Description

Technical Field

[0001] The invention relates to the field of removing water from the surface or inside of an object, and in particular to an adaptive spin-drying liner and a spin-drying machine. Background Art

[0002] In industrial and consumer scenarios, when it is often necessary to remove water from the surface or inside of an object (i.e., a solid object to be dried, hereinafter referred to as the object), the methods used are generally as follows in principle: Air drying, using a fan to blow air or other inert gas onto the surface and / or inside of an object to evaporate water quickly, such as the Chinese utility model patent with authorization announcement number "CN212538543U"; Drying: Since the evaporation rate of water is positively correlated with the ambient temperature, the air or inert gas is heated on the basis of the above-mentioned wind drying to obtain a relatively faster evaporation rate (wind drying), such as the Chinese invention patent application with publication number "CN114892379A"; Centrifugal drying is achieved by means of a spin-drying drum with water holes. The objects to be dehydrated are placed in the spin-drying drum, and then the spin-drying drum is driven to rotate by a power unit (usually a motor), so that the objects in the spin-drying drum obtain centrifugal force. Under the action of the centrifugal force, water is gradually thrown out from the surface and inside of the objects and discharged through the water holes. A method well known to consumers is the spin-drying of household washing machines (including pulsator washing machines and drum washing machines), as well as the Chinese utility model patent with the authorization announcement number "CN218096903U".

[0003] Since the centrifugal drying method can obtain a large centrifugal force and drying effect in a limited space, it is widely used. The relative displacement between the object and the drying drum, and between objects causes collision, extrusion, friction, and excessive pulling, resulting in irreversible overall or partial deformation, surface scratches, and even damage. The principle of its generation is: the object is directly placed in the drying drum, and the posture of the object is random and cannot be guaranteed. At least when accelerating or decelerating, the object itself may be relatively displaced relative to the drying drum, and this relative displacement will cause the object to be squeezed, collided, and rubbed relative to the drying drum. In order to try to solve the above-mentioned adverse effects, the Chinese utility model patent with the authorization announcement number "CN214077265U" presses the object through a rigid body (filter screen), thereby achieving fixation between the object and the drying drum, avoiding relative displacement between the object and the drying drum, and relative displacement between objects. However, the pressing force between the rigid body and the object still exists, and this pressing force will still produce the above-mentioned irreversible overall or partial deformation, surface scratches, and even damage.

[0004] In particular, due to the material properties of the object itself (as disclosed in CN111284009A and CN109016496A, the resin is not completely cured and shaped when 3D printing is just completed, and heat treatment is required to fully cure it. However, before heat treatment, the uncured resin attached to the surface of the 3D printed product needs to be cleaned and spun dry), the mechanical pressing of the rigid body will still cause deformation due to being squeezed and unable to recover the original shape after collision. If the material itself is soft, it will also cause scratches due to the above friction, and even cause deformation and damage to the object due to excessive pulling and squeezing. Of course, in order to consider the efficiency of the drying operation, multiple objects are often put into the drying drum at the same time. The collision, entanglement and friction between the multiple objects will further aggravate the above deformation, produce scratches, local deformation and even damage.

[0005] Therefore, in order to solve the above problems, an embodiment of the present invention provides an adaptive spin-drying liner and a spin dryer. Summary of the invention

[0006] The embodiments of the present invention provide an adaptive spin liner and a spin dryer, which at least solve the problem of fixing the posture of an object by means of centrifugal force during spin drying without using a rigid part to apply pressure.

[0007] A first aspect of an embodiment of the present invention provides an adaptive spin-drying liner, comprising: a load-bearing portion; and The connecting portion extends along a first direction and sequentially forms a smaller gap end and a larger gap end, the first direction is not in the rotation plane of the spin drying drum, the bearing portion is fixed to the smaller gap end, and the smaller gap end can be maintained in an initial position and an operating position in the radial direction, wherein: In the initial position, the bearing portion extends obliquely inward to form a supporting groove opening upward or a hanging groove opening downward, and the gap between the connecting portion and the spin-drying drum gradually increases along the first direction; In the working position, a power unit sequentially drives the spin-drying drum to rotate around the rotation axis, drives the adaptive spin-drying liner to rotate, the gap is at least partially reduced, and the reduction range of the gap gradually increases along the first direction.

