Automatic toilet drainage system

Abstract

This invention relates to an automatic toilet draining device that allows water stored in a toilet tank to be automatically drained into the toilet bowl by tilting the toilet lid covering the top of the toilet bowl towards the toilet tank and then closing it, rather than by pressing a lever. This makes it easy for adults and even children with relatively weak grip strength to drain the water from the toilet tank into the toilet bowl, simplifying the disposal of waste after use. Furthermore, since the water from the toilet tank is drained into the toilet bowl and the waste is discharged to the septic tank simply by closing the easily opened toilet lid, waste disposal after use is possible without the user accidentally pressing the lever, maintaining cleanliness not only inside the toilet bowl but also inside the restroom. With its simple configuration, it can be easily installed and used in existing restroom toilets, resulting in no cost burden, significantly improving ease of installation and use, and can be used with various toilet levers, including not only push-button levers but also flush valves, push valves, and handle levers.

Description

Technical Field

[0001] The present invention relates to an automatic drainage device for a toilet. More specifically, when the lid of the toilet bowl is opened and then closed after use, the water in the toilet tank is automatically drained, and when the lid is completely closed, the water in the toilet tank is stored. The present invention relates to an automatic drainage device for a toilet.

Background Art

[0002] Generally, a toilet is provided with a toilet tank, which is configured to supply water into the toilet bowl after the user has used it and discharge the excrement into the septic tank. The toilet tank is provided with a water supply pipe for supplying water, and when the cleaning lever is operated, a drain lid connected via an operating rod and a connecting chain opens the drain port to supply water to the toilet bowl.

[0003] In the conventional toilet configured as described above, when the user presses down the cleaning lever after use, the operating rod connected to the cleaning lever is lifted. As the operating rod is lifted, the connecting chain connected to the operating rod is pulled upward while pulling up the drain lid connected to the connecting chain to open the drain port, allowing the water stored inside the toilet tank to flow into the toilet bowl and discharging the excrement to the septic tank side.

[0004] Also, after the water stored inside the toilet tank is drained into the toilet bowl through the drain port, the drain lid that was lifted again descends to block the drain port, and at the same time, water is automatically stored inside the toilet tank.

[0005] Such a conventional toilet can prevent contamination and bad odors inside the toilet room and maintain a clean environment inside the toilet room by immediately using the water in the toilet tank to discharge it to the septic tank side after use.

[0006] However, conventional toilet drainage systems have the inconvenience of requiring users to press down the flush lever each time they use the toilet. For children, due to their shorter stature, it is difficult to operate the flush lever, which is mounted relatively high up. Even if they can press down the flush lever, they cannot hold it down for a sufficient amount of time, resulting in the problem that the water in the toilet tank cannot be easily drained into the toilet bowl.

[0007] Furthermore, conventional toilet drainage systems have a problem in that if a user carelessly leaves the restroom without pressing the flush lever, used waste is left inside the toilet bowl, making the restroom unsanitary and causing discomfort to other users.

[0008] Looking at prior art, the "Drainage device for toilet tank" registered as a utility model in the Republic of Korea, No. 20-0229667, has been devised. This device is for a toilet tank that is equipped with a water supply pipe and an opening / closing lid, and a discharge pipe that supplies water to the toilet bowl. A coupling is attached to the upper end of a flush valve formed on one side of the discharge pipe, a tube is attached to the upper end of the coupling, and a connector with an air intake is attached to the other side of the tube, and is connected to the inlet valve and absorption pipe.

[0009] Conventional technologies like this involve a flush valve formed on one side of the discharge pipe, which first reduces noise, and a tube connected to the flush valve made of a soft synthetic resin that secondarily absorbs noise, and is connected to an inlet valve via an absorption tube, thereby preventing noise generated when water is flowing or water is being stored.

[0010] However, in the case of the conventional technology, registered utility model No. 20-0229667 of the Republic of Korea, while it is possible to prevent some noise when flushing, as mentioned above, the inconvenience of having to press the flush lever to flush the water remains unresolved. Furthermore, the problem that children with weak grip strength cannot press the flush lever down sufficiently remains unresolved. Also, since water from the toilet tank will not be drained into the toilet bowl unless the flush lever is pressed down, the problem caused by users not pressing down the flush lever due to carelessness remains unresolved.

