Detailed Implementation

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0053] Currently available washing machines are not specifically designed for washing underwear and other intimate apparel. Traditional washing methods often result in underwear deforming during washing. This invention provides a bra washing mechanism. During washing, a support frame cradles the bra, and a support cover secures the bra cradle, preventing deformation during washing and effectively protecting the underwear.

[0054] The following is in conjunction with the appendix Figure 1-11 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0055] Example like Figure 1 As shown, this embodiment proposes a bra washing mechanism, which includes: Fixing device for securing the bra; A compression device used to apply pressure to a bra. The rotating device can be linked with the fixing device to drive the fixing device to rotate together and thus rotate the bra. A drive unit for optional connection to the extrusion and rotation devices.

[0056] The bra washing mechanism in this embodiment of the invention can fix the bra in place during washing, preventing deformation and effectively protecting it. Simultaneously, the drive device can be selectively connected to a squeezing device or a rotating device, thereby changing the washing operation of the bra washing mechanism. When the drive device is selected to be connected to the squeezing device, a squeezing washing operation is performed; when the drive device is selected to be connected to the rotating device, a dehydration operation is performed.

[0057] like Figure 2 As shown, the fixing device includes a support frame 1 and a support cover 2, and a clamping space for limiting the bra is formed between the support frame 1 and the support cover 2: In the bra washing mechanism of this invention, the support frame 1 and the support cover 2 can clamp and limit the bra during washing, and can prevent the bra from deforming during washing and effectively protect the bra.

[0058] 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.

[0059] In any of the above embodiments, the support frame 1 has two first protrusion structures 11 adapted to the shape of the bra cup; The support cover 2 has two second protruding structures 21 that are adapted to the shape of the bra cup; The support cover 2 is placed on the support frame 1, and the two first protrusion structures 11 and the two second protrusion structures 21 are arranged in a one-to-one correspondence and have the same protrusion direction; When washing the bra, the two first protrusions 11 are used to fit the inner contour surface of the bra cup as a carrier for the bra, and the two second protrusions 21 are used to fit the outer contour surface of the bra cup to clamp and limit the bra placed on the support frame 1.

[0060] In this embodiment of the invention, by arranging the support frame 1 and the support cover 2 according to the shape of the bra, the support frame 1 and the support cover 2 can effectively conform to both sides of the bra during washing, thereby improving the bra's fixation effect and further reducing the deformation of the underwear during washing. Simultaneously, since the underwear is placed between the support frame 1 and the support cover 2 during washing, the compression device does not directly act on the bra surface, thus effectively protecting the bra and reducing wear and tear on the garment.

[0061] In any of the above embodiments, such as Figure 2As shown, the main outlines of the support frame 1 and the support cover 2 are both arc-shaped components. It is worth noting that the arc shape in this embodiment is not an arc shape in the strictest sense. The shape in some minor details can also be other shapes that are different from the arc shape, as long as the overall shape roughly presents an arc.

[0062] The first protruding structure 11 protrudes from the main outline of the support frame 1 and has a first outer convex surface and a first inner convex surface. The second protruding structure 21 protrudes from the main outline of the support cover 2 and has a second outer convex surface and a second inner convex surface. The first convex surface of the first protrusion structure 11 is used to adapt to the inner contour surface of the bra cup, and the second convex surface of the second protrusion structure 21 is used to adapt to the outer contour surface of the bra cup.

[0063] In this embodiment, by setting the support frame 1 and the support cover 2 to be arc-shaped, the bra can fit better when placed between the support frame 1 and the support cover 2.

[0064] When washing the bra, the first outer convex surface of the first protrusion structure 11 is adapted to the inner contour surface of the bra so that the inner contour surface of the bra is completely fitted onto the support frame 1. The second inner convex surface of the second protrusion structure 21 is adapted to the outer contour surface of the bra so that when fixing the bra, the support cover 2 can be completely fitted to the outer contour surface of the bra, and the support frame 1 can be completely fitted to the inner contour surface of the bra. This achieves the effect of maximizing the squeezing coverage area of ​​the squeezing device during the washing process, thereby improving the fixing effect and washing effect of the bra and preventing the bra from deforming.

[0065] like Figure 2 As shown, the two first protruding structures 11 are symmetrically arranged about the center of symmetry of the central axis of the support frame 1. The two second protruding structures 21 are symmetrically arranged about the center of symmetry of the central axis of the support cover 2.

[0066] In any of the above embodiments, the support cover 2 is rotatably disposed, wherein the support cover 2 has a first state and a second state when it rotates; When the support cover 2 is in the first state, the support cover 2 clamps and limits the bra; When the support cover 2 is in the second state, the support cover 2 removes its clamping limit on the bra, and the bra can be put on and taken off.

[0067] In this embodiment of the invention, by rotating the support cover 2, it is convenient to clamp and limit the bra, making it easier for the user to operate and use.

[0068] In any of the above embodiments, the support frame 1 and / or the support cover 2 are provided with a perforated structure, so that when washing the bra, the washing water can pass through the perforated structure and act on the bra. Preferably, both the support frame 1 and the support cover 2 are provided with perforated structures, so that the washing water can pass through the perforated structures and act on the outer and inner contour surfaces of the bra.

