Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and specifically provides a drum-type clothing processing equipment, a movement control method, and an anti-wall sticking control method. Background Art

[0002] Currently, drum washing machines have increasingly larger wash capacities, with 10 kg being the minimum. Their spin speeds are also increasing, with 1200 rpm no longer considered high, and 1400 rpm not uncommon. As these washing machine parameters increase, the weight of the motor, casing, frame, and counterweight all increase, making them heavier and more difficult to transport. This is especially true when transporting indoors, as the packaging has already been removed, making it more difficult to move, which can easily lead to scratches on the floor and even injuries.

[0003] For built-in washing machines, fitting them into cabinets is a particular challenge. Many users, embracing simplicity, demand the closest possible distance between the washing machine and the cabinet. To achieve this, they're willing to spend exorbitant amounts on low-vibration direct-drive washing machines or use electric mechanisms to lift and lower them. Furthermore, some users resort to various mechanical mechanisms or manual lifting, which also wastes resources and effort. Once installed, washing machines are moved infrequently, averaging less than once a year. Such complex and expensive structures are unnecessary, incurring significant costs for consumers and resulting in a poor value for money. Furthermore, these structures are primarily used on high-end washing machines and fail to address the vast majority of washing machines requiring mobility.

[0004] In addition, when spinning clothes, some small items of clothing, such as scarves, tend to stick to the wall of the inner drum, causing you to forget to take them out after washing. There is currently no good way to deal with the problem of small items of clothing sticking to the wall.

[0005] Accordingly, the art needs a new drum-type laundry processing device, a movement control method, and an anti-sticking control method to solve the problems of the existing drum washing machine being difficult to move and small pieces of laundry easily sticking to the wall.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] First refer to Figure 1 , the drum washing machine of this application is introduced.

[0029] like Figure 1 and Figure 2 As shown, in order to solve the problems of the existing drum washing machine being difficult to move and small pieces of clothing easily sticking to the wall, the drum-type clothing processing device of the present invention includes a casing 1, an outer drum 2, a limiting assembly 3 and a locking portion 4. The outer drum 2 is arranged inside the casing 1; the limiting assembly 3 is arranged in the outer drum 2, and the limiting assembly 3 includes a moving part (which will be described in detail below - including the first movable bolt 31 and the second movable bolt 32 mentioned below) and a driving part (which will be described in detail below - including the bar electromagnet 33 mentioned below), and the driving part can drive the moving part to move along the axial direction of the outer drum 2; the locking portion 4 is arranged on the casing 1, and when the driving part drives the moving part to approach the locking portion 4, the moving part engages with the locking portion 4, so that the casing 1 and the outer drum 2 are locked in the height direction, and when the driving part drives the moving part away from the locking portion 4, the moving part disengages from the locking portion 4, so that the casing 1 and the outer drum 2 are unlocked in the height direction. For the sake of convenience, the drum-type clothing processing device of the present invention will be described below using a drum washing machine as an example. The height direction described herein refers to the up-down direction based on the front of the drum washing machine, and the horizontal direction refers to the left-right direction based on the front of the drum washing machine.

[0030] The advantage of this arrangement is that the housing 1 and outer drum 2 are locked in the vertical direction, limiting the vertical movement of the outer drum 2. However, the outer drum 2 can still vibrate horizontally. With this arrangement, when the inner drum of the drum washing machine is running at high speed, the housing 1, driven by the outer drum 2, will vibrate vertically due to eccentric force. Specifically, the feet of the drum washing machine may intermittently lift off the ground. At this time, the user can apply a certain force to the washing machine in the direction in which the drum washing machine is desired to move, thereby easily pushing or pulling the drum washing machine in, and by controlling the direction of the drum washing machine, it can be moved into the designed space, for example, into a built-in balcony cabinet. After moving into place, the user can hold the drum washing machine with one hand and press a button with the other hand to end the program. For example, the program can be ended by pressing a combination button on the drum washing machine. Of course, if the drum washing machine is provided with a voice recognition module, the moving program can be ended by voice control. The specific execution steps for ending the moving program are as follows: the driving member drives the moving member away from the locking portion 4, the moving member disengages from the locking portion 4, thereby unlocking the housing 1 and the outer drum 2 in the height direction, thereby ensuring the normal operation of the subsequent washing program. Among them, if you want to increase the vibration intensity, you can put some clothes in the inner drum appropriately. In addition, when there is a phenomenon of clothes sticking to the wall on the inner drum of the drum washing machine, the up and down vibration force will vibrate the clothes to separate from the inner drum, thereby avoiding the phenomenon of clothes sticking to the wall.

