[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] In the description of the embodiments of the present application, it should be noted that the terms "front", "rear", "axial" and the like indicate directions or positional relationships based on the attached drawings. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating the description of the embodiments of the present application and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the embodiments of the present application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] An embodiment of the present application provides a clothes processing device, including a box body and a drum assembly 100, wherein the drum assembly 100 is arranged in the box body.

[0046] The box body is an exterior part of the clothes processing device. For example, the drum unit 100 is suspended in the box body through a suspension system, that is, the box body needs to bear the weight of the drum unit 100.

[0047] For example, see Figure 1 The barrel assembly 100 includes an outer barrel 2, an inner barrel assembly 1, a support shaft 3 and components arranged on the inner barrel assembly 1.

[0048] The inner drum assembly 1 has a laundry processing chamber 1b for placing laundry. A first end of the inner drum assembly 1 along the axial direction is open to form a laundry taking-in and putting-out opening 1a, through which a user can take laundry in and out.

[0049] Exemplarily, the inner barrel assembly 1 includes an inner barrel 11, which includes a barrel body 111 and a rear cover 112 arranged at the second axial end of the barrel body 111. The axial opposite ends of the barrel body 111 are open, the clothing taking and placing port 1a is located at the opening at the front end of the barrel body 111, and the rear cover 112 covers the opening at the rear end of the barrel body 111.

[0050] It is understood that the rear cover 112 may or may not be provided with through holes, and this is not a limitation. In the embodiment where the rear cover 112 is provided with through holes, air and / or water flow can be exchanged between the interior space of the inner tube 11 and the exterior space of the inner tube 11 through the through holes.

[0051] It should be noted that the inner drum 11 can be a perforated inner drum. In this embodiment, the inner drum 11 contains washing water through the outer barrel; the inner drum 11 can also be a non-perforated inner drum, that is, the inner drum 11 itself can contain washing water.

[0052] The type of clothing processing equipment is not limited, and it can be an integration of any one or more types of clothing processing equipment, such as a drum clothing processing equipment, a dryer, and a washer-dryer.

[0053] The outer tub 2 plays a role in installing and supporting the inner tub assembly 1. One end of the outer tub 2 close to the clothing access opening 1a is open, and the rear end of the outer tub 2 is provided with a tub bottom 21, which is a closed end.

[0054] See also Figure 5 The outer barrel 2 has an axial hole 2a. Specifically, the axial hole 2a is provided on the barrel bottom 21 and passes through the barrel bottom 21 along the front-to-back direction.

[0055] See also Figure 1 The support shaft 3 is inserted into the shaft hole 2a. The first axial end of the support shaft 3 is coaxially connected to the inner barrel assembly 1. In other words, the first axial end of the support shaft 3 is located inside the outer barrel 2. The rear end of the inner barrel assembly 1 is supported on the outer barrel 2 via the support shaft 3. It is understood that the front end of the inner barrel assembly 1 can be supported on the outer barrel 2 by rollers or the like.

[0056] See also Figure 2 , the second axial end of the support shaft 3 is located outside the outer barrel 2.

[0057] See also Figure 5 The support shaft 3 includes a first wire opening 3b at its first axial end, a second wire opening 3c on its circumferential surface at its second axial end, and a first wire passage 3a connecting the first and second wire openings 3b and 3c. In other words, the first wire opening 3b is located inside the outer tub 2, while the second wire opening 3c is located outside the outer tub 2.

[0058] The wiring harness 7 is electrically connected to the components and is routed through the first wire opening 3b, the first wire channel 3a, and the second wire opening 3c. In other words, one end of the wiring harness 7 is located inside the outer barrel 2, and the other end is located outside the outer barrel 2. The wiring harness 7 allows for electrical signal exchange and / or power transmission between the components on the inner barrel assembly 1 and other components outside the outer barrel 2.

[0059] The type of component is not limited and can be any device that requires electricity.

[0060] The number of cables included in the wiring harness 7 may be one or more.

[0061] It should be noted that the cables in the wiring harness 7 can be cables for transmitting electric energy or communication cables for transmitting communication signals.

