Description

Technical Field

[0001] The present disclosure relates to a laundry treatment apparatus, and more particularly, to a laundry treatment apparatus including a detergent supply device for supplying detergent. Background Art

[0002] A laundry treatment apparatus is a device that can perform a washing process to remove contaminants from laundry such as clothes, bedding, etc. (hereinafter referred to as laundry) by putting the laundry into a drum. In addition to the washing process, the laundry treatment apparatus can also perform a rinsing process, a dehydration process, a drying process, etc.

[0003] The laundry treatment apparatus may include a cabinet forming an appearance of the apparatus, a tub provided inside the cabinet, and a drum rotatably provided inside the tub and accommodating the laundry therein.

[0004] The laundry treatment apparatus may include a detergent supply device that injects detergent into the tub or the drum to perform a washing process, etc. When the drum rotates while washing water and detergent are supplied to the tub, contaminants can be removed from the laundry due to friction between the laundry and the drum, the washing water, etc.

[0005] The detergent supply device may have a detergent supply function to improve the washing effect. In this regard, the detergent may include any substance that enhances the washing effect, such as a laundry detergent that induces decomposition and removal of contaminants, a fabric softener that improves the flexibility of the laundry fabric, and a bleach that reduces color contamination in the laundry. The detergent may be in powder form and liquid form.

[0006] In one example, Korean Patent Application Publication No. 10-2020-0007549 discloses a laundry treatment apparatus including an existing detergent supply device. The existing detergent supply device includes a drawer that can protrude from the cabinet and a detergent flow passage defined in the drawer to guide the detergent to the tub. The above-mentioned existing manual detergent supply device is a scheme of supplying the detergent introduced into the detergent passage to the tub together with water.

[0007] However, in the above-mentioned existing manual detergent supply device, the user directly injects the detergent during each washing process. Therefore, it is difficult to perform quantitative injection, and it is not convenient for the user to inject the detergent each time.

[0008] To solve this problem, a detergent supply device that automatically supplies detergent for each washing process has been developed. In addition, a scheme has been developed to add the above-mentioned automatic detergent supply device to a laundry treatment apparatus equipped with an existing manual detergent supply device to allow the user to select either detergent supply device.

[0009] When additionally installing an automatic detergent supply device as described above, it is necessary to ensure space for each component of the automatic detergent supply device to be installed. However, a laundry treatment apparatus equipped with a manual detergent supply device and other components may have limitations in the space where the automatic detergent supply device is to be installed. To overcome this problem, a structure in which a part of the automatic detergent supply device is placed outside the cabinet has been developed.

[0010] Korean Patent Application Publication No. 10-2020-0120202 discloses a laundry treatment apparatus in which a storage tank for storing detergent for the automatic detergent supply device is provided outside the cabinet.

[0011] When the manual detergent supply device and the automatic detergent supply device are provided together in the laundry treatment apparatus, the detergent for the automatic detergent supply device can be delivered to the manual detergent supply device, and the detergent for the manual detergent supply device and the detergent for the automatic detergent supply device can be discharged together into the tub.

[0012] However, when the detergent for the automatic detergent supply device is supplied into the manual detergent supply device, the detergent for the automatic detergent supply device may scatter inside the manual detergent supply device even when there is no detergent for the manual detergent supply device and only the detergent for the automatic detergent supply device is used. In addition, considering hygiene and the like, there may be a problem of cleaning the detergent for the automatic detergent supply device in the area where the detergent for the automatic detergent supply device is dispensed.

[0013] Even when water is supplied to the manual detergent supply device, the detergent for the automatic detergent supply device may be dispensed and remain in an area where water cleaning is not smooth because the detergent for the automatic detergent supply device scatters and the like during the inflow process of the detergent for the automatic detergent supply device. In this case, hygiene may be a problem due to poor cleaning.

[0014] In one example, in the case of an automatic detergent supply device that automatically supplies detergent, sensors can be provided to identify the remaining amount of the detergent for the automatic detergent supply device and whether the detergent for the automatic detergent supply device is normally supplied. Similar to the above-described laundry treatment apparatus, the sensors can be provided in the storage tank storing the detergent for the automatic detergent supply device to sense the detergent for the automatic detergent supply device.

[0015] However, in the above-described laundry treatment apparatus, a storage tank storing detergent for an automatic detergent supply device is provided outside the cabinet, such that terminals connected to sensors and the like may be exposed to the outside, thereby being liable to contamination or damage, which may cause malfunctions or failures of the sensors.

[0016] Therefore, in a case where at least a part of the automatic detergent supply device is exposed to the outside of the cabinet, it is an important task in the technical field to develop a structure in which a sensor for sensing detergent for the automatic detergent supply device is stably held and can effectively sense the detergent for the automatic detergent supply device.

[0104] Figure 1 The appearance of a laundry treating apparatus according to an embodiment of the present disclosure is shown, and Figure 2 is shown Figure 1 in a state in which the door 110 is opened in the laundry treating apparatus.

[0105] Referring to Figure 1 and Figure 2 , a laundry treating apparatus according to an embodiment of the present disclosure includes a cabinet 10. The cabinet 10 may have a space defined therein and may be generally formed in the shape of a column.

[0106] The cabinet 10 may include a cabinet body 15 and a top cover 100 having a laundry inlet 101 defined therein. The cabinet body 15 may define a space therein in which a tub 20, a drum 30, etc. are provided, and has an open top surface.

[0107] The cabinet body 15 may include a plurality of panels such as a front panel, a rear panel, side panels, etc. and a base or bottom panel constituting its bottom, and at least two panels may be integrally formed.

[0108] The top cover 100 can form the top surface of the cabinet 10. At least a part of the top cover 100 can be opened to define a clothing inlet 101 for introducing clothing into the cabinet 10. The top cover 100 can include a cover space 140 which will be described later, and the cover space 140 can correspond to a part of the internal space of the cabinet 10.

[0109] In one embodiment of the present disclosure, the top cover 100 can have a door 110. The door 110 can be pivotable so as to cover the clothing inlet 101. That is to say, the door 110 can be arranged to open and close the clothing inlet 101.

[0110] The cabinet 10 can have a control panel 50. The control panel 50 can include an output unit for providing information to the user and an input unit manipulated by the user to generate an input signal.

[0111] In one embodiment of the present disclosure, the top cover 100 can include a front portion 120 located in front of the door 110 and a rear portion 130 located at the rear of the door 110. The control panel 50 can be provided on the front portion 120.

[0112] In one example, in one embodiment of the present disclosure, a first reservoir 200 can be provided on the rear portion 130 of the top cover 100. The first reservoir 200 can store a first detergent therein and can supply the first detergent to the tub 20 when a washing process of clothing etc. is executed.

[0113] At least a part of the first reservoir 200 can be exposed to the outside of the cabinet 10. Figure 1 The state where the reservoir body 210 protrudes upward from the top cover 100 is shown, in which the first detergent is stored in the first reservoir 200.

[0114] In the present disclosure, the interior of the cabinet 10 can be defined as an area not exposed to the outside of the cabinet 10. For example, the cover space 140 defined within the top cover 100 is not exposed to the outside of the cabinet 10 and can be understood as a part of the internal space of the cabinet 10.

[0115] The reservoir body 210 can be exposed to the outside at the rear portion 130 of the top cover 100. The reservoir body 210 can protrude upward from the rear portion 130 of the top cover 100 and can be detached from the cabinet 10.

[0116] While the reservoir body 210 is connected to the cabinet 10, the user can store the first detergent in the reservoir body 210, or remove the reservoir body 210 from the cabinet 10 to store the first detergent or clean the reservoir body 210.

[0117] Figure 3 is a cross-sectional view showing the interior of a laundry treating apparatus according to an embodiment of the present disclosure.

[0118] Referring to Figure 3 , a tub 20 and a drum 30 may be disposed inside the cabinet 10. The tub 20 may receive water therein and include a tub inlet 22 that opens toward a laundry inlet 101.

[0119] In one embodiment of the present disclosure, the laundry inlet 101 may be located in the top cover 100, and the tub inlet 22 of the tub 20 may also open upward. That is, the laundry treating apparatus according to one embodiment of the present disclosure may be a top-loading type with its axis perpendicular to the ground.

[0120] The drum 30 may be disposed inside the tub 20. The drum 30 may be rotatably mounted inside the tub 20 and may receive laundry therein. The drum 30 may include a drum inlet 32 that opens toward the laundry inlet 101.

[0121] Accordingly, the laundry input toward the laundry inlet 101 may pass through the tub inlet 22 and the drum inlet 32 and be received inside the drum 30. The tub 20 and the drum 30 may have a cylindrical shape with a space defined therein, and a plurality of communication holes 31 may be defined in the circumferential surface of the drum 30.

[0122] When water is stored inside the tub 20, the drum 30 may share the water with the tub 20 by allowing the water in the tub 20 to flow into it through the communication holes 31.

[0123] In one example, in one embodiment of the present disclosure, a first reservoir 200 and a second reservoir 300 may be disposed at an upper portion of the cabinet 10. The top cover 100 may have a cover space 140 defined inside a rear portion 130 located at the rear of the door 110.

[0124] The top cover 100 may be opened to upwardly expose the cover space 140, and the first reservoir 200 may include a mounting portion 240 configured to cover the open surface of the cover space 140. The first reservoir 200 may include a reservoir body 210 in which a first detergent is stored, and the reservoir body 210 may be mounted on the mounting portion 240 on the top cover 100.

[0125] The second reservoir 300 may be located in the cover space 140. The first detergent in the first reservoir 200 may be supplied to the second reservoir 300. The second reservoir 300 may accommodate a second detergent therein, and the first detergent and the second detergent may be discharged together toward the tub 20.

[0126] Additionally, an embodiment of the present disclosure may include a water supply device 600 connected to a water supply source outside the cabinet 10, and the second reservoir 300 may receive water from the water supply device 600. Accordingly, the first detergent and the second detergent may be mixed with water in the second reservoir 300 and then discharged into the tub 20.

