Description

Garment processing equipment

[0001] The present invention relates to a garment treatment device. More specifically, the present invention relates to a garment treatment device that performs a refreshing process by supplying at least one of air and steam to the garment, thereby performing at least one of deodorizing, wrinkle removal, and sterilizing the garment.

[0002] Garment treatment equipment refers to devices developed for washing, drying, and removing wrinkles from clothing, both at home and in laundries. These devices include washing machines, dryers, washer / dryers with both washing and drying functions, garment care machines, which refresh clothing, and steamers, which remove wrinkles from clothing.

[0003] Recently, a clothing treatment device has appeared that can keep clothes comfortable and clean without having to soak them in water and wash them with detergent.

[0004] In this conventional clothing treatment device, a clothing treatment device has appeared that performs a refreshing process of supplying either high-temperature air or steam to the clothing to deodorize the clothing, dry the clothing, and remove wrinkles from the clothing.

[0005] The garment treatment device capable of performing the above-mentioned refreshing process may be equipped to hold the garment while supplying hot air or steam to the garment to remove fine dust or foreign substances attached to the garment. See Korean Patent Publication No. 10-1285890.

[0006] Figure 1 illustrates a structure for holding clothes in a conventional clothing treatment device.

[0007] A moving hanger (M) of a conventional clothing treatment device includes a support bar (2) arranged in a receiving space where the clothing is placed, a hanging part (3) extending downward from the support bar (2) so that the clothing can be placed, and a driving part (5) capable of moving the support bar (2).

[0008] The above driving unit (5) may include a motor (51) that is fixed to the upper portion of the support bar (2) and rotates a rotation shaft (53), and may include an eccentric shaft (55) that is coupled to the rotation shaft (53) and rotates along a trajectory larger than the rotation radius of the rotation shaft (53).

[0009] The above support bar (2) may be provided with a reciprocating guide unit (4) that receives power by accommodating the eccentric shaft at the center. The eccentric shaft (55) may be provided to move along the rotation of the rotation shaft (53) while being coupled to the reciprocating guide unit (4) and to reciprocate the reciprocating guide unit (4) left and right.

[0010] The above eccentric shaft (55) can be provided to rotate by being coupled to the end of a connecting shaft (52) coupled to the end of a rotating shaft (53).

[0011] Figure 2 illustrates a structure in which the support bar moves left and right.

[0012] The above reciprocating guide unit (4) may be formed in the thickness direction of the support bar (2) and may be provided with a slit (41) that accommodates the eccentric shaft (55).

[0013] Figure 2 illustrates a structure in which the support bar moves left and right.

[0014] The above reciprocating guide unit (4) may be formed in the thickness direction of the support bar (2) and may be provided with a slit (41) that accommodates the eccentric shaft (55).

[0015] Referring to Fig. 2(a), the eccentric shaft (55) may be inserted into the slit (41) and rotated along an arc path with a radius of a distance R away from the rotation axis (52).

[0016] The above support bar (2) may be provided so that it can be moved only left and right in the clothing treatment device and cannot be moved forward or backward.

[0017] Referring to Fig. 2(b), when the eccentric shaft (55) rotates 90 degrees to the right, the slit (41) can move R to the right together with the eccentric shaft (55) due to the eccentric shaft (55) moving R to the right. As a result, the support bar (2) moves to the right.

[0018] In this way, when the eccentric shaft (55) rotates 180 degrees to the left, the slit (41) will move to the left, and the support bar (2) will also move to the left.

[0019] When the above rotation shaft (53) rotates once, the support bar (2) can move back and forth left and right once, and when the above rotation shaft (53) rotates continuously, the support bar (2) moves back and forth left and right several times.

[0020] As a result, the clothing hung on the hanging member (3) extended from the support bar (2) is moved left and right, so that foreign substances or dust can be separated.

[0021] However, since the support bar (2) of this conventional clothing treatment device moves back and forth left and right, there was a problem in that the entire clothing treatment device vibrated strongly due to the sudden application of inertial force whenever the support bar (2) changed its direction of movement.

[0022] In particular, the more clothes are placed on the hanger (3) or the heavier the clothes are, the greater the vibration becomes, which poses a problem in that the stability of the clothes handling device cannot be guaranteed.

[0023] In addition, the existing clothing treatment device had a problem in that the greater the vibration, the greater the noise generated, so the noise was emitted every time the clothing treatment device was operated, and the use of the clothing treatment device was restricted at night, etc.

[0024] Figure 3 illustrates a state in which the drive unit output of a conventional clothing treatment device is lost.

[0025] In addition, the conventional clothing treatment device had a problem in that even if the driving unit (5) could apply sufficient output, the maximum output of the driving unit (5) could not be utilized because the vibration generated by the reciprocating movement of the support bar (2) exceeded the reference value.

[0026] In addition, there was a problem that the moving hanger of the left-right reciprocating type, such as the conventional clothing treatment device, did not receive all of the rotational power of the driving force of the driving unit (3).

[0027] Specifically, the slit (41) of the support bar (2) of the above moving hanger can transmit the force that rotates the eccentric shaft (55) to the left or right to the clothing, but cannot transmit the force that rotates the eccentric shaft (55) to the rear or front to the clothing at all, resulting in the loss of the force.

[0028] Specifically, when the eccentric shaft (55) is positioned at positions I and III, the slit (41) can directly receive the force moving to the right and left.

[0029] However, when moving from the above I position to the II position and when moving from the above III position to the IV position, the force transmitted to the eccentric shaft (55) to move the slit (41) left and right is drastically reduced.

[0030] This is because the force that moves the slit (41) by the eccentric shaft (55) corresponds only to the cosine value of the rotational direction of the eccentric shaft (55), and therefore, when the eccentric shaft (55) is at positions of 90 degrees and 270 degrees with respect to the center of rotation, the power transmitted from the eccentric shaft (55) to the slit (41) corresponds to 0.

[0031] In other words, the driving unit (5) continuously transmits power to the eccentric shaft (55), but the eccentric shaft (55) can only transmit part of the power to the slit (41), and cannot even transmit all of the power at a specific point.

[0032] As a result, in the conventional clothing treatment device, the power of the driving unit (5) is mostly lost without being transmitted to the clothing. Therefore, the conventional clothing treatment device has a problem in that even though the driving unit (3) has sufficient output to stimulate the clothing, sufficient exciting power is not transmitted to the clothing, or the driving unit (3) must be driven with excessive output to transmit sufficient exciting power to the clothing.