[0062] In the barrel assembly 100 of the present embodiment, the wiring harness 7 is routed through the support shaft 3, preventing the wiring harness 7 from becoming entangled during the rotation of the inner barrel assembly 11, thereby facilitating the arrangement of components on the inner barrel assembly. Furthermore, the wiring harness 7 is routed from the circumferential surface of the second end of the support shaft 3, rather than from the axial end face 3d of the support shaft 3. This eliminates the need for the wiring harness 7 to occupy the space between the axial end face 3d of the support shaft 3 and the rear door of the housing. This allows for a smaller spacing between the axial end face 3d of the support shaft 3 and the rear door, reducing the housing's dimensions in the front-to-back direction. Furthermore, this prevents the rear door from abrading the wiring harness 7, thereby increasing the service life and reliability of the wiring harness 7.

[0063] For example, see Figure 1 、 Figure 2 as well as Figure 5 The drum assembly 100 includes a pulley 51, which is sleeved on the second end of the support shaft 3 and is fixedly engaged with the support shaft 3. The pulley 51 serves as the power input component of the drum assembly 100. For example, the laundry processing device is equipped with a motor and a belt. The power output shaft of the motor and the pulley 51 are driven by a belt. The belt drives the pulley 51 to rotate, and the pulley 51 drives the support shaft 3 to rotate. The support shaft 3 drives the inner drum assembly 1 to rotate within the outer drum 2.

[0064] There is no limit to the anti-rotation fit between the pulley 51 and the support shaft 3. For example, the part of the support shaft 3 used to fit with the pulley 51 is designed in the form of a flat shaft, see Figure 6 The assembly hole 51a on the pulley 51 is designed as a non-circular hole, and the flat shaft part of the support shaft 3 is inserted into the assembly hole 51a to achieve a non-rotational fit; for example, the pulley 51 and the support shaft 3 can achieve a non-rotational fit through the fit of a key and a keyway.

[0065] It should be noted that the axial positioning method of the pulley 51 on the support shaft 3 is not limited. For example, the axial positioning is achieved through an interference fit between the pulley 51 and the support shaft 3; for another example, the axial positioning is achieved through a retaining spring or the like.

[0066] For example, see Figure 1 and Figure 2 The barrel assembly 100 includes a locking nut 42 , which is sleeved on the support shaft 3 . The locking nut 42 is threadedly engaged with the support shaft 3 to directly or indirectly tighten the pulley 51 against the support shaft 3 , thereby achieving axial positioning of the pulley 51 .

[0067] The second wire-passing opening 3c can be provided at any appropriate position on the circumferential surface of the second axial end of the support shaft 3. For example, see Figure 2 The second wire opening 3c is located on the shaft section of the support shaft 3 on the side of the pulley 51 away from the outer barrel 2.

[0068] For example, in some embodiments, see Figure 2 The barrel assembly 100 includes a washer 41 , which is sleeved on the support shaft 3 . The washer 41 is sandwiched between the pulley 51 and the locking nut 42 . The locking nut 42 is pressed against the pulley 51 through the washer 41 .

[0069] See also Figure 7 and Figure 8 The circumferential surface of the bushing 41 is provided with a first wire hole 41a that communicates with the second wire opening 3c. The first wire hole 41a is substantially aligned with the second wire opening 3c, and the wiring harness 7 is passed through the first wire hole 41a. In other words, the wiring harness 7 is routed from the bushing 41. This embodiment ensures that the locking nut 42 is securely pressed against the pulley 51 while preventing the locking nut 42 from squeezing or abrading the wiring harness 7.

[0070] For example, see Figure 7 and Figure 8 The first wire passing hole 41a extends along the axial direction of the sleeve 41 and passes through at least the end face of the sleeve 41 along the axial direction. In this way, after the sleeve 41 is sleeved on the support shaft 3, the wiring harness 7 passed through the support shaft 3 can be inserted into the first wire passing hole 41a from the opening of the first wire passing hole 41a on the end face of the sleeve 41, which is convenient for quick wiring.

