Description

Technical Field

[0001] This application relates to the field of garment processing technology, and more particularly to a spray nozzle and garment processing device. Background Technology

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] In related technologies, garment processing equipment includes a garment processing chamber and piping. The piping delivers detergent solution into the garment processing chamber, thereby dispensing detergent into the chamber to participate in garment processing. However, detergents, especially laundry powder, often do not dissolve completely and mix unevenly with water, resulting in insufficient utilization of the detergent, poor cleaning effect, and negatively impacting user experience. Summary of the Invention

[0004] In view of this, this application aims to provide a spray nozzle and clothing treatment device that can promote the dissolution of detergent.

[0005] This application provides a nozzle, the nozzle having:

[0006] Liquid flow channel;

[0007] The liquid outlet channel, at least one of the liquid flow channel and the liquid outlet channel, is used to convey a detergent mixture solution; at least one of the liquid flow channel and the liquid outlet channel is provided with a pressurization structure and / or a turbulence structure, the pressurization structure being used to increase the flow rate of the fluid, and the turbulence structure being used to provide a circumferential velocity component to the fluid.

[0008] In some embodiments, the pressurizing structure includes a narrowed section, which increases the flow velocity at the outlet end of the liquid flow channel where the pressurizing structure is located and / or at the outlet end of the liquid outlet channel.

[0009] In some embodiments, the turbulent structure includes one or more helical blades for guiding the helical motion of the fluid.

[0010] In some embodiments, the pressurizing structure and the turbulent structure are disposed in the same channel, and the pressurizing structure is located downstream of the turbulent structure.

[0011] In some embodiments, the liquid outlet channel has a first water outlet end, the liquid flow channel has a second water outlet end, and the projections of the axes of the first water outlet end and the second water outlet end in the horizontal plane intersect.

[0012] In some embodiments, the nozzle forms a mixing space, and both the liquid flow channel and the liquid outlet channel are connected to the mixing space.

[0013] In some embodiments, the nozzle has a liquid outlet communicating with the mixing space, and the second water outlet end of the liquid flow channel faces the liquid outlet.

[0014] In some embodiments, the nozzle includes a housing and a tube, the housing forming the liquid outlet channel and the mixing space, the tube forming the liquid flow channel, and at least a portion of the tube being inserted into the mixing space.

[0015] This application embodiment also provides a garment processing device, including:

[0016] Garment processing chamber;

[0017] In any of the above-described nozzles, both the liquid flow channel and the liquid outlet channel deliver fluid to the clothing processing chamber.

[0018] In some embodiments, the garment processing device includes a door seal ring, and the spray nozzle is disposed on the door seal ring; or,

[0019] The garment processing equipment includes a workbench, and the spray nozzle is disposed on the workbench.

[0020] The nozzle provided in this application embodiment uses a pressurizing structure to accelerate the fluid, and a turbulent structure to provide a circumferential velocity component to the fluid. The turbulent structure also causes the fluid to disperse in a cone shape. The fluid transported by the liquid outlet channel and the fluid transported by the liquid flow channel converge and mix. The mixed fluid enters the garment processing chamber and participates in garment processing. There is a velocity difference between the fluid in the liquid outlet channel and the fluid in the liquid flow channel. For example, the fluid in the liquid flow channel is accelerated by the pressurizing structure and / or the turbulent structure, and the velocity of the fluid in the liquid flow channel is greater than that of the fluid in the liquid outlet channel. The two fluids have different velocities, and 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. In other words, the nozzle can promote solution mixing and also cause the fluid to disperse in a cone shape. Attached Figure Description

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

[0051] 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.

[0052] 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.

[0053] Clothing processing equipment can be either drum-type or pulsator-type, such as drum washing machines or pulsator washing machines.

[0054] The garment processing equipment includes a garment processing chamber for holding garments.

[0055] 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.

[0056] The axis of inclination refers to the axis of the garment processing chamber being oblique to the horizontal direction.

[0057] Please see Figure 1 The garment processing equipment may include a drum assembly 10, the axis of which may extend vertically, horizontally, or obliquely. The internal space of the drum assembly 10 may be at least a portion of the garment processing chamber.

