The liquid outlet waterway 20 has a water inlet end and a water outlet end. Among them, the first waterway 40A and the second waterway 50A are used for conveying fluid.

[0047] It should be noted that in the embodiment of the present application, the first waterway 40A refers to the flow path of the fluid, and does not specifically refer to the pipe structure. The second waterway 50A refers to the flow path of the fluid, and does not specifically refer to the pipe structure. The arrows in the drawing show the flow direction of the fluid.

[0048] The embodiment of the present application also provides a clothes processing equipment, and the type of clothes processing equipment is not limited, for example, it can be a washing machine, a washing and drying integrated machine and the like.

[0049] Please refer to figure 1 and figure 2, the clothes processing equipment includes a clothes processing cavity (not shown) and the detergent dispensing device 100 in any embodiment of the present application. The clothes processing cavity is used for accommodating clothes to be processed, and the water outlet end of the liquid outlet waterway 20 of the detergent dispensing device 100 communicates with the clothes processing cavity. That is, the liquid outlet waterway 20 guides the converged fluid to the clothes processing cavity through the water outlet end.

[0050] The water inlet end of the first water path 40A is connected to a water source, and the water outlet end is connected to the water inlet end of the liquid outlet path 20. The water inlet end of the second water path 50A is connected to the water source, and the water outlet end is connected to the water inlet end of the liquid outlet path 20.

[0051] It should be noted that the water source mentioned above refers to a water source for supplying water flow to the first water path 40A and the second water path 50A, such as tap water; it can also be an internal water source of the laundry treatment apparatus, such as circulating water. For example, referring to FIG. 2, the laundry treatment apparatus includes a water inlet valve 90 connected to the water source, and the first water path 40A and the second water path 50A can be connected to different water inlet valves 90 or can be connected to the same water inlet valve 90, which is not limited herein. As an optional embodiment, the laundry treatment apparatus includes a circulating pump (not shown), one of the first water path 40A and the second water path 50A is connected to the water inlet valve 90, and the other is connected to the circulating pump of the laundry treatment apparatus.

[0052] The fluid in the first water path 40A and the fluid in the second water path 50A converge in the liquid outlet path 20, and the fluid in the first water path 40A is a detergent mixed solution.

[0053] It should be noted that the detergent mixed solution mentioned in the present specification is only for convenience of description, which refers to a mixed solution in which a detergent is dissolved, and the mass percentage concentration is not limited, and it is not limited that the detergent is completely dissolved. The composition of the fluid in the second water path 50A is not limited, which can be clean water, a detergent mixed solution, or a solution added with other care components.

[0054] The form of the detergent is not limited, which can be a powder such as laundry powder, can be a laundry liquid that can flow, or can be a softener that can flow, etc.

[0055] It can be understood that the first water path 40A delivers the detergent mixed solution into the liquid outlet path 20, and the second water path 50A also delivers the fluid into the liquid outlet path 20, the first water path 40A and the second water path 50A converge in the liquid outlet path 20, so that the two fluids are mixed, and after mixing, they are discharged from the water outlet end of the liquid outlet path 20 and enter the laundry treatment cavity to participate in the laundry treatment.

[0056] The second water path 50A does not flow through the first drain, and the detergent mixed solution delivered by the first water path 40A can intersect with the fluid of the second water path 50A in the liquid outlet path 20, which can further promote the dilution and dissolution of the detergent, improve the mixing uniformity of the detergent and water, thereby improving the utilization efficiency of the detergent and improving the cleaning ratio.

[0057] It is to be noted that the liquid outlet waterway 20 refers to a flow path between a position where the first waterway 40A and the second waterway 50A are mixed and a position where the mixed fluid leaves the liquid outlet waterway 20. The water inlet end of the liquid outlet waterway 20 refers to a position where the fluid in the first waterway 40A leaves the first waterway 40A and enters the liquid outlet waterway 20 and a position where the fluid in the second waterway 50A leaves the second waterway 50A and enters the liquid outlet waterway 20. The water outlet end of the liquid outlet waterway 20 refers to a position where the mixed fluid in the liquid outlet waterway 20 leaves the liquid outlet waterway 20.

