DETAILED DESCRIPTION

[0036] In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other. The detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0037] It should be noted that, in the embodiments of the present application, down refers to the direction of the ground, and up is opposite to down; front refers to the direction toward the user, and back is opposite to front; left is the side where the left hand of the user is located when the user is in front of the clothing processing device, and right is opposite to left; the up and down directions, the front and back directions, and the left and right directions are perpendicular to each other. In the embodiments of the present application, the orientation or positional relationship of "up", "down", "front", "back", "left", and "right" is based on the orientation or positional relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] In the embodiments of the present application, "a plurality" refers to a number including two or more, and "at least two" refers to a number including two or more.

[0039] The functions of the clothes processing device provided in the embodiments of the present application are not limited. For example, the clothes processing device may have a drying function in addition to a washing function. The drying function may be used to dry clothes.

[0040] The clothes processing device may be a drum-type clothes processing device, such as a drum washing machine or a drum washer-dryer.

[0041] The clothes treating device comprises a clothes treating chamber, and the clothes treating chamber is used for placing clothes.

[0042] The laundry processing chamber of the drum type laundry processing device rotates around an axis extending in a horizontal direction or an inclined direction. The inclined axis refers to an axis of the laundry processing chamber that is oblique to the horizontal direction.

[0043] See also Figure 1 The laundry processing apparatus may include a barrel assembly 10. The axis of the barrel assembly 10 may extend in a horizontal direction or an inclined direction. The interior space of the barrel assembly 10 may be at least a portion of a laundry processing chamber.

[0044] For some examples, see Figure 1 and Figure 2 The clothes processing device may include a door sealing ring 60 , the axis of the barrel assembly 10 extends in a horizontal direction or an inclined direction, and the door sealing ring 60 may be arranged at the front end of the barrel assembly 10 .

[0045] In some embodiments, the drum assembly 10 includes a rotatable inner drum with an access opening. The access opening can face forward, and the inner drum can be used to place loads such as clothing. Users can insert or remove clothing from the inner drum from the front through the space enclosed by the door seal 60 and the access opening. The inner drum can rotate, for example, so that clothing, liquids, detergents, etc. rotate with the inner drum. This allows the clothing to continuously change position within the inner drum, and fluids such as liquids and detergents to change direction as they flow.

[0046] In some embodiments, the inner cylinder may be substantially in the shape of a hollow cylinder.

[0047] For some examples, see Figure 1 The barrel assembly 10 includes an outer barrel 11, and the inner barrel can be arranged in the outer barrel 11. The outer barrel 11 can be used to hold water for washing clothes, and the inner barrel is used to hold clothes.

[0048] In this embodiment, the outer tub 11 holds water, and the inner tub can also be called a perforated inner tub. The space within the inner tub forms at least a portion of the laundry treatment chamber. Fluid can flow between the space between the outer tub 11 and the inner tub and the space within the inner tub through the flow holes in the inner tub.

[0049] For some examples, see Figure 1 , the outer barrel 11 can be roughly in the shape of a hollow cylinder.

[0050] In some embodiments, the inner cylinder holds water by itself and can also be called a non-porous inner cylinder. An outer cylinder 11 can be provided outside the inner cylinder or not.

[0051] It is understood that in some embodiments, the drum assembly 10 may only include an inner drum, without the outer tub 11. In such embodiments, the inner drum is a non-porous inner drum capable of holding water. The inner drum may be a single drum structure. In other words, the laundry processing device may only include the inner drum.

[0052] In some embodiments, the clothes processing apparatus includes a housing, the barrel assembly 10 is disposed in the housing, and the housing is provided with an opening communicating with the inner space of the barrel assembly 10 .

[0053] In some embodiments, the box may be substantially in the shape of a hexahedron, for example, a cube or a cuboid.

[0054] In some embodiments, the clothing processing device includes a door body, which is used to selectively open or close the opening of the box body. The axis of the barrel assembly 10 extends in a horizontal direction or an inclined direction. The door sealing ring 60 can be used to seal the gap between the barrel assembly 10 and the opening of the box body. The connecting space formed inside the door body, the door sealing ring 60 and the barrel assembly 10 constitutes a clothing processing chamber.

[0055] An embodiment of the present application provides a detergent dispensing device, which is used in a clothing processing device.

[0056] See also Figures 10 to 12 The detergent dispensing device includes a first water channel 40A and a liquid flow channel 130a. The sidewall of the first water channel 40A is open to form a liquid outlet 20ab. The first water channel 40A includes a mixing space 20a. The liquid flow channel 130a has a second water outlet 50Aa. At least one of the first water channel 40A and the liquid flow channel 130a delivers a mixed detergent solution. The second water outlet 50Aa is connected to the liquid outlet 20ab via the mixing space 20a.

[0057] The second water outlet 50Aa is connected to the liquid outlet 20ab through the mixing space 20a. That is, the fluid discharged from the second water outlet 50Aa first enters the mixing space 20a, mixes with the fluid in the mixing space 20a, and then is discharged from the liquid outlet 20ab to the clothing processing chamber.

[0058] At least one of the first water channel 40A and the liquid flow channel 130a transports a detergent mixed solution. For example, the first water channel 40A transports a detergent mixed solution, and the liquid flow channel 130a transports other fluids. For another example, the liquid flow channel 130a transports a detergent mixed solution, and the first water channel 40A transports other fluids. For another example, both the first water channel 40A and the liquid flow channel 130a transport a detergent mixed solution.