[0071] For example, see Figure 6 The drum assembly 100 includes an electrical device 52, which is mounted on the pulley 51. The electrical device 52 and the components are electrically connected via a wiring harness 7. Since there is no relative motion between the pulley 51 and the inner drum assembly 1, the electrical device 52 facilitates communication and / or power supply for the components disposed on the inner drum assembly 1. In addition, there is sufficient space on the pulley 51 for mounting the electrical device 52, making full use of the installation space on the pulley 51.

[0072] It should be noted that the specific type of the electrical device 52 is not limited, and it can be any device used to exchange electrical signals with components on the inner tube assembly 1.

[0073] It is understandable that the electrical device 52 is disposed on the side of the pulley 51 facing away from the outer tub 2 , so as to avoid interference between the electrical device 52 and the outer tub 2 during the rotation of the pulley 51 .

[0074] Exemplarily, the clothing processing device includes a main control board, which is used for overall control of the clothing processing device. The main control board and the electrical device 52 communicate wirelessly. The main control board sends control instructions to the electrical device 52, and the electrical device 52 controls the operation of components through cables.

[0075] Exemplarily, electrical device 52 includes a wireless charging receiver and an energy storage unit, the energy storage unit being electrically connected to the wireless charging receiver. The clothing processing device includes a wireless charging transmitter located on the rear door of the cabinet. The wireless charging transmitter generates an alternating magnetic field, and the wireless charging receiver senses the electromagnetic signal generated by the wireless charging transmitter and generates current through electromagnetic induction to charge the energy storage unit. The energy storage unit supplies power to the components via cables.

[0076] The first wire opening 3b can be provided at any appropriate position of the first axial end of the support shaft 3, and can be provided on the circumferential surface of the first axial end of the support shaft 3, or on the end surface of the first axial end.

[0077] For example, see Figure 3 and Figure 5 The first wire-passing opening 3b is provided on the end surface of the first end of the support shaft 3. The barrel assembly 100 includes a waterproof plug 8, which is sealedly inserted into the first wire-passing channel 3a through the first wire-passing opening 3b.

[0078] The waterproof plug 8 is made of elastic material, such as rubber, silicone, etc. The periphery of the waterproof plug 8 is sealed against the inner wall of the first wire channel 3a, and the washing water in the inner drum 11 basically does not penetrate between the waterproof plug 8 and the inner wall of the first wire channel 3a.

[0079] See also Figure 3 and Figure 10 The waterproof plug 8 has a second wire passage 8a extending axially through the waterproof plug 8, through which the wiring harness 7 passes in a sealed manner. In other words, the periphery of the wiring harness 7 and the inner wall of the second wire passage 8a are in sealed contact, and wash water within the inner drum 11 is substantially prevented from seeping between the periphery of the wiring harness 7 and the inner wall of the second wire passage 8a.

[0080] In this embodiment, the waterproof plug 8 can achieve a good sealing effect, preventing the washing water from leaking out of the outer tub 2 along the first wire passage 3 a of the support shaft 3 .

[0081] In some embodiments, the support shaft 3 is connected to the rear cover 112 . That is, in this embodiment, the inner barrel assembly 1 is not equipped with a balance frame 13 .

[0082] In other embodiments, please refer to Figure 5 、 Figure 9 、 Figure 10 as well as Figure 11 The inner cylinder assembly 1 includes a balancing frame 13, which is arranged on the rear side of the rear cover 112, and the first axial end of the support shaft 3 is connected to the balancing frame 13, that is, the inner cylinder assembly 1 is connected to the support shaft 3 through the balancing frame 13.

[0083] See also Figure 11The balance frame 13 is provided with a second wire hole 13 b that axially passes through the balance frame 13 . The wire harness 7 passes through the second wire hole 13 b and is led to the side of the balance frame 13 facing the rear cover 112 .

