Description

Technical Field

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

[0002] Currently, drum washing machines have increasingly larger washing capacities, with 10 kg being the starting capacity, and spin speeds are getting higher and higher. 1200 rpm is no longer considered high, and 1400 rpm is not uncommon. With these improvements in specifications, the weight of the motor, casing, frame, and counterweights also increase, making the washing machine itself heavier. This makes it increasingly difficult to move, especially indoors, where the packaging has been removed, making it even more challenging and potentially causing scratches on the floor or even injuries to people.

[0003] For built-in washing machines, placing them inside cabinets presents a significant challenge. Many users who prioritize simplicity require the smallest possible distance between the washing machine and the cabinet, willing to pay exorbitant prices for low-vibration direct-drive machines or electric lifting mechanisms. Furthermore, some users utilize various mechanical structures to manually lift the washing machine, which also wastes resources and effort. Since washing machines are rarely moved after installation—less than once a year on average—such complex and expensive structures are completely unnecessary, forcing consumers to incur additional costs and resulting in extremely low cost-effectiveness. Moreover, these structures are mostly used in high-end washing machines and cannot accommodate the numerous washing machines that require relocation.

[0004] Accordingly, there is a need in the field for a new drum-type clothes handling device and a movement control method to solve the problem of difficulty in moving existing drum washing machines. Summary of the Invention

Detailed Implementation

[0040] 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 the guide portion is described as a tube in the specification, the present invention can obviously employ various other structures. For instance, the guide portion can be a sliding rail, adapted to a sliding groove formed on the outer cylinder to ensure it does not detach from the sliding rail, as long as the guide portion has a guiding effect.

[0041] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "height," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used 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," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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.

[0043] First refer to Figure 1 and Figure 2 The present invention will now be described in the form of a drum-type garment processing device.

[0044] To address the problem of difficulty in moving existing drum washing machines, the present invention provides a drum-type clothes handling device comprising a housing 1, an outer drum 2, a vibration generating device 3, and a movement driving device 4. The outer drum 2 is disposed inside the housing 1. The vibration generating device 3 can lock and unlock the housing 1 and the outer drum 2 in the height direction. The movement driving device 4 is located on the bottom side of the housing 1 and can drive the clothes handling device to move. For ease of description, the drum-type clothes handling device of the present invention will be described below using a drum washing machine as an example. Herein, the height direction refers to the vertical direction relative to the front of the drum washing machine, the horizontal direction refers to the horizontal direction relative to the front of the drum washing machine (left side is the left side of the drum washing machine in the horizontal direction, right side is the right side of the drum washing machine in the horizontal direction, front side is the direction of the front of the drum washing machine, and rear side is the direction of the back of the drum washing machine).

[0045] The advantages of the above-described configuration are as follows: the casing 1 and the outer drum 2 are locked in the height direction, restricting the vertical movement of the outer drum 2; however, it can still sway horizontally. With this configuration, under the condition that the inner drum of the drum washing machine is rotating at high speed, due to the eccentric force, the casing 1 will vibrate vertically under the drive of the outer drum 2. Specifically, the feet of the drum washing machine will intermittently lift off the ground. At this time, applying a certain force to the drum washing machine allows it to be easily pushed in or pulled out. This invention achieves automatic control of the drum washing machine's movement by controlling the movement drive device 4 to apply a certain force to the drum washing machine, thereby automatically moving it into the designed space, such as a built-in balcony cabinet.

[0046] As a preferred embodiment, the moving drive device 4 of the present invention is designed such that when the feet of the drum washing machine are off the ground, the moving drive device 4 can apply a driving force to the drum washing machine. In this case, a very small driving force can be applied to achieve easy movement, which can greatly save energy. At the same time, the moving direction of the drum washing machine can be controlled by the moving drive device 4 to achieve different movement needs.

[0047] The present invention will now describe the specific structure of the mobile drive device 4 according to the preferred embodiment described above.

[0048] In one possible implementation, the moving drive device 4 includes a second drive member 41, a roller 42, and an elastic member 43. The roller 42 is disposed on the bottom side of the casing 1. The roller 42 can be partially located in a mounting opening on the bottom shell of the casing 1, and the other part can be located on the outer side of the bottom shell, or it can be completely located on the outer side of the bottom shell. The second drive member 41 is drivenly connected to the roller 42 to drive the roller 42 to rotate. One end of the elastic member 43 is fixedly disposed, and the other end of the elastic member 43 is connected to the second drive member 41, so that the roller 42 can always maintain contact with the ground under the action of the elastic member 43. The second drive member 41 is also connected to the casing 1, so that when the roller 42 rotates, it can transmit force to the casing 1 through the second drive member 41 to push the drum washing machine to move. The elastic member 43 is preferably a spring, but other elastic devices, such as elastic rubber, can also be used. Furthermore, the roller 42 is preferably a flexible rubber wheel, which can improve its grip and thus ensure that the drum washing machine is given appropriate driving force.