[0059] 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.

[0060] It can be understood that the first water channel 40A and the liquid flow channel 130a are both used to transport fluids, and the detergent mixed solution and water are both fluids.

[0061] The fluid in the mixing space 20a includes but is not limited to a detergent mixed solution of detergent and water. The liquid outlet 20ab is used to discharge the fluid in the mixing space 20a.

[0062] The detergent dispensing device provided in the embodiment of the present application has a side wall opening of the first water channel 40A to form a liquid outlet 20ab, simplifying the dispensing structure. The second water outlet end 50Aa is connected to the liquid outlet 20ab through the mixing space 20a. The fluid discharged from the second water outlet end 50Aa enters the mixing space 20a to converge and mix with the fluid in the first water channel 40A, thereby improving the mixing effect and allowing detergents such as washing powder to be more fully dissolved.

[0063] In one embodiment, please refer to Figures 10 to 12First waterway 40A includes a liquid outlet channel 130b having a first outlet end 40Aa that communicates with mixing space 20a. In other words, liquid outlet channel 130b is located upstream of mixing space 20a along the direction of fluid flow in first waterway 40A. Fluid in liquid outlet channel 130b enters mixing space 20a through first outlet end 40Aa.

[0064] For some examples, see Figures 10 to 12 The sidewall of the liquid outlet channel 130b is opened to form a first water outlet end 40Aa. The liquid flow channel 130a is located on the side of the liquid outlet channel 130b where the first water outlet end 40Aa is located. In other words, the first water outlet end 40Aa and the liquid flow channel 130a are located on the same side of the liquid outlet channel 130b.

[0065] At least one of the first water outlet 40Aa and the second water outlet 50Aa outputs a mixed detergent solution. For example, both the first water outlet 40Aa and the second water outlet 50Aa output a mixed detergent solution. For another example, the first water outlet 40Aa outputs a mixed detergent solution, and the second water outlet 50Aa outputs another fluid. For another example, the second water outlet 50Aa outputs a mixed detergent solution, and the first water outlet 40Aa outputs another fluid.

[0066] 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. Its 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 water from a water source.

[0067] The functions of detergents are not limited, and include but are not limited to cleaning, softening and / or fragrance enhancement, etc.

[0068] The type of detergent is not limited, and the detergent includes but is not limited to detergent, softener and / or fragrance, etc.

[0069] The form of the detergent is not limited, and it can be powdered laundry detergent or flowable laundry liquid.

[0070] In this embodiment, the side wall of the liquid outlet channel 130b is opened to form a first water outlet end 40Aa, and the liquid flow channel 130a is located on the side of the liquid outlet channel 130b where the first water outlet end 40Aa is located. In this way, the fluid output by the first water outlet end 40Aa flows roughly toward the location of the liquid flow channel 130a, so that the fluid output by the first water outlet end 40Aa can contact the fluid output by the second water outlet end 50Aa as soon as possible.

[0071] It should be noted that the first water outlet end 40Aa refers to the part where the fluid in the liquid flow channel 130b leaves the liquid outlet channel 130b, and the second water outlet end 50Aa refers to the part where the fluid in the liquid flow channel 130a leaves the liquid flow channel 130a. The mixing space 20a can be a chamber formed in the physical structure.

[0072] The present embodiment provides a laundry processing device, comprising the detergent dispensing device and a laundry processing chamber according to any of the embodiments of the present invention, wherein the liquid outlet 20ab delivers fluid into the laundry processing chamber. In other words, the fluid delivered by the first waterway 40A and the liquid flow channel 130a ultimately enters the laundry processing chamber for processing the laundry.

[0073] In one embodiment, please refer to Figure 12 Liquid outlet channel 130b includes a diverging section, the largest flow area of ​​which is located at first outlet end 40Aa. In other words, the fluid in liquid outlet channel 130b is ultimately ejected from the diverging section into mixing space 20a. The diverging section reduces head loss and facilitates rapid discharge of the fluid from liquid outlet channel 130b.

[0074] It should be noted that the flow cross-section is a cross-section perpendicular to the streamline cluster. When the streamline clusters are nonparallel, 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.

[0075] In one embodiment, the flow area of ​​the expansion section gradually increases from away from the first water outlet 40Aa toward closer to the first water outlet 40Aa. Guided by the expansion section, the fluid tends to concentrate near the mixing space 20a, filling the mixing space 20a as much as possible and thoroughly mixing with the fluid discharged from the second water outlet 50Aa.

[0076] In one embodiment, please refer to Figures 10 to 12 , the area of ​​the first water outlet end 40Aa is larger than the area of ​​the second water outlet end 50Aa, and the area of ​​the first water outlet end 40Aa is smaller than the area of ​​the liquid outlet 20ab. The liquid outlet 20ab is used to discharge the fluid in the mixing space 20a. The fluid transported by the liquid outlet channel 130b and the fluid transported by the liquid flow channel 130a converge and mix in the mixing space 20a, and the mixed fluid is discharged from the liquid outlet 20ab and enters the clothing processing chamber to participate in clothing processing. Such a design can effectively suppress the backflow phenomenon caused by the excessive flow difference between the first water outlet end 40Aa and the second water outlet end 50Aa, and prevent the fluid in the mixing space 20a from flowing back into the liquid outlet channel 130b as much as possible.

[0077] It should be noted that the area of ​​the first water outlet 40Aa refers to the flow area of ​​the first water outlet 40Aa, the area of ​​the second water outlet 50Aa refers to the flow area of ​​the second water outlet 50Aa, and the area of ​​the liquid outlet 20ab refers to the flow area of ​​the liquid outlet 20ab.

