In the embodiments of this application, the orientations or positional relationships of "up," "down," "front," "back," "left," and "right" are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientational terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In addition, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the embodiments of this application, "multiple" means that the quantity includes two or more. "At least two" means that the quantity includes two or more.

[0039] The clothing processing device provided in this application embodiment has no limited functionality. For example, in addition to washing, the clothing processing device may also have a drying function. The drying function can be used to dry clothing.

[0040] Clothing processing equipment can be drum-type clothing processing equipment, such as drum washing machines or drum washer-dryer combos.

[0041] The garment processing equipment includes a garment processing chamber for holding garments.

[0042] The garment processing chamber of a drum-type garment processing device rotates about an axis that extends horizontally or obliquely. An oblique axis means that the axis of the garment processing chamber is oblique to the horizontal direction.

[0043] Please see Figure 1 The garment processing equipment may include a drum assembly 10, the axis of which may extend horizontally or obliquely. The internal space of the drum assembly 10 may be at least a portion of the garment processing chamber.

[0044] In some embodiments, please refer to Figure 1 and Figure 2 The garment handling equipment may include a door seal ring 60. The axis of the tubular assembly 10 extends in a horizontal direction or in an inclined direction, and the door seal ring 60 may be disposed at the front end of the tubular assembly 10.

[0045] In some embodiments, the drum assembly 10 includes a rotatable inner drum with an access port. The access port can face forward, and the inner drum can be used to hold loads such as clothing. The user inserts or removes clothing into or from the inner drum from the front through the space enclosed by the door seal ring 60 and the access port. The inner drum can rotate, for example, clothing, water, and detergent rotate with the inner drum, thus the clothing continuously changes its position within the inner drum, and the fluids such as water and detergent change their flow direction with the inner drum.

[0046] In some embodiments, the inner cylinder may be generally hollow and cylindrical.

[0047] In some embodiments, please refer to Figure 1 The drum assembly 10 includes an outer drum 11, and an inner drum can be disposed within the outer drum 11. The outer drum 11 is used to hold water for washing clothes, and the inner drum is used to hold clothes.

[0048] In this embodiment, water is contained in the outer tub 11, and the inner tub can also be referred to as a perforated inner tub. The space inside the inner tub is at least a portion of the garment processing chamber. Fluid can flow through the flow holes in the inner tub between the space between the outer tub 11 and the inner tub, and between the space inside the inner tub.

[0049] In some embodiments, please refer to Figure 1 The outer barrel 11 can be roughly hollow and cylindrical.

[0050] In some embodiments, the inner cylinder holds water on its own and can also be referred to as a non-perforated inner cylinder. An outer cylinder 11 may or may not be provided on the outside of the inner cylinder.

[0051] It is understood that in some embodiments, the cylinder assembly 10 may only have an inner cylinder and not the aforementioned outer cylinder 11. In this embodiment, the inner cylinder is a non-perforated inner cylinder that can hold water. The inner cylinder can be a single-cylinder structure. In other words, the clothing processing device has only one cylinder, the inner cylinder.

[0052] In some embodiments, the garment handling device includes a housing, a tubular assembly 10 disposed within the housing, and the housing having an opening communicating with the internal space of the tubular assembly 10.

[0053] In some embodiments, the housing may be approximately hexahedral in shape, such as a cube or a cuboid.

[0054] In some embodiments, the garment processing device includes a door for selectively opening or closing the opening of the housing, the axis of the cylinder assembly 10 extends in a horizontal or inclined direction, and a door seal ring 60 can be used to seal the gap between the cylinder assembly 10 and the opening of the housing. The communicating space formed inside the door, the door seal ring 60 and the cylinder assembly 10 constitutes a garment processing chamber.

[0055] This application provides a detergent dispensing device for use in clothing processing equipment.

[0056] Please see Figures 10 to 12 The detergent dispensing device includes a first water path 40A and a liquid flow channel 130a. The side wall of the first water path 40A is opened to form a liquid outlet 20ab. The first water path 40A includes a mixing space 20a. The liquid flow channel 130a has a second water outlet 50Aa. At least one of the first water path 40A and the liquid flow channel 130a conveys a detergent mixture solution. The second water outlet 50Aa is connected to the liquid outlet 20ab through the mixing space 20a.

[0057] The second water outlet 50Aa is connected to the liquid outlet 20ab through the mixing space 20a. That is to say, 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 path 40A and the liquid flow channel 130a conveys a detergent mixture solution. For example, the first water path 40A conveys a detergent mixture solution, and the liquid flow channel 130a conveys other fluids; or, for another example, the liquid flow channel 130a conveys a detergent mixture solution, and the first water path 40A conveys other fluids; or, for yet another example, both the first water path 40A and the liquid flow channel 130a convey a detergent mixture solution.

