Description

Technical Field

[0001] This invention belongs to the field of washing technology, and particularly relates to an underwear washing device and a washing machine. Background Technology

[0002] Washing machines, with their functions of washing, drying, and disinfecting, have greatly facilitated people's lives and have gradually become an indispensable household appliance. As people's living standards improve, they have higher requirements for washing machines, such as washing machines specifically designed for washing underwear. Currently, there are few types of small washing machines available, and they are not specifically designed for washing underwear, mainly using pulsator or drum washing. However, due to the lack of necessary support structures, underwear may deform and wear during the washing process, and the weak washing force results in poor washing performance. Summary of the Invention

[0012] During washing, the outer wall of the first contoured structure fits against the inner wall of the corresponding cup, and the squeezing part passes through the corresponding clearance hole and squeezes the corresponding first contoured structure, so that the outer wall of the first contoured structure can wash the inner wall of the corresponding cup.

[0013] Further optionally, the support cover forms two second contoured structures, both of which protrude from the outer arc surface of the main body of the support cover, and the two second contoured structures are adapted to the two cups of the bra; each second contoured structure has the same convex direction as the corresponding first contoured structure;

[0014] During washing, the inner wall of the second contoured structure fits against the outer wall of the corresponding cup, and the squeezing part squeezes the corresponding first contoured structure, so that the inner wall of the second contoured structure can wash the outer wall of the corresponding cup.

[0015] Alternatively, both the first contouring structure and the extrusion section are flexible designs, and the second contouring structure is a hollow structure.

[0016] Further optionally, the mounting frame has a first limiting structure on the side away from the support frame; the washing rack also includes a connecting beam, the two ends of which are respectively connected to the two extrusion parts, and the connecting beam has a second limiting structure; the first limiting structure and the second limiting structure cooperate to allow the washing rack to slide relative to the mounting frame.

[0017] Further optionally, the washing rack also includes two connecting posts, which are respectively arranged in correspondence with the two squeezing parts; one end of each connecting post is disposed on the main body of the washing rack, and the other end of each connecting post extends toward the corresponding clearance hole and connects to the corresponding squeezing part;

[0018] When the main body of the washing rack moves, the squeezing part can move closer to or further away from the corresponding first contoured structure and exert a squeezing force on the bra.

[0019] Optionally, the squeezing washing mechanism further includes a cam assembly, which includes a driving cam and a driven cam arranged coaxially. One end of the driving cam is connected to one end of the driven cam, and the other end of the driven cam is fixedly connected to the main body of the washing rack.

[0020] When the active cam rotates, the driven cam and the main body of the washing rack can reciprocate along the axis of the driven cam.

[0021] Further optionally, the driven cam has a first guide structure, and the end of the driving cam that cooperates with the driven cam has a second guide structure; the first guide structure and the second guide structure cooperate to allow the driven cam to reciprocate relative to the driving cam along the axis of the driven cam.

[0027] When the output shaft of the clutch is connected to the active cam drive, the output shaft of the clutch can drive the active cam to rotate, thereby causing the washing rack to reciprocate, so that the squeezing part can apply a squeezing force to the bra in the clamping space;

[0028] When the output shaft of the clutch is connected to the drain bucket drive, the output shaft of the clutch can drive the rotating mechanism and the support mechanism to rotate synchronously, so that the rotating mechanism can exert a rotational centrifugal force on the bra in the clamping space.

[0029] The present invention also provides a washing machine, including a washing tub and the underwear washing device described in any of the above claims; the support mechanism, the squeezing washing mechanism and the rotating mechanism of the underwear washing device are rotatably disposed within the washing tub.

[0030] Compared with the prior art, the main advantages of the present invention are:

[0031] (1) The support component is set on the mounting frame and forms a clamping space for clamping the underwear, which effectively supports, shapes and limits the underwear, avoids deformation and surface wear of the underwear during washing, and solves the problem of underwear deformation caused by movement and turning during washing; the squeezing part moves and applies squeezing force to the underwear in the clamping space, resulting in strong washing force and thorough washing, solving the problem of incomplete washing caused by weak washing force.

[0032] (2) Both the first and second contour structures are adapted to the two cups of the bra, which greatly preserves the original shape of the bra and provides a good limiting effect to prevent the bra from moving during washing. During washing, the squeezing part passes through the corresponding clearance hole and squeezes the corresponding first contour structure, so that the outer wall of the first contour structure can wash the inner wall of the corresponding cup. This avoids interference between the squeezing part and the mounting bracket when the squeezing part moves. The squeezing part does not directly act on the bra, reducing the wear and tear on the bra and effectively protecting it. The large washing surface of the squeezing part improves the washing effect.

