Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a liquid storage box sealing cap assembly, a liquid storage box, and a washing device. Background Technology

[0002] With the development of science and technology, intelligent detergent dispensing technology is increasingly being applied to the operation of washing machines. This technology can precisely add detergent based on the amount of laundry, largely avoiding inaccurate dosages caused by manual detergent dispensing. Furthermore, intelligent detergent dispensing technology allows for the addition of a larger volume of detergent at once, providing a long-lasting solution and significantly reducing the time and cost associated with dispensing detergent for each wash.

[0003] The intelligent dispensing system of existing high-end garment processing devices is installed inside the overall structure and cannot be disassembled. This makes it impossible to clean the detergent dispenser, and when different detergents are mixed, it is easy to produce odors.

[0004] Some garment processing devices have removable detergent dispensers that can be cleaned. These dispensers are usually directly connected to the water inlet and act as part of the water inlet path. However, when adding detergent, the dispensing port does not have a sufficient sealing structure, which can easily lead to the risk of detergent leakage or water from the water inlet path spreading into the storage chamber, causing various problems.

[0005] A small number of laundry detergent dispensers have a sealed detergent box, but the sealing structure is a simple "O" type, which is prone to failure and has poor sealing effect. Summary of the Invention

[0006] In view of this, the present invention provides a liquid storage box sealing cap assembly, a liquid storage box, and a washing device, which at least solves the technical problem of poor sealing effect at the liquid filling port of the liquid storage box in the prior art, specifically:

[0016] An outer ring is disposed radially outside the inner ring, and the outer ring and the inner ring are connected along the entire circumference;

[0017] On the axial first end face of the sealing ring, an annular groove is formed between the inner ring and the outer ring, and the first end face of the sealing ring is attached to the cover to form the sealing cavity.

[0018] Optionally, a support ring is provided on the inner ring, and the support ring is connected to the axial second end face of the inner ring.

[0019] When the sealing ring is in the installed state, the support ring is located outside the mounting groove and fits against the outer peripheral wall of the protrusion.

[0020] Alternatively, the outer peripheral wall of the outer ring forms a side sealing surface, and the axial second end face of the outer ring constitutes an end sealing surface.

[0021] A raised ring structure is formed circumferentially on the side sealing surface and / or the end sealing surface.

[0022] Further optionally, a plurality of the convex ring structures are provided on the side sealing surface and / or the end sealing surface.

[0023] Alternatively, the sidewall of the protrusion may be provided with a locking claw, which is used to engage with the injection port.

[0024] Alternatively, a recessed handle may be formed on one side of the cover opposite to the protrusion.

[0025] Secondly, the present invention provides a liquid storage box, including a box body, wherein a liquid injection port is provided on the box body, and the liquid storage box sealing cap assembly is disposed at the liquid injection port for sealing the liquid injection port.

[0026] Alternatively, the box body is further provided with a one-way air inlet, which allows air to flow into the box body when the air pressure inside the box body is low.

[0027] Alternatively, the liquid storage box has at least two independent liquid storage chambers inside, and each liquid storage chamber is provided with a corresponding liquid injection port.

[0028] Alternatively, a valve is provided at the liquid outlet of the container, the valve being used to block the liquid outlet when the liquid storage container is not in the installed state.

[0029] Further optionally, it also includes a rear cover, which snaps onto the rear side panel of the housing.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0056] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0057] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides a liquid storage box sealing cap assembly for sealing the liquid filling port 101 of the liquid storage box, including a sealing cap 11 and a sealing ring 12. The sealing cap 11 is detachably fitted onto the liquid filling port 101, and the sealing ring 12 is disposed between the sealing cap 11 and the liquid filling port 101; wherein,

[0059] The sealing cover 11 is provided with a sealing ring mounting portion 113, and the sealing ring 12 is installed in the sealing ring mounting portion 113. A portion of the sealing ring 12 is attached to the sealing cover 11, and a sealing cavity is formed between the sealing ring 12 and the sealing cover 11; or...

[0060] The inner wall of the injection port 101 is provided with a sealing ring mounting part 113. The sealing ring 12 is installed in the sealing ring mounting part 113. A part of the sealing ring 12 is attached to the inner wall of the injection port 101, and a sealing cavity is formed between the sealing ring 12 and the inner wall of the injection port 101.

