[0042] The present application embodiment provides a detergent dispensing device 100, see Figure 2 The detergent dispensing device 100 comprises a liquid outlet water channel 20, a first water channel 40A, a second water channel 50A, and a turbulent flow structure 21. The first water channel 40A and the second water channel 50A are used to transport fluid.

[0043] An embodiment of the present application also provides a clothing processing device, and the type of the clothing processing device is not limited, for example, it can be a washing machine, a washer-dryer, etc.

[0044] See also Figure 1 and Figure 2 The laundry processing device comprises a laundry processing chamber and a detergent dispensing device 100 in any embodiment of the present application. The water outlet end of the liquid outlet waterway 20 of the detergent dispensing device 100 is connected to the laundry processing chamber.

[0045] The liquid outlet waterway 20 has a water inlet end and a water outlet end. Figures 2 to 8 In the drawings of this specification, the dashed lines with arrows indicate the direction of liquid flow.

[0046] The first water channel 40A is connected to the water source and the water inlet end of the liquid outlet water channel 20 , and the second water channel 50A is connected to the water source and the water inlet end of the liquid outlet water channel 20 .

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

[0048] It should be noted that the water source is a water source that supplies fluid to the first water channel 40A and the second water channel 50A, such as tap water; it can also be an internal water source of the clothing processing device, such as circulating water. Figure 2 The laundry processing device includes a water inlet valve 90, which is connected to a water source. The first water path 40A and the second water path 50A can be connected to different water inlet valves 90, or to the same water inlet valve 90, which is not limited here. As an optional embodiment, the laundry processing device includes a circulation 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 circulation pump of the laundry processing device.

[0049] It should be noted that the detergent mixed solution mentioned in this specification is only for the convenience of description, referring to a solution in which detergent is dissolved, and its mass percentage concentration is not limited. Of course, the detergent mixed solution is not limited to the detergent being completely dissolved. The fluid in the second water channel 50A is also not limited, and can be clean water, a detergent mixed solution, or a solution with other care ingredients added.

[0050] The detergent may be in any form, and may be powdered laundry detergent, flowable laundry liquid, flowable fabric softener, etc.

[0051] Exemplarily, the detergent dispensing device 100 includes a detergent supply assembly, the detergent supply assembly has a first drain port for discharging a detergent mixed solution, and the first water channel 40A communicates with a water source, the first drain port, and a water inlet end of the liquid outlet water channel 20. The detergent supply assembly includes a detergent box 30, and the first drain port can be formed by the detergent box 30 itself, or can be formed by the water outlet end of a water channel structure additionally provided at the top, side, or bottom of the detergent box 30.

[0052] For example, see Figure 2 The detergent dispensing device includes a detergent box 30 and a dispenser box (not shown) disposed in the detergent box, and the dispenser box is disposed in the detergent box 30. The dispenser box is formed with a detergent dispensing cavity, and the detergent box 30 has a first drain port. The first water path 40A flows through the detergent dispensing cavity and the first drain port. The fluid introduced into the water source by the first water path 40A enters the detergent dispensing cavity, mixes with the detergent, forms a detergent mixed solution, and is discharged from the detergent box 30 through the first drain port.

[0053] In some embodiments, the dispenser box is disposed in the detergent box 30 in a drawable manner. For example, the dispenser box can be at least partially drawn out of the detergent box 30 to the outside of the detergent box 30 along a horizontal direction.

[0054] It can be understood that after the first water channel 40A flows through the first drain outlet, it continues to flow with the detergent mixed solution and enters the liquid outlet water channel 20, and the second water channel 50A enters the liquid outlet water channel 20. The first water channel 40A and the second water channel 50A converge in the liquid outlet water channel 20, so that the two fluids are mixed. After mixing, they are discharged from the water outlet end of the liquid outlet water channel 20 and enter the clothing processing chamber.

