Description

Technology Field

[0001] The present disclosure relates to a garment processing device. More specifically, it relates to a garment support member for holding garments in a garment processing device and a garment processing course using the same. Background Technology

[0002] A garment processing device refers to a device developed for washing and drying clothes and removing wrinkles from clothes in homes and laundries. The concept of a garment processing device includes washing machines for washing clothes, dryers for drying clothes, washer-dryers that have both washing and drying functions, garment care machines for refreshing clothes, and steamers for removing wrinkles from clothes.

[0003] A steamer is a device that supplies steam to clothing to remove wrinkles. Unlike a regular iron, a steamer is a device that removes wrinkles by applying heat to clothing through convection, rather than applying heat directly to the clothing (for example, by bringing the clothing into contact with a hard object).

[0004] In contrast, a garment care device is a mechanism that keeps clothing fresh and clean. It can remove fine dust attached to clothes, deodorize odors, dry clothes, and add fragrance. Additionally, it can prevent static electricity, remove wrinkles using dehumidified air or steam, and sterilize and disinfect clothing.

[0005] In particular, to better implement fine dust removal, wrinkle removal, and clothing drying, the garment care device may include a garment support capable of shaking the entire garment. That is, it may include a garment support capable of reciprocating a hanger bar that holds the garment in a certain direction.

[0006] Prior art Korean Registered Patent No. 10-1285890 discloses a garment support capable of reciprocating motion. Referring to the prior art, a drive unit is disclosed that reciprocates a hanger bar on which a garment hanger is suspended to remove wrinkles and dust adhering to the garment. In the case of the drive unit, even if the rotational speed of the drive unit changes, only the period (or frequency) of the hanger bar changes, while the amplitude of the hanger bar can be maintained. However, under the premise that the amplitude of the hanger bar is maintained, there is a physical limit to shortening the period of the hanger bar or increasing only the corresponding frequency.

[0007] Another prior art document, Korean Registered Patent No. 10-1780223, discloses an example of a control method for a garment care course. However, it merely discloses supplying steam to remove wrinkles from mounted garments and operating a heat pump during the drying process; it makes no mention of wrinkle removal, dust removal attached to the garments, or the amplitude and period of the hanger bar for maximizing the moisture content of the garments during steam supply and improving the degree of drying of the garments. The problem to be solved

[0008] First, the present disclosure addresses the problem of being able to change the amplitude and period of a hanger bar on which clothing is mounted in order to perform functions such as removing dust from clothing or removing wrinkles from clothing in a clothing processing device.

[0009] Second, the present disclosure has as its objective to minimize unnecessary vibration of the hanger bar in directions other than the direction of motion.

[0010] Third, the present disclosure has as its objective to effectively increase the driving force (or excitation force) required for the movement of the hanger bar in the direction of motion by minimizing unnecessary vibrations.

[0011] Fourth, the present disclosure aims to solve the problem of enhancing the effectiveness of a corresponding clothing care function by utilizing the amplitude and period of a hanger bar suitable for each clothing care function.

[0012] Fifth, the present disclosure addresses the problem of minimizing unnecessary noise and vibration by changing the amplitude and period of the hanger bar.

[0013] Fifth, the present disclosure addresses the problem of preventing excessive strain on the product by changing the amplitude and period of the hanger bar.

[0014] Sixth, the present disclosure has the problem of providing an amplitude and cycle suitable for various clothing care functions, such as removing wrinkles from clothing, removing dust attached to clothing, maximizing the moisture content of clothing when steam is supplied, and improving the drying degree of clothing.

[0015] Seventh, the present disclosure has as its objective to provide a clothing care course that improves the performance of clothing care by combining the various clothing care functions mentioned above.

[0057] Preferred embodiments of the present disclosure are described in detail below with reference to the attached drawings. The configuration of the device or the control method described below are intended only to explain the embodiments of the present disclosure and are not intended to limit the scope of the rights of the present disclosure, and reference numerals used identically throughout the specification indicate identical components.

[0058] Specific terms used in this specification are for convenience of explanation only and are not intended to limit the exemplified embodiments.

[0059] For example, expressions such as "identical" and "to be identical" indicate not only a strictly identical state, but also a state where tolerances or differences exist in the degree to which the same function is obtained.

[0060] For example, expressions indicating relative or absolute arrangements, such as "in a certain direction," "along a certain direction," "parallel," "perpendicular," "to the center," "concentric," or "coaxial," not only strictly represent such arrangements but also indicate a state of relative displacement with respect to tolerances or angles or distances to which the same function is obtained.

[0061] To explain the present disclosure, the following description is based on a spatial orthogonal coordinate system formed by mutually orthogonal X-axis, Y-axis, and Z-axis. Each axis direction (X-axis direction, Y-axis direction, Z-axis direction) refers to the two directions in which each axis extends. An axis direction preceded by a '+' sign (+X-axis direction, +Y-axis direction, +Z-axis direction) refers to a positive direction, which is one of the two directions in which each axis extends. An axis direction preceded by a '-' sign (-X-axis direction, -Y-axis direction, -Z-axis direction) refers to a negative direction, which is the other of the two directions in which each axis extends.

[0062] Expressions referring to directions such as “forward (+Y) / backward (-Y) / left (+X) / right (-X) / up (+Z) / down (-Z)” mentioned below are defined according to the XYZ coordinate axes, but this is merely for the purpose of explaining so that the present disclosure can be clearly understood, and it goes without saying that each direction may be defined differently depending on where the reference is placed.

[0063] The use of terms such as 'first, second, third' attached to the components mentioned below is intended solely to avoid confusion regarding the components being referred to, and is unrelated to the order, importance, or master-subordinate relationship between the components. For example, an invention including only the second component without the first component can be implemented.

[0064] As used in this specification, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0065] FIG. 1 illustrates an example of a conventional clothing processing device (1000). A clothing processing device (1000) according to one embodiment of the present disclosure comprises a cabinet (10) having an input port (11) on the front, a first chamber (100) located inside the cabinet (10) and forming a space for receiving clothing through the input port (11), a second chamber (200) located below the first chamber (100) and forming a space separated from the first chamber (100), a hanger bar (693) located in the first chamber (100) and holding clothing received in the first chamber (100), and a driving unit (610) that reciprocates the hanger bar (693) using the rotational force of a motor (620), wherein the driving unit (610) includes the motor (620) and a vibrating body (630) that supports the motor (620) and vibrates alternately in a first rotational direction and a second rotational direction opposite to the first rotational direction by the rotation of the motor (620). It includes a motion conversion unit (680) that rotates in tandem with the vibration body (630) and is connected to the hanger bar (693) to convert the vibration of the vibration body (630) so that the hanger bar (693) can reciprocate along a preset direction of motion. In particular, the hanger bar (693) can reciprocate with different amplitudes and periods depending on the rotational speed of the motor (620).

[0066] The above clothing processing device (1000) is located inside the second chamber (200) and includes a blower unit (220) comprising a blower fan (226) that sucks in air to circulate the air of the first chamber (100), a compressor (234) that compresses a refrigerant, and a heat exchanger (not shown) that exchanges heat with the refrigerant for the air sucked in through the blower unit (220); a heat pump unit (230) connected to the blower unit (220) and discharges dehumidified and heated air through the heat exchanger (not shown) to the first chamber; a steam unit (250) located inside the second chamber (200) that generates and supplies steam; a water supply tank (310) located in front of the second chamber (200) that supplies water to the steam unit (250); and a first chamber (100) and the above located in front of the second chamber (200). It may further include a drainage tank (330) for storing condensate generated from the heat pump unit (230).

[0067] Additionally, the clothing processing device (1000) may include a clothing support member (600) provided inside the first chamber to hang clothing or a clothes hanger. The clothing support member (600) may include a hanger member (690) including a hanger bar (693) provided to hang clothing or a clothes hanger, a driving member (610) that transmits power to enable the hanger member (690) to reciprocate in a preset direction of motion, and a supporting member (670) that supports the driving member (610).

[0068] For example, the hanger bar (693) may reciprocate along the width direction of the cabinet (10), and the length of the hanger bar (693) may be shorter than the width direction length of the cabinet (10).

[0069] The above clothing processing device (1000) may further include a blower unit (220, see FIG. 2) located inside the second chamber (200) for sucking in air from the first chamber (100) and a heat pump unit (230, see FIG. 2) for dehumidifying and heating the sucked-in air and then discharging it to the first chamber (100).

[0070] The cabinet (10) may be made of metal, or may be made of plastic as long as it maintains strength. Additionally, the first chamber (100) may be formed by plastic injection molding. The first chamber (100) may be connected to the cabinet (10) by a frame (not shown), but alternatively, the space between the cabinet (10) and the first chamber (100) or between the cabinet (10) and the second chamber (200) may be filled using foamed plastic such as polyurethane.

[0071] Clothing including tops and bottoms can be placed in the first chamber (100), and can be refreshed through a blower unit (220, see FIG. 2), a heat pump unit (230, see FIG. 2), and a steam unit (250, see FIG. 2) located inside the second chamber (200). That is, through the blower unit (220, see FIG. 2), the heat pump unit (230, see FIG. 2), and the steam unit (250, see FIG. 2) located inside the second chamber (200), steam and / or heated air can be used to sterilize and deodorize the clothing, remove wrinkles formed by use, and dry the clothing.

[0072] The first chamber (100) may include a clothing support member (405) for mounting clothing on the upper part of the first chamber (100). The clothing support member (405) may accommodate a clothes hanger on which clothing is hung. The clothing support member (405) may include a hanger member (690) for shaking the mounted clothing, a driving member (610) for reciprocating the hanger member (690), and a support member (670) for supporting and fixing the clothing support member to the cabinet (10). The hanger member (690) may include a hanger bar (693) provided in the width direction of the cabinet (10) to mount a clothes hanger (H1), and a hanger bar support member (691) that movably supports both ends of the hanger bar. The hanger bar (693) may include a groove-shaped hanger groove (6931) to mount a clothes hanger.

[0073] For example, the drive unit (610) can convert the rotational motion of the motor (620) provided in the drive unit (610) into a vibrational motion that rotates alternately in a first rotational direction and a second rotational direction opposite to the first rotational direction. The vibrational motion can be converted into a reciprocating motion of the hanger bar (693) by a motion conversion unit to be described later. The rotational motion of the drive unit (610) will shake the clothing (T) mounted on the hanger bar (693). Through this, the clothing mounted on the clothing support unit (405) can be shaken to remove foreign substances, including dust attached to the clothing, restore the texture of the clothing such as fur, and perform clothing care functions such as wrinkle removal.

[0074] In particular, the garment care function can be performed more effectively by exposing the garment mounted on the garment support (405) to steam or moisture supplied from the second chamber (200) while shaking it. FIG. 1 shows an example of such a garment support (405) inside a circle indicated by a dotted line. Such a garment support (600) can be referred to as a moving hanger, and in a narrower sense, it may refer to a reciprocating hanger bar.

[0075] That is, when a garment is placed on the garment support (405), it can be placed in a spread-out state due to its own weight inside the first chamber (100). The hanger grooves (6931) located on the hanger bar (693) may be provided in multiple numbers at a predetermined distance apart, which allows the surface of the garment to be evenly exposed to dehumidified and heated air and / or steam supplied from the second chamber (200).

[0076] Generally, water boils at 100°C under atmospheric pressure, and the resulting steam can be referred to as steam. In contrast, water refers to water in the form of small water droplets, less than 1 mm in size, suspended in the air at room temperature. For example, it is similar to fog. Generally, steam generated by heating and boiling water has superior sterilizing power due to its higher temperature compared to water. Furthermore, because water molecules move more actively at higher temperatures, it has excellent penetrability into clothing, making steam more suitable than water for refreshing garments.

[0077] The first chamber (100) is formed by a first chamber upper surface (101) where the driving part (610) of the clothing support part (405) is located on the upper side, a first chamber bottom surface (102) forming the bottom, a first chamber side surface (103) forming the side of the first chamber (100) connecting the first chamber upper surface (101) and the first chamber bottom surface (102), and a rear surface of the first chamber. If the side where the input port (11) is formed is the front surface, the rear surface of the first chamber will be located in the opposite direction.

[0078] The bottom surface (102) of the first chamber may have an air supply port (111) and a steam supply port (112) for supplying steam generated by the steam unit (250) inside the second chamber (200) and air dehumidified and heated by the heat pump unit (230) to the first chamber (100), and an air intake port (115) for re-inhaling the air of the first chamber (100) using a blower unit (220).

[0079] The air intake port (115) can also be used to discharge condensate formed from steam in the first chamber (100). That is, the condensate generated on the inner surface of the first chamber (100) will flow or fall to the bottom surface (102) of the first chamber due to its own weight. The bottom surface (102) of the first chamber forms an inclined surface toward the air intake port (115), so the condensate will naturally move toward the air intake port (115). The condensate discharged through the air intake port (115) will eventually flow down through the inlet duct (221, see FIG. 2) and be temporarily stored in a sump (not shown) located at the lower inner side of the inlet duct.

[0080] Likewise, condensate generated on the inner surface of the door (401) will travel along the door liner (420) provided on the inner surface of the door and fall to the bottom surface of the first chamber, and will be discharged into a sump (not shown) through the air intake port (115). The condensate collected in the sump will be discharged into a drainage tank (330) through a drainage pump (339, see FIG. 2) and collected.

[0081] Referring to FIG. 1, the air supply port (111) and the steam supply port (112) may be provided in the area where the bottom surface (102) of the first chamber and the rear surface of the first chamber (100) meet. Additionally, the area where the bottom surface (102) of the first chamber and the rear surface of the first chamber meet may be smoothly sloped.

[0082] The air intake port (115) may be located close to the inlet (11) on the bottom surface (102) of the first chamber. Accordingly, the air inside the first chamber (100) can form a circulation structure in which it is discharged through the air supply port (111) and sucked in through the air intake port (115). Steam will also be discharged through the steam supply port (112), condensed, sucked in through the air intake port (115), and then collected in a sump (not shown) that stores the condensate.

[0083] In order to more smoothly discharge the condensate condensed inside the first chamber (100) into the second chamber (200) through the air intake port (115), the bottom surface (102) of the first chamber may be sloped downward from the rear of the first chamber (100) toward the direction of the air intake port (115).

[0084] As illustrated in FIG. 1, the clothing processing device (1000) may be provided with a water supply tank (310) for supplying water to a steam unit (250) and a drainage tank (330) for discharging and storing condensate collected in a sump (not shown) in the front part of the second chamber (200). Additionally, a tank module frame (351) is provided to form a tank installation space (351) in which the water supply tank (310) and the drainage tank (330) are installed, thereby separating the tank installation space (351) from the second chamber (200). That is, the tank installation space (351) and the second chamber (200) are located at the bottom of the first chamber (100), and the tank installation space (351) may be located closer to the door (400) than the second chamber (200). A second chamber (200) may be located behind the tank installation space (351) mentioned above.

[0085] The above water supply tank (310) and drainage tank (330) may be provided so as to be detachably attached to a tank module frame (not shown), respectively. Alternatively, the water supply tank (310) and drainage tank (330) may be combined into one unit and provided so as to be detachably attached at the same time.

[0086] The door (400) may include a door inner surface (401) located at the rear of the door (400) or in a direction toward the first chamber (100) from the door (400) when the door (400) is closed. The door (400) will be rotatably connected to the cabinet (10) by a hinge connection method to open and close the input opening (11). To this end, the door (400) may include door hinges (411, 412) for rotational connection.

[0087] When the user closes the door (400), the front of the water supply tank (310) and the front of the drainage tank (330) face the inner surface of the door (401), and when the user opens the door (400), the front of the water supply tank (310) and the front of the drainage tank (330) may be exposed to the outside.

[0088] The front surfaces of the water supply tank (310) and the drainage tank (330) are each provided with a transparent or translucent material, so that when the door (400) is opened, the water level of the water supply tank (310) and the drainage tank (330) can be checked immediately. Alternatively, the water supply tank (310) and the drainage tank (330) each include a water supply tank window (not shown) and a drainage tank window (not shown) on a part of their respective front surfaces, so that the water level of the water stored inside the water supply tank (310) and the drainage tank (330) can be checked.

[0089] The front of the water supply tank (310) and the front of the drainage tank (330) may each include a water supply tank handle (315) and a drainage tank handle (335). When a user pulls the water supply tank handle (315) and the drainage tank handle (335), the water supply tank (310) and the drainage tank (330) may rotate around the front end of the water supply tank and the front end of the drainage tank, respectively, and be separated from the tank module frame (not shown). In addition, when mounting to the tank module frame (not shown), the water supply tank (310) and the drainage tank (330) will be seated on the tank module frame (not shown) through rotation.

[0090] The door (400) may further include a sealing portion (430) to prevent steam supplied to the first chamber (100) by the steam unit (250, see FIG. 2) from escaping, and a door liner (420) provided on the inner surface of the door (401) to guide condensate generated on the inner surface of the door (401) to be discharged through the air intake port (115).

