Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and in particular provides a clothing processing device. Background Art

[0002] With the development and progress of science and technology, people's functional demands for clothing processing equipment are becoming more and more diversified.

[0003] When a clothing processing device processes clothing, it is often necessary to obtain the clothing processing status in the inner drum in real time through various electrical devices to achieve better processing effects. In order to obtain the clothing processing status in the inner drum, the electrical devices need to be set on the inner drum. However, since the inner drum rotates, wiring between the electrical devices and the power supply is difficult.

[0004] Although a non-wiring solution between the inner cylinder and the shell can be used to ensure that the electrical device can work, such as electromagnetic induction, the inner cylinder is rotating, which usually leads to low induction efficiency and poor power-on effect.

[0005] Accordingly, the art needs a new clothes processing device to solve the above problems. Summary of the invention

[0006] The present invention aims to solve the above technical problem, that is, to solve the problem of poor power-on effect of the electrical device on the inner drum of the clothes processing equipment in the prior art.

[0007] The present invention provides a clothing processing device, which comprises: an inner drum, which is rotatable; an electrical component, which is arranged to rotate with the inner drum; and a power supply component, which comprises a transmitting coil and a receiving coil, wherein the transmitting coil is fixedly arranged and the receiving coil is installed on the inner drum, the conducting wire of the transmitting coil is folded and wound, and the receiving coil is electrically connected to the electrical component.

[0008] When the above technical solution is adopted, the power supply component is used to provide electric energy to the electric components on the inner cylinder to ensure the normal operation of the electric components. The power supply component generates a magnetic field after being energized by the transmitting coil, and the receiving coil generates current due to electromagnetic induction to provide electric energy to the electric components. The conducting wire of the transmitting coil is wound back and forth, so that the magnetic flux lines generated by the transmitting coil can be controlled within a specific area, such as a ring area, a C-shaped area, etc., that is, the magnetic flux lines can be concentrated instead of being dispersed to the periphery, so that the arrangement area of ​​the magnetic flux lines can be controlled according to the shape and rotation path of the receiving coil, that is, the receiving coil can be set in the magnetic flux line concentration area, thereby improving the inductive efficiency between the receiving coil and the transmitting coil, and thus improving the power-on effect of the electric device.

[0009] In a specific embodiment of the above-mentioned clothing processing device, the transmitting coil is a C-shaped ring, and the C-shaped ring is formed by winding the conducting wire of the transmitting coil from the outside to the inside in sequence, and the transmitting coil is coaxial with the rotating axis of the inner drum; the receiving coil is eccentrically arranged with the transmitting coil, and part or all of the receiving coil is arranged within the coverage range of the C-shaped ring.

[0010] In the case of adopting the above technical solution, the transmitting coil is a C-shaped ring obtained by winding the conductive wire back and forth. After the conductive wire is energized, the generated magnetic flux lines cover the entire annular area of ​​the C-shaped ring. Since part or all of the receiving coil is arranged within the coverage range of the C-shaped ring, when the receiving coil rotates with the inner cylinder, even if the position and / or shape of the transmitting coil and / or the receiving coil deviates, the transmitting coil can maintain continuous induction, thereby avoiding intermittent power supply and improving the induction effect of the receiving coil. In addition, since the transmitting coil is coaxial with the rotating shaft of the inner cylinder and the magnetic flux lines cover the entire annular area of ​​the C-shaped ring, the electromagnetic interference of the rotating shaft on the transmitting coil is reduced, and the receiving coil is eccentrically arranged with the transmitting coil, which also reduces the electromagnetic interference of the rotating shaft on the receiving coil, further improving the induction efficiency and improving the power-on effect of the electrical device.

[0011] In a specific embodiment of the above-mentioned clothing processing device, the transmitting coil includes a first wire and a second wire, the first wire is folded back and wound from the outside to the inside to form a first C-shaped structure including an inner ring and an outer ring, the second wire is connected to the end of the inner ring and is folded back and wound between the inner ring and the outer ring to form a second C-shaped structure, the transmitting coil is coaxial with the rotating axis of the inner cylinder; the receiving coil is eccentrically arranged with the transmitting coil, and part or all of the receiving coil is arranged within the coverage range of the second C-shaped structure.

