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.

Compared with the mode that washing powder and liquid detergent respectively enter the first water outlet tank and the second water outlet tank in the related art, in the detergent supply assembly provided by the embodiment of the application, at least two discharge ports 140b are communicated with the mixing cavity 30d, so that the detergents in the plurality of detergent delivery cavities 140a can enter the mixing cavity 30d and be discharged to the clothes treatment cavity through the mixing cavity 30d, and the waterway is simple. In the process of putting in the detergent, the user does not need to specially distinguish liquid laundry detergent and powdery laundry powder, and the laundry detergent and the laundry powder can be put in any one of the plurality of detergent putting cavities 140a, so that the putting difficulty of the user is reduced, the use efficiency of different types of detergents is improved, and the user experience is improved.

In some embodiments, referring to fig. 21, an upper surface of the dispenser box 140 forms an addition port communicating with the detergent delivery chamber 140 a. The user can add detergent to the detergent dispensing chamber 140a through the addition port from above.

In some embodiments, the detergent in the detergent delivery chamber 140a may be caused to enter the mixing chamber 30d by flushing the detergent delivery chamber 140a with a water flow. Illustratively, the water jets may spray water into the detergent delivery chamber 140a, where the water stream impinges on the detergent in the wash delivery chamber to create a detergent mixture solution that enters the mixing chamber 30d through the discharge outlet 140 b.

In some embodiments, the water jets may be formed in the detergent box 30 or the table 80, etc.

In one embodiment, the water jet may be located above the detergent delivery chamber 140 a. For example, the detergent box 30 includes a box cover and a box body, the box cover being disposed above the box body and collectively defining a cavity, a portion of which may be the mixing chamber 30d, the box cover forming a water jet.

In one embodiment, referring to fig. 9, 13, 21 and 26, the dispenser box 140 is provided to the detergent box 30 to be accessible. Illustratively, the dispenser box 140 is drawably disposed within the detergent box 30, e.g., at least a portion of the dispenser box 140 is withdrawn outside the detergent box 30, a user may dispense detergent into the detergent dispensing chamber 140a, and the dispenser box 140 may be accessed, e.g., pushed into the detergent box 30, in the event that dispensing is completed or laundry is desired.

In one embodiment, referring to fig. 6 to 9 and fig. 16 to 26, the detergent box 30 includes an overflow chamber 30c, the overflow chamber 30c is used for receiving the fluid overflowed from the mixing chamber 30d, the mixing chamber 30d and the overflow chamber 30c are distributed along the upstream and downstream directions of the fluid path, the sidewall of the mixing chamber 30d forms a first drain outlet 30b, and the sidewall of the overflow chamber 30c forms a second drain outlet 30a. That is, on the same water line, the mixing chamber 30d is located upstream of the overflow chamber 30 c. Illustratively, the mixing chamber 30d and the overflow chamber 30c are distributed in the front-rear direction, for example, the mixing chamber 30d may be located at the rear side or the front side of the overflow chamber 30 c. The first drain port 30b communicates with the mixing chamber 30d to drain the fluid in the mixing chamber 30d to the laundry treating chamber. The second drain port 30a communicates with the overflow chamber 30c to drain the fluid in the overflow chamber 30c to the laundry treating chamber.

In this embodiment, in the case where the liquid level in 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 30 b. In the case that the liquid level in the mixing chamber 30d is higher than the overflow liquid level, the excessive fluid in the mixing chamber 30d overflows into the overflow chamber 30c and is discharged from the second drain port 30a, that is, the detergent mixed solution is preferentially discharged from the first drain port 30b, and the second drain port 30a plays a role in safety protection, so that the excessive fluid in the mixing chamber 30d can be timely discharged. The mixing chamber 30d and the overflow chamber 30c are distributed along the front-rear direction, the sizes of the mixing chamber 30d and the overflow chamber 30c along the left-right direction can be larger, the mixing chamber 30d is convenient to be matched with the plurality of detergent delivery chambers 140a to contain the fluid from the detergent delivery chambers 140a, and the volume of the overflow chamber 30c is moderate so as to be convenient for receiving the fluid overflowed from the mixing chamber 30 d.