[0084] For example, see Figure 4 and Figure 9 The rear cover 112 and / or the balance frame 13 are provided with a third wire passage 13a extending radially along the inner cylinder 11. The wire harness 7 is passed through the second wire hole 13b and the third wire passage 13a. This facilitates routing and restraining the wire harness 7 through the rear cover 112 and / or the balance frame 13.

[0085] It should be noted that the rear cover 112 and / or the balancing frame 13 are provided with a third wire-passing channel 13a extending radially along the inner cylinder 11, including the following three embodiments: the first, the third wire-passing channel 13a is only provided on the side of the balancing frame 13 facing the rear cover 112; the second, the third wire-passing channel 13a is only provided on the side of the rear cover 112 facing the balancing frame 13; the third, a part of the third wire-passing channel 13a is located on the rear cover 112, and the other part is located on the balancing frame 13.

[0086] For example, see Figure 9 、 Figure 10 、 Figure 11 as well as Figure 12 The side of the balance frame 13 facing the rear cover 112 is partially recessed to define a third wire passage 13a. That is, in this embodiment, the third wire passage 13a is only provided on the side of the balance frame 13 facing the rear cover 112, thereby facilitating assembly and wiring. For example, during the manufacturing process, the balance frame 13 and the support shaft 3 can be first connected together, and the wiring harness 7 can be passed through the support shaft 3 and arranged in the third wire passage 13a of the balance frame 13. In other words, the wiring harness 7, the balance frame 13, and the support shaft 3 are integrated together to form a pre-assembled unit. On the assembly line, this pre-assembled unit can be assembled with the inner drum 11 and the outer drum 2. This simplifies the wiring time and wiring process on the assembly line.

[0087] For example, see Figure 4 、 Figure 5 as well as Figure 12 The balance frame 13 includes a plurality of limiting ribs 131 disposed within the third wire-passing channel 13a. The limiting ribs 131 are spaced apart along the extension direction of the third wire-passing channel 13a. The specific shape of the limiting ribs 131 is not limited, for example, a columnar shape, a sheet shape, etc., and is not limited here.

[0088] See also Figure 12One end of a limiting rib 131 is connected to one side wall of the third wire passage 13a, and the other end of the limiting rib 131 is spaced apart from the other side wall of the third wire passage 13a to define a latching opening 13c. The wiring harness 7 can be inserted into the third wire passage 13a through the latching opening 13c. After the wiring harness 7 is inserted into the third wire passage 13a through the latching opening 13c, the limiting rib 131, located on the open side of the wiring harness 7 facing the third wire passage 13a, constrains the wiring harness 7 to a certain extent, reducing the chance of the wiring harness 7 escaping from the third wire passage 13a.

[0089] For example, please refer to Figure 12 Along the length of the third wire-passing channel 13a, the corresponding snap-in openings 13c of each limiting rib 131 are staggered. Specifically, for ease of description, one side wall of the third wire-passing channel 13a is referred to as the first side wall, and the other side wall is referred to as the second side wall. Of any two adjacent limiting ribs 131, one limiting rib 131 is connected to the first side wall and spaced apart from the second side wall to form the aforementioned snap-in opening 13c; the other limiting rib 131 is connected to the second side wall and spaced apart from the first side wall to form the aforementioned snap-in opening 13c. In this way, the staggered distribution of the snap-in openings 13c corresponding to any two adjacent limiting ribs 131 can reduce the probability of the wire harness 7 escaping from the snap-in openings 13c.

[0090] For example, see Figure 4 、 Figure 5 as well as Figure 12 The balancing frame 13 includes a plurality of reinforcing ribs 132 arranged in the third wire-passing channel 13a. The reinforcing ribs 132 protrude from the bottom wall surface 13f of the third wire-passing channel 13a. The reinforcing ribs 132 can enhance the structural strength and rigidity of the balancing frame 13 at the third wire-passing channel 13a.

[0091] Multiple reinforcing ribs 132 are spaced apart along the extension of the third wire passage 13a. Each reinforcing rib 132 and each retaining rib 131 constrain the wire harness 7 between them. It should be noted that along the depth of the third wire passage 13a, i.e., along the axial direction of the inner barrel assembly 1, there is a certain spacing between the reinforcing ribs 132 and the retaining ribs 131 to facilitate clamping of the wire harness 7 and ensure that the wire harness 7 is routed in a generally straight line within the third wire passage 13a.

