An embodiment of the present application provides a spray head 130, where the spray head 130 is used in a laundry treating apparatus, referring to fig. 10 to 26, the spray head 130 has a liquid flow channel 130a and a liquid outlet channel 130b, and 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 turbulence structure 21. The pressurization structure 120 is used to increase the flow velocity of the fluid, and the turbulence structure 21 is used to provide a circumferential velocity component to the fluid.

Taking the case where the liquid outlet passage 130b is provided with the pressurizing structure 120 and the turbulence structure 21 as an example, the pressurizing structure 120 serves to increase the flow velocity of the fluid in the liquid outlet passage 130b, and the turbulence structure 21 serves to provide a circumferential velocity component to the fluid in the liquid outlet passage 130 b.

Taking the case where the flow channel 130a is provided with the pressurizing structure 120 and the turbulent structure 21 as an example, the pressurizing structure 120 serves to increase the flow velocity of the fluid in the flow channel 130a, and the turbulent structure 21 serves to provide a circumferential velocity component to the fluid in the flow channel 130 a.

Taking the case where the flow channel 130a is provided with the turbulence structure 21 as an example, the above-mentioned provision of the circumferential velocity component means that the velocity component of the fluid passing through the turbulence structure 21 in the flow channel 130a in the circumferential direction of the flow channel 130a is not zero, and the circumferential direction of the flow channel 130a surrounds the extending direction of the flow channel 130 a. The fluid in the flow channel 130a, after passing through the turbulence structure 21, generates a multi-directional compound motion in the circumferential direction, the advancing direction, and the like. 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.

It is understood that, in the case where the liquid outlet channel 130b is provided with the turbulence structure 21, the principle is similar to that described above, and will not be repeated here.

The fact that at least one of the liquid flow channel 130a and the liquid outlet channel 130b is provided with the pressurizing structure 120 and/or the turbulence 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 turbulence structure 21.

In one embodiment, the liquid flow channel 130a is provided with one of the pressurizing structure 120 and the turbulence structure 21, and the liquid flow channel 130b is not provided with the pressurizing structure 120 and the turbulence structure 21.

In one embodiment, the liquid flow channel 130a is provided with two of the pressurizing structure 120 and the turbulence structure 21, and the liquid flow channel 130b is not provided with the pressurizing structure 120 and the turbulence structure 21.

In one embodiment, the liquid outlet channel 130b is provided with one of the pressurizing structure 120 and the turbulence structure 21, and the liquid outlet channel 130a is not provided with the pressurizing structure 120 and the turbulence structure 21.

In one embodiment, the liquid outlet channel 130b is provided with two of the pressurizing structure 120 and the turbulence structure 21, and the liquid outlet channel 130a is not provided with the pressurizing structure 120 and the turbulence structure 21.

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

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

The embodiments of the pressurizing structure 120 and the turbulent structure 21 provided in the liquid flow channel 130a and the liquid flow channel 130b are exemplarily illustrated above, and those skilled in the art can obtain other embodiments according to the above examples, which are not illustrated here.

At least one of the liquid flow channel 130a and the liquid outlet channel 130b is used for delivering the detergent mixed solution. For example, it may be that both the liquid flow channel 130a and the liquid outlet channel 130b deliver the detergent mixed solution. For another example, the liquid flow channel 130a carries a detergent mixture solution, while the liquid flow channel 130b carries other fluids. For another example, the liquid outlet channel 130b delivers a detergent mixture solution, while the liquid flow channel 130a delivers other fluids.

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 exemplary functions of the detergent include, but are not limited to, cleaning, softening, or flavoring.

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.

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 liquid flow channel 130a and the liquid outlet channel 130b are used for circulating fluid, and the detergent mixed solution, the water solution and the like belong to the fluid.

The fluid of the liquid flow channel 130a and the fluid of the liquid outlet channel 130b can meet, that is, the fluid of the liquid flow channel 130a and the fluid of the liquid outlet channel 130b can contact and mix.

