Description

Technology Field

[0001] The present invention relates to an ironing system, and more specifically, to an ironing system comprising an ironing board and a main body that rotatably supports the ironing board. Background Technology

[0002] Clothing made of specific materials, such as cotton or linen, develops significant wrinkles after washing or daily wear. To allow for repeated wear, these garments are ironed.

[0003] The most common method of ironing involves placing the garment on a blanket or ironing board on the floor and applying pressure to the garment while holding the iron. However, this method causes significant inconvenience as it forces the user to sit on the floor or crouch. Additionally, since the iron operates by receiving power, there was a limitation in that ironing had to be performed near a wall with an electrical outlet installed.

[0004] Recently, to address these issues, an ironing system has emerged that raises the ironing board for placing clothes to waist level, allowing the user to perform continuous ironing without straining their body.

[0005] Korean Patent Publication No. 2021-0004816 (hereinafter referred to as the "prior art") discloses an "ironing system," wherein the ironing system comprises an ironing board, a support member, and a grounding member.

[0006] The ironing board is equipped with a pressure surface capable of applying pressure to clothing. The ironing board is provided with a length greater than its width. Therefore, the user can place long clothing on the pressure surface and iron it.

[0007] The support member is provided beneath the ironing board to support it. The support member is provided with a height greater than its thickness or width. Therefore, the ironing board is set above an adult's waist height, allowing the user to perform ironing while standing. The grounding member is provided beneath the support member to support the load of the support member.

[0008] According to the aforementioned prior art, the supporting surface of the support member is provided with a cross-sectional area smaller than the pressing surface of the ironing board. Therefore, since the length of the ironing board is greater than the width or thickness of the supporting surface, if the load of clothing and / or the iron, or an external force from a user acts on the ironing board, a strong rotational moment is generated in the ironing system, which may cause the ironing system to overturn.

[0009] The ironing board includes straight sections extending from both sides and inclined sections that become narrower in thickness as they extend from the straight sections. The straight sections form the sides along the longitudinal direction of the ironing board, while the inclined sections form the free ends of the ironing board. Due to the inclined sections, the surface area of ​​the ironing board narrows toward one end of the pressure surface. The user can insert a portion of clothing into the free end of the inclined section and iron it. Therefore, the inclined sections must have sufficient length along the longitudinal direction of the ironing board.

[0010] The above ironing system further includes a connecting part. The connecting part is rotatably coupled to the upper part of the support part and the lower part of the ironing board, respectively. As the radius of the connecting part at the lower part of the ironing board becomes shorter, the support reaction force of the connecting part against the force applied to the ironing board increases, and the ironing board and the connecting part may be easily damaged. Also, as the cross-sectional area of ​​the ironing board becomes smaller, the ironing board may be easily damaged. Therefore, to prevent damage to the ironing board and the connecting part, the connecting part and the inclined part must each have a sufficient length along the longitudinal direction of the ironing board.

[0011] According to the aforementioned prior art, the rear surface of the support member is opened and closed by a cover. The user can open the cover and pull out and use an iron and a water container housed in an internal storage space. The iron is stored horizontally on the upper side of the storage space, and the water container is provided below the iron.

[0012] As described above, since the setting height of the ironing board is determined by the height of the support member, it is necessary to optimize the arrangement of the iron and water tank housed inside the cover. Additionally, it is necessary to optimize the arrangement and ratio of the part where the connecting member is rotatably joined, the electrical room, the housing space, and the steam supply unit. The problem to be solved

[0013] The present invention aims to solve the above-mentioned problems of an ironing system comprising an ironing board and a main body that rotatably supports the ironing board.

[0014] Specifically, the purpose is to provide an ironing system capable of ensuring overturning stability against forces acting on the pressure surface of the ironing board by optimizing the length ratio of the ironing board to the main body.

[0015] In addition, the present invention aims to provide an ironing system that can prevent damage to the ironing board and the connecting part caused by the force applied to the ironing board by optimizing the arrangement of the connecting part and the inclined part based on the longitudinal direction of the ironing board.

[0016] In addition, the present invention aims to provide an ironing system that optimizes the internal structure of the support member so that the ironing board can be used at a comfortable height, while allowing the cover to be opened to conveniently store and retrieve the iron, steam generator, and water tank.

[0054] According to the ironing system according to an embodiment of the present invention, when a pressure force (P) is applied in the direction of gravity to a first point on the pressure surface while the first central axis is in an upright state (usage state), the point reaction force acting on the ironing board can be summarized as shown in [Equation 1] below.

