[0034] The present application proposes a laundry treatment device, which may be a washing machine, an all-in-one washing and drying machine, or other laundry treatment devices having a washing function. For convenience of description, the present application only takes the laundry treatment device as a drum-type all-in-one washing and drying machine as an example.

[0035] As shown in FIGS. 1 and 2, in some embodiments of the present application, the laundry treatment device 1 includes a box body 102 which forms an appearance structure of the laundry treatment device 1, and an installation chamber in which an laundry treatment drum 104 and various components are installed is arranged inside the box body 102. The laundry treatment drum 104 is arranged in the installation chamber, and the laundry treatment drum 104 is arranged in the horizontal direction or at an angle with respect to the horizontal direction. A laundry treatment chamber 1041 is arranged inside the laundry treatment drum 104, and is configured to hold laundries for washing the laundries. A delivery port communicating with the laundry treatment chamber 1041 is arranged at a front end of the laundry treatment drum 104, and a door body 103 is connected to a front end of the box body 102. The delivery port can be opened or closed by operating the door body 103, so that the laundries can be delivered into the laundry treatment chamber 1041 through the delivery port. Specifically, the door body 103 is rotatably connected to the box body 102.

[0036] As shown in FIGS. 2 and 3, in some embodiments of the present application, a detergent delivery apparatus 101 is arranged inside the box body 102, and the detergent delivery apparatus 101 is configured to deliver detergent to the laundry treatment chamber 1041, to enhance the washing effect of the laundries. The detergent delivery apparatus 101 can be configured to deliver liquid detergent and / or solid detergent. The liquid detergent may include washing agents, softeners, bactericides, care agents and other commonly used formulations, and the solid detergent may include powder, laundry detergent, gel, bead, and the like.

[0037] As shown in FIGS. 2 and 3, in some embodiments of the present application, the detergent delivery apparatus 101 includes a detergent cartridge assembly 20 and a first pipeline component. The detergent cartridge assembly 20 includes a cartridge body 21, and a detergent chamber configured to hold the detergent is arranged inside the cartridge body 21. One end of the first pipeline component communicates with the detergent chamber, and another end of the first pipeline component is configured to deliver the detergent toward the interior of the laundry treatment chamber 1041.

[0038] The detergent cartridge assembly 20 and / or the first pipeline component may also be provided with a gas intake structure, and the gas intake structure is configured to introduce gas outside the detergent delivery apparatus into the detergent delivery apparatus, thereby increasing the gas content of the detergent in the detergent delivery apparatus, further increasing the number of bubbles formed by the detergent delivered, increasing the contact area between the detergent and the laundries, improving the utilization rate of the detergent, and enhancing the washing effect of the laundries.

[0039] In addition, by forming the bubbles by the detergent delivered, a large number of bubbles can produce more foam under impact, the cleaning ingredients are relatively dispersed, and the foam can cover more areas of the laundries, thus increasing the contact area between the detergent and the laundries and improving the washing effect. Moreover, the laundries can be wet by introducing a small amount of washing water into the laundry treatment chamber 1041, which can effectively reduce the use of washing water compared with the conventional washing method of introducing a large amount of washing water into the laundry treatment chamber 1041.

[0040] As shown in FIGS. 2 and 3, in some embodiments of the present application, the first pipeline component 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 a gas intake structure.

[0041] As shown in FIGS. 4 to 6, in some embodiments of the present application, the first nozzle 10 is provided with a gas intake structure communicating with the outside. The first nozzle 10 includes a pipe body 11 and a pipe cavity 12 arranged inside the pipe body 11, the gas intake structure includes a suction hole 13 arranged on a side wall of the pipe body 11, and the suction hole 13 communicates the interior and the exterior of the pipe body 11. Gas outside the pipe body 11 can enter into the pipe cavity 12 through the suction hole 13, thereby increasing the gas content in the pipe cavity 12, and thus increasing the gas content of the detergent and / or washing water in the pipe cavity 12.

