Description

Technical Field

[0001] This application relates to the field of fabric treatment equipment technology, and more specifically, to a fabric treatment device. Background Technology

[0002] With the trend towards smaller living spaces and increased awareness of personal hygiene, the market demand for mini, partitioned, and hygienic washing machines is growing. Currently, multi-drum mini washing machines on the market mainly utilize two technological approaches:

[0003] Multi-motor independent drive: Each washing drum is equipped with an independent drive motor and control system. This approach results in high overall machine cost, complex structure, large size, and high energy consumption.

[0004] Single-motor switching drive: This approach attempts to use a single motor to switch between different washing drums via a complex clutch and pulley system. However, such systems typically only allow for time-sharing operation (when one drum is working, the others are stationary), and cannot enable simultaneous but independent washing of multiple drums in different modes. Furthermore, the mechanical structure remains complex, resulting in a high failure rate. Summary of the Invention

[0005] This application provides a fabric processing device. A main motor drives a main drive shaft, causing all drive components on the shaft to rotate synchronously. Multiple coiled shafts arranged around the shaft each have a corresponding driven component. A power coupling mechanism selectively engages or disengages between the main drive shaft and each coiled shaft, allowing a single main motor to simultaneously or sequentially output multiple speeds, directions, or neutral states. A controller independently regulates each power coupling mechanism, enabling synchronous operation of multiple coils in different operating modes. This eliminates the need for a multi-motor structure, simplifies the overall machine, reduces costs and size, while ensuring that each coil can be independently selected without interference, improving sorting efficiency and operational flexibility. Specifically:

[0006] The first aspect of this application provides a multi-tube fabric processing device, comprising:

[0007] Main motor;

[0008] The main drive shaft is driven by the main motor, and the main drive shaft is provided with multiple drive parts along the axial direction;

[0009] Multiple cylindrical shafts are arranged around the main drive shaft, and each cylindrical shaft is provided with multiple driven parts that correspond one-to-one with multiple drive parts;

[0010] A power coupling mechanism is provided between the main drive shaft and each cylinder shaft. The power coupling mechanism is used to selectively engage or disengage the corresponding drive part and driven part, so that the cylinder shaft can switch between at least two speeds, directions or neutral states.

[0011] The controller is used to independently regulate each power coupling mechanism to achieve different operating modes of multiple cylinders simultaneously or in shifts.

[0012] In the above technical solution, each driving part is composed of a driving gear set on the main driving shaft, and each driven part is a driven gear set on the cylindrical shaft. A radial clearance is left between the radially corresponding driving gear and driven gear, and they are in a non-meshing state.

[0013] The gears on the main drive shaft and the cylinder shaft are arranged axially with different pitch circle radii to form multiple gear pairs with different speed ratios and radial clearance dimensions.

[0014] The power coupling mechanism includes an axially movable shift fork and multiple intermediate gears fixed thereon. The number of intermediate gears is the same as the number of gear pairing groups and they correspond one-to-one.

[0015] By controlling the axial movement of the shift fork, the corresponding intermediate gear can be displaced between the driving gear and the driven gear of the corresponding gear pairing group, so as to transmit the driving force of the driving gear to the driven gear, thereby selectively connecting to the power path of the gear pairing group.

[0016] In the above technical solution, when a certain intermediate gear on the shift fork enters the corresponding gear pairing group, the intermediate gear directly meshes with the driving gear and driven gear of the same group at the same time, or indirectly meshes with the driving gear and / or driven gear through at least one transmission component, so as to transmit torque without changing the direction of rotation or changing the direction of rotation, so that the cylinder shaft obtains the corresponding speed and direction of rotation.

[0017] In the above technical solution, the transmission component is set as an idler wheel, and the idler wheel maintains constant mesh with the driven gear of the corresponding gear pairing group;

[0018] When the intermediate gear on the shift fork enters the gear pairing group, the intermediate gear simultaneously meshes with the drive gear and the idler gear, so as to transmit the torque of the main drive shaft in reverse to the corresponding cylinder shaft through the idler gear.

