2. Description of the Related Art In general, a vacuum cleaner is a household appliance that sucks small garbage or dust and fills a dust bin in a product by suctioning air using electricity, and is generally referred to as a vacuum cleaner.

Such a vacuum cleaner may be divided into a manual cleaner in which the user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves. Manual vacuum cleaners may be classified into canister-type cleaners, upright cleaners, handy-type cleaners, stick-type cleaners, and the like, depending on the type of cleaner.

In the past, canister-type vacuum cleaners were often used in household cleaners, but recently, a hand-held vacuum cleaner and a stick cleaner, which are convenient to use by providing a dust container and a cleaner body, are increasingly being used.

The canisty type vacuum cleaner is connected to the main body and the suction port by a rubber hose or pipe, and in some cases, it can be used by inserting a brush into the suction port.

The hand-held vacuum cleaner maximizes portability, and although it is light in weight, there may be restrictions on the cleaning area while sitting due to its short length. Therefore, it is used to clean localized places such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used while standing, so you can clean without bending your back. Therefore, it is advantageous for cleaning while moving a large area. If a hand-held vacuum cleaner cleans a narrow space, the stick-type vacuum cleaner can clean a wider space than that, and can clean a high place that cannot be reached by hand. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

However, in the stick cleaner, the capacity of the dust bin for storing the collected dust is small, so that the user has to empty the dust bin every time.

The prior patent document includes a vacuum cleaner including a dust collector in which foreign substances are collected, and a docking station connected to the dust collector to remove foreign substances collected in the dust collector, and the dust collector is docked to the docking station. The docking station is configured to include a suction device for sucking foreign substances and internal air in the dust collector docked in the docking station.

In addition, the prior patent document is configured to include a collecting unit for collecting foreign substances inside the docking station.

However, the prior patent document has a problem that, after the suction of the suction device (suction fan) is finished, foreign substances that may stick to the periphery of the dust collector during the suction process cannot be removed.

Therefore, when the user uses the vacuum cleaner again after the suction process of foreign substances is finished, the user has no choice but to touch the foreign substances (hereinafter, residual dust) that are exposed while sticking around the dust collector, and the user It is inconvenient to have to remove the residual dust directly using a wet tissue or the like.

In addition, when these foreign substances are deposited inside the docking station, there is a problem that the inside of the docking station is contaminated.

Meanwhile, as will be described later, the suction pipe 700 of the cleaner station 1 may extend vertically inside the housing 100 . Accordingly, the dust present in the dust bin 2600 by the suction force of the dust collecting motor 200 moves in the horizontal direction along the dust bin body 2610, and as it enters the suction pipe 700, the flow direction is changed in the vertical direction to change the flow direction of the housing 100 ) is collected in the dust storage module 300 accommodated in the lower inside.

That is, the dust in the dust container 2600 of the cleaner 2 may be collected by the dust storage module 300 of the cleaner station 1 by the action of the suction force and gravity of the dust collecting motor 200 .

Through this configuration, it is possible to remove the dust in the dust bin without a separate operation by the user, thereby providing user convenience. In addition, it is possible to eliminate the hassle of the user having to empty the dust bin every time. In addition, it is possible to prevent dust from scattering when the dust bin is emptied.

More specifically, the push protrusion 511 may be formed to protrude upward in the long axis direction of the housing at a position opposite to the coupling lever 2630 provided to open the discharge cover 2620 of the cleaner 2 .

The cover opening unit 500 may further include a protrusion support 512 , a protrusion neck 513 , and a gear coupling block 514 .

At this time, the protrusion support 512 is coupled to the lower end of the push protrusion 511 and linearly reciprocates together with the push protrusion 511 , and the lower surface of the protrusion support 512 is flat of the second coupling part 112 . It is disposed to face the surface (112a) and the protrusion support (512) can linearly reciprocate on the flat surface (112a).

The protrusion neck 513 may be coupled to the lower surface of the protrusion support 512 and disposed in the protrusion neck insertion hole 112aa. The protrusion neck 513 may be coupled between the protrusion support 512 and the gear coupling block 514 . That is, the protrusion support 512 is coupled to the upper portion of the protrusion neck 513 and the gear coupling block 514 is coupled to the lower portion of the protrusion neck 513 to push the protrusion 511 to the upper portion of the flat surface 112a. ) and the protrusion support 512 are exposed and a gear coupling block 514 may be disposed under the flat surface 112a. The protrusion neck 513 may be formed to have a narrower width than the protrusion support 512 and the gear coupling block 514 .

