Description

[0001] This application is a divisional application of the invention patent application with the application date of September 20, 2023, application number 202311222482.0, and name “Nozzle, detergent dispensing device and clothing processing equipment”. Technical Field

[0002] The present application belongs to the technical field of clothing processing equipment, and specifically relates to a nozzle, a detergent dispensing device and clothing processing equipment. Background Art

[0003] Currently, when adding detergent and / or wash water to the washing tub, washing machines typically use an atomizing nozzle to spray the detergent and / or wash water in the form of bubbles to ensure sufficient contact between the detergent and / or wash water and the clothes. However, existing atomizing nozzles only create an atomized spray by modifying the nozzle's outlet structure, resulting in a limited spray area. This reduces the contact area between the detergent and / or wash water and the clothes, thereby affecting the washing effect. Summary of the Invention

[0062] The present application proposes a clothing processing device, which may be a washing machine, a washer-dryer, or other clothing processing device with a laundry function. For the convenience of description, the present application only uses the clothing processing device as a drum-type washer-dryer as an example for illustration.

[0063] Combine Figure 1 and Figure 2 As shown, in some embodiments of the present application, the clothing processing device 1 includes a housing 102, which forms the external structure of the clothing processing device 1 and is provided with an installation cavity therein, for installing a clothing processing drum 104 and various components. The clothing processing drum 104 is provided in the installation cavity, and the clothing processing drum 104 is arranged in a horizontal direction or at an angle to the horizontal direction. A clothing processing chamber 1041 is provided inside the clothing processing drum 104 for storing clothes and washing them. A loading port connected to the clothing processing chamber 1041 is provided at the front end of the clothing processing drum 104, and a door 103 is also connected to the front end of the housing 102. By operating the door 103, the loading port can be opened or closed, so that clothes can be loaded into the clothing processing chamber 1041 through the loading port. Specifically, the door 103 is rotatably connected to the housing 102.

[0064] Combine Figure 2 and Figure 3 As shown, in some embodiments of the present application, a detergent dispensing device 101 is further provided inside the housing 102. The detergent dispensing device 101 is used to dispense detergent into the clothing processing chamber 1041, thereby enhancing the washing effect on the clothes. The detergent dispensing device 101 can be used to dispense liquid detergent and / or solid detergent. Liquid detergents may include detergents, softeners, fungicides, care agents, and other commonly used preparations. Solid detergents may include washing powders, liquid laundry detergents, laundry gels, and laundry beads.

[0065] Combine Figure 2 and Figure 3 As shown, in some embodiments of the present application, the detergent dispensing device 101 includes a detergent box assembly 20 and a first pipe assembly, the detergent box assembly 20 includes a box body 21, the interior of the box body 21 is provided with a detergent cavity for storing detergent, one end of the first pipe assembly is connected to the detergent cavity, and the other end of the first pipe assembly is used to dispense detergent toward the interior of the clothing processing cavity 1041.

[0066] Among them, the detergent box assembly 20 and / or the first pipeline assembly may also be provided with an air intake structure, which is used to introduce gas outside the detergent dispensing device into the detergent dispensing device, thereby increasing the gas content of the detergent in the detergent dispensing device, and then increasing the number of bubbles formed by the dispensed detergent, increasing the contact area between the detergent and the clothes, improving the utilization rate of the detergent, and enhancing the washing effect of the clothes.

[0067] At the same time, by forming bubbles into the detergent, a large number of bubbles can produce more foam under impact, the cleaning ingredients are more dispersed, and the foam can cover more areas of the clothes, thereby increasing the contact area between the detergent and the clothes and improving the washing effect. A small amount of washing water can be passed into the clothing processing chamber 1041 to moisten the clothes. Compared with the conventional water washing method of passing a large amount of washing water into the clothing processing chamber 1041, the use of washing water can be effectively reduced.

[0068] Combine Figure 2 and Figure 3 As shown, in some embodiments of the present application, the first pipeline assembly includes a first liquid supply pipe 30 and a first nozzle 10, wherein the first liquid supply pipe 30 and / or the first nozzle 10 is provided with an air intake structure.

[0069] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the first nozzle 10 is provided with an air intake structure connected to the outside. The first nozzle 10 includes a tube body 11 and a tubular cavity 12 disposed within the tubular body 11. The air intake structure includes an air intake hole 13 disposed on the sidewall of the tubular body 11 and connecting the inside and outside of the tubular body 11. Gas outside the tubular body 11 can enter the tubular cavity 12 through the air intake hole 13, thereby increasing the gas content in the tubular cavity 12, and thereby increasing the gas content of the lotion and / or wash water in the tubular cavity 12.