[0061] In one specific embodiment, such as Figure 3 , Figure 4 As shown, the sealing cap is constructed as a circular cap, including;

[0062] The cover 111 is a circular structure with an outer diameter larger than the inner diameter of the injection port, and is used to abut against the outside of the injection port.

[0063] The protrusion 112 protrudes towards one side of the cover 111 and is used to extend into the injection port. Preferably, the protrusion 112 is constructed as a protrusion with a certain taper, and its size gradually decreases in the direction away from the cover 111 to facilitate its extension into the injection port. Furthermore, the protrusion 112 is collinear with the axis of the cover 111.

[0064] A mounting groove is formed circumferentially on the side wall of the protrusion 112, which constitutes the sealing ring mounting part 113 for mounting the sealing ring. Preferably, the cover 111 forms part of the inner wall of the mounting groove, so that the sealing ring can contact the cover 111 after installation.

[0065] Preferably, a claw 114 is also provided on the side wall of the protrusion 112, the claw 114 being used to engage with the injection port. Two claws 114 are arranged opposite each other, extending in opposite directions along the radial direction of the protrusion 112, for engaging with the edge of the injection port. Correspondingly, the inner edge of the injection port has a notch corresponding to the claw 114, allowing the claw 114 to pass through. The claw 114 extends into the inside of the injection port, and then the cover 111 is rotated to engage the claw 114 with the inner edge of the injection port. It is conceivable that to increase the load-bearing capacity of the engagement, more claws 114 can be provided, for example, three or four.

[0066] Preferably, a recessed handle 115 is formed on one side of the cover 111 opposite to the protrusion 112. When the cover 111 is installed or removed, the handle 115 makes it convenient for the user to grab and rotate it.

[0067] like Figure 5 , Figure 6 As shown, the sealing ring includes:

[0068] The inner ring 121 is used to be embedded into the sealing ring mounting part 113 to complete the installation of the sealing ring;

[0069] An outer ring 122 is arranged radially outside the inner ring 121, and the outer ring 122 and the inner ring 121 are connected along the entire circumference;

[0070] On the first axial end face of the sealing ring, an annular groove 123 is formed between the inner ring 121 and the outer ring 122. The first end face of the sealing ring is attached to the cover 111 to form the sealing cavity. When the sealing cover presses the sealing ring, the air in the sealing cavity is squeezed out of the sealing cavity, forming a vacuum-like state, which allows the sealing ring to adhere to the cover 111 and further improves the sealing performance between the sealing ring and the cover 111.

[0071] Preferably, a support ring 124 is provided on the inner ring 121. The support ring 124 is connected to the axial second end face of the inner ring 121, providing support and ensuring that the sealing ring as a whole has a certain structural strength, preventing excessive deformation that could lead to misalignment and loss of sealing during assembly. When the sealing ring is installed, the support ring 124 is located outside the mounting groove and fits against the outer peripheral wall of the protrusion 112, providing both support and sealing.

[0072] The outer peripheral wall of the outer ring 122 forms a side sealing surface, and the axial second end face of the outer ring 122 forms an end sealing surface. A convex ring structure 125 is formed circumferentially on the side sealing surface and / or the end sealing surface. In this embodiment, one convex ring structure 125 is formed on the side sealing surface, and two convex ring structures 125 are formed on the end sealing surface. The convex ring structures 125 can improve the sealing performance of the sealing ring.

[0073] Another approach is to install a sealing ring mounting part 113 at the injection port. The sealing ring can be fixedly installed inside the injection port, which can also play a sealing role.

[0074] The sealing ring in the liquid storage box sealing cover assembly provided by the present invention forms a sealing fit with multiple parts of the sealing cover and the liquid injection port, thereby ensuring the reliability of the seal and improving the strength of the sealing ring itself.

[0075] like Figure 1 , Figure 2 As shown, the present invention provides a liquid storage box 1, comprising:

[0076] The box body 10 is provided with a liquid inlet 101 and a liquid outlet 102. A sealing cap 11 is provided on the liquid inlet 101 and a valve is provided at the liquid outlet 102. The valve is used to block the liquid outlet 102 when the liquid storage box 1 is not in the installation state.

