Detailed Implementation

[0046] To enable those skilled in the art to more clearly understand this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0047] Figure 1 shows a structural schematic diagram of a garment processing device in the related art, and Figure 2 shows an exploded view of Figure 1. Referring to Figures 1 and 2, the garment processing device in the related art includes a drive mechanism 101 and a washing drum for storing clothes. The washing drum includes an inner drum 201 and an outer drum 102. The inner drum 201 is connected to the output of the drive mechanism 101. Under the drive of the drive mechanism 101, the inner drum 201 is rotatably positioned within the outer drum 102 to clean the clothes. The garment processing device can be a drum washing machine or a washer-dryer.

[0048] In related technologies, after the clothing processing equipment has been running for a period of time, the inner wall of the outer drum 102 and the inner and outer walls of the inner drum 201 inevitably accumulate dirt that is difficult to clean. If this dirt is not cleaned in time, bacteria will easily grow in the humid environment of the washing drum over the years, which will not only affect the service life of the washing drum, but also cause secondary pollution to the clothes and affect the health of users.

[0049] Based on the above-mentioned technical problems, this disclosure provides a garment processing device. The design concept is that the inner drum 201 can be quickly removed from the garment processing device to facilitate cleaning of the inner and outer walls of the inner drum 201, as well as the inner wall of the outer drum 102. It is even possible to replace the inner drum 201 with a new one, so as to keep the inside of the washing drum of the garment processing device clean and hygienic, improve the service life of the washing drum, avoid secondary pollution of the clothes, avoid affecting the health of users, and improve the user experience.

[0050] Based on the above design concept, this disclosure provides a garment processing device, including: an inner tub; an outer tub assembly, the outer tub assembly including an outer tub and a drive mechanism for driving the inner tub to rotate; a first fitting, the first fitting having an assembly portion; a second fitting, the second fitting having multiple engaging portions spaced circumferentially around the assembly portion; and a drive member, the drive member switching between a first state and a second state to connect or separate the multiple engaging portions from the assembly portion; in the first state, the drive member applies a radial locking force between the engaging portions and the assembly portion, connecting the engaging portions and the assembly portion; in the second state, the drive member releases the radial locking force between the engaging portions and the assembly portion, separating the engaging portions and the assembly portion; wherein, one of the first fitting and the second fitting is connected to the inner tub, and the other is connected to the outer tub assembly. Therefore, by controlling the action of the drive member, the first fitting and the second fitting can be locked or separated, allowing the inner tub to be quickly installed onto or removed from the outer tub assembly. The following description, with reference to Figures 2-22, details how the engagement portion of the second assembly and the assembly portion of the first assembly can be connected or separated by controlling the operation of the drive component.

[0051] Understandably, the first or second assembly connects to the outer cylinder assembly, either to the outer cylinder or to the drive mechanism. When connected to the drive mechanism, the assembly connected to the drive mechanism rotates with the drive mechanism, and the assembly connected to the inner cylinder rotates with the inner cylinder. This means there is no relative rotation between the first and second assemblies, which helps extend their service life. When the first or second assembly is connected to the outer cylinder, it may not rotate, thus allowing for relative rotation between the first and second assemblies.

[0052] Understandably, the drive unit can be manually driven by the user, or it can be driven by the control system of the garment handling equipment after the user issues a command. When the drive unit is manually driven by the user, it can be positioned in a location convenient for the user to operate, such as within the garment receiving cavity enclosed by the inner drum.

[0053] Understandably, the first and second states can be positional states. For example, in the first state, the drive component is in a first position, and in the second state, the drive component is in a second position; the first and second positions are different. Alternatively, the first and second states can be energized states. For example, the first state is energized, and the second state is de-energized; or the first state is de-energized, and the second state is energized. Considering that the inner and outer cylinder assemblies are in a locked state for a longer period than they are in a separable state, the first state can be de-energized, and the second state energized to reduce power consumption.

[0054] It is understandable that the radial locking force applied by the drive component between the engaging part and the assembly part can refer to the direct or indirect application by the drive component, or it can be applied by a part of the drive component or the entire drive component.

[0055] It is understandable that the multiple engaging parts are arranged circumferentially around the assembly part, which can be either circumferentially spaced around the inner circumference of the assembly part or circumferentially spaced around the outer circumference of the assembly part.

[0056] The engagement parts are spaced apart around the inner circumference of the assembly, which may mean that the assembly is a cylindrical or other component with a central cavity. In this case, the engagement parts are located inside the assembly, distributed along its inner circumference, and spaced apart from each other. When the drive switch states to open the engagement parts, the drive applies a radial locking force between the engagement parts and the assembly, locking them together. When the drive switch states to close the engagement parts, the drive no longer applies the radial locking force, and the engagement parts can be separated from the assembly. It is understood that the state of opening and closing depends on the specific fit between the assembly and the engagement parts. For example, when the circumferential distance between the engagement parts is large enough to achieve circumferential locking between them, it is in the open state; when the circumferential distance is insufficient to achieve circumferential locking, it is in the closed state.

