[0137] The detergent automatic input device 1000 can be arranged on the inner surface 21 of the door 20. The detergent automatic input device 1000 can be configured to be combined with the inner surface 21 of the door 20.

[0138] The detergent box 90 can be arranged on the inner surface 21 of the door 20. The detergent automatic input device 1000 and the detergent box 90 can be configured to be arranged along the third direction Z as the up-and-down direction when the door 20 closes the tub 12.

[0139] Since the detergent automatic input device 1000 is arranged on the door 20, it can be configured to rotate together with the door 20 by the rotation of the door 20.

[0140] 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 open and close the tub 12 by moving between the first position 20A and the second position 20B.

[0141] Here, 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.

[0142] The automatic detergent dispensing device 1000 may be configured to be linked with the door 20 so as to be able to move between a first position 1000A corresponding to the first position 20A of the door 20 and a second position 1000B corresponding to the second position 20B of the door 20 .

[0143] When the door 20 closes the tub 12 , the automatic detergent feeding device 1000 may be arranged at the first position 1000A, and when the door 20 opens the tub 12 , the automatic detergent feeding device 1000 may be arranged at the second position 1000B.

[0144] like Figure 3 As shown, when the automatic detergent feeding device 1000 is arranged at the second position 1000B, the user can load a plurality of solid detergents into the automatic detergent feeding device 1000 .

[0145] The user may open the storage chamber cover 1140 of the automatic detergent feeding device 1000 and load a plurality of solid detergents into the storage chamber 1200 .

[0146] In the prior art, whenever the dishwasher performs dishwashing, the user has to load detergent into the automatic detergent injection device or the detergent box each time, which causes inconvenience to the user. However, according to an embodiment, the automatic detergent injection device 1000 of the dishwasher 1 is configured to allow the user to load multiple solid detergents into the automatic detergent injection device 1000 at one time, and when the dishwasher 1 performs a washing cycle, only one of the multiple solid detergents can be injected into the barrel 12 in one washing cycle.

[0147] During the washing process of the dishwasher 1, since a plurality of solid detergents remain in the automatic detergent feeder 1000, water may flow into the automatic detergent feeder 1000 during the washing process, thereby possibly causing a problem that the plurality of solid detergents may be damaged.

[0148] As the detergent automatic input device 1000 moves between the first position 1000A and the second position 1000B, there may be a problem that multiple solid detergents loaded into the detergent automatic input device 1000 are detached from the stored positions.

[0149] Hereinafter, the detergent automatic input device 1000 that can solve the above problems will be described in detail.

[0150] Figure 4 is an exploded perspective view of a detergent automatic input device of a dishwasher according to an embodiment, Figure 5 is an exploded perspective view of the detergent automatic input device of a dishwasher in another direction according to an embodiment, Figure 6 is a perspective view of a state in which a part of the detergent automatic input device of a dishwasher according to an embodiment is removed, Figure 7 is an enlarged perspective view of a part of the detergent automatic input device of a dishwasher according to an embodiment, Figure 8 is a view showing a state in which a part of the detergent automatic input device of a dishwasher according to an embodiment is removed.

[0151] As Figure 4 and Figure 5 shown, the detergent automatic input device 1000 may include a housing 1100.

[0152] The housing 1100 may include a first housing 1110 that forms a storage chamber 1200 to be described later and a second housing 1120 coupled to the first housing 1110.

[0153] The first housing 1110 may be configured to be coupled to the inner surface 21 of the door 20.

[0154] The second housing 1120 may be configured to be coupled to the first housing 1110 in the first direction X when the detergent automatic input device 1000 is disposed at the first position 1000A.

[0155] The second housing 1120 may form the 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 input port 1122 configured to communicate with a placement portion 1400 to be described later and allow solid detergent to be discharged from the detergent automatic input device 1000 and input into the tub 12.

[0156] The housing 1100 may include an intermediate housing 1130 disposed between the first housing 1110 and the second housing 1120 and supporting a pusher 1300 and the like disposed inside the housing 1100.

[0157] As an example, the configuration of the ejector 1300 or the like can be disposed in the first housing 1110 and supported by the intermediate housing 1130. As an example, the configuration of the ejector 1300 or the like can be disposed in the second housing 1120 and supported by the intermediate housing 1130.

[0158] As an example, the intermediate housing 1130 can be integrally formed with the first housing 1110. As an example, the intermediate housing 1130 can be integrally formed with the second housing 1120.

[0159] The housing 1100 can include a storage chamber lid 1140 configured to be disposed on the second housing 1120 and open and close the storage chamber opening 1121.

[0160] The housing 1100 can include a loading port lid 1150 configured to be disposed on the second housing 1120 and open and close the loading port 1122.

[0161] The first housing 1110 can include a control device placement portion 1111 disposed in a direction opposite to the direction in which the first housing 1110 is coupled to the second housing 1120 and for placing the control device 1900 of the automatic detergent input device 1000.

[0162] As an example, the control device placement portion 1111 can be disposed on the outer side of the interior of the housing 1100 formed by the combination of the second housing 1120 and the first housing 1110. As an example, the control device placement portion 1111 can be disposed inside the housing 1100 formed by the combination of the second housing 1120 and the first housing 1110.

[0163] The first housing 1110 can include a control device cover 1112 that covers the control device placement portion 1111 from the outside. Since the control device cover 1112 is disposed outside the internal space of the housing 1100 rather than in the internal space of the housing 1100 generated by the combination of the first housing 1110 and the second housing 1120, when it is necessary to replace the control device 1900, the control device 1900 can be easily replaced without disassembling the first housing 1110 and the second housing 1120.

[0164] The control device 1900 can control the driving of the ejector 1300 and the placement portion 1410 to be described later, and can control the automatic detergent input device 1000 based on the sensed values of various sensors.

[0165] The control device 1900 can be configured to be able to communicate with the main control device of the dishwasher 1. As an example, the control device 1900 and the main control device can constitute the control unit of the dishwasher 1.

[0166] The main control device can obtain user input through the input unit of the dishwasher 1 or a mobile device, etc., and can control the drive of the dishwasher 1 based on this.

[0167] The main control device can send the received information about user input to the control device 1900. The control device 1900 can control the detergent automatic dosing device 1000 based on the information about the input received from the main control device.

[0168] The detergent automatic dosing device 1000 can include: a wire W that electrically connects the control device 1900 and the electrical components configured to drive the detergent automatic dosing device 1000. The wire W can electrically connect the electrical components (such as the drive motor 1320, the placement department drive unit 1470, and various sensors, etc.) configured to drive the detergent automatic dosing device 1000 and the control device 1900 so that one of the multiple solid detergents loaded inside the storage chambers 1200, 1200' is put into the tub 12.

[0169] 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 configured to electrically connect only a part of the components such as various electrical components of the detergent automatic dosing device 1000 and the control device 1900 or the main control device of the dishwasher 1.

[0170] As an example, at least a part of the components such as various electrical components, sensors, the control device 1900, or the main control device of the dishwasher 1 of the detergent automatic dosing device 1000 can be configured to transmit and receive signals to and from each other not through the wire W but through wireless communication.

[0171] The control device 1900 can control the detergent automatic dosing device 1000 based on the values sensed by various sensors of the detergent automatic dosing device 1000. This will be described in detail later.

[0172] As Figures 6 to 8 shown, the detergent automatic dosing device 1000 can include a storage chamber 1200 configured to load multiple solid detergents.

[0173] The storage chamber 1200 can be configured to stack multiple solid detergents along the third direction Z as the up - down direction when the detergent automatic dosing device 1000 is arranged at the first position 1000A. As an example, the storage chamber 1200 can be configured as multiple storage chambers 1200, 1200'. However, for the sake of easy explanation, the description will be based on one storage chamber 1200.

[0174] The storage chamber 1200 can be configured by the space formed by the first housing 1110 and the second housing 1120. When the detergent automatic input device 1000 is arranged at the first position 1000A, the detergent automatic input device 1000 can be configured to have a space with a long side 1201 extending in the third direction Z, so that a plurality of solid detergents are stacked along the third direction Z and loaded.

[0175] As an example, the storage chamber 1200 can be configured by the space formed by the first housing 1110. As an example, the storage chamber 1200 can be configured by the space formed by the second housing 1120.

[0176] When the storage chamber cover 1140 opens the storage chamber opening 1121, the storage chamber 1200 can be opened outward through the storage chamber opening 1121. As Figure 3 shown, when the detergent automatic input device 1000 is arranged at the second position 1000B, the user can open the storage chamber cover 1140 and put a plurality of solid detergents into the storage chamber 1200 to load the plurality of solid detergents into the storage chamber 1200.

[0177] Since the detergent automatic input device 1000 is arranged on the inner surface 21 of the door 20, when the door 20 is opened, the detergent automatic input device 1000 is arranged outside the washing chamber C so that the user can easily input the detergent.

[0178] The storage chamber 1200 can be set to have a volume above a predetermined size to store a plurality of solid detergents. As described above, since the detergent automatic input 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 can decrease. To prevent the volume of the storage chamber 1200 from increasing in the first direction X, the storage chamber 1200 can be set so that when the detergent automatic input device 1000 is located at the first position 1000A, a plurality of solid detergents are stacked in the third direction Z as the up and down direction.

[0179] A plurality of solid detergents are loaded into the storage chamber 1200 in such a way that when the detergent automatic input device 1000 is arranged at the first position 1000A, they are not arranged in the first direction X but only stacked in the third direction Z.

[0180] As the storage chamber 1200 is formed so that a plurality of solid detergents are only stacked in the third direction Z, as described above, the space of the washing chamber C can be maximally ensured in the first direction X, and in the detergent automatic input device 1000, the space of the storage chamber 1200 in the second direction Y can also be ensured.

[0181] As the storage chamber 1200 is formed such that a plurality of solid detergents are stacked only in the third direction Z, the drive structure of the ejector 1300 such as the transmission member 1330 of the detergent automatic feeder 1000 or the electrical structure of the control device 1900 or the like can be arranged in the second direction Y with respect to the storage chamber 1200. Therefore, the volume of the detergent automatic feeder 1000 in the second direction Y can be minimized.

[0182] Accordingly, on the inner surface 21 of the door 20, additional structures other than the detergent automatic feeder 1000 can be arranged outside the detergent automatic feeder 2000 in the second direction Y, thereby increasing the dimensional ratio of the volume of the main body 10 of the dishwasher 1 to the volume of the internal space of the tub 12.

[0183] Not limited thereto, a plurality of solid detergents are loaded into the storage chamber 1200 in such a manner that they are stacked and arranged only in the second direction Y, which is the left - right direction, when the detergent automatic feeder 1000 is arranged at the first position 1000A.

[0184] The detergent automatic feeder 1000 may include an ejector 1300 that moves one solid detergent out of the plurality of solid detergents to the outside of the storage chamber 1200, so that one solid detergent out of the plurality of solid detergents loaded into the storage chamber 1200 is discharged from the storage chamber 1200. As an example, the ejectors 1300 may be provided in a plurality corresponding to the plurality of storage chambers 1200, 1200'. However, for ease of explanation, the description will be based on one ejector 1300.

[0185] The ejector 1300 may be arranged such that when the detergent automatic feeder 1000 is arranged at the first position 1000A, the lowermost one of the plurality of solid detergents stacked in the third direction Z is discharged from the storage chamber 1200.

[0186] The ejector 1300 may be arranged along the extension direction of the long side 1201 on one side 1201a of the long side 1201. When the detergent automatic feeder 1000 is arranged at the first position 1000A, one side 1201a of the long side 1201 may be arranged on the lower side in the third direction Z, and the other side 1201b of the long side 1201 may be arranged on the upper side.

[0187] The ejector 1300 may be arranged in the lower part of the storage chamber 1200 in the third direction Z, so that the lowermost one of the plurality of solid detergents stacked in the third direction Z is discharged from the storage chamber 1200.

[0188] When the detergent automatic feeding device 1000 is arranged at the first position 1000A, the pusher 1300 can discharge the solid detergent closest to the lower surface 1220 of the storage chamber 1200 among the plurality of solid detergents to the outside of the storage chamber 1200.

[0189] As an example, the pusher 1300 can be set to pressurize the solid detergent placed on the lower surface 1220 of the storage chamber 1200 among the plurality of solid detergents. The solid detergent being placed on the lower surface 1220 means that the solid detergent is set to be supported by the lower surface 1220, or the solid detergent is in contact with the lower surface 1220. Thus, this means that the solid detergent is arranged at a position where it can be pressurized by the pusher 1300 and discharged from the storage chamber 1200.

[0190] The storage chamber 1200 can include: a storage chamber discharge port 1210, which is set to discharge one solid detergent to the outside of the storage chamber 1200 by the pusher 1300.

[0191] The storage chamber discharge port 1210 can be arranged at the lower part of the storage chamber 1200 so that the solid detergent arranged at the lowermost part in the third direction Z among the plurality of solid detergents stacked in the third direction Z is discharged to the outside of the storage chamber 1200.

[0192] Both the storage chamber discharge port 1210 and the pusher 1300 are arranged at the lower part of the storage chamber 1200 so that the lowermost solid detergent among the plurality of solid detergents stacked in the third direction Z can be discharged to the outside of the storage chamber 1200.

[0193] The storage chamber 1200 is set so that a plurality of solid detergents are stacked in the third direction Z. Thus, when the lowermost solid detergent among the plurality of solid detergents is discharged to the outside of the storage chamber 1200, the plurality of solid detergents can move downward based on the stacking direction by gravity.

[0194] Since all the plurality of solid detergents move downward, the solid detergent arranged directly above the solid detergent discharged to the outside of the storage chamber 1200 can move adjacent to the lower surface 1220 of the storage chamber 1200 and can be arranged in the space where the discharged solid detergent is located. This solid detergent can be set to be discharged to the outside of the storage chamber 1200 by the pusher 1300 in the next washing cycle of the dishwasher 1.

[0195] That is, when the detergent automatic feeding device 1000 is arranged at the first position 1000A, since the storage chamber 1200 is arranged such that a plurality of solid detergents are stacked in the third direction Z, and the ejector 1300 is arranged at the lower part of the storage chamber 1200, a plurality of solid detergents can be discharged from the bottommost in the stacking order in the third direction Z to the outside of the storage chamber 1200.

[0196] Not limited thereto, the ejector 1300 can be arranged such that one solid detergent arranged at the uppermost end in the third direction Z among a plurality of solid detergents stacked in the third direction Z is discharged from the storage chamber 1200.

[0197] As Figure 7 shown, when the shape of the solid detergent D is such that the lateral length d1 and the longitudinal length d2 are greater than the height h, the solid detergent D can be loaded into the storage chamber 1200 in a manner of being stacked in the height h direction in the storage chamber 1200.

[0198] For the solid detergent D described below, it is assumed that the lateral length d1 is greater than the longitudinal length d2 and the height h.

[0199] As an example, the solid detergent D can be loaded into the storage chamber 1200 in a manner such that the direction formed by the minimum length among the lateral length d1, the longitudinal length d2, and the height h of the solid detergent D corresponds to the stacking direction of a plurality of solid detergents.

[0200] This is to maximize the number of solid detergents D that can be loaded into the storage chamber 1200.

[0201] As an example, when the detergent automatic feeding device 1000 is arranged at the first position 1000A, the solid detergent D can be loaded into the storage chamber 1200 in a direction in which the surface of the solid detergent D formed in the lateral length d1 and longitudinal length d2 directions faces the cross-sectional area S of the storage chamber 1200 formed in the first direction X and the second direction Y.

[0202] As an example, a plurality of solid detergents D can be stacked inside the storage chamber 1200 in the direction of the height h of the solid detergent D.

[0203] Solid detergents can be set to have various sizes according to the composition, function, or manufacturer of the solid detergent, etc., but the volume of the solid detergent can be mainly determined in proportion to the size of the washing chamber volume 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 can also be set to a size within a predetermined range. Thus, the lateral length, longitudinal length, and height of the solid detergent can be similarly designed regardless of its type.

[0204] The solid detergent D described below can be defined as a suitable solid detergent D that can be loaded into the automatic detergent dispensing device 1000 of the dishwasher 1 according to an example. The lateral length d1, longitudinal length d2, and height h of the solid detergent D are defined as approximate values of the lateral length, longitudinal length, and height of various solid detergents that can be loaded into the detergent dispensing device 1000 of the dishwasher 1, and are values that can vary within a predetermined range. As an example, the lateral length d1 and longitudinal length d2 are defined based on the dimensions set along the first direction X and the second direction Y, and the lateral length can also be defined as d2, and the longitudinal length can also be defined as d1.

[0205] When the detergent dispensing device 1000 is arranged at the first position A, the area s in the first direction X and the second direction Y of the storage chamber 1200 (hereinafter referred to as the cross-sectional area of the storage chamber 1200) can be set to dimensions that are easy to load the solid detergent D and can be stacked along the third direction Z.

[0206] The cross-sectional area S of the storage chamber 1200 can be formed by a pair of sides having a lateral 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 detergent dispensing device 1000 is arranged at the first position A. As an example, the lateral length L1 and longitudinal length L2 are defined based on the dimensions set along the first direction X and the second direction Y, and the lateral length can also be defined as L2, and the longitudinal length can also be defined as L1.

