Description

Technical Field

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

[0002] With the advancement of science and technology, people's living standards are getting higher and higher, and daily housework is gradually being replaced by machines instead of manual labor. As common household appliances in daily life, washing machines, shoe washers and other clothing processing equipment have brought great convenience to people's lives.

[0003] However, when using laundry processing equipment, the viewing window and sealing window gasket often become contaminated with lint. If not cleaned promptly, this not only obstructs vision but can also cause mold and odor. Some machines are equipped with a spray pipe to rinse the viewing window and sealing window gasket. However, when laundry processing equipment is used for a certain period of time, the spray pipe outlet is easily clogged with sand and scale, rendering the rinsing effect ineffective.

[0042] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] Before introducing the clothes treating apparatus provided by the present invention, the principle that scale deposition is easily generated in the water inlet assembly of the clothes treating apparatus is first explained.

[0047] Washing water for laundry treatment equipment typically comes from tap water. Since tap water generally contains dissolved calcium and magnesium ions, the harder the water, the higher the calcium and magnesium ion content. Therefore, when water is no longer flowing into the laundry treatment equipment, the inlet valve upstream of the shower pipe closes, and the residual water in the shower pipe immediately stops flowing. When hard tap water remains open and static in the laundry treatment equipment's inlet pipe for a long time, it absorbs gases like carbon dioxide and sulfur dioxide from the air. These carbon dioxide and sulfur dioxide dissolve in water, producing carbonate and sulfate ions. These ions react with calcium and magnesium ions to produce water-insoluble precipitates such as calcium carbonate, magnesium carbonate, and calcium sulfate. These precipitates accumulate and form scale.

[0048] Therefore, to prevent scale buildup, one approach is to reduce the amount of calcium and magnesium ions in the water, for example by using water softening. Another approach is to reduce the amount of carbon dioxide and sulfur dioxide that cause calcium and magnesium ions to precipitate, which is more difficult. Another approach is to reduce the time it takes for hard water to combine with carbon dioxide and sulfur dioxide, allowing the water to dry before they can react. Even if white powder precipitates, it is readily soluble in water, calcium chloride and magnesium chloride, and will be quickly washed away during the next flush.

[0049] Furthermore, when a bubbler is installed at the shower outlet, water will remain in the inlet pipe for a long time due to the thin inlet pipe, the surface tension between the filter and the water, and the influence of atmospheric pressure. The bubbler outlet is located closest to the air, and surface tension also makes it easy for a water film to form on the filter, which is most likely to absorb acidic gases and deposit scale. Over time, this can cause the filter to become clogged, preventing the spray of bubbling water.

[0050] Figure 1A 、 Figure 1B and Figure 2A 、 Figure 2B FIG2 shows a schematic structural diagram of a clothes processing device 10 provided according to an exemplary embodiment of the present invention. The clothes processing device 10 is a washing machine, a washer-dryer, a shoe washer, etc., and the present invention is not limited thereto.

[0051] like Figure 1A 、 Figure 1B and Figure 2A 、 Figure 2B As shown, the laundry processing device 10 includes a housing 100, an outer drum 200, an inner drum, and a dispenser box 300 disposed within the housing 100. The front side of the housing 100 is provided with a laundry inlet and a door 400 for opening and closing the laundry inlet. The door 400 is provided with an observation window, and a sealing window gasket 410 is provided between the laundry inlet and the outer drum 200. The inner drum is connected to a drive unit for driving the inner drum to rotate.

[0052] The top of the outer tub 200 is connected to the dispenser box 300 via a curved water seal tube 310, which is used to dispense laundry treatment agent and wash water into the outer tub 200. Furthermore, a one-way air guide structure 220 is installed on the air vent 210 of the outer tub 200, conducting air from the interior of the outer tub 200 to the exterior. This one-way air guide structure 220 allows air to flow from the interior of the outer tub 200 to the exterior, but prevents air from outside the outer tub 200 from flowing back into the outer tub 200. It will be understood that during or after the laundry treatment agent and wash water are dispensed into the outer tub 200, the space in the outer tub 200 and the space in the dispenser box 300 are separated by the water in the curved water seal tube 310.

