Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a mixing box, dispensing device, and cleaning equipment for a cleaning device. Background Technology

[0002] Washing machines are widely used as common household appliances. A washing machine consists of a washing tub and a mixing tank for adding detergent and water.

[0003] In related technologies, a mixing tank generally includes a mixing tank body, a storage tank, and a dispensing pipe. The storage tank is removable and placed inside the mixing tank body, providing detergent to the mixing tank body. The mixing tank body is not only connected to a water source but also connected to a washing tank via the dispensing pipe. With this configuration, after water and detergent enter the mixing tank body, they undergo simple pre-mixing within the mixing tank body to form a mixture, which then flows into the washing tank through the dispensing pipe.

[0004] However, the mixture tends to flow around inside the mixing box, inevitably flowing to unwanted locations within the box. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a mixing box, dispensing device, and cleaning equipment for cleaning devices, used to prevent the mixture formed by water and detergent from flowing into unwanted locations within the mixing box body.

[0006] This application is achieved through the following technical solution.

[0007] This application provides a mixing chamber for a cleaning device, including a cover assembly, a mixing chamber body, a blocking member, and a guide member. The cover assembly has a first inlet and a second inlet. The cover assembly is fastened to the opening of the mixing chamber body, which has a first outlet and a second outlet. The first outlet is for connecting to a premixing device, and the second outlet is for connecting to the washing tub of the cleaning device. The blocking member is disposed within the mixing chamber body and is arranged around the first outlet to form a converging chamber. The first inlet is for connecting a water source and the converging chamber, and the second inlet is for connecting a laundry detergent and the converging chamber. The second outlet is located outside the converging chamber, and the blocking member has a drain outlet connecting to the converging chamber. The guide member is disposed within the mixing chamber body, extending from the drain outlet to the second outlet and forming a guide channel connecting the second outlet and the drain outlet.

[0008] In the technical solution of this application embodiment, the cover assembly is fastened to the opening of the mixing box body. External water can be introduced into the gathering chamber inside the mixing box body through the first inlet, while the laundry detergent can be introduced into the gathering chamber inside the mixing box body through the second inlet. In the gathering chamber, the laundry detergent and water undergo simple pre-mixing to form a mixture. The mixture is then discharged into the washing tub through the first outlet, thereby achieving the washing of clothes in the washing tub. Since the blocking member has a drain outlet, the mixture that is not discharged through the first outlet in time will enter the guide channel through the drain outlet and then flow to the second outlet, and be discharged into the washing tub from the second outlet.

[0009] By setting up the blocking and guiding components, the mixed liquid can enter the collecting chamber as much as possible, and then enter the premixing device through the first outlet to achieve the mixing of water and laundry detergent, thereby improving the cleaning effect on clothes. The excess liquid can be discharged into the washing tub through the guide channel and the second outlet under the guidance of the guiding components, thus preventing the mixed liquid from flowing to unwanted positions in the mixing box body.

[0010] In some embodiments of this application, the mixing box body includes a connected bottom wall and a peripheral wall, the peripheral wall being disposed circumferentially along the bottom wall to form a box opening opposite to the bottom wall, and a second outlet located on the bottom wall. A blocking member is located between the cover assembly and the bottom wall, and extends from the bottom wall toward the cover assembly to form a converging chamber with a first opening at the top, the first inlet and the second inlet both facing the first opening; the first outlet is located on the portion of the bottom wall opposite to the first opening.

[0011] With this configuration, a converging chamber with a first opening at the top can be formed on the bottom wall. Since both the first inlet and the second inlet face the first opening of the converging chamber, water and laundry detergent can enter the converging chamber through the first opening.

[0012] In some embodiments of this application, along the circumferential direction of the first outlet, the blocking member includes a first baffle and a second baffle arranged sequentially, the first end of the first baffle is adjacent to and connected to the first end of the second baffle, and the second end of the first baffle is adjacent to and spaced apart from the second end of the second baffle to form a drain outlet.

[0013] With this configuration, the drain outlet is formed between the second end of the first baffle and the second end of the second baffle, which facilitates the flow of the mixed liquid in the collection chamber into the guide channel from the drain outlet.

[0014] In some embodiments of this application, the first baffle forms the first part of the peripheral wall.

[0015] With this configuration, the first part of the peripheral wall not only serves as the wall of the mixing box body, but also as the first baffle of the blocking component, which simplifies the structure, reduces material costs, and improves the space utilization rate within the mixing box body.

[0016] In some embodiments of this application, the guide includes a first guide wall and a second guide wall. The first guide wall is connected to the bottom wall and extends from a first end of the first baffle wall to a second outlet. The second guide wall is connected to the bottom wall and extends from a second end of the second baffle wall to a second outlet, and is spaced apart from the first guide wall to form a guide channel with a second opening at the top.

[0017] With this configuration, the guide and the bottom wall can cooperate to form a flow channel. Since the flow channel has a second opening, the resulting flow channel structure is simple.

[0018] In some embodiments of this application, the first guide wall constitutes the second part of the peripheral wall.

[0019] With this configuration, the second part of the peripheral wall not only serves as the wall of the mixing box body, but also as the second guide wall of the flow guide, thus simplifying the structure, reducing material costs, and improving the space utilization rate within the mixing box body.

[0020] In some embodiments of this application, along the flow direction of the flow channel, the second guide wall includes a first arc segment, a straight segment, and a second arc segment connected in sequence. The first arc segment protrudes towards the first guide wall, and the second arc segment protrudes away from the first guide wall. Alternatively, the second guide wall is an arc-shaped structure extending along the flow direction of the flow channel.

[0021] With this configuration, the first arc segment guides the mixture, the straight segment allows the mixture to flow relatively stably to the second arc segment, and the second arc segment maximizes the flow of the mixture into the second outlet. Alternatively, the second guide wall can also be designed as an arc shape according to the flow direction of the guide channel, thus ensuring smoother flow of the mixture.

[0022] In some embodiments of this application, in the arrangement direction of the cover assembly and the bottom wall, the size of the second guide wall is smaller than the size of the second baffle wall, and when the liquid storage box of the cleaning device is located inside the mixing box body, the second guide wall is located at the bottom of the liquid storage box of the cleaning device.