[0078] In one embodiment, please refer to Figures 10 to 12 The liquid flow channel 130a is provided with a pressurizing structure 120, and the pressurizing structure 120 is used to increase the flow rate of the fluid. For example, the pressurizing structure 120 is used to increase the flow rate of the fluid in the liquid flow channel 130a.

[0079] In this embodiment, the pressurizing structure 120 increases the speed of the fluid in the liquid flow channel 130a, and there is a flow rate difference between the fluid in the liquid outlet channel 130b and the fluid in the liquid flow channel 130a. For example, the fluid in the liquid flow channel 130a is accelerated by the pressurizing structure 120, and the flow rate of the second water outlet end 50Aa is greater than the flow rate of the first water outlet end 40Aa. The flow rates of the two fluids entering the mixing space 20a are one fast and the other slow, and 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.

[0080] In one embodiment, please refer to Figures 10 to 12 The pressurizing structure 120 includes a reduced diameter section 22, which increases the flow rate of the second water outlet end 50Aa. The reduced diameter section 22 means that along the flow direction of the fluid, the flow area of ​​the fluid in the reduced diameter section 22 becomes smaller. By limiting the flow area of ​​the fluid, the reduced diameter section 22 can increase the impact force of the fluid and achieve a good mixing effect. At the same time, the reduced diameter section 22 enables the second water outlet end 50Aa to have a larger injection speed, and can generate a significant negative pressure in a relatively large surrounding area, so that the fluid of the first water outlet end 40Aa is sucked in under the action of the negative pressure and mixed with the fluid discharged from the second water outlet end 50Aa, thereby improving the mixing effect.

[0081] 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.

[0082] 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.

[0083] In some embodiments, the end of the pressurizing structure 120 forms the second water outlet 50Aa. In other words, the fluid in the second waterway 50A is directly ejected from the end of the pressurizing structure 120, such as the reduced diameter section 22.

[0084] For some examples, see Figures 10 to 12 The end of the pressurizing structure 120 is connected to a constant diameter section 23 and / or an expanded diameter section, and the constant diameter section 23 and / or the expanded diameter section forms a second water outlet end 50Aa.

[0085] 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 second water outlet end 50Aa.

[0086] For another example, the end of the pressurizing structure 120 is connected to an expanded diameter section, which forms the second water outlet end 50Aa.

[0087] For another example, the end of the pressurizing structure 120 is connected to a constant diameter section 23 and an expanded diameter section, and either the constant diameter section 23 or the expanded diameter section forms the second water outlet end 50Aa.

[0088] 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.

[0089] The expanded diameter section refers to the section where the flow area of ​​the fluid becomes larger along the flow direction of the fluid.

[0090] In this embodiment, the fluid in the liquid flow channel 130a 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.

[0091] 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.

[0092] 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.

[0093] In one embodiment, please refer to Figures 10 to 12 The distal end of the pressurizing structure 120 extends into the mixing space 20a. This extends into the mixing space 20a to accelerate the fluid entering the mixing space 20a. The fluid, accelerated by the pressurizing structure 120, enters the mixing space 20a through the distal end of the pressurizing structure 120. The increased impact force of the accelerated fluid enhances agitation within the mixing space 20a, improving the mixing effect and the cleaning efficiency.

[0094] In one embodiment, please refer to Figures 10 to 12 The liquid flow channel 130a is provided with a turbulent flow structure 21, and the turbulent flow structure 21 is used to provide a circumferential velocity component to the fluid. For example, the turbulent flow structure 21 is used to provide a circumferential velocity component to the fluid in the liquid flow channel 130a.

[0095] 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.

[0096] After passing through the turbulent structure 21, the fluid in the liquid flow channel 130a produces a composite motion in multiple directions, such as the circumferential direction and the forward direction, so as to better mix with the fluid in the mixing space 20a and improve the mixing efficiency; it can also make the fluid ejected from the liquid outlet 20ab disperse roughly in a cone shape, with a wider radiation range and better visual effect.

[0097] It is understood that the turbulent flow structure 21 can also increase the flow rate of the fluid by limiting the flow area of ​​the liquid flow channel 130a in which it is located. In this way, the speed difference between the two fluids entering the mixing space 20a is further increased, further promoting the dissolution of the detergent.

[0098] In one embodiment, please refer to Figures 10 to 12 The turbulence structure 21 includes one or more spiral blades, which are used to guide the fluid in spiral motion. For example, the spiral blades are used to guide the fluid in the liquid flow channel 130a in spiral motion. A spiral blade is a blade having a helical shape, 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 turbulence effect on the fluid, and low resistance, thereby reducing energy loss during the passage of the fluid.

[0099] Illustratively, the turbulent flow structure 21 includes one or more spiral blades, which divide at least a portion of the length of the liquid flow channel 130a where the spiral blades are located into a plurality of sub-flow channels.

[0100] The above-mentioned multiple refers to the number of spiral blades being multiple, which can be two, three or more, that is, the number of heads of the spiral line is not less than two, and does not limit the number of turns of the spiral line.

[0101] For some examples, see Figures 10 to 12 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.

[0102] In one embodiment, please refer to Figures 10 to 12 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 reduced diameter section 22, and then is ejected into the mixing space 20a in a conical shape.

[0103] In one embodiment, the liquid outlet channel 130b is used to transport the detergent mixed solution, and the liquid flow channel 130a is used to transport water.