[0053] The housing 100 is also provided with a drainage assembly 500 connected to the outer cylinder 200 for draining water from the outer cylinder 200. The drainage assembly 500 adopts an upper drainage structure. It is understood that after the drainage process is completed, the water remaining in the drainage assembly 500 with the upper drainage structure can isolate the space of the outer cylinder 200 from the outside space. As an example, the drainage assembly 500 includes a drainage pump 510, a water diversion pipe 520, and a drainage pipe 530. The water diversion pipe 520 is connected between the outer cylinder 200 and the inlet of the drainage pump 510, and the drainage pipe 530 is connected to the outlet of the drainage pump 510.

[0054] The laundry processing device 10 further includes a water inlet assembly 600, which includes a water inlet pipe 640 and a spray pipe 610. The water inlet pipe 640 is configured to provide dilution and rinsing water to the dispenser box 300, and the spray pipe 610 is configured to provide rinsing water to the observation window and / or the sealing window gasket 410. The spray pipe 610 is connected to the dispenser box 300 via an air duct 620. It should be noted that the air duct 620 being connected to the dispenser box 300 refers to the air duct 620 being connected to the non-water-submerged space of the dispenser box 300. In other words, the air duct 620 is connected to a portion of the dispenser box 300 that is above the highest water level.

[0055] In the above embodiment, when a user processes clothes using the laundry treatment device 10, closes the door 400 of the laundry treatment device 10, and begins to let water in, the outer tub 200 is effectively a closed cavity except for the air vent 210, due to the provision of the sealing window gasket 410, the curved water seal tube 310, and the drainage assembly 500 of the upper drainage structure. Therefore, when water enters the outer tub 200 through the water inlet pipe 640 and simultaneously through the spray pipe 610, the gas space within the outer tub 200 is compressed, increasing the internal pressure of the outer tub 200. The one-way air guide structure 220 is then turned on, and the gas inside the outer tub 200 is discharged through the air vent 210, maintaining a pressure balance inside and outside the outer tub 200. In addition, the gas in the non-water-immersed space of the dispenser box 300 enters the spray pipe 610 through the air duct 620, injecting gas into the water flow, increasing the amount of air in the water, which is conducive to the formation of bubble water. The bubbles have an explosion effect when they burst, which is more effective in cleaning firmly attached lint stains, and thus has a better cleaning effect on the observation window and the sealing window gasket.

[0056] When water is introduced into the outer cylinder 200 through the water inlet pipe 640 and the spray pipe 610 stops introducing water at the same time, the spray pipe 610 is connected to the non-water-immersed space of the distributor box 300 through the air guide pipe 620 to form an air guide channel. On this basis, the one-way air guide structure 220 is closed, and the water entering the outer cylinder 200 through the water inlet pipe 640 will displace an equal amount of gas. This part of the gas enters the non-water-immersed space in the distributor box 300 through the spray pipe 610 and the air guide pipe 620. This not only maintains the pressure balance inside and outside the outer cylinder 200, but also avoids the occurrence of scale deposition due to residual water flow in the spray pipe 610.

[0057] After the water intake is completed and the washing begins, the clothes are thrown up and down in the inner drum, causing air disturbance in the outer drum 200. Air flow will also continuously flow through the air duct 620 and the spray pipe 610, so that the gas can form a two-way flow in the spray pipe 610 and the air duct 620, drying the water film formed at the outlet of the spray pipe 610 and avoiding the formation of scale deposition at the outlet of the spray pipe 610.

[0058] After washing is completed and drainage begins, the drain pump 510 continuously discharges water from the outer drum 200 through the drain pipe 530 to the outside of the clothing processing device 10. As the water in the outer drum 200 decreases, in order to balance the air pressure, an equal amount of drainage volume of air will enter the outer drum 200. Due to the presence of the bent water seal tube 310 and the one-way air guide valve 220, air can only enter the outer drum 200 through the air guide pipe 620 and the spray pipe 610. These gases will also dry up the water film formed at the outlet of the spray pipe 610, thereby further preventing the residual water at the outlet of the spray pipe 610 from accumulating for a long time and absorbing carbon dioxide, generating precipitation and causing scale accumulation.

