Unless otherwise clearly indicated in the context, singular forms "a", "an" and "the" used here may also indicate that the singular forms include plural forms. Terms "include", "including", "contain" and "have" are inclusive, and thus specify presence of stated features, steps, operations, elements and / or components, but do not exclude presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. Method steps, processes and operations described here are not interpreted as requiring them to be performed in the described or illustrated specific order necessarily, unless their execution order is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0061] Although terms "first", "second", "third" or the like may be used here to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may be only intended to distinguish an element, component, region, layer or section from another region, layer or section. Unless clearly indicated in the context, terms such as "first", "second" or the like and other numerical terms do not imply an order or sequence when they are used here. Therefore, a first element, component, region, layer or section discussed below may be referred to as a second element, component, region, layer or section, without departing from the teaching of the exemplary implementations.

[0062] In order to facilitate descriptions, spatially relative relationship terms may be used here to describe a relationship of an element or feature relative to another element or feature as shown in the drawings; for example, these relative relationship terms are "interior", "exterior", "inner side", "outer side", "below", "under", "above", "over", etc. Such spatially relative relationship terms are intended to include different orientations of a device in use or operation in addition to orientations depicted in the drawings.

[0075] As shown in combination with FIG. 1 to FIG. 6, in some implementations of the disclosure, the first chamber 22 is formed with a first chamber inlet 221 and a first chamber outlet 222, the first chamber 22 is provided with multiple water baffles at interior of the first chamber 22, and at least a portion of the water baffles are configured to guide the washing water to flow from the first chamber inlet 221 to the first chamber outlet 222.

[0076] Specifically, the first water inlet pipe 41 is communicated with the first chamber inlet 221 to introduce washing water into the first chamber 22, and the washing water is mixed with the liquid detergent in the first chamber 22 to form a detergent-water solution. The first supply pipeline is communicated with the first chamber outlet 222 to discharge the detergent-water solution into the clothes treatment cavity 1041. A first water baffle 223 and a second water baffle 224 sequentially arranged along a flowing direction of the water flow are formed at the interior of the first chamber 22. The first water baffle 223 is arranged opposite to the first chamber inlet 221 and is configured to guide the washing water to the first liquid-out end 241 and the second liquid-out end 242, so as to impact the detergent in the first chamber 22, such that the detergent is fully dissolved with the washing water. The second water baffle 224 is arranged in a direction of facing toward the first chamber outlet 222, so as to guide a mixed solution of the detergent and the washing water to flow to the first chamber outlet 222 and flow to the clothes treatment cavity 1041 through the first supply pipeline.

[0077] As shown in combination with FIG. 1 to FIG. 6, in some implementations of the disclosure, the first chamber 22 is further provided with a pressure relief port 226 at the interior of the first chamber 22, and the at least one water baffle is configured to guide washing water to flow from the first chamber inlet 221 to the pressure relief port 226.

[0078] Specifically, a first water baffle 223, a second water baffle 224 and a third water baffle 225 sequentially arranged along a flowing direction of the water flow are formed at the interior of the first chamber 22. The first water baffle 223 and the second water baffle 224 are configured to sequentially guide the washing water to flow to the first chamber outlet 222, and the third water baffle 225 is arranged in a water outlet direction of the second water baffle 224 and is configured to block a water flow flowing to the first chamber outlet 222 to a certain extent. With the blockage of the third water baffle 225, a portion of the solution flows to the pressure relief port 226, thereby reducing occurrence of a phenomenon that when there is a too high pressure in the first chamber 22, all the mixed solution of the detergent and the washing water flows to the first chamber outlet 222, resulting in that there is a too high pressure in the first supply pipeline, further resulting in damage to the first supply pipeline. The pressure relief port 226 is set to open when there is a too high pressure in the first chamber 22, and a specific pressure for opening the pressure relief port may be set based on a bearing pressure of the first supply pipeline.

[0079] As shown in combination with FIG. 1 to FIG. 6, in some implementations of the disclosure, the second chamber 23 includes a first communication section 231 and a second communication section 232, the first communication section 231 is arranged upstream of the second communication section 232, and the second communication section 232 is provided with conduction ports 235 communicated with the detergent cavity.

[0080] Specifically, the second communication section 232 may be configured to store the solid detergent. Since the first communication section 231 is arranged upstream of the second communication section 232, and the second pipeline assembly is communicated with the first communication section 231, a portion of the washing water entering the second chamber 23 through the second liquid supply pipe 50 is sprayed out through the second supply pipeline and is used for flushing the door glass of the door body 103. Another portion of the washing water may be introduced into the second communication section 232 and fall into the second detergent cavity through conduction holes, to dissolve the solid detergent. The dissolved detergent may enter a water storage cavity between a drum and a tub to wash the clothes. The water inlet valve 40 may control the first liquid supply pipe 30 and the second liquid supply pipe 50 to allow water to enter the first liquid supply pipe 30 and the second liquid supply pipe 50 together, or the water inlet valve 40 may control the first liquid supply pipe 30 and the second liquid supply pipe 50 to allow water to enter the first liquid supply pipe 30 and the second liquid supply pipe 50 separately, so as to implement different water supply modes and different detergent supply modes.

[0081] As shown in combination with FIG. 3 to FIG. 6, in some implementations of the disclosure, the first communication section 231 is provided with a second chamber outlet 237 configured to be communicated with a second supply pipeline.

[0082] Specifically, the second chamber 23 is formed with a second chamber inlet 236 and a second chamber outlet 237, the second chamber inlet 236 is communicated with the second water inlet pipe 42, the second chamber outlet 237 is arranged in a side wall of the first communication section 231 and is communicated with the second supply pipeline. In a process of the washing water flowing from the first communication section 231 to the second communication section 232, the washing water may flow to the second supply pipeline through the second chamber outlet 237 and is used for flushing the door glass.

[0083] As shown in combination with FIG. 3 to FIG. 6, in some implementations of the disclosure, at least one deflector is arranged between the second chamber inlet 236 and the second chamber outlet 237, and the deflector is configured to guide washing water to flow from the second chamber inlet 236 to the second chamber outlet 237.

[0084] Specifically, a first deflector 233 is arranged at interior of the first communication section 231, and the first deflector 233 is arranged between the second chamber inlet 236 and the second chamber outlet 237. The first deflector 233 is arranged in a direction of facing toward the second chamber outlet 237, and the washing water entering the first communication section 231 through the second chamber inlet 236 flows in the direction of facing toward the second chamber outlet 237 with a flow guidance effect of the first deflector 233, to facilitate the washing water to flow into the second supply pipeline through the second chamber outlet 237.

