[0044] Please refer to Figure 1 and Figure 2, the laundry treating apparatus comprises a laundry treating cavity and the detergent feeding device 100 in any embodiment of the present application. The water outlet end of the liquid outlet water path 20 of the detergent feeding device 100 is communicated with the laundry treating cavity.

[0045] The liquid outlet water path 20 has a water inlet end and a water outlet end. Please refer to Figure 2 to Figure 8, the arrow dotted lines in the drawings of the present specification all show the liquid flow direction.

[0046] The first water path 40A is communicated with the water source and the water inlet end of the liquid outlet water path 20, and the second water path 50A is communicated with the water source and the water inlet end of the liquid outlet water path 20.

[0047] The fluid in the first water path 40A and the fluid in the second water path 50A converge in the liquid outlet water path 20, and the fluid in the first water path 40A is a detergent mixed solution.

[0048] It should be noted that the above water source refers to a water source for supplying fluid to the first water path 40A and the second water path 50A, for example, tap water; or can be an internal water source of the laundry treating apparatus, for example, circulating water. Exemplarily, please refer to Figure 2, the laundry treating apparatus comprises a water inlet valve 90, the water inlet valve 90 is connected with the water source, the first water path 40A and the second water path 50A can be connected with different water inlet valves 90, or can be connected with the same water inlet valve 90, which is not limited herein. As an optional embodiment, the laundry treating apparatus comprises a circulating pump (not shown), one of the first water path 40A and the second water path 50A is connected with the water inlet valve 90, and the other is connected with the circulating pump of the laundry treating apparatus.

[0049] It should be noted that the detergent mixed solution mentioned in the present specification refers to a solution in which a detergent is dissolved, and the mass percentage concentration of the solution is not limited. Of course, the detergent mixed solution is not limited to the case where the detergent is completely dissolved. The fluid of the second waterway 50A is not limited, and can be clean water, a detergent mixed solution, or a solution in which other care components are added.

[0050] The form of the detergent is not limited, and can be a powder such as a laundry powder, a laundry liquid that can flow, a softener that can flow, or the like.

[0051] Exemplarily, the detergent dispensing device 100 comprises a detergent supply assembly having a first water outlet for discharging the detergent mixed solution, and the first waterway 40A is connected to the water source, the first water outlet, and the water inlet end of the liquid outlet waterway 20. The detergent supply assembly comprises the detergent box 30, and the first water outlet can be formed by the detergent box 30 itself or the water outlet end of the waterway structure additionally arranged on the top, side, or bottom of the detergent box 30.

[0052] Exemplarily, referring to FIG. 2, the detergent dispensing device comprises the detergent box 30 and a dispenser box (not shown) arranged in the detergent box. The dispenser box is arranged in the detergent box 30. The dispenser box is formed with a detergent dispensing cavity, and the detergent box 30 has a first water outlet. The first waterway 40A flows through the detergent dispensing cavity and the first water outlet. The first waterway 40A introduces the fluid of the water source into the detergent dispensing cavity, mixes with the detergent, forms the detergent mixed solution, and discharges from the detergent box 30 through the first water outlet.

[0053] In some embodiments, the dispenser box is arranged in the detergent box 30 in a pullable manner, for example, the dispenser box is pulled out from the detergent box 30 at least partially in a horizontal direction to the outside of the detergent box 30.

[0054] It can be understood that after flowing through the first water outlet, the first waterway 40A carrying the detergent mixed solution continues to flow into the liquid outlet waterway 20, and the second waterway 50A enters the liquid outlet waterway 20. The first waterway 40A and the second waterway 50A converge in the liquid outlet waterway 20, so that the two fluids are mixed. After mixing, the mixed solution is discharged from the water outlet end of the liquid outlet waterway 20 and enters the clothes treatment cavity.

[0055] The second waterway 50A is directly connected to the water source, and the detergent carried by the first waterway 40A can be further diluted and dissolved by the fluid of the second waterway 50A in the liquid outlet waterway 20. In this way, the dissolution of the detergent can be further promoted before the detergent enters the clothes treatment cavity, the mixing uniformity of the detergent and water is improved, and thus the utilization efficiency of the detergent and the cleaning ratio are improved.

[0056] It should be noted that in the embodiments of the present application, the first waterway 40A refers to the fluid flow path and does not specifically refer to a pipe structure. The second waterway 50A refers to the fluid flow path and does not specifically refer to a pipe structure.

