[0002] A washing machine is a cleaning appliance that uses electric energy to produce mechanical action to clean clothes, providing a lot of convenience for people's life. People's requirements for the neatness of their own clothes are also getting higher and higher. Usually, people often directly introduce water sources such as tap water and well water into the washing machine for washing. The water quality is often hard, containing certain cations such as calcium ions and magnesium ions, which are combined with anions such as acid radicals and sulfate radicals in the water to easily form scale, making the water quality hard, especially in hot water conditions, making the clothes feel hard to the touch, affecting the washing effect.

[0003] In related technologies, a scale inhibition device is usually added to the water inlet channel of the washing machine to soften and filter the water entering the washing tub. However, the existing scale inhibition device is not convenient to disassemble and maintain, and is low in efficiency. CONTENT OF THE UTILITY MODEL

[0074] For the purpose of making the purpose, implementation and advantages of the present application more clear, the following will combine the drawings in the example embodiments of the present application to make a clear and complete description of the example embodiments of the present application. Obviously, the described example embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0075] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, but is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0076] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, the product or equipment including a series of components does not have to be limited to the clearly listed components, but can include other components that are not clearly listed or inherent to these products or equipment.

[0077] In the description of the present application, it needs to be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0078] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0079] In the description of the present application, it needs to be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0080] Although the washing effect is an important indicator to judge the performance of the washing machine, with the gradual improvement of people's requirements for clothes washing, the softness of the clothes after washing becomes crucial. For example, a softener chamber is formed in the soap box of the washing machine to store softener to improve the softness of the clothes.

[0081] Among them, one of the factors that make the clothes hard is the water quality. Therefore, it is crucial to prevent the scale inhibition performance of the washing water during the washing process.

[0082] In the related art, the scale inhibition device is a separate structure arranged on the water inlet path of the washing machine, which not only has a complex structure, but also is inconvenient and low in efficiency for disassembly and maintenance of the scale inhibition device.

[0083] In order to simplify the structure of the scale inhibition device, the present application researchers integrate the scale inhibition device into the soap box assembly. The soap box needs to arrange a detergent chamber and a softener chamber, and a water channel corresponding to each chamber. How to arrange the scale inhibition device to make the structure compact and facilitate the disassembly and maintenance of the scale inhibition device needs in-depth research.

[0084] For the pull-out type soap box assembly, the scale inhibition device is located at the outer end of the soap box assembly, and is exposed when the soap box assembly is pulled open, facilitating disassembly and assembly with high efficiency. The detergent chamber needs to add detergent, and the softener chamber needs to add softener, both of which require convenient operation.

[0085] If the chamber containing the scale inhibition device, the softener chamber and the detergent chamber are arranged in sequence in the direction perpendicular to the pulling direction, although the convenience of operation is improved, the overall length is relatively large, and the water inlet is also relatively long, occupying a large installation space.

[0086] The present application research and development personnel carefully study the structure of the soap box assembly. Since the amount of detergent is large, the chamber of the detergent is large; the softener chamber is small. Therefore, the softener chamber and the chamber containing the scale inhibition device are arranged along the pulling direction, and the chamber containing the scale inhibition device is located outside the softener chamber, facilitating replacement of the scale inhibition device.

[0087] The present application research and development personnel pull the soap box assembly out of the box and install it on the frame of the box, and the scale inhibition device is located at the outer end of the soap box assembly; and the softener chamber can still be exposed after the soap box assembly is pulled open, and the operation is also convenient.

[0088] For the passage of the chamber containing the scale inhibition device, a waterway can be formed separately, but the structure is complex. The present application research and development personnel extend the water inlet passage of the washing water to the chamber containing the scale inhibition device after passing through the detergent chamber, so that the washing water enters the washing drum again through the scale inhibition device. In this way, the amount of water entering the washing drum through the scale inhibition device is large, which is beneficial to improve the scale inhibition effect.

[0089] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0090] For convenience of description, without special indication, the present application is described with reference to the state of the impeller washing machine in use, with the direction facing the user of the washing machine as the front side direction and the direction away from the user as the back side direction; the vertical direction is the up-down direction, and the horizontal direction is the left-right direction. Among them, the left-right direction is shown by the X-axis direction in the drawings, the front-back direction is shown by the Y-axis direction in the drawings, and the vertical direction is shown by the Z-axis direction in the drawings.

[0091] In combination with Figure 1 and Figure 2The pulsator washing machine according to embodiments of the present application comprises a cabinet 10, which serves as the main carrier of the pulsator washing machine and is used for mounting internal washing components, water inlet and discharge components, and for supporting the pulsator washing machine on the ground.

[0092] In order to improve the utilization rate of the space where the pulsator washing machine is located, the cabinet 10 is usually cuboid-shaped, for example, Figure 1 as shown in the middle of the figure.

[0093] The top of the cabinet 10 is provided with a surrounding frame 30, which provides space for the installation of the control device of the pulsator washing machine. The surrounding frame 30 forms a drop opening 31 through which the washing object enters the internal drum for washing.

[0094] The pulsator washing machine further comprises a door cover 20, which is rotatably mounted on the surrounding frame 30 to open or close the drop opening 31.

[0095] In some embodiments, the rear end of the door cover 20 is rotatably connected with the surrounding frame 30, so that the door cover 20 can be rotated upward to open the drop opening 31. The door cover 20 can be rotated downward to close the drop opening 31.

[0096] In some embodiments, the pulsator washing machine further comprises a drum assembly, which is mounted in the cabinet 10. The axial direction of the drum assembly extends along the height direction of the pulsator washing machine to form a pulsator type pulsator washing machine.

[0097] The drum assembly comprises an outer drum, which is mounted in the cabinet 10 and is configured to form a drum for containing washing water, i.e. the internal space of the outer drum is used to hold washing liquid such as water, detergent, softener, etc.

[0098] The drum assembly further comprises an inner drum, which is rotatably mounted in the outer drum. The circumferential wall of the inner drum is provided with a water passage hole, which communicates the outer drum and the inner drum, so that the washing water in the outer drum can enter the inner drum. The washing object such as clothes is placed in the inner drum, and the inner drum rotates relative to the outer drum to realize the washing of the washing object.

[0099] In some embodiments, a driving device such as a driving motor is arranged in the cabinet 10, and the output end of the driving device is in transmission connection with the inner drum. When the driving device is started, it drives the inner drum to rotate relative to the outer drum to realize the washing or dehydration function of the washing object in the inner drum.

[0100] In some embodiments, the inner drum and the outer drum are coaxially arranged, and the drum opening of the inner drum and the drum opening of the outer drum are both directed toward the drop opening 31.

