Description

Technical Field

[0001] The present application relates to the technical field of clothing processing, and in particular to a nozzle and clothing processing equipment. Background Art

[0002] This section is intended to provide a background or context for the embodiments of the present application. No description herein is admitted to be prior art by virtue of its inclusion in this section.

[0003] In the prior art, laundry processing equipment includes a laundry processing chamber and a pipeline. The pipeline delivers a detergent solution into the laundry processing chamber, thereby adding detergent to the laundry processing chamber to participate in the laundry processing. However, detergent, especially washing powder, often does not dissolve fully and mixes unevenly with the water flow, resulting in insufficient detergent utilization, poor cleaning results, and a poor user experience. Utility Model Content

[0004] In view of this, the present application hopes to provide a nozzle and a clothing processing device that can promote the dissolution of detergent.

[0005] The present invention provides a nozzle, which has:

[0006] Liquid flow channel;

[0007] A liquid outlet channel, at least one of the liquid flow channel and the liquid outlet channel is used to transport a detergent mixed solution; at least one of the liquid flow channel and the liquid outlet channel is provided with a pressurizing structure and / or a turbulent structure, the pressurizing structure is used to increase the flow rate of the fluid, and the turbulent structure is used to provide a circumferential velocity component to the fluid.

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

[0009] In some embodiments, the turbulent flow structure includes one or more spiral blades, and the spiral blades are used to guide the fluid to move in a spiral manner.

[0010] In some embodiments, the pressurizing structure and the turbulent flow structure are disposed in the same channel, and the pressurizing structure is located downstream of the turbulent flow 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 projections of the axis of the first water outlet end and the axis of the second water outlet end in a horizontal plane intersect.

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

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

[0014] In some embodiments, the spray head includes a shell and a cannula, the shell forms the liquid outlet channel and the mixing space, the cannula forms the liquid flow channel, and at least a portion of the cannula is inserted into the mixing space.

[0015] The present application also provides a clothes processing device, including:

[0016] laundry processing chamber;

[0017] In any one of the above-mentioned nozzles, the liquid flow channel and the liquid outlet channel both transport fluid into the clothing processing chamber.

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

[0019] The clothes processing device includes a workbench, and the nozzle is arranged on the workbench.

[0020] The nozzle provided in the embodiment of the present application has a pressurized structure to increase the speed of the fluid, and a turbulent structure to provide a circumferential velocity component to the fluid. The turbulent structure can also make the fluid diverge in a conical shape. The fluid transported by the liquid outlet channel and the fluid transported by the liquid flow channel intersect and mix. The mixed fluid enters the clothing processing chamber and participates in clothing processing. There is a flow rate 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 pressurized structure and / or the turbulent structure, and the flow rate of the fluid in the liquid flow channel is greater than the flow rate of the fluid in the liquid outlet channel. The flow rates of the two fluids are one fast and the other slow, and the one with a faster flow rate can impact and disturb the one with a slower flow rate, so that the detergent can be better mixed when the two fluids intersect, further promoting the dissolution of the detergent. In other words, the nozzle can promote the mixing of the solution and can also make the fluid diverge in a conical shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other. The detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0050] It should be noted that, in the embodiments of the present application, down refers to the direction of the ground, and up is opposite to down; front refers to the direction toward the user, and back is opposite to front; left is the side where the left hand of the user is located when the user is in front of the clothing processing device, and right is opposite to left; the up and down directions, the front and back directions, and the left and right directions are perpendicular to each other. In the embodiments of the present application, the orientation or positional relationship of "up", "down", "front", "back", "left", and "right" is based on the orientation or positional relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0051] In the embodiments of the present application, "a plurality" refers to a number including two or more, and "at least two" refers to a number including two or more.

[0052] The functions of the clothes processing device provided in the embodiments of the present application are not limited. For example, the clothes processing device may have a drying function in addition to a washing function. The drying function may be used to dry clothes.

[0053] The clothes treating apparatus may be a drum-type clothes treating apparatus or a pulsator-type clothes treating apparatus, such as a drum washing machine or a pulsator washing machine.

[0054] The clothes treating device comprises a clothes treating chamber, and the clothes treating chamber is used for placing clothes.

[0055] The laundry processing chamber of a drum type laundry processing apparatus rotates around an axis extending in a horizontal direction or an inclined direction. The laundry processing chamber of a pulsator type laundry processing apparatus rotates around an axis extending in a vertical direction.

[0056] The axis in the inclined direction refers to the axis of the laundry processing chamber being obliquely intersected with the horizontal direction.

[0057] See also Figure 1 The laundry processing apparatus may include a drum assembly 10. The axis of the drum assembly 10 may extend in an up-down direction, a horizontal direction, or an inclined direction. The interior space of the drum assembly 10 may be at least a portion of a laundry processing chamber.

[0058] For some examples, see Figure 1 and Figure 2 The laundry processing device may include a door seal 60. The axis of the drum assembly 10 extends horizontally or obliquely. The door seal 60 may be provided at the front end of the drum assembly 10. The laundry processing device in this embodiment is also referred to as a drum type laundry processing device, such as a drum washing machine.

[0059] For some examples, see Figure 13 The laundry processing device includes a workbench 80. The axis of the drum assembly 10 extends in the vertical direction. The workbench 80 can be arranged above the drum assembly 10. The workbench 80 constitutes the exterior surface of the laundry processing device. The laundry processing device in this embodiment is also called a pulsator laundry processing device, such as a pulsator washing machine.

[0060] See also Figure 13 The workbench 80 has a clothing delivery port 80a, which passes through two surfaces of the workbench 80 in the upper and lower directions, and is communicated with the clothing processing chamber.

[0061] In some embodiments, the drum assembly 10 includes a rotatable inner drum having an access opening. The access opening can face upward or forward. The inner drum can be used to hold a load such as clothing. The inner drum can rotate, for example, so that clothing, liquid, and detergent rotate with the inner drum. This allows the clothing to continuously change position within the inner drum, and fluids such as liquid and detergent to change direction as they flow.

[0062] For the pulsator type clothes processing device, the take-in and put-out opening faces upwards. The user can put clothes into or take out the inner drum from above through the clothes putting-in opening 80a and the take-in and put-out opening.

[0063] For drum-type clothes processing equipment, the access opening faces forward. Users put clothes into or take out clothes from the front through the space enclosed by the door sealing ring 60 and the access opening.

[0064] In some embodiments, the inner cylinder may be substantially in the shape of a hollow cylinder.