[0008] A second aspect of an embodiment of the present invention provides a spin dryer, comprising any of the above: Power unit; A spin drying drum, driven by the power unit, rotates around the rotation axis; The adaptive spin-drying liner reduces the gap at least partially by means of the centrifugal force rotating with the spin-drying drum.

[0009] The beneficial effects of the embodiments of the present invention include at least: In the initial position, when the power unit drives the spin-drying drum to start rotating, the object can be placed on the support groove with the opening upward (or suspended under the suspension groove by a flexible rope, etc.), and the load-bearing part extends obliquely upward and inward to form an inclined support slope. Under the support of the slope, one surface of the object (for example, when the object to be cleaned is a shoe, the surface is the bottom surface of the shoe) can be attached to the inner wall of the spin-drying drum, and the object can be immobilized without the help of any solid before the spin-drying operation; The gap between the connecting part and the spin-drying drum provides a space for the connecting part to move outwards under the action of centrifugal force, thereby allowing the connecting part to move outwards under the action of centrifugal force. At the same time, since the gap gradually increases from the smaller gap end to the larger gap end, the maximum distance allowed for the movement of the connecting part is different. Taking the supporting groove as an example, the larger gap end and the bearing part are at the bottom, and the smaller gap end is at the top. At this time, when the centrifugal force increases to a sufficient level, the entire connecting part is allowed to be tightly attached to the spin-drying drum to obtain the maximum centrifugal force and ensure the spin-drying effect. The support groove opens upwards and the hanging groove opens downwards, thus providing space for placing and taking out objects in the vertical direction, which is convenient for taking and putting objects. It also provides the user with an observation field of view, which can facilitate the observation of the posture of the placed or hung objects, and adjust them at any time when the posture is found to be wrong; In the working position, the object can be supported by the inner side of the connection part under the action of centrifugal force, and the contact area is large, thus avoiding irreversible plastic deformation caused by material properties (such as incompletely cured resin) during the spin-drying operation.

[0012] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] As described in the background technology, in order to simultaneously achieve the following effects: in the initial state (the state without rotation), objects can be conveniently placed, and the contact pressing without any rigid parts can maintain a solid posture in both the initial state and the working state and has no displacement relative to the spin dryer drum, the first aspect of the embodiment of the present invention discloses an adaptive spin dryer liner 1, see Figures 1 to 38 , which comprises a bearing portion 11 and a connecting portion 12. Wherein: Figures 1 to 8The adaptive spin-drying liner 1 of the embodiment has two sections (in the middle position along the first direction D) and multiple sections (specifically six) in the circumferential direction, and the adaptive spin-drying liner 1 is in the working position; Figures 9 to 22 In the embodiment, the adaptive spin-drying liner 1 is not segmented up and down (in the middle of the first direction D), and has multiple (specifically eight) circumferential sections, and Figures 9 to 18 The adaptive spin-drying liner 1 is in the initial position, Figures 19 to 22 The adaptive spin-drying liner 1 is in the working position; Figure 23 to Figure 25 The adaptive spin-drying liner 1 structure of the embodiment Figures 9 to 22 The difference is that the openings of the adaptive spin-drying liner 1 and the spin-drying drum 2 are both downward, that is, the bearing portion forms a hanging groove 112; Figure 26 to Figure 33 The adaptive spin-drying liner of the embodiment is an integral structure, wherein: the bearing portion 11 forms a supporting groove 111, Figure 26 to Figure 29 is the initial position, Figure 30 to Figure 33 For work location; Figure 34 to Figure 36 The adaptive drying liner of the embodiment is an integral structure. Figure 26 to Figure 33 The difference is that the openings of the adaptive spin-drying liner 1 and the spin-drying drum 2 are both downward, that is, the bearing portion 11 forms a hanging groove 112; Fig.37 and Fig.38 The embodiment is a schematic structural diagram of an adaptive spin-drying liner 1 installed in a spin-drying drum via an elastic member.