[0055]

[0056] When a pressure force is applied in the direction of gravity at the first point of the pressure surface while the first central axis is in an upright state (usage state), the force acting on the connection part and the main body can satisfy the following [Equation 2].

[0057]

[0058] When designing the ironing system, a constant can be substituted into L3 of [Equation 1]. Additionally, an estimated value of the pressure that may be applied in the direction of gravity to the first point of the pressure surface due to user error can be substituted into [Equation 1]. When designing the ironing system, a constant can be substituted into W of [Equation 2]. Therefore, [Equation 2] can be organized into an equation with L1 and L2 as variables. If the force acting on the connecting part and the main body satisfies [Equation 2], the ironing system may not be overturned by the pressure acting in the direction of gravity at the first point of the pressure surface.

[0059] According to an ironing system according to an embodiment of the present invention, the overturning stability of the ironing system can be improved as L1 increases relative to L3. The ironing board, connecting part, and main body can satisfy [Equation 4] below by considering the factor of safety under the condition that [Equation 2] is satisfied. Therefore, by having a length of at least 15% of L3, the overturning stability of the ironing system can be secured.

[0060]

[0061] According to an ironing system according to an embodiment of the present invention, when the lower surface of the ironing board and the upper surface of the main body are separated while the first central axis is in an upright state (usage state) (see FIG. 13), the third point may be located at the end of the upper surface of the connecting part. At this time, the ironing board, the connecting part, and the main body may satisfy [Equation 5] below by considering the factor of safety under the condition that [Equation 2] is satisfied. Therefore, by having a length of at least 50% of L4, the overturning stability of the ironing system can be secured.

[0062]

[0063] According to an ironing system according to an embodiment of the present invention, the ironing board, the connecting part, and the main body can satisfy [Equation 6] below by considering the factor of safety under the condition that [Equation 2] is satisfied. Therefore, by having a length of L2 that is four times or less of L1, the overturning stability of the ironing system can be secured.

[0064]

[0065] According to an ironing system according to an embodiment of the present invention, the ironing board, the connecting part, and the main body can satisfy [Equation 7] below by considering the factor of safety under the condition that [Equation 2] is satisfied. Therefore, by having a length of 50% or more of L2, the overturning stability of the ironing system can be secured.

[0066]

[0067] According to an ironing system according to an embodiment of the present invention, the support member may include a water supply member, a storage member, and a hinge member. The water supply member may be provided on a grounding member. The storage member may be provided on a water supply member. The hinge member may be provided between the upper surface of the main body and the storage member. The iron, the steam generator, and the water tank may each be stored in the storage member in an elongated vertical direction. The vertical length of the storage member may be 50% to 60% of the vertical length of the support member. The vertical length of the hinge member may be 10% to 15% of the vertical length of the support member. Accordingly, in the operating state of the ironing system, the pressure surface is positioned at a height advantageous for ironing, while the area of ​​the support member in the plan view can be reduced.

[0068] According to an ironing system according to an embodiment of the present invention, the inner surface of the storage unit may include a first mounting surface on which a steam generator is mounted and a second mounting surface on which an iron is mounted. The first mounting surface and the second mounting surface may form a step difference from each other in the direction in which the steam generator and the iron enter and exit the storage room (Y-axis direction; hereinafter referred to as the 'entry direction'). When the cover closes the storage room, the second mounting surface may be spaced further from the cover than the first mounting surface. As the first mounting surface and the second mounting surface form a step difference from each other in the entry direction, the handle of the steam generator and the handle of the iron may be positioned at the same location in the Y-axis direction. Accordingly, the user can easily and quickly store and retrieve the steam generator and the iron from the storage room.

[0069] According to an ironing system according to an embodiment of the present invention, the ironing board may include a straight section and an inclined section. The ironing board may reduce the area of ​​the pressure surface due to the inclined section, and the area of ​​the pressure surface may become narrower as it approaches one end in the longitudinal direction of the ironing board. Accordingly, a user can insert a part of clothing into the free end of the ironing board through the inclined section and iron the clothing. Based on the longitudinal direction of the ironing board, the straight section and the inclined section may be connected to each other at the same point as the end of the upper surface of the connecting plate. Therefore, the inclined section can secure a sufficient length while preventing damage to the ironing board and the connecting section.