[0057] The engaging portions are circumferentially spaced around the outer periphery of the assembly, which means the assembly may be a rod-shaped or other component with a distinct outer periphery. The engaging parts are distributed along this outer periphery, spaced a certain distance apart. When the drive switch states to close the multiple engaging portions, the drive applies a radial locking force between the engaging portions and the assembly, locking them together. When the drive switch states to open the multiple engaging portions, the drive no longer applies the radial locking force, and the multiple engaging portions can be separated from the assembly. It is understood that the state of opening and closing depends on the specific mating relationship between the assembly and the engaging portions. For example, when the circumferential distance between the multiple engaging portions is small enough to achieve circumferential locking between the engaging portions and the assembly, it is in the closed state; when the circumferential distance between the multiple engaging portions is insufficient to achieve circumferential locking between the engaging portions and the assembly, it is in the open state.

[0058] Understandably, the multiple engaging parts are arranged circumferentially around the assembly part, and the locking force between the engaging parts and the assembly part is radial (i.e., the direction of the line connecting the center point of the cross-section of the multiple engaging parts and the outer periphery of the cross-section). This makes the installation of the engaging parts and the assembly part more stable and ensures the concentric rotation of the inner cylinder and the drive mechanism after assembly.

[0059] For example, the engaging part and the assembly part can be connected in various ways, such as snap-fit ​​or interlocking. For example, the engaging part includes a spring piece with a latch at one end, and the assembly part includes a groove; when the engaging part is connected to the assembly part, the latch is at least partially located in the groove; when the latch disengages from the groove, the engaging part and the assembly part can be separated. For example, the engaging part includes a ball, and the assembly part includes grooves corresponding to the balls; when the engaging part is connected to the assembly part, the balls are pressed into the grooves; when the balls are not pressed into the grooves, for example, when they can move freely between the grooves and the space outside them, the engaging part and the assembly part can be separated.

[0060] The following is an exemplary description of a scheme in which the engaging part is spaced circumferentially around the inner circumference of the assembly part.

[0061] For example, the driving member can be a rod-shaped object, and the engaging portion can be a long strip-shaped spring with a protrusion at one end. The engaging portion includes an end away from the first assembly and an end close to the first assembly. Multiple engaging portions are circumferentially spaced around a central axis, forming an inner cavity of the engaging portion. The end of the engaging portion away from the first assembly can be fixed. From the end away from the first assembly to the end close to the first assembly, the multiple engaging portions can be in a state of slightly converging towards the center. That is, at the end away from the first assembly, the circumferential spacing of the multiple engaging portions can be greater than the circumferential spacing of the multiple engaging portions at the end close to the first assembly. The assembly portion includes a groove into which the protrusion on the engaging portion can be inserted. When the driving member is inserted into the inner cavity of the engaging portion, at least the area where the protrusion is located is opened, the protrusion is inserted into the groove of the assembly portion, and the first assembly and the second assembly are locked. When the driving member is pulled out of the inner cavity of the engaging portion, at least the area where the protrusion is located returns to its original state, the protrusion is dislodged from the groove of the assembly portion, and the first assembly and the second assembly can be separated.

[0062] Figure 3 shows an assembly schematic diagram of the inner cylinder 201 in one embodiment, and Figure 4 shows an exploded schematic diagram of Figure 3. Referring to Figures 1-6, in one embodiment, one axial end of the first assembly 300 is connected to the drive mechanism 101 of the outer cylinder assembly 100, and the second assembly 500 is connected to the bottom of the inner cylinder. The drive member 400 can be inserted into multiple engaging portions 501 of the second assembly 500 to expand the multiple engaging portions 501, connecting the multiple engaging portions 501 with the assembly portion 301 of the first assembly 300, so that the inner cylinder 201 is assembled on the outer cylinder assembly 100 (as shown in Figure 5). Alternatively, the drive member 400 can separate from the multiple engaging portions 501 to retract the multiple engaging portions 501, thereby separating the multiple engaging portions 501 from the assembly portion 301 of the first assembly 300, and then disassembling the inner cylinder 201 from the outer cylinder assembly 100 (as shown in Figure 6).

[0063] Figure 7 shows a schematic diagram of the structure of the first assembly 300 in Figure 3. Referring to Figures 7 and 8, one axial end of the first assembly 300 is connected to the drive mechanism 101 of the outer tube assembly 100, and the other axial end of the first assembly 300 is provided with an assembly part 301. The assembly part 301 is connected to the engaging part 501 of the inner tube 201. When the drive mechanism 101 is working, the drive mechanism 101 drives the first assembly 300 and the inner tube 201 to rotate synchronously, thereby causing the inner tube 201 to rotate inside the outer tube 102 of the outer tube assembly 100 to clean the clothes inside the inner tube 201.