[0101] Continuing to refer to Figure 2 In some embodiments, the pulsator washing machine further comprises a spraying mechanism 500, which can be arranged on the circumferential wall of the drop opening 31 to spray toward the inner drum.

[0102] The water inlet end of the spraying mechanism 500 can be connected to an external water source to supply water for spraying. In some embodiments, the pulsator washing machine comprises a first water inlet mechanism 400, one of the ports of the first water inlet mechanism 400 is connected to the spraying mechanism 500 to supply water for spraying.

[0103] The spraying end of the spraying mechanism 500 can be exposed to the circumferential side wall of the dropping opening 31 to spray towards the inner drum. In some embodiments, a second mounting opening 33 is provided on the surrounding frame 30 to enable the spraying end of the spraying mechanism 500 to be fixed to be exposed to the circumferential side wall of the dropping opening 31 through the second mounting opening 33.

[0104] In some embodiments, in combination with Figure 3 The spraying mechanism 500 comprises a spraying pipe 510, one end of the spraying pipe 510 is connected to one of the ports of the first water inlet mechanism 400 to guide the water of the first water inlet mechanism 400 to the spraying end.

[0105] The spraying mechanism 500 further comprises a spraying head 520, the spraying head 520 is fixed to the end of the spraying pipe 510 away from the first water inlet mechanism 400, and at least part of the spraying head 520 is exposed to the dropping opening 31 through the second mounting opening 33. In this way, the water of the first water inlet mechanism 400 is sprayed from the spraying head 520 towards the inner drum through the spraying pipe 510, and the spraying area is larger than simply water inlet, which can expand the wetting range of the external water source on the clothes to quickly wet the clothes and improve the washing efficiency of the clothes.

[0106] In some embodiments, the first water inlet mechanism 400 is provided with a control valve to control whether the external water source enters the spraying pipe 510, i.e. whether the spraying mechanism 500 is started.

[0107] For example, before the washing program is started, the external water source first sprays the clothes in the inner drum through the spraying mechanism 500 to play a pre-washing role to quickly wet the clothes, and when the mixture of the detergent and water enters the inner drum, the detergent quickly spreads inside the wet clothes to improve the mixing effect of the detergent and improve the washing effect.

[0108] In some embodiments, as Figure 2 For example, the surrounding frame 30 is provided with a first mounting opening 32, and part of the soap box assembly 40 is fixed in the surrounding frame 30 through the first mounting opening 32. Another part of the soap box assembly 40 is exposed to the first mounting opening 32, so that at least part of the soap box assembly 40 can be exposed through the first mounting opening 32 to facilitate the addition of detergent and softener.

[0109] For example, the surrounding frame 30 is provided with a first mounting opening 32, and part of the soap box assembly 40 is fixed in the surrounding frame 30 through the first mounting opening 32. Another part of the soap box assembly 40 is exposed to the first mounting opening 32, so that at least part of the soap box assembly 40 can be exposed through the first mounting opening 32 to facilitate the addition of detergent and softener.

[0110] In some embodiments, the first installation port 32 is located at the rear side of the dispensing port 31, which facilitates the communication between the soap box assembly 40 and the water inlet structure.

[0111] The external water source can enter the soap box assembly 40 and carry the detergent or softener into the drum assembly, while achieving water addition to the drum assembly.

[0112] The soap box assembly 40 can be connected to the first water inlet mechanism 400, and the external water source enters the soap box assembly 40 through the first water inlet mechanism 400 and enters the inner drum through different water channels in the soap box assembly 40 by controlling the first water inlet mechanism 400.

[0113] Exemplarily, the first water inlet mechanism 400 is located at the side of the soap box assembly 40 along the left-right direction, which not only makes the connection between the soap box assembly 40 and the first water inlet mechanism 400 compact, but also facilitates the first water inlet mechanism 400 to supply water to the spraying mechanism 500 without affecting the water inlet of the soap box assembly 40 towards the inner drum.

[0114] In combination Figure 3 In some embodiments, the soap box assembly comprises a water inlet box 100 fixed to the surrounding frame 30, and the fixing methods include but are not limited to screw connection, clamping, etc.

[0115] In combination Figure 4 The water inlet box 100 is configured to form an installation cavity 101 for accommodating the dispensing box 200. The water inlet box 100 is also configured to form a pull-out port 102 in communication with the installation cavity 101.

[0116] In some embodiments, the pull-out port 102 is oriented towards the dispensing port 31, which facilitates front and rear pulling and improves the convenience of pulling operation.

[0117] As Figure 3 and Figure 4 shown, the soap box assembly further comprises a dispensing box 200 for accommodating detergents and softeners, etc. The dispensing box 200 is push-pullably installed in the installation cavity 101 through the pull-out port 102, and the dispensing box 200 and the water inlet box 100 jointly enclose a water inlet channel 103.

[0118] When at least part of the dispensing box 200 is pulled out through the pull-out port 102, the chamber in the dispensing box 200 is exposed to facilitate the user to add detergents and softeners; and then the dispensing box 200 is pushed into the installation cavity 101.

[0119] The water inlet box 100 is connected to the first water inlet mechanism 400, and the external water source enters the water inlet box 100 through the first water inlet mechanism 400, then enters the dispensing box 200, and then enters the inner drum through the water inlet channel 103.

[0120] The arrangement of the chambers in the dispensing box 200 in some embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0121] In combination Figure 4 The dispensing box 200 is configured to form a first chamber 210 for storing detergent.

[0122] The first chamber 210 has a top opening; when at least part of the dispensing box 200 is pulled out of the installation cavity 101 through the pull-out opening 102, at least part of the first chamber 210 is exposed, which facilitates the user to add detergent into the first chamber 210 through the top opening.

[0123] The first chamber 210 is in communication with the water inlet channel 103, so that the mixture of detergent and water in the first chamber 210 can enter the inner drum through the water inlet channel 103.

[0124] In some embodiments, the first chamber 210 is provided with a first siphon structure 270, and the first chamber 210 is in communication with the water inlet channel 103 through the first siphon structure 270. When water flows into the first chamber 210, the mixture of water and detergent triggers siphon action and enters the water inlet channel 103, which can reduce the residual detergent in the first chamber 210 and produce odor.

[0125] In some embodiments, the first chamber 210 is further provided with a rotating impeller 260, which is rotatably installed in the first chamber 210 to rotate relative to the first chamber 210, thereby mixing the detergent and water.

[0126] The dispensing box 200 is also configured to form a second chamber 220 for storing softener. The second chamber 220 is independent of the first chamber 210, that is, the second chamber 220 and the first chamber 210 are not in communication, and the water in the second chamber 220 and the water in the first chamber 210 do not mix.

