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.
[0072] 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.
[0073] 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.
[0074] Clothing processing equipment can be either drum-type or pulsator-type, such as drum washing machines or pulsator washing machines.
[0075] The garment processing equipment includes a garment processing chamber for holding garments.
[0076] The garment processing chamber of a drum-type garment processing device rotates about an axis extending horizontally or obliquely. The garment processing chamber of a pulsator-type garment processing device rotates about an axis extending vertically.
[0077] The axis of inclination refers to the axis of the garment processing chamber being oblique to the horizontal direction.
[0078] Referring to Figure 1, the garment processing device may include a tubular assembly 10, the axis of which may extend vertically, horizontally, or obliquely. The internal space of the tubular assembly 10 may be at least a portion of the garment processing chamber.
[0079] In some embodiments, referring to Figures 1 and 2, the garment handling device may include a door seal ring 60. The axis of the drum assembly 10 extends horizontally or obliquely, and the door seal ring 60 may be disposed at the front end of the drum assembly 10. The garment handling device in this embodiment is also referred to as a drum-type garment handling device, such as a drum washing machine.
[0080] In some embodiments, referring to Figure 13, the garment processing device includes a worktable 80, the axis of which extends vertically from the drum assembly 10, and the worktable 80 may be disposed above the drum assembly 10. The worktable 80 constitutes the exterior surface of the garment processing device. The garment processing device in this embodiment is also referred to as a pulsator-type garment processing device, such as a pulsator washing machine.
[0081] Please refer to Figure 13. The workbench 80 has a clothing inlet 80a, which extends through two surfaces of the workbench 80 in the vertical direction and is connected to the clothing processing chamber.
[0082] In some embodiments, the drum assembly 10 includes a rotatable inner drum with a loading / unloading port. The loading / unloading port can face upwards or forwards. The inner drum can be used to hold loads such as clothing. The inner drum can rotate, for example, clothing, water, and detergent rotate with the inner drum, so that the clothing continuously changes its posture inside the inner drum, and the fluids such as water and detergent change their flow direction with the inner drum.
[0083] For pulsator-type garment handling equipment, the loading and unloading ports face upwards. Users can put or take out garments into or out of the inner drum from above through the garment loading port 80a and the loading and unloading port.
[0084] For drum-type garment handling equipment, the loading and unloading port faces forward. Users can put or take out clothes into or out of the inner drum from the front through the space enclosed by the door seal ring 60 and the loading and unloading port.
[0085] In some embodiments, the inner cylinder may be generally hollow and cylindrical.
[0086] In some embodiments, referring to Figure 1, the tub assembly 10 includes an outer tub 11, and an inner tub may be disposed within the outer tub 11. The outer tub 11 can be used to hold water for washing clothes, and the inner tub is used to hold clothes.
[0087] 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.
[0088] In some embodiments, referring to Figure 1, the outer barrel 11 may be generally hollow and cylindrical.
[0089] 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.
[0090] 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.
[0091] In some embodiments, the garment handling equipment includes a housing, with the cylindrical assembly 10 disposed within the housing.
[0092] In some embodiments, the housing may be approximately hexahedral in shape, such as a cube or a cuboid.
[0093] In some embodiments, the garment handling device includes a door for selectively opening or closing an opening in a housing. The housing has an opening communicating with the internal space of a drum assembly 10. The axis of the drum assembly 10 extends horizontally or obliquely. A door seal ring 60 can be used to seal the gap between the drum assembly 10 and the opening in the housing. The communicating space formed by the door, door seal ring 60, and the interior of the drum assembly 10 constitutes a garment handling cavity. That is, for a drum-type garment handling device, the door, door seal ring 60, and the communicating space formed inside the drum assembly 10 constitute a garment handling cavity.
[0094] In some embodiments, the garment handling device includes a door, the axis of the drum assembly 10 extends vertically, the worktable 80 can be disposed within the housing, and the door can selectively open or close the garment loading port 80a. That is, for a pulsator-type garment handling device, the space inside the inner drum can be at least a portion of the garment handling chamber, the worktable 80 and the housing together define a placement chamber, and the drum assembly 10 is located within the placement chamber.
[0095] The workbench 80 can be located on the upper part of the box. It can be understood that the projection plane is a plane perpendicular to the front-back direction, and the bisector is a straight line extending horizontally and bisecting the projection of the box. The upper part of the box can be the part of the box located above the bisector.
[0096] The workbench 80 can also be used to install components such as control panels, which can be used to control the operation of the clothing processing equipment.
[0097] Please refer to Figures 3 to 26. The garment processing device provided in this application embodiment includes a first water channel 40A and a second water channel 50A.
[0098] Please refer to Figures 12, 16, 19, and 26. The first water passage 40A has a first outlet end 40Aa, and the second water passage 50A has a second outlet end 50Aa. The first outlet end 40Aa refers to the point where the fluid in the first water passage 40A leaves the first water passage 40A. The second outlet end 50Aa refers to the point where the fluid in the second water passage 50A leaves the second water passage 50A.
[0099] 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. 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.
[0100] 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. The flow section is a section perpendicular to the streamline cluster. When the streamline clusters are not parallel to each other, the flow section is a curved surface; when the streamline clusters are parallel straight lines, the flow section is a plane.
[0101] At least one of the first water channel 40A and the second water channel 50A is used for circulating a detergent mixture solution. For example, both the first water channel 40A and the second water channel 50A are used for circulating a detergent mixture solution. As another example, the first water channel 40A is used for circulating a detergent mixture solution, and the second water channel 50A is used for circulating other fluids. Yet another example, the second water channel 50A is used for circulating a detergent mixture solution, and the first water channel 40A is used for circulating other fluids.
[0102] 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.
[0103] It is understandable that both the first water channel 40A and the second water channel 50A are used for circulating fluids, such as detergent mixtures and water.
[0104] 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.
[0105] The function of detergent is not limited. For example, the function of detergent includes, but is not limited to, cleaning, softening or fragrance.
[0106] The type of detergent is not limited, and detergents include, but are not limited to, cleaning agents, fabric softeners, and / or fragrances, etc.
[0107] The form of the cleaning agent is not limited; it can be powdered laundry detergent or liquid laundry detergent, etc.
[0108] The clothing treatment device provided in this application embodiment has a first water channel 40A and a second water channel 50A, both of which are circulated with fluid. The fluid circulating in the first water channel 40A is sprayed out approximately along the axis of the first water outlet 40Aa, and the fluid circulating in the second water channel 50A is sprayed out 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. In this way, the fluid sprayed from the first water outlet 40Aa and the fluid sprayed 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 foaming detergent to the clothes, thereby improving the cleaning effect.
[0109] It should be noted that in the embodiments of this application, the first water path 40A refers to the fluid flow path and does not specifically refer to a pipe structure. The second water path 50A refers to the fluid flow path and does not specifically refer to a pipe structure. The first water path 40A and the second water path 50A are two fluid flow paths with different directions. Please refer to Figures 28 to 35. The dashed lines with arrows in the figures indicate the direction of fluid flow.
[0110] 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.
[0111] 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.
[0112] In one embodiment, referring to Figures 3, 5, and 13, the garment processing device includes a water inlet valve 90 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 device 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 device.
[0113] 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 first water path 40A and the second water path 50A.
[0114] In one embodiment, the first water channel 40A is used to transport the detergent mixture solution, and the second water channel 50A is used to transport the liquid water.
