Description

Technical Field

[0001] This application relates to the field of laundry equipment technology, and in particular to a washing machine inner drum, a washing machine, and a control method. Background Technology

[0002] A washing machine is a common household appliance. A front-loading washing machine has an outer drum and an inner drum, with lifting ribs inside the inner drum. During operation, the inner drum rotates relative to the outer drum, and the lifting ribs rotate with the inner drum. As the lifting ribs rotate, they move the clothes inside the inner drum upwards, causing them to be tumbled and washed, thus achieving the purpose of cleaning the clothes.

[0003] Currently, the lifting ribs of drum washing machines are fixedly installed on the inner drum, resulting in a simple structure that cannot be adapted to different fabrics. Consequently, the cleanliness of clothes varies, failing to meet user needs. Summary of the Invention

[0004] To overcome the problems existing in the related technology, this application provides a washing machine inner drum with multiple lifting rib contact surfaces, which can select the corresponding lifting rib element contact surface according to the fabric of the clothes to wash clothes, improve the washing effect, and meet the washing needs of users for different clothes.

[0005] The first aspect of this application provides a washing machine inner drum, comprising:

[0006] A cylindrical body with an opening for contact surfaces on its cylindrical wall;

[0007] A lifting rib assembly has at least two lifting rib elements distributed circumferentially. Each lifting rib element has a lifting rib contact surface, and the lifting rib contact surface can be exposed to the inside of the cylinder through the opening of the contact surface.

[0008] A drive component is used to drive the lifting rib assembly to rotate about its own axis.

[0009] In one possible implementation of the first aspect above, the lifting rib assembly in the inner drum of the washing machine includes: a cylindrical frame, wherein the at least two lifting rib elements are disposed in the receiving space formed by the cylindrical frame;

[0010] The column frame has a first end face and a second end face on both sides.

[0011] In one possible implementation of the first aspect above, in the inner drum of the washing machine, the two ends of the lifting rib element are pivotally connected to the inner sides of the first end face and the second end face, respectively, so that the lifting rib element can rotate about the pivot axis, the pivot axis being the line connecting the pivot points of the two end faces of the column frame.

[0012] In one possible implementation of the first aspect above, the drive assembly in the inner drum of the washing machine includes a first drive shaft and a first track motor;

[0013] The first track motor is used to drive the first drive shaft to abut against or move away from the first end face of the column frame;

[0014] The first end face and the first drive shaft each have a first limiting structure that matches each other.

[0015] In one possible implementation of the first aspect above, the drive assembly in the inner drum of the washing machine further includes a second drive shaft and a second track motor;

[0016] The second track motor is used to drive the second drive shaft to abut against or move away from the first end face of the column frame;

[0017] The first end face has a shaft through hole through which the second drive shaft can pass;

[0018] The second drive shaft and the lifting rib element each have a matching second limiting structure. When the second track motor drives the second drive shaft to pass through the first end face, the second limiting structures of the second drive shaft and the lifting rib element are matched with each other.

[0019] In one possible implementation of the first aspect above, the inner drum of the washing machine is provided with a friction structure on the contact surface of the lifting rib; the friction structure includes at least one of a protrusion, a serrated groove, and a brush unit.

[0020] In one possible implementation of the first aspect above, in the inner drum of the washing machine, if the friction structure is a protrusion, the protrusion is arranged at intervals in the length direction and circumferential direction of the contact surface of the lifting rib.

[0021] If the friction structure is a sawtooth groove, the sawtooth groove is equidistantly distributed on the contact surface of the lifting rib;

[0022] If the friction structure is a brush unit, the brush units are equidistantly distributed on the contact surface of the lifting rib.

[0023] In one possible implementation of the first aspect above, the drive assembly in the inner drum of the washing machine further includes: a first stepper motor and a second stepper motor;

[0024] The first stepper motor is used to control the rotation amplitude of the first drive shaft;

[0025] The second stepper motor is used to control the rotation amplitude of the second drive shaft.