[0127] In some embodiments, the volume of the first chamber 210 is greater than the volume of the second chamber 220, so that more detergent can be accommodated.

[0128] The second chamber 220 has a top opening; when at least part of the dispensing box 200 is pulled out of the installation cavity 101 through the pull-out opening 102, at least part of the second chamber 220 is exposed, which facilitates the user to add softener into the second chamber 220 through the top opening.

[0129] The second chamber 220 is in communication with the water inlet channel 103, so that the mixture of softener and water in the second chamber 220 can enter the inner drum through the water inlet channel 103.

[0130] In some embodiments, a second siphon structure 280 is arranged in the second chamber 220, and the second chamber 220 is in communication with the water inlet channel 103 through the second siphon structure 280. When the water flow enters the second chamber 220, the mixture of the water flow and the softener triggers the siphon effect and enters the water inlet channel 103, which can reduce the residual softener in the second chamber 220 and produce odor.

[0131] The dispensing box 200 is also configured to form a third chamber 230, and a scale inhibition device 300 is arranged in the third chamber 230.

[0132] The scale inhibition device 300 is filled with scale inhibition material. The scale inhibition material can be a solid substance, for example, in the form of particles. The volume of the scale inhibition material is greater than the size of the filter hole of the scale inhibition device 300, so that the scale inhibition material cannot pass through the filter hole and exit the scale inhibition device 300.

[0133] For example, the scale inhibition material can be a ceramic particle slow-release active water material that generates a strong negative charge, adsorbs positively charged metal ions such as calcium and magnesium in water, and makes calcium and magnesium heavy metal ions stably exist in water in a dissolved state, thereby improving the activity of water and the scale inhibition performance of water.

[0134] The scale inhibition device 300 is detachably installed in the third chamber 230. When the dispensing box 200 is pulled out of the water inlet box 100, the scale inhibition device 300 can be easily replaced and maintained without the need to disassemble the dispensing box 200, and the replacement and maintenance of the scale inhibition device 300 are simple, convenient, and efficient.

[0135] In combination Figure 5 In some embodiments, the scale inhibition device 300 includes a shell and scale inhibition material arranged in the shell. The shell is installed in the mounting groove 231 of the third chamber 230.

[0136] In some embodiments, the shell is a cube, and the shell has six surfaces. The six surfaces of the shell are each provided with a through hole 301, so that the water flow can enter the shell and contact the scale inhibition material and then flow out.

[0137] In some embodiments, the scale inhibition device 300 includes a first shell part 310 and a second shell part 320, and the first shell part 310 and the second shell part 320 are detachably connected to jointly enclose a space for accommodating the scale inhibition material.

[0138] For example, the first shell part 310 is provided with a buckle 311, and the second shell part 320 is provided with a buckle hole 321. The buckle 311 and the buckle hole 321 are buckled to achieve the buckling of the first shell part 310 and the second shell part 320.

[0139] A plurality of through holes 301 are arranged on the first shell part 310 and the second shell part 320, so that the water flows into the shell interior, contacts the scale inhibition material, and then flows out.

[0140] The pore size of the through holes 301 is smaller than the particle size of the scale inhibition material, and the through holes 301 are configured to allow the water to flow through while preventing the scale inhibition material from falling.

[0141] The third chamber 230 is open at the top, and when at least part of the dispensing box 200 is pulled out of the installation cavity 101 through the pull-out opening 102, the scale inhibition device 300 in the third chamber 230 is exposed, so that the user can conveniently replace and maintain the scale inhibition device 300 in the third chamber 230.

[0142] The third chamber 230 is in communication with the water inlet channel 103, so that the water entering the third chamber 230 passes through the scale inhibition device 300 and then enters the water inlet channel 103. The scale inhibition material plays a role in preventing scale formation, reduces the scale formed on the clothes, and improves the softness of the clothes.

[0143] In some embodiments, the third chamber 230 and the second chamber 220 are located on the same side of the first chamber 210, and in some embodiments, the third chamber 230 and the second chamber 220 are located on the side of the first chamber 210 away from the first water inlet mechanism 400, so that the arrangement space of the first water inlet mechanism 400 is sufficient.

[0144] In some embodiments, along the pulling direction of the dispensing box 200, the third chamber 230 is close to the outer end of the dispensing box 200. The outer end of the dispensing box 200 is the pulling end, and the inner end of the dispensing box 200 is located in the installation cavity 101. Exemplarily, the third chamber 230 is located on the outer side of the second chamber 220.

[0145] In this way, when at least part of the dispensing box 200 is pulled out of the installation cavity 101 through the pull-out opening 102, it can be ensured that the third chamber 230 can be completely exposed, facilitating the disassembly and assembly of the scale inhibition device 300, and improving the convenience of replacing and maintaining the scale inhibition device 300. Along the pulling direction of the dispensing box 200, the side of the dispensing box 200 pulled out of the installation cavity 101 is the outer side, and the side of the dispensing box 200 pushed into the installation cavity 101 is the inner side.

[0146] In this way, the first chamber 210 with a larger volume is arranged on one side, the second chamber 220 and the third chamber 230 are arranged side by side along the pulling direction and located on the same side of the first chamber 210, so that the structure of the dispensing box 200 is compact; moreover, at least part of the first chamber 210 extends to the outer side of the dispensing box 200, facilitating the user to add more detergent; although the second chamber 220 is arranged on the back side of the third chamber 230, at least part of the second chamber 220 can still be exposed when the dispensing box 200 is pulled out, so that the user can add a softener.

[0147] Of course, in some embodiments, the third chamber 230 can be in communication with the first chamber 210, so that water entering the first chamber 210 can enter the third chamber 230 at the same time, and then the water entering the first chamber 210 from the external water source mixes with the detergent, and then carries the scale inhibiting substance through the scale inhibiting device 300 into the inner drum. In this way, the detergent, water and scale inhibiting substance are mixed in the soap box assembly 40, which is conducive to simplifying the water channel arrangement in the water inlet box 100.

[0148] In some embodiments of the present application, the third chamber 230 is independent of the first chamber 210 and the second chamber 220, so that water entering the first chamber 210 cannot enter the third chamber 230, and water entering the second chamber 220 cannot enter the third chamber 230, thereby avoiding the influence of the detergent and the softener on the scale inhibiting device 300.

[0149] In some embodiments of the present application, the water inlet box 100 is configured to allow water to enter the first chamber 210 and the third chamber 230 at the same time, that is, water enters the first chamber 210 and the third chamber 230 at the same time, so that the amount of water entering the third chamber 230 can be ensured to be large, and the scale inhibiting effect can be improved.

