Description

Technical Field

[0001] The present application belongs to the field of household appliance technology, and specifically relates to a pulsator washing machine. Background Art

[0002] Pulsator washing machines are a type of washing machine that uses electrical energy to generate mechanical action to wash clothes. They have now entered thousands of households and are very popular. As consumers' living standards improve, their requirements for pulsator washing machines are also getting higher and higher.

[0003] Common pulsator washing machines on the market usually include a housing, an inner barrel arranged inside the housing, an outer barrel, an inner barrel shaft and an installation shell arranged inside the housing, and the pulsator input shaft in the inner barrel shaft is connected to the installation shell through a bearing.

[0004] However, since existing pulsator washing machines have different capacity models, they need to match bearing models of different sizes. The fixed shell sizes corresponding to different bearing models are also different. As a result, when replacing the bearings, the mounting shell needs to be replaced together, which increases costs. Utility Model Content

[0005] The purpose of this application is to provide a pulsator washing machine that can reduce production costs.

[0006] The present application provides a pulsator washing machine, comprising: a casing; an outer barrel, the outer barrel being fixed in the casing, the outer barrel forming a accommodating space with an upper end open to accommodate washing water; an inner barrel, the inner barrel being accommodated in the accommodating space, the inner barrel being rotatably arranged in the accommodating space around an axis in a vertical direction, the interior of the inner barrel being provided with a washing chamber with an upper end open to accommodate clothes; an inner barrel shaft, one end of the inner barrel shaft being connected to the inner barrel, and the other end extending downward through the outer barrel; a bearing being sleeved on the inner barrel shaft, the bearing being located at one end close to the lower side of the inner barrel shaft; a mounting shell being connected to the outer barrel, the mounting shell being provided with a first through hole penetrating in the thickness direction of the mounting shell; a mounting member being detachably arranged in the first through hole, the mounting member being provided with a second through hole, the inner barrel shaft sleeved with the bearing being passed through the second through hole; the bearing being provided in the second through hole.

[0007] The above technical solution has the following advantages or beneficial effects:

[0008] In this solution, the inner barrel shaft with a bearing is inserted into the second through hole of the mounting member, so that the bearing is arranged in the second through hole. The mounting member is connected to the bearing on the inner barrel shaft, which can not only limit the shaking of the inner barrel shaft during the process of driving the inner barrel to rotate, but also can replace the corresponding mounting member when replacing the inner barrel shaft or bearing of different sizes, without replacing the mounting shell, saving the mold opening cost of the mounting shell and effectively reducing the production and preparation cost.

[0009] In an exemplary embodiment of the present application, the mounting member is threadedly connected to the inner wall of the first through hole.

[0010] The above technical solution has the following advantages or beneficial effects:

[0011] The mounting member is threadedly connected to the first through-hole of the mounting housing. Connecting and disconnecting the mounting member and the mounting housing requires only tightening or loosening the threads between the mounting member and the inner wall of the through-hole. This threaded connection between the mounting member and the first through-hole improves installation and removal between the mounting member and the mounting housing, effectively increasing ease of installation and removal.

[0012] In an exemplary embodiment of the present application, the mounting member is snap-connected to the inner wall of the first through hole.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] The mounting member is connected to the first through-hole of the mounting housing by a snap-fit connection. Connecting and disconnecting the mounting member and the housing requires only snapping the mounting member to the inner wall of the first through-hole. This snap-fit connection between the mounting member and the first through-hole improves installation and removal between the mounting member and the housing, effectively increasing ease of installation and removal.

[0015] In an exemplary embodiment of the present application, the mounting member includes:

[0016] a first connecting ring, the first connecting ring being provided with the second through hole, and the first connecting ring being sleeved on the outer side of the bearing;

[0017] The second connecting ring is arranged concentrically with the first connecting ring, and the second connecting ring is arranged on the outside of the first connecting ring and connected to the side of the first connecting ring away from the bearing. The side of the second connecting ring away from the first connecting ring is connected to the inner wall of the first through hole.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] The first connecting ring is sleeved onto the outside of the bearing, while the second connecting ring is concentrically arranged with the first connecting ring. The second connecting ring is positioned outside the first connecting ring and connected to the first connecting ring. The second connecting ring effectively relieves stress exerted on the first connecting ring by the bearing, effectively protecting the mounting member. Furthermore, the second connecting ring is connected to the inner wall of the first through-hole, effectively securing the mounting member to the mounting housing. This further relieves stress on the first connecting ring to the mounting housing, effectively improving the stability of the mounting member.