[0026] The second aspect of this application provides a washing machine, specifically including the inner drum of the washing machine described in the first aspect and any possible implementation thereof.

[0027] A third aspect of this application provides a control method for a washing machine, comprising:

[0028] Get the washing mode set by the user;

[0029] Determine the contact surface of the lifting ribs that is compatible with the washing mode;

[0030] The control drive component drives the lifting rib assembly to rotate, so that the contact surface of the matching lifting rib is exposed at the contact surface opening of the washing machine drum wall.

[0031] The technical solution provided in this application may include the following beneficial effects:

[0032] This application provides a washing machine inner drum, including a drum body, a lifting rib assembly, and a drive assembly. The lifting rib assembly has at least two lifting rib elements distributed circumferentially, each corresponding to a different lifting rib contact surface. When a user needs to wash clothes, different lifting rib contact surfaces are rotated according to the actual needs of the laundry, thereby improving the washing effect on different fabrics. Specifically, when the user selects a specific lifting rib contact surface or a washing mode corresponding to a specific lifting rib contact surface, the drive assembly drives the lifting rib assembly to rotate around its own axis, causing the specific lifting rib contact surface to be exposed at the contact surface opening on the washing machine drum wall (i.e., the lifting rib contact surface enters the washing area of ​​the washing machine inner drum).

[0051] Currently, the lifting ribs of drum washing machines are fixedly installed on the inner drum, resulting in a simple structure that cannot be adapted to different fabrics. Consequently, the cleanliness of clothes varies, failing to meet user needs.

[0052] To address the aforementioned issues, this application provides a washing machine inner drum. The lifting rib device has multiple clothing contact surfaces, allowing users to select the appropriate lifting rib element contact surface based on the fabric of the clothing for washing, thereby improving the washing effect and meeting the washing needs of users for different types of clothing.

[0053] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0054] Example 1

[0055] Please see Figures 1 to 4 The washing machine inner drum in this embodiment includes:

[0056] Cylinder 1 has a contact surface opening on its cylinder wall;

[0057] The lifting rib assembly 2 has at least two lifting rib elements 21 distributed circumferentially. Each lifting rib element 21 has a lifting rib contact surface 210, which can be exposed to the inside of the cylinder 1 through the contact surface opening.

[0058] The drive component 3 is used to drive the lifting rib component 2 to rotate around its own axis.

[0059] The lifting rib assembly 2 is disposed at the contact surface opening of the inner drum, and at least two lifting rib elements 21 are arranged circumferentially in the lifting rib assembly 2. Each lifting rib element 21 corresponds to a different lifting rib contact surface 210. When the drive assembly 3 drives the lifting rib assembly 2 to rotate, the lifting rib assembly 2 rotates around its own axis. The rotation of the lifting rib assembly 2 aligns a specific lifting rib contact surface 210 with the contact surface opening of the inner drum, exposing it at the contact surface opening on the washing machine drum wall. That is, the lifting rib contact surface 210 enters the washing area of ​​the washing machine drum.

[0060] Drive assembly 3 is located in the non-washing area outside the inner drum. When there is no washing task, the state of lift rib assembly 2 can be as follows: Figure 4 As shown, the lifting rib contact surface 210 of the currently exposed lifting rib element 21 inside the washing machine drum 1 is determined according to the previous washing task, and the state of the lifting rib assembly 2 at this time can also be as follows. Figure 1 As shown, the lifting rib contact surface 210 of the lifting rib element 21 is concealed within the lifting rib assembly 2. After the washing machine starts, when the user selects the washing mode, the washing machine determines whether the current lifting rib contact surface 210 is the currently set lifting rib contact surface 210 according to actual needs. If it does not belong to the currently set lifting rib contact surface 210, such as... Figure 2 and Figure 3 As shown, the program inside the washing machine can control the drive assembly 3 to first retract the currently exposed lifting rib contact surface into the lifting rib assembly 2, then control the lifting rib assembly 2 to rotate so that the corresponding lifting rib element 21 is aligned with the contact surface opening, and then control the already aligned contact surface opening of the lifting rib element 21 to rotate so that the corresponding lifting rib contact surface 210 is exposed in the contact surface opening of the washing machine, allowing the lifting rib contact surface 210 to enter the washing area of ​​the washing machine drum. After completing the corresponding operation control, the drive assembly 3 and the lifting rib assembly 2 separate, and then the washing task is performed.

