Description

Technical Field

[0001] This invention belongs to the field of garment processing technology, specifically providing a drum-type garment processing device and its control method. Background Technology

[0002] With the continuous development of garment processing technology, users are placing increasingly higher demands on the overall performance of garment processing equipment. Specifically, as users accumulate more high-end garments, gentle processing programs designed for these items are gaining popularity. These programs are primarily used for delicate small garments such as silk scarves, pajamas, and underwear, offering advantages such as low friction and minimal damage. Furthermore, because these garments are typically lightweight and lightly soiled, the load on the drive motor during rotation (primarily the weight of the inner drum itself) is very low. When the garment processing equipment executes a gentle processing program, the inner drum does not rotate a full circle but instead oscillates within a certain range to achieve the gentle processing effect.

[0003] Furthermore, existing garment processing equipment typically uses direct-drive motors to achieve a oscillating effect, thus providing a gentle processing solution. While this method of using direct-drive motors does achieve the oscillation effect, this back-and-forth oscillation requires frequent reversing and starting / stopping of the motor. The motor's efficiency is usually lowest during startup, with most of the energy consumed as heat, and not effectively utilized. Therefore, existing garment processing equipment not only suffers from high energy consumption and low efficiency when performing gentle processing programs, but prolonged use of these programs can also easily damage the direct-drive motor itself, even leading to overheating and shutdown.

[0004] Accordingly, there is a need in the field for a new drum-type garment processing device and its control method to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, specifically the inadequacy of existing garment processing equipment in achieving gentle handling, this invention provides a drum-type garment processing device. The drum-type garment processing device includes a swing drive assembly, an outer drum, and an inner drum disposed within the outer drum. The swing drive assembly includes a permanent magnet and an electromagnet. One of the permanent magnet and the electromagnet is disposed on the circumferential sidewall of the inner drum, and the other is disposed at the bottom of the circumferential sidewall of the outer drum. The permanent magnet and the electromagnet are configured such that controlling the energization of the electromagnet controls the interaction between the electromagnet and the permanent magnet, thereby controlling the swing of the inner drum.

[0009] In the preferred embodiment of the above-mentioned drum-type garment processing equipment, the mounting port of the receiving cavity is located at the bottom rear side of the outer drum.

[0010] In the preferred embodiment of the above-mentioned drum-type garment processing equipment, a first Hall component is further provided in the receiving cavity. The first Hall component includes a first Hall element and a first magnetic shield. The first Hall element is disposed in the first magnetic shield so that the first Hall element can only detect the magnetic field change of the permanent magnet.

[0011] In the preferred embodiment of the above-mentioned drum-type garment processing equipment, a second Hall component and a third Hall component are provided on the outer side of the circumferential sidewall of the outer drum. The second Hall component and the third Hall component are respectively disposed on both sides of the electromagnet. The second Hall component includes a second Hall element and a second magnetic shield. The second Hall element is disposed in the second magnetic shield so that the second Hall element can only detect the magnetic field change of the permanent magnet. The third Hall component includes a third Hall element and a third magnetic shield. The third Hall element is disposed in the third magnetic shield so that the third Hall element can only detect the magnetic field change of the permanent magnet.

[0012] In the preferred embodiment of the above-mentioned drum-type garment processing equipment, the second Hall component is set at a height of two-thirds of the maximum swing height of the permanent magnet; and / or the third Hall component is set at a height of two-thirds of the maximum swing height of the permanent magnet.

[0013] In the preferred embodiment of the above-mentioned drum-type garment processing equipment, the outer drum has a semi-circular cross-sectional shape, and the inner drum has a fan-shaped cross-sectional shape, so that the inner drum can swing within the outer drum.