[0059] In addition, the spray pipe 610 is connected to the non-water-immersed space of the distributor box 300 through the air guide pipe 620. When backflow occurs in the spray pipe 610, the water flow can be diverted to the distributor box 300 and then into the outer tube 200 to prevent water overflow.

[0060] In some embodiments, as Figure 1A and Figure 1B As shown, the one-way air guide structure 220 includes a truncated cone-shaped fixed bracket 221 embedded in the air vent 210. A truncated cone-shaped sealing valve disc 222 is movably disposed within the fixed bracket 221 for opening and closing the air vent 210. It will be appreciated that to facilitate the discharge of gas from the outer tube 200, the air vent 210 is typically located at the top of the outer tube 200.

[0061] Specifically, when the internal pressure of the outer cylinder 200 is greater than the external pressure, under the action of the air pressure, the frustum-shaped sealing valve disc 222 moves away from the vent hole 210, so that the vent hole 210 is opened. Figure 1BWhen the internal pressure of the outer cylinder 200 is lower than the external pressure, under the action of air pressure and gravity, the frustum-shaped sealing valve disc 222 moves toward the direction of the vent hole 210, closing the vent hole 210. Figure 1A .

[0062] As an example, to prevent excessive positive pressure within the outer tube 200, the sealing valve disc 222 can be designed and manufactured using a relatively low-density material. This allows the vent 210 to be promptly opened when the gas flow in the air guide tube 620 and the spray pipe 610 decreases. It should be noted that the weight of the sealing valve disc 222 can be adjusted based on actual needs and is not a limitation of the present invention.

[0063] Alternatively, an elastic valve sheet is fixedly provided on the side of the bracket facing away from the air vent 210, and a crack is provided at the center of the elastic valve sheet. The bracket has a through hole to allow gas to pass through and act on the elastic valve sheet to deform the elastic valve sheet in the direction from the inside of the outer tube 200 to the outside, and to prevent the elastic valve sheet from deforming in the direction from the outside of the outer tube 200 to the inside, so that the crack forms a one-way air guide channel from the inside of the outer tube 200 to the outside.

[0064] Specifically, when the internal pressure of the outer tube 200 is greater than the external pressure, under the action of the gas pressure, the center of the elastic valve plate moves away from the air vent 210, the crack is stretched, and the air vent 210 is opened. When the internal pressure of the outer tube 200 is less than the external pressure, under the action of the gas pressure and the rebound force, the center of the elastic valve plate moves toward the air vent 210, the crack closes, and the air vent 210 is closed.

[0065] In some embodiments, as Figure 2A and Figure 2B As shown, the one-way air guide structure 220 includes a cover 223 for closing the air hole 210 , and the cover 223 is pivotally connected to the outer wall of the outer cylinder 200 via a pivot shaft 224 .

[0066] Specifically, when the internal pressure of the outer cylinder 200 is greater than the external pressure, the air pressure overcomes the gravity of the cover 223, causing the cover 223 to rotate away from the vent 210, so that the vent 210 is opened. Figure 2B When the internal pressure of the outer cylinder 200 is lower than the external pressure, the gas pressure and gravity cause the cover 223 to move toward the vent hole 210, closing the vent hole 210. Figure 2A .

[0067] It should be noted that, since the outer wall of the outer cylinder 200 is an arc-shaped structure, the above-mentioned cover 223 can be set to be consistent with the extension direction of the outer cylinder 200, so as to reduce the amount of air leakage at the air hole 210 when the cover 223 closes the air hole 210.

[0068] In the above solution, by setting the one-way air guide structure 220 as a structure combining a bracket and an elastic valve plate / sealing valve plate 222 or a structure combining a cover 223 and a pivot shaft 224, a mechanical structure is used to achieve one-way air guidance from the inside of the outer tube 200 to the outside, and the structure is simple and easy to implement.

