown Fig.23 A diagram of a state in which the solid detergent loaded in the first storage chamber is discharged from the first storage chamber, Fig.25 It is shown Fig.24 A diagram showing a state in which a solid detergent is placed in a placement portion.

[0549] The ejector 3300 may be disposed at an upper portion of the storage chamber 3200 in the third direction Z to discharge an uppermost solid detergent disposed in the third direction Z from the storage chamber 3200 among a plurality of solid detergents stacked in the third direction Z.

[0550] When automatic detergent feeding device 1000 is arranged at first position 1000A, ejector 3300 may discharge solid detergents located closest to the upper side of storage chamber 3200 among the plurality of solid detergents to the outside of storage chamber 3200 .

[0551] As an example, the ejector 3300 may be configured to pressurize a solid detergent located closest to the upper surface of the storage chamber 3200 among the plurality of solid detergents.

[0552] The storage chamber 3200 may include a storage chamber discharge port 3210 configured to allow one solid detergent to be discharged to the outside of the storage chamber 3200 by the pusher 3300 .

[0553] The storage chamber discharge port 3210 may be disposed at an upper portion of the storage chamber 3200 to discharge an uppermost solid detergent disposed in the third direction Z among a plurality of solid detergents stacked in the third direction Z to the outside of the storage chamber 3200 .

[0554] The storage chamber discharge port 3210 and the ejector 3300 are all disposed at the upper portion of the storage chamber 3200 so that the uppermost solid detergent among the plurality of solid detergents stacked in the third direction Z can be discharged to the outside of the storage chamber 3200 .

[0555] The storage chamber 3200 can be configured to stack multiple solid detergents along a third direction Z, so that when the topmost solid detergent among the multiple solid detergents is discharged to the outside of the storage chamber 3200, the multiple solid detergents can move upward based on the stacking direction by means of the bracket 3500 described later.

[0556] As the plurality of solid detergents all move upward inside the storage chamber 3200, the solid detergents arranged immediately below the solid detergents discharged to the outside of the storage chamber 3200 can move most adjacent to the upper surface of the storage chamber 3200, so as to be arranged in the space where the discharged solid detergents were originally located. The solid detergents can be arranged to be discharged to the outside of the storage chamber 3200 by the ejector 3300 in the next washing stroke of the dishwasher 1.

[0557] That is, when the automatic detergent dispensing device 1000 is arranged in the first position 1000A, as the storage chamber 3200 can be configured to stack a plurality of solid detergents along a third direction Z, and the ejector 3300 can be arranged at the upper portion of the storage chamber 1200, a plurality of solid detergents can be discharged to the outside of the storage chamber 3200 starting from the top in the third direction Z in the order of stacking.

[0558] The ejector 3300 may include a pressurizing member 3310 that pressurizes an uppermost solid detergent arranged in the third direction Z among a plurality of solid detergents stacked in the third direction Z and moves it to the outside of the storage chamber 3200 .

[0559] As an example, the pressurizing member 3310 may include a cam member that pressurizes the solid detergent by rotating. As an example, the pressurizing member 3310 may include Fig. 20 However, the following description will be made by taking the pressurizing member 3310 as an example that the pressurizing member 3310 is the cam member 3310. The pressurizing member 3310 will be referred to as the cam member 3310 below.

[0560] The cam member 3310 may include a pressurizing portion 3312 a provided to protrude from an edge of the cam member 3310 and pressurize the solid detergent while being rotated by the rotation of the cam member 3310 .

[0561] The pressurizing portion 3312a may be configured to rotate and move toward the inside of the storage chamber 3200 as the cam member 3310 rotates, and to move the solid detergent toward the discharge port 3210 by pressurizing one solid detergent disposed at the uppermost end among a plurality of solid detergents stacked in the third direction Z. The cam member 3310 may pressurize the solid detergent in the rotation direction of the cam member 3310 to move the solid detergent.