[0014] The present invention also provides a control method for a drum-type garment processing device, the drum-type garment processing device including a swing drive assembly, an outer drum, and an inner drum disposed in the outer drum. The swing drive assembly includes a permanent magnet and an electromagnet. One of the permanent magnet and the electromagnet is disposed on the circumferential sidewall of the inner drum, and the other of the permanent magnet and the electromagnet is disposed at the bottom of the circumferential sidewall of the outer drum. The permanent magnet and the electromagnet are configured such that controlling the energization of the electromagnet can control the interaction between the electromagnet and the permanent magnet, thereby controlling the swing of the inner drum. The control method includes: when the drum-type garment processing device is performing gentle operation, energizing the electromagnet with a first preset current intensity and a first current direction, thereby driving the inner drum to swing from an initial position toward a first direction; when the amplitude of the inner drum swinging toward the first direction reaches a first preset amplitude... When the inner cylinder swings to the initial position, the electromagnet is energized with a second preset current intensity and a second current direction; when the inner cylinder swings to the initial position, the electromagnet is energized with the second preset current intensity and the first current direction, thus driving the inner cylinder to swing in the second direction; when the amplitude of the inner cylinder swinging in the second direction reaches a second preset amplitude, the electromagnet is energized again with the second preset current intensity and the second current direction; when the inner cylinder swings to the initial position again, the electromagnet is energized again with the second preset current intensity and the first current direction, thus driving the inner cylinder to swing in the first direction; wherein, the first preset current intensity is greater than the second preset current intensity; the first current direction is the direction in which the electromagnet and the permanent magnet generate a repulsive force, and the second current direction is the direction in which the electromagnet and the permanent magnet generate an attractive force; the first direction and the second direction are opposite.

[0015] Those skilled in the art will understand that, in the technical solution of this invention, the drum-type garment processing device includes a swing drive assembly, an outer drum, and an inner drum disposed within the outer drum. The swing drive assembly includes a permanent magnet and an electromagnet. One of the permanent magnet and the electromagnet is disposed on the circumferential sidewall of the inner drum, and the other is disposed at the bottom of the circumferential sidewall of the outer drum. The permanent magnet and the electromagnet are configured such that controlling the energization of the electromagnet controls the interaction between the electromagnet and the permanent magnet, thereby controlling the swing of the inner drum. Based on the above configuration, this invention not only effectively improves the operating environment of the drive motor and increases garment processing efficiency, but also effectively reduces noise and vibration, and has a low installation cost, making it easy to promote and use. Furthermore, this invention utilizes a Hall effect sensor to monitor the swing amplitude of the inner drum, effectively ensuring that the inner drum swings only within a preset range, thereby ensuring a gentle processing effect and effectively protecting the garments.

[0030] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although this preferred embodiment is described in conjunction with the case where the drum-type clothes handling device is a drum washing machine, the drum-type clothes handling device described in this invention can obviously also be other devices, such as a drum dryer. Such changes in the specific type of the drum-type clothes handling device do not depart from the basic principles of the invention and fall within the scope of protection of the invention.

[0031] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] First refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the overall structure of the clothing processing tube according to the first preferred embodiment of the present invention; Figure 2This is a front sectional view of the garment processing drum according to the first preferred embodiment of the present invention. Figure 1 and 2 As shown, the drum washing machine of the present invention includes an outer drum 11, an inner drum 12 disposed in the outer drum 11, and a swing drive assembly. The inner drum 12 is rotatably connected to the outer drum 11, and the outer drum 11 is fixed to the casing of the drum washing machine by a shock-absorbing damping device. The swing drive assembly includes a permanent magnet 131 and an electromagnet 132. The permanent magnet 131 is disposed on the circumferential side wall of the inner drum 12, and the electromagnet 132 is disposed at the bottom of the circumferential side wall of the outer drum 11. The permanent magnet 131 and the electromagnet 132 are configured such that by controlling the energization of the electromagnet 132, the interaction between the electromagnet 132 and the permanent magnet 131 can be controlled, thereby controlling the swing of the inner drum 12. It should be noted that the present invention does not impose any restrictions on the specific placement and relative position of the permanent magnet 131 and the electromagnet 132. Those skilled in the art can adjust them according to actual usage requirements. For example, the permanent magnet 131 can be placed at the bottom of the circumferential sidewall of the outer cylinder 11, and the electromagnet 132 can be placed on the circumferential sidewall of the inner cylinder 12. As long as the energization of the electromagnet 132 is controlled, the interaction between the electromagnet 132 and the permanent magnet 131 can be controlled, thereby controlling the swing of the inner cylinder 12.

