Description

Technical Field

[0001] This application relates to the field of clothing processing, and more particularly to a detergent dispensing device and clothing processing equipment. Background Technology

[0002] In related technologies, clothing processing equipment mainly includes a clothing processing drum, a detergent dispenser, and piping, with the piping connecting the detergent dispenser and the clothing processing drum. During washing, external fluid is introduced into the detergent dispenser to form a detergent solution, which is then introduced into the clothing processing drum through the piping, thus adding detergent. However, detergents, especially laundry powder, often do not dissolve completely or mix unevenly with the fluid, resulting in insufficient detergent utilization, poor cleaning performance, and a negative impact on user experience. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a detergent dispensing device and a clothing treatment device, which fully dissolves detergent, especially powdered detergent, and then dispenses it into the clothing treatment chamber, thereby improving the degree of detergent dissolution and cleaning effect, and enhancing the user experience.

[0004] The first aspect of this application provides a detergent dispensing device, comprising:

[0005] A detergent supply assembly has a detergent passage and a first drain outlet, the detergent passage being connected to the external space of the detergent dispensing device;

[0006] The liquid outlet channel has an inlet and an outlet.

[0007] The first water passage and the second water passage are used to transport fluid. The first water passage is connected to the water source, the detergent passage, the first drain outlet, and the inlet of the liquid outlet water passage. The second water passage is connected to the water source and the inlet of the liquid outlet water passage.

[0008] The fluid in the first water path and the fluid in the second water path converge in the liquid outlet water path, and the fluid in the first water path is a detergent mixture solution.

[0009] In some implementations, the outlet pressure of the second water passage is greater than the outlet pressure of the first water passage.

[0010] In some implementations, the first drain outlet is higher than the inlet end of the liquid outlet path in the direction of gravity, so that the detergent mixture in the first path merges with the fluid in the second path in the liquid outlet path under the action of gravity.

[0011] In some implementation schemes, the outlet end of the second water passage is provided with a narrowing section to increase the flow velocity at the outlet end of the second water passage.

[0012] In some implementations, the end of the narrowed section forms the outlet of the second water passage; or, the end of the narrowed section is further connected to a constant diameter section and / or an expanded diameter section, the constant diameter section and / or the expanded diameter section forming the outlet of the second water passage.

[0013] In some implementations, the extension lengths of the equal-diameter section and the expanded-diameter section along the second waterway are both less than or equal to the extension length of the reduced-diameter section along the second waterway.

[0014] In some embodiments, the detergent dispensing device further includes a turbulence structure disposed in the second water channel for providing a circumferential velocity component to the fluid in the second water channel.

[0015] In some implementations, the turbulent structure includes one or more helical blades for guiding the helical motion of the fluid.

[0016] In some embodiments, the outer edge of the helical blade along the helical direction is connected to the inner wall of the second water passage, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the second water passage.

[0017] In some implementations, the narrowed section is located downstream of the turbulent structure.

[0018] In some embodiments, the detergent supply assembly further includes an overflow chamber for receiving detergent mixture overflowing from the detergent passage, and a second drain for discharging the detergent mixture from the overflow chamber.

[0019] In some embodiments, the detergent supply assembly includes a detergent cartridge and a dispenser box disposed within the detergent cartridge. The dispenser box has a detergent dispensing chamber, a mixing chamber, and an overflow chamber. The mixing chamber and the overflow chamber are located below the dispenser box. The mixing chamber is used to collect detergent mixture flowing through the detergent dispensing chamber. A first drain outlet is disposed on the wall of the mixing chamber. The overflow chamber is used to collect detergent mixture overflowing from the mixing chamber.

[0020] In some implementations, the detergent dispensing device includes a first pipeline and a second pipeline. One end of the first pipeline is connected to a water source, and the other end of the first pipeline is connected to the detergent supply component. One end of the second pipeline is connected to the first drain outlet, and the other end is connected to the liquid outlet water path.