[0070] Combine Figures 4 to 6As shown, in some embodiments of the present application, the tubular cavity 12 includes a first tubular cavity segment 121, a second tubular cavity segment 122 and a third tubular cavity segment 123 that are connected in sequence. Along the direction of the first tubular cavity segment 121 toward the second tubular cavity segment 122, the flow area of ​​the first tubular cavity segment 121 gradually decreases, and along the direction of the second tubular cavity segment 122 toward the third tubular cavity segment 123, the flow area of ​​the third tubular cavity segment 123 gradually increases. The suction hole 13 is provided on the side wall of the tube body 11 and connects the inside and outside of the tube body 11.

[0071] By arranging the first, second, and third lumen sections 121, 122, and 123 in the aforementioned configuration, the interior of lumen 12 forms a structure similar to a Venturi tube, thereby generating a Venturi effect. The Venturi effect refers to the increase in fluid velocity and decrease in static pressure at a narrow section of a pipe as fluid passes through it. Since the second tube cavity section 122 is narrower than the first tube cavity section 121 and the third tube cavity section 123, by connecting the air suction hole 13 with the second tube cavity section 122, when fluid flows in the tube cavity 12, such as when lotion and / or washing water flows in the tube cavity 12, under the action of the Venturi effect in the tube cavity 12, the external gas of the tube body 11 can enter the tube cavity 12 through the air suction hole 13, thereby increasing the gas content in the lotion and / or washing water in the tube cavity 12, and then increasing the number of bubbles formed by the lotion and / or washing water sprayed from the first nozzle 10, increasing the contact area between the lotion and / or washing water and the clothes, and improving the washing effect of the clothes.

[0072] Combine Figures 4 to 6 As shown, in some embodiments of the present application, a communication cavity 14 is further provided in the side wall of the tube body 11 , and the air suction hole 13 is connected to the second tube cavity section 122 through the communication cavity 14 .

[0073] The through hole is provided with a connecting cavity 14 connecting the air intake hole 13 and the second tube cavity section 122 . The flow area and flow path of the connecting cavity 14 can be set to prevent the fluid flowing through the second tube cavity section 122 from flowing out to the outside of the tube body 11 through the air intake hole 13 .

[0074] Specifically, in some embodiments of the present application, the connecting cavity 14 includes a first connecting portion 141 and a second connecting portion 142, and the second tubular lumen segment 122, the first connecting portion 141, the second connecting portion 142 and the suction hole 13 are connected in sequence, wherein, along the axial direction of the second tubular lumen segment 122, the size L1 of the first connecting portion 141 is respectively smaller than the size L2 of the second connecting portion 142, smaller than the size L3 of the suction hole 13, and smaller than the size L4 of the second tubular lumen segment 122.

[0075] Specifically, the end of the connecting lumen 14 proximal to the second lumen section 122 has a minimum opening dimension, thereby preventing the fluid within the second lumen section 122 from sequentially flowing through the connecting lumen 14 and the air inhalation hole 13 to the exterior of the tubular body 11. Furthermore, because the dimension L1 of the first connecting portion 141 is smaller than the dimension L2 of the second connecting portion 142, a curved structure is formed. In some embodiments, this prevents the fluid within the second lumen section 122 from sequentially flowing through the connecting lumen 14 and the air inhalation hole 13 to the exterior of the tubular body 11.

[0076] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the opening area of ​​the suction hole 13 can be consistent with the flow area of ​​the second lumen section 122 , thereby increasing the air intake volume in the lumen 12 .

[0077] Combine Figures 4 to 6 As shown, in some embodiments of the present application, along the axial direction of the second tubular lumen section 122, the projection of the first connecting portion 141 and the projection of the second connecting portion 142 are respectively partially circular, wherein the value range of the central angle a corresponding to the projection of the first connecting portion 141 is 0°<a≤180°, and / or the value range of the central angle b corresponding to the projection of the second connecting portion 142 is 0°<b≤180°.

[0078] That is, the first connecting portion 141 can be a fan-shaped structure, or a semicircular ring structure, and / or the second connecting portion 142 can be a fan-shaped structure, or a semicircular ring structure, thereby increasing the flow area of ​​the connecting cavity 14 and further increasing the air intake of the lumen 12.