[0019] In the above technical solution, the pitch circle radius of the idler gear is smaller than the pitch circle radius of the intermediate gear it meshes with.

[0020] In the above technical solution, the multiple driving gears on the main drive shaft include a first driving gear, a second driving gear, and a third driving gear fixed in sequence along the axial direction, and the multiple driven gears on the cylindrical shaft include a first driven gear, a second driven gear, and a third driven gear fixed in corresponding order.

[0021] A first gear pairing group is formed between the first driving gear and the first driven gear, a second gear pairing group is formed between the second driving gear and the second driven gear, and a third gear pairing group is formed between the third driving gear and the third driven gear, wherein the third driven gear away from the bottom of the cylinder is constantly meshed with an idler gear;

[0022] The multiple intermediate gears on the shift fork include a first intermediate gear adapted to the first gear pairing group, a second intermediate gear adapted to the second gear pairing group, and a third gear pairing group adapted to the third intermediate gear.

[0023] The axial positioning of the shift fork allows for the selective engagement of the first, second, or third intermediate gear into the corresponding gear pairing group, thereby forming a three-stage gear pair with different output speeds.

[0024] In the above technical solution, when the first intermediate gear is connected to the first gear pairing group, a first-stage gear pair with the highest output speed is formed;

[0025] When the second intermediate gear is engaged in the second gear pairing group, a second-level gear pair with the second highest output speed is formed.

[0026] When the third intermediate gear is connected to the third gear pair, it forms a second-level gear pair with the lowest output speed.

[0027] In the above technical solution, the driving gear, driven gear, and intermediate gear are all helical gears.

[0028] In the above technical solution, the shift fork is driven by an actuator, which is selected from one of the following: motor-screw, motor-cam, or linear motor.

[0029] In the above technical solution, the fabric treatment section is a pulsator washing machine with multiple washing drums.

[0030] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0031] The fabric processing equipment in this embodiment drives the main drive shaft with a main motor, causing each drive part on the shaft to rotate synchronously. Multiple cylindrical shafts arranged around the shaft each have a corresponding driven part. The power coupling mechanism can selectively engage or disengage between the main drive shaft and each cylindrical shaft, allowing a single main motor to output multiple speeds, directions, or neutral states simultaneously or at different times. The controller independently regulates each power coupling mechanism to achieve synchronous operation of multiple cylindrical shafts in different operating modes, thereby eliminating the need for a multi-motor structure, simplifying the whole machine, reducing costs and size, while ensuring that each cylindrical shaft can be independently selected without interference, improving sorting and processing efficiency and usage flexibility.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0051] Addressing the core pain points of existing technologies—that multi-drum mini washing machines must employ multiple motors or complex clutch-belt systems, resulting in high costs, large size, high failure rates, and the inability to truly allow simultaneous independent washing of multiple drums—this paper proposes a solution of "single motor + multi-stage gears + axial shift fork gear selection." A multi-stage gear pairing group is set between the main drive shaft and each drum shaft. By axially moving the same shift fork, one can selectively engage different speed ratios or reverse gears with idlers, achieving full-function output of "multi-speed in the same direction + reverse + neutral." The controller uniformly schedules the positions of each shift fork and the speed of the main motor, allowing multiple drums to run different programs simultaneously while maintaining controllable peak total load. This concept aims to replace multiple motors and clutches with pure gear transmission, simplifying the structure, reducing size, lowering costs, and achieving "true synchronous multi-drum independent washing" within a miniature size for the first time, meeting market demands for categorized washing and care, energy saving, quiet operation, and high reliability.

[0052] Example

[0053] like Figures 1-4 As shown, the first aspect of this application provides a multi-tube fabric processing device, characterized in that it includes:

[0054] Main motor 10;

[0055] The main drive shaft 20 is driven by the main motor 10, and the main drive shaft is provided with multiple drive parts along the axial direction;

[0056] Multiple cylindrical shafts 30 are arranged around the main drive shaft 20, and each cylindrical shaft 30 is provided with multiple driven parts that correspond one-to-one with multiple drive parts.