[0562] For the sake of convenience, the rotation direction of the cam member 3310 and the left and right sides are described below. Fig.23 The illustrated state is used as a reference for explanation. Fig.23 The right side of can be Figure 1 The direction corresponding to the left side of Fig.23 The left side of the Figure 1 The direction corresponding to the right side of , in the second direction Y, Figure 1 The left and right sides can be Fig.23 The left and right sides are opposite to each other, but for the sake of convenience, Fig.23 The left and right sides shown are used as references for explanation.

[0563] The ejector 3300 may be provided with a first ejector 3300 corresponding to the first storage chamber 3200 and a second ejector 3300' corresponding to the second storage chamber 3200'. The first ejector 3300 and the second ejector 3300' may be respectively provided in a mirror-symmetrical shape in the second direction Y and may be driven in a mirror-symmetrical manner in the second direction Y.

[0564] Considering that the first ejector 3300 and the second ejector 3300' are driven by the same mechanism, the first ejector 3300 will be described below by taking the ejector 3300 as a representative. Fig.23 The second direction Y shown is used as a reference, and the cam member 3310 of the ejector 3300 arranged on the left side is described as an example.

[0565] When the cam member 3310 rotates counterclockwise, the cam member 3310 disposed at the lower portion of the storage chamber 3200 may move the solid detergent closest to the upper surface of the storage chamber 3200 to the right side of the storage chamber 1200 while rotating counterclockwise.

[0566] The ejector 3300 may include a transmission part 3330 that transmits the rotational force generated at the driving motor 3320 to the pressurizing part 3310 .

[0567] The transmission component 3330 may include a plurality of gears. Since the rotation axis 3313 of the cam component 3310 is arranged to extend along the first direction X, and the rotation axis of the drive motor 3320 is arranged to extend in a direction orthogonal to the first direction X, the transmission component 3330 may include a worm gear in a manner of vertically converting the transmission direction of the driving force. As an example, the transmission component 3330 may include a bevel gear.

[0568] The automatic detergent dispensing device 1000 may include: a holder 3500, which is configured to keep a plurality of solid detergents in a stacked state inside the storage chamber 3200 when the automatic detergent dispensing device 1000 is arranged in the first position 1000A and the second position 1000B, or when the automatic detergent dispensing device 1000 is moved between the first position 1000A and the second position 1000B.

[0569] As an example, the support 3500 may be provided to be movable toward the plurality of solid detergents in the direction in which the plurality of solid detergents are stacked inside the storage chamber 3200 .

[0570] As an example, the bracket 3500 may be moved in a direction in which the long sides of the storage chamber 3200 extend by guides formed on both side surfaces of the storage chamber 3200 .

[0571] The support 3500 may be provided to be arranged at a lower side of a plurality of solid detergents inside the storage chamber 3200 when the automatic detergent injection device 1000 is arranged at the first position 1000A.

[0572] The bracket 3500 may be provided to be movable from the lower portion to the upper side of the storage chamber 3200 when the automatic detergent feeding device 1000 is arranged at the first position 1000A.

[0573] The bracket 3500 may include an elastic portion 3590 (see FIG. 35A ) connecting the lower surface of the storage chamber 3200 and the bracket. Fig.25 As an example, the elastic part 3590 may be formed of an elastic member. As an example, the elastic part 3590 may be provided as a hydraulic cylinder or the like.

[0574] The elastic portion 3590 may be configured to bias the bracket 3500 upward when the automatic detergent dispenser 1000 is disposed at the first position 1000A.

[0575] Thus, the bracket 3500 may be configured to move upward inside the storage chamber 3200 in the opposite direction of gravity when the automatic detergent dispenser 1000 is arranged at the first position 1000A.

[0576] When the automatic detergent dispensing device 1000 is arranged in the first position 1000A, the stacking direction of the multiple solid detergents can correspond to the third direction Z, and the bracket 3500 can be configured to move upward based on the third direction Z by means of the elastic portion 3290. The bracket 3500 presses the bottommost solid detergent among the multiple solid detergents located in the third direction Z upward, thereby all the multiple solid detergents are pressurized upward, thereby maintaining the stacking arrangement of the multiple solid detergents.