[0058] For example, in some embodiments, referring to FIG. 6, the liquid outlet waterway 20 includes a mixing space 20a, and the wall surface of the mixing space 20a is provided with two ports 20b. The fluid in the first waterway 40A enters the mixing space 20a from one of the two ports 20b, and the fluid in the second waterway 50A enters the mixing space 20a from the other port 20b. The two ports 20b can be considered as the water outlet ends of the first waterway 40A and the second waterway 50A and also as the water inlet end of the liquid outlet waterway 20. The outlet end (not shown in the figure) of the liquid outlet waterway is arranged on the wall surface of the mixing space 20a.

[0059] In other embodiments, referring to FIG. 7, the liquid outlet waterway 20 includes a mixing space 20a, and the wall surface of the mixing space 20a is provided with one port 20b. The fluid in the first waterway 40A enters the mixing space 20a from the port 20b, and the water outlet end of the second waterway 50A is arranged at a position in the mixing space 20a. The port 20b of the mixing space 20a can be considered as the water outlet end of the first waterway 40A and also as the water inlet end of the liquid outlet waterway 20. The water outlet end of the second waterway 50A can be considered as another water inlet end of the liquid outlet waterway 20. The outlet end (not shown in the figure) of the liquid outlet waterway 20 is arranged on the wall surface of the mixing space.

[0060] In other embodiments, referring to FIG. 8, the laundry treating apparatus includes a first tubular structure 1001 and a second tubular structure 1002. The liquid outlet waterway 20 includes a mixing space 20a, and the mixing space 20a of the liquid outlet waterway 20 is formed by a portion of the first tubular structure 1001, that is, the mixing space 20a of the liquid outlet waterway 20 is formed by the first tubular structure 1001 itself. The portion of the first tubular structure 1001 located upstream of the mixing space 20a defines a portion of the first waterway 40A. A portion of the second waterway 50A is formed by the second tubular structure 1002. The water outlet end of the second tubular structure 1002 is located in the internal space of the mixing space 20a formed by the first tubular structure 1001. The fluid in the second waterway 50A flows out of the water outlet end of the second tubular structure 1002 and converges with the fluid in the first waterway 40A in the mixing space 20a formed by the first tubular structure 1001.

[0061] The water outlet section 1003 formed upstream of the mixing space 20a adjacent to the first tubular structure 1001 can be considered as the water outlet end of the first waterway 40A, and also as one water inlet end of the liquid outlet waterway 20. The water outlet end of the second tubular structure 1002 can be considered as another water inlet end of the liquid outlet waterway 20. The water outlet end (not shown in the figure) of the liquid outlet waterway 20 is arranged on the first tubular structure 1001.

[0062] The detergent feeding device provided by the embodiments of the present application has a flow rate difference between the water outlet ends of the first waterway 40A and the second waterway 50A. The flow rate of the water outlet end of the first waterway 40A is greater than that of the water outlet end of the second waterway 50A, or in another embodiment, the flow rate of the water outlet end of the first waterway 40A is greater than that of the water outlet end of the second waterway 50A. That is, there is a flow rate difference between the water outlet ends of the first waterway 40A and the second waterway 50A. The water outlet end of the first waterway 40A refers to the position where the detergent mixed solution in the first waterway 40A exits the first waterway 40A, and can also be understood as the junction of the first waterway 40A and the liquid outlet waterway 20. The water outlet end of the second waterway 50A refers to the position where the fluid in the second waterway 50A exits the second waterway 50A, and can also be understood as the junction of the second waterway 50A and the liquid outlet waterway 20.

[0063] It can be understood that the flow rates of the two fluids entering the liquid outlet waterway 20 are fast and slow. The fluid with a faster flow rate can impact and disturb the fluid with a slower flow rate, so that the two fluids can be mixed well when they meet, and the dissolution of the detergent is further promoted.

[0064] The way to make the flow rate difference between the water outlet ends of the first waterway 40A and the second waterway 50A is not limited, for example, the two waterways can be connected to two water inlet valves 90 with different water outlet speeds respectively.