According to the spray head provided by the embodiment of the application, the pressurizing structure 120 accelerates the fluid, the turbulence structure 21 provides a circumferential velocity component for the fluid, the turbulence structure 21 can enable the fluid to be in conical divergence, the fluid conveyed by the liquid outlet channel 130b and the fluid conveyed by the liquid flow channel 130a are converged and mixed, and the mixed fluid enters the clothes treatment cavity to participate in clothes treatment. The flow rate difference exists between the fluid in the liquid outlet channel 130b and the fluid in the liquid flow channel 130a, for example, the flow rate of the fluid in the liquid flow channel 130a is increased through the pressurizing structure 120 and/or the turbulence 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, wherein the one with the higher flow rate can impact and disturb the one with the lower flow rate, so that the two fluids can be better mixed when the two fluids meet, and the dissolution of the detergent is further promoted. That is, the spray head 130 may promote mixing of the solution and may also cause the fluid to diverge conically.

In one embodiment, the flow channel 130a delivers an aqueous solution and the outlet channel 130b delivers a detergent mixture solution. The aqueous liquid delivered from the liquid flow channel 130a can further promote dissolution of the detergent, such as washing powder, in the liquid flow channel 130 b.

An embodiment of the present application provides a laundry treating apparatus, referring to fig. 2, 10, 12, 15 and 26, which includes a laundry treating chamber and a spray head according to any one of the embodiments of the present application, and the liquid flow channel 130a and the liquid outlet channel 130b each deliver a fluid into the laundry treating chamber. The fluid output from the fluid channel 130a and the fluid output from the fluid channel 130b may meet in the air or in the mixing space 20 a. The fluid delivered by both the liquid flow channel 130a and the liquid outlet channel 130b is used for treating laundry.

It should be noted that, for convenience of description, the water outlet end of the liquid flow channel 130a is defined as the second water outlet end 50Aa, and the water outlet end of the liquid flow channel 130b is defined as the first water outlet end 40Aa. The flow channel 130a is provided with the pressurizing structure 120 and/or the turbulence structure 21, which will be described below.

In one embodiment, referring to fig. 12 and 26, the liquid outlet channel 130b has a first water outlet end 40Aa, the liquid flow channel 130a has a second water outlet end 50Aa, and the projection 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. 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.

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, and when the fluid channel 130b is in communication with the mixing space 20a, the first water outlet 40Aa may be understood as a junction between the fluid channel 130b and the mixing space 20 a. The second water outlet 50Aa refers to a portion of the fluid in the fluid channel 130a leaving the fluid channel 130a, and in the case that the fluid channel 130b communicates with the mixing space 20a, the second water outlet 50Aa may be understood as a junction between the fluid channel 130a and the mixing space 20 a.

The axis of the first water outlet end 40Aa is a straight line passing through the center point of the flow cross section of the first water outlet end 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. The liquid outlet 20ab is a water outlet end of the mixing space 20a, and an axis of the liquid outlet 20ab is a straight line passing through a center point of a flow cross section of the liquid outlet 20 ab.

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 channel 130a is provided with a pressurizing structure 120 and/or a turbulence structure 21, and the flow rate of the second water outlet end 50Aa is greater than that of the first water outlet end 40 Aa. On the one hand, the flow rate difference exists between the fluid discharged from the liquid flow channel 130a and the fluid discharged from the liquid flow channel 130b, and the flow rate of the second water outlet end 50Aa is relatively high, so that the impact force of the fluid can be increased, wherein the one with the higher flow rate can generate impact and disturbance on the one with the lower flow rate, so that the two fluids can be better mixed when meeting, and the dissolution of the detergent is further promoted. On the other hand, the flow rate of the second water outlet end 50Aa is relatively large, and a negative pressure can be generated in the surrounding area, so that the fluid of the first water outlet end 40Aa is sucked under the negative pressure, and the mixing effect is improved.

