[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely embodiments of one part of the present invention, and not embodiments of the entire invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] To address the technical problem of the lack of a dedicated underwear washing device in related technologies, this invention provides an underwear washing device.

[0032] like Figure 1 As shown, it includes: a cylindrical body 10; a rotating mechanism, which is a cylindrical structure and rotatably disposed inside the cylindrical body 10; a support mechanism 30, disposed inside the rotating mechanism and fixed together with the rotating mechanism in a linkage manner; the support mechanism 30 has a clamping space 1 for clamping the underwear; a driving mechanism, which provides the driving force required by the rotating mechanism; the support mechanism 30 is provided with at least one first through hole 300 communicating with the clamping space 1; and / or the rotating mechanism 20 is provided with at least one second through hole 211 communicating with the interior of the cylindrical body 10.

[0033] In this way, the support mechanism 30 can be used to fix the underwear, and the rotating mechanism 20 can drive the support mechanism 30 to rotate together, so as to wash or dehydrate the underwear. The support mechanism 30 can prevent the underwear from deforming during the washing process. Water can come into contact with the underwear through the first through hole 300 and / or the second through hole 211 to wash the underwear; water on the underwear can also be discharged through the first through hole 300 and / or the second through hole 211 to dehydrate the underwear.

[0034] Optionally, the support mechanism 30 can be designed as a hollow structure, with its hollow holes forming a first through hole 300. The second through hole 211 of the rotating mechanism can be formed by a through hole opened on the wall of the cylindrical structure that connects the inside and outside of the cylinder.

[0035] Optionally, protruding ribs 200 are provided on the side walls and / or bottom walls of the rotating mechanism 20. In this way, the protruding ribs 200 can be used to form a jet stream, thereby creating a three-dimensional rinsing effect, which is beneficial to improving the cleaning effect of underwear.

[0036] Alternatively, the ribs 200 can be arranged in an arc shape, strip shape, or wave shape. This will create a better effect in generating torrents.

[0037] In one alternative embodiment of this application, a plurality of protruding ribs 200 arranged in a wave-like pattern are spaced apart circumferentially around the rotating mechanism 20.

[0038] In one optional embodiment of this application, protruding ribs 200 are provided on both the side wall and the bottom wall of the rotating mechanism 20. The protruding ribs 200 on the side wall of the rotating mechanism 20 are positioned closer to the top mechanism of the rotating mechanism 20 than the bottom mechanism.

[0039] Optionally, the side wall of the rotating mechanism 20 is provided with a protruding first rib 212 and / or the bottom wall of the rotating mechanism 20 is provided with a protruding second rib 221.

[0040] Optionally, the rotating mechanism 20 includes: a drain bucket 21, the side wall of the drain bucket 21 having at least one second through hole 211, and the side wall of the drain bucket 21 also having at least one protruding first rib 212.

[0041] Optionally, the rotating mechanism 20 includes a reinforcing plate 22, which is disposed at the bottom of the drain bucket 21, and the reinforcing plate 22 is provided with at least one protruding second rib 221.

[0042] Optionally, the first rib 212 and / or the second rib 221 may be arranged in an arc shape, a strip shape, or a wave shape. The shape and number of the first rib 212 and / or the second rib 221 can be selected according to actual needs.

[0043] Specifically, such as Figures 2 to 4 The embodiment shown includes a rotating mechanism 20 comprising: a drain bucket 21, the side wall of which is provided with at least one second through hole 211 and at least one protruding first rib 212; and a reinforcing plate 22, which is disposed at the bottom of the drain bucket 21 and is provided with at least one protruding second rib 221.

[0044] In this way, the wall thickness of the drain bucket 21 can be set to be relatively thin, and the reinforcing plate 22 can be set at the bottom mechanism of the drain bucket 21 to improve the overall strength of the rotating mechanism 20.

[0045] like Figure 4 As shown, the first rib 212 on the drain bucket 21 is wavy. The first rib 212 can also be called a wave blade.

[0046] like Figure 4 As shown, the first rib 212 is located near the top of the drain bucket 21, so that it can better cooperate with the second rib 221 on the reinforcing plate 22 to form a torrent, thereby creating a three-dimensional rinsing effect.

[0047] Optionally, the underwear includes a bra; a receiving space 2 is formed between the support mechanism 30 and the rotating mechanism 20 for accommodating the bra shoulder straps and back straps.