[0207] 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.

[0208] When the solid detergent D is loaded into the storage chamber 1200, the side of the solid detergent D having the lateral length d1 can be arranged to correspond to the side of the storage chamber 1200 having the lateral length L1 of the cross-sectional area S, and the other side of the solid detergent D having the longitudinal length d2 can be arranged to correspond to the side of the storage chamber 1200 having the longitudinal length L2 of the cross-sectional area S.

[0209] As described above, since the longitudinal length d2 of the solid detergent D is formed to be less than the lateral length d1, the lateral length L1 of the cross-sectional area S can be formed to be greater than the longitudinal length L2. In addition, since the lateral length d1 of the solid detergent is formed to be greater than the length of the height h of the solid detergent D, the longitudinal length L2 of the cross-sectional area S can also be formed to be greater than the length of the height h of the solid detergent D.

[0210] The transverse length L1 of the cross-sectional area S can be set to be longer than the transverse length d1 of the solid detergent D by a transverse length that is about 10% to 30% of the transverse length d1 of the solid detergent D with respect to the transverse length d1 of the solid detergent D.

[0211] The longitudinal length L2 of the cross-sectional area S can be set to be longer than the longitudinal length d2 of the solid detergent D by a length that is about 10% to 30% of the longitudinal length d2 of the solid detergent D with respect to the longitudinal length d2 of the solid detergent D.

[0212] The cross-sectional area S of the storage chamber 1200 can be formed to have the above-mentioned values such that when the solid detergent arranged at the lowermost position in the third direction is moved to the outside of the storage chamber 1200 by the pusher 1300, a plurality of solid detergents can move stably downward inside the storage chamber 1200 while maintaining a stacked arrangement.

[0213] When the lengths by which the transverse length L1 and the longitudinal length L2 of the cross-sectional area S are longer than the transverse length d1 and the longitudinal length d2 of the solid detergent D are formed to be less than about 10% of the transverse length d1 and the longitudinal length d2 of the solid detergent D, a plurality of solid detergents are in a state of being stuck inside the storage chamber 1200 while moving downward inside the storage chamber 1200, such that the solid detergents cannot move stably downward.

[0214] As an example, the solid detergent arranged at the lowermost position in the third direction Z among the stacked plurality of solid detergents cannot be placed on the lower surface 1220 of the storage chamber 1200 and is in a state of being stuck inside the storage chamber 1200 when moving downward. Thus, even when the pusher 1300 is driven, the later-described pressing portion 1312a cannot easily press the solid detergent arranged at the lowermost position in the third direction Z, so that the solid detergent cannot be discharged to the outside of the storage chamber 1200.

[0215] When the lengths by which the transverse length L1 and the longitudinal length L2 of the cross-sectional area S are longer than the transverse length d1 and the longitudinal length d2 of the solid detergent D are formed to be greater than about 30% of the transverse length d1 and the longitudinal length d2 of the solid detergent, the stacked arrangement may collapse due to rotational movement or the like while the solid detergents move downward inside the storage chamber 1200.

[0216] As an example, since the cross-sectional area S is formed to be larger than the solid detergent, the solid detergent can rotate or move in an inclined direction with respect to the third direction Z when moving downward, such that the plurality of solid detergents do not move in the third direction but move in the first direction X or the second direction Y simultaneously, and thus cannot maintain a stacked arrangement.

[0217] Therefore, the transverse length L1 and the longitudinal length L2 of the cross-sectional area S can be set to be approximately 10% to 30% longer than the transverse length d1 and the longitudinal length d2 of the solid detergent D in terms of the transverse length d1 and the longitudinal length d2 of the solid detergent D.

[0218] 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 detergent automatic feeding device 1000 can have a predetermined thickness in the direction in which the longitudinal length L2 extends.

[0219] Thus, when the door 20 is arranged at the first position 20A, the detergent automatic feeding device 1000 can protrude from the door 20 toward the inside of the tub 12 in the first direction X, so that the space inside the tub 12 may be partially narrowed.

[0220] In particular, for the lower basket 51 arranged at a height substantially corresponding to the detergent automatic feeding device 1000 in the third direction Z, when the door 20 is arranged at the first position 20A, it may collide with the detergent automatic feeding device 1000 in the first direction X. To prevent this, the detergent automatic feeding device 1000 can be arranged to be spaced apart from the lower basket 51 in the first direction X when arranged at the first position 1000A. As an example, the detergent automatic feeding device 1000 can be arranged to be spaced apart from the middle basket 52 in the first direction X when arranged at the first position 1000A.

[0221] In addition, the door 20 is arranged at the second position 20B, whereby the lower basket 51 can be drawn out from the front surface of the tub 12 in the first direction X. When the lower basket 51 is drawn out from the front, the detergent automatic feeding device 1000 is arranged to have a predetermined thickness in the extending direction of the longitudinal length L2, so the drawing out of the lower basket 51 may be restricted by the thickness of the detergent automatic feeding device 1000.

[0222] The detergent automatic feeding device 1000 can be arranged to be coupled to the inner surface 21 of the door 20. When the detergent automatic feeding device 1000 is coupled to the inner surface 21, it can be coupled to the door 20 in such a way that at least a part of the detergent automatic feeding device 1000 is inserted into the inside of the door 20 in the first direction X.

[0223] Thus, when the detergent automatic feeding device 1000 is arranged at the first position 1000A, a predetermined spacing distance can be easily created between the detergent automatic feeding device 1000 and the lower basket 51 in the first direction X.

[0224] Accordingly, when the detergent automatic feeder 1000 is arranged at the second position 1000B, the protrusion of the detergent automatic feeder 1000 in the third direction Z can be minimized, so that when the lower basket 51 is drawn out in the first direction X, it can be easily drawn out without being restricted by the detergent automatic feeder 1000.

[0225] As an example, the detergent automatic feeder 1000 can be coupled to the inner surface 21 of the door 2 in such a way that when the detergent automatic feeder 1000 is arranged at the second position 1000B, the upper end of the detergent automatic feeder 1000 in the third direction Z is located below the lower end of the lower basket 51 in the third direction Z. Accordingly, when the lower basket 51 slides out of the bucket 12 and is drawn out with the detergent automatic feeder 1000 arranged at the second position 1000B, the lower basket 51 can be drawn out of the bucket 12 without colliding with the detergent automatic feeder 1000.

[0226] The pusher 1300 may include: a pressing member 1310 that presses and moves the lowermost solid detergent among the plurality of solid detergents stacked in the third direction Z to the outside of the storage chamber 1200.

[0227] The pressing member 1310 may include a cam member that presses the solid detergent by rotation. Hereinafter, the pressing member 1310 will be referred to as the cam member 1310.

[0228] The cam member 1310 may include: a pressing portion 1312a that is provided to protrude from the edge of the cam member 1310 and presses the solid detergent while rotating as the cam member 1310 rotates.

[0229] The pressing portion 1312a is provided to be able to rotate as the cam member 1310 rotates, so as to move into the storage chamber 1200, and by pressing the lowermost solid detergent among the plurality of solid detergents stacked in the third direction Z, the solid detergent can be moved to the storage chamber discharge port 1210. The cam member 1310 can press the solid detergent in the rotation direction of the cam member 1310 to move the solid detergent.

[0230] For the sake of convenience of description, the rotation direction of the cam member 1310 and the left and right sides described below will be described based on the Figure 8 shown state. Figure 8 The right side in Figure 1 can be the direction corresponding to the left side in Figure 8 The left side in Figure 1 can be the direction corresponding to the right side inFigure 1 The left and right sides in Figure 8 can be opposite to each other in the second direction Y, but for the sake of convenience of explanation, the left and right sides shown in Figure 8 will be used as a reference for explanation.

[0231] In addition, the cam member 1310 described below will be described by taking as an example the cam member 1310 of the pusher 1300 arranged on the left side with reference to the second direction Y shown in Figure 8 .

[0232] When the rotation direction of the cam member 1310 is the clockwise direction, the pusher 1300 is arranged below the storage chamber 1200 so that the cam member 1310 can move the solid detergent placed 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.

[0233] In order to discharge the solid detergent that has moved to the right side to the outside of the storage chamber 1200, the storage chamber discharge port 1210 can be arranged at the lower part of the right side surface 1230 of the storage chamber 1200.

[0234] The storage chamber 1200 may include: a through hole 1221 formed on the lower surface 1220 of the storage chamber 1200 to allow the pressing part 1312a to move from the outside of the storage chamber 1200 to the inside of the storage chamber 1200.

[0235] The through hole 1221 is arranged to extend not only to the lower surface 1220 of the storage chamber 1200, but also to the lower parts of the right side surface 1230 and the left side surface 1240 of the storage chamber 1200.

[0236] The pressing part 1312a rotates by the rotation of the cam member 1310 and moves into the storage chamber 1200 through the through hole 1221 in the lower part of the left side surface 1240 and the lower surface 1220, and can move out of the storage chamber 1200 through the through hole 1221 in the lower part of the right side surface 1230 and the lower surface 1220 as the cam member 1310 rotates.

[0237] At this time, the pressing part 1312a can be arranged to rotate while pressing the solid detergent placed on the lower surface 1220, so as to move the solid detergent to the right side.

[0238] As Figure 7As shown, the through portion 1221 can be arranged such that at least a part of the lower surface 1220 is open. As at least a part of the lower surface 1220 is open, when the cam member 1310 disposed below the storage chamber 1200 rotates, the pressing portion 1312a can move into the storage chamber 1200 through the through portion 1221.

[0239] The through portion 1221 can be arranged such that not the entire lower surface 1220 is open but only at least a part thereof is open.

[0240] As an example, in the lower surface 1220, it can be arranged such that the area forming the through portion 1221 is smaller than the area of the lower surface 1222 closed in the third direction Z. Hereinafter, the lower surface 1222 closed in the third direction Z is referred to as the support surface 1222. This is because the support surface 1222 supports the lowermost solid detergent in the third direction Z.

[0241] As an example, the through portion 1221 can be arranged to extend in the second direction Y along the center of the lower surface 1220 in the first direction. Thus, the front and rear of the through portion 1221 in the first direction X can be arranged as the support surface 1222.

[0242] This is to stably position the lowermost solid detergent in the third direction Z on the lower surface 1220 when a plurality of solid detergents are stacked. The support surface 1222 supports the lowermost solid detergent in the third direction Z, so that the solid detergent is arranged adjacent to the lower surface 1220. Thus, when the pressing portion 1312a penetrates and moves through the through portion 1221, the solid detergent can be easily pressed.

[0243] In particular, the support surface 1222 can be arranged in front of and behind the through portion 1221 in the first direction X, so that the support surface 1222 can be arranged such that the lowermost solid detergent in the third direction Z is supported on the storage chamber 1200 substantially horizontally in the third direction Z.

[0244] Thus, when the solid detergent moves out of the storage chamber 1200 by the pressing portion 1312a, it can move in the second direction Y in a state substantially parallel to the third direction Z.

[0245] As an example, the support surface 1222 can guide the solid detergent in such a way that the solid detergent moving in the third direction Z moves in a state parallel to the third direction Z. Figure 7Based on a reference, the lower surface us of the solid detergent D is loaded into the storage chamber 1200 in a manner that contacts the support surface 1222 in the third direction Z. 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 can move to the storage chamber discharge port 1210 while remaining substantially horizontal with respect to the third direction Z.

[0246] When the solid detergent moves in the second direction Y in a state inclined with respect to the third direction Z, due to the center of gravity not moving in the second direction Y but rotating or moving in another direction, the solid detergent may not be able to move toward the storage chamber discharge port 1210 and cannot be discharged to the outside of the storage chamber 1200.

[0247] In the cam member 1310, based on the rotation direction of the cam member 1310, the edge of the cam member 1310 may include a plurality of cam regions divided along the rotation direction of the cam member 1310. When defining the cam region having the edge with the shortest radius length from the rotation axis 1313 of the cam member 1310 among the plurality of cam regions as the first cam region 1310A1, the first cam region 1310A1 may be set to be arranged at the upper end of the cam member 1310 when the dishwasher 1 is not driven to the washing stroke.

[0248] The pressurizing portion 1312a may be set to protrude a predetermined height in the radial direction of the cam member 1310 with respect to the first cam region 1310A1.

[0249] The pressurizing portion 1312a may be set to protrude a predetermined height in the radial direction of the cam member 1310 with respect to the first cam region 1310A1 so that the pressure for moving the solid detergent D to the storage chamber discharge port 1210 can be transmitted to the solid detergent D.

[0250] The pressurizing portion 1312a may be set to protrude a predetermined height in the radial direction of the cam member 1310 with respect to the first cam region 1310A1 so that when the cam member 1310 rotates, only the solid detergent D arranged at the lowermost in the third direction Z is pressurized, and the solid detergent D above the lowermost solid detergent D is not pressurized.

[0251] As an example, the pressurizing portion 1312a may be set to protrude 15 mm in the radial direction of the cam member 1310 with respect to the first cam region 1310A1.

[0252] The first cam region 1310A1 of the cam member 1310 can be set to be disposed 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 lowermost solid detergent among the plurality of solid detergents, when arranged on the lower surface 1220 of the storage chamber 1200, will not be pressurized upward on one side by the cam member 1310 with respect to the third direction Z, and will be located in the storage chamber 1200 in a state substantially horizontal with respect to the third direction Z.

[0253] Based on Figure 8 the second direction Y shown, the cam member 1310' of the ejector 1300' arranged on the right side is set to be rotatable counterclockwise based on the Figure 8 direction shown. Thus, the solid detergent loaded into the storage chamber 1200' arranged on the right side can be set to be discharged to the left side of the storage chamber 1200'. This will be described in detail later.

[0254] The rotation axis 1313 of the cam member 1310 can be set to extend in the first direction X when the detergent automatic feeding device 1000 is arranged at the first position 1000A. The cam member 1310 is arranged such that the radial direction of the cam member 1310 is arranged perpendicular to the direction of the first direction X. Thus, when the cam member 1310 is arranged inside the housing 1100, the 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.

[0255] The ejector 1300 can include: a drive motor 1320 that generates a rotational force to drive the cam member 1310. The drive motor 1320 can be arranged such that when the detergent automatic feeding device 1000 is arranged at the first position 1000A, the rotation axis 1321 of the drive motor 1320 extends along a direction substantially orthogonal to the first direction X. Thus, when the drive motor 1320 is arranged inside the housing 1100, the 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.

[0256] The ejector 1300 can include: a transmission member 1330 that transmits the rotational force generated by the drive motor 1320 to the pressing member 1310.

[0257] The transmission member 1330 can include a plurality of gears. Since the rotation axis 1313 of the cam member 1310 is arranged to extend in the first direction X and the rotation axis 1321 of the drive motor 1320 is arranged to extend along a direction orthogonal to the first direction X, the transmission member 1330 can include a worm gear to vertically convert the transmission direction of the driving force. As an example, the transmission member 1330 can include bevel gears.

[0258] When the transmission member 1330 includes a worm gear, the situation where the cam member 1310 rotates arbitrarily due to an external force can be prevented.

[0259] As 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 axis 1313 of the cam member 1310 extends, when the transmission member 1330 is arranged inside the housing 1100, the 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.

[0260] The transmission member 1330 can transmit the rotational force generated in the drive motor 1320 to the cam member 1310 by connecting the cam member 1310 and the drive motor 1320. At this time, the transmission member 1330 can be configured such that the cam member 1310 can rotate at an appropriate rotational speed. As an example, the transmission member 1330 can be configured to reduce the rotational speed of the rotation shaft 1321 of the drive motor 1320. The transmission member 1330 can be configured in various ways according to design factors such as the target rotational speed of the cam member 1310 and the rotational speed of the drive motor 1320.

[0261] When the detergent automatic dispensing device 1000 may include: a holder 1500, which is arranged to keep a plurality of solid detergents in a stacked state inside the storage chamber 1200 when the detergent automatic dispensing device 1000 is arranged at the first position 1000A and the second position 1000B, or when moving between the first position 1000A and the second position 1000B.

[0262] The holder 1500 can move in the direction in which the long side 1201 of the storage chamber 1200 extends by means of guides formed on two side surfaces 1230, 1240 of the storage chamber 1200.

[0263] The holder 1500 can be arranged to move toward the plurality of solid detergents in 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.

[0264] The holder 1500 can be arranged to be located above the plurality of solid detergents inside the storage chamber 1200 when the detergent automatic dispensing device 1000 is arranged at the first position 1000A.

[0265] The holding member 1500 can be set to be movable downward from the upper part of the storage chamber 1200 when the detergent automatic dispenser 1000 is disposed at the first position 1000A. The holding member 1500 can be set to move downward inside the storage chamber 1200 by gravity when the detergent automatic dispenser 1000 is disposed at the first position 1000A.

[0266] When the detergent automatic dispenser 1000 is disposed at the first position 1000A, the stacking direction of the plurality of solid detergents corresponds to the third direction Z, and the holding member 1500 can be set to move downward with respect to the third direction Z by gravity, so as to press downward the solid detergent disposed at the uppermost position in the third direction Z among the plurality of solid detergents.