[0115] In this embodiment, the first water path 40A conveys a detergent mixture, such as a laundry detergent mixture or a laundry powder mixture, especially a laundry powder mixture. Since laundry powder is a powdered detergent, it is more prone to clogging and residue than laundry detergent. Therefore, the second water path 50A is used to convey water from a water source. The pressure-boosting structure 120 and / or the turbulence structure 21 are installed in the second water path 50A to a certain extent to prevent the pressure-boosting structure 120 and the turbulence structure 21 from coming into contact with the laundry powder.
[0116] In one embodiment, referring to Figures 10 to 12, 16, 19, and 26, the garment processing device includes a mixing space 20a, with a first water outlet 40Aa and a second water outlet 50Aa both connected to the mixing space 20a. The fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa both enter the mixing space 20a and converge and mix, improving the mixing effect and allowing the detergent, such as laundry powder, to dissolve more fully. The fluid within the mixing space 20a includes, but is not limited to, a detergent mixture solution formed by mixing detergent and water.
[0117] It should be noted that the first water outlet 40Aa can also be understood as the boundary between the first water passage 40A and the mixing space 20a. The second water outlet 50Aa can also be understood as the boundary between the second water passage 50A and the mixing space 20a. The mixing space 20a can be a chamber formed in a solid structure.
[0118] It is understandable that both the first water channel 40A and the second water channel 50A are used to transport fluids, such as detergent mixtures and water.
[0119] In one embodiment, referring to Figure 27, the garment processing device includes a garment processing chamber 10a. The intersection of the axis of the first water outlet 40Aa and the axis of the second water outlet 50Aa is located within the garment processing chamber 10a. The fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa can converge within the garment processing chamber 10a. The garment processing device may not have a mixing space 20a; the fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa converge directly in the air, with the convergence area located within the garment processing chamber. In this way, the fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa promote the dissolution of detergent, such as laundry powder. Since the convergence area is located within the garment processing chamber, the distance from the convergence area to the garment being treated after the mixed fluid of the first water path 40A and the second water path 50A is shortened, reducing the degree of foam breaking and facilitating the application of foamy detergent to the garment, thereby improving the cleaning effect.
[0120] In one embodiment, referring to Figures 2, 10, 12, 15, and 26, the garment processing device includes a garment processing chamber, and a mixing space 20a has a liquid outlet 20ab, which is directly connected to the garment processing chamber. The liquid outlet 20ab is used to discharge fluid from the mixing space 20a.
[0121] It is understandable that the outlet 20ab can penetrate the outer surface of the solid structure in which it is located.
[0122] The direct connection between the outlet 20ab and the garment processing chamber means that the outlet 20ab opens into the garment processing chamber, and the fluid from the outlet 20ab directly enters the garment processing chamber. There is no intermediate channel, such as a transfer pipe or other component that allows fluid to flow, 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.
[0123] 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.
[0124] In one embodiment, the outlet 20ab can also be connected to a transfer channel. That is, the fluid from the outlet 20ab flows through the transfer channel before entering the garment processing chamber. The transfer channel can change the flow direction and / or shape of the fluid, allowing fluid to be sprayed onto garments at specific locations and / or sprayed in a specific shape.
[0125] In one embodiment, the liquid outlet 20ab is located inside the garment processing chamber. Exemplarily, 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 garment processing chamber, reducing the likelihood of defoaming in the fluid ejected from the liquid outlet 20ab.
[0126] In one embodiment, referring to Figures 12 and 26, 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, both the second water outlet 50Aa and the liquid outlet 20ab face the same side in the first direction. That is, the axis of the second water outlet 50Aa is parallel to or coincides with the axis of the liquid outlet 20ab.
[0127] The axis of outlet 20ab refers to the straight line passing through the center point of the flow section of outlet 20ab.
[0128] 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.
[0129] In one embodiment, referring to Figures 12, 19, and 26, the plane containing the outlet 20ab is used as the projection plane, and the projection of the second outlet 50Aa is located 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 outlet end of the liquid flow channel 130a and the outlet 20ab, which could cause a change in fluid flow direction.
[0130] In some embodiments, referring to Figures 12 and 20, the garment processing device includes a pressurization structure 120, and a first water channel 40A and / or a second water channel 50A are provided with the pressurization structure 120, which is used to increase the flow rate of the fluid.
[0131] For example, the first water passage 40A is equipped with a pressurization structure 120. As another example, the second water passage 50A is equipped with a pressurization structure 120. Yet another example, both the first water passage 40A and the second water passage 50A are equipped with a pressurization structure 120.
[0132] The pressurization structure 120 increases the speed of the fluid in the water channel. Taking the second water channel 50A as an example, the pressurization structure 120 increases the speed of the fluid in the second water channel 50A. The fluid transported by the first water channel 40A and the fluid transported by the second water channel 50A converge and mix in the mixing space 20a. The mixed fluid is discharged from the outlet 20ab and enters the clothing processing chamber to participate in clothing processing.
[0133] In this embodiment, there is a velocity difference between the fluid in the first water channel 40A and the fluid in the second water channel 50A. For example, the fluid in the second water channel 50A is accelerated by the pressurization 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, with the faster fluid impacting and disturbing the slower fluid, allowing the detergent to mix better when the two fluids meet, further promoting detergent dissolution. Alternatively, the fluids transported by the first water channel 40A and the second water channel 50A can meet in mid-air, with the velocity at the second outlet 50Aa greater than the velocity at the first outlet 40Aa, allowing the detergent to mix better when the two fluids meet, further promoting detergent dissolution. For ease of description, the embodiments of this application are mostly described with the second water channel 50A equipped with a pressurization structure 120 and a turbulence structure 21. When the first water channel 40A is equipped with a pressurization structure 120 and a turbulence structure 21, it has similar effects to the second water channel 50A being equipped with a pressurization structure 120 and a turbulence structure 21. For the sake of brevity, this application will not elaborate further.
[0134] In one embodiment, referring to Figures 12 and 20, the garment processing device includes a pressurizing structure 120. A second water channel 50A is provided with the pressurizing structure 120, which is used to increase the flow rate of the fluid in the second water channel 50A. For example, the pressurizing structure 120 is disposed in the liquid flow channel 130a of the second water channel 50A.
[0135] In this embodiment, the pressurizing structure 120 increases the fluid speed in the second water path 50A. The fluids transported by the first water path 40A and the second water path 50A converge and mix in the mixing space 20a. The mixed fluid is discharged from the outlet 20ab and enters the garment processing chamber to participate in garment processing. There is a velocity difference between the fluids in the first water path 40A and the second water path 50A. For example, the fluid in the second water path 50A is accelerated by the pressurizing structure 120, and the velocity at the second outlet 50Aa is greater than that at the first outlet 40Aa. The two fluids entering the mixing space 20a have different velocities, with the faster one impacting and disturbing the slower one. This allows the detergent to mix better when the two fluids converge, further promoting detergent dissolution. Of course, the fluids transported by the first water channel 40A and the fluids transported by the second water channel 50A can also meet in the air. The flow rate at the second water outlet 50Aa is greater than the flow rate at the first water outlet 40Aa, which allows the detergent to mix better when the two fluids meet, further promoting the dissolution of the detergent.
[0136] In one embodiment, referring to Figures 12 and 20, the pressurizing structure 120 includes a narrowed section 22, which increases the flow velocity at the second outlet 50Aa. The narrowed section 22 refers to the section where the flow area of the fluid decreases along the flow direction. By limiting the flow area, the narrowed section 22 increases the impact force of the fluid, resulting in a better mixing effect. Simultaneously, the narrowed section 22 allows the second outlet 50Aa to have a larger 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 in the second outlet 50A, thus enhancing the mixing effect.