[0033] As a result, the conventional clothing treatment device had a fundamental problem in that it did not have a good performance in separating foreign substances or dust attached to the clothing because sufficient driving force was not transmitted to the clothing from the driving unit (3).

[0034] In addition, the conventional clothing treatment device had a problem in that the rotational force generated from the driving unit (3) could not be directly transmitted to the support bar (2) because the support bar (2) was arranged in the width direction and the hanging part (3) was also fixed to the support bar (2).

[0035] To solve this problem, a clothing treatment device capable of shaking the hanger (3) on which the clothing is placed in a reciprocating rotational motion rather than a linear reciprocating motion has been developed. (See Chinese Patent Publication No. 111759148)

[0036] Figure 4 illustrates the rotation structure of the hanging part of the conventional known technology.

[0037] The above-mentioned hook part (3) is rotatably mounted on the upper part of the above-mentioned support bar (2), and a link part (5) that is secured on the upper part of the hook part (3) and can move back and forth left and right is provided.

[0038] The above reciprocating guide part (4) can be connected to the outer surface of the above hanging part (3) through a fastening member (6).

[0039] The portion where the above fastening member (6) is connected to the hook portion (3) can be positioned apart from the center of rotation of the hook portion (3).

[0040] The above reciprocating guide part (4) can be provided as a bar-shaped link, and when the reciprocating guide part (4) moves back and forth left and right in the width direction, the fastening part (6) can move the reciprocating guide part (4) back and forth.

[0041] As a result, the above-mentioned hanging part (3) can rotate back and forth left and right, and the clothes placed on the hanging part (3) can also rotate back and forth.

[0042] However, in the above-described prior art, when the link part (5) rotates reciprocally, the reciprocating guide part (4) must move forward and backward to a certain extent according to the rotational trajectory of the hook part (3). As a result, the left-right reciprocating movement of the reciprocating guide part (4) cannot be a perfect left-right reciprocating movement.

[0043] Meanwhile, when the above-mentioned hook parts (3) are arranged in multiple pieces and spaced apart, and one of the above-mentioned reciprocating guide parts (4) is provided to reciprocate by the driving part (3), it may appear that the plurality of hook parts (3) can be rotated reciprocally.

[0044] However, in order for the plurality of hooks (3) to reciprocate, the reciprocating guide unit (4) coupled with the plurality of hooks (3) must move forward or backward to correspond to each rotational trajectory of the plurality of hooks (3). However, since one end of the reciprocating guide unit (4) is fixed to the end (51) of the driving unit (3), the reciprocating guide unit (4) cannot move forward or backward as a whole in the same manner as the rotational trajectory of the plurality of hooks (3).

[0045] That is, the reciprocating induction unit (4) moves forward or backward at a certain angle with one end connected to the driving unit (3) as the center. In other words, the reciprocating induction unit (4) is provided with an amplitude that is greater at the other end, which is further away from the driving unit (3), than at the first end.

[0046] Therefore, when the plurality of hanging parts (3) are arranged in parallel along the width direction of the support bar (2), it is theoretically impossible to rotate all of the plurality of hanging parts (3) by the reciprocating guide part (4).

[0047] Therefore, the reciprocating induction unit (4) cannot rotate multiple hook units (5) simultaneously or at the same time.

[0048] As a result, the above-mentioned prior art had a fundamental problem in that, when the above-mentioned hook parts (3) are provided in multiple numbers, the multiple hook parts (3) cannot be rotated back and forth simultaneously or at the same time.

[0049] Figure 5 illustrates a cross-section of the hanging part in a conventional clothing treatment device.

[0050] The above-mentioned hanging part is designed based on the case where there is no rotation or translational movement of the garment. Accordingly, the hanging part is designed to withstand only the load due to the gravity of the garment.

[0051] However, as described above, since the conventional clothing treatment device causes the clothing to move in translation or rotation by the moving hanger, increasing the rigidity to withstand the load is an important task for the clothing treatment device equipped with the moving hanger.

[0052] The present invention aims to provide a clothing treatment device equipped with a moving hanger capable of withstanding the load caused by gravity of clothing.

[0053] The present invention aims to provide a clothing processing device equipped with a moving hanger capable of withstanding a load caused by translational movement of clothing.

[0091] Figure 6 illustrates the appearance of the clothing treatment device (1) of the present invention.

[0092] Referring to FIG. 6(a), the garment treatment device of the present invention may include a cabinet (10) forming an exterior and a door (11) rotatably coupled to the cabinet (10).

[0093] Referring to Fig. 6(b), an inner case (20) having a storage space (21) for storing clothing may be provided inside the cabinet (10). The inner case (20) may have an opening at the front through which clothing enters and exits, and the opening may be shielded by the door (11).

[0094] The above inner case (20) may be provided with a plastic resin series, and may be provided with a reinforced plastic resin series that does not deform even when exposed to air at a temperature higher than room temperature or heated air (hereinafter, hot air) and steam or moisture.

[0095] The inner case (20) may be provided with a height greater than its width. As a result, the clothing can be accommodated in the accommodation space (21) without being folded or wrinkled.

[0096] The clothing treatment device (1) of the present invention may include a clothes hanger (900) capable of placing clothes in the receiving space (21) of the inner case (20).

[0097] The above-mentioned hanger part (900) is provided on the upper surface of the inner case (20) and can be mounted on the hanger part (700) for holding clothes. The above-mentioned hanger part (900) can be detachably mounted on the hanger part (700).

[0098] When the clothing is placed on the above-mentioned hanging part (700), the clothing can be placed in a floating state in the air inside the receiving space (21).

[0099] The garment treatment device of the present invention may further include a pressurizing part (50) that is coupled to the inner surface of the door (11) and can fix the garment.

[0100] The above-mentioned pressurizing unit (50) may include a pressurizing surface (522) arranged on the inner surface of the door (11), and a pressurizing panel (521) that is rotatably coupled to the pressurizing surface (522) and can pressurize clothing placed on the pressurizing surface (522). The pressurizing unit (50) can mainly pressurize long clothing, such as lower garments, to remove wrinkles and can also create intended creases.

[0101] The clothing treatment device of the present invention may be equipped with a machine room (30) in which various devices capable of supplying at least one of hot air or steam to the receiving space (21) or purifying or dehumidifying the external air of the cabinet (10) are installed.

[0102] The above machine room (30) may be arranged to be separated or partitioned from the inner case (20), but may be provided to communicate with the inner case (20).

[0103] The above machine room (30) can be placed at the bottom of the inner case (20). Thus, when hot air and steam with low specific gravity are supplied to the inner case (20), the hot air and steam can be naturally supplied to the clothing.

