Referring to fig. 10 to 12, the detergent dispensing device includes a first waterway 40A and a fluid channel 130A, a sidewall of the first waterway 40A is opened to form a liquid outlet 20ab, and the first waterway 40A includes a mixing space 20A. The flow channel 130A has a second water outlet end 50Aa, and at least one of the first waterway 40A and the flow channel 130A delivers the detergent mixed solution, and the second water outlet end 50Aa communicates with the liquid outlet 20ab through the mixing space 20A.

The second water outlet 50Aa communicates with the liquid outlet 20ab through the mixing space 20a, that is, the fluid discharged from the second water outlet 50Aa is first mixed with the fluid in the mixing space 20a and then discharged from the liquid outlet 20ab to the laundry treating chamber.

At least one of the first waterway 40A and the flow channel 130A delivers a detergent mixed solution, for example, the first waterway 40A delivers a detergent mixed solution, the flow channel 130A delivers other fluids, for example, the flow channel 130A delivers a detergent mixed solution, the first waterway 40A delivers other fluids, and for example, the first waterway 40A and the flow channel 130A both deliver a detergent mixed solution.

Other fluids include, but are not limited to, aqueous solutions or solutions with other care ingredients added, and the like. The aqueous liquid includes, but is not limited to, tap water or circulating water from a water source.

It is understood that the first waterway 40A and the flow channel 130A are both used for delivering fluid, and that the detergent mixed solution and the aqueous solution are both fluids.

The fluid within the mixing space 20a includes, but is not limited to, a detergent mixed solution of detergent and aqueous liquid. The liquid outlet 20ab is for discharging the fluid in the mixing space 20 a.

According to the detergent dispensing device provided by the embodiment of the application, the side wall of the first waterway 40A is opened to form the liquid outlet 20ab, the dispensing structure is simplified, the second water outlet end 50Aa is communicated with the liquid outlet 20ab through the mixing space 20A, and the fluid discharged by the second water outlet end 50Aa enters the mixing space 20A to be converged and mixed with the fluid of the first waterway 40A, so that the mixing effect is improved, and the detergent such as washing powder is more fully dissolved.

In one embodiment, referring to fig. 10 to 12, the first waterway 40A includes a liquid outlet channel 130b, the liquid outlet channel 130b has a first water outlet end 40Aa, and the first water outlet end 40Aa is communicated with the mixing space 20A. In other words, the outlet passage 130b is located upstream of the mixing space 20A along the fluid flow direction of the first waterway 40A. The fluid in the liquid outlet channel 130b enters the mixing space 20a through the first water outlet end 40 Aa.

In some embodiments, referring to fig. 10 to 12, the sidewall of the liquid outlet channel 130b is opened to form a first water outlet 40Aa. The liquid flow channel 130a is located on the side of the liquid flow channel 130b where the first water outlet end 40Aa is located. That is, the first water outlet 40Aa and the liquid flow channel 130a are located on the same side of the liquid flow channel 130 b.

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

It should be noted that the detergent mixed solution mentioned in the present application is only for convenience of description, and refers to a mixed solution in which a detergent is dissolved, and the mass percentage concentration of the detergent mixed solution is not limited, and the detergent mixed solution is not limited to be completely dissolved. In some embodiments, the detergent mixed solution may be a user-added detergent stock solution. In other embodiments, the detergent mixture may be a detergent mixed with water from a water source.

The function of the detergent is not limited and includes, but is not limited to, cleaning, softening and/or fragrancing, and the like.

The type of detergent is not limited and includes, but is not limited to, cleaners, softeners and/or aromatherapy agents and the like.

The form of the detergent is not limited, and may be a powdery washing powder, a flowable washing liquid, or the like.

In this embodiment, the side wall of the liquid outlet channel 130b is opened to form a first water outlet end 40Aa, and the liquid outlet channel 130a is located at one side of the liquid outlet channel 130b where the first water outlet end 40Aa is located, so that the fluid output from the first water outlet end 40Aa flows substantially towards the liquid outlet channel 130a, so that the fluid output from the first water outlet end 40Aa contacts the fluid output from the second water outlet end 50Aa as soon as possible.

It should be noted that, the first water outlet 40Aa indicates a portion of the fluid in the fluid channel 130b leaving the fluid channel 130b, the second water outlet 50Aa indicates a portion of the fluid in the fluid channel 130a leaving the fluid channel 130a, and the mixing space 20a may be a chamber formed in a solid structure.

An embodiment of the present application provides a laundry treatment apparatus comprising a detergent dispensing device and a laundry treatment chamber according to any of the embodiments of the present application, the liquid outlet 20ab delivering a fluid into the laundry treatment chamber. That is, the fluid supplied from the first waterway 40A and the fluid flow path 130A finally enters the laundry treating chamber for treating laundry.