[0064] Figure 8 shows a structural schematic diagram from another perspective of Figure 7. Combining Figure 7 and Figure 8, an assembly 302 is provided at the other axial end of the first assembly 300. The diameter of the assembly 302 is larger than the diameter of the other parts of the first assembly 300. The assembly 302 has an opening facing the other end of the first assembly 300 to form a first recess 303 at the end of the first assembly 300. At least a portion of the side wall of the assembly 302 is provided with a slot 304 (also referred to as a groove above) so that at least a portion of the inner wall of the first recess 303 is provided with a slot 304. Under the drive of the drive member 400, a plurality of engaging parts 501 expand and engage in the slot 304. The slot 304 is configured as the aforementioned assembly part 301. It should be noted that, in the embodiments of this disclosure, the fact that at least a portion of the side wall of the assembly part 302 is provided with a slot 304 means that: the side wall of the assembly part 301 is provided with an annular slot 304, that is, the slot 304 is arranged in an annular shape around the periphery of the side wall of the assembly part 301; or, the side wall of the assembly part 301 is provided with an arc-shaped slot 304, that is, the slot 304 is arranged in an arc shape around the periphery of the side wall of the assembly part 301.

[0065] Referring to Figures 7 and 8, in one embodiment, the mounting accessory 302 may be in the shape of a nut, and the mounting accessory 302 may be integrally formed with the rest of the first mounting part 300. In another embodiment, the mounting accessory 302 may also be cylindrical, square, or other structural forms, and this disclosure does not impose any limitations on this.

[0066] Figure 9 shows a structural schematic diagram of the inner tube 201 in Figure 3, and Figure 10 shows an exploded schematic diagram of Figure 9. Referring to Figures 9-11, according to an embodiment of this disclosure, the inner tube 201 includes a tube body 2011, and the garment handling device may include a mounting member 2012. The mounting member 2012 is connected to the outer side of the bottom of the tube body 2011, and multiple engaging portions 501 are disposed on the mounting member 2012. Exemplarily, the mounting member 2012 is a tripod.

[0067] Referring to Figures 9 and 10, in one embodiment, an installation recess 2013 is provided at the center of the bottom of the inner cylinder 201, and a plurality of positioning recesses 2014 are provided on the outer side of the bottom of the inner cylinder 2011. The plurality of positioning recesses 2014 can be spaced around the central axis of the inner cylinder 201, the inner ends of the plurality of positioning recesses 2014 extend to the installation recess 2013, and the outer ends of the plurality of recesses extend to the peripheral sidewall of the cylinder 2011.

[0068] Figure 11 shows a schematic diagram of the structure of the mounting component 2012 in Figure 10. Referring to Figures 9-11, the mounting component 2012 includes a mounting body 2015 and multiple connecting arms 2016. At least a portion of the mounting body 2015 is disposed in a mounting recess 2013. The multiple connecting arms 2016 are circumferentially spaced around the mounting body 2015 and each end is connected to the periphery of the mounting body 2015. The connecting arms 2016 are correspondingly disposed in the positioning recesses 2014. The connecting arms 2016 are disposed in the corresponding mounting recesses 2013. The end of the connecting arm 2016 away from the mounting body 2015 abuts against the side wall of the inner cylinder 201. The connecting arms 2016 are connected to the side wall of the cylinder 2011 by screws or other components, so as to fix the mounting component 2012 to the cylinder 2011 and improve the reliability of the assembly of the mounting component 2012 with the inner cylinder 2011. In another embodiment, the mounting body 2015 can also be directly assembled to the bottom of the inner cylinder 201's body 2011 using screws or other first fittings; this disclosure does not limit this. The mounting body 2015 or the entire mounting component 2012 can be configured as a second fitting 500.

[0069] Figure 12 shows a structural schematic diagram from another perspective of Figure 11. Referring to Figures 10 and 12, a mounting hole 2017 is provided at the center of the mounting recess 2013. The mounting body 2015 is provided with a first connecting sleeve 2018 inserted into the mounting hole 2017. The first connecting sleeve 2018 is axially continuous. A partition 2019 is provided inside the first connecting sleeve 2018. The partition 2019 has a first connecting hole 20110. Multiple engaging portions 501 are spaced apart on the side of the partition 2019 facing the drive mechanism 101. When not opened by the drive member, the multiple engaging portions 501 can slightly retract towards the central axis of the first connecting hole 20110. After the drive member 400 passes through the first connecting hole 20110 from the side of the partition 2019 facing away from the drive mechanism 101, the drive member 400 opens the multiple engaging portions 501, so that the multiple engaging portions 501 engage within the slots 304 of the mounting body 302. In practical implementation, the engaging portion 501 can be a relatively thin plate structure, giving it a certain degree of elasticity in the circumferential direction, i.e., the spring sheet described above. Thus, when the driving member enters the cavity formed by the multiple engaging portions, the multiple engaging portions can be opened, increasing the circumferential distance between them. After the driving member 400 is withdrawn from the multiple engaging portions 501, the multiple engaging portions 501 can return to their original position. The multiple engaging portions 501 can be integrally formed on the partition 2019.