For example, in one embodiment, referring to fig. 6 to 9, and 16 to 26, the mixing chamber 30d may be located at the rear side of the overflow chamber 30c, and the discharge port 140b may be formed at the rear sidewall of the dispenser box 140. For example, the projection of the discharge port 140b is located within the projection range of the mixing chamber 30d with a plane perpendicular to the up-down direction as a projection plane. The fluid discharged from the discharge port 140b is relatively far from the overflow chamber 30c, so that the problem that the fluid in the mixing chamber 30d overflows to the overflow chamber 30c without reaching the overflow level under the condition that the flow rate of the discharge port 140b is large is avoided to some extent.

It is understood that the shape and size of the discharge port 140b are not limited, and the shape and size of the discharge port 140b may be set according to the need.

The arrangement of the plurality of detergent delivery cavities 140a is not limited, and in one embodiment, referring to fig. 13, the plurality of detergent delivery cavities 140a may be arranged in the left-right direction.

In one embodiment, referring to fig. 6-9, the first drain opening 30b is located upstream of the second drain opening 30a. That is, the fluid flows through the first drain opening 30b and then through the second drain opening 30a.

In one embodiment, referring to fig. 6 to 9, the overflow area of the second drain opening 30a is larger than that of the first drain opening 30b, that is, the drainage volume of the second drain opening 30a is larger than that of the first drain opening 30b in the case where the water volume is equal and 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.

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, referring to fig. 6 to 9, the first drain opening 30b extends forward. For the drum type laundry treating apparatus, the space above the tub assembly 10 is limited, the distance between the detergent supply assembly and the tub assembly 10 is limited, and the first drain opening 30b extends forward to avoid interference with the tub assembly 10, thereby adapting the limited space above the tub assembly 10.

In one embodiment, referring to fig. 6 to 9 and 16 to 26, the detergent box 30 includes a receiving chamber 30e above a mixing chamber 30d, a filter hole 160a is formed at an upper sidewall of the mixing chamber 30d, a discharge port 140b communicates with the receiving chamber 30e, and the filter hole 160a communicates with the receiving chamber 30e and the mixing chamber 30d. Specifically, in a state where at least part of the dispenser box 140 is located inside the detergent box 30, a portion of the dispenser box 140 having the discharge port 140b is located in the accommodation chamber 30 e.

In this embodiment, the fluid in the detergent delivery chamber 140a enters the receiving chamber 30e first and then enters the mixing chamber 30d through the filter aperture 160 a. Taking detergent as washing powder as an example, the washing powder in the detergent delivery cavity 140a is impacted and dissolved by water flow, and the problem of insufficient dissolution of the washing powder is easy to occur because the time of impacting the washing powder in the detergent delivery cavity 140a by water flow is short, the upper side wall of the mixing cavity 30d can temporarily reserve particles with the aperture larger than or equal to the aperture of the filtering hole 160a on the upper side wall of the mixing cavity 30d, and the particles with the aperture smaller than the filtering hole 160a can enter the mixing cavity 30d and then enter the clothes treatment cavity through the first outlet 140 b. During the washing process, the fluid from the washing delivery chamber can repeatedly wash the washing powder on the upper sidewall of the mixing chamber 30d, 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 pore size of the filter pores 160a and the shape of the filter pores 160a may be set as desired. The shape of the filter holes 160a includes, but is not limited to, circular, oval, polygonal, or profiled, etc. The irregular shape refers to an irregular shape.

In one embodiment, the detergent supply assembly includes a filter plate 160 having filter holes 160a, the discharge port 140b is positioned above the mixing chamber 30d, and the filter plate 160 is disposed between the discharge port 140b and the mixing chamber 30 d. The filter plate 160 may be coupled to the detergent box 30. The filter plate 160 may be the upper sidewall of the mixing chamber 30d or the filter plate 160 may not be the upper sidewall of the mixing chamber 30 d.