[0049] When the vibration generating device 3 is activated and the washing machine is running at high speed, i.e. when the feet are intermittently off the ground, the second driving component 41 is controlled to operate. Since the washing machine can be easily moved by applying a small force when the feet are off the ground, the second driving component 41 of this invention can be a small driving component. The specific moving principle is as follows: under the action of the elastic component 43, no matter how the washing machine shakes, the roller 42 is always in contact with the ground. In addition, the second driving component 41 drives the roller 42 to rotate, so that the roller 42 interacts with the ground to generate friction. Since the roller 42 is connected to the second driving component 41 and the second driving component 41 is connected to the casing 1, the driving force converted from the friction is transmitted to the casing 1 through the second driving component 41, thereby realizing the movement of the washing machine. It should be noted that, since the drum washing machine is intermittently off the ground at high frequency, it is invisible to the naked eye. The bottom of the drum washing machine makes momentary contact with the ground and immediately leaves the ground after contact. Therefore, the roller 42 will not stop rotating for a long time, and thus will not cause damage to the second drive component 41, such as circuit burnout. On the other hand, the movement conditions of the drum washing machine are usually: cleaning the bottom of the drum washing machine or embedded installation, and it needs to be plugged in with the power cord. It will not be moved over long distances. Therefore, there is no risk of damage to the second drive component 41.

[0050] Furthermore, with the above-mentioned arrangement, since the roller 42 is always in flexible contact with the ground, no additional vibration will be generated when the drum washing machine is not moved, for example, when the drum washing machine is running; on the contrary, it will also have a proper vibration reduction and noise reduction effect. For example, when the drum washing machine is running the spin-drying program, the setting of the elastic element 43 can also reduce the phenomenon of shaking of the casing 1.

[0051] In one possible implementation, the second drive unit 41 includes a dual-output shaft motor, which comprises a motor body and output shafts. The output shafts extend to opposite sides of the motor body, and rollers 42 are respectively connected to the output shafts on both sides. Preferably, the output shafts of the dual-output shaft motor of the present invention can rotate in both directions, thereby enabling selective control of the drum washing machine to move forward or backward. Furthermore, as can be seen from the above analysis, the dual-output shaft motor of the present invention can be a small motor with relatively low driving force, thereby saving energy and reducing manufacturing and usage costs.

[0052] The advantages of the above setup are: firstly, the stability of the drum washing machine can be improved by setting up two rollers 42; secondly, the dual-output shaft motor can be provided with stable support by the rollers 42 connected on both sides, thereby ensuring the installation stability of the dual-output shaft motor.

[0053] In one possible implementation, the axial direction of the roller 42 is perpendicular to the axial direction of the outer cylinder 2.

[0054] The advantage of the above arrangement is that, since the axis of the roller 42 is perpendicular to the axis of the outer drum 2, the roller 42 can rotate towards the front or rear of the drum washing machine, thereby enabling the drum washing machine to move forward or backward. Since drum washing machines are typically designed as built-in units, their lateral movement is usually limited. Therefore, the above arrangement can smoothly move the drum washing machine out or into the machine, meeting a wider range of user needs.

[0055] In one possible implementation, the mobile drive device 4 also includes a connector 44, the first end of which is pivotally connected to the housing 1, and the second end of which is fixedly connected to the motor body.

[0056] The advantages of the above-described configuration are that it ensures both flexible contact between the rollers 42 and the ground, and also enables the movement of the drum washing machine. For example, when the drum washing machine moves on a relatively bumpy surface, the connecting piece 44 can pivot relative to the casing, which, compared to a fixed connection with the casing, avoids stress concentration at the connection point that could lead to breakage, and ensures flexible contact between the rollers 42 and the ground. On the other hand, when the feet are off the ground, the rollers 42 remain in contact with the ground, allowing the driving force to be transmitted through the motor body to the connecting piece 44, and then through the connecting piece 44 to the casing 1, thereby driving the drum washing machine to move.

[0057] Furthermore, the mobile drive device 4 also includes a first fixed frame 46 and a second fixed frame 47, which are respectively disposed on opposite sides of the housing 1; the first fixed frame 46 and the second fixed frame 47 are provided with second hollow cylinders 461; the mobile drive device 4 also includes a connecting shaft 48, the two ends of which are disposed inside the second hollow cylinders 461 on both sides and are clearance-fitted with the second hollow cylinders 461; the first end of the connecting member 44 is connected to the connecting shaft 48.

[0058] The connector 44 includes various design forms. Preferably, the connector 44 is plate-shaped, and the width of the plate is adapted to the length of the motor body, thereby increasing the contact area with the motor body, effectively transmitting force and improving the stability of the connection. Of course, the connector 44 can also be other shapes, such as columnar.