[0577] The bracket 3500 is configured to bias multiple solid detergents in one direction, so even if the automatic detergent dispensing device 1000 is arranged at a position other than the first position 1000A, the bracket 3500 is configured to continuously bias multiple solid detergents in one direction, thereby maintaining the stacked arrangement of multiple solid detergents.

[0578] like Fig.23 and Fig.24 As shown, the control device 1900 may control the ejector 3300 in such a manner that one of the plurality of solid detergents stacked in the storage chamber 3200 moves to the seating portion 1400 .

[0579] As an example, the control device 1900 may control the ejector 3300 in such a manner that the driving motor 3320 is driven to rotate the cam member 3310 in a counterclockwise direction.

[0580] The control device 1900 may control the position of the cam member 3310 so that the cam region 3310A1 of the cam member 3310 is arranged at the lower end in the third direction Z before the cam member 3310 rotates to move the pressurizing portion 3312 a into the storage chamber 3200 .

[0581] Thus, the topmost solid detergent in the third direction Z among the multiple solid detergents loaded into the storage chamber 3200 can be stably located inside the storage chamber 3200, so that the pressurizing portion 3312a can stably move the solid detergent in the second direction Y by the rotation of the cam part 3310.

[0582] As an example, this is because, when a portion of the cam member 3310 moves to the interior of the storage chamber 3200 through the through portion of the storage chamber 3200, the topmost solid detergent in the third direction Z among the plurality of solid detergents loaded into the storage chamber 3200 cannot be arranged horizontally inside the storage chamber 3200. Thus, when the solid detergent moves in the second direction Y, it may not move in the second direction Y due to the center of gravity and may move in other directions by rotation, etc., thereby causing the solid detergent to be unable to move toward the storage chamber discharge port 3210 and unable to be discharged to the outside of the storage chamber 3200.

[0583] The pressurizing portion 3312a can be linked and moved to the inside of the storage chamber 3200 by the rotation of the cam member 3310, thereby the uppermost solid detergent located in the third direction Z can be moved to the right with reference to the second direction Y by the pressurizing portion 3312a.

[0584] The solid detergent may be pressurized by the pressurizing part 3312a to move toward the storage chamber discharge port 3210, and may be discharged to the outside of the storage chamber 3200 through the storage chamber discharge port 3210 as the middle door 3250 closing the storage chamber discharge port 3210 is opened.

[0585] Then, if Fig.25 As shown, the solid detergent may be arranged on the seating portion 1400 , and in detail, may be located on the seating portion 1410 .

[0586] The seating section sensor 1440 may sense the position of the solid detergent to determine whether the solid detergent is located in the seating section inner space 1401. In detail, the seating section sensor 1440 may be disposed on the seating section 1410 in the third direction Z and sense whether the solid detergent is located on the seating section 1410.

[0587] Then, the control device 1900 can control the ejector 3300 to rotate the cam member 3310 further counterclockwise, thereby causing the pressurizing portion 3312a to rotate counterclockwise and detach from the storage chamber 3200, and causing the plurality of solid detergents to move upward based on the third direction Z via the bracket 3500.

[0588] As the pressurizing portion 3312a is disengaged from the outside of the storage chamber 3200, the cam area 3310A1 can be moved back to the inside of the storage chamber 3200, and the plurality of solid detergents can be moved upward based on the third direction Z under the pressurization of the bracket 3500 and the guidance of the cam area 3310A1.

[0589] Hereinafter, a cross-sectional area of ​​the storage chamber 1200 according to an example will be described in detail.

[0590] Fig.26 The figure shows a state where a part of the structure of the automatic detergent feeding device of the dishwasher according to one embodiment is removed.