[0065] In some embodiments, the water outlet end of the first waterway 40A or the second waterway 50A is provided with a reduced-diameter section 22. For example, in an embodiment, the reduced-diameter section 22 directly forms the water outlet end of the first waterway 40A or the second waterway 50A, or in another embodiment, the reduced-diameter section 22 is connected with a constant-diameter section and / or an enlarged-diameter section, and the constant-diameter section and / or the enlarged-diameter section forms the water outlet end of the first waterway 40A or the second waterway 50A. Hereinafter, the second waterway 50A provided with the reduced-diameter section 22 is described.

[0066] It should be noted that in the direction of the movement of the fluid, the flow area of the fluid in the reduced-diameter section described above decreases, the flow area of the fluid in the constant-diameter section described above is basically unchanged, and the flow area of the fluid in the enlarged-diameter section described above increases.

[0067] The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area when the fluid is ejected, thereby achieving a better mixing effect. Meanwhile, the reduced diameter section 22 enables the water outlet end of the second water channel 50A to have a relatively large ejection speed, thereby enabling the surrounding area to have a significant negative pressure, so that the fluid at the water outlet end of the first water channel 40A is sucked and mixed with the fluid in the second water channel 50A under the action of the negative pressure, thereby improving the mixing and foaming effect.

[0068] In some embodiments, the lengths of the constant diameter section and the enlarged diameter section along the extension length of the second water channel 50A are less than or equal to the length of the reduced diameter section 22 along the extension length of the second water channel 50A. Since the longer the flow path of the fluid, the more obvious the energy loss, limiting the length of the constant diameter section and / or the enlarged diameter section can reduce the loss of the circumferential velocity component and the impact force of the fluid after flowing out of the reduced diameter section 22.

[0069] Referring to FIG. 4, the detergent dispensing device 100 further comprises a turbulence structure 21 arranged in the first water channel 40A or the second water channel 50A, which is used to provide the fluid in the second water channel 50A with a circumferential velocity component. That is, the turbulence structure 21 can be arranged in the first water channel 40A or the second water channel 50A. Hereinafter, the arrangement of the turbulence structure 21 in the second water channel 50A is described.

[0070] The above-mentioned provision of the circumferential velocity component refers to that the component of the speed direction of the fluid in the second water channel 50A after passing through the turbulence structure 21 in the circumferential direction of the second water channel 50A is not zero, and the circumferential direction of the second water channel 50A is perpendicular to the extension direction of the second water channel 50A.

[0071] After the fluid passes through the turbulence structure 21, the state of the fluid changes, and the fluid has a tendency to spread along the circumferential direction, thereby forming multiple streams of fluid flowing in different directions, so that the fluid enters the liquid outlet water channel 20 and is better mixed with the fluid in the liquid outlet water channel 20, thereby improving the mixing efficiency. Also, the fluid ejected from the water outlet end of the liquid outlet water channel 20 can be roughly in a conical shape, thereby having a wider radiation range and a better visual effect.

[0072] It can be understood that the turbulence structure 21 can also increase the flow rate of the fluid by limiting the flow area of the region of the second water channel 50A in which the turbulence structure 21 is arranged. In this way, the speeds of the two streams of fluid entering the liquid outlet water channel 20 are more different, thereby further promoting the dissolution of the detergent.

[0073] Exemplarily, the turbulence structure 21 comprises one or more spiral blades for guiding the spiral movement of the fluid. The spiral blade refers to a blade having a spiral line shape, and the blade extends in the spiral direction. After the fluid passes through the spiral blade, the fluid moves in a spiral shape and has a circumferential velocity component. The spiral blade structure is simple, has a good turbulence effect on the fluid, and has small resistance, thereby reducing the energy loss of the fluid when passing through.

[0074] In some embodiments, the spiral vane is arranged in the second waterway 50A, the outer edge of the spiral vane along the spiral direction is connected with the inner wall of the second waterway 50A, and the inner edge of the spiral vane along the spiral direction is arranged in a spaced manner with the inner wall of the second waterway 50A, that is, there is a gap between the inner edge of the spiral vane and the inner wall of the second waterway 50A, so that the inner wall of the second waterway 50A provides a connection support for the spiral vane.

