[0066] <Underwear washing machine>

[0067] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides an underwear washing device, which includes:

[0068] The support mechanism 1 includes a support frame 11 and a support cover 12. The support frame 11 is formed with a plurality of spray holes 112. The support cover 12 covers one side of the support frame 11, and a clamping space is formed between the support cover 12 and the support frame 11. The structure of the clamping space is adapted to the structure of the underwear, so that the clamping space can provide effective support, shaping, and positioning for the underwear, thereby preventing deformation, movement, and friction of the underwear during washing, which may cause wear on the underwear surface. The clamping space is connected to one end of each spray hole 112.

[0069] The spray washing mechanism 2 includes a spray element 21, which is disposed on the support frame 11 and located on the other side of the support frame 11. That is, the spray element 21 and the support cover 12 are disposed on opposite sides of the support frame 11. A spray chamber 211 is formed between the spray element 21 and the support frame 11. The spray chamber 211 is connected to the other end of each spray hole 112. That is, the spray chamber 211 is connected to the clamping space through the multiple spray holes 112.

[0070] The pressure of the spray chamber 211 can be controlled to change periodically, so that the washing water in the spray chamber 211 can be intermittently sprayed into the clamping space through the spray hole 112, so as to implement intermittent spray washing effect on the underwear in the clamping space; the washing effect is strong, the washing coverage is large, and the washing efficiency is high. Different washing effects can be achieved by adjusting the pressure of the spray chamber 211.

[0071] Specifically, when the current pressure of the spray chamber 211 is less than the preset pressure, the washing water outside the spray chamber 211 can enter the spray chamber 211; when the current pressure of the spray chamber 211 is greater than the preset pressure, the washing water in the spray chamber 211 can be sprayed toward the clamping space through the spray hole 112; wherein the preset pressure is determined according to the volume of the spray chamber 211, the number of the spray holes 112 and the size of the spray holes 112.

[0072] like Figure 3 As shown, in order to solve the problem of complex component structure required for spraying the washing water in the spray chamber 211 into the clamping space, this embodiment proposes that the spray part 21 is further formed with a piston cylinder 212, one end of the piston cylinder 212 is communicated with the spray chamber 211, and the other end of the piston cylinder 212 extends in the direction away from the support frame 11; a water inlet hole is formed on the side wall of the piston cylinder 212; the spray washing mechanism 2 also includes a washing rack 22, and the washing rack 22 is formed with a piston rod 222, and the piston rod 222 is arranged in the piston cylinder 212; specifically, the piston rod 222 is provided with a piston 221 at one end near the piston cylinder 212, and the piston 221 and the side wall of the piston cylinder 212 form a pressure chamber, which is communicated with the water inlet hole, and the washing water outside the piston cylinder 212 can enter the pressure chamber through the water inlet hole; the pressure chamber is communicated with the spray chamber 211; when the current pressure of the spray chamber 211 is less than the preset pressure, the washing water in the pressure chamber can enter the spray chamber 211;

[0073] When the piston rod 222 moves along the piston cylinder 212 in a direction away from the support frame 11, the washing water outside the piston cylinder 212 can enter the piston cylinder 212 through the water inlet hole; when the piston rod 222 moves along the piston cylinder 212 in a direction close to the support frame 11, the washing water in the piston cylinder 212 can enter the spray chamber 211, and then the washing water in the spray chamber 211 is sprayed into the clamping space through the spray hole 112; the movement of the piston rod 222 is stable, and by adjusting the speed of the piston rod 222, the speed of the washing water sprayed from the spray hole 112 can be adjusted to achieve different spray washing effects;

[0074] Specifically, a first one-way valve is provided at the water inlet, and a second one-way valve is provided at the connection between the piston cylinder 212 and the spray chamber 211; when the piston rod 222 moves along the piston cylinder 212 in the direction away from the support frame 11, the first one-way valve opens and the second one-way valve closes, and the washing water outside the piston cylinder 212 enters the piston cylinder 212 through the water inlet; when the piston rod 222 moves along the piston cylinder 212 in the direction close to the support frame 11, the first one-way valve closes and the second one-way valve opens, and the washing water in the piston cylinder 212 enters the spray chamber 211, and then the washing water in the spray chamber 211 is sprayed toward the underwear in the clamping space through the spray hole 112; the wear of the bra is reduced and the bra is effectively protected; different washing effects can be achieved by adjusting the pressure of the spray chamber 211.