In this embodiment, the fluid in the detergent delivery chamber 140a enters the mixing chamber 30d through the filter aperture 160 a. Taking detergent as washing powder as an example, the water flow impacts and dissolves the washing powder in the detergent delivery chamber 140a, the filter plate 160 may retain particles larger than or equal to the aperture of the filter hole 160a in the filter plate 160, and particles smaller than the aperture of the filter hole 160a may 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 mixture solution from the washing input chamber can repeatedly wash the washing powder retained in the filter plate 160 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.

In one embodiment, referring to fig. 6 to 9, 22 and 26, a plane perpendicular to the up-down direction is taken as a projection plane, and the projection of the discharge port 140b is not overlapped with the projection of the filter hole 160 a. The dispenser box 140 is provided to be movable in and out of the detergent box 30, and in a state where at least a part of the dispenser box 140 is positioned in the detergent box 30, a plane perpendicular to the up-down direction is set as a projection plane, and a projection of the discharge port 140b and a projection of the filter hole 160a do not overlap. That is, the projection of the discharge port 140b and the projection of the filter hole 160a are spaced apart, so that the fluid from the discharge port 140b contacts the solid portion of the upper sidewall of the mixing chamber 30d without the filter hole 160a and then flows to the filter hole 160a, thereby preventing the detergent mixed solution from the discharge port 140b from directly striking the filter hole 160a to some extent, and causing some particles having a particle size larger than the aperture of the filter hole 160a to be punched into the mixing chamber 30d.

In one embodiment, referring to fig. 6-9 and 16-26, the discharge port 140b is located above the mixing chamber 30 d. The fluid discharged from the discharge port 140b flows downward into the mixing chamber 30d by the flow rate and gravity. For example, the fluid discharged from the drain outlet contacts the upper sidewall of the mixing chamber 30d, filtered through the filtering holes 160a, and enters the mixing chamber 30d, and the washing powder with larger particles stays on the upper sidewall of the mixing chamber 30d, and repeatedly washes the fluid from the drain outlet 140b, and then enters the mixing chamber 30d, thereby improving the mixing uniformity.

In one embodiment, referring to fig. 6 to 9 and 22 to 26, the detergent supply assembly includes a water blocking rib 170, the detergent box 30 has a cavity, the water blocking rib 170 extends upward from a wall surface 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 side wall of the mixing chamber 30d forms a first drain outlet 30b, and a side wall of the overflow chamber 30c forms a second drain outlet 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. 6 to 9, and 22 to 26, 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.

In one embodiment, referring to fig. 6-9 and 22-26, 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.

In an embodiment, referring to fig. 6 to 9, a plane perpendicular to the up-down direction is taken as a projection plane, and the projection of the filter plate 160 and the projection of the second drain opening 30a are at least partially non-overlapping. For example, a plane perpendicular to the up-down direction is a projection plane, and the projection of the filter plate 160 and the projection portion of the second drain port 30a do not overlap. For example, the projection of the filter plate 160 and the projection of the second drain port 30a do not overlap each other with a plane perpendicular to the vertical direction as a projection plane. By such a design, the probability that the filter plate 160 shields the second drain opening 30a can be reduced to a certain extent, and the washing powder particles retained on the filter plate 160 can enter the second drain opening 30a and be discharged.

In an embodiment, referring to fig. 6 to 9, the projection of the filter plate 160 is located on one side of the projection of the water bar 170 away from the projection of the second drain opening 30a, with a plane perpendicular to the vertical direction as a projection plane. So designed, the filter plate 160 does not block the second drain opening 30a.

In one embodiment, referring to fig. 6 to 9 and fig. 22 to 26, the filter plate 160 is connected to the water bar 170. In this manner, the water deflector 170 may provide support for the filter plate 160 and may also prevent fluid communication through the gap between the filter plate 160 and the water deflector 170.

In some embodiments, the upper surface of the water deflector 170 is higher than the upper surface of the filter plate 160. That is, the water blocking rib 170 protrudes from the filter plate 160 in the up-down direction.

