Technical Field

[0002] The present application relates to the technical field of household appliances, and in particular to a pulsator washing machine. Background Art

[0003] With the development of society and the acceleration of urbanization, washing machines have become indispensable household appliances. Although some washing machines are currently equipped with filters, these filters are not ideal. They are less efficient in collecting light, non-sinking hair and lint, reducing the cleaning efficiency of knitted fabrics and affecting their cleanliness and aesthetics after washing. Utility Model Content

[0004] The purpose of the present application is to solve the problem that hair and lint that are light and difficult to sink cannot be effectively collected and other problems.

[0005] The present application provides a pulsator washing machine, comprising:

[0006] Box;

[0007] The outer cylinder is arranged in the box body, and a water storage cavity is formed in the outer cylinder;

[0008] The inner drum is arranged in the water holding cavity and can rotate relative to the outer drum, and a washing cavity is formed in the inner drum, and the washing cavity is used to hold clothes;

[0009] The impeller is rotatably arranged at the bottom of the inner cylinder;

[0010] A driving device, connected to the impeller, for driving the impeller to rotate in a first direction and a second direction; and

[0011] The filter device is arranged in the washing chamber, and the filter device includes:

[0012] The diversion bracket includes:

[0013] The bracket body is connected to the wall of the inner tube, and the bracket body includes a first water inlet;

[0014] a first flow-guiding portion connected to the bracket body, the first flow-guiding portion comprising a first flow-guiding surface facing away from the cylinder wall of the inner cylinder;

[0015] Filter box, the filter box includes:

[0016] The box body is detachably connected to the bracket body, and the box body includes a first outer surface facing the bracket body;

[0017] A filter cavity is formed in the box body;

[0018] a first filter inlet, disposed on a first outer surface of the box body and communicating with the filter cavity;

[0019] The filter chamber outlet is provided on the box body and is communicated with the filter chamber and the washing chamber respectively;

[0020] A filter screen is arranged at the outlet of the filter chamber;

[0021] The first guide portion includes a first end and a second end distributed along the circumference of the inner cylinder, the first end is arranged close to the cylinder wall of the inner cylinder, and the second end is arranged close to the first filter inlet and is flush with the first outer surface of the box body or has a second preset distance, so that the washing water passing through the first guide portion can enter the filter cavity through the first filter inlet under the action of inertia.

[0022] In this manner, a filter device is provided within a pulsator washing machine. The filter device has a first water inlet on its side, which connects to the washing chamber along the circumference of the inner drum. Wash water flowing along the circumference of the inner drum can enter the filter device through the first water inlet, meaning that the wash water can enter the filter device through the side of the filter device. This eliminates the need for hair to sink to the bottom of the washing chamber; wash water can enter the filter device through the first water inlet simply by flowing along the inner drum wall, thereby improving the filter device's filtration efficiency for lightweight, non-sinking hair and lint. The second end of the first flow guide is flush with the plane of the first outer surface forming the first filter inlet, ensuring that the first flow guide does not extend into the first filter inlet and occupy space therein, thereby ensuring a high flow rate of wash water entering the filter device. The second end of the first flow guide is spaced a second predetermined distance L4 from the first outer surface, ensuring that the first flow guide does not extend into the first filter inlet and occupy space therein, thereby ensuring a high flow rate of wash water entering the filter device. On the other hand, although there is a certain distance between the first guide part and the first outer surface, the washing water flowing along the first guide part can continue to flow along the guide direction under the Coanda effect or inertia and enter the first filter inlet, ensuring the guide effect of the first guide part and taking into account the guide effect and water intake.

[0023] The present application also provides a pulsator washing machine, comprising:

[0024] Box;

[0025] The outer cylinder is arranged in the box body, and a water storage cavity is formed in the outer cylinder;

[0026] The inner drum is arranged in the water holding cavity and can rotate relative to the outer drum, and a washing cavity is formed in the inner drum, and the washing cavity is used to hold clothes;

[0027] The impeller is rotatably arranged at the bottom of the inner cylinder;

[0028] A driving device, connected to the impeller, for driving the impeller to rotate in a first direction and a second direction; and

[0029] The filter device is arranged in the washing chamber, and the filter device includes:

[0030] The diversion bracket includes:

[0031] The bracket body is connected to the wall of the inner tube, and the bracket body includes a first water inlet;

[0032] a first flow-guiding portion connected to the bracket body, the first flow-guiding portion comprising a first flow-guiding surface facing away from the cylinder wall of the inner cylinder;

[0033] Filter box, the filter box includes:

[0034] The box body is detachably connected to the bracket body, and the box body includes a first outer surface facing the bracket body;

[0035] A filter cavity is formed in the box body;

[0036] a first filter inlet, disposed on a first outer surface of the box body and communicating with the filter cavity;

[0037] The filter chamber outlet is provided on the box body and is communicated with the filter chamber and the washing chamber respectively;

[0038] A filter screen is arranged at the outlet of the filter chamber;

[0039] At least a portion of the first guide portion is arranged between the first water inlet and the first filter inlet. The first guide portion is configured to guide the washing water flowing circumferentially along the cylinder wall of the inner drum in the washing chamber from the first water inlet to one end of the first outer surface close to the first filter inlet when the impeller rotates in the first direction, and allow the washing water to enter the filter chamber through the first filter inlet under the action of inertia.

[0040] In this manner, a filter device is provided within a pulsator washing machine. The filter device has a first water inlet on its side, which connects to the washing chamber along the circumference of the inner drum. Wash water flowing along the circumference of the inner drum can enter the filter device through the first water inlet, meaning that the wash water can enter the filter device through the side of the filter device. This eliminates the need for hair to sink to the bottom of the washing chamber; instead, wash water can flow along the inner drum wall and enter the filter device through the first water inlet, thereby improving the filter device's filtration efficiency for lightweight, non-sinking hair and lint. A first guide directs wash water entering from the first water inlet toward a first outer surface, which is provided with a first filter inlet. The first guide directs water toward the end of the first outer surface where the first filter inlet is formed. Water can enter the filter chamber through the first filter inlet due to the Coanda effect or inertia, ensuring the first guide's effective flow guidance and, therefore, the filter device's filtration efficiency.

[0041] In some embodiments of the present application, a second preset distance L4 between the second end of the first guide portion and the first outer surface satisfies: L4<5 mm.

[0042] In this way, the distance between the second end of the first guide part and the first outer surface is not easy to be too large. If the second preset distance L4 is too large, the washing water flowing along the first guide part may flow to the second guide part and flow out from the second water inlet, and cannot enter the first filter inlet, thereby affecting the guide effect of the first guide part.

[0043] The present application also provides a pulsator washing machine, comprising:

[0044] Box;

[0045] The outer cylinder is arranged in the box body, and a water storage cavity is formed in the outer cylinder;

[0046] The inner drum is arranged in the water holding cavity and can rotate relative to the outer drum, and a washing cavity is formed in the inner drum, and the washing cavity is used to hold clothes;

[0047] The impeller is rotatably arranged at the bottom of the inner cylinder;

[0048] A driving device, connected to the impeller, for driving the impeller to rotate in a first direction and a second direction; and

[0049] The filter device is arranged in the washing chamber, and the filter device includes:

[0050] The diversion bracket includes:

[0051] The bracket body is connected to the wall of the inner tube, and the bracket body includes a first water inlet;

[0052] a first flow-guiding portion connected to the bracket body, the first flow-guiding portion comprising a first flow-guiding surface facing away from the cylinder wall of the inner cylinder;

[0053] Filter box, the filter box includes:

[0054] The box body is detachably connected to the bracket body, and the box body includes a first outer surface facing the bracket body;

[0055] A filter cavity is formed in the box body;

[0056] a first filter inlet, disposed on a first outer surface of the box body and communicating with the filter cavity;

[0057] The filter chamber outlet is provided on the box body and is communicated with the filter chamber and the washing chamber respectively;

[0058] A filter screen is arranged at the outlet of the filter chamber;

[0059] The first guide surface includes:

[0060] a second guide section, the second guide section being arranged between the first water inlet and the first filter inlet, for guiding the wash water entering the bracket body through the first water inlet toward a direction away from the wall of the inner drum and toward the center of the inner drum to the first filter inlet when the pulsator rotates in the first direction;

[0061] The second flow guiding section is configured as a concave arc surface, the first outer surface is configured as a convex arc surface, and a first flow guiding channel is formed between the second flow guiding section and the first outer surface of the box body.

[0062] Thus, a filter device is provided within a pulsator washing machine. The filter device has a first water inlet on its side, which is circumferentially connected to the washing chamber along the inner drum. Washing water flowing along the circumference of the inner drum can enter the filter device through the first water inlet, that is, the washing water can enter the filter device through the side of the filter device. This eliminates the need for hair to sink to the bottom of the washing chamber; washing water can enter the filter device through the first water inlet simply by flowing along the inner drum wall, thereby improving the filter device's filtering effectiveness against lightweight, non-sinking hair and lint. The first outer surface is a convex curved surface, while the second guide section is a concave curved surface. The first guide channel formed by the second guide section and the first outer surface reduces resistance to the flow of washing water, allowing the washing water to maintain a uniform velocity during flow, reducing the formation of vortices and turbulence caused by uneven water velocity, thereby ensuring the diversion efficiency of the first guide channel.

[0063] In some embodiments of the present application, the second guide section is a concave arc surface.

[0064] In this way, the second guide section is constructed as a concave arc surface. When the washing water flows through the concave arc surface, the washing water will flow along the concave arc surface, so that the washing water forms a Coanda effect during the flow.

[0065] In some embodiments of the present application, the arc angle θ of the second guide segment satisfies: θ<42°.

[0066] In this way, when θ is less than 42°, the second guide section can be ensured to be a relatively flat and continuous curved surface, and the washing water can more easily form a Coanda effect on the second guide section, and also reduce the adverse conditions such as water flow dispersion, vortex formation or change of flow direction caused by the large curvature of the second guide section.

[0067] In some embodiments of the present application, the arc angle θ of the second guide segment satisfies: θ>29°.

[0068] In this way, when θ>29°, the length of the second guide section can be appropriately reduced to avoid the second guide section being too flat and prolonging the time for the washing water to flow on the second guide section. The second guide section has a suitable curvature to improve the diversion efficiency. The washing water can flow quickly through the second guide section and flow into the first filter inlet, thereby improving the filtration efficiency of the filtration device.

[0069] In some embodiments of the present application, the box body includes:

[0070] A first shell is provided on a side of the first flow guide portion away from the cylinder wall of the inner cylinder, and a first filter inlet is formed in the first shell;

[0071] The second shell is connected to a side of the first shell away from the first air guide portion. The second shell and the first shell define a filter cavity, and an outlet of the filter cavity is formed in the second shell.

[0072] In this way, the first shell and the second shell can be a split structure, so that when the filter box is removed from the bracket body, the first shell can be separated from the second shell, thereby conveniently removing hair and lint collected in the filter cavity.

[0073] In some embodiments of the present application, the first housing further includes:

[0074] The baffle portion has a first end connected to the edge of the first filter inlet and a second end extending toward the second shell.

[0075] In this way, the washing water flowing in from the first filter inlet can be blocked by the flow blocking portion to prevent the washing water from flowing back from the first filter inlet, thereby ensuring the filtering effect of the filtering device.

[0076] In some embodiments of the present application, the first filter inlet comprises:

[0077] a first edge extending along the axial direction of the inner tube;

[0078] a second edge, the second edge extending along the axial direction of the inner tube, and the second edge and the first edge being opposite to each other along the circumferential direction of the inner tube;

[0079] The baffle includes:

[0080] a first baffle wall, wherein a first end of the first baffle wall is connected to the first edge;

[0081] a second baffle wall, wherein a first end of the second baffle wall is connected to the second edge, and the first baffle wall and the second baffle wall are opposite to each other along the circumference of the inner tube;

[0082] Along the circumference of the inner tube, the second baffle wall is away from the first end of the first guide surface relative to the first baffle wall, the second end of the second baffle wall is located on the extension surface of the first guide surface, or the second end of the second baffle wall is away from the extension surface of the first guide surface along the direction away from the first baffle wall.

[0083] In this way, the second baffle wall extends a certain length toward the second housing to prevent backflow of wash water. However, the end of the second baffle wall closest to the second housing is located on an extension of the first guide surface. In other words, the second baffle wall does not block the wash water flowing along the first guide surface. The wash water can continue to flow into the filter cavity along the guiding direction of the first guide surface, thereby preventing turbulence of the wash water when entering the filter box and within the filter box, which would reduce the filtering effect.

[0084] In some embodiments of the present application, along the arrangement direction of the first shell and the second shell, the baffle has a first preset length L1, the filter cavity has a second preset length L2, and L1 and L2 satisfy: L1 / L2<1 / 2.

[0085] In this way, L1 and L2 satisfy: L1 / L2<1 / 2, which can ensure that the flow blocking portion does not extend too much into the filter cavity and occupy the effective filter area of ​​the filter cavity.

[0086] In some embodiments of the present application, along the arrangement direction of the first shell and the second shell, the baffle has a first preset length L1, the filter cavity has a second preset length L2, and L1 and L2 satisfy: L1 / L2>1 / 3.

[0087] In this way, L1 and L2 satisfy the following relationship: L1 / L2>1 / 3, which ensures that the baffle has a certain length to ensure that the baffle can achieve the anti-backflow effect. If the baffle is too short, it will not only fail to achieve the purpose of anti-backflow, but also fail to stop hair and lint in the filter cavity, and the hair and lint will easily flow out of the first filter inlet.

[0088] In some embodiments of the present application, along the arrangement direction of the first shell and the second shell, there is a first preset distance L3 between the second end of the baffle and the second shell, and the filter cavity has a second preset length L2, and L3 and L2 satisfy: L3 / L2<2 / 3.

[0089] In this way, L3 / L2 is less than 2 / 3 to prevent the distance between the second end of the baffle and the second shell from being too large. If the ratio of the distance between the second end of the baffle and the second shell to the filter cavity is too large, that is, if the distance between the second end of the baffle and the second shell is too long, the baffle's backflow prevention effect will be affected, and wash water will be more likely to flow out of the first filter inlet through the distance between the second end of the baffle and the second shell. Hair and lint will also be more likely to flow out of the filter cavity through the distance between the second end of the baffle and the second shell.

[0090] In some embodiments of the present application, along the arrangement direction of the first shell and the second shell, there is a first preset distance L3 between the second end of the baffle and the second shell, and the filter cavity has a second preset length L2, and L3 and L2 satisfy: L3 / L2>1 / 2.

[0091] In this way, L3 / L2>1 / 2 to prevent the distance between the flow blocking portion and the second housing from being too short. Because the second housing is provided with a filter cavity outlet, if the ratio of the distance between the second end of the flow blocking portion and the second housing to the filter cavity is too small, that is, if the distance between the second end of the flow blocking portion and the second housing is too short, the flow blocking portion may block the path between the first filter inlet and the filter cavity outlet. In other words, the flow blocking portion may block the path for wash water to flow out of the filter cavity, thereby affecting the filtering effect of the filter device.

[0092] In some embodiments of the present application, the box body further includes: a wire hanging post, one end of which is disposed in one of the first shell or the second shell, and a second end of which extends toward the other of the first shell or the second shell.

[0093] In this way, the hanging post utilizes the characteristic that common impurities such as dander and hair in the washing process are easily entangled, and the dander and hair entering the filter cavity during washing can be entangled on the hanging post to reduce the backflow of hair through the first filter inlet.

[0094] In some embodiments of the present application, the second shell is movably connected to the first shell to open or close the filter cavity.

[0095] In some embodiments of the present application, the bracket body further includes a second water inlet, and the second water inlet and the first water inlet are distributed on both sides of the bracket body along the circumference of the inner cylinder;

[0096] In this way, when the second shell moves relative to the first shell, the filter cavity can be opened or closed, so that hair, hair debris, etc. in the filter box can be cleaned conveniently.

[0097] The filter device also includes:

[0098] a second flow guide portion formed on the bracket body, the second flow guide portion and the first flow guide portion being arranged along the circumference of the inner tube, the second flow guide portion including a second flow guide surface facing away from the tube wall of the inner tube, the first end of the second flow guide surface being closer to the second water inlet than the second end of the second flow guide surface, and the second end of the second flow guide surface being closer to the first filter inlet than the first end of the second flow guide surface;

[0099] The second guide surface is configured to guide the washing water entering the bracket body through the second water inlet to the first filter inlet in a direction away from the wall of the inner drum and close to the center of the inner drum when the impeller rotates along the second direction.

[0100] In some embodiments of the present application, the bracket body further includes a second water inlet, and the second water inlet and the first water inlet are distributed on both sides of the bracket body along the circumference of the inner cylinder;

[0101] In this way, no matter whether the impeller rotates along the first direction or the second direction, the first guide part and the second guide part can guide the washing water, so that the washing water can be guided to the first filter inlet of the filter box regardless of whether it flows along the first direction or the second direction, to ensure that the filter device filters the washing water.

[0102] The filter device also includes:

[0103] The second guide portion is connected to the bracket body, and the second guide portion and the first guide portion are arranged along the circumference of the inner tube. The second guide portion includes a second guide surface facing the box body, and the first end of the second guide surface is closer to the second water inlet and close to the cylinder wall of the inner tube than the second end of the second guide surface. The second end of the second guide surface is closer to the first filter inlet than the first end of the second guide surface. The second end of the second guide surface is closer to the center of the inner tube than the first end of the second guide surface.

[0104] In this way, no matter whether the impeller rotates along the first direction or the second direction, the first guide part and the second guide part can guide the washing water, so that the washing water can be guided to the first filter inlet of the filter box regardless of whether it flows along the first direction or the second direction, to ensure that the filter device filters the washing water.

[0105] In some embodiments of the present application, the second end of the first guide surface and the second end of the second guide surface are connected to each other and form an angular portion at the connection.

[0106] In this way, when the washing water flows along the first guide surface, the washing water flows along the first guide surface to the corner portion, and it is not easy for the washing water to flow through the corner portion to the second guide surface. Instead, it will continue to flow along the guide direction of the first guide surface based on the Coanda effect to enter the first filter inlet, thereby ensuring that the filtration efficiency of the filtration device is improved.

[0107] In some embodiments of the present application, the second end of the first guide surface and the second end of the second guide surface are connected to each other and form a connecting line at the connection point, and the connecting line extends along the axial direction of the inner cylinder.

[0108] In this way, the connection between the first and second guide surfaces forms a connecting line that extends axially along the inner drum, equivalent to forming a peak structure at the connection between the first and second guide surfaces. Wash water flows along the first guide surface to the peak structure, but is unlikely to pass through the peak structure to flow to the second guide surface. Instead, it continues to flow along the guiding direction of the first guide surface due to the Coanda effect to enter the first filter inlet, thereby ensuring improved filtration efficiency of the filter device.

[0109] In some embodiments of the present application, the filter cavity outlet comprises:

[0110] a first filter outlet;

[0111] The second filter outlet, the second filter outlet and the first filter outlet are arranged at intervals along the circumference of the inner cylinder, the first filter outlet corresponds to the first guide surface along the radial direction of the inner cylinder, the second filter outlet corresponds to the second guide surface along the radial direction of the inner cylinder, the second filter outlet is located in the guide direction of the first guide surface, and the second filter outlet is located in the guide direction of the first guide surface.

[0112] In this way, the washing water can continue to maintain its original flow direction after entering the filter box from the first water inlet, and flow out of the filter cavity through the second filter outlet along the flow direction, and the washing water is not likely to form turbulence in the filter cavity.

[0113] In some embodiments of the present application, an extension of the first guide surface passes through the second filter outlet. When the pulsator rotates in the first direction, the first guide surface is used to allow wash water flowing circumferentially along the wall of the inner drum to pass through the first guide surface and the first filter inlet into the filter cavity and then flow out of the filter cavity through the second filter outlet.

[0114] The extended surface of the second guide surface passes through the first filter outlet. When the impeller rotates in the second direction, the second guide surface is used to allow the washing water flowing circumferentially along the wall of the inner drum to pass through the second guide surface and the first filter inlet into the filter cavity, and flow out of the filter cavity from the first filter outlet.

[0115] In this way, the washing water guided by the first guide surface or the second guide surface can flow out of the filter chamber smoothly along the original flow path, and the flow direction of the washing water is not easy to change, thereby reducing the turbulence of the washing water in the filter chamber, and further reducing the backflow of the washing water due to the chaotic flow direction, thereby improving the filtering effect of the filter device.

[0116] In some embodiments of the present application, the flow guide bracket further includes:

[0117] A through port is formed at the bottom of the support body and communicates with the washing chamber;

[0118] The filter box also includes:

[0119] The second filter inlet is connected to the through port. The second filter inlet is formed in the filter box and faces the impeller. The second filter inlet connects the washing chamber and the filter chamber along the axial direction of the inner cylinder, so that when the impeller rotates, the washing water flowing upward along the cylinder wall of the inner cylinder enters the filter chamber through the bottom water inlet and the second filter inlet.

[0120] In this way, the filtering device provided in the embodiment of the present application can not only filter out light impurities such as hair and dander that easily float on the upper layer of the washing water through the path of the first water inlet, the second water inlet and the first filter inlet, but can also filter out general dander that is relatively heavy and easily sinks to the bottom of the washing chamber through the path of the through port and the second filter inlet, so that the filtering device has a more comprehensive filtering capability.

[0121] In some embodiments of the present application, the box body includes:

[0122] The first barrier is arranged in the filter cavity to separate the filter cavity into a first filter cavity and a second filter cavity arranged along the axial direction of the inner cylinder. The first filter inlet is connected to the first filter cavity, and the second filter inlet is connected to the second filter cavity.

[0123] In this way, the washing water entering from the first water inlet and the second water inlet from the circumference of the inner drum and guided to the first filter inlet by the first guide part and the second guide part can be isolated from the washing water entering the second filter inlet from the bottom of the washing chamber to avoid the confluence of two washing waters flowing in different directions and the generation of turbulence in the filter chamber.

