Description

Air purifier

Technical Field

The present invention relates to an air purifier, and more particularly, to a humidifying air purifier as a detachable sink, which can prevent the sink from being erroneously mounted by moving the sink to a normal mounting position even in the process of mounting a water tub in the sink mounting process in the case of being erroneously mounted at a position separated from the normal mounting position when the sink is mounted.

Background

An air cleaner is a device that forcibly sucks polluted outside air into the interior, purifies the air, and then discharges the purified filtered air to the outside. Recently, in order to improve the usability of air purifiers, air purifiers have been developed which have functions in addition to the air purification function. As these examples, a humidifying air purifier with an additional humidifying function may be cited.

The humidifying air purifier requires management such as cleaning of a water tank for performing a humidifying function. For this purpose, a common sink is provided in a detachable form.

When humidification air purifier provides the structure of detachable basin, the user dismantles the in-process of back reinstallation with the basin in the use, the possibility of how much dislocation of normal mounted position in the follow casing can appear. Thus, when the water tank is placed in a staggered manner, the fastening of the water tank and the water tub cannot be normally formed, and the humidifying function cannot be performed. Such an infeasibility of the humidifying function is easily solved by a user's righting the position of the water tank, however, when the user regards it as a malfunction, it may cause unnecessary repair request and reduce the image of the product, and thus improvement is required.

On the other hand, the conventional humidifying air purifier generally has a structure in which a sink, a water tub, and the like are disassembled from a side direction of the air purifier. For example, Korean laid-open patent No. 10-2019-0029819 of WINIA, Inc. has a structure in which a water tank 300 is detached through a side surface of a body 100 of an air cleaner. Also, korean laid-open patent No. 10-2018-0073361 of hauwei corporation, "humidifying air purifier" discloses a structure in which the water tank 130 is detachable toward one side of the frame 120. When the indoor air purifier is arranged for use, due to other furniture, indoor design, wallpaper and the like, the space for detaching the water tank is difficult to ensure on the side face of the indoor air purifier. Therefore, according to this structure, there is sometimes an inconvenience that the air cleaner needs to be moved from the installation position in order to detach the sink 130.

The air cleaner 1 according to an embodiment of the present invention is provided with a humidifying part 40 at an upper part of the filter part 30. Accordingly, the air cleaner 1 can function as a humidifier in addition to air cleaning. More specifically, the outside air a1 flows into the air inlet 121 formed in the lower front portion of the casing 10 of the air cleaner 1, is filtered by the filter unit 30, and is discharged as filtered air a2 through the first discharge port 111 formed in the upper portion of the casing 10 without passing through the humidifying unit 40 or is discharged as filtered humidified air A3 through the second discharge port 122 formed in the upper front portion of the casing 10 after being filtered, according to the flow path provided in the air cleaner 1.

Referring to fig. 1 to 3, an air cleaner 1 according to an embodiment of the present invention includes a housing 10, an air blowing part 20, a filter part 30, a humidification part 40, a guide part 50, and a flow path setting part 60.

Hereinafter, each configuration of the air cleaner 1 according to an embodiment of the present invention will be described in detail.

The housing 10 forms the outer shape of the air cleaner 1. The casing 10 provides a space in which the air blowing unit 20, the filter unit 30, the humidification unit 40, the guide unit 50, and the flow path installation unit 60 can be installed. The casing 10 has an air inlet 121 through which the outside air a1 flows, a first outlet 111 through which the filtered air a2 is discharged, a second outlet 122 through which the filtered and humidified air A3 is discharged, a bucket inlet 112 through which a bucket 43 described later is inserted, and the like formed on the outer surface thereof.

The housing 10 may include a housing body 11 and a front cover 12. The casing body 11 is formed in a front surface-opened state to provide a space for installing the air blowing unit 20, the filter unit 30, the humidifying unit 40, the guide unit 50, and the flow path installation unit 60. The front cover 12 is provided to cover the front surface of the housing body 11.

A first discharge port 111 and a water tub insertion port 112 are formed on the upper surface of the housing body 11. Thus, when the water tub insertion opening 112 is provided on the upper surface of the housing 10, the water tub 43 of the humidifying part 40 is inserted into the lower side direction through the water tub insertion opening 112, so that the water tub 41 of the humidifying part 40 can be installed, and conversely, when separated from the water tub 41, the water tub can be taken out in the upper side direction of the air cleaner 1.