[0077] A first liquid level detection device 19 is provided on the box body 10. The first liquid level detection device 19 is located near the liquid outlet 102 and is used to detect the liquid level in the box body 10.

[0078] It also includes an electrical connection part 14 disposed on the outer wall of the housing 10. The electrical connection part 14 is electrically connected to the first liquid level detection device 19. When the housing 10 is in the installation state, the electrical connection part 14 is used to abut against the external device to form a detection circuit. Preferably, the electrical connection part 14 is electrically connected by contact conduction, for example, it is constructed as an elastic conductive sheet or a conductive post.

[0079] The box body 10 has an internal cavity for holding detergent. In this embodiment, the box body 10 is constructed as a narrow and elongated structure, with an injection port 101 formed on the upper part of its side wall. An openable sealing cap 11 is provided at the injection port 101, and a sealing ring 12 is provided on the sealing cap 11. The sealing cap 11 is preferably connected to the injection port 101 by a rotational snap-fit ​​method to seal the injection port 101, or the injection port 101 can be opened to inject detergent into the box body 10. In this embodiment, the injection port 101 is formed on the side wall (i.e., the surface with the largest area), so that the box body 10 will not tip over when detergent is added into it. The opening of the injection port 101 can also be made larger, making it more convenient to add detergent.

[0080] Preferably, the outlet 102 is located on the rear side panel of the box body 10, at the bottom of the rear side panel. The first liquid level detection device 19 is located above the outlet 102 or flush with the outlet 102, and is used to detect the liquid level. In this application, the rear side panel of the box body 10 is the innermost panel when installed. A guide plate is provided on the lower side inside the box body 10. The guide plate is inclined towards the location of the outlet 102 to form a guide surface, so that the detergent can flow to the outlet 102 by itself. The first liquid level detection device 19 is preferably a liquid level probe. A first mounting hole is provided on the rear side panel of the box body 10. The first liquid level detection device 19 is installed into the first mounting hole, partially extending into the inside of the box body 10, and sealing the first mounting hole.

[0081] Preferably, the housing 10 forms multiple independent cavities, each cavity being provided with an injection port 101, an outlet, and a first liquid level detection device 19. Two cavities can be used to store different types of detergents, such as one for storing detergent liquid and the other for storing fabric softener.

[0082] The housing 10 is also equipped with a one-way air inlet, which allows air to flow into the housing 10 when the internal air pressure is low. The air inlet is preferably located on the side wall of the housing 10, for example, opposite the liquid inlet 101. Figure 7 As shown, the one-way air inlet includes a through hole communicating with the inner cavity of the box 10 and a one-way ventilation structure 13. The one-way ventilation structure 13 is snapped into the through hole and includes a sealing part formed inside the box 10. The sealing part is made of a flexible material. When the air pressure inside and outside the box 10 is the same, the sealing part seals the through hole. When the air pressure inside the box 10 decreases due to the reduction of detergent, the sealing part can deform under the action of external air pressure, allowing air to enter the box 10. Preferably, in other embodiments, the one-way ventilation structure 13 can also be replaced by other forms of one-way valve structures.

[0083] Preferably, it also includes a rear cover 15, which is fastened to the rear side panel of the box body 10. The rear cover 15 is provided with an outlet corresponding to the liquid outlet 102. A valve is provided on the rear cover 15 and connected to the outlet. When the rear cover 15 is fastened to the rear side panel, the valve extends into the liquid outlet 102.

[0084] The valve is preferably a needle valve, comprising a valve seat 161 disposed at the outlet on the rear cover 15, a valve body 162 movably disposed within the valve seat 161, a needle valve spring providing elastic support for the valve body 162, and a needle valve plug 163 confining the valve body 162 and the needle valve spring within the valve seat 161. The valve body 162 has a sealing structure. In its natural state, the needle valve spring pushes the valve body 162 against the valve port, sealing the valve port and preventing detergent from flowing out of the housing 10. When the valve body 162 is pushed inward, the needle valve spring compresses, and the valve body 162 moves and separates from the valve port. The side of the valve body 162 has a perforated structure, through which the valve port communicates with the inner cavity of the housing 10, allowing detergent to flow out.