[0124] In some embodiments of the present application, at least one second barrier is disposed in the first filter cavity to separate the first filter cavity into at least two sub-filter cavities, and the at least two sub-filter cavities are arranged along the axial direction of the inner cylinder.

[0125] In this way, hair and lint can be distributed relatively evenly in multiple sub-filter chambers or deposited on each second baffle to avoid excessive concentration of hair and lint at the bottom of the filter chamber and clogging the filter net at the bottom of the filter chamber, thereby affecting the filtering effect of the filter device.

[0126] In some embodiments of the present application, the box body further includes:

[0127] A water retaining member, one end of which is provided on the box body, and the water retaining member is located at the second filter inlet. The water retaining member is an elastic water retaining member, and the water retaining member can be deformed under the action of the washing water entering from the second filter inlet to open the second filter inlet;

[0128] The limiting member is fixed to the box body and is located on a side of the water retaining member away from the second filter cavity. The limiting member can abut against the water retaining member when the water retaining member closes the second filter inlet.

[0129] In this way, the water blocking member can unidirectionally open the second filter inlet under the support of the limiting member to prevent the washing water entering the filter cavity from flowing back from the second filter inlet.

[0130] In some embodiments of the present application, the limiting member includes a stop surface that cooperates with the water blocking member to limit the position. The stop surface is tilted so that the water blocking member is tilted when the second filter inlet is closed, and the connection end of the water blocking member and the box body is lower than the free end of the water blocking member.

[0131] Thus, the inclined stop surface allows the water retaining member to be inclined when closing the second filter inlet. In this way, the inclined water retaining member is more easily flushed away by the washing water surging and flowing upward from below to open the second filter inlet, thereby improving the filtering efficiency of the washing device.

[0132] In some embodiments of the present application, the pulsator washing machine further includes:

[0133] The washing component is arranged on one side of the box body facing the washing cavity and is located between the first filter outlet and the second filter outlet along the circumference of the inner cylinder.

[0134] In this way, the scrubbing element can contact the textiles in the washing chamber, thereby scraping the hair and hair debris on the textiles into the washing water, so that the hair attached to the textiles is effectively dispersed in the washing water as much as possible and enters the filter device with the washing water, so that as much hair as possible is collected in the filter device.

[0135] In some embodiments of the present application, the box body further includes:

[0136] A plurality of mounting holes are provided on the box body and located between the first filter outlet and the second filter outlet;

[0137] Washing parts include:

[0138] A connecting portion, the connecting portion abuts against the box body and is located in the filter cavity;

[0139] A plurality of scrubbing heads are provided, one end of each scrubbing head is connected to the connecting portion, the other end of each scrubbing head passes through the mounting hole and extends into the washing cavity, and the scrubbing head is snap-fitted with the mounting hole.

[0140] In this way, when the washing component needs to be installed on the box body, the connecting part can be clamped on the second shell, and the washing head can be aligned with the mounting hole and the connecting part can be pressed down. The washing head passes through the mounting hole and is clamped in the mounting hole, so that the washing component can be stably set on the second shell, and the installation efficiency of the washing component is also improved.

[0141] In some embodiments of the present application, there are multiple first filter outlets and arranged along the axial direction of the inner cylinder, there are multiple second filter outlets and arranged along the axial direction of the inner cylinder, and there are multiple scrubbing heads and arranged along the axial direction of the inner cylinder;

[0142] Along the radial direction of the inner cylinder, each scrubbing head is located between a first filter outlet and a second filter outlet.

[0143] In this way, the hair hanging on the scrubbing head can be prevented from being washed away by the washing water flowing out of the first filter outlet and the second filter outlet, so that the user can clean the hair after washing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0189] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0190] In this application, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0191] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0192] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0193] In addition, the terms "first," "second," etc. are primarily used to distinguish different devices, elements, or components, and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0194] A pulsator washing machine consists of an inner drum, an outer tub, and a filter assembly mounted in the inner drum. A circulation channel is defined between the two tubs. Wash water flows through holes in the bottom of the inner drum into the circulation channel and then into the filter assembly, where it filters and collects hair and lint.

[0195] When the filter collects hair, lightweight, non-sinking hair and lint are not easily caught. Furthermore, with socioeconomic development and accelerated urbanization, pet ownership has become a popular pastime for many families. With the increasing demand for pets, cleaning pet products has become a common challenge for the laundry industry. It should be noted that pet hair is long, lightweight, and difficult to separate from textiles, placing even higher demands on the filter's performance.

[0196] Therefore, in conventional pulsator washing machines, rinsing cannot remove hair from textiles. Furthermore, most hair that has escaped from textiles, due to its light weight, floats in the upper layer of the wash water and has difficulty sinking to the bottom of the inner drum, making it difficult for the hair to enter the circulation channel and filter assembly. Furthermore, due to its long length, hair also has difficulty passing through the through-holes at the bottom of the inner drum, resulting in poor hair removal effectiveness in pulsator washing machines.

[0197] In some solutions, a filter device is installed on the wall of the inner drum to remove hair. However, these solutions do not provide ideal cleaning results. Hair floating on the upper layer of the wash water cannot be collected, and hair easily becomes entangled in the filter device, affecting the cleaning effect of the filter device. Moreover, hair collected in the filter device is also prone to flow out of the filter device. In addition, these solutions require significant changes to the structure of the inner drum, which greatly increases production costs.

[0198] This application proposes a pulsator washing machine 100, which is described below with reference to Figure 1-Figure 37 The pulsator washing machine 100 will be described.

[0199] like Figure 1 As shown, the pulsator washing machine 100 includes a housing 20. The housing 20 is used to form the overall appearance of the pulsator washing machine 100. The interior of the housing 20 is hollow to form a receiving chamber 101. The receiving chamber 101 is configured to accommodate various components of the pulsator washing machine 100, such as circuits, drive components, and drainage components. The housing 20 can be a rectangular parallelepiped for placement near a wall. Of course, the housing 20 can also be a cylinder to accommodate circular components within the pulsator washing machine 100.

[0200] The side panels at the top of the housing 20 can be opened to form a clothing loading port. When the side panels at the top of the housing 20 are opened, the user can place laundry (such as clothing) into the pulsator washing machine 100 for washing. The side panels at the top of the housing 20 can also be provided with a door, which is used to close the clothing loading port during washing. It is understood that a glass window can also be provided on the door to facilitate observation of the washing process. Alternatively, the clothing loading port can be located elsewhere in the housing 20.

[0201] The height of the box 20 is from the bottom to the top of the box 20. The box 20 also has a width and a front-to-back direction. The width of the box 20 is from one end of the box 20 to the other end of the box 20. The front of the box 20 is the side of the box 20 facing the user. Any two of the width, front-to-back, and height directions of the box 20 are perpendicular to each other.

[0202] like Figure 2As shown, the pulsator washing machine 100 includes a barrel assembly, which is arranged in the box body 20 and is used to wash clothes. The barrel assembly has a washing cavity 11, and clothes are put into the washing cavity 11 through a clothes loading port opened on the barrel assembly for washing.

[0203] like Figure 4 As shown, the tub assembly may include an outer tub 10 , which is disposed in a box body 20 , and an outer tub cavity is formed in the outer tub 10 .

[0204] like Figure 4 As shown, the barrel assembly may include an inner barrel assembly 12. The inner barrel assembly 12 is disposed within the outer barrel 10.

[0205] In some embodiments, as Figure 4 As shown, the inner drum assembly 12 includes an inner drum 1, which is arranged in the outer drum cavity and can rotate relative to the outer drum 10. A washing chamber 11 is provided in the inner drum 1, and objects to be washed can be placed in the washing chamber 11.

[0206] In some embodiments, as Figure 4 As shown, the inner drum assembly 12 may include a balancing ring 13. The balancing ring 13 is disposed inside the inner drum 1 and connected to the top of the inner drum 1. The balancing ring 13 is used to maintain the stability and balance of the pulsator washing machine 100 during high-speed rotation and reduce severe vibration or noise caused by imbalance of the inner drum 1.

[0207] In some embodiments, as Figure 4 As shown, the inner drum assembly 12 may include an inner drum bottom cover 14. The inner drum bottom cover 14 is connected to the bottom of the inner drum 1, and the inner drum bottom cover 14 is used to close the bottom opening of the inner drum 1 to prevent the inner drum 1 from deforming and to accommodate the pulsator 2.

[0208] In some embodiments, as Figure 4 As shown, the inner cylinder assembly 12 includes a first through hole 111 , which is provided on the cylinder wall of the inner cylinder 1 and the inner cylinder bottom cover 14 .

[0209] In some embodiments, as Figure 4 As shown, a circulation channel 43 for accommodating washing water is provided between the inner peripheral wall of the outer tub 10 and the outer peripheral wall of the inner drum assembly 12 , and the washing chamber 11 is connected to the circulation channel 43 through the first through hole 111 .

[0210] In this way, the washing water in the inner drum assembly 12 can flow into the circulation channel 43 through the upper first through hole 111 of the inner drum bottom cover 14, so that the washing water can be discharged from the pulsator washing machine 100 through the drainage component connected to the outer barrel 10. The washing water in the circulation channel 43 can flow into the washing chamber 11 through the first through hole 111 on the wall of the inner drum 1 to wash the laundry. In some embodiments, a pulsator 2 is provided at the bottom of the inner drum 1, and there is a gap between the pulsator 2 and the bottom of the inner drum 1. The driving device 3 is connected to the pulsator and can drive the pulsator to rotate in a first direction (forward) and a second direction (reverse). The pulsator 2 rotates to stir the washing water in the inner drum 1 and drives the clothes to rotate with the pulsator 2 to wash the clothes. In the process of the pulsator 2 driving the washing water to rotate, centrifugal force is generated, causing the washing water to surge up and down.

[0211] In some embodiments, the pulsator washing machine 100 may include a driving device 3. The driving device 3 is disposed in the outer tub 10 and connected to the pulsator 2. The driving device 3 is configured to drive the pulsator 2 to rotate.

[0212] In some embodiments, as Figure 3 As shown, the pulsator 2 can rotate in a first direction (forward) and a second direction (reverse) to improve the washing effect. In this case, the inner drum 1 does not rotate.

[0213] In some embodiments, as Figure 2 As shown, the pulsator 2 may include a second through-hole 21, which connects the washing chamber 11 and the circulation channel 43. Thus, when the pulsator 2 drives the wash water to rotate, the wash water can flow into the circulation channel 43 through the first through-holes in the inner drum 1 and the inner drum bottom cover 14, and the second through-hole 21 of the pulsator 2. Furthermore, driven by the centrifugal force generated by the pulsator 2, the wash water can flow in the circulation channel 43 in a direction away from the pulsator 2 (e.g., upward).

[0214] In some embodiments, the second through hole of the pulsator 2 may be located at the center of the pulsator 2. Since the negative pressure at the center of the pulsator 2 is the greatest due to the centrifugal force when the pulsator 2 rotates, the second through hole 21 may be located at the center of the pulsator 2 to allow hair floating on the upper layer of the wash water to sink to the bottom of the inner drum 1, thereby improving the hair cleaning and collection effect of the pulsator washing machine 100.

[0215] In some embodiments, as Figure 3 As shown, a filter device 9A is provided on the wall of the inner cylinder, and the filter device 9A is used to filter and contain hair scraps.

[0216] In some embodiments, as Figure 3 and Figure 5As shown, the filter device 9A may include a flow guide bracket 92, which is arranged on the wall of the inner tube. A first flow guide channel 921 is formed in the flow guide bracket 92, and a first flow guide portion 9211 is formed on the side of the first flow guide channel 921 close to the inner tube. A first filter port 922 is provided on the side of the first flow guide channel 921 away from the inner tube.

[0217] In some embodiments, as Figure 5 As shown, the first filter port 922 is provided on a side of the guide bracket 92 away from the inner drum, and water in the washing chamber can enter the first guide channel 921 and flow out through the first filter port 922 .

[0218] In some embodiments, as Figure 5 As shown, the filter device 9A may include a filter screen 911 , which is provided with mesh holes. The size of the mesh holes is not conducive to the passage of hair debris. When the washing water flows through the filter screen 911 , the hair debris can be filtered on the filter screen 911 .

[0219] The pulsator rotates to drive the washing water to flow through the first guide channel 921 to the first filter port 922 , and the filter screen 911 can filter the hair debris on the filter screen 911 .

[0220] In this embodiment, a first guide channel 921 is provided to guide the washing water to the filter 911 to clean and collect hair. Since hair easily floats in the washing water in the washing chamber, under the action of the forward and reverse rotation of the impeller, the washing water drives the hair debris to flow through the filter 911, thereby filtering the hair debris on the filter 911.

[0221] In some embodiments, the filter device 9A is detachably connected to the inner cylinder, which allows the filter device 9A to be easily disassembled and facilitates the user to clean the animal hair filtered and collected in the filter device 9A.

[0222] The present application provides the filtering device 9A without making any changes to the inner cylinder, thereby reducing the modification cost and improving the versatility of the structure.

[0223] In some embodiments, as Figure 5 As shown, by providing the filter 911, animal hair and hair debris can be filtered on the filter 911, thereby reducing the collected hair from flowing back into the washing chamber.

[0224] In some embodiments, as Figure 2 and Figure 3 As shown, a second guide portion 9212 may be formed on one side of the first guide channel 921 close to the inner tube, and the first guide portion 9211 and the second guide portion 9212 are respectively connected to two opposite sides of the guide bracket 92 .

[0225] The first guide portion 9211 is smoothly extended in a direction close to the first filter port 922 , and the second guide portion 9212 is smoothly extended in a direction close to the first filter port 922 .

[0226] In some embodiments, as Figure 3 As shown, the first guide portion 9211 and the second guide portion 9212 are symmetrically arranged.

[0227] When the pulsator rotates, the washing water flows to the first filter port 922 through the first guide portion 9211 or the second guide portion 9212 , and the filter screen 911 filters the hair debris on the filter screen 911 .

[0228] In this embodiment, a first guide channel 921 is provided to guide the washing water to the filter 911 to clean and collect hair. A first guide portion 9211 and a second guide portion 9212 are provided to smoothly transition to the first filter port 922 to guide the washing water to the filter 911, thereby filtering the hair debris on the filter 911.

[0229] like Figure 3 As shown, the first guide part 9211 and the second guide part 9212 are respectively connected to the opposite sides of the guide bracket 92, so that when the impeller rotates forward and reverse, the washing water can flow through the first guide part 9211 or the second guide part 9212 to the filter 911, filtering the hair debris on the filter 911, thereby improving the effect of collecting hair.

[0230] In some embodiments, as Figure 5 As shown, the filter device 9A may include a second shell 93 , and the second shell 93 is arranged corresponding to the first filter port 922 .

[0231] In some embodiments, as Figure 5 and Figure 6 As shown, a filter cavity outlet 931 is provided on the second shell 93 , and the washing water can flow through the filter screen 911 and the filter cavity outlet 931 under the guidance of the first guide part 9211 or the second guide part 9212 .

[0232] The second shell 93 can limit the filter 911 .

[0233] In some embodiments, as Figure 5 As shown, the filter device 9A may include a first filter pressure plate 94, which may be in contact with the filter screen 911. The filter screen 911 is arranged between the second shell 93 and the first filter pressure plate 94. The filter screen 911 can be pressed tightly by the restriction of the second shell 93 and the first filter pressure plate 94 to prevent the filter screen 911 from moving, thereby improving the filtering effect.

[0234] In some embodiments, as Figure 5As shown, the filter device 9A includes a first shell 95 , which is disposed between the second shell 93 and the filter screen 911 .

[0235] In some embodiments, the first housing 95 may abut against the first filter platen 94 to prevent the first filter platen 94 from moving.

[0236] In some embodiments, as Figure 5 As shown, the first housing 95 may be provided with a first filter inlet 951, and the first filter inlet 951 is provided corresponding to the first filter port 922. Wash water may flow to the first filter inlet 951 and the first filter port 922 through the first guide channel 921.

[0237] In some embodiments, the opening area of ​​the first filter port 922 is larger than the opening area of ​​the first filter inlet 951, that is, the opening area of ​​the first filter inlet 951 is smaller than the opening area of ​​the first filter port 922. When the wash water flows through the first filter inlet 951, the water flow rate can be increased to prevent animal hair from forming a blockage at the first filter inlet 951.

[0238] In some embodiments, the first shell 95 is connected to the second shell 93 to fix the filter 911 .

[0239] In some embodiments, as Figure 5 As shown, the first shell 95 and the second shell 93 are connected by a snap-fitting manner, so that the user can disassemble the first shell 95 and the second shell 93 to clean the animal hair attached to the filter 911.

[0240] In some embodiments, the first shell 95 and the second shell 93 are connected by a hinge at one end, so that the user can disassemble the first shell 95 and the second shell 93 by rotating the second shell 93, thereby facilitating the cleaning of animal hair attached to the filter 911.

[0241] In some embodiments, the second housing 93 is detachably connected to the air guide bracket 92 , so that the user can remove the second housing 93 and then clean the hair debris on the filter 911 .

[0242] In some embodiments, as Figure 5 As shown, the filtering device 9A may include a first water inlet 936 and a second water inlet 937. The first water inlet 936 and the second water inlet 937 are arranged on the guide bracket 92 and on opposite sides of the impeller in the rotation direction.

[0243] In some embodiments, as Figure 2 、 Figure 3 and Figure 5As shown, the first water inlet 936 is connected to the first guide part 9211. When the pulsator rotates forward for washing, the washing water enters the first guide channel 921 through the first water inlet 936, and flows to the filter 911 through the first guide part 9211. The filter 911 can filter the hair in the washing water.

[0244] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 As shown, the second water inlet 937 is connected to the second guide part 9212. When the pulsator rotates in the reverse direction for washing, the washing water enters the second guide channel 927 through the second water inlet 937 and flows to the filter 911 through the second guide part 9212. The filter 911 can filter the hair in the washing water.

[0245] In some embodiments, as Figure 5 As shown, a second mounting portion 932 is provided on the top of the second shell 93, and the air guide bracket 92 is provided with a second assembly portion 923 that cooperates with the second mounting portion 932. The second mounting portion 932 is inserted into the second assembly portion 923 to connect the top of the second shell 93 with the air guide bracket 92.

[0246] In some embodiments, as Figure 5 As shown, a third mounting portion 933 is provided at the bottom of the second shell 93, and the air guide bracket 92 is provided with a third assembly portion 924 that cooperates with the third mounting portion 933. The third mounting portion 933 is inserted into the third assembly portion 924 to connect the bottom of the second shell 93 with the air guide bracket 92.

[0247] The snap-fit ​​connection method can facilitate the second shell 93 and the air guide bracket 92 to be disconnected under the action of external force to disassemble the second shell 93.

[0248] In some embodiments, the second mounting portion 932 is detachably connected to the second assembly portion 923. The user presses the second mounting portion 932 to cause the second mounting portion 932 to elastically deform, thereby snapping the second mounting portion 932 into the second assembly portion 923. After the user stops pressing the second mounting portion 932, the shape of the second mounting portion 932 is restored and can be pressed tightly against the second assembly portion 923, thereby realizing the detachable connection between the second mounting portion 932 and the second assembly portion 923.

[0249] When the user needs to disassemble the filter device 9A, the user presses the second mounting portion 932 to disconnect the second mounting portion 932 from the second assembly portion 923, thereby disassembling the second shell 93 and the guide bracket 92, and cleaning the hair by disassembling the second shell 93.

[0250] In some embodiments, the diversion bracket 92 can be connected to the inner cylinder through fasteners to improve the connection effect of the diversion bracket 92. Figure 2 、 Figure 3 As shown, the flow guide bracket 92 includes a bracket body 920. The flow guide bracket 92 also includes a first filter port 922, which is located on a side of the bracket body 920 away from the inner drum 1. A first end of a first flow guide channel 921 communicates with the washing chamber 11, and a second end communicates with the first filter port 922. Thus, wash water within the washing chamber 11 can enter the first flow guide channel 921 and flow out through the first filter port 922.

[0251] In some embodiments, as Figure 3 As shown, the flow guide bracket 92 further includes a first flow guide portion 9211. The first flow guide portion 9211 is configured to guide wash water flowing into the first flow guide channel 921 to the first filter port 922. The first flow guide portion 9211 comprises at least a portion of the wall of the bracket body 920 near the inner drum 1. The first flow guide portion 9211 is arc-shaped and extends toward the first filter port 922. For example, the first end of the first flow guide portion 9211 is connected to an end of the first side of the bracket body 920 near the inner drum 1, and the second end extends away from the inner drum 1 and toward the first filter port 922.

[0252] In this way, when the pulsator 2 rotates, the extension direction of the first guide portion 9211 can match the flow direction (e.g., the first direction) of the wash water in the washing chamber 11 on the horizontal plane, thereby reducing the resistance of the wash water flowing in the first guide channel 921 and avoiding affecting the flow rate of the wash water, thereby improving the cleaning effect of the pulsator washing machine 100. In addition, by arranging the first end (e.g., the water inlet end) of the first guide portion 9211 close to the inner wall of the inner drum 1, it is possible to facilitate the flow of wash water close to the inner wall of the inner drum 1 into the first guide channel 921, thereby avoiding the wash water close to the inner wall of the inner drum 1 from having difficulty in quickly flowing into the first guide channel 921 due to the excessive distance between the first end of the first guide portion 9211 and the inner wall of the inner drum 1.

[0253] Furthermore, by providing the first guide portion 9211 with an arc shape, the flow resistance of the wash water in the first guide channel 921 can be further reduced, thereby facilitating the circulation of the wash water in the washing chamber 11. The first guide portion 9211 is integrally formed with the bracket body 920, which can also improve the structural strength of the first guide portion 9211 and prevent deformation of the first guide portion 9211 due to the impact of the water flow.

[0254] It should be noted that the first side of the bracket body 920 is one of the two sides of the bracket body 920 in the circumferential direction of the inner tube 1 .