[0055] The second water channel 50A is directly connected to the water source, and the detergent carried by the first water channel 40A can be further diluted and dissolved by the fluid in the second water channel 50A in the liquid outlet water channel 20. In this way, before the detergent enters the clothing processing chamber, the dissolution of the detergent can be further promoted, and the mixing uniformity of the detergent and water can be improved, thereby improving the utilization efficiency of the detergent and improving the cleaning ratio.

[0056] 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 a pipeline structure. The second waterway 50A refers to the flow path of the fluid, and does not specifically refer to a pipeline structure.

[0057] It should be noted that the water inlet end of the liquid outlet waterway 20 refers to the part where the fluid in the first waterway 40A leaves the first waterway 40A and enters the liquid outlet waterway 20, and the part 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 the part where the fluid in the liquid outlet waterway 20 leaves the liquid outlet waterway 20.

[0058] For example, in some embodiments, see Figure 6 The liquid outlet waterway 20 includes a mixing space 20a, and two ports 20b are arranged on the wall of the mixing space 20a. The fluid in the first waterway 40A enters the mixing space 20a from one of the 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 the water inlet ends of the liquid outlet waterway 20. The outlet end of the liquid outlet waterway 20 is arranged on the wall of the mixing space 20a.

[0059] In some other embodiments, please refer to Figure 7 The liquid outlet waterway 20 includes a mixing space 20a, and a port 20b is provided on the wall of the mixing space 20a. The fluid in the first waterway 40A enters the mixing space 20a from the port 20b. The water outlet end of the second waterway 50A extends into a certain position in the mixing space 20a. Then, the port 20b of the mixing space 20a can be considered as the water outlet end of the first waterway 40A, and also 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 of the liquid outlet waterway is provided on the wall of the mixing space 20a.

[0060] In some other embodiments, please refer to Figure 8 The clothing treatment device 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, and the mixing space 20a of the liquid outlet waterway is formed by a portion of the first tubular structure 1001, that is, 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 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 inner space of the mixing space 20a formed by the first tubular structure 1001, and the fluid in the second waterway 50A flows out from the water outlet end of the second tubular structure 1002 and merges with the fluid of the first waterway 40A in the mixing space 20a formed by the first tubular structure 1001. The water outlet section 1003 upstream of the mixing space 20a formed by the adjacent first tubular structure 1001 can be considered as the water outlet end of the first water channel 40A, and is also a water inlet end of the liquid outlet water channel 20. The water outlet end of the second tubular structure 1002 can be considered as the other water inlet end of the liquid outlet water channel 20. The water outlet end of the liquid outlet water channel is arranged on the first tubular structure 1001.

[0061] See also Figure 4 The detergent dispensing device 100 further includes a turbulent structure 21, which is disposed in the first water channel 40A or the second water channel 50A, and is used to provide a circumferential velocity component to the fluid in the second water channel 50A. That is, the turbulent structure 21 can be disposed in either the first water channel 40A or the second water channel 50A. The following description assumes that the turbulent structure 21 is disposed in the second water channel 50A.

[0062] The above-mentioned circumferential velocity component means that the velocity component of the fluid in the second water channel 50A after passing through the turbulent structure 21 is not zero in the circumferential direction of the second water channel 50A, and the circumferential direction of the second water channel 50A is perpendicular to the extension direction of the second water channel 50A.

[0063] After the fluid passes through the turbulent structure 21, the state of the fluid changes, and it tends to spread out in the circumferential direction, forming multiple fluids flowing in different directions, so that the fluids enter the liquid outlet waterway 20 and are better mixed with the fluid in the liquid outlet waterway 20, thereby improving the mixing efficiency. The fluid sprayed from the outlet end of the liquid outlet waterway 20 can also be dispersed in a roughly cone shape, with a wider radiation range and better visual effects.