[0021] In some embodiments, the detergent dispensing device includes a third conduit, one end of which is connected to a water source and the other end is connected to the liquid outlet water path; the space within the third conduit independently defines the second water path, or the space within the third conduit defines a portion of the second water path.

[0022] This application embodiment also provides a garment processing device, including:

[0023] Garment processing chamber;

[0024] The detergent dispensing device described in any embodiment of this application;

[0025] The outlet end of the liquid outlet path is connected to the clothing processing chamber.

[0026] In some embodiments, the garment handling device includes a door seal ring having an mounting port, the outlet end of the liquid outlet passage passing through the mounting port and extending into the radially inner side of the door seal ring.

[0027] In the detergent dispensing device of this application embodiment, the first water path flows through a detergent passage connected to the external space of the detergent dispensing device, causing the fluid in the first water path to be depressurized. The second water path does not flow through the first drain outlet, thereby creating a pressure difference between the end of the first water path and the end of the second water path, and thus a flow velocity difference. This flow velocity difference allows the detergent carried in the first water path to be further impacted, diluted, dissolved, and mixed by the fluid in the second water path with a higher flow velocity in the liquid outlet water path. In this way, before the detergent enters the clothing processing chamber, the dissolution of the detergent can be further promoted, the mixing uniformity of the detergent and water can be improved, thereby improving the utilization efficiency of the detergent and the washing ratio.

[0042] This application provides a detergent dispensing device 100. Please refer to [link / reference]. Figure 2 as well as Figures 6 to 8 The detergent dispensing device 100 includes a detergent supply component, a liquid outlet water path 20, a first water path 40A, and a second water path 50A. The detergent supply component has a detergent passage and a first drain outlet. The first water path 40A and the second water path 50A are used to transport fluid.

[0043] This application also provides a clothing processing device. The type of clothing processing device is not limited, for example, it can be a washing machine, a washer-dryer combo, etc.

[0044] Please see Figure 1 and Figure 2 The garment processing equipment includes a garment processing chamber and a detergent dispensing device 100 as described in any embodiment of this application. The outlet end of the liquid outlet channel 20 of the detergent dispensing device 100 is connected to the garment processing chamber.

[0045] It is understandable that the detergent pathway refers to the flow path of the detergent mixture solution within the detergent supply assembly.

[0046] It should be noted that the detergent mixture mentioned in this specification is for ease of description only, referring to a solution containing dissolved detergent, and its mass percentage concentration is not limited. Of course, a detergent mixture does not necessarily mean that the detergent is completely dissolved. In some embodiments, the detergent mixture may be the undiluted detergent added by the user. In other embodiments, after the user adds the detergent to the detergent dispensing device, the detergent is mixed with fluid from a water source.

[0047] The first water path 40A connects the water source, the detergent passage, the first drain outlet, and the inlet of the liquid outlet water path 20. In other words, the fluid in the first water path 40A flows through the detergent passage and the first drain outlet, meaning that the detergent passage and the first drain outlet constitute a part of the first water path 40A.

[0048] The second waterway 50A connects the water source and the inlet of the outlet waterway 20.

[0049] The fluid in the first water channel 40A and the fluid in the second water channel 50A converge in the outlet water channel 20. The fluid in the first water channel 40A is a detergent mixture solution. The fluid in the second water channel 50A is not limited; it can be water, a detergent mixture solution, or a solution with other care ingredients added.

[0050] In other words, in the first water path 40A, the fluid from the water source flows through the detergent container and mixes with the detergent to form a detergent mixture solution. This detergent mixture solution flows to the first drain outlet and is discharged through it, then flows to the liquid outlet water path 20. Please refer to [link / reference]. Figures 2 to 8 In the accompanying drawings of this manual, the arrows and dashed lines indicate the direction of liquid flow.

[0051] For example, the detergent passage includes a detergent dispensing chamber, which can be adapted to hold powdered laundry detergent. When the fluid from the first water passage 40A flows through the detergent dispensing chamber, it initially dissolves the laundry detergent. Of course, the detergent dispensing chamber can also be adapted to hold detergents with flow characteristics, such as liquid laundry detergent, fabric softener, perfume, etc.