[0069] In any of the above embodiments, such as Figure 1 As shown, the placement structure also includes a fixing frame 3 whose position can be fixed, wherein the fixing frame 3 serves as the mounting carrier for the support frame 1; When the support frame 1 is installed on the fixed frame 3, the support frame 1 and the fixed frame 3 are fitted together. This improves the stability of the support frame 1 when it is installed on the fixed frame 3, and prevents the support frame 1 from shifting relative to the fixed frame 3 when washing bras, thereby preventing the bras from shifting during washing and improving the washing and fixing effect of underwear.

[0070] In any of the above embodiments, such as Figure 2 As shown, the fixing frame 3 is an arc-shaped structure. When the support frame 1 is fitted to the fixing frame 3, the outer arc surface of the fixing frame 3 fits against the inner arc surface of the support frame 1. By making both the fixing frame 3 and the support frame 1 arc-shaped structures, it is easier to connect the two.

[0071] In any of the above embodiments, the aforementioned support cover 2 is rotatably mounted on the support frame 1 or the fixed frame 3. By rotatably mounting the support cover 2 on the support frame 1 or the fixed frame 3, it is convenient to take out and put in the bra.

[0072] It should be noted that the support cover 2 in the embodiments of the present invention can be an integral structure or a separate structure. For example Figure 1 As shown, when the support cover 2 is a one-piece structure, simply hinge the left or right end of the support cover 2 to the support frame 1 or the fixing frame 3. Correspondingly, the right or left end of the support cover 2 is fixed to the support frame 1 and the fixing frame 3. When the support cover 2 is a split structure, both the left and right ends of the support cover 2 need to be hinged to the support frame 1 or the fixing frame 3. In this case, the support cover 2 is composed of two separate arc-shaped frames. When the support cover 2 needs to be closed, the two split contour frames meet and are fixed in the middle of the support cover 2. It should also be noted that when fixing the support cover 2, the fixing method can be any locking method with a locking effect, such as snap-locking or bolt locking.

[0073] During the washing process of the bra, the squeezing device will squeeze the support frame 1 by moving up and down. Since the fixed frame 3 is located at the lower end of the support frame 1, when the washing rack 5 squeezes the support frame 1 by moving up and down, it will squeeze the fixed frame 3 first, which will affect the washing effect of the bra.

[0074] In order to improve the washing effect of the bra, the fixing frame 3 in this embodiment has two clearance holes 31. When the support frame 1 is set on the fixing frame 3, the two clearance holes 31 are opposite to the two first inner convex surfaces of the two first protrusion structures.

[0075] In any of the above embodiments, such as Figures 3-6 As shown, the aforementioned squeezing device includes a washing rack 5, which can be driven to apply a washing force to the bra sandwiched between the support frame 1 and the support cover 2.

[0076] The washing rack 5 has two third protrusions 52, which are arranged one-to-one with two clearance holes 31. The two third protrusions 52 form two squeezing ends. The squeezing ends of the washing rack 5 are movably or retractably arranged below the support frame 1. The two third protrusions 52 can be driven to pass through the two clearance holes 31 to squeeze the support frame 1 and squeeze the bra sandwiched between the support frame 1 and the support cover 2.

[0077] When washing bras, the washing rack 5 passes through the clearance hole 31 and acts on the support frame 1. Repeatedly squeezing the support frame 1 then achieves the squeezing and washing of the bras. The width of the clearance hole 31 is greater than the width of the washing rack 5, thus preventing interference between the washing rack 5 and the support frame 1 during reciprocating motion. This improves both the washing effect and the stability of the bra washing mechanism.

[0078] Specifically, the washing rack 5 can be driven to reciprocate to continuously squeeze the bra clamped between the support frame 1 and the support cover 2 through the squeezing end of the washing rack 5. like Figure 5 As shown, in order to improve the stability of the washing rack 5 when it is reciprocating, a limiting structure 32 is provided on the fixed frame 3 in this embodiment, and the washing rack 5 and the limiting structure 32 slide in the direction of movement of the washing rack 5.

[0079] In any of the above embodiments, in order to avoid damage to the bra when the washing rack 5 is squeezed and washed, the support frame 1 is partially or entirely designed to be flexible; and / or the washing rack 5 is partially or entirely designed to be flexible. When part of the support frame 1 is designed to be flexible, the first protrusion structure of the support frame 1 is designed to be flexible. When part of the washing rack 5 is designed to be flexible, the squeezing end of the washing rack 5 is designed to be flexible.

[0080] In any of the above embodiments, such as Figure 3 and Figure 4 As shown, the washing rack 5 has a main body 51 and two third protrusions 52 adapted to the shape of the bra cup, wherein the two third protrusions 52 are formed on the main body 51. When the washing rack 5 is driven to reciprocate, the two third protrusions 52 on the washing rack 5 can squeeze the two first inner protrusions of the support frame 1 and squeeze the bra cup sandwiched between the support frame 1 and the support cover 2.