[0064] It is understandable that the turbulent structure 21 can also increase the flow rate of the fluid by limiting the flow area of ​​the second water channel 50A where it is located. In this way, the speed difference between the two fluids entering the liquid outlet water channel 20 is larger, further promoting the dissolution of the detergent.

[0065] Exemplarily, the turbulent structure 21 includes one or more spiral blades, which are used to guide the spiral motion of the fluid. The spiral blade refers to a blade with a spiral shape, and the blade extends in a spiral direction. After the fluid passes through the spiral blade, it exhibits a spiral motion with a circumferential velocity component. The spiral blade has a simple structure, a good turbulent effect on the fluid, and a small resistance, thereby reducing the energy loss of the fluid when passing through.

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

[0067] In some embodiments, the outlet 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 end of the reduced diameter section 22 directly forms the outlet of the first water channel 40A or the second water channel 50A, or, in another embodiment, the end of the reduced diameter section 22 is connected to a constant diameter section and / or an expanded diameter section, and the constant diameter section and / or the expanded diameter section forms the outlet of the first water channel 40A or the second water channel 50A.

[0068] It should be noted that, along the moving direction of the fluid, the flow area of ​​the fluid in the above-mentioned reduced diameter section becomes smaller, the flow area in the above-mentioned equal diameter section remains basically unchanged, and the flow area in the above-mentioned expanded diameter section becomes larger.

[0069] The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area when the fluid is ejected. For example, the second waterway 50A is provided with the reduced diameter section 22. When the fluid in the second waterway 50A is ejected from the reduced diameter section 22, a greater impact force is generated on the fluid at the outlet end of the first waterway 40A, thereby achieving a better 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 larger injection speed, which can generate obvious 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 in under the action of the negative pressure and mixed with the fluid in the second water channel 50A, thereby improving the mixing and foaming effects.

[0071] In some embodiments, the extension lengths of the equal diameter section and the expanded diameter section along the second waterway 50A are both less than or equal to the extension length of the reduced diameter section 22 along the second waterway 50A. Since the longer the flow path of the fluid is, the more obvious its energy loss is, limiting the length of the equal diameter section and / or the expanded diameter section can reduce the loss of the circumferential velocity component and the loss of the impact force of the fluid after it flows out of the reduced diameter section 22.

[0072] In some embodiments, the second water channel 50A is provided with a turbulent structure 21 and a diameter-reducing section 22, and the diameter-reducing section 22 is located downstream of the turbulent structure 21. After the fluid passes through the turbulent structure 21 and the diameter-reducing section 22 in sequence, the fluid having a conical shape is ejected into the laundry processing chamber.

[0073] In this embodiment, the fluid in the first water channel 40A is a mixed solution of laundry detergent or a mixed solution of washing powder, especially a mixed solution of washing powder. Since washing powder is a powdered detergent, it is easier to clog and remain than laundry detergent, which may reduce the reliability of the first water channel 40A. If the turbulent structure 21 and the reduced diameter section 22 are set in the first water channel 40A, the above problems will be 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 the water source. The turbulent structure 21 and the reduced diameter section 22 are set in the second water channel 50A. The water flows through the second water channel 50A and is put into the water outlet to flow out at a high speed, impacting the mixed solution of washing powder at the water outlet of the first water channel 40A, fully mixing and generating a large amount of foam, and finally spraying a fluid with a large amount of foam in a roughly cone shape from the water outlet of the liquid outlet water channel 20.

[0074] For some examples, see Figure 2 The detergent dispensing device 100 includes a first pipeline 41 and a second pipeline 42. One end of the first pipeline 41 is introduced into a water source, for example, connected to 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 introducing the fluid into the detergent box 30. One end of the second pipeline 42 is connected to the first drain port, and the other end is connected to the liquid outlet waterway 20, for guiding the fluid discharged from the first drain port to the liquid outlet waterway 20. In this embodiment, the space in the first pipeline 41, the space in the second pipeline 42, and part of the space in the detergent box 30 together constitute at least a part of the first waterway 40A.