[0085] As shown in combination with FIG. 3 to FIG. 6, in some implementations of the disclosure, the first communication section 231 is provided with multiple deflectors at interior of the first communication section 231, and at least some of the deflectors are configured to guide the washing water to flow from the second chamber inlet 236 to the second communication section 232.

[0086] Specifically, a first deflector 233 and a second deflector 234 are arranged at interior of the first communication section 231, the first deflector 233 is arranged upstream of the second deflector 234, and the second chamber outlet 237 is arranged between the first deflector 233 and the second deflector 234. The first deflector 233 is arranged in a direction of facing toward the second chamber outlet 237, and the washing water entering the first communication section 231 through the second chamber inlet 236 flows in the direction of facing toward the second chamber outlet 237 with a flow guidance effect of the first deflector 233. The second deflector 234 is arranged in a direction of facing toward the second communication section 232, to facilitate that washing water which has not flowed into the second supply pipeline is guided to the second communication section 232 to flow into the second detergent cavity through the conduction ports 235.

[0087] As shown in combination with FIG. 3 to FIG. 6, in some implementations of the disclosure, the detergent box assembly 20 further includes a cover plate (not shown in the figures) and an enclosure plate 25, the cover plate and the enclosure plate 25 are arranged at the exterior of the box body 21, the enclosure plate 25 connects the cover plate to a top plate of the box body 21, and the first chamber 22 and the second chamber 23 are formed between the cover plate, the enclosure plate 25 and at least a portion of the top plate.

[0088] Specifically, the first chamber 22 and the second chamber 23 are arranged at the exterior of the box body 21 respectively. In a specific operation, the enclosure plate 25 and the cover plate may be arranged at an outer side of a top part of the box body 21 of the existing detergent box, and the cover plate may be connected to the top plate of the box body through the enclosure plate 25, such that a closed compartment is formed by the cover plate, the enclosure plate 25 and at least a portion of the top plate, and a partition is arranged at interior of the closed compartment to separate the closed compartment into the first chamber 22 and the second chamber 23. Furthermore, conduction ports 235 are arranged in the top plate and pass through the top plate, and the second chamber 23 is communicated with the second detergent cavity through the conduction ports 235. Since the first chamber 22 and the second chamber 23 are arranged at the exterior of the box body 21 respectively, the first chamber 22 and the second chamber 23 do not occupy original space at the interior of the box body 21, thereby reducing a situation where capacity of the detergent cavity is reduced.

[0089] As shown in combination with FIG. 1 to FIG. 6, in some implementations of the disclosure, the detergent box assembly 20 further includes a water passage (not shown in the figures), the water passage is arranged between the second chamber 23 and the top plate, and the first chamber 22 is communicated with the first supply pipeline through the water passage.

[0090] Specifically, since the first chamber 22 and the second chamber 23 are arranged at a top part of the box body 21 together, a water passage may be arranged between the second chamber 23 and the box body 21, and the first supply pipeline is communicated with the first chamber outlet 222 of the first chamber 22 through the water passage.

[0091] As shown in combination with FIG. 1 and FIG. 2, the detergent box assembly 20 and / or the first supply pipeline may be further provided with an intake structure, the intake structure is configured to introduce a gas at exterior of the detergent delivery device into the detergent delivery device, thereby increasing a gas content of the detergent in the detergent delivery device, further increasing a number of bubbles formed by the delivered detergent, increasing a contact area between the detergent and the clothes, improving utilization of the detergent, and enhancing the washing effect of the clothes. Furthermore, with bubbles formed by the delivered detergent, more foams may be generated by a large number of bubbles under impact, cleaning components are dispersed relatively, and the foams may cover more regions of the clothes, thereby increasing the contact area between the detergent and the clothes, improving the washing effect; a small amount of washing water may be introduced into the clothes treatment cavity 1041, then it is enough to wet the clothes, such that usage of the washing water may be effectively reduced compared to a conventional washing mode of introducing a large amount of washing water into the clothes treatment cavity 1041.

[0092] As shown in combination with FIG. 1 and FIG. 2, in some implementations of the disclosure, the first supply pipeline may be further provided with an intake structure, the intake structure is configured to introduce a gas at exterior of the first supply pipeline into the first supply pipeline, thereby increasing a gas content of the detergent in the first supply pipeline, further increasing a number of bubbles formed by the delivered detergent, increasing a contact area between the detergent and the clothes, improving utilization of the detergent, and enhancing the washing effect of the clothes.

[0093] Furthermore, with bubbles formed by the delivered detergent, more foams may be generated by a large number of bubbles under impact, cleaning components are dispersed relatively, and the foams may cover more regions of the clothes, thereby increasing the contact area between the detergent and the clothes, improving the washing effect; a small amount of washing water may be introduced into the clothes treatment cavity 1041, then it is enough to wet the clothes, such that usage of the washing water may be effectively reduced compared to a conventional washing mode of introducing a large amount of washing water into the clothes treatment cavity 1041.

[0094] As shown in combination with FIG. 2 and FIG. 7, in some implementations of the disclosure, the first supply pipeline includes a first liquid supply pipe 30 and a first nozzle 10, the first liquid supply pipe 30 and / or the first nozzle 10 is provided with an intake structure.

[0095] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the first nozzle 10 is communicated with the first detergent cavity 22 through the first liquid supply pipe 30. The intake structure communicated with an external environment is arranged on the first nozzle 10. The first nozzle 10 includes a pipe body 11 and a pipe cavity 12 arranged at interior of the pipe body 11, and the intake structure includes a suction hole 13, the suction hole 13 is arranged in a side wall of the pipe body 11 and communicates the interior of the pipe body 11 with exterior of the pipe body 11. A gas at the exterior of the pipe body 11 may enter the pipe cavity 12 through the suction hole 13, to increase a gas content in the pipe cavity 12, and further increase a gas content of the detergent and / or washing water in the pipe cavity 12.

[0096] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the pipe cavity 12 includes a first pipe cavity section 121, a second pipe cavity section 122 and a third pipe cavity section 123 communicated in sequence, a circulation area of the first pipe cavity section 121 gradually decreases along a direction from the first pipe cavity section 121 to the second pipe cavity section 122, a circulation area of the third pipe cavity section 123 gradually increases along a direction from the second pipe cavity section 122 to the third pipe cavity section 123, and the suction hole 13 is arranged in the side wall of the pipe body 11 and communicates the interior of the pipe body 11 with the exterior of the pipe body 11.