[0079] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the central angle a corresponding to the projection of the first connecting portion 141 is 180°, the central angle b corresponding to the projection of the second connecting portion 142 is 180°, the second tubular lumen segment 122 is a circular tubular lumen segment, the diameter R of the second tubular lumen segment 122 is consistent with the axial dimension L4 of the second tubular lumen segment 122, the second tubular lumen segment 122 has a flow area S1, and the first connecting portion 141 has a minimum flow area S2, wherein S1 is greater than S2.

[0080] Specifically, the first connecting portion 141 and the second connecting portion 142 are both semicircular structures. By setting S1 to be larger than S2, the flow area of ​​the first connecting portion 141 is smaller than the flow area of ​​the second lumen section 122, thereby reducing the occurrence of fluid in the second lumen section 122 flowing out of the tube body 11 through the first connecting portion 141 and the air intake hole 13.

[0081] Specifically, the ratio of S1:S2 is 4:1. The diameter of the second tubular lumen section 122 is R, and the flow area of ​​the second tubular lumen section 122 is S1=πR 2The arc length of the first communication portion 141 is πR, the axial dimension of the first communication portion 141 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 also 4:1. Furthermore, since the axial dimension L4 of the second lumen segment 122 is equal to the diameter of the second lumen segment 122, both being R, L4 is equal to L1 of the axial dimension L4.

[0082] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the air intake hole 13 is a circular hole, and the diameter L3 of the air intake hole 13 is in the range of 2 mm ≤ L3 ≤ 3.6 mm.

[0083] In some embodiments of the present application, the opening area of ​​the suction hole 13 is consistent with the flow area of ​​the second lumen segment 122. Therefore, R can be consistent with the value of L3, that is, 2mm≤R≤3.6mm. In addition, in some embodiments of the present application, the axial dimension L4 of the second lumen segment 122 is equal to the diameter R of the second lumen segment 122. Therefore, 2mm≤L4≤3.6mm.

[0084] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the end of the third tubular cavity segment 123 away from the second tubular cavity segment 122 is provided with a liquid outlet 17 connected to the tubular cavity 12, and the axis of the suction hole 13 is set at an angle of 90° to 180° to the axis of the liquid outlet 17.

[0085] That is, along the circumferential direction of the second tubular lumen section 122, the liquid outlet 17 and the air intake hole 13 are arranged at an angle of 90° to 180°, thereby reducing the possibility of fluid flowing through the liquid outlet 17 and then flowing into the air intake hole 13 under the influence of airflow. Specifically, the angle between the liquid outlet 17 and the air intake hole 13 can be any value between 90°, 120°, 150°, and 180°. When the liquid outlet 17 and the air intake hole 13 are arranged at an angle of 180°, the possibility of fluid flowing through the liquid outlet 17 and then flowing into the air intake hole 13 under the influence of airflow can be minimized.

[0086] Combine Figures 2 to 6 As shown, in some embodiments of the present application, a fixing portion 15 is protruding from the outer surface of the tube body 11 , and along the axial direction of the second tube cavity section 122 , the liquid outlet 17 and the air suction hole 13 are both arranged on the same side of the fixing portion 15 .

[0087] Specifically, the fixing portion 15 is used to fix the overall installation position of the first nozzle 10. Since the clothing treatment drum 104 will rotate during the washing process, the first nozzle 10 is not suitable for directly passing through the clothing treatment drum 104 and being inserted into the clothing treatment cavity 1041. In some embodiments of the present application, the first nozzle 10 may be provided on the door seal 105 at the front end of the clothing treatment drum 104, and the front end of the clothing treatment drum 104 is one end facing the door body 103. The fixing portion 15 is snapped onto the inside of the door seal 105, and the end of the first nozzle 10 provided with the liquid outlet 17 passes through the door seal 105 and is arranged toward the inside of the clothing treatment cavity 1041. The first nozzle 10 dispenses detergent into the clothing treatment cavity 1041 by spraying, and the other end of the first nozzle 10 is provided on the outside of the door seal 105 and is used to communicate with the first liquid supply pipe 30. The liquid outlet 17 and the air intake hole 13 are jointly arranged on the same side of the fixed part 15 facing the clothing processing chamber 1041, that is, the liquid outlet 17 and the air intake hole 13 are jointly arranged on the inner side where the door seal 105 is connected to the clothing processing chamber 1041. Even if fluid leakage occurs at the air intake hole 13, the leaked fluid will not fall onto other electrical components outside the clothing processing drum 104, thereby reducing the occurrence of safety accidents.

[0088] In some embodiments of the present application, the maximum distance between the air suction hole 13 and the fixing portion 15 is smaller than the minimum distance between the liquid outlet 17 and the fixing portion 15 .