[0255] In some embodiments, as Figure 2As shown, the angle between the tangent line at the second end of the first air guide portion 9211 and the tangent line at the corresponding point of the inner cylinder 1 is less than a predetermined angle. Here, the tangent line at the second end of the first air guide portion 9211 can be understood as the tangent line at the end point of the curve formed by the first and second ends of the first air guide portion 9211. The tangent line at the corresponding point of the inner cylinder 1 can be understood as a straight line perpendicular to the radial direction of the inner cylinder 1 passing through that point on the first air guide portion 9211.

[0256] In this way, the angle between the flow direction of the washing water flowing out of the first guide channel 921 and the flow direction of the washing water flowing along the first direction in the washing chamber 11 is small, which avoids obstruction of the flow of the washing water in the washing chamber 11 when the washing water flowing out of the first guide channel 921 merges into the washing water flowing in the washing chamber 11, thereby improving the cleaning effect of the pulsator washing machine 100.

[0257] It can be understood that, the larger the preset angle, the greater the difference between the flow direction of the washing water flowing out of the first guide channel 921 and the flow direction of the washing water in the washing chamber 11, and the washing water flowing out of the first guide channel 921 is likely to collide with the washing water flowing in the washing chamber 11, affecting the circulation flow of the washing water in the washing chamber 11.

[0258] In some embodiments, as Figure 3 As shown, the extension trajectory of the first guide portion 9211 can be substantially tangent to the wall of the inner drum 1 to reduce the resistance of the wash water in the washing chamber 11 when flowing into the first guide channel 921. Here, the extension trajectory of the first guide portion 9211 can be understood as a curve formed by the first end of the first guide portion 9211 extending to the second end of the first guide portion 9211.

[0259] In some embodiments, the first end of the first flow guide 9211 is rotatably connected to the first side of the bracket body 920. In this way, the distance between the first flow guide 9211 and the inner wall of the inner cylinder 1 can be adjusted to accommodate inner cylinders 1 of different sizes, thereby improving the versatility of the filter device 9A.

[0260] In some embodiments, as Figure 3 As shown, the second guide portion 9212 is configured to guide wash water flowing into the second guide channel 927 to the first filter port 922. The second guide portion 9212 comprises at least a portion of the wall of the support body 920 near the inner drum 1. The second guide portion 9212 is arc-shaped and extends toward the first filter port 922. For example, the first end of the second guide portion 9212 is connected to the end of the second side of the support body 920 near the inner drum 1, and the second end extends away from the inner drum 1 and toward the first filter port 922.

[0261] The structure and function of the second guide portion 9212 are similar to those of the first guide portion 9211 and will not be described in detail herein.

[0262] In some embodiments, as Figure 2 As shown, the second guide portion 9212 and the first guide portion 9211 are respectively connected to two sides of the bracket body 920 in the circumferential direction of the inner cylinder 1 and are symmetrically arranged relative to the radial direction of the inner cylinder 1.

[0263] When the pulsator 2 rotates forward or reverse, the washing water in the washing chamber 11 can flow to the first filter port 922 through the first guide portion 9211 or the second guide portion 9212. In this way, regardless of whether the pulsator 2 rotates forward or reverse, the filter device 9A can clean and collect hair, thereby improving the effect of cleaning and collecting hair.

[0264] In some embodiments, the flow guide bracket 92 may include multiple first flow guide channels 921. For example, the flow guide bracket 92 may include multiple first flow guide portions 9211 or second flow guide portions 9212. These multiple first flow guide portions 9211 or second flow guide portions 9212 are arranged sequentially away from the inner drum 1 to form multiple first flow guide channels 921. This allows the wash water flowing into the filter device 9A to be diverted, increasing the flow rate of the wash water within the first flow guide channels 921 and preventing hair from clogging the first flow guide channels 921.

[0265] In some embodiments, as Figure 5 As shown, the filter device 9A further includes a filter screen 911. The filter screen 911 is disposed within the first flow guide channel 921 and is configured to filter the wash water, thereby filtering out hair in the wash water. The filter screen 911 has mesh holes, and the aperture of the mesh holes can be smaller than a preset value to block hair. Thus, when the pulsator 2 rotates to drive the wash water through the first flow guide channel 921 to the first filter port 922, the wash water can flow through the filter screen 911, and the hair in the wash water can be filtered at the filter screen 911, thereby preventing the collected hair from flowing back into the washing chamber 11.

[0266] In some embodiments, by providing the first guide channel 921, the washing water in the washing chamber 11 can be easily guided to the filter 911, thereby improving the effect of the filter device 9A in cleaning and collecting hair.

[0267] In some embodiments, as Figure 5 As shown, the filter device 9A further includes a second housing 93. The second housing 93 is connected to the flow guide bracket 92 and is disposed at the first filter port 922. The second housing 93 is configured to limit the filter screen 911.

[0268] In some embodiments, as Figure 5 and Figure 6 As shown, the second housing 93 includes a fourth body 930. The second housing 93 also includes a filter chamber outlet 931. The filter chamber outlet 931 passes through the fourth body 930 and connects the first filter port 922 and the washing chamber 11. Wash water flows through the filter screen 911 and the filter chamber outlet 931 under the guidance of the first guide 9211 or the second guide 9212.

[0269] In some embodiments, the second shell 93 can be detachably connected to the diversion bracket 92 to facilitate the user to remove the second shell 93 to centrally clean the hair on the filter 911 .

[0270] In some examples, such as Figure 5 and Figure 6 As shown, the second housing 93 further includes a second mounting portion 932. The second mounting portion 932 is disposed on a side of the fourth body 930 away from the impeller 2 (eg, the top).

[0271] The second housing 93 further includes a third mounting portion 933. The third mounting portion 933 is disposed on a side of the fourth body 930 close to the impeller 2 (eg, the bottom).

[0272] Correspondingly, if Figure 5 As shown, the air guide bracket 92 further includes a second assembly portion 923. The second assembly portion 923 is connected to the second mounting portion 932. For example, the second mounting portion 932 is inserted into the second assembly portion 923 to connect the top of the fourth body 930 to the air guide bracket 92.

[0273] like Figure 5 As shown, the air guide bracket 92 also includes a third assembly portion 924. The third assembly portion 924 is connected to the third mounting portion 933. In some examples, the third mounting portion 933 is inserted into the third assembly portion 924 to connect the bottom of the fourth body 930 to the air guide bracket 92. For example, the third assembly portion 924 includes a third groove, which is located at one end (such as the bottom) of the bracket body 920 close to the impeller 2, and the notch faces the second shell 93. The third mounting portion 933 includes a protrusion, which is located at the bottom of the fourth body 930 and protrudes from the fourth body 930. The protrusion can be inserted into the third groove to achieve the plug-in connection between the third mounting portion 933 and the third assembly portion 924.

[0274] In this way, the second shell 93 and the air guide bracket 92 can be easily disconnected under the action of external force through the snap-fit ​​connection, thereby facilitating the disassembly of the second shell 93.

[0275] In some embodiments, the second mounting portion 932 is detachably connected to the second assembly portion 923 .

[0276] For example, Figure 7As shown, the second assembly portion 923 includes two first grooves. The second assembly portion 923 also includes a second groove. The first groove is provided at an end (e.g., the top) of the bracket body 920 away from the impeller 2, with the notch facing the second housing 93. The second groove is located between the two first grooves, and the side of the second groove away from the inner cylinder 1 is open.

[0277] Correspondingly, if Figure 7 As shown, the second mounting portion 932 includes a main body 9320. The first end of the main body 9320 is connected to the top of the fourth body 930, and the second end extends first away from the fourth body 930 and then away from the inner cylinder 1. The second end of the main body 9320 is spaced apart from the fourth body 930. A portion of the second end of the main body 9320 is located in the second groove.

[0278] The second mounting portion 932 also includes two stoppers 9321 (e.g., protrusions). These two stoppers 9321 are located at the second end of the main body 9320 and protrude away from the fourth body 930. The length of these stoppers 9321 is approximately perpendicular to the circumference of the inner drum 1. These two stoppers 9321 can be inserted into the two first grooves to limit the position of the second housing 93 in the circumferential direction of the inner drum 1. This prevents the second housing 93 from being displaced by the impact of wash water.

[0279] Thus, when the second mounting portion 932 is pressed, it elastically deforms, allowing it to engage with the second assembly portion 923. After the second mounting portion 932 and the second assembly portion 923 are engaged, the external force acting on the second mounting portion 932 is removed and the shape is restored, allowing the second mounting portion 932 to be tightly pressed against the second assembly portion 923. In this way, a detachable connection between the second mounting portion 932 and the second assembly portion 923 is achieved.

[0280] The second groove facilitates pressing the second mounting portion 932. Therefore, when the second housing 93 needs to be disassembled, the second mounting portion 932 can be disengaged from the second assembly portion 923 by pressing the second mounting portion 932 (e.g., the portion of the second end of the main body 9320 located in the second groove), thereby removing the second housing 93 from the air guide bracket 92 for hair removal.

[0281] In some embodiments, as Figure 5 and Figure 8A As shown, the filter device 9A further includes a first filter platen 94. The first filter platen 94 abuts against the filter screen 911, and the filter screen 911 is disposed between the second housing 93 and the first filter platen 94. The second housing 93 and the first filter platen 94 compress the filter screen 911, preventing it from moving and thereby improving the filtering effect of the filter screen 911.

[0282] In some embodiments, the first filter plate 94 is detachably connected to the filter screen 911. Figure 8B and Figure 8C As shown, the first filter platen 94 includes a plate body 943. The first filter platen 94 also includes a mounting portion 942 (e.g., a slot). The mounting portion 942 is disposed within the plate body 943, and one end (e.g., the bottom) of the mounting portion 942 is open to facilitate insertion of the filter screen 911 into the first filter platen 94.

[0283] The side of the first housing 95 near the first guide portion 9211 or the second guide portion 9212 can guide wash water flowing into the first guide channel 921 or the second guide channel 927 to the first filter inlet 951, further reducing the flow resistance of the wash water in the first guide channel 921 and the second guide channel 927. Furthermore, the provision of the first housing 95 can also reduce the cross-sectional dimensions of the first guide channel 921 and the second guide channel 927 along the flow direction of the wash water, thereby increasing the flow rate of the wash water in the first guide channel 921 and preventing hair from clogging the first guide channel 921.

[0284] In some embodiments, the opening area of ​​the first filter port 922 is larger than the opening area of ​​the first filter inlet 951. Thus, when the wash water flows through the first filter inlet 951, the flow rate of the wash water can be increased, thereby preventing animal hair from clogging the first filter inlet 951.

[0285] For example, Figure 5 As shown, connecting shafts 9412 are provided on both sides of the first end of the first shell 95. First mounting portions 953 (such as snaps) are provided on both sides of the second end of the first shell 95. Correspondingly, the second shell 93 also includes connecting holes 9411, which are located on both sides of the bottom end of the fourth body 930, and the connecting shafts 9412 are inserted into the connecting holes 9411 to rotatably connect the first end of the first shell 95 to the second shell 93. The second shell 93 also includes a first assembly portion 939 (such as a card slot), which is located on both sides of the top end of the fourth body 930, and the first mounting portion 953 is snap-fitted to the first assembly portion 939 to connect the second end of the first shell 95 to the second shell 93.

[0286] It should be noted that, since the rotation direction of the first shell 95 when hinged is perpendicular to the flow direction of the washing water (such as clockwise or counterclockwise), the first shell 95 can be prevented from being separated from the second shell 93 by the impact of the washing water.

[0287] In some embodiments, as Figure 10As shown, the filter device 9A further includes a plurality of water guide holes 9361. At least some of the water guide holes 9361 are disposed on both sides of the guide bracket 92 in the circumferential direction of the inner drum 1. The plurality of water guide holes 9361 connect the washing chamber 11 and the first guide channel 921.

[0288] For example, Figure 10 As shown, the filter device 9A further includes a plurality of first support ribs 9207 and a plurality of second support ribs 9208. These ribs are disposed on either side of the flow guide bracket 92 circumferentially of the inner drum 1. These ribs are spaced apart along the height of the pulsator washing machine 100 to form a plurality of water guide holes 9361. The first and second water inlets 936, 937 are separated into a plurality of water guide holes 9361 by these ribs. Each first support rib 9207 can extend circumferentially along the inner drum 1, and its size decreases as it moves away from the flow guide bracket 92, thereby reducing resistance to wash water flowing into the first flow guide channel 921. Furthermore, these ribs can enhance the structural strength of the flow guide bracket 92.

[0289] The first water guide hole 9361 is located on the first side of the bracket body 920 connected to the first guide part 9211. When the pulsator 2 rotates forward, the washing water enters the first guide channel 921 through the first water guide hole 9361 and flows to the filter 911 through the first guide part 9211.

[0290] The second water guide hole 9361 is located on the second side of the bracket body 920 connected to the second guide part 9212. When the pulsator 2 rotates in the opposite direction, the washing water enters the second guide channel 927 through the second water guide hole 9361 and flows to the filter 911 through the second guide part 9212.

[0291] It should be noted that the radial size of the multiple first support ribs 9207 in the inner drum 1 is smaller than or equal to the radial size of the guide bracket 92 in the inner drum 1, thereby preventing the first support ribs 9207 from protruding from the second shell 93 and affecting the flow of washing water in the washing chamber 11.

[0292] In some embodiments, as Figure 11 、 Figure 12A 、 Figure 12B As shown, a scrubbing member 96 may be provided on the second shell 93 , and the scrubbing member 96 is provided on a side of the second shell 93 close to the washing chamber.

[0293] When the pulsator rotates, the scrubbing member 96 contacts the laundry, and when in contact with the laundry, the scrubbing member 96 can scrape hair off the laundry into the washing water, thereby effectively separating the hair from the laundry, making it easier for the filter device 9A to collect the hair.

[0294] In some embodiments, as Figure 13 As shown, the second shell 93 includes at least one mounting hole 934 , and a washing component 96 is correspondingly connected to the mounting hole 934 .

[0295] The washing component may be connected to the mounting hole 934 by at least one of plugging, pasting or integral molding.

[0296] In some embodiments, as Figure 12A and Figure 13 As shown, the second shell 93 includes a reinforcement portion 935, which is arranged corresponding to the mounting hole 934, and the washing part is passed through the reinforcement portion 935. The reinforcement portion 935 can play a role in limiting the washing part, increasing the contact area between the washing part and the reinforcement portion 935, and improving the connection effect between the washing part and the second shell 93.

[0297] In some embodiments, the scrubbing member 96 may be made of a flexible material.

[0298] In some embodiments, the scrubbing member 96 may be configured as a scraper, with multiple scrapers disposed in the same mounting hole 934 , with some of the scrapers being located in the washing cavity.

[0299] In some embodiments, the shaving bristles are configured as cylindrical shaving bristles.

[0300] In some embodiments, as Figure 13 As shown, the second housing 93 further includes a mounting hole 934. The mounting hole 934 is provided on a side of the fourth body 930 close to the washing chamber 11 and passes through the fourth body 930. The scrubbing member 96 is connected in the mounting hole 934.

[0301] The cleaning member 96 can be plugged into the mounting hole 934 to facilitate the removal of the cleaning member 96; or, the cleaning member 96 can be pasted to the mounting hole 934 to improve the fixation of the cleaning member 96 and the second shell 93; or, the cleaning member 96 can be integrally formed with the mounting hole 934 to reduce costs.

[0302] It should be noted that a plurality of scraping bristles can be provided in a mounting hole 934 to improve the cleaning effect of the scrubbing member 96 .

[0303] In some embodiments, the second shell 93 may include a plurality of mounting holes 934 , and the plurality of mounting holes 934 are spaced apart along the height direction of the pulsator washing machine 100 to increase the cleanable area of ​​the scrubbing member 96 .

[0304] In some embodiments, as Figure 13 As shown, the second housing 93 further includes a reinforcement portion 935 (flange). The reinforcement portion 935 is provided corresponding to the scraper mounting hole 934. The brush member 96 can be provided through the reinforcement portion 935. The reinforcement portion 935 is configured to limit the position of the brush member 96. The reinforcement portion 935 can increase the contact area between the brush member 96 and the reinforcement portion 935, thereby improving the connection between the brush member 96 and the second housing 93.

[0305] In some embodiments, filter device 9A is detachably connected to inner barrel 1. This facilitates installation and removal of filter device 9A, thereby facilitating cleaning of the hair filtered and collected within filter device 9A. Furthermore, the provision of a detachable filter device 9A reduces modifications to inner barrel 1, thereby reducing modification costs and improving the structural versatility of inner barrel 1.

[0306] In some examples, such as Figure 14 As shown, the deflector bracket 92 also includes a hanger 925 (e.g., a hook). The hanger 925 is disposed on a side of the bracket body 920 near the inner tube 1. Correspondingly, the inner tube 1 has a fourth positioning portion (e.g., a latch hole). The hanger 925 is connected to the fourth positioning portion. For example, the hanger 925 is inserted into the fourth positioning portion to connect the deflector bracket 92 to the inner tube 1. The connection between the hanger 925 and the fourth positioning portion allows the installation position of the deflector bracket 92 to be pre-positioned, improving installation efficiency and facilitating fastener connection between the deflector bracket 92 and the inner tube 1.

[0307] Of course, in some embodiments, the flow guide bracket 92 may also be connected to the inner tube 1 via fasteners (such as bolts) to improve the connection effect of the flow guide bracket 92.

[0308] In some embodiments, as Figure 15 As shown, the filter device 9B may include a seventh accommodating chamber 811, which is arranged between the filter device 9B and the inner drum 1, and is respectively connected to the washing chamber and the circulation channel.

[0309] In the washing state, at least part of the washing water flows from the washing chamber through the first guide channel 921, and at least part of the washing water flows from the washing chamber through the circulation channel to the seventh accommodating chamber 811 to filter the hair debris. The hair debris in the washing chamber and the circulation channel can be collected, thereby improving the effect of cleaning hair debris.

[0310] In some embodiments, as Figure 16As shown, the filtering device 9B may include a flow guide bracket 92, which is arranged on the wall of the inner tube 1. A first flow guide channel 921 and a second flow guide channel 927 are formed in the flow guide bracket 92. A first flow guide portion 9211 is formed on the side of the first flow guide channel 921 close to the inner tube 1, and a first filter port 922 is provided on the side of the first flow guide portion 9211 away from the inner tube 1.

[0311] In some embodiments, as Figure 16 As shown, the first filter port 922 is provided on the side of the guide bracket 92 away from the inner drum 1 , and water in the washing chamber can enter the first guide channel 921 and flow out through the first filter port 922 .

[0312] In this embodiment, a first guide channel 921 is provided to guide the washing water to the filter 911 to clean and collect hair. Since hair easily floats in the washing water in the washing chamber, under the action of the forward and reverse rotation of the impeller, the washing water drives the hair debris in the filter to flow through the filter 911, thereby filtering the hair debris on the filter 911.

[0313] In some embodiments, a second guide portion 9212 may be formed on a side of the second guide channel 927 close to the inner tube 1 , and the first guide portion 9211 and the second guide portion 9212 are respectively connected to two opposite sides of the guide bracket 92 .

[0314] The first guide portion 9211 is smoothly extended in a direction close to the first filter port 922 , and the second guide portion 9212 is smoothly extended in a direction close to the first filter port 922 .

[0315] In some embodiments, the first guide portion 9211 and the second guide portion 9212 are symmetrically arranged.

[0316] When the pulsator rotates, the washing water flows to the first filter port 922 through the first guide portion 9211 or the second guide portion 9212 , and the filter screen 911 filters the hair debris on the filter screen 911 .

[0317] In this embodiment, a first guide channel 921 and a second guide channel 927 are provided to guide the washing water to the filter 911 to clean and collect hair. The first guide part 9211 and the second guide part 9212 are provided to smoothly transition to the first filter port 922 to guide the washing water to the filter 911, thereby filtering the hair debris on the filter 911.

[0318] The first guide part 9211 and the second guide part 9212 are respectively connected to the opposite sides of the guide bracket 92, so that when the impeller rotates forward and reverse, the washing water can flow through the first guide part 9211 or the second guide part 9212 to the filter 911, filtering the hair debris on the filter 911, thereby improving the effect of collecting hair.

[0319] In some embodiments, as Figure 17 As shown, the filter device 9B further includes a first filter platen 94. The first filter platen 94 abuts against the filter screen 911, and the filter screen 911 is disposed between the second housing 93 and the first filter platen 94. The second housing 93 and the first filter platen 94 compress the filter screen 911, preventing it from moving and thereby improving the filtering effect of the filter screen 911.

[0320] In some embodiments, as Figure 17 As shown, the second housing 93 further includes a filter cavity outlet 931. The filter cavity outlet 931 penetrates the second housing 93 and communicates with the first filter inlet 951. Wash water flows through the filter screen 911 and the filter cavity outlet 931 under the guidance of the first guide portion 9211 or the second guide portion 9212.

[0321] The pulsator rotates to drive the washing water to flow through the first guide channel 921 to the first filter inlet 951 , and the filter screen 911 can filter the hair debris on the filter screen 911 .

[0322] In this embodiment, a first guide channel 921 is provided to guide the washing water to the filter 911 to clean and collect hair. Since hair easily floats in the washing water in the washing chamber, under the action of the forward and reverse rotation of the impeller, the washing water drives the hair debris in the filter to flow through the filter 911, thereby filtering the hair debris on the filter 911.

[0323] In some embodiments, as Figure 18 and Figure 19 As shown, a filter device 9 is provided on the wall of the inner cylinder 1, and the filter device 9 is used to filter and contain hair and hair scraps.

[0324] like Figure 19 and Figure 20 As shown, the filter device 9 is located in the washing chamber 11 to filter the washing water and contain dander and hair.

[0325] In some embodiments, the filter device 9 can be detachably arranged on the wall of the inner tube 1. In this way, the filter device 9 can be easily removed from the inner tube 1, making it convenient for the user to clean the hair filtered and collected in the filter device 9.

[0326] In some embodiments, as Figure 21 As shown, the filter device 9 may include a flow guide bracket 92. The flow guide bracket 92 is a main component of the filter device 9. The flow guide bracket 92 can be used for installation, support and diversion.