[0081] like Figure 1 As shown, the washing rack 5 can be driven to reciprocate along a preset trajectory. When the washing rack 5 reciprocates along the preset trajectory, the squeezing end of the washing rack 5 applies a squeezing and washing force to the bra. That is, in Figure 1 In the example, the washing rack 5 can be driven to reciprocate up and down. Of course, in some alternative embodiments, the washing force exerted by the washing rack 5 on the bra is not limited to applying a washing force through reciprocating motion; it can also apply a squeezing washing force by directly rotating and squeezing. That is, in some alternative embodiments, the squeezing end of the washing rack 5 can be pressed into contact with the support frame 1, and the squeezing end of the washing rack 5 can be made rotatable. Thus, when the squeezing section of the washing rack 5 rotates, it can also achieve the squeezing washing effect on the bra. As long as the washing rack 5 can apply a squeezing washing force to the bra, it is acceptable. However, relatively speaking, in this embodiment, it is preferable to set the washing rack 5 in a reciprocating motion mode to apply a washing force to the bra.

[0082] It is worth noting that in this embodiment, the washing rack 5 at least partially passes through the clearance hole 31. This can be done by the detergent 5 reciprocating through the clearance hole 31, or by the washing rack 5 being partially or entirely within the clearance hole 31 at all times. The key is to ensure that the washing rack 5 can apply a washing force to the bra mounted on the support frame 1 during its reciprocating motion without interfering with the clearance hole 31. However, it is preferable to configure the squeezing end of the washing rack 5 to always be within the clearance hole 31, as this provides a better squeezing and washing effect.

[0083] In any of the above embodiments, in order to further improve the squeezing and washing effect on the bra, such as Figure 5 As shown, the main body 51 includes a base 511 and a piston rod 512 disposed on the base; A spray chamber 53 is formed on the third protrusion structure 52. One side of the spray chamber 53 is connected to one end of the piston sleeve 54, and the other side is open to the surface of the third protrusion structure 52. Specifically, multiple openings for spraying are formed on the surface of the third protrusion structure 52. The piston rod 512 is slidably fitted into the piston sleeve 54 through the other end of the piston sleeve 54; The piston rod 512 can be driven to slide back and forth along the piston sleeve 54, and the piston rod 512 can draw in and squeeze water flow when it slides back and forth along the piston sleeve 54.

[0084] When the piston rod 512 is driven to slide to one side of the spray chamber 53, the washing water outside the spray chamber 53 can be drawn into the spray chamber 53 for storage. When the piston rod 512 is driven to slide away from the spray chamber 53, the washing water drawn into the spray chamber 53 can be squeezed. The washing water can be sprayed onto the support frame 1 through multiple spray nozzles on the surface of the third protrusion structure 52 to wash the bra.

[0085] Specifically, such as Figure 5 As shown, there are two piston rods 512, which are symmetrically arranged with the central axis of the base 511 as the center of symmetry. Each of the two third protrusions 52 is provided with a spray chamber 53 and a piston sleeve 54, and the two piston rods 512 are correspondingly slidably sleeved in the piston sleeves 54 on the two third protrusions 52. Two piston rods 512 can be driven to reciprocate synchronously, and when the two piston rods 512 are driven to reciprocate synchronously, they drive two third protrusion structures 52 to reciprocate synchronously.

[0086] In this embodiment, by setting the two piston rods 512 to reciprocate synchronously, the two piston rods 512 can perform water suction and water spraying operations. At the same time, when the two piston rods 512 perform water suction and water spraying operations synchronously, they can drive the two third protrusion structures 52 to reciprocate synchronously, thereby performing a squeezing and washing operation on the two cups of the bra simultaneously. This ensures that the two cups of the bra maintain the same effect after washing, avoiding the problem that one cup of the bra has a better washing effect than the other, thus ensuring a more uniform washing effect when washing the bra.

[0087] More specifically, such as Figure 4 As shown, both piston rods 512 are rotatably connected to the base 511, and the two third protrusion structures 52 are connected by the first elastic element 55. The base 511 can be driven to reciprocate along the central axis of the base 511, that is, in Figure 5 In the example, the base 511 can be driven to reciprocate along the vertical direction, and the base 511 along the central axis direction Figure 1 When the piston rod 512 moves up and down towards one side of the bra, it can squeeze the water flow in the spray chamber 53 to spray the water out. When the base 511 moves along the central axis away from the bra, the piston rod 512 can draw in the water flow to suck the water flow into the spray chamber 53.

[0088] The advantage of this embodiment, which rotatably connects the two piston rods 512 to the base 511 and connects the two third protrusion structures 52 through the second elastic member 55, is that in this embodiment, the two piston rods 512 and the two third protrusion structures 52 can be driven to move synchronously through a single transmission mechanism, thus saving production costs.

[0089] Of course, in some alternative embodiments, the first elastic element 55 can be omitted and the rotation between the piston rod 512 and the base 511 can be eliminated. Two power transmission components can be used to drive the two piston rods 512 respectively, achieving synchronous movement of the two piston rods 512. However, relatively speaking, it is preferable to arrange the piston rods 512 and the two third protrusion structures 52 according to the above-described arrangement, which saves production costs and provides better washing results.