[0104] In this embodiment, the liquid outlet channel 130b delivers a mixed detergent solution, such as a laundry liquid solution or a laundry powder solution, particularly a laundry powder solution. Because laundry powder is a powdered detergent and is more susceptible to clogging and residue than liquid laundry, the liquid outlet channel 130b delivers the mixed detergent solution. The pressurizing structure 120 and / or the turbulent flow structure 21 are disposed within the liquid flow channel 130a. Liquid flow channel 130a is used to deliver water from a source, thereby preventing the pressurizing structure 120 and / or the turbulent flow structure 21 from contacting the laundry powder to a certain extent.

[0105] In one embodiment, please refer to Figures 10 to 12 The detergent dispensing device includes a nozzle 130, which is formed with a liquid outlet channel 130b, a liquid flow channel 130a, and a mixing space 20a. A liquid outlet 20ab extends through the outer surface of the side wall of the nozzle 130, and at least a portion of the liquid flow channel 130a extends into the mixing space 20a. In other words, the fluid in the mixing space 20a is sprayed into the laundry processing chamber through the liquid outlet 20ab of the nozzle 130. At least a portion of the liquid flow channel 130a extends into the mixing space 20a, which can better agitate the fluid in the mixing space 20a and enhance the mixing effect of the fluid in the mixing space 20a.

[0106] In one embodiment, please refer to Figures 10 to 12 The portion of the liquid flow channel 130a located in the mixing space 20a extends along the first direction, and the liquid outlet channel 130b is located on one side of the liquid flow channel 130a along the second direction, and the first direction and the second direction intersect. In this way, the fluid discharged from the liquid flow channel 130a enters the mixing space 20a approximately along the first direction, and the fluid discharged from the liquid outlet channel 130b enters the mixing space 20a approximately along the second direction. The flow directions of the two fluids intersect, which can enhance the impact effect. When the flow rate of the fluid discharged from the liquid flow channel 130a is greater than the flow rate of the fluid discharged from the liquid outlet channel 130b, negative pressure will be generated near the second water outlet end 50Aa, so that the fluid at the first water outlet end 40Aa is sucked under the action of the negative pressure and changes its flow direction to flow in the first direction, and foam is generated in the fluid, thereby enhancing the mixing uniformity of detergents such as washing powder.

[0107] For example, the pressurizing structure 120 may be formed at a portion of the liquid flow channel 130a located within the mixing space 20a. The turbulent flow structure 21 may be formed at a portion of the liquid flow channel 130a located within the mixing space 20a.

[0108] In one embodiment, please refer to Figures 10 to 12 The nozzle 130 includes a housing 132 and a cannula 131. The housing 132 defines a liquid outlet channel 130b, a mixing space 20a, and a liquid outlet 20ab. At least a portion of the cannula 131 is inserted into the mixing space 20a, and the cannula 131 defines a liquid flow channel 130a. Specifically, the liquid outlet 20ab extends through the outer surface of the sidewall of the housing 132, and the second water outlet 50Aa is formed in the cannula 131. Exemplarily, the end of the cannula 131 located within the mixing space 20a is the second water outlet 50Aa. The nozzle 130 has a simple structure and is easy to manufacture.

[0109] In some embodiments, the nozzle 130 may be an integrally formed structure. For example, the nozzle 130 may be an integrally formed injection molded structure.

[0110] For example, in one embodiment, please refer to Figures 10 to 12 The end of the cannula 131 facing the first direction is the second water outlet 50Aa. The first water outlet 40Aa is formed on the sidewall of the mixing space 20a along the second direction. With this design, the fluid discharged from the first water outlet 40Aa flows generally in the first direction, while the fluid discharged from the second water outlet 50Aa flows generally in the second direction. The two fluids intersect and mix in the mixing space 20a.

[0111] In one embodiment, please refer to Figures 10 to 12 The housing 132 has a liquid outlet 20ab formed on a sidewall along the first direction. For example, the liquid outlet 20ab is formed on the sidewall along the first direction of the housing 132. The fluid in the mixing space 20a is ejected out of the nozzle 130 through the liquid outlet 20ab.

[0112] In one embodiment, please refer to Figure 2 The nozzle 130 is arranged on the door sealing ring 60. The door sealing ring 60 can not only provide an installation position for the nozzle 130, but also make the detergent mixed solution sprayed by the nozzle 130 closer to the clothes processing chamber.

[0113] In some embodiments, the spray head 130 may be detachably connected to the door seal 60 or may be non-detachably connected to the door seal 60 .

[0114] In one embodiment, please refer to Figure 1 and Figure 2The space enclosed by the door seal 60 is part of the clothing processing chamber, and the liquid outlet 20ab extends radially inwardly of the door seal 60. The fluid discharged from the liquid outlet 20ab can directly enter the space enclosed by the door seal 60, and thus directly enter the clothing processing chamber.

[0115] It should be noted that the extending direction of the axis of the door sealing ring 60 is consistent with the extending direction of the axis of the cylinder assembly 10 , and the axis of the door sealing ring 60 may extend in a horizontal direction or an inclined direction.