[0267] The holding member 1500 can include a weight member configured to have a weight greater than a predetermined weight so as to move along the third direction Z by gravity. As an example, the weight member can be integrally provided with the holding member 1500. As an example, the weight member can be provided to be coupled with the holding member 1500.

[0268] As an example, the holding member 1500 can be made of a material with a larger weight so as to have a weight greater than a predetermined weight.

[0269] The holding member 1500 can be set to have a weight greater than a predetermined weight, and can be set to press downward the plurality of solid detergents with respect to the third direction Z.

[0270] When the solid detergent located at the lowermost position in the third direction Z among the plurality of solid detergents is discharged to the outside of the storage chamber 1200 by the ejector 1300, the plurality of solid detergents can move downward with respect to the third direction Z as the stacking direction by gravity. The holding member 1500 can press downward the plurality of solid detergents by gravity, and the holding member 1500 can guide the plurality of solid detergents to move downward.

[0271] As an example, when any one of the plurality of solid detergents stacked along the third direction Z is partially detached from the arrangement and thereby a part of the solid detergent is supported on the two side surfaces 1230, 1240 of the storage chamber 1200, so that the downward movement of the plurality of solid detergents is restricted, the holding member 1500 can press downward the plurality of solid detergents to guide the plurality of solid detergents to move downward.

[0272] As described above, the automatic detergent dispenser 1000 can be set such that when the automatic detergent dispenser 1000 is disposed at the first position 1000A, a plurality of solid detergents are stacked in the third direction Z. Thus, the space efficiency of the automatic detergent dispenser 1000 and the dishwasher 1 in the first direction X and the second direction Y can be improved.

[0273] In addition, as the plurality of solid detergents are disposed in the direction of gravity, the automatic detergent dispenser 1000 can be set such that the plurality of solid detergents can be easily discharged in sequence from below in the direction of gravity.

[0274] However, when the door 20 rotates from the first position 20A to the second position 20B or is disposed at the second position 20B to open the tub 12, the stacking direction of the plurality of solid detergents can be arranged in a direction different from the third direction Z.

[0275] At this time, since the stacking direction of the plurality of solid detergents is in a direction different from the direction of gravity, any one of the plurality of solid detergents may be detached from the stacking structure, so that the stacked arrangement of the plurality of solid detergents in the third direction Z may collapse.

[0276] As an example, as described above, the solid detergent D can be loaded into the storage chamber 1200 in a direction in which the surface of the solid detergent D formed along the transverse length d1 and the longitudinal length d2 of the solid detergent D faces the cross-sectional area S of the storage chamber 1200 formed along the first direction X and the second direction Y.

[0277] As an example, the surface of the solid detergent D formed along the transverse length d1 and the longitudinal length d2 can be set to a curved surface shape instead of a conventional flat surface shape. Thus, when a plurality of solid detergents D are stacked, the solid detergents D facing each other in the stacking direction can be set to face their respective curved surfaces. Therefore, when the stacking direction of the plurality of solid detergents is in a direction different from the direction of gravity, the plurality of solid detergents may be detached from the stacked arrangement.

[0278] That is, since it is more difficult to maintain the stacked state when the curved surfaces of the solid detergents D face each other, when the stacking direction corresponds to the direction of gravity, the holding member 1500 can press the plurality of solid detergents D in the stacking direction, and can support the solid detergents D when the stacking direction is different from the direction of gravity to maintain the arrangement of the plurality of solid detergents D.

[0279] When the stacked arrangement of multiple solid detergents collapses, even if the door 20 is again arranged at the first position 20A, the movement of the multiple solid detergents in the direction of gravity may be restricted, and the solid detergent arranged at the lowermost position in the third direction Z among the multiple solid detergents may be abnormally placed on the lower surface 1220 of the storage chamber 1200, resulting in a problem that the solid detergent cannot be discharged to the outside of the storage chamber 1200 by the ejector 1300.

[0280] The meaning that the solid detergent is abnormally placed on the lower surface 1220 means that when the solid detergent is arranged on the lower surface 1220, it cannot be pressurized by the ejector 1300 or even if it is pressurized by the ejector 1300, it will be arranged at a position where it cannot move to the outside of the storage chamber 1200.

[0281] To prevent this situation, the holding member 1500 can be set to prevent the stacked arrangement of the multiple solid detergents from collapsing when the direction of stacking of the multiple solid detergents is oriented in a direction different from the third direction Z due to the movement of the door 20.

[0282] The holding member 1500 can be set to hold the stacked arrangement of the multiple solid detergents when the door 20 is opened at the first position 20A and moves to the second position 20B, or when the door 20 is arranged at the second position 20B.

[0283] The holding member 1500 can be set to support the solid detergent arranged at the uppermost position in the third direction Z among the multiple solid detergents when the direction of stacking of the multiple solid detergents is oriented in a direction different from the third direction Z.

[0284] The holding member 1500 can be set to be fixed at a position adjacent to the solid detergent arranged at the uppermost position in the third direction Z among the multiple solid detergents when the direction of stacking of the multiple solid detergents is oriented in a direction different from the third direction Z.

[0285] When the direction of stacking of the multiple solid detergents is oriented in a direction different from the third direction Z, the movement of the solid detergent arranged at the uppermost position in the third direction Z among the multiple solid detergents may be temporarily blocked by the holding member 1500 to prevent the solid detergent arranged at the uppermost position in the third direction Z among the multiple solid detergents from separating from the stacked arrangement.

[0286] The storage chamber 1200 may include: a guide rail 1290 that guides the movement of the holding member 1500 inside the storage chamber 1200.

[0287] The holding member 1500 can be guided by the guide rail 1290 and translated in the extending length direction of the long side 1201 of the storage chamber 1200.

[0288] The guide rail 1290 can be set such that when the detergent automatic feeding device 1000 is arranged at the first position 1000A, the holding member 1500 moves downward with respect to the third direction Z as a reference.

[0289] As an example, the holding member 1500 may include a guiding protrusion inserted into the guide rail 1290. The guiding protrusion of the holding member 1500 can be inserted into the guide rail 1290 and move along the extending direction of the guide rail 1290.

[0290] The guide rail 1290 can be set to extend in the extending direction of the long side 1201 of the storage chamber 1200. The holding member 1500 can be set to be able to move along the extending direction of the guide rail 1290.

[0291] The guide rail 1290 may include: a locking portion 1293, which is set to restrict the movement of the holding member 1500 when the detergent automatic feeding device 1000 is not located at the first position 1000A.

[0292] When the door 20 moves from the first position 20A to the second position 20B, since the guiding protrusion of the holding member 1500 is restricted from moving by the locking portion 1293, the movement of the holding member 1500 inside the storage chamber 1200 can be restricted.

[0293] In addition, the holding member 1500 can be set to hold the stacked arrangement of a plurality of solid detergents even when the door 20 is arranged at the second position 20B.

[0294] The holding member 1500 can be set to support the solid detergent arranged at the uppermost position in the third direction Z among a plurality of solid detergents when the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z.

[0295] The holding member 1500 can be set to be fixed at a position adjacent to the solid detergent arranged at the uppermost position in the third direction Z among a plurality of solid detergents when the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z.

[0296] Thus, when the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z, the holding member 1500 can be temporarily fixed inside the storage chamber 1200 by the locking portion 1293, and the movement of the solid detergent arranged at the uppermost position in the third direction Z among the plurality of solid detergents can be restricted by the fixed holding member 1500.

[0297] Even when the stacking direction of multiple solid detergents is different from the third direction Z, the stacking arrangement of multiple solid detergents can be held by the holding member 1500. Therefore, even when the detergent automatic dispensing device 1000 is arranged at the first position 1000A such that multiple solid detergents are arranged to be stacked along the third direction Z, the detergent automatic dispensing device 1000 can be arranged to discharge one of the multiple solid detergents to the outside of the storage chamber 1200 and dispense it into the tub 12.

[0298] The detergent automatic dispensing device 1000 may include: a placement portion 1400, which is arranged to place one solid detergent discharged from the storage chamber 1200.

[0299] The placement portion 1400 may be arranged to communicate with the storage chamber discharge port 1210. The placement portion 1400 may include an internal space 1401 of the placement portion that communicates with the storage chamber discharge port 1210.

[0300] One of the multiple solid detergents can be discharged from the storage chamber 1200 through the storage chamber discharge port 1210 and move to the internal space 1401 of the placement portion.

[0301] The placement portion may include a discharge guide 1430 connected to the tub 12. The discharge guide 1430 may be arranged as a space connected to the internal space 1401 of the placement portion.

[0302] As an example, the internal space 1401 of the placement portion and the discharge guide 1430 may be formed as one space, and the space of the internal space 1401 of the placement portion and the discharge guide 1430 may be divided by a placement portion opening 1420 opened and closed by a placement portion part 1410 described later.

[0303] As an example, the lower end of the internal space 1401 of the placement portion in the third direction Z may be formed as the placement portion opening 1420, and the discharge guide 1430 may be a region formed downward along the third direction Z from the placement portion opening 1420.

[0304] The placement portion 1400 may be arranged such that one solid detergent that moves into the internal space 1401 of the placement portion is temporarily placed in the placement portion 1400 and then dispensed into the tub 12.

[0305] The placement portion 1400 may include: a placement portion opening 1420 that connects the internal space 1401 of the placement portion to the discharge guide 1430 connected to the tub 12. The placement portion opening 1420 may be arranged to open toward the third direction Z when the detergent automatic dispensing device 1000 is arranged at the first position 1000A.

[0306] The placement unit 1400 may include a placement section 1410 that opens and closes the placement unit opening 1420. When the placement section 1410 closes the placement unit opening 1420, the placement section 1410 may be set to form the lower surface of the placement unit internal space 1401.

[0307] The placement section 1410 may include: a placement surface 1411 for placing solid detergents when the placement section 1410 closes the placement unit 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 unit opening 1420.

[0308] As an example, the placement unit opening 1420 may be defined as the surface closed by the placement section 1410 in the placement unit internal space 1401. Thus, the area above the upper surface of the placement unit opening 1420 may be defined as the placement unit internal space 1401, and the area below the lower surface of the placement unit opening 1420 may be defined as the discharge guide 1430. When the placement section 1410 closes the placement unit opening 1420, the placement surface 1411 may be arranged on the placement unit opening 1420. Thus, the placement surface 1411 may be defined as the lower surface of the placement unit internal space 1401.

[0309] As an example, the lower surface of the placement unit internal space 1401 may be defined as the placement unit opening 1420, but when the placement section 1410 closes the placement unit opening 1420, the lower surface of the placement unit internal space 1401 may be defined as the placement section 1410.

[0310] The placement section 1410 may be set to seal the placement unit internal space 1401 from the outside when the placement section 1410 closes the placement unit opening 1420, and to connect the placement unit internal space 1401 to the tub 120 when the placement section 1410 opens the placement unit opening 1420.

[0311] The placement unit 1400 may include: a placement section drive unit 1470 configured to open and close the placement section 1410.

[0312] As an example, the placement section drive unit 1470 may include a drive motor and transmission components.

[0313] As an example, the transmission components of the placement section drive unit 1470 may include a plurality of gears. As an example, when the drive 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 the received rotational force to open the placement unit opening 1420 from the state of closing the placement unit opening 1420.

[0314] As an example, when the drive motor rotates in the reverse direction, multiple gears can transmit the rotational force in the reverse direction to the placement unit 1410. The placement unit 1410 can rotate in the reverse direction by the received rotational force so that the placement unit 1410 closes the placement unit opening 1420 from the state of opening the placement unit opening 1420.

[0315] The placement unit opening 1420 can communicate with the input port 1122 through the discharge guide 1430. A solid detergent located in the internal space 1401 of the placement unit can be discharged from the internal space 1401 of the placement unit through the placement unit opening 1420, discharged from the placement unit opening 1420 through the input port 1122 to the outside of the automatic detergent input device 1000, and then input into the bucket 12.

[0316] The placement unit 1400 may include: a discharge guide 1430 formed between the placement unit opening 1420 and the input port 1122 to guide the solid detergent to move from the placement unit opening 1420 to the input port 1122.

[0317] A solid detergent discharged from the storage chamber 1200 can be temporarily placed in the placement unit 1400. Specifically, the solid detergent can be located on the placement surface 1411 of the placement unit 1410 that forms the lower surface of the internal space 1401 of the placement unit.

[0318] The input port 1122 can be configured to be opened and closed by the input port cover 1150. The solid detergent discharged along the discharge guide 1430 opens the input port 1122 by pressing the input port cover 1150.

[0319] The solid detergent can move through the input port 1120 and into the bucket 12 while pressing the input port cover 1150.

[0320] When the placement unit 1410 opens the placement unit opening 1420, the solid detergent arranged on the placement unit 1410 can move downward by gravity and be discharged to the outside of the internal space 1401 of the placement unit through the placement unit opening 1420.

[0321] The automatic detergent input device 1000 can be configured such that when a solid detergent discharged from the storage chamber 1200 moves to the outside of the storage chamber 1200, it is not immediately discharged to the outside of the automatic detergent input device 1000, but is discharged to the outside of the automatic detergent input device 1000 through the placement unit 1400.

[0322] The storage chamber 1200 may include an intermediate door 1250 configured to open and close the storage chamber discharge port 1210. The intermediate door 1250 may be configured such that solid detergent does not discharge from the storage chamber 1200 by the pusher 1300, and restricts the solid detergent loaded in the storage chamber 1200 from moving to the placement part 1400 by an external force.

[0323] The intermediate door 1250 may be configured to be biased in a direction to close the storage chamber discharge port 1210. The intermediate door 1250 may include an elastic member 1251 and be biased toward the storage chamber discharge port 1210 by the elastic member 1251, so that the intermediate door 1250 can close the storage chamber discharge port 1210.

[0324] Among the plurality of solid detergents loaded into the storage chamber 1200, the solid detergent pressurized and moved to the storage chamber discharge port 1210 by the pusher 1300 is configured to open the intermediate door 1250 while pressurizing the intermediate door 1250. As the intermediate door 1250 is opened, the solid detergent can move to the placement part 1400 through the storage chamber discharge port 1210.

[0325] Even if the solid detergent moves to the storage chamber discharge port 1210 side by an external force rather than by the pressurization of the pusher 1300, the solid detergent may be blocked by the intermediate door 1250, so that the solid detergent cannot pass through the storage chamber discharge port 1210 and does not detach from the storage chamber 1200.

[0326] When the solid detergent moves and collides with the intermediate door 1250 by the pressurizing part 1312a, the pusher 1300 can pressurize the solid detergent so that the biased intermediate door 1250 can be opened by the pressurization of the solid detergent.

[0327] The force with which the intermediate door 1250 closes the storage chamber discharge port 1210 by the elastic member 1251 may be set to be approximately less than the force with which the solid detergent pressurizes the intermediate door 1250 by the pressurization of the pusher 1300.

[0328] The storage chamber discharge port 1210 may not be directly connected to the tub 12, and by forming a placement part 1400 between the storage chamber discharge port 1210 and the tub 12, the storage chamber discharge port 1210 may be configured to be connected to the tub 12 through the placement part 1400.

[0329] When the storage chamber discharge port 1210 is directly connected to the tub 12, the water remaining in the tub 12 flows into the interior of the storage chamber 1200 through the storage chamber discharge port 1210 by using the storage chamber discharge port 1210. Thus, the plurality of solid detergents loaded inside the storage chamber 1200 may be damaged or deformed by the water.

[0330] To prevent this, the outlet 1210 of the storage chamber can be set to not be directly connected to the tub 12 and be indirectly connected to the tub 12 through the placement unit 1400.

[0331] The placement unit 1400 can be set to open the placement unit opening 1420 only when the solid detergent is put into the tub 12, so that the inner space 1401 of the placement unit communicates with the tub 12. In the stage when the solid detergent is not put into the interior of the tub 12, the placement unit 1410 can close the placement unit opening 1420 to minimize the situation where the water remaining in the tub 12 flows into the inner space 1401 of the placement unit.

[0332] The placement unit 1400 can include: a placement unit sensor 1440 that senses whether the solid detergent is placed in the placement unit 1400.

[0333] As the storage chamber 1200 is set to communicate with the placement unit 1400, the solid detergent discharged from the storage chamber 1200 must be sensed by the placement unit sensor 1440 to determine whether the solid detergent is placed in the placement unit 1400.

[0334] The placement unit sensor 1440 can be set as a position sensor. As an example, the placement unit sensor 1440 can include an optical sensor.

[0335] The placement unit sensor 1440 can sense whether the solid detergent is located in the placement unit 1400, and the control device 1900 of the dishwasher 1 (refer to Figure 5 ) can control the detergent automatic input device 1000 based on the value sensed by the placement unit sensor 1440.

[0336] The control device 1900 can receive information related to whether the solid detergent is loaded into the storage chamber 1200, whether the detergent is placed in the placement unit 1400 after the pusher 1300 is driven in the state where the solid detergent is loaded into the storage chamber 1200, and whether the detergent is discharged from the placement unit 1400 after the solid detergent is placed in the placement unit 1400, and control the detergent automatic input device 1000 based on this.

[0337] The control device 1900 can be set to communicate with the main control device of the dishwasher 1, so as to control the control unit to control the dishwasher 1 based on the received information.