[0052] In this embodiment, the detergent passage is connected to the external space of the detergent dispensing device, meaning the detergent passage is connected to the atmospheric environment, forming a pressure relief space. The initial water pressure of the fluid in the first water passage 40A at any cross-section where it connects to the water source is the initial water pressure. When the fluid in the first water passage 40A flows through the detergent passage, the fluid enters the pressure relief space from the closed pipe section, causing a drop in the water pressure of the first water passage 40A, i.e., pressure relief occurs. The depressurized fluid flows from the first drain outlet to the inlet of the outlet water passage 20, resulting in the water pressure at any cross-section of the inlet of the outlet water passage 40A being lower than the initial water pressure at any cross-section where it connects to the water source. In other words, the fluid from the water source enters the first water passage 40A at a relatively high pressure, undergoes pressure relief in the detergent passage, and thus the water pressure at the end of the first water passage 40A is lower than the water pressure at its inlet.

[0053] It should be noted that the specific type of fluid in the second water channel 50A is not limited. For example, it can be water or a washing medium mixture solution. This washing medium mixture solution can be the same as or different from the detergent mixture solution in the first water channel 40A. In some preferred embodiments, the fluid in the second water channel 50A is water. In the following embodiments, water is used as an example for description. It should be noted that in the embodiments of this application, the first water channel 40A refers to the flow path of the fluid and does not specifically refer to a pipe structure. The second water channel 50A refers to the flow path of the fluid and does not specifically refer to a pipe structure.

[0054] It should be noted that the aforementioned water source refers to the water source supplying fluid to the first water channel 40A and the second water channel 50A. This can be, for example, tap water, or an internal water source such as circulating water from the laundry processing equipment. The first water channel 40A and the second water channel 50A can be connected to the same water source or different water sources. For an example, please refer to [link to example]. Figure 2 The garment processing equipment includes an inlet valve 90 connected to a water source. The first water path 40A and the second water path 50A can be connected to different inlet valves 90, or they can be connected to the same inlet valve 90; this is not limited here. As an optional embodiment, the garment processing equipment includes a circulation pump (not shown). One of the first water path 40A and the second water path 50A is connected to the inlet valve 90, while the other of the first water path 40A and the second water path 50A is connected to the outlet of the circulation pump (not shown) of the garment processing equipment.

[0055] Understandably, after the first water path 40A flows through the detergent passage and the first drain outlet, it continues to flow carrying the detergent mixture into the liquid outlet water path 20. The second water path 50A also enters the liquid outlet water path 20. The first water path 40A and the second water path 50A converge in the liquid outlet water path 20, causing the two streams of water to mix. After mixing, the mixture is discharged from the outlet end of the liquid outlet water path 20 and enters the garment processing chamber. In other words, the liquid outlet water path 20 is used to guide the mixture of the first water path 40A and the second water path 50A into the garment processing chamber.

[0056] In the detergent dispensing device of this application embodiment, the first water path 40A flows through a detergent passage that is connected to the external space of the detergent dispensing device, causing the fluid in the first water path 40A to be depressurized. The second water path 50A does not flow through the first drain outlet, thereby creating a pressure difference between the end of the first water path 40A and the end of the second water path 50A, which in turn leads to a flow velocity difference. This flow velocity difference allows the detergent carried by the first water path 40A to be further impacted, diluted, dissolved, and mixed in the liquid outlet water path 20 by the fluid of the second water path 50A with higher water pressure. In this way, before the detergent enters the clothing processing chamber, the dissolution of the detergent can be further promoted, the mixing uniformity of the detergent and water can be improved, thereby improving the utilization efficiency of the detergent and the washing ratio.

[0057] In some embodiments, the second water path 50A can be connected to the inlet valve 90 to mix with the water in the first water path 40A at a pressure not lower than that of the water flowing in from the inlet valve 90, thereby further improving the mixing effect.