[0069] In some embodiments, the water inlet pipe 640 and the spray pipe 610 are both connected to a water inlet valve 700 of the laundry processing apparatus. The water inlet valve 700 employs multiple solenoid valves to control the opening and closing of the water inlet pipe 640 and / or the spray pipe 610. Alternatively, the water inlet valve 700 employs a three-way solenoid valve to control the opening and closing of the water inlet pipe 640 and / or the spray pipe 610.

[0070] Figure 3 A schematic diagram of the internal structure of an air guide tube 620 and a joint tube 612 according to an exemplary embodiment of the present invention is shown; Figure 4 Shown Figure 3 AA section view of the center structure.

[0071] like Figure 3 and Figure 4 As shown, a mounting hole is opened on the pipe wall of the spray pipe 610, and the air guide pipe 620 is fixedly connected to the spray pipe 610 through the mounting hole. The first end of the air guide pipe 620 is located inside the spray pipe 610, and the extension direction of the first end of the air guide pipe 620 is consistent with the water inlet direction of the spray pipe 610. The second end of the air guide pipe 620 is connected to the non-water-immersed space of the distributor box 300.

[0072] In some embodiments, as Figure 5 As shown, the end of the spray pipe 610 is further connected to a bubbler 630, wherein the bubbler 630 includes a jet pipe 631 and a bubble pipe 632. The jet pipe 631 is connected to the water outlet of the spray pipe 610, and the diameter of the jet pipe 631 matches the diameter of the spray pipe 610. The jet pipe 631 is provided with a jet nozzle 6312 that gradually narrows along the water outlet direction. Figure 5 As shown, the jet nozzle 6312 is used to increase the solubility of gas in water and the water flow rate. The bubble tube 632 is connected to the jet tube 631. The bubble tube 632 is provided with a filter 6324, which is used to precipitate the dissolved gas in the water to form microbubble water.

[0073] Through the above solution, when the water inlet valve 700 is opened and water enters the spray pipe 610, the water flows from the spray pipe 610 to the Figure 1A 、 Figure 1B 、 Figure 2A 、 Figure 2B As the water flows from the right side to the left side, negative pressure is generated at the first end of the air duct 620, drawing gas from the dispenser box 300 through the air duct 620 and into the spray pipe 610. As the water flows, air is entrained and mixed into the water, creating bubbles within the water and increasing the air solubility. This also accelerates the water flow. This is because the kinetic energy per unit length of water is constant during flow. The inclusion of bubbles in the water is equivalent to a decrease in the density of this portion of the water, resulting in a faster flow and a greater spray distance.

[0074] In addition, the present invention provides an air guide pipe 620 in the spray pipe 610, and the air guide pipe 620 is located in the internal part of the spray pipe 610, and its extension direction is consistent with the water inlet direction of the spray pipe 610. When the water inlet valve 700 is closed, the water in the spray pipe 610 that has not flowed out continues to flow forward under the action of inertia. At this time, the gas will enter the spray pipe 610 through the air guide pipe 620. Since there is no negative pressure restraint, the water in the pipeline will continue to flow downstream unimpeded under the action of inertia and / or gravity until it flows out of the filter 6324.

[0075] like Figure 5 As shown, as water flows through the jet nozzle 6312 in the jet tube 631, it compresses the water and increases its pressure. This pressure also increases the gas solubility in the water. This pressurizes the air entering through the air duct 620 and the bubbles that remain undissolved in the water, further increasing the amount of air dissolved in the water. After the water is compressed by the jet tube 631, its outflow velocity increases. After passing through the filter 6324 in the bubbler tube 632, the water is blocked at multiple points. The pressure drops dramatically after the blockage points, allowing the dissolved gases in the water to be released as bubbles, thus forming microbubble water.