[0127] An embodiment of the present disclosure includes a drive 40. The drive 40 may be located below the tub 20 and may be connected to the drum 30 via a drive shaft extending through the tub 20. In other words, the drum 30 may receive a rotational force from the drive 40 via the drive shaft inside the tub 20.

[0128] A rotor 35 may be provided on the bottom of the drum 30. The rotor 35 may cover at least a portion of the bottom surface of the drum 30 from above and may rotate with the drum 30 or independently of the drum 30.

[0129] The rotor 35 may be connected to the drive 40. The drive 40 may include a transmission or the like, and the drive shaft may include a solid shaft and a hollow shaft connected to the transmission. One of the solid shaft and the hollow shaft may be connected to the drum 30, and the other may be connected to the rotor 35.

[0130] In one example, a suspension 25 that supports the tub 20 to the cabinet 10 may be provided inside the cabinet 10. The suspension 25 may include an elastomer or the like and may reduce vibrations transmitted from the tub 20.

[0131] Accordingly, vibrations generated from the drum 30 or the drive 40 and transmitted through the tub 20 are attenuated by the suspension 25, so that the amount of vibrations transmitted to the cabinet 10 can be reduced.

[0132] Additionally, a drainage device 700 may be connected to the tub 20. As the washing process proceeds, the washing water containing contaminants may be discharged from the tub 20 to the outside of the cabinet 10 via the drainage device 700.

[0133] In one example, Figure 4 a reservoir body 210 attached to or detachable from the cabinet 10 along the height direction Z of the cabinet 10 in an embodiment of the present disclosure is shown, and Figure 5 a reservoir body 210 attached to or detachable from the cabinet 10 along the width direction Y of the cabinet 10 in an embodiment of the present disclosure is shown.

[0134] Specifically, in an embodiment of the present disclosure, the reservoir body 210 of the first reservoir 200 may be removed from the cabinet 10. The mounting portion 240 of the first reservoir 200 may be fixed to the top cover 100, and the reservoir body 210 may be attached to or detached from the mounting portion 240.

[0135] There can be various attachment / detachment schemes for the memory body 210, and there can also be various attachment / detachment directions. For example, the memory body 210 can be removed from the cabinet 10 or coupled to the cabinet 10 along the height direction Z of the cabinet 10.

[0136] Additionally, the memory body 210 can be removed from the cabinet 10 or coupled to the cabinet 10 along the width direction Y of the cabinet 10. When the memory body 210 is attached or detached along the width direction Y, the first memory body 211 can be coupled to the cabinet 10, i.e., the mounting portion 240, at one side in the width direction Y of the cabinet 10, and the second memory body 212 can be coupled to the mounting portion 240 at the other side in the width direction Y.

[0137] In one embodiment of the present disclosure, in a user's living environment, walls of a building or the like can be located on both sides of the cabinet 10. Thus, the memory body 210 can be coupled to the cabinet 10 in the vertical direction, such that the memory body 210 can be effectively coupled to the cabinet 10 even when the space is restricted on both sides.

[0138] Furthermore, even when the memory body 210 is coupled along the width direction Y of the cabinet 10, it can be designed such that the total width of the memory body 210 coupled to the cabinet 10 is smaller than the total width of the cabinet 10.

[0139] Additionally, the moving distance in the width direction Y required for the coupling and removal of the memory body 210 can be limited within the entire width of the cabinet 10. That is, in one embodiment of the present disclosure, the memory body 210 can move within the width of the cabinet 10 to be coupled to the cabinet 10 or removed from the cabinet 10, such that the space can be effectively utilized.

[0140] In one example, Figure 6 a memory body 210 according to an embodiment of the present disclosure is shown, and Figure 7 the memory body 210 with the memory cap 214 in an open state is shown. The memory body 210 can include a space defined therein for storing a first detergent. The memory body 210 can be exposed to the outside of the cabinet 10, and a detergent injection hole 216 for introducing the detergent can be defined in the memory body 210.

[0141] The memory body 210 can include a memory body main body 213 and a memory cap 214. The memory body main body 213 can include a space defined therein for storing a first detergent, can include a detergent injection hole 216 defined therein, and can form at least a part of the appearance of the memory body 210.

[0142] The reservoir cap 214 may be pivotally provided on the reservoir body 213. The reservoir cap 214 may close or open the detergent injection hole 216. The reservoir cap 214 may form a part of the appearance of the reservoir body 210.

[0143] The reservoir body 210 may include an exterior 215. The exterior 215 may be provided on the reservoir body 213 to form a part of the appearance of the reservoir body 210. The exterior 215 and the reservoir cap 214 may be provided together on one surface of the reservoir body 213. In other words, the exterior 215 and the reservoir cap 214 may together form one surface of the reservoir body 210 and enhance the integrity of the appearance of the reservoir body 210.

[0144] In one example, Figure 8 is a bottom view of the reservoir body 210. The reservoir body 213 may include a reservoir bottom 220 that forms the bottom surface of the reservoir body 210. The reservoir bottom 220 may be located on the mounting portion 240 and may be supported by the mounting portion 240.

[0145] The detergent valve 225 may be provided on the reservoir bottom 220. The detergent valve 225 may be in an open or closed state. The detergent valve 225 may allow the interior and exterior of the reservoir body 213 to communicate with each other in the open state. When the reservoir body 210 is attached or detached along the width direction Y of the cabinet 10, the detergent valve 225 may have a longitudinal direction substantially parallel to the width direction Y.

[0146] A bottom inclined portion 221 that is inclined toward the detergent valve 225 may be formed at least in part of the reservoir bottom 220. The bottom inclined portion 221 may be formed to incline downward and may form at least a part of the reservoir bottom 220.

[0147] Due to the bottom inclined portion 221, the detergent valve 225 may be located at the lowermost end of the reservoir bottom 220. The bottom inclined portion 221 may incline closer to the ground in the direction toward the center of the cabinet 10 along the width direction Y of the cabinet 10.

[0148] In one example, the reservoir bottom 220 may include a bottom damper 223 that protrudes downward toward the mounting portion 240. The bottom damper 223 may be made of a high-friction material such as rubber or may be a highly elastic body.

[0149] The bottom damper 223 may support the reservoir body 210 from the mounting portion 240 and eliminate the gap between the reservoir body 210 and the mounting portion 240.

[0150] The bottom 220 of the reservoir may have variable protrusions 217. The variable protrusions 217 may protrude downward from the bottom 220 of the reservoir, and the amount of protrusion thereof may vary.

[0151] For example, the reservoir body 210 may have a variable button 218 that is at least partially exposed to the outside, and the position of the variable protrusion 217 may vary in association with the variable button 218. The user can change the degree of protrusion of the variable protrusion 217 by manipulating the variable button 218.

[0152] It can be determined whether the reservoir body 210 can be attached to the cabinet 10 or the mounting portion 240 or detached from the cabinet 10 or the mounting portion 240 according to the amount of protrusion of the variable protrusion 217. For example, the variable protrusion 217 may be inserted into the reservoir body 210 or may protrude to the outside. When the variable protrusion 217 is in a protruding state, the reservoir body 210 cannot be mounted on the cabinet 10 or removed from the cabinet 10. However, when the variable protrusion 217 is inserted into the reservoir body 210, the reservoir body 210 can be mounted on the cabinet 10 or removed from the cabinet 10.

[0153] The reservoir body 210 may include a bottom side wall 222. The bottom side wall 222 may extend along the perimeter of the bottom 220 of the reservoir and may protrude toward the mounting portion 240. The bottom side wall 222 may be provided at the front and rear ends of the bottom 220 of the reservoir. At least a part of the bottom 220 of the reservoir (e.g., the detergent valve 225) may be invisible from the outside at the front and rear parts through the bottom side wall 222.

[0154] Figure 9 An exploded perspective view of the first reservoir 200 is shown. Referring to Figure 9 , each component of the first reservoir 200 will be described as follows.

[0155] The first reservoir 200 may include a reservoir body 210 and a mounting portion 240. The reservoir body 210 may be exposed to the outside of the cabinet 10 and may store the first detergent therein. The mounting portion 240 may be fixed to the cabinet 10 and may form a part of the cabinet 10.

[0156] The reservoir body 210 may include a reservoir main body 213, and a space for storing the first detergent is defined inside the reservoir main body 213. The reservoir main body 213 may include a detergent injection hole 216 that allows the inside and the outside to communicate with each other.

[0157] The detergent injection hole 216 may be defined in the top surface of the reservoir body 213 and may be opened and closed by a reservoir cap 214 coupled to the reservoir body 213. The exterior 215 may be provided in an area of the top surface of the reservoir body 213 other than the reservoir cap 214, and the exterior 215 and the reservoir cap 214 may together form one surface of the reservoir body 210.

[0158] The reservoir bottom 220 may be provided at the bottom of the reservoir body 213. The reservoir bottom 220 may be manufactured separately from the reservoir body 213 and provided to cover the open bottom surface of the reservoir body 213, or may be molded together with the reservoir body 213 and correspond to a part of the reservoir body 213.

[0159] The variable protrusion 217 may be provided inside the reservoir body 213 or inside the reservoir bottom 220. The variable protrusion 217 may protrude downward from the reservoir bottom 220. The amount by which the variable protrusion 217 protrudes downward from the reservoir bottom 220 may vary.

[0160] The reservoir body 213 may have a variable button 218 connected to the variable protrusion 217. The position of the variable protrusion 217 may change according to the operating state of the variable button 218. The user may manipulate the variable button 218 to be in a first state such that the variable protrusion 217 is located inside the reservoir bottom 220. When the user manipulates the variable button 218 to be in a second state, the position of the variable protrusion 217 may change to protrude downward from the reservoir bottom 220.

[0161] The mounting portion 240 may be located below the reservoir bottom 220. The mounting portion 240 may include a placement surface 252 on which a bottom inclined portion 221 of the reservoir bottom 220 is placed. The placement surface 252 may have an inclined shape to correspond to the bottom inclined portion 221.

