[0070] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments used to disclose the concept of the present invention. Other inventions can be proposed by adding, changing, or deleting other constituent elements, or other embodiments that are included within the scope of the present invention can be easily proposed.

[0071] Before proceeding with the explanation, let's first define the direction. In this embodiment of the invention, with... Figure 1 , Figure 2 Using the center point of the washing machine shown as a reference, the direction toward the ground where the washing machine is installed can be defined as downward, the direction toward the surface with the inlet formed in the cabinet can be defined as upward, the direction toward the surface with the back panel can be defined as rearward, and the direction toward the surface opposite to the rearward can be defined as frontward. Furthermore, when undefined directions are mentioned, they will be defined and explained based on the respective accompanying drawings.

[0072] Furthermore, this embodiment of the invention is illustrated using a pulsator-type washing machine with a door formed on its upper surface, through which laundry is placed. However, it should be stated firstly that the invention is not limited to the structure and form of the washing machine and can be applied to washing machines of all types equipped with a detergent supply device. For example, the invention can be applied to various types of washing machines, including drum washing machines.

[0073] Figure 1 This is a perspective view of a washing machine according to an embodiment of the present invention. Figure 2 This is the rear view of the washing machine mentioned above.

[0074] Reference Figure 1 as well as Figure 2 According to an embodiment of the present invention, the washing machine 1 may include a cabinet 10, an upper frame 12 placed on the upper surface of the cabinet 10, a door 13 rotatably connected to the upper frame 12, and a control panel 14 installed on the rear edge of the upper frame 12.

[0075] In detail, the cabinet 10 forms the exterior of the washing machine 1, and the interior can form a washing space.

[0076] As an example, the cabinet 10 can be formed in a hexahedral shape with an opening on the upper surface, and the upper frame 12 covers the upper surface of the opening of the cabinet 10. Furthermore, the upper frame 12 has an insertion port 101 (see reference). Figure 3 The aforementioned door 13 opens and closes the aforementioned input port 101.

[0077] Additionally, a tub 11 communicating with the inlet 101 is housed inside the cabinet 10. The upper surface of the tub 11 is open, communicating with the inlet 101, and a washing basin for holding laundry can be housed inside the tub 11. The washing basin may include a cylindrical drum. Furthermore, a drive device including a motor for driving the drum may be installed inside the cabinet 10.

[0078] As an example, the control panel 14 can be located on the upper surface of the upper frame 12, corresponding to the rear side of the inlet 101. Furthermore, the control panel 14 may include an operating component 141 for operating the washing machine 1. As an example, the operating component 141 may include a knob and buttons. Additionally, the control panel 14 may also include a display for showing the operation of the washing machine 1.

[0079] The rear end of the door 13 is rotatably connected to the upper frame 12, allowing the user to open or close the inlet 101 by lifting or lowering the front end of the door 13. Furthermore, at least a portion of the door 13 can be made transparent. Therefore, the user can view the interior of the washing tub through the transparent portion of the door 13.

[0080] On the other hand, the back of the cabinet 10 can be formed by a back cover 102. When the back cover 102 is separated or removed, it becomes accessible for maintenance of the components located inside the washing machine 1. For example, when the back cover 102 is separated, the power supply device 16, water level sensor 17, water supply device 15, etc., which are located on the control panel 14, can be replaced or repaired.

[0081] Additionally, a water supply pipe connection 152 may be provided on the back of the aforementioned cabinet 10. A water supply pipe extending from an external water source may be connected to the aforementioned water supply pipe connection 152. The aforementioned water supply pipe connection 152 may be the water supply device 15 described later (see reference). Figure 4The water supply device 15 includes multiple valves that can be connected to the detergent supply device 20 disposed inside the cabinet 10. The water supply pipe connection 152 may include a hot water pipe connection 152a for supplying hot water and a cold water pipe connection 152b for supplying cold water. The water supply device 15 will be described in more detail below with reference to the accompanying drawings.

[0082] The detergent supply device 20 can be located on one side of the inlet 101, specifically, on the rear side of the inlet 101. The detergent supply device 20 is configured to be pulled forward from the rear edge of the inlet 101, allowing the user to add detergent into it. Furthermore, the detergent supply device 20 is connected to the water supply device 15, so that the detergent added to the detergent supply device 20 mixes with the water supplied from the water supply device 15 and is then supplied to the interior of the tank 11.

[0083] The detergent supply device 20 described above will now be described in more detail with reference to the accompanying drawings.

[0084] Figure 3 This is a perspective view of the upper frame showing the detergent dispenser in the extended position. Figure 4 This is a top view of the aforementioned detergent supply device. Figure 5 This is a perspective view of the aforementioned detergent supply device.

[0085] Reference Figures 3 to 5 The upper surface of the cabinet 10 is joined to the upper frame 12 that forms the input port 101.

[0086] Specifically, the upper frame 12 forms the upper part of the washing machine 1, and the inlet 101 can be concealed by the door 13. Additionally, the control panel 14 can be disposed on the rear side of the upper surface of the upper frame 12.

[0087] Furthermore, the upper frame 12 may be equipped with the detergent supply device 20. The detergent supply device 20 can be inserted into a frame opening 121 formed on one side of the inlet 101, specifically on the rear surface of the inlet 101. Additionally, the detergent supply device 20 is installed inside the upper frame 12 through the frame opening 121. The detergent supply device 20 includes a housing 30 fixed inside the upper frame 12, a detergent cartridge 50 connected to the housing 30 in an infeedable manner, and a flow path member 40 connected to the housing 30 to form a flow path for supplying water to the detergent cartridge 50. Furthermore, when the detergent cartridge 50 is closed, i.e., inserted inside the housing 30, the front surface of the detergent cartridge 50 may form part of the rear surface of the inlet 101.

[0088] The detergent supply device 20 can be disposed at the lower center of the control panel 14. Furthermore, corresponding to the left and right edges of the detergent supply device 20, the control panel 14 can be provided with a power supply device 16 for supplying power to drive the washing machine 1 and a water level sensor 17 for detecting the water level in the tub 11, respectively. Additionally, a PCB electrically connected to various components, including the operating section, disposed on the front surface of the control panel 14 can be disposed in the central portion of the control panel 14, corresponding to the upper side of the detergent supply device 20.

[0089] Furthermore, the water supply device 15 can be connected to the rear end of the detergent supply device 20. In addition, when the detergent supply device 20 is installed, the water supply device 15 can be exposed to the outside from the back of the washing machine 1 and connected to the water supply pipe.

[0090] The water supply device 15 can be connected to the housing 30 of the detergent supply device 20. Specifically, the water supply device 15 can be positioned at a point on the left or right side of the back surface of the housing 30. As an example, the water supply device 915 can be connected to a point closer to the right edge of the back surface of the housing 30. This off-center configuration of the water supply device 15 facilitates the arrangement of wires connecting to the multiple valves 152, 153, and 154 constituting the water supply device 15. Furthermore, by effectively arranging other electronic components inside the control panel 14, interference with the water supply device 15 can be minimized.

[0091] The aforementioned water supply device 15 may include a water supply body 151 having the aforementioned water supply pipe connection portion 152 and a plurality of valves 153 and 154 connected to the aforementioned water supply body 151. As described above, the aforementioned water supply pipe connection portion 152 may include a hot water connection portion 152a and a cold water connection portion 152b protruding rearward.

[0092] Additionally, the aforementioned valve may include a hot water valve 153 and a cold water valve 154. The hot water valve 153 can selectively supply hot water supplied through the hot water connection 152a to the detergent supply device 20. Furthermore, the cold water valve 154 can selectively supply cold water supplied through the cold water connection 152b to the detergent supply device 20.

[0093] The aforementioned cold water valve 154 may include a first cold water valve 154a and a second cold water valve 154b. The first cold water valve 154a can be understood as a valve that selectively supplies cold water to either the first receiving portion 54 or the second receiving portion 55, which will be described below. Furthermore, the second cold water valve 154b can be understood as a valve that selectively supplies cold water to the third receiving portion 56, which will be described below. The first cold water valve 154a and the second cold water valve 154b are configured to cross each other in directions away from each other, which can prevent incorrect wiring or minimize the possibility of incorrect wiring.

[0094] On the other hand, an additional water supply section 156 may also be formed in the aforementioned water supply main body 151. The additional water supply section 156 may be configured to directly spray water into the aforementioned tub 11. The additional water supply section 156 can further improve the efficiency of the washing operation. The additional water supply section 156 may extend further to the side of the aforementioned detergent supply device 20. In addition, the additional water supply section 156 is also provided with an additional valve 155, thereby enabling the opening and closing of the flow path for directly spraying water into the aforementioned tub 11.

[0095] The water supply device 15 is connected to the back of the outer casing 30, and the flow path component 40 is installed on the upper surface inside the outer casing 30, thereby forming a flow path communicating with the water supply device 15. Furthermore, the flow path component 40 is positioned above the detergent dispenser 50 when the detergent dispenser 50 is closed. Therefore, water can fall from above the detergent dispenser 50 through the flow path component 40, and the falling water mixes with the detergent added to the detergent dispenser 50 before being supplied to the tank 11.

[0096] As an example, the detergent dispenser 50 may have a receiving portion 53. Specifically, the receiving portion 53 may include a first receiving portion 54, a second receiving portion 55, and a third receiving portion 56. Furthermore, the flow path component 40 may have a separate flow path leading to each of the first receiving portion 54, the second receiving portion 55, and the third receiving portion 56. That is, by mounting one flow path component 40 to the housing 30, multiple flow paths are provided that can supply water to each of the multiple receiving portions 54, 55, and 56 formed in the detergent dispenser 50.

[0097] The detailed structure of the housing 30, flow path component 40, and detergent box 50 constituting the water supply device 15 described above is described in detail below with reference to the accompanying drawings.

[0098] Figure 6 This is a split perspective view showing the detergent dispenser separated from the outer casing of the aforementioned detergent supply device, as seen from the front. Figure 7 This is a split perspective view of the detergent dispenser from the rear, with the dispenser separated from the outer casing. Figure 8This is a split perspective view of the aforementioned detergent supply device.