[0048] Furthermore, the support mechanism 30 includes: a support frame 31 having two first protrusions 310 in the shape of bra cups; and a support cover 32 having two second protrusions 320 in the shape of bra cups. The support cover 32 covers the support frame 31. The two second protrusions 320 are arranged one-to-one with the two first protrusions 310 and protrude in the same direction. A clamping space 1 for clamping the bra is formed between the support frame 31 and the support cover 32. The two cups of the bra are clamped between the two first protrusions and the two second protrusions.

[0049] In this way, the bra is clamped between the support frame 31 and the support cover 32, and the bra cups are fixed by the first protrusion structure 310 and the second protrusion structure 320, which can prevent the bra from deforming while clamping it.

[0050] It should also be noted that the "fixation" of clothing referred to in this application does not mean that it is completely immobile. As those skilled in the art will understand, some movement is permissible during the compression process of the compression mechanism, otherwise it would cause damage to the clothing.

[0051] like Figure 2 As shown, a clamping space 1 for clamping the bra cups is formed between the first protrusion structure 310 and the second protrusion structure 320; a receiving space 2 for accommodating the bra shoulder straps and back straps is formed between the support mechanism 30 and the rotation mechanism 20.

[0052] This provides better support, making the bra cups less prone to deformation, as well as the bra straps and back straps, and less likely to become tangled.

[0053] In one optional embodiment of this application, the inner diameter of the rotating mechanism 20 is D1; ​​the outer diameter of the support mechanism 30 is D2; wherein D1 / D2 ≥ 1.3 or D1 / D2 ≥ 1.5. This provides a larger accommodating space 2, preventing the shoulder strap or back strap from getting stuck on the support mechanism 30.

[0054] like Figure 3 As shown, the support frame 31 includes: a mounting frame 311, which is connected to the rotating mechanism 20, and has two clearance spaces 3; the two clearance spaces 3 are provided in a one-to-one correspondence with two first protrusion structures 310; an intermediate layer, which has a flexible structure 312, and is disposed on the mounting frame 311 with the flexible structure 312 covering the outlet of the clearance space 3; and a support cover 32 covering the flexible structure 312, with a clamping space 1 formed between the flexible structure 312 and the support cover 32.

[0055] In this way, the flexible structure 312 can prevent damage to the underwear, and the underwear is sandwiched between the flexible structure 312 and the support cover 32.

[0056] In one alternative embodiment of this application, the intermediate layer may also be omitted.

[0057] The clamping space 1 between the flexible structure 312 and the support cover 32 can accommodate underwear of different sizes.

[0058] exist Figure 2 In the illustrated embodiment, the support mechanism 30 includes a mounting frame 311, and the rotating mechanism 20 includes a drain bucket 21. The outer diameter of the mounting frame 311 is D2, and the inner diameter of the drain bucket 21 is D1, where D1 / D2 ≥ 1.3 or D1 / D2 ≥ 1.5. This provides a larger accommodating space 2, preventing shoulder straps or back straps from getting stuck on the mounting frame 311.

[0059] like Figure 3 As shown, the lingerie washing device also includes: a squeezing mechanism 40, which has two third protrusions 41 in the shape of bra cups, forming two squeezing ends. These two squeezing ends correspond one-to-one with two clearance spaces 3. The squeezing ends are used to squeeze the first protrusions 310 of the flexible structure 312 through the clearance spaces 3, thereby squeezing the bra located within the clamping space 1 through the flexible structure 312; and a driving mechanism 50, which provides power to the squeezing mechanism 40 and the rotating mechanism 20. Thus, the squeezing mechanism 40 can be used to perform squeezing washing and squeezing dehydration on the lingerie.

[0060] like Figure 3 As shown, the drive mechanism 50 includes: a cam assembly 51, comprising a rotating member 511 and a connecting member 512, the connecting member 512 being connected to the extrusion mechanism 40; the mating surfaces of the rotating member 511 and the connecting member 512 having a concave-convex structure; the connecting member 512 driving the extrusion mechanism 40 to move under the pushing action of the rotating member 511; a clutch 52, connected to the cylinder 10, the clutch 52 being selectively engaged with the cam assembly 51 or the rotating mechanism 20; and a rotary motor, the rotary motor being driven by the cam assembly 51 or the rotating mechanism 20 via the clutch 52. In this way, the cam assembly 51 converts rotation into movement; only one rotary motor is needed, and by switching the state of the clutch 52, the extrusion mechanism 40 can be driven to move or the rotating mechanism 20 can be driven to rotate.