[0011] Another example is the "Automatic Toilet Drainage Device" registered as a utility model in the Republic of Korea, No. 20-0294080, which is a toilet comprising a tank that stores a certain amount of water, a main body that uses the water in the tank to drain waste, and an opening / closing means that opens and closes in specific cases to discharge the water in the tank into the main body. The device consists of a sensing means attached to the main body to activate when a load is applied to the main body and then released, a driving means attached to the tank that operates to open and close the opening / closing means, and a control means that controls the operation of the driving means based on an input signal received from the sensing means. When the load applied to the main body is released by the user standing up after using the toilet, the sensing means detects this and the water in the tank is automatically drained.

[0012] However, such conventional technologies require additional sensing, driving, and control devices to be installed in the toilet, which not only imposes a cost burden on consumers, but also poses a problem because automatic drainage is performed by electrical devices, meaning that it is always necessary to have electricity, and therefore it cannot be used in areas where there is no electricity supply or in areas experiencing a power outage.

[0013] Therefore, there is a pressing need for technology that would automatically drain the water from the toilet tank into the toilet bowl when the toilet lid is closed after use, without the user having to manually press down the flush lever each time. [Prior art documents] [Patent Documents]

[0014] [Patent Document 1] Korean Registered Utility Model Publication No. 20-0229667 [Patent Document 2] Korean Registered Utility Model Publication No. 20-0294080 [Overview of the Initiative] [Problems that the invention aims to solve]

[0015] The present invention aims to provide an automatic toilet drainage device that requires no electricity whatsoever, allowing existing toilets to be used without any additional installation, resulting in cost savings, by enabling the use of existing toilets as they are after the user opens the toilet lid and uses the toilet, then closing the lid, which automatically drains the water from the toilet tank into the toilet bowl and discharges the waste into a septic tank, and by completely closing the toilet lid, the toilet tank is refilled with water, allowing for repeated use. [Means for solving the problem]

[0016] As a means to achieve the above objective, the present invention provides an automatic toilet drainage device comprising a toilet comprising: a toilet bowl for the user to use; a toilet lid that covers and blocks the upper end of the toilet bowl or tilts backward from the upper end of the toilet bowl to open the upper end of the toilet bowl; a toilet tank in which water is stored; and a drain lid located at the bottom of the toilet tank, which drains the water stored in the toilet tank into the toilet bowl or blocks the water from draining from the toilet tank into the toilet bowl; a first actuator connected to the drain lid provided at the bottom of the toilet tank; and a first actuator connected to the toilet lid. The toilet bowl lid is tilted towards the toilet tank to open the top of the toilet bowl, and after being attached to the first actuator, when the toilet bowl lid is closed towards the top of the toilet bowl, the first actuator is pulled, causing the drain cover to move up and down along the hinge and open, allowing water from the toilet tank to drain into the toilet bowl. When the toilet bowl lid is completely closed and covers the top of the toilet bowl, the second actuator separates from the attached first actuator, and the drain cover, which was opened by the pulled first actuator, moves down along the hinge, blocking the drainage from the toilet tank.

[0017] Furthermore, the first actuator consists of an actuator wire connected on one side to the drain cover of the toilet tank and located on the other side outside the toilet tank, and a first magnetic body connected to the other side of the actuator wire located on the outside of the toilet tank; the second actuator consists of a second magnetic body that is attached and fixed to the outer surface of the toilet lid but is positioned to correspond to the first magnetic body when it is opened along the hinge to open the upper end of the toilet bowl, and a mounting part that is attached on one side to the second magnetic body and attached on the other side to the outer surface of the toilet lid to attach and fix the second magnetic body to the toilet lid.

[0018] Furthermore, the first or second magnetic material is composed of magnets that are attracted to and adhere to each other by magnetic force when they are in close proximity.

[0019] Furthermore, either the first magnetic material or the second magnetic material is made of a magnet, and the other is made of a metal plate that is attracted to and adheres to the first magnetic material or the second magnetic material, which is made of a magnet.

[0020] Furthermore, the first magnetic material of the first actuator is equipped with a fixing device to which the other end of the actuator wire is attached and secured.