[0150] The water inlet box 100 is also configured to allow water to enter the second chamber 220 alone, so that the mixed liquid of the softener and water can enter the inner drum to soften the clothes.

[0151] The arrangement of the water channel in the water inlet box 100 in some embodiments of the present application will be described in detail below with reference to the drawings.

[0152] In combination Figure 4 In some embodiments, the water inlet box 100 includes a first box body 110, the first box body 110 is configured to form a mounting cavity 101, and the first box body 110 and the dispensing box 200 jointly define a water inlet channel 103.

[0153] The first box body 110 includes a top plate 111, a bottom plate, a back plate and two side plates, the top plate 111 and the bottom plate are vertically opposite and have a spacing, the two side plates are arranged between the top plate 111 and the bottom plate and are respectively located on the left and right sides of the top plate 111 and the bottom plate, and the back plate is arranged at the back side of the top plate 111, the bottom plate and the two side plates, so that the top plate 111, the bottom plate, the back plate and the two side plates jointly enclose the mounting cavity 101 with the front side forming the pull-out opening 102.

[0154] The water inlet box 100 further includes a box cover 120, the box cover 120 is fixedly connected with the first box body 110 and jointly defines a water channel.

[0155] In combination Figure 4 And Figure 6The water inlet box 100 is configured to form a second channel 104 having a first end and a second end along the water flow direction, and the water flows from the second end to the first end of the second channel 104. The first end of the second channel 104 is in communication with the first chamber 210. The second end of the second channel 104 is configured to connect to an external water source.

[0156] In some embodiments, the water inlet box 100 is configured to form a second channel 104 having a first end and a second end along the water flow direction, and the water flows from the second end to the first end of the second channel 104. The first end of the second channel 104 is in communication with the first chamber 210. The second end of the second channel 104 is configured to connect to an external water source. Figure 6 and Figure 7 In some embodiments, the water inlet box 100 is configured to form a second channel 104 having a first end and a second end along the water flow direction, and the water flows from the second end to the first end of the second channel 104. The first end of the second channel 104 is in communication with the first chamber 210. The second end of the second channel 104 is configured to connect to an external water source.

[0157] The portion of the second channel 104 downstream of the first water passage 1041 extends to the top of the first chamber 210. The bottom wall of the second channel 104 extending to the top of the first chamber 210 is provided with a first spray hole 1042, which is in communication with the second channel 104 and the first chamber 210.

[0158] The first spray hole 1042 can be located on the side of the first chamber 210 away from the rotating impeller 260, for example, above the first siphon structure 270. In this way, the first spray hole 1042 is used to mix the detergent and water away from the rotating impeller 260, thereby improving the uniformity and dissolution efficiency of the detergent and water mixture.

[0159] The first spray hole 1042 is configured to be inclined backward, which can also impact the back wall of the first chamber 210, thereby reducing the detergent, especially the washing powder, from sticking to the wall.

[0160] In some embodiments, the first spray hole 1042 can be provided with multiple first spray holes 1042, and the multiple first spray holes 1042 are arranged at intervals along the extension direction of the second channel 104 to improve the spray effect on the detergent in the first chamber 210.

[0161] In some embodiments of the present application, the second end of the second channel 104 is in communication with the first water inlet mechanism 400 to connect the external water source to the second channel 104.

[0162] In some embodiments, the first water inlet mechanism 400 has a first valve port 410, a second valve port 420, and a third valve port 430, which are respectively configured to communicate with different water channels of the water inlet box 100.

[0163] In some embodiments, the first valve port 410, the second valve port 420 and the third valve port 430 are arranged side by side along a preset direction, for example, the first valve port 410, the second valve port 420 and the third valve port 430 are arranged side by side along a front-rear direction, so as to facilitate communication with the water passage and facilitate valve control.

[0164] The second valve port 420 communicates with the spray pipe 510, so that external water passes through the second valve port 420 and the spray pipe 510 and is sprayed into the inner cylinder through the spray head 520.

[0165] The third valve port 430 communicates with the second end of the second passage 104 to pass external water into the second passage 104.

[0166] The first water inlet mechanism 400 includes a control valve 440 for controlling the opening and closing of the first valve port 410, the second valve port 420 and the third valve port 430, thereby controlling the water passage through which external water can selectively enter.

[0167] For example, when the control valve 440 controls the third valve port 430 to open and the second valve port 420 and the first valve port 410 to close, external water enters the first chamber 210 through the first valve port 410 and the second passage 104, and after mixing with the detergent, enters the inner cylinder through the water inlet passage 103.

[0168] For another example, when the control valve 440 controls the second valve port 420 to open and the first valve port 410 and the third valve port 430 to close, external water passes through the second valve port 420 and the spray pipe 510 and is sprayed into the inner cylinder through the spray head 520.

[0169] Continuing to refer to Figure 4 and Figure 6 , the water inlet box 100 is also configured to form a fifth passage 105 having a first end and a second end along the water flow direction, the water flow flowing from the second end to the first end of the fifth passage 105. The first end of the fifth passage 105 communicates with the second chamber 220, so that water can enter the second chamber 220 and mix with the softener. The second end of the fifth passage 105 is used to connect an external water source.

[0170] In some embodiments, the first end of the fifth passage 105 extends above the second chamber 220, and a third water inlet port 1051 is formed on the bottom wall of the fifth passage 105, the third water inlet port 1051 communicating the second chamber 220 and the fifth passage 105, the water in the fifth passage 105 entering the second chamber 220 through the third water inlet port 1051, mixing with the softener in the second chamber 220, and then entering the water inlet passage 103 through the second siphon structure 280.

[0171] In some embodiments, a plurality of third water inlets 1051 are provided, and the plurality of third water inlets 1051 are arranged in a rectangular matrix on the bottom wall of the fifth channel 105 to form a larger spraying area and improve the mixing effect of the softener and water.

[0172] In some embodiments, the diameter of the third water inlet 1051 gradually increases along the direction of water flow, so that the water pressure is higher when the water first reaches the third water inlet 1051, and as the water flows forward, the water pressure decreases, but the diameter of the third water inlet 1051 increases. This can improve the uniformity of water intake into multiple third water inlets 1051, thereby improving the uniformity of mixing softener and water.

[0173] In some embodiments, a recess is formed on the bottom wall of the fifth channel 105. The third water inlet 1051 is disposed in the recess to facilitate draining water in the fifth channel 105 into the second chamber 220, thereby reducing water accumulation on the bottom wall of the fifth channel 105.

[0174] Illustratively, a V-shaped groove structure is formed on the bottom wall of the fifth channel 105 , and the width of the V-shaped groove gradually decreases from top to bottom, and the third water inlet 1051 extends to the bottom area of ​​the V-shaped groove.