[0097] With the first pipe cavity section 121, the second pipe cavity section 122 and the third pipe cavity section 123 arranged based on the above structures, a structure similar to a Venturi pipe is formed at interior of the pipe cavity 12, and a Venturi effect may be generated correspondingly. The Venturi effect refers to: when a fluid passes through a narrow part of a pipe, velocity of the fluid at the narrow part of the pipe increases, and static pressure at the narrow part of the pipe decreases. Since the second pipe cavity section 122 is narrower than the first pipe cavity section 121 and the third pipe cavity section 123, the suction hole 13 is communicated with the second pipe cavity section 122, then when a fluid circulates in the pipe cavity 12, for example, when the detergent and / or washing water circulates in the pipe cavity 12, the gas at the exterior of the pipe body 11 may enter the pipe cavity 12 through the suction hole 13 with an action of the Venturi effect in the pipe cavity 12, thereby increasing the gas content of the detergent and / or washing water in the pipe cavity 12, and further increasing a number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10, increasing a contact area between the detergent and / or washing water and the clothes, improving the washing effect of the clothes.

[0098] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, a communication cavity 14 is further arranged in the side wall of the pipe body 11, and the suction hole 13 is communicated with the second pipe cavity section 122 through the communication cavity 14.

[0099] With the communication cavity 14 arranged to communicate the suction hole 13 with the second pipe cavity section 122, it may prevent the fluid flowing through the second pipe cavity section 122 from flowing out to exterior of the pipe body 11 through the suction hole 13, by setting a circulation area and circulation path of the communication cavity 14.

[0100] Specifically, in some implementations of the disclosure, the communication cavity 14 includes a first communication part 141 and a second communication part 142, and the second pipe cavity section 122, the first communication part 141, the second communication part 142 and the suction hole 13 are communicated in sequence, and along an axial direction of the second pipe cavity section 122, a size L1 of the first communication part 141 is less than a size L2 of the second communication part 142, less than a size L3 of the suction hole 13, and less than a size L4 of the second pipe cavity section 122 respectively.

[0101] That is, an end of the communication cavity 14 close to the second pipe cavity section 122 is provided with a minimum opening size, to prevent the fluid in the second pipe cavity section 122 from flowing out to the exterior of the pipe body 11 by passing through the communication cavity 14 and the suction hole 13 in sequence. Furthermore, since the size L1 of the first communication part 141 is less than the size L2 of the second communication part 142, a bent structure is formed, which prevents the fluid in the second pipe cavity section 122 from flowing out to the exterior of the pipe body 11 by passing through the communication cavity 14 and the suction hole 13 in sequence, in some implementations.

[0102] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, an opening area of the suction hole 13 may be consistent with a circulation area of the second pipe cavity section 122, thereby increasing an intake volume in the pipe cavity 12.

[0103] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, along the axial direction of the second pipe cavity section 122, a projection of the first communication part 141 and a projection of the second communication part 142 are in a partial ring shape respectively, a value range of a central angle a corresponding to the projection of the first communication part 141 is 0° < a ≤ 180°, and / or a value range of a central angle b corresponding to the projection of the second communication part 142 is 0° < b ≤ 180°.

[0104] That is, the first communication part 141 may be in a fan-shaped structure or a semicircular ring structure, and / or the second communication part 142 may be in a fan-shaped structure or a semicircular ring structure, thereby increasing a circulation area of the communication cavity 14, and further increasing the intake volume in the pipe cavity 12.

[0105] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the central angle a corresponding to the projection of the first communication part 141 takes a value of 180°, the central angle b corresponding to the projection of the second communication part 142 takes a value of 180°, the second pipe cavity section 122 is a circular pipe cavity section, a diameter R of the second pipe cavity section 122 is consistent with the size L4 of the second pipe cavity section 122 along the axial direction, the second pipe cavity section 122 has a circulation area S1, and the first communication part 141 has a minimum circulation area S2, here S1 is greater than S2.

[0106] Specifically, the first communication part 141 and the second communication part 142 are in a semicircular structure respectively. With S1 set to be greater than S2, the circulation area of the first communication part 141 is less than the circulation area of the second pipe cavity section 122, thereby reducing occurrence of a phenomenon that the fluid in the second pipe cavity section 122 flows out to the exterior of the pipe body 11 by passing through the first communication part 141 and the suction hole 13.

[0107] Specifically, a ratio of S1:S2 is 4:1. The diameter of the second pipe cavity section 122 is R, the circulation area of the second pipe cavity section 122 is S1=πR2, an arc length of the first communication part 141 is πR, the size of the first communication part 141 along the axial direction is L1, and the circulation area of the first communication part 141 is S2=πRL1. Since the ratio of S1:S2 is 4:1, a ratio of R to L1 is 4:1. Furthermore, since the size L4 of the second pipe cavity section 122 along the axial direction is equal to the diameter of the second pipe cavity section 122, and both of them are R, then L4 is equal to four times of L1.

[0108] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the suction hole 13 is a circular hole, and a value range of the diameter L3 of the suction hole 13 is 2 mm ≤ L3 ≤ 3.6 mm.

[0109] Since in some implementations of the disclosure, the opening area of the suction hole 13 is consistent with the circulation area of the second pipe cavity section 122, R may be consistent with the value of L3, that is, 2 mm ≤ R ≤ 3.6 mm. Furthermore, since in some implementations of the disclosure, the size L4 of the second pipe cavity section 122 along the axial direction is equal to the diameter R of the second pipe cavity section 122, 2 mm ≤ L4 ≤ 3.6 mm.

[0110] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, an end of the third pipe cavity section 123 away from the second pipe cavity section 122 is provided with a liquid outlet 17 communicated with the pipe cavity 12, and an axis of the suction hole 13 is set at an angle of 90° to 180° with an axis of the liquid outlet 17.

[0111] That is, along a circumferential direction of the second pipe cavity section 122, the liquid outlet 17 and the suction hole 13 are arranged to space apart at an angle of 90° to 180°, thereby reducing occurrence of a phenomenon that the fluid flows into the suction hole 13 with an action of airflow after flowing out through the liquid outlet 17. Specifically, the angle between the liquid outlet 17 and the suction hole 13 may be any angle value between 90°...120°...150°...180°. When the liquid outlet 17 and the suction hole 13 are arranged to space apart at an angle of 180°, occurrence of the phenomenon that the fluid flows into the suction hole 13 with an action of airflow after flowing out through the liquid outlet 17 may be reduced to a maximum extent.

