Abstract
Description
Technical Field
[0001] This application relates to the field of laundry technology, and more particularly to a dispensing device and a washing machine. Background Technology
[0002] In related technologies, washing machines are usually equipped with a dispensing device, which includes a movable detergent dispenser. When dispensing detergent, the detergent dispenser can be pulled out first, and the detergent required for washing can be put into the detergent dispenser. Then, water is flushed into the detergent dispenser, and the detergent is flushed from the drain outlet of the detergent dispenser into the drum.
[0003] However, the dispensing device is an integral structure, and because the washing box needs to flush water into the drum, all the components of the dispensing device are located above the drum. The dispensing device is relatively large, which will occupy a lot of space at the top of the washing machine, and thus occupy the installation space of other structures. Ultimately, it may lead to an increase in the size of the machine casing, which goes against users' requirements for increasingly smaller washing machine sizes. Summary of the Invention
[0004] This application provides a dispensing device and a washing machine, which can solve the technical problem that the dispensing device requires a large installation space and cannot be used with small washing machines.
[0005] In a first aspect, embodiments of this application provide a dispensing device for dispensing cleaning liquid into the drum of a washing machine, the dispensing device comprising:

[0011] In some embodiments, the dispensing device includes a unidirectional flow structure located within the mixing chamber and disposed at the outlet of the first interface tube, the unidirectional flow structure being used to allow the detergent to flow unidirectionally from the first interface tube into the mixing chamber.
[0012] In some embodiments, the unidirectional conduction structure includes a mounting base and a cover plate. The mounting base is fixed inside the mixing chamber and is disposed adjacent to the first interface pipe. The cover plate is rotatably mounted on the mounting base and rotates between an open position and a closed position.
[0013] When the cover plate is in the open position, the cover plate is set at an angle to the inner wall surface of the mixing component, and the first interface pipe is opened;

[0016] In some embodiments, the unidirectional conduction structure includes an elastic sheet, which is partially connected to the first interface tube and covers the liquid outlet of the first interface tube.
[0017] When the detergent flows from the first interface tube to the mixing chamber, the detergent drives the elastic sheet away from the first interface tube to open the first interface tube.
[0018] When the liquid flows from the mixing chamber to the first interface tube, the liquid causes the elastic sheet to fit against the outlet of the first interface tube, thereby closing the first interface tube.
[0019] In some embodiments, the unidirectional conduction structure includes a mounting sleeve that is fitted around the periphery of the first interface tube, and the mounting sleeve is provided with a plurality of soft pieces located at the liquid outlet of the first interface tube.
[0020] When the detergent flows from the first interface tube into the mixing chamber, the detergent drives the plurality of soft sheets to move away from each other, thereby opening the first interface tube;
[0021] When the liquid flows from the mixing chamber to the first interface tube, the liquid causes the plurality of soft sheets to move closer to each other to close the first interface tube.
[0022] In some embodiments, the unidirectional conduction structure includes:
[0023] A fixing seat is provided at the liquid outlet of the first interface tube;
[0024] A sealing sheet is disposed on the fixed base and is in contact with the liquid outlet of the first interface tube;
[0025] When the detergent flows from the first interface tube into the mixing chamber, the detergent drives the sealing plate away from the liquid outlet of the first interface tube to open the first interface tube.
[0026] When the water flows from the mixing chamber to the first interface pipe, the water drives the sealing plate to fit against the outlet of the first interface pipe, thereby closing the first interface pipe.
[0027] In some embodiments, the end of the mounting base facing away from the first interface tube is provided with a flow guiding structure, which is used to guide the water flow to the sealing sheet.
[0028] In some embodiments, the unidirectional conduction structure includes a movable element that is movably disposed at the liquid outlet of the first interface tube;
[0029] When the detergent flows from the first interface tube to the mixing chamber, the detergent drives the movable part away from the first interface tube to open the first interface tube;
[0030] When the water flows from the mixing chamber to the first interface pipe, the water drives the movable part to approach the first interface pipe to close the first interface pipe.
[0031] In some embodiments, the unidirectional conduction structure includes a limiting seat disposed at the liquid outlet of the first interface tube. The limiting seat has a limiting cavity that communicates with the first interface tube and the mixing cavity. The movable member is located within the limiting cavity, which restricts the movement of the movable member at the liquid outlet of the first interface tube.