[0137] 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.
[0138] 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.
[0139] 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.
[0140] In some embodiments, please refer to Figures 12 and 20, 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.
[0141] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23, which forms a second water outlet 50Aa.
[0142] For example, the end of the pressurization structure 120 is connected to an expansion section, which forms a second water outlet 50Aa.
[0143] 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.
[0144] The constant diameter section 23 refers to the section where the flow area of the fluid remains basically unchanged along the flow direction.
[0145] An expansion section refers to a section where the flow area of the fluid increases along the flow direction.
[0146] In this embodiment, the fluid in the second water channel 50A 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 shape at a relatively fast speed.
[0147] 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.
[0148] 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.
[0149] In one embodiment, referring to Figure 12, the end of the pressurizing structure 120 extends into the mixing space 20a. The end of the pressurizing structure 120 extends into the mixing space 20a to increase the speed of the fluid entering the mixing space 20a. The fluid, accelerated by the pressurizing structure 120, enters the mixing space 20a through the end of the pressurizing structure 120. 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.
[0150] In some embodiments, referring to Figures 12 and 20, the garment processing device includes a turbulent structure 21, and the first water channel 40A and / or the second water channel 50A are provided with the turbulent structure 21, which is used to provide a circumferential velocity component to the fluid.
[0151] For example, the first water channel 40A is provided with a turbulent flow structure 21. As another example, the second water channel 50A is provided with a turbulent flow structure 21. Yet another example, both the first water channel 40A and the second water channel 50A are provided with turbulent flow structures 21.
[0152] The aforementioned circumferential velocity component refers to the fluid after passing through the turbulent structure 21, whose circumferential velocity component is not zero, and the circumferential direction extends around the water channel.
[0153] In this embodiment, after passing through the turbulence structure 21, the fluid generates a complex motion in multiple directions, including the circumferential and forward directions, thereby better mixing with the fluid in the mixing space 20a and improving mixing efficiency. It also allows the fluid ejected from the outlet 20ab to spread out in a roughly cone shape, resulting in a wider radiation range and better visual effect. In one embodiment, referring to Figures 12 and 20, the garment processing device includes a turbulence structure 21, which is disposed in the second water channel 50A to provide a circumferential velocity component to the fluid in the second water channel 50A. For example, the turbulence structure 21 is disposed in the liquid flow channel 130a.
[0154] The aforementioned circumferential velocity component refers to the fluid in the second water channel 50A after passing through the turbulent structure 21, whose velocity component in the circumferential direction of the second water channel 50A is not zero, and the circumferential direction of the second water channel 50A surrounds the extension direction of the second water channel 50A.
[0155] After passing through the turbulent structure 21, the fluid in the second water channel 50A generates a complex 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.
[0156] Understandably, the turbulent structure 21 can also increase the fluid velocity by limiting the flow area of the second water channel 50A in which it is located. This results in a greater difference in velocity between the two fluid streams entering the mixing space 20a, further promoting detergent dissolution.
[0157] In one embodiment, referring to Figures 12 and 20, the turbulence structure 21 includes one or more helical blades for guiding the helical motion of the fluid. For example, the helical blades are used to guide the helical motion of the fluid in the second water channel 50A. 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 when the fluid passes through.
[0158] For example, the turbulent structure 21 includes one or more helical blades that divide at least a portion of the length of the second waterway 50A into multiple sub-channels.
[0159] 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.
[0160] In some embodiments, referring to Figures 12 and 20, the outer edge of the helical blade along the helical direction is connected to the inner wall of the second water passage 50A, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the second water passage 50A. That is, there is a gap between the inner edge of the helical blade and the inner wall of the second water passage 50A, so that the inner wall of the second water passage 50A provides a connection support for the helical blade.
[0161] In one embodiment, referring to Figures 12 and 20, the pressurization structure 120 is located downstream of the turbulence structure 21. The fluid passes sequentially through the turbulence structure 21 and the pressurization structure 120, for example, the narrowing section 22, and is then ejected in a conical shape into the garment processing chamber.
[0162] In one embodiment, referring to Figure 12, the 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 greater 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 discharged from the mixing space 20a in a timely manner, reducing losses during the flow process.
[0163] In some embodiments, referring to Figures 9 to 13 and Figures 21 to 26, the garment handling device includes a dispenser box 140, which forms a detergent dispensing chamber 140a, which is connected to a first water path 40A. The detergent dispensing chamber 140a is part of the first water path 40A. The detergent dispensing chamber 140a is used to hold detergent. The detergent dispensing chamber 140a can be suitable for holding powdered laundry detergent, or it can be suitable for holding detergents with flow properties, such as liquid laundry detergent. The detergent dispensing chamber 140a is located upstream of the mixing space 20a. The water flow impacts the laundry detergent in the dispensing chamber to initially dissolve the detergent to form a detergent mixture solution, which then enters the mixing space 20a.
[0164] The number of detergent dispensing chambers 140a is unlimited; there can be one or more. Taking multiple detergent dispensing chambers 140a as an example, the multiple detergent dispensing chambers 140a can be arranged sequentially in a direction perpendicular to the vertical direction, such as in a left-right direction or a front-back direction. Each detergent dispensing chamber 140a can dispense detergents with different or the same functions.
[0165] For example, the upper surface of the dispenser box 140 forms an addition port that communicates with the detergent dispensing chamber 140a. The user can add detergent to the detergent dispensing chamber 140a from above through the addition port.
[0166] In some embodiments, referring to Figures 3 to 26, the garment handling device includes a detergent dispenser 30, which includes a mixing chamber 30d. A dispenser box 140 includes at least two detergent dispensing chambers 140a, each with a drain outlet 140b. The at least two drain outlets 140b communicate with the mixing chamber 30d. A first drain outlet 30b is provided on the side wall of the mixing chamber 30d. The detergent dispensing chambers 140a are located upstream of the mixing chamber 30d, which is located upstream of the mixing space 20a.
[0167] Please refer to Figures 9 and 26. The outlet 140b connects the detergent dispensing chamber 140a and the mixing chamber 30d. The detergent in the detergent dispensing chamber 140a enters the mixing chamber 30d through the outlet 140b. The mixing chamber 30d is used to hold the detergent mixture solution. The first drain outlet 30b is connected to the mixing chamber 30d and is used to drain the detergent mixture solution from the mixing chamber 30d.
[0168] The first water path 40A connects a water source, a detergent dispensing chamber 140a, a mixing chamber 30d, a first drain outlet 30b, and a mixing space 20a. That is, the detergent dispensing chamber 140a, the mixing chamber 30d, and the first drain outlet 30b constitute a part of the first water path 40A. Fluid from the water source flows through the detergent dispensing chamber 140a, the mixing chamber 30d, and the first drain outlet 30b. For example, fluid from the water source in the first water path 40A flows through the detergent dispensing chamber 140a and mixes with detergent to form a detergent mixture solution. The detergent mixture solution flows to the mixing chamber 30d, is discharged through the first drain outlet 30b, and flows into the mixing space 20a.
[0169] 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.
[0170] The fluid in the mixing chamber 30d can enter the mixing space 20a and then enter the garment processing chamber. In other words, the detergent mixture in the mixing chamber 30d eventually enters the garment processing chamber to process the clothes.