[0061] Optionally, such as Figure 7 and Figure 8As shown, the support cover 32 includes a cover body 321, which has two second protrusions 320. Each of the two second protrusions 320 has multiple first through holes 300 arranged in an elongated shape, forming a hollow structure. The two second protrusions 320 have a large arc surface, which can be used for underwear of different sizes. The outer periphery of the second protrusions 320 also has multiple first through holes 300 arranged in a circle, which is conducive to water entering or exiting the clamping space 1.

[0062] exist Figure 9 In the optional embodiment shown, the two first protrusions 310 of the flexible structure 312 of the support frame 31 are provided with a plurality of circular first through holes 300, which facilitates water to enter the inside of the underwear or to drain water through the flexible structure 312.

[0063] exist Figure 10 In the alternative embodiment shown, the two first protrusions 310 of the flexible structure 312 of the support frame 31 are not provided with first through holes 300.

[0064] The location, shape, and number of the first through hole 300 can be selected according to actual needs.

[0065] exist Figure 11 In the optional embodiment shown, the third protrusion structure 41 of the extrusion mechanism 40 is provided with at least one third through hole 400, so that water can easily enter or exit through the third through hole 400 when the extrusion mechanism 40 extrudes the flexible structure 312.

[0066] Optionally, the support cover 32 is hinged to the support frame 31 so that the support cover 32 can be flipped relative to the support frame 31, and the support cover 32 has an open position and a closed position; and / or

[0067] One of the support frame 31 and the support cover 32 is provided with a first snap-fit ​​structure 301 and the other is provided with a second snap-fit ​​structure 302, so that the support cover 32 is snapped into the support frame 31; and / or

[0068] One of the support frame 31 and the support cover 32 is provided with a positioning post 303, and the other is provided with a positioning hole 304.

[0069] exist Figure 3 , Figures 5 to 8 In the optional embodiment shown, the mounting bracket 311 is provided with a positioning post 303 and a first snap-fit ​​structure 301, the cover 321 is provided with a positioning hole 304 and a second snap-fit ​​structure 302, and the flexible structure 312 is connected to the mounting bracket 311 by screws.

[0070] like Figure 2As shown, clutch 52 is fixed to the drum 10. The shaft of clutch 52 passes through the drum 10 and connects to the drain tub 21 and cam assembly 51 respectively. Reinforcing plate 22 is fixed to the bottom mechanism of drain tub 21. The arc-shaped mounting bracket 311 is also fixed to the bottom mechanism of drain tub 21. Squeezing mechanism 40 is connected above cam assembly 51. Before washing, the underwear is placed on the support mechanism 30 and fixed in place, and then washing begins. Clutch 52 drives cam assembly 51, drain tub 21 remains fixed, and cam assembly 51 starts to rotate, driving squeezing mechanism 40 to squeeze the underwear up and down. After squeezing and washing for a period of time, clutch 52 switches to another state, driving drain tub 21 to rotate. During the rotation of drain tub 21, the ribs on the side wall and the reinforcing plate at the bottom of the tub are driven to form a turbulent flow, creating a three-dimensional washing effect. Throughout the washing process, the underwear shoulder straps and back straps remain between mounting bracket 311 and drain tub 21, preventing tangling and wear.

[0071] The lingerie washing device provided in this application can use the support mechanism 30 to provide support for the lingerie, reducing the problem of severe deformation of the lingerie during daily washing; the drain bucket 21 provides space for the shoulder straps and back straps of the lingerie, preventing the shoulder straps and back straps of the lingerie from getting tangled with the wave blades during the washing process, and can form a turbulent rinsing effect through the ribs, which can solve the problem of easy deformation of lingerie during washing, and solve the problem of low washing ratio and difficulty in rinsing caused by restricting the movement of lingerie.

[0072] This invention provides a bra tub structure with an arc-shaped frame supporting a drain tub. A reinforcing plate with two ribs is installed below the drain tub, and four corrugated ribs (leaves) are evenly distributed around the tub wall. During washing, as the drain tub rotates, the reinforcing plate and the ribs create a powerful jet of water to rinse the bra. Shoulder straps and back straps are placed within the drain tub to prevent tangling. This, combined with the operation of the arc-shaped frame, achieves the goal of cleaning the bra. During rinsing, the powerful jet of water carried by the ribs thoroughly rinses the bra and removes foam. The drain tub wall is perforated to drain water during spin-drying, ensuring the internal structure of the machine remains dry and reducing bacterial growth.