[0076] In detail, after the water flows through the obstacle, the pressure behind the obstacle decreases, and the gas dissolved in the water will quickly overflow. Due to the surface tension of the water molecules, the water molecules surround the gas, forming bubbles. In other words, the lower the pressure behind the obstacle is compared to the pressure before the obstacle, the more bubbles will overflow. In addition, the more gas dissolved in water, the more precipitation will occur, and the higher the pressure, the easier it is for the gas to dissolve in water. Therefore, the present invention uses the air guide tube 620 to introduce gas into the spray pipe 610, and allows the gas to naturally dissolve in water in the longer pipe, and then pressurizes it through the jet tube 631 to allow more gas to dissolve in water. The pressurized water flow rate becomes faster, and after encountering the filter 6324 in the bubble tube 632, the pressure difference on both sides of the filter 6324 in the direction of water flow is larger, making it easier for gas to overflow and generate bubbles.

[0077] However, since the mesh of the filter 6324 in the bubble tube 632 is smaller and the surface tension of water molecules is stronger, it is easier for a water film to form on the filter 6324 after the water supply stops. Therefore, the above scheme of the present invention connects the spray pipe 610 to the non-water-immersed space of the distributor box 300 through the air duct 620, and at the same time utilizes the one-way air guide structure 220 at the air hole 210, so that when no water enters the spray pipe 610, an air flow is formed in the spray pipe 610 and the air duct 620 to dry the water film formed on the filter 6324, thereby preventing the water film from absorbing carbon dioxide, sulfur dioxide and other gases in the air to form scale and render the filter 6324 ineffective.

[0078] In some embodiments, as Figure 3 As shown, the spray pipe 610 includes a main spray pipe 611 and a joint pipe 612 detachably connected to the main spray pipe 611. The mounting holes are provided on the joint pipe 612. This allows the joint pipe 612 and the air guide pipe 620 to be modularized and used as a single, highly reliable component. During use, the air guide pipe 620 can be connected to the joint pipe 612 and then connected to the main spray pipe 611.

[0079] Furthermore, if this integral component is required in a pipeline, such as when the main shower pipe 611 is directly connected to a user's home faucet, the main shower pipe 611 can be cut and the integral component inserted into the cut ends. For example, annular ribs 6121 can be provided on the outer walls of the two ends of the joint pipe 612. The ends of the joint pipe 612 are then inserted into the main shower pipe 611, with the main shower pipe 611's opening extending beyond the annular ribs 6121. The joint pipe 612 can then be secured with a pipe clamp to prevent it from loosening.

[0080] As an example, Figure 3As shown, for ease of manufacturing and installation, the air duct 620 is in an inverted L-shape near the connector tube 612. The portion of the air duct located within the connector tube 612 (the horizontal section in the figure) is located at the axis of the connector tube 612, while the portion located outside the connector tube 612 (the vertical section in the figure) passes through a mounting hole in the wall of the connector tube 612 and is connected to the distributor box 300. Alternatively, the portion of the air duct located within the connector tube 612 may be an inclined section.

[0081] In some embodiments, as Figure 3 and Figure 4 As shown, the connector tube 612 has a boss 6122 formed on its wall, and the mounting hole is a stepped hole 6123 that passes through the boss 6122. The air duct 620 is securely connected to the boss 6122, with a sealing gasket 622 disposed between the air duct 620 and the stepped hole 6123. This facilitates mass production and assembly of the integral component consisting of the connector tube 612 and the air duct 620.

[0082] As an example, Figure 3 and Figure 4 As shown, a truncated cone-shaped boss 6122 is provided at the bottom of the connector tube 612. A stepped hole 6123 is provided perpendicularly through the boss 6122. A sealing gasket 622 is provided in the stepped hole 6123 to prevent liquid leakage at the interface. The inner diameter of the stepped hole 6123 increases radially from the inside outward. In addition to accommodating the sealing gasket 622, the stepped hole 6123 also facilitates insertion of the curved air duct 620 into the connector tube 612. It should be noted that when the first end of the air duct 620 is angled, the stepped hole 6123 can also be adapted to be an inclined stepped hole 6123 that extends obliquely through the boss 6122. Alternatively, the stepped hole 6123 can remain vertical but with a larger diameter, with the sealing gasket 622 still installed vertically, with the vertical portion of the air duct 620 now angled to pass through the sealing gasket 622.