[0091] The sealing portion (430) can seal the space between the door (400) and the cabinet (10) when the door (400) is closed, thereby preventing steam or condensed water from leaking out. The sealing portion (430) may be provided in a form that wraps around the edge of the inner surface (401) of the door. The sealing portion (430) can also perform the function of cushioning the impact between the cabinet (10) and the door (400) when the door is closed.

[0092] The sealing portion (430) may include a first gasket (431) provided with a size corresponding to the front of the first chamber (100) in a part of the inner surface of the door (401), and a second gasket (432) provided with a size corresponding to the front of the tank installation space (351) in which the water supply tank (310) and drainage tank (330) are installed in a part of the inner surface of the door (401).

[0093] The first gasket (431) seals the first chamber to prevent condensate generated in the first chamber (100) and the inner surface of the door (401) from flowing into the tank installation space (351). The second gasket (432) is located below the first gasket (431) to prevent steam or moisture from escaping to the outside through the tank installation space (351).

[0094] Among the first gaskets (431), the lower gasket (4311) provided in the width direction of the door (400) to seal the lower part of the first chamber (100), and among the second gaskets (432), the upper gasket (4321) provided in the width direction of the door to seal the upper part of the tank installation space (351) are positioned between the first chamber (100) and the tank installation space (351) and can come into contact with the front part (119) facing the inner surface (401) of the door.

[0095] The door liner (420) is coupled to the inner surface of the door (401) and can serve as a guide to allow condensate generated on the inner surface of the door (401) to move to the air intake port (115). That is, the door liner (420) can be provided in a shape that protrudes and slopes downwards from the inner surface of the door (401). The length of the lower end of the door liner (420) protruding from the inner surface of the door (401) can be such that the lower end of the door liner (420) is positioned above the air intake port (115). Accordingly, condensate flowing downwards along the door liner (420) can fall from the lower end of the door liner (420) and be discharged directly to the air intake port (115).

[0096] In contrast, condensate falling from the door liner (420) toward the bottom surface (102) of the first chamber can be guided by a separate guide member provided on the bottom surface (102) of the first chamber and discharged into the air intake port (115).

[0097] In the inner surface of the door (401) or the interior of the first chamber (100), a lower garment (or trousers P) is placed on a trouser hanger (H2), and a garment hanging part (405) for hanging the trouser hanger (H2) and a pressing part (500) for pressing the trousers (P) fixed by the garment hanging part (405) may be located.

[0098] The reason for hanging the above pants (P) upside down, that is, with the bottom hem facing upward, is that the weight of the waist portion of the pants (P), i.e., the upper portion of the pants (P), is heavier than the weight of the lower portion of the pants (P), i.e., the leg portion, so that the pants (P) can be spread out evenly to some extent by the weight of the pants (P).

[0099] The above-mentioned pressure member (500) may include a base plate (520) that supports the clothing by being coupled to the inner surface of the door (401), and a pressure plate (510) that rotates toward the base plate (520) to apply pressure to the pants (P). When the pressure plate (510) rotates toward the base plate (520), it becomes possible to apply pressure to the pants (P).

[0100] To this end, the pressure member (500) may further include a pressure member hinge (518) for hinge connection between the pressure plate (510) and the base plate (520) for rotation of the pressure plate (510), and a pressure plate fixing member (519) for connecting and fixing the pressure plate (510) and the base plate (520).

[0101] After placing the trousers (P) between the pressure plate (510) and the base plate (520), closing the door (400) and exposing it to steam and hot air can remove wrinkles from the trousers (P) and form sharp creases, so-called sharp creases, in the leg portion.

[0102] To achieve this, since it must be easy for steam to penetrate into the pants (P), a steam penetration hole (515) penetrating the pressure plate (510) may be included. Additionally, to prevent the seam provided along the longitudinal direction of the pants from being pressed, a first recess (516) and a second recess (517) may be further included on the upper and lower sides of the steam penetration hole (515), respectively, on the side of the pressure plate (510) that contacts the pants (P).

[0103] Meanwhile, the base plate (520) may be provided with an elastic material to support the pressed clothing, or may further include an elastic member that elastically supports the base plate from the door.

[0104] After placing the pants (P) on the clothing mounting part (405), when the pressure plate (510) is connected to the base plate (520) by rotation, the lower part of the base plate may further include a clothing fixing part (540) to prevent the pants (P) from sliding.

[0105] The above clothing fixing part (540) is provided in the form of a rod and can be provided at a predetermined distance from the lower part of the base plate. In this case, the height of the pressure plate (510) is longer than the height of the base plate (520), so that when the pressure plate (510) is rotatably coupled to the base plate (520), the clothing fixing part (540) can be covered.

[0106] Referring to FIG. 1, the garment fixing part is provided in the form of a single long rod and is shown as an example of a type that fixes the garment by rotating at one end. However, alternatively, it may be provided in the form of a clip located at both ends of the pressure part (500) to fix both sides of the pants (P).

[0107] The above-mentioned pressure member (500) may include a side fixing member (530) located between the base plate (520) and the door liner (420) to prevent the pants (P) mounted on the clothing fixing member (540) from shaking to the sides.

[0108] Referring to FIG. 2(a), the interior of the second chamber (200) may include a blower unit (220) for sucking in air from the first chamber (100), a steam unit (250) that receives water from the water supply tank (310), generates steam, and then supplies steam to the first chamber (100), and a heat pump unit (230) that dehumidifies and heats the air sucked in by the blower unit (220) and then discharges it to the first chamber (100). The steam unit (250), the blower unit (220), and the heat pump unit (230) may be installed on a base (210).

[0109] A supporter part (280) that supports the steam unit (220) and the heat pump unit (230) may be coupled to the base (210). The supporter part (280) may include a first supporter (281) located closer to the blower unit and a second supporter (282) located further away from the blower unit.

[0110] A heat pump unit (230) may be located on the upper part of the supporter section (280), and a steam unit (250) may be located in a receiving area (S) formed on the inner side of the supporter section (280), that is, between the supporter section (280) and the base (210). Additionally, a control unit (270) for controlling the blower unit (220), the steam unit (250), and the heat pump unit (230) may be located in the receiving area (S).

[0111] However, this is merely an example, and the control unit (270) may be located at the rear of the second chamber (200). When located at the rear of the second chamber (200), the control unit (270) may be attached or detached through a rear panel (not shown) located at the rear of the cabinet that communicates with the second chamber (200).

[0112] The above control unit (270) can also control the pressurizing unit (500) described later. It can also control the reciprocating motion of the clothing support unit (600, see FIG. 1).

[0113] The steam unit (250) is provided to sterilize, deodorize, and remove wrinkles from clothing placed in the first chamber (100), and the blower unit (220) and the heat pump unit (230) may be provided to circulate air in the first chamber (100) and dehumidify through heat exchange.

[0114] Referring to FIG. 2(b), the blower unit (220) may include a blower fan (226) and an inlet duct (221). When the direction in which the inlet port (11) is located is referred to as the front and the direction in which the rear of the first chamber is located is referred to as the rear, the inlet duct (221) is provided in front of the blower fan (226), and a tank module frame may be provided in front of the inlet duct (221). Accordingly, the tank module frame forms a tank installation space (351) and can separate the tank installation space (351) from the second chamber (200).

[0115] The water supply tank (310) and the drainage tank (330) that are seated on the tank module frame may be positioned closer to one of the two sides of the cabinet (10). For example, the water supply tank (310) may be positioned closer to the right side of the cabinet (10) than to the left side of the cabinet in the tank installation space (351), and conversely, the drainage tank (330) may be positioned closer to the left side of the cabinet (10) than to the right side of the cabinet (10).

[0116] The steam unit (250) can also be positioned so that the right side of the cabinet (10) is closer than the left side of the cabinet (10) inside the second chamber (200), just like the position of the water supply tank (310). This is to simplify the connection path for water to move from the water supply tank (310) to the steam unit (250) by placing the steam unit (250) behind the water supply tank (310).

[0117] The steam unit (250) may include a storage unit (251) in which water is stored, and a heater (2501) located inside the storage unit (251) to heat the water. Additionally, it may further include a steam temperature sensor (9131) for measuring the temperature of the water stored in the storage unit (251).

[0118] Water located in the storage unit (251) can be heated through the heater (2501). The steam generated through heating can be supplied to the first chamber (100) through a steam supply port (112) provided on the bottom surface (102) of the first chamber along a steam path (not shown).

[0119] Water used in the above steam unit (250) can be supplied through a water supply tank (310). When the above water supply tank (310) is placed in the tank installation space (351), a water supply check valve (not shown) provided on the bottom surface of the above water supply tank (310) is opened, and water is supplied to the storage unit (251) through a water supply path connected to the water supply check valve.

[0120] If the water supply tank (310) is located closer to the left side of the cabinet (10) than to the right side of the cabinet (10), the steam unit (250) may also be located closer to the left side of the cabinet (10) than to the right side of the cabinet (10) in correspondence. This is to reduce the length of the water supply passage (not shown) connecting the water supply tank (310) and the steam unit (250) and to simplify it as much as possible.

[0121] The blower unit (220) can draw in air through an air intake port (115) and an inlet duct (221) located on the bottom surface (102) of the first chamber to circulate air in the first chamber (100). The inlet duct (221) may include an inlet duct inlet (2213) provided with a shape corresponding to the air intake port (115), an inlet duct body (2211) that moves the drawn-in air to a blower fan (226), and an inlet duct outlet (2215) connected to the inlet of the blower fan (226).

[0122] The above-mentioned blower fan (226) is a type of centrifugal blower and can discharge the sucked-in air using centrifugal force. The above-mentioned blower fan (226) can be connected to the heat pump unit (230) through the blower housing (224). Accordingly, the air sucked in through the blower fan (226) will be connected to the air inlet (2311) of the duct housing (231), which is connected to the blower outlet (2242) of the blower housing (224).

[0123] The heat pump unit (230) may include a duct housing (231) which is a passage for air to move, an air inlet (2311) located at one end of the duct housing (231) for drawing in air from a blower fan (226), and an air outlet (2312) located at the other end of the duct housing (231) for discharging air into the first chamber (100).

[0124] The heat pump unit (230) may further include a first heat exchanger (not shown) and a second heat exchanger (not shown) located inside the duct housing (231) to exchange heat with the sucked air. Additionally, the heat pump unit (230) may further include a compressor (234) located outside the duct housing (231) to compress and circulate a refrigerant to supply it to the first heat exchanger and the second heat exchanger.

[0125] The compressor (234) may be located on the side of the supporter (280). Since the water supply tank (310) is located close to one side of the cabinet (10), and the steam unit (250) and the supporter (280) are also located close to one side of the cabinet (10) inside the second chamber (200), the compressor (235) may be located close to the other side of the cabinet (10) on one side of the cabinet (10). For example, referring to FIG. 2(b), the compressor (235) is positioned off to the right (closer to the right side than the left side of the cabinet), and the supporter (280) and the steam unit (250) are positioned off to the left (closer to the left side than the right side of the cabinet).

[0126] Additionally, the inlet duct (221) may include an inlet duct inlet (2213) that draws in air from the first chamber (100) by communicating with the air intake port (115) provided on the bottom surface (102) of the first chamber. Additionally, the inlet duct inlet (2213) may form an inclined flow path. This is to allow condensate formed in the first chamber (100) and the door (400) to easily move through the inlet duct inlet (2213) communicating with the bottom surface (102) of the first chamber, along the inclined flow path, to a sump (not shown) provided on the inner lower side of the inlet duct (221).

[0127] An inlet duct (221) may be located in front of the blower fan (226), and a steam unit (250) and a heat pump unit (230) may be arranged behind the blower fan (226). Additionally, the heat pump unit (230) may be supported by a supporter part (280). The supporter part (280) may be coupled to a base (210) that forms the bottom of the second chamber (200). Thus, the supporter part (280) may form a predetermined distance between the base (210) and the heat pump unit (230), and may form a predetermined receiving area (S) between the supporter part (280) and the base (210).

[0128] A steam unit (250) is located in the above receiving area (S) and can be coupled with the supporter part (280) in the above receiving area (S). Additionally, the steam unit (250) can be coupled with the supporter part (280) while spaced apart from the base (210).

[0129] Unlike what is shown in FIG. 2(b), the blower unit (220) may be provided inside the duct housing (231) to circulate the air of the first chamber (100). Alternatively, it may be installed between the air outlet (2312) and the second heat exchanger (or condenser).

[0130] In the above duct housing (231), condensate may be generated through heat exchange between the first heat exchanger (or evaporator) and the sucked air. The condensate generated in the heat pump unit (230) may move to a sump (not shown) through the bottom surface of the duct housing (231) and be discharged to a drain tank (330).

[0131] The air and / or steam supplied by the heat pump unit (230) and the steam unit (250) may be applied to clothing contained within the first chamber (100) to affect the physical or chemical properties of the clothing. For example, the fabric structure of the clothing may be relaxed by hot air or steam, causing wrinkles to be smoothed out, and unpleasant odors may be removed by odor molecules embedded in the clothing reacting with the steam. In addition, the hot air and / or steam supplied by the heat pump unit (230) and the steam unit (250) may sterilize bacteria inhabiting the clothing.

[0132] FIG. 3(a) is an example of a clothing support member. The clothing support member (700) may include a hanger member (790) on which clothing is placed, a driving member (710) for reciprocating the hanger member (790) to shake the placed clothing, and a supporting member (670) for supporting and fixing the driving member to the support frame (15).

[0133] The hanger section (790) may include a hanger bar (793) for holding clothing, a plurality of hanger grooves (7931) provided on the hanger bar (793) for holding a clothes hanger (H1), and hanger support sections (7911, 7912) that support both ends of the hanger bar (793).

[0134] The fact that the hanger bar (793) holds clothing generally means that a clothes hanger (H1) holding clothing is placed in the hanger groove (7931). However, alternatively, clothing can also be placed directly on the hanger bar (793) for use. In this case, the hanger bar (793) can hold clothing like a clothes rack.

[0135] The above drive unit (710) may be located between the first chamber (100) and the cabinet (10) so as not to be seen from the first chamber (100). To this end, the garment processing device may further include a support frame (15) for accommodating and supporting the drive unit (710). And, only the hanger bar support members (7911, 7912) that support both ends of the hanger bar (793) may penetrate the support frame (15) and be inserted into the interior of the first chamber (100).

[0136] The above drive unit (710) may include a motor (720) that generates rotational force. The motion conversion unit (780) can convert the rotational motion of the motor (720) into linear motion moving in the width direction of the cabinet, thereby moving the hanger bar (793) along the width direction of the cabinet (10). If the rotation direction of the motor (720) is alternately switched, the hanger bar (793) will reciprocate along the width direction of the cabinet.

[0137] To this end, FIG. 3(b) illustrates a rack (782) and a pinion (781) connected to and rotating with the motor (720) as an example of a motion conversion unit (780). However, this is for illustrative purposes only, and the motion of the drive unit (710) may be converted into the reciprocating motion of the hanger bar (793) in a different way. For example, the drive unit (710) may be equipped with an actuator capable of linear reciprocating motion. In this case, a separate motion conversion unit may not be required. Alternatively, the drive unit (710) may be equipped with a linear motor, and the reciprocating motion of the hanger bar (793) may be realized by controlling the direction of motion of the linear motor. Alternatively, to convert the rotational motion of the motor into linear reciprocating motion, a rotating plate may be provided on the rotation axis of the motor, and a rod connected to a part off-center of rotation of the rotating plate may be used to convert the rotational motion of the motor into the reciprocating motion of the rod.

[0138] Referring to FIGS. 4 through 10, the clothing support member (600) may be positioned on the upper part of the cabinet (10). Specifically, the driving member (610) may be located between the upper panel (12) forming the upper surface of the cabinet (10) and the upper surface (101) of the first chamber. A support frame (15) for supporting the driving member (610) may be located between the upper panel (12) and the upper surface (101) of the first chamber. The clothing support member (600) may be supported by the support frame (15).

[0139] Referring to FIG. 4, the support frame (15) may form a support space (15S) in which the clothing support member (600) is accommodated. The support space (15S) may be formed by the support frame (15) being recessed. The support frame (15) may also serve as a support for installing a lighting device (not shown) to illuminate the interior of the first chamber (100).

[0140] The above clothing support member (600) may largely include a hanger member (690) and a driving member (610). The hanger member (690) may include a hanger bar (693) on which clothing is mounted and a hanger bar support member (691) that supports both ends of the hanger bar (693) and is movably connected to the support frame (15). The driving member (610) may generate power for the reciprocating motion of the hanger bar (693). To this end, the driving unit (610) may include the motor (620), a vibrating body (630) that supports the motor (620) and vibrates alternately in clockwise and counterclockwise directions by the rotation of the motor (620), and a motion conversion unit (680) that rotates in unison with the vibrating body (630) and is connected to the hanger bar (693) to convert the vibration of the vibrating body (630) so that the hanger bar (693) can reciprocate along a preset direction of motion.