[0023] With this configuration, the space occupied by the liquid storage box and the second guide wall can be saved in the arrangement direction of the cover assembly and the bottom wall, thereby minimizing the height of the mixing box body. Since the second outlet is directly connected to the washing tank, the liquid flows faster at the second outlet than at the first outlet. Therefore, even if the size of the second guide wall is smaller than the size of the second baffle wall, the probability of liquid overflowing from the second opening in the guide channel is still low.

[0024] In some embodiments of this application, the distance between the second guide wall and the first guide wall is greater than or equal to the distance of the drain outlet in the circumferential direction of the first outlet.

[0025] This design prevents the flow rate of the mixture from suddenly increasing after it flows into the guide channel from the drain outlet, thus ensuring a balanced flow rate between the first and second guide walls and preventing the mixture from splashing out of the guide channel from the second opening.

[0026] In some embodiments of this application, the first inlet faces the side of the first outlet away from the drain outlet.

[0027] With this configuration, the water flowing out of the first inlet will flow to the first outlet, which is far from the drain outlet. Since this location is far from the drain outlet, the water can be gathered in the gathering chamber as much as possible, so that as much water as possible can enter the premixing device through the first outlet, while a small amount of water is discharged through the guide channel and the second outlet. This can reduce the probability of foam being generated after the laundry detergent and water are mixed.

[0028] In some embodiments of this application, the cover assembly includes a connected body and a first pipe. The body is fastened to the opening of the box, and the first pipe is located inside the mixing box body and above the first opening. The inlet end of the first pipe is used to communicate with a water source, and the outlet end of the first pipe is the first inlet. The liquid storage box of the cleaning device is used to store laundry detergent. The liquid storage box can be pulled between the cover assembly and the bottom wall through a pull-out opening on the peripheral wall. In the direction of pulling out the liquid storage box, the liquid storage box is located in front of the first pipe. The portion of the inner wall surface of the first pipe near the liquid storage box is closer to the bottom wall in the direction of the body assembly and further away from the liquid storage box in the direction of pulling out the liquid storage box.

[0029] This design directs the water in the first pipe as far away from the storage box as possible, thereby reducing water splashing onto the outer wall of the storage box, preventing water from entering the storage box through the weld seams, and preventing water from diluting the detergent inside the storage box.

[0030] In some embodiments of this application, the mixing box further includes a plurality of spaced-apart diverter columns disposed within the converging chamber.

[0031] By setting multiple diversion columns in the converging chamber, the water and laundry detergent mixture entering the converging chamber can be diverted and refined, thereby preventing the mixture from splashing onto the outer wall of the storage box, keeping the storage box clean and improving the user experience. At the same time, it also prevents the mixture from splashing into the storage box, thus preventing it from diluting the laundry detergent inside the storage box and improving the user experience.

[0032] In some embodiments of this application, the cover assembly has a water channel, which includes an inlet end and a first outlet end. The inlet end is connected to a water source, and the first outlet end is connected to a first inlet end.

[0033] The mixing box also includes a flow restrictor, which is located in the water channel. A flow restrictor opening is formed at the flow restrictor opening on the flow path of the water channel. The cross-sectional area of ​​the flow restrictor opening is smaller than the cross-sectional area of ​​the first outlet.

[0034] With this configuration, when the water in the water channel passes through the flow limiting component, it will continue to flow through the flow limiting port. Since the cross-sectional area of ​​the flow limiting port is smaller than that of the first outlet, the flow rate decreases and the velocity increases when the water passes through the flow limiting port. When it passes through the first outlet, the flow rate increases again and the velocity decreases. This can reduce the splashing of the water discharged from the first outlet and ensure that the water can smoothly enter the collecting chamber.

[0035] In some embodiments of this application, the flow restrictor includes a baffle, and a flow restrictor opening is formed between the baffle and a portion of the inner peripheral wall of the water channel in the plane containing the cross-section of the water channel.

[0036] With this configuration, the flow restriction port is formed between the baffle and part of the inner peripheral wall, which facilitates the formation of the flow restriction port.

[0037] In some embodiments of this application, along the direction of the water channel extending from the inlet end to the first outlet end, the baffle is inclined to form a flow-limiting channel with a gradually narrowing cross-section with the inner wall surface of the water channel, and the flow-limiting port is the outlet of the flow-limiting channel.

[0038] In this way, water will pass through the flow-limiting channel to the flow-limiting outlet. Because the cross-section of the flow-limiting channel is gradually narrowing, it can gently guide the water as it passes through, making the sudden change in water flow at the baffle a gradual process and resulting in a smoother flow. Furthermore, since the inclination of the baffle matches the direction of the water flow, the impact force of the water on the baffle can be reduced, extending the baffle's service life.

[0039] In some embodiments of this application, the mixing box further includes a liquid extraction column, which is connected to the cap assembly and located within the mixing box body. The liquid extraction column has a liquid extraction channel inside, the inlet end of which is used to communicate with the clothing treatment agent, and the outlet end of which is connected to the inlet end of the second inlet. At least the second inlet near the liquid extraction column is lower than the lowest point of the liquid extraction column.

[0040] This design, where the second inlet closest to the suction column is lower than the lowest point of the column, prevents the laundry detergent entering through the second inlet from splashing onto the suction column, thus improving detergent utilization. It also prevents detergent from adhering to the outer wall of the reservoir after contact with the suction column, enhancing the user experience.

[0041] In some embodiments of this application, the mixing box further includes a premixing device, which includes a Venturi tube with a negative pressure port on its side wall, a first outlet connected to the negative pressure port, an inlet end of the Venturi tube for connection to a water source, and an outlet end of the Venturi tube for connection to a washing tub.

[0042] With this design, when water flows through the venturi tube, the water flow in the venturi tube can generate negative pressure at the negative pressure port. Under the action of the negative pressure at the negative pressure port, the mixed liquid and air in the collecting chamber can be drawn into the venturi tube through the negative pressure port. The mixed liquid, air and water passing through the venturi tube can be fully mixed and foamed. The fully mixed liquid can then enter the washing tub through the outlet end of the venturi tube, thus improving the cleaning effect of clothes.