[0070] Referring to Figure 12, according to one embodiment of this disclosure, a latch 502 is provided at one end of the engaging portion 501. When the engaging portion 501 is connected to the assembly portion, the latch 502 engages within the latch groove 304 to lock the engaging portion 501 and the assembly portion 301 together. In specific implementations, the latch 502 can be integrally formed with the engaging portion 501 to have sufficient strength.

[0071] Figure 13 shows an assembly diagram of the drive member 400 and the mounting member 2012 of the inner cylinder 201. Figure 14 shows an exploded view of Figure 13. Figure 15 shows a structural schematic diagram of the drive member 400 in Figure 13. Referring to Figures 13-15, according to an embodiment of this disclosure, a support protrusion 401 is provided on the periphery of the drive member 400. The support protrusion 401 can be an annular structure. After the drive member 400 passes through the first connecting hole 20110 of the first connecting sleeve 2018, the support protrusion 401 on the drive member 400 contacts a plurality of engaging portions 501 to open the plurality of engaging portions 501.

[0072] Referring to Figure 15, according to one embodiment of this disclosure, the head of the driving member 400 is provided with a guide portion 402. In one embodiment, the guide portion 402 is frustoconical to facilitate the insertion of the driving member 400 into the plurality of engaging portions 501. For example, the guide portion 402 is located on the side of the supporting protrusion 401 away from the inner cylinder and is connected to the supporting protrusion 401. For example, when the driving member 400 is assembled into the plurality of engaging portions 501, the guide portion 402 can partially or completely protrude from the inner cavity formed by the plurality of engaging portions 501. In other embodiments, the guide portion 402 may also be a spherical structure or a conical structure, and this disclosure does not limit this.

[0073] Figure 16 shows a structural schematic diagram from another perspective of Figure 13. Referring to Figures 6, 15, and 16, the drive component is detachably connected to the second assembly 500. After the user inserts the drive component 400 into the engaging portion 501, the drive component 400 connects to the second assembly 500, and the engaging portion 501 and the assembly portion 301 lock together. At this time, the limiting structure on the drive component 400 and the second assembly 500 restricts the drive component 400 to the position inserted into the engaging portion 501, ensuring that the drive component 400 does not disengage from the second assembly 500 when the inner cylinder 201 rotates. When it is necessary to disassemble and replace the inner cylinder 201, the user can release the limiting structure on the drive component 400 and the second assembly 500 to remove the drive component 400 from the engaging portion 501. At this time, the engaging portion 501 and the assembly portion 301 are no longer locked, and the inner cylinder 201 can be disassembled and replaced. The limiting structure on the drive component 400 and the second assembly 500 will be described below.

[0074] At least one of the first connecting sleeve 2018 and the driving member 400 has at least one positioning hole 20111 on its periphery, and the other has a positioning protrusion 403. The positioning protrusion 403 and the positioning hole 20111 are provided in a one-to-one correspondence, and the positioning protrusion 403 is detachably disposed in the corresponding positioning hole 20111. Figures 15 and 16 show the case where the first connecting sleeve 2018 has at least one positioning hole 20111 on its periphery, and the driving member 400 has a positioning protrusion 403 on its periphery. When the driving member 400 opens the multiple engaging parts 501, the positioning protrusion 403 is embedded in the corresponding positioning hole 20111 to prevent the driving member 400 from separating from the multiple engaging parts 501; when it is necessary to remove the driving member 400 from the multiple engaging parts 501, the positioning protrusion 403 is first separated from the corresponding positioning hole 20111, and then the driving member 400 is quickly removed from the multiple engaging parts 501. For example, both the positioning hole 20111 and the positioning protrusion 403 can be multiple, which can improve the reliability of the positioning protrusion 403 in the corresponding positioning hole 20111, thereby improving the support force of the drive mechanism 101 on the multiple engaging parts 501, preventing the multiple engaging parts 501 from disengaging from the assembly part 301 of the first assembly 300, and improving the reliability of the assembly of the inner cylinder 201 with the outer cylinder assembly.

[0075] Referring to Figures 15 and 16, according to an embodiment of this disclosure, a plurality of pressing members 404 are spaced apart on the periphery of the driving member 400. Positioning protrusions 403 and pressing members 404 are correspondingly arranged, with the positioning protrusions 403 connected to the corresponding pressing members 404. For example, the pressing members 404 have a certain elasticity. When a user presses the pressing member 404, it can be brought inward, thereby causing the positioning protrusions 403 on the pressing member 404 to separate from the corresponding positioning holes 20111. When the user releases the pressing member 404, the pressing member 404 returns to its original position. For example, the pressing member 404 is a plurality of elastic pieces disposed at the end of the driving member 400 away from the first mounting part 300 and arranged circumferentially on the driving member. For example, the drive member 400 is provided with an operating sleeve 408 circumferentially at one end away from the first assembly 300. The operating sleeve 408 is provided with a plurality of axially extending notches 405, and an elastic sheet is formed between two adjacent notches 405.