[0591] As an example, Fig.26 As shown in FIG. 1 , a lateral length L1 of the first storage chamber 1200 and a lateral length L5 of the second storage chamber 1200 ′ may be formed to be different from each other.

[0592] As an example, the lateral length L1 of the first storage chamber 1200 may be set to have a predetermined length so that the solid detergent D described above can be stored in the storage chamber 1200. The lateral length L5 of the second storage chamber 1200' may be set to a length smaller than the lateral length L1 of the first storage chamber 1200.

[0593] As an example, the lateral length L5 of the second storage chamber 1200 ′ may be set to be longer than the lateral length L1 of the first storage chamber 1200 .

[0594] The width L4 of the seating portion 1400 in the second direction Y may be set to a length substantially similar to the width L1 of the first storage chamber 1200. This is because when the width L4 of the seating portion 1400 is formed to be much smaller than the width L5 of the second storage chamber 1200', when the solid detergent is discharged from the first storage chamber 1200 to the seating portion 1400, it may be stuck in the seating portion inner space 1401 and cannot be seated in the seating portion 1410.

[0595] On the contrary, when the width L4 of the seating portion 1400 in the second direction Y is formed to be much larger than the width L1 of the first storage chamber 1200 or the width L5 of the second storage chamber 1200', the volume of the seating portion 1400 in the second direction Y increases more than necessary, and the problem of the volume of the automatic detergent dispensing device 1000 in the second direction Y increasing more than necessary may occur.

[0596] Therefore, preferably, as described above, the width L4 of the seating portion 1400 is formed to have a length similar to the width L1 in the second direction Y of the first storage chamber 1200 having the cross-sectional area S in consideration of the size of the solid detergent.

[0597] Considering the capacity of the barrel 12 of the conventional dishwasher 1, the solid detergent D has an appropriate volume for washing. If the solid detergent D is defined as a conventional solid detergent D having a predetermined transverse length d1 according to the appropriate volume, the volume of the small solid detergent D' stored in the second storage chamber 1200' is smaller than the volume of the conventional solid detergent D, and can be defined as a small solid detergent D' having a transverse length d1' smaller than the transverse length d1 of the solid detergent D. Alternatively, the small solid detergent D' can be a solid detergent D' in a state where a portion of the conventional solid detergent D is cut in the direction of the transverse length d1.

[0598] In the case where the user wants to wash only a small amount of dishes, generally, the washing of the small amount of dishes can be performed using a smaller amount than the conventional solid detergent D formed in consideration of the capacity of the tub 12 .

[0599] Independently of the regular solid detergent D stored in the first storage chamber 1200, the second storage chamber 1200' can store small solid detergent D' having a different volume from the solid detergent D, so that the user can selectively wash with the regular solid detergent D or with the small solid detergent D' as needed.

[0600] The user may input information about the washing mode of the dishwasher 1 through an input portion of the dishwasher 1 or a mobile device, etc., so that the dishwasher 1 selectively performs one of the normal washing mode and the small amount washing mode.

[0601] The control device 1900 may control the automatic detergent injection device 1000 to drive the first ejector 1300 or the second ejector 1300 ′ based on the user input acquired from the main control device.

[0602] When the user selects the normal washing mode, the control device 1900 may control the automatic detergent injection device 1000 to drive the first ejector 1300 .

[0603] When the user selects the small amount washing mode, the control device 1900 may control the automatic detergent injection device 1000 to drive the second ejector 1300 ′.

[0604] Hereinafter, the adjusting member 1270 for adjusting the cross-sectional area of ​​the storage chamber 1200 according to an example will be described in detail.

[0605] Fig. 27 1 is a diagram showing a state where a part of the automatic detergent feeding device of a dishwasher according to an embodiment is removed. Fig.28 It is shown Fig. 27 A diagram showing a state in which the adjustment component of the second storage chamber moves.

[0606] As an example, Fig. 27 and Fig.28 As shown, the storage chamber 1200 may include an adjustment member 1270 configured to adjust a width of the interior of the storage chamber 1200 .