[0171] In this embodiment, at least two outlets 140b are connected to the mixing chamber 30d, so that the detergent in multiple detergent dispensing chambers 140a can enter the mixing chamber 30d and be discharged to the clothing processing chamber through the mixing chamber 30d, making the water path simple.
[0172] In some embodiments, the detergent in the detergent dispensing chamber 140a can be flushed with water to allow the detergent to enter the mixing chamber 30d. For example, a spray nozzle can spray water into the detergent dispensing chamber 140a, and the water flow impacts and washes the detergent in the dispensing chamber to generate a detergent mixture solution. The detergent mixture solution then enters the mixing chamber 30d through the outlet 140b.
[0173] In some embodiments, the spray nozzle may be formed on the detergent dispenser 30 or the workbench 80, etc.
[0174] In one embodiment, the spray nozzle may be located above the detergent dispensing chamber 140a. For example, the detergent dispenser 30 includes a lid and a body, with the lid positioned above the body and together defining a cavity, a portion of which may be a mixing chamber 30d, and the lid forming the spray nozzle.
[0175] In one embodiment, referring to Figures 7, 9, 17, 18, and 26, the detergent dispenser 30 includes an overflow chamber 30c, which receives fluid overflowing from the mixing chamber 30d. A second drain outlet 30a is provided on the side wall of the overflow chamber 30c. That is, the second drain outlet 30a communicates with the overflow chamber 30c and can be used to drain the detergent mixture solution from the overflow chamber 30c. Both the mixing chamber 30d and the overflow chamber 30c are part of the cavity of the detergent dispenser 30.
[0176] In this embodiment, when the liquid level in 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. When the liquid level in the mixing chamber 30d is higher than the overflow level, the excess fluid in the mixing chamber 30d 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.
[0177] In one embodiment, the mixing chamber 30d and the overflow chamber 30c can be distributed along the front-to-back direction, and the dimensions of the mixing chamber 30d and the overflow chamber 30c along the left-to-right direction can be relatively large, so that the mixing chamber 30d can be adapted to multiple detergent dispensing chambers 140a to hold the fluid from the detergent dispensing chambers 140a; the overflow chamber 30c has a moderate volume to receive the fluid overflowing from the mixing chamber 30d.
[0178] In one embodiment, the dispenser box 140 is removably disposed within the detergent dispenser 30, for example, within the cavity of the detergent dispenser 30. Exemplarily, the dispenser box 140 is removably disposed within the detergent dispenser 30; for example, at least a portion of the dispenser box 140 can be pulled out to the outside of the detergent dispenser 30, allowing the user to dispense detergent into the detergent dispensing chamber 140a. After dispensing or when washing clothes, the dispenser box 140 can be pushed back into the detergent dispenser 30.
[0179] It is understandable that the shape and size of the outlet 140b are not limited and can be set according to requirements.
[0180] In one embodiment, referring to Figures 6, 9, 17, and 26, the upper sidewall of the mixing chamber 30d has a filter hole 160a, and the outlet 140b is located above the mixing chamber 30d. The detergent mixture discharged from the outlet 140b enters the mixing chamber 30d after being filtered by the filter plate 160.
[0181] In one embodiment, referring to Figures 6, 9, 17 and 26, the garment processing device includes a filter plate 160 having filter holes 160a, the filter plate 160 being disposed within a detergent dispenser 30 to define a portion of the space within the detergent dispenser 30 as a mixing chamber 30d.
[0182] In one embodiment, referring to Figures 6, 9, 17, and 26, the laundry treatment device includes a water-retaining rib 170, a detergent dispenser 30 having a cavity, the water-retaining rib 170 extending upward from the wall of the cavity, and a filter plate 160 disposed within the cavity. The water-retaining rib 170, the filter plate 160, and a portion of the cavity surface together form a mixing chamber 30d. The filter plate 160 can be the upper sidewall of the mixing chamber 30d, the space above the mixing chamber 30d can be a receiving cavity 30e, and the space in front of the mixing chamber 30d can be an overflow cavity 30c. Exemplarily, the outlet 140b can be located within the receiving cavity 30e. The receiving cavity 30e and the mixing chamber 30d share the filter plate 160 as a sidewall. A filter hole 160a connects the receiving cavity 30e and the mixing chamber 30d, and the outlet 140b communicates with the receiving cavity 30e. The portion of the outlet 140b of the dispenser box 140 is located within the receiving cavity 30e.
[0183] In this embodiment, the thickness direction of the filter plate 160 can be aligned with the vertical direction. The fluid discharged from the outlet 140b flows sequentially through the receiving cavity 30e, the filter hole 160a, and the mixing cavity 30d. That is, the fluid discharged from the 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. The filter plate 160 can temporarily retain particles larger than or equal to the pore size of the filter hole 160a on its upper surface, while particles smaller than the pore size of the filter hole 160a can enter the mixing cavity 30d below, and then enter the mixing space 20a through the first outlet 140b. During the washing process, the detergent mixture from the washing dispensing chamber 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 smaller detergent particles entering the garment processing chamber, improving the cleaning effect.
[0184] Understandably, the aperture size and shape of the filter hole 160a can be set as needed. The shape of the filter hole 160a includes, but is not limited to, circles, ovals, polygons, or irregular shapes. Irregular shapes refer to irregular shapes.
[0185] In some embodiments, referring to Figures 6 and 17, the filter plate 160 may be generally flat. The filter plate 160 has a simple structure and is easy to manufacture.
[0186] In one embodiment, referring to Figures 3 to 26, the garment processing device includes a nozzle 130, which forms a liquid outlet channel 130b and a liquid flow channel 130a. The liquid outlet channel 130b is part of a first water path 40A, and the water outlet end of the liquid outlet channel 130b is the first water outlet end 40Aa. The liquid flow channel 130a is part of a second water path 50A, and the water outlet end of the liquid flow channel 130a is the second water outlet end 50Aa. By using the nozzle 130 to form part of the first water path 40A and the second water path 50A, the number of pipes laid in the garment processing device can be reduced, thus lowering the manufacturing difficulty.
[0187] At least one of the flow channel 130a and the outlet channel 130b carries a detergent mixture solution. For example, both the flow channel 130a and the outlet channel 130b may carry a detergent mixture solution. Another example is that the flow channel 130a carries a detergent mixture solution, while the outlet channel 130b carries other fluids. Yet another example is that the outlet channel 130b carries a detergent mixture solution, while the flow channel 130a carries other fluids.
[0188] In one embodiment, the liquid flow channel 130a delivers an aqueous solution, and the liquid outlet channel 130b delivers a detergent mixture solution. The aqueous solution delivered by the liquid flow channel 130a can further promote the dissolution of detergent, such as laundry powder, in the liquid outlet channel 130b.
[0189] In one embodiment, the flow velocity at the second outlet 50Aa is greater than the flow velocity at the first outlet 40Aa. On one hand, there is a velocity difference between the fluid discharged from the liquid flow channel 130a and the fluid discharged from the liquid outlet channel 130b. The flow velocity at the outlet of the liquid flow channel 130a is relatively high, which can increase the impact force of the fluid. The two fluids entering the mixing space 20a have different flow velocities; the faster one can impact and disturb the slower one, allowing the detergent to mix better when the two fluids converge, further promoting detergent dissolution. On the other hand, the relatively high flow velocity at the outlet of the liquid flow channel 130a can generate negative pressure in the surrounding area, causing the fluid at the outlet of the liquid outlet channel 130b to be drawn in under this negative pressure, improving the mixing effect.