In some embodiments, the upper surface of the water deflector 170 is lower than the upper surface of the filter plate 160. That is, the filter plate 160 protrudes from the water bar 170 in the up-down direction.

In some embodiments, the upper surface of the water deflector 170 is flush with the upper surface of the filter plate 160.

For example, referring to fig. 6 to 9, the filter plate 160 is coupled to an upper surface of the water bar 170. The upper surface of the filter plate 160 protrudes beyond the upper surface of the water blocking rib 170, and the water blocking rib 170 does not block the laundry powder on the upper surface of the filter plate 160 from entering the overflow chamber 30c.

In some embodiments, the outer perimeter of the filter plate 160 may be coupled to the surface of the subchamber and the water deflector 170. So designed, the surfaces of the filter plate 160, the water blocking ribs 170 and the subchambers are jointly enclosed to form the mixing chamber 30d. The fluid in the receiving chamber 30e enters the mixing chamber 30d through the filter holes 160a without entering the mixing chamber 30d through the gap between the outer periphery of the filter plate 160 and the surface of the subchamber and the gap between the outer periphery of the filter plate 160 and the water blocking rib 170.

In some embodiments, the filter plate 160 may be substantially planar. The filter plate 160 is simple in structure and easy to manufacture.

In one embodiment, referring to fig. 6 to 9, the filter plate 160 is inclined downward from a direction away from the second drain opening 30a to a direction toward the second drain opening 30 a. The upper surface of the filter plate 160 is inclined downward from a direction away from the second drain port 30a to a direction toward the second drain port 30 a. So designed, fluid can flow downward along the upper surface of the filter plate 160 from a direction away from the second drain opening 30a to a direction toward the second drain opening 30a, reducing the risk of detergent accumulation on the upper surface of the filter plate 160.

In one embodiment, referring to fig. 3 to 26, the laundry treating apparatus includes a first waterway 40A and a second waterway 50A, and the detergent delivery chamber 140A and the mixing chamber 30d are both part of the first waterway 40A, and the detergent delivery chamber 140A is located upstream of the mixing chamber 30 d. The water flow impacts the washing powder in the washing and putting cavity to primarily dissolve the washing powder to form a detergent mixed solution, and the detergent mixed solution enters the mixing cavity 30d again.

The first waterway 40A has a first water outlet 40Aa, and the second waterway 50A has a second water outlet 50Aa. The first water outlet 40Aa is a portion where the fluid in the first water path 40A leaves the first water path 40A. The second water outlet 50Aa is a portion of the second water path 50A from which the fluid in the second water path 50A exits.

The first waterway 40A is used for delivering the detergent mixture solution, and the second waterway 50A is used for delivering the aqueous solution. The first waterway 40A delivers a detergent mixture solution, such as a laundry detergent mixture solution or a laundry powder mixture solution, particularly a laundry powder mixture solution. Since the washing powder is a powder detergent, it is easier to block and remain than the washing liquid, and therefore, the second water path 50A is used for delivering water from the water source, and the pressurizing structure 120 and/or the turbulence structure 21 are/is disposed on the second water path 50A, so that the pressurizing structure 120, the turbulence structure 21 and the like can be prevented from contacting the washing powder to a certain extent.

It is understood that the first waterway 40A and the second waterway 50A are used for circulating fluid, and the detergent mixed solution, the water solution, etc. are all fluids.

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, 5 and 13, the 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 in the first waterway 40A and the second waterway 50A may be increased.

In one embodiment, referring to fig. 10 to 12, 6, 19 and 26, the laundry treating apparatus includes a mixing space 20a, and the first water outlet 40Aa and the second water outlet 50Aa are both communicated with the mixing space 20 a. The fluid discharged from the second water outlet end 50Aa and the fluid discharged from the first water outlet end 40Aa are both introduced into the mixing space 20a to be converged and mixed, thereby enhancing the mixing effect and enabling the detergent, such as the washing powder, to be more sufficiently dissolved. The fluid within the mixing space 20a includes, but is not limited to, a detergent mixed solution of detergent and aqueous liquid.