[0021] Furthermore, the first magnetic body of the first actuator is positioned at the center of the upper end of the toilet tank, and when the toilet lid is closed, the operating wire of the first actuator is inserted so as to maximize the force pulling the first actuator towards the first actuator by the second magnetic body of the second actuator attached to the first magnetic body of the first actuator. A positioning device is provided to guide the position of the first magnetic body of the first actuator to be in the center of the toilet tank. The positioning device is provided with a wire retraction section into which the operating wire is inserted, and double-sided tape is provided to attach and fix the positioning device to the toilet tank. [Effects of the Invention]

[0022] In the present invention, instead of the water stored in the toilet tank being discharged by pressing a lever, after the toilet lid covering the upper end of the toilet bowl is tilted toward the toilet tank and then closed again, the water stored in the toilet tank is automatically drained to the toilet bowl side. Thus, not only adults but also children with relatively weak grip strength can easily drain the water in the toilet tank into the toilet bowl. After use, not only can the disposal work of excrement be easily carried out, but also the water in the toilet tank can be drained into the toilet bowl simply by closing the toilet lid that has been easily opened again, and the excrement is discharged to the septic tank side. Therefore, even if the user is careless and does not press the lever, the disposal of excrement after use is possible. Not only the inside of the toilet bowl but also the sanitary condition inside the toilet can be kept clean. With a simple structure, it can be easily installed and used in existing toilets in the toilet. Therefore, there is no cost burden, the installation and usability are greatly improved, and it is applicable not only to the push-type lever of the toilet but also to various toilet levers such as flush valves, push valves, and handle levers.

[0024] In addition to the above objectives, other objectives and features of the present invention will become apparent through the description of embodiments with reference to the accompanying drawings.

[0025] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which this invention pertains. Terms defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and not as ideal or overly formal unless explicitly defined herein.

[0026] In the following, an automatic toilet drainage device according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0027] As shown in the figure, the present invention includes a toilet comprising: a toilet bowl 1 for the user to relieve themselves; a toilet lid 2 that covers and blocks the upper end of the toilet bowl 1, or tilts backward from the upper end of the toilet bowl 1 to open the upper end of the toilet bowl 1; a toilet tank 3 in which water is stored; and a drain lid 4 located at the bottom of the toilet tank 3, which drains the water stored in the toilet tank 3 into the toilet bowl 1, or blocks the water from draining from the toilet tank 3 into the toilet bowl 1. The present invention also includes a first actuator 10 connected to the drain lid 4 provided at the bottom of the toilet tank 3, and a second actuator 20 that is detachable from the first actuator 10.

[0028] In this configuration, the present invention is connected to the toilet lid 2, and when the toilet lid 2 is tilted toward the toilet tank 3 to open the upper end of the toilet bowl 1, the drain cover 4 is attached to the first actuator 10. When the toilet lid 2 is closed toward the upper end of the toilet bowl 1, the first actuator 10 attached to the second actuator 20 is pulled, and the drain cover 4 moves up and down along the hinge, opening the bottom of the toilet tank 3 so that the water from the toilet tank 3 can be drained into the toilet bowl 1. When the toilet lid 2 is completely closed and covers the upper end of the toilet bowl 1, the drain cover 4 is separated from the first actuator 10 attached to the second actuator 20, and the drain cover 4, which was opened by the pulled first actuator 10, moves down along the hinge to block the drainage from the toilet tank 3.

[0029] As a result, after using the toilet, the water from the toilet tank 3 automatically flows into the toilet bowl 1 simply by closing the open toilet lid 2, without having to operate the toilet lever, and the waste is discharged into the septic tank. This makes it easy and simple for anyone to drain the water from the toilet tank 3 into the toilet bowl 1, and makes the waste disposal process after using the toilet much easier.

[0030] Furthermore, simply closing the open toilet lid 2 again automatically drains the water from the toilet tank 3 into the toilet bowl 1. This means that waste can be disposed of after use without the user accidentally pressing the lever, thus maintaining cleanliness not only inside the toilet bowl but also inside the restroom.

[0031] The first actuator 10 of the present invention consists of an actuator wire 11 which is connected on one side to the drain cover 4 of the toilet tank 3 and whose other side is located outside the toilet tank 3, and a first magnetic body 12 which is connected to the other side of the actuator wire 11 located outside the toilet tank 3.

[0032] In this case, the operating wire 11 may be a wire made of iron, or it may be made of a string-like material made of synthetic resin, such as a guitar string.