[0033] (3) The first limiting structure and the second limiting structure work together. When the active cam rotates, the driven cam reciprocates along the axis of the driven cam, allowing the washing rack to slide relative to the mounting frame, thus improving the accuracy of the washing rack's movement. The drain bucket is encircled on the outer periphery of the support mechanism and is linked to the mounting frame. When the drain bucket rotates, it can drive the support mechanism and the reinforcing plate to rotate synchronously, allowing the washing water to wash the outer wall of the bra cup. Combined with squeezing washing, it achieves a comprehensive and thorough washing of the bra. Attached Figure Description

[0055] The following specific embodiments illustrate the implementation 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 only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0058] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0059] The existing small washing machine products are limited in variety and are not specifically designed for washing underwear. They mainly use pulsator or drum washing machines to wash underwear; however, due to the lack of necessary support structures, underwear may be deformed and worn during the washing process, and the washing may not be thorough.

[0060] This invention creatively provides an underwear washing device, including a support mechanism and a squeezing washing mechanism. The support mechanism includes a mounting frame and a support component. The support component is mounted on the mounting frame and forms a clamping space. The clamping space can support, shape, and clamp the underwear, preventing the underwear from moving and deforming during washing, reducing surface wear, and solving the problems of easy deformation and significant surface wear when washing underwear. The squeezing washing mechanism includes a washing rack. When the washing rack moves, the squeezing part can apply a squeezing force to the underwear in the clamping space, resulting in a strong washing effect and solving the problem of incomplete washing due to weak washing effect.

[0061] Example 1

[0062] <Underwear Washing Unit>

[0063] like Figure 1 , Figure 2a , Figure 2b and Figure 2c As shown, this embodiment provides an underwear washing device, including:

[0064] The support mechanism 1 includes a mounting frame 13 and a support component. The support component is mounted on the mounting frame 13 and located on one side of the mounting frame 13. The main structure of the support component is adapted to the structure of the mounting frame 13, and the mounting frame 13 provides support for the support component. The support component forms a clamping space, which positions and limits the underwear, preventing deformation and surface wear of the underwear during washing and solving the problem of underwear deformation caused by movement and tumbling during washing.

[0065] The squeezing washing mechanism 2 includes a washing rack 21, which is movably disposed on the other side of the mounting frame 13 and includes a squeezing part 211, which is disposed on the main body 214 of the washing rack and close to the support assembly.

[0066] When the washing rack 21 moves, the squeezing part 211 can exert a squeezing force on the underwear in the clamping space. The squeezing force is strong, the washing is thorough, and the problem of incomplete washing caused by weak washing force is solved. The dehydration is also thorough, solving the problem of incomplete dehydration.

[0067] like Figures 3a to 3h As shown, in view of the problem that the structure of the clamping space is not compatible with the structure of the underwear, resulting in large deformation of the underwear during washing, this embodiment proposes that the support component includes a support frame 11 and a support cover 12. The support frame 11 is set on the mounting frame 13, and the support cover 12 covers the support frame 11, and a clamping space is formed between the support cover 12 and the support frame 11.

[0068] The main body 112 of the support frame, the main body 122 of the support cover, and the mounting frame 13 are all arc-shaped structures. The structures of the main body 112 of the support frame, the main body 122 of the support cover, and the mounting frame 13 are adapted to the main structure of the underwear. The main body 112 of the support frame is attached to the mounting frame 13, and the main body 122 of the support cover is attached to the main body 112 of the support frame, so that the clamping space has an effective supporting, shaping, and limiting effect on the underwear.

[0069] Furthermore, the underwear is a bra; the support frame 11 forms two first contoured structures 111, both of which protrude from the outer arc surface of the main body 112 of the support frame, and the two first contoured structures 111 are adapted to the two cups of the bra. The two first contoured structures 111 are symmetrically arranged with respect to the central axis of the main body 112 of the support frame. When the bra is placed in the clamping space, the positions of the two first contoured structures 111 correspond exactly to the positions of the two cups, so that the two first contoured structures 111 have a larger contact area with the inner walls of the two cups of the bra, thereby improving the support and limiting effect of the two first contoured structures 111 on the two cups of the bra.

[0070] The mounting bracket 13 has two clearance holes 131, both of which pass through both sides of the mounting bracket 13, and the two clearance holes 131 are provided in a one-to-one correspondence with the two first contour structures 111.