[0012] When the above technical solution is adopted, since the magnetic flux lines generated by the first C-shaped structure are within the first C-shaped structure area, and the magnetic flux lines generated by the second C-shaped structure are within the second C-shaped structure area, the magnetic flux lines density within the second C-shaped structure area is the largest, and part or all of the receiving coil is arranged within the coverage range of the second C-shaped structure. Therefore, when the receiving coil rotates with the inner cylinder, it is in the area with the largest magnetic flux lines density most of the time, so that the induction effect is better; in addition, since the transmitting coil and the rotating shaft of the inner cylinder are coaxial and the magnetic flux lines are concentrated in the second C-shaped structure area, the electromagnetic interference of the rotating shaft on the transmitting coil is reduced, and the receiving coil is eccentrically arranged with the transmitting coil, which also reduces the electromagnetic interference of the rotating shaft on the receiving coil, further improving the induction efficiency and improving the power-on effect of the electrical device.

[0013] In a specific embodiment of the above-mentioned clothes processing device, the wire of the receiving coil is spirally arranged.

[0014] When the above technical solution is adopted, the spiral arrangement of the wire of the receiving coil can simplify the winding process and effectively reduce the production cost.

[0015] In a specific implementation of the above-mentioned clothes processing device, the transmitting coil is installed on the inner side of the rear shell of the clothes processing device, and the receiving coil is installed on the outer side of the rear wall of the inner drum.

[0016] When the above technical solution is adopted, the arrangement positions of the transmitting coil and the receiving coil can effectively utilize the space outside the rear wall of the inner tube and inside the rear shell. In addition, the close position of the transmitting coil and the receiving coil facilitates efficient induction of the receiving coil.

[0017] In a specific embodiment of the above-mentioned clothes processing device, a shielding layer is provided between the transmitting coil and the rear shell; and / or a shielding layer is provided between the receiving coil and the rear wall.

[0018] When the above technical solution is adopted, the provision of the shielding layer avoids electromagnetic interference and improves the inductive efficiency and safety.

[0019] In a specific embodiment of the above-mentioned clothing processing equipment, the electrical components include a dryness sensor and a signal transmitting module. The dryness sensor is installed in the inner drum. The dryness sensor is used to detect the dryness of the clothes. The signal transmitting module is configured to rotate with the inner drum and is communicatively connected with the dryness sensor.

[0020] When the above technical solution is adopted, the dryness sensor is directly arranged in the inner drum and can contact the clothes at a close distance, so as to achieve more accurate detection of the dryness of the clothes, especially when a large amount of clothes need to be dried or the distance between the clothes is far, and it does not affect the detection result; the signal transmission module is used to transmit the detection result of the dryness sensor, and the controller controls the operation of related programs according to the detection result after receiving the detection result.

[0022] When the above technical solution is adopted, the sensing element is used to sense the moisture change information in the inner drum, and the dryness determination chip is used to process the information sensed by the sensing element and convert it into the dryness of the clothes; since the lifting ribs rotate with the inner drum and the contact between the lifting ribs and the clothes is more frequent and close, the sensing element is directly arranged on the lifting ribs, which can contact the clothes at a close distance and for a long time, thereby further improving the detection accuracy of the dryness of the clothes; in addition, the lifting ribs also provide protection for the dryness determination chip, achieving the purpose of waterproofing, dustproofing and bump-proofing.

[0023] In a specific embodiment of the above-mentioned clothing processing device, the power supply component also includes a power storage module, which is arranged inside the lifting ribs and is electrically connected to the receiving coil, the dryness determination chip, and the signal transmission module respectively.

[0024] When the above technical solution is adopted, the power storage module is used to store the electric energy generated by the receiving coil, and serves as a backup power source to provide electric energy for the dryness determination sensor, signal transmission module and other electrical devices on the inner cylinder.

[0025] In a specific implementation of the above-mentioned clothing processing device, the clothing processing device further includes a signal receiving module, and the signal receiving module is fixedly arranged and communicatively connected with the signal transmitting module.

[0026] When the above technical solution is adopted, the signal receiving module is used to receive the detection information sent by the signal transmitting module and transmit it to the controller. The controller controls the clothing processing equipment to make corresponding responses and / or send reminder information to the user according to the detection results of the dryness sensor.