[0162] The mounting portion 240 may include a fastening tube 242, and the fastening tube 242 may extend through the placement surface 252 and a part of the fastening tube 242 may be provided on the placement surface 252. The fastening tube 242 may be inserted into the detergent valve 225 of the reservoir body 210. The detergent valve 225 may open when the fastening tube 242 is inserted therein and may close when the fastening tube 242 is removed therefrom.

[0163] Figure 10 The appearance of the mounting portion 240 of the first reservoir 200 is shown. The mounting portion 240 may form the top surface of the rear portion 130 of the top cover 100 to which the reservoir body 210 may be coupled.

[0164] When the memory body 210 is coupled to the mounting portion 240 along the width direction Y of the cabinet 10, the fastening pipe 242 can extend along the width direction Y of the cabinet 10 on the placement surface 252. Therefore, the fastening pipe 242 can be inserted into the detergent valve 225 that is attached and detached along the width direction Y of the memory body 210.

[0165] The upwardly protruding central portion 241 can be disposed at the center of the mounting portion 240 based on the width direction Y. That is, the central portion 241 can have a shape that protrudes upward from the placement surface 252. The memory body 210 can include a plurality of memory bodies, and can include a first memory body 211 and a second memory body 212.

[0166] The first memory body 211 and the second memory body 212 can move from both sides of the central portion 241 toward the central portion 241 and be mounted on the mounting portion 240. A part of the memory bottom 220 of the memory body 210 can be located on the central portion 241 and be supported by the central portion 241. The fastening pipe 242 can extend through the central portion 241 in the width direction Y of the cabinet 10.

[0167] The mounting portion 240 can include a protruding portion 250 that protrudes upward around the placement surface 252. The mounting portion 240 can include a stepped portion 253 that is stepped outward from the periphery of the protruding portion 250. In other words, the placement surface 252 can have a shape that is recessed downward from the top surface of the protruding portion 250 in the mounting portion 240.

[0168] Figure 11 The hook groove 254 of the mounting portion 240 is shown. The hook groove 254 can be located on the side opposite to the central portion 241 around the placement surface 252. That is, the hook groove 254 can be defined at each of the two ends of the mounting portion 240 in the width direction Y.

[0169] Specifically, the mounting portion 240 can include a protruding portion 250 that protrudes upward such that its periphery is stepped, and the top surface of the protruding portion 250 can be recessed downward to form the placement surface 252 on which the memory bottom 220 of the memory body 210 is placed.

[0170] Based on the width direction Y of the cabinet 10, the central portion 241 can be located at one end of the placement surface 252, and the protruding support surface 255 can be located at the other end of the placement surface 252. The protruding support surface 255 can correspond to the stepped surface formed between the placement surface 252 and the topmost surface of the protruding portion 250.

[0171] The above-mentioned hook groove 254 may be located outside the protruding portion 250 in the width direction Y. The fastening hook provided on the storage body 210 may be inserted into the hook groove 254.

[0172] The above-mentioned stepped portion 253 may be formed around the protruding portion 250. The stepped portion 253 may include a stepped surface that is located below the topmost surface of the protruding portion 250 and outside the periphery of the protruding portion 250. That is, the protruding portion 250 may be formed such that its topmost surface and the stepped surface are stepped with each other.

[0173] The stepped portion 253 may be defined at least at the front end and the rear end of the periphery of the protruding portion 250. The bottom side wall 222 of the storage body 210 may be arranged to slide on the stepped portion 253 in the width direction Y of the cabinet 10. That is, the bottom side wall 222 may be located on and slide on the stepped surface of the stepped portion 253 and may be supported by the stepped surface.

[0174] In one example, referring to Figure 10 and Figure 11 , the fastening structure of the storage body 210 to the mounting portion 240 will be described in detail as follows.

[0175] First, in the process of reinstalling the storage body 210 removed from the cabinet 10 back into the cabinet 10, the storage body 210 may be located on the mounting portion 240 and move in the width direction Y of the cabinet 10. In this process, the bottom inclined portion 221 of the storage body 210 may be positioned on the placement surface 252 of the mounting portion 240.

[0176] The movement of the storage body 210 in the width direction Y may be restricted by the central portion 241 of the mounting portion 240 that protrudes beyond the placement surface 252. Additionally, the bottom inclined portion 221 of the storage body 210 may be supported on the placement surface 252, thereby restricting its movement towards the ground.

[0177] In one example, the storage body 210 may be installed in a state where the variable button 218 is manipulated and the variable protrusion 217 is inserted into the storage body 210, and the installation process may end when the variable protrusion 217 protrudes downward from the storage bottom 220 again from the installation position.

[0178] The variable protrusion 217 protruding downward from the storage bottom 220 may have a protrusion support surface 255 located on one side in the lateral direction of the cabinet 10. Due to the contact relationship between the protrusion support surface 255 and the variable protrusion 217, the movement of the storage body 210 towards one side in the lateral direction of the cabinet 10 may be restricted.

[0179] In one example, the hook groove 254 described above may be located on a side of the protruding portion 250 of the mounting portion 240 opposite to the central portion 241, and the hook groove 254 may have a shape recessed along the width direction Y.

[0180] During the installation process of the memory body 210, the fastening hook of the memory body 210 may be inserted into the hook groove 254 of the protruding portion 250 along the width direction Y. When the fastening hook is inserted into the hook groove 254, upward movement of the memory body 210 may be restricted.

[0181] Additionally, during the installation process of the memory body 210, the bottom side wall 222 of the memory body 210 may slide along the step portion 253 of the mounting portion 240, so that the bottom side wall 222 may be disposed in front of and behind the protruding portion 250, respectively. Based on the structural relationship in which the protruding portion 250 is located between the bottom side walls 222 (which are located at the front and rear sides of the memory body 210), movement of the memory body 210 in the front-rear direction X may be restricted.

[0182] That is, during the installation process onto the mounting portion 240, movement of the memory body 210 in the front-rear direction X, width direction Y, and height direction Z of the cabinet 10 may be completely restricted, so that the memory body 210 may be stably fixed.

[0183] In one example, Figure 12 A state is shown in which the memory body 210 of the first memory 200 and the mounting portion 240 are removed from the top cover 100, and thus the cover space 140 of the top cover 100 is exposed to the outside.

[0184] The rear portion 130 of the top cover 100 may be located behind the door 110 and the clothing inlet 101. The cover space 140 may be defined inside the rear portion 130. The top cover 100 may have a cover space 140 with an open top surface. When the mounting portion 240 is coupled to the open top surface of the cover space 140, the cover space 140 may be closed, and at the same time, the mounting portion 240 may form a part of the top cover 100.

[0185] The first memory 200 may be disposed on the cover space 140, and the second memory 300 may be disposed inside the cover space 140. In addition to the second memory 300, a detergent pump 400 or the like for allowing the first detergent in the first memory 200 to flow may be installed inside the cover space 140.

[0186] The top cover 100 may include the above-mentioned laundry inlet 101 defined therein. The top cover 100 may include a laundry inlet outer peripheral surface 102 around the laundry inlet 101. The laundry inlet outer peripheral surface 102 may be recessed into the cabinet 10.

[0187] The second reservoir 300 may include a drawer 340 that can extend out of the lid space 140. The drawer 340 may extend through the laundry inlet outer peripheral surface 102 and be exposed to the laundry inlet 101, and may extend out via the laundry inlet 101. In addition to the second reservoir 300, connecting pipes connected to the fastening pipe 242, the water supply device 600, etc. may be provided in the lid space 140.

[0188] In one example, Figure 13 the second reservoir 300 connected to the first reservoir 200 is shown, and Figure 14 shown Figure 13 the disassembled first reservoir 200 and second reservoir 300 in

[0189] Referring to Figure 13 and Figure 14 , the second reservoir 300 provided in the lid space 140 may be located below the first reservoir 200. For example, the second reservoir 300 may be located below the reservoir body 210 and the mounting portion 240.

[0190] The first reservoir 200 located on the lid space 140 may be at least partially exposed to the outside of the cabinet 10 to store the first detergent therein, and the second reservoir 300 may be provided inside the cabinet 10, may accommodate the second detergent therein, and may communicate with the tub 20. The interior of the cabinet 10 may be defined to include the lid space 140.

[0191] The second reservoir 300 may extend from the lid space 140 through the above-mentioned laundry inlet outer peripheral surface 102 and communicate with the laundry inlet 101. Accordingly, the second reservoir 300 may communicate with the interior of the tub 20 via the laundry inlet 101.

[0192] The second reservoir 300 may include a receiving housing 310 provided in the lid space 140 and communicating with the laundry inlet 101 via the laundry inlet outer peripheral surface 102, and a space for accommodating the drawer 340 may be defined in the receiving housing 310.

[0193] One surface of the receiving housing 310 facing the laundry inlet 101 may be open to define an open surface of the housing. In the laundry inlet outer peripheral surface 102, a region corresponding to the open surface of the housing may be open such that the interior of the receiving housing 310 and the laundry inlet 101 can communicate with each other, and the drawer 340 can be retracted into the receiving housing 310 via the open surface of the housing.

[0194] A part of the open surface of the housing can define a detergent outflow area through which the second detergent etc. flows out. For example, the lower area of the open surface of the housing can define a detergent outflow area for the second detergent received in the housing 310 to flow out toward the laundry inlet 101.

[0195] One embodiment of the present disclosure may include a detergent pump 400. The detergent pump 400 may be disposed inside the cabinet 10. For example, the detergent pump 400 may be installed in the cover space 140. The detergent pump 400 may be connected to the first reservoir 200 and may allow the first detergent to flow. In one embodiment of the present disclosure, the first reservoir 200 may correspond to an automatic detergent supply device connected to the detergent pump 400, and the first detergent is provided to the tub 20 from the automatic detergent supply device during washing by automatic flow.

