Description

Technical Field

[0001] This invention relates to a washing machine. Background Technology

[0002] Typically, a washing machine is a device that allows users to put laundry into a washing tub and then performs the washing operation by properly mixing detergent and washing water.

[0003] Modern washing machines are equipped with detergent supply devices that can use both solid and liquid detergents. Detergent and washing water are supplied together into the washing tub along with the washing water.

[0004] The problem is that when powdered or solid detergent is added to the detergent supply device, the detergent does not dissolve completely when the temperature of the supplied washing water is low, and it is supplied to the washing tank in a clump state.

[0005] To improve this problem, a washing machine has been developed with the following structure: a fan-shaped mixing component for dissolving powdered or solid detergent is provided in the detergent supply device, and water is sprayed toward the mixing component to make the mixing component rotate.

[0006] However, a problem with this type of washing machine is that when water is sprayed from the nozzle to make the mixing component rotate, powdered detergent splashes and contaminates the detergent supply device, or splashes outside.

[0007] Furthermore, the problem is that during the rotation of the mixing components, centrifugal force causes powdered detergent to move to the outside, resulting in incomplete dissolution of the detergent, and powdered detergent flowing into the washing tank. This leads to a serious problem of reduced washing quality due to residual detergent.

[0008] Furthermore, the problem lies in the structural durability of the fan-shaped mixing component, which can lead to blade damage or deformation and breakage of the mixing component. A particularly significant issue is the high likelihood of breakage due to the frequent washing required by the detergent supply device's operating environment. Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] The purpose of embodiments of the present invention is to provide a washing machine that improves washing quality by effectively dissolving powdered detergent.

[0011] The purpose of embodiments of the present invention is to provide a washing machine that prevents powder detergent from splashing, thereby preventing contamination of the detergent supply device.

[0012] The purpose of embodiments of the present invention is to provide a washing machine that strengthens the mixing components to prevent breakage.

[0013] Methods for solving problems

[0014] The washing machine provided in the embodiments of the present invention includes: a cabinet; a tub rotatably disposed inside the cabinet; and a detergent supply device disposed in the cabinet to supply detergent to the tub. The detergent supply device includes: a housing fixedly mounted in the cabinet and connected to a water supply device; a detergent dispenser removably mounted in the housing and having a recessed receiving portion for accommodating the detergent; and a mixing component rotatably disposed in the receiving portion to mix the detergent with water. The mixing component includes: a rotating shaft serving as the rotation center of the mixing component; a plurality of blades extending radially from the rotating shaft; and auxiliary blades extending at the extended ends of the blades in a direction intersecting the blades.

[0015] The auxiliary blades can be formed on the plurality of blades respectively.

[0016] The auxiliary blades can extend in the opposite direction to the rotation direction of the mixing component.

[0017] The auxiliary blades can extend along the circumferential direction of the mixing component.

[0018] The auxiliary blade may extend along the end of the blade away from the axis of rotation and extend upward from the lower end of the blade.

[0019] The auxiliary blades can be formed perpendicular to the bottom surface of the receiving portion or form an acute angle.

[0020] The hybrid component may include a ring connecting the extended ends of the plurality of blades.

[0021] Alternatively, the ring may connect the lower ends of the plurality of blades, and the auxiliary blades may extend from the blades along the ring.

[0022] The auxiliary blade can connect the end of the blade away from the axis of rotation to the upper end of the ring.

[0023] The auxiliary blade can be formed to be lower than the upper end of the blade.

[0024] The auxiliary blades can extend from the ring at the same height.

[0025] The length of the extension of the auxiliary blade can be made smaller than the interval between adjacent blades.

[0026] A nozzle may be provided on the inner side of the housing, and the nozzle sprays water supplied from the water supply device toward the blades to make the mixing component rotate.

[0027] It is permissible that the blade is tilted in the direction of rotation of the blade, and the extension line of the nozzle outlet intersects one side of the blade.

[0028] It is permissible that one side of the blade and the upper end of the auxiliary blade form a first predetermined angle, wherein the first predetermined angle is an obtuse angle.

[0029] Possibly, the mixing component includes a ring connecting the extended ends of the plurality of blades, with the lower end of the auxiliary blade forming a second predetermined angle with the ring, the second predetermined angle being larger than the first predetermined angle.

[0030] Possibly, the receiving portion includes: an arc-shaped portion formed in a shape corresponding to the outer diameter of the mixing component, forming the front half of the receiving portion; and a side portion extending from both sides of the arc-shaped portion to the rear end of the detergent dispenser, forming the two side surfaces of the receiving portion, the rear surface of the receiving portion opening towards the rear of the detergent dispenser.

[0031] Alternatively, a drain groove may be formed at the bottom of the receiving portion, the drain groove extending to the rear end of the detergent box to discharge the detergent from the receiving portion, and a rotating boss provided on the inner side of the drain groove, the rotating boss protruding upward so as to support the rotating shaft in a rotatable manner.

[0032] Alternatively, the lower end of the rotating shaft may extend further downward than the lower end of the blade and be housed inside the drainage groove, with the blade positioned above the drainage groove.

[0033] When the mixing component rotates, the blades and the auxiliary blades can pass through the drainage groove.

[0034] Invention Effects

[0035] The washing machine provided in the proposed embodiments can achieve the following effects.

[0036] The washing machine provided in the embodiments of the present invention may have auxiliary blades provided at the ends of the blades of the mixing component that is rotatably disposed in the housing.

[0037] It has the following advantages: the auxiliary blades prevent the powdered detergent from deviating from and detaching from the mixing components as the blades move circumferentially, guiding it into the gap space between the blades, thereby facilitating the mixing and dissolution of the washing water and the powdered detergent. By effectively dissolving the powdered detergent, it also prevents powdered detergent residue from remaining in the washing tank, thus improving washing quality.

[0038] It has the following particular advantages: when the washing water is sprayed onto the blades through the nozzle in order to rotate the mixing component, it can protect the powder detergent from splashing onto the outside of the mixing component, thereby preventing contamination of the detergent box and detergent supply device and maintaining a clean state.

[0039] The auxiliary blades have a structure that extends in the opposite direction to the rotation direction of the mixing component and along the ring, thereby enabling a more robust structure and improving durability, preventing damage to the mixing component even with repeated use and disassembly.

[0040] Furthermore, the auxiliary blade has a structure that connects the end of the mixing component to the ring, thereby not only preventing powder detergent from splashing and detaching, but also ensuring structural stability and smooth operation of the mixing component.

[0041] Furthermore, it has the following advantages: the blades and auxiliary blades have a shape inclined in the direction of rotation, which allows the hybrid component to be formed by rotating a simple mold, thus making it easy to manufacture. Also, since multiple cores are not used when forming the hybrid component, parting lines can be prevented from forming on the surface of the blades, thereby improving the appearance of the hybrid component.

[0079] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments that disclose the idea of ​​the present invention. Other regressive inventions or other embodiments included within the scope of the present invention can be easily proposed by adding, changing, or deleting other constituent elements.

[0080] Before proceeding with the explanation, let's define the direction. Embodiments of the present invention can be described as follows: Figure 1 , Figure 2 Using the central part of the washing machine shown as a reference, the direction towards the bottom surface where the washing machine is located is defined as downward, the direction towards the surface where the open inlet is formed in the cabinet is defined as upward, the direction towards the surface where the back panel is located is defined as rearward, and the direction towards the surface opposite to the rearward is defined as frontward. Furthermore, when undefined directions are mentioned, they can be defined based on the accompanying drawings for explanation.

[0081] Furthermore, it should be stated beforehand that the embodiments of the present invention are illustrated using a top-loading washing machine with a door formed on the upper surface and clothes placed through the open upper surface as an example. However, the present invention is not limited to the structure and form of the washing machine and can be applied to washing machines of all forms equipped with a detergent supply device. For example, the present invention can be applied to various types of washing machines, including drum washing machines.

[0082] Figure 1 This is a perspective view of a washing machine provided in an embodiment of the present invention. Figure 2 This is a rear view of the washing machine.

[0083] Reference Figure 1 as well as Figure 2 The washing machine 1 provided in the embodiments of the present invention 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 mounted on the rear edge of the upper frame 12.

[0084] In detail, the cabinet 10 can form the appearance of the washing machine 1 and has a washing space inside.

[0085] As an example, the cabinet 10 can be formed in a hexahedral shape with an open upper surface, and the upper frame 12 covers the open upper surface of the cabinet 10. Furthermore, an entry port 101 is formed in the upper frame 12 (see reference). Figure 3 The door 13 opens and closes the input port 101.

[0086] Furthermore, a tub 11 communicating with the inlet 101 is housed inside the cabinet 10. The upper surface of the tub 11 may be open and communicating with the inlet 101, and a washing basin for holding clothes may be housed inside the tub 11. The washing basin may include a cylindrical drum. Moreover, a drive device such as a motor for driving the drum may be provided inside the cabinet 10.

[0087] As an example, the control panel 14 may be provided on the upper surface of the upper frame 12 at a position 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 a button. Moreover, the control panel 14 may also include a display for showing the operation of the washing machine 1.

[0088] Alternatively, the rear end of the door 13 can be rotatably connected to the upper frame 12, and the user can open or close the inlet 101 by raising or lowering the front end of the door 13. Furthermore, the door 13 can be configured to be at least partially transparent. Therefore, the user can view the interior of the washing tub through the transparent portion of the door 13.

[0089] On the other hand, the rear surface of the cabinet 10 can be formed by a rear cover 102. When the rear cover 102 is separated or removed, it becomes accessible for maintenance of components located inside the washing machine 1. For example, when the rear cover 102 is separated, the power supply device 16, water level sensor 17, water supply device 15, etc., located on the control panel 14 can be replaced or repaired.

[0090] Furthermore, a water supply pipe connection 152 can be provided on the rear surface of the cabinet 10. A water supply hose extending from an external water source can be connected to the water supply pipe connection 152. The water supply pipe connection 152 can be the water supply device 15 described later (see reference). Figure 4 The water supply device 15 may include multiple valves and is connected to a 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. Hereinafter, the water supply device 15 will be described in more detail with reference to the accompanying drawings.

[0091] 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 can be connected to the water supply device 15, and the detergent added to the detergent supply device 20 mixes with the water supplied from the water supply device 15 before being supplied to the interior of the tank 11.

[0092] The detergent supply device 20 will now be described in more detail with reference to the accompanying drawings.

[0093] Figure 3 This is a perspective view of the upper frame showing the detergent dispenser being pulled out. Figure 4 This is a perspective view of the detergent supply device.

[0094] Reference Figure 3 as well as Figure 4 The upper frame 12, which has the input port 101, is combined with the upper surface of the cabinet 10.