[0075] like Figure 2 As shown, in order to solve the problem that the structure of the clamping space is not compatible with the structure of the underwear, which causes the underwear to be greatly deformed during washing, this embodiment proposes that the underwear is a bra; the support frame 11 includes two first profiling structures 111, the two first profiling structures 111 are adapted to the two cups of the bra and the two first profiling structures 111 are connected by a connecting beam 113; specifically, the connecting beam 113 is an arc structure, one end of the connecting beam 113 passes through an avoidance hole 131 and is connected to the corresponding first profiling structure 111, and the other end of the connecting beam 113 passes through The first profiling structures 111 are connected to the corresponding first profiling structures 111 through another avoidance hole 131. When the bra is placed in the clamping space, the positions of the two first profiling structures 111 correspond to the positions of the two cups. This increases the contact area between the two first profiling structures 111 and the inner side walls of the two cups of the bra, thereby improving the support and limiting effect of the two first profiling structures 111 on the two cups of the bra. Each first profiling structure 111 is formed with a plurality of spray holes 112, and the end of each spray hole 112 near the clamping space is connected to the clamping space.

[0076] Two spray elements 21 are provided, and the two spray elements 21 are arranged in a one-to-one correspondence with the two first profiling structures 111. A spray cavity 211 is formed between each spray element 21 and the corresponding first profiling structure 111, and the spray cavity 211 is connected to each corresponding spray hole 112. Each spray element 21 is formed with a piston cylinder 212, one end of which is connected to the corresponding spray cavity 211, and the other end of the piston cylinder 212 extends away from the corresponding first profiling structure 111.

[0077] Two piston rods 222 are provided, and the two piston rods 222 are arranged in a one-to-one correspondence with the two piston cylinders 212. The two piston rods 222 are arranged in parallel, and the two piston cylinders 212 are arranged in parallel. The first contoured structure 111, the spray chamber 211, the piston cylinder 212 and the piston rods 222 are arranged in sequence from top to bottom; the piston rods 222 can reciprocate along the corresponding piston cylinders 212, and then the washing water in the corresponding spray chamber 211 is sprayed toward the corresponding cup through each corresponding spray hole 112; on the one hand, the pressurized washing water acts on the cup to achieve a washing effect, and the washing water is sprayed toward different parts of the inner wall of the cup through different spray holes 112, so that the washing coverage is large and the washing is thorough; on the other hand, the washing water is in direct contact with the cup, avoiding the problem of large surface wear of the cup during friction washing.

[0078] Furthermore, the support cover 12 is formed with two second contoured structures 121, which are adapted to the two cups of the bra; when the bra is placed in the clamping space, the positions of the two second contoured structures 121 correspond to the positions of the two cups;

[0079] like Figure 2 As shown, the support mechanism 1 further includes a mounting frame 13, on which the support frame 11 and the support cover 12 are both arranged. Specifically, a connecting column 132 is formed on a side of the mounting frame 13 away from the support cover 12. The connecting column 132 extends in a direction away from the support cover 12 and is connected to the connecting beam 113 to achieve the connection between the support frame 11 and the mounting frame 13. Two first profiling structures 111 and two second profiling structures 121 are arranged in a one-to-one correspondence, and each first profiling structure 111 has the same convex direction as the corresponding second profiling structure 121. A clamping space is formed between the first profiling structure 111 and the corresponding second profiling structure 121.

[0080] During washing, the outer sidewall of the first profiling structure 111 fits in contact with the inner sidewall of the corresponding cup, and the inner sidewall of the second profiling structure 121 fits in contact with the outer sidewall of the corresponding cup.