[0016] Continue to see Fig.10 , Fig.25 and Fig.36 The connecting portion 12 extends along a first direction D and sequentially forms a smaller gap end 122 and a larger gap end 121. The first direction D is not in the rotation plane S (perpendicular to the rotation axis X) of the spin drying drum 2, thereby allowing the gap G between the connecting portion 12 and the spin drying drum 2 to change in the depth direction (the direction of the rotation axis X of the spin drying drum 2), thereby forming the above-mentioned smaller gap end 122 and larger gap end 121.

[0017] The bearing portion 11 is fixed to the smaller gap end 122, and the smaller gap end 122 can be maintained in the initial position and the operating position in the radial direction (the radial direction with a point on the rotation axis X of the spin drying drum 2 as the center; at the same time, the following descriptions of "inward" and "outward" are also described with reference to the rotation axis X of the spin drying drum 2, that is, inward refers to the direction close to the rotation axis X, and outward refers to the direction away from the rotation axis X), wherein: In the initial position, the bearing portion 11 extends obliquely inward to form a support groove 111 (such as Figures 1 to 8 , Figures 9 to 22 and Figure 26 to Figure 33 ) or a downwardly opening suspension groove 112 (as shown Fig.23 Fig.25 as well as Figure 34 to Figure 36 As shown in FIG. 1 ), the gap G between the connecting portion 12 and the drying drum 2 gradually increases from the smaller gap end 122 to the larger gap end 121; In the working position, a power unit 3 sequentially drives the spin-drying drum 2 to rotate around the rotation axis X, drives the adaptive spin-drying liner 1 to rotate, the gap G is at least partially reduced, and the reduction degree of the gap G gradually increases along the first direction D.

[0018] In the initial position, when the power unit 3 drives the spin-drying drum 2 to start rotating, the object can be placed on the support groove 111 with an opening upward (or suspended under the suspension groove 112 by a flexible rope, etc.), and the load-bearing portion 11 extends obliquely upward and inward to form an inclined support slope. Under the support of the slope, a surface of the object (such as the bottom surface of the shoe when the object to be cleaned is a shoe) can be attached to the inner wall of the spin-drying drum 2, and the object can be kept immobile without the help of any solid before the spinning operation.

[0019] The gap G between the connecting portion 12 and the spin-drying drum 2 provides a space for the connecting portion 12 to move outward under the action of centrifugal force, thereby allowing the connecting portion 12 to move outward under the action of centrifugal force. At the same time, since the gap G gradually increases from the smaller gap end 122 to the larger gap end 121, the maximum distance allowed for the connecting portion 12 to move is different. Taking the supporting groove 111 as an example, the larger gap end 121 and the bearing portion 11 are at the bottom, and the smaller gap end 122 is at the top. At this time, when the centrifugal force increases to a sufficient size, the entire connecting portion 12 is allowed to be close to the spin-drying drum 2 to obtain the maximum centrifugal force and ensure the spinning effect.

[0020] The internal spin drying chamber 126 of the spin drying drum 2 is substantially cylindrical, thereby achieving maximum space utilization. Combined with the gradual increase of the gap G along the first direction D, it can be directly determined that the adaptive spin drying liner 1 is generally a (hollow inside) frustum or an inverted frustum structure, or a portion of the two divided along the circumferential direction.

[0021] When the shape of the adaptive spin-drying liner 1 is an inverted frustum, the smaller gap end 122 is located above the larger gap end 121; the bearing portion 11 extends upward and inward to form a support groove 111. This structure is suitable for the placement of objects, such as shoes, and is particularly suitable for 3D printed products (such as 3D printed shoes) that have been completed but not fully cured as described in the background technology. At this time, the openings of the adaptive spin-drying liner 1 and the spin-drying drum 2 are both set upward, so that they can be easily operated from above.