[0090] In any of the above embodiments, such as Figure 4 As shown, the washing assembly also includes a second elastic element 56 disposed in the piston sleeve 54. The second elastic element 56 is configured to automatically reset the base 511 after the base 511 moves upward along the central axis. In this embodiment, by providing a second elastic element in the piston sleeve 54, when the transmission mechanism transmits power to the piston rod 512, power only needs to be transmitted in one direction, that is, in Figure 3 In this example, the cam drive mechanism only needs to transmit upward force to the piston rod 512, while the downward force on the piston rod 512 is provided by the second elastic element 56. This also ensures the reciprocating motion of the piston rod 512.

[0091] Preferably, the second elastic element 56 mentioned above includes a spring disposed in the piston sleeve 54, wherein one end of the spring is connected to the inner wall of the piston sleeve 54 and the other end abuts against or connects to the piston rod 512. By setting the second elastic element 56 as a spring, the space occupied by the second elastic element 56 when disposed in the piston sleeve 54 can be reduced, thereby avoiding affecting the water absorption and spraying effect of the spray chamber 53.

[0092] In any of the above embodiments, such as Figure 3 As shown, the aforementioned extrusion device also includes a transmission unit, which includes a cam transmission mechanism 6, and the cam transmission mechanism 6 is connected to the bra washing mechanism. The cam drive mechanism 6 can be driven; when the cam drive mechanism 6 is driven, it can drive the washing rack 5 to squeeze and wash the bra sandwiched between the support frame 1 and the support cover 2. This allows the washing machine to have different washing modes when washing clothes.

[0093] In any of the above embodiments, such as Figure 6As shown, the cam transmission mechanism 6 includes a first cam 61 and a second cam 62; One end of the first cam 61 is connected to the washing rack 5, and the other end is engaged with the second cam 62. The second cam 62 can be driven to rotate, and when the second cam 62 rotates, it drives the first cam 61 to reciprocate along the central axis of the first cam 61.

[0094] Specifically, the first cam 61 has a first convex-concave portion 611 at one end that mates with the second cam 62, and the second cam 62 has a second convex-concave portion 621 at one end that mates with the first cam 61. The first convex-concave portion 611 and the second convex-concave portion 621 can be convex-concavely engaged. The first cam 61 and the second cam 62 have a first mating state and a second mating state that cooperate with each other; When the first cam 61 and the second cam 62 are in the first engagement state, the convex surface of the first convex-concave portion 611 engages with the convex surface of the second convex-concave portion 621. When the first cam 61 and the second cam 62 are in the second engagement state, the convex surface of the first convex-concave portion 611 engages with the concave surface of the second convex-concave portion 621, and the concave surface of the first convex-concave portion 611 engages with the convex surface of the second convex-concave portion 621. When the first cam 61 and the second cam 62 switch from the first engagement state to the second engagement state, the first cam 61 and the second cam 62 move closer to each other, causing the washing rack 5 to move away from the bra (the spring in the piston sleeve and the weight of the first cam 61 itself give the first cam 61 a downward force to make it engage with the second cam 62). When the first cam 61 and the second cam 62 switch from the second engagement state to the first engagement state, the first cam 61 and the second cam 62 move away from each other. The first cam 61 moves upward away from the second cam 62, and the upward movement of the first cam 61 drives the washing rack 5 to move towards the side closer to the bra.

[0095] More specifically, at least one set of the first convex and concave portion 611 and the second convex and concave portion 621 are provided; Each set of first convex and concave portions 611 corresponds to a set of second convex and concave portions 621.

[0096] Furthermore, in order to improve the smoothness of the transmission between the first cam 61 and the second cam 62, the convex and concave surfaces of the first convex and concave portion 611 and the second convex and concave portion 621 in this embodiment are smoothly transitioned.

[0097] In any of the above embodiments, the bra washing mechanism further includes a pressure sensor for detecting the stress on the garment during the garment processing.

[0098] Specifically, the pressure sensor is located between the compression device and the fixing device, and is used to detect the force value of the bra within the fixing device.

[0099] More specifically, a pressure sensor is installed between each of the two third protrusions 52 of the washing rack 5 and the two first protrusions 11 of the support frame 1.

[0100] In this embodiment of the invention, by setting a pressure sensor, the washing program of the bra washing mechanism can be controlled according to the force applied to the bra during the washing process, and / or the fixing device and / or rotating device and / or driving device can be controlled and / or adjusted, thereby preventing the bra from being damaged due to excessive force.

[0101] In any of the above embodiments, such as Figure 7 As shown, the rotating device mentioned above in this embodiment includes a cylindrical rotating part, which is arranged around the outer periphery of the fixing device and is fixed together with the fixing device in a linkage manner. The rotating part can be driven to rotate and drive the fixed device to rotate synchronously.

[0102] In this embodiment, by providing a rotating part that can be linked with the fixing device, the bra washing mechanism can have multiple washing modes during use. For example, when the rotating part is linked with the fixing device, the rotating part can drive the fixing device to rotate synchronously to perform the dehydration operation on the bra. When the rotating part is not driven to rotate, the washing rack 5 can be driven to reciprocate to squeeze and wash the bra, thereby performing the washing operation on the bra.