[0175] In some embodiments, a second spray hole 1052 is further provided on the bottom wall of the fifth channel 105 , and the second spray hole 1052 connects the second chamber 220 and the fifth channel 105 .

[0176] The second spray hole 1052 can be located above the second siphon structure 280. This allows the second spray hole 1052 to mix the softener and water in the rear area of ​​the second chamber 220, improving the uniformity of the mixing. Furthermore, the second spray hole 1052 is configured to be tilted rearward, impacting the rear wall of the second chamber 220 and reducing the likelihood of softener adhering to the rear wall.

[0177] A plurality of second spray holes 1052 may be provided, and the plurality of second spray holes 1052 are spaced apart in the left-right direction to improve the spraying effect of the water flow on the softener in the second chamber 220 .

[0178] In some embodiments of the present application, the second end of the fifth channel 105 is connected to the first valve port 410 of the first water inlet mechanism 400, and external water enters the fifth channel 105 through the first valve port 410 and enters the second chamber 220 through the third water inlet 1051 and the second spray hole 1052.

[0179] In some embodiments, the water inlet box 100 is further configured to form a first channel 106 . The first channel 106 has a first end and a second end along the direction of water flow. Water flows from the second end to the first end of the first channel 106 .

[0180] The first end of the first channel 106 is in communication with the third chamber 230, and the second end of the first channel 106 is configured to be in communication with an external water source. The external water source can enter the third chamber 230 through the first channel 106.

[0181] In some embodiments, the second end of the first channel 106 is in communication with one of the ports of the first water inlet mechanism 400, so as to be in communication with the external water source. In this way, the opening and closing of the first channel 106 can be controlled independently.

[0182] In some embodiments, the second end of the first channel 106 is in communication with the second channel 104, so that part of the water in the second channel 104 enters the third chamber 230 through the first channel 106. In this way, no additional valve is needed to control the opening and closing of the first channel 106, and the first channel 106 is filled with water when the second channel 104 is filled with water, which can simplify the channel structure on the water inlet box 100 and ensure that the first channel 106 has a large amount of water, thereby ensuring the scale inhibition effect.

[0183] In order to reduce the influence of the water in the second channel 104 on the water flow in the second channel 104 entering the first chamber 210 and impacting the rotating impeller 260, the connection end of the first channel 106 and the second channel 104 is located downstream of the first spray hole 1042.

[0184] In some embodiments, in combination with Figure 6 The first end of the first channel 106 extends to the top of the third chamber 230, and a water passing hole 1061 is arranged on the bottom wall of the first channel 106 to communicate the first channel 106 and the third chamber 230. The water passing hole 1061 can be a circular hole, an elliptical hole, a polygonal hole, etc.

[0185] The water passing hole 1061 is arranged in an array on the bottom wall of the first channel 106, so as to increase the water passing area and improve the speed of the water flow in the first channel 106 entering the third chamber 230.

[0186] For example, the plurality of water passing holes 1061 are arranged in an array along the pulling direction, and the plurality of water passing holes 1061 are arranged in an array along a direction perpendicular to the pulling direction.

[0187] For example, two water passing holes 1061 are arranged in an array along the pulling direction (corresponding to the Y-axis direction in the drawing), and three water passing holes 1061 are arranged in an array along a direction perpendicular to the pulling direction (corresponding to the X-axis direction in the drawing).

[0188] In some embodiments, the first channel 106 includes a first sub-channel 1062 and a second sub-channel 1063, the first sub-channel 1062 is located above the third chamber 230, and the second sub-channel 1063 is configured to communicate the first sub-channel 1062 and an external water source.

[0189] The second channel 104 is provided with a first spray hole 1042 located at the rear of the dispensing box 200, and the first sub-channel 1062 is located above the third chamber 230, so that the first sub-channel 1062 is located at the front of the dispensing box 200, and the second sub-channel 1063 drains water from the rear to the front. The water passing hole 1061 is provided on the first sub-channel 1062.

[0190] A groove structure 1064 is formed on the bottom wall of the first sub-channel 1062, and the water passing hole 1061 extends to the bottom wall of the groove structure 1064, so as to avoid water accumulation on the flat bottom wall. By forming the groove structure 1064, water on the bottom wall of the first sub-channel 1062 can be drained as much as possible, reducing the possibility of odor caused by water accumulation.

[0191] The groove structure 1064 can include a plurality of grooves extending in the pulling direction, such as V-shaped grooves, and the plurality of grooves are arranged side by side in a direction perpendicular to the pulling direction. This arrangement can improve the uniformity of water flow entering the third chamber 230 from the bottom wall of the first sub-channel 1062.

[0192] Continuing to refer to Figure 6 and Figure 7 In some embodiments, the water inlet box 100 can also be configured to form a third channel 107, the third channel 107 has a first end and a second end along the water flow direction, and the water flow flows from the second end to the first end of the third channel 107. The first end of the third channel 107 communicates with the first chamber 210. The second end of the third channel 107 is configured to connect an external water source.

[0193] The third channel 107 is provided with a second water passing hole 1071, and the dispensing box 200 is formed with a second water inlet 213, the second water inlet 213 is arranged symmetrically with the first water inlet 212 about the rotating impeller 260. The second water inlet 213 is arranged opposite to the second water passing hole 1071, and the water of the second water passing hole 1071 enters the first chamber 210 through the second water inlet 213, and the water flow impacts the rotating impeller 260 to rotate to mix water and detergent.

[0194] The part of the third channel 107 downstream of the second water passing hole 1071 extends to the top of the first chamber 210, and the third channel 107 is provided with a third spray hole 1072 on the bottom wall of the third channel 107, and the third spray hole 1072 communicates the third channel 107 and the second chamber 220.

[0195] The third spray hole 1072 can be located on the side of the first chamber 210 away from the rotating impeller 260, for example, the third spray hole 1072 is located above the first siphon structure 270. In this way, the third spray hole 1072 is used to mix the detergent and water away from the rotating impeller 260, which improves the uniformity and dissolution efficiency of the mixed detergent and water. Moreover, the third spray hole 1072 is configured to be inclined backward, which can also impact the rear wall of the first chamber 210, reducing the detergent, especially the wall-hanging laundry detergent.

[0196] In some embodiments, the third spray hole 1072 can be provided in plurality, and the plurality of third spray holes 1072 are arranged at intervals along the extension direction of the third channel 107, to improve the spraying effect of the detergent in the first chamber 210.

[0197] The water temperature of the third channel 107 is higher than that of the second channel 104. For example, the water in the third channel 107 can be hot water, for example, water heated by a water heater; the water of the second channel 104 can be cold water, for example, tap water.