[0338] As an example, the control device 1900 and the main control device are subordinate structures of the control unit, and both the dishwasher 1 and the detergent automatic input device 1000 can be set to be controlled by the control unit. However, in the following description, for the control of the detergent automatic input device 1000, it is assumed that the detergent automatic input device 1000 is controlled by the control device 1900.

[0339] As an example, when the placement sensor 1440 does not sense solid detergent after the ejector 1300 is driven, the control device 1900 can determine that the solid detergent is not loaded into the storage chamber 1200, and thus the solid detergent is not discharged from the storage chamber 1200, or it can determine that when the solid detergent is loaded into the storage chamber 1200, the solid detergent is not discharged from the storage chamber 1200 due to the malfunction of the ejector 1300, and the automatic detergent injection device 1000 can be controlled on this basis.

[0340] As an example, control device 1900 may control ejector 1300 to drive ejector 1300 again so that solid detergent moves to seating portion 1400. In addition, control device 1900 may communicate with the main control device, and the control portion may control dishwasher 1 based on the communication value to prevent the process of dishwasher 1 from proceeding.

[0341] As an example, after the control device 1900 controls the ejector 1300 in a manner of driving the ejector 1300 again, in a case where the seating portion sensor 1440 cannot continuously sense the solid detergent, the control device 1900 may communicate with the main control device, and the control portion may control the dishwasher 1 based on the communication value to prevent the process of the dishwasher 1 from being performed. In addition, the control portion may control the display to notify the user of the situation that there is no solid detergent in the storage chamber 1200.

[0342] 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.

[0343] As an example, since the placement part sensor 1440 senses the solid detergent in the placement part, in the case where the solid detergent is not sensed after the sensing state is maintained, the control device 1900 can 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 on this basis, control the automatic detergent injection device 1000. As an example, the control device 1900 can communicate with the main control device, and the control part can control the dishwasher 1 based on the communication value to perform the washing stroke of the dishwasher 1.

[0344] As the placement unit sensor 1440 senses the position of the solid detergent in the placement unit 1400, the control device 1900 can be set to recognize all of the above situations, so that the number of sensors for sensing the position of the solid detergent can be further minimized. That is, the control device 1900 can determine whether the solid detergent is located in the storage chamber 1200, the internal space 1401 of the placement unit, or outside the placement unit 1400 only by the arrangement of the placement unit sensor 1440 in the placement unit 1400, without further position sensors for sensing the position of the solid detergent at positions such as the storage chamber 1200 or the discharge guide 1430. This will be described in detail later.

[0345] As described above, the storage chamber 1200 can be provided in multiple. As an example, the storage chamber 1200 can be provided in two.

[0346] Hereinafter, for the sake of convenience of description, Figure 8 Based on this, the storage chamber 1200 arranged on the left side along the second direction Y is defined as the first storage chamber 1200, and the storage chamber 1200' arranged on the right side along the second direction Y is defined as the second storage chamber 1200'. In addition, the structure of the first storage chamber 1200 is defined as the first structure, and the structure of the second storage chamber 1200' is defined as the second structure. 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'.

[0347] In addition, the ejector that discharges the solid detergent stored in the first storage chamber 1200 is defined as the first pusher 1300, and the ejector that discharges the solid detergent stored in the second storage chamber 1200' is defined as the second pusher 1300'. In addition, the holder 1500 arranged inside the first storage chamber 1200 is defined as the first holder 1500, and the holder 1500 arranged in the second storage chamber 1200' is defined as the second holder 1500'.

[0348] The first storage chamber 1200 and the second storage chamber 1200' can be arranged separately at intervals along the second direction Y. The first storage chamber 1200 and the second storage chamber 1200' each include a long side extending in the third direction Z when the detergent automatic input device 1000 is arranged at the first position 1000A. Therefore, only by being separated at intervals along the second direction Y can the first storage chamber 1200 and the second storage chamber 1200' be effectively arranged inside the detergent automatic input device 1000.

[0349] When the user loads the solid detergent into the detergent automatic input device 1000, a larger amount of solid detergent can be loaded at one time by means of the first storage chamber 1200 and the second storage chamber 1200'.

[0350] The placement unit 1400 can be arranged between the first storage chamber 1200 and the second storage chamber 1200' along the second direction Y. As described above, the first storage chamber 1200 can be set to communicate with the placement unit 1400, and the second storage chamber 1200' can also be set to communicate with the placement unit 1400.

[0351] Thus, the first storage chamber 1200 and the second storage chamber 1200' can communicate with the barrel 12 through a placement unit 1400 arranged between the first storage chamber 1200 and the second storage chamber 1200' along the second direction Y.

[0352] This is to minimize the situation where the detergent automatic feeding device 1000 extends along the second direction Y as the first storage chamber 1200 and the second storage chamber 1200' share the placement unit 1400. That is, when multiple placement units 1400 are set to correspond to the first storage chamber 1200 and the second storage chamber 1200', the volume of the detergent automatic feeding device 1000 can increase in the second direction Y by means of the multiple placement units. As described above, for the detergent automatic feeding device 1000, the first storage chamber 1200 and the second storage chamber 1200' are set to communicate through a single placement unit 1400, so that the length of the detergent automatic feeding device 1000 in the second direction Y can be minimized.

[0353] Taking Figure 8 as a reference, the first storage chamber 1200 can be arranged on the left side of the placement unit 1400 along the second direction Y, and the second storage chamber 1200' can be arranged on the right side of the placement unit 1400.

[0354] As described above, while rotating in the clockwise direction, the first cam member 1310 moves the solid detergent placed on the first lower surface 1220 of the first storage chamber 1200 to the right side of the first storage chamber 1200. As the first storage chamber discharge port 1210 is arranged below the first right side surface 1230 of the first storage chamber 1200, the solid detergent can move to the placement unit 1400 arranged on the right side of the first storage chamber 1200.

[0355] The first cam member 1310 can be set to be linked with the first drive motor 1320 and the first transmission member 1330 and rotate in the clockwise direction.

[0356] On the contrary, the second cam member 1310' can rotate in the counterclockwise direction. Different from the first ejector 1300, the second ejector 1300' can be set to move the solid detergent loaded into the second storage chamber 1200' to the left.

[0357] The second cam member 1310' can be set to rotate counterclockwise in linkage with the second drive motor 1320' and the second transmission member 1330'.

[0358] While rotating counterclockwise, the second cam member 1310' can move the solid detergent placed on the second lower surface 1220' of the second storage chamber 1200' to the left side of the second storage chamber 1200'. As the second storage chamber discharge port 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 part 1400 arranged on the left side of the second storage chamber 1200'.

[0359] The second storage chamber 1200' can include: a second through portion 1221', formed on the second lower surface 1220' of the second storage chamber 1200', and set such that the second pressing portion 1312a' moves from the outside of the second storage chamber 1200' to the inside of the second storage chamber 1200'.

[0360] The second through portion 1221' can be set to extend not only to the second lower surface 1220' of the second storage chamber 1200', but also to the lower parts of the second right side surface 1230' and the second left side surface 1240' of the second storage chamber 1200'.

[0361] The second pressing portion 1312a' can rotate by the rotation of the second cam member 1310', move into the inside of the second storage chamber 1200' through the second through portion 1221' of the lower part of the second right side surface 1230' and the second lower surface 1220', and can move out of the second storage chamber 1200' through the second through portion 1221' of the lower part of the second left side surface 1240' and the second lower surface 1220' as the second cam member 1310' rotates.

[0362] The second pressing portion 1312a' can be set to rotate while pressing the solid detergent placed on the second lower surface 1220' to move the solid detergent to the left side.

[0363] The first rotation shaft 1313 of the first cam member 1310 can be arranged 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 shaft 1313 of the first cam member 1310 can be arranged 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.

[0364] The second rotation axis 1313' of the second cam member 1310' can 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' can be disposed at the center 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.

[0365] As described above, the reason why the first rotation axis 1313 of the first cam member 1310 and the second rotation axis 1313' of the second cam member 1310' are respectively disposed at the centers of the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y is that when the first pressing portion 1312a of the first cam member 1310 and the second pressing portion 1312a' of the second cam member 1310' rotate, they can stably support the solid detergent and apply pressure.

[0366] When the first rotation axis 1313 of the first cam member 1310 and the second rotation axis 1313' of the second cam member 1310' are respectively disposed outside the centers of the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y, in the section where the first pressing portion 1312a and the second pressing portion 1312a' penetrate through the first through portion 1221 and the second through portion 1221' by the rotation of the first cam member 1310 and the second cam member 1310', the first pressing portion 1312a and the second pressing portion 1312a' penetrate through the first through portion 1221 and the second through portion 1221' in a manner less than or equal to a predetermined length, so it may be difficult to stably support the solid detergent.

[0367] In the section where the first pressing portion 1312a and the second pressing 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 pressing portion 1312a and the second pressing portion 1312a' penetrate through the first through portion 1221 and the second through portion 1221' in a manner less than or equal to a predetermined length, so it may not be possible to stably press the solid detergent loaded in the first storage chamber 1200 and the second storage chamber 1200'.

[0368] To prevent this, the first rotation axis 1313 of the first cam member 1310 and the second rotation axis 1313' of the second cam member 1310' can be arranged to be respectively centered in the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y, so that in the interval where the first pressing portion 1312a and the second pressing 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 pressing portion 1312a and the second pressing portion 1312a' penetrate and rotate with a length greater than or equal to a predetermined length.

[0369] In addition, when the first rotation axis 1313 of the first cam member 1310 and the second rotation axis 1313' of the second cam member 1310' are not respectively centered in the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y, due to the increase in the volume of the automatic detergent dispensing device 1000 in the second direction Y, it is preferably that the first rotation axis 1313 of the first cam member 1310 and the second rotation axis 1313' of the second cam member 1310' are respectively centered in the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y.

[0370] The first pusher 1300 and the second pusher 1300' can be arranged to be driven in directions that are mirror-symmetrical about the placement portion 1400 in the second direction Y. The first cam member 1310 and the second cam member 1310' can be arranged to rotate in opposite directions so as to be mirror-symmetrical about the placement portion 1400.

[0371] The first storage chamber 1200 and the second storage chamber 1200' are arranged on both sides of the placement portion 1400 in the second direction Y. Since all the solid detergents discharged from the first storage chamber 1200 and the second storage chamber 1200' must move to the placement portion 1400, the first pusher 1300 and the second pusher 1300' can be driven to be mirror-symmetrical about the placement portion 1400 in the second direction Y.

[0372] The width L1 (or can be referred to as the lateral length) of the first storage chamber 1200 and the width L1 of the second storage chamber 1200' in the second direction Y can be set to be substantially the same.

[0373] The widths L1 of the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y and the width L3 of the placement portion 1400 can be set to be approximately 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 widths 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 possible to be placed on the placement section 1410 and may be in a state of being stuck in the inner space 1401 of the placement portion.

[0374] Conversely, when the width L3 of the placement portion 1400 in the second direction Y is formed to be much larger than the widths L1 of the first storage chamber 1200 and the second storage chamber 1200', since the volume of the placement portion 1400 in the second direction Y increases to an excessive extent, there may be a problem that the volume of the detergent automatic feeding device 1000 in the second direction Y increases to an excessive extent.

[0375] Therefore, as described above, preferably, the width L3 of the placement portion 1400 is formed to have a length corresponding to the width L1 of the first storage chamber 1200 and the second storage chamber 1200' in the second direction Y, where the first storage chamber 1200 and the second storage chamber 1200' have a cross-sectional area S considering the size of the solid detergent.

[0376] Hereinafter, the driving of the detergent automatic feeding device 1000 will be described in detail.

[0377] Figure 8 It is a diagram showing a state in which a part of the detergent automatic feeding device of a dishwasher according to an embodiment is removed. Figure 9 It shows Figure 8 a state in which the solid detergent loaded in the first storage chamber is discharged from the first storage chamber. Figure 10 It shows Figure 9 a state in which the solid detergent is placed in the placement portion. Figure 11 It shows Figure 10 a state in which the solid detergent is discharged from the detergent automatic feeding device. Figure 12 It shows Figure 8 a state in which the solid detergent loaded in the second storage chamber is discharged from the second storage chamber.

[0378] As Figure 8 and Figure 9 shown, the control device 1900 can control the first pusher 1300 or the second pusher 1300' so that one of the plurality of solid detergents stacked in any one of the first storage chamber 1200 and the second storage chamber 1200' moves to the placement portion 1400.

[0379] As an example, the control device 1900 can control the first pusher 1300 to drive the first pusher 1300. The control device 1900 can control the first pusher 1300 to drive the first pusher 1300 again based on the sensed value of the placement unit sensor 1440, or control the second pusher 1300' to drive the second pusher 1300', which will be described in detail later.

[0380] The control device 1900 can control the first pusher 1300 to drive the first drive motor 1320 to rotate the first cam member 1310 in the clockwise direction.

[0381] The control device 1900 can control the second pusher 1300' to drive the second drive motor 1320' to rotate the second cam member 1310' in the clockwise direction.

[0382] The control device 1900 can control the position of the first cam member 1310 so that the first cam region 1310A1 of the first cam member 1310 is arranged at the upper end in the third direction Z before the first pressing portion 1312a moves into the interior of the storage chamber 1200 by the rotation of the first cam member 1310.

[0383] 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 can be arranged below the first support 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 can be stably placed on the first support surface 1222, so that the first pressing portion 1312a can stably move the solid detergent in the second direction Y by the rotation of the first cam member 1310.

[0384] As an example, when a part of the first cam member 1310 protrudes above the first support surface 1222 in the third direction Z through the first through hole 1221, the lowermost solid detergent in the third direction Z among the plurality of solid detergents loaded in the first storage chamber 1200 cannot be horizontally arranged in the third direction Z. Thus, when the solid detergent moves in the second direction Y, instead of moving in the second direction Y due to the center of gravity, it moves in other directions such as rotation, which causes the solid detergent not to move toward the first storage chamber discharge port 1210 and cannot be discharged to the outside of the first storage chamber 1200.

[0385] Thus, the control device 1900 can control the position of the first cam member 1310 so that when the dishwasher 1 is not driven into the washing stroke, the first cam area 1310A1 of the first cam member 1310 is arranged at the upper end in the third direction Z. Then, when the dishwasher 1 is driven into the washing stroke, it can communicate with the main control device, and based on the communication value, the control device 1900 can control the first ejector 1300 so that the first cam member 1310 rotates in the clockwise direction.

[0386] The first pressurizing part 1312a moves into the first storage chamber 1200 in conjunction with the rotation of the first cam member 1310, so that the solid detergent at the bottom in the third direction Z can be moved to the right with reference to the second direction Y by the first pressurizing part 1312a.

[0387] The solid detergent may be pressurized by the first pressurizing part 1312a and moved to the first storage chamber discharge outlet 1210 , and the solid detergent may be discharged to the outside of the first storage chamber 1200 through the first storage chamber discharge outlet 1210 while opening the first middle door 1250 closing the first storage chamber discharge outlet 1210 .

[0388] Then, if Figure 10 As shown, the solid detergent may be arranged on the placement portion 1400 , and more specifically, may be arranged on the placement portion 1410 .

[0389] The seating section sensor 1440 may sense the position of the solid detergent to determine whether the solid detergent is located on the seating section inner space 1401. Specifically, the seating section sensor 1440 may be arranged on the seating section 1410 along the third direction Z and sense whether the solid detergent is located on the seating section 1410.

[0390] The control device 1900 can receive the information of the location of the solid detergent on the placement part 1410 through the placement part sensor 1440 and communicate with the main control device. The control part can control the dishwasher 1 based on the communicated value so that the dishwasher 1 performs the washing process.

[0391] As an example, the washing process of the dishwasher 1 may be divided into a pre-wash step, a main wash step, a rinsing step, and a drying step. The control unit may control the dishwasher 1 based on the communicated value so that the dishwasher 1 performs the pre-wash step.

[0392] As an example, when the placement unit sensor 1440 does not detect the solid detergent after the control device 1900 drives the first pusher 1300 once, the control device 1900 can send the information that the solid detergent is not detected to the main control device, and the control unit can control the dishwasher 1 based on the communicated value so that the dishwasher 1 does not execute the pre-washing step of the washing cycle. This is because in some cases, the user can open the door 20 to load the solid detergent into the detergent automatic feeding device 1000. Therefore, when the solid detergent is not arranged in the placement unit 1400, the control unit can control the dishwasher 1 not to start the washing cycle.

[0393] As an example, different from Figure 10 when the placement unit sensor 1440 does not detect the solid detergent after the first pusher 1300 is driven once, the control device 1900 can be set to drive the first pusher 1300 one more time on this basis. As described above, the control unit can control the dishwasher 1 so that the dishwasher 1 does not execute the washing cycle.

[0394] This is because when the lowermost solid detergent in the third direction Z among the multiple solid detergents loaded into the first storage chamber 1200 cannot be stably placed on the first support surface 1222 and cannot move along the second direction Y by the first pressing part 1312a, but moves in other directions and cannot move to the first storage chamber discharge port 1210, by driving the first pusher 1300 again, the solid detergent can be made to move along the second direction Y again by the first pressing part 1312a, so as to discharge it to the outside of the first storage chamber 1200.