[0076] Referring to Figures 15 and 16, according to one embodiment of this disclosure, a pressing protrusion 406 is provided on the outer side of the pressing member 404 to facilitate the user applying force to the pressing member. Furthermore, along the axial direction of the driving member 400, the projection of the pressing protrusion 406 falls on the outer side of the first connecting sleeve 2018 to limit the assembly position of the pressing protrusion 406.

[0077] Referring to FIG15, according to an embodiment of the present disclosure, the driving member 400 includes an operating sleeve 408 and an operating lever 407. The operating sleeve 408 has an opening at one end facing the first assembly 300. The aforementioned pressing member 404 is disposed on the periphery of the operating sleeve 408. One end of the operating lever 407 is connected to the end of the operating sleeve 408, and the other end of the operating lever 407 protrudes from the opening of the operating sleeve 408. The aforementioned supporting protrusion 401 and guide portion 402 are disposed at the other end of the operating lever 407.

[0078] This embodiment of the present disclosure enables the quick disassembly of the engagement part 501 of the second assembly and the assembly part of the first assembly 300 by disassembling and assembling the multiple engagement parts 501 through the drive component 400, thereby realizing the disassembly and assembly of the inner drum 201 and the outer drum assembly 100. This facilitates the cleaning of the inner wall of the outer drum 102 and the inner and outer walls of the inner drum 201, improves the service life of the washing drum, avoids secondary pollution of clothes, avoids affecting user health, and improves user experience.

[0079] Based on the same design concept, this disclosure provides another assembly method for the first assembly 300, the driving member 400, and the inner cylinder 201. In this method, the engaging portions 501 are spaced apart circumferentially around the outer periphery of the assembly portion 301. In this embodiment, the driving member 400 can drive the multiple engaging portions 501 to retract, so that the multiple engaging portions 501 are connected to the assembly portion 301 of the first assembly 300, thereby connecting the inner cylinder 201 and the outer cylinder assembly 100; alternatively, the driving member 400 can also drive the multiple engaging portions 501 to expand, so that the multiple engaging portions 501 are separated from the assembly portion 301 of the first assembly 300, and the inner cylinder 201 is separated from the outer cylinder assembly 100.

[0080] For example, the first and second states are energized states; the driving member includes an electromagnet, which can control whether the engaging portion is pressed into the groove of the first assembly by applying an electrical signal to the electromagnet. For example, the engaging portion is made of magnetic material, and the electromagnet can directly act on the engaging portion to control whether the engaging portion is pressed into the groove of the first assembly; for example, the electromagnet can act on other components to control whether the engaging portion is pressed into the groove of the first assembly through the interaction of the other components with the engaging portion. The driving member switches between the first and second states to connect or separate multiple engaging portions from the assembly; in the first state, the driving member applies a radial locking force between the engaging portion and the assembly, connecting the engaging portion and the assembly; in the second state, the driving member releases the radial locking force between the engaging portion and the assembly, separating the engaging portion and the assembly. For example, in the first state, the electromagnet directly applies the locking force; or, in the first state, the electromagnet applies the locking force through other components included in the driving member.

[0081] For example, as shown in FIG23, the electromagnet 410 can be disposed at the bottom of the groove (i.e., the second recess) of the first assembly 300 or at a position close to the groove. When the electromagnet 410 is energized, the engaging portion 501 is pressed tightly in the groove of the first assembly; when the electromagnet 410 is de-energized, the engaging portion 501 is no longer pressed tightly in the groove of the first assembly 300. For example, the engaging portion 501 can be limited to a large space from the outer periphery of the engaging portion 501, so that the first assembly 300 has a large space to swing when the engaging portion 501 is no longer pressed tightly in the groove of the first assembly 300, so that the first assembly 300 and the second assembly 500 can be separated.

[0082] For example, the drive member 400 may further include a limiting portion 420, at least a portion of which is disposed along the outer periphery of the engaging portion 501, defining a limiting space 4201. When the engaging portion 501 is located in the limiting space 4201, the limiting portion 420 applies a radial locking force between the engaging portion and the assembly portion; when the electromagnet switches from the second state to the first state, the electromagnet drives at least a portion of the second assembly 500 and at least one of the limiting portion 420 to move, so that the engaging portion 501 leaves the limiting space 4201, and the limiting portion 420 no longer applies a radial locking force between the engaging portion 502 and the assembly portion. For example, at least a portion of the second assembly 500 is magnetic, and an electromagnet drives that portion of the second assembly to move, causing the engaging portion 501 to disengage from the limiting space 4201; or, at least a portion of the second assembly 500 and the limiting portion 420 are both magnetic, and the electromagnet drives the magnetic portion of the second assembly 500 and the limiting portion 420 to move in opposite directions, causing the engaging portion to disengage from the limiting space; or, the limiting portion is magnetic, and the electromagnet drives the limiting portion to move, causing the engaging portion to disengage from the limiting space. For example, the electromagnet is energized in the first state and de-energized in the second state. For example, the limiting portion is a cylindrical structure disposed on the outer periphery of the engaging portion 501.