[0031] As a preferred embodiment, the driving part is a strip electromagnet 33, which is fixedly arranged, and the power line of the strip electromagnet 33 is connected to the main control module of the drum washing machine; the movable part includes a first movable bolt 31, which is arranged at the first end of the strip electromagnet 33, and the end of the first movable bolt 31 close to the strip electromagnet 33 is a magnet; the limiting assembly 3 also includes a guide part (to be introduced below, including the tube body 34 mentioned below), which is installed on the outer drum 2, and the first movable bolt 31 is movably arranged on the guide part.

[0032] When the housing 1 and the outer cylinder 2 are to be locked in the height direction, the main control module controls the strip electromagnet 33 to be energized, and by controlling the direction of the current, a repulsive force is formed between the strip electromagnet 33 and the first movable bolt 31, so that the first movable bolt 31 is guided by the guide part and combines with the locking part 4 to achieve locking in the height direction; when the housing 1 and the outer cylinder 2 are to be unlocked in the height direction, the current direction of the strip electromagnet 33 is controlled to be switched, so that a suction force is formed between the strip electromagnet 33 and the first movable bolt 31, so that the first movable bolt 31 is sucked back to its original position to achieve unlocking in the height direction.

[0033] Furthermore, the movable member also includes a second movable bolt 32, which is arranged at the second end of the bar electromagnet 33. The end of the second movable bolt 32 near the bar electromagnet 33 is a magnet; the end of the first movable bolt 31 near the bar electromagnet 33 has a magnetic pole opposite to the end of the second movable bolt 32 near the bar electromagnet 33; the second movable bolt 32 is movably arranged on the guide portion; further, the guide portion is a tube body 34, for example, it can be made of a non-magnetic material such as a stainless steel tube or an alloy tube to avoid magnetic attraction resistance between the first movable bolt 31, the second movable bolt 32 and the tube body 34, and the first movable bolt 31, the second movable bolt 32 and the bar electromagnet 33 are arranged in the tube body 34. Among them, the first movable bolt 31 and the second movable bolt 32 can be magnetized to make one end on the side of the bar electromagnet 33 magnetic.

[0034] When it is desired to lock the housing 1 and the outer cylinder 2 in the height direction, the main control module controls the strip electromagnet 33 to be energized, and by controlling the direction of the current, a repulsive force is simultaneously formed between the strip electromagnet 33 and the first movable bolt 31 and the second movable bolt 32, so that the first movable bolt 31 and the second movable bolt 32 are combined with the locking portion 4 under the guidance of the tube body 34 to achieve locking in the height direction; when it is desired to unlock the housing 1 and the outer cylinder 2 in the height direction, the current direction of the strip electromagnet 33 is controlled to be switched, so that a suction force is simultaneously formed between the strip electromagnet 33 and the first movable bolt 31 and the second movable bolt 32, so that the first movable bolt 31 and the second movable bolt 32 are sucked back to their original positions, achieving unlocking in the height direction.

[0035] The provision of the first and second removable bolts 31, 32 further restricts the vertical movement of the outer tube 2, ensuring that the entire body can rock in the vertical direction. Furthermore, this improves the bearing capacity of the movable parts, preventing breakage of the movable parts due to excessive loads. Furthermore, the first and second removable bolts 31, 32, and the bar-shaped electromagnet 33 are collectively disposed within the tubular body 34, enhancing its overall structural strength and protecting the first and second removable bolts 31, 32, and the bar-shaped electromagnet 33 from damage.

[0036] Furthermore, a first flange 21 and a second flange 22 are provided on the outer wall of the outer tube 2, a first step hole 211 is provided on the first flange 21, and a second step hole 221 is provided on the second flange 22; both ends of the tube body 34 are provided on the first step hole 211 and the second step hole 221.

[0037] The advantages of the above-mentioned setting method are: the setting of the first flange 21 and the second flange 22 improves the installation stability of the tube body 34 due to the two-point fixation; the setting of the first step hole 211 and the second step hole 221 can play a role in installing and fixing the tube body 34. Furthermore, the tube body 34 and the large hole clearance of the first step hole 211 and the second step hole 221 can fix the tube body 34 on the large hole of the step hole and ensure that the tube body 34 does not slip out of the step hole, thereby improving the installation reliability.