[0065] For some examples, see Figure 1 The barrel assembly 10 includes an outer barrel 11, and the inner barrel can be arranged in the outer barrel 11. The outer barrel 11 can be used to hold water for washing clothes, and the inner barrel is used to hold clothes.

[0066] In this embodiment, the outer tub 11 holds water, and the inner tub can also be called a perforated inner tub. The space within the inner tub forms at least a portion of the laundry treatment chamber. Fluid can flow between the space between the outer tub 11 and the inner tub and the space within the inner tub through the flow holes in the inner tub.

[0067] For some examples, see Figure 1 , the outer barrel 11 can be roughly in the shape of a hollow cylinder.

[0068] In some embodiments, the inner cylinder holds water by itself and can also be called a non-porous inner cylinder. An outer cylinder 11 can be provided outside the inner cylinder or not.

[0069] It is understood that in some embodiments, the drum assembly 10 may only include an inner drum, without the outer tub 11. In such embodiments, the inner drum is a non-porous inner drum capable of holding water. The inner drum may be a single drum structure. In other words, the laundry processing device may only include the inner drum.

[0070] In some embodiments, the clothes treating apparatus includes a housing, and the drum assembly 10 is disposed in the housing.

[0071] In some embodiments, the box may be substantially in the shape of a hexahedron, for example, a cube or a cuboid.

[0072] In some embodiments, the laundry processing apparatus includes a door configured to selectively open or close an opening of a housing. The housing is provided with an opening communicating with the interior space of the drum assembly 10. The axis of the drum assembly 10 extends horizontally or obliquely. The door seal 60 can be configured to seal the gap between the drum assembly 10 and the housing opening. The interconnected space formed by the door, the door seal 60, and the interior of the drum assembly 10 constitutes a laundry processing chamber. In other words, for a drum-type laundry processing apparatus, the interconnected space formed by the door, the door seal 60, and the interior of the drum assembly 10 constitutes the laundry processing chamber.

[0073] In some embodiments, the laundry processing apparatus includes a door, the axis of the drum assembly 10 extends in a vertical direction, the workbench 80 can be disposed within the housing, and the door can selectively open or close the laundry loading port 80a. In other words, for a pulsator-type laundry processing apparatus, the space within the inner drum can constitute at least a portion of the laundry processing chamber, the workbench 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 arranged at the upper part of the box. It is understood that, with the plane perpendicular to the front-back direction as the projection plane and the straight line extending in the horizontal direction and bisecting the projection of the box as the bisector, 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 a control panel, which can be used to control the operation of the clothing processing device.

[0076] The embodiment of the present application provides a nozzle 130, which is used in a clothes processing device. Figures 10 to 26 The nozzle 130 has a liquid flow channel 130a and a liquid outlet 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 velocity 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, the pressurizing structure 120 and the turbulent structure 21 are provided. The pressurizing structure 120 is used to increase the flow rate of the fluid in the liquid outlet channel 130b, and the turbulent 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, the pressurizing structure 120 and the turbulent structure 21 are provided. The pressurizing structure 120 is used to increase the flow velocity of the fluid in the liquid flow channel 130a, and the turbulent structure 21 is used to provide a circumferential velocity component to the fluid in the liquid flow channel 130a.

[0079] Taking the example of a liquid flow channel 130a provided with a turbulent flow structure 21, the aforementioned provision of a circumferential velocity component refers to the fact that the fluid in the liquid flow channel 130a, after passing through the turbulent flow structure 21, has a velocity component in the circumferential direction of the liquid flow channel 130a that is non-zero, and the circumferential direction of the liquid flow channel 130a surrounds the extension direction of the liquid flow channel 130a. After passing through the turbulent flow 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. The turbulent flow structure 21 can also increase the flow rate of the fluid by limiting the flow area of ​​the liquid flow channel 130a in which it is located.

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

[0081] At least one of the liquid flow channel 130a and the liquid outlet channel 130b is provided with a pressurizing structure 120 and / or a turbulent flow structure 21 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 pressurizing structure 120 and the turbulent flow structure 21.

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

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

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

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

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

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

[0088] The above examples exemplify the embodiments in which the pressurizing structure 120 and the turbulent flow structure 21 are provided in the liquid flow channel 130a and the liquid outlet channel 130b. Those skilled in the art can obtain other embodiments based on the above examples, which are not listed here one by one.

[0089] At least one of the liquid flow channel 130a and the liquid outlet channel 130b is used to transport the detergent mixed solution. For example, both the liquid flow channel 130a and the liquid outlet channel 130b may transport the detergent mixed solution. For another example, the liquid flow channel 130a transports the detergent mixed solution, while the liquid outlet channel 130b transports other fluids. For another example, the liquid outlet channel 130b transports the detergent mixed solution, while the liquid flow channel 130a transports other fluids.

[0090] It should be noted that the detergent mixed solution mentioned in this application is merely for convenience of description and refers to a mixed solution in which detergent is dissolved. Its mass percentage concentration is not limited, and the detergent mixed solution is not limited to a solution in which the detergent is completely dissolved. In some embodiments, the detergent mixed solution can be a user-added detergent stock solution. In other embodiments, the detergent mixed solution can be a mixture of detergent and water from a water source.

[0091] The functions of detergents are not limited. For example, the functions of detergents include but are not limited to cleaning, softening or adding fragrance.

[0092] The type of detergent is not limited, and the detergent includes but is not limited to detergent, softener and / or fragrance, etc.

[0093] The form of the detergent is not limited, and it can be powdered laundry detergent or flowable laundry liquid.

[0094] Other fluids include but are not limited to water or solutions with other care ingredients added, etc. Water includes but is not limited to tap water or recycled water from a water source.

[0095] It can be understood that the liquid flow channel 130a and the liquid outlet channel 130b are both used for circulating fluids, and the detergent mixed solution and water are all fluids.

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

[0097] In the nozzle provided by the embodiment of the present application, the pressurizing structure 120 increases the speed of the fluid, and the turbulent structure 21 provides a circumferential velocity component to the fluid. The turbulent structure 21 can also cause the fluid to diverge in a conical shape. The fluid transported by the liquid outlet channel 130b and the fluid transported by the liquid flow channel 130a intersect and mix. The mixed fluid enters the clothing treatment chamber and participates in the clothing treatment. There is a flow rate difference between the fluid in the liquid outlet channel 130b and the fluid in the liquid flow channel 130a. For example, the fluid in the liquid flow channel 130a is accelerated by the pressurizing structure 120 and / or the turbulent structure 21, and the flow rate of the fluid in the liquid flow channel 130a is greater than the flow rate of the fluid in the liquid outlet channel 130b. The flow rates of the two fluids are fast and slow, and the faster flow rate can impact and disturb the slower flow rate, so that the detergent can be better mixed when the two fluids intersect, further promoting the dissolution of the detergent. In other words, the nozzle 130 can promote the mixing of the solution and also cause the fluid to diverge in a conical shape.