[0141] The above-mentioned hanger unit (690) may be provided to hang clothing or a clothes hanger. The above-mentioned hanger unit (690) may be supported by the inner surface of the cabinet (10), the first chamber (100), or by a support frame (0). FIG. 4 illustrates an example in which the above-mentioned hanger unit (690) is supported by the support frame (15). The above-mentioned hanger unit (690) is connected to a driving unit (610) and may receive vibrations from the driving unit (610). The vibrations generated by the driving unit (610) will be converted into reciprocating motion tracing an arc by the motion conversion unit (680), and then converted into nearly linearized reciprocating motion of the hanger bar (693).

[0142] FIGS. 5(a) to 5(c) are views from above of the support frame (15), the driving unit (610), and the upper surface (101) of the first chamber.

[0143] Referring to FIG. 5(a), the garment support member (600) is shown as being supported by a support frame (15) in a top view. Accordingly, an example of a driving member (610) is mainly illustrated. The driving member (610) includes a motor (620) located in the center and eccentric members (634, see FIG. 5) positioned on each side of the motor, and the eccentric members (634) are connected by a vibrating body (630) so as to rotate as a single unit. Additionally, the vibrating body (630) can rotatably support a motor rotation shaft (625) that rotates by the rotational force generated by the motor (620).

[0144] Each of the above eccentric parts (634) can rotate around each first rotation axis (Ow1) and second rotation axis (Ow2). Additionally, the motion conversion part (680), which is coupled with the vibration body (630) and protrudes toward the hanger bar, can be extended along the connecting axis (Oh) toward the first chamber (100).

[0145] The support member (670) is fixed to the cabinet (10). The support member (670) may be fixed to the support frame (15). The support member (670) may support the drive unit elastic member (635). Additionally, the support member (670) may support the drive unit (610). That is, the support member (670) may rotatably support the drive unit (610). That is, the support member (670) may rotatably support the drive unit (610) around the central axis (Oc).

[0146] The hanger section (690) may further include a hanger bar support section (691) that enables both ends of the hanger bar (693) to reciprocate. Additionally, the hanger section (690) may further include a support bar fixing section (697) that rotatably connects the hanger bar support section (691) to the support frame (15).

[0147] Referring to FIG. 5(b), an example of a support frame (15) is illustrated. The support frame (15) may include a support space (15S) in which the drive unit (610) is accommodated. The support space (15S) may be formed by the support frame (15) being recessed toward the first chamber (100). The bottom surface of the support space (15S) may include a central through hole (153) that penetrates in the height direction of the cabinet. This is to allow the motion conversion unit (680) to be inserted and connected to the hanger bar (693).

[0148] Additionally, the bottom surface of the support space (15S) may further include a lighting penetration hole (154) for installing a lighting device for illuminating the first chamber (100).

[0149] Additionally, the support space (15S) may further include a first support through-hole (151) and a second support through-hole (152) penetrating in the height direction of the cabinet (10) so that the hanger bar support part (691) can be rotatably connected and fixed on both sides thereof. A first support bar (6911) and a second support bar (6912) supporting both ends of the hanger bar (693) will be inserted into the first support through-hole (151) and the second support through-hole (152), and will be connected to the support frame (15) by the first fixing part (6971) and the second fixing part (6972), respectively.

[0151] That is, the motion conversion unit communication hole (1013) can be formed by penetrating the upper surface (101) of the first chamber so that the motion conversion unit (680) inserted through the central penetration hole (153) can be inserted into the interior of the first chamber (100). Similarly, the chamber lighting communication hole (1014) can be provided for the insertion of a lighting device (not shown). And the first support bar (6911) and the second support bar (6912) can be inserted into the interior of the first chamber (100) through the first upper communication hole (1011) and the second upper communication hole (1012), respectively, and connected to both ends of the hanger bar (693).

[0152] FIG. 6 is a cross-sectional view of the clothing support member (600) seen from one side of the cabinet (10). Referring to FIG. 5(c) and FIG. 6, a portion of the clothing support member (600) may be located between the upper panels (12) of the upper surface (101) of the first chamber. In particular, a support frame (15) may be located between the upper panels (12) of the upper surface (101) of the first chamber, and the support frame (15) may include a support space (15s) that accommodates a portion of the clothing support member (600).

[0153] The apparatus further comprises a first support bar (6911) and a second support bar (6912) that reciprocally support both ends of the hanger bar (693), a support frame (15) that supports the drive unit (610) located between the first chamber (100) and the upper panel (12), a first fixing part (6971) and a second fixing part (6972) that rotatably support the first support bar (6911) and the second support bar (6912) on the support frame (15), and a first chamber upper surface (101) that forms the upper surface of the first chamber (100), wherein the support frame (15) has a central through hole (153) that penetrates the support frame (15) in the height direction of the cabinet (10) and is located in opposite directions along the width direction of the cabinet (10) with the central through hole (153) as the center, thereby supporting the support frame (15). It may include a first support through hole (151) and a second support through hole (152) penetrating in the height direction of the cabinet (10). Additionally, the upper surface of the first chamber (101) may further include a motion conversion unit communication hole (1013) penetrating the upper surface of the first chamber (101) provided to correspond to the central through hole (153), and a first upper communication hole (1011) and a second upper communication hole (1012) penetrating the upper surface of the first chamber (101) provided to correspond to the first support through hole (151) and the second support through hole (152). Additionally, the first support bar (6911) is connected to the first fixing part (6971) and inserted into the first support through hole (151) and the first upper communication hole (1011) to be connected to one end of the hanger bar (693), and the second support bar (6912) is connected to the second fixing part (6972) and inserted into the second support through hole (152) and the second upper communication hole (1012) to be connected to the other end of the hanger bar (693).

[0154] Referring to FIG. 6, the hanger portion (690) may further include a slot (694) located on the hanger bar (693) that converts the reciprocating motion of the motion conversion portion (680) into a reciprocating motion that moves along the direction of motion. Additionally, it may further include a slot cover (695) that protects the slot (694) and the motion conversion portion (680) so that they are hidden from the user's visual view.

[0155] Additionally, the motion conversion unit (680) rotates integrally with the vibration body (630) when the vibration body (630) rotates, and can be inserted into the slot (694) by protruding from the vibration body (630) of the driving unit (610). Accordingly, the hanger bar (693) can reciprocate by the motion conversion unit (680).

[0156] Referring to FIG. 6, a part of the clothing support (600), such as a hanger bar (693), may be exposed inside the first chamber (100). This is to conceal the complex configuration of the drive unit (610) and to make the first chamber (100) exposed to the user look neat in terms of design.

[0157] Additionally, the support member (670) can be fixed to the support frame (15). The support member (670) can support the drive unit elastic member (635). And, the support member (670) can support the drive unit (610).

[0158] Referring to FIG. 7, the hanger portion (690) includes a hanger bar (693) provided to hang clothing or a clothes hanger. In this embodiment, the hanger bar (693) may include a hanger groove (6931) to allow a clothes hanger to be hung. However, in other embodiments, the hanger bar (693) may be provided with a hook (not shown) or the like so that clothes can be hung directly.

[0159] The above drive unit (610) can reciprocate (vibrate) the hanger bar (693). The above drive unit (610) is connected to the hanger bar (693) and transmits the vibration of the drive unit (610) to the hanger bar (693).

[0160] The hanger bar (693) may be supported by a support frame (15). For example, both ends of the hanger bar (693) may be connected to the support frame (15) through a hanger bar support portion (691). The hanger bar (693) may be movably positioned with respect to the cabinet (10), the support frame (15), or the first chamber (100). The hanger bar (693) may be configured to vibrate by reciprocating in a predetermined vibration direction (+X, -X) or a predetermined movement direction. The hanger bar (693) may vibrate in the vibration direction (+X, -X) with respect to the cabinet (10).

[0161] That is, the hymn hanger bar (693) can reciprocate in the vibration direction (+X, -X) by means of the drive unit (610). The hanger bar (693) can reciprocate while suspended from the upper part of the first chamber (100).

[0162] The above hanger bar (693) may be formed to extend long in the vibration direction (+X, -X), that is, in the width direction of the cabinet (10). However, the extended length will be shorter than the width direction length of the cabinet (10). A plurality of hanger grooves (6931) may be arranged spaced apart from each other in the vibration direction (+X, -X) on the upper side of the hanger bar (693). Each of the hanger grooves (6931) may be formed to extend in a direction (+Y, -Y) across the vibration direction (+X, -X) or in the depth direction of the first chamber (100).

[0163] The hanger section (690) may include a hanger support section (691) that supports both ends of the hanger bar (693) so as to be movable. That is, the hanger support section (691) is movable in the direction of vibration or movement (+X, -X). Additionally, the hanger support section (691) may be formed of a flexible material so that the hanger bar (693) can move. The hanger support section (691) may include an elastic member that can elastically deform when the hanger bar (693) moves. The upper end of the hanger support section (691) is connected to the support frame (15), and the lower end will be connected to one of the two ends of the hanger bar (693). To this end, the hanger bar support member (691) may include a first support bar (6911) connected to one end of the hanger bar (693) and a second support bar (6912) connected to the other end of the hanger bar (693).

[0164] The upper end of the above-mentioned hanger bar support part (691) may be rotatably or movably connected to the support frame (15) by a support bar fixing part (697). The support bar fixing part (697) may include a first fixing part (6971) and a second fixing part (6972). The first fixing part (6971) and the second fixing part (6972) will be connected to the upper ends of the first support bar (6911) and the second support bar (6912), respectively, and will be coupled to the support frame (15).

[0165] Meanwhile, the upper part of the above-mentioned hanger support portion (691) can be hung by being hooked onto the above-mentioned support bar fixing portion (697). The above-mentioned support bar fixing portion (691) is formed in a horizontal plate shape, and the above-mentioned support bar fixing portion (691) can be positioned to penetrate the upper part of the hanger support portion (691).

[0166] The above-mentioned hanger bar support portion (691) is located inside a support guide portion (692) in the form of a hollow pipe, and can connect the support bar fixing portion (697) and the hanger bar (693). The support guide portion (692) may include a first support guide (6921) and a second support guide (6922). Accordingly, the first support bar (6911) can penetrate the interior of the first support guide (6921) to connect the first fixing portion (6971) and one end of the hanger bar (693). The second support bar (6912) can penetrate the interior of the second support guide (6922) to connect the second fixing portion (6972) and the other end of the hanger bar (693).

[0167] The support bar fixing part (697) may be located between the upper surface (101) of the first chamber and the support frame (15). By forming the support space (15S), a predetermined guide space (not shown) between the upper surface (101) of the first chamber and the support frame (15) may be formed as the support frame (15) moves from the support space (15S) toward the side of the support frame. By placing the support guide part (692) in the guide space, the steam of the first chamber (100) may be prevented from escaping to the drive part (610). To this end, the upper surface of the support guide part (692) and the hanger bar support part (691) may be sealed. A predetermined guide space between the upper surface (101) of the first chamber and the support frame (15) may be maintained. Additionally, the support guide part (692) can guide the position of the hanger support part (691). This is because the hanger support part (691) can move in the vibration direction (+X, -X) inside the support guide part (692).

[0168] The above-mentioned hanger support member (691) may be positioned to penetrate the support guide member (692) vertically. Additionally, the length of the horizontal cross-section of the hanger support member (691) in the vibration direction (+X, -X) may be shorter than the length of the direction perpendicular to the vibration direction (+X, -X) (+Y, -Y).

[0169] The above driving unit (610) includes a motion conversion unit (680) connected to a hanger unit (690). In particular, the hanger bar (693) may include a slot (694) connected to the motion conversion unit (680). Additionally, the hanger bar (693) may include a slot cover (695) for protecting the slot.

[0170] When looking at an enlarged cross-section of the slot cover (695), the slot (694) can form a slit-shaped slot internal space (6941) that extends in a direction (+Y, -Y) across the vibration direction (+X, -X). Additionally, the motion conversion part (680) can be inserted into the slot (694) by protruding parallel to the central axis (Oc) to be described later, and positioned in the slot internal space (6941).

[0171] In this embodiment, the slot (694) forms a slit-shaped slot internal space (6941) extended in the directions (+Y, -Y), and the motion conversion unit (680) protrudes downward and is inserted into the slot (694). Referring to FIG. 10, the motion conversion unit (680) can be coupled to rotate integrally with the driving unit (610). That is, it is coupled to rotate integrally with the vibrating body (630) so that when the driving unit (610) vibrates, it vibrates together and moves back and forth, tracing an arc trajectory.

[0172] The motion conversion unit (680) may include a rotational projection (6811) protruding toward the first chamber (100) in a direction parallel to the central axis (Oc) from the vibrating body (630), a connecting projection (6813) inserted into the slot (694) in a direction parallel to the central axis (Oc) and located in the slot internal space (6941), and a connecting rod (6812) connecting the rotational projection (6811) and the connecting projection (6813). The connecting projection (6813) or the rotational projection (6811) may extend along a connecting axis (Oh) parallel to the central axis (Oc). Accordingly, one of the connecting projection or the rotational projection (6811) will be positioned on the connecting axis (Oh).

[0173] The slot (694) is formed in a long direction (+Y, -Y) that is orthogonal to the vibration direction (+X, -X) of the garment support (600). When the motion conversion unit (680) is inserted into the slot (694) and rotates about the central axis (Oc), the motion conversion unit (680) will move relative to the slot (694) in the orthogonal direction (+Y, -Y).

[0174] Accordingly, the hanger bar (693) will reciprocate in the vibration direction (+X, -X). In the enlarged cross-sectional view of FIG. 7, the direction in which the motion conversion unit (680) reciprocates (rotates) along an arc trajectory within a predetermined range while inserted into the slot (694) is indicated by an arrow. Accordingly, the range of movement of the slot (694) vibrating in the vibration direction or motion direction (+X, -X) is indicated by a dotted line.

[0175] FIG. 8 shows an example in which the driving unit (610) is combined. FIG. 9(a) shows the driving unit (610) with a support member (670) and a motion conversion unit (680). FIG. 9(b) shows a vibrating body (630).

[0176] Referring to FIGS. 8 and 9, the driving unit elastic member (635) may be configured to elastically deform or elastically restore when the driving unit (610) rotates around the central axis (Oc). The driving unit elastic member (635) may be configured to elastically deform or elastically restore when the vibrating body (630) rotates around the central axis (Oc).

[0177] The above-mentioned driving unit elastic member (635) can limit the driving unit (610) to vibrate within a predetermined angle range. Accordingly, the elastic force of the driving unit elastic member (635) and the centrifugal force of the first eccentric part (6341) and the second eccentric part (6342) can determine the vibration pattern (amplitude and frequency) of the above-mentioned unit (610). This is because it performs a second-order harmonic oscillation, which is roughly determined by the mass, spring, and damper.

[0178] The vibration pattern of the driving unit (610) can be determined by the amplitude of the driving unit (610) and the frequency of the driving unit (610). The frequency of the driving unit (610) refers to the number of reciprocating cycles in which the driving unit rotates in a first rotational direction from an initial position for a predetermined period of time, then rotates in a second rotational direction opposite to the first rotational direction, and then returns to the initial position. The units commonly used are the number of reciprocating cycles per second (Hz) or the number of reciprocating cycles per minute (RPM). The amplitude of the driving unit (610) may refer to a predetermined angle in which the driving unit (610) rotates.

[0179] The vibration pattern of the above-mentioned drive unit (610) is converted into the reciprocating motion of the hanger bar (693) by the motion conversion unit (680), and ultimately, the vibration pattern of the above-mentioned drive unit (610) will determine the amplitude and frequency of the above-mentioned hanger bar (693). The amplitude of the above-mentioned hanger bar (693) refers to the maximum distance from the initial position when the above-mentioned hanger bar (693) moves in the motion direction (+X, -X) from the initial position. The frequency of the above-mentioned hanger bar (693) refers to the number of reciprocating motions until the above-mentioned hanger bar (693) returns to the initial position after one reciprocating motion in the motion direction from the initial position for a predetermined period of time. Likewise, the unit may be reciprocating motions per second (Hz) or reciprocating motions per minute (RPM). Unless otherwise specified in this specification, RPM refers to the number of reciprocating cycles per minute of the hanger bar (693), and amplitude refers to the amplitude of the hanger bar (693).

[0180] In addition, the time taken for one round trip of the above hanger bar (693) can be expressed as a period, which can generally be expressed as the reciprocal of the frequency.

[0181] One end of the above-mentioned drive unit elastic member (635) may be fixed to the vibrating body (630) and the other end may be fixed to the support member (670). The above-mentioned drive unit elastic member (635) may include a spring, etc.

[0182] As described above, the driving unit (610) may include a motor (620) that generates rotational force, a vibrating body (630) that supports the motor (620) and vibrates alternately in a first rotational direction and a second rotational direction opposite to the first rotational direction by the rotation of the motor, and a motion conversion unit (680) that rotates in unison with the vibrating body (630) and is connected to the hanger bar (693) to convert the vibration of the vibrating body (630) so that the hanger bar (693) can reciprocate along a preset motion direction.