[0103] In any of the above embodiments, such as Figure 7 As shown, the rotating part includes a bottom wall and side walls provided on the bottom wall. The side walls of the rotating part are provided with protruding first ribs 42 and / or the bottom of the rotating part is provided with protruding second ribs 411; wherein the first ribs 42 and / or the second ribs 411 are arranged in an arc shape, a strip shape, or a wave shape. In this embodiment, by providing ribs on the side walls and / or bottom walls of the rotating part, the water flow agitation effect during washing can be improved.

[0104] Specifically, such as Figure 7As shown, the rotating part includes a drain tube 4 formed by the aforementioned bottom wall and side walls. The bottom of the drain tube 4 is circular, and the wall is annular. One end of the annular wall is formed on the outer periphery of the bottom, and the other end extends along the axial direction of the bottom. The side wall of the drain tube 4 is provided with at least one drain hole and at least one protruding first rib 42. The drain tube 4 is arranged around the outer periphery of the fixing frame 3 and is fixedly connected to the fixing frame 3. The drain tube 4 arranged around the outer periphery of the fixing frame 3 forms a clothing washing space between the drain tube 4, the support frame, and the support cover 2 to realize the washing and dehydration of the bra. At the same time, the clothing washing space formed can also prevent the bra straps from getting tangled with the first rib 42 on the drain tube 4.

[0105] More specifically, such as Figure 7 As shown, the rotating part also includes a reinforcing plate 41, which is disposed at the bottom of the drain tube 4. The reinforcing plate 41 has at least one protruding second rib 411. By providing a reinforcing plate 41 at the bottom of the drain tube 4, the strength of the drain tube 4 can be improved. By providing a second rib on the reinforcing plate 41, the stability of the drain tube 4 can be further enhanced, and a turbulent rinsing effect can be formed during washing.

[0106] In any of the above embodiments, when the aforementioned drive device is selected to transmit power to the rotating device, the rotating device can be driven to rotate and drive the fixed device to rotate synchronously. When the drive unit is selected to transmit power to the squeezing device, the squeezing device can drive the washing rack to reciprocate to squeeze the bra clamped between the support frame 1 and the support cover 2.

[0107] Specifically, when the drive unit is selected to transmit power to the extrusion device, the drive unit is powered by the cam transmission mechanism in the extrusion device. When the drive unit is selected to transmit power to the rotating device, the drive unit is connected to the drain cylinder in the rotating device.

[0108] In any of the above embodiments, as shown in 8, the aforementioned driving device includes: The clutch 7 and the clutch output shaft 71 provided at the output end of the clutch 7, the clutch output shaft 71 can be selectively connected to the cam drive mechanism or to the drain pipe via the clutch 7. When the clutch output shaft 71 is connected to the cam transmission mechanism, the clutch output shaft 71 drives the second cam 62 in the cam transmission mechanism to rotate, and through the first cam 61 cooperating with the second cam 62, drives the washing rack 5 to reciprocate, performing the squeezing and washing operation on the bra. When the clutch output shaft 71 is connected to the drain tube, the clutch output shaft 71 drives the drain tube and the fixing device to rotate synchronously, performing a dehydration operation on the bra or a rotation washing operation on ordinary clothes.

[0109] On the other hand, the embodiments of the present invention also provide a method such as 9- Figure 11 The washing machine shown includes the aforementioned bra washing mechanism, wherein the washing machine includes a washing drum 8, and the bra washing mechanism is rotatably disposed within the washing drum 8.

[0110] It is worth noting that when the above-mentioned bra washing mechanism is used in the washing machine, the clutch 7 mentioned above can be a clutch built into the bottom of the washing machine. When it is necessary to wash underwear, the power transmission mechanism 6 can be transmitted simply by connecting the cam transmission mechanism 6 to the clutch output shaft 71, without the need to set up a separate power source to drive the cam transmission mechanism 6.

[0111] In any of the above embodiments, such as Figure 11 As shown, when the power transmission assembly is connected to the clutch 7, the first cam 61 in the power transmission assembly is slidably sleeved on the clutch output shaft 71, and the second cam 62 is fixedly sleeved on the clutch output shaft 71. When the clutch output shaft 71 is connected to the cam transmission mechanism, the clutch output shaft 71 drives the second cam 62 to rotate. When the second cam 62 rotates, it cooperates with the first cam 61 to drive the first cam 61 to drive the washing rack 5 to move up and down reciprocally. It is worth noting that how the clutch 7 is connected to the drain drum 4 or to the cam is a technical means known to those skilled in the art, and will not be described in detail in this embodiment.

[0112] On the other hand, such as Figure 12 As shown, this embodiment also provides a bra washing control method, the bra washing mechanism including a rotation washing mode and a squeezing washing mode; the control method includes: Select and execute the squeeze washing mode and / or spin washing mode according to the preset conditions; And / or control the bra washing mechanism to alternately execute the squeezing washing mode and the rotating washing mode according to a preset rhythm; And / or control the bra washing mechanism to perform the squeezing washing mode and the rotating washing mode in a preset sequence.

[0113] Optionally, the control method further includes the following steps: controlling the bra washing mechanism to simultaneously execute a squeezing washing control program and a rotating washing control program within a third set time period.