[0059] Other fluids include, but are not limited to, aqueous solutions or solutions with added care ingredients. Aqueous solutions include, but are not limited to, tap water or recycled water from a water source.

[0060] It is understandable that both the first water channel 40A and the liquid flow channel 130a are used to transport fluids, and both detergent mixture and water are fluids.

[0061] The fluid within the mixing space 20a includes, but is not limited to, a detergent mixture of detergent and water. The outlet 20ab is used to discharge the fluid from the mixing space 20a.

[0062] The detergent dispensing device provided in this application embodiment has an opening in the side wall of the first water channel 40A to form a liquid outlet 20ab, which simplifies the dispensing structure. The second water outlet 50Aa is connected to the liquid outlet 20ab through a mixing space 20a. The fluid discharged from the second water outlet 50Aa enters the mixing space 20a to merge and mix with the fluid in the first water channel 40A, thereby improving the mixing effect and making the detergent, such as laundry powder, dissolve more fully.

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

[0064] In some embodiments, please refer to Figures 10 to 12 The side wall 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 same side as the first water outlet end 40Aa of the liquid outlet channel 130b. That is, 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 outlet 40Aa and the second outlet 50Aa outputs a detergent mixture solution. For example, both the first outlet 40Aa and the second outlet 50Aa output detergent mixture solutions. Another example is that the first outlet 40Aa outputs a detergent mixture solution, while the second outlet 50Aa outputs other fluids. Yet another example is that the second outlet 50Aa outputs a detergent mixture solution, while the first outlet 40Aa outputs other fluids.

[0066] It should be noted that the detergent mixture mentioned in this application is merely for ease of description and refers to a mixture containing dissolved detergent. Its mass percentage concentration is not limited, and the detergent mixture does not necessarily mean that the detergent is completely dissolved. In some embodiments, the detergent mixture may be undiluted detergent added by the user. In other embodiments, the detergent mixture may be a mixture of detergent and water from a water source.

[0067] The function of detergent is not limited to cleaning, softening and / or fragrance.

[0068] The type of detergent is not limited, and detergents include, but are not limited to, cleaning agents, fabric softeners, and / or fragrances, etc.

[0069] The form of detergent is not limited; it can be powdered laundry detergent or liquid laundry detergent that can be dispensed.

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

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

[0072] This application provides a clothing processing device, which includes a detergent dispensing device and a clothing processing chamber as described in any embodiment of this application. A liquid outlet 20ab delivers fluid to the clothing processing chamber. In other words, the fluid delivered by the first water path 40A and the liquid flow channel 130a ultimately enters the clothing processing chamber for processing the clothing.

[0073] In one embodiment, please refer to Figure 12 The liquid outlet channel 130b includes an expansion section, with the largest flow area at the first outlet end 40Aa. This means that the fluid in the liquid outlet channel 130b is ultimately ejected from the expansion section into the mixing space 20a. The expansion section reduces head loss and promotes rapid discharge of the fluid from the liquid outlet channel 130b.

[0074] It should be noted that the flow cross-section is a section taken perpendicular to the streamline cluster. When the streamline clusters are not parallel to each other, the flow cross-section is a curved surface; when the streamline clusters are parallel straight lines, the flow cross-section is a plane. 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 the direction away from the first outlet 40Aa to the direction closer to the first outlet 40Aa. Under the guidance of the expansion section, the fluid tends to concentrate towards the mixing space 20a, so that it fills the mixing space 20a as much as possible and mixes thoroughly with the fluid discharged from the second outlet 50Aa.

[0076] In one embodiment, please refer to Figures 10 to 12 The area of ​​the first water outlet 40Aa is larger than the area of ​​the second water outlet 50Aa, and the area of ​​the first water outlet 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. The mixed fluid is discharged from the liquid outlet 20ab and enters the clothing processing chamber to participate in clothing processing. This design can effectively suppress the backflow phenomenon caused by the excessive flow difference between the first water outlet 40Aa and the second water outlet 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 outlet end 40Aa refers to the flow area of ​​the first outlet end 40Aa. The area of ​​the second outlet end 50Aa refers to the flow area of ​​the second outlet end 50Aa. 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 fluid flow channel 130a is provided with a pressurizing structure 120, which 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 fluid flow channel 130a.