In this embodiment, the fluid is flowed through both the fluid outlet channel 130b and the fluid outlet channel 130a, the fluid flowing through the fluid outlet channel 130b is sprayed out along the axis of the first water outlet end 40Aa, the fluid flowing through the fluid outlet channel 130a is sprayed out 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 sprayed out of the first water outlet end 40Aa and the fluid sprayed out of the second water outlet end 50Aa can meet, and when the two fluids meet, the two fluids are mixed and impacted, so that the dissolution of the detergent can be further promoted, the detergent with bubbles can be put into the clothes, and the cleaning effect can be improved.

In one embodiment, referring to fig. 12, 25 and 26, the nozzle 130 is formed with a mixing space 20a, and the liquid flow channel 130a and the liquid outlet channel 130b are both communicated with the mixing space 20 a. That is, the first and second water outlet ends 40Aa and 50Aa are both communicated with the mixing space 20 a. The fluid in the fluid channel 130a and the fluid in the fluid channel 130b both enter the mixing space 20a and mix in the nozzle 130.

In this embodiment, the pressurizing structure 120 accelerates the fluid in the fluid channel 130a, the turbulence structure 21 provides a circumferential velocity component to the fluid in the fluid channel 130a, and there is a difference in flow velocity between the fluid in the fluid channel 130b and the fluid in the fluid channel 130a, and the two flows entering the mixing space 20a have a first speed and a second speed, wherein the one having the first speed can impact and disturb the one having the second speed, so as to promote the mixing effect, and make the detergent, such as the washing powder, dissolve more sufficiently.

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

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, 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 air, and the meeting area may be located in the laundry treating chamber. The spray head may be devoid of mixing space 20a, and the fluid discharged from second water outlet end 50Aa and the fluid discharged from first water outlet end 40Aa directly meet in the air, with the meeting area being 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. 10 to 12, 19 and 26, the nozzle 130 has a liquid outlet 20ab communicating with the mixing space 20 a. 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.

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. The pressurizing structure 120 accelerates the fluid in the fluid channel 130a, the turbulence structure 21 provides a circumferential velocity component for the fluid in the fluid channel 130a, the fluid conveyed by the fluid channel 130b and the fluid conveyed by the fluid channel 130a meet and mix in the mixing space 20a, and the mixed fluid is discharged from the fluid outlet 20ab and enters the laundry treatment chamber to participate in laundry treatment.

In one embodiment, referring to fig. 12, 19 and 26, the second water outlet 50Aa of the flow channel 130a 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. That is, the axis of the second water outlet end 50Aa is parallel to or coincident with the axis of the liquid outlet 20ab.

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. 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. 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 water outlet end of the fluid flow channel 130a and the liquid outlet 20ab can be avoided.

In one embodiment, referring to fig. 2, 10, 12, 15 and 26, 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.

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 one embodiment, 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 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 an embodiment, referring to fig. 12 and 20, the pressurizing structure 120 includes a reducing section 22, and the reducing section 22 increases the flow velocity of the water outlet end of the liquid flow channel 130a and/or the water outlet end of the liquid outlet channel 130b where the pressurizing structure 120 is located. Taking the example in which the flow channel 130a is provided with the pressurizing structure 120, the reduced diameter section 22 increases the flow rate of the second water outlet end 50Aa of the flow channel 130 a. Taking the example that the liquid outlet channel 130b is provided with the pressurizing structure 120, the reducing section 22 increases the flow velocity of the first water outlet end 40Aa of the liquid outlet channel 130 b.

In this embodiment, the reduced diameter section 22 refers to a flow direction of the fluid, and the flow area of the fluid in the reduced diameter section 22 becomes smaller. 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. Taking the case that the flow channel 130A is provided with the pressurizing structure 120 as an example, 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 FIGS. 12 and 20, the turbulence structure 21 includes one or more helical blades for guiding the fluid in a helical motion. Taking the example where the flow channel 130a is provided with the turbulence structure 21, the helical blade is used to guide the fluid in the flow channel 130a to spiral. 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 in the spiral direction is connected to the inner wall of the flow channel 130a, and the inner edge of the spiral blade in 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 some embodiments, the outer edge of the spiral blade in the spiral direction is connected to the inner wall of the liquid outlet channel 130b, and the inner edge of the spiral blade in the spiral direction is spaced apart from the inner wall of the liquid outlet channel 130 b. I.e. the inner edges of the spiral blades are in a gap with the inner wall of the liquid outlet channel 130b, such that the inner wall of the liquid outlet channel 130b provides a connection support for the spiral blades.