[0085] Preferably, the rear cover 15 is also provided with positioning holes 152 for the installation and positioning of the liquid storage box 1. Further, multiple positioning holes 152 are provided; in this embodiment, two are provided to improve positioning accuracy. The rear cover 15 is also provided with a snap-fit ​​structure for the fixed installation of the liquid storage box 1.

[0086] An electrical connection portion 14 is disposed between the rear side plate and the rear cover 15, and is electrically connected to the first liquid level detection device 19 via a wire. The electrical connection portion 14 is positioned between the rear side plate and the rear cover 15 to separate it from the interior of the housing 10, and is not completely exposed under the action of the rear cover 15, thus providing some protection. An electrical connection hole 151 is formed on the rear cover 15, allowing at least a partial exposure of the electrical connection portion 14. The electrical connection hole 151 is a through hole formed on the rear cover 15, enabling the electrical connection structure to contact the electrical contact piece 14 through the electrical connection hole 151.

[0087] A magnet 17 is provided between the rear cover 15 and the rear side panel. The magnet 17 is used to cooperate with the detection component of the washing box installation position for installation detection, such as cooperating with the Hall sensor to detect whether the liquid storage box 1 is installed in place.

[0088] Preferably, a handle 104 is provided at the front end of the box body 10 for the operator to grip. The handle 104 can be formed by a concave structure near the front end of the box body 10, or it can be constructed as a through hole penetrating the box body 10. Preferably, the handle 104 should not be too large to reduce the space occupied in the inner cavity of the box body 10. Furthermore, a decorative panel 105 is also provided at the front end of the box body 10 to make the box body 10 more aesthetically pleasing after installation.

[0089] Preferably, in this embodiment, the liquid storage box 1 is a detergent box, used for storing detergent, fabric softener, etc. in the washing machine.

[0090] The present invention also provides a detergent dispenser assembly, such as Figure 8 , Figure 14As shown, the device includes the aforementioned liquid storage box 1 and detergent box mounting box 2. The liquid storage box 1 is detachably installed into the detergent box mounting box 2. The detergent box mounting box 2 has a receiving cavity for accommodating the liquid storage box 1. The detergent box is installed into the receiving cavity in the detergent box mounting box 2.

[0091] like Figure 9 As shown, the detergent box 2 preferably includes a first housing 201 and a second housing 202. The first housing 201 and the second housing 202 form a housing structure with one end open. The liquid storage box 1 is installed inside the housing structure and can be protected by the housing.

[0092] The detergent dispenser mounting box 2 is equipped with a locking structure 27 located on the back of the detergent dispenser mounting box 2. The locking structure 27 engages with a snap-fit ​​structure on the rear cover 15 of the liquid storage box 1 to secure the liquid storage box 1. When the liquid storage box 1 is pushed into the detergent dispenser mounting box 2 and the locking structure 27 is pressed, the locking structure 27 engages with the snap-fit ​​structure, fixing the liquid storage box 1 inside the detergent dispenser mounting box 2. Pushing the liquid storage box 1 again separates the locking structure 27 from the snap-fit ​​structure, allowing the liquid storage box 1 to be removed.

[0093] Preferably, in another embodiment, a retractable locking structure 18 can be provided at the front end of the liquid storage box 1, and correspondingly, a slot is provided at the opening of the detergent box mounting box 2. A button is provided at the front end of the box body 10, and the locking structure includes a one-way retractable latch. Pressing the button can control the retractable latch to retract, thereby controlling its separation or engagement with the slot.