[0089] When the first nozzle 10 is installed inside the laundry processing device 1, the first nozzle 10 is arranged in a substantially vertical direction or at an angle to the vertical direction. In the vertical direction, the liquid outlet 17 is located at the bottom end of the first nozzle 10, the air intake hole 13 is located above the liquid outlet 17, and the fixing portion 15 is located above the air intake hole 13. The maximum spacing between the air intake hole 13 and the fixing portion 15 is smaller than the minimum spacing between the liquid outlet 17 and the fixing portion 15. That is, no position on the air intake hole 13 is located below the liquid outlet 17, thereby reducing the phenomenon of fluid flowing out of the liquid outlet 17 and then flowing into the air intake hole 13 under the action of airflow.

[0090] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the tubular cavity 12 also includes a fourth tubular cavity segment 124, which is arranged at one end of the first tubular cavity segment 121 away from the second tubular cavity segment 122, and the fourth tubular cavity segment 124 is provided with a liquid inlet 16 connected to the tubular cavity 12.

[0091] Specifically, a liquid inlet 16 is provided at the top of the fourth lumen section 124. The first nozzle 10 is connected to the first liquid supply pipe 30 via the liquid inlet 16, thereby being used to deliver fluid into the lumen 12. The fourth lumen section 124 is generally a straight lumen section, thereby facilitating fluid delivery or facilitating the provision of other structures within the fourth lumen section 124.

[0092] Combine Figures 4 to 6 As shown, in some embodiments of the present application, a flow-disturbing structure 18 is further provided in the lumen 12 so that the fluid flowing through the flow-disturbing structure 18 in the lumen 12 has a component velocity along the circumferential direction of the lumen 12 .

[0093] By arranging a flow-turbulating structure 18 in the tube cavity 12 of the first nozzle 10, the fluid flowing through the flow-turbulating structure 18 in the tube cavity 12 has a component velocity along the circumferential direction of the tube cavity 12. When the fluid flows out through the tube cavity 12, such as the detergent and / or washing water flows out through the tube cavity 12, the component velocity along the circumferential direction of the tube cavity 12 can increase the injection angle of the fluid, thereby increasing the injection area of ​​the first nozzle 10, and further increasing the contact area between the detergent and / or washing water and the clothes, increasing the utilization rate of the detergent and / or washing water, and improving the washing effect of the clothes.

[0094] Specifically, the flow-disturbing structure 18 can be provided in the fourth lumen section 124. During the flow of the fluid in the lumen 12, the flow-disturbing structure 18 first forms a component velocity along the circumferential direction of the lumen 12. Then, the air content in the fluid is increased by the air supply function of the air intake hole 13. When the fluid is ejected from the liquid outlet 17, the injection angle can be spread along the circumferential direction of the lumen 12, and a large number of bubble structures are formed, thereby effectively increasing the contact area between the medium and the clothes, such as the contact area between the detergent and / or washing water and the clothes, thereby increasing the utilization rate of the detergent and / or washing water and improving the washing effect of the clothes.

[0095] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the flow-disrupting structure 18 includes at least one spoiler 181, and the surface of the spoiler 181 is arranged at an angle to the axial direction of the lumen 12. Because the surface of the spoiler 181 is arranged at an angle to the axial direction of the lumen 12, when the fluid flows through the spoiler 181, the fluid can flow along the surface of the spoiler 181 due to the action of the spoiler 181, so that the flow direction of the fluid is arranged at an angle to the axial direction of the lumen 12, thereby causing the fluid to have a component velocity along the circumferential direction of the lumen 12.

[0096] Combine Figures 4 to 6As shown, in some embodiments of the present application, the spoiler structure 18 includes a plurality of spoilers 181, which are arranged at intervals along the circumference of the lumen 12, and the angle between the plate surface of any spoiler 181 and the axial direction of the lumen 12 is the same.

[0097] By simultaneously arranging a plurality of spoilers 181, the turbulent effect of the turbulent structure 18 can be improved, thereby increasing the diffusion spray angle of the detergent and / or washing water along the circumferential direction of the tube cavity 12 after being sprayed out from the liquid outlet 17, increasing the contact area between the detergent and / or washing water and the clothes, increasing the utilization rate of the detergent and / or washing water, and improving the washing effect of the clothes.

[0098] Combine Figures 4 to 6 As shown, in some embodiments of the present application, the spoiler structure 18 further includes a connecting ring 182 , which is provided with a first through hole 183 along the axial direction of the lumen 12 , and one end of a plurality of spoilers 181 is respectively connected to the outer peripheral surface of the connecting ring 182 .