The gear coupling block 514 is disposed under the flat surface 112a and may reciprocate linearly by the movement of the cover opening gear 520 .

The cover opening motor may provide power for linearly reciprocating the push protrusion 511 to the cover opening gear 520 . More specifically, the cover opening gear 520 is coupled with the cover opening motor, and by using the power of the cover opening motor, the push projection 511, the projection support 512, the projection neck 513, and the gear coupling block 514. can be moved together. The cover opening gear 520 is meshed with the first cover opening gear 521 and the first cover opening gear 521 receiving rotational power from the shaft of the cover opening motor and transmitting a linear reciprocating motion to the push protrusion 511. A second cover opening gear 522 may be included.

In this case, the first cover opening gear 521 may be formed of a pinion gear, and the second cover opening gear 522 may be formed of a rack gear.

In other words, when the main body of the cleaner 2 is fixed to the coupling part 110 , the cover opening motor moves the push protrusion 511 through the cover opening gear 520 and opens the discharge cover 2620 to open the dust container body. (2610).

The cleaner station 1 according to the embodiment of the present invention may further include a door unit 600 .

Referring to FIG. 5 , the door unit 600 may include a door 610 , a door arm 620 , and a door motor 630 .

The door 610 may be hinge-coupled to the coupling part 110 , and may be opened in a direction in which the discharge cover 2620 is opened to communicate the outside of the housing 100 with the suction pipe 700 . More specifically, the door 610 is coupled to the door hinge 605 disposed on the third coupling part 113 to be rotatable around the door hinge 605 .

In a state where the door 610 blocks the dust passage hole 113a to close the inside and outside of the housing 100 , when the door arm 620 pulls the door 610 , the door 610 opens the vacuum cleaner station 1 ) can be rotated toward the inside of the housing 100 . Meanwhile, when the door arm 620 pushes the door 610 , the door 610 may rotate toward the outside of the cleaner station 1 .

The door motor 630 may provide power to rotate the door 610 to the door arm 620 . Specifically, the door motor 630 may rotate the door arm 620 in a forward or reverse direction. Here, the forward direction may mean a direction in which the door arm 620 pulls the door 610 toward the inside of the housing 100 . Also, the reverse direction may mean a direction in which the door arm 620 pushes the door 610 toward the outside of the housing 100 .

The door arm 620 is coupled to the door 610 to open and close the door 610 , and serves to connect the door 610 and the door motor 630 . The door arm 620 may open and close the door 610 using power generated from the door motor 630 .

Hereinafter, an arrangement of the bypass hole 710 formed in the suction pipe 700 and a specific structure for removing residual dust, which is a problem of the present invention, will be described with reference to FIGS. 4 and 6 .

The cleaner station 1 may further include a suction pipe 700 .

First, referring to FIG. 6 , the suction pipe 700 is accommodated in the housing 100 and disposed in the vertical direction, and air containing the dust escaping from the dust container 2600 of the cleaner 2 can flow. It may be provided to provide a space (S1). That is, when the cleaner 2 is coupled to the cleaner station 1 , the dust container 2600 may be disposed at the open upper end of the suction pipe 700 . At this time, since the open lower end of the suction tube 700 is coupled to the dust storage module 300 , when the discharge cover 2620 is separated from the dust container body 2610 , the dust inside the dust container body 2610 is removed from the suction tube 700 . ) through, the dust may be collected by the storage module 300 .

Also, the open upper end of the suction pipe 700 may be defined as a dust passage hole 113a. As described above, the dust passage hole 113a may serve as a main hole for sucking dust from the dust container 2600 into the housing 100 .

A bypass hole 710 may be provided in the suction pipe 700 to remove residual dust. At this time, referring to FIG. 4 , the bypass hole 710 has a push protrusion 511 on the suction pipe 700 in a direction in which the push protrusion 511 presses the coupling lever 2630 coupled to the dust container body 2610 with the push protrusion 511 and It is provided at a position facing, and may be provided in a form penetrating the inside and the outside of the suction pipe 700 . The bypass hole 710 may be provided, for example, in the form of a horizontal long hole. More specifically, the bypass hole 710 may be formed through the suction pipe 700 at the same level as the flat surface 112a on which the protrusion support 512 linearly reciprocates.