[0043] In some embodiments of this application, the mixing box also includes a pressure relief valve, and the side wall of the venturi tube also has a pressure relief port, which is located upstream of the negative pressure port and is connected to the converging chamber through the pressure relief valve.

[0044] This design allows for efficient water drainage. If a section of the Venturi tube at the negative pressure port becomes blocked, the pressure relief valve can be opened to allow water from that section upstream of the negative pressure port to drain into the collecting chamber. This protects the Venturi tube from rupture due to blockage and water pressure, ensuring the overall reliability of the mixing box. Furthermore, because the pressure relief valve is connected to the collecting chamber, water can enter the chamber and then flow into the washing tub through the second inlet / outlet, maximizing water utilization.

[0045] The second aspect of this application provides a dispensing device for a cleaning equipment, including a liquid storage box and a mixing box of the cleaning equipment in any of the above embodiments. The liquid storage box is removably disposed within the mixing box body and is used to connect to a converging chamber through a second inlet.

[0046] In the technical solutions of this application embodiment, since the mixing box in any of the above embodiments is included, the same beneficial effects can be achieved.

[0047] A third aspect of this application provides a cleaning device, including a washing tub and a mixing box or a dispensing device of the cleaning device in any of the above embodiments.

[0048] In the technical solutions of this application embodiment, since the mixing box or the dispensing device in any of the above embodiments is included, the same beneficial effects can be achieved. Attached Figure Description

[0077] The following is a detailed description of this application.

[0078] Washing machines are widely used as common household appliances. There are many types of washing machines, such as front-loading washing machines, top-loading washing machines, or washer-dryer combos, which can meet users' clothing cleaning needs.

[0079] Based on this, such as Figure 1 As shown, this application provides a cleaning device 01, which includes a washing tub 2 and a mixing box 12 or a dispensing device 1.

[0080] The mixing box 12 and the dispensing device 1 of the cleaning equipment 01 refer to devices for dispensing a mixture of laundry detergent and water into the washing tub 2 to clean clothes. The laundry detergent refers to at least one of detergent and fabric softener.

[0081] In addition, cleaning equipment 01 includes a washing machine, which can be a front-loading washing machine, a top-loading washing machine, or a washer-dryer combo, etc.

[0082] In some examples, such as Figure 1 As shown, the cleaning device 01 also includes a housing 3. The mixing box 12 or dispensing device 1 of the cleaning device 01 is disposed on the housing 3 to dispense a mixture of laundry detergent and water into the washing tub 2. For a drum washing machine, the clothes are cleaned by the rotation of the washing tub 2 and the cooperation of the mixture.

[0083] For example, the dispensing device 1 or the mixing box 12 can be installed on the front side of the housing 3, which facilitates the operation of the mixing box 12 or the dispensing device 1. For example, the cleaning device 01 is a drum washing machine, and the front side of the housing 3 refers to the side of the housing 3 with a door, which is used to open or close the dispensing port of the washing tub 2.

[0084] With the above configuration, the outer shell 3 provides support for the washing tub 2 and the mixing box 12 or the dispensing device 1. The washing tub 2 is used to hold clothes, and the mixing box 12 or the dispensing device 1 is used to dispense the mixed liquid into the washing tub 2. The clothes are cleaned by the rotation of the washing tub 2 and the cooperation of the mixed liquid.

[0085] Based on this, such as Figures 2-5 As shown, this application also provides a dispensing device 1 for a cleaning device 01. The dispensing device 1 includes a liquid storage box 11 and a mixing box 12 of the cleaning device 01. The liquid storage box 11 is removably disposed in the mixing box body 122 on the mixing box 12 and is used to connect to the converging chamber e inside the mixing box 12 through the second inlet b on the mixing box 12.

[0086] It is understandable that the liquid storage box 11 is connected to the converging chamber e through the second inlet b on the mixing box 12, meaning that the liquid storage box 11 is connected to the inlet end of the second inlet b, and the outlet end of the second inlet b is connected to the converging chamber e.

[0087] The liquid storage box 11 is used to hold the laundry treatment agent. For example, the liquid storage box 11 has two liquid tanks, which can be used to hold detergent and fabric softener respectively. The two liquid tanks are connected to the converging chamber e through the second inlet b on the mixing box 12, so as to add detergent and fabric softener into the converging chamber e.

[0088] With the above configuration, the liquid storage box 11 is removably installed inside the mixing box body 122. After the liquid storage box 11 is pushed into the mixing box body 122, the liquid holding tank inside the liquid storage box 11 will communicate with the converging chamber e inside the mixing box body 122 through the second inlet b, so as to add fabric softener and detergent into the converging chamber e. After the liquid storage box 11 is pulled out of the mixing box body 122, fabric softener and detergent can be added to the holding tank. The liquid storage box 11 facilitates the replenishment and addition of fabric softener and detergent.

[0089] In related technologies, the mixing tank 12 generally includes a mixing tank body 122, a storage tank 11, and a dispensing pipe. The mixing tank body 122 is housed within the outer casing 3, and the storage tank 11 is removably placed inside the mixing tank body 122, providing detergent, fabric softener, and other laundry detergents to the mixing tank body 122. The mixing tank body 122 is not only connected to a water source but also connected to the washing tub 2 via the dispensing pipe. With this configuration, after water and laundry detergent enter the mixing tank body 122, they undergo a simple mixing process with the water to form a mixture, which is then dispensed into the washing tub 2 through the dispensing pipe.

[0090] However, the mixture tends to flow around inside the mixing box body 122, so the mixture will inevitably flow to the unwanted locations inside the mixing box body 122.