[0079] In this embodiment, the pressurizing structure 120 accelerates the fluid in the liquid flow channel 130a. There is a velocity 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 velocity at the second outlet 50Aa is greater than the velocity at the first outlet 40Aa. The two fluids entering the mixing space 20a have different velocities, one fast and one slow. The faster fluid can impact and disturb the slower fluid, allowing the detergent to mix better 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 narrowing section 22, which increases the flow velocity at the second outlet 50Aa. The narrowing section 22 refers to the section where the fluid's flow area decreases along the flow direction. By limiting the fluid's flow area, the narrowing section 22 increases the fluid's impact force, resulting in a better mixing effect. Simultaneously, the narrowing section 22 allows the second outlet 50Aa to have a higher jet velocity, generating a significant negative pressure in a relatively large surrounding area. This negative pressure draws the fluid from the first outlet 40Aa into the second outlet 50Aa, mixing it with the fluid discharged from the second outlet 50Aa, thus enhancing the mixing effect.

[0081] In some embodiments, the pressurization structure 120 includes a powered pressurization mechanism. A powered pressurization mechanism is a mechanism that uses a power source to increase fluid pressure and thus increase flow velocity. The power source includes, but is not limited to, electrical energy or other energy sources. The powered pressurization mechanism can actively increase fluid flow velocity, which, compared to the passive increase in fluid flow velocity by the narrowed section 22, offers a higher degree of automation.

[0082] The type of power pressurization mechanism is not limited. For example, power pressurization mechanisms include, but are not limited to, water pumps, peristaltic pumps, etc.

[0083] In some embodiments, the end of the pressurizing structure 120 forms a second water outlet 50Aa. That is, the fluid in the second water passage 50A is ejected directly from the end of the pressurizing structure 120, for example, the narrowed section 22.

[0084] In some embodiments, please refer to Figures 10 to 12 The end of the pressurization structure 120 is connected to a constant diameter section 23 and / or an enlarged diameter section, which forms a second outlet end 50Aa.

[0085] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23, which forms a second water outlet 50Aa.

[0086] For example, the end of the pressurization structure 120 is connected to an expansion section, which forms a second water outlet 50Aa.

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

[0088] The constant diameter section 23 refers to the section where the flow area of ​​the fluid remains basically unchanged along the flow direction.

[0089] An expansion section refers to a section where the flow area of ​​the fluid increases along the flow direction.

[0090] In this embodiment, the fluid in the liquid flow channel 130a is directly ejected from the constant diameter section 23 and / or the expanding diameter section into the mixing space 20a. After being accelerated by the pressurization structure 120, the fluid flows through the constant diameter section 23 and / or the expanding diameter section, and the fluid can flow out into the mixing space 20a in a conical divergence at a relatively fast speed.

[0091] In some embodiments, the extension length of the constant diameter section 23 along the second water passage 50A is less than or equal to the extension length of the narrow diameter section 22 along the second water passage 50A. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the constant diameter section 23 can reduce the loss of impact force after the fluid flows out of the narrow diameter section 22.

[0092] In some embodiments, the extension length of the expanding section along the second water passage 50A is less than or equal to the extension length of the narrowing section 22 along the second water passage 50A. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the expanding section can reduce the loss of impact force after the fluid flows out of the narrowing section 22.

[0093] In one embodiment, please refer to Figures 10 to 12 The end of the pressurizing structure 120 extends into the mixing space 20a. This extension increases the speed of the fluid entering the mixing space 20a. The increased speed of the fluid, after being accelerated by the pressurizing structure 120, allows it to enter the mixing space 20a through its end. The increased impact force of the accelerated fluid better agitates the fluid within the mixing space 20a, improving the mixing effect and increasing the washing ratio.

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

[0095] The aforementioned circumferential velocity component refers to the fluid in the flow channel 130a after passing through the turbulent structure 21, whose velocity component in the circumferential direction of the flow channel 130a is not zero, and the circumferential direction of the flow channel 130a surrounds the extension direction of the flow channel 130a.

[0096] After passing through the turbulent structure 21, the fluid in the liquid flow channel 130a generates a composite motion in multiple directions, including the circumferential direction and the forward direction, thereby better mixing with the fluid in the mixing space 20a and improving the mixing efficiency; it also enables the fluid ejected from the outlet 20ab to spread out in a roughly cone shape, with a wider radiation range and better visual effect.

[0097] Understandably, the turbulent structure 21 can also increase the fluid velocity by limiting the flow area of ​​the liquid flow channel 130a in which it is located. In this way, the velocity difference between the two fluid streams entering the mixing space 20a is further increased, which further promotes the dissolution of detergent.

[0098] In one embodiment, please refer to Figures 10 to 12 The turbulent structure 21 includes one or more helical blades, which guide the helical motion of the fluid. For example, the helical blades guide the helical motion of the fluid in the flow channel 130a. A helical blade is a blade with a helical shape, extending in the helical direction. After passing through the helical blades, the fluid exhibits a helical motion with a circumferential velocity component. The helical blade structure is simple, has a good turbulence effect on the fluid, and low resistance, reducing energy loss as the fluid passes through.