[0098] In one embodiment, the liquid flow channel 130a transports water, and the liquid outlet channel 130b transports a detergent mixed solution. The water transported by the liquid flow channel 130a can further promote the dissolution of detergent, such as washing powder, in the liquid outlet channel 130b.

[0099] The present application embodiment provides a clothes processing device. Figure 2 、 Figure 10 、 Figure 12 、 Figure 15 as well as Figure 26 The laundry processing apparatus includes a laundry processing chamber and a nozzle according to any embodiment of the present application. The liquid flow channel 130a and the liquid outlet channel 130b both deliver fluid to the laundry processing chamber. The fluid output by the liquid flow channel 130a and the fluid output by the liquid outlet channel 130b can meet in mid-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 laundry.

[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 outlet channel 130b is defined as the first outlet end 40Aa. The following description assumes that the liquid flow channel 130a is provided with the pressurizing structure 120 and / or the turbulent flow structure 21.

[0101] In one embodiment, please refer to Figure 12 and Figure 26 Liquid outlet channel 130b has a first outlet end 40Aa, liquid flow channel 130a has a second outlet end 50Aa, and the projections of the axis of the first outlet end 40Aa and the axis of the second outlet end 50Aa on a horizontal plane intersect. In other words, with the horizontal plane as the projection plane, the projections of the axis of the first outlet end 40Aa and the axis of the second outlet end 50Aa intersect.

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

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

[0104] The flow cross section is a cross section 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 to each other, the flow cross section is a flat surface.

[0105] A pressurized structure 120 and / or a turbulent flow structure 21 are provided in the liquid flow channel 130a, and the flow rate of the second water outlet end 50Aa is greater than the flow rate of the first water outlet end 40Aa. On the one hand, there is a flow rate difference between the fluid discharged from the liquid flow channel 130a and the fluid discharged from the liquid outlet channel 130b. The flow rate of the second water outlet end 50Aa is relatively large, which can increase the impact force of the fluid. The faster flow rate can impact and disturb the slower flow rate, which can make the detergent mix better when the two fluids meet, further promoting the dissolution of the detergent. On the other hand, the flow rate of the second water outlet end 50Aa is relatively large, which can generate negative pressure in the surrounding area, so that the fluid at the first water outlet end 40Aa is sucked in under the action of this negative pressure, thereby improving the mixing effect.

[0106] In this embodiment, both the liquid outlet channel 130b and the liquid flow channel 130a circulate fluid. The fluid circulated in the liquid outlet channel 130b is ejected roughly along the axis of the first water outlet end 40Aa, and the fluid circulated in the liquid flow channel 130a is ejected roughly along the axis of the second water outlet end 50Aa. The projections of the axis of the first water outlet end 40Aa and the axis of the second water outlet end 50Aa in the horizontal plane intersect. In this way, the fluid ejected from the first water outlet end 40Aa and the fluid ejected from the second water outlet end 50Aa can converge. When the two fluids converge, the two fluids mix and impact, which can further promote the dissolution of detergent, which is beneficial for delivering 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 defines a mixing space 20a. Both the liquid flow channel 130a and the liquid outlet channel 130b are connected to the mixing space 20a. In other words, both the first outlet end 40Aa and the second 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 enter the mixing space 20a, where they intersect 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 structure 21 provides a circumferential velocity component to the fluid in the liquid flow channel 130a. There is a flow rate difference between the fluid in the liquid outlet channel 130b and the fluid in the liquid flow channel 130a. The flow rates of the two fluids entering the mixing space 20a are one fast and one slow. The one with a faster flow rate can impact and disturb the one with a slower flow rate, thereby improving the mixing effect and allowing detergents such as laundry detergent to be more fully dissolved.

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

[0110] It is understood that the turbulent flow structure 21 can also increase the flow rate of the fluid by limiting the flow area of ​​the liquid flow channel 130a in which it is located. In this way, the speed difference between the two fluids entering the mixing space 20a is further increased, further promoting the dissolution of the detergent.

[0111] In one embodiment, the fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa can intersect in the air, and the intersection area can be located in the clothing processing chamber. The nozzle may not have a mixing space 20a, and the fluid discharged from the second water outlet 50Aa and the fluid discharged from the first water outlet 40Aa directly intersect in the air, and the intersection area is located in the clothing 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 detergents such as washing powder. Since the intersection area is located in the clothing processing chamber, the distance from the intersection area to the mixed fluid of the first water channel 40A and the second water channel 50A to the time when it is dropped onto the clothing to be processed can be shortened, reducing the degree of bubble breaking, which is conducive to the addition of foamy detergent to the clothing to be processed, 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 connected to the mixing space 20a. The liquid outlet 20ab is used to discharge the fluid in the mixing space 20a. It is understood that the liquid outlet 20ab can pass through the outer surface of the physical structure where it is located.

[0113] After passing through the turbulent structure 21, the fluid in the liquid flow channel 130a generates a multi-directional composite motion, including circumferential and forward motions, thereby better mixing with the fluid in the mixing space 20a and improving mixing efficiency. It also enables the fluid ejected from the liquid outlet 20ab to disperse in a roughly conical shape, extending the radiation range and enhancing the visual effect. The pressurizing structure 120 accelerates the fluid in the liquid flow channel 130a, and the turbulent structure 21 provides a circumferential velocity component to the fluid in the liquid flow channel 130a. The fluid transported by the liquid outlet channel 130b and the fluid transported by the liquid flow channel 130a meet and mix in the mixing space 20a. The mixed fluid is then discharged from the liquid outlet 20ab and enters the clothing processing chamber, participating in the clothing processing.

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

[0115] In this embodiment, the second water outlet end 50Aa is directed toward the liquid outlet 20ab, and the liquid outlet 20ab is downstream of the flow direction of the fluid discharged from the second water outlet end 50Aa, so that the flow discharged from the second water outlet end 50Aa flows toward the location of the liquid outlet 20ab. The fluid from the second water outlet end 50Aa can flow quickly to the liquid outlet 20ab and be discharged without changing the flow direction as much as possible.