[0075] In some embodiments, the second waterway 50A is provided with the turbulent structure 21 and the reduced-diameter section 22, and the reduced-diameter section 22 is located downstream of the turbulent structure 21. The fluid sequentially passes through the turbulent structure 21 and the reduced-diameter section 22 and is then sprayed out of the laundry treatment cavity in a fluid having a conical shape.

[0076] In this embodiment, the fluid in the first waterway 40A is a laundry detergent mixed solution or a laundry powder mixed solution, especially a laundry powder mixed solution. Since the laundry powder is a powdery detergent, it is more likely to be blocked and left than the laundry liquid, which may reduce the reliability of the first waterway 40A. If the turbulent structure 21 and the reduced-diameter section 22 are arranged in the first waterway 40A, the above problems will be more likely to occur. The fluid in the second waterway 50A is water, that is, the second waterway 50A is used to transport water from a water source. The turbulent structure 21 and the reduced-diameter section 22 are arranged in the second waterway 50A. The water flows through the second waterway 50A and is discharged at a high speed from the water outlet end. The laundry powder mixed solution in the water outlet end of the first waterway 40A is impacted, fully mixed, and a large amount of foam is generated. Finally, the fluid is sprayed out of the water outlet end of the liquid outlet waterway 20 in a substantially conical shape and has a large amount of foam.

[0077] Exemplarily, referring to FIG. 2, the detergent dispensing device 100 includes a detergent box 30 having a first water outlet for discharging a detergent mixed solution, and the first waterway 40A flows through the first water outlet. The first water outlet can be formed by the detergent box 30 itself, or can be formed by the water outlet end of a waterway structure additionally arranged on the top, side, or bottom of the detergent box 30.

[0078] It should be noted that the first waterway 40A flows through the detergent dispensing cavity and the first water outlet, that is, the detergent dispensing cavity and the first water outlet constitute part of the first waterway 40A.

[0079] Referring to FIG. 3, the first water outlet is higher than the water inlet end of the liquid outlet waterway 20 in the gravity direction G, so that the detergent mixed solution in the first waterway 40A and the fluid in the second waterway 50A converge in the liquid outlet waterway 20 under the action of gravity.

[0080] Due to the height difference between the first drain and the water inlet end of the liquid outlet waterway 20, the fluid passing through the first drain flows under the action of gravity and mixes with the fluid in the second waterway 50A at a certain speed. In this way, the gravitational potential energy can be used to mix with the fluid in the second waterway 50A, without the need for additional electric devices such as water pumps, so that power-free mixing can be achieved, costs can be saved, the structure can be simplified, and the working stability can be enhanced. The acceleration effect of gravity enables the detergent mixed solution in the first waterway 40A to flow more smoothly into the liquid outlet waterway 20.

[0081] It should be noted that the liquid outlet waterway 20 can be arranged directly below the first drain or obliquely below the first drain, as long as the water inlet end of the liquid outlet waterway 20 has a height difference with the first drain in the gravity direction G.

[0082] In some embodiments, referring to FIG. 3, any position of the detergent box 30 is higher than the water inlet end of the liquid outlet waterway 20 in the gravity direction. The detergent mixed solution in the detergent box 30 has a higher gravitational potential energy than the mixed solution in the liquid outlet waterway 20, and the acceleration effect of gravity is more obvious when the detergent mixed solution is discharged through the first drain.

[0083] In some embodiments, any position of the first waterway 40A is not lower than the liquid outlet waterway 20 in the gravity direction. That is, the junction of the liquid outlet waterway 20 and the first waterway 40A is located at the lowest point of the first waterway 40A, so that more energy is converted into kinetic energy of the water flow when the detergent mixed solution in the first waterway 40A converges at the liquid outlet waterway 20, thereby improving the flow speed.

[0084] In some embodiments, referring to FIG. 3, any position of the second waterway 50A is not lower than the water inlet end of the liquid outlet waterway 20 in the gravity direction G. That is, the junction of the liquid outlet waterway 20 and the second waterway 50A is located at the lowest point of the second waterway 50A, so that more energy is converted into kinetic energy of the water flow when the fluid in the second waterway 50A converges at the liquid outlet waterway 20, thereby improving the flow speed.