[0190] In some embodiments, referring to Figures 12 and 20, a pressurization structure 120 and / or a turbulence structure 21 are disposed in a liquid flow channel 130a.
[0191] In one embodiment, referring to Figures 12, 25, and 26, the nozzle 130 forms a mixing space 20a. That is, the fluids of the first water path 40A and the second water path 50A both converge and mix within the nozzle 130.
[0192] In one embodiment, referring 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 and a mixing space 20a, and the tube 131 forms a liquid flow channel 130a. At least a portion of the tube 131 is inserted into the mixing space 20a. That is, a second water outlet 50Aa is formed in the tube 131. Exemplarily, 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.
[0193] In one embodiment, referring 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 sidewall of the mixing space 20a along the second direction, where the first and second directions intersect. 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, allowing the two fluids to converge and mix in the mixing space 20a.
[0194] In one embodiment, referring to Figures 10 to 12, the housing 132 has a liquid outlet 20ab. Exemplarily, the liquid outlet 20ab is formed on the sidewall of the housing 132 along a first direction. Fluid within the mixing space 20a is ejected through the liquid outlet 20ab to the nozzle 130.
[0195] As exemplarily, referring to Figures 10 to 12, the nozzle 130 also includes a connector tube 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 within the connector tube 133 forms part of the first water passage 40A, and the connector tube 133 can be used to connect a second pipe 42. The second pipe 42 delivers fluid into the nozzle 130 via the connector tube 133.
[0196] In one embodiment, referring to Figures 2, 10 to 12, the garment processing device includes a door seal ring 60, and a nozzle 130 is disposed 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.
[0197] In one embodiment, referring to Figures 2, 10 to 12, the space enclosed by the door seal ring 60 is part of the garment processing chamber, and the liquid outlet 20ab extends radially inward from the door seal ring 60. That is, the garment processing device can be a drum-type garment processing device. The fluid discharged from the liquid outlet 20ab can directly enter the space enclosed by the door seal ring 60, thereby directly entering the garment processing chamber.
[0198] 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.
[0199] In some embodiments, referring to Figures 3 to 12, the laundry treatment device includes a first pipe 41 and a second pipe 42. One end of the first pipe 41 is connected to an external water source, for example, connected to a water inlet valve 90, and the other end of the first pipe 41 is connected to the water inlet of a detergent dispenser 30 to guide water flow into the detergent dispenser 30. One end of the second pipe 42 is connected to a first drain outlet 30b, and the other end of the second pipe 42 is connected to a mixing space 20a to guide the fluid discharged from the first drain outlet 30b into the mixing space 20a. For example, the other end of the second pipe 42 is connected to a connector pipe 133. 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.
[0200] In some embodiments, referring to Figures 3 to 12, the garment processing device includes a third conduit 50, one end of which is introduced into a water source. The third conduit 50 is connected to a mixing space 20a for directing water from the water source into the mixing space 20a. For example, the third conduit 50 is connected to a cannula 131. In this embodiment, the space within the third conduit 50 defines a portion of a second water passage 50A.
[0201] 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.
[0202] The second pipe 42 mentioned above can be a single pipe or a combination of multiple pipe sections; there is no limitation on this.
[0203] The aforementioned third pipe 50 can be a single, complete pipe or composed of multiple pipe segments connected together; no restrictions are imposed here.
[0204] In some embodiments, the door seal ring 60 has a mounting opening through which the water outlet of the mixing space 20a passes and extends radially inward into the door seal ring 60. For example, a nozzle 130 is disposed within the door seal ring 60, and the sidewall of the nozzle 130 having a liquid outlet 20ab extends radially inward into the door seal ring 60. This facilitates the direct dispensing of the detergent mixture solution from the water outlet of the mixing space 20a into the laundry treatment chamber.
[0205] 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.
[0206] In some embodiments, the outer tub 11 has a water inlet, and the second drain outlet 30a is connected to the water inlet to guide the overflowing detergent mixture in the detergent box 30 to the outer tub 11, and then into the inner tub through the flow hole of the inner tub, which can play an auxiliary role in water intake.
[0207] For example, as shown in FIG1, the garment processing device further includes a water outlet pipe 70, which is connected to a second drain outlet 30a and a water inlet.
[0208] In some embodiments, referring to Figure 3, 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.
[0209] In one embodiment, the nozzle 130 is disposed on the worktable 80. The nozzle 130 may be a separate structure from the worktable 80, or at least a portion of the nozzle 130 may be formed on the worktable 80.
[0210] The nozzle 130 can be a separate structure from the worktable 80. That is, the nozzle 130 and the worktable 80 are manufactured independently and then assembled together by detachable or non-detachable connections. The worktable 80 and the nozzle 130 can be separate structures, which reduces the design and manufacturing difficulty of the worktable 80 and the nozzle 130.
[0211] In one embodiment, referring to Figures 13 to 17, the garment processing device includes a workbench 80, and at least a portion of a nozzle 130 is formed on the workbench 80.
[0212] "At least a portion of the nozzle 130 is formed in the worktable 80" means that at least a portion of the nozzle 130 is constituted by the solid structure of the worktable 80. For example, at least a portion of the nozzle 130 is integrally formed with at least a portion of the solid structure of the worktable 80. For instance, at least a portion of the nozzle 130 is integrally injection molded with at least a portion of the solid structure of the worktable 80, etc.
[0213] In this embodiment, part of the structure of the worktable 80 is a component of the nozzle 130. Thus, by reusing the worktable 80 as part of the nozzle 130, the number of parts can be reduced, materials used can be reduced, and material costs can be lowered.
[0214] In one embodiment, please refer to Figures 14 to 18. The garment processing device includes a partition 150, which is disposed on the lower side of the workbench 80. The partition 150 and the workbench 80 together form a liquid outlet channel 130b.
[0215] In this embodiment, the liquid outlet channel 130b is defined by the partition 150 and the worktable 80, which can reduce the number of pipes laid on the worktable 80, simplify the pipe layout, and reduce the manufacturing difficulty.
[0216] The partition 150 and the worktable 80 can be detachably or non-detachably connected. In some embodiments, the partition 150 and the worktable 80 can be welded or bonded. In some embodiments, the partition 150 and the worktable 80 can be snap-fitted, screwed, or bolted, etc.
[0217] The connection between the partition 150 and the worktable 80 can be sealed. This prevents fluid leakage at the connection between the partition 150 and the worktable 80.
[0218] For example, the connection between the partition 150 and the worktable 80 can be sealed by welding, adhesive bonding, or a sealing element. The sealing element can be a flexible structure that uses its elastic deformation to seal the gap at the connection between the partition 150 and the worktable 80. For example, the sealing element can be a flexible structure made of rubber and / or silicone.
[0219] In some embodiments, the worktable 80 forms a downward-opening slot, and the partition 150 closes the downward opening of the slot to form the liquid outlet channel 130b of the nozzle 130 and the mixing chamber 30d of the detergent cartridge 30. (Liquid outlet channel)
[0220] In some embodiments, as shown in Figures 22 to 26, a portion of the worktable 80 is recessed to form a liquid outlet channel 130b. That is, the partition 150 can be omitted, and the liquid outlet channel 130b for fluid flow can be formed entirely by utilizing the worktable 80, thus saving parts and reducing costs.