[0092] It can be understood that the distance between the reinforcing rib 132 and the limiting rib 131 is substantially equal to the outer diameter of the wire harness 7 , which will reduce the possibility of the wire harness 7 swinging.

[0093] For example, the first axial end of the inner cylinder 11 is provided with components, see Figure 9 、 Figure 13The wiring harness 7 includes a first wiring harness 7'. One end of the first wiring harness 7' is connected to the component located at the first axial end of the inner tube 11, and the other end of the first wiring harness 7' passes through the second wiring opening 3c. The first wiring harness 7' transmits electrical signals and / or power to the component located at the first axial end of the inner tube 11.

[0094] See also Figure 9 The first wire harness 7' includes a first sub-segment 71 and a second sub-segment 72 connected to each other. The first sub-segment 71 is arranged along the axial direction of the inner tube 11, and the second sub-segment 72 is arranged in the third wire passage 13a.

[0095] It should be noted that the first sub-section 71 may be arranged along the outer surface of the inner cylinder 11 , or may be arranged inside the inner cylinder 11 .

[0096] For example, see Figure 1 and Figure 5 The inner drum assembly 1 includes lifting ribs 14 disposed within the drum body 111. The first sub-segment 71 passes through the space within the lifting ribs 14 and is electrically connected to components located at the first axial end of the inner drum 11. The lifting ribs 14 protect and constrain the first sub-segment 71, thereby reducing the degree of wear on the first sub-segment 71 caused by high vibration and centrifugal force of the laundry processing device.

[0097] For example, see Figure 13 、 Figure 14 and Figure 15 In order to facilitate the restraint of the first sub-segment 71, at least one wire buckle 141 is provided in the lifting rib 14. The wire buckle 141 has a wire fixing groove 141a for accommodating the wire harness 7. The first sub-segment 71 is inserted into the wire fixing groove 141a to prevent the first sub-segment 71 from hitting the inner cylinder 11 and / or the lifting rib 14 when the inner cylinder 11 rotates at high speed, thereby causing wear of the first sub-segment 71 and also avoiding noise caused by hitting. In addition, the wire harness 7 can be fixed by placing it in the wire fixing groove 141a, which is simple and convenient to operate.

[0098] In one embodiment, referring to the figure, one side of the wire fixing groove 141a has a notch 141b for the wire harness 7 to be inserted into. The notch 141b is constructed so that when the wire harness 7 is inserted into the notch 141b, the notch 141b can be restorably stretched open by the wire harness 7.

[0099] Specifically, when fixing the wiring harness 7, the wiring harness 7 is passed through the slot 141b, the wiring harness 7 squeezes the wire buckle 141, and the wire buckle 141 produces a certain elastic deformation to expand the slot 141b. After the slot 141b is expanded, the wiring harness 7 passes through the slot 141b and is placed in the wire fixing groove 141a. The slot 141b returns to its original state. The slot 141b can block and limit the wiring harness 7 to reduce the chance of the wiring harness 7 falling out of the wire fixing groove 141a.

[0100] In one embodiment, please refer to Figure 15 At least two elastic arms 1411 are also provided within the lifting rib 14. One end of each elastic arm 1411 is connected to the wire clip 141, while the other end is free. The free ends of the two elastic arms 1411 are spaced apart to define a wire-engaging opening 141c for receiving the wire harness 7. The wire-engaging opening 141c is connected to the slot 141b, and the opening size of the wire-engaging opening 141c is smaller than the opening size of the slot 141b. In other words, when the wire harness 7 passes through the wire-engaging opening 141c, the free ends of the two elastic arms 1411 are stretched apart by the elastic force. After the wire harness 7 passes through the wire-engaging opening 141c, the free ends of the two elastic arms 1411 return to their original state, and the wire harness 7, having passed through the wire-engaging opening 141c, is then placed into the wire-fixing groove 141a through the slot 141b.