[0083] In some embodiments, to position the air duct 620 for installation, a flange ring 621 can be provided on the air inlet section of the air duct 620. The height of the flange ring 621 should ensure that the air outlet section of the air duct 620 is aligned with the axis of the connector pipe 612. To ensure that the air outlet section of the air duct 620 is coaxial with the connector pipe 612, multiple through holes are provided on the flange ring 621, and corresponding blind holes are provided on the boss 6122. After assembly and alignment, the flange ring 621 can be fastened with screws 623 to ensure that the two cannot become loose. This also ensures that the two are always coaxial. Since liquids have viscous resistance, the closer to the pipe wall, the greater the resistance, the slower the water flow. Conversely, the closer to the center of the pipe, the faster the water flow, thus maintaining air conduction efficiency.

[0084] In some embodiments, as Figure 5 As shown, the jet nozzle 6312 can be manufactured integrally with the jet tube 631. The jet nozzle 6312 is a nozzle with a smooth transition and gradually narrowing, which can pressurize and speed up the water flowing through it. The pressurization process can increase the solubility of gas in water. The higher the solubility of air in water, the easier it is to generate bubbles and more bubbles can be generated. After the accelerated water flow encounters a mesh obstruction structure such as the filter 6324, the pressure drops sharply, which can precipitate more air and generate more bubbles. Both ends of the jet tube 631 are provided with a second threaded section 6311 or other connection limiting structure, such as a rib or groove, which is detachably connected to the outlet of the main spray pipe 611.

[0085] In some embodiments, the filter 6324 is tilted within the bubble tube 632. For example, the angle α between the filter 6324 and the water flow direction of the bubble tube 632 ranges from 5° to 60°. Preferably, α ranges from 10° to 40°. Because the filter 6324 is tilted, the area of ​​the liquid sprayed onto the filter 6324 is increased, thereby generating more bubbles.

[0086] In some embodiments, the inner wall of the bubble tube 632 is circumferentially provided with a step groove 6321 that is elliptical when viewed from its vertical direction, and the filter 6324 is obliquely clamped on the step groove 6321; the jet tube 631 is inserted into the bubble tube 632, and a limiter 6326 is embedded between the end of the jet tube 631 and the filter 6324.

[0087] Specifically, the bubble tube 632 is a straight tube with an inclined stepped groove 6321 provided on its inner wall for retaining the elliptical filter 6324. A retaining member 6326 is also provided within the stepped groove 6321 for securing the filter 6324. For example, the retaining member 6326 may be a standard hollow cylinder at the top with the bottom portion cut away to form an elliptical retaining tube.

[0088] The inner diameter of the limiter 6326 matches the maximum inner diameter of the jet tube 631 and the minimum inner diameter of the bubble tube 632, so that there is no additional obstruction to the water flow. At the same time, a first threaded section 6322 or other pipeline connection structure, such as a rib, a groove, a buckle and other structures, is provided on the top of the bubble tube 632 for detachable connection with the jet tube 631. The bubble tube 632 should match the connection structure of the jet tube 631. After the jet tube 631 and the bubble tube 632 are installed, the jet tube 631 presses tightly against the limiter 6326, indirectly fixing the filter screen 6324; the filter screen 6324 is installed at a larger angle, which can prevent the mud and sand particles from clogging and adhering to the filter screen 6324, and can guide the mud and sand particles to move to the lower angle.

[0089] Optionally, the filter screen 6324 is provided with a sand discharge hole 6325 at a downstream position along the water flow direction, which can discharge the sediment collected there after being filtered by the filter screen 6324. In addition, the filter screen 6324 is tilted to increase the water flow area and generate more bubbles.

[0090] In addition, the present invention stipulates that the jet tube 631 is detachably connected to the main spray pipe 611, and the bubble tube 632 is detachably connected to the jet tube 631. Therefore, even if larger particles of mud and sand accumulate on the jet nozzle 6312 or the filter screen 6324, it is convenient to disassemble the various components of the water inlet assembly 600 for cleaning or replacement.

[0091] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
