[0012] Optionally, the reinforcing rib further includes a second annular rib, which is arranged inside the first annular rib. A plurality of strip ribs are provided between the first annular rib and the second annular rib. The plurality of strip ribs are arranged radially, and two adjacent strip ribs together with the first annular rib and the second annular rib form the mounting groove.

[0013] Optionally, the first annular rib is provided with a glue-blocking flange.

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, the directional terms "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. The directional terms "front" and "rear" refer to the direction closer to the cylinder opening and the direction further away from the cylinder opening in the axial direction of the cylinder body. Furthermore, the use of terms such as "first" and "second" is intended to distinguish different components and does not imply sequentiality or importance. In addition, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the present disclosure.

[0031] According to a specific embodiment of this disclosure, refer to Figures 1 to 5 As shown, a garment processing device is provided, comprising: a cylinder 1, the cylinder 1 including an outer cylinder 11 and an inner cylinder, the bottom wall 115 of the outer cylinder 11 being provided with a settling groove 111; and a motor 2, the motor 2 being used to drive the inner cylinder to rotate, at least a portion of the motor 2 being disposed in the settling groove 111.

[0032] Through the above technical solution, since the depth of the recess 111 of the bottom wall 115 of the outer cylinder 11 is part of the axial space of the cylinder 1, by partially placing the motor 2 within the recess 111, the motor 2 and the cylinder 1 can share a portion of the depth in the axial direction of the cylinder 1, that is, the motor 2 and the cylinder 1 can share a portion of the arrangement space. This reduces the space occupied by the motor 2 and the outer cylinder 11 in the axial direction of the cylinder 1, improving the overall compactness of the garment processing equipment. Thus, without changing the arrangement space of the garment processing equipment, the above arrangement helps to increase the volume of the cylinder 1, which is beneficial to meeting users' demand for large capacity in the cylinder 1.

[0033] In this context, the bottom wall 115 of the outer cylinder 11 refers to the wall surface of the bottom plate, which is positioned opposite the opening in the axial direction of the cylinder 1. The recessed groove 111 can be understood as the recessed area of ​​the outer cylinder 11 on the bottom wall 115. Additionally, the top end of the motor 2 refers to the end of the motor 2 near the cylinder opening, and the bottom end of the motor 2 refers to the end of the motor 2 away from the cylinder opening.

[0034] In some embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, the motor 2 includes a stator winding 21, which is at least partially disposed in a recess 111. This allows the portion of the stator winding 21 within the recess 111 to share a depth with the outer cylinder 1, meaning the stator winding 21 and the outer cylinder 1 can share a portion of their arrangement space. By reducing the axial space occupied by the stator winding 21 and the outer cylinder 11 in the outer cylinder 1, the axial space occupied by the motor 2 in the outer cylinder 1 is reduced, thereby increasing the volume of the garment processing equipment. Simultaneously, the bottom wall 115 of the outer cylinder 11 provides stable support for the stator winding 21, ensuring the reliability of the stator winding 21's fixation during motor operation. Furthermore, compared to placing the rotor 22 in the recess 111, this improves the ease of motor 2 assembly. Additionally, due to the large contact area between the outer cylinder 11 and the outside air, the heat from the stator winding 21 can be conducted to the air through the outer cylinder 11, which is beneficial for heat dissipation of the stator winding 21.

[0035] In some embodiments of this disclosure, reference is made to Figure 3 As shown, the stator winding 21 includes multiple coil groups 211, and the slot 111 includes multiple mounting slots 112, each mounting slot 112 accommodating at least one coil group 211. By placing multiple coil groups 211 in the mounting slots 112 respectively, the uniformity of the magnetic field distribution of the motor 2 is ensured, and the contact area between each coil group 211 and the air is increased, improving the heat dissipation effect of the stator winding 21 and preventing localized overheating. This extends the service life of the motor 2 and improves its reliability.

[0036] In some embodiments of this disclosure, reference is made to Figure 3As shown, multiple mounting slots 112 are arranged sequentially around the circumference of the outer cylinder 11, and the multiple mounting slots 112 are rotationally symmetrical. For example, the multiple mounting slots 112 are rotationally symmetrical about the central axis of the cylinder 1. In this way, the magnetic field distribution generated by the coil group 211 around the outer cylinder 11 can be more balanced, thereby reducing magnetic field distortion, ensuring the stability of the motor 2 operation and the uniformity of the output torque, reducing the vibration and noise generated during the operation of the motor 2, and improving the overall performance and operating quality of the motor 2.