[0104] The above machine room (30) may include a circulation duct that circulates air inside the inner case (20), and a plurality of heat exchangers that are arranged on the circulation duct to cool and condense the air and heat the air.

[0105] The above machine room (30) may be equipped with a heat pump system including a compressor that is connected to the plurality of heat exchangers and can compress a refrigerant that cools or heats the air.

[0106] Meanwhile, the machine room (30) may also be equipped with a steam supply unit capable of supplying steam to the inside of the inner case (20).

[0107] The above steam supply unit may be configured to heat water to generate steam. Accordingly, clothing contained within the inner case may be exposed to hot air and steam, thereby undergoing deodorization, sterilization, and wrinkle removal.

[0108] The front of the machine room (30) may include a water tank (31) for supplying water to generate the steam, and a drain tank (32) for collecting water condensed in the circulation duct.

[0109] The water tank (31) and drain tank (32) can be detachably installed at the front of the machine room (30). Accordingly, even if the garment treatment device of the present invention is not placed near a water source or sewer, the user can detach and transport the water tank (31) and drain tank (32) whenever necessary.

[0110] The above water tank (31) and drain tank (32) can be arranged in parallel along the width direction of the machine room (30).

[0111] In addition, the machine room (30) may further include a drawer (33) for storing items necessary for managing the clothing. The drawer (33) may be provided so as to be withdrawable from the machine room (30), and may be provided with a space therein for storing items such as an iron.

[0112] A mounting plate (60) on which a separate shelf can be mounted may be provided inside the inner case (20). The mounting plate (60) may be provided to protrude at the same height on both sides of the inner case (20).

[0113] The above-mentioned mounting plate (60) may be provided with a light-emitting part that irradiates light into the interior of the inner case (20), and the light-emitting part is provided to irradiate light toward the inner surface of the inner case (20) to prevent glare.

[0114] Meanwhile, the clothing treatment device of the present invention may further include a moving hanger (100) that shakes the clothes hanger (900) to remove foreign substances and dust from clothes placed on the clothes hanger (900).

[0115] The above clothing is equipped with the moving hanger (100) to be driven when at least one of hot air and steam is supplied to the clothing, so that foreign substances attached to the clothing can be separated by the hot air or steam.

[0116] The above moving hanger (100) may be provided to move the above clothes hanger (900) back and forth.

[0117] Figure 7 illustrates the upper structure of the inner case.

[0118] The moving hanger (100) of the garment treatment device of the present invention may include a power transmission unit (400) arranged on the upper portion of the inner case (10) to swing the hanger (900).

[0119] The above power transmission unit (400) may include a hollow portion with one side open. The detailed structure thereof will be described later.

[0120] A hanging portion (700) may be provided below the power transmission unit (400) on which the clothes hanger (900) may be mounted or placed. The hanging portion may be connected to both sides of the power transmission unit, excluding the one side. A detailed structure thereof will be described later.

[0121] Accordingly, when the power transmission unit (400) moves, the hanging unit (700) moves, and the hanger (900) placed on the hanging unit (700) shakes, causing the clothes to flutter.

[0122] The power transmission unit (400) may be provided in multiple units, and the hanging unit (700) coupled to the power transmission unit (400) may also be provided in multiple units. As a result, a large number of clothes corresponding to the number of power transmission units (400) may be placed inside the inner case (20) and refreshed.

[0123] The above moving hanger (100) may further include a driving unit (200) that provides power to move the power transmission unit (400).

[0124] The above driving unit (200) may be provided so as to be exposed inside the inner case (20) if it can transmit power to the power transmission unit (400). However, since the driving unit (200) is provided so as to operate by receiving electric energy, it is preferable that exposure to steam or hot air be blocked.

[0125] Accordingly, the driving unit (200) can be placed between the upper surface of the inner case (20) and the cabinet (10) to prevent it from being exposed to the receiving space (21).

[0126] The power transmission unit (400) can receive power from the driving unit (200) by penetrating the inner case (20) and transmit it to the hanging unit (700).

[0127] The power transmission unit (400) may penetrate the upper surface of the inner case (20) and extend into the receiving space (21). The lower end of the power transmission unit (400) may be exposed to the receiving space (21), and the upper end of the power transmission unit (400) may be exposed above the inner case (20).

[0128] The inner case (200) or the support member (800) may further include a sealing member capable of sealing an area penetrated by the power transmission member (400). The sealing member may include a support bearing or the like that is coupled to a hole in the inner case (200) and the support member (800) that allows the power transmission member (400) to penetrate therethrough and rotatably support the power transmission member (400).

[0129] In this way, air and steam supplied to the inside of the inner case (200) can be prevented from leaking out above the upper surface of the inner case (200) or above the support member (800).

[0130] As a result, the driving unit (200) can be driven stably without problems such as leakage, short circuit, or overheating due to being installed above the support unit (800).

[0131] The above power transmission unit (400) may be provided in a rod shape, a tube shape, or a plate shape, etc., in which the length is longer than the thickness.

[0132] Meanwhile, the upper surface of the inner case (20) can support the load of the power transmission unit (400) and the driving unit (200). Clothes are placed and moved on the power transmission unit (400), and the load of the driving unit (200) is also relatively heavy. Therefore, in order to stably install the moving hanger (100) on the upper surface of the inner case (20), the clothing treatment device (1) of the present invention may further include a support unit (800).

[0133] The above support member (800) is placed on the upper portion of the inner case (20), and can be supported by being coupled to the cabinet (1). The above support member (800) can be made of a durable and non-deformable metal material.

[0134] The power transmission unit (400) and the driving unit (200) may be mounted on the support unit (800) and placed on the upper portion of the inner case (20). The power transmission unit (400) may extend through the support unit (800) into the receiving space (21).

[0135] Meanwhile, the driving unit (200) includes a motor that rotates the rotation shaft. The driving unit (200) may be provided to move the power transmission unit (400) using the power that rotates the rotation shaft.

[0136] However, it may be difficult to sufficiently shake the power transmission unit (400) by simply rotating the rotation axis in place.

[0137] Accordingly, the moving hanger (100) may further include a displacement generating unit (300) that is coupled to a rotating shaft that rotates by the motor and generates sufficient displacement to enable the power transmission unit (400) to move.

[0138] The displacement generating unit (300) may be connected or coupled to the driving unit (200).

[0139] For example, the displacement generating unit (300) may be provided to transmit the power of the driving unit (200) to the power transmission unit (400).