[0099] For example, the turbulent structure 21 includes one or more helical blades that divide at least a portion of the length of the fluid flow channel 130a into multiple sub-channels.

[0100] The term "multiple" refers to the number of helical blades, which can be two, three, or more, meaning the number of helical heads is not less than two, and does not limit the number of helical turns.

[0101] In some embodiments, please refer to Figures 10 to 12 The outer edge of the helical blade along the helical direction is connected to the inner wall of the liquid flow channel 130a, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the liquid flow channel 130a. That is, there is a gap between the inner edge of the helical blade and the inner wall of the liquid flow channel 130a, so the inner wall of the liquid flow channel 130a provides connection support for the helical blade.

[0102] In one embodiment, please refer to Figures 10 to 12 The pressurization structure 120 is located downstream of the turbulence structure 21. After passing through the turbulence structure 21 and the pressurization structure 120 (e.g., the narrowing section 22), the fluid is ejected into the mixing space 20a with a cone shape.

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

[0104] In this embodiment, the liquid outlet channel 130b delivers a detergent mixture solution, such as a laundry detergent mixture solution or a laundry powder mixture solution, especially a laundry powder mixture solution. Since laundry powder is a powdered detergent, it is more prone to clogging and residue than laundry detergent. Therefore, while the liquid outlet channel 130b delivers the detergent mixture solution, the pressurizing structure 120 and / or the turbulent flow structure 21 are disposed in the liquid flow channel 130a, which is used to deliver water from a water source. This arrangement, to a certain extent, prevents the pressurizing structure 120 and / or the turbulent flow structure 21 from contacting the laundry powder.

[0105] In one embodiment, please refer to Figures 10 to 12 The detergent dispensing device includes a nozzle 130, which has a liquid outlet channel 130b, a liquid flow channel 130a, and a mixing space 20a. The liquid outlet 20ab penetrates 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 out through the liquid outlet 20ab of the nozzle 130 into the garment processing chamber. The fact that at least a portion of the liquid flow channel 130a extends into the mixing space 20a allows for better agitation of the fluid within the mixing space 20a, thus improving the mixing effect.

[0106] In one embodiment, please refer to Figures 10 to 12 The portion of the liquid flow channel 130a within the mixing space 20a extends along a first direction, while the outlet channel 130b is located on one side of the liquid flow channel 130a along a second direction, with the first and second directions intersecting. Thus, 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 outlet channel 130b enters the mixing space 20a approximately along the second direction. The intersecting flow directions of the two fluids enhance the impact effect. When the flow velocity of the fluid discharged from the liquid flow channel 130a is greater than that of the fluid discharged from the outlet channel 130b, a negative pressure is generated near the second outlet end 50Aa. This negative pressure draws the fluid from the first outlet end 40Aa, causing it to change direction and flow towards the first direction, generating foam in the fluid and enhancing the mixing uniformity of detergents such as laundry powder.

[0107] For example, the pressurization structure 120 may be formed in the portion of the liquid flow channel 130a located within the mixing space 20a. The turbulence structure 21 may be formed in the 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 tube 131. The housing 132 forms a liquid outlet channel 130b, a mixing space 20a, and a liquid outlet 20ab. At least a portion of the tube 131 is inserted into the mixing space 20a, and the tube 131 forms a liquid flow channel 130a. That is, the liquid outlet 20ab penetrates the outer surface of the side wall of the housing 132, and a second water outlet 50Aa is formed in the tube 131. For example, the port of the tube 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 a one-piece molded structure. For example, the nozzle 130 may be a one-piece injection molded structure.

[0110] As an example, in one embodiment, please refer to Figures 10 to 12 The port of the insertion tube 131 facing the first direction is the second water outlet 50Aa, and the first water outlet 40Aa is formed on the side wall 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, and the fluid discharged from the second water outlet 50Aa flows generally in the second direction, and the two fluids converge 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 its sidewall along the first direction. For example, the liquid outlet 20ab is formed on the sidewall of the housing 132 along the first direction. Fluid within the mixing space 20a is ejected from the nozzle 130 through the liquid outlet 20ab.

[0112] In one embodiment, please refer to Figure 2 The nozzle 130 is located on the door seal ring 60. The door seal ring 60 not only provides an installation position for the nozzle 130, but also allows the detergent mixture sprayed by the nozzle 130 to be closer to the garment processing chamber.