[0042] As shown in FIGS. 4 to 6, in some embodiments of the present application, the pipe cavity 12 includes a first pipe cavity section 121, a second pipe cavity section 122, and a third pipe cavity section 123 which sequentially communicate with each other. The flow area of the first pipe cavity section 121 gradually decreases in a direction from the first pipe cavity section 121 to the second pipe cavity section 122, and the flow area of the third pipe cavity section 123 gradually increases in a direction from the second pipe cavity section 122 to the third pipe cavity section 123. The suction hole 13 arranged on the side wall of the pipe body 11, and the suction hole 13 communicates the interior and the exterior of the pipe body 11.

[0043] By arranging the first pipe cavity section 121, the second pipe cavity section 122, and the third pipe cavity section 123 according to the structures described above, the interior of the pipe cavity 12 forms a structure similar to a venturi pipe, and the venturi effect can be generated accordingly. The venturi effect refers to the fact that when fluid passes through a narrow part of a pipe, it will cause the fluid velocity at this part to increase and the static pressure at this part to decrease. Since the second pipe cavity section 122 is narrower than the first pipe cavity section 121 and the third pipe cavity section 123, by communicating the suction hole 13 with the second pipe cavity section 122, when the fluid flows in the pipe cavity 12, for example, when the detergent and / or washing water flows in the pipe cavity 12, the gas outside the pipe body 11 can enter the pipe cavity 12 through the suction hole 13 under the action of venturi effect in the pipe cavity 12. In this way, the gas content of the detergent and / or washing water in the pipe cavity 12 is increased, the number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10 is in turn increased, and the washing effect of the laundries is improved.

[0044] As shown in FIGS. 4 to 6, in some embodiments of the present application, a communication cavity 14 is further arranged on the side wall of the pipe body 11, and the suction hole 13 communicates with the second pipe cavity section 122 through the communication cavity 14.

[0045] The communication cavity 14 is provided to communicate the suction hole 13 and the second pipe cavity section 122, and by arranging the flow area and the flow path of the communication cavity 14, the fluid flowing through the second pipe cavity section 122 can be prevented from flowing to the exterior of the pipe body 11 through the suction hole 13.

[0046] Specifically, in some embodiments of the present application, the communication cavity 14 includes a first communication portion 141 and a second communication portion 142. The second pipe cavity section 122, the first communication portion 141, the second communication portion 142, and the suction hole 13 communicate with each other sequentially. In an axial direction of the second pipe cavity section 122, the dimension L1 of the first communication portion 141 is less than the dimension L2 of the second communication portion 142, the dimension L3 of the suction hole 13, and the dimension L4 of the second pipe cavity section 122.

[0047] That is, an end of the communication cavity 14 close to the second pipe cavity section 122 has a minimum opening dimension, thereby preventing the fluid in the second pipe cavity section 122 from flowing to the exterior of the pipe body 11 through the communication cavity 14 and the suction hole 13 in sequence. In addition, since the dimension L1 of the first communication portion 141 is less than the dimension L2 of the second communication portion 142, a bent structure is formed, and in some embodiments, the fluid in the second pipe cavity section 122 is prevented from flowing to the exterior of the pipe body 11 through the communication cavity 14 and the suction hole 13 in sequence.

[0048] As shown in FIGS. 4 to 6, in some embodiments of the present application, the opening area of the suction hole 13 may be consistent with the flow area of the second pipe cavity section 122, thereby increasing the amount of intake gas in the pipe cavity 12.

[0049] As shown in FIGS. 4 to 6, in some embodiments of the present application, in the axial direction of the second pipe cavity section 122, each of the projection of the first communication portion 141 and the projection of the second communication portion 142 is partially annular. The value range of a central angle a corresponding to the projection of the first communication portion 141 is 0° < a ≤ 180°, and / or the value range of a central angle b corresponding to the projection of the second communication portion 142 is 0° < b ≤ 180°.