[0057] It should be noted that the water inlet end of the liquid outlet waterway 20 refers to the position where the fluid in the first waterway 40A exits the first waterway 40A and enters the liquid outlet waterway 20, and the position where the fluid in the second waterway 50A exits the second waterway 50A and enters the liquid outlet waterway 20. The water outlet end of the liquid outlet waterway 20 refers to the position where the fluid in the liquid outlet waterway 20 exits 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, 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. Both of the two ports 20b can be considered as the water outlet end of the first waterway 40A and the second waterway 50A, and also as the water inlet end of the liquid outlet waterway 20, and the outlet end of the liquid outlet waterway 20 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, 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 extends to a certain 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, and the outlet end of the liquid outlet waterway is arranged on the wall surface of the mixing space 20a.

[0060] In some other embodiments, referring to FIG. 8, the laundry treating apparatus includes a first tubular structure 1001 and a second tubular structure 1002. At least a portion of the second tubular structure 1002 extends into the interior of the first tubular structure 1001. The liquid outlet waterway 20 includes a mixing space 20a, which is formed by a portion of the first tubular structure 1001, i.e., the mixing space 20a of the liquid outlet waterway is formed by the first tubular structure 1001 itself. The portion of the first tubular structure 1001 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 interior space of the mixing space 20a formed by the first tubular structure 1001, and the fluid in the second waterway 50A flows out of the water outlet end of the second tubular structure 1002 and mixes with the fluid in the first waterway 40A in the mixing space 20a formed by the first tubular structure 1001. The water outlet cross section 1003 adjacent to the upstream of the mixing space 20a formed by 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, and the water outlet end of the second tubular structure 1002 can be considered as another water inlet end of the liquid outlet waterway 20, and the water outlet end of the liquid outlet waterway is provided on the first tubular structure 1001.

[0061] Referring to FIG. 4, the detergent feeding device 100 further includes a turbulence structure 21, which is provided in the first waterway 40A or the second waterway 50A and is configured to provide a circumferential velocity component to the fluid in the second waterway 50A. That is, the turbulence structure 21 can be provided in the first waterway 40A or the second waterway 50A. Hereinafter, the case where the turbulence structure 21 is provided in the second waterway 50A is described.

[0062] The above-mentioned provision of the circumferential velocity component means that the fluid in the second waterway 50A after passing through the turbulence structure 21 has a non-zero circumferential component of the velocity direction of the fluid in the second waterway 50A, and the circumferential direction of the second waterway 50A is perpendicular to the extension direction of the second waterway 50A.

[0063] After the fluid passes through the turbulence structure 21, the state of the fluid changes and has a tendency to spread along the circumferential direction, so that a plurality of fluid streams having different flow directions are formed, which can enter the liquid outlet waterway 20 and better mix with the fluid in the liquid outlet waterway 20, thereby improving the mixing efficiency. In addition, the fluid sprayed from the water outlet end of the liquid outlet waterway 20 can be roughly in a conical shape, so that the radiation range is wider and the visual effect is better.

[0064] 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 waterway 50A in which the turbulence structure 21 is located. In this way, the two fluid streams entering the liquid outlet waterway 20 have a greater difference in velocity, thereby further promoting the dissolution of the detergent.

[0065] Exemplarily, the turbulence structure 21 comprises one or more helical blades for guiding the fluid to move helically. The helical blade refers to a blade with a helical line shape, and the blade extends in a helical direction. After passing through the helical blade, the fluid presents a helical motion with a circumferential velocity component. The helical 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.

[0066] In some embodiments, the helical blade is arranged in the second water channel 50A, and an outer edge of the helical blade in the helical direction is connected to the inner wall of the second water channel 50A, and an inner edge of the helical blade in the helical direction is arranged in a spaced manner with the inner wall of the second water channel 50A, that is, there is a gap between the inner edge of the helical blade and the inner wall of the second water channel 50A, so that the inner wall of the second water channel 50A provides a connection support for the helical blade.

[0067] In some embodiments, the water outlet end of the first water channel 40A or the second water channel 50A is provided with a reduced diameter section 22. Exemplarily, in one embodiment, the reduced diameter section 22 directly forms the water outlet end of the first water channel 40A or the second water channel 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 water channel 40A or the second water channel 50A.

[0068] It should be noted that, along the movement direction of the fluid, the flow area of the fluid in the above-mentioned reduced diameter section decreases, the flow area of the fluid in the above-mentioned constant diameter section is basically unchanged, and the flow area of the fluid in the above-mentioned enlarged diameter section increases.

[0069] The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area when the fluid is sprayed out. Exemplarily, the second water channel 50A is provided with the reduced diameter section 22, and the fluid of the second water channel 50A sprayed out from the reduced diameter section 22 has a large impact force on the fluid at the water outlet end of the first water channel 40A, thereby having a good mixing effect.