[0140] The displacement generating unit (300) may include an eccentric shaft that rotates along a trajectory larger than the diameter of the rotational axis. The eccentric shaft may be directly coupled to the rotational axis of the driving unit (200), but may be eccentrically coupled to or extended from a power shaft (240) that rotates by the rotational axis.

[0141] The displacement generating unit (300) may be configured in any manner as long as it can generate displacement that causes the power transmission unit (400) to move back and forth within a certain range. The detailed structure will be described later.

[0142] When the above driving unit (200) operates, the power generated from the rotation shaft generates displacement of the displacement generating unit (300), and the power transmission unit (400) can move according to the displacement of the displacement generating unit (300).

[0143] The displacement generating unit (300) can directly move the power transmission unit (400), but can also move the power transmission unit (400) through additional configuration.

[0144] The moving hanger (100) of the present invention can be equipped to move the power transmission unit (400) back and forth.

[0145] In addition, the moving hanger (100) of the present invention may be equipped to rotate the power transmission unit (400). Specifically, the moving hanger (100) may be equipped to rotate the power transmission unit (400) reciprocally within a certain angular range, rather than moving the power transmission unit (400) reciprocally in a straight line.

[0146] The power transmission unit (400) may be provided to reciprocate clockwise or counterclockwise from a fixed position, and clothing placed on the power transmission unit (400) may also rotate clockwise or counterclockwise. The power transmission unit (400) is provided to rotate by the moving hanger (100), but its position may be changed to the left or right, etc., and may not move.

[0147] Even if the clothing rotates due to the power transmission unit (400) inside the inner case (20), the movement of the center of gravity inside the inner case (20) can be restricted. Accordingly, even if the moving hanger (100) operates, the vibration generated inside the inner case (20) can be drastically reduced, and noise generation can also be minimized.

[0148] To this end, the moving hanger (100) may further include a reciprocating rotation unit (500) that converts continuous rotational energy generated from the driving unit (200) or the displacement generating unit (300) into a reciprocating rotational motion of the power transmission unit (400).

[0149] The reciprocating rotation part (500) may be provided to connect the displacement generating part (300) and the power transmitting part (400) to each other. The reciprocating rotation part (500) may be provided to connect the displacement generating part (300) and the power transmitting part (400) to each other above the inner case (20). The reciprocating rotation part (500) is prevented from being exposed to the receiving space (21), thereby preventing the clothing from being damaged by the reciprocating rotation part (500).

[0150] Meanwhile, the moving hanger (100) may be provided to reciprocate only one of the plurality of power transmission units (400).

[0151] However, if only one power transmission unit (400) rotates, clothing placed on the rotating power transmission unit may collide with clothing placed on another power transmission unit (400) and be damaged. In addition, there is a risk that the impact may be transmitted to the moving hanger (100), causing damage to the moving hanger (100).

[0152] Therefore, it is preferable that the moving hanger (100) be equipped to rotate all of the plurality of power transmission units (400).

[0153] The above moving hanger (100) can rotate multiple power transmission units (400) as a single unit. The moving hanger (400) can be configured to simultaneously rotate multiple power transmission units (400) at the same angle. Thus, the garment treatment device of the present invention can prevent the power transmission units (400) from colliding with each other.

[0154] The power generated in the above driving unit (200) can be directly transmitted to multiple power transmission units (400), which can be advantageous in rotating all of the power transmission units (400).

[0155] However, if the driving unit (200) is equipped to directly transmit power to each power transmission unit (400), the structure connecting the driving unit (200) and all power transmission units (400) may become complicated.

[0156] In addition, if the driving unit (200) is provided in multiple units or if the components connecting all power transmission units (400) in the driving unit (200) are provided in multiple units, excessive load may be applied to the inner case (20) or the support unit (800). In addition, the inconvenience of having to control multiple driving units (200) may also arise.

[0157] In addition, if the displacement generating unit (300) and the reciprocating rotating unit (500) are connected to transmit the power transmitted from one driving unit (200) to each of the power transmission units (400), the arrangement and structure of the displacement generating unit (300) and the reciprocating rotating unit (500) may become complicated, which may lower reliability.

[0158] Therefore, the above moving hanger (100) can be equipped so that one driving unit (200) generates power to rotate a plurality of power transmission units (400).

[0159] In addition, the moving hanger (100) may be provided so that the power generated in the driving unit (200) is preferentially transmitted to some of the power transmission units (400) or some of the reciprocating rotation units (500), and the remaining power transmission units (400) or the remaining reciprocating rotation units (500) can secondarily receive the power.

[0160] For example, the reciprocating rotating part (500) may be provided to receive power transmitted from the driving part (200) or the displacement generating part (300) and transmit it to some of the power transmission parts (400). That is, the moving hanger (100) is provided to intensively transmit the power generated from the driving part (200) to one reciprocating rotating part (500), so that the power transmission structure can be designed simply and power loss can be minimized.

[0161] The moving hanger (100) of the present invention may be provided so as to transmit power transmitted from the driving unit (200) to one reciprocating rotating unit (500), thereby rotating a specific power transmission unit (400) connected to the reciprocating rotating unit (500).

[0162] In addition, the moving hanger (100) may further include a connecting portion (600) that is provided to transmit power transmitted to a specific power transmission portion (400) to another power transmission portion (400).

[0163] For example, the connecting portion (600) may be provided to connect a plurality of power transmission portions (400) to each other. Thus, when one power transmission portion (400) rotates, the connecting portion (600) can rotate all of the plurality of power transmission portions (400).

[0164] Figure 8 illustrates how the moving hanger of the present invention operates.

[0165] Referring to Fig. 8(a), the power transmission unit (400) can rotate to the right by the reciprocating rotation unit (500) when the driving unit (200) operates. At this time, the power transmission units (400) connected to the connecting unit (600) can also rotate to the right.

[0166] Referring to Fig. 8(b), the power transmission unit (400) can rotate to the left by the reciprocating rotation unit (500) when the driving unit (200) is further operated. At this time, the power transmission units (400) connected to the connecting unit (600) can also rotate to the left.

[0167] As this process is repeated, the power transmission unit (400) can rotate left and right.

[0168] At this time, the power transmission unit (400) may be provided to rotate left and right while being fixed in a fixed position. The power transmission unit (400) may be fixed to the support unit (800) so that there is no change in position in the forward, backward, left and right directions when rotating.

[0169] The above power transmission unit (400) can be fixed so that its position does not move in the up-down direction, front-back direction, and width direction.