[0038] Furthermore, the first removable bolt 31 includes a first body 311 and a first thin column 312, the first body 311 is located on one side of the bar electromagnet 33, and the first body 311 is a magnet, and the first thin column 312 extends out of the first step hole 211; the second removable bolt 32 includes a second body 321 and a second thin column 322, the second body 321 is located on one side of the bar electromagnet 33, and the second body 321 is a magnet, and the second thin column 322 extends out of the second step hole 221.

[0039] The advantages of the above arrangement are that the provision of the first thin column 312 forms a boss on the first removable bolt 31, with the first body 311 being the thicker portion and the first thin column 312 being the thinner portion. The small hole in the first stepped hole 211 allows the first thin column 312 to extend while preventing the first body 311 from extending. Firstly, when the first body 311 and the bar electromagnet 33 form a repulsive force, the extension length of the first removable bolt 31 is limited, preventing the first thin column 312 from colliding too violently with the locking portion 4 and causing damage to the first thin column 312 or the locking portion 4. Furthermore, the distance the first thin column 312 extends into the locking portion 4 is controlled, leaving space for horizontal movement. Secondly, the complete disengagement of the first removable bolt 31 is prevented. The provision principles of the second thin column 322 and the second body 321 are the same and will not be further described. Furthermore, the first body 311 and the second body 321 cooperate with the inner cavity gap of the tube body 34, and the first thin column 312 and the second thin column 322 cooperate with the small hole gap of the first step hole 211 and the small hole gap of the second step hole 221 respectively. This arrangement can ensure the relative stability between the tube body 34 and the removable bolt, and avoid strong shaking. In addition, it can facilitate the installation and disassembly of components during maintenance, as well as facilitate the storage of lubricating oil and compensation for various errors.

[0040] Furthermore, a first tapered guide portion is provided on the first thin column 312, and a second tapered guide portion is provided on the second thin column 322. The advantage of this arrangement is that it can form a guide to facilitate alignment with the locking portion 4 (such as a hollow cylinder).

[0041] Continue to return to reference Figure 1 , and combined with Figure 2As a possible implementation manner, an upwardly inclined opening 212 is provided on the side wall of the first flange 21 or the second flange 22 , and the opening 212 is communicated with the first step hole 211 .

[0042] The advantages of the above arrangement are as follows: Taking the opening 212 provided on the first flange 21 as an example, the provision of the opening 212 ensures that the first removable bolt 31 and the tube body 34 are inserted into the first stepped hole 211 through the opening 212, facilitating installation and removal of the stopper assembly 3. The upwardly inclined opening 212 is intended to prevent the stopper assembly 3 from falling out of the opening 212. Optionally, an anti-fallout device, such as a screw or fixing adhesive, can be installed at the opening.

[0043] As a possible embodiment, the tube 34 is disposed at the bottom of the outer wall of the outer drum 2, and the locking portion 4 is disposed at the bottom of the inner wall of the casing 1. This arrangement, firstly, because the present invention restricts the vertical movement of the outer drum 2, the first and second flanges 21, 22 are primarily subjected to pressure from the outer drum 2. Compared to arrangements located on the side of the outer wall of the outer drum 2, which primarily withstand shear forces from the outer drum 2, this arrangement can prevent damage to the first and second flanges 21, 22. Secondly, it can fully utilize the internal space of the drum washing machine.

[0044] Furthermore, the locking portion 4 includes a first hollow cylinder 41 and a second hollow cylinder 42; a first fixing frame 5 and a second fixing frame 6 are provided on the casing 1, the first fixing frame 5 is arranged on the front side wall of the bottom of the casing 1, and the second fixing frame 6 is arranged on the rear side wall of the bottom of the casing 1; the first hollow cylinder 41 is arranged on the first fixing frame 5, and the second hollow cylinder 42 is arranged on the second fixing frame 6.

[0045] The advantages of the above-mentioned arrangement are: the arrangement of the first hollow cylinder 41 and the second hollow cylinder 42 facilitates the formation of a clearance fit with the first thin column 312 and the second thin column 322, thereby limiting the up and down movement of the outer cylinder 2; the arrangement of the first fixing frame 5 and the second fixing frame 6 can play a fixing role, ensure the stability of the combination of the thin column and the hollow cylinder, and avoid loosening. In addition, it can also protect the casing 1 from damage; in addition, the first fixing frame 5 is arranged on the front side wall of the bottom of the casing 1, and the second fixing frame 6 is arranged on the rear side wall of the bottom of the casing 1. This arrangement runs through the entire axial direction of the outer cylinder 2, and can ensure the best vibration effect in the up and down directions.

