[0048] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "the" and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "Plural" generally includes at least two, but does not exclude the case of including at least one.

[0050] It should be understood that the term "and / or" used herein is only a description of the associated relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0051] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the said element.

[0052] Currently, there are mainly pulsator washing machines, drum washing machines and agitator washing machines. Although these washing machines have a certain washing effect, when washing close-fitting clothes such as underwear and panties, due to the lack of clothing shaping parts, the clothes are in a stacked state, reducing the contact area between the clothes and the washing water, lowering the washing efficiency, and at the same time causing deformation and surface wear of the clothes, shortening the lifespan of the clothes; in addition, the structure of the washing parts is single and cannot adapt to different types of close-fitting clothes, resulting in a narrow washing range;

[0053] The present invention provides a washing assembly disposed in a washing tub. The washing assembly includes a plug board and a kneading and washing structure. The kneading and washing structure includes an intermediate frame and a profiling frame. The intermediate frame is movably disposed on the plug board. The profiling frame is formed with a profiling structure adapted to a preset washing object. The profiling structure includes at least two. At least two profiling structures are oppositely disposed on the intermediate frame and the two profiling frames can rotate relative to the plug board along with the intermediate frame. When washing the preset washing object, the preset washing object is sleeved on the outer side surface of the profiling structure. The profiling structure can support the preset washing object. The preset washing object and the profiling structure rotate along with the intermediate frame under the action of the water flow in the washing tub. Thus, the water in the washing tub can wash the preset washing object.

[0054] The intermediate frame can be adapted to various types of profiling frames. Different types of profiling frames can be set on the intermediate frame according to different preset washing objects. The intermediate frame is disposed on the plug board. The plug board is detachably disposed in the washing tub, expanding the washing range of the kneading and washing structure and improving the washing effect. The profiling structure supports the preset washing object, enabling the preset washing object to maintain its original shape during the washing process, expanding the contact area between the washing water and the preset washing object, and increasing the friction force between the washing water and the preset washing object.

[0055] As Figure 2a and Figure 2b shown, this embodiment provides a washing assembly disposed in a washing tub, including a plug board 51 and a kneading and washing structure. The kneading and washing structure includes:

[0056] An intermediate frame 553 movably disposed on the plug board 51;

[0057] A profiling frame 551 formed with a profiling structure adapted to a preset washing object for supporting and washing the preset washing object. The profiling structure includes at least two. At least two profiling structures are oppositely disposed on the intermediate frame and the two profiling frames 551 can rotate relative to the plug board 51 along with the intermediate frame 553. Preferably, the preset washing object is a bra, and the profiling frame 551 is formed with two cup structures imitating the bra.

[0058] <Connection between the plug board and the profiling frame>

[0059] As Figure 4a 、 Figure 4b 、 Figure 4c 、 Figure 5a 、 Figure 5b and Figure 5c shown, the corresponding profiling frame 551 can be disposed on the plug board 51 according to actual needs to adapt to different types or different sizes of preset washing objects, support the preset washing object, expand the usage range of the profiling frame 551, and improve the adaptability between the profiling frame 551 and the preset washing object.

[0060] The kneading and washing structure further includes a limiting shaft 52, and the profiling frame 551 is arranged on the intermediate frame 553; the insertion plate 51 forms an insertion plate mounting cavity 515, and the limiting shaft 52 is arranged in the insertion plate mounting cavity 515; the intermediate frame 553 forms a shaft hole 5531, and the shaft hole 5531 is sleeved outside the limiting shaft 52;

[0061] When the washing tub and the insertion plate 51 rotate synchronously, under the action of the water flow in the washing tub, the profiling frame 551 and the intermediate frame 553 swing relative to the insertion plate 51; so that the intermediate frame 553 is reliably connected to the insertion plate 51;

[0062] The top wall of the insertion plate mounting cavity 515 forms a mounting cavity flat position hole 5151, and one end of the limiting shaft 52 forms a first flat position 521; the bottom wall of the insertion plate mounting cavity 515 forms a mounting cavity bottom hole 5152; one end of the limiting shaft 52 passes through the mounting cavity bottom hole 5152 to the mounting cavity flat position hole 5151, and at least a part of the first flat position 521 cooperates with the flat position hole, so that one end of the limiting shaft 52 is arranged at the top wall of the insertion plate mounting cavity 515, and the other end of the limiting shaft 52 is arranged at the mounting cavity bottom hole 5152.