[0058] In some embodiments, please refer to Figure 1 and Figure 2 The garment handling device may include a door seal ring 60. The axis of the drum assembly 10 extends horizontally or inclined, 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.

[0059] In some embodiments, please refer to Figure 13 The garment processing equipment includes a worktable 80, and the axis of the drum assembly 10 extends vertically. The worktable 80 can be disposed above the drum assembly 10. The worktable 80 constitutes the exterior surface of the garment processing equipment. The garment processing equipment in this embodiment is also referred to as a pulsator-type garment processing equipment, such as a pulsator washing machine.

[0060] Please see 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] In some embodiments, the inner cylinder may be generally hollow and cylindrical.

[0065] In some embodiments, please refer to Figure 1 The drum assembly 10 includes an outer drum 11, and an inner drum can be disposed within the outer drum 11. The outer drum 11 is used to hold water for washing clothes, and the inner drum is used to hold clothes.

[0066] 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.

[0067] In some embodiments, please refer to Figure 1 The outer barrel 11 can be roughly hollow and cylindrical.

[0068] 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.

[0069] 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.

[0070] In some embodiments, the garment handling equipment includes a housing, with the cylindrical assembly 10 disposed within the housing.

[0071] In some embodiments, the housing may be approximately hexahedral in shape, such as a cube or a cuboid.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] This application provides a spray head 130 for use in a garment processing device. (See also...) Figures 10 to 26 The nozzle 130 has a flow channel 130a and a discharge channel 130b, at least one of which is provided with a pressurizing structure 120 and / or a turbulent flow structure 21. The pressurizing structure 120 is used to increase the flow rate of the fluid, and the turbulent flow structure 21 is used to provide a circumferential velocity component to the fluid.

[0077] Taking the liquid outlet channel 130b as an example, which is equipped with a pressurizing structure 120 and a turbulent flow structure 21, the pressurizing structure 120 is used to increase the flow rate of the fluid in the liquid outlet channel 130b, and the turbulent flow structure 21 is used to provide a circumferential velocity component to the fluid in the liquid outlet channel 130b.

[0078] Taking the liquid flow channel 130a as an example, which is provided with a pressurizing structure 120 and a turbulent flow structure 21, the pressurizing structure 120 is used to increase the flow velocity of the fluid in the liquid flow channel 130a, and the turbulent flow structure 21 is used to provide a circumferential velocity component to the fluid in the liquid flow channel 130a.

[0079] Taking a flow channel 130a equipped with a turbulent structure 21 as an example, the aforementioned circumferential velocity component refers to the fact that the velocity component of the fluid in the flow channel 130a after passing through the turbulent structure 21 is not zero in the circumferential direction of the flow channel 130a, which surrounds the extension direction of the flow channel 130a. After passing through the turbulent structure 21, the fluid in the flow channel 130a generates a complex motion in multiple directions, including the circumferential and forward directions. The turbulent structure 21 can also increase the fluid velocity by limiting the flow area of ​​the region in the flow channel 130a in which it is located.

[0080] It is understandable that when the liquid outlet channel 130b is equipped with a turbulent flow structure 21, the principle is similar to the above principle, and will not be repeated here.

[0081] The provision of a pressurization structure 120 and / or a turbulence structure 21 in at least one of the liquid flow channel 130a and the liquid outlet channel 130b means that at least one of the liquid flow channel 130a and the liquid outlet channel 130b is provided with at least one of the pressurization structure 120 and the turbulence structure 21.

[0082] In one embodiment, the liquid flow channel 130a is provided with one of the pressurization structure 120 and the turbulence structure 21, while the liquid outlet channel 130b is not provided with either the pressurization structure 120 or the turbulence structure 21.

[0083] In one embodiment, the liquid flow channel 130a is provided with two of the pressurization structure 120 and the turbulence structure 21, while the liquid outlet channel 130b is not provided with the pressurization structure 120 and the turbulence structure 21.

[0084] In one embodiment, the liquid outlet channel 130b is provided with one of the pressurization structure 120 and the turbulence structure 21, while the liquid flow channel 130a is not provided with either the pressurization structure 120 or the turbulence structure 21.