[0099] Reference Figures 6 to 8 The aforementioned outer casing 30 can be molded into a box shape with an open front surface, and the interior can form a receiving space 300 for accommodating the aforementioned flow path component 40 and detergent dispenser 50. As an example, the aforementioned outer casing 30 can be molded as a single piece by plastic injection molding.

[0100] A water supply device 15 can be connected to the back of the outer casing 30. Water supplied by the water supply device 15 can be supplied to the detergent dispenser 50 after passing through the flow path component 40. Therefore, the flow path component 40 can be integrated into the interior of the outer casing 30.

[0101] Specifically, the aforementioned flow path component 40 can be installed on the upper surface inside the housing 30. Furthermore, the flow path component 40 can form multiple flow paths with openings on its upper surface. Therefore, when the flow path component 40 is installed on the housing 30, one or more flow paths for supplying water to the detergent dispenser 50 can be formed through the housing 30 and the flow path component 40. Additionally, with the flow path component 40 installed, the one or more flow paths can communicate with the water supply device 15.

[0102] The aforementioned flow path component 40, when installed on the housing 30, can be positioned on the upper side of the detergent dispenser 50. Furthermore, the front end of the flow path component 40 can extend to the front end of the upper surface of the housing 30. Therefore, water can fall onto the detergent dispenser 50 over the entire area of ​​the upper surface of the receiving space 300.

[0103] The aforementioned receiving space 300 can accommodate the aforementioned detergent dispenser 50. The detergent dispenser 50 is configured to be accessible through the front surface of the opening in the aforementioned housing 30. The detergent dispenser 50 can be formed in the form of a drawer, and can have multiple downwardly recessed receiving sections 53. Detergent for washing can be filled into the multiple receiving sections 53.

[0104] As an example, the aforementioned receiving section 53 may include a first receiving section 54 for receiving powdered detergent, a second receiving section 55 for receiving liquid detergent, and a third receiving section 56 for receiving fabric softener. Needless to say, the second receiving section 55 or the third receiving section 56 may be omitted if necessary.

[0105] The flow path formed in the flow path component 40 can be formed on the upper side corresponding to the first receiving portion 54, the second receiving portion 55, and the third receiving portion 56. In addition, the water supplied from the water supply device 15 can be diverted to the first receiving portion 54, the second receiving portion 55, and the third receiving portion 56 for individual supply.

[0106] On the other hand, a mixing component 60 may be provided inside the first receiving portion 54. The mixing component 60 may be formed in the shape of a fan or propeller with multiple blades. Furthermore, the mixing component 60 is rotatably disposed in the first receiving portion 54. The mixing component 60 can be driven through a nozzle 451 (see reference 451) formed in the flow path component 40. Figure 15 The sprayed water rotates. The aforementioned mixing component 60 can be defined as a mixing component or a mixing fan.

[0107] With powdered detergent contained in the first receiving section 54, when washing water is supplied through the nozzle 451, the mixing member 60 rotates, simultaneously mixing the washing water and the powdered detergent. Alternatively, the powdered detergent can be supplied to the container 11 in a state where it is dissolved in water within the first receiving section 54. For this purpose, at least a portion of the back side of the first receiving section 54 can be opened.

[0108] A cover 57 may be disposed on the second receiving portion 55 and the third receiving portion 56. The cover 57 is placed on the upper surface of the openings of the second receiving portion 55 and the third receiving portion 56, and may be formed to slope downwards according to the concave shape of the second receiving portion 55 and the third receiving portion 56. Furthermore, cover holes 571, 572, 575, and 576 (see reference) may be formed at the bottom of the concave portion of the downwardly sloped cover 57 and at the rear end of the cover 57 for supplying water falling from the flow path member 40. Figure 17 In this embodiment, the cover 57 is integrally formed and has recesses corresponding to the second and third receiving portions 55 and 56. However, it may also be provided as separate components that cover the second and third receiving portions 55 and 56 respectively.

[0109] The above-mentioned outer casing 30 will now be described in more detail with reference to the accompanying drawings.

[0110] Figure 9 This is a perspective view of the housing with the flow path components, viewed from the lower front side. Figure 10 This is a top-view, exploded perspective view of the aforementioned outer casing and flow path components. Figure 11 This is a split perspective view of the aforementioned outer casing and flow path components viewed from below.

[0111] Reference Figures 9 to 11 The aforementioned housing 30 can be configured as a hexahedron with an open front surface and an internal receiving space 300. As an example, the aforementioned housing 30 may include an upper housing surface 31, a lower housing surface 32, a pair of housing side surfaces 33, and a housing back surface 34.

[0112] A housing mounting portion 311 may be formed on the upper surface 31 of the aforementioned housing. The housing mounting portion 311 can be coupled to the aforementioned upper frame 12. As an example, the housing mounting portion 311 may include a boss for fastening a screw, which may be formed on the frame fastening portion 122 (see reference) of the upper frame 12. Figure 3 The corresponding position. In addition, the screw passing through the above-mentioned frame fastening part 122 is fastened to the above-mentioned housing mounting part 311, so that the above-mentioned housing 30 can be fixed to the above-mentioned upper frame 12.

[0113] Furthermore, a side mounting portion 331 may be formed protruding from the outer surface of the aforementioned housing side 33. Specifically, the side mounting portion 331 protrudes laterally from the aforementioned housing side 33, and a screw passing through the aforementioned side mounting portion 331 is coupled to the aforementioned upper frame 12, thereby the aforementioned housing 30 can be firmly fixed inside the aforementioned upper frame 12.

[0114] A stepped housing guide 332 is formed on the side 33 of the housing to guide the detergent dispenser 50 in and out, and a detergent dispenser guide 513 is formed on the detergent dispenser 50 (see reference). Figure 17 The detergent dispenser guide 513 is placed on the upper surface of the housing guide 332. The housing guide 332 can extend from the front end to the rear end of the housing side 33. In addition, the housing guide 332 forms a step in the central direction of the receiving space 300, so that the detergent dispenser guide 513 can be placed on the upper surface of the housing guide 332.

[0115] A detergent dispenser restraint portion 333 may be formed at the rear end of the aforementioned housing side surface 33. The detergent dispenser restraint portion 333 may extend from a point separating it from the front end of the aforementioned housing side surface 33 toward the rear end of the aforementioned housing side surface 33. In addition, the detergent dispenser restraint portion 333 protrudes downward from the upper surface of the aforementioned housing 30 and is located above the aforementioned housing guide 332.

[0116] Furthermore, the detergent dispenser limiting part 333 is equipped with an elastic member. When the detergent dispenser 50 is fully pushed into the outer casing 30, the elastic member presses against the limiting protrusion 514 of the detergent dispenser 50 (see reference). Figure 17 The upper surface of the detergent dispenser 50 is designed to restrict its extension. That is, the detergent dispenser 50 can only be extended when the user pulls it with a force that overcomes the elasticity of the elastic component.

[0117] A casing outlet 321 may be formed on the lower surface 32 of the casing to allow the washing water mixed with detergent in the detergent container 50 to fall downwards. Multiple casing outlets 321 may be formed in the region adjacent to the front end 322 of the lower surface 32 of the casing. Furthermore, the front end 322 of the lower surface 32 of the casing may be formed in a rearwardly recessed shape. For example, the front end 322 of the lower surface 32 of the casing may have a shape where the central portion is more recessed than the left and right sides. Therefore, it becomes longer than the case where the front end 322 is a straight line, allowing the washing water flowing along the lower surface 32 of the casing to fall evenly over a wider area.

[0118] The water supply device 15 can be installed on the back surface 34 of the aforementioned housing. Additionally, a rearwardly protruding connection port 341 can be formed on the back surface 34 of the aforementioned housing. The connection port 341 can be connected to the aforementioned water supply body 151. The connection port 341 may include a hot water inlet 342 and a cold water inlet 343. Furthermore, the cold water inlet 343 may include a first cold water inlet 343a and a second cold water inlet 343b.

[0119] The hot water inlet 342, the first cold water inlet 343a, and the second cold water inlet 343b can be arranged side-by-side on the same plane. When the water supply device 15 is installed, the hot water inlet 342 can be opened and closed via the hot water valve 153, and the first cold water inlet 343a and the second cold water inlet 343b can be opened and closed via the first cold water valve 154a and the second cold water valve 154b, respectively. Furthermore, when the flow path component 40 is installed, the hot water inlet 342, the first cold water inlet 343a, and the second cold water inlet 343b are connected to the distribution flow path 43 formed in the flow path component 40.

[0120] The flow path component 40 can be formed to correspond to the size of the upper surface 31 of the housing. As an example, the flow path component 40 can be formed to such a size that, when mounted on the upper surface 31 of the housing, the front and rear ends of the flow path component 40 extend to the front and rear ends of the upper surface 31 of the housing, and the left and right ends of the flow path component 40 extend to the left and right ends of the upper surface 31 of the housing.

[0121] Furthermore, the rear end of the aforementioned flow path component 40 may extend downward and connect with the back surface 34 of the aforementioned housing. Additionally, the back surface of the aforementioned flow path component 40 may communicate with the connection port 341 connected to the aforementioned water supply device 15.

[0122] The aforementioned flow path component 40 may include a distribution flow path 43 for supplying water to the aforementioned receiving section 53 and a discharge flow path 44. Furthermore, the discharge flow path 44 may be formed with a predetermined recess depth, and by combining with the aforementioned housing 30, separate flow paths can be formed. The structure and function of the aforementioned flow path component 40, including the aforementioned plurality of flow paths 43 and 44, will be described in more detail below with reference to the accompanying drawings.

[0123] Figure 12 This is a top view of the flow path components. Figure 13 This is a three-dimensional view of the flow path components as seen from above. Figure 14 This is a three-dimensional view of the aforementioned flow path components from the rear. Figure 15 This is a perspective view of the flow path components viewed from below. Figure 16 It is along Figure 5 A 3D view of a 16-16 cut.

[0124] Reference Figures 12 to 16 The aforementioned flow path component 40 may include an upper portion 41, a rear portion 42, and a corner R where the rear end of the upper portion 41 and the upper end of the rear portion 42 meet. The upper portion 41 can be defined as the surface facing the upper surface 31 of the outer casing. Furthermore, a portion of the upper portion 41 contacts the upper surface 31 of the outer casing, while another portion is recessed, thereby forming a flow path for water supplied to the detergent dispenser 50. That is, the upper surface of the opening of the flow path formed in the flow path component 40 can be shielded by the upper surface 31 of the outer casing. The corner R can be formed into a rounded shape that protrudes rearward.