[0196] The detergent pump 400 may include a plurality of detergent pumps. As described above, the reservoir body 210 of the first reservoir 200 may include a first reservoir body 211 and a second reservoir body 212, and the detergent pump 400 may include a first detergent pump 401 connected to the first reservoir body 211 and a second detergent pump 402 connected to the second reservoir body 212.

[0197] The detergent valve 225 of the reservoir body 210 may be coupled to the fastening pipe 242 of the mounting portion 240. The fastening pipe 242 may be connected to the detergent pump 400 via an outflow pipe 410 for the first detergent to flow, and the detergent pump 400 may be connected to the second reservoir 300 via a detergent pipe 420.

[0198] The second reservoir 300 may include a detergent connection port 321 to which the detergent pipe 420 is connected. The detergent connection port 321 may have a connection portion 325, which can increase the rigidity of the detergent connection port 321 and strengthen the connection between the detergent pipe 420 and the detergent connection port 321.

[0199] The connection portion 325 can serve as a check valve, and thus, can prevent the fluid that may contain the first detergent, the second detergent, and water from flowing back from the second reservoir 300 to the detergent pump 400 via the detergent pipe 420.

[0200] The receiving housing 310 of the second reservoir 300 may include a water connection port 322 to which a water supply pipe 620 is connected, and the water supply pipe 620 connected to an external water supply source may be connected to the water connection port 322, so that water can be supplied into the second reservoir 300.

[0201] In one embodiment of the present disclosure, the flow processes of the first detergent, the second detergent, and water will be described based on each component as follows.

[0202] First, the first detergent can be stored inside the reservoir body 210 of the first reservoir 200, and the reservoir body 210 can have a detergent valve 225 that selectively allows the interior and exterior to communicate with each other. The detergent valve 225 can be substantially in a closed state to prevent the first detergent in the reservoir body 210 from leaking.

[0203] In the process of connecting the reservoir body 210 to the mounting portion 240 provided on the cabinet 10, at least a part of the fastening pipe 242 provided in the mounting portion 240 can be inserted into or connected to the detergent valve 225. The detergent valve 225 can switch to an open state when the fastening pipe 242 is inserted into it.

[0204] That is to say, when the reservoir body 210 is connected to the mounting portion 240, the fastening pipe 242 of the mounting portion 240 can be inserted into the detergent valve 225 and communicate with the interior of the reservoir body 210. One end of the fastening pipe 242 can be inserted into the detergent valve 225, and the other end of the fastening pipe 242 can extend through the mounting portion 240 and be positioned in the cover space 140.

[0205] The other end of the fastening pipe 242 can be connected to the outflow pipe 410. The outflow pipe 410 can be provided in the cover space 140. One end of the outflow pipe 410 can be connected to the fastening pipe 242, and the other end thereof can be connected to the detergent pump 400 located in the cover space 140.

[0206] Therefore, the first detergent flowing out from the reservoir body 210 via the detergent valve 225 can be supplied to the detergent pump 400 through the fastening pipe 242 and the outflow pipe 410. This flow of the first detergent can be generated by the detergent pump 400.

[0207] The detergent pump 400 can be located below the first reservoir 200, connected to the reservoir body 210 via the outflow pipe 410, and can be controlled by a controller or the like in a case where the first detergent needs to flow (for example, during the washing process), and can allow the first detergent to flow.

[0208] The detergent pump 400 can be connected to the second reservoir 300 via the detergent pipe 420 and allow the first detergent to flow into the second reservoir 300. One end of the detergent pipe 420 can be connected to the detergent pump 400, and the other end thereof can be connected to the second reservoir 300.

[0209] The detergent pump 400 can be fixed at various positions. The detergent pump 400 can be disposed inside the lid space 140 and can be located in the width direction Y of the cabinet 10 with respect to the second reservoir 300.

[0210] In one embodiment of the present disclosure, the plurality of reservoir bodies 210 may include a first reservoir body 211 and a second reservoir body 212, and the outflow pipe 410 and the detergent pipe 420 may respectively include a pair of outflow pipes and a pair of detergent pipes corresponding thereto. In addition, the detergent pump 400 may further include a plurality of detergent pumps and include a first detergent pump 401 and a second detergent pump 402.

[0211] The first detergent flowing out of the first reservoir body 211 can be supplied to the second reservoir 300 via the first detergent pump 401, and the first detergent flowing out of the second reservoir body 212 can be supplied to the second reservoir 300 via the second detergent pump 402.

[0212] That is, in one embodiment of the present disclosure, the first detergent stored in the first reservoir 200 can be transported to the second reservoir 300 through the detergent pump 400, and the first detergent can be supplied to the tub 20 via the second reservoir 300.

[0213] In one example, the receiving housing 310 of the second reservoir 300 may include a first space 313 for receiving the second detergent therein. The drawer 340 may be received in the first space 313, and the drawer 340 may receive the second detergent therein.

[0214] The first detergent flowing into the second reservoir 300 can be mixed with the second detergent and discharged together. Additionally, the water supplied to the second reservoir 300 via the water supply pipe 620 can be mixed with the first detergent and / or the second detergent and then supplied to the tub 20.

[0215] In one embodiment of the present disclosure, the first detergent in the first reservoir 200 needs to be diluted with water before being supplied to the tub 20 to prevent damage to the clothes when the undiluted solution is directly provided to the clothes.

[0216] However, in one embodiment of the present disclosure, the water supply pipe 620 is connected to the second reservoir 300 for mixing the second detergent and water. The first detergent in the first reservoir 200 can be directly put into the second reservoir 300 and diluted with water without the need for a separate mixing tank for mixing with water.

[0217] Therefore, even without a separate mixing tank for mixing the first detergent with water, the first detergent can be diluted, thus effectively eliminating the need for such a mixing tank. In addition to the mixing tank, multiple hoses through which the detergent and water flow can also be eliminated, which is advantageous in terms of space utilization and design.

[0218] In one example, Figure 15 Shows various components disposed in the lid space 140 according to an embodiment of the present disclosure. In one embodiment of the present disclosure, a flow channel structure for a detergent including a first detergent and a second detergent can be installed inside the lid space 140, and a water supply structure through which water flows can also be installed inside the lid space 140.

[0219] In the lid space 140, in addition to the detergent pump 400, the second reservoir 300, and the water supply device 600, various components such as a pump control module 510, a PCB module 520, and a water level detector 530 can be provided. The components of the lid space are generally aligned along the width direction Y of the cabinet 10, so that the limited space can be effectively utilized.

[0220] Furthermore, one embodiment of the present disclosure may include a pump control module 510 for controlling the detergent pump 400, and the pump control module 510 can be aligned with at least one of the plurality of detergent pumps 400 in the vertical direction.

[0221] That is, the pump control module 510 can form a stacked structure with one of the plurality of detergent pumps 400. Therefore, the plurality of detergent pumps 400 and the pump control module 510 can be effectively disposed on one side in the width direction Y of the second reservoir 300.

[0222] In one example, Figure 16 Shows a state in which a plurality of tubes (e.g., the outflow tube 410, the detergent tube 420, the water supply tube 620, etc.) present in the lid space 140 in one embodiment of the present disclosure are removed.

[0223] One embodiment of the present disclosure may include a water level detector 530, and the water level detector 530 can be disposed on the other side of the second reservoir 300 along the width direction Y. The detergent pump 400 can be disposed on one side of the second reservoir 300 along the width direction Y, and the water level detector 530 can be disposed on the other side.

[0224] The water level detector 530 can detect the water level of the water stored in the tub 20. The water level detector 530 can be coupled to the top cover 100 so as to be at least partially disposed in the lid space 140 and can detect the water level of the tub 20.

[0225] The water level detector 530 may include a head and a detection body. The head of the water level detector 530 may be disposed in the cover space 140, and the detection body may extend from the head into the tub 20.

[0226] It is advantageous for the water level detector 530 to extend at least partially in the vertical direction to detect the water level of the tub 20. Additionally, it is more advantageous for the water level detector 530 extending in the vertical direction to have a head fixed above the tub 20.

[0227] Accordingly, the head of the water level detector 530 may be coupled to the top cover 100 located above the tub 20 in the cabinet 10, and the space in which the head of the water level detector 530 is disposed may be fixed in the cover space 140.

[0228] However, to improve space utilization efficiency, since the detergent pump 400 and / or the pump control module 510 may be disposed on one side of the second reservoir 300 inside the cover space 140, the water level detector 530 may be disposed on the other side of the second reservoir 300.

[0229] In one example, an embodiment of the present disclosure may include a PCB module 520, and the PCB module 520 may be disposed on the other side of the second reservoir 300 along the width direction Y. The detergent pump 400 may be disposed on one side of the second reservoir 300 along the width direction Y, and the PCB module 520 including the PCB may be disposed on the other side.

[0230] The PCB module 520 may include a PCB and may be connected to the water level detector 530 and / or other sensors. The PCB module 520 may receive sensed values from the plurality of sensors and control the plurality of sensors.

[0231] The PCB module 520 may be the above-mentioned main controller, or may be a separate control module connected to and spaced apart from the main controller. In addition to the plurality of sensors, the PCB module 520 may also be connected to various components that require electronic control.

[0232] In one example, in an embodiment of the present disclosure, the water level detector 530 and the PCB module 520 may be disposed together on the other side in the width direction Y of the second reservoir 300, and the second reservoir 300, the water level detector 530, and the PCB module 520 may be aligned along the width direction Y.

[0233] Furthermore, the above-mentioned plurality of detergent pumps 400, the second reservoir 300, the water level detector 530, and the PCB module 520 are aligned together along the width direction Y of the cabinet 10, such that the plurality of components may be effectively arranged in the cover space 140 located at the rear of the clothing inlet 101.

[0234] The pump control module 510 and the PCB module 520 having a signal connection relationship, i.e., requiring wire connection, can be respectively located at the outermost edges of the cover space 140. That is to say, the pump control module 510 and the PCB module 520 can be respectively located at the ends in the width direction Y of the cover space 140.