[0046] The following describes possible installation methods for the above implementation:

[0047] First, the power supply line of the strip electromagnet 33 has two leads, and the tube body 34 is provided with a first vertical opening and a second vertical opening. The first vertical opening is a hole perpendicular to the tube body 34 for one lead, and the second vertical opening is a hole perpendicular to the tube body 34 for the other lead. First, one lead of the strip electromagnet 33 is inserted into the first vertical opening of the tube body 34, then the strip electromagnet 33 is installed in the middle of the tube body 34, and finally the other lead of the strip electromagnet 33 is inserted into the second vertical opening. After installation, the strip electromagnet 33 is fixed in the tube body 34 with thermal conductive glue. While playing a limiting and fixing role, it is also conducive to the dissipation of heat generated during operation. After being fixed, it also facilitates the strip electromagnet 33 to exert repulsive and attractive forces on the first movable bolt 31 and the second movable bolt 32. Secondly, the first movable bolt 31 and the second movable bolt 32 are installed in the tube body 34 on both sides of the strip electromagnet 33. Then: one end of the limiting assembly 3 is installed into the second step hole 221 , and then the other end of the limiting assembly 3 is installed into the first step hole 211 through the upwardly inclined opening 212 .

[0048] The following combination Figure 3 , the mobile control method of this application is introduced.

[0049] like Figure 3 As shown, the movement control method of the drum type laundry processing device of the present invention includes the following steps:

[0050] Step S101: receiving a mobile function activation instruction.

[0051] Specifically, a drum washing machine can have a separate mobile program. When a user wants to move the drum washing machine, they can activate the mobile program by pressing a combination of buttons on the drum washing machine. Alternatively, if the drum washing machine is equipped with a voice recognition module, the user can activate the mobile program by speaking a wake-up word. Of course, the methods for activating the mobile program are not limited to the above methods, and any other activation methods are also possible, such as activating it through a mobile phone app. When the user activates the mobile program, the drum washing machine receives the instruction to activate the mobile function.

[0052] Step S102: controlling the driving member to drive the moving member to approach the locking portion, so that the moving member is engaged with the locking portion.

[0053] Step S103: After the moving part is engaged with the locking portion, the dehydration program is controlled to be activated.

[0054] When the drum washing machine receives the instruction to activate the movement function, the driving member starts to drive the moving member close to the locking part so that the moving member is combined with the locking part, thereby achieving the locking of the casing and the outer drum in the height direction, thereby limiting the up and down movement of the outer drum. At this time, by activating the dehydration program, high-frequency vibration is generated, causing the drum washing machine to vibrate in the up and down directions as a whole, thereby achieving the purpose of intermittently leaving the base of the drum washing machine off the ground.

[0055] As a specific embodiment, the control method includes: controlling the bar electromagnet to be energized so that the two poles of the bar electromagnet form a repulsive force with the first movable bolt and the second movable bolt respectively, thereby ejecting the first movable bolt and the second movable bolt from the tube body and inserting them into the first cylindrical portion and the second cylindrical portion respectively, thereby restricting the up and down movement of the outer drum, thereby achieving intermittent lifting of the feet of the drum washing machine from the ground. There are various ways to determine whether the first movable bolt and the second movable bolt are respectively inserted into the first cylindrical portion and the second cylindrical portion. For example, the duration after the bar electromagnet is energized can be determined. When the duration reaches a preset time, it is considered that locking has been achieved. Of course, it can also be determined by any other method, for example, a signal switch is provided on the first cylindrical portion and the second cylindrical portion, and the signal switch is provided with a signal contact. When the first thin column and the second thin column contact the signal contact, it is considered that locking has been achieved.

[0056] Step S104: receiving a mobile function closing instruction.

[0057] When the drum washing machine is moved into position, the user wants to close the mobile program. At this time, the user can send a mobile function closing instruction by pressing a combination of buttons; or send a mobile function closing instruction by voice, etc.

[0058] Step S105: Control the dehydration process to stop.

[0059] Step S106: After the dehydration process stops, the driving member is controlled to drive the movable member away from the locking portion, so that the movable member is disengaged from the locking portion.

[0060] When the drum washing machine receives a movement function shut-off instruction, the dehydration program is controlled to stop, that is, the motor that rotates the inner drum of the drum washing machine stops rotating. After the dehydration program stops, that is, after the motor stops rotating, the driving member drives the moving member away from the locking portion to disengage the moving member from the locking portion, thereby unlocking the housing and the outer drum in the height direction, thereby ensuring the normal operation of other washing programs.