[0022] When the shape of the adaptive spin-drying liner 1 is a frustum, the smaller gap end 122 is located below the larger gap end 121; the bearing portion 11 extends downward and inward to form a hanging groove 112. At this time, there is a space below the hanging groove 112 for convenient entry and exit of objects, and objects can be conveniently placed and observed from below the hanging groove 112, that is, the openings of the adaptive spin-drying liner 1 and the spin-drying drum 2 are both set downward, so that they can be conveniently operated from below.

[0023] The adaptive spin-drying liner 1 is made of a porous material or has a through hole for water to pass through. This ensures that during the spin-drying operation, water can quickly flow to the water hole 21 of the spin-drying drum 2 and flow out. The porous material can be selected from 3D printed materials with multiple lattices, such as the patents CN111407040A, CN111438932A and CN111418956A previously applied for by the applicant. Of course, other porous materials can also be selected, such as polyurethane, etc. For the sake of simplicity of description, they are not listed one by one.

[0024] It should also be noted that the gap G is adaptively adjusted as the centrifugal force changes, and this concept can be achieved by at least one of the following: Elastic deformation of the elastic member disposed between the connecting portion 12 and the drying drum 2; Elastic deformation of the connecting portion 12.

[0025] Which means to be used specifically, or both means to be used simultaneously, can be flexibly selected according to actual requirements. If the gap G to be achieved is relatively large, and the elastic deformation amount of the connecting part 12 alone is insufficient to provide the larger gap G, the elastic deformation of the elastic member can be added; taking a step back, if the gap G to be achieved is sufficient to be provided by the elastic deformation amount of the connecting part 12 alone, then only the second means can be used. Of course, due to space limitations, the inventor will not list other considerations and selection methods one by one.

[0026] In addition, in order to further increase the deformation of the adaptive spin-drying liner 1 in the longitudinal section (a plane parallel to the rotation axis X), the inventors have made the following design: a transverse groove 123 is provided on the outer side of the connecting portion 12, and the transverse groove 123 extends along the circumferential direction of the rotation axis X. In the process of moving from the initial position to the operating position, the upper and lower sides of the transverse groove 123 are squeezed under the action of centrifugal force, so that the opening of the transverse groove 123 gradually decreases. When the centrifugal force decreases or disappears, the transverse groove 123 returns to the initial position, thereby increasing its deformation. Thus, a wider adjustment range of the gap G is provided to adapt to the spin-drying of large-sized objects. At the same time, the third means and the three means of the aforementioned two means can be selected by one, two or both. In particular, when only the second and third means are used, it is only necessary to change the material and structure of the adaptive spin-drying liner 1 itself, so as to avoid the introduction of elastic parts and their installation requirements. In particular, the elastic parts are often made of metal, and the spin-drying operation is a humid environment, which can cause the metal elastic parts to corrode and fail, thereby increasing the service life.

[0027] The corner positions of the parts and parts of the adaptive spin-drying liner 1, such as the transverse groove 123, the intersection position of the distal end of the connecting part and the side, etc., can be straight lines (such as Figures 9 to 36 The embodiment shown in the figure), the arc, parabola and other smooth transition styles can also be used (as shown in Figure 1 to Figure 8 In the embodiment of the present invention, a smooth transition is adopted to avoid stress concentration and improve the fatigue resistance of repeated deformation.

[0028] Since the smaller gap end 122 requires a smaller deformation than the larger gap end 121 to form an equal gap G in the working position, the opening size of the transverse groove 123 gradually decreases from the larger gap end 121 to the smaller gap end 122. This ensures that in the working position, the adaptive spin-drying liner 1 is cylindrical as a whole, avoiding the centrifugal force caused by the conical shape from forming a component force on the inclined inner wall, and ensuring that the object does not move along the depth direction of the spin-drying drum in the working position.

[0029] Similar to the concept of the transverse groove 123 , in order to increase the radial deformation, a longitudinal groove 124 is provided on the outer side of the connecting portion 12 , and the longitudinal groove 124 extends in a direction parallel to the rotation axis X. The longitudinal groove 124 gradually decreases from the initial position to the working position.