[0059] Furthermore, the first fixing bracket 46 and the second fixing bracket 47 are preferably L-shaped fixing brackets, which can improve the installation stability between them and the casing 1. The present invention does not limit the connection method between them and the casing 1. For example, screw connection, riveting or welding can be used. The two ends of the connecting shaft 48 are located inside the second hollow cylinder 461 and are clearance-fitted with the second hollow cylinder 461, which can realize the rotation of the connecting shaft 48 relative to the second hollow cylinder 461. Since the first end of the connecting member 44 is connected to the connecting shaft 48, the connecting member 44 is pivotally connected relative to the casing 1. In addition, this arrangement can also improve the stable control of the movement direction of the drum washing machine, that is, the force can be transmitted to the casing 1 on both sides through the connecting shaft 48, avoiding the deflection phenomenon when moving the drum washing machine.

[0060] In one possible implementation, the mobile drive device 4 also includes a fixing rod 45, with both ends of the fixing rod 45 connected to the housing 1. One end of the elastic member 43 is connected to the fixing rod 45, and the other end of the elastic member 43 is connected to the motor body. The elastic member 43 and the fixing rod 45 can be connected in various ways. For example, the fixing rod 45 is provided with a slot, and one end of the elastic member 43 is fixed in the slot. Alternatively, they can be connected by hooking or other means. The elastic member 43 and the motor body can also be connected in various ways. For example, they can be connected by an intermediate fixing member or directly welded to the motor body.

[0061] The advantages of the above-mentioned setting method are: it allows the elastic element 43 to be set perpendicular to the motor body, so that the elastic element 43 can play its best role, and the design length of the spring can be controlled by adjusting the design height of the fixing rod 45 according to the design needs.

[0062] Furthermore, the first fixing frame 46 and the second fixing frame 47 are provided with a first hollow cylinder 462, and the two ends of the fixing rod 45 are installed in the first hollow cylinder 462 on both sides.

[0063] The advantages of the above-mentioned arrangement are: since the two ends of the fixing rod 45 are installed inside the first hollow cylinder 462 on both sides, the inner wall of the first hollow cylinder 462 can be directly subjected to the pressure of the two ends of the fixing rod 45, and due to the large contact area, the installation stability of the fixing rod 45 can be improved.

[0064] Furthermore, the first fixing bracket 46 is located on the left side wall of the housing 1 (e.g., Figure 1 On the left side of the casing 1, the second fixing bracket 47 is located on the right side wall of the casing 1 (e.g., on the left side). Figure 1 On the right side of the drum washing machine. This arrangement facilitates the forward or backward movement of the drum washing machine. That is, when the roller 42 rolls forward or backward, the force is transmitted to the left and right walls of the casing 1, thus preventing the drum washing machine from becoming unstable and ensuring its movement stability. Furthermore, it is possible that the fixing rod 45 and the motor body are located at the bottom of the drum washing machine's center of gravity. That is, the motor body, under the action of the elastic element 43 and the connecting element 44, always remains at the bottom of the drum washing machine's center of gravity. Simultaneously, since the roller 42 is located on both sides of the motor body, it ensures that the overall balance of the drum washing machine is maintained even after the roller 42 generates friction with the ground. In this case, if... Figure 2 As shown, the first hollow drum 462 is located at the bottom corresponding to the center of mass of the drum washing machine. Preferably, the second hollow drum 461 is located on the front or rear side of the first hollow drum 462, for example, at the left side position shown in the figure.

[0065] The present invention will now describe the specific structure of the vibration generating device 3.

[0066] The vibration generating device 3 includes a limiting component 31 and a locking part 32. The limiting component 31 is disposed on the outer cylinder 2 and includes a moving part (which will be described in detail below) and a first driving part (which will be described in detail below). The first driving part can drive the moving part to move along the axial direction of the outer cylinder 2. The locking part 32 is disposed on the housing 1. When the first driving part drives the moving part to approach the locking part 32, the moving part engages with the locking part 32, thereby locking the housing 1 and the outer cylinder 2 in the height direction. When the first driving part drives the moving part away from the locking part 32, the moving part disengages from the locking part 32, thereby releasing the housing 1 and the outer cylinder 2 from the height direction.