An air inlet 121 for allowing the outside air a1 to flow therein is formed in a lower portion of the front cover 12, and a second discharge port 122 is formed in an upper portion of the front cover 12. In the embodiment of the present invention, the first discharge port 111 is formed in a grid pattern, and the air inlet 121 and the second discharge port 122 are formed by a plurality of through holes formed through the front cover 12.

On the other hand, the front cover 12 is formed so that both sides thereof extend rearward (toward the housing body 11 in the drawing), and includes a recessed portion 123 recessed forward at an upper portion thereof. The recess 123 prevents the discharged filtered humidified air A3 from receiving excessive flow path resistance from the second discharge opening 122 to generate noise, and provides a path through which part of the filtered humidified air A3 can be discharged, thereby reducing noise during use of the air cleaner 1.

In an embodiment of the present invention, the housing 10 is formed in a quadrangular barrel shape in a state where the housing body 11 is coupled with the front cover 12. Of course, the shape of the housing 10 is not limited thereto, and may have other shapes. The positions and shapes of the air inlet 121, the first discharge port 111, and the second discharge port 122 may be changed as needed. For example, the air inlet 121 may be formed on a plurality of surfaces among the front, rear, left, and right surfaces of the casing 10 so that air can be sucked in a plurality of directions, and the positions, shapes, and the like of the first discharge port 111 and the second discharge port 122 may be changed as needed.

The blower 20 supplies a blowing force to flow outside air a1 into the casing 10. The blowing unit 20 provides a flow force to discharge the air filtered inside the casing 10 to the outside. More specifically, the blowing unit 20 supplies the blowing force so that the outside air a1 flowing into the air inlet 121 passes through the filter member 31 of the filter unit 30 to be filtered air a2, and then flows into the first discharge port 111 or the second discharge port 122. Specifically, the air blowing part 20 may include a motor, an impeller, and the like.

The lower air blowing unit 20 in the casing 10 is provided behind the filter unit 30. Of course, the position and form of the blowing unit 20 are not limited to this, and may be changed according to design requirements.

The filter unit 30 is disposed at a lower side of the inside of the case 10, filters the outside air a1 and makes filtered air a 2. The filter portion 30 includes a filter member 31 that passes and filters the outside air a 1. Also, a pre-filter 32 may be provided between the front of the filter member 31 and the rear of the front cover 12, the pre-filter 32 having and being provided with a plurality of inflow holes 32a through which the outside air a1 passes.

The filter part 31 may be formed of an ULPA (Ultra-Low Efficiency Air) filter, a HEPA (High Efficiency molecular Air) filter, a dust removing filter such as a medium-sized filter, or a functional filter that filters bacteria or microorganisms included in the inhaled Air, which collects dust and filters Ultra-fine dust included in the Air of 0.1 to 0.3 μm or fine dust of 0.3 μm or more.

In one aspect, in one embodiment of the present invention, the prefilter 32 is formed of a four-corner lattice shape. This is merely exemplary, and the pre-filter 32 is not limited thereto, and may be formed in various forms according to dust collection efficiency.

The humidifying section 40 humidifies the filtered air a2 passing through the filter section 30. In the air cleaner 1 according to the embodiment of the present invention, the humidifying part 40 is disposed at an upper side of the filter part 30. When a flow path is formed for humidification after filtration, the filtered air a2 filtered by the filter member 31 of the filter unit 30 flows to the humidification unit 40, and the humidification unit 40 supplies moisture to the filtered air a2 to form filtered humidified air A3.

Referring to fig. 2 to 5, the humidifying part 40 of the air purifier 1 according to the embodiment of the present invention includes a water tank 41, a humidifying part 42, and a water tub 43.

The water tank 41 includes mounting

portions

411 and 412 each having an open container shape at an upper portion thereof. The mounting parts 411,412 may include a first mounting part 411 to mount the humidifying part 42 and a second mounting part 412 to mount a water tub 43 for supplying water to be supplied to the humidifying part 42 to the water tub 41. The first and second mounting

portions

411 and 412 may be adjacently disposed. Specifically, a first mounting portion 411 is formed at one side portion of the water tank 41, and a second mounting portion 412 adjacent to the first mounting portion 411 may be formed at the other side portion of the water tank 41.