[0061] It should be noted that the lifting rib element 21 can also be disposed on the outer peripheral surface of the lifting rib assembly 2, that is, at least two lifting rib elements 21 are provided on the outer peripheral surface of the lifting rib assembly 2. In this case, the lifting rib contact surface 210 of the lifting rib element 21 is exposed on the outer peripheral surface of the lifting rib assembly 2 and rotates with the rotation of the lifting rib assembly 2. By driving the component 3 to rotate the lifting rib assembly 2, a specific lifting rib contact surface 210 is directly exposed to the contact surface opening on the washing machine drum wall for washing clothes. Therefore, Figures 1 to 4 The lifting rib assembly 2 shown should not be construed as the only implementation of the embodiments of this application.

[0062] In this embodiment, please refer to Figure 5 and Figure 6 The lifting rib assembly 2 includes: a cylindrical frame 22, and at least two lifting rib elements 21 are disposed in the receiving space formed by the cylindrical frame 22; the cylindrical frame has a first end face 23 and a second end face (not shown) on both sides.

[0063] The columnar frame 22 is hollow, forming multiple internal storage spaces. Each storage space of the columnar frame 22 can accommodate a specific lifting rib element 21. The first end face 23 of the columnar frame 22 can be connected to the drive assembly 3. When the drive assembly 3 is connected to the first end face 23 of the columnar frame 22, it can drive the columnar frame 22 to rotate around its own axis, so that the lifting rib contact surface 210 of the specific lifting rib element 21 is exposed at the contact surface opening of the washing machine drum wall.

[0064] For example, the cylindrical frame 22 in this application embodiment can be cylindrical. When a cylindrical frame 22 is used, the cylindrical frame 22 has high stability during washing or rotation. During the washing process, the inner drum needs to rotate back and forth or rotate at high speed. Using a cylindrical frame can prevent the lifting rib assembly 2 from becoming loose due to the shift of the center of gravity when the inner drum rotates at high speed.

[0065] It should be noted that the columnar skeleton 22 can also be a polygonal columnar skeleton 22, such as a pentagonal prism, hexagonal prism, heptagonal prism, or any other prism with more than 3 sides. As long as the prism has the possibility of being hollowed out, it can be used as the columnar skeleton 22 in this embodiment. Figure 5 and Figure 6 The cylindrical skeleton 22 shown should not be construed as the only implementation of the embodiments of this application.

[0066] In another implementation, the columnar frame 22 can be detachably installed on the contact surface opening, so that when consumables need to be replaced, the inner drum and washing machine do not need to be disassembled, thus reducing maintenance costs.

[0067] In this embodiment, please refer to Figure 5 and Figure 6 The two ends of the lifting rib element 21 are pivotally connected to the inner sides of the first end face 23 and the second end face, respectively, so that the lifting rib element 21 can rotate around the pivot axis. The pivot axis is the line connecting the pivot points of the two end faces of the column frame (it should be noted that the pivot axis is a virtual axis, which only represents a reference line for the rotation of the lifting rib element).

[0068] In practical applications, the inner sides of the two end faces of the column-shaped fixing bracket can be positioned using positioning grooves. The lifting rib element 21 is installed on the positioning groove, and a through hole for connecting the drive assembly 3 is opened in the positioning groove provided on the first end face 23. The drive assembly 3 is rotatably connected to the lifting rib element 21 via a pivot shaft. After the washing operation starts, the specific lifting rib contact surface 210 is rotated to the opening of the inner drum contact surface, so that the lifting rib contact surface 210 enters the washing area of ​​the washing machine inner drum. During non-washing processes, both the lifting rib assembly 2 and the lifting rib element 21 are disconnected from the drive assembly 3.