[0101] Since the opening size of the wire clamping opening 141c is smaller than the opening size of the slot 141b, the wire harness 7 can be blocked after it is accidentally loosened from the wire fixing slot 141a to prevent the loosened wire harness 7 from hitting the inner tube 11 and / or the lifting rib 14 and causing wear of the wire harness 7.

[0102] In one embodiment, please refer to Figure 15 The free ends of the two elastic arms 1411 are arranged obliquely toward the clamping direction of the wiring harness 7, and the distance H1 between the ends of the two elastic arms 1411 for connection with the wire buckle 141 is greater than the distance H2 between the free ends. When the wiring harness 7 is loosened from the wire fixing groove 141a due to an accident, the wiring harness 7 rests on the free ends of the two elastic arms 1411. Once the wiring harness 7 moves outward, it will squeeze the elastic arms 1411, forcing the two elastic arms 1411 to undergo elastic deformation outward, which will cause the distance between the free ends of the two elastic arms 1411 to become smaller and smaller, resulting in a smaller and smaller probability of the wiring harness 7 loosening from the gap between the free ends of the two elastic arms 1411.

[0103] For example, see Figure 14 There are multiple wire buckles 141, and the multiple wire buckles 141 are arranged at intervals along the axial direction of the barrel 111, thereby making the wire harness 7 more securely fixed.

[0104] It is understandable that in other embodiments, the elastic arm 1411 may not be provided.

[0105] For example, see Figure 10 、 Figure 11 as well as Figure 12 The balance frame 13 is provided with a third wire hole 13d that passes through the balance frame 13 in the axial direction; the second axial end of the inner cylinder 11 is provided with components, please refer to Figure 4 and Figure 9The wiring harness 7 includes a second wiring harness 7", one end of which passes through the second wire opening 3c, and the other end of the second wiring harness 7" passes through the third wire channel 13a and the third wire hole 13d, and is electrically connected to the components located at the second axial end of the inner tube 11. The second wiring harness 7" is led from the third wire hole 13d to the side of the balance frame 13 away from the rear cover 112, so that the second wiring harness 7" is easily connected to the components located at the second axial end of the inner tube 11.

[0106] The specific type of the component is not limited. For example, in an embodiment where the inner cylinder 11 is a non-porous inner cylinder, the component may be a dehydration valve provided on the inner cylinder 11 .

[0107] Exemplarily, the barrel assembly 100 includes a balancing device, see Figure 1 and Figure 13 The balancing device includes a balancing ring 6 connected to the inner cylinder 11 and a balancer disposed within the balancing ring 6. The balancing ring 6 is coaxially arranged with the inner cylinder 11 and moves synchronously with the inner cylinder 11. In other words, the balancing ring 6 is centered about the rotational centerline of the inner cylinder 11. The balancing ring 6 and the inner cylinder 11 can be fixedly connected by screws, snaps, welding, or other means, so that the balancing ring 6 rotates with the inner cylinder 11.

[0108] The components include conductive rails disposed on the gimbal 6, a wiring harness 7 electrically connected to the conductive rails, and a conductive contact portion configured on the balancer that maintains sliding and conductive contact with the conductive rails. The electrical device 52 communicates with the balancer via the wiring harness 7 to control the balancer's movement within the gimbal 6. In other words, the balancer's movement is controllable, rather than random.

[0109] When the inner drum 11 rotates at a high speed, for example, at a speed greater than 150 revolutions per minute, when the load in the inner drum 11 is eccentric, the inner drum 11 may rotate eccentrically. The electrical device 52 can control the balancer to move in the balance ring 6 to offset the eccentric mass of the inner drum 11 and suppress the eccentric amplitude of the inner drum 11, thereby reducing the vibration of the clothing processing equipment.

[0110] The balancing device can be provided at any position along the axial direction of the inner cylinder 11. For example, it can be provided at the first end along the axial direction of the inner cylinder 11, or at the second end along the axial direction of the inner cylinder 11, or at the middle position along the axial direction of the inner cylinder 11.