[0085] In one embodiment, the liquid outlet channel 130b is provided with two of the pressurization structure 120 and the turbulence structure 21, while the liquid flow channel 130a is not provided with the pressurization structure 120 and the turbulence structure 21.

[0086] In one embodiment, one of the liquid flow channel 130a and the liquid outlet channel 130b is provided with a pressurization structure 120, and the other of the liquid flow channel 130a and the liquid outlet channel 130b is provided with a turbulence structure 21.

[0087] In one embodiment, both the liquid flow channel 130a and the liquid outlet channel 130b are provided with a pressurization structure 120 and a turbulence structure 21.

[0088] The above examples illustrate embodiments in which the pressurization structure 120 and the turbulence structure 21 are provided in the liquid flow channel 130a and the liquid outlet channel 130b. Other embodiments can be obtained by those skilled in the art based on the above examples, and will not be listed one by one here.

[0089] At least one of the flow channel 130a and the outlet channel 130b is used to convey a detergent mixture solution. For example, both the flow channel 130a and the outlet channel 130b may convey a detergent mixture solution. Another example is that the flow channel 130a conveys a detergent mixture solution, while the outlet channel 130b conveys other fluids. Yet another example is that the outlet channel 130b conveys a detergent mixture solution, while the flow channel 130a conveys other fluids.

[0090] 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.

[0091] The function of detergent is not limited. For example, the function of detergent includes, but is not limited to, cleaning, softening or fragrance.

[0092] The type of detergent is not limited, and detergents include, but are not limited to, cleaning agents, fabric softeners, and / or fragrances, etc.

[0093] The form of the cleaning agent is not limited; it can be powdered laundry detergent or liquid laundry detergent, etc.

[0094] 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.

[0095] It is understandable that both the liquid flow channel 130a and the liquid outlet channel 130b are used for circulating fluids, such as detergent mixtures and water.

[0096] The fluid in the liquid flow channel 130a and the fluid in the liquid outlet channel 130b can converge, that is, the fluid in the liquid flow channel 130a and the fluid in the liquid outlet channel 130b can come into contact and mix.

[0097] The nozzle provided in this embodiment uses a pressurizing structure 120 to accelerate the fluid, and a turbulent flow structure 21 to provide a circumferential velocity component to the fluid. The turbulent flow structure 21 also causes the fluid to disperse in a cone shape. The fluid transported by the outlet channel 130b and the fluid transported by the flow channel 130a converge and mix. The mixed fluid enters the garment processing chamber and participates in garment processing. There is a velocity difference between the fluid in the outlet channel 130b and the fluid in the flow channel 130a. For example, the fluid in the flow channel 130a is accelerated by the pressurizing structure 120 and / or the turbulent flow structure 21, and the velocity of the fluid in the flow channel 130a is greater than that of the fluid in the outlet channel 130b. The two fluids have different velocities, and 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. In other words, the nozzle 130 can promote solution mixing and also cause the fluid to disperse in a cone shape.

[0098] 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.

[0099] This application provides a garment processing device; please refer to [link / reference]. Figure 2 , Figure 10 , Figure 12 , Figure 15 as well as Figure 26 The garment processing device includes a garment processing chamber and a nozzle as described in any embodiment of this application. Both the liquid flow channel 130a and the liquid outlet channel 130b deliver fluid to the garment processing chamber. The fluid output from the liquid flow channel 130a and the fluid output from the liquid outlet channel 130b can converge in the air or in the mixing space 20a. The fluids delivered by both the liquid flow channel 130a and the liquid outlet channel 130b are used to process garments.

[0100] It should be noted that, for ease of description, the outlet end of the liquid flow channel 130a is defined as the second outlet end 50Aa, and the outlet end of the liquid flow channel 130b is defined as the first outlet end 40Aa. The following description assumes that the liquid flow channel 130a is equipped with a pressurization structure 120 and / or a turbulence structure 21.

[0101] In one embodiment, please refer to Figure 12 and Figure 26 The liquid outlet channel 130b has a first water outlet end 40Aa, and the liquid flow channel 130a has a second water outlet end 50Aa. The projections of the axes of the first water outlet end 40Aa and the second water outlet end 50Aa in the horizontal plane intersect. That is, with the horizontal plane as the projection plane, the projections of the axes of the first water outlet end 40Aa and the second water outlet end 50Aa intersect.