[0032] In some embodiments, the axis of the first interface tube intersects the axis of the second interface tube.
[0033] In some embodiments, the centerline of the third interface tube intersects the centerline of the first interface tube and the centerline of the second interface tube.
[0034] In some embodiments, the water supply component includes an inlet valve that is connected to the second interface pipe via a pipeline and is connected to a water source.
[0035] In some embodiments, the liquid dosing assembly includes a liquid dosing pump connected to the first interface pipe via a pipeline, the liquid dosing pump being used to draw the detergent into the mixing chamber.
[0036] In some embodiments, the liquid outlet assembly includes a delivery pipe, one end of which is connected to the third interface pipe, and the other end of which is connected to the drum of the washing machine.
[0037] Secondly, this application provides a washing machine, which includes a casing, a drum, and a dispensing device as described above. The drum is disposed inside the casing, the dispensing device is disposed inside the casing, and the third interface pipe of the dispensing device is connected to the drum.
[0038] The dispensing device and washing machine based on the embodiments of this application have at least the following beneficial effects:
[0039] By setting up a mixing component with a mixing chamber, and the mixing component including a first interface pipe, a second interface pipe, and a third interface pipe communicating with the mixing chamber, a liquid dispensing component is connected to the first interface pipe to dispense detergent into the mixing chamber, and a water dispensing component is connected to the second interface pipe to dispense water into the mixing chamber, so that the water and detergent can be fully mixed in the mixing chamber to form a cleaning solution. A liquid dispensing component is connected to the third interface pipe to dispense the cleaning solution in the mixing chamber into the drum of the washing machine, realizing automatic detergent dispensing. Therefore, according to the actual installation situation, the mixing component, liquid dispensing component, water dispensing component, and liquid dispensing component can be dispersed around the drum, and the liquid dispensing component, water dispensing component, and liquid dispensing component can be connected to the mixing component through pipes. It is not necessary to set the entire dispensing device on the top of the drum, and the space between other structures can be used to install the liquid dispensing component, water dispensing component, liquid dispensing component, and mixing component separately, which can be used for washing machines with smaller size specifications.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0055] Currently, detergent is typically added to the drum of a washing machine via an automatic dispensing system. The system dispenses detergent into a detergent dispenser, then rinses it with water, which is then flushed into the drum through the dispenser's drain outlet. This automatic dispensing system uses a large detergent dispenser, which is semi-open due to its opening for inserting into the dispenser box. Furthermore, because it needs to flush water into the drum, the detergent dispenser is usually placed above the drum. These factors—large size, lack of sealing, and the limitation of its placement above the drum—make the detergent dispenser unsuitable for smaller washing machines such as countertop and wall-mounted models.
[0056] To resolve the above technical issues, please refer to Figure 1 and Figure 2 This application provides a dispensing device 100 for dispensing cleaning liquid into the drum of a washing machine. The dispensing device 100 includes a mixing component 10, a dispensing component 20, a water dispensing component 30, and a dispensing component 40. The mixing component 10 has a mixing chamber 101 and includes a first interface pipe 102, a second interface pipe 103, and a third interface pipe 104 communicating with the mixing chamber 101. The dispensing component 20 is connected to the first interface pipe 102, allowing it to dispense detergent into the mixing chamber 101. The water dispensing component 30 is connected to the second interface pipe 103, allowing it to dispense water into the mixing chamber 101, where the water and detergent are fully mixed to form a cleaning liquid. The dispensing component 40 is connected to the third interface pipe 104, allowing it to dispense the cleaning liquid from the mixing chamber 101 into the drum of the washing machine, thus achieving automatic detergent dispensing and making it suitable for washing machines with smaller dimensions.
[0057] Optionally, the outer contour shape of the mixing component 10 can be cubic, cylindrical, spherical, etc., and the specific shape of the mixing component 10 is not limited in this embodiment. Taking the outer contour shape of the mixing component 10 as a cubic shape as an example, the mixing component 10 can form a mixing cavity 101 inside, and the mixing component 10 includes a first interface tube 102, a second interface tube 103, and a third interface tube 104. The first interface tube 102, the second interface tube 103, and the third interface tube 104 are respectively connected to different sides of the mixing component 10, so that the first interface tube 102, the second interface tube 103, and the third interface tube 104 are all connected to the mixing cavity 101.
