Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing processing technology, and in particular to a clothing processing device. Background Technology
[0002] A clothes dryer is a household appliance that uses electric heating to instantly evaporate the moisture from washed clothes. Current clothes dryers primarily use belt-driven and direct-drive methods. Belt-driven dryers connect the motor and drum via a belt, offering a simple structure and low cost. However, the belt wears easily and requires regular replacement, and belt-driven dryers also have low transmission efficiency and generate significant noise. Direct-drive dryers, on the other hand, drive the drum directly with the motor, eliminating the need for a belt. This results in high transmission efficiency, low energy consumption, and effectively avoids the noise generated by belt drives, making it widely used.
[0003] However, in existing direct-drive dryers, when the input shaft is connected to the inner drum, humid air inside the drum can easily enter the reducer through the connection between the input shaft and the inner drum, affecting the life of the reducer. In addition, lubricating grease in the reducer can also easily leak out through this point. Utility Model Content

[0041] As a specific embodiment of this utility model, such as Figures 1-4 As shown, this utility model provides a garment handling device, which may include: a cylindrical body 100, a rear support member 200, and a drive assembly 300. The cylindrical body 100 includes a garment inlet and a rear cover 110 at the opposite end of the garment inlet. The drive assembly 300 is detachably mounted on the rear support member 200, and its output end passes through one side of the rear support member 200 to the other side of the rear support member 200 to connect to the rear cover 110. A sealing structure 500 is formed between the output end and the rear support member 200.
[0042] Specifically, the garment processing device of this application embodiment includes a tubular body 100, a rear support member 200, and a drive assembly 300. The drive assembly 300 is detachably connected (e.g., screwed, riveted, etc.) to one side of the rear support member 200. The output end of the drive assembly 300 passes through the body of the rear support member 200 along the thickness direction to the other side and connects to the rear cover of the tubular body 100. By providing a sealing structure 500 at the connection between the output end and the rear support member 200, the sealing of the connection between the rear cover 110 of the tubular body 100 and the output end is ensured.
[0043] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the drive assembly 300 may include a direct drive motor 310 and a reducer 320. The direct drive motor 310 includes a stator assembly 311 and a rotor assembly 312. The reducer 320 is detachably connected to the stator assembly 311, and the stator assembly 311 is detachably connected to the rear support member 200 to connect the reducer 320 and the direct drive motor 310 to one side of the rear support member 200.
[0044] Specifically, the drive assembly 300 in this embodiment includes a direct drive motor 310 and a reducer 320. The direct drive motor 310 includes a stator assembly 311 and a rotor assembly 312. The rotor assembly 312 rotates relative to the stator assembly 311. The reducer 320 is detachably connected to the stator assembly 311, for example, by screwing or riveting. The input end of the reducer 320 is connected to the rotor assembly 312, and power is input to the reducer 320 through the rotor assembly 312. The stator assembly 311 is detachably connected to the rear support member 200, for example, by screwing or riveting. Thus, the reducer 320 and the direct drive motor 310 are mounted together on the rear support member 200. The output end of the reducer 320 passes through one side of the rear support member 200 to the other side of the rear support member 200 to connect to the rear cover 110 of the cylinder 100, thereby driving the rear cover 110 to rotate and drive the cylinder 100. It should be noted that the output end of the reducer 320 and the rear cover 110 can be detachably connected.
[0045] Therefore, the above connection method allows the cylinder 100, drive assembly 300 and rear support 200 in the garment processing device to be easily disassembled and installed, which facilitates maintenance and reduces costs.
[0046] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the reducer 320 may include: a housing 321, an input shaft 322 and an output shaft 323, and a planetary gear train 324. The input shaft 322 and the output shaft 323 are connected front to back, and are aligned in a straight line position by a bearing assembly 325 so as to be located inside the housing 321. The planetary gear train 324 is located inside the housing 321 and provides a driving connection between the input shaft 322 and the output shaft 323.