[0327] In some embodiments, as Figure 21As shown, the flow guide bracket 92 may be provided with a hanger 925. A through hole may be formed in the wall of the inner cylinder 1, and the hanger 925 detachably engages with the through hole to removably mount the filter device 9 on the inner cylinder 1. In the event of aging or damage to the filter device 9, the removable mounting arrangement of the filter device 9 and the inner cylinder 1 facilitates replacement of the filter device 9.

[0328] In some embodiments, as Figure 21 As shown, the flow guide bracket 92 can be provided with a fastener 926. The flow guide bracket 92 can be fixedly mounted to the wall of the inner tube 1 by the fastener 926, thereby improving the installation strength of the filter device 9.

[0329] It can be understood that the filter device 9 provided in the embodiment of the present application does not require any changes to the structure of the inner tube 1. It only needs to install the filter device 9 on the inner tube 1, which can reduce the cost of modifying the inner tube 1 and improve the versatility of the filter device 9.

[0330] In some embodiments, as Figure 22 As shown, the flow guide bracket 92 may include a bracket body 920. The bracket body 920 is connected to the wall of the inner tube 1 and is the main structure of the flow guide bracket 92.

[0331] In some embodiments, as Figure 23 and 24 As shown, the flow guide bracket 92 may include a first water inlet 936 . Washing water in the washing chamber 11 may enter the filter device 9 through the first water inlet 936 .

[0332] In some embodiments, the first water inlet 936 can be connected to the washing chamber 11 along the circumference of the inner drum 1, that is, the first water inlet 936 is located on the side of the filter device 9. Due to the rotation of the impeller 2, the wash water can flow along the circumference of the inner drum 1. As the wash water flows along the circumference of the inner drum 1, it can maintain its original flow direction and enter the flow guide bracket 92, thereby increasing the flow rate of the wash water entering the filter device 9.

[0333] Furthermore, wash water flowing along the circumference of the inner drum 1 can enter the filter device 9 through the first water inlet 936, that is, the wash water can enter the filter device 9 through the side of the filter device 9. This eliminates the need for hair to sink to the bottom of the washing chamber 11; as long as the wash water flows along the wall of the inner drum 1, it can enter the filter device 9 through the first water inlet 936, thereby improving the filter device 9's filtering effect on lightweight, non-sinking hair and lint.

[0334] In some embodiments, such as Figure 25As shown, the filter device 9 may include a filter box 97. The filter box 97 is provided on the bracket body 920. The filter box 97 can filter the washing water entering the filter device 9 and collect hair and lint in the filter box 97, thereby achieving the purpose of purifying the washing water.

[0335] In some embodiments, the filter box 97 can be detachably mounted on the support body 920. Since the hair debris is collected in the filter box 97, when the hair debris collected in the filter box 97 needs to be cleaned, the filter box 97 can be removed from the support body 920 without removing the support body 920 from the inner tube 1.

[0336] In some embodiments, the filter box 97 may include a box body 970. The box body 970 is the main structure of the filter box 97. The interior of the box body 970 is hollow to form a filter cavity 971 for filtering wash water.

[0337] In some embodiments, the filter box 97 may include a first filter inlet 951 . The first filter inlet 951 is connected to the filter cavity 971 , so that wash water can enter the filter cavity 971 from the first filter inlet 951 .

[0338] In some embodiments, as Figure 26 As shown, the first filter inlet 951 is provided on the surface of the box body 970 facing the flow guide bracket 92 .

[0339] In some embodiments, as Figure 25 As shown, the filter box 97 includes a filter cavity outlet 931. The filter cavity outlet 931 can be set on the side wall of the box body 970 toward the center of the inner drum 1, and the filter cavity outlet 931 is used for the filtered washing water to flow out of the filter cavity 971 and into the washing cavity 11.

[0340] In some embodiments, as Figure 26 As shown, the filter box 97 may include a filter screen 911. The filter screen 911 is formed with grid holes, the size of which is not conducive to the passage of hair debris. When the washing water flows through the filter screen 911, the hair debris is attached to the filter screen 911, thereby filtering the washing water.

[0341] In some embodiments, the filter 911 can be set at the filter chamber outlet 931, so that when the washing water flows out of the filter chamber outlet 931, the hair and hair debris can be retained in the filter 911, purifying the washing water while preventing the collected hair from flowing back into the washing chamber 11 again.

[0342] In some embodiments, as Figure 25 As shown, there may be multiple filter cavity outlets 931 to improve the filtering efficiency of the filter device 9 .

[0343] In some embodiments, as Figure 23 、 Figure 24 As shown, the air guide bracket 92 may include a first air guide portion 9211. The first air guide portion 9211 is connected to the bracket body 920.

[0344] The first guide portion 9211 is used to guide the washing water flowing into the filter device 9 from the first water inlet 936. The washing water entering from the first water inlet 936 can flow along the first guide portion 9211 and then enter the filter box 97 from the first filter inlet 951 to filter hair debris.

[0345] In some embodiments, as Figure 29 As shown, the first guide portion 9211 may include a first guide surface 9211a. The first guide surface 9211a is away from the wall of the inner drum 1. The first guide surface 9211a is the surface of the first guide portion 9211 that contacts and guides the wash water.

[0346] In some embodiments, as Figure 29 As shown, the first guide surface 9211a includes a second guide section 9211c. Along the circumference of the inner tube 1, the second guide section 9211c is located between the first water inlet 936 and the first filter inlet 951.

[0347] The second flow guiding section 9211c includes two ends away from each other along the circumferential direction of the inner tube 1, namely a first end 9211c1 and a second end 9211c2.

[0348] In some embodiments, the first end 9211c1 of the second guide section 9211c is closer to the first water inlet 936 than the second end 9211c2 , so that the first end 9211c1 of the second guide section 9211c contacts the wash water flowing in from the first water inlet 936 first.

[0349] When the impeller 2 rotates along the first direction, the washing water will flow along the second guide section 9211c. The second end 9211c2 of the first guide portion 9211 is closer to the first filter inlet 951 than the first end 9211c1. The washing water flowing in from the first water inlet 936 will flow along the second guide section 9211c and enter the first filter inlet 951.

[0350] In some embodiments, the first end 9211c1 of the second guide section 9211c is closer to the wall of the inner tube 1 than the second end 9211c2. Meanwhile, the second end 9211c2 of the second guide section 9211c is closer to the center of the inner tube 1 than the first end 9211c1.

[0351] In order to facilitate the passage of washing water flowing along the wall of the inner drum 1, the first water inlet 936 is arranged close to the wall of the inner drum 1, and the first filter inlet 951 is closer to the center of the inner drum 1 than the first water inlet 936. Therefore, the second end 9211c2 of the second guide section 9211c is closer to the center of the inner drum 1 than the first end 9211c1. Therefore, the second guide section 9211c can guide the washing water flowing in from the first water inlet 936 to the first filter inlet 951.

[0352] When the impeller 2 rotates in the first direction, the second guide section 9211c guides the washing water entering the bracket body 920 through the first water inlet 936 to the first filter inlet 951 in a direction away from the wall of the inner drum 1 and close to the center of the inner drum 1.

[0353] The second guide section 9211c may be the portion of the first guide portion 9211 that directs wash water to the first filter inlet 951, thereby ensuring that wash water entering the filter device 9 along the circumference of the inner drum 1 is effectively guided to the first filter inlet 951. In this way, lighter hair and lint that tend to float in the upper layer of the wash water and are difficult to sink can flow with the wash water into the first filter inlet 951 of the filter box 97 and be collected inside the filter box 97, thereby improving the filter device 9's ability to collect lighter hair and lint that are difficult to sink.

[0354] Thus, a filter device 9 is provided within the pulsator washing machine 100. A first water inlet 936 is provided on the side of the filter device 9. The first water inlet 936 is connected to the washing chamber 11 along the circumference of the inner drum 1, thereby allowing wash water to enter the filter device 9 from the circumference of the inner drum 1. When the pulsator 2 rotates in a first direction, lighter hair floating on the upper layer of the wash water flows through the first water inlet 936 toward the first guide portion 9211. The second guide section 9211c of the first guide portion 9211 guides the wash water entering through the first water inlet 936 in a direction away from the wall of the inner drum 1 and toward the center of the inner drum 1. The wash water then flows through the second guide section 9211c into the first filter inlet 951 of the filter box 97, where it is filtered and the hair is collected, thereby filtering the wash water.

[0355] In some embodiments, as Figure 30 As shown, the second guide section 9211c can be a concave arc surface. The second guide section 9211c is constructed as a concave arc surface. When the washing water flows through the concave arc surface, the washing water will flow along the concave arc surface, so that the washing water forms a Coanda effect during the flow.

[0356] Based on the Coanda effect, the washing water flows along the second guide section 9211c, thereby effectively flowing the washing water along the second guide section 9211c to the first filter inlet 951. While improving the flow efficiency of the washing water, it also enhances the ability of the filter device 9 to collect hair debris.

[0357] In some embodiments, the second guide section 9211c may be a smooth surface, on which the washing water is more likely to form a Coanda effect.

[0358] In some embodiments, as Figure 30 As shown, the curvature of the second guide section 9211c is θ, which satisfies the following: θ < 42°. When θ is less than 42°, the second guide section 9211c forms a relatively smooth and continuous curved surface, making it easier for wash water to form a Coanda effect on the second guide section 9211c. This also reduces adverse effects such as water flow dispersion, vortex formation, or flow change caused by an excessively large curvature of the second guide section 9211c.

[0359] If θ is too large, for example, θ>42°, the second guide section 9211c may become steep, which will be unfavorable for the formation of the Coanda effect of the washing water on the second guide section, and the washing water may not flow smoothly along the second guide section 9211c.

[0360] Specifically, the arc angle θ of the second guide segment 9211c can be 34°, 36°, 38°, 40° or 41°.

[0361] In some embodiments, the curvature of the second guide section 9211c is θ, where θ satisfies the following: θ > 29°. When θ is greater than 29°, the length of the second guide section 9211c can be appropriately reduced to prevent the second guide section 9211c from being too flat, thereby prolonging the time the wash water flows through the second guide section 9211c. Having a suitable curvature of the second guide section 9211c can improve diversion efficiency. Wash water can quickly flow into the first filter inlet 951 through the appropriately curved second guide section 9211c, thereby improving the filtration efficiency of the filter device 9.

[0362] It can be understood that if θ is too small, for example: θ<29°, the second guide section 9211c may be too flat, which may prolong the time that the washing water flows on the second guide section 9211c and affect the guide efficiency of the second guide section 9211c.

[0363] Specifically, the arc θ of the second guide section 9211c can be 30°, 31°, 33°, or 34°. In this way, the guide effect of the second guide section 9211c can be taken into account while the guide efficiency of the second guide section 9211c can be improved.

[0364] In some embodiments, the arc angle θ of the second guide segment 9211 c may be any value between 29° and 42°, so as to take into account both the guide effect and the guide efficiency of the second guide segment 9211 c.

[0365] In some embodiments, as Figure 23 、 Figure 24 、 Figure 29 and Figure 30 As shown, the bracket body 920 may include a second water inlet 937. The second water inlet 937 and the first water inlet 936 are located on opposite sides of the bracket body 920 along the circumference of the inner tub 1. The second water inlet 937 is connected to the washing chamber 11 and the guide bracket 92 along the circumference of the inner tub 1.

[0366] In some embodiments, the second water inlet 937 can be symmetrically arranged with respect to the first water inlet 936 relative to the center line of the filter device 9 along the axial direction of the inner cylinder 1 .

[0367] When the pulsator 2 rotates in the first direction, the washing water can enter the support body 920 through the first water inlet 936. When the pulsator 2 rotates in the second direction, the washing water can enter the support body 920 through the second water inlet 937. In this way, whether the pulsator 2 rotates in the first direction or the second direction, it is ensured that the washing water enters the support body 920 and then enters the first filter inlet 951, thereby fully filtering the washing water and improving the filtering effect.

[0368] In some embodiments, as Figure 29 and Figure 30 As shown, the air guide bracket 92 may include a second air guide portion 9212. The second air guide portion 9212 is connected to the bracket body 920 and is arranged along the circumference of the inner tube 1 together with the first air guide portion 9211.

[0369] In some embodiments, the second guide portion 9212 is connected to the first guide portion 9211. The second guide portion 9212 and the first guide portion 9211 can be integrally formed, and the first guide portion 9211 and the second guide portion 9212 can support each other to further ensure the structural strength of the first guide portion 9211 and the second guide portion 9212.

[0370] In some embodiments, the second guide portion 9212 may include a second guide surface 9212a. The second guide surface 9212a is a surface of the second guide portion 9212 that contacts and guides wash water, and the second guide portion 9212 faces away from the wall of the inner drum 1.

[0371] The second guide portion 9212 includes two ends far away from each other along the circumference of the inner drum 1, namely a first end and a second end. The first end of the second guide portion 9212 is closer to the second water inlet 937 than the second end, so that the first end of the second guide surface 9212a first contacts the washing water flowing in from the second water inlet 937.

[0372] The second end of the second guide portion 9212 is closer to the first filter inlet 951 than the first end. Since the washing water flows along the second guide surface 9212a, the first guide surface 9211a can guide the washing water flowing along the second guide surface 9212a to the first filter inlet 951.

[0373] In some embodiments, the first end of the second guide surface 9212a is closer to the wall of the inner tube 1 than the second end, and the second end of the second guide surface 9212a is closer to the center of the inner tube 1 than the first end.

[0374] The second water inlet 937 is arranged close to the wall of the inner drum 1, and the first filter inlet 951 is closer to the center of the inner drum 1 than the second water inlet 937. Therefore, the second end of the second guide portion 9212 is closer to the center of the inner drum 1 than the first end, thereby being able to guide the washing water flowing in from the second water inlet 937 to the first filter inlet 951.

[0375] In this way, no matter whether the impeller 2 rotates along the first direction or the second direction, the first guide part 9211 and the second guide part 9212 can guide the washing water, so that the washing water can be guided to the first filter inlet 951 of the filter box 97 regardless of whether it flows along the first direction or the second direction, to ensure that the filter device 9 filters the washing water.

[0376] In some embodiments, the second guide surface 9212a includes a concave arc surface. The second guide surface 9212a is configured to include a concave arc surface. When the wash water flows through the concave arc surface, the wash water flows along the concave arc surface to form a Coanda effect.

[0377] Based on the Coanda effect, the washing water flows along the second guide surface 9212a, so that the second guide surface 9212a can effectively guide the washing water to the first filter inlet 951. While improving the flow efficiency of the washing water, it also enhances the ability of the filter device 9 to collect hair debris.

[0378] Specifically, please refer to the description that the first guide surface 9211a includes a second guide section 9211c constructed as a concave arc surface. The second guide section 9211c is a concave arc surface. The second guide portion 9212 and the first guide portion 9211 can have the same structure, so the content that the second guide surface 9212a includes a concave arc surface will not be repeated here.

[0379] In some embodiments, the second guide surface 9212a can be symmetrically arranged with respect to the first guide surface 9211a with respect to the connecting line 9213 between the two.

[0380] In this way, the guiding effects of the first guide portion 9211 and the second guide portion 9212 can be balanced, and when the pulsator 2 rotates along the first direction or the second direction, the washing water can be effectively guided into the first filter inlet 951.

[0381] It should be noted that the maximum water level in a pulsator washing machine 100 is typically no higher than the bottom edge of the balance ring 13. Otherwise, wash water, driven by the pulsator 2, would easily overflow the inner drum 1. Because hair is relatively light, it will remain a certain distance from the bottom edge of the balance ring 13 even when the pulsator washing machine 100 is operating at a high water level.

[0382] In some embodiments, as Figure 27 and Figure 28 As shown, along the axial direction of the inner tube 1 , the first water inlet 936 may have a first preset height H1 , and the lower edge of the balance ring 13 to the lower edge of the inner tube 1 has a second preset height H2 , and H1 and H2 satisfy: H1 / H2>0.2.

[0383] H1 / H2>0.2, so that the first water inlet 936 can cover as much as possible the largest range of the inner drum 1 of the pulsator washing machine 100 along the axial direction of the inner drum 1. In this way, no matter the washing water is at a higher water level or a lower water level, the hair floating on the upper layer of the washing water can enter the first water inlet 936 with the washing water, and enter the filter box 97 to complete filtration, thereby ensuring the filtering effect of the filter device 9.

[0384] If H1 / H2 is too small, for example, H1 / H2 is less than 0.2, the axial length of the first water inlet 936 along the inner drum 1 may be too short, which may cause the first water inlet 936 to be unable to effectively cover a larger range of the inner drum 1, especially when the washing water is at a higher water level or a lower water level, the first water inlet 936 may not be able to effectively cover the upper layer of the washing water, and then the first water inlet 936 may not be able to effectively collect the hair located in the upper layer of the washing water, thereby affecting the filtering effect of the filter device 9.

[0385] Illustratively, H1 / H2 may be 0.21, 0.23, 0.25, 0.3, 0.4, or 0.5.

[0386] In some embodiments, along the axial direction of the inner tube 1 , the first water inlet 936 may have a first preset height H1 , and the lower edge of the balance ring 13 to the lower edge of the inner tube 1 has a second preset height H2 , and H1 and H2 satisfy: H1 / H2<0.8.

[0387] The first water inlet 936 is primarily used to collect hair located above the filtered water. It covers as wide an axial extent as possible within the inner drum 1, ensuring that the preset height of the first water inlet 936 can accommodate a wide range of possible water levels. However, if the preset height of the first water inlet 936 is too high, it may result in unnecessary space occupation and material waste. Therefore, H1 / H2 < 0.8 allows for a preset height of the first water inlet 936 that balances the water inflow from the side of the support body 920 while preventing the first water inlet 936 from excessively occupying the washing chamber 11.

[0388] Illustratively, H1 / H2 may be 0.5, 0.6, 0.7, 0.75, or 0.78.

[0389] It is understandable that if the axial length of the first water inlet 936 along the inner drum 1 is too long, such as H1 / H2>0.8, the first water inlet 936 may be too long, resulting in unnecessary waste of space in the washing chamber.

[0390] In some embodiments, the bracket body 920 may include a through-hole 9204, which is used to allow relatively large hair debris at the bottom of the washing chamber 11, or hair carried to the bottom of the washing chamber 11 by the surging wash water, to enter the filter chamber 971 along with the wash water through the second filter inlet 952 at the bottom of the filter cartridge 97. This will be described in detail later. If the first predetermined axial height of the first water inlet 936 is too long, it will occupy the space provided by the through-hole 9024, thereby reducing the flow rate of wash water entering from the bottom of the filter device 9 and affecting the filtering effect of the filter device 9.

[0391] In some embodiments, H1 / H2 may be any value between 0.21 and 0.78. While taking into account the water intake of the first water inlet 936, it is desirable to avoid the first water inlet 936 being too long, which would cause the filter device 9 to occupy too much space in the washing chamber 11.

[0392] In some embodiments, as Figure 27 and Figure 28 As shown, the first water inlet 936 has a first preset height H1 along the axial direction of the inner cylinder 1, and along the axial direction of the inner cylinder 1, the lower edge of the balance ring 13 to the lower edge of the bottom cover 14 of the inner cylinder 1 has a sixth preset height H6, and H1 and H6 satisfy: H1 / H6>0.25.

[0393] A sixth predetermined height H6, from the lower edge of the balancing ring 13 to the lower edge of the bottom cover 14 of the inner drum 1, defines the effective height range of the washing chamber 11 and determines the maximum amount of wash water that the pulsator washing machine 100 can hold, i.e., the maximum water level. A value of H1 / H6 greater than 0.25 ensures that the first water inlet 936 covers a sufficiently large predetermined height of the inner drum assembly 12, allowing the first water inlet 936 to effectively collect hair at both high and low wash water levels.

[0394] If H1 / H6 is too small, such as H1 / H6<0.25, the axial length of the first water inlet 936 along the inner drum 1 may be too short, which may cause the first water inlet 936 to be unable to effectively cover a larger axial range of the inner drum 1 component 12, especially when the washing water is at a higher water level or a lower water level, the first water inlet 936 may not be able to effectively cover the upper layer of the washing water, and then the first water inlet 936 may not be able to effectively collect the hair located in the upper layer of the washing water, thereby affecting the filtering effect of the filter device 9.

[0395] Illustratively, H1 / H6 may be 0.26, 0.3, 0.35, 0.4, 0.45 or 0.5.

[0396] In some embodiments, the first water inlet 936 has a first preset height H1 along the axial direction of the inner cylinder 1, and along the axial direction of the inner cylinder 1, the lower edge of the balance ring 13 to the lower edge of the bottom cover 14 of the inner cylinder 1 has a sixth preset height H6, and H1 and H6 satisfy: H1 / H6<0.75.

[0397] The first water inlet 936 can cover as wide an axial range of the inner drum 1 as possible to ensure that the preset height of the first water inlet 936 can accommodate a wide range of possible water levels. However, if the preset height of the first water inlet 936 is too long, it may cause unnecessary space occupation and waste of materials. Therefore, H1 / H6<0.75, so that the preset height of the first water inlet 936 can take into account the water inflow from the side of the bracket body 920 while preventing the first water inlet 936 from excessively occupying the space of the washing chamber 11. For example, H1 / H6 can be 0.55, 0.6, 0.65, 0.7, or 0.74.

[0398] It is understandable that if the axial length of the first water inlet 936 along the inner drum 1 is too long, such as H1 / H6>0.75, the first water inlet 936 may be too long, resulting in unnecessary waste of space in the washing chamber.

[0399] For example, in some embodiments, the support body 920 may include a through-hole 9204. This through-hole 9204 is used to allow relatively heavy hair debris at the bottom of the washing chamber 11, or hair carried to the bottom of the washing chamber 11 by the surging wash water, to enter the filter chamber 971 along with the wash water through the second filter inlet 952 at the bottom of the filter box 97. This will be described in detail later. Therefore, the first predetermined axial height of the first water inlet 936 should not be too large to ensure that the through-hole 9204 is located at a sufficient height within the inner drum 1 to allow the wash water to enter the filter chamber 971 from the bottom of the filter device 9.

