[0058] In this embodiment, the outer tub holds water, and the inner tub can also be called a perforated inner tub. The space within the inner tub forms part of the laundry processing chamber. Fluid can flow between the space between the outer tub and the inner tub and the space within the inner tub through the flow holes in the inner tub.

[0059] In some embodiments, the outer barrel may be substantially in the shape of a hollow cylinder.

[0060] It should be noted that, for ease of understanding, the Figure 4 and Figure 16 , the first water channel 40A, the second water channel 50A and the overflow water channel 180A of the present application are schematically shown in the form of dotted arrows.

[0061] The dispensing assembly provided in the embodiment of the present application includes a first water channel 40A, a second water channel 50A, and an overflow water channel 180A. At least one of the first water channel 40A and the second water channel 50A is used to transport the detergent mixed solution. The overflow water channel 180A is used to receive the fluid overflowing from the first water channel 40A.

[0062] See also Figure 4 、 Figure 8 、 Figure 11 and Figure 16 An embodiment of the present application provides a nozzle assembly, at least part of which is formed on a workbench 80. The nozzle assembly includes a liquid outlet channel 130b and a liquid flow channel 130a. The water outlet end 50Aa of the liquid flow channel 130a is inserted into the liquid outlet channel 130b. The pipe section of the liquid flow channel 130a located inside the liquid outlet channel 130b is provided with a turbulent structure 21. The turbulent structure 21 is used to provide a circumferential velocity component to the fluid in the liquid flow channel 130a. At least one of the liquid flow channel 130a and the liquid outlet channel 130b transports a mixed detergent solution.

[0063] For example, the liquid flow channel 130a conveys a detergent mixed solution, and the liquid outlet channel 130b conveys other fluids. For another example, the liquid outlet channel 130b conveys a detergent mixed solution, and the liquid flow channel 130a conveys other fluids. For another example, both the liquid flow channel 130a and the liquid outlet channel 130b convey a detergent mixed solution.

[0064] Other fluids include but are not limited to water or solutions with other care ingredients added, etc. Water includes but is not limited to tap water or recycled water from a water source.

[0065] At least a portion of the nozzle assembly is formed on the workbench 80, which means that at least a portion of the nozzle assembly is formed from the physical structure of the workbench 80. Exemplarily, at least a portion of the nozzle assembly is integrally formed with at least a portion of the physical structure of the workbench 80. For example, at least a portion of the nozzle assembly is integrally injection molded with at least a portion of the physical structure of the workbench 80, etc.

[0066] The water outlet end 50Aa of the liquid flow channel 130a is inserted into the liquid outlet channel 130b, and the fluid in the liquid flow channel 130a enters the liquid outlet channel 130b and mixes with the fluid in the liquid outlet channel 130b.

[0067] The above-mentioned circumferential velocity component means that the velocity component of the fluid in the liquid flow channel 130a after passing through the turbulent structure 21 in the circumferential direction of the liquid flow channel 130a is not zero, and the circumference of the liquid flow channel 130a surrounds the extension direction of the liquid flow channel 130a.

[0068] The nozzle combination provided in the embodiment of the present application is formed at least partially on the workbench 80, and part of the structure of the workbench 80 is reused as at least part of the nozzle combination, which can reduce the number of parts, simplify the structure, and save costs. The water outlet end 50Aa of the liquid flow channel 130a is inserted into the liquid outlet channel 130b, and the fluid in the liquid flow channel 130a enters the liquid outlet channel 130b. The fluid in the liquid flow channel 130a and the fluid in the liquid outlet channel 130b converge and mix, which can further promote the dissolution of the detergent, enhance the mixing effect, improve the utilization rate of the detergent, and improve the cleaning effect. After passing through the turbulent structure 21, the fluid in the liquid flow channel 130a generates a composite motion in multiple directions such as the circumferential direction and the forward direction, so as to better mix with the fluid from the liquid outlet channel 130b and improve the mixing efficiency. The turbulent structure 21 can also make the fluid disperse roughly in a cone shape, with a wider radiation range and better visual effect.

[0069] See also Figure 4 、 Figure 8 、 Figure 11 and Figure 16 The present invention provides a delivery assembly comprising a first waterway 40A, a second waterway 50A, and a nozzle assembly according to any one of the embodiments of the present invention. The liquid outlet channel 130b is part of the first waterway 40A. The liquid flow channel 130a is part of the second waterway 50A.

[0070] The dispensing component provided in the embodiment of the present application, at least one of the first water channel 40A and the second water channel 50A is used to transport the detergent mixed solution, the water outlet end 50Aa of the liquid flow channel 130a is inserted into the liquid outlet channel 130b, the fluid in the liquid flow channel 130a enters the liquid outlet channel 130b, the fluid in the liquid flow channel 130a and the fluid in the liquid outlet channel 130b converge and mix, which can further promote the dissolution of the detergent, enhance the mixing effect, increase the utilization rate of the detergent, and improve the cleaning effect.

[0071] One of the first water channel 40A and the second water channel 50A is used to transport the detergent mixed solution, and the other of the first water channel 40A and the second water channel 50A is used to transport water.

[0072] For example, the first water channel 40A is used to transport the detergent mixed solution, and the second water channel 50A is used to transport water. For another example, the second water channel 50A is used to transport the detergent mixed solution, and the first water channel 40A is used to transport water.

[0073] An embodiment of the present application provides a clothing processing device, which includes a clothing processing chamber, a workbench 80 and a dispensing assembly according to any one of the embodiments of the present application, and the fluid in the liquid outlet channel 130b enters the clothing processing chamber.