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

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

[0115] It should be noted that the extension direction of the axis of the door seal ring 60 is consistent with the extension direction of the axis of the cylinder assembly 10. The axis of the door seal ring 60 can extend horizontally or inclined.

[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 and an outlet 20ab penetrating the outer surface of the sidewall of the nozzle 130. The nozzle 130 forms the mixing space 20a, meaning that the fluid in the outlet channel 130b and the fluid in the flow channel 130a both converge and mix within the nozzle 130. The outlet 20ab penetrates the outer surface of the sidewall of the nozzle 130, and the fluid within the nozzle 130 is ejected through the outlet 20ab. Thus, the fluids from both water paths are sprayed through the nozzle 130 into the garment processing chamber.

[0117] In one embodiment, please refer to Figures 10 to 12 Please see Figures 10 to 12 The nozzle 130 forms an outlet 20ab along the side wall in the first direction, and the first water outlet 40Aa is formed on the side wall of the mixing space 20a along the second direction, where the first and second directions 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 40Aa is formed on the side wall of the mixing space 20a along the second direction. That is, the fluid discharged from the first water outlet 40Aa enters the mixing space 20a in the second direction and mixes with the fluid from the second water outlet 50Aa. Then, it is sprayed out through the liquid outlet 20ab in the first direction. This can appropriately increase the flow path of the fluid discharged from the first water outlet 40Aa and improve the mixing effect.

[0119] In one embodiment, the outlet 20ab is directly connected to the garment processing chamber. Direct connection means that the outlet 20ab opens into the garment processing chamber, and fluid from the outlet 20ab directly enters the garment processing chamber. There is no intermediate channel, such as a transfer pipe or other fluid-passing component, between the outlet 20ab and the garment processing chamber. The fluid at the outlet 20ab does not need to be guided by an intermediate channel; instead, it is directly introduced into the garment processing chamber under its own gravity and flow velocity.

[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. This eliminates the need for a transfer channel between the liquid outlet 20ab and the clothing processing chamber, saving on transfer channels and reducing production costs. Fluids such as detergent mixtures can directly enter the clothing processing chamber from the liquid outlet 20ab and act directly on the clothing.

[0121] It is understandable that the outlet 20ab can penetrate the outer surface of the solid structure in which it is located.

[0122] In one embodiment, the outlet 20ab can also be connected to a transfer channel. That is, the outer surface of the solid structure containing the outlet 20ab is connected to the transfer channel, and the fluid from the outlet 20ab flows through the transfer channel before entering the garment processing chamber. The flow direction and / or shape of the fluid can be changed by the transfer channel, allowing fluid to be sprayed onto garments at specific locations and / or sprayed in a specific shape.

[0123] In one embodiment, please refer to Figure 2 The liquid outlet 20ab is located inside the garment processing chamber. For example, the liquid outlet 20ab extends radially inward from the door seal ring 60. This brings the liquid outlet 20ab closer to the garments inside the processing chamber, reducing the likelihood 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 50Aa faces the liquid outlet 20ab. The second water outlet 50Aa facing the liquid outlet 20ab means that the orientation of the second water outlet 50Aa is the same as the orientation of the liquid outlet 20ab. For example, the second water outlet 50Aa and the liquid outlet 20ab both face the same side of the first direction.

[0125] In this embodiment, the second water outlet 50Aa faces the liquid outlet 20ab, and the liquid outlet 20ab is downstream of the flow direction of the fluid discharged from the second water outlet 50Aa, so that the flow discharged from the second water outlet 50Aa flows toward the location of the liquid outlet 20ab, and the fluid from the second water outlet 50Aa can flow to the liquid outlet 20ab and be discharged quickly with minimal change in flow direction.

[0126] In one embodiment, please refer to Figures 10 to 12 Using the plane containing the outlet 20ab as the projection plane, the projection of the second outlet 50Aa onto the projection plane lies within the projection range of the outlet 20ab. For example, the flow area of ​​the outlet 20ab can be larger than the flow area of ​​the second outlet 50Aa. This avoids misalignment between the second outlet 50Aa and the outlet 20ab, which could cause a change 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 outlet 20ab and the pressurizing structure 120. With this design, the fluid path between the turbulent structure 21 and the pressurizing structure 120 is longer than the fluid path between the pressurizing structure 120 and the outlet 20ab. This allows the fluid to be effectively accelerated by the turbulent structure 21 and the pressurizing structure 120, and to be promptly discharged from the mixing space 20a, 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 in the horizontal plane intersect. That is, 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 outlet end 40Aa refers to the straight line passing through the center point of the flow section of the first outlet end 40Aa. The axis of the second outlet end 50Aa refers to the straight line passing through the center point of the flow section of the second outlet end 50Aa.