[0116] In one embodiment, please refer to Figures 10 to 12 The detergent dispensing device includes a nozzle 130, which has a mixing space 20a. A liquid outlet 20ab extends through the outer surface of the sidewall of the nozzle 130. The nozzle 130 forms the mixing space 20a, meaning that the fluid in the liquid outlet channel 130b and the fluid in the liquid flow channel 130a meet and mix within the nozzle 130. Liquid outlet 20ab extends through the outer surface of the sidewall of the nozzle 130, and the fluid within the nozzle 130 is ejected through the liquid outlet 20ab. Thus, the fluids from the two waterways are sprayed into the laundry treatment chamber through the nozzle 130.

[0117] In one embodiment, please refer to Figures 10 to 12 , see Figures 10 to 12 The nozzle 130 forms a liquid outlet 20ab on the side wall along the first direction, and the first water outlet end 40Aa is formed on the side wall of the mixing space 20a along the second direction, and the first direction and the second direction intersect.

[0118] In this embodiment, the liquid outlet 20ab is formed on the side wall of the nozzle 130 along the first direction, and the first water outlet end 40Aa is formed on the side wall of the mixing space 20a along the second direction. That is to say, the fluid discharged from the first water outlet end 40Aa enters the mixing space 20a roughly along the second direction, and after mixing with the fluid from the second water outlet end 50Aa, is sprayed out roughly along the first direction through the liquid outlet 20ab. The flow path of the fluid discharged from the first water outlet end 40Aa can be appropriately increased to improve the mixing effect.

[0119] In one embodiment, the liquid outlet 20ab is directly connected to the laundry processing chamber. Direct connection between the liquid outlet 20ab and the laundry processing chamber means that the liquid outlet 20ab opens into the laundry processing chamber, and the fluid from the liquid outlet 20ab enters the laundry processing chamber directly. There is no intermediate channel between the liquid outlet 20ab and the laundry processing chamber, such as a transfer pipe or other structure for fluid circulation. The fluid from the liquid outlet 20ab does not need to be guided through an intermediate channel; instead, it is directly discharged into the laundry processing chamber under the influence of its own gravity and flow rate.

[0120] In this embodiment, the liquid outlet 20ab is directly connected to the clothing processing chamber, and the fluid from the liquid outlet 20ab directly enters the clothing processing chamber. There is no need to set a transfer channel between the liquid outlet 20ab and the clothing processing chamber, which saves the transfer channel and reduces production costs; the fluid, such as the detergent mixed solution, can directly enter the clothing processing chamber from the liquid outlet 20ab and directly act on the clothes.

[0121] It can be understood that the liquid outlet 20ab can pass through the outer surface of the physical structure where it is located.

[0122] In one embodiment, the liquid outlet 20ab can also be connected to a transfer channel. That is, the outer surface of the solid structure where the liquid outlet 20ab is located is connected to the transfer channel, and the fluid from the liquid outlet 20ab flows through the transfer channel before entering the clothing processing chamber. The transfer channel can be used to change the flow direction and / or shape of the fluid, allowing the fluid to be sprayed at specific locations on clothing and / or in a specific shape.

[0123] In one embodiment, please refer to Figure 2 The liquid outlet 20ab is located in the laundry processing chamber. For example, the liquid outlet 20ab extends radially inward of the door seal 60. In this way, the liquid outlet 20ab is closer to the laundry in the laundry processing chamber, reducing the probability of defoaming in the fluid ejected from the liquid outlet 20ab.

[0124] In one embodiment, please refer to Figures 10 to 12 The second water outlet end 50Aa faces the liquid outlet 20ab. The second water outlet end 50Aa faces the liquid outlet 20ab, which means that the direction of the second water outlet end 50Aa is the same as that of the liquid outlet 20ab. For example, the second water outlet end 50Aa and the liquid outlet 20ab both face the same side of the first direction.

[0125] In this embodiment, the second water outlet end 50Aa is directed toward the liquid outlet 20ab, and the liquid outlet 20ab is downstream of the flow direction of the fluid discharged from the second water outlet end 50Aa, so that the flow discharged from the second water outlet end 50Aa flows toward the location of the liquid outlet 20ab. The fluid from the second water outlet end 50Aa can flow quickly to the liquid outlet 20ab and be discharged without changing the flow direction as much as possible.

[0126] In one embodiment, please refer to Figures 10 to 12 With the plane of liquid outlet 20ab as the projection plane, the projection of second water outlet 50Aa on the projection plane is within the projection range of liquid outlet 20ab on the projection plane. For example, the flow area of ​​liquid outlet 20ab can be larger than the flow area of ​​second water outlet 50Aa. This prevents misalignment between second water outlet 50Aa and liquid outlet 20ab, which can cause changes in fluid flow direction.

[0127] In one embodiment, please refer to Figures 10 to 12The 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.

[0128] In one embodiment, the projections of the axis of the first water outlet 40Aa and the axis of the second water outlet 50Aa on the horizontal plane intersect. In other words, with the horizontal plane as the projection plane, the projections of the axis of the first water outlet 40Aa and the axis of the second water outlet 50Aa intersect.

[0129] It should be noted that the axis of the first water outlet 40Aa is a straight line passing through the center of the flow section of the first water outlet 40Aa. The axis of the second water outlet 50Aa is a straight line passing through the center of the flow section of the second water outlet 50Aa.

[0130] In this embodiment, the fluid flowing through the liquid outlet channel 130b is roughly ejected along the axis of the first water outlet end 40Aa, and the fluid flowing through the liquid flow channel 130a is roughly ejected along the axis of the second water outlet end 50Aa. The projections of the axis of the first water outlet end 40Aa and the axis of the second water outlet end 50Aa in the horizontal plane intersect. In this way, the fluid ejected from the first water outlet end 40Aa and the fluid ejected from the second water outlet end 50Aa can converge. When the two fluids converge, the two fluids mix and impact, which can further promote the dissolution of detergent, which is beneficial to adding detergent with bubbles to clothes, thereby improving the cleaning effect.