[0075] For some examples, see Figure 2 The detergent dispensing device 100 includes a third pipe 50, one end of which is connected to a water source and the other end is connected to the liquid outlet waterway 20. The space within the third pipe 50 can independently define a second waterway 50A, or the space within the third pipe 50 defines a portion of the second waterway 50A.

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

[0077] The second pipeline 42 may be a complete pipe or may be formed by connecting multiple pipe sections, which is not limited here.

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

[0079] For example, Figure 2 As shown, the third pipeline 50 can be entirely 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 that runs through the detergent box 30.

[0080] For some examples, see Figure 3 The first drain port 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 merges 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 port and the water inlet end of the liquid outlet waterway 20, the fluid passing through the first drain port is accelerated under the action of gravity and mixed 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, and no additional electric devices such as water pumps are required. Non-powered mixing can be achieved, which can save costs, simplify the structure, and enhance working stability.

[0082] It should be noted that the liquid outlet waterway 20 can be arranged directly below the first drain outlet, or can be arranged obliquely below the first drain outlet, as long as there is a height difference between the water inlet end of the liquid outlet waterway 20 and the first drain outlet along the gravity direction G.

[0083] For some examples, see Figure 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 acceleration effect of gravity is more obvious when it is discharged through the first drain port.

[0084] In some embodiments, any position of the first water channel 40A is not lower than the water inlet end of the liquid outlet water channel 20 in the gravity direction G. That is, the junction between the liquid outlet water channel 20 and the first water channel 40A is located at the lowest point of the first water channel 40A, so that the energy loss of the detergent mixed solution in the first water channel 40A is less when it converges in the liquid outlet water channel 20.

[0085] In some embodiments, any position of the second water channel 50A is not lower than the water inlet end of the liquid outlet water channel 20 in the gravity direction G. That is, the junction between the liquid outlet water channel 20 and the second water channel 50A is located at the lowest point of the second water channel 50A, so that when the fluid in the second water channel 50A converges at the liquid outlet water channel 20, its energy loss is less.

[0086] Exemplarily, the flow rate at the end of the first water channel 40A is less than the flow rate at the end of the second water channel 50A. The end of the first water channel 40A refers to the part where the fluid in the first water channel 40A leaves the first water channel 40A, which can also be understood as the junction of the first water channel 40A and the liquid outlet water channel 20. The end of the second water channel 50A refers to the part where the fluid in the second water channel 50A leaves the second water channel 50A, which can also be understood as the junction of the second water channel 50A and the liquid outlet water channel 20.

[0087] The fluid with a relatively slow flow rate from the first water channel 40A in the liquid outlet water channel 20 is mixed with the fluid with a relatively fast flow rate from the second water channel 50A, which can further promote the dissolution of the detergent.

[0088] For some examples, see Figure 1 The clothing treatment device includes a barrel assembly 10, and the barrel assembly 10 includes an inner barrel (not shown). Exemplarily, the barrel assembly 10 also includes an outer barrel 11, and the inner barrel is rotatably arranged in the outer barrel 11. The outer barrel 11 is used to hold water for washing clothes, and the inner barrel is used to hold clothes. In this embodiment, the inner barrel holds water through the outer barrel 11, and the inner barrel can also be called a perforated inner barrel. In other embodiments, the inner barrel holds water by itself, and can also be called a non-porous inner barrel. The outer barrel 11 can be set outside the inner barrel, or the outer barrel 11 can be not set.

[0089] It is understandable that in some embodiments, the barrel assembly 10 may only have an inner barrel without the outer barrel 11. In this embodiment, the inner barrel is a hole-free inner barrel that can hold water by itself.