[0095] In detail, the upper frame 12 forms the upper part of the washing machine 1, and the inlet 101 can be closed by the door 13. Furthermore, the control panel 14 can be disposed on the rear side of the upper surface of the upper frame 12.

[0096] Furthermore, the detergent supply device 20 can be disposed on the upper frame 12. The detergent supply device 20 can be inserted into the frame opening 121, which is formed on one side of the inlet 101, specifically on the rear surface of the inlet 101. Moreover, the detergent supply device 20 is installed inside the upper frame 12 via the frame opening 121. The detergent supply device 20 includes: a housing 30 fixed inside the upper frame 12; a detergent cartridge 50 that is connected to the housing 30 in an infeedable manner; and a flow path component 40 that is connected to the housing 30 to form a flow path for water supplied to the detergent cartridge 50. Furthermore, in the closed state, i.e., when inserted inside the housing 30, the front surface of the detergent cartridge 50 can form part of the rear surface of the inlet 101.

[0097] The detergent supply device 20 can be disposed at the lower center of the control panel 14. Furthermore, on the left and right edges of the control panel 14, corresponding to the left and right edges of the detergent supply device 20, respectively, are provided a power supply device 16, which supplies power for driving the washing machine 1; and a water level sensor 17, which senses the water level in the tub 11. Moreover, a PCB can be disposed in the central portion of the control panel 14 above the detergent supply device 20, and the PCB is electrically connected to various components, including the operating section, disposed on the front surface of the control panel 14.

[0098] Furthermore, the water supply device 15 can be connected to the rear end of the detergent supply device 20. Moreover, when the detergent supply device 20 is installed, the water supply device 15 can be exposed to the outside from the rear surface of the washing machine 1 and connected to the water supply pipe.

[0099] The water supply device 15 can be connected to the housing 30 of the detergent supply device 20. The water supply device 15 may include multiple valves for supplying water to the detergent supply device. Moreover, the water supply device 15 includes a hot water pipe connection 152a for supplying hot water and a cold water pipe connection 152b for supplying cold water, both of which may be exposed on the rear surface of the cabinet 10.

[0100] The water supply device 15 is connected to the rear surface of the housing 30, and the flow path component 40 is installed on the inner upper surface of the housing 30 to form a flow path communicating with the water supply device 15. Furthermore, when the detergent dispenser 50 is closed, the flow path component 40 is positioned above the detergent dispenser 50. Therefore, water can fall from above the detergent dispenser 50 via the flow path component 40, and the falling water can mix with the detergent placed inside the detergent dispenser 50 before being supplied to the tub 11.

[0101] 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. Moreover, the flow path component 40 may have independent flow paths respectively leading to the first receiving portion 54, the second receiving portion 55, and the third receiving portion 56. That is, the advantage is that by installing only one flow path component 40 onto the housing 30, multiple flow paths can be provided to supply water to the multiple receiving portions 54, 55, and 56 formed in the detergent dispenser 50.

[0102] Hereinafter, the detailed structure of the housing 30, flow path component 40, and detergent box 50 constituting the water supply device 15 will be described in detail with reference to the accompanying drawings.

[0103] Figure 5 This is an exploded perspective view showing the detergent dispenser separating from the housing of the detergent supply device, viewed from the front. Figure 6 This is an exploded perspective view of the rear of the detergent dispenser, viewed with the dispenser separated from the housing. Figure 7 This is an exploded perspective view of the detergent supply device.

[0104] Reference Figures 5 to 7 The housing 30 can be molded into a box shape with an open front surface, and can have an internal receiving space 300 for accommodating the flow path component 40 and the detergent dispenser 50. As an example, the housing 30 can be molded as a single unit by plastic injection molding.

[0105] The water supply device 15 can be connected to the rear surface of the housing 30, and the water supplied via the water supply device 15 can be supplied to the detergent dispenser 50 through the flow path component 40. For this purpose, the flow path component 40 can be integrated with the interior of the housing 30.

[0106] In detail, the flow path component 40 can be installed on the inner upper surface of the housing 30. Furthermore, multiple flow paths with open upper surfaces can be formed in the flow path component 40. Therefore, when the flow path component 40 is installed in the housing 30, one or more flow paths can be formed to supply water to the detergent dispenser 50 through the housing 30 and the flow path component 40. Moreover, with the flow path component 40 installed, the one or more flow paths can communicate with the water supply device 15.

[0107] When installed in the housing 30, the flow path component 40 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 be allowed to fall onto the detergent dispenser 50 over the entire area of ​​the upper surface of the receiving space 300.

[0108] The detergent dispenser 50 can be accommodated in the receiving space 300. The detergent dispenser 50 can be configured to be pushed in and pulled out via the open front surface of the housing 30. The detergent dispenser 50 can be provided in the form of a drawer, forming a plurality of downwardly recessed receiving portions 53. Detergent for washing can be filled into the plurality of receiving portions 53.

[0109] As an example, the receiving portion 53 may include: a first receiving portion 54 for receiving powdered detergent; a second receiving portion 55 for receiving liquid detergent; and a third receiving portion 56 for receiving fabric softener. Of course, the second receiving portion 55 or the third receiving portion 56 may be omitted if necessary.

[0110] 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. Moreover, the water supplied from the water supply device 15 can be supplied separately and independently to the first receiving portion 54, the second receiving portion 55, and the third receiving portion 56.

[0111] 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 may be rotatably disposed in the first receiving portion 54. The mixing component 60 can be driven through a nozzle 451 (see reference 40) formed in the flow path component 40. Figure 15 The water being sprayed rotates. The mixing component 60 can be defined as a rotating component or a mixing fan.

[0112] When washing water is supplied via the nozzle 451 while the powdered detergent is placed in the first container 54, the mixing member 60 rotates and mixes the washing water and the powdered detergent. Furthermore, the powdered detergent can be supplied from the first container 54 to the tank 11 in a dissolved state. For this purpose, at least a portion of the rear surface of the first container 54 can be open.

[0113] Receiving cover 57 may be disposed on the second receiving portion 55 and the third receiving portion 56. The receiving cover 57 may be placed on the open upper surface of the second receiving portion 55 and the third receiving portion 56, and is formed inclined downward along the concave shape of the second receiving portion 55 and the third receiving portion 56. Moreover, cover holes 571, 572, 575, and 576 (see reference) may be formed at the bottom of the concave portion of the downwardly inclined receiving cover 57 and at the rear end of the receiving cover 57. Figure 13 Water falling from the flow path component 40 is supplied to the cover hole.

[0114] In this embodiment, the receiving cover 57 is shown as a single-piece recess corresponding to the second receiving portion 55 and the third receiving portion 56, but it may also be provided as an additional structure that respectively closes the second receiving portion 55 and the third receiving portion 56.

[0115] The housing 30 will now be described in more detail with reference to the accompanying drawings.

[0116] Figure 8 This is a three-dimensional view of the housing integrated with the flow path components, viewed from the lower front side. Figure 9 This is an exploded perspective view of the housing and flow path components from above. Figure 10This is an exploded perspective view of the housing and flow path components viewed from below.

[0117] Reference Figures 8 to 10 The housing 30 may be configured with an open front surface and a hexahedral shape forming an internal accommodating space 300. As an example, the housing 30 may include an upper housing surface 31, a lower housing surface 32, a pair of housing side surfaces 33, and a rear housing surface 34.

[0118] A housing mounting portion 311 may be formed on the upper surface 31 of the housing. The housing mounting portion 311 can be coupled to the upper frame 12. As an example, the housing mounting portion 311 may include a boss for fastening a screw and is formed in the frame fastening portion 122 of the upper frame 12 (see reference). Figure 3 The corresponding position. Moreover, the screw passing through the frame fastening part 122 is fastened to the housing mounting part 311, so that the housing 30 can be fixed to the upper frame 12.

[0119] Furthermore, the side mounting portion 331 can protrude from the outer surface of the side surface 33 of the housing. In detail, the side mounting portion 331 protrudes laterally from the side surface 33 of the housing, and a screw passing through the side mounting portion 331 is engaged with the upper frame 12, so that the housing 30 can be firmly fixed inside the upper frame 12.

[0120] A housing guide 332, which is stepped on the side 33 of the housing, is formed to guide the insertion and removal of the detergent dispenser 50. A detergent dispenser guide 513 (refer to) formed on the detergent dispenser 50 is placed on the upper surface of the housing guide 332. Figure 13 ).

[0121] A detergent dispenser restraint portion 333 may be formed at the rear end of the side surface 33 of the housing. An elastic member is installed in the detergent dispenser restraint portion 333, and when the detergent dispenser 50 is fully pushed into the housing 30, the elastic member can restrain the detergent dispenser 50 through a protrusion 514 (see reference 514). Figure 13 Pressure is applied to the upper surface of the detergent dispenser 50 to prevent it from being pulled out.

[0122] A housing outlet 321 may be formed on the lower surface 32 of the housing, the housing outlet 321 being used to allow wash water mixed with detergent in the detergent box 50 to fall downwards. Multiple housing outlets 321 may be arranged in the region adjacent to the front end 322 of the lower surface 32 of the housing. Furthermore, the front end 322 of the lower surface 32 of the housing may be formed into a rearwardly recessed shape.

[0123] The water supply device 15 can be installed on the rear surface 34 of the housing. Furthermore, a rearwardly protruding connection port 341 can be formed on the rear surface 34 of the housing. The connection port 341 can be connected to the water supply body 151. The connection port 341 may include a hot water port 342 and a cold water port 343. Moreover, the cold water port 343 may include a first cold water port 343a and a second cold water port 343b. The hot water port 342, the first cold water port 343a, and the second cold water port 343b communicate with the distribution flow path 43 formed in the flow path component 40 when the flow path component 40 is installed.

[0124] The flow path component 40 can be formed to a size corresponding to the upper surface 31 of the housing. As an example, the flow path component 40 can be formed to the following size: when the flow path component 40 is 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 sides of the flow path component 40 extend to the left and right sides of the upper surface 31 of the housing.

[0125] Furthermore, the rear end of the flow path component 40 can extend downward to contact the rear surface 34 of the housing. Also, the rear surface of the flow path component 40 can communicate with the connection port 341 connected to the water supply device 15.

[0126] The flow path component 40 may be formed with a distribution flow path 43 for supplying water to the receiving portion 53 and a discharge flow path 44. Furthermore, the discharge flow path 44 may be formed with a recessed depth, and separate flow paths may be formed by combining the discharge flow path 44 with the housing 30. Hereinafter, the structure and function of the flow path component 40, including the flow paths 43 and 44, will be described in more detail with reference to the accompanying drawings.