[0037] In some embodiments of this disclosure, the mounting groove 112 is filled with a connecting adhesive, which is used to fix the coil assembly 211 in the mounting groove 112. This allows the coil assembly 211 to be fixed in the mounting groove 112 by the connecting adhesive, ensuring the reliability of the connection of the coil assembly 211 within the mounting groove 112. This prevents the coil from shifting or loosening due to vibration or other factors during motor 2 operation, thus affecting the stability of motor 2 operation. Furthermore, the connecting adhesive forms an insulating layer between the coil assembly 211 and the mounting groove 112, improving the safety of motor 2 operation. Simultaneously, the connecting adhesive also provides a seal for the gap between the mounting groove 112 and the coil assembly 211, preventing moisture, dust, etc., from entering and causing corrosion, short circuits, or other damage to the coil, thus ensuring the reliability of the internal structure and performance of motor 2.

[0038] In some embodiments of this disclosure, the connecting adhesive also coats the coil assembly 211. This further ensures the sealing performance of the coil assembly 211, and the strength and hardness of the cured connecting adhesive can support and protect the coil assembly 211, improve the mechanical strength of the coil assembly 211, increase its resistance to impact and vibration, and reduce the risk of damage to the coil assembly 211 during installation and transportation.

[0039] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 3 As shown, the bottom wall 115 of the outer cylinder 11 is provided with reinforcing ribs 113, which together with the bottom wall 115 form a recess 111. Thus, since the bottom wall 115 of the cylinder 1 is provided with reinforcing ribs 113 to enhance structural strength, and the motor 2 is mounted in the recess 111 formed by the reinforcing ribs 113 and the bottom wall 115, there is no need to separately process the recess 111, saving on the processing steps of the cylinder 1, improving production efficiency, and eliminating the need for additional recessed structures that would increase the thickness of the bottom wall 115 or occupy additional space, thus saving axial space in the cylinder 1.

[0040] In some embodiments of this disclosure, reference is made to Figure 3As shown, the reinforcing rib 113 includes a first annular rib 1131, the axis of which coincides with the axis of the cylinder 1. The first annular rib 1131 and the bottom wall 115 form a recessed groove 111. This allows the coil assembly 211 to be placed within the recessed groove 111, facilitating coaxial positioning of the coil assembly 211 and the cylinder 1. This prevents the stator winding 21 from being eccentrically installed, thus avoiding vibrations during motor 2 operation and improving the stability and reliability of motor 2 operation.

[0041] In some embodiments of this disclosure, reference is made to Figure 3 As shown, the reinforcing rib 113 also includes a second annular rib 1132, which is arranged inside the first annular rib 1131. Multiple strip ribs 1133 are arranged radially between the first annular rib 1131 and the second annular rib 1132. Adjacent strip ribs 1133, together with the first annular rib 1131 and the second annular rib 1132, form a mounting groove 112. Thus, the mounting groove 112 formed by the first annular rib 1131 and the second annular rib 1132 provides stable support for the coil assembly 211, allowing for fixation of the coil assembly 211 and preventing displacement of the coil assembly 211 during motor 2 operation, thus ensuring the reliability of the equipment. Meanwhile, the radial arrangement of the strip ribs 1133 helps increase the structural strength of the first annular rib 1131 and the second annular rib 1132, ensuring the connection strength of the coil group 211 within the mounting groove 112. Furthermore, the distribution of the strip ribs 1133 ensures the rotational symmetry of the mounting groove 112, guaranteeing the uniformity of the magnetic field distribution. Additionally, the radial arrangement of multiple strip ribs 1133 disperses the torque across the entire bottom wall 115, preventing torque concentration in a single area and thus improving the torsional resistance of the bottom wall 115 of the cylinder 1.

[0042] In some embodiments of this disclosure, reference is made to Figure 2 and Figure 3 As shown, a glue-blocking flange 114 is provided on the first annular rib 1131. In this way, when filling the mounting groove 112 with connecting adhesive, the glue-blocking flange 114 can limit the filling area of ​​the connecting adhesive, prevent the connecting adhesive from overflowing into the mounting groove 112 and causing waste, and help control the amount of connecting adhesive used, as well as keep the appearance of the motor 2 clean.