[0116] In one embodiment, please refer to Figure 12 、 Figure 19 as well as Figure 26 With the plane of liquid outlet 20ab as the projection plane, the projection of second water outlet end 50Aa is within the projection range of liquid outlet 20ab. For example, the flow area of ​​liquid outlet 20ab can be larger than the flow area of ​​second water outlet end 50Aa. This prevents the water outlet end of liquid flow channel 130a from misaligning with liquid outlet 20ab, which could cause 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] Direct communication between liquid outlet 20ab and the laundry processing chamber means that liquid outlet 20ab opens into the laundry processing chamber, and fluid from liquid outlet 20ab enters the laundry processing chamber directly. There is no intermediate channel between liquid outlet 20ab and the laundry processing chamber, such as a transfer pipe or other fluid-carrying member. Fluid from liquid outlet 20ab does not need to be guided through an intermediate channel; instead, it is directly discharged into the laundry processing chamber under the influence of its own gravity and flow rate.

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

[0120] In one embodiment, the liquid outlet 20ab can also be connected to a transfer channel. That is, the fluid from the liquid outlet 20ab flows through the transfer channel before entering the clothing treatment chamber. The transfer channel can be used to change the flow direction and / or shape of the fluid, allowing the fluid to be sprayed toward specific locations on clothing and / or in a specific shape.

[0121] In one embodiment, the liquid outlet 20ab is located in the laundry processing chamber. For example, the liquid outlet 20ab extends radially inward of the door seal 60. This brings the liquid outlet 20ab closer to the laundry in the laundry 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 distal end of the pressurizing structure 120 extends into the mixing space 20a. This extends into the mixing space 20a to accelerate the fluid entering the mixing space 20a. The fluid, accelerated by the pressurizing structure 120, enters the mixing space 20a through the distal end of the pressurizing structure 120. The increased impact force of the accelerated fluid enhances agitation within the mixing space 20a, improving the mixing effect and the cleaning efficiency.

[0123] In one embodiment, please refer to Figure 12 and Figure 20 The pressurizing structure 120 includes a reduced diameter section 22. The reduced diameter section 22 increases the flow rate at the outlet end of the liquid flow channel 130a and / or the outlet end of the liquid outlet channel 130b where the pressurizing structure 120 is located. For example, in the case of liquid flow channel 130a being provided with the pressurizing structure 120, the reduced diameter section 22 increases the flow rate at the second outlet end 50Aa of the liquid flow channel 130a. For example, in the case of liquid outlet channel 130b being provided with the pressurizing structure 120, the reduced diameter section 22 increases the flow rate at the first outlet end 40Aa of the liquid outlet channel 130b.

[0124] In this embodiment, the reduced diameter section 22 refers to a section along the flow direction where the fluid's flow area is reduced. By limiting the flow area, the reduced diameter section 22 increases the fluid's impact force, achieving a good mixing effect. For example, in the case of the fluid channel 130a equipped with the pressurizing structure 120, the reduced diameter section 22 enables the second water outlet 50Aa to have a higher ejection velocity, generating a significant negative pressure over 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, enhancing the mixing effect.

[0125] In some embodiments, the pressurizing structure 120 includes a powered pressurizing mechanism. This refers to a mechanism that uses a power source to increase fluid pressure and thereby increase flow rate. The power source includes, but is not limited to, electricity or other energy sources. This powered pressurizing mechanism can actively increase fluid flow rate, providing a higher degree of automation compared to the passive increase in fluid flow rate achieved by the reduced diameter section 22.

[0126] The type of the power pressurizing mechanism is not limited. For example, the power pressurizing mechanism includes but is not limited to a water pump, a peristaltic pump, and the like.

[0127] In some embodiments, the end of the pressurizing structure 120 forms the second water outlet 50Aa. In other words, the fluid in the second waterway 50A is directly ejected from the end of the pressurizing structure 120, such as the reduced diameter section 22.

[0128] For some examples, see Figure 12 and Figure 20 The end of the pressurizing structure 120 is connected to a constant diameter section 23 and / or an expanded diameter section, and the constant diameter section 23 and / or the expanded diameter section forms a second water outlet end 50Aa.

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

[0130] For another example, the end of the pressurizing structure 120 is connected to an expanded diameter section, which forms the second water outlet end 50Aa.

[0131] For another example, the end of the pressurizing structure 120 is connected to a constant diameter section 23 and an expanded diameter section, and either the constant diameter section 23 or the expanded diameter section forms the second water outlet end 50Aa.

[0132] The constant diameter section 23 means that the flow area of ​​the fluid in the constant diameter section 23 remains substantially unchanged along the flow direction of the fluid.

[0133] The expanded diameter section refers to the section where the flow area of ​​the fluid becomes larger along the flow direction of the fluid.

[0134] In this embodiment, the fluid in the second waterway 50A is ejected directly from the constant diameter section 23 and / or the expanded diameter section into the mixing space 20a. The fluid, accelerated by the pressurizing structure 120, then flows through the constant diameter section 23 and / or the expanded diameter section, where it can diverge into the mixing space 20a at a relatively high speed in a conical shape.

[0135] In some embodiments, the length of the constant diameter section 23 extending along the second waterway 50A is less than or equal to the length of the reduced diameter section 22 extending along the second waterway 50A. Because the longer the flow path of a fluid, the more significant its energy loss is, limiting the length of the constant diameter section 23 can reduce the loss of impact force after the fluid flows out of the reduced diameter section 22.

[0136] In some embodiments, the length of the expanded section along the second waterway 50A is less than or equal to the length of the reduced section 22 along the second waterway 50A. Because a longer fluid flow path results in greater energy loss, limiting the length of the expanded section can reduce the impact force loss after the fluid flows out of the reduced section 22.

[0137] In one embodiment, please refer to Figure 12 and Figure 20 The turbulence structure 21 includes one or more spiral blades, which are used to guide the spiral motion of the fluid. Taking the liquid flow channel 130a provided with the turbulence structure 21 as an example, the spiral blades are used to guide the spiral motion of the fluid in the liquid flow channel 130a. The spiral blades are blades with a helical shape, and the blades extend in a spiral direction. After the fluid passes through the spiral blades, it exhibits a spiral motion with a circumferential velocity component. The spiral blades have a simple structure, a good turbulence effect on the fluid, and low resistance, thereby reducing energy loss when the fluid passes through.

[0138] Exemplarily, the turbulent flow structure 21 includes one or more spiral blades, which divide at least a partial length of the second water channel 50A where the spiral blades are located into a plurality of sub-flow channels.

[0139] The above-mentioned multiple refers to the number of spiral blades being multiple, which can be two, three or more, that is, the number of heads of the spiral line is not less than two, and does not limit the number of turns of the spiral line.