[0114] Optionally, the bra washing mechanism is the bra washing mechanism described above; the squeezing washing control program includes: controlling the drive device of the bra washing mechanism to drive the squeezing end of the squeezing device of the bra washing mechanism to move or extend / retract; the rotation washing control program includes: controlling the drive device of the bra washing mechanism to drive the rotating device of the bra washing mechanism to rotate. Thus, by using the bra washing mechanism provided in this application to execute the control method provided in this application, both squeezing washing and rotation washing of the bra can be performed, thereby improving the cleaning effect of the bra.

[0115] Optionally, the bra washing mechanism is the bra washing mechanism described above; when the drive device of the bra washing mechanism includes a rotary motor, a clutch 7, and a cam transmission mechanism 6, the control method executes the following steps in the following order: S1. Begin washing; S2. Determine the working status of clutch 7; S3. When it is determined that the clutch 7 is in the first working state, control the bra washing mechanism to execute the squeezing washing control program and record the squeezing washing time. S4. Determine whether the squeezing and washing time is greater than or equal to the first set time. If yes, execute S5; otherwise, continue executing S3. S5. Control the clutch 7 to switch from the first working state to the second working state, control the bra washing mechanism to execute the rotation washing control program, and record the rotation washing time. S6. Determine whether the spinning wash time is greater than or equal to the second set time. If yes, proceed to S7; otherwise, continue to S5. S7. End washing.

[0116] This method of first squeezing and washing the bra, followed by centrifugal washing, helps improve the washing effect.

[0117] Optionally, the second set time is longer than the first set time, increasing the rotation washing time, which is more conducive to improving the washing effect of the bra.

[0118] Optionally, in Figure 12 In one specific embodiment shown, the washing process first enters the squeezing washing mode for 15 minutes, and then enters the rotating washing mode for 20 minutes, resulting in better washing effect and higher washing efficiency for the underwear.

[0119] In any of the above embodiments, such as Figure 13 and Figure 14 As shown, when the bra washing mechanism includes a pressure sensor, the washing control method further includes: Based on the stress conditions experienced during the bra washing process, the washing program of the bra washing mechanism is controlled, and / or the fixing device and / or rotating device and / or driving device are controlled and / or adjusted. In this way, when the stress on the bra is too high or too low, the bra washing mechanism can be adjusted to solve the problems of bra damage due to excessive stress or poor cleaning or dehydration due to insufficient stress. This improves the control precision of the bra washing mechanism and allows for control based on the stress conditions on the bra, thereby improving washing effect, washing efficiency, dehydration effect, and dehydration efficiency.

[0120] Optionally, controlling and / or adjusting the fixing device and / or rotating device and / or driving device according to the force conditions during the bra washing process includes: controlling and / or adjusting the fixing device according to the force conditions during the bra washing process, including: controlling and / or adjusting the tightness of the fixing device in fixing the bra according to the force conditions during the bra washing process; controlling and / or adjusting the compression device according to the force conditions during the bra washing process, including: controlling and / or adjusting the compression force of the compression device on the bra according to the force conditions during the bra washing process; controlling and / or adjusting the driving device according to the force conditions during the bra washing process, including: controlling and / or adjusting the driving device to drive the connection between the driving device and the compression device or to drive the connection between the driving device and the rotating device according to the force conditions during the bra washing process.

[0121] Optionally, controlling and / or adjusting the squeezing force of the compression device on the bra according to the stress conditions of the bra during the washing process includes: controlling and / or adjusting the squeezing stroke of the compression device to adjust the stress value of the bra according to the stress conditions of the bra during the washing process.

[0122] Among them, the extrusion stroke refers to the stroke of the extrusion device relative to the stationary device.

[0123] Optionally, controlling and / or adjusting the tightness of the fastening device on the bra according to the stress conditions during the bra washing process includes: if the stress value of the bra during the washing process is less than or equal to a minimum threshold, adjusting the tightness of the fastening device on the bra to avoid excessive stress on the bra and damage.

[0124] Optionally, the bra washing program includes a spin-drying program, which comprises two stages: a squeezing spin-drying stage, in which the squeezing device applies a squeezing action to the bra; and a centrifugal spin-drying stage, in which the rotating device applies a rotating action to the bra. Based on the stress conditions during the bra washing process, the bra washing program controlling the bra washing structure includes: first executing the squeezing spin-drying stage, then executing the centrifugal spin-drying stage; continuously monitoring the stress conditions on the bra during the squeezing spin-drying stage; and when the stress on the bra reaches a preset maximum threshold, controlling the bra washing mechanism to execute the centrifugal spin-drying stage of the spin-drying program.

[0125] Optionally, the control method further includes the following steps: establishing a correspondence between the stroke position of the compression device and the force value of the bra in advance, and controlling the compression device to move to the set position so that the force value of the bra reaches the preset maximum threshold.

[0126] Optionally, when the dewatering process enters the extrusion dewatering stage, the control drive device is connected to the extrusion device to provide power to the extrusion device; when the dewatering process enters the centrifugal dewatering stage from the extrusion dewatering stage, the control drive device is switched to be connected to the rotation device to provide power to the rotation device.