[0170] However, the power transmission unit (400) may be configured to rotate left and right with the vertical or height direction in which the power transmission unit extends as the rotation axis. As a result, when the driving unit (200) is driven, the hook unit (700) may rotate left and right reciprocally with the power transmission unit (400) as the axis, and there may be no positional movement.

[0171] Referring to FIG. 8(c), the clothes hanger (900) may include a ring portion (910) that is mounted on the hanger portion (700) and a mounting portion (900) that is coupled to the ring portion (910). A surface portion (950) that prevents clothing from slipping may be provided on the surface of the mounting portion (950).

[0172] The above-mentioned fixing portion (950) may be provided symmetrically left and right with the ring portion (910) as the center. The above-mentioned hanger portion (900) may be mounted on the above-mentioned hook portion (700) so that the fixing portion (950) is arranged in the front-back direction.

[0173] When the power transmission unit (400) rotates to the left, the clothes hanger unit (900) can rotate the left side of the mounting unit (950) to the left and the right side of the mounting unit (950) to the right with respect to the hook unit (910). At this time, the angle (I) at which the left side of the mounting unit (950) rotates is the same as the angle (theta) at which the right side of the mounting unit (950) rotates, and the distance at which the left side of the mounting unit (950) moves can be the same as the distance at which the right side of the mounting unit (950) moves.

[0174] As a result, the weight and force moving to the left based on the above-mentioned hanger part (900) are equal to the weight and force moving to the right, so they can cancel each other out.

[0175] Likewise, even if the power transmission unit (400) rotates to the right, the weight and force moving to the left with respect to the clothes hanger unit (900) will be equal to the weight and force moving to the right, and thus will cancel each other out.

[0176] As a result, even if the power transmission unit (400) rotates, the forces applied to the clothes hanger unit (900) can be offset from each other, and as a result, the vibration force, excitation force, and inertial force generated from the clothes hanger unit (900) itself can be minimized. Accordingly, the inertial force generated from the plurality of power transmission units (400) can be minimized, and the vibration or noise generated from the entire moving hanger (100) can be minimized, and the vibration or noise generated from the entire clothing treatment device (1) can be drastically reduced.

[0177] As a result, even if the driving unit (200) rotates at maximum output, vibration may not occur significantly in the moving hanger (100) or the entire clothing treatment device (1).

[0178] Instead, since each surface of the clothes placed on the above-mentioned clothes hanger (900) rotates left and right and is shaken, the shaking force can be greatly secured.

[0179] As described above, the power transmission unit (400) may be provided to penetrate the inner case (20) and receive the power to reciprocate clockwise and counterclockwise. As a result, the power transmission unit (400) may reciprocate left and right while its position is fixed at the top of the inner case (20). The power transmission unit (400) is fixed so that its position does not change up, down, left, or right. In addition, not only the upper part but also the lower part of the power transmission unit (400) is fixed so that its position does not change up, down, left, or right.

[0180] That is, the power transmission unit (400) may be provided to rotate back and forth at a certain angle less than one rotation while the center of rotation is fixed.

[0181] As a result, no matter how fast the power transmission unit (400) rotates, the clothes hanger unit (900) is fixed in position and rotates or moves to one side and the other side, so that the force and vibration transmitted to the power transmission unit (400) can be offset from each other.

[0182] Accordingly, the vibration and noise generated by the power transmission unit (400), the hanging unit (700), and the clothes hanger unit (900) inside the inner case (20) can be minimized.

[0183] As a result, the garment treatment device of the present invention can rotate the driving unit (200) at a higher rpm to reciprocate the power transmission unit (400) at a faster frequency. As a result, the garment treatment device of the present invention can shake the garment more strongly.

[0184] For example, the existing moving hanger (M) of the left-right reciprocating type and the moving hanger (100) of the present invention can be equipped with a driving unit (200) that produces the same output.

[0185] The existing moving hanger (M) has a limitation in that the driving unit (200) cannot be driven above a certain rpm. If the driving unit (200) is driven above a certain rpm, the vibration generated from the clothing may exceed the limit value, and the vibration may damage the existing moving hanger (M) or cause excessive vibration or noise in the clothing treatment device.

[0186] However, the moving hanger (100) of the present invention is provided with a power transmission unit (400) that rotates clockwise or counterclockwise in place. Therefore, as described above, no matter how fast the clothes hanger unit (900) rotates, the vibrations or inertial forces generated by the clothes hanger unit (900) and clothing can be mutually canceled out when transmitted to the power transmission unit (400).

[0187] As a result, even if the driving unit (200) of the present invention is increased to a specific RPM or higher, the moving hanger (100) may not be damaged, and vibration or noise exceeding a limit value may be prevented from occurring in the clothing treatment device.

[0188] Therefore, the clothing treatment device of the present invention can drive the driving unit (200) faster than a clothing treatment device using a conventional moving hanger, and can drive the power transmission unit (400) at a faster frequency to shake the clothing more strongly.

[0189] Accordingly, the clothing treatment device of the present invention can more reliably remove foreign substances on clothing through the moving hanger (100) and more effectively remove wrinkles from clothing.

[0190] In addition, the garment treatment device of the present invention can expose the garment to more steam supplied by drying the garment more quickly.

[0191] In addition, the clothing treatment device of the present invention can freely adjust the RPM of the driving unit (200) to adjust the driving frequency or driving cycle of the power transmission unit (400) according to the course.

[0192] One embodiment of the moving hanger (100) of the present invention may be configured to transmit the power of the driving unit (200) to only one of a plurality of power transmission units (400), and transmit the power transmitted to a specific power transmission unit (400) to the remaining power transmission units (400) through the connecting unit (600).

[0193] The displacement generating unit (300) or the reciprocating rotating unit (500) may be provided to intensively transmit power generated from one driving unit (200) to one power transmission unit (400). The connecting unit (600) may transmit power transmitted to a specific power transmission unit (400) to all power transmission units (400).

[0194] The above connecting part (600) may be provided as a rigid body so that its length does not vary, and may be provided so as to connect all power transmission parts (400).

[0195] Accordingly, all power transmission units (400) can simultaneously rotate in the same direction and at the same angle when the connecting unit (600) moves. As a result, the moving hanger (100) of the present invention can rotate multiple power transmission units (400) back and forth at the same angle simultaneously or simultaneously with one driving unit (200).