[0074] In the clothing processing device provided in the embodiment of the present application, the fluid in the second water channel 50A enters the liquid outlet channel 130b, and the fluid in the liquid outlet channel 130b enters the clothing processing chamber. That is, the fluid in the first water channel 40A and the fluid in the second water channel 50A both enter the clothing processing chamber and participate in clothing processing.

[0075] For the convenience of description, the following explanation will be given by taking the first water channel 40A transporting a detergent mixed solution and the second water channel 50A transporting liquid water as an example. It can be understood that the first water channel 40A transporting liquid water and the second water channel 50A transporting a detergent mixed solution can also have the same or corresponding effects, which will not be repeated in this application.

[0076] In some embodiments, at least a portion of the sidewall of the liquid outlet channel 130b is formed on the workbench 80. The water outlet end 50Aa of the liquid flow channel 130a may be the water outlet end of the second water channel 50A.

[0077] At least a portion of the sidewall of the liquid outlet channel 130 b is formed on the workbench 80 , which means that at least a portion of the sidewall of the liquid outlet channel 130 b is formed by the physical structure of the workbench 80 .

[0078] The water outlet end of the second water channel 50A is inserted into the liquid outlet channel 130 b , and the fluid transported by the second water channel 50A enters the liquid outlet channel 130 b .

[0079] In this embodiment, at least a portion of the sidewall of liquid outlet channel 130b is formed on the workbench 80, which reduces the number of pipes installed on the workbench 80, simplifies the pipe layout, and reduces manufacturing difficulties. Furthermore, the outlet end of the second water channel 50A is inserted into the liquid outlet channel 130b, allowing the fluid in the second water channel 50A to enter the liquid outlet channel 130b. The fluid in the second water channel 50A and the fluid in the liquid outlet channel 130b converge and mix, further promoting detergent dissolution, enhancing mixing efficiency, increasing detergent utilization, and improving cleaning results.

[0080] It should be noted that the detergent mixed solution mentioned in this application is merely for convenience of description and refers to a mixed solution in which detergent is dissolved. The mass percentage concentration is not limited, and the detergent mixed solution is not limited to a solution in which the detergent is completely dissolved. In some embodiments, the detergent mixed solution can be a user-added detergent stock solution. In other embodiments, the detergent mixed solution can be a mixture of detergent and a fluid from a water source.

[0081] The functions of detergents are not limited. For example, the functions of detergents include but are not limited to cleaning, softening or adding fragrance.

[0082] The type of detergent is not limited, and the detergent includes but is not limited to detergent, softener and / or fragrance, etc.

[0083] The form of the detergent is not limited, and it can be powdered laundry detergent or flowable laundry liquid.

[0084] It is understandable that the detergent mixed solution and water are both fluids. The first water channel 40A and the second water channel 50A are both used to transport fluids.

[0085] In one embodiment, please refer to Figure 4 、 Figure 8 、 Figure 11 and Figure 16 The nozzle assembly includes a nozzle 130 having a liquid outlet channel 130b and a cannula 131 having a liquid flow channel 130a. At least a portion of the nozzle 130 is formed on the workbench 80, and at least a portion of the cannula 131 is inserted into the liquid outlet channel 130b.

[0086] At least a portion of the nozzle 130 is formed on the workbench 80, which means that a portion of the physical structure of the workbench 80 constitutes at least a portion of the physical structure of the nozzle 130. In other words, at least a portion of the nozzle 130 and the workbench 80 may be an integrally formed structure, for example, at least a portion of the nozzle 130 and the workbench 80 may be integrally injection molded.

[0087] The cannula 131 can be a separately manufactured component. That is, the cannula 131 and the workbench 80 are manufactured separately. The cannula 131 can be fixed to the workbench 80 by a detachable connection or a non-detachable connection.

[0088] At least a portion of the cannula 131 is inserted into the liquid outlet channel 130b. This can be done by partially inserting the cannula 131 into the liquid outlet channel 130b, or by fully inserting the cannula 131 into the liquid outlet channel 130b. Partial insertion of the cannula 131 into the liquid outlet channel 130b facilitates connection of the portion of the cannula 131 outside the liquid outlet channel 130b to other pipes, valves, and the like.

[0089] At least a portion of the insertion tube 131 into the liquid outlet channel 130b may be formed by the insertion tube 131 and the liquid outlet channel 130b being sleeved together. The connection between the two is simple and easy to operate, which can reduce the difficulty of assembly.

[0090] In this embodiment, at least a portion of the nozzle 130 is formed on the workbench 80. Part of the structure of the workbench 80 is reused as at least a portion of the nozzle 130, which reduces the number of parts, simplifies the structure, and saves costs. The space within the cannula 131 is used to form the liquid flow channel 130a, which is simple in structure and easy to manufacture. Inserting at least a portion of the cannula 131 into the liquid outlet channel 130b facilitates the entry of liquid in the cannula 131 into the liquid outlet channel 130b, thereby impacting the detergent mixed solution in the first water channel 40A and further diluting the detergent.

[0091] For some examples, see Figures 12 to 16 The workbench 80 is partially recessed to form the liquid outlet channel 130b. For example, the workbench 80 is partially recessed to form the liquid outlet channel 130b. In other words, the workbench 80 can be completely utilized to form the liquid outlet channel 130b for fluid circulation without requiring components such as the partition 150. This saves components and reduces costs.

[0092] For some examples, see Figures 1 to 11 A partition 150 is provided on the underside of the workbench 80. Together, the partition 150 and the workbench 80 form a liquid outlet channel 130b. Specifically, the partition 150 and the workbench 80 enclose and form the liquid outlet channel 130b, with the partition 150 and the workbench 80 serving as side walls of the liquid outlet channel 130b. By jointly defining the liquid outlet channel 130b with the partition 150 and the workbench 80, the number of pipes installed on the workbench 80 can be reduced, simplifying the pipe layout and reducing manufacturing complexity.