[0395] Then, the control device 1900 can receive the information about the position of the solid detergent on the placement unit 1410 through the placement unit sensor 1440 and communicate with the main control device, and the control unit can control the dishwasher 1 based on the communicated value so that the dishwasher 1 executes the washing cycle.

[0396] As Figure 11 shown, the control device 1900 can open the placement unit 1410 so that when the dishwasher 1 is driven by the control unit to the main washing step during the washing cycle, the solid detergent can be discharged from the inner space 1401 of the placement unit and is put into the tub 12 through the discharge guide 1430.

[0397] The placement unit 1410 opens the placement unit opening 1420, and the solid detergent can move through the placement unit opening 1420 to the discharge guide 1430 and is discharged from the detergent automatic feeding device 1000 through the inlet 1122 along the discharge guide 1430.

[0398] As an example, the placement unit 1410 can open the placement unit opening 1420 while rotating downward, and the solid detergent disposed on the placement unit 1410 can move through the placement unit opening 1420 to the discharge guide 1430 while moving downward as the placement unit 1410 rotates.

[0399] The control device 1900 can rotate the placement unit 1410 to open the placement unit opening 1420. After a predetermined time has elapsed, the placement unit 1410 can rotate in the opposite direction of the placement unit 1410 to close the placement unit opening 1420 again.

[0400] This is because when the placement unit opening 1420 is open for a predetermined time, water can flow in from the tub 12, and the water can flow into the storage chamber 1200 through the placement unit 1400. To prevent this, the control device 1900 can control the opening and closing of the placement unit 1410.

[0401] The control device 1900 can control the placement unit driving unit 1470 to open and close the placement unit 1410. The placement unit driving unit 1470 can transmit a rotational force to the placement unit 1410 in one direction or in the opposite direction under the control of the control device 1900 to drive the placement unit 1410 to open and close the placement unit opening 1420.

[0402] After the control device 1900 controls the placement unit 1410 to open and close the placement unit 1410, when receiving information that the solid detergent is not located in the placement unit 1400 from the placement unit sensor 1440, it can communicate with the main control device, and the control unit can control the dishwasher 1 based on the communicated value so that the dishwasher 1 performs the main washing step during the washing cycle.

[0403] This is to prevent the following situation: Even when the placement unit 1410 opens and closes the placement unit opening 1420, due to adhesion of the solid detergent to the placement unit 1410 or other reasons, the dishwasher 1 performs the main washing step without detaching from the inner space 1401 of the placement unit.

[0404] After the control device 1900 controls the placement unit 1410 to open and close the placement unit 1410, it can receive information that the solid detergent is not located in the placement unit 1400 from the placement unit sensor 1440 and control the position of the first cam member 1310 so that the first cam region 1310A1 of the first cam member 1310 is arranged at the upper end in the third direction Z.

[0405] Thus, the lowermost solid detergent among the multiple solid detergents in the third direction Z can be discharged to the outside of the first storage chamber 1200, and at the same time, the multiple solid detergents loaded in the first storage chamber 1200 can move downward so that the solid detergent directly above the discharged solid detergent can be stably arranged on the support surface 1222.

[0406] The control device 1900 can control the automatic detergent input device 1000 to automatically input solid detergent into the tub 12 when the dishwasher 1 is driven for a washing cycle by repeating the above process.

[0407] When the control device 1900 receives information from the placement sensor 1440 that no solid detergent is sensed after driving the first pusher 1300, as described above, the control device 1900 can also drive the first pusher 1300 one more time and then receive information from the placement sensor 1440 regarding whether solid detergent is sensed.

[0408] At this time, when the control device 1900 still receives information from the placement sensor 1440 that no solid detergent is sensed after driving the first pusher 1300 one more time, the control device 1900 can be set to drive the second pusher 1300' on this basis.

[0409] This is because when the placement sensor 1440 still does not sense the solid detergent after the control device 1900 controls the first pusher 1300 to drive the first pusher 1300 twice, all the multiple solid detergents loaded in the first storage chamber 1200 may have been discharged from the first storage chamber 1200.

[0410] Thus, the control device 1900 can control the second pusher 1300' to drive the second pusher 1300'. Since the feature of the control device 1900 driving the second pusher 1300' is the same as that of the control device 1900 driving the first pusher 1300, repeated descriptions are omitted.

[0411] In addition, as Figure 10 and Figure 11 shown, after the pressing part 1312a presses the lowermost solid detergent among the multiple solid detergents by the rotation of the cam member 1310, while the pressing part 1312a disengages from the outside of the storage chamber 1200, the multiple solid detergents can move downward in parallel with respect to the third direction Z in a stacked state.

[0412] The cam member 1310 can be configured to guide a plurality of solid detergents stacked and loaded inside the storage chamber 1200 to move parallel to the third direction Z. More specifically, as the cam member 1310 rotates, it can be configured to guide a plurality of solid detergents disposed at the edge of the cam member 1310 to gradually descend inside the storage chamber as the cam member 1310 rotates.

[0413] As described above, with reference to Figures 1 to 12 , the structure and operation of the detergent automatic input device 1000 of the dishwasher 1 according to an embodiment of the present disclosure have been described. However, the idea of the present disclosure is not limited thereto, and the above-described content is only an example of a dishwasher and its detergent automatic input device according to the idea of the present disclosure.

[0414] For example, when the detergent automatic input device 1000 is located at the first position 1000A, a plurality of solid detergents can be stacked and loaded inside the storage chamber 1200 in a direction different from the third direction Z (i.e., a direction different from the up-down direction of the dishwasher 1).

[0415] As an example, when the detergent automatic input device 1000 is located at the first position 1000A, the detergent automatic input device 1000 can include: a storage chamber having a long side extending along the second direction Y which is the left-right direction of the dishwasher 1, and a plurality of solid detergents can be configured to be stacked and loaded inside the storage chamber along the second direction Y. The detergent automatic input device 1000 can include: a holder that moves a plurality of solid detergents stacked along the second direction Y inside the storage chamber along the second direction Y. For example, the holder can include an elastic member such that a plurality of solid detergents move along the second direction Y toward the cam member of the ejector. The cam member can press one of the plurality of solid detergents to move it outside the storage chamber. For example, it can be discharged and moved below the storage chamber in a direction orthogonal to the second direction Y. One solid detergent discharged outside the storage chamber can be input into the tub 12 through a placement portion or the like.

[0416] Alternatively, as an example, as Figures 1 to 12 shown, the detergent automatic input device 1000 can include: storage chambers 1200, 1200' configured to stack and load a plurality of solid detergents along the third direction Z when the detergent automatic input device 1000 is located at the first position 1000A. However, compared with Figures 1 to 12Different from that shown in , the automatic detergent injection device 1000 can be configured so that multiple solid detergents move upward and are discharged inside the storage chamber 1200, 1200'. The automatic detergent injection device 1000 may include a retaining member arranged inside the storage chamber 1200, 1200' and moving the multiple solid detergents upward. For example, the retaining member may include an elastic member so that the multiple solid detergents can move upward. A cam of an injector may be arranged on the upper side of the storage chamber 1200, 1200', and the cam of the injector can be used to move the solid detergent arranged at the top of the multiple solid detergents to the outside of the storage chamber 1200. A solid detergent moved to the outside of the storage chamber 1200 can be injected into the barrel 12 through a placement portion, etc.

[0417] In addition, it is explained that when the automatic detergent feeding device 1000 is located in the first position 1000A, a plurality of solid detergents are stacked along a third direction Z as the up-down direction and loaded into the storage chamber 1200, 1200'. The term "third direction" indicating 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 expressions such as "third". For example, as needed, the stacking direction of the plurality of solid detergents can be referred to as the "first direction", in which case the term "first direction" refers 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 in the first position 1000A). The cross-sectional area of ​​the storage chamber 1200 according to an example will be described in detail below.

[0418] Figure 13 is a diagram showing a portion of a storage chamber and a holder when the automatic detergent injection device is arranged at a first position in a dishwasher according to an embodiment, Figure 14 It is schematically shown Figure 13 Figure 1. A diagram of a portion of a guide rail and a retainer, Figure 15 is a diagram showing a portion of a storage chamber and a holder when the automatic detergent injection device is arranged at a second position in a dishwasher according to an embodiment, Figure 16 It is schematically shown Figure 15 FIG. 1 is a diagram of a portion of a guide rail and a retaining member.

[0419] As an example, the holder 1500 may be provided as a plurality of holders 1500, 1500' in a number corresponding to the plurality of storage chambers 1200, 1200'. Figure 13 As shown, the description is made based on one retaining member 1500.

[0420] As described above, the storage chamber 1200 may include: guide rails 1290 that guide the holder 1500 to move inside the storage chamber 1200.

[0421] As Figure 13 and Figure 14 shown, the guide rails 1290 may be configured to extend along the direction in which a plurality of solid detergents are stacked. The guide rails 1290 may be configured to extend in the direction in which the long side 1201 of the storage chamber 1200 extends. The guide rails 1290 may be configured to extend in the third direction Z, which is the up-and-down direction, when the detergent automatic feeding device 1000 is arranged at the first position 1000A.

[0422] As described above, the holder 1500 may include: guide protrusions 1510 that are configured to be inserted into the guide rails 1290 and can move in the extending direction of the guide rails 1290.

[0423] As an example, the guide rails 1290 may be respectively formed on the right side surface 1230 and the left side surface 1240 of the storage chamber 1200 and configured as a pair. As an example, the guide rails 1290 may be configured to be formed on the inner surface 1260 of the storage chamber 1200.

[0424] As an example, the guide protrusions 1510 may be configured as a pair corresponding to the pair of guide rails 1290. The pair of guide protrusions 1510 may be configured to protrude from the holder 1500 to the left and to the right respectively 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.

[0425] The holder 1500 may be configured to translate inside the storage chamber 1200 along the direction in which the long side 1201 of the storage chamber 1200 extends.

[0426] The pusher 1300 is arranged on one side 1201a of the long side 1201 with reference to the long side 1201 of the storage chamber 1200 (refer to Figure 7 ), and the holder 1500 may move from the other side of the long side 1201 along the extending direction of the long side 1201 toward the one side 1201a of the long side 1201.

[0427] When the direction in which a plurality of solid detergents are stacked corresponds to the third direction Z, the holder 1500 may be configured to move from the other side 1201b of the long side 1201 toward the plurality of solid detergents by gravity to press the plurality of solid detergents in the direction in which the plurality of solid detergents are stacked.

[0428] The holding member 1500 can be configured to press the uppermost solid detergent Dh among the plurality of solid detergents in the third direction Z by gravity. The plurality of solid detergents can be configured to receive an external force pressed in the stacking direction by the holding member 1500, whereby the stacked arrangement of the plurality of solid detergents can be maintained.

[0429] The guide rail 1290 can include a first side 1291 and a second side 1292. The first side 1291 extends parallel to the extending direction of the guide rail 1290, and the second side 1292 is arranged at a distance from the first side 1291 in a direction orthogonal to the extending direction of the guide rail 1290.

[0430] A guide groove 1294 is formed between the first side 1291 and the second side 1292 and is configured to allow the guide projection 1510 to be inserted into the guide groove 1294.

[0431] The second side 1292 can be configured to be arranged on the lower side of the first side 1291 in the third direction Z when the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z due to the opening of the door 20.

[0432] The second side 1292 can be arranged in front of the first side 1291 in the first direction X. Accordingly, when the door 20 is opened, the second side 1292 can be arranged on the lower side of the first side 1291 in the third direction Z.

[0433] The locking portion 1293 can be arranged on the second side 1292. The locking portion 1293 can be configured to restrict the movement of the holding member 1500 in the stacking direction of the plurality of solid detergents when the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z due to the opening of the door 20.

[0434] As an example, the locking portion 1293 can be configured to protrude from the second side 1292 in the direction towards the first side 1291.

[0435] As an example, the locking portion 1293 can include a guiding portion 1293a that extends obliquely with respect to the second side 1292, and a supporting portion 1293b that extends from the guiding portion 1293a to the second side 1292. When the detergent automatic feeding device 1000 is arranged at the first position 1000A, the guiding portion 1293a can be configured to be arranged above the supporting portion 1293b.

[0436] The guiding portion 1293a can be configured to extend obliquely downward from the second side 1292 when the detergent automatic feeding device 1000 is arranged at the first position 1000A. The supporting portion 1293b can be configured to extend from the lower end of the guiding portion 1293a in the third direction Z towards the second side 1292.

[0437] The support portion 1293b may be configured to extend in the third direction Z from the lower end of the guide portion 1293a toward the second side 1292 in such a manner that the inclination angle of the support portion 1293b with respect to the second side 1292 is greater than the inclination angle of the guide portion 1293a.

[0438] When the automatic detergent dispenser 1000 is disposed at the first position 1000A, the holder 1500 moves downward due to gravity, and the guide protrusion 1510 can move downward along the guide groove 1294.

[0439] As an example, the guide protrusion 1510 can move downward along the guide groove 1294 without contacting the first side 1291 and the second side 1292.

[0440] As an example, when the guide protrusion 1510 moves while being biased toward the first side 1291, the guide protrusion 1510 can be guided by the first side 1291 and move downward.

[0441] As an example, when the guide protrusion 1510 moves while being biased toward the second side 1292, the guide protrusion 1510 can be guided by the guide portion 1293a and move downward.

[0442] When the automatic detergent dispenser 1000 is disposed at the first position 1000A, the holder 1500 can move downward along the guide rail 1290 from the other side 1201b of the long side 1201 with respect to the third direction Z to press the solid detergent closest to the holder 1500 among the plurality of solid detergents, thereby maintaining the stacked arrangement of the plurality of solid detergents. Further, when the lowermost solid detergent among the plurality of solid detergents is discharged to the outside from the storage chamber 1200 by the pusher 1300, the holder 1500 can also continuously press the solid detergent Dh closest to the holder 1500 so that the plurality of solid detergents move downward while maintaining the stacked arrangement.

[0443] The holder 1500 may include a flange 1520 that extends from one side of the holder 1500 toward the plurality of solid detergents in the stacking direction of the plurality of solid detergents.

[0444] The flange 1520 may be configured to overlap a part of the solid detergent Dh closest to the holder 1500 among the plurality of solid detergents in the stacking direction of the plurality of solid detergents.

[0445] As an example, the flange 1520 may extend downward from the lower end of the inner surface 1260 side of the holder 1500 facing the storage chamber 1200.

[0446] The flange 1520 may be configured to contact the inner surface 1260 of the storage chamber 1200.

[0447] When the holder 1500 moves in the stacking direction of the plurality of solid detergents, the flange 1520 may move between the inner surface 1260 of the storage chamber 1200 and one solid detergent Dh arranged closest to the holder 1500.

[0448] The flange 1520 may be configured to stably arrange the holder 1500 above one solid detergent Dh arranged closest to the holder 1500 in the third direction Z.

[0449] The flange 1520 may be configured to contact and move along the inner surface 1260 of the storage chamber 1200 when the holder 1500 moves, so as to prevent the holder 1500 from rotating or moving in other directions different from the stacking direction of the plurality of solid detergents during movement.

[0450] The holder 1500 may include a handle 1530 extending from the holder 1500 toward the storage chamber discharge port 1210.

[0451] As described above, the holder 1500 is configured to move to the lower part of the storage chamber 1200 in the third direction Z. When all the plurality of solid detergents loaded in the storage chamber 1200 are discharged, the holder 1500 may move to the lower surface 1220 of the storage chamber 1200.

[0452] The holder 1500 may move to the lower part of the storage chamber 1200 in the third direction Z by gravity, but when there is no external force due to the locking portion 1293, the holder 1500 cannot move to the upper part of the storage chamber 1200.

[0453] Therefore, when all the plurality of solid detergents loaded in the storage chamber 1200 are discharged, the holder 1500 may be arranged on the lower surface 1220 of the storage chamber 1200 and may maintain its position.

[0454] When all the plurality of solid detergents loaded in the storage chamber 1200 are discharged and the user loads a new solid detergent into the storage chamber, the user may hold the handle 1530 and easily move the holder 1500 to the other side 1201b of the long side 1201.

[0455] The storage chamber 1200 may include: an auxiliary guide rail 1295, which guides the holder 1500 to move inside the storage chamber 1200 and is arranged separately from the guide rail 1290. When the detergent automatic feeding device 1000 is arranged at the first position 1000A, the auxiliary guide rail 1295 may be arranged separately from the guide rail 1290 in the first direction X.

[0456] The auxiliary guide rail 1295 may extend in the same extending direction as the guide rail 1290. The auxiliary guide rail 1295 may be configured to extend in the extending direction of the long side 1201 of the storage chamber 1200.

[0457] The holder 1500 may include an auxiliary guiding protrusion 1540 inserted into the auxiliary guide rail 1295. The auxiliary guiding protrusion 1540 may be inserted into the auxiliary guide rail 1295 and may move in the extending direction of the auxiliary guide rail 1295.

[0458] The auxiliary guide rail 1295 includes two sides extending parallel to the extending direction of the auxiliary guide rail 1295 and an auxiliary guiding groove formed between the two sides. The auxiliary guiding protrusion 1540 may be inserted into the auxiliary guiding groove and guided by the auxiliary guide rail 1295 to linearly move.