The bypass hole 710 may be formed below the dust passage hole 113a. In addition, the bypass hole 710 may be formed to have a cross-sectional area smaller than that of the dust passage hole 113a.

With this configuration, when the dust collecting motor 200 generates a suction force while the dust passage hole 113a is closed, a strong suction force concentrated on a small cross-sectional area can be applied to the bypass hole 710 and effectively the residual dust can be removed.

In addition, with this configuration, when the discharge cover 2620 of the dust container 2600 is opened, the residual dust that has fallen and accumulated in the vicinity of the push protrusion 511 inside the cleaner station 1 is affected by the suction force of the dust collection motor 200 . may be sucked into the suction pipe 700 through the bypass hole 710 by the That is, if the path sucked into the suction pipe 700 through the dust container 2600 and the dust passage hole 113a is referred to as the main suction path, the residual dust separated from the dust container 2600 is near the push protrusion 511 (second coupling). A path through which the suction pipe 700 is sucked from the portion 112 through the bypass hole 710 may be referred to as a bypass suction path. The cleaner station 1 according to the embodiment of the present invention can remove dust, which is at risk of being deposited in the space near the push protrusion, through the bypass suction path inside the cleaner station, so that the inside of the cleaner station is not contaminated. It has the effect of reducing the risk and enabling hygienic management of the vacuum cleaner station.

Hereinafter, driving of the dust collecting motor 200 for removing residual dust through the bypass suction path will be described.

After the vacuum cleaner 2 is coupled to the coupling unit 110 and the door unit 600 opens the door 610 , the cover opening unit 500 opens the discharge cover 2620 so that the inside of the dustbin body 2610 and When the suction pipe 700 communicates with each other, the dust collecting motor 200 may be driven for the first time t1 . At this time, the dust-containing air passes through the main suction path and the bypass suction path to flow into the inner space S1 of the suction pipe 700 , and the dust bag 310 coupled to the lower end of the suction pipe 700 . dust may be collected.

When the dust collecting motor 200 stops driving after the first time t1 has elapsed, the door unit 600 may close the door 610 . When the door arm 620 pushes the door 610 in the direction to close the door 610 , the discharge cover 2620 may also move together with the door 610 in the direction to close the dust container 2600 . Accordingly, the discharge cover 2620 is coupled to the dust container body 2610 again, and the door 610 also closes the dust passage hole 113a.

After the door 610 is closed by the door unit 600 and the dust container 2600 is still coupled to the coupling unit 110 , the dust collecting motor 200 is re-driven for a second time t2 to increase the suction power. can cause Here, since the main suction path is closed, the air containing dust flows into the internal space S1 of the suction pipe 700 through only the bypass suction path. At this time, if the dust collecting motor 200 generates the same suction force, the suction force of the dust collecting motor 200 is larger than when the dust collecting motor 200 was driven in the state in which the door 610 was opened earlier toward the bypass suction path. can be focused

The concentration of the suction force of the dust collecting motor 200 on the bypass suction path means that the suction force acting on the residual dust increases. That is, the dust collecting motor 200 is configured to re-drive in a state in which the discharge cover 2620 and the door 610 are closed, thereby increasing the removal efficiency of residual dust.

In addition, when dust is sucked in by the dust collection motor 200 in a state in which the discharge cover 2620 and the door 610 are open, to the inside of the door 610 (on the opposite side of the side facing the discharge cover 2620). Also, dust can fly and stick, and the dust attached in this way can also be removed by configuring the dust collecting motor 200 to re-drive in the closed state of the door 610 .

Meanwhile, the first time t1 and the second time t2 may be preset in a controller (not shown) of the cleaner station 1 . In this case, the first time t1 for sucking more dust may be set to be longer than or equal to the second time t2 for sucking the remaining dust. The control unit may be accommodated in the housing 100 and may be provided to control driving, stopping, and suction force of the dust collecting motor 200 .

7 is a view looking down at the coupling part 110 from the top, and FIG. 8 is a cross-sectional view of a state in which the cleaner 2 is coupled to the coupling part 110 .