[0196] The above moving hanger (100) may include a driving unit (200) that is fixed to the upper portion of the inner case (20) and provides power for moving the power transmission unit, a plurality of reciprocating rotating units (500) that are respectively coupled to the plurality of power transmission units (400) and receive the power from the driving unit (200) and rotate so that the rotation direction is repeatedly changed, and a connecting unit (600) that is provided to connect the plurality of reciprocating rotating units to each other.

[0197] The above connecting portion (600) may include a link bar that is provided to connect the plurality of reciprocating rotating portions (500) and rotate the plurality of reciprocating rotating portions (500) as one unit.

[0198] The above connecting part (600) may be provided in single units.

[0199] The above connecting portion (600) may be provided to connect all of the power transmission portions (400).

[0200] However, if the connecting portion (600) is provided to connect the reciprocating transmission portions (500), the connecting portion (600) can be installed above the support portion (800), thereby preventing it from being exposed inside the inner case (20).

[0201] The above connecting portion (600) is coupled to either the front or rear of the reciprocating rotating portion (500), and at least one of the displacement generating portion (300) and the driving portion (200) can be positioned at the other of the front or rear of the reciprocating rotating portion (500). Accordingly, the connecting portion (600) can be prevented from interfering with the driving portion (200).

[0202] The above connecting portion (600) may be provided to reciprocate in the width direction of the inner case (20) and rotate a plurality of the reciprocating rotating portions (500).

[0203] The above driving unit (200) may include a motor (210) that rotates a rotation shaft (210), a power shaft (240) that is provided to rotate together when the rotation shaft (210) rotates, and a transmission unit (230) that connects the power shaft (240) and the rotation shaft (210) to transmit the rotational force of the rotation shaft (210) to the power shaft (240).

[0204] The above motor (210) may be fixed to the upper portion of the inner case (20) and may be provided to rotate the rotation shaft (220). However, the rotation shaft (220) is provided to rotate at a speed that is too fast compared to the appropriate cycle for reciprocating the power transmission unit (400) in the motor (210). In consideration of this, if the RPM of the rotation shaft is lowered, there is a concern that the output of the motor (210) may not be transmitted to the power transmission unit (400).

[0205] To solve this problem, the transmission unit (230) may be provided to transmit the output of the rotation shaft (220) as is to the power transmission unit (400), but to transmit it by lowering the RPM of the rotation shaft (220).

[0206] The above-mentioned transmission unit (230) is provided to be connected to the rotation shaft (220) and rotate, but is provided to have a diameter larger than the rotation shaft (220) so that it can rotate. Accordingly, the transmission unit (230) can be provided to transmit the torque of the rotation shaft (220) while rotating slower than the RPM of the rotation shaft (220).

[0207] The above power shaft (240) can be provided to rotate by the transmission unit (230), and is provided separately from the rotation shaft (230) and is configured to directly transmit power to the power transmission unit (400).

[0208] The above reciprocating rotation part (500) can be coupled to the power transmission part (400) and provided to be rotatable together with the power transmission part (400).

[0209] The above reciprocating rotating part (500) may include a reciprocating lever (510) coupled to the upper portion of the power transmission part (400) to rotate the power transmission part (400).

[0210] The above reciprocating lever (510) may be provided in the shape of a rib or rod with a center of rotation coupled to the support shaft (410).

[0211] The above reciprocating lever (510) can be respectively coupled to the upper end of a plurality of power transmission units (400), and some of the reciprocating levers (510) can be connected to the transmission unit (230) to receive power from the motor (210).

[0212] The above reciprocating lever (510) may be provided to reciprocate at a certain angle when the transmission unit (230) is rotated by the motor (210). The power transmission unit (400) may be provided to be coupled to the rotation center of the reciprocating lever (510) and rotate together with the reciprocating lever (510).

[0213] A plurality of reciprocating levers (510) can be arranged and connected by a connecting portion (600).

[0214] The above connecting portion (600) may be provided to connect one end of a plurality of reciprocating levers (510).

[0215] Accordingly, when any one of the plurality of reciprocating levers (510) rotates, the connecting portion (600) moves so that the plurality of reciprocating levers (510) can rotate simultaneously and at the same time.

[0216] The power transmission unit (400) and reciprocating lever (510) may be supported on the support unit (800). In addition, the motor (210) and transmission unit (230) may also be supported on the support unit (800).

[0217] Figure 9 illustrates the moving hanger (100) of the present invention separated from the inner case (20).

[0218] The power transmission unit (400) may be provided to extend from the upper part to the lower part of the inner case, and the hanging unit (700) may be coupled to the lower part of the power transmission unit (400).

[0219] The above reciprocating rotation part (500) can be coupled to each of the power transmission parts (400), and can be easily connected to the driving part (200) by being coupled to the upper part of the power transmission part (400).

[0220] The power transmission unit (400) and the reciprocating rotation unit (500) are provided in multiple units and are arranged at a certain distance apart along the width direction of the inner case.

[0221] The above connecting portion (600) is provided to connect a plurality of the power transmission portions (400) or a plurality of the reciprocating rotation portions (500) to each other. Thus, the connecting portion (600) can be provided to rotate a plurality of the power transmission portions (400) or a plurality of the reciprocating rotation portions (500) simultaneously.

[0222] The power transmission unit (400) may include a support shaft (410) that penetrates the upper part of the inner case (20) and is coupled to the reciprocating lever (510).

[0223] The above support shaft (410) may penetrate the support portion (800) and be exposed to the upper portion of the support portion (800) or the upper portion of the inner case (20).

[0224] The power transmission unit (400) may include an auxiliary support unit (420) that is coupled to the support shaft (410) and exposed to the receiving space. The auxiliary support unit (420) may be provided in a rod shape and may be fixed by coupling a hook unit (700) to the lower portion.

[0225] The above auxiliary support member (420) may be fixed to the support shaft (410) and may be provided to rotate together with the support shaft (410). Accordingly, when the support shaft (410) rotates by the reciprocating lever (510), the auxiliary support member (420) coupled to the support shaft (410) also rotates, so that the hook member (700) can also rotate left and right.

[0226] The above reciprocating lever (510) may include a main lever (511) that receives power directly from the driving unit (200) and rotates reciprocally, and an auxiliary lever (512) that receives power from the main lever (511) through a connecting portion (600).

[0227] The above main lever (511) may be provided in a single unit so as to directly receive power from the driving unit (200).

[0228] In the above driving unit (200), the motor (210) may include a vertical motor (211) coupled to the support unit (800) and a vertical rotation shaft (221) rotated by the vertical motor (211).