[0102] It should be noted that the first outlet 40Aa refers to the part where the fluid in the liquid flow channel 130b leaves the liquid flow channel 130b; when the liquid flow channel 130b is connected to the mixing space 20a, the first outlet 40Aa can also be understood as the boundary between the liquid flow channel 130b and the mixing space 20a. The second outlet 50Aa refers to the part where the fluid in the liquid flow channel 130a leaves the liquid flow channel 130a; when the liquid flow channel 130b is connected to the mixing space 20a, the second outlet 50Aa can also be understood as the boundary between the liquid flow channel 130a and the mixing space 20a.

[0103] The axis of the first outlet 40Aa refers to the straight line passing through the center point of the flow section of the first outlet 40Aa. The axis of the second outlet 50Aa refers to the straight line passing through the center point of the flow section of the second outlet 50Aa. The liquid outlet 20ab is the outlet of the mixing space 20a, and the axis of the liquid outlet 20ab refers to the straight line passing through the center point of the flow section of the liquid outlet 20ab.

[0104] The flow cross section is a section taken perpendicular to the streamline cluster. When the streamline clusters are not parallel to each other, the flow cross section is a curved surface; when the streamline clusters are parallel straight lines, the flow cross section is a plane.

[0105] The liquid flow channel 130a is equipped with a pressurization structure 120 and / or a turbulence structure 21, and the flow velocity at the second outlet 50Aa is greater than that 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 outlet channel 130b. The relatively higher flow velocity at the second outlet 50Aa increases the impact force of the fluids. The faster flow can impact and disturb the slower flow, allowing the detergent to mix better when the two fluids meet, further promoting detergent dissolution. On the other hand, the relatively high flow velocity at the second outlet 50Aa generates negative pressure in the surrounding area, causing the fluid at the first outlet 40Aa to be drawn in under this negative pressure, improving the mixing effect.

[0106] In this embodiment, both the liquid outlet channel 130b and the liquid flow channel 130a are circulated with fluid. The fluid flowing through the liquid outlet channel 130b is ejected approximately along the axis of the first water outlet 40Aa, and the fluid flowing through the liquid flow channel 130a is ejected approximately along the axis of the second water outlet 50Aa. The projections of the axes of the first water outlet 40Aa and the second water outlet 50Aa in the horizontal plane intersect. In this way, the fluid ejected from the first water outlet 40Aa and the fluid ejected from the second water outlet 50Aa can converge. When the two fluids converge, they mix and impact each other, which can further promote the dissolution of detergent and facilitate the application of detergent with bubbles to clothes, thereby improving the cleaning effect.

[0107] In one embodiment, please refer to Figure 12 , Figure 25 as well as Figure 26 The nozzle 130 has a mixing space 20a, and both the liquid flow channel 130a and the liquid outlet channel 130b are connected to the mixing space 20a. That is, both the first water outlet end 40Aa and the second water outlet end 50Aa are connected to the mixing space 20a. The fluid in the liquid flow channel 130a and the fluid in the liquid outlet channel 130b both enter the mixing space 20a and mix within the nozzle 130.

[0108] In this embodiment, the pressurizing structure 120 increases the speed of the fluid in the liquid flow channel 130a, and the turbulent flow structure 21 provides a circumferential velocity component to the fluid in the liquid flow channel 130a. There is a velocity difference between the fluid in the outlet channel 130b and the fluid in the liquid flow channel 130a. The two fluids entering the mixing space 20a have different flow velocities, one fast and one slow. The one with a faster flow velocity can impact and disturb the one with a slower flow velocity, thereby improving the mixing effect and allowing the detergent, such as laundry powder, to dissolve more fully.

[0109] It should be noted that the mixing space 20a can be a cavity formed in a solid structure.

[0110] 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.