[0140] For some examples, see Figure 12 and Figure 20 The outer edge of the spiral blade along the spiral direction is connected to the inner wall of the liquid flow channel 130a, and the inner edge of the spiral blade along the spiral direction is spaced apart from the inner wall of the liquid flow channel 130a. In other words, there is a gap between the inner edge of the spiral blade and the inner wall of the liquid flow channel 130a. In this way, the inner wall of the liquid flow channel 130a provides connection support for the spiral blade.

[0141] In some embodiments, the outer edge of the spiral blade along the spiral direction is connected to the inner wall of the liquid outlet channel 130b, and the inner edge of the spiral blade along the spiral direction is spaced apart from the inner wall of the liquid outlet channel 130b. In other words, there is a gap between the inner edge of the spiral blade and the inner wall of the liquid outlet channel 130b. In this way, the inner wall of the liquid outlet channel 130b provides connection support for the spiral 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, and the pressurizing structure 120 is located downstream of the turbulent flow structure 21. The channel is either the liquid flow channel 130a or the liquid outlet channel 130b. For example, the pressurizing structure 120 and the turbulent flow structure 21 are disposed in the same liquid flow channel 130a. In another example, the pressurizing structure 120 and the turbulent flow structure 21 are 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 diameter-reducing section 22 in sequence, and then is ejected into the laundry processing chamber in 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 liquid outlet 20ab and the pressurizing structure 120. With this design, the fluid path between the turbulent structure 21 and the pressurizing structure 120 is greater than the fluid path between the pressurizing structure 120 and the liquid outlet 20ab. The fluid can be effectively accelerated by the turbulent structure 21 and the pressurizing structure 120 and can be discharged from the mixing space 20a in a timely manner, reducing losses during the flow process.

[0145] In one embodiment, please refer to Figures 10 to 12 The nozzle 130 includes a housing 132 and a cannula 131. The housing 132 defines a liquid outlet channel 130b and a mixing space 20a. The cannula 131 defines a liquid flow channel 130a. At least a portion of the cannula 131 is inserted into the mixing space 20a. Specifically, the second water outlet 50Aa is formed on the cannula 131. Exemplarily, the end of the cannula 131 located within the mixing space 20a is the second water outlet 50Aa. The nozzle 130 has a simple structure and is easy to manufacture.

[0146] In one embodiment, please refer to Figures 10 to 12 The end of the cannula 131 facing the first direction is the second outlet end 50Aa. The first outlet end 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 outlet end 40Aa flows generally in the first direction, while the fluid discharged from the second outlet end 50Aa flows generally in the second direction. The two fluids intersect and mix in the mixing space 20a.

[0147] In one embodiment, please refer to Figures 10 to 12 The housing 132 is formed with a liquid outlet 20ab. Exemplarily, the liquid outlet 20ab is formed on a side wall of the housing 132 along the first direction. The fluid in the mixing space 20a is sprayed out of the spray head 130 through the liquid outlet 20ab.

[0148] For example, see Figures 10 to 12 Sprinkler 130 also includes a connector pipe 133 connected to housing 132. Connector pipe 133 communicates with the end of liquid outlet channel 130b distal from first water outlet end 40Aa. The space within connector pipe 133 forms part of first waterway 40A. Connector pipe 133 connects to second pipe 42. Second pipe 42 delivers fluid to sprinkler 130 via connector pipe 133.

[0149] In one embodiment, please refer to Figure 2 、 Figures 10 to 12 The clothing processing device includes a door seal 60, and the nozzle 130 is provided on the door seal 60. The door seal 60 not only provides an installation position for the nozzle 130, but also allows the detergent mixed solution sprayed by the nozzle 130 to be closer to the clothing processing chamber.

[0150] In one embodiment, please refer to Figure 2 、 Figures 10 to 12 The space enclosed by the door seal 60 is part of the laundry processing chamber, and the liquid outlet 20ab extends radially inwardly of the door seal 60. In other words, the laundry processing apparatus may be a drum-type laundry processing apparatus. Fluid discharged from the liquid outlet 20ab can directly enter the space enclosed by the door seal 60, and thus directly enter the laundry processing chamber.

[0151] It should be noted that the extending direction of the axis of the door sealing ring 60 is consistent with the extending direction of the axis of the cylinder assembly 10 , and the axis of the door sealing ring 60 can extend in a horizontal direction or an inclined direction.

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

[0153] The nozzle 130 and the workbench 80 may be separate structures. In other words, the nozzle 130 and the workbench 80 are manufactured separately and then assembled together through a detachable connection or a non-detachable connection.

[0154] At least a portion of the nozzle head 130 is formed on the workbench 80, which means that at least a portion of the nozzle head 130 is formed by the physical structure of the workbench 80. Exemplarily, at least a portion of the nozzle head 130 is integrally formed with at least a portion of the physical structure of the workbench 80. For example, at least a portion of the nozzle head 130 is integrally injection molded with at least a portion of the physical structure of the workbench 80.

[0155] In other words, part of the structure of the workbench 80 is an integral part of the nozzle 130. In this way, the workbench 80 is reused as a part of the nozzle 130, which can reduce the number of parts, reduce the material used, and reduce the material cost.

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

[0157] In this embodiment, the partition member 150 and the workbench 80 are used to jointly define the liquid outlet channel 130 b , which can reduce the number of pipes arranged on the workbench 80 , simplify the pipe layout, and reduce the manufacturing difficulty.

[0158] The partition member 150 and the workbench 80 can be connected in a detachable or non-detachable manner. In some embodiments, the partition member 150 and the workbench 80 can be welded or bonded. In some embodiments, the partition member 150 and the workbench 80 can be connected by snapping, screwing, or bolting.

[0159] The connection between the partition member 150 and the workbench 80 can be sealed. In this way, fluid leakage at the connection between the partition member 150 and the workbench 80 is avoided.

[0160] For example, the connection between the partition member 150 and the workbench 80 can be sealed by welding, gluing, or by a sealant. The sealant can be a flexible structure that utilizes elastic deformation to seal the gap between the partition member 150 and the workbench 80. For example, the sealant can be a flexible structure made of rubber and / or silicone.

[0161] In some embodiments, the workbench 80 forms an open slot opening downward, and the partition member 150 closes the downward opening of the open slot to form the liquid outlet channel 130 b of the spray head 130 and the mixing chamber 30 d of the detergent box 30 .

[0162] For some examples, see Figures 22 to 26 , the part of the workbench 80 is concave to form the liquid outlet channel 130b. In other words, the partition plate 150 can be omitted, but the workbench 80 can be fully utilized to form the liquid outlet channel 130b for the fluid to circulate, so that parts can be saved and costs can be reduced.