[0069] In another implementation, the contact surface of the lifting rib element 21 disposed in the cylindrical frame 22 can be exposed on the outer peripheral surface of the cylindrical frame 22. That is, the lifting rib element 21 is fixed on the outer peripheral surface of the cylindrical frame 22, and the contact surface of the lifting rib is directly exposed on the side of the cylindrical frame 22. When the drive assembly 3 is controlled to rotate the cylindrical frame 22, the corresponding lifting rib contact surface can be directly exposed on the contact surface opening of the washing machine drum wall, without the need for additional control of the drive assembly 3 to rotate the lifting rib element 21.

[0070] In another implementation, the lifting rib element 21 is detachably pivotally connected to the columnar frame 22. When consumables need to be replaced, it is not necessary to disassemble the inner drum and washing machine, which can reduce maintenance costs. The corresponding lifting rib element 21 can also be replaced according to the fabric of the clothes.

[0071] When the user needs to wash clothes, according to the actual needs of washing clothes, the lifting rib assembly 2 is rotated, and the lifting rib element 21 is rotated so that the specific lifting rib contact surface 210 is exposed inside the inner drum of the washing machine for washing clothes; specifically, firstly, the lifting rib assembly 2 is driven to rotate by the drive assembly 3 so that the corresponding lifting rib element 21 is aligned with the opening of the inner drum contact surface, and then the lifting rib element 21 is rotated by controlling the drive assembly 3 to rotate the current lifting rib contact surface 210 to the opening of the inner drum contact surface, so that the lifting rib contact surface 210 enters the washing area of ​​the inner drum of the washing machine, thereby adapting to the washing requirements of different clothing fabrics.

[0072] Example 2

[0073] In practical applications, a single set of drive shafts and track motors can be used to connect the lifting rib assembly 2 and the lifting rib element 21, or two sets of drive shafts and track motors can be used to connect and rotate the lifting rib assembly 2 and the lifting rib element 21 respectively. This application embodiment designs a corresponding structure. Based on the above embodiment 1, please refer to... Figures 1 to 4 The drive assembly 3 in the inner drum of the washing machine in this embodiment of the application further includes: a first drive shaft 31 and a first track motor (not shown).

[0074] The first track motor is used to drive the first drive shaft 31 to abut against or move away from the first end face 23 of the column frame 22; the first end face 23 of the column frame 22 and the first drive shaft 31 respectively have mutually matching first limiting structures 26.

[0075] Specifically, the first limiting structure 26 may be provided on the end face of the first drive shaft 31 with a structure such as a cross protrusion, a triangular protrusion, a cross groove, a triangular groove, a four-corner protrusion, or a four-corner groove. Correspondingly, a structure that matches the first drive shaft 31 is provided at the center of the first end face 23 of the columnar fixing frame. When the first drive shaft 31 abuts against the first end face 23 of the columnar frame 22, the cross protrusion on the end face of the first drive shaft 31 and the cross groove on the first end face 23 of the columnar frame 22 are riveted together, thereby realizing the rotation of the lifting rib assembly 2 and exposing the corresponding lifting rib contact surface 210 inside the inner cylinder.

[0076] In this embodiment, the drive assembly 3 further includes a second drive shaft 32 and a second track motor (not shown); the second track motor is used to drive the second drive shaft 32 to abut against or move away from the first end face 23 of the column frame; the first end face 23 has a shaft through hole 213 that allows the second drive shaft 32 to pass through; the second drive shaft 32 and the lifting rib element 21 each have a matching second limiting structure, which is distributed and fits with the second limiting structure of the second drive shaft 32 and the lifting rib element 21 when the second track motor drives the second drive shaft 32 to pass through the first end face 23.