[0030] The elastic deformation of the connecting portion 12, the transverse groove 123, and the longitudinal groove 124 are all based on the fact that the adaptive spin-drying liner 1 is an elastomer.

[0031] In addition, the transverse groove 123 and the longitudinal groove 124 further facilitate the water to flow through the water hole 21 and then be discharged.

[0032] If the adaptive spin-drying liner 1 is a rigid body (it does not deform under the action of centrifugal force, strictly speaking, its deformation is negligible compared to the gap G), then the gap G is adaptively adjusted with the centrifugal force through an additional elastic member. Fig.37 The elastic member includes a first elastic member 91 between the larger gap end 121 and the spin-drying drum 2, and a second elastic member 92 between the smaller gap end 122 and the spin-drying drum 2; the first elastic member 91 and the second elastic member 92 undergo different degrees of deformation under the action of centrifugal force (the deformation of the first elastic member 91 is greater than that of the second elastic member 92 under the same centrifugal force). The second structure, see Fig.38 The smaller gap end 122 is rotatably mounted on the drying drum 2 in the longitudinal section of the drying drum 2 (for example, by gluing); a third elastic member 93 is provided between the larger gap end 121 and the drying drum 2 .

[0033] After the above-mentioned bearing part 11 is set, under the action of centrifugal force, the object is positioned on the inner wall of the spin-drying drum in the radial direction. The curvature of the inner wall of the connecting part 12 can resist the object from tilting forward (it may tilt forward when the rotation is decelerated) or backward (it may tilt backward when the rotation is accelerated) in the rotation direction to a certain extent. In order to avoid the occurrence of such tilting, the connecting part 12 extends inward at the end opposite to the bearing part 11 to form a cover part 13; the connecting part 12 has an inwardly extending limiting protrusion 125, and any two adjacent limiting protrusions 125 and the bearing part 11 and the cover part 13 therebetween define a spin-drying chamber 126 opening inward.

[0034] By constructing the spin-drying chamber 126, any two adjacent limiting protrusions 125 can limit the object from both sides, the cover 13 from the top, the bearing part 11 from the bottom, and the connecting part 12 from the far end in the radial direction, so as to ensure its posture. In addition, the size of the spin-drying chamber 126 does not cause pressure on the space occupied by the object whether in the initial position or in the working position. At the same time, the limiting protrusion 125 is formed by the connecting part 12 extending radially inward, that is, it is a part of the connecting part 12. When the connecting part 12 is made of an elastomer, the two limiting protrusions 125 of the same spin-drying chamber 126 will adaptively approach each other with the centrifugal effect. This approach can further reduce the opening of the spin-drying chamber 126 until it is smaller than the outer contour of the object, so as to strictly prevent the extremely small probability of the object escaping from the opening due to factors such as vibration in the working position.

[0035] In order to spin dry multiple small objects at the same time, the spin drying chambers 126 are evenly distributed in the circumferential direction; and / or, the spin drying chambers 126 are at least one layer in the depth direction of the spin drying drum 2. In particular, after the upper and lower layers are formed, the upper and lower parts of each spin drying chamber 126 are blocked by the cover 13 and the bearing part 11 respectively. At this time, the truncated cone or inverted truncated cone formed by "the gap G between the connecting part 12 and the spin drying drum 2 gradually increases along the first direction D" can make the objects be taken and placed and the posture of observation of placement is achieved.