[0112] As shown in combination with FIG. 2 and FIG. 7 to FIG. 9, in some implementations of the disclosure, a fixing part 15 is further arranged on and protruded from an outer surface of the pipe body 11, and the liquid outlet 17 and the suction hole 13 are arranged at the same side of the fixing part 15 together along the axial direction of the second pipe cavity section 122.

[0113] Specifically, the fixing part 15 is configured to fix an overall installation position of the first nozzle 10. Since the clothes treatment drum 104 may rotate in a process of washing the clothes, it is not suitable for the first nozzle 10 to pass through the clothes treatment drum 104 and plug into the clothes treatment cavity 1041 directly. In some implementations of the disclosure, the first nozzle 10 may be arranged on a door seal 105 at the front end of the clothes treatment drum 104, and the front end of the clothes treatment drum 104 is an end facing toward the door body 103. The fixing part 15 is clamped at interior of the door seal 105, to allow an end of the first nozzle 10 provided with the liquid outlet 17 to pass through the door seal 105 to be arranged to face toward the interior of the clothes treatment cavity 1041, the first nozzle 10 delivers the detergent into the clothes treatment cavity 1041 by spraying the detergent, and another end of the first nozzle 10 is arranged at exterior of the door seal 105 and is configured to be communicated with the first liquid supply pipe 30. The liquid outlet 17 and the suction hole 13 are arranged at the same side of the fixing part 15 facing toward the clothes treatment cavity 1041 together, that is, the liquid outlet 17 and the suction hole 13 are arranged at an inner side of the door seal 105 communicated with the clothes treatment cavity 1041 together. Even though a fluid leakage phenomenon occurs at the suction hole 13, the leaked fluid may not fall onto other electrical components at exterior of the clothes treatment drum 104, thereby reducing occurrence of safety accidents.

[0114] In some implementations of the disclosure, a maximum distance between the suction hole 13 and the fixing part 15 is less than a minimum distance between the liquid outlet 17 and the fixing part 15.

[0115] When the first nozzle 10 is mounted at the interior of the clothes treatment apparatus 1, the first nozzle 10 is arranged substantially along a vertical direction, or arranged at an angle with the vertical direction. In the vertical direction, the liquid outlet 17 is arranged at a lowermost end of the first nozzle 10, the suction hole 13 is arranged above the liquid outlet 17, the fixing part 15 is arranged above the suction hole 13, and the maximum distance between the suction hole 13 and the fixing part 15 is less than the minimum distance between the liquid outlet 17 and the fixing part 15, that is, any position on the suction hole 13 may not be located below the liquid outlet 17, thereby reducing occurrence of the phenomenon that the fluid flows into the suction hole 13 with an action of airflow after flowing out through the liquid outlet 17.

[0116] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the pipe cavity 12 further includes a fourth pipe cavity section 124, the fourth pipe cavity section 124 is arranged at an end of the first pipe cavity section 121 away from the second pipe cavity section 122, and the fourth pipe cavity section 124 is provided with a liquid inlet 16 communicated with the pipe cavity 12.

[0117] Specifically, the liquid inlet 16 is arranged at a top part of the fourth pipe cavity section 124, and the first nozzle 10 is communicated with the first liquid supply pipe 30 through the liquid inlet 16, to transport the fluid into the pipe cavity 12. The fourth pipe cavity section 124 is usually a straight pipe cavity section, to facilitate transportation of the fluid, or facilitate arrangement of other structures at interior of the fourth pipe cavity section 124.

[0118] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, a flow disturbance structure 18 is further arranged in the pipe cavity 12, such that the fluid flowing through the flow disturbance structure 18 in the pipe cavity 12 has a component velocity along a circumferential direction of the pipe cavity 12.

[0119] With the flow disturbance structure 18 arranged in the pipe cavity 12 of the first nozzle 10 such that the fluid flowing through the flow disturbance structure 18 in the pipe cavity 12 has a component velocity along the circumferential direction of the pipe cavity 12, after the fluid flows out through the pipe cavity 12, for example, after the detergent and / or washing water flows out through the pipe cavity 12, the component velocity of the fluid along the circumferential direction of the pipe cavity 12 may increase an angle of spraying the fluid, thereby increasing an area sprayed by the first nozzle 10, and further increasing the contact area between the detergent and / or washing water and the clothes, improving utilization of the detergent and / or washing water, and improving the washing effect of the clothes.

[0120] Specifically, the flow disturbance structure 18 may be arranged at the interior of the fourth pipe cavity section 124. In a process of the fluid flowing in the pipe cavity 12, a component velocity of the fluid along the circumferential direction of the pipe cavity 12 is formed first with an action of the flow disturbance structure 18, then a gas content in the fluid is increased through a function of supplementing gas by the suction hole 13; when the fluid is sprayed from the liquid outlet 17, the angle of spraying the fluid may be diffused along the circumferential direction of the pipe cavity 12, while a large number of bubble structures are formed, thereby effectively increasing a contact area between a medium and the clothes, such as the contact area between the detergent and / or washing water and the clothes, improving utilization of the detergent and / or washing water, and improving the washing effect of the clothes.

[0121] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the flow disturbance structure 18 includes at least one flow disturbance plate 181, and a plate surface of the flow disturbance plate 181 is arranged at an angle with an axial direction of the pipe cavity 12. Since the plate surface of the flow disturbance plate 181 is arranged at an angle with the axial direction of the pipe cavity 12, when the fluid flows through the flow disturbance plate 181, the fluid may flow along a direction of the plate surface of the flow disturbance plate 181 with an action of the flow disturbance plate 181, such that a flowing direction of the fluid is set at an angle with the axial direction of the pipe cavity 12, and thus the fluid has a component velocity along the circumferential direction of the pipe cavity 12.

[0122] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the flow disturbance structure 18 includes multiple flow disturbance plates 181, and the multiple flow disturbance plates 181 are arranged at intervals along the circumferential direction of the pipe cavity 12, and an angle between the plate surface of any one of the flow disturbance plates 181 and the axial direction of the pipe cavity 12 is the same.

[0123] With multiple flow disturbance plates 181 arranged simultaneously, a flow disturbance effect of the flow disturbance structure 18 may be improved, thereby increasing an angle of diffusing and spraying the detergent and / or washing water along the circumferential direction of the pipe cavity 12 after the detergent and / or washing water is sprayed out from the liquid outlet 17, increasing the contact area between the detergent and / or washing water and the clothes, improving utilization of the detergent and / or washing water, and improving the washing effect of the clothes.