[0081] In order to address the problem that the support frame 11 cannot play a good limiting role due to the unreasonable structural design of the mounting frame 13, this embodiment proposes that the mounting frame 13 is an arc-shaped structure, and the mounting frame 13 is formed with two avoidance holes 131. The two avoidance holes 131 are arranged in a one-to-one correspondence with the two first profiling structures 111, and the two avoidance holes 131 are located on both sides of the connecting column 132; the first profiling structure 111 and the corresponding spray chamber 211 are both located on one side of the mounting frame 13, and the piston cylinder 212 is passed through the corresponding avoidance hole 131 and extends to the other side of the mounting frame 13; in this way, on the one hand, a clamping space can be formed between the first profiling structure 111 and the second profiling structure 121, which plays a good supporting and limiting role on the bra; on the other hand, the piston rod 222 does not interfere with the mounting frame 13 when moving along the corresponding piston cylinder 212.

[0082] Furthermore, the main body 122 of the support cover is an arc-shaped structure, and the two second profiling structures 121 are both arranged to protrude from the outer arc surface of the main body 122 of the support cover. The structure of the main body 122 of the support cover is adapted to the structure of the mounting frame 13; when the bra is placed in the clamping space, the two cups are respectively arranged between the corresponding first profiling structure 111 and the second profiling structure 121, and the rest of the bra is arranged between the mounting frame 13 and the main body 122 of the support cover; in this way, support and position limiting of the entire bra are achieved; the original shape of the bra is greatly guaranteed, and a good position limiting effect is played on the bra, thereby preventing the bra from moving during washing.

[0083] In any of the above embodiments, the support cover 12 is rotatably arranged relative to the support frame 11, which is convenient for 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 cancels the clamping limit on the bra, and the bra can be placed on the support frame 11 or taken out from the support frame 11;

[0084] To address the problem of incomplete washing when the bra is placed in the clamping space, this embodiment proposes that the second contoured structure 121 is a hollow structure; during washing, the washing water can enter the clamping space through the hollow structure and act on the bra, so that the washing water is in full contact with the inner and outer walls of the bra, thereby improving the cleaning ratio.

[0085] It should be noted that the support cover 12 can be an integral structure or a split structure; when the support cover 12 is an integral structure, the two second contour structures 121 protrude from the main body 122 of the support cover, and it is only necessary to hinge one end of the support cover 12 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 is formed with two second annular grooves, and the two second contour structures 121 can be detachably arranged at the corresponding second annular grooves. According to actual needs, second contour structures 121 of different sizes can be arranged at the corresponding second annular grooves to adapt to bras of different sizes.

[0086] In order to solve the problem of complex transmission mechanism structure required for the reciprocating motion of piston rod 222, this embodiment proposes that one end of each piston rod 222 is arranged in the corresponding piston cylinder 212, and an elastic member 23 is connected between each piston rod 222 and the corresponding piston cylinder 212; the other end of each piston rod 222 is transmission connected to the main body 223 of the washing rack; specifically, the elastic member 23 can be arranged in the piston cylinder 212, the elastic member 23 is sleeved on the piston rod 222, and one end of the elastic member 23 is connected to the piston rod 222, and the other end of the elastic member 23 is connected to the inner side wall of the piston cylinder 212; or, the elastic member 23 can also be arranged outside the piston cylinder 212, the elastic member 23 is sleeved on the piston rod 222, and one end of the elastic member 23 is connected to the piston rod 222, and the other end of the elastic member 23 is connected to the outer side wall of the piston cylinder 212; preferably, the elastic member 23 is a spring.