[0091] Based on this, such as Figures 3-5As shown in the illustration, this application embodiment also provides a mixing box 12 for a cleaning device 01. The mixing box 12 includes a cover assembly 121, a mixing box body 122, a blocking member 123, and a guide member 124. The cover assembly 121 has a first inlet a and a second inlet b. The cover assembly 121 is fastened to the opening of the mixing box body 122. The mixing box body 122 has a first outlet c and a second outlet d. The first outlet c is used to connect to a premixing device, and the second outlet d is used to connect to the washing tub 2 of the cleaning device 01. The blocking member 123 is disposed inside the mixing box body 122 and is arranged around the first outlet c to form a converging chamber e. The first inlet a is used to connect a water source and the converging chamber e, and the second inlet b is used to connect a laundry detergent and the converging chamber e. The second outlet d is located outside the converging chamber e, and the blocking member 123 has a drain port f connecting to the converging chamber e. The guide 124 is disposed inside the mixing box body 122. The guide 124 extends from the drain port f to the second outlet d and forms a flow channel g connecting the second outlet d and the drain port f.

[0092] It is understandable that there is a space within the mixing box body 122, in which the converging chamber e, the guiding channel g, and the storage box 11 are all located.

[0093] In some examples, such as Figure 5 As shown, there are two second inlets b, and the liquid storage box 11 has two liquid tanks, each including a first liquid tank and a second liquid tank. One second inlet b connects the first liquid tank and the converging chamber e, and the other second inlet b connects the second liquid tank and the converging chamber e. Thus, the user can add at least one of a laundry detergent and a fabric softener to the two liquid tanks as needed to meet clothing cleaning requirements. For example, both liquid tanks can contain laundry detergent, or one liquid tank can contain laundry detergent and the other liquid tank can contain fabric softener.

[0094] In some examples, such as Figures 6-9 As shown, the cover assembly 121 has a water channel h and a laundry detergent channel i. The water channel h includes an inlet end, a first outlet end, and a second outlet end. The inlet end is connected to a water source, the first outlet end is connected to a first inlet a, and the second outlet end is connected to the washing tub through a spray pipe. The inlet end of the laundry detergent channel i is connected to the liquid storage box 11, and the outlet end of the laundry detergent channel i is connected to a second inlet b.

[0095] With this configuration, water can flow through the first outlet of water channel h to the first inlet a, and then enter the converging chamber e through the first inlet a. The laundry detergent can flow through the laundry detergent channel i to the second inlet b, and then enter the converging chamber e through the second inlet b. Simultaneously, water can also flow through the second outlet of water channel h and the spray pipe into the washing tub to spray and wet the clothes. This not only improves the integration of water channel h and laundry detergent channel i, but also enhances the overall aesthetics of the mixing box 12 since both water channel h and laundry detergent channel i are concealed inside the cover assembly 121.

[0096] For example, such as Figures 7-8 As shown, there are two second inlets b. The mixing box 12 also includes a pump body 125, which is connected to the cover assembly 121 and located outside the mixing box body 122. There are two pump bodies 125 and two laundry detergent channels i. The pump bodies 125 and laundry detergent channels i correspond one-to-one. One laundry detergent channel i, pump body 125, and second inlet b are used to dispense laundry detergent from the first liquid tank, and the other laundry detergent channel i, pump body 125, and second inlet b are used to dispense laundry detergent from the second liquid tank. For example, the pump body 125 is a piston pump.

[0097] The garment treatment agent channel i includes a first sub-segment i1 and a second sub-segment i2. The inlet end of the first sub-segment i1 is connected to the liquid holding tank, and the outlet end of the first sub-segment i1 is connected to the inlet end of the pump body 125. The outlet end of the pump body 125 is connected to the inlet end of the second sub-segment i2, and the outlet end of the second sub-segment i2 is connected to the second inlet b. This arrangement not only allows the pump body 125 to provide power to the garment treatment agent, facilitating its entry into the mixing box body 122, but also saves space inside the mixing box body 122 because the pump body 125 is located outside the mixing box body 122.

[0098] In addition, for example, the distance between the two second inlets b corresponding to the two clothing treatment agent channels i can be set to be relatively close, so that the clothing treatment agents discharged from both the first liquid tank and the second liquid tank are in the same area, which facilitates the control of the size of the converging chamber e and the volume of the mixing box body 122.

[0099] With the above configuration, the cover assembly 121 is fastened to the opening above the mixing tank body 122. External water can be introduced into the collecting chamber e inside the mixing tank body 122 through the first inlet a, while the laundry detergent can be introduced into the collecting chamber e inside the mixing tank body 122 through the second inlet b. In the collecting chamber e, the laundry detergent and water will undergo a simple mixing to form a mixture, which will then be discharged into the washing tub 2 through the first outlet c, thereby achieving the washing of clothes in the washing tub 2. Since the collecting chamber e has a drain outlet f, the mixture that is not discharged through the first outlet c in time will flow through the guide channel g to the second outlet d and be discharged into the washing tub 2 from the second outlet d.

[0100] In addition, by setting the blocking member 123 and the guide member 124, the mixed liquid can enter the converging chamber e as much as possible, and then enter the premixing device through the first outlet c to achieve the mixing of water and laundry detergent, thereby improving the cleaning degree of clothes. The excess liquid can be discharged into the washing tub 2 through the guide channel g and the second outlet d under the guidance of the guide member 124, thereby preventing the mixed liquid from flowing to the unwanted position in the mixing box 12.

[0101] In some embodiments, such as Figures 6-8 As shown, the cover assembly 121 has a water channel h, which includes an inlet end and a first outlet end. The inlet end is connected to a water source, and the first outlet end is connected to a first inlet a. The mixing box 12 also includes a flow restrictor 132, which is disposed within the water channel h. A flow restrictor p is formed at the flow restrictor 132 on the flow path of the water channel h, and the cross-sectional area of ​​the flow restrictor p is smaller than the cross-sectional area of ​​the first outlet c.

[0102] It is understandable that the flow restriction port p is formed on the flow path of the water channel h, meaning that the water in the water channel h needs to pass through the flow restriction port p during its flow. In addition, the flow restriction port p formed at the flow restriction component 132 can be formed by the flow restriction component 132 itself, or it can be formed by the flow restriction component 132 and the inner wall surface of the water channel h.

[0103] By setting a flow restrictor 132 in the water channel h, the water in the water channel h will continue to flow through the flow restrictor p when it passes through the flow restrictor 132. Since the cross-sectional area of ​​the flow restrictor p is smaller than the cross-sectional area of ​​the first outlet c, the flow rate decreases and the velocity increases when the water passes through the flow restrictor p. When it passes through the first outlet c, the flow rate increases again and the velocity decreases. In this way, the splashing degree of the water discharged from the first outlet c can be reduced, ensuring that the water can smoothly enter the converging chamber e.