[0058] It should be noted that, in the embodiment where the detergent is laundry powder, some of the laundry powder in the first water channel 40A may not be completely dissolved. When the first water channel 40A and the second water channel 50A are mixed by impact, the impact fluid helps to promote the dissolution of the laundry powder.

[0059] It should be noted that the inlet of the liquid outlet channel 20 refers to the part where water from the first water channel 40A leaves the first water channel 40A and enters the liquid outlet channel 20, and the part where water from the second water channel 50A leaves the second water channel 50A and enters the liquid outlet channel 20. The outlet of the liquid outlet channel 20 refers to the part where water in the liquid outlet channel 20 leaves the liquid outlet channel 20.

[0060] For example, in some embodiments, please refer to Figure 6 The liquid outlet water path 20 includes a mixing space 20a. The wall of the mixing space 20a is provided with two ports 20b. The fluid in the first water path 40A enters the mixing space 20a from one of the ports 20b, and the fluid in the second water path 50A enters the mixing space 20a from the other port 20b. Both ports 20b can be regarded as the outlet of the first water path 40A and the second water path 50A, and also as the inlet of the liquid outlet water path 20. The outlet of the liquid outlet water path 20 is located on the wall of the mixing space 20a.

[0061] In other embodiments, please refer to Figure 7 The liquid outlet water path 20 includes a mixing space 20a. The wall of the mixing space 20a is provided with a port 20b. The fluid in the first water path 40A enters the mixing space 20a through the port 20b. The outlet end of the second water path 50A extends into a certain position in the mixing space 20a. The port 20b of the mixing space 20a can be regarded as the outlet end of the first water path 40A and also the inlet end of the liquid outlet water path 20. The outlet end of the second water path 50A can be regarded as another inlet end of the liquid outlet water path 20. The outlet end of the liquid outlet water path is located on the wall of the mixing space 20a.

[0062] In some other embodiments, please refer to Figure 8The garment processing equipment includes a first tubular structure 1001 and a second tubular structure 1002. At least a portion of the second tubular structure 1002 extends into the interior of the first tubular structure 1001. The liquid outlet path 20 includes a mixing space 20a, which is formed by a portion of the first tubular structure 1001; that is, the mixing space 20a is formed by the first tubular structure 1001 itself. A portion of the first tubular structure 1001 upstream of the mixing space 20a defines a portion of a first water path 40A. A portion of a second water path 50A is formed by the second tubular structure 1002. The outlet end of the second tubular structure 1002 is located within the mixing space 20a formed by the first tubular structure 1001. Fluid in the second water path 50A flows out from the outlet end of the second tubular structure 1002 and converges with the fluid in the first water path 40A within the mixing space 20a formed by the first tubular structure 1001. The upstream water outlet section 1003 of the mixing space 20a formed adjacent to the first tubular structure 1001 can be considered as the water outlet end of the first water path 40A, and also as an inlet end of the liquid outlet water path 20. The water outlet end of the second tubular structure 1002 can be considered as another inlet end of the liquid outlet water path 20. The water outlet end of the liquid outlet water path is located on the first tubular structure 1001.

[0063] For example, the outlet pressure of the second water channel 50A is greater than the outlet pressure of the first water channel 40A. The outlet pressure of the first water channel 40A refers to the dynamic pressure on the cross-section of its outlet end. The outlet pressure of the second water channel 50A refers to the dynamic pressure on the cross-section of its outlet end. Dynamic pressure, a fluid mechanics term, refers to the pressure at a surface directly opposite the direction of fluid movement where the fluid is completely obstructed (the fluid velocity is zero), its kinetic energy is converted into pressure energy, and the pressure increases. This pressure is called the total obstructed pressure (or simply total pressure). The difference between this pressure and the pressure at the undisturbed point (i.e., static pressure) is called the dynamic pressure.