[0077] In practical applications, the lifting rib element 21 is set in the receiving space of the lifting rib assembly 2. The lifting rib contact surface 210 of the lifting rib element 21 can be hidden in the receiving space. When a specific lifting rib element 21 is needed, the corresponding lifting rib element 21 can be connected through the second drive shaft 32 and the second track motor. By selecting the lifting rib element 21, the specific contact surface can be exposed from the receiving space by rotation and exposed at the opening of the inner cylinder contact surface. More specifically, the second limiting structure can be provided on the end face of the second drive shaft 32, such as a cross protrusion, a triangular protrusion, a cross groove, a triangular groove, a four-corner protrusion, or a four-corner groove. Correspondingly, a structure that matches the first drive shaft 31 is provided on the end face of the lifting rib element 21, such as a cross groove, a triangular groove, a cross protrusion, a triangular protrusion, or a four-corner protrusion. At the same time, corresponding shaft through holes 213 are opened at the positions of the columnar skeleton 22 corresponding to the two end faces of the lifting rib element 21. When the first drive shaft 31 and the first track motor have rotated the corresponding lifting rib element 21 in the lifting rib assembly 2 to the opening of the contact surface of the corresponding inner cylinder, the second drive shaft 32 and the second track motor make the lifting rib element 21 abut against the second limiting structure of the second rotating shaft 32 to achieve rotation, and rotate the current lifting rib element 21 so that the lifting rib contact surface is exposed inside the inner cylinder.

[0078] In this embodiment, the drive component 3 further includes: a first stepper motor 35 and a first stepper motor 36;

[0079] The first stepper motor 35 is used to control the rotation amplitude of the first drive shaft 31;

[0080] The first stepper motor 36 is used to control the rotation amplitude of the second drive shaft 32.

[0081] For example, when the lifting rib assembly 2 has three lifting rib elements 21, the three lifting rib elements 21 are evenly distributed within the cylindrical frame 22, and the central axes of adjacent lifting rib elements 21 are 120° apart. The stepper motor has high precision and can perform positioning with high accuracy. Therefore, during the washing process, the stepper motor can complete the replacement of the corresponding lifting rib elements with a rotation range of 120°, avoiding situations where the lifting rib assembly 2 and the lifting rib elements 21 cannot open their contact surfaces, thus improving the user experience.

[0082] More specifically, the drive assembly 3 may also include two slide rails 37, on which a first stepper motor 35 and a first stepper motor 36 are respectively arranged. The first track motor is a third stepper motor (not shown), and the second track motor is a fourth stepper motor (not shown). The third stepper motor and the fourth stepper motor are respectively arranged on one side of the slide rail 37. The third stepper motor controls the first stepper motor 35 to move horizontally on the slide rail 37; the fourth stepper motor controls the first stepper motor 36 to move horizontally on the slide rail 37, thereby realizing the connection and rotation of the lifting rib assembly 2 and the lifting rib element 21.

[0083] In another embodiment, the first drive shaft 31 and the second drive shaft 32 may share the first track motor.

[0084] More specifically, the drive assembly 3 may further include two slide rails 37, on which a first stepper motor 35 and a first stepper motor 36 are respectively arranged. A first track motor, which is a third stepper motor, is arranged between the two slide rails 37. The third stepper motor is used to control the first and second stepper motors to move horizontally in opposite directions on the slide rails 37. When the first stepper motor 35 approaches the first end face 23 of the cylindrical frame 22, the first stepper motor 36 moves away from the first end face 23 of the cylindrical frame 22. At this time, the first stepper motor 35 abuts against the first end face 23 of the cylindrical frame 22 and rotates the lifting rib assembly 2. When the third stepper motor drives the first stepper motor 36 to approach the first end face 23 of the cylindrical frame 22, the first stepper motor 35 moves away from the first end face 23 of the cylindrical frame 22. At this time, the first stepper motor 36 abuts against the lifting rib element 21 and rotates the lifting rib element 21, so that the corresponding lifting rib contact surface 210 is exposed inside the inner cylinder.