[0020] In an exemplary embodiment of the present application, the mounting member further comprises:

[0021] Reinforcing ribs, wherein a plurality of the reinforcing ribs are arranged between the first connecting ring and the second connecting ring, and adjacent reinforcing ribs are spaced apart from each other.

[0022] The above technical solution has the following advantages or beneficial effects:

[0023] A plurality of reinforcing ribs are provided between the first connecting ring and the second connecting ring, and adjacent reinforcing ribs are spaced apart from each other. The reinforcing ribs can effectively release the stress borne by the first connecting ring to the second connecting ring, reduce the stress borne by the first connecting ring, improve the stability of the first connecting ring, and thereby improve the stability of the mounting part.

[0024] In an exemplary embodiment of the present application, the mounting housing is made of plastic.

[0025] The above technical solution has the following advantages or beneficial effects:

[0026] The mounting housing is made of plastic, which is lightweight and simplifies the manufacturing process, reducing the production process and complexity. In other words, the use of plastic for the mounting housing can not only reduce the overall weight of the washing machine, but also effectively reduce production costs.

[0027] In an exemplary embodiment of the present application, the mounting housing includes:

[0028] a connecting portion connected to the outer barrel, the connecting portion being provided with a through hole penetrating in a thickness direction of the mounting shell;

[0029] The protrusion is provided at the outer edge of the through hole. The protrusion is a hollow structure. The protrusion is located at the outer edge of the through hole and extends toward a side away from the outer barrel. The first through hole is formed in the protrusion.

[0030] The above technical solution has the following advantages or beneficial effects:

[0031] The mounting housing is connected to the outer barrel via the connecting portion to secure the mounting housing to the bottom wall of the outer barrel, thereby ensuring a tight connection between the mounting housing and the outer barrel. The inner barrel shaft, which is sleeved with a bearing, can be inserted into the first through-hole in the protruding portion through the through-hole on the connecting portion, i.e., a portion of the inner barrel shaft is disposed within the protruding portion, and the protruding portion protects the inner barrel shaft from damage caused by other external forces.

[0032] In an exemplary embodiment of the present application, the mounting housing further includes:

[0033] Reinforcement ribs, wherein a plurality of the reinforcement ribs are sequentially and spaced apart at the connection between the protruding portion and the connecting portion, and are extended along the extension direction of the protruding portion.

[0034] The above technical solution has the following advantages or beneficial effects:

[0035] A plurality of reinforcing ribs are provided at the connection between the protruding portion and the connecting portion, which can effectively improve the strength of the side wall of the mounting shell, improve the stability of the mounting shell, and effectively improve the mechanical performance.

[0036] In an exemplary embodiment of the present application, the pulsator washing machine further includes:

[0037] a pulsator, disposed at the bottom of the washing chamber;

[0038] a pulsator shaft, the pulsator shaft being connected to the pulsator and inserted into the inner barrel shaft;

[0039] The connecting shell is provided with a connecting hole, the inner barrel shaft passes through the connecting hole and is connected to the inner barrel, the connecting shell is connected to the bottom of the outer barrel, and the connecting shell is connected to the mounting shell.

[0040] The above technical solution has the following advantages or beneficial effects:

[0041] The pulsator and its shaft are located within the washing chamber, lifting and lowering clothing for cleaning. The connecting housing's two sides, along its thickness, are connected to the outer tub and the mounting housing, respectively. This ensures the mounting housing is secured to the bottom of the outer tub via the connecting housing, preventing the mounting housing from being directly secured to the bottom of the outer tub. This ensures a tight connection between the mounting housing and the outer tub and prevents the mounting housing from falling off the outer tub.

[0042] In an exemplary embodiment of the present application, the connecting housing is detachably connected to the mounting housing.