[0034] Furthermore, such as Figure 2 As shown, three lifting ribs 121 are provided on the circumferential inner wall of the inner drum 12. These lifting ribs 121 assist in the rotation of the inner drum 12 to lift clothes. Of course, this invention does not impose any limitations on the specific structure or number of lifting ribs 121; those skilled in the art can set them according to the actual usage requirements of the drum washing machine. As a preferred arrangement, a permanent magnet 131 is disposed in one of the lifting ribs 121, so as to effectively utilize the original hollow structure of the lifting rib 121 for installation, thereby achieving the installation of the permanent magnet 131 without altering the original structure. The permanent magnet 131 has a long strip structure, and those skilled in the art can set its magnetic pole orientation according to actual usage requirements. In addition, the other two lifting ribs 121 are provided with long strip counterweights 1211. The counterweights 1211 are made of non-magnetic material to effectively prevent the counterweights 1211 from generating force between them and the electromagnets 132. The weight of the counterweights 1211 is equal to the weight of the permanent magnets 131 to effectively balance the weight distribution in the inner cylinder 12, thereby effectively ensuring the balance of the inner cylinder 12 during rotation.

[0035] See next Figure 3 The figure is a side sectional view of the garment processing tube according to the first preferred embodiment of the present invention. Figure 2 and 3As shown, a receiving cavity 111 and a heating chamber 112 are formed at the bottom of the circumferential sidewall of the outer cylinder 11. The internal spaces of both the receiving cavity 111 and the heating chamber 112 are rectangular to facilitate the placement of corresponding components. The receiving cavity 111 is located at the bottom of the outer cylinder 11, and the heating chamber 112 is located at the upper right of the receiving cavity 111. A heating element is installed in the heating chamber 112 to heat the washing water when needed. It should be noted that technicians can adjust the wall thickness of the outer cylinder 11 above the receiving cavity 111 according to actual usage requirements. This ensures that a sufficiently large force is generated between the permanent magnet 131 and the electromagnet 132, while also effectively maintaining the local strength of the outer cylinder 11. Of course, technicians can also customize the specific shape and structure of the receiving cavity 111 according to actual usage requirements, as long as the electromagnet 132 can be installed within the receiving cavity 111.

[0036] Furthermore, the electromagnet 132 is disposed in the receiving cavity 111. The electromagnet 132 includes an iron core 1321 and a conductive winding 1322 wound around the iron core 1321. The iron core 1321 is fixed to the outer drum 11 by a fixing bracket. Of course, the fixing method of the iron core 1321 is not unique, and technicians can set it according to actual usage requirements. During use, the main control module of the drum washing machine can control the direction of the magnetic poles of the electromagnet 132 by controlling the direction of the current in the conductive winding 1322. When the magnetic poles of the electromagnet 132 are the same as the magnetic poles of the permanent magnet 131, a repulsive force is generated; when the magnetic poles of the electromagnet 132 are opposite to the magnetic poles of the permanent magnet 131, an attractive force is generated. With the corresponding control logic, the inner drum 12 can be controlled to swing relative to the outer drum 11 to achieve a gentle wash. In addition, the installation port of the receiving cavity 111 is preferably located at the bottom rear side of the outer drum 11, i.e. Figure 3 The outer cylinder 11 is positioned at the bottom right side to better ensure its overall structural strength. Of course, this is not a limiting location; technicians can set its specific position according to actual usage needs. For example, it can be located directly below the receiving cavity 111, as long as installation is feasible.

[0037] See next Figure 4 This figure illustrates an application scenario of the swing drive component of the present invention. For example... Figure 3 and 4As shown, a first Hall effect assembly 14 is also provided in the receiving cavity 111. The first Hall effect assembly 14 is located at the middle position of the top of the electromagnet 132. Of course, technicians can also adjust the specific position of the first Hall effect assembly 14 according to actual usage needs. Specifically, the first Hall effect assembly 14 includes a first Hall element 141, a first magnetic shielding wire 142, and a first magnetic shielding cover 143. The first Hall element 141 is connected to the main control module of the drum washing machine through the first magnetic shielding wire 142 for signal transmission. Of course, the first Hall element 141 can also transmit signals to the main control module of the drum washing machine wirelessly; the connection method is not limiting.