[0064] In this embodiment, since the outlet pressure of the second water channel 50A is greater than the outlet pressure of the first water channel 40A, the impact force of the fluid coming out of the outlet of the second water channel 50A is greater than the impact force of the fluid coming out of the outlet of the first water channel 40A. This can increase the impact force on the fluid coming out of the first water channel 40A, which is more conducive to dispersing the detergent and improving the solubility of the detergent.

[0065] For example, the detergent supply assembly has an overflow chamber and a second drain outlet 30a (see...) Figure 3 ).

[0066] The overflow chamber is used to collect the detergent mixture overflowing from the detergent passage, and the second drain port 30a is used to drain the detergent mixture from the overflow chamber. For example, the second drain port 30a is disposed on the wall of the overflow chamber, and the liquid in the overflow chamber can be directly discharged from the second drain port 30a.

[0067] When the water level in the detergent passage is not higher than the overflow level, the water in the detergent passage is discharged from the first drain outlet and flows to the liquid outlet 20. When the water level in the detergent passage is higher than the overflow level, the excess water overflows into the overflow chamber and is discharged from the detergent supply component through the second drain outlet 30a, thereby reducing fluid blockage in the detergent passage and providing a safety protection function. If the laundry detergent added to the detergent supply component may become damp and clump together, making it difficult to dissolve completely in a short time, the flow rate of the first drain outlet is relatively small, and the overflow chamber and the second drain outlet 30a can also promptly drain the overflow water in the detergent passage.

[0068] In some embodiments, the flow area of ​​the second drain outlet 30a is larger than that of the first drain outlet. That is, when the water volume is equal and sufficient, the drainage volume of the second drain outlet 30a is greater than that of the first drain outlet. The aforementioned flow area refers to the cross-sectional area of ​​the fluid.

[0069] Because the flow area of ​​the first drain outlet is relatively small, the outflow volume of the first drain outlet is relatively small. However, the second drain outlet 30a and the overflow chamber can promptly discharge the detergent mixture or fluid in the first water channel 40A in the event of overflow, further enhancing its safety protection function.

[0070] In some embodiments, such as Figure 1 As shown, the garment processing equipment includes a drum assembly, which includes an outer drum 11 and an inner drum disposed within the outer drum. The inner drum is rotatably disposed within the outer drum 11. The outer drum 11 is used to hold water for washing clothes, and the inner drum is used to hold clothes. In this embodiment, the inner drum holds water through the outer drum 11, and the inner drum can also be referred to as a perforated inner drum. In other embodiments, the inner drum holds water on its own, and can also be referred to as a non-perforated inner drum. The outer drum 11 may or may not be provided outside the inner drum.

[0071] It is understood that in some embodiments, the cylinder assembly 10 may only have an inner cylinder and not the outer cylinder 11 mentioned above. In this embodiment, the inner cylinder is a non-perforated inner cylinder that can hold water on its own.

[0072] The outer tub 11 is provided with a water inlet, and the second drain outlet 30a is connected to the water inlet. For example, the laundry treatment device also includes a water outlet pipe 70 connecting the second drain outlet 30a and the water inlet. When the water level in the detergent passage is higher than the overflow level, the excess water overflows into the overflow chamber and enters the water outlet pipe 70 from the second drain outlet 30a, which can also realize auxiliary water intake.

[0073] For example, please refer to Figure 2 The detergent supply assembly includes a detergent dispenser 30 and a dispenser box (not shown) disposed within the detergent dispenser 30, the dispenser box having a detergent dispensing cavity. In some embodiments, the dispenser box is removably disposed within the detergent dispenser 30, for example, the dispenser box is at least partially pulled out horizontally from the detergent dispenser 30 to the outside of the detergent dispenser 30. The user can then dispense detergent into the detergent dispensing cavity.

[0074] The detergent dispenser 30 has a mixing chamber and an overflow chamber, located below the dispenser box. The mixing chamber is used to collect the detergent mixture flowing through the detergent dispensing chamber, and a first drain outlet is disposed on the wall of the mixing chamber. The overflow chamber is used to collect the detergent mixture overflowing from the mixing chamber. It should be noted that the detergent in the detergent dispensing chamber can flow towards the first drain outlet under the action of the fluid.