[0087] like Figure 3 As shown, the spray washing mechanism 2 further includes a cam assembly, which includes a coaxially arranged active cam 24 and a driven cam 25, one end of the active cam 24 is transmission-connected to one end of the driven cam 25, and the other end of the driven cam 25 is fixedly connected to the main body 223 of the washing rack;

[0088] When the active cam 24 rotates, the piston rod 222 can reciprocate along the corresponding piston cylinder 212 under the action of the driven cam 25 and the elastic member 23;

[0089] Specifically, if Figure 4a and Figure 4bAs shown, the driving cam 24 is formed with a first convex-concave portion 241 at one end that cooperates with the driven cam 25, and the driven cam 25 is formed with a second convex-concave portion 251 at one end that cooperates with the driving cam 24, and the first convex-concave portion 241 and the second convex-concave portion 251 can cooperate with each other; the driving cam 24 and the driven cam 25 have a first cooperation state and a second cooperation state; when the driving cam 24 and the driven cam 25 are in the first cooperation state, the convex surface of the first convex-concave portion 241 cooperates with the convex surface of the second convex-concave portion 251; when the driving cam 24 and the driven cam 25 are in the second cooperation state, the convex surface of the first convex-concave portion 241 cooperates with the concave surface of the second convex-concave portion 251, and the concave surface of the first convex-concave portion 241 cooperates with the convex surface of the second convex-concave portion 251;

[0090] When the active cam 24 and the driven cam 25 are switched from the first engagement state to the second engagement state, the active cam 24 and the driven cam 25 approach each other, and the driven cam 25 and the washing rack 22 move toward a side away from the support frame 11;

[0091] When the active cam 24 and the driven cam 25 are switched from the second matching state to the first matching state, the active cam 24 and the driven cam 25 move away from each other, and the driven cam 25 drives the washing rack 22 to move toward the side close to the support frame 11;

[0092] Furthermore, each of the first convex-concave portion 241 and the second convex-concave portion 251 is provided with at least one group; wherein, each group of the first convex-concave portion 241 corresponds to a group of the second convex-concave portion 251; when the active cam 24 rotates, so that the active cam 24 and the driven cam 25 gradually switch from the second matching state to the first matching state, the convex surface of the first convex-concave portion 241 gradually matches the convex surface of the second convex-concave portion 251, and the driven cam 25 moves upward along the axis of the driven cam 25, and the piston rod 222 approaches the corresponding first profiling structure 111 along the corresponding piston cylinder 212, and the corresponding elastic member 23 is compressed to store energy. The driving cam 24 and the driven cam 25 are in the first matching state; the driving cam 24 continues to rotate, the elastic member 23 releases energy and drives the corresponding piston rod 222 along the corresponding piston cylinder 212 away from the corresponding first profiling structure 111, and then the driven cam 25 moves downward along the axis of the driven cam 25, the convex surface of the first convex-concave portion 241 gradually matches with the concave surface of the second convex-concave portion 251, and the concave surface of the first convex-concave portion 241 gradually matches with the convex surface of the second convex-concave portion 251, and the driving cam 24 and the driven cam 25 gradually switch from the first matching state to the second matching state.

[0093] In order to improve the smoothness of the transmission of the active cam 24 and the driven cam 25, in this embodiment, the convex surface of the first convex-concave portion 241 smoothly transitions with the concave surface of the first convex-concave portion 241, and the convex surface of the second convex-concave portion 251 smoothly transitions with the concave surface of the second convex-concave portion 251.

[0094] In response to the problem of unstable movement of the driven cam 25, this embodiment proposes that the driven cam 25 is formed with a first guide structure 252, and the end of the active cam 24 that cooperates with the driven cam 25 is formed with a second guide structure 242; the first guide structure 252 and the second guide structure 242 cooperate so that the driven cam 25 can reciprocate along the axis of the driven cam 25 relative to the active cam 24; specifically, the first guide structure 252 is a guide hole, and the axis of the guide hole is consistent with the axis of the driven cam 25; the second guide structure 242 is a guide column, and the axis of the guide column is consistent with the axis of the active cam 24; one end of the guide column is connected to the active cam 24, and the other end of the guide column is arranged in the guide hole; when the driven cam 25 slides relative to the active cam 24, the guide hole cooperates with the guide column.