[0221] In one embodiment, referring to Figures 13 to 26, the worktable 80 forms a liquid outlet 20ab communicating with the mixing space 20a, which is located between the second water outlet 50Aa and the liquid outlet 20ab. The liquid outlet 20ab is formed on the worktable 80 to facilitate the downward spraying of fluid discharged from the liquid outlet 20ab into the clothing processing chamber under the influence of gravity and initial velocity. At least a portion of the space between the second water outlet 50Aa and the liquid outlet 20ab constitutes the mixing space 20a.
[0222] In some embodiments, referring to Figures 18 and 22, the liquid outlet 20ab is formed on the surface of the worktable 80 facing the clothing inlet 80a. This minimizes the possibility of structures on the worktable 80 obstructing the discharge of fluid from the liquid outlet 20ab.
[0223] In one embodiment, referring to Figures 16, 19, 20, and 23, the nozzle 130 includes a tube 131 forming a liquid flow channel 130a, and the worktable 80 forming a liquid outlet channel 130b. The tube 131 is inserted into the worktable 80. That is, the worktable 80 has an insertion hole into which the tube 131 is inserted. This design utilizes the worktable 80 to provide an installation position for the tube 131, simplifying the installation process and improving production efficiency. The tube 131 forming the liquid flow channel 130a has a simple structure, and the worktable 80 can provide an installation position for the tube 131.
[0224] In one embodiment, the partition 150 forms a socket, and the insertion tube 131 is inserted into the socket.
[0225] In some embodiments, the gap between the cannula 131 and the insertion hole can be sealed by a sealing structure. For example, the gap between the cannula 131 and the insertion hole can be sealed by a sealing ring.
[0226] The sealing structure can be a flexible structure, utilizing the elastic deformation of the sealing structure to seal the gap at the connection between the liquid flow channel 130a and the liquid outlet channel 130b. For example, the elastic deformation of the sealing structure can be used to seal the gap between the insertion tube 131 and the insertion hole. For instance, the sealing structure can be a flexible structure made of rubber and / or silicone.
[0227] In one embodiment, referring to Figures 20 and 23, at least a portion of the insertion tube 131 is inserted into the outlet channel 130b. This insertion can be a partial or complete insertion of the insertion tube 131 into the outlet channel 130b. Partial insertion of the insertion tube 131 into the outlet channel 130b facilitates connection of the portion of the insertion tube 131 outside the outlet channel 130b to other tubes or valves, etc.
[0228] In some embodiments, the inlet end of the cannula 131 is connected to a water outlet of the inlet valve 90. In this way, the inlet valve 90 can supply water to the cannula 131.
[0229] In some embodiments, at least a portion of the detergent dispenser 30 is formed on the workbench 80.
[0230] The statement that at least a portion of the detergent dispenser 30 is formed on the workbench 80 means that a portion of the solid structure of the workbench 80 constitutes at least a portion of the solid structure of the detergent dispenser 30. For example, at least a portion of the detergent dispenser 30 may be integrally formed with the workbench 80.
[0231] In this embodiment, at least a portion of the detergent box 30 is formed on the workbench 80, and a portion of the structure of the workbench 80 is reused as at least a portion of the detergent box 30, which can reduce the number of parts, simplify the structure, and save costs.
[0232] In one embodiment, the detergent dispenser 30 can be a separate structure from the workbench 80. That is, the detergent dispenser 30 and the workbench 80 are manufactured separately and then assembled together by a detachable or non-detachable connection.
[0233] For example, the insertion tube 131 and the worktable 80 can be separate structures. That is, the insertion tube 131 and the worktable 80 can be manufactured separately and then assembled.
[0234] For example, the housing 132 of the nozzle 130 can be formed on the worktable 80. That is, the housing 132 can be integrally formed with the worktable 80.
[0235] In another embodiment, a portion of the housing 132 is formed on the worktable 80, and another portion of the housing 132 can be a discrete structure. For example, a partition 150 constitutes another portion of the housing 132.
[0236] In some embodiments, referring to Figures 14 to 26, for a pulsator-type garment processing device with a worktable 80, the detergent dispenser 30 and the spray nozzle 130 can be part of the worktable 80. For example, the portion of the worktable 80 used to house the dispenser box 140 is the detergent dispenser 30. A portion of the worktable 80 is a component of the detergent dispenser 30 and the spray nozzle 130. Thus, by reusing the worktable 80 as part of the detergent dispenser 30 and the spray nozzle 130, the number of parts can be reduced, materials used can be reduced, and material costs can be lowered.
[0237] In one embodiment, referring to Figures 13 to 26, the surface of the workbench 80 facing the clothing inlet 80a has a suction port 80b, which communicates with the cavity of the detergent box 30. The dispenser box 140 enters and exits the detergent box 30 through the suction port 80b. When detergent needs to be added to the dispenser box 140, the dispenser box 140 can be pulled out of the detergent box 30 through the suction port 80b; when detergent addition is complete, the dispenser box 140 can be pushed into the detergent box 30 through the suction port 80b. During the washing process, the detergent and other fluids in the detergent inlet chamber 140a can flow through the first water path 40A, for example, sequentially through the receiving chamber 30e, the mixing chamber 30d, the liquid outlet channel 130b, and the mixing space 20a, and finally be dispensed into the clothing processing chamber from the liquid outlet 20ab; the detergent and other fluids in the receiving chamber 30e can also overflow into the overflow chamber 30c and enter the clothing processing chamber through the suction port 80b.
[0238] In some embodiments, as shown in Figures 17 to 26, a portion of the pumping port 80b of the workbench 80 may constitute a second drain port 30a.
[0239] In some embodiments, please refer to Figures 28, 29 and 30, the garment processing device includes a mixing space 20a and a nozzle 130, and the outlet 20ab of the mixing space 20a is disposed on the wall surface of the mixing space 20a.
[0240] The fluid in the first water path 40A and the fluid in the second water path 50A converge in the mixing space 20a. That is, the nozzle 130 has an inlet for the first water path 40A to introduce fluid into the mixing space 20a, and also has an inlet for the second water path 50A to introduce fluid into the mixing space 20a. The first water path 40A and the second water path 50A introduce their respective fluids into the mixing space 20a and mix them.
[0241] Unlike the first water channel 40A or the second water channel 50A, in the mixing space 20a, the two fluids influence each other, and their flow states (including velocity, direction, and density) change after entering the mixing space 20a. The mixed fluid in the mixing space 20a is sprayed into the garment processing chamber of the garment processing equipment through the outlet 20ab, which is located on the wall of the mixing space 20a. This means that the two fluids are directly released after mixing, without the need for additional piping at the outlet 20ab. During fluid mixing, ambient air can more easily enter the mixing space 20a through the outlet 20ab.
[0242] Please refer to Figure 34. The first water outlet 40Aa and the second water outlet 50Aa are located inside the nozzle 130. One of the first water outlet 40Aa and the second water outlet 50Aa is provided with a flow guide channel 201a, which is used to guide the fluid toward the other of the first water outlet 40Aa and the second water outlet 50Aa.
[0243] The aforementioned guidance of the fluid toward the first outlet 40Aa or the second outlet 50Aa means that after the fluid of the first water path 40A or the second water path 50A flows out of the guide channel 201a, it merges with the fluid of the first outlet 40Aa or the second outlet 50Aa, so as to minimize the distance between the first outlet 40Aa or the second outlet 50Aa.