[0057] A power coupling mechanism is provided between the main drive shaft 20 and each cylindrical shaft 30. The power coupling mechanism is used to selectively engage or disengage the corresponding drive part and driven part, so that the cylindrical shaft 30 can switch between at least two speeds, directions or neutral states.

[0058] The controller is used to independently regulate each power coupling mechanism to achieve different operating modes of multiple cylinders simultaneously or in shifts.

[0059] In this embodiment, the main motor 10 drives the main drive shaft 20, causing each drive part on the shaft to rotate synchronously. The multiple cylindrical shafts 30 arranged around the shaft each have a corresponding driven part. The power coupling mechanism can selectively engage or disengage between the main drive shaft 20 and each cylindrical shaft 30, allowing a single main motor to output multiple speeds, directions, or neutral states simultaneously or at different times. The controller independently regulates each power coupling mechanism to achieve synchronous operation of multiple cylinders in different operating modes, thereby eliminating the need for a multi-motor structure, simplifying the whole machine, reducing costs and size, while ensuring that each cylinder can be independently selected without interference, improving sorting efficiency and usage flexibility.

[0060] Furthermore, in some possible embodiments, each driving part is composed of a driving gear 201 disposed on the main driving shaft 20, and each driven part is a driven gear 301 disposed on the cylindrical shaft 30. A radial clearance is left between the radially corresponding driving gear 201 and driven gear 301, and they are in a non-meshing state.

[0061] The gears on the main drive shaft 20 and the cylindrical shaft 30 are arranged axially with different pitch circle radii to form multiple gear pairs with different speed ratios and radial clearance dimensions.

[0062] The power coupling mechanism includes an axially movable shift fork 40 and a plurality of intermediate gears 401 fixed thereon. The number of intermediate gears 401 is the same as the number of gear pairing groups and they correspond one-to-one.

[0063] By controlling the axial movement of the shift fork 40, the corresponding intermediate gear 401 can be displaced between the driving gear 201 and the driven gear 301 of the corresponding gear pairing group, so as to transmit the driving force of the driving gear 201 to the driven gear 301, thereby selectively connecting to the power path of the gear pairing group.

[0064] In this embodiment, each driving part and driven part is respectively set as a driving gear 201 on the main driving shaft 20 and a driven gear 301 on the cylindrical shaft 30. The radially corresponding driving gear 201 and driven gear 301 are kept in a non-meshing state with a radial clearance, thereby forming multiple gear pairs with different speed ratios and radial clearance sizes between the main driving shaft 20 and the cylindrical shaft 30. The power coupling mechanism adopts an axially movable shift fork 40 and multiple intermediate gears 401 fixed on it. The number of intermediate gears 401 and gear pairs is the same and they correspond one-to-one. By controlling the axial movement of the shift fork 40, the corresponding intermediate gear 401 can be moved to the driving gear 201 and driven gear 301 of the corresponding gear pair and establish meshing transmission. Thus, without adding an additional clutch or belt, a single motor can achieve independent speed ratio switching of multiple cylinders with a pure gear structure, simplifying the structure, improving transmission efficiency and reliability, and reducing noise and maintenance costs.

[0065] Furthermore, in some possible implementations, when an intermediate gear 401 on the shift fork 40 enters the corresponding gear pairing group, the intermediate gear 401 directly meshes with the driving gear 201 and driven gear 301 of the same group simultaneously, or indirectly meshes with the driving gear 201 and / or driven gear 301 through at least one transmission member, so as to transmit torque without changing the direction of rotation or by changing the direction of rotation, so that the cylinder shaft 30 obtains the corresponding speed and direction of rotation.