[0163] In one embodiment, please refer to Figure 19 、 Figure 23 and Figure 26 The workbench 80 defines a liquid outlet 20ab communicating with the mixing space 20a. The mixing space 20a is located between the second water outlet 50Aa and the liquid outlet 20ab. Liquid outlet 20ab is formed on the workbench 80 to facilitate downward spraying of fluid discharged from the liquid outlet 20ab into the laundry 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] For some examples, see Figure 18 and Figure 22 The liquid outlet 20ab is formed on the surface of the workbench 80 facing the clothing loading port 80a. In this way, it is possible to avoid as much as possible that the structure on the workbench 80 blocks the liquid outlet 20ab from discharging fluid.

[0165] In one embodiment, please refer to Figures 13 to 26 The nozzle 130 includes a cannula 131, which forms a liquid flow channel 130a. The workbench 80 forms a liquid outlet channel 130b. The cannula 131 is inserted into the workbench 80. In other words, the workbench 80 is formed with a socket, into which the cannula 131 is inserted. This design uses the workbench 80 to provide a mounting location for the cannula 131, simplifying the installation process and improving production efficiency. The cannula 131 forms the liquid flow channel 130a, resulting in a simple structure, and the workbench 80 provides a mounting location for the cannula 131.

[0166] In one embodiment, the partition member 150 forms an insertion hole, and the insertion tube 131 is inserted into the insertion hole.

[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 that utilizes elastic deformation to seal the gap at the connection between the liquid flow channel 130a and the liquid outlet channel 130b. For example, the sealing structure utilizes elastic deformation to seal the gap between the cannula 131 and the insertion hole. For example, 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 cannula 131 is inserted into the liquid outlet channel 130b. The at least partial insertion of the cannula 131 into the liquid outlet channel 130b can be done by partially inserting the cannula 131 into the liquid outlet channel 130b or by fully inserting the cannula 131 into the liquid outlet channel 130b. The partial insertion of the cannula 131 into the liquid outlet channel 130b facilitates connection of the portion of the cannula 131 outside the liquid outlet channel 130b to other pipes, valve ports, and the like.

[0170] In some embodiments, the water inlet end of the cannula 131 is connected to a water supply port of the water inlet valve 90. In this way, the water inlet valve 90 can supply water to the cannula 131.

[0171] See also Figures 3 to 26 The laundry processing device 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 to circulate the detergent mixed 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 a mixed detergent solution. For another example, the first water channel 40A is used to circulate a mixed detergent solution, and the second water channel 50A is used to circulate other fluids. For another example, the second water channel 50A is used to circulate a mixed detergent solution, and the first water channel 40A is used to circulate other fluids.

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

[0174] In some embodiments, the water inlet end of the first water channel 40A may be connected to a water source, and the water inlet end of the second water channel 50A may be connected to a water source.

[0175] It should be noted that the water source in the embodiment of the present application refers to the water source that supplies water to the first water channel 40A and / or the second water channel 50A, such as tap water; it can also be the internal water source of the clothing processing equipment, such as circulating water.

[0176] In one embodiment, please refer to Figure 3 、 Figure 5 and Figure 13 The laundry processing apparatus includes a water inlet valve 90, which is connected to a water source, such as a tap water pipe. The first water channel 40A and the second water channel 50A can be connected to different water inlet valves 90, or they can be connected to the same water inlet valve 90, without limitation. As an optional embodiment, the laundry processing apparatus includes a circulation pump, with one of the first water channel 40A and the second water channel 50A connected to the water inlet valve 90, and the other connected to the circulation pump of the laundry processing apparatus.

[0177] In some embodiments, the water inlet valve 90 has at least two water inlets, with the first water channel 40A and the second water channel 50A each connected to one of the water inlets. A water source supplies water to the laundry processing apparatus through the water inlet valve 90 . The first water channel 40A and the second water channel 50A each connect to one of the water inlets. The water flow rates at the different water inlets can differ, thereby increasing the flow rate difference between the first water channel 40A and the second water channel 50A.

[0178] In one embodiment, the first water channel 40A is used to transport the detergent mixed solution, and the second water channel 50A is used to transport water.

[0179] In this embodiment, first water channel 40A transports a mixed detergent solution, such as a laundry liquid solution or a laundry powder solution, particularly a laundry powder solution. Because laundry powder is a powdered detergent and is more susceptible to clogging and residue than liquid laundry, second water channel 50A transports water from a source. The placement of pressurizing structure 120 and / or turbulent flow structure 21 within second water channel 50A can, to a certain extent, prevent pressurizing structure 120, turbulent flow structure 21, etc. from contacting the laundry powder.

[0180] In one embodiment, please refer to Figures 12 to 26 The fluid in the first water channel 40A is discharged through the first outlet 40Aa, and the fluid in the second water channel 50A is discharged through the second outlet 50Aa. Using the nozzle 130 to form part of the first water channel 40A and part of the second water channel 50A can reduce the number of pipes laid out in the clothing processing equipment and reduce the manufacturing difficulty.

[0181] For some examples, see Figure 3 、 Figure 9 and Figure 26 The clothing processing device includes a dispenser box 140, which forms a detergent delivery chamber 140a. The detergent delivery chamber 140a is connected to the first water channel 40A. The detergent delivery chamber 140a is a part of the first water channel 40A. The detergent delivery chamber 140a is used to hold detergent. The detergent delivery chamber 140a can be suitable for accommodating powdered laundry detergent. Of course, the detergent delivery chamber 140a can also be suitable for accommodating detergents with flow characteristics, such as laundry liquid. The detergent delivery chamber 140a is located upstream of the mixing space 20a. The water flow impacts the laundry detergent in the delivery chamber to preliminarily dissolve the laundry detergent to form a detergent mixed solution, and the detergent mixed solution then enters the mixing space 20a.

[0182] The number of detergent dispensing chambers 140a is not limited, and the number of detergent dispensing chambers 140a can be one or more. Taking multiple detergent dispensing chambers 140a as an example, the multiple detergent dispensing chambers 140a can be arranged in a direction perpendicular to the vertical direction. For example, the multiple detergent dispensing chambers 140a can be arranged in a left-right direction or a front-back direction. Each detergent dispensing chamber 140a can dispense detergents with different functions or the same function.

[0183] For example, an addition port communicating with the detergent delivery chamber 140a is formed on the upper surface of the dispenser box 140. A user can add detergent to the detergent delivery chamber 140a through the addition port from above.