[0198] In some embodiments, the impeller washing machine can further include a second water inlet mechanism 600 for supplying water to the third channel 107, and the second water inlet mechanism 600 can provide hot water. For example, the water inlet end of the second water inlet mechanism 600 is in communication with a hot water supply component, and the water outlet end of the second water inlet mechanism 600 is in communication with the third channel 107, so that the impeller washing machine can use hot water for washing to improve the washing effect.

[0199] In some embodiments, the water inlet box 100 can also be configured to form a fourth channel (not shown in the drawings), the first end of the fourth channel is in communication with the first end of the third channel 107, and the second end of the fourth channel is in communication with the third chamber 230. In this way, when hot water enters the first chamber 210, the water in the third channel 107 enters the third chamber 230 through the fourth channel and contacts the scale inhibition device 300 in the third chamber 230, carrying the scale inhibition molecules dissolved in the water into the water inlet channel 103, improving the scale inhibition performance of the washing water.

[0200] For example, in the Figure 6 , the end of the third channel 107 provided with the third spray hole 1072 continues to extend to the top of the third chamber 230, that is, to form a fourth channel.

[0201] The embodiments of the present application provide the possibility for the impeller washing machine to use different water temperatures for washing by providing the third channel 107, and the water in the third channel 107 can still enter the inner drum through the scale inhibition device 300 by providing the fourth channel to communicate the third channel 107 and the third chamber 230, ensuring the scale inhibition performance of the washing water.

[0202] In some embodiments, the top plate 111 of the first box body 110 is formed with protruding partition bars to separate and form the second channel 104 , the fifth channel 105 , the first channel 106 , the third channel 107 and the fourth channel.

[0203] Combine Figure 6 , describing the water flow direction of each water channel in some embodiments of the present application.

[0204] When the laundry processing device is in the washing state, the external water source enters the first water inlet mechanism 400, the control valve 440 controls the third valve port 430 to open, and the first valve port 410 and the second valve port 420 to close; Figure 6 Water flows through the third valve port 430 into the second channel 104. Some of the water flows through the first water inlet 1041 into the intermediate flow channel 211, and then into the first chamber 210 through the first water inlet 212. The water impacts the rotating impeller 260, causing it to rotate and mix the water and detergent. Some of the water flows through the first water inlet 1041 and then sprays the first chamber 210 through the first spray holes 1042. The resulting mixture of water and detergent flows through the first siphon structure 270 into the water inlet channel 103 and then into the inner drum.

[0205] Part of the water flows through the first spray hole 1042 into the first channel 106, and then enters the third chamber 230 through the water hole 1061. Figure 6 The external water passes through the scale inhibition device 300 and carries the scale inhibition molecules dissolved in the water by the scale inhibition material into the water inlet channel 103, and then enters the inner cylinder to play a role in scale inhibition.

[0206] When the clothing treatment device is in the care state, the external water source enters the first water inlet mechanism 400, the control valve 440 controls the first valve port 410 to open, and the third valve port 430 and the second valve port 420 to close; Figure 6 Midpoint arrows. External water enters the fifth channel 105 through the first valve port 410 . Some water enters the second chamber 220 through the third water inlet 1051 . Some water sprays the second chamber 220 through the second spray hole 1052 . The water and softener mix, then enter the water inlet channel 103 through the second siphon structure 280 , and then enter the inner drum.

[0207] When the clothes processing device uses hot water for washing, the external water source enters the second water inlet mechanism 600 and then enters the third channel 107. Figure 6The middle dotted arrow. Part of the water in the third channel 107 enters the first chamber 210 through the second water outlet 1071 and the second water inlet 213, and the water flow impacts the rotating impeller 260 to rotate to mix the water and the detergent; part of the water flow flows through the second water outlet 1071 and is sprayed into the first chamber 210 through the third spray hole 1072. The mixed solution of water and detergent enters the water inlet channel 103 through the first siphon structure 270, and then enters the inner cylinder.

[0208] In this process, part of the water flow flows through the third spray hole 1072 into the fourth channel, and then enters the third chamber 230. The water flows through the scale inhibition device 300 to carry the scale inhibition molecules dissolved in the water into the water inlet channel 103, and then into the inner cylinder, thereby playing a scale inhibition role.

[0209] Of course, in some possible implementations, the second valve port 420 of the first water inlet mechanism 400 and the second water inlet mechanism 600 are opened at the same time, the third channel 107 and the second channel 104 simultaneously supply water to the first chamber 210, and the first channel 106 and the fourth channel simultaneously supply water to the third chamber 230. At this time, the pulsator washing machine can use warm water for washing.

[0210] Referring to Figure 7 In some embodiments, the third chamber 230 is provided with two first side walls 2311 which are opposite and have a spacing. For example, the two first side walls 2311 are opposite and have a spacing along the X-axis direction. Figure 7

[0211] The two first side walls 2311 are provided with a limiting rib 2312 on the side facing each other, and the scale inhibition device 300 is in contact with the limiting rib 2312 to play a limiting role on the scale inhibition device 300. The limiting rib 2312 can also play a role in improving the structural strength of the first side wall 2311.

[0212] In some embodiments, the limiting rib 2312 is provided with a plurality of limiting ribs 2312 which are arranged in a spacing along the front-rear direction of the first side wall 2311 to improve the limiting role.

[0213] The present embodiment plays a limiting role on the position of the scale inhibition device 300 in the horizontal plane by providing the limiting rib 2312 on the first side wall 2311, reduces the possibility of the scale inhibition device 300 moving in the installation groove 231, so that the scale inhibition device 300 can be directly placed in the installation groove 231 to achieve position limitation, without the need for additional fixing structure, thereby simplifying the structure of the third chamber 230.

[0214] In combination Figure 8 In some embodiments, the third chamber 230 is provided with a bottom wall which is located at the bottom end of the two first side walls 2311. The bottom wall and the two first side walls 2311 form the installation groove 231.​

[0215] The third chamber 230 is provided with two second side walls opposite to each other and spaced apart, and connected to two ends of the two first side walls respectively. The two second side walls are located on the bottom wall, so that the two first side walls 2311, the bottom wall and the two second side walls form an installation groove 231 which is a groove opening upward. The two second side walls and the two first side walls 2311 jointly limit the position of the scale inhibition device 300 in the plane of the bottom wall.

[0216] The bottom wall is provided with a first water outlet 232; when the dispensing box 200 is installed in the water inlet box 100, the bottom wall of the dispensing box 200 forms the top wall of the water inlet channel 103, so that the first water outlet 232 communicates the third chamber 230 and the water inlet channel 103, so that the water in the third chamber 230 can enter the water inlet channel 103 through the installation groove 231.