[0066] In this embodiment, the intermediate gear 401 is connected to the power path in two ways: "direct simultaneous engagement" or "indirect engagement via at least one transmission component". When directly engaged, the rotation of the main drive shaft 20 is transmitted to the drum shaft 30 in the same direction via the intermediate gear 401. When indirectly engaged via a transmission component (such as an idler wheel), the rotation direction is reversed. Thus, within the structure of the single set of shift forks 40 and the intermediate gear 401, both high-speed output in the same direction is retained, and a reverse gear is added. This enables multiple speed ratios and multiple steering options at the same axial position, significantly expanding the washing mode range of single-motor multi-drum equipment, improving the sorting and care capabilities and energy-saving effect. Furthermore, no additional clutch or belt is required, maintaining the high efficiency and long life of pure gear transmission.

[0067] Furthermore, in some possible embodiments, the transmission element is configured as an idler wheel 50, which is constantly engaged with the driven gear 301 of the corresponding gear pairing set;

[0068] When the intermediate gear 401 on the shift fork 40 enters the gear pairing group, the intermediate gear 401 simultaneously meshes with the drive gear 201 and the idler gear 50, so as to transmit the torque of the main drive shaft 20 in reverse to the corresponding cylinder shaft 30 through the idler gear 50.

[0069] In this embodiment, the transmission component is specifically configured as an idler gear 50 that is constantly meshed with the driven gear 301. When the shift fork 40 drives the intermediate gear 401 into the gear pairing group, the intermediate gear 401 simultaneously meshes with the driving gear 201 and the idler gear 50, so that the torque of the main drive shaft 20 is transmitted through the intermediate gear 401 → idler gear 50 → driven gear 301. The reverse action of the idler gear 50 is used to realize the reverse rotation of the drum shaft 30 relative to the main drive shaft 20, thereby reliably obtaining the reverse washing mode within a single gear structure, effectively reducing clothes tangling, improving the washing ratio, and eliminating the need for an additional motor or complex clutch, maintaining the high efficiency, low noise, and long life of pure gear transmission.

[0070] Furthermore, in some possible implementations, the pitch circle radius of the idler gear 50 is smaller than the pitch circle radius of the intermediate gear 401 with which it meshes.

[0071] Furthermore, in some possible embodiments, the plurality of driving gears 201 on the main drive shaft 20 include a first driving gear 2011, a second driving gear 2012 and a third driving gear 2013 fixedly along the axial direction, and the plurality of driven gears 301 on the cylindrical shaft 30 include a first driven gear 3011, a second driven gear 3012 and a third driven gear 3013 fixedly thereon. A first gear pairing group is formed between the first driving gear and the first driven gear, a second gear pairing group is formed between the second driving gear and the second driven gear, and a third gear pairing group is formed between the third driving gear and the third driven gear. The third driven gear 3013 away from the bottom side of the cylinder is constantly meshed with an idler gear 50.

[0072] The multiple intermediate gears on the shift fork 40 include a first intermediate gear 4011 adapted to the first gear pairing group, a second intermediate gear 4012 adapted to the second gear pairing group, and a third gear pairing group adapted to the third intermediate gear 4013.

[0073] The axial positioning of the shift fork 40 allows for the selective connection of the first, second, or third intermediate gear into the corresponding gear pairing group to form a three-stage gear pair with different output speeds.

[0074] In this embodiment, a three-layer gear pairing group is formed by sequentially fixing the first, second, and third driving gears axially on the main drive shaft 20 and correspondingly fixing the first, second, and third driven gears on the drum shaft 30. The shift fork 40 carries the first, second, and third intermediate gears and can be selectively connected to the corresponding pairing group axially. By utilizing the gear size differences of different pairing groups, the same shift fork can instantly complete three different speed ratio outputs within a pure gear structure, realizing independent speed-changing washing of multiple drums under single motor and single shift fork conditions. This significantly reduces the number of parts, shortens the axial dimension, and improves the efficiency and reliability of sorting and care.

[0075] Furthermore, in some possible implementations,

[0076] When the first intermediate gear is engaged in the first gear pairing group, a first-stage gear pair with the highest output speed is formed.

[0077] When the second intermediate gear is engaged in the second gear pairing group, a second-level gear pair with the second highest output speed is formed.