[0038] Furthermore, the first magnetic shielding cover 143 has a bowl-shaped structure and is made entirely of magnetic shielding material. The first Hall element 141 is disposed in this bowl-shaped structure to prevent interference from the magnetic field signal of the electromagnet 132, thereby effectively ensuring that the first Hall element 141 does not receive the magnetic field signal of the electromagnet 132. This ensures that the first Hall element 141 can only receive the magnetic field signal from the permanent magnet 131, so as to effectively monitor the oscillation of the inner drum 12. Based on the above settings, when the first Hall element 141 detects a signal, it indicates that the permanent magnet 131 has moved directly above the first Hall element 141. The voltage signal generated by the first Hall element 141 can be transmitted to the main control module of the drum washing machine, so that the main control module can control the current commutation in the conductive winding 1322 and thus switch the magnetic field direction of the electromagnet 132. Furthermore, it should be noted that the present invention does not impose any restrictions on the specific type of the first Hall element 141 or the specific material and structure of the first magnetic shield 143. Technicians can set these according to actual usage requirements, as long as the first Hall element 141 can monitor the magnetic field signal of the permanent magnet 131 and the first magnetic shield 143 can shield the magnetic field signal of the electromagnet 132.

[0039] Continue reading Figure 2 ,like Figure 2 As shown, a second Hall element 15 and a third Hall element 16 are also provided on the outer side of the circumferential sidewall of the outer cylinder 11. The second Hall element 15 is located at the upper left of the receiving cavity 111, and the third Hall element 16 is located at the upper right of the receiving cavity 111. The second Hall element 15 and the third Hall element 16 are at the same height, and both are located in the middle part of the outer cylinder 11 to effectively ensure the sensitivity of the monitoring. Of course, technicians can also adjust the specific positions of the second Hall element 15 and the third Hall element 16 according to actual usage requirements.

[0040] The second Hall effect assembly 15 includes a second Hall element 151, a second magnetic shielding wire 152, and a second magnetic shielding cover 153. A mounting hole is provided at the bottom left side of the outer drum 11, through which the second Hall element 151 is installed. The second Hall element 151 is connected to the main control module of the drum washing machine via the second magnetic shielding wire 152 for signal transmission. Alternatively, the second Hall element 151 can also transmit signals to the main control module of the drum washing machine wirelessly; the connection method is not limited as long as signal transmission is possible. The second magnetic shielding cover 153 has a cylindrical structure and is made entirely of magnetic shielding material. The second Hall element 151 is encased in this cylindrical structure to prevent interference from irrelevant magnetic field signals, thereby effectively ensuring that the second Hall element 151 can only receive magnetic field signals from the permanent magnet 131, thus effectively monitoring the oscillation of the inner drum 12.

[0041] Based on the above configuration, when the second Hall element 151 detects a signal, it indicates that the permanent magnet 131 has moved directly above the second Hall element 151. The voltage signal generated by the second Hall element 151 can be transmitted to the main control module of the drum washing machine, so that the main control module can control the current commutation in the conductive winding 1322 and thus switch the magnetic field direction of the electromagnet 132. Furthermore, it should be noted that this invention does not impose any restrictions on the specific type of the second Hall element 151 or the specific material and structure of the second magnetic shield 153. Those skilled in the art can set these parameters according to actual usage requirements, as long as the second Hall element 151 can detect the magnetic field signal of the permanent magnet 131 and the second magnetic shield 153 can shield the magnetic field signal of the electromagnet 132.

[0042] The third Hall effect assembly 16 includes a third Hall element 161, a third magnetic shielding wire 162, and a third magnetic shielding cover 163. A mounting hole is provided at the bottom right side of the outer drum 11, through which the third Hall element 161 is installed. The third Hall element 161 is connected to the main control module of the drum washing machine via the third magnetic shielding wire 162 for signal transmission. Alternatively, the third Hall element 161 can also transmit signals to the main control module of the drum washing machine wirelessly; the connection method is not limited as long as signal transmission is possible. The third magnetic shielding cover 163 has a cylindrical structure and is made entirely of magnetic shielding material. The third Hall element 161 is encased in this cylindrical structure to prevent interference from irrelevant magnetic field signals, thereby effectively ensuring that the third Hall element 161 can only receive magnetic field signals from the permanent magnet 131, thus effectively monitoring the oscillation of the inner drum 12.