[0090] For example, see Figure 1The clothing treatment device further includes a door body (not shown), a box body (not shown), and a door seal 60 disposed on the front side of the barrel assembly 10. The barrel assembly 10 is disposed in the box body. The box body is provided with an opening communicating with the inside of the barrel assembly 10, and the door body is used to open or close the opening. The door seal 60 is used to seal the gap between the barrel assembly 10 and the opening of the box body. When the door body closes the opening, the door body seals against the door seal 60, thereby, the communicating space formed by the door body, the door seal 60 and the inside of the barrel assembly 10 constitutes a clothing treatment chamber.

[0091] The door sealing ring 60 has an installation opening, and the water outlet end of the liquid outlet waterway 20 passes through the installation opening of the door sealing ring 60 and extends to the radial inner side of the door sealing ring 60. In this way, the water outlet end of the liquid outlet waterway 20 is conducive to directly delivering the mixed liquid of the first waterway 40A and the second waterway 50A directly into the clothing processing chamber.

[0092] The above-mentioned direct delivery to the clothes processing chamber means that the mixed liquid discharged from the first water channel 40A and the second water channel 50A by the liquid outlet water channel 20 is directly delivered to the clothes processing chamber under the action of the gravity and pressure of the fluid itself without being guided by other structures. In this way, the mixed liquid is sprayed to wet the clothes, which can improve their cleaning effect.

[0093] In some embodiments, the water outlet end of the liquid outlet water channel 20 is inclined to discharge water toward the lower rear of the clothing processing chamber, so that the sprayed water can cover the clothes in the clothing processing chamber over a large area.

[0094] For example, in one embodiment, the detergent box 30 further has a mixing chamber, which is used to receive the fluid flowing through the detergent delivery chamber, and the first drain port is arranged on the wall of the mixing chamber, that is, the mixed liquid mixed with detergent enters the mixing chamber and is discharged from the first drain port.

[0095] Exemplarily, the mixing chamber is located below the dispenser box, and the detergent mixed solution flows from the detergent delivery chamber of the dispenser box to the mixing chamber below the dispenser box, and is discharged from the first drain port.

[0096] For some examples, see Figure 3 The detergent box also has an overflow chamber and a second drain port 30a. The overflow chamber is used to receive the detergent mixed solution overflowing from the mixing chamber. The second drain port 30a is used to discharge the detergent mixed solution in the overflow chamber out of the detergent box 30.

[0097] In this embodiment, when the water level in the mixing chamber is not higher than the overflow water level, the fluid in the mixing chamber is discharged from the first drain port 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 port 30a, that is, the detergent box preferentially discharges water from the first drain port, and the second drain port 30a plays a safety protection role, and can timely discharge the excess water in the mixing chamber.

[0098] Exemplarily, the fluid cross-sectional area of ​​the second drain port 30a is greater than that of the first drain port, that is, when the amount of water is equally sufficient, the drainage volume of the second drain port 30a is greater than that of the first drain port.

[0099] Since the fluid cross-sectional area of ​​the first drain port is small, the water flow rate of the first drain port is relatively small. The second drain port 30a and the overflow cavity can timely discharge the fluid in the first water path 40A in the event of overflow, thereby alleviating water congestion in the detergent box 30 and playing a role in safety protection.

[0100] For example, see Figure 1 The clothing processing device also includes a water outlet pipe 70. The outer barrel 11 has a water inlet. The water outlet pipe 70 connects the second drain port 30a and the water inlet. The second drain port 30a introduces the overflowed detergent mixed solution into the drum assembly 10 through the water outlet pipe 70, which plays a role in assisting water inlet.

[0101] For some examples, see Figure 2 The laundry processing device includes a water inlet valve 90, and the water inlet valve 90 has a first outlet 90a, and the first water path 40A and the second water path 50A are both connected to the first outlet 90a. The water source supplies water to the laundry processing device 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, and the setting of the water inlet valve 90 can be simplified, saving costs.

[0102] like Figure 2 As shown, the water inlet valve 90 also has a second outlet 90b, which can be used to supply water to other pipelines.