[0071] Two compression parts 211 are provided, and the structure of the two compression parts 211 is adapted to the two cups of the bra; the two compression parts 211 are correspondingly provided with two clearance holes 131, and the structure of each compression part 211 is adapted to the structure of the corresponding clearance hole 131, so that the compression part 211 can be inserted into the corresponding clearance hole 131 to avoid interference between the compression part 211 and the mounting bracket 13 when it moves; each compression part 211 has the same convex direction as the corresponding first contouring structure 111, so that the compression part 211 can effectively act on the corresponding first contouring structure 111, causing the first contouring structure 111 to deform or move relative to the corresponding cup, thereby washing the corresponding cup;

[0072] Specifically, the cross-sectional dimension of the clearance hole 131 is larger than the cross-sectional dimension of the extrusion part 211. When the extrusion part 211 moves, the extrusion part 211 does not contact the hole wall of the clearance hole 131 and does not contact other parts of the mounting bracket 13, so that the extrusion part 211 can smoothly extrude the corresponding first contour structure 111.

[0073] The support cover 12 has two second contoured structures 121, both of which protrude from the outer arc surface of the main body 122 of the support cover and are adapted to the two cups of the bra. The two second contoured structures 121 are symmetrically arranged with respect to the central axis of the main body 122 of the support cover. Each second contoured structure 121 has the same convex direction as the corresponding first contoured structure 111. The two second contoured structures 121 limit the two cups of the bra.

[0074] During washing, when the bra is placed in the clamping space, the outer wall of the first contouring structure 111 fits against the inner wall of the corresponding cup, and the inner wall of the second contouring structure 121 fits against the outer wall of the corresponding cup, greatly preserving the original shape of the bra and providing excellent restraint. The squeezing part 211 passes through the corresponding clearance hole 131 and squeezes the corresponding first contouring structure 111, allowing the outer wall of the first contouring structure 111 to wash the inner wall of the corresponding cup, and the inner wall of the second contouring structure 121 to wash the outer wall of the corresponding cup. The squeezing part 211 does not directly act on the bra, reducing wear and tear and effectively protecting the bra. The large washing surface of the squeezing part 211 improves the washing effect.

[0075] It should be noted that the squeezing part 211 is inserted into the corresponding clearance hole 131 during reciprocating motion, or the squeezing part 211 is at least partially disposed in the corresponding clearance hole 131 when stationary; this ensures that the squeezing part 211 can squeeze the corresponding first contour structure 111 during reciprocating motion without interfering with the hole wall of the corresponding clearance hole 131; preferably, the squeezing part 211 is always disposed in the corresponding clearance hole 131, which results in a better squeezing and washing effect.

[0076] In any of the above embodiments, the support cover 12 is rotatably disposed relative to the support frame 11 for easy user operation; the support cover 12 has a first state and a second state. When the support cover 12 is in the first state, a clamping space is formed between the support cover 12 and the support frame 11; when the support cover 12 is in the second state, the support cover 12 removes the clamping limit on the bra, and the bra can be placed on the support frame 11 or removed from the support frame 11.

[0077] To address the issue of incomplete washing when bras are placed in the clamping space, this embodiment proposes that the first contouring structure 111 and / or the second contouring structure 121 are both openwork structures. During washing, the washing water can enter the clamping space through the openwork structure and act on the bra, allowing the washing water to fully contact the inner and outer walls of the bra, thereby improving the washing ratio. Preferably, both the first contouring structure 111 and the second contouring structure 121 are openwork structures.

[0078] It should be noted that the support frame 11 can be a one-piece structure or a split structure; when the support frame 11 is a one-piece structure, two first contouring structures 111 protrude from the main body 112 of the support frame to form a split structure; when the support frame 11 is a split structure, the main body 112 of the support frame forms two first annular grooves, and the two first contouring structures 111 are detachably set at the corresponding first annular grooves. According to actual needs, first contouring structures 111 of different sizes can be set at the corresponding first annular grooves to adapt to bras of different sizes.

[0079] The support cover 12 can be a one-piece structure or a split structure. When the support cover 12 is a one-piece structure, two second contouring structures 121 protrude from the main body 122 of the support cover. Only one end of the support cover 12 needs to be hinged to the support frame 11 or the mounting frame 13. When the support cover 12 is a split structure, the main body 122 of the support cover forms two second annular grooves. The two second contouring structures 121 are detachably set at the corresponding second annular grooves. According to actual needs, the second contouring structures 121 of different sizes can be set at the corresponding second annular grooves to adapt to bras of different sizes.