[0050] That is, the first communication portion 141 may be a sector-shaped structure or a semi-circular annular structure, and / or the second communication portion 142 may be a sector-shaped structure or a semi-circular annular structure, thereby increasing the flow area of the communication cavity 14 and further increasing the amount of intake gas in the pipe cavity 12.

[0051] As shown in FIGS. 4 to 6, in some embodiments of the present application, the value of the central angle a corresponding to the projection of the first communication portion 141 is 180°, the value of the central angle b corresponding to the projection of the second communication portion 142 is 180°, the second pipe cavity section 122 is a circular pipe cavity section, the diameter dimension R of the second pipe cavity section 122 is consistent with the dimension L4 of the second pipe cavity section 122 in the axial direction, the second pipe cavity section 122 has a flow area S1, and the first communication portion 141 has a minimum flow area S2, in which S1 is greater than S2.

[0052] Specifically, each of the first communication portion 141 and the second communication portion 142 is a semicircular structure. By setting S1 to be greater than S2, the flow area of the first communication portion 141 is less than the flow area of the second pipe cavity section 122, which reduces the occurrence of a phenomenon in which the fluid in the second pipe cavity section 122 flows to the exterior of the pipe body 11 through the first communication portion 141 and the suction hole 13.

[0053] Specifically, the ratio of S1: S2 is 4: 1. Herein, the diameter dimension of the second pipe cavity section 122 is R, the flow area of the second pipe cavity section 122 is S1 = πR2, the arc length of the first communication portion 141 is π R, the dimension of the first communication portion 141 in the axial direction is L1, and the flow area of the first communication portion 141 is S2 = πRL1. Since the ratio of S1: S2 is 4: 1, the ratio of R to L1 is 4: 1. Since the dimension L4 of the second pipe cavity section 122 in the axial direction and the diameter dimension of the second pipe cavity section 122 are identical and equal to R, L4 is equal to four times L1.

[0054] As shown in FIGS. 4 to 6, in some embodiments of the present application, the suction hole 13 is a circular hole, and the value range of the diameter dimension L3 of the suction hole 13 is 2 mm ≤ L3 ≤ 3.6 mm.

[0055] In some embodiments of the present application, since the opening area of the suction hole 13 is consistent with the flow 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. In some embodiments of the present application, since the dimension L4 of the second pipe cavity section 122 in the axial direction is equal to the diameter dimension R of the second pipe cavity section 122, the value of the dimension L4 is 2 mm ≤ L4 ≤ 3.6 mm.

[0056] As shown in FIGS. 4 to 6, in some embodiments of the present application, a liquid outlet 17 communicating with the pipe cavity 12 is arranged at an end of the third pipe cavity section 123 away from the second pipe cavity section 122, and an axis of the suction hole 13 and an axis of the liquid outlet 17 are arranged at an angle of 90° to 180°.

[0057] That is, in a circumferential direction of the second pipe cavity section 122, the liquid outlet 17 and the suction hole 13 are arranged at an angle of 90° to 180°, thereby reducing the occurrence of the phenomenon that the fluid flows into the suction hole 13 under the action of the gas flow after flowing out through the liquid outlet 17. Specifically, the angle between the liquid outlet 17 and the suction hole 13 may be any value between 90° and 120°, between 120° and 150°, and between 150° and 180°. When the liquid outlet 17 and the suction hole 13 are arranged at an angle of 180°, it is possible to minimize the occurrence of the phenomenon that the fluid flows into the suction hole 13 under the action of the gas flow after flowing out through the liquid outlet 17.

[0058] As shown in FIGS. 2 to 6, in some embodiments of the present application, a fixing portion 15 is arranged on an outer surface of the pipe body 11 and protrudes from the outer surface, and the liquid outlet 17 and the suction hole 13 are jointly arranged at the same side of the fixing portion 15 in the axial direction of the second pipe cavity section 122.