[0033] The second actuator 20 of the present invention is attached and fixed to the outer surface of the toilet lid 2, and is positioned to correspond to the first magnetic body 12 when the toilet lid 2 is opened along the hinge to open the upper end of the toilet 1, and consists of a mounting part 22 which is attached on one side to the second magnetic body 21 and on the other side to the outer surface of the toilet lid 2 to attach and fix the second magnetic body 21 to the toilet lid 2.

[0034] The second actuator 20 is attached to the upper surface of the toilet lid 2 by attaching the other side of the mounting portion 22, which is attached to the first magnetic body 12, to the toilet lid 2. At this time, the mounting portion 22 that attaches and fixes the first magnetic body 12 to the toilet lid 2 is not limited and can be made of double-sided tape, silicone, or adhesive.

[0035] In this configuration, the present invention connects one side of the operating wire 11 to the drain cover 4, and then positions the first magnetic body 12 of the first operating device 10 on the outside of the toilet tank 3, i.e., on the side of the toilet bowl cover 2, thereby positioning the first magnetic body 12 on the outside of the upper end of the toilet tank 3.

[0036] Furthermore, the second magnetic body 21 can be attached to the toilet lid 2 using the mounting portion 22 of the second actuator 20. In this case, the position of the second magnetic body 21 should be such that it corresponds to the first magnetic body 12 when the toilet lid 2 is opened upwards and the upper end of the toilet bowl 1 is opened, as shown in Figure 3.

[0037] As shown in Figure 3, in the present invention configured in this way, when the toilet lid 2 is opened upwards to relieve oneself, opening the upper end of the toilet bowl 1, the first magnetic material 12 and the second magnetic material 21 are attached to each other by magnetic force.

[0038] After using the toilet, as shown in Figure 4, when the toilet lid 2 is closed towards the upper end of the toilet bowl 1, the second magnetic body 21 descends along the toilet lid 2 that covers the upper end of the toilet bowl 1. At this time, the second magnetic body 21 and the first magnetic body 12, which are attached by magnetic force, are attracted to each other, and the operating wire 11, which is connected to the other end of the first magnetic body 12, is pulled along the first magnetic body 12.

[0039] When the operating wire 11 is pulled in this manner, the drain cover 4, to which one end of the operating wire 11 is connected, is tilted upward, draining the water from the toilet tank. This supplies water into the toilet bowl 1, and the waste is discharged into the septic tank.

[0040] Furthermore, as shown in Figure 5, when the toilet lid 2 is continuously closed toward the upper end of the toilet bowl 1, the first magnetic body 12 of the first actuator 10, which is attached to the second magnetic body 21 of the second actuator 20, is separated from the second magnetic body 21. This is because the actuator wire 11, to which the other end is connected, is limited in length and cannot be pulled any further, thus separating the first magnetic body 12 from the second magnetic body 21.

[0041] When the first magnetic material 12 is separated from the second magnetic material 21 in this way, as shown in Figure 2, one side of the operating wire 11 is connected, and the drain cover 4, which has been tilted upward, is naturally lowered by its own weight, blocking the drainage of water from the toilet tank 3. Water is then resupplied to the toilet tank 3, which has been blocked from draining by the drain cover 4, and stored there.

[0042] In this invention, by opening the toilet lid 2 from the upper end of the toilet bowl 1 or closing the toilet lid 2 to the upper end of the toilet bowl 1 to block the upper end of the toilet bowl 1, the water inside the toilet tank 3 is drained into the toilet bowl 1 while the drainage of the toilet tank 3 is blocked and water is stored, so that after using the toilet, the water inside the toilet tank 3 can be automatically drained into the toilet bowl 1 without having to operate a separate lever.

[0043] The first magnetic body 12 of the first actuator 10 of the present invention may be provided with a fixing device 13 to which the other side of the actuator wire 11 is attached and secured.

[0044] In this case, the fixing device 13 can be welded to the rear surface of the first magnetic body 12, or another fixing device 13 can be attached to the first magnetic body 12 by adhesive, for example, using an adhesive. Since the fixing device 13 is provided on the first magnetic body 12 and the other side of the operating wire 11 is connected to the fixing device 13, when the first magnetic body 12 attached to the second magnetic body 21 is attracted by the action of closing the toilet lid 2, it is possible to prevent the operating wire 11 and the first magnetic body 12 from separating. This makes it easier to open the drain cover 4 inside the toilet tank 3 and drain water into the toilet bowl 1.