[0183] The above-mentioned vibrating body (630) may be connected to the support frame (15) by a support member (670). Additionally, the vibrating body (630) may form the outer shape of the driving unit (610). The above-mentioned vibrating body (630) may be provided to be rotatable relative to the support frame (15) around a central axis (Oc) set with respect to the motor rotation axis (625).

[0184] The support member (670) can rotatably support the vibration body (630). Additionally, the vibration body (630) may be provided to be rotatable only within a predetermined angle range. For example, the support frame (15) or the support member (670) may include a limiter (not shown) that can contact the vibration body (630) to limit the rotation range of the vibration body (630). Alternatively, without a separate limiter (not shown), the rotation range of the vibration body (630) may be limited by utilizing the fact that the elastic force of the driving elastic member (635) increases as the vibration body (630) rotates further.

[0185] The above-described vibrating body (630) may further include a first eccentric part (6341) connected to the motor (620) and having an eccentric weight rotating with respect to a first rotation axis (Ow1) parallel to the motor rotation axis (or center axis Oc), and a second eccentric part (6342) connected to the motor (620) and having an eccentric weight rotating with respect to a second rotation axis (Ow2) parallel to the motor rotation axis (625), located opposite to the first rotation axis (Ow1) along the width direction of the cabinet (10).

[0186] The above-mentioned vibrating body (630) rotatably supports the motor (620), the first eccentric part (6341), and the second eccentric part (6342), and the first eccentric part (6341) and the second eccentric part (6342) each rotate according to the rotation of the motor (620), thereby allowing the vibrating body (630) to alternately vibrate in a first rotational direction and a second rotational direction opposite to the first rotational direction.

[0187] The above vibration body (630) can support the motor (620). The vibration body (630) and the motion conversion unit (680) are coupled so as to rotate together as a single unit. The above vibration body (630) can support weight shafts (6381, 6382). In addition, the above vibration body (630) can support the first eccentric part (6341) and the second eccentric part (6342). The above vibration body (630) can accommodate the first eccentric part (6341) and the second eccentric part (6342) inside.

[0188] The above vibration body (630) may further include a vibration base (210) that supports the motor (620), the first eccentric part (6341), and the second eccentric part (6342), and a vibration case (631) that is coupled to the vibration base (210) to form a space that accommodates the first eccentric part (6341) and the second eccentric part (6342).

[0189] The above driving unit (610) may include a first eccentric part (6341) that rotates with an eccentric weight around a predetermined first rotation axis (Ow1) spaced apart from the central axis (Oc). The first eccentric part (6341) may rotate with an eccentric weight around the first rotation axis (Ow1). The driving unit (610) may include a second eccentric part (6342) that rotates with an eccentric weight around a predetermined second rotation axis (Ow2) spaced apart from the central axis (Oc). The second eccentric part (6342) may rotate with an eccentric weight around the second rotation axis (Ow2).

[0190] The first rotation axis (Ow1) and the second rotation axis (Ow2) may be the same or different from each other. The second rotation axis (Ow2) may be the same as or parallel to the first rotation axis (Ow1). FIGS. 8 and 9 illustrate an example in which the first rotation axis (Ow1) and the second rotation axis (Ow2) are parallel to each other.

[0191] Referring to FIGS. 9(a) and FIGS. 9(b), the driving unit (610) may include an elastic member locking part (636) to which one end of the driving unit elastic member (635) is engaged. When the driving unit (610) rotates around a central axis (Oc), the driving unit elastic member (635) will be elastically deformed by the elastic member locking part (636), or the restoring force of the driving unit elastic member (635) will be transmitted to the elastic member locking part (636). Accordingly, the elastic member locking part (636) may be located on the vibrating body (630).

[0192] The above elastic member locking portion (636) may include a first elastic member locking portion (6361) to which one end of the first elastic member (6351) is locked. The first elastic member locking portion (6361) may be formed on the upper side of the connecting arm (633). The elastic member locking portion (636) may further include a second elastic member locking portion (6362) to which one end of the second elastic member (6352) is locked. The second elastic member locking portion (not shown) is formed on the lower side of the vibration base (6313). The elastic member locking portion (636) may include a third elastic member locking portion (not shown) to which one end of the third elastic member (not shown) is locked. The third elastic member locking portion may be formed on the motion conversion portion (680).

[0196] The second elastic member (6352) may be positioned on the lower side of the driving unit (610). One end of the second elastic member (6352) may be engaged with the second elastic member catch portion (6362) of the driving unit (610), and the other end may be engaged with the second seating portion (6772) of the support member (670). The second elastic member (6352) may include a torsion spring positioned around a support base plate through hole (6711) located in the support base plate (671) facing the central axis portion (675).

[0197] The third elastic member (not shown) is positioned on the lower side of the support base plate (671). The third elastic member may be positioned between the support base plate (671) and the motion conversion unit (680). One end of the third elastic member may be engaged with the third locking part (not shown) of the driving unit (610), and the other end may be engaged with the third seating part (not shown) of the support member (670). The third elastic member (6352) may include a torsion spring positioned around the circumference of the rotational projection (6811).

[0198] The support member (670) may include a support base plate (671) positioned on the lower side of the vibrating body (630). The support base plate (671) may be formed in the shape of a horizontal plate. A support base plate through-hole (6711) is formed on the central axis (Oc) of the support base plate (671), and a rotational projection (6811) may be inserted and pass through the support base plate through-hole (6711). A bearing (B2) is positioned in the support base plate through-hole (6711) so that the rotational projection (6811) can be rotatably supported.

[0199] The above support member (670) may further include a support upper plate (672) positioned on the upper side of the vibrating body (630) and a support extension part (673) connecting the support upper plate (672) and the support base plate (671).

[0200] The above-mentioned support upper plate (672) may be formed in the shape of a horizontal plate. The support member (670) may include a central axis portion (675) protruding along the central axis (Oc) from the support upper plate (672). The central axis portion (675) may protrude downward from the lower side of the support upper plate (672). The lower end of the central axis portion (675) may be inserted into a rotational axis connection groove (6331) formed by penetrating the connecting box. The central axis portion (675) may rotatably support the vibrating body (630) through a bearing (B1).

[0201] The support extension (673) extends in the height direction of the cabinet and can combine the support upper plate (672) and the support base plate (671). A pair of support extensions (673) may be placed at both ends of the support upper plate (672).

The third mounting portion (not shown) may be located on the lower side of the support base plate (671).

[0203] The motion conversion unit (680) can be coupled to the vibration body (630) so as to rotate integrally with the vibration body. The motion conversion unit (680) can be connected to the hanger bar (693) at a position (Oh) spaced apart from the central axis (Oc) by a predetermined distance. The motion conversion unit (680) will transmit the vibration of the vibration body (630) to the hanger bar (693).

[0204] The motion conversion unit (680) will transmit the vibration of the vibration body (630) to the hanger bar (693) on the connecting shaft (Oh). The motion conversion unit (680) may include a rotational projection (6811) protruding along the connecting shaft (Oh). The rotational projection (6811) may protrude from the vibration body (630) toward the hanger bar (693) parallel to the center shaft (Oc).

[0205] One end of the above connecting projection (6813) can be inserted into the slot (694). Eventually, the motion conversion unit (680) will convert the vibrational motion of the driving unit (610) to cause the hanger bar (693) to reciprocate in a preset motion direction or vibration direction.

[0206] FIG. 10 shows the drive unit (610) in disassembly. As described above, the drive unit (610) may include the motor (620), a vibrating body (630) that supports the motor (620) and vibrates alternately in clockwise and counterclockwise directions by the rotation of the motor (620), and a motion conversion unit (680) that rotates in unison with the vibrating body (630) and is connected to the hanger bar (693) to convert the vibration of the vibrating body (630) so that the hanger bar (693) can reciprocate along a preset motion direction. The drive unit (610) may further include a drive unit elastic member (635) to vary the amplitude and frequency of the hanger bar (693) by utilizing the characteristics of harmonic excitation motion.

[0207] The above-described vibrating body (630) may further include a first eccentric part (6341) connected to the motor (620) and having an eccentric weight rotating with respect to a first rotation axis (Ow1) parallel to the motor rotation axis (or center axis Oc), and a second eccentric part (6342) connected to the motor (620) and having an eccentric weight rotating with respect to a second rotation axis (Ow2) parallel to the motor rotation axis (625), located opposite to the first rotation axis (Ow1) along the width direction of the cabinet (10).

[0208] The above-mentioned vibrating body (630) rotatably supports the motor (620), the first eccentric part (6341), and the second eccentric part (6342), and the first eccentric part (6341) and the second eccentric part (6342) each rotate according to the rotation of the motor (620), thereby allowing the vibrating body (630) to alternately vibrate in a first rotational direction and a second rotational direction opposite to the first rotational direction.

[0209] The first eccentric part (6341) can be supported by the vibrating body (630). The first eccentric part (6341) can be rotatably supported by a first weight shaft (6381) disposed in the vibrating body (630). The second eccentric part (6342) is supported by the vibrating body (630). The second eccentric part (6342) can be rotatably supported by a second weight shaft (6382) disposed in the vibrating body (630).

[0210] The center of gravity of the first eccentric part (6341) and the second eccentric part (6342) has a phase difference of 180 degrees (°) relative to each other, and the rotational direction of the first eccentric part (6341) and the second eccentric part (6342) will rotate in the same direction. That is, when the first eccentric part (6341) rotates in the first rotational direction, the second eccentric part (6342) also rotates in the first rotational direction, and when the first eccentric part (6341) rotates in the second rotational direction, which is the opposite direction of the first rotational direction, the second eccentric part (6342) also rotates in the second rotational direction. To this end, the vibration body (630) may further include a gear-shaped center transmission part (6453) according to the rotation of the motor, and a gear-shaped first transmission part (6451) and a second transmission part (6452) provided on both sides of the center transmission part (6453) to rotate the first eccentric part (6341) and the second eccentric part (6342) in the same direction.

[0211] Accordingly, the center of gravity of the first eccentric part (6341) and the second eccentric part (6342) has a phase difference of 180 degrees (°) relative to each other, and the rotational direction of the first eccentric part (6341) and the second eccentric part (6342) may be the same.

[0212] Since the central transmission unit (6453), the first transmission unit (6451), and the second transmission unit (6452) are meshed in a gear-like manner and rotate, the rotational direction of the first transmission unit (6451) and the second transmission unit (6452) will rotate in the same direction according to the rotational direction of the central transmission unit (6453).

[0213] Alternatively, the center transmission part (6453) and the first rotation part and the second rotation part (6372) may be directly connected in a gear or pulley form without the first transmission part (6451) and the second transmission part (6452).

The first weight member (6341a) may rotate integrally with the first rotating part (6371). The first weight member (6341a) may be formed of a material having a higher specific gravity than the first rotating part (6371). This is so that the first weight member (6341a) is positioned on one side centered on the first rotation axis (Ow1) to induce eccentricity of the weight of the first eccentric part (6341).

[0216] The first weight member (6341a) may be formed as a columnar shape with a semicircular base. The first weight member (6341a) may be positioned within an angle range of 180 degrees around the first rotation axis (Ow1) at any point during the rotation of the first eccentric part (6341).

[0217] The second eccentric part (6342) includes a second rotating part (6372) that rotates around a second rotation axis (Ow2) in contact with the rotation transmission part (645). The second rotating part (6372) can receive rotational force from the rotation transmission part (645), and this can be achieved through a gear-shaped second rotation ring gear (6372d) located on the outer surface of the second rotating part (6372) and configured to mesh with the second transmission part (6452). The second rotating part (6372) can be formed as a cylindrical shape centered on the second rotation axis (Ow2).

[0218] The second eccentric part (6342) includes a second weight member (6342a) fixed to the second rotating part (6372). The second weight member (6342a) rotates integrally with the second rotating part (6372).

This is so that the second weight member (6342a) is positioned on one side centered on the second rotation axis (Ow2) to induce eccentricity of the weight of the second eccentric part (6342).

[0219] The second weight member (6342a) may be formed as a columnar shape with a semicircular base. The second weight member (6342a) may be positioned within an angle range of 180 degrees around the second rotation axis (Ow2) at any point during the rotation of the second eccentric part (6342).

[0220] The first rotating part (6371) and the second rotating part (6372) may be formed to have the same weight to the extent that an error in the manufacturing process is allowed. Also, the first weight member (6341a) and the second weight member (6342a) may be formed to have the same weight.

The motor (52) may be provided with a motor rotation shaft (625) positioned on the central axis (Oc). The motor rotation shaft (625) will protrude downward and be connected to the rotation transmission part (645).

[0239] The above-mentioned rotating projection (6811) may be positioned to penetrate the support base plate (671) along the central axis (Oc). A bearing (B2) may be positioned between the above-mentioned rotating projection (6811) and the support base plate (671). Thus, the above-mentioned rotating projection (6811) may be rotatably supported by the support base plate (671). The above-mentioned rotating projection (6811) may transmit the rotational force of the above-mentioned vibrating body (630) to the hanger bar (693) through the connecting rod (6812) and the connecting projection (6813).

The connecting projection (6813) is inserted into the slot (694) to convert the vibration of the vibrating body (630) into the reciprocating motion of the hanger bar (693).

[0241] The motion direction or vibration direction (+X, -X) of the hanger bar (693) used in this specification refers to a direction in which the hanger bar (693) is set to reciprocate, and in this embodiment, an example is shown in which the left and right directions are the vibration directions (+X, -X).

[0242] Additionally, the 'central axis (Oc), first rotation axis (Ow1), second rotation axis (Ow2), and connecting axis (Oh)' mentioned throughout this description are fictitious axes for the purpose of describing this disclosure and do not refer to actual parts of the device.

[0243] The central axis (Oc) refers to a virtual straight line that serves as the center of rotation of the drive unit (610). The central axis (Oc) is a virtual straight line that maintains a fixed position relative to the frame (10). The central axis (Oc) may extend along the height direction of the cabinet (10).

[0244] To provide the function of the central axis (Oc), as in the present embodiment, a central axis portion (675) protruding along the central axis (Oc) is formed in the support member (670), and a support base plate through hole (6711) or through groove may be formed in the vibrating body (630) to rotatably engage the central axis portion (675). To provide the function of the central axis (Oc), as in another embodiment, a protrusion protruding along the central axis (Oc) is formed in the vibrating body (630), and a groove may be formed in the support member (670) to rotatably engage the protrusion.

[0245] The first rotation axis (Ow1) refers to an imaginary straight line that serves as the rotation center of the first eccentric part (6341). The first rotation axis (Ow1) maintains a fixed position relative to the vibrating body (630). That is, even if the vibrating body (630) moves, the first rotation axis (Ow1) moves integrally with the vibrating body (630) and maintains a relative position relative to the vibrating body (630). The first rotation axis (Ow1) may extend along the height direction of the cabinet (10).

[0246] To provide the function of the first rotation axis (Ow1), a first weight shaft (6381) disposed on the first rotation axis (Ow1) as in the present embodiment may be provided. To provide the function of the first rotation axis (Ow1), as in another embodiment, a projection protruding along the first rotation axis (Ow1) may be formed on either the first eccentric part (6341) or the vibrating body (630), and a groove may be formed on the other so as to rotatably engage with the projection.

[0247] The second rotation axis (Ow2) refers to an imaginary straight line that serves as the center of rotation of the second eccentric part (6342). The second rotation axis (Ow2) maintains a fixed position relative to the vibrating body (630).

The second rotation axis (Ow2) may extend along the height direction of the cabinet (10).

[0248] In order to provide the function of the second rotation axis (Ow2), a second weight shaft (6382) disposed on the second rotation axis (Ow2) as in the present embodiment may be provided, but in another embodiment, a projection protruding along the second rotation axis (Ow2) may be formed in either the second eccentric part (6342) or the vibrating body (630), and a groove formed in the other so as to be rotatably engaged with the projection may be formed.

[0249] The connecting axis (Oh) refers to an imaginary straight line spaced apart from the central axis (Oc). The connecting axis (Oh) is positioned parallel to the central axis (Oc). The connecting axis (Oh) maintains a fixed position relative to the vibrating body (630). That is, even if the vibrating body (630) moves, the connecting axis (Oh) moves integrally with the vibrating body (630) and maintains a relative position relative to the vibrating body (630). The connecting axis (Oh) can be extended in the vertical direction. A motion conversion unit (680) may be provided along the connecting axis (Oh) at the connection point between the driving unit (610) and the hanger bar (693) so that the alternating rotational motion (vibrational motion) of the driving unit (610) is converted into the linear reciprocating motion of the hanger bar (693).

[0250] The circumferential direction (Dl) refers to the periphery direction centered on the central axis (Oc) and encompasses the first rotation direction (Dl1) and the second rotation direction (Dl2) which is opposite to the first rotation direction. The first rotation direction (Dl1) and the second rotation direction (Dl2) are defined based on the state viewed from either direction (+Z) among the extension directions (+Z, -Z) of the central axis (Oc).