The water tank 41 is detachably formed from an installation position inside the housing 10 to the outside of the housing 10. In more detail, in the embodiment of the present invention, the water tank 41 is detachably formed toward the front of the case 10. Accordingly, according to the case of the embodiment of the present invention, even if there are other objects on the side of the air purifier 1 such that the space is narrow, the sink 41 can be detached after only the front cover 12 is detached at the use position of the air purifier 1, and thus, the user can conveniently perform the detachment of the sink 41.

On the other hand, the water tank 41 has a water receiving portion 413 for storing water overflowing from the water tank 41. When the water tank 41 is removed or when an external force is applied during use of the air cleaner 1, the water receiving part 413 prevents water inside the water tank 41 from overflowing. The water receiving part 413 may be provided in front of the water tank 41. Specifically, the water receiving unit 413 may be connected to and disposed in front of the water tank 41 so that the front side wall 41a of the mounting

portions

411 and 412 of the water tank 41 becomes the rear side wall of the water receiving unit 413.

The front side wall 413a of the water receiving part 413 is formed to have the same height as the front side wall 41a of the mounting parts 411,412 of the water tank 41. In the embodiment of the present invention, the height of the front side wall 41a of the mounting portions 411,412 is lower at the center than at the both side portions, and accordingly, the height of the front side wall 413a of the water receiving portion 413 is lower at the center than at the both side portions. These structures may maximize water holding capacity while minimizing flow path impedance applied to filtered humidified air a3 passing through humidification components 42.

On the other hand, as best shown in fig. 2, in the embodiment of the present invention, the groove 113 is formed at a certain position on the inner surface of one side wall and the other side wall of the case 10 forming the mounting position, and the protrusion 414 may be formed on the outer surface of one side wall and the other side wall of the water tank 41, the protrusion 414 being formed to be inserted into the groove 113 from the mounting position.

By these grooves 113 and projections 414, the user can easily grasp whether the water tank 41 is accurately positioned at the set mounting position when inserting the water tank 41. Of course, the recess 113 and the projection 414 may be formed reversely. In other words, the protrusions may be formed at predetermined positions on the inner surfaces of one side wall and the other side wall of the housing 10, and the grooves may be formed on the outer surfaces of one side wall and the other side wall of the water tank 41.

The humidifying member 42 is attached to the first attachment portion 411, receives water from the water tank 41, and supplies moisture to the filtered air a 2. The humidifying unit 42 performs humidification in a vaporizing manner (air blowing manner) using the water supplied to the first mounting portion 411 of the water tank 41. In the embodiment of the present invention, the humidifying member 42 is attached to the front surface of the casing 10 in parallel to the rear surface of the second discharge port 122.

The humidifying member 42 is provided at the rear end of the blower 20 on the air flow path. When the humidifying member 42 is positioned at the front end of the air blowing unit 20 on the air flow path, the air with high humidity passing through the humidifying member 42 passes through the air blowing unit 20, and the air blowing unit 20 is broken. When the flow path is set to the humidification mode by the flow path setting unit 60 described later, the outside air a1 flowing in by the operation of the blower unit 20 passes through the filter member 31 of the filter unit 30 to become filtered air a2, then passes through the humidification member 42, and is discharged as filtered humidified air A3 through the second discharge port 122.

On the other hand, since the filter unit 30 is provided at the front end of the blowing unit 20 and the humidifying part 42 is provided at the rear end of the blowing unit 20 on the air flow path, when only the air purifying function is performed according to the flow path arrangement of the flow path arrangement unit 180, the flow of the air filtered from the filter unit 30 to the humidifying part 42 is restricted, and thus the air purifying efficiency can be improved. Accordingly, even if the impeller provided in the blower 20 is driven at a relatively low RPM and low power, a sufficient discharge rate can be secured and noise can be reduced.

The humidifying member 42 may be made of a material or a shape having excellent hygroscopicity so as to sufficiently absorb the water stored in the water tank 41. For example, the humidifying member 42 may have a structure immersed in the water contained in the water tank 41. The humidifying unit 42 is not limited to the above-described configuration, and various known types of vaporizing humidifying structures such as a rotary disk type may be used if vaporizing humidifying is possible.

The water tub 43 is mounted on the second mounting part 412 to supply water to the water tub 41. The water supplied from the water tub 43 is supplied to the first mounting portion 411 of the water tank 41 and is immersed in the humidifying part 42. In the embodiment of the present invention, the water tub 43 includes a water tub body 431 containing water for humidification and a valve member 432 that can open and close discharge of the water contained in the water tub body 431.