[0043] Based on the above configuration, when the third Hall element 161 detects a signal, it indicates that the permanent magnet 131 has moved directly above the third Hall element 161. The voltage signal generated by the third Hall element 161 can be transmitted to the main control module of the drum washing machine, so that the main control module can control the current commutation in the conductive winding 1322 and thus switch the magnetic field direction of the electromagnet 132. Furthermore, it should be noted that this invention does not impose any restrictions on the specific type of the third Hall element 161 or the specific material and structure of the third magnetic shield 163. Those skilled in the art can set these parameters according to actual usage requirements, as long as the third Hall element 161 can monitor the magnetic field signal of the permanent magnet 131 and the third magnetic shield 163 can shield the magnetic field signal of the electromagnet 132.

[0044] As a preferred configuration, the second Hall element 15 and the third Hall element 16 are both positioned at two-thirds of the maximum swing height of the permanent magnet 131. The second Hall element 15 monitors the leftward swing amplitude of the permanent magnet 131, and the third Hall element 16 monitors the rightward swing amplitude of the permanent magnet 131. Of course, technicians can set the maximum swing height of the permanent magnet 131 according to actual usage requirements and adjust the current in the conductive winding 1322 accordingly. Repeated simulation tests revealed that when the permanent magnet 131 swings to two-thirds of its maximum swing height, the repulsive force of the electromagnet 132 on the permanent magnet 131 is very weak. Even if the magnetic poles of the electromagnet 132 reverse and generate an attractive force on the permanent magnet 131, the inner cylinder 12 can continue to swing to the maximum swing height under inertia.

[0045] Furthermore, it should be noted that although this preferred embodiment uses three sets of Hall effect components to monitor the magnetic field signal of the permanent magnet 131 and thus monitor the swaying of the inner cylinder 12, this monitoring method is only a preferred method and not a limiting one. Technicians can also adjust the monitoring method according to actual usage needs; for example, monitoring can also be achieved by setting a displacement detection device.

[0046] See next Figure 5 and 6 ,in, Figure 5 This is a schematic diagram of the overall structure of the clothing processing tube according to the second preferred embodiment of the present invention; Figure 6 This is a cross-sectional view of the clothing processing tube according to the second preferred embodiment of the present invention. Figure 5 and 6As shown, this invention also provides a novel small drum washing machine. This drum washing machine partially improves the structure of the outer drum 11 and inner drum 12. The outer drum 11 is set in a semi-cylindrical shape with a semi-circular cross-section, and the inner drum 12 is set in a quarter-cylindrical shape with a right-angled sector cross-section. This allows the swing drive assembly to directly drive the inner drum 12 to swing within the outer drum 11, thereby achieving washing. Based on this configuration, the aforementioned small drum washing machine no longer needs a drive motor; it only requires the swing drive assembly for operation, effectively meeting the gentle washing needs of high-end garments. This configuration not only effectively reduces costs but also effectively reduces noise and vibration. Furthermore, the overall height of the drum washing machine can be significantly reduced. Since high-end garments do not require spin-drying, the counterweight can be eliminated, resulting in a significant reduction in the overall size and weight of the drum washing machine, making it more convenient for users. Of course, it should also be noted that technicians can adjust the specific structure and shape of the outer drum 11 and inner drum 12 according to actual usage needs, as long as the drum washing machine can be driven by the swing drive assembly.

[0047] See next Figure 7 This figure is a flowchart illustrating the specific steps of the control method of the present invention. Figure 7 As shown, based on the structure of the drum washing machine described in the first preferred embodiment of the present invention, the control method of the present invention specifically includes the following steps:

[0048] S101: When the drum washing machine is performing a gentle wash, the electromagnet is energized with a first preset current intensity and a first current direction, thereby driving the inner drum to swing from the initial position toward the first direction.

[0049] S102: When the inner cylinder swings in the first direction to the first preset amplitude, the electromagnet is energized with a second preset current intensity and in the second current direction.

[0050] S103: When the inner cylinder swings to the initial position, the electromagnet is energized with a second preset current intensity and a first current direction, thereby driving the inner cylinder to swing in the second direction;

[0051] S104: When the inner cylinder swings in the second direction to the second preset amplitude, the electromagnet is energized again with the second preset current intensity and the second current direction.

[0052] S105: When the inner cylinder swings back to the initial position, the electromagnet is energized again with the second preset current intensity and the first current direction, thereby driving the inner cylinder to swing in the first direction.

[0053] S106: Determine whether the gentle wash is over; if yes, proceed to step S107; if no, proceed to step S102 again.