[0235] The top cover 100 can include a front portion 120, a rear portion 130, and side portions connecting the front portion 120 and the rear portion 130 on both sides in the width direction Y of the clothing inlet 101. The pump control module 510 and the PCB module 520 are located at the ends in the width direction Y of the cover space 140 so as to be easily connected to the components of the front portion 120 via wires through the side portions.

[0236] For example, the wire can extend from the front portion 120 to the rear portion 130 through the inside of the side portion, and the pump control module 510 and the PCB module 520 can be easily connected to the control panel 50 or the main controller via the wire extending through the side portion.

[0237] In one example, Figure 17 A second reservoir 300 and a water supply device 600 connected to each other are shown. The water supply device 600 for regulating the flow of water and the receiving housing 310 of the second reservoir 300 can be connected to each other via a water supply module 650.

[0238] The water supply module 650 can be coupled to the water supply valve 610 and the second reservoir 300, and can deliver the water flowing out from the water supply valve 610 to the second reservoir 300.

[0239] The water supply module 650 can include a plurality of water supply pipes 620. That is to say, at least one water flow channel can be formed inside the water supply module 650. In other words, the water supply module 650 can include one or more water inlet holes 651 and one or more water outlet holes 652.

[0240] According to an embodiment of the present disclosure, the water supply valve 610 and the second reservoir 300 are connected to each other using the water supply module 650 including one or more water supply pipes 620, so that the manageability of the water supply pipes 620 can be improved and the durability of the water supply pipes 620 can be ensured.

[0241] The water inlet hole 651 of the water supply module 650 is connected to the water supply valve 610 so that water can flow into the water inlet hole 651. The water outlet hole 652 of the water supply module 650 is connected to the water connection port 322 of the second reservoir 300 so that water can flow out from the water outlet hole 652. The plurality of water inlet holes 651 can be respectively connected to different water supply valves 610, and the plurality of water outlet holes 652 can be respectively connected to different water connection ports 322.

[0242] The water supply module 650 may have more water outlets 652 through which water flows out into the second reservoir 300 than water inlets 651 through which water is introduced from the water supply valve 610. That is, the water supply module 650 may have a branched structure in which a flow channel connected to one water inlet 651 is branched and connected to a plurality of water outlets 652.

[0243] When the target for receiving water is more than the target for supplying water, the above branched structure may be advantageous. For example, in one embodiment of the present disclosure, water from the water supply device 600 is supplied to the second reservoir 300, but within the second reservoir 300, there are multiple areas where water is supplied. Therefore, an effective water supply is achieved using the water supply module 650 including the branched structure.

[0244] In one example, Figure 18 A side view of the second reservoir 300 is shown. The second reservoir 300 may include a receiving housing 310 and a drawer 340. The receiving housing 310 of the second reservoir 300 may form the appearance of the second reservoir 300 and may include the above-described detergent connection port 321 and water connection port 322. The detergent connection port 321 and the water connection port 322 may be provided on the top surface of the receiving housing 310 to facilitate the flow generated by the self-weight of the first detergent and water.

[0245] The receiving housing 310 may include a first chamber 312 and a second chamber 314. The second chamber 314 may have a shape extending or protruding from the first chamber 312. A first space 313 may be defined inside the first chamber 312, and a second space 315 may be defined inside the second chamber 314.

[0246] The first space 313 and the second space 315 may together define the internal space of the receiving housing 310. The drawer 340 that may protrude from the receiving housing 310 may be accommodated in the first space 313 of the first chamber 312. The first detergent may flow into the second space 315 of the second chamber 314.

[0247] The first chamber 312 and the second chamber 314 may communicate with each other. That is, the second space 315 of the second chamber 314 may be in a form extending from the first space 313 of the first chamber 312. The first detergent supplied to the second chamber 314 may flow into the first chamber 312.

[0248] There may be various positions and shapes of the second chamber 314. For example, the second chamber 314 may have a shape protruding backward from the rear wall 318 of the first chamber 312. The second space 315 may be a space protruding backward from the first space 313.

[0249] The bottom surface of the second chamber 314 may be located at a vertical height higher than the vertical height of the bottom surface of the first chamber 312. Due to the vertical height difference between the first chamber 312 and the second chamber 314, the first detergent supplied to the second chamber 314 may generate a flow toward the inside of the first chamber 312.

[0250] The water connection port 322 may be provided on the top surface of the first chamber 312, and the detergent connection port 321 may be provided on the top surface of the second chamber 314. That is, the water supplied to the second reservoir 300 may be provided to the first chamber 312, and the first detergent may be provided to the second chamber 314.

[0251] Accordingly, the first detergent may mainly flow into the second chamber 314, and then flow from the second chamber 314 to the first chamber 312 and mix with the water. The first detergent mixed with the water may be discharged to the outside of the second reservoir 300 via the first chamber 312 and supplied to the tub 20.

[0252] The drawer 340 retracted into the first chamber 312 may store the second detergent therein. When performing a washing process, the user may store the second detergent in the drawer 340 and retract the drawer into the receiving housing 310. When performing a washing process, the second detergent may be mixed with the water supplied to the first chamber 312 and discharged to the outside of the receiving housing 310.

[0253] However, the user may perform a washing process using only the first detergent in the first reservoir 200 without separately storing the second detergent in the second reservoir 300, which may correspond to a manual detergent supply device, may perform a washing process using only the second detergent without separately storing the first detergent in the first reservoir 200, which may correspond to an automatic detergent supply device, or may perform a washing process while the first detergent and the second detergent are separately stored in the first reservoir 200 and the second reservoir 300, respectively.

[0254] In one example, the detergent detector 330 may be provided on the rear wall 318 of the first chamber 312. The detergent detector 330 may be provided on the rear wall 318 of the first chamber 312 between the bottom surface of the first chamber 312 and the bottom surface of the second chamber 314 to detect the first detergent flowing from the second chamber 314 toward the first chamber 312. The detergent detector 330 will be described in detail later.

[0255] The front surface of the receiving housing 310, that is, the front surface of the first chamber 312, may be opened to form an open surface of the housing, and the drawer 340 may be retracted or extended through the open surface of the housing.

[0256] A part of the open surface of the housing can be a detergent discharge area 317, in which the first detergent, the second detergent, or water is discharged into the tub 20. The detergent discharge area 317 can be defined at the lower part of the open surface of the housing.

[0257] In the open surface of the housing, the detergent discharge area 317 can be defined below the drawer 340 received in the receiving housing 310. The first detergent, the second detergent, or water present in the first chamber 312 can flow along the bottom surface of the first chamber 312 due to its own weight, and the bottom surface of the first chamber 312 can be spaced downward from the drawer 340.

[0258] That is to say, the first detergent, the second detergent, or water can flow between the drawer 340 and the bottom surface of the first chamber 312 in the first chamber 312, can be discharged through the detergent discharge area 317 of the open surface of the housing, and can be supplied to the tub 20 due to the falling phenomenon caused by its own weight.

[0259] In one example, as described above, the second reservoir 300 can include a receiving housing 310 and a drawer 340. The receiving housing 310 includes a first chamber 312, and the drawer 340 accommodates the second detergent therein and can extend out of the first chamber 312. The first detergent introduced via the detergent tube 420 and the water introduced via the water supply tube 620 can be mixed with the second detergent in the first chamber 312 and discharged into the tub 20.

[0260] The receiving housing 310 can further include a second chamber 314 connected to the detergent tube 420 and into which the first detergent is introduced. The second chamber 314 and the first chamber 312 can communicate with each other, and the first detergent can be conveyed to the first chamber 312.

[0261] In one example, Figure 19 The drawer 340 extending from the second reservoir 300 in the embodiment of the present disclosure is shown. The drawer 340 can be retracted into the first space 313 or extended out of the first space 313 through the open surface of the housing defined in the front surface of the receiving housing 310.

[0262] The top surface of the drawer 340 can be open, and the user can supply the second detergent into the drawer 340 via the open top surface of the drawer 340. Inside the drawer 340, a first accommodating portion 341 and a second accommodating portion 342 can be defined to be separated from each other, and the second detergent can be stored in the first accommodating portion 341 and the second accommodating portion 342.

[0263] In one example, Figure 20Shows an exploded perspective view of the second storage 300. Referring to Figure 20 , in one embodiment of the present disclosure, the second storage 300 may include a drawer 340, a receiving housing 310, and a water diffuser 370.

[0264] The front surface 345 of the drawer 340 may be exposed in front of the receiving housing 310 and may be exposed to the user via the laundry inlet 101. The front surface 345 of the drawer 340 may form a handle that the user can grasp.

[0265] The water diffuser 370 may be inserted into the receiving housing 310 to diffuse the water supplied to the second storage 300. The water diffuser 370 may include a first diffuser 380 disposed in the first chamber 312 and a second diffuser 390 disposed in the second chamber 314.

[0266] In one example, Figure 21 is a perspective view of the drawer 340. In a state where the drawer 340 is inserted into the receiving housing 310, the front surface 345 of the drawer 340 may form the front surface of the second storage 300. The outer peripheral surface of the laundry inlet 101 of the top cover 100 may be opened at a position corresponding to the second storage 300 to expose the front surface 345 of the drawer 340 to the laundry inlet 101.

[0267] The top surface of the drawer 340 is open so that the user can store the second detergent inside the drawer 340 even when the drawer 340 is completely removed from the receiving housing 310. For example, in a state where the drawer 340 protrudes from the receiving housing 310 such that only a part of the open top surface of the drawer 340 is exposed, the user can store the second detergent via the open top surface.

[0268] The second detergent may be stored inside the drawer 340, and the drawer 340 may include a first accommodation part 341 and a second accommodation part 342, which are defined as spaces separated from each other. The user can store different types of detergents in the first accommodation part 341 and the second accommodation part 342.

[0269] For example, the user can store the detergent in powder form in the first accommodation part 341 and the detergent in liquid form in the second accommodation part 342. The user can store the laundry detergent in the first accommodation part 341 and the fabric softener in the second accommodation part 342.