In order to facilitate the water to be contained inside the water tub body 431, the water tub 43 has a structure detachable from the air cleaner 1. Also, the valve member 432 may be installed by a cap structure bolted to an inlet (inlet) of the water tub body 431.

The valve member 432 includes an opening/closing portion 432a elastically supported by an elastic tool (e.g., a spring), and may have a mechanical valve structure that is maintained in a closed state in a state where the opening/closing portion 432a is not pressurized and in an open state in a state where the opening/closing portion 432a is pressurized. The opening by the pressing of the opening/closing portion 432a and the closing by the release of the pressing state will be described in detail later.

The guide portion 50 is formed to protrude upward around the second mounting portion 412 of the water tank 41 where the water tub 43 is mounted. When the water tub 43 enters around the second mounting portion 412 in a state where the water tub 41 is disposed inside the housing 10 out of a certain range from the mounting position, the guide portion 50 is pressurized by the water tub 43. When the guide portion 50 is pressurized by the water tub 43, the water tank 41 moves to the installation position direction by the pressurizing force supplied to the guide portion 50.

The guide portion 50 may be formed behind the second mounting portion 412 with reference to the front-rear direction of the inserted air cleaner 1 in the water tank 41. Accordingly, in the case where the water tank 41 is erroneously disposed inside the housing 10 out of a certain range forward from the normal mounting position, when the water tub 43 enters around the second mounting portion 412, the water tank 41 is pressurized by the water tub 43 contacting the guide portion 50, and thus can be moved to the rear accurate position.

The guide portion 50 may include any one or more of the first guide member 51 and the second guide member 52.

The first guide member 51 may be formed as a wall body extending forward from the rear side wall 41b of the mounting

portions

411, 412. Specifically, the first guide member 51 may be formed as a wall body extending forward from the rear side wall 41b of the second mounting portion 412 of the water tank 41.

The first guide member 51 may have an inclined portion 51a inclined upward from the front end portion toward the rear side on the upper surface. As such, when the first guide member 51 includes the inclined portion 51a inclined upward from the front end portion toward the rear side, the valve member 432 portion of the water tub 43 descends along the inclined portion 51a in the process of the water tub 43 entering the second mounting portion 412 of the water tub 41, and the moving force toward the rear side can be effectively provided to the water tub 41.

The second guide member 52 is disposed around the second mounting portion 412 and may be formed of a flow path switch that opens a flow path between the water tub 43 and the water tub 41 in a pressed state and supplies water in the water tub 43 to the water tub 41, and closes between the water tub 43 and the water tub 41 in an unpressed state. When the water tub 43 enters around the second mounting part 412 in a state where the water tub 41 is disposed inside the housing 10 out of the mounting position by a certain range, the second guide member 52 has a head 521 pressurized by the water tub at an upper end. At this time, the head 521 of the second guide member 52 may be disposed rearward of the second mounting portion 412 where the water tub 43 is mounted.

When the water tank 41 is disposed inside the housing 10 in a state where it is deviated from the mounting position to the front of the housing 10 by a certain extent, the water tub 43 enters around the second mounting part 412, and the head 521 of the second guide member 52 is pressurized by the water tub 43 and moved to the rear by the pressurized water tank 41.

The head 521 of the second guide member 52 may have an inclined portion 521a inclined downward from the inner side to the second mounting portion 412 and from the outer side. As such, when the head 521 of the second guide member 52 has the inclined portion 521a inclined downward from the inside to the outside, the valve member 432 of the water tub 43 partially descends along the inclined portion 521a in the process of the water tub 43 entering the second mounting portion 412 of the water tub 41, and the moving force to the rear side can be effectively provided to the water tub 41.

In the embodiment of the present invention, the head portions 521 of the first guide member 51 and the second guide member 52 are respectively disposed behind the second mounting portion 412 and may be disposed in parallel. As described above, when the guide part 50 includes both the first guide member 51 and the second guide member 52, the transmission of the pressure from the water tub 43 is more reliably and stably transmitted to the water tub 41 when the water tub 43 is entered in a state where the water tub 41 is erroneously mounted, and as a result, the movement of the water tub 41 to the mounting position can be more reliably ensured.