[0111] In one embodiment, the fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa can converge in the air, and the convergence area can be located within the garment processing chamber. The nozzle may not have a mixing space 20a; the fluids discharged from the second water outlet 50Aa and the first water outlet 40Aa directly converge in the air, with the convergence area located within the garment processing chamber. In this way, the fluids discharged from the second water outlet 50Aa and the first water outlet 40Aa promote the dissolution of detergent, such as laundry powder. Because the convergence area is located within the garment processing chamber, the distance from the convergence area to the garment being treated by the mixed fluids from the first water path 40A and the second water path 50A can be shortened, reducing the degree of foam breaking and facilitating the application of foamy detergent to the garment, thereby improving the cleaning effect.

[0112] In one embodiment, please refer to Figures 10 to 12 , Figure 19 as well as Figure 26 The nozzle 130 has a liquid outlet 20ab communicating with the mixing space 20a. The liquid outlet 20ab is used to discharge the fluid within the mixing space 20a. It is understood that the liquid outlet 20ab can penetrate the outer surface of the solid structure in which it is located.

[0113] After passing through the turbulent structure 21, the fluid in the liquid flow channel 130a undergoes 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. The pressurizing structure 120 accelerates the fluid in the liquid flow channel 130a, while the turbulent structure 21 provides a circumferential velocity component to the fluid in the liquid flow channel 130a. The fluid transported by the 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 then discharged from the outlet 20ab and enters the garment processing chamber to participate in garment processing.

[0114] In one embodiment, please refer to Figure 12 , Figure 19 as well as Figure 26 The second outlet end 50Aa of the liquid flow channel 130a faces the outlet 20ab. "The second outlet end 50Aa facing the outlet 20ab" means that the orientation of the second outlet end 50Aa is the same as the orientation of the outlet 20ab. For example, both the second outlet end 50Aa and the outlet 20ab face the same side in the first direction. In other words, the axis of the second outlet end 50Aa is parallel to or coincides with the axis of the outlet 20ab.

[0115] 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.

[0116] In one embodiment, please refer to Figure 12 , Figure 19 as well as Figure 26 With the plane containing the outlet 20ab as the projection plane, the projection of the second outlet 50Aa lies within the projection range of the outlet 20ab. For example, the flow area of ​​the outlet 20ab can be larger than the flow area of ​​the second outlet 50Aa. This prevents misalignment between the outlet of the liquid flow channel 130a and the outlet 20ab, thus avoiding changes in fluid flow direction.

[0117] In one embodiment, please refer to Figure 2 , Figure 10 , Figure 12 , Figure 15 as well as Figure 26 The liquid outlet 20ab is directly connected to the clothing processing chamber.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] In one embodiment, please refer to Figure 12 The end of the pressurizing structure 120 extends into the mixing space 20a. This extension increases the speed of the fluid entering the mixing space 20a. The increased speed of the fluid, after being accelerated by the pressurizing structure 120, allows it to enter the mixing space 20a through its end. The increased impact force of the accelerated fluid better agitates the fluid within the mixing space 20a, improving the mixing effect and increasing the washing ratio.

[0123] In one embodiment, please refer to Figure 12 and Figure 20 The pressurizing structure 120 includes a narrowed section 22, which increases the flow velocity at the outlet end of the liquid flow channel 130a and / or the outlet end of the liquid flow channel 130b where the pressurizing structure 120 is located. Taking the liquid flow channel 130a with the pressurizing structure 120 as an example, the narrowed section 22 increases the flow velocity at the second outlet end 50Aa of the liquid flow channel 130a. Taking the outlet channel 130b with the pressurizing structure 120 as an example, the narrowed section 22 increases the flow velocity at the first outlet end 40Aa of the outlet channel 130b.

[0124] In this embodiment, the narrowing section 22 refers to the section where the flow area of ​​the fluid decreases along the flow direction. By limiting the flow area of ​​the fluid, the narrowing section 22 can increase the impact force of the fluid, resulting in a better mixing effect. Taking the liquid flow channel 130a equipped with a pressurizing structure 120 as an example, the narrowing section 22 enables the second water outlet 50Aa to have a larger jet velocity, which can generate a significant negative pressure in a relatively large surrounding area. This negative pressure causes the fluid at the first water outlet 40Aa to be drawn in and mixed with the fluid in the second water channel 50A, thus improving the mixing effect.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] In some embodiments, please refer to Figure 12 and Figure 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.