[0037] Based on the problem of poor energization effect of the electrical device on the inner drum of the clothing processing equipment pointed out in the background technology, the present invention provides a clothing processing equipment, which aims to control the magnetic flux lines generated by the transmitting coil within a specific area by folding the conductive wire of the transmitting coil, thereby controlling the arrangement area of ​​the magnetic flux lines according to the shape and rotation path of the receiving coil, thereby improving the inductive efficiency between the receiving coil and the transmitting coil, and further improving the energization effect of the electrical device.

[0038] The clothing processing device of the present invention may be a washing machine, a washer-dryer, a clothes dryer, a drying machine, or the like that can dry clothing, and no specific limitation is made herein.

[0039] See first Figure 1, which shows the cross-sectional structure of the clothes processing device of the present invention, the clothes processing device comprises an inner drum 1, electrical components, and power supply components. The inner drum 1 is provided with a rotating shaft 11, the output shaft of the motor is in transmission connection with the rotating shaft 11 and drives the inner drum 1 to rotate by driving the rotating shaft 11 to rotate, and the clothes to be processed are placed in the inner drum 1; the electrical components are arranged to rotate with the inner drum 1; the power supply components comprise a transmitting coil 2 and a receiving coil 3, the transmitting coil 2 is fixedly arranged, the receiving coil 3 is installed on the inner drum 1, the wire of the transmitting coil 2 is folded back and wound, the receiving coil 3 is electrically connected to the electrical components, and the power supply components are used to provide electricity to the electrical components on the inner drum 1 The power supply component generates a magnetic field after the transmitting coil 2 is energized, and the receiving coil 3 generates a current due to electromagnetic induction to provide electrical energy for the electrical components. The conducting wire of the transmitting coil 2 is wound back and forth, so that the magnetic flux lines generated by the transmitting coil 2 can be controlled within a specific area, such as a ring area, a C-shaped area, etc., that is, the magnetic flux lines can be concentrated instead of being dispersed to the periphery, so that the arrangement area of ​​the magnetic flux lines can be controlled according to the shape and rotation path of the receiving coil 3, that is, the receiving coil 3 can be arranged in the magnetic flux line concentration area, thereby improving the inductive efficiency between the receiving coil 3 and the transmitting coil 2, and further improving the power-on effect of the electrical device.

[0040] Specifically, the electrical components include a dryness sensor and a signal transmitting module. The dryness sensor is installed in the inner drum 1. The dryness sensor is used to detect the dryness of clothes. The signal transmitting module is configured to rotate with the inner drum 1 and is communicatively connected with the dryness sensor. The dryness sensor is directly arranged in the inner drum 1 and can contact the clothes at a close distance, thereby achieving more accurate detection of the dryness of clothes, especially when a large amount of clothes needs to be dried or the distance between clothes is far, and the detection result is not affected. The signal transmitting module is used to transmit the detection result of the dryness sensor. After receiving the detection result, the controller controls the operation of related programs according to the detection result.

[0041] Those skilled in the art will appreciate that, in addition to the dryness sensor and the signal transmission module, the electrical components may also include a lighting fixture or other electrical devices, and the lighting fixture is used to facilitate the operator to observe the laundry processing status in the inner drum 1 without opening the door.

[0042] Continue reading Figure 1The dryness sensor includes a sensing element 6 and a dryness chip connected to the sensing element 6, the dryness chip is communicatively connected to the signal transmitting module, the sensing element 6 is mounted on the outer wall of the lifting rib 12 in the inner drum 1, and the dryness chip is arranged inside the lifting rib 12; the sensing element 6 is used to sense the moisture change information in the inner drum 1, and the dryness chip is used to process the information sensed by the sensing element 6 and convert it into the dryness of the clothes; since the lifting rib 12 rotates with the inner drum 1 and the contact between the lifting rib 12 and the clothes is more frequent and close, the sensing element 6 is directly arranged on the lifting rib 12, and can contact the clothes at a close distance and for a long time, thereby further improving the detection accuracy of the dryness of the clothes; in addition, the lifting rib 12 also provides protection for the dryness chip, achieving the purpose of waterproofing, dustproofing and bump-proofing.

[0043] Possibly, the dryness determination chip is connected to the sensing element 6 via a signal line, and the signal line is arranged through the lifting rib 12. A sealing structure such as a sealing ring, a sealant, etc. is arranged between the signal line and the lifting rib 12. A sealing structure such as a sealing gasket, a sealant, etc. is also arranged between the lifting rib 12 and the inner tube 1 to ensure the sealing of the space inside the lifting rib 12 and prevent water in the inner tube 1 from entering the lifting rib 12, thereby ensuring the normal use of the dryness determination chip and other devices in the lifting rib 12.