[0607] Considering the capacity of the barrel 12 of the conventional dishwasher 1, the above-mentioned solid detergent D has an appropriate volume for washing. When the above-mentioned solid detergent D is defined as a conventional solid detergent D having a predetermined lateral length d1 according to the appropriate volume, for a part of the solid detergent D", its capacity is formed to be smaller than the capacity of the conventional solid detergent D, so that the width d1" of the solid detergent D" can be formed to be smaller than the width d1 of the conventional solid detergent D.

[0608] As an example, when a portion of solid detergent D" is stacked in a storage chamber 1200 having a width formed corresponding to the width d1 of a conventional solid detergent D, inside the storage chamber 1200, movement in the second direction Y occurs between the solid detergent D" due to the gap between the right side surface 1230 or the left side surface 1240 of the storage chamber 1200 and the portion of the solid detergent D", whereby a portion of the solid detergent D" may detach from the stacked state of the solid detergent D". When the ejector 1300 is driven in a state in which a portion of the solid detergent D" is detached, a plurality of solid detergents D" cannot move in the third direction Z with the ejector 1300, so that a portion of the solid detergent D" may be stuck inside the storage chamber 1200 and cannot be discharged to the outside of the storage chamber 1200.

[0609] As an example, the storage chamber 1200 may include an adjustment member 1270 capable of adjusting the width of the storage chamber 1200 in the second direction Y, and the adjustment member 1270 may be moved in the second direction Y to adjust the width of the storage chamber 1200 .

[0610] Even if the width d1” of the partial solid detergent D” is formed to be smaller than the width d1 of the conventional solid detergent D, the adjusting part 1270 can adjust the width L6 of the storage chamber 1200 to correspond to the width d1” of the partial solid detergent D”, so that the solid detergent D” can maintain a stacked state inside the storage chamber 1200.

[0611] The adjusting component 1270 may include: a supporting wall 1271 supporting a plurality of solid detergents; and a moving portion 1272 configured to be connected to the supporting wall 1271 in the second direction Y so that the supporting wall 1271 moves in the second direction Y and the position of the supporting wall 1271 moves in the second direction Y.

[0612] The adjustment member 1270 may be disposed on the right side surface 1230 or the left side surface 1240 of the storage chamber 1200 .

[0613] The width L1 of the storage chamber 1200 when the support wall 1271 is disposed closest to the right side surface 1230 or the left side surface 1240 may be set to a length substantially corresponding to the width d1 of the general solid detergent D.

[0614] The user can adjust the width of the storage chamber 1200 by pressurizing the support wall 1271 in the second direction Y. As an example, the support wall 1271 can be moved in the second direction Y from a position where the support wall 1271 is adjacent to the right side surface 1230 or the left side surface 1240 so that the length of the width d1" of the portion of solid detergent D" corresponds to the width L6 of the storage chamber 1200.

[0615] As an example, the moving portion 1272 may be configured to extend or contract in the second direction Y to allow the support wall 1271 to move in the second direction Y inside the storage chamber 1200 .

[0616] As an example, the moving portion 1272 may be configured to be movable between the outside and the inside of the storage chamber 1200 in the second direction Y, thereby configuring the support wall 1271 to move in the second direction Y inside the storage chamber 1200 .

[0617] As an example, the user can open the storage chamber 1200 by opening the storage chamber cover 1140, and can move the adjustment member 1270 in the second direction Y to set the user's desired width of the storage chamber 1200. The user can selectively adjust the width of the storage chamber 1200 by holding the support wall 1271 and moving the support wall 1271 in the second direction Y to form the user's desired width of the storage chamber 1200. As the user pressurizes the support wall 1271, the moving part 1272 can extend or contract in the second direction Y.