[0459] The holder 1500 may include a counterweight member 1550 configured to have a weight greater than a predetermined weight to move in the third direction Z by gravity. As an example, the counterweight member 1550 may be integrally configured with the holder 1500. As an example, the weight member 1550 may be configured to be coupled with the holder 1500.

[0460] As an example, the holder 1500 may be configured using a heavy material without including the weight member 1550 to have a weight greater than a predetermined weight.

[0461] The holder 1500 is configured to have a weight greater than a predetermined weight and may be configured to press downward on a plurality of solid detergents with respect to the third direction Z.

[0462] As shown in Figure 15 and Figure 16 When the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z due to the opening of the door 20, the holder 1500 may be configured such that the movement in the stacking direction of the plurality of solid detergents is restricted by the locking portion 1293 and stops at a specific position.

[0463] Accordingly, the movement of the uppermost solid detergent Dh is restricted by configuring to block the movement of the solid detergent Dh arranged closest to the holder 1500 among the plurality of solid detergents, so that the uppermost solid detergent D1 restricts the movement of the other plurality of solid detergents, thereby maintaining the stacked arrangement of the plurality of solid detergents.

[0464] When the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z due to the opening of the door 20, the holder 1500 may be configured to support the uppermost solid detergent Dh among the plurality of solid detergents to maintain the stacked arrangement of the plurality of solid detergents.

[0465] When the stacking direction 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 guide protrusion 1510 can be supported by the support portion 1293b, such that the movement of the guide protrusion 1510 to the other side 1201b of the long side 1201 due to the movement of the door 20 is restricted.

[0466] The guide protrusion 1510 is configured to move to one side 1201a of the long side 1201 by the self-weight of the holder 1500, and, depending on the situation, an external force can be applied in the direction of the other side 1201b of the long side 1201 by the rotation of the door 20. At this time, it can be configured such that the movement in the direction of the other side 1201b of the long side 1201 is restricted by the support portion 1293b, so that the holder 1500 can be prevented from moving in the direction of the other side 1201b of the long side 1201.

[0467] Even if the extending direction of the long side 1201 is oriented in a direction different from the third direction Z due to the opening of the door 20, the holder 1500 is continuously applied with an external force by gravity toward one side 1201a of the long side 1201, and since the movement in the direction of the other side 1201b of the long side 1201 is restricted, it can stay on the upper side of the uppermost solid detergent Dh located in the third direction Z among the plurality of solid detergents.

[0468] Accordingly, when an external force is applied to the uppermost solid detergent Dh among the plurality of solid detergents in a direction different from the direction of one side 1201a of the long side 1201 due to the opening of the door 20, the holder 1500 can be held in a state of staying on the upper side of the solid detergent Dh in the third direction Z, so that the solid detergent Dh can be supported by the holder 1500.

[0469] The holder 1500 can block the movement of the uppermost solid detergent Dh among the plurality of solid detergents to prevent the solid detergent Dh from detaching from the stacked arrangement.

[0470] The lowermost solid detergent in the third direction Z among the plurality of solid detergents is supported by the lower surface 1220 of the storage chamber 1200, and the uppermost solid detergent Dh among the plurality of solid detergents is supported by the holder 1500. Therefore, when the door 20 is opened, the stacked arrangement of the plurality of solid detergents can be maintained even when the detergent automatic feeder 1000 is not arranged at the first position 1000A.

[0471] Hereinafter, the technical features of loading a plurality of solid detergents into the detergent automatic feeder 1000 and the storage chamber lid 1140 of the detergent automatic feeder 1000 opened therefor will be described in detail.

[0472] Figure 17 FIG. is a diagram showing steps of loading solid detergent in a detergent automatic dispensing device of a dishwasher according to an embodiment. Figure 18 It shows Figure 17 the subsequent steps. Figure 19 FIG. is a side sectional view of a detergent automatic dispensing device of a dishwasher.

[0473] As Figure 17 shown, when the user opens the door 20 and the detergent automatic dispensing device 1000 is disposed at the second position 1000B, solid detergent can be loaded into the storage chambers 1200, 1200'.

[0474] The user can 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'.

[0475] The storage chamber covers 1140, 1140' can be configured to open and close the storage chambers 1200, 1200'.

[0476] The storage chamber covers 1140, 1140' can be configured to open the storage chambers 1200, 1200' in a direction orthogonal to the stacking direction of the plurality of solid detergents.

[0477] The storage chamber openings 1121, 1121' can be opened in a direction orthogonal to the stacking direction of the plurality of solid detergents.

[0478] As described above, the storage chamber openings 1121, 1121' can be formed by the housing 1100 as a component of the housing 1100, but are not limited thereto. The storage chamber openings 1121, 1121' can also be defined as a component of the storage chambers 1200, 1200' that opens the storage chambers 1200, 1200' as a component of the storage chambers 1200, 1200'.

[0479] When the detergent automatic dispensing device 1000 is disposed at the first position 1000A, the storage chamber openings 1121, 1121' can be opened toward the first direction X.

[0480] The storage chamber covers 1140, 1140' open and close the storage chamber openings 1121, 1121', and can be opened toward the first direction X when the detergent automatic dispensing device 1000 is disposed at the first position 1000A.

[0481] When the detergent automatic dispensing device 1000 is disposed at the second position 1000B, the storage chamber covers 1140, 1140' can be opened toward the third direction Z.

[0482] Accordingly, when the detergent automatic feeding device 1000 is arranged at the second position 1000B, the user can easily open the first storage chamber lid 1140 and the second storage chamber lid 1140'.

[0483] The storage chamber lids 1140 and 1140' can seal the storage chambers 1200 and 1200' to prevent moisture from penetrating into the storage chambers 1200 and 1200' when the storage chambers 1200 and 1200' are closed.

[0484] The number of the storage chamber lids 1140 and 1140' can be configured to correspond to the number of the storage chambers 1200 and 1200'.

[0485] When the two storage chambers 1200 and 1200' are configured to be opened and closed by one storage chamber lid, the storage chamber lid is configured to cover the two storage chambers 1200 and 1200', which may increase the area of the storage chamber lid. Accordingly, the sealing area of the storage chamber lid increases and the sealing effect of the two storage chambers 1200 and 1200' may be reduced.

[0486] The first storage chamber lid 1140 can be configured to open and close the first storage chamber opening 1121 of the first storage chamber 1200. The second storage chamber lid 1140' can be configured to open and close the second storage chamber opening 1121' of the second storage chamber 1200'.

[0487] The first storage chamber lid 1140 can be configured to seal the first storage chamber opening 1121. The second storage chamber lid 1140' can be configured to seal the second storage chamber opening 1121'.

[0488] As described above, when all of the multiple solid detergents loaded in the first storage chamber 1200 and the second storage chamber 1200' are discharged, the first holder 1500 and the second holder 1500' can be respectively arranged on the lower surfaces 1220 and 1220' of the storage chambers 1200 and 1200'.

[0489] The holder 1500 can move to the lower part of the storage chamber 1200 in the third direction Z by gravity, but cannot move to the upper part of the storage chamber 1200 without external force due to the locking portion 1293. Therefore, the user can hold the handle 1530 of the holder 1500 and move the holder 1500 from one side 1201a of the long side 1201 to the other side 1201b of the long side 1201.

[0490] As an example, both the first storage chamber lid 1140 and the second storage chamber lid 1140' can be 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, either the first storage chamber lid 1140 or the second storage chamber lid 1140' can be opened to load a plurality of solid detergents into either the first storage chamber 1200 or the second storage chamber 1200'.

[0491] Then, as Figure 18 shown, the user can load a plurality of solid detergents into the space between the first lower surface 1220 of the first storage chamber 1200 and the first holding member 1500, and the space between the second lower surface 1220' of the second storage chamber 1200' and the second holding member 1500'.

[0492] Then, the user closes the first storage chamber lid 1140 and the second storage chamber lid 1140' to enclose the storage chambers 1200, 1200', and then moves the door 20 to the closed position 20A. Accordingly, the detergent automatic feeding device 1000 can be set to be arranged at the first position 1000A again, and the holding members 1500, 1500' press the plurality of solid detergents in the third direction Z to continuously maintain the stacked arrangement of the plurality of solid detergents.

[0493] Then, even when the detergent automatic feeding device 1000 is arranged at a position different from the first position 1000A due to the opening of the door 20, the plurality of solid detergents can be held in a stacked arrangement by the holding members 1500, 1500'.

[0494] Hereinafter, for the sake of convenience of description, when describing the storage chamber area 1141, the lid protrusion 1142, and the lid gasket 1144 of the storage chamber lid 1140, the description will be based on one storage chamber 1200, one storage chamber opening 1121, and one storage chamber lid 1140.

[0495] The housing 1100 may include a lid gasket 1144 configured to maintain the seal between the storage chamber lid 1140 and the storage chamber 1200, so that the storage chamber lid 1140 can easily seal the storage chamber 1200.

[0496] As an example, the lid gasket 1144 can be coupled to the storage chamber lid 1140. As an example, the lid gasket 1144 can be coupled to the storage chamber opening edge 1123 that forms the storage chamber opening 1121.

[0497] As an example, the storage chamber lid 1140 may include a lid gasket coupling portion 1143 for coupling the lid gasket 1144.

[0498] The lid gasket joint portion 1143 can be configured to protrude from the inner surface 1140a of the storage chamber lid 1140 in the direction toward the storage chamber 1200 when the storage chamber lid 1140 closes the storage chamber 1200.

[0499] The lid gasket 1144 can be inserted and joined with the lid gasket joint portion 1143 to be joined to the lid gasket joint portion 1143.

[0500] The lid gasket joint portion 1143 is configured to protrude in one direction for the lid gasket 1144 to be inserted and joined, and is formed in the storage chamber lid 1140 in order to reduce the volume of the housing 1100.

[0501] This is because when the lid gasket joint portion 1143 is formed at the storage chamber opening edge 1123, the area of the housing 1100 in the first direction X increases, thereby reducing the area of the tub 12.

[0502] The lid gasket 1144 can be configured to be in close contact with the storage chamber opening edge 1123 to seal the storage chamber opening 1121.

[0503] The storage chamber lid 1140 can include: a storage chamber area 1141, which is located inside the lid gasket 1144 and forms one surface of the storage chamber 1200 when the storage chamber lid 1140 closes the storage chamber opening 1121.

[0504] The storage chamber area 1141 can be configured by an area of the inner surface 1140a of the storage chamber lid 1140.

[0505] As an example, the storage chamber area 1141 can be configured to protrude toward the storage chamber 1200 relative to the inner surface 1140a of the storage chamber lid 1140 when the storage chamber lid 1140 closes the storage chamber opening 1121.

[0506] As an example, considering the size of the cross-sectional area S of the storage chamber 1200 (refer to Figure 7 ), the storage chamber area 1141 can protrude with various lengths.

[0507] As an example, the storage chamber area 1141 can be configured to protrude variably by considering the size of the cross-sectional area S of the storage chamber 1200 (refer to Figure 7 ).

[0508] As an example, the storage chamber area 1141 can protrude in such a way as to ensure the longitudinal length L2 of the appropriate cross-sectional area S of the storage chamber 1200 by considering the longitudinal length d2 of the solid detergent loaded in the storage chamber 1200 (refer to Figure 7 ).

[0509] The storage chamber lid 1140 may include a lid protrusion 1142 configured to protrude from the storage chamber area 1141 toward the storage chamber 1200 when the storage chamber lid 1140 closes the storage chamber opening 1121.

[0510] The lid protrusion 1142 may protrude from one side of the storage chamber area 1141.

[0511] As Figure 19 shown, when the detergent automatic dosing device 1000 is in the first position 1000A, the lid protrusion 1142 may protrude from the lower part of the storage chamber area 1141 toward the storage chamber 1200 in the third direction Z.

[0512] When the detergent automatic dosing device 1000 is in the first position 1000A, the lid protrusion 1142 may protrude obliquely from the storage chamber area 1141 toward the storage chamber 1200 in the third direction Z.

[0513] At this time, the lid protrusion 1142 may be configured to gradually protrude downward in the third direction Z.

[0514] 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 lid protrusion 1142 is not provided in the third direction Z, the longitudinal length L4 of the cross-sectional area S of the storage chamber 1200 set by the lid protrusion 1142 in the internal space of the storage chamber 1200 where the lid protrusion 1142 is provided in the third direction Z is formed shorter.

[0515] The longitudinal length L4 of the cross-sectional area S of the storage chamber 1200 set by the lid protrusion 1142 may be formed to be greater than the longitudinal length d2 of the solid detergent and may be formed to be less than the longitudinal length L2 of the cross-sectional area S of the storage chamber 1200 set by the storage chamber area 1141.

[0516] The longitudinal length of the cross-sectional area S of the storage chamber 1200 may be formed to be shorter at the lower side than at the upper side in the third direction Z.

[0517] When the detergent automatic dosing device 1000 is arranged at the first position 1000A and the lowermost solid detergent among the plurality of solid detergents is dispensed to the outside of the storage chamber 1200, the plurality of solid detergents loaded in the storage chamber 1200 may move downward by gravity.

[0518] Depending on 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, resulting in the collapse of the stacked arrangement of the plurality of solid detergents.

[0519] In particular, when the lowermost solid detergent among multiple solid detergents arranged in the third direction Z is detached from the stacked arrangement, problems may occur because it cannot be discharged to the outside of the storage chamber 1200 by the ejector 1300.

[0520] To prevent this, the lid protrusion 1142 can be arranged at the lower part of the storage chamber area 1141 in the third direction Z to reduce the longitudinal length L4 of the cross-sectional area S at the lower part of the storage chamber 1200 in the third direction Z.

[0521] The lid protrusion 1142 minimizes the gap between the longitudinal length L4 of the cross-sectional area S at the lower part of the storage chamber 1200 in the third direction Z and the longitudinal length ds of the solid detergent, so that the lowermost solid detergent among the solid detergents arranged in the third direction Z moves vertically downward without rotating to one side when moving downward, and thus can be horizontally placed on the lower surface 1220 of the storage chamber 1200.

[0522] As an example, the lid protrusion 1142 is configured to gradually incline from the upper part of the storage chamber area 1141 in the third direction Z, and can be formed such that the protruding length of the lid protrusion 1142 in the lower part of the storage chamber area 1141 in the third direction Z is greater than the protruding length of the lid protrusion 1142 in the upper part.

[0523] Figure 20 FIG. schematically shows a part of the storage chamber and the holder when the detergent automatic feeding device in a dishwasher according to an embodiment is arranged at the second position.

[0524] As an example, the locking portion 1299 can be configured to be recessed in a direction opposite to the direction from the second side 1292 toward the first side 1291.

[0525] The guiding protrusion 1510 can be configured to move to one side 1201a of the long side 1201 by the self-weight of the holder 1500 when the detergent automatic feeding device 1000 is arranged at the first position 1000A.

[0526] As an example, the guiding protrusion 1510 can move downward along the guiding groove 1294 without contacting the first side 1291 and the second side 1292.

[0527] As an example, when the guiding protrusion 1510 moves while being biased toward the first side 1291, the guiding protrusion 1510 can be guided by the first side 1291 and move downward.

[0528] As an example, when the guiding protrusion 1510 moves while being biased toward the second side 1292, the guiding protrusion 1510 can be guided by the second side 1292 and move downward.

[0529] As an example, when the guiding protrusion 1510 moves while being biased toward the second side 1292, the guiding protrusion 1510 may be temporarily inserted into the locking portion 1299, but the guiding protrusion 1510 may move downward from the locking portion 1299 by gravity.

[0530] When the detergent automatic feeding device 1000 is disposed at the first position 1000A, the holding member 1500 may move downward with reference to the third direction Z to press the plurality of solid detergents, thereby maintaining the stacked arrangement of the plurality of solid detergents.

[0531] When the stacking direction of the plurality of solid detergents is oriented in a direction different from the third direction Z by opening the door 20, the holding member 1500 may be configured to support the uppermost solid detergent Dh among the plurality of solid detergents to maintain the stacked arrangement of the plurality of solid detergents.

[0532] When the stacking direction of the plurality of solid detergents is oriented in a direction different from the third direction Z by opening the door 20, the guiding protrusion 1510 may be inserted into the locking portion 1299 to restrict the movement of the guiding protrusion 1510 to the other side 1201b of the long side 1201 due to the movement of the door 20.

[0533] When the door 20 is opened or the door 20 is not disposed at the first position 20A, depending on the situation, an external force may be applied in the direction of the other side 1201b of the long side 1201 by rotation of the door 20 or the like. At this time, the guiding protrusion 1510 may be configured to be inserted into the locking portion 1299 during the movement in the direction of the other side 1201b of the long side 1201 to restrict the movement in the direction of the other side 1201b of the long side 1201, thereby preventing the holding member 1500 from moving in the direction of the other side 1201b of the long side 1201.

[0534] Figure 21 FIG. is a schematic view showing a part of a storage chamber and a holding member when a detergent automatic feeding device in a dishwasher according to an embodiment is disposed at a second position.

[0535] As an example, the guiding protrusion 1510 may include a friction portion 1515 configured to rub against the second side 1292.