[0229] The above transmission unit (230) may include a power pulley (231) coupled to the vertical rotation shaft (221) and rotating together with the vertical rotation shaft (221), a transmission pulley (232) coupled to the power shaft (240) and rotating the power shaft (240), and a belt (233) connecting a portion of the outer circumference of the power pulley (231) and the transmission pulley (232).

[0230] The above transmission unit (230) may further include a pulley support unit (224) that rotatably supports the power shaft (240) and the transmission pulley (232). The pulley support unit (224) is provided to support the transmission pulley (232) so that it is arranged parallel to the power pulley (231), and may be provided by being mounted on the support unit (800).

[0231] The above power shaft (240) may be provided to transmit power transmitted from the rotation shaft (220) to one of the two ends of the main lever (511).

[0232] The displacement generating unit (300) can be coupled to the power shaft (240) to receive power. In addition, the displacement generating unit (300) can be connected to the main lever (511) to reciprocate the main lever (511) around the support shaft (410).

[0233] For example, the displacement generating unit (300) may include an eccentric shaft that is eccentrically coupled to the power shaft (240) and rotates a certain radius based on the center of rotation of the power shaft (240).

[0234] The displacement generating unit (300) may be connected to the end of the main lever (511). The displacement generating unit (300) may rotate by the power shaft (240) and reciprocally rotate the end of the main lever (511) around the support shaft (410).

[0235] The above connecting portion (1600) may include a link bar (1610, bar) connecting one end of the main lever (1511) that is not connected to the power shaft (1240) or the displacement generating portion (1300) and one end of the auxiliary lever (1512).

[0236] The above auxiliary lever (1512) may be rotatably connected to the remaining support shaft (1410) that is not connected to the main lever (1511), and may be provided to extend in one direction from the portion connected to the support shaft (1410) and be connected to the link bar (1610).

[0237] The above link bar (610) may be provided in the form of a straight frame connecting one end of the main lever (511) and one end of the auxiliary levers (512). At this time, one end of the main lever (511) and one end of the auxiliary lever (512) may be arranged parallel to each other based on the link bar (610) or the width direction.

[0238] The above link bar (610) may be provided in a single unit and may be provided to simultaneously and simultaneously rotate the main lever (511) and the auxiliary lever (512) around their respective support shafts (410).

[0239] The inner case (20) may be provided with a through hole (23) in which a part of the support part (800) is fixed and the power transmission part (400) is exposed to the receiving space (22).

[0240] The through hole (23) may be provided on the upper surface (22) of the inner case, and the through hole (23) may be provided along the direction in which the power transmission unit (400) is arranged.

[0241] For example, the power transmission units (400) may be arranged spaced apart from each other along the width direction of the inner case, and the through holes (23) may be arranged along the width direction of the inner case.

[0242] The clothing treatment device (1) of the present invention may further include a support frame (12) that is placed outside the inner case and supports the cabinet (1).

[0243] The above support frame (12) may be provided with a metal material that is arranged at each position corresponding to the corner of the cabinet (1) or the corner of the inner case (20) to maintain the appearance of the garment processing device. The support member (800) is supported by being secured at both ends to the support frame (12), thereby preventing unnecessary impact or load from being transmitted to the upper surface (22) of the inner case.

[0244] The above moving hanger (100) may include the power transmission unit (400), the driving unit (200) that provides power to the power transmission unit, and the hanging unit (700) coupled to the power transmission unit, and FIG. 10 illustrates a configuration of the moving hanger in which the hanging unit (700) is coupled to the power transmission unit (400).

[0245] The power transmission unit (400) may be configured with a coupling unit (410) located at the upper end of the power transmission unit (400) to which the driving unit (200) is coupled, a body unit (420) formed by protruding downward from the coupling unit, a hollow portion (430) having one side open inside the body unit, and reinforcing ribs (440) arranged to connect both sides of the power transmission unit inside the hollow portion to divide the hollow portion into upper and lower portions and to reinforce the rigidity of the power transmission unit.

[0246] The power transmission unit (400) may be made of plastic to minimize weight. Furthermore, the power transmission unit (400) may be manufactured by plastic injection molding to facilitate manufacturing. Therefore, since the mold must be removed during manufacturing, the hollow portion (430) may be provided, and a space for installing cooling fins may be provided in the hollow portion.

[0247] However, in injection molding, plastic cannot be made thicker than a certain thickness to prevent shrinkage of the exterior, so the thickness of the plastic may become thinner and its rigidity may be weakened.

[0248] Therefore, a structure may be needed that can reinforce the rigidity of the plastic while securing space for the cooling fins to be installed in a limited space.

[0249] Accordingly, the power transmission unit (400) can secure a space for installing the cooling fins by including the hollow portion (430) with one side open to facilitate injection molding. In addition, the cooling fins and mold can be discharged during injection molding through the open side.

[0250] In addition, in order to reinforce the rigidity weakened by the side effect of plastic injection molding, the reinforcing rib (440) may be provided in the hollow portion (430) to reinforce the rigidity.

[0251] Referring to Fig. 6, the conventional power transmission unit is provided with a plate-shaped reinforcing rib that divides the power transmission unit in the front-back direction, i.e., one side of the reinforcing rib inside the power transmission unit faces forward. The reinforcing rib of the above-mentioned form supports the height direction of the power transmission unit, so it can support the load due to gravity acting on clothing, but has the disadvantage of not being able to support the load due to torsion caused by rotation acting in the width direction of the power transmission unit. However, the moving hanger of the present invention is provided so that the clothing can rotate.

[0252] Accordingly, in order to withstand the load due to torsion acting in the width direction, as shown in Fig. 10, a single reinforcing rib (440) may be arranged to divide the hollow portion (430) into an upper hollow portion (431) and a lower hollow portion (432). By arranging the hollow portion to be divided vertically, the width direction of the power transmission unit (400) can be supported, and thus, the load due to torsion acting in the width direction according to rotation can be supported.

[0253] Fig. 11 illustrates one embodiment of the above reinforcing rib (440).

[0254] The power transmission unit (400) can be formed with a deep hollow portion as shown in Fig. 11(a) to reduce weight, thereby reducing the load applied to the upper surface of the inner case (20) on which the moving hanger (100) is supported. In addition, by reducing the thickness of the plastic, external shrinkage can be prevented during injection molding, making manufacturing easier and reducing material costs. For example, the depth of the hollow portion can be formed to be deeper than half.

[0255] Meanwhile, as shown in Fig. 11(b), the depth of the hollow portion may be formed shallowly to strongly support the interior of the power transmission portion (400) and further reinforce the rigidity of the power transmission portion (400). For example, the depth of the hollow portion may be formed shallower than half.