[0618] As an example, the adjustment member 1270 may be driven by the adjustment member driving device under the control of the control device 1900. The user may input information about the width of the storage chamber 1200 to the dishwasher 1 through the input unit of the dishwasher 1 or a mobile device, etc. The control device 1900 may move the moving portion 1272 based on the user input obtained from the main control device to move the adjustment member 1270 a predetermined distance in the second direction Y, or the control device 1900 may control the adjustment member 1270 to extend or retract the moving portion 1272.

[0619] The bracket 1500 may be disposed to move between the support wall 1271 and a surface 1230 , 1240 of the right side surface 1230 or the left side surface 1240 where the adjustment member 1270 is not arranged.

[0620] As an example, a guide rail 1290 for guiding the movement of the bracket 1500 may be arranged on the support wall 1271. The bracket 1500 may be configured to move in parallel in the third direction Z guided by the guide rail 1290 arranged on the support wall 1271 and the guide rail 1290 arranged on the surface 1230, 1240 of the right side surface 1230 or the left side surface 1240 where the adjustment member 1270 is not arranged.

[0621] The bracket 1500 may be configured to have a shape that contracts in the second direction Y when the support wall 1271 moves in a direction away from the right side surface 1230 or the left side surface 1240 .

[0622] The bracket 1500 may be configured to be in a shape that contracts or extends in the second direction Y. As an example, the bracket 1500 may be configured to be in a telescope shape so that it can be folded and contracted when the support wall 1271 moves toward the center direction of the storage chamber 1200, and can be unfolded and extended when the support wall 1271 moves in a direction opposite to the center direction of the storage chamber 1200.

[0623] The regulating member 1270 may include a first regulating member 1270 disposed inside the first storage chamber 1200 and a second regulating member 1270 ′ disposed inside the second storage chamber 1200 ′.

[0624] As an example, the user may adjust the widths of the first storage chamber 1200 and the second storage chamber 1200 ′ by moving the first adjustment member 1270 and the second adjustment member 1270 ′, respectively.

[0625] As an example, the user may maintain the width L1 of the first storage chamber 1200 and the second storage chamber 1200 ′ by not moving both the first adjustment member 1270 and the second adjustment member 1270 ′.

[0626] As an example, the user may adjust the width of the first storage chamber 1200 or the second storage chamber 1200 ′ by moving only one of the first adjustment member 1270 and the second adjustment member 1270 ′.

[0627] As an example, the first regulating member 1270 may be disposed on the left side surface 1240 of the first storage chamber 1200. The second regulating member 1270' may be disposed on the right side surface 1230' of the second storage chamber 1200'.

[0628] As an example, the second regulating member 1270 ′ may be disposed on the left side surface 1240 ′ of the second storage chamber 1200 ′. The first regulating member 1270 may be disposed on the right side surface 1230 of the first storage chamber 1200 .

[0629] As an example, the first regulating member 1270 and the second regulating member 1270 ′ may be disposed on the left side surface 1240 of the first storage chamber 1200 and the left side surface 1240 ′ of the second storage chamber 1200 ′, respectively.

[0630] As an example, the first regulating member 1270 and the second regulating member 1270 ′ may be disposed on the right side surface 1230 of the first storage chamber 1200 and the right side surface 1230 ′ of the second storage chamber 1200 ′, respectively.

[0631] As an example, the regulating member 1270 may be provided in only one storage chamber 1200 , 1200 ′ of the first storage chamber 1200 and the second storage chamber 1200 ′.

[0632] As an example, Fig.28 As shown, the adjusting component 1270 of the first storage chamber 1200 can be arranged adjacent to the left surface 1240, so that the width L1 of the first storage chamber 1200 corresponds to the width d1 of the conventional solid detergent D, and the adjusting component 1270' of the second storage chamber 1200' can be set to move from the right side surface 1230' to the second direction Y, so that the width L6 of the second storage chamber 1200' corresponds to the width d1" of the partial solid detergent D".

[0633] At this time, the user may load regular solid detergent D into the first storage chamber 1200 and may load partial solid detergent D" into the second storage chamber 1200'.