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

[0131] In some embodiments, please refer to Figures 3 to 12 The detergent dispensing device includes a first water path 40A and a second water path 50A, with the liquid outlet channel 130b being a part of the first water path 40A. The liquid flow channel 130a is a part of the second water path 50A, and the second water outlet 50Aa is the water outlet of the second water path 50A.

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

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

[0134] In some embodiments, the inlet of the first water channel 40A can be connected to a water source, and the inlet of the second water channel 50A can be connected to a water source.

[0135] It should be noted that the water source in this embodiment refers to the water source that supplies water flow 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 garment processing equipment includes a water inlet valve 90, which is connected to a water source such as a tap water pipe. The first water path 40A and the second water path 50A can be connected to different water inlet valves 90, or they can be connected to the same water inlet valve 90; this is not limited here. As an optional embodiment, the garment processing equipment includes a circulation pump, with one of the first water path 40A and the second water path 50A connected to the water inlet valve 90, and the other connected to the circulation pump of the garment processing equipment.

[0137] In some embodiments, the inlet valve 90 has at least two water outlets, with the first water path 40A and the second water path 50A each connected to one of the water outlets. Water is supplied to the garment processing equipment through the inlet valve 90. The first water path 40A and the second water path 50A are each connected to one water outlet, and the flow rates at the different water outlets can be different, thus increasing the velocity difference between the fluids in the first water path 40A and the second water path 50A.

[0138] In some embodiments, please refer to Figures 3 to 9 The inlet valve 90 has a first outlet 90a, and both the first water path 40A and the second water path 50A are connected to the first outlet 90a. Water is supplied to the laundry processing equipment through the inlet valve 90. The first water path 40A and the second water path 50A are both connected to the first outlet 90a of the inlet valve 90, which facilitates the installation of the first water path 40A and the second water path 50A, simplifies the setup of the inlet valve 90, and saves costs.

[0139] In some embodiments, please refer to Figures 3 to 12 The detergent dispensing device includes a detergent supply component, which includes a detergent passage and a first drain outlet 30b. The detergent passage is connected to the atmospheric environment. The first water path 40A connects the water source, the detergent passage, the first drain outlet 30b, and the liquid outlet 20ab. The second water path 50A connects the water source and the mixing space 20a.

[0140] The detergent pathway refers to the flow path of detergent within the detergent supply component.

[0141] The first water passage 40A connects a water source, a detergent passage, a first drain outlet 30b, and a liquid outlet 20ab. That is, the detergent passage, the first drain outlet 30b, and the mixing space 20a constitute at least a part of the first water passage 40A. Fluid from the water source flows through the detergent passage and the first drain outlet 30b. For example, in the first water passage 40A, fluid from the water source flows through the detergent container and mixes with the detergent to form a detergent mixture solution. The detergent mixture solution flows to the first drain outlet 30b, is discharged through the first drain outlet 30b, and flows into the mixing space 20a.

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

[0143] In this embodiment, the detergent passage is connected to the atmospheric environment to form a pressure relief space. The initial water pressure of the fluid in the first water passage 40A at any cross-section of the end of the first water passage 40A connected to the water source is the initial water pressure. When the fluid in the first water passage 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 passage 40A to drop, i.e., pressure relief occurs. The depressurized fluid flows from the first drain outlet 30b to the inlet end of the mixing space 20a, so that the water pressure of the fluid flowing through the first water passage 40A at any cross-section of the inlet end of the mixing space 20a is less than the initial water pressure at any cross-section of the end of the first water passage 40A connected to the water source. In other words, the fluid from the water source enters the first water passage 40A at a relatively high pressure, undergoes pressure relief in the detergent passage, and makes the water pressure at the end of the first water passage 40A less than the water pressure at its inlet end.

[0144] In some embodiments, please refer to Figures 3 to 12 The detergent passage includes a mixing chamber 30d, the wall of which forms a first drain outlet 30b. The detergent supply assembly includes a second drain outlet 30a and an overflow chamber 30c. The overflow chamber 30c is used to collect the detergent mixture overflowing from the detergent passage, and the second drain outlet 30a is used to discharge the detergent mixture from the overflow chamber 30c. The first drain outlet 30b is used to discharge the detergent mixture from the mixing chamber 30d.