[0251] When the direction of the centrifugal force (F1) with respect to the first rotation axis (Ow1) due to the rotation of the first eccentric part (6341) becomes the circumferential direction (Dl), the centrifugal force (F1) will induce rotation about the central axis (Oc) of the vibrating body (630). Additionally, when the direction of the centrifugal force (F2) with respect to the second rotation axis (Ow2) due to the rotation of the second eccentric part (6342) becomes the circumferential direction (Dl), the centrifugal force (F2) will induce rotation about the central axis (Oc) of the vibrating body (630).

[0252] The radial direction (Dr) refers to the direction traversing the central axis (Oc) and encompasses the outer radial direction (Dr1) and the inner radial direction (Dr2). The outer radial direction (Dr1) refers to the direction away from the central axis (Oc), and the inner radial direction (Dr2) refers to the direction approaching the central axis (Oc).

[0253] When the direction of the centrifugal force (F1) with respect to the first rotation axis (Ow1) due to the rotation of the first eccentric part (6341) becomes the diameter direction (Dr), the centrifugal force (F1) does not induce rotation about the center axis (Oc) of the vibrating body (630). Additionally, when the direction of the centrifugal force (F2) with respect to the second rotation axis (Ow2) due to the rotation of the second eccentric part (6342) becomes the diameter direction (Dr), the centrifugal force (F2) will not induce rotation about the center axis (Oc) of the vibrating body (630).

[0254] FIGS. 11 to 14 show a simplified representation of the driving unit (610) to explain the harmonic excitation motion of the driving unit.

[0255] Referring to FIGS. 11 to 14, the center of gravity (m1) of the first eccentric part (6341), the center of gravity (m2) of the second eccentric part (6342), the radius of rotation (r1) of the first center of gravity (m1) with respect to the first rotation axis (Ow1), the radius of rotation (r2) of the center of gravity (m2) with respect to the second rotation axis (Ow2), the angular velocity (w) centered on the first rotation axis (Ow1) of the first eccentric part (6341), and the angular velocity (w) centered on the second rotation axis (Ow2) of the second eccentric part (6342), the distance (A1) between the center axis (Oc) and the first rotation axis (Ow1), the distance (A2) between the center axis (Oc) and the second rotation axis (Ow2), and the distance (B) between the center axis (Oc) and the connecting axis (Oh) are illustrated.

[0256] Additionally, referring to FIGS. 11 to 14, the direction of the centrifugal force (F1) of the first eccentric part (6341) with respect to the first rotation axis (Ow1) and the centrifugal force (F2) of the second eccentric part (6342) with respect to the second rotation axis (Ow2) is illustrated. The resultant force of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) will be the rotational force of the vibrating body (630). Furthermore, the excitation force (Fo) is expressed as an external force having a point of application on the connecting axis (Oh), taking into account the moment arm lengths (A1, A2, B) of the resultant force of the centrifugal force (F1) and the centrifugal force (F2).

[0257] The magnitude of the above centrifugal force (F1) is m1·r1·w 2 And, the magnitude of the centrifugal force (F2) is m2·r2·w 2 The centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) are applied to the vibrating body (630), and the points of application of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) are located on the first rotation axis (Ow1) and the second rotation axis (Ow2), respectively. And, since the first eccentric part (6341) and the second eccentric part (6342) are rotated at the same speed simultaneously by the rotation transmission part (645), the first eccentric part (6341) and the second eccentric part (6342) will rotate with the same angular speed w.

[0258] Referring to FIG. 11, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) are provided to reinforce each other when generating rotational force around the central axis (Oc) of the vibrating body (630). That is, when the weight of the first eccentric part (6341) is eccentrically distributed with respect to the first rotation axis (Ow1) in either the first rotation direction (D11) or the second rotation direction (D12) with respect to the central axis (Oc), the weight of the second eccentric part (6342) is provided to be eccentrically distributed with respect to the second rotation axis (Ow2) in either direction (D1).

[0259] When the first eccentric part (6341) generates centrifugal force with respect to the first rotation axis (Ow1) in either the first rotation direction (D11) or the second rotation direction (D12) with respect to the above central axis (Oc), the second eccentric part (6342) generates centrifugal force with respect to the second rotation axis (Ow2) in either the above direction (D1). In this case, since the moment (A1·F1+A2·F2) caused by the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) is equal to the moment (B·Fo) caused by the excitation force (Fo), the excitation force (Fo) will be (A1·F1+A2·F2) / B. Accordingly, according to the example of FIG. 11, the vibrating body (630) will rotate clockwise, and the motion conversion unit (680) will rotate clockwise in response.

[0260] Referring to FIG. 12, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) are directed in opposite directions with respect to the central axis (Oc) of the vibrating body (630), so that their sum becomes zero, and thus no rotational force is generated. This occurs when the weight of the first eccentric part (6341) is eccentrically positioned with respect to the first rotation axis (Ow1) in either the outer diameter direction (Dr1) or the inner diameter direction (Dr2) with respect to the central axis (Oc), and the weight of the second eccentric part (6342) is eccentrically positioned with respect to the second rotation axis (Ow2) in the opposite direction to the said direction (D2).

[0261] In this case, since the direction of action of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) are opposite to each other, the magnitude of the resultant force of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) becomes equal to the difference between the magnitude of the centrifugal force (F1) of the first eccentric part (6341) and the magnitude of the centrifugal force (F2) of the second eccentric part (6342). Accordingly, at least one of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) is offset by the other.

[0262] Accordingly, the driving unit (610) moves the hanger bar (693) through rotation, and the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) in the circumferential direction (Dl) that induces the rotation of the driving unit (610) are reinforced to generate vibration force in a predetermined vibration direction (+X, -X), while the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) in the radial direction (Dr) that does not induce the rotation of the driving unit (610) are offset from each other, thereby suppressing the generation of vibration in the vertical direction (+Y, -Y) of the hanger bar (693) in the vibration direction (+X, -X).

[0263] Preferably, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) may be configured to 'completely cancel each other out' when the rotational force of the vibrating body (630) is not generated. Here, 'complete cancellation' means a state in which the sum of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) becomes zero. Through this, unnecessary vibration generation in the vertical direction (+Y, -Y) of a predetermined vibration direction (+X, -X) can be minimized.

[0264] In order for the centrifugal force (F1) of the first eccentric part (6341) in the diameter direction (Dr) and the centrifugal force (F2) of the second eccentric part (6342) to completely cancel each other out, the scalar quantity m1·r1 and the scalar quantity m2·r2 may be provided equally.

[0265] In other words, the radius of rotation (r1) of the center of gravity of the first eccentric part (6341) with respect to the first axis of rotation (Ow1) and the radius of rotation (r2) of the center of gravity of the second eccentric part (6342) with respect to the second axis of rotation (Ow2) can be provided to be equal to each other. That is, it can be designed so that r1=r2. In addition, the weight (m1) of the first eccentric part (6341) and the weight (m2) of the second eccentric part (6342) can be provided to be equal to each other (m1=m2). Due to the two constraint conditions (r1=r2, m1=m2), the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) in the diameter direction (Dr) can be completely canceled out. Of course, even if the radius of rotation (r1) and the radius of rotation (r2) are different from each other and the weight (m1) and the weight (m2) are different from each other, the scalar quantities m1·r1 and m2·r2 are provided equally so that the centrifugal force (F1) of the first eccentric part (6341) in the diameter direction (Dr) and the centrifugal force (F2) of the second eccentric part (6342) are completely canceled out from each other.

[0266] The distance (A1) between the first rotation axis (Ow1) and the center axis (Oc) and the distance (A2) between the second rotation axis (Ow2) and the center axis (Oc) can be provided to be equal to each other. Through this, the ratio in which the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) contribute to the generation of the excitation force (Fo) is made equal to each other, thereby preventing the fatigue load from being concentrated in either the part supporting the first eccentric part (6341) or the part supporting the second eccentric part (6342).

[0267] The first rotation axis (Ow1) and the second rotation axis (Ow2) may be spaced apart from the central axis (Oc) in the same direction or in opposite directions. The central axis (Oc), the first rotation axis (Ow1), and the second rotation axis (Ow2) may be arranged to intersect perpendicularly with a single imaginary straight line. In the embodiment disclosed through FIGS. 4 to 10, the first rotation axis (Ow1) and the second rotation axis (Ow2) are each spaced apart from the central axis (Oc) in opposite directions.

[0268] Through this, the centrifugal force (F1) of the first eccentric part (6341) in the diameter direction (Dr) and the centrifugal force (F2) of the second eccentric part (6342) can be offset.

[0269] The angular velocity (w) centered on the first rotation axis (Ow1) of the first eccentric part (6341) and the angular velocity (w) centered on the second rotation axis (Ow2) of the second eccentric part (6342) can be set to be the same as each other. Through this, it will be possible to reinforce and offset the periodic centrifugal force (F1, F2) resulting from the rotation of the first eccentric part (6341) and the second eccentric part (56, 356).

[0270] Here, angular speed refers to a scalar that has only magnitude and no direction of rotation, and can be used to distinguish it from angular velocity, which is a vector that has both a direction of rotation and magnitude. That is, the fact that the angular speed (w) of the first eccentric part (6341) and the angular speed (w) of the second eccentric part (6342) are the same does not imply that their directions of rotation are the same.

[0271] Referring to FIGS. 11 to 14, the rotational direction around the first rotation axis (Ow1) of the first eccentric part (55) and the rotational direction around the second rotation axis (Ow2) of the second eccentric part (56) will be the same. The motion conversion part (680) is fixed to the vibrating body (630) and can rotate integrally with the vibrating body (630).

[0272] The first rotation axis (Ow1) and the second rotation axis (Ow2) are spaced apart from each other in opposite directions from the center axis (Oc). Additionally, the first rotation axis (Ow1) and the second rotation axis (Ow2) may be arranged symmetrically with respect to the center axis (Oc). Through this, it is possible to prevent the vibrating body (630) from being eccentrically deviated to one side with respect to the center axis (Oc) by the weight (m1, m2) of the first and second eccentric parts (6341, 6342).

[0273] Referring to FIGS. 11 to 14, when the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) cancel each other out, the direction of action of the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) is either the outer diameter direction (Dr1) or the inner diameter direction (Dr2).

[0274] FIGS. 11 to 14 show the state of each moment when the first eccentric part (55) and the second eccentric part (56), which are rotating with the same angular velocity (w), have rotated 90 degrees.

[0275] Referring to FIG. 11, when the first eccentric part (55) generates the centrifugal force (F1) of the first eccentric part (6341) with respect to the first rotation axis (Ow1) in the first rotation direction (Dl1), the second eccentric part (56) generates the centrifugal force (F2) of the second eccentric part (6342) with respect to the second rotation axis (Ow2) in the first rotation direction (Dl1). Accordingly, the centrifugal force (F1) and the centrifugal force (F2) of the second eccentric part (6342) reinforce each other to generate the rotational force of the first rotation direction (Dl1) of the vibrating body (630). The excitation force (Fo) transmitted to the hanger bar (693) on the connecting shaft (Oh) will act in the first rotation direction (Dl1).

[0276] Referring to FIG. 12, when the first eccentric part (55) generates the centrifugal force (F1) of the first eccentric part (6341) with respect to the first rotation axis (Ow1) in the inner diameter direction (Dr2), the second eccentric part (56) generates the centrifugal force with respect to the second rotation axis (Ow2) in the inner diameter direction (Dr2). Accordingly, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) do not generate rotational force of the vibrating body (630). The excitation force (Fo) transmitted to the hanger bar (693) on the connecting shaft (Oh) becomes zero. Furthermore, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) will act in opposite directions and cancel each other out.

[0277] Referring to FIG. 13, when the first eccentric part (55) generates the centrifugal force (F1) of the first eccentric part (6341) with respect to the first rotation axis (Ow1) in the second rotation direction (Dl2), the second eccentric part (56) generates the centrifugal force (F2) of the second eccentric part (6342) with respect to the second rotation axis (Ow2) in the second rotation direction (Dl2). Accordingly, the centrifugal force (F1) and the centrifugal force (F2) of the second eccentric part (6342) reinforce each other to generate the rotational force of the vibrating body (630) in the second rotation direction (Dl2). The excitation force (Fo) transmitted to the hanger bar (693) on the connecting shaft (Oh) will act in the second rotation direction (Dl2).

[0278] Referring to FIG. 14, when the first eccentric part (55) generates the centrifugal force (F1) of the first eccentric part (6341) with respect to the first rotation axis (Ow1) in the outer diameter direction (Dr1), the second eccentric part (56) generates the centrifugal force with respect to the second rotation axis (Ow2) in the outer diameter direction (Dr1). Accordingly, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) do not generate rotational force of the vibrating body (630). The excitation force (Fo) transmitted to the hanger bar (693) on the connecting shaft (Oh) becomes zero. Furthermore, the centrifugal force (F1) of the first eccentric part (6341) and the centrifugal force (F2) of the second eccentric part (6342) will act in opposite directions and cancel each other out.

[0279] Accordingly, referring to FIGS. 11 to 14, when the motor (620) rotates clockwise or counterclockwise, the vibrating body (630) will alternately rotate in a first rotational direction and a second rotational direction opposite to the first rotational direction, depending on the position of the weight of the first eccentric part (6341) and the second eccentric part (6342).

[0280] The alternating rotational motion of the above-mentioned vibrating body (630) becomes a reciprocating motion following a constant arc trajectory of the motion conversion unit (680), and the reciprocating motion of the above-mentioned motion conversion unit (680) can eventually be converted into a reciprocating motion along the preset motion direction or vibration direction of the above-mentioned hanger bar (693) by the slot (694).

[0281] FIG. 15(a) illustrates a graph of the amplitude of the hanger bar (693) with respect to the frequency, which can be obtained through a physical analysis of the harmonic excitation motion of the driving unit (610). Since the reciprocating motion of the driving unit (610) ultimately manifests as reciprocating motion through the hanger bar (693), this can be considered as a graph of the frequency and amplitude of the hanger bar (693).

[0282] If the weights (m1, m2) of the first eccentric part (6341) and the second eccentric part (6342) are at any position, the harmonic excitation motion of the driving part (610) will be a second-order differential equation as shown in Equation 1 below.

[0283] [Mathematical Formula 1]

[0284]

[0285] Here, p1, p2, and p3 are non-zero constants. p1 is the mass of the garment support (600) excluding the support member (670) fixed to the support frame (15). p2, representing the damping coefficient, may be generated by structural factors of the garment support (600) and / or by the garment hanging on the hanger bar (693). p3, representing the elasticity coefficient, is generated by the driving elastic member (635). And x is the position of the connecting axis (Oh) in the direction of motion (+X, -X) according to time (t). The excitation force Fo is m·r·w if the weight of the first eccentric part (6341) and the second eccentric part (6342) and the distance to the center axis are the same. 2 It can be expressed as follows. Here, w represents the angular velocity, m represents the mass of each eccentric part, and r represents the distance from each eccentric part to the central axis.

[0286] When the above mathematical formula is solved, the natural frequency (resonant frequency or resonant frequency) of the driving unit can be expressed by the following mathematical formula 2.

[0287] [Mathematical Formula 2]

[0288]

[0289] Here, ω n represents the natural frequency (or resonance frequency).

[0290] And, if the following mathematical equation 3 is satisfied, it will have a maximum amplitude near the natural frequency. This is because if the above mathematical equation 3 is not satisfied, the amplitude simply decreases monotonically as the frequency increases, so the amplitude cannot vary with frequency, which is undesirable.

[0291] [Mathematical Formula 3]

[0292]

[0293] Here, the larger the value of p2, the larger the amplitude can be. (where p2 is positive)

[0294] By using the above mathematical formulas 1 to 3, the amplitude of the hanger bar (693) according to the vibration frequency (or reciprocating cycles per minute RPM) of the hanger bar (693) (the unit is an arbitrary unit AU as it represents only relative size) can be obtained, and the shape of the graph as shown in FIG. 15(a) can be obtained.

[0295] Through the above graph, various modes of the hanger bar (693) can be set according to frequency and amplitude. Here, a mode refers to the hanger bar (693) reciprocating in a preset direction of motion or vibration direction with a predetermined frequency and amplitude.

[0296] If the shape of the graph is monotonically decreasing, unlike the graph in FIG. 15(a), the amplitude may not change much with frequency. Therefore, as illustrated in the example in FIG. 15(a), it may be difficult to distinguish different modes in four regions. Therefore, to obtain a graph shape like that of FIG. 15(a), the condition of Equation 3 above must be satisfied.

[0297] In FIG. 15(a), four regions in which four different modes can be set are labeled A, B, C, and D, respectively. B can be set near the natural frequency (resonant frequency, or resonant frequency). Therefore, in region B, the hanger bar (693) can have a maximum amplitude. When the hanger bar (693) reciprocates with the frequency and amplitude set in region B, it can be said that the hanger bar (693) reciprocates in B mode.