[0043] In some embodiments of this disclosure, reference is made to Figure 2As shown, the motor 2 includes a rotor 22, which is at least partially disposed in the settling tank 111. This allows the portion of the rotor 22 within the settling tank 111 to share a depth with the outer cylinder 1, meaning the rotor 22 and the outer cylinder 1 can share a portion of their arrangement space. This reduces the axial space occupied by the rotor 22 and the outer cylinder 11 within the cylinder 1, thereby reducing the axial space occupied by the motor 2 within the cylinder 1 and increasing the volume of the garment processing equipment. Furthermore, the stator winding 21 and a portion of the rotor 22 can be placed within the settling tank 111 to share a depth with the cylinder 1, fully utilizing the internal space of the cylinder 1 and further improving the volume and space utilization of the garment processing equipment.

[0044] In some embodiments of this disclosure, reference is made to the figures. Figure 2 and 4 As shown, the rotor 22 is constructed as a disc rotor, comprising a plurality of magnets 221 arranged circumferentially. The magnets 221 and the stator windings 21 are arranged sequentially along the axial direction of the cylinder 1, with the thickness direction of the magnets 221 aligned along the axial direction of the cylinder 1. This disc rotor 22 is constructed in a flat shape to accommodate the shape of the sink 111 and the distribution of the coil group 211. Furthermore, the thickness direction of the magnets 221 is arranged along the axial direction of the cylinder 1 to reduce the space occupied by the rotor 22 in the axial direction, allowing the rotor 22 to be constructed as a flat, thin disc. This facilitates partial embedding of the rotor 22 into the sink and reduces the axial space occupied by the rotor 22 in the cylinder 1, thereby reducing the space occupied by the motor 2 and improving the space utilization rate inside the garment processing equipment.

[0045] When the coil group 211 is energized to generate a magnetic field, the coil group 211 can effectively correspond to and interact with the magnet 221 to drive the rotor 22 to rotate. During the rotation, the magnet 221 can also maintain correspondence with the coil group 211 to continuously generate a magnetic field and improve the electromagnetic conversion efficiency of the motor 2.

[0046] In some embodiments of this disclosure, reference is made to Figure 5 As shown, the rotor 22 includes a plurality of magnets 221 arranged circumferentially. The magnets 221 and the stator winding 21 are arranged sequentially in the radial direction of the cylinder 1, with the thickness direction of the magnets 221 arranged in the radial direction of the cylinder 1. In this way, the magnets 221 can be arranged in the radial direction of the stator winding 21, thereby reducing the space occupied by the rotor 22 in the radial direction and thus reducing the space occupied by the motor 2 in the axial direction of the cylinder 1.

[0047] By placing the stator winding 21 in the slot 111, and employing a disc rotor 22 and magnets 221, the resulting disc-type coreless motor 2 can generate a sufficiently strong magnetic field without an iron core, enabling normal operation of the motor 2. This allows the coil assembly 211 to fit into the mounting slot 112, reducing the space and mechanical strength requirements for the stator winding 21's installation location, facilitating flexible layout and installation, increasing the volume of the garment processing equipment, and reducing heat generated by iron core losses, further lowering the overall temperature of the motor 2, as well as reducing eddy current losses and hysteresis losses in the iron core, thus improving the operating efficiency of the motor 2.

[0048] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the bottom end of the motor extends out of the bottom wall 115, and the distance between the bottom end of the motor 2 and the bottom wall 115 is 35mm to 45mm. The distance between the bottom end of the motor 2 and the bottom wall 115 is D1. For example, D1 can be 35mm, 36mm, 37mm, etc., and this disclosure does not impose specific limitations on this. In this way, compared to suspending the motor 2 on the bottom wall 115, the distance between the bottom end of the motor 2 and the bottom wall 115 of the cylinder 1 can be reduced, thereby reducing the space occupied by the motor 2.

[0049] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the garment processing equipment includes a housing 10, in which a cylinder 1 and a motor 2 are disposed. The housing 10 includes a rear plate 101, and the distance between the bottom end of the motor 2 and the rear plate 101 is 15mm to 25mm. The distance between the bottom end of the motor 2 and the rear plate 101 of the housing 10 is D2. For example, D2 can be 15mm, 16mm, 17mm, etc., and this disclosure does not impose specific limitations on this. In this way, compared to suspending the motor 2 on the bottom wall 115, the distance between the bottom end of the motor 2 and the rear plate 101 of the housing 10 can be increased, thereby increasing the rear space of the cylinder 1 in the axial direction and improving the space utilization rate of the equipment.

[0050] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0052] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