[0127] Figure 11 This is a top view of the flow path components. Figure 12 yes Figure 4 12-12 sectional perspective view.

[0128] Reference Figure 11 as well as Figure 12 The flow path component 40 may include an upper part 41, a rear part 42, and a corner portion R where the rear end of the upper part 41 meets the upper end of the rear part 42. The upper part 41 may be defined as a surface opposite to the upper surface 31 of the housing. Moreover, a portion of the upper part 41 contacts the upper surface 31 of the housing, while another portion is recessed to form a flow path for water supplied to the detergent dispenser 50. That is, the open upper surface of the flow path formed in the flow path component 40 can be closed by the upper surface 31 of the housing. The corner portion R may be configured as a rearwardly bulging arc shape.

[0129] The rear part 42 can extend downward from the rear end of the upper part 41. Furthermore, the rear part 42 can contact the rear surface of the housing 30. Moreover, the corner portion R is separated from the corner portion where the upper surface 31 and the rear surface 34 of the housing intersect, forming a defined space between the rear surface of the flow path member 40 and the rear corner of the housing 30. This defined space can be defined as a washing water supply space, which communicates with the connection port 341. Therefore, water supplied from the water supply device 15 to the housing 30 can flow through the washing water supply space and be supplied to the upper part 41. That is, the washing water discharged from the water supply device 15 and colliding with the corner portion R naturally flows towards the flow path formed in the upper part 41.

[0130] On the other hand, the 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.

[0131] As an example, the discharge path 44 may include: a first discharge path 45 that supplies water to the first receiving portion 54; and a second discharge path 46 and a third discharge path 47 that supply water to the mixing component 60. The function of the distribution path 43 is to separately supply water supplied from the water supply device 15 to the first to third discharge paths 45, 46, and 47.

[0132] Furthermore, the discharge path 44 may also include a fourth discharge path 48 for supplying water to the second receiving portion 55.

[0133] Furthermore, the discharge path 44 may also include a fifth discharge path 49 for supplying water to the third containment 56.

[0134] The distribution flow path 43 can extend laterally along the rear end of the flow path component 40. Furthermore, the distribution flow path 43 can disperse and supply water to the first discharge flow path 45, the second discharge flow path 46, and the third discharge flow path 47. Additionally, the distribution flow path 43 can also disperse and supply water to the fourth discharge flow path 48.

[0135] Specifically, the distribution flow path 43 can be formed at the corner portion R. Furthermore, the hot water port 342 and the cold water port 343 can be connected to the distribution flow path 43 to supply hot and cold water to the distribution flow path 43. The hot water port 342 and the cold water port 343 can be positioned relative to either the left or right edge of the distribution flow path 43. The hot water port 342 and the cold water port 343 can be positioned closer to the first discharge flow path 45 than the second discharge flow path 46.

[0136] Furthermore, multiple distribution ribs 430 may be formed in the distribution flow path 43. Water flowing along the distribution flow path 43 is divided and supplied to the multiple discharge flow paths 45-49 through the distribution ribs 430. Moreover, the distribution flow path 43 can be understood as a flow path formed between the distribution rib formed on the leftmost side and the distribution rib formed on the rightmost side.

[0137] The distribution rib 430 may include a guide rib 437 that guides water to the inside of the flow path component 40 in a unidirectional direction. The guide rib 437 may be formed in an arc shape or at an incline with a predetermined curvature so as to guide water supplied from the cold water port 343 to the left edge of the distribution flow path 43.

[0138] The distribution rib 430 may further include a first distribution rib 431 that guides the flow of hot and cold water. The first distribution rib 431 may be formed in an arc shape with a predetermined curvature at a location spaced apart from the guide rib 437 toward the left edge of the flow path component 40.

[0139] Specifically, the first distribution rib 431 extends forward in an arc shape from the rear end of the distribution flow path 43, i.e., the rear end of the flow path component 40. 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. Moreover, at least a portion of the supplied hot and cold water can be mixed at the end of the first distribution rib 431 and guided to the fourth discharge flow path 48. Furthermore, 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 portions spaced to the left from the fourth discharge flow path 48.

[0140] Furthermore, the auxiliary rib 436 can be located on the rear end side of the first distribution rib 431. Figure 11The auxiliary rib 436 extends horizontally to the side (right side of the first distribution rib 431). It extends towards the cold water port 343, specifically towards the first cold water port 343a. Furthermore, the auxiliary rib 436 extends downwards from the upper end of the first distribution rib 431. Moreover, the front end of the auxiliary rib 436 extends forward in a manner that contacts the corner portion R. By forming the auxiliary rib 436, excessive bypassing of cold water flowing from the rear of the flow path component 40 to the lower side can be prevented.

[0141] The distribution rib 430 may include a second distribution rib 432, which guides the flow of hot and cold water passing through the first distribution rib 431. The second distribution rib 432 may extend in a straight line for a predetermined length from a portion spaced apart from the end of the first distribution rib 431 toward the left end of the flow path component 40. Alternatively, the second distribution rib 432 may extend straight in the left-right direction, ensuring that the cold and hot water passing through the first distribution rib 431 flows in a straight line.

[0142] Alternatively, the distribution rib 430 may further include a third distribution rib 433, which guides water flowing toward 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.

[0143] The third distribution rib 433 can extend rearward. Moreover, the front half of the third distribution rib 433 can be formed in an arc shape, and the rear half can extend side by side with the second distribution rib 432.

[0144] Alternatively, the distribution rib 430 may also include a fourth distribution rib 434. The fourth distribution rib 434 may be a rib connecting the right end of the inlet of the first discharge flow path 45 to the rear end of the upper part 41, and may be formed by tilting forward from the right side closer to the left. Specifically, the left and right ends of the inlet of the first discharge flow path 45 may 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.

[0145] Alternatively, the distribution flow path 43 may further include a fifth distribution rib 435. Specifically, the fifth distribution rib 435 may extend forward from the rear end of the corner portion R and 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 extend in an arc or at an angle towards the left as it approaches the left side. 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.

[0146] Alternatively, the left end of the distribution flow path 43 may be defined by the left edge of the flow path component 40, and the right end may be defined by the blocking member 438. More specifically, the blocking member 438 may extend from the rear end of the flow path component 40 to the front end of the corner portion R, and may be formed at a location spaced to the left from the right end of the flow path component 40.

[0147] Furthermore, the blocking member 438 can be 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. Moreover, the second cold water port 343b communicates with the inlet of the fifth discharge flow path 49, thereby enabling the independent supply of cold water to the fifth discharge flow path 49.

[0148] On the other hand, the inlet (or rear end) of the discharge flow path 44 can communicate with the front end of the distribution flow path 43 and 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 stepped shape. Moreover, the remaining portion of the upper surface of the upper part 41, excluding the discharge flow path 44, contacts the bottom surface of the upper surface 31 of the housing. Therefore, the upper surface of the discharge flow path 44 is closed by the combination of the housing 30 and the flow path component 40, thereby completing the complete flow path.

[0149] The first to third discharge paths 45, 46, and 47 are provided in such a way that, when viewed from above the first receiving portion 54, they are disposed within the space defining the first receiving portion 54 and supply washing water to the first receiving portion 54.

[0150] In detail, 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 portion spaced to the right in the axial radial direction from the rotation center of the mixing component 60. Moreover, 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 be open toward the surface of the blade 62, and the opening shape of the nozzle 451 can be designed in various shapes.

[0151] On the other hand, the lower surface of the first discharge flow path 45 can extend downwards at a more downward angle as it approaches 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 impacts the surface of the blade 62 at a downward angle, thereby causing the mixing component 60 to rotate. As an example, the angle of inclination of the bottom surface of the first discharge flow path 45 can be set 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 a first nozzle 451.

[0152] Furthermore, the first discharge path 45 is located at a point radially separated from the rotation axis 61 of the mixing component 60, and the mixing component 60 is rotated by the torque generated by the washing water ejected from the nozzle 451. Therefore, the further away the point where the water ejected from the first nozzle 451 collides with the blade surface of the mixing component 60 is from the rotation axis 61 of the mixing component 60, the faster the rotational speed of the mixing component 60. Therefore, the extension position of the first nozzle 451 can be appropriately set according to the rotational speed of the mixing component 60, which optimizes the mixing of washing water and detergent.

[0153] The first discharge flow path 45 only needs to provide enough flow to make the mixing component 60 rotate at a set 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.

[0154] The second discharge flow path 46 extends forward from the distribution flow path 43 and passes through the center of the first receiving portion 54. Furthermore, the left edge of the second discharge flow path 46 extends forward from the end of the fifth distribution rib 435. The second discharge flow path 46 extends to the front end of the first receiving portion 54. The second discharge flow path 46 also extends to the front end of the flow path component 40. Here, the first receiving portion 54 can be defined as extending to the portion that is arc-shaped along the circumferential surface of the mixing component 60. 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 into the first receiving portion 54.

[0155] The second discharge path 46 can be configured such that water used to dissolve the powdered detergent filling the interior of the first container 54 and wash away the detergent adhering to the surface of the first container 54 falls from the upper side of the first container 54. For this purpose, a plurality of spray holes 463 can be formed in the second discharge path 46. The spray holes 463 are evenly arranged within the first container 54, thereby minimizing the presence of powdered detergent residue inside the first container 54. The spray holes 463 can be defined as first spray holes 463 to distinguish them from the second spray hole 481 and the third spray hole 491 described below.

[0156] Furthermore, the second discharge path 46 may include: a main portion 461 extending forward from the distribution path 43; and an extension portion 462 extending to both sides from the front end of the main portion 461. That is, it can be designed such that the main portion 461 corresponds to the main body of the arrow and the extension portion 462 corresponds to the head of the arrow.

[0157] Furthermore, multiple first spray holes 463 may be formed along the main portion 461 and the extension portion 462. The first spray holes 463 may be formed to penetrate the flow path member 40 in the vertical direction. Moreover, the first spray holes 463 are formed in a nozzle-shaped spray portion 466 protruding downwards from the lower surface of the flow path member 40. However, depending on the shape of the spray portion 466 or the configuration of the first spray holes 463, the first spray holes 463 may also penetrate the flow path member 40 at a downward angle, rather than penetrating vertically downwards.

[0158] The main portion 461 can extend from the distribution flow path 43 and further forward past the center of the mixing component 60. Furthermore, the extension portion 462 can extend from the front end of the main portion 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 portion 461. At least a portion of the edge of the extension portion 462 can be formed in an arc shape with a curvature corresponding to the curvature of the front surface edge of the first receiving portion 54. The first spray hole 463 can be formed in both the main portion 461 and the extension portion 462.