[0085] For example, the detergent dispensing device 100 includes a dispenser box (not shown) arranged in the detergent box 30. The dispenser box has a detergent dispensing cavity. The water flow of the first waterway 40A flows through the detergent dispensing cavity and the first drain. It should be noted that the detergent in the detergent dispensing cavity can flow to the first drain under the action of water.

[0086] In some embodiments, the dispenser box is arranged in the detergent box 30 in a drawable manner, for example, the dispenser box is at least partially drawn out of the detergent box 30 to the outside of the detergent box 30, and the user can put the detergent into the detergent dispensing cavity.

[0087] In an embodiment, the detergent box 30 further has a mixing chamber for receiving the fluid flowing through the detergent dispensing chamber, and the first drain is arranged on the wall of the mixing chamber. That is, the mixed solution with detergent flows into the mixing chamber and is discharged from the first drain.

[0088] In an embodiment, the mixing chamber is arranged below the dispenser box, and the mixed solution with detergent flows from the detergent dispensing chamber of the dispenser box to the mixing chamber below the dispenser box and is discharged from the first drain.

[0089] In some embodiments, referring to FIG. 3, the detergent box 30 further has an overflow chamber for receiving the mixed solution with detergent overflowing from the mixing chamber, and a second drain 30a for discharging the mixed solution with detergent in the overflow chamber from the detergent box 30.

[0090] In this embodiment, when the water level in the mixing chamber is not higher than the overflow water level, the water in the mixing chamber is discharged from the first drain and flows to the liquid outlet waterway 20. When the water level in the mixing chamber is higher than the overflow water level, the excess water overflows into the overflow chamber and is discharged from the second drain 30a. That is, the detergent box 30 preferentially discharges water from the first drain, and the second drain 30a serves as a safety protection function to timely discharge the excess water in the mixing chamber.

[0091] In an embodiment, the water flow cross-sectional area of the second drain 30a is greater than that of the first drain. That is, under the condition of sufficient water volume, the water discharge flow rate of the second drain 30a is greater than that of the first drain.

[0092] Since the water flow cross-sectional area of the first drain is small, the water discharge flow rate of the first drain is relatively small. The second drain 30a and the overflow chamber can timely discharge the mixed solution with detergent or water flow in the first waterway 40A under the condition of overflow, thereby reducing the water flow congestion in the detergent box 30 and serving as a safety protection function.

[0093] In some embodiments, referring to FIG. 2, the detergent dispensing device 100 includes a first pipeline 41 and a second pipeline 42. One end of the first pipeline 41 is connected to an external water source, for example, a water inlet valve 90, and the other end of the first pipeline 41 is connected to the water inlet end of the detergent box 30 for guiding the water flow into the detergent box 30. One end of the second pipeline 42 is connected to the first drain, and the other end of the second pipeline 42 is connected to the liquid outlet waterway 20 for guiding the fluid discharged from the first drain to the liquid outlet waterway 20. In this embodiment, the space in the first pipeline 41, the space in the second pipeline 42, and at least part of the space in the detergent box 30 together constitute at least part of the first waterway 40A.

[0094] In some embodiments, referring to FIG. 2, the detergent dispensing device 100 comprises a third pipeline 50, one end of the third pipeline 50 is connected to a water source, and the other end of the third pipeline 50 is connected to the liquid outlet water path 20, and is used to guide the water from the water source to the liquid outlet water path 20. In this embodiment, the space in the third pipeline 50 can independently define a second water path 50A, or the space in the third pipeline 50 defines part of the second water path 50A.

[0095] It should be noted that the first pipeline 41 described above can be a complete pipe body or can be connected by multiple pipe bodies, which is not limited here.

[0096] The second pipeline 42 described above can be a complete pipe body or can be connected by multiple pipe bodies, which is not limited here.

[0097] The third pipeline 50 described above can be a complete pipe body or can be connected by multiple pipe bodies, which is not limited here.