[0125] The rear portion 42 extends downward from the rear end of the upper portion 41. Furthermore, the rear portion 42 can connect with the back surface of the outer casing 30. Additionally, the corner portion R separates from the corner formed by the encounter between the upper surface 31 and the back surface 34 of the outer casing, thereby forming a predetermined space between the back surface of the flow path member 40 and the rear corner portion of the outer casing 30. This predetermined space can be defined as a washing water supply space, communicating with the connection port 341. Therefore, water supplied from the water supply device 15 to the outer casing 30 can be supplied to the upper portion 41 via the washing water supply space. That is, the washing water ejected from the water supply device 15 and colliding with the corner portion R naturally flows towards the flow path formed in the upper portion 41.

[0126] On the other hand, the aforementioned flow path may include a distribution flow path 43 and a discharge flow path 44. The discharge flow path 44 may supply water supplied from the distribution flow path 43 to the detergent dispenser 50.

[0127] As an example, the aforementioned discharge path 44 may include a first discharge path 45 supplying water to the first receiving section 54, a second discharge path 46 supplying water to the mixing component 60, and a third discharge path 47. The aforementioned distribution path 43 may divert water supplied from the water supply device 15 to the first to third discharge paths 45, 46, and 47.

[0128] In addition, the above-mentioned discharge path 44 may also include a fourth discharge path 48 for supplying water to the second containment section 55.

[0129] In addition, the above-mentioned discharge flow path 44 may also include a fifth discharge flow path 49 for supplying water to the above-mentioned third containment section 56.

[0130] The aforementioned distribution flow path 43 can extend laterally along the rear end of the aforementioned flow path component 40. Furthermore, the aforementioned distribution flow path 43 can distribute water to the aforementioned first discharge flow path 45, second discharge flow path 46, and third discharge flow path 47. Additionally, the aforementioned distribution flow path 43 can also distribute water to the aforementioned fourth discharge flow path 48.

[0131] Specifically, the aforementioned distribution flow path 43 can be formed at the aforementioned corner R. Furthermore, the aforementioned hot water inlet 342 and cold water inlet 343 communicate with the aforementioned distribution flow path 43, thereby allowing hot and cold water to be supplied to the aforementioned distribution flow path 43. The aforementioned hot water inlet 342 and cold water inlet 343 can be positioned off-center from either the left or right edge of the aforementioned distribution flow path 43. The aforementioned hot water inlet 342 and cold water inlet 343 can be positioned closer to the first discharge flow path 45 than the aforementioned second discharge flow path 46.

[0132] Furthermore, the aforementioned distribution flow path 43 may be formed with multiple distribution ribs 430. Through the aforementioned distribution ribs 430, water flowing along the aforementioned distribution flow path 43 is diverted to the aforementioned first to fifth discharge flow paths 45 to 49. In addition, the aforementioned distribution flow path 43 can be understood as a flow path formed between the leftmost distribution rib and the rightmost distribution rib.

[0133] The aforementioned distribution rib 430 may include a guide rib 437 that guides water introduced into the inner side of the flow path component 40 to one side. Based on the lateral direction of the flow path component 40, the hot water inlet 342 and the cold water inlet 343 may be positioned off-center. Figure 12 The location is on the right side of the above-mentioned flow distribution path 43. In particular, the above-mentioned cold water inlet 343 can be located at the right end of the above-mentioned flow distribution path 43.

[0134] Therefore, the guide rib 437 can be formed on the edge of the distribution flow path 43 corresponding to the location of the cold water inlet 343. The guide rib 437 can be formed with rounded corners or inclined with a predetermined curvature so as to guide the water supplied from the cold water inlet 343 to the left edge side of the distribution flow path 43.

[0135] As an example, the aforementioned guide rib 437 extends forward from the rear end of the aforementioned distribution flow path 43, and can be formed with rounded corners or angled toward the left edge of the aforementioned flow path component 40.

[0136] The aforementioned distribution rib 430 may further include a first distribution rib 431 that guides the flow of hot and cold water. The aforementioned first distribution rib 431 may have a rounded corner with a predetermined curvature at the point where it separates from the aforementioned guide rib 437 toward the left edge of the flow path component 40.

[0137] Specifically, the first distribution rib 431 extends forward with rounded corners from the rear end of the distribution flow path 43, i.e., the rear end of the flow path component 40. Furthermore, the rear end of the first distribution rib 431 can be located between the hot water inlet 342 and the cold water inlet 343. Additionally, the first distribution rib 431 extends forward with rounded corners towards the first discharge flow path 45 and the second discharge flow path 46. Therefore, water discharged from the hot water inlet 342 can be guided to the first and second discharge flow paths 45 and 46 via the first distribution rib 431. Furthermore, water discharged from the first cold water inlet 34a can be guided to the first and second discharge flow paths 45 and 46 via the first distribution rib 431 and the guide rib 437.

[0138] The first distribution rib 431 can extend to the vicinity of the inlet of the fourth discharge flow path 48. Therefore, hot and cold water can be guided along the first distribution rib 431. Furthermore, at least a portion of the supplied hot and cold water can be mixed at the end of the first distribution rib 431 and then guided to the fourth discharge flow path 48. Additionally, the remaining portion of the supplied hot and cold water can be supplied to the first to third discharge flow paths 45, 46, and 47 formed at a point separating them from the fourth discharge flow path 48 to the left.

[0139] Additionally, the rear end side of the aforementioned first distribution rib 431 ( Figure 12An auxiliary rib 436 extends horizontally to the side of the right side of the flow path component 40. This auxiliary rib 436 can extend toward the cold water inlet 343, specifically toward the first cold water inlet 343a. Furthermore, the auxiliary rib 436 can extend from a point where it separates from the upper end of the first distribution rib 431 downwards. Additionally, the front end of the auxiliary rib 436 can extend forward to connect with the corner R. By forming the auxiliary rib 436, cold water flowing in from the rear of the flow path component 40 is prevented from excessively bypassing downwards, allowing the cold water to flow along the first distribution rib 431 toward the plurality of flow paths 45-48 constituting the discharge flow path 44.

[0140] The aforementioned distribution rib 430 may include a second distribution rib 432 that guides the flow of hot and cold water passing through the aforementioned first distribution rib 431. The aforementioned second distribution rib 432 may extend linearly for a predetermined length from a point separating from the end of the aforementioned first distribution rib 431 toward the left end of the aforementioned flow path component 40.

[0141] Furthermore, the second distribution rib 432 can extend upwards from the corner R to a predetermined height. Additionally, the second distribution rib 432 can be located at a point that separates rearwards from the end of the first distribution rib 431. Therefore, hot water discharged from the hot water outlet 342 flows along the left side of the first distribution rib 431 and then branches to the front and back surfaces of the second distribution rib 432.

[0142] The second distribution rib 432 extends linearly in the left-right direction to maintain the straight-line flow of cold and hot water via the first distribution rib 431. Furthermore, it can be designed such that, based on the front-back separation distance between the second distribution rib 432 and the first distribution rib 431, hot water is diverted in a predetermined ratio in the front-back direction, and hot and cold water flow in an appropriate mixed ratio.

[0143] At this point, the mixing ratio of hot and cold water can be determined based on the distance between the end of the first distribution rib 431 and the second distribution rib 432 in the front-back direction, and the width of the flow path in the front-back direction with the second distribution rib 432 as the reference. The width of the flow path in the front-back direction with the second distribution rib 432 as the reference can be understood as representing the width of the flow path between the back of the outer casing 30 and the second distribution rib 432, and the width between the second distribution rib 432 and the front end of the corner R, i.e., the front end of the washing water supply space.

[0144] The aforementioned distribution rib 430 may further include a third distribution rib 433 for guiding water flowing into the first discharge flow path 45 and the second discharge flow path 46. Specifically, the third distribution rib 433 may extend between the first discharge flow path 45 and the second discharge flow path 46. As an example, the front end of the third distribution rib 433 may be positioned closer to the end of the first discharge flow path 45.

[0145] The aforementioned third distribution rib 433 can extend rearward. In addition, the front half of the aforementioned third distribution rib 433 can be formed into a rounded shape, and the rear half can extend side by side with the aforementioned second distribution rib 432.

[0146] From another perspective, the right end (rear end) of the third distribution rib 433 is located at a point where it separates from the second distribution rib 432 forward, and at a point where it separates from the left end of the second distribution rib 432 to the right, so that the third distribution rib 433 and the second distribution rib 432 can overlap by a predetermined length in the front-rear direction. Furthermore, the third distribution rib 433 extends linearly for a predetermined length in the left direction and then forms a rounded corner forward, so that the left end (front end) of the third distribution rib 433 can connect to the left edge of the inlet of the first distribution flow path 45. Therefore, washing water flowing towards the front of the third distribution rib 433 is guided to the first discharge flow path 45, and washing water flowing towards the rear of the third distribution rib 433 is guided to the second discharge flow path 46.

[0147] At this time, cold water flows through the separation space between the second distribution rib 432 and the third distribution rib 433, mixes with the hot water flowing along the second distribution rib 432, and can then be guided to the second discharge flow path 46. The amount of washing water guided to the second discharge flow path 46 and the mixing ratio of hot and cold water vary depending on the front-to-back separation distance between the second distribution rib 432 and the third distribution rib 433.

[0148] The aforementioned distribution rib 430 may further include a fourth distribution rib 434. The fourth distribution rib 434 is a rib connecting the right end of the inlet of the first discharge flow path 45 and the rear end of the upper part 41, and can be formed to slope forward as it approaches the left side from the right. Specifically, the left and right ends of the inlet of the first discharge flow path 45 can be connected to the third distribution rib 433 and the fourth distribution rib 434, respectively. Therefore, washing water can be guided to the first discharge flow path 45 through the third distribution rib 433 and the fourth distribution rib 434. Furthermore, the flow rate of water distributed to the first discharge flow path 45 and the second discharge flow path 46 can be determined based on the arrangement position and shape of the third distribution rib 433.