[0159] Furthermore, the first spray hole 463 may include: a main spray hole 464 formed in the main portion 461; and an extended spray hole 465 formed in the extended portion 462. Multiple main spray holes 464 may be configured and may be positioned to overlap with the mixing component 60 when viewed from above.

[0160] As an example, the main spray 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 spray hole 464 can fall to the end of the rotating shaft 61, flowing along its surface and washing away the powdered detergent adhering to it. Furthermore, the main spray 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 spray hole 464 can wash away the powdered detergent adhering to the surface of the blades 62.

[0161] Multiple extended spray holes 465 may be spaced apart along the front end of the extension portion 462. Furthermore, when viewed from above, the extended spray holes 465 may be located directly above the arc-shaped front surface of the first receiving portion 54. For example, as the front surface of the first receiving portion 54 is formed in an arc shape, the multiple extended spray holes 465 may also be arranged along an imaginary arc extending along the front surface of the first receiving portion 54. Moreover, one or more extended spray holes 465 may also be formed at a location corresponding to the edge of the blade 62 and the rotation axis 61. In this case, the extended spray holes 465 may be positioned corresponding to the ring 63 of the mixing component 60. Therefore, water falling from the main spray hole 464 can wash away the powdered detergent adhering to the blade 62, especially to the ring 63.

[0162] The third discharge path 47, used for washing powdered detergent adhering to the surface of the blade 62, can be configured to the side of the second discharge path 46. Furthermore, with the second discharge path 46 as a reference, the first discharge path 45 and the third discharge path 47 can be configured side-by-side on opposite sides. The surface of the blade 62 (rear surface) impacted by the washing water discharged from the third discharge path 47 can be understood as the opposite surface of the blade 62 (front surface) impacted by the washing water sprayed from the nozzle 451 of the first discharge path 45.

[0163] The third discharge path 47 can extend forward from the distribution path 43. The third discharge path 47 can be recessed into the upper part 41. Moreover, the third discharge path 47 can extend to a position where it overlaps with at least a portion of the mixing component 60 in the vertical direction when viewed from above. Similar to the first discharge path 45, the third discharge path 47 can be formed with its bottom surface sloping downwards towards the front.

[0164] A second nozzle 471 may be formed at the lower end of the front surface of the third discharge flow path 47, and the second nozzle 471 sprays 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. Moreover, the water sprayed from the second nozzle 471 is directed toward the rear surface of the blade 62.

[0165] On the other hand, the fourth discharge flow path 48 may be located above the second receiving portion 55. The fourth discharge flow path 48 may extend forward from the distribution flow path 43. The fourth discharge flow path 48 may be recessed downward from the upper part 41. Moreover, a plurality of second spray holes 481 may be formed in the fourth discharge flow path 48. The second spray holes 481 may be configured to penetrate the fourth discharge flow path 48 and be open, so that water supplied to the fourth discharge flow path 48 may fall downward. The second spray holes 481 may include a plurality of first front holes 482 and a plurality of first rear holes 483.

[0166] The fifth discharge flow path 49 may be located above the third receiving portion 56. The fifth discharge flow path 49 may extend forward from the distribution flow path 43. Possibly, the fifth discharge flow path 49 may communicate with an additional distribution flow path formed between the blocking member 438 and the right side end of the flow path component 40, and the width of the fifth discharge flow path 49 may be larger than the width of the additional distribution flow path. That is, the right side of the fifth discharge flow path 49 may be defined by the right side of the flow path component 40, and the left side of the fifth discharge flow path 49 may be formed at a location spaced to the left from the blocking member 438.

[0167] The additional distribution flow path is located in front of the second cold water port 343b, and the washing water flowing into the second cold water port 343b is supplied to the fifth discharge flow path 49. Moreover, the fifth discharge flow path 49 can extend further forward past the center of the third receiving portion 56.

[0168] The fifth discharge passage 49 can be recessed downward from the upper part 41. Furthermore, a plurality of third spray holes 491 can be formed in the fifth discharge passage 49. The third spray holes 491 can be configured to extend through the fifth discharge passage 49 and be open, allowing water supplied to the fifth discharge passage 49 to fall downward.

[0169] The third spray hole 491 may include a plurality of second front holes 492 and a plurality of second rear holes 493.

[0170] On the other hand, a plurality of discharge portions 421 can be recessed on the back side of the rear part 42. When the water pressure supplied from the water supply device 15 is high, a portion of the supplied water flows through the discharge portions 421 to the lower back side of the housing 30. Through the plurality of discharge portions 421, even if the pressure of the water supplied from the water supply device 15 increases instantaneously, it is possible to prevent water from flowing back to the water supply device 15 or the water supply pipe connection portion 152 and causing leakage.

[0171] Side guides 412 may be formed at both ends of the flow path component 40. Furthermore, a side limiting portion 413 may protrude downwards from the bottom surface of the side guide 412. The side limiting portion 413 protrudes downwards from the front end of the side guide 412, and when the detergent dispenser 50 is pulled out to its maximum extent, the side limiting portion 413 and the limiting protrusion 514 formed on the detergent dispenser 50 (see reference) Figure 13 Interference, thereby preventing the detergent cartridge 50 from separating.

[0172] On the other hand, a sidewall 411 may be formed at one of the two end portions of the flow path component 40 at a location corresponding to the bottom surface of the side guide 412. The sidewall 411 extends downward from the outermost edge of the bottom surface of the side guide 412 and extends rearward by a predetermined length, and when the flow path component 40 is mounted on the housing 30, the sidewall 411 contacts the side surface of the housing 30. Therefore, the detergent dispenser guide 513 is positioned between the lower end of the sidewall 411 and the upper surface of the housing guide 332.

[0173] The detergent dispenser 50 will now be described in more detail with reference to the accompanying drawings.

[0174] Figure 13 This is an exploded perspective view showing the detergent dispenser, mixing components, and container lid separated from the viewer. Figure 14 This is an exploded perspective view showing the detergent dispenser separated from the mixing component and the container lid, viewed from below. Figure 15 This is a partial perspective view showing the hybrid component installed in the receiving portion. Figure 16 This is an exploded perspective view showing the situation of separation from the mixing component from the receiving portion. Figure 17 yes Figure 15 17-17 sectional perspective view.

[0175] Reference Figures 13 to 17 The detergent dispenser 50 is provided in the form of a drawer with its upper surface open, and can be inserted into the receiving space of the housing 30 or pulled forward from the receiving space.

[0176] Specifically, the detergent dispenser 50 may include: a detergent dispenser body 51 having the 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 close the frame opening 121 when the detergent dispenser 50 is pushed in. Furthermore, the detergent dispenser 50 can be pulled out by inserting a finger into the back of the detergent dispenser handle 52 and pulling it forward. For this purpose, an upwardly recessed handle groove 520 may be formed between the front surface 52 of the detergent dispenser and the detergent dispenser body.

[0177] The receiving portion 53 may be recessed into the upper surface of the detergent dispenser body 51. The receiving portion 53 may include a first receiving portion 54 for mounting the mixing component 60. Furthermore, the receiving portion 53 may also include a second receiving portion 55 and a third receiving portion 56 arranged side by side to the first receiving portion 54.

[0178] A first receiving portion 54 may be recessed into the detergent dispenser body 51. Furthermore, a mixing component 60 may be provided in the first receiving portion 54. Powdered detergent and water may be contained in the first receiving portion 54, and the powdered detergent and water may be mixed by the rotation of the mixing component 60, thereby ensuring the smooth dissolution of the powdered detergent. Moreover, the dissolved powdered detergent and water may be discharged through the rear of the first receiving portion 54.

[0179] The detergent dispenser body 51 may also include a second receiving portion 55 and a third receiving portion 56. The second receiving portion 55 and the third receiving portion 56 may be arranged side by side to the side of the first receiving portion 54. The second receiving portion 55 and the third receiving portion 56 differ only in their positions, but their shapes may be the same.

[0180] The following description is based on the shape of the second receiving portion 55, and the detailed description of the third receiving portion 56 is omitted. Of course, the second receiving portion 55 or the third receiving portion 56 may also be omitted if necessary.

[0181] The second receiving portion 55 may have an open upper surface and be recessed downwards. Furthermore, the open upper surface of the second receiving portion 55 may be square in shape. The bottom of the second receiving portion 55 may be sloped downwards towards the rear end. 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 extending vertically through the siphon boss 551 is formed inside the siphon boss 551, allowing the detergent water dissolved in the second receiving portion 55 to drain below the detergent dispenser 50. A siphon recess 553 may be formed at the lower edge of the siphon boss 551.

[0182] Furthermore, the detergent dispenser 50 may also include a receiving cover 57 placed in the second receiving portion 55. The receiving cover 57 may be formed from a single unit that simultaneously covers the second receiving portion 55 and the third receiving portion 56, or it may be composed of two separate covers.

[0183] The edge of the receiving cover 57 can be placed on the stepped portion 511, which is stepped along the upper surface edge of the second receiving portion 55 and the third receiving portion 56. Furthermore, a siphon extension 573 can be formed extending downwards from the bottom surface of the receiving cover 57. The siphon extension 573 can be configured as a cylindrical shape with an opening 574 formed on its lower surface, and when the receiving cover 57 is installed in the second receiving portion 55, the siphon boss 551 is inserted into the siphon extension 573.

[0184] Furthermore, the lower end of the siphon extension 573 can be placed on the siphon recess 553. Therefore, when water and detergent are supplied to the second receiving portion 55, the detergent mixture can rise along the space between the outer peripheral surface of the siphon protrusion 551 and the inner peripheral surface of the siphon extension 573, and be discharged below the detergent box 50 via the hollow 552 through the siphon action.

[0185] On the other hand, a first front cover hole 571 and a first rear cover hole 572 may be formed in the receiving cover 57. Water falling from the second spray hole 481 is guided through the first front cover hole 571.

[0186] The first rear cover hole 572 may be formed behind the siphon extension 573. The first rear cover hole 572 is located directly below the second spray hole 481, and the washing water falling from the second spray hole 481 fills the interior of the second receiving portion 55 through the through hole.

[0187] On the other hand, a siphon recess 563 and a siphon boss 561 with a hollow center 562 can be formed in the third receiving portion 56. Furthermore, the receiving portion cover 57 can close the third receiving portion 56. A siphon extension 577 for inserting the siphon boss 561 can be formed in the receiving portion cover 57. Moreover, a second front cover hole 575 and a second rear cover hole 576 can be formed in the receiving portion cover 57. The second front cover hole 575 and the second rear cover hole 576 can be formed with the same structure and shape as the aforementioned first front cover hole 571 and first rear cover hole 572.