[0078] When the third intermediate gear is connected to the third gear pair, it forms a second-level gear pair with the lowest output speed.

[0079] In this embodiment, the single shift fork 40 can provide a clear graded "high-medium-low" speed output to the drum in one axial selection, realizing independent speed change washing of multiple drums under single motor drive, reducing repeated gear shifting actions, simplifying control logic, while maintaining the high efficiency and compact structure of pure gear transmission, and improving the efficiency and reliability of equipment classification and care.

[0080] Furthermore, in some possible implementations, the driving gear 201, driven gear 301, and intermediate gear 401 are all helical gears. It should be noted that the tooth surface of the helical gear is spiral, and the meshing process involves a gradual "line contact" across the entire tooth width, rather than the "sudden entry of the entire tooth" of a straight gear. When the shift fork drives the intermediate gear axially into the mating group, the helical tooth surface first achieves a "soft cut" through partial contact, and then gradually transitions to full-width bearing. This gradual meshing allows for a slight time difference in axial movement, preventing the tooth tip and tooth root from colliding hard at the same instant, thus effectively avoiding tooth collisions and impacts, ensuring smooth shifting, reducing impact noise, and extending gear life.

[0081] Furthermore, in some possible implementations, the shift fork 40 is driven by an actuator 60, which is selected from one of a motor-screw, a motor-cam, or a linear motor.

[0082] Furthermore, in some possible implementations, the fabric treatment area is a pulsator washing machine with multiple washing drums 70.

[0083] like Figures 1-4 As shown, the following is a detailed explanation of the operation process using a top-loading washing machine with four washing drums as an example of the fabric handling equipment:

[0084] User input: The user selects a program for each drum, such as: Drum 1 cotton and linen washing, Drum 2 silk washing, Drum 3 spin drying.

[0085] Program parsing: The main controller parses the program into specific shift fork position sequences and main motor commands.

[0086] Execution phase:

[0087] Washing: Drum 1 shift fork periodically switches between middle and lower positions {forward and reverse}; Drum 2 shift fork stays in the middle position {low speed forward rotation}; Drum 3 shift fork stays in neutral {paused}.

[0088] Spin-drying: After washing in drums one and two, the main controller first switches the fork of drum three to the upper position (high speed) for spin-drying; after spin-drying is completed, the spin-drying programs of drums one and two are then started.

[0089] Drying: The main controller starts the air duct and controls the forks of all the drums that need to be dried to switch between the middle position (low-speed forward rotation) and the lower position (reverse rotation) at a low frequency to achieve shaking and dispersing.

[0090] Example of a cotton and linen program:

[0091] Intensive Wash {Minutes 0-10}: The main controller controls the drum push rod motor, holding the shift fork in the "upper position {high speed forward rotation}" for 15 seconds, then switching to the "lower position {low speed reverse rotation}" and holding for 15 seconds, and so on. The main motor 10 runs at medium to high speed.

[0092] Rinse {10-15 minutes}: The shift fork is in the "neutral position {low speed forward rotation}" position, the main motor 10 is running at medium speed, forward rotation for 12 seconds, pause for 3 seconds.

[0093] Dehydration {15-18 minutes}: When the system schedules this drum for dehydration, the shift fork switches to "upper position {high speed forward rotation}" and the main motor 10 runs continuously in one direction at the highest speed for 3 minutes.

[0094] Throughout the process, each of the other washing drums can run its own program independently without interfering with the others. The spin-drying stage is centrally scheduled by the main controller to avoid simultaneous high-speed operation.

[0095] It should be noted that shifting gears using the shift fork should not be performed at high speeds.

[0096] Specifically, the washing machine operates at high speed during the spin cycle, so each drum spins at different times. If multiple drums are in the spin cycle at the same time, they can be switched to high speed simultaneously. However, the load on the main drive shaft 20 must not exceed the rated value. If overload is detected, the simultaneous spin cycle will stop, and each drum will spin in a staggered sequence.