7 and 8, when the direction in which the protrusion support 512 linearly reciprocates is referred to as a first direction and a direction perpendicular to the first direction is referred to as a second direction, the The size D1 in the second direction may be smaller than the size D2 in the second direction of the flat surface 112a. In other words, from each end of the protrusion support 512 arranged in the second direction to the vertical wall 112b of the second coupling portion 112 may be spaced apart by a predetermined distance.

Foreign substances that have flowed into the second coupling part 112 of the cleaner station 1 show a random form of deposition, and most of them can be removed by the bypass hole 710 formed in the suction pipe 700 . However, when the size D1 in the second direction of the protrusion support 512 and the size D2 in the second direction of the flat surface 112a of the second coupling part 112 are approximately the same, that is, the protrusion support 512. When each end disposed in the second direction of the second coupling portion 112 is in contact with the vertical wall 112b or is configured to be disposed too close, there is a possibility that the deposited foreign material cannot escape into the bypass hole 710 this will get bigger

At this time, in particular, when hard and small foreign substances such as sand grains are deposited in a small gap between the end of the protrusion support 512 and the vertical wall 112b, resistance to linear reciprocation may occur, and the protrusion support 512 may cause foreign substances. It can make a rattling noise when rubbing against them. To solve this problem, the cleaner station 1 according to the embodiment of the present invention may be configured to be spaced apart by a predetermined distance between the end of the protrusion support 512 and the vertical wall 112b. Here, when the discharge cover 2620 is opened by the predetermined distance, it falls by gravity and flows out into the gap between the dust container body 2610 and the coupling part 110 to flow into the second coupling part 112 . It may be selected in consideration of the size of a possible foreign material. (See FIG. 8)

Through such a configuration, it is possible to solve the problems described above (eg, foreign matter deposition, resistance to linear reciprocating motion, noise generation, etc.).

Meanwhile, referring again to FIG. 7 , the movement axis L1 of the linear reciprocating movement direction of the protrusion support 512 may be disposed at the center of the second direction of the flat surface 112a. In other words, the distance from the left end of the protrusion support 512 to the near vertical wall 112b may be the same as the distance from the right end of the protrusion support 512 to the near vertical wall 112b. That is, the second coupling part 112 and the protrusion support 512 may have a symmetrical structure about the movement axis L1 of the protrusion support 512 . Through this configuration, the left and right separation distances between the protrusion support 512 and the vertical wall 112b about the movement axis L1 of the protrusion support 512 can be set to the same minimum distance, and the vacuum cleaner station There is an advantage that the interior space design of (1) is possible.

Hereinafter, the structure of the coupling lever 2630 of the cleaner 2 will be described in detail.

9 is a perspective view of the coupling lever 2630 of the cleaner 2, FIG. 10 is a perspective view of the coupling lever 2630 of FIG. 9 viewed from another direction, and FIG. 11 is a side view of the coupling lever 2630 of FIG. , FIG. 12 is a perspective view illustrating the relationship between the direction in which the lever inclined portion 2632 of the coupling lever 2630 is formed and the moving direction A of the push protrusion 511 .

9 to 12 , the coupling lever 2630 may include a lever body 2631 , a lever inclined portion 2632 , a lever side wall 2633 , a lever pressing portion 2634 , and a hook pressing portion 2635 . can

The lever body 2631 may constitute a part of the outer shape of the coupling lever 2630 . The lever body 2631 may be formed to extend along the length direction of the dust container body 2610 . At this time, the lever body 2631 may be bent by a predetermined length from both ends in a direction perpendicular to the direction in which the extension is formed in a direction toward the center of the dust container body 2610 to form an inner inner space of the coupling lever 2630 . In addition, the lever inclined portion 2632 may be connected to one end in the direction in which the lever body 2631 is extended.

The lever inclined portion 2632 may be connected to the lever body 2631 at one end from which the lever body 2631 is extended and formed to extend from the lever body 2631 .

In this case, the lever inclined portion 2632 may be provided with a dust discharge groove 2632a in which the lever inclined portion 2632 is recessed. Since the dust discharge groove 2632a is provided in the coupling lever 2630 , the residual dust flowing into the coupling lever 2630 can pass through the dust discharge groove 2632a by the suction operation of the dust collecting motor 200 and the suction pipe It may be introduced into 700 and removed.