[0070] According to an ironing system according to an embodiment of the present invention, the ironing board may be provided with a length greater than its width. The support member may be provided with a height greater than its width to ensure the height of the ironing board during use of the ironing system. The width of the ironing board and the width of the support member may be the same. The rear surface of the ironing board (the surface opposite to the pressure surface) may have its longitudinal direction parallel to the height direction of the seating surface. Therefore, the storage area of ​​the ironing system can be reduced. In addition, the planar area of ​​the ironing board, which has a high center of gravity in the ironing system, is reduced, thereby preventing the support member from tipping over.

The central axis of the horizontal axis (hereinafter referred to as the 'second central axis (402)') may be perpendicular to the first central axis (401) and parallel to the horizontal direction.

[0104] The connecting shaft (410) can be rotatably coupled inside the hinge portion (260) so that the first central shaft (401) can stand or lie down. The hinge portion (260) may include a first boundary surface and a second boundary surface. The first boundary surface and the second boundary surface may form the boundaries on both sides of the path where the connecting shaft (410) rotates 90 degrees around the second central shaft (402).

[0105] The connecting axis (410) can contact the first boundary surface while the first central axis (401) is parallel to the Y-axis. The connecting axis (410) can contact the second boundary surface while the first central axis (401) is parallel to the Z-axis. Thus, the user can rotate the ironing board (100) by 90 degrees around the second central axis (402).

[0106] A locking device that blocks rotation of the horizontal axis when the first central axis (401) is standing or lying down may be provided inside the hinge part (260). A locking button that operates the locking device may be provided on the side of the support part (200).

[0107] FIG. 5 is a perspective view of an ironing system (1) according to an embodiment of the present invention, viewed from the front upper side, and is a drawing showing the usage state of the ironing system (1).

[0108] The ironing board (100) may include a straight section (111) and an inclined section (112).

[0109] The straight section (111) can form both sides of the ironing board (100). The straight section (111) can be parallel to the longitudinal direction of the ironing board (100).

[0110] The inclined portions (112) can be connected to the straight portions (111) respectively. The inclined portions (112) can become closer to each other as they extend along the length of the ironing board (100). The inclined portions (112) can form the free end of the ironing board (100).

[0111] The ironing board (100) can reduce the area of ​​the pressure surface (110) due to the inclined portion (112), and the area of ​​the pressure surface (110) can become narrower as it approaches one end in the longitudinal direction of the ironing board (100). Therefore, the user can insert a part of the clothing into the free end of the ironing board (100) through the inclined portion (112) and iron the clothing.

[0112] The ironing board (100) may include a seating portion (130). The seating portion (130) may be provided between the pressure surface (110) and the end of the ironing board (100) with respect to the longitudinal direction of the ironing board (100).

[0113] In the operating state of the ironing system (1), the seating portion (130) can form a concave space downward. Therefore, in the operating state of the ironing system (1), the user can stably place items such as an iron (700) on the seating portion (130) and use them.

[0114] The ironing board (100) may include a display unit (140). The display unit (140) may be provided next to the mounting unit (130). The display unit (140) may be exposed upward during the use of the ironing system (1). Therefore, the user can easily and conveniently use the display unit (140) during the use of the ironing system (1).

[0115] A gyro sensor may be installed inside the ironing board (100). The control unit can automatically recognize the current state of the ironing system (1) by receiving a signal from the gyro sensor. The control unit can output different information to the display unit (140) depending on the current state of the ironing system (1).

[0116] FIG. 6 is a perspective view of an ironing system (1) according to an embodiment of the present invention, viewed from the front upper side, showing the storage state, first state, usage state, and second state of the ironing system (1). FIG. 6 illustrates the storage state, first state, usage state, and second state of the ironing system (1) in a clockwise order starting from the top left.

[0117] The storage state of the ironing system (1) may mean that the first central axis (401) is parallel to the Y-axis and the longitudinal direction of the ironing board (100) is parallel to the Z-axis (see FIG. 3).

[0118] The user can switch the ironing system (1) to a storage state by rotating the ironing board (100) 90 degrees so that the longitudinal direction of the ironing board (100) is parallel to the Z-axis in the second state of the ironing system (1). Alternatively, the user can switch the ironing system (1) to a storage state by rotating the ironing board (100) 90 degrees so that the first central axis (401) lies flat in the first state of the ironing system (1).