[0080] When the washing rack 21 moves, the squeezing part 211 squeezes the corresponding first contouring structure 111, causing the first contouring structure 111 to wash the corresponding bra cup. To address the issue of bra wear and tear when the support frame 11 is used for washing, this embodiment proposes that the first contouring structure 111 and / or the entire support frame 11 be of flexible design, and the entire washing rack 21 or the squeezing part be of flexible design. Specifically, when the first contouring structure 111 is of flexible design, the squeezing part is also of flexible design. When the squeezing part 211 squeezes the corresponding first contouring structure 111, it deforms the first contouring structure 111, thereby washing the corresponding bra cup.

[0081] like Figure 3f , Figure 3g , Figure 4a and Figure 4bAs shown, to address the issue of unstable movement of the washing rack 21, this embodiment proposes that a first limiting structure 132 be formed on the side of the mounting frame 13 away from the support frame 11; the washing rack 21 also includes a connecting beam 212, with two pressing parts 211 connected to both ends of the connecting beam 212; preferably, the connecting beam 212 is an elastic body. The connecting beam 212 is formed with a second limiting structure, which cooperates with the first limiting structure 132 to allow the washing rack 21 to slide relative to the mounting frame 13;

[0082] Specifically, the first limiting structure 132 is located between the two clearance holes 131, and the first limiting structure 132 is a limiting post; the connecting beam 212 is an arc-shaped structure, one end of the connecting beam 212 passes through one clearance hole 131 and connects to the corresponding extrusion part 211, and the other end of the connecting beam 212 passes through another clearance hole 131 and connects to the corresponding extrusion part 211; the second limiting structure is located between the two extrusion parts 211, and the second limiting structure is a limiting groove; the limiting post and the limiting groove have the same extension direction, and the limiting post is locked in the limiting groove, so that the washing rack 21 can slide relative to the mounting frame 13 in a directional manner, so that the extrusion part 211 can move accurately in the corresponding clearance hole 131, and avoid the washing rack 21 moving unstably, which would cause the extrusion part 211 to interfere with the mounting frame 13 when it moves.

[0083] Furthermore, the washing rack 21 also includes two connecting posts 213, which are arranged one-to-one with two extrusion parts 211. The two extrusion parts 211 are arranged side by side, and the two connecting posts 213 are arranged side by side. The extrusion parts 211, the connecting posts 213 and the main body of the washing rack are arranged sequentially from top to bottom. One end of each connecting post 213 is provided on the main body 214 of the washing rack, and the other end of each connecting post 213 extends toward the corresponding clearance hole 131 and connects to the corresponding extrusion part 211.

[0084] When the main body 214 of the washing rack moves, the squeezing part 211 can approach or move away from the corresponding first contour structure 111 and apply a squeezing force to the bra, which can squeeze and wash the bra or dehydrate the bra.

[0085] To address the problem of unstable movement of the washing rack 21 due to the complex transmission mechanism structure, this embodiment proposes that the squeezing washing mechanism 2 further includes a cam assembly. The cam assembly includes a driving cam 22 and a driven cam 23 coaxially arranged. One end of the driving cam 22 is connected to one end of the driven cam 23, and the other end of the driven cam 23 is fixedly connected to the main body 214 of the washing rack. Specifically, the main body 214 of the washing rack has a cylindrical structure, and the axis of the main body 214 of the washing rack is aligned with the axis of the driven cam 23.

[0086] When the driving cam 22 rotates, the driven cam 23 and the main body 214 of the washing rack can reciprocate along the axis of the driven cam 23;

[0087] Specifically, the driving cam 22 has a first convex-concave portion at the end that mates with the driven cam 23, and the driven cam 23 has a second convex-concave portion at the end that mates with the driving cam 22. The first and second convex-concave portions can be convex-concave engaged. The driving cam 22 and the driven cam 23 have a first engagement state and a second engagement state. When the driving cam 22 and the driven cam 23 are in the first engagement state, the convex surface of the first convex-concave portion engages with the convex surface of the second convex-concave portion. When the driving cam 22 and the driven cam 23 are in the second engagement state, the convex surface of the first convex-concave portion engages with the concave surface of the second convex-concave portion, and the concave surface of the first convex-concave portion engages with the convex surface of the second convex-concave portion.