[0043] The above technical solution has the following advantages or beneficial effects:

[0044] The connection between the connecting housing and the mounting housing is detachable, that is, the connection and installation of the connecting housing and the mounting housing are more convenient and quick, thereby improving the convenience of connection between the mounting housing and the connecting housing.

[0045] Other features and advantages of the present application will become apparent from the following detailed description, or may be learned in part by practice of the present application.

[0046] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The present invention provides a pulsator washing machine 100. For ease of description, unless otherwise specified, references to up, down, left, right, front, and back herein are based on the state of the pulsator washing machine 100 when in use. The direction facing the user of the pulsator washing machine 100 may be referred to as the front direction, and the direction facing away from the user may be referred to as the back direction.

[0068] In some embodiments of this application, see Figure 1 As shown, the pulsator washing machine 100 may include a housing 110 , which may be a box-shaped structure with a rectangular outer contour. The top and bottom of the housing 110 may be provided with openings, and the interior of the housing 110 may be a hollow structure.

[0069] It is understandable that the box body 110 may also adopt a hollow shell structure of other shapes, such as a circular, elliptical or diamond-shaped hollow shell structure, which is not limited here.

[0070] In some embodiments of this application, see Figure 2 As shown, the pulsator washing machine 100 may further include an outer tub 120. The outer tub 120 may be in the shape of a hollow cylinder or other shapes, such as a sphere. The outer tub 120 may be fixedly mounted within the housing 110 and may include a receiving space with an open top for accommodating wash water.

[0071] In some embodiments of this application, see Figure 3 and Figure 4 As shown, the pulsator washing machine 100 may further include an inner tub 130 for accommodating laundry. The inner tub 130 may have the same shape as the outer tub 120, such as a cylindrical or spherical structure. The inner tub 130 may be disposed within the outer tub 120 and may be rotatably disposed within the accommodating space about a vertical axis, i.e., the inner tub 130 may be rotatably disposed within the outer tub 120. A washing chamber with an open top may be provided within the inner tub 130 for washing and accommodating laundry.

[0072] In some embodiments of the present application, the pulsator washing machine 100 may further include a drainage pipe (not shown in the figure) and a drainage valve (not shown in the figure). The drainage pipe may be connected to the outer barrel 120, and the drainage valve may be arranged on the drainage pipe. When the drainage valve is opened, the water in the inner barrel 130 and the outer barrel 120 may be drained.

[0073] In some embodiments of the present application, the pulsator washing machine 100 may further include a drive device (not shown) to provide driving force. The drive device may be a motor, which may be located at the bottom of the outer tub 120. The motor may have the following structure: the motor may include a rotating portion (rotor) and a fixed portion (stator). The rotating portion may be a housing structure, and the fixed portion may be located inside the rotating portion.

[0074] It should be noted that the driving device may also be a pulley driving structure, which is not limited here.

[0075] In some embodiments of this application, see Figure 4 As shown, the pulsator washing machine 100 may further include an inner barrel shaft 140 for connecting to the inner barrel and driving the inner barrel to rotate. The inner barrel shaft 140 may be a hollow shaft, the upper end of the inner barrel shaft 140 may be connected to the inner barrel 130, and the lower end of the inner barrel shaft 140 may be connected to a driving device. The inner barrel shaft 140 may rotate under the drive of the driving device. The inner barrel shaft 140 may be connected to the inner barrel 130, and during the rotation of the inner barrel shaft 140, the inner barrel 130 may be driven to rotate.

[0076] Among them, the inner barrel shaft 140 can specifically be the following structure: the inner barrel shaft 140 can include an inner barrel input shaft 141, an inner barrel output shaft 142 and a connecting tube 143 fixedly connected between the inner barrel input shaft 141 and the inner barrel output shaft 142, and the inner barrel input shaft 141 can be rotatably connected to the above-mentioned driving device.