[0124] As shown in combination with FIG. 7 to FIG. 9, in some implementations of the disclosure, the flow disturbance structure 18 further includes a connection ring 182, the connection ring 182 is provided with a first through hole 183 passing through the connection ring 182 along the axial direction of the pipe cavity 12, and an end of each of multiple flow disturbance plates 181 is connected to an outer circumferential surface of the connection ring 182 respectively.

[0125] Specifically, an end of each of the multiple flow disturbance plates 181 is connected to the connection ring 182 respectively, and another end of each of the multiple flow disturbance plates 181 is connected to an inner wall of the pipe cavity 12 respectively. The multiple flow disturbance plates 181 are fixed by the connection ring 182 simultaneously, such that the multiple flow disturbance plates 181 are arranged at intervals along a circumferential direction of the connection ring 182, and the connection ring 182 is provided with a first through hole 183 passing through the connection ring 182 along the axial direction, such that the medium at the center of the pipe cavity 12 flows through the connection ring 182 through the first through hole 183, and the medium at a circumferential edge of the pipe cavity 12 has a component velocity along the circumferential direction of the pipe cavity 12 due to the flow disturbance effect of the flow disturbance plate 181.

[0126] In some implementations of the disclosure, structure of the connection ring 182 may also be removed, an end of each of the multiple flow disturbance plates 181 may be connected to an inner wall surface of the pipe cavity 12 respectively, and another end of each of the multiple flow disturbance plates 181 may be suspended in the air; similarly, the multiple flow disturbance plates 181 may be arranged at intervals along the circumferential direction of the pipe cavity 12.

[0127] As shown in FIG. 10, in some implementations of the disclosure, there are two flow disturbance plates 181, the two flow disturbance plates 181 are arranged at an interval along the circumferential direction of the pipe cavity 12, and the two flow disturbance plates 181 are staggered along the axial direction of the pipe cavity 12.

[0128] Specifically, an end of each of the two flow disturbance plates 181 is connected to the inner wall surface of the pipe cavity 12 respectively, and another end of each of the two flow disturbance plates 181 is arranged at an interval with the inner wall surface of the pipe cavity 12 respectively. The two flow disturbance plates 181 are oppositely arranged to space apart by 180°, and at least a portion of structure of one of the flow disturbance plates 181 is arranged above another one of the flow disturbance plates 181. When the fluid flows into the pipe cavity 12 through the liquid inlet 16, the fluid collides first with the flow disturbance plate 181 located above, thereby forming a component velocity along the circumferential direction of the pipe cavity 12. Then, in a falling process of the fluid, the fluid collides with the flow disturbance plate 181 located below, the component velocity of the fluid along the circumferential direction of the pipe cavity 12 is increased in some implementations.

[0129] In some implementations, in order to increase a probability of the fluid colliding with the two flow disturbance plates 181 in sequence while flowing through the pipe cavity 12, sizes of the two flow disturbance plates 181 along a radial direction of the pipe cavity 12 exceed a radius of the pipe cavity 12 respectively, that is, structures of the two flow disturbance plates 181 are partially overlapped along the axial direction of the pipe cavity 12.

[0130] As shown in FIG. 11, in some implementations of the disclosure, the flow disturbance structure 18 is connected to the inner wall surface of the pipe cavity 12, the flow disturbance structure 18 is formed with at least one flow disturbance channel 185, and an axial direction of the flow disturbance channel 185 is set at an angle with the axial direction of the pipe cavity 12.

[0131] Specifically, one or more flow disturbance channels 185 may be simultaneously arranged at the interior of the pipe cavity 12, and the axial direction of each of the flow disturbance channels 185 is set at an angle with the axial direction of the pipe cavity 12, such that in a process of the fluid flowing through the pipe cavity 12, the fluid may form a component velocity along the circumferential direction of the pipe cavity 12 when the fluid flows through the flow disturbance channels 185.

[0132] The flow disturbance structure 18 may include an installation block 184, an outer wall surface of the installation block 184 is arranged to fit the inner wall surface of the pipe cavity 12, the installation block 184 is provided with at least two flow disturbance channels 185 passing through the installation block 184, and the at least two flow disturbance channels 185 are arranged to intersect with each other.

[0133] With the outer wall surface of the installation block 184 arranged to fit the inner wall surface of the pipe cavity 12, there is no space for circulation of the fluid between the installation block 184 and the pipe cavity 12, such that the fluid in the pipe cavity 12 may flow out only through the flow disturbance channel 185, and thus most or even all of the fluid in the pipe cavity 12 forms a component velocity along the circumferential direction of the pipe cavity 12. Furthermore, the at least two flow disturbance channels 185 are arranged to intersect with each other, that is, the fluid flowing out of the flow disturbance channels 185 may flow out along different directions, thereby increasing a collision probability of the fluid after flowing out of the flow disturbance channels 185, and increasing the component velocity of the fluid along the circumferential direction of the pipe cavity 12 in some implementations.

[0134] As shown in combination with FIG. 7 to FIG. 11, the communication cavity 14 in the above implementations includes the first communication part 141 and the second communication part 142 respectively, to reduce a phenomenon that leakage of the pipe cavity 12 occurs through the suction hole 13. In some implementations of the disclosure, structure of the communication cavity 14 may also be simplified.

[0135] As shown in FIG. 12, in some implementations of the disclosure, the suction hole 13 is communicated with the second pipe cavity section 122 through the communication cavity 14. The communication cavity 14 may be a straight pipe cavity or a partially arcuate pipe cavity, thereby reducing arrangement of the first communication part 141 and the second communication part 142. The suction hole 13 may be a circular hole or a square hole, and a circulation area of the suction hole 13 gradually decreases along a direction from the exterior of the pipe body 11 to the interior of the pipe body 11, which may also reduce the phenomenon that leakage of the pipe cavity 12 occurs through the suction hole 13.

[0136] As shown in FIG. 12, in some implementations of the disclosure, an end of the first pipe cavity section 121 close to the second pipe cavity section 122 is inclined in a direction of facing toward the liquid outlet 17, such that in a process of the fluid flowing through the first pipe cavity section 121 to the second pipe cavity section 122, a component velocity of the fluid flowing in the direction of facing toward the liquid outlet 17 may be increased, thereby increasing an angle of spraying the fluid and increasing an area sprayed by the first nozzle 10.