[0058] The detergent dispensing assembly 20 may include a detergent dispensing pump 201, which is connected to the first interface pipe 102 via a pipeline, and the detergent dispensing pump 201 can draw detergent into the mixing chamber 101. It should be noted that the detergent dispensing pump 201 itself may have a cavity for storing detergent, or it may have a separate independent storage compartment containing detergent, and the detergent dispensing pump 201 is connected to the storage compartment via a pipeline.
[0059] The water inlet assembly 30 may include a water inlet valve 301, which is connected to the second interface pipe 103 via a pipeline. By opening the water inlet valve 301, water is introduced into the mixing chamber 101, allowing the water to fully mix with the detergent in the mixing chamber 101 to form a cleaning solution. The water inlet valve 301 may be connected to an external water source to introduce external water into the mixing chamber 101, or it may be connected to a chamber inside the washing machine containing water, allowing the detergent in the mixing chamber 101 to be flushed into the drum by circulating the water inside the washing machine.
[0060] The liquid dispensing assembly 40 may include a delivery pipe 401, one end of which is connected to the third interface pipe 104, and the other end of which is connected to the drum of the washing machine. The cleaning liquid in the mixing chamber 101 can be dispensed into the drum of the washing machine through the delivery pipe 401. Alternatively, the delivery pipe 401 may also be connected to a water pump, which can be turned on to draw the cleaning liquid in the mixing chamber 101 into the drum.
[0061] Therefore, depending on the actual installation situation, the mixing component 10, the liquid dispensing component 20, the water dispensing component 30, and the liquid dispensing component 40 can be dispersed around the drum. The liquid dispensing component 20, the water dispensing component 30, and the liquid dispensing component 40 can be connected to the mixing component 10 through pipelines. It is not necessary to place the entire dispensing device 100 on top of the drum. Moreover, the space between other structures can be used to install the liquid dispensing component 20, the water dispensing component 30, the liquid dispensing component 40, and the mixing component 10 respectively, increasing the space utilization rate and making it suitable for washing machines with smaller size specifications.
[0062] Please see Figure 3 In some embodiments, at least a portion of the first interface tube 102 extends into the mixing chamber 101, such that the outlet of the first interface tube 102 is higher than the inner wall of the mixing chamber 101, thereby preventing water from entering the first interface tube 102. When adding detergent, the detergent can also be better placed into the center of the mixing chamber 101, so that the water and detergent can be mixed more evenly.
[0063] Please see Figure 2 and Figure 3In some embodiments, the dispensing device 100 may further include a one-way flow structure 50, which is located in the mixing chamber 101 and disposed at the outlet of the first interface pipe 102. The one-way flow structure 50 is used to allow detergent to flow unidirectionally from the first interface pipe 102 to the mixing chamber 101, and can prevent water from flowing into the first interface pipe 102.
[0064] Optionally, when the dispensing pump 201 adds detergent to the mixing chamber 101, the detergent can squeeze the one-way conduction structure 50, causing the one-way conduction structure 50 to open the first interface pipe 102, and the detergent flows into the mixing chamber 101. When the water inlet valve 301 is opened, water enters the mixing chamber 101, and the water will impact the one-way conduction structure 50, causing the one-way conduction structure 50 to close the first interface pipe 102. This can prevent water from flowing into the first interface pipe 102, thereby preventing water from contaminating the chamber where the detergent is stored, and also preventing trace amounts of detergent from entering the drum during the rinsing stage of the washing machine.
[0065] Please see Figure 3 In some embodiments, the unidirectional conduction structure 50 may include a mounting base 501 and a cover plate 502. The mounting base 501 is fixed inside the mixing chamber 101 and may be arranged adjacent to the liquid outlet of the first interface pipe 102. The cover plate 502 is rotatably mounted on the mounting base 501, so that the cover plate 502 can switch between an open position and a closed position.
[0066] Specifically, when the cover plate 502 is in the open position, the cover plate 502 is set at an angle to the inner wall surface of the mixing component 10, which can open the liquid outlet of the first interface pipe 102, allowing detergent to flow into the mixing chamber 101 from the first interface pipe 102. When the cover plate 502 is in the closed position, the cover plate 502 and the first interface pipe 102 are set at an angle to the inner wall surface of the mixing component 10, allowing detergent to flow into the mixing chamber 101 from the first interface pipe 102. The outlet of the liquid pipe is fitted together to close the outlet of the first interface pipe 102, so that the liquid cannot flow from the mixing chamber 101 into the first interface pipe 102.