[0634] The storage chamber 1200 may include an adjustment component sensing sensor for sensing the positions of the respective support walls 1271, 1271'. It may be configured that the adjustment component sensing sensor senses the positions at which the support wall 1271 inside the first storage chamber 1200 and the support wall 1271' of the second storage chamber 1200' are arranged, and the control device 1900 may identify the types of the solid detergent loaded in the first storage chamber 1200 and the solid detergent loaded in the second storage chamber 1200' according to the sensed values.

[0635] As an example, the adjustment component sensing sensor may measure the distance between the respective support walls 1271, 1271', or may sense the distance between the respective support walls 1271, 1271' by sensing the length of the respective moving parts 1272, 1272' being moved, extended or contracted.

[0636] The user may input information about the washing mode of the dishwasher 1 through an input portion of the dishwasher 1 or a mobile device, etc., so that the dishwasher 1 selectively performs one of the normal washing mode and the small amount washing mode.

[0637] The control device 1900 may control the automatic detergent injection device 1000 to drive the first ejector 1300 or the second ejector 1300 ′ based on the user input acquired from the main control device and the value sensed by the adjustment part sensing sensor.

[0638] As an example, when the user selects the normal washing mode, the control device 1900 may control the automatic detergent injection device 1000 to drive the first ejector 1300. When the user selects the small amount washing mode, the control device 1900 may control the automatic detergent injection device 1000 to drive the second ejector 1300'.

[0639] As described above, as an example, the support 1500 may be configured to be movable toward the plurality of solid detergents in the direction in which the plurality of solid detergents are arranged inside the storage chamber 1200, so that the plurality of solid detergents are kept arranged inside the storage chamber 1200. Thus, regardless of the direction in which the automatic detergent feeding device 1000 is located, the plurality of solid detergents loaded inside the storage chamber 1200 can be kept arranged in the storage chamber by the support 1500, so that when the ejector 1300 is driven, the plurality of solid detergents can be easily discharged from the inside of the storage chamber 1200. This is because when the arrangement of the plurality of solid detergents cannot be maintained, the ejector 1300 cannot easily disengage the solid detergents from the storage chamber 1200.

[0640] As described above, as an example, the bracket 1500 may be arranged so that when the stacking direction of the plurality of solid detergents faces a direction different from the up-down direction due to the opening of the door 20, the bracket 1500 may support one of the plurality of solid detergents that is located closest to the bracket 1500 to maintain the arrangement of the plurality of solid detergents. When the automatic detergent feeding device 1000 is arranged at the first position 1000A, the direction of gravity corresponds to the stacking direction of the plurality of solid detergents, so that the arrangement can be easily maintained, but when the stacking direction of the plurality of solid detergents faces a direction different from the up-down direction, it is difficult to maintain the arrangement of the plurality of solid detergents, and therefore, the bracket 1500 may easily maintain the arrangement of the plurality of solid detergents by supporting one end of the arrangement of the plurality of solid detergents.

[0641] As described above, as an example, the storage chamber discharge port 1210 and the ejector 1300 may be arranged at the lower portion of the storage chamber 1200. Thus, the solid detergent located at the bottom preferentially moves to the outside of the storage chamber 1200, and as the solid detergent located at the bottom in the gravity direction is separated, the plurality of solid detergents may naturally move downward while being arranged by gravity, thereby making it easy to maintain the arrangement of the plurality of solid detergents.

[0642] As described above, as an example, the support 1500 may be configured to be movable from the upper portion of the storage chamber 1200 along the arrangement direction of the plurality of solid detergents. Thus, the support 1500 may be configured to pressurize the plurality of solid detergents in a direction corresponding to the arrangement direction of the plurality of solid detergents by gravity, and the plurality of solid detergents may remain arranged under the pressure of the support 1500, and the solid detergent located at the bottom of the plurality of solid detergents may be pressurized toward the lower surface 1222 of the storage chamber 1200.