[0270] A detergent cup 348 may be provided in the second accommodation part 342 of the drawer 340. The detergent cup 348 may provide a space to store the detergent in liquid form and may discharge all the second detergents accommodated in the second accommodation part 342 via siphon effect or the like.

[0271] As described above, in one embodiment of the present disclosure, the difference between the first detergent and the second detergent may be based on the storage objective, rather than the type or form of the detergent.

[0272] Holes or open surfaces may be present in the bottom surface or the rear surface of the drawer 340. The second detergent accommodated in the drawer 340 may leak out of the drawer 340 through the holes or open surfaces defined in the bottom surface or the rear surface of the drawer 340.

[0273] Figure 21 The drawer 340 is shown, in which at least a part of the rear surface of the drawer 340 is open. As will be described later, water may be supplied into the drawer 340, and the second detergent inside the drawer 340 may be discharged to the outside of the drawer 340 together with the water through the open surface or the holes defined in the rear surface of the drawer 340.

[0274] In one example, Figure 22 The receiving housing 310 of the second reservoir 300 is shown. Referring to Figure 22 , the structure of the receiving housing 310 will be summarized as follows.

[0275] The receiving housing 310 may provide a space in which the second detergent is accommodated or a space in which the drawer 340 is accommodated. At least a part of the front surface of the receiving housing 310 may be open to define a housing open surface.

[0276] A part of the housing open surface may define a detergent discharge area 317 for discharging the first detergent, the second detergent, and water from the receiving housing 310. For example, the drawer 340 may be located at the upper part of the housing open surface, and the detergent discharge area 317 may be defined at the lower part of the housing open surface.

[0277] A water diffusion plate may be provided inside the receiving housing 310, and the water diffusion plate may be located above the drawer 340 inside the receiving housing 310. The water flowing into the receiving housing 310 may be conveyed to the drawer 340 and the like through the water diffusion plate.

[0278] In one example, Figure 23 A cross-section of the inside of the second reservoir 300 as viewed from above is shown, and Figure 24 shows Figure 23 the state in which the drawer 340 is disposed inside the receiving housing 310 in

[0279] Referring to Figure 23 and Figure 24, the inflow process of the first detergent into the second reservoir 300 will be described. First, in one embodiment of the present disclosure, the first detergent may be stored in the first reservoir 200. At least a portion of the first reservoir 200 may be exposed to the exterior of the cabinet 10.

[0280] One embodiment of the present disclosure may be a top-loading type, which includes a top cover 100 having a laundry inlet 101 defined therein. The reservoir body 210 of the first reservoir 200 may be exposed to the exterior of the cabinet 10 and may be attached to or detached from the cabinet 10.

[0281] The second reservoir 300 may be disposed inside the cabinet 10 to accommodate the second detergent therein and may communicate with the tub 20. The first reservoir 200 may be an automatic detergent supply device connected to a detergent pump 400, and the second reservoir 300 may be a manual detergent supply device from which the second detergent containing water is discharged.

[0282] The second reservoir 300 may include a first chamber 312 and a second chamber 314. The first chamber 312 may accommodate the second detergent therein and may communicate with the tub 20, and the second chamber 314 may protrude from the first chamber 312 and allow the first detergent to flow into it.

[0283] The first detergent in the second chamber 314 may flow into the first chamber 312 and be discharged into the tub 20 together with the second detergent. The first chamber 312 may include a first space 313 in which the second detergent is accommodated, and the second chamber 314 may include a second space 315 that extends away from the first space 313 and into which the first detergent flows.

[0284] The first detergent may fall along the opposing surfaces in the second space 315 and flow into the first space 313. That is, in one embodiment of the present disclosure, the first detergent in the first reservoir 200 may be supplied to the tub 20 via the second reservoir 300, and the space for the first detergent to flow into may be separately provided from the space in which the second detergent is stored in the second reservoir 300.

[0285] In one embodiment of the present disclosure, the first detergent is supplied to the tub 20 via the second reservoir 300, so that even without a separate mixing tank, the first detergent can be mixed with water and provided via the second reservoir 300. In addition, the first detergent and the second detergent may be supplied to the tub 20 together via the second reservoir 300, thereby effectively simplifying the detergent supply structure.

[0286] In addition, in one embodiment of the present disclosure, the second reservoir 300 has a second chamber 314 (into which the first detergent will be introduced) separate from the first chamber 312 in which the second detergent is stored, so that the scattering range of the first detergent or the exposure range relative to the first detergent can be effectively restricted during the inflow process of the first detergent, thereby facilitating cleaning and improving hygiene.

[0287] For example, when the first detergent flows into the first chamber 312, even when the user does not store the second detergent, the liquid first detergent can be supplied and distributed throughout the first chamber 312, and even when water is supplied to the first chamber 312, the first detergent may remain in areas that are difficult to clean, such as the area between the drawer 340 and the inner surface of the receiving housing 310.

[0288] In addition, when the first detergent scattered in the first chamber 312 is not completely dissolved in water and remains partially, deterioration of the maintenance and manageability of the second reservoir 300 may occur, such as deterioration of the durability of the surface of the drawer 340 caused by the first detergent or the like.

[0289] In addition, as will be described later, the flow path of the first detergent can be separately defined within the second reservoir 300 via the inflow process using the second chamber 314 of the first detergent. Therefore, the detergent detector 330 for sensing the first detergent can be effectively provided inside the second reservoir 300.

[0290] In Figure 23 and Figure 24 The path through which the first detergent flowing into the second space 315 of the second chamber 314 flows into the first space 313 of the first chamber 312 is indicated by an arrow. One surface of the first chamber 312 may be open to communicate with the tub 20, and this one surface may be the above-mentioned housing open surface.

[0291] A part of the opposite surface of the first chamber 312 may be open to communicate with the second chamber 314. The opposite surface of the first chamber 312 may correspond to the rear wall 318 of the first chamber 312. The rear wall 318 of the first chamber 312 may also be structurally defined as the rear wall 318 of the receiving housing 310.

[0292] One surface and the opposite surface of the first chamber 312 may be positioned opposite to each other. That is, in one embodiment of the present disclosure, one surface of the first chamber 312 may be open to communicate with the tub 20 to discharge the first detergent and the second detergent, and its opposite surface may be connected to the second chamber 314 to allow the first detergent to be introduced from the second chamber 314.

[0293] The length of the second chamber 314 in the width direction Y can increase in the direction toward the first chamber 312. That is, the second chamber 314 can include an inclined extension portion 319 that extends obliquely toward the first chamber 312. The inclined extension portion 319 can stabilize the flow of the first detergent introduced into the second chamber 314 and suppress the scattering of the first detergent discharged from the second chamber 314 into the first chamber 312.

[0294] In one example, a transition portion 320 for storing the second detergent in the drawer 340 and for the water flowing out of the drawer 340 and flowing to the bottom surface of the first chamber 312 can be formed on the rear wall 318 of the first chamber 312.

[0295] The transition portion 320 can provide a space for the water supplied to the drawer 340 and the second detergent flowing into the bottom surface defined in the first chamber 312.

[0296] In one example, Figure 25 A cross-section of the inside of the receiving housing 310 as viewed along the width direction Y is shown, and the flow of the first detergent, water, etc. is indicated by arrows. Referring to Figure 25 , the flow path of the first detergent will be described in detail below.

[0297] The receiving housing 310 can include a rear wall 318 located on the opposite side of the open surface of the housing. The second chamber 314 can project rearward from the rear wall 318. However, when needed, the second chamber 314 can project from two side walls other than the rear wall 318 of the first chamber 312.

[0298] The portion of the second chamber 314 projecting from one surface of the first chamber 312 can be spaced upward from the bottom surface of the first chamber 312. The first detergent introduced from the second chamber 314 can flow along the opposite surface toward the bottom surface of the first chamber 312.

[0299] The bottom surface of the second chamber 314 can be located at a vertical height higher than the vertical height of the bottom surface of the first chamber 312. The vertical height difference between the bottom surface of the first chamber 312 and the bottom surface of the second chamber 314 can contribute to generating the flow of the first detergent from the second chamber 314 to the first chamber 312. The bottom surface of the second chamber 314 can be inclined downward in the direction toward the first chamber 312.

[0300] The second reservoir 300 can include a step-forming portion. The step-forming portion can form a portion of the flow path of the first detergent defined inside the second reservoir 300. The step-forming portion can correspond to a part of the rear wall 318 of the first chamber 312.

[0301] The step forming portion can be formed in a stepped shape such that its vertical height relative to the ground is reduced. For example, the step forming portion can be a portion connecting the bottom surface of the first chamber 312 and the bottom surface of the second chamber 314, and due to the vertical height difference between the bottom surface of the first chamber 312 and the bottom surface of the second chamber 314, the step forming portion can have a stepped shape.

[0302] The step forming portion can be located below the second chamber 314 in the rear wall 318 of the first chamber 312. That is, the first detergent discharged from the second chamber 314 can flow along the step forming portion and can reach the bottom surface of the first chamber 312.

[0303] Inside the first chamber 312, the drawer 340 can be spaced apart from the rear wall 318. Therefore, the first detergent in the second chamber 314 can flow to the bottom surface of the first chamber 312 between the drawer 340 and the rear wall 318.

[0304] That is, the second chamber 314 can extend away from the drawer 340 on the outer peripheral surface of the first chamber 312, and the first detergent in the first chamber 312 can flow to the bottom surface of the first chamber 312 through the space between the outer peripheral surface and the drawer 340.

[0305] Specifically, when the first detergent flowing into the second chamber 314 flows to the bottom surface of the first chamber 312 via the step forming portion, a space for the first detergent to flow may be required in front of the step forming portion, that is, between the rear wall 318 of the first chamber 312 and the drawer 340. This space can correspond to the space for storing the first detergent in the drawer 340 and the water flowing out of the drawer 340 and flowing to the bottom surface of the first chamber 312.

[0306] The step forming portion can extend obliquely forward from the second chamber 314 to define a gap with the drawer 340 located in front of the step forming portion.