[0061] As a specific implementation, the control method includes: when the dehydration program stops, controlling the current direction of the bar electromagnet to switch.

[0062] The unlocking process is performed only after the motor stops rotating, which can prevent the removable bolt from being smoothly sucked back or the occurrence of damage caused by collision between components during the process of disengaging the removable bolt from the cylindrical portion. The above arrangement can ensure the smooth unlocking process. In addition, the current direction of the bar electromagnet is controlled to switch, which can form an attractive force between the bar electromagnet and the first and second removable bolts, thereby sucking the first and second removable bolts back and achieving unlocking in the height direction.

[0063] Furthermore, after the first removable bolt and the second removable bolt are sucked back into the tube body, the power supply of the bar electromagnet is cut off. Since the first removable bolt and the second removable bolt are magnetic, they will be firmly adsorbed together with the iron core of the bar electromagnet, ensuring the reliability of the drum washing machine running other programs.

[0064] The following combination Figure 4 , the anti-adherence control method of this application is introduced.

[0065] like Figure 4 As shown, the anti-wall-sticking control method for a drum-type laundry processing device of the present invention comprises the following steps:

[0066] Step S201: After the washing program is finished, the driving member is controlled to drive the moving member to approach the locking portion so that the moving member is engaged with the locking portion.

[0067] Step S202: After the moving part is engaged with the locking portion, the dehydration program is controlled to be activated.

[0068] After the washing program is completed, in order to prevent the clothes from sticking to the wall, the driving part starts to drive the movable part close to the locking part so that the movable part is combined with the locking part, thereby locking the casing and the outer drum in the height direction, thereby limiting the up and down movement of the outer drum. At this time, the dehydration program is activated to create high-frequency vibration, so that the drum washing machine vibrates in the up and down directions as a whole, thereby shaking off the clothes stuck to the inner drum.

[0069] As a specific implementation method, the control method includes: after the small item washing program is completed, controlling the bar electromagnet to be energized so that the two poles of the bar electromagnet form a repulsive force with the first removable bolt and the second removable bolt respectively, driving the first removable bolt and the second removable bolt to pop out of the tube body and insert into the first cylindrical part and the second cylindrical part respectively; when the first removable bolt and the second removable bolt are inserted into the first cylindrical part and the second cylindrical part respectively, the dehydration program is controlled to be activated.

[0070] The above-mentioned setting method limits the up and down movement of the outer drum, and realizes the vibration of the drum washing machine in the up and down direction as a whole. Furthermore, the above-mentioned washing program can be a small-piece washing program. When washing small pieces of clothing, after drying, the small pieces of clothing are easily attached to the inner drum, especially when they are attached to the upper side of the inner drum, they are not easy to be seen by the user. Therefore, the above-mentioned control method avoids missing drying. Of course, the washing program can also be other programs, such as children's clothing washing or underwear washing, etc. In addition, the washing program can also be all washing programs, that is, the anti-sticking control method of the present invention is run after each washing is completed. In addition, the method of judging whether the first removable bolt and the second removable bolt are respectively inserted into the first cylindrical part and the second cylindrical part is the same as the above description and will not be repeated.

[0071] Step S203: After the first preset time period, the dehydration process is controlled to stop.

[0072] Step S204: After the dehydration process stops, the driving member is controlled to drive the movable member away from the locking portion, so that the movable member is disengaged from the locking portion.

[0073] After the inner drum rotates for a certain period of time, the clothes stuck to the wall are shaken down from the inner drum. At this time, the dehydration program is controlled to stop, that is, the motor is controlled to stop rotating. After the dehydration program stops, that is, when the motor stops rotating, the driving member drives the movable member away from the locking portion to disengage the movable member from the locking portion, thereby unlocking the housing and the outer drum in the height direction, thereby ensuring the normal operation of other washing programs.

[0074] As a specific implementation, the control method includes: after a first preset time period, controlling the motor that rotates the inner drum of the clothing processing device to stop rotating; when the motor stops rotating, controlling the current direction of the bar electromagnet to switch.

[0075] By controlling the current direction of the bar electromagnet to switch, an attractive force is formed between the bar electromagnet and the first and second movable bolts, thereby sucking the first and second movable bolts back and achieving unlocking in the height direction. In addition, the advantages of unlocking after rotation stops have been discussed above and will not be repeated here.