[0093] The partition member 150 and the workbench 80 can be connected in a detachable or non-detachable manner. In some embodiments, the partition member 150 and the workbench 80 can be welded or bonded. In some embodiments, the partition member 150 and the workbench 80 can be connected by snapping, screwing, or bolting.

[0094] The connection between the partition member 150 and the workbench 80 can be sealed. In this way, fluid leakage at the connection between the partition member 150 and the workbench 80 is avoided.

[0095] For example, the connection between the partition member 150 and the workbench 80 can be sealed by welding, gluing, or by a sealant. The sealant can be a flexible structure that utilizes elastic deformation to seal the gap between the partition member 150 and the workbench 80. For example, the sealant can be a flexible structure made of rubber and / or silicone.

[0096] For some examples, see Figures 1 to 16 The dispensing assembly includes a detergent box 30 and a dispenser box 140 that is movably arranged in the detergent box 30. The dispenser box 140 forms a detergent dispensing chamber 140a, and the detergent box 30 forms a mixing chamber 30d. The detergent dispensing chamber 140a and the mixing chamber 30d are both part of the first water channel 40A. The mixing chamber 30d connects the detergent dispensing chamber 140a and the liquid outlet channel 130b.

[0097] The detergent delivery chamber 140a is used to hold detergent. The detergent delivery chamber 140a can be suitable for accommodating powdered laundry detergent. Of course, the detergent delivery chamber 140a can also be suitable for accommodating detergent with flow characteristics, such as laundry liquid.

[0098] The detergent dispensing chamber 140a has a discharge port 140b, which communicates with the mixing chamber 30d. The discharge port 140b is used to discharge fluid, such as detergent, from the detergent dispensing chamber 140a. The discharge port 140b connects the detergent dispensing chamber 140a with the mixing chamber 30d. The mixing chamber 30d is located downstream of the detergent dispensing chamber 140a. The detergent in the detergent dispensing chamber 140a flows through the discharge port 140b into the mixing chamber 30d. The mixing chamber 30d is used to hold a mixed detergent solution.

[0099] In this embodiment, the first water channel 40A is used to transport the detergent mixed solution. The detergent in the detergent dispensing chamber 140a enters the mixing chamber 30d for further mixing. The mixing chamber 30d provides space for further dissolution of the detergent, thereby improving the uniformity of the detergent mixed solution. The dispenser box 140 is removably disposed within the detergent box 30, meaning that the dispenser box 140 can be inserted into or removed from the detergent box 30. In this manner, the dispenser box 140 can move relative to the detergent box 30 to facilitate dispensing detergent into the detergent dispensing chamber 140a.

[0100] For some examples, see Figures 1 to 16 , at least a portion of the detergent box 30 is formed on the workbench 80 .

[0101] At least part of the detergent box 30 is formed on the workbench 80, which means that part of the physical structure of the workbench 80 constitutes at least part of the physical structure of the detergent box 30. For example, at least part of the detergent box 30 can be integrally formed with the workbench 80.

[0102] In this embodiment, at least a portion of the detergent box 30 is formed on the workbench 80, and part of the structure of the workbench 80 is reused as at least a portion of the detergent box 30, which can reduce the number of parts, simplify the structure, and save costs.

[0103] It should be noted that the detergent box 30 in the present application can also be referred to as a nozzle body.

[0104] In one embodiment, please refer to Figures 8 to 16 The section of the liquid flow channel 130a located inside the liquid outlet channel 130b is provided with a pressurizing structure 120, and the pressurizing structure 120 is used to increase the flow rate of the fluid in the liquid flow channel 130a.

[0105] In this embodiment, the flow rate or shape of the fluid in the liquid flow channel 130a is changed by the pressurizing structure 120 to better impact the detergent mixed solution in the liquid outlet channel 130b, thereby accelerating the dissolution of the detergent and improving uniformity.

[0106] In some embodiments, the flow rate of the water outlet end of the second water channel 50A is greater than the flow rate of the water outlet end of the first water channel 40A. Exemplarily, the flow rate of the water outlet end 50Aa of the liquid flow channel 130a is greater than the flow rate of the water outlet end 40Aa of the liquid outlet channel 130b. On the one hand, there is a flow rate difference between the fluid discharged from the liquid flow channel 130a and the fluid discharged from the liquid outlet channel 130b. The flow rate of the water outlet end 50Aa of the liquid flow channel 130a is relatively large, which can increase the impact force of the fluid. The flow rates of the two fluids entering the mixing space 20a are one fast and the other slow. The one with a faster flow rate can impact and disturb the one with a slower flow rate, so that the detergent can be better mixed when the two fluids meet, further promoting the dissolution of the detergent. On the other hand, the flow rate at the outlet end 50Aa of the liquid flow channel 130a is relatively high, which can generate negative pressure in the surrounding area, so that the fluid at the outlet end 40Aa of the liquid outlet channel 130b is sucked under the action of the negative pressure, thereby improving the mixing effect.

[0107] See also Figures 1 to 16 The dispensing component includes an overflow water channel 180A, which is used to receive the detergent mixed solution overflowing from the first water channel 40A.

[0108] The overflow water channel 180A is used to receive the detergent mixed solution overflowing from the first water channel 40A, which means that: when the liquid level of the detergent mixed solution in the first water channel 40A is not higher than the overflow liquid level, the detergent mixed solution is basically transported to the clothing processing chamber through the first water channel 40A; when the liquid level of the detergent mixed solution in the first water channel 40A is higher than the overflow liquid level, the excess detergent mixed solution in the first water channel 40A overflows into the overflow water channel 180A and enters the clothing processing chamber through the overflow water channel 180A.