[0095] In order to solve the problem that washing water cannot wash the outer wall of the bra, this embodiment proposes that the underwear washing device also includes a rotating mechanism 3, which includes a drain bucket 31 and a reinforcing plate 32. The drain bucket 31 is arranged around the outer periphery of the supporting mechanism 1, and the drain bucket 31 and the mounting frame 13 can be linked together; specifically, the mounting frame 13 is arranged on the bottom wall of the drain bucket 31 and is located on the inner side of 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 main The axis of the movable cam 24 is consistent; a drain hole 311 is formed on the side wall of the drain bucket 31, and the washing water on the outside of the drain bucket 31 can enter the inside of the drain bucket 31 through the drain hole 311; a first rib 312 is provided on the inside of the side wall of the drain bucket 31, and the first rib 312 protrudes toward the inside of the drain bucket 31 and is arranged close to the support cover 12; when the drain bucket 31 rotates, the first rib 312 can push the washing water inside the drain bucket 31 toward the support cover 12, thereby washing the outer wall of the bra;

[0096] The 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 strengthen 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 31. 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 wavy structure. The first rib 312 and the second rib 321 form a torrent flushing effect, which can improve the washing effect.

[0097] According to the different states of the drain bucket 31, the underwear washing device has multiple washing modes:

[0098] When the drain bucket 31 rotates, the drain bucket 31 can drive the support mechanism 1 and the reinforcing plate 32 to rotate synchronously, so that the rotating mechanism 3 applies a rotational centrifugal force to the bras in the clamping space, which can be rotated to wash the bras or rotated to dehydrate the bras; when the drain bucket 31 does not rotate, the active cam 24 rotates, and then the driven cam 25 and the washing rack 22 reciprocate along the axis of the driven cam 25, and the piston rod 222 reciprocates along the corresponding piston cylinder 212, so that the washing water in the spray chamber 211 applies a spraying force to the bras in the clamping space, which can spray and wash the bras;

[0099] Specifically, the drain bucket 31 is enclosed to form a washing space to achieve washing and dehydration of the bra. At the same time, the washing space can also prevent the shoulder straps on the bra from being entangled with the first ribs 312.

[0100] To solve the problem that spray washing, spin washing or dehydration cannot be selected according to actual conditions, this embodiment proposes that the reinforcing plate 32 forms a limiting hole 322, and the limiting hole 322 is rotatably provided with an active cam 24;

[0101] The underwear washing device further includes a drive mechanism 4, which includes a clutch 41. The clutch output shaft 411 can be selectively connected to the active cam 24 or the drain bucket 31. Specifically, when the clutch output shaft 411 is connected to the active cam 24, the clutch output shaft 411 can drive the active cam 24 to rotate, thereby causing the piston rod 222 to reciprocate along the corresponding piston cylinder 212, causing the washing water in the corresponding spray chamber 211 to spray and wash the bras in the clamping space.

[0102] When the output shaft 411 of the clutch is driven and connected to the drain bucket 31, the output shaft 411 of the clutch can drive the rotating mechanism 3 and the supporting mechanism 1 to rotate synchronously, so that the rotating mechanism 3 can perform a rotary washing or dehydration effect on the bra in the clamping space; the rotary washing is combined with the spray washing to achieve a comprehensive and thorough washing of the bra; the rotation dehydrates the bra, avoiding deformation of the bra during the dehydration process.

[0103] To sum up, the support cover 12, support frame 11, mounting frame 13, washing rack 22, cam assembly, reinforcement plate 32, drain bucket 31 and driving mechanism 4 are arranged in sequence from top to bottom; when the rotating mechanism 3 and the supporting mechanism 1 rotate synchronously, the bra can be rotated for washing or the bra can be dehydrated; when the active cam 24 rotates, the washing rack 22 reciprocates relative to the mounting frame 13, and the piston rod 222 reciprocates in the corresponding piston cylinder 212, so that the washing water in the spray chamber 211 can be sprayed to wash the bra.