[0099] Specifically, one end of each of the plurality of spoilers 181 is connected to a connecting ring 182, and the other ends of each of the plurality of spoilers 181 are connected to the inner wall of the lumen 12. The connecting ring 182 simultaneously secures the plurality of spoilers 181, thereby allowing the plurality of spoilers 181 to be spaced apart along the circumference of the connecting ring 182. Furthermore, a first through-hole 183 is formed through the connecting ring 182 in the axial direction. This allows the medium at the center of the lumen 12 to flow through the connecting ring 182 via the first through-hole 183, and allows the medium at the circumferential edge of the lumen 12 to have a component velocity along the circumference of the lumen 12 due to the disruptive effect of the spoilers 181.

[0100] In some embodiments of the present application, the structure of the connecting ring 182 can also be eliminated, and one end of multiple spoilers 181 can be connected to the inner wall surface of the lumen 12 respectively, and the other end can be suspended in the air. Similarly, multiple spoilers 181 can be spaced apart in the circumferential direction of the lumen 12.

[0101] like Figure 7 As shown, in some embodiments of the present application, there are two spoilers 181 , which are spaced apart along the circumferential direction of the lumen 12 , and staggered along the axial direction of the lumen 12 .

[0102] Specifically, one end of each of the two spoilers 181 is connected to the inner wall of the lumen 12, while the other ends of each of the two spoilers 181 are spaced apart from the inner wall of the lumen 12. The two spoilers 181 are spaced 180 degrees apart from each other, with one spoiler 181 at least partially positioned above the other spoiler 181. When fluid flows into the lumen 12 through the liquid inlet 16, the fluid first collides with the upper spoiler 181, thereby generating a component velocity along the circumferential direction of the lumen 12. As the fluid then falls, it collides with the lower spoiler 181, increasing the component velocity of the fluid along the circumferential direction of the lumen 12.

[0103] In some embodiments of the present application, in order to increase the probability of the fluid colliding with the two spoilers 181 in sequence while flowing through the lumen 12, the dimensions of the two spoilers 181 along the radial direction of the lumen 12 respectively exceed the radius dimension of the lumen 12, that is, the two spoilers 181 are partially overlapped in the axial direction of the lumen 12.

[0104] like Figure 8 As shown, in some embodiments of the present application, the flow-disturbing structure 18 is connected to the inner wall surface of the lumen 12 , and the flow-disturbing structure 18 forms at least one flow-disturbing channel 185 , and the axial direction of the flow-disturbing channel 185 is set at an angle to the axial direction of the lumen 12 .

[0105] Specifically, one or more flow-turbulating channels 185 can be set in the tubular cavity 12 at the same time, and the axial direction of the flow-turbulating channel 185 is set at an angle to the axial direction of the tubular cavity 12, so that the fluid can form a component velocity along the circumferential direction of the tubular cavity 12 when flowing through the flow-turbulating channel 185 during the process of flowing through the tubular cavity 12.

[0106] The flow-disrupting structure 18 may include a mounting block 184 , the outer wall of which is fitted against the inner wall of the lumen 12 , and at least two flow-disrupting channels 185 are provided through the mounting block 184 , with at least two flow-disrupting channels 185 intersecting with each other.

[0107] By fitting the outer wall of the mounting block 184 against the inner wall of the lumen 12, no space for fluid circulation is left between the mounting block 184 and the lumen 12. Consequently, the fluid in the lumen 12 can flow out only through the flow-disrupting channels 185, resulting in most or even all of the fluid in the lumen 12 having a component velocity along the circumferential direction of the lumen 12. Furthermore, at least two flow-disrupting channels 185 intersect, meaning that the fluid flowing out of the flow-disrupting channels 185 can flow out in different directions. This increases the probability of collisions after the fluid flows out of the flow-disrupting channels 185 and improves the component velocity of the fluid along the circumferential direction of the lumen 12.

[0108] Combine Figures 5 to 8As shown, the communication cavity 14 in the above embodiments includes a first communication portion 141 and a second communication portion 142, respectively, to reduce leakage of the lumen 12 through the suction hole 13. In some embodiments of the present application, the structure of the communication cavity 14 can also be simplified.

[0109] like Figure 9 As shown, in some embodiments of the present application, the air intake hole 13 communicates with the second lumen section 122 via a connecting lumen 14. The connecting lumen 14 can be a straight lumen or a partially circular lumen, thereby eliminating the need for a first connecting portion 141 and a second connecting portion 142. The air intake hole 13 can be a circular or square hole, and the flow area of ​​the air intake hole 13 gradually decreases from the exterior toward the interior of the tube body 11, similarly reducing leakage from the lumen 12 through the air intake hole 13.