[0188] A locking portion 512 may be formed on the upper surface of the detergent dispenser body 51. Furthermore, the detergent dispenser guide 513 may extend considerably along the front-to-back direction on both the left and right sides of the detergent dispenser body 51. An upwardly protruding limiting protrusion 514 may be formed at the rear end of the detergent dispenser guide 513.

[0189] On the other hand, the mixing component 60 can be provided in the detergent dispenser 50. The mixing component 60 can be provided in the first receiving portion 54 so that the powdered detergent supplied to the first receiving portion 54 is mixed with water and then discharged.

[0190] In detail, the first receiving portion 54 may open upwards and rearwards, and may have an internal space for accommodating the mixing component 60. The first receiving portion 54 may be recessed downwards beyond the height of the mixing component 60.

[0191] Furthermore, the first receiving portion 54 may include an arc-shaped portion 544. The arc-shaped portion 544 may form a front half including the front end of the first receiving portion 54. The arc-shaped portion 544 may be formed into a curved surface with a curvature corresponding to the outer diameter of the mixing component 60.

[0192] The arc-shaped portion 544 may be adjacent to the periphery of the mixing component 60, particularly to the ring 63 and auxiliary blades 64 of the mixing component 60. Therefore, when the mixing component 60 is mounted on the first receiving portion 54, the inner surface of the first receiving portion 54 does not contact the mixing component 60, but most of the powder detergent contained inside the first receiving portion 54 can be mixed through the mixing component 60. The two ends of the arc-shaped portion 544 may extend to positions corresponding to the left and right ends of the outer diameter of the mixing component 60.

[0193] Furthermore, the first receiving portion 54 may also include side portions 545. Possibly, the side portions 545 form the left and right sides of the first receiving portion 54 and extend parallel to each other at opposite positions. The side portions 545 may extend from the end of the arcuate portion 544 to the rear end of the detergent dispenser 50. As an example, the side portions 545 may be spaced at intervals equal to the distance between them and the rear end of the arcuate portion 544, and extend perpendicularly to the rear surface of the detergent dispenser 50.

[0194] Furthermore, the open rear surface of the first receiving portion 54 can be defined between the two side portions 545. Therefore, dissolved powdered detergent and water inside the first receiving portion 54 can be smoothly discharged to the open rear surface of the first receiving portion 54.

[0195] Furthermore, the first receiving portion 54 may also include a receiving portion guide 546. The receiving portion guide 546 extends from the front of the arcuate portion 544 to the rear end of the detergent dispenser 50. The receiving portion guide 546 may be formed to receive the arcuate portion 544 and the side portion 545, and is recessed on the upper surface of the detergent dispenser body 51. In particular, the receiving portion guide 546 may be formed obliquely from the front of the arcuate portion 544 toward the arcuate portion 544, so that washing water deviating from the arcuate portion 544 flows back toward the arcuate portion 544.

[0196] Furthermore, a rear plate 542 may be formed on the open rear surface of the first receiving portion 54. The rear plate 542 may extend such that it connects to the rear end of the side portion 545 at a portion spaced upward from the bottom of the first receiving portion 54.

[0197] The rear plate 542 prevents the powder detergent inside the first receiving portion 54 from being discharged all at once. Furthermore, the rear plate 542 prevents the mixing component 60 from detaching from the outside of the first receiving portion 54. The rear plate 542 can be formed at a location closer to the bottom than the upper surface of the first receiving portion 54.

[0198] A drainage groove 543 may be formed in the center of the bottom surface of the first receiving portion 54. Furthermore, the remaining bottom surface of the first receiving portion 54, excluding the drainage groove 543, may be formed as a plane of the same height.

[0199] The drain channel 543 can extend from a position corresponding to the central portion of the mixing component 60 to the rear end of the first receiving portion 54. The drain channel 543 can be recessed to a predetermined depth. Therefore, powdered detergent and water inside the first receiving portion 54 can be discharged along the drain channel 543.

[0200] Furthermore, a rotating boss 541 can be formed protruding from the inner side of the drainage groove 543, and the mixing component 60 is rotatably mounted on the rotating boss 541. The rotating boss 541 can support the rotating shaft 61 in a rotatable state inside the rotating shaft 61. As an example, a support portion 611 can be formed protruding downward inside the rotating shaft 61, and the support portion 611 can be placed on the shaft mounting portion 5411 recessed at the upper end of the rotating boss 541. Therefore, the mixing component 60 can rotate within the first receiving portion 54 about the rotating boss 541 as the central axis.

[0201] The mixing component 60 may be provided in a fan shape and, while rotating inside the first receiving portion 54, mixes the powdered detergent and washing water placed inside 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 referred to as a mixing fan, propeller, or screw. Furthermore, the mixing component 60 may also include auxiliary blades 64. Furthermore, the mixing component 60 may also include a ring 63.

[0202] The hybrid component 60 will now be described in more detail with reference to the accompanying drawings.

[0203] Figure 18 This is a perspective view of the hybrid component. Furthermore, Figure 19 This is a top view of the hybrid component. Furthermore, Figure 20 This is a rear view of the hybrid component. Furthermore, Figure 21 yes Figure 20 An enlarged view of part A. Furthermore, Figure 22 yes Figure 20 A magnified 3D view of part A. Furthermore, Figure 23 yes Figure 19 Sectional perspective view 23-23. Furthermore, Figure 24 yes Figure 18 Sectional perspective view 24-24. Furthermore, Figure 25 This is a side view of the hybrid component facing downwards. Furthermore, Figure 26 This is a side view of the hybrid component facing upwards. Furthermore, Figure 27 yes Figure 26 Enlarged view of part B.

[0204] The rotating shaft 61 can be formed at the center of the mixing component 60, becoming the rotation center of the mixing component 60. Moreover, the lower surface of the rotating shaft 61 can be open to form a space 610 for the rotating boss 541 to be inserted into the interior of the rotating shaft 61.

[0205] A downwardly extending support portion 611 can be formed in the inner space 610 of the rotating shaft 61. The support portion 611 can be formed into a shape that becomes narrower towards the bottom and makes point contact with the shaft mounting portion 5411. Therefore, the mixing component 60 can be in a state where it can rotate by water sprayed from the first nozzle 451.

[0206] A rotational shaft groove 613 may be formed on the inner surface of the rotational shaft 61. Multiple rotational shaft grooves 613 may be formed along the periphery of the rotational shaft 61. The rotational shaft groove 613 can improve the flow of resin injected during injection molding to form the hybrid component 60, thereby causing the air trap portion formed by the injected resin to move toward the mold dividing line.

[0207] In detail, the rotating shaft groove 613 can extend upward from the open lower surface of the rotating shaft 61. In this case, the rotating shaft groove 613 can extend upward from the protrusion 612. Furthermore, the rotating shaft groove 613 can extend along the extending direction of the rotating shaft 61, and can extend to the upper end of the inner side surface of the rotating shaft 61 or to the position of the support portion 611.

[0208] It is possible that the rotating shaft 61 is formed such that its inner diameter becomes narrower as it extends upwards, and the upper end of the rotating shaft 61 is formed into a sharp shape. Therefore, the rotating shaft groove 613 formed on the inner surface of the rotating shaft 61 can be formed such that its width becomes narrower as it extends upwards.

[0209] Furthermore, multiple rotating shaft grooves 613 can be arranged radially with reference to the center of the rotating shaft 61. In this case, the multiple rotating shaft grooves 613 can be arranged at equal intervals. The rotating shaft grooves 613 can also be arranged symmetrically with reference to the center of the rotating shaft 61. As an example, multiple rotating shaft grooves 613 can be arranged correspondingly on both sides with reference to the support portion 611. That is, two rotating shaft grooves 613 can be arranged on each side opposite to each other with reference to the center of the support portion 611. Moreover, the rotating shaft grooves 613 can also be arranged spaced apart on both sides with reference to one side of the extension of the support portion.

[0210] On the other hand, since the rotating shaft groove 613 is formed, the thickness of the periphery of the rotating shaft 61 can be formed differently depending on the range. Specifically, the thickness D2 of the periphery of the rotating shaft 61 with the rotating shaft groove 613 can be formed to be smaller than the thickness D1 of the periphery of the rotating shaft 61 without the rotating shaft groove 613. For example, the thickness D1 of the periphery of the rotating shaft 61 without the rotating shaft groove 613 can be formed to be 2.5 mm. Furthermore, the thickness D2 of the periphery of the rotating shaft 61 with the rotating shaft groove 613 can be formed to be 1.7 mm. That is, the wall thickness of the periphery of the rotating shaft 61 can be varied, and there can be a thickness difference of 0.8 mm at the location of the rotating shaft groove 613.

[0211] On the other hand, a rotating shaft groove 613 is formed inside the rotating shaft 61, and a shaft support portion 611 extends from the upper end of the inner surface of the rotating shaft 61.

[0212] The shaft support portion 611 includes: a support protrusion 6112 that extends downward from the upper end of the rotating shaft 61 by a predetermined length; and a support base 6111 that extends in a rib-like shape from the outer peripheral surface of the support protrusion 6112.

[0213] In detail, the lower end of the support base 6111 is sharply formed and rests on the upper surface of the rotating boss 541. Moreover, the support base 6111 includes a plurality of support ribs arranged at predetermined angles in the circumferential direction. For example, three support ribs may be arranged at 120-degree intervals.

[0214] A plurality of air gaps 612 may be recessed to a predetermined depth on the inner circumferential surface of the rotating shaft 61, and the plurality of air gaps 612 may be arranged at predetermined intervals in the circumferential direction. Moreover, the air gaps 612 extend from the lower end to the upper end of the rotating shaft 61, and their function is to allow air flowing into the rotating shaft groove 613 to be smoothly discharged to the outside of the rotating shaft 61 along the air gaps 612.

[0215] On the other hand, the rotating shaft 61 can extend further downward than the blade 62. Furthermore, the protrusion 612 at the lower end of the rotating shaft 61 can be inserted into the drainage groove 543. The length D of the rotating shaft 61 protruding downward relative to the blade 62 can correspond to the depth of the recess in the drainage groove 543.

[0216] Furthermore, the protrusion 612 can protrude laterally from the periphery of the rotating shaft 61. Moreover, the injection gate 69 can be connected to the protrusion 612, and the injection gate 69 is connected to the nozzle 733 during injection molding of the mixing component 60. That is, when injection molding the mixing component 60, resin can be injected from the lower end of the rotating shaft 61 to form the mixing component 60. Therefore, when removing the injection gate 69 after molding of the mixing component 60 is completed, the exposure of the connection portion of the injection gate 69 can be minimized.