[0045] The present invention includes a positioning device 30 into which the operating wire 11 of the first actuator 10 is inserted, and which guides the position of the first magnetic body 12 of the first actuator 10 to be located in the center a of the toilet tank 3.

[0046] At this time, the position setting device 30 is provided with a wire retraction section 31 into which the operating wire 11 is inserted, and double-sided tape 32 is provided to attach and fix the position setting device 30 to the toilet tank 3.

[0047] The wire entry portion 31 of the positioning device 30 may be a through hole provided along the vertical longitudinal direction of the positioning device 30, as shown in Figure 6, or it may be composed of a groove provided along the vertical longitudinal direction of the positioning device 30, as shown in Figure 7.

[0048] As described above, the positioning device 30, which is attached and fixed to the center a of the toilet tank 3, allows the operating wire 11 to be positioned towards the center of the toilet tank 3 along the positioning device 30, which is located at the center a of the upper end of the toilet tank 3 of the toilet bowl 1, when the toilet lid 2 is tilted toward the toilet tank 3 while opening the upper end of the toilet bowl 1, the positions of the first magnetic material 12 and the second magnetic material 21 correspond to each other, greatly improving adhesion. Furthermore, when the toilet lid 2 is closed, the second magnetic material 21 of the second operating device 20, which is attached to the first magnetic material 12 of the first operating device 10, can maximize the force with which the first operating device 10 is attracted.

[0049] Furthermore, even if the drain cover 4 located inside the toilet tank 3 is located on one side of the bottom of the toilet tank 3 rather than in the center, the position setting device 30 can position the first magnetic body 12 of the first actuator 10, which is connected to the other side of the operating wire 11, at the center a of the toilet tank 3. This facilitates the attachment of the first magnetic body 12 and the second magnetic body 21. When the toilet lid 2 is closed, the second magnetic body 21 of the second actuator 20, attached to the first magnetic body 12 of the first actuator 10, pulls the first actuator 10 towards it, greatly improving the ease with which the drain cover 4 located at the bottom of the toilet tank 3 can be opened.

[0050] Figures 9 and 10 show installation examples of the present invention, respectively. As shown in Figure 9, one end of the operating wire 11 can be connected to the push-type valve 101, or as shown in Figure 10, one end of the operating wire 11 can be connected to the handle-type lever 102. Therefore, it can be installed and used regardless of the type or structure of the existing toilet.

[0051] Figure 11 shows another embodiment of the present invention, in which a wire connecting base 14 is provided at the upper end of the drain cover 4, a pressure reducing valve body 15 is provided along the periphery of the wire connecting base 14, and an elastic spring 16 is provided inside the pressure reducing valve body 15, which is compressed when the wire connecting base 14 is raised and lowered by the operation of the operating wire 11, and then quickly returns to its original position when the pulling of the operating wire 11 is released.

[0052] In the present invention configured as described above, when the toilet lid 2 is opened, the first magnetic body 12 of the first actuator 10 and the second magnetic body 21 of the second actuator 20 are attached to each other. After the first magnetic body 12 and the second magnetic body 21 have finished using the toilet, when the opened toilet lid 2 is closed, the operating wire 11 is pulled and the wire connecting base 14 inside the pressure reducing valve body 15 moves up and down, thereby lifting the drain cover 4 and supplying water to the toilet 1 side, and the lifting operation of the drain cover 4 compresses the elastic spring 16.

[0053] Furthermore, when the toilet lid 2 is completely closed, the attached first magnet 12 and second magnet 21 are separated from each other, and the pulling action of the operating wire 11 is released. This releases the compression of the compressed elastic spring 16, and the lifted drain cover 4 is lowered by the rapid restorative force of the elastic spring 16, thereby blocking the drainage.

[0054] Furthermore, as shown in Figure 12, the first magnetic material 12 of the first actuator 10 may be attracted to the periphery of the actuator wire 11, thereby providing a guide tube 17 that can guide the pulling force when the actuator wire 11 is pulled.