In one embodiment, referring to fig. 12, the liquid outlet channel 130b includes an expansion section, and the maximum flow area of the expansion section is the first water outlet 40Aa. That is, the fluid in the liquid outlet channel 130b is finally ejected from the expansion section into the mixing space 20 a. The expansion section can reduce head loss, promoting rapid discharge of the fluid in the liquid outlet passage 130 b.

The flow cross section is a cross section taken perpendicular to the flow line clusters. When the flow line clusters are not parallel to each other, the flow section is a curved surface, and when the flow line clusters are parallel to each other, the flow section is a plane. The flow area refers to the area of the flow cross section.

In one embodiment, the flow area of the expansion section increases gradually from the direction away from the first water outlet end 40Aa to the direction toward the first water outlet end 40 Aa. The fluid tends to concentrate toward the mixing space 20a under the guidance of the expansion section so as to fill the mixing space 20a as much as possible, and to be sufficiently mixed with the fluid discharged from the second water outlet end 50 Aa.

In an embodiment, referring to fig. 10 to 12, the area of the first water outlet 40Aa is larger than the area of the second water outlet 50Aa, and the area of the first water outlet 40Aa is smaller than the area of the liquid outlet 20 ab. The liquid outlet 20ab is for discharging the fluid in the mixing space 20 a. The fluid conveyed by the liquid outlet channel 130b and the fluid conveyed by the liquid flow channel 130a are converged and mixed in the mixing space 20a, and the mixed fluid is discharged from the liquid outlet 20ab and enters the clothes treating cavity to participate in clothes treatment. By such a design, the reverse flow phenomenon caused when the flow difference between the first water outlet end 40Aa and the second water outlet end 50Aa is excessively large can be effectively suppressed, and the fluid in the mixing space 20a is prevented from flowing back into the liquid outlet passage 130b as much as possible.

The area of the first water outlet 40Aa refers to the flow area of the first water outlet 40 Aa. The area of the second water outlet 50Aa is referred to as the overflow area of the second water outlet 50 Aa. The area of the liquid outlet 20ab indicates the overflow area of the liquid outlet 20 ab.

In one embodiment, referring to fig. 10 to 12, the fluid channel 130a is provided with a pressurizing structure 120, and the pressurizing structure 120 is used to increase the flow rate of the fluid. For example, the pressurization structure 120 is used to increase the flow rate of the fluid in the flow channel 130 a.

In this embodiment, the pressurizing structure 120 accelerates the fluid in the fluid channel 130a, and there is a difference in flow rate between the fluid in the fluid channel 130b and the fluid in the fluid channel 130a, for example, the flow rate of the fluid in the fluid channel 130a is increased through the pressurizing structure 120, the flow rate of the second water outlet end 50Aa is greater than the flow rate of the first water outlet end 40Aa, and the flow rate of the two fluids entering the mixing space 20a is faster or slower, wherein the one with the faster flow rate can generate impact and disturbance on the one with the slower flow rate, so that the two fluids can mix better when meeting, and further promote the dissolution of the detergent.

In one embodiment, referring to fig. 10 to 12, the pressurizing structure 120 includes a reduced diameter section 22, and the reduced diameter section 22 increases the flow rate of the second water outlet 50 Aa. The reduced diameter section 22 is a section where the flow area of the fluid in the reduced diameter section 22 is reduced in the flow direction of the fluid. The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area of the fluid, thereby achieving good mixing effect. Meanwhile, the reducing section 22 enables the second water outlet end 50Aa to have a larger spraying speed, and can generate obvious negative pressure in a relatively larger surrounding area, so that the fluid at the first water outlet end 40Aa is sucked under the negative pressure effect and is mixed with the fluid discharged by the second water outlet end 50Aa, and the mixing effect is improved.

In some embodiments, the pressurization structure 120 comprises a powered pressurization mechanism. The power pressurizing mechanism refers to a mechanism that a power source provides power to increase fluid pressure to raise flow rate. The power source includes, but is not limited to, electrical energy or other energy sources. The dynamic pressurizing mechanism can actively increase the fluid flow rate, and compared with the passive increase of the fluid flow rate of the reducing section 22, the dynamic pressurizing mechanism has high automation degree.

The type of power pressurizing mechanism is not limited, and exemplary power pressurizing mechanisms include, but are not limited to, water pumps, peristaltic pumps, and the like.

In some embodiments, the end of the pressurization structure 120 forms the second water outlet end 50Aa. That is, the fluid of the second waterway 50A is directly ejected from the pressurized structure 120, such as the end of the reduced diameter section 22.

In some embodiments, referring to fig. 10 to 12, the end of the pressing 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 form a second water outlet end 50Aa.