In one embodiment, referring to fig. 12 and 20, the pressurizing structure 120 and the turbulent structure 21 are disposed in the same channel, and the pressurizing structure 120 is located downstream of the turbulent structure 21.

For another example, the pressurizing structure 120 and the turbulence structure 21 are provided in the same liquid outlet channel 130 b.

In this embodiment, the fluid is sequentially passed through the turbulence structure 21, the pressurizing structure 120, such as the reduced diameter section 22, and then 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. 10 to 12, the spray head 130 includes a housing 132 and a cannula 131, the housing 132 forming a liquid channel 130b and a mixing space 20a, the cannula 131 forming a liquid channel 130a, at least a portion of the cannula 131 being inserted into the mixing space 20 a.

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.

For another example, the second water path 50A is used to circulate a detergent mixture solution, and the first water path 40A is used to circulate other fluid.

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.

In this embodiment, 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, etc. can be prevented from contacting the washing powder to some extent.

In one embodiment, referring to fig. 12 to 26, the fluid in the first waterway 40A is discharged through the first water outlet 40Aa, and the fluid in the second waterway 50A is discharged through the second water outlet 50 Aa. 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 some embodiments, referring to fig. 3, 9 and 26, the laundry treating apparatus includes a dispenser box 140, the dispenser box 140 forming a detergent delivery chamber 140A, the detergent delivery chamber 140A communicating with the first waterway 40A. The detergent delivery chamber 140A is a part of the first waterway 40A. The detergent delivery chamber 140a is used for containing detergent. The detergent delivery chamber 140a may be adapted to contain powdered detergent, although the detergent delivery chamber 140a may be adapted to contain a detergent having flow characteristics, such as a laundry detergent. The detergent delivery chamber 140a is located upstream of the mixing space 20a, and the water flow impacts the detergent in the detergent delivery chamber to primarily dissolve the detergent to form a detergent mixed solution, which is then introduced into the mixing space 20 a.

The number of the detergent dispensing chambers 140a is not limited, and the number of the detergent dispensing chambers 140a may be one or more. Taking the plurality of detergent delivery cavities 140a as an example, the plurality of detergent delivery cavities 140a may be sequentially arranged in a direction perpendicular to the up-down direction, for example, the plurality of detergent delivery cavities 140a may be sequentially arranged in the left-right direction or the front-rear direction. Each of the detergent delivery chambers 140a may deliver detergents of different functions or the same function.

The discharge port 140b communicates with the detergent delivery chamber 140a and the mixing chamber 30d, and the detergent in the detergent delivery chamber 140a enters the mixing chamber 30d through the discharge port 140b, and the mixing chamber 30d is used for containing the detergent mixed solution. The first drain port 30b communicates with the mixing chamber 30d for draining the detergent mixed solution in the mixing chamber 30 d.

The detergent dispensing chamber 140A, the mixing chamber 30d, and the first drain port 30b constitute a part of the first waterway 40A. Fluid from the water source flows through the detergent delivery chamber 140A, the mixing chamber 30d, and the first drain outlet 30b, e.g., 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 detergent mixed solution, which flows to the mixing chamber 30d 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.

The fluid of the mixing chamber 30d may enter the laundry treating chamber after entering the mixing space 20 a. That is, the detergent mixed solution in the mixing chamber 30d finally enters the laundry treating chamber to treat laundry.

In this embodiment, at least two discharge ports 140b are communicated with the mixing chamber 30d so that the detergent in the plurality of detergent delivery chambers 140a can enter the mixing chamber 30d and be discharged to the laundry treating chamber through the mixing chamber 30d, and the waterway is simple.

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.