[0109] It is understandable that the overflow liquid level can be set according to demand and is not limited in this application.

[0110] In this embodiment, when the level of the detergent mixed solution in first water channel 40A exceeds the overflow level, the excess detergent mixed solution in first water channel 40A overflows into overflow water channel 180A and enters the clothing treatment chamber through overflow water channel 180A. Overflow water channel 180A serves as a safety protection, allowing for the timely discharge of excess detergent mixed solution in first water channel 40A. Compared to the related art solution that uses only one water outlet for dispensing detergent, the present application uses both first water channel 40A and overflow water channel 180A for dispensing the detergent mixed solution into the clothing treatment chamber, enriching the dispensing paths for the detergent mixed solution.

[0111] In some embodiments, an addition port communicating with the detergent delivery chamber 140a is formed on the upper surface of the dispenser box 140. A user can add detergent to the detergent delivery chamber 140a through the addition port from above.

[0112] In some embodiments, the detergent delivery chamber 140a can be flushed with water so that the detergent in the detergent delivery chamber 140a enters the mixing chamber 30d. For example, the water spray port can spray water into the detergent delivery chamber 140a, and the water flow impacts the detergent in the delivery chamber to produce a detergent mixed solution, which then enters the mixing chamber 30d through the discharge port 140b.

[0113] In some embodiments, a water spray port may be formed on the workbench 80 .

[0114] In one embodiment, the water spray port may be located above the detergent delivery chamber 140a.

[0115] The number of detergent dispensing chambers 140a is not limited, and the number of detergent dispensing chambers 140a can be one or more. Taking multiple detergent dispensing chambers 140a as an example, the multiple detergent dispensing chambers 140a can be arranged in a direction perpendicular to the vertical direction. For example, the multiple detergent dispensing chambers 140a can be arranged in a left-right direction or a front-back direction. Each detergent dispensing chamber 140a can dispense detergents with different functions or the same function.

[0116] In some embodiments, the workbench 80 forms an open slot opening downward, and the partition member 150 closes the downward opening of the open slot to form the liquid outlet channel 130 b of the spray head 130 and the mixing chamber 30 d of the detergent box 30 .

[0117] In one embodiment, the dispenser box 140 can be pulled out of the detergent box 30. For example, at least a portion of the dispenser box 140 is pulled out to the outside of the detergent box 30, and the user can put the detergent into the detergent dispensing cavity 140a. When the dispensing is completed or the clothes need to be washed, the dispenser box 140 can be put into, for example, the detergent box 30.

[0118] In one embodiment, please refer to Figures 12 to 16 The dispensing assembly includes a water retaining rib 170 and a detergent box 30. The detergent box 30 has a cavity. At least a portion of the detergent box 30 is formed on the workbench 80. The water retaining rib 170 extends upward from the wall of the cavity to separate the cavity into a sub-cavity and an overflow cavity 30c. The sub-cavity is part of the first waterway 40A, and the overflow cavity 30c is part of the overflow waterway 180A.

[0119] In this embodiment, the vertical height of water retaining rib 170 is the height of the overflow liquid level. The upper surface of water retaining rib 170 is spaced from the surface of the cavity; that is, there is a gap between the upper surface of water retaining rib 170 and the surface of the cavity. The level of the detergent mixture in the sub-cavity is higher than the vertical height of water retaining rib 170. The detergent mixture in the sub-cavity flows over the upper surface of water retaining rib 170 and into the overflow cavity 30c through the gap between the upper surface of water retaining rib 170 and the surface of the cavity.

[0120] In one embodiment, please refer to Figure 11 and Figure 16 The nozzle assembly includes a mixing space 20a, and the water outlet end 40Aa of the liquid outlet channel 130b and the water outlet end 50Aa of the liquid flow channel 130a are both connected to the mixing space 20a.

[0121] In this embodiment, the fluid from the liquid flow channel 130a and the fluid from the liquid outlet channel 130b both enter the mixing space 20a to converge and mix, thereby improving the mixing effect and allowing the detergent, such as washing powder, to be more fully dissolved.

[0122] The outlet end 40Aa of the liquid outlet channel 130b is the location where the fluid in the liquid outlet channel 130b leaves the liquid outlet channel 130b. The outlet end 50Aa of the liquid flow channel 130a is the location where the fluid in the liquid flow channel 130a leaves the liquid flow channel 130a.

[0123] In one embodiment, please refer to Figures 1 to 16Spray head 130 defines a mixing space 20a and a liquid outlet 20ab communicating with mixing space 20a. Mixing space 20a is located between the outlet end of second water channel 50A and liquid outlet 20ab. Liquid outlet 20ab is used to discharge the fluid within mixing space 20a. Fluid from first water channel 40A and fluid from second water channel 50A converge and mix in mixing space 20a before being discharged through liquid outlet 20ab into the laundry processing chamber to participate in laundry processing.

[0124] In one embodiment, please refer to Figures 1 to 16 The liquid outlet 20ab is formed on the workbench 80, so that the fluid discharged from the liquid outlet 20ab is ejected downward into the laundry processing chamber under the action of gravity and initial velocity. At least part of the space between the water outlet end of the second water channel 50A and the liquid outlet 20ab is a mixing space 20a.

[0125] For example, in some embodiments, please refer to Figure 7 and Figure 11 The mixing space 20a can be the space defined by the line connecting the water outlet end of the second water channel 50A and the liquid outlet 20ab, see Figure 11 In the figure, the space defined by the dotted line between the outlet end of the second water channel 50A and the liquid outlet 20ab is the mixing space 20a. The outlet end of the second water channel 50A can be the boundary between the second water channel 50A and the mixing space 20a, that is, the outlet end of the first water channel 40A surrounds the outside of the mixing space 20a.