[0217] The scale inhibition device 300 can be detachably installed in the installation groove 231, and the shape of the installation groove 231 matches the scale inhibition device 300, so that the position of the scale inhibition device 300 in the horizontal plane can be limited by the shape of the installation groove 231, without the need for additional fixing structure, i.e. the scale inhibition device 300 can be directly placed in the installation groove 231, which is simple and convenient to disassemble and assemble, further improving the convenience of disassembly and replacement of the scale inhibition device 300 and improving the replacement efficiency.

[0218] It should be noted that the first water outlet 232 can be a larger water outlet to ensure the water outlet rate and reduce the possibility of water overflowing outward when the water flow in the third chamber 230 is too large. At this time, the area of the first water outlet 232 is smaller than the area of the bottom wall of the installation groove 231, so that the bottom wall of the installation groove 231 can still support the scale inhibition device 300, avoiding the possibility of the scale inhibition device 300 being exposed downward from the first water outlet 232. Of course, the first water outlet 232 can also be formed by arranging a plurality of smaller openings in an array.

[0219] Continuing to refer to Figure 7 In some embodiments, the third chamber 230 includes a first cavity wall 233 and two second cavity walls 234 close to the second chamber 220; the top of the first cavity wall 233 is connected to the cavity wall of the second chamber 220; and there is a space between the bottom of the first cavity wall 233 and the cavity wall of the second chamber 220 in the pulling direction of the dispensing box. The bottom of the first cavity wall 233 is provided with a second water outlet 235 to increase the water outlet area of the third chamber 230 and reduce the possibility of water overflowing outside the third chamber 230.

[0220] Two second cavity walls 234 are located on the side of the first cavity wall 233 away from the second cavity 220, and are spaced apart along a first direction intersecting the pulling direction of the dropping box, and perpendicular to the height direction of the pulsator washing machine. For example, the first direction can be Figure 7 in the X-axis direction.

[0221] In some embodiments, the first side wall 2311 is located on the inner side of the second cavity wall 234, and functions to limit the scale inhibition device 300, and the second cavity wall 234 is used to construct the third cavity 230.

[0222] The two second cavity walls 234 are provided with a second water outlet 235, further increasing the water outlet area of the third cavity 230 and reducing the possibility of water overflowing outside the third cavity 230.

[0223] Referring to Figure 8 In some embodiments, the third cavity 230 further includes a third cavity wall 237 opposite to the first cavity wall 233 along the pulling direction of the dropping box 200 and having a spacing, and the third cavity wall 237 is not provided with a water outlet, so as to avoid water in the third cavity 230 from overflowing from the handle of the dropping box 200.

[0224] Continuing to refer to Figure 8 In some embodiments, a rib plate 236 is arranged between the bottom of the first cavity wall 233 and the cavity wall of the second cavity 220, so as to improve the structural strength of the third cavity 230 and the second cavity 220.

[0225] In some embodiments, the dropping box 200 includes a second box body 240, which is used to construct the first cavity 210, the second cavity 220 and the third cavity 230.

[0226] The dropping box 200 further includes a pulling part 250 arranged on the front side of the second box body 240. The pulling part 250 is an operation part for pushing and pulling the dropping box 200, and can have various structures. For example, the pulling part 250 has a handle structure; for another example, the pulling part 250 has a plate shape, and has a spacing along the front-rear direction between the pulling part 250 and the second box body 240. The pulling part 250 and the front wall of the second box body 240 form a downwardly open groove, which is convenient for a user to put his hand into, so as to pull out the dropping box 200 from the water inlet box 100. The plate-shaped pulling part 250 makes the dropping box 200 have a good appearance, and the opening of the groove is hidden on the inner side of the pulling part 250, without affecting the appearance.

[0227] In some embodiments, the second box body 240 is provided with sliding structures on both sides along the left and right directions. The sliding structures can be slidably installed in the water inlet box 100. The sliding structures extend along the pulling direction to guide the pulling and sliding of the delivery box 200.

[0228] In some embodiments, there is a gap between the front wall of the first chamber 210 and the front wall of the second box body 240, and a connecting rib 214 is provided between the front wall of the first chamber 210 and the front wall of the second box body 240 to improve the structural strength of the first chamber 210.

[0229] Exemplarily, a plurality of connecting ribs 214 are provided, and the plurality of connecting ribs 214 are spaced apart along the left-right direction to further improve the structural strength of the first chamber 210 .

[0230] The connecting ribs 214 may extend to the bottom wall of the first chamber 210 to further improve the structural strength of the first chamber 210 .

[0231] In some embodiments, combined Figure 9 and Figure 10 At least part of the hole wall of the water hole 1061a near the second chamber 220 is tilted so that the water flow of the water hole 1061a deviates from the second chamber 220 and tilts into the third chamber 230, reducing the possibility of water entering the third chamber 230 splashing into the second chamber 220.

[0232] Exemplarily, the water hole 1061a is tilted toward a portion of the side wall of the second chamber 220 , and the cross-sectional area of ​​the water hole 1061a gradually decreases from top to bottom, so that the water flows away from the second chamber 220 and tilts into the third chamber 230 .

[0233] In some embodiments, some of the water holes on the bottom wall of the third chamber 230 extend vertically, for example, the water holes 1061 a , so that the water flow can directly impact the anti-scaling device 300 .

[0234] In some embodiments, some of the water holes on the bottom wall of the third chamber 230 are curved holes, such as water hole 1061b. Water hole 1061b includes a first hole portion extending vertically and a second hole portion extending horizontally, the second hole portion communicating with the first hole portion. The first hole portion communicates with the first channel 106, and the second hole portion, at an end facing away from the first hole portion, communicates with the third chamber 230. The second hole portion faces the third chamber wall 237 of the third chamber 230, allowing water hole 1061b to spray water toward the third chamber wall 237. The water, confined by the third chamber wall 237, is then sprayed toward the scale inhibitor 300, thereby allowing the water to flow through the scale inhibitor 300.

[0235] Continue to refer to Figure 9The bottom plate 112 of the water inlet box is inclined, and the front end of the bottom plate 112 is inclined downward, so that the bottom wall of the water inlet channel 103 is inclined downward, facilitating the water in the water inlet channel 103 to flow forward into the inner cylinder, reducing the accumulation of water in the water inlet channel 103 and being prone to bacteria.

[0236] As shown in Figure 9 The second siphon structure 280 includes a second siphon pipe 281 arranged on the bottom wall of the second chamber 220. The top end of the second siphon pipe 281 communicates with the second chamber 220, and the bottom end of the second siphon pipe 281 communicates with the water inlet channel 103.