[0131] For some examples, see Figures 3 to 12 The detergent dispensing device includes a first water channel 40A and a second water channel 50A, wherein the liquid outlet channel 130b is a part of the first water channel 40A, the liquid flow channel 130a is a part of the second water channel 50A, and the second water outlet end 50Aa is the water outlet end of the second water channel 50A.

[0132] The first water outlet end 40Aa is the location where the fluid in the liquid outlet channel 130b leaves the liquid outlet channel 130b. The second water outlet end 50Aa is the location where the fluid in the second water channel 50A leaves the second water channel 50A.

[0133] It should be noted that in the embodiment of the present application, the first water channel 40A refers to a flow path of the fluid, and does not specifically refer to a pipeline structure. The second water channel 50A refers to a flow path of the fluid, and does not specifically refer to a pipeline structure.

[0134] 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.

[0135] 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.

[0136] In one embodiment, please refer to Figures 3 to 9 The 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.

[0137] 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 water inlet. A water source supplies water to the laundry processing device through the water inlet valve 90 . The first water channel 40A and the second water channel 50A each connect to one water inlet. The water flow rates at the different water inlets can differ, thereby increasing the flow rate difference between the fluids in the first water channel 40A and the second water channel 50A.

[0138] For some examples, see Figures 3 to 9 The water inlet valve 90 has a first outlet 90a, and the first water channel 40A and the second water channel 50A are both connected to the first outlet 90a. Water is supplied to the laundry processing device through the water inlet valve 90. The first water channel 40A and the second water channel 50A are both connected to the first outlet 90a of the water inlet valve 90. This facilitates the installation of the first water channel 40A and the second water channel 50A, simplifies the configuration of the water inlet valve 90, and saves costs.

[0139] For some examples, see Figures 3 to 12 The detergent dispensing device includes a detergent supply component, which includes a detergent passage and a first drain port 30b. The detergent passage is connected to the atmospheric environment. The first water channel 40A connects the water source, the detergent passage, the first drain port 30b and the liquid outlet 20ab; the second water channel 50A connects the water source and the mixing space 20a.

[0140] The detergent passage refers to a flow path of the detergent within the detergent supply assembly.

[0141] First water channel 40A connects a water source, a detergent passage, first drain port 30b, and liquid outlet 20ab. In other words, the detergent passage, first drain port 30b, and mixing space 20a constitute at least a portion of first water channel 40A. Fluid from the water source flows through the detergent passage and first drain port 30b. For example, fluid from the water source in first water channel 40A flows through the detergent storage area and mixes with the detergent to form a mixed detergent solution. The mixed detergent solution then flows to first drain port 30b, is discharged through first drain port 30b, and flows into mixing space 20a.

[0142] The second water channel 50A does not flow through the first drain port 30 b , and the detergent mixed solution conveyed by the first water channel 40A can merge with the fluid in the second water channel 50A in the mixing space 20 a .

[0143] In this embodiment, the detergent passage is connected to the atmosphere to form a pressure relief space. The water pressure of the fluid in the first water channel 40A at any cross-section at the end of the first water channel 40A connected to the water source is the initial water pressure. When the fluid in the first water channel 40A flows through the detergent passage, the fluid enters the pressure relief space from the closed pipe section, causing the water pressure of the fluid in the first water channel 40A to decrease, i.e., pressure relief occurs. The decompressed fluid flows from the first drain port 30b to the water inlet of the mixing space 20a, resulting in the water pressure of the fluid flowing through the first water channel 40A at any cross-section at the water inlet of the mixing space 20a being lower than the initial water pressure at any cross-section at the end of the first water channel 40A connected to the water source. In other words, the fluid from the water source enters the first water channel 40A at a relatively high pressure and experiences pressure relief in the detergent passage, resulting in the water pressure at the end of the first water channel 40A being lower than the water pressure at its water inlet.

[0144] For some examples, see Figures 3 to 12 The detergent passage includes a mixing chamber 30d, the wall of which forms a first drain port 30b. The detergent supply assembly includes a second drain port 30a and an overflow chamber 30c. The overflow chamber 30c is used to receive the mixed detergent solution overflowing from the detergent passage, and the second drain port 30a is used to drain the mixed detergent solution in the overflow chamber 30c. The first drain port 30b is used to drain the mixed detergent solution in the mixing chamber 30d.

[0145] In this embodiment, when the liquid level in the detergent passage, for example, mixing chamber 30d, is below the overflow level, the fluid in mixing chamber 30d is discharged from first drain port 30b and flows into mixing space 20a. When the liquid level in mixing chamber 30d exceeds the overflow level, the excess fluid overflows into overflow chamber 30c and is discharged from second drain port 30a. In other words, the detergent mixed solution preferentially flows out of first drain port 30b, while second drain port 30a serves as a safety feature, allowing for the timely discharge of excess fluid from mixing chamber 30d.

[0146] For example, the flow area of ​​the second drain outlet 30a is larger than that of the first drain outlet 30b. That is, when the water volume is equally sufficient, the second drain outlet 30a will drain more water than the first drain outlet 30b. Because the flow area of ​​the first drain outlet 30b is smaller, the outflow rate from the first drain outlet 30b is relatively small. However, the second drain outlet 30a and the overflow chamber 30c can promptly drain the detergent mixture or water from the first waterway 40A in the event of overflow, reducing water congestion and providing safety protection.