[0104] In some embodiments, such as Figure 8As shown, the flow restrictor 132 includes a baffle, and the flow restrictor p is formed between the baffle and a portion of the inner peripheral wall 1222 of the water channel h in the plane containing the cross-section of the water channel h.

[0105] In some examples, in the plane containing the cross-section of the water channel h, a first side of the baffle is connected to the cover assembly 121 constituting the water channel h, and a second side of the baffle opposite to the first side is spaced apart from a portion of the inner peripheral wall 1222 of the water channel h to form a flow-limiting port p.

[0106] The baffle can be a curved arc-shaped plate or a flat plate, depending on the specific requirements.

[0107] For example, the baffle and the cover assembly 121 constituting the water channel h can be integrally molded, so that the cover assembly 121 and the baffle can be processed in one go, avoiding secondary processing and reducing processing steps.

[0108] Alternatively, the baffle and the cover assembly 121 constituting the water channel h can be processed separately and then connected together by a suitable method such as bonding, welding, or screw fastening.

[0109] In addition, the plane on which the baffle is located (whether the baffle is an arc-shaped plate or a straight plate) can be set at an angle to or parallel to the cross-section of the water channel h at its location.

[0110] With the above configuration, the flow limiting element 132 has a baffle structure, which facilitates the processing and setting of the baffle. Since the flow limiting port p is formed between part of the peripheral edge and part of the inner peripheral wall 1222 of the baffle, it is easy to form the flow limiting port p.

[0111] In some embodiments, such as Figure 8 As shown, along the direction of the water channel h extending from the inlet end to the first outlet end, the baffle is inclined to form a flow-limiting channel q with a gradually narrowing cross-section with the inner wall of the water channel h, and the flow-limiting port p is the outlet of the flow-limiting channel q.

[0112] For example, such as Figure 8 As shown, the area between the dividing line Q1 and the dividing line Q2 represents the flow-limiting channel q.

[0113] In this way, the water will pass through the flow-limiting channel q to the flow-limiting outlet p. Since the cross-section of the flow-limiting channel q is gradually narrowing, it can gently guide the water as it passes through, making the sudden change in water flow at the baffle a gradual process and resulting in a smoother flow. Furthermore, because the inclination of the baffle matches the direction of the water flow, the impact force of the water on the baffle can be reduced, extending the baffle's service life.

[0114] For premixing devices, the premixing device can be a tubular structure utilizing the Venturi principle, or it can be a structure with a stirring function. The following is a detailed description.

[0115] In some embodiments, such as Figure 9 , Figure 10 As shown, the mixing box 12 includes a premixing device, which includes a venturi tube 126. The side wall of the venturi tube 126 has a negative pressure port. The first outlet c is connected to the negative pressure port. The inlet end of the venturi tube 126 is connected to a water source, and the outlet end of the venturi tube 126 is connected to the washing tub 2.

[0116] In some examples, the inlet of the Venturi tube 126 is connected to a faucet, and the outlet of the Venturi tube 126 is connected to the washing tub 2 via a spray head. The faucet uses its own power to generate water, causing a high-speed water flow through the Venturi tube 126 to create a negative pressure at the negative pressure port. This allows the mixed liquid and air in the collecting chamber e to be drawn into the Venturi tube 126 through the negative pressure port, where they mix to form a mixed cleaning solution. This mixed cleaning solution is then sprayed into the washing tub 2 through the spray head to soak the clothes and improve the subsequent cleaning effect.

[0117] With the above configuration, when water flows through the Venturi tube 126, the water flow through the Venturi tube 126 can generate negative pressure at the negative pressure port. Under the action of the negative pressure at the negative pressure port, the mixed liquid and air in the collecting chamber e can be drawn into the Venturi tube 126 through the negative pressure port. The mixed liquid, air and water passing through the Venturi tube 126 can be fully mixed and foamed. The fully mixed liquid can then enter the washing tub through the outlet end of the Venturi tube 126, thus improving the cleaning effect of clothes.

[0118] In some embodiments, such as Figure 9 , Figure 10 As shown, the mixing box 12 also includes a pressure relief valve 127, and the side wall of the venturi tube 126 also has a pressure relief port, which is located upstream of the negative pressure port. The pressure relief port is connected to the converging chamber e through the pressure relief valve 127.

[0119] The pressure relief valve 127 can extend into the converging chamber e to communicate with it. Since the first outlet c is located in the converging chamber e and is connected to the negative pressure port of the venturi tube 126, and since part of the pressure relief valve 127 also extends into the converging chamber e, the distance between the venturi tube 126 and the pressure relief valve 127 is relatively short. Therefore, the venturi tube 126 and the pressure relief valve 127 can be integrated together, which facilitates the overall installation of the two and improves the integration.

[0120] It is understandable that the pressure relief port is located upstream of the negative pressure port, meaning that along the flow direction of water inside the Venturi tube 126, the pressure relief port is located behind the negative pressure port.

[0121] With the above configuration, when a section of the Venturi tube 126 at the negative pressure port becomes blocked (usually at the narrower throat of the Venturi tube 126), the pressure relief valve 127 can be opened to discharge water from the section of the Venturi tube 126 upstream of the negative pressure port into the collecting chamber e through the pressure relief port and valve. This protects the Venturi tube 126 from rupture under water pressure due to blockage, ensuring the overall reliability of the mixing box 12. Furthermore, since the pressure relief valve 127 is connected to the collecting chamber e, water can enter the collecting chamber e, allowing it to enter the washing tub through the second outlet, thus achieving full utilization of water.

[0122] In some embodiments, such as Figure 9 , Figure 10 As shown, the mixing box 12 also includes a dispensing pipe 128. The inlet end of the dispensing pipe 128 is connected to the second outlet d, and the outlet end of the dispensing pipe 128 is connected to the washing tank 2. The diameter of the second outlet d is larger than the diameter of the first outlet c. The pipe diameter of the dispensing pipe 128 is set to be larger, so that the mixed liquid that does not enter the first outlet c in time can enter the washing tank 2 in time through the guide channel g and the second outlet d, so as to avoid the mixed liquid flowing to other positions in the mixing box body 122.