[0075] It is understood that the detergent dispensing chamber and the mixing chamber at least form part of the detergent passage. The fluid in the first water path 40A passes through the detergent dispensing chamber and the mixing chamber, and the detergent passage is part of the first water path 40A. No additional pipes are needed for draining the detergent dispensing chamber, making the detergent supply assembly more compact.

[0076] Please see Figure 3 The first drain outlet is higher than the inlet end of the liquid outlet channel 20 in the direction of gravity G, so that the detergent mixture in the first water channel 40A merges with the fluid in the second water channel 50A in the liquid outlet channel 20 under the action of gravity.

[0077] Because of the height difference between the first drain outlet and the inlet of the liquid outlet channel 20, the fluid passing through the first drain outlet accelerates under the action of gravity and mixes with the fluid in the second channel 50A at a certain speed. In this way, the mixing with the fluid in the second channel 50A can be achieved by utilizing gravitational potential energy, eliminating the need for additional water pumps or other electric devices. This allows for powerless mixing, saving costs, simplifying the structure, and enhancing operational stability.

[0078] It should be noted that the liquid outlet water path 20 can be located directly below the first drain outlet or diagonally below the first drain outlet, as long as there is a height difference between the water inlet end of the liquid outlet water path 20 and the first drain outlet along the direction of gravity G.

[0079] In some embodiments, please refer to Figure 3 Any position of the detergent supply component is higher than the inlet end of the outlet water path 20 in the direction of gravity G. The detergent mixture in the detergent supply component has a higher gravitational potential energy than the outlet water path 20, and the acceleration effect of gravity is more obvious when it is discharged through the first drain outlet.

[0080] In some embodiments, any position of the first water path 40A is not lower than the inlet end of the outlet water path 20 in the direction of gravity G. That is, the junction of the outlet water path 20 and the first water path 40A is located at the lowest point of the first water path 40A, so that the detergent mixture in the first water path 40A has less energy loss when it flows into the outlet water path 20.

[0081] In some embodiments, any position of the second water path 50A is not lower than the inlet end of the outlet water path 20 in the direction of gravity G. The junction of the outlet water path 20 and the second water path 50A is located at the lowest point of the second water path 50A, so that when the fluid in the second water path 50A converges at the outlet water path 20, its energy loss is less.

[0082] For example, the flow velocity at the end of the first water path 40A is less than the flow velocity at the end of the second water path 50A. The end of the first water path 40A refers to the point where the fluid in the first water path 40A exits the first water path 40A, which can also be understood as the junction of the first water path 40A and the liquid outlet water path 20. The end of the second water path 50A refers to the point where the fluid in the second water path 50A exits the second water path 50A, which can also be understood as the junction of the second water path 50A and the liquid outlet water path 20.

[0083] The slower-flowing fluid from the first water path 40A in the liquid outlet water path 20 mixes with the faster-flowing fluid from the second water path 50A, which can further promote detergent dissolution.

[0084] In some embodiments, please refer to Figure 4 The detergent dispensing device 100 also includes a turbulence structure 21, which is disposed in the second water channel 50A and is used to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0085] The aforementioned circumferential velocity component refers to the fluid in the second water channel 50A after passing through the turbulent structure 21, whose velocity direction has a non-zero component in the circumferential direction of the second water channel 50A, and the circumferential direction of the second water channel 50A is perpendicular to the extension direction of the second water channel 50A.

[0086] After passing through the turbulent structure 21, the fluid state changes, and it tends to disperse circumferentially, forming multiple streams with different directions. This allows the fluid to enter the outlet water channel 20, where it mixes better with the fluid already there, improving mixing efficiency. Furthermore, it ensures that the fluid sprayed from the outlet end of the outlet water channel 20 disperses in a roughly cone shape, resulting in a wider radiation range and better visual effect.