[0077] In some embodiments of this application, see Figures 5 to 7 As shown, the pulsator washing machine 100 may further include a mounting housing 150. The mounting housing 150 may be provided at the bottom of the outer tub 120 and connected to the outer tub 120. The mounting housing 150 may have an internal hollow structure to facilitate installation of the above-mentioned connecting cylinder 143 and other structures. The mounting housing 150 may be provided with a first through hole 150a extending through the thickness direction thereof, so that the inner barrel shaft 140 passes through the first through hole 150a to connect with the driving device at the bottom, thereby enabling the driving device to drive the inner barrel shaft 140 to rotate.

[0078] It is understood that the thickness direction of the mounting shell can be a direction perpendicular to the surface of the mounting shell. In some embodiments of the present application, the thickness direction of the mounting shell can be the axis direction of the inner barrel 130.

[0079] In some embodiments of this application, see Figure 6 As shown, the pulsator washing machine 100 may further include a bearing 160 , which may be sleeved on the lower side of the inner barrel shaft 140 and connected to the first through hole 150 a in the mounting shell 150 via the bearing 160 .

[0080] It's understandable that pulsator washing machines 100 come in different capacity models, and the corresponding bearings 160 sizes for these models also vary. Therefore, when installing different bearing 160 models, it's necessary to replace the mounting housing 150 to match the different bearing 160 models. However, replacing a bearing 160 requires replacing a different mounting housing 150, which requires a separate mold to manufacture this mounting housing 150. Designing a separate mold undoubtedly increases manufacturing costs.

[0081] Therefore, in order to reduce the mold opening cost of the mounting housing 150, see Figures 8 to 12 As shown, the pulsator washing machine 100 may further include a mounting member 170 .

[0082] In some embodiments of this application, see Figure 9 and Figure 12 As shown, the mounting member 170 may be an annular structure. The mounting member 170 may be detachably disposed within the first through hole 150a of the mounting housing 150. By detachably mounting the mounting member 170 within the mounting housing 150, the mounting member 170 and the mounting housing 150 may be more conveniently installed and removed.

[0083] In some embodiments of this application, see Figure 9 、 Figure 10 and Figure 12 As shown, the mounting member may be provided with a second through-hole 170a extending therethrough. The axis of the second through-hole 170a may be coaxial with the axis of the first through-hole 150a, so that the inner barrel shaft 140 sleeved with the bearing 160 may be passed through the second through-hole 170a and extended toward a side away from the outer barrel 120. The bearing 160 may be located in the second through-hole 170a. The bearing 160 may reduce the distance between the inner barrel shaft 140 and the inner wall of the second through-hole 170a, thereby limiting the shaking of the inner barrel shaft 140 during the process of the inner barrel shaft 140 driving the inner barrel 130 to rotate.

[0084] It is understandable that when replacing the inner barrel shaft 140 of the washing machine 100 or replacing the bearing 160, the sizes corresponding to different inner barrel shafts 140 and bearings 160 are different, so the apertures of the corresponding second through holes 170a are also different. In order to facilitate the continued location in the first through hole 150a after replacing different bearings 160 or different inner barrel shafts 140, second through holes 170a of different sizes are designed to match bearings 160 of different sizes and inner barrel shafts 140 of different sizes, that is, different mounting parts 170 are designed.

[0085] Then, when replacing the bearing 160 of a different size or replacing the inner barrel shaft 140 of a different size, only the mounting member 170 needs to be replaced without replacing the mounting shell 150 connected to the mounting member 170 .

[0086] It can be understood that since the mounting member 170 is arranged in the first through hole 150a of the mounting shell 150, the overall size of the mounting member 170 is smaller than the size of the mounting shell 150, and the mold size of the mounting member 170 is also smaller than the mold size of the mounting shell 150. Therefore, the mold cost of designing mounting members 170 of different sizes is lower than the mold cost of designing mounting shells of different sizes.

[0087] That is to say, when replacing bearings 160 or inner barrel shafts 140 of different sizes, it is only necessary to replace the mounting member 170 without replacing the mounting shell 150. The replacement cost of the mounting member 170 is lower than the replacement cost of the mounting shell 150, which saves the mold opening cost of the mounting shell and reduces the manufacturing cost of the pulsator washing machine 100.