[0047] Specifically, in this embodiment, when the reducer 320 is running, the input shaft 322, as the main part of the sun gear, drives the planetary gear train 324 to rotate. The rotation of the planetary gear train 324 transmits torque to the output shaft 323, realizing the transformation of small torque transmission into large torque transmission. To improve the operating efficiency of the reducer 200, the input shaft 220 and the output shaft 230 operate independently, with torque transmission achieved by the planetary gear train 324. The output shaft 323 of the reducer 320 is connected to the rear cover 110 of the cylinder 100, enabling the cylinder 100 to rotate at a predetermined speed. The input shaft 322 and the output shaft 323 are aligned in a straight line position by a bearing assembly 325 located inside the housing 321. For example, coaxial bearings are provided at the connection points of the input shaft 322, the output shaft 323, and the housing 321 to support the input shaft 322 and the output shaft 323, thereby ensuring the efficiency of power transmission of the reducer 320.
[0048] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a through mounting hole 210 is formed between the two sides of the rear support member 200, and the output shaft 323 passes through the mounting hole 210 from one side of the rear support member 200 to the other side of the rear support member 200.
[0049] That is, by opening a through mounting hole 210 in the thickness direction of the rear support 200, the output shaft 323 passes through to connect to the rear cover 110.
[0050] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the sealing structure 500 may include a first groove 510 and a sealing ring 520. The first groove 510 is located on the other side of the rear support member 200 corresponding to the mounting hole 210. The portion of the output shaft 323 located on the other side of the rear support member 200 is placed in the first groove 510. The sealing ring 520 is located in the first groove 510 to seal the output shaft 323 and the mounting hole 210.
[0051] Specifically, the sealing structure 500 of this embodiment achieves a sealing effect by providing a first groove 510 on the other side of the rear support member 200 to accommodate the output shaft 323 passing through the mounting hole 210, and providing a sealing ring 520 in the first groove 510 to seal the mounting hole 210.
[0052] As a specific embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the sealing ring 520 is annular, and its cross-section in the radial direction is concave. The inner ring side of the sealing ring is inclined.
[0053] Specifically, in this embodiment, the cross-sectional opening of the sealing ring 520 faces the reducer 320 side, and its inner ring side is inclined to contact the outer surface of the output shaft 322, which can further improve the sealing effect.
[0054] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a first protrusion 220 is formed on the other side of the rear support member 200 corresponding to the mounting hole 210, and a first groove 510 is formed in the first protrusion 220.
[0055] Specifically, in this embodiment, the rear support member 200 is provided with a first protrusion 220 on its other side corresponding to the mounting hole 210, and a first groove 510 is provided in the first protrusion 220, which can effectively improve the structural strength of the rear support member 200 in the area of the first groove 510.
[0056] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the rear cover 110 is adapted to the first protrusion 220 and a second protrusion is formed at the corresponding position. The back of the second protrusion mates with the first protrusion 220 so that the rear cover 110 is detachably connected to one end of the output shaft 323 located on the side of the first groove 510.
[0057] In other words, the back cover 110 in this embodiment can play the role of mounting and positioning by providing a second protrusion at the corresponding position of the first protrusion 220 to cooperate with it.
[0058] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, one end of the output shaft 323 located on the side of the first groove 510 is connected to a flange 400, and the rear cover 110 is detachably connected to the output shaft 323 via the flange 400.
[0059] Specifically, the rear cover 110 of this application can be connected to the output shaft 323 by using a flange 400 configured to fit the shape of the first protrusion 220 (i.e., the flange becomes the second protrusion) to mount the rear cover 110 on the rear support 200.
[0060] As a specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a second groove 230 is formed on one side of the rear support member 200 corresponding to the mounting hole 210. The mounting hole 210 passes through the first groove 510 and the second groove 230. The housing 321 of the reducer 320 is located in the second groove 230.
[0061] Specifically, a second groove 230 is provided on the other side of the corresponding second groove 230 on the rear support member 200 to accommodate the reducer 320, and the direct drive motor 310 connected to the reducer 320 is also provided in the second groove 230, which can serve as a protective shell.
[0062] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