[0036] An embodiment of the adaptive spin-drying liner 1 is as described above, wherein the spin-drying chamber 126 is constructed by the limiting protrusions 125 on both sides, the cover 13 on the top and the bearing part 11 at the bottom, and can be prepared by injection molding, casting, forging, etc. It can also be prepared by 3D printing. When the 3D printing method is used for integrated preparation, since the cover 13 and the bearing part 11 are one above and one below, they both occupy more raw materials and have a large weight, so they need to be supported during printing, especially Figure 4-Figure 8 In the structure shown, the cover 13 and the bearing part 11 extend inward more than the limiting protrusion 125, and the more extended part needs more support. At the same time, if the overall printing size is large, it is rarely met by a 3D printer. Even if it can barely meet the requirements, the printing cost will rise sharply. In summary, in order to use 3D printing to prepare without increasing printing support (occupying raw materials and wasting time), the inventor prints the adaptive spin-drying liner 1 in sections along the direction from the cover 13 to the bearing part 11. The specific segmentation method can be any of the following: The cover portion 13 and part of the connecting portion 12 are integrally formed by 3D printing, and the bearing portion 11 and the remaining part of the connecting portion 12 are integrally formed by 3D printing (eg Figures 1 to 8 as shown in the embodiment); The cover portion 13, the connecting portion 12 and the bearing portion 11 are integrally formed by 3D printing; The cover portion 13 or the bearing portion 11 and the connecting portion 12 are integrally formed by 3D printing. Accordingly, the bearing portion 11 or the cover portion 13 is integrally formed by 3D printing.

[0037] It should also be noted that the various parts of the segment can be connected by connecting parts such as ropes, or by bonding and other methods.

[0038] In order to further reduce the size of the adaptive spin-drying liner 1, the adaptive spin-drying liner 1 is a plurality of liner 1 uniformly arranged along the circumferential direction. The plurality of liner 1 can be connected by connecting members such as ropes or bonding.

[0039] Another embodiment of the adaptive spin-drying lining 1 is an integrated structure, and there is no upper and lower segmentation or circumferential division as mentioned above. This type of structure is more suitable for casting, especially lost foam casting (also known as full-mold casting, which is a new casting method in which paraffin or foam models with similar size and shape to the casting are bonded together into a model cluster, coated with refractory paint and dried, buried in dry quartz sand for vibration molding, poured under negative pressure, vaporized the model, and liquid metal occupies the model position, and solidifies and cools to form a casting.).

[0040] It should also be noted that in the working position, the gap G is reduced to 0, see Figure 4 , Fig.19 and Fig.32 That is, the adaptive spin liner 1 is close to the inner wall of the spin drum 2, the inner wall of the spin drum 2 is vertical, and the rotation axis X is vertical, so as to ensure that the bearing part 11 extends outward to the maximum extent, obtain sufficient centrifugal force, and ensure the spin effect.

[0041] In the working position, assuming that the angle between the object and the corresponding part of the bearing part 11 and the corresponding part of the object and the connecting part 12 is 90°, the inner end of the bearing part 11 is horizontal or slightly bent downward (such as a straight line bend of 1-5° as a whole, or an arc bend), such as Figures 9 to 38 As shown, in this posture, the pressure of the object on the bearing part 11 is reduced as much as possible to avoid deformation of the object under this pressure. At the same time, as mentioned above, although the object is confined in the spin-drying chamber 126, the spin-drying chamber 126 must be slightly larger than the outer contour of the object for the sake of easy access and avoidance of squeezing the object. At this time, a slight displacement of the object relative to the spin-drying drum 2 may also occur (depending on how much larger the spin-drying chamber 126 is than the outer contour of the object). By reducing the pressure as much as possible, even if this slight displacement occurs, no scratches are generated as much as possible or only extremely slight scratches are generated (which can be eliminated by later grinding), making this structure particularly suitable for materials that undergo plastic deformation due to centrifugal force (such as the incompletely cured resin mentioned above).

[0042] In the working position, the inner end of the bearing portion 11 may also be slightly bent upward (e.g., the whole body is bent in a straight line by 1-5°, or in an arc shape), such as Figures 1 to 8 As shown, this design is exactly the opposite of "horizontally or slightly bent downward", and is specifically designed to increase the pressure and friction, so that the generated friction drives the object to rotate synchronously with the spin-drying drum 2 in a shorter time. Obviously, this structure is suitable for materials that will not undergo plastic deformation due to centrifugal action; of course, this structure is also suitable for the situation where the part of the object opposite to the bearing portion 11 is warped in a direction away from the bearing portion 11 to ensure that it does not contact the bearing portion 11, and the above-mentioned effect of reducing pressure and friction can also be achieved.