[0054] S107: De-energizes the electromagnet.

[0055] First, it should be noted that after the normal program (i.e., non-gentle wash program) of the drum washing machine ends, the inner drum 12 can still rotate slowly for a certain period of time. During its rotation, since one of the lifting ribs 121 is equipped with a permanent magnet 131, and when the electromagnet 132 is not energized, its iron core 1321 can always be attracted by the permanent magnet 131. That is, every time the inner drum 12 rotates, the permanent magnet 131 can attract the iron core 1321 once. Finally, under the action of this attraction, the lifting rib 121 equipped with the permanent magnet 131 can stop at the lowest position under the attraction of the iron core 1321. Therefore, every time the drum washing machine is started, the electromagnet 132 and the permanent magnet 131 are in the corresponding positions to effectively ensure the reliability of the gentle wash.

[0056] In step S101, when the drum washing machine is performing a gentle wash, the electromagnet 132 is energized with the first preset current intensity and the first current direction, thereby driving the inner drum 12 to swing from its initial position toward the first direction. The first current direction is the direction in which the electromagnet 132 and the permanent magnet 131 generate a repulsive force. Specifically, at the beginning of startup, the conductive winding 1322 is energized with the first preset current intensity and the first current direction. At this time, the first preset current intensity used is much greater than the second preset current intensity, and when the conductive winding 1322 is energized with the first current direction, the magnetic pole direction of the electromagnet 132 is the same as that of the permanent magnet 131. The permanent magnet 131 and the electromagnet 132 generate a large repulsive force, thereby creating conditions for unstable repulsive force, and thus driving the inner drum 12 to start to swing slightly. As the swing amplitude gradually increases, although the repulsive force generated by the magnetic field of the same polarity will decrease slightly, the repulsive arm increases rapidly, the total torque increases, and thus the swing speed can be effectively accelerated. It is understandable that the oscillation process is definitely bidirectional; that is, after the permanent magnet 131 oscillates to the left, it will definitely oscillate to the right. Therefore, the first direction is not definite; it is only used to indicate the initial oscillation direction of the permanent magnet 131. Of course, it should be noted that the present invention does not impose any restrictions on the specific value of the first preset current intensity, and those skilled in the art can set it according to actual usage requirements.

[0057] Furthermore, it should be noted that while two magnets can remain stable when attracted to each other, it is difficult for them to maintain a stable state when repelling each other. This is evident in devices like magnetic levitation gyroscopes and globes, where finding a stable levitation point is extremely difficult. It is simply impossible for a magnetic levitation gyroscope to remain stably levitated on a magnet without rotating. Similarly, in actual manufacturing processes, due to limitations in the machining precision and density of the inner cylinder 12, permanent magnet 131, electromagnet 132, and bearings, it is impossible for the inner cylinder 12 and outer cylinder 11 to be in a stable repulsive state when the electromagnet 132 is energized. This ensures the reliability of startup.

[0058] Next, in step S102, when the amplitude of the inner cylinder 12 swinging in the first direction reaches the first preset amplitude, the electromagnet 132 is energized with the second preset current intensity and the second current direction; wherein, the first preset current intensity is greater than the second preset current intensity, and the second current direction is the direction in which the electromagnet 132 and the permanent magnet 131 generate an attractive force, and the first direction and the second direction are opposite. It should be noted that those skilled in the art can set the specific values ​​of the second preset current intensity and the first preset amplitude according to actual usage requirements. In this preferred embodiment, the situation where the amplitude of the inner cylinder 12 swinging in the first direction reaches the first preset amplitude corresponds to: the permanent magnet 131 swinging to the left above the second Hall component 15, or the permanent magnet 131 swinging to the right above the third Hall component 16. At this time, the main control module of the drum washing machine can receive the voltage signal generated by the second Hall component 15 or the third Hall component 16. After receiving the signal, it energizes the electromagnet 132 with the second preset current intensity and the second current direction. That is, it reduces the current intensity in the conductive winding 1322 from the first preset current intensity to the second preset current intensity and switches its current direction. In this case, the magnetic pole direction of the electromagnet 132 is opposite to that of the permanent magnet 131, and the electromagnet 132 attracts the permanent magnet 131, thereby achieving a slight braking effect. Of course, although there is a slight braking effect, the permanent magnet 131 can still continue to swing to the maximum swing height under the action of inertia, so as to effectively ensure the washing effect.