[0087] Understandably, the turbulent flow structure 21 can also increase the fluid velocity by limiting the flow area of ​​the second water channel 50A in which it is located. This results in a greater difference in velocity between the two fluid streams entering the outlet water channel 20, further promoting detergent dissolution.

[0088] For example, the turbulence structure 21 includes one or more helical blades for guiding the fluid in a helical motion. A helical blade is a blade with a helical shape, extending in the helical direction. After passing through the helical blades, the fluid exhibits a helical motion with a circumferential velocity component. The helical blade structure is simple, provides good turbulence control, and has low resistance, reducing energy loss as the fluid passes through.

[0089] In some embodiments, a helical blade is disposed in the second water passage 50A. The outer edge of the helical blade along the helical direction is connected to the inner wall of the second water passage 50A, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the second water passage 50A. That is, there is a gap between the inner edge of the helical blade and the inner wall of the second water passage 50A. Thus, the inner wall of the second water passage 50A provides a connection support for the helical blade.

[0090] In some embodiments, the outlet end of the second water passage 50A is provided with a narrowing section 22. Exemplarily, in some embodiments, the end of the narrowing section 22 forms the outlet end of the second water passage 50A. That is, the fluid of the second water passage 50A is ejected from the end of the narrowing section 22. In other embodiments, the end of the narrowing section 22 is also connected to a constant diameter section and / or an expanding diameter section, which forms the outlet end of the second water passage 50A.

[0091] It should be noted that, along the direction of fluid movement, the flow area of ​​the fluid decreases in the aforementioned narrowing section, remains basically unchanged in the aforementioned constant diameter section, and increases in the aforementioned widening section.

[0092] The narrowing section 22 increases the impact force of the fluid by limiting the flow area when the fluid is ejected, resulting in a greater impact force on the fluid at the outlet of the first water channel 40A and achieving a better mixing effect.

[0093] Meanwhile, the narrowing section 22 gives the outlet of the second water channel 50A a large jet velocity, which can generate a significant negative pressure in a relatively large area. This negative pressure causes the fluid at the outlet of the first water channel 40A to be drawn in and mixed with the fluid in the second water channel 50A, thus improving the mixing and foaming effect.

[0094] In some embodiments, the extension lengths of the constant diameter section and the expanding diameter section along the second water passage 50A are both less than or equal to the extension length of the narrow diameter section 22 along the second water passage 50A. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the constant diameter section and / or the expanding diameter section can reduce the loss of circumferential velocity components and impact force after the fluid flows out of the narrow diameter section 22.

[0095] As an optional embodiment, in the embodiment provided with turbulent flow structure 21 and narrowing section 22, the narrowing section 22 is located downstream of turbulent flow structure 21. After passing through turbulent flow structure 21 and narrowing section 22 in sequence, the fluid is ejected into the clothing processing chamber in a conical shape.

[0096] In this embodiment, the fluid in the first water path 40A is a mixture of laundry detergent or laundry powder, especially laundry powder. Since laundry powder is a powdered detergent, it is more prone to clogging and residue than laundry detergent, which may reduce the reliability of the first water path 40A. If the turbulence structure 21 and the narrowing section 22 are located in the first water path 40A, the above-mentioned problems will be more likely to occur. The fluid in the second water path 50A is water, that is, the second water path 50A is used to transport water from the water source. The turbulence structure 21 and the narrowing section 22 are located in the second water path 50A. The water flows through the second water path 50A and flows out at high speed from the outlet end, impacting the laundry powder mixture at the outlet end of the first water path 40A, fully mixing and generating a large amount of foam. Finally, the fluid with a large amount of foam is sprayed out from the outlet end of the liquid outlet water path 20 in a roughly cone shape.

[0097] In some embodiments, please refer to Figure 2 The detergent dispensing device 100 includes a first pipe 41 and a second pipe 42. One end of the first pipe 41 is connected to a water source, for example, connected to a water inlet valve 90, and the other end of the first pipe 41 is connected to a detergent supply assembly for introducing fluid into the detergent supply assembly. In some specific embodiments, the other end of the first pipe 41 is connected to a detergent dispenser 30 for introducing fluid into the detergent dispenser 30.