[0149] The aforementioned distribution flow path 43 may further include a fifth distribution rib 435. Specifically, the fifth distribution rib 435 extends forward from the rear end of the corner R, and can be positioned between the inlet of the second discharge flow path 46 and the inlet of the third discharge flow path 47. The fifth distribution rib 435 may be formed to extend forward with a rounded corner or at an angle as it approaches the left side. Furthermore, the fifth distribution rib 435 can be understood as a rib extending from the rear end of the corner R to the front end. Therefore, the rear end of the fifth distribution rib 435 is located behind the second distribution rib 432, and may be located at a point where it separates forward from the rear end of the flow path component 40 (or the back side of the housing 30). Therefore, a portion of the washing water flowing to the left side of the flow path component 40 via the second distribution rib 432 and the third distribution rib 433 can be guided to the third discharge flow path 47.

[0150] The left end of the aforementioned distribution flow path 43 can be defined by the left edge of the aforementioned flow path component 40, and the right end can be defined by the fence 438. Specifically, the fence 438 extends from the rear end of the aforementioned flow path component 40 to the front end of the aforementioned corner R, and can be formed at a point that separates from the right end of the aforementioned flow path component 40 to the left.

[0151] Furthermore, the aforementioned fence 438 is connected to the left edge of the inlet of the fifth discharge flow path 49, and the right edge of the inlet of the fifth discharge flow path 49 can be defined by the right side of the flow path component 40. Additionally, the aforementioned second cold water inlet 343b communicates with the inlet of the fifth discharge flow path 49, thereby allowing cold water to be supplied to the fifth discharge flow path 49 independently. That is, the cold water discharged from the aforementioned second cold water inlet 343b can be supplied only to the fifth discharge flow path 49. The flow path connecting the inlet of the fifth discharge flow path 49 to the back of the housing 30 can be defined as an additional distribution flow path different from the aforementioned distribution flow path 43.

[0152] On the other hand, the inlet (or rear end) of the discharge flow path 44 is connected to the front end of the distribution flow path 43 and can extend forward by a predetermined length. The discharge flow path 44 can be formed by recessing a predetermined depth downward from the upper surface of the upper part 41 or by forming a step. In addition, the upper surface of the remaining upper part 41, excluding the discharge flow path 44, contacts the bottom of the upper surface 31 of the housing. Therefore, by combining the housing 30 with the flow path component 40, the upper surface of the discharge flow path 44 is shielded, thereby completing the flow path.

[0153] When viewed from above the first receiving section 54, the first to third discharge paths 45, 46, and 47 are arranged within the space defining the first receiving section 54, and are configured to supply washing water to the first receiving section 54.

[0154] Specifically, the first discharge flow path 45 extends forward from the front end of the distribution flow path 43 toward the blades of the mixing component 60. That is, the first discharge flow path 45 can extend toward a point that is separated to the right from the axial radius of the rotation center of the mixing component 60. In addition, an open nozzle 451 can be formed at the lower end of the front surface of the first discharge flow path 45. The nozzle 451 can open toward the surface of the blade 62, and the shape of the opening of the nozzle 451 can be designed in various shapes.

[0155] On the other hand, the lower surface of the first discharge flow path 45 can extend downwards at an angle towards the front end. Furthermore, the nozzle 451 can be opened at the lower end of the front surface of the first discharge flow path 45. Therefore, the water sprayed from the nozzle 451 tilts downwards and impacts the surface of the blade 62, causing the mixing component 60 to rotate. As an example, the inclination angle of the bottom of the first discharge flow path 45 can be designed such that the washing water sprayed from the nozzle 451 intersects the surface of the blade 62 perpendicularly. The nozzle 451 can be defined as the first nozzle 451.

[0156] Furthermore, the first discharge path 45 is located at a point radially separated from the rotation axis 61 of the mixing component 60. The torque generated by the washing water ejected from the nozzle 451 causes the mixing component 60 to rotate. Therefore, the further away the point where the water ejected from the first nozzle 451 strikes the blade surface of the mixing component 60 is from the rotation axis 61, the faster the mixing component 60 rotates. Therefore, the extension position of the first nozzle 451 can be appropriately designed based on the rotation speed of the mixing component 60, which optimizes the mixing of washing water and detergent.

[0157] The first discharge flow path 45 provides only a flow rate sufficient to rotate the mixing component 60 at a predetermined speed, so the width of the first discharge flow path 45 can be designed to be narrower than the width of the second discharge flow path 46.

[0158] The second discharge flow path 46 extends forward from the distribution flow path 43 and can extend through the center of the first receiving portion 54. Furthermore, the left edge of the second discharge flow path 46 can extend forward from the end of the fifth distribution rib 435. Additionally, the second discharge flow path 46 can extend to the front end of the first receiving portion 54. Furthermore, the second discharge flow path 46 can extend to the front end of the flow path member 40. The first receiving portion 54 can be defined as the portion where the circumferential surface of the mixing member 60 is rounded. The recessed portion at the upper end of the front surface of the first receiving portion 54 can be understood as a guide portion formed to collect splashed washing water in the first receiving portion 54.

[0159] The second discharge path 46 can be configured such that water for dissolving the powdered detergent filled inside the first receiving portion 54 and rinsing off detergent adhering to the surface of the first receiving portion 54 falls from the upper side of the first receiving portion 54. For this purpose, the second discharge path 46 can have a plurality of rinsing holes 463. The rinsing holes 463 are evenly arranged within the first receiving portion 54, thereby minimizing the presence of powdered detergent residue inside the first receiving portion 54. The rinsing holes 463 can be defined as first rinsing holes 463 to distinguish them from the second rinsing hole 481 and the third rinsing hole 491 described later.

[0160] Furthermore, the aforementioned second discharge path 46 may include a main flow path 461 extending forward from the aforementioned distribution path 43 and expansion sections 462 extending to both sides from the front end of the aforementioned main flow path 461. That is, the aforementioned main flow path 461 may be designed in a shape corresponding to the main body of the arrow, and the aforementioned expansion sections 462 may be designed in a shape corresponding to the head of the arrow.

[0161] Furthermore, multiple first flushing holes 463 may be formed along the main flow path 461 and the expansion portion 462. The first flushing holes 463 may be formed to penetrate the flow path member 40 in the vertical direction. Alternatively, the first flushing holes 463 may be formed in a nozzle-shaped flushing portion 466 protruding downwards from the lower surface of the flow path member 40. However, depending on the shape of the flushing portion 466 or the configuration of the first flushing holes 463, the first flushing holes 463 may also penetrate the flow path member 40 at a downward angle, rather than penetrating vertically downwards.

[0162] The main flow path 461 extends from the distribution flow path 43 and can extend further forward through the center of the mixing component 60. Additionally, the expansion portion 462 extends from the front end of the main flow path 461 to the front surface edge of the flow path component 40, and can extend to the left and right sides based on the main flow path 461. At least a portion of the edge of the expansion portion 462 can be rounded with a curvature corresponding to the curvature of the front surface edge of the first receiving portion 54. The first flushing hole 463 can be formed in both the main flow path 461 and the expansion portion 462.

[0163] Additionally, the first flushing hole 463 may include a main flushing hole 464 formed in the main flow section 461 and an expansion flushing hole 465 formed in the expansion section 462. Multiple main flushing holes 464 may be formed and may be positioned to overlap with the mixing component 60 when viewed from above.

[0164] As an example, the main flushing hole 464 can be formed on a vertical line through the rotating shaft 61 of the mixing component 60. Therefore, the washing water passing through the main flushing hole 464 can fall to the tip of the rotating shaft 61 and flow along its surface, simultaneously washing away any powdered detergent adhering to the rotating shaft 61. Alternatively, the main flushing hole 464 can also be formed on the upper side of the blades 62 of the mixing component 60. Therefore, the washing water falling from the main flushing hole 464 can rinse away any powdered detergent adhering to the surface of the blades 62.

[0165] Multiple expansion flushing holes 465 can be separately arranged along the front end of the expansion portion 462. Furthermore, when viewed from above, the expansion flushing holes 465 can be located directly above the rounded front surface of the first receiving portion 54. For example, since the front surface of the first receiving portion 54 has rounded corners, the multiple expansion flushing holes 465 can also be arranged on a virtual arc extending along the front surface of the first receiving portion 54. Additionally, one or more expansion flushing holes 465 can be further formed at points corresponding to the edge of the blade 62 and the rotation axis 61. In this case, the positions of the expansion flushing holes 465 can be formed at points corresponding to the ring 63 of the mixing component 60. Therefore, water falling from the main flushing hole 464 can wash away the powdered detergent adhering to the blade 62, especially to the ring 63.

[0166] The third discharge path 47, used for washing powdered detergent adhering to the surface of the blade 62, can be disposed to the side of the second discharge path 46. Furthermore, based on the second discharge path 46, the first discharge path 45 and the third discharge path 47 can be disposed side-by-side on opposite sides of each other. The surface (back side) of the blade 62 impacted by the washing water discharged from the third discharge path 47 can be understood as the opposite surface (front surface) of the blade 62 impacted by the washing water sprayed from the nozzle 451 of the first discharge path 45.

[0167] The aforementioned third discharge flow path 47 can extend forward from the aforementioned distribution flow path 43. The aforementioned third discharge flow path 47 can be recessed in the aforementioned upper portion 41. In addition, the aforementioned third discharge flow path 47 can extend to a position where, when viewed from above, it overlaps with at least a portion of the aforementioned mixing component 60 in the vertical direction. Similar to the aforementioned first discharge flow path 45, the aforementioned third discharge flow path 47 can be formed such that its bottom slopes downward as it approaches the front.

[0168] A second nozzle 471 may be formed at the lower end of the front surface of the third discharge flow path 47, spraying water in a direction opposite to the rotation direction of the mixing component 60. The second nozzle 471 may be formed at the lower end of the third discharge flow path 47. In addition, the water sprayed from the second nozzle 471 is directed toward the back of the blade 62.

[0169] Furthermore, the width of the third discharge flow path 47 is smaller than the width of the first discharge flow path 45, resulting in a lower flow rate in the third discharge flow path 47. Therefore, it is possible to prevent the mixing component 60 from rotating in reverse or stopping due to water ejected from the second nozzle 471. Additionally, the second nozzle 471 can be located behind the first nozzle 451. That is, the first discharge flow path 45 can extend in front of the third discharge flow path 47.