[0119] A handle (150) may be provided on the edge of the ironing board (100) behind the pressure surface (110). The user may rotate the ironing board (100) by holding the handle (150). Alternatively, the user may rotate the ironing board (100) by pushing or pulling one side of the ironing board (100).

[0120] In the storage state of the ironing system (1), the ironing board (100), the connecting part (400), and the supporting part (200) can be positioned on the grounding part (300). Therefore, in the storage state, the ironing system (1) can form the smallest area in the plan view compared to other states. Thus, the movement and storage of the ironing system (1) can be easy in the storage state.

[0121] The user can move the ironing system (1) by pushing or pulling one side of the ironing board (100) or the main body (10).

[0122] The first state of the ironing system (1) may mean a state in which the first central axis (401) is parallel to the Z-axis and the longitudinal direction of the ironing board (100) is parallel to the Y-axis (see FIG. 3).

[0123] The user can switch the ironing system (1) to a first state by rotating the ironing board (100) 90 degrees so that the first central axis (401) stands upright in the storage state of the ironing system (1). Alternatively, the user can switch the ironing system (1) to a first state by rotating the ironing board (100) 90 degrees so that the longitudinal direction of the ironing board (100) is parallel to the X-axis in the usage state of the ironing system (1).

[0124] In the first state of the ironing system (1), the pressure surface (110) can form a surface parallel to a level surface. Therefore, the user can place clothing, etc. on the pressure surface (110) in the first state. Depending on the case, the user can iron the clothing placed on the pressure surface (110) with an iron in the first state of the ironing system (1).

[0125] The usage state of the ironing system (1) may mean that the first central axis (401) is parallel to the Z-axis and the longitudinal direction of the ironing board (100) is parallel to the X-axis (see FIG. 3).

[0126] The user can switch the ironing system (1) to a usage state by rotating the ironing board (100) 90 degrees in the first state of the ironing system (1) so that the longitudinal direction of the ironing board (100) is parallel to the X-axis. Alternatively, the user can switch the ironing system (1) to a usage state by rotating the ironing board (100) 90 degrees in the second state of the ironing system (1) so that the first central axis (401) is upright.

[0127] In the state of use of the ironing system (1), the pressure surface (110) can form a surface parallel to the level surface. Therefore, in the state of use of the ironing system (1), the user can press the clothing placed on the pressure surface (110) with the iron and iron it.

[0128] And in the usage state of the ironing system (1), the longitudinal direction of the ironing board (100) may be parallel to the X-axis. The lower surface of the grounding part (300) may be longer in the X-axis direction than in the Y-axis direction.

[0129] Therefore, when a pressure force is applied in the direction of gravity to the end of the pressure surface (110) in each of the first state and the usage state of the ironing system (1), the ironing system (1) may have higher overturning stability in the usage state than in the first state. In the usage state of the ironing system (1), the user can sufficiently press the clothing placed on the pressure surface (110) with the iron and iron it.

[0130] The second state of the ironing system (1) may mean a state in which the first central axis (401) is parallel to the Y-axis and the longitudinal direction of the ironing board (100) is parallel to the X-axis (see FIG. 3).

[0131] The user can switch the ironing system (1) to a second state by rotating the ironing board (100) 90 degrees so that the first central axis (401) lies flat while the ironing system (1) is in use. Alternatively, the user can switch the ironing system (1) to a second state by rotating the ironing board (100) 90 degrees so that the longitudinal direction of the ironing board (100) is parallel to the Z-axis while the ironing system (1) is in storage.

[0132] FIG. 7 is a front view of an ironing system (1) according to an embodiment of the present invention.

[0133] The ironing board (100) may be provided with a length (H1) that is longer than its width (D1). The support member (200) may be provided with a height (H2) that is longer than its width (D2) to ensure the height of the ironing board (100) in use of the ironing system (1). The width of the ironing board (100) and the width of the support member (200) may be the same.

[0134] The back surface of the ironing board (100) (opposite side of the pressure surface (110)) may have its length direction parallel to the height direction of the seating surface (212). Thus, the storage area of ​​the ironing system (1) can be reduced.

[0135] Additionally, the planar surface area of ​​the ironing board (100), which has a high center of gravity in the ironing system (1), is reduced to prevent the support member (200) from tipping over. In the storage state of the ironing system (1), the back surface of the ironing board (100) may be placed on the seating surface (212) or spaced apart by a small gap (see FIG. 3).

[0136] FIG. 8 is a perspective view of an ironing system (1) according to an embodiment of the present invention, viewed from the front upper side, and is a drawing showing the interior of the storage unit (240) in the storage state of the ironing system (1).