[0044] Optionally, the sensing element 6 is a metal sheet, which can form an electrostatic field with the inner tube 1 and sense the change of the electrostatic field; a socket is provided on the lifting rib 12, and the end of the metal sheet is bent and plugged and fixed with the socket, which is convenient for the disassembly, maintenance and replacement of the sensing element 6. It should be noted that the bending structure of the metal sheet can be provided with multiple, and the corresponding sockets are also provided with a number corresponding to the bending structure, which is used to achieve a more secure installation. In addition, in addition to being plugged and fixed on the outer wall of the lifting rib 12, the sensing element 6 can also be fixed on the outer wall of the lifting rib 12 by integral injection molding, or can be installed on the outer wall of the lifting rib 12 by bolt installation or bonding installation. Those skilled in the art can make adjustments as needed, and these adjustments do not deviate from the principles of the present invention and are within the scope of protection of the present invention. Accordingly, the lifting rib 12 can be an insulating material such as plastic, or a non-insulating material. If the lifting rib 12 is a non-insulating material, an insulating layer needs to be provided between the metal sheet and the lifting rib 12 to ensure that the metal sheet can accurately sense the change of the electrostatic field between the inner tube 1.

[0045] As a possible implementation, the dryness sensor is a 3D perspective drying sensor, which can emit countless electric field lines to the wall of the inner drum 1, forming a bipolar 3D detection field, dynamically scanning the clothes, and the changes in the moisture content of the clothes will affect the changes in the electrostatic field distribution. The sensor can sense these changes, and thus determine the moisture content of the clothes, that is, the degree of drying, through an intelligent algorithm. In addition, the dryness sensor can be a capacitive sensor or a resistive sensor, and can also be a humidity sensor. As long as it can detect the humidity in the inner drum 1, it is within the protection scope of the present invention.

[0046] Specifically, the connecting wire between the receiving coil 3 and the dry chip passes through the wall of the inner tube 1 and enters the interior of the lifting rib 12. A cable protection structure is provided outside the connecting wire. The cable protection structure is used to provide protection for the connecting wire, thereby achieving the purpose of waterproofing and preventing damage. Possibly, the cable protection structure can be a cable sheath, which is sleeved outside the connecting wire. The cable protection structure can also be a cable protection shell, which is installed on the inner tube 1, and the connecting wire is passed through the cable protection shell.

[0047] Continue reading Figure 1 The power supply component also includes a power storage module, which is arranged inside the lifting rib 12. The power storage module is electrically connected to the receiving coil 3, the dryness determination sensor, and the signal transmitting module respectively. The power storage module is used to store the electric energy generated by the induction of the receiving coil 3, and provide electric energy for the dryness determination sensor, signal transmitting module and other electrical devices in the inner tube 1 as a backup power supply. When the receiving coil 3 and / or the transmitting coil 2 fails or other situations occur where electric energy cannot be generated normally, the power storage module can also continue to provide a certain amount of electric energy for the dryness determination sensor, signal transmitting module and other electrical devices in the inner tube 1.

[0048] It will be understood by those skilled in the art that although the above Figure 1 It is described that the dry chip and the power storage module are both arranged inside the lifting rib 12, but this is not restrictive. Those skilled in the art can also provide protective shells for the dry chip and the power storage module as needed, as long as they can play a protective role. Figure 1 It is described that the sensing element 6 is arranged on the outside of the lifting rib 12, which is not restrictive. Those skilled in the art can also install the sensing element 6 directly on the inner wall of the inner tube 1 as needed, and an insulating plate is arranged between the sensing element 6 and the inner wall of the inner tube 1.

[0049] Continue reading Figure 1 The clothing processing device also includes a signal receiving module 8, which is communicatively connected to the signal transmitting module; the signal receiving module 8 is used to receive the detection information sent by the signal transmitting module and transmit it to the controller. The controller controls the clothing processing device to make a corresponding response and / or send a reminder message to the user according to the detection result of the dryness judgment sensor.