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

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

For another example, the end of the pressurizing structure 120 is connected to the constant diameter section 23 and the expanded diameter section, and any one of the constant diameter section 23 and the expanded diameter section forms the second water outlet end 50Aa.

The constant diameter section 23 refers to a substantially constant flow area of the fluid in the constant diameter section 23 along the flow direction of the fluid.

The expansion section refers to a flow direction of the fluid, and an overflow area of the fluid in the expansion section becomes large.

In this embodiment, the fluid of the fluid flow channel 130a is ejected directly from the constant diameter section 23 and/or the expanded diameter section to the mixing space 20a. The fluid accelerated by the pressurizing structure 120 flows through the constant diameter section 23 and/or the expanding section, and can be conically and divergently discharged into the mixing space 20a at a relatively high speed.

In some embodiments, the extension of the constant diameter section 23 along the second waterway 50A is less than or equal to the extension of the reduced diameter section 22 along the second waterway 50A. Since the longer the fluid flow path, the more significant the energy loss thereof, 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.

In some embodiments, the extension of the expanded diameter section along second waterway 50A is less than or equal to the extension of reduced diameter section 22 along second waterway 50A. Since the longer the fluid flow path, the more significant the energy loss thereof, limiting the length of the expanded diameter section can reduce the loss of impact force after the fluid flows out of the reduced diameter section 22.

In one embodiment, referring to fig. 10-12, the tip of the pressing structure 120 protrudes into the mixing space 20a. The tip of the pressurizing structure 120 protrudes 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 tail end of the pressurizing structure 120, the impact force of the accelerated fluid is increased, the fluid in the mixing space 20a can be better stirred, the mixing effect of the fluid in the mixing space 20a is improved, and the cleaning ratio is improved.

In one embodiment, referring to fig. 10 to 12, the flow channel 130a is provided with a turbulence structure 21, and the turbulence structure 21 is used to provide a circumferential velocity component to the fluid. For example, the turbulence structures 21 are used to provide a circumferential velocity component to the fluid in the flow channel 130 a.

The above-mentioned provision of the circumferential velocity component means that the fluid passing through the turbulence structure 21 in the flow channel 130a has a velocity component in the circumferential direction of the flow channel 130a which is not zero, and the circumferential direction of the flow channel 130a surrounds the extending direction of the flow channel 130 a.

After passing through the turbulent flow structure 21, the fluid in the fluid channel 130a generates multi-directional compound motion along the circumferential direction, the advancing direction and the like, so that the fluid is better mixed with the fluid in the mixing space 20a, the mixing efficiency is improved, the fluid sprayed by the fluid outlet 20ab can be scattered in a conical shape, the radiation range is wider, and the visual effect is better.

It will be appreciated that the turbulence structures 21 may also increase the flow rate of the fluid by limiting the area of the flow channel 130a in which they are located. In this way, the two streams entering the mixing space 20a are made to differ more in velocity, further promoting detergent dissolution.

In one embodiment, referring to fig. 10-12, the turbulence structure 21 includes one or more helical blades for guiding the fluid in a helical motion. For example, helical blades are used to guide the helical movement of fluid in flow channel 130 a. The helical blade means a blade having a spiral line shape, the blade extending in a spiral direction. After the fluid passes through the spiral blade, the spiral motion is realized, the spiral blade has a circumferential speed component, the spiral blade has a simple structure, the turbulence effect on the fluid is good, the resistance is small, and the energy loss of the fluid during the passage is reduced.

Illustratively, the turbulating structure 21 includes one or more helical blades that divide at least a portion of the length of the flow channel 130a into a plurality of sub-channels.

The above-mentioned plural means that the number of the helical blades is plural, and may be two, three or more, that is, the number of the heads of the helical line is not less than two, and the number of turns of the helical line is not limited.

In some embodiments, referring to fig. 10 to 12, the outer edge of the spiral blade along the spiral direction is connected to the inner wall of the flow channel 130a, and the inner edge of the spiral blade along the spiral direction is spaced apart from the inner wall of the flow channel 130 a. I.e., the inner edges of the helical blades are spaced from the inner wall of the flow channel 130a, such that the inner wall of the flow channel 130a provides the helical blades with a connecting support.

In one embodiment, referring to fig. 10-12, the pressurization structure 120 is located downstream of the turbulence structure 21. The fluid sequentially passes through the turbulence structure 21, the pressurizing structure 120 such as the reduced diameter section 22, and then is ejected into the mixing space 20a with a tapered shape.

In one embodiment, the liquid outlet channel 130b is used for delivering the detergent mixed solution, and the liquid outlet channel 130a is used for delivering the water solution.