[0110] like Figure 9 As shown, in some embodiments of the present application, one end of the first tubular lumen segment 121 close to the second tubular lumen segment 122 is tilted toward the liquid outlet 17, so that in the process of the fluid flowing through the first tubular lumen segment 121 to the second tubular lumen segment 122, the component velocity of the fluid flowing toward the liquid outlet 17 can be increased, thereby increasing the injection angle of the fluid and increasing the injection area of ​​the first nozzle 10.

[0111] Combine Figure 2 and Figure 3 As shown, in some embodiments of the present application, an air intake structure may be further provided on the first liquid supply pipe 30. The air intake structure includes a communication hole (not shown in the figure), which is provided on the side wall of the first liquid supply pipe 30 and connects the interior and exterior of the first liquid supply pipe 30. Gas outside 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, and further increasing the gas content of the detergent and / or washing water in the first liquid supply pipe 30, thereby increasing the number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10, increasing the contact area between the detergent and / or washing water and the clothes, and improving the washing effect of the clothes.

[0112] Combine Figure 2 and Figure 3 As shown, in some embodiments of the present application, the air intake structure further includes a gas supply assembly (not shown in the figure), which is disposed outside the first liquid supply pipe 30 and communicates with the interior of the first liquid supply pipe 30 through a communication hole. The gas supply assembly can be a gas supply pump, which is used to pump gas into the interior of the first liquid supply pipe 30, thereby increasing the gas content in the first liquid supply pipe 30, and further increasing the gas content of the detergent and / or washing water in the first liquid supply pipe 30.

[0113] Combine Figures 2 to 9As shown, in some embodiments of the present application, the interior of the first liquid supply pipe 30 includes a first liquid supply section (not shown in the figure), a second liquid supply section (not shown in the figure) and a third liquid supply section (not shown in the figure) that are connected and communicated in sequence. Along the direction of the first liquid supply section toward the second liquid supply section, the flow area of ​​the first liquid supply section gradually decreases, and along the direction of the second liquid supply section toward the third liquid supply section, the flow area of ​​the third liquid supply section gradually increases, and the connecting port is connected to the second liquid supply section.

[0114] The connection structure of the first liquid supply segment, the second liquid supply segment and the third liquid supply segment may be consistent with the connection structure of the first tubular cavity segment 121, the second tubular cavity segment 122 and the third tubular cavity segment 123 in any of the above embodiments.

[0115] By arranging the first, second, and third liquid supply sections according to the above-described structure, the interior of the first liquid supply pipe forms a structure similar to a Venturi tube, and a corresponding Venturi effect can be generated. Because the second liquid supply section is narrower than the first and third liquid supply sections, by connecting the connecting hole to the second liquid supply section, when a fluid, such as detergent and / or washing water, flows through the first liquid supply pipe 30, the Venturi effect within the first liquid supply pipe 30 allows external gas to enter the first liquid supply pipe 30 through the connecting hole, thereby increasing the gas content in the detergent and / or washing water in the first liquid supply pipe 30, thereby increasing the number of bubbles formed by the detergent and / or washing water sprayed from the first nozzle 10, increasing the contact area between the detergent and / or washing water and the clothes, and improving the washing effect of the clothes.

[0116] Combine Figure 2 、 Figure 3 and Figure 10 As shown, in some embodiments of the present application, the detergent dispensing device 101 also includes a mixer 40, which is arranged on the outside of the detergent box assembly 20, and a mixing chamber is formed inside the mixer 40. The mixer 40 also includes a first inlet 41, a second inlet 42 and a first outlet 43 connected to the mixing chamber. The first inlet 41 is used to be connected to an external water supply pipeline, the second inlet 42 is connected to the detergent chamber inside the detergent box assembly, and the first outlet 43 is connected to the first liquid supply pipe 30.

[0117] Specifically, washing water can enter the mixing chamber through the first inlet 41, and the detergent in the detergent chamber can enter the mixing chamber through the second inlet 42. After the detergent and washing water mix with each other in the mixing chamber, a mixed liquid of detergent and washing water is formed, which is transported to the first liquid supply pipe 30 through the first outlet 43, thereby delivering the mixed liquid of detergent and washing water to the clothing treatment chamber 1041 through the first nozzle 10. Among them, the first inlet 41 can be connected to the external water supply pipeline through the water inlet valve 50, and the water inlet valve 50 controls whether to inject washing water into the mixing chamber. The water inlet valve 50 can also be connected to other pipeline components and is used to supply water to other pipeline components. The second inlet 42 can be connected to the detergent chamber inside the detergent box assembly 20 through the liquid pumping assembly 60, and the liquid pumping assembly 60 is used to pump the detergent in the detergent chamber into the mixer 40.