[0098] One end of the second pipe 42 is connected to the first drain outlet, and the other end is connected to the liquid outlet water passage 20, for guiding the fluid discharged from the first drain outlet to the liquid outlet water passage 20. In this embodiment, the space in the first pipe 41, the space in the second pipe 42, and a portion of the space in the detergent box 30 together constitute at least a part of the first water passage 40A.

[0099] In some embodiments, please refer to Figure 2The detergent dispensing device 100 includes a third pipe 50, one end of which is connected to a water source, and the third pipe 50 is connected to a liquid outlet water channel 20 to guide water from the water source to the liquid outlet water channel 20. In this embodiment, the space within the third pipe 50 can independently define a second water channel 50A, or the space within the third pipe 50 can define a portion of the second water channel 50A.

[0100] It should be noted that the first pipeline 41 mentioned above can be a single complete pipe or it can be composed of multiple pipe segments connected together; there is no limitation on this.

[0101] The second pipe 42 mentioned above can be a single complete pipe or it can be composed of multiple pipe sections connected together; there is no limitation on this.

[0102] The aforementioned third pipe 50 can be a single, complete pipe or composed of multiple pipe segments connected together; no restrictions are imposed here.

[0103] For example, such as Figure 2 As shown, the third pipe 50 may be integrally disposed on the outside of the detergent box 30; or, a part of the third pipe 50 may be integrated into the shell of the detergent box 30, that is, a part of the shell of the detergent box 30 constitutes part of the third pipe 50; or, the third pipe 50 may be a pipe-like structure that penetrates the detergent box 30.

[0104] For example, please refer to Figure 1 The garment processing equipment also includes a door (not shown), a housing (not shown), and a door seal ring 60 disposed on the front side of the bobbin assembly 10. The bobbin assembly 10 is disposed inside the housing. The housing has an opening communicating with the interior of the bobbin assembly 10, and the door is used to open or close the opening. The door seal ring 60 is used to seal the gap between the bobbin assembly 10 and the opening of the housing. When the door closes the opening, the door seals against the door seal ring 60, thereby forming a communicating space between the door, the door seal ring 60, and the interior of the bobbin assembly 10, which constitutes a garment processing chamber.

[0105] The door seal ring 60 has an installation port, and the water outlet end of the liquid outlet water path 20 passes through the installation port of the door seal ring 60 and extends into the radial inner side of the door seal ring 60. This facilitates the direct delivery of the mixture of the first water path 40A and the second water path 50A into the clothing processing chamber by the water outlet end of the liquid outlet water path 20.

[0106] The aforementioned direct delivery into the garment processing chamber refers to the fact that the mixed liquid discharged from the first water channel 40A and the second water channel 50A by the liquid outlet 20 is directly delivered into the garment processing chamber under the influence of gravity and fluid pressure, without the need for guidance from other structures. In this way, the mixed liquid sprays and wets the clothes, improving their cleaning effect.

[0107] In some embodiments, the water outlet of the liquid outlet channel 20 is tilted towards the rear and lower part of the clothing processing chamber to facilitate the sprayed water to cover the clothing in the clothing processing chamber over a large area.

[0108] In some embodiments, please refer to Figure 2 The garment processing equipment includes a water inlet valve 90, which has a first outlet 90a. A first water path 40A and a second water path 50A are both connected to the first outlet 90a. Water is supplied to the garment processing equipment through the water inlet valve 90. The first water path 40A and the second water path 50A are both connected to the first outlet 90a of the water inlet valve 90, which facilitates the installation of the first water path 40A and the second water path 50A, simplifies the setup of the water inlet valve 90, and saves costs.

[0109] like Figure 2 As shown, the inlet valve 90 also has a second outlet 90b, which can be used to supply water to other pipelines.