[0184] For some examples, see Figures 3 to 26 The laundry treatment apparatus includes a detergent box 30, which includes a mixing chamber 30d. A dispenser box 140 includes at least two detergent delivery chambers 140a. Each detergent delivery chamber 140a is provided with a drain port 140b. At least two drain ports 140b communicate with the mixing chamber 30d. A first drain port 30b is provided on a sidewall of the mixing chamber 30d. The detergent delivery chamber 140a is located upstream of the mixing chamber 30d, and the mixing chamber 30d is located upstream of the mixing space 20a.

[0185] The discharge port 140b connects the detergent delivery chamber 140a and the mixing chamber 30d. The detergent in the detergent delivery chamber 140a flows into the mixing chamber 30d through the discharge port 140b. The mixing chamber 30d is used to hold a mixed detergent solution. The first drain port 30b is connected to the mixing chamber 30d and is used to discharge the mixed detergent solution in the mixing chamber 30d.

[0186] The detergent delivery chamber 140a, the mixing chamber 30d, and the first drain port 30b constitute a portion of the first waterway 40A. Fluid from a water source flows through the detergent delivery chamber 140a, the mixing chamber 30d, and the first drain port 30b. For example, fluid from the water source in the first waterway 40A flows through the detergent delivery chamber 140a and mixes with the detergent to form a mixed detergent solution. The mixed detergent solution then flows into the mixing chamber 30d, is discharged through the first drain port 30b, and flows into the mixing space 20a.

[0187] The second water channel 50A does not flow through the first drain port 30 b , and the detergent mixed solution conveyed by the first water channel 40A can merge with the fluid in the second water channel 50A in the mixing space 20 a .

[0188] The fluid in the mixing chamber 30d can enter the mixing space 20a and then enter the laundry processing chamber. In other words, the detergent mixed solution in the mixing chamber 30d eventually enters the laundry processing chamber to process the laundry.

[0189] In this embodiment, at least two discharge ports 140b are connected to the mixing chamber 30d, so that detergents in the multiple detergent delivery chambers 140a can all enter the mixing chamber 30d and be discharged to the clothing processing chamber through the mixing chamber 30d, and the water path is simple.

[0190] In some embodiments, the detergent delivery chamber 140a can be flushed with water so that the detergent in the detergent delivery chamber 140a enters the mixing chamber 30d. For example, the water spray port can spray water into the detergent delivery chamber 140a, and the water flow impacts the detergent in the delivery chamber to produce a detergent mixed solution, which then enters the mixing chamber 30d through the discharge port 140b.

[0191] In some embodiments, the water spray port may be formed in the detergent box 30 or the workbench 80 or the like.

[0192] In one embodiment, the water spray port can be located above the detergent delivery cavity 140a. For example, the detergent box 30 includes a lid and a body, the lid is disposed above the body and together define a cavity, a portion of which can be the mixing cavity 30d, and the lid forms the water spray port.

[0193] In one embodiment, please refer to Figures 6 to 9 ,as well as Figures 17 to 26 The detergent box 30 includes an overflow chamber 30c, which is used to receive fluid overflowing from the mixing chamber 30d. A second drain port 30a is provided on the sidewall of the overflow chamber 30c. In other words, the second drain port 30a is connected to the overflow chamber 30c and can be used to drain the mixed detergent solution in the overflow chamber 30c. Both the mixing chamber 30d and the overflow chamber 30c are part of the cavity of the detergent box 30.

[0194] In this embodiment, when the liquid level in mixing chamber 30d is below the overflow level, the fluid in mixing chamber 30d is discharged from first drain port 30b. When the liquid level in mixing chamber 30d is above the overflow level, excess fluid in mixing chamber 30d overflows into overflow chamber 30c and is discharged from second drain port 30a. In other words, the detergent mixed solution preferentially flows out of first drain port 30b, while second drain port 30a serves as a safety feature, allowing for the timely discharge of excess fluid from mixing chamber 30d.

[0195] In one embodiment, the mixing chamber 30d and the overflow chamber 30c can be distributed in the front-to-back direction, and the dimensions of the mixing chamber 30d and the overflow chamber 30c in the left-to-right direction can be larger, so that the mixing chamber 30d can be adapted to multiple detergent delivery chambers 140a to hold the fluid from the detergent delivery chamber 140a; the volume of the overflow chamber 30c is moderate to facilitate receiving 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 disposed in an accessible manner in the detergent box 30, for example, the dispenser box 140 is disposed in an accessible manner in the cavity of the detergent box 30. For example, the dispenser box 140 is disposed in a retractable manner in the detergent box 30, for example, at least a portion of the dispenser box 140 is withdrawn to the outside of the detergent box 30, and the user can dispense detergent into the detergent dispensing cavity 140a; when the dispensing is completed or when the clothes need to be washed, the dispenser box 140 can be retracted, for example, pushed into the detergent box 30.

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

[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 discharge port 140b is located above the mixing chamber 30d. The detergent mixed solution discharged from the discharge port 140b is filtered by the filter plate 160 and then enters the mixing chamber 30d.

[0199] In one embodiment, please refer to Figures 6 to 9 、 Figure 17 as well as Figure 18 The laundry treating apparatus includes a filter plate 160 having filter holes 160a. The filter plate 160 is disposed in the detergent box 30 to define a portion of the space in the detergent box 30 as a mixing chamber 30d.

[0200] In one embodiment, please refer to Figures 6 to 26 The laundry processing device includes a water retaining rib 170, the detergent box 30 has a cavity, the water retaining rib 170 extends upward from the wall of the cavity, and the filter plate 160 is arranged in the cavity. The water retaining rib 170, the filter plate 160 and part of the surface of the cavity together enclose a mixing chamber 30d. The filter plate 160 can be the upper side wall of the mixing chamber 30d, the space above the mixing chamber 30d can be the accommodating chamber 30e, and the space in front of the mixing chamber 30d can be the overflow chamber 30c. Exemplarily, the discharge port 140b can be located in the accommodating chamber 30e. The accommodating chamber 30e and the mixing chamber 30d share the filter plate 160 as a side wall. The filter hole 160a connects the accommodating chamber 30e and the mixing chamber 30d, and the discharge port 140b is connected to the accommodating chamber 30e. The portion where the discharge port 140b of the dispenser box 140 is located is located in the accommodating chamber 30e.