[0123] For example, the delivery pipe 128 can be a corrugated pipe, which can shrink or stretch itself to adapt to the spatial layout.

[0124] In some embodiments, such as Figures 11-13 As shown, the mixing box body 122 includes a connected bottom wall 1221 and a peripheral wall 1222. The peripheral wall 1222 is arranged circumferentially along the bottom wall 1221 to form a box opening opposite to the bottom wall 1221. The second outlet d is located on the bottom wall 1221. A blocking member 123 is located between the cover assembly 121 and the bottom wall 1221 and extends from the bottom wall 1221 toward the cover assembly 121 to form a converging chamber e with a first opening j at its top. The first inlet a and the second inlet b both face the first opening j. The first outlet c is located on the portion of the bottom wall 1221 opposite to the first opening j.

[0125] It is understandable that the converging chamber e is a structure with a first opening j formed by the cooperation of the bottom wall 1221, the peripheral wall 1222, and the blocking member 123.

[0126] In some examples, the vertical projections of the first inlet a and the second inlet b onto the bottom wall 1221 fall within the range of the vertical projection of the converging chamber e onto the bottom wall 1221, thereby allowing the liquid discharged from the first inlet a and the liquid discharged from the second inlet b to enter the converging chamber e.

[0127] In some examples, a pull-out opening is provided on the peripheral wall 1222, through which the liquid storage box 11 can be pushed into or pulled out of the mixing box body 122.

[0128] In some examples, along the pulling direction of the liquid storage box 11, the second outlet d is located closer to the pull opening than the first outlet c, in order to accommodate the spatial layout within the mixing box body 122.

[0129] In some examples, a portion of the bottom wall 1221 at the pull-out port is higher than a portion of the bottom wall 1221 at the second outlet d. The height difference between the portion of the bottom wall 1221 at the pull-out port and the portion of the bottom wall 1221 at the second outlet d is greater than a first threshold. This can prevent liquid at the second outlet d from overflowing from the pull-out port and ensure the overall reliability of the mixing box 12.

[0130] With the above configuration, a converging chamber e with a first opening j at the top can be formed on the bottom wall 1221. Since the first inlet a and the second inlet b both face the first opening j of the converging chamber e, water and laundry detergent can both enter the converging chamber e through the first opening j, which facilitates the addition of water and laundry detergent.

[0131] In some embodiments, such as Figures 11-13 As shown, along the circumferential direction of the first outlet c, the blocking member 123 includes a first baffle 1231 and a second baffle 1232 arranged sequentially. The first end of the first baffle 1231 is adjacent to and connected to the first end of the second baffle 1232. The second end of the first baffle 1231 is adjacent to and spaced apart from the second end of the second baffle 1232 to form a drain outlet f.

[0132] With the above configuration, the drain port f is formed between the second end of the first baffle 1231 and the second end of the second baffle 1232, which facilitates the formation of the drain port f. In addition, since the drain port f extends from the bottom wall 1221 to the position of the first opening j, it is convenient for the mixed liquid in the collecting chamber e to enter the guide channel g from the drain port f.

[0133] Of course, in other embodiments, through holes can be directly opened on the side wall of the blocking member 123 to form a drain port f.

[0134] The first baffle 1231 can be part of the wall of the mixing box body 122, or it can be a separate structure set on the bottom wall 1221, independent of the wall of the mixing box body 122. The specific choice can be made according to the needs.

[0135] In some embodiments, such as Figures 11-13 As shown, the first baffle 1231 constitutes the first part of the peripheral wall 1222.

[0136] In some examples, the first portion of the peripheral wall 1222 may include a rear portion and a left portion of the peripheral wall 1222, and the converging chamber e may be formed at the rear corner of the mixing tank body 122. This avoids interference between the converging chamber e and the front reservoir 11.

[0137] In this way, the first part of the peripheral wall 1222 not only serves as the wall (peripheral wall 1222) of the mixing box body 122, but also serves as the first baffle wall 1231 of the baffle 123. This simplifies the structure, reduces the processing difficulty, reduces the material cost, and also improves the space utilization rate inside the mixing box body 122.

[0138] In some embodiments, such as Figures 11-13 As shown, the guide 124 includes a first guide wall 1241 and a second guide wall 1242. The first guide wall 1241 is connected to the bottom wall 1221 and extends from the first end of the first baffle 1231 to the second outlet d. The second guide wall 1242 is connected to the bottom wall 1221 and extends from the second end of the second baffle 1232 to the second outlet d, and is spaced apart from the first guide wall 1241 to form a flow channel g with a second opening at the top.

[0139] It is understandable that the wall of the flow channel g is formed by the first guide wall 1241, the second guide wall 1242 and the bottom wall 1221, wherein the first guide wall 1241 and the second guide wall 1242 mainly play a guiding role.

[0140] With the above configuration, the first guide wall 1241, the second guide wall 1242, and the bottom wall 1221 can cooperate to form a flow channel g. The first guide wall 1241 and the second guide wall 1242 play a guiding role to ensure that the mixed liquid flowing out of the drain port f can smoothly pass through the flow channel g and enter the second outlet d. In addition, since the flow channel g has a second opening, the structure of the formed flow channel g is simple.

[0141] The first guide wall 1241 can be part of the wall of the mixing box body 122, or it can be a separate structure set on the bottom wall 1221, independent of the wall of the mixing box body 122. The specific choice can be made according to the needs.

[0142] In some embodiments, such as Figures 11-13 As shown, the first guide wall 1241 constitutes the second part of the peripheral wall 1222.

[0143] In some examples, the second part of the peripheral wall 1222 can be the part on the left side of the peripheral wall 1222 located in front of the first part of the peripheral wall 1222, and the first part and the second part of the peripheral wall 1222 can be a continuous structure arranged sequentially along the circumference of the bottom wall 1221.

[0144] In this way, since the second part of the peripheral wall 1222 not only serves as the wall of the mixing box body 122, but also as the second guide wall 1242 of the flow guide, the structure can be simplified, the material cost can be reduced, and the space utilization rate inside the mixing box body 122 can be improved.