[0536] As an example, the friction portion 1515 may be made of a rubber material.

[0537] As an example, the friction portion 1515 may be made of a material different from the material of the holding member 1500.

[0538] When the detergent automatic feeding device 1000 is arranged at the first position 1000A, the guiding protrusion 1510 can be configured to move to one side 1201a of the long side 1201 by the self-weight of the holding member 1500.

[0539] At this time, the friction portion 1515 may rub against the second side 1292, restricting the downward movement. However, due to the self-weight of the holding member 1500, the gravity is greater than the frictional force generated by the friction portion 1515, so that the holding member 1500 can move downward.

[0540] As an example, the guiding protrusion 1510 may move downward along the guiding groove 1294 without contacting the first side 1291 and the second side 1292.

[0541] As an example, when the guiding protrusion 1510 moves while being biased toward the first side 1291, the guiding protrusion 1510 can be guided by the first side 1291 to move downward.

[0542] As an example, when the guiding protrusion 1510 moves while being biased toward the second side 1292, the friction portion 1515 contacts the second side 1292 to generate a frictional force. However, due to gravity, the guiding protrusion 1510 can be guided by the second side 1292 to move downward.

[0543] When the detergent automatic feeding device 1000 is arranged at the first position 1000A, the holding member 1500 can move downward with reference to the third direction Z to press the plurality of solid detergents, thereby maintaining the stacked arrangement of the plurality of solid detergents.

[0544] When the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z due to the opening of the door 20, the holding member 1500 can be configured to support the uppermost solid detergent Dh among the plurality of solid detergents to maintain the stacked arrangement of the plurality of solid detergents.

[0545] When the stacking direction of the plurality of solid detergents faces a direction different from the third direction Z due to the opening of the door 20, the guiding protrusion 1510 may be restricted from moving to the other side 1201b of the long side 1201 along with the movement of the door 20 due to the frictional force generated in the friction portion 1515.

[0546] When the door 20 is opened or the door 20 is not arranged at the first position 20A, depending on the situation, an external force can be applied in the direction of the other side 1201b of the long side 1201 by rotation of the door 20 or the like. At this time, the guiding protrusion 1510 generates a frictional force in the direction opposite to the direction of the other side 1201b of the long side 1201 in the friction portion 1515, and accordingly, the movement in the direction of the other side 1201b of the long side 1201 is restricted, so that the holding member 1500 cannot move in the direction of the other side 1201b of the long side 1201.

[0547] Hereinafter, a storage chamber sensor according to an example will be described.

[0548] Figure 22 FIG. is a view showing a state in which a part of the configuration of a detergent automatic supply device of a dishwasher according to an embodiment is removed, Figure 23 is a view showing Figure 22 a state in which a part of the solid detergent is discharged from the storage chamber, Figure 24 is a view showing Figure 23 a state in which a part of the solid detergent is discharged from the storage chamber, Figure 25 FIG. is a view showing a state in which a part of the configuration of a detergent automatic supply device of a dishwasher according to an embodiment is removed, Figure 26 FIG. is a view showing a state in which a part of the configuration of a detergent automatic supply device of a dishwasher according to an embodiment is removed.

[0549] As an example, the detergent automatic supply device 1000 may include a storage chamber sensor 1270 that senses the inside of the storage chamber 1200. As an example, the storage chamber sensor 1270 may be configured to sense the position of the holding member 1500 in the stacking direction of a plurality of solid detergents.

[0550] The storage chamber sensor 1270 may include a first storage chamber sensor 1270 that senses the inside of the first storage chamber 1200 and a second storage chamber sensor 1245' that senses the inside of the second storage chamber 1200'. The first storage chamber sensor 1270 and the second storage chamber sensor 1245' are both driven in the same manner. Hereinafter, the storage chamber sensor 1270 will be described based on the first storage chamber sensor 1270.

[0551] As an example, the control device 1900 may determine the remaining amount of the solid detergent loaded inside the storage chamber 1200 based on the value sensed by the storage chamber sensor 1270. The control device 1900 may determine the remaining amount of the solid detergent loaded inside the storage chamber 1200 based on the determined position of the holding member 1500.

[0552] As an example, the control device 1900 can communicate with the main control device, and the control unit can control the display unit based on the value judged by the control device 1900 to display the remaining amount of multiple solid detergents inside the storage chamber 1200 on the display unit.

[0553] Assuming that the range within which the holding member 1500 is movable along the stacking direction of the multiple solid detergents inside the storage chamber 1200 is between a first part P1 and a second part P2 inside the storage chamber 1200, the storage chamber sensor 1270 can be configured to be able to sense at which position between the first part P1 and the second part P2 the holding member 1500 is arranged, and can judge the remaining amount of the solid detergents loaded inside the storage chamber 1200 based on this.

[0554] The first part P1 can be defined as the location adjacent to the upper end inside the storage chamber 1200 in the third direction Z when the detergent automatic input device 1000 is arranged at the first position A, and the second part P2 can be defined as the location adjacent to the lower end inside the storage chamber 1200 in the third direction Z when the detergent automatic input device 1000 is arranged at the first position A.

[0555] As an example, when the storage chamber sensor 1270 senses that the holding member 1500 is arranged in the first part P1, the control device 1900 can judge that all the solid detergents that can be loaded are loaded in the storage chamber 1200.

[0556] As an example, as Figure 22 shown, assuming that the storage chamber 1200 can load 9 solid detergents, when the storage chamber sensor 1270 senses that the position of the holding member 1500 is arranged in the first part P1, the control device 1900 can judge that 9 solid detergents are loaded in the storage chamber 1200. Accordingly, the control unit can control the display unit to display on the display unit that 9 solid detergents are loaded into the storage chamber 1200.

[0557] As an example, as Figure 23 shown, when the position of the holding member 1500 is arranged at a certain position between the first part P1 and the second part P2 and the storage chamber sensor 1270 senses the position of the holding member 1500, the control device 1900 can judge the number of solid detergents loaded in the storage chamber 1200 based on the position value of the holding member 1500 arranged corresponding to the number of the loaded solid detergents through the sensed position of the holding member 1500. Accordingly, the control unit can control the display unit to display on the display unit the judged number of solid detergents loaded in the storage chamber 1200.

[0558] As an example, as Figure 24As shown, when the storage chamber sensor 1270 senses that the position of the holder 1500 is the second part P2, the control device 1900 can determine that the number of solid detergents loaded is 1. Accordingly, the control unit can control the display unit to display on the display unit that 1 solid detergent is loaded in the storage chamber 1200.

[0559] When, in a state where the holder 1500 is located in the second part P2, the control unit executes the washing process of the dishwasher 1, the control device 1900 can control the ejector 1300 to cause 1 solid detergent located inside the storage chamber 1200 to separate from the storage chamber 1200. After the storage chamber sensor 1270 senses that the position of the holder 1500 is the second part P2 and after driving the ejector 1300, the control device 1900 can determine that there is no remaining solid detergent inside the storage chamber 1200. Accordingly, the control unit can control the display unit to display on the display unit that there is no solid detergent.

[0560] As an example, the second part P2 can be set to correspond to the lower surface 1220 of the storage chamber 1200. At this time, when the holder 1500 is located in the second part P2, there is a state where there is no solid detergent inside the storage chamber 1200. Therefore, when the storage chamber sensor 1270 senses that the position of the holder 1500 is the second part P2, the control device 1900 can determine that no solid detergent is loaded in the storage chamber 1200.

[0561] The storage chamber sensor 1270 can be configured to be disposed on one of the two side surfaces 1230, 1240 and the inner surface 1260 of the storage chamber 1200. As an example, the storage chamber sensor 1270 can be configured to be disposed on one of the two side surfaces 1230, 1240.

[0562] As an example, the storage chamber sensor 1270 can be configured to sense by magnetism. As an example, the storage chamber sensor 1270 can be configured to be a storage chamber sensor that measures the magnetic flux of the magnet 1501 disposed in the holder 1500. As an example, the storage chamber sensor 1270 can be configured to be a hall sensor. As an example, the storage chamber sensor 1270 can be configured to be a reed switch.

[0563] The holder 1500 can include a magnet 1501 that induces the sensing of the storage chamber sensor 1270. As an example, the magnet 1501 can be disposed on the side of the holder 1500 that faces one of the two side surfaces 1230, 1240 of the storage chamber 1200 where the storage chamber sensor 1270 is disposed.

[0564] As an example, the storage chamber sensor 1270 may be configured with a plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279. The plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279 may be arranged at intervals from each other along the stacking direction of the solid detergent.

[0565] One of the storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279 among the plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279, i.e., the storage chamber sensor 1271, may be arranged at the position where the sensing holder 1500 is located in the first part P1.

[0566] One of the storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279 among the plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279, i.e., the storage chamber sensor 1279, may be arranged at the position where the sensing holder 1500 is located in the second part P2.

[0567] The other storage chamber sensors 1247, 1273, 1274, 1275, 1276, 1277, 1278 among the plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279 may be arranged at intervals from each other along the stacking direction of the solid detergent between the above two storage chamber sensors 1246, 1279.

[0568] The control device 1900 may determine the remaining amount of the solid detergent stored in the storage chamber 1200 based on the values sensed by each of the storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279.

[0569] The plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279 may be respectively arranged at interval distances corresponding to the height of the solid detergent in the stacking direction of the solid detergent. This is for when the solid detergent loaded in the storage chamber 1200 falls out of the storage chamber 1200, the position of the holder 1500 moves a distance equivalent to the height of the solid detergent along the stacking direction of the solid detergent, and the position of the holder 1500 can be clearly grasped by the plurality of storage chamber sensors 1246, 1247, 1273, 1274, 1275, 1276, 1277, 1278, 1279.

[0570] As an example, such as Figure 22As shown, when a certain storage chamber sensor 1271 senses that the position of the holder 1500 is arranged in the first part P1, the control device 1900 can determine that 9 solid detergents are loaded in the storage chamber 1200.

[0571] As an example, as Figure 23 shown, when the position of the holder 1500 is arranged at a certain position between the first part P1 and the second part P2 and a certain storage chamber sensor 1276 senses the position of the holder 1500, the control device 1900 can determine that 4 solid detergents are loaded in the storage chamber 1200.

[0572] As an example, as Figure 24 shown, when a certain storage chamber sensor 1279 senses that the position of the holder 1500 is the second part P2, the control device 1900 can determine that the number of solid detergents loaded is 1.

[0573] As an example, the control device 1900 can determine the remaining amount of solid detergents loaded into the storage chamber 1200 by means of the storage chamber sensor 1270, so the placement part 1400 may not include the placement part sensor 1440.

[0574] As an example, as Figure 25 shown, the storage chamber sensor 1280 can be configured as a light sensor.

[0575] The storage chamber sensor 1280 can include a first storage chamber sensor 1280 that senses the inside of the first storage chamber 1200 and a second storage chamber sensor 1280' that senses the inside of the second storage chamber 1200'. The first storage chamber sensor 1280 and the second storage chamber sensor 1280' are both driven in the same manner. Hereinafter, the storage chamber sensor 1280 will be described based on the first storage chamber sensor 1280.

[0576] The storage chamber sensor 1280 can include: a light emitting part configured to emit light; a light receiving part configured to receive the light emitted from the light emitting part and reflected by the opposite side of the holder 1500 or the storage chamber 1200 or reflected by the solid detergent.

[0577] The storage chamber sensor 1280 can be configured with a plurality of storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289, and each of them is equipped as a light sensor.

[0578] One of the plurality of storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289, such as storage chamber sensor 1281, may be arranged at a position corresponding to the side end of the holder 1500 when the holder 1500 is in the first part P1.

[0579] One of the plurality of storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289, such as storage chamber sensor 1289, may be arranged at a position corresponding to the side end of the holder 1500 when the holder 1500 is in the second part P2.

[0580] The other storage chamber sensors 1282, 1283, 1284, 1285, 1286, 1287, 1288 among the plurality of storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289 may be arranged at intervals from each other along the stacking direction of the solid detergent between the above two storage chamber sensors 1281 and 1289.

[0581] The plurality of storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289 may be respectively arranged at an interval distance corresponding to the height of the solid detergent in the stacking direction of the solid detergent. This is to clearly grasp the position of the holder 1500 through the plurality of storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289 when the position of the holder 1500 moves a distance equivalent to the height of the solid detergent along the stacking direction of the solid detergent when the solid detergent loaded in the storage chamber 1200 comes off to the outside of the storage chamber 1200.

[0582] When the distance sensed in the value sensed by the storage chamber sensor 1280 is greater than a predetermined length, the control device 1900 may judge the position of the holder 1500 based on this.

[0583] As an example, when a value greater than the distance between the storage chamber sensor 1280 and the adjacent side end of the holder 1500 or the adjacent side end of the solid detergent in the second direction Y is sensed, the control device 1900 may judge the position of the holder 1500 based on this.

[0584] As an example, as Figure 25As shown, among the multiple storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289, according to the position of the holder 1500, some of the storage chamber sensors 1281, 1282, 1283, 1284, 1285 can sense the distance between the left surface 1240 and the right surface 1230, and some of the storage chamber sensors 1286, 1287, 1288, 1289 can sense the distance from the left surface 1240 to the side end of the holder 1500 adjacent to the storage chamber sensor 1280 or the side end of the solid detergent adjacent to the storage chamber sensor 1280.

[0585] The control device 1900 can, based on the values sensed by the respective storage chamber sensors 1281, 1282, 1283, 1284, 1285, 1286, 1287, 1288, 1289, determine that the holder 1500 is arranged adjacent to the storage chamber sensor 1286 that starts sensing the distance from the left surface 1240 to the side end of the holder 1500 adjacent to the storage chamber sensor 1280 or to the side end of the solid detergent adjacent to the storage chamber sensor 1280, and can determine the remaining amount of the solid detergent stored in the storage chamber 1200 according to the position of the holder 1500.

[0586] As an example, the control device 1900 can determine the remaining amount of the solid detergent loaded in the storage chamber 1200 by means of the storage chamber sensor 1280, so the placement part 1400 may not include the placement part sensor 1440.

[0587] As an example, as Figure 26 shown, the storage chamber sensor 1280a can be configured as an optical sensor for determining the position of the holder 1500 in the stacking direction of the multiple solid detergents.

[0588] The storage chamber sensor 1280a can include a first storage chamber sensor 1280a for sensing inside the first storage chamber 1200 and a second storage chamber sensor 1280a' for sensing inside the second storage chamber 1200'. The first storage chamber sensor 1280a and the second storage chamber sensor 1280a' are both driven in the same manner, and the storage chamber sensor 1280a will be described below based on the first storage chamber sensor 1280a.

[0589] The storage chamber sensor 1280a can be configured to be arranged on the upper surface 1205 of the storage chamber 1200, and can measure the distance between the holder 1500 and the upper surface 1205 of the storage chamber 1200 in the stacking direction of the multiple solid detergents.

[0590] The storage chamber sensor 1280a may include: a light emitting unit configured to emit light; a light receiving unit configured to receive the light emitted from the light emitting unit and reflected by the holder 1500.

[0591] The storage chamber sensor 1280a may sense the distance of the light reflected from the holder 1500, and the control device 1900 may determine the position of the holder 1500 based on the value sensed by the storage chamber sensor 1280a, and thereby determine the remaining amount of the solid detergent stored in the storage chamber 1200.

[0592] As an example, the control device 1900 may determine the remaining amount of the solid detergent loaded in the storage chamber 1200 by means of the storage chamber sensor 1280a, so the placement unit 1400 may not include the placement sensor 1440.

[0593] Hereinafter, the cross-sectional area of the storage chamber 1200 according to an example will be described in detail.

[0594] Figure 27 FIG. is a view showing a state in which a part of the detergent automatic supply device of the dishwasher according to an embodiment is removed.

[0595] As an example, as Figure 27 shown, the lateral length L1 of the first storage chamber 1200 and the lateral length L5 of the second storage chamber 1200' may be formed to be different from each other.

[0596] As an example, the lateral length L1 of the first storage chamber 1200 may be configured to have a predetermined length so that the above-mentioned solid detergent D can be stored in the storage chamber 1200. The lateral length L5 of the second storage chamber 1200' may be configured to be smaller than the lateral length L1 of the first storage chamber 1200.

[0597] As an example, the lateral length L5 of the second storage chamber 1200' may be configured to be larger than the lateral length L1 of the first storage chamber 1200.

[0598] The width L4 of the placement unit 1400 in the second direction Y may be configured to have a length substantially similar to the width L1 of the first storage chamber 1200. This is because when the width L4 of the placement unit 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 placement unit 1400, it may not be able to be placed on the placement part 1410 and may be in a state of being stuck in the internal space 1401 of the placement unit.

[0599] Conversely, when the width L4 of the placement 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 placement portion 1400 in the second direction Y increases more than necessary, and thus there may be a problem that the volume of the detergent automatic input device 1000 in the second direction Y increases more than necessary.

[0600] Therefore, as described above, preferably, the width L4 of the placement portion 1400 is formed to have a length similar to the width L1 of the first storage chamber 1200 in the second direction Y, where the first storage chamber 1200 has a cross-sectional area S considering the size of the solid detergent.