[0298] When the hanger bar reciprocates with a selected frequency and amplitude in region A, it can be said that the hanger bar (693) reciprocates in A mode. Likewise, when the hanger bar reciprocates with a selected frequency and amplitude in regions C and D, respectively, it can be defined that the hanger bar (693) reciprocates in C mode and D mode, respectively.

[0299] The frequency and amplitude of the hanger bar (693) may be independent of each other. However, in the present disclosure, the amplitude of the hanger bar (693) may be determined according to the frequency of the hanger bar (693) due to harmonic excitation motion. This is because, in the vibration motion of the driving unit (610), the rotation angle rotating in the first rotation direction and the second rotation direction due to harmonic excitation motion varies according to the frequency of the driving unit (610).

[0300] That is, in the garment processing device of the present disclosure, when the hanger bar (693) reciprocates, the amplitude of the hanger bar (693) may vary by the period of the hanger bar (693) or the frequency of the hanger bar corresponding to the period of the hanger bar. That is, the amplitude of the hanger bar (693) may be determined by the frequency of the hanger bar (693).

[0301] FIGS. 15(b) to 15(e) show the change in amplitude over time when the hanger bar (693) moves in A mode, B mode, C mode, and D mode, respectively. Due to the nature of harmonic excitation motion, the amplitude takes the form of a sinusoidal wave.

[0302] The frequency and amplitude of the hanger bar (693) can be defined as follows. The frequency of the hanger bar (693) is the reciprocal of the time taken for the hanger bar (693) to move left and right once from the initial position and return to the initial position. That is, it is the reciprocal of the time taken (representing the cycle) to return from the initial position to the initial position after one reciprocating motion. In particular, in this specification, RPM, which represents the number of reciprocating cycles per minute, is used as the unit to represent the frequency of the hanger bar (693) rather than Hz.

[0303] The amplitude of the hanger bar (693) refers to the maximum distance the hanger bar can move when moving left and right from its initial position. The initial position refers to the position of the hanger bar (693) when it is initially at rest. Here, the magnitude of the amplitude is not an absolute value and can vary depending on the mass of the drive unit (610), so it is expressed as a relative value without units (or using an arbitrary unit, AU).

[0304] Referring to FIGS. 15(a) to 15(e), the frequency in mode A can be set to a value smaller than the resonant frequency of the driving unit (610), and the frequency in mode C can be set to a value larger than the resonant frequency.

[0305] The frequency and amplitude in mode A can also be referred to as the first frequency and first amplitude. And mode A can be referred to as the first mode. Likewise, the frequency and amplitude in mode C can also be referred to as the second frequency and second amplitude. And mode C can be referred to as the second mode.

[0306] Based on the resonance frequency of the drive unit (610), the first frequency may be set to be smaller than the resonance frequency, and the second frequency may be set to be larger than the resonance frequency. That is, the hanger bar (693) may reciprocate in one of the following modes: a first mode in which the hanger bar (693) is reciprocated with a preset first frequency smaller than the resonance frequency of the drive unit (610) and a first amplitude corresponding to the first frequency, and a second mode in which the hanger bar (693) is reciprocated with a preset second frequency larger than the resonance frequency and a second amplitude corresponding to the second frequency.

[0307] Referring to FIG. 15(a), the first frequency is smaller than the second frequency, but the first amplitude and the second amplitude are similar, or the first amplitude may be slightly larger than the second amplitude.

[0308] The frequency and amplitude in mode B can also be referred to as the third frequency and third amplitude. And mode B can be referred to as the third mode. Likewise, the frequency and amplitude in mode D can also be referred to as the fourth frequency and fourth amplitude. And mode D can be referred to as the fourth mode.

[0309] The third frequency may be set near the resonance frequency where resonance or resonance may occur. Since unexpected shaking or vibration may occur at the resonance frequency, the third frequency may be pre-set to any frequency near the resonance frequency to avoid this. Accordingly, the hanger bar (693) may reciprocate in any one of the first mode, the second mode, and a third mode in which the hanger bar (693) is reciprocated at a third frequency located between the first frequency and the second frequency, and a third amplitude corresponding to the third frequency. Also, the third amplitude may be larger than the first amplitude and the second amplitude.

[0310] The fourth frequency can be set at a frequency greater than the second frequency. That is, the hanger bar (693) reciprocates in any one of the first mode, the second mode, the third mode, and a fourth mode in which the hanger bar is reciprocated at a predetermined fourth frequency greater than the third frequency and a fourth amplitude corresponding to the fourth frequency, and the fourth amplitude may be smaller than the first amplitude, the second amplitude, and the third amplitude.

[0311] In order to make the amplitude change significantly with frequency as above, it must have a pattern of harmonic excitation motion that has a maximum value at the resonance frequency as shown in Fig. 15(a).

[0312] Alternatively, the frequency and amplitude of the driving unit may be determined independently of each other. In this regard, as shown in FIG. 3, the amplitude and frequency can be changed independently by changing the rotation angle of the driving unit. However, since the clothing processing device (1000) is intended for the management of clothing, it is sufficient to implement only the amplitude and frequency required to perform various functions necessary for clothing management, such as dusting, drying, and wrinkle removal functions, so there is no need to implement the driving unit to independently change the amplitude and frequency.

[0313] Table 1 below schematically illustrates the relationship between various functions required for clothing care and amplitude and frequency. Specifically, it shows the relationship between amplitude and frequency for dusting, drying, and wrinkle removal functions. In Table 1, each function is distinguished, and the more shapes representing each performance, the higher the corresponding performance level.

[0314] [Table 1]

[0315]

[0316] Referring to Table 1, it can be seen that as the vibration frequency (RPM) of the hanger bar (693) increases, the dust removal function improves. Conversely, as the vibration frequency (RPM) of the hanger bar (693) decreases, the drying function improves. Also, it can be seen that the wrinkle removal function improves as the amplitude increases. However, it can be seen that when the vibration frequency of the hanger bar (693) and the amplitude of the hanger bar (693) decrease, the dust removal and drying performance effects are weak. Therefore, modes with small amplitude or low vibration frequency may not be used except in special cases.

[0317] Specifically, the higher the frequency (RPM) of the hanger bar (693), the better the dust removal performance can be. This is because the faster the hanger bar (693) reciprocates, the more dust can fall off the clothing due to inertia. However, even if the frequency is high, it may not be suitable for dust removal if the amplitude is small. This is because when the amplitude is small, inertia does not act enough to cause the dust to fall off.

[0318] In contrast, the lower the frequency (RPM) of the hanger bar (693), the better the drying function. However, since the garment processing device (1000) of the present disclosure is a drying method using a heat pump rather than dehydration by centrifugal force, high-temperature dry air must flow between multiple garments mounted on the garment support (600). Therefore, if the frequency (RPM) of the hanger bar (693) is high, the air flow may actually be hindered. However, if the amplitude is too small, it is the same as simply standing still, so the air flow may not be promoted.

[0319] In addition, the larger the amplitude of the hanger bar (693), the more advantageous it is for wrinkle removal. This is because a larger amplitude of the hanger bar (693) has the effect of straightening the clothes, thus making it effective for smoothing out wrinkles. Furthermore, when the clothing forms a waveform due to the amplitude of the hanger bar (693), nodes may be created due to the standing wave. Since the nodes do not change in a certain mode, wrinkles may not be removed from the clothing in the area corresponding to the nodes. Therefore, it is necessary to change the nodes, and to do this, it would be desirable to change the mode of the hanger bar (693) while performing the wrinkle removal function.

[0320] Referring to Table 1 and FIG. 15(a), it can be explained which of the various modes that can be implemented in the drive unit (610) can be specialized for which clothing care function. This is illustrated in FIG. 16.

[0321] Mode A (first mode), Mode C (second mode), and Mode B (third mode) that can be implemented in the garment processing device of the present disclosure are indicated as A, B, and C, respectively, in FIG. 16, taking into account their respective relative frequencies and relative amplitudes. Mode D (fourth mode) is indicated separately, considering that it is used in special cases.

[0322] Comparing with FIG. 15, it can be seen that Mode A (the first mode) is a mode specialized for the drying function of clothes. That is, when the hanger bar (693) reciprocates at the first vibration frequency, it can appropriately shake the clothes mounted on the hanger bar (693). In particular, since steam penetrates the clothes through the steam unit (250) and the wet clothes are heavy, if the clothes are shaken more vigorously than the first vibration frequency, the fabric may be damaged due to friction between the hanger (H1, see FIG. 1) and the clothes (T, see FIG. 1). Therefore, among the aforementioned multiple modes, the first vibration frequency is the lowest, so it is desirable to use it. In addition, because the vibration frequency is low, clothes can be managed in a low-noise mode even late at night or early in the morning.

[0323] Mode B (the third mode) is a mode specialized for wrinkle removal, and the amplitude of the hanger bar (693) is the largest compared to other modes. Therefore, since it can cause the most shaking of the clothing, it will be easier to smooth out large wrinkles in the clothing.

[0324] Mode C (the second mode) is a mode specialized for dusting. Although the amplitude is similar to that of Mode A, the frequency is higher than that of Mode A. Therefore, while Mode A is specialized for drying due to its relatively lower frequency, Mode C can be more effective for dusting due to its relatively higher frequency. Additionally, although the second amplitude in Mode C is smaller than the third amplitude in Mode B, the hanger bar (693) can be reciprocated with a second frequency that is larger than the third frequency and has a certain amplitude, making it more advantageous than Mode A for wrinkle removal.

[0325] In other words, Mode C is specialized for dusting, but it is also effective for wrinkle removal. Additionally, Mode C can enhance the volume of garments such as padded jackets. By beating the filling to enlarge the air gaps between the fibers, it creates the effect of increasing the garment's volume. Essentially, it is a mode that increases the thickness of the clothing.

[0326] Here, dust refers to foreign substances that are very small and light, floating in the air or settling on objects and accumulating, eventually adhering to clothing. Therefore, dust may include lint, dead skin cells, animal hair, and soil dust. Generally, it has a size of 10 µm or larger. Dust smaller than this is referred to as fine dust.

[0327] Mode D (4th mode), which has the smallest amplitude and the largest frequency, can be used for a special purpose. That is, by transmitting fine vibrations with a large frequency and small amplitude to the clothing, it can act as an accelerator to facilitate the penetration of moisture between the fabrics of the clothing when or after steam is sprayed from the steam unit (250). This is because the more steam penetrates or permeates the clothing, the greater the moisture content of the clothing becomes, making it more effective for wrinkle removal and deodorizing performance. Additionally, Mode D can be effective for revitalizing fur in clothing made of fur. Since individual hairs are small unlike fabric, the frequency must be high to transmit vibrations to each individual hair to shake it and revitalize it.

[0328] In addition, the aforementioned D mode can be effective in removing fine dust particles smaller than general foreign substances or dust due to its high vibration frequency. This is based on a principle similar to that of a sonicator, which uses ultrasound to remove fine dust.

[0329] The functions of the above A mode (1st mode), above B mode (3rd mode), above C mode (2nd mode), and above D mode (4th mode) are summarized as shown in Table 2 below.

[0330] [Table 2]

[0331]

[0332] Figure 17 schematically illustrates the vibration waveforms of the garment according to the four aforementioned modes. The first and second amplitudes, which are the amplitudes of modes A and C, are similar in magnitude, while the fourth amplitude, which is the amplitude of mode D, is relatively the smallest. Additionally, the third amplitude, which is the amplitude of mode B, is relatively the largest.

[0333] FIG. 17 illustrates a partial view of a hanger (H1) with clothing hanging on a hanger bar (693) in each mode. The double arrow indicates the direction of movement of the hanger bar (693). In each mode, when the hanger bar (693) moves back and forth according to a preset amplitude and frequency, the hanging clothing will also form a wave shape accordingly. That is, when one end of the clothing (T) is held and shaken, the wave travels along the clothing. At this time, the other end of the clothing will be the free end, and since the wave is reflected from the free end, it creates a standing wave, and thus a node can be formed. Therefore, referring to FIG. 18(d), multiple nodes can be formed on the clothing depending on the size of the wave, that is, the wavelength.

[0334] Since the change in amplitude of the garment at the above node is zero, it may not be suitable for wrinkle removal or dusting. Therefore, it is desirable to change the above node, and to this end, it may be desirable to use a combination of multiple modes rather than using only one mode to perform wrinkle removal, dusting, drying functions, etc.

[0335] FIGS. 18 and 19 illustrate an embodiment in which various clothing care functions are performed by combining the aforementioned modes. FIGS. 18 and 19 use a combination of various modes, which is referred to as motion. That is, motion refers to the repeated execution of a combination of modes consisting of at least one of a plurality of modes to perform clothing care functions for a predetermined motion time. That is, each mode implemented during the motion time can be repeated for a set time. For example, if a first mode is executed for 30 seconds for a first motion, followed by a second mode being executed for 5 minutes, the hanger bar (693) can alternately reciprocate the first mode for 30 seconds and the second mode for 5 minutes for a total wrinkle removal time of 1 hour.

[0336] The first mode and the second mode may be connected continuously, or they may be connected intermittently with a paused duration.

[0337] A single mode of motion may be sustained during the motion time, which is referred to as single-mode motion. In contrast, various modes may be combined and alternately repeated during the motion time, which is referred to as complex-mode motion. In the complex-mode motion, each mode may be performed repeatedly in sequence during the motion time for a set period.

[0338] In addition, a combination of these motions performed for a predetermined course time can be defined as a course.

[0339] Therefore, the above course time will be set to be longer than the above motion time. The above motion time will be set to be longer than the time set for each of at least one mode required to perform the garment care function.

[0340] Referring to FIGS. 18 and 19, the hanger bar (693) can reciprocate by including at least the third mode (mode B) during reciprocating motion. This is because the third mode (mode B) is the most basic mode for implementing motion.

[0341] FIGS. 18(a) to 18(c) illustrate examples of different wrinkle removal motions for removing wrinkles from clothing mounted inside the first chamber (100).

[0342] Referring to FIGS. 18(a) to 18(c), all three different wrinkle removal motions may include at least a B mode (third mode) specialized for wrinkle removal. That is, to remove wrinkles from a garment mounted in the first chamber (100), the hanger bar (693) may reciprocate in the third mode for at least a portion of the preset total wrinkle removal time.

[0343] Here, total wrinkle removal time refers to the total time required to perform the wrinkle removal motion.

[0344] It may be a single-mode motion in which only the third mode is performed during the total wrinkle removal time, or the third mode may be performed only during a portion of the total wrinkle removal time. FIGS. 18(a) to 18(c) illustrate different embodiments in which the third mode is executed only during a portion of the wrinkle removal time.

[0345] FIG. 18(a) illustrates an embodiment of a wrinkle removal motion. The hanger bar (693) may reciprocate in the first mode during a preset first wrinkle removal time (TW1), and then, when the first wrinkle removal time (TW1) has elapsed, may reciprocate in the third mode during a preset second wrinkle removal time (TW2). Furthermore, the hanger bar (693) may repeatedly reciprocate in the first mode during the first wrinkle removal time (TW1) and the third mode during the second wrinkle removal time (TW2) during the total wrinkle removal time. That is, FIG. 18(a) only illustrates the mode patterns of the first mode and the third mode that are continuously repeated during the total wrinkle removal time. FIG. 18 and FIG. 19 also only illustrate the patterns of repeated mode combinations unless otherwise specified.

[0346] FIG. 18(b) illustrates another embodiment of wrinkle removal. The hanger bar (693) may reciprocate in the third mode for a preset first wrinkle removal time (TW1'), and then, when the first wrinkle removal time (TW1') has elapsed, may reciprocate in the second mode for a preset second wrinkle removal time (TW2'). Additionally, the hanger bar (693) may repeatedly reciprocate in the third mode during the first wrinkle removal time (TW1') and the second mode during the second wrinkle removal time (TW2') during a preset total wrinkle removal time.

[0347] FIG. 18(c) illustrates another embodiment of wrinkle removal. A hanger bar (693) may reciprocate in the second mode for a preset first wrinkle removal time (TW1”), and then, when the first wrinkle removal time (TW1”) has elapsed, reciprocate in the fourth mode for a preset second wrinkle removal time (TW2”). Additionally, when the second wrinkle removal time (TW2”) has elapsed, reciprocate in the third mode for a preset third wrinkle removal time (TW3”). Furthermore, the hanger bar (693) may repeatedly reciprocate in the second mode for the first wrinkle removal time (TW1”), the fourth mode for the second wrinkle removal time (TW2”), and the third mode for the third wrinkle removal time (TW3”) during a preset total wrinkle removal time.

[0348] In another embodiment of the above volume motion, instead of repeating the second mode, the fourth mode, and the third mode, the hanger bar (693) may perform each mode only once during the total volume time. That is, the total wrinkle removal time may be divided into three times such that the sum of the first wrinkle removal time (TW1), the second wrinkle removal time (TW2), and the third wrinkle removal time (TW3) equals the total wrinkle removal time, and the second mode, the fourth mode, and the third mode may be performed respectively.