[0170] Furthermore, the interval between the left side of the third discharge flow path 47 and the second discharge flow path 46 can be designed to be smaller than the interval between the right side of the first discharge flow path 45 and the second discharge flow path 46. From another perspective, this can be interpreted as the distance between the third discharge flow path 47 and the rotation axis of the mixing component 60 being designed to be smaller than the distance between the first discharge flow path 45 and the rotation axis of the mixing component 60.

[0171] In detail, the reverse rotational torque M2 of the washing water ejected from the second nozzle 471 acts on the mixing component 60 in the opposite direction to the forward rotational torque M1 of the washing water ejected from the first nozzle 451. Therefore, by making the resulting reverse rotational torque M2 smaller than the forward rotational torque M1, the obstruction to the forward rotation of the mixing component 60 can be minimized.

[0172] On the other hand, the fourth discharge path 48 can be located above the second receiving portion 55. The fourth discharge path 48 can extend forward from the distribution path 43. The fourth discharge path 48 can be formed in front of the first distribution rib 431, and the inlet of the fourth discharge path 48 can be formed at a position separated forward from the front end of the first distribution rib 431. More specifically, the front end of the first distribution rib 431 can be located between the left and right edges of the fourth discharge path 48. Furthermore, the fourth discharge path 48 can extend further forward via the center of the second receiving portion 55.

[0173] The aforementioned fourth discharge passage 48 may be recessed downward from the aforementioned upper portion 41. Furthermore, the aforementioned fourth discharge passage 48 may have a plurality of second flushing holes 481. These second flushing holes 481 are formed by openings through the aforementioned fourth discharge passage 48, and can be configured such that water supplied to the aforementioned fourth discharge passage 48 falls downward.

[0174] The aforementioned second flushing hole 481 may include a plurality of first front holes 482 and a plurality of first rear holes 483. The first front holes 482 may be formed at positions corresponding to the first front cover holes 571 of the receiving cover 57 placed in the second receiving portion 55. The first rear holes 483 may be formed at positions corresponding to the first rear cover holes 572 of the receiving cover 57. Therefore, the first rear holes 483 may be located behind the first front holes 482.

[0175] The fifth discharge flow path 49 can be located above the third receiving section 56. The fifth discharge flow path 49 extends forward from the distribution flow path 43. The fifth discharge flow path 49 communicates with an additional distribution flow path formed between the fence 438 and the right side of the flow path member 40, and the width of the fifth discharge flow path 49 can be greater than the width of the additional distribution flow path. That is, the right side of the fifth discharge flow path 49 is defined by the right side of the flow path member 40, and the left side of the fifth discharge flow path 49 can be formed at a point separating it from the fence 438 to the left.

[0176] The additional distribution flow path is positioned in front of the second cold water inlet 343b, supplying the washing water flowing in from the second cold water inlet 343b to the fifth discharge flow path 49. Furthermore, the fifth discharge flow path 49 can extend further forward from the center of the third receiving section 56.

[0177] The aforementioned fifth discharge flow path 49 can be recessed downward from the aforementioned upper part 41. Furthermore, the aforementioned fifth discharge flow path 49 can be formed with a plurality of third flushing holes 491. The aforementioned third flushing holes 491 are formed by openings through the aforementioned fifth discharge flow path 49, and can be configured so that water supplied to the aforementioned fifth discharge flow path 49 falls downward.

[0178] The third flushing hole 491 may include a plurality of second front holes 492 and a plurality of second rear holes 493. The number of second front holes 492 is greater than the number of second rear holes 493, thereby allowing more water to be supplied to the rear side compared to the front side of the third receiving portion 56.

[0179] The second front hole 492 can be formed at a position corresponding to the second front cover hole 575 of the receiving cover 57 disposed on the third receiving portion 56. The second rear hole 493 can be formed at a position corresponding to the second rear cover hole 576 of the receiving cover 57. Therefore, the second rear hole 493 is located behind the second front hole 492.

[0180] On the other hand, the rear side of the aforementioned rear portion 42 may be recessed to form a plurality of drainage portions 421. These drainage portions 421, designed to prevent backflow of water supplied to the interior of the housing 30, are recessed forward from the rear side of the rear portion 42 and can extend from the upper end to the lower end of the rear portion 42. Furthermore, the plurality of drainage portions 421 can be arranged separately in the width direction of the rear portion 42. Therefore, when the water pressure supplied from the water supply device 15 is high, a portion of the supplied water flows downwards through the drainage portions 421 towards the rear side of the housing 30. Through the plurality of drainage portions 421, even if the water pressure supplied from the water supply device 15 suddenly increases, backflow of water into the water supply device 15 or the water supply pipe connection 152, thus preventing leakage, can be prevented.

[0181] Side guides 412 may be formed at both ends of the aforementioned flow path component 40. The side guides 412 may extend rearward from the front end of the flow path component 40 by a predetermined width along the side edge of the flow path component 40. Furthermore, a side limiting portion 413 may protrude downward from the bottom of the side guide 412. The side limiting portion 413 protrudes downward from the front end of the side guide 412, thereby maximally extending the detergent dispenser 50. The side limiting portion 413 interacts with the limiting protrusion 514 formed on the detergent dispenser 50 (see reference 514). Figure 17 This creates interference and can prevent the detergent box 50 from falling off.

[0182] With the flow path component 40 installed on the housing 30, the side guide 412 can be positioned above the housing guide 332. Furthermore, with the detergent dispenser 50 inserted, the detergent dispenser guide 513 can be positioned between the housing guide 332 and the side guide 412.

[0183] Furthermore, the bottom of the aforementioned side guide 412 can contact the upper end of the limiting protrusion 514 of the aforementioned detergent dispenser guide 513. Additionally, when the detergent dispenser 50 is pulled out to its maximum extent, the upper end of the limiting protrusion 514 hooks onto the aforementioned side limiting portion 413, preventing the front end of the detergent dispenser 50 from drooping downwards.

[0184] On the other hand, sidewalls 411 may be formed at both ends of the flow path component 40 corresponding to the bottom of the side guide 412. The sidewalls 411 extend downward from the outermost edge of the bottom of the side guide 412 and extend rearward for a predetermined length, so that they contact the side of the housing 30 when the flow path component 40 is installed on the housing 30. Therefore, the detergent dispenser guide 513 is placed between the lower end of the sidewall 411 and the upper surface of the housing guide 332.

[0185] In detail, the detergent dispenser 50 may include a detergent dispenser body 51 having the aforementioned receiving portion 53 and a detergent dispenser handle 52 formed on the front surface of the detergent dispenser body 51. The detergent dispenser handle 52 may be configured to cover the frame opening 121 when the detergent dispenser 50 is pushed in. Furthermore, by inserting a finger into the grip groove 520 formed between the back of the detergent dispenser handle 52 and the front surface of the detergent dispenser body 51 and pulling the detergent dispenser handle 52 forward, the detergent dispenser 50 can be pulled out.

[0186] The detergent dispenser 50 described above will now be described in more detail with reference to the accompanying drawings.

[0187] Figure 17 This is a top-down perspective view of the detergent dispenser, mixing components, and housing cover in a disassembled state. Figure 18 This is a perspective view of the detergent dispenser, mixing components, and housing cover as viewed from below, showing them disassembled. Figure 19 This is a three-dimensional view of the aforementioned hybrid components.

[0188] Reference Figures 17 to 19 The detergent dispenser 50 is configured as a drawer with an opening on the upper surface, and can be inserted into the receiving space of the outer casing 30 or pulled forward from the receiving space.

[0189] Specifically, the upper surface of the detergent dispenser body 51 may be recessed to form the receiving portion 53. The receiving portion 53 may include the first receiving portion 54 for mounting the mixing component 60. In addition, the receiving portion 53 may also include a second receiving portion 55 and a third receiving portion 56 arranged side by side on the side of the first receiving portion 54.

[0190] The upper surface and back surface of the first receiving portion 54 are open, and the mixing component 60 can be received inside. In addition, a rotating boss 541 is formed on the bottom of the first receiving portion 54 so as to rotatably mount the mixing component 60. Therefore, the mixing component 60 can rotate within the first receiving portion 54 about the rotating boss 541 as the central axis.

[0191] The front surface of the first receiving portion 54 is formed with rounded corners. Specifically, the rounded corners are formed with a radius of curvature slightly larger than the radius of rotation of the mixing component 60, so that there is no interference with the mixing component 60 when it rotates. Therefore, after the mixing component 60 is received in the first receiving portion 54, the edge of the mixing component 60 is adjacent to the inner surface of the first receiving portion 54 to a degree that they do not contact each other.

[0192] Furthermore, the two sides of the first receiving portion 54 extend parallel to each other. Therefore, the dissolved powder detergent and water inside the first receiving portion 54 can be smoothly discharged to the back side of the opening of the first receiving portion 54.

[0193] Furthermore, a rear plate 542 may be formed on the back side of the opening of the first receiving portion 54. The rear plate 542 may extend horizontally, connecting the rear ends of both sides of the first receiving portion 54 at a point separating it from the bottom of the first receiving portion 54 upwards. The rear plate 542 prevents the powder detergent inside the first receiving portion 54 from being discharged all at once. Additionally, the rear plate 542 prevents the mixing component 60 from detaching from the outside of the first receiving portion 54. The rear plate 542 may be formed at a point closer to the bottom than the upper surface of the first receiving portion 54.

[0194] Additionally, one or more drainage channels 543 extending rearward may be formed at the bottom of the first receiving portion 54. The drainage channels 543 allow for easy discharge of powdered detergent and water from inside the first receiving portion 54.

[0195] The mixing component 60 is configured in a fan shape and, while rotating inside the first receiving portion 54, can mix the powdered detergent and washing water introduced into the first receiving portion 54. The mixing component 60 may include a rotating shaft 61 (or hub) mounted on the rotating boss 541 and a plurality of blades 62 extending from the rotating shaft 61. The mixing component 60 may be named a mixing fan, propeller, or screw.