It should be noted that, the first water outlet end 40Aa may be understood as a junction between the first water path 40A and the mixing space 20A. The second water outlet 50Aa may also be understood as the junction between the second water path 50A and the mixing space 20A. The mixing space 20a may be a chamber formed in a solid structure.

In one embodiment, the fluid discharged from the second water outlet end 50Aa and the fluid discharged from the first water outlet end 40Aa may meet in the laundry treating chamber. The laundry treating apparatus may have no mixing space 20a, and the fluid discharged from the second water outlet end 50Aa and the fluid discharged from the first water outlet end 40Aa directly meet in the air, and the meeting area is located in the laundry treating chamber. Thus, the fluid discharged from the second water outlet end 50Aa and the fluid discharged from the first water outlet end 40Aa promote dissolution of the detergent such as washing powder. Because the intersection area is located in the clothes treating cavity, the distance from the intersection area to the clothes to be treated, from which the mixed fluid of the first waterway 40A and the second waterway 50A is put, can be shortened, the foam breaking degree is reduced, foam detergent is put into the clothes to be treated, and the cleaning effect is improved.

In one embodiment, referring to fig. 2, 10, 12, 15 and 26, the mixing space 20a has a liquid outlet 20ab, and the liquid outlet 20ab is directly communicated with the laundry treating chamber. The liquid outlet 20ab is for discharging the fluid in the mixing space 20 a.

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

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.

In one embodiment, the liquid outlet 20ab may also be connected to the transit passage. That is, the fluid from the fluid 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 an embodiment, referring to fig. 12, 19 and 26, a plane where the liquid outlet 20ab is located is taken as a projection plane, and a projection of the second water outlet 50Aa is located within a projection range of the liquid outlet 20 ab. In this way, the fluid flow direction change caused by the dislocation of the water outlet end of the fluid flow channel 130a and the liquid outlet 20ab can be avoided.

In one embodiment, referring to fig. 12 and 20, the laundry treating apparatus includes a pressurizing structure 120, the second waterway 50A is provided with the pressurizing structure 120, and the pressurizing structure 120 is used to increase the flow rate of the fluid in the second waterway 50A. Illustratively, the pressurization structure 120 is disposed in the flow channel 130A of the second waterway 50A.

In this embodiment, the pressurizing structure 120 accelerates the fluid in the second waterway 50A, the fluid conveyed by the first waterway 40A and the fluid conveyed by the second waterway 50A are converged and mixed in the mixing space 20A, and the mixed fluid is discharged from the liquid outlet 20ab and enters the laundry treating chamber to participate in laundry treatment. The flow rate difference exists between the fluid in the first waterway 40A and the fluid in the second waterway 50A, for example, the flow rate of the fluid in the second waterway 50A is increased through the pressurizing structure 120, the flow rate of the second water outlet end 50Aa is larger than that of the first water outlet end 40Aa, and the flow rate of the two fluids entering the mixing space 20A is fast or slow, wherein the fast one can generate impact and disturbance on the slow one, so that the two fluids can be better mixed when meeting, and the dissolution of the detergent is further promoted. Of course, the fluid conveyed by the first waterway 40A and the fluid conveyed by the second waterway 50A may be intersected in the air, and the flow rate of the second water outlet end 50Aa is greater than that of the first water outlet end 40Aa, so that the two fluids are better mixed when being intersected, and the dissolution of the detergent is further promoted.

In one embodiment, referring to fig. 12 and 20, 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 of the first water outlet end 40Aa is sucked under the negative pressure effect and is mixed with the fluid of the second waterway 50A, 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. 12 and 20, 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 second waterway 50A is directly ejected 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. 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. 12 and 20, the laundry treating apparatus includes a turbulence structure 21, the turbulence structure 21 being disposed in the second waterway 50A for providing a circumferential velocity component to the fluid in the second waterway 50A. Illustratively, the turbulator structure 21 is disposed in the flow channel 130a.