[0126] The liquid outlet 20ab is a through hole that penetrates the outer surface of the physical part. In some embodiments, please refer to Figure 3 and Figure 13 The liquid outlet 20ab is formed on the surface of the workbench 80 facing the clothing loading port 80a. In this way, it is possible to avoid as much as possible that the structure on the workbench 80 blocks the liquid outlet 20ab from discharging fluid.

[0127] In one embodiment, the liquid outlet 20ab is tilted toward the front and lower portion of the laundry processing chamber. That is, the axis of the liquid outlet 20ab is obliquely intersected with a straight line extending in the vertical direction, so that the detergent mixture sprayed from the liquid outlet 20ab can cover a large area of ​​the laundry in the laundry processing chamber.

[0128] In one embodiment, the outlet of the second water channel 50A is inserted into the first water channel 40A. For example, a hole is formed on the wall of the first water channel 40A, and the second water channel 50A is inserted into the hole and extends into the first water channel 40A. In this way, the fluid in the second water channel 50A and the fluid in the first water channel 40A can quickly come into contact and mix.

[0129] In some embodiments, the connection between the second water channel 50A and the first water channel 40A is sealed. Exemplarily, the connection between the second water channel 50A and the receptacle is sealed.

[0130] The sealing method of the connection between the second water channel 50A and the first water channel 40A is not limited. For example, the connection between the second water channel 50A and the first water channel 40A can be sealed by a sealing structure. For example, a sealing structure is provided between the outer peripheral surface of the second water channel 50A and the hole surface of the jack.

[0131] The sealing structure may be a flexible structure that utilizes elastic deformation of the sealing structure to seal the gap at the connection between the second water channel 50A and the first water channel 40A. For example, the sealing structure may be a flexible structure made of rubber and / or silicone.

[0132] In one embodiment, the outlet of the second water channel 50A is inserted into the first water channel 40A, and the mixing space 20a can be located within the first water channel 40A. The mixing space 20a is located downstream of the outlet of the second water channel 50A and is disposed within the first water channel 40A. The outlet of the second water channel 50A and the wall of the first water channel 40A define the mixing space 20a. Fluid from the second water channel 50A impacts the detergent mixture within the mixing space 20a, accelerating detergent dissolution and improving the uniformity of the detergent-water mixture, thereby increasing detergent utilization efficiency and improving the cleaning efficiency.

[0133] In one embodiment, please refer to Figure 3 The cannula 131 is inserted into the workbench 80. That is, the workbench 80 is formed with a socket, and the cannula 131 is inserted into the socket. In this design, the workbench 80 provides an installation position for the cannula 131, simplifies the installation operation process of the cannula 131, and improves production efficiency.

[0134] In one embodiment, the partition member 150 forms an insertion hole, and the insertion tube 131 is inserted into the insertion hole.

[0135] In some embodiments, the gap between the cannula 131 and the insertion hole can be sealed by a sealing structure. For example, the gap between the cannula 131 and the insertion hole can be sealed by a sealing ring.

[0136] In one embodiment, please refer to Figure 4 、 Figure 7 、 Figure 8 Hehe Figure 11The insert tube 131 includes a horizontal section 1311 and a curved section 1312 connected to the horizontal section 1311. The axis of the horizontal section 1311 extends horizontally, and the curved section 1312 bends downward from the horizontal section 1311. The outlet of the second water channel 50A is formed at the curved section 1312. For example, the end of the curved section 1312, which is away from the horizontal section 1311, serves as the outlet of the second water channel 50A. The horizontal section 1311 facilitates plugging into the socket. The curved section 1312 directs fluid downward, allowing the outlet of the second water channel 50A to spray downward, allowing the fluid to quickly contact the clothing below.

[0137] In one embodiment, the projection of the outlet end of the second water channel 50A is located within the projection of the outlet 20ab, using the plane on which the outlet 20ab lies as the projection plane. For example, the flow area of ​​the outlet 20ab can be larger than the flow area of ​​the outlet end of the second water channel 50A. This prevents the outlet end of the second water channel 50A from being misaligned with the outlet 20ab, thereby preventing changes in fluid flow direction.

[0138] It should be noted that the flow cross-section is a cross-section perpendicular to the streamline cluster. When the streamline clusters are non-parallel, the flow cross-section is a curved surface; when the streamline clusters are parallel straight lines, the flow cross-section is a flat surface. The flow area refers to the area of ​​the flow cross-section. For example, if the liquid outlet 20ab is circular, the flow area of ​​the liquid outlet 20ab can be the area of ​​the circle.

[0139] In one embodiment, please refer to Figures 1 to 11 Part of the partition member 150 and the workbench 80 define a portion of the detergent box 30, and another portion of the partition member 150 and the workbench 80 define the spray head 130. Exemplarily, with a plane perpendicular to the up-down direction as a projection plane, when the dispenser box 140 is stored in the detergent box 30, the projection of the dispenser box 140 at least partially overlaps with the projection of the detergent box 30, and the projection of the dispenser box 140 is spaced apart from the projection of the spray head 130.

[0140] In one embodiment, the detergent box 30 and the spray head 130 are both formed by the workbench 80. That is, the workbench 80 is not provided with the partition member 150, and the entire detergent box 30 and the entire spray head 130 are both formed by the workbench 80.

[0141] In one embodiment, please refer to Figures 12 to 16 A pumping port 80b is formed on the surface of the workbench 80 facing the clothing loading port 80a, and the pumping port 80b is connected to the cavity of the detergent box 30. The sub-cavity is located on the side of the water retaining rib 170 away from the pumping port 80b, and the overflow chamber 30c is located on the side of the water retaining rib 170 close to the pumping port 80b.