[0094] The detergent dispenser housing 2 also includes a spring-loaded structure 24, such as Figure 15 As shown, the spring-loaded structure 24 is located on the back of the detergent dispenser housing 2. When the snap-fit ​​structure releases the liquid storage box 1, the spring-loaded structure 24 pushes the liquid storage box 1 outwards from the detergent dispenser housing 2. The spring-loaded structure 24 includes a fixed base 242 with a barrel-shaped mounting cavity, a push rod 241, and an elastic element 243. The elastic element 243 is located inside the mounting cavity. One end of the push rod 241 extends into the mounting cavity and presses against the elastic element 243. The fixed base 242 is mounted onto the housing 2. The housing 2 has a limiting hole. Through the limiting hole, one end of the push rod 241 extends into the housing 2. Correspondingly, a limiting protrusion 2412 is formed at the second end of the push rod. The radial dimension of the limiting protrusion 2412 is larger than the radial dimension of the limiting hole. Under the limiting action of the limiting hole and the limiting protrusion 2412, it cannot completely slide out of the mounting cavity.

[0095] A guide structure is also provided between the push rod 241 and the cavity to allow the push rod 241 to move smoothly along the axial direction. Preferably, the guide structure includes a guide rib 2411 formed along the length of the push rod 241 and disposed on the push rod 241. The guide rib 2411 is a rib plate structure. Correspondingly, a guide groove is provided in the mounting cavity, and the guide rib 2411 is slidably disposed in the guide groove to form a sliding fit, guiding the sliding of the push rod 241.

[0096] When the liquid storage box 1 is pushed into the detergent box installation box 2, the push rod 241 is pushed to move the push rod 241 into the cavity. When the locking structure separates from the buckle structure, the push rod 241 pushes the liquid storage box 1 to move outward a certain distance, making it easy to remove the liquid storage box 1.

[0097] like Figure 9 , Figure 10 As shown, the detergent box 2 is equipped with a mixing box 23. The mixing box 23 includes a mixing chamber, and an inlet 231, an outlet 232, and a detergent inlet 233 connected to the mixing chamber. The inlet 231 is connected to the washing water supply pipe, and the outlet 232 is connected to the washing water outlet pipe. The detergent inlet 233 is connected to the outlet of the storage box 1. The mixing box 23 is used to mix the washing water and detergent before they flow out. Preferably, there are two detergent inlets 233, corresponding to the two outlets 232 on the storage box 1.

[0098] The mixing box 23 is installed on the back of the storage box 1. Preferably, a locking mounting base 236 is provided on the mixing box 23, and the locking structure is provided on the locking mounting base 236, so that the locking structure and the mixing box 23 can be installed at the same time.

[0099] Preferably, the mixing box 23 is provided with a positioning post 235, which cooperates with the positioning hole 152 on the rear cover 15 of the storage box 1 for positioning. In this embodiment, two positioning posts 235 and two positioning holes 152 are provided to position the installation of the storage box 1.

[0100] like Figure 9 , Figure 11As shown, the system also includes a pump 3. The inlet end 31 of the pump 3 is connected to the outlet 232 of the storage box 1, and the outlet end 32 of the pump 3 is connected to the detergent inlet 233 of the mixing box 23. The pump 3 is used to pump detergent from the storage box 1 into the mixing box 23. Correspondingly, when the mixing box 23 is provided with two detergent inlets 233, the pump 3 is provided with two inlet ends 31 and an outlet end 32. Preferably, the mixing box 23 is also provided with a clearance hole 237, through which the inlet end 31 of the pump 3 can pass through the clearance hole 237 and extend into the outlet 232 of the storage box 1 to push the valve body 162 of the needle valve to open it. The clearance hole 237 facilitates the installation of the pump 3, allowing the pump 3 and the mixing box 23 to be installed together, saving installation space. Preferably, a mounting bracket 28 is provided on the detergent box mounting box 2 for fixing the pump 3.

[0101] Preferably, the pump 3 is equipped with a second liquid level detection device 33, which is connected to the inner cavity of the pump 3. The second liquid level detection device 33 is preferably a liquid level probe. The second liquid level detection device 33 is connected to the first liquid level detection device 19, and the two together detect the liquid level in the storage box 1. The first liquid level detection device 19 and the second liquid level detection device 33 form a path and jointly output a signal to detect the liquid level in the storage box 1.

[0102] A conductive spring 25 is provided on the rear side of the detergent dispenser mounting box 2. When the liquid storage box 1 is installed, the conductive spring 25 abuts against the electrical connection part 14. The detergent dispenser mounting box 2 is also provided with a fixing cover 26, and the conductive spring is disposed on the fixing cover 26. Preferably, the fixing cover 26 is integrated with the mixing box 23 for easy installation.