[0129] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23, which forms a second water outlet 50Aa.

[0130] For example, the end of the pressurization structure 120 is connected to an expansion section, which forms a second water outlet 50Aa.

[0131] 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.

[0132] The constant diameter section 23 refers to the section where the flow area of ​​the fluid remains basically unchanged along the flow direction.

[0133] An expansion section refers to a section where the flow area of ​​the fluid increases along the flow direction.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] In one embodiment, please refer to Figure 12 and Figure 20 The turbulence structure 21 includes one or more helical blades, which guide the helical motion of the fluid. Taking the liquid flow channel 130a with the turbulence structure 21 as an example, the helical blades guide the helical motion of the fluid in the liquid flow channel 130a. A helical blade is a blade with a helical shape, extending along 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.

[0138] 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.

[0139] 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.

[0140] In some embodiments, please refer to Figure 12 and Figure 20 The outer edge of the helical blade along the helical direction is connected to the inner wall of the liquid flow channel 130a, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the liquid flow channel 130a. That is, there is a gap between the inner edge of the helical blade and the inner wall of the liquid flow channel 130a, so the inner wall of the liquid flow channel 130a provides connection support for the helical blade.

[0141] In some embodiments, the outer edge of the helical blade along the helical direction is connected to the inner wall of the liquid outlet channel 130b, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the liquid outlet channel 130b. That is, there is a gap between the inner edge of the helical blade and the inner wall of the liquid outlet channel 130b, so that the inner wall of the liquid outlet channel 130b provides connection support for the helical blade.

[0142] In one embodiment, please refer to Figure 12 and Figure 20 The pressurizing structure 120 and the turbulent flow structure 21 are disposed in the same channel, with the pressurizing structure 120 located downstream of the turbulent flow structure 21. The channel can be either the liquid flow channel 130a or the liquid outlet channel 130b. For example, the pressurizing structure 120 and the turbulent flow structure 21 can be disposed in the same liquid flow channel 130a. Alternatively, the pressurizing structure 120 and the turbulent flow structure 21 can be disposed in the same liquid outlet channel 130b.

[0143] In this embodiment, the fluid passes through the turbulent structure 21 and the pressurizing structure 120, such as the narrowing section 22, and is then ejected into the clothing processing chamber with a conical shape.

[0144] In one embodiment, please refer 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 longer than the fluid path between the pressurizing structure 120 and the outlet 20ab. This allows the fluid to be effectively accelerated by the turbulent structure 21 and the pressurizing structure 120, and to be promptly discharged from the mixing space 20a, reducing losses during the flow process.

[0145] In one embodiment, please refer to Figures 10 to 12 The nozzle 130 includes a housing 132 and a tube 131. The housing 132 forms a liquid outlet channel 130b 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. For example, the port of the tube 131 located within the mixing space 20a is the second water outlet 50Aa. The nozzle 130 has a simple structure and is easy to manufacture.

[0146] In one embodiment, please refer to Figures 10 to 12 The port of the insertion tube 131 facing the first direction is the second water outlet 50Aa, and the first water outlet 40Aa is formed on the side wall of the mixing space 20a along the second direction, 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, and the two fluids converge and mix in the mixing space 20a.

[0147] In one embodiment, please refer to Figures 10 to 12 The housing 132 has a liquid outlet 20ab. For example, 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 outside of the nozzle 130.

[0148] For example, please refer to Figures 10 to 12 The nozzle 130 also includes a connector pipe 133, which is connected to the housing 132 and communicates with the end of the liquid outlet channel 130b away from the first water outlet end 40Aa. The space inside the connector pipe 133 forms part of the first water passage 40A, and the connector pipe 133 can be used to connect to a second pipe 42. The second pipe 42 delivers fluid to the nozzle 130 via the connector pipe 133.

[0149] In one embodiment, please refer to Figure 2 , Figures 10 to 12 The garment processing equipment 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.

[0150] In one embodiment, please refer to Figure 2 , Figures 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. In other words, 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, and thus directly enter the garment processing chamber.

[0151] 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.

[0152] In one embodiment, please refer to Figures 13 to 17 The garment processing equipment includes a workbench 80 and a spray nozzle 130 disposed on the workbench 80. The spray nozzle 130 may be a separate structure from the workbench 80, or at least a portion of the spray nozzle 130 may be formed on the workbench 80.