[0118] By pre-mixing the detergent and wash water in the mixing chamber before discharging them into the clothing processing chamber 1041, the mixing effect is more uniform, and the contact area between the detergent and the clothes is more uniform, compared to adding the detergent and wash water separately into the clothing processing chamber 1041 and then mixing them, thereby improving the washing effect of the clothes. At the same time, the detergent in the mixing chamber is impacted by the wash water, which can reduce the amount of detergent remaining in the mixing chamber, thereby improving the utilization rate of the detergent.

[0119] Combine Figure 1 and Figure 2 As shown, in some embodiments of the present application, the clothing processing device 1 also includes a second pipe assembly, one end of the second pipe assembly is used to connect to the external water supply unit, and the other end of the second pipe assembly is used to spray washing water toward the glass of the door body 103 of the clothing processing device 1.

[0120] Specifically, in some embodiments of the present application, a door glass is provided at a position on the door body 103 corresponding to the loading port of the laundry processing chamber 1041, through which the user can observe the washing condition of the laundry in the laundry processing chamber 1041. To improve the cleanliness of the door glass and enhance the observation of the washing condition of the laundry in the laundry processing drum 104, a second pipe assembly is used to flush the door glass from the interior of the laundry processing apparatus 1.

[0121] The second piping assembly may include a second liquid supply pipe 70 and a second nozzle (not shown). One end of the second liquid supply pipe 70 may be connected to an external water supply unit via a water inlet valve 50, and the other end of the second liquid supply pipe 70 may be connected to a second nozzle, which sprays wash water toward the door glass of the door body 103 of the laundry treatment apparatus 1. The second liquid supply pipe 70 may be located outside the detergent box assembly 20 and, depending on positioning requirements, may be fixed to one or more of the housing 102, the laundry treatment drum 104, and the detergent box assembly 20. The second nozzle is fixed to the door seal 105, with its outlet facing the door glass of the door body 103.

The water pump 106 is used to pump the wastewater generated after washing clothes in the laundry processing drum 104 back into the laundry processing chamber 1041 through the third piping assembly. During the process of pumping the wastewater back into the laundry processing chamber 1041, it is filtered by a filter element to remove impurities contained therein. After filtration, the wastewater can be used again for laundry washing. The laundry processing drum 104 includes an inner drum and an outer drum nested together, with a water storage chamber formed between the outer and inner drums. The inner drum is used for washing clothes, and the wastewater after washing is discharged into the water storage chamber between the inner and outer drums. The water pump 106 has a first water inlet (not shown) and a first water outlet (not shown). The first water inlet is connected to the water storage chamber, and the first water outlet is connected to the third piping assembly. Thus, the water inlet is used to pump the wastewater in the water storage chamber back to the laundry processing chamber 1041 for further use, thereby improving the utilization rate of the washing water.

[0123] Among them, the third pipeline assembly may include a third liquid supply pipe 107 and a third nozzle (not shown in the figure), one end of the third liquid supply pipe 107 is connected to the first water outlet, and the other end of the third liquid supply pipe 107 is connected to the third nozzle, and the outlet of the third nozzle is arranged toward the interior of the clothing processing chamber 1041, thereby spraying washing water into the interior of the clothing processing chamber 1041.

[0124] In some embodiments of the present application, a filter may be provided in the connection between the third liquid supply pipe 107 and the third nozzle to remove debris and impurities mixed in the wastewater. The filter may be provided within the detergent box assembly 20. Wastewater in the third liquid supply pipe 107 is filtered by the filter before being sprayed into the clothing treatment chamber 1041 through the third nozzle for use in washing clothes, thereby improving the utilization rate of the washing water. The third nozzle is fixed to the door seal 105, and its outlet is disposed toward the interior of the clothing treatment chamber 1041.

[0125] In some embodiments of the present application, the water pump 106 also includes a second water outlet 1061, which can be connected to a drainage pipe. The wastewater in the water storage chamber can be discharged to the outside of the clothing processing device 1 through the second water outlet 1061 and the drainage pipe under the action of the water pump 106.

[0126] Combine Figure 2 、 Figure 3 、 Figure 11 and Figure 12 As shown, in some embodiments of the present application, the detergent box assembly 20 further includes a first chamber 22 , which is disposed outside the box body 21 , and one end of the first pipe assembly is connected to the detergent chamber through the first chamber 22 .