[0088] When the driving cam 22 and the driven cam 23 switch from the first engagement state to the second engagement state, the driving cam 22 and the driven cam 23 move closer to each other, and the driven cam 23 and the washing rack 21 move away from the support frame 11.

[0089] When the driving cam 22 and the driven cam 23 switch from the second engagement state to the first engagement state, the driving cam 22 and the driven cam 23 move away from each other, and the driven cam 23 drives the washing rack 21 to move towards the side closer to the support frame 11;

[0090] Furthermore, at least one set of the first convex and concave portions and the second convex and concave portions are provided; wherein, each set of the first convex and concave portions corresponds to one set of the second convex and concave portions; an elastic element is connected between the first limiting structure 132 and the second limiting structure; when the active cam 22 rotates, causing the active cam 22 and the driven cam 23 to switch from the second engagement state to the first engagement state, the convex surface of the first convex and concave portion gradually engages with the convex surface of the second convex and concave portion, the driven cam 23 moves upward along the axis of the driven cam 23, the elastic element is compressed and stores energy, until the active cam 22 and the driven cam 23 are in the first engagement state; the active cam 22 continues to rotate, the elastic element releases energy and drives the washing rack and the driven cam 23 to move downward along the axis of the driven cam 23, the convex surface of the first convex and concave portion gradually engages with the concave surface of the second convex and concave portion, the concave surface of the first convex and concave portion gradually engages with the convex surface of the second convex and concave portion, and the active cam 22 and the driven cam 23 gradually switch from the first engagement state to the second engagement state.

[0091] In order to improve the smoothness of the transmission between the driving cam 22 and the driven cam 23, in this embodiment, the convex surface of the first convex-concave part and the concave surface of the first convex-concave part are smoothly transitioned, and the convex surface of the second convex-concave part and the concave surface of the second convex-concave part are smoothly transitioned.

[0092] To address the issue of unstable motion in the driven cam 23, this embodiment proposes that the driving cam 22 is located at the bottom of the driven cam 23; the driven cam 23 has a first guide structure 231, and the end of the driving cam 22 that mates with the driven cam 23 has a second guide structure 221; the first guide structure 231 and the second guide structure 221 cooperate to allow the driven cam 23 to reciprocate relative to the driving cam 22 along the axis of the driven cam 23; specifically, the first guide structure 231 is a guide hole, the axis of which is aligned with the axis of the driven cam 23; the second guide structure 221 is a guide post, the axis of which is aligned with the axis of the driving cam 22; one end of the guide post is connected to the driving cam 22, and the other end of the guide post is disposed in the guide hole; when the driven cam 23 slides relative to the driving cam 22, the guide hole mates with the guide post.

[0093] like Figure 1 , Figure 5 and Figure 6 As shown, to address the problem that washing water cannot clean the outer wall of the bra, this embodiment proposes that the underwear washing device further include a rotating mechanism 3. The rotating mechanism 3 includes a drain bucket 31 and a reinforcing plate 32. The drain bucket 31 is arranged around the outer periphery of the support mechanism 1, and the drain bucket 31 is linked to the mounting frame 13. Specifically, the mounting frame 13 is arranged on the bottom wall of the drain bucket 31 and located inside the drain bucket 31. The drain bucket 31 supports the mounting frame 13, and the axis of the drain bucket 31 is... Aligned with the axis of the active cam 22; the side wall of the drain bucket 31 has a drain hole 311, through which the washing water on the outside of the drain bucket 31 can enter the inside of the drain bucket 31; a first rib 312 is provided on the inner side of the side wall of the drain bucket 31, the first rib 312 protrudes into the inside of the drain bucket 31 and is located close to the support assembly; when the drain bucket 31 rotates, the first rib 312 can push the washing water on the inside of the drain bucket 31 toward the support cover 12, thereby washing the outer wall of the bra;

[0094] A reinforcing plate 32 is disposed at the bottom of the inner side of the drain bucket 31 and connected to the bottom wall of the drain bucket 31 to enhance the rigidity of the drain bucket 31 and support the support mechanism 1; a second rib 321 is formed on the side of the reinforcing plate 32 facing the top of the drain bucket; when the drain bucket 31 rotates, the second rib 321 can push the washing water inside the drain bucket 31 toward the support frame 11, thereby washing the inner wall of the bra; the first rib 312 and the second rib 321 have an arc-shaped, strip-shaped or wave-shaped structure, and the first rib 312 and the second rib 321 form a turbulent rinsing effect, which can improve the washing effect;