[0153] The nozzle 130 can be a separate structure from the worktable 80. That is, the nozzle 130 and the worktable 80 are manufactured separately and then assembled together by a detachable or non-detachable connection.

[0154] "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.

[0155] In other words, part of the structure of the worktable 80 is a component of the nozzle 130. In this way, the worktable 80 can be reused as part of the nozzle 130, which can reduce the number of parts, reduce the amount of materials used, and reduce material costs.

[0156] In one embodiment, please refer to Figures 13 to 15 The garment processing equipment includes a partition 150, which is located on the lower side of the workbench 80. The partition 150 and the workbench 80 together form a liquid outlet channel 130b.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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 box 30.

[0162] In some embodiments, please refer to Figures 22 to 26 The worktable 80 is partially recessed to form a liquid outlet channel 130b. In other words, the partition 150 can be omitted, and the worktable 80 can be used entirely to form the liquid outlet channel 130b for fluid flow. This can save parts and reduce costs.

[0163] In one embodiment, please refer to Figure 19 , Figure 23 and Figure 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.

[0164] In some embodiments, please refer to Figure 18 and Figure 22 The liquid outlet 20ab is formed on the surface of the worktable 80 facing the clothing inlet 80a. In this way, the obstruction of the liquid outlet 20ab by the structure on the worktable 80 can be avoided as much as possible.

[0165] In one embodiment, please refer to Figures 13 to 26 The nozzle 130 includes a tube 131, which forms a liquid flow channel 130a. The worktable 80 forms a liquid outlet channel 130b, and the tube 131 is inserted into the worktable 80. In other words, 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 forms the liquid flow channel 130a, resulting in a simple structure, and the worktable 80 provides an installation position for the tube 131.

[0166] In one embodiment, the partition 150 forms a socket, and the insertion tube 131 is inserted into the socket.

[0167] 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.

[0168] 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.

[0169] In one embodiment, please refer to Figure 15 and Figure 16At 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. The 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.

[0170] 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.

[0171] Please see Figures 3 to 26 The garment processing equipment includes a first water channel 40A and a second water channel 50A. At least one of the first water channel 40A and the second water channel 50A is used for the flow of a detergent mixture solution, the liquid outlet channel 130b is part of the first water channel 40A, and the liquid flow channel 130a is part of the second water channel 50A.

[0172] For example, both the first water channel 40A and the second water channel 50A are used to circulate the detergent mixture solution. As another example, the first water channel 40A is used to circulate the detergent mixture solution, and the second water channel 50A is used to circulate other fluids. Yet another example, the second water channel 50A is used to circulate the detergent mixture solution, and the first water channel 40A is used to circulate other fluids.

[0173] It should be noted that in the embodiments of this application, the first water path 40A refers to the flow path of the fluid and does not specifically refer to a pipe structure. The second water path 50A refers to the flow path of the fluid and does not specifically refer to a pipe structure.

[0174] 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.

[0175] 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.

[0176] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 13 The garment processing equipment includes a water inlet valve 90, which is connected to a water source such as a tap water pipe. The first water path 40A and the second water path 50A can be connected to different water inlet valves 90, or they can be connected to the same water inlet valve 90; this is not limited here. As an optional embodiment, the garment processing equipment includes a circulation pump, with one of the first water path 40A and the second water path 50A connected to the water inlet valve 90, and the other connected to the circulation pump of the garment processing equipment.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] In one embodiment, please refer to Figures 12 to 26 The fluid in the first water path 40A is discharged through the first outlet 40Aa, and the fluid in the second water path 50A is discharged through the second outlet 50Aa. By using the nozzle 130 as part of the first water path 40A and the second water path 50A, the amount of piping required for the garment processing equipment can be reduced, thus lowering the manufacturing difficulty.

[0181] In some embodiments, please refer to Figure 3 , Figure 9 and Figure 26 The garment handling equipment 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 used to hold powdered laundry detergent, or it can be used to hold 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, forming a detergent mixture solution, which then enters the mixing space 20a.

[0182] 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.