[0059] Specifically, the fixing portion 15 is configured to fix the overall mounting position of the first nozzle 10. Since the laundry treatment drum 104 rotates during the washing of the laundries, the first nozzle 10 is not suitable for passing directly through the laundry treatment drum 104 and being inserted into the laundry treatment chamber 1041. In some embodiments of the present application, the first nozzle 10 may be arranged on a door seal 105 at the front end of the laundry treatment drum 104, and the front end of the laundry treatment drum 104 is an end thereof facing toward the door body 103. The fixing portion 15 is arranged inside the door seal 105 and snap-fitted with the door seal 105, an end of the first nozzle 10 provided with the liquid outlet 17 passes through the door seal 105 and is arranged inside the laundry treatment chamber 1041, the first nozzle 10 delivers the detergent toward the laundry treatment chamber 1041 by spraying, and another end of the first nozzle 10 is arranged outside the door seal 105 and is configured to communicate with the first liquid supply pipe 30. The liquid outlet 17 and the suction hole 13 are jointly arranged on the same side of the fixing portion 15 facing toward the laundry treatment chamber 1041, that is, the liquid outlet 17 and the suction hole 13 are jointly arranged on the inner side where the door seal 105 communicates with the laundry treatment chamber 1041. In this way, even if a fluid leakage occurs at the suction hole 13, the leaked fluid will not fall on other electrical components outside the laundry treatment drum 104, thereby reducing the occurrence of safety accidents.

[0060] In some embodiments of the present application, a maximum spacing dimension between the suction hole 13 and the fixing portion 15 is less than a minimum spacing dimension between the liquid outlet 17 and the fixing portion 15.

[0061] When the first nozzle 10 is mounted inside the laundry treatment device 1, the first nozzle 10 is arranged in a substantially vertical direction or at an angle with respect to the vertical direction. In the vertical direction, the liquid outlet 17 is arranged at a bottom end of the first nozzle 10, the suction hole 13 is arranged above the liquid outlet 17, the fixing portion 15 is arranged above the suction hole 13, and a maximum spacing dimension between the suction hole 13 and the fixing portion 15 is less than a minimum spacing dimension between the liquid outlet 17 and the fixing portion 15. That is, any location of the suction hole 13 is not located below the liquid outlet 17, thereby reducing the phenomenon that fluid flows into the suction hole 13 after flowing out through the liquid outlet 17.

[0062] As shown in FIGS. 4 to 6, in some embodiments of the present application, 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 communicating with the pipe cavity 12.

[0063] Specifically, the liquid inlet 16 is arranged at the top of the fourth pipe cavity section 124, and the first nozzle 10 communicates with the first liquid supply pipe 30 through the liquid inlet 16, to transport the fluid to the interior of the pipe cavity 12. The fourth pipe cavity section 124 is generally a straight pipe cavity section, to facilitate the transportation of the fluid or facilitate the arrangement of other structures inside the fourth pipe cavity section 124.

[0064] As shown in FIGS. 4 to 6, in some embodiments of the present application, a flow disturbing structure 18 is further arranged in the pipe cavity 12, so that the fluid flowing through the flow disturbing structure 18 in the pipe cavity 12 has a component velocity in the circumferential direction of the pipe cavity 12.

[0065] By arranging the flow disturbing structure 18 in the pipe cavity 12 of the first nozzle 10, the fluid flowing through the flow disturbing structure 18 in the pipe cavity 12 has a component velocity in 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 in the circumferential direction of the pipe cavity 12 can increase the spray angle of the fluid, thereby improving the spray area of the first nozzle 10, improving the contact area between the detergent and / or washing water and the laundries, increasing the utilization rate of the detergent and / or washing water, and improving the washing effect of the laundries.