[0196] The aforementioned rotating shaft 61 is formed at the center of the aforementioned mixing component 60, and can serve as the rotation center of the aforementioned mixing component 60. Furthermore, the lower surface of the aforementioned rotating shaft 61 is open, allowing the aforementioned rotating boss 541 to be inserted into the interior of the aforementioned rotating shaft 61. The aforementioned rotating boss 541 rotatably supports the aforementioned rotating shaft 61 within the aforementioned rotating shaft 61.

[0197] The blade 62 is formed with an angle of less than 90 degrees relative to the bottom surface of the receiving portion 53, and the upper end of the blade 62 is positioned at a point deviating from the rotational direction of the blade 62 relative to the vertical plane passing through the lower end of the blade 62. That is, the blade 62 can be formed to tilt towards the rotational direction of the mixing member 60 as it approaches the upper end from the lower end. Therefore, when the mixing member 60 rotates, the powdered detergent at the bottom of the first receiving portion 54 can be effectively mixed.

[0198] Furthermore, the blade 62 can be tilted so as to be orthogonal to the extension line of the first nozzle 451. Therefore, when water jetted from the first nozzle 451 impacts the front surface of the blade 62 perpendicularly, the blade 62 can be rotated.

[0199] Additionally, the mixing component 60 may include a ring 63. The ring 63 is circular and may be formed at the edge of the mixing component 60. The ring 63 may connect to the ends of the plurality of blades 62. The ring 63 serves to minimize sloshing and stably maintain the rotational state when the mixing component 60 rotates. Furthermore, it may guide the powdered detergent mixed between the plurality of blades 62 to collect inside the ring 63.

[0200] Furthermore, an auxiliary wing 64 may be formed at the end of the blade 62. The auxiliary wing 64 can extend from the end of the blade 62 along the ring 63. Therefore, water and powdered detergent flowing along the blade 62 will not splash outside the mixing component 60, but can be guided to the inside of the mixing component 60 for mixing.

[0201] The detergent dispenser body 51 may also include a second receiving section 55 and a third receiving section 56. The second receiving section 55 and the third receiving section 56 may be arranged side by side to the side of the first receiving section 54. The second receiving section 55 and the third receiving section 56 may have the same shape, but different positions.

[0202] The following description is based on the shape of the second containment section 55, and the detailed description of the third containment section 56 is omitted. Needless to say, the second containment section 55 or the third containment section 56 can be omitted as needed.

[0203] The upper surface of the second receiving portion 55 may be open and recessed downwards. Furthermore, the upper surface of the opening of the second receiving portion 55 may be quadrilateral in shape. Additionally, the bottom of the second receiving portion 55 may be sloped downwards towards the rear end. Furthermore, a siphon boss 551 protruding upwards may be formed on the rear side of the bottom of the second receiving portion 55. A hollow portion 552 penetrating vertically through the siphon boss 551 is formed inside the siphon boss 551, allowing washing water containing detergent added to the second receiving portion 55 to drain below the detergent dispenser 50. Furthermore, a siphon recess 553 may be formed at the lower edge of the siphon boss 551.

[0204] Additionally, the detergent dispenser 50 may also include a cover 57 placed in the second receiving section 55. The cover 57 may be configured as a single cover that simultaneously covers both the second receiving section 55 and the third receiving section 56, or it may be configured as two separate covers.

[0205] The edge of the aforementioned receiving cover 57 can be placed on a stepped portion 511 that forms a height difference along the upper surface edges of the second receiving portion 55 and the third receiving portion 56. Furthermore, a siphon extension portion 573 extends downward from the bottom of the aforementioned receiving cover 57. The siphon extension portion 573 is configured as a barrel shape with an opening 574 on its lower surface. When the receiving cover 57 is placed in the second receiving portion 55, the siphon boss 551 can be inserted into the siphon extension portion 573.

[0206] Furthermore, the lower end of the aforementioned siphon extension 537 can be placed within the aforementioned siphon recess 553. In this case, the lower end of the aforementioned siphon extension 573 is located below the bottom surface of the aforementioned second receiving portion 55, separate from the bottom surface of the aforementioned siphon recess 553. In other words, the lower end of the aforementioned siphon extension 573 can be located between the bottom of the aforementioned second receiving portion and the bottom of the aforementioned siphon recess 553. Therefore, when water and detergent are supplied to the aforementioned second receiving portion 55, the detergent mixture flows upwards along the space formed between the outer peripheral surface of the aforementioned siphon boss 551 and the inner peripheral surface of the aforementioned siphon extension 537. Additionally, when the water level reaches the upper surface of the aforementioned siphon boss 551, it can be discharged downwards into the aforementioned detergent container 50 through the aforementioned hollow 552 via siphon action.

[0207] On the other hand, a first front cover hole 571 and a first rear cover hole 572 may be formed in the aforementioned receiving cover 57. The periphery of the aforementioned first front cover hole 571 may be formed to be inclined to guide water falling from the upper second flushing hole 481 through the aforementioned first front cover hole 571.

[0208] The first rear cover hole 572 can be formed behind the first front cover hole 571. Alternatively, the first front cover hole 571 can be formed in front of the siphon extension 573, and the first rear cover hole 572 can be formed behind the siphon extension 573. The first rear cover hole 572 can be recessed forward from the rear end of the receiving cover 57, forming a through hole through the rear edge of the first receiving portion 55 when the receiving cover 57 is placed in the detergent dispenser 50. Furthermore, the through hole is located directly below the second rinsing hole 481, and the washing water falling from the second rinsing hole 481 fills the interior of the second receiving portion 55 after passing through the through hole.

[0209] On the other hand, when viewed from above, at least a portion of the first rear cover hole 572 overlaps with the siphon recess 553. Therefore, a portion of the washing water flowing through the first rear cover hole 572 falls directly into the siphon recess 553.

[0210] On the other hand, the third receiving portion 56 may have the same structure and shape as the second receiving portion 55. That is, the third receiving portion 56 may have a siphon boss 561 with a hollow center 562 and a siphon recess 563. Furthermore, the receiving portion cover 57 may cover the third receiving portion 56. The receiving portion cover 57 may have a siphon extension 577 for inserting the siphon boss 561. Additionally, the receiving portion cover 57 may have a second front cover hole 575 and a second rear cover hole 576. The structure and shape of the second front cover hole 575 and the second rear cover hole 576 may be the same as the first front cover hole 571 and the first rear cover hole 572.

[0211] Furthermore, a hook portion 512 may be formed on the upper surface of the detergent dispenser body 51. The hook portion 512 protrudes from the upper surface of the detergent dispenser body 51 and may be configured as a hook shape capable of elastic deformation. Additionally, when the detergent dispenser 50 is pulled out to its maximum extent, the hook portion 512 is engaged with and restrained by the outer casing 30 or the flow path component 40, preventing the detergent dispenser 50 from separating. Undoubtedly, the user can also pull the detergent dispenser 50 with a force exceeding the elasticity of the hook portion 512 to separate the detergent dispenser 50 from the outer casing 30.

[0212] Furthermore, detergent dispenser guides 513 can extend considerably in the front-to-back direction on both the left and right sides of the detergent dispenser body 51. These guides 513 can extend from the detergent dispenser handle 52 to the rear end of the detergent dispenser body 51. Additionally, the detergent dispenser guides 513 are positioned on the outer casing guide 332, thereby guiding the sliding of the detergent dispenser 50 in and out.

[0213] The rear end of the aforementioned detergent dispenser guide 513 may have an upwardly protruding limiting protrusion 514. When the detergent dispenser 50 is pulled out to its maximum extent, the limiting protrusion 514 is engaged with and limited by the detergent dispenser limiting portion 333, thereby preventing the detergent dispenser 50 from separating.

[0214] The water flow state of the detergent supply device 20 having the structure described above will now be described in detail with reference to the accompanying drawings.

[0215] Figure 20 This is a schematic diagram of the flow path of washing water supplied to the detergent supply device. Figure 21 This is a schematic diagram of the flow state of washing water in the distribution path of the aforementioned detergent supply device. Figure 22 This is a schematic diagram showing the configuration of the water supply inlets connected to the various compartments of the detergent dispenser.

[0216] Reference Figures 20 to 22 Based on the operation of the water supply device 15, water is supplied to the interior of the outer casing 30. That is, by selectively operating the hot water valve 153 and the cold water valve 154, water can be supplied to the hot water inlet 342 and the cold water inlet 343. At this time, the cold water supplied from the second cold water inlet 343b can be directly supplied to the fifth discharge flow path 49 via the additional distribution flow path, thereby supplying the third receiving section.

[0217] Water supplied from the hot water inlet 342 and the first cold water inlet 343a flows into the distribution flow path 43. The hot water flowing in through the hot water inlet 342 and the cold water flowing in through the first cold water inlet 343a mix in the distribution flow path 43 and flow along the distribution flow path 43, while being guided to the discharge flow path 44.

[0218] In detail, the cold water supplied through the first cold water inlet 343a can be guided to the side via the guide rib 437. Figure 21 (Left side of the middle). At this time, a portion of the cold water supplied through the first cold water inlet 343a flows downward along the back of the outer casing 30, while the remaining portion is guided by the auxiliary rib 436 to flow along the distribution flow path 43. In addition, the cold water guided by the auxiliary rib 436 flows through a flow path formed along the front surface of the first distribution rib 431.

[0219] In addition, the hot water supplied through the hot water inlet 342 can be guided to the side along the back of the first distribution rib 431. Figure 21 (Left side of the middle). The hot and cold water can be mixed at the end of the first distribution rib 431, and a portion of the mixed hot and cold water is guided to the fourth discharge flow path 48 so that it can be supplied to the second receiving part 55.

[0220] The remaining portion of the mixed hot and cold water separates at the end of the second distribution rib 432 and can move laterally along the front and back surfaces of the second distribution rib 432. Meanwhile, the washing water moving along the front of the second distribution rib 432 flows into the first discharge path 45 through the third distribution rib 433 and the fourth distribution rib 434, and can be supplied to the first receiving portion 54 via the first discharge path 45. The washing water flowing along the first discharge path 45 is sprayed from the first nozzle 451 and collides with the front surface of the blade 62, causing the mixing component 60 to rotate.