[0088] In some embodiments of the present application, to facilitate installation and removal of the mounting member 170 and the mounting housing 150, the mounting member 170 may be threadedly connected to the mounting housing 150. The outer wall of the mounting member 170 may be provided with a first thread, and the inner wall of the mounting housing 150 may be provided with a second thread. The first thread of the mounting member 170 corresponds to the second thread on the inner wall of the mounting housing 150, and the mounting member 170 is threadedly connected to the second thread on the mounting housing 150 using the first thread.

[0089] In other embodiments of the present application, the mounting member 170 and the mounting housing 150 can be detachably connected by snapping.

[0090] For example, a buckle is provided on the side wall of the mounting member 170, and a first groove and a second groove are provided on the mounting housing 150, and the first groove and the second groove are connected to each other. During installation, the buckle of the mounting member 170 is inserted into the mounting housing 150 through the first groove. When the mounting member 170 is inserted into the bottom of the first groove, the mounting member 170 is rotated so that the buckle is fixed in the second groove, thereby achieving a buckle connection between the mounting member 170 and the mounting housing 150.

[0091] In some other embodiments of the present application, the mounting member 170 and the mounting shell 150 can also be interference fit, that is, the outer diameter of the mounting member 170 is larger than the inner diameter of the first through hole 150a of the mounting shell 150, so that the mounting member 170 and the mounting shell 150 are interference fit.

[0092] In some other embodiments of the present application, the mounting member 170 and the mounting housing 150 may be connected via a profile.

[0093] In some embodiments of this application, see Figure 9 As shown, the mounting member 170 may include a first connecting ring 171. The first connecting ring 171 may be provided with the second through hole 170a, and the bearing 160 is provided in the second through hole 170a. The side of the bearing 160 away from the inner barrel shaft 140 abuts against the inner wall of the second through hole 170a, so as to limit the shaking of the inner barrel shaft 140 during the process of the inner barrel shaft 140 driving the inner barrel 130 to rotate.

[0094] In some embodiments of this application, see Figure 9 As shown, the mounting member 170 may further include a second connecting ring 172. The second connecting ring 172 may be arranged concentrically with the first connecting ring 171 and larger than the first connecting ring 171. The second connecting ring 172 is disposed outside the first connecting ring 171 and connected to the side of the first connecting ring 171 away from the bearing 160. The outer wall of the second connecting ring 172 may be removably connected to the inner wall of the first through-hole of the mounting housing 150, such as by threaded connection, snap-fit connection, interference fit, etc., as described above.

[0095] The first connecting ring 171 and the second connecting ring 172 can enhance the stability of the mounting member 170 , and can also release stress on the bearing 160 .

[0096] In some embodiments of this application, see Figure 9 As shown, the mounting member 170 may further include a reinforcing rib 173. The reinforcing rib 173 may be provided between the first connecting ring 171 and the second connecting ring 172 to connect the first connecting ring 171 and the second connecting ring 172, and to release stress on the first connecting ring 171 to the second connecting ring 172, thereby reducing the risk of damage to the first connecting ring 171.

[0097] In other embodiments of the present application, the mounting member 170 may further include at least two reinforcing ribs 173 , which are spaced apart in the circumferential direction of the first connecting ring 171 so as to release the stress on the first connecting ring 171 more dispersedly and quickly.

[0098] In some embodiments of this application, see Figure 4 As shown, the pulsator washing machine 100 may further include a connecting housing 180. The connecting housing 180 may be arranged in a manner aligned with the mounting housing 150 and may be secured to the mounting housing 150 using a fixing structure such as screws, bolts, or rivets. The connecting housing 180 may be fixedly connected to the bottom of the outer tub 120, and the mounting housing 150 may be located on a side of the connecting housing 180 away from the outer tub 120.

[0099] It should be noted that the connecting shell 180 and the mounting shell 150 can also be integrally formed.

[0100] In addition, the inner barrel shaft 140 is provided with a connecting portion connected to the inner barrel 130 in the axial direction. This connecting portion can pass through the connecting shell 180 and connect to the bottom of the inner barrel 130 to drive the inner barrel 130 to rotate. The inner barrel shaft 140 is provided with a rotating portion connected to the driving device in the axial direction. The rotating portion can pass through the mounting shell 150 and connect to the driving device, and can drive the inner barrel shaft 140 to rotate under the action of the driving device.