[0141] With the first liquid supply section, the second liquid supply section and the third liquid supply section arranged based on the above structures, a structure similar to a Venturi pipe is formed at the interior of the first liquid supply pipe, and a Venturi effect may be generated correspondingly. Since the second liquid supply section is narrower than the first liquid supply section and the third liquid supply section, the communication hole is communicated with the second liquid supply section, then when a fluid circulates in the first liquid supply pipe 30, for example, when the detergent and / or washing water circulates in the first liquid supply pipe 30, the gas at the exterior of the first liquid supply pipe 30 may enter the first liquid supply pipe 30 through the communication hole with an action of the Venturi effect in the first liquid supply pipe 30, thereby increasing the gas content of the detergent and / or washing water in the first liquid supply pipe 30, and further increasing a number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10, increasing a contact area between the detergent and / or washing water and the clothes, improving the washing effect of the clothes.

[0143] Specifically, a gas at exterior of the detergent box assembly 20 may enter the first detergent cavity or the first chamber 22 through the communication hole, thereby increasing a gas content in the detergent delivery device 101, and further increasing a number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10, increasing a contact area between the detergent and / or washing water and the clothes, improving the washing effect of the clothes.

[0152] Specifically, washing water may enter the mixing cavity through the first liquid inlet 711, detergent in the detergent cavity may enter the mixing cavity through the second liquid inlet 712, the detergent and the washing water are mixed in the mixing cavity to form a mixed solution of the detergent and the washing water, and transport the mixed solution of the detergent and the washing water to the first liquid supply pipe 30 through the first liquid discharge port 713, such that the mixed solution of the detergent and the washing water is delivered into the clothes treatment cavity 1041 through the first nozzle 10. The first liquid inlet 711 may be communicated with the external water supply pipeline through the water inlet valve 40, and whether the washing water is injected into the mixing cavity is controlled by the water inlet valve 40. The water inlet valve 40 may also be communicated with other pipeline components and configured to supply water to other pipeline components. The second liquid inlet 712 may be communicated with the detergent cavity at the interior of the detergent box assembly 20 through the liquid pumping assembly 24, and the liquid pumping assembly 24 is configured to pump the detergent in the detergent cavity into the mixer 70.

[0153] The detergent and the washing water are mixed in the mixer 70 in advance and then discharged into the clothes treatment cavity 1041, which achieves a more uniform mixing effect and a more uniform contact area between the detergent and the clothes, compared to a situation where the detergent and the washing water are delivered into the clothes treatment cavity 1041 separately and then mixed, thereby improving the washing effect of the clothes. Furthermore, the detergent in the mixing cavity is subject to impact of the washing water, which may reduce residuals of the detergent in the mixing cavity and improve utilization rate of the detergent.

[0154] As shown in combination with FIG. 15 to FIG. 30, according to an implementation of the disclosure, there is provided a clothes treatment apparatus 1, the clothes treatment apparatus 1 includes a cabinet, a clothes treatment drum 104, a door body and a delivery assembly 90.

The door body is mounted on the cabinet and is pivotable relative to the cabinet, and an operation of opening or closing the delivery port may be achieved by pivoting the door body relative to the cabinet.

[0156] In some implementations of the disclosure, the delivery assembly 90 includes two delivery passages, that is, a first delivery passage and a second delivery passage. The first delivery passage is provided with a first inlet and a first outlet, the first inlet is configured to receive detergent solution or water, the first outlet is configured to spray the detergent solution or water into the clothes treatment cavity 1041, the second delivery passage is provided with a second inlet and a second outlet, the second inlet is configured to receive water, and the second outlet is configured to spray the water onto the door body.

[0157] It should be understood that the first inlet of the first delivery passage may receive the detergent solution or water based on requirements of the clothes treatment apparatus 1, and when the first inlet of the first delivery passage receives the detergent solution, the detergent solution is delivered into the clothes treatment cavity 1041 through the first outlet, and when the first inlet of the first delivery passage receives water, the water is delivered into the clothes treatment cavity 1041 through the first outlet.

[0158] Furthermore, the detergent solution received by the first inlet is a fluid obtained by mixing the detergent with water, and at this time, the detergent in the detergent solution has a uniform and stable concentration. Compared to the related art where the detergent and water are delivered into the clothes treatment cavity 1041 directly and then mixed, the detergent solution of the disclosure may be delivered into the clothes treatment cavity 1041 through the first outlet such that the detergent has a more uniform concentration.

[0159] When the clothes are washed by the clothes treatment apparatus 1, the door body is flushed by using the second delivery passage, and the detergent solution is delivered into the clothes treatment cavity 1041 by using the first delivery passage, thereby reducing a problem of the detergent becoming less effective due to uneven mixing of the detergent and water in the clothes treatment cavity 1041, such that a washing effect of the clothes may be improved. Furthermore, not only the detergent solution may be delivered into the clothes treatment cavity 1041 through the first delivery passage, but also water may be delivered into the clothes treatment cavity 1041 through the first delivery passage, which achieves that two fluids are delivered through one delivery assembly, therefore structures of the clothes treatment apparatus 1 may be simplified, such that cost of manufacturing the clothes treatment apparatus 1 may be reduced.

[0160] Furthermore, the second outlet of the second delivery passage is configured to spray water toward the door body, and it may achieve that the door body is flushed by using the sprayed water, reducing residuals of the detergent on the door body, thereby reducing an adverse effect of residuals of the detergent on the door body to rinsing in a process of rinsing the clothes with water.

[0161] It should be pointed out that the door body is usually in a transparent structure, and a corresponding condition in the clothes treatment cavity 1041 may be observed by the user through the door body, thereby improving the user's use experience; furthermore, the second outlet is arranged to spray water toward the door body, and it may achieve that the door body is flushed by using the sprayed water, reducing residuals of the detergent on the door body, improving permeability of the door body, and improving convenience of observation by the user.

When it needs to deliver water into the clothes treatment cavity 1041, water enters the mixing cavity 71 through the first liquid inlet 711 (the detergent does not enter the mixing cavity 71 through the second liquid inlet 712), and water enters the clothes treatment cavity 1041 through the mixing cavity 71, the first liquid discharge port 713 and the first delivery passage, thereby achieving that the clothes are rinsed.

[0164] It should be understood that the detergent and water are mixed in the mixing cavity 71, therefore uniformity of the detergent in the detergent solution may be improved, such that the treatment effect of the clothes may be improved effectively.