[0076] Furthermore, after the first removable bolt and the second removable bolt are sucked back into the tube body, the power supply of the bar electromagnet is cut off. Since the first removable bolt and the second removable bolt are magnetic, they will be firmly adsorbed together with the bar electromagnet, ensuring the reliability of the drum washing machine running other programs.

[0077] In another embodiment of the present invention, the driving member can be a combination of a motor and a gear, specifically, the motor is fixed to the outer cylinder, the output shaft of the motor is fixedly disposed in the mounting hole of the gear, the moving member is a rack, and the rack is slidably connected to the sliding groove of the outer cylinder, when the motor rotates in the forward direction, it can drive the rack to engage with the locking portion to achieve the height locking of the housing and the outer cylinder, and when the motor rotates in the reverse direction, it can drive the rack to disengage from the locking portion to achieve the height unlocking of the housing and the outer cylinder, wherein the locking portion can be a flat tube adapted to fit the rack. Of course, the structural form of the limit assembly is not limited to the above, and a push rod motor or a screw nut can also be used. As long as it can achieve that when the driving member drives the moving member toward the locking portion, the moving member engages with the locking portion, thereby locking the housing and the outer cylinder in the height direction, and when the driving member drives the moving member away from the locking portion, the moving member disengages from the locking portion, thereby unlocking the housing and the outer cylinder in the height direction, these do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0078] In summary, the structure and usage method of the present invention are simple. By simply changing some structures and procedures, the product value can be greatly increased, making it convenient for users to move the washing machine, clean the bottom of the washing machine, and install the washing machine in an embedded manner. In addition, it can also solve the problem of small pieces of clothing sticking to the wall.

[0079] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0080] For example, in an alternative embodiment, the setting position of the limit assembly 3 is not unique. Under the condition of being able to limit the up and down movement of the outer cylinder 2, its setting position can be adjusted. For example, it can be set at the top of the outer wall of the outer cylinder 2, etc. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0081] For example, in another replaceable embodiment, the specific structural form of the guide portion is not fixed. Under the premise of being able to guide the first removable bolt 31 and the second removable bolt 32, those skilled in the art can adjust the above-mentioned 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, and the first removable bolt 31 and the second removable bolt 32 are fixedly connected to the sliding rail. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0082] For example, in another alternative embodiment, the setting position of the strip electromagnet 33 is not unique. Under the condition that suction or repulsion can be formed between the first movable bolt 31 and the second movable bolt 32, its setting position can be adjusted. For example, it can be fixed on the outer tube 2, etc. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0083] For example, in another alternative embodiment, although the above embodiment is 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.

[0084] For example, in another alternative embodiment, although the above embodiment is described in conjunction with the first stepped hole 211 and the second stepped hole 221, this is not intended to limit the scope of protection of this application. For example, the first stepped hole 211 and the second stepped hole 221 can each be a circular hole, etc. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0085] For example, in another alternative embodiment, although the first removable bolt 31 is described in conjunction with the first body 311 and the first thin column 312, and the second removable bolt 32 is described in conjunction with the second body 321 and the second thin column 322, this is not intended to limit the scope of protection of this application. For example, the first removable bolt 31 and the second removable bolt 32 can be smooth cylinders, etc., and these do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0086] For example, in another alternative embodiment, although the above embodiment is described as having an upwardly inclined opening 212 on the first flange 21, this is not intended to limit the scope of protection of this application. For example, the opening 212 may not be provided, and the limit assembly 3 may be fixed in a non-detachable manner through injection molding. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0087] For example, in another alternative embodiment, the specific structure of the locking portion 4 is not fixed. Those skilled in the art may adjust the above device as long as it can lock the first removable bolt 31 and the second removable bolt 32. For example, it may be a sliding groove that fits with the first thin column 312 and / or the second thin column 322 (to ensure that they do not fall out), etc. These arrangements do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0088] For example, in another alternative embodiment, although the above embodiment is described with reference to the first fixing bracket 5 and the second fixing bracket 6, this is not intended to limit the scope of protection of this application. For example, the present invention may omit the first fixing bracket 5 and the second fixing bracket 6. Such an arrangement does not deviate from the principles of the present invention and thus falls within the scope of protection of the present invention.

[0089] Finally, it should be noted that although the present invention is described using a drum washing machine as an example, the drum-type laundry processing device of the present invention can obviously also be applied to other drum washing devices. For example, the drum-type laundry processing device can also be applied to shoe washing machines, sock washing machines, etc.