In this embodiment, the liquid outlet channel 130b delivers a detergent mixed solution, such as a laundry detergent mixed solution or a laundry powder mixed solution, especially a laundry powder mixed solution. Since the washing powder is a powder detergent, the liquid outlet channel 130b is more likely to be blocked and remained than the washing liquid, and therefore, the liquid outlet channel 130b is used for conveying the washing liquid mixed solution, the pressurizing structure 120 and/or the turbulence structure 21 are arranged in the liquid outlet channel 130a, the liquid outlet channel 130a is used for conveying water of a water source, and the pressurizing structure 120 and/or the turbulence structure 21 are prevented from contacting the washing powder to a certain extent.

In one embodiment, referring to fig. 10 to 12, the detergent dispensing device includes a nozzle 130, the nozzle 130 is formed with a liquid outlet channel 130b, a liquid flow channel 130a and a mixing space 20a, the liquid outlet 20ab penetrates through the outer surface of the sidewall of the nozzle 130, and at least part of the liquid flow channel 130a extends into the mixing space 20 a. That is, the fluid in the mixing space 20a is sprayed to the laundry treating chamber through the liquid outlet 20ab of the spray head 130, and at least part of the liquid flow channel 130a extends into the mixing space 20a, so that the fluid in the mixing space 20a can be better stirred, and the mixing effect of the fluid in the mixing space 20a can be improved.

In one embodiment, referring to fig. 10 to 12, the portion of the liquid channel 130a located in the mixing space 20a extends along the first direction, and the liquid channel 130b is located at one side of the liquid channel 130a along the second direction, where the first direction and the second direction intersect. In this way, the fluid discharged from the fluid channel 130a enters the mixing space 20a substantially along the first direction, and the fluid discharged from the fluid channel 130b enters the mixing space 20a substantially along the second direction, and the flow directions of the two fluids intersect, so that the impact effect can be improved. In the case where the flow rate of the fluid discharged from the flow channel 130a is greater than the flow rate of the fluid discharged from the flow channel 130b, a negative pressure is generated in the vicinity of the second water outlet end 50Aa, so that the fluid of the first water outlet end 40Aa is sucked under the negative pressure to change the flow direction to flow in the first direction, and foam is generated in the fluid, enhancing the mixing uniformity of the detergent such as the washing powder.

For example, the pressurizing structure 120 may be formed at a portion of the liquid flow channel 130a located in the mixing space 20 a. Turbulence structures 21 may be formed at a location of the flow channel 130a within the mixing space 20 a.

In one embodiment, referring to fig. 10 to 12, the spray head 130 includes a housing 132 and a cannula 131, the housing 132 forms a liquid outlet channel 130b, a mixing space 20a and a liquid outlet 20ab, at least part of the cannula 131 is inserted into the mixing space 20a, and the cannula 131 forms a liquid flow channel 130a. That is, the liquid outlet 20ab penetrates the outer surface of the sidewall of the housing 132, and the second water outlet 50Aa is formed at the cannula 131. Illustratively, the port of cannula 131 within mixing space 20a is second outlet end 50Aa. The spray head 130 has a simple structure and is easy to manufacture.

In some embodiments, the showerhead 130 may be an integrally formed structure. For example, the spray head 130 may be a unitary injection molded structure.

For example, referring to fig. 10 to 12, the port of the cannula 131 facing the first direction is a second water outlet 50Aa, and the first water outlet 40Aa is formed on the sidewall of the mixing space 20a along the second direction. So designed, the fluid exiting the first water outlet 40Aa flows generally in a first direction and the fluid exiting the second water outlet 50Aa flows generally in a second direction, with the two fluids meeting and mixing in the mixing space 20a.

In an embodiment, referring to fig. 10 to 12, a side wall of the housing 132 along the first direction is formed with a liquid outlet 20ab. Illustratively, the liquid outlet 20ab is formed in a sidewall of the housing 132 along the first direction. The fluid in the mixing space 20a is ejected to the outside of the head 130 through the liquid outlet 20ab.

In one embodiment, referring to fig. 2, a nozzle 130 is disposed on the door seal 60. The door seal 60 not only provides a mounting position for the spray head 130, but also enables the detergent mixed solution sprayed from the spray head 130 to be closer to the laundry treating chamber.

In some embodiments, the spray head 130 may be removably linked or non-removably connected to the door seal 60.

In one embodiment, referring to fig. 1 and 2, the space enclosed by the door seal 60 is a part of the laundry treating chamber, and the liquid outlet 20ab extends into the radial inner side of the door seal 60. Fluid exiting the outlet 20ab may be directed into the space enclosed by the door seal 60 and thus directly into the laundry treatment chamber.

The extending direction of the axis of the door seal 60 coincides with the extending direction of the axis of the cylinder assembly 10, and the axis of the door seal 60 may extend in a horizontal direction or an oblique direction.