[0127] Optionally, the centrifugal dehydration stage of the bra washing mechanism includes: performing the centrifugal dehydration stage after continuously applying pressure to the bra at the maximum threshold for a preset time.

[0128] Optionally, the dehydration process also includes a loosening stage; after the centrifugal dehydration stage, the bra washing mechanism is controlled to enter the loosening stage; during the loosening stage, the bra washing mechanism is controlled to adjust so that the stress value on the bra is reduced to a second set value.

[0129] This invention provides a washing control method for a bra washing mechanism. The control method includes the following steps: detecting the force value of the bra in the bra washing mechanism. By adding the step of detecting the force on the bra in the garment handling device, the bra washing mechanism can be adjusted when the force value of the bra is too high or too low, thereby solving the problems of bras being damaged due to excessive force or poor cleaning or dehydration effects due to insufficient force.

[0130] Optionally, the control method further includes the following steps: determining whether the detected force value meets the set conditions; when the force value does not meet the set conditions, adjusting the bra washing mechanism to increase or decrease the force value of the bra. This allows for adjustment of the bra's force value, preventing damage due to excessive force or poor cleaning or dehydration due to insufficient force.

[0131] Optionally, the setting condition can be a threshold range or a set value.

[0132] In one optional embodiment of this application, the condition is set to a force value less than or equal to A1; when a force value greater than A1 is detected, the bra washing mechanism is adjusted to reduce the force value on the bra.

[0133] In another optional embodiment of this application, the condition is set as follows: the force value is greater than or equal to A2; when the force value is less than A2, the bra washing mechanism is adjusted to increase the force value of the bra.

[0134] In another optional embodiment of this application, the condition is set as the force value equal to A1; when the detected force value is greater than A1, the bra washing mechanism is adjusted to reduce the force value of the bra; when the force value is less than A1, the bra washing mechanism is adjusted to increase the force value of the bra.

[0135] Optionally, the dehydration process can be controlled based on the stress value of the bra.

[0136] In an optional embodiment of this application, the control method further includes the following dehydration control step: adjusting the bra washing mechanism to ensure the bra experiences a first set force value and maintaining it for a preset time to achieve squeezing dehydration; then controlling the bra washing mechanism to rotate the bra to achieve centrifugal dehydration. This method, by first squeezing the bra to dehydrate it and then centrifuging it, achieves a better dehydration effect.

[0137] In an optional embodiment of this application, the control method further includes the following dehydration control step: controlling the bra washing mechanism to rotate the bra to achieve centrifugal dehydration; simultaneously controlling the bra washing mechanism to adjust so that the force value gradually increases to achieve squeezing dehydration. In this way, squeezing dehydration is performed simultaneously with centrifugal dehydration, saving dehydration time, and the gradually increasing force value results in better squeezing dehydration.

[0138] In an optional embodiment of this application, the control method further includes the following dehydration control step: controlling the bra washing mechanism to rotate the bra to achieve centrifugal dehydration; simultaneously controlling the bra washing mechanism to adjust so that the force value of the bra alternately increases and decreases to achieve squeezing dehydration. In this way, squeezing dehydration is performed simultaneously with centrifugal dehydration, saving dehydration time, and the alternating force value ensures more thorough squeezing dehydration.

[0139] Optionally, after performing the dehydration control step, the bra washing mechanism is controlled to perform the following loosening control step: the bra washing mechanism is adjusted to reduce the stress on the bra to a second set value. This makes the bra fluffy and easier for the user to remove.

[0140] Optionally, the first set value is the value when the bra is subjected to maximum force in the bra washing mechanism; and / or the second set value is the value when the bra is subjected to minimum force in the bra washing mechanism. This way, centrifugal dehydration is performed when the force is at its maximum, resulting in better dehydration. During the loosening control step, the force on the bra is reduced to a minimum, making it easier for the user to remove the bra.

[0141] In this embodiment of the invention, the bra washing mechanism described above can execute the aforementioned bra washing control program. Thus, the bra washing mechanism can determine whether adjustments are needed based on the stress on the bra, and can also control the timing of dehydration, washing, and loosening steps based on the stress, thereby improving the cleaning effect and efficiency of the bra and preventing deformation and damage.

[0142] According to another aspect of the present invention, a washing control method for a bra washing mechanism is also provided, wherein the bra washing mechanism is as described above; the control method includes the following steps: detecting the force value of the bra in the bra washing mechanism through a force detection unit of the bra washing mechanism. Thus, by adding the step of detecting the force value of the bra, the control of the bra washing mechanism is made more precise, thereby improving the cleaning effect and cleaning efficiency of the bra washing mechanism.

[0143] Optionally, the control method further includes the following steps: controlling the movement of the squeezing device of the bra washing mechanism to adjust the force value of the bra in the bra washing mechanism. This avoids excessive or insufficient force on the bra, and also allows for adjustment of the corresponding force value according to the process to be executed, or execution of the corresponding process based on the force value.

[0144] Optionally, the control method further includes the following steps: determining whether the force value of the bra has reached a set value; if so, controlling the bra washing mechanism to perform a dehydration control step; if not, controlling the squeezing device of the bra washing mechanism to move and adjust the force value of the bra in the bra washing mechanism; or The stroke position of the compression device is pre-established to correspond with the force value of the bra. By controlling the compression device to move to the set position, the force value of the bra reaches the set value.