[0070] At the same time, the reduced diameter section 22 makes the water outlet end of the second water channel 50A have a large jet speed, can generate a significant negative pressure in a relatively large surrounding area, so that the fluid at the water outlet end of the first water channel 40A is sucked and mixed with the fluid of the second water channel 50A under the action of the negative pressure, thereby improving the mixing and foaming effect.

[0071] In some embodiments, the length of the constant diameter section and the enlarged diameter section along the extension length of the second water channel 50A is 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 from the reduced diameter section 22.

[0072] In some embodiments, the second water channel 50A is provided with the turbulence structure 21 and the reduced-diameter section 22, and the reduced-diameter section 22 is located downstream of the turbulence structure 21. The fluid sequentially passes through the turbulence structure 21 and the reduced-diameter section 22, and is sprayed out of the washing machine treatment cavity in a fluid with a conical shape.

[0073] In this embodiment, the fluid in the first water channel 40A is a laundry detergent mixed solution or a laundry powder mixed solution, and in particular, 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 detergent, which may reduce the reliability of the first water channel 40A. If the turbulence structure 21 and the reduced-diameter section 22 are arranged in the first water channel 40A, the above problems are more likely to occur. The fluid in the second water channel 50A is water, that is, the second water channel 50A is used to transport water from a water source. The turbulence structure 21 and the reduced-diameter section 22 are arranged in the second water channel 50A. The water flows through the second water channel 50A and is sprayed out of the water outlet at a high speed. The laundry powder mixed solution at the water outlet of the first water channel 40A is impacted, fully mixed, and a large amount of foam is generated. Finally, the fluid is sprayed out of the water outlet of the liquid outlet water channel 20 in a substantially conical shape, and has a large amount of foam.

[0074] In some embodiments, referring to FIG. 2, the detergent feeding device 100 includes a first pipe 41 and a second pipe 42. One end of the first pipe 41 is connected to a water source, for example, a water inlet valve 90. The other end of the first pipe 41 is connected to a water inlet end of the detergent box 30, and is used to guide the fluid into the detergent box 30. One end of the second pipe 42 is connected to the first drain port, and the other end is connected to the liquid outlet water channel 20, and is used to guide the fluid discharged from the first drain port to the liquid outlet water channel 20. In this embodiment, the space in the first pipe 41, the space in the second pipe 42, and part of the space in the detergent box 30 together constitute at least part of the first water channel 40A.

[0075] In some embodiments, referring to FIG. 2, the detergent feeding device 100 includes a third pipe 50. One end of the third pipe 50 is connected to a water source, and the other end is connected to the liquid outlet water channel 20. The space in the third pipe 50 can independently define the second water channel 50A, or the space in the third pipe 50 defines part of the second water channel 50A.

[0076] It should be noted that the first pipe 41 described above can be a complete pipe body or can be connected by multiple pipe bodies, which is not limited here.

[0077] The second pipe 42 described above can be a complete pipe body or can be connected by multiple pipe bodies, which is not limited here.

[0078] The third pipe 50 described above can be a complete pipe body or can be connected by multiple pipe bodies, which is not limited here.

[0079] Exemplarily, as shown in FIG. 2, the third pipeline 50 can be integrally arranged outside the detergent box 30; or, a 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 a part of the third pipeline 50; or, the third pipeline 50 is a pipeline structure penetrating through the detergent box 30.

[0080] In some embodiments, referring to FIG. 3, the first drain 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 is mixed with the fluid in the second waterway 50A in the liquid outlet waterway 20 under the action of gravity.

[0081] 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 at a speed under the action of gravity and is mixed with the fluid in the second waterway 50A. In this way, the gravitational potential energy can be used to mix with the fluid in the second waterway 50A, without the need to set an additional electric device such as a water pump, so that power-free mixing can be realized, cost can be saved, the structure can be simplified, and the working stability can be enhanced.

[0082] 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.

[0083] 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 G. The detergent mixed solution in the detergent box 30 has a higher gravitational potential energy than the liquid outlet waterway 20, and the accelerating effect of gravity is more obvious when the detergent mixed solution is discharged through the first drain.

[0084] In some embodiments, any position of the first waterway 40A 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 first waterway 40A is located at the lowest point of the first waterway 40A, so that the energy loss of the detergent mixed solution in the first waterway 40A is less when the detergent mixed solution is mixed in the liquid outlet waterway 20.

[0085] In some embodiments, 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 the energy loss of the fluid in the second waterway 50A is less when the fluid is mixed in the liquid outlet waterway 20.

[0086] Exemplarily, the flow rate at the end of the first waterway 40A is less than the flow rate at the end of the second waterway 50A. Here, the end of the first waterway 40A refers to the position at which the fluid 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 end of the second waterway 50A refers to the position at which 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.