[0085] Example 3

[0086] In order for the washing machine drum described in Examples 1 and 2 to achieve washing effects for different fabrics, this application also designs a corresponding friction structure. Based on Examples 1 and 2 above, please refer to... Figure 8 and Figure 9 In this embodiment of the application, the contact surface 210 of the lifting rib in the inner drum of the washing machine is provided with a friction structure; the friction structure includes at least one of the following: a protrusion 211, a serrated groove, and a brush unit.

[0087] Specifically, if the friction structure is a protrusion 211, the protrusion 211 is arranged at intervals in the length direction and the circumferential direction of the lifting rib contact surface 210;

[0088] If the friction structure is a sawtooth groove, the sawtooth groove is equidistantly distributed on the contact surface 210 of the lifting rib;

[0089] If the friction structure is a brush unit, the brush units are equidistantly distributed on the contact surface 210 of the lifting rib.

[0090] In practical applications, the friction structure of the lifting rib contact surface 210 can be protrusions 211 arranged at intervals in the length and circumferential directions of the lifting rib contact surface 210, serrated grooves and brush units distributed at equal intervals on the lifting rib contact surface 210. The three different friction structures can be set on a single lifting rib element 21 or can be arranged in combination on a single lifting rib element 21.

[0091] For example, the material of the friction structure of the lifting rib contact surface 210 can be selected from different materials of the lifting rib element 21, such as plastic, wood, metal, etc., depending on the material and hardness of the fabric. The material of the lifting rib element 21 can be cross-matched with the friction structure to achieve a stronger cleanliness.

[0092] It should be noted that, Figure 9 and Figure 10 The bump 211 shown is only for adaptation. Figure 9 The friction structure of the lifting rib contact surface 210 shown is one embodiment of the friction structure involved; however, in practical applications, the friction structure of the lifting rib contact surface 210 can also take other forms. It is not excluded that irregularly shaped protrusions 211, serrated grooves, brush units, or other structures with rough surfaces can also achieve the washing function of this embodiment; therefore, Figure 9 The friction structure shown should not be construed as the only implementation of the embodiments of this application.

[0093] During washing, the lifting rib contact surface 210 with a friction structure of protrusions 211, serrated grooves or brush units is selected according to different fabrics. The corresponding friction structure is exposed inside the inner drum by the drive component 3, so as to achieve different washing effects for different fabrics.

[0096] In this embodiment of the application, the inner drum of the washing machine includes a plurality of lifting rib assemblies 2; wherein the lifting rib assembly 2 includes a plurality of lifting rib elements 21, and the friction structure of the lifting rib contact surface 210 can bring a suitable level of cleanliness to different fabrics.

[0101] The control drive component 3 drives the lifting rib component 2 to rotate, so that the matching lifting rib contact surface 210 is exposed at the contact surface opening of the washing machine drum wall.

[0116] The washing machine control method in this application has the following advantages:

[0117] 1. The inner drum of the washing machine can control multiple lifting rib contact surfaces 210 at the same time, and can have multiple contact surface friction structures during a single washing operation, which greatly improves the cleanliness of clothes.

[0118] 2. When the drive assembly 3 uses a connection / disconnection method to realize the rotation of the lifting rib assembly 2 and the lifting rib element 21, the setting of the drive assembly 3 does not hinder the washing operation, which is convenient and quick, and can quickly and effectively change the lifting rib contact surface 210 according to different washing modes.

[0119] 3. The detachability of the lifting rib assembly 2 and the replaceability of the lifting rib element 21 mean that the inner cylinder does not need to be disassembled for replacement of consumables, thus reducing maintenance costs.

[0120] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0121] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0122] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0123] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