[0145] In this embodiment, when the liquid level in the detergent passage, such as the mixing chamber 30d, is not higher than the overflow level, the fluid in the mixing chamber 30d is discharged from the first drain port 30b and flows into the mixing space 20a. When the liquid level in the mixing chamber 30d is higher than the overflow level, the excess fluid overflows into the overflow chamber 30c and is discharged from the second drain port 30a. That is, the detergent mixture solution preferentially exits from the first drain port 30b, and the second drain port 30a serves as a safety protection function, enabling the timely discharge of excess fluid from the 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. This means that, given the same amount of water, the drainage volume of the second drain outlet 30a is greater than that of the first drain outlet 30b. Because the flow area of ​​the first drain outlet 30b is smaller, its outflow rate is relatively lower. The second drain outlet 30a and the overflow chamber 30c can promptly discharge the detergent mixture or water from the first water path 40A in case of overflow, reducing water flow blockage and providing safety protection.

[0147] In some embodiments, the detergent passage includes a detergent dispensing chamber 140a, which can be used to hold powdered laundry detergent. When the fluid from the first water passage 40A flows through the detergent dispensing chamber 140a, it initially dissolves the laundry detergent. Of course, the detergent dispensing chamber 140a can also be used to hold detergents with flow characteristics.

[0148] In some embodiments, please refer to Figures 3 to 12 The detergent supply assembly includes a detergent dispenser 30 and a dispenser box 140 disposed within the detergent dispenser 30. The dispenser box 140 has a detergent dispensing chamber 140a. The detergent dispenser 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 collect the detergent mixture flowing through the detergent dispensing chamber 140a. A first drain outlet 30b is disposed on the wall of the mixing chamber 30d. The overflow chamber 30c is used to collect the detergent mixture overflowing from the mixing chamber 30d. The detergent dispenser 30 has a second drain outlet 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 to the first drain outlet 30b under the action of water. For example, the upper side wall of the dispenser box 140 forms an inlet, which communicates with the detergent dispensing chamber 140a. When part of the detergent dispensing chamber 140a is outside the detergent box 30, the user can inject detergent into the detergent dispensing chamber 140a through the inlet; when the detergent dispensing chamber 140a is inside the detergent box 30, water can flow through the inlet to flush the detergent dispensing chamber 140a, thereby delivering the detergent mixture into the mixing chamber 30d.

[0150] The mixing chamber 30d is used to collect the fluid flowing through the detergent dispensing chamber 140a, and the first drain outlet 30b is located on the wall of the mixing chamber 30d. That is, the detergent mixture enters the mixing chamber 30d and is discharged from the first drain outlet 30b.

[0151] The first drain outlet 30b can be formed by the detergent box 30 itself, or by the 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 removably disposed within 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, allowing the user to dispense detergent into the detergent dispensing chamber 140a.

[0153] For example, when the dispenser box 140 is housed in the detergent box 30, the mixing chamber 30d is located below the dispenser box 140. The detergent mixture flows from the detergent dispensing 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 baffle 170, the detergent box 30 has a cavity, the baffle 170 extends upward along the wall of the cavity to divide the cavity into a sub-cavity and an overflow cavity 30c, at least a portion of the sub-cavity is a mixing cavity 30d, the sidewall of the mixing cavity 30d forms a first drain outlet 30b, and the sidewall of the overflow cavity 30c forms a second drain outlet 30a.

[0155] It is understandable that the top of the baffle 170 can be spaced apart 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 baffle 170, and the fluid in the mixing chamber 30d can overflow into the overflow chamber 30c through the gap between the baffle 170 and the upper surface of the cavity.

[0156] In this embodiment, the baffle 170 separates the sub-cavity and the overflow cavity 30c. The fluid level in the mixing cavity 30d is higher than the height of the baffle 170. The fluid in the mixing cavity 30d can overflow into the overflow cavity 30c through the gap between the baffle 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 with filter holes 160a, which divides the sub-cavity into a receiving cavity 30e and a mixing cavity 30d. The filter holes 160a connect the receiving cavity 30e and the mixing cavity 30d, and the outlet 140b communicates with the receiving cavity 30e. Exemplarily, the outlet 140b may be located within the receiving cavity 30e. The receiving cavity 30e and the mixing cavity 30d share the filter plate 160.

[0158] In this embodiment, the fluid discharged from outlet 140b flows sequentially through the receiving cavity 30e, the filter hole 160a, and the mixing cavity 30d. That is, the fluid discharged from outlet 140b first enters the receiving cavity 30e, is filtered by the filter plate 160, and then enters the mixing cavity 30d through the filter hole 160a. Taking laundry detergent as an example, the water flow impacts and dissolves the laundry detergent in the detergent dispensing cavity 140a. Because the water flow impacts the laundry detergent in the detergent dispensing cavity 140a for a relatively short time, insufficient dissolution of the laundry detergent is likely to occur. The filter plate 160 can temporarily retain particles larger than or equal to the pore size of the filter hole 160a in the receiving cavity 30e, while particles smaller than the pore size of the filter hole 160a can enter the mixing cavity 30d and then enter the clothing processing cavity through the first outlet 140b. During the washing process, the detergent mixture from the washing dispensing cavity can repeatedly rinse the laundry detergent retained in the receiving cavity 30e, allowing the laundry detergent to dissolve again before entering the mixing cavity 30d. This design allows for better dissolution of laundry detergent, resulting in smaller detergent particles entering the garment processing chamber and improved cleaning performance.