[0103] The detergent dispenser mounting box 2 is also equipped with a sensor, which works in conjunction with the magnet 17 to detect whether the liquid storage box 1 is installed correctly. The sensor is preferably a Hall effect sensor, located on the back of the detergent dispenser mounting box 2.

[0104] The detergent dispenser mounting box 2 has guide structures at its bottom and / or top to guide the assembly of the liquid storage box 1. Specifically, guide grooves are provided on the upper and lower outer side walls of the liquid storage box 1, and correspondingly, guide parts that cooperate with the guide grooves are provided on the detergent dispenser mounting box 2 to guide the assembly and disassembly of the liquid storage box 1. Preferably, multiple rollers 291 are provided at the bottom of the detergent dispenser mounting box 2, distributed along the installation direction of the liquid storage box 1. The rollers 291 are used to contact the guide grooves, and the rolling of the rollers 291 reduces friction during the sliding of the liquid storage box 1, making the sliding of the liquid storage box 1 smoother.

[0105] Preferably, a roller bracket 29 is provided at the bottom of the detergent box mounting box 2, and multiple rollers 291 are assembled on the roller bracket 29. The roller bracket 29 is then snapped into the bottom of the detergent box mounting box 2 as the bottom wall of the detergent box mounting box 2, providing support for the liquid storage box 1. This facilitates the assembly of the rollers 291 and subsequent maintenance. Furthermore, rollers 291 can be provided at both the top and bottom of the liquid storage box 1, with the upper and lower rollers 291 cooperating with the guide grooves to prevent the liquid storage box 1 from shaking during installation and improve assembly accuracy.

[0106] Furthermore, an elastic positioning structure is provided on the top of the detergent box 2 to position the liquid storage box 1 during installation or disassembly. In this embodiment, as... Figure 9 , Figure 12 , Figure 13 As shown, the elastic positioning structure includes a pressure roller structure 21, comprising a pressure roller mounting base, a spring, and a pressure roller. Correspondingly, a limiting groove 106 is provided on the liquid storage box 1. When the liquid storage box 1 is in a preset position, the pressure roller rolls into the limiting groove 106, providing a certain resistance to the sliding of the liquid storage box 1. When the liquid storage box 1 is installed in place, the limiting groove 106 is offset from the pressure roller, and the limiting groove 106 is located closer to the inside. Thus, when the liquid storage box 1 is ejected, after sliding outward a certain distance, the pressure roller enters the limiting groove 106, preventing the liquid storage box 1 from continuing to slide outward, thereby preventing the liquid storage box 1 from sliding out on its own and falling. When the liquid storage box 1 is pulled forcefully again, the pressure roller compresses the spring and contracts, the pressure roller rolls out of the limiting groove 106, and the liquid storage box 1 can continue to slide.

[0107] The front end of the detergent box 2 is provided with a mounting base cover 203 and a mounting base trim panel 204 to improve the strength and aesthetics of the detergent box 2.

[0108] The detergent dispenser assembly provided by this invention is suitable for clothing processing equipment such as washing machines, shoe washing machines, or dishwashers.

[0109] The present invention also provides a washing device, preferably a washing machine, including the aforementioned detergent dispenser assembly. Preferably, the washing machine includes multiple washing drums arranged vertically, with the detergent dispenser assembly disposed on the side of the uppermost washing drum. In this embodiment, the washing machine includes a first washing drum, a second washing drum, and a third washing drum arranged sequentially from top to bottom. The detergent dispenser assembly is disposed on the side of the first washing drum and is used to supply detergent to the three washing drums. The placement of the detergent dispenser assembly at the top reduces the impact of the pump body on the accumulation of liquid in the pipes during the delivery process, while also reducing the technical requirements for the pump body and reasonably reducing costs.

[0110] This invention facilitates the assembly and disassembly of the detergent dispenser, and the dispenser is detachable for easy cleaning. Furthermore, the guiding and positioning structure between the detergent dispenser and the detergent dispenser mounting box 2 improves the installation accuracy of the detergent dispenser, ensuring a reliable detergent supply and enhancing the user experience.