[0349] Therefore, in this case, the second mode, the fourth mode, and the third mode are each performed once, and the sum of the first wrinkle removal time (TW1), the second wrinkle removal time (TW2), and the third wrinkle removal time (TW3) will be the total wrinkle removal time.

[0350] The wrinkle removal motion shown in FIG. 18(a) can be referred to as the first wrinkle removal motion, the wrinkle removal motion shown in FIG. 18(b) as the second wrinkle removal motion, and the wrinkle removal motion shown in FIG. 18(c) as the third wrinkle removal motion.

[0351] The above-mentioned first wrinkle removal motion can be used to remove wrinkles from thin clothing, such as shirts. The above-mentioned first wrinkle removal motion necessarily uses Mode B, which is the third mode.

[0352] The first wrinkle removal motion described above is a motion that alternates between mode B and mode A. If the clothing is thin and light, applying a mode that is too strong may actually cause wrinkles. Therefore, the hanger bar (693) can be reciprocated by using mode B as the base and combining it with mode A. By applying both modes together, the position of the knots formed in the clothing can be changed as described above, so wrinkles on the clothing can be removed evenly.

[0353] The above second wrinkle motion can be used on thick and heavy clothing such as suits or school uniforms. To remove wrinkles from thick and heavy clothing, Mode B alone is insufficient, so Mode B and Mode C can be used in combination. Likewise, by applying the two modes together, the position of the knots formed in the clothing can be changed as described above, so wrinkles on the clothing can be removed evenly.

[0354] The above third wrinkle motion is intended to remove wrinkles from clothing thicker than a suit. To this end, the wrinkle removal effect can be maximized by using a combination of Mode B, Mode C, and Mode D.

[0355] That is, depending on the material and thickness of the clothing, one of the first wrinkle motion, the second wrinkle motion, and the third wrinkle motion can be selectively used, and the user can select the motion according to the material and thickness of the clothing. For example, an input / output unit (950) that receives the user's selection and outputs the current operating status of the clothing processing device (1000) can be located on the opposite side of the inner surface of the door (401), that is, on the front of the door (not shown) facing forward when the input port (11) is closed with the door (400). After the user places the clothing in the first chamber (100) and closes the door (400), if the user selects a desired menu according to the thickness, type, or material of the clothing through the input / output unit (950), the control unit (270) can reciprocate the hanger bar (693) through any one of the first wrinkle motion, the second wrinkle motion, and the third wrinkle motion.

[0356] FIG. 18(c) can be used to explain other motions. That is, in other motions, the combination of the second mode, the fourth mode, and the third mode is used repeatedly in the same way, but the execution time of each mode may be set differently. For example, as shown in FIG. 18(c), the pre-set first wrinkle removal time (TW1”), the pre-set first dust removal time (TM1), and the pre-set first volume time (TV1) are displayed together, but this is displayed only because the order of the modes is the same, and does not mean that they are the same time. The first wrinkle removal time (TW1”), the first dust removal time (TM1), and the first volume time (TV1) will be set to different time values ​​depending on each motion.

[0357] In order to remove dust and fine dust, including foreign substances attached to the clothing, the clothes must be shaken, so the reciprocating motion of the hanger bar may be necessary.

[0358] After removing large dust particles using Mode C (Mode 2), fine dust attached to clothing can be brushed off using Mode D (Mode 4), which has the highest acceleration due to its high frequency and small amplitude. Mode B (Mode 3) can be used to remove easily detachable foreign substances.

[0359] First, for the dust removal motion, the hanger bar (693) can reciprocate in the second mode for at least a portion of the total dust removal time, which is preset, in order to remove dust attached to the clothing mounted in the first chamber.

[0360] Here, total dust removal time refers to the total time required to perform the dust removal motion.

[0361] Additionally, the third mode may be included in all motions by default. Accordingly, the hanger bar (693) may reciprocate in the second mode for a preset first dust removal time (TM1), and then, when the first dust removal time (TM1) has elapsed, reciprocate in the fourth mode for a preset second dust removal time (TM2). Then, when the second dust removal time (TM2) has elapsed, reciprocate in the third mode for a preset third dust removal time (TM3). Accordingly, the hanger bar may repeatedly reciprocate in the second mode during the first dust removal time (TM1), the fourth mode during the second dust removal time (TM2), and the third mode during the third dust removal time (TM3) during a preset total dust removal time.

[0362] In another embodiment of the dust removal motion described above, the second mode, the fourth mode, and the third mode may not be repeated, but may each be performed only once. That is, the total dust removal time may be divided into three times such that the sum of the first dust removal time (TM1), the second dust removal time (TM2), and the third dust removal time (TM3) equals the total dust removal time, and the second mode, the fourth mode, and the third mode may be performed respectively.

[0363] Therefore, in this case, the second mode, the fourth mode, and the third mode are each performed once, and the sum of the first dust removal time (TM1), the second dust removal time (TM2), and the third dust removal time (TM3) will be the total volume time.

[0364] The clothing processing device (1000) further includes a dust sensor unit (911) located in the first chamber (100) and detecting the dust concentration inside the first chamber (100), and the first dust removal time can be changed according to the value of the dust concentration detected by the dust sensor unit (911).

[0365] The dust sensor unit (911) sends a control signal measuring the concentration of dust or fine dust to the control unit (270), and the control unit (270) can determine the current concentration of dust or fine dust based on this.

[0366] Through this, the control unit (270) can change the total dust removal time or the first dust removal time according to the value of the dust concentration detected by the dust sensor unit (911). Therefore, dust can be removed more efficiently in terms of energy.

[0367] Referring to FIG. 1, the dust sensor unit (911) may be provided on the inner surface of the first chamber (100), specifically on the rear surface of the first chamber (100). Alternatively, the dust sensor unit (911) may be located elsewhere, for example, near the air intake port (115) or inside the inlet duct (221).

[0368] Fig. 18(c) can also be used to explain a motion for a function that enhances the volume of clothing, such as padded clothing containing filling material.

[0369] As the garment contains filling material inside, such as padding, air contained in the gaps between the filling materials may escape depending on use and storage. In this case, the volume of the padding will decrease, and the thermal insulation performance will also decline. The aforementioned volume can be expressed as the thickness of the garment, and preserving the volume ultimately means increasing the thickness of the garment beyond the thickness before the volume motion is performed through a volume motion in the garment processing device (1000).

[0370] To this end, the hanger bar (693) may reciprocate in the second mode for a preset first volume time (TV1) such that the thickness of the clothing mounted in the first chamber (100) becomes greater than or equal to the thickness of the clothing before it is mounted inside the first chamber, and then, when the first volume time (TV1) has elapsed, may reciprocate in the fourth mode for a preset second volume time (TV2). Then, when the second volume time (TV2) has elapsed, may reciprocate in the third mode for a preset third volume time (TV3). Furthermore, the hanger bar (693) may repeatedly reciprocate in the second mode during the first volume time (TV1), the fourth mode during the second volume time (TV2), and the third mode during the third volume time (TV3) during a preset total volume time.

[0371] Here, total volume time refers to the total time required to perform the above volume motion.

[0372] In another embodiment of the above volume motion, the second mode, the fourth mode, and the third mode may not be repeated, but may each be performed only once. That is, the total volume time may be divided into three times such that the sum of the first volume time (TV1), the second volume time (TV2), and the third volume time (TV3) is the total volume time, and the second mode, the fourth mode, and the third mode may be performed respectively.

[0373] Therefore, in this case, the second mode, the fourth mode, and the third mode are each performed once, and the sum of the first volume time (TV1), the second volume time (TV2), and the third volume time (TV3) will be the total volume time.

[0374] FIG. 19(a) illustrates an example of a drying motion. A drying motion is a motion for drying wet clothing. Generally, a clothing processing device (1000) supplies steam to a first chamber (100) through a steam unit (250) and can be used for wrinkle removal, deodorization, and sterilization. Therefore, when steam penetrates into clothing placed inside the first chamber (100), the clothing changes from a dry state to a wet state. Thus, a drying motion can be used to dry wet clothing.

[0375] During the initial drying stage when the clothes are wet, you can use Mode 2 to shake them vigorously, and during the middle stage when they are somewhat dry, you can use Mode 3 to shake them. Finally, during the final stage, you can use Mode 1 to gently shake the clothes to dry them.

[0376] To this end, after the steam unit (250) supplies steam to the first chamber (100) for a preset steam supply time, and while the blower unit (220) and heat pump unit (230) are operating to dry the clothes mounted in the first chamber (100), the hanger bar (693) can reciprocate in the first mode for at least a portion of the preset total drying time (TDt).

[0377] Alternatively, after the steam unit (250) supplies steam to the first chamber (100) for a preset steam supply time, and while the blower unit (220) and heat pump unit (230) are operating to dry the clothes mounted in the first chamber (100), the hanger bar (693) may reciprocate in the second mode for a preset first drying time (TD1), and when the first drying time (TD1) has elapsed, reciprocate in the third mode for a preset second drying time (TD2), and when the second drying time (TD2) has elapsed, reciprocate in the first mode for a preset third drying time (TD3).

[0378] Unlike other motions, in the drying motion, various modes are not performed repeatedly, but the sum of the first drying time (TD1), the second drying time (TD2), and the third drying time (TD3), in which the second mode, the third mode, and the first mode are performed once each, can become the total drying time (TDt).

[0379] The above drying motion can be performed simultaneously with the operation of the heat pump unit (230), and the operation of the heat pump unit (230) can be confirmed by whether the compressor (234) is operated. This is because the refrigerant must be compressed and circulated to exchange heat with the air sucked in from the first chamber (100).

[0380] FIG. 19(b) illustrates an example of a fur restoration motion. When using a fabric made of animal fur, such as fur or rabbit fur, or similar artificial fur, the fur may be flattened, resulting in an unsightly appearance. In such cases, a restoration motion can be used to restore the fur to its original state.

[0381] The aforementioned restoration motion utilizes a motion based on D mode combined with B mode. D mode transmits waves with very low frequency and amplitude to the hair to revitalize compressed hair. Additionally, B mode vigorously shakes the hair to facilitate ventilation between the hairs, thereby allowing the entire hair to regain its vitality.

[0382] Therefore, by restoring the flattened hairs to stand up again, the thickness of the garment after performing the restoration motion may be the same as or greater than before performing the restoration motion. This means that the thickness of the garment is the same as or greater than before performing the hair restoration motion.

[0383] That is, the hanger bar (693) may reciprocate in the fourth mode during a preset first restoration time (TF1), and when the first restoration time (TF1) has elapsed, may reciprocate in the third mode during a preset second restoration time (TF2). Furthermore, the hanger bar (693) may repeatedly reciprocate in the fourth mode during the first restoration time (TF1) and the third mode during the second restoration time (TF2) during a preset total restoration time. In this case, after the total restoration time has elapsed, the thickness of the clothing mounted in the first chamber may be greater than or equal to the thickness of the clothing before it was mounted inside the first chamber.

[0384] Meanwhile, as another embodiment of the fur restoration motion, the hanger bar (693) may reciprocate in the fourth mode for a preset first restoration time (TF1), and when the first restoration time (TF1) has elapsed, reciprocate in the third mode for a preset second restoration time (TF2). The fourth mode and the third mode may each be performed only once, and the sum of the first restoration time (TF1) and the second restoration time (TF2) may be equal to the preset total restoration time.

[0385] That is, instead of repeatedly performing the above-mentioned fourth mode and the above-mentioned third mode, the total restoration time can be divided into two parts so that both the third mode and the fourth mode are performed once each. Even in this case, after the above-mentioned total restoration time has elapsed, the thickness of the clothing placed in the above-mentioned first chamber may be greater than or equal to the thickness of the clothing before it was placed inside the above-mentioned first chamber.

[0386] Meanwhile, the above hair restoration motion can be performed after steam is supplied by the steam unit (250).

[0387] As described above, the clothing processing device (1000) comprises a cabinet (10) having an inlet (11) on the front, a first chamber (100) located inside the cabinet (10) and forming a space for receiving clothing through the inlet (11), a second chamber (200) located below the first chamber (100) and forming a space separated from the first chamber (100), a blower unit (220) located inside the second chamber (200) and including a blower fan (226) for sucking in air to circulate the air of the first chamber (100), a heat pump unit (230) including a compressor (234) for compressing refrigerant and connected to the blower unit (220) to discharge dehumidified and heated air to the first chamber (100) through a heat exchanger (not shown), a steam unit (250) located inside the second chamber and generating and supplying steam, and the A water supply tank (310) located in front of the second chamber (200) and supplying water to the steam unit (250); a drainage tank (330) located in front of the second chamber (200) and storing condensate generated in the first chamber (100) and the heat pump unit (230); a hanger bar (693) located in the first chamber (100) and holding clothing accommodated in the first chamber (100); a motor (620) that generates rotational force; a vibrating body (630) that supports the motor (620) and vibrates alternately in a first rotational direction and a second rotational direction opposite to the first rotational direction by the rotation of the motor (620); and a hanger bar (693) that rotates in unison with the vibrating body (630) and is connected to the hanger bar (693) so that the vibration of the vibrating body (630) follows a preset direction of motion, and the hanger bar (693) The drive unit (610) includes a motion conversion unit (680) that converts to enable reciprocating motion, and the hanger bar (693) can reciprocate with different amplitudes and periods (or frequencies) depending on the rotational speed of the motor (620) while at least one of the blower unit (220), the heat pump unit (230), and the steam unit (250) is in operation.

[0388] The above-described clothing processing device (1000) can perform various clothing management functions as described above. For example, it can perform wrinkle removal motion, drying motion, dust removal motion (or dust brushing motion), fur restoration motion, and volume motion. To perform the above various motions, the control unit (270) can reciprocate the hanger bar in combination of various modes.

[0389] Referring to FIGS. 2 and FIGS. 21, the drive unit (610), the steam unit (250), the blower unit (220), the heat pump unit (230), the water supply pump (319) that supplies water to the water supply tank, and the drainage pump (339) that discharges condensate collected in the sump (not shown) to the drainage tank (330) can be controlled. The control unit can control the rotational speed of the motor (620) included in the drive unit (610). Also, the control unit (270) can control the rotational speed of the blower fan (226) included in the blower unit (220). Additionally, the control unit (270) can control the compressor (234) that controls the refrigerant. And it can control the heater (2501) that heats the water contained in the storage unit (251) to generate steam.

[0390] By controlling the blower fan (226), the compressor (234), the heater (2501), and the motor (620), the control unit (270) can develop a course for processing clothing by utilizing a plurality of modes and a motion that is a combination of the plurality of modes.

[0391] FIG. 20 illustrates an example of a course for processing clothing using the aforementioned modes and motions. Here, a course refers to a combination of various motions performed for a predetermined course time. Accordingly, the course time will be set to be longer than the motion time. Additionally, the motion time will be set to be equal to or longer than the time set for each of at least one mode required to perform the clothing management function.

[0392] FIG. 20(a) illustrates an example of a course including a steam supply course, a wrinkle removal course, and a drying course. The course may further include a preheating course before the steam supply course. Additionally, the course may further include a waiting course between the steam supply course and the wrinkle removal course.

[0393] Here, the above steam supply process, the above standby process, and the above wrinkle removal process may be referred to as a refresh process. This is because, in order to sterilize, deodorize, and remove wrinkles from the clothing, steam supply and the shaking of the clothing through the reciprocating motion of the hanger bar (693) are required.

[0394] Here, a step (or process) refers to a sequential process distinguished by the operation and motion (or mode) of the blower fan (226), the compressor (234), and the heater (2501), excluding the motor (620). A course can be formed by combining several steps. The operation of the motor (620) is already included in the mode (or motion). That is, even if the motion is a combination of the same mode, the steps can be distinguished by the operation of the blower fan (226), the compressor (234), and the heater (2501).

[0395] In the case of a conventional garment processing device, the hanger bar reciprocates at the same frequency and period in all strokes. That is, the hanger bar reciprocates at a frequency between 120 RPM (revolutions per minute or reciprocating cycles per minute) and 200 RPM, preferably 180 RPM. However, only the frequency changes, while the amplitude remains the same. This is because, within the above frequency range of the hanger bar, changing the RPM does not have a significant effect on garment processing performance.

[0396] In contrast, the hanger bar (693) of the present disclosure can have a large change in amplitude according to various frequencies due to the harmonic excitation motion of the driving unit (610). Therefore, by utilizing various modes with different frequencies and amplitudes, clothing processing can be performed more effectively.

[0397] After placing the clothing on the hanger bar (693) inside the first chamber (100), the user closes the door (400) and can select a course through the input / output unit (950) provided on the front of the door. Depending on the course selected by the user, the control unit (270) will first heat the heater (2501) to convert the water in the storage unit (251) into steam. This is called a preheating step.