[0307] In one example, the drawer 340 can be spaced apart from the bottom surface of the first chamber 312 to define a detergent discharge area 317, and the first detergent and the second detergent can flow through the detergent discharge area 317 to be discharged from the receiving housing 310.

[0308] In an embodiment of the present disclosure, the detergent discharge area 317 can be defined as a space and can be defined to include the lower part of the above-mentioned open surface of the housing. The detergent discharge area 317 can be defined as the lower part of the first space 313 and can be defined between the bottom surface of the drawer 340 and the bottom surface of the first chamber 312.

[0309] The bottom surface of the first chamber 312 can be formed to be inclined toward the ground in a direction toward the open surface of the housing, so as to induce the fluid present on the bottom surface of the first chamber 312 to flow toward the open surface of the housing.

[0310] In one embodiment of the present disclosure, the flow path of the first detergent can be defined inside the second reservoir 300. The flow path of the first detergent can include the bottom surface of the second chamber 314, the step forming portion, and the bottom surface of the first chamber 312.

[0311] Specifically, the first detergent flowing through the detergent tube 420 can be discharged into the second space 315 of the second chamber 314 via the detergent connection port 321 of the second reservoir 300. The first detergent supplied to the second chamber 314 can flow along the bottom surface of the second chamber 314 toward the first chamber 312.

[0312] In one example, the first detergent deviating from the second space 315 of the second chamber 314 can flow downward along the step forming portion extending from the bottom surface of the second chamber 314 toward the ground or the bottom surface of the first chamber 312 to the bottom surface of the first chamber 312.

[0313] The first detergent that has flowed from the second chamber 314 into the first chamber 312 can reach the bottom surface of the first chamber 312 by its own weight, and can flow along the bottom surface of the first chamber 312 and be discharged from the second reservoir 300 via the open surface of the housing.

[0314] The open surface of the housing can be located on the tub inlet 22, so that the fluid discharged from the second reservoir 300 can be supplied to the tub 20.

[0315] In one example, with reference to Figure 25 , the flow paths of the first detergent, the second detergent, and water inside the second reservoir 300 will be described as follows.

[0316] First, as described above, the first detergent can pass through the detergent connection port 321, the bottom surface of the second chamber 314, the step forming portion, and the bottom surface of the first chamber 312, and be discharged from the second reservoir 300 via the detergent discharge area 317.

[0317] Water can be supplied to the first chamber 312 via the water connection port 322 provided on the top surface of the first chamber 312. However, as will be described later, the water supplied via the water connection port 322 can be delivered not only to the entire first chamber 312 but also to the inside of the second chamber 314 through the water diffuser 370.

[0318] That is, some of the water supplied from the water connection port 322 can be provided to the first chamber 312, while the remaining water can be provided to the second chamber 314. The water supplied to the second chamber 314 can clean the interior of the second chamber 314 and can flow into the detergent discharge area 317 together with the first detergent in the second chamber 314.

[0319] The second detergent can be accommodated inside the drawer 340, and the water supplied from the water connection port 322 can be provided to the drawer 340. The second detergent can be a detergent in powder form, but can be mixed with the water provided to the drawer 340 and regarded as a fluid.

[0320] The second detergent can be discharged from the drawer 340 together with the water. Since the drawer 340 can be accommodated inside the first chamber 312 of the receiving housing 310, the second detergent discharged from the drawer 340 can ultimately flow toward the bottom surface of the first chamber 312.

[0321] At least a portion of the rear surface of the drawer 340 can be open, and the second detergent and water inside the drawer 340 can flow through the open portion defined in the rear surface of the drawer 340 into the space between the drawer 340 and the rear wall 318 of the first chamber 312.

[0322] Therefore, the second detergent and / or water flowing out of the drawer 340 can be discharged from the second reservoir 300 via the detergent discharge area 317 that can be defined in the bottom surface of the first chamber 312.

[0323] The detergent discharge area 317 can be a common flow path for the first detergent, the second detergent, and the water to flow through. However, in relation to the second detergent, the possibility of the bottom surface or the stepped portion of the second chamber 314 coming into contact with the second detergent is relatively low, so it can be understood as an independent flow path for the first detergent.

[0324] In one example, Figure 26 a detergent detector 330 located on the flow path of the first detergent as observed from the inside of the receiving housing 310 is shown, and Figure 27 a detergent detector 330 provided below the second chamber 314 as observed from the outside is shown.

[0325] Referring to Figure 26 and Figure 27 , an embodiment of the present disclosure can include a detergent detector 330 that senses the first detergent on the flow path of the first detergent. The flow path of the first detergent can be defined within the second reservoir 300.

[0326] The detergent detector 330 can sense the first detergent and / or the second detergent. The detergent detector 330 can be disposed at a point on the flow path of the first detergent. For example, the detergent detector 330 can be disposed on at least one of the bottom surface of the second chamber 314, the step-forming portion, and the bottom surface of the first chamber 312.

[0327] In one example, in one embodiment of the present disclosure, the detergent detector 330 can sense the first detergent, and in this case, the detergent detector 330 can be disposed on the flow path of only the first detergent that is different from the flow path of the second detergent.

[0328] For example, the detergent detector 330 can be disposed in the second chamber 314 or on the step-forming portion. In addition, when the first detergent or the like adheres to the surface of the detergent detector 330, it may cause a failure of the detergent detector 330. Therefore, the detergent detector 330 can be disposed on the step-forming portion extending toward the ground to prevent the adhesion of the first detergent or the like.

[0329] The step-forming portion can correspond to a portion of the rear wall 318 in the receiving housing 310 that is substantially perpendicular to the ground. Therefore, the risk of adhesion or the like can be reduced at the detergent detector 330 disposed on the step-forming portion because the first detergent or the like flows due to its own weight.

[0330] That is, the detergent detector 330 can be disposed on the rear wall 318 of the first chamber 312 and can be located below the second chamber 314 on the rear wall 318 of the first chamber 312. That is, the detergent detector 330 can be disposed on the step-forming portion at a position below the second chamber 314, and the step-forming portion connects the bottom surface of the first chamber 312 and the bottom surface of the second chamber 314.

[0331] When viewed from the inside of the second reservoir 300, the detergent detector 330 can be located below the bottom surface of the second chamber 314 on the rear wall 318 of the receiving housing 310. The detergent detector 330 can be disposed between the bottom surface of the second chamber 314 and the bottom surface of the first chamber 312 on the flow path of the first detergent.

[0332] The detergent detector 330 can be of various types and can sense the first detergent or the like. For example, the detergent detector 330 can be formed in the shape of an electrode sensor including at least a pair of electrodes 331.

[0333] At least a part of the electrode 331 of the detergent detector 330 may be exposed to the interior of the second reservoir 300. When the first detergent contacts the pair of electrodes 331, a specific pattern is recorded in the sensing result of the detergent detector 330, which allows identification of the presence of the first detergent.

[0334] In one embodiment of the present disclosure, the detergent detector 330 is located inside the second reservoir 300 to which water is supplied, so that the surface of the detergent detector 330 can be easily cleaned with water. In one embodiment of the present disclosure, a separate mixing tank for mixing the first detergent and water is omitted, and the first detergent and water are mixed with each other via the second reservoir 300. Therefore, since the detergent detector 330 is provided on the step-forming portion of the second reservoir 300, the maintenance of the detergent detector 330 can be easy, and the first detergent can be effectively sensed.

[0335] In one example, the detergent detector 330 may have a partition rib 332 protruding between the pair of electrodes 331. The partition rib 332 may protrude from the detergent detector 330 toward the interior of the second reservoir 300 and may extend along the flow path of the first detergent.

[0336] Even when the first detergent or the like adheres to the surface, the detergent detector 330 can prevent the first detergent or the like from contacting the pair of electrodes 331 via the partition rib 332, thereby effectively reducing false detection of the detergent detector 330. The detergent detector 330 may be electrically connected to the pump control module 510 or the PCB module 520 described above.

[0337] In one example, Figure 28 A cross-section of the detergent connection port 321 and the second chamber 314 is shown, and Figure 29 The detergent discharge hole 327 is shown as viewed from the second space 315 of the second chamber 314.

[0338] Referring to Figure 28 and Figure 29 , the detergent connection port 321 including the connecting portion 325 may protrude from the second chamber 314, and the detergent connection port 321 may communicate with the detergent discharge hole 327 defined in the top surface of the second chamber 314.

[0339] The detergent discharge hole 327 may also be understood as a hole defined at one end of the detergent connection port 321. When viewed from the inside of the second chamber 314, the first detergent may be introduced via the detergent discharge hole 327 defined in one surface of the second chamber 314.

[0340] In one embodiment of the present disclosure, the detergent discharge hole 327 may have a smaller area size than the detergent tube 420 or the detergent connection port 321. In other words, the cross-sectional area of the detergent discharge hole 327 may be smaller than the flow cross-sectional area defined in the detergent tube 420 or the detergent connection port 321 for the first detergent. That is to say, the detergent discharge hole 327 may have a smaller area size than the flow path in the detergent tube 420.

[0341] In other words, the second chamber 314 may include a shielding portion 328 that blocks a part of the flow path in the detergent tube 420 or the detergent connection port 321. The shielding portion 328 may be provided on the detergent discharge hole 327.

[0342] That is to say, one embodiment of the present disclosure may include a shielding portion 328 that shields a part of the detergent discharge hole 327 defined at one end of the detergent connection port 321. In Figure 29 which, the substantially circular detergent discharge hole 327 is represented by a dashed line in the top surface of the second chamber 314, and the shielding portion 328 that partially blocks the detergent discharge hole 327 is shown.

[0343] In one embodiment of the present disclosure, due to the shielding portion 328 and the like, the cross-sectional area of the detergent discharge hole 327 is smaller than the cross-sectional area of the detergent connection port 321. Therefore, when the first detergent passes through the detergent discharge hole 327, a flow resistance of the first detergent flowing along the detergent connection port 321 may occur. As a result, the flow rate of the first detergent discharged into the second chamber 314 can be reduced, thereby suppressing scattering and the like of the first detergent.