[0244] As an example, after the fluid in the first water channel 40A flows out from the guide channel 201a, it merges with the fluid in the second water outlet 50Aa.
[0245] As an example, after the fluid in the second water channel 50A flows out from the guide channel 201a, it merges with the fluid in the first water outlet 40Aa.
[0246] Inside the nozzle 130, the guide channel 201a brings the first water path 40A and the second water outlet 50Aa closer together. After the fluid in the first water path 40A is sprayed out, it mixes with the fluid sprayed out of the second water path 50A. In this way, the impact force of the fluid when it is sprayed out enhances the mixing effect of the two fluids, thereby promoting the dissolution of detergent and improving the washing ratio.
[0247] In some embodiments, please refer to Figures 34 and 35. The water outlet direction of the second water outlet 50Aa of the second water passage 50A is towards the liquid outlet 20ab. The guide channel 201a is formed at the first water outlet 40Aa. The water outlet direction of the guide channel 201a intersects with the water outlet direction of the second water passage 50A.
[0248] Understandably, the guide channel 201a directs the fluid to the vicinity of the second outlet 50Aa of the second water path 50A. After the fluid from the second water path 50A is ejected, it merges with the fluid from the first water path 40A and largely maintains the original outlet pattern, driving the mixed fluid to be ejected from the outlet 20ab. Thus, there is no need to set up additional pipelines or pressurization structures, making the spray pattern of the outlet 20ab closer to the outlet pattern of the second water path 50A. The impact force of the fluid at the second outlet 50Aa of the second water path 50A can improve the spraying effect of the outlet 20ab.
[0249] In some embodiments, as shown in Figure 35, the cross-sectional area of the flow channel 201a gradually increases along the direction of fluid movement.
[0250] It should be noted that the flow passage 201a has the largest cross-sectional area at the end closest to the mixing space 20a. Under the guidance of the flow passage 201a, the fluid tends to concentrate towards the end closest to the mixing space 20a, so that it fills the mixing space 20a as much as possible and mixes thoroughly with the fluid at the outlet of the other water path.
[0251] In some embodiments, the fluid velocity at the first outlet 40Aa is lower than the fluid velocity at the second outlet 50Aa, and a guide channel 201a is formed at the first outlet 40Aa. That is, the guide channel 201a directs the slower-flowing fluid to the faster-flowing fluid, thereby utilizing the impact force of the faster-flowing second water channel 50A to fully mix it with the fluid in the first water channel 40A and enhance the foaming effect of the detergent.
[0252] As an optional embodiment, in which the fluid velocity at the first outlet 40Aa is less than the fluid velocity at the second outlet 50Aa, the cross-sectional area of the guide channel 201a gradually increases along the direction of fluid movement. Thus, the fluid velocity in the first water path 40A decreases in the guide channel 201a, the velocity difference between the first water path 40A and the second outlet 50Aa of the second water path 50A becomes greater, and the impact effect of the fluid in the second water path 50A on the fluid in the first water path 40A is better, resulting in a better mixing effect.
[0253] In some embodiments, referring to Figure 34, the water outlet cross-section (reference y) area of the flow channel 201a is larger than the water outlet cross-section (reference x) area of the second water outlet 50Aa, and smaller than the water outlet cross-section (reference z) area of the liquid outlet 20ab.
[0254] In this way, backflow caused by excessive flow difference between the first water channel 40A and the second water channel 50A can be effectively suppressed, that is, to prevent the fluid in the mixing space 20a from flowing back into the first water channel 40A as much as possible. In addition, the cross-sectional area of the first outlet end 40Aa is larger than that of the second outlet end 50Aa, so that when the detergent mixture enters the mixing space 20a from the first water channel 40A, the detergent components per unit volume have a larger contact area with the fluid in the mixing space 20a, which is conducive to more uniform mixing and more complete dissolution of the detergent components.
[0255] In some embodiments, please refer to Figure 35, a narrowing section 22 is provided at the end of the second water passage 50A to increase the flow velocity at the second outlet end 50Aa.
[0256] For example, in some embodiments, the end of the narrowed section 22 forms the second outlet 50Aa of the second water passage 50A. That is, the fluid in the second water passage 50A is ejected from the end of the narrowed section 22. In other embodiments, the end of the narrowed section 22 is also connected to a constant diameter section 23 and / or an expanded diameter section, which forms the second outlet 50Aa of the second water passage 50A.
[0257] In some embodiments, the outlet 20ab is used to spray water downwards at an angle toward the rear side of the garment processing chamber of the garment processing device. That is, referring to Figure 32, the outlet 20ab sprays water downwards and backwards, and the fluid at the outlet 20ab has both a downward velocity component and a velocity component along the axial rear side of the garment processing chamber. Specifically, the centerline n of the outlet 20ab forms an acute angle φ with the reference plane m. The reference plane m is perpendicular to the axis of the garment processing chamber.
[0258] The value of the acute angle φ is not limited. For example, the acute angle φ formed by the centerline n of the outlet 20ab and the reference plane m is 30° to 70°, i.e., 30° ≤ φ ≤ 70°. Examples include 30°, 45°, 50°, 60°, and 70°. This ensures that the fluid ejected from the outlet 20ab is sprayed onto the clothes inside the garment processing chamber as much as possible, quickly wetting the clothes, improving detergent utilization, and enhancing the cleaning effect.
[0259] In some embodiments, referring to FIG35, the nozzle 130 includes a housing 132 extending along a second direction R. The internal space of the housing 132 defines a mixing space 20a and a flow channel 201a. The sidewall of the housing 132 forms a liquid outlet 20ab, wherein the mixing space 20a is located on one side of the flow channel 201a along the second direction R.
[0260] It is understandable that in the nozzle 130, the housing 132 is provided with a liquid outlet 20ab, and the mixing space 20a communicating with the liquid outlet 20ab is located inside the housing 132. The guide channel 201a communicating with the mixing space 20a is also located inside the housing 132 along the second direction R. That is to say, the chambers inside the housing 132 respectively form the mixing space 20a and the guide channel 201a. This design structure is compact, which not only facilitates the arrangement of the guide channel 201a and the mixing space 20a, but also facilitates the connection between the first water path 40A and the second water path 50A and the nozzle 130.
[0261] In some embodiments, referring to FIG31, the nozzle 130 includes a connector tube 133 and an insert tube 131, which are arranged at intervals along a second direction R and are both connected to the housing 132. The space within the connector tube 133 forms part of a first water passage 40A, and the space within the insert tube 131 forms part of a second water passage 50A.
[0262] That is, the first water passage 40A extends into the nozzle 130 through the connector pipe 133, and the second water passage 50A extends into the nozzle 130 through the insertion pipe 131. The connector pipe 133 and the insertion pipe 131 are arranged side by side, and there is a certain distance between them. The orientation of the second direction R is not limited (for example, the radial direction perpendicular to the door seal ring 60), thus reserving space for the installation of the nozzle 130.
[0263] In some embodiments, please refer to FIG32, the housing 132 includes a first end wall 2011 and a second end wall 2012, the liquid outlet 20ab is formed on the first end wall 2011, the connector tube 133 and the insertion tube 131 are both connected to the second end wall 2012, and the housing 132 bends toward the rear side of the clothing processing chamber from the second end wall 2012 toward the first end wall 2011, and the first end wall 2011 is inclined toward the rear side of the clothing processing chamber.