[0237] The second siphon structure 280 further includes a second siphon cap 282 sleeved outside the second siphon pipe 281. The bottom end of the second siphon cap 282 is spaced from the bottom wall of the second chamber 220, and the second siphon cap 282 has a gap with the pipe wall forming the second siphon pipe 281. In this way, when water flows into the second chamber 220, the liquid level between the second siphon cap 282 and the second siphon pipe 281 rises until it is higher than the top end of the second siphon pipe 281. The mixture of the softener and water in the second chamber 220 flows out of the water inlet channel 103 through the top end of the second siphon pipe 281. At this time, the siphon phenomenon begins to occur, and the mixture is continuously sucked out of the second chamber 220 and into the water inlet channel 103.

[0238] In order to ensure that the mixture in the second chamber 220 is discharged as much as possible, the bottom wall of the second chamber 220 is inclined towards the second siphon pipe 281, so that the second siphon pipe 281 is arranged at the lowest part of the bottom wall of the second chamber 220.

[0239] Referring to Figure 11 and Figure 12 The bottom wall of the first chamber 210 is provided with a rotating shaft 261, so that the rotating impeller 260 is rotatably mounted on the rotating shaft 261. The rotating shaft 261 can extend vertically, so that the rotating impeller 260 has a larger stirring area.

[0240] In some embodiments, the rotating impeller 260 includes a shaft sleeve 262 sleeved on the rotating shaft 261. The top end of the shaft sleeve 262 is provided with a limiting structure to limit the contact between the rotating impeller 260 and the bottom wall of the first chamber 210.

[0241] In some embodiments, the top end of the shaft sleeve 262 is closed to form a top cover, and the top cover forms the limiting structure.

[0242] The top cover has a large contact area with the top of the rotating shaft 261, which increases the rotational resistance of the rotating impeller 260 relative to the rotating shaft 261.

[0243] To this end, in some embodiments, the top cover is provided with a support rib 265, which is in contact with the top end of the rotating shaft 261, so that the rotating impeller 260 is suspended outside the rotating shaft 261, and the contact area between the rotating shaft 261 and the shaft sleeve 262 can be reduced, which is conducive to reducing the rotation resistance of the rotating impeller 260 relative to the rotating shaft 261

[0244] In some embodiments, the rotating impeller 260 further comprises a plurality of blades 263, which are arranged outside the shaft sleeve 262 and are spaced apart around the circumference of the shaft sleeve 262. When the first water inlet 212 or the second water inlet 213 is filled with water towards the first chamber 210, the water flow impacts the blades 263, so that the rotating impeller 260 rotates as a whole relative to the rotating shaft 261, and the blades 263 drive the detergent to mix with the water.

[0245] In some embodiments, the plurality of blades 263 are uniformly spaced apart around the circumference of the shaft sleeve 262, which ensures the uniformity of the circumferential force of the rotating impeller 260.

[0246] When there is more liquid in the first chamber 210, the rotating impeller 260 may be in contact with the top wall of the first chamber 210 due to the buoyancy, and the impact between the rotating impeller 260 and the top wall of the first chamber 210 is likely to produce an abnormal sound, and the impact between the blades 263 and the top wall of the first chamber 210 may even cause damage.

[0247] In some embodiments, the top of the shaft sleeve 262 is provided with a protrusion 264, and the cross-sectional area of the protrusion 264 is smaller than that of the shaft sleeve 262. For example, the protrusion 264 is a tapered column, and the cross-sectional area of the tapered column is smaller than that of the shaft sleeve 262.

[0248] By such arrangement, the blades 263 and the top wall of the first chamber 210 can have a spacing therebetween, which reduces the possibility of collision between the blades 263 and the top wall of the first chamber 210. Moreover, the cross-sectional area of the protrusion 264 is smaller than that of the shaft sleeve 262, so that the contact area between the protrusion 264 and the top wall of the first chamber 210 is small, and the frictional resistance is small, which reduces the rotation resistance of the rotating impeller 260 and makes the rotating impeller 260 rotate more smoothly.

[0249] In some embodiments, the top end of the protrusion 264 is higher than the top end of the blades 263, which can further reduce the possibility of collision between the blades 263 and the top wall of the first chamber 210.

[0250] In some embodiments, a first spacing is defined between the top of the protrusion 264 and the top wall of the first chamber 210 along the axial direction of the rotating impeller 260. The first spacing may range from 1 mm to 3 mm, for example, from 1 mm to 1.5 mm, or from 1.5 mm to 2.0 mm, or from 2.0 mm to 2.5 mm, or from 2.5 mm to 3.0 mm. This ensures a certain spacing between the protrusions 264, reserving space for the rotating impeller 260 to move upward, while also preventing the spacing from being too large, which would increase the overall height of the soap box assembly.

[0251] In some embodiments, a second gap is defined between the bottom end of the sleeve 262 and the bottom wall of the first chamber 210 along the axial direction of the rotating impeller 260. The second gap ranges from 2 mm to 4 mm. For example, the first gap ranges from 2.0 mm to 2.5 mm, or from 2.5 mm to 3.0 mm, from 3.0 mm to 3.5 mm, or from 3.5 mm to 4.0 mm. This arrangement ensures that there is a gap between the rotating impeller 260 and the bottom wall of the first chamber 210.

[0252] like Figure 12 As shown, the first siphon structure 270 includes a first siphon pipe 271 disposed on the bottom wall of the first chamber 210 . The top end of the first siphon pipe 271 communicates with the first chamber 210 , and the bottom end of the first siphon pipe 271 communicates with the water inlet channel 103 .

[0253] The first siphon structure 270 also includes a first siphon cap 272, which is sleeved on the outside of the first siphon tube 271. There is a gap between the bottom end of the first siphon cap 272 and the bottom wall of the first chamber 210, and there is a gap between the first siphon cap 272 and the tube wall forming the first siphon tube 271. In this way, when water enters the first chamber 210, the liquid level between the first siphon cap 272 and the first siphon tube 271 rises until it is higher than the top of the first siphon tube 271. The mixture of softener and water in the first chamber 210 flows out to the water inlet channel 103 through the top of the first siphon tube 271. At this time, the siphon phenomenon begins to make a sound, and the mixture is continuously sucked out of the first chamber 210 and enters the water inlet channel 103.

[0254] In order to ensure that the mixed liquid in the first chamber 210 is drained as completely as possible, the bottom wall of the first chamber 210 is tilted toward the first siphon tube 271 so that the first siphon tube 271 is located at the lowest point of the bottom wall of the first chamber 210 .

[0255] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