[0067] Optionally, the mounting base 501 is provided with a hinged mounting part, and the cover plate 502 is connected to the mounting base 501 through the hinged mounting part, so that the cover plate 502 can rotate relative to the first interface pipe 102. When the liquid pump 201 adds detergent into the mixing chamber 101, the detergent can squeeze the cover plate 502, driving the cover plate 502 to rotate away from the first interface pipe 102, thereby opening the first interface pipe 102. The detergent can flow into the mixing chamber 101 from the liquid outlet of the first interface pipe 102. When the water inlet valve 301 is opened, the water enters the mixing chamber 101, and the water will impact the cover plate 502, driving the cover plate 502 to rotate towards the first interface pipe 102, so that the cover plate 502 covers the liquid outlet of the first interface pipe 102, thereby closing the first interface pipe 102. Thus, the water cannot flow into the first interface pipe 102, preventing the water from diffusing into the chamber where the detergent is stored through the first interface pipe 102.
[0068] Please see Figure 3 In some embodiments, the side of the cover plate 502 facing away from the first interface pipe 102 may have a flow guiding surface 5021, which can guide the water to flow away from the first interface pipe 102.
[0069] Optionally, the guide surface 5021 can be an inclined surface. The guide surface 5021 is inclined to the axis of the first interface pipe 102, and the guide surface 5021 is also inclined to the axis of the second interface pipe 103. When the water flows into the mixing chamber 101 from the second interface pipe 103 and rushes towards the cover plate 502, the water flow formed by the water comes into contact with the guide surface 5021. The guide surface 5021 guides the water flow to flow away from the first interface pipe 102. Thus, under the reverse force of the water flow, the water can drive the cover plate 502 to rotate towards the first interface pipe 102, so that the cover plate 502 and the first interface pipe 102 fit more tightly.
[0070] Please see Figure 4 In some embodiments, the unidirectional conduction structure 50 may include an elastic sheet 503, which may be partially connected to the first interface tube 102 and cover the liquid outlet of the first interface tube 102. When detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent drives the elastic sheet 503 away from the first interface tube 102, thereby opening the first interface tube 102. When water flows from the mixing chamber 101 to the first interface tube 102, the water drives the elastic sheet 503 to adhere to the first interface tube 102, thereby closing the first interface tube 102.
[0071] Optionally, the shape of the elastic sheet 503 is similar to the shape of the liquid outlet of the first interface tube 102. Taking the liquid outlet as a circle as an example, the elastic sheet 503 can be a circular thin sheet, and the size of the elastic sheet 503 is larger than the size of the liquid outlet. Part of the elastic sheet 503 can be connected to the first interface tube 102, and the elastic sheet 503 can cover the entire liquid outlet of the first interface tube 102. Thus, when the detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent can squeeze the elastic sheet 503 away from the first interface tube 102, and the detergent can flow into the mixing chamber 101 from the gap between the elastic sheet 503 and the first interface tube 102. When the water flows from the mixing chamber 101 to the first interface tube 102, the water can impact the elastic sheet 503, making the elastic sheet 503 fit more tightly with the liquid outlet of the first interface tube 102, thereby preventing the water from flowing into the first interface tube 102.
[0072] It should be noted that in this embodiment, a large elastic sheet 503 can be provided so that one elastic sheet 503 can cover the entire liquid outlet of the first interface tube 102. Alternatively, multiple smaller elastic sheets 503 can be provided, with multiple elastic sheets 503 connected to the first interface tube 102, and multiple elastic sheets 503 together covering the entire liquid outlet of the first interface tube 102. The number of elastic sheets 503 is not limited here.
[0073] Please see Figure 5 In some embodiments, the unidirectional conduction structure 50 may include a mounting sleeve 504, which may be fitted around the periphery of the first interface tube 102. The mounting sleeve 504 is provided with a plurality of soft pieces 5041, which are located at the liquid outlet of the first interface tube 102. When detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent can drive the plurality of soft pieces 5041 away from each other to open the first interface tube 102. When water flows from the mixing chamber 101 to the first interface tube 102, the water can drive the plurality of soft pieces 5041 closer to each other to close the first interface tube 102.