In one embodiment, referring to fig. 10 to 12, the detergent dispensing device includes a nozzle 130, the nozzle 130 has a mixing space 20a, and a liquid outlet 20ab penetrates through an outer surface of a sidewall of the nozzle 130. The head 130 forms the mixing space 20a, that is, the fluid in the liquid outlet channel 130b and the fluid in the liquid flow channel 130a are mixed together in the head 130. The liquid outlet 20ab penetrates through the outer surface of the side wall of the spray head 130, and the fluid in the spray head 130 is sprayed out through the liquid outlet 20ab, so that the fluid of the two waterways is sprayed to the clothes treating cavity through the spray head 130.

In an embodiment, referring to fig. 10 to 12, a side wall of the nozzle 130 along a first direction forms a liquid outlet 20ab, a first water outlet 40Aa is formed on a side wall of the mixing space 20a along a second direction, and the first direction and the second direction intersect.

In this embodiment, the liquid outlet 20ab is formed on a side wall of the nozzle 130 along the first direction, the first water outlet 40Aa is formed on a side wall of the mixing space 20a along the second direction, that is, the fluid discharged from the first water outlet 40Aa enters the mixing space 20a along the second direction, and is mixed with the fluid from the second water outlet 50Aa, and then is ejected along the first direction through the liquid outlet 20ab, so that the flow path of the fluid discharged from the first water outlet 40Aa can be increased appropriately, and the mixing effect can be improved.

In one embodiment, the liquid outlet 20ab is in direct communication with the laundry treating chamber. The direct communication of the liquid outlet 20ab with the laundry treating chamber is an indication that the liquid outlet 20ab is open to the laundry treating chamber, and that the fluid from the liquid outlet 20ab directly enters the laundry treating chamber. There is no transit passage, such as a transit tube or other fluid-permeable member, between the outlet 20ab and the laundry treating chamber. The fluid from the outlet 20ab is not guided by the transit passage, but is directly put into the clothes treating chamber under the action of the gravity and the flow rate of the fluid.

In this embodiment, the liquid outlet 20ab is directly communicated with the clothes treating cavity, the fluid from the liquid outlet 20ab directly enters the clothes treating cavity, a transit passage is not required to be arranged between the liquid outlet 20ab and the clothes treating cavity, the transit passage is saved, the production cost is reduced, and the fluid such as detergent mixed solution can directly enter the clothes treating cavity from the liquid outlet 20ab and directly act on clothes.

It will be appreciated that the liquid outlet 20ab may extend through the outer surface of the physical structure in which it is located.

In one embodiment, the liquid outlet 20ab may also be connected to the transit passage. That is, the outer surface of the solid structure where the liquid outlet 20ab is located is connected to the transit passage, and the fluid from the liquid outlet 20ab flows through the transit passage and then enters the laundry treating chamber. The flow direction of the fluid and/or the shape of the fluid may be changed by the transfer passage, and the fluid may be sprayed to the laundry at a specific location and/or in a specific shape.

In one embodiment, referring to fig. 2, the liquid outlet 20ab is located in the laundry treating chamber. Illustratively, the outlet 20ab extends radially inward of the door seal 60. Thus, the distance between the liquid outlet 20ab and the clothes in the clothes treatment cavity is closer, and the probability of defoaming in the fluid sprayed out of the liquid outlet 20ab is reduced.

In an embodiment, referring to fig. 10 to 12, the second water outlet 50Aa faces the liquid outlet 20ab. The second water outlet 50Aa facing the liquid outlet 20ab means that the second water outlet 50Aa faces the same direction as the liquid outlet 20ab, for example, the second water outlet 50Aa and the liquid outlet 20ab face the same side in the first direction.

In this embodiment, the second water outlet 50Aa faces the liquid outlet 20ab, and the liquid outlet 20ab is downstream in 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 liquid outlet 20ab, and the fluid from the second water outlet 50Aa can flow to the liquid outlet 20ab and be discharged quickly without changing the flow direction as much as possible.

In an embodiment, referring to fig. 10 to 12, a plane of the liquid outlet 20ab is taken as a projection plane, and a projection of the second water outlet 50Aa on the projection plane is located in a projection range of the liquid outlet 20ab on the projection plane. For example, the flow area of the liquid outlet 20ab may be larger than the flow area of the second water outlet 50 Aa. In this way, the fluid flow direction change caused by the dislocation of the second water outlet end 50Aa and the liquid outlet 20ab can be avoided.

In one embodiment, referring to fig. 10 to 12, the distance between the turbulence structure 21 and the pressurizing structure 120 is greater than the distance between the liquid outlet 20ab and the pressurizing structure 120. By the design, the path of the fluid between the turbulent flow structure 21 and the pressurizing structure 120 is larger than the path of the fluid between the pressurizing structure 120 and the liquid outlet 20ab, the fluid can be effectively accelerated by the turbulent flow structure 21 and the pressurizing structure 120, and can be timely discharged out of the mixing space 20a, so that loss in the flowing process is reduced.