[0066] Specifically, the flow disturbing structure 18 may be arranged in the fourth pipe cavity section 124. During the flow of the fluid in the pipe cavity 12, firstly the fluid is formed with a component velocity in the circumferential direction of the pipe cavity 12 through the action of the flow disturbing structure 18, and then the gas content in the fluid is increased through the gas supplement action of the suction hole 13. After the fluid is sprayed from the liquid outlet 17, the spray angle can be diffused in the circumferential direction of the pipe cavity 12, and a large number of bubble structures can be formed at the same time, to effectively improve the contact area between the medium and the laundries, such as the contact area between the detergent and / or the washing water and the laundries, which increases the utilization rate of the detergent and / or the washing water, and improves the washing effect of the laundries.

[0067] As shown in FIGS. 4 to 6, in some embodiments of the present application, the flow disturbing structure 18 includes at least one flow disturbing plate 181, and a plate surface of the flow disturbing plate 181 is arranged at an angle with the axial direction of the pipe cavity 12. Since the plate surface of the flow disturbing plate 181 is arranged at an angle with the axial direction of the pipe cavity 12, when the fluid flows through the flow disturbing plate 181, the fluid passing through the flow disturbing plate 181 can flow in the direction of the plate surface of the flow disturbing plate 181, so that the flow direction of the fluid is arranged at an angle with the axial direction of the pipe cavity 12, and in turn the fluid has a component velocity in the circumferential direction of the pipe cavity 12.

[0068] As shown in FIGS. 4 to 6, in some embodiments of the present application, the flow disturbing structure 18 includes a plurality of flow disturbing plates 181, the plurality of flow disturbing plates 181 are spaced apart from each other along the circumferential direction of the pipe cavity 12, and the angle between the plate surface of any one of the flow disturbing plates 181 and the axial direction of the pipe cavity 12 is the same as the angle between the plate surface of any other of the flow disturbing plates 181 and the axial direction of the pipe cavity 12.

[0069] By simultaneously providing the plurality of flow disturbing plates 181, the flow disturbing effect of the flow disturbing structure 18 can be improved, thereby improving the diffusion of the spray angle of the detergent and / or the washing water in the circumferential direction of the pipe cavity 12 after the detergent and / or the washing water are sprayed from the liquid outlet 17, increasing the contact area between the detergent and / or the washing water and the laundries, increasing the utilization rate of the detergent and / or the washing water, and improving the washing effect of the laundries.

[0070] As shown in FIGS. 4 to 6, in some embodiments of the present application, the flow disturbing structure 18 further includes a connecting ring 182, the connecting ring 182 is provided with a first through hole 183 in the axial direction of the pipe cavity 12, and an end of each of the plurality of flow disturbing plates 181 is connected to an outer peripheral surface of the connecting ring 182.

[0071] Specifically, an end of each of the plurality of flow disturbing plates 181 is connected to the connecting ring 182, and another end of each of the plurality of flow disturbing plates 181 is connected to an inner wall of the pipe cavity 12. The plurality of flow disturbing plates 181 are spaced apart from each other in the circumferential direction of the connecting ring 182 by fixing the plurality of flow disturbing plates 181 through the connecting ring 182 at the same time, and the connecting ring 182 is provided with the first through hole 183 in the axial direction, so that the medium at the center position of the pipe cavity 12 flows through the connecting ring 182 through the first through hole 183, and the medium at a circumferential edge of the pipe cavity 12 has a component velocity in the circumferential direction of the pipe cavity 12 under the flow disturbing action of the plurality of flow disturbing plates 181.

[0072] In some embodiments of the present application, the structure of the connecting ring 182 may be cancelled. An end of each of the plurality of flow disturbing plates 181 may be connected to the inner wall surface of the pipe cavity 12, and another end of each of the plurality of flow disturbing plates 181 may be suspended. In this way, the plurality of flow disturbing plates 181 may be spaced apart from each other in the circumferential direction of the pipe cavity 12.