[0067] Furthermore, the first driving component is a bar electromagnet 313, which is fixedly installed, and its power wire is connected to the main control module of the drum washing machine; the moving component includes a first movable bolt 311 and a second movable bolt 312, the first movable bolt 311 is located at the first end of the bar electromagnet 313, and the second movable bolt 312 is located at the second end of the bar electromagnet 313. The ends of the first movable bolt 311 and the second movable bolt 312 near the bar electromagnet 313 are magnets, and the magnetic poles of the end of the first movable bolt 311 near the bar electromagnet 313 and the end of the second movable bolt 312 near the bar electromagnet 313 are opposite; the limiting component 31 also includes a guide portion, which is installed on the outer drum 2, and the first movable bolt 311 and the second movable bolt 312 are movably installed on the guide portion. Preferably, the guide portion is a tube body 314, which can be made of non-magnetic materials such as stainless steel or alloy tubes to avoid magnetic attraction resistance between the first movable bolt 311, the second movable bolt 312 and the tube body 314. The first movable bolt 311, the second movable bolt 312 and the bar electromagnet 313 are disposed inside the tube body 314. The first movable bolt 311 and the second movable bolt 312 can be magnetized to make one end of the bar electromagnet 313 magnetic.

[0068] When locking the housing 1 and outer cylinder 2 in the height direction, the main control module controls the bar electromagnet 313 to be energized. By controlling the direction of the current, the bar electromagnet 313 simultaneously generates a repulsive force with the first movable bolt 311 and the second movable bolt 312. Thus, the first movable bolt 311 and the second movable bolt 312, guided by the tube body 314, engage with the locking part 32 to achieve locking in the height direction. When unlocking the housing 1 and outer cylinder 2 in the height direction, the current direction of the bar electromagnet 313 is switched, causing the bar electromagnet 313 to simultaneously generate an attractive force with the first movable bolt 311 and the second movable bolt 312. This attracts the first movable bolt 311 and the second movable bolt 312 back to their original positions, achieving unlocking in the height direction.

[0069] The first movable bolt 311 and the second movable bolt 312 restrict the vertical movement of the outer cylinder 2, ensuring the entire machine body can sway in the vertical direction. Furthermore, they increase the load-bearing capacity of the moving parts, preventing breakage due to excessive load. In addition, the first movable bolt 311, the second movable bolt 312, and the bar electromagnet 313 are all housed within the tube body 314, enhancing its overall structural strength and protecting these components from damage.

[0070] Furthermore, the outer wall of the outer cylinder 2 is provided with a first flange 21 and a second flange 22, the first flange 21 is provided with a first stepped hole, and the second flange 22 is provided with a second stepped hole; the two ends of the tube body 314 are provided on the first stepped hole and the second stepped hole.

[0071] The advantages of the above-mentioned arrangement are as follows: the arrangement of the first flange 21 and the second flange 22, due to the two-point fixation, improves the installation stability of the tube body 314; the arrangement of the first stepped hole and the second stepped hole can play a role in fixing the tube body 314; furthermore, the clearance fit between the tube body 314 and the large hole of the first stepped hole and the second stepped hole can fix the tube body 314 on the large hole of the stepped hole and ensure that the tube body 314 does not slip out of the stepped hole, thereby improving the installation reliability.

[0072] Furthermore, the first movable bolt 311 includes a first body and a first thin post. The first body is located on one side of the bar electromagnet 313 and is a magnet. The first thin post extends out of the first stepped hole. The second movable bolt 312 includes a second body and a second thin post. The second body is located on one side of the bar electromagnet 313 and is a magnet. The second thin post extends out of the second stepped hole.

[0073] The advantages of the above-described configuration are as follows: the first thin post allows the first movable pin 311 to form a protrusion, with the first body being its thicker portion and the first thin post its thinner portion. The small hole in the first stepped hole allows the first thin post to extend while preventing the first body from extending. Firstly, when the first body and the bar electromagnet 313 generate a repulsive force, the extension length of the first movable pin 311 is limited, preventing excessive impact between the first thin post and the locking part 32, which could damage either the first thin post or the locking part 32. Furthermore, it controls the insertion distance of the first thin post to the locking part 32, allowing for horizontal movement. Secondly, it prevents the first movable pin 311 from completely disengaging. The principle behind the second thin post and the second body is the same and will not be described further. Furthermore, the first and second bodies are fitted with the inner cavity of the tube 314 with clearance, and the first and second thin pillars are fitted with the small holes of the first and second stepped holes with clearance, respectively. This arrangement can ensure the relative stability between the tube 314 and the movable bolt, and prevent strong shaking. In addition, it facilitates the installation and disassembly of components during maintenance, and is convenient for storing lubricating oil and compensating for various errors.

[0074] Furthermore, the first thin column is provided with a first conical guide portion, and the second thin column is provided with a second conical guide portion. The advantage of this arrangement is that it can form a guide, facilitating alignment with the locking part 32 (such as a hollow cylinder).

[0075] As one possible implementation, the sidewall of the first flange 21 or the second flange 22 is provided with an upwardly inclined opening. When the first flange 21 is provided with an upwardly inclined opening, the opening is connected to the first stepped hole.