[0137] FIG. 9 is a front view of an ironing system (1) according to an embodiment of the present invention, showing the interior of a storage unit (240) in a storage state of the ironing system (1).

[0138] Each of the iron (700), steam generator (800), and water tank (230) can be stored vertically in the storage section (240). Accordingly, the vertical length of the storage section (240) can be determined by the lengths of the iron (700), steam generator (800), and water tank (230).

[0139] The iron (700), steam generator (800), and water tank (230) can be spaced apart from each other in the X-axis direction while stored in the storage unit (240).

[0140] As the iron (700), steam generator (800), and water tank (230) are each stored vertically in the storage section (240), the vertical length of the storage section (240) may be 50% to 60% of the vertical length of the support section (200). The vertical length of the hinge section (260) may be 10% to 15% of the vertical length of the support section (200).

[0141] As each of the iron (700), steam generator (800), and water tank (230) is stored vertically in the storage section (240), the pressure surface (110) is positioned at a height advantageous for ironing while the area of ​​the support section (200) in the plan view can be reduced.

[0142] The height at which the aforementioned pressure surface (110) is advantageous for ironing may mean the average waist height of an adult or a height greater than that. Therefore, when a user irons while using the ironing system (1), they can perform ironing while standing upright or while standing without excessively crouching their upper body.

[0143] The inner surface of the storage section (240) may include a first mounting surface (240a) on which a steam generator (800) is mounted, and a second mounting surface (240b) on which an iron (700) is mounted. The first mounting surface (240a) and the second mounting surface (240b) may form a step difference from each other in the direction in which the steam generator (800) and the iron (700) enter and exit the storage room (Y-axis direction; hereinafter 'entry / exit direction').

[0144] With the cover (250) closing the storage room, the second mounting surface (240b) may be further separated from the cover (250) than the first mounting surface (240a).

[0145] As the first mounting surface (240a) and the second mounting surface (240b) form a step difference with respect to each other in the entry / exit direction, the handle (150) of the steam generator (800) and the handle (150) of the iron (700) can be positioned at the same location in the Y-axis direction. Therefore, the user can easily and quickly store and retrieve the steam generator (800) and the iron (700) from the storage room.

[0146] Based on the longitudinal direction of the ironing board (100), the straight section (111) and the inclined section (112) can be connected to each other at the same point (EP) as the end of the upper surface of the connecting plate (420).

[0147] As the radius of the connecting plate (420) becomes shorter around the first central axis (401), the support reaction force of the connecting part (400) increases, and the ironing board (100) and the connecting part (400) can be easily damaged. Also, as the cross-sectional area of ​​the ironing board (100) becomes smaller, the ironing board (100) can be easily damaged.

[0148] Based on the longitudinal direction of the ironing board (100), the straight section (111) and the inclined section (112) are connected to each other at the same point (EP) as the end of the upper surface of the connecting plate (420), thereby preventing damage to the ironing board (100) and the connecting section (400) while ensuring that the inclined section (112) has sufficient length.

[0149] FIG. 10 is a front view of an ironing system (1) according to an embodiment of the present invention, showing the pressure (P) and reaction force acting on the ironing board (100) in the usage state of the ironing system (1).

[0150] FIG. 11 is a front view of an ironing system (1) according to an embodiment of the present invention, showing the force and reaction force acting on the connecting part (400) and the main body (10) in the state of use of the ironing system (1).

[0151] When the first central axis (401) is in an upright state (used state) and a pressure force (P) is applied in the direction of gravity to the first point (S1) of the pressure surface (110) (see FIG. 10), the point reaction force acting on the ironing board (100) can be summarized as [Equation 1] below.

[0152]

[0153] Here, R a It can be located at the second point (S2) as a point reaction force of the connection part (400) to the pressure (P). The second point (S2) can be located on the first central axis (401).

[0154] R b It can be located at a third point (S3) as a point reaction force of the main body (10) or the connecting part (400) against the pressure (P). The third point (S3) can be located between the first point (S1) and the second point (S2) with respect to the first central axis (401).

[0155] FIG. 12 is a partial front view of an ironing system (1) according to an embodiment of the present invention, illustrating contact between the lower surface of the ironing board (100) and the upper surface of the main body (10) in the state of use of the ironing system (1).