[0073] As shown in FIG. 7, in some embodiments of the present application, there are two flow disturbing plates 181, the two flow disturbing plates 181 are spaced apart from each other in the circumferential direction of the pipe cavity 12, and the two flow disturbing plates 181 are misaligned with each other in the axial direction of the pipe cavity 12.

[0074] Specifically, an end of each of the two flow disturbing plates 181 is connected to the inner wall surface of the pipe cavity 12, and another end of each of the two flow disturbing plates 181 is arranged spaced apart from the inner wall surface of the pipe cavity 12. The two flow disturbing plates 181 are arranged opposite to each other and spaced apart from each other by 180°, and one of the two flow disturbing plates 181 is at least partially arranged above another one of the two flow disturbing plates 181. After the fluid flows into the pipe cavity 12 through the liquid inlet 16, the fluid first collides with the flow disturbing plate 181 located above, thereby forming a component velocity in the circumferential direction of the pipe cavity 12. Then, during the falling process of the fluid, it collides with the flow disturbing plate 181 located below, to increase the component velocity of the fluid in the circumferential direction of the pipe cavity 12.

[0075] In some embodiments of the present application, in order to increase the probability that the fluid sequentially collides with the two flow disturbing plates 181 in the process of flowing through the pipe cavity 12, the dimension of each of the two flow disturbing plates 181 in a radial direction of the pipe cavity 12 exceeds the radial dimension of the pipe cavity 12, that is, the two flow disturbing plates 181 are partially structurally overlapped with each other in the axial direction of the pipe cavity 12.

[0076] As shown in FIG. 8, in some embodiments of the present application, the flow disturbing structure 18 is connected to the inner wall surface of the pipe cavity 12, the flow disturbing structure 18 is provided with at least one flow disturbing channel 185, and an axial direction of the flow disturbing channel 185 is arranged at an angle with the axial direction of the pipe cavity 12.

[0077] Specifically, one or more flow disturbing channels 185 may be arranged in the pipe cavity 12 at the same time, and the axial direction of each of the flow disturbing channels 185 is arranged at an angle with the axial direction of the pipe cavity 12, so that the fluid can form a component velocity in the circumferential direction of the pipe cavity 12 when flowing through the flow disturbing channels 185 during the process of flowing through the pipe cavity 12.

[0078] The flow disturbing structure 18 may include a mounting block 184, an outer wall surface of the mounting block 184 is arranged in close contact with the inner wall surface of the pipe cavity 12, at least two flow disturbing channels 185 are arranged in the mounting block 184, and the at least two flow disturbing channels 185 intersect with each other.

[0079] The outer wall surface of the mounting block 184 is arranged in close contact with the inner wall surface of the pipe cavity 12, so that there is no space for the fluid to flow between the mounting block 184 and the pipe cavity 12. In this way, the fluid in the pipe cavity 12 can only flow out through the flow disturbing channel 185, and thus most or all of the fluid in the pipe cavity 12 has a component velocity in the circumferential direction of the pipe cavity 12. The at least two flow disturbing channels 185 intersect with each other, that is, the fluid flowing out through the flow disturbing channels 185 can flow out in different directions, thereby increasing the collision probability of the fluid flowing out from the flow disturbing channels 185, and increasing the component velocity of the fluid in the circumferential direction of the pipe cavity 12.

[0080] As shown in FIGS. 5 to 8, the communication cavity 14 in each of the embodiments described above includes a first communication portion 141 and a second communication portion 142, to reduce the phenomenon that the fluid in the pipe cavity 12 leaks through the suction hole 13. In some embodiments of the present application, the structure of the communication cavity 14 may also be simplified.

[0081] As shown in FIG. 9, in some embodiments of the present application, the suction hole 13 communicates with the second pipe cavity section 122 through the communication cavity 14. The communication cavity 14 may be a straight pipe cavity or a partial arc pipe cavity, thereby reducing the arrangement of the first communication portion 141 and the second communication portion 142. The suction hole 13 may be a round hole or a square hole, and the flow area of the suction hole 13 gradually decreases in the direction from the exterior to the interior of the pipe body 11, which can also reduce the phenomenon that the fluid in the pipe cavity 12 leaks through the suction hole 13.