[0055] Furthermore, a pressure-reducing water hole 18 may be provided at the lower end of the pressure-reducing valve body 15, and the pressure-reducing water hole 18 may be directly connected to the toilet bowl via a drainage channel or outlet pipe E.

[0056] Furthermore, the operating wire 11 is provided with a stopper 40 that can be attached to the upper end of the toilet tank 3 so that the first magnetic body 12 and the second magnetic body 21 can be easily and simply separated when the toilet lid 2 is closed.

[0057] With the stopper 40 provided in this manner, when the second magnetic body 21 is lowered along the toilet lid 2 by the action of closing the toilet lid 2, the range in which the first magnetic body 12 attached to the second magnetic body 21 is attracted may be limited, and the first magnetic body 12 and the second magnetic body 21 may be easily and simply separated.

[0058] In the present invention, the first magnetic body 12 or the second magnetic body 21 may be composed of magnets that are attracted to and adhere to each other by magnetic force when they are in close proximity. Alternatively, either the first magnetic body 12 or the second magnetic body 21 may be composed of a magnet, and the other may be composed of a metal plate that is attracted to and adheres to the first magnetic body 12 or the second magnetic body 21, which is composed of a magnet.

[0059] Furthermore, in the present invention, the operating wire 11 of the first actuator 10 located on the outside of the toilet tank 3 is in close contact with the toilet tank lid 3-1 of the toilet bowl, so in the process of attaching and separating the first magnetic material 12 and the second magnetic material 21 connected to the operating wire 11, there is a possibility that problems may arise due to excessive contact when the operating wire 11 should not be pulled to the outside of the toilet tank 3 or any further.

[0060] Therefore, as shown in Figure 13, by adhering an elastic material 3-2 such as silicone to the inside of the toilet tank lid 3-1 so that the operating wire 11 is separated from the toilet tank lid, the process of separating the first magnetic material 12 and the second magnetic material 21, which are connected to the operating wire 11, after they have been attached can be made smoother.

[0061] Since the elastic member 3-2 has the function of creating a gap so that the operating wire 11 can move smoothly, it may be adhered to all three corners inside the toilet tank lid 3-1, or it may be adhered to only one side.

[0062] Furthermore, in the present invention, the actuating wire 11 may move from side to side during the process in which the first magnetic body 12 and the second magnetic body 21, which are connected to the actuating wire 11, are attached and then separated. Also, the stopper 40 may bounce back due to its weight. In such cases, the position of the first magnetic body 12 is not fixed, making it difficult for the second magnetic body 21 to attach accurately, and automatic drainage may not be easily achieved. Therefore, as shown in Figure 14, by inserting an elastic material tube 11-1 connected to the actuating wire 11, side-to-side movement and bounce back due to recoil can be prevented.

[0063] The operating wire tube 11-1 described above is not limited by material, and can be made of any flexible and easily bendable material. The operating wire tube 11-1 is used by attaching one end to the inside of the toilet tank 3 and the other end to the outside of the toilet tank 3 with double-sided tape or the like.

[0064] Furthermore, since the size and structure of toilets differ in each household, in the process of separating the first magnetic material 12 and the second magnetic material 21 after they have been attached, the mechanical relationship between the weight of the first magnetic material 12 and the weight of the stopper 40 becomes very close. Therefore, if the first magnetic material 12 is heavy, the stopper 40 also needs to be heavy, and if the first magnetic material 12 is light, the weight of the stopper 40 needs to be adjusted accordingly. Thus, since the weight of the stopper 40 needs to be adjusted according to each case, a form in which the weight of the stopper 40 can be adjusted would be more suitable for the purpose of the present invention. As an example, the stopper 40 may be in the form of an openable and closable cylindrical body filled with iron balls or the like. In each household, one method is to put iron balls into this cylindrical body and adjust the weight of the stopper 40 by adding or removing iron balls as needed.

[0065] As described above, the present invention has been explained based on specific components and other details, as well as limited embodiments and drawings. These are provided to aid in a more general understanding of the present invention, and the present invention is not limited to the embodiments described above. Various modifications and variations can be made from these descriptions by a person with ordinary skill in the art to which the present invention belongs.

[0066] Therefore, the concept of the present invention should not be interpreted as being limited to the embodiments described, and it should be understood that the scope of the concept of the present invention includes not only the claims described below, but also all that are equivalent to or have equivalent variations of these claims.