[0101] In some embodiments of this application, see Figure 7 As shown, the mounting housing 150 can be made of plastic material.

[0102] It is understandable that the mounting housing 150 can be made of plastic material, which has a lower overall cost.

[0103] In some embodiments of the present application, the connecting shell 180 may also be made of metal, or other materials, such as alloy, plastic, etc., which are not specifically limited here.

[0104] In some embodiments of the present application, the mounting shell 150 may be made of nylon (PA6) and glass fiber (GF). The mounting shell 150 made of nylon and glass fiber has a lower overall cost.

[0105] It is worth mentioning that the mounting shell 150 may also be made of other plastic materials, which is not specifically limited here.

[0106] In some embodiments of this application, see Figure 10 As shown, the mounting housing 150 may include a connecting portion 151. The connecting portion 151 may be a plate-like structure having a plurality of mounting holes formed thereon, and is connected to the side of the connecting housing 180 away from the outer tub 120 by screws, rivets, or other connection methods. The connecting portion 151 may have a through hole.

[0107] In some embodiments of this application, see Figure 10 As shown, the mounting housing 150 may further include a protrusion 152. The protrusion 152 may be cylindrical and may be a hollow structure. The outer edge of the protrusion 152 is connected to the end surface of the through hole and is protruded toward the side away from the outer barrel 120.

[0108] In some embodiments of the present application, the mounting shell 150 further includes reinforcing ribs 153 , which are plate-shaped structures. The reinforcing ribs 153 are arranged at intervals at the connection between the protrusion 152 and the connecting portion 151 . The reinforcing ribs 153 can improve the comprehensive mechanical properties of the mounting shell 150 .

[0109] For example, by adding reinforcing ribs 153 , the ability of the mounting shell 150 to withstand tension, compression, torsion, impact or alternating stress caused by the rotation of the inner barrel shaft 140 and the bearing 160 can be improved.

[0110] In other embodiments of this application, see Figure 10 As shown, the mounting housing 150 may further include a plurality of reinforcing ribs 153. The reinforcing ribs 153 are plate-shaped structures and are sequentially and spaced apart at the connection between the protruding portion 152 and the connecting portion 151. The reinforcing ribs 153 can improve the comprehensive mechanical properties of the mounting housing 150.

[0111] It is understood that the mounting housing 150 can be made of plastic and have reinforcing ribs 153 provided on the outside of the mounting housing 150 to increase the first-order natural frequency of the mounting housing 150. During high-speed dehydration, the stress experienced by the plastic mounting housing 150 is lower than that experienced by a mounting housing 150 made of sheet metal, resulting in a lower yield strength and a higher safety factor.

[0112] The first-order natural frequency generally refers to the lowest frequency of a structural system's natural vibration at a specific frequency when subjected to external excitation. Specifically, by designing mounting housing 150 as a plastic material, the lowest frequency of mounting housing 150 can be increased, thereby reducing resonance of mounting housing 150 with inner barrel shaft 140 and bearing 160, thereby minimizing damage to mounting housing 150.

[0113] In some embodiments of the present application, the reinforcement rib 153 may extend along the protruding direction of the protrusion 152. However, the length of the reinforcement rib 153 may be less than or equal to the height of the protrusion 152, so as to reduce the stress on the mounting housing 150.

[0114] In some embodiments of this application, see Figure 10 and Figure 11 As shown, the mounting housing 150 may further include a connecting rib 154. The connecting rib 154 may be a strip-shaped structure, which may be vertically disposed on a side of the connecting portion 151 away from the connecting housing 180. The connecting rib 154 may be connected to the bottom of a portion of the reinforcing rib 153 to further reduce the stress on the mounting housing 150.

[0115] In some embodiments of the present application, the mounting housing 150 may include multiple stress dispersing portions (not shown). The multiple stress dispersing portions may be respectively provided at the four corners of the connecting portion 151 , and each stress dispersing portion may be provided with multiple connecting ribs 154 to further reduce the stress on the mounting housing 150 .