[0601] If the above-mentioned solid detergent D is defined as a conventional solid detergent D having an appropriate volume for washing considering the capacity of the tub 12 of an ordinary dishwasher 1 and having a predetermined lateral length d1 according to the appropriate volume, then 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 accordingly, the small solid detergent D' can be defined as having a lateral length d1' shorter than the lateral length d1 of the solid detergent D. Alternatively, the small solid detergent D' can be a solid detergent D in a state where the conventional solid detergent D is partially cut in the direction of the lateral length d1.

[0602] In the case where the user only wants to wash a small amount of tableware, generally, it is possible to wash the tableware with an amount less than that of the conventional solid detergent D formed by considering the capacity of the tub 12.

[0603] Different from the conventional solid detergent D stored in the first storage chamber 1200, the second storage chamber 1200' is configured to be able to store a small solid detergent D' having a volume different from that of the solid detergent D, so that the user can selectively wash with the conventional solid detergent D or the small solid detergent D' according to needs.

[0604] The user can input information on the washing mode for the dishwasher 1 through the input unit of the dishwasher 1 or a mobile device, etc., so that the dishwasher 1 selectively performs one of the conventional washing mode or the small amount washing mode.

[0605] The control device 1900 can control the detergent automatic input device 1000 based on the user input obtained from the main control device to drive the first pusher 1300 or the second pusher 1300'.

[0606] When the user selects the conventional washing mode, the control device 1900 can control the detergent automatic input device 1000 to drive the first pusher 1300.

[0607] When the user selects a small amount of washing modes, the control device 1900 can control the detergent automatic input device 1000 to drive the second ejector 1300'.

[0608] The adjusting member 1245 for adjusting the cross-sectional area of the storage chamber 1200 according to an example will be described in detail below.

[0609] Figure 28 FIG. is a view showing a state in which a part of the detergent automatic input device of the dishwasher according to an embodiment is removed. Figure 29 FIG. shows Figure 28 a state in which the adjusting member of the second storage chamber moves.

[0610] As an example, as Figure 28 and Figure 29 shown, the storage chamber 1200 may include an adjusting member 1245 configured to adjust the width inside the storage chamber 1200.

[0611] When the above-mentioned solid detergent D is defined as a conventional solid detergent D having an appropriate volume for washing in consideration of the capacity of the tub 12 of the ordinary dishwasher 1 and having a predetermined lateral length d1 according to the appropriate volume, for a part of the solid detergent D", the capacity can be made smaller than that of the conventional solid detergent D, so that the width d1" of the solid detergent D" is made smaller than the width d1 of the conventional solid detergent D.

[0612] As an example, when a part of the solid detergent D" is stacked in the storage chamber 1200 having a width L1 corresponding to the width d1 of the conventional solid detergent D, inside the storage chamber 1200, due to the gap between the right surface 1230 or the left surface 1240 of the storage chamber 1200 and a part of the solid detergent D", the solid detergent D" moves in the second direction Y, and accordingly, a part of the solid detergent D" detaches from the stacked state of the solid detergent D". When the ejector 1300 is driven in the state where a part of the solid detergent D" has detached, a plurality of solid detergents D" cannot move in the third direction Z by the ejector 1300, so that a part of the solid detergent D" is in a state of being stuck inside the storage chamber 1200, and thus there may be a problem that it cannot be discharged to the outside of the storage chamber 1200.

[0613] As an example, the storage chamber 1200 may include an adjusting member 1245 capable of adjusting the width of the storage chamber 1200 in the second direction Y, and the adjusting member 1245 may move in the second direction Y to adjust the width of the storage chamber 1200.

[0614] Even if the width d1” of a part of the solid detergent D” is formed to be smaller than the width d1 of the conventional solid detergent D, the adjusting member 1245 can adjust the width L6 of the storage chamber 1200 in a manner corresponding to the width d1” of a part of the solid detergent D”, so that the solid detergent D” can be kept in a stacked state inside the storage chamber 1200.

[0615] The adjusting member 1245 may include: a support wall 1246 that supports a plurality of solid detergents; a moving part 1247 connected to the support wall 1246 in the second direction Y to move the support wall 1246 in the second direction and configured to move the position of the support wall 1246 along the second direction Y.

[0616] The adjusting member 1245 may be disposed on the right side surface 1230 or the left side surface 1240 of the storage chamber 1200.

[0617] When the support wall 1246 is disposed closest to the right side surface 1230 or the left side surface 1240, the width L1 of the storage chamber 1200 may be configured to be a length substantially corresponding to the width d1 of the conventional solid detergent D.

[0618] The user can adjust the width of the storage chamber 1200 by pressing the support wall 1246 in the second direction Y. As an example, at a position where the support wall 1246 is adjacent to the right side surface 1230 or the left side surface 1240, the support wall 1246 can be moved along the second direction Y so that the length of the width d1” of a part of the solid detergent D” corresponds to the width L6 of the storage chamber 1200.

[0619] As an example, the moving part 1247 may be configured to extend or contract in the second direction Y so that the support wall 1246 can move along the second direction Y inside the storage chamber 1200.

[0620] As an example, the moving part 1247 may be configured to be able to move along the second direction Y between the outside and the inside of the storage chamber 1200, so that the support wall 1246 can be configured to move along the second direction Y inside the storage chamber 1200.

[0621] As an example, the user can open the storage chamber lid 1140 to open the storage chamber 1200, and can move the adjusting member 1245 along the second direction Y to configure the width of the storage chamber 1200 required by the user. The user can form the width of the storage chamber 1200 required by the user by holding the support wall 1246 and moving the support wall 1246 along the second direction Y to selectively adjust the width of the storage chamber 1200. As the user presses the support wall 1246, the moving part 1247 can extend or contract in the second direction Y.

[0622] As an example, the adjusting member 1245 can be driven by an adjusting member driving device under the control of the control device 1900. The user can input information regarding the width of the storage chamber 1200 into the dishwasher 1 through the input unit of the dishwasher 1 or a mobile device, and the control device 1900 can control the adjusting member 1245 in such a way as to move the moving part 1247 or extend or contract the moving part 1247 based on the user input obtained from the main control device, so that the adjusting member 1245 moves a predetermined distance in the second direction Y.

[0623] The holding member 1500 can be configured to move between the support wall 1246 and the surface 1230 or 1240 of the right side surface 1230 or the left side surface 1240 where the adjusting member 1245 is not arranged.

[0624] As an example, a guide rail 1290 for guiding the movement of the holding member 1500 can be arranged on the support wall 1246. The holding member 1500 can be configured to be guided by the guide rail 1290 arranged on the support wall 1246 and the guide rail 1290 arranged on the surface 1230 or 1240 of the right side surface 1230 or the left side surface 1240 where the adjusting member 1245 is not arranged, and translate in the third direction Z.

[0625] The holding member 1500 can be configured to have a shape that contracts in the second direction Y when the support wall 1246 moves away from the right side surface 1230 or the left side surface 1240.

[0626] The holding member 1500 can be configured to have a shape that contracts or extends in the second direction Y. As an example, the holding member 1500 can be configured to have a telescoping shape, so that it can be folded up and contracted when the support wall 1246 moves towards the center direction of the storage chamber 1200, and can be unfolded and extended when the support wall 1246 moves towards the direction opposite to the center direction of the storage chamber 1200.

[0627] The adjusting member 1245 can include a first adjusting member 1245 arranged inside the first storage chamber 1200 and a second adjusting member 1245' arranged inside the second storage chamber 1200'.

[0628] As an example, the user can adjust the widths of the first storage chamber 1200 and the second storage chamber 1200' by moving each of the first adjusting member 1245 and the second adjusting member 1245'.

[0629] As an example, the user can keep the widths L1 of the first storage chamber 1200 and the second storage chamber 1200' by not moving both the first adjusting member 1245 and the second adjusting member 1245'.

[0630] As an example, the user can adjust the widths of the first storage chamber 1200 and the second storage chamber 1200' by moving only one of the first adjusting member 1245 and the second adjusting member 1245'.

[0631] As an example, the first adjusting member 1245 may be disposed on the left side surface 1240 of the first storage chamber 1200. The second adjusting member 1245' may be disposed on the right side surface 1230' of the second storage chamber 1200'.

[0632] As an example, the second adjusting member 1245' may be disposed on the left side surface 1240' of the second storage chamber 1200'. The first adjusting member 1245 may be disposed on the right side surface 1230 of the first storage chamber 1200.

[0633] As an example, the first adjusting member 1245 and the second adjusting member 1245' may be respectively 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'.

[0634] As an example, the first adjusting member 1245 and the second adjusting member 1245' may be respectively 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'.

[0635] As an example, the adjusting member 1245 may be configured only in one of the first storage chamber 1200 or the second storage chamber 1200'.

[0636] As an example, as Figure 29 shown, the adjusting member 1245 of the first storage chamber 1200 may be configured to be disposed adjacent to the left side 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 member 1245' of the second storage chamber 1200' may be configured to move along the second direction Y from the right side surface 1230' so that the width L6 of the second storage chamber 1200' corresponds to the width d1" of a part of the solid detergent D".

[0637] At this time, the user can load the conventional solid detergent D into the first storage chamber 1200 and can load a part of the solid detergent D" into the second storage chamber 1200'.

[0638] The storage chamber 1200 may include an adjustment member sensing sensor that senses the position of each of the support walls 1246, 1246'. The adjustment member sensing sensor may sense the positions where the support wall 1246 inside the first storage chamber 1200 and the support wall 1246' of the second storage chamber 1200' are arranged, and the control device 1900 may be configured to identify the types of the solid detergents loaded into the first storage chamber 1200 and the solid detergents loaded into the second storage chamber 1200' based on the sensed values.

[0639] As an example, the adjustment member sensing sensor may measure the distance of the position where each of the support walls 1246, 1246' is located, or may sense the distance of the position where each of the support walls 1246, 1246' is located by sensing the length by which each of the moving parts 1247, 1247' moves, extends, or contracts.

[0640] The user may input information on the washing mode for the dishwasher 1 through the input unit of the dishwasher 1 or a mobile device, etc., so that the dishwasher 1 selectively executes one of a normal washing mode and a light washing mode.

[0641] The control device 1900 may control the detergent automatic feeding device 1000 based on the user input obtained from the main control device and the values sensed by the adjustment member sensing sensor to drive the first pusher 1300 or the second pusher 1300'.

[0642] As an example, when the user selects the normal washing mode, the control device 1900 may control the detergent automatic feeding device 1000 to drive the first pusher 1300. When the user selects the light washing mode, the control device 1900 may control the detergent automatic feeding device 1000 to drive the second pusher 1300'.

[0643] As described above, as an example, the holding member 1500 may be configured to move 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. Accordingly, regardless of the direction in which the detergent automatic feeding device 1000 is located, the plurality of solid detergents loaded into the storage chamber 1200 can be kept arranged in the storage chamber by the holding member 1500, so that when the pusher 1300 is driven, the solid detergents can be easily discharged from inside the storage chamber 1200. This is because when the arrangement of the plurality of solid detergents cannot be maintained, the pusher 1300 cannot easily move the solid detergents out of the storage chamber 1200.

[0644] As described above, as an example, when the stacking direction of the plurality of solid detergents is oriented in a direction different from the vertical direction by the opening of the door 20, the holding member 1500 can be configured to support one solid detergent arranged closest to the holding member 1500 among the plurality of solid detergents so as to be able to hold the arrangement of the plurality of solid detergents. When the detergent automatic feeder 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. However, when the stacking direction of the plurality of solid detergents is oriented in a direction different from the vertical direction, it is difficult to maintain the arrangement of the plurality of solid detergents. Therefore, the arrangement of the plurality of solid detergents can be easily maintained by causing the holding member 1500 to support one end of the arrangement of the plurality of solid detergents.

[0645] As described above, as an example, the storage chamber discharge port 1210 and the pusher 1300 can be arranged at the lower part of the storage chamber 1200. Accordingly, the solid detergent located at the lowermost position can be preferentially moved to the outside of the storage chamber 1200. While the solid detergent located at the lowermost position in the direction of gravity is detached, the plurality of solid detergents can move downward while naturally maintaining the arrangement by gravity, so that the arrangement of the plurality of solid detergents can be easily maintained.

[0646] As described above, as an example, the holding member 1500 can be configured to move in the arrangement direction of the plurality of solid detergents from the upper part of the storage chamber 1200. Accordingly, the holding member 1500 is configured to press the plurality of solid detergents in a direction corresponding to the arrangement direction of the plurality of solid detergents by gravity. The plurality of solid detergents are held in arrangement by the pressing of the holding member 1500, and the solid detergent located at the lowermost position among the plurality of solid detergents is pressed against the lower surface 1220 of the storage chamber 1200.

[0647] As described above, as an example, the pusher 1300 is configured to discharge one 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 when the plurality of solid detergents are stored in the detergent automatic feeder 1000, by setting the moving direction of the solid detergent different from the stacking direction of the plurality of solid detergents, the capacity of the detergent automatic feeder 1000 can be thinly set in the first direction X. Accordingly, it can be easily installed in the door 20.

[0648] 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 lowermost position in the vertical direction among the plurality of solid detergents is discharged. Accordingly, the plurality of solid detergents can be sequentially discharged to the outside of the storage chamber 1200 starting from the solid detergent arranged below in the direction of gravity.

[0649] As described above, as an example, the pusher 1300 may be disposed at the lower part of the storage chamber 1200 to move the solid detergent that is the lowest in the vertical direction. Accordingly, the pusher 1300 can easily discharge the solid detergent that is the lowest in the vertical direction among the plurality of solid detergents to the outside of the storage chamber 1200 at the assembled position.

[0650] As described above, as an example, the cam member 1310 is configured to rotate in the first rotation direction with respect to the storage chamber 1200 and can discharge the lowermost solid detergent to the outside of the storage chamber 1200. Accordingly, the pusher 1300 can easily discharge the solid detergent to the outside of the storage chamber 1200 by the self-rotation of the cam member 1310. Therefore, without the movement of physical connection through an additional configuration, the volume of the pusher 1300 can be minimized.

[0651] As described above, as an example, the pressing part 1312a may be configured to rotate in the first rotation direction to press one solid detergent in a direction orthogonal to the stacking direction of the plurality of solid detergents. Accordingly, the pusher 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 detergent automatic feeding device 1000.

[0652] As described above, as an example, the cam member 1310 rotates in the first rotation direction and guides the plurality of solid detergents to move parallel to each other in the stacking direction of the plurality of solid detergents inside the storage chamber 1200. This is because, while the cam member 1310 is configured to press the solid detergent by rotation, during the rotation of the pressing part 1312a and at least a part of the cam member 1310 located inside the storage chamber 1200, the remaining plurality of solid detergents inside the storage chamber 1200 gradually move downward by the rotation of the cam member 1310.

[0653] As described above, as an example, the holder 1500 is configured to move in the vertical direction from the upper part of the storage chamber 1200 in the direction in which the plurality of solid detergents are stacked. Accordingly, when the door 20 is closed, the holder 1500 can fix the plurality of solid detergents in the direction of gravity.

[0654] As described above, as an example, when the direction in which the plurality of solid detergents are stacked faces a direction different from the vertical direction due to the opening of the door 20, the holder 1500 may be configured to support the uppermost solid detergent among the plurality of solid detergents. Accordingly, even if the stacking direction of the plurality of solid detergents is a direction different from the direction of gravity, the holder 1500 can support the stacking of the plurality of solid detergents.

[0655] As described above, as an example, the placement unit 1400 may be disposed on one side of the storage chamber 1200 in a direction orthogonal to the stacking direction of the plurality of solid detergents. Accordingly, the solid detergents moved in a direction orthogonal to the stacking direction of the plurality of solid detergents by the pusher 1300 can be easily placed in the placement unit 1400.

[0656] As described above, as an example, the cam member 1310 is configured to rotate along the direction in which the placement unit 1400 is disposed. Accordingly, the solid detergents moved in a direction orthogonal to the stacking direction of the plurality of solid detergents by the pusher 1300 can be easily placed in the placement unit 1400.

[0657] As described above, as an example, the placement unit opening 1420 may be configured to open in the vertical direction. In addition, the placement unit opening 1420 is formed at the lower end of the internal space of the placement unit 1400 where the solid detergents discharged into the placement unit 1400 are placed. Accordingly, the solid detergents can move in a state of being stacked in the vertical direction in the storage chamber 1200, move in a direction orthogonal to the vertical direction by the pusher 1300, and then move in the vertical direction again in the placement unit 1400, and finally be discharged from the detergent automatic feeding device 1000.

[0658] As described above, as an example, the storage chamber 1200 may include a first storage chamber 1200 disposed on one side of the placement unit 1400 in a direction orthogonal to the stacking direction of the plurality of solid detergents and a second storage chamber 1200' disposed on the other side. Accordingly, the internal space of the detergent automatic feeding device 1000 is effectively arranged, so that the volume of the detergent automatic feeding device 1000 can be minimized.

[0659] Above, specific embodiments have been illustrated and described. However, the present invention is not limited to the above embodiments, and those with ordinary knowledge in the technical field to which the present invention belongs can make various changes and implementations without departing from the gist of the technical concept of the invention described in the claims.