The above-mentioned provision of the circumferential velocity component means that the fluid passing through the turbulent structure 21 in the second waterway 50A has a velocity component in the circumferential direction of the second waterway 50A other than zero, and the circumferential direction of the second waterway 50A surrounds the extending direction of the second waterway 50A.

After passing through the turbulent flow structure 21, the fluid in the second waterway 50A 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 liquid 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 structure 21 may also cause an increase in the flow rate of the fluid by limiting the area of the second waterway 50A in which it is 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 FIGS. 12 and 20, turbulence structures 21 include one or more helical blades for guiding the helical motion of the fluid in second waterway 50A. 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 second waterway 50A into a plurality of sub-flow passages.

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. 12 and 20, the outer edge of the spiral blade along the spiral direction is connected to the inner wall of the second waterway 50A, and the inner edge of the spiral blade along the spiral direction is spaced from the inner wall of the second waterway 50A. I.e. the inner edges of the helical blades are in clearance with the inner wall of the second waterway 50A, so that the inner wall of the second waterway 50A provides connection support for the helical blades.

In one embodiment, referring to FIGS. 12 and 20, 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, e.g., the reduced diameter section 22, and then is ejected into the laundry treating chamber with a tapered shape.

In one embodiment, referring to fig. 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, referring to fig. 3 to 26, the laundry treating apparatus includes a spray head 130, where the spray head 130 is formed with a diversion channel 130b and a flow channel 130A, the diversion channel 130b is a part of the first waterway 40A, the water outlet end of the diversion channel 130b is the first water outlet end 40Aa, the flow channel 130A is a part of the second waterway 50A, and the water outlet end of the flow channel 130A is the second water outlet end 50Aa. The diversion channel 130b delivers the detergent mixture solution and the flow channel 130a delivers the aqueous solution. By forming a part of the first waterway 40A and a part of the second waterway 50A using the spray head 130, it is possible to reduce the number of pipes for the laundry treating apparatus and reduce the difficulty of manufacturing.

In one embodiment, the flow rate of the water outlet end of the flow channel 130a is greater than the flow rate of the water outlet end of the flow guiding channel 130 b. On the one hand, the flow rate difference exists between the fluid discharged from the flow channel 130a and the fluid discharged from the flow guiding channel 130b, the flow rate at the water outlet end of the flow channel 130a is relatively large, so that the impact force of the fluid can be increased, the flow rates of the two fluids entering the mixing space 20a are fast and slow, the fast flow rate can impact and disturb the slow flow rate, so that the two fluids can be better mixed when being intersected, and the dissolution of the detergent is further promoted. On the other hand, the flow velocity of the water outlet end of the flow channel 130a is relatively large, and a negative pressure can be generated in the surrounding area, so that the fluid at the water outlet end of the flow guide channel 130b is pumped under the negative pressure, and the mixing effect is improved.

In some embodiments, referring to FIGS. 12 and 20, the pressurization structure 120 and/or the turbulence structure 21 are disposed in the flow channel 130a.

In one embodiment, referring to fig. 12, 25 and 26, the nozzle 130 is formed with a mixing space 20a. That is, the fluid of first waterway 40A and the fluid of second waterway 50A are all mixed in the spray head 130.

In one embodiment, referring to fig. 10 to 12, the spray head 130 includes a housing 132 and a cannula 131, the housing 132 forming a flow guide channel 130b and a mixing space 20a, the cannula 131 forming a flow channel 130a, at least a portion of the cannula 131 being inserted into the mixing space 20 a. That is, the second water outlet 50Aa is formed at the insertion tube 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 one embodiment, referring to fig. 10 to 12, the port of the cannula 131 facing the first direction is a second water outlet end 50Aa, and the first water outlet end 40Aa is formed on a sidewall of the mixing space 20a along the second direction, and the first direction and the second direction intersect. 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 20 a.

In one embodiment, referring to fig. 10 to 12, the housing 132 is formed with a liquid outlet 20ab.