[0095] Depending on the state of the drain tub 31, the lingerie washing device has multiple washing modes:

[0096] When the drain bucket 31 rotates, it can drive the support mechanism 1 and the reinforcing plate 32 to rotate synchronously, so that the rotating mechanism 3 applies a centrifugal force to the bra in the clamping space, which can rotate and wash the bra or dehydrate the bra; when the drain bucket 31 does not rotate, the active cam 22 rotates, and then the driven cam 23 and the washing rack 21 reciprocate along the axis of the driven cam 23, so that the squeezing part 211 applies a squeezing force to the bra in the clamping space, which can squeeze and wash the bra or dehydrate the bra;

[0097] Specifically, the drain bucket 31 is designed as a washing space to wash and dehydrate the bra, while the washing space can also prevent the bra straps from getting tangled with the first rib 312.

[0098] To address the issue that it is not possible to selectively squeeze and rotate for washing based on actual conditions, this embodiment proposes that the reinforcing plate 32 forms a limiting hole 32, and the limiting hole 32 is rotatably provided with an active cam 22;

[0099] The lingerie washing device also includes a drive mechanism 4, which includes a clutch 41. The output shaft 411 of the clutch can be selectively connected to the drive cam 22 or to the drain tub 31. Specifically, when the output shaft 411 of the clutch is connected to the drive cam 22, the output shaft 411 of the clutch can drive the drive cam 22 to rotate, thereby causing the washing rack 21 to reciprocate, so that the squeezing part 211 can apply a squeezing force to the bra in the clamping space.

[0100] When the output shaft 411 of the clutch is driven to connect with the drain bucket 31, the output shaft 411 of the clutch can drive the rotating mechanism 3 and the support mechanism 1 to rotate synchronously, so that the rotating mechanism 3 can apply a rotational force to the bra in the clamping space.

[0101] In summary, the support cover 12, support frame 11, mounting frame 13, washing rack 21, cam assembly, reinforcing plate 32, drain bucket 31, and drive mechanism 4 are arranged sequentially from top to bottom; when the rotating mechanism 3 and the support mechanism 1 rotate synchronously, the bra can be rotated for washing or for dehydration; when the active cam 22 rotates, the washing rack 21 reciprocates relative to the mounting frame 13, which can squeeze the bra for washing or for dehydration.

[0102] Washing Machine

[0103] like Figure 7 , Figure 8a and Figure 8b As shown, this embodiment also provides a washing machine 6, including a washing tub 5 and the underwear washing device described in any of the above-mentioned embodiments; the support mechanism 1, the squeezing washing mechanism 2 and the rotating mechanism 3 of the underwear washing device are rotatably disposed in the washing tub 5.

[0104] Example 2

[0105] Unlike Embodiment 1, the washing rack 21 also includes two hydraulic rods and two hydraulic cylinders. The two hydraulic rods are arranged one-to-one with the two extrusion parts 211. The two extrusion parts 211 are arranged side by side, the two hydraulic rods are arranged side by side, and the two hydraulic cylinders are arranged side by side. The extrusion parts 211, hydraulic rods, and hydraulic cylinders are arranged sequentially from top to bottom. One end of each hydraulic rod is disposed in the corresponding hydraulic cylinder, and the other end of each hydraulic rod extends toward the corresponding clearance hole 131 and connects to the corresponding extrusion part 211. A piston is formed between the hydraulic rod and the hydraulic cylinder, and the piston divides the hydraulic cylinder into a first cavity and a second cavity. The side wall of the hydraulic cylinder forms a first water inlet to the first cavity and a second water inlet to the second cavity. During washing, water is supplied to the first cavity and water is drained from the second cavity, which allows the hydraulic rods to extend, thereby causing the extrusion parts 211 to extrude the first contour structure 111. Water is supplied to the second cavity and water is drained from the first cavity, which allows the hydraulic rods to retract, thereby causing the extrusion parts 211 to move away from the first contour structure 111.

[0106] Example 3

[0107] Unlike Embodiment 1, the lingerie washing device also includes a drive mechanism 4, which includes two hydraulic motors. The two hydraulic motors are arranged one-to-one with two squeezing parts 211, and the two squeezing parts 211 are arranged side by side. The output shaft of each hydraulic motor is drivenly connected to the corresponding squeezing part 211. During washing, the two hydraulic motors are rotated, which in turn causes the corresponding squeezing parts 211 to rotate, so that the squeezing parts 211 apply a squeezing washing force to the bra cups.