[0142] An overflow waterway 180A is formed between the overflow chamber 30c and the pumping port 80b. The detergent mixed solution overflowing from the sub-chamber passes over the water retaining rib 170 and enters the overflow chamber 30c, and then directly enters the laundry processing chamber through the pumping port 80b.

[0143] The detergent dispensing chamber 140a, its sub-chamber, and the liquid outlet channel 130b constitute the first water channel 40A. The sub-chamber includes a holding chamber 30e and a mixing chamber 30d. The holding chamber 30e is located above the mixing chamber 30d, and the upper sidewall of the mixing chamber 30d forms a filter hole 160a. The detergent mixed solution in the detergent dispensing chamber 140a enters the holding chamber 30e, then passes through the mixing chamber 30d and enters the liquid outlet channel 130b of the nozzle 130.

[0144] The filter holes 160a are used to limit the particle size of the circulating particles, thereby playing a filtering role.

[0145] The dispenser box 140 enters and exits the detergent box 30 through the pumping port 80b. To add detergent to the dispenser box 140, the dispenser box 140 can be pulled out of the detergent box 30 through the pumping port 80b. Once the detergent addition is complete, the dispenser box 140 can be pushed back into the detergent box 30 through the pumping port 80b. During the washing process, the detergent and other fluids in the detergent delivery chamber 140a can flow through the first waterway 40A, for example, sequentially through the accommodating chamber 30e, the mixing chamber 30d, the liquid outlet channel 130b, and the mixing space 20a, before being delivered to the laundry processing chamber from the liquid outlet 20ab. Alternatively, the detergent and other fluids in the accommodating chamber 30e can overflow into the overflow chamber 30c and enter the laundry processing chamber through the pumping port 80b.

[0146] In one embodiment, the insertion tube 131 is located on the left or right side of the detergent box 30. The insertion tube 131 and the detergent box 30 are arranged in the left-right direction, which can reduce the vertical dimensions occupied by the insertion tube 131 and the detergent box 30, thereby avoiding excessively increasing the overall vertical height of the workbench 80.

[0147] In some embodiments, the mixing space 20a can be located on one side of the dispenser box 140, and the detergent dispensing chamber 140a is connected to the mixing space 20a. The mixing space 20a and the dispenser box 140 are compactly arranged, and the detergent mixed solution from the detergent dispensing chamber 140a flows a certain distance and for a certain period of time before entering the mixing space 20a, allowing the detergent mixed solution to further dissolve during the flow process, thereby improving the mixing effect.

[0148] In some embodiments, the mixing space 20a is located on the left or right side of the dispenser box 140. The mixing space 20a and the dispenser box 140 are arranged in the left-right direction, which can reduce the size occupied by the mixing space 20a and the dispenser box 140 in the vertical direction, thereby avoiding excessively increasing the overall height of the workbench 80 in the vertical direction.

[0149] For some examples, see Figures 1 to 16 The dispenser box 140 forms an outlet 140b that is connected to the detergent delivery chamber 140a. The outlet 140b is located on the side of the dispenser box 140 away from the liquid outlet 20ab. The outlet 140b is used to discharge the detergent mixed solution in the detergent delivery chamber 140a. The outlet 140b is connected to the mixing space 20a. For example, the first water channel 40A is connected to the outlet 140b and the mixing space 20a. The detergent mixed solution from the outlet 140b first enters the mixing space 20a through the first water channel 40A, and then is discharged into the clothing processing chamber through the liquid outlet 20ab. The outlet 140b is located on the side of the dispenser box 140 away from the liquid outlet 20ab. The path between the outlet 140b and the liquid outlet 20ab is moderate, which extends the flow path of the detergent mixed solution within a limited space. The flow distance and flow time of the detergent mixed solution are appropriate, which facilitates the further dissolution of the detergent mixed solution during the flow process, thereby improving the mixing effect.

[0150] For example, in some embodiments, the discharge port 140b is formed on the rear side wall of the dispenser box 140, and the liquid outlet 20ab is formed on the front side wall of the workbench 80 facing the clothing loading port 80a.

[0151] For some examples, see Figures 1 to 16 The sub-chamber includes a receiving chamber 30e and a mixing chamber 30d, with the mixing chamber 30d located below the receiving chamber 30e. A filter hole 160a is formed on the upper sidewall of the mixing chamber 30d, connecting the receiving chamber 30e and the mixing chamber 30d. The dispenser box 140 allows access to the receiving chamber 30e. The detergent mixed solution from the detergent dispensing chamber 140a first flows through the receiving chamber 30e, is filtered through the filter hole 160a, and then enters the mixing chamber 30d.

[0152] In this embodiment, taking the detergent as washing powder as an example, the water flow impacts and dissolves the washing powder in the detergent delivery chamber 140a. Since the water flow impacts the washing powder in the detergent delivery chamber 140a for a short time, the problem of insufficient dissolution of the washing powder is likely to occur. The filter hole 160a can temporarily retain particles larger than or equal to the aperture of the filter hole 160a on the upper side wall of the mixing chamber 30d, while particles smaller than the aperture of the filter hole 160a can enter the mixing chamber 30d and then enter the clothing processing chamber through the liquid outlet 20ab. During the washing process, the detergent mixed solution from the washing delivery chamber can repeatedly rinse the washing powder on the upper side wall of the mixing chamber 30d, so that the washing powder dissolves again and then enters the mixing chamber 30d. This design makes the washing powder dissolution effect better, and the particles of washing powder entering the clothing processing chamber are relatively small, thereby improving the cleaning effect.