[0063] Furthermore, the bottom wall of the insertion plate mounting cavity 515 further forms an insertion plate mounting groove 5153, and the insertion plate mounting groove 5153 is located at the bottom of the mounting cavity bottom hole 5152 and communicates with the mounting cavity bottom hole 5152; the other end of the limiting shaft 52 forms a mounting table 522; the insertion plate mounting groove 5153 cooperates with the mounting table 522, so that the other end of the limiting shaft 52 is arranged at the bottom wall of the insertion plate mounting cavity 515; both ends of the limiting shaft 52 are respectively arranged in the insertion plate mounting cavity 515 through corresponding structures, and the connection is reliable.

[0064] Aiming at the problem that it is not conducive to washing the preset washing object when the profiling frame 551 can rotate at a relatively large angle, this embodiment proposes that a swing limiting structure is further formed between the limiting shaft 52 and the intermediate frame 553, and the swing limiting structure enables the intermediate frame 553 to swing relative to the limiting shaft 52 within a preset swing angle; the movement freedom degree of the profiling frame 551 is increased, so that washing water with different flow directions and sizes contacts the preset washing object, and the preset washing object can be washed comprehensively and thoroughly.

[0065] Furthermore, the swing limiting structure includes a first limiting bushing 531, a second limiting bushing 532 and a limiting boss 523; a first limiting bushing 531 is arranged at one end of the shaft hole 5531 close to the mounting cavity flat position hole 5151, and a second limiting bushing 532 is arranged at one end of the shaft hole 5531 close to the mounting cavity bottom hole 5152; a limiting boss 523 is formed at one end of the limiting shaft 52 close to the mounting cavity bottom hole 5152, and the limiting boss 523 is located at the top of the mounting table 522; one end of the limiting shaft 52 passes through the first limiting bushing 531, and the other end of the limiting shaft 52 passes through the mounting cavity bottom hole 5152, so that the limiting boss 523 cooperates with the second limiting bushing 532;

[0066] In addition, the first limit bushing 531 forms a first bushing flat position hole; the limit boss 523 forms a second flat position 524, and the second limit bushing 532 forms a second bushing flat position hole; another part of the first flat position 521 cooperates with the first bushing flat position hole, and the second flat position 524 cooperates with the second bushing flat position hole, so that the limit shaft 52 limits the middle frame 553; ensuring that the middle frame 553 swings within a certain range and avoiding the problem that the swing angle of the middle frame 553 is too large, which instead reduces the washing effect.

[0067] <Scrubbing board and baffle>

[0068] Aiming at the problems of incomplete and incomplete washing of the preset washing object, this embodiment proposes that the washing assembly further includes a scrubbing board, which is arranged on the plug board 51 and below the profiling frame 551, and the scrubbing board is formed with scrubbing ribs or scrubbing protrusions for washing the preset washing object.

[0069] Furthermore, both the scrubbing ribs or the scrubbing protrusions include a plurality of them, and the free ends of the plurality of scrubbing ribs or the plurality of scrubbing protrusions form a structure adapted to the preset washing object; the scrubbing ribs or the scrubbing protrusions create a gap between the scrubbing board and the preset washing object, and the washing water can enter this gap and then, through the scrubbing action of the scrubbing ribs or the scrubbing protrusions, improve the washing effect.

[0070] Aiming at the problem that the washing force of the washing water on the preset washing object is small during the rotation of the washing tub, this embodiment proposes that the middle frame 553 is formed with a baffle 5532, and the baffle 5532 extends in a direction away from the side wall of the middle frame 553; the plug board 51 is formed with a baffle avoidance cavity 517, and the baffle avoidance cavity 517 communicates with the plug board installation cavity 515; when the profiling frame 551 swings with the washing water in the washing tub, the baffle 5532 can pass through the baffle avoidance cavity 517 and swing with the middle frame 553 to deflect the washing water towards the preset washing object, increasing the contact probability between the washing water and the preset washing object.

[0071] Furthermore, as Figure 5c shown, the middle frame 553 is a cylindrical structure; the baffle 5532 includes a plurality of them, and the plurality of baffles 5532 are arranged along the circumference of the middle frame 553; among two adjacent baffles 5532, the angle between one baffle 5532 and the preset plane is an acute angle, and the angle between the other baffle 5532 and the preset plane is an obtuse angle; the preset plane is the symmetry plane of the two end faces of the middle frame 553; when the washing tub rotates clockwise or counterclockwise, there is always one baffle 5532 that can deflect the washing water towards the preset washing object, improving the washing effect.