[0050] Possibly, the signal transmitting module is arranged inside the lifting rib 12, and the signal receiving module 8 is arranged at the upper front end of the shell of the clothing processing device, close to the controller, so as to facilitate the electrical connection and communication connection between the signal receiving module 8 and the controller; in addition, the signal receiving module 8 can also be arranged on the inner side of the rear shell 5 of the clothing processing device, and accordingly, the signal transmitting module is arranged on the outer side of the rear wall of the inner drum 1, which can effectively utilize the space between the outer side of the rear wall of the inner drum 1 and the inner side of the rear shell 5. The short distance between the signal transmitting module and the signal receiving module 8 also facilitates the rapid transmission of information.

[0051] It should be noted that the present invention does not limit the specific form of the signal transmission module. For example, it can be any form of Bluetooth, Mesh, ZigBee, Thread, Z-Wave, NFC, Hilink, UWB, and LiFi, as long as the signal can be sent. Furthermore, the clothing processing device may not be provided with a signal receiving module 8. The signal transmission module sends the detection result to the cloud server, and the cloud server sends the detection result to the clothing processing device. These adjustments do not deviate from the principle of the present invention and are within the protection scope of the present invention.

[0052] Possibly, the clothing processing device further includes a circuit board 7, which is disposed inside the lifting rib 12, and the dryness determination chip and the power storage module are integrated on the circuit board 7, which facilitates the electrical connection and communication connection between the dryness determination chip and the power storage module, optimizes the layout, and saves space. In addition, when the signal transmission module is disposed inside the lifting rib 12, it can also be integrated on the circuit board 7.

[0053] Optionally, the clothing processing device also includes a dynamic sealing structure, and the transmitting coil 2 and the receiving coil 3 are arranged within the coverage range of the dynamic sealing structure to prevent water in the inner drum 1 from entering the above-mentioned parts and affecting the normal use of the above-mentioned parts; optionally, the dynamic sealing structure includes a first dynamic sealing ring 9 and a second dynamic sealing ring 10, the first dynamic sealing ring 9 is an annular member connected to the outer side of the rear wall of the inner drum 1, and the first dynamic sealing ring 9 is slidably connected to the rear shell 5 of the clothing processing device, and the second dynamic sealing ring 10 is an annular member connected to the outer side of the front wall of the inner drum 1, and the second dynamic sealing ring 10 is slidably connected to the front shell of the clothing processing device.

[0054] See below Figure 2 , Figure 2 The structure of the first embodiment of the transmitting coil and the receiving coil of the present invention is shown. Figure 2As shown, the transmitting coil 2 is a C-shaped ring 21, that is, the transmitting coil 2 is a ring with an opening, and the C-shaped ring 21 is formed by winding the wire of the transmitting coil 2 from the outside to the inside in sequence, and the transmitting coil 2 is coaxial with the rotating shaft 11 of the inner cylinder 1; the receiving coil 3 is eccentrically arranged with the transmitting coil 2, and part or all of the receiving coil 3 is arranged within the coverage range of the C-shaped ring 21; the transmitting coil 2 is a C-shaped ring 21 obtained by winding the wire back and forth, and after the wire is energized, the magnetic flux lines generated cover the entire annular area of ​​the C-shaped ring 21. Since part or all of the receiving coil 3 is arranged within the coverage range of the C-shaped ring 21, the receiving coil When the transmitting coil 2 rotates with the inner cylinder 1, even if the position and / or shape of the transmitting coil 2 and / or the receiving coil 3 are deviated, the transmitting coil 2 can maintain continuous induction, thereby avoiding the intermittent power-on situation and improving the induction effect of the receiving coil 3; in addition, since the transmitting coil 2 is coaxial with the rotating shaft 11 of the inner cylinder 1 and the magnetic flux lines cover the entire annular area of ​​the C-shaped ring 21, the electromagnetic interference of the rotating shaft 11 on the transmitting coil 2 is reduced, and the receiving coil 3 is eccentrically arranged with the transmitting coil 2, which also reduces the electromagnetic interference of the rotating shaft 11 on the receiving coil 3, further improving the induction efficiency and improving the power-on effect of the electrical device.

[0055] It should be noted that the opening of the C-shaped ring 21 is very small. Since the opening is surrounded by wires, the opening is also covered by magnetic flux lines, which will not affect the continuous induction of the receiving coil 3 when it rotates with the inner tube 1.