Fig. 6 is a view illustrating a state where a sink is disposed apart from an installation position in an air cleaner according to an embodiment of the present invention, and fig. 7 is a view illustrating that a first guide member and a second guide member are pressurized to move the sink to the installation position in a process where the water tub of fig. 6 is installed in the sink.

Referring to fig. 6, when the water tank 41 is inserted from the front of the air cleaner 10, the water tank cannot be pushed sufficiently to the correct position, and the first mounting portion 411 and the second mounting portion 412 are in a misplaced state, and are spaced forward from the rear correct position reference line P1 of the first mounting portion 411 and the correct position reference line P2 of the second mounting portion 412 by a predetermined distance, respectively.

In this state, when the water tub 41 is not moved to the originally set installation position to form the installation of the water tub 43, the water tub 43 cannot be installed at an accurate position to form a normal humidifying function.

As shown in fig. 7, according to the case of the embodiment of the present invention, when the water tub 43 enters in the lower direction through the water tub insertion opening 112 formed at the upper surface of the housing 10, the guide part 50, i.e., the first guide part 51 and the second guide part 52, are in contact with the valve part 432 of the water tub 43. The first guide member 51 and the second guide member 52 of the guide portion 50 are pressurized by a load of the water tub 43 or a force pressed by the user, and thereby transmit the moving force F to the rear side to the water tub 41. As a result, the water tub 41 is moved backward and set at a correct position, and the water tub 43 can be normally fastened to the second mounting part 412. Therefore, even if the water tank 41 is fastened by mistake due to carelessness of the user, the setting of the exact position of the water tank 41 and the normal combination of the water tub 43 can be formed when the water tub 43 is installed, and thus the humidifying function can be performed normally.

As described above, the second guide member 52 is provided around the second mounting portion 412 and is formed of a flow path switch that opens a flow path between the water tub 43 and the water tub 41 in a pressed state, supplies water in the water tub 43 to the water tub 41, and closes the flow path between the water tub 43 and the water tub 41 in an unpressed state. The configuration and function of the flow path switch of the second guide member 52 will be described with reference to fig. 8 and 9.

Referring to fig. 8 and 9, the second guide member 52 is exposed around the second mounting portion 412, and includes a head portion 521 formed by pressurizing a flow path installation portion 60, which will be described later, in the humidification mode on one side, and a pressing portion 522 provided for pressing an opening/closing portion 432a of the valve member 432 when the head portion 521 is pressed on the other side. The guide portion 50 has a main body portion 523 connecting between the head portion 521 and the pressing portion 522, and has a rotation shaft portion 524, the rotation shaft portion 524 being formed between the main body portion 523 and the head portion 521, and rotationally driving the second guide member 52 so that the pressing portion 522 presses the switch portion 432a when the head portion 521 is pressed.

That is, when the second guide member 52 presses the head portion 521 to perform the function as the flow path switch, the rotating shaft portion 524 is moved as a jumper plate to raise the pressing portion 522 to press and open the switch portion 432a, and when the pressing of the head portion 521 is released, the pressing portion 522 is lowered by the self weight of the second guide member 52 or the elastic force of an elastic member (not shown) to close the switch portion 432 a.

The flow path setting section 60 is rotatably provided in an air flow path inside the housing 10, and adjusts the flow of air to the

discharge ports

111, 122. As shown in fig. 3, the flow path setting unit 60 is provided with a flow path for allowing the air filtered by the filter unit 30 to be discharged through at least one of the first discharge port 111 and the second discharge port 122.

Referring to fig. 10, the flow path setting part 60 includes a main body 61, a rotation shaft 62, and a pressurizing part 63, the main body 61 is formed to cross the air flow path so as to open and close at least a part of the air flow path, the rotation shaft 62 forms a rotation center of the main body 61, the pressurizing part 63 rotates around the rotation shaft 62 according to the main body 61, and pressurizes the head part 521 of the guide part 50.

The flow path setting section 60 may be rotated by a driving section M formed of a motor or the like. Therefore, the control unit C controls the driving unit M to rotate the flow path setting unit 60.

Referring to fig. 9, the casing 10 has an inner wall 114 defining an air flow path therein, and the second guide member 52 is positioned outside the inner wall 114. At this time, the main body 61 of the flow path installation portion 60 is positioned on the air flow path inside the inner wall 114, and the pressurizing portion 63 of the flow path installation portion 60 is provided outside the air flow path through the inner wall 114, and can pressurize the head portion 521 of the second guide member 52.