[0145] In some embodiments, such as Figure 11 As shown, along the flow direction of the flow channel g, the second guide wall 1242 includes a first arc segment k1, a straight segment k2 and a second arc segment k3 connected in sequence. The first arc segment k1 protrudes in a direction close to the first guide wall 1241, and the second arc segment k3 protrudes in a direction away from the first guide wall 1241.

[0146] The first arc segment k1, the straight segment k2, and the second arc segment k3 can be integrally formed, allowing the second guide wall 1242 to be processed in one go, reducing the number of processing steps. Alternatively, the first arc segment k1, the straight segment k2, and the second arc segment k3 can be processed separately and then connected together.

[0147] With the above configuration, the first arc segment k1 can guide the mixture, the straight segment k2 allows the mixture to flow relatively stably to the second arc segment k3, and the second arc segment k3 can maximize the flow of the mixture into the second outlet d. This design of the second guide wall 1242 facilitates the guidance of the mixture.

[0148] In other embodiments, the second guide wall 1242 is an arc-shaped structure extending along the flow direction of the flow channel g.

[0149] The arc-shaped structure can protrude towards the first guide wall 1241, or it can protrude away from the first guide wall 1241.

[0150] With this configuration, the second guide wall 1242 is an arc-shaped structure. The curvature of this arc-shaped structure can be determined according to the flow direction of the guide channel g, which can ensure smoother flow of the mixed liquid.

[0151] In some embodiments, such as Figure 14 As shown, in the arrangement direction of the cover assembly 121 and the bottom wall 1221, the size of the second guide wall 1242 is smaller than the size of the second baffle wall 1232, that is, the height of the second guide wall 1242 is smaller than the height of the second baffle wall 1232. When the liquid storage box 11 is located inside the mixing box body 122, the second guide wall 1242 is located at the bottom of the liquid storage box 11.

[0152] In some examples, along the pulling direction of the reservoir 11 ( Figure 14(In the vertical direction), the second outlet d is located on the side of the first outlet c near the pull-out port, and the second guide wall 1242 is located on the side of the second baffle wall 1232 near the pull-out port. In this way, the liquid flowing into the guide channel g from the drain port f can be smoothly introduced into the second outlet d.

[0153] In this way, not only is the flow guiding effect of the flow guiding channel g guaranteed, but also the space occupied by the liquid storage box 11 and the second guide wall 1242 can be saved in the arrangement direction of the cover assembly 121 and the bottom wall 1221, thereby minimizing the size of the mixing box body 122 in the height direction.

[0154] In some embodiments, such as Figure 11 As shown, the distance between the second guide wall 1242 and the first guide wall 1241 is greater than or equal to the distance of the outlet f in the circumferential direction of the first outlet c.

[0155] In some examples, where the second guide wall 1242 includes a first arc segment k1, a straight segment k2, and a second arc segment k3, it is necessary to ensure that the distance between the first arc segment k1 and the first guide wall 1241, and the distance between the straight segment k2 and the first guide wall 1241, are both greater than or equal to the distance of the outlet f in the circumferential direction of the first outlet c.

[0156] In this way, after the mixture flows into the guide channel g from the drain outlet f, the flow rate of the mixture slows down, thereby ensuring a stable flow rate of the mixture between the first guide wall 1241 and the second guide wall 1242, and preventing the mixture from splashing out of the guide channel g.

[0157] In some embodiments, such as Figure 15 As shown, the first inlet a faces the side of the first outlet c away from the pressure relief port.

[0158] For example, the first inlet a can be tilted to face away from the first outlet c and away from the pressure relief port.

[0159] With the above settings, the water flowing out of the first inlet a will flow to the first outlet c, which is far away from the drain outlet f. Since this location is far from the drain outlet f, the water can be gathered in the gathering chamber e as much as possible, so that as much water as possible can enter the premixing device through the first outlet c, while a small portion of the water is discharged through the guide channel g and the second outlet d. This can reduce the probability of foam being generated after the clothing treatment agent and water are mixed.

[0160] In some embodiments, such as Figure 15 or Figure 16As shown, the cover assembly 121 includes a connected body portion 1215 and a first pipe 1213. The body portion 1215 is fastened to the box opening. The first pipe 1213 is located inside the mixing box 12 body and above the first opening j. The inlet end of the first pipe 1213 is used to communicate with a water source, and the outlet end of the first pipe 1213 is the first inlet a. The liquid storage box 11 of the cleaning device 01 can be pulled out between the cover assembly 121 and the bottom wall 1221 through the pull-out port on the peripheral wall 1222. Along the direction in which the liquid storage box 11 is pulled out, the liquid storage box 11 is located in front of the first pipe 1213.

[0161] The inner wall of the first pipe 1213 near the liquid storage box 11 is closer to the bottom wall 1221 in the direction of the main body 1215 approaching the bottom wall 1221, and further away from the liquid storage box 11 in the direction of extraction of the liquid storage box 11.

[0162] For example, such as Figure 15 or Figure 16 As shown, the water channel h and the detergent channel are located inside the main body 1215. The main body 1215 includes a base 1211 and a top cover 1212. The base 1211 is disposed between the top cover 1212 and the bottom wall 1221 of the mixing box body 122. The top cover 1212 and the base 1211 are fastened together to form the water channel h and the laundry detergent channel i. This arrangement facilitates the processing of the water channel h and the laundry detergent channel i.

[0163] In some examples, along the inner periphery of the first pipe 1213, the inner wall surface of the first pipe 1213 includes a first inner wall surface and a second inner wall surface. The second inner wall surface is located on the side of the first inner wall surface away from the liquid storage box 11. That is, the first inner wall surface is located on the side of the second inner wall surface close to the liquid storage box 11. In other words, the closer the first inner wall surface is to the bottom wall 1221 in the direction of the body part 1215, the further away it is from the liquid storage box 11 in the direction of extraction of the liquid storage box 11.

[0164] The extension direction of the inner wall of the first pipe 1213, and the boundary line between the first inner wall and the second inner wall can be the location where the angle between the two changes abruptly.