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

[0160] In one embodiment, please refer to Figures 3 to 9 The receiving cavity 30e is located above the mixing cavity 30d. That is, the thickness direction of the filter plate 160 can be aligned with the vertical direction. The filter plate 160 can temporarily retain particles larger than or equal to the pore size of the filter holes 160a on its upper surface, while particles smaller than the pore size of the filter holes 160a can enter the mixing cavity 30d below, and then enter the garment processing cavity through the first outlet 140b. During the washing process, the detergent mixture from the washing dispensing cavity can repeatedly rinse the detergent on the upper surface of the filter plate 160, causing the detergent to dissolve again before entering the mixing cavity 30d. This results in better detergent dissolution, and the detergent particles entering the garment processing cavity are relatively smaller, improving the cleaning effect.

[0161] In some embodiments, please refer to Figures 3 to 12The detergent dispensing device includes a first pipe 41, a second pipe 42, and a detergent dispenser 30 with a first drain outlet 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 dispenser 30 to guide water into the detergent dispenser 30. One end of the second pipe 42 is connected to the first drain outlet 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 pipe 41, the space within the second pipe 42, and at least a portion of the space in the detergent dispenser 30 together constitute at least a portion of the first water path 40A. The water flow introduced through the first pipe 41 can flush the detergent dispensing chamber 140a, allowing the detergent mixture in the detergent dispensing chamber 140a to enter the mixing chamber 30d. The detergent mixture in the mixing chamber 30d enters the liquid outlet channel 130b through the first drain outlet 30b and the second pipe 42.

[0163] In some embodiments, please refer to Figures 3 to 12 The detergent dispensing device includes a third pipe 50, one end of which is introduced into a water source. The third pipe 50 is connected to a liquid flow channel 130a to guide water from the water source into the liquid flow channel 130a. In this embodiment, the space within the third pipe 50 defines a portion of the second water path 50A.

[0164] It should be noted that the first pipeline 41 mentioned above can be a single complete pipe or it can be composed of multiple pipe segments connected together; there is no limitation on this.

[0165] The second pipe 42 mentioned above can be a single pipe or a combination of multiple pipe sections; there is no limitation on this.

[0166] The aforementioned third pipe 50 can be a single, complete pipe or composed of multiple pipe segments connected together; no restrictions are imposed here.

[0167] For example, the third pipe 50 may be integrally disposed outside the detergent box 30; or, a part of the third pipe 50 may be integrated into the box body of the detergent box 30, that is, a part of the box body of the detergent box 30 constitutes a part of the third pipe 50; or, the third pipe 50 may be a pipe-like structure that penetrates the detergent box 30.

[0168] In some embodiments, the door seal ring 60 has a mounting opening through which the liquid outlet 20ab extends radially inward. For example, a nozzle 130 is disposed within the door seal ring 60, and the sidewall of the nozzle 130 having the liquid outlet 20ab extends radially inward into the door seal ring 60. This facilitates the direct spraying of the detergent mixture into the garment processing chamber via the liquid outlet 20ab.

[0169] In some embodiments, the outlet 20ab extends radially inside the door seal ring 60, and the outlet 20ab is tilted towards the rear and lower part of the clothing processing chamber to facilitate the sprayed mixture to cover the clothing in the clothing processing chamber over a large area.

[0170] For example, please refer to Figures 3 to 12 The nozzle 130 also includes a connector pipe 133, which is connected to the housing 132 and communicates with the end of the liquid outlet channel 130b away from the first water outlet end 40Aa. The space inside the connector pipe 133 forms part of the first water passage 40A, and the connector pipe 133 can be used to connect to a second pipe 42. The second pipe 42 delivers fluid to the nozzle 130 via the connector pipe 133.

[0171] For example, a portion of the cannula 131 is located within the mixing space 20a, while another portion of the cannula 131 protrudes from the housing 132. The portion of the cannula 131 protruding from the housing 132 can be used to connect to a third conduit 50. Water from the third conduit 50 can be introduced into the mixing space 20a through the cannula 131.

[0172] The nozzle 130 can be a one-piece molded structure, meaning that the housing 132, the insert 131, and the connector tube 133 are molded as a single piece, for example, through injection molding or other processes. Of course, the nozzle 130 can also be a separate component, which is assembled after processing.