[0056] See below Figure 3 , Figure 3 FIG. 2 shows the structure of the second embodiment of the transmitting coil and the receiving coil of the present invention. Figure 3As shown, the transmitting coil 2 includes a first conductive wire and a second conductive wire, the first conductive wire is folded back and wound from the outside to the inside to form a first C-shaped structure 22 including an inner ring 25 and an outer ring 24, the second conductive wire is connected to the end of the inner ring 25 and the end is folded back and wound between the inner ring 25 and the outer ring 24 to form a second C-shaped structure 23, the transmitting coil 2 is coaxial with the rotating shaft 11 of the inner cylinder 1; the receiving coil 3 is eccentrically arranged with the transmitting coil 2, and part or all of the receiving coil 3 is arranged within the coverage range of the second C-shaped structure 23; the magnetic flux lines generated by the first C-shaped structure 22 are within the area of ​​the first C-shaped structure 22, the magnetic flux lines generated by the second C-shaped structure 23 are within the area of ​​the second C-shaped structure 23, and the first C-shaped structure 22 and the second C-shaped structure 23 are connected. The two C-shaped structures 23 have an overlapping area, so the magnetic flux density in the area of ​​the second C-shaped structure 23 is the largest, and part or all of the receiving coil 3 is arranged within the coverage range of the second C-shaped structure 23. Therefore, when the receiving coil 3 rotates with the inner cylinder 1, it is in the area with the largest magnetic flux density most of the time, so that the induction effect is better; in addition, since the transmitting coil 2 is coaxial with the rotating shaft 11 of the inner cylinder 1 and the magnetic flux is concentrated in the area of ​​the second C-shaped structure 23, the electromagnetic interference of the rotating shaft 11 on the transmitting coil 2 is reduced, and the receiving coil 3 is eccentrically arranged with the transmitting coil 2, which also reduces the electromagnetic interference of the rotating shaft 11 on the receiving coil 3, further improving the induction efficiency and improving the power-on effect of the electrical device.

[0057] It should be noted that the openings of the first C-shaped structure 22 and the second C-shaped structure 23 are very small. Since wires are arranged around the openings, the openings are also covered by magnetic flux lines, which will not affect the continuous induction of the receiving coil 3 when it rotates with the inner tube 1.

[0058] It will be appreciated by those skilled in the art that although the above Figure 3 It is described that the transmitting coil 2 includes a first wire and a second wire, and is wound to form a first C-shaped structure 22 and a second C-shaped structure 23, but this is not restrictive. The transmitting coil 2 may also include a third wire, a fourth wire and more wires. The third wire is connected to the end of the outer ring 24 and is wound around the outer ring 24 to form a third C-shaped structure. The fourth wire is wound outside the third wire to form a fourth C-shaped structure, and so on, to enhance the magnetic flux density in the area of ​​the second C-shaped structure 23.

[0059] Last read Figure 1 and Figure 4 , Figure 4 The cross-sectional structure of the shielding layer of the present invention is shown. Figure 1As shown, the transmitting coil 2 is installed on the inner side of the rear shell 5 of the clothes processing device, and the receiving coil 3 is installed on the outer side of the rear wall of the inner drum 1. The arrangement positions of the transmitting coil 2 and the receiving coil 3 can effectively utilize the space outside the rear wall of the inner drum 1 and inside the rear shell 5. In addition, the close position of the transmitting coil 2 and the receiving coil 3 is conducive to the efficient induction of the receiving coil 3. Figure 4 As shown, a shielding layer 4 is provided between the transmitting coil 2 and the rear shell 5, and a shielding layer 4 is provided between the receiving coil 3 and the rear wall. The provision of the shielding layer 4 avoids electromagnetic interference and improves the inductive efficiency and safety.

[0060] It will be appreciated by those skilled in the art that although the above Figure 1 and Figure 4 It is described that the transmitting coil 2 is installed on the inner side of the rear shell 5 of the clothing processing device, but this is not restrictive. On a clothing processing device provided with an outer drum, such as a washing machine, a washer-dryer, etc., the transmitting coil 2 can also be arranged on the inner side of the rear wall of the outer drum, as long as it does not rotate with the inner drum 1. These adjustments do not deviate from the principles of the present invention and are within the protection scope of the present invention.

[0061] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned embodiments so that the present invention can be applied to more specific application scenarios.

[0062] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