In one embodiment, the axis of the first outlet end 40Aa intersects the projection of the axis of the second outlet end 50Aa in a horizontal plane. That is, the horizontal plane is taken as a projection plane, and the projection of the axis of the first water outlet end 40Aa and the projection of the axis of the second water outlet end 50Aa intersect.

The axis of the first water outlet 40Aa is a straight line passing through the center point of the flow cross section of the first water outlet 40 Aa. The axis of the second water outlet end 50Aa is a straight line passing through the center point of the flow cross section of the second water outlet end 50 Aa.

In this embodiment, the fluid flowing through the liquid outlet channel 130b is ejected substantially along the axis of the first water outlet end 40Aa, the fluid flowing through the liquid outlet channel 130a is ejected substantially along the axis of the second water outlet end 50Aa, and 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, so that the fluid ejected from the first water outlet end 40Aa and the fluid ejected from the second water outlet end 50Aa can intersect, and when the two fluids intersect, the two fluids are mixed and impacted, so that the dissolution of the detergent can be further promoted, the detergent with bubbles can be advantageously put into the laundry, and the cleaning effect can be improved.

In some embodiments, referring to fig. 3 to 12, the detergent dispensing device includes a first water channel 40A and a second water channel 50A, and the liquid outlet channel 130b is a part of the first water channel 40A. The flow channel 130A is a part of the second water channel 50A, and the second water outlet end 50Aa is the water outlet end of the second water channel 50A.

The first water outlet 40Aa is a portion of the fluid in the liquid outlet channel 130b that exits the liquid outlet channel 130 b. The second water outlet 50Aa is a portion where the fluid in the second water path 50A exits the second water path 50A.

It should be noted that, in the embodiment of the present application, the first waterway 40A refers to a fluid flow path, and is not particularly limited to a pipeline structure. The second waterway 50A refers to a flow path of fluid, and is not particularly limited to a pipe type structure.

In some embodiments, the water inlet end of the first waterway 40A may be in communication with a water source, and the water inlet end of the second waterway 50A may be in communication with a water source.

It should be noted that the water source in the embodiment of the present application is a water source for supplying water to the first waterway 40A and/or the second waterway 50A, such as tap water, and may be an internal water source of the laundry treating apparatus, such as circulating water.

In one embodiment, referring to fig. 3-9, a laundry treating apparatus includes a water inlet valve 90, the water inlet valve 90 being connected to a water source, such as a tap water pipe. The first waterway 40A and the second waterway 50A may be connected to different water inlet valves 90, or may be connected to the same water inlet valve 90, which is not limited herein. As an alternative embodiment, the laundry treating apparatus includes a circulation pump, and one of the first waterway 40A and the second waterway 50A is connected to the water inlet valve 90, and the other is connected to the circulation pump of the laundry treating apparatus.

In some embodiments, the inlet valve 90 has at least two water delivery ports, with each of the first waterway 40A and the second waterway 50A communicating with one of the water delivery ports. The water source supplies water to the laundry treating apparatus through the water inlet valve 90, and the first waterway 40A and the second waterway 50A are respectively communicated with one water supply port, and water flow rates of different water supply ports may be different, so that a difference in flow rates of the fluids in the first waterway 40A and the second waterway 50A may be increased.

In some embodiments, referring to fig. 3-9, the inlet valve 90 has a first outlet 90A, and both the first waterway 40A and the second waterway 50A are in communication with the first outlet 90A. The water source supplies water to the clothes treating apparatus through the water inlet valve 90, and the first water path 40A and the second water path 50A are connected to the first outlet 90A of the water inlet valve 90, so that the installation of the first water path 40A and the second water path 50A can be facilitated, the setting of the water inlet valve 90 is simplified, and the cost is saved.

In some embodiments, referring to fig. 3 to 12, the detergent dispensing device includes a detergent supply assembly including a detergent passage and a first water outlet 30b, the detergent passage being in communication with an atmosphere, a first waterway 40A being in communication with a water source, the detergent passage, the first water outlet 30b and the liquid outlet 20ab, and a second waterway 50A being in communication with the water source and the mixing space 20A.

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

The first waterway 40A communicates with a water source, a detergent passage, the first drain port 30b, and the liquid outlet 20ab. That is, the detergent passage, the first drain port 30b, and the mixing space 20A constitute at least a part of the first waterway 40A. Fluid from the water source flows through the detergent passage and the first drain outlet 30b, for example, the fluid from the water source in the first waterway 40A flows through the portion containing the detergent and is mixed with the detergent to form a detergent mixed solution, and the detergent mixed solution flows to the first drain outlet 30b to be discharged through the first drain outlet 30b and flows to the mixing space 20A.