[0221] Furthermore, the washing water moving behind the second distribution rib 432 is supplied to the first receiving portion 54 via the third distribution rib 433 and the fifth distribution rib 435, and through the second discharge flow path 46. Water supplied through the second discharge flow path 46 can be supplied to the inner surface of the first receiving portion 54 through the first flushing hole 463. Additionally, water can also be supplied to the mixing component 60 through the first flushing hole 463.

[0222] On the other hand, when passing through the left end of the second distribution rib 432, the hot water and cold water in front of and behind the second distribution rib 432 can mix again, and the mixed water can flow into the second discharge path 46 through the third distribution rib 433 and the fifth distribution rib 435.

[0223] A portion of the washing water flowing behind the second distribution rib 432 flows into the third discharge path 47 via the space between the fifth distribution rib 435 and the back surface of the outer casing 30, and can be supplied to the first receiving portion 54 through the third discharge path 47. Additionally, the washing water flowing along the third discharge path 47 can wash the back surface of the blade 62 after being sprayed from the second nozzle 471.

[0224] The operation of the washing water supplied from the flow path component 40 to each receiving section 53 will now be described in further detail with reference to the accompanying drawings.

[0225] Figure 23 This is a schematic diagram showing the state of spraying washing water into the mixing component through the nozzle of the flow path component. Figure 24 This is a schematic diagram showing the state of washing water falling into the first receiving part through the first flushing hole of the aforementioned flow path component.

[0226] Reference Figure 23 as well as Figure 24 Water flowing along the first discharge flow path 45 flows along the downwardly sloping bottom boundary surface of the first discharge flow path 45 and is sprayed onto the front surface of the blade 62 through the first nozzle 451 formed at the lower end of the front surface of the first discharge flow path 45.

[0227] The bottom of the first discharge path 45 can extend obliquely in a direction intersecting with one side of the blade 62, i.e., the front surface. Therefore, the water sprayed from the first nozzle 451 can impact the front surface of the blade, causing the mixing component 60 to rotate. The angle α formed by the washing water sprayed from the first nozzle 451 and the front surface of the blade 62, i.e., the spray angle of the washing water sprayed from the first nozzle 451, is 90 degrees, thereby maximizing the rotational force of the mixing component 60.

[0228] Furthermore, compared to the rotation axis 61 which is close to the mixing component 60, the rotational torque of the mixing component 60 increases when the first nozzle 451 approaches the edge of the blade 62. Therefore, the formation position of the first discharge path 45 can be appropriately selected according to the design conditions.

[0229] Furthermore, during the spraying of water from the first nozzle 451, the mixing component 60 can continuously rotate. At this time, the first receiving portion 54 is filled with powdered detergent. When the mixing component 60 rotates, the powdered detergent and water mix, causing the powdered detergent to dissolve in the washing water. The mixing component 60 can pulverize unevenly distributed powdered detergent or lumpy powdered detergent in the first receiving portion 54, dissolve it in water, and discharge it to the rear of the detergent container 50.

[0230] In addition, the dissolved detergent discharged to the rear of the detergent box 50 can be discharged into the bucket 11 through the outer shell outlet 321 on the lower surface 32 of the outer shell and the front end of the lower surface 32 of the outer shell.

[0231] In addition, such as Figure 22 as well as Figure 24 As shown, the washing water flowing along the second discharge flow path 46 flows to the expansion section 462 after passing through the main flow path 461. In addition, the washing water falling into the first receiving section 54 through the first flushing hole 463 of the second discharge flow path 46 can wash the interior of the first receiving section 54 and the mixing component 60.

[0232] Specifically, a portion of the washing water flowing through the main flow path 461 can be supplied to the mixing component 60 after falling downwards through the multiple main flush holes 464. The mixing component 60 can be washed by the water falling from the main flush holes 464.

[0233] A portion of the aforementioned main flushing holes 464 may be located directly above the aforementioned rotating shaft 61. Therefore, water falling from the aforementioned main flushing holes 464 can wash away detergent adhering to the surface of the aforementioned rotating shaft 61. Additionally, another portion of the plurality of aforementioned main flushing holes 464 may be located directly above the aforementioned blade 62. Therefore, water falling from the aforementioned main flushing holes 464 can wash away detergent adhering to the aforementioned blade 62.

[0234] Washing water flowing into the expansion section 462 after passing through the main flow channel 461 fills the expansion section 462 and falls downward through the plurality of expansion flushing holes 465, thereby washing the first receiving section 54. Specifically, the expansion flushing holes 465 can be located directly above the front surface of the first receiving section 54 where the corners are formed. In particular, the expansion flushing holes 465 can be arranged along the front end of the first receiving section 54.

[0235] Therefore, the washing water falling from the expansion flushing hole 465 can fall onto the upper end of the front surface portion of the first receiving portion 54 or onto the surface forming the front surface of the first receiving portion 54. Furthermore, the washing water falling from the expansion flushing hole 465 flows along the front surface of the first receiving portion 54 and flows rearward along the inclined bottom surface of the first receiving portion 54. Therefore, detergent adhering to the inner surface of the first receiving portion 54 can be washed away by the washing water falling from the expansion flushing hole 465.

[0236] Additionally, the water used to wash the first receiving section 54 can be discharged along with the detergent into the rear of the detergent box 50. Furthermore, the water and detergent discharged into the rear of the detergent box 50 can be discharged into the bucket 11 through the outer casing outlet 321 on the lower surface 32 of the outer casing and the front end of the lower surface 32 of the outer casing.

[0237] Figure 25 This is a schematic diagram showing the state in which washing water falls into the second receiving section through the second flushing hole formed in the flow path component.

[0238] Reference Figure 22 as well as Figure 25 The water flowing into the fourth discharge flow path 48 flows forward along the fourth discharge flow path 48 and can be supplied to the second receiving part 55 through the second flushing hole 481 formed in the fourth discharge flow path 48.

[0239] As an example, the second receiving section 55 can contain liquid detergent, which, after being diluted in the washing water supplied from the second rinsing hole 481, can be discharged to the bottom of the outer casing 30 through the siphon boss 551.

[0240] Specifically, a portion of the washing water flowing along the fourth discharge path 48 falls downward through the first front hole 482. Then, it falls through the first front cover hole 571 of the receiving cover 57 via the first front cover hole 482 to the front of the second receiving section 55. Additionally, it can mix with liquid detergent inside the second receiving section 55.

[0241] Additionally, another portion of the washing water flowing along the fourth discharge path 48 falls downward through the first rear hole 483. At this time, the washing water falling through the first rear hole 483 falls behind the second receiving section 55 after passing through the first rear cover hole 572 of the receiving section cover 57.

[0242] The first rear hole 483, the first rear cover hole 572, and a portion of the siphon recess 553 can overlap vertically. Therefore, water falling from the first rear hole 483 can pass through the first rear cover hole 572 and directly fall into the siphon recess 553. This dissolves or pulverizes high-viscosity liquid detergent or solid liquid detergent accumulated in the siphon recess 553, facilitating drainage based on the siphon effect.

[0243] Liquid detergent mixed with water supplied to the second receiving section 55 flows from the siphon recess 553 between the siphon extension 573 and the siphon boss 551, into the upper opening of the siphon boss 551, and can then be discharged downwards into the detergent dispenser 50. Additionally, liquid detergent mixed with water discharged downwards into the detergent dispenser 50 can be discharged into the tank 11 via the outer casing outlet 321 on the lower surface 32 of the outer casing and the front end of the lower surface 32 of the outer casing.

[0244] Figure 26 This is a schematic diagram showing the state of washing water falling into the third receiving section through the third flushing hole of the flow path component.

[0245] Reference Figure 22 as well as Figure 26 The water flowing into the fifth discharge flow path 49 flows forward along the fifth discharge flow path 49 and can be supplied to the third receiving part 56 through the third flushing hole 491 formed in the fifth discharge flow path 49.

[0246] As an example, the third receiving section 56 can contain fabric softener, which, after being diluted in the washing water supplied from the third rinsing hole 491, can be discharged downwards through the siphon boss 561.

[0247] Specifically, a portion of the washing water flowing along the fifth discharge path 49 falls downwards from the second front hole 492. At this time, the washing water falling from the second front hole 492 falls through the second front cover hole 575 of the receiving cover 57 into the front of the third receiving section 56. Furthermore, the washing water falling into the third receiving section 56 can mix with fabric softener.

[0248] Additionally, a portion of the remaining washing water flowing along the fifth discharge path 49 falls downwards through the second rear hole 493. At this time, the washing water falling from the second rear hole 493 falls through the second rear cover hole 576 of the receiving cover 57 behind the third receiving section 56.

[0249] The second rear hole 493, the second rear cover hole 576, and a portion of the siphon recess 563 can overlap vertically. Therefore, water falling from the second rear hole 493 can directly flow into the siphon recess 563 through the second rear cover hole 576. This allows for the dissolution or pulverization of highly viscous liquid detergent or solid liquid detergent accumulated in the siphon recess 563, facilitating siphon-based drainage.

[0250] Fabric softener mixed with water supplied to the third receiving section 56 flows from the siphon recess 563 along the space between the siphon extension 577 and the siphon protrusion 561, into the upper opening of the siphon protrusion 561, and can then be discharged downwards into the detergent dispenser 50. Additionally, fabric softener mixed with water discharged downwards into the detergent dispenser 50 can be discharged into the tub 11 via the outer casing outlet 321 on the lower surface 32 of the outer casing and the front end of the lower surface 32 of the outer casing.

[0251] Figure 27 This is a three-dimensional view of the flow path components from the front. Figure 28 This is a top view showing the flow path components of the discharge flow path portion toward the first receiving section of the detergent dispenser. Figure 29 This is a bottom view showing the flow path component of the discharge flow path portion toward the first receiving section.

[0252] Reference Figures 27 to 29 The first discharge path 45 and the third discharge path 47 are formed at positions that cause the mixing component 60 to rotate in opposite directions. Therefore, the position settings of the first discharge path 45 and the third discharge path 47 have a great influence on the mixing performance of the detergent.