[0083] Understandably, the portion of the limiting space 420 defined by the limiting part 420 needs to match the dimensions of the engaging part 501 and the assembly part 301. If the radial dimension of the limiting space 4201 is too large, the limiting part 420 cannot apply radial locking force between the engaging part and the assembly part when the engaging part 501 is located in the limiting space 4201.

[0084] As shown in the left figure of Figure 24, the limiting part 420 presses the engaging part 501 into the groove (hereinafter also referred to as the second recess) of the first assembly 300. As shown in the right figure of Figure 24, the electromagnet can be located to the right of the limiting part 420 (not shown in the figure). When the electromagnet is energized, the limiting part 420 moves to the right, and the limiting part 420 no longer presses the engaging part 501 into the groove of the first assembly. When the electromagnet is de-energized, the limiting part 420 moves forward back to its original position, and the limiting part 420 presses the engaging part 501 into the groove of the first assembly. It should be understood that the description here refers to the direction in Figure 24 and does not constitute a limitation on the direction in actual use.

[0085] Understandably, the shape and size of the electromagnet 410 and the limiting member 420 can be determined according to actual needs, and the installation position can be determined based on the feasibility of the device layout. For example, the electromagnet 410 can be installed in the outer cylinder to facilitate power supply to the electromagnet 410. For example, when the limiting member 420 is installed in the drive mechanism, the shape and size of the limiting member 420 can be designed according to the shape and size of the drive mechanism.

[0086] For example, the first assembly is a rod-shaped object, the mounting portion is a groove (hereinafter also referred to as the second recess) located near one end of the first assembly on its outer surface, and the engaging portion 501 is a ball. Multiple engaging portions 501 are spaced apart around the central axis of the first assembly. When the ball is pressed into the groove of the first assembly, that is, when the ball and the groove of the first assembly engage, the engaging portion and the mounting portion lock, and the first assembly and the second assembly are locked together. When the ball is no longer pressed into the groove of the first assembly, that is, when the ball and the groove of the first assembly no longer engage, the first assembly and the second assembly can be separated.

[0087] For example, the second assembly 500 includes a ball holder 506, which has an inner cavity 5061. The surface of the ball holder 506 is provided with multiple guide holes 5062 for limiting the engagement portion 501 of the ball in the axial direction of the inner cylinder. Each guide hole 5062 corresponds to a ball, which passes through the guide holes 5062. The lower part of the ball is located in the inner cavity 5061, and the upper part of the ball exits the guide holes 5062. The portion 5011 of the ball exiting the guide holes abuts against the inner wall of the limiting portion 420. For example, the ball holder 506 is magnetic. When the electromagnet switches from the second state to the first state, it drives the ball holder 506 to move along the axial direction of the inner cylinder, and moves the ball along the axial direction of the inner cylinder, causing the ball to leave the limiting space 4201.

[0088] Understandably, a through hole can be provided on one side of the limiting part and a through hole can be provided on one side of the ball retainer. The first assembly passes through the through hole on the limiting part and the through hole on the ball retainer into the inner cavity of the ball retainer.

[0089] For example, the drive member 400 further includes a pressing member 430, which includes an elastic member 4301. The elastic member 4301 applies a force to hold the engaging portion 501 in the limiting space 4201, ensuring that the engaging portion and the assembly portion are pressed together when the electromagnet is in the second state. For example, the pressing member 430 and the electromagnet 410 act on the same component, and the directions of the forces are opposite. For example, both the pressing member 430 and the electromagnet 410 act on the ball retainer 506. When the electromagnet 410 is in a de-energized state, the ball retainer 506 is held in the limiting space by the force of the pressing member; when the electromagnet switches from a de-energized state to an energized state, the ball retainer is subjected to the force of the pressing member and a magnetic force, and the magnetic force is greater than the pressing member force. The direction of the magnetic force is the direction that causes the ball retainer to leave the limiting space, and the ball retainer leaves the limiting space under the action of the magnetic force. For example, the elastic member 4301 is located in the inner cavity 5061 of the retainer. To apply a uniform force to the ball retainer 506, the pressing component may further include a pressing block 4302. One end of the elastic member 4301 is connected to the pressing block 4302, acting on the ball retainer 506 through the pressing block 4302. The other end of the elastic member 4301 abuts against components other than the pressing component 430. It is understood that the elastic member 4301 can abut in a suitable position to ensure that it can apply a force to hold the engaging portion in the limiting space. For example, the elastic member 4301 can abut against the bottom of the limiting portion or the bottom of the ball retainer. Exemplarily, the electromagnet can be positioned at the bottom of the limiting portion to make the drive component structure more compact.