[0147] In some embodiments, the detergent passage includes a detergent delivery chamber 140a. The detergent delivery chamber 140a can be adapted to accommodate powdered laundry detergent. When the fluid in the first water passage 40A flows through the detergent delivery chamber 140a, the laundry detergent is initially dissolved. Of course, the detergent delivery chamber 140a can also be adapted to accommodate detergents with fluid properties.

[0148] For some examples, see Figures 3 to 12 The detergent supply assembly includes a detergent box 30 and a dispenser box 140 disposed within the detergent box 30. The dispenser box 140 has a detergent dispensing chamber 140a. The detergent box 30 has a mixing chamber 30d and an overflow chamber 30c. The mixing chamber 30d is located below the dispenser box 140 and is used to receive the mixed detergent solution flowing through the detergent dispensing chamber 140a. A first drain port 30b is disposed on the wall of the mixing chamber 30d, and the overflow chamber 30c is used to receive the mixed detergent solution overflowing from the mixing chamber 30d. The detergent box 30 is formed with a second drain port 30a, which is disposed on the wall of the overflow chamber 30c.

[0149] It should be noted that the detergent in the detergent dispensing chamber 140a can flow toward the first drain port 30b under the action of water. For example, an addition port is formed on the upper sidewall of the dispenser box 140, which communicates with the detergent dispensing chamber 140a. When the detergent dispensing chamber 140a is partially located outside the detergent box 30, the user can inject detergent into the detergent dispensing chamber 140a through the addition port. When the detergent dispensing chamber 140a is located inside the detergent box 30, water can flow through the addition port to flush the detergent dispensing chamber 140a, thereby delivering the detergent mixed solution into the mixing chamber 30d.

[0150] The mixing chamber 30d is used to receive the fluid flowing through the detergent delivery chamber 140a, and the first drain port 30b is provided on the wall of the mixing chamber 30d. That is, the detergent mixed solution enters the mixing chamber 30d and is discharged from the first drain port 30b.

[0151] The first drain port 30 b may be formed by the detergent box 30 itself, or may be formed by a water outlet end of a water channel structure additionally provided on the top, side, or bottom of the detergent box 30 .

[0152] In some embodiments, the dispenser box 140 is pullable inside the detergent box 30. For example, the dispenser box 140 is at least partially pulled out of the detergent box 30 to the outside of the detergent box 30, and the user can put detergent into the detergent injection cavity 140a.

[0153] Exemplarily, when the dispenser box 140 is housed in the detergent box 30, the mixing chamber 30d is located below the dispenser box 140, and the detergent mixed solution flows from the detergent delivery chamber 140a of the dispenser box 140 to the mixing chamber 30d below the dispenser box 140, and is discharged from the first drain port 30b.

[0154] In one embodiment, please refer to Figures 3 to 12 The detergent supply assembly includes a water retaining rib 170. The detergent box 30 has a cavity. The water retaining rib 170 extends upward along the wall of the cavity to separate the cavity into a sub-cavity and an overflow chamber 30c. At least part of the sub-cavity is a mixing chamber 30d. The side wall of the mixing chamber 30d forms a first drain port 30b, and the side wall of the overflow chamber 30c forms a second drain port 30a.

[0155] It can be understood that the top of the water retaining rib 170 can be spaced from the upper surface of the cavity, the liquid level of the fluid in the mixing chamber 30d is higher than the height of the water retaining rib 170, and the fluid in the mixing chamber 30d can overflow into the overflow chamber 30c through the gap between the water retaining rib 170 and the upper surface of the cavity.

[0156] In this embodiment, the water retaining rib 170 separates the sub-cavity and the overflow cavity 30c, and the liquid level of the fluid in the mixing cavity 30d is higher than the height of the water retaining rib 170. The fluid in the mixing cavity 30d can overflow into the overflow cavity 30c through the gap between the water retaining rib 170 and the upper surface of the cavity.

[0157] In one embodiment, please refer to Figures 3 to 12 The detergent supply assembly includes a filter plate 160 having a filter hole 160a. The filter plate 160 separates the sub-cavity into the accommodating chamber 30e and the mixing chamber 30d. The filter hole 160a connects the accommodating chamber 30e and the mixing chamber 30d. The discharge port 140b is connected to the accommodating chamber 30e. For example, the discharge port 140b can be located in the accommodating chamber 30e. The accommodating chamber 30e and the mixing chamber 30d share the filter plate 160.

[0158] In this embodiment, the fluid discharged from outlet 140b sequentially flows through the receiving chamber 30e, filter holes 160a, and mixing chamber 30d. That is, the fluid discharged from outlet 140b first enters the receiving chamber 30e, is filtered by filter plate 160, and then enters the mixing chamber 30d through filter holes 160a. For example, when washing powder is used, the water impacts and dissolves the washing powder in detergent dispensing chamber 140a. However, since the water impacts the washing powder in detergent dispensing chamber 140a for a short period of time, insufficient dissolution of the washing powder can occur. Filter plate 160 can temporarily retain particles larger than or equal to the pore size of filter holes 160a in receiving chamber 30e, while particles smaller than the pore size of filter holes 160a can enter the mixing chamber 30d and then enter the laundry processing chamber through first outlet 140b. During the washing process, the detergent mixture from the washing dispensing chamber repeatedly rinses the washing powder retained in receiving chamber 30e, allowing the washing powder to dissolve again before entering the mixing chamber 30d. This design makes the washing powder dissolve better, and the particles of washing powder entering the clothing processing chamber are relatively small, thereby improving the cleaning effect.