[0253] Specifically, the first discharge flow path 45 can be defined as a rotating flow path that generates power to rotate the mixing component 60 for mixing detergent and washing water, and the third discharge flow path 47 can be defined as a washing flow path for rinsing detergent adhering to the back of the blades 62 of the mixing component 60. Furthermore, the first nozzle 451 formed at the end of the first discharge flow path 45 can be defined as a rotating nozzle for rotating the mixing component 60, and the second nozzle 471 formed at the end of the third discharge flow path 47 can be defined as a washing nozzle.

[0254] As described above, in order to maximize the rotational speed by spraying washing water from the first nozzle 451, the blades 62 of the mixing component 60 are formed to be inclined from the vertical direction to the rotational direction. Consequently, the opposite side of the surface impacted by the washing water sprayed from the first nozzle 451, i.e., the back surface of the blades 62, does not come into contact with the washing water, resulting in detergent residue adhering to the back surface of the blades 62 not being properly rinsed off. To solve this problem, the third discharge path 47 is formed to allow the washing water to impact the back surface of the blades 62.

[0255] Furthermore, the third discharge path 47 is formed on the opposite side with respect to the rotation axis 61 of the mixing component 60, so that during the rotation of the mixing component 60 through the rotating nozzle 451, the washing water discharged from the washing nozzle 471 collides with the back of the blade 62.

[0256] In some cases, when the water pressure of the washing water discharged from the washing nozzle 471 is higher than that of the washing water discharged from the rotating nozzle 451, the mixing component 60 fails to rotate. Therefore, it is necessary to minimize the phenomenon that the washing water discharged from the washing nozzle 471 hinders the rotation of the mixing component 60.

[0257] Therefore, the design conditions described below shall apply.

[0258] First, the distance D1 from the center of the rotation axis 61 of the mixing component 60 to the radial direction extending along the line from the direction of the washing water discharged from the rotary nozzle 451 is set to be greater than the distance D2 from the center of the rotation axis 61 to the radial direction extending along the line from the direction of the washing water discharged from the washing nozzle 471.

[0259] From another perspective, this can be interpreted as the shortest distance from the aforementioned rotating shaft 61 to the surface extending through the center of the aforementioned rotating flow path 45 and along the front-back direction of the aforementioned flow path component 40 being longer than the shortest distance from the aforementioned rotating shaft 61 to the surface extending through the center of the aforementioned washing flow path 47 and along the front-back direction of the aforementioned flow path component 40.

[0260] The distance D1 in the radial direction from the aforementioned rotating shaft 61 to the washing water sprayed from the aforementioned rotating nozzle 451 becomes a variable for determining the torque value M1 for forward rotation of the aforementioned mixing component 60. Here, forward rotation refers to rotation along the direction of mixing detergent.

[0261] Conversely, the radial distance D2 from the aforementioned rotation axis 61 to the washing water sprayed from the aforementioned washing nozzle 471 becomes a variable determining the torque value M2 for reversing the aforementioned mixing component 60. Therefore, it can be considered more advantageous if the reversing rotation torque M2 is smaller than the forward rotation torque M1.

[0262] Second, the width W1 of the first discharge flow path 45 is set to be greater than the width W2 of the second discharge flow path 47. From another perspective, this can be interpreted as the opening area, including the width of the first nozzle 451, being larger than the opening area including the width of the second nozzle 471.

[0263] The width or opening area of ​​the plurality of nozzles 451 and 471 becomes a variable determining the amount of washing water discharged from the plurality of nozzles 451 and 471 per unit time, and the amount of washing water discharged per unit time becomes a variable determining the pressure or impact amount acting on the blade 62. Furthermore, the pressure or impact amount acting on the blade 62 becomes a variable determining the rotational torque of the mixing component 60. Therefore, preferably, the width W1 of the first nozzle 451 is designed to be greater than the width of the second nozzle 471, so that the forward rotational torque M1 of the mixing component 60 is greater than the reverse rotational torque M2.

[0264] Third, the front surfaces of the first nozzle 451 and the second nozzle 471 are separated by a predetermined distance D in the front-rear direction of the flow path component 40, specifically, by a predetermined distance D in the front-rear direction of the upper part 41. Furthermore, the front surface of the first nozzle 451 is positioned closer to the surface passing through the center of the rotation axis 61 and parallel to the surface of the first nozzle 451. That is, the distance between the surface passing through the center of the rotation axis 61 and the two parallel surfaces passing through the front surface of the first nozzle 451 can be set to be smaller than the distance between the surface passing through the center of the rotation axis 61 and the two parallel surfaces passing through the front surface of the second nozzle 471.

[0265] The horizontally sprayed washing water falls along a parabolic curve away from the nozzle due to gravity. Therefore, the washing water discharged from the first nozzle 451 maintains a straight-line motion while colliding with the blade 62, and the washing water discharged from the second nozzle 471 falls along a parabolic curve while also colliding with the blade 62, thereby minimizing interference with the rotational motion of the mixing component 60. For this purpose, preferably, the front surface of the second nozzle 471 is positioned behind the front surface of the first nozzle 451.

[0266] Fourth, compared to the first discharge flow path 45, the third discharge flow path 47 is located at a point further away from the hot water outlet 342 or the cold water outlet 343 in the width direction of the flow path component 40. That is, based on the second discharge flow path 46, the first discharge flow path 45 is disposed on one side of the second discharge flow path 46, specifically, at a point corresponding to the point between the hot water outlet 342 and the second discharge flow path 46, while the third discharge flow path 47 is disposed on the other side of the second discharge flow path 46, specifically, based on the second discharge flow path 46, it can be disposed at a point on the opposite side of the first discharge flow path 45.

[0267] Furthermore, only via the rear end of the aforementioned fifth distribution rib 435 ( Figure 28 Washing water from the flow path between the right end of the casing 30 and the back surface of the casing 30 is supplied to the third discharge flow path 47. For this purpose, the inlet of the third discharge flow path 47 may be formed at a point adjacent to the front end of the fifth distribution rib 435 and separated in a direction away from the second distribution flow path 46.

[0268] On the other hand, the blade 62 is formed at an angle in the direction of rotation, so the distance relationship between the rotating nozzle 451 or the washing nozzle 471 and the blade 62 can be explained as follows.

[0269] That is, it can be interpreted that, compared to the second vertical plane which is parallel to the first vertical plane and passes through the upper end of the blade 62 located in front of the rotating nozzle 451, the first vertical plane of the rotating nozzle 451 is closer to the third vertical plane which is parallel to the first vertical plane and passes through the lower end of the blade 62.

[0270] Furthermore, it can be interpreted that the fourth vertical plane, which is via the washing nozzle 471 and parallel to the first to third vertical planes, is closer to the second vertical plane than the third vertical plane, which is via the lower end of the blade located in front of the washing nozzle 471.

[0271] Figure 30 This is a schematic diagram of the flow of washing water discharged from the washing nozzle.

[0272] Reference Figure 30The washing water discharged from the washing nozzle 471 exits through the second nozzle 471 of the third discharge flow path 47 and moves in a straight line along the extension of the bottom slope of the third discharge flow path 47, and then falls along a parabolic curve due to gravity. In addition, during the falling motion, the washing water collides with the back of the blade 62, and thus flows down along the back of the blade 62.

[0273] When viewed from the first discharge path 45 side, the blade 62 extends obliquely from the direction of rotation of the mixing component 60 perpendicular to it. Therefore, when viewed from the third discharge path 47 side, the parabolic trajectory of the washing water is similar to the slope of the back surface of the blade 62. Consequently, the washing water, after being sprayed from the second nozzle 471 and falling along a parabolic curve, collides with the back surface of the blade 62, forming a wide contact area. As a result, the washing water adhering to the back surface of the blade 62 can be effectively rinsed away. That is, the washing water with relatively low discharge pressure and velocity collides with the back surface of the blade 62 as it falls, so most of the washing water that collides with the back surface of the blade 62 flows down along the back surface of the blade 62 and does not splash towards the second nozzle 471 side.

[0274] Figure 31 This is a schematic diagram of the flow of washing water discharged from the rotating nozzle.

[0275] Reference Figure 31 The pressure and velocity of the washing water discharged from the rotating nozzle 451, which is the first nozzle, are relatively greater than the pressure and velocity of the washing water discharged from the washing nozzle 471. Therefore, the mixing component 60 rotates in the direction of the rotational torque generated by the washing water discharged from the rotating nozzle 451.

[0276] In detail, the washing water flowing into the first discharge flow path 45 is sprayed from the rotating nozzle 451 at an angle corresponding to the tilt angle of the bottom of the first discharge flow path 45, thereby colliding with the front surface of the blade 62.

[0277] Even without fully closing the detergent dispenser 50, the leakage of washing water splashed after colliding with the front surface of the blade 62 to the outside of the detergent dispenser 50 can be minimized.

[0278] Furthermore, preferably, in order to allow the washing water discharged from the first nozzle 451 to be discharged downwards at an angle, the bottom of the first discharge flow path 45 is also formed at an angle similar to the bottom of the third discharge flow path 47, and the first nozzle 451 is located at a point higher than the upper end of the blade 62. This feature also applies to the third discharge flow path 47 and the second nozzle 471.

[0279] Furthermore, as described above, the washing water sprayed from the rotating nozzle 451 forms an angle of approximately 90 degrees with the front surface of the blade 62, thereby maximizing the rotational force of the mixing component 60.

[0280] As an example, the spray angle θ formed by the horizontal plane of the first nozzle 451 and the washing water discharged from the first nozzle 451, i.e., the angle formed by the horizontal plane of the first nozzle 451 and the extension line of the bottom surface of the first discharge flow path 45, can be set to 25 degrees. Under this condition, the tilt angle of the blade 62 can be set so that the washing water collides with the front surface of the blade 62 at an angle of approximately 90 degrees. That is, the angle formed by the front surface of the blade 62 and the extension line of the bottom surface of the first discharge flow path 45 can be set to 90 degrees.

[0281] However, it is not limited to this. In order to ensure that the angle formed by the washing water and the front surface of the blade 62 is about 90 degrees, the spray angle and the tilt angle of the blade 62 can be appropriately selected.

[0282] Furthermore, the point at which the washing water discharged from the rotary nozzle 451 collides with the front surface of the blade 62 is designed to be closer to the outer end of the blade 62 than the rotating shaft 61, thereby maximizing the rotational speed of the mixing component 60.