The second waterway 50A does not flow through the first drain port 30b, and the detergent mixture solution delivered from the first waterway 40A can be intersected with the fluid of the second waterway 50A in the mixing space 20A.

In this embodiment, the detergent passage communicates with the atmosphere to form a pressure relief space. When the water pressure of any section of the fluid in the first waterway 40A at the water inlet end of the first waterway 40A connected to the water source is the initial water pressure, the fluid pressure of the first waterway 40A is reduced, namely, the pressure is relieved, due to the fact that the fluid enters the pressure relief space from the closed pipe section when the fluid in the first waterway 40A flows through the detergent passageway, the fluid after pressure relief flows from the first water outlet 30b to the water inlet end of the mixing space 20A, and the water pressure of any section of the fluid flowing through the first waterway 40A at the water inlet end of the mixing space 20A is smaller than the initial water pressure of any section of the fluid at the water inlet end of the first waterway 40A connected to the water source. That is, the fluid of the water source enters the first waterway 40A at a relatively large pressure, and pressure relief is experienced in the detergent passage, so that the water pressure at the end of the first waterway 40A is smaller than that at the water inlet end thereof.

In some embodiments, referring to fig. 3 to 12, the detergent passage includes a mixing chamber 30d, a wall surface of the mixing chamber 30d forms a first drain port 30b, the detergent supply assembly includes a second drain port 30a and an overflow chamber 30c, the overflow chamber 30c is used to receive the detergent mixed solution overflowed from the detergent passage, and the second drain port 30a is used to drain the detergent mixed solution in the overflow chamber 30 c. The first drain port 30b is used to drain the detergent mixed solution in the mixing chamber 30 d.

In this embodiment, when the liquid level in the detergent passage, e.g., the mixing chamber 30d, is not higher than the overflow liquid level, the fluid in the mixing chamber 30d is discharged from the first drain port 30b and flows into the mixing space 20a. When the liquid level in the mixing chamber 30d is higher than the overflow liquid level, the excessive fluid overflows into the overflow chamber 30c and is discharged from the second drain outlet 30a, that is, the detergent mixed solution is discharged from the first drain outlet 30b preferentially, the second drain outlet 30a plays a role in safety protection, and the excessive fluid in the mixing chamber 30d can be discharged timely.

Illustratively, the flow area of the second drain opening 30a is larger than the flow area of the first drain opening 30b, that is, the second drain opening 30a has a larger drain volume than the first drain opening 30b in the case where the amount of water is equally sufficient. Since the flow area of the first drain opening 30b is small, the flow rate of the water discharged from the first drain opening 30b is relatively small. The second water outlet 30A and the overflow cavity 30c can timely discharge the detergent mixed solution or water flow of the first waterway 40A under the overflow condition, so that the water flow is lightened, and the safety protection function is realized.

In some embodiments, the detergent passage includes a detergent delivery chamber 140A, and the detergent delivery chamber 140A may be adapted to contain powdered detergent, and initially dissolve the detergent when fluid from the first waterway 40A flows through the detergent delivery chamber 140A. Of course, the detergent delivery chamber 140a may also be adapted to contain a detergent having a flow characteristic.

In some embodiments, referring to fig. 3 to 12, the detergent supply assembly includes a detergent box 30 and a dispenser box 140 disposed in the detergent box 30, the dispenser box 140 having a detergent dispensing chamber 140a, the detergent box 30 having a mixing chamber 30d and an overflow chamber 30c, the mixing chamber 30d being located below the dispenser box 140, the mixing chamber 30d being for receiving a detergent mixed solution flowing through the detergent dispensing chamber 140a, a first water outlet 30b being disposed at a wall of the mixing chamber 30d, and the overflow chamber 30c being for receiving a detergent mixed solution overflowed from the mixing chamber 30 d.

The detergent in the detergent delivery chamber 140a can flow to the first drain port 30b by the water. Illustratively, the upper sidewall of the dispenser box 140 forms an addition port that communicates with the detergent delivery chamber 140 a. In a state that a portion of the detergent putting chamber 140a is located outside the detergent box 30, a user may inject detergent into the detergent putting chamber 140a through the addition port, and in a state that the detergent putting chamber 140a is located inside the detergent box 30, water flow may wash the detergent putting chamber 140a through the addition port to send the detergent mixed solution into the mixing chamber 30 d.

The mixing chamber 30d is used for receiving the fluid flowing through the detergent dispensing chamber 140a, and the first water outlet 30b is disposed on a wall of the mixing chamber 30 d. I.e., the detergent mixed solution, enters the mixing chamber 30d and is discharged from the first water discharge port 30 b.