[0400] In some embodiments, H1 / H6 can be any value between 0.26 and 0.74. While taking into account the water intake of the first water inlet 936, it is best to avoid the first water inlet 936 being too long, which would cause the filter device 9 to occupy too much space in the washing chamber 11.

[0401] In some embodiments, as Figure 28 As shown, there is a third preset height H3 between the upper edge of the first water inlet 936 and the lower edge of the balance ring 13, and the third preset height H3 satisfies: H3>20mm.

[0402] Since the higher water level of the washing water in the washing chamber 11 is at a certain distance from the lower edge of the balance ring 13, H3>20mm, it can ensure that the upper edge of the first water inlet 936 is as close as possible to the lower edge of the balance ring 13, so as to be able to collect dander and hair in the washing water at a higher water level, but not too close to the lower edge of the balance ring 13, so as to avoid unnecessary space occupation and material waste by the filter device 9.

[0403] If the upper edge of the first water inlet 936 is too close to the lower edge of the balance ring 13, it means that the filter device 9 is too close to the lower edge of the balance ring 13. For example, when H3 is less than 20 mm, the filter device 9 may be too close to the balance ring, and the vibration amplitude of the balance ring 13 is large, which may affect the installation stability of the filter device 9 and easily cause the hair and lint collected in the filter box 97 to flow back to the washing chamber 11 under vibration.

[0404] For example, the third preset height H3 between the upper edge of the first water inlet 936 and the lower edge of the balance ring 13 may be 21 mm, 30 mm, 40 mm, 50 mm, 80 mm or 100 mm.

[0405] In some embodiments, as Figure 28 As shown, there is a third preset height H3 between the upper edge of the first water inlet 936 and the lower edge of the balance ring 13, and the third preset height H3 satisfies: H3<300mm.

[0406] The distance between the upper edge of the first water inlet 936 and the lower edge of the balance ring 13 should not be too large. For example, when H3>300 mm, the first water inlet 936 may not be able to effectively collect the hair on the upper layer of the washing water.

[0407] It is understood that since the capacity of the pulsator washing machine 100 varies, the size of the inner drum assembly 12 also varies. Therefore, H3 < 300 mm ensures that even in a larger capacity pulsator washing machine 100, the first water inlet 936 of the filter device 9 can still be relatively close to the upper edge of the balance ring 13, so that the first water inlet 936 can effectively collect more hair located in the upper layer of the wash water. For example, the third predetermined height H3 between the upper edge of the first water inlet 936 and the lower edge of the balance ring 13 can be 150 mm, 200 mm, 220 mm, 240 mm, 250 mm, 280 mm, 290 mm, or 299 mm.

[0408] In some embodiments, the third predetermined height H3 between the upper edge of the first water inlet 936 and the lower edge of the gimbal 13 can be any value between 21 mm and 299 mm. While taking into account the water intake of the first water inlet 936, it is also desirable to avoid the first water inlet 936 being too close to the gimbal 13, thereby preventing the filter device 9 from vibrating excessively and affecting the hair collection effect.

[0409] In some embodiments, there is a fourth preset height H4 between the lower edge of the first water inlet 936 and the lower edge of the bottom cover 14 of the inner cylinder 1 , and the fourth preset height H4 satisfies: H4>100 mm.

[0410] Since the first water inlet 936 is mainly used to collect hair and light lint located in the upper layer of the washing water, the first water inlet 936 may not be too close to the lower edge of the bottom cover 14 of the inner drum 1. When H4>100mm, it can ensure that the first water inlet 936 can collect hair and lint located in the upper layer of the washing water, and can also avoid unnecessary space occupation and material waste of the filter device 9.

[0411] It is understandable that if the distance between the first water inlet 936 and the lower edge of the bottom cover 14 of the inner drum 1 is too short, such as H4 < 100 mm, the first water inlet 936 may be too long, resulting in unnecessary waste of space in the washing chamber.

[0412] In some embodiments, the support body 920 may include a through-hole 9204, which is used to allow relatively heavy hair debris at the bottom of the washing chamber 11, or hair carried to the bottom of the washing chamber 11 by the surging wash water, to enter the filter chamber 971 along with the wash water through the second filter inlet 952 at the bottom of the filter cartridge 97. This will be described in detail later. If the first water inlet 936 is too close to the lower edge of the bottom cover 14 of the inner drum 1, it will occupy the space provided by the through-hole 9024, thereby reducing the flow rate of wash water entering from the bottom of the filter device 9 and affecting the filtering effect of the filter device 9.

[0413] For example, the fourth preset height H4 between the lower edge of the first water inlet 936 and the lower edge of the bottom cover 14 of the inner cylinder 1 may be 101 mm, 130 mm, 150 mm, 180 mm or 200 mm.

[0414] In some embodiments, there is a fourth preset height H4 between the lower edge of the first water inlet 936 and the lower edge of the bottom cover 14 of the inner cylinder 1 , and the fourth preset height H4 satisfies: H4<300 mm.

[0415] If the lower edge of the first water inlet 936 is too far away from the bottom cover 14 of the inner drum 1, such as when H4>300mm, the first water inlet 936 may not be able to effectively collect hair and lint located in the upper layer of the washing water when the pulsator washing machine 100 is operating at a lower water level. Therefore, when H4<300mm, it can be ensured that the first water inlet 936 can still collect hair and lint located in the upper layer of the washing water when the pulsator washing machine 100 is operating at a lower water level, so as to ensure the filtering effect of the filter device 9.

[0416] For example, the fourth preset height H4 between the lower edge of the first water inlet 936 and the lower edge of the bottom cover 14 of the inner cylinder 1 may be 220 mm, 240 mm, 260 mm, 280 mm or 299 mm.

[0417] In some embodiments, the fourth predetermined height H4 between the lower edge of the first water inlet 936 and the lower edge of the bottom cover 14 of the inner drum 1 can be any value between 101 mm and 299 mm. This is to ensure that the water intake of the first water inlet 936 is taken into consideration while minimizing the first water inlet 936 from occupying too much space in the washing chamber 11.

[0418] In some embodiments, as Figure 27 and Figure 28 As shown, the width of the filter device 9 is D1, the circumference of the inner cylinder 1 is D2, and D1 and D2 satisfy: D1 / D2>0.05.

[0419] D1 / D2>0.05, the width of the filter device 9 can be the length of the filter device 9 extending along the circumference of the inner drum 1. The width of the filter device 9 needs to have a certain width, so as to ensure that the filter device 9 has sufficient space to guide and filter the washing water, and collect the collected hair and lint in the filter device 9.

[0420] It is understandable that if D1 / D2 is less than 0.05, the filter device 9 may be too narrow, which may cause the filter box 97 to be easily fully loaded, requiring frequent disassembly and cleaning of the filter box 97 .

[0421] Illustratively, D1 / D2 may be 0.06, 0.07, 0.1, 0.13, 0.15, 0.18, or 0.2.

[0422] In some embodiments, the width of the filter device 9 is D1, the circumference of the inner cylinder 1 is D2, and D1 and D2 satisfy: D1 / D2<0.3.

[0423] D1 / D2<0.3, can ensure that the filter device 9 has a certain width to effectively guide and filter the washing water, and can also ensure that the filter device 9 does not occupy too much space in the inner drum 1, so as to avoid unnecessary space occupation and material waste caused by the filter device 9.

[0424] If the ratio D1 / D2 is too large, for example, D1 / D2 > 0.3, the filter device 9 may excessively occupy the space of the washing chamber, affecting the washing effect of the pulsator washing machine 2 .

[0425] Illustratively, D1 / D2 may be 0.22, 0.24, 0.26, 0.28, or 0.29.

[0426] In some embodiments, D1 / D2 may be any value between 0.06 and 0.29, so as to take into account both the filtering effect of the filter device 9 and the space occupied by the filter device 9 in the washing chamber 11, and to save the manufacturing cost of the filter device 9.

[0427] In some embodiments, as Figure 27 and Figure 28 As shown, the guide bracket 92 has a fifth preset height H5 along the axial direction of the inner tube 1, and along the axial direction of the inner tube 1, the lower edge of the balance ring 13 to the lower edge of the bottom cover 14 of the inner tube 1 has a sixth preset height H6, and H5 and H6 satisfy: H5 / H6>0.5.

[0428] H5 / H6>0.5, so that the guide bracket 92 can cover as much of the space of the inner drum 1 assembly 12 as possible in the axial direction, so as to ensure the guide efficiency of the guide bracket 92 and ensure that as much washing water as possible enters the guide bracket 92 to effectively collect hair and lint in the washing water.

[0429] Since the guide bracket 92 includes a first water inlet 936 and a through-port 9204 at the bottom, that is, the washing water can enter the guide bracket 92 from the side and bottom of the guide bracket 92, if the axial length of the guide bracket 92 along the inner drum 1 is too short, for example, H5 / H6<0.5, it may cause the guide bracket 92 to be unable to take into account both the side water inlet and the bottom water inlet. For example, when the pulsator washing machine 2 is operating at a higher water level, the first water inlet 936 cannot collect the hair located on the upper layer of the washing water, or when the pulsator washing machine 2 is operating at a lower water level, the through-port 9204 is higher than the water level line, affecting the guide effect of the guide bracket 92.

[0430] Illustratively, H5 / H6 may be 0.6, 0.55, 0.6, 0.66 or 0.7.

[0431] In some embodiments, the guide bracket 92 has a fifth preset height H5 along the axial direction of the inner cylinder 1, and along the axial direction of the inner cylinder 1, the lower edge of the balance ring 13 to the lower edge of the bottom cover 14 of the inner cylinder 1 has a sixth preset height H6, and H5 and H6 satisfy: H5 / H6<0.95.

[0432] H5 / H6<0.95, which can not only make the guide bracket 92 cover as much of the space of the inner cylinder 1 assembly 12 as possible in the axial direction, but also ensure a certain distance between the guide bracket 92 and the bottom cover 14 of the inner cylinder 1, so that the through hole 9204 at the bottom of the guide bracket 92 and the bottom cover 14 of the inner cylinder 1 have a certain distance, so that the washing water at the bottom of the washing chamber 11 enters the guide bracket 92 from the through hole 9204, and at the same time avoid H5 / H6 being too large, for example, when H5 / H6>0.95, unnecessary space occupation and material waste caused by the filter device 9 can be avoided.

[0433] Illustratively, H5 / H6 may be 0.7, 0.75, 0.8, 0.85, 0.9 or 0.94.

[0434] In some embodiments, H5 / H6 may be any value between 0.6 and 0.94, so as to take into account both the diversion effect of the diversion bracket 92 and the space occupied by the diversion bracket 92 in the washing chamber 11 .

[0435] In some embodiments, as Figure 18 As shown, the guide bracket 92 has a fifth preset height H5 along the axial direction of the inner tube 1 , and the filter box 97 has a seventh preset height H7 along the axial direction of the inner tube 1 , and H7 and H5 satisfy: H7 / H5>0.5.

[0436] H7 / H5>0.5, the filter box 97 can occupy as much space of the guide bracket 92 as possible to ensure that the washing water can be filtered through the filter box 97, and to ensure that hair and lint can be effectively collected in the filter box 97, so as to improve the filtering capacity of the filter device 9.

[0437] It is understood that if the filter box 97 is too small, for example, H7 / H5 < 0.5, the filter box 97 may frequently become fully loaded, meaning that the filter box 97 is easily filled with hair, lint, etc., and blocks the filter screen 911. Furthermore, the wash water may not be filtered by the too-short filter box 97, thereby affecting the filtration capacity of the filter box 97. Furthermore, if the axial length of the filter box 97 is too small and the axial length of the flow guide bracket 92 is too large, the flow guide bracket 92 will unnecessarily occupy space in the washing chamber 11.

[0438] Illustratively, H7 / H5 may be 0.51, 0.55, 0.6, 0.66 or 0.7.

[0439] In some embodiments, as Figure 18 As shown, the guide bracket 92 has a fifth preset height H5 along the axial direction of the inner tube 1 , and the filter box 97 has a seventh preset height H7 along the axial direction of the inner tube 1 , and H7 and H5 satisfy: H7 / H5<0.9.

[0440] Since the top and bottom of the filter box 97 can be detachably mounted to the flow guide bracket 92, H7 / H5 < 0.9 can ensure that there is reserved space at the top and bottom of the flow guide bracket 92 for mounting the filter box 97, thereby ensuring the installation stability of the filter box 97. If H7 / H5 is too large, for example, H7 / H5 > 0.9, it may affect the installation and fixation of the filter box 97 by the flow guide bracket 92, affecting the installation stability of the filter box 97.

[0441] Illustratively, H7 / H5 may be 0.7, 0.75, 0.8, 0.85, or 0.89.

[0442] In some embodiments, H7 / H5 may be any value between 0.51 and 0.89, so as to take into account both the filtering effect of the filter box 97 and the installation stability between the filter box 97 and the flow guide bracket 92.

[0443] In some embodiments, as Figure 26 、 Figure 31 、 Figure 34 and Figure 35 As shown, the cassette body 970 may include a first housing 95 . A first filter inlet 951 may be formed in the first housing 95 .

[0444] In some embodiments, as Figure 25As shown, the box body 970 may include a second shell 93. The second shell 93 is connected to the first shell 95 and defines the above-mentioned filter cavity 971. The second shell 93 is farther away from the cylinder wall of the inner cylinder 1 than the first shell 95, and the above-mentioned filter cavity outlet 931 is formed in the second shell 93.

[0445] The first shell 95 and the second shell 93 can be a split structure, so that when the filter box 97 is removed from the bracket body 920, the first shell 95 can be separated from the second shell 93, thereby conveniently removing the hair and lint collected in the filter cavity 971.

[0446] In some embodiments, as Figure 30 and Figure 31 As shown, the first housing 95 may include a flow blocking portion 9511. The first end of the flow blocking portion 9511 is connected to the edge of the first filter inlet 951, and the second end of the flow blocking portion 9511 extends toward the second housing 93. In this way, the wash water flowing into the first filter inlet 951 can be blocked by the flow blocking portion 9511 to prevent the wash water from flowing back through the first filter inlet 951, thereby ensuring the filtering effect of the filter device 9.

[0447] At the same time, the baffle 9511 extends toward the second shell 93 and can also stop and limit the hair and lint collected in the filter box 97. It is equivalent to the baffle 9511 being able to hold the hair and lint to prevent them from flowing out of the filter cavity 971 through the first filter inlet 951.

[0448] In some embodiments, as Figure 29 As shown, the first filter inlet 951 may include a first edge 9512. The first edge 9512 extends along the axial direction of the inner tub 1, that is, along the height direction of the pulsator washing machine 100.

[0449] In some embodiments, as Figure 29 As shown, the first filter inlet 951 may include a second edge 9513. The second edge 9513 extends along the axial direction of the inner cylinder 1 and is arranged opposite to the first edge 9512 along the circumferential direction of the inner cylinder 1.

[0450] As can be seen, the first filter inlet 951 extends along the axial direction of the inner drum 1, that is, the first filter inlet 951 has a certain length along the axial direction of the inner drum 1. In addition, the length of the first flow guide 9211 along the axial direction of the inner drum 1 can be adapted to the length of the first filter inlet 951, so that more wash water can enter the first filter inlet 951 through the guidance of the first flow guide 9211.

[0451] In some embodiments, as Figure 29As shown, the baffle portion 9511 may include a first baffle wall 9514 . A first end of the first baffle wall 9514 is connected to the first edge 9512 , and a second end of the first baffle wall 9514 extends toward the second housing 93 .

[0452] In some embodiments, as Figure 29 As shown, the baffle portion 9511 may include a second baffle wall 9515 . A first end of the second baffle wall 9515 is connected to the second edge 9513 , and a second end of the second baffle wall 9515 extends toward the second housing 93 .

[0453] In this way, even if the washing water entering the filter cavity 971 through the first filter inlet 951 tends to flow back out of the filter cavity 971 through the first filter inlet 951, the first baffle wall 9514 and the second baffle wall 9515 can form a comprehensive shielding along both sides of the circumference of the inner drum 1, thereby further enhancing the anti-backflow effect of the baffle part 9511.

[0454] In some embodiments, the second baffle wall 9515 is farther away from the first end of the first guide surface 9211 a than the first baffle wall 9514 , and the second end of the second baffle wall 9515 is located on an extension of the first guide surface 9211 a .

[0455] It should be noted that the extended surface of the first guide surface 9211a refers to a virtual surface extending from the current boundary of the first guide surface 9211a along its guide direction. The extended surface of the first guide surface 9211a can be tangent to the second end of the second guide section 9211c.

[0456] Although the second baffle 9515 extends a certain distance toward the second housing 93 to prevent backflow of wash water, the end of the second baffle 9515 closest to the second housing 93 is located on an extension of the first guide surface 9211a. In other words, the second baffle 9515 does not block the wash water flowing along the first guide surface 9211a. The wash water can continue to flow into the filter chamber 971 along the direction of the first guide surface 9211a, thereby preventing turbulence in the wash water before entering and within the filter box 97, which would reduce the filtering effect.

[0457] It can be understood that when the washing water is in a turbulent state, the flow direction may be chaotic and the flow rate of the washing water may be uneven, which may cause the hair or hair debris in the washing water to be unable to effectively enter the filter chamber 971 due to the chaotic flow path, or easily flow back from the filter chamber 971, thereby reducing the filtering effect of the filter device 9. Therefore, it is necessary to minimize the turbulence and eddy current of the washing water before entering the filter chamber 971 and in the filter chamber 971.

[0458] In some embodiments, as Figure 29As shown, the first baffle wall 9514 is further away from the first end of the second guide portion 9212 than the second baffle wall 9515, and the second end of the first baffle wall 9514 is located on an extension of the second guide surface 9212a. This also serves the purpose of preventing the first baffle wall 9514 from blocking the water flow introduced by the second guide surface 9212a, which will not be further described here.

[0459] In some embodiments, as Figure 29 As shown, the second end of the second baffle wall 9515 can be away from the extended surface of the first guide surface 9211a in the direction away from the first baffle wall 9514, so that the second baffle wall 9515 is further away from the extended surface of the first guide surface 9211a to avoid blocking the washing water, so as to minimize the turbulence and eddy current of the washing water before entering the filter chamber 971 and in the filter chamber 971.

[0460] In some embodiments, as Figure 29 As shown, the first guide surface 9211a may include two ends along the circumference of the inner cylinder 1. The first end of the first guide surface 9211a may be an end away from the first filter inlet 951 along the radial direction of the inner cylinder 1, and the second end of the first guide surface 9211a may be an end close to the first filter inlet 951 along the radial direction of the inner cylinder 1.

[0461] In some embodiments, the second end of the first guide surface 9211a coincides with the second end 9211c2 of the second guide segment 9211c.

[0462] In some embodiments, the second end of the first guide surface 9211 a is located close to the first filter inlet 951 and is flush with the plane where the first edge 9512 and the second edge 9513 are located.

[0463] The plane where the first edge 9512 and the second edge 9513 are located defines the position of the first filter inlet 951. As described above, the second end of the first guide surface 9211a is close to the first filter inlet 951, and the second end of the first guide surface 9211a is flush with the plane where the first edge 9512 and the second edge 9513 are located, thereby ensuring that the first guide portion 9211 will not extend into the first filter inlet 951 and occupy the space of the first filter inlet 951, thereby ensuring the flow rate of washing water entering the filter device 9.

[0464] In some embodiments, as Figure 37 As shown, the surface of the first shell 95 forming the first edge 9512 and the second edge 9513 can be a first outer surface 957, and the first outer surface 957 can be configured as a curved surface. In this way, the surface of the box body 970 facing the first guide portion 9211 and the second guide portion 9212 is a curved surface, which is less likely to interfere with the flow direction and flow rate of the water.

[0465] In some embodiments, as Figure 29 and Figure 35 As shown, the box body 970 may include a first outer surface 957. The first outer surface 957 is the surface of the box body 970 facing the bracket body 920. That is, the first outer surface 957 is the surface of the first shell 95 facing the bracket body 920, and the first filter inlet 951 is provided on the first outer surface 957.

[0466] In some embodiments, the second end of the first guide surface 9211 a is flush with the first outer surface 957 of the box body 970 .

[0467] In some embodiments, as Figure 29 As shown, the first outer surface 957 can be configured as a planar surface.

[0468] The second end of the first guide surface 9211a is flush with the plane of the first outer surface 957, which can ensure that the first guide portion 9211 does not extend into the first filter inlet 951 and occupy the space of the first filter inlet 951, thereby ensuring the flow rate of washing water entering the filter device 9.

[0469] In some embodiments, the first guide portion 9211 can guide the wash water from the first water inlet 936 to an end of the first outer surface 957 close to the first filter inlet 951 .

[0470] The first guide portion 9211 guides the wash water entering from the first water inlet 936 to the first outer surface 957, on which the first filter inlet 951 is provided. The first guide portion 9211 guides the water toward the end of the first outer surface 957 where the first filter inlet 951 is formed. The water can enter the filter cavity 971 through the first filter inlet 951 due to the Coanda effect or inertia, thereby ensuring the diversion effect of the first guide portion 9211 and thus the filtering effect of the filter device 9.

[0471] In some embodiments, as Figure 30 As shown, the second end of the first guide surface 9211 a is located close to the first filter inlet 951 and has a second preset distance L4 from the plane where the first edge 9512 and the second edge 9513 are located.

[0472] A second predetermined distance L4 is defined between the second end of the first flow-guiding surface 9211a and the plane containing the first edge 9512 and the second edge 9513. This ensures that the first flow-guiding portion 9211 does not extend into the first filter inlet 951 and occupy the space therein, thereby ensuring the flow rate of wash water entering the filter device 9. Furthermore, despite the certain distance between the first flow-guiding portion 9211 and the first filter inlet 951, wash water flowing along the first flow-guiding portion 9211 can continue to flow in the diversion direction due to the Coanda effect or inertia and enter the first filter inlet 951, thereby ensuring the diversion effect of the first flow-guiding portion 9211.