[0217] Therefore, when molding the mixed component 60, the resin injected first fills the rotating shaft 61 through the injection gate 69. At this time, the flowability of the resin can be improved by the multiple rotating shaft grooves 613, thereby ensuring that the resin flows smoothly towards the blade 62 side.

[0218] Furthermore, since the height H2 of the upper end of the auxiliary blade 64 is formed to be the same as the height H1 of the blade 62 connected to the upper end of the rotating shaft, the cores 731 and 74 (see reference) of the mold device 70 that move up and down can be made to move. Figure 28 Separating lines L (refer to) Figure 28 The blade 62 is located at the upper end of the rotating shaft.

[0219] Therefore, a ventilation structure suitable for venting at the dividing line L is applicable, and the air trap can be removed by positioning the air trap at the dividing line L and utilizing the venting.

[0220] On the other hand, the rotating shaft 61 can extend further downward than the blade 62. Furthermore, the lower end of the blade 52 can be inserted into the drainage groove 543. The length D of the rotating shaft protruding downward relative to the blade 62 can correspond to the depth of the recess in the drainage groove 543.

[0221] Therefore, with the mixing component 60 installed, the lower end of the blade 62 can be located on the bottom surface of the first receiving portion 54. Furthermore, when the mixing component 60 rotates, the blade 62 can move while mixing the powdered detergent inside the first receiving portion 54.

[0222] Multiple blades 62 may be arranged radially along the periphery of the rotation axis 61. The blades 62 may be formed at an angle relative to the bottom of the first receiving portion 54. The blades 62 may also be formed at an angle less than 90 degrees relative to the bottom surface of the receiving portion 53.

[0223] The blade 62 is inclined at its upper end, which is located at a position deflected from the vertical plane toward the rotational direction of the blade 62, with the vertical plane passing through the lower end of the blade 62. That is, the blade 62 can be formed such that the closer it is from the lower end to the upper end, the more inclined it is toward the rotational direction of the mixing component 60. Therefore, when the mixing component 60 rotates, the powdered detergent at the bottom of the first receiving portion 54 can be effectively mixed.

[0224] Furthermore, the blade 62 can be formed at an angle orthogonal to the extension line of the outlet of the first nozzle 451. Therefore, water jetted from the first nozzle 451 can be made to strike the front surface of the blade 62 perpendicularly, causing the blade 62 to rotate. Alternatively, the blade 62 can be formed at an angle that is not orthogonal to the extension line of the outlet of the first nozzle 451 but intersects it.

[0225] Furthermore, the blade 62 can be configured such that the end in contact with the rotation axis 61 and the end 625 away from the rotation axis 61 have different inclination angles. Specifically, the end of the blade 62 in contact with the rotation axis 61 can be tilted at a first angle α1 with reference to a vertical line passing through the center of the rotation axis 61. Furthermore, the end 625 of the blade 62 away from the rotation axis 61 can be tilted at a second angle α2 with reference to the vertical line. As an example, the second angle α2 can be 55° to 60°. Moreover, the first angle α1 can be configured to be a smaller angle than the second angle α2.

[0226] Therefore, the blade 62 can be formed in a shape that is inclined overall in the direction of rotation, and at an angle that increases with distance from the axis of rotation 61. This structure prevents detergent from splashing from the tip of the blade 62 and allows it to mix with water supplied while in contact with the blade 62. Furthermore, the shape of the blade 62 with its continuous inclined structure allows the mold used to form the mixing component 60 to easily separate while rotating. Therefore, even without using multiple mold cores, a three-dimensional mixing component 60 can be formed, and injection molding can be performed without creating parting lines on the blade 62.

[0227] On the other hand, the lower end 624 of the blade can extend linearly from the rotation axis 61 to the end of the blade 62. In this case, the lower end of the blade 62 can be inclined lower as it gets closer to the rotation axis 61. By inclination of the lower end of the blade, the sliding core 731, which moves radially around the rotation axis 61, can be moved. The third angle α3 formed by the extension line of the lower end of the rotation axis 61 and the lower end 624 of the blade can be approximately 3° to 10°.

[0228] Furthermore, a blade recess 626 can be formed at the upper end 623 of the blade. The blade recess 626 can be recessed downward from the upper end 623 of the blade. The recess can extend from the rotation axis 61 to one side of the upper end 623 of the blade. The blade recess 626 allows for a larger vertical width on the side of the blade 62 away from the rotation axis 61. Moreover, to rotate the mixing component 60, water sprayed from the first nozzle 451 can impact the side of the blade 62 with a larger vertical width. Furthermore, the mixing of the powder detergent can be completed on the side of the blade 62 with a larger vertical width. Therefore, both the lightweight of the mixing component 60 and sufficient surface area for mixing the powder detergent can be achieved.

[0229] Furthermore, the mixing component 60 may include a ring 63. The ring 63 may be formed in a circular shape and form the edge of the mixing component 60. The ring 63 can connect a plurality of the blades 62 to maintain the overall shape of the mixing component 60. Moreover, the ring 63 can connect the lower ends 624 of a plurality of blades.

[0230] The function of the ring 63 is to minimize swaying while maintaining stable rotation when the mixing component 60 rotates. It also ensures overall strength for stably supporting the auxiliary blades 64 and maintaining their shape. Furthermore, it guides the powdered detergent mixed between the blades 62 to converge into the interior of the ring 63.

[0231] The ring 63 passes over the lower edge of the blade 62 in the radial direction, preventing the lower edge of the blade 62 from being exposed in a sharp and pointed state. As a result, even if a user touches the blade 62, they can avoid being scratched by the blade 62.

[0232] Possibly, the ring 63 extends upwards from the lower end of the blade 62 by a predetermined height, and the outer peripheral surfaces of the auxiliary blade 64 and the ring 63 form a smooth, single surface without steps. That is, the rotational trajectories of the auxiliary blade 64 and the ring 63 can be configured as a cylindrical shape having the height of the auxiliary blade 64 and a diameter corresponding to the diameter of the ring 63. Furthermore, when the mixing component 60 is mounted on the rotating boss 541, the bottom surface of the ring 63 can be separated from the bottom of the first receiving portion 54.

[0233] Furthermore, auxiliary blades 64 may be formed at the end of the blade 62. The auxiliary blades 64 may extend from the end of the blade 62 along the ring 63. Therefore, water and powdered detergent flowing along the blade 62 can be guided to mix inside the mixing component 60 without splashing outside the mixing component 60.

[0234] In detail, the auxiliary blades 64 can be formed on a plurality of blades 62. Furthermore, the auxiliary blades 64 can extend in a direction opposite to the rotation direction of the mixing component 60. That is, the auxiliary blades 64 can protrude from one of the two faces 621 of the blade 62 opposite to the first nozzle 451 in a direction opposite to the rotation direction of the mixing component 60. Therefore, in the event of splashing of powdered detergent due to water sprayed from the first nozzle 451, the auxiliary blades 64 can effectively block such splashing laterally.

[0235] The auxiliary blade 64 can extend along the end 625 of the blade 62 away from the rotation axis 61 and extend upward from the lower end of the blade 62. The auxiliary blade 64 can extend from the blade 62 along the ring 63. That is, the auxiliary blade 64 can extend with the curvature of the ring 63. Moreover, the auxiliary blade 64 can protrude from the end 625 of the blade 62 away from the rotation axis 61. The auxiliary blade 64 can connect one end of the blade 62 to the upper end of the ring 63. Therefore, when powder detergent splashes in the gap space between the blades 62, it can be protected laterally by the auxiliary blade 64.

[0236] The extension length of the auxiliary blade 64 can be made smaller than the interval between the auxiliary blade 64 and the adjacent blade 62. Specifically, the length L1 of the auxiliary blade 64 extending from one side 621 of the blade 62 can be made smaller than the distance L2 from the end of the auxiliary blade 64 to the other side 162 of the adjacent blade 62. For example, the ratio of the length L1 of the auxiliary blade 64 to the distance L2 from the auxiliary blade 64 to the other side 162 of the adjacent blade 62 can be 1:2.

[0237] Furthermore, the height h1 of the auxiliary blade 64 extending upward from the ring 63 can be lower than the height h2 from the ring 63 to the upper end 623 of the blade. As an example, the ratio of the height h1 of the auxiliary blade 64 to the height h2 from the ring 63 to the upper end 623 of the blade can be 1:2.

[0238] The auxiliary blade 64 can be formed by extending from the ring at the same height. Moreover, the auxiliary blade 64 can be formed to be lower than the upper end of the blade 62.

[0239] On the other hand, with the lower end 264 of the blade as a reference, the height H2 of the auxiliary blade 64 can be formed to be the same as the height H1 of the upper end of the blade 62 connected to the rotating shaft 61.

[0240] Therefore, in the mold device 70 that separates the upper and lower parts (refer to...) Figure 28 Cores 731 and 74 (refer to) Figure 28 The dividing line L (refer to) Figure 28 When the position of the blade 62 corresponds to the height H2 of the auxiliary blade and the height H1 of the upper end of the blade 62 connected to the rotating shaft 61, exhaust can be performed at that position to remove the air trap.

[0241] That is, the flow of the injected resin during injection molding of the mixed component 60 can be improved by forming a rotation shaft groove 613 on the rotation shaft 61, and the position of the air trap where the resin converges can be guided to the dividing line side to remove the air trap.

[0242] The size of the auxiliary blade 64 should be sufficient to block the powder detergent from flowing or splashing outwards along the blade 62. If the length of the auxiliary blade 64 is too large, the flow of water inside the first receiving portion 54 may be poor, and the rotational performance of the mixing component 60 may be reduced due to its increased weight.

[0243] Furthermore, the auxiliary blade 64 can also be formed perpendicular to the bottom surface of the first receiving portion 54 or at an acute angle slightly inclined towards the rotation axis 61. That is, the auxiliary blade 64 can also be inclined such that the further it extends from the lower end upwards, the more it is inclined towards the rotation axis 61. Therefore, powdered detergent flowing along the blade 62 or colliding with the auxiliary blade 64 can be guided back to the inner region of the ring 63.

[0244] On the other hand, the auxiliary blade 64 can be configured such that its end is inclined toward the rotational direction of the blade 62, i.e., the direction in which the blade 62 is inclined. Specifically, one surface 621 of the blade 62 and the upper end of the auxiliary blade 64 can be formed at a first predetermined angle β1. In this case, the first predetermined angle β1 can be an obtuse angle. Furthermore, the lower end of the auxiliary blade 64 and the ring 63 can be formed at a second predetermined angle β2. In this case, the second predetermined angle β2 can be larger than the first predetermined angle β1.