The first drain opening 30b may be formed by the detergent box 30 itself, or may be formed by a water outlet end of a waterway structure additionally provided at the top, side, or bottom of the detergent box 30.

In some embodiments, the dispenser box 140 is drawably disposed within the detergent box 30, for example, the dispenser box 140 is at least partially withdrawn from the detergent box 30 to the outside of the detergent box 30, and a user can put detergent into the detergent putting cavity 140 a.

Illustratively, in a state in which the dispenser box 140 is received in the detergent box 30, the mixing chamber 30d is located under the dispenser box 140, and the detergent mixed solution flows from the detergent delivery chamber 140a of the dispenser box 140 to the mixing chamber 30d under the dispenser box 140 and is discharged from the first drain outlet 30 b.

In one embodiment, referring to fig. 3 to 12, the detergent supply assembly includes a water blocking rib 170, the detergent box 30 has a cavity, the water blocking rib 170 extends upward along a wall of the cavity to divide the cavity into a subchamber and an overflow chamber 30c, at least part of the subchamber is a mixing chamber 30d, a sidewall of the mixing chamber 30d forms a first drain opening 30b, and a sidewall of the overflow chamber 30c forms a second drain opening 30a.

It will be appreciated that the top end of the water deflector 170 may be spaced from the upper surface of the cavity, and the level of the fluid in the mixing chamber 30d may be higher than the height of the water deflector 170, and the fluid in the mixing chamber 30d may overflow to the overflow chamber 30c through the gap between the water deflector 170 and the upper surface of the cavity.

In this embodiment, the water blocking rib 170 separates the subchamber from the overflow chamber 30c, and the fluid level in the mixing chamber 30d is higher than the height of the water blocking rib 170, and the fluid in the mixing chamber 30d can overflow to the overflow chamber 30c through the gap between the water blocking rib 170 and the upper surface of the cavity.

In one embodiment, referring to fig. 3 to 12, the detergent supply assembly includes a filter plate 160 having a filter hole 160a, the filter plate 160 dividing the subchamber into a receiving chamber 30e and a mixing chamber 30d, the filter hole 160a communicating with the receiving chamber 30e and the mixing chamber 30d, and the discharge port 140b communicating with the receiving chamber 30 e. Illustratively, the exhaust port 140b may be located within the receiving chamber 30 e. The accommodating chamber 30e and the mixing chamber 30d share the filter plate 160.

In this embodiment, the fluid discharged from the discharge port 140b flows through the receiving chamber 30e, the filtering holes 160a and the mixing chamber 30d in this order, that is, the fluid discharged from the discharge port 140b first passes through the receiving chamber 30e, is filtered by the filter plate 160, and then enters the mixing chamber 30d through the filtering holes 160 a. Taking washing powder as an example, the washing powder in the detergent delivery chamber 140a is impacted and dissolved by the water flow, and the problem of insufficient dissolution of the washing powder is easy to occur because the time period for impacting the washing powder in the detergent delivery chamber 140a is short, the filter plate 160 can temporarily hold particles larger than or equal to the aperture of the filter hole 160a in the accommodating chamber 30e, and particles smaller than the aperture of the filter hole 160a can enter the mixing chamber 30d and then enter the laundry treating chamber through the first discharge port 140 b. During the washing process, the detergent mixed solution from the washing input chamber can repeatedly wash the washing powder retained in the receiving chamber 30e so that the washing powder is re-dissolved and then enters the mixing chamber 30d. By the design, the dissolving effect of the washing powder is better, particles of the washing powder entering the clothes treatment cavity are relatively smaller, and the cleaning effect is improved.

It is understood that the detergent dispensing chamber 140A, the receiving chamber 30e, the mixing chamber 30d, the liquid outlet channel 130b and the mixing space 20A are all part of the first waterway 40A.

The second waterway 50A may include a fluid path between the inlet valve 90 to the second outlet end 50 Aa.

In one embodiment, referring to fig. 3-9, the receiving chamber 30e is located above the mixing chamber 30d. That is, the thickness direction of the filter plate 160 may coincide with the up-down direction. The filter plate 160 may retain particles larger than or equal to the aperture of the filter hole 160a on the upper surface of the filter plate 160, and particles smaller than the aperture of the filter hole 160a may enter the mixing chamber 30d below and then enter the laundry treating chamber through the first discharge port 140 b. During the washing process, the detergent mixture solution from the washing input chamber can repeatedly wash the washing powder on the upper surface of the filter plate 160 so that the washing powder is re-dissolved and then enters the mixing chamber 30d. The dissolving effect of the washing powder is better, the particles of the washing powder entering the clothes treatment cavity are relatively smaller, and the cleaning effect is improved.