[0264] In this embodiment, the housing 132 not only forms a chamber for fluid movement but also guides the fluid movement. The bending feature of the housing 132 allows for the transition between different flow directions of the fluid. For example, in an embodiment where both the connector tube 133 and the insertion tube 131 extend radially along the door seal ring 60, the bending feature of the housing 132 causes the fluid flow direction to transition from radial when entering the housing 132 to a downward tilt towards the rear of the garment processing chamber when ejected.
[0265] In some embodiments, referring to FIG33, the housing 132 includes a first sidewall 2013, a second sidewall 2014, and a transition connecting wall 2015. The first sidewall 2013 is located on the convex side of the housing 132 in the bending direction, and the second sidewall 2014 is located on the concave side of the housing 132 in the bending direction. The opposite ends of the first sidewall 2013 and the second sidewall 2014 along the second direction R are respectively connected by the transition connecting wall 2015.
[0266] In some embodiments, the first sidewall 2013 is arc-shaped and extends downward at an angle from the second endwall 2012 toward the first endwall 2011, so as to guide the fluid.
[0267] In some embodiments, please refer to FIG31, the transition connecting wall 2015 is curved from one end of the first sidewall 2013 to one end of the second sidewall 2014.
[0268] In some embodiments, please refer to Figures 34 and 35, the nozzle 130 includes a mouthpiece 202 disposed inside the mixing space 20a, the outlet of the mouthpiece 202 constituting the outlet of the second water passage 50A, and the outlet of the mouthpiece 202 facing the liquid outlet 20ab.
[0269] The fluid in the second water channel 50A is ejected from the outlet of the nozzle 202, impacting the detergent mixture in the first water channel 40A within the mixing space 20a, and then directly enters the garment processing chamber through the outlet 20ab. The shape of the second water outlet 50Aa experiences minimal attenuation within the mixing space 20a, approximating the shape when ejected from the outlet of the nozzle 202, thus driving the fluid within the mixing space 20a to be ejected.
[0270] For example, referring to Figure 32, the nozzle 202 has a narrowed section 22, and the turbulent flow structure 21 is disposed in the insertion tube 131 and located upstream of the narrowed section 22. After passing through the turbulent flow structure 21 and the narrowed section 22, the fluid in the second water path 50A is ejected from the outlet of the nozzle 202 with increased velocity and a circumferential velocity component. Thus, the water outlet 20ab can present a more visually appealing conical shape, and the ejected mixed fluid is more dispersed, directly spraying onto the clothes to be treated, improving the cleaning effect.
[0271] The nozzle 130 in this embodiment can be a one-piece component, meaning that the housing 132, nozzle 202, connector tube 133, and insertion tube 131 are integrally formed, for example, through injection molding or other processes. Of course, the nozzle 130 can also be a separate component, assembled after processing.
[0272] In some embodiments, referring to Figure 28, the nozzle 130 is radially inserted through the door seal ring 60, and the liquid outlet 20ab is located radially inside the door seal ring 60. That is, the door seal ring 60 provides mounting support for the nozzle 130.
[0273] The door seal ring 60 has a first mounting port (not shown) and a second mounting port (not shown). The connector tube 133 passes through the first mounting port, and the insertion tube 131 passes through the second mounting port. Therefore, in this embodiment, the nozzle 130 is connected to the door seal ring 60 via the connector tube 133 and the insertion tube 131, facilitating installation. During assembly, the nozzle 130 can be fixed first, and then the connector tube 133 and the insertion tube 131 can be connected to the first water passage 40A and the second water passage 50A, respectively.
[0274] This application also provides a detergent dispensing device for use in clothing processing equipment.
[0275] Referring to 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.
[0276] 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.
[0277] 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.
[0278] In one embodiment, referring to Figures 10 to 12, the first water path 40A includes a liquid outlet channel 130b, which has a first water outlet end 40Aa that communicates with 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 path 40A. Fluid in the liquid outlet channel 130b enters the mixing space 20a through the first water outlet end 40Aa.
[0279] In some embodiments, referring to Figures 10 to 12, the sidewall of the liquid outlet channel 130b has an opening to form a first water outlet end 40Aa. The liquid flow channel 130a is located on the same side of the liquid outlet channel 130b where the first water outlet end 40Aa is located. 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.
[0280] 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.
[0281] It should be noted that the first water outlet 40Aa refers to the part where the fluid in the liquid outlet channel 130b leaves the liquid outlet channel 130b, and the second water outlet 50Aa refers to the part where the fluid in the liquid flow channel 130a leaves the liquid flow channel 130a.
[0282] This application also provides a clothing processing device, which includes a detergent dispensing device and a clothing processing chamber as described in any embodiment of this application, with a liquid outlet 20ab delivering fluid into 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.
[0283] In one embodiment, referring to Figure 12, the liquid outlet channel 130b includes an expansion section, the largest flow area of which is the first water outlet end 40Aa. That is, the fluid in the liquid outlet channel 130b is ultimately ejected from the expansion section into the mixing space 20a. The expansion section can reduce head loss and promote the rapid discharge of fluid from the liquid outlet channel 130b.
[0284] 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.
[0285] In one embodiment, referring 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 an 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.
[0286] 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.
[0287] In one embodiment, referring 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.
[0288] 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.
[0289] 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.
[0290] 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.
[0291] In some embodiments, referring 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 that the inner wall of the liquid flow channel 130a provides connection support for the helical blade.
[0292] 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.
[0293] 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.
[0294] In one embodiment, referring to Figures 10 to 12, the portion of the liquid flow channel 130a within the mixing space 20a extends along a first direction, and 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 generally along the first direction, and the fluid discharged from the outlet channel 130b enters the mixing space 20a generally 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 causes the fluid at the first outlet end 40Aa to be drawn in, changing its flow direction towards the first direction and generating foam in the fluid, thus enhancing the mixing uniformity of the detergent, such as laundry powder.
[0295] 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.
[0296] In one embodiment, referring 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 sidewall of the housing 132, and a second water outlet 50Aa is formed in the tube 131. Exemplarily, 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.
[0297] 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.
[0298] In one embodiment, referring to Figures 10 to 12, the detergent dispensing device includes a nozzle 130 with 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.
[0299] In one embodiment, please refer to Figures 10 to 12. In Figures 10 to 12, the nozzle 130 forms an outlet 20ab on the sidewall along the first direction, and a first water outlet 40Aa is formed on the sidewall along the second direction of the mixing space 20a. The first direction and the second direction intersect.
[0300] In one embodiment, referring to Figures 10 to 12, the plane containing the outlet 20ab is used as the projection plane, and the projection of the second outlet 50Aa onto the projection plane is located 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.
[0301] In some embodiments, referring 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.
[0302] 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 a water source, the detergent passage, the first drain outlet 30b, and the liquid outlet 20ab. The second water path 50A connects a water source and a mixing space 20a.
[0303] The detergent pathway refers to the flow path of detergent within the detergent supply component.
[0304] 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.
[0305] 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.
[0306] In some embodiments, referring to Figures 3 to 12, the detergent supply assembly includes a detergent cartridge 30 and a dispenser cartridge 140 disposed within the detergent cartridge 30. The dispenser cartridge 140 has a detergent dispensing chamber 140a. The detergent cartridge 30 has a mixing chamber 30d and an overflow chamber 30c. The mixing chamber 30d is located below the dispenser cartridge 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 cartridge 30 has a second drain outlet 30a, which is disposed on the wall of the overflow chamber 30c.
[0307] 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.
[0308] 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.
[0309] 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.
[0310] 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.