[0256] The above reinforcing rib (440) may include a first reinforcing rib (441) provided such that one end connected to one side of the power transmission unit is positioned higher than the other end connected to the other side of the power transmission unit. That is, the first reinforcing rib (441) may be provided with an incline formed.

[0257] In addition, the reinforcing rib (440) may include a second reinforcing rib (442) provided such that one end connected to one side of the power transmission unit is positioned lower than the other end connected to the other side of the power transmission unit. That is, the second reinforcing rib may be provided so as to be formed to be inclined in the opposite direction to the first reinforcing rib.

[0258] In addition, the reinforcing rib (440) may include a third reinforcing rib (443) provided such that one end connected to one side of the power transmission unit is positioned at a height corresponding to the other end connected to the other side of the power transmission unit. That is, the third reinforcing rib may be provided parallel to the floor surface.

[0259] The above power transmission unit (400) may include at least one of the first reinforcing rib (441), the second reinforcing rib (442), and the third reinforcing rib (443).

[0260] Although Fig. 11 illustrates that the reinforcing ribs are provided in three numbers, the number may be four or more. As the number of reinforcing ribs (440) increases, the effect of dispersing stress may be achieved. That is, a plurality of the first reinforcing ribs (441) may be arranged spaced apart from each other, a plurality of the second reinforcing ribs (442) may be arranged spaced apart from each other, and a plurality of the third reinforcing ribs (443) may be arranged spaced apart from each other.

[0261] For example, the power transmission unit (400) may be provided with the first reinforcing rib (441) and the second reinforcing rib (442) alternately. At this time, the first reinforcing rib and the second reinforcing rib may be provided so as to be connected. By providing the first reinforcing rib and the second reinforcing rib so as to be connected, the effect of dispersing stress may be achieved.

[0262] That is, the reinforcing rib (440) may have a truss structure.

[0263] In addition, since the points where the first reinforcing rib and the second reinforcing rib are connected in the hollow portion (430) are located at different heights, the reinforcing rib (440) connecting each point can also provide support in the height direction, and thus can support not only the load due to torsion caused by dividing the hollow portion into upper and lower parts, but also the load due to gravity.

[0264] In addition, the second reinforcing rib (442) may not be provided alternately with the first reinforcing rib (441), but may be provided on at least one of the upper and lower portions of a plurality of the first reinforcing ribs. That is, in a truss structure, the number of the second reinforcing ribs may be less than the number of the first reinforcing ribs. This may reduce the weight of the power transmission unit (400).

[0265] Meanwhile, the hollow portion (430) may have a plurality of hollow portions partitioned by a plurality of reinforcing ribs (440).

[0266] That is, the hollow portion (430) may include a first hollow portion (433) positioned above the uppermost reinforcing rib among the plurality of reinforcing ribs (440), a second hollow portion (434) positioned below the lowermost reinforcing rib among the plurality of reinforcing ribs, and a third hollow portion (435) positioned between the first hollow portion and the second hollow portion. That is, the first hollow portion (433) may be positioned at the uppermost end, and the second hollow portion (434) may be positioned at the lowermost end.

[0267] Meanwhile, Fig. 12 illustrates an example of the reinforcing rib (440) in which two first reinforcing ribs (441) are provided and a third reinforcing rib is provided to connect the two first reinforcing ribs (441). However, this is not limited to this, and the third reinforcing rib (443) may be provided on at least one of the upper and lower portions of at least one of the plurality of first reinforcing ribs (441).

[0268] Stress can be distributed at each point where the first reinforcing rib and the third reinforcing rib are connected.

[0269] Fig. 13 illustrates an example of the reinforcing rib (440) in which the third reinforcing rib (443) is arranged spaced apart in the longitudinal direction of the power transmission unit (440). Fig. 13 illustrates three third reinforcing ribs, but the present invention is not limited thereto. As the number of reinforcing ribs increases, the support capacity against stress due to torsion can be further improved.

[0270] Figure 14(a) illustrates that the first reinforcing rib (441) and the second reinforcing rib (442) are provided alternately.

[0271] The above hollow portion (430) may include a first hollow portion (433) positioned above the first reinforcing rib (441) at the top, a second hollow portion (434) positioned below the first reinforcing rib (441) at the bottom, and a plurality of third hollow portions (435) positioned between the first hollow portion and the second hollow portion.

[0272] Since the load supported by the lowest part of the power transmission unit (400) is the greatest, the area of ​​the second hollow section (435) may be the narrowest to support it.

[0273] Meanwhile, since the uppermost part of the power transmission unit (400) is most strongly subjected to the external force by the driving unit (200), the area of ​​the first hollow portion may be the narrowest in order to withstand the load caused by the external force.

[0274] That is, the area of ​​the third hollow part (435) may be wider than the areas of the first hollow part (433) and the second hollow part (434).

[0275] A narrow width may mean that the distance between the point of application where the load is applied and each point where the reinforcing rib (440) is connected to the power transmission unit (400) is short, which may mean that the moment proportional to the distance from the point of application can be reduced.

[0276] Figure 14(b) illustrates that the third reinforcing rib (443) is provided between a plurality of the first reinforcing ribs (441).

[0277] The above hollow portion (430) can reduce the width of the third hollow portion by having the third reinforcing rib (443) positioned lower than half the length of the power transmission portion (400).

[0278] Figure 14(c) illustrates that a plurality of the third reinforcing ribs (443) are provided spaced apart from each other in the longitudinal direction of the power transmission unit (400).

[0279] The above hollow portion (430) may include a first hollow portion (433) positioned above the third reinforcing rib (441) at the top, a second hollow portion (434) positioned below the third reinforcing rib (441) at the bottom, and a plurality of third hollow portions (435) positioned between the first hollow portion and the second hollow portion.

[0280] Since the load supported by the lowest part of the power transmission unit (400) is the greatest, the area of ​​the second hollow section (435) may be the narrowest to support it.

[0281] Meanwhile, since the uppermost part of the power transmission unit (400) is most strongly subjected to the external force by the driving unit (200), the area of ​​the first hollow portion may be the narrowest in order to withstand the load caused by the external force.

[0282] However, although Fig. 14 illustrates three reinforcing ribs (440) and four hollow parts (430), it does not exclude the possibility of having four or more reinforcing ribs and five or more hollow parts. As the number of reinforcing ribs increases, the effect of stress distribution may be enhanced.

[0283] The present invention may be implemented in various modified forms, and its scope is not limited to the embodiments described above. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