[0090] For example, the limiting part 420 also includes a non-limiting space, the diameter of which is larger than the diameter of the limiting space 4201. When the electromagnet switches from the second energized state to the first energized state, it drives at least one of the second assembly and the limiting part to move, so that the engaging part leaves the limiting space and enters the non-limiting space. As mentioned above, the portion of the limiting space 4201 defined by the limiting part 420 needs to match the dimensions of the engaging part 501 and the assembly. If the radial dimension of the limiting space 4201 is too large, when the engaging part 501 is located in the limiting space 4201, the limiting part 420 cannot apply a radial locking force between the engaging part and the assembly. Therefore, limiting portions 420 with different cross-sectional diameters can be designed. When the engaging portion is located in a limiting portion with a cross-sectional diameter greater than a specific threshold, the limiting portion 420 applies a radial locking force between the engaging portion and the assembly portion, and the corresponding cross-section of the limiting portion corresponds to a limiting space. When the engaging portion is located in a limiting portion with a cross-sectional diameter less than or equal to the specific threshold, the limiting portion 420 cannot apply a radial locking force between the engaging portion and the assembly portion, and the corresponding cross-section of the limiting portion corresponds to a non-limiting space. It is understood that the limiting space and non-limiting space of the limiting portion are connected, and the engaging portion can move between the limiting space and the non-limiting space. When the electromagnet switches from the second energized state to the first energized state, it drives at least one of the second assembly and the limiting portion to move, so that the engaging portion leaves the limiting space 4201 and enters the non-limiting space.

[0091] For example, the first assembly is fixedly connected to the inner cylinder, and the second assembly is fixedly connected to the drive mechanism. For example, the end of the first assembly that does not pass through the inner cavity of the ball retainer is fixedly connected to the inner cylinder, and the second assembly is fixedly connected to the drive mechanism. The limiting part and the pressing part in the drive component are fixedly connected to the drive mechanism, and the electromagnet in the drive component is located on the outer cylinder. After the user gives a cylinder replacement command, the electromagnet switches from the second state to the first state, and the inner cylinder along with the first assembly can be disassembled by the user.

[0092] When the user pulls out the first assembly without giving a barrel replacement command, the direction of the force pulling out the first assembly is shown by the solid arrow in Figure 19B. This force compresses the ball radially outward, but due to the compression action of the elastic element 4301, the ball keeps pressing against the inner wall of the limiting part 420, and due to the effect of the limiting space, it forms a self-locking in the direction of the first assembly being pulled out, causing the first assembly to be unable to come out. After the user does not give a barrel replacement command, the electromagnet switches from the second state to the first state. The electromagnet generates a magnetic force to attract the ball holder to the bottom of the limiting part. At this time, the ball holder drives the ball from the limiting space to the non-limiting space. The non-limiting space is larger and cannot generate a self-locking, so the ball cannot press against the groove of the first assembly, and the first assembly can be smoothly removed, as shown in Figure 19C.

[0093] The accompanying drawings will now be used to further describe the specific details of another assembly method for realizing the first assembly 300, the drive component 400 and the inner cylinder 201.

[0094] Figure 17 shows an assembly diagram of the first assembly 300, the driving member 400, and the inner cylinder 201 in another embodiment. Figure 18 shows an exploded view of Figure 17, and Figure 19 shows a cross-sectional view of Figure 17. Referring to Figures 17-19, the first assembly 300 has a second recess 305 on its periphery, which is configured as an assembly part 301. Multiple engaging parts 501 of the second assembly 300 are spaced around the periphery of the second recess 305. Under the drive of the driving member 400, the multiple engaging parts 501 can retract into the second recess 305 to lock the multiple engaging parts 501 with the first assembly 300; or, the multiple engaging parts 501 can expand outward from the second recess 305 to unlock the multiple engaging parts 501 from the first assembly 300.

[0095] Referring to Figures 18 and 19A-C, the first assembly 300 is rod-shaped, the second assembly 500 includes a ball holder 506 and a ball 501, and the driving component 400 includes an electromagnet 410, a limiting part 420, an elastic element 4301, and a pressing block 4302. The limiting part 420 is cylindrical, having a first cylinder and a second cylinder connected together. The first cylinder generally forms the outer surface of a frustum, and the second cylinder is generally cylindrical, connected to the first cylinder at its maximum diameter. The ball holder 506 is located inside the cavity of the limiting part 420, and the shape of the ball holder 506 matches the shape and size of the cavity of the limiting part 420. The outer surface of the ball holder 506 is provided with a guide hole 5062.

[0096] The extrusion block 4302 divides the inner cavity 5601 of the ball holder into a first space 504 and a second space 505. The first assembly 300 can move through the second assembly 500 and enter the first space 504. The second recess 305 of the first assembly 300 is located in the first space 504. Multiple engaging parts 501 of the second assembly 500 are disposed in the first space 504 and are spaced apart around the second recess 305 of the first assembly 300. An electromagnet 410 is provided at the bottom of the limiting part 420. The two ends of the elastic member 4301 are connected to the electromagnet 410 and the extrusion block 4302, respectively. When the electromagnet 410 is not energized, the elastic member 4301 presses the engaging portion 501 toward the first assembly, thereby clamping the first assembly 300 with the multiple engaging portions 501, so that the first assembly 300 is locked inside the second assembly 500; when the electromagnet 410 is energized, the ball retainer 506 moves toward the electromagnet 410, and the ball retainer drives the multiple engaging portions 501 to move toward the second recess 305 away from the first assembly 300, so that the multiple engaging portions 501 release the first assembly 300, so that the first assembly 300 can be separated from the inside of the second assembly 500.