[0087] The fluid with a slower flow rate from the first waterway 40A and the fluid with a faster flow rate from the second waterway 50A are mixed together in the liquid outlet waterway 20, which can further promote the dissolution of the detergent.

[0088] In some embodiments, referring to FIG. 1, the laundry treating apparatus includes a drum assembly 10 including an inner drum (not shown). Exemplarily, the drum assembly 10 further includes an outer tub 11, and the inner drum is rotatably arranged in the outer tub 11. The outer tub 11 is configured to hold water for laundry washing, and the inner drum is configured 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 or can not be arranged outside the inner drum.

[0089] It can be understood that, in some embodiments, the drum assembly 10 can only include the inner drum without the outer tub 11 described above. In this embodiment, the inner drum is a non-perforated inner drum, and the inner drum is capable of holding water by itself.

[0090] Exemplarily, referring to FIG. 1, the laundry treating apparatus further includes a door body (not shown), a cabinet (not shown), and a door seal ring 60 arranged at the front side of the drum assembly 10. The drum assembly 10 is arranged 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 configured to open or close the opening. The door seal ring 60 is configured to seal the gap between the drum assembly 10 and the opening of the cabinet. When the door body closes the opening, the door body sealingly abuts against the door seal ring 60, so that the communication space formed by the door body, the door seal ring 60, and the interior of the drum assembly 10 constitutes a laundry treating cavity.

[0091] 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 is directly capable of pouring the mixed liquid of the first waterway 40A and the second waterway 50A into the laundry treating cavity.

[0092] The direct dispensing into the laundry treatment cavity means that the mixed liquid from the first water path 40A and the second water path 50A of the liquid outlet water path 20 is directly dispensed into the laundry treatment cavity without being guided by other structures under the action of the gravity and the fluid pressure of the fluid. In this way, the mixed liquid can be sprayed to wet the laundry, thereby improving the washing effect.

[0093] In some embodiments, the water outlet end of the liquid outlet water path 20 is inclined towards the lower rear of the laundry treatment cavity, so that the sprayed water can cover a large range of the laundry in the laundry treatment cavity.

[0094] In an exemplary embodiment, the detergent box 30 further has a mixing cavity for receiving the fluid flowing through the detergent dispensing cavity, and the first drain is arranged on the cavity wall of the mixing cavity. That is, the mixed liquid mixed with the detergent enters the mixing cavity and is discharged from the first drain.

[0095] In an exemplary embodiment, the mixing cavity is located below the dispenser box, and the detergent mixed solution flows from the detergent dispensing cavity of the dispenser box to the mixing cavity below the dispenser box and is discharged from the first drain.

[0096] In some embodiments, referring to FIG. 3, the detergent box further has an overflow cavity for receiving the detergent mixed solution overflowing from the mixing cavity and a second drain 30a for discharging the detergent mixed solution in the overflow cavity from the detergent box 30.

[0097] In this embodiment, when the water level in the mixing cavity is not higher than the overflow water level, the fluid in the mixing cavity is discharged from the first drain and flows to the liquid outlet water path 20. When the water level in the mixing cavity is higher than the overflow water level, the excess water overflows into the overflow cavity and is discharged from the second drain 30a. That is, the detergent box 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 cavity.

[0098] In an exemplary embodiment, the fluid cross-sectional area of the second drain 30a is greater than that of the first drain, that is, under the condition that the water volume is sufficient, the water discharge flow rate of the second drain 30a is greater than that of the first drain.

[0099] Since the fluid 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 cavity can timely discharge the fluid of the first water path 40A in the overflow condition, thereby reducing the water flow congestion in the detergent box 30 and serving as a safety protection function.

[0100] Exemplarily, referring to FIG. 1, the laundry treating apparatus further comprises a water outlet pipeline 70, the outer tub 11 has a water inlet, and the water outlet pipeline 70 connects the second drain 30a and the water inlet, the second drain 30a guides the overflowed detergent mixed solution into the drum assembly 10 through the water outlet pipeline 70, and plays a role of auxiliary water inlet.

[0101] In some embodiments, referring to FIG. 2, the laundry treating apparatus comprises a water inlet valve 90, the water inlet valve 90 has a first outlet 90a, and the first water path 40A and the second water path 50A are both communicated with the first outlet 90a. The water source supplies water to the laundry treating apparatus through the water inlet valve 90, and the first water path 40A and the second water path 50A are both connected to the first outlet 90a of the water inlet valve 90, so that the installation of the first water path 40A and the second water path 50A can be facilitated, the arrangement of the water inlet valve 90 can be simplified, and cost can be saved.

[0102] 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.