When the mixer 70 is used, water enters the mixing cavity 71 through the first liquid inlet 711, and the detergent enters the mixing cavity 71 through the second liquid inlet 712. Since the second liquid inlet 712 and the first liquid inlet 711 are arranged close to each other, the detergent and water entering the mixing cavity 71 may be quickly mixed to form a detergent solution, the formed detergent solution is mixed again in a process of flowing from the mixing cavity 71 to the liquid outlet, such that uniformity of mixing the detergent with water is improved, and thus uniformity of the detergent solution entering the clothes treatment cavity 1041 through the liquid outlet and the first delivery passage is improved, then the washing effect of the clothes is further improved.

[0179] Furthermore, when the second liquid inlet 712 is arranged tangentially to a circulation cross section of the mixing cavity 71, when the detergent in the detergent box assembly 20 is injected into the mixing cavity 71 through the second liquid inlet 712, the detergent has a component velocity along a circumferential direction of the mixing cavity 71, such that the detergent has multiple flowing directions in the mixing cavity 71, which increases a chance of the detergent coming into contact with water, such that uniformity of mixing the detergent with water is further improved. Furthermore, an entry direction of the second liquid inlet 712 is arranged at an acute angle with the axial direction of the mixing cavity 71, and the second liquid inlet 712 is inclined toward a side of the first liquid inlet 711, such that the detergent entering the mixing cavity 71 through the second liquid inlet 712 has a component velocity from the first end to the second end of the mixing cavity 71 simultaneously.

[0180] Furthermore, when the first liquid inlet 711 is arranged tangentially to the circulation cross section of the mixing cavity 71 (their tangent directions are opposite), when the detergent in the detergent box assembly 20 is injected into the mixing cavity 71 through the second liquid inlet 712 and water in the water supply pipeline is injected into the mixing cavity 71 through the first liquid inlet 711, each of the detergent and water has a component velocity along the circumferential direction of the mixing cavity 71, such that each of the detergent and water has multiple flowing directions in the mixing cavity 71, which further increases a chance of the detergent coming into contact with water, such that uniformity of mixing the detergent with water is further improved. Furthermore, an entry direction of the first liquid inlet 711 is arranged at an acute angle with the axial direction of the mixing cavity 71, and the first liquid inlet 711 is inclined toward a side away from the second liquid inlet 712, such that water entering the mixing cavity 71 through the first liquid inlet 711 has a component velocity from the first end to the second end of the mixing cavity 71 simultaneously.

[0181] Furthermore, when the second liquid inlet 712 and the first liquid inlet 711 are arranged tangentially to the circulation cross section of the mixing cavity 71 respectively, when water in the water supply pipeline is injected into the mixing cavity 71 through the first liquid inlet 711, the water has a component velocity along the circumferential direction of the mixing cavity 71, such that the water has multiple flowing directions in the mixing cavity 71, which increases a chance of the water coming into contact with the detergent, such that uniformity of mixing the detergent with water is further improved. Furthermore, the entry direction of the second liquid inlet 712 is arranged at an acute angle with the axial direction of the mixing cavity 71, and the second liquid inlet 712 is inclined toward a side of the first liquid inlet 711, such that the detergent entering the mixing cavity 71 through the second liquid inlet 712 has a component velocity from the first end to the second end of the mixing cavity 71 simultaneously. The entry direction of the first liquid inlet 711 is arranged at an acute angle with the axial direction of the mixing cavity 71, and the first liquid inlet 711 is inclined toward a side away from the second liquid inlet 712, such that water entering the mixing cavity 71 through the first liquid inlet 711 has a component velocity from the first end to the second end of the mixing cavity 71 simultaneously.

[0182] Furthermore, the mixing cavity 71 may be in a truncated cone structure, the first end and the second end are two ends of the mixing cavity 71 along the axial direction thereof, a circulation cross section of the second end is less than a circulation cross section of the first end, and the liquid outlet is located at the second end and is coaxially arranged with the mixing cavity 71.

[0183] Specifically, when the mixer 70 is used, the detergent in the detergent box assembly 20 is injected into the mixing cavity 71 through the second liquid inlet 712, water in the water supply pipeline is injected into the mixing cavity 71 through the first liquid inlet 711 only, the detergent and water entering the mixing cavity 71 flow from the first end to the second end and are mixed in their flowing processes, to form a detergent solution. The liquid outlet is arranged at the second end, and the second end is set to have a circulation area less than a circulation area of the first end, such that the detergent solution is in a state where it is compressed in a process of flowing to the second end, therefore uniformity of mixing the detergent may be further improved, such that uniformity of the detergent solution is further improved.

[0184] It should be understood that the mixing cavity 71 is in a truncated cone structure, and the circulation cross section of the second end is less than the circulation cross section of the first end, therefore the detergent solution is squeezed by using structural contraction, such that a flow rate of the detergent solution may be increased, thereby improving output efficiency of the detergent solution.

[0185] Furthermore, the mixing cavity 71 may also be in a cone structure, the first end and the second end are two ends of the mixing cavity 71 along the axial direction thereof, a circulation cross section of the second end is less than a circulation cross section of the first end, and the liquid outlet is located at the second end and is coaxially arranged with the mixing cavity 71.

The first liquid discharge port 713 is arranged at the second end, and the second end is set to have a circulation area less than a circulation area of the first end, such that the detergent solution is in a state where it is compressed in a process of flowing to the second end, therefore uniformity of mixing the detergent may be further improved, such that uniformity of the detergent solution is further improved.

[0187] It should be understood that the mixing cavity 71 is in a cone structure, and the circulation cross section of the second end is less than the circulation cross section of the first end, therefore the detergent solution is squeezed by using structural contraction, such that the flow rate of the detergent solution may be increased, thereby improving output efficiency of the detergent solution.

[0188] Furthermore, the mixing cavity 71 may also be in a column structure, the first end and the second end are two ends of the mixing cavity 71 along the axial direction thereof, the liquid outlet is located at the second end and is coaxially arranged with the mixing cavity 71, an area of the mixing cavity 71 at the second end is larger than an area of the liquid outlet, a deflector structure is arranged between the second end and a side wall of the mixing cavity 71, and the deflector structure is configured to guide the mixed solution in the mixing cavity 71 to the liquid outlet.