[0097] Figure 20 shows a schematic diagram of the drive component in Figure 19. Referring to Figures 20 and 24, in one embodiment, the limiting part 420 is a cylindrical structure with an opening at one axial end. An electromagnet 410 is assembled at the opening at one axial end of the limiting part 420, meaning the opening of the limiting part 420 is sealed by the electromagnet 410. Alternatively, the electromagnet 410 can be placed inside the limiting part 420, and one axial end of the limiting part 420 can also be sealed; this disclosure does not impose any limitations on this. The two ends of the elastic member 4301 are connected to the electromagnet 410 and the pressing block 4302, respectively. The other axial end of the limiting part 420 has a second connecting hole for the first assembly to pass through. The pressing block 4302 can be a plate-like structure or a cap-like structure.

[0098] Figure 21 shows a schematic diagram of the structure of the ball retainer 506 in Figure 18. The ball retainer 506 is provided in the limiting part 420 and is provided through the ball retainer 506 along its axial direction. At least part of the cross-section of the ball retainer 506 is gradually changing (called the variable diameter part, which is roughly a frustum structure and a hollow structure). The inner radial direction of the variable diameter part decreases away from the electromagnet 410. The second recess 305 of the first fitting 300 is provided in the variable diameter part of the ball retainer 506. Multiple engaging parts 501 are provided in the guide through holes of the variable diameter part of the ball retainer 506.

[0099] Referring to Figure 21, the circumference of the variable-diameter portion of the ball retainer 506 is provided with multiple guide holes 5062, and each guide hole corresponds to a locking portion 501. A portion of the locking portion 501 is placed within the guide hole 5062. The locking portion 501 can be a ball. As the multiple locking portions 501 move away from or towards the second recess 305 of the first assembly 300, a portion of the locking portion 501 remains within the guide hole. This guides the movement of the locking portions 501 and prevents them from failing to move along the predetermined path.

[0100] Figure 22 shows a schematic diagram of the structure of the compression block 4302 in Figure 18. Referring to Figure 22, according to an embodiment of this disclosure, the compression block 4302 has an opening at one end facing the electromagnet 410. One end of the elastic member 4301 abuts against the end face of the opening in the compression block 4302, and the other end of the compression block 4302 is connected to the electromagnet 410 to guide the compression deformation of the elastic member 4301. A through hole is provided on the end face of the opening for the first assembly part to pass through.

[0101] As can be seen from the above, the assembly method of the first assembly 300, the driving component 400 and the second assembly 500 in another embodiment provided by this disclosure only requires controlling the on and off of the electromagnet 410 to disassemble the first assembly and the second assembly 500, without the need for manual operation, and has good practicality.

[0102] In a specific implementation, the first assembly 300 is connected to the bottom of the inner drum 201, and the second assembly 500 is connected to the output shaft of the drive mechanism 101 of the garment processing equipment. In another embodiment, the first assembly 300 is connected to the output shaft of the drive mechanism 101, and the second assembly 500 is connected to the bottom of the inner drum 201, both of which enable quick disassembly of the inner drum 201.

[0103] It should be noted that, since the assembly method of the first assembly 300, the driving component 400 and the second assembly 500 in another embodiment does not require manual operation, only the on and off of the electromagnet 410 needs to be controlled, the connection structure constructed by the first assembly 300, the driving component 400 and the second assembly 500 can be provided in multiple ways. For example, multiple connections can be provided at axial intervals around the inner cylinder 201 to improve the reliability of the connection between the inner cylinder 201 and the output shaft of the driving mechanism 101.

[0104] The purpose of this disclosure is at least to some extent to enable the rapid removal of the inner drum from the garment handling equipment in order to clean the inner wall of the outer drum, as well as the inner and outer walls of the inner drum, thereby improving the service life of the washing drum and avoiding secondary contamination of the clothes.

[0105] The garment processing device provided in this disclosure can connect or separate the assembly parts of the second assembly and the first assembly by controlling the operation of the drive component. When the first assembly is connected to the inner tube, the second assembly is connected to the drive mechanism that drives the inner tube to rotate. By the operation of the drive component, the connection between the first assembly and the second assembly is cut off, and the inner tube can be quickly disassembled.

[0106] In addition, one of the first and second fittings is connected to the inner drum. When the first fitting is connected to the inner drum, the second fitting is connected to the drive mechanism that drives the inner drum to rotate. By actuating the drive mechanism, the connection between the first and second fittings is cut off, allowing the inner drum to be quickly disassembled to clean the inner wall of the outer drum, as well as the inner and outer walls of the inner drum. This improves the service life of the washing drum and avoids secondary pollution of clothes.

[0111] Although embodiments of the present disclosure have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present disclosure, the scope of which is defined by the claims and their equivalents.