[0473] In some embodiments, as Figure 30 As shown, there is a second preset distance L4 between the second end of the first guide surface 9211a and the first outer surface 957 of the box body 970. The first outer surface 957 can be a plane.

[0474] A second predetermined distance L4 is provided between the second end of the first flow-guiding surface 9211a and the first outer surface 957. This ensures that the first flow-guiding portion 9211 does not extend into the first filter inlet 951 and occupy the space therein, thereby ensuring the flow rate of wash water entering the filter device 9. Furthermore, despite the certain distance between the first flow-guiding portion 9211 and the first outer surface 957, wash water flowing along the first flow-guiding portion 9211 can continue to flow in the diversion direction due to the Coanda effect or inertia and enter the first filter inlet 951, thereby ensuring the diversion effect of the first flow-guiding portion 9211.

[0475] In some embodiments, the second preset distance L4 may satisfy: L4<5 mm.

[0476] It is understood that the distance between the second end of the first guide surface 9211a and the first outer surface 957 should not be too large, nor should the distance between the second end of the first guide surface 9211a and the plane containing the first edge 9512 and the second edge 9513 be too large. If the second predetermined distance L4 is too large, such as L4 > 5 mm, wash water flowing along the first guide portion 9211 may flow toward the second guide portion 9212 and out of the second water inlet 937, rather than entering the first filter inlet 951, thereby affecting the diversion effect of the first guide portion 9211.

[0477] Specifically, the second preset distance L4 can be 0.5 mm, 0.8 mm, 1.1 mm, 1.4 mm, 1.7 mm, 2.0 mm, 2.3 mm, 2.6 mm, 2.9 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 4.9 mm.

[0478] In some implementations, such as Figure 30As shown, along the arrangement direction of the first shell 95 and the second shell 93 , the baffle 9511 has a first preset length L1 , and the filter cavity 971 has a second preset length L2 , and L1 and L2 satisfy: L1 / L2≤1 / 2.

[0479] The first shell 95 and the second shell 93 may be arranged in the thickness direction of the filter box 97. In this direction, the first predetermined length L1 of the flow block and the second predetermined length L2 of the filter cavity 971 may have an appropriate proportional relationship, such as L1 / L2<1 / 2, to ensure that the flow block 9511 does not extend too far into the filter cavity 971 and occupy the effective filtering area of ​​the filter cavity 971.

[0480] At the same time, the second end of the overly long baffle 9511 may not be located on the extended surface of the first guide surface 9211a. For example, if L1 / L2>1 / 2, the second end of the baffle 9511 may block the washing water flowing into the first filter inlet 951 along the first guide surface 9211a, thereby affecting the flow rate of the washing water entering from the first filter inlet 951.

[0481] Specifically, the ratio between the first preset length L1 and the second preset length L2 may be 0.4, 0.42, 0.44, 0.46, 0.45 or 0.49.

[0482] In some embodiments, as Figure 30 As shown, along the arrangement direction of the first shell 95 and the second shell 93 , the baffle 9511 has a first preset length L1 , and the filter cavity 971 has a second preset length L2 , and L1 and L2 satisfy: L1 / L2 > 1 / 3.

[0483] The first shell 95 and the second shell 93 can be arranged in the direction of the thickness of the filter box 97. In this direction, the first predetermined length L1 of the flow block and the second predetermined length L2 of the filter cavity 971 should have an appropriate proportional relationship, such as L1 / L2>1 / 3. This ensures that the flow block 9511 has a certain length to ensure that the flow block 9511 can achieve the backflow prevention effect. In addition, if the length of the flow block 9511 is too short, for example, L1 / L2<1 / 3, not only will the flow block 9511 fail to achieve its purpose of backflow prevention, but it may also make it difficult for the flow block 9511 to block hair and lint in the filter cavity 971, and the hair and lint will easily flow out of the first filter inlet 951.

[0484] Specifically, the ratio between the first preset length L1 and the second preset length L2 may be 0.34, 0.36, 0.37, 0.38 or 0.4, etc.

[0485] In some embodiments, the ratio between the first preset length L1 and the second preset length L2 can be any value between 0.34 and 0.49.

[0486] In some embodiments, as Figure 30 As shown, along the arrangement direction of the first shell 95 and the second shell 93, there is a first preset distance L3 between the second end of the baffle 9511 and the second shell 93, and the filter cavity 971 has a second preset length L2, and L3 and L2 satisfy: L3 / L2<2 / 3.

[0487] The first shell 95 and the second shell 93 may be arranged in the direction of the thickness of the filter box 97. In this direction, the first predetermined distance L3 between the second end of the flow blocking portion 9511 and the second shell 93 and the second predetermined length L2 of the filter cavity 971 should have an appropriate ratio, such as L3 / L2<2 / 3, to avoid an excessively large distance between the second end of the flow blocking portion 9511 and the second shell 93.

[0488] If the ratio of the distance between the second end of the baffle 9511 and the second shell 93 to the second preset distance L2 of the filter chamber 971 is too large, for example: L3 / L2>2 / 3, that is, if the distance between the second end of the baffle 9511 and the second shell 93 is too long, it will affect the anti-backflow effect of the baffle 9511, and the washing water will more easily flow out of the first filter inlet 951 from the distance between the second end of the baffle 9511 and the second shell 93, and hair and lint will also more easily flow out of the filter chamber 971 from the distance between the second end of the baffle 9511 and the second shell 93.

[0489] Specifically, the ratio between the first preset distance L3 and the second preset length L2 may be 0.49, 0.55, 0.62 or 0.66, etc.

[0490] In some embodiments, as Figure 30 As shown, along the arrangement direction of the first shell 95 and the second shell 93, there is a first preset distance L3 between the second end of the baffle 9511 and the second shell 93, and the filter cavity 971 has a second preset length L2, and L3 and L2 satisfy: L3 / L2>1 / 2.

[0491] The first shell 95 and the second shell 93 may be arranged in the thickness direction of the filter box 97. In this direction, the first predetermined distance L3 between the second end of the flow blocking portion 9511 and the second shell 93 and the second predetermined length L2 of the filter cavity 971 should have an appropriate proportional relationship, L3 / L2>1 / 2, to prevent the distance between the flow blocking portion 9511 and the second shell 93 from being too short.

[0492] Since a filter chamber outlet 931 is provided on the second shell 93, if the distance between the second end of the baffle 9511 and the second shell 93 is too small, for example: L3 / L2<1 / 2, that is, if the distance between the second end of the baffle 9511 and the second shell 93 is too short, the baffle 9511 may block the first filter inlet 951 and the filter chamber outlet 931, that is, the baffle 9511 may block the path of the washing water flowing out of the filter chamber 971, thereby affecting the filtering effect of the filter device 9.

[0493] Specifically, the ratio between the first preset distance L3 and the second preset length L2 may be 0.6, 0.53, 0.55 or 0.6, etc.

[0494] In some embodiments, the ratio between the first preset distance L3 and the second preset length L2 can be any value between 0.6 and 0.66.

[0495] In some embodiments, as Figure 29 and Figure 36 As shown, the first housing 95 may include a first outer surface 957 facing the first guide surface 9211a. The first outer surface 957 is connected to the first edge 9512. A first guide channel 921 is formed between the first outer surface 957 and the first guide surface 9211a. The first guide channel 921 is connected to the first water inlet 936 to guide the wash water.

[0496] It can be understood that the first guide channel 921 is formed between the filter box 97 and the first guide part 9211, and the bracket body 920 can support the filter box 97 so that there is a distance between the filter box 97 and the first guide part 9211, so that the first guide channel 921 for washing water to pass through is formed between the first outer surface 957 and the first guide surface 9211a, thereby ensuring the structural compactness of the filter device 9.

[0497] In some embodiments, as Figure 29 As shown, the first outer surface 957 also faces the second guide portion 9212 along the radial direction of the inner drum 1. The first outer surface 957 is connected to the second edge 9513. A second guide channel 927 is formed between the first outer surface 957 and the second guide surface 9212a. The second guide channel 927 is connected to the second water inlet 937 to guide the wash water.

[0498] It can be understood that the second guide channel 927 is formed between the filter box 97 and the second guide part 9212, and the bracket body 920 can support the filter box 97 so that there is a distance between the filter box 97 and the second guide part 9212. In this way, the first outer surface 957 can also form a second guide channel 927 for washing water to pass through between the second guide surface 9212a, thereby ensuring the structural compactness of the filter device 9.

[0499] In some embodiments, as Figure 29 As shown, the first guide surface 9211a may include a first guide section 9211b. The first guide section 9211b may be a portion of the first guide surface 9211a located outside the first water inlet 936.

[0500] In some embodiments, the first guide section 9211b is connected to the edge of the second guide section 9211c near the first water inlet 936. At least a portion of the first guide section 9211b is located outside the first water inlet 936 to guide the wash water flowing circumferentially along the wall of the inner drum 1 into the first water inlet 936.

[0501] The first guide section 9211b can guide the washing water flowing circumferentially along the wall of the inner drum 1 into the first water inlet 936, that is, the first guide section 9211b is used to allow more washing water to enter the first water inlet 936 along the first guide section 9211b to increase the water intake of the filter device 9.

[0502] In some embodiments, the second guiding section 9211c is connected to the first guiding section 9211b.

[0503] In this way, the first guide part 9211 can not only guide the washing water entering from the first water inlet 936 to the first filter inlet 951 inside the bracket body 920, but also guide the washing water outside the bracket body 920, so that more washing water enters the bracket body 920.

[0504] In some embodiments, the first guide section 9211b can be constructed as an arc-shaped section so that the first guide section 9211b can abut against the wall of the inner drum 1, so that the first guide section 9211b can introduce more washing water into the first water inlet 936, avoiding the formation of an excessively large gap between the first guide section 9211b and the wall of the inner drum 1. If the gap between the first guide section 9211b and the inner drum 1 is too large, the washing water may flow out of the gap, reducing the diversion effect of the first guide section 9211b.

[0505] In addition, the first guide section 9211b is constructed as an arc-shaped section and abuts against the wall of the inner tube 1. Since the cross-section of the inner tube 1 is usually circular, the wall of the inner tube 1 can have a certain limiting effect on the first guide section 9211b, which can improve the installation stability between the guide bracket 92 and the inner tube 1. In this way, the guide bracket 92 is not easy to shake or swing relative to the wall of the inner tube 1 under the impact of water flow.

[0506] In some embodiments, as Figure 23 and Figure 29As shown, the second flow guiding section 9211c includes a first side edge 9211d and a second side edge 9211e. Both the first side edge 9211d and the second side edge 9211e extend along the axial direction of the inner tube 1.

[0507] The first side edge 9211d and the second side edge 9211e are two opposing edges of the second flow guide section 9211c along the circumference of the inner tube 1. The first side edge 9211d is close to the first water inlet 936 and close to the wall of the inner tube 1. The second side edge 9211e is close to the first filter inlet 951 and closer to the center of the inner tube 1 than the first side edge 9211d.

[0508] In this way, the second guide section 9211 c can guide the washing water flowing along the circumference of the inner drum 1 from the first water inlet 936 to the first filter inlet 951 .

[0509] In some embodiments, as Figure 23 As shown, the second flow guiding section 9211c includes a first curved edge 9211f and a second curved edge 9211g. The second curved edge 9211g is two opposite edges of the second flow guiding section 9211c along the axial direction of the inner cylinder 1.

[0510] In some embodiments, the first curved edge 9211f is an arc line, and the curvature of the first curved edge 9211f is the same as the curvature of the second guide section 9211c.

[0511] In some embodiments, the second curved edge 9211g is an arc line. The curvature of the first curved edge 9211f is the same as that of the second guide segment 9211c.

[0512] In this way, the second guide section 9211c is constructed as a smooth curved surface, so that the washing water forms a Coanda effect after entering the bracket body 920 from the first water inlet 936 and flows along the second guide section 9211c, thereby achieving the purpose of the second guide section 9211c to guide the washing water to the first filter inlet 951.

[0513] In some embodiments, the first guide portion 9211 is configured as a curved plate structure, which can guide water flow more smoothly and reduce resistance and turbulence when the water flows on the first guide portion 9211 .

[0514] In some embodiments, along the extension direction of the first guiding channel 921 , the cross-sectional areas of the first guiding channel 921 are equal.

[0515] The cross-sectional area of ​​the first guide channel 921 remains equal along its extension direction, which can ensure that the washing water maintains a stable flow rate in the process of flowing to the first filter inlet 951, reducing the formation of eddies and turbulence caused by uneven water flow velocity, thereby improving the filtration efficiency of the filter device 9.

[0516] In one embodiment, if Figure 37 As shown, the first outer surface 957 may be a convex arc surface, and the second guide section 9211c may be a concave arc surface.

[0517] The inner wall of the first guide channel 921 formed between the first outer surface 957 and the second guide section 9211c is formed by a smooth curved surface, so that the washing water can flow smoothly along the arc-shaped inner wall of the channel, reducing the resistance of the washing water during the flow, so that the washing water can maintain a uniform speed during the flow, reducing the formation of eddies and turbulence caused by uneven water flow speed, thereby ensuring the guide efficiency of the first guide channel 921.

[0518] In one embodiment, if Figure 37 As shown, the first outer surface 957 can be a convex arc surface. The second guide section 9211c and the first outer surface 957 are parallel to each other.

[0519] This is equivalent to keeping the cross-sectional area of ​​the first guide channel equal along its extension direction, and the washing water maintains a stable flow rate in the process of flowing to the first filter inlet 951, reducing the formation of eddies and turbulence caused by uneven water flow speed, thereby improving the filtration efficiency of the filter device 9.

[0520] In some embodiments, as Figure 37 As shown, the first outer surface 957 is a convex arc surface. The second guide section 9211c is a concave arc surface. The curvature of the second guide section 9211c can be the same as that of the first outer surface.

[0521] The curvature of the first outer surface is the same as that of the second guide section 9211c, so that the washing water can flow smoothly along the curved channel, reducing the resistance of the washing water during the flow, so that the washing water can maintain a uniform speed during the flow, and reducing the formation of eddies and turbulence caused by uneven water flow speed, thereby ensuring the diversion efficiency of the first guide channel 921.

[0522] In some embodiments, as Figure 30 As shown, the first outer surface 957 and the surface of the flow blocking portion 9511 facing the first filter inlet 951 are connected by an arc surface.

[0523] Using an arc surface to connect the first outer surface 957 and the baffle 9511 can achieve a smooth transition from the first outer surface 957 to the baffle 9511, avoiding the fluid resistance that may be caused by right-angle or sharp-angle connections, and helping the washing water maintain a relatively stable flow rate and direction when flowing through the first filter inlet 951, thereby improving the filtration efficiency.

[0524] In some embodiments, as Figure 21 and Figure 26As shown, a wire hanging post 977 may be provided on the box body 970. The wire hanging post 977 is located in the filter cavity 971.

[0525] The hanging post 977 utilizes the fact that impurities such as dander and hair are easily entangled during the washing process. The dander and hair entering the filter chamber 971 during washing can be wrapped around the hanging post 977 to reduce the backflow of hair through the first filter inlet 951.

[0526] At the same time, the hanging post 977 also reduces the filtering burden of the filter 911. The hanging post 977 actually provides a pre-treatment function for the filter 911. When large clumps of dander and hair are entangled on the hanging post 977, the filter 911 can filter smaller particles and prevent large clumps of dander and hair from being blocked on the filter 911, thereby improving the filtering effect of the filter device 9.

[0527] In some embodiments, as Figure 26 and Figure 31 As shown, there are multiple wire hanging posts 977, including multiple first wire hanging posts 9771. The first wire hanging posts 9771 are provided on the first housing 95. The first wire hanging posts 9771 are provided on the surface of the first housing 95 facing the second housing 93. The first wire hanging posts 9771 can extend toward the second housing 93.

[0528] In some embodiments, as Figure 21 As shown, there are multiple wire hanging posts 977, including multiple second wire hanging posts 9772. The second wire hanging posts 9772 are provided on the second housing 93. The second wire hanging posts 9772 are provided on the surface of the second housing 93 facing the first housing 95. The second wire hanging posts 9772 can extend toward the first housing 95.

[0529] In some embodiments, the second housing 93 is movably connected to the first housing 95. When the second housing 93 moves relative to the first housing 95, the filter cavity 971 can be opened or closed, thereby conveniently cleaning hair, hair debris, etc. in the filter box 97.

[0530] In some embodiments, as Figure 21 As shown, the box body 970 may include a hinge structure 941. The hinge structure 941 is provided on the first shell 95 and the second shell 93 so that the first shell 95 and the second shell 93 are rotatably connected.

[0531] The hinge structure 941 may include a rotating shaft arranged on one of the first shell 95 or the second shell 93, and a rotating shaft hole arranged on the other of the first shell 95 or the second shell 93. The rotating shaft can be connected to the rotating shaft hole to realize the rotation of the first shell 95 relative to the second shell 93.

[0532] In some embodiments, as Figure 21 and Figure 26 As shown, a first mounting portion 953 is formed on the first housing 95. The first mounting portion 953 is formed at one end of the first housing 95 away from the hinge structure 941, and the first mounting portion 953 is used for snap-fitting with the second housing 93.

[0533] In some embodiments, as Figure 32 and Figure 35 As shown, a first assembly portion 939 is formed on the second housing 93. The first assembly portion 939 is formed at one end of the second housing 93 away from the hinge structure 941.

[0534] When the second shell 93 rotates toward the first shell 95 through the hinge mechanism to close the filter chamber 971, the first assembly portion 939 can be snap-fitted with the first mounting portion 953 to ensure that the second shell 93 and the first shell 95 remain in a closed state. The closed box body 970 can then be installed to the bracket body 920 to collect hair and dander.

[0535] When the first mounting portion 953 and the first assembly portion 939 are released from engagement, the second housing 93 can rotate relative to the first housing 95 to facilitate cleaning of hair and debris in the filter cavity 971 .

[0536] In some embodiments, the box body 970 and the bracket body 920 are detachably connected.

[0537] In some embodiments, as Figure 32 As shown, a second mounting portion 932 is provided on the top of the second housing 93. The second mounting portion 932 is used for snap-fitting with the bracket body 920.

[0538] In some embodiments, as Figure 24 As shown, a second assembly portion 923 is provided on the top of the bracket body 920. The second assembly portion 923 is used to cooperate with the second mounting portion 932, and the second mounting portion 932 can be pressed into the second assembly portion 923 to connect the top of the second shell 93 to the bracket body 920.

[0539] In some embodiments, the second mounting portion 932 can be configured as a deformable structure. Under the action of an external force, the second mounting portion 932 can elastically deform, allowing the second mounting portion 932 to enter the second assembly portion 923. Once the second mounting portion 932 enters the second assembly portion 923 and the external force disappears, the second mounting portion 932 resumes its elastic deformation, thereby stably engaging with the second assembly portion 923 and achieving a detachable connection between the second mounting portion 932 and the second assembly portion 923.

[0540] In some embodiments, as Figure 25As shown, a third mounting portion 933 is provided at the bottom of the second housing 93. The third mounting portion 933 is used for plugging and mating with the bracket body 920.

[0541] In some embodiments, a third assembly portion is provided on the bracket body 920 , which cooperates with the third mounting portion 933 , and the third mounting portion 933 can be inserted into the third assembly portion to connect the bottom of the second housing 93 to the bracket body 920 .

[0542] During the process of installing the box body 970 to the bracket body 920, the third mounting portion 933 at the bottom of the second shell 93 can be inserted into the third assembly portion at the bottom of the bracket body 920, and then the box body 970 can be rotated so that the second mounting portion 932 at the top of the second shell 93 is inserted into the second assembly portion 923 at the top of the bracket body 920. In this way, the top and bottom of the box body 970 are both limitedly connected to the bracket body 920, and even if the washing water has a large impact force, the box body 970 can be stably set on the bracket body 920.

[0543] When the box body 970 needs to be removed from the bracket body 920, the second mounting portion 932 and the second assembly portion 923 can be disengaged under the action of external force, and then the third mounting portion 933 can be moved out of the third mating portion, so as to conveniently remove the filter box 97 from the bracket body 920, and then continue to clean the dander and hair in the box body 970.

[0544] In some embodiments, as Figure 29 As shown, the second end of the second guide surface 9212a is connected to the second end of the first guide surface 9211a, and an angular portion 9214 is formed at the connection.

[0545] It can be understood that the second end of the second guide surface 9212a, i.e., the second guide surface 9212a, is close to one end of the first filter inlet 951, and the second end of the first guide surface 9211a, i.e., the second guide surface 9212a, is close to one end of the first filter inlet 951. The second end of the second guide surface 9212a is connected to the second end of the first guide surface 9211a, and an angular portion 9214 is formed at the connection. When wash water flows along the first guide surface 9211a, the wash water flows along the first guide surface 9211a to the angular portion 9214 and is unlikely to flow through the angular portion 9214 to the second guide surface 9212a. Instead, the wash water will continue to flow along the guiding direction of the first guide surface 9211a based on the Coanda effect to enter the first filter inlet 951, thereby ensuring that the filtration efficiency of the filter device 9 is improved.

[0546] In some embodiments, the second end of the first guide surface 9211a and the second end of the second guide portion 9212 are both straight edges and extend along the axial direction of the inner cylinder 1 so that the corner portion 9214 extends along the axial direction of the inner cylinder 1 .

[0547] The corner portion 9214 extends along the axial direction of the inner drum 1, so that the corner portion 9214 maintains continuity in the axial direction of the inner drum 1. The continuous corner portion 9214 can effectively reduce the flow deviation that may occur when the washing water flows through the corner portion 9214, further ensuring that the washing water flows efficiently and orderly along the established path.

[0548] In some embodiments, as Figure 30 As shown, the included angle β of the corner portion 9214 satisfies: β>100°.