[0398] That is, the above preheating process will be performed before the steam supply process. The above preheating process may be performed during the steam preheating time (P1). The control unit (270) can proceed to the steam supply process when the temperature of the water in the storage unit (251) is measured through the steam temperature sensor (9131) and reaches a temperature at which steam can be generated.

[0399] The above steam preheating time (P1) refers to the time during which the steam unit (250) heats until it reaches the temperature required to convert water into steam through the heater (2501). For example, theoretically, at atmospheric pressure, water will be converted into steam at 100°C.

[0400] Alternatively, if steam is simply generated and begins to be supplied to the first chamber (100), the preheating process can be considered to have progressed to the steam supply process. That is, the steam preheating time (P1) is indicated to distinguish between the preheating process and the steam supply process, but it is not necessary to clearly distinguish them.

[0401] Referring to FIG. 20(b), the hanger bar (693) may reciprocate in a second mode and the blower fan (226) may rotate during the preheating stroke or during the steam preheating time (P1). Alternatively, the hanger bar (693) and the blower fan (226) may operate only during a portion of the preheating stroke. Or, the hanger bar (693) may remain stationary and not operate during the steam preheating time (P1).

[0402] The reason the hanger bar (693) operates in the second mode during the above preheating cycle is to prevent the mounted clothing from falling and blocking the steam supply port (112) during the reciprocating motion of the hanger bar (693). This is because if the clothing blocks the steam injection during the above steam supply cycle, the clothing may be damaged by the steam.

[0403] Therefore, it would be desirable to reciprocate with a smaller amplitude than Mode B during the preheating stroke. However, in order to remove dust attached to the clothing through the preheating stroke, it would be desirable to reciprocate the hanger bar in Mode C, which is the second mode specialized for dust removal.

[0404] When the above steam preheating time (P1) has elapsed, that is, when steam begins to be generated through the steam unit (250), the control unit (270) can start a steam supply process.

[0405] The above steam supply process is carried out during a pre-set steam supply time (P21). During the steam supply time (P21), the hanger bar (693) can reciprocate in the fourth mode. This is to prevent the mounted clothing from falling and covering the steam supply port (112) during the reciprocating motion of the hanger bar (693). Additionally, since the fourth mode, D mode, is effective for steam penetration and moisture retention, it can increase the moisture retention of the clothing, thereby improving wrinkle removal and deodorization effects.

[0406] Referring to FIG. 20(b), during the steam supply time (P21), the blower fan (226) rotates, the heater (2501) continues to heat the water in the storage unit (251), and can inject steam into the first chamber (100) through the steam supply port (112).

[0407] When the above steam supply process is completed, the control unit (270) can perform a standby process for a preset standby time (P22). During the standby process, there is no injection of steam through the steam unit, and the hanger bar (693) can reciprocate in the fourth mode, D mode. That is, the hanger bar (693) can continuously maintain the fourth mode during the steam supply process and the standby process.

[0408] In the above-mentioned air process, the interior of the first chamber (100) will already be filled with wet vapor (or wet saturated vapor) due to the above-mentioned steam supply process. Therefore, additional steam injection may not be necessary.

[0409] Referring to FIG. 20(b), during the steam supply time (P21), the blower fan (226) rotates and the heater (2501) stops heating.

[0410] Through the aforementioned atmospheric process, steam penetrates effectively into the clothing, increasing its moisture content and raising its temperature. This is intended to facilitate effective wrinkle removal in subsequent processes.

[0411] Since the above waiting period is located between the above steam supply period and the above wrinkle removal period, the above waiting time (P22) will be located between the above steam supply period (P21) and the pre-set total wrinkle removal period (P3) to be described later.

[0412] Generally, since the hanger bar (693) reciprocates in the same fourth mode during the steam supply stroke and the standby stroke, they can be grouped together and referred to as the steam supply and standby stroke. The only difference between the steam supply stroke and the standby stroke is whether steam is generated and sprayed through the heater (2501). Referring to FIG. 20(b), in the steam supply stroke, steam is generated and sprayed using the heater (2501), but in the standby stroke, steam is no longer needed, so there is no need to generate steam using the heater (2501).

[0413] Additionally, the control unit (270) can proceed directly to the wrinkle removal process without the waiting process in the steam supply process, thereby changing the mode of the hanger bar (693) to the mode used in the wrinkle removal process.

[0414] The above wrinkle removal process can also be called a cooling process. Although the heat pump unit is not yet operated to dry the moisture contained in the first chamber and the clothing, the temperature inside the first chamber (100) decreases over time because only the blower fan (226) and the hanger bar (693) operate during the wrinkle removal process. After the above wrinkle removal process is completed and the drying process begins, the air in the first chamber will be cooled and dehumidified through the heat pump unit (230) and then heated again. At this time, if the temperature of the air in the first chamber is too high, the cooling efficiency through the heat pump unit (230) may decrease, so it is necessary to lower the air temperature inside the first chamber (100) during the wrinkle removal process in the drying process. Therefore, this can be considered a cooling process.

[0415] In addition, in the above wrinkle removal process, the blower fan (226) and the hanger bar (693) operate, so not only can the temperature of the first chamber and the clothing be lowered, but a drying function can also be performed to some extent.

[0416] In the above wrinkle removal process, the third mode, Mode B, can be used as a base and combined with other modes. This is to change the location of nodes that may occur in the clothing as described above. To this end, after the steam supply time and / or the waiting time has elapsed, the hanger bar (693) may reciprocate in Mode B, the third mode, for at least a portion of the preset total wrinkle removal process time (P3).

[0417] Referring to FIG. 20(a), as an embodiment of the wrinkle removal process, after the steam supply time and / or the waiting time has elapsed, the hanger bar (693) may reciprocate in the third mode during the first wrinkle removal process time (P31). This is referred to as the first wrinkle removal process. Then, after the first wrinkle removal process time (P31) has elapsed, the hanger bar (693) may reciprocate in either the second mode or the fourth mode during a preset second wrinkle removal process time (P32). This is referred to as the second wrinkle removal process.

[0418] The above total wrinkle removal stroke time (P3) may consist only of the above first wrinkle removal stroke time (P31) and the above second wrinkle removal stroke time (P32). If a third wrinkle removal stroke time (P33) is added, the above hanger bar (693) may reciprocate in the remaining one of the above second mode and the above fourth mode during the pre-set third wrinkle removal stroke time (P33) when the above second wrinkle removal stroke time (P32) has elapsed. This is referred to as the third wrinkle removal stroke.

[0419] Referring to FIG. 20(b), the blower fan (226) can rotate during the wrinkle removal process. The blower fan (226) can draw in and circulate humid air inside the first chamber (100) through the air intake port (115). During this process, the heat pump unit (230) does not operate, but due to the circulation of air, the temperature inside the first chamber (100) will drop, and condensation may occur due to the drop in temperature. Additionally, due to the circulation of air, the clothing placed inside the first chamber (100) can be dried to some extent.

[0420] In the above wrinkle removal process, the control unit (270) can change the mode of the hanger bar (693) by changing the rotational speed of the drive unit (610).

[0421] FIG. 20(a) illustrates an embodiment in which three different modes, B mode (third mode), C mode (second mode), and D mode (fourth mode), are used sequentially once each in the wrinkle removal process. However, alternatively, B mode (third mode), C mode (second mode), and D mode (fourth mode) may be performed repeatedly during the total wrinkle removal process time (P3). That is, a single pattern formed using a combination of B mode (third mode), C mode (second mode), and D mode (fourth mode) may be performed repeatedly during the total wrinkle removal process time (P3).

[0422] After the above-mentioned total burr removal process time has elapsed, the control unit (270) can reciprocate the hanger bar (693) in mode A (first mode) and proceed with a drying process that operates the heat pump unit (230). The heat pump unit (230) can suck in the humid air of the first chamber (100) through the blower unit (220), dehumidify and heat the sucked air through heat exchange with the refrigerant, and then supply the high-temperature dry air into the interior of the first chamber (100) through the air supply port (111).

[0423] Therefore, the humidity inside the first chamber (100) can be lowered through high-temperature dry air, and the moisture of the clothing placed inside the first chamber (100) can be evaporated to dry the clothing.

[0424] The above drying process can be performed for a preset drying time (P4). During the drying time (P4), the hanger bar can reciprocate in a first mode (A mode).

[0425] Referring to FIG. 20(b), during the drying process, the blower fan (226) rotates and the compressor (234) can operate to circulate the refrigerant used in the heat pump unit (230).

[0426] An example of the course described in this specification (hereinafter referred to as the standard course) is summarized as shown in Table 3 below.

[0427] [Table 3]

[0428]

[0429] Referring to Table 3, in the wrinkle removal process, Mode D can be effective in removing fine dust as described above. In addition, the fibers of furry fabrics can be preserved during this process. Even if the clothing is not completely dry during the wrinkle removal process, fine dust can be removed by using Mode D.

[0430] The above administrations take into account the amplitude and frequency of the hanger bar (693), as well as other components of the garment processing device (1000), as illustrated in FIG. 20(b). Referring to FIG. 20(b), in the standard course, when the hanger bar reciprocates, the blower fan can also rotate together.

[0431] In addition, in the above standard course, the hanger bar (693) can always reciprocate and the blower fan (226) can rotate. That is, by changing the amplitude and frequency of the hanger bar (693), the hanger bar (693) can be reciprocated in a mode optimized for each stroke, and at the same time, the air inside the first chamber (100) can be circulated through the blower fan (226).

[0432] Additionally, in the above drying process, the compressor (234) operates to compress and circulate the refrigerant, and the hanger bar (693) can reciprocate in the first mode.

[0433] In each cycle, the rotational speed of the blower fan (226) may vary similarly to that of the hanger bar (693). For example, in the preheating cycle, the blower fan (226) may rotate at a first rotational speed. In the steam supply cycle and the standby cycle, the blower fan (226) may rotate at a second rotational speed and a third rotational speed, respectively. In the wrinkle removal cycle, the blower fan (226) may rotate at a fourth rotational speed. In the drying cycle, the blower fan (226) may rotate at a fifth rotational speed. The first rotational speed, the second rotational speed, the third rotational speed, the fourth rotational speed, and the fifth rotational speed may be the same or different from each other.

[0434] In addition, the rotational speed of the blower fan in the first wrinkle removal stroke time (P31) may be different from at least one of the rotational speed of the blower fan in the second wrinkle removal stroke time TW2 and the rotational speed of the blower fan in the third wrinkle removal stroke time (P32).

[0435] In addition, the rotational speed of the blower fan (226) can be varied according to the degree of dryness and the concentration of dust in each administration. That is, the humidity, dust concentration, etc. inside the first chamber can be detected through the drying sensor unit (915) or the dust sensor unit (911), and the control unit (270) can change the rotational speed of the blower fan (226).

[0436] Likewise, the rotational speed of the compressor (234) during the drying process is not maintained at a constant level but can vary depending on the humidity (dryness) and temperature inside the first chamber. That is, by determining the temperature and humidity inside the first chamber through the temperature sensor (913) installed in the inlet duct or air intake port (115) and the drying sensor unit (915), the control unit (270) can change the compression speed of the compressor (234) and the rotational speed of the blower fan (226).

[0437] FIG. 21 is a block diagram briefly illustrating the control configuration of a clothing processing device according to an example of the present disclosure.

[0438] The control unit (270) may be provided in the second chamber (200), but this is merely one embodiment, and it may be provided anywhere, such as inside the door or in the space between the cabinet and the first chamber, as long as it can control the components of the clothing processing device. The control unit (270) can turn on the power unit (900) according to user input to receive power necessary for operating the clothing processing device (1000). In addition, the power unit (900) can be turned off when the course or menu selected by the user is completed.

[0439] In addition, the control unit (270) can detect user input through an input / output unit provided on the front (not shown) of the door and display the current operating status of the clothing processing device or an error.

[0440] The control unit (270) can receive information necessary for clothing processing through the sensor unit (910). For example, the sensor unit (910) may include a water level sensor unit (917). The water level sensor unit (917) can detect the water level of the water supply tank (310) and the drainage tank (330). In addition, it can determine whether the water supply tank (310) and the drainage tank (330) are installed in the tank installation space (351).

[0441] The sensor unit (910) may further include a temperature sensor unit (913) for detecting temperature. The temperature sensor unit (913) may include a steam temperature sensor (9131) provided in the steam unit (250). Additionally, the control unit (270) can determine the temperature inside the first chamber (100) through a temperature sensor (not shown) provided inside the inlet duct (221) or near the air intake port (115) via the temperature sensor unit (913).

[0442] The sensor unit (910) may further include a dryness sensor unit (915) for detecting dryness. The dryness sensor unit (915) is provided on the inner surface of the first chamber (100) to measure the dryness (or humidity) of the first chamber (100).

[0443] As described above, the sensor unit (910) may further include a dust sensor unit (911) for measuring the concentration of dust inside the inner surface of the first chamber (100), the air intake port (115), or the inlet duct (221). Additionally, the sensor unit (910) may further include a door sensor unit (919) for detecting whether the door is open or closed.

[0444] When the course selected by the user is detected through the input / output unit (950), the control unit (270) can control the blower unit (220), the heat pump unit (230), the steam unit (250), and the drive unit (610) to proceed with a preset motion or mode in sequence. Strictly speaking, it can control the rotational speed of the blower fan (226), the rotational speed of the motor inside the compressor (234), the on / off of the heater, and the motor (620) of the drive unit (610).

[0445] FIG. 22 is a flowchart illustrating an example of a control method for a clothing care course. If the course disclosed in FIG. 20 is referred to as the standard course, FIG. 22 illustrates an example of a control method for the standard course. When a user selects the standard course, the control method of the present disclosure may initiate a preheating step (S100) in which the water in the storage unit (251) is heated through a heater (2501) to supply steam through a preset preheating steam unit (250). In the preheating step (S100), the hanger bar (693) may reciprocate in a third mode. Also, the blower fan may rotate at a first rotational speed. The steam unit (250) only heats the water through the heater and cannot yet spray steam into the first chamber (100). The preheating step (S100) may proceed for a preset steam preheating time (P1).

[0446] When the above steam preheating time has elapsed, the control method of the present disclosure may proceed to a steam supply step (S300) in which steam generated in the steam unit (250) is supplied to the first chamber (100) through the steam supply port (112) during a preset steam supply time (P21). In the steam supply step (S300), the hanger bar (693) may reciprocate in a fourth mode, and the blower fan may rotate at a second rotational speed.

[0447] When the above steam supply time (P21) has elapsed, the control method of the present disclosure may proceed to a waiting step (S500) in which the garment is exposed to steam without steam injection for a preset waiting time (P22). Since sufficient steam has already been supplied in the steam supply step (S300), the garment is sufficiently exposed to steam during the waiting time (P22) so that the steam can penetrate the garment and the garment can absorb moisture. In the waiting step (S300), the blower fan (226) may rotate at a third rotational speed, and the hanger bar (693) may reciprocate in a fourth mode, similar to the steam supply step (S200). And the heater (2501) will be turned off.

[0448] When the above waiting time (P22) has elapsed, the control method of the present disclosure may proceed to a wrinkle removal step (S700) for removing wrinkles from the clothing during a preset total wrinkle removal process time (P3). In the wrinkle removal step (S700), the blower fan (226) may rotate at a fourth rotational speed. Depending on the mode of the hanger bar (693), the wrinkle removal step (S700) may be subdivided. The control method of the present disclosure may perform a first wrinkle removal step (S710) of reciprocating the hanger bar (693) in a third mode during a preset first wrinkle removal stroke time (P31), a second wrinkle removal step (S720) of reciprocating the hanger bar (693) in a second mode during a preset first wrinkle removal stroke time (P32) when the first wrinkle removal stroke time (P31) has elapsed, and a second wrinkle removal step (S720) of reciprocating the hanger bar (693) in a fourth mode during a preset third wrinkle removal stroke time (P33) when the second wrinkle removal stroke time (P32) has elapsed.

[0449] Through the above wrinkle removal step (S700), the clothing processing device (1000) can remove wrinkles from the clothing, remove fine dust, restore volume, and restore flattened hair.

[0450] When the above total wrinkle removal stroke time (P3) has elapsed, the control method of the present disclosure may proceed to a drying step (S900) in which the heat pump unit (230) is operated for a preset drying time (P4) to dehumidify and heat the air inside the first chamber (100) and dry the clothing. The control method of the present disclosure may convert the humid air sucked in from the first chamber (100) into high-temperature dry air through the heat pump unit (230) and supply it back to the first chamber (100). Through this, the humidity inside the first chamber (100) can be lowered and the clothing can be dried. During the drying time (P4), the blower fan (226) may rotate at a fifth rotational speed. In addition, the control method of the present disclosure may drive the compressor (234) to operate the heat pump unit (230).

[0451] The present disclosure may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Therefore, if a modified embodiment includes the components of the claims of the present disclosure, it should be considered to fall within the scope of the present disclosure.