[0074] Optionally, the mounting sleeve 504 can be fitted onto the portion of the first interface tube 102 that extends into the mixing chamber 101, and multiple soft pieces 5041 are arranged sequentially along the circumferential direction of the first interface tube 102, with at least two adjacent soft pieces 5041 having overlapping portions. Thus, when the liquid flows from the mixing chamber 101 to the first interface tube 102, the multiple soft pieces 5041 approach each other and completely cover the outlet of the first interface tube 102, preventing the liquid from flowing into the first interface tube 102. When the detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent can be squeezed into the mixing chamber 101 through the gap between two adjacent soft pieces 5041.
[0075] Please see Figure 6 and Figure 7 In some embodiments, the unidirectional conduction structure 50 may further include a fixing seat 505 and a sealing plate 506. The fixing seat 505 may be disposed at the liquid outlet of the first interface tube 102, and the sealing plate 506 may be disposed on the fixing seat 505 and in contact with the liquid outlet of the first interface tube 102. When detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent can drive the sealing plate 506 away from the liquid outlet of the first interface tube 102 to open the first interface tube 102. When water flows from the mixing chamber 101 to the first interface tube 102, the water can drive the sealing plate 506 to adhere to the liquid outlet of the first interface tube 102 to close the first interface tube 102.
[0076] Optionally, the fixing base 505 may include a fixing rod and a plurality of connecting rods. The plurality of connecting rods may be spaced apart circumferentially along the fixing rod, and the plurality of connecting rods are connected to the inner wall of the first interface tube 102, such that the fixing rod is positioned at the middle of the first interface tube 102, and the fixing rod extends at least partially out of the first interface tube 102. The sealing sheet 506 may be sleeved on the fixing rod, such that the sealing sheet 506 may cover and contact the liquid outlet of the first interface tube 102. More specifically, the first interface tube 102 has a contact surface that forms the liquid outlet, and the contact surface is intersected with the axis of the first interface tube 102. The sealing sheet 506 may contact the contact surface, such that the sealing sheet 506 may cover the liquid outlet of the first interface tube 102.
[0077] When detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent can drive the sealing plate 506 away from the contact surface to open the first interface tube 102, so that the detergent can enter the mixing chamber 101 through the gap between the sealing plate 506 and the contact surface. When water flows from the mixing chamber 101 to the first interface tube 102, the water can impact the sealing plate 506, so that the sealing plate 506 adheres to the contact surface, thereby closing the first interface tube 102 and preventing water from flowing into the first interface tube 102.
[0078] Please see Figure 6 In some embodiments, the end of the fixed base 505 facing away from the first interface tube 102 is provided with a flow guiding structure 5051, which can guide the water to flow to the sealing sheet 506.
[0079] Optionally, the fixing base 505 includes a fixing rod, and the part of the fixing rod extending out of the first interface tube 102 can be provided with a flow guiding structure 5051. The flow guiding structure 5051 can be a hemispherical structure, and the flow guiding arc surface on the flow guiding structure 5051 can guide the water to flow to the sealing sheet 506, so that the sealing sheet 506 fits more tightly with the liquid outlet of the first interface tube 102.
[0080] More specifically, the flow guiding structure 5051 can guide the water flow formed by the water to the part where the sealing sheet 506 overlaps with the contact surface, so that the sealing sheet 506 and the contact surface fit more tightly, preventing water from flowing into the first interface pipe 102 from between the sealing sheet 506 and the contact surface.
[0081] Please see Figure 8 In some embodiments, the unidirectional conduction structure 50 may include a movable member 507, which is movably disposed at the liquid outlet of the first interface tube 102. When detergent flows from the first interface tube 102 to the mixing chamber 101, the detergent can drive the movable member 507 away from the first interface tube 102 to open the first interface tube 102. When water flows from the mixing chamber 101 to the first interface tube 102, the water can drive the movable member 507 closer to the first interface tube 102 to close the first interface tube 102.