[0076] The advantages of the above-described configuration are as follows: Taking an opening on the first flange 21 as an example, the opening ensures that the first movable bolt 311 and the tube 314 are inserted into the first stepped hole through the opening, facilitating the installation and removal of the limiting component 31. The upward tilt of the opening prevents the limiting component 31 from coming out of the opening. Ideally, an anti-dislodgement device, such as a screw or adhesive, can be added to the opening.

[0077] In one possible implementation, the tube body 314 is disposed at the bottom of the outer side wall of the outer drum 2, and the locking part 32 is disposed at the bottom of the inner side wall of the casing 1. This arrangement has two advantages: first, since the present invention restricts the movement of the outer drum 2 in the height direction, the first flange 21 and the second flange 22 mainly bear the pressure from the outer drum 2. Compared to being disposed on the side of the outer side wall of the outer drum 2, where they mainly bear the shear force from the outer drum 2, this arrangement avoids damage to the first flange 21 and the second flange 22; second, it fully utilizes the internal space of the drum washing machine.

[0078] Furthermore, the locking part 32 includes a third hollow cylinder 321 and a fourth hollow cylinder 322; the housing 1 is provided with a third fixing frame 33 and a fourth fixing frame 34, the third fixing frame 33 is provided on the front side wall of the bottom of the housing 1, and the fourth fixing frame 34 is provided on the rear side wall of the bottom of the housing 1; the third hollow cylinder 321 is provided on the third fixing frame 33, and the fourth hollow cylinder 322 is provided on the fourth fixing frame 34.

[0079] The advantages of the above-mentioned arrangement are as follows: the third hollow cylinder 321 and the fourth hollow cylinder 322 are designed to facilitate a clearance fit with the first and second thin columns, thereby limiting the vertical movement of the outer cylinder 2; the third fixing bracket 33 and the fourth fixing bracket 34 provide a fixing function, ensuring the stability of the connection between the thin column and the hollow cylinder and preventing loosening. In addition, they also protect the casing 1 from damage; furthermore, the third fixing bracket 33 is located on the front side wall of the bottom of the casing 1, and the fourth fixing bracket 34 is located on the rear side wall of the bottom of the casing 1. This arrangement extends through the entire axial direction of the outer cylinder 2, ensuring the best vertical vibration effect.

[0080] The following describes the possible installation methods of the vibration generating device 3 in the above embodiments:

[0081] First, the power supply wire of the bar electromagnet 313 has two leads. The tube body 314 has a first vertical opening and a second vertical opening. The first vertical opening is a hole made perpendicular to the tube body 314 for one of the leads, and the second vertical opening is a hole made perpendicular to the tube body 314 for the other lead. First, one lead of the bar electromagnet 313 is inserted into the first vertical opening of the tube body 314. Then, the bar electromagnet 313 is installed in the middle of the tube body 314. Finally, the other lead of the bar electromagnet 313 is inserted into the second vertical opening. After installation, the bar electromagnet 313 is fixed in the tube body 314 with thermally conductive adhesive. This not only provides a limiting and fixing function but also facilitates the dissipation of heat generated during operation. After fixing, it also makes it easier for the bar electromagnet 313 to apply repulsive and attractive forces to the first movable bolt 311 and the second movable bolt 312. Next, the first movable bolt 311 and the second movable bolt 312 are installed into the two side tubes 314 of the bar electromagnet 313. Then: one end of the limiting component 31 is inserted into the second stepped hole, and then the other end of the limiting component 31 is inserted into the first stepped hole through the upwardly inclined opening.

[0082] The following describes the movement control method of the drum washing machine of the present invention.

[0083] like Figure 3 As shown, the motion control method of the present invention includes the following steps:

[0084] Step S100: Receive instructions from the portable washing machine.

[0085] Specifically, since the portable washing machine is used infrequently, having a dedicated button is unnecessary and prone to accidental operation. Therefore, the washing machine can be programmed with a separate moving program. Users can activate this program by pressing a combination of buttons on the washing machine when they want to move it. Alternatively, if the washing machine has a voice recognition module, users can activate the program using relevant wake-up phrases (e.g., "Move washing machine," "Move forward," etc.). Of course, the methods for activating the moving program are not limited to these; any other method is possible, such as activating it via a mobile app. When the user activates the moving program, the washing machine receives the command to move. It is understandable that the instruction to move the washing machine can be a simple instruction with an enable function (i.e., a movement direction instruction needs to be received again before the subsequent steps of controlling the washing machine to move), or it can be an instruction with both an enable function and a movement direction control function (i.e., a movement direction instruction does not need to be received again before the subsequent steps of controlling the washing machine to move, and the washing machine can be controlled to move directly based on the initially received instruction). Preferably, the movement procedure can be subdivided into forward, backward, and stop. In one possible embodiment, when the user presses the forward combination button, it is equivalent to receiving the instruction to move the washing machine, and in the subsequent steps of controlling the washing machine to move, the washing machine is controlled to move forward.