[0043] Of course, the adaptive spin dryer liner 1 can also have any position between the initial position and the operating position, which can be adjusted by the elastic modulus, free length of the elastic part or by the elastic modulus, free length of the adaptive spin dryer liner 1 or by the size of the centrifugal force (rotation speed of the spin dryer drum 2, inner diameter of the spin dryer drum).

[0044] The first driving force for the adaptive spin-drying liner 1 to rotate with the spin-drying drum 2 is that, in the initial position, the larger gap end 121 is fixed to the spin-drying drum 2 by a connecting member, which may be a bolt, a screw, or adhesive, etc. The portion outside the larger end of the adaptive spin-drying liner 1 does not contact the spin-drying drum 2 at the beginning due to the existence of the gap G, and gradually expands outward as the centrifugal force increases until it is closely attached to the inner wall of the spin-drying drum 2 to generate the above-mentioned friction force.

[0045] The adaptive spin-drying liner 1 rotates with the spin-drying drum 2. The second is that the friction force generated between the connecting portion 12 and the spin-drying drum 2 due to centrifugal action provides the power for the adaptive spin-drying liner 1 to rotate. The adaptive spin-drying liner 1 is expanded outward as a whole by the centrifugal force until it is close to the inner wall of the spin-drying drum 2. In particular, the adaptive spin-drying liner 1 is made of 3D printed curing resin, and the inner wall of the finished spin-drying drum 2 (usually made of stainless steel) has a sufficient friction coefficient, which can increase the driving force for rotation.

[0046] The second part of the embodiment of the present invention discloses a spin dryer, which comprises any of the above-mentioned power units 3, a spin dryer drum 2 and an adaptive spin dryer liner 1. The spin dryer drum 2 rotates around the rotation axis X under the drive of the power unit 3; the gap G is at least partially reduced by the centrifugal force generated by the rotation of the spin dryer drum 2. Thus, the adaptive spin dryer liner 1 and the object transition from the initial position to the working position, completing the spin drying operation.

[0047] A method of power unit 3, see Fig.10 , including a motor 31, a driving pulley 32, a driving belt 33, a driven pulley 34 and a flange 35 which are sequentially connected. The flange 35 is fixed to the bottom of the spin-drying drum 2, which increases the force-bearing area of ​​the spin-drying drum 2, improves the rigidity of the spin-drying drum 2, and ensures the reliable performance of the spin-drying operation.

[0048] In addition, a transverse groove 123 is provided on the outer side of the connecting portion 12, at least referring to Fig.10 , Fig.19 , Fig.25 , Fig.28 , Fig.32 and Fig.36 The spin drying drum 2 is provided with a through water hole 21, and each transverse groove 123 corresponds to at least one water hole 21. Water is discharged along the transverse groove 123 → the water hole 21 corresponding to the transverse groove 123, which improves the water discharge efficiency and ensures the spin drying effect.

[0049] See also Fig. 9 and Fig.10 Another embodiment of the spin dryer may further include an outer drum 4, a drain pipe 5 and a top cover 8. The outer drum 4 is provided outside the spin dryer drum 2 to receive the water flowing out through the water hole 21; the drain pipe 5 is installed on the outer drum 4 and is at least configured to drain the water in the outer drum 4; the top cover 8 can be opened and closed (such as by hinged shaft) to cover the opening of the outer drum 4. A shell 6 is also fixedly provided outside the outer drum 4. When the openings of the spin dryer drum 2 and the outer drum 4 face upward, an outer drum support portion 61 and a motor support portion 62 are also provided inside the shell 6, which are used to support the outer drum 4 and the motor 31 respectively. At least three leveling feet 7 are installed at the bottom of the shell 6, which are evenly distributed on the circumference of the rotation axis X. Four feet are shown in the figure, and of course other numbers can be used.