The lever inclined portion 2632 may be inclined toward the center of the dust container body 2610 based on a state in which the coupling lever 2630 is coupled to the dust container body 2610 . In other words, the lever inclined portion 2632 may be formed extending from the lever body 2631 and inclined upward by a predetermined angle θ with respect to the moving direction A of the coupling lever 2630 . The lever inclined part 2632 may be disposed at an angle with respect to the door 610 when the cleaner 2 is coupled to the coupling part 110 . In other words, the lever inclined portion 2632 may be disposed to face the bypass hole 710 when the cleaner 2 is coupled to the coupling portion 110 . With this configuration, the dust discharge groove 2632a through which the residual dust should be escaped is not blocked by the door 610, and the residual dust can be smoothly removed through the dust discharge groove 2632a to the bypass hole 710. (refer to FIGS. 11 and 12)

The lever side wall 2633 is coupled to the lever body 2631 and the lever pressing part 2632 . One or more sidewall support ribs 2637 disposed toward the inside of the coupling lever 2630 may be coupled to each of the lever sidewalls 2633 .

The lever pressing part 2634 may be coupled to the other end of the lever body 2631 . In this case, the other end of the lever body 2631 may mean a direction opposite to the direction in which the lever inclined part 2632 is disposed. The lever pressing part 2634 may be formed to extend from the other end of the lever body 2631 in a direction perpendicular to the direction in which the lever body 2631 is extended. The lever pressing unit 2634 is a configuration in which an external force is applied by the user, and when an external force is applied to the lever pressing unit 2634 , the coupling lever 2630 moves in the longitudinal direction of the dust container 2600 to close the discharge cover 2620 . will be open

A lever hole 2634a formed to pass through the lever pressing part 2634 may be provided in the lever pressing part 2634 . The lever hole 2634a may be provided in the form of a long hole penetrating long in the direction in which the lever sidewall 2633 is disposed. In addition, the lever hole 2634a and the dust discharge groove 2632a may be disposed to face each other.

When the dust collecting motor 200 generates a suction force by the lever hole 2634a and the dust discharge groove 2632a arranged to face each other in this way, the dust discharge groove from the outside of the coupling lever 2630 through the lever hole 2634a 2632a), an air flow communicating to the bypass hole 710 may be formed, and since the air flow is not blocked by the lever pressing unit 2634 during the suction operation of the dust collecting motor 200, the suction effect of the residual dust will be further improved. will be able

The hook pressing part 2635 may be coupled to the lever pressing part 2634 . One side of the lever pressing part 2634 may be coupled to the lever body 2631 , and the other side of the lever pressing part 2634 may be coupled to the hook pressing part 2635 . In this case, the hook pressing part 2635 may be formed to extend in the same direction as the lever body 2631 . The hook pressing unit 2635 may press the coupling hook 2660 of the discharge cover 2620 to cause elastic deformation in the coupling hook 2660 . In other words, when an external force is applied to the lever pressing unit 2634 by the user, the hook pressing unit 2635 may press the coupling hook 2660 and the discharge cover 2620 may be opened. (See FIG. 12 )

13 is a schematic diagram of a suction path of residual dust through the dust discharge groove 2632a and the bypass hole 710 of the coupling lever 2630 .

12 and 13 , the residual dust that has flowed into the second coupling part 112 during the process of opening the discharge cover 2620 or the process of dust being sucked into the cleaner station 1 is the second coupling part ( It may be sucked from the 112 to the suction pipe 700 through the bypass hole 710 . In addition, in the process in which the discharge cover 2620 is opened or the dust is sucked into the cleaner station 1 , it flows into the inside of the coupling lever 2630 (the space between the coupling lever 2630 and the dust container body 2610 ). Residual dust may be sucked into the suction pipe 700 from the dust discharge groove 2632a through the bypass hole 710 .

Next, a method for removing residual dust using the cleaner system 1000 according to an embodiment of the present invention will be described with reference to FIG. 14 .

14 is a flowchart of a method for removing residual dust using the cleaner system 1000 according to an embodiment of the present invention.

First, when it is confirmed whether the cleaner 2 is coupled to the coupling unit 110 ( S100 ), in the door opening step, the door 610 provided in the cleaner station 1 is opened to communicate the outside and the inside of the cleaner station 1 . (S200) In this case, the opening of the door 610 may be performed by the door unit 600 of the cleaner station 1 described above.