[0344] In one example, Figure 30 is a perspective view of a water diffuser 370 according to an embodiment of the present disclosure, and Figure 31 is a top view of the water diffuser 370.

[0345] Referring to Figure 30 and Figure 31 , the water diffuser 370 is disposed in the first chamber 312 and extends into the second chamber 314 to convey the water supplied to the first chamber 312 toward the second chamber 314.

[0346] For example, a water supply pipe 620 that guides the water supplied from a water supply source may be connected to the first chamber 312, and the second reservoir 300 may supply the water supplied to the first chamber 312 to the second chamber 314.

[0347] As described above, water can be supplied to the second chamber 314 for diluting the first detergent and cleaning the interior of the second chamber 314 and the detergent detector 330. However, due to the property of the second chamber 314 that restricts the scattering or diffusion area of the first detergent, the volume of the second space 315 needs to be smaller than the volume of the first space 313.

[0348] However, when the second chamber 314 is equipped with a separate water connection port 322 for water supply in addition to the detergent connection port 321, the volume of the second chamber 314 may be unnecessarily increased, and with the water directly supplied via the water supply pipe 620, scattering of the first detergent may occur due to high water pressure, etc.

[0349] Therefore, in an embodiment of the present disclosure, the water connection port 322 is provided in the first chamber 312, and at least some of the water supplied to the first chamber 312 is delivered to the second chamber 314 via the water diffuser 370, so that it is not necessary to connect a separate water supply pipe 620 to the second chamber 314, and water can be supplied with regulated water pressure, etc.

[0350] The water diffuser 370 can be formed in a substantially plate shape and can be installed inside the receiving housing 310. The water diffuser 370 can be formed in a panel shape that spans the space between the top surface and the bottom surface of the receiving housing 310. The water diffuser 370 can have an area size and shape corresponding to the area size and shape of the top surface of the receiving housing 310.

[0351] The water diffuser 370 can include a plurality of drain holes 371 for allowing water to fall. The number, size, shape, etc. of the plurality of drain holes 371 can be determined in various ways as needed.

[0352] The water diffuser 370 can be provided below the water connection port 322. The water discharged from the water connection port 322 can be mainly located on the water diffuser 370 and can secondly fall toward the bottom surface of the receiving housing 310 via the drain holes 371 of the water diffuser 370, etc.

[0353] That is, the water diffuser 370 can define a residence space in which water stays between the water connection port 322 and the water diffuser 370, and the water in the residence space can be discharged into the receiving housing 310 at a position, flow rate, flow velocity, etc. of the water to be supplied that is regulated via the drain holes 371 of the water diffuser 370. The water diffuser 370 can include a plurality of ribs protruding toward the top surface of the receiving housing 310 to guide the flow of water.

[0354] In one example, the water diffuser 370 may include a first diffuser 380 and a second diffuser 390. The first diffuser 380 may be located inside the first chamber 312, and the second diffuser 390 may be located inside the second chamber 314.

[0355] The first diffuser 380 may have a shape generally corresponding to the shape of the top surface of the first chamber 312, and the second diffuser 390 may have a shape generally corresponding to the shape of the top surface of the second chamber 314. The second diffuser 390 may extend from the first diffuser 380 located in the first chamber 312 toward the interior of the second chamber 314.

[0356] At least a portion of the first diffuser 380 may be located below the water connection port 322, and the water falling from the water connection port 322 may pass through the first diffuser 380 and flow to the second diffuser 390, and thus be supplied into the second chamber 314.

[0357] The first diffuser 380 may have a plurality of drain holes 371 defined therein to drain water into the first chamber 312, for example, into the drawer 340. The first diffuser 380 may have an area size corresponding to the area size of the drawer 340. The second detergent may be accommodated below the first diffuser 380.

[0358] The first diffuser 380 may include a 1-1 diffuser 382 and a 1-2 diffuser 384. The 1-1 diffuser 382 may be located above the first accommodation portion 341 of the drawer 340, and the 1-2 diffuser 384 may be located above the second accommodation portion 342 of the drawer 340.

[0359] In one example, the water diffuser 370 may include an anti-overflow portion 372. The anti-overflow portion 372 may include a circumferential portion protruding toward the top surface of the receiving housing 310, and may include an anti-overflow hole surrounded by the circumferential portion.

[0360] When the amount of water stagnating on the water diffuser 370 increases to an amount equal to or greater than a certain amount, the anti-overflow portion 372 may quickly drain the water from the retention space, thereby reducing the flow pressure in the retention space.

[0361] The size of the anti-overflow hole may be larger than the size of the drain hole 371, and the number, size, position, etc. of the anti-overflow holes may be determined in various ways based on needs. When the water level of the water stagnating on the water diffuser 370 is higher than the vertical height of the circumferential portion of the anti-overflow portion 372, the water in the retention space may be discharged in a relatively large amount via the anti-overflow portion 372.

[0362] In one example, in one embodiment of the present disclosure, the water diffuser 370 may include an inclined forming portion 373. The inclined forming portion 373 may be located between the first diffuser 380 and the second diffuser 390, and may be formed to be inclined to guide water from the first diffuser 380 to the second diffuser 390.

[0363] The inclined forming portion 373 may include one end of the first diffuser 380. That is, the inclined forming portion 373 may be formed at one end of the first diffuser 380. As described above, in one embodiment of the present disclosure, water and detergent may flow between the drawer 340 and the rear wall 318 of the receiving housing 310. Therefore, the inclined forming portion 373 may be provided at the rear end of the first diffuser 380.

[0364] In addition, in one embodiment of the present disclosure, since the second chamber 314 may be provided on the rear wall 318 of the first chamber 312, the inclined forming portion 373 may be located between the first diffuser 380 and the second diffuser 390. Due to the inclined forming portion 373, the vertical height of the second diffuser 390 may be lower than the vertical height of the first diffuser 380.

[0365] The inclined forming portion 373 may be formed to slope downward from the first diffuser 380. Therefore, the water on the first diffuser 380 may flow through the inclined forming portion 373 toward the rear portion of the first diffuser 380, that is, toward the rear wall 318 of the receiving housing 310.

[0366] The water flowing toward the rear wall 318 of the first diffuser 380 may flow along the space between the drawer 340 and the rear wall 318 of the receiving housing 310, the transition portion 320 provided on the rear wall 318 of the receiving housing 310, and / or the second diffuser 390.

[0367] The second diffuser 390 may include a guiding rib that extends in a direction away from the first diffuser 380 and guides water. The guiding rib may be provided on the second diffuser 390 and may be in the form of a rib that extends along the extending direction of the second diffuser 390 with respect to the first diffuser 380.

[0368] The guiding rib projects toward the top surface of the second chamber 314 and extends in a direction away from the first diffuser 380 to allow the water on the second diffuser 390 to flow toward the rear portion of the second chamber 314.

[0369] In one example, Figure 32The water diffuser 370 disposed inside the receiving housing 310 is shown. The top surface of the second chamber 314 may have a detergent discharge hole 327 defined therein, through which the first detergent is discharged, and the second diffuser 390 may be open at a portion corresponding to the detergent discharge hole 327 to allow the first detergent to pass therethrough.

[0370] In other words, the first detergent discharged through the detergent discharge hole 327 may not stay on the second diffuser 390, but may pass through the second diffuser 390 and be supplied into the second chamber 314. Accordingly, a situation where the first detergent unnecessarily contacts the second diffuser 390 can be suppressed, and a situation where the distribution area of the first detergent is increased via the water diffuser 370 can be suppressed. The size or shape of the open area for the first detergent to pass through the second diffuser 390 may vary.

[0371] The first diffuser 380 has a drain hole 371 defined therein, so that water can be supplied into the second chamber 314. Since the water in the second diffuser 390 is discharged through the open area corresponding to the detergent discharge hole 327, a situation where the first detergent flows onto the water diffuser 370 due to the flow of water can be suppressed.

[0372] Figure 33 The fluid flow inside the receiving housing 310 including the water diffuser 370 is schematically shown. Referring to Figure 33 , the flow of water through the water diffuser 370 inside the receiving housing 310 will be described as follows.

[0373] The water connection port 322 may be provided on the top surface of the first chamber 312, and the water discharged through the water connection port 322 may mainly stay in the staying space between the first diffuser 380 of the water diffuser 370 and the top surface of the first chamber 312.

[0374] The water diffuser 370 may be designed such that the flow rate of the water discharged through the plurality of drain holes 371 is smaller than the flow rate of the water introduced through the water connection port 322. This can be achieved by adjusting the size or number of the drain holes 371.

[0375] Secondly, some of the water staying on the water diffuser 370 may fall through the drain hole 371 defined in the first diffuser 380 and be supplied into the first chamber 312 or the drawer 340. The remaining part of the water staying on the water diffuser 370 may flow toward the second diffuser 390, be discharged along the rear wall 318 of the first chamber 312, or be discharged through the anti-overflow portion 372.

[0376] Water flowing into the drawer 340 through the first diffuser 380 can pass through the rear surface of the drawer 340 together with the second detergent and flow along the bottom surface of the first chamber 312.

[0377] In one example, water flowing into the second diffuser 390 through the inclined forming portion 373, the guide rib, etc. can fall toward the bottom surface of the second chamber 314. The water supplied to the second chamber 314 can be mixed with the first detergent, clean the interior of the second chamber 314 and the detergent detector 330, and reach the bottom surface of the first chamber 312 via the step forming portion.

[0378] The water supplied to the receiving housing 310 can finally pass through the first diffuser 380 and the second diffuser 390, flow along the detergent discharge area 317 formed on the bottom surface of the first chamber 312, and be discharged through the open surface of the housing.

[0379] Although the present disclosure has been illustrated and described in connection with specific embodiments, it will be apparent to those skilled in the art that the present disclosure can be variously modified and changed without departing from the technical spirit of the present disclosure provided by the claims.