[0643] As described above, as an example, the ejector 1300 is configured to discharge a solid detergent to the outside of the storage chamber 1200 in a direction orthogonal to the stacking direction of the plurality of solid detergents. Even if the automatic detergent feeding device 1000 stores a plurality of solid detergents, the capacity of the automatic detergent feeding device 1000 can be set thinner in the first direction X by setting the moving direction of the solid detergent and the stacking direction of the plurality of solid detergents differently, thereby being easily mounted on the door 20.

[0644] As described above, as an example, the storage chamber discharge port 1210 can be arranged at the lower part of the storage chamber so that the solid detergent located at the bottom in the vertical direction among the plurality of solid detergents is discharged. Thus, the plurality of solid detergents can be discharged to the outside of the storage chamber 1200 in order starting from the solid detergent arranged at the bottom in the gravity direction.

[0645] As described above, as an example, the ejector 1300 may be arranged at the lower portion of the storage chamber 1200 to move the lowest solid detergent in the vertical direction. Thus, the ejector 1300 may easily discharge the lowest solid detergent in the vertical direction among the plurality of solid detergents to the outside of the storage chamber 1200 in the assembled position.

[0646] As described above, as an example, the cam member 1310 is configured to rotate in the first rotation direction relative to the storage chamber 1200 so that the solid detergent located at the bottom is discharged to the outside of the storage chamber 1200. Thus, the ejector 1300 can easily discharge the solid detergent to the outside of the storage chamber 1200 by the rotation of the cam member 1310, thereby eliminating the need for movement based on physical connection of additional components, thereby minimizing the volume of the ejector 1300.

[0647] As described above, as an example, the pressurizing unit 1312a can be configured to rotate in a first rotation direction and pressurize a solid detergent in a direction orthogonal to the stacking direction of the plurality of solid detergents. Thus, the ejector 1300 can move the solid detergent in a direction orthogonal to the stacking direction of the solid detergents, thereby minimizing the size of the internal space of the automatic detergent feeding device 1000.

[0648] As described above, as an example, as the cam member 1310 rotates in the first rotation direction, the cam member 1310 guides the plurality of solid detergents to move in parallel along the stacking direction of the plurality of solid detergents inside the storage chamber 1200. This is because, while the cam member 1310 rotates and pressurizes the solid detergents, the pressurizing portion 1312a rotates, and during the rotation of at least a portion of the cam 1310 located inside the storage chamber 1200, the plurality of solid detergents remaining inside the storage chamber 1200 are configured to gradually move to the lower side by the rotation of the cam 1310.

[0649] As described above, as an example, the rack 1500 is provided to be movable in the up-down direction from the upper portion of the storage chamber 1200 in the direction in which the plurality of solid detergents are stacked. Thus, the rack 1500 can fix the plurality of solid detergents in the gravity direction when the door 20 is closed.

[0650] As described above, as an example, the support 1500 may be arranged so that when the direction in which the plurality of solid detergents are stacked faces a direction different from the up-down direction due to the opening of the door 20, the support 1500 may support the uppermost solid detergent among the plurality of solid detergents. Thus, even if the stacking direction of the plurality of solid detergents is a direction different from the gravity direction, the support 1500 may support the stacking of the plurality of solid detergents.

[0651] As described above, as an example, the placement portion 1400 may be arranged at one side of the storage chamber 1200 in a direction perpendicular to the stacking direction of the plurality of solid detergents. Thus, the solid detergents moved in a direction perpendicular to the stacking direction of the plurality of solid detergents by the ejector 1300 may be easily placed in the placement portion 1400.

[0652] As described above, as an example, the cam member is configured to rotate in the direction where the seating portion is arranged. Thus, the solid detergents moved in a direction orthogonal to the stacking direction of the plurality of solid detergents by the ejector 1300 can be easily seated in the seating portion 1400 .

[0653] As described above, as an example, the placement portion opening may be set to be open in the up-down direction.