[0201] In this embodiment, the thickness of the filter plate 160 can be aligned with the vertical direction. The fluid discharged from the outlet 140b flows sequentially through the accommodating chamber 30e, the filter holes 160a, and the mixing chamber 30d. That is, the fluid discharged from the outlet 140b first enters the accommodating chamber 30e, is filtered by the filter plate 160, and then enters the mixing chamber 30d through the filter holes 160a. The filter plate 160 can temporarily retain particles larger than or equal to the pore size of the filter holes 160a on the upper surface of the filter plate 160, while particles smaller than the pore size of the filter holes 160a can enter the mixing chamber 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 repeatedly rinses the detergent on the upper surface of the filter plate 160, causing the detergent to dissolve again before entering the mixing chamber 30d. This improves the dissolution of the detergent, and the particles of detergent entering the clothing treatment chamber are relatively small, improving the cleaning effect.

[0202] It is understood that the pore size and shape of the filter hole 160a can be set as needed. The shape of the filter hole 160a includes but is not limited to circular, elliptical, polygonal or irregular shapes, etc. Irregular shapes refer to irregular shapes.

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

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

[0205] For some examples, see Figures 3 to 12 The laundry processing apparatus includes a first conduit 41 and a second conduit 42. One end of the first conduit 41 is connected to an external water source, for example, to the water inlet valve 90. The other end of the first conduit 41 is connected to the water inlet of the detergent box 30, for directing water into the detergent box 30. One end of the second conduit 42 is connected to the first drain outlet 30b, and the other end of the second conduit 42 is connected to the mixing space 20a, for directing fluid discharged from the first drain outlet 30b to the mixing space 20a. For example, the other end of the second conduit 42 is connected to the joint pipe 133. In this embodiment, the space within the first conduit 41, the space within the second conduit 42, and at least a portion of the space in the detergent box 30 collectively constitute at least a portion of the first waterway 40A.

[0206] For some examples, see Figures 3 to 12The laundry treatment apparatus includes a third conduit 50. One end of the third conduit 50 is connected to a water source and is connected to the mixing space 20a, thereby directing water from the water source into the mixing space 20a. For example, the third conduit 50 is connected to the insertion tube 131. In this embodiment, the space within the third conduit 50 defines a portion of the second water channel 50A.

[0207] It should be noted that the first pipeline 41 can be a complete pipe or can be formed by connecting multiple pipe sections, which is not limited here.

[0208] The second pipeline 42 can be a complete pipe or can be formed by connecting multiple pipe sections, which is not limited here.

[0209] The third pipeline 50 can be a complete pipe or can be formed by connecting multiple pipe sections, which is not limited here.

[0210] In some embodiments, the door seal 60 has an installation opening, and the water outlet of the mixing space 20a passes through the installation opening of the door seal 60 and extends radially inward of the door seal 60. For example, the nozzle 130 is installed through the door seal 60, and the side wall of the nozzle 130 with the liquid outlet 20ab can extend radially inward of the door seal 60. This facilitates the direct delivery of the detergent mixed solution from the water outlet of the mixing space 20a into the laundry treatment chamber.

[0211] In some embodiments, the liquid outlet 20ab extends radially inwardly of the door seal 60 and is inclined to discharge water toward the lower rear of the clothing treatment chamber, so that the sprayed mixed liquid covers a large area of ​​the clothing in the clothing treatment chamber.

[0212] In some embodiments, the outer barrel 11 has a water inlet, and the second drain port 30a is connected to the water inlet, which is used to guide the overflowing detergent mixed solution in the detergent box 30 to the outer barrel 11, and then enter the inner barrel through the flow hole of the inner barrel, which can assist the water inlet.

[0213] For example, Figure 1 As shown, the clothes treating apparatus further includes a water outlet pipe 70 , which connects the second drain port 30 a and the water inlet.

[0214] For some examples, see Figure 3 The water inlet valve 90 has a first outlet 90a, and the first water channel 40A and the second water channel 50A are both connected to the first outlet 90a. Water is supplied to the laundry processing device through the water inlet valve 90. The first water channel 40A and the second water channel 50A are both connected to the first outlet 90a of the water inlet valve 90. This facilitates the installation of the first water channel 40A and the second water channel 50A, simplifies the configuration of the water inlet valve 90, and saves costs.

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

[0216] At least part of the detergent box 30 is formed on the workbench 80, which means that part of the physical structure of the workbench 80 constitutes at least part of the physical structure of the detergent box 30. For example, at least part of the detergent box 30 can be integrally formed with the workbench 80.

[0217] In this embodiment, at least a portion of the detergent box 30 is formed on the workbench 80, and part of the structure of the workbench 80 is reused as at least a portion of the detergent box 30, which can reduce the number of parts, simplify the structure, and save costs.

[0218] In one embodiment, the detergent box 30 and the workbench 80 may be separate structures. That is, the detergent box 30 and the workbench 80 are manufactured separately and then assembled together through a detachable connection or a non-detachable connection.

[0219] For example, the cannula 131 and the workbench 80 can be separate structures. In other words, the cannula 131 and the workbench 80 can be manufactured separately and then assembled.

[0220] For example, the housing 132 of the spray head 130 may be formed on the workbench 80 . In other words, the housing 132 may be integrally formed with the workbench 80 .

[0221] In another embodiment, a portion of the housing 132 is formed on the workbench 80 , and another portion of the housing 132 can be a separate structure. For example, the partition member 150 constitutes another portion of the housing 132 .

[0222] For some examples, see Figures 14 to 26 For a pulsator-type laundry treatment device with a workbench 80, the detergent box 30 and the spray head 130 can be part of the workbench 80. For example, the portion of the workbench 80 used to house the dispenser box 140 is the detergent box 30. Part of the workbench 80 is also part of the detergent box 30 and the spray head 130. This reuse of the workbench 80 as part of the detergent box 30 and the spray head 130 can reduce the number of parts, material usage, and material costs.

[0223] In one embodiment, please refer to Figures 13 to 26A pumping port 80b is formed on the surface of the workbench 80 facing the clothing delivery port 80a. The pumping port 80b is connected to the cavity of the detergent box 30, and the dispenser box 140 enters and exits the detergent box 30 through the pumping 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 pumping port 80b. When detergent addition is complete, the dispenser box 140 can be pushed back into the detergent box 30 through the pumping port 80b. During the washing process, the detergent and other fluids in the detergent delivery chamber 140a can flow through the first water channel 40A, for example, in sequence through the accommodating chamber 30e, the mixing chamber 30d, the liquid outlet channel 130b, and the mixing space 20a, and finally be delivered to the clothing processing chamber from the liquid outlet 20ab. The detergent and other fluids in the accommodating chamber 30e can also overflow into the overflow chamber 30c and enter the clothing processing chamber through the pumping port 80b.

[0224] For some examples, see Figures 17 to 26 , a portion of the pumping port 80b of the workbench 80 can constitute the second drain port 30a.