[0145] In this way, the timing of dehydration is determined based on the stress value, making the dehydration effect more effective and saving more time.

[0146] like Figure 4 As shown, optionally, the bra washing mechanism is the bra washing mechanism described above, and the driving device of the bra washing mechanism includes a rotary motor, a clutch 7, and a cam transmission mechanism 6; the control method executes the following steps in sequence: S1, drainage; S2, Control clutch 7 to switch to the first working state; S3. Control the rotation of the cam transmission mechanism 6, and simultaneously detect the force value of the bra; S4. Determine whether the stress value of the bra has reached the set value. If yes, execute S5; otherwise, continue to execute S3. S5. Control the clutch to switch to the second working state; S6. Control the rotating device to rotate at the set speed for a set time; S7. Control the clutch to switch to the first working state, control the cam transmission mechanism 6 to rotate, so that the extrusion device moves away from the fixed device.

[0147] Optionally, the value can be set to the maximum value. When the force on the bra reaches the maximum, the centrifugal dehydration control program is executed, resulting in better dehydration.

[0148] Optionally, the control method for the bra washing mechanism provided in this application further includes the following steps: Control the clutch 7 to switch to the first working state; control the rotary motor to drive the second cam 62 of the cam transmission mechanism to rotate through the clutch 7, so that the extrusion device moves toward or away from the fixed device or moves the extrusion device; and / or Control the clutch to switch to the second working state; control the rotary motor to drive the rotating device through the clutch to rotate the drain cylinder 4; and / or A correspondence is established between the rotation angle of the second cam 62 of the cam transmission mechanism 6 and the force value in advance. By controlling the rotation angle of the second cam 62 of the cam transmission mechanism, the force value can be adjusted.

[0149] Optionally, such as Figure 14 As shown, in another optional embodiment of this application, the rotation angle of the second cam 62 of the cam transmission mechanism is pre-established to correspond with the force value of the bra cup. By controlling the rotation angle of the second cam 62 to α, the force value of the bra reaches the maximum, and centrifugal dehydration begins.

[0150] In a preferred embodiment of the present invention, a dehydration control method for a bra washing mechanism is provided, including a method for judging the stress on the bra cup and a dehydration control method. The stress on the bra cup is determined by setting a pressure sensor between the squeezing end of the squeezing device and the support frame 1 to form a pressure sensing system. The dehydration control method includes controlling the fixing device to fix the position of the bra cup so that the stress on the bra cup reaches the maximum value. The dehydration control method also includes executing a dehydration program when the stress on the bra cup is the maximum.

[0151] The pressure sensor is attached to the bra cup to form a pressure sensing system. During the rotation of the second cam 62 of the cam transmission mechanism 6, the compression device moves up and down within a reasonable stroke range, and the pressure sensor detects the force on the bra cup in real time.

[0152] Before the dehydration process, the compression device is moved to compress the bra cups, securing the bra firmly between the compression device and the flexible support frame 1. This maximizes the pressure on the cups and prevents the bra from shifting or deforming due to centrifugal force during dehydration. The maximum pressure value for the cups is as follows: Figure 14As shown, when the rotation angle of the second cam 62 of the cam transmission mechanism 6 is α, the pressure sensor detects that the pressure on the bra cup has reached its maximum. At this time, the controller 7 stops the transmission with the cam transmission mechanism 6 and determines that the dehydration program is to be executed. The dehydration program controls the bra washing mechanism to continuously apply pressure and maintain it for a certain period of time when the bra cup reaches the maximum force value. At the same time, the transmission mode of the clutch is switched so that the clutch and the rotating device rotate to perform high-speed centrifugal dehydration. The high-speed centrifugal dehydration speed is divided into at least 3 gears. The gears can be set manually, and only one speed can be set at a time.

[0153] The bra washing mechanism and its control method provided in this application use a pressure sensor installed between the squeezing device and the support frame 1 to determine the force on the bra cups. The pressure sensor controls the bra washing mechanism to execute the dehydration program when the cups are under maximum force, achieving a better dehydration effect and preventing the bra from being damaged due to excessive force, thus solving a user pain point. By adjusting the squeezing device and the support frame 1, the pressure on the bra sandwiched between the support frame 1 and the support cover 2 can be adjusted to prevent the bra from shifting or deforming during the dehydration process. The dehydration method selects two methods: squeezing dehydration by the squeezing device and the support frame 1 on the bra cups, and high-speed centrifugal dehydration, to achieve a better dehydration effect.

[0154] The washing control method for the bra washing mechanism provided in this application actually provides a method for judging the force on the bra, thus solving the problem of extending the service life of the bra.

[0155] This invention also provides a bra washing control method applied to the aforementioned washing machine. The washing machine has a mixed washing mode, which includes a squeezing washing process and a spray washing process. In the mixed washing mode, the squeezing washing process and the spray washing process are driven by the same squeezing device. This allows two different washing methods to be achieved with a single power component, thereby reducing costs while improving the washing effect on bras.