[0165] With the above settings, the water in the first pipe 1213 can be directed as far away from the liquid storage box 11 as possible, thereby reducing water splashing onto the outer wall of the liquid storage box 11, preventing water from entering the liquid storage box 11 through the weld seam on the liquid storage box 11, and preventing water from diluting the detergent in the liquid storage box 11.

[0166] In some embodiments, such as Figure 14As shown, the mixing box 12 also includes a liquid extraction column 129, which is connected to the cover assembly 121 and located inside the mixing box body 122. The liquid extraction column 129 has a liquid extraction channel 130 inside. The inlet end of the liquid extraction channel 130 is used to communicate with the clothing treatment agent, and the outlet end of the liquid extraction channel 130 is connected to the inlet end of the second inlet b. At least the second inlet b near the liquid extraction column 129 is lower than the lowest point of the liquid extraction column 129.

[0167] It is understandable that, when the mixing box 12 includes a storage box, the inlet end of the liquid extraction channel 130 is connected to the liquid holding tank inside the storage box 11.

[0168] In some examples, there are two second inlets b and two liquid extraction channels 130, which correspond one-to-one. The two liquid extraction channels 130 correspond to the clothing treatment agent in the two liquid tanks (the first liquid tank and the second liquid tank) of the liquid storage box 11, respectively.

[0169] In some examples, when the cover assembly 121 has a clothing treatment channel i, the outlet end of the extraction channel 130 is connected to the inlet end of the clothing treatment channel i, and the outlet end of the clothing treatment channel i is connected to the inlet end of the second inlet b, so that the storage box 11 is connected to the interior of the mixing box body 122 through the extraction channel 130, the clothing treatment channel i, and the second inlet b.

[0170] For example, the cover assembly 121 includes a body portion 1215 and a second pipe 1214. The laundry detergent channel i is located within the body portion 1215, and the second pipe 1214 is located within the mixing box body 122. The inlet end of the second pipe 1214 is connected to the outlet end of the laundry detergent channel i, and the outlet end of the second pipe 1214 is a second inlet b. By setting the second pipe 1214, the height of the second inlet b can be easily adjusted, for example, so that the second inlet b is lower than the suction column 129, which facilitates manufacturing design.

[0171] For example, there are two second inlets b, one for dispensing the laundry detergent from the first container and the other for dispensing the laundry detergent from the second container. There are two second pipes 1214, and the distance between the two second pipes 1214 is greater than a second threshold. This can prevent the fabric softener and detergent from mixing due to being too close together, and can prevent the mixture of fabric softener and detergent from clogging the second inlet b.

[0172] In this case, based on the setting of two second pipes 1214, the second inlet b corresponding to both second pipes 1214 can be lower than the liquid extraction column 129, or only the second inlet b corresponding to the second pipe 1214 that is close to the liquid extraction column 129 can be lower than the liquid extraction column 129.

[0173] In this way, because the second inlet b is lower than the lowest point of the extraction column 129 inside the mixing box body 122, the laundry detergent entering from the second inlet b can be prevented from splashing onto the extraction column 129, thereby improving the utilization rate of the laundry detergent and the accuracy of the dosage. Additionally, it also prevents the laundry detergent from adhering to the outer wall of the storage box 11 after contact with the extraction column 129, thus improving the user experience.

[0174] For example, the distance between the two second pipes 1214 is less than the third threshold, which ensures that the laundry detergent in the first liquid tank and the second liquid tank are dispensed at similar angles, so that the laundry detergent and water in the first liquid tank and the laundry detergent and water in the second liquid tank can be fully mixed. The mixed liquid can enter the first outlet c in large quantities, and the mixed liquid that does not enter the first outlet c can enter the second outlet d, thereby reducing liquid splashing in the process.

[0175] In some embodiments, such as Figure 13 As shown, the mixing box 12 also includes a plurality of spaced-apart diversion columns 131, which are disposed in the converging chamber e.

[0176] It is understandable that the number of diversion columns 131 can be selected as needed. For example, the number of diversion columns 131 can be 10, 20, 25, or 30, etc.

[0177] The multiple diversion columns 131 can be arranged in a square array. For example, 20 diversion columns 131 can be arranged in a square structure with 4 rows and 5 columns. Of course, the multiple diversion columns 131 can also be arranged randomly.

[0178] In addition, the diversion column 131 can be a regular shape such as a cylindrical or prismatic structure. Of course, the diversion column 131 can also be an irregular cylindrical structure.

[0179] By setting multiple diversion columns 131 inside the converging chamber e, the diversion columns 131 can divert and refine the mixture of water and laundry detergent entering the converging chamber e, thereby preventing the mixture from splashing onto the outer wall of the storage box 11, ensuring the surface of the storage box 11 is clean and improving the user experience. At the same time, it can also prevent the mixture from splashing into the storage box 11, preventing it from diluting the laundry detergent inside the storage box 11, thus improving the user experience.

[0180] In some embodiments, the mixing box 12 includes both a diverting column 131 and a flow restrictor 132. With the cooperation of the flow restrictor p and the first inlet a, the water flow is buffered, so that the water flow enters the converging chamber e through the first inlet a with a smaller impact force. That is, the water flow enters the converging chamber e with a lower energy state. Since there is a diverting column 131 in the converging chamber e, when the water passes through the diverting column 131, the diverting column 131 can further disperse the water flow, so the impact force of the water flow is further reduced, that is, the energy in the water flow is further reduced. The dual action of the diverting column 131 and the flow restrictor 132 is equivalent to buffering and weakening the energy of the water flow twice, which can more thoroughly control the energy of the water flow, thereby achieving a better anti-splashing effect.

[0181] In some embodiments, the mixing box 12 includes both a diverter column 131 and a flow restrictor 132. The portion of the inner wall surface of the first pipe 1213 near the storage box 11 is closer to the bottom wall 1221 in the direction of the body portion 1215 approaching the bottom wall 1221, and further away from the storage box 11 in the direction of extraction of the storage box 11. In this way, in addition to preventing water splashing, it can further prevent water from splashing onto the weld seam of the storage box 11 and entering the storage box 11, and prevent water from diluting the detergent in the storage box 11.

[0182] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