[0183] 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.

[0184] In some embodiments, please refer to Figures 3 to 26 The garment handling equipment 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.

[0185] 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.

[0186] The detergent dispensing chamber 140a, the mixing chamber 30d, and the first drain outlet 30b constitute part of the first water path 40A. Fluid from a water source flows through the detergent dispensing chamber 140a, the mixing chamber 30d, and the first drain outlet 30b. For example, fluid from a 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 and is discharged through the first drain outlet 30b, and then flows to the mixing space 20a.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] In some embodiments, the spray nozzle may be formed on the detergent dispenser 30 or the workbench 80, etc.

[0192] 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.

[0193] In one embodiment, please refer to Figures 6 to 9 ,as well as Figures 17 to 26 The detergent dispenser 30 includes an overflow chamber 30c, which collects 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 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.

[0194] 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.

[0195] 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.

[0196] In one embodiment, please refer to Figure 9 , Figure 13 and Figure 17 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.

[0197] It is understandable that the shape and size of the outlet 140b are not limited and can be set according to requirements.

[0198] In one embodiment, please refer to Figures 6 to 9 The upper side wall 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.

[0199] In one embodiment, please refer to Figures 6 to 9 , Figure 17 as well as Figure 18 The garment processing equipment includes a filter plate 160 with filter holes 160a, which is disposed inside a detergent dispenser 30 to define a portion of the space inside the detergent dispenser 30 as a mixing chamber 30d.

[0200] In one embodiment, please refer to Figures 6 to 26 The garment handling 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. For example, 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 located within the receiving cavity 30e.

[0201] 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.

[0202] 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.

[0203] In some embodiments, the filter plate 160 may be generally flat. The filter plate 160 has a simple structure and is easy to manufacture.

[0204] In some embodiments, the nozzle 130 and the detergent dispenser 30 are separate structures. That is, the nozzle 130 and the detergent dispenser 30 are manufactured independently. The mixing chamber 30d may be located upstream of the liquid outlet channel 130b. For example, the detergent dispenser 30 may be located above the cylinder assembly 10, and the nozzle 130 may be disposed on the door seal ring 60.

[0205] In some embodiments, please refer to Figures 3 to 12 The garment processing 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 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.

[0206] In some embodiments, please refer to Figures 3 to 12The garment processing device includes a third conduit 50, one end of which is connected to a water source. The third conduit 50 is connected to a mixing space 20a to direct water from the water source into the mixing space 20a. For example, the third conduit 50 is connected to a tubing 131. In this embodiment, the space within the third conduit 50 defines a portion of a second water passage 50A.

[0207] 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.

[0208] The second pipe 42 mentioned above can be a single pipe or a combination of multiple pipe sections; there is no limitation on this.

[0209] The aforementioned third pipe 50 can be a single, complete pipe or a series of connected pipe segments; no restrictions are imposed here.

[0210] 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.

[0211] 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.

[0212] 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.

[0213] For example, such as Figure 1 As shown, the garment processing equipment also includes a water outlet pipe 70, which connects to a second drain outlet 30a and a water inlet.

[0214] In some embodiments, please refer 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.

[0215] In some embodiments, at least a portion of the detergent dispenser 30 is formed on the workbench 80.

[0216] 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.

[0217] 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.

[0218] 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.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] In some embodiments, please refer 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. In this way, reusing the worktable 80 as part of the detergent dispenser 30 and the spray nozzle 130 reduces the number of parts, reduces material usage, and lowers material costs.

[0223] In one embodiment, please refer to Figures 13 to 26The workbench 80 has a suction port 80b on its surface facing the laundry dispensing port 80a. The suction port 80b communicates with the cavity of the detergent dispenser 30, and the dispenser box 140 enters and exits the detergent dispenser 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 dispenser 30 through the suction port 80b; when detergent addition is complete, the dispenser box 140 can be pushed into the detergent dispenser 30 through the suction port 80b. During the washing process, the detergent and other fluids in the detergent dispensing 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 laundry 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 laundry processing chamber through the suction port 80b.

[0224] In some embodiments, please refer to Figures 17 to 26 A portion of the pumping port 80b of the workbench 80 can form a second drain port 30a.