[0086] As one possible implementation, after receiving the instruction to move the washing machine, a reminder message is sent to add a small amount of dry clothes. This reminds the user to add a small amount of dry clothes, such as 1-2 pieces, and by manually increasing the eccentric vibration, the movement efficiency of the washing machine is improved.

[0087] Step S200: Control the vibration generator to lock the housing and outer cylinder in the height direction.

[0088] Step S300: After the vibration generator locks the casing and outer cylinder in the height direction, the dehydration program is activated.

[0089] Once the vibration generator locks the casing and outer drum in the height direction, it restricts the up-and-down movement of the outer drum. At this time, by activating the spin-drying program, high-frequency vibration is generated, causing the entire washing machine to vibrate in the up-and-down direction, thereby achieving the purpose of intermittently lifting the feet of the washing machine off the ground.

[0090] In one possible implementation, the bar electromagnet is energized so that its two poles repel the first and second movable pins, respectively. This ejects the first and second movable pins from the tube and inserts them into the third and fourth cylindrical sections, respectively, thereby restricting the vertical movement of the outer drum and intermittently lifting the washing machine's feet off the ground. There are various ways to determine whether the first and second movable pins are inserted into the third and fourth cylindrical sections. For example, the duration of energization of the bar electromagnet can be measured; when the duration reaches a preset time, locking is considered achieved. Alternatively, any other method can be used, such as installing signal switches with signal contacts on the third and fourth cylindrical sections. When the first and second pins contact the signal contacts, locking is considered achieved.

[0091] Step S400: Control the operation of the moving drive device to drive the washing machine to move.

[0092] As mentioned above, at this time, the movement drive device can be controlled to operate based on the instructions of the moving washing machine in step S100, so as to control the movement direction of the washing machine; or the movement direction instructions can be received again, for example, the instructions to move forward or backward (which can be in the form of voice instructions), so as to control the movement drive device to operate based on the movement direction instructions, thereby controlling the movement direction of the washing machine.

[0093] As one possible implementation, the output shaft of the second drive unit can be controlled to rotate in the forward or reverse direction to control the forward or backward movement of the washing machine.

[0094] Step S500: Receive the movement stop command.

[0095] Once the washing machine has been moved into position, if the user wants to stop the moving program, they can issue a stop command by pressing a combination of buttons or by issuing a stop command via voice.

[0096] Step S600: Control the mobile drive device to stop operating. For example, control the second drive component to de-energize.

[0097] Step S700: Control the spin-drying program to stop running. That is, control the motor that rotates the inner drum of the washing machine to stop rotating, for example, by turning off its power.

[0098] Step S800: After the dehydration process stops, control the vibration generator to unlock the casing from the outer cylinder in the height direction.

[0099] The casing and outer drum are unlocked in the height direction, ensuring the normal operation of other washing programs.

[0100] As one possible implementation, the current direction of the control bar electromagnet is switched after the spin-drying program stops. The locking is only initiated after the washing machine motor stops rotating, preventing the removable latch from failing to retract smoothly or causing damage due to impact during the disengagement of the latch from the drum. This arrangement ensures a smooth unlocking process. Furthermore, controlling the current direction of the control bar electromagnet creates an attractive force between it and the first and second removable latches, thereby retracting them and achieving unlocking in the height direction.

[0101] Furthermore, after the first and second movable plugs are drawn back into the tube, the power supply to the bar electromagnet is cut off. Since the first and second movable plugs are magnetic, they will be firmly attracted to the iron core of the bar electromagnet, ensuring the reliability of the washing machine in running other programs.

[0102] Since the second driving component can be a relatively small driving motor, in this case, the vibration generator must be activated first, followed by the movement drive. Otherwise, if the motor starts first, before the washing machine's vertical vibration has occurred (i.e., before the washing machine's feet have left the ground), the motor's driving force will be insufficient to move the washing machine, quickly burning out the motor. Similarly, after the washing machine is in position, the motor must be turned off before the vibration stops. After moving to the correct position, for a regular washing machine, you can hold it down with one hand and turn it off with the other. For a washing machine with a voice control module, you can use voice commands to end the movement program or turn it off after it's in position.

[0103] In summary, the drum-type washing machine of the present invention allows the washing machine to move easily using its own power plus a small amount of auxiliary power, which has the beneficial effect of turning the harm of vibration into mobility; in addition, its structure is simple and its use is simple, requiring only changes to some structures and programs to greatly increase the value of the product, and it is also convenient for cleaning the bottom of the washing machine and for embedded installation.

[0104] It should be noted that the above embodiments are merely 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 structure so that the present invention can be applied to more specific application scenarios.