[0549] The angle β of the corner portion 9214 can be the angle formed by a first tangent passing through the second end of the first guide surface 9211a and tangent to the first guide surface 9211a, and a second tangent passing through the second end of the second guide surface 9212a and tangent to the second guide surface 9212a. β>100° can make the first guide surface 9211a and the second guide surface 9212a relatively flat and continuous curved surfaces, making it easier for washing water to form a Coanda effect on the first guide surface 9211a and the second guide surface 9212a, and also reducing adverse conditions such as water flow dispersion, vortex formation or change of flow direction that may be caused by the small angle between the first guide surface 9211a and the second guide surface 9212a.

[0550] If β is too small, for example: β<100°, it may cause the first guide surface 9211a and the second guide surface 9212a to be too inclined or steep, making it difficult for the washing water flowing through the first guide surface 9211a and the second guide surface 9212a to form a Coanda effect, and the washing water flowing through the first guide surface 9211a and the second guide surface 9212a can easily produce dispersion, vortex or change in flow direction.

[0551] Illustratively, the angle β of the corner portion 9214 may be 101°, 110°, 120°, or 130°.

[0552] In some embodiments, as Figure 30 As shown, the included angle β of the corner portion 9214 satisfies: β<150°.

[0553] The angle β of the corner portion 9214 can be the angle formed by the tangents of the first guide surface 9211a and the second guide surface 9212a. β < 150° can prevent the first guide surface 9211a and the second guide surface 9212a from being too flat, thereby allowing the washing water to flow more quickly along the first guide surface 9211a and the second guide surface 9212a, thereby improving the filtration efficiency of the filter device 9.

[0554] If β is too large, for example, β>150°, the washing water flowing through the first guide surface 9211a may flow out of the filter device 9 from the second water inlet 937, thereby improving the guiding effect of the first guide surface 9211a and the second guide surface 9212a.

[0555] Illustratively, the angle β of the corner portion 9214 may be 130°, 135°, 140°, 145°, or 149°.

[0556] In some embodiments, the angle β of the corner portion 9214 can be any value between 101° and 149°, so as to take into account the guiding effect and guiding efficiency of the first guiding surface 9211a and the second guiding surface 9212a.

[0557] In some embodiments, as Figure 24 As shown, the second end of the first guide surface 9211a and the second end of the second guide surface 9212a are connected to each other. A connection line 9213 is formed at the connection between the first guide surface 9211a and the second guide surface 9212a.

[0558] Since the first air guide portion 9211 and the second air guide portion 9212 extend along the axial direction of the inner tube 1 , the connecting line 9213 between the first air guide portion 9211 and the second air guide portion 9212 also extends along the axial direction of the inner tube 1 .

[0559] It can be understood that the connection between the first guide surface 9211a and the second guide surface 9212a forms a connecting line 9213, which extends axially along the inner drum 1, equivalent to forming a pointed structure at the connection between the first guide surface 9211a and the second guide surface 9212a. When wash water flows along the first guide surface 9211a, it flows along the first guide surface 9211a to the pointed structure. It is unlikely to flow through the pointed structure to the second guide surface 9212a. Instead, it will continue to flow along the guiding direction of the first guide surface 9211a due to the Coanda effect to enter the first filter inlet 951, thereby ensuring improved filtration efficiency of the filter device 9.

[0560] In some embodiments, as Figure 25 and Figure 36 As shown, the filter cavity outlet 931 may include a first filter outlet 9311. The first filter outlet 9311 may be provided through the second housing 93. A filter net 911 is provided in the first filter outlet 9311.

[0561] In some embodiments, the filter cavity outlet 931 may include a second filter outlet 9312. The second filter outlet 9312 may be disposed through the second housing 93, and a filter screen 911 may be provided in the second filter outlet 9312.

[0562] In some embodiments, the second filter outlet 9312 and the first filter outlet 9311 are arranged at intervals along the circumference of the inner tube 1 .

[0563] In some embodiments, along the radial direction of the inner tube 1 , the first filter outlet 9311 and the first guide surface 9211 a are disposed opposite to each other, and the second filter outlet 9312 and the second guide surface 9212 a are disposed opposite to each other.

[0564] That is, the first filter outlet 9311 is located on the side of the first guide surface 9211 a facing the center of the inner tube 1 , and the second filter outlet 9312 is located on the side of the second guide surface 9212 a facing the center of the inner tube 1 .

[0565] In some embodiments, as Figure 29 As shown, the filter device 9 has a centerline oo along the circumference of the inner drum 1. The first filter outlet 9311 and the first flow guide 9211 are located on the same side of the centerline oo, and the second filter outlet 9312 and the second flow guide 9212 are located on the same side of the centerline oo. That is, the first filter outlet 9311 and the first flow guide 9211 are located on one side of the centerline oo, while the second filter outlet 9312 and the second flow guide 9212 are located on the other side of the centerline oo. In some embodiments, the second filter outlet 9312 is located in the flow-guiding direction of the first flow guide surface 9211a.

[0566] The direction of flow directed by the first guide surface 9211a can be understood as the direction in which the first guide surface 9211a extends. This means that the second filter outlet 9312 is located along the path that wash water may take when flowing along the first guide surface 9211a. Wash water enters the bracket body 920 through the first water inlet 936 and flows along the first guide surface 9211a. After entering the first filter inlet 951 along the direction of flow directed by the first guide surface 9211a, the wash water continues its original flow direction and then flows out of the second filter outlet 9312.

[0567] In this way, the washing water can continue to maintain its original flow direction after entering the filter box 97 from the first water inlet 936, and flow out of the filter cavity 971 through the second filter outlet 9312 along the flow direction. The washing water is not easy to form turbulence in the filter cavity 971, so as to improve the hair collection efficiency of the filter device 9.

[0568] It is understood that when wash water is in a turbulent state, the flow direction may be chaotic and the flow rate of the wash water may be uneven, which may cause the wash water to easily flow back and out of the first filter inlet 951, thereby reducing the filtration effect. The second filter outlet 9312, which is offset from the first guide surface 9211a along the circumference of the inner drum 1, can prevent wash water from flowing back during the filtration process and improve the filtration effect.

[0569] In some embodiments, as Figure 36 As shown, the first filter outlet 9311 is located in the guide direction of the second guide surface 9212a. The guide direction of the second guide surface 9212a can be understood as the extension direction of the second guide surface 9212a, that is, the position of the first filter outlet 9311 is on the path that the washing water may pass through when flowing along the second guide surface 9212a.

[0570] Wash water enters the support body 920 through the second water inlet 937 and flows along the second guide surface 9212a. After entering the first filter inlet 951 along the guiding direction of the second guide surface 9212a, the wash water continues to maintain its original flow direction and then flows out from the first filter outlet 9311.

[0571] The first filter outlet 9311, offset from the second guide surface 9212a along the circumference of the inner drum 1, can prevent backflow of wash water during the filtration process, thereby improving the filtration effect. The specific principle is the same as the cooperation between the first guide surface 9211a and the second filter outlet 9312, and will not be repeated here.

[0572] In some implementations, such as Figure 36 As shown, the extended surface of the first flow guide surface 9211 a passes through the second filter outlet 9312 .

[0573] The extension of the first guide surface 9211a refers to a virtual surface extending from the current boundary of the first guide surface 9211a along its flow-guiding direction. The extension of the first guide surface 9211a may be tangent to the second end of the second guide section 9211c. Thus, when the pulsator 2 rotates in the first direction, the first guide surface 9211a is used to direct wash water flowing circumferentially along the wall of the inner drum 1 through the first guide surface 9211a and the first filter inlet 951 into the filter chamber 971, and out of the filter chamber 971 through the second filter outlet 9312.

[0574] During this process, the washing water guided by the first guide surface 9211a can flow out of the filter chamber 971 smoothly along the above-mentioned flow path, and the flow direction of the washing water is not easy to change, thereby reducing the turbulence of the washing water in the filter chamber 971, and further reducing the backflow of the washing water due to the chaotic flow direction, thereby improving the filtering effect of the filter device 9.

[0575] In some implementations, such as Figure 36 As shown, the extended surface of the second flow guide surface 9212 a passes through the first filter outlet 9311 .

[0576] The extended surface of the second flow guiding surface 9212a refers to a virtual surface formed by extending from the current boundary of the second flow guiding surface 9212a along its flow guiding direction. The extended surface of the second flow guiding surface 9212a may be tangent to the second end of the second flow guiding surface 9212a.

[0577] When the impeller 2 rotates in the second direction, the second guide surface 9212a is used to allow the washing water flowing circumferentially along the wall of the inner drum 1 to enter the filter cavity 971 through the second guide surface 9212a and the first filter inlet 951, and flow out of the filter cavity 971 through the first filter outlet 9311.

[0578] During this process, the washing water guided by the second guide surface 9212a can flow out of the filter chamber 971 smoothly along the above-mentioned flow path, and the flow direction of the washing water is not easy to change, thereby reducing the turbulence of the washing water in the filter chamber 971, and further reducing the backflow of the washing water due to the chaotic flow direction, thereby improving the filtering effect of the filter device 9.

[0579] In some embodiments, the first water inlet 936 , the first flow guide 9211 , the first filter inlet 951 , the filter cavity 971 , and the second filter outlet 9312 form a first water flow path.

[0580] When the pulsator 2 rotates in the first direction, the washing water enters the first water inlet 936, is then guided along the first guide portion 9211 to the first filter inlet 951, and enters the filter cavity 971 from the first filter inlet 951. When flowing in the filter cavity 971, the washing water can continue to flow along the original flow direction and flow out from the second filter outlet 9312.

[0581] During this process, the washing water can flow out of the filter chamber 971 smoothly along the first water flow path, and the flow direction of the washing water is not easy to change, thereby reducing the turbulence formed by the washing water before entering the filter chamber 971 and in the filter chamber 971, and thus reducing the backflow of the washing water due to the chaotic flow direction, thereby improving the filtering effect of the filter device 9.

[0582] In some embodiments, the second water inlet 937 , the second guide portion 9212 , the first filter inlet 951 , the filter cavity 971 , and the first filter outlet 9311 form a second water flow path.

[0583] When the pulsator 2 rotates in the second direction, the washing water enters the second water inlet 937, is then guided along the second guide portion 9212 to the first filter inlet 951, and enters the filter cavity 971 from the first filter inlet 951. When flowing in the filter cavity 971, the washing water can continue to flow along the original flow direction and flow out from the first filter outlet 9311.

[0584] During this process, the washing water can flow out of the filter chamber 971 smoothly along the second water flow path, and the flow direction of the washing water is not easy to change, thereby reducing the turbulence formed by the washing water before entering the filter chamber 971 and in the filter chamber 971, and thus reducing the backflow of the washing water due to the chaotic flow direction, thereby improving the filtering effect of the filter device 9.

[0585] In some embodiments, the first water flow path and the second water flow path intersect at the first filter inlet 951 to form a cross water flow path.

[0586] In this manner, the filter device 9 is configured with a first water flow path and a second water flow path. Both the first water flow path and the second water flow path can be used to filter wash water, and the wash water flows out of the filter chamber 971 through the second filter outlet 9312 and the first filter outlet 9311, respectively. This allows the first filter outlet 9311 and the second filter outlet 9312 to filter the wash water evenly. In this way, the pet hair and lint collected by the filter 911 at the first and second filter outlets 9311 and 9312 are relatively evenly distributed, preventing excessive concentration of hair and lint from clogging the filter 911 in a local area. This allows both the first filter outlet 9311 and the second filter outlet 9312 to perform their filtering functions. Furthermore, the intersecting arrangement of the first and second water flow paths allows the two water flow paths to share the same first filter inlet 951, thereby making the structure of the bracket body 920 more compact and stronger.

[0587] In some embodiments, as Figure 23 As shown, the guide bracket 92 may include a through-port 9204. The through-port 9204 is formed at the bottom of the bracket body 920, that is, the through-port 9204 is arranged toward the pulsator 2, and the through-port 9204 is connected to the washing chamber 11.

[0588] In some embodiments, as Figure 35 As shown, the filter box 97 may include a second filter inlet 952. The second filter inlet 952 is another water inlet of the filter box 97. The second filter inlet 952 is formed on the bottom surface of the box body 970. That is, the second filter inlet 952 is arranged toward the impeller 2.

[0589] In some embodiments, the second filter inlet 952 is connected to the through-port 9204 , that is, the second filter inlet 952 is connected to the washing chamber 11 through the through-port 9204 .

[0590] The through opening 9204 on the bracket body 920 is configured to allow the washing water flowing upward along the wall of the inner drum 1 to enter the second filter inlet 952 through the through opening 9204 when the pulsator 2 rotates.

[0591] In some embodiments, the second filter inlet 952 faces the pulsator 2 , that is, the second filter inlet 952 connects the washing chamber 11 and the filter chamber 971 along the axial direction of the inner drum 1 .

[0592] In this way, when the pulsator 2 rotates, the washing water flowing upward along the wall of the inner drum 1 can pass through the through port 9204 and the second filter inlet 952 and enter the filter cavity 971.

[0593] The first filter inlet 951 is for the washing water guided from the first guide part 9211 and the second guide part 9212 to enter. The washing water enters the bracket body 920 through the first water inlet 936 and the second water inlet 937. That is, the hair and hair debris that easily float on the upper layer of the washing water can more easily enter the first filter inlet 951 from the first water inlet 936 and the second water inlet 937 on the side of the filter device 9, and then be filtered through the filter cavity 971.

[0594] Different from the first filter inlet 951, the second filter inlet 952 is used to filter the hair and lint that are more likely to sink to the bottom of the washing chamber 11 in the washing water, or the hair that is disturbed to the bottom of the washing chamber 11 by the washing water. These hair and lint that are larger in mass and easier to sink enter the second filter inlet 952 of the filter box 97 through the opening 9204 when the washing water surges upward, and are filtered by the filter mesh 911 and collected in the filter chamber 971.

[0595] In this way, the filter device 9 provided in the embodiment of the present application can not only filter out light impurities such as hair and dander that easily float on the upper layer of the washing water through the first water inlet 936, the second water inlet 937 and the first filter inlet 951, but can also filter out general dander that is relatively heavy and easily sinks to the bottom of the washing chamber 11 through the through port 9204 and the second filter inlet 952, so that the filter device 9 has a more comprehensive filtering capability.

[0596] In some embodiments, as Figure 26 、 Figure 31 and Figure 34 As shown, the box body 970 may include a first barrier 954. The first barrier 954 is disposed in the filter cavity 971, one end of the first barrier 954 is disposed in one of the first shell 95 or the second shell 93, and the other end of the first barrier 954 abuts against the other of the first shell 95 or the second shell 93.

[0597] In this way, the first barrier 954 can separate the filter cavity 971 into two independent first filter cavity 9711 and second filter cavity 9712 .

[0598] In some embodiments, as Figure 35As shown, the first filter cavity 9711 and the second filter cavity 9712 are arranged along the axial direction of the inner tube 1.

[0599] In some embodiments, the first filter cavity 9711 is in communication with the first filter inlet 951 , and the second filter cavity 9712 is in communication with the second filter inlet 952 .

[0600] In this way, the washing water entering from the first water inlet 936 and the second water inlet 937 from the circumference of the inner drum 1 and guided to the first filter inlet 951 by the first guide part 9211 and the second guide part 9212 can be isolated from the washing water entering the second filter inlet 952 from the bottom of the washing chamber 11 to avoid the confluence of two washing water flows in different directions and the generation of turbulence in the filter chamber 971.

[0601] In some embodiments, as Figure 26 As shown, the first filter cavity 9711 is opposite to the first flow guide portion 9211 and the second flow guide portion 9212 along the radial direction of the inner cylinder 1 .

[0602] The first filter chamber 9711 is arranged opposite to the first guide portion 9211 and the second guide portion 9212 along the radial direction of the inner cylinder 1, which can ensure that the washing water guided by the first guide portion 9211 and the second guide portion 9212 can enter the first filter chamber 9711 as much as possible, and can also ensure that the first filter chamber 9711 does not occupy too much space of the second filter chamber 9712, so as to optimize the spatial relationship between the first filter chamber 9711 and the second filter chamber 9712.

[0603] In some embodiments, the length of the first filter cavity 9711 along the axial direction of the inner cylinder 1 is adapted to the length of the first flow guide portion 9211 along the axial direction of the inner cylinder 1 .

[0604] In this way, it can be ensured that the washing water guided by the first guide part 9211 can enter the first filter chamber 9711 as much as possible, and it can also be ensured that the first filter chamber 9711 does not occupy too much space of the second filter chamber 9712, so as to optimize the spatial relationship between the first filter chamber 9711 and the second filter chamber 9712.

[0605] In some embodiments, as Figure 33 and Figure 34 As shown, along the axial direction of the inner tube 1 , the first filter cavity 9711 has an eighth preset height H8, and the second filter cavity 9712 has a ninth preset height H9, and H8 and H9 satisfy: H8 / H9>2.

[0606] The first filter chamber 9711 is used to collect hair located in the upper layer of the wash water. The filtration space of the first filter chamber 9711 should be ensured to have a sufficient preset height. The second filter chamber 9712 is used to collect lint near the bottom of the wash chamber 11. This ensures that the filtration efficiency of the second filter chamber 9712 is not affected even at lower water levels. Therefore, the second filter chamber 9712 can occupy less space than the first filter chamber 9711 to ensure that the first filter chamber 9711 can collect as much hair as possible at all water levels. Therefore, if H8 / H9>2, the collection efficiency of the first filter chamber 9711 can be guaranteed. If H8 / H is too small, for example, H8 / H<2, the collection efficiency of the first filter chamber 9711 may be affected, resulting in the first filter chamber 9711 being unable to effectively collect hair at higher or lower water levels.

[0607] Specifically, the ratio of the eighth preset height H8 to the ninth preset height H9 may be 2.1, 2.3, 2.5, 3 or 3.5.

[0608] In some embodiments, as Figure 33 and Figure 34 As shown, along the axial direction of the inner tube 1 , the first filter cavity 9711 has an eighth preset height H8, and the second filter cavity 9712 has a ninth preset height H9, and H8 and H9 satisfy: H8 / H9<5.

[0609] Since the first filter chamber 9711 is primarily used to collect hair from the upper layer of the wash water, and the water level range of the pulsator washing machine 100 is relatively wide, the first filter chamber 9711 is longer, allowing it to adapt to a wider water level range and thereby collecting more hair. However, it is also necessary to ensure that the second filter chamber 9712 has a sufficient amount of filtration space. Therefore, H8 / H9<5 ensures that the first filter chamber 9711 does not occupy too much of the filtration space of the second filter chamber 9712.

[0610] It can be understood that if H8 / H9 is too large, for example, H8 / H9>5, and the total volume of the filter chamber 971 is fixed, the first filter chamber 9711 may occupy too much of the filtering space of the second filter chamber 9712, affecting the second filter chamber 9712's collection effect on heavier impurities, lint and hair that is carried to the bottom of the washing chamber 11 by the washing water.

[0611] Specifically, the ratio of the eighth preset height H8 to the ninth preset height H9 may be 3.5, 4, 4.5 or 4.9.

[0612] In some embodiments, the ratio of the eighth preset height H8 to the ninth preset height H9 may be any value between 2.1 and 4.9, so as to take into account the lint collection effects of the first filter cavity 9711 and the second filter cavity 9712 .

[0613] In some embodiments, as Figure 31 As shown, the first hanging post 9771 is located in the first filter cavity 9711. This ensures that large clumps of hair, wire scraps, etc. entering the first filter cavity 9711 can be wound around the first hanging post 9771, while preventing the large clumps of hair from clogging the filter screen 911 of the first filter cavity 9711.

[0614] In some embodiments, as Figure 21 As shown, the second hanging post 9772 is located in the second filter cavity 9712. This ensures that large balls of hair, wire scraps, etc. entering the second filter cavity 9712 can be wound around the second hanging post 9772, while preventing the large balls of hair from clogging the filter screen 911 of the second filter cavity 9712.

[0615] In some embodiments, as Figure 26 and Figure 31 As shown, the box body 970 may include at least one second barrier 955. One end of the second barrier 955 is disposed in one of the first shell 95 or the second shell 93, and the other end of the second barrier 955 abuts against the other of the first shell 95 or the second shell 93.

[0616] In some embodiments, the second barrier 955 can separate the filter cavity 971 into a plurality of sub-filter cavities 9711 a . The plurality of sub-filter cavities 9711 a are arranged along the axial direction of the inner cylinder 1 .

[0617] In some embodiments, the first filter inlet 951 is communicated with the plurality of sub-filter cavities 9711 a respectively, and the filter cavity outlet 931 is communicated with the plurality of sub-filter cavities 9711 a respectively.

[0618] Wash water flowing into the first filter inlet 951 at different water levels can enter multiple sub-filter chambers 9711a. Hair and lint floating in the wash water can enter different sub-filter chambers 9711a. Each sub-filter chamber 9711a is equipped with a connected filter chamber outlet 931 to improve the filtering effect.

[0619] In this way, hair and lint can be relatively evenly distributed in multiple sub-filter chambers 9711a or deposited on each second barrier member 955 to avoid excessive concentration of hair and lint at the bottom of the filter chamber 971 and clogging it, causing the filter net 911 at the bottom of the filter chamber 971 to be blocked, thereby affecting the filtering effect of the filter device 9.

[0620] In some embodiments, the length of the first filter inlet 951 along the axial direction of the inner cylinder 1 is adapted to the sum of the lengths of the plurality of sub-filter cavities 9711 a along the axial direction of the inner cylinder 1 .

[0621] The axial length of the first filter inlet 951 along the inner cylinder 1 is compatible with the sum of the axial lengths of the multiple sub-filter cavities 9711a along the inner cylinder 1. This can be understood as the first filter inlet 951 corresponding to each sub-filter cavity 9711a along the axial direction of the inner cylinder 1, or the axial length of the first filter inlet 951 along the inner cylinder 1 is equal to or nearly equal to the sum of the axial lengths of the multiple sub-filter cavities 9711a along the axial direction of the inner cylinder 1. This ensures that the first filter inlet 951 is connected to each sub-filter cavity 9711a along the axial direction of the inner cylinder 1. As long as the wash water entering through the first filter inlet 951 can enter a sub-filter cavity 9711a for filtration, each sub-filter cavity 9711a operates independently and can simultaneously filter wash water from different water levels, thereby ensuring the overall filtration efficiency of the filter device 9.