Hereinafter, operations in the purification mode, the humidification mode, and the drying mode of the air purifier 1 according to the embodiment of the present invention will be described with reference to fig. 11 to 13.

First, in the purge mode, as shown in fig. 11, the flow path setting portion 60 is placed in the vertical direction so that the filtered air a2 flows in the direction of the first discharge port 111 formed in the upper portion of the casing 10. Thus, when the main body 61 of the flow path installation unit 60 is placed in the vertical direction, the filtered air a2 blown from the blowing unit 20 is induced to be discharged through the first discharge port 111 formed in the upper portion of the casing 10 due to the flow path resistance of the humidifying member 42.

At this time, since the pressing portion 63 of the flow path installation portion 60 is in a state of being spaced apart from the head portion 521 of the second guide member 52, the pressing portion 522 of the second guide member 52 does not press the open/close portion 432a of the valve member 432. Thereby, the opening and closing part 432a maintains the closed state, and the water supply from the water tub 43 to the water tank 41 is not formed.

Next, as shown in fig. 12, in the humidification mode, the flow path setting portion 60 is provided obliquely so as to block the flow of air toward the first discharge port 111 side in order to guide the filtered air a2 rising from the lower portion of the casing 10 toward the humidification portion 40 side.

In this case, since the upper end of the main body 61 of the flow path setting section 60 is adjacent to the partition wall W partitioning the inside of the air flow path of the housing 10 and the lower end is adjacent to the side opposite to the partition wall W, the air flowing while blocking the rise of the air flows into the humidifying section 40 through the through holes WH formed in the partition wall W. Accordingly, the air blown by the blowing unit 20 becomes the filtered humidified air a3 humidified by the humidifying member 42 of the humidifying unit 40, and can be discharged to the outside of the casing 10 through the second discharge port 122.

At this time, since the pressing portion 63 of the flow path setting portion 60 comes into contact with the head portion 521 of the second guide member 52 to press the head portion 521, the head portion 521 of the second guide member 52 moves in the downward direction with reference to the rotation shaft portion 524, and the pressing portion 522 moves in the upward direction with reference to the rotation shaft portion 524. Accordingly, the pressing portion 522 of the second guide member 52 presses the open/close portion 432a of the valve member 432 from the upper side, and the open/close portion 432a moves upward. Accordingly, the opening and closing part 432a is opened, thereby forming water supply from the water tub 43 to the water tank 41.

On the one hand, as shown in fig. 13, the flow path setting portion 60 may have a third position (drying mode) between the purification mode position and the humidification mode position. In this case, the drying of the humidifying part 42 and/or the water tank 41 may be formed.

Specifically, since the upper end of the flow path setting portion 60 is slightly spaced apart from the partition wall W partitioning the air flow path and the lower end is slightly spaced apart from the opposite side of the partition wall W, part of the air flows upward and flows into the humidifying portion 40 through the through-holes WH formed in the partition wall W. Accordingly, the air passing through the humidifying part 42 may perform the drying of the humidifying part 42. The humidifying member 42 may have a structure capable of absorbing moisture of the water stored in the water tank 41, and in this case, the water stored in the water tank 41 may be dried by drying the humidifying member 42.

When the flow path setting part 60 is rotated from the humidification mode position to the drying mode, the contact between the pressurizing part 63 of the flow path setting part 60 and the head part 521 of the second guide member 52 is released, and therefore, the opening and closing part 432a provided in the valve member 432 is closed, and the water supply from the water tub 43 to the water tank 41 is blocked.

At this time, in order to improve the drying efficiency, the position of the flow path setting part 60 in the drying mode may be set to sufficiently secure the amount of air blown to the humidifying part 40. For example, the position of the flow path setting part 60 in the drying mode may be formed to a degree slightly rotated from the humidifying mode position so that the contact between the pressurizing part 63 and the head part 521 of the second guide member 52 may be released and the opening and closing part 432a may be closed.

Although one embodiment of the present invention has been described, the concept of the present invention is not limited to the embodiments presented in the present specification, and those skilled in the art who understand the concept of the present invention should understand that other embodiments can be easily proposed by addition, modification, deletion, addition, etc. of the constituent elements within the scope of the same concept, and this is included in the scope of the concept of the present invention.