[0245] Therefore, by means of the inclined shape of the blade 62 and the auxiliary blade 64, during the injection molding of the hybrid component 60, the rotating core 74 (see reference) can be made to rotate. Figure 28 While rotating, it separates from the mixing component 60. Moreover, the mixing component 60 can have a structure that can form the blade 62 and the auxiliary blade 64 without using multiple cores.

[0246] The auxiliary blade 64 can extend upwards and to the side a predetermined height from the upper surface of the ring 63. As an example, the auxiliary blade 64 can extend to a position equivalent to half the length between the upper and lower ends of the blade 62.

[0247] The auxiliary blade 64 includes an upper surface 641 and a side surface 642. The side surface 642 refers to the circumferential end of the auxiliary blade 64, and can be inclined in the same direction as the radial end of the blade 62. Furthermore, the corner where the upper and lower surfaces of the auxiliary blade 64 meet can be gently curved with a predetermined curvature. At least one of the corners where the side surface of the auxiliary blade 64 meets the upper surface of the ring 63 and the corners where the upper surface of the auxiliary blade 64 meets the blade 62 is formed in an arc shape.

[0248] Hereinafter, the fan mold device 70 for a washing machine detergent supply device provided by an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[0249] Figure 28 This is a schematic diagram showing the mold assembly used to form the hybrid component. Furthermore, Figure 29 This is a diagram showing the configuration of the nozzle and gate for injection molding the mixed component.

[0250] As shown in the figure, the mold device 70 provided in the embodiment of the present invention may include: a fixed side 71, which remains fixed; and a movable side 72, which moves in the vertical direction with respect to the fixed side 71. Figure 28 It moves upwards in the left and right directions.

[0251] The fixed side 71 may include: a first fixed body 711, which remains fixed and is equipped with a sliding core 731, a vertically moving core 732, and an injection nozzle 733; and a second fixed body 712, which is disposed within the first fixed body 711 and moves the vertically moving core 732. An actuator 735 for actuating the vertically moving core 732 may also be provided on the fixed side 71.

[0252] Furthermore, the movable side 72 may include: a first movable body 721 that selectively contacts the first fixed body 711 and houses the rotating core 74; and a second movable body 722 that is fixedly mounted with the rotating core 74.

[0253] When the mold device 70 is closed, the hybrid component 60 can be molded. At this time, the first fixed body 711 and the first moving body 721 can be in contact with each other, and can separate when the moving side 72 moves. Therefore, the boundary where the first fixed body 711 and the first moving body 721 intersect can be defined as the dividing line. Furthermore, the sliding core 731 can be in a state of moving towards the rotation axis 61. Moreover, the vertically moving core 732 can be in a state of being inserted into the rotation axis 61. Since the vertically moving core 732 is in a downward moving state, the second fixed body 712 can also be in a downward moving state. Furthermore, the rotating core 74 can be in a state of contact with the blade 62 and the auxiliary blade 64 in a state of moving downward to the maximum extent.

[0254] When resin is injected from the injection nozzle 733 in this state, the resin can be injected through the injection gate 69 and the hybrid component 60 can be formed by the sliding core 731, the vertically moving core 732 and the rotating core 74.

[0255] On the other hand, the blade forming part 741 provided on the rotating core 74 can extend from the upper end of the rotating shaft 61 to the ends of the blade 62 and the auxiliary blade 64.

[0256] After the resin is injected and the hybrid component 60 is formed, the movable side 72 can move upward. At this time, the first movable body 721 can remain in contact with the first fixed body 711, and only the second movable body 722, to which the rotating core 74 is fixed, moves upward.

[0257] The rotating core 74 moves together with the second moving body 722 as it moves upward. Furthermore, it can rotate as the second moving body 722 moves upward. The rotation direction of the rotating core 74 can be the same as the tilt direction of the blade 62 and the auxiliary blade 64.

[0258] Therefore, during the upward separation of the moving side 72, the rotating core 74 can be rotated in the same direction as the rotation direction of the blade 62 and the auxiliary blade 64, thereby forming the blade 62 and the auxiliary blade 64 in one step.

[0259] It is possible that after the rotating core 74 rotates and moves, the moving side 72 moves further upward, and the first moving body 721 separates from the first fixed body 711.

[0260] Furthermore, the sliding core 731 disposed on the fixed side 71 can move away from the rotation axis 61. Multiple sliding cores 731 can be arranged at equal angles around the rotation axis 61 and can selectively contact each other. For example, three sliding cores 731 can be arranged at 120° angles each.

[0261] By moving the sliding core 731, the sliding core 731 can change from a contact state to a separated state. Furthermore, when the sliding core 731 moves, its inclined portion 7311 moves along the lower end 624 of the blade, thereby separating from the mixing component 60. When the sliding core 731 stops moving, the mixing component 60 can be separated from the sliding core 731.

[0262] Furthermore, the vertically moving core 732 can be inserted into the inside of the rotating shaft 61, thus enabling it to form the internal shape of the rotating shaft 61 and support the hybrid component 60 separated from the sliding core 731.

[0263] On the other hand, the injection nozzle 733 can be disposed below the sliding core 731. The injection nozzle 733 can be disposed between adjacent sliding cores 731. Moreover, the injection gate 69, which is connected to the protrusion 612 of the rotation shaft 61 at the upper end of the injection nozzle 733, is also located at the boundary with the adjacent sliding core 731, thereby minimizing interference with the sliding core 731. Furthermore, when the sliding cores 731 move and separate from each other, the injection gate 69 can be located between the sliding cores 731.

[0264] As shown in the figure, when the molding of the mixing component 60 is completed, the vertically moving core 732 can move upward by moving the second fixed body 712. By moving the vertically moving core 732 upward, the mixing component 60 can move upward and completely separate from the sliding core 731. At this time, the injection gate 69 can move upward without interfering with the sliding core 731 while remaining attached to the mixing component 60.

[0265] Furthermore, by actuating the actuator 735, the rotating shaft core 736 inside the vertically moving core 732 moves rearward, completely separating the interior of the rotating shaft 61 from the rotating shaft core 736. Therefore, the mixing component 60 can be positioned such that the lower end of the rotating shaft 61 rests on the end of the vertically moving core 732, allowing the operator to separate the mixing component 60 from the vertically moving core 732. The injection gate 69 can be removed after separating the mixing component 60 from the vertically moving core 732.

[0266] This process can complete the molding of the hybrid component 60.

[0267] Hereinafter, the water flow state of the detergent supply device 20 having the structure described above will be described in detail with reference to the accompanying drawings.

[0268] Figure 30 This is a diagram showing the flow path of the washing water supplied to the detergent supply device. Figure 31 This is a diagram showing the configuration of the water inlets connected to the respective compartments of the detergent dispenser.

[0269] Reference Figure 30 as well as Figure 31 Water is supplied to the interior of the housing 30 upon the operation of the water supply device 15. Specifically, water can be supplied to the hot water port 342 and the cold water port 343 based on the selective operation of valves 153 and 154. At this time, the cold water supplied to the second cold water port 343b can be directly supplied to the fifth discharge flow path 49 via the additional distribution flow path, thereby supplying the third receiving section.

[0270] Water supplied to the hot water port 342 and the first cold water port 343a flows into the distribution flow path 43. The hot water flowing in through the hot water port 342 and the cold water flowing in through the first cold water port 343a can mix in the distribution flow path 43 and be guided to the discharge flow path 44 while flowing along the distribution flow path 43.

[0271] Washing water supplied via the first cold water port 343a and the hot water port 342 can flow along the distribution flow path 43 and be guided to the multiple discharge flow paths 45, 46, 47, 48 by the distribution of multiple guide ribs 430.

[0272] Washing water flowing into the first discharge flow path 45 after passing through the distribution flow path 43 can be supplied to the first receiving portion 54 via the first discharge flow path 45. The washing water flowing along the first discharge flow path 45 can be sprayed from the first nozzle 451 and collide with one side 621 of the blade 62, thereby causing the mixing component 60 to rotate.

[0273] Furthermore, a portion of the washing water flowing into the second discharge flow path 46 after passing through the distribution flow path 43 is supplied to the first receiving portion 54 via the second discharge flow path 46. The washing water supplied via the second discharge flow path 46 can be supplied to the inner surface of the first receiving portion 54 through the first spray hole 463. It can also be supplied to the mixing component 60 via the first spray hole 463.

[0274] Furthermore, a portion of the washing water flowing into the third discharge flow path 47 after passing through the distribution flow path 43 can flow into the third discharge flow path 47 and be supplied to the first receiving portion 54 via the third discharge flow path 47. Moreover, the washing water flowing along the third discharge flow path 47 can be sprayed from the second nozzle 471 to wash the rear surface of the blade 62.

[0275] Furthermore, a portion of the washing water that flows into the fourth discharge flow path 48 through the distribution flow path 43 can flow into the fourth discharge flow path 48, be discharged through the second spray holes 482 and 483 of the fourth discharge flow path 48, and be supplied to the second receiving portion 55 through the first cover holes 571 and 572 of the cover 57.

[0276] Furthermore, a portion of the washing water that flows into the fifth discharge flow path 49 after passing through the distribution flow path 43 can flow into the fifth discharge flow path 49, be discharged through the third spray holes 492 and 493 of the fifth discharge flow path 49, and be supplied to the third receiving portion 56 through the first cover holes 571 and 572 of the cover 57.

[0277] The operation of the washing water supplied from the flow path component 40 to each receiving section will now be described in more detail with reference to the accompanying drawings.

[0278] Figure 32 This diagram illustrates the spraying of washing water into the mixing component via a nozzle in the flow path component. Furthermore, Figure 33 This diagram illustrates the washing water falling into the first receiving portion through the first spray hole of the flow path component. Furthermore, Figure 34 This is a perspective view showing the flow of detergent inside the container. Furthermore, Figure 35 yes Figure 34Enlarged view of part B.

[0279] Reference Figures 32 to 35 Water flowing along the first discharge flow path 45 flows along the downwardly sloping bottom surface of the first discharge flow path 45 and is sprayed onto one side of the blade 62 via the first nozzle 451 formed at the lower end of the front surface of the first discharge flow path 45.

[0280] The bottom of the first discharge path 45 can extend obliquely in a direction intersecting 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 discharge angle of the washing water sprayed from the first nozzle 451, is 90 degrees, which maximizes the rotational force of the mixing component 60.

[0281] Furthermore, the closer the first nozzle 451 is to the edge of the blade 62 than the rotation axis 61 of the mixing component 60, the greater the rotational torque of the mixing component 60 becomes. Therefore, the formation position of the first discharge flow path 45 can be appropriately selected according to the design conditions.