[0059] It should be noted that, in this preferred embodiment, when the inner drum 12 swings upward to its maximum swing height and then swings downward back to the second Hall component 15 or the third Hall component 16 it just passed, although the Hall component outputs a voltage signal, the main control module of the drum washing machine can automatically process the voltage signal as an invalid signal and not trigger the current commutation in the conductive winding 1322. That is, the signals generated by the second Hall component 15 and the third Hall component 16 are effective at intervals. In other words, after the previous voltage signal has triggered the current commutation in the conductive winding 1322, the adjacent next voltage signal will be processed as an invalid signal in order to effectively ensure the normal operation of the swing.

[0060] Next, as the permanent magnet 131 swings to its maximum swing height and then falls back down, the attraction of the electromagnet 132 to the permanent magnet 131 increases. Under the combined effect of gravity and attraction, the rotation speed of the inner drum 12 further accelerates, quickly returning to its initial position, i.e., the position where the permanent magnet 131 is above the electromagnet 132. In step S103, when the inner drum 12 swings to the initial position, the electromagnet 132 is energized with the second preset current intensity and the first current direction, thus driving the inner drum 12 to swing in the second direction. That is, the first Hall component 14 can send a voltage signal to the main control module of the drum washing machine. The main control module energizes the electromagnet 132 with the second preset current intensity and the first current direction. The magnetic pole direction of the electromagnet 132 is again the same as the magnetic pole direction of the permanent magnet 131. The electromagnet 132 generates a repulsive force on the permanent magnet 131, so as to push the inner drum 12 to continue swinging.

[0061] Further, in step S104, when the amplitude of the inner cylinder 12 swinging in the second direction reaches the second preset amplitude, the electromagnet 132 is energized again with the second preset current intensity and the second current direction. It should be noted that technicians can set the specific value of the second preset amplitude according to actual usage requirements, and the first preset amplitude and the second preset amplitude are the same, that is, the first preset amplitude and the second preset amplitude correspond to the preset amplitudes on the left and right sides, respectively. In this preferred embodiment, the situation where the amplitude of the inner cylinder 12 swinging in the second direction reaches the second preset amplitude corresponds to: the permanent magnet 131 swinging to the left above the second Hall component 15, or the permanent magnet 131 swinging to the right above the third Hall component 16. At this time, the main control module of the drum washing machine can receive the voltage signal generated by the second Hall component 15 or the third Hall component 16. After receiving the signal, the electromagnet 132 is energized with the second preset current intensity and the second current direction. In this case, the magnetic pole direction of the electromagnet 132 and the magnetic pole direction of the permanent magnet 131 are opposite again, and the electromagnet 132 attracts the permanent magnet 131 again, thereby playing a slight braking effect again.

[0062] Furthermore, when the permanent magnet 131 swings to its maximum swing height and then falls back down, the attraction force of the electromagnet 132 on the permanent magnet 131 becomes increasingly stronger. Under the combined effect of gravity and attraction, the rotation speed of the inner drum 12 further accelerates, and it quickly returns to its initial position. In step S105, when the inner drum 12 swings back to the initial position, the electromagnet 132 is energized again with the second preset current intensity and the first current direction, thereby driving the inner drum 12 to swing again in the first direction, thus realizing the reciprocating swing of the inner drum 12. Next, in step S106, the main control module can determine whether the gentle wash program of the drum washing machine has ended; if it has not ended, the above cycle continues to drive the inner drum 12 to swing back and forth; if it has ended, step S107 is executed, that is, the main control module controls the electromagnet 132 to be de-energized.

[0063] Furthermore, after the gentle wash cycle ends, the electromagnet 132 loses its magnetism due to power failure. At this time, the inner drum 12 can still swing slowly for a certain period of time. During its swing, the iron core 1321 of the electromagnet 132 continuously attracts the permanent magnet 131. Under the action of this attraction, the lifting rib 121 with the permanent magnet 131 can stop at the lowest point, that is, the inner drum 12 returns to its initial position. Therefore, each time the drum washing machine is started, the electromagnet 132 and the permanent magnet 131 are in the corresponding positions to effectively ensure the reliability of the gentle wash.

Without departing from the principles 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 all fall within the scope of protection of the present invention.