[0156] When the lower surface of the ironing board (100) and the upper surface of the main body (10) come into contact with the first central axis (401) in an upright state (used state) (see FIG. 12), the third point (S3) may be located at the end of the upper surface of the main body (10).

[0157] FIG. 13 is a partial front view of an ironing system (1) according to an embodiment of the present invention, illustrating the separation between the lower surface of the ironing board (100) and the upper surface of the main body (10) in the state of use of the ironing system (1).

[0158] When the lower surface of the ironing board (100) and the upper surface of the main body (10) are separated while the first central axis (401) is in an upright state (used state) (see FIG. 13), the third point (S3) may be located at the end of the upper surface of the connecting part (400). The end of the upper surface of the connecting part (400) may refer to the end of the upper surface of the connecting plate (420).

[0159] L1 may be a horizontal distance between the second point (S2) and the third point (S3). L3 may be a horizontal distance between the first point (S1) and the second point (S2). The first point (S1) may be located at the end of the pressure surface (110) based on the longitudinal direction of the ironing board (100).

[0160] When the first central axis (401) is in an erected state (used state) and a pressure force (P) is applied in the direction of gravity to the first point (S1) of the pressure surface (110), the force acting on the connecting part (400) and the main body (10) (see FIG. 11) can satisfy the following [Equation 2].

[0161]

[0162] Here, L2 may be a horizontal distance between the second point (S2) and the fourth point (S4). The fourth point (S4) may be a point of contact between the lower surface of the main body (10) and the ground when the ironing system (1) is overturned by pressure (P).

[0163] When the ironing system (1) is overturned by the pressure (P), the ironing system (1) can rotate around the fourth point (S4). R c This may be a point reaction force acting on the fourth point (S4) when the ironing system (1) is overturned by the pressure (P). The fourth point (S4) may be located at the end of the lower surface of the main body (10).

[0164] W can be located at the fifth point (S5) as a load of the ironing system (1). The fifth point (S5) can be located on the first central axis (401).

[0165] When designing the ironing system (1), a constant can be substituted into L3 of [Equation 1]. Also, an estimated value of the pressure (P) that can be applied in the direction of gravity to the first point (S1) of the pressure surface (110) due to a user error can be substituted into [Equation 1].

[0166] For example, if you substitute 1.0m for L3 and 20kg for P, R a and R b can be a function with L1 as a variable, as shown in [Equation 3] below. That is, R a and R b can be determined by L1.

[0167]

[0168] When designing the ironing system (1), a constant can be substituted for W in [Equation 2]. For example, 45 kg can be substituted for W. R a and R b Since [Equation 2] is a function with L1 as a variable, [Equation 2] can be rearranged into an expression with L1 and L2 as variables.

[0169] If the force acting on the connecting part (400) and the main body (10) (see FIG. 11) satisfies [Equation 2], the ironing system (1) may not be overturned by the pressure (P) acting in the direction of gravity on the first point (S1) of the pressure surface (110).

[0170] As L1 increases relative to L3, the overturning stability of the ironing system (1) can be improved. The ironing board (100), the connecting part (400), and the main body (10) can satisfy [Equation 4] below by considering the safety factor under the condition that [Equation 2] is satisfied. That is, by having a length of at least 15% of L3, the overturning stability of the ironing system (1) can be secured.

[0171]

[0172] When the lower surface of the ironing board (100) and the upper surface of the main body (10) are separated while the first central axis (401) is in an upright state (usage state) (see FIG. 13), the third point (S3) may be located at the end of the upper surface of the connecting part (400). At this time, the ironing board (100), the connecting part (400), and the main body (10) may satisfy the following [Equation 5] by considering a safety factor under the condition that [Equation 2] is satisfied.

[0173]

[0174] Here, L4 may be a horizontal distance between the second point (S2) and the upper end of the main body (10). That is, by having a length of at least 50% of L4, the inversion stability of the ironing system (1) can be secured.

[0175] And the ironing board (100), connecting part (400), and main body (10) can satisfy the following [Equation 6] by considering the safety factor under the condition that [Equation 2] is satisfied.

[0176]

[0177] That is, by having a length of less than 4 times that of L1, the overturning stability of the ironing system (1) can be secured.

[0178] And the ironing board (100), connecting part (400), and main body (10) can satisfy the following [Equation 7] by considering the safety factor under the condition that [Equation 2] is satisfied.

[0179]

[0180] That is, by having a length of more than 50% of L2, the overturning stability of the ironing system (1) can be secured.