[0153] For some examples, see Figures 1 to 16 The dispensing assembly includes a filter plate 160, which forms the upper sidewall of the mixing chamber 30d. Exemplarily, at least a portion of the filter plate 160 is located between the detergent dispensing chamber 140a and the lower surface of the sub-chamber. Specifically, the space defined by the filter plate 160 and the lower surface of the sub-chamber defines the mixing chamber 30d. The filter plate 160 is used to filter the mixed detergent solution from the detergent dispensing chamber 140a. The mixed detergent solution from the detergent dispensing chamber 140a first flows through the filter plate 160, is filtered by the filter plate 160, and then enters the mixing chamber 30d.

[0154] In this embodiment, taking the detergent as washing powder as an example, the water flow impacts and dissolves the washing powder in the detergent delivery chamber 140a. Since the water flow impacts the washing powder in the detergent delivery chamber 140a for a short time, the problem of insufficient dissolution of the washing powder is likely to occur. The filter plate 160 can temporarily retain particles larger than or equal to the aperture of the filter hole 160a on the upper surface of the filter plate 160, while particles smaller than the aperture of the filter hole 160a can enter the mixing chamber 30d and then enter the clothing processing chamber through the liquid outlet 20ab. During the washing process, the detergent mixed solution from the washing delivery chamber can repeatedly rinse the washing powder on the upper surface of the filter plate 160, so that the washing powder is dissolved again and then enters the mixing chamber 30d. This design makes the washing powder dissolution effect better, and the particles of washing powder entering the clothing processing chamber are relatively small, thereby improving the cleaning effect.

[0155] It is understood that the pore size and shape of the filter hole 160a can be set as needed. The shape of the filter hole 160a includes but is not limited to circular, elliptical, polygonal or irregular shapes, etc. Irregular shapes refer to irregular shapes.

[0156] In some embodiments, when the dispenser box 140 is stored in the detergent box 30, the projection of the outlet 140b and the projection of the filter holes 160a, as projected along a plane perpendicular to the vertical direction, do not overlap. In other words, the projection of the outlet 140b and the projection of the filter holes 160a are spaced apart. This design allows the fluid from the outlet 140b to first contact the solid portion of the filter plate 160 without the filter holes 160a before flowing to the filter holes 160a. This can, to a certain extent, prevent the detergent mixture from the outlet 140b from directly impacting the filter holes 160a, potentially causing particles larger than the filter holes 160a to be flushed into the mixing chamber 30d.

[0157] For some examples, see Figure 6At least a portion of the lower surface of the mixing chamber 30d slopes downward from away from the nozzle 130 toward the nozzle 130, forming a guide surface 130ba. This allows the fluid in the mixing chamber 30d to flow smoothly and quickly into the nozzle 130 under the guidance of the guide surface 130ba, and reduces residual fluid in the mixing chamber 30d.

[0158] For some examples, see Figure 5 and Figure 6 The filter plate 160 may be located above the guide surface 130ba. For example, with a plane perpendicular to the up-down direction as a projection plane, the projection of the filter plate 160 and the projection of the guide surface 130ba at least partially overlap.

[0159] In one embodiment, please refer to Figure 8 and Figure 11 The pressurizing structure 120 includes a diameter-reducing section 22, which increases the flow rate of the water outlet end 50Aa of the liquid flow channel 130a. The water outlet end 50Aa of the liquid flow channel 130a is the water outlet end of the second waterway 50A. The diameter-reducing section 22 means that along the flow direction of the fluid, the flow area of ​​the fluid in the diameter-reducing section 22 becomes smaller. By limiting the flow area of ​​the fluid, the diameter-reducing section 22 can increase the impact force of the fluid and achieve a good mixing effect. At the same time, the diameter-reducing section 22 enables the water outlet end 50Aa of the liquid flow channel 130a to have a larger injection speed, and can generate obvious negative pressure in a relatively large surrounding area, so that the fluid at the water outlet end 40Aa of the liquid outlet channel 130b is sucked in under the action of the negative pressure and mixed with the fluid in the liquid flow channel 130a, thereby improving the mixing effect.

[0160] In some embodiments, the pressurizing structure 120 includes a powered pressurizing mechanism. This refers to a mechanism that uses a power source to increase fluid pressure and thereby increase flow rate. The power source includes, but is not limited to, electricity or other energy sources. This powered pressurizing mechanism can actively increase fluid flow rate, providing a higher degree of automation compared to the passive increase in fluid flow rate achieved by the reduced diameter section 22.

[0161] The type of the power pressurizing mechanism is not limited. For example, the power pressurizing mechanism includes but is not limited to a water pump, a peristaltic pump, and the like.

[0162] In some embodiments, the end of the pressurizing structure 120 forms the outlet of the second water channel 50A. In other words, the fluid in the second water channel 50A is directly ejected from the end of the pressurizing structure 120 , such as the end of the reduced diameter section 22 .

[0163] For some examples, see Figure 8 and Figure 11 The end of the pressurizing structure 120 is connected to the equal diameter section 23 and / or the expanded diameter section, and the equal diameter section 23 and / or the expanded diameter section form the water outlet end of the second waterway 50A.

[0164] For example, the end of the pressurizing structure 120 is connected to a constant diameter section 23 , and the constant diameter section 23 forms the water outlet end of the second water channel 50A.

[0165] For another example, the end of the pressurizing structure 120 is connected to an expanded diameter section, which forms the water outlet end of the second water channel 50A.

[0166] For another example, the end of the pressurizing structure 120 is connected to the constant diameter section 23 and the expanded diameter section, and either the constant diameter section 23 or the expanded diameter section forms the water outlet end of the second water channel 50A.