[0082] Optionally, the movable member 507 can be a piston-like structure, and the movable member 507 can move axially relative to the first interface pipe 102 along the first interface pipe 102. When the detergent flows from the first interface pipe 102 to the mixing chamber 101, the detergent can squeeze the movable member 507, driving the movable member 507 away from the first interface pipe 102, so that the detergent can flow into the mixing chamber 101 from the liquid outlet of the first interface pipe 102. When the water flows from the mixing chamber 101 to the first interface pipe 102, the water flow formed by the water can impact the movable member 507, driving the movable member 507 closer to the first interface pipe 102, thereby closing the first interface pipe 102 and preventing the water from entering the first interface pipe 102.
[0083] Please see Figure 8 In some embodiments, the unidirectional conduction structure 50 may further include a limiting seat 508, which is fixedly disposed at the liquid outlet of the first interface tube 102. The limiting seat 508 may be provided with a limiting cavity 5081, which can communicate with the first interface tube 102 and the mixing cavity 101. The movable member 507 is located in the limiting cavity 5081, and the limiting cavity 5081 can restrict the movement of the movable member 507 at the liquid outlet of the first interface tube 102.
[0084] Optionally, the limiting seat 508 may include a base and a top cover. The base is fixed to the liquid outlet of the first interface tube 102, and the top cover is disposed on the top of the base. The base and the top cover together define the limiting cavity 5081. The bottom surface of the base is provided with a through hole communicating with the first interface tube 102. The side wall of the base may also be provided with a through hole communicating with the mixing cavity 101, and the top cover may also be provided with a through hole communicating with the mixing cavity 101. The first interface tube 102 can communicate with the mixing cavity 101 through the limiting cavity 5081. The movable member 507 can be disposed in the limiting cavity 5081. Thus, under the limiting action of the limiting cavity 5081, the movable member 507 is restricted to move at the liquid outlet of the first interface tube 102, so that the movable member 507 can better open or close the first interface tube 102.
[0085] In some embodiments, the movable member 507 has a spherical structure, and a groove adapted to the movable member 507 is provided at the liquid outlet of the first interface pipe 102. When water impacts the movable member 507, the movable member 507 can fit more tightly with the liquid outlet, increasing the sealing performance between the movable member 507 and the liquid outlet. Of course, the movable member 507 can also be a cylindrical plug or other piston structure; the shape of the movable member 507 is not limited here.
[0086] Please see Figures 9 to 11 In some embodiments, the axis of the first interface tube 102 can intersect with the axis of the second interface tube 103.
[0087] Optionally, the axis of the first interface pipe 102 is perpendicular to the axis of the second interface pipe 103. When the water inlet valve 301 is opened and water is added into the mixing chamber 101, the water flow formed by the water first flows to the wall of the mixing chamber 101. After the water flow changes direction at the wall, it flows to the first interface pipe 102. This can prevent the water flow from flowing into the mixing chamber 101 from the second interface pipe 103 and directly rushing towards the first interface pipe 102, thus preventing the impact force of the water flow from being too large and causing some water to flow into the first interface pipe 102.
[0088] Please see Figures 9 to 11 In some embodiments, the axis of the third interface tube 104 intersects the axis of the first interface tube 102 and the axis of the second interface tube 103.
[0089] Optionally, the centerline of the first interface tube 102 and the centerline of the second interface tube 103 are coplanar, and the centerline of the third interface tube 104 can intersect the plane. Preferably, the centerline of the third interface tube 104 is perpendicular to the centerline of the first interface tube 102, and the centerline of the third interface tube 104 is perpendicular to the centerline of the second interface tube 103.
[0090] When the dispensing pump 201 dispenses detergent into the mixing chamber 101, the detergent flows towards the wall of the mixing chamber 101, ensuring that the detergent remains within the mixing chamber 101. This prevents the detergent from being directly dispensed into the third interface pipe 104. Furthermore, when the water inlet valve 301 is opened to dispense water into the mixing chamber 101, the water flow is prevented from flowing directly into the third interface pipe 104. Instead, the water flow is allowed to circulate within the mixing chamber 101 and mix thoroughly with the detergent before flowing into the third interface pipe 104, resulting in a more uniform mixing of the water and detergent within the mixing chamber 101.
[0091] This application also proposes a washing machine, which includes a dispensing device 100, a casing, and a drum as described above. The drum can be disposed inside the casing, the dispensing device 100 can be disposed around the drum, and the third interface pipe 104 of the dispensing device 100 can communicate with the drum.
[0092] The beneficial effects of the washing machine in this application are the same as those of the dispensing device 100 in this application, and will not be described again here.