[0127] Specifically, the interior of the box body 21 is provided with a first detergent chamber for storing liquid detergent. The first chamber 22 is connected to the first detergent chamber, and the liquid detergent in the first detergent chamber can enter the first chamber 22. One end of the first liquid supply pipe 30 is connected to the first chamber 22, and the other end of the first liquid supply pipe 30 is connected to the first chamber 22, and the detergent is dispensed into the clothing treatment chamber 1041 through the first nozzle 10. The detergent dispensing device 101 also includes a first water inlet pipe 51, which can be connected to an external water supply unit via an inlet valve 50 and is used to pass wash water into the first chamber 22. Under the impact of the wash water, the detergent can be dispensed into the clothing treatment chamber 1041 through the first pipeline assembly.

[0128] Among them, an air intake structure is provided on the first liquid supply pipe 30 and / or the first nozzle 10, and the air intake structure can be consistent with the air intake structure in any of the above-mentioned embodiments, thereby increasing the gas content of the detergent in the first pipeline assembly, and then increasing the number of bubbles formed by the detergent released, increasing the contact area between the detergent and the clothes, improving the utilization rate of the detergent, and enhancing the washing effect of the clothes.

[0129] At the same time, since the first pipeline assembly is fixed to the detergent box assembly 20 and is connected to the external water supply pipeline through the first chamber 22, the setting of the connecting pipeline and the mixer 40 is reduced, and the positioning and assembly of the first pipeline assembly are facilitated.

[0130] Combine Figure 2 、 Figure 11 and Figure 12 As shown, the detergent box assembly 20 further includes a liquid pumping assembly 60, which is used to pump the detergent in the first detergent cavity into the first chamber 22. The liquid pumping assembly 60 can be a liquid pump.

[0131] Combine Figure 2 、 Figure 11 and Figure 12As shown, in some embodiments of the present application, a pressure relief hole 222 is further provided in the first chamber 22. When the amount of water flowing into the first chamber 22 is too large, the pressure in the first chamber 22 increases, and the pressure relief hole 222 opens under the action of the increased pressure in the first chamber 22. Part of the detergent and washing water can flow out through the pressure relief hole 222 into the water storage chamber between the inner drum and the outer drum, so as to soak and wash the clothes.

[0132] Combine Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, in some embodiments of the present application, a second detergent chamber for storing solid detergent is provided inside the box body 21, and a second chamber 23 is further provided inside the detergent box assembly 20, and the second chamber 23 is connected to the second detergent chamber. The second chamber 23 is provided outside the box body 21 and is connected to the external water supply unit through the second water inlet pipe 52. Among them, the first chamber 22 and the second chamber 23 are not connected to each other, and the detergent dispensing device 101 also includes a second pipeline assembly, and the second pipeline assembly is connected to the external water supply unit through the second chamber 23. Among them, Figure 11 The direction indicated by the black straight arrow is the direction of water flow in the first chamber 22 and the second chamber 23 .

[0133] Specifically, one end of the second liquid supply pipe 70 is connected to the second chamber 23, and the other end of the second liquid supply pipe 70 sprays wash water toward the door glass of the door body 103 through the second nozzle, thereby cleaning the door glass of the door body 103. The detergent dispensing device 101 also includes a second water inlet pipe 52, which can be connected to the external water supply unit through the water inlet valve 50 and is used to pass wash water into the second chamber 23.

[0134] By fixing the second pipeline assembly on the detergent box assembly 20 and connecting it with the external water supply pipeline through the second chamber 23, the setting of the connecting pipeline is reduced and the positioning and assembly of the second pipeline assembly are facilitated.

[0135] In some embodiments of the present application, the first nozzle 10 and the second nozzle can be independent structures or can be an integrated nozzle body 80.

Part of the washing water entering the second chamber 23 through the second water inlet pipe 52 can be sprayed out through the second pipe assembly and used to rinse the door glass of the door body 103. Another part of the washing water can be passed into the second connecting section 232 and fall into the second detergent chamber through the conducting hole and used to dissolve the solid detergent. The dissolved detergent can enter the water storage chamber between the inner drum and the outer drum to wash the clothes. Among them, the water inlet valve 50 can control the first water inlet pipe 51 and the second water inlet pipe 52 to inlet water together, or the water inlet valve 50 can control the first water inlet pipe 51 and the second water inlet pipe 52 to inlet water separately, so as to achieve different water supply modes and detergent supply modes.