[0105] For example, as an alternative embodiment of the present invention, the specific structure of the vibration generating device 3 can be adjusted. For instance, the vibration generating device 3 includes a motor, a locking rod, and a locking part 32. The motor is fixedly mounted on the bottom side of the outer cylinder 2, and a hollow cylinder is provided on the output shaft of the motor. The locking rod passes through the hollow cylinder, and the middle part of the locking rod is in clearance fit with the hollow cylinder. The housing 1 is provided with a locking part 32, such as a locking member with a C-shaped cross section. The locking member and the locking rod are in clearance fit. When the motor runs in the forward direction, it can drive the locking rod into the locking member to achieve locking of the housing 1 and the outer cylinder 2 in the height direction. When the motor runs in the reverse direction, it can drive the locking rod to disengage from the locking member to achieve unlocking of the housing 1 and the outer cylinder 2 in the height direction. These modifications do not deviate from the principle of the present invention. As long as the housing 1 and the outer cylinder 2 can be locked and unlocked in the height direction, they are all within the protection scope of the present invention.

[0106] For example, as an alternative embodiment of the present invention, the first driving member can be a combination of a motor and a gear. Specifically, the motor is fixed on the outer cylinder 2, the output shaft of the motor is fixedly disposed in the mounting hole of the gear, and the moving member is a rack. The rack is slidably connected in the sliding groove of the outer cylinder 2. When the motor rotates in the forward direction, it can drive the rack to engage with the locking part 32 to lock the housing 1 and the outer cylinder 2 in the height direction. When the motor rotates in the reverse direction, it can drive the rack to disengage from the locking part 32 to unlock the housing 1 and the outer cylinder 2 in the height direction. The locking part 32 can be a flat tube adapted to the rack. Of course, the structure of the limiting component 31 is not limited to the above-mentioned types. It can also be a push rod motor or a lead screw nut, as long as it can achieve the following: when the driving member drives the moving member to approach the locking part 32, the moving member engages with the locking part 32, thereby locking the housing 1 and the outer cylinder 2 in the height direction; when the driving member drives the moving member away from the locking part 32, the moving member disengages from the locking part 32, thereby releasing the housing 1 and the outer cylinder 2 from the height direction. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0107] For example, as an alternative embodiment of the present invention, the specific structure of the moving drive device 4 can be adjusted. For instance, drive components and rollers can be set at the four corners of the bottom side of the washing machine. As long as the movement of the washing machine can be achieved, it will fall within the protection scope of the present invention.

[0108] For example, as an alternative embodiment of the present invention, although the present invention is described in terms of connector 44, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted. For example, connector 44 can be omitted. In this case, the bottom side of the housing 1 is provided with a mounting port, and the motor body is installed in the mounting port, which can move up and down without detaching. This does not hinder the action of the elastic member 43 on the motor body. Thus, while ensuring that the roller 42 is always in contact with the ground, the driving force can be transmitted through the mounting port to realize the movement of the washing machine. These do not deviate from the principle of the present invention, and therefore all fall within the scope of protection of the present invention.

[0109] For example, as an alternative embodiment of the present invention, although the present invention is described with one end of the elastic member 43 fixedly set and the other end fixedly connected to the second driving member 41, its setting method can be adjusted. For example, the setting of the elastic member 43 can be omitted. In this case, the bottom side of the casing 1 is provided with a mounting port, and the motor body is set in the mounting port that can move up and down without disengaging. The roller 42 is always in contact with the ground by the gravity of the motor body itself. At the same time, the driving force can be transmitted through the mounting port to realize the movement of the washing machine. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0110] For example, as an alternative embodiment of the present invention, although the second drive unit 41 of the present invention is described as a dual-output shaft motor, this is not intended to limit the scope of protection of the present invention. Its configuration can be adjusted. For example, the second drive unit 41 may include a dual-output shaft motor and a reducer, the dual-output shaft motor and the reducer are connected, and then the reducer is connected to the roller 42, etc. These do not deviate from the principle of the present invention, and therefore all fall within the scope of protection of the present invention.

[0111] For example, as an alternative embodiment of the present invention, although the present invention is described with the axis of the roller 42 perpendicular to the axis of the outer drum 2, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted, such as with the axis of the roller 42 being parallel to the axis of the outer drum 2. As long as the movement of the washing machine can be achieved, it will fall within the scope of protection of the present invention.

[0112] For example, as an alternative embodiment of the present invention, although the present invention is described with one end of the elastic member 43 connected to the fixed rod 45, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted, such as being fixedly connected to the outer cylinder 2. As long as the elastic member 43 can be fixed, it will fall within the scope of protection of the present invention.