On the other hand, a coupling sensor (not shown) may be disposed on the coupling part 110 to check whether the cleaner 2 is coupled to the coupling part 110 . The coupled sensor may be a contact sensor, such as a micro switch, or a non-contact sensor, such as an infrared sensor.

Next, in the step of opening the discharge cover 2620 , the discharge cover 2620 for opening and closing the dust container 2600 is opened ( S300 ). At this time, the opening of the discharge cover 2620 is the cover of the cleaner station 1 described above. It may be performed by the opening unit 500 .

When both the door 610 and the discharge cover 2620 are opened and the suction pipe 700 communicates with the inside of the dust container body 2610, it goes to the dust collection stage and the dust collection motor 200 is driven to the inside of the cleaner station 1 Dust is sucked in. (S400) The dust collecting motor 200 may be driven for a first predetermined time t1. In this case, the air containing dust may flow to the suction pipe 700 through the main suction path and the bypass suction path, and dust may be collected in the dust bag 310 .

When the dust collecting motor 200 stops driving after the first time t1 has elapsed (S500), the door unit 600 may close the door 610 together with the discharge cover 2620 in the door closing step. (S600) When the door arm 620 of the door unit 600 pushes the door 610 in the direction to close the door 610, the discharge cover 2620 also moves in the direction to close the dust container 2600. The discharge cover 2620 is coupled to the dust container body 2610 again, and the door 610 also closes the dust passage hole 113a.

Meanwhile, after the door closing step, a residual dust removal step of removing residual dust existing around the dust container 2600 is performed (S700).

In this case, in the step of removing the residual dust, the dust collecting motor 200 is re-driven for a predetermined time while the cleaner 2 is coupled to the cleaner station 1 , so that the residual dust is transferred to the inside of the cleaner station 1 . It is an inhalation process. More specifically, after the door 610 is closed by the door unit 600 , in a state in which the dust container 2600 is coupled to the coupling unit 110 , the dust collection motor 200 is re-driven for a second time t2 . This can generate suction power. At this time, since the main suction path is closed, the air containing dust passes only through the bypass suction path and flows to the suction pipe 700 while the dust collecting motor 200 is re-driven. Accordingly, when the dust collecting motor 200 generates the same suction force, the suction force may be more concentrated in the bypass suction path. That is, since the dust collecting motor 200 is configured to re-drive in a state in which the discharge cover 2620 and the door 610 are closed, the suction force provided to the residual dust increases, thereby increasing the removal efficiency of the residual dust.

On the other hand, the bypass suction path may be a path in which the residual dust that has flowed into the second coupling part 112 is sucked into the suction pipe 700 through the bypass hole 710 , or to the inside of the coupling lever 2630 . It may also be a path through which the flowed residual dust is sucked into the suction pipe 700 through the dust discharge groove 2632a and the bypass hole 710 .

In addition, the first time t1 and the second time t2 may be a predetermined time preset in the controller (not shown) of the cleaner station 1, and the first time ( t1) may be set to be longer than or equal to the second time t2 for inhaling the residual dust. The control unit may be accommodated in the housing 100 and may control driving, stopping, and suction force of the dust collecting motor 200 .

Finally, when the second time t2 has elapsed, the dust collecting motor 200 is stopped ( S800 ) and all operations of the cleaner station 1 are terminated.

As described above, according to the present invention, residual dust accumulated in the vicinity of the push protrusion inside the cleaner station can be effectively sucked through the bypass hole provided to penetrate the outside and the inside of the suction pipe.

In addition, according to the present invention, residual dust accumulated inside the coupling lever outside the dust container of the cleaner can be effectively removed through the dust discharge groove formed in the coupling lever of the cleaner.

In addition, according to the present invention, the suction power for sucking the residual dust is transferred to the bypass hole and the above through the residual dust removal step of re-driving the dust collecting motor for a predetermined time after the suction of the dust inside the dust bin is finished and the discharge cover is closed. Since it can be concentrated into the dust outlet groove, residual dust can be removed more effectively.

In the foregoing, specific embodiments of the present invention have been described and illustrated, but the present invention is not limited to the described embodiments, and those of ordinary skill in the art may make various changes to other specific embodiments without departing from the spirit and scope of the present invention. It will be appreciated that modifications and variations are possible. Accordingly, the scope of the present invention should not be defined by the described embodiments, but should be defined by the technical idea described in the claims.