[0159] It is understood that the detergent dispensing chamber 140a, the accommodating chamber 30e, the mixing chamber 30d, the liquid outlet passage 130b, and the mixing space 20a are all part of the first waterway 40A. The liquid flow passage 130a is part of the second waterway 50A. The first waterway 40A may include a fluid path between the water inlet valve 90 and the liquid outlet 20ab. The second waterway 50A may include a fluid path between the water inlet valve 90 and the second water outlet 50Aa.

[0160] In one embodiment, please refer to Figures 3 to 9 , the accommodating chamber 30e is located above the mixing chamber 30d. That is to say, the thickness direction of the filter plate 160 can be consistent with the up and down direction. The filter plate 160 can temporarily retain particles that are greater than or equal to the aperture of the filter hole 160a on the upper surface of the filter plate 160, while particles that are smaller than the aperture of the filter hole 160a can enter the mixing chamber 30d below and then enter the clothing processing chamber through the first outlet 140b. 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 dissolves again and then enters the mixing chamber 30d. The washing powder dissolves better, and the particles of the washing powder entering the clothing processing chamber are relatively small, which improves the cleaning effect.

[0161] For some examples, see Figures 3 to 12The detergent dispensing device includes a first pipe 41, a second pipe 42, and a detergent box 30 having a first drain port 30b. One end of the first pipe 41 is connected to a water source, and the other end of the first pipe 41 is connected to the water inlet of the detergent box 30, for introducing water into the detergent box 30. One end of the second pipe 42 is connected to the first drain port 30b, and the other end of the second pipe 42 is connected to the liquid outlet channel 130b.

[0162] In this embodiment, the space within the first conduit 41, the space within the second conduit 42, and at least a portion of the space within the detergent box 30 collectively constitute at least a portion of the first water path 40A. The water introduced by the first conduit 41 can flush the detergent delivery chamber 140a, allowing the detergent mixed solution in the detergent delivery chamber 140a to enter the mixing chamber 30d. The detergent mixed solution in the mixing chamber 30d then flows through the first drain port 30b and the second conduit 42 into the liquid outlet channel 130b.

[0163] For some examples, see Figures 3 to 12 The detergent dispensing device includes a third pipe 50. One end of the third pipe 50 is connected to a water source and is connected to the liquid flow channel 130a to guide water from the water source to the liquid flow channel 130a. In this embodiment, the space within the third pipe 50 defines a portion of the second water channel 50A.

[0164] It should be noted that the first pipeline 41 can be a complete pipe or can be formed by connecting multiple pipe sections, which is not limited here.

[0165] The second pipeline 42 can be a complete pipe or can be formed by connecting multiple pipe sections, which is not limited here.

[0166] The third pipeline 50 can be a complete pipe or can be formed by connecting multiple pipe sections, which is not limited here.

[0167] Exemplarily, the third pipeline 50 can be entirely arranged on the outside of the detergent box 30; or, a portion of the third pipeline 50 is integrated into the box body of the detergent box 30, that is, part of the box body of the detergent box 30 constitutes a portion of the third pipeline 50; or, the third pipeline 50 is a pipeline structure that runs through the detergent box 30.

[0168] In some embodiments, the door seal 60 has an installation opening, and the liquid outlet 20ab passes through the installation opening of the door seal 60 and extends radially inwardly of the door seal 60. For example, the spray head 130 is disposed through the door seal 60, and the sidewall of the spray head 130 formed with the liquid outlet 20ab can extend radially inwardly of the door seal 60. This facilitates the liquid outlet 20ab to directly spray the detergent mixture into the laundry treatment chamber.

[0169] In some embodiments, the liquid outlet 20ab extends radially inwardly of the door seal 60 and is inclined to discharge water toward the lower rear of the clothing treatment chamber, so that the sprayed mixed liquid covers a large area of ​​the clothing in the clothing treatment chamber.

[0170] For example, see Figures 3 to 12 Sprinkler 130 also includes a connector pipe 133 connected to housing 132. Connector pipe 133 communicates with the end of liquid outlet channel 130b distal from first water outlet end 40Aa. The space within connector pipe 133 forms part of first waterway 40A. Connector pipe 133 connects to second pipe 42. Second pipe 42 delivers fluid to sprinkler 130 via connector pipe 133.

[0171] For example, part of the cannula 131 is located in the mixing space 20a, and the other part of the cannula 131 protrudes from the housing 132. The part of the cannula 131 protruding from the housing 132 can be used to connect to the third pipeline 50. The water in the third pipeline 50 can be introduced into the mixing space 20a through the cannula 131.

[0172] The nozzle 130 may be an integrally formed structure, that is, the housing 132, the insert 131 and the connector 133 are integrally formed, for example, by injection molding or other processes. Of course, the nozzle 130 may also be a split component that is assembled after processing.

[0173] In some embodiments, the outer barrel 11 has a water inlet, and the second drain port 30a is connected to the water inlet, which is used to guide the detergent mixed solution in the overflow chamber 30c to the outer barrel 11 and then enter the inner barrel through the flow hole of the inner barrel, which can assist water inlet.

[0174] For example, Figure 1 As shown, the clothes treating apparatus further includes a water outlet pipe 70 , which connects the second drain port 30 a and the water inlet.