[0116] In some embodiments of the present application, the pulsator washing machine 100 may further include a pulsator (not shown). The pulsator may have a fin-shaped structure, is disposed at the bottom of the washing chamber, and is capable of rotating within the washing chamber to drive the clothes within the washing chamber to rotate and flip the clothes.

[0117] In some embodiments of the present application, the pulsator washing machine 100 may further include a pulsator shaft assembly (not shown in the figure), one end of which is located outside the outer barrel 120 and connected to the driving device, and the other end is connected to the pulsator. The pulsator shaft assembly can drive the pulsator to rotate in a clockwise or counterclockwise direction under the drive of the driving device.

[0118] In some embodiments of the present application, the impeller shaft assembly may include an impeller input shaft (not shown in the figure). The impeller input shaft is arranged in the above-mentioned inner barrel input shaft 141 and is connected to the driving device. The impeller input shaft rotates under the drive of the driving device.

[0119] In some embodiments of the present application, the impeller shaft assembly may further include a reducer (not shown in the figure), which is arranged in a accommodating chamber formed by the connecting shell 180 and the mounting shell 150, and one end of the reducer is connected to the impeller input shaft.

[0120] In some embodiments of the present application, the impeller shaft assembly may further include an impeller output shaft (not shown in the figure), one end of which is connected to the side of the reducer away from the impeller input shaft, and the other end of which is fixedly connected to the impeller. It is worth mentioning that, in order to save space, the impeller input shaft is passed through the inner barrel input shaft 141, the impeller output shaft is passed through the inner barrel output shaft 142, and the reducer is arranged in the connecting cylinder 143.

[0121] In addition, the reducer can be a planetary reducer. The reducer can include a sun gear, an outer ring gear, a planet carrier, and planetary gears. The sun gear is connected to the pulsator input shaft; the outer ring gear is fixedly connected to the connecting cylinder 143; the planet carrier is connected to the pulsator output shaft; the planetary gears are rotatably connected to the planet carrier and meshed between the sun gear and the outer ring gear.

[0122] The sun gear can be integrally formed with the impeller input shaft, or can be designed as a separate body, which is not specifically limited here.

[0123] In some embodiments of this application, see Figure 13 As shown, the pulsator washing machine 100 may further include a base 190 , which is disposed at the bottom of the housing 110 . The base 190 is fixedly connected to the housing 110 , and the base 190 is connected to the ground so as to be used to support the housing 110 .

[0124] It should be noted that, in some other embodiments, the box body 110 and the base 190 may also be an integrally formed structure.

[0125] In addition, this base 190 is also used to support the outer barrel 120, the inner barrel 130, the impeller, the driving device, the inner barrel shaft 140, the impeller shaft assembly, the fixed shell 140 and the mounting part 170.

[0126] In some embodiments of this application, see Figure 13 As shown, at least one side of the base 190 is provided with a plurality of ribs 191, which are spaced apart from each other. These ribs 191 can effectively increase the first-order natural frequency, providing a vibration reduction effect, and can also enhance the supporting strength of the side of the base 190, preventing cracking during drop tests and transportation.

[0127] It's understood that the first-order natural frequency generally refers to the lowest frequency of a structural system's natural vibrations at a specific frequency when subjected to external excitation. In other words, ribs 191 can increase the lowest frequency of base 190, thereby reducing resonance with washing machine 100 and minimizing damage to base 190.

[0128] It should be noted that the base 190 may be a square structure, a circle, or other shapes.

[0129] In some embodiments of the present application, the base 190 is a square structure, and the base 190 includes a first side, a second side, a third side, and a fourth side.

[0130] It is worth mentioning that the rib 191 can be provided on three of the first side, the second side, the third side and the fourth side, and the other one can be provided with an opening structure such as a drainage hole.

[0131] In some embodiments of this application, see Figure 13 As shown, the ribs 191 are arranged on the outer edges of the first side, the second side and the third side near the box body 110. The ribs 191 can increase the first-order natural frequency and play a vibration reduction role. The supporting strength of the side of the base 190 can also be strengthened to prevent cracking during drop tests and transportation.