[0098] Exemplarily, as shown in FIG. 3, the third pipeline 50 can be integrally arranged outside the detergent box 30; or part of the third pipeline 50 is integrated on the shell of the detergent box 30, that is, part of the shell of the detergent box 30 constitutes part of the third pipeline 50; or the third pipeline 50 is a pipeline structure penetrating through the detergent box 30.

[0099] In some embodiments, the laundry treating apparatus comprises a drum assembly 10, and the drum assembly 10 comprises an inner drum.

[0100] Exemplarily, as shown in FIG. 1, the drum assembly 10 further comprises an outer tub 11, and the inner drum is rotatably arranged in the outer tub 11. The outer tub 11 is used to hold water for laundry washing, and the inner drum is used to hold laundry. In this embodiment, the inner drum holds water through the outer tub 11, and the inner drum can also be referred to as a perforated inner drum. In other embodiments, the inner drum holds water by itself, and can also be referred to as a non-perforated inner drum. The outer drum 11 can be arranged outside the inner drum, or can not be arranged outside the inner drum.

[0101] It can be understood that in some embodiments, the drum assembly 10 can only have the inner drum and does not have the outer tub 11 described above. In this embodiment, the inner drum is a non-perforated inner drum, and the inner drum can hold water by itself.

[0102] Exemplarily, referring to FIG. 1, the laundry treating apparatus further comprises a door body, a cabinet, and a door seal ring 60 disposed at the front side of the drum assembly 10. The drum assembly 10 is disposed in the cabinet. The cabinet is provided with an opening in communication with the interior of the drum assembly 10, and the door body is used to open or close the opening. The door seal ring 60 is used to seal the gap between the drum assembly 10 and the opening of the cabinet, and the door body sealingly abuts on the door seal ring 60 when the door body closes the opening. Thus, the communication space formed by the door body, the door seal ring 60 and the interior of the drum assembly 10 constitutes the laundry treating cavity.

[0103] In some embodiments, referring to FIG. 1, the door seal ring 60 has a mounting opening, and the water outlet end of the liquid outlet waterway 20 penetrates through the mounting opening of the door seal ring 60 and extends to the radial inner side of the door seal ring 60. In this way, the water outlet end of the liquid outlet waterway 20 can directly discharge the mixed liquid of the first waterway 40A and the second waterway 50A into the laundry treating cavity.

[0104] The above-mentioned discharge into the laundry treating cavity means that the mixed liquid of the first waterway 40A and the second waterway 50A discharged by the liquid outlet waterway 20 does not need to be guided by other structures, but is directly discharged into the laundry treating cavity under the action of the gravity and pressure of the fluid itself. In this way, the mixed liquid can be sprayed to wet the laundry, which can improve the washing effect.

[0105] In some embodiments, the water outlet end of the liquid outlet waterway 20 is inclined to discharge water towards the lower rear of the laundry treating cavity, which facilitates the water to be sprayed to cover a large range of laundry in the laundry treating cavity.

[0106] In some embodiments, the outer tub 11 has a water inlet opening, and the second drain port 30a is in communication with the water inlet opening and is used to guide the overflow of the detergent mixed solution in the detergent box 30 to the outer tub 11, which can play an auxiliary water inlet role. Exemplarily, as shown in FIG. 1, the laundry treating apparatus further comprises a water outlet pipeline 70 connected between the second drain port 30a and the water inlet opening.

[0107] In some embodiments, referring to FIG. 2, the laundry treating apparatus comprises a water inlet valve 90, and the water inlet valve 90 has a first outlet 90a. The first waterway 40A and the second waterway 50A are both in communication with the first outlet 90a. A water source supplies water to the laundry treating apparatus through the water inlet valve 90, and the first waterway 40A and the second waterway 50A are both connected to the first outlet 90a of the water inlet valve 90. In this way, the installation of the first waterway 40A and the second waterway 50A can be facilitated, and the setting of the water inlet valve 90 can be simplified, thereby saving costs.

[0108] Exemplarily, as shown in FIG. 2, the water inlet valve 90 further has a second outlet 90b, which can be used to supply water to other pipelines.