[0113] For example, as an alternative embodiment of the present invention, although the present invention is described with the mobile drive device 4 including the first fixed frame 46 and the second fixed frame 47, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted. For example, the first fixed frame 46 and the second fixed frame 47 can be omitted, or only one fixed frame can be provided. Correspondingly, the connecting shaft 48 can be provided with only one end in the second hollow cylinder 461 (e.g., the second hollow cylinder 461 is designed to be longer), and the fixing rod 45 can be installed with only one end in the first hollow cylinder 462 (e.g., the first hollow cylinder 462 is designed to be longer). These do not deviate from the principle of the present invention, and therefore all fall within the scope of protection of the present invention.

[0114] For example, as an alternative embodiment of the present invention, although the present invention is described with the first fixing frame 46 located on the left side wall of the housing 1 and the second fixing frame 47 located on the right side wall of the housing 1, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted. For example, the first fixing frame 46 can be located on the front side wall of the housing 1 and the second fixing frame 47 can be located on the rear side wall of the housing 1. As long as the movement of the washing machine can be realized, it will fall within the scope of protection of the present invention.

[0115] For example, as an alternative embodiment of the present invention, although the present invention is described with the fixing rod 45 and the motor body located at the bottom of the center of gravity of the washing machine, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted, for example, it can be not located at the bottom of the center of gravity of the washing machine. As long as the movement of the washing machine can be realized, it will fall within the scope of protection of the present invention.

[0116] For example, as an alternative embodiment of the present invention, although the movable component of the present invention is described in terms of the first movable bolt 311 and the second movable bolt 312, this is not intended to limit the scope of protection of the present invention. The arrangement can be adjusted. For example, the movable bolt can be provided on only one side. As long as the housing 1 and the outer cylinder 2 can be locked and unlocked in the height direction, it is within the scope of protection of the present invention.

[0117] For example, in an alternative embodiment, the setting position of the limiting component 31 is not unique. Under the condition that it can satisfy the requirement of limiting the vertical movement of the outer cylinder 2, its setting position can be adjusted. For example, it can be set on the top of the outer side wall of the outer cylinder 2. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0118] For example, in another alternative embodiment, the specific structural form of the guide portion is not fixed. Under the premise that it can guide the first movable bolt 311 and the second movable bolt 312, those skilled in the art can adjust the above device. For example, the guide portion can be a sliding rail, which is adapted to the sliding groove formed on the outer cylinder 2 to ensure that it does not fall off the sliding rail. The first movable bolt 311 and the second movable bolt 312 are fixedly connected to the sliding rail. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0119] For example, in another alternative embodiment, the position of the bar electromagnet 313 is not unique. As long as it can satisfy the requirement of forming an attractive or repulsive force with the first movable bolt 311 and the second movable bolt 312, its position can be adjusted. For example, it can be fixedly set on the outer cylinder 2. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0120] For example, in another alternative embodiment, although the above embodiments are described in conjunction with the first flange 21 and the second flange 22, this is not intended to limit the scope of protection of this application. For example, it can be replaced with a card holder, etc., which do not depart from the principle of the present invention and therefore will fall within the scope of protection of the present invention.

[0121] For example, in another alternative embodiment, although the above embodiments are described in conjunction with the first stepped hole and the second stepped hole, this is not intended to limit the scope of protection of this application. For example, the first stepped hole and the second stepped hole may each be a circular hole, etc., which do not depart from the principle of the present invention and therefore will fall within the scope of protection of the present invention.

[0122] For example, in another alternative embodiment, although the first movable pin 311 is described in conjunction with the first body and the first thin post in the above embodiment, and the second movable pin 312 is described in conjunction with the second body and the second thin post, this is not intended to limit the scope of protection of this application. For example, the first movable pin 311 and the second movable pin 312 can be smooth columns, etc., which do not depart from the principle of the present invention and therefore will fall within the scope of protection of the present invention.

[0123] For example, in another alternative embodiment, although the above embodiment is described with an upwardly inclined opening on the first flange 21, this is not intended to limit the scope of protection of this application. For example, the opening may not be provided, and the limiting component 31 may be fixed in a non-removable manner by injection molding. These do not deviate from the principle of the present invention and therefore fall within the scope of protection of the present invention.

[0124] For example, in another alternative embodiment, the specific structural form of the locking part 32 is not fixed. Under the premise that it can lock the first movable bolt 311 and the second movable bolt 312, those skilled in the art can adjust the above-mentioned device. For example, it can be a groove that is adapted to the first thin post and / or the second thin post (to ensure that it does not fall out). These adjustments do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0125] For example, in another alternative embodiment, although the above embodiments are described with a third fixing bracket 33 and a fourth fixing bracket 34, this is not intended to limit the scope of protection of this application. For example, the present invention may omit the provision of the third fixing bracket 33 and the fourth fixing bracket 34, without departing from the principle of the present invention, and therefore all such omissions would fall within the scope of protection of the present invention.

[0126] Although this invention is described using a drum washing machine as an example, the clothing processing device of this invention can obviously also be applied to other devices for clothing processing. For example, it can also be applied to shoe washing machines, etc.