[0082] As shown in FIG. 9, in some embodiments of the present application, an end of the first pipe cavity section 121 close to the second pipe cavity section 122 is inclined in a direction toward the liquid outlet 17, so that in the process of the fluid flowing through the first pipe cavity section 121 to the second pipe cavity section 122, the component velocity of the fluid flowing in the direction toward the liquid outlet 17 can be increased, thereby increasing the spray angle of the fluid and increasing the spray area of the first nozzle 10.

[0083] As shown in FIGS. 2 and 3, in some embodiments of the present application, the first liquid supply pipe 30 may also be provided with a gas intake structure. The gas intake structure includes a communication hole (not shown) provided on a side wall of the first liquid supply pipe 30 and communicating the interior and exterior of the first liquid supply pipe 30. The gas at the exterior of the first liquid supply pipe 30 can enter the interior of the first liquid supply pipe 30 through the communication hole, thereby increasing the gas content in the first liquid supply pipe 30, in turn increasing the gas content of the detergent and / or the washing water in the first liquid supply pipe 30, increasing the number of bubbles formed by the detergent and / or the washing water sprayed from the first nozzle 10, increasing the contact area between the detergent and / or the washing water and the laundries, and improving the washing effect of the laundries.

[0084] As shown in FIGS. 2 and 3, in some embodiments of the present application, the gas intake structure further includes a gas supply assembly (not shown in the drawings), and the gas supply assembly is provided at the exterior of the first liquid supply pipe 30 and communicates with the interior of the first liquid supply pipe 30 through the communication hole. Herein, the gas supply assembly may be a gas supplement pump configured to pump gas to the interior of the first liquid supply pipe 30, thereby increasing the gas content in the first liquid supply pipe 30, and thus increasing the gas content of the detergent and / or the wash water in the first liquid supply pipe 30.

[0085] As shown in FIGS. 2 to 9, in some embodiments of the present application, the first liquid supply pipe 30 includes a first liquid supply section (not shown in the drawings), a second liquid supply section (not shown in the drawings) and a third liquid supply section (not shown in the drawings) which are connected to each other and communicate with each other in sequence. The flow area of the first liquid supply section gradually decreases in a direction from the first liquid supply section to the second liquid supply section, and the flow area of the third liquid supply section gradually increases along a direction from the second liquid supply section to the third liquid supply section. The communication hole communicates with the second liquid supply section.

[0086] The connection structural form of the first liquid supply section, the second liquid supply section, and the third liquid supply section may be consistent with the connection structural form of the first pipe cavity section 121, the second pipe cavity section 122, and the third pipe cavity section 123 in any of the embodiments described above.

[0087] By arranging the first liquid supply section, the second liquid supply section, and the third liquid supply section according to the structures described above, the interior of the first liquid supply pipe forms a structure similar to a venturi pipe, and the venturi effect can be generated accordingly. Since the second liquid supply section is narrower than the first liquid supply section and the third liquid supply section, by communicating the communication hole with the second liquid supply section, when the fluid flows in the first liquid supply pipe 30, such as when the detergent and / or washing water flows in the first liquid supply pipe 30, the gas outside the first liquid supply pipe 30 can enter the first liquid supply pipe 30 through the communication hole under the action of venturi effect in the first liquid supply pipe 30. In this way, the gas content of the detergent and / or washing water in the first liquid supply pipe 30 is increased, the number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10 is in turn increased, and the washing effect of the laundries is improved.

[0088] As shown in FIGS. 2, 3 and 10, in some embodiments of the present application, the detergent delivery apparatus 101 further includes a mixer 40, the mixer 40 is arranged outside the detergent cartridge assembly 20, and a mixing chamber is formed inside the mixer 40.