[0167] The constant diameter section 23 means that the flow area of ​​the fluid in the constant diameter section 23 remains substantially unchanged along the flow direction of the fluid.

[0168] The expanded diameter section refers to the section where the flow area of ​​the fluid becomes larger along the flow direction of the fluid.

[0169] In this embodiment, the fluid in the second waterway 50A is ejected directly from the constant diameter section 23 and / or the expanded diameter section into the mixing space 20a. The fluid, accelerated by the pressurizing structure 120, then flows through the constant diameter section 23 and / or the expanded diameter section, where it can diverge into the mixing space 20a at a relatively high speed in a conical shape.

[0170] In some embodiments, the length of the constant diameter section 23 extending along the second waterway 50A is less than or equal to the length of the reduced diameter section 22 extending along the second waterway 50A. Because the longer the flow path of a fluid, the more significant its energy loss is, limiting the length of the constant diameter section 23 can reduce the loss of impact force after the fluid flows out of the reduced diameter section 22.

[0171] In some embodiments, the length of the expanded section along the second waterway 50A is less than or equal to the length of the reduced section 22 along the second waterway 50A. Because a longer fluid flow path results in greater energy loss, limiting the length of the expanded section can reduce the impact force loss after the fluid flows out of the reduced section 22.

[0172] For some examples, see Figure 8 and Figure 11 The turbulence structure 21 includes one or more spiral blades that guide the fluid in the liquid flow channel 130a in a spiral motion. A spiral blade is a blade having a helical shape and extending 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 flow disturbance effect on the fluid, and low resistance, thereby reducing energy loss during the passage of the fluid.

[0173] Exemplarily, the turbulent flow structure 21 includes one or more spiral blades, which divide at least a partial length of the second water channel 50A where the spiral blades are located into a plurality of sub-flow channels.

[0174] The above-mentioned multiple refers to the number of blades being multiple, which can be two, three or more, that is, the number of heads of the spiral is not less than two, and does not limit the number of turns of the spiral.

[0175] For some examples, see Figure 8 and Figure 11 The outer edge of the spiral blade along the spiral direction is connected to the inner wall of the liquid flow channel 130a, and the inner edge of the spiral blade along the spiral direction is spaced apart from the inner wall of the liquid flow channel 130a. In other words, there is a gap between the inner edge of the spiral blade and the inner wall of the liquid flow channel 130a. In this way, the inner wall of the liquid flow channel 130a provides connection support for the spiral blade.

[0176] For some examples, see Figure 8 and Figure 11 The pressurizing structure 120 is located downstream of the turbulent structure 21. The fluid passes through the turbulent structure 21 and the pressurizing structure 120, such as the diameter-reducing section 22, and then is ejected into the laundry processing chamber in a conical shape.

[0177] In some embodiments, the distance between the turbulent structure 21 and the pressurizing structure 120 is greater than the distance between the liquid outlet 20ab and the pressurizing structure 120. With this design, the fluid path between the turbulent structure 21 and the pressurizing structure 120 is greater than the fluid path between the pressurizing structure 120 and the liquid outlet 20ab. The fluid can be effectively accelerated by the turbulent structure 21 and the pressurizing structure 120 and can be discharged from the mixing space 20a in a timely manner, reducing losses during the flow process.

[0178] It should be noted that in the embodiments of the present application, the first waterway 40A refers to the flow path of the fluid, not specifically a pipeline structure. The second waterway 50A refers to the flow path of the fluid, not specifically a pipeline structure. The overflow waterway 180A refers to the flow path of the fluid, not specifically a pipeline structure.

[0179] In some embodiments, the water inlet end of the first water channel 40A may be connected to a water source, and the water inlet end of the second water channel 50A may be connected to a water source.

[0180] It should be noted that the water source in the embodiment of the present application refers to the water source that supplies water to the first water channel 40A and / or the second water channel 50A, such as tap water; it can also be the internal water source of the clothing processing equipment, such as circulating water.

[0181] In one embodiment, please refer to Figure 1 、 Figure 4 and Figure 16The laundry processing apparatus includes a water inlet valve 90, which is connected to a water source, such as a tap water pipe. The first water channel 40A and the second water channel 50A can be connected to different water inlet valves 90, or they can be connected to the same water inlet valve 90, without limitation. As an optional embodiment, the laundry processing apparatus includes a circulation pump, with one of the first water channel 40A and the second water channel 50A connected to the water inlet valve 90, and the other connected to the circulation pump of the laundry processing apparatus.

[0182] In some embodiments, the water inlet valve 90 has at least two water inlets, with the first water channel 40A and the second water channel 50A each connected to one of the water inlets. A water source supplies water to the laundry processing apparatus through the water inlet valve 90 . The first water channel 40A and the second water channel 50A each connect to one of the water inlets. The water flow rates at the different water inlets can differ, thereby increasing the flow rate difference between the first water channel 40A and the second water channel 50A.

[0183] In some embodiments, the water inlet end of the cannula 131 is connected to a water supply port of the water inlet valve 90. In this way, the water inlet valve 90 can supply water to the cannula 131. The second waterway 50A includes the cannula 131, and the water inlet valve 90 supplies water to the cannula 131.

[0184] In some embodiments, a water inlet of the water inlet valve 90 can be connected to a water spray structure having a water spray port that sprays water toward the detergent dispensing chamber 140a. The first water channel 40A includes the detergent dispensing chamber 140a and the first water channel 40A. Thus, the detergent dispensing chamber 140a is flushed with water to achieve initial dissolution of the detergent solution. The detergent mixed solution in the detergent dispensing chamber 140a flows into the first water channel 40A under the action of the water flow.