[0622] In some embodiments, the length of the first filter inlet along the axial direction of the inner cylinder is H11, the sum of the lengths of the plurality of sub-filter cavities along the axial direction of the inner cylinder is H12, and H11 / H12 satisfies: H11 / H12>0.9.

[0623] H11 / H12>0.9, which can ensure that the washing water entering from the first filter inlet 951 can enter the multiple sub-filter chambers 9711a as much as possible, so as to improve the independent filtering performance of each sub-filter chamber 9711a, and make the hair and lint entering the first filter inlet 951 with the washing water enter the multiple sub-filter chambers 9711a evenly, so as to avoid the hair and lint from being concentrated and deposited at the bottom of the filter chamber 971.

[0624] If H11 / H12 is too small, such as H11 / H12<0.9, the total length of the multiple sub-filter cavities 9711a may be too long to correspond to the first filter inlet 951. The multiple sub-filter cavities 9711a may cause space waste and reduce the structural compactness of the filter device 9.

[0625] Illustratively, H11 / H12 may be 0.91, 0.92, 0.95 or 1.

[0626] In some embodiments, the length of the first filter inlet along the axial direction of the inner cylinder is H11, the sum of the lengths of the plurality of sub-filter cavities along the axial direction of the inner cylinder is H12, and H11 / H12 satisfies: or H11 / H12<1.1.

[0627] H11 / H12<1.1, which can ensure that the washing water entering from the first filter inlet 951 can enter the multiple sub-filter chambers 9711a as much as possible, so that each sub-filter chamber 9711a corresponds to the first filter inlet 951 as much as possible. In this way, the washing water entering from the first filter inlet 951 can flow into the multiple sub-filter chambers 9711a as much as possible to ensure the filtering effect of the filter device 9.

[0628] If H11 / H12 is too large, such as H11 / H12>0.9, the first filter inlet 951 may be too long, and the wash water entering from the first filter inlet 951 may not all enter the multiple sub-filter chambers 9711a, thereby reducing the filtering effect of the filter device 9. For example, H11 / H12 can be 1, 1.05, or 1.09.

[0629] In some embodiments, H11 / H12 may be any value between 0.91 and 1.09.

[0630] In some embodiments, the upper surface of the second barrier 955 is flat.

[0631] As a result, the second barrier 955 can better receive the hair, and the hair and lint are more easily deposited on the second barrier 955 under the action of gravity, so as to prevent the hair and lint from being blocked on the filter 911, thereby ensuring the filtering effect of the filter 911.

[0632] In some embodiments, as Figure 35 As shown, the second barrier 955 divides the first filter cavity 9711 into a plurality of sub-filter cavities 9711 a. The plurality of sub-filter cavities 9711 a are arranged along the axial direction of the inner cylinder 1.

[0633] In this way, the hair and lint collected in the first filter chamber 9711 are not easy to accumulate at the bottom of the first filter chamber 9711, and can be relatively evenly distributed in multiple sub-filter chambers 9711a or deposited on each second partition member 955 to avoid excessive hair and lint causing blockage of the bottom of the first filter chamber 9711 and affecting the filtering effect of the filter device 9.

[0634] In some embodiments, the number of the second blocking members 955 may be two, three, or four, which may be determined based on the axial length of the first filter cavity 9711 along the inner cylinder 1 .

[0635] In some embodiments, along the axial direction of the inner tube 1 , the lengths of the sub-filter cavities 9711 a are equal.

[0636] The lengths of the sub-filter cavities 9711a are equal, which can ensure that each sub-filter cavity 9711a can collect hair and lint relatively evenly, and reduce the situation where hair and lint are concentrated in a certain sub-filter cavity 9711a.

[0637] In some embodiments, along the axial direction of the inner tube 1 , the length of each sub-filter cavity 9711 a decreases layer by layer from top to bottom.

[0638] When washing a smaller number of knitted fabrics, the water level in the washing machine may be reduced accordingly, so the sub-filter chambers 9711a located near the bottom of the inner drum 1 are more frequently used. The decreasing length of the sub-filter chambers 9711a from top to bottom allows the more frequently used portions of the filter chamber 971 to be divided into more sub-filter chambers 9711a, thereby reducing clogging of the filter screens 911 corresponding to the frequently used sub-filter chambers 9711a. Hair and lint can be retained on the gradually increasing number of second baffles 955.

[0639] In some embodiments, the support body 920 may include a first support side wall 9201. The first water inlet 936 is disposed on the first support side wall 9201. The first support side wall 9201 may extend along the axial direction of the inner tube 1.

[0640] In some embodiments, as Figures 22 to 24 As shown, a plurality of first support ribs 9207 are provided on the bracket body 920. The plurality of first support ribs 9207 are connected to the first bracket side wall 9201 and the first guide portion 9211 and are located at the first water inlet 936 to provide structural support for the first bracket side wall 9201.

[0641] In some embodiments, the bracket body 920 may include a second bracket sidewall 9202. The second bracket sidewall 9202 may extend along the axial direction of the inner tube 1. The second bracket sidewall 9202 and the first bracket sidewall 9201 are arranged opposite to each other along the circumference of the inner tube 1, and the second water inlet 937 is provided on the second bracket sidewall 9202.

[0642] In some embodiments, the support body 920 is provided with a plurality of second support ribs 9208. The plurality of second support ribs 9208 are connected to the second support sidewall 9202 and the second guide portion 9212 and are located at the second water inlet 937 to provide structural support for the second support sidewall 9202.

[0643] In some embodiments, the bracket body 920 may include a third bracket sidewall 9203 . The third bracket sidewall 9203 is connected between the bottom end of the first bracket sidewall 9201 and the bottom end of the second bracket sidewall 9202 . A through opening 9204 may be formed in the third bracket sidewall 9203 .

[0644] In some embodiments, the third assembly portion can be a portion of the through opening 9204. When the box body 970 is installed in the installation cavity 8209, the first plug portion can be inserted into the through opening 9204, and the third installation portion 933 abuts against the wall of the second box body 970, thereby limiting the position of the box body 970 and the bracket body 920.

[0645] In some embodiments, the bracket body 920 may include a fourth bracket sidewall 9205 . The fourth bracket sidewall 9205 is connected between the top end of the first bracket sidewall 9201 and the top end of the second bracket sidewall 9202 . The second assembly portion 923 may be formed on the fourth bracket sidewall 9205 .

[0646] The first bracket side wall 9201 , the second bracket side wall 9202 , the third bracket side wall 9203 and the fourth bracket side wall 9205 can enclose an installation cavity 8209 , and the filter box 97 can be detachably connected to the installation cavity 8209 .

[0647] In this way, on the basis that the filter box 97 is connected to the bracket body 920 through the second mounting part 932 and the third mounting part 933, the filter box 97 is placed in the space enclosed by the first bracket side wall 9201, the second bracket side wall 9202, the third bracket side wall 9203 and the fourth bracket side wall 9205, which can further improve the installation stability of the filter box 97.

[0648] In some embodiments, the first guide portion 9211 and the second guide portion 9212 are disposed in the installation cavity 8209. The first guide portion 9211 and the second guide portion 9212 are located in the upper space of the installation cavity 8209 to correspond to the first filter cavity 9711 located above the installation cavity 8209.

[0649] In some embodiments, as Figure 24 As shown, the bracket body 920 may include a back plate 9206. The back plate 9206 is connected to the mounting cavity 8209 and is located below the first guide portion 9211 and the second guide portion 9212.

[0650] In some embodiments, the back plate 9206 and the second filter cavity 9712 are opposite to each other along the radial direction of the inner tube 1 , and the box wall of the filter box 97 corresponding to the second filter cavity 9712 is in contact with the back plate 9206 .

[0651] The back plate 9206 corresponds to the box wall forming the second filter cavity 9712. The portion of the second housing 93 forming the second filter cavity 9712 protrudes toward the support body 920 and abuts against the back plate 9206. The back plate 9206 provides support for the portion of the second housing 93 forming the second filter cavity 9712, thereby further ensuring the support stability of the support body 920 for the filter box 97.

[0652] In some embodiments, as Figure 24 As shown, the back plate 9206 is connected to the first bracket side wall 9201 and the second bracket side wall 9202. The back plate 9206 is located between the first bracket side wall 9201 and the second bracket side wall 9202.

[0653] In some embodiments, the first bracket sidewall 9201 is connected to the first air guide portion 9211 , and the second bracket sidewall 9202 is connected to the second air guide portion 9212 .

[0654] In this way, the back plate 9206 can provide certain structural support to the first air guide portion 9211 , the second air guide portion 9212 , and the first bracket side wall 9201 and the second bracket side wall 9202 .

[0655] In some embodiments, the back plate 9206 includes a curved surface 9206a. The curvature of the curved surface 9206a may be the same as or close to the same as the curvature of the wall of the inner cylinder 1.

[0656] In some embodiments, the curved surface 9206a of the back plate 9206 abuts against the wall of the inner drum 1. Thus, when the back plate 9206 abuts against the wall of the inner drum 1, the curved surface 9206a can fit the inner drum 1, reducing the gap between the back plate 9206 and the wall of the inner drum 1, and reducing the flow of wash water through the gap between the back plate 9206 and the wall of the inner drum 1. This, on the one hand, can improve the water flow guidance efficiency of the flow guide bracket 92, allowing wash water to enter the flow guide bracket 92 from the first water inlet 936, the second water inlet 937, or the through-port 9204. On the other hand, the wall of the inner drum 1 provides structural support for the back plate 9206, thereby improving the installation stability and compactness of the filter device 9 and the wall of the inner drum 1, and alleviating the impact force of wash water on the filter device 9.

[0657] In addition, the back plate 9206 abutting against the wall of the inner tube 1 further strengthens the support strength of the back plate 9206 to the first guide part 9211, the second guide part 9212, and the first bracket side wall 9201 and the second bracket side wall 9202, thereby improving the overall structural strength of the filter device 9.

[0658] In some embodiments, as Figure 31 and Figure 34 As shown, the box body 970 may include a water stopper 940. One end of the water stopper 940 may be clamped on the box body 970. The water stopper 940 is located at the second filter inlet 952 to facilitate opening or closing the second filter inlet 952.

[0659] In some embodiments, the water retaining member 940 is an elastic water retaining member 940. The water retaining member 940 can be made of a silicone or rubber material that is highly elastic, wear-resistant, and corrosion-resistant.

[0660] Since the second filter inlet 952 is located at the bottom of the filter box 97, the wash water surges upward to impact the water retaining member 940. Since one end of the water retaining member 940 is clamped on the box body 970, there is no other structure to support the water retaining member 940 on the side of the elastic water retaining member 940 facing the second filter cavity 9712. Therefore, the elastic water retaining member 940 will be deformed under the impact of the upward flow of wash water. The deformed water retaining member 940 is able to open the second filter inlet 952 to allow wash water to enter the second filter cavity 9712 from the second filter inlet 952.

[0661] In some embodiments, as Figure 26 and Figure 31 As shown, the box body 970 may include a limiting member 956. The limiting member 956 is used to limit and structurally support the water retaining member 940. The limiting member 956 is located on a side of the water retaining member 940 away from the filter cavity 971.

[0662] Since the filter box 97 is provided with a filter chamber outlet 931, the filter chamber outlet 931 is connected to the washing chamber 11. When the washing water flows in the washing chamber 11, it is possible that some of the washing water will flow into the washing chamber 11 from the filter chamber outlet 931. At this time, the washing water flowing in from the filter chamber outlet 931 will impact the water retaining member 940. However, since the water retaining member 940 is provided with a limiting member 956 on the side away from the filter chamber 971, the limiting member 956 forms a structural support for the water retaining member 940. Therefore, the water retaining member 940 will not produce elastic deformation, that is, the water retaining member 940 will not open the second filter inlet 952, so as to achieve the purpose of the water retaining member 940 preventing the washing water from flowing back.

[0663] It can be understood that even if some washing water flows into the washing chamber 11 from the filter chamber outlet 931, this washing water will not flush the water retaining member 940. Instead, the impact force of the water flow can press the water retaining member 940 tightly against the limiting member 956, so that the water retaining member 940 remains in a state of closing the second filter inlet 952, thereby further strengthening the purpose of preventing the backflow of washing water in the filter chamber 971.

[0664] In some embodiments, as Figure 26 As shown, the limiting member 956 may include a stop surface 9561. The stop surface 9561 is used to cooperate with the water stop member 940 in a limiting manner. The stop surface 9561 is arranged to be inclined relative to the axial direction of the inner tube 1.

[0665] The inclined stop surface allows the water retaining member 940 to be inclined when closing the second filter inlet 952. In this way, the inclined water retaining member 940 is more easily flushed away by the washing water surging and flowing upward from below to open the second filter inlet 952, thereby improving the filtering efficiency of the washing device.

[0666] In some embodiments, the connection end between the water stopper 940 and the box body 970 is lower than the free end of the water stopper 940 .

[0667] In this way, the cooperation between the water retaining member 940 and the limiting member 956 not only ensures that the upwardly rolling washing water can smoothly pass through the second filter inlet 952 and enter the second filter chamber 9712 for filtering, but also closes tightly under the impact of the washing water in the washing chamber 11, effectively preventing the leakage of hair and lint and the backflow of washing water.

[0668] In some embodiments, as Figure 30 As shown, the included angle between the first bracket side wall 9201 and the wall of the inner tube 1 is α, and α satisfies: α<90°.

[0669] It should be noted that the angle between the first bracket side wall 9201 and the wall of the inner tube 1 can be the angle between the first bracket side wall 9201 and the first tangent of the wall of the inner tube 1, and the first tangent passes through the intersection between the first bracket side wall 9201 and the wall of the inner tube 1.

[0670] The first water inlet 936 is formed on the first bracket side wall 9201 . If the angle between the first bracket side wall 9201 and the wall of the inner tube 1 is too large, the first bracket side wall 9201 may be too tilted, thereby affecting the water inlet area of ​​the first water inlet 936 .

[0671] Specifically, the angle α may be 80°, 82°, 84°, 86°, 88° or 89°.

[0672] In some embodiments, as Figure 30 As shown, the included angle between the first bracket side wall 9201 and the wall of the inner tube 1 is α, and α satisfies: α>70°.

[0673] The first water inlet 936 is formed on the first bracket side wall 9201. If the angle between the first bracket side wall 9201 and the wall of the inner tube 1 is too small, the first bracket side wall 9201 may be too tilted, thereby affecting the water inlet area of ​​the first water inlet 936.

[0674] Specifically, the angle α may be 71°, 72°, 74°, 76°, 78° or 80°.

[0675] In some embodiments, the angle α between the first bracket side wall 9201 and the wall of the inner cylinder 1 can be any angle between 71° and 89° to ensure that the first water inlet 936 has a suitable water inlet area, thereby ensuring the filtration efficiency of the filtration device 9.

[0676] In some embodiments, the first water inlet 936 extends along the axial direction of the inner tube 1 .

[0677] The first water inlet 936 extends axially along the inner drum 1, which increases the water inlet area of ​​the first water inlet 936, allowing more wash water to enter the first water inlet 936 as it flows circumferentially along the inner drum 1. The second water inlet 937 has the same structure as the first water inlet 936 and will not be described in detail here.

[0678] In some embodiments, as Figure 26 and Figure 24 As shown, the pulsator washing machine 100 may include a scrubbing member 96. The scrubbing member 96 is provided on a side of the box body 970 facing the washing chamber 11.

[0679] The scrubbing member 96 can contact the textiles in the washing chamber 11, thereby scraping the hair and hair debris on the textiles and dropping them into the washing water, so that the hair attached to the textiles is effectively dispersed in the washing water as much as possible and enters the filter device 9 with the washing water, so that as much hair as possible is collected in the filter device 9.

[0680] In some embodiments, the cleaning member 96 may be made of a flexible material to reduce the risk of the cleaning member 96 being too hard and damaging the textiles.

[0681] Specifically, the scrubbing member 96 can be made of a flexible material such as rubber. When clothes with lint come into contact with the scrubbing member, the scrubbing member 96 is flexible and the clothes contacting its surface will generate a large friction force to scrape the lint attached to the clothes into the washing water. This achieves the effect of scraping the lint on the clothes into the washing water without damaging the clothes.

[0682] Specifically, the cleaning member 96 can be made of flexible materials such as rubber and silicone to reduce damage to the fibers on the surface of the textile. This ensures that the cleaning member 96 has sufficient strength to scrape the hair off the knitted fabric, while also taking into account the flexible treatment of the knitted fabric to ensure that the surface of the knitted fabric is intact.

[0683] In some embodiments, the connection between the scrubbing member 96 and the box body 970 can be a plug-in or snap-in connection.

[0684] In some embodiments, along the circumference of the inner drum 1 , the scrubbing member 96 is located between the first filter outlet 9311 and the second filter outlet 9312 .

[0685] Because hair tends to get tangled, hair scrubbed from textiles by the washing member 96 may become entangled in the washing member 96. Wash water flowing in through the first water inlet 936 is directed by the first guide 9211 and then flows out of the second filtered outlet 9312. Wash water flowing in through the second water inlet 937 is directed by the second guide 9212 and then flows out of the first filtered outlet 9311. Positioning the washing member 96 between the first filtered outlet 9311 and the second filtered outlet 9312 prevents hair entangled in the washing member 96 from being washed away by the wash water flowing out of the filter cartridge 97. After washing, the user can remove the hair caught on the washing member 96.

[0686] In some embodiments, the second housing 93 may include a plurality of mounting holes 934. The plurality of mounting holes 934 are spaced apart along the axial direction of the inner cylinder 1. Each of the plurality of mounting holes 934 is located between the first filter outlet 9311 and the second filter outlet 9312.

[0687] In some embodiments, the scrubbing member 96 may include a connecting portion 961 , which is disposed in the box body 970 and abuts against the second shell 93 .

[0688] In some embodiments, as Figure 21 As shown, a receiving portion 938 may be formed on one side of the second housing 93 facing the first housing 95 . The connecting portion 961 may be locked in the receiving portion 938 .

[0689] In some embodiments, the scrubbing member 96 may include a plurality of scrubbing heads 962. The plurality of scrubbing heads 962 are disposed on a connecting portion 961. The plurality of scrubbing heads 962 and the connecting portion 961 are an integrated structure to ensure the structural strength of the scrubbing member 96.

[0690] There are multiple brush heads 962, which can further improve the efficiency of brushing hair off textiles.

[0691] In some embodiments, one end of each scrubbing head 962 is connected to the connecting portion 961 , and the other end of the scrubbing head 962 passes through the mounting hole 934 and extends into the washing chamber 11 , and the scrubbing head 962 is snap-connected to the mounting hole 934 .

[0692] When the scrubbing member 96 needs to be installed on the box body 970, the connecting portion 961 can be clamped on the second shell 93, and the scrubbing head 962 can be aligned with the mounting hole 934 and the connecting portion 961 can be pressed down. The scrubbing head 962 passes through the mounting hole 934 and is clamped in the mounting hole 934, so that the scrubbing member 96 can be stably set on the second shell 93, and the installation efficiency of the scrubbing member 96 is also improved.

[0693] In some embodiments, there may be multiple first filter outlets 9311 , which are arranged along the axial direction of the inner drum 1 . The multiple first filter outlets 9311 can allow the filtered washing water to quickly flow out of the filter box 97 .

[0694] In some embodiments, there may be multiple second filter outlets 9312 , which are arranged along the axial direction of the inner drum 1 . The multiple second filter outlets 9312 can allow the filtered washing water to quickly flow out of the filter box 97 .

[0695] In some embodiments, a plurality of scrubbing heads 962 may be arranged along the axial direction of the inner tube 1 . In the radial direction of the inner tube 1 , each scrubbing head 962 is located between a first filter outlet 9311 and a second filter outlet 9312 .

[0696] In this way, the hair hanging on the scrubbing head 962 can be prevented from being washed away by the washing water flowing out of the first filter outlet 9311 and the second filter outlet 9312, so that the user can clean the hair after washing.

[0697] In some implementations, such as Figure 18 As shown, the washing member 96 has a tenth preset height H10 along the axial direction of the inner cylinder 1 , and the filter box 97 has a seventh preset height H7 along the axial direction of the inner cylinder 1 , and H10 / H7>0.2.

[0698] The washing member 96 has a tenth preset height along the axial direction of the inner drum 1. The washing member 96 has a certain length to ensure the scraping effect on the knitted fabric, so that the knitted fabric at various water levels in the washing chamber 11 is in contact with the washing member 96 as much as possible, so as to improve the efficiency of rubbing hair off the knitted fabric.

[0699] If H10 / H7 is too small, the scrubbing member 96 may not be able to fully scrape the knitted fabrics at all water levels, or may not be able to contact the knitted fabrics at higher or lower water levels, thereby affecting the scraping effect of the scrubbing member 96.

[0700] Illustratively, H10 / H7 may be 0.21, 0.3, 0.4 or 0.5.

[0701] In some implementations, the scrubbing member 96 has a tenth preset height H10 along the axial direction of the inner tub 1 , and the filter box 97 has a seventh preset height H7 along the axial direction of the inner tub 1 , where H10 / H7<0.9.

[0702] The filter box 97 provides a foundation for the installation of the scrubbing member 96. When H10 / H7 is less than 0.9, a certain distance between the scrubbing member 96 and both ends of the filter box 97 along the axial direction is maintained to ensure the structural strength of the filter box 97 and the stability of the scrubbing member 96 installed on the filter box 97. If H10 / H7 is too large, the filter box 97 may have too many mounting holes 934, thereby reducing the structural strength of the filter box 97.

[0703] Illustratively, H10 / H7 may be 0.6, 0.7, 0.8 or 0.89.

[0704] In some embodiments, H10 / H7 may be any value between 0.21 and 0.89, so as to take into account both the installation stability of the washing member 96 and the scraping effect of the washing member 96 .

[0705] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