[0189] Specifically, the deflector structure is formed on an inner wall of the mixing cavity 71 and is a conical surface, the mixing cavity 71 is in a shape of a truncated cone structure between the deflector structure and the second end, the mixing cavity 71 is in a shape of a column structure between the deflector structure and the first end. The mixing cavity 71 with the deflector structure is in a combination structure formed by a truncated cone structure + a column structure, the structure of the mixing cavity 71 may have a volume greater than those of the mixing cavity 71 in a cone structure and the mixing cavity 71 in a truncated cone structure, thereby improving ability of mixing the detergent, and further meeting requirements of the clothes treatment cavity 1041 on the detergent solution effectively.

[0190] It should be pointed out that along the axial direction of the mixing cavity 71, a size of the column structure is greater than a size of the truncated cone structure, therefore the volume of the mixing cavity 71 may be increased.

[0228] Descriptions will be made below by an example that the first nozzle 10 is an atomizing nozzle.

[0229] In the related art, the detergent solution is sprayed into the clothes treatment cavity 1041 through a conventional nozzle, the detergent solution sprayed from the conventional nozzle is in a form of jet and has a small coverage area. In the disclosure, the first nozzle 10 is configured as an atomizing nozzle, then in a process of spraying the detergent solution into the clothes treatment cavity 1041 by the atomizing nozzle, the atomizing nozzle may spray the detergent solution in a form of mist (small droplets or small bubbles, etc.). Compared to the detergent solution in a form of jet, the detergent solution in a form of mist may increase a coverage area in the clothes treatment cavity 1041, such that an area where the clothes are wetted is increased, thereby increasing the contact area between the detergent solution and the clothes, and further improving the washing effect of the detergent on the clothes.

[0230] In some implementations of the disclosure, as shown in FIG. 18 to FIG. 21, a liquid inlet 16, a liquid outlet 17 and a pipe cavity 12 are arranged on the first nozzle 10 respectively, the pipe cavity 12 is communicated with the liquid inlet 16 and the liquid outlet 17 respectively, the first liquid discharge port 713 of the mixing cavity 71 is communicated with the liquid inlet 16, the liquid outlet 17 forms the first outlet of the first delivery passage and is arranged to face toward the clothes treatment cavity 1041.

[0232] Furthermore, there may be one, two, three, four, five liquid outlets 17, etc. When multiple first outlets are provided, an amount of spraying fluid may be increased, and sufficiency of contact between the clothes and the fluid may be further improved, such that the treatment effect of the clothes is further improved. When there are multiple (two or more) liquid outlets 17, spraying directions of all the multiple liquid outlets 17 may be the same, or spraying directions of a portion of the multiple liquid outlets 17 may be the same (sprayed regions may be increased), or spraying directions of all the multiple liquid outlets 17 are completely different (sprayed regions may be increased). Furthermore, when there are multiple (two or more) liquid outlets 17, along a circumferential direction of the first nozzle 10, all the multiple liquid outlets 17 may be overlapped, or a portion of the multiple liquid outlets 17 may be overlapped (sprayed regions may be increased), or all the multiple liquid outlets 17 may be staggered (sprayed regions may be increased).

[0233] In some implementations of the disclosure, a flow disturbance structure 18 is arranged in the pipe cavity 12 of the first nozzle 10.

[0234] Specifically, the flow disturbance structure 18 is arranged in the pipe cavity 12 of the first nozzle 10, and when the fluid (the detergent solution or water) output from the mixer 70 enters the pipe cavity 12 of the first nozzle 10, the fluid is discharged from the liquid inlet 16 to the liquid outlet 17, and when the fluid passes through the flow disturbance structure 18, the flow disturbance structure 18 disturbs flow of the fluid, such that the fluid has a component velocity along the circumferential direction of the pipe cavity 12, and the fluid also has a component velocity along the axial direction of the pipe cavity 12 at this time. The fluid having a component velocity along each of the circumferential direction and axial direction of the pipe cavity 12 may form a mist structure when it is sprayed through the liquid outlet 17 of the first nozzle 10, therefore the coverage area of the nozzle in the clothes treatment cavity 1041 may be increased, such that the clothes may be fully in contact with the fluid, thereby improving the treatment effect of the clothes.

[0235] It should be understood that when there is no flow disturbance structure 18 in the pipe cavity 12, the fluid has only a velocity along the axial direction of the pipe cavity 12, the fluid may form a jet when it is sprayed through the liquid outlet 17 at this time, the jet has a small coverage area in the clothes treatment cavity 1041, and the clothes cannot be fully in contact with the fluid, which may cause a poor treatment effect of the clothes.

[0236] It should be pointed out that the flow disturbance structure 18 is arranged in the pipe cavity 12 of the first nozzle 10, the flow disturbance structure 18 may be integrally formed with the first nozzle 10 or may be assembled in the pipe cavity 12 of the first nozzle 10.

The liquid inlet 16 is communicated with the first pipe cavity section 121, the liquid outlet 17 is communicated with the second pipe cavity section 122, and the flow disturbance structure 18 is arranged in the first pipe cavity section 121. At least a portion of a circulation cross section of the first pipe cavity section 121 is in a converging structure along a direction from the first pipe cavity section 121 to the second pipe cavity section 122.

[0239] Specifically, when the fluid of the mixer 70 enters the pipe cavity 12 through the liquid inlet 16 of the first nozzle 10, the fluid enters the first pipe cavity section 121 of the pipe cavity 12 first, circulates along the first pipe cavity section 121 and toward the second pipe cavity section 122, and is disturbed by the flow disturbance structure 18 in its flowing process, such that the fluid has a component velocity along each of the circumferential direction and axial direction of the pipe cavity 12, the fluid passes through the second pipe cavity section 122, and the fluid is sprayed through the liquid outlet 17 in a form of mist, thereby increasing the coverage area of the fluid in the clothes treatment cavity 1041. Since at least a portion of the circulation cross section of the first pipe cavity section 121 is in a converging structure along the direction from the first pipe cavity section 121 to the second pipe cavity section 122, the fluid is compressed by the converging structure when the fluid passes through the converging structure, such that velocity of the fluid is increased, therefore the fluid flowing out through the second pipe cavity section 122 and sprayed into the clothes treatment cavity 1041 through the liquid outlet 17 has a high spraying velocity, further increasing an area sprayed by the fluid in the clothes treatment cavity 1041.

[0240] It should be pointed out that the flow disturbance structure 18 is arranged in the first pipe cavity section 121, and the flow disturbance structure 18 is located between two ends of the first pipe cavity section 121 (here one of the two ends is an inlet of the first nozzle 10, and another one of the two ends is a communication position between the first pipe cavity section 121 and the second pipe cavity section 122).