[0282] Furthermore, the mixing component 60 can continuously rotate during the spraying of water from the first nozzle 451. With the first container 54 filled with powdered detergent, the mixing component 60 mixes the powdered detergent with water while rotating, dissolving the powdered detergent in the washing water. The mixing component 60 can pulverize powdered detergent that is unevenly distributed in the first container 54 or in a blocky state, and after dissolving it in water, discharge it to the rear of the detergent dispenser 50.

[0283] In detail, such as Figure 31 as well as Figure 32 As shown, the mixing component 60 rotates due to water being sprayed from the first nozzle 451. Then, as the mixing component 60 rotates, the water supplied through the first nozzle 451 and the first spray hole 463 can mix with the powdered detergent filled in the first container 54.

[0284] The centrifugal force generated by the rotation of the mixing component 60 causes the powdered detergent P adjacent to the blade 62 to move along the blade 62 in the circumferential direction of the mixing component 60. Furthermore, the powdered detergent P disposed on the blade 62 may splash due to the pressure of the water ejected from the first nozzle 451.

[0285] At this time, since the auxiliary blade 64 extends in the opposite direction to the rotation direction of the mixing component 60, it is possible to guide the powder detergent P moving along the blade 62 in the circumferential direction and the powder detergent P splashed by the sprayed water to the inner region of the mixing component 60 instead of escaping to the outside of the mixing component 60.

[0286] Therefore, the powdered detergent inside the first container 54 will not flow out of the first container 54, keeping the detergent box 50 clean. Moreover, since the powdered detergent P is continuously guided into the gap space between the blades 62, the powdered detergent P can be effectively pulverized by the rotating blades 62 and the water sprayed from the first nozzle 451, and completely dissolved in the washing water.

[0287] Furthermore, when the mixing component 60 rotates, the blades 62 and the auxiliary blades 64 can pass through the drain channel 543. Therefore, the dissolved powder detergent located between the plurality of blades 62 can naturally flow into the drain channel 543 and be discharged through the drain channel 543 to the rear of the first receiving portion 54.

[0288] Then, the dissolved detergent discharged to the rear of the detergent box 50 can be discharged into the bucket 11 via the housing outlet 321 on the lower surface 32 of the housing and the front end of the lower surface 32 of the housing.

[0289] Furthermore, the washing water flowing along the second discharge path 46 flows through the main section 461 to the extension section 462. Then, the interior of the first container 54 and the mixing component 60 can be washed by the washing water falling into the first container 54 through the first spray hole 463 of the second discharge path 46.

[0290] In detail, a portion of the washing water passing through the main section 461 can be supplied to the mixing component 60 by falling downwards through the plurality of main spray holes 464. The mixing component 60 can be washed by the water falling from the main spray holes 464.

[0291] A portion of the main spray holes 464 can be located vertically above the rotating shaft 61. Therefore, detergent adhering to the surface of the rotating shaft 61 can be washed away by water falling from the main spray holes 464. Furthermore, another portion of the main spray holes 464 can be located vertically above the blades 62. Therefore, detergent adhering to the blades 62 can be washed away by water falling from the main spray holes 464.

[0292] Washing water flowing into the extension 462 after passing through the main portion 461 can fill the extension 462 and fall downwards through the plurality of extension spray holes 465 to wash the first receiving portion 54. Specifically, the extension spray holes 465 can be located vertically above the arcuate front surface of the first receiving portion 54. In particular, the extension spray holes 465 can be configured along the front end of the first receiving portion 54.

[0293] Therefore, the washing water falling from the extended spray hole 465 can fall onto the upper end of the front surface portion of the first receiving portion 54 or the surface forming the front surface of the first receiving portion 54. Then, the washing water falling from the extended spray 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, the detergent adhering to the inner surface of the first receiving portion 54 can be washed by the washing water falling from the extended spray hole 465.

[0294] Then, the water after washing the first receiving section 54 can be discharged together with the detergent to the rear of the detergent box 50. Then, the water and detergent discharged to the rear of the detergent box 50 can be discharged into the bucket 11 through the housing outlet 321 on the lower surface 32 of the housing and the front end of the lower surface 32 of the housing.

[0295] Figure 36 This diagram illustrates the situation where washing water falls into the second receiving portion through the second spray hole formed in the flow path component.

[0296] Reference Figure 31 as well as Figure 36 Water flowing into the fourth discharge path 48 can flow forward along the fourth discharge path 48 and be supplied to the second receiving portion 55 via the second spray hole 481 formed in the fourth discharge path 48.

[0297] As an example, liquid detergent can be contained in the second receiving portion 55, which can be diluted with the washing water supplied from the second spray hole 481 and discharged to the bottom of the housing 30 via the siphon boss 551.

[0298] Specifically, a portion of the washing water flowing along the fourth discharge path 48 falls downwards from the first front hole 482. At this time, the first front hole 482 passes through the first front cover hole 571 of the receiving cover 57 and falls into front of the second receiving portion 55. It can then be mixed with liquid detergent inside the second receiving portion 55.

[0299] Furthermore, another portion of the washing water flowing along the fourth discharge path 48 falls downwards through the first rear hole 483. At this time, the washing water falling through the first rear hole 483 passes through the first rear cover hole 572 of the receiving cover 57 and falls behind the second receiving part 55.

[0300] 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 fall directly into the siphon recess 553. Thus, highly viscous liquid detergent or solidified liquid detergent accumulated in the siphon recess 553 can be easily dissolved or pulverized and discharged through siphon action.

[0301] Liquid detergent mixed with water supplied to the second receiving portion 55 can flow from the siphon recess 553 between the siphon extension 573 and the siphon protrusion 551, and be discharged into the opening at the upper end of the siphon protrusion 551 to the bottom of the detergent box 50. Then, the liquid detergent mixed with the water discharged to the bottom of the detergent box 50 can be discharged into the tub 11 through the housing outlet 321 on the lower surface 32 of the housing and the front end of the lower surface 32 of the housing.

[0302] Figure 37 This diagram shows the washing water falling into the third receiving part through the third spray hole formed in the flow path component.

[0303] Reference Figure 31 as well as Figure 37 Water flowing into the fifth discharge path 49 can flow forward along the fifth discharge path 49 and be supplied to the third receiving part 56 through the third spray hole 491 formed in the fifth discharge path 49.

[0304] As an example, a fabric softener may be contained in the third receiving portion 56, which may be discharged downward via the siphon boss 561 after being diluted in the washing water supplied from the third spray hole 491.

[0305] Specifically, a portion of the wash water flowing along the fifth discharge path 49 falls downwards from the second front hole 492. At this time, the wash water falling from the second front hole 492 passes through the second front cover hole 575 of the receiving cover 57 and falls in front of the third receiving portion 56. The wash water falling into the third receiving portion 56 can then be mixed with the fabric softener.

[0306] Furthermore, a portion of the 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 passes through the second rear cover hole 576 of the receiving cover 57 and falls behind the third receiving part 56.

[0307] 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 pass through the second rear cover hole 576 and fall directly into the siphon recess 563. Thus, highly viscous liquid detergent or solidified liquid detergent accumulated in the siphon recess 563 can be easily dissolved or pulverized and discharged through siphon action.

[0308] Fabric softener mixed with water supplied to the third receiving portion 56 can flow from the siphon recess 563 between the siphon extension 577 and the siphon protrusion 561, and be discharged into the opening at the upper end of the siphon protrusion 561 to the bottom of the detergent dispenser 50. Then, the fabric softener mixed with the water discharged to the bottom of the detergent dispenser 50 can be discharged into the tub 11 via the housing outlet 321 on the lower surface 32 of the housing and the front end of the lower surface 32 of the housing.

[0310] The rotating shaft grooves can be arranged radially with respect to the center of the rotating shaft.

[0311] The rotating shaft grooves can be configured at equal intervals.

[0312] The rotating shaft groove can be symmetrically arranged with respect to the center of the rotating shaft.

[0313] It is possible that the rotating shaft is formed such that its inner diameter becomes narrower as it extends from the lower end to the upper end, and the rotating shaft groove is formed such that its width becomes narrower as it extends upward along the inner surface of the rotating shaft.

[0314] Alternatively, a support portion may be formed protruding downward from the upper inner side of the rotating shaft, the support portion being placed on the upper end of the rotating boss, and the rotating shaft groove being symmetrically arranged with respect to the support portion.

[0315] Alternatively, an outwardly protruding portion may be formed at the lower end of the rotating shaft, and the rotating shaft groove may extend upward from the protruding portion, the protruding portion being connected to an injection gate for molding the hybrid component.

[0316] The mixing component may include auxiliary blades that extend at the extended ends of the blades in a direction intersecting the blades.

[0317] The hybrid component can be configured such that the height of the upper end of the auxiliary blade is the same as the height of the upper end of the blade connected to the rotation shaft.

[0318] The position of the blade connected to the upper end of the rotating shaft can correspond to the dividing line of the mold that moves up and down to form the hybrid component.

[0319] The washing machine provided in the proposed embodiment achieves the following effects. In the washing machine provided in the embodiment of the present invention, a rotating shaft groove for improving resin flow during injection molding can be formed at the end of the rotating shaft. By forming multiple rotating shaft grooves along the rotating shaft, the flow of resin injected into the rotating shaft can be improved. By moving the position of air traps generated during molding to the dividing line separated by the mold, air traps can be removed by venting. Therefore, poor appearance of the mixing component due to air traps can be prevented, and detergent residue in the mixing component can be prevented.

[0322] The shaft support portion may include: a support protrusion extending from the inner upper end of the rotating shaft; and a support base formed on the outer peripheral surface of the support protrusion.

[0323] Alternatively, the support base may include a plurality of support ribs that connect the outer peripheral surface of the support protrusion to the inner peripheral surface of the support shaft, the plurality of support ribs being spaced apart in the circumferential direction.

[0324] The mixing component also includes a plurality of auxiliary blades, which extend a predetermined length along the ring at their ends in the circumferential direction.

[0325] Alternatively, the plurality of auxiliary blades may extend upward from the upper surface of the ring along the end of the blade to a predetermined height, with the upper surface of the auxiliary blade located at a position lower than the upper surface of the blade.

[0326] It is possible that the blade is formed such that the closer it is to the upper side, the more it is tilted towards the direction of rotation of the rotation axis by a predetermined angle, and the side of the auxiliary blade is tilted at an angle corresponding to the tilt angle of the blade.

[0327] At least one of the following can be formed into an arc shape: the corner where the upper surface of the auxiliary blade meets the side surface, the corner where the side surface of the auxiliary blade meets the upper surface of the ring, or the corner where the upper surface of the auxiliary blade meets the blade.