[0072] <Plug board heart-shaped beam and gland>

[0073] As Figure 4b and Figure 4cAs shown, to address the problem of unstable fixation of the preset washing object, in this embodiment, a gland 562 and a core beam 561 of the plug board are provided at the top of the plug board 51, and the core beam 561 of the plug board is located at the bottom of the gland 562; a part of the preset washing object is provided between the gland 562 and the core beam 561 of the plug board, playing a good fixing role;

[0074] Preferably, the core of the bra fits on the core beam 561 of the plug board, and the two cups of the bra are respectively sleeved on the outer sides of the two rubbing outer layers 552, and the gland 562 is rotated to cover the core of the bra.

[0075] On both sides of the bottom of the gland 562, gland protrusions are formed; the profiling frame 551 can swing relative to the gland 562, so that the gland protrusions contact the preset washing object and wash the preset washing object; the gland protrusions can wash the top of the preset washing object, and the gland protrusions contact and rub the preset washing object for washing, and the washing water contacts the preset washing object for hydraulic washing.

[0076] To address the problem that the plug board 51 is prone to deformation due to its weak structural strength, in this embodiment, a plurality of wall strengthening ribs are formed on the side wall, top wall and bottom wall of the plug board 51, and the plurality of wall strengthening ribs are staggered to improve the structural strength of the plug board 51; the plug board installation cavity 515 is located in the middle of the plug board 51, and a plurality of middle strengthening ribs are formed on the outside of the plug board installation cavity 515, and adjacent middle strengthening ribs enclose the plug board water passing holes 516; the middle strengthening cavity encloses the plug board water passing holes 516; on the one hand, the structural strength of the plug board 51 can be strengthened, and on the other hand, the washing water on one side of the plug board 51 can enter the other side of the plug board 51 through the plug board water passing holes 516, so as to form washing water with different flow states and increase the washing power of the washing water.

[0077] <Rubbing outer layer>

[0078] As Figure 7a 、 Figure 7b and Figure 7c shown, the rubbing structure further includes a rubbing outer layer 552, and the rubbing outer layer 552 is sleeved on the outer side surface of the profiling frame 551. The corresponding rubbing outer layer 552 can be sleeved on the profiling frame 551 according to actual needs to adapt to different types or different sizes of preset washing objects; the preset washing object is sleeved on the outer side surface of the rubbing outer layer 552, and the rubbing outer layer 552 plays a washing role on the preset washing object, expanding the use range of the rubbing outer layer 552 and improving the adaptability between the rubbing outer layer 552 and the profiling frame;

[0079] To address the problem of poor washing effect of the outer rubbing and washing layer 552, in this embodiment, rubbing and washing protrusions 5521 or rubbing and washing ribs 5521 are formed on the outer side surface of the outer rubbing and washing layer 552, and the free ends of the rubbing and washing protrusions 5521 or rubbing and washing ribs 5521 form a structure adapted to the preset washing object; a certain interval is formed between the outer side surface of the outer rubbing and washing layer 552 and the inner side surface of the preset washing object, washing water can enter the interval, and there is a frictional movement between the rubbing and washing protrusions 5521 or rubbing and washing ribs 5521 and the preset washing object, thereby washing the preset washing object fully and thoroughly; in addition, the preset washing object can be supported to prevent the preset washing object from deforming during the washing process;

[0080] A plurality of rubbing and washing protrusions 5521 form a plurality of groups of rubbing and washing protrusions, and the plurality of rubbing and washing protrusions 5521 in each group of rubbing and washing protrusions are arranged alternately along the circumferential direction of the corresponding circle; the circles where different groups of rubbing and washing protrusions are located are concentric and spaced apart. Preferably, the rubbing and washing protrusions 5521 are of a columnar or conical structure.

[0081] The rubbing and washing ribs 5521 are of an annular structure and include a plurality of them, and the plurality of rubbing and washing ribs 5521 are concentric and spaced apart. Or, the rubbing and washing ribs 5521 are of a linear structure or an arc-shaped structure, and the rubbing and washing ribs 5521 include a plurality of them, and the plurality of rubbing and washing ribs 5521 are arranged alternately along the outer side surface of the outer rubbing and washing layer 552.

[0086] <Connection 1 between the mounting rack and the plug board>
